Hologic and Cytyc urge you to read carefully the entire joint proxy statement/prospectus because the information in this section does not provide all the information that might be important to you with respect to the merger and the other matters being considered at the stockholders’ meetings. Additional important information is also contained in the annexes to and the documents incorporated by reference into this joint proxy statement/prospectus.

Q: | Why am I receiving this joint proxy statement/prospectus?

A: | Hologic and Cytyc are proposing to combine the two companies in a merger transaction pursuant to the terms of a merger agreement that is described in this joint proxy statement/prospectus. In the merger, Cytyc will be merged with and into a wholly owned subsidiary of Hologic that was formed for the purpose of the merger, with the Hologic subsidiary surviving the merger and remaining a wholly owned subsidiary of Hologic under the name “Cytyc Corporation.” A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A.

| In order to complete the merger, Hologic stockholders must approve an amendment to Hologic’s charter to increase the number of authorized shares of Hologic common stock and approve the issuance of shares of Hologic common stock in connection with the merger, and Cytyc stockholders must adopt the merger agreement and the transactions contemplated thereby, including the merger. In addition, all other conditions to the merger must be satisfied or waived.

| Neither the amendment to the Hologic charter nor the issuance of Hologic common stock in connection with the merger will take place unless both of these proposals are approved by Hologic stockholders and the merger is completed. Hologic will hold a special meeting of its stockholders, referred to as the Hologic special meeting, to obtain the required approvals of Hologic stockholders, and Cytyc will hold a special meeting of its stockholders, referred to as the Cytyc special meeting, to obtain the required approval of Cytyc stockholders.

Q: | What will I receive in the merger?

A: | Hologic stockholders. Each share of Hologic common stock held by Hologic stockholders immediately before the merger will continue to represent one share of Hologic common stock after the effective time of the merger. In other words, Hologic stockholders will receive no consideration in the merger and the merger will not change the number of shares a Hologic stockholder currently owns.

| Cytyc stockholders. For each share of Cytyc common stock held immediately before the effective time of the merger, Cytyc stockholders will have the right to receive 0.52 of a share of Hologic common stock and $16.50 in cash without interest. Cytyc stockholders will also receive cash for any fractional shares of Hologic common stock that they would otherwise receive in the merger. The amount of cash for fractional shares will be calculated by multiplying the fraction of a share of Hologic common stock to which the Cytyc stockholder would be entitled to receive in the merger by the closing sale price of a share of Hologic common stock on the closing date of the merger.

| Hologic and Cytyc expect that, upon completion of the merger, assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024, approximately 55% of the outstanding common stock of Hologic will be held by former Cytyc stockholders, and approximately 45% of the outstanding common stock of Hologic will be held by current Hologic stockholders.

Q: | How will Hologic pay for the cash portion of the merger consideration?

A: | Hologic has received a firm financing commitment from Goldman Sachs Credit Partners L.P., Bank of America, N.A., Banc of America Securities LLC, Banc of America Bridge LLC, Citigroup Global Markets Inc., JPMorgan Chase Bank, N.A., and J.P. Morgan Securities Inc., collectively referred to as the arrangers, in which the arrangers committed to provide, in the aggregate, financing of up to approximately $2.55 billion to pay for the cash portion of the merger consideration, for repayment of existing debt of Hologic and Cytyc, for expenses relating to the merger and for working capital following the completion of the merger. For a more detailed description of the terms of the financing and the commitment letter, see “The Merger—Financing of the Merger” beginning on page 58, and for information about certain risks related to the financing, see “Risk Factors—Risks Related to Indebtedness of the Combined Company” beginning on page 29.

Q: | Is the merger expected to be taxable to stockholders?

A: | Hologic and Cytyc intend for the merger to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code. If you are a Cytyc stockholder, you generally will recognize income or gain for U.S. federal income tax purposes equal to the lesser of (i) the amount of cash (excluding cash that you receive in lieu of fractional shares of Hologic common stock) that you receive and (ii) the amount of gain that you realize, which generally is equal to the sum of (a) the amount of cash that you receive plus (b) the fair market value of any Hologic common stock that you receive, over your tax basis in the shares of Cytyc common stock that you surrender pursuant to the merger. In addition, if you receive cash in lieu of a fractional share of Hologic common stock, you will recognize gain or loss based on the difference between the cash you receive for such fractional share and your tax basis allocable to the fractional share.

| You should read “Material United States Federal Income Tax Consequences of the Merger” beginning on page 110 for a more complete discussion of the United States federal income tax consequences of the merger.

| If you are a Hologic stockholder, you will simply retain your shares of Hologic common stock, and the merger therefore will not be taxable to you.

| Tax matters can be complicated and the tax consequences of the merger to you will depend on your particular tax situation. We recommend that you consult your tax advisor to determine the tax consequences of the merger to you.

Q: | When and where are the Hologic and Cytyc special meetings?

A: | Hologic special meeting. The Hologic special meeting will be held on [ ], 2007 at 9:00 a.m., local time, at Hologic’s principal executive offices located at 35 Crosby Drive, Bedford, Massachusetts 01730, to consider and vote on the proposals related to the merger and certain other proposals.

The Merger

The Agreement and Plan of Merger, dated as of May 20, 2007, among Hologic, Cytyc and Nor’easter Corp., which is referred to as the merger agreement, is attached as Annex A to this joint proxy statement/prospectus. Cytyc and Hologic encourage you to read carefully the merger agreement in its entirety because it is the principal legal agreement that governs the merger.

Structure of the Merger (see page 116)

Subject to the terms and conditions of the merger agreement, at the effective time of the merger, Cytyc will merge with and into Nor’easter Corp., a wholly owned subsidiary of Hologic that was formed for the purpose of the merger, with Nor’easter Corp. surviving the merger as a direct, wholly owned subsidiary of Hologic. At the effective time of the merger, Nor’easter Corp. will be renamed “Cytyc Corporation.”

Merger Consideration (see page 116)

Cytyc stockholders. As a result of the merger, Cytyc stockholders will be entitled to receive, for each issued and outstanding share of Cytyc common stock that they own immediately prior to the effective time of the merger, 0.52 of a share, referred to as the exchange ratio, of Hologic common stock, referred to as the stock merger consideration, and $16.50 in cash without interest, referred to as the cash merger consideration. The combined company will not issue any fractional shares of Hologic common stock in the merger. Instead, Cytyc stockholders will receive cash in lieu of any fractional shares of Hologic common stock that they would have otherwise received in the merger. The amount of cash for fractional shares will be calculated by multiplying the fraction of a share of Hologic common stock to which the Cytyc stockholder would be entitled to receive in the merger by the closing sale price of a share of Hologic common stock on the closing date of the merger. The stock merger consideration, together with the cash merger consideration and any cash received in lieu of fractional shares, is referred to as the merger consideration.

Hologic stockholders. Hologic stockholders will continue to own their existing shares of Hologic common stock after the merger. Hologic stockholders should not send in their stock certificates in connection with the merger.

Ownership of the Combined Company After the Merger

Hologic will issue approximately 64.8 million shares of Hologic common stock to Cytyc stockholders in the merger based on the number of shares of Cytyc common stock outstanding on May 31, 2007, assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024. At the completion of the merger, it is expected that there will be outstanding approximately 118.6 million shares of common stock of the combined company. The shares of Hologic common stock issued to former Cytyc stockholders in the merger will represent approximately 55% of the outstanding common stock of the combined company immediately after the merger. Shares of Hologic common stock held by current Hologic stockholders will represent approximately 45% of the outstanding common stock of the combined company immediately after the merger.

When you consider the Hologic and Cytyc board of directors’ respective recommendations that stockholders vote in favor of the proposals described in this joint proxy statement/prospectus, you should be aware that (i) some Cytyc executive officers and directors may have interests that may be different from, or in addition to, Cytyc stockholders’ interests, including but not limited to, their receipt of change of control payments under existing Cytyc change of control agreements in connection with the merger, entry into new change of control agreements and retention and severance agreements with Hologic, new employment arrangements with Hologic, accelerated vesting of Cytyc stock options and other equity awards at the effective time of the merger, and the right of Cytyc’s executive officers and directors to continued indemnification and insurance coverage for acts or omissions occurring before the merger; and (ii) some Hologic executive officers and directors may have interests that may be different from, or in addition to, Hologic stockholders’ interests, including but not limited to, accelerated vesting of stock options and other equity awards upon completion of the merger, payments under change of control agreements in connection with the merger, and a new retention and severance agreement for one executive officer.

Appraisal Rights (see page 106)

Under the General Corporation Law of the State of Delaware, referred to as the DGCL, instead of receiving the merger consideration, Cytyc stockholders are entitled to demand to have the “fair value” of their shares at the effective time of the merger judicially determined and paid to them in cash. A stockholder who desires to exercise appraisal rights must (i) not vote in favor of the merger, (ii) deliver a written demand for appraisal of his or her shares to the corporate secretary of Cytyc before the vote on the merger at the Cytyc special meeting and (iii) otherwise comply with the provisions of the DGCL. You should carefully read and follow the instructions under “The Merger—Appraisal Rights” commencing on page 106 if you wish to exercise your appraisal rights.

Under the DGCL, Hologic stockholders have no right to an appraisal of the “fair value” of their shares in connection with the merger.

Material United States Federal Income Tax Consequences of the Merger (see page 110)

Hologic and Cytyc intend for the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code. If you are a Cytyc stockholder, you generally will recognize income or gain for U.S. federal income

tax purposes equal to the lesser of (i) the amount of cash (excluding cash that you receive in lieu of fractional shares of Hologic common stock) that you receive and (ii) the amount of gain that you realize, which generally is equal to the sum of (a) the amount of cash that you receive plus (b) the fair market value of any Hologic common stock that you receive, over your tax basis in the shares of Cytyc common stock that you surrender pursuant to the merger. Your income or gain may vary if you acquired your Cytyc common stock in more than one transaction. In addition, if you receive cash in lieu of a fractional share of Hologic common stock, you will recognize gain or loss based on the difference between the cash you receive for such fractional share and your tax basis allocable to the fractional share.

You should read “Material United States Federal Income Tax Consequences of the Merger” beginning on page 110 for a more complete discussion of the U.S. federal income tax consequences of the merger.

If you are a Hologic stockholder, you will simply retain your shares of Hologic common stock, and the merger therefore will not be taxable to you.

Tax matters can be complicated and the tax consequences of the merger to you will depend on your particular tax situation. We recommend that you consult your tax advisor to determine the tax consequences of the merger to you.

Accounting Treatment (see page 104)

Hologic prepares its financial statements in accordance with U.S. GAAP. The merger will be accounted for using the purchase method of accounting. As discussed under “The Merger—Accounting Treatment” on page 104, based upon the terms of the merger agreement and other factors, such as the composition of the combined company’s board and senior management, Hologic is considered to be the acquirer of Cytyc for accounting purposes. This means that Hologic will allocate the purchase price to the fair value of Cytyc’s assets and liabilities at the effective time of the merger, with the excess purchase price being recorded as goodwill. Under the purchase method of accounting, goodwill is not amortized but is tested for impairment at least annually.

Regulatory Approvals (see page 113)

Hologic and Cytyc have each agreed to use their reasonable best efforts in order to obtain all regulatory approvals required in order to complete the merger. These approvals include approvals by the U.S. Federal Trade Commission, the U.S. Department of Justice and state antitrust authorities. Hologic and Cytyc each submitted their antitrust filings with the U.S. Department of Justice and the U.S. Federal Trade Commission on June 1, 2007, which commenced the initial waiting period of 30 days. Based on the review and analyses performed, Hologic and Cytyc do not believe that any other antitrust related filings are required in any foreign jurisdictions. Although Hologic and Cytyc do not expect regulatory authorities to raise any significant objections in connection with their review of the merger, Hologic and Cytyc cannot assure you that they will obtain all required regulatory approvals or that these regulatory approvals will not contain terms, conditions or restrictions that would be detrimental to the combined company after the completion of the merger.

Listing of Hologic Common Stock (see page 127)

Hologic has agreed to use its commercially reasonable efforts to cause the shares of Hologic common stock to be issued in the merger to be approved for listing on the Nasdaq Global Select Market.

The merger consideration is fixed in the merger agreement and will not be adjusted for changes in the market value of the common stock of Hologic or Cytyc. One result of this is that the market value of the Hologic common stock that Cytyc stockholders will receive in the merger may vary significantly from the prices shown in the table below.

|  | Cytyc Common Stock |  |  | Hologic Common Stock |  |  | Implied Value of Cytyc Common Stock |
May 18, 2007 |  | $ | 35.05 |  |  | $ | 57.61 |  |  | $ | 46.46 |
[ ], 2007 |  | $ | [ | ] |  | $ | [ | ] |  | $ | [ | ]

Cytyc stockholders should obtain current market prices for shares of Hologic common stock and Cytyc common stock in deciding whether to vote for the adoption of the merger agreement and the transactions contemplated thereby, including the merger. Hologic stockholders should obtain current market prices for shares of Hologic and Cytyc common stock in deciding whether to vote for the approval of the amendment to the Hologic charter to increase the number of authorized shares of Hologic common stock and the issuance of Hologic common stock to Cytyc stockholders in the merger.

Dividends

Hologic has never declared or paid cash dividends on its capital stock and does not plan to pay any cash dividends in the foreseeable future. Hologic’s current policy is to retain all of its earnings to finance future growth. In addition, Hologic’s $150 million credit facility with Bank of America N.A., as administrative agent, prohibits it from declaring or paying any cash dividends. The proposed new credit facilities expected to be obtained by Hologic in connection with the merger will also contain restrictions on the payment of dividends following the merger.

Cytyc has never declared nor paid cash dividends on its capital stock and does not expect to pay any cash dividends in the foreseeable future.

RISK FACTORS

In addition to the other information included in or incorporated by reference into this joint proxy statement/prospectus, including the matters addressed in “Cautionary Statement Regarding Forward-Looking Statements” below and the additional risks relating to Cytyc included in Annex B of this joint proxy statement/prospectus under the heading “Information about Cytyc—Risk Factors,” you should carefully consider the following risk factors before deciding whether to vote for the adoption of the merger agreement and the transactions contemplated thereby, including the merger, in the case of Cytyc stockholders, or for the amendment to the Hologic charter or the issuance of shares of Hologic common stock in the merger, in the case of Hologic stockholders. If any of the risks described below, elsewhere in this joint proxy statement/prospectus or in the periodic reports incorporated by reference into this joint proxy statement/prospectus actually occurs, the respective businesses, financial results, financial condition, operating results or stock prices of Hologic, Cytyc or the combined company could be materially adversely affected. See “Where You Can Find More Information,” beginning on page 192 and Annex B, “Information about Cytyc—Risk Factors.”

RISKS RELATED TO THE MERGER

Because the market price of Hologic common stock may fluctuate, and the closing date of the merger is not yet ascertainable, Cytyc stockholders cannot be certain of the precise value of the merger consideration they will receive in the merger.

Upon completion of the merger, each share of Cytyc common stock outstanding immediately prior to the merger will be cancelled and converted into the right to receive merger consideration equal to 0.52 of a share of Hologic common stock and $16.50 in cash. The merger consideration is fixed and will not be adjusted due to any increases or decreases in the price of Hologic common stock or Cytyc common stock. However, the value of Hologic common stock to be received by Cytyc stockholders in the merger will depend upon the market price of a share of Hologic common stock upon the completion of the merger. Therefore, if the price of Hologic common stock declines, Cytyc stockholders will receive less value for their shares upon the completion of the merger than the implied value of the merger consideration calculated on the date the merger agreement was signed or on the date of the Cytyc special meeting.

The merger may not be completed until a period of time after the Hologic special meeting and the Cytyc special meeting, during which time the market value of Hologic common stock and Cytyc common stock will likely fluctuate. Therefore, at the time of their respective special meetings, Hologic and Cytyc stockholders will not know the exact market value of Hologic common stock that will be issued in connection with the merger. The market price of a share of Hologic common stock at the time the merger is completed is likely to be different, and may be lower, than it was at the time the merger agreement was signed and at the time of the special meetings. The closing price of Hologic common stock on the Nasdaq Global Select Market on May 18, 2007 was $57.61 per share. From May 21, 2007 through the date of this joint proxy statement/prospectus, the trading price of Hologic common stock ranged from a high of $[ ] per share to a low of $[ ] per share. For Hologic and Cytyc historical market prices, see “Comparative Per Share Market Price and Dividend Information” beginning on page 23.

Stock price changes may result from a variety of factors, including, but not limited to:

| • |  | changes in the business, operations or prospects of Hologic or Cytyc;

| • |  | catastrophic events, both natural and man-made;

| • |  | governmental, litigation and regulatory developments or considerations;

| • |  | quarterly fluctuations in either of the companies’ actual or anticipated operating results;

| • |  | announcements of technological innovations;

| • |  | new products or product enhancements by either of the companies or their respective competitors;

25

##### Table of Contents

| • |  | developments in patents or other intellectual property rights and litigation;

| • |  | developments in relationships with either of the companies’ customers and suppliers;

| • |  | interest rates;

| • |  | general market and economic conditions;

| • |  | market assessments as to whether and when the merger will be completed and market assessments of the condition, results or prospects of either company’s business; and

| • |  | changes in reimbursement rates.

Stockholders of Hologic and Cytyc are urged to obtain current market prices for Hologic and Cytyc common stock when they consider whether to approve the proposals required to complete the merger at their respective special meetings.

Failure to complete the merger could negatively impact the stock prices and the future business and financial results of Hologic and Cytyc.

If the merger is not completed, the ongoing businesses of Hologic or Cytyc may be adversely affected and Hologic and Cytyc will be subject to several risks, including the following:

| • |  | being required, under certain circumstances under the merger agreement, to pay a termination fee of between $50 million and $150 million, in the case of a payment by Cytyc to Hologic, or between $33 million and $100 million, in the case of a payment by Hologic to Cytyc;

| • |  | having to pay significant costs relating to the merger, such as legal, accounting, financial advisor and printing fees;

| • |  | the attention of management of Hologic and Cytyc will have been diverted to the merger instead of on such company’s own operations and pursuit of other opportunities that could have been beneficial to such company; and

| • |  | customer perception may be negatively impacted which could affect the ability of Hologic and Cytyc to compete for, or to win, new and renewal business in the marketplace.

Obtaining required approvals and satisfying closing conditions may delay or prevent completion of the merger or reduce the anticipated benefits of the merger.

Completion of the merger is conditioned upon the receipt of all material governmental authorizations, consents, orders and approvals, including the expiration or termination of the applicable waiting periods under the HSR Act. Hologic and Cytyc intend to pursue all required approvals in accordance with the merger agreement. If the companies do not receive these approvals, or do not receive them on terms that satisfy the conditions set forth in the merger agreement, then neither company will be obligated to complete the merger.

The governmental agencies from which the companies will seek these approvals have broad discretion in administering the governing regulations. As a condition to approval of the merger, agencies may impose requirements, limitations or costs or require divestitures or place restrictions on the conduct of the combined company’s business. These requirements, limitations, costs, divestitures or restrictions could jeopardize or delay the completion of the merger or may reduce the anticipated benefits of the merger. Further, no assurance can be given that the required consents and approvals will be obtained or that the required conditions to closing will be satisfied, and, if all required consents and approvals are obtained and the conditions to the completion of the merger are satisfied, no assurance can be given as to the terms, conditions and timing of the approvals.

##### Table of Contents

The combined company may be unable to successfully integrate Hologic’s and Cytyc’s operations or to realize the anticipated cost savings, revenues and other benefits of the merger. As a result, the value of the combined company’s common stock may be adversely affected.

Hologic and Cytyc entered into the merger agreement because each company believes that the merger will be beneficial to each of Hologic, Cytyc and their respective stockholders. Currently, each company operates as an independent public company. Achieving the anticipated benefits of the merger will depend in part upon whether the two companies integrate their businesses in an efficient and effective manner. The companies may not be able to accomplish this integration process smoothly or successfully. The necessity of coordinating geographically separated organizations, systems and facilities and addressing possible differences in business backgrounds, corporate cultures and management philosophies may increase the difficulties of integration. The companies operate numerous systems, including those involving management information, purchasing, accounting and finance, sales, billing, employee benefits, payroll and regulatory compliance. The integration of certain operations following the merger will require the dedication of significant management resources, which may temporarily distract management’s attention from the day-to-day business of the combined company. Employee uncertainty and lack of focus during the integration process may also disrupt the business of the combined company and result in undesired employee attrition. Any inability of management to successfully integrate the operations of the two companies could have a material adverse effect on the business and results of operations of the combined company. The companies may not be able to achieve the anticipated operating and cost synergies or long-term strategic benefits of the merger. An inability to realize the full extent of, or any of, the anticipated benefits of the merger, as well as any delays encountered in the integration process, could have an adverse effect on the business and results of operations of the combined company, which may affect the value of the shares of the combined company’s common stock after the completion of the merger.

Due to legal restrictions, Cytyc and Hologic have been able to conduct only limited planning regarding the integration of the two companies following the merger and have not yet determined the exact nature of how the businesses and operations of the two companies will be combined after the merger. The actual integration may result in additional and unforeseen expenses, and the anticipated benefits of the integration plan may not be realized.

The combined company will incur significant transaction and merger-related costs in connection with the merger.

Hologic and Cytyc expect to incur significant costs associated with combining the operations of the two companies. The substantial majority of the expenses resulting from the merger will be comprised of transaction costs related to the merger, systems consolidation costs, and business integration and employment–related costs. Hologic and Cytyc will also incur transaction fees and costs related to formulating integration plans. Additional unanticipated costs may be incurred in the integration of the two companies’ businesses. Due to legal restrictions, Cytyc and Hologic have been able to conduct only limited planning regarding the integration of the two companies and have not yet been able to formulate detailed integration plans to deliver anticipated synergies. Although Hologic and Cytyc expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow them to offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

Whether or not the merger is completed, the announcement and pendency of the merger could impact or cause disruptions in Cytyc’s and Hologic’s businesses, which could have an adverse effect on their results of operations and financial condition.

Specifically:

| • |  | current and prospective customers and suppliers of Hologic and Cytyc may experience uncertainty associated with the merger, including with respect to current or future business relationships with Hologic, Cytyc or the combined company and may attempt to negotiate changes in existing business

27

##### Table of Contents

| relationships or consider entering into business relationships with parties other than Hologic, Cytyc or the combined company, either before or after completion of the merger;

| • |  | Cytyc and Hologic employees may experience uncertainty about their future roles with the combined company, which might adversely affect Cytyc’s and Hologic’s ability to retain and hire key employees;

| • |  | if the merger is completed, the accelerated vesting of stock options and other equity-based awards and payment of “change in control” benefits to some members of Cytyc’s and Hologic’s management on completion of the merger could result in increased difficulty or cost in retaining Cytyc’s and Hologic’s officers and employees; and

| • |  | the attention of management of each of Cytyc and Hologic may be directed toward the completion of the merger and transaction-related considerations and may be diverted from the day-to-day business operations of their respective companies.

Certain directors and executive officers of Hologic and Cytyc have interests that may be different from, or in addition to, interests of Hologic and Cytyc stockholders generally.

Some directors and executive officers of Hologic and Cytyc may have interests that differ from yours. For example, some directors and executive officers have employment, indemnification and severance arrangements, rights to acceleration of stock options and other equity-based awards, and other benefits they may receive on a change in control of Hologic or Cytyc, as the case may be, that provide them with interests in the merger that may be different from yours. You should be aware of these interests when you consider your board of directors’ recommendation that you vote in favor of the proposals submitted at your stockholder meeting.

The deal-protection provisions of the merger agreement may deter alternative business combinations and could negatively impact the stock prices of Hologic and Cytyc if the merger agreement is terminated.

As a result of certain provisions of the merger agreement, it is possible that a third party who might be interested in pursuing a business combination proposal with Hologic or Cytyc would be discouraged from doing so. Any such proposal might be advantageous to the stockholders of Hologic and Cytyc when compared to the terms and conditions of the transaction described in this joint proxy statement/prospectus. In particular, the termination fee provision of the merger agreement may deter third parties from proposing alternative business combinations that might result in greater value to Hologic and Cytyc stockholders than the merger. In addition, in the event the merger agreement is terminated by Hologic or Cytyc in circumstances that obligate either party to pay a termination fee to the other party, Hologic’s or Cytyc’s stock price may decline as a result of its payment of the termination fee.

The merger is expected to have a dilutive effect on Hologic’s earnings per share calculated in accordance with U.S. GAAP, which may adversely affect the market price of Hologic’s common stock following the merger.

The merger is expected to have a dilutive effect on earnings per share of Hologic calculated in accordance with U.S. GAAP primarily due to the amortization of the intangible assets in connection with the merger. These expectations are based on preliminary estimates which may materially change after the completion of the merger. The combined company could also encounter additional transaction and integration-related costs or other factors such as the failure to realize all of the benefits anticipated in the merger. All of these factors could cause further dilution to the earnings per share of the combined company or cause a decrease in the price of common stock of the combined company.

Charges to earnings resulting from the application of the purchase method of accounting may adversely affect the market value of the combined company’s common stock following the merger.

In accordance with U.S. GAAP, Hologic will be considered the acquirer of Cytyc for accounting purposes. Hologic will account for the merger using the purchase method of accounting, which will result in charges to the combined company’s earnings that could adversely affect the market value of Hologic’s common stock following

28

##### Table of Contents

the completion of the merger. Under the purchase method of accounting, Hologic will allocate the total purchase price to the assets acquired and liabilities assumed from Cytyc based on their fair values as of the date of the effective time of the merger, and record any excess of the purchase price over those fair values as goodwill. For certain tangible and intangible assets, recording their fair values as of the completion date of the merger will result in the combined company incurring significant additional depreciation and/or amortization expense that exceed the combined amounts recorded by Hologic and Cytyc prior to the merger. This increased expense will be recorded by the combined company over the useful lives of the underlying assets. In addition, to the extent the value of goodwill or intangible assets were to become impaired, the combined company may be required to incur charges relating to the impairment of those assets.

RISKS RELATED TO INDEBTEDNESS OF THE COMBINED COMPANY

Hologic will incur significant indebtedness in order to finance the merger, which will limit the combined company’s operating flexibility, and could adversely affect the combined company’s operations and financial results and prevent the combined company from fulfilling its obligations.

In order to finance the cash portion of the merger consideration and other expenses incurred in connection with the merger, Hologic intends to incur up to approximately $2.55 billion of new indebtedness, including approximately $1.35 billion under a 5.5 year senior secured tranche B term loan facility and approximately $1.0 billion under an 18 month senior secured capital markets term loan facility. Additionally, Hologic will have the ability to incur up to $200 million of additional indebtedness under its proposed new five year revolving credit facility, and certain other of Hologic’s and Cytyc’s current indebtedness may remain outstanding. These new credit facilities are anticipated to bear interest at variable rates dependent upon the credit rating of the combined company. This level of indebtedness may:

| • |  | make it more difficult for the combined company to satisfy its obligations with respect to its outstanding indebtedness;

| • |  | increase the combined company’s vulnerability to general adverse economic and industry conditions, including increases in interest rates;

| • |  | require the combined company to dedicate a substantial portion of its cash flow from operations to interest and principal payments on its indebtedness, which would reduce the availability of its cash flow to fund working capital, capital expenditures, expansion efforts and other general corporate purposes;

| • |  | limit the combined company’s flexibility in planning for, or reacting to, changes in its business and the industry in which it operates;

| • |  | place the combined company at a competitive disadvantage compared to its competitors that have less debt; and

| • |  | limit the combined company’s ability to borrow additional funds for working capital, capital expenditures, general corporate purposes or acquisitions.

In addition, the terms of the financing obligations to be incurred by the combined company in connection with the merger will contain covenants that restrict the combined company’s ability, and that of its subsidiaries, to engage in certain transactions and may impair the combined company’s ability to respond to changing business and economic conditions, including, among other things, limitations on the ability to:

| • |  | incur additional indebtedness;

| • |  | pay dividends and make distributions;

| • |  | repurchase stock;

| • |  | make certain investments;

29

##### Table of Contents

| • |  | create liens;

| • |  | engage in transactions with affiliates;

| • |  | merge with or acquire another company; and

| • |  | transfer and sell assets.

The combined company’s proposed new revolving credit facility is also anticipated to require the combined company to satisfy certain financial covenants.

The combined company’s ability to comply with these provisions may be affected by general economic conditions, political decisions, industry conditions and other events beyond the combined company’s control. The combined company’s failure to comply with the covenants contained in the proposed new credit facilities could result in an event of default, which could materially and adversely affect the combined company’s results of operation and financial condition.

If there were an event of default under one of the combined company’s debt instruments or a change of control of the combined company, the holders of the defaulted debt could cause all amounts outstanding with respect to that debt to be due and payable immediately and may be cross-defaulted to other debt. The combined company’s assets or cash flow may not be sufficient to fully repay borrowings under its outstanding debt instruments if accelerated upon an event of default, and there is no guarantee that the combined company would be able to repay, refinance or restructure the payments on those debt securities.

See “The Merger—Financing of the Merger” beginning on page 58.

The combined company may not be able to generate sufficient cash flow to service all of its obligations, including its obligations under its new credit facilities.

The combined company’s ability to make payments on and to refinance its indebtedness, including the indebtedness incurred under the proposed new credit facilities, and to fund planned capital expenditures, strategic transactions and expansion efforts will depend on the combined company’s ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond the control of the combined company.

The combined company’s business may not be able to generate sufficient cash flow from operations, and the combined company cannot assure that future borrowings will be available to it in amounts sufficient to enable it to pay its indebtedness as such indebtedness matures and to fund its other liquidity needs. If this is the case, the combined company will need to refinance all or a portion of its indebtedness on or before maturity, and there can be no assurance that it will be able to refinance any of its indebtedness, including its new credit facilities, on commercially reasonable terms, or at all. The combined company may need to adopt one or more alternatives, such as reducing or delaying planned expenses and capital expenditures, selling assets, restructuring debt, or obtaining additional equity or debt financing. These financing strategies may not be affected on satisfactory terms, if at all. The combined company’s ability to refinance its indebtedness or obtain additional financing, or to do so on commercially reasonable terms, will depend on, among other things, its financial condition at the time, restrictions in agreements governing its indebtedness, and other factors, including the condition of the financial markets and the markets in which the combined company will compete.

If the combined company does not generate sufficient cash flow from operations, and additional borrowings, refinancings or proceeds of asset sales are not available to it, the combined company may not have sufficient cash to enable it to meet all of its obligations.

##### Table of Contents

The combined company may not be able to effect its plans for a refinancing of a substantial portion of its new credit facilities with convertible debt or other equity or equity-linked financing, which could adversely affect the combined company’s liquidity and results of operations, and, even if completed, such refinancing could result in substantial dilution to existing stockholders of the combined company.

As soon as practicable after the effective time of the merger, Hologic intends to cause the combined company to refinance a substantial portion of the debt incurred under the proposed new credit facilities with convertible debt or other equity or equity-linked financing, with reduced interest rates, extended maturity and limited or no restrictive or other financial covenants. The combined company’s ability to effect this refinancing on commercially reasonable terms will depend on, among other things, its financial condition at the time and other factors, including the condition of the financial markets and the markets in which the combined company will compete. The combined company cannot assure that it will be able to effect this refinancing on a timely basis or on favorable terms, if at all, or that such financing will not result in significant dilution to existing stockholders. Failure of the combined company to effect timely such a refinancing would likely result in an increase in the ongoing interest expense and restrictive covenants, and could otherwise adversely effect the combined company’s liquidity and results of operations.

The combined company will be required to enter into hedging transactions for its variable interest rate exposure under its proposed new credit facilities which could adversely affect its ability to repay all or a portion of those facilities without incurring additional costs, and will subject the combined company to risks of default by the counterparties to those transactions.

The terms of the combined company’s proposed new credit facility will obligate the combined company to enter into hedging transactions to hedge a substantial portion of the interest rate risk under those facilities. If the combined company repays, redeems or repurchases (voluntarily or mandatorily) all or a portion of its new credit facilities prior to their scheduled maturities, the combined company’s obligations under those hedging transactions may cease to match the combined company’s obligations under the credit facilities, and could result in significant additional expense to the combined company. These hedging transactions may not qualify for effective hedge treatment in accordance with U.S. GAAP and as a result, any changes in fair value of hedge contracts could be required to be recorded to the statement of income. In addition, default by the counterparties to the combined company’s hedging transactions could result in the combined company having to make interest payments at the variable rates payable under the new credit facilities and expose the combined company further to interest rate fluctuation risk under those credit facilities.

RISKS RELATED TO HOLOGIC, CYTYC AND COMBINED COMPANY

Sales and market acceptance of the combined company’s products will be dependent on third party reimbursement. Failure of third party payors to provide appropriate levels of reimbursement for use of the combined company’s products could harm the combined company’s business and prospects.

Sales and market acceptance of the combined company’s medical products in the United States and other countries will be dependent on the reimbursement of patient’s medical expenses by government healthcare programs and private health insurers. The costs of Hologic’s and Cytyc’s products to customers are substantial, and market acceptance of the combined company’s products will continue to depend upon their customers’ ability to obtain an appropriate level of reimbursement from third-party payors for use of their products. In the United States, the Centers for Medicare & Medicaid Services, known as CMS, establish guidelines for the reimbursement of healthcare providers treating Medicare and Medicaid patients. Under current CMS guidelines, varying reimbursement levels have been established for Hologic’s and Cytyc’s products and procedures. The actual reimbursement amounts are determined by individual state Medicare carriers and, for non-Medicare and Medicaid patients, private insurance carriers. There are often delays between the reimbursement approvals by CMS and by a state Medicare carrier and private insurance carriers. Moreover, states as well as private insurance carriers may choose not to follow the CMS reimbursement guidelines. The use of the combined company’s products outside the United States will be similarly affected by reimbursement policies adopted by foreign governments’ reimbursements and regulatory positions and insurance carriers.

31

##### Table of Contents

In November 2006, the CMS announced reductions to the 2007 reimbursement levels for bone density assessments, CAD and breast biopsy. The most significant reductions applicable to the combined company’s products were an approximately 40% decline in 2007 in reimbursement for osteoporosis (DXA) testing, which increases to an approximately 70% decline over four years, an approximately 30% decline in 2007 in reimbursement for stereotactic biopsy, which increases to an approximately 63% decline over four years, and an approximately 16% decline in reimbursement for CAD in 2007, which increases to an approximately 50% decline over four years. These reductions or any other reduction or adverse change in reimbursement policies for the use of the combined company’s products could harm the combined company’s business and prospects.

The combined company’s business may be harmed by Hologic’s and Cytyc’s recently completed acquisitions.

Hologic and Cytyc have recently acquired a number of businesses, technologies, product lines, and products, including Suros Surgical Systems, Inc., R2 Technology, Inc. and AEG Elektrofotografie GmbH, in the case of Hologic, and Adeza Biomedical Corporation and Adiana, Inc., in the case of Cytyc. In addition, Hologic has recently entered into an agreement to acquire BioLucent, Inc. The success of these acquisitions will depend on the combined company’s ability to realize the anticipated benefits from combining the acquired businesses with the combined company’s business. The combined company may fail to realize these anticipated benefits for a number of reasons, including the following:

| • |  | problems may arise with the combined company’s ability to successfully integrate the acquired businesses, which may result in the combined company not operating as effectively and efficiently as expected, and may include:

| • |  | diversion of management time, as well as a shift of focus from operating the businesses to issues related to integration and administration or inadequate management resources available for integration activity and oversight;

| • |  | failure to retain and motivate key employees;

| • |  | failure to successfully manage relationships with customers, distributors and suppliers;

| • |  | failure of customers to accept new products;

| • |  | failure to effectively coordinate sales and marketing efforts;

| • |  | failure to combine product offerings and product lines quickly and effectively;

| • |  | failure to effectively enhance acquired technology and products or develop new products relating to the acquired businesses;

| • |  | potential difficulties and inefficiencies in managing and operating businesses in multiple locations or operating businesses in which the combined company has either limited or no direct experience;

| • |  | potential difficulties integrating financial reporting systems;

| • |  | potential difficulties in the timely filing of required reports with the SEC; and

| • |  | potential difficulties in implementing controls, procedures and policies, including disclosure controls and procedures and internal controls over financial reporting, appropriate for a larger public company at companies that, prior to the acquisition of such companies, had lacked such controls, procedures and policies, which may result in ineffective disclosure controls and procedures or material weaknesses in internal controls over financial reporting;

| • |  | the combined company may not be able to achieve the expected synergies from an acquisition or it may take longer than expected to achieve those synergies;

| • |  | an acquisition may result in future impairment charges related to diminished fair value of businesses acquired as compared to the price Hologic or Cytyc paid for them;

32

##### Table of Contents

| • |  | an acquisition may involve restructuring operations or reductions in workforce which may result in substantial charges to the combined company’s operations;

| • |  | an acquisition may involve unexpected costs or liabilities, or the effects of purchase accounting may be different from the combined company’s expectations; and

| • |  | the acquired businesses may be adversely affected by future legislative, regulatory, or tax decisions and/or changes as well as other economic, business and/or competitive factors.

Hologic’s acquisition of AEG Elektrofotografie, which conducts its business worldwide, with headquarters in Germany and manufacturing operations in Germany and China, is also subject to the additional challenges and risks associated with volatility in the market for organic photoconductor coatings used for laser printer cartridges, and the combined company’s international operations, including those related to integration of operations across different cultures and languages, currency risk and the particular economic, legal, political and regulatory risks associated with specific countries. Failure of the combined company to realize the anticipated benefits from combining the acquired businesses could harm the combined company’s business and prospects and adversely affect the market price of the combined company’s common stock.

The market for Hologic’s direct-to-digital full-field mammography products is relatively new and may not develop as expected.

The markets for Hologic’s direct-to-digital full-field mammography products may not continue to develop as expected. There is a significant installed base of conventional screen-film mammography products in hospitals and radiological practices. The use of Hologic’s direct-to-digital mammography products in many cases would require these potential customers to either modify or replace their existing x-ray imaging equipment. Moreover, as direct-to-digital mammography products are generally more expensive than conventional screen-film mammography products, Hologic believes that a major factor in the market’s acceptance of direct-to-digital mammography products has been and will continue to be based upon the benefits of direct-to-digital technology as compared to less expensive technologies. As a result, the market for Hologic’s direct-to-digital mammography products has and will continue to be affected by published studies and reports relating to the comparative efficacy of digital mammography products. The publication of an adverse study could significantly impair the adoption of this technology and harm the combined company’s business. The implementation of digital mammography technology is also affected by the trend toward transition by the healthcare industry from conventional film archiving systems to hospital Picture Archiving and Communications Systems, known as PACS, to store x-ray images electronically. Because the benefits of Hologic’s direct-to-digital mammography technology may not be fully realized by customers until they install a PACS platform, a large potential market for these products may not develop until PACS environments are more widely used. Because the markets for these products are relatively new, it is likely that the combined company’s evaluation of the potential markets for these products will materially vary with time.

Current levels of growth in the market for endometrial ablation procedures, such as Cytyc’s NovaSure System, for the treatment of excessive menstrual bleeding may not be indicative of future growth.

Demand for newly introduced technologies or treatments can initially be exaggerated as supply increases to meet pre-existing demand. However, once the pre-existing demand is met, growth in the market may abruptly stop or significantly slow. Some of the current growth in the market for new endometrial ablation procedures may be the result of a considerable pre-existing unmet demand for products of this nature. Cytyc cannot predict when, or at what rate, this demand may stop or decline in growth. Cytyc cannot assure you that it will be successful in continuing to attract physicians and women to use the NovaSure System, or whether or not evolving trends in the treatment of excessive menstrual bleeding will favor new endometrial ablation procedures as compared to traditional approaches. If the demand for treatments like the NovaSure System were to stop abruptly or begin to decline, the combined company’s operating results and profitability could be adversely affected.

The success of Cytyc’s ThinPrep System depends upon the cost and continued market acceptance of Cytyc’s ThinPrep System products.

The success of Cytyc’s ThinPrep System depends on the continued market acceptance of its ThinPrep System and ThinPrep Imaging System, including any follow-on applications of ThinPrep technology. The laboratory cost of using the ThinPrep System and ThinPrep Imaging System for cervical cancer screening, both together and individually, is higher than that of a conventional Pap smear and, Cytyc believes, competing liquid-based slide preparation systems. Due in part to increased competitive pressures in the cytology screening market and healthcare industry to reduce costs, the combined company’s ability to continue gaining market acceptance of the ThinPrep System and follow-on products will depend on its ability to demonstrate that the higher cost of using the ThinPrep System is offset by (i) a reduction in costs often associated with conventional Pap smears or competing liquid-based slide preparation systems, such as inaccurate diagnoses and the need for repeat Pap smears, as well as (ii) the ability to conduct additional testing, such as testing for the HPV, Chlamydia trachomatis and Neisseria gonorrhea on samples collected in a ThinPrep vial of preservative. In particular, for the ThinPrep Imaging System, the combined company will need to work with healthcare providers, insurance companies and other third-party payors, and clinical laboratories to reinforce the known clinical efficacy and cost-effectiveness of the ThinPrep Imaging System.

Cytyc is dependent upon a relatively small number of large clinical laboratory customers in the United States for a significant portion of its sales of the ThinPrep System.

Cytyc is dependent upon a relatively small number of large clinical laboratory customers in the United States for a significant portion of its sales of the ThinPrep System. The business and prospects of the combined company may be harmed if the combined company is unable to increase sales to, or maintain pricing levels with Cytyc’s existing customers and establish new customers both within and outside the United States. Due in part to a trend toward consolidation of clinical laboratories in recent years and the relative size of the largest United States laboratories, it is likely that a significant portion of ThinPrep System sales will continue to be concentrated among a relatively small number of large clinical laboratories.

The combined company’s success will depend on new product development.

Each of Hologic and Cytyc has continuing research and development programs designed to develop new products and to enhance and improve its products. Hologic is expending significant resources on the development of digital x-ray imaging products, including the development of a digital mammography product to perform breast tomosynthesis, a 3-dimensional imaging technique. Cytyc is expending significant resources on continued product line enhancements. The successful development of the combined company’s products and product enhancements is subject to numerous risks, both known and unknown, including:

| • |  | unanticipated delays;

| • |  | access to capital;

| • |  | budget overruns;

| • |  | technical problems; and

| • |  | other difficulties that could result in the abandonment or substantial change in the design, development and commercialization of these new products, including, for example, changes requested by the FDA in connection with pre-market approval applications for products or 510(k) notification.

Given the uncertainties inherent with product development and introduction, there can be no assurance that any of the combined company’s product development efforts will be successful on a timely basis or within budget, if at all. The failure of the combined company to develop new products and product enhancements, such as Hologic’s digital mammography tomosynthesis product, on a timely basis or within budget could harm the combined company’s business and prospects and could adversely affect the market price of the combined company’s common stock.

The markets for and future growth of the combined company’s products and treatments may not develop as expected.

There can be no assurance that the combined company’s existing products or treatments, or the enhancement of products or treatments will be commercially successful. The successful commercialization of the combined company’s products and treatments are subject to numerous risks, both known and unknown, including:

| • |  | uncertainty of the development of a market for such product or treatment;

| • |  | trends relating to, or the introduction or existence of, competing products, technologies or alternative treatments or therapies that may be more effective, safer or easier to use than the combined company’s products, technologies, treatments or therapies;

| • |  | perceptions of the combined company’s products or treatments as compared to other products and treatments;

| • |  | recommendation and support for the use of the combined company’s products or treatments by influential customers, such as hospitals, radiological practices, breast surgeons and radiation oncologists and treatment centers;

| • |  | the availability and extent of data demonstrating the clinical efficacy of the combined company’s products or treatments;

| • |  | competition, including the presence of competing products sold by companies with longer operating histories, more recognizable names and more established distribution networks; and

| • |  | other technological developments.

Often, the development of a significant market for a product or treatment will depend upon the establishment of a reimbursement code or an advantageous reimbursement level for use of the product or treatment. Moreover, even if addressed, such reimbursement codes or levels frequently are not addressed until after a product or treatment is developed and commercially introduced, which can delay the successful commercialization of a product or treatment. If the combined company is unable to successfully commercialize and create a significant market for its products and treatments, such as Hologic’s digital mammography tomosynthesis product, due to, among other things, the lack of reimbursement codes or disadvantageous reimbursement levels for such products or treatments, the combined company’s business and prospects could be harmed and the market price of the combined company’s common stock could be adversely affected.

The combined company may not be successful in growing its international sales, which could have a material adverse effect on its business and financial condition.

The combined company cannot guarantee that it will successfully continue to develop international sales channels or capabilities that will enable it to generate significant revenue from international sales. The combined company may not be able to obtain favorable third-party reimbursements and required regulatory approvals in foreign countries. Failure to continue to increase international sales could harm the business and prospects of the combined company.

The combined company’s success depends on its ability to manage growth effectively.

The operations and facilities, including the number of employees and the geographic area of operations, of Hologic and Cytyc have grown rapidly, and the combined company’s operations and facilities are expected to continue to grow. The failure of the combined company to manage growth effectively could harm the business and prospects of the combined company. The growth of the combined company may significantly strain the combined company’s managerial, operational and financial resources and systems. To manage the combined company’s growth effectively, it is expected that the combined company will continue to implement and improve additional management and financial systems and controls, and to effectively retain, expand, train and manage its employee base.

The business of the combined company could be harmed if it infringes upon the intellectual property rights of others.

There has been substantial litigation regarding patent and other intellectual property rights in the medical device and related industries. Hologic and Cytyc have each been involved in infringement litigation, and may in the future be notified that the combined company may be infringing intellectual property rights possessed by third parties.

For example, in March 2005, Hologic was served with a complaint alleging that Hologic’s HTC™ grid infringes U.S. Patent Number 5,970,118. The plaintiff sought to preliminarily and permanently enjoin Hologic from infringing the patent, as well as damages resulting from the alleged infringement, treble damages and reasonable attorney fees, and such other and further relief as may be available. In March 2007, the court granted Hologic’s motion for summary judgment and dismissed the complaint with prejudice. The plaintiff has a right to appeal the matter after conclusion of the case as a whole.

On June 16, 2003, Cytyc filed a suit for Declaratory Judgment in United States District Court for the District of Massachusetts asking the court to determine and declare that certain of TriPath Imaging, Inc.’s patents are invalid and not infringed by Cytyc’s ThinPrep Imaging System. On June 17, 2003, TriPath announced that it had filed a lawsuit against Cytyc in the United States District Court for the Middle District of North Carolina alleging patent infringement, false advertising, defamation, intentional interference, unfair competition, and unfair and deceptive trade practices. In its complaint TriPath sought the issuance of a preliminary and permanent injunction enjoining Cytyc from infringing the asserted patents and to award unspecified damages, unspecified treble damages and attorneys’ fees, and the impounding and destruction of the alleged infringing products. As to the non-patent claims, TriPath sought unspecified damages, punitive damages and attorneys’ fees. The non-patent claims have been dismissed and the patent cases have since been consolidated into a single action. A hearing occurred on August 2, 2006 in the United States District Court for the District of Massachusetts to hear oral arguments on summary judgment motions. Rulings on these motions are still pending. A trial is expected to occur beginning late October 2007. See Annex B under “Information about Cytyc—Legal Proceedings.”

In connection with litigation or if any claims are asserted against the combined company’s intellectual property rights, the combined company may seek to enter into royalty or licensing arrangements. There is a risk in these situations that no license will be available or that a license will not be available on reasonable terms. Alternatively, the combined company may decide to litigate such claims or to design around the patented technology. These actions could be costly and would divert the efforts and attention of the combined company’s management and technical personnel. As a result, any infringement claims by third parties or claims for indemnification by customers resulting from infringement claims, whether or not proven to be true, may harm the combined company’s business and prospects.

If Hologic fails to achieve and maintain the high manufacturing standards that Hologic’s direct radiography products require, the combined company may not be successful in developing and marketing those products.

The manufacture of Hologic’s direct radiography detectors is highly complex and requires precise high quality manufacturing that is difficult to achieve. Hologic has in the past and the combined company may in the future experience difficulties in manufacturing these detectors in commercial quantities, primarily related to delays and difficulties in obtaining critical components for these detectors that meet Hologic’s high manufacturing standards. Hologic’s initial difficulties led to increased delivery lead-times and increased costs of manufacturing these products. The combined company’s failure, including the failure of its contract manufacturers, to achieve and maintain the required high manufacturing standards could result in further delays or failures in product testing or delivery, cost overruns, product recalls or withdrawals, or other problems that could harm the combined company’s business and prospects.

Interruptions, delays, shutdowns or damage at the combined company’s manufacturing facilities could harm its business.

Hologic manufactures most of its products at its manufacturing facilities in Danbury, Connecticut, Bedford, Massachusetts, Indianapolis, Indiana and Newark, Delaware. In addition, Hologic manufactures the selenium coatings used in the digital x-ray image capture radiographic systems in Germany and its selenium and organic

36

##### Table of Contents

photoconductor coatings for other uses in Germany and China. Cytyc assembles and manufactures its ThinPrep products at its facilities in Marlborough, Massachusetts and Londonderry, New Hampshire. In addition, Cytyc manufactures its NovaSure System and MammoSite System in Costa Rica. An interruption in manufacturing capabilities at any of these facilities, as a result of equipment failure or other reasons, could reduce, delay or prevent the production of the combined company’s products. The manufacturing facilities of the combined company will be subject to the risk of catastrophic loss due to unanticipated events, such as fires, earthquakes, explosions, floods or weather conditions. The combined company’s manufacturing facilities may experience plant shutdowns, strikes or other labor disruptions, or periods of reduced production as a result of equipment failures, loss of power, gray outs, delays in deliveries or extensive damage to any of its facilities, which could harm the business and prospects of the combined company. Because some of the combined company’s manufacturing operations will be located in Germany, China and Costa Rica, those manufacturing operations will also be subject to additional challenges and risks associated with international operations described below.

The uncertainty of healthcare reform could harm the combined company’s business and prospects.

In recent years, the healthcare industry has undergone significant change driven by various efforts to reduce costs, including efforts at national healthcare reform, trends toward managed care, cuts in Medicare, consolidation of healthcare distribution companies and collective purchasing arrangements by office-based healthcare practitioners. Healthcare reform proposals and medical cost containment measures in the United States and in many foreign countries could:

| • |  | limit the use of the combined company’s products;

| • |  | reduce reimbursement available for such use; or

| • |  | adversely affect the use of new therapies for which the combined company’s products may be targeted.

These reforms or cost containment measures, including the uncertainty in the medical community regarding their nature and effect, could harm the combined company’s business and prospects.

The combined company’s business could be harmed if products contain undetected errors or defects or do not meet customer specifications.

Hologic and Cytyc are continuously developing new products and improving their existing products. Newly introduced products can contain undetected errors or defects. In addition, these products may not meet their performance specifications under all conditions or for all applications. If, despite internal testing and testing by customers, any of the combined company’s products contain errors or defects or fail to meet customer specifications, then the combined company may be required to enhance or improve those products or technologies. The combined company may not be able to do so on a timely basis, if at all, and may only be able to do so at considerable expense. In addition, any significant reliability problems could result in adverse customer reaction, negative publicity or legal claims and could harm the combined company’s business and prospects.

The combined company will rely on one or only a limited number of suppliers for some key components or subassemblies for its products, which could harm the combined company’s business and prospects.

Hologic and Cytyc each rely on one or only a limited number of suppliers for some key components or subassemblies for their products. In particular, Hologic has a limited number of suppliers for the panel for its direct radiography products and AEG, one of Hologic’s subsidiaries, is Hologic’s sole source provider for Selenium coatings. In addition, Hologic has only limited sources of supply for some key components used in its mini C-arm systems and its Suros biopsy systems. Cytyc currently obtains certain key components of its products, including the proprietary filter material and microscope slides used in the ThinPrep Pap Test, radioisotopes, certain balloons and other items used in the design and manufacture of the MammoSite System and the Iotrex liquid isotope used with the GliaSite System, from single or a limited number of sources due to

37

##### Table of Contents

technology, availability, price, quality and other considerations. Additionally, the NovaSure System utilizes several components that may become obsolete or no longer be manufactured.

Obtaining alternative sources of supply of these components could involve significant delays and other costs and regulatory challenges, and may not be available to the combined company on reasonable terms, if at all. The failure of a component supplier or contract assembler to provide sufficient quantities, acceptable quality and timely components or assembly service at an acceptable price, or an interruption of supplies from such a supplier could harm the business and prospects of the combined company. Any disruption of supplies of key components could delay or reduce shipments, which could result in lost or deferred sales for the combined company.

The combined company will face intense competition from other companies and may not be able to compete successfully.

A number of companies have developed, or are expected to develop, products that compete or will compete with the combined company’s products. Some of combined company’s competitors will be large companies that may enjoy significant competitive advantages over the combined company, including:

| • |  | significantly greater name recognition;

| • |  | established distribution networks;

| • |  | additional lines of products, and the ability to offer rebates or bundle products to offer discounts or incentives to gain competitive advantage;

| • |  | more extensive research, development, sales, marketing and manufacturing capabilities; and

| • |  | better positioning to continue to improve their technology in order to compete in an evolving industry.

The markets in which the combined company will sell in are intensely competitive, subject to rapid change and may be significantly affected by new product introductions and other market activities of industry participants. Other companies may develop products that are superior to or less expensive, or both, than the combined company’s products. Improvements in existing competitive products or the introductions of new competitive products may reduce the combined company’s ability to compete for sales, particularly if those competitive products demonstrate better safety or effectiveness, clinical results, ease of use or lower costs.

If the combined company is unable to compete effectively against existing and future competitors and existing and future alternative treatments, the business and prospects of the combined company could be harmed.

The combined company’s success will depend upon its ability to adapt to rapid changes in technology and customer requirements.

The markets for Hologic’s and Cytyc’s products have been characterized by rapid technological change, frequent product introductions and evolving customer requirements. These trends will likely continue into the foreseeable future. The combined company’s success will depend, in part, upon its ability to enhance the existing products of Hologic and Cytyc, successfully develop new products that meet increasing customer requirements and gain market acceptance. If the combined company fails to do so its products may be rendered obsolete or uncompetitive by new industry standards or changing technology.

The combined company’s results of operations will be subject to significant quarterly variation and seasonal fluctuation.

Hologic’s and Cytyc’s results of operations have been and may continue to be subject to significant quarterly variation. The combined company’s results for a particular quarter may also vary due to a number of factors, including:

| • |  | the overall state of healthcare and cost containment efforts;

38

##### Table of Contents

| • |  | the timing and level of reimbursement for the combined company’s products domestically and internationally;

| • |  | the development status and demand for the combined company’s products;

| • |  | the development status and demand for therapies to treat breast cancer and osteoporosis;

| • |  | economic conditions in the combined company’s markets;

| • |  | foreign exchange rates;

| • |  | the timing of orders;

| • |  | the timing of expenditures in anticipation of future sales;

| • |  | the mix of products the combined company sells;

| • |  | the introduction of new products and product enhancements by the combined company or its competitors;

| • |  | pricing and other competitive conditions; and

| • |  | unanticipated expenses.

Customers may also cancel or reschedule shipments. Production difficulties could also delay shipments. Any of these factors also could harm the combined company’s business and prospects.

The combined company’s delay or inability to obtain any necessary United States or foreign regulatory clearances or approvals for its products could harm the combined company’s business and prospects.

Hologic’s and Cytyc’s products are, and the combined company’s products will be, medical devices that are the subject of a high level of regulatory oversight. The combined company’s delay or inability to obtain any necessary United States or foreign regulatory clearances or approvals for its products, such as Hologic’s digital mammography tomosynthesis product, could harm its business and prospects and could adversely affect the market price of the combined company’s common stock. The process of obtaining clearances and approvals can be costly and time-consuming. There is a risk that any approvals or clearances, once obtained, may be withdrawn or modified.

Medical devices cannot be marketed in the United States without clearance or approval by the FDA. Any modifications to a device that has received a pre-market approval that affect its safety or effectiveness require a pre-market approval supplement or possibly a separate pre-market approval, either of which is likely to be time-consuming, expensive and uncertain to obtain. If the FDA requires the combined company to seek one or more pre-market approval supplements or new pre-market approvals for any modification to a previously approved device, the combined company may be required to cease marketing or to recall the modified device until it obtains approval, and the combined company may be subject to significant criminal and/or civic sanctions, including but not limited to, regulatory fines or penalties.

Medical devices sold in the United States must also be manufactured in compliance with FDA Good Manufacturing Practices, which regulate the design, manufacture, packing, storage and installation of medical devices. Moreover, medical devices are required to comply with FDA regulations relating to investigational research and labeling. States may also regulate the manufacture, sale and use of medical devices, particularly those that employ x-ray technology. The combined company’s products will also be subject to approval and regulation by foreign regulatory and safety agencies.

Recent proposed changes to reclassify full-field digital mammography to permit 510(k) clearance could increase competition for Hologic’s digital mammography products.

On May 23, 2006 the FDA Radiological Devices Panel recommended the reclassification of full-field digital mammography systems from Class III to Class II devices. The FDA has not taken any additional steps to act on

39

##### Table of Contents

the panel’s recommendation. If the FDA implements the panel’s recommendation, the reclassification would allow full-field digital mammography systems to be cleared for commercialization through the 510(k) process, which is less rigorous than the present pre-market approval process. If and when implemented, the reclassification for full-field digital mammography systems from Class III to Class II devices may lower barriers of entry into the digital mammography market, may result in more competitors entering the United States market and could harm sales of Hologic’s digital mammography systems.

The combined company’s products may be subject to recalls even after receiving FDA clearance or approval, which could harm the combined company’s business and prospects.

The FDA and similar governmental bodies in other countries have the authority to require the recall of medical products in the event of material deficiencies or defects in design or manufacture. A government mandated or voluntary recall by the combined company could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling. Any recall could harm the reputation of the combined company’s products and adversely affect the combined company’s business and prospects.

Some of the combined company’s activities may subject the combined company to risks under federal and state laws prohibiting “kickbacks” and false or fraudulent claims.

Hologic and Cytyc are, and the combined company will be, subject to the provisions of a federal law commonly known as the Medicare/Medicaid anti-kickback law, and several similar state laws, which prohibit payments intended to induce physicians or others either to refer patients or to acquire or arrange for or recommend the acquisition of healthcare products or services. While the federal law applies only to referrals, products or services for which payment may be made by a federal healthcare program, state laws often apply regardless of whether federal funds may be involved. These laws constrain the sales, marketing and other promotional activities of manufacturers of medical devices by limiting the kinds of financial arrangements, including sales programs, with hospitals, physicians, laboratories and other potential purchasers of medical devices. Other federal and state laws generally prohibit individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent, or are for items or services that were not provided as claimed. Anti-kickback and false claims laws prescribe civil and criminal penalties (including fines) for noncompliance that can be substantial. While Hologic and Cytyc continually strive, and the combined company will strive, to comply with these complex requirements, interpretations of the applicability of these laws to marketing practices is ever evolving and even an unsuccessful challenge could cause adverse publicity and be costly to respond to, and thus could harm the business and prospects of the combined company.

The combined company is subject to the risk of product liability claims relating to its products.

Hologic’s and Cytyc’s businesses involve, and the combined company’s business will involve, the risk of product liability and other claims inherent to the medical device business. If even one of the combined company’s products is found to have caused or contributed to injuries or deaths, the combined company could be held liable for substantial damages. Hologic and Cytyc maintain, and the combined company will maintain, product liability insurance subject to deductibles and exclusions. There is a risk that the insurance coverage will not be sufficient to protect the combined company from product and other liability claims, or that product liability insurance will not be available to the combined company at a reasonable cost, if at all. An under-insured or uninsured claim could harm the business and prospects of the combined company. In addition, claims could adversely affect the reputation of the related product, which could damage that product’s competitive position in the market.

The sale and use of one of the combined company’s diagnostic products could also lead to the filing of product liability claims if someone were to allege that one of the combined company’s products contained a design or manufacturing defect that resulted in the failure to detect a disorder for which it was being used to

40

##### Table of Contents

screen or caused injuries to a patient. Any product liability claim brought against the combined company, with or without merit, could result in the increase of the combined company’s product liability insurance rates or the inability to secure additional coverage in the future. Also, even a meritless or unsuccessful product liability claim could be time consuming and expensive to defend, which could result in a diversion of management’s attention from the combined company’s business and could adversely affect the perceived safety and efficacy of the combined company’s products, and could harm the business and prospects of the combined company.

The combined company will use hazardous materials and products.

Hologic’s and Cytyc’s research and development involves, and the combined company’s research and development will involve, the controlled use of hazardous materials, such as toxic and carcinogenic chemicals and various radioactive compounds. Although Hologic and Cytyc believe that their safety procedures for handling and disposing of such materials comply with the standards prescribed by federal, state and local regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. In the event of this type of accident, the combined company could be held liable for any resulting damages, and any such liability could be extensive. Hologic and Cytyc are also subject, and the combined company will be subject, to substantial regulation relating to occupational health and safety, environmental protection, hazardous substance control, and waste management and disposal. The failure to comply with such regulations could subject the combined company to, among other things, fines and criminal liability.

Fluctuations in the exchange rates of European currencies and the other foreign currencies in which the combined company will conduct its business, in relation to the U.S. dollar, could harm the combined company’s business and prospects.

Hologic maintains a sales and service office in Belgium, and Hologic’s AEG Elektrofotografie subsidiary conducts its business worldwide, with headquarters in Germany and manufacturing operations in Germany and China. The expenses of these offices are denominated in local currencies, and Hologic’s foreign sales may be denominated in local currencies, the Euro or U.S. dollars.

Cytyc’s business outside the United States is conducted primarily in local currencies, except at its Costa Rica subsidiary, where the majority of business is conducted in U.S. dollars.

Fluctuations in foreign currency exchange rates could affect the combined company’s cost of goods and operating margins and could result in exchange losses. In addition, currency devaluation can result in a loss to the combined company if it holds deposits of that currency. Hologic has hedged its foreign currency exposure by borrowing funds in local European currencies to pay the expenses of its foreign offices. In addition, Hologic’s recently acquired AEG operation has engaged in hedging activities, such as currency swaps, to hedge its foreign currency exposure. There is a risk that any hedging activities will not be successful in mitigating the combined company’s foreign exchange risk exposure.

The combined company’s international operations expose the combined company to additional operational challenges that it might not otherwise face.

Hologic and Cytyc are, and the combined company will be, subject to a number of additional risks and expenses due to their international operations. Any of these risks or expenses could have a material adverse effect on the combined company’s operating results. These risks and expenses include:

| • |  | difficulties in staffing and managing operations in multiple locations as a result of, among other things, distance, language and cultural differences;

| • |  | protectionist laws and business practices that favor local companies;

| • |  | greater difficulties in trade accounts receivable collection;

41

##### Table of Contents

| • |  | difficulties and expenses related to implementing internal controls over financial reporting and disclosure controls and procedures;

| • |  | expenses associated with customizing products for clients in foreign countries;

| • |  | possible adverse tax consequences;

| • |  | governmental currency controls;

| • |  | multiple, conflicting and changing government laws and regulations (including, among other things, antitrust and tax requirements, international trade regulations and the Foreign Corrupt Practices Act);

| • |  | reduced protection for intellectual property rights in some countries;

| • |  | political and economic changes and disruptions;

| • |  | export/import controls; and

| • |  | tariff regulations.

The business of the combined company could be harmed if it is unable to protect its proprietary technology.

Hologic and Cytyc have relied, and the combined company will rely, primarily on a combination of trade secrets, patents, copyright and trademark laws and confidentiality procedures to protect its products and technology. Despite these precautions, unauthorized third parties may infringe, copy or reverse engineer portions of the combined company’s technology. Hologic and Cytyc do not know if current or future patent applications will be issued with the scope of the claims sought, if at all, or whether any patents issued will be challenged or invalidated. In addition, Hologic and Cytyc have each obtained or applied for corresponding patents and patent applications in several foreign countries for some of its patents and patent applications. There is a risk that these patent applications will not be granted or that the patent or patent application will not provide significant protection for Hologic’s, Cytyc’s or the combined company’s products and technology. Competitors of the combined company may independently develop similar technology that Hologic’s, Cytyc’s or the combined company’s patents do not cover. In addition, because patent applications in the United States are not generally publicly disclosed until eighteen months after the application is filed, applications may have been filed by third parties which relate to Hologic’s, Cytyc’s or the combined company’s technology. Moreover, there is a risk that foreign intellectual property laws will not protect the intellectual property rights of the combined company to the same extent as United States intellectual property laws. In the absence of significant patent protection, the combined company may be vulnerable to competitors who attempt to copy its products, processes or technology.

The combined company’s future success will depend on the continued services of key personnel.

The loss of any key personnel of the combined company, particularly key research and development personnel, could harm the combined company’s business and prospects and could impede the achievement of the combined company’s research and development, operational or strategic objectives. The combined company’s success will also depend upon its ability to attract and retain other qualified managerial and technical personnel. Competition for such personnel, particularly software engineers and other technical personnel, is intense. The combined company may not be able to attract and retain personnel necessary for the development of its business.

The combined company’s business may be harmed by acquisitions it completes in the future.

The combined company’s identification of suitable acquisition candidates involves risks inherent in assessing the values, strengths, weaknesses, risks and profitability of acquisition candidates, including the effects of the possible acquisition on its business, diversion of its management’s attention and risks and costs associated with unanticipated problems or latent liabilities, such as litigation, investigations or inquiries in connection with acquisitions that it completes. If the combined company is successful in pursuing future acquisitions, it will be required to expend significant funds, incur additional debt or issue additional securities, which may negatively

42

##### Table of Contents

affect its results of operations and be dilutive to the combined company’s stockholders. If the combined company spends significant funds or incurs additional debt, its ability to obtain financing for working capital or other purposes could decline, and it may be more vulnerable to economic downturns and competitive pressures. Neither Hologic nor Cytyc can guarantee that the combined company will be able to finance additional acquisitions or that the combined company will realize any anticipated benefits from acquisitions that it completes. Should the combined company acquire another business, the process of integrating acquired operations into its existing operations may result in unforeseen operating difficulties and may require significant financial resources that would otherwise be available for the ongoing development or expansion of its existing business.

The combined company’s failure to manage current or future alliances or joint ventures effectively may harm the combined company’s business and prospects.

Hologic and Cytyc have entered into, and the combined company may enter into, alliances, joint ventures or other business relationships. Alliances with certain partner or companies could make it more difficult for the combined company to enter into advantageous business transactions or relationships with others. Moreover, the combined company may not be able to:

| • |  | identify appropriate candidates for alliances or joint ventures;

| • |  | assure that any alliance or joint venture candidate will provide the combined company with the support anticipated;

| • |  | successfully negotiate an alliance or joint venture on terms that are advantageous to the combined company; or

| • |  | successfully manage any alliance or joint venture.

Furthermore, any alliance or joint venture may divert management time and resources. Entering into a disadvantageous alliance or joint venture, failing to manage an alliance or joint venture effectively, or failing to comply with obligations in connection therewith, could harm the combined company’s business and prospects.

The combined company will be exposed to potential risks and it will continue to incur significant costs as a result of the internal control testing and evaluation process mandated by Section 404 of the Sarbanes-Oxley Act of 2002.

Hologic assessed the effectiveness of its internal control over financial reporting as of September 30, 2006 and assessed all deficiencies on both an individual basis and in combination to determine if, when aggregated, they constitute a material weakness. As a result of this evaluation, no material weaknesses were identified.

Cytyc assessed the effectiveness of its internal control over financial reporting as of December 31, 2006, and determined that it did not implement controls necessary to provide reasonable assurance that the accounting for certain stock option exercise activity that occurred during the period from 1996 through 2002 was properly recorded in its financial statements included in its annual report on Form 10-K for the year ended December 31, 2006, in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees. To remedy this material weakness Cytyc enhanced its policies surrounding consultations on complex technical accounting matters to include third-party subject matter experts, including experts with additional specific knowledge of the accounting for the types of stock option exercise activity described above, to assist Cytyc in reaching a conclusion regarding the accounting for this stock option exercise activity in accordance with Accounting Principles Board Opinion No. 25. This remediation effort was tested and found to be effective as of the date of the filing of Cytyc’s amendment to its annual report on Form 10-K for the year ended December 31, 2006.

##### Table of Contents

Following the completion of the merger, the combined company expects to continue to incur significant costs, including increased accounting fees and increased staffing levels, in order to maintain compliance with Section 404 of the Sarbanes-Oxley Act. The combined company will continue to monitor controls for any weaknesses or deficiencies. No evaluation can provide complete assurance that the combined company’s internal controls will detect or uncover all failures of persons within the company to disclose material information otherwise required to be reported. The effectiveness of the combined company’s controls and procedures could also be limited by simple errors or faulty judgments. In addition, as the combined company continues to expand globally, the challenges involved in implementing appropriate internal controls will increase and will require that the combined company continues to improve its internal controls over financial reporting.

Hologic’s assessment of internal controls in fiscal 2006 did not include Hologic’s recently acquired entities of AEG, R2 and Suros. In 2007, Cytyc acquired Adeza Biomedical Corporation and Adiana, Inc. Hologic’s assessment of internal control over financial reporting is expected to include AEG, R2 and Suros in fiscal 2007, and is expected to include Cytyc, Adeza Biomedical Corporation and Adiana Inc. in fiscal 2008. The combined company expects to face additional challenges in implementing the required processes, procedures and controls as a result of the merger and other acquired operations. For example, Hologic’s recently acquired companies do not have disclosure controls and procedures or internal control over financial reporting that are as thorough or effective as those required by securities law applicable to public companies in the United States. Although the combined company intends to devote substantial time and incur substantial costs, as necessary, to ensure ongoing compliance, the combined company cannot be certain that it will be successful in complying with Section 404 of the Sarbanes-Oxley Act.

In the future, if the combined company fails to complete the Sarbanes-Oxley 404 evaluation in a timely manner, or if its independent registered public accounting firm cannot attest in a timely manner to the combined company’s evaluation, the combined company could be subject to regulatory scrutiny and a loss of public confidence in the combined company’s internal controls which could adversely impact the market price of Hologic common stock. The combined company or its independent registered public accounting firm may identify material weaknesses in internal controls over financial reporting which may result in a loss of public confidence in the combined company’s internal controls and adversely impact the market price of Hologic common stock. In addition, any failure to implement required, new or improved controls, or difficulties encountered in their implementation, could harm the combined company’s operating results or cause the combined company to fail to meet its reporting obligations.

RISKS RELATED TO HOLOGIC COMMON STOCK

Provisions in Hologic’s charter and bylaws and its stockholder rights plan may have the effect of discouraging advantageous offers for Hologic’s business or common stock and limit the price that investors might be willing to pay in the future for shares of Hologic common stock.

Hologic’s charter, bylaws and the provisions of the DGCL include provisions that may have the effect of discouraging or preventing a change in control. In addition, Hologic has a stockholder rights plan that may have the effect of discouraging or preventing a change in control. These provisions could limit the price that Hologic stockholders might receive in the future for shares of Hologic common stock.

Hologic’s stock price is volatile.

The market price of Hologic common stock has been, and may continue to be, highly volatile. Hologic believes that a variety of factors could cause the price of its common stock to fluctuate, perhaps substantially, including:

| • |  | announcements and rumors of developments related to Hologic’s business, including changes in reimbursement rates, proposed and completed acquisitions, or the industry in which Hologic competes;

##### Table of Contents

| • |  | quarterly fluctuations in Hologic’s actual or anticipated operating results and order levels;

| • |  | general conditions in the worldwide economy;

| • |  | announcements of technological innovations;

| • |  | new products or product enhancements by Hologic or its competitors;

| • |  | developments in patents or other intellectual property rights and litigation; and

| • |  | developments in relationships with Hologic’s customers and suppliers.

In addition, in recent years the stock market in general and the markets for shares of “high-tech” companies, have experienced extreme price fluctuations which have often been unrelated to the operating performance of affected companies. Any such fluctuations in the future could adversely affect the market price of Hologic’s common stock, and the market price of Hologic common stock may decline.

THE MERGER

The following discussion contains important information relating to the merger. You are urged to read this discussion together with the merger agreement and related documents attached as annexes to this joint proxy statement/prospectus before voting on the merger agreement and the merger or the amendment to Hologic’s charter and issuance of Hologic common stock in the merger.

Structure of the Merger

The merger agreement provides for the merger of Cytyc with and into Nor’easter Corp., a wholly owned subsidiary of Hologic that was formed for the purpose of the merger, with Nor’easter Corp. surviving the merger. At the effective time of the merger, the surviving entity will remain a wholly owned subsidiary of Hologic, and Nor’easter Corp. will be renamed “Cytyc Corporation.” The merger will become effective when Nor’easter Corp. and Cytyc file a certificate of merger with the Secretary of State of the State of Delaware (or at such later time as Hologic and Cytyc mutually agree and specify in the certificate of merger). The time the merger becomes effective is referred to as the effective time of the merger.

Merger Consideration

At the effective time of the merger, each issued and outstanding share of Cytyc common stock will be converted into the right to receive 0.52 of a share, referred to as the exchange ratio, of Hologic common stock, referred to as the stock merger consideration, and $16.50 in cash without interest, referred to as the cash merger consideration. The stock merger consideration, together with the cash merger consideration and any cash received in lieu of fractional shares, is referred to as the merger consideration. Cytyc stockholders will receive cash in lieu of any fractional shares of Hologic common stock that would have otherwise been received in the merger. See “The Merger Agreement—Fractional Shares” beginning on page 117.

Hologic and Cytyc expect that, upon completion of the merger, assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024, the Cytyc stockholders immediately prior to the merger will own approximately 55% of the outstanding common stock of the combined company, and the Hologic stockholders immediately prior to the merger will own approximately 45% of the outstanding common stock of the combined company.

Background of the Merger

Each of Hologic’s and Cytyc’s board of directors has from time to time in recent years engaged with senior management in strategic reviews and considered ways to enhance its company’s performance and prospects in light of the business and economic environment. For each company, these reviews have included consideration of potential transactions with third parties that would further its strategic objectives and the potential benefits and risks of those transactions. With respect to both Hologic and Cytyc, these strategic reviews have on several occasions related to informal exploratory discussions regarding potential strategic transactions, including possible business combinations with each other and other companies in the life sciences/healthcare industry.

Given the relative close proximity and similar business focus of Hologic and Cytyc, both being Massachusetts-based public companies focused on women’s health, the companies have been familiar with each other’s businesses for a number of years.

Approximately three years ago, Thomas Umbel, senior vice president of business development of Hologic contacted a business development representative of Cytyc, to discuss whether the parties would be interested in further exploring potential business opportunities. Nothing materialized from these conversations at that time.

Following review and discussion among the members of the Hologic board of directors, including consideration of the factors described under “— Hologic Reasons for the Merger” beginning on page 54, the Hologic board of directors unanimously determined that the transactions contemplated by the merger agreement, including the amendment to Hologic’s charter to increase the number of authorized shares of Hologic common stock and the issuance of shares of Hologic common stock in the merger, are advisable and in the best interests of Hologic and its stockholders, and the Hologic directors voted unanimously to approve the merger and the merger agreement, resolved to recommend these and related matters to Hologic’s stockholders for their approval and authorized Hologic’s management to take certain actions to bring the transaction negotiations to a successful conclusion, including, without limitation, the execution and delivery of the financing commitment and transactions contemplated thereby.

At the conclusion of each of their respective presentations and responses to questions from the board of directors regarding their presentations, each of Morgan Stanley and JPMorgan rendered to the Cytyc board of directors its oral opinion (subsequently confirmed in writing) to the effect that, as of the date of its opinion, and subject to and based on the factors, assumptions, limitations and qualifications set forth in its opinion, the merger consideration to be received by the holders of Cytyc common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. See “—Opinions of Financial Advisors to the Cytyc Board of Directors.” Members of senior management and representatives of Hogan & Hartson then provided the board of directors an overview of the due diligence review conducted with respect to Hologic by representatives of Cytyc, financial and accounting advisors, and Hogan & Hartson, and discussed the results of such review. Representatives of Hogan & Hartson then summarized the terms of the merger agreement with Hologic and related documents, including those areas that had been finalized in the past several days, and also discussed fiduciary duties of the Cytyc board of directors under the circumstances and the proposed amendment to the Cytyc stockholder rights agreement. Following these discussions, and further review and discussion among the members of the Cytyc board of directors, the Cytyc board of directors unanimously determined that the transactions contemplated by the merger agreement and the merger are advisable and fair to and in the best interests of Cytyc and its stockholders, and the Cytyc directors voted unanimously to approve the merger and to approve and adopt the merger agreement and the transactions contemplated thereby, including the merger.

Following the approvals of the boards of directors of each of Hologic and Cytyc, both companies executed the merger agreement and later that day issued a joint press release on May 20, 2007 announcing the transaction.

Hologic Reasons for the Merger

In reaching its decision to approve the merger agreement and recommend approval of an amendment to the Hologic charter to increase the number of authorized shares of common stock and the issuance of Hologic common stock in the merger, the Hologic board of directors consulted with Hologic’s management, as well as with its legal and financial advisors, and considered a number of factors, including the following factors which the Hologic board of directors viewed as generally supporting its decision to approve the merger and the merger agreement and recommend that Hologic stockholders vote “FOR” the proposal to amend the Hologic charter to increase the number of authorized shares of Hologic common stock and “FOR” the proposal to issue shares of Hologic common stock in the merger.

Strategic Considerations. Hologic’s board of directors considered a number of factors pertaining to the strategic rationale for the merger as supporting its decision to approve the merger, including the following:

| • |  | the combined company will provide Hologic with a stronger financial base and a more diversified and balanced product portfolio while maintaining Hologic’s focus on women’s health;

| • |  | the likelihood of the enhancement of the strategic position of the combined company, which combines Hologic’s and Cytyc’s complementary businesses, and creates a broader company with enhanced operational and financial flexibility and increased opportunities for growth;

| • |  | the combined company’s complementary products and technologies position the combined company to offer a comprehensive product portfolio that addresses many screening and treatment needs for women. This product portfolio will enable the combined company to provide integrated solutions in screening, diagnostics and therapeutics for women’s health, including breast cancer, cervical cancer, menorrhagia, pre-natal health, osteoporosis, endometriosis and permanent contraception;

| • |  | the combined company will be able to offer an expanded product portfolio with over 90% of its total revenue from products that have leading market shares in the United States;

##### Table of Contents

| • |  | the combined company will have a comprehensive sales and service organization exclusively focused on women’s health in the diagnostic and medical technology industry in the United States, which is expected to significantly increase the combined company’s presence in hospitals, private practices and healthcare organizations;

| • |  | the combined company’s integrated product offering and broader channel coverage should provide significant cross-selling opportunities across the organization, with increasing penetration of key customer segments, such as OB/GYNs and breast cancer treatment specialists;

| • |  | the significantly greater scale and scope of the combined company’s operations is expected to better enable the combined company to take advantage of growth opportunities and creates a strong platform for further expanding operations through product development and complementary strategic transactions;

| • |  | the complementary nature of the businesses, the relative close proximity of the two companies and the strong executive teams with proven records of successfully executing strategic transactions, are expected to facilitate an efficient integration of the two companies;

| • |  | the combined company’s operations are expected to result in improved margins for Hologic;

| • |  | the combination of the cross-selling opportunities, expanded international reach, and the penetration of new and existing markets are expected to enhance revenue growth;

| • |  | the transaction is expected to generate annual cost savings from the enhanced efficiency of sales and marketing efforts, increased purchasing scale, sourcing and logistics efficiencies, and shared administrative services;

| • |  | the transaction is expected to be accretive to Hologic’s adjusted earnings per share in the first year after the transaction closes and significantly accretive thereafter; and

| • |  | the transaction is expected to enable the combined company to generate significant cash flows, which should enable the combined company to rapidly repay indebtedness incurred in connection with the transaction and reduce the leverage of the combined company resulting from the transaction.

Other Factors Considered by the Hologic Board of Directors. In addition to considering the factors described above, the Hologic board of directors considered the following additional factors, all of which it viewed as supporting its decision to approve the merger:

| • |  | the business, operations, financial condition, earnings and prospects of each of Cytyc, Hologic and the combined company;

| • |  | current and historical prices and trading information with respect to each of Cytyc’s and Hologic’s common stock, which assisted the Hologic board of directors in its conclusion that the merger was fairly priced;

| • |  | the fact that the merger consideration represented a premium to Cytyc stockholders of approximately 33% based on the closing prices of each company’s stock on the Nasdaq Global Select Market on May 18, 2007, the last trading day before the merger was publicly announced, and that the exchange ratio and cash merger consideration is fixed, which the Hologic board believed was consistent with market practice for mergers of this type and with the strategic purpose of the merger;

| • |  | the expected qualification of the merger as a reorganization under Section 368(a) of the Code, as described in the section entitled “Material United States Federal Income Tax Consequences of the Merger”;

| • |  | the current and prospective competitive climate in the industries in which Hologic and Cytyc operate, including the potential for consolidation, and the alternatives reasonably available to Hologic if it did not pursue the merger;

55

##### Table of Contents

| • |  | the expected benefits to customers and suppliers of Hologic and Cytyc, and the opportunities for the employees of the combined company;

| • |  | the belief that the terms and conditions of the merger agreement are reasonable, including:

| • |  | the fact that the representations and warranties and covenants are generally reciprocal;

| • |  | the fact that the conditions to closing are limited;

| • |  | the governance agreements with respect to the combined company post-merger, as further described under “—Board of Directors and Management of Hologic Following the Merger; Headquarters,” including the fact that (i) Mr. John W. Cumming will serve as chief executive officer of the combined company; (ii) the Hologic board of directors will consist of six continuing Hologic directors and five continuing Cytyc directors; (iii) the audit, nominating and corporate governance and corporate development committees will consist of an odd number of directors, with one more continuing Hologic director than continuing Cytyc directors and each such committee will be chaired by a Hologic director, and the compensation committee will consist of an even number of continuing Hologic directors and continuing Cytyc directors and such committee will be chaired by a continuing Cytyc director; and (iv) the principal executive offices of the combined company will continue to be located in Bedford, Massachusetts;

| • |  | the fact that Hologic is permitted to provide material non-public information to and engage in negotiations with a third party that makes an acquisition proposal that is or is reasonably likely to lead to a superior proposal (as described in “The Merger Agreement—Certain Covenants—No Solicitation” beginning on page 121), on the terms and subject to the conditions of the merger agreement;

| • |  | the ability of Hologic, under certain circumstances, to terminate the merger agreement in order to enter into an alternative transaction that is deemed by the Hologic board of directors to be a superior proposal;

| • |  | the fact that the merger agreement permits the Hologic board of directors, under certain circumstances, to change its recommendation with respect to the merger in response to a material development or change in circumstances occurring or arising after the date of execution of the merger agreement that was not known to the Hologic board of directors as of, or prior to, the date of execution of the merger agreement, provided that the change or development is not, and does not result from, a change in the market price of the common stock of Cytyc primarily as a result of the announcement of the merger agreement and the transactions contemplated thereby;

| • |  | the circumstances under which the termination fees are payable by Hologic or Cytyc under the merger agreement and the view of the Hologic board of directors that these provisions should not preclude a bona fide alternative proposal involving Hologic;

| • |  | the fact that the termination fee provisions are the product of negotiations; and

| • |  | the fact that the size of the termination fees are reasonable in light of the size and benefits of the merger;

| • |  | the waivers executed by Messrs. Cumming, Cascella and Muir conditionally waiving certain change of control payments, the retention agreement to be entered into with Mr. Cascella, and the change of control agreements, retention and severance agreements and other similar retention arrangements to be offered to key employees of Cytyc should assist the combined company in retaining key employees;

| • |  | the fact that Hologic secured fully committed debt financing in the amount of approximately $2.55 billion for the cash portion of the merger consideration, the repayment of existing debt and the expenses associated with the transaction and continued operations of the combined company;

| • |  | the terms and conditions of the financing commitment letter, including the likelihood of completing the financing contemplated by the commitment letter on the anticipated schedule without significant risk;

##### Table of Contents

| • |  | the financial analyses and presentations of each of Goldman Sachs and Jefferies, and their respective opinions, dated May 20, 2007, to the effect that, as of that date and based upon and subject to the assumptions, procedures, factors, limitations and qualifications set forth in their respective opinions, the merger consideration to be paid for each outstanding share of Cytyc common stock, taken in the aggregate, to be paid pursuant to the merger agreement, was fair, from a financial point of view, to Hologic. See “—Opinions of Financial Advisors to the Hologic Board of Directors” beginning on page 61; and

| • |  | the anticipated market capitalization, earnings and adjusted earnings per share and capital structure of the combined company.

The Hologic board of directors weighed these advantages and opportunities against a number of other factors identified in its deliberations weighing negatively against the merger, including:

| • |  | the possibility that the merger might not be completed or that completion might be delayed or subject to conditions that may be imposed by governmental authorities;

| • |  | the challenges inherent in the combination of two businesses of the size and scope of Hologic and Cytyc and the possible diversion of management’s attention for an extended period of time;

| • |  | the risk that the combined company might not retain key employees despite its best efforts;

| • |  | the risk of not capturing all the anticipated cost savings and operational synergies between Hologic and Cytyc and the risk that other anticipated benefits might not be realized;

| • |  | regulatory and litigation risks associated with the transaction or with the combination of the two companies;

| • |  | the fees and expenses associated with completing the merger and retaining key personnel;

| • |  | risks associated with the incurrence of significant indebtedness to complete the merger, such as the increased leverage of the combined company and restrictions on operations of the combined company following the completion of the merger;

| • |  | the fact that the stockholders of Hologic immediately prior to the merger will own approximately 45% of the combined company immediately following the merger (assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024);

| • |  | the fact that the merger is expected to have a dilutive effect on earnings per share of Hologic calculated in accordance with U.S. GAAP;

| • |  | the fact that Hologic expects to incur additional charges related to write-offs in connection with in-process research and development;

| • |  | the fact that upon termination of the merger agreement under specified circumstances, Hologic may be required to pay Cytyc a termination fee of either $33 million or $100 million depending on the termination event and this termination fee may discourage other parties that may otherwise have an interest in a business combination with, or an acquisition of, Hologic; and

| • |  | the other risks of the type and nature described under “Risk Factors”, and the matters described under “Cautionary Statement Regarding Forward-Looking Statements.”

In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Hologic board of directors did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination (i) to approve the merger agreement and the transactions contemplated thereby, and (ii) to recommend that Hologic stockholders vote “FOR” the proposal to amend the Hologic charter to increase the number of authorized shares of Hologic common stock and “FOR” the proposal to issue shares of Hologic common stock in

##### Table of Contents

the merger. In addition, individual members of the Hologic board of directors may have given differing weights to different factors. The Hologic board of directors conducted an overall analysis of the factors described above, including through discussions with, and questioning of, Hologic’s management and outside legal counsel and financial advisors.

In considering the recommendation of the Hologic board of directors with respect to the proposal to amend the Hologic charter to increase the authorized shares of common stock and issue shares of Hologic common stock in the merger, you should be aware that certain Hologic directors and officers have arrangements that may cause them to have interests in the transaction that are different from, or are in addition to, the interests of Hologic stockholders generally. See “—Interests of Hologic Executive Officers and Directors in the Merger” beginning on page 74.

Hologic’s board of directors considered all these factors together and, on the whole, thought them to be favorable to and to support its determination to recommend approval by Hologic stockholders of the proposals necessary to complete the merger.

Recommendation of the Hologic Board of Directors

At its May 19, 2007 meeting, after due consideration with members of Hologic’s senior management and Hologic’s outside legal counsel and financial advisors, the Hologic board of directors unanimously determined that the merger agreement, and the transactions contemplated by the merger agreement, including the amendment to the Hologic charter to increase the number of authorized shares of common stock and the issuance of Hologic common stock in the merger, are advisable to and in the best interests of Hologic and its stockholders. Accordingly, the Hologic board of directors unanimously recommends to its stockholders that they vote “FOR” the proposal to amend the Hologic charter to increase the number of authorized shares of Hologic common stock, “FOR” the proposal to issue shares of Hologic common stock in the merger, “FOR” the approval of the Hologic, Inc. Senior Executive Short-Term Plan, “FOR” the approval of the amendment to Hologic’s Seconded Amended and Restated 1999 Equity Incentive Plan and “FOR” the adjournment of the special meeting, including, if necessary, to solicit additional proxies in favor of any of the foregoing proposals.

Financing of the Merger

At the time Hologic signed the merger agreement, it entered into a commitment letter with Goldman Sachs Credit Partners L.P., dated as of May 20, 2007. The commitment letter was amended and restated on June 26, 2007 to include Banc of America Securities LLC, Bank of America, N.A., Banc of America Bridge LLC, Citigroup Global Markets Inc., JPMorgan Chase Bank, N.A. and J.P. Morgan Securities Inc. as additional arrangers of the financing. These arrangers, together with Goldman Sachs Credit Partners L.P., are referred to as the arrangers. Under the amended and restated commitment letter, referred to as the commitment letter, the arrangers have agreed to provide senior secured financing in an aggregate principal amount of up to $2.55 billion to Hologic at or about the closing date of the merger. Hologic will use the proceeds of new senior secured credit facilities together with the combined company’s available cash:

| • |  | to pay the cash consideration of the merger totaling approximately $2.05 billion;

| • |  | to repay in full all borrowings outstanding, if any, and terminate all commitments under Cytyc’s existing first lien senior secured credit facility;

| • |  | to repay in full all borrowings outstanding, if any, and terminate all commitments under Hologic’s existing senior secured revolving credit facility;

| • |  | to pay fees, commissions and expenses, estimated to be approximately $100 million, incurred by the combined company in connection with the merger transaction; and

| • |  | for certain permitted acquisitions, working capital and general corporate purposes.

58

##### Table of Contents

Hologic may also use the proceeds of the new senior secured credit facility, together with the combined company’s available cash, to redeem all of Cytyc’s outstanding $250 million 2.25% Senior Convertible Notes due 2024, which have not been converted into Cytyc common stock in connection with the merger and which have been delivered to Cytyc or Hologic for redemption.

The following is a summary of the material provisions of the proposed new credit facilities as set forth in the commitment letter. The terms, conditions and covenants of the new credit facilities are subject to the negotiation, execution and delivery of definitive credit documents. Accordingly, some of the actual terms, conditions and covenants of the new credit facilities may differ in important respects from those we describe below.

Hologic Loan Parties. The commitment letter contemplates that Hologic will be the borrower under the new facilities and that all obligations under the facilities will be guaranteed by all domestic subsidiaries of Hologic, including Cytyc and its subsidiaries, provided that neither immaterial subsidiaries of Hologic nor any subsidiary of Hologic that is a Massachusetts securities corporation will be a guarantor. Hologic and the subsidiary guarantors under the new facilities are referred to as the Hologic loan parties.

Credit Facilities. It is contemplated that Hologic will obtain up to $2.55 billion principal amount of credit facilities on the closing date of the merger. The credit facilities to be obtained on the merger closing date will consist of:

| • |  | a senior secured tranche B term loan facility, known as the term loan B facility, in a total principal amount of up to $1.35 billion;

| • |  | a senior secured capital markets term loan, known as the term loan X facility, in a total principal amount of up to $1.0 billion; and

| • |  | a revolving credit facility in a total available principal amount of up to $200 million, provided that no more than $100 million of this facility may be drawn on the merger closing date.

The commitment letter contemplates that Hologic may elect, after the closing date and subject in certain circumstances to pro forma compliance by the Hologic loan parties with a specified ratio of total debt to adjusted consolidated EBITDA and other conditions, to increase, under terms and conditions to be determined, the total principal amount of borrowings available under the credit facilities by up to $1.0 billion, subject to reduction for up to $500 million of prepayment of the term loan X facility. EBITDA means earnings before interest, taxes, depreciation and amortization.

Security. The commitment letter contemplates that the obligations of the Hologic loan parties under the credit facilities will be secured by first-priority liens on, and first-priority security interests in, substantially all of their assets and a first priority security interest in 100% of the capital stock of each guarantor, 65% of the capital stock of each of the first-tier foreign subsidiaries of Hologic (other than immaterial foreign subsidiaries) and all intercompany debt.

Maturity and Principal Payments. The commitment letter contemplates that the final maturity dates for the credit facilities will be as follows:

| • |  | for the term loan B facility, 5.5 years after the merger closing date;

| • |  | for the term loan X facility, 18 months after the merger closing date; and

| • |  | for the revolving loan facility, 5 years after the merger closing date.

The commitment letter contemplates that Hologic will be required to make scheduled principal payments under the term facility, in equal quarterly installments of 0.25% of the total principal amount of the term loan B facility as of the merger closing date during the first 21 quarters after the merger closing date with the remaining

59

##### Table of Contents

balance due at the maturity of the term loan B facility. The revolving credit facility and the term loan X facility are contemplated to become due at maturity. The commitment letter contemplates that no amortizations will be required under the revolving facility or the capital markets facility.

The commitment letter contemplates that Hologic will be required to make principal repayments first, pro rata to the term loan B facility and term loan X facility and second to the revolving credit facility from specified excess cash flows from operations and from the net proceeds of specified types of asset sales, debt issuances, insurance recoveries and equity offerings.

The commitment letter contemplates that Hologic may voluntarily prepay any of the credit facilities without premium or penalty (other than applicable breakage costs related to interest on Eurodollar loans).

Interest Payments; Revolver Commitment Fee. The commitment letter contemplates that borrowings outstanding under the facilities will bear interest, at Hologic’s option, at an annual rate equal to either:

| • |  | a specified “base rate” plus a margin based on corporate family-corporate credit ratings; or

| • |  | a specified Eurodollar rate plus a margin based on corporate family-corporate credit rating.

The margin applicable to loans under the revolving credit facility is subject to specified reductions based on certain reductions in a specified leverage ratio to be negotiated.

The commitment letter contemplates that borrowings outstanding under the new credit facilities with reference to a base rate generally will be payable by Hologic on a quarterly basis. For credit facilities bearing interest with reference to Eurodollar rates, interest shall be payable on the last day of selected interest periods (which shall be one, two, three and six months) unless the interest period exceeds three months, in which case, interest will be due at the end of every three months.

The commitment letter contemplates that Hologic will pay a quarterly commitment fee, at an annual rate of 0.50%, on the undrawn commitments available under the revolving credit facility, subject to reduction based on a leverage ratio to be negotiated.

Covenants. The commitment letter contemplates that the new credit facilities will contain affirmative and negative covenants customarily applicable to senior secured credit facilities, including covenants restricting the ability of the Hologic loan parties, subject to negotiated exceptions, to:

| • |  | incur additional indebtedness and additional liens on their assets;

| • |  | engage in mergers or acquisitions or dispose of assets;

| • |  | enter into sale-leaseback transactions;

| • |  | pay dividends or make other distributions;

| • |  | voluntarily prepay other indebtedness;

| • |  | enter into transactions with affiliated persons;

| • |  | make investments; and

| • |  | change the nature of their businesses.

The commitment letter contemplates that, under the revolving credit facility, the Hologic loan parties will be required to maintain a maximum leverage ratio.

Other Provisions. The commitment letter contemplates that the definitive loan documents will contain customary representations and warranties by the Hologic loan parties, as well as customary events of default,

60

##### Table of Contents

including an event of default upon a change of control of Hologic. Hologic expects that an event of default will occur under the new credit facilities if it or, in some circumstances, another Hologic loan party fails to make any payment when due, fails to comply with affirmative or negative covenants, makes a misrepresentation, defaults on other specified indebtedness, fails to discharge specified judgments, becomes subject to specified claims under ERISA, or becomes subject to specified events of bankruptcy. If an event of default occurs and is not cured within any applicable grace period or is not waived, the lenders would have the right to accelerate repayment of the indebtedness under the credit facilities to the extent provided in the credit documents and applicable law. If its indebtedness were accelerated, Hologic may not have sufficient funds to pay such indebtedness. In such event, Hologic’s lenders would be entitled to enforce their security interests in the collateral securing the indebtedness, which will include substantially all of the assets of Hologic and its subsidiaries.

Anticipated Post-merger Refinancing. As soon as practicable after the effective time of the merger, Hologic intends to cause the combined company to seek to refinance a substantial portion of the debt incurred under the proposed new credit facilities with convertible debt or other equity or equity-linked financing, with reduced interest rates, extended maturity and limited or no restrictive or other financial covenants.

Opinions of Financial Advisors to the Hologic Board of Directors

Hologic retained Goldman Sachs and Jefferies as financial advisors to the Hologic board of directors in connection with the merger.

On May 19, 2007, at a meeting of the Hologic board of directors held to evaluate the proposed merger, each of Goldman Sachs and Jefferies delivered to the Hologic board of directors separate oral opinions, which opinions were confirmed by delivery of separate written opinions dated May 20, 2007, to the effect that, as of that date and based on and subject to the assumptions, procedures, factors, limitations and qualifications set forth in each such opinion, the merger consideration to be paid for each outstanding share of Cytyc common stock, taken in the aggregate, to be paid pursuant to the merger agreement, was fair, from a financial point of view, to Hologic.

Goldman Sachs’ and Jefferies’ opinions dated May 20, 2007, the full texts of which describe the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Goldman Sachs and Jefferies, are attached hereto as Annex C and Annex D, respectively, and are incorporated into this joint proxy statement/prospectus by reference. Goldman Sachs’ and Jefferies’ opinions were directed only to the fairness to Hologic, from a financial point of view, of the merger consideration provided for in the merger and do not address any other aspect of the merger. The opinions do not address the relative merits of the merger as compared to other business strategies or transactions that might be available with respect to Hologic or Hologic’s underlying business decision to effect the merger. The opinions do not constitute a recommendation as to how any holder of Hologic common stock or Cytyc common stock should vote at any stockholders’ meeting to be held in connection with, or take any action with respect to, the merger. Holders of Hologic common stock are encouraged to read the opinions carefully in their entirety. The summaries of Goldman Sachs’ and Jefferies’ opinions described below are qualified in their entirety by reference to the full texts of the opinions.

Opinion of Goldman Sachs. At the special meeting of the Hologic board of directors on May 19, 2007, Goldman Sachs rendered its oral opinion, subsequently confirmed in writing, to the Hologic board of directors that, as of that date and based upon and subject to the assumptions, procedures, factors, limitations and qualifications set forth in such opinion, the merger consideration to be paid for each outstanding share of Cytyc common stock, taken in the aggregate, to be paid pursuant to the merger agreement, was fair, from a financial point of view, to Hologic.

##### Table of Contents

review undertaken in connection with its opinion, is attached as Annex C to this joint proxy statement/ prospectus and is incorporated herein by reference. Hologic stockholders should read the opinion in its entirety. Goldman Sachs provided its opinion for the information and assistance of the Hologic board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Hologic common stock or Cytyc common stock should vote at any stockholders’ meeting to be held in connection with, or take any action with respect to, the merger.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs has reviewed, among other things:

| • |  | the merger agreement;

| • |  | annual reports to stockholders and annual reports on Form 10-K of Hologic and Cytyc for the five fiscal years ended on the Saturday closest to September 30, 2006 for Hologic, and December 31, 2006 for Cytyc;

| • |  | certain interim reports to stockholders and quarterly reports on Form 10-Q of Hologic and Cytyc;

| • |  | certain other communications from Hologic and Cytyc to their respective stockholders;

| • |  | certain internal financial analyses and forecasts for Cytyc prepared by its management, as reviewed by the management of Hologic, and certain internal financial analyses and forecasts for Hologic prepared by its management and certain internal pro forma analyses and forecasts of Hologic and Cytyc prepared by the management of Hologic; and

| • |  | certain cost savings and operating synergies projected by the respective managements of Hologic and Cytyc to result from the transaction.

Goldman Sachs also held discussions with members of the senior management of Hologic and Cytyc regarding their assessment of the strategic rationale for, and the potential benefits of, the transaction and the past and current business operations, financial condition, and future prospects of Hologic and Cytyc. In addition, Goldman Sachs reviewed the reported price and trading activity for the shares of Hologic common stock and the shares of Cytyc common stock, compared certain financial and stock market information for Hologic and Cytyc with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the medical device and diagnostics industry specifically and in other industries generally, and performed such other studies and analyses, and considered such other factors, as it considered appropriate.

Goldman Sachs has relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of the opinion described above. Goldman Sachs assumed, with the consent of the Hologic board of directors, that the financial forecasts and the cost savings and operating synergies projected by Hologic and Cytyc, were reasonably prepared on a basis reflecting the then best currently available estimates and judgments of the management of Hologic and Cytyc. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of Hologic or Cytyc or any of their respective subsidiaries and no such evaluation or appraisal was furnished to Goldman Sachs.

Goldman Sachs’ opinion did not address the underlying business decision of Hologic to engage in the merger, nor did Goldman Sachs express any opinion as to the prices at which shares of Hologic common stock or Cytyc common stock will trade at any time. Goldman Sachs also assumed that all governmental, regulatory or other consents and approvals necessary for completion of the transaction will be obtained without any adverse effect on Hologic or Cytyc or on the expected benefits of the transaction in any way meaningful to its analysis. Goldman Sachs’ opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Goldman Sachs as of, the date therein.

Cytyc Implied Financial Analysis

Transaction Overview and Valuation Statistics. Goldman Sachs reviewed with the Hologic board of directors the basic structure of the transaction as described to Goldman Sachs by Hologic management, including the following:

| • |  | consideration of $16.50 and 0.52 shares of Hologic common stock for each share of Cytyc common stock;

| • |  | the implied offer price of $46.46 per share (based on the May 18, 2007 closing price of Hologic’s common stock of $57.61); and

| • |  | pro forma ownership, based on 132.4 million diluted shares of Cytyc common stock outstanding, by current Hologic stockholders of approximately 45% of the combined company.

Goldman Sachs calculated for the Hologic board of directors various multiples and premiums resulting from the merger, based on information provided by Hologic management and Cytyc management (as used herein, reference to information provided by Cytyc management refers to such information as reviewed and adjusted by Hologic management). The following table presents the results of Goldman Sachs’ calculations:

|  | Implied Transaction Multiples Without Synergies |  | Implied Transaction Multiples With Synergies (1)
FY 2008E EBITDA |  | 16.3x |  | 15.2x
FY 2009E EBITDA |  | 13.3x |  | 12.5x
FY 2008E Cash Net Income |  | 28.6x |  | 26.6x
FY 2009E Cash Net Income |  | 22.8x |  | 21.3x
FY 2008E GAAP Net Income |  | 30.9x |  | 28.5x
FY 2009E GAAP Net Income |  | 24.5x |  | 22.8x

(1) | Potential cost synergies of $25 million to $30 million within two years, based on Hologic and Cytyc management preliminary projections.

Comparable Trading Multiple Analysis. Goldman Sachs reviewed and compared certain financial information of Cytyc to corresponding financial information, ratios and public market multiples for these publicly traded companies in the medical device and specialized diagnostics industry:

| • |  | Ventana Medical Systems, Inc.;

| • |  | Hologic;

##### Table of Contents

| • |  | Digene Corp.;

| • |  | Immucor, Inc.;

| • |  | Gen-Probe Inc.; and

| • |  | American Medical Systems Holdings, Inc.

Although none of the selected companies is directly comparable to Cytyc, the companies included were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to certain operations of Cytyc.

Goldman Sachs calculated and compared various financial multiples and ratios for the selected companies and for Cytyc, based on financial data as of May 18, 2007, estimates for the selected companies from Institutional Brokerage Estimate System (IBES), and Cytyc management’s projections of Cytyc as adjusted to Hologic’s September fiscal year end. With respect to the selected companies and Cytyc, Goldman Sachs calculated enterprise value, which is the market value of common equity plus the estimated market value of debt less cash, as a multiple of 2007E and 2008E earnings before interest, taxes and depreciation and amortization (EBITDA). Goldman Sachs also calculated, based on fiscal year end Cytyc management projections adjusted to Hologic September fiscal year end, the implied transaction value multiples for 2007E and 2008E EBITDA (with and without synergies projected by Cytyc’s and Hologic’s respective managements ). Goldman Sachs compared the multiples of the selected companies to the implied transaction multiples. The result of this analysis is summarized as follows:

|  |  |  | Implied Transaction Value Multiples
Enterprise value as a multiple of: |  | Selected Companies Range |  | Without Synergies |  | With Synergies
2007E EBITDA |  | 14.8x –28.9x |  | 21.0x |  | 20.3x
2008E EBITDA |  | 11.7x –19.0x |  | 16.3x |  | 15.2x

With respect to the selected companies, Goldman Sachs also calculated the ratio of market price to earnings (P/E ratio) for 2007E and 2008E earnings (based on generally accepted accounting principles (GAAP) net income). Goldman Sachs compared the P/E ratios of the selected companies to the implied transaction value P/E ratios. With respect to Cytyc, Goldman Sachs calculated the implied transaction value P/E ratios for 2007E and 2008E earnings for:

| • |  | projected GAAP net income;

| • |  | cash net income without synergies; and

| • |  | cash net income with synergies projected by Cytyc’s and Hologic’s respective managements.

Each of the implied transaction value P/E ratio calculations above was based on fiscal year end Cytyc management projections adjusted to Hologic’s September fiscal year end. The result of this analysis is summarized as follows:

|  |  |  | Implied Transaction Value P/E Ratios
P/E ratio |  | Selected Companies Range |  | GAAP Net Income |  | Cash Net Income Without Synergies |  | Cash Net Income With Synergies
2007E |  | 33.1x –39.2x |  | 40.9x |  | 37.3x |  | 35.9x
2008E |  | 19.2x –33.2x |  | 30.9x |  | 28.6x |  | 26.6x

Although none of the selected transactions or the companies party to the transactions is directly comparable to the merger or to Hologic or Cytyc, the above transactions were chosen because they involve transactions that, for purposes of analysis, may be considered similar to the merger and/or involve publicly traded companies with operations that, for purposes of analysis, may be considered similar to certain operations of Hologic and Cytyc.

For each of the selected transactions, Goldman Sachs calculated and, to the extent information was publicly available, compared enterprise value as a multiple of each of sales, EBITDA and earnings before interest and taxes (EBIT), in each case, on a GAAP net income basis and for the latest twelve months, or LTM, prior to the date that the merger was announced, and compared such multiples to the implied Cytyc transaction value multiples. The following tables present the results of this analysis:

|  | Implied Transaction Value as Multiple of LTM |
Selected Transactions |  | Sales |  |  | EBITDA |  |  | EBIT |
High |  | 8.8 | x |  | 42.5 | x |  | 60.4 | x
Mean |  | 4.8 | x |  | 20.6 | x |  | 29.6 | x
Median |  | 4.5 | x |  | 18.4 | x |  | 27.5 | x

Goldman Sachs also calculated the premiums paid based on the closing stock price of the target one day prior to the announcement of each transaction, and premium paid based on the closing stock price of the target one month prior to the announcement of each transaction or the undisturbed stock price in contested situations, and compared such premiums to the premium derived from the implied Cytyc transaction value multiples. The following tables present the results of this analysis:

Selected Transactions |  | Premium one day prior |  |  | Premium one month prior |
High |  | 117.4 | % |  | 163.2 | %

Cytyc Discounted Cash Flow Analysis. Goldman Sachs performed a discounted cash flow analysis on Cytyc using the financial forecasts provided by Cytyc management. Goldman Sachs calculated implied net present values of projected free cash flows for Cytyc, as provided by Cytyc management, for the years 2007 through 2011 using discount rates ranging from 8.0% to 10.0% and using terminal values in the year 2011 based on forward after tax earnings before interest, taxes and amortization (EBITA) multiples ranging from 18.0x to 22.0x. These analyses indicated implied Cytyc equity value per share from $50.38 to $63.25 per share. In addition, for the benefit of Hologic management and the Hologic board of directors, Goldman Sachs ran a downside sensitivity case analysis based on a 9.0% discount rate and a 20.0x forward after tax EBITA multiple with a range of decrease in Cytyc margin from 0.0% to 4.0% and a range of decrease in Cytyc revenue growth between 0.0% to 6.0%, which analysis indicated implied Cytyc equity value per share from $42.76 to $56.65 per share.

Comparative and Contribution Analysis

Comparative Discounted Cash Flow Analyses. Goldman Sachs performed a comparative discounted cash flow analysis on Hologic and the combined company using the financial forecasts provided by Hologic management, Cytyc management and, in the case of the combined company, the savings from synergies and benefits projected by Hologic and Cytyc management to be realized following the merger.

Goldman Sachs calculated implied net present values of projected free cash flows for Hologic on a standalone and pro forma basis based on forecasts provided by Hologic management and Cytyc management, for the years 2007 through 2011 using discount rates ranging from 9.0% to 11.0% and using terminal values in the year 2011 based on forward after tax EBITA multiples ranging from 18.0x to 22.0x. Hologic management provided two alternative forecasts, management’s base case and an upside sensitivity case (the primary difference of which is, for illustrative sensitivity purposes, increases in the compounded annual growth rates for revenue and improvements in the operating margins). Goldman Sachs calculated implied equity values per share without synergies for Hologic on a standalone and with and without synergies on a pro forma basis, based on Hologic management’s and Cytyc management’s preliminary estimates of synergies. The pro forma values exclude the impact of Hologic and Cytyc net operating losses, assume a mid-year convention and 37.0% tax rate, and are discounted to September 30, 2007. The pro forma discounted cash flow analysis assumes $2.186 billion of pro forma net debt based on total cash financing needs and cash balances as of September 30, 2007, and 125.8 million pro forma fully diluted shares (including Hologic shares to be issued in a small, pending private acquisition).

The analysis based on the forecasts resulted in implied standalone Hologic equity value per share ranges ranging from $45.68 to $68.62. With respect to the combined company, the analysis resulted in implied pro forma equity value per share ranges ranging from $54.73 to $78.68 with synergies and $52.38 to $75.76 without synergies.

Illustrative Contribution Analysis. Goldman Sachs analyzed and compared the relative contributions to be made by each of Hologic and Cytyc, based on the forecasts of EBITDA and cash net income for fiscal years 2008 through 2011 provided by Hologic management and Cytyc management, for both the management base case and the upside sensitivity case and with and without synergies provided by Hologic management and Cytyc management preliminary estimates.

For comparison to the approximately 45% ownership that will be retained by Hologic in the combined company, Goldman Sachs calculated the implied percentage of equity for both Hologic and Cytyc based on their relative contribution to EBITDA and Cash Net Income by using Hologic’s implied trading multiples for the alternative forecasts. Included in these analyses were potential cost synergies based on Hologic management’s and Cytyc management’s preliminary estimates. The following table presents the results of these analyses on a blended range basis:

|  | % Contribution FY 2008E – FY 2011E |  |  | Implied % of Equity Based on Hologic Current Trading Multiples Without Synergies FY 2008E – FY 2011E |  |  | Implied % of Equity Based on Hologic Current Trading Multiples With Synergies FY 2008E – FY 2011E |
|  | High |  |  | Low |  |  | High |  |  | Low |  |  | High |  |  | Low |
EBITDA |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Hologic |  | 36.9 | % |  | 27.1 | % |  | 53.6 | % |  | 35.5 | % |  | 50.7 | % |  | 34.2 | %
Cytyc |  | 72.9 | % |  | 63.1 | % |  | 64.5 | % |  | 46.4 | % |  | 65.8 | % |  | 49.3 | %
Cash Net Income |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Hologic |  | 45.0 | % |  | 30.0 | % |  | 58.9 | % |  | 34.8 | % |  | 55.1 | % |  | 33.5 | %
Cytyc |  | 70.0 | % |  | 55.0 | % |  | 65.2 | % |  | 41.1 | % |  | 66.5 | % |  | 44.9 | %

The above analysis assumes equivalent multiples are applied to both Hologic and Cytyc. Goldman Sachs derived the implied equity value of the pro forma company by adjusting Cytyc’s implied enterprise value for transaction debt of $2.286 billion and cash of $42 million. Each analyses also assumes that Hologic’s equity value was $3.283 billion as of May 18, 2007, that Hologic completes a small, pending private acquisition and assumes the pro forma capital structure as applied to Cytyc, which would result in an after tax pro forma interest expense deduction to Cytyc cash net income.

Pro Forma Analysis

Pro Forma Accretion/Dilution Analysis. Goldman Sachs compared, for each of the years 2008 and 2009, the forecast earnings per share, referred to as EPS, of Hologic, on a cash EPS and GAAP EPS standalone basis, in relation to the estimated GAAP EPS and the estimated cash EPS of the combined company, with and without synergies. In connection with the analysis, Goldman Sachs used EPS estimates under the forecast alternatives prepared by Hologic management and EPS estimates provided by Cytyc management. Goldman Sachs considered the potential cost synergies, based on Hologic management and Cytyc management preliminary estimates, and the 2008 figures included a $10 million management retention expense as provided by Hologic management. The analysis indicated that, while the transaction would be meaningfully dilutive on a GAAP basis, it would be accretive on a cash EPS basis taking into account synergies. In addition, such analysis was based on preliminary purchase accounting assumptions reviewed with Goldman Sachs by Hologic management.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after

67

##### Table of Contents

considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Hologic or the contemplated transaction.

Goldman Sachs prepared these analyses for purposes of Goldman Sachs providing its opinion to the Hologic board of directors that, as of May 20, 2007 and based upon and subject to the assumptions, procedures, factors, limitations and qualifications set forth in such opinion, the merger consideration to be paid for each outstanding share of Cytyc common stock, taken in the aggregate, pursuant to the merger agreement was fair, from a financial point of view, to Hologic. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Hologic, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

The merger consideration was determined through arm’s-length negotiations between Hologic and Cytyc and was approved by the Hologic board of directors. Goldman Sachs provided advice to Hologic during these negotiations. Goldman Sachs did not, however, recommend any specific amount of consideration to Hologic or its board of directors or that any specific merger consideration constituted the only appropriate consideration for the merger.

As described above, the opinion of Goldman Sachs to the Hologic board of directors was one of many factors taken into consideration by the Hologic board of directors in making its determination to approve the transaction. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex C.

Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Goldman Sachs has acted as financial advisor to Hologic in connection with, and has participated in certain of the negotiations leading to, the transaction contemplated by the merger agreement. In addition, Goldman Sachs has provided certain investment banking services to Hologic and Cytyc from time to time, for which Goldman Sachs has received, and may receive, compensation. Goldman Sachs also may provide investment banking services to Hologic in the future for which Goldman Sachs may receive compensation. In addition, Goldman Sachs expects that it and its affiliates will arrange and/or provide financing to Hologic specifically in connection with the transaction for additional compensation.

Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide such services to Hologic, Cytyc and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of Hologic and Cytyc for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

The Hologic board of directors selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the contemplated transaction. Pursuant to a letter agreement, dated May 8, 2007, Hologic engaged Goldman Sachs to act as its financial advisor in connection with the transaction. Pursuant to the terms of this letter agreement, Hologic has agreed to pay Goldman Sachs a transaction fee of $16 million upon completion of the merger. In

addition, Hologic has agreed to reimburse Goldman Sachs’ expenses incurred in connection with this engagement and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

Opinion of Jefferies. Jefferies was engaged to render an opinion to Hologic’s board of directors as to whether the merger consideration to be paid by Hologic pursuant to the merger agreement is fair, from a financial point of view, to Hologic. On May 19, 2007, Jefferies delivered to the Hologic board of directors its oral opinion, subsequently confirmed in writing, that, as of the date of its opinion, based upon and subject to the assumptions, limitations, qualifications and factors contained in its opinion, the merger consideration to be paid by Hologic pursuant to the merger agreement is fair, from a financial point of view, to Hologic.

The full text of the written opinion of Jefferies is attached to this joint proxy statement/prospectus as Annex D and incorporated into this joint proxy statement/prospectus by reference. We urge you to read that opinion carefully and in its entirety for the assumptions made, procedures followed, other matters considered and limits of the review undertaken in arriving at that opinion.

Jefferies’ opinion is for the use and benefit of the Hologic board of directors in its consideration of the merger, and Jefferies’ opinion does not address the relative merits of the transactions contemplated by the merger agreement as compared to any alternative transaction or opportunity that might be available to Hologic, nor does it address the underlying business decision by Hologic to engage in the merger or the terms of the merger agreement or the documents referred to therein. Jefferies’ opinion does not constitute a recommendation as to how any holder of shares of Hologic common stock should vote on the merger or any matter related thereto. In addition, Hologic did not ask Jefferies to address, and Jefferies’ opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Hologic. Jefferies expresses no opinion as to the price at which shares of Hologic common stock would trade at any time.

In arriving at its opinion, Jefferies, among other things:

| (i) | reviewed a draft dated May 19, 2007 of the merger agreement;

| (ii) | reviewed certain publicly available financial and other information about Hologic and Cytyc;

| (iii) | reviewed certain information furnished to Jefferies by Hologic’s management, including financial forecasts and analyses, relating to the business, operations and prospects of Hologic;

| (iv) | reviewed certain information furnished to Jefferies by Cytyc’s management and Hologic’s management, including financial forecasts and analyses, relating to the business, operations and prospects of Cytyc;

| (v) | held discussions with members of senior management of Hologic concerning the matters described in clauses (ii), (iii) and (iv) above;

| (vi) | held discussions with members of senior management of Cytyc concerning the matters described in clause (ii) and (iv) above;

| (vii) | reviewed certain publicly available information, including share trading price history and valuation multiples, of certain publicly traded companies that Jefferies deemed comparable to Cytyc;

| (viii) | compared the proposed financial terms of the merger with the financial terms of certain other transactions that Jefferies deemed relevant; and

| (ix) | conducted such other financial studies, analyses, and investigations as Jefferies deemed appropriate.

In Jefferies’ review and analysis and in rendering its opinion, Jefferies assumed and relied upon, but did not independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by Hologic or Cytyc or that was publicly available to Jefferies, or that was

69

##### Table of Contents

otherwise reviewed by Jefferies. In Jefferies’ review, Jefferies did not obtain any independent evaluation or appraisal of any of the assets or liabilities of, nor did Jefferies conduct a physical inspection of any of the properties or facilities of Hologic or Cytyc, nor was Jefferies furnished with any such evaluations or appraisals of such physical inspections, nor does Jefferies have any responsibility to obtain any such evaluations or appraisals.

With respect to the financial forecasts provided to and examined by Jefferies, Jefferies notes that projecting future results of Hologic and Cytyc is inherently subject to uncertainty. Hologic and Cytyc informed Jefferies, and Jefferies assumed, that such financial forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Hologic and Cytyc as to the future financial performance of Hologic and Cytyc, respectively. Jefferies expresses no opinion as to such financial forecasts or the assumptions on which they were made.

Jefferies made no independent investigation of any legal or accounting matters affecting Hologic or Cytyc, and assumed the correctness in all respects material to Hologic’s analysis of all legal and accounting advice given to Hologic and its board of directors, including, without limitation, advice as to the legal, accounting and tax consequences of the terms of, and transactions contemplated by, the merger agreement to Hologic and its stockholders. In addition, in preparing its opinion, Jefferies did not take into account any tax consequences of the transaction to Hologic. Jefferies assumed that the final form of the merger agreement would be substantially similar to the last draft reviewed by Jefferies. Jefferies also assumed that in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Hologic, Cytyc or the contemplated benefits of the merger.

Jefferies’ opinion was based on economic, monetary, regulatory, market and other conditions existing and that could be evaluated as of the date of its opinion. Jefferies has no obligation to advise any person of any change in any fact or matter affecting its opinion of which Jefferies may have become aware of or of which Jefferies could become aware after the date of its opinion.

The following is a brief summary of the analyses performed by Jefferies in connection with its opinion. This summary is not intended to be an exhaustive description of the analyses performed by Jefferies but includes all material factors considered by Jefferies in rendering its opinion. Jefferies drew no specific conclusions from any individual analysis, but subjectively factored its observations from all of these analyses into its qualitative assessment of the merger consideration. Each analysis performed by Jefferies is a common methodology utilized in determining valuations. Although other valuation techniques may exist, Jefferies believes that the analyses described below, when taken as a whole, provide the most appropriate analyses for Jefferies to arrive at its opinion.

Comparable Public Company Analysis

Jefferies utilized comparable public company analysis, which values a target company by reference to publicly-traded companies with similar products, similar operating and financial characteristics and similar markets. Jefferies reviewed and compared selected financial data for six publicly traded companies chosen by Jefferies that were deemed to be comparable to Cytyc based on similar market capitalizations; revenue growth rates; gross margins and EBITDA (earnings before interest, taxes, depreciation and amortization) margins; similar business models; and participation in similar, high-growth medical device markets. The comparable companies chosen by Jefferies included:

Digene Corporation |  | Meridian Bioscience, Inc.
Gen-Probe Incorporated |  | Quidel Corporation
Inverness Medical Innovations, Inc. |  | Ventana Medical Systems, Inc.

##### Table of Contents

For each of the comparable companies, Jefferies calculated the ratios of the company’s total enterprise value (“TEV”) as of May 18, 2007 to analyst estimates of that company’s 2007 EBITDA. TEV was calculated as market capitalization, plus total debt, less cash and cash equivalents. Jefferies also calculated price-to-earnings ratio for each comparable company by dividing each company’s respective closing stock price on May 18, 2007 by (i) consensus analyst estimates of that company’s 2007 and 2008 GAAP earnings per share (“EPS”), including the impact of stock option expenses, and (ii) analyst estimates of that company’s 2007 and 2008 cash EPS, including the impact of stock option expenses. Jefferies used information available in publicly available research reports for estimated EBITDA, estimated GAAP EPS and estimated cash EPS.

Jefferies next calculated the corresponding implied multiples for Cytyc in the merger on the same basis, but defining equity market capitalization (for purposes of calculating TEV) as the $46.46 proposed per share merger consideration multiplied by the sum of the number of diluted shares outstanding plus the additional shares that would be issued upon conversion of convertible notes. Such calculations consisted of the ratios of Cytyc’s TEV (based on the $46.46 proposed per share merger consideration) to Hologic management’s projections of Cytyc EBITDA for the current fiscal year ending December 31, 2007. In addition, Jefferies calculated price-to-earnings ratios based on the $46.46 proposed per share merger consideration to (i) Hologic management’s projections of Cytyc GAAP earnings per share and cash earnings per share for the current fiscal year ending December 31, 2007; and (ii) Hologic management’s projections of Cytyc GAAP earnings per share and cash earnings per share for the next full fiscal year ending December 31, 2008. Jefferies then compared such implied multiples for Cytyc in the merger to the multiples for the comparable companies.

The resulting multiples and implied multiples are set forth in the table below:

Comparable Companies |  | High Comparable Multiple |  | Low Comparable Multiple |  | Mean Comparable Multiple |  | Median Comparable Multiple |  | Implied Multiple Cytyc at $46.46
1) Multiple of TEV/2007E EBITDA |  | 29.6x |  | 12.3x |  | 18.4x |  | 18.2x |  | 19.0x
2) Multiple of Price/2007E GAAP Earnings |  | 49.7x |  | 23.0x |  | 36.2x |  | 36.8x |  | 33.7x
3) Multiple of Price/2007E Cash Earnings |  | 38.0x |  | 22.1x |  | 32.0x |  | 34.5x |  | 31.3x
4) Multiple of Price/2008E GAAP Earnings |  | 34.3x |  | 18.6x |  | 26.0x |  | 27.9x |  | 26.1x
5) Multiple of Price/2008E Cash Earnings |  | 33.4x |  | 16.0x |  | 24.7x |  | 27.7x |  | 24.2x

No company utilized in the comparable public company analysis is identical to Cytyc. Jefferies made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions, and other matters, many of which are beyond the control of Cytyc. Mathematical analysis of comparable public companies (such as determining means and medians) in isolation from other analyses is not an effective method of evaluating transactions.

Comparable Transaction Analysis

Jefferies utilized comparable transaction analysis, a method of valuing a business relative to recent merger and acquisition transactions involving similar businesses. Jefferies analyzed eleven previous outright acquisitions of small- and mid-cap public target companies and emerging growth private target companies with one or more of the following characteristics: market leader in high-growth niches of medical technology; focus on diagnostics and women’s health; and strong strategic fit with the acquirer based on similar physician call point/complementary products. The comparable transactions chosen by Jefferies included:

For each of these transactions, Jefferies initially calculated the ratios of the TEV of the transaction (based on the acquisition price) to the target company’s EBITDA for the latest twelve month period (“LTM”) ended on the last day of the period covered by the target company’s Form 10-K or Form 10-Q, as applicable, last filed prior to the announcement of the relevant transaction. In calculating such ratios, Jefferies calculated TEV of the transaction as the market value of the relevant target company’s equity securities plus its indebtedness and minority interests less its cash and cash equivalents.

Jefferies also calculated the ratios of the total equity value in each comparable transaction to (i) estimates of GAAP earnings and cash earnings for the target company’s then current fiscal year and (ii) the target company’s next full fiscal year. The estimates used by Jefferies for each target company’s forward earnings were available in publicly available research reports.

Jefferies next calculated corresponding implied multiples for Cytyc in the Merger. Such calculations consisted of the ratio of Cytyc’s TEV (based on the $46.46 proposed per share merger consideration) to Cytyc’s EBITDA from March 31, 2006 to March 31, 2007. In addition, Jefferies calculated price-to-earnings ratios based on the $46.46 proposed per share merger consideration to (i) Hologic management’s projections of Cytyc GAAP earnings and cash earnings for the current fiscal year ending December 31, 2007; and (ii) Hologic management’s projections of Cytyc GAAP earnings and cash earnings for the next full fiscal year ending December 31, 2008. Jefferies then compared such implied multiples for Cytyc in the merger to the multiples for the precedent transactions.

The following table sets forth Jefferies’ analysis:

Comparable Transactions |  | High Comparable Multiple |  | Low Comparable Multiple |  | Mean Comparable Multiple |  | Median Comparable Multiple |  | Implied Multiple Cytyc at $46.46
Multiple of TEV /LTM EBITDA |  | 29.4x |  | 10.8x |  | 22.5x |  | 24.6x |  | 24.5x

The transactions utilized in the comparable transaction analysis are not identical to the merger. In evaluating the transactions, Jefferies made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of either Hologic or Cytyc. Mathematical analysis of comparable transaction data in isolation from other analyses is not an effective method of evaluating transactions.

Discounted Cash Flow Analysis

Jefferies utilized discounted cash flow analysis, which values a company as the sum of its unlevered (before financing costs) free cash flows over a forecast period and the company’s terminal or residual value at the end of the forecast period. Jefferies examined the value of Cytyc based on projected free cash flow estimates, which were generated utilizing financial projections from June 30, 2007 through September 30, 2012 that were provided by Cytyc management and revised by Hologic management. A range of terminal values at September 30, 2011 was determined based on free cash flow in 2012 and applying perpetual growth rates from 5.0% to 6.0%, and discount rates of 11.5% to 12.5%. Jefferies selected its range of perpetual growth rates (5.0% - 6.0%) based on an average of growth rates over the long-term, which Jefferies deemed appropriate in light of projected above average growth in the near- and medium-term and an eventual maturing of the growth of free cash flows over the long-term.

Jefferies selected discount rates of 11.5% - 12.5% based on the Capital Asset Pricing Model, using a target capital structure for Cytyc. Based on the selected range of perpetual growth rates (5.0% - 6.0%) and discount rates (11.5% - 12.5%), Jefferies calculated implied Cytyc equity values per share ranging from $42.39 to $56.96 per share.

While discounted cash flow analysis is a widely accepted and practiced valuation methodology, it relies on a number of assumptions, including growth rates and discount rates. The valuation derived from the discounted cash flow analysis is not necessarily indicative of Cytyc’s present or future value or results. Discounted cash flow analysis in isolation from other analyses is not an effective method of evaluating transactions.

Premiums Paid Analysis

Jefferies utilized premiums paid analysis, a method of valuing a target business by analyzing the premiums paid in selected merger and acquisition transactions. Using publicly available information, Jefferies conducted premiums paid analysis of 24 change of control transactions involving target companies in the medical device industry announced since January 13, 2004.

73

##### Table of Contents

For each of the target companies involved in the 24 transactions, Jefferies examined the closing stock price one day prior to announcement of the relevant transaction in order to calculate the mean, median, minimum and maximum premiums paid by the acquirer over the target company’s closing stock price at those points in time. Jefferies then compared those premiums to the premium implied by the $46.46 proposed merger consideration over Cytyc’s undisturbed stock price of $35.05 on May 18, 2007, the date one trading day prior to the announcement of the merger. A summary of the one day premiums observed in this premiums paid analysis is set forth in the table below:

Premiums Paid |  | 1-Day |
Mean |  | 33.0 | %
Median |  | 25.3 | %
Maximum |  | 120.8 | %
Minimum |  | 5.1 | %
Proposed Merger Consideration (Cytyc) |  | 32.6 | %

Conclusion

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Jefferies considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Furthermore, Jefferies believes that selecting any portion of its analysis, without considering all analyses, would create an incomplete view of the process underlying its opinion.

In performing its analyses, Jefferies made numerous assumptions with respect to industry performance, and general business and economic conditions and other matters, many of which are beyond the control of Hologic and Cytyc. The analyses performed by Jefferies are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by such analyses. Jefferies did not recommend any specific consideration to the Hologic board of directors or that any specific consideration constituted the only appropriate consideration with respect to the merger agreement and the transactions contemplated thereby, including the merger.

Miscellaneous

Pursuant to an engagement letter dated May 15, 2007, the Hologic board of directors agreed to cause Hologic to pay Jefferies a fee in connection with rendering its opinion to the Hologic board of directors that is customary for transactions similar to the merger, and such fee was paid upon delivery of Jefferies’ opinion. The Hologic board of directors also agreed to cause Hologic to reimburse Jefferies for its expenses incurred in connection with rendering its opinion to the Hologic board of directors and to indemnify Jefferies against liabilities arising out of or in connection with the services rendered by Jefferies in connection to its engagement by the Hologic board of directors.

Jefferies maintains a market in Hologic securities and, in the ordinary course of business, Jefferies and its affiliates may trade or hold such securities for their own account and the accounts of their customers and, accordingly, may at any time hold long or short positions in those securities. Jefferies may seek to, in the future, provide financial advisory and financing services to Hologic or entities that are affiliated with Hologic, for which Jefferies would expect to receive compensation.

Interests of Hologic Executive Officers and Directors in the Merger

In considering the recommendation of the Hologic board of directors with respect to the merger, Hologic stockholders should be aware that certain executive officers of Hologic and members of the Hologic board of directors may have interests in the transactions contemplated by the merger agreement that are different than, or

##### Table of Contents

in addition to, the interests of the Hologic stockholders generally. The Hologic board of directors was aware of these interests and considered them, among other matters, in approving the merger and making its recommendation. These interests are summarized below.

Payments and Consideration to Executive Officers and Directors in Connection with the Merger.

Change of Control Agreements; Waivers. Each of Mr. John W. Cumming, Hologic’s current chairman and chief executive officer, Mr. Glenn P. Muir, Hologic’s current chief financial officer, Mr. Robert A. Cascella, Hologic’s current president and chief operating officer, and Dr. Jay A. Stein, Hologic’s current chairman emeritus and chief technical officer, have change of control agreements with Hologic, which provide that such officers are entitled to receive certain payments and benefits in connection with a change of control of Hologic. In addition, certain stock options and restricted stock unit award agreements for each of these officers provide that the officer’s unvested options and restricted stock units accelerate upon a change of control, except for restricted stock unit awards granted as a part of such officer’s existing retention and severance agreements.

In connection with entering into the merger agreement, each of Messrs. Cumming, Muir and Cascella agreed to waive, solely with respect to the change of control resulting from the merger, the change of control payment and special bonus they would have been entitled to receive under their respective change of control agreements and any accelerated vesting of the stock options and restricted stock units that were entitled to fully vest in connection with the merger. Each officer’s waiver provides that if such officer is terminated by Hologic other than for cause or if the officer resigns for good reason before the second anniversary of the merger then the waiver is rescinded. In connection with any rescission of the waiver, a change of control is deemed to have occurred at the effective time of the merger and the officer is entitled to receive all payments and benefits under his change of control agreement and all unvested options and restricted stock units that absent such waiver would have vested at the effective time of the merger shall become vested. These waivers do not apply to any change of control that may occur with respect to Hologic other than the merger. The following table sets forth the payments and other benefits that each of Messrs. Cumming, Muir and Cascella have conditionally waived under their respective change of control agreements that would become payable if their employment were terminated within two years of the effective date of the merger under the circumstances described above.

##### Table of Contents

(3) | All unvested stock options and restricted stock units, other than those restricted stock units issued in connection with the officer’s retention and severance agreement, would vest in connection with a change of control. More detail relating to the number and exercise price of such stock options is as follows (assuming the merger has a closing date of September 1, 2007):

| • |  | John W. Cumming: 60,000 options with an exercise price of $7.125 per share.

| • |  | Robert A. Cascella: 12,500 options with an exercise price of $6.80 per share; and 35,000 options with an exercise price of $7.125 per share.

| • |  | Glenn P. Muir: 35,000 options with an exercise price of $7.125 per share.

(4) | For purposes of the table set forth above, values are calculated (i) with respect to restricted stock units, by assuming that Hologic’s common stock price at the effective time of the merger is $55.00 per share and (ii) with respect to stock options, by subtracting the exercise price of the applicable stock option from the assumed $55.00 per share stock price of Hologic’s common stock at the effective time of the merger.

(5) | Amounts do not reflect any additional amounts paid to the executive which are necessary to pay any excise tax imposed upon the executive’s change of control payments and benefits pursuant to Section 4999 of the Code.

Under the terms of Dr. Stein’s change of control agreement he is entitled to a change of control payment in the amount of $1,800,000, which is equal to his base salary plus his highest annual bonus (as defined in his change of control agreement), multiplied by three. As a result of the merger, Dr. Stein will also be immediately vested in outstanding, unvested stock options to purchase 10,000 shares of Hologic common stock (having a value of $478,750, calculated by subtracting the exercise price of the stock options from an assumed $55.00 per share stock price of Hologic’s common stock price at the effective time of the merger) and 2,070 restricted stock units representing shares of Hologic common stock (having a value of $113,850, calculated by assuming that Hologic’s common stock price at the effective time of the merger is $55.00 per share). In addition, on the one year anniversary of the merger, Dr. Stein is entitled to receive a special bonus if he remains employed by Hologic. The special one time bonus is $600,000, which is equal to his then base salary plus his highest annual bonus. If Dr. Stein is terminated without cause or resigns for good reason prior to the one year anniversary of the merger, then Hologic is obligated to pay him the special bonus within thirty days of the termination date. Hologic is also obligated to gross up the amount paid Dr. Stein for excise taxes, if any, arising under Section 280G of the Code.

Non-Continuing Directors of Hologic. The compensation committee of the board of directors of Hologic approved certain benefits to be received at the effective time of the merger by those current independent directors of Hologic who will not continue as directors of Hologic following the merger. As of the date of this joint proxy statement/prospectus, the current independent directors of Hologic who will continue to serve as directors of Hologic following the merger have not been determined. Accordingly, the information provided below has been provided for each of the current independent directors of Hologic.

##### Table of Contents

| • |  | Stock Options Held by Non-Continuing Hologic Directors. Stock options to purchase shares of Hologic’s common stock held by independent directors who will not continue as directors of Hologic following the merger will vest and become fully exercisable upon the effective time of the merger and will remain exercisable until December 2009. The table below sets forth the name of each current Hologic director and the number of options that would vest assuming that individual did not continue as a director of Hologic after the merger:

Name |  | Number of Shares Underlying Stock Options that will Vest in connection with the Merger (1)
Laurie Fajardo(1) |  | 48,000
Irwin Jacobs(2) |  | 12,000
David LaVance, Jr.(3) |  | 12,000
Arthur Lerner(4) |  | 42,000
Nancy Leaming(5) |  | 22,000
Lawrence M. Levy(6) |  | 38,000

(2) | Consists of options to purchase 4,000 shares with an exercise price of $37.92; and options to purchase 8,000 shares with an exercise price of $47.28.

(3) | Consists of options to purchase 4,000 shares with an exercise price of $37.92; and options to purchase 8,000 shares with an exercise price of $47.28.

(4) | Consists of options to purchase 30,000 shares with an exercise price of $18.475; options to purchase 4,000 shares with an exercise price of $37.92; and options to purchase 8,000 shares with an exercise price of $47.28.

(5) | Consists of options to purchase 10,000 shares with an exercise price of $6.80; options to purchase 4,000 shares with an exercise price of $37.92; and options to purchase 8,000 shares with an exercise price of $47.28.

(6) | Consists of options to purchase 30,000 shares with an exercise price of $37.92; and options to purchase 8,000 shares with an exercise price of $47.28.

| • |  | Director Fees for Non-Continuing Directors. The compensation committee of the board of directors of Hologic also determined to accelerate the annual fees that otherwise would have been payable through March 2008 to those independent directors of Hologic who will not continue as directors after the merger. Accordingly, upon the effective time of the merger, each independent director of Hologic who will not continue as a director of Hologic following the merger will be entitled to receive the full amount of any unpaid annual fees payable through March 2008 to Hologic’s directors. The total amount of the annual fee payable to a director is $60,000 plus $7,500 for each chair of Hologic’s compensation, audit and corporate development committees. Assuming an effective time of the merger on September 1, 2007, the unpaid amounts that will be paid to each independent director of Hologic assuming such director does not continue as a director of Hologic following the merger is as follows: Ms. Fajardo: $30,000; Mr. Jacobs: $30,000; LaVance: $33,750; Dr. Lerner: $30,000; Ms. Leaming: $33,750; and Mr. Levy: $33,750.

Continuing Hologic Directors. As described under “Amendment to Hologic’s Second Amended and Restated 1999 Equity Incentive Plan,” each continuing Cytyc director that becomes an independent director of Hologic at the effective time of the merger will receive an automatic grant of options to purchase 50,000 shares of Hologic common stock pursuant to the terms of Hologic’s Second Amended and Restated 1999 Equity Incentive Plan. In

77

##### Table of Contents

connection with entering into the merger agreement, the parties agreed to treat all independent directors who will serve as directors of Hologic on the effective time of the merger similarly. Accordingly, subject to discretion and approval of the compensation committee of the board of directors of Hologic, it is expected that each continuing Hologic director who is an independent director will be granted options to purchase 50,000 shares of common stock of Hologic under Hologic’s Second Amended and Restated 1999 Equity Incentive Plan at the effective time of the merger.

The options to purchase 50,000 shares of Hologic common stock to be granted to all independent directors of Hologic at the effective time of the merger will become exercisable in 20% installments beginning on January 1 of the first year after the grant date, and on January 1 of each year thereafter, until such options are fully exercisable on January 1 of the fifth year following the grant. If the continuing Hologic directors receive their discretionary grant of options to purchase 50,000 shares of Hologic common stock, they have agreed to forego their automatic grant of options to purchase 8,000 shares of Hologic common stock that they would have otherwise received on January 1, 2008 pursuant to the terms of Hologic’s Second Amended and Restated 1999 Equity Incentive Plan. The continuing Cytyc directors are not eligible for the automatic grant of options to purchase 8,000 shares under Hologic’s Second Amended and Restated 1999 Equity Incentive Plan because such persons would not have been serving as a Hologic director for a period of six months before January 1, 2008.

Retention and Severance Agreements. In connection with Mr. Cascella’s waiver described above, Hologic and Mr. Cascella also agreed to the principal terms of a three year retention agreement, which will become effective upon and is subject to the completion of the merger. Mr. Cascella’s existing retention and severance agreement entered into in May 2006, will also remain in effect following the merger. Under the terms of the new retention agreement, Mr. Cascella will be entitled to a retention bonus in the amount equal to approximately $2,000,000 payable 50% in cash and 50% in restricted stock units if he remains employed by Hologic for three years following the effective time of the merger. The payment will be accelerated if Hologic terminates Mr. Cascella without cause or if Mr. Cascella resigns for good reason prior to such date. Termination for cause requires that 75% of Hologic’s independent directors determine that cause exists.

Other than as described above, no other employment arrangements with any Hologic executive officer were amended in connection with the merger agreement.

Board and Committee Composition of the Combined Company. Certain members of the Hologic board of directors will continue as directors of the combined company. As of the effective time of the merger, the board of directors of Hologic will consist of eleven directors, six of whom will be designated by Hologic and five of whom will be designated by Cytyc. Four of the six persons designated by Hologic will be “independent” directors, as defined under applicable Nasdaq listing standards, and the remaining two persons will be John W. Cumming, current chairman and chief executive officer of Hologic, and Glenn P. Muir, current chief financial officer of Hologic.

Hologic’s audit, nominating and corporate governance and corporate development committees following the merger will each consist of an odd number of directors, consisting of one more continuing Hologic director than continuing Cytyc directors. The chairman of each of these committees will be a continuing Hologic director. The compensation committee of Hologic following the merger will consist of an even number of directors, consisting of an equal number of continuing Cytyc directors and continuing Hologic directors. The chairman of the compensation committee will be a continuing Cytyc director. See “—Board of Directors and Management of Hologic Following the Merger; Headquarters” beginning on page 104.

Indemnification of Officers and Directors. In connection with entering into the merger agreement, Hologic’s board of directors approved an amendment to the indemnification provisions contained in Hologic bylaws. Such amendment will become effective only upon the effective time of the merger. The amended Hologic bylaws provide that Hologic will indemnify any person who was or is or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative,

78

##### Table of Contents

by reason of the fact that he is or was a director or officer of Hologic or, while a director or officer of Hologic, is or was serving at the request of Hologic as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, where the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such person in connection with such proceeding. The amended bylaws also provide that Hologic will indemnify any person seeking indemnification in connection with a proceeding brought by that person only if the proceeding (or part thereof) was authorized by the Hologic board of directors. The current Hologic bylaws permit indemnification of officers and directors, but do not require Hologic to provide such persons with indemnification. Hologic has entered into indemnification agreements with each of its current directors and certain of its officers, which provide for mandatory indemnification, and has also agreed to enter into similar indemnification agreements with each of the directors of Cytyc who will become directors of Hologic at the effective time of the merger.

Cytyc Reasons for the Merger

At a meeting held on May 20, 2007, the Cytyc board of directors unanimously determined that the merger agreement and the transactions contemplated by the merger agreement were advisable and fair to and in the best interests of the Cytyc stockholders and approved and adopted the merger agreement and the transactions contemplated thereby, including the merger. In evaluating the merger, the Cytyc board of directors consulted with Cytyc’s management, as well as with Cytyc’s legal and financial advisors. In reaching its conclusion to approve the merger agreement and the transactions contemplated thereby, the Cytyc board of directors considered a variety of factors weighing favorably towards the merger, including, without limitation, the material factors listed below:

| • |  | Strategic Considerations. The Cytyc board of directors considered a number of factors pertaining to the strategic rationale for the merger as supporting its decision to enter into the merger agreement, including the following:

| • |  | the fact that the merger is a combination of two companies that will provide a strong financial base and a diversified product portfolio in the increasingly competitive women’s healthcare marketplace;

| • |  | the complementary aspects of the respective businesses of Cytyc and Hologic, creating the potential for the combined company to be a global leader in women’s healthcare; the combined company will offer a product portfolio that meets many of a woman’s screening and treatment needs throughout her life, including integrated solutions in screening, diagnostics and therapeutics for women’s health, including breast cancer, cervical cancer, menorrhagia, pre-natal health, osteoporosis, endometriosis and permanent contraception;

| • |  | the combined company will be able to offer an expanded product portfolio with over 90% of its total revenue from products that are the leader in market share in the United States;

| • |  | the combined company will have comprehensive sales coverage creating one of the largest sales and service organizations exclusively focused on women’s healthcare in the diagnostic and medical technology industry in the United States with over 900 sales and service professionals in the United States;

| • |  | the combined company will provide significant cross-selling synergies;

| • |  | the combined company will have an enhanced international presence with direct operations in over 20 countries and a commercial presence in over 125 countries worldwide; and

| • |  | the Cytyc board of directors’ belief that the combined company will provide significantly greater capabilities and competitiveness than Cytyc currently has on its own, including:

79

##### Table of Contents

| • |  | greater financial, research and development, and marketing resources to better serve its customers;

| • |  | the acceleration of the introduction of new and improved products and services; and

| • |  | greater ability to develop next-generation products and services.

| • |  | Strategic Alternatives. The Cytyc board of directors considered the strategic alternatives to the merger available to Cytyc, including remaining a stand-alone entity and pursuing acquisitions of strategic assets and alternative acquisition candidates, and the determination of the Cytyc board of directors that a combination with Hologic is expected to yield greater strategic benefits than other reasonably likely alternatives because of the factors described above in “—Strategic Considerations.”

| • |  | Financial Considerations. The Cytyc board of directors considered a number of financial factors pertaining to the merger as supporting its decision to enter into the merger agreement, including the following:

| • |  | the financial performance and condition, business operations and prospects of each of Cytyc, Hologic and the combined company;

| • |  | that Cytyc stockholders will own approximately 55% of the combined company’s outstanding shares immediately after the effective time of the merger (assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024), which will allow Cytyc stockholders to participate in all of the benefits of the combined company, including future growth and expected synergies of the combined company while retaining the flexibility of selling all or a portion of those shares for cash into a very liquid market at any time;

| • |  | the financial terms of the transaction, including the fixed exchange rate of 0.52 of a share of Hologic common stock for each share of Cytyc common stock and the payment of $16.50 in cash per share of Cytyc common stock to be paid in connection with the merger. Based upon Hologic’s closing stock price of $57.61 per share on May 18, 2007 (the last trading day before the merger agreement was announced), the transaction represented a purchase price of $46.46 per share of Cytyc common stock or a 32.5% premium to the Cytyc common stock closing price on May 18, 2007 and representing premiums of 36.9%, 32.2%, 38.2%, 50.1% and 67.0% over the average closing share price during the 15-day, 1-month, 3-month, 6-month and 1-year periods ended May 18, 2007, respectively;

| • |  | the expected merger benefits estimated to be more than $75 million in anticipated synergies primarily from cross-selling opportunities and $25 million in annual cost savings. See “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors” beginning on pages 46 and 25, respectively;

| • |  | the opportunity for Cytyc stockholders to benefit from any increase in the trading of Hologic common stock between announcement of the merger and the closing of the merger;

| • |  | the expectation that the merger would allow the combined company to generate significant cash flows;

| • |  | the expectation that the merger would be accretive to the adjusted earnings per share of the combined company beginning in fiscal year 2008;

| • |  | that the merger is expected to result in a 20% annual revenue growth rate and 20% growth rate in adjusted earnings per share (excluding the write-off and amortization of acquisition-related intangible assets and related tax effect) in future years; and

| • |  | the fact that Hologic has secured fully committed debt financing for the approximately $2.2 billion cash portion of the merger consideration.

80

##### Table of Contents

| • |  | Governance Considerations. The Cytyc board of directors considered a number of governance factors pertaining to the merger as supporting its decision to enter into the merger agreement, including the following:

| • |  | the fact that the board of directors of the combined company would be comprised of eleven directors, including five designees from Cytyc (including the chief executive officer of Cytyc) and six designees from Hologic;

| • |  | the fact that Patrick J. Sullivan will become chairman of the combined company;

| • |  | the fact that, while the combined company’s headquarters would be located in Bedford, Massachusetts, the headquarters of the Cytyc business would continue to be located in Marlborough, Massachusetts; and

| • |  | the strong management team to be drawn from both Cytyc and Hologic that will manage the combined company, the complementary cultural fit and organizational structure of both companies and the demonstrated ability of both management of Cytyc and management of Hologic to integrate and obtain benefits from previous business combinations.

| • |  | Tax Considerations. The Cytyc board of directors considered the ability to complete the merger as a reorganization for U.S. federal income tax purposes with the Cytyc stockholders being taxed on an amount not to exceed the cash portion of the merger consideration that they receive.

| • |  | Opinions of Financial Advisors. The Cytyc board of directors considered Morgan Stanley’s and JPMorgan’s separate opinions, each dated May 20, 2007, to Cytyc’s board of directors as to the fairness, from a financial point of view and as of the date of the opinion, of the merger consideration to be received by Cytyc stockholders pursuant to the merger agreement, as more fully described in “—Opinions of Financial Advisors to the Cytyc Board of Directors” beginning on page 83.

| • |  | Terms of the Merger Agreement. The Cytyc board of directors considered that the terms of the merger agreement are reasonable, including:

| • |  | the merger agreement permits Cytyc to provide material non-public information to, and engage in negotiations with, a third party that makes an acquisition proposal that is or is reasonably likely to lead to a superior proposal (as described in “The Merger Agreement—Certain Covenants—No Solicitation” beginning on page 121), on the terms and subject to the conditions of the merger agreement;

| • |  | the merger agreement provides Cytyc, under certain circumstances, with the ability to terminate the merger agreement in order to enter into an alternative transaction that is deemed by the directors of Cytyc to be a superior proposal;

| • |  | the merger agreement permits the Cytyc board of directors, under certain circumstances, to change its recommendation with respect to the merger in response to a material development or change in circumstances occurring or arising after the date of execution of the merger agreement that was not known to the Cytyc board of directors as of, or prior to, the date of execution of the merger agreement, provided that the change or development is not, and does not result from, a change in the market price of the common stock of Hologic primarily as a result of the announcement of the merger agreement and the transactions contemplated thereby;

| • |  | the circumstances under which the Cytyc termination fees are payable under the merger agreement and the view of the Cytyc board of directors that these provisions should not preclude a bona fide alternative proposal involving Cytyc;

| • |  | the fact that the termination fee provisions are the product of negotiations;

| • |  | the fact that the size of the termination fees are reasonable in light of the size and benefits of the merger;

81

##### Table of Contents

| • |  | the circumstances under which the Hologic termination fees are payable to Cytyc under the merger agreement; and

| • |  | the fact that the representations, warranties and covenants of Cytyc and Hologic are generally reciprocal.

| • |  | Regulatory Approvals. The Cytyc board of directors considered the regulatory approvals required to complete the merger, including expiration or termination of any waiting period or extension thereof under the HSR Act, and the belief of Cytyc’s management that the merger would be approved by the requisite authorities, without the imposition of conditions sufficiently material to preclude or materially diminish the benefits expected from the merger, and would otherwise be completed in accordance with the terms of the merger agreement.

| • |  | Due Diligence. The Cytyc board of directors considered the results of Cytyc’s due diligence review of Hologic.

The Cytyc board of directors weighed the aforementioned material factors against a number of other factors identified in its deliberations that weighted negatively against the merger, including, without limitation, the following material factors:

| • |  | the challenges inherent in the combination of two businesses of the size and scope of Cytyc and Hologic and the possible diversion of management’s attention for an extended period of time;

| • |  | the risk of not capturing all of the anticipated synergies between Cytyc and Hologic and the risk that other anticipated benefits of the merger might not be realized;

| • |  | because the exchange ratio is fixed, in the event of a decrease in the price of Hologic common stock between the date of execution of the merger agreement and the closing of the merger, Cytyc stockholders may receive less value for their shares upon the closing of the merger than calculated pursuant to the exchange ratio on the date of execution of the merger agreement and on the date of the Cytyc special meeting;

| • |  | certain provisions of the merger agreement that could have the effect of discouraging proposals for alternative transactions involving Cytyc, including:

| • |  | the restrictions on Cytyc’s ability to solicit proposals for alternative transactions involving Cytyc; and

| • |  | that Cytyc may be required to pay to Hologic a termination fee of either $50 million or $150 million depending upon the termination event;

| • |  | the fees and expenses associated with completing the merger;

| • |  | the risk that the merger may not be completed despite the parties’ efforts or that the closing may be unduly delayed and the effects on Cytyc as a stand-alone company because of such failure or delay; and

| • |  | the other risks described in “Risk Factors” beginning on page 25.

After consideration of these factors, the Cytyc board of directors determined that these risks could be mitigated or managed by Cytyc or Hologic or by the combined company following the merger, were reasonably acceptable under the circumstances or, in light of the anticipated benefits, the risks were unlikely to have a materially adverse impact on the merger or on the combined company following the merger, and that, overall, these risks were significantly outweighed by the potential benefits of the merger.

Although this discussion of the information and factors considered by the Cytyc board of directors is believed to include the material factors considered by the Cytyc board of directors, it is not intended to be exhaustive and may not include all of the factors considered by the Cytyc board of directors. In reaching its determination to approve and recommend the merger and the merger agreement, the Cytyc board of directors did

82

##### Table of Contents

not quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination that the merger and the merger agreement are advisable and fair to and in the best interests of Cytyc and its stockholders. Rather, the Cytyc board of directors based its position and recommendation on the totality of the information presented to and factors considered by it. In addition, individual members of the Cytyc board of directors may have given differing weights to different factors.

In considering the recommendation of the Cytyc board of directors with respect to the merger and the merger agreement, you should be aware that certain Cytyc directors and officers have arrangements that may cause them to have interests in the transaction that are different from, or are in addition to, the interests of Cytyc stockholders generally. See “—Interests of Cytyc Executive Officers and Directors in the Merger” beginning on page 94.

Recommendations of the Cytyc Board of Directors

The Cytyc board of directors has unanimously determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and fair to and in the best interests of Cytyc and the Cytyc stockholders and unanimously recommends that the Cytyc stockholders vote “FOR” the proposal to adopt the merger agreement and the transactions contemplated thereby, including the merger, and “FOR” the proposal to adjourn the Cytyc special meeting, including, if necessary, to solicit additional proxies in favor of such adoption.

Opinions of Financial Advisors to the Cytyc Board of Directors

Cytyc has retained Morgan Stanley and JPMorgan as its financial advisors in connection with the merger.

On May 20, 2007, at a meeting of the Cytyc board of directors held to evaluate the proposed merger, Morgan Stanley and JPMorgan delivered to the Cytyc board of directors separate oral opinions, which opinions were confirmed by delivery of separate written opinions each dated May 20, 2007, to the effect that, as of that date and based on and subject to various assumptions, matters considered and limitations described in such opinions, the merger consideration to be received by the holders of Cytyc common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders.

Morgan Stanley’s and JPMorgan’s opinions, the full texts of which describe the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Morgan Stanley and JPMorgan, are attached hereto as Annex E and Annex F, respectively, and are incorporated into this joint proxy statement/prospectus by reference. Morgan Stanley’s and JPMorgan’s opinions were directed only to the fairness, from a financial point of view, of the merger consideration provided for in the merger agreement and do not address any other aspect of the merger. The opinions do not address the relative merits of the merger as compared to other business strategies or transactions that might be available with respect to Cytyc or Cytyc’s underlying business decision to effect the merger. The opinions do not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the merger. Holders of Cytyc common stock are encouraged to read the opinions carefully in their entirety. The summaries of Morgan Stanley’s and JPMorgan’s opinions described below are qualified in their entirety by reference to the full texts of the opinions.

Opinion of Morgan Stanley. Cytyc retained Morgan Stanley to provide it with financial advisory services and a financial opinion in connection with a possible merger or sale of Cytyc. Morgan Stanley was selected by Cytyc to act as its financial advisor based on Morgan Stanley’s qualifications, expertise, reputation and its knowledge of the business and affairs of Cytyc. At the special meeting of Cytyc’s board of directors on May 20, 2007, Morgan Stanley rendered its oral opinion, subsequently confirmed in writing, that, as of May 20, 2007, based upon and subject to the various considerations set forth in the opinion, the merger consideration to be received by the holders of the Cytyc common stock pursuant to the merger agreement was fair from a financial point of view to such holders.

Morgan Stanley did not make any independent valuation or appraisal of the assets or liabilities of Cytyc, nor was it furnished with any such appraisals. Morgan Stanley’s opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to it as of the date of the opinion. Events occurring after the date of the opinion may affect Morgan Stanley’s opinion and the assumptions used in preparing it, and Morgan Stanley did not assume any obligation to update, revise or reaffirm its opinion.

In arriving at its opinion, Morgan Stanley was not authorized to solicit, and did not solicit, interest from any party with respect to the acquisition, business combination or other extraordinary transaction, involving Cytyc or any of its assets, nor did Morgan Stanley negotiate with any party other than Hologic.

Summary of Certain Financial Analyses Conducted by Morgan Stanley

The following is a brief summary of the material analyses performed by Morgan Stanley in connection with its opinion dated May 20, 2007. This summary of financial analyses includes information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

Equity Research Analyst Price Targets Analysis

Morgan Stanley reviewed and analyzed future public market trading price targets for Cytyc common stock prepared and published by equity research analysts. These targets reflect each analyst’s estimate of the future public market trading price of Cytyc common stock. Morgan Stanley noted that the range of equity analyst price targets of Cytyc common stock was between $37.00 and $42.00 per share. Morgan Stanley further calculated that using a discount rate of 8.5% and a discount period of one year, the present value of the equity analyst price target range was $34.10 to $38.71.

The public market trading price targets published by securities research analysts do not necessarily reflect current market trading prices for Cytyc common stock and these estimates are subject to uncertainties, including the future financial performance of Cytyc and future financial market conditions.

Comparable Company Analysis

Morgan Stanley compared selected financial information for Cytyc with publicly available information for comparable healthcare companies that shared similar characteristics with Cytyc. The companies used in this comparison included those companies listed below:

| • |  | American Medical Systems Holdings Inc.

| • |  | Gen-Probe Inc.

| • |  | ArthroCare Corp.

| • |  | Ventana Medical Systems Inc.

| • |  | Immucor Inc.

| • |  | Digene Corp.

##### Table of Contents

Based upon IBES consensus estimates for calendar year 2008 earnings per share and long-term growth of earnings per share, and using the closing prices as of May 18, 2007 for shares of the comparable companies listed above, Morgan Stanley calculated the following ratios for each of these companies:

| • |  | the closing stock price divided by the estimated IBES consensus earnings per share for calendar year 2008, referred to below as the P/E Multiple; and

| • |  | the P/E Multiple divided by the estimated IBES consensus long-term growth rate of earnings per share, referred to below as the P/E/G Ratio.

Based on the analysis of the relevant metrics for each of the comparable companies, Morgan Stanley selected representative ranges of P/E Multiples and P/E/G Ratios for the comparable companies and applied these ranges to the relevant Cytyc financial statistic(s) as provided by Cytyc management and publicly available information. Based on this analysis, Morgan Stanley calculated the implied value per share of Cytyc common stock as of May 18, 2007, as follows:

Financial Metric |  | Cytyc Calendar Year 2008 EPS |  | Cytyc IBES Consensus Long-Term Growth |  |  | Comparable Company Multiple Statistics |  | Implied Value Per Share Range for Cytyc
P/E Multiple |  | $ | 1.64 |  | NA |  |  | 20.0x - 28.0x |  | $ | 32.88 - $46.03
P/E/G Ratio |  | $ | 1.64 |  | 17.0 | % |  | 0.7x - 1.0x |  | $ | 19.56 - $27.95

No company included in the comparable company analysis is identical to Cytyc. In evaluating the comparable companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters. Many of these matters are beyond the control of Cytyc, such as the impact of competition on the business of Cytyc and the industry in general, industry growth and the absence of any material adverse change in the financial condition and prospects of Cytyc or the industry or in the financial markets in general. Mathematical analysis, such as determining the arithmetic mean or median, or the high or low, is not in itself a meaningful method of using comparable company data.

Analysis of Precedent Transactions

Morgan Stanley compared the premia paid in 57 selected transactions from January 1, 2002 through May 16, 2007 in which the target company was a U.S. based company and was publicly traded. The following table summarizes Morgan Stanley’s analysis:

Precedent Transactions Premia |  | Premium to 1-Day Prior Price |  | Premium to 4-Weeks Prior Price
Mean |  | 19.5% |  | 25.6%
Median |  | 15.6% |  | 24.5%
High |  | 75.4% |  | 74.8%
Low |  | (4.6)% |  | (1.2)%
Representative Range |  | 10.0% - 30.0% |  | 25.0% - 40.0%
Implied Value per Share |  | $38.56 - $45.57 |  | $43.85 - $49.11

Discounted Cash Flow Analysis

Morgan Stanley calculated ranges of implied equity values per share for Cytyc, based on discounted cash flow analyses utilizing Cytyc management projections for the calendar years 2007 through 2017. In arriving at the estimated equity values per share of Cytyc common stock, Morgan Stanley calculated a terminal value as of December 31, 2017 by applying a range of perpetual free cash flow growth rates ranging from 1.0% to 3.0%. The unlevered free cash flows from calendar years 2007 through 2017 and the terminal value were then discounted to present values using a range of discount rates from 8.0% to 9.0%. Based on the calculations set forth above, this analysis implied a range for Cytyc common stock of $33.10 to $45.42 per share.

86

##### Table of Contents

Morgan Stanley also calculated ranges of implied value per share to be received by Cytyc stockholders in exchange for their Cytyc common stock in the form of shares of the pro forma combined entity plus cash consideration per share. This calculation was based on a discounted cash flow analysis utilizing Cytyc’s management projections discussed above, and projections relating to Hologic prepared by Cytyc management for the fiscal years 2007 through 2017, each ending September 30. In calculating the implied value per share to be received by Cytyc stockholders in exchange for their Cytyc common stock in the form of shares of the pro forma combined entity plus cash consideration, Morgan Stanley calculated a terminal value as of September 30, 2017 by applying a range of perpetual free cash flow growth rates from 2.5% to 3.5%. The pro forma unlevered free cash flows from fiscal years 2007 through 2017 and the terminal value were then discounted to present values using a range of discount rates from 8.0% to 9.0%. Morgan Stanley noted the range of implied value per share to be received by Cytyc stockholders assuming the 0.52 exchange ratio plus $16.50 in cash per share of Cytyc common stock was $38.96 to $50.24.

Morgan Stanley also noted the range of implied value per share to be received by Cytyc stockholders in exchange for their Cytyc common stock when including cost synergies from the merger as estimated by Cytyc management, plus $16.50 in cash per share of Cytyc common stock, was $40.00 to $51.67.

Morgan Stanley also noted that the range of implied value per share to be received by Cytyc stockholders in exchange for their Cytyc common stock when including revenue and cost synergies from the merger as estimated by Cytyc management, plus $16.50 in cash per share of Cytyc common stock, was $41.80 to $54.12.

In connection with the review of the merger by Cytyc’s board of directors, Morgan Stanley performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley’s view of the actual value of Cytyc. In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters. Many of these assumptions are beyond the control of Cytyc. Any estimates contained in Morgan Stanley’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness of the merger consideration pursuant to the merger agreement from a financial point of view to holders of shares of Cytyc common stock and in connection with the delivery of its opinion to Cytyc’s board of directors. These analyses do not purport to be appraisals or to reflect the prices at which shares of common stock of Cytyc might actually trade.

The merger consideration was determined through arm’s-length negotiations between Cytyc and Hologic and was approved by Cytyc ‘s board of directors. Morgan Stanley provided advice to Cytyc during these negotiations. Morgan Stanley did not, however, recommend any specific merger consideration to Cytyc or that any specific merger consideration constituted the only appropriate merger consideration for the merger.

Morgan Stanley’s opinion and its presentation to Cytyc’s board of directors was one of many factors taken into consideration by Cytyc’s board of directors in deciding to approve, adopt and authorize the merger agreement. Consequently, the analyses as described above should not be viewed as determinative of the opinion of Cytyc’s board of directors with respect to the merger consideration or of whether Cytyc’s board of directors would have been willing to agree to a different merger consideration.

At the meeting of the Cytyc board of directors on May 20, 2007, JPMorgan rendered its oral opinion, subsequently confirmed in writing, to the Cytyc board of directors to the effect that, as of that date and based upon and subject to the matters set forth in JPMorgan’s opinion, the merger consideration to be received by holders of Cytyc common stock in the merger was fair, from a financial point of view, to those holders.

##### Table of Contents

| • |  | reviewed certain internal financial analyses and forecasts prepared by Cytyc management relating to the businesses of Cytyc and Hologic, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the merger, which are referred to below as the synergies; and

| • |  | performed other financial studies and considered other information as JPMorgan deemed appropriate for the purposes of its opinion.

JPMorgan also held discussions with certain members of Cytyc management and Hologic management with respect to certain aspects of the merger, the past and current business operations of Cytyc and Hologic, the financial condition and future prospects and operations of Cytyc and Hologic, the effects of the merger on the financial condition and future prospects of Cytyc and Hologic, and certain other matters that JPMorgan believed necessary or appropriate to its inquiry.

In giving its opinion, JPMorgan relied upon and assumed, without assuming responsibility or liability for independent verification, the accuracy and completeness of all information that was publicly available or was furnished to or discussed with JPMorgan by Cytyc and Hologic or otherwise reviewed by or for JPMorgan. JPMorgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities, nor did JPMorgan evaluate the solvency of Cytyc or Hologic under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to JPMorgan, including the synergies, JPMorgan assumed that they were reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by Cytyc management as to the expected future results of operations and financial condition of Cytyc and Hologic to which those analyses or forecasts relate. JPMorgan expressed no view as to those analyses or forecasts, including the synergies, or the assumptions on which they were based. JPMorgan also assumed that the merger will qualify as a tax-free reorganization for United States federal income tax purposes, and that the other transactions contemplated by the merger agreement will be completed as described in the merger agreement. JPMorgan also assumed that the representations and warranties made by Cytyc and Hologic in the merger agreement and the related agreements will be true and correct in all ways material to JPMorgan’s analysis. JPMorgan relied as to all legal, regulatory and tax matters relevant to the rendering of its opinion upon the advice of advisors to Cytyc. JPMorgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the completion of the merger will be obtained without any adverse effect on Cytyc, Hologic or on the contemplated benefits of the merger.

JPMorgan’s opinion was based on economic, market and other conditions as in effect on, and the information made available to JPMorgan as of, the date of its opinion. Subsequent developments may affect the opinion, and JPMorgan does not have any obligation to update, revise or reaffirm its opinion. JPMorgan’s opinion was limited to the fairness, from a financial point of view, of the consideration to be received by holders of Cytyc common stock in the merger, and JPMorgan expressed no opinion as to the fairness of the merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of Cytyc or as to the underlying decision by Cytyc to engage in the merger. JPMorgan expressed no opinion as to the price at which Cytyc common stock or Hologic common stock will trade at any future time.

JPMorgan was not requested to and did not provide advice concerning the structure, the specific amount of the merger consideration, or any other aspects of the merger, or to provide services other than the delivery of its opinion. JPMorgan was not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of Cytyc or any other alternative transaction, and did not participate in negotiations with respect to the terms of the merger and related transactions.

In accordance with customary investment banking practice, JPMorgan employed generally accepted valuation methods in reaching its opinion. The following is a summary of the material financial analyses utilized by JPMorgan in connection with providing its opinion. The financial analyses summarized below include

information presented in tabular format. In order to fully understand JPMorgan’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data described below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of JPMorgan’s financial analyses.

Transaction Overview

Based upon the closing price per share of Hologic common stock of $57.61 on May 18, 2007, which was the last trading day prior to the public announcement of the merger, the exchange ratio of 0.52 of a share of Hologic common stock per share of Cytyc common stock, and the cash consideration of $16.50 per share of Cytyc common stock, JPMorgan noted that the implied value of the merger consideration pursuant to the merger as of May 18, 2007 was $46.46 per share of Cytyc common stock. JPMorgan also noted that the implied merger consideration of $46.46 per share of Cytyc common stock represented:

| • |  | a premium of 32.5% over the closing price per share of Cytyc common stock on May 18, 2007 of $35.05;

Selected Companies Analysis. Using publicly available information and information provided by Cytyc management, JPMorgan compared selected financial data of Cytyc with similar data for the group of companies listed above under “- Historical Share Price Analysis.” In its analysis, JPMorgan derived and compared multiples for Cytyc and the selected companies, calculated as follows:

| • |  | the price per share divided by estimated earnings per share, or EPS, for calendar year 2007, which is referred to below as “2007E P/E”; and

| • |  | the price per share divided by the product obtained by multiplying estimated EPS for calendar year 2007 by the estimated long-term earnings per share growth rate, which is referred to below as “2007E PEG.”

This analysis indicated the following:

2007E P/E |  | 39.2x |  | 28.0x
2007E PEG |  | 1.68x |  | 1.10x

Using a reference range of 25.0x to 33.0x Cytyc’s 2007E EPS and 1.20x to 1.70x Cytyc’s 2007E PEG, JPMorgan determined a range of implied equity values for Cytyc. This analysis indicated a range of implied values per share of Cytyc common stock of approximately $33.00 to $43.50 using Cytyc’s 2007E EPS and $27.00 to $38.25 using Cytyc’s 2007E PEG, compared in each case to the closing price per share of Cytyc common stock of $35.05 on May 18, 2007 and the implied merger consideration of $46.46 per share of Cytyc common stock.

It should be noted that no company utilized in the analysis above is identical to Cytyc.

Benchmark |  | High |  | Low |  | Mean |  | Median
Firm Value/LTM EBITDA |  | 27.3x |  | 11.2x |  | 16.7x |  | 15.1x

Using a reference range of 15.0x to 20.0x Cytyc’s LTM EBITDA, JPMorgan determined a range of implied enterprise values for Cytyc, which were then adjusted for Cytyc’s cash and total debt as of March 31, 2007 to determine a range of implied equity values. This analysis indicated a range of implied values per share of Cytyc common stock of approximately $34.25 to $44.75, compared to the closing price per share of Cytyc common stock of $35.05 on May 18, 2007 and the implied merger consideration of $46.46 per share of Cytyc common stock.

It should be noted that no company utilized in the analysis above is identical to Cytyc and no transaction is identical to the merger.

Discounted Cash Flow Analysis. JPMorgan conducted a discounted cash flow analysis for the purpose of determining the implied fully diluted equity value per share for Cytyc common stock on a standalone basis without giving effect to the proposed merger or any potential synergies, using financial forecasts prepared by Cytyc management for the fiscal years 2007 through 2017. JPMorgan calculated the unlevered free cash flows that Cytyc is expected to generate during fiscal years 2007 through 2017. JPMorgan then calculated an implied range of terminal values for Cytyc using a range of perpetuity growth rates for free cash flows from 2.5% to 3.5% and a range of discount rates from 8.5% to 9.5%. The unlevered free cash flows and the range of terminal values were then discounted to present value using a range of discount rates from 8.5% to 9.5%. The present value of the unlevered free cash flows and the range of terminal values were then adjusted for Cytyc’s cash and total debt as of March 31, 2007. This analysis indicated a range of implied values per share of Cytyc common stock of approximately $34.00 to $43.75, compared to the closing price per share of Cytyc common stock of $35.05 on May 18, 2007 and the implied merger consideration of $46.46 per share of Cytyc common stock.

Selected Companies Analysis. Using publicly available information and information provided by Cytyc management, JPMorgan compared selected financial data of Hologic with similar data for the group of companies listed above under “Historical Share Price Analysis.” In its analysis, JPMorgan derived and compared multiples for Hologic and the selected companies, calculated as follows:

| • |  | the price per share divided by estimated EPS for calendar year 2008, which is referred to below as “2008E P/E”; and

| • |  | the price per share divided by the product obtained by multiplying estimated EPS for calendar year 2008 by the estimated long-term earnings per share growth rate, which is referred to below as “2008E PEG.”

This analysis indicated the following:

2008E P/E |  | 34.9x |  | 19.2x
2008E PEG |  | 1.29x |  | 0.76x

Using a reference range of 26.0x to 33.0x Hologic’s 2008E EPS and 0.75x to 1.00x Hologic’s 2008E PEG, JPMorgan determined a range of implied equity values for Hologic. This analysis indicated a range of implied values per share of Hologic common stock of approximately $57.00 to $72.25 using Hologic’s 2008E EPS and $57.50 to $76.50 using Hologic’s 2008E PEG, compared to the closing price per share of Hologic common stock of $57.61 on May 18, 2007.

It should be noted that no company utilized in the analysis above is identical to Hologic.

Discounted Cash Flow Analysis. JPMorgan conducted a discounted cash flow analysis for the purpose of determining the implied fully diluted equity value per share for Hologic common stock on a standalone basis without giving effect to the proposed merger or any potential synergies, using financial forecasts prepared by Hologic management as adjusted by Cytyc management for the fiscal years 2007 through 2017.

JPMorgan calculated the unlevered free cash flows that Hologic is expected to generate during fiscal years 2007 through 2017. JPMorgan calculated an implied range of terminal values for Hologic using a range of perpetuity growth rates for free cash flows from 3.0% to 4.0% and a range of discount rates from 8.5% to 9.5%. The unlevered free cash flows and the range of terminal values were then discounted to present value using a range of discount rates from 8.5% to 9.5%. The present value of the unlevered free cash flows and the range of terminal values were then adjusted for Hologic’s cash and total debt as of March 31, 2007. This analysis indicated a range of implied values per share of Hologic common stock of approximately $49.50 to $66.75, compared to the closing price per share of Hologic common stock of $57.61 on May 18, 2007.

Pro Forma Analysis. JPMorgan analyzed the potential pro forma impact of the merger on Hologic’s pro forma earnings per share on a cash basis, which excludes the estimated impact of the amortization of identifiable intangibles relating to Hologic’s acquisition of Cytyc, and on a GAAP basis. In this analysis, 2008 and 2009 earnings projections for Hologic were based on earnings projections prepared by Hologic management as adjusted by Cytyc management, and earnings projections for Cytyc were prepared by Cytyc management. JPMorgan assumed for purposes of this analysis that the merger would close on September 30, 2007.

Based on this analysis, JPMorgan observed that the merger would result in earnings per share accretion for Hologic stockholders on a cash basis and excluding synergies of 4.0% and 17.1% for 2008 and 2009, respectively, and earnings per share accretion for Hologic stockholders on a cash basis and including synergies of 9.9% and 23.3% for 2008 and 2009, respectively. JPMorgan also observed that the merger would result in

earnings per share dilution for Hologic stockholders on a GAAP basis and excluding synergies of 21.2% and 4.4% for 2008 and 2009, respectively, and earnings per share dilution for Hologic stockholders on a GAAP basis and including synergies of 14.8% for 2008 and earnings per share accretion on a GAAP basis and including synergies of 2.2% for 2009.

The summary set forth above does not purport to be a complete description of the analyses or data utilized by JPMorgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. JPMorgan believes that the summary set forth above and its analyses must be considered as a whole and that selecting portions thereof, without considering all of its analyses, could create an incomplete view of the processes underlying its analyses and opinion. JPMorgan based its analyses on assumptions that it deemed reasonable, including assumptions concerning general business and economic conditions and industry-specific factors. The other principal assumptions upon which JPMorgan based its analyses are set forth above under the description of each analysis. JPMorgan’s analyses are not necessarily indicative of actual values or actual future results that might be achieved, which values may be higher or lower than those indicated. Moreover, JPMorgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold.

As a part of its investment banking business, JPMorgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. JPMorgan was selected to deliver an opinion to the Cytyc board of directors with respect to the merger on the basis of JPMorgan’s experience and its familiarity with Cytyc.

For services rendered, Cytyc agreed to pay JPMorgan a fee of $4.0 million payable upon delivery of its opinion. In addition, Cytyc has agreed to reimburse JPMorgan for its reasonable expenses incurred in connection with its services, including reasonable fees of outside counsel, and will indemnify JPMorgan against certain liabilities, including liabilities arising under federal securities laws.

In addition, JPMorgan and its affiliates maintain commercial and investment banking and other business relationships with Cytyc, Hologic and their respective affiliates, for which it receives customary fees. In the ordinary course of their businesses, JPMorgan and its affiliates may actively trade the debt and equity securities of Cytyc or Hologic for their own accounts or for the accounts of customers and, accordingly, they may at any time hold long or short positions in those securities. In addition, JPMorgan served as financial advisor to Cytyc in connection with its acquisition of Adeza Biomedical Corporation in 2007 and as financial advisor to Hologic in connection with its acquisition of R2 Technology, Inc. in 2006. After JPMorgan delivered its opinion to the Cytyc board of directors and the merger agreement was entered into, JPMorgan and one of its affiliates became parties to an amended and restated commitment letter with Hologic to provide a portion of the financing required by Hologic in connection with the merger, for which JPMorgan and such affiliate would expect to receive compensation.

Interests of Cytyc Executive Officers and Directors in the Merger

In considering the recommendation of the Cytyc board of directors with respect to the merger, Cytyc stockholders should be aware that executive officers of Cytyc and members of the Cytyc board of directors may have interests in the transactions contemplated by the merger agreement that are different from, or in addition to, the interests of the Cytyc stockholders generally. The Cytyc board of directors was aware of these interests and considered them, among other matters, in approving the merger agreement and making its recommendation. These interests are summarized below.

Board and Committee Composition of Hologic After the Merger. The following summarizes certain changes that will take effect at the effective time of the merger. At the effective time of the merger, the board of

At the effective time of the merger, each of the audit committee, the nominating and corporate governance committee and the corporate development committee of the board of directors of Hologic will be comprised of an odd number of directors, consisting of one more continuing Hologic director than continuing Cytyc directors. The chairman of each of these committees will be a continuing Hologic director. In addition, at the effective time of the merger, the compensation committee of the board of directors of Hologic will be comprised of an even number of directors, consisting of an equal number of continuing Cytyc directors and continuing Hologic directors. The chairman of the compensation committee will be a continuing Cytyc director. See “—Board of Directors and Management of Hologic Following the Merger; Headquarters” beginning on page 104.

| • |  | outplacement services the scope and provisions of which will be at the highest level provided by Cytyc to peer employees.

In the event that any payment by Cytyc to an executive officer in connection with a change of control would be subject to the excise tax imposed under Section 4999 of the Code, Cytyc will be obligated to make whole the executive officer with respect to such excise tax.

An executive officer’s receipt of severance benefits pursuant to a change of control agreement is subject to the following conditions: (i) execution of a general release of Cytyc by the executive officer; (ii) presentation of satisfactory evidence that the executive has returned all of Cytyc’s company property, confidential information and documentation to Cytyc; (iii) compliance with the provisions of the confidentiality agreement and non-competition agreement that the executive officer has entered into with Cytyc; and (iv) submission to Cytyc of a signed written resignation of the executive officer’s status as an officer and/or director of Cytyc or of any of Cytyc’s affiliates, if applicable.

Amendment to Change of Control Agreements.

(1) | Consists of estimated payments of base salary and bonus due at the closing of the merger as a result of a change of control event pursuant to each executive officer’s existing change of control agreement, as amended, with Cytyc. Estimated payments were calculated using each executive officer’s salary and bonus information as of June 22, 2007. Due to the structure of the merger, Cytyc does not believe these payments would be “excess parachute payments” under Section 280G of the Code and therefore would not be subject to the excise tax imposed under Section 4999 of the Code.

(2) | Each of Patrick J. Sullivan and Daniel J. Levangie has entered into a retention and severance agreement with Hologic. One-half of the amount set forth above consists of a cash retention bonus and the other one-half consists of the value of Hologic restricted stock units to be received by each of Messrs. Sullivan and Levangie, subject to the terms and conditions (including continued employment with Hologic) set forth in the retention and severance agreements. Under the retention and severance agreements, Messrs. Sullivan and Levangie may receive additional benefits if their employment with Hologic is terminated. The retention and severance agreements are described in this joint proxy statement/prospectus under “—Employment Arrangements with Hologic—Hologic Retention and Severance Agreements.”

(3) | Hologic has agreed to offer positions with Hologic or the surviving corporation after the completion of the merger to the executive officer listed above and has provided a term sheet to each such executive officer that establishes the basic terms and conditions of such executive officer’s employment thereafter. The amount set forth above consists of the cash retention bonus provided for in the term sheet, subject to the terms and conditions (including continued employment with Hologic or the surviving corporation) set forth in the term sheet. Under the term sheet, the executive officer may receive additional benefits if his or her employment with Hologic or the surviving corporation is terminated. The term sheets are described in this joint proxy statement/prospectus under “—Employment Arrangements with Hologic—Term Sheets with Certain Other Executives.”

Employment Arrangements with Hologic. In connection with the merger, Hologic has agreed to employ each of Patrick J. Sullivan, current chairman, chief executive officer and president of Cytyc, and Daniel J. Levangie, current executive vice president of Cytyc and president of Cytyc surgical products, as of the effective time of the merger. Mr. Sullivan will be employed as chairman and an executive officer of Hologic and will receive an annual salary of $700,000. Mr. Levangie will be employed as president of Cytyc surgical products which, as of the effective time of the merger, will be a division of Hologic, and will receive an annual salary of $425,000. For the employment period through December 31, 2007, Messrs. Sullivan and Levangie will be eligible for annual bonus awards as determined in accordance with Cytyc’s executive incentive plan. Effective January 1, 2008, Mr. Sullivan will be eligible to receive an annual bonus of up to 150% of his base salary and Mr. Levangie will be eligible to receive an annual bonus of 50% - 100% of his base salary, in each case subject to the terms and conditions of Hologic’s executive bonus plan.

##### Table of Contents

In addition, in connection with entering into the merger agreement, Hologic entered into a retention and severance agreement and a change of control agreement with each of Messrs. Sullivan and Levangie, which would become effective upon and are subject to the completion of the merger.

Hologic Change of Control Agreements. Each change of control agreement of Hologic provides that 30 days after a change of control, Hologic will pay the executive a lump sum in cash equal to three times the executive’s annual salary for the fiscal year immediately preceding the change of control plus the executive’s highest annual bonus (as defined in the change of control agreements). In addition, the change of control agreements provide that, notwithstanding any provision to the contrary contained in any option, restricted stock agreement or other equity compensation agreement or plan, upon a change of control, all unvested stock options, restricted stock or stock appreciation rights held by the executive will become immediately exercisable for a one-year period following the executive’s termination date. The change of control agreements confer no benefits prior to a change of control.

In the event that any payments received by the executive in connection with a change of control are subject to the excise tax imposed upon certain change of control payments under federal tax laws, the agreements provide that Hologic’s auditing firm immediately preceding the change of control will compute the excise tax imposed on the executive and Hologic will pay that amount to the executive to provide the executive with a payment that is economically equivalent to the payment he would have received but for the imposition of the excise tax.

Under the terms of the change of control agreements, if the executive remains employed through the one-year anniversary of a change of control, then the executive will also receive a special bonus (the “Special Bonus”) equal to the sum of the executive’s annual salary and the greater of the annual bonus (as defined in the change of control agreement) paid or payable for the most recently completed fiscal year during the employment period or the highest annual bonus. In addition, if termination of an executive’s employment occurs within the two-year period following a change of control of Hologic and such termination is by Hologic (or its successor) other than for cause or by the executive for good reason, then the executive will be entitled to receive, among other things: (i) all accrued and unpaid compensation; (ii) the Special Bonus, to the extent not previously paid or accrued; and (iii) continued welfare benefits for a period of one year. In addition, such executive’s life insurance policy will be transferred to him.

Hologic Retention and Severance Agreements. Each retention and severance agreement provides that the executive will be paid a retention bonus ($1,500,000 in the case of Mr. Sullivan and $1,000,000 in the case of Mr. Levangie) on the date that is two years after the date of closing of the merger (the retention date) if such executive is continuously employed by Hologic in the capacity specified in the retention and severance agreement during that time. Subject to the exceptions set forth in the following paragraph and as more fully set forth in the retention and severance agreement, the retention bonus will not be paid to the executive in the event he ceases to serve in the specified capacity prior to the retention date for any reason, including, without limitation, his death, disability, resignation or termination of his employment by Hologic for any reason. In addition, on the effective date of the retention and severance agreement, Hologic will issue to the executive the specified amount of restricted stock units ($1,500,000 in the case of Mr. Sullivan and $500,000 in the case of Mr. Levangie) based upon the fair market value of Hologic common stock. These restricted stock units are subject to the terms and conditions of the applicable restricted stock unit agreement.

However, if the executive is terminated without cause or if the executive notifies Hologic that he has been assigned duties that are inconsistent with the duties typically assigned to other executive officers of Hologic in similar positions (in the event there are no Hologic officers serving in similar positions, then to officers at comparable public companies), and Hologic fails to cure such occurrence within the time period set forth in the agreement, then the executive will be paid the applicable retention bonus and all restricted stock units will immediately and irrevocably vest within fifteen days of such termination.

In consideration for the benefits provided under the retention and severance agreement, each executive has agreed to execute Hologic’s intellectual property rights and non-competition agreement.

101

##### Table of Contents

If the executive’s employment is terminated during the term of the retention and severance agreement, then the executive will be entitled to the following compensation and benefits:

| • |  | If the executive’s employment is terminated (i) by Hologic for cause or disability, (ii) by reason of the executive’s death or (iii) by the executive other than for good reason, then Hologic will pay to the executive accrued compensation only;

| • |  | If the executive’s employment is terminated by Hologic without cause or by the executive for good reason, then the executive will be entitled to each and all of the following:

| • |  | all accrued compensation;

| • |  | a pro rata bonus;

| • |  | a lump sum equal to the executive base salary plus bonus amount;

| • |  | continued medical and dental benefits on the same terms and conditions provided to other executives of Hologic for a period of one year from the date of termination; and

| • |  | out-placement services provided by Crenshaw Associates, Inc. or comparable search firm or, in the alternative, reimburse the executive with $50,000.

In the event that any payment by Hologic to the executive under the retention and severance agreement would be subject to the excise tax imposed upon certain change of control payments under federal tax laws, the payments will be reduced if and to the extent necessary so that no such payment will be subject to the excise tax.

Term Sheets with Certain Other Executives. Hologic has agreed to offer positions with Hologic or the surviving corporation after the completion of the merger to certain officers and vice presidents of Cytyc. These officers include all of the executive officers of Cytyc. Hologic has provided each officer with term sheets that establish the basic terms and conditions of each officer’s employment thereafter. The main provisions of the term sheets are summarized below.

Each term sheet provides that the executive will continue his or her existing salary and will be eligible for a bonus determined in accordance with the Cytyc Executive Incentive Plan, which plan will remain in force until December 31, 2007. The term sheet also contains certain restrictive covenants applicable to the executive, including noncompetition and nonsolicitation restrictions.

Each term sheet provides for a retention bonus. Senior vice presidents will receive a retention bonus in an amount equal to such executive officer’s base salary determined as of the date of execution of merger agreement, which will be paid out as follows: 67% on the twelve month anniversary of the closing date of the merger and 33% on the eighteen month anniversary of the closing date of the merger. Vice presidents will receive a retention bonus in an amount equal to the executive officer’s annual base salary determined as of the date of execution of merger agreement on the twelve month anniversary of the closing date of the merger. In addition, certain vice presidents are eligible to receive an additional one-time incentive bonus of up to $100,000 subject to satisfaction of performance objectives.

102

##### Table of Contents

If Hologic terminates the executive without cause or the executive resigns for good reason, then Hologic will pay to the executive:

| • |  | all accrued obligations;

| • |  | if the executive is a senior vice president and

| • |  | if the termination or resignation occurs prior to the twelve month anniversary of the closing date of the merger, then the remaining balance of the executive’s retention bonus; or

| • |  | if the termination or resignation occurs after the twelve month anniversary of the closing date of the merger, but prior to the eighteen month anniversary of the closing date of the merger, then the remaining balance of the executive’s retention bonus plus six months severance; or

| • |  | if the termination or resignation occurs after the eighteen month anniversary of the closing date of the merger, then severance in accordance with Hologic’s policies;

| • |  | if the executive is a vice president and

| • |  | if the termination or resignation occurs prior to the twelve month anniversary of the closing date of the merger, then the retention bonus plus six months salary continuation; or

| • |  | if the termination or resignation occurs after the twelve month anniversary of the closing date of the merger, then severance in accordance with Hologic’s policies; and

| • |  | any other amounts or benefits required to be paid or provided that the executive is eligible to receive under any plan, program, policy or practice, contract or agreement of Hologic.

In addition, Hologic, at its sole expense, will provide the executive with outplacement services the scope and provider of which will be at the highest level provided by Hologic to its peer employees.

Cytyc Employee Stock Purchase Plan. Under the Cytyc Employee Stock Purchase Plan, or Cytyc ESPP, employees of Cytyc and its subsidiaries are eligible to purchase Cytyc common stock at a price equal to the lesser of 85% of the average market price of Cytyc common stock on the first business day of the payment period and 85% of the average market price of Cytyc common stock on the last business day of the payment period. Each employee may purchase annually up to $25,000 of Cytyc common stock under this plan. Typically, Cytyc common stock is purchased under this plan on the last trading date of any ordinary pay period for employees of Cytyc and its subsidiaries. Under the terms of the merger agreement, each Cytyc ESPP participant’s outstanding right to purchase shares of Cytyc common stock under the Cytyc ESPP will terminate on the day immediately prior to the effective time of the merger. All amounts allocated to each participant’s account as of that date will be used to purchase from Cytyc whole shares of Cytyc common stock at the applicable price determined under the terms of the Cytyc ESPP. The Cytyc ESPP will terminate immediately following these purchases of Cytyc common stock.

Insurance and Indemnification. The merger agreement provides that, following the merger, Hologic will cause the surviving corporation to assume the obligations with respect to indemnification and exculpation from liabilities, including advancement of expenses, for acts and omissions occurring at or prior to the effective time of the merger now existing in favor of all past and present officers and directors of Cytyc or its subsidiaries to the same extent as provided under Cytyc’s certificate of incorporation, bylaws or any indemnification contract between such individuals and Cytyc in effect as of the date of the merger agreement, without further action, as of the effective time of the merger and such obligations will survive the merger and will continue in full force and effect in accordance with their terms. Hologic also will continue to maintain for a period of six years after the completion of the merger, policies of directors’ and officers’ liability insurance with respect to claims arising from acts or omissions occurring prior to the completion of the merger on terms with respect to coverage and amounts no less favorable than the terms of the directors’ and officers’ liability insurance policies maintained by Cytyc prior to the completion of the merger, but in no event will Hologic be required to pay in any one year an

103

##### Table of Contents

amount in excess of 200% of the annual premiums paid by Cytyc for such insurance in the last full fiscal year. In the event such coverage cannot be obtained for such amount or less in the aggregate, Hologic will only be obligated to provide such coverage as may be obtained for such aggregate amount.

Accounting Treatment

The merger will be accounted for using the purchase method of accounting under U.S. GAAP. Under the purchase method of accounting, Hologic will be considered the acquirer of Cytyc for accounting purposes and the total purchase price will be allocated to the assets acquired and liabilities assumed from Cytyc based on their fair values as of the date of the completion of the merger and any excess of purchase price over those fair values will be recorded as goodwill. Reported financial condition and results of operations of Hologic issued after completion of the merger will reflect Cytyc’s balances and results after completion of the merger, but will not be restated retroactively to reflect the historical financial position or results of operations of Cytyc. Following the completion of the merger, the earnings of the combined company will reflect purchase accounting adjustments, including increased amortization and other expense for acquired tangible and intangible assets. For further discussion of the accounting treatment, please see “Unaudited Pro Forma Condensed Combined Financial Information” commencing on page 174.

Federal Securities Laws Consequences; Stock Transfer Restriction Agreements

All shares of Hologic common stock that Cytyc stockholders receive in the merger will be freely transferable, except for shares of Hologic common stock received by persons who are deemed to be “affiliates” of Cytyc under the Securities Act of 1933, as amended, and the related SEC rules and regulations (the “Securities Act”), at the time of the Cytyc special meeting. These “affiliates” may resell their shares of Hologic common stock only in transactions permitted by Rule 145 under the Securities Act or as otherwise allowed under that Act. Persons who may be deemed to be affiliates of Cytyc for these purposes generally include individuals or entities that control, are controlled by, or are under common control with Cytyc and may include some officers, directors and principal stockholders of Cytyc. The merger agreement requires Cytyc to use commercially reasonable efforts to deliver or cause to be delivered from affiliates of Cytyc to Hologic on or before the effective time of the merger an executed letter agreement to the effect that those persons will not offer, sell or otherwise dispose of any shares of Hologic common stock issued to them in the merger in violation of the Securities Act or the related SEC rules and regulations.

Under Rule 145 of the Securities Act, former Cytyc stockholders who are affiliates of Cytyc at the time of the Cytyc special meeting and who are not affiliates of Hologic after completion of the merger, may sell their Hologic common stock at any time subject to the volume and manner of sale limitations and the current public information requirements of Rule 144 under the Securities Act. Further, so long as such former Cytyc affiliates are not considered affiliates of Hologic following completion of the merger, and a period of at least one year has elapsed from completion of the merger, such former affiliates may sell their Hologic common stock without regard to the volume and manner of sale limitations of Rule 144 under the Securities Act so long as there is adequate current public information available about Hologic in accordance with Rule 144 under the Securities Act. After a period of two years has elapsed from the completion of the merger, and so long as such former

105

##### Table of Contents

affiliates are not, and have not been, for at least three months prior to such sale, affiliates of Hologic, such former affiliates may freely sell their Hologic common stock. Former Cytyc stockholders who become affiliates of Hologic after completion of the merger will be subject to the volume and manner of sale limitations and the current public information requirements of Rule 144 under the Securities Act until each such stockholder is no longer an affiliate of Hologic.

This joint proxy statement/prospectus does not cover any resales of the shares of Hologic common stock to be received by Cytyc stockholders upon completion of the merger, and no person is authorized to make any use of this joint proxy statement/prospectus in connection with a resale.

Appraisal Rights

Cytyc Stockholders. If the merger is completed, record holders of Cytyc common stock who comply with the procedures summarized below will be entitled to appraisal rights. Under Section 262 of the DGCL as a result of completion of the merger, holders of shares of Cytyc common stock with respect to which appraisal rights are properly demanded and perfected and not withdrawn or lost are entitled to have the “fair value” of their shares at the effective time of the merger (exclusive of any element of value arising from the accomplishment or expectation of the merger) judicially determined and paid to them in cash by complying with the provisions of Section 262. Cytyc is required to send a notice to that effect to each stockholder not less than 20 days prior to the special meeting. This joint proxy statement/prospectus constitutes that notice to you. The following summary does not constitute any legal or other advice, nor does it constitute a recommendation that Cytyc stockholders exercise their right of appraisal under Section 262. The following is a brief summary of Section 262, which sets forth the procedures for demanding statutory appraisal rights. This summary is not a complete statement of the law pertaining to appraisal rights under Section 262 and is qualified in its entirety by reference to Section 262, a copy of the text of which is attached hereto as Annex G. The statutory right of appraisal granted by Section 262 requires strict compliance with the procedures in Section 262. Failure to follow any of these procedures may result in a termination or waiver of appraisal rights under Section 262.

Cytyc stockholders of record who desire to exercise their appraisal rights must satisfy all of the following conditions.

A Cytyc stockholder of record who desires to exercise appraisal rights must: (i) not vote in favor of the adoption of merger agreement; (ii) deliver a written demand for appraisal of his or her shares of Cytyc common stock to the secretary of Cytyc before the vote on the merger at Cytyc the special meeting; (iii) hold of record his or her shares of Cytyc common stock on the date the written demand for appraisal is made and must continuously hold his or her shares of Cytyc common stock through the effective time of the merger; and (iv) strictly comply with the procedures set forth in Section 262.

A demand for appraisal must be executed fully and correctly, by or for the stockholder of record, as such stockholder’s name appears on the certificates representing shares, or if the shares are held as direct registration shares, as such stockholder’s name appears on the books and records of the transfer agent as the owner of shares. If shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, such demand must be executed by the fiduciary. If shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, such demand must be executed by all joint owners. An authorized agent, including an agent of two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner and expressly disclose that, in exercising the demand, he is acting as agent for the record owner.

A record owner, such as a broker, who holds shares as a nominee for others may exercise appraisal rights with respect to the shares held for all or less than all beneficial owners of shares as to which the holder is the record owner. In such case the written demand must set forth the number of shares covered by such demand.

106

##### Table of Contents

Where the number of shares is not expressly stated, the demand will be presumed to cover all shares outstanding in the name of such record owner.

Beneficial owners who are not record owners and who intend to exercise appraisal rights should instruct the record owner to comply strictly with the statutory requirements with respect to the exercise of appraisal rights before the vote on the merger agreement at the Cytyc special meeting. A holder of shares held in “street name” who desires appraisal rights with respect to such shares must take such actions as may be necessary to ensure that a timely and proper demand for appraisal is made by the record owner of such shares. Shares held through brokerage firms, banks and other financial institutions are frequently deposited with and held of record in the name of a nominee of a central security depositary, such as Cede & Co., The Depository Trust Company’s nominee. Any holder of shares desiring appraisal rights with respect to such shares who held his or her shares through a brokerage firm, bank or other financial institution is responsible for ensuring that the demand for appraisal is made by the record holder thereof and are urged to consult with such nominee to determine the appropriate procedures that must be followed. The stockholder should instruct such firm, bank or institution that the demand for appraisal must be made by the record holder of the shares, which might be the nominee of a central security depositary if the shares have been so deposited.

As required by Section 262, a demand for appraisal must be in writing and must reasonably inform Cytyc of the identity of the record holder (which might be a nominee as described above) and of such holder’s intention to seek appraisal of such shares.

Stockholders of record who elect to demand appraisal of their shares must mail or deliver their written demand to:

Cytyc Corporation

250 Campus Drive

Marlborough, MA 01752

Attention: Secretary

The written demand for appraisal should specify the stockholder’s name and mailing address, the number of shares owned, and that the stockholder is thereby demanding appraisal of his or her shares and such written demand must be received by Cytyc prior to the Cytyc special meeting. Neither voting (in person or by proxy) against, abstaining from voting on or failing to vote on the proposal to adopt the merger agreement will alone suffice to constitute a written demand for appraisal within the meaning of Section 262.

In addition, the stockholder must not vote his or her shares of common stock in favor of the adoption of the merger agreement. Because a proxy that does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the merger agreement, a stockholder who votes by proxy and who wishes to exercise appraisal rights must vote against the adoption of the merger agreement or abstain from voting on the adoption of the merger agreement. Further, the stockholder must continuously hold the shares of record from the date of making the demand through the effective time of the merger.

Within ten days after the effective time of the merger, the surviving corporation will provide notice of such effective time to each stockholder who, in response to this joint proxy statement/prospectus, has timely delivered and properly made a written demand of appraisal as set forth in this section.

At any time within 60 days after the effective time of the merger, any stockholder who has demanded appraisal will have the right to withdraw his or her demand for appraisal and to accept the merger consideration to which such stockholder is entitled pursuant to the merger. After this period, such holder may withdraw his or her demand for appraisal only with the consent of the surviving corporation in the merger.

##### Table of Contents

Within 120 days after the effective time of the merger, either the surviving corporation in the merger or any stockholder who has timely and properly demanded appraisal of his or her shares and who has complied with the required conditions of Section 262 and is otherwise entitled to appraisal rights may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares of all stockholders who have properly demanded appraisal. Stockholders seeking to exercise appraisal rights should not assume that the surviving corporation will file a petition with respect to the appraisal of the fair value of their shares or that the surviving corporation will initiate any negotiations with respect to the fair value of those shares. The surviving corporation will be under no obligation to take any action in this regard. Accordingly, it is the obligation of stockholders who wish to seek appraisal of their shares of Cytyc common stock to initiate all necessary action with respect to the perfection of their appraisal rights within the time periods and in the manner prescribed in Section 262.

If no petition for appraisal is filed with the Delaware Court of Chancery within 120 days after the effective time of the merger, stockholders’ rights to appraisal will cease and all stockholders will be entitled only to receive the merger consideration as provided for in the merger agreement. No petition timely filed in the Delaware Court of Chancery demanding appraisal will be dismissed as to any stockholders without the approval of the Delaware Court of Chancery, and such approval may be conditioned upon such terms as the Delaware Court of Chancery deems just.

Within 120 days after the effective time of the merger, any stockholder who has complied with subsections (a) and (d) of Section 262 will be entitled, upon written request, to receive from the surviving corporation a statement setting forth the total number of shares of Cytyc common stock not voted in favor of the adoption of the merger agreement with respect to which demands for appraisal have been received by Cytyc and the aggregate number of holders of those shares. This statement must be mailed to the stockholder within ten days after the surviving corporation has received the written request or within ten days after the time for delivery of demands for appraisal under subsection (d) of Section 262 has expired, whichever is later.

If a petition for an appraisal is timely filed by a stockholder and a copy thereof is served upon the surviving corporation, the surviving corporation will then be obligated within 20 days to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached. After notice to such stockholders as required by the Court, the Delaware Court of Chancery is empowered to conduct a hearing on such petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights thereunder. The Delaware Court of Chancery may require the holders of shares of capital stock who demanded payment for their shares to submit their stock certificates to the Delaware Register in Chancery for notation thereon of the pendency of the appraisal proceeding, and if any stockholder fails to comply with such direction, the Delaware Court of Chancery may dismiss the proceedings as to such stockholder.

After determining the stockholders entitled to appraisal of their shares, the Delaware Court of Chancery will determine the fair value of those shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, to be paid, if any, upon the amount determined to be the fair value. In determining the fair value of the shares and, if applicable, a fair rate of interest, the Delaware Court of Chancery will take into account all relevant factors. In Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court” should be considered. Section 262 provides that fair value is to be determined “exclusive of any element of value arising from the accomplishment or expectation of the merger.” Delaware courts have decided that the statutory appraisal remedy, depending on factual circumstances, may or may not be a dissenter’s exclusive remedy. The Delaware Court of Chancery will also determine the amount of interest, if any, to be paid upon the amounts to be received by persons whose shares of common stock of Cytyc have been appraised.

108

##### Table of Contents

Stockholders considering seeking appraisal should bear in mind that the fair value of their shares determined under Section 262 could be more than, the same as or less than the merger consideration they are entitled to receive pursuant to the merger agreement if they do not seek appraisal of their shares. Furthermore stockholders should bear in mind that opinions of investment banking firms as to fairness from a financial point of view are not necessarily opinions as to fair value under Section 262.

The cost of the appraisal proceeding may be determined by the Delaware Court of Chancery and taxed upon the parties as the Delaware Court of Chancery deems equitable in the circumstances. Upon application of a stockholder seeking appraisal rights, the Delaware Court of Chancery may order that all or a portion of the expenses incurred by such stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal. In the absence of such a determination of assessment, each party bears its own expenses.

Any stockholder who has duly demanded an appraisal in compliance with Section 262 will not, after the effective time of the merger, be entitled to vote the shares subject to the demand for appraisal rights for any purpose or be entitled to the payment of dividends or other distributions on those shares (except for any dividends or other distributions payable to stockholders of record as of a record date prior to the effective time of the merger).

In view of the complexity of Section 262 of the DGCL, any Cytyc stockholder who is considering exercising appraisal rights should consult a legal advisor, since failure to comply strictly with the provisions of the DGCL may defeat their appraisal rights.

The foregoing is a summary of Section 262, which sets forth the procedures for demanding statutory appraisal rights. This summary is not intended to be complete and is qualified in its entirety by reference to Section 262, a copy of the text of which is attached hereto as Annex G.

Hologic Stockholders. Hologic stockholders are not entitled to appraisal rights in connection with the merger agreement and the transactions contemplated thereby.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

Cytyc Stockholders

In the opinions of Hogan & Hartson LLP (“Hogan & Hartson”) and Brown Rudnick Berlack Israels LLP (“Brown Rudnick”), the following are the anticipated material United States federal income tax consequences to “U.S. holders” (as defined below) of Cytyc common stock of the receipt of shares of Hologic common stock and cash in exchange for Cytyc common stock pursuant to the merger. This summary is based upon the provisions of the Code, applicable current and proposed United States Treasury Regulations, judicial authorities and administrative rulings and practice, all as in effect as of the date of this registration statement and all of which are subject to change, possibly on a retroactive basis.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of Cytyc common stock that is for United States federal income tax purposes: (i) a citizen or resident of the United States; (ii) a corporation, or other entity taxable as a corporation for United States federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia; (iii) a trust if it (a) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (b) has a valid election in effect under applicable United States Treasury Regulations to be treated as a United States person; or (iv) an estate the income of which is subject to United States federal income tax regardless of its source.

Holders of Cytyc common stock who are not U.S. holders may have different tax consequences than those described below and are urged to consult their own tax advisors regarding the tax treatment to them under United States and non-United States tax laws.

The United States federal income tax consequence to a partner in an entity treated as a partnership, for United States federal income tax purposes, that holds Cytyc common stock generally will depend on the status of the partner and the activities of the partnership. Partners in a partnership holding Cytyc common stock should consult their own tax advisors.

This discussion assumes that a U.S. holder holds Cytyc common stock as a capital asset within the meaning of Section 1221 of the Code. This discussion does not address all aspects of United States federal income taxation that may be relevant to a U.S. holder in light of its personal circumstances or to U.S. holders subject to special treatment under the United States federal income tax laws (for example, insurance companies, dealers or brokers in securities or currencies, traders in securities who elect mark-to-market accounting, tax-exempt organizations, financial institutions, mutual funds, partnerships or other pass-through entities (and persons holding Cytyc common stock through a partnership or other pass-through entity), United States expatriates and stockholders subject to alternative minimum tax, U.S. holders who hold Cytyc common stock as part of a hedging, “straddle,” conversion or other integrated transaction, a person whose functional currency for United States federal income tax purposes in not the U.S. dollar or U.S. holders who acquired their Cytyc common stock through the exercise of employee stock options or other compensation arrangements). In addition, the discussion does not address any aspect of foreign, state, local, estate or gift taxation that may be applicable to a U.S. holder.

Holders of Cytyc common stock are strongly urged to consult with their own tax advisors as to the tax consequences of the merger with respect to their particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws and of changes in those laws.

Tax Consequences of the Merger Generally. In the opinions of Hogan & Hartson and Brown Rudnick, the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. It is a condition to Cytyc’s and Hologic’s respective obligations to complete the merger that Hogan & Hartson and/or Brown Rudnick will have rendered opinions, dated the closing date of the merger, substantially to the effect that the

110

##### Table of Contents

merger will be treated as a reorganization within the meaning of Section 368(a) of the Code. These opinions are and will be based on facts, representations and assumptions set forth in the respective opinions and representations set forth in certificates to be received from Hologic and Cytyc. None of the tax opinions given in connection with the merger or as set forth herein will be binding on the Internal Revenue Service, and neither Hologic nor Cytyc intends to request any ruling from the Internal Revenue Service as to the United States federal income tax consequences of the merger.

Consequently, no assurance can be given that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of those set forth herein. In addition, if any of the facts, representations or assumptions upon which those opinions are based is inconsistent with the actual facts, the United States federal income tax consequences of the merger could be adversely affected.

It is assumed for purposes of the remainder of the discussion that the merger will qualify as a reorganization within the meaning of the Code. Based on this assumption, upon the exchange of Cytyc common stock for a combination of Hologic common stock and cash, a U.S. holder will generally recognize gain (but not loss) in an amount equal to the lesser of:

| • |  | the amount of gain realized (i.e., the excess, if any, of the sum of the cash and the fair market value of the Hologic common stock a U.S. holder received over its tax basis in the Cytyc common stock surrendered in the merger); and

| • |  | the amount of cash received in the merger (other than cash received instead of a fractional share of the Hologic common stock).

For this purpose, gain or loss must be calculated separately for each identifiable block of shares surrendered in the exchange, and a loss realized on one block of shares may not be used to offset a gain realized on another block of shares. If a U.S. holder has different bases or holding periods in respect of shares of Cytyc common stock, a U.S. holder should consult its tax advisor prior to the exchange with regard to identifying the bases or holding periods of the particular shares of Hologic common stock received in the merger.

Any recognized gain will generally be long-term capital gain if the U.S. holder’s holding period with respect to the Cytyc common stock surrendered is more than one year at the effective time of the merger. In some cases, where a U.S. holder actually or constructively owned Hologic common stock immediately before the merger, such cash received in the merger could be treated as having the effect of the distribution of a dividend, under the tests set forth in Section 302 of the Code, in which case such gain would be treated as dividend income. These rules are complex and dependent upon the specific factual circumstances particular to each U.S. holder. Consequently, each U.S. holder that may be subject to those rules should consult its tax advisor as to the application of these rules to the particular facts relevant to such U.S. holder.

Tax Basis and Holding Period. A U.S. holder’s aggregate tax basis in the shares of Hologic common stock received in the merger, including any fractional share interests deemed received by the U.S. holder under the treatment described below, will equal its aggregate adjusted tax basis in the Cytyc common stock surrendered in the merger, increased by the amount of taxable gain, if any, recognized in the merger (including any portion of the gain that is treated as a dividend but excluding any gain or loss resulting from the deemed receipt and redemption of a fractional share interest described below) and decreased by the amount of any cash received in the merger (excluding any cash received instead of a fractional share interest). The holding period for the shares of Hologic common stock received in the merger (including a fractional share interest deemed received and redeemed as described below) will include the holding period for the shares of Cytyc common stock surrendered in the merger.

Cash Instead of a Fractional Share. A U.S. holder who receives cash instead of a fractional share of Hologic common stock will be treated as having received the fractional share of Hologic common stock pursuant

111

##### Table of Contents

to the merger and then as having exchanged the fractional share of Hologic common stock for cash in a redemption by Hologic. In general, this deemed redemption will be treated as a sale or exchange, provided the redemption is not essentially equivalent to a dividend. The determination of whether a redemption is essentially equivalent to a dividend depends upon whether and to what extent the redemption reduces the U.S. holder’s deemed percentage stock ownership of Hologic. While this determination is based on each U.S. holder’s particular facts and circumstances, the Internal Revenue Service has ruled that a redemption is not essentially equivalent to a dividend and will therefore result in sale or exchange treatment in the case of a stockholder of a publicly held company whose relative stock interest is minimal and who exercises no control over corporate affairs if the redemption results in even a minor reduction in the stock interest of the stockholder. As a result, the redemption of a fractional share of Hologic common stock is generally treated as a sale or exchange and not as a dividend, and a U.S. holder generally will recognize capital gain or loss equal to the difference between the amount of cash received and the basis in its fractional share of Hologic common stock as set forth above. This capital gain or loss generally will be long-term capital gain or loss if, as of the effective time of the merger, the holding period for the shares is greater than one year. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding. Cash payments received in the merger by a U.S. holder may, under certain circumstances, be subject to information reporting and backup withholding (currently at a rate of 28%) of the cash payable to the holder, unless the holder provides proof of an applicable exemption or furnishes its taxpayer identification number, and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and will be allowed as a refund or credit against the U.S. holder’s United States federal income tax liability, provided that the required information is timely furnished to the Internal Revenue Service.

Reporting Requirements. A U.S. holder who receives shares of Hologic common stock as a result of the merger will be required to retain records pertaining to the merger and will be required to file with its United States federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger.

Hologic Stockholders

If you are a Hologic stockholder, the merger will not be taxable to you.

REGULATORY AND OTHER APPROVALS REQUIRED FOR THE MERGER

Under the merger agreement, subject to the terms of the merger agreement, each of Hologic and Cytyc has agreed to use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable law to complete the merger and the other transactions contemplated by the merger agreement, including (i) preparing and filing as promptly as practicable with any governmental authority or other third party all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents; and (ii) obtaining and maintaining all approvals, consents, waivers, licenses, orders, registrations, permits, authorizations, clearances and other confirmations required to be obtained from any governmental authority or other third party that are necessary, proper or advisable to complete the merger and the other transactions contemplated by the merger agreement.

A condition to Hologic’s and Cytyc’s respective obligations to complete the merger is that any waiting period applicable to the merger under the HSR Act will have expired or been terminated. A further condition is that all required governmental regulatory consents and approvals will have been obtained except those that in the aggregate fall below the materiality standard described in the merger agreement. See “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 128.

Under the HSR Act and the rules and regulations promulgated thereunder, certain transactions, including the merger, may not be completed unless certain waiting period requirements have expired or been terminated. Under the HSR Act, the merger may not be completed until approximately 30 days after the initial filing (unless early termination of this waiting period is granted) or, if the Antitrust Division of the U.S. Department of Justice or the U.S. Federal Trade Commission issues a request for additional information, 30 days after Hologic and Cytyc have “substantially complied” with such request for additional information (unless this period is shortened pursuant to a grant of earlier termination). Notwithstanding such expiration or termination, at any time before or after the effective time of the merger the U.S. Federal Trade Commission, the U.S. Department of Justice or others could take action under the antitrust laws with respect to the merger, including seeking to enjoin the completion of the merger, to rescind the merger or to conditionally approve the merger upon the divestiture of assets of Hologic or Cytyc or to impose restrictions on the operations of the combined company post-closing. Each of Hologic and Cytyc filed a Pre-Merger Notification and Report Form pursuant to the HSR Act with the Justice Department and the Federal Trade Commission on June 1, 2007. There can be no assurance that the merger will not be challenged on antitrust grounds or, if such a challenge is made, that the challenge will not be successful. In addition, state antitrust authorities and private parties in certain circumstances may bring legal action under the antitrust laws seeking to enjoin the merger or seeking conditions to the completion of the merger. Under the merger agreement, subject to the conditions and limitations described in the merger agreement, Hologic and Cytyc have agreed to take all actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act.

Other than the filings described above, neither Hologic nor Cytyc is aware of any regulatory approvals required to be obtained, or waiting periods required to expire, to complete the merger. If Hologic and Cytyc discover that other approvals or waiting periods are necessary, Hologic and Cytyc will seek to obtain or comply with them in accordance with the merger agreement.

THE MERGER AGREEMENT

The following is a summary of the material terms of the merger agreement. This summary does not purport to describe all the terms of the merger agreement and is qualified by reference to the complete merger agreement, a copy of which is attached as Annex A to this joint proxy statement/prospectus and incorporated by reference. The rights and obligations of the parties are governed by the express terms and conditions of the merger agreement and not by this summary or any other information contained in this joint proxy statement/prospectus. All stockholders of Hologic and Cytyc are urged to read the merger agreement carefully and in its entirety.

Explanatory Note Regarding Summary of Merger Agreement and Representations and Warranties in the Merger Agreement

The summary of the terms of the merger agreement is intended to provide information about the terms of the merger. The terms and information in the merger agreement should not be relied on as disclosures about Hologic or Cytyc without consideration of the entirety of public disclosure by Hologic and Cytyc as set forth in their respective public reports with the SEC. The terms of the merger agreement (such as the representations and warranties) govern the contractual rights and relationships and allocate risks between the parties in relation to the merger. In particular, the representations and warranties made by the parties to each other in the merger agreement have been negotiated between the parties with the principal purpose of setting forth their respective rights with respect to their obligation to close the merger should events or circumstances change or be different from those stated in the representations and warranties. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders under federal securities laws. Matters may change from the state of affairs contemplated by the representations and warranties. Hologic and Cytyc will provide additional disclosure in their public reports to the extent that they are aware of the existence of any material facts that are required to be disclosed under federal securities laws and will update such disclosure as required by federal securities laws.

Structure of the Merger

The merger agreement provides for the merger of Cytyc with and into Nor’easter Corp., a wholly owned subsidiary of Hologic that was formed for the purpose of the merger, with Nor’easter Corp. surviving the merger. At the effective time of the merger, the separate existence of Cytyc will cease and the surviving entity will remain a wholly owned subsidiary of Hologic, and Nor’easter Corp. will be renamed “Cytyc Corporation.” The merger will become effective when Nor’easter Corp. and Cytyc file a certificate of merger with the Secretary of State of the State of Delaware (or at such later time as Hologic and Cytyc mutually agree and specify in the certificate of merger). The time the merger becomes effective is referred to as the effective time of the merger.

Merger Consideration

At the effective time of the merger, each issued and outstanding share of Cytyc common stock will be converted into the right to receive 0.52 of a share of Hologic common stock and $16.50 in cash without interest. Cytyc stockholders will receive cash in lieu of any fractional shares of Hologic common stock that would have otherwise been received in the merger. See “—Fractional Shares” beginning on page 117. If between the date of the merger agreement and the effective time of the merger there is a reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend with respect to the capital stock of Hologic or Cytyc, the merger consideration will be appropriately adjusted.

Hologic and Cytyc expect that, upon completion of the merger, assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024, the Cytyc stockholders immediately prior to the merger will own approximately 55% of the outstanding common stock of the combined company and the Hologic stockholders immediately prior to the merger will own approximately 45% of the outstanding common stock of the combined company.

116

##### Table of Contents

Exchange of Shares

Prior to the effective time of the merger, Hologic will appoint American Stock Transfer & Trust Company or another bank or trust company reasonably satisfactory to Cytyc to act as an exchange agent to handle the exchange of Cytyc common stock in the merger for the merger consideration. Promptly after the effective time of the merger, and in any event within ten business days after the effective time of the merger, Hologic will send, or will cause the exchange agent to send, to each holder of Cytyc common stock at the effective time of the merger a letter of transmittal for use in the exchange and instructions explaining how to surrender stock certificates or transfer uncertificated shares of Cytyc common stock to the exchange agent. Holders of Cytyc common stock that surrender their stock certificates or transfer their uncertificated shares to the exchange agent, together with a properly completed letter of transmittal, will be entitled to receive the appropriate merger consideration. You should not return stock certificates with the enclosed proxy card.

After the effective time of the merger, holders of unexchanged shares of Cytyc common stock will not be entitled to receive any dividends or other distributions payable by Hologic after the closing until their shares of Cytyc common stock are surrendered. However, once those shares are surrendered, Hologic will pay or will cause the exchange agent to pay the holder, without interest, any dividends with a record date after the effective time of the merger that were previously paid to Hologic stockholders or are payable at the time the shares of Cytyc common stock are surrendered.

Fractional Shares

Hologic will not issue fractional shares of Hologic common stock in the merger. All fractional shares of Hologic common stock that a holder of shares of Cytyc common stock would otherwise be entitled to receive as a result of the merger will be aggregated. For any fractional share that results from such aggregation, the exchange agent will pay the holder an amount of cash, without interest, equal to the fraction of a share of Hologic common stock to which the Cytyc stockholder would otherwise be entitled in the merger multiplied by the closing sale price of a share of Hologic common stock on the closing date.

Cytyc Stock Options, Restricted Stock Units, Performance Shares, Deferred Shares, Employee Stock Purchase Plan

Under the merger agreement, the board of directors of Cytyc, as soon as practicable following the date of the merger agreement, must adopt resolutions or take any other actions as may be required to effect the following:

| • |  | each stock option to purchase shares of common stock of Cytyc outstanding immediately prior to the effective time of the merger will be amended and converted into an option to acquire, on the same terms and conditions (after giving effect to any applicable acceleration of vesting thereunder) as were applicable under the Cytyc stock option, the number of shares of Hologic common stock (rounded down to the nearest whole share) equal to the sum of:

| • |  | the product of (A) the number of shares of Cytyc common stock subject to the Cytyc stock option and (B) the exchange ratio; and

| • |  | the product of (A) the number of shares of Cytyc common stock subject to the Cytyc stock option and (B) the quotient obtained by dividing (x) $16.50 by (y) the average of the per share closing sale prices of Hologic common stock for the ten consecutive trading days ending on (and including) the date that is three trading days prior to the closing date,

at an exercise price per share of Hologic common stock (rounded up to the nearest whole cent) equal to the quotient obtained by dividing (i) the aggregate exercise price for the shares of Cytyc common stock subject to the Cytyc stock option by (ii) the aggregate number of shares of Hologic common stock to be subject to the Cytyc stock option after giving effect to the adjustments in this bullet point and the two sub-bullet points immediately above;

| • |  | each restricted stock unit of Cytyc outstanding immediately prior to the effective time of the merger will be amended and converted into the right to receive, on the same terms and conditions (after giving effect to any applicable acceleration of vesting thereunder) as were applicable under the Cytyc restricted stock unit, the number of shares of Hologic common stock (rounded down to the nearest whole share) equal to the sum of:

| • |  | the product of (A) the number of shares of Cytyc common stock subject to the Cytyc restricted stock unit and (B) the exchange ratio; and

| • |  | the product of (A) the number of shares of Cytyc common stock subject to the Cytyc restricted stock unit and (B) the quotient obtained by dividing (x) $16.50 by (y) the average of the per share closing sale prices of Hologic common stock for the ten consecutive trading days ending on (and including) the date that is three trading days prior to the closing date;

| • |  | each performance share of Cytyc outstanding immediately prior to the effective time of the merger will vest at the target award level in accordance with the terms and conditions applicable under the Cytyc performance share and holders thereof will be entitled to receive the merger consideration on the same basis as all other shares of common stock of Cytyc;

| • |  | each share of common stock of Cytyc deferred, a “share unit”, under the Cytyc amended and restated director compensation method plan will be converted into, on the same terms and conditions (after giving effect to any applicable acceleration of vesting thereunder) as are applicable under the Cytyc amended and restated director compensation method plan, a number of shares of Hologic common stock (rounded down to the nearest whole share) equal to the sum of:

| • |  | the product of (A) the number of shares of Cytyc common stock subject to the Cytyc share unit and (B) the exchange ratio; and

| • |  | the product of (A) the number of shares of Cytyc common stock subject to the Cytyc share unit and (B) the quotient obtained by dividing (x) $16.50 by (y) the average of the per share closing sale prices of Hologic common stock for the ten consecutive trading days ending on (and including) the date that is three trading days prior to the closing date;

| • |  | holders of each share of Cytyc common stock accrued in 2007 for issuance to members of the board of directors of Cytyc on January 1, 2008 will be entitled to receive the merger consideration on the same basis as all other shares of Cytyc common stock.

The merger agreement further provides that the board of directors of Cytyc, as soon as practicable following the date of the merger agreement, must adopt any resolutions or take any other actions as may be required to provide that with respect to the Cytyc employee stock purchase plan:

| • |  | each participant’s outstanding right to purchase shares of Cytyc common stock under the Cytyc employee stock purchase plan will terminate on the day immediately prior to the day on which the effective time of the merger occurs, provided that all amounts allocated to each participant’s account under the Cytyc employee stock purchase plan as of that date will then be used to purchase from Cytyc whole shares of Cytyc common stock at the applicable price determined under the terms of the Cytyc employee stock purchase plan for the then outstanding offering periods using that date as the final purchase date for each particular offering period; and

| • |  | the Cytyc employee stock purchase plan will terminate immediately following those purchases of Cytyc common stock.

Hologic has agreed that, as soon as practicable following the effective time of the merger, it will deliver to the holders of Hologic stock options, restricted stock units, and share units that were converted from Cytyc stock options, restricted stock units and share units appropriate notices setting forth those holders’ rights pursuant to the respective stock incentive plans and the contracts evidencing the grants of those converted options, restricted stock units and share units, as the case may be, which will provide, among other things, that those converted

118

##### Table of Contents

options, restricted stock units, share units and contracts have been assumed by Hologic and will continue in effect on the same terms and conditions (subject to the adjustments described above after giving effect to the merger).

The merger agreement provides that, except as otherwise described above and except to the extent required under the respective terms of the converted options, restricted stock units and share units, as the case may be, all restrictions or limitations on transfer and vesting with respect to such converted options, restricted stock units and share units, to the extent that those restrictions or limitations shall not have already lapsed, and all other terms of thereof, will remain in full force and effect with respect to those converted options, restricted stock units and share units after giving effect to the merger and their assumption by Hologic as set forth above.

Hologic has agreed to take all action necessary for the assumption of the Cytyc stock options, restricted stock units and share units as described above, including the reservation, issuance and listing of a sufficient number of shares of Hologic common stock as is necessary to effectuate the transactions described above. Subject to receiving full cooperation from Cytyc and its independent registered public accounting firm, within one business day of the closing date, Hologic is required to file a registration statement on an appropriate form, or a post-effective amendment to a previously filed registration statement, with respect to the shares of Hologic common stock subject to the above converted options, restricted stock units and share units and, where applicable, is required to use all commercially reasonable efforts to have the registration statement declared effective as soon as practicable after the effective time of the merger.

Certain Covenants

Hologic and Cytyc have agreed to certain covenants in the merger agreement, including:

Stockholder Meetings. Each of Hologic and Cytyc has agreed to use all commercially reasonable efforts in accordance with and subject to the DGCL, its certificate of incorporation and bylaws and Nasdaq rules to cause a meeting of its stockholders to be called and held as soon as reasonably practicable for the purpose of voting on the adoption of the merger agreement and the transactions contemplated thereby, including the merger, in the case of Cytyc, and for the purpose of securing stockholder approval of the stock issuance in connection with the merger and the charter amendment to increase the authorized shares of capital stock, in the case of Hologic. In addition, each party has agreed to use all commercially reasonable efforts to obtain from its stockholders the required stockholder vote, in the case of Hologic, in favor of the and the charter amendment proposal and the stock issuance proposal, and in the case of Cytyc, in favor of adoption of the merger agreement and the transactions contemplated thereby, including the merger.

No Solicitation. The merger agreement provides that, from the time of the execution of the merger agreement until the completion of the merger or the termination of the merger agreement, subject to certain exceptions, neither Hologic nor Cytyc will, nor will either party authorize or permit any of their respective subsidiaries, or any of their respective directors, officers or employees, investment bankers, attorneys, accountants, consultants or other agents or advisors to, directly or indirectly:

| • |  | solicit, initiate or take any action to knowingly facilitate or knowingly encourage the submission of any “acquisition proposal” of the type described below;

| • |  | enter into, continue or otherwise participate in any discussions or negotiations with, furnish any information relating to itself or any of its subsidiaries to or afford access to the business, properties, assets, books or records of itself or any of its subsidiaries to, otherwise cooperate in any way with, or knowingly assist, participate in, knowingly facilitate or knowingly encourage any effort by any third party seeking to make or who has made an acquisition proposal;

| • |  | make an “adverse recommendation change,” which means either of the following as the context may indicate: any recommendation by its board of directors of an acquisition proposal or any failure by its board of directors to make, or any withdrawal or modification in a manner adverse to the other party of, its recommendation to its stockholders that, in the case of Hologic stockholders, they approve the amendment of the Hologic charter and the issuance of Hologic common stock to Cytyc stockholders in the merger, or in the case of Cytyc stockholders, they adopt the merger agreement;

| • |  | grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of itself or any of its subsidiaries;

| • |  | enter into any agreement in principle, letter of intent, term sheet or other similar instrument relating to an acquisition proposal (other than a confidentiality agreement of the sort and in the circumstances described in the following paragraph); or

121

##### Table of Contents

| • |  | propose publicly or agree to do any of the foregoing related to any acquisition proposal.

Notwithstanding the foregoing, the board of directors of each of Hologic and Cytyc may, prior to the receipt of the relevant stockholder approval, (i) engage in discussions or negotiations with any third party in response to an unsolicited bona fide written acquisition proposal that the party’s board of directors has determined in good faith (after consultation with its outside legal counsel and financial advisors of nationally recognized reputation) constitutes or is reasonably likely to lead to a superior proposal (as described and defined below); and (ii) after making such determination furnish to such third party non-public information relating to that party or any of its subsidiaries pursuant to a confidentiality agreement with terms no less favorable than those contained in the existing confidentiality agreement between Hologic and Cytyc, if, in each case, the board of directors of such party determines in good faith by a majority vote, after considering the advice of outside legal counsel, that failing to take such action would be inconsistent with its fiduciary duties under applicable law.

The merger agreement prohibits a party from engaging in such discussions or negotiations or providing such information unless that party has delivered to the other party prior written notice advising the other party that it intends to take such action. The merger agreement also requires that the parties notify each other if any acquisition proposals are presented to either party, and the parties are required to keep each other reasonably informed, on a current basis, of the status and details of any acquisition proposals.

Subject to compliance with the terms of the merger agreement, each party is permitted to take and disclose to its stockholders a position with respect to any acquisition proposal as may be contemplated by Rule 14e-2(a) under the Exchange Act or make a statement required under Rule 14d-9 under the Exchange Act or make any disclosure of factual matters to its stockholders if, in the good faith judgment of its board of directors (after consultation with its outside legal counsel), it is required to disclose in order not to breach its fiduciary duties to its stockholders under applicable law.

An “acquisition proposal” for Cytyc is any inquiry, proposal or offer relating to, or any third party indication of interest in, (i) any direct or indirect acquisition or purchase of 20% or more of the consolidated net assets of Cytyc and its subsidiaries or 20% or more of any class of equity or voting securities of Cytyc or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of Cytyc; (ii) any tender offer (including a self-tender offer) or exchange offer that, if completed, would result in such third party beneficially owning 20% or more of any class of equity or voting securities of Cytyc or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of Cytyc; or (iii) a merger, consolidation, share exchange, business combination, sale of substantially all of the assets, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Cytyc or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of that person, in each case, subject to certain exceptions set forth in the merger agreement.

An “acquisition proposal” for Hologic is any inquiry, proposal or offer relating to, or any third party indication of interest in, (i) any direct or indirect acquisition or purchase of 20% or more of the consolidated net assets of Hologic and its subsidiaries or 20% or more of any class of equity or voting securities of Hologic or any of its subsidiaries that, if completed, would result in the third party beneficially owning 20% or more of any class of equity or voting securities of Hologic or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of Hologic; or (ii) any tender offer (including a self-tender offer) or exchange offer that, if completed, would result in such third party beneficially owning 20% or more of any class of equity or voting securities of Hologic or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the consolidated assets of Hologic, in each case, subject to certain exceptions set forth in the merger agreement. Notwithstanding the foregoing, Hologic is permitted to engage in acquisition discussions, which includes any inquiries, proposals or offerings relating to a proposed acquisition or purchase by Hologic of 50% or more of any class of equity or voting securities of a third party or any purchase or acquisition of the business or assets of a third party.

122

##### Table of Contents

A “superior proposal” is a bona fide, unsolicited written acquisition proposal (which definition is read, for this purpose, without the word “inquiry”) for at least a majority of the outstanding shares of common stock of Cytyc or Hologic (as the case may be) or a sale or purchase of all or substantially all of the assets of Cytyc or Hologic (as the case may be) on terms that the board of directors of such party determines in good faith by a majority vote, after consultation with its legal advisor and financial advisors of nationally recognized reputation and taking into account such matters deemed relevant in good faith by such board of directors, including among other things, all the terms and conditions of the acquisition proposal, including any break-up fees, expense reimbursement provisions, conditions to completion and long-term strategic considerations, are more favorable from a financial point of view to the stockholders of such party than the merger and for which (i) financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to be available; and (ii) such proposed transaction is reasonably capable of being completed on the terms set forth in the acquisition proposal, in each case as determined by the board of directors of that party.

Each party has agreed to terminate, and to cause its subsidiaries, advisors, employees and other agents to terminate, any discussions or negotiations with any person with respect to any acquisition proposal that began before the date of the merger agreement.

Board of Directors’ Covenant to Recommend. The board of directors of Hologic has agreed to recommend the approval by Hologic stockholders of (i) a proposal to be effective immediately prior to the effective time of the merger, to amend the Hologic charter, to increase the authorized number of shares of Hologic common stock and (ii) a proposal to issue shares of Hologic common stock to Cytyc stockholders in the merger on the terms and conditions set forth in the merger agreement. The board of directors of Cytyc has agreed to recommend the approval by Cytyc stockholders of a proposal to adopt the merger agreement and the transactions contemplated thereby, including the merger.

Notwithstanding the foregoing, subject to the terms of the merger agreement, including applicable notice requirements, each party’s board of directors can make an adverse recommendation change, other than in response to an acquisition proposal, if (i) it has not received the approval of its stockholders in connection with the merger; and (ii) in response to a material development or change in circumstances occurring or arising after May 20, 2007 that was not known to such party’s board of directors as of or prior to May 20, 2007 (which change or development does not relate to an acquisition proposal and which is not, and does not result from, a change in the market price of the common stock of the other party primarily as a result of the announcement of the transactions contemplated by the merger agreement) (referred to as an “intervening event”), the board of directors of such party determines in good faith (after consultation with, and taking into account the advice of, legal counsel) that, in light of such intervening event, the failure of the board of directors to effect such an adverse recommendation change would result in a breach of its fiduciary duties under applicable law.

In addition, subject to the terms of the merger agreement, including applicable notice requirements, each party and its board of directors can make an adverse recommendation change, in response to an acquisition proposal, and, subject to payment of applicable termination fees, immediately terminate the merger agreement, if (i) it has not received the approval of its stockholders in connection with the merger; (ii) it has received an unsolicited bona fide written acquisition proposal from a third party; (iii) its board of directors has determined in good faith (after consultation with its outside legal counsel and financial advisors of a national recognized reputation and taking into account any adjustments to the terms and conditions of the merger agreement proposed by the other party) that the acquisition proposal constitutes a superior proposal; and (iv) its board of directors, after consultation with outside legal counsel, determines in good faith that failing to take such action would be inconsistent with its fiduciary duties under applicable law.

Unless the merger agreement is otherwise terminated in accordance with its terms, whether or not (i) the Hologic board of directors has made an adverse recommendation change; or (ii) an acquisition proposal has been publicly proposed or announced or otherwise submitted to Hologic or any of its advisors, the Hologic proposals

123

##### Table of Contents

described above must be submitted to Hologic stockholders at a meeting of its stockholders called for these purposes. Unless the merger agreement is otherwise terminated in accordance with its terms, whether or not (i) Cytyc’s board of directors has made an adverse recommendation change; or (ii) an acquisition proposal has been publicly proposed or announced or otherwise submitted to Cytyc or any of its advisors, the Cytyc proposals described above must be submitted to Cytyc stockholders at a meeting of its stockholders called for this purpose.

Interim Operations of Hologic and Cytyc. Each of Hologic and Cytyc has undertaken a separate covenant that places restrictions on it and its subsidiaries until the earlier of the effective time and the date the merger agreement is terminated. In general, Hologic and its subsidiaries and Cytyc and its subsidiaries are required to conduct their respective businesses in the ordinary course consistent with past practice and to use all commercially reasonable efforts to preserve intact their respective business organizations and relationships with third parties. The companies have also agreed to some specific restrictions which (subject to exceptions described in the merger agreement) are substantially, but not entirely, comparable, because, in a number of instances, an action is applicable to only one of the companies by nature.

| • |  | amend its organizational documents;

| • |  | split, combine or reclassify its shares of capital stock or those of its subsidiaries;

| • |  | declare dividends or redeem, repurchase or otherwise acquire or offer to redeem, repurchase or otherwise acquire any of its capital stock or those of its subsidiaries, except for dividends by any of its subsidiaries on a pro rata basis to the equity owners thereof and any transaction between the company and any of its subsidiaries or between its subsidiaries;

| • |  | issue, deliver, sell or authorize the issuance, delivery or sale of any equity securities, options or other securities convertible into or exchangeable or exercisable for equity securities, except under limited circumstances;

| • |  | acquire or dispose of assets, except for acquisitions or dispositions (i) in the ordinary course of business consistent with past practice, (ii) below certain dollar thresholds, (iii) between the company and any of its subsidiaries or between its subsidiaries or (iv) that are identified as permitted acquisitions or dispositions;

| • |  | other than in connection with permitted acquisitions, make any loans, advances or capital contributions to, or investments in, any other person, other than in the ordinary course of business consistent with past practice or between the company and any of its subsidiaries or between its subsidiaries;

| • |  | create, incur or assume any indebtedness for borrowed money or guarantees thereof, other than in the ordinary course consistent with past practice, under existing lines of credit for specified purposes, or between the company and any of its subsidiaries or between its subsidiaries;

| • |  | enter into any agreement that limits or otherwise restricts in any material respect such party, or that would reasonably be expected to limit or restrict the combined company after the effective time of the merger, from engaging or competing in any material line of business;

| • |  | grant or increase any severance or termination pay or supplemental retirement or post employment benefit to (or amend any existing arrangement with) any director or specified officers of the company or any of its subsidiaries;

| • |  | increase benefits payable under any existing severance or termination pay policies or employment agreements;

| • |  | enter into any employment, deferred compensation or other similar agreement (or amend any such existing agreement) with any director or specified officers of the company or any of its subsidiaries;

| • |  | establish, adopt or amend (except as required by applicable law) any collective bargaining, bonus, profit-sharing, thrift, pension, retirement, deferred compensation, compensation, stock option, restricted stock, or other benefit plan or arrangement covering any director or specified officers of the company or any of its subsidiaries;

| • |  | adopt or change accounting methods, principles or practices, except as may be required by U.S. GAAP;

| • |  | adopt or change any material tax election or settle or compromise any material income tax liability;

| • |  | adopt or change any material method of tax accounting, other than any method adopted or changed pursuant to a request made by a taxing authority or as required by applicable law;

| • |  | fail to use commercially reasonable efforts to maintain in full force and effect insurance coverage substantially similar to insurance coverage maintained on the date of the merger agreement;

| • |  | settle, or offer to propose to settle, any legal proceedings that arise out of the transactions contemplated by the merger agreement; or

| • |  | agree or commit to do any of the foregoing.

Reasonable Best Efforts Covenant. Hologic and Cytyc have each agreed to use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable law to complete the merger and the other transactions contemplated by the merger agreement, including taking all necessary actions to satisfy the closing conditions as promptly as practicable, preparing and filing requisite documents with governmental entities or other third parties and obtaining and maintaining all necessary approvals, consents and authorizations. However, neither Hologic nor Cytyc is required to enter into a settlement or other agreement with any governmental entity in connection with the transactions contemplated by the merger agreement or divest or take any other action with respect to any of its subsidiaries or any of their respective affiliates’ businesses, assets or properties if the result would reasonably be expected to:

| • |  | materially and adversely diminish the benefits expected to be derived by the parties on the date of the merger agreement from the combination of Hologic and Cytyc via the merger (such combined business to be taken as a whole), in such a manner that either Hologic or Cytyc would not have entered into the merger agreement in the face of such materially and adversely diminished benefits, or

| • |  | otherwise have a material adverse effect (but ignoring the exception for effects caused by the announcement of the merger in the definition of material adverse effect) after the effective time of the merger on Hologic and its subsidiaries, taken as a whole, which is referred to as a regulatory material adverse effect.

Corporate Governance and Other Matters.

Board of Directors. As of the effective time of the merger, the board of directors of Hologic will consist of eleven directors, six of whom will be designated by Hologic and five of whom will be designated by Cytyc. Four of the six persons designated by Hologic will be “independent” directors as defined under applicable listing standards, and the remaining two persons will be John W. Cumming, current chairman and chief executive officer of Hologic, and Glenn P. Muir, current chief financial officer of Hologic. Three of the five persons designated by Cytyc will be “independent” directors under applicable Nasdaq listing standards, and the remaining two persons will be Patrick J. Sullivan, current chairman, chief executive officer and president of Cytyc, and Daniel Levangie, current executive vice president of Cytyc and president of Cytyc surgical products.

From the effective time of the merger until immediately prior to Hologic’s annual meeting of stockholders to be held in 2009, vacancies on the board of directors of Hologic will be filled as follows: (i) all vacancies created by the cessation of service of a continuing Hologic director (“Continuing Hurricane Director” as defined in the merger agreement) who is an independent director will be filled by a nominee proposed to the nominating and corporate governance committee by a majority of the remaining continuing Hologic directors; (ii) all vacancies created by the cessation of service of a continuing Cytyc director (“Continuing Cyclone Director” as defined in the merger agreement) who is an independent director will be filled by a nominee proposed to the nominating and corporate governance committee by a majority of the remaining continuing Cytyc directors; and (iii) all remaining vacancies will be filled by a nominee proposed and selected by the nominating and corporate governance committee. This agreement between the parties will be reflected in the amendments to Hologic’s bylaws. The amendment of this provision of Hologic’s bylaws will require the affirmative vote of at least 75% of the full board of directors of Hologic. See “Hologic Bylaws Amendment” beginning on page 155.

Committees of a Board of Directors. At the effective time of the merger, the board of directors of Hologic will have an audit, a compensation, a nominating and corporate governance and a corporate development committee. Directors serving on each of these committees, are required to meet the independence standards under applicable Nasdaq listing standards, and, in addition, each member of the audit committee is required to meet the additional listing standards applicable to audit committee members.

The audit, nominating and corporate governance and corporate development committees will each consist of an odd number of directors, consisting of one more continuing Hologic director than continuing Cytyc directors. The chairman of each of these committees will be a continuing Hologic director. The compensation committee will consist of an even number of directors, consisting of an equal number of continuing Cytyc directors and continuing Hologic directors. The chairman of the compensation committee will be a continuing Cytyc director.

Chairman; Chairman Emeritus and CEO of Hologic. At the effective time of the merger, Mr. John W. Cumming, currently Hologic’s chairman and chief executive officer, will serve as the chief executive officer of Hologic, and Mr. Patrick J. Sullivan, currently Cytyc’s chairman, chief executive officer and president, will serve as chairman of Hologic’s board of directors. In addition, at the effective time of the merger, Dr. Jay A. Stein, currently chairman emeritus, director and chief technical officer of Hologic, will serve as chairman emeritus and chief technical officer of Hologic.

Headquarters. At the effective time of the merger, the location of the corporate headquarters and principal executive offices of Hologic will be 35 Crosby Drive, Bedford, Massachusetts.

Certain Employee Benefits Matters. The merger agreement provides that Hologic will honor all accrued and vested benefit obligations to and contractual rights of current and former employees of Cytyc and Hologic and their respective subsidiaries, referred to as covered employees, under their respective existing employee plans, to the extent accrued and vested as of the effective time of the merger. Hologic and Cytyc, acting in good faith, will cooperate in reviewing their existing employee plans with a view towards developing appropriate

126

##### Table of Contents

employee benefit and compensation plans, which are referred to as the new benefit plans, after the effective time of the merger, and which among other things: (i) will treat similarly situated covered employees on a substantially equivalent basis, taking into account all relevant factors, including duties, responsibilities, geographic location, tenure and qualifications; and (ii) will not discriminate between covered employees who at the effective time of the merger are covered by Cytyc employee plans, on the one hand, and those covered by Hologic employee plans, on the other hand. Hologic has agreed to adopt the new benefit plans, subject to customary rights to subsequently amend or terminate the plans as Hologic deems appropriate.

The new benefit plans will provide for the following:

| • |  | eligible participants will receive service credit for purposes of eligibility, participation, vesting and levels of benefits for all periods of employment with Cytyc or Hologic or any of their respective subsidiaries before the effective time of the merger;

| • |  | all pre-existing conditions or limitations under any new benefit plan which is a welfare plan will be waived to the extent waived under the corresponding plan in which the employee participated immediately before the effective time of the merger; and

| • |  | credit will be given for the plan year in which the effective time of the merger occurs towards applicable deductibles and annual out-of-pocket limits for expenses incurred before the effective time of the merger.

Please see “The Merger—Interests of Hologic Executive Officers and Directors in the Merger,” beginning on page 74 and “The Merger—Interests of Cytyc Executive Officers and Directors in the Merger” beginning on page 94 for additional information on employee benefits matters covered in the merger agreement.

Indemnification and Insurance. Hologic has agreed to cause the surviving corporation and the surviving corporation has agreed to do the following:

| • |  | assume the obligations with respect to rights to indemnification and exculpation from liabilities (including advancement of expenses), for acts or omissions occurring at or before the effective time of the merger in favor of the current or former directors or officers of Cytyc or its subsidiaries as provided under Cytyc’s certificate of incorporation, bylaws or any indemnification contract between such directors or officers as in effect on May 20, 2007, without further action, as of the effective time of the merger, and those obligations will survive the merger and will continue in full force and effect in accordance with their terms; and

| • |  | for six years after the effective time of the merger, Hologic will, or will cause the surviving corporation to, provide officers’ and directors’ liability insurance in respect of acts or omissions occurring before the effective time of the merger covering each current or former director or officer of Cytyc or its subsidiaries that is currently covered by Cytyc’s directors’ and officers’ liability insurance policies. This insurance tail coverage must be no less favorable than the Cytyc policy in effect on May 20, 2007, except that Hologic or the surviving corporation, as the case may be, will only be obligated to pay up to 200% of the annual premium paid by Cytyc for such insurance as of May 20, 2007. In lieu of the foregoing, Cytyc may obtain prepaid policies prior to the effective time of the merger that provide the officers and directors of Cytyc with coverage of equivalent amount and on no more favorable terms than the Cytyc policy in effect on May 20, 2007.

Listing of Hologic Stock. Hologic has agreed to use all commercially reasonable efforts to cause the shares of Hologic common stock to be issued in the merger to be listed on the Nasdaq, subject to official notice of issuance. Hologic will continue to use the trading symbol “HOLX” for the shares of Hologic common stock issuable to the Cytyc stockholders in the merger.

Cooperation with Respect to Financing. Cytyc has agreed to provide on a timely basis, and use all commercially reasonable efforts to cause its officers, employees and advisors to provide on a timely basis, all reasonable cooperation in connection with the arrangement of financing contemplated by the financing commitment letter between the arrangers and Hologic or any alternative financing Hologic may seek in order to complete the merger. For more information regarding the Commitment Letter, please see “The Merger—Financing of the Merger” on page 58.

Certain Other Covenants. The merger agreement contains additional mutual covenants, which include, among other things, agreements by each party to:

| 1. | to approve an amendment of the Hologic charter, effective immediately prior to the effective time of the merger, to increase the authorized number of shares of Hologic common stock from 90,000,000 shares to 300,000,000 shares, as described in “Hologic Charter Amendment” beginning on page 143;

##### Table of Contents

Hologic Record Date; Shares Entitled to Vote

The Hologic board of directors has fixed the close of business on [ ], 2007 as the record date for Hologic stockholders entitled to notice of and to vote at the Hologic special meeting of Hologic stockholders or any adjournment or postponement of the Hologic special meeting.

The only outstanding voting securities of Hologic are the shares of Hologic common stock. Only holders of record of the shares of Hologic common stock on the Hologic record date are entitled to notice of and to vote at the Hologic special meeting. Under the Hologic charter, each share of Hologic common stock is entitled to one vote on all matters submitted to Hologic stockholders.

On the Hologic record date, there were approximately [ ] outstanding shares of Hologic common stock entitled to vote at the Hologic special meeting. Votes are exercisable in person, through the Internet, by telephone or by a properly executed and delivered proxy card with respect to the Hologic special meeting as described in “—Voting of Proxies” beginning on page 137.

Quorum Requirement

Under Delaware law and the Hologic bylaws, a quorum of Hologic stockholders at the special meeting is necessary to transact business at the Hologic special meeting. The presence of holders representing at least a majority of the votes of all outstanding Hologic common stock entitled to vote at the Hologic special meeting, whether present in person or by properly executed and delivered proxy, will constitute a quorum for the transaction of business at the Hologic special meeting.

All shares of Hologic common stock represented in person or by proxy at the Hologic special meeting, including abstentions and broker non-votes (as defined below) will be treated as present for purposes of determining the presence or absence of a quorum at the Hologic special meeting.

Under NASD rules, brokers who hold shares in street name for customers have the authority to vote on certain “routine” proposals when they have not received instructions from beneficial owners. Under NASD rules, such brokers are precluded from exercising their voting discretion with respect to the approval and adoption of non-routine matters, such as the amendment to the Hologic charter and the issuance of shares of Hologic common stock in the merger, the approval of the Hologic, Inc. Senior Executive Short-Term Incentive Plan or the approval of the amendment to Hologic’s Second Amended and Restated 1999 Equity Incentive Plan. Therefore, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote such shares with respect to the approval of these non-routine proposals.

Stock Ownership of Hologic Executive Officers and Directors

On [ ], 2007, the Hologic record date, executive officers and directors of Hologic and their affiliates beneficially owned and were entitled to vote approximately [ ] shares of Hologic common stock (excluding exercisable options). These shares represent approximately [ ]% of the aggregate voting power of Hologic shares entitled to vote at the Hologic special meeting.

Votes Required to Approve Hologic Proposals

Each of the Hologic proposals to be considered at the Hologic special meeting requires the vote percentage described below. You may vote for or against any or all of the proposals submitted at the Hologic special meeting or abstain from voting.

Required Vote for Hologic Charter Amendment (Proposal 1). The affirmative vote of at least a majority of the outstanding shares of Hologic common stock entitled to vote on the proposal, is required to approve the

135

##### Table of Contents

amendment to the Hologic charter. Consequently, an abstention from voting or a broker non-vote on Proposal 1 will have the effect of a vote against Proposal 1.

Required Vote for Issuance of Hologic Common Stock in the Merger (Proposal 2). The approval of the issuance of shares of Hologic common stock to Cytyc stockholders in the merger requires the affirmative vote of a majority of the votes cast in person or by proxy at the Hologic special meeting. Abstentions and broker non-votes are not deemed to be votes cast. Accordingly, assuming a quorum is present, an abstention or a failure to vote, including broker non-votes, will have no effect in determining whether the issuance of shares of Hologic common stock in the merger will be approved.

Required Vote for the Hologic, Inc. Senior Executive Short-Term Incentive Plan (Proposal 3). The approval of the Hologic, Inc. Senior Executive Short-Term Incentive Plan requires the affirmative vote of a majority of the votes cast in person or by proxy at the Hologic special meeting. Abstentions and broker non-votes are not deemed to be votes cast. Accordingly, assuming a quorum is present, the abstention or failure to vote, including broker non-votes, will have no effect in determining whether the Hologic, Inc. Senior Executive Short-Term Incentive Plan will be approved.

Required Vote for the Amendment to the Hologic, Inc. Second Amended and Restated 1999 Equity Incentive Plan (Proposal 4). The approval of the amendment to the Hologic’s Second Amended and Restated 1999 Equity Incentive Plan requires the affirmative vote of a majority of the votes cast in person or by proxy at the Hologic special meeting. Abstentions and broker non-votes are not deemed to be votes cast. Accordingly, assuming a quorum is present, the abstention or failure to vote, including broker non-votes, will have no effect in determining whether the amendment to the Hologic’s Second Amended and Restated 1999 Equity Incentive Plan will be approved.

Required Vote for Adjournment of the Hologic Special Meeting (Proposal 5). The approval of any adjournment of the Hologic special meeting, including, if necessary, to solicit additional proxies if there are not sufficient votes for any of the foregoing proposals requires the affirmative vote of a majority of the votes cast in person or by proxy, whether or not a quorum is present at the Hologic special meeting.

Each of Proposal 1 and Proposal 2 are conditioned upon the other and the approval of each such proposal is a condition to the completion of the merger. Neither the issuance of Hologic common stock in connection with the merger nor the amendment the Hologic charter will take place or be effective unless both of these proposals are approved by the Hologic stockholders. Therefore, the merger cannot be completed without the approval of both Proposal 1 and Proposal 2.

Voting Procedures—Stockholders of Record and Beneficial Owners

You are a stockholder of record if your shares of Hologic common stock are registered directly in your own name with Hologic’s transfer agent, American Stock Transfer and Trust Company, Inc. (“AST”). You are a beneficial owner if a brokerage firm, bank, trustee or other agent (called a “nominee”) holds your stock. This is often called ownership in “street name” because your name does not appear in the records of AST.

Revocation of Proxies

You have the power to revoke your proxy at any time before your proxy is voted at the Hologic special meeting. Your proxy can be revoked in one of four ways:

| • |  | you can send a signed notice of revocation;

| • |  | you can grant a new, valid proxy by executing a new proxy card bearing a later date;

| • |  | you can vote at a later time by telephone or through the Internet; or

| • |  | if you are a holder of record, you can attend the Hologic special meeting (or, if the special meeting is adjourned or postponed, attend the adjourned or postponed meeting) and vote in person which will automatically cancel any proxy previously given, but your attendance alone will not revoke any proxy previously given.

If you choose either of the first two methods, your notice of revocation or new proxy must be received by Hologic’s corporate secretary no later than the beginning of the Hologic special meeting or, if the special meeting is adjourned or postponed, before the adjourned or postponed meeting is actually held.

If your shares are held in “street name,” you may change your vote by submitting new voting instructions to your broker or nominee.

Solicitation of Proxies

This solicitation is made on behalf of the Hologic board of directors and Hologic will pay the costs of soliciting and obtaining proxies, including the cost of reimbursing banks and brokers for forwarding proxy materials to their principals. Proxies may be solicited, without extra compensation, by Hologic’s officers and employees by mail, telephone, fax, personal interviews or other methods of communication. Hologic has engaged MacKenzie Partners, Inc. to assist it in the distribution and solicitation of proxies at a fee of approximately $15,000, plus expenses. Hologic and Cytyc will also reimburse brokers and other custodians, nominees and fiduciaries for their expenses in sending these materials to you and getting your voting instructions.

Do not send any stock certificates with your proxy cards.

THE CYTYC SPECIAL MEETING

The Cytyc board of directors is using this joint proxy statement/prospectus to solicit proxies from the holders of shares of Cytyc common stock on the Cytyc record date for use at the special meeting of Cytyc stockholders. Cytyc is first mailing this joint proxy statement/prospectus and accompanying form of proxy to Cytyc stockholders on or about [ ], 2007.

Date, Time and Place

The special meeting of Cytyc stockholders will be held on [ ], 2007 at [ ] a.m., local time, at The Hilton Boston Logan Airport, 85 Terminal Road, Boston, Massachusetts 02128.

Purpose of the Cytyc Special Meeting

At the Cytyc special meeting, Cytyc stockholders will be asked to:

| 1. | adopt the merger agreement and the transactions contemplated thereby, including the merger; and

| 2. | if submitted to a vote of Cytyc stockholders, approve an adjournment of the Cytyc special meeting, including, if necessary, to solicit additional proxies in favor of the proposal to adopt the merger agreement if there are not sufficient votes for that proposal at the time of the meeting, as described in “Proposal to Adjourn Cytyc Special Meeting” beginning on page 142.

Board Recommendations

The Cytyc board of directors has unanimously determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and fair to and in the best interests of Cytyc and the Cytyc stockholders and unanimously recommends that the Cytyc stockholders use the proxy card to vote “FOR” the proposal to adopt the merger agreement and the transactions contemplated thereby, including the merger, and “FOR” the proposal to approve the adjournment, including, if necessary, in order to solicit additional proxies in favor of the adoption of the merger agreement.

Cytyc Record Date; Shares Entitled to Vote

The Cytyc board of directors has fixed the close of business on [ ], 2007, as the Cytyc record date for the Cytyc special meeting. Accordingly, only holders of record of Cytyc common stock as of the close of business on the Cytyc record date will be entitled to notice of, and to vote at, the Cytyc special meeting or any adjournment or postponement thereof. As of the Cytyc record date, an aggregate of [ ] shares of Cytyc common stock were issued and outstanding. The holders of Cytyc common stock are entitled to one vote per share on any proposal presented at the Cytyc special meeting.

Shares of Cytyc common stock held by Cytyc as treasury shares and shares of Cytyc common stock held by its subsidiaries will not be entitled to vote.

Stock Ownership of Directors and Executive Officers

On [ ], 2007, the Cytyc record date, directors and executive officers of Cytyc and their respective affiliates owned and were entitled to vote [ ] shares of Cytyc common stock, or approximately [ ]% of the shares of Cytyc common stock outstanding on that date. To Cytyc’s knowledge, the directors and executive officers of Cytyc and their respective affiliates intend to vote their shares of Cytyc common stock in favor of all Cytyc proposals at the Cytyc special meeting.

Quorum Requirement

The presence in person or by proxy of at least a majority of the voting power of the shares of Cytyc common stock issued and outstanding and entitled to vote at the Cytyc special meeting is necessary to establish a quorum

139

##### Table of Contents

for the transaction of business at the Cytyc special meeting. Abstentions and broker “non-votes” are counted as present or represented for purposes of determining the presence or absence of a quorum. A “non-vote” occurs when a broker holding shares for a beneficial owner votes on one proposal, but does not vote on another proposal because, in respect of such other proposal, the broker does not have discretionary voting power and has not received instructions from the beneficial owner.

Under NASD rules, brokers who hold shares in street name for customers have the authority to vote on certain “routine” proposals when they have not received instructions from beneficial owners. Under NASD rules, such brokers are precluded from exercising their voting discretion with respect to the approval and adoption of non-routine matters, such as the merger agreement. Therefore, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote such shares with respect to the approval of these non-routine proposals.

An automated system administered by Cytyc’s transfer agent tabulates the votes. The vote on each matter submitted to stockholders is tabulated separately. Abstentions and broker “non-votes” are included in the number of shares present or represented for purposes of quorum, but are not considered as shares voting or as votes cast with respect to any matter presented at the Cytyc special meeting.

Votes Required to Approve Cytyc Proposals

Required Vote for Adoption of Merger Agreement (Proposal 1). The affirmative vote of a majority of the outstanding shares of Cytyc common stock entitled to vote is required to adopt the merger agreement and the transactions contemplated thereby, including the merger. Consequently, an abstention from voting or a broker non-vote on Proposal 1 will have the effect of a vote against Proposal 1.

Adoption of the merger agreement and the transactions contemplated thereby, including the merger, by the requisite vote of the Cytyc stockholders is required to complete the merger.

Required Vote for Adjournment of the Cytyc Special Meeting (Proposal 2). Stockholder approval of any adjournment of the Cytyc special meeting, including, if necessary, to solicit additional proxies if there are not sufficient votes for the foregoing proposal, requires the affirmative vote of a majority of the votes cast by stockholders present in person or by proxy, whether or not a quorum is present at the meeting. Abstentions and broker non-votes will have no effect on the vote on Proposal 2.

Voting of Proxies

By Mail. A proxy card is enclosed for your use. To submit your proxy by mail, Cytyc asks that you sign and date the accompanying proxy and, if you are a stockholder of record, return it as soon as possible in the enclosed postage-paid envelope or according to the instructions provided in the proxy card. If the envelope is missing, please see the instructions on your proxy card. If you hold your shares in “street name”, please refer to your proxy card or the information provided to you by your bank, broker, custodian or record holder. When the accompanying proxy is returned properly executed, the shares of Cytyc common stock represented by it will be voted at the Cytyc special meeting in accordance with the instructions contained in the proxy.

If proxies are returned properly executed without indication as to how to vote, the Cytyc common stock represented by each such proxy will be considered to be voted in favor of all matters for consideration at the Cytyc special meeting as follows: “FOR” the proposal to adopt the merger agreement and the transactions contemplated thereby, including the merger, and “FOR” the proposal to approve the adjournment, including, if necessary, in order to solicit additional proxies in favor of the adoption of the merger agreement.

There are no voting agreements in place in respect of any outstanding shares of Cytyc common stock entitled to vote at the Cytyc special meeting.

If you choose either of the first two methods, your notice of revocation or new proxy must be received by Cytyc’s corporate secretary no later than the beginning of the Cytyc special meeting or, if the special meeting is adjourned or postponed, before the adjourned or postponed meeting is actually held.

If your shares are held in “street name,” you may change your vote by submitting new voting instructions to your broker or nominee.

Solicitation of Proxies

All costs of this solicitation of proxies will be borne by Cytyc. In addition to solicitations by mail, certain of Cytyc’s directors, officers and regular employees, without additional remuneration, may solicit proxies in person

141

##### Table of Contents

or by telephone or telegraph. Brokers, custodians and fiduciaries will be requested to forward proxy soliciting material to the owners of Cytyc common stock held in their names, and Cytyc will reimburse them for their reasonable out-of-pocket costs. Solicitation by Cytyc officers and employees may also be made of some Cytyc stockholders in person or by mail, telephone or telegraph following the original solicitation. In addition, Cytyc has engaged Morrow & Co., Inc. to assist it in the distribution and solicitation of proxies at a fee of $25,000, plus expenses.

Do not send any stock certificates with your proxy cards. If Cytyc stockholders adopt the merger agreement at the Cytyc special meeting, the other conditions to closing are satisfied and the merger is completed, the exchange agent will mail transmittal forms with instructions for the surrender of stock certificates for shares of Cytyc common stock as soon as practicable after completion of the merger.

Householding

In accordance with notices sent to Cytyc stockholders who share a single address and own their Cytyc shares through a bank, broker or other holder of record, Cytyc is sending only one proxy statement to that address unless it received contrary instructions from any stockholder at that address. This “householding” practice reduces Cytyc’s printing and postage costs. Cytyc stockholders may request or discontinue householding, or may request a separate copy of the proxy statement. Cytyc stockholders who wish to either discontinue or begin householding should contact their bank, broker or other record holder. Any householded stockholder may request prompt delivery of a copy of the proxy statement by visiting the Investor Information section of Cytyc’s website, www.cytyc.com, or may write to Cytyc at Investor Relations, 250 Campus Drive, Marlborough, Massachusetts 01752.

PROPOSAL TO ADJOURN CYTYC SPECIAL MEETING

The Cytyc stockholders are being asked to consider and vote upon a proposal to approve an adjournment of the special meeting, if necessary, including adjournments to permit further solicitation of proxies in favor of the proposal to adopt the merger agreement and the transactions contemplated thereby, including the merger.

If a quorum is not present at the Cytyc special meeting, Cytyc stockholders may be asked to vote on the proposal to adjourn the Cytyc special meeting to solicit additional proxies. If a quorum is present at the Cytyc special meeting, but there are not sufficient votes at the time of the special meeting to approve the proposal to adopt the merger agreement, Cytyc stockholders may also be asked to vote on the proposal to approve the adjournment of the special meeting to permit further solicitation of proxies in favor of that proposal.

If the adjournment proposal in submitted for a vote at the Cytyc special meeting, and if the Cytyc stockholders vote to approve the adjournment proposal, the meeting will be adjourned to enable the Cytyc board of directors to solicit additional proxies in favor of the proposal to adopt the merger agreement. If the adjournment proposal is approved, and the Cytyc special meeting is adjourned, the Cytyc board of directors will use the additional time to solicit additional proxies in favor of the proposal to adopt the merger agreement, including the solicitation of proxies from stockholders that have previously voted against the proposal to adopt the merger agreement. Among other things, approval of the adjournment proposal could mean that, even though Cytyc may have received proxies representing a sufficient number of votes against the proposal to adopt the merger agreement to defeat it, management could present the adjournment proposal for a vote of stockholders and thereby cause the Cytyc special meeting to be adjourned without a vote on the proposal to adopt the merger agreement and seek during that period of adjournment to convince the holders of those shares to change their votes to vote in favor of the proposal to adopt the merger agreement.

Cytyc’s board of directors believes that if the number of shares of Cytyc common stock voting in favor of the proposal to adopt the merger agreement is insufficient to approve that proposal, it is in the best interests of Cytyc’s stockholders to enable Cytyc’s board of directors, for a limited period of time, to continue to seek to obtain a sufficient number of additional votes in favor of the proposal.

HOLOGIC CHARTER AMENDMENT

At the Hologic special meeting, Hologic stockholders will be asked to approve the amendment (described below) of Hologic’s certificate of incorporation, as amended, which is referred to as the Hologic charter. The amendment will increase the number of authorized shares of Hologic common stock from 90,000,000 shares to 300,000,000 shares. As a condition to the completion of the merger, the Hologic stockholders must approve the amendment to the Hologic charter described in this section. Annex H to this joint proxy statement/prospectus contains the complete text of the proposed amendment to the Hologic charter, which you are urged to read in its entirety. See “Comparison of Stockholder Rights,” beginning on page 158. If the merger is not completed for any reason, Hologic’s board of directors will abandon the amendment described in this section and the amendment will be of no force and effect.

Increase of Authorized Common Stock

Under the Hologic charter, 90,000,000 shares of common stock are currently authorized. On [ ], 2007, the Hologic record date, approximately [ ] shares of Hologic common stock were issued and outstanding (not counting shares held in Hologic’s treasury).

To complete the merger, assuming conversion of all of Cytyc’s outstanding 2.25% Senior Convertible Notes due 2024, Hologic expects that approximately 64.8 million shares of Hologic common stock will be required to be issued to holders of shares of Cytyc common stock based on the number of shares of Cytyc common stock outstanding as of May 31, 2007 and that approximately 14.1 million shares of Hologic common stock will be required to be reserved for issuance under Cytyc options and other Cytyc equity-based awards.

Accordingly, the shares of Hologic common stock currently authorized under the Hologic charter will not be sufficient to complete the merger. Hologic therefore asks Hologic stockholders to approve the proposed amendment, which will change Article FOURTH of the Hologic charter to increase the number of authorized shares of Hologic common stock from 90,000,000 to 300,000,000 shares.

The increased number of authorized shares will give Hologic sufficient shares to complete the merger. At present, Hologic has no plans to issue shares for any other purpose, other than in connection with Hologic’s acquisition of BioLucent, Inc., pursuant to that certain Agreement and Plan of Merger dated as of June 20, 2007 by and among Hologic, Bravo Transition, Inc., and BioLucent, Inc. See “Summary—Recent Developments” beginning on page 8. Hologic believes, however, that it is desirable to have additional shares available for other corporate purposes that might arise in the future. For example, such shares could be used for acquisitions or to raise capital or to effect a stock split.

Whether any future issuance of shares unrelated to the merger would be submitted for stockholder vote depends upon the nature of the issuance, legal and stock exchange requirements and the judgment of the board of directors of the combined company at the time.

APPROVAL OF THE HOLOGIC, INC. SENIOR EXECUTIVE SHORT-TERM INCENTIVE PLAN

The Hologic, Inc. Senior Executive Short-Term Incentive Plan (STIP) was approved by the board of directors, upon recommendation of Hologic’s compensation committee, on June 25, 2007, subject to stockholder approval. Hologic is submitting the STIP for stockholder approval as required by Section 162(m) of the Code. If the STIP is approved by stockholders and terms therein are satisfied, then the payment of bonus awards under the STIP to the chief executive officer and the three other executive officers (other than principal financial officer) whose compensation is described each year in the summary compensation table of Hologic’s proxy statement (the covered employees) will be fully deductible as qualified performance-based compensation under Section 162(m). The STIP will be effective for determination of annual bonuses for the next fiscal year beginning on October 1, 2007. The following summary of the STIP should be read in conjunction with, and is qualified in its entirety by reference to, the complete text of the STIP, which is attached to this joint proxy statement/prospectus as Annex J.

143

##### Table of Contents

Summary of the STIP

The STIP provides objective performance-based awards for covered employees, subject to a maximum limit, as described in more detail below. Amounts paid under the STIP are intended to qualify as “qualified performance-based compensation,” which is excluded from the $1.0 million limit on deductible compensation set forth in Section 162(m) of the Code.

Administration. The STIP will be administered by the compensation committee appointed by the board of directors, which is authorized to designate as participants, and grant awards to, employees of Hologic who are covered employees. The compensation committee must be comprised of at least such number of directors as is required from time to time to satisfy the performance-based compensation exception provided for under Section 162(m) of the Code, each of whom must be an “outside director” within the meaning of Section 162(m).

Under the STIP, the compensation committee may designate participants and establish performance targets and target awards for each participant not later than 90 days after the beginning of a calendar year or fiscal year of Hologic, or such other period designated by the compensation committee, provided such performance targets and target awards are established before 25% of such period has elapsed. The performance targets may relate to the attainment of specified levels of one or more of the following measures, as defined below: economic value added; earnings before interest, taxes, depreciation and amortization; adjusted earnings before interest, taxes, depreciation and amortization; earnings before interest and taxes; earnings per share; operating income; adjusted operating income; income before income taxes; adjusted income before income taxes; net income; adjusted net income; operating margin return on equity; return on assets; revenue; and total shareholder return.

Shortly after the end of each performance period, the compensation committee must certify whether or not the performance targets have been achieved. The compensation committee has the right, in its sole discretion, to reduce the amount of the award to any participant to reflect the compensation committee’s assessment of the participant’s individual performance or for any other reason. These awards are payable in cash as soon as practicable thereafter.

To receive payment of an award, the participant must have remained in Hologic’s continuous employ through the end of the applicable performance period. However, if (i) Hologic terminates a participant’s employment other than for cause; (ii) a participant terminates his or her employment for good reason; or (iii) a participant becomes permanently disabled or dies during a performance period, the participant or his or her estate shall be awarded, unless his or her employment agreement provides otherwise, a pro rata portion of the award earned for the performance period. The compensation committee has the right, in its sole discretion, to reduce the amount of the award to reflect the compensation committee’s assessment of the participant’s individual performance prior to the applicable termination event or for any other reason. Unless otherwise specifically defined in an employment agreement or a benefit plan document, a determination as to whether a participant’s employment has been terminated for cause, for good reason or due to permanent disability shall be made by the compensation committee in its sole discretion.

Maximum Award. The STIP provides that the maximum award to any participant for any performance period is determined by multiplying a participant’s salary by a factor of four. As of the date of this joint proxy statement/prospectus, the highest salary of any participant was $510,000. As such, the maximum dollar amount of compensation that could be payable to any participant for any performance period under the STIP is $2.04 million.

Adjustments. In the event that, during a performance period, any recapitalization, reorganization, merger, acquisition, divestiture, consolidation, spin-off, combination, liquidation, dissolution, sale of assets or other similar corporate transaction or event, or any other extraordinary event, occurs, or any other event or circumstance occurs that has the effect, as determined by the compensation committee in its sole and absolute discretion, of distorting the applicable performance targets, including, without limitation, changes in accounting

144

##### Table of Contents

standards, the compensation committee may, to the extent consistent with Section 162(m), adjust or modify, in its sole and absolute discretion, the calculation of the performance targets, to the extent necessary to prevent reduction or enlargement of participants’ awards under the STIP for such performance period attributable to such transaction, circumstance or event.

Transfer Restrictions. The rights of a participant with respect to any award under the STIP are not transferable other than by will or the laws of descent and distribution. No award under the STIP will be construed as giving any employee a right to continued employment with Hologic.

Amendment. The board of directors may at any time alter, amend, suspend or terminate the STIP in whole or in part; provided, however, that no alteration or amendment will be effective without the approval of Hologic’s stockholders if their approval is required by law.

AMENDMENT TO HOLOGIC’S SECOND AMENDED AND RESTATED

1999 EQUITY INCENTIVE PLAN

Description of the Proposed Amendment

The stockholders of Hologic are being asked to consider and vote upon a proposal to approve an amendment to Hologic’s Second Amended and Restated 1999 Equity Incentive Plan, which is referred to as the 1999 Plan, at the Hologic special meeting to increase the number of shares of Hologic common stock available for issuance under the 1999 Plan by an additional 4,000,000 shares effective upon completion of the merger.

Currently the 1999 Plan provides that the maximum aggregate number of shares of Hologic common stock available for issuance under the 1999 Plan is 600,000 shares, plus an annual increase to be made on the first day of each fiscal year equal to the lesser of (i) 2 1/2% of the Issued Shares (as defined below) on the last day of the immediately preceding fiscal year; (ii) 1,000,000 shares; or (iii) an amount determined by the Hologic board of directors. As of May 31, 2007, since the adoption of the 1999 Plan in March 1999 and taking into account the annual adjustments to the maximum number of shares available for issuance under the 1999 Plan, there have been an aggregate of 7,660,000 shares authorized to be issued under the 1999 Plan, of which 4,209,751 shares have been issued, 2,416,371 shares are reserved for issuance pursuant to outstanding awards, and 1,033,878 shares are available for future issuances.

As a result of the merger, the board of directors of Hologic believes that the combined company, which will be a much larger company with significantly more employees, will need additional shares of common stock available for awards under the 1999 Plan to attract and retain employees and directors to provide an incentive for them to assist the combined company in achieving long-range performance goals, and to enable them to participate in the long-term growth of the combined company. Accordingly, on June 25, 2007, upon the recommendation of Hologic’s compensation committee, the board of directors unanimously approved, subject to stockholder approval, an amendment to Section 5(a) of the 1999 Plan to provide that an additional 4,000,000 shares of common stock of Hologic will be available for issuance under the 1999 Plan effective upon completion of the merger. If the amendment is approved by Hologic stockholders and the merger between Hologic and Cytyc is completed, the first sentence of Section 5(a) of the 1999 Plan will be deleted in its entirety and replaced with the following:

“Effective on the effective time of the merger between the Corporation and Cytyc Corporation pursuant to that certain Agreement and Plan of Merger, dated as of May 20, 2007, by and among Hologic, Inc., Cytyc Corporation and Nor’easter Corp., subject to adjustment under subsection (b), the maximum aggregate number of shares of common stock available for issuance under the Plan is 600,000 shares, plus (A) an annual increase to be made on the first day of each fiscal year equal to the lesser of (i) 2 1/2% of the Issued Shares (as defined below) on the last day of the immediately preceding fiscal year, (ii) 1,000,000 shares, or (iii) an amount determined by the board of directors, plus (B) 4,000,000 shares.”

145

##### Table of Contents

The amendment to the 1999 Plan will become effective if it is approved by Hologic stockholders at the Hologic special meeting, but only if the merger contemplated by the merger agreement is completed. Under the merger agreement, approval of the amendment to the 1999 Plan by Hologic stockholders is not a condition to the obligations of the parties to complete the merger. Accordingly, even if the amendment to the 1999 Plan is not approved by Hologic stockholders at the special meeting, the parties will be obligated to complete the merger if the closing conditions to the merger are satisfied.

If the amendment to the 1999 Plan is not approved by Hologic stockholders, the 1999 Plan will continue in effect in its current form. In connection with the merger, Hologic is assuming any grants outstanding under Cytyc’s 2004 Omnibus Plan and, if the 1999 Plan is not approved by Hologic stockholders, Hologic may determine to assume Cytyc’s 2004 Omnibus Plan in connection with the merger, and may continue to grant equity awards to former Cytyc employees on an as-converted basis, in accordance with the mergers and acquisitions exemption to the equity compensation plan stockholder approval requirement under applicable Nasdaq listing standards. An aggregate of 12,250,000 shares of Cytyc common stock have been reserved for issuance under Cytyc’s 2004 Omnibus Plan and, as of June 22, 2007, an aggregate of 12,250,000 shares have been authorized to be issued under the plan, of which 912,082 shares have been issued, 8,709,943 shares are reserved for issuance pursuant to outstanding awards, and 2,627,975 shares are available for future issuances. Any awards made pursuant to Cytyc’s 2004 Omnibus Plan after the effective time of the merger would be made in shares of common stock of Hologic on an as-converted basis in accordance with the terms of Cytyc’s 2004 Omnibus Plan. If the amendment to the 1999 Plan is approved by the Hologic stockholders, it is not expected that any further awards will be made under Cytyc’s 2004 Omnibus Plan.

The following summary of the 1999 Plan, as amended, is qualified by its entirety to the complete text of the Second Amended and Restated 1999 Equity Incentive Plan, as amended, a copy of which is attached to this joint proxy statement/prospectus as Annex K. Other than the changes described above to increase the authorized number of shares of Hologic common stock issuable under the 1999 Plan upon the effective time of the merger, the material terms and conditions of the 1999 Plan will not change.

Purpose. The 1999 Plan was approved by Hologic’s stockholders in March 1999 and amendments to the 1999 Plan were approved by Hologic’s stockholders in February 2004 and in February 2006. The purposes of the 1999 Plan are to attract and retain employees and directors to provide an incentive for them to assist Hologic in achieving long-range performance goals, and to enable them to participate in the long-term growth of Hologic.

Effective Date. The amendment to the 1999 Plan will become effective at the effective time of the merger, if it is approved by Hologic stockholders.

Term. The term of the 1999 Plan expires on March 3, 2009.

Awards Under the Plan. Awards under the 1999 Plan may be made in the form of:

| • |  | stock options, which may be either incentive stock options or non-qualified stock options;

| • |  | restricted stock;

| • |  | restricted stock units;

| • |  | stock appreciation rights either in tandem with an option or alone and unrelated to an option, or SARs;

| • |  | performance shares;

| • |  | award shares;

| • |  | other stock-based awards; or

| • |  | any combination of the foregoing.

Eligible Participants. All employees, and in the case of awards other than incentive stock options, directors of Hologic or any affiliate (as that term is defined in the 1999 Plan) capable of contributing significantly to the successful performance of Hologic, other than a person who has irrevocably elected not to be eligible, are eligible to participate in the 1999 Plan.

Administration. The 1999 Plan is currently administered by the compensation committee of Hologic’s board of directors. The compensation committee serves at the pleasure of Hologic’s board of directors which can, at its sole discretion, discharge any member of the compensation committee, appoint additional new members in substitution for those previously appointed and/or fill vacancies regardless of how they are caused. The board of directors of Hologic has the authority to adopt, alter and repeal administrative rules, guidelines and practices governing the operation of the 1999 Plan and to interpret provisions of the Plan. The board of directors may delegate, to the extent permitted by applicable law, to the compensation committee the power to make awards to participants and all determinations under the 1999 Plan with respect thereto.

Securities to be Offered. If the amendment to the 1999 Plan is approved by Hologic stockholders and the merger between Cytyc and Hologic becomes effective, the 1999 Plan, as amended, would provide that the maximum aggregate number of shares of common stock available for issuance under the 1999 Plan is 600,000 shares, plus (A) an annual increase to be made on the first day of each fiscal year equal to the lesser of (i) 2 1/2% of the Issued Shares (as defined below) on the last day of the immediately preceding fiscal year, (ii) 1,000,000 shares, or (iii) an amount determined by Hologic’s board of directors, plus (B) 4,000,000 shares. “Issued Shares” means the number of shares of Hologic’s common stock outstanding on the last day of the immediately preceding fiscal year, plus any shares reacquired by Hologic during the fiscal year that ends on that date. The shares of common stock available for issuance under the 1999 Plan are subject to adjustment for any stock dividend, recapitalization, stock split, stock combination or certain other corporate reorganizations.

Shares issued may consist in whole or in part of authorized but unissued shares or treasury shares. Shares subject to an award that expires or is terminated unexercised or is forfeited for any reason or settled in a manner that results in fewer shares outstanding than were initially awarded will again be available for award under the 1999 Plan. The maximum number of shares which may be granted to an individual in a fiscal year is limited to 1,000,000 shares. As of May 31, 2007, an aggregate of 7,660,000 shares of common stock are authorized for issuance under the 1999 Plan, of which 1,033,878 shares are available for future awards under the 1999 Plan. The closing price of Hologic’s common stock on the Nasdaq Global Select Market on June 27, 2007 was $55.45.

Nonqualified and Incentive Stock Options. Subject to the provisions of the 1999 Plan, the board of directors may award incentive stock options and nonqualified stock options and determine the number of shares to be covered by each option, the option price therefore and the conditions and limitations applicable to the exercise of the option. Each option shall be exercisable at such times and subject to such terms and conditions as the board of directors may specify in the applicable award or thereafter. The board of directors may provide for the automatic award of an option upon the delivery of shares to Hologic in payment of an option for up to the number of shares so delivered.

The terms and conditions of incentive stock options shall be subject to and comply with Section 422 of the Code and any regulations thereunder. No incentive stock option granted under the 1999 Plan may be granted more than ten years after the effective date of the 1999 Plan and no such grant may be exercisable more than ten years from the date of grant (five years after the date of grant for incentive stock options granted to holders of more than ten percent of the common stock). Incentive stock options shall be granted only to employees of Hologic and shall be transferable by the optionee only by the laws of descent and distribution, and shall be exercisable only by the employee during his or her lifetime.

The exercise price of options granted under the 1999 Plan may not be less than the fair market value of the common stock on the date of grant. Incentive stock options may be granted to holders of more than 10% of Hologic’s outstanding voting capital stock only at an exercise price of at least 110% of the fair market value of such stock on the date of grant.

Options Granted to Non-Employee Directors. The 1999 Plan provides that, unless otherwise determined by the board of directors, each director of Hologic who is not an employee of Hologic or affiliated with any holder of more than 5% of the outstanding voting stock of Hologic shall automatically be granted a nonqualified option to acquire 50,000 shares of common stock as of the date he or she is first elected to the board of directors or, with respect to such directors serving on the board of directors as of the effective date of the 1999 Plan, as of the date of Hologic’s 1999 Annual Meeting. In each case, the option price for such options will be the fair market value of the common stock on the date of grant and the expiration date shall be the tenth anniversary thereof. The compensation committee has the discretion to determine the terms, including the vesting schedule of the award. Under the compensation committee’s current practice, each such nonqualified option will become exercisable in 20% installments beginning on January 1 of the first year after the grant date, and on January 1 of each year thereafter, until such option is fully exercisable on January 1 of the fifth year following the grant date.

Furthermore, the 1999 Plan provides that, unless otherwise determined by the board of directors, each director of Hologic who is not an employee of Hologic and who has served as a director for six months shall automatically be granted a nonqualified option to acquire 8,000 shares of common stock as of January 1 of each year. The option price of these automatically granted options is the fair market value of the common stock on such date and the expiration date will be the tenth anniversary thereof. Under the compensation committee’s current practice, each of these options are exercisable in equal six month installments over two years after the date of grant.

In addition, the board of directors may provide for such other terms and conditions of these options as it may determine, as shall be set forth in the applicable option agreements, including, without limitation, acceleration of exercise upon a change of control of Hologic, termination of the options, and the effect on such options of the death, retirement or other termination of service as a director of the optionholder. Under the terms of the 1999 Plan, the Hologic board of directors may also grant additional awards to the non-employee directors.

Restricted Stock. Subject to provisions of the 1999 Plan, the board of directors may grant shares of restricted stock to participants, with such restricted periods and other conditions as the board of directors may determine and for no cash consideration or such minimum consideration as may be required by applicable law. During the restricted period, unless otherwise determined by the board of directors, stock certificates evidencing the restricted shares will be held by Hologic and may not be sold, assigned, transferred, pledged or otherwise encumbered, except as permitted by the board of directors. At the expiration of the restricted period, Hologic will deliver such certificates to the participant or, if the participant has died, to the beneficiary designed by the participant.

Restricted Stock Units. Subject to provisions of the 1999 Plan, the board of directors may grant restricted stock unit awards. A restricted stock unit is a contractual promise to issue shares at a specified future date, subject to fulfillment of vesting conditions specified by the board of directors. A restricted stock unit award carries no voting or dividend rights or other rights associated with stock ownership. A restricted stock unit award may be settled in common stock, cash, or in any combination of common stock and/or cash; provided, however, that a determination to settle a restricted stock unit award in whole or in part in cash shall be made by the board of directors in its sole discretion.

Stock Appreciation Rights. Subject to the provisions of the 1999 Plan, the board of directors may award SARs in tandem with an option (at or after the award of the option) or alone and unrelated to an option. A SAR entitles the holder to receive from Hologic an amount equal to the excess, if any, of the fair market value of the common stock over the reference price. SARs granted in tandem with an option will terminate to the extent that the related option is exercised, and the related option will terminate to the extent that the tandem SARs are exercised.

Performance Shares. Subject to the provisions of the 1999 Plan, the board of directors may grant performance shares to participants in the form of grants of shares of common stock. Performance shares are earned over a period of time (a performance cycle) selected by the board of directors from time to time. There

148

##### Table of Contents

may be more than one performance cycle in existence at any one time and the duration of the performance cycles may differ from each other. Unless otherwise determined by the board of directors, the payment value of the performance shares will be equal to the fair market value of the common stock on the date the performance shares are earned or on the date the board of directors determines that the performance shares have been earned. The board of directors shall establish performance goals for each cycle for the purpose of determining the extent to which performance shares awarded for such cycle are earned. As soon as practicable after the end of a performance cycle, the board of directors shall determine the number of performance shares which have been earned on the basis of performance in relation to the established performance goals. Payment values of earned performance shares are distributed to the participant or, if the participant has died, to the beneficiary designated by the participant.

Stock Awards. Subject to the provisions of the 1999 Plan, the board of directors may award stock awards, which may be designated as award shares by the board of directors, subject to such terms, restrictions, conditions, performance criteria, vesting requirements and payment needs, if any, as the board of directors shall determine. Shares of common stock or other rights awarded in connection with a stock award shall be issued for no cash consideration or such minimum consideration as may be required by law.

General Provisions. Each award shall be evidenced by a written document delivered to the participant specifying the terms and conditions thereof and containing such other terms and conditions not inconsistent with the provisions of the 1999 Plan as the board of directors considers necessary or advisable. Each type of award may be made alone, in addition to, or in relation to any other type of award. The terms of each type of award need not be identical and the board of directors need not treat participants uniformly. The board of directors may amend, modify or terminate any outstanding award, including substituting therefor another award, changing the date of exercise or realization and converting an incentive stock option to a nonqualified stock option, provided that the participant’s consent to such action shall be required unless the board of directors determines that the action would not materially and adversely affect the participant.

The board of directors will determine whether awards granted pursuant to the 1999 Plan are settled in whole or in part in cash, common stock, other securities of Hologic, other property or such other methods as the board of directors may deem appropriate. The board of directors may permit a participant to defer all or any portion of a payment under the 1999 Plan. In the board of directors’ discretion, tax obligations required to be withheld in respect of an award may be paid in whole or in part in shares of common stock, including shares retained from such award. The board of directors will determine the effect on an award of the death, disability, retirement or other termination of employment of a participant and the extent to which and period during which the participant’s legal representative, guardian or designated beneficiary may receive payment of an award or exercise rights thereunder. Except as otherwise provided by the board of directors, awards under the 1999 Plan are not transferable other than as designated by the participant by will or by the laws of descent and distribution.

The board of directors in its discretion may take certain actions in order to preserve a participant’s rights under an award in the event of a change in control of Hologic, including (i) providing for the acceleration of any time period relating to the exercise or realization of the award, (ii) providing for the purchase of the award for an amount of cash or other property that could have been received upon the exercise or realization of the award had the award been currently exercisable or payable, (iii) adjusting the terms of the award in order to reflect the change in control, (iv) causing the award to be assumed, or new rights substituted therefor, by another entity, or (v) making such other provision as the board of directors may consider equitable and in the best interest of Hologic, provided that, in the case of an action taken with respect to an outstanding award, the participant’s consent to such action shall be required unless the board of directors determines that the action, taking into account any related action, would not materially and adversely affect the participant.

The board of directors of Hologic may amend, suspend or terminate the 1999 Plan or any portion thereof at any time; provided that no amendment shall be made without stockholder approval if such approval is necessary to comply with any applicable law, rules or regulations.

Benefits under the Plan. Pursuant to the terms of the 1999 Plan, as such terms will continue to be in effect following the amendment to the plan, each non-employee director is automatically granted a nonqualified option to acquire 50,000 shares of common stock as of the date he or she is first elected to the board of directors. In addition, each non-employee who has served as a director for six months is granted a nonqualified option to purchase 8,000 shares of common stock as of January 1 of each year. The exercise prices of these options will be 100% of the fair market value of Hologic’s common stock on the date of grant. Future awards under the 1999 Plan to executive officers and employees, and any additional future discretionary awards to non-employee directors in addition to those granted automatically pursuant to the grant formula, are discretionary and cannot be determined at this time.

In accordance with the terms of the 1999 Plan, each independent continuing Cytyc director that becomes a director of Hologic at the effective time of the merger will receive an automatic grant of options to purchase 50,000 shares of Hologic common stock in accordance with the terms of the 1999 Plan, regardless of whether the amendment to the 1999 Plan is approved. In connection with entering into the merger agreement, the parties agreed to treat all independent directors who will serve as directors of Hologic at the effective time of the merger similarly. Accordingly, subject to discretion and approval of the compensation committee of the board of directors of Hologic by Hologic stockholders, it is expected that each independent continuing Hologic director will be granted options to purchase 50,000 shares of common stock of Hologic under 1999 Plan at the effective time of the merger. The options to purchase 50,000 shares of Hologic common stock to be granted to all independent directors of Hologic at the effective time of the merger will become exercisable in 20% installments beginning on January 1 of the first year after the grant date, and on January 1 of each year thereafter, until such options are fully exercisable on January 1 of the fifth year following the grant.

The 1999 Plan also provides that each non-employee who has served as a director for six months is granted a nonqualified option to purchase 8,000 shares of common stock as of January 1 of each year. If the independent continuing Hologic directors receive their discretionary grant of options to purchase 50,000 shares of Hologic common stock, they have agreed to forego their automatic grant of options to purchase 8,000 shares of Hologic common stock that they would have otherwise received on January 1, 2008 pursuant to the terms of the 1999 Plan. The independent continuing Cytyc directors are not eligible for the automatic grant of options to purchase 8,000 shares under Hologic’s 1999 Plan because such persons would not have been serving as a Hologic director for a period of six months before January 1, 2008.

United States Federal Income Tax Consequences

The following general discussion of the Federal income tax consequences of the issuance and exercise of options granted under the 1999 Plan is based upon the provisions of the Code as in effect on the date hereof, current regulations thereunder and existing administrative rulings of the Internal Revenue Service. This discussion is not intended to be a complete discussion of all of the Federal income tax consequences of the 1999 Plan or of all of the requirements that must be met in order to qualify for the tax treatment described herein. Changes in the law and regulations may modify the discussion, and in some cases the changes may be retroactive. No information is provided as to state tax laws. In addition, because tax consequences may vary, and certain exceptions to the general rules discussed herein may be applicable, depending upon the personal circumstances of individual holders of securities, each holder of an award should consider his personal situation and consult with his tax advisor with respect to the specific tax consequences applicable to him. The 1999 Plan is not qualified under Section 401 of the Code, nor is it subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended. The tax treatment of each kind of award under the 1999 Plan is as follows:

Incentive Stock Options. Incentive stock options granted under the 1999 Plan are intended to qualify as incentive stock options under Section 422 of the Code.

A participant generally will not recognize taxable income upon the grant or exercise of an incentive stock option. Under certain circumstances, however, there may be alternative minimum tax or other tax consequences,

150

##### Table of Contents

as described below. If an option holder does not make a “disqualifying disposition” (as defined below), then the option holder will not recognize any taxable income until shares are sold or exchanged, and any gain recognized upon disposition of shares will be taxable as long-term capital gain. A “disqualifying disposition” means any disposition of shares acquired on the exercise of an incentive stock option where such disposition occurs within two years of the date the option was granted or within one year of the date the shares were transferred to the option holder. The use of the shares acquired pursuant to the exercise of an incentive stock option to pay the option exercise price under another stock option is treated as a disposition for this purpose.

In general, if the option holder makes a disqualifying disposition, then the excess of (a) the lesser of (i) the fair market value of the shares on the date of exercise or (ii) the amount realized upon disposition of the shares over (b) the option exercise price will be taxable to the option holder as ordinary income. In the case of a gift or certain other transfers, the amount of taxable ordinary income is not limited to the gain that would have resulted from a sale. Instead, it is equal to the excess of the fair market value of the shares on the date of exercise over the option exercise price. In the case of a disqualifying disposition, if the amount realized on disposition of the shares exceeds the fair market value of the shares on the date of exercise, the excess will be taxed as either long-term or short-term capital gain depending on the option holder’s holding period for the shares. The holding period for the shares generally would begin on the date the shares were acquired and would not include the period of time during which the option was held.

Certain option holders are subject to Section 16(b) of the Exchange Act upon their sale of shares of common stock. If an option holder is subject to Section 16(b), the date on which the fair market value of the shares is determined may similarly be postponed. The Treasury regulations have not yet been amended to conform with the most recent revision to Section 16(b). However, it is generally anticipated that the date on which the fair market value of the shares is determined will be the earlier of (i) the date six months after the date the stock option was granted, or, (ii) the first day on which the sale of the shares would not subject the individual to liability under Section 16(b). It is possible that the six-month period will instead run from the option holder’s most recent grant or purchase of common stock prior to his or her exercise of the stock option. On the determination date, the option holder will generally recognize ordinary taxable income in an amount equal to the excess of the fair market value of the shares of common stock at that time over the option exercise price.

Despite the general rule, in the case of a substantial risk of forfeiture, or in the case of recipients subject to Section 16(b) (if the determination date is after the date of exercise), the option holder may make an election pursuant to Section 83(b) of the Code, in which case the option holder will recognize ordinary taxable income at the time the stock option is exercised and not on the later date. In order to be effective, the Section 83(b) election must be made and filed with the IRS within 30 days after exercise.

In general, the fair market value of the shares on the date of exercise, less the exercise price, will be included in the option holder’s alternative minimum taxable income in the year the option is exercised. However, if in the same year, the shares are disposed of at a lower price, then alternative minimum taxable income is calculated using this lower price instead of the shares’ fair market value on the date of exercise. The application of the alternative minimum tax rules for option holders subject to Section 16(b) or who receive shares that are not “substantially vested” is more complex and may depend upon whether such holders are entitled to and make a Section 83(b) election. Because of the many adjustments that apply to the computation of the alternative minimum tax, it is not possible to predict the application of such tax to any particular option holder. An option holder may owe alternative minimum tax even though he has not disposed of the shares or otherwise received any cash with which to pay the tax. The alternative minimum tax rate is higher than the rate applicable to long-term capital gains.

Hologic will not be entitled to any deduction with respect to the grant or exercise of incentive stock options. In addition, no deduction will be allowed to Hologic upon the disposition of stock acquired upon the exercise of an incentive stock option, unless the disposition is a disqualifying disposition. In the case of a disqualifying disposition, Hologic generally will be entitled to a deduction equal to the amount of compensation income that is recognized by the employee as a result of the disqualifying disposition.

151

##### Table of Contents

Nonqualified Stock Options. A recipient of a nonqualified stock option generally will not recognize any income for federal tax purposes with respect to the option until the option is exercised. At that time, subject to certain limited exceptions, the recipient will recognize ordinary income in an amount equal to the excess of the fair market value of the shares on the date acquired over the option exercise price.

The application of the tax rules to an option holder who receives shares that are subject to a substantial risk of forfeiture (for example, if the shares must be returned to Hologic if the recipient does not work for Hologic for a period of time, if any, specified in the award) are more complex. In that case, the recipient generally will not recognize income until the date the shares are no longer subject to the substantial risk of forfeiture, unless a Section 83(b) election (described below) is made.

Certain option holders are subject to Section 16(b) of the Exchange Act upon their sale of shares of common stock. If an option holder is subject to Section 16(b), the date on which the fair market value of the shares is determined may similarly be postponed. The Treasury regulations have not yet been amended to conform with the most recent revision to Section 16(b). However, it is generally anticipated that the date on which the fair market value of the shares is determined will be the earlier of (i) the date six months after the date the stock option was granted, or (ii) the first day on which the sale of the shares would not subject the individual to liability under Section 16(b). It is possible that the six month period will instead run from the option holder’s most recent grant or purchase of common stock prior to his or her exercise of the stock option. On the determination date, the option holder will generally recognize ordinary taxable income in an amount equal to the excess of the fair market value of the shares of common stock at that time over the option exercise price.

Despite the general rule, in the case of a substantial risk of forfeiture, or in the case of recipients subject to Section 16(b) (if the determination date is after the date of exercise), the option holder may make an election pursuant to Section 83(b) of the Code, in which case the option holder will recognize ordinary taxable income at the time the stock option is exercised and not on the later date. In order to be effective, the Section 83(b) election must be made and filed with the IRS within 30 days after exercise.

When an option recipient recognizes income, Hologic will generally be entitled to a compensation deduction for federal income tax purposes in an amount equal to the taxable income recognized by the recipient, provided that Hologic reports the income on a timely provided and filed Form W-2 or 1099, whichever is applicable.

Upon a subsequent sale of shares acquired by the exercise of a nonqualified stock option, a recipient generally will recognize capital gain (or loss) equal to the amount by which the selling price of the shares exceeds (or is exceeded by) their fair market value on the date of exercise. The capital gain or loss will be short-term or long-term depending upon how long the shares were held. Any capital gain or loss would be long-term if the holding period for the shares was more than twelve months. The holding period for the shares generally would begin on the date the shares were acquired, and would not include the period of time during which the option was held.

Stock Appreciation Rights. A recipient of a SAR will not be considered to receive any income at the time an SAR is granted, nor will Hologic be entitled to a deduction at that time. Upon the exercise of an SAR, the holder will have ordinary income equal to the cash received upon the exercise. At that time, Hologic will be entitled to a tax deduction equal to the amount of ordinary income realized by the holder.

Restricted Stock and Performance Shares. The recipient of restricted stock or performance shares will be treated in the same manner as a person who has exercised a nonqualified stock option, as described above, for which Hologic has imposed restrictions on the shares received, and for which the exercise price is either zero or a nominal amount. In general, this means that the holder may either wait until the restrictions have elapsed (or the performance goals have been met), and then pay tax at ordinary income tax rates, based upon the fair market value of the shares at that time, or he or she can file a Section 83(b) election, and pay tax based on the fair market value of the shares at the time they are received. Again, Hologic will get a deduction that corresponds to the income recognized by the recipient.

152

##### Table of Contents

Restricted Stock Unit Awards. The grant of a restricted stock unit award will not result in income for the grantee or in a deduction for Hologic. Upon the lapse of the restrictions of a restricted stock unit, the grantee will recognize ordinary income and Hologic will be entitled to a deduction measured by the fair market value of the shares plus any cash received.

Stock Awards. A person who receives a stock award that includes common stock will be treated, with regard to such common stock, in the same manner as a person who has exercised a nonqualified stock option, as described above. In general, this means that the holder will have taxable income at the time the shares are received if they are not subject to restrictions, or as described in the preceding paragraph for restricted stock, if they are subject to restrictions. The tax treatment of a stock award that consists of other rights will depend on the provisions of the award. It may be immediately taxable if there are no restrictions on the receipt of the cash or other property that the stock award represents, or the tax consequences may be deferred if the receipt of cash or other property for the stock award is restricted, or subject to vesting or performance goals. In those situations in which a participant receives property subject to restrictions, the participant may wish to make a Section 83(b) election, as described above. At the time that the holder of the stock award has ordinary income, Hologic will be entitled to a tax deduction equal to the amount of ordinary income realized by the holder.

Deductibility of Awards. Section 162(m) of the Code places a $1 million annual limit on the compensation deductible by Hologic paid to certain of its executives. The limit, however, does not apply to performance-based compensation. Hologic believes that awards under the 1999 Plan will qualify for the performance-based compensation exception to the deductibility limit.

Equity Compensation Plan Information

(2) | Includes the following plans: 1997 Employee Equity Incentive Plan and 2000 Acquisition Equity Incentive Plan. A description of each of these plans is as follows:

1997 Employee Equity Incentive Plan. The purposes of the 1997 Employee Equity Incentive Plan, the 1997 Plan, adopted by the board of directors in May 1997, are to attract and retain key employees, consultants and advisors, to provide an incentive for them to assist us in achieving long-range performance goals, and to enable such person to participate in Hologic’s long-term growth. In general, under the 1997 Plan, all employees, consultants, and advisors who are not executive officers or directors are eligible to participate in the 1997 Plan. The 1997 Plan is administered by a committee consisting of at least three members of the board appointed by the board of directors. Participants in the 1997 Plan are eligible to receive non-qualified stock options, stock appreciation rights, restricted stock and performance shares. A total of 2,200,000 shares of common stock were reserved for issuance under the 1997 Plan. Of the shares reserved for issuance under the 1997 Plan, options to purchase 502,784 shares have been granted and are outstanding. In September 2005, Hologic’s board of directors determined that no further awards would be made under this plan and cancelled all remaining shares, 166,084, available for issuance under the 1997 Plan that are not subject to outstanding stock option awards.

2000 Acquisition Incentive Plan. The purpose of the 2000 Acquisition Equity Incentive Plan, the 2000 Plan, adopted by the board of directors in April 2001, is to attract and retain (a) employees, consultants and advisors of newly acquired businesses who have been or are being hired as employees, consultants or advisors of Hologic or any of its consolidated subsidiaries, and (b) employees, consultants and advisors of Hologic who have or are anticipated to provide significant assistance in connection with the acquisition of a newly acquired business or its integration with Hologic, and to provide such persons an incentive for them to achieve long-range performance goals, and to enable them to participate in Hologic’s long-term growth. In general, under the 2000 Plan, only employees, consultants and advisors who are not officers or directors of Hologic are eligible to participate in the 2000 Plan. The 2000 Plan is administered by the board of directors or, at its option, a committee consisting of at least three members of the Board appointed by the board of directors. Participants in the 2000 Plan are eligible to receive non-qualified stock options, stock appreciation rights, restricted stock and performance shares. A total of 1,600,000 shares of common stock were reserved for issuance under the 2000 Plan. Of the shares reserved for issuance under the 2000 Plan, options to purchase 360,820 shares have been granted and are outstanding. In September 2005, the board of directors determined that no further awards would be made under this plan and cancelled all remaining shares, 417,704, available for issuance under the 2000 Plan that are not subject to outstanding stock option awards.

PROPOSAL TO ADJOURN HOLOGIC SPECIAL MEETING

The stockholders of Hologic are being asked to consider and vote upon a proposal to approve an adjournment of the special meeting, if necessary, including adjournments to permit further solicitation of proxies in favor of each of the proposals to amend the Hologic charter, approve the issuance of shares of Hologic common stock in the merger, approve the Hologic, Inc. Senior Executive Short-Term Incentive Plan and approve of the amendment to Hologic’s Second Amended and Restated 1999 Equity Incentive Plan.

If a quorum is not present at the Hologic special meeting, Hologic stockholders may be asked to vote on the proposal to adjourn the Hologic special meeting to solicit additional proxies. If a quorum is present at the Hologic special meeting, but there are not sufficient votes at the time of the special meeting to approve one or more of the proposals, Hologic stockholders may also be asked to vote on the proposal to approve the adjournment of the special meeting to permit further solicitation of proxies in favor of the other proposals; provided, however, that if (i) there are sufficient votes to approve the Hologic charter and the issuance of the shares of Hologic common stock in the merger and (ii) all of the other conditions to the merger are satisfied, Hologic will not delay completion of the merger to solicit additional proxies in favor of the proposals to approve the Hologic, Inc. Senior Executive Short-Term Incentive Plan or the amendment to Hologic’s Second Amended and Restated 1999 Equity Incentive Plan.

If the adjournment proposal is submitted for a vote at the Hologic special meeting, and if the stockholders vote to approve the adjournment proposal, the meeting will be adjourned to enable the Hologic board of directors to solicit additional proxies in favor of one or more proposals. If the adjournment proposal is approved, and the Hologic special meeting is adjourned, the Hologic board of directors will use the additional time to solicit additional proxies in favor of any of the proposals to be presented at the special meeting, including the solicitation of proxies from stockholders that have previously voted against the relevant proposal. Among other things, approval of the adjournment proposal could mean that, even though Hologic may have received proxies representing a sufficient number of votes against a proposal to defeat it, management could present the adjournment proposal for a vote of stockholders and thereby cause the Hologic special meeting to be adjourned without a vote on the proposal and seek during that period to convince the holders of those shares to change their votes to vote in favor of the proposal.

Hologic’s board of directors believes that, if the number of shares of common stock voting in favor of any of the proposals presented at the Hologic special meeting is insufficient to approve a proposal, it is in the best interests of Hologic’s stockholders to enable Hologic’s board of directors, for a limited period of time, to continue to seek to obtain a sufficient number of additional votes in favor of the proposal.

HOLOGIC BYLAWS AMENDMENT

In connection with entering into the merger agreement, the Hologic board of directors approved amending and restating Hologic’s current bylaws, which are referred to as the Hologic bylaws. The amendments to the Hologic bylaws will become effective no later than, but only upon, the effective time of the merger. If the merger is not completed for any reason, the changes described in this section will be of no force and effect. The following discussion describes the material changes to the Hologic bylaws and is qualified in its entirety by reference to the amended and restated bylaws of Hologic attached as Annex I to this joint proxy statement/prospectus, which contains the complete text of the Hologic bylaws that will take effect only upon completion of the merger. Additional changes to Hologic’s bylaws made in connection with entering into the merger agreement are described under “Comparison of Stockholders Rights” beginning on page 158. Unless otherwise discussed, the current Hologic bylaws do not contain provisions discussed below and such amendments will be additions.

Board Composition.

The amended Hologic bylaws will provide that at the effective time of the merger, the Hologic board of directors will be comprised of eleven directors. The board of directors of Hologic will consist of six continuing Hologic directors, four designated by the continuing Hologic directors, each of whom will be independent and

155

##### Table of Contents

two persons who are not independent, and five continuing Cytyc directors, three designated by the continuing Cytyc directors, each of whom will be independent and two persons who are not independent.

Before the annual meeting of stockholders to be held in 2009 (the “2009 Annual Meeting”) all vacancies resulting from the cessation of service of an independent continuing Hologic director will be filled by a nominee proposed by a majority of the remaining continuing Hologic directors and all vacancies resulting from the cessation of service of an independent continuing Cytyc director will be filled by a nominee proposed by a majority of the remaining continuing Cytyc directors. All remaining vacancies shall be filled by a nominee proposed and selected by the nominating and corporate governance committee of the board of directors. The terms “continuing Hologic directors” and “continuing Cytyc directors” shall mean, respectively, the directors of Hologic or Cytyc, as the case may be, who were selected to be directors of Hologic as of the effective time of the merger by Hologic or Cytyc, as the case may be, prior to the effective time of the merger, and any additional directors of Hologic who take office after the effective time of the merger who are nominated, or proposed to the nominating and corporate governance committee, by a majority of the continuing Hologic directors or the continuing Cytyc directors, as the case may be. Any continuing Hologic director or continuing Cytyc director who is then serving as a Hologic director shall be nominated by the nominating and corporate governance committee for election as a Hologic director at Hologic’s annual meeting of stockholders to be held in 2008, subject to the fiduciary duties of the members of the nominating and corporate governance committee. For the 2009 Annual Meeting and thereafter, the combined company’s nominations for persons to serve on the board of directors shall be determined by the nominating and corporate governance committee. Prior to the 2009 Annual Meeting, any amendment of or change to the provisions of the amended Hologic bylaws providing for board composition shall require the affirmative vote of at least 75% of the full board of directors.

Board Committees.

The amended Hologic bylaws provide that the board of directors shall designate a compensation committee, an audit committee, and a nominating and corporate governance committee.

Indemnification.

The amended Hologic bylaws provide that Hologic will indemnify any person who was or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a director or officer of Hologic or, while a director or officer of Hologic, is or was serving at the request of Hologic as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, where the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such person in connection with such proceeding. Hologic will indemnify any person seeking indemnification in connection with a proceeding brought by that person only if the proceeding (or part thereof) was authorized by the Hologic board of directors. The current Hologic bylaws permit indemnification of officers and directors, but do not require Hologic to provide such persons with indemnification.

Chief Executive Officer.

The amended Hologic bylaws provide that the chief executive officer will be an officer of Hologic as appointed by the board of directors. Unless there is a chairman of the board, or the board of directors votes otherwise, when present, the chief executive officer will preside at meetings of the stockholders and the board of directors. The board of directors will designate the duties and powers of such office.

Chairman Emeritus.

The amended Hologic bylaws also provide that the board of directors may appoint one or more positions for former directors designated as “director emeritus” or “chairman emeritus.” Former directors filling these positions will function as advisors to the board of directors and be able to attend all meetings of the board of directors, but will have no right to vote as a director on any matter.

COMPARISON OF STOCKHOLDER RIGHTS

Hologic and Cytyc are both incorporated under Delaware law. Any differences, therefore, in the rights of Hologic stockholders and Cytyc stockholders arise primarily from differences in their respective certificates of incorporation and bylaws. Upon completion of the merger, the charter and bylaws of Hologic will be identical in all respects to the Hologic charter and Hologic bylaws after giving effect to the proposed Hologic charter amendment and Hologic bylaw amendments contemplated by the merger agreement and described in “Hologic Charter Amendment” and “Hologic Bylaws Amendment,” beginning on pages 143 and 155, respectively. Consequently, after the effective time of the merger, the rights of the former Cytyc stockholders will be determined by reference to the amended Hologic charter and amended Hologic bylaws. The following table compares the material differences between the current rights of Cytyc stockholders under the Cytyc certificate of incorporation and bylaws (which are referred to as the Cytyc certificate of incorporation and Cytyc bylaws, respectively), and the current rights of Hologic stockholders under the Hologic charter and Hologic bylaws, as well as the rights that those stockholders will have as Hologic stockholders under the amended Hologic charter and amended Hologic bylaws following the completion of the merger. This summary does not purport to be complete and is qualified in its entirety by reference to Cytyc’s certificate of incorporation and bylaws, Hologic’s charter and bylaws, Hologic’s and Cytyc’s respective rights plans and the relevant provisions of Delaware law.

Limitation on Liability |  | The Cytyc certificate of incorporation provides that no director (including any advisory director) will be personally liable to the corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for: • any breach of the director’s duty of loyalty to Cytyc or its stockholders; • acts or omissions not in good faith or which involve intentional misconduct or knowing violation of the law; • any violation of Section 174 of the DGCL relating to the unlawful payment of a dividend or unlawful stock purchases or redemptions; or • any transaction from which the director derived an improper personal benefit.

The indemnification agreements are intended to provide the maximum protection permitted by Delaware law with respect to the indemnification of directors. Hologic may also enter into similar agreements with certain of its officers who are not also directors. Hologic maintains directors’ and officers’ liability insurance.

In addition, the Cytyc certificate of incorporation provides that the corporation has the power to purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the corporation or another enterprise against any expense, loss or liability incurred by such person in any such capacity, whether or not the corporation would have the power to indemnify him against such liability under Delaware law. The Cytyc certificate of incorporation provides that if Delaware law is amended to expand further the indemnification permitted to indemnities covered by the certificate of incorporation, then Cytyc shall indemnify such persons to the fullest extent permitted by Delaware law, as so amended. The Cytyc certificate of incorporation provides that if Cytyc is merged into or consolidated with another corporation and it is not the surviving corporation, the surviving corporation shall assume the obligations of Cytyc under the Cytyc certificate of incorporation with respect to any proceeding arising out of or relating to matters occurring prior to the date of such merger or consolidation. |  |  |  |
Dividends |  | Under Delaware law, except as set forth in the certificate of incorporation, a corporation is generally permitted to declare and pay dividends out of surplus (defined as the excess, if any, of net assets over capital) or, if no surplus exists, out of net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year.

Stockholder Rights Plan |  | Cytyc has adopted a stockholder rights plan pursuant to a rights agreement between Cytyc and Computershare Trust Company, N.A. (successor to EquiServe Trust Company, N.A., which was a successor to BankBoston, N.A.), as rights agent. In connection with the adoption of the rights plan, on August 6, 1997, the board of directors declared a dividend of one preferred stock purchase right for each outstanding share of common stock to stockholders of record at the close of business on September 5, 1997. Each right entitles the holder, subject to the terms and conditions in the rights plan, to purchase from the company a unit consisting of one one-hundredth of a share of Series A junior participating preferred stock, $0.01 par value, at a purchase price of $110 per unit, subject to adjustment. The rights are represented by Cytyc’s common stock certificates and are not immediately exercisable. The rights only become exercisable and begin to trade separately from shares of common stock after the occurrence of certain events as described in the rights plan. If the rights have become exercisable and certain triggering events described in the rights plan have occurred, all holders of rights, other than the acquiring person or group, would be entitled to acquire shares of Cytyc’s common stock at a 50% discount to the then-current market price. In addition, if |  |  |  | Hologic’s board of directors has adopted a stockholder rights plan. As a result, Hologic issued one preferred share purchase right for each outstanding share of common stock. One preferred share purchase right will be issued for each additional share of common stock that the company issues. The rights become exercisable if, without the prior approval of Hologic’s board of directors, a person or group acquires 15% or more of Hologic’s outstanding common stock or commences or announces a tender or exchange offer which would result in such ownership. Each right that becomes exercisable entitles the registered holder to purchase one half of one-thousandth of a share of the junior participating preferred stock at a purchase price of $60.00 per one-thousandth of a share, subject to adjustment. If, after the rights become exercisable, Hologic was to be acquired through a merger or other business combination transaction or 50% or more of the assets or earning power were sold, each right would permit the holder to purchase, for the purchase price, common stock of the surviving company having a market value of twice the purchase price. The rights expire on January 1, 2013, unless earlier redeemed or exchanged by Hologic. The purchase price payable and the shares of preferred stock issuable upon

The rights expire on September 5, 2007. In addition, Cytyc’s board of directors retains the authority to redeem, at $0.01 per right, the rights at any time until ten days following the acquisition by a person or group of 15% or more of the outstanding common stock. In addition, Cytyc’s board of directors retains the authority to redeem, at $0.01 per right, the rights at any time until ten days following the acquisition by a person or group of 15% or more of the outstanding common stock.

In addition, Hologic’s board of directors retains the authority to redeem, at $0.001 per right, the rights at any time prior to the acquisition by a person or group of 15% or more of the outstanding common stock. On May 20, 2007, in connection with the signing of the merger agreement, Hologic amended its rights plan to render it inapplicable to the merger agreement, merger and the other transactions contemplated thereby.
Certain Business Combinations / Anti –takeover Provisions |  | Under Delaware law, a corporation can elect not to be governed by Section 203 of the DGCL, which generally protects publicly held Delaware corporations from unfair transactions and tactics by persons who acquire large blocks of stocks without prior board approval. Cytyc has not made this election and is therefore subject to the restrictions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested” stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination or the transaction by which the person became an interested stockholder is approved in a prescribed manner.

Charter and Bylaws. Hologic’s charter and the amended Hologic charter include several other provisions in addition to the authorization of blank check preferred stock which may have the effect of making an unfriendly tender offer, proxy contest, merger or other change in control of Hologic more difficult. These

|  | benefit to the interested stockholder. Subject to exceptions, an “interested” stockholder is a person who, alone or together with his affiliates and associates, owns 15% or more of the corporation’s voting stock. These provisions could have the effect of delaying, deferring or preventing a change in control of Cytyc or reducing the price that certain investors might be willing to pay in the future for Cytyc common stock. |  | provisions are intended to enhance the likelihood of continuity and stability in the composition of Hologic’s board of directors and in the policies formulated by the board of directors and to discourage certain types of transactions that may involve a change in control. These provisions are also designed to reduce Hologic’s vulnerability to unsolicited acquisition proposals and to discourage certain tactics that may be used in proxy fights. These provisions, however, could have the effect of discouraging others from making tender offers for the shares of Hologic’s common stock and, as a consequence, they also may inhibit fluctuations in the market price of the shares of the common stock which could result from actual or rumored takeover attempts. Hologic’s charter and the amended Hologic charter contain a so-called “anti-greenmail” provision. This provision is intended to discourage speculators who accumulate beneficial ownership of a significant block of stock of a company and then, under the threat of making a tender offer or instigating a proxy contest or some other corporate disruption, succeed in extracting from the company a premium price to repurchase the shares acquired by the speculator. This tactic has become known as greenmail. The anti-greenmail provision prohibits Hologic from purchasing any shares of its common stock from a related person, who has beneficially owned such common stock or right to purchase such common stock for less than two years prior to the date of such purchase, at a per share price in excess of the fair market value at the time of the purchase unless the purchase is approved by the holders of two-thirds of the outstanding shares of Hologic’s common stock, excluding any votes cast by the related person. The term “related person” means any person (other than the

|  |  |  | company or a subsidiary of the company or a founder of the company) who acquires more than 5% of Hologic’s voting stock. Stockholder approval is not required for such purchases when the offer is made available on the same terms to all holders of shares of the common stock or when the purchases are effected on the open market. The Hologic charter also provides, and upon completion of the merger, the amended Hologic charter will provide, that the affirmative vote of the holders of 80% of the outstanding common stock is required to approve amendments to Hologic’s charter or to approve extraordinary transactions that are required to be approved by stockholders under Delaware law, including mergers, sales of substantially all of the Company’s assets and dissolution, if the actions are not approved by a majority of Hologic’s continuing directors. Another provision included in Hologic’s charter and the amended Hologic charter requires the board of directors to consider social, economic and other factors in evaluating whether certain types of corporate transactions proposed by another party are in the best interests of the company and its stockholders. These transactions include (i) the purchase or exchange of securities or property for any of Hologic’s outstanding equity securities; (ii) the merger or consolidation of Hologic with another corporation; and (iii) the purchase or other acquisition of all or substantially all of the company’s properties and assets. The authority of Hologic’s board of directors to issue authorized but unissued shares of common stock might be considered as having the effect of discouraging an attempt by another person or entity to effect a takeover or otherwise gain control of Hologic, since the issuance of additional shares of common stock would dilute the voting power of Hologic’s common stock then outstanding.

These provisions may preclude stockholders from making nominations for directors at an annual or special meeting of stockholders. Upon completion of the merger, the amended Hologic bylaws will provide that prior to the annual meeting of stockholders to be held in 2009, a vote of at least 75% of the full board of directors will be required to amend the provisions regarding board composition, as further described above in “Hologic Bylaws Amendment Board Composition” beginning on page 155. See also the description of the Rights Plan above under “Stockholders Rights Plan.” Section 203 of the DGCL. The Hologic charter subjects, and upon completion of the merger the amended Hologic charter will subject, the corporation to the restrictions on business combinations of Section 203 of the DGCL. This section prohibits publicly held Delaware corporations from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes certain mergers, asset sales and the other transactions resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, alone or together with his or her affiliates and associates, owns 15% or more of a corporation’s voting stock. The foregoing provisions could have the effect of delaying, deferring or preventing a change in control of Hologic or reducing the price that certain investors might be willing to pay in the future for shares of Hologic common stock.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements of Hologic have been prepared to give effect to the proposed merger of Hologic and Cytyc. The unaudited pro forma condensed combined balance sheet as of March 31, 2007, and the unaudited pro forma condensed combined statements of operations for the six months ended March 31, 2007 and the year ended September 30, 2006, are presented herein to reflect the proposed merger. The unaudited pro forma condensed combined balance sheet combines the unaudited condensed balance sheets of Hologic and Cytyc as of March 31, 2007 and gives effect to the merger as if it had been completed on that date. The unaudited pro forma condensed combined statements of operations for the six months ended March 31, 2007 combines the historical results of Hologic and the unaudited pro forma combined results of Cytyc and gives effect to the merger as if it had occurred on September 25, 2005. The unaudited proforma condensed combined statement of operations for the year ended September 30, 2006 combines the unaudited pro forma combined results of Hologic for the year ended September 30, 2006 and the unaudited pro forma combined results of Cytyc for the year ended December 31, 2006 and gives effect to the merger as if it occurred on September 25, 2005. Hologic’s unaudited pro forma condensed combined statement of operations for the year ended September 30, 2006 gives effect to Hologic’s July 2006 acquisitions of R2 Technology, Inc. and Suros Surgical Systems, Inc. as if they had occurred on September 25, 2005. Cytyc’s unaudited pro forma condensed combined statements of operations for the year ended December 31, 2006 and the six months ended March 31, 2007 gives effect to Cytyc’s April 2007 acquisition of the Adeza Biomedical Corporation as if it had occurred on January 1, 2006. Hologic and Cytyc have different fiscal year end dates. However, as the difference is less than 93 days, Cytyc’s results for the year ended December 31, 2006 have been used to prepare the unaudited pro forma condensed combined statement of operations for the year ended September 30, 2006, as permitted under Rule 11-02 of Regulation S-X. As a result, Cytyc’s results of operations for the three months ended December 31, 2006 are included in the unaudited pro forma condensed combined statements of operations for both the year ended December 31, 2006 and the six months ended March 31, 2007.

The unaudited pro forma condensed combined financial statements presented are based on the assumptions and adjustments described in the accompanying notes. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes and do not purport to represent what the financial position or results of operations would actually have been if the merger occurred as of the dates indicated or what such financial position or results will be for any future periods. The unaudited pro forma condensed combined financial statements are based upon the respective historical and pro forma consolidated financial information of Hologic and Cytyc, and should be read in conjunction with:

| • |  | the accompanying notes to the unaudited pro forma condensed combined financial statements;

| • |  | the separate historical consolidated financial statements of Hologic as of and for the six months ended March 31, 2007 included in Hologic’s quarterly report on Form 10-Q for the six months ended March 31, 2007, which is incorporated by reference into this joint proxy statement/prospectus;

| • |  | the separate historical consolidated financial statements of Hologic as of and for the year ended September 30, 2006 included in Hologic’s annual report on Form 10-K for the year ended September 30, 2006, which is incorporated by reference into this joint proxy statement/prospectus;

| • |  | the separate historical consolidated financial statements of Cytyc as of and for the three months ended March 31, 2007, including the purchase price allocation for Adeza Biomedical Corporation in note 2(a) included in Annex B of this joint proxy statement/prospectus under the heading “Cytyc Condensed Consolidated Financial Statements (Unaudited);” and

| • |  | the separate historical consolidated financial statements of Cytyc as of and for the year ended December 31, 2006 included in Annex B of this joint proxy statement/prospectus under the heading “Cytyc Consolidated Financial Statements.”

The unaudited pro forma condensed combined financial information was prepared using the purchase method of accounting. Based upon the terms of the merger, including the premium paid by Hologic of

174

##### Table of Contents

approximately 33% for Cytyc’s common stock and the cash portion of the merger consideration of $16.50 per share or approximately 36% of the merger consideration, and other factors, such as the composition of the combined company’s board of directors and senior management, Hologic is treated as the acquiror of Cytyc. Accordingly, we have adjusted the historical consolidated financial information to give effect to the impact of the consideration issued in connection with the merger. In the unaudited pro forma condensed combined balance sheet, Hologic’s cost to acquire Cytyc has been allocated to the assets acquired and liabilities assumed based upon management’s preliminary estimate of their respective fair values as of the date of the merger. Any differences between fair value of the consideration issued and the fair value of the assets and liabilities acquired will be recorded as goodwill. The amounts allocated to acquired assets and liabilities in the unaudited pro forma condensed combined financial statements are based on management’s preliminary valuation estimates. Definitive allocations will be performed and finalized based on certain valuations and other studies that will be performed by Hologic with the services of outside valuation specialists after the closing of the merger. Accordingly, the purchase price allocation adjustments and related amortization reflected in the following unaudited pro forma condensed combined financial statements are preliminary, have been made solely for the purpose of preparing these statements and are subject to revision based on a final determination of fair value after the closing of the merger. For example, if the value of the definite-lived intangible assets increased by 10%, annual pro forma income from continuing operations would decrease by $11,000.

The unaudited pro forma condensed combined statements of operations also include certain purchase accounting adjustments, including items expected to have a continuing impact on the combined results, such as increased depreciation and amortization expense on acquired tangible and intangible assets, increased interest expense on the assumed debt incurred to complete the merger, decreased interest income related to the assumed reduction in cash used to complete the merger, increased compensation expense related to Cytyc’s non-vested stock options assumed to be converted into Hologic stock options upon the completion of the merger and the tax impact related to these pro forma adjustments.

The unaudited pro forma condensed combined statements of income do not include the impacts of any revenue, cost or other operating synergies that may result from the merger or any related restructuring costs. Cost savings, if achieved, could result from material sourcing and elimination of redundant costs including headcount and facilities.

The unaudited pro forma condensed combined financial statements reflect the contemplated borrowings of $2,189,200 under the $2,350,000 term loan facilities described under “The Merger—Financing of the Merger.” Amounts borrowed under term loan facilities and the applicable interest rates have been estimated for the purposes of preparing these unaudited pro forma condensed combined financial statements and are subject to change based on the actual cash portion of the merger consideration, related fees and expenses and market changes that may result in a change in the actual interest rate applied to borrowings as compared to the rates assumed. For example, if the Libor rate increased by 10% as compared to the Libor rate assumed, annual pro forma income before provision for income taxes would decrease $12,000. Similarly, if the applicable rate applied to the Libor rate increased 25 basis points compared to the rate assumed annual pro forma income before provision for income taxes would decrease $5,500. The unaudited pro forma condensed combined financial statements do not reflect the impact of any re-financing of the debt incurred in connection with the merger, liquidity or other balance sheet repositioning that may be undertaken in connection with or subsequent to the merger.

The unaudited pro forma condensed combined financial statements do not reflect certain amounts resulting from the merger because we consider them to be of a non-recurring nature and are anticipated to be included in the income of Hologic within 12 months succeeding the transaction. These amounts include the estimated charge for acquired in-process research and development of approximately $282,900, the cost of revenue impact of approximately $39,000 for the write up of inventory to fair value and the reduction of deferred revenue of approximately $3,300 for amounts that would not represent a legal obligation at the close of the transaction. Hologic and Cytyc have just recently begun collecting information in order to formulate detailed integration

175

##### Table of Contents

plans to deliver planned synergies. However, any potential merger related synergies and/or cost savings as a result of the integration have not been included in the pro forma financial information.

Based on Hologic’s preliminary review of Cytyc’s summary of significant accounting policies disclosed in Cytyc’s financial statements, the nature and amount of any adjustments to the historical financial statements of Cytyc to conform their accounting policies to those of Hologic are not expected to be significant. Upon completion of the merger, further review of Cytyc’s accounting policies and financial statements may result in required revisions to Cytyc’s policies and classifications to conform to Hologic’s.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

(In thousands, except per share information)

1. | Basis of Presentation

The following unaudited pro forma condensed combined financial statements of Hologic have been prepared to give effect to the proposed merger of Hologic and Cytyc. The unaudited pro forma condensed combined balance sheet as of March 31, 2007, and the unaudited pro forma condensed combined statements of operations for the six months ended March 31, 2007 and the year ended September 30, 2006, are presented herein to reflect the proposed merger. The unaudited pro forma condensed combined balance sheet combines the unaudited condensed balance sheets of Hologic and Cytyc as of March 31, 2007 and gives effect to the merger as if it had been completed on that date. The unaudited pro forma condensed combined statements of operations for the six months ended March 31, 2007 combines the historical results of Hologic and the unaudited pro forma combined results of Cytyc and gives effect to the merger as if it had occurred on September 25, 2005. The unaudited proforma condensed combined statement of operations for the year ended September 30, 2006 combines the unaudited pro forma combined results of Hologic for the year ended September 30, 2006 and the unaudited pro forma combined results of Cytyc for the year ended December 31, 2006 and gives effect to the merger as if it occurred on September 25, 2005. Hologic’s unaudited pro forma condensed combined statement of operations for the year ended September 30, 2006 gives effect to Hologic’s July 2006 acquisitions of R2 Technology, Inc. and Suros Surgical Systems, Inc. as if they had occurred on September 25, 2005. Cytyc’s unaudited pro forma condensed combined statement of operations for the year ended September 30, 2006 and the six months ended March 31, 2007 gives effect to Cytyc’s April 2007 acquisition of the Adeza Biomedical Corporation as if it had occurred on January 1, 2006. Hologic and Cytyc have different fiscal year end dates. However, as the difference is less than 93 days, Cytyc’s results for the year ended December 31, 2006 have been used to prepare the unaudited pro forma condensed combined statement of operations for the year ended September 30, 2006, as permitted under Rule 11-02 of Regulation S-X. As a result, Cytyc’s results of operations for the three months ended December 31, 2006 are included in the unaudited pro forma condensed combined statements of operations for both the year ended December 31, 2006 and the six months ended March 31, 2007.

The unaudited pro forma condensed combined financial information was prepared using the purchase method of accounting. As discussed under “—Accounting Treatment” beginning on page 104, based upon the terms of the merger, including the premium paid by Hologic of approximately 33% for Cytyc’s common stock and the cash portion of the merger consideration of $16.50 per share or approximately 36% of the merger consideration, and other factors, such as the composition of the combined company’s board of directors and senior management, Hologic is treated as the acquiror of Cytyc. Accordingly, we have adjusted the historical consolidated financial information to give effect to the impact of the consideration issued in connection with the merger. In the unaudited pro forma condensed combined balance sheet, Hologic’s cost to acquire Cytyc has been allocated to the assets acquired and liabilities assumed based upon management’s preliminary estimate of their respective fair values as of the date of the merger. Any differences between fair value of the consideration issued and the fair value of the assets and liabilities acquired will be recorded as goodwill. The amounts allocated to acquired assets and liabilities in the unaudited pro forma condensed combined financial statements are based on management’s preliminary internal valuation estimates. Definitive allocations will be performed and finalized based on certain valuations and other studies that will be performed by Hologic with the services of outside valuation specialists after the closing of the merger. Accordingly, the purchase price allocation adjustments and related amortization reflected in the foregoing unaudited pro forma condensed combined financial statements are preliminary, have been made solely for the purpose of preparing these statements and are subject to revision based on a final determination of fair value after the closing of the merger. For example, if the value of the definite-lived intangible assets increased by 10%, annual pro forma income from continuing operations would decrease by $11,000.

##### Table of Contents

Hologic has secured a fully committed debt financing from Goldman Sachs Credit Partners L.P. for the cash portion of the merger consideration. For purposes of the unaudited condensed combined financial statements Hologic has assumed that it will borrow approximately $2,189,200 of the committed funding and use available cash of approximately $137,000 to finance the cash portion of the merger, repay amounts outstanding under Cytyc’s existing line of credit and pay merger related fees and expenses. Accordingly, additional interest expense has been recorded for such amounts using the borrowing rate under the firm commitment letter from Goldman Sachs Credit Partners L.P. of 7.11% (Libor rate as of June 2007 plus 1.75%). The reduction of interest income is based on the estimated reduction in cash available for investment of the combined entities.

(B) To adjust Cytyc’s inventory, property and equipment and deferred revenue to their estimated fair value. To record estimated depreciation expense related to the step up of property and equipment, primarily equipment under customer usage agreements with an estimated remaining useful life of 6 years. The cost of revenue impact of the write-up of inventory to fair value of $38,800 and reduction of deferred revenue of $3,400 for amounts that would not represent a legal obligation at the close of the transaction have been excluded from the pro forma condensed combined statement of income as they are non-recurring items which are anticipated to be included in the income of Hologic within the 12 months succeeding the transaction.

(C) To eliminate Cytyc’s existing goodwill, intangible assets, related deferred tax liability and pro forma combined amortization of the intangible assets.

(D) To record goodwill and $2,801,000 of acquired definite-lived intangible assets and related amortization based on expected future cash flows which Hologic has determined reflects the economic benefits which the intangible assets are expected to be utilized over a weighted average life of 15 years for both existing technology and marketing based intangibles. Based on the estimated value of these intangibles and their estimated useful lives, Hologic anticipates recording amortization expense of approximately $759,000 over the 5 years succeeding the close of the transaction. The estimated charge of $283,000 of acquired in-process research and development has been excluded from the pro forma condensed combined statement of income as it is a non-recurring item which is anticipated to be included in the income of Hologic within the 12 months succeeding the transaction.

(E) To record deferred taxes related to identified intangible assets and fair value adjustments, where required for step-up in basis for book purposes, at 40%, the estimated weighted average statutory tax rate.

(F) To eliminate the historical stockholders equity accounts of Cytyc.

(G) To record the issuance of Hologic common stock and to record the fair value of Cytyc’s stock options.

(H) To record incremental stock option compensation expense based on the fair value of Cytyc’s non-vested stock options assumed to be converted into Hologic stock options upon the completion of the merger.

(I) To record the tax benefit on pro forma adjustments to income related to the merger, to reflect the estimated weighted average statutory tax rate of 40%. Hologic has included the tax benefit related to the incremental stock-based compensation expense pro forma adjustment based on the estimate that the majority of the Cytyc unvested options are non-qualified stock options.

(J) To reflect the exchange ratio of 0.52 of a share of Hologic for each share of Cytyc. The impact of options issued in connection with the merger has been determined to be antidilutive.

(K) To eliminate interest expense included in Cytyc pro forma combined condensed statements of operations as all of Cytyc’s debt arrangements are being settled in connection with the merger.

(L) The pro forma condensed combined statements of operations do not reflect estimated charges related to change of control payments of approximately $15,000 and stock based compensation expenses for the acceleration of vesting of outstanding stock options for certain members of Cytyc executive management, such charges will be recorded by Cytyc in the period that the proposed merger is completed. The pro forma combined condensed statement of income also excluded a $1,500 charge related to a change of control payment for a certain executive officer of Hologic. This charge will be recorded by Hologic in the period that the proposed merger is completed.

Cytyc

Cytyc held its 2006 annual meeting of stockholders on May 2, 2006. If the merger agreement is adopted by the requisite vote of the Cytyc stockholders and the merger is completed, Cytyc will merge into wholly owned subsidiary of Hologic and, consequently, will not hold an annual meeting of its stockholders in 2007. Cytyc stockholders will be entitled to participate, as stockholders of the combined company, in the 2008 annual meeting of stockholders of the combined company.

If the merger agreement is not adopted by the requisite vote of the Cytyc stockholders or if the merger is not completed for any reason, Cytyc will hold an annual meeting of its stockholders in 2007.

In the event that Cytyc holds a 2007 annual meeting of its stockholders, stockholders interested in presenting a proposal for inclusion in Cytyc’s proxy statement and proxy relating to Cytyc’s 2007 annual meeting of stockholders may do so by following the procedures prescribed in Rule 14a-8 under the Exchange Act and Cytyc’s bylaws. Because the 2007 annual meeting date will represent a change of more than 30 days from the anniversary of Cytyc’s 2006 annual meeting, Cytyc will announce a new deadline for the receipt of any stockholder proposals submitted pursuant to Rule 14a-8 for inclusion in Cytyc’s proxy materials for the 2007 annual meeting. As required by Rule 14a-8, such new deadline will be a reasonable time before Cytyc begins to print and mail its proxy materials.

In addition, in accordance with the requirements for advance notice set forth in Cytyc’s bylaws, in order for a stockholder proposal submitted outside of Rule 14a-8 or a director nomination to be considered timely for the 2007 annual meeting, such proposal or nomination must be received by Cytyc’s Corporate Secretary by no earlier than the close of business on the 90th day before the 2007 annual meeting and not later than the close of business on the later of the 60th day prior to the 2007 annual meeting or the close of business on the 10th day following the day on which public announcement of the date of the 2007 annual meeting is first made by Cytyc. In the event that Cytyc holds a 2007 annual meeting of its stockholders, Cytyc will announce a new deadline for the receipt of any stockholder proposals submitted outside of Rule 14a-8 or a director nomination. Any notification to bring any proposal before the 2007 annual meeting must comply with the requirements of Cytyc’s bylaws.

ARTICLE 2

THE MERGER

Section 2.01 The Merger.

(a) At the Effective Time, Cyclone shall be merged with and into MergerSub in accordance with Delaware Law, at which time the separate existence of Cyclone shall cease, and MergerSub shall be the surviving corporation (the “Surviving Corporation”), and shall be a wholly owned, direct subsidiary of Hurricane.

(b) From and after the Effective Time, the Surviving Corporation shall possess all of the rights, privileges, powers and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of Cyclone and MergerSub, all as provided under Delaware Law.

Section 2.02 Effective Time. At the Closing the parties shall file a certificate of merger (the “Certificate of Merger”) with the Delaware Secretary of State in such form as is required by and executed and completed in accordance with the relevant provisions of Delaware Law and make all other filings or recordings required by Delaware Law to effect the Merger. The Merger shall become effective at such time (the “Effective Time”) as the Certificate of Merger is duly filed with the Delaware Secretary of State (or at such later time as Hurricane and Cyclone mutually agree and specify in the Certificate of Merger).

Section 2.03 Closing. Upon the terms and subject to the conditions set forth in Article 9, the closing of the Merger (the “Closing”) will take place as soon as practicable, but in no event later than five (5) Business Days, after the satisfaction or waiver of the conditions (excluding conditions that, by their nature, cannot be satisfied until the Closing), or such other time and date as the parties may agree to in writing. The Closing shall be held at the offices of Brown Rudnick Berlack Israels LLP in Boston, Massachusetts, unless another place is agreed to in writing by the parties hereto.

Section 2.04 Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof:

(a) subject to this Article 2, each share of Cyclone Stock issued and outstanding immediately prior to the Effective Time (other than shares to be cancelled in accordance with Section 2.04(b) and Dissenting Shares referred to in Section 2.11), shall be cancelled and converted into the right to receive (i) 0.52 (the “Exchange Ratio”) shares of Hurricane Stock (the “Stock Merger Consideration”) and (ii) $16.50 in cash

A-8

##### Table of Contents

without interest (the “Cash Merger Consideration” and, together with the Stock Merger Consideration and cash in lieu of fractional shares of Hurricane Stock as specified below, the “Merger Consideration”);

(b) each share of Cyclone Stock that is (i) held by Cyclone as treasury stock or (ii) owned by Hurricane or any Hurricane Subsidiary, in each case immediately prior to the Effective Time, shall be canceled and shall cease to exist, and no payment shall be made with respect thereof in accordance with this Article 2; and

(c) each share of common stock, par value $.01 per share, of MergerSub issued and outstanding immediately prior to the Effective Time shall remain issued, outstanding and unchanged as a validly issued, fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation.

Section 2.05 Surrender and Payment.

(a) Prior to the Effective Time, Hurricane shall designate its transfer agent, American Stock Transfer & Trust Company, or another bank or trust company reasonably satisfactory to Cyclone to act as the exchange agent hereunder (the “Exchange Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing shares of Cyclone Stock (the “Certificates”) or (ii) uncertificated shares of Cyclone Stock (the “Uncertificated Shares”). At the Effective Time, Hurricane shall deposit with the Exchange Agent, to be held in trust for the holders of Cyclone Stock, stock certificates (if such shares shall be certificated) representing shares of Hurricane Stock issuable pursuant to Section 2.04 in exchange for outstanding shares of Cyclone Stock and an amount of cash sufficient to deliver to the holders of Cyclone Stock (other than the Dissenting Shares) the aggregate Merger Consideration. From time to time after the Effective Time, Hurricane shall make available to the Exchange Agent, as needed, cash in amounts that are sufficient to pay cash in lieu of fractional shares pursuant to Section 2.07 and any dividends or other distributions pursuant to Section 2.05(f), in each case, to be paid in respect of the Certificates and the Uncertificated Shares. Promptly after the Effective Time, but in any event within ten (10) Business Days after the Effective Time, Hurricane shall send, or shall cause the Exchange Agent to send, to each holder of shares of Cyclone Stock at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Exchange Agent) for use in such exchange.

(b) Each holder of shares of Cyclone Stock shall be entitled to receive, upon (i) surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the aggregate Merger Consideration that such holder has a right to receive pursuant to Section 2.04. The shares of Hurricane Stock constituting part of such Merger Consideration, at Hurricane’s option, shall be in uncertificated book-entry form, unless a physical certificate is requested by a holder of shares of Cyclone Stock or is otherwise required under Applicable Law. As a result of the Merger, at the Effective Time, all shares of Cyclone Stock shall cease to be outstanding and each holder thereof shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration payable in respect thereof and any dividends or other distributions payable in respect thereof in accordance with Section 2.05(f).

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(d) At the Effective Time, the stock transfer books of Cyclone shall be closed and thereafter there shall be no further registration of transfers on the transfer books of Cyclone or the Surviving Corporation of the shares of Cyclone Stock which were outstanding immediately prior to such time. If, after the Effective

A-9

##### Table of Contents

Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration payable in respect thereof provided for, and in accordance with the procedures set forth, in this Article 2.

(e) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 2.05(a) that remains unclaimed by the holders of shares of Cyclone Stock six months after the Effective Time shall be returned to Hurricane, upon demand, and any such holder who has not exchanged shares of Cyclone Stock for the Merger Consideration in accordance with this Section 2.05 prior to that time shall thereafter look only to Hurricane for payment of the Merger Consideration, and any dividends and distributions with respect thereto, in respect of such shares without any interest thereon. Notwithstanding the foregoing, Hurricane shall not be liable to any holder of shares of Cyclone Stock for any amounts properly paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of shares of Cyclone Stock six years after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Applicable Law, the property of Hurricane, free and clear of any claims or interest of any Person previously entitled thereto.

(f) No dividends or other distributions with respect to securities of Hurricane constituting part of the Merger Consideration, and no cash payment in lieu of fractional shares as provided in Section 2.07, shall be paid to the holder of any Certificates not surrendered or of any Uncertificated Shares not transferred until such Certificates or Uncertificated Shares are surrendered or transferred, as the case may be, as provided in this Section 2.05. Following such surrender or transfer, Hurricane shall pay or shall cause the Exchange Agent to pay, without interest, to the Person in whose name the securities of Hurricane have been registered, (i) at the time of such surrender or transfer, the amount of any cash payable in lieu of fractional shares to which such Person is entitled pursuant to Section 2.07 and the amount of all dividends or other distributions with a record date after the Effective Time previously paid or payable on the date of such surrender with respect to such securities, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and prior to surrender or transfer and with a payment date subsequent to surrender or transfer payable with respect to such securities.

Section 2.06 Stock Options; Restricted Stock Units; Performance Shares; ESPP.

(a) As soon as practicable following the date of this Agreement, the Board of Directors of Cyclone (or, if appropriate, any committee thereof administering the Cyclone Stock Plans) shall adopt such resolutions or take such other actions as may be required to effect the following:

(i) each option to purchase shares of Cyclone Stock under any employee stock option or compensation plan or arrangement of Cyclone (a “Cyclone Stock Option”) outstanding immediately prior to the Effective Time shall be amended and converted into an option to acquire, on the same terms and conditions (giving effect to any applicable acceleration of vesting thereunder) as were applicable under such Cyclone Stock Option, the number of shares of Hurricane Stock (rounded down to the nearest whole share) equal to the sum of (x) the product of (A) the number of shares of Cyclone Stock subject to such Cyclone Stock Option and (B) the Exchange Ratio and (y) the product of (A) the number of shares of Cyclone Stock subject to such Cyclone Stock Option and (B) the Cash Portion Exchange Multiple, at an exercise price per share of Hurricane Stock (rounded up to the nearest whole cent) equal to the quotient obtained by dividing (1) the aggregate exercise price for the shares of Cyclone Stock subject to such Cyclone Stock Option by (2) the aggregate number of shares of Hurricane Stock to be subject to such Cyclone Stock Option after giving effect to the adjustments in this clause (i) (each, as so adjusted, an “Adjusted Option”);

(ii) each Cyclone Restricted Stock Unit outstanding immediately prior to the Effective Time shall be amended and converted into the right to receive, on the same terms and conditions (giving effect to any applicable acceleration of vesting thereunder) as were applicable under such Cyclone Restricted Stock Unit, the number of shares of Hurricane Stock (rounded down to the nearest whole share) equal

A-10

##### Table of Contents

to the sum of (x) the product of (A) the number of shares of Cyclone Stock subject to such Cyclone Restricted Stock Unit and (B) the Exchange Ratio and (y) the product of (A) the number of shares of Cyclone Stock subject to such Cyclone Restricted Stock Unit and (B) the Cash Portion Exchange Multiple (each, as so adjusted, an “Adjusted Restricted Stock Unit”);

(iii) each Cyclone Performance Share outstanding immediately prior to the Effective Time shall vest at the target award level in accordance with the terms and conditions applicable under such Cyclone Performance Share and holders thereof shall be entitled to receive the Merger Consideration on the same basis as all other shares of Cyclone Stock;

(iv) each share of Cyclone Stock deferred (a “Cyclone Share Unit”) under the Amended and Restated Director Compensation Method Plan (the “Director Compensation Plan”) shall be converted into, on the same terms and conditions (giving effect to any applicable acceleration of vesting thereunder) as are applicable under the Director Compensation Plan, a number of shares of Hurricane Stock (rounded down to the nearest whole share) equal to the sum of (x) the product of (A) the number of shares of Cyclone Stock subject to such Cyclone Share Unit and (B) the Exchange Ratio and (y) the product of (A) the number of shares of Cyclone Stock subject to such Cyclone Share Unit and (B) the Cash Portion Exchange Multiple (each, as so adjusted, an “Adjusted Share Unit”);

(v) holders of each share of Cyclone Stock accrued in 2007 for issuance to members of the Board of Directors of Cyclone on January 1, 2008 shall be entitled to receive the Merger Consideration on the same basis as all other shares of Cyclone Stock; and

(vi) prior to the Effective Time, Cyclone shall make any amendments to the terms of such stock option or compensation plans or arrangements that are necessary to give effect to the adjustments contemplated by this Section 2.06.

(b) As soon as practicable following the date of this Agreement, the Board of Directors of Cyclone (or, if appropriate, any committee of the Board of Directors of Cyclone administering the Cyclone ESPP), shall adopt such resolutions or take such other actions as may be required to provide that with respect to the Cyclone ESPP (i) each participant’s outstanding right to purchase shares of Cyclone Stock under the Cyclone ESPP shall terminate on the day immediately prior to the day on which the Effective Time occurs, provided that all amounts allocated to each participant’s account under the Cyclone ESPP as of such date shall thereupon be used to purchase from Cyclone whole shares of Cyclone Stock at the applicable price determined under the terms of the Cyclone ESPP for the then outstanding offering periods using such date as the final purchase date for each such offering period, and (ii) the Cyclone ESPP shall terminate immediately following such purchases of Cyclone Stock.

(c) The adjustments provided in Section 2.06(a) with respect to any Cyclone Stock Option to which Section 421(a) of the Code applies shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code. As soon as practicable following the Effective Time, Hurricane shall deliver to the holders of Adjusted Options, Adjusted Restricted Stock Units and Adjusted Share Units appropriate notices setting forth such holders’ rights pursuant to the respective Cyclone Stock Plans and the Contracts evidencing the grants of such Adjusted Options, Adjusted Restricted Stock Units or Adjusted Share Units, as the case may be, which shall provide, among other things, that such Adjusted Options, Adjusted Restricted Stock Units, Adjusted Share Units and Contracts have been assumed by Hurricane and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 2.06 after giving effect to the Merger).

(d) Except as otherwise contemplated by this Section 2.06 and except to the extent required under the respective terms of the Adjusted Options, Adjusted Restricted Stock Units or Adjusted Share Units, as the case may be, all restrictions or limitations on transfer and vesting with respect to such Adjusted Options, Adjusted Restricted Stock Units or Adjusted Share Units, to the extent that such restrictions or limitations shall not have already lapsed, and all other terms thereof, shall remain in full force and effect with respect to such Adjusted Options, Adjusted Restricted Stock Units or Adjusted Share Units after giving effect to the Merger and the assumption by Hurricane as set forth above.

A-11

##### Table of Contents

(e) Hurricane shall take such actions as are necessary for the assumption of Cyclone Stock Options, Cyclone Restricted Stock Units and Cyclone Share Units pursuant to this Section 2.06, including the reservation, issuance and listing of Hurricane Stock as is necessary to effectuate the transactions contemplated by this Section 2.06. Subject to receiving full cooperation from Cyclone and its independent registered public accounting firm, within one (1) Business Day of the Closing Date, Hurricane shall file with the SEC a registration statement on an appropriate form, or a post-effective amendment to a registration statement previously filed under the 1933 Act, with respect to the shares of Hurricane Stock subject to Adjusted Options, Adjusted Restricted Stock Units and Adjusted Share Units and, where applicable, shall use all commercially reasonable efforts to have such registration statement declared effective as soon as practicable following the Effective Time. With respect to those individuals, if any, who, subsequent to the Effective Time, will be subject to the reporting requirements under Section 16(a) of the 1934 Act, where applicable, Hurricane shall use all commercially reasonable efforts to administer Cyclone Stock Options and Cyclone Restricted Stock Units assumed pursuant to this Section 2.06 in a manner that complies with Rule 16b-3 promulgated under the 1934 Act.

(f) For purposes of this Agreement, “Cash Portion Exchange Multiple” means the quotient obtained by dividing (x) the Cash Merger Consideration by (y) the average of the per share closing sale prices of Hurricane Stock on The NASDAQ Stock Market (the “Nasdaq”) for the ten consecutive trading days ending on (and including) the date that is three (3) trading days prior to the Closing Date.

Section 2.07 Fractional Shares. No certificates, scrip or shares of Hurricane Stock representing fractional shares of Hurricane Stock or book-entry credit of the same shall be issued upon the surrender for exchange of Certificates or Uncertificated Shares, and such fractional share interests shall not entitle the owner thereof to vote or to have any rights as a stockholder of Hurricane by virtue of such fractional share interests. All fractional shares of Hurricane Stock that a holder of shares of Cyclone Stock would otherwise be entitled to receive as a result of the Merger shall be aggregated and if a fractional share results from such aggregation, such holder shall be entitled to receive, in lieu thereof, an amount in cash without interest determined by multiplying the closing sale price of a share of Hurricane Stock on the Nasdaq on the Closing Date by the fraction of a share of Hurricane Stock to which such holder would otherwise have been entitled. Hurricane shall deposit with the Exchange Agent the funds required to make the cash payments required by this Section 2.07 when and as needed.

Section 2.08 Withholding Rights. Hurricane, the Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 2 such amounts as Hurricane, the Surviving Corporation or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. If Hurricane, the Surviving Corporation or the Exchange Agent so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which Hurricane, the Surviving Corporation or the Exchange Agent made such deduction and withholding.

Section 2.09 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Hurricane, delivery by such Person of an agreement in a form reasonably satisfactory to Hurricane or, as Hurricane may reasonably deem necessary, the posting by such Person of a bond, in such reasonable amount as Hurricane may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the shares of Cyclone Stock represented by such Certificate, as contemplated by this Article 2.

Section 2.10 Adjustments. If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of Hurricane or Cyclone shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period, the Exchange Ratio and any amounts payable pursuant to Section 2.05(f) or Section 2.07 of this Agreement shall be appropriately adjusted.

Section 2.11 Dissenting Stockholders. Notwithstanding any provision of this Agreement to the contrary, shares of Cyclone Stock that are outstanding immediately prior to the Effective Time and that are held by a holder thereof who has not voted in favor of or consented to the adoption of this Agreement and has properly exercised and perfected appraisal rights for such shares in accordance with Section 262 of Delaware Law (the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration, but shall become the right to receive such consideration as may be determined to be due to such holder pursuant to the procedures set forth in Section 262 of Delaware Law to be paid by the Surviving Corporation; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal and payment under Delaware Law, the right of such holder to such appraisal of its shares of Cyclone Stock shall cease and such shares of Cyclone Stock shall be deemed converted as of the Effective Time into the right to receive the Merger Consideration to which any such holder is entitled pursuant to Section 2.04(a), any cash in lieu of fractional shares payable to any such holder pursuant to Section 2.07 and any dividends or other distributions to which any such holder is entitled pursuant to Section 2.05(f), in each case without interest. Cyclone shall give Hurricane (a) prompt notice of any written demands for appraisal received by Cyclone, withdrawals of such demands, and any other related instruments served pursuant to Section 262 of Delaware Law and received by Cyclone and (b) the opportunity to direct all negotiations and proceedings with respect to demands for appraisals under Delaware Law.

Section 8.05 Director and Officer Liability. Hurricane shall cause the Surviving Corporation, and the Surviving Corporation hereby agrees, to do the following:

(a) Hurricane shall cause the Surviving Corporation to assume the obligations with respect to all rights to indemnification and exculpation from liabilities, including advancement of expenses, for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors or officers of Cyclone (or its Subsidiaries) (each an “Indemnified Person”) as provided under Cyclone’s certificate of incorporation, bylaws or any indemnification Contract between such directors or officers and Cyclone (in each case, as in effect on the date hereof), without further action, as of the Effective Time and such obligations shall survive the Merger and shall continue in full force and effect in accordance with their terms.

(b) For six years after the Effective Time, Hurricane shall, or shall cause the Surviving Corporation to, provide officers’ and directors’ liability insurance in respect of acts or omissions occurring prior to the Effective Time covering each such Indemnified Person currently covered by Cyclone’s officers’ and directors’ liability insurance policy on terms with respect to coverage and amount no less favorable than those of such policy in effect on the date hereof; provided, however, that Hurricane or the Surviving Corporation, as the case may be, may (i) substitute therefor policies of Hurricane or the Surviving Corporation, as the case may be, containing terms with respect to coverage (including as coverage relates to deductibles and exclusions) and amounts no less favorable to such directors and officers or (ii) request that Cyclone obtain such extended reporting period coverage under its existing insurance programs (to be effective as of the Effective Time); provided, further, that, in satisfying its obligation under this Section 8.05(b), neither Hurricane nor the Surviving Corporation shall be obligated to pay an aggregate annual premium in excess of the amounts described on Section 8.05(b) of the Hurricane Disclosure Schedule. It is understood and agreed that in the event such coverage cannot be obtained for such amount or less in the aggregate, Hurricane or the Surviving Corporation, as the case may be, shall only be obligated to provide such coverage as may be obtained for such aggregate amount. In lieu of the foregoing, Cyclone may obtain prepaid policies prior to the Effective Time, which policies may provide the Indemnified Persons with coverage of equivalent amount and on no more favorable terms than are provided by Cyclone’s current policy in effect on the date hereof for an aggregate period of at least six years with respect to claims arising from facts or events that occurred on or before the Effective Time, including in connection with the approval of this Agreement and the transactions contemplated hereby.

Section 8.07 No Solicitation; Other Offers.

(a) General Prohibitions. Subject to the remainder of this Section 8.07, neither Cyclone nor Hurricane (either, a “No-Shop Party”) shall, and no such No-Shop Party shall authorize or permit any of its respective Subsidiaries or any of their respective officers, directors, employees, investment bankers, attorneys, accountants, consultants or other agents or advisors to, directly or indirectly, (i) solicit, initiate or take any action to knowingly facilitate or knowingly encourage the submission of any Acquisition Proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations with, furnish any information relating to that No-Shop Party or any of its Subsidiaries or afford access to the business, properties, assets, books or records of that No-Shop Party or any of its Subsidiaries to, otherwise cooperate in any way with, or knowingly assist, participate in, knowingly facilitate or knowingly encourage any effort by any Third Party that is seeking to make, or has made, an Acquisition Proposal, (iii) make an Adverse Recommendation Change, (iv) grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of that No-Shop Party or any of its Subsidiaries, (v) enter into any agreement in principle, letter of intent, term sheet or other similar instrument relating to an Acquisition Proposal (other than a confidentiality agreement of the sort and in the circumstances described in Section 8.07(b)) or (vi) propose publicly or agree to do any of the foregoing related to any Acquisition Proposal.

(b) Exception to Permit Discussions and/or Due Diligence. Notwithstanding the foregoing, the Board of Directors of a No-Shop Party, directly or indirectly through advisors, agents or other intermediaries, may, prior to Hurricane Stockholder Approval (in the case of Hurricane) or Cyclone Stockholder Approval (in the case of Cyclone), (i) engage in negotiations or discussions with any Third Party that, subject to such No-Shop Party’s compliance with Section 8.07(a), has made an unsolicited bona fide written Acquisition Proposal that such No-Shop Party’s Board of Directors has determined in good faith (after consultation with its outside legal counsel and financial advisors of nationally recognized reputation) constitutes or is reasonably likely to lead to a Superior Proposal (a “Takeover Response”) and (ii) after making such determination furnish to such Third Party non-public information relating to that No-Shop Party or any of its Subsidiaries pursuant to a confidentiality agreement with terms no less favorable to that No-Shop Party than those contained in the Confidentiality Agreement dated April 5, 2007 between Cyclone and Hurricane (the “Confidentiality Agreement”) (a copy of which shall be provided for informational purposes only to the other party), but in each case referred to in the foregoing clauses (i) and (ii) only if the Board of Directors of that No-Shop Party determines in good faith by a majority vote, after considering advice from outside legal counsel to that No-Shop Party, that failing to take that action would be inconsistent with its fiduciary duties under Applicable Law.

(c) Required Notices. The Board of Directors of a No-Shop Party shall not take any of the actions referred to in clauses (i) and (ii) of the preceding subsection unless that No-Shop Party shall have delivered to the other Party a prior written notice advising such other party that it intends to take such action. In addition, a No-Shop Party shall notify the other Party promptly (but in no event later than 24 hours) after receipt by that No-Shop Party, or any of its advisors) of any Acquisition Proposal, any indication that a Third Party is considering making an Acquisition Proposal or of any request for information relating to such No-Shop Party or any of its Subsidiaries or for access to the business, properties, assets, books or records of such No-Shop Party or any of its Subsidiaries by any Third Party that may be considering making, or has made, an Acquisition Proposal. Such No-Shop Party shall provide such notice orally and in writing and shall identify the Third Party making, and the terms and conditions of, any such Acquisition Proposal, indication or request. A No-Shop Party shall keep the other Party reasonably informed, on a current basis, of the status and details of any such Acquisition Proposal, indication or request.

(d) Ability to Change Recommendation.

(A) Notwithstanding anything in this Agreement to the contrary, a No-Shop Party and its Board of Directors shall be permitted, other than in response to an Acquisition Proposal, to effect an Adverse

A-56

##### Table of Contents

Recommendation Change if (i) such No-Shop Party shall not have received the Cyclone Stockholder Approval (in the case of Cyclone) or the Hurricane Stockholder Approval (in the case of Hurricane) and (ii) in response to a material development or change in circumstances occurring or arising after the date hereof that was not known to the Board of Directors of the No-Shop Party as of or prior to the date hereof (which change or development does not relate to an Acquisition Proposal and which change or development is not, and does not result from, a change in the market price of the common stock of the other party primarily as a result of the announcement of the transactions contemplated hereby) (such material development or change in circumstances, an “Intervening Event”), the Board of Directors of such No-Shop Party has determined in good faith (after consultation with, and taking into account the advice of, its outside legal counsel) that, in light of such Intervening Event, the failure of the Board of Directors of such No-Shop Party to effect such an Adverse Recommendation Change would result in a breach of its fiduciary duties under Applicable Law; provided that, the Board of Directors of a No-Shop Party shall nevertheless not make such an Adverse Recommendation Change pursuant to this sentence unless (x) such No-Shop Party promptly notifies the other party, in writing, at least three (3) Business Days before taking that action (unless the Intervening Event arises fewer than six (6) Business Days prior to the Hurricane Stockholders’ Meeting or Cyclone Stockholders Meeting, as the case may be) advising the other party that the Board of Directors of the No-Shop Party intends to take such action and specifying the reasons therefor in reasonable detail and (y) during such three (3) Business Day period, if requested by the other party, engaged in good faith negotiations with such party to amend this Agreement in such a manner that obviates the need for a Adverse Recommendation Change as a result of the Intervening Event.

(B) Notwithstanding anything in this Agreement to the contrary (but subject to the following sentence), in response to an Acquisition Proposal from a Third Party, a No-Shop Party and its Board of Directors shall be permitted to effect an Adverse Recommendation Change and, subject to compliance with the provisions of Section 11.04, immediately terminate this Agreement in accordance with Section 10.01 if (i) such No-Shop Party shall not have received the Cyclone Stockholder Approval (in the case of Cyclone) or the Hurricane Stockholder Approval (in the case of Hurricane), (ii) it has received an unsolicited bona fide written Acquisition Proposal from a Third Party, (iii) its Board of Directors has determined in good faith (after consultation with its outside legal counsel and financial advisors of a nationally recognized reputation and taking into account any adjustments to the terms and conditions of this Agreement proposed by the other party in response to the notice contemplated by the next sentence) that such Acquisition Proposal constitutes a Superior Proposal and (iv) its Board of Directors, after consultation with its outside legal counsel, determines in good faith that the failure to take such action would be inconsistent with its fiduciary duties under Applicable Law. However, the Board of Directors of a No-Shop Party shall nevertheless not make such an Adverse Recommendation Change or terminate this Agreement in accordance with the foregoing, unless, (x) such No-Shop Party promptly notifies the other party, in writing at least three (3) Business Days before taking that action, of its intention to make an Adverse Recommendation Change (such notice, a “Notice of Superior Proposal”) and specifying the reasons therefor, including the terms and conditions of any Superior Proposal that is the basis of the proposed action by the Board of Directors of the No-Shop Party and the identity of the person making the proposal (it being understood and agreed that any amendment to the financial terms or any material amendment to any other material term of any such Superior Proposal shall require a new Notice of Superior Proposal and a new three (3) Business Day period), (y) during such three (3) Business Day period, if requested by the other party, engaged in good faith negotiations with such party to amend this Agreement in such a manner than any Acquisition Proposal which was determined to constitute a Superior Proposal no longer is a Superior Proposal; and (z) at the end of such three (3) Business Day period, determined that such Acquisition Proposal has not been withdrawn and continues to constitute a Superior Proposal (taking into account any changes to the financial terms of this Agreement proposed by the other party following a Notice of Superior Proposal, as a result of the negotiations between the No-Shop Party and the other party pursuant to clause (y) or otherwise).

(C) Any Adverse Recommendation Change shall not change the approval of this Agreement, or any other approval of the Board of Directors of Cyclone or Hurricane, as the case may be, including in

A-57

##### Table of Contents

any respect that would have the effect of causing any state (including Delaware) corporate takeover statute or other similar statute to be applicable to the transactions contemplated hereby or thereby, including the Merger.

(e) Obligation to Terminate Existing Discussions. Each No-Shop Party shall, and shall cause its Subsidiaries and the advisors, employees and other agents of such No-Shop Party to, cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any Third Party conducted prior to the date hereof with respect to any Acquisition Proposal and shall use all commercially reasonable efforts to cause any such Third Party (or its agents or advisors) in possession of confidential information about that No-Shop Party that was furnished by or on behalf of that No-Shop Party to return or destroy all such information.

(f) Definition of Superior Proposal. For purposes of this Agreement, “Superior Proposal” means any bona fide, unsolicited written Acquisition Proposal (which definition shall be read, for this purpose, without the word “inquiry” in clause (i) and (ii) thereof) for at least a majority of the outstanding shares of Cyclone Stock or Hurricane Stock (as the case may be) or a sale or purchase of all or substantially all the assets of Cyclone or Hurricane (as the case may be) on terms that the Board of Directors of a No-Shop Party determines in good faith by a majority vote, after consultation with its legal advisor and financial advisors of nationally recognized reputation and taking into account such matters deemed relevant in good faith by such Board of Directors, including among other things, all the terms and conditions of the Acquisition Proposal, including any break-up fees, expense reimbursement provisions, conditions to consummation and long-term strategic considerations, are more favorable from a financial point of view to the stockholders of such No-Shop Party than the Merger and for which (x) financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to be available and (y) such proposed transaction is reasonably capable of being completed on the terms set forth in the Acquisition Proposal, each as determined by the Board of Directors of that No-Shop Party.

(g) Nothing contained in this Section 8.07 shall prohibit a No-Shop Party from (x) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) under the 1934 Act or making a statement required under Rule 14a-9 under the 1934 Act or (y) making any disclosure of factual matters to the stockholders of the Company if, in the good faith judgment of the Board of Directors of such No-Shop Party (after consultation with its outside legal counsel) it is required to disclose in order to not breach its fiduciary duties to such No-Shop Party’s stockholders under Applicable Law; provided, however that (i) compliance with such rules shall in no way limit or modify the effect that any such action pursuant to such rules has under this Agreement and (ii) in no event shall such No-Shop Party or its Board of Directors or any committee thereof take, or agree or resolve to take, any action prohibited by Section 8.07(a), (b), (c) or (d).

(b) Cyclone shall use commercially reasonable efforts to cause to be delivered to Hurricane two letters from Cyclone’s independent public accountants, one dated approximately the date on which the Registration Statement shall become effective and one dated a date within two Business Days of the Closing Date, each addressed to Cyclone and Hurricane, in form reasonably satisfactory to Hurricane and customary in scope for comfort letters delivered by independent public accountants in connection with registration statements similar to the Registration Statement.

Section 8.10 Access to Information. From the date hereof until the Effective Time and subject to Applicable Law and the Confidentiality Agreement, Cyclone and Hurricane shall (i) give to the other party, its counsel, financial advisors, auditors and other authorized representatives reasonable access (including for the purpose of coordinating integration planning activities and transition planning with the employees of Cyclone and its Subsidiaries) during normal business hours and upon reasonable notice to the offices, properties, books and records of such party, (ii) furnish to the other party, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (iii) instruct its employees, counsel, financial advisors, auditors and other authorized representatives to cooperate with the other party in its investigation. Any investigation pursuant to this Section shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the other party. No information or knowledge obtained in any investigation pursuant to this Section shall affect or be deemed to modify any representation or warranty made by any party hereunder. Notwithstanding the foregoing, none of the parties shall be required to provide access to or to disclose information to another party where such access or disclosure would jeopardize the attorney-client or other legal privilege of the disclosing party or contravene any Applicable Law or binding agreement entered into prior to the date of this Agreement (provided that the parties shall use commercially reasonable efforts to provide such information or access in a manner that does not cause such prohibition or violation).

Section 8.11 Notices of Certain Events. Each party shall promptly notify the others of:

(d) any inaccuracy of any representation or warranty contained in this Agreement at any time during the term hereof that would reasonably be expected to cause any condition set forth in Article 9 not to be satisfied; and

(e) any failure of that party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder that would reasonably be expected to cause any condition set forth in Article 9 not to be satisfied;

provided that the delivery of any notice pursuant to this Section 8.11 shall not limit or otherwise affect the remedies available hereunder to the party receiving that notice.

Section 8.12 Tax Treatment. Hurricane and Cyclone intend the Merger to qualify as a reorganization under Section 368(a) of the Code and the parties hereby adopt this Agreement as a plan of reorganization within the meaning of Treasury Regulation Section 1.368-2(g) and 1.368-3T(a).

Each of Hurricane, MergerSub and Cyclone and each of their respective affiliates shall use their best efforts not to take any action, or fail to take any action, or cause any action to be taken or not taken, or suffer to exist any condition, which action or failure to take action or condition would prevent, or would be reasonably likely to prevent, the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

Section 8.13 Affiliates. Cyclone shall deliver to Hurricane a letter identifying all known Persons who may be deemed affiliates of Cyclone under Rule 145 of the 1933 Act, and thereafter Cyclone shall use all commercially reasonable efforts to obtain a written agreement from each Person who may be so deemed as soon as practicable and, in any event, at least 30 days prior to the Effective Time, in a customary form to be agreed by the parties for purposes of Rule 145 of the 1933 Act (each, an “Affiliate Agreement”).

The mere inclusion of an item in either the Cyclone Disclosure Schedule or the Hurricane Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has had or would be reasonably expected to have a Material Adverse Effect on Cyclone or Hurricane, as applicable; and

(b) any information contained in any part of any Cyclone SEC Document or of any Hurricane SEC Document shall only be deemed to be an exception to (or, as applicable, a disclosure for purposes of) the representations and warranties of the relevant party if the relevance of that information as an exception to (or a disclosure for purposes of) such representations and warranties would be readily apparent on its face to a reasonable person who has read that information and such representations and warranties, without any independent knowledge on the part of the reader regarding the matter(s) so disclosed, provided that in no event shall any information contained in any part of any Cyclone SEC Document or of any Hurricane SEC Document entitled “Risk Factors” or “Forward-Looking Statements” be deemed to be an exception to (or, as applicable, a disclosure for purposes of) any representation(s) and warranty(ies) of Cyclone or Hurricane that is contained in this Agreement.

Section 11.06 Binding Effect; Benefit; Assignment.

(a) The provisions of this Agreement shall be binding upon and, except as provided in Section 8.05 and Section 8.18(g), shall inure to the benefit of the parties hereto and their respective successors and assigns.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the written consent of each other party hereto, except that any party may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to (i) one or more of their Affiliates at any time and (ii) after the Effective Time, to any Person; provided that such transfer or assignment shall not relieve such party of its obligations hereunder or enlarge, alter or change any obligation of any other party hereto or due to such party.

Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 11.13 Specific Performance.

Cytyc’s domestic diagnostic products division develops and markets the ThinPrep® System in the United States primarily for use in cytology testing applications, such as cervical cancer screening. As a result of Cytyc’s acquisition of Adeza on March 19, 2007, this segment also develops and markets FullTerm TM, The Fetal Fibronectin Test, which offers clinical and cost benefits for the assessment of the risk of pre-term birth.

The ThinPrep System. The ThinPrep System is the most widely used method for cervical cancer screening in the United States. Cervical cancer is one of the most common cancers among women throughout the world. If detected in the pre-cancerous stage, virtually all cervical cancer cases are preventable. The ThinPrep System for cervical cancer screening is a covered benefit by most health insurance plans in the United States. The ThinPrep System consists of any one or more of the following: the ThinPrep 2000 Processor, ThinPrep 3000 Processor, ThinPrep Imaging System, and related reagents, filters and other supplies, such as the ThinPrep Pap Test and Cytyc’s proprietary ThinPrep PreservCyt® Solution.

The U.S. Food and Drug Administration (“FDA”) approved the ThinPrep Pap Test in 1996 as an effective replacement for the conventional Pap smear method for the detection of low grade and more severe lesions in a variety of patient populations. The FDA later allowed expanded labeling to include Cytyc’s clinical trial data, which indicated a 59.7% increase in the detection of high grade lesions with the ThinPrep System. The ThinPrep System offers significantly improved specimen quality over that of the conventional Pap smear method. Since the FDA approval, a number of studies have been published or presented that evaluate the performance of the ThinPrep Pap Test compared to the conventional Pap smear. These studies have been conducted in every region of the United States, as well as Canada, the United Kingdom, Europe, Asia, Central America and Australia and have consistently demonstrated improved detection of pre-cancerous cervical lesions compared to the conventional Pap smear. Of particular importance is the number of studies demonstrating statistically significant increases in the detection of high-grade cervical lesions, which are the immediate precursors to cervical cancer. These studies demonstrate a wide range of benefits including increased disease detection, reduction of equivocal diagnoses and false negatives, improved specimen adequacy, adjunctive molecular testing, morphology assessment, and cost effectiveness.

The ThinPrep System also serves as a platform for additional gynecological applications using residual patient specimen collected in ThinPrep PreservCyt Solution. Cytyc’s PreservCyt Solution has been approved by the FDA as a transport medium in testing for sexually transmitted infections due to Chlamydia trachomatis and

Neisseria gonorrhea directly from the ThinPrep Pap Test vial using Roche Diagnostics Corporation’s (“Roche”) COBAS Amplicor™ automated system, as well as using Gen-Probe Incorporated’s APTIMA Combo 2® assay. In addition, Cytyc’s PreservCyt Solution has been approved by the FDA as a transport medium for testing for the human papillomavirus (“HPV”) using Digene Corporation’s (“Digene”) Hybrid Capture® II HPV DNA Assay. Cytyc has also obtained approval of two pre-market approval supplements from the FDA: (i) one that allows for the removal of up to four milliliters from the PreservCyt sample vial before preparing the ThinPrep Pap Test slide to better facilitate ancillary testing, which improves the implementation of and provides broader application of molecular testing, particularly in high-volume laboratories and (ii) one related to the detection of endocervical and endometrial glandular lesions with the ThinPrep Pap Test.

The ThinPrep Imaging System is a device that uses computer imaging technology to assist in primary cervical cancer screening of ThinPrep Pap Test slides processed through the ThinPrep System. The system combines imaging technology to identify diagnostic fields of interest with an automated microscope to facilitate locating these fields. Cytyc’s clinical data indicates an increase in sensitivity in the detection of atypical squamous cells of undetermined significance and more severe lesions when using the ThinPrep Imaging System to review a ThinPrep Pap Test slide as compared to manual review. Additionally, cytotechnologists using the ThinPrep Imaging System are subject to higher workload limits compared to the workload limits applicable to manual review of slides. As a result, Cytyc believes the ThinPrep Imaging System increases, and is expected to continue to increase, a cytology laboratory’s screening productivity and diagnostic accuracy while leveraging the increased effectiveness of the ThinPrep Pap Test. Approximately 38% of all ThinPrep Pap Test slides were screened using the ThinPrep Imaging System by the end of 2006.

The ThinPrep Process. The ThinPrep process begins with the patient’s cervical sample being taken by the physician using a cervical sampling device that, rather than being smeared on a microscope slide as in a conventional Pap smear, is rinsed in a vial filled with Cytyc’s proprietary PreservCyt Solution. This enables virtually all of the patient’s cell sample to be preserved before the cells can be damaged by air drying. The ThinPrep specimen vial is then labeled and sent to a laboratory equipped with a ThinPrep Processor for slide preparation.

At the laboratory, the ThinPrep specimen vial is inserted into a ThinPrep Processor, a proprietary sample preparation device which automates the process of preparing cervical specimens. Once the vial is inserted into the ThinPrep Processor, a dispersion step breaks up blood, mucus, non-diagnostic debris and large sheets of cells and homogenizes the cell population. The cells are then automatically collected onto Cytyc’s proprietary ThinPrep Pap Test Filter, which incorporates a porous membrane specifically designed to collect cells. The ThinPrep Processor constantly monitors the rate of flow through the ThinPrep Pap Test filter during the cell collection process in order to prevent the cellular concentration from being too scant or too dense. A thin layer of cells is then transferred from the filter to a glass slide in a 20 mm-diameter circle and the slide is automatically deposited into a fixative solution. This slide is then available for microscopic examination.

The cytotechnologist manually screens each Pap test slide with a microscope to first determine the adequacy of the slide and to then differentiate diseased or abnormal cells from healthy cells. With the ThinPrep Imaging System, the screening process has been automated to combine the power of computer imaging technology and human interpretive skills. Prior to human review, the ThinPrep Imaging System rapidly scans and locates areas of interest for review. The cytotechnologist then places the imaged slide onto the ThinPrep Imaging System review scope which automatically presents each area of interest to the cytotechnologist in geographic order. The cytotechnologist evaluates each area of interest, selecting those areas which require further pathologist review, or the cytotechnologist may look beyond the identified areas of interest. Alternatively, the cytotechnologist can determine that the slide is negative and simply sign the case out. By directing the cytotechnologist to areas of interest on a slide, the system may increase a cytology laboratory’s screening productivity and diagnostic accuracy.

Additional Applications of the ThinPrep System. In addition to acting as a replacement for the conventional Pap smear, the ThinPrep System also offers significant improvements for non-gynecological cytology screening

B-2

##### Table of Contents

applications. Non-gynecological cytology applications include fine-needle aspiration specimens (e.g., breast, thyroid, lung or liver), lavage specimens (e.g., breast, gastrointestinal), body fluids (e.g., urine, pleural fluid, ascitic fluid, pericardial fluid), respiratory specimens (e.g., sputum, brushing of respiratory tracts) and ancillary testing (e.g., cell blocks, immunocytochemistry, special stains). The ThinPrep System provides significant improvements over other methods of non-gynecological cytology screening by optimizing cell preservation through use of Cytyc’s CytoLyt® and PreservCyt Solutions, standardizing preparation of specimens using the gentle dispersion and transfer process of the ThinPrep 2000 Processor, simplifying slide screening by offering one single, well-preserved slide per case and allowing laboratories to perform additional ancillary testing out of one PreservCyt Solution vial.

FullTerm, The Fetal Fibronectin Test and Gestiva. In connection with Cytyc’s acquisition of Adeza Biomedical Corporation, Cytyc acquired a patented diagnostic test, the Fetal Fibronectin Test, that utilizes a single-use, disposable cassette and is analyzed on Adeza’s patented instrument, the TLiIQ® System. This test is approved by the Food and Drug Administration, or FDA, for broad use in assessing the risk of preterm birth and is branded as FullTerm™, The Fetal Fibronectin Test. FullTerm is designed to objectively determine a woman’s risk of preterm birth by detecting the presence of a specific protein, fetal fibronectin, in vaginal secretions during pregnancy. Adeza began selling its single-use, disposable FullTerm in 1999 and launched its second-generation system, the TLiIQ System, in 2001. Sales of TLiIQ Systems to hospital and clinical laboratories allow healthcare providers access to Adeza’s FullTerm, resulting in the potential for better patient care and for significant cost savings by avoiding unnecessary medical treatment. Cytyc has also acquired Gestiva™ (17 alpha-hydroxyprogesterone caproate injection 250 mg/ml), a pharmaceutical product candidate to prevent preterm birth in women at risk of preterm delivery. A New Drug Application, or NDA, has been submitted with the FDA for Gestiva. On January 31, 2007, Adeza announced that the Office of Orphan Products Development of the FDA has granted Orphan Drug designation covering Gestiva. If Gestiva is approved, Orphan Drug designation provides the opportunity for seven years of U.S. market exclusivity.

Customers and Competition of the Domestic Diagnostic Products Division.

Customers. Within the domestic diagnostic products division, no customer accounted for more than 10% of Cytyc’s consolidated net sales for the year ended December 31, 2006 or the quarter ended March 31, 2007. One customer, Quest Diagnostics, Incorporated, accounted for 11% and 17% of Cytyc’s consolidated net sales for the years ended December 31, 2005 and 2004, respectively. These year-over-year decreases are primarily due to increased unit sales to new and existing customers, therefore resulting in net sales to Quest representing a smaller percentage of total consolidated net sales.

Competition. While Cytyc is the market leader in the sale of liquid-based slide preparation systems in the United States, it faces direct competition in the United States from Becton, Dickinson and Company (“Becton Dickinson”), who acquired TriPath Imaging, Inc. in the fourth quarter of 2006 and who also manufactures liquid-based slide preparation systems and slide imaging systems, and from other sample preparation systems on a worldwide basis. In addition, Cytyc competes with MonoGen, Inc. who uses a liquid-based slide preparation system. Cytyc also competes with the conventional Pap smear and other alternative methods for detecting cervical cancer and/or its precursors, such as that manufactured by Digene. Cytyc competes on the basis of a number of factors, including clinical performance, product quality, marketing and sales capabilities, manufacturing efficiency, price and customer service and support. The development, FDA approval and commercial marketing of competing systems for cervical cancer screening could have a material adverse effect on Cytyc’s business, financial condition and results of operations.

Cytyc is currently the only provider of FullTerm, a fetal fibronectin test for predicting the risk of preterm birth. However, it could experience competition for the preterm birth diagnostic products from companies that manufacture and market pregnancy-related diagnostic products and services. These companies may be significantly larger and have access to substantially more capital for new product development and sales and

B-3

##### Table of Contents

marketing. These companies may develop new diagnostic products or technologies that could compete with or entirely displace Cytyc’s products and technologies. For example, other biomarkers, including cytokines and other proteins indicative of infection, and proteomics are the subject of research that may yield new products or technologies.

In addition, healthcare providers use diagnostic techniques such as clinical examination and ultrasound to diagnose the likelihood of preterm birth. Healthcare providers may choose to continue using these techniques to assess their patients, rather than use FullTerm. They may also choose to use these techniques in conjunction with FullTerm to predict preterm birth.

Domestic Surgical Products

Cytyc’s domestic surgical products division develops and manufactures the NovaSure® System, the MammoSite® Radiation Therapy System and the GliaSite® Radiation Therapy System and markets these products in the United States. As a result of Cytyc’s acquisition of Adiana Inc., this segment also develops the Adiana Complete Transcervical Sterilization System® (“TCS”), which is a form of permanent female contraception intended as an alternative to tubal ligation and for which Cytyc is in the process of seeking a pre-market approval (“PMA”) from the FDA.

The NovaSure System. The NovaSure System allows physicians to treat women suffering from excessive menstrual bleeding in a minimally invasive manner to eliminate or reduce their bleeding. The FDA granted pre-market approval in September 2001 for the NovaSure System to treat excessive menstrual bleeding due to benign causes in women for whom childbearing is complete. The NovaSure System was commercially launched in the United States in early 2002.

Cytyc estimates that there are approximately seven million women in the United States that suffer from excessive menstrual bleeding who are generally considered beyond typical childbearing age and of these, approximately 2.5 million seek treatment. Industry sources estimate that one in five women worldwide is affected by excessive menstrual bleeding. Excessive menstrual bleeding can have a significant impact on a woman’s quality of life by disrupting family, social, personal and professional activities. Gynecologists typically diagnose excessive menstrual bleeding, determine the best treatment and prescribe or perform the therapy. Successful treatment of excessive menstrual bleeding is typically defined as a reduction of menstrual blood loss to a normal level, a state known as eumenorrhea. Treatment may also result in the complete cessation of menstrual bleeding, a state known as amenorrhea. Often treatment of excessive menstrual bleeding begins with drug therapy, which preserves a woman’s ability to bear children but may have significant side effects and/or contra-indications. Women who do not desire to have children may pursue alternative solutions including traditional surgeries, such as hysterectomy, dilation and curettage or rollerball ablation, or second generation minimally invasive endometrial ablation procedures like the NovaSure System.

The NovaSure System provides physicians and patients with a fast, simple, safe and effective treatment for excessive menstrual bleeding. The system consists of a disposable device and a controller that delivers radio frequency, or RF, energy to the endometrial wall of the uterus to ablate the endometrium. The NovaSure disposable device is a hand-held, single-use device that incorporates a flexible gold-plated mesh electrode used to deliver radiofrequency energy during the NovaSure procedure. The NovaSure RF Controller generates and delivers an amount of radiofrequency energy individually determined for each patient, monitors several critical treatment and safety parameters, and automatically controls other aspects of the procedure.

The NovaSure procedure is typically performed as an outpatient procedure in the hospital, ambulatory surgery center or physician’s office. Cytyc believes the NovaSure System offers significant benefits to physicians, patients, hospitals and outpatient surgery centers, including clinical efficacy, fast and efficient treatment, lack of a need for pre-treatment, minimal anesthesia requirements, convenience, ease of use, a variety of safety features and nationally available reimbursement. Based on pivotal clinical trial data used to obtain

B-4

##### Table of Contents

initial U.S. regulatory approval, the NovaSure System was demonstrated to have a success rate for treatment of 77.7% at twelve months after treatment, as compared to a success rate of 74.4% by rollerball ablation, a traditional “first generation” endometrial ablation treatment.

The NovaSure System is the only commercially available “second generation” endometrial ablation therapy approved by the FDA to be performed without drug or surgical pre-treatment. Pre-treatment can be time-consuming, expensive and inconvenient for both patients and physicians and can result in uncomfortable or painful side effects and complications. The NovaSure procedure is completed in a single outpatient visit. In addition, in Cytyc’s pivotal clinical trial, the mean procedure time, or the period from device insertion to device removal, for the NovaSure System was 4.2 minutes, as compared to 24.2 minutes for rollerball ablation. The NovaSure System has the shortest treatment time (average of 84 seconds of RF energy delivery), based on labeling indications for other FDA-approved second generation endometrial ablation therapies. In addition, patients have a median recovery room time of 85 minutes and most NovaSure patients return to normal activities within one to two days. In Cytyc’s pivotal clinical trial, general anesthesia was used in 27% of NovaSure cases as compared to 82% of cases using rollerball ablation. Therefore, Cytyc believes NovaSure is less expensive, avoids the risks associated with general anesthesia and permits faster patient recovery as compared to rollerball ablation. Also, in Cytyc’s experience, physicians and nursing personnel quickly understand how to use the NovaSure System effectively after proper training.

The MammoSite System. The MammoSite Radiation Therapy System is a single-use device for the treatment of early-stage breast cancer, which incorporates a patented balloon catheter that positions a therapeutic radiation source directly into the surgical cavity created after removal of a tumor from the breast. Industry sources estimate that one in eight women in the United States will eventually be diagnosed with breast cancer, which accounts for approximately one-third of all female cancers and is the second overall leading cause of cancer death. On a worldwide basis, over 1.2 million women are diagnosed with breast cancer annually. The MammoSite System positions a radiation source directly within the post-surgical cavity, delivering optimally dosed radiation to the tissue that is at the highest risk for cancer recurrence while minimizing radiation exposure to adjacent healthy tissue. Most importantly, the device allows for radiation treatment to be completed within five days as compared to six to seven weeks for traditional radiation therapy. Cytyc believes the MammoSite System also offers patients better cosmetic outcomes resulting in high patient satisfaction.

Over the past few decades, breast cancer diagnosis and treatment has been evolving from the radical mastectomy alone to lumpectomy, which is a less disfiguring, breast-conserving surgical therapy for early-stage cancer patients followed by a course of radiation. The MammoSite System provides partial-breast irradiation, which delivers high-dose radiation to the specific lumpectomy site for five days while minimizing radiation exposure to adjacent healthy tissue. The MammoSite System is an alternative to traditional radiation therapy during which the patient is exposed to external beam radiation for a period of six to seven weeks resulting in radiation exposure to healthy tissue in addition to the cancer site. Published data indicates that on an annual basis, approximately 25% of breast cancer patients who undergo lumpectomy surgery choose not to receive any form of post-surgical radiation as a result of the harmful effects of traditional radiation therapy and the hardship of an extended schedule of daily therapy.

There are few FDA restrictions on the use of the MammoSite System for patients undergoing lumpectomy; however, indications have shown that patients with tumors with a diameter of less than three centimeters and those at least 45 years of age are the most appropriate for the MammoSite procedure. The MammoSite System is comprised of an inflatable balloon catheter in which a radioactive source is introduced for therapy delivery. The inflatable balloon is inserted into the surgical cavity remaining after removal of the tumor. The catheter portion of the system allows the radioactive source to be added or withdrawn over the course of the therapy. This local placement of the balloon enhances therapeutic delivery of radiation to the tissue most likely to contain residual cancerous cells following surgery.

The GliaSite System. Each year, over 18,500 people in the United States are diagnosed with primary malignant brain tumors. Brain metastases occur approximately ten times more often than primary tumors and

B-5

##### Table of Contents

occur in approximately 20% to 40% of all cancer patients, most commonly in patients with primary lung or breast cancer. Malignant brain tumors recur frequently, often within one year and typically near the original tumor site. Industry sources estimate that most patients die within one year of diagnosis and within six months of recurrence.

The GliaSite System works in the same manner and utilizes similar technology as the MammoSite System. The GliaSite System provides a full course of post-surgical radiation therapy using Iotrex, a proprietary, liquid radiation source for which Cytyc has an exclusive license. In clinical trials, the GliaSite System has demonstrated equivalent, median survival time, preservation of cognitive function and quality of life compared to external beam whole brain irradiation. The GliaSite System allows for radiation treatment to be completed within three to six days and often as an outpatient therapy.

The Adiana Complete Transcervical Sterilization System. In connection with Cytyc’s acquisition of Adiana Inc., Cytyc acquired the TCS, which is a form of permanent female contraception intended as an alternative to tubal ligation and for which Cytyc is in the process of seeking a PMA from the FDA.

Customers and Competition of the Domestic Surgical Products Division Customers.

Customers. No customer within the domestic surgical products division accounted for more than 10% of Cytyc’s consolidated net sales for the years ended December 31, 2006, 2005 or 2004 or for the quarter ended March 31, 2007.

Competition. Cytyc’s NovaSure System currently faces direct competition from Johnson & Johnson, Boston Scientific Corporation, American Medical Systems, Inc. and Microsulis Medical Limited, each of which currently markets an FDA-approved “second generation” endometrial ablation device for the treatment of excessive menstrual bleeding. In addition to these devices, there exist alternative treatments to Cytyc’s NovaSure System, such as drug therapy, hysterectomy, dilation and curettage and rollerball ablation. Rollerball ablation and the Johnson & Johnson endometrial ablation device have been in use for a longer time than Cytyc’s procedure for the treatment of excessive menstrual bleeding. Because drug therapy is an alternative to Cytyc’s NovaSure procedure, Cytyc’s competitors also include many major pharmaceutical companies that manufacture hormonal drugs for women.

As a result of the relatively short period of time the MammoSite and GliaSite Systems have been in the market, these products face competition from the more commonly-known alternatives, such as treatment using external beam radiation, which has longer-term data on patient outcome, and products such as Xoft Microtube, Inc.’s (“Xoft”) electronic brachytherapy.

Current or future competitors may develop technologies and products that demonstrate better safety or effectiveness, clinical results, ease of use or lower cost than Cytyc’s surgical products. Cytyc’s surgical products may be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one or more of its competitors. Cytyc believes the principal competitive factors in its market include: product safety and proven efficacy; reliability and ease of use; customer focus and service; effective training, marketing and distribution; patent protection; and reimbursement.

International

Cytyc’s international division markets its diagnostic and surgical products outside of the United States, with a presence in Canada, Europe, Australia and Hong Kong, all of which Cytyc believes represent significant market opportunities for all of its products. These operations have been established to manage sales, service, training and distribution in the Canadian, European and Asia/Pacific markets. Cytyc also utilizes a network of third-party distributors in various other countries throughout the world, including Japan and China. Cytyc’s international strategy is to establish sales channels appropriate for increasing its international customer base, taking into consideration factors such as government regulations and clinical practices of the particular country or region.

Cytyc continues to work with the healthcare system in the United Kingdom to convert to liquid-based cytology. The local United Kingdom governments are required by law to convert to liquid-based cytology by 2008. Cytyc has agreements in place that account for approximately 3.2 million of the estimated 4.5 million tests that are performed annually in the United Kingdom. As of March 31, 2007, Cytyc estimates that approximately 43% of the United Kingdom pap tests have been converted to the ThinPrep Pap Test.

In July 2005, Cytyc entered into an exclusive agreement with Olympus Corporation, Japan’s microscope market leader, appointing Olympus as the sole and exclusive distributor for the sale of Cytyc’s ThinPrep System in Japan. Cytyc officially launched the ThinPrep System in Japan with Olympus in June 2006 and subsequently has worked with Olympus to establish the ThinPrep System with key opinion leaders in the pathology and OB/Gyn community and at leading institutions across the country. Currently, there are approximately 10 million Pap tests performed annually in Japan.

During 2006, Cytyc placed its first ThinPrep Imaging Systems in Belgium, France, Italy, Spain and South Africa.

To support its introduction of Novasure in the international markets, Cytyc has expanded its sales team in several key areas and has experienced increased sales growth of its NovaSure product in the United Kingdom, as well as in other parts of Europe. In May 2006, the Australian government included Novasure in its list of technologies that can be reimbursed in the private insurance system. Since then, Cytyc has experienced increased physician adoption of Novasure within this market. In addition, Cytyc continues to experience increased NovaSure sales growth in Canada.

For MammoSite, Cytyc is actively working with key opinion leaders in Europe to introduce the MammoSite System into the European marketplace and Cytyc is working toward building its sales force where significant market opportunities exist. In 2006, several clinical studies of MammoSite were launched in the United Kingdom, Italy and Ireland. The goal of these studies is to demonstrate the value of MammoSite as a viable alternative to whole-breast radiation therapy and will add to the body of international clinical work already completed on MammoSite in France, Italy and other European countries.

Cytyc believes that international sales and marketing efforts will continue to involve a lengthy process, requiring Cytyc to educate healthcare providers, clinical laboratories, government entities and other third-party payors regarding the clinical benefits and cost-effectiveness of Cytyc’s current products, as well as any other new products and applications. In order to effectively market its current products and any other new products and applications on a worldwide basis, Cytyc will need to continue to increase its international marketing, sales, and service capabilities.

Customers and Competition of the International Division.

Customers. No customer within the international division accounted for more than 10% of Cytyc’s consolidated net sales for the years ended December 31, 2006, 2005 or 2004 or for the quarter ended March 31, 2007.

Competition. Similar to the diagnostic products marketplace in the United States, in Europe Cytyc competes with the conventional Pap smear and other alternative methods for detecting cervical cancer and/or its precursors. In addition to Becton Dickinson, who acquired TriPath Imaging, Inc. in 2006, Cytyc competes with a variety of other companies and “off-market” (non-FDA-approved) tests, since fewer regulatory barriers exist in Europe as compared to the United States. In the endometrial ablation market, Cytyc competes with drug therapy, as well as the other endometrial ablation devices, including Johnson & Johnson’s Thermachoice, Boston Scientific Corporation’s HTA, the Microsulis Endometrial Ablation device and two other relatively small companies that market products that are not FDA approved. Cytyc’s MammoSite product faces competition from traditional mastectomy, whole breast radiation therapy after lumpectomy, and a more radical breast-conserving procedure

B-7

##### Table of Contents

called a quadrantectomy. Additional radiation therapy methods, such as intraoperative radiation therapy, are being explored in Europe by potential competitors; however, such alternative methods have not achieved widespread commercial use. In the Asia/Pacific region, the competition in the diagnostic business is composed of the conventional Pap smear, as well as many non-FDA-approved Pap tests, and in the surgical business, the competition is similar to that in Europe.

Third-Party Reimbursement

Laboratory customers bill most insurers (including Medicare) for the ThinPrep Pap Test using a Current Procedural Terminology (“CPT”) code specifically for liquid-based cervical cell specimen preparation. As of March 31, 2007, based on information provided to Cytyc, Cytyc believes that the ThinPrep Pap Test and the ThinPrep Imaging System is covered by Medicare and almost all third-party payors, thus allowing access for almost all women in the United States. Third-party reimbursement for Cytyc’s NovaSure System is well established in the United States. Cytyc’s NovaSure System is typically reimbursed by third-party payors and Medicare, with a majority of these third-party payors using Medicare reimbursement amounts, which are revised annually, as a benchmark in setting their reimbursement policies and rates, while other third-party payors do not follow the Medicare rates and may reimburse for only a portion of Cytyc’s procedure or not at all. Medicare also sets reimbursement rates annually for endometrial ablations performed in a physician’s office and those payment rates include the fees to the physician for performing the service, practice expense costs and professional liability insurance costs. The MammoSite System is generally used in hospital outpatient departments. Medicare’s reimbursement system for hospital outpatient services, groups procedures into payment categories based on clinical and cost similarity and assigns a single payment amount to each group. A number of services associated with use of the MammoSite System, including implantation of the catheters, are separately reimbursed under this system with Medicare reimbursement amounts, which are revised annually, often used as a benchmark. Payments by non-Medicare third-party payors can vary substantially depending on the reimbursement arrangements between the third-party payor and the physician or hospital.

Research and Development

Cytyc’s core research and development strategy is to enhance its existing product lines, such as the ThinPrep Imaging System, the NovaSure System, the MammoSite Radiation Therapy System and the GliaSite Radiation Therapy System through operational enhancements and cost reductions, as well as to continue to develop additional innovative medical diagnostic and surgical devices and therapeutic applications for women’s health. To implement this strategy, Cytyc is utilizing internal resources, sponsored and collaborative research agreements with leading medical institutions and acquisitions of intellectual property.

There can be no assurance that Cytyc will be successful in developing or marketing additional applications of the ThinPrep System, the NovaSure System, the MammoSite Radiation Therapy System or the GliaSite Radiation Therapy System or that Cytyc will further enhance the ThinPrep Imaging System. Furthermore, additional applications may require additional approvals from the FDA prior to the marketing of such applications. There can be no assurance that the FDA would approve such submissions on a timely basis, if at all.

Cytyc’s research and development expenses totaled $9.7 million for the quarter ended March 31, 2007 and $44.1 million, $32.3 million and $20.8 million for the years ended December 31, 2006, 2005 and 2004, respectively.

Business Development

Cytyc is continually evaluating a variety of new business opportunities that would take advantage of its distribution channels, customer call points, and existing technology. Cytyc also evaluates opportunities that could provide new customer types, distribution channels and technology capabilities. Cytyc has been making investments in early-stage companies and expects to continue to make these investments in the future (See Note

B-8

##### Table of Contents

2(j) “Other Assets” in the notes to Cytyc’s audited consolidated financial statements included in this joint proxy statement/prospectus). Cytyc believes there are new developments in diagnostic tests and therapeutics both within and outside of the women’s health sector that could represent promising growth opportunities which Cytyc might pursue through an array of potential transactions, including acquisitions, partnerships, collaborations, early-stage venture investing and direct funding of research projects, to provide access to new technologies and/or enhance product offerings. Cytyc expects that business development will continue to play an important role in the development and execution of its growth strategy.

Sales and Marketing

Cytyc’s sales and marketing objective is to achieve broad market acceptance of the ThinPrep System, including: the ThinPrep Imaging System, for cervical cancer screening and other diagnostic applications; the NovaSure System for treating excessive menstrual bleeding; the MammoSite and GliaSite Systems for the treatment of breast and malignant brain tumors; and the Fetal Fibronectin Test for assessing the risk of preterm birth. A critical element of Cytyc’s strategy in the United States is to utilize the results of its clinical trials and expanded FDA labeling to demonstrate the safety, efficacy and productivity improvements to patients, healthcare providers, clinical laboratories and third-party payors.

Cytyc plans to continue to expand its market reach through the efforts of its more than 400-person worldwide direct sales force focused on healthcare providers, clinical laboratories and third-party payors. Cytyc’s integrated sales force has been trained to cross-sell Cytyc’s product offerings, as appropriate. Cytyc is focusing significant sales and marketing efforts towards continued market adoption of the ThinPrep Imaging System, the NovaSure System, the MammoSite System, the GliaSite System and the Fetal Fibronectin Test. Cytyc expects to use its existing relationships with customers, healthcare providers and third-party payors to successfully market all of its products. Cytyc’s sales and marketing programs also focus on educating healthcare providers regarding the use of Cytyc’s products and on providing materials to help them educate their patients about Cytyc’s procedure. Cytyc’s international sales and marketing efforts involve educating healthcare providers, clinical laboratories, government entities and other third-party payors regarding the clinical benefits and cost-effectiveness of Cytyc’s current products, as well as any other new products and applications. Cytyc will continue to increase its international marketing and sales capabilities in order to effectively market Cytyc’s current and any other new products and applications.

Raw Materials and Manufacturing

Cytyc purchases many of the components and raw materials used in its products from numerous suppliers worldwide. In some cases, Cytyc has established long-term supply contracts with its suppliers. For reasons of quality assurance, sole source availability or cost effectiveness, certain components and raw materials are available only from a sole supplier. Cytyc works closely with its suppliers and develops contingency plans to assure continuity of supply while maintaining high quality and reliability. Due to the FDA’s requirements regarding manufacture of Cytyc’s products, Cytyc may not be able to quickly establish additional or replacement sources for certain components or materials. Generally, Cytyc has been able to obtain adequate supplies of such raw materials and components. In the event that Cytyc is unable to obtain sufficient quantities of raw materials or components on commercially reasonable terms or in a timely manner, Cytyc would not be able to manufacture its products on a timely and cost-competitive basis, which may have a material adverse effect on Cytyc’s business, financial condition and results of operations.

Cytyc assembles all ThinPrep Processors and ThinPrep Imaging Systems at its facility in Marlborough, Massachusetts. Cytyc fills all of the ThinPrep System vials at its facility in Londonderry, New Hampshire. Cytyc manufactures its ThinPrep System filters at both its Marlborough and Londonderry facilities. Cytyc manufactures the majority of the NovaSure disposable devices at its manufacturing facility in San Jose, Costa Rica and manufactures the remainder at its manufacturing facility in Mountain View, California. Additionally, Cytyc contracts with a leading global electronics contract manufacturer for production of the RF Controller component

Cytyc contracts with several third-parties to manufacture portions of Cytyc’s MammoSite System and GliaSite System based on Cytyc’s specifications. Cytyc takes delivery of the finished MammoSite System and certain supplies for Cytyc’s GliaSite System at its Mountain View, California facility.

Quality Systems Management

Cytyc places significant emphasis on providing quality products and services to its customers. A major portion of Cytyc’s quality systems relate to the design and development, manufacturing, packaging, sterilization, handling, distribution and labeling of Cytyc’s products. These quality systems, including control procedures that are developed and implemented by technically trained professionals, result in rigid specifications for product design, raw materials, components, packaging materials, labels, sterilization procedures and overall manufacturing process control. Cytyc’s quality systems integrate the efforts of suppliers of raw materials, components and finished goods to ensure Cytyc meets customer and regulatory requirements. These systems are designed to ensure that appropriate standards and requirements are met before goods are released for distribution. Cytyc’s quality systems are also designed to ensure that appropriate standards and requirements are met in the post-production support of its products, including warehousing, servicing and monitoring.

Certain of Cytyc’s facilities are certified under ISO 13485:2003, an international quality standard. There can be no assurance that Cytyc will be able to maintain compliance with ISO requirements or that failure to maintain compliance with these requirements will not have a material adverse effect upon Cytyc’s business, financial condition and results of operations.

Government Regulation

The manufacture, sale, lease and service of medical diagnostic and surgical devices intended for commercial use are subject to extensive governmental regulation in the United States and in other countries. Cytyc’s existing products are regulated in the United States as medical devices by the FDA under the Federal Food, Drug, and Cosmetic Act (“FDC Act”). The ThinPrep System, ThinPrep Imaging System, FullTerm, The Fetal Fibronectin Test and NovaSure System required separate pre-market application (“PMA”) approval prior to commercial distribution, which demonstrated to the FDA that these devices are safe and effective for their intended uses. The devices which comprise the MammoSite System and the GliaSite System required the clearance of 510(k) submissions prior to commercial distribution, based upon a finding that the devices are substantially equivalent to legally marketed devices that are not subject to PMA approval. Pursuant to the FDC Act, the FDA regulates the research, testing, manufacture, safety, labeling, storage, record keeping, advertising, distribution, production and servicing of medical devices in the United States. Non-compliance with applicable requirements of the FDC Act can result in the failure of the government to allow 510(k) clearance or PMA approval for a device, withdrawal of clearances or approvals, total or partial suspension of production, fines, injunctions, civil penalties, recall or seizure of products, and criminal prosecution.

The FDA’s regulations may require agency approval of a PMA supplement or clearance of a new 510(k) notification for certain changes if they affect the safety, effectiveness or substantial equivalence of the device, respectively, as a result of: new indications for use; labeling changes; the use of a different facility or establishment to manufacture, process, or package the device; changes in manufacturing facilities, methods, or quality control systems; and changes in performance or design specifications.

The FDA regulatory process can be expensive, lengthy and uncertain for both original and supplemental clearance or approvals. There can be no assurance that Cytyc will be able to obtain necessary regulatory clearances or approvals for any proposed future products or modifications of existing products. The failure to obtain clearances or approvals, loss of previously received approvals, or failure to comply with existing or future regulatory requirements, would have a material adverse effect on Cytyc’s business, financial condition and results of operations.

Beginning in 1996, FDA and/or PMA approvals were obtained for the following:

| • |  | the ThinPrep System for cervical cancer screening;

| • |  | the expanded product labeling for the ThinPrep System to include the claim that the ThinPrep System is significantly more effective in detecting Low-Grade Squamous Intraepithelial Lesions and more severe lesions than the conventional Pap smear method in a variety of patient populations;

| • |  | Cytyc’s PMA supplement application for use of a combination of an endocervical brush and spatula sampling devices;

| • |  | Cytyc’s PMA supplement applications for the testing for HPV directly from a single vial of patient specimen collected in ThinPrep solution using Digene’s Hybrid Capture and Hybrid Capture II HPV DNA Assay, respectively;

| • |  | the ThinPrep 3000 Processor, Cytyc’s batch processor for automated sample preparation;

| • |  | Cytyc’s PMA supplement application for the inclusion of data describing the improved detection of High-Grade Squamous Intraepithelial Lesions with the ThinPrep Pap Test;

| • |  | Cytyc’s PMA supplement applications to allow for testing for Chlamydia trachomatis and Neisseria gonorrhea directly from the ThinPrep Pap Test vial using Roche’s COBAS Amplicor automated system, as well as Gen-Probe Incorporated’s APTIMA Combo 2 Assay;

| • |  | Cytyc’s PMA application for the ThinPrep Imaging System;

| • |  | Cytyc’s PMA supplement that allows for the removal of up to four milliliters from the PreservCyt sample vial before preparing the ThinPrep Pap Test slide to better facilitate ancillary testing, which improves the implementation of and provides broader application of molecular testing, particularly in high-volume laboratories;

| • |  | Cytyc’s PMA application related to the detection of endocervical and endometrial glandular lesions with the ThinPrep Pap Test; and

| • |  | reprocessing specimens.

Cytyc anticipates that any other proposed uses for the ThinPrep System and ThinPrep Imaging System that impact safety or effectiveness would likely require approval of a PMA supplement or a new PMA application.

The PMA application for the NovaSure System, which Cytyc acquired in March 2004, was approved by the FDA in September 2001, authorizing commercialization of the NovaSure System for the treatment of excessive menstrual bleeding due to benign causes in pre-menopausal women who have completed childbearing. The PMA for FullTerm was approved on September 21, 2005 to detect fetal fibronectin in cervicovaginal secretions to be used as an aid to rapidly assess the risk of preterm delivery. The MammoSite System, which Cytyc acquired in March 2005, was cleared by the FDA in May 2002 for the delivery of intra-cavity radiation to the surgical margins following lumpectomy for breast cancer. Subsequent FDA clearances were received in May 2003, February 2004 and August 2004 relating to additional types of MammoSite catheters. The GliaSite System, which Cytyc also acquired in March 2005, received 510(k) clearance in April 2001, authorizing commercialization of the GliaSite System for radiation therapy in patients with any malignant brain tumor following resection surgery.

The ThinPrep, ThinPrep Imaging, FullTerm, NovaSure, MammoSite and GliaSite Systems are, and any other products Cytyc may manufacture or distribute pursuant to an approved PMA application or supplements or 510(k) clearance will be, subject to pervasive and continuing regulation by the FDA, including the Quality System Regulation, or QSR, which requires manufacturers to follow design, testing, control, documentation and other quality assurance procedures; labeling requirements; the FDA’s general prohibition against false or misleading statements in labeling or advertising products for unapproved or “off-label” uses; the Corrections and Removals regulation, which requires that manufacturers report to the FDA recalls and field corrective actions

taken to reduce a risk to health or to remedy a violation of the FDC Act that may pose a risk to health; and the Medical Device Reporting regulation, which requires that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur. Cytyc is subject to inspection by the FDA to determine its compliance with regulatory requirements. Product labeling, advertising and promotional activities may be subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. Products may only be promoted by Cytyc and any of its distributors for their approved indications. No assurance can be given that modifications to the labeling that may be required by the FDA in the future will not adversely affect Cytyc’s ability to market or sell the ThinPrep, ThinPrep Imaging, FullTerm, NovaSure, MammoSite and GliaSite Systems, or any other products Cytyc has developed, may develop or acquire. Cytyc’s failure to comply with applicable regulatory requirements could result in possible legal actions by the FDA and other regulatory agencies. Such actions may include fines, product recalls, product seizures, injunctions to halt manufacture and distribution, and other civil and criminal sanctions.

Cytyc is also subject to various federal and state laws pertaining to healthcare fraud and abuse, including federal and state anti-kickback laws, as well as the Foreign Corrupt Practices Act. Anti-kickback laws make it illegal for an entity to solicit, offer, receive, or pay remuneration or anything of value in exchange for, or to induce, the referral of business or the purchasing, leasing, ordering, or arranging for or recommending the purchase, lease or order of any item or service paid for by Medicare, Medicaid or certain other federal healthcare programs. The statute has been broadly interpreted to cover a wide array of practices. Some states have passed similar laws. The federal government has published regulations that identify “safe harbors,” which if applicable will assure that certain arrangements will not be found to violate the federal anti-kickback statutes. Cytyc’s activities relating to the sale and marketing of its products may be subject to scrutiny under these laws. While Cytyc makes every effort to comply with the regulations, it is possible that Cytyc’s practices might be challenged under federal anti-kickback or similar laws due to the breadth of the statutory provisions and the absence of extensive guidance regarding compliance. Violations of these laws may be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as the possibility of exclusion from federal healthcare programs (including Medicare and Medicaid). If the government were to raise questions about Cytyc’s behavior or find that Cytyc has violated these laws, there could be a material adverse effect on Cytyc’s business. Cytyc’s activities could be subject to challenge for the reasons discussed above, due to the broad scope of these laws and the increasing attention being given to them by law enforcement authorities.

Cytyc also is subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. There can be no assurance that Cytyc will not be required to incur significant costs to comply with such laws and regulations in the future, or that such laws or regulations will not have a material adverse effect upon Cytyc’s business, financial condition and results of operations.

Sales of medical devices outside of the United States are subject to foreign regulatory requirements that vary widely from country to country. Cytyc meets the essential requirements of the European In Vitro Medical Devices Directive that apply to the ThinPrep Pap Test, ThinPrep Imaging System and FullTerm, as well as the essential requirements of the European Medical Devices Directive that apply to the NovaSure, MammoSite and GliaSite Systems. As a result, Cytyc’s products bear the CE mark and may be legally marketed in the countries of the European Union and the European Free Trade Association. The time required to obtain approval from a foreign country to market and sell Cytyc’s products may be longer or shorter than that required for FDA approval and the requirements may differ. No assurance can be given that such foreign regulatory approvals will be granted on a timely basis, or at all. In addition, there can be no assurance that Cytyc will meet the FDA’s export requirements or receive FDA export approval when such approval is necessary, or that countries to which the devices are to be exported will approve the devices for import. Cytyc’s failure to meet the FDA’s export requirements or obtain FDA export approval when required to do so, or to obtain approval for importation into various countries, could have a material adverse effect on Cytyc’s business, financial condition and results of operations.

##### Table of Contents

The laboratories that purchase the ThinPrep System, ThinPrep Imaging System and FullTerm are subject to extensive regulation under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”), which require laboratories to meet specified standards in the areas of personnel qualifications, administration, participation in proficiency testing, patient test management, quality control, quality assurance and inspections. Cytyc believes that the ThinPrep System, including the ThinPrep Imaging System and FullTerm, operate in a manner that will allow laboratories purchasing the device to comply with CLIA requirements. However, there can be no assurance that adverse interpretations of current CLIA regulations or future changes in CLIA regulations would not have an adverse effect on sales of the ThinPrep System, ThinPrep Imaging System and FullTerm.

Patents, Trademarks, Copyrights, Licenses and Proprietary Rights

Cytyc relies on a combination of patents, trademarks, trade secrets, copyrights and confidentiality agreements to protect its proprietary technology, rights and know-how. Cytyc pursues patent protection in the United States and files corresponding patent applications in certain foreign jurisdictions. Cytyc holds 120 issued United States patents, 190 pending United States patent applications, and corresponding foreign patents or patent applications relating to various aspects of Cytyc’s products, including the ThinPrep System, ThinPrep Imaging System, NovaSure System, MammoSite System, GliaSite System and other related technologies.

There can be no assurance, however, that pending patent applications will ultimately issue as patents or that the claims allowed in any of Cytyc’s existing or future patents will provide competitive advantages for its products or will not be successfully challenged or circumvented by competitors. In addition, Cytyc cannot be sure that its products or technologies do not infringe patents that may be granted in the future pursuant to pending patent applications or that Cytyc’s products do not infringe any existing patents or proprietary rights of third parties. In the event that any relevant claims of third-party patents are successfully enforced against Cytyc, Cytyc could be prevented from selling its products or could be required to obtain licenses from the owners of such patents or be required to redesign Cytyc’s products to avoid infringement. There can be no assurance that such licenses would be available or, if available, would be on terms acceptable to Cytyc or that Cytyc would be successful in any attempts to redesign Cytyc’s products or processes to avoid infringement. Cytyc’s failure to obtain these licenses or to successfully redesign its products would have a material adverse effect on its business, financial condition and results of operations.

Cytyc’s employees and third parties with whom Cytyc has entered into confidentiality agreements are obligated to maintain the confidentiality of Cytyc’s trade secrets and proprietary information. There can be no assurance that such obligations will effectively prevent disclosure of Cytyc’s confidential information or provide meaningful protection for Cytyc’s confidential information if there is unauthorized use or disclosure. At the same time, technology similar to Cytyc’s may be independently developed by its competitors.

Cytyc holds an exclusive worldwide license from DEKA Products, LP (“DEKA”) related to certain elements of the ThinPrep System. In addition, Cytyc is the exclusive licensee of certain patented technology for use in the field of diagnosis and treatment of breast cancer and for technology related to Cytyc’s GliaSite System, for the life of the related patents. Cytyc currently is obligated to pay royalties in varying amounts. Cytyc’s failure to maintain rights to such technology could have a material adverse effect on its business, financial condition and results of operations.

Cytyc presently has several trademarks, some of which have been registered with the United States Patent and Trademark Office and other comparable agencies worldwide. There can be no assurance that any copyrights or trademarks Cytyc owns will provide competitive advantages for Cytyc’s products or will not be challenged or circumvented by its competitors. Cytyc also holds unregistered copyrights on internally developed documentation and operating software developed for the ThinPrep System and ThinPrep Imaging System.

Litigation may be necessary to defend against claims of infringement, or to enforce Cytyc’s patents, copyrights, trademarks or trade secrets which could result in substantial cost to Cytyc and diversion of focus

away from its business. In addition, the laws of some foreign countries do not protect Cytyc’s proprietary rights to the same extent as do the laws of the United States, which may reduce the competitive advantage afforded by Cytyc’s intellectual property protection in certain jurisdictions.

Seasonality

Cytyc’s industry is subject to seasonal fluctuations in operating results and cash flows, which may reduce net sales and operating cash flows below annual averages. Cytyc experiences fluctuations in its business as a result of time of year, physicians’ vacation schedules and severe weather, which vary in severity from year to year. Therefore, comparison of the results of successive quarters may not accurately reflect trends or results for the full year.

Employees

As of March 31, 2007, Cytyc employed approximately 1,550 persons worldwide. Cytyc is not subject to any collective bargaining agreements, has never experienced a work stoppage and considers its relations with its employees to be good.

Financial Information Regarding Segment Reporting and Geographic Areas

Cytyc operates its business in three segments: domestic diagnostic products, domestic surgical products and international. Please refer to Note 2(t) “Segment and Enterprise-Wide Reporting” in the notes to Cytyc’s audited consolidated financial statements included in this joint proxy statement/prospectus.

Director Independence

The Cytyc board of directors has a standing audit committee, compensation committee, nominating and corporate governance committee, finance committee and venture investment committee. The Cytyc board of directors is composed of a majority of “independent” directors, and all of the committees are composed entirely of “independent” directors, as such term is defined in the listing standards of The Nasdaq Stock Market. The Cytyc board of directors has determined that the following directors are “independent,” as such term is defined in the listing standards of The Nasdaq Stock Market: William McDaniel, Walter E. Boomer, Sally W. Crawford, Brock Hattox, Joseph B. Martin, M.D., Ph.D., Marla S. Persky and Wayne Wilson. In addition, the audit committee is composed entirely of “independent” directors as such term is defined in Section 10A(m)(3) of the Exchange Act.

Properties

Cytyc’s executive offices, as well as its administrative, research, and certain manufacturing and distribution operations are located in a leased facility consisting of approximately 216,000 square feet in Marlborough, Massachusetts for a term of 15 years, beginning January 2004. In July 2006, Cytyc entered into a 12-year lease agreement for a building with approximately 146,000 square feet also located in Marlborough, Massachusetts, to be principally used as an additional manufacturing facility beginning in the first half of 2007. Cytyc has an option to lease an additional 30,000 square feet in this facility in June 2011. Cytyc owns approximately 2.7 acres of land and 46,000 square feet of facilities housing additional manufacturing operations in Londonderry, New Hampshire. Cytyc also leases a distribution facility consisting of approximately 37,000 square feet in Methuen, Massachusetts. Certain manufacturing, administrative, sales and marketing, research and development and operations for Cytyc’s NovaSure, MammoSite and GliaSite products are conducted at its Mountain View, California facility consisting of approximately 62,000 square feet. This lease expires in August 2012 and will remain in effect despite Cytyc’s 2007 consolidation of its Mountain View operations into its Costa Rica and Massachusetts operations. Cytyc’s primary manufacturing and operations facility for the NovaSure single-use devices consists of approximately 26,500 square feet in San Jose, Costa Rica. The lease for this facility expires in 2008, with an option to renew for two additional five-year terms. Cytyc also has a leased facility located in Alpharetta, Georgia consisting of certain clinical functions for Cytyc’s MammoSite and GliaSite Systems. This facility consists of approximately 12,400 square feet and expires in June 2007.

Legal Proceedings

On June 16, 2003, Cytyc filed a suit for Declaratory Judgment in United States District Court for the District of Massachusetts asking the court to determine and declare that certain of TriPath Imaging, Inc.’s (“TriPath”) patents are invalid and not infringed by Cytyc’s ThinPrep Imaging System. On June 17, 2003, TriPath announced that it had filed a lawsuit against Cytyc in the United States District Court for the Middle District of North Carolina alleging patent infringement, false advertising, defamation, intentional interference, unfair competition, and unfair and deceptive trade practices. In its complaint TriPath sought the issuance of a preliminary and permanent injunction enjoining Cytyc from infringing the asserted patents and to award unspecified damages, unspecified treble damages and attorneys’ fees, and the impounding and destruction of the alleged infringing products. As to the non-patent claims, TriPath sought unspecified damages, punitive damages and attorneys’

fees. The non-patent claims have been dismissed and the patent cases have since been consolidated into a single action. A hearing occurred on August 2, 2006 in the United States District Court for the District of Massachusetts to hear oral arguments on summary judgment motions. A trial is expected to occur beginning late October 2007. Cytyc continues to believe that the claims against it are without merit and intends to vigorously defend this suit. Given the stage and current status of the litigation, Cytyc is unable to reasonably estimate the ultimate outcome of this case.

On December 22, 2005, Xoft Inc. filed suit for Declaratory Judgment in the Northern District of California against Cytyc and Proxima Therapeutics, Inc., asking the court to determine and declare that U.S. Patent Nos. 5,913,813, 5,931,774, 6,083,148, 6,413,204, and 6,482,142 (the “’813”, “’774”, “’148”, “’204” and “’142” patents, respectively) are invalid and not infringed by Xoft’s brachytherapy device. Cytyc subsequently filed a counterclaim for infringement of the ‘813 and ‘204 patents and a motion to dismiss the ‘774, ‘148 and ‘142 patents. On October 23, 2006, the court granted Cytyc’s motion to dismiss the ‘774, ‘148 and ‘142 patents from the suit. Cytyc intends to protect its intellectual property and vigorously pursue its counterclaim of infringement. On April 27, 2007, the court issued a claim construction ruling. Xoft has filed several summary judgment motions to which Cytyc has responded and in some instances cross moved. Cytyc expects that this case may go to trial in late 2007. Given the early stage of the litigation, Cytyc is unable to reasonably estimate the ultimate outcome of this case.

Cytyc is subject to legal claims and assertions in the ordinary course of business. Although the outcomes of any other lawsuits and claims are uncertain, Cytyc does not believe that, individually or in the aggregate, any such lawsuits or claims will have a material adverse effect on its business, financial condition, results of operations or liquidity.

Risk Factors

If the merger is not completed, Cytyc will continue to be subject to the following risks:

Cytyc depends principally on the sale of a limited number of product lines.

Prior to Cytyc’s acquisitions of Novacept in March 2004, Proxima Therapeutics, Inc. (“Proxima”) in March 2005 and Adeza Biomedical Corporation (“Adeza”) in March 2007, Cytyc derived most of its revenues from sales of its ThinPrep processor, filters and other disposable supplies for use in gynecological and non-gynecological testing applications. As a result of the Novacept, Proxima and Adeza acquisitions, Cytyc manufactures and markets the NovaSure, MammoSite, GliaSite, FullTerm and TLi IQ Systems, which represented 37% of worldwide consolidated net sales in the year ended March 31, 2007. Nevertheless, Cytyc still relies heavily on sales of its ThinPrep products to generate a significant portion of its net sales and earnings. If Cytyc is unable to continue to successfully develop and commercialize its current products as well as other new or improved products, its business, sales and profits may be materially impaired.

In addition, in October 2003, an article in the New England Journal of Medicine suggested that the interval between screenings for cervical cancer could be extended from one year to three years for women over 30 who have had consistently negative results from previous screenings. If screening periods are extended as suggested, aggregate demand for testing is likely to decrease and if Cytyc is unable to successfully develop additional products, Cytyc’s business may be materially adversely affected. Furthermore, Cytyc may be required to obtain FDA approval for any other new or improved products that it is able to develop or acquire, and it may not be able to do so.

Cytyc’s sales are dependent on third-party reimbursement.

Widespread adoption of Cytyc’s ThinPrep, ThinPrep Imaging, NovaSure, MammoSite, GliaSite, FullTerm, The Fetal Fibronectin Test and TLi IQ Systems in the United States and other countries is dependent upon the

B-18

##### Table of Contents

ability of healthcare providers and laboratories to secure adequate reimbursement from third-party payors such as private insurance plans, managed care organizations, Medicare and Medicaid and foreign governmental healthcare agencies. Although a majority of managed care organizations in the United States have added the ThinPrep Pap Test, NovaSure, FullTerm and TLi IQ to their coverage and the MammoSite and GliaSite procedures are reimbursed by many private healthcare insurance and managed care payors, Cytyc cannot guarantee that reimbursement will increase or continue to be available, or that reimbursement levels will be adequate to enable healthcare providers and clinical laboratories in the United States and other countries to use Cytyc’s products instead of conventional methods or existing therapies, such as whole breast irradiation and brachy therapy, or the products of Cytyc’s competitors. Reimbursement and healthcare payment systems in international markets vary significantly by country and include both government-sponsored healthcare and private insurance. There can be no assurance that third-party payors will provide or continue to provide such coverage, that third-party reimbursement will be made available at an adequate level, if at all, for Cytyc’s products under any such overseas reimbursement system or that healthcare providers or clinical laboratories will use Cytyc’s products in lieu of other methods. Cytyc also will be required to secure adequate reimbursement for any new products it develops or acquires, and it may not be able to do so successfully.

Cytyc is dependent upon a relatively small number of large clinical laboratory customers in the United States for a significant portion of its sales of the ThinPrep System.

Cytyc is dependent upon a relatively small number of large clinical laboratory customers in the United States for a significant portion of its sales of the ThinPrep System, and its business may materially suffer if Cytyc is unable to increase sales to, or maintain its pricing levels with its existing customers and establish new customers both within and outside the United States. Due in part to a trend toward consolidation of clinical laboratories in recent years and the relative size of the largest United States laboratories, it is likely that a significant portion of ThinPrep System sales will continue to be concentrated among a relatively small number of large clinical laboratories.

Cytyc’s business faces intense competition from other companies.

Cytyc’s products face direct competition from a number of publicly-traded and privately-held companies. Some of Cytyc’s competitors are large companies that enjoy significant competitive advantages over Cytyc, including:

| • |  | significantly greater name recognition;

| • |  | established distribution networks;

| • |  | additional lines of products, and the ability to offer rebates or bundle products to offer discounts or incentives to gain competitive advantage;

| • |  | greater resources for product development, sales and marketing; and

| • |  | well-established products for procedures such as the radical mastectomy or traditional radiation therapy.

The markets Cytyc sells in are intensely competitive, subject to rapid change and significantly affected by new product introductions and other market activities of industry participants. Other companies may develop products that are superior to Cytyc’s or less expensive, or both. Improvements in existing competitive products or the introductions of new competitive products may reduce Cytyc’s ability to compete for sales, particularly if those competitive products demonstrate better safety or effectiveness, clinical results, ease of use or lower costs. The development, FDA approval and commercial marketing of competitive systems for cervical cancer screening, treatment of excessive menstrual bleeding, radiation treatment of early-stage breast cancer, and radiation treatment of patients with malignant brain tumors could have a material adverse effect on Cytyc’s

B-19

##### Table of Contents

business and financial condition. If Cytyc is unable to compete effectively against existing and future competitors and existing and future alternative treatments, Cytyc’s sales could decline and its business could be adversely affected.

The success of Cytyc’s business depends on its ability to protect its intellectual property rights.

Cytyc relies on a combination of patents, trade secrets, copyrights, trademarks and confidentiality agreements to protect its products’ proprietary technology, rights and know-how. Cytyc also is the exclusive licensee of certain patented technology for use in the field of cytology related to the ThinPrep System and in the treatment of any proliferative disease relating to Cytyc’s GliaSite System.

Cytyc owns all intellectual property rights with respect to the NovaSure System, the MammoSite System and the GliaSite System. However, the medical device industry in general, and the therapeutic use of devices employing radiofrequency energy, such as the NovaSure System, in particular, have been subject to extensive litigation and administrative proceedings regarding patents and other intellectual property rights.

If Cytyc fails to protect, defend and maintain the intellectual property rights with respect to any of its products or if Cytyc is subject to a successful third-party claim of infringement, the competitive position of these products could be impaired. In addition, infringement, interference and other intellectual property claims and proceedings, with or without merit, are expensive and time-consuming to litigate and could adversely affect Cytyc’s business, financial condition and operating results.

If breast surgeons, radiation oncologists and patients do not continue to adopt the MammoSite System as a preferred treatment for early-stage breast cancer, the intended benefits of Cytyc’s commercializing this product may not be realized and the market price of its common stock could decline.

One of Cytyc’s products acquired as a result of its acquisition of Proxima is the MammoSite System, which is used to treat early-stage breast cancer. At the time of acquisition, the MammoSite System was supported by less than four years of patient follow-up studies from the initial 43-patient study that was designed to gain clearance from the FDA and the one-year follow-up study from a 1,600-patient registry following the FDA clearance. Some of the existing data has been produced in studies that involve relatively small patient groups, and such data may not be reproduced in wider patient populations. Currently, with respect to Cytyc’s MammoSite System, Cytyc is competing against breast cancer treatment using external beam radiation, which has longer-term data on patient outcome.

Cytyc may have difficulty gaining further acceptance of the MammoSite System among breast surgeons, radiation oncologists and patients for a number of reasons including:

| • |  | the presence of competing products sold by companies with longer operating histories, more recognizable names and more established distribution networks;

| • |  | the introduction or existence of competing products or technologies that may be more effective, safer or easier to use than the MammoSite System;

| • |  | the results of long-term clinical studies relating to the effectiveness of the MammoSite System;

| • |  | the availability of alternative treatments or procedures that provide comparable levels of improvement in breast cancer treatment at a lower cost than the MammoSite System;

| • |  | breast surgeons, radiation oncologists and patient perceptions of the MammoSite System as compared to other treatments for breast cancer; and

| • |  | the continued availability of satisfactory reimbursement from healthcare payors for breast cancer treatment procedures.

B-20

##### Table of Contents

Cytyc believes that continued recommendation and support for the use of the MammoSite System by influential breast surgeons and radiation oncologists and treatment centers are essential for widespread market acceptance. If the MammoSite System does not continue to receive support from these key constituencies, or if longer-term data does not demonstrate continued support for the clinical efficacy of the MammoSite System, breast surgeons and radiation oncologists may not use, and hospitals and outpatient surgery centers may not purchase, the MammoSite System. If this occurs, the intended benefits of the acquisition, such as increased net sales, may not be realized and the market price of Cytyc’s common stock could decline.

Current levels of growth in the market for endometrial ablation procedures for the treatment of excessive menstrual bleeding may not be indicative of future growth.

Demand for newly introduced technologies or treatments can initially be exaggerated as supply increases to meet pre-existing demand. However, once the pre-existing demand is met, growth in the market may abruptly stop or significantly slow. Cytyc believes that some of the current growth in the market for new endometrial ablation procedures may be the result of a considerable pre-existing unmet demand for products of this nature. Cytyc cannot determine what portion of Novacept’s historical sales is attributable to this pre-existing demand, nor can Cytyc predict when, or at what rate, this demand may stop or decline in growth. Cytyc cannot assure you that it will be successful in continuing to attract physicians and women to use the NovaSure System, or whether or not evolving trends in the treatment of excessive menstrual bleeding will favor new endometrial ablation procedures as compared to traditional approaches. If the demand for treatments like the NovaSure System were to stop abruptly or begin to decline, Cytyc’s operating results and profitability could be adversely affected.

The success of Cytyc’s ThinPrep System depends upon the continued market acceptance of Cytyc’s ThinPrep System products.

Cytyc’s success and growth depends on the continued market acceptance of its ThinPrep System and ThinPrep Imaging System, including any follow-on applications of ThinPrep technology. The laboratory cost of using the ThinPrep System and ThinPrep Imaging System for cervical cancer screening, both together and individually, is higher than that of a conventional Pap smear and, Cytyc believes, competing liquid-based slide preparation systems. Due in part to increased competitive pressures in the healthcare industry to reduce costs, Cytyc’s ability to continue gaining market acceptance of the ThinPrep System and follow-on products depends on its ability to demonstrate that the higher cost of using the ThinPrep System is offset by (i) a reduction in costs often associated with conventional Pap smears or competing liquid-based slide preparation systems, such as inaccurate diagnoses and the need for repeat Pap smears, as well as (ii) the ability to conduct additional testing, such as testing for the HPV, Chlamydia trachomatis and Neisseria gonorrhea on samples collected in a ThinPrep vial of preservative. In particular, for the ThinPrep Imaging System, Cytyc needs to continue to work with healthcare providers, insurance companies and other third-party payors, and clinical laboratories to reinforce the known clinical efficacy and cost-effectiveness of the ThinPrep Imaging System products.

If Cytyc has difficulty in achieving and sustaining market acceptance of the products acquired as a result of Adeza, the intended benefits of Cytyc’s acquisition of such products may not be realized and the market price of its common stock could decline.

Cytyc’s products acquired as a result of its acquisition of Adeza is the FullTerm and the TLi IQ Systems. The commercial success of these products depends in large part on Cytyc’s ability to achieve and sustain market acceptance. Cytyc plans to expand sales of its TLi IQ System in hospitals and clinical laboratories and increase the related sales of the Fetal Fibronectin Test and other consumables used in conjunction with the TLi IQ System by convincing healthcare providers of the benefits of these products through various means, including through published papers, presentations at scientific conferences and additional clinical trials. If existing users of these products determine that these products do not satisfy their requirements, or if Cytyc’s competitors develop a product perceived to better satisfy their requirements, Cytyc’s sales of Fetal Fibronectin Tests and other consumables may decline.

B-21

##### Table of Contents

Cytyc also acquired a product candidate called Gestiva. Even if the FDA approves Gestiva, physicians may adopt Gestiva only if they determine, based on experience, clinical data, side effect profiles and other factors, that it is preferable to other products or treatments then in use. Acceptance of Gestiva among influential practitioners will be essential for market acceptance of Gestiva. If Cytyc’s products acquired from Adeza are unable to achieve or maintain broad market acceptance, the intended benefits of the Adeza acquisition, such as increased net sales, may not be realized and the market price of Cytyc’s common stock could decline.

Cytyc’s success depends on its ability to manage growth effectively.

The scope of Cytyc’s operations and facilities, the number of Cytyc’s employees and the geographic area of Cytyc’s operations have grown rapidly. If Cytyc is not able to manage its growth effectively, its business and financial condition will materially suffer. Cytyc’s growth may significantly strain its managerial, operational and financial resources and systems. To manage Cytyc’s growth effectively, Cytyc will have to continue to implement and improve additional management and financial systems and controls, and to effectively expand, train and manage its employee base.

Cytyc may not be able to successfully integrate future acquisitions.

Cytyc continually explores opportunities to acquire related businesses, some of which could be material to Cytyc. Cytyc’s ability to continue to grow may depend upon identifying and successfully acquiring attractive companies, effectively integrating such companies, achieving cost efficiencies and managing these businesses as part of Cytyc. Cytyc may not be able to effectively integrate acquired companies and successfully implement appropriate operational, financial and management systems and controls to achieve the benefits expected to result from these acquisitions. Cytyc’s efforts to integrate these businesses could be affected by a number of factors beyond Cytyc’s control, such as regulatory developments, general economic conditions, increased competition, the loss of customers resulting from the acquisitions and the assumption of unknown liabilities. In addition, the process of integrating these businesses could cause an interruption of, or loss of momentum in, the activities of Cytyc’s existing business and the loss of key personnel and customers. The diversion of management’s attention and any delays or difficulties encountered in connection with the integration of these businesses could negatively impact Cytyc’s business if any of the above adverse effects were to occur. Further, the benefits that Cytyc anticipates from any future acquisitions may not develop.

Future acquisitions may also harm Cytyc’s operating results, dilute its stockholders’ equity and create other financial difficulties for Cytyc.

Cytyc may, in the future, pursue acquisitions that it believes could provide it with new technologies, products or service offerings, or enable it to obtain other competitive advantages.

Acquisitions by Cytyc may involve some or all of the following financial risks:

| • |  | use of significant amounts of cash;

| • |  | potential dilutive issuances of equity securities;

| • |  | incurrence of debt or amortization expenses related to certain intangible assets; and

| • |  | future impairment charges related to diminished fair value of businesses acquired as compared to the price Cytyc pays for them.

Cytyc may not be successful in overcoming the risks described above or any other problems associated with future acquisitions. Any of these risks and problems could materially harm Cytyc’s business, prospects and financial condition. Additionally, Cytyc cannot guarantee that any companies it may acquire will achieve anticipated revenues or operating results.

B-22

##### Table of Contents

Cytyc is subject to the risk of product liability claims relating to its products.

Regardless of the technology employed, surgical procedures involve risk of complications, and companies that produce medical devices for use in surgical procedures are subject to risk of product liability litigation. Cytyc has become a party to legal proceedings involving injuries to patients that occurred when one of its products was used. Cytyc vigorously defends against any product liability claims that arise related to any of its products. However, there can be no assurance that any defense against alleged claims will be successful.

If one of Cytyc’s products is found to have caused or contributed to injuries or deaths, Cytyc could be held liable for substantial damages. Product liability insurance is in place for all of Cytyc’s products. However, Cytyc cannot assure that available insurance will be sufficient to cover damages from any possible claims. In addition, claims could adversely affect the reputation of the related product, which could damage its competitive position in the market. The sale and use of one of Cytyc’s diagnostic products could also lead to the filing of product liability claims if someone were to allege that one of Cytyc’s products contained a design or manufacturing defect that resulted in the failure to detect a disorder for which it was being used to screen or caused injuries to a patient. Any product liability claim brought against Cytyc, with or without merit, could result in the increase of Cytyc’s product liability insurance rates or the inability to secure additional coverage in the future. Also, even a meritless or unsuccessful product liability claim could be time consuming and expensive to defend, which could result in a diversion of management’s attention from Cytyc’s business and could adversely affect the perceived safety and efficacy of Cytyc’s products, as well as Cytyc’s financial condition and operating results.

Cytyc’s quarterly operating results may fluctuate.

Cytyc’s operating results have fluctuated significantly in the past on a quarterly basis. Cytyc’s operating results may fluctuate significantly from quarter to quarter in the future and Cytyc may experience losses in the future depending on a number of factors, including the extent to which its products continue to gain or maintain market acceptance, the rate and size of expenditures incurred as Cytyc expands its domestic and establishes its international sales and distribution networks, the timing and level of reimbursement for Cytyc’s products by third-party payors, seasonality and other factors, many of which are outside Cytyc’s control.

Cytyc may not be successful in growing its international sales, which could have a material adverse effect on its business and financial condition.

Cytyc believes the growth in its international sales is a key element to its future success. Cytyc commenced sales in countries outside the United States in 1998 and has grown its international sales to 11% of consolidated net sales for the year ended 2006. However, Cytyc cannot guarantee that it will successfully continue to develop international sales channels or capabilities that will enable it to generate significant revenue from international sales. Even though Cytyc has established international sales capabilities and has experienced growth in the international markets, Cytyc may not be able to obtain favorable third-party reimbursements and required regulatory approvals in foreign countries. While Cytyc believes it has developed a comprehensive international patent filing strategy, it has not secured patents in all foreign countries in which it currently sells or plans to sell its products. In some cases Cytyc’s ability to pursue patents in certain countries has lapsed. In those countries where Cytyc does have patents covering its products, it cannot guarantee that such patents may be successfully enforced against infringing products. If Cytyc fails to continue to increase international sales, its business and financial condition may suffer materially.

The increase in Cytyc’s international operations exposes Cytyc to additional operational challenges that it might not otherwise face.

As Cytyc increases its international operations, it will have to confront and manage a number of risks and expenses that it would not face if it conducted its operations solely in the United States. Any of these risks or expenses could cause a material adverse effect on Cytyc’s operating results. These risks and expenses include:

| • |  | difficulties in staffing, managing and operating an international operation as a result of, among other things, distance, language and cultural differences;

B-23

##### Table of Contents

| • |  | less flexible labor laws and regulations;

| • |  | expenses associated with customizing Cytyc’s products for clients in foreign countries;

| • |  | foreign currency exchange rate fluctuations;

| • |  | protectionist laws and business practices that favor local companies;

| • |  | political and economic instability in some international markets;

| • |  | multiple, conflicting and changing government laws and regulations (including, among other things, antitrust and tax requirements, international trade regulations and the Foreign Corrupt Practices Act);

| • |  | trade barriers;

| • |  | reduced protection for intellectual property rights in some countries; and

| • |  | potentially adverse tax consequences.

Cytyc’s operating results may be adversely affected by currency fluctuations.

Cytyc’s business outside the United States is conducted primarily in local currencies, except at its Costa Rica subsidiary, where the majority of business is conducted in U.S. dollars. Fluctuations in foreign currency exchange rates could affect Cytyc’s cost of goods and operating margins and could result in exchange losses. In addition, currency devaluation can result in a loss to Cytyc if it holds deposits of that currency. Hedging foreign currencies can be difficult, especially if the currency is not freely traded. Cytyc currently has no foreign exchange contracts, option contracts, or other foreign hedging arrangements. Cytyc currently estimates that risks associated with currency fluctuations are unlikely to have a material adverse effect on its operating results. However, Cytyc’s operating results may be adversely affected by currency fluctuations in the future, especially as Cytyc expands its international operations.

Cytyc’s operating results may be adversely affected as a result of restructuring operations and/or reductions in workforce.

In 2006, management approved restructuring plans designed to reduce future operating expenses by consolidating Cytyc’s Mountain View, California operations into Cytyc’s existing operations in Costa Rica and Massachusetts. This restructuring includes the elimination of positions, the incurrence of expenditures related to severance and facility-related costs, all of which has impacted and is expected to impact Cytyc’s operating results in 2006 and 2007. There can be no assurance that Cytyc’s current restructuring, as well as any potential future restructurings, and related transition issues, will not adversely affect Cytyc’s operations or customer perceptions. The uncertainty caused by such restructurings and integration-related events could result in reduced productivity by Cytyc’s remaining employees, which in turn may affect Cytyc’s revenue in the future.

In addition, any decision to limit investment in, dispose of or otherwise exit business activities may result in the recording of special charges, such as technology write-offs, workforce reduction costs, or charges relating to consolidation of excess facilities. Cytyc’s estimates with respect to the useful life or ultimate recoverability of Cytyc’s carrying basis of assets, including intangible assets, could change as a result of such decisions. Further, Cytyc’s estimates related to the liabilities for excess facilities are affected by changes in real estate market conditions. Additionally, Cytyc is required to perform goodwill impairment tests on an annual basis and during the year in certain circumstances. There can be no assurance that future goodwill impairment tests will not result in a charge to earnings.

Cytyc is highly dependent on key personnel.

Cytyc is highly dependent on the principal members of its management staff. Loss of its key personnel would likely impede achievement of Cytyc’s research and development, operational, or strategic objectives. To be successful, Cytyc must retain key employees and attract additional qualified employees.

B-24

##### Table of Contents

Cytyc’s reliance on single source or limited source suppliers could harm its business.

Cytyc currently obtains certain key components of its products, including the proprietary filter material and microscope slides used in the ThinPrep Pap Test, radioisotopes, certain balloons and other items used in the design and manufacture of the MammoSite System and the Iotrex liquid isotope used with the GliaSite System, from single or a limited number of sources due to technology, availability, price, quality and other considerations. Additionally, the NovaSure System utilizes several components that may become obsolete or no longer be manufactured. Cytyc also relies on a limited number of suppliers for both raw materials and components necessary for the manufacture of FullTerm, The Fetal Fibronectin Test, and TLi IQ System. Cytyc has no manufacturing capabilities for Gestiva and it may depend on third parties who are single source suppliers to manufacture Gestiva. Cytyc attempts to mitigate these risks by working closely with key suppliers regarding its supply needs and it has qualified backup vendors for several of its key components. Although Cytyc believes that alternative sources for these components are available, a supply interruption could harm its ability to manufacture its products until a new source of supply is identified and qualified. If Cytyc is unable to obtain sufficient quantities of key components that meet its quality and technical requirements at reasonable prices and in a timely manner, it will not be able to manufacture and sell its products on a timely and cost-competitive basis, which would materially and adversely affect its business and financial condition.

Cytyc’s lack of redundant manufacturing capabilities could harm Cytyc’s business.

Cytyc assembles all of its ThinPrep Processors, ThinPrep Imaging System, TLi IQ System and the single-use disposable devices in the NovaSure System, as well as performing final assembly and testing of its RF Controllers, MammoSite and GliaSite systems. In addition, Cytyc contracts with third-parties to manufacture its MammoSite System and GliaSite System. Cytyc has established a certain level of site redundancy on its core products, or has developed alternate sources. While Cytyc has made significant efforts to safeguard these core manufacturing processes, the loss or closure of any of these facilities, such as Cytyc’s planned closure of its Mountain View facility, or third-party manufacturing providers would impede Cytyc’s manufacturing and sales efforts, which would materially and adversely affect Cytyc’s business and financial condition.

Because the NovaSure and MammoSite Systems are manufactured in Costa Rica, Cytyc will be subject to the political and economic risks of doing business there.

Cytyc currently manufactures the Novasure System and MammoSite System in a facility in Costa Rica and recently signed a non-cancelable ten-year lease agreement for a building with approximately 164,354 square feet located in Alajuela, Costa Rica, which will be used as an additional manufacturing facility and office building. Cytyc cannot guarantee that the political, labor and economic climate in Costa Rica will remain sufficiently stable for uninterrupted manufacturing operations in that country. Cytyc’s operations relating to the NovaSure System and MammoSite System could be adversely affected by political unrest and Cytyc could also be harmed by strikes and other labor disruptions. Any of these events could result in increased costs or in disruptions of supply of the NovaSure and MammoSite disposable devices, or any other product or component Cytyc may elect to manufacture in Costa Rica in the future, which could harm Cytyc’s business, financial condition and operating results.

Cytyc is subject to numerous FDA laws and regulations, and non-compliance with such laws, as well as changes in such laws or future interpretations of such laws, could cause Cytyc to incur significant compliance costs and/or subject it to significant civil and criminal sanctions.

Cytyc’s products are subject to expansive FDA regulation. Complying with these requirements imposes significant expenses on Cytyc’s operations. If Cytyc fails to comply with applicable regulations, it could be subject to a wide range of civil and criminal enforcement sanctions, its promotional practices may be restricted, and its marketed products could be subject to recall or loss of FDA marketing claim approval.

B-25

##### Table of Contents

Cytyc cannot guarantee that it will obtain or maintain necessary regulatory approvals for its products.

The FDA regulatory approval process can be expensive, lengthy and uncertain for both original and supplemental approvals.

There can be no assurance that Cytyc will be able to obtain necessary regulatory clearances or approvals for any proposed future products or modifications of existing products. The failure to obtain clearances or approvals, loss of previously received clearances or approvals, or a failure to comply with existing or future regulatory requirements, would have a material adverse effect on Cytyc’s business, financial condition and operating results.

Any modifications to a device that has received a pre-market approval that affect its safety or effectiveness require a pre-market approval supplement or possibly a separate pre-market approval, either of which is likely to be time-consuming, expensive and uncertain to obtain. The FDA requires the device manufacturer to make and document its determination whether or not a pre-market approval or supplement is required, but the FDA can review the manufacturer’s decision. If the FDA requires Cytyc to seek one or more pre-market approval supplements or new pre-market approvals for any modification to a previously approved device, Cytyc may be required to cease marketing or to recall the modified device until it obtains approval, and Cytyc may be subject to significant criminal and/or civic sanctions, including but not limited to, regulatory fines or penalties.

If Cytyc or its contract manufacturers fail to comply with the FDA’s Quality System Regulation, manufacturing operations could be interrupted, and Cytyc’s product sales and operating results could be adversely affected.

Cytyc’s design and manufacturing processes are required to comply with the FDA’s Quality System Regulation, which covers the procedures and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of Cytyc’s devices. The FDA enforces its Quality System Regulation through unannounced inspections. If one of Cytyc’s manufacturing facilities fails an inspection, operations and manufacturing could be disrupted. Failure to take adequate and timely corrective action in response to an adverse inspection could force a shutdown of these manufacturing operations or a recall of the product. If Cytyc shuts down manufacturing operations or recalls its products, it may lose customers and experience a decline in its revenues.

Cytyc’s products may be subject to recalls even after receiving FDA clearance or approval, and if a recall occurs, the reputation of Cytyc’s products and its operating results could be adversely affected.

The FDA and similar governmental bodies in other countries have the authority to require the recall of Cytyc’s products in the event of material deficiencies or defects in design or manufacture. A government mandated or voluntary recall by Cytyc could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling. Any recall could harm the reputation of Cytyc’s products and adversely affect Cytyc’s financial condition and operating results.

Some of Cytyc’s activities may subject Cytyc to risks under federal and state laws prohibiting “kickbacks” and false or fraudulent claims.

Cytyc is subject to the provisions of a federal law commonly known as the “Medicare/Medicaid anti-kickback law,” and several similar state laws, which prohibit payments intended to induce physicians or others either to refer patients or to acquire or arrange for or recommend the acquisition of healthcare products or services. While the federal law applies only to referrals, products or services for which payment may be made by a federal healthcare program, state laws often apply regardless of whether federal funds may be involved. These laws constrain the sales, marketing and other promotional activities of manufacturers of medical devices, such as Cytyc, by limiting the kinds of financial arrangements, including sales programs, with hospitals, physicians,

B-26

##### Table of Contents

laboratories and other potential purchasers of medical devices. Other federal and state laws generally prohibit individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent, or are for items or services that were not provided as claimed. Anti-kickback and false claims laws prescribe civil and criminal penalties for noncompliance that can be substantial. While Cytyc continually strives to comply with these complex requirements, interpretations of the applicability of these laws to marketing practices is ever evolving and even an unsuccessful challenge could cause adverse publicity and be costly to respond to, and thus could have a material adverse effect on Cytyc’s business, operating results and financial condition.

Certain provisions of Cytyc’s certificate of incorporation, bylaws and Delaware law may delay or prevent a change in control of Cytyc.

Cytyc’s certificate of incorporation, bylaws and Delaware law contain provisions that may enable Cytyc’s board of directors to resist a change in control of Cytyc. These provisions include:

| • |  | a staggered board of directors;

| • |  | limitations on persons authorized to call a special meeting of stockholders;

| • |  | the authorization of undesignated preferred stock, the terms of which may be established and shares of which may be issued without stockholder approval;

| • |  | advance notice procedures required for stockholders to nominate candidates for election as directors or to bring matters before an annual meeting of stockholders; and

| • |  | a stockholder rights agreement or “poison pill.”

In addition, Cytyc is subject to the anti-takeover provisions of Section 203 of the DGCL, which may prohibit large stockholders, in particular those owning 15% or more of Cytyc’s outstanding voting stock, from merging or consolidating with Cytyc except under certain circumstances.

These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control of Cytyc. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and cause Cytyc to take other corporate actions stockholders desire.

The implementation of SFAS No. 123R has reduced and may continue to reduce Cytyc’s reported earnings, which could result in a decline in Cytyc’s stock price.

As part of Cytyc’s compensation to employees, it issues equity awards, primarily in the form of stock options. Many of the companies within Cytyc’s industry and with whom Cytyc competes for skilled employees use stock-based compensation as a means to attain these employees. While Cytyc has structured the estimated cost of its equity program to be comparable to other companies within its industry and similar to its size, not all companies use equity awards as part of their compensation packages nor do they issue the same level of equity awards. As a result, the impact of the January 1, 2006 implementation of SFAS No. 123R may be more significant for Cytyc as compared to other companies. In addition, if Cytyc unexpectedly hires additional employees or acquires another company, the impact of the implementation of SFAS No. 123R may be more significant for Cytyc than previously forecasted. To the extent investors believe the costs incurred for SFAS No. 123R are higher than those incurred by other companies, Cytyc’s stock price could be negatively impacted.

CYTYC MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion is provided by Cytyc’s management as its analysis of Cytyc’s financial condition and results of operations. This analysis should be read in conjunction with the following information included in this joint proxy statement/prospectus: (i) the audited consolidated financial statements of Cytyc and its subsidiaries as of December 31, 2006 and 2005 and for each of the three years ended December 31, 2006, 2005, and 2004, and the notes thereto; and (ii) the condensed consolidated financial statements (unaudited) of Cytyc and its subsidiaries as of March 31, 2007 and 2006 and for each of the three months ended March 31, 2007 and 2006, and the notes thereto.

Overview

Cytyc Corporation is a diversified diagnostic and medical device company that designs, develops, manufactures, and markets innovative and clinically effective diagnostic and surgical products. Cytyc’s products cover a range of cancer and women’s health applications, including cervical cancer screening, pre-term birth risk assessment, treatment of excessive menstrual bleeding, radiation treatment of early-stage breast cancer, and radiation treatment of patients with malignant brain tumors. Cytyc operates its business in three reportable segments: domestic diagnostic products, domestic surgical products and international. Cytyc’s domestic diagnostic products segment develops and markets the ThinPrep® System in the United States primarily for use in cytology testing applications, such as cervical cancer screening, and FullTerm™, The Fetal Fibronectin Test, acquired as part of Cytyc’s purchase of Adeza Biomedical Corporation (“Adeza”), which offers clinical and cost benefits for the assessment of the risk of pre-term birth. Cytyc’s domestic surgical products segment develops and manufactures the NovaSure® System, an innovative endometrial ablation device to treat menorrhagia, or excessive menstrual bleeding, the MammoSite® Radiation Therapy System, a device for the treatment of breast cancer that positions radiation sources directly into the post-lumpectomy site to optimize radiation treatment delivery while minimizing damage to healthy tissue, and the GliaSite® Radiation Therapy System for the treatment of malignant brain tumors. The domestic surgical segment, as part of Cytyc’s purchase of Adiana, Inc. (“Adiana”), acquired the Adiana Complete Transcervical Sterilization System® (“TCS”), which is a form of permanent female contraception intended as an alternative to tubal ligation and for which Cytyc is in the process of seeking a pre-market approval (“PMA”) from the Food and Drug Administration (“FDA”). The domestic surgical products segment markets these products in the United States. Cytyc’s international segment markets its diagnostic and surgical products outside of the United States.

On March 16, 2007, Cytyc acquired all of the fully-diluted equity of Adiana, and on March 19, 2007, purchased a majority of the outstanding common shares of Adeza and completed the acquisition as of April 2, 2007. Cytyc’s operating results include the results of Adiana and Adeza from March 17, 2007 and March 20, 2007, respectively.

Critical Accounting Estimates

Cytyc management’s discussion and analysis of Cytyc’s financial condition and results of operations are based upon Cytyc’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires Cytyc to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. A “critical accounting estimate” is one which is both important to the portrayal of Cytyc’s financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Cytyc continuously evaluates its critical accounting estimates. Cytyc bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Valuation of Long-Lived Assets, Intangibles and Goodwill—Tangible and intangible assets acquired in a business combination, including acquired in-process research and development, are recorded under the purchase method of accounting at their estimated fair values at the date of acquisition. The fair values of acquired assets are determined by management using relevant information and assumptions and assisted, in certain situations, by independent appraisers. Fair value of acquired intangible assets is generally calculated as the present value of estimated future cash flows using a risk-adjusted discount rate, which requires significant management judgment with respect to revenue and expense growth rates, analyses of project accomplishments, assessment of overall contributions, project risks and the selection and use of an appropriate discount rate. Amortization of all of Cytyc’s intangible assets with defined lives, including those acquired individually, is calculated either using the straight-line or cash flow method. The cash flow method requires management’s estimate of net cash flows over the life of the intangible asset, reflecting the pattern in which the economic benefits of the intangible asset are expected to be consumed, and is subject to change.

Prior to 2007, Cytyc allocated amortization of all of its intangible assets to research and development within Cytyc’s condensed consolidated statements of income as the developed technology has benefited multiple line items (i.e., cost of sales and research and development) and any allocation that would have been made to cost of sales was not deemed to be material. During 2007, Cytyc acquired a significant amount of developed technology ($142.8 million) as part of its acquisition of Adeza and is including the amortization of such developed technology within cost of sales based upon its intended use. For the amortization of Cytyc’s other developed technology, beginning in 2007, Cytyc is allocating the majority to cost of sales based upon Cytyc’s determination that such developed technology is primarily being used to generate sales of Cytyc’s products. A portion of the amortization expense also will be allocated to research and development based upon Cytyc’s determination that such developed technology is primarily being utilized to support Cytyc’s research and development efforts (e.g., FirstCyte Breast Test).

Cytyc assesses the impairment of long-lived assets, identifiable intangible assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable and at least annually in the case of goodwill. If it is determined that the carrying value of long-lived assets, intangible assets or goodwill might not be recoverable based upon the existence of one or more indicators of impairment, Cytyc would measure any impairment based on a projected discounted cash flow method if the undiscounted cash flows did not exceed the carrying value of such assets. No significant impairment charges have been recorded to date. Cytyc is required to perform an impairment review for goodwill on an annual basis, or earlier if indicators of potential impairment exist. Based on Cytyc’s impairment review during 2006, the carrying amount of goodwill did not exceed its fair value and, accordingly, no impairment loss exists. At March 31, 2007, Cytyc had $916.7 million of net intangible assets, of which $595.0 million represented goodwill. An impairment of Cytyc’s intangible assets could result in a material, non-cash expense in Cytyc’s consolidated statement of income.

Income Taxes and Deferred Taxes—Cytyc files income tax returns in eleven countries as well as many states and other localities. Cytyc must estimate its income tax expense after considering, among other factors, differing tax rates between jurisdictions, allocation factors, tax credits, non-deductible items and changes in enacted tax rates. A 1% change in Cytyc’s 2007 effective income tax rate would have the effect of changing net (loss) income by approximately $0.6 million or less than $0.01 per common share. The carrying value of Cytyc’s deferred tax assets assumes that Cytyc will be able to generate sufficient future taxable income in certain tax jurisdictions, based on estimates and assumptions, to fully recover the net carrying value of the assets. If these estimates and related assumptions change in the future, Cytyc may be required to record a valuation allowance against its deferred tax assets resulting in additional income tax expense in Cytyc’s consolidated statement of (loss) income.

Effective January 1, 2007, Cytyc adopted Financial Accounting Standards Board Interpretation (“FIN”) No. 48, Accounting for Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109. FIN No. 48 requires significant judgment as to what constitutes a tax position as well as assessing the outcome of each tax position. Changes in facts or judgments surrounding recognition or measurement will result in a tax benefit or charge to Cytyc’s consolidated statement of (loss) income.

Legal Proceedings—Cytyc is involved in various legal actions, the outcomes of which are not within Cytyc’s complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, which, if granted, would require significant expenditures. Cytyc records a liability in its consolidated financial statements for these actions when a loss is known or considered probable and the amount can be reasonably estimated. Cytyc reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in the consolidated financial statements. Cytyc’s significant legal proceedings are discussed above under “Information About Cytyc—Legal Proceedings.”

Stock-based Compensation—In December 2004, the FASB issued SFAS No. 123R, Share-Based Payment. SFAS No. 123R requires all stock-based compensation to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. Cytyc adopted SFAS No. 123R on January 1, 2006 using the modified prospective method and accordingly, prior period amounts have not been restated. In order to determine the fair value of Cytyc’s stock options and employee stock purchase plan shares, Cytyc is using the Black-Scholes option pricing model and is applying the multiple-option valuation approach to the stock option valuation. Cytyc is recognizing stock-based compensation expense on a straight-line basis over the requisite service period of the awards for options granted following the adoption of SFAS No. 123R. For unvested stock awards outstanding as of January 1, 2006, Cytyc will continue to recognize stock-based compensation expense using the accelerated amortization method prescribed in FIN No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans.

Cytyc’s estimates of the fair value of equity awards will be affected by the future market price of Cytyc’s common stock, as well as the actual results of certain assumptions used to value the equity awards. These assumptions include, but are not limited to, the related income tax impact, the expected volatility of the common stock, the number of stock options to be forfeited and exercised by employees, and the expected term of options granted.

As noted above, Cytyc determines the fair value of stock options and employee stock purchase plan shares by using the Black-Scholes option pricing model and applying the multiple-option valuation approach to the stock option valuation. The options have graded-vesting on an annual basis over an average vesting period of four years. In applying the multiple-option approach, Cytyc separately values each option “tranche” based on when the tranche vests. Cytyc estimates the expected option term by calculating the average period of time before the employees exercise their options and adds this to the vesting period of each tranche. Historically, this period of time has averaged one year from the date the options vest. The expected term of employee stock purchase plan shares is the average of the remaining purchase periods under each offering period. For equity awards granted prior to the adoption of SFAS No. 123R, Cytyc estimated the volatility of the common stock using historical volatility. For equity awards granted since January 1, 2006, Cytyc is estimating the volatility of the common stock using a combination of historical and implied volatility, as discussed in Staff Accounting Bulletin No. 107, Considering the Information Between SFAS No. 123R and Certain Securities and Exchange Commissions Rules and Regulations. By using this combination, Cytyc is taking into consideration the historical realized volatility, as well as factoring in estimates of future volatility that it believes will differ from historical as a result of Cytyc’s product diversification over the last two years, the market performance of Cytyc’s common stock, the volume of activity of the underlying shares, the availability of actively traded options of Cytyc’s common stock, and overall market conditions.

Cytyc determines the risk-free interest rate used in the Black-Scholes option pricing model by looking at historical U.S. Treasury zero-coupon bond issues with remaining terms equal to the expected terms of the equity awards. In addition, Cytyc uses an expected dividend yield of zero in the option valuation model, because Cytyc does not expect to pay any cash dividends in the foreseeable future. Lastly, in accordance with SFAS No. 123R, Cytyc is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. In order to determine an estimated pre-vesting option forfeiture rate, Cytyc used historical forfeiture data. This estimated forfeiture rate has been applied to all unvested options outstanding as of January 1, 2006 and to all options granted since January 1, 2006. Therefore, stock-based compensation expense is recorded only for those options that are expected to vest.

In February 2007, Cytyc issued 160,700 performance-based stock units (“performance shares”) that vest over a three-year period based upon specific future performance milestones. A grantee may also earn, over the course of three years, a total number of shares ranging from 0% to 175% of the number of shares equal to his or her initial grant of performance shares, which range is based on the actual achievement of the performance milestones. The market price of Cytyc’s common stock on date of grant was $30.44. Each period Cytyc will assess its estimate of the probability that such performance milestones will be met and, if necessary, will adjust the related stock-based compensation expense. Currently Cytyc is recording stock-based compensation expense for these equity awards over the three-year vesting period assuming all future performance milestones will be met.

The statements of (loss) income classification of Cytyc’s stock-based compensation is consistent with the classification of Cytyc’s cash compensation expense related to the salaries of the employee option holders. Total stock-based compensation recognized in Cytyc’s condensed consolidated statements of (loss) income for the three months ended March 31, 2007 and 2006 is as follows:

|  | Three Months Ended March 31,
|  | 2007 |  | 2006
|  | (in thousands)
Cost of sales |  | $ | 261 |  | $ | 361
Research and development |  |  | 609 |  |  | 844
Sales and marketing |  |  | 1,915 |  |  | 2,651
General and administrative |  |  | 1,567 |  |  | 2,169
Total stock-based compensation expense |  | $ | 4,352 |  | $ | 6,025

As of March 31, 2007, total unrecognized stock-based compensation expense relating to unvested employee stock awards, adjusted for estimated forfeitures, was $33.5 million. This amount is expected to be recognized over a weighted-average period of 2.6 years. If actual forfeitures differ from current estimates, total unrecognized stock-based compensation expense will be adjusted for future changes in estimated forfeitures.

The above list is not intended to be a comprehensive list of all of Cytyc’s accounting estimates. In many cases, the accounting treatment of a particular transaction is specifically dictated by generally accepted accounting principles, with little need for management’s judgment in their application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. See Cytyc’s audited consolidated financial statements and notes thereto included in this joint proxy statement/prospectus which contain accounting policies and other disclosures required by generally accepted accounting principles in the United States.

Stock Option Review and Restatement of Financial Statements

During the first quarter of 2007, Cytyc became aware of a report prepared by an independent equity research firm suggesting that Cytyc was at an elevated risk for issues with the dating of stock option exercises prior to the effective date of the Sarbanes-Oxley Act of 2002. At the request of the General Counsel and the Chief Executive Officer, the audit committee (the “audit committee”) of the Cytyc board of directors, with the assistance of independent outside counsel and Cytyc’s internal audit department, conducted a voluntary review of circumstances relating to the exercising of employee stock options. As a result of that review, the audit committee concluded with respect to two current executives—the Chief Executive Officer and the General Counsel—that on several occasions during the period from 1996 through 2002, qualified incentive stock options granted under Cytyc’s stock option plans (the “Plans”) were reported as having been exercised before all of the actions required by the Plan to effect such an exercise were completed. To the extent an exercise can be reported as occurring before all the required actions are complete, an option holder has the opportunity to obtain an exercise date using hindsight (hereafter referred to as “exercise back-dating” or “look-back”) and thereby exercise on a date with a preferable market price. In connection with the above review, the Cytyc board of directors concluded that the affected executives did not understand the potential implications of their actions to

Cytyc. The executives have reimbursed Cytyc for additional amounts which might have been due to Cytyc, as well as a portion of the costs of the audit committee’s review. The Cytyc board of directors continues to have full confidence in the integrity of the affected individuals.

Subsequent to the completion of Cytyc’s 2006 consolidated financial statements and the filing of its 2006 Annual Report on Form 10-K, Cytyc determined that variable award accounting should be considered for certain employee stock options as a result of the exercises described above. Based on additional research performed by Cytyc and accounting specialists engaged by counsel to the audit committee, Cytyc determined that all stock options granted to the Chief Executive Officer and General Counsel and still outstanding at any date following the first in a series of exercises by each of these executives reported as occurring before all the required actions were completed during the period 1996 through August 28, 2002 (the date the look-back practice was no longer available based on the change in the SEC’s filing requirements reducing the reporting window for equity share activity) are subject to variable award accounting because the exercise price of those options was not fixed on the date of grant. Under variable award accounting, non-cash, stock-based compensation expense is recognized based on the difference between the market price of Cytyc’s common stock for each affected period and the exercise price of the option. Accordingly, Cytyc has recorded stock-based compensation expense or benefit for each of the years ended December 31, 1996 through 2002 (noting there was no compensation expense or benefit for any years subsequent to 2002 related to these stock options) taking into consideration the vesting provisions of the award and the timing of exercise.

Cytyc has analyzed the circumstances surrounding exercises by other executives and other non-officer employees for purposes of determining whether any of the exercise activity under review would result in accounting consequences. Based on this analysis, Cytyc has concluded that single stock option grants to one current and one former executive (the “Two Other Executives”) were modified, from an accounting perspective, on the date of exercise in 2000. As a result, Cytyc has recorded a stock-based compensation charge during the year ended December 31, 2000, based on the excess of the quoted market price of Cytyc’s common stock as of the modification date over the option exercise price for those options.

The restatement impacts net income in the year ended December 31, 2002 (as presented in “Selected Historical Financial Data of Cytyc”) and impacts net (loss) income in the years ended December 31, 1996 through 2002 (as discussed in Note 15 to Cytyc’s audited consolidated financial statements). The cumulative impact to net (loss) income in the years ended December 31, 1996 through 2002 is reflected in an adjustment to retained earnings in Cytyc’s consolidated balance sheets, with a related tax impact on deferred tax assets. There was no restatement required for Cytyc’s consolidated statements of income for the years ended December 31, 2003, 2004, 2005 or 2006.

Separately, in light of the number of publicly-disclosed stock option grant back-dating activities at other companies, during 2006 Cytyc’s internal audit department, acting under the direction and supervision of the audit committee of the board of directors, reviewed Cytyc’s employee stock option granting practices and no inappropriate grant dates were identified. During 2007, such work of Cytyc’s internal audit department was reviewed by the independent outside counsel of the audit committee, which performed certain additional procedures and also did not identify any inappropriate grant dates.

Total Company |  | $ | 168.9 |  | $ | 140.5 |  | 20 | %

(1) | Cytyc’s net sales for the three months ended March 31, 2007 include the results of Adeza from the date of acquisition (March 19, 2007, the date on which Cytyc owned the majority of Adeza’s outstanding shares).

(2) | The international segment includes international sales of Cytyc’s diagnostic products of $18.0 million and $14.0 million during the three months ended March 31, 2007 and 2006, respectively. This segment also includes international sales of Cytyc’s surgical products of $2.4 million and $1.1 million during the three months ended March 31, 2007 and 2006, respectively.

Net sales for each segment as a percentage of total consolidated net sales is as follows (dollars in millions) for the three months ended March 31, 2007 and 2006:

Cytyc’s domestic surgical net sales increased 33% during the three months ended March 31, 2007 as compared to the same period of 2006, primarily reflecting growth in unit sales and increased average sales price of single-use disposable devices of both the NovaSure System and MammoSite Radiation Therapy System. Domestic net sales of Cytyc’s NovaSure System represented 85% and 84% of the domestic surgical products segment’s net sales during the three months ended March 31, 2007 and 2006, respectively. Net sales of the MammoSite Radiation Therapy System represented 13% and 14% of the domestic surgical products segment’s net sales during the three months ended March 31, 2007 and 2006, respectively. During the three months ended March 31, 2007, no customer represented more than 10% of total domestic surgical net sales.

B-33

##### Table of Contents

Cytyc’s domestic diagnostic net sales increased 11% during the three months ended March 31, 2007 as compared to the same period of 2006, due primarily to the continued increase in adoption and utilization of the ThinPrep Imaging System across Cytyc’s customer base. In addition, net sales during the three months ended March 31, 2007 include $3.6 million of net sales of FullTerm, The Fetal Fibronectin Test, acquired as part of Cytyc’s purchase of Adeza, from the date of acquisition. During the three months ended March 31, 2007, two customers represented 15% and 13%, respectively, of total domestic diagnostic net sales.

Net sales in Cytyc’s international segment, which is comprised of net sales to customers outside the United States of both diagnostic and surgical products, increased 35% during the three months ended March 31, 2007 as compared to the same periods of 2006, primarily reflecting higher unit sales of the ThinPrep Pap Test and the NovaSure single-use disposable devices. During the three months ended March 31, 2007, no customer represented more than 10% of total international net sales.

During the three months ended March 31, 2007 and 2006, no customer represented 10% or more of Cytyc’s consolidated net sales.

Gross Margin

Cytyc’s gross margin was 75% during the three months ended March 31, 2007 and was 79% during the three months ended March 31, 2006. Cytyc’s gross margin decreased during the three months ended March 31, 2007, primarily as a result of: (i) Cytyc’s inclusion within cost of sales of $3.2 million of non-cash amortization expense related to its intangible assets during the three months ended March 31, 2007; (ii) slightly lower gross margins in Cytyc’s domestic diagnostic products segment as a result of increased placements of the ThinPrep Imaging System which generally carry lower gross margins than domestic sales of the ThinPrep Pap Test; (iii) slightly lower gross margins in Cytyc’s domestic surgical products segment due to costs associated with the on-going closure of its facility in Mountain View, California, as well as the impact of certain sales programs; and (iv) growth in Cytyc’s international segment, which generally carries lower margins than sales in the United States, though there was an increase in gross margins within the international segment in the three months ended March 31, 2007 as compared to the same period of 2006, reflecting product mix.

Operating Expenses

Total operating expenses increased to $159.8 million for the three months ended March 31, 2007, an increase of 148% as compared to $64.4 million for the same period of 2006, primarily as a result of the in-process research and development charges totaling $89.5 million associated with Cytyc’s first quarter 2007 acquisitions of Adeza and Adiana, as well the incremental operating expense from these two subsidiaries. The following is a summary of operating expenses for the three months ended March 31, 2007 and 2006:

|  | Three Months Ended March 31, |

Research and Development

Cytyc’s core research and development strategy is to enhance its existing product lines, such as the ThinPrep Imaging System, the NovaSure System, the MammoSite Radiation Therapy System and the GliaSite Radiation Therapy System, through operational enhancements and cost reductions, as well as to continue to develop additional innovative medical diagnostic and surgical devices and therapeutic applications for cancer and women’s health, through Cytyc’s existing intellectual property, as well as through the acquisition of new intellectual property. Cytyc’s research and development costs slightly decreased by $0.6 million to $9.7 million for the three months ended March 31, 2007, a decrease of 6% as compared to the same period of 2006, primarily reflecting: (i) a $2.0 million reduction of non-cash amortization as a result of recording this amortization within cost of sales during the three months ended March 31, 2007, where all such non-cash amortization had been included within research and development expenses in prior periods; partially offset by (ii) $0.5 million of incremental expenses during the three months ended March 31, 2007 from the inclusion of the operating results of Adeza and Adiana in Cytyc’s consolidated results from the dates of acquisition; (iii) incremental expenses during the three months ended March 31, 2007 supporting the MammoSite Radiation Therapy System; and (iv) increased engineering costs to continue to improve the NovaSure System and the MammoSite Radiation Therapy System and to develop related technologies to grow Cytyc’s product lines.

In-Process Research and Development

As part of the allocation of the purchase prices of Adeza and Adiana from the dates of acquisition in March 2007, all intangible and tangible assets were identified and valued. It was determined that certain developed and in-development technology had ongoing value. As a result of this identification and valuation process, Cytyc allocated $43.5 million and $46.0 million, respectively, of the purchase prices to in-process research and development projects during the three months ended March 31, 2007. This allocation represents the estimated fair values based on risk-adjusted cash flows related to incomplete research and development activities associated with: (i) Adeza’s development of Gestiva, which is currently pending final approval from the FDA, as well as Adeza’s induction of labor diagnostic product which is in an earlier stage of development than Gestiva; and (ii) Adiana’s TCS System for which Cytyc is in the process of seeking a PMA from the FDA.

The rates utilized to discount the net cash flows to their present value was based on estimated weighted-average cost of capital calculations. A discount rate of 14% was used to value the in-process research and development projects purchased as part of the Adeza acquisition and a discount rate of 26% was used to value the in-process research and development projects purchased as part of the Adiana acquisition. These discount rates were higher than Cytyc’s weighted-average cost of capital due to, as applicable, the earlier-stage overall life cycles of the acquired products, the inherent uncertainties surrounding the outcome of the upgrade and development projects and successful commercialization and development of the acquired assets, the useful life of the acquired technology, the profitability levels of such technology and the uncertainty of technological advances that were unknown at that time.

As of the respective dates of acquisition of Adeza and Adiana, the acquired in-process research and development was charged to expense in the condensed consolidated statement of loss for the three months ended March 31, 2007.

Sales and Marketing

Sales and marketing costs increased $1.1 million to $41.2 million for the three months ended March 31, 2007, an increase of 3% as compared to the same period of 2006, primarily due to incremental sales and marketing costs of Cytyc’s domestic surgical products business. These costs reflect $1.2 million of additional commissions incurred during the three months ended March 31, 2007 on increased sales volume, as well as costs associated with the continued growth in the sales force to support increased sales of Cytyc’s surgical products. These higher sales and marketing costs were partially offset by a $0.7 million reduction in non-cash stock-based compensation expense during the three months ended March 31, 2007, as compared to the same period in 2006.

General and Administrative

General and administrative costs increased $5.4 million to $19.4 million for the three months ended March 31, 2007, an increase of 39% as compared to the same period of 2006, primarily due to: (i) increased personnel and facility costs to support the growth of Cytyc’s business; and (ii) increased efforts to enhance Cytyc’s management information systems. These increased costs were partially offset by a $0.6 million reduction in non-cash stock-based compensation expense during the three months ended March 31, 2007 as compared to the same period in 2006.

Cytyc recorded interest expense of $2.4 million and $1.8 million for the three months ended March 31, 2007 and 2006, respectively, related primarily to: (i) $1.8 million in both periods from Cytyc’s 2.25% convertible notes due 2024, which were issued on March 22, 2004, including amortization of $0.4 million of deferred financing costs for in both periods associated with the issuance of these notes; and (ii) $0.6 million of interest expense related to Cytyc’s borrowing on its line of credit facility totaling $200.5 million as of March 31, 2007, to facilitate the purchases of Adiana and Adeza. Interest income increased to $2.6 million for the three months ended March 31, 2007, as compared to $1.8 million for the same period of 2006, as the average interest rate and the average total balance of Cytyc’s cash, cash equivalents and investment securities were higher during the three months ended March 31, 2007 as compared to the same period of 2006. Cytyc recognized other income of $0.8 million during the three months ended March 31, 2007 as compared to other expense of ($0.1) million during the three months ended March 31, 2006, primarily as a result of a gain of $0.5 million on one of Cytyc’s private equity investments.

Income Taxes

Exclusive of the effects of the non-deductible in-process research and development charges incurred in connection with Cytyc’s acquisitions of Adeza and Adiana in March 2007 Cytyc’s effective tax rate would have been 33.4% including the recognition of a tax benefit related to an examination that closed during the period. The effective tax rate was 36.5% for the three months ended March 31, 2006. Cytyc believes it has adequate liabilities for uncertain tax positions. If Cytyc ultimately determines that these liabilities are greater or less than the amounts paid, it will adjust the liabilities for uncertain tax positions and recognize a tax benefit or charge in the consolidated statement of (loss) income during the period in which Cytyc makes the determination or, if the adjustments relate to unrecognized tax benefits for deferred tax assets recorded in connection with an acquisition, Cytyc will adjust the carrying value of goodwill. Cytyc estimates its effective tax rate for 2007 will be in the range of 55% to 56% and, exclusive of the effects of the in-process research and development charges, Cytyc estimates its effective tax rate will be in the range of 35% to 36%.

(2) | The international segment includes international sales of Cytyc’s diagnostic products of $62.3 million, $50.3 million and $40.5 million in 2006, 2005 and 2004, respectively. This segment also includes international sales of Cytyc’s surgical products of $6.0 million, $2.8 million, and $1.1 million in 2006, 2005, and 2004 respectively.

Net sales for each segment as a percentage of total consolidated net sales is as follows (dollars in millions):

Cytyc’s domestic surgical products net sales increased 43% in 2006 as compared to 2005 and increased 130% in 2005 as compared to 2004, primarily reflecting growth in unit sales and increased average sales price of single-use disposable devices of both the NovaSure System and MammoSite Radiation Therapy System. These increases also reflect the timing of Cytyc’s acquisitions of Proxima (March 7, 2005) and Novacept (March 24, 2004). Domestic net sales of Cytyc’s NovaSure System represented 85% and 86% of the domestic surgical products division’s net sales in 2006 and 2005, respectively, and net sales of the MammoSite Radiation Therapy System represented 14% and 12% of the domestic surgical products division’s net sales in 2006 and 2005, respectively. Cytyc’s 2005 operating results include the results of Proxima from the date of acquisition and Cytyc’s 2004 operating results include the results of Novacept from the date of acquisition.

Cytyc’s domestic diagnostic products net sales increased 7% in 2006 as compared to 2005 and 8% in 2005 as compared to 2004, due primarily to the continued increase in adoption and utilization of the ThinPrep Imaging System across Cytyc’s customer base.

Net sales in Cytyc’s international division, which is comprised of sales to customers outside the United States of both diagnostic and surgical products, increased 29% in 2006 as compared to 2005 and 28% in 2005 as compared to 2004. The increase in each year primarily reflects higher unit sales of the ThinPrep Pap Test and the NovaSure single-use disposable devices.

For the year ended December 31, 2006, no customer represented 10% or more of Cytyc’s consolidated net sales. Net sales to one customer within its domestic diagnostic division represented 11% and 17% of Cytyc’s consolidated net sales in 2005 and 2004, respectively.

Gross Margin

Cytyc’s gross margin was 78% in 2006 and was 79% in 2005 and 2004. The gross margin decreased during 2006, in part reflecting the inclusion of $1.3 million of stock-based compensation expense within cost of sales. Apart from this impact, gross margin reflected product mix, with increased placements of the ThinPrep Imaging System and growth in international sales of Cytyc’s diagnostic products, both of which generally have lower profit margins than sales of Cytyc’s disposable devices in the United States. The gross margin remained consistent in 2005 as compared to 2004, as the impact of domestic net sales of the ThinPrep Pap Test and increasing sales of the higher-margin NovaSure and MammoSite disposable devices were offset by increased placements of the ThinPrep Imaging System and growth in international sales of Cytyc’s diagnostic products, both of which generally have lower profit margins.

Operating Expenses

Total operating expenses increased to $272.4 million for 2006, an increase of 26% over 2005, as compared to an increase of 22% in 2005 over 2004. Operating expenses in 2006 include $19.9 million of stock-based compensation expense pursuant to the provisions of SFAS No. 123R. As a result of the adoption of SFAS No. 123R on January 1, 2006, as required, Cytyc began to recognize all stock-based compensation to employees, including grants of employee stock options, in the financial statements based on their fair values. Operating expenses in 2006 also include a restructuring charge of $2.9 million relating to Cytyc’s decision to consolidate its Mountain View, California operations into Cytyc’s existing operations in Costa Rica and Massachusetts. Operating expenses in 2005 include a $7.8 million charge as a result of an arbitration decision (see Note 10(e) to Cytyc’s audited consolidated financial statements), and Cytyc’s operating expenses in 2004 include a charge of $19.1 million to write off acquired in-process research and development costs related to its acquisition of Novacept in March 2004. The following is a summary of operating expenses for the years ended December 31, 2006, 2005 and 2004:

Research and Development

Cytyc’s core research and development strategy is to enhance its existing product lines, such as the ThinPrep Imaging System, the NovaSure System, the MammoSite Radiation Therapy System and the GliaSite Radiation Therapy System, through operational enhancements and cost reductions, as well as to continue to develop additional innovative medical diagnostic and surgical devices and therapeutic applications for cancer and women’s health, through Cytyc’s existing intellectual property as well as the acquisition of new intellectual property. Cytyc’s research and development costs increased to $44.1 million in 2006, an increase of $11.8 million or 37%, over 2005, as compared to an increase of $11.5 million or 55% in 2005 over 2004, primarily reflecting: (i) $3.0 million of stock-based compensation expense recorded in 2006 pursuant to SFAS No. 123R;

B-38

##### Table of Contents

(ii) $4.1 million and $3.7 million of incremental non-cash amortization of Cytyc’s developed technology intangible assets during 2006 and 2005, respectively, specifically resulting from Cytyc’s acquisitions of Novacept in March 2004 and Proxima in March 2005, which are amortized using the cash flow method; (iii) incremental expenses supporting the MammoSite Radiation Therapy System which were included in Cytyc’s operating results for the full year of 2006 as compared to slightly more than nine months in 2005 and none in 2004; and (iv) increased engineering costs and clinical trial costs to continue to improve the NovaSure System and the MammoSite Radiation Therapy System and to develop related technologies to grow Cytyc’s product lines, as well as incremental clinical trial costs in support of the FirstCyte Breast Test.

In-Process Research and Development

As part of the allocation of the purchase price of Novacept in March 2004, all intangible assets were identified and valued. It was determined that certain developed and in-development technology had value. As a result of this identification and valuation process, Cytyc allocated $19.1 million of the purchase price to in-process research and development projects in 2004. This allocation represents the estimated fair value based on risk-adjusted cash flows related to incomplete research and development activities associated with an upgrade to the RF Controller. The RF Controller delivers radio frequency energy and is one of the two primary components of the NovaSure System. The upgrade to the RF Controller was necessary to replace the existing power supply, a critical component of the RF Controller which was being discontinued by its supplier.

The rate utilized to discount the net cash flows to their present value was based on estimated weighted-average cost of capital calculations. A discount rate of 20% was used to value the in-process research and development project. This discount rate was higher than Cytyc’s weighted-average cost of capital due to the early-stage life cycle of the acquired products, the inherent uncertainties surrounding the outcome of the upgrade project and successful commercialization and development of the acquired assets, the useful life of the acquired technology, the profitability levels of such technology and the uncertainty of technological advances that were unknown at that time.

As of the date of acquisition (March 24, 2004), the upgrade to the RF Controller was under design review, the remaining costs to complete the project were not material and the project was anticipated to be, and actually was, completed in late 2004 with net cash inflows commencing at that time. Accordingly, the acquired in-process research and development was charged to expense as of the date of the acquisition. There have been no variations from Cytyc’s underlying projections and assumptions as compared to actual operating results that would have had a material impact on the valuation of the in-process research and development. In addition, since that time, there have been no additional significant, ongoing activities associated with the in-process research and development and there were no other significant acquired projects. There were no in-process research and development charges in connection with Cytyc’s acquisition of Proxima in March 2005.

Sales and Marketing

Sales and marketing costs increased to $161.9 million for the year ended December 31, 2006, an increase of $30.6 million or 23% over 2005, as compared to a 29% increase in 2005 over 2004, primarily due to incremental sales and marketing costs of Cytyc’s domestic surgical products division. These costs reflect: (i) $9.3 million of stock-based compensation expense during the year ended December 31, 2006 pursuant to SFAS No. 123R; (ii) the continued growth in the sales force to support increased sales of Cytyc’s surgical products, including the expansion of its domestic sales force resulting from the acquisition of Proxima in March 2005; and (iii) customer training costs associated with increased sales of Cytyc’s surgical products to new customers. These incremental costs were slightly offset by a decrease in costs related to the integration and cross-training of Cytyc’s sales forces, as the majority of these costs were incurred during 2005 following the Proxima acquisition.

B-39

##### Table of Contents

The 29% increase to $131.4 million for the year ended December 31, 2005 over 2004, was primarily due to sales and marketing costs at Cytyc’s domestic surgical products division. The increase of approximately $29.4 million in 2005 reflects the expansion of Cytyc’s domestic sales force resulting from the acquisitions of Novacept and Proxima in March 2004 and 2005, respectively, costs to integrate and cross-train Cytyc’s sales forces following the Proxima acquisition and costs associated with a direct-to-consumer marketing program launched during 2005 for Cytyc’s NovaSure product. In addition, Cytyc incurred incremental sales and marketing costs of approximately $3.4 million in 2005 as compared to 2004 to support its international expansion efforts.

Overall, Cytyc’s sales and marketing expense increased to 27% of net sales in 2006 as compared to 26% in both 2005 and 2004.

General and Administrative

General and administrative costs increased to $63.5 million for the year ended December 31, 2006, an increase of $18.2 million or 40% over 2005 and such costs increased 28% to $45.3 million for the year ended December 31, 2005 over 2004, primarily due to: (i) $7.6 million of stock-based compensation expense during the year ended December 31, 2006, pursuant to SFAS No. 123R; (ii) $3.6 million of costs associated with the acquisition and sale of shares of Vision Systems Limited; and (iii) increased costs during 2006 and 2005 to support the growth of Cytyc’s business, such as increases in personnel and facility costs, enhancements to Cytyc’s management information systems and increases in its product liability insurance coverage. The increases in general and administrative costs during 2006 were offset in part by a decrease in costs associated with litigation as compared to 2005 (See Note 10(e) to Cytyc’s audited consolidated financial statements).

As a percentage of net sales, general and administrative expenses were 10% in 2006 and 9% in both 2005 and 2004.

Restructuring

During the fourth quarter of 2006, Cytyc’s management approved a restructuring plan designed to reduce future operating expenses, by consolidating Cytyc’s Mountain View, California operations into its existing operations in Costa Rica and Massachusetts. In connection with this plan, Cytyc incurred $2.9 million of restructuring costs during the fourth quarter of 2006 related to severance expenses and expects to incur additional restructuring costs in 2007 of approximately $5 million to $6 million, primarily resulting from retention costs and incremental depreciation of leasehold improvements. None of the severance has been paid as of December 31, 2006 and all is expected to be paid during 2007.

Other Income (Expense), net

As a result of the sale of Cytyc’s shares of Vision Systems Limited in December 2006, Cytyc realized a gain of $11.2 million and included this gain within gain on strategic investments, net in its consolidated statement of income. In addition Cytyc recorded a realized foreign currency gain of $1.9 million related to this transaction and included such gain in other income (expense).

Cytyc recorded interest expense of $7.5 million, $7.2 million, and $5.4 million for the years ended December 31, 2006, 2005, and 2004, respectively, related primarily to its 2.25% convertible notes due 2024, which were issued on March 22, 2004, including amortization of $1.7 million, $1.5 million, and $1.2 million, respectively, of deferred financing costs, primarily associated with the issuance of these notes. Interest income increased to $7.2 million, $3.3 million, and $2.4 million in each of the years ended December 31, 2006, 2005 and 2004, respectively, as the average interest rate for Cytyc’s cash, cash equivalents and investment securities was higher in each year as compared to the immediately preceding year.

Income Taxes

During the year ended December 31, 2006, Cytyc completed tax audits that resulted in the recognition of a tax benefit in its consolidated statement of income of approximately $2 million and a decrease in its effective tax rate for 2006 to 35%. Cytyc’s effective tax rates for 2005 and 2004 were 36.5% and 43.6%, respectively. Exclusive of the effects of the non-deductible $19.1 million in-process research and development charge incurred in connection with the Novacept acquisition in March 2004, Cytyc’s effective tax rate for 2004 would have been 38%. The decrease from 2005 to 2006 was due to the completion of various tax audits and an increase in tax-exempt interest income. The decrease from 2004 to 2005 was due to savings from tax planning initiatives which began in 2003, as well as the impact in 2005 of the American Jobs Creation Act of 2004. Cytyc is undergoing various audits on the state level and expects these audits to conclude at various dates throughout 2007. Although Cytyc believes it has adequate reserves for potential assessments, Cytyc recognizes liabilities for potential tax audit issues in the United States and other tax jurisdictions based on its estimate of whether, and to the extent to which, additional taxes will be due. If Cytyc ultimately determines that these reserves are greater or less than the amounts paid, Cytyc will adjust the reserves and recognize a tax benefit or charge during the period in which it makes the determination or, if the adjustments to the reserves relate to deferred tax assets recorded in connection with an acquisition, Cytyc will adjust the carrying value of goodwill. Cytyc estimates that its effective tax rate for 2007 will be in the range of 35% to 35.5% as Cytyc continues to realize savings from tax planning initiatives, as well as the impact of the American Jobs Creation Act of 2004.

Liquidity and Capital Resources

At March 31, 2007, Cytyc had cash, cash equivalents and investment securities totaling $196.3 million. Cash provided by operations was $56.6 million for the three months ended March 31, 2007, an increase of 38% compared to $41.2 million during the same period of 2006, primarily as a result of increased net sales as compared to the same period in the prior year and Cytyc’s $11.4 million payment to DEKA during the first quarter of 2006 relating to the arbitration panel decision. Cytyc’s net accounts receivable increased 16% to $110.3 million at March 31, 2007 as compared to $94.9 million at December 31, 2006, reflecting continued growth in net sales, as well as the timing of cash collections. Cytyc’s Days Sales Outstanding (“DSO”) was 58 and 52 days at March 31, 2007 and December 31, 2006, respectively. Cytyc has had no significant issues of collectibility. The increase in DSO is largely the result of Cytyc’s acquisition of Adeza during March 2007, which has generally had a higher DSO than Cytyc’s historical average. The term “Days Sales Outstanding”, which Cytyc calculates by dividing gross trade accounts receivable at the end of the quarter by its average consolidated daily net sales for the quarter, refers to the estimated number of days’ worth of sales that are outstanding and unpaid at any given time. Cytyc’s inventories increased 10% to $32.4 million at March 31, 2007 as compared to $29.5 million at December 31, 2006, primarily reflecting an increase in inventory to support the growth in net sales in Cytyc’s domestic surgical products business, with a small incremental increase as a result of Cytyc’s acquisition of Adeza.

At December 31, 2006, Cytyc had cash, cash equivalents and investment securities totaling $297.7 million. Cash provided by operations was $173.7 million for 2006, a decrease of 1%, as compared to cash from operations of $176.0 million in 2005, primarily as a result of Cytyc’s $11.4 million payment to DEKA during the first quarter of 2006 relating to the arbitration panel decision (see Note 10(e) to Cytyc’s audited consolidated financial statements), partially offset by increased net sales and timing of cash collections as compared to the prior year. Cash provided by operations in 2005 increased 28% as compared to cash from operations of $137.6 million in 2004, primarily as a result of increased net sales and the utilization of favorable tax attributes included in the Novacept and Proxima acquisitions. Cytyc’s net accounts receivable increased 15% to $94.9 million at December 31, 2006, as compared to $82.8 million at December 31, 2005, reflecting continued growth in net sales, as well as the timing of cash collections. DSO improved to 52 days at December 31, 2006 as compared to 53 days at December 31, 2005. Cytyc’s inventories increased 23% to $29.5 million at December 31, 2006, as compared to $24.0 million at December 31, 2005, primarily reflecting an increase in inventory to support growth in net sales across its business.

##### Table of Contents

Cytyc’s investing activities used cash of $269.1 million during the three months ended March 31, 2007, primarily related to the acquisitions of Adeza and Adiana in March 2007. The total purchase prices for Adeza and Adiana were $456.7 million and $60.5 million (excluding contingent payments), respectively, including acquisition-related costs (see Note 2 to Cytyc’s condensed consolidated financial statements). During the first quarter of 2007, Cytyc paid $365.0 million and $58.1 million, respectively (net of cash acquired), related to these acquisitions using a combination of cash on hand and borrowings on its line of credit. As of March 31, 2007, Cytyc had an additional $66.4 million accrued relating to these acquisitions, most of which was paid during April 2007. Also during the three months ended March 31, 2007: Cytyc (i) paid $3.6 million to the former stockholders of Proxima Therapeutics, Inc. (“Proxima”), a company Cytyc acquired in 2005, for contingent earn-out payments relating to incremental sales growth in Cytyc’s breast-related products during 2006 (there will be no further contingent earn-out payments associated with the Proxima acquisition); (ii) invested $5.2 million in equipment under customer usage agreements, of which $4.6 million represented ThinPrep Imaging System units; and (iii) made $3.5 million of capital expenditures during the three months ended March 31, 2007, related primarily to Cytyc’s investment in manufacturing processes and information systems to support the growth of its business. During 2007, Cytyc expects to invest between $45 million and $50 million for the manufacture of equipment to be placed at customer sites and capital expenditures, including an investment in systems and infrastructure improvements and other machinery and equipment purchases to support the growth in its business.

During the three months ended March 31, 2006, Cytyc’s investing activities used cash of $36.7 million, primarily related to the payment of $21.1 million to the former Proxima shareholders for the contingent earn-out payments relating to incremental sales growth in Cytyc’s breast-related products during 2005 pursuant to the terms of the related merger agreement. In addition, during the three months ended March 31, 2006, Cytyc invested $7.3 million in equipment under customer usage agreements, of which $6.4 million represented ThinPrep Imaging System units, and Cytyc made $4.1 million of capital expenditures.

Cytyc’s investing activities used cash of $120.6 million in 2006, primarily as a result of: (i) the March 2006 payment of $21.1 million to the former Proxima stockholders for the contingent earn-out payments relating to incremental sales growth in Cytyc’s breast-related products during 2005 (see Note 4(b) to Cytyc’s audited consolidated financial statements); (ii) Cytyc’s investment of $25.5 million in equipment under customer usage agreements, of which approximately $21.0 million represented ThinPrep Imaging Systems units; (iii) $22.3 million of capital expenditures during 2006, related primarily to Cytyc’s investment in manufacturing processes and information systems to support the growth of its business; and (iv) $48.5 million net purchases of investment securities, including proceeds of $11.2 million from the sale of Cytyc’s shares of Vision Systems Limited in December 2006 (see Note 4(d) to Cytyc’s audited consolidated financial statements).

Cytyc’s investing activities used cash of $152.4 million in 2005, primarily related to the purchase of Proxima in March 2005, partially offset by net proceeds from sales and maturities of investment securities. As of December 31, 2005, Cytyc paid $163.0 million of the Proxima purchase price using a combination of cash, cash equivalents and investment securities to fund the purchase. During 2005, Cytyc also invested $27.3 million in equipment used under customer usage agreements, of which approximately $22.0 million represented ThinPrep Imaging Systems for use at customer sites. Cytyc also made $13.4 million of capital expenditures during 2005, related primarily to its investment in manufacturing processes, facilities and information systems to support the growth of its business, as well as costs to manufacture the ThinPrep Imaging System units to be placed at customer sites under usage agreements.

Cytyc’s financing activities during the three months ended March 31, 2007 provided cash of $204.9 million, primarily reflecting its borrowings of $200.5 million on its line of credit facility to facilitate its purchases of Adeza and Adiana, as well as $20.9 million of proceeds and tax benefits from the exercise of stock options. Partially offsetting these cash inflows was the repurchase of $16.5 million of Cytyc common stock during the three months ended March 31, 2007 as part of Cytyc’s stock repurchase program. Cytyc’s financing activities during the three months ended March 31, 2006 used cash of $5.6 million, primarily reflecting Cytyc’s repurchase of $22.3 million of its common stock as part of Cytyc’s stock repurchase program, partially offset by proceeds and tax benefits from the exercise of stock options of $16.6 million.

B-42

##### Table of Contents

Cytyc’s financing activities in 2006 used cash of $36.7 million, primarily reflecting its repurchase of $108.6 million of Cytyc common stock as part of its stock repurchase program, partially offset by proceeds of $65.8 million and $3.8 million from the exercise of stock options and employee purchases of Cytyc common stock under the employee stock purchase plan, respectively. Cytyc’s financing activities in 2005 generated cash of $14.0 million, resulting from proceeds of $61.1 million and $2.9 million from the exercise of stock options and employee purchases of Cytyc common stock under the employee stock purchase plan, respectively, partially offset by its repurchase of $50.1 million of Cytyc common stock, including $0.1 million in commissions, as part of its stock repurchase program.

Long-Term Debt and Contractual Obligations

Convertible Notes—On March 22, 2004, Cytyc completed the sale (the “Offering”) of $250 million aggregate principal amount of its 2.25% convertible notes due 2024. The convertible notes were sold to qualified institutional buyers pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended. The notes bear interest at a rate of 2.25% per year on the principal amount, payable semi-annually in arrears in cash on March 15 and September 15 of each year, beginning September 15, 2004. The holders of the notes may convert the notes into shares of Cytyc’s common stock at a conversion price of $29.67 per share, subject to adjustment, prior to the close of business on March 15, 2024, subject to prior redemption or repurchase of the notes, under any of the following circumstances: (1) during any calendar quarter commencing after June 30, 2004 if the closing sale price of Cytyc’s common stock exceeds 120% of the conversion price for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter (if the specified threshold is met, the notes will thereafter be convertible at any time at the option of the holder prior to the close of business on March 15, 2024); (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each day of such period was less than 98% of the product of the closing sale price of Cytyc’s common stock and the number of shares issuable upon conversion of $1,000 principal amount of the notes; (3) if the notes have been called for redemption; or (4) upon the occurrence of specified corporate events.

Holders may require Cytyc to repurchase the notes on March 15 of 2009, 2014 and 2019 at a repurchase price equal to 100% of their principal amount, plus accrued and unpaid interest, including contingent interest and liquidated damages, if any, to, but excluding, the repurchase date. Cytyc may redeem any of the notes beginning March 20, 2009, by giving holders at least 30 days’ notice.

Credit Agreement—Cytyc has a five-year Credit Agreement (the “Credit Agreement”) with a syndicate of lenders, which provides for a $345 million senior unsecured revolving credit facility. Cytyc may request an increase in available borrowings under the Credit Agreement by an additional amount of up to $155 million (for a maximum amount of $500 million) upon satisfaction of certain conditions. The loan proceeds are available to be used by Cytyc and its subsidiaries to finance working capital needs and for general corporate purposes, including future business acquisitions, as defined. Four of Cytyc’s wholly-owned subsidiaries are guarantors under the Credit Agreement. On May 14, 2007, Cytyc and its related lenders amended the Credit Agreement in order to: (i) extend to July 31, 2007 the delivery deadline for both the audited financial statements for the fiscal year ended December 31, 2006 and the unaudited financial statements for the fiscal quarter ended March 31, 2007; and (ii) amend the negative covenant concerning Indebtedness (as such term is defined in the Credit Agreement) to increase the maximum size of the receivables financing facility permitted thereunder from $50 million to $100 million.

Amounts under the Credit Agreement may be borrowed, repaid and re-borrowed by Cytyc from time to time until the maturity of the Credit Agreement on June 30, 2011. Voluntary prepayments and commitment reductions requested by Cytyc under the Credit Agreement are permitted at any time without penalty (other than customary breakage costs relating to the prepayment of any drawn loans) upon proper notice and subject to a minimum dollar requirement. Borrowings under the Credit Agreement bear interest at a floating rate, which will be, at Cytyc’s option, either LIBOR plus an applicable margin (which is subject to adjustment based on financial ratios), or a base rate.

The Credit Agreement requires Cytyc to comply with maximum leverage and minimum fixed charge coverage ratios. The Credit Agreement contains affirmative and negative covenants, including limitations on additional debt, liens, certain investments, and acquisitions outside of the healthcare business. The Credit Agreement also includes events of default customary for facilities of this type. Upon the occurrence of an event of default, all outstanding loans may be accelerated and/or the lenders’ commitments terminated.

As of March 31, 2007, Cytyc had $200.5 million outstanding under this Credit Agreement at an interest rate of 5.32% (LIBOR) plus a margin of 0.475% providing a total interest rate of 5.795%, of which $80.3 million was repaid in April 2007.

Adiana Earn-out Payments—Part of the purchase price for Adiana includes contingent earn-out payments tied to future performance milestones see (Note 2(b) to Cytyc’s consolidated financial statements).

Contractual Obligations—Cytyc’s future contractual cash obligations as of March 31, 2007 are as follows (in thousands):

|  | Payments Due by Period

(2) | Primarily relates to the remainder of Cytyc’s $5 million private equity investment commitment.

(3) | The line of credit borrowings bear a variable interest rate as such interest payments are not included in this table. Cytyc has included this amount in current liabilities in its condensed consolidated balance sheet as Cytyc expects to repay this amount within one year.

(4) | Relates to Cytyc’s $250 million aggregate principal amount of 2.25% convertible senior notes described above. The amounts in the table above include interest and principal payable assuming redemption at the earliest redemption date of March 5, 2009. These amounts assume that conversion of the notes into shares of Cytyc common stock does not occur.

(5) | Cytyc has not included $5.3 million of liabilities relating to uncertain tax positions within this schedule due to uncertainty of the payment date, if any.

Cytyc expects that its cash and cash equivalents, investment securities, cash flows from operating activities and funds available under its Credit Agreement will be sufficient to meet its projected operating cash needs for the next twelve months, including capital expenditures, lease and purchase commitments and tax payments. However, from time to time, Cytyc reviews its capital structure and financing arrangements. As a result of these reviews, Cytyc may periodically elect to pursue alternatives to its current structure, including the refinancing of

its existing debt securities, the issuance of additional debt securities, the expansion of the existing credit facility, and the emplacement of an additional credit facility. In addition, if Cytyc makes future acquisitions, it may be required to seek additional capital.

Off-Balance Sheet Arrangements

Cytyc does not maintain any off-balance sheet financing arrangements apart from the operating leases described above.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. Among other requirements, SFAS No. 157 defines fair value and establishes a framework for measuring fair value and also expands disclosure requirements regarding fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those years. Cytyc is currently evaluating the potential impact that adopting SFAS No. 157 will have on Cytyc’s consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115, which permits entities to measure various financial instruments and certain other items at fair value at specified election dates. The election must be made at initial recognition of the financial instrument, and any unrealized gains or losses must be reported at each reporting date. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Cytyc is currently evaluating the potential impact that adopting SFAS No. 159 will have on Cytyc’s consolidated financial statements.

Quantitative and Qualitative Disclosures About Market Risk

Derivative Financial Instruments, Other Financial Instruments, and Derivative Commodity Instruments

At March 31, 2007, Cytyc was not a party to any derivative financial instruments, other financial instruments for which the fair value disclosure would be required under SFAS No. 107, Disclosures about Fair Value of Financial Instruments, or derivative commodity instruments. At March 31, 2007, all of Cytyc’s investments were in municipal bonds and commercial paper that are carried at fair value on Cytyc’s books. Accordingly, Cytyc has no quantitative information concerning the market risk of participating in such investments.

Primary Market Risk Exposures

Cytyc’s primary market risk exposures are in the areas of interest rate risk and foreign currency exchange rate risk. Cytyc’s investment portfolio of cash equivalents and investment securities is subject to interest rate fluctuations, but Cytyc believes this risk is immaterial due to the short-term nature of these investments. Cytyc’s business outside the United States is conducted primarily in local currencies, except in Costa Rica, where the majority of business is conducted in the U.S. dollar. Cytyc has no foreign exchange contracts, option contracts, or other foreign hedging arrangements. Cytyc estimates that any market risk associated with its international operations is unlikely to have a material adverse effect on Cytyc’s business, financial condition or results of operations.

Interest Rate Risk and Management

As of March 31, 2007, Cytyc’s debt portfolio included both a fixed rate instrument ($250 million) and a floating rate instrument (approximately $200.5 million). The weighted average interest rate during the three

B-45

##### Table of Contents

months ended March 31, 2007 of the fixed instrument portfolio was 2.25% and the weighted average interest rate during the three months ended March 31, 2007 for the variable instrument portfolio was approximately 5.80%. While Cytyc’s fixed rate instrument guarantees that the impact on Cytyc’s consolidated statements of (loss) income and cash flows will be predictable, changes in interest rates can cause the value of Cytyc’s fixed rate debt to change. However, such a value change has no impact on either Cytyc’s consolidated statements of (loss) income or cash flows unless Cytyc determines that it wishes to retire a fixed rate debt obligation on the open market.

Alternatively, Cytyc’s future consolidated statements of (loss) income and future cash flows can fluctuate with its floating rate borrowings. However, the impact would be partially mitigated by the floating rate interest earned on excess cash. If there were a hypothetical 10% change in interest rates, the net impact to Cytyc’s consolidated statements of (loss) income and cash flows would be approximately $0.1 million. The potential change in cash flows and earnings is calculated based on the change in the net interest expense over one quarter due to an immediate 10% change in rates.

CYTYC EXECUTIVE AND DIRECTOR COMPENSATION

Compensation Discussion & Analysis

This discussion should be read in conjunction with the tables and related discussion beginning on page B-57 of this joint proxy statement/prospectus.

Introduction

Cytyc’s executive compensation program is designed to attract, retain and motivate high-performing leaders to achieve strong business results and enhance stockholder value. To this end, Cytyc’s executive compensation program is strongly linked to the delivery of long-term returns to its stockholders, the achievement of short- and long-term strategic business objectives, individual performance, and the demonstration of competencies that are aligned with its values.

The compensation committee uses its business judgment to establish Cytyc’s executive compensation philosophy and policies, and oversees the implementation of Cytyc’s executive compensation programs, drawing on internal and external resources to provide necessary information and recommendations, as appropriate.

Executive Compensation Objectives and Considerations

The fundamental objective of Cytyc’s executive compensation program is to support the creation of long-term stockholder value. The executive officers named in the “—Summary Compensation Table” on page B-57 of this joint proxy statement/prospectus (“named executive officers” or “NEOs”) and other executive officers are critically important to Cytyc’s ability to create stockholder value. It is in the stockholders’ interests that the compensation of Cytyc’s executive officers be structured in a manner which encourages the efforts of Cytyc’s executive officers which will enable Cytyc to reach desired objectives. Cytyc believes that it is in the best interest of the company, its stockholders and Cytyc’s other important non-stockholder constituencies to employ highly-talented, able, high-performing leaders who are able to sustain and improve upon Cytyc’s strong performance.

In order to achieve this fundamental objective, Cytyc believes that it is appropriate to focus primarily on each executive officer’s total compensation opportunity, reviewed annually on a prospective basis, and that a significant portion of each executive officer’s total compensation opportunity should be performance-based, reflecting both upside potential and downside risk. In addition, as a means of ensuring that the interests of Cytyc’s executive officers are aligned with those of its stockholders, Cytyc believes that executive officers should build and maintain an equity interest in the company. To this end, Cytyc pays these officers a meaningful portion of their compensation in equity, and, in March 2007, adopted revised stock ownership guidelines for Cytyc’s executive and other officers.

General Considerations

Executive compensation, particularly incentive-based compensation, is material to the company because Cytyc believes it has a strong impact on the performance of its executive officers. The actions of Cytyc’s executive officers, both individually and as a group, are extremely important in shaping business outcomes in both the short- and the long-term. Therefore, it is important to strike a balance between rewarding short-term financial results while also rewarding actions that will lead to desired business results over a period of several years.

| • |  | It is Cytyc’s objective to have a portion of each executive officer’s compensation contingent upon the achievement of specific pre-determined corporate objectives, as well as upon each executive officer’s individual level of performance.

B-48

##### Table of Contents

| • |  | The impact of the NEOs and other executive officers is not merely on matters that can be readily measured (e.g., financial performance indicators), but also on other important, subjective variables, including culture and values. Consequently, a focus on objective indicators, while important, must be balanced by other, broader considerations which impact Cytyc’s business.

| • |  | No system can be perfect, and every executive compensation system, if rigidly applied, can have unintended consequences. Judgment in application is therefore important.

| • |  | Proven, capable senior leaders who know the company, have industry knowledge, operational experience, and a track record of success are extremely valuable. Such individuals are commercially sophisticated, informed, attractive to competitors and have many other opportunities available to them, both in public companies and in other sectors of the economy. The cost of locating or developing alternative executives, whether internally or through external recruiting, is high.

| • |  | The success of a complex organization such as the company is critically dependent upon effective teamwork at the executive officer level, as well as on individual capability.

| • |  | Individuals vary in the value they attach to specific elements of compensation, but in general, the highest value is attributable to immediately available compensation. Cytyc seeks to balance the value of each element of compensation to the company against the perceived value of such element to the executive officer.

| • |  | Individuals generally prefer a clear understanding of the factors that determine compensation, but a strictly formulaic approach can lead to undesired behaviors. Cytyc seeks to provide a high degree of clarity, ensuring that executive officers are focused on the key drivers of success, while also retaining a degree of discretion to recognize particular circumstances.

Major decisions affecting the long-term future of Cytyc’s business are a constant part of decision-making. It is difficult in the short-term to measure the precise impact that good and bad decisions in these areas will have on long-term prospects. As a result, Cytyc’s choice of performance objectives, as well as the specific values of the targeted objectives, are affected by the current and future needs of the business and may change from year-to-year. Cytyc seeks to encourage executive officers to make decisions that are designed to support long-term value creation balanced against the need to also deliver short-term results.

Compensation Consultant

From July 2004 through June 2006, Towers Perrin served as the compensation committee’s independent compensation consultant. In setting executive total compensation levels for 2006, the compensation committee utilized Towers Perrin as its executive compensation consultant. Towers Perrin provided data on executive compensation market trends and levels that were used to establish executive compensation for Cytyc’s NEOs.

In October 2006, the compensation committee engaged FW Cook as its independent compensation consultant and asked them to perform a comprehensive review of Cytyc’s approach to and delivery of executive compensation. The results of the study were used in refining Cytyc’s compensation strategy and setting executive officer compensation for 2007.

Committee Activity

Following FW Cook’s review of Cytyc’s executive compensation strategy, the compensation committee, in early 2007, approved the recommendations set forth by FW Cook. As a result, and among other considerations, the compensation committee decided to:

| • |  | Update the peer group of companies (the peer groups for both 2006 and 2007 appear below under “—Competitive Considerations”) with respect to which executive compensation comparisons would be made, to more closely align the company with its market contemporaries;

B-49

##### Table of Contents

| • |  | Modify the definition of financial metrics employed in the performance-based cash incentive program;

| • |  | Change the form of long-term equity awards from all options to a combination of options and performance shares (performance shares to be earned based upon achievement of certain performance measures over a three-year period);

| • |  | Eliminate Cytyc’s supplemental executive health-care benefit effective January 1, 2007 for Cytyc executive officers, and effective January 1, 2008 for all vice presidents who are not executive officers; and

| • |  | Adopt and implement the revised executive stock ownership guidelines.

Competitive Considerations

Determination by the Compensation Committee—Cytyc believes that it is critical to its long-term performance to offer its executive officers compensation opportunities that are broadly commensurate with their competitive alternatives. However, competitive alternatives vary from individual to individual and may extend beyond equivalent positions in Cytyc’s industry or at other publicly traded or similarly situated companies. As a result, the compensation committee sets each executive officer’s total compensation opportunity and each compensation element based primarily on a series of both subjective and objective factors, such as (i) Cytyc’s past performance and expectations of future performance, (ii) individual scope of responsibility, performance and experience, (ii) the executive compensation reports of independent consultants engaged by the compensation committee and (iv) past compensation levels.

Market Comparisons and Peer Group Selection—Cytyc obtains market comparison information from analyses of publicly-available information for a peer group comprised of companies from the medical device and diagnostics industry as well as and the pharmaceutical industry. The compensation committee selects the companies to be included in the peer group from the medical device, diagnostic and pharmaceutical companies because Cytyc’s business model takes into account certain aspects of these three life science sector markets, and employment opportunities for Cytyc’s executives as well as the talent pool from which Cytyc recruits, stem from similar companies. The peer companies are chosen based on their relative annual revenue, revenue growth, size, and relevance to Cytyc’s mix of businesses. They are generally publicly-traded companies of similar size and scope to Cytyc, and share some or all of the following characteristics with Cytyc: requisite skill bases, competitive intensity, degree of regulation and operating requirements. For 2006, the compensation committee approved the following peer group, which was chosen with the assistance of Towers Perrin:

Medical Devices & Diagnostic Companies: |  | Pharmaceutical Companies:
Affymetrix, Inc. Arrow International, Inc. Advanced Medical Optics, Inc. The Cooper Companies, Inc. Diagnostics Produce Corporation Gen-Probe Incorporated Haemonetics Corporation IDEXX Laboratories, Inc. Mentor Corporation Respironics, Inc. ResMed, Inc. Waters Corporation |  | American Pharmaceuticals Partners, Inc Cephalon, Inc. Gilead Sciences, Inc. K-V Pharmaceutical Company Medicis Pharmaceutical Corporation Millennium Pharmaceuticals, Inc. Par Pharmaceutical Companies, Inc. Sepracor, Inc.

With the assistance of FW Cook, the compensation committee revised the peer group peer group effective for 2007 by removing three medical devices and diagnostic companies (Diagnostics Produce Corporation, IDEXX Laboratories, Inc. and Mentor Corporation) and adding four new companies (Bio-Rad Laboratories, Inc.,

B-50

##### Table of Contents

Conmed Corp., Hologic Inc and Millipore Corp.), and by removing three pharmaceuticals companies (American Pharmaceuticals Partners, Inc., Gilead Sciences, Inc. and Par Pharmaceutical Companies, Inc.) and adding Abraxis Bioscience Inc. The updated peer group effective for 2007 consists of:

Medical Devices & Diagnostic Companies: |  | Pharmaceutical Companies:
Affymetrix, Inc. Arrow International, Inc. Advanced Medical Optics, Inc. Bio-Rad Laboratories Inc Conmed Corp The Cooper Companies, Inc. Gen-Probe Incorporated Haemonetics Corporation Hologic Inc Millipore Corp Respironics, Inc. ResMed, Inc. Waters Corporation |  | Abraxis Bioscience Inc Cephalon, Inc. K-V Pharmaceutical Company Medicis Pharmaceutical Corporation Millennium Pharmaceuticals, Inc. Sepracor, Inc.

In light of Cytyc’s practice of making a relatively high portion of each executive officer’s compensation based on performance (i.e., at risk) as compared to its peers, and because most of Cytyc’s performance targets are set at the top quartile or higher (as compared to the performance of Cytyc’s peers on the targeted factors), the compensation committee generally examines peer company data at the 50 th and 75 th percentiles for the peer companies. The opportunity for compensation for NEO and other executive officers is generally available at the 75 th percentile of peer practice in order to encourage performance that is equal to top quartile or higher performance among comparable peers and reasonably aligned with Cytyc’s strategic plan.

Elements of Executive Compensation

Focus on Total Compensation Opportunity—Cytyc’s annual executive compensation decisions begin with a determination of the appropriate total compensation opportunity to be made available to each NEO. The compensation committee reviews the combined value of all of the elements of compensation, considering proposed compensation, actual compensation for the previous year, and the balance among the elements. Cytyc believes that a significant portion of each NEO’s total compensation opportunity should be performance-based, reflecting both upside potential and downside risk, and, generally, that the higher an executive’s level within Cytyc’s executive structure, the greater the proportion of total compensation which should be at risk. Each NEO’s annual total compensation opportunity is comprised of a mix of compensation elements, consisting of base salary, annual performance-based cash incentive, longer-term equity incentives and certain personal benefits. Cytyc expects that this mix can and should be revised from time-to-time as its needs and objectives, as well as industry and peer group practices, change.

Balance Among the Elements—When determining the proportion of total compensation that will be comprised of each compensation element, the compensation committee reviews current market practices and industry trends. Within the performance-based compensation category, the compensation committee seeks to focus the efforts of the NEOs on company goals related to increasing stockholder value. In addition, the compensation committee considers the NEOs’ perceived value of the various elements of compensation and seeks input from the Chief Executive Officer (but only with respect to compensation for other NEOs), as well as the advice of its independent compensation consultant, to assist in maximizing cost efficiency and motivational value.

B-51

##### Table of Contents

2006 Executive Compensation Components—For the fiscal year ended December 31, 2006, the principal components of compensation for the NEOs were:

| • |  | base salary;

| • |  | performance-based cash incentive compensation;

| • |  | long-term equity incentive compensation; and

| • |  | certain personal benefits.

Base Salary— Cytyc pays base salaries to compensate its executive officers for performing their basic responsibilities. Base salaries for each of Cytyc’s executive officers, including the Chief Executive Officer, are generally set within a range of salaries paid to executive officers at peer companies with comparable qualifications, experience, responsibilities and performance. In setting compensation levels, the compensation committee takes into account such factors as (i) Cytyc’s past performance and expectations of future performance; (ii) individual scope of responsibility, performance and experience; (iii) the reports of independent compensation consultants engaged by the compensation committee; (iv) past salary levels; and (v) the recommendations of the Chief Executive Officer, but only with respect to other NEOs. The compensation committee does not assign relative weights or rankings to these factors, but instead makes a determination based upon the consideration of all of these factors, as well as the progress made with respect to Cytyc’s long-term goals and strategies.

At its meeting in January 2006, the compensation committee considered base salary levels for the NEOs. Effective January 1, 2006, the compensation committee approved increases in NEO salaries as follows:

Name and Position |  | Annual Base Salary |  | Increase from Previous Year |
Patrick J. Sullivan Chairman, Chief Executive Officer and President |  | $ | 575,000 |  | 11.7 | %

Performance-Based Cash Incentive Compensation—

General. Cytyc’s 2006 Executive Incentive Plan (the “2006 Plan”) was intended to focus the NEO’s attention on shorter-term attainment of high levels of operating and financial performance. NEOs were eligible for annual cash incentive compensation under the 2006 Plan based primarily upon the level of achievement, both by the individual officer and the company, of performance targets established for each year, as well as on the compensation committee’s assessment of individual performance.

Cytyc’s annual incentive payments for NEOs are determined based on a combination of performance elements consisting of corporate financial objectives, corporate “stretch” goals and individual performance. “Baseline” incentive awards are determined by (i) corporate revenue and (ii) profit before interest and taxes, with each metric assigned equal weighting in order to support and balance the Company’s strategic focus on top-line and bottom-line growth .The “baseline” bonus targets range from 60% to 100% of base salary, depending on the NEO. An NEO can earn more than the target amount for superior performance. Corporate “stretch” goals, based

on certain incremental predetermined operational goals, provide an NEO with the opportunity to earn an additional 10% (in total) of “baseline” bonus. Individual goals (Mr. Sullivan has only company goals) serve to modify the “baseline” bonus earned by +/-20% (in total). All metrics were approved by the compensation committee to provide the balanced measurement of current external results to stockholders, efficient and effective internal decisions to generate future stockholder returns, and strategic and operational initiatives.

The maximum incentive payment under the 2006 Plan was 155% of the “baseline” bonus, consisting of (i) a maximum of 125% of “baseline” bonus based on the company’s financial performance; (ii) a maximum of 10% of “baseline” bonus based on the company’s achievement of corporate “stretch” goals and (iii) a maximum of 20% of “baseline bonus” based on individual performance.

The incentive awards were structured to comply with the “performance-based” compensation rules of Section 162(m) of the Internal Revenue Code of 1986 (“Section 162(m)”) to ensure the tax deductibility of compensation paid to NEOs. See “—Tax and Accounting Considerations” below.

Setting Performance Targets. The compensation committee set minimum, target and maximum levels for each component of the corporate financial objective portion of 2006 Plan. As a general principle, Cytyc believes that performance targets should be set at levels that reflect excellent performance, superior to the results of typical companies in Cytyc’s industry, but that the targets should be achievable—that is, significant, sustained creative effort on the part of the executive team should be required in order to attain the targets, while at the same time the targets should represent a reasonable expectation of performance, assuming the team delivers the effort. Target levels that are set too low may fail to result in the best performance attainable, while target levels that are set too high can fail to serve as motivation. To achieve this, target levels are set in such a way to encourage performance that is equal to top quartile or higher performance among comparable peers and reasonably aligned with Cytyc’s strategic plan. In making the annual determination of the minimum, target and maximum levels, the compensation committee considers: (i) the specific circumstances facing the company in the current year; (ii) financial objectives of Cytyc’s strategic plan; and (iii) stockholders’ expectations regarding the company performance. Over time, the compensation committee seeks to maintain this basic principle.

2006 Performance-Based Incentive Awards for the Named Executive Officers. For Mr. Sullivan, President and Chief Executive Officer, the compensation committee considered only the company’s performance to derive his final incentive award. For each of the other NEOs, individual performance related to each of their areas of responsibility was also considered. In years where the company’s performance is above or substantially above the performance of its peers, Cytyc expects that annual incentive awards will be paid to the NEOs at a rate exceeding the targeted rate. For 2006, the NEOs annual incentive awards were as follows:

Named Executive Officer |  | 2006 Base Salary |  | Incentive Target as % of Base Salary |  |  | Annual Incentive Achieved |  |  | 2006 Incentive Award
Patrick J. Sullivan |  | $ | 575,000 |  | 100 | % |  | 126.1 | % |  | $ | 725,000
Timothy M. Adams |  |  | 325,000 |  | 60 |  |  | 69.2 |  |  |  | 225,000
Daniel J. Levangie |  |  | 425,000 |  | 80 |  |  | 82.4 |  |  |  | 350,000
John P. McDonough |  |  | 325,000 |  | 60 |  |  | 66.2 |  |  |  | 215,000
A. Suzanne Meszner-Eltrich |  |  | 285,000 |  | 60 |  |  | 70.2 |  |  |  | 200,000

The amounts set forth above for the NEOs’ 2006 annual incentive awards are also set forth in the “Non-Equity Incentive Plan Compensation” column in the Summary Compensation Table on page B-57 of this joint proxy statement/prospectus.

While performance targets are established at levels that are intended to be achievable, a maximum bonus payout would require very high levels of both individual and company performance which Cytyc believes are possible to be achieved only with extraordinary effort. Generally, the compensation committee sets the target and maximum performance requirements such that relative difficulty of achievement is consistent from year to year.

Long-Term Equity Incentive Compensation—

General. The portion of the NEOs’ compensation comprised of equity-based compensation is designed to reward longer-term performance, retain executives and more closely align the interests of Cytyc’s executives with the interests of stockholders. Equity ownership by executive officers helps to balance the short-term focus of annual incentive compensation with a longer-term view and may help to retain executive talent. Cytyc has historically relied predominantly on stock options as the preferred form of long-term compensation. Cytyc believes that granting stock options is consistent with similarly high-growth oriented companies and competitive practices in that they reinforce long-term results and align Cytyc’s executives’ interests with those of its stockholders. However, in light of Cytyc’s evolving strategic goals, the stage of development of the Company, and the requirement for stock option expensing for financial statements beginning in 2006, Cytyc has decided to adjust the long-term incentive strategy for NEOs and other executives and grant both stock options and performance shares beginning in 2007.

The compensation committee generally grants options that become exercisable over a four- to five-year period as a means of encouraging executive officers to remain with Cytyc and promote its long term success. The compensation committee awards options with exercise prices equal to the closing market price of the common stock on the date of grant. As a result, executive officers will benefit from these stock option grants only to the extent that the price of Cytyc common stock increases and Cytyc stockholders have also benefited.

2006 Long Term Equity Incentive Compensation Awards for the Named Executive Officers. Stock options are granted to the NEOs and other executives early in each calendar year on the date of the compensation committee meeting that is set the previous year to review Cytyc’s performance in the prior year (the 2006 meeting held on January 24, 2006 was scheduled on February 9, 2005). The exercise price of options granted is equal to the closing market price of Cytyc’s common stock on the date of grant (for the 2006 option grants, January 24, 2006). Equity awards may also be made to new executive officers upon hire or promotion, effective upon the first date of employment in the position. The compensation committee does not time equity grants to take advantage of information, either positive or negative, about the company which has not been publicly announced. The number of stock options awarded is typically based on the recommendations of independent consultants engaged by the compensation committee, and an NEO’s individual performance and results. Individual grant of stock option awards can either increase or decrease depending on a subjective assessment of each NEO’s performance over the last year, as well as expected contribution in future years.

2007 Performance Share Grants. On January 23, 2007, the compensation committee approved the 2007 Long-Term Incentive Plan. Under this plan, certain executive officers, including the NEOs, became eligible to earn performance shares in addition to receiving stock option awards. The initial grant of performance shares will be earned based upon annual earnings per share (“EPS”) goals over a three-year period beginning in 2007. A grantee may also earn, over the course of three years, a total number of shares ranging from 0% to 175% of the number of shares equal to his or her initial grant of performance shares, which range is based on the actual achievement of the predetermined EPS goals. Provided annual EPS goals are achieved, fifty percent of the initial grant of performance shares may be earned as of 2007, an additional thirty percent as of 2008, and the remaining twenty percent as of 2009, and will be vested in 2010, subject to the executive’s continued employment through the third anniversary of the grant date. The NEOs received the following initial grant of performance shares:

Named Executive Officer |  | EPS Performance Shares Granted in 2007
Patrick J. Sullivan |  | 30,000
Timothy M. Adams |  | 12,000
Daniel J. Levangie |  | 20,000
John P. McDonough |  | 10,000
A. Suzanne Meszner-Eltrich |  | 10,000

Guidelines for Stock Ownership—With the goal of encouraging long-term ownership of Cytyc common stock by executive management, the compensation committee adopted revised guidelines for target levels of stock ownership by executive officers in early 2007. The guidelines apply to vice presidents and above, and are in the process of implementation. To mitigate the need to place time restrictions on attaining the targets and avoid the need for executives to make significant out-of-pocket purchases or prematurely exercise options, executives are expected to retain a specified percent of the after-tax value of option exercises and vesting of restricted and performance shares until the stock ownership guideline is met.

The Company’s insider trading policy prohibits executives from engaging in certain transactions for the purpose of hedging the economic risk of his or her current or future ownership of shares.

Other Personal Benefits—The NEOs are eligible for the same health and welfare programs offered to exempt employees, including medical, dental and vision coverage, wellness programs, use of Cytyc’s employee assistance program, short and long-term disability, and paid time off in accordance with company policies. For programs to which employees contribute premiums, executives pay the same premiums as other exempt employees. In 2006, in addition to the benefits programs described above, which were available to all employees, Cytyc also provided to its executive officers and executives at the vice president level and above a financial services reimbursement plan, providing reimbursement for certain financial services not to exceed $3,000 per individual per calendar year, and an executive healthcare supplement program. Cytyc provided these additional benefits in order to maintain market competitiveness in its overall compensation and benefits packages. Effective January 1, 2007, Cytyc terminated the executive healthcare supplement program for its executive officers and increased the financial services reimbursement to $5,000 per individual. Effective January 1, 2008, Cytyc plans to terminate the executive healthcare supplement program for all executives at the vice president level and above who are not executive officers.

Post-Employment Compensation

Change of Control Agreements—Each of Cytyc’s executive officers, including NEOs, is party to a change of control severance agreement with the company. The compensation committee determined that such arrangements were appropriate based on their prevalence within the life science industry and the dynamic nature of mergers and acquisitions activity within this industry. Given the nature of the responsibilities of its executive officers, Cytyc believes they are likely to be involved in critical decisions relating to a potential change of control transaction and to be responsible for the successful implementation of such transactions, while being at risk of losing their job if a change of control transaction occurs. The change of control agreement is intended to provide sufficient protection for the executive officer to permit them to consider potential transactions that are in the best interest of Cytyc stockholders, without being unduly influenced by the effects of the transaction on their compensation. If an executive officer’s employment is terminated by him or her for good reason or by the company without cause following a change of control transaction, the executive officer will receive a lump sum payment equal to a specified number times the sum of salary and bonus (three times the sum of salary and bonus for Messrs. Sullivan and Levangie and 1.5 times for Messrs. Adams and McDonough and Ms. Meszner-Eltrich) if he or she is terminated within a certain period of the change of control transaction (two years for Messrs. Sullivan and Levangie and 18 months for Messrs. Adams and McDonough and Ms. Meszner-Eltrich). The change of control agreements are described in greater detail below under “Interests of Cytyc Executive Officers and Directors in the Merger.”

In addition, the stock options and performance shares held by the executive officers and executives at the vice president level and above provide for immediate acceleration of vesting upon a change of control transaction, without regard to continued employment.

Employee 401(k) Plan and Employee Stock Purchase Program —Cytyc maintains a retirement plan which is qualified for favorable tax treatment under the Internal Revenue Code—a defined contribution 401(k) plan.

B-55

##### Table of Contents

Cytyc also maintains an employee stock purchase program. These plans are generally available to all company employees. Each of the NEOs participates in the 401(k) plan, and Messrs. Adams and McDonough participate in the employee stock purchase plan.

Tax and Accounting Considerations—The compensation committee carefully considers the tax impact of Cytyc’s compensation programs on the company as well as on the NEOs. However, the compensation committee believes that decisions regarding executive compensation should be primarily based on whether they result in positive long-term value for Cytyc’s stockholders, customers, employees and other important stakeholders. The compensation committee considers the impact of Section 162(m) in structuring Cytyc’s executive compensation program. Section 162(m) limits Cytyc’s annual income tax deduction for compensation paid to each of Cytyc’s NEOs to $1 million to the extent the compensation does not meet the “qualified performance-based compensation” requirements of Section 162(m). To the extent reasonably possible in light of Cytyc’s compensation goals and objectives, the compensation paid to the NEOs has been structured so as to qualify as performance-based and to be deductible under Section 162(m). However, in light of the competitive nature of the market for executive talent, the compensation committee believes that it is more important to encourage the NEOs to remain focused on building stockholder value than to use a particular compensation practice or structure solely to ensure tax deductibility, and thus retains discretion to address tax deductibility of executive compensation as one key element of compensation decisions.

Patrick J. Sullivan and Daniel J. Levangie, employee directors of Cytyc, do not receive any compensation for services rendered as a director.

Cytyc’s non-employee directors are also eligible to participate in Cytyc’s 2004 Omnibus Stock Plan. Under the 2004 Omnibus Stock Plan, each non-employee director may be granted stock options and opportunities to make direct purchases of stock and other equity interests in Cytyc.

The Cytyc board of directors has currently approved an annual option grant to purchase up to 16,000 shares of common stock, which vests in one-twelfth increments on the first day of each calendar quarter for three years. Also, upon commencement of service as a director, each new non-employee director receives an option to purchase the same number of shares of common stock as the annual option grant in effect at that time. Each non-employee director is entitled, under Cytyc’s Amended and Restated Director Compensation Method Plan, to receive payment of the annual retainer fees for any calendar year either in cash or in shares of Cytyc common

stock. Each non-employee director is also entitled to receive an annual stock award of 1,000 shares of Cytyc common stock, which is earned monthly based on service. Lastly, each non-employee director is paid a cash fee for every meeting attended as set forth above. Each non-employee director may elect to defer for tax purposes the payment of the annual retainer, annual stock award and meeting attendance fees.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(1) Basis of Presentation

The accompanying condensed consolidated financial statements of Cytyc Corporation and subsidiaries (the “Company” or “Cytyc”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. These financial statements should be read in conjunction with the financial statements and notes included in Amendment No. 2 to the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2006.

The notes and accompanying condensed consolidated financial statements are unaudited. The information furnished reflects all adjustments, which, in the opinion of management, are necessary for a fair presentation of results for the interim periods. Such adjustments consisted only of normal recurring items. The interim periods are not necessarily indicative of the results expected for the full year or any future period.

The preparation of these condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates.

(2) Acquisition Activity

(a) Acquisition of Adeza Biomedical Corporation

On February 11, 2007, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Augusta Medical Corporation, a Delaware corporation and a newly-formed wholly-owned subsidiary of Cytyc (the “Purchaser”), and Adeza Biomedical Corporation, a Delaware corporation (“Adeza”). Pursuant to the Merger Agreement, the Purchaser commenced a cash tender offer to purchase all outstanding shares of Adeza’s common stock (the “Shares”) in exchange for $24.00 per share in cash (the “Offer Price”). On March 19, 2007, Purchaser acquired a majority of Adeza’s outstanding Shares through the tender offer. On April 2, 2007, pursuant to the terms of the Merger Agreement, Cytyc acquired Adeza through the merger (the “Merger”) of Purchaser with and into Adeza. The Merger was consummated without a meeting of the stockholders of Adeza in accordance with the Delaware General Corporation Law. In connection with the Merger, Adeza’s name was changed from “Adeza Biomedical Corporation” to “Cytyc Prenatal Products Corp.” As a result of the Merger, all remaining outstanding Shares were converted into the right to receive $24.00 per share in cash, without interest, other than Shares held by Cytyc or any of its subsidiaries or Shares held by Adeza stockholders that perfect their rights to appraisal in accordance with the Delaware General Corporation Law. The purchase price was paid out of the Company’s existing cash and the Company’s existing credit facility.

The aggregate purchase price for Adeza was $456.7 million, of which $451.7 million represented cash payable to Adeza shareholders and $5.0 million represented acquisition-related fees and expenses. As of March 31, 2007, Cytyc paid $365.0 million of the purchase price (net of $26.3 million of cash acquired) and have $65.4 million accrued related to the Adeza acquisition, most of which was paid during April 2007. The acquisition was accounted for as a purchase in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 141, Business Combinations, and accordingly, the results of operations of Adeza were included in the consolidated statement of loss from the date of acquisition of March 19, 2007. The purchase price was supported by estimates of future sales and earnings of Adeza, as well as the value of sales force and other projected synergies.

Purchase Price Allocation

The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of acquisition, for an aggregate purchase price of $456.7 million, including acquisition costs:

|  | Amount (in thousands) |
Cash and cash equivalents |  | $ | 26,346 |
Investment securities |  |  | 72,019 |
Other current assets |  |  | 10,865 |
Property and equipment |  |  | 431 |
Patents and developed technology |  |  | 142,800 |
Goodwill |  |  | 208,451 |
Other assets |  |  | 72 |
Current liabilities |  |  | (19,676 | )
Long-term liabilities |  |  | (1,251 | )
Net deferred tax liability |  |  | (26,881 | )
In-process research and development |  |  | 43,500 |
|  | $ | 456,676 |

As part of the purchase price allocation, all tangible and intangible assets and liabilities were identified and valued. Of the total purchase price, the Company allocated $61.9 million to acquired net tangible assets. The net deferred tax liability of $26.9 million is primarily comprised of $30.2 million of deferred tax assets relating to acquired net operating losses primarily related to net operating loss carry forwards and tax credits, offset by deferred tax liabilities of $57.1 million relating to patents and developed technology. The Company determined the fair value of Adeza’s tangible assets and liabilities based on a review of Adeza’s historical and then current financial statements and an understanding of the ongoing nature of the assets and liabilities.

The Company also allocated $142.8 million to the acquired patents and developed technology. The acquired patents expire at various dates through 2018. Based on the average life of the patent portfolio, the remaining economic life of the developed technology is expected to be approximately 12-15 years. The Company is amortizing the patents and developed technology over this period using the cash flow method, under which amortization is calculated and recognized based upon the Company’s estimated net cash flows over the life of the intangible asset, reflecting the pattern in which the economic benefits of the intangible asset are consumed in accordance with SFAS No. 142, Goodwill and Other Intangible Assets. The Company believes the patents provide sufficient coverage for differentiated products to sustain some competitive advantage in the marketplace over the average remaining life of the patents.

The Company also allocated $43.5 million of the purchase price to in-process research and development projects. This allocation represents the estimated fair value based on risk-adjusted cash flows related to the incomplete research and development activities. The incomplete research and development activities primarily were associated with Adeza’s development of Gestiva™, a therapeutic drug, which is currently pending final approval from the Food and Drug Administration (“FDA”), as well as an induction of labor diagnostic product.

The acquired in-process research and development was charged to expense as of the date of the acquisition and is included in the Company’s statement of loss for the three months ended March 31, 2007.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)—Continued

The Company valued the intangible assets acquired, including the portfolio of patents and technologies, and the in-process research and development projects, based on present value calculations of income using risk- adjusted cash flows for each product, an analysis of project accomplishments and remaining outstanding items, an assessment of overall contributions, as well as project risks. The value assigned to the in-process research and development projects was determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the net cash flows resulting from the projects, and discounting the net cash flows to their present value. The Company expects to continue its efforts on the in-process research and development projects through the end of 2008.

The projections used to value the acquired intangible assets and the in-process research and development projects were based on estimates of relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by the Company and its competitors, as well as estimates of cost of sales, operating expenses, and income taxes resulting from the acquired products and the in-process research and development projects. In addition, the projections reflect the Company’s expectation that improvements to the current products will continue to be made over the life cycle of the product lines. As a result, the completed technology that existed as of the acquisition date was assumed to represent a declining percentage of the products’ technological composition over time.

The rate utilized to discount the net cash flows to their present value was based on estimated weighted-average cost of capital calculations. A discount rate of 14% was used to value the acquired intangible assets and the in-process research and development projects. This discount rate was higher than the Company’s weighted-average cost of capital due to the earlier-stage life cycles of the acquired products, the inherent uncertainties surrounding the outcome of the projects and commercialization and development of the acquired intangible assets, the useful life of the acquired technology, the profitability levels of such technology, and the uncertainty of technological advances that were unknown at that time.

The allocation of the purchase price is substantially complete, with the remaining allocation to be completed primarily related to the resolution of tax matters.

Goodwill

The excess of the purchase price over the fair value of tangible and identifiable intangible net assets, as well as the in-process research and development projects, was allocated to goodwill, which is non-deductible for tax purposes and totaled $208.5 million. In accordance with SFAS No. 142, this goodwill will not be systematically amortized. Instead, the Company will perform an annual assessment for impairment by applying a fair-value-based test.

Pro Forma Results

Both periods include pro forma adjustments to reflect interest costs related to the borrowings on the line-of-credit facility (see Note 11). The pro forma results for the three months ended March 31, 2007 include $7.8 million of transaction fees and expenses incurred by Adeza prior to the acquisition related to the merger, but exclude $43.5 million of in-process research and development costs. The pro forma adjustments are based upon available information and certain assumptions that management believes are reasonable. The unaudited pro forma financial information is not intended to represent or be indicative of the consolidated results of operations or financial condition of the Company that would have been reported had the acquisition been completed as of the beginning of each period presented.

(b) Acquisition of Adiana Inc.

On March 16, 2007, the Company acquired Adiana, Inc. (“Adiana”), a privately-held company located in Redwood City, California. As a result of the acquisition of Adiana, all of its fully-diluted equity immediately prior to the acquisition was automatically converted into the right to receive an initial cash payment of $60 million, plus milestone payments. The milestone payments include (i) payment of up to $25 million tied to the timing of certain FDA milestone achievements of the Adiana permanent contraception product and (ii) potential contingent payments tied to future revenue performance milestones. The contingent payments are based on incremental sales growth of the Adiana permanent contraception product during the four-year period following FDA approval of this product and are subject to an aggregate cap of $130 million. No payments can be earned after December 31, 2012. According to the terms of the related merger agreement, total payments, including the initial cash payment, the potential FDA milestone payment and the four-year contingent payments, will not exceed $215 million.

The initial purchase price payment was paid out of the Company’s existing cash. Pursuant to the merger agreement, $3.0 million of the purchase price was placed in escrow to satisfy potential claims. The purchase price was supported by estimates of future sales and earnings of Adiana, as well as other projected synergies.

The aggregate purchase price for Adiana was $60.5 million, of which $59.4 million represented cash payable to Adiana shareholders and $1.1 million represented acquisition-related fees and expenses. As of March 31, 2007, the Company paid $58.1 million of the purchase price (net of $1.9 million of cash acquired) and have $0.5 million accrued related to the Adiana acquisition. The acquisition was accounted for as a purchase in accordance with SFAS No. 141, and accordingly, the results of operations of Adiana were included in the consolidated statement of loss from the date of acquisition.

Purchase Price Allocation

The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the date of acquisition for an aggregate purchase price of $60.5 million, including acquisition costs:

|  | Amount (in thousands) |
Cash and cash equivalents |  | $ | 1,931 |
Other current assets |  |  | 210 |
Property and equipment |  |  | 151 |
Other assets |  |  | 18 |
Net deferred tax asset |  |  | 19,973 |
Current liabilities |  |  | (4,412 | )
Long-term liabilities |  |  | (3,401 | )
In-process research and development |  |  | 46,000 |
|  | $ | 60,470 |

As part of the purchase price allocation, all tangible assets and liabilities were identified and valued. Of the total purchase price, the Company allocated $14.5 million to acquired net tangible assets. The net deferred tax asset of $20.0 million relates to acquired net operating losses and tax credits. The Company determined the fair value of Adiana’s tangible assets and liabilities based on a review of Adiana’s historical and then current financial statements and an understanding of the ongoing nature of the assets and liabilities.

The Company also allocated $46.0 million of the purchase price to an in-process research and development project. This allocation represents the estimated fair value based on risk-adjusted cash flows related to the incomplete research and development activities. The incomplete research and development activities are associated with the Adiana Complete Transcervical Sterilization System (“TCS”), a form of permanent female contraception intended as an alternative to tubal ligation, and primarily relate to activities to be performed in order to obtain FDA approval. The acquired in-process research and development was charged to expense as of the date of the acquisition and included in the Company’s statement of loss for the three months ended March 31, 2007.

The Company valued the in-process research and development project, based on present value calculations of income using risk-adjusted cash flows for, an analysis of project accomplishments and remaining outstanding items, an assessment of overall contributions, as well as project risks. The value assigned to the in-process research and development project was determined by estimating the costs to develop the acquired technology into a commercially viable product, estimating the net cash flows resulting from the project, and discounting the net cash flows to their present value. The Company expects to complete its efforts on the in-process research and development project in 2008.

The projections used to value the in-process research and development project were based on estimates of relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by the Company and its competitors, as well as estimates of cost of sales, operating expenses, and income taxes resulting from the in-process research and development project.

The rate utilized to discount the net cash flows to their present value was based on estimated weighted-average cost of capital calculations. A discount rate of 26% was used to value the in-process research and development project. The discount rate was higher than the Company’s weighted-average cost of capital due to the early-stage life cycle of the in-process research and development project, the inherent uncertainties

surrounding the commercialization and development of TCS, the useful life of the future product, the profitability levels of such technology, and the uncertainty of technological advances that were unknown at that time.

The excess of the fair value of tangible net assets over the purchase price of $3.2 million was allocated to expected contingent earn-out payments related to future milestones in accordance with SFAS No. 142 and recorded in long-term liabilities.

The initial allocation of the purchase price is substantially complete, with the remaining allocation to be completed primarily related to the resolution of tax matters.

The operating results of Adiana are not material to any periods presented and accordingly pro forma financial information is not presented.

(3) Amortization of Intangible Assets

Amortization expense related to identifiable intangible assets, which consists of the Company’s acquired patents and developed technology, was approximately $3.6 million and $2.4 million for the three months ended March 31, 2007 and 2006, respectively (see Note 10 for amortization expense by operating segment). Prior to 2007, the Company allocated amortization of all of its intangible assets to research and development within its condensed consolidated statements of income as the developed technology has benefited multiple line items (i.e., cost of sales and research and development) and any allocation that would have been made to cost of sales was not deemed to be material. During 2007, the Company acquired a significant amount of developed technology ($142.8 million) as part of its acquisition of Adeza and is including the amortization of such developed technology within cost of sales based upon its intended use. For the amortization of its other developed technology, beginning in 2007, the Company is allocating the majority to cost of sales based upon its determination that such developed technology is primarily being used to generate sales of its products. A portion of the amortization expense also will be allocated to research and development based upon the Company’s determination that such developed technology is primarily being utilized to support the Company’s research and development efforts (e.g., FirstCyte Breast Test).

Amortization expense related to identifiable intangible assets, which is an estimate for each future year and subject to change, is as follows:

|  | Amount
|  | (in thousands)
Remaining nine months ending December 31, 2007 |  | $ | 16,691
Year ending December 31, 2008 |  |  | 25,975

Year ending December 31, 2011 |  |  | 28,003
Thereafter |  |  | 192,338
Total |  | $ | 321,701

(4) Investment Securities

Investment securities at March 31, 2007 consist of commercial paper and municipal bonds as of and December 31, 2006 consist of only municipal bonds, all of which are classified as available-for-sale. The fair value of available-for-sale securities was determined based on quoted market prices at the reporting date for those securities. Available-for-sale securities are shown in the consolidated financial statements at fair market value with unrealized gains or losses recorded as a component of other comprehensive income.

(6) Net (Loss) Income Per Common Share

Basic net (loss) income per share is computed by dividing net (loss) income by the weighted average number of common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average number of common shares and potential common shares from outstanding stock options and convertible debt. As a result of the Company’s net loss during the three months ended March 31, 2007, all potential common shares from outstanding stock options and convertible debt, which totaled 10.3 million weighted average shares, were anti-dilutive and were excluded from the diluted net loss per share calculation. Potential common shares for outstanding stock options are calculated using the treasury stock method and represent incremental shares issuable upon exercise of the Company’s outstanding stock options. The treasury stock method is affected by the amount of stock-based compensation attributable to future services and therefore not yet recognized. The Company’s adoption of SFAS No. 123R, Share-Based Payment, on January 1, 2006, resulted in an increase in unrecognized stock-based compensation expense relating to unvested employee stock awards, which reduced the dilutive effect of assumed exercises of stock options for the three months ended March 31, 2006 by approximately two million shares. There was no such impact for the three months ended March 31, 2007, as the effect would have been anti-dilutive.

The following table provides a reconciliation of the net (loss) income and weighted average common shares used in calculating basic and diluted net (loss) income per share for the three months ended March 31, 2007 and 2006:

|  | Three Months Ended March 31,
|  | 2007 |  |  | 2006
|  | (in thousands, except per share data)
Numerator: |  |  |  |  |  |  |

Interest expense on convertible debt, net of tax |  |  | — |  |  |  | 1,138
Net (loss) income, as adjusted, for diluted earnings per share |  | $ | (51,209 | ) |  | $ | 30,502
Denominator: |  |  |  |  |  |  |
Basic weighted average common shares outstanding |  |  | 114,725 |  |  |  | 115,481
Dilutive effect of assumed exercise of stock options |  |  | — |  |  |  | 1,970
Dilutive effect of assumed conversion of convertible debt |  |  | — |  |  |  | 8,426
Weighted average common shares outstanding assuming dilution |  |  | 114,725 |  |  |  | 125,877
Basic net (loss) income per common share |  | $ | (0.45 | ) |  | $ | 0.25
Diluted net (loss) income per common and potential common share |  | $ | (0.45 | ) |  | $ | 0.24

For the three months ended March 31, 2007, diluted net loss per share excluded interest expense on convertible debt as well as the effect on weighted average diluted common shares outstanding of the assumed exercise of stock options and assumed conversion of convertible debt as such amounts would have been anti-dilutive. Diluted weighted average common shares outstanding for the three months ended March 31, 2006 excluded 50,875 potential common shares from stock options outstanding, because the exercise prices of such stock options were higher than the average closing price of the Company’s common stock as quoted on The NASDAQ Global Select Market during the period and, accordingly, their effect would be anti-dilutive.

(7) Stock-Based Compensation and Stock Incentive Plans

(a) Stock-Based Compensation

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123R, which requires all stock-based compensation to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The Company adopted SFAS No. 123R on January 1, 2006 using the modified prospective method and accordingly, prior period amounts have not been restated. In order to determine the fair value of stock options and employee stock purchase plan shares, the Company is using the Black-Scholes option pricing model and is applying the multiple-option valuation approach to the stock option valuation. The Company is recognizing stock-based compensation expense on a straight-line basis over the requisite service period of the awards for options granted following the adoption of SFAS No. 123R. For unvested stock options outstanding as of January 1, 2006, the Company will continue to recognize stock-based compensation expense using the accelerated amortization method prescribed in FASB Interpretation (“FIN”) No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans.

Estimates of the fair value of equity awards will be affected by the future market price of the Company’s common stock, as well as the actual results of certain assumptions used to value the equity awards. These

B-F-13

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)—Continued

assumptions include, but are not limited to, the related income tax impact, the expected volatility of the common stock, the number of stock options to be forfeited and exercised by employees, and the expected term of options granted.

As noted above, the fair value of stock options and employee stock purchase plan shares is determined by using the Black-Scholes option pricing model and applying the multiple-option valuation approach to the stock option valuation. The options have graded-vesting on an annual basis over an average vesting period of four years. In applying the multiple-option approach, each option “tranche” is separately valued based upon when the tranche vests. The Company estimates the expected option term by calculating the average period of time before the employees exercise their options and adds this to the vesting period of each tranche. Historically, this period of time has averaged one year from the date the options vest. The expected term of employee stock purchase plan shares is the average of the remaining purchase periods under each offering period. For equity awards granted prior to the adoption of SFAS No. 123R, the volatility of the common stock was estimated using historical volatility. For equity awards granted since January 1, 2006, the volatility of the common stock is estimated using a combination of historical and implied volatility, as discussed in Staff Accounting Bulletin (“SAB”) No. 107, Considering the interaction between SFAS No. 123R and Certain Securities and Exchange Commission Rules and Regulations. By using this combination, the Company is taking into consideration the historical realized volatility, as well as factoring in estimates of future volatility that the Company believes will differ from historical volatility as a result of the Company’s product diversification over the last two years, the market performance of the common stock, the volume of activity of the underlying shares, the availability of actively traded common stock options, and overall market conditions.

The risk-free interest rate used in the Black-Scholes option pricing model is determined by looking at historical U.S. Treasury zero-coupon bond issues with remaining terms equal to the expected terms of the equity awards. In addition, an expected dividend yield of zero is used in the option valuation model, because the Company does not expect to pay any cash dividends in the foreseeable future. Lastly, in accordance with SFAS No. 123R, the Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. In order to determine an estimated pre-vesting option forfeiture rate, the Company used historical forfeiture data. This estimated forfeiture rate has been applied to all unvested options outstanding as of January 1, 2006 and to all options granted since January 1, 2006. Therefore, stock-based compensation expense is recorded only for those options that are expected to vest.

In February 2007, the Company issued 160,700 performance-based stock units (“performance shares”) that vest over a three-year period based upon specific future performance milestones. A grantee may also earn, over the course of three years, a total number of shares ranging from 0% to 175% of the number of shares equal to his or her initial grant of performance shares, which range is based on the actual achievement of the performance milestones. The market price of the Company’s common stock on date of grant was $30.44. Each period the Company will assess its estimate of the probability that such performance milestones will be met and, if necessary, will adjust the related stock-based compensation expense. The Company is recording stock-based compensation expense for these equity awards over the three-year vesting period assuming all future performance milestones will be met.

The underlying assumptions used in the Black-Scholes model were as follows for options granted during the three months ended March 31, 2007 and 2006:

Prior to January 1, 2006, the Company accounted for stock options using the intrinsic value method, pursuant to the provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees. Under this method, stock-based compensation expense was measured as the difference between the option’s exercise price and the market price of the Company’s common stock on the date of grant.

Expected volatility |  | 28 | % |  | 32 | %

As of March 31, 2007, total unrecognized stock-based compensation expense relating to unvested employee stock awards, adjusted for estimated forfeitures, was $34.6 million. This amount is expected to be recognized over a weighted-average period of 2.6 years. If actual forfeitures differ from current estimates, total unrecognized stock-based compensation expense will be adjusted for future changes in estimated forfeitures.

(b) Employee and Director Incentive Plans

The Cytyc Corporation 2004 Omnibus Stock Plan (the “2004 Omnibus Plan”), which is the Company’s primary plan for grants of equity, provides for the issuance of up to 12,250,000 shares of the Company’s common stock, no more than 8,200,000 of which shares may be issued as awards other than stock options or stock appreciation rights. The 2004 Omnibus Plan provides for grants of various incentives, including stock options and other stock-based awards. At March 31, 2007, 3,974,527 shares were available for future grant under the 2004 Omnibus Plan.

The following table summarizes options outstanding, by stock plan, as of March 31, 2007:

(10) Segment Information

SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, requires certain financial and supplementary information to be disclosed for each reportable operating segment of an enterprise, as defined. During the third quarter of 2006, the Company established the domestic diagnostic products and domestic surgical products divisions, each managed by a divisional president. Effective for the first quarter of 2007, as a result of the oversight of each segment by a divisional president, including review and ownership of discrete financial information, operating expenses are captured in the segment to which they relate, except for certain corporate expenses that benefit multiple operating segments and stock-based compensation expense (such expenses are included in “Corporate” below). Segment figures for 2006 have been restated to reflect the changes described above.

Financial information for the three segments is included below for all periods presented and each segment is described as follows:

Domestic Diagnostic Products—This segment develops and markets the ThinPrep® System in the United States primarily for use in diagnostic cytology testing applications focused on women’s health. The ThinPrep System is widely used for cervical cancer screening. The ThinPrep System consists of any one or more of the following: the ThinPrep 2000 Processor, ThinPrep 3000 Processor, ThinPrep Imaging System, and related reagents, filters, and other supplies, such as the ThinPrep Pap Test and the Company’s proprietary ThinPrep PreservCyt Solution. As a result of the Company’s acquisition of Adeza on March 19, 2007, this segment also develops and markets FullTerm™, The Fetal Fibronectin Test, which offers clinical and cost benefits for the assessment of the risk of pre-term birth.

SFAS No. 131 also requires that certain enterprise-wide disclosures be made related to products and services, geographic areas and significant customers. During the three months ended March 31, 2007 and 2006, the Company derived its sales from the following geographies (as a percentage of net sales):

|  | Three Months Ended March 31, |
|  | 2007 |  |  | 2006 |
United States |  | 88 | % |  | 89 | %
International |  | 12 | % |  | 11 | %

During the three months ended March 31, 2007 and the three months ended March 31, 2006, no customer represented 10% or more of consolidated net sales.

(11) Long-Term Debt, Contractual Obligations, Commitments and Contingencies

Long-Term Debt and Contractual Obligations:

Credit Agreement—On June 30, 2006, the Company entered into a five-year Credit Agreement (the “Credit Agreement”) with a syndicate of lenders. The Credit Agreement provided for a $150 million senior unsecured revolving credit facility. On October 6, 2006, the Company and its related lenders amended the Credit Agreement in order to, among other items, increase the committed amount of the revolving credit facility to $345 million and to include one additional lender into the syndicate of lenders. The Company may request an increase in available borrowings under the Credit Agreement by an additional amount of up to $155 million (for a maximum amount of $500 million) upon satisfaction of certain conditions. These increased borrowings may be provided either by one or more existing lenders upon the Company obtaining the agreement of such lender(s) to increase commitments or by new lenders being added to the credit facility. The loan proceeds are available to be used by the Company and its subsidiaries to finance working capital needs and for general corporate purposes, including certain permitted business acquisitions. On May 14, 2007, the Company and its related lenders amended the Credit Agreement in order to: (1) extend to July 31, 2007 the delivery deadline for both the audited financial statements for the fiscal year ended December 31, 2006 and the unaudited financial statements for the fiscal quarter ended March 31, 2007 and (2) amend the negative covenant concerning Indebtedness (as such term is defined in the Credit Agreement) to increase the maximum size of the receivables financing facility permitted thereunder from $50 million to $100 million.

Amounts under the Credit Agreement may be borrowed, repaid and re-borrowed by the Company from time to time until the maturity of the Credit Agreement on June 30, 2011. Voluntary prepayments and commitment reductions requested by the Company under the Credit Agreement are permitted at any time without penalty (other than customary breakage costs relating to the prepayment of any drawn loans) upon proper notice and subject to a minimum dollar requirement. Borrowings under the Credit Agreement bear interest at a floating rate, which will be, at the Company’s option, either LIBOR plus an applicable margin (which is subject to adjustment based on financial ratios), or a base rate.

The Credit Agreement requires the Company to comply with maximum leverage and minimum fixed charge coverage ratios. The Credit Agreement contains affirmative and negative covenants, including limitations on additional debt, liens, certain investments, and acquisitions outside of the healthcare business. The Credit Agreement also includes events of default customary for facilities of this type. Upon the occurrence of an event of default, all outstanding loans may be accelerated and/or the lenders’ commitments terminated.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)—Continued

As of March 31, 2007, the Company had $200.5 million outstanding under this Credit Agreement at an interest rate of 5.32% (LIBOR) plus a margin of 0.475% providing a total interest rate of 5.795%.

Convertible Notes—On March 22, 2004, the Company completed the sale (the “Offering”) of $250 million aggregate principal amount of its 2.25% convertible notes due 2024. The convertible notes were sold to qualified institutional buyers pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended. The notes bear interest at a rate of 2.25% per year on the principal amount, payable semi-annually in arrears in cash on March 15 and September 15 of each year, beginning September 15, 2004. The holders of the notes may convert the notes into shares of the Company’s common stock at a conversion price of $29.67 per share, subject to adjustment, prior to the close of business on March 15, 2024, subject to prior redemption or repurchase of the notes, under any of the following circumstances: (1) during any calendar quarter commencing after June 30, 2004 if the closing sale price of the Company’s common stock exceeds 120% of the conversion price for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter (if the specified threshold is met, the notes will thereafter be convertible at any time at the option of the holder prior to the close of business on March 15, 2024); (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each day of such period was less than 98% of the product of the closing sale price of the Company’s common stock and the number of shares issuable upon conversion of $1,000 principal amount of the notes; (3) if the notes have been called for redemption; or (4) upon the occurrence of specified corporate events.

Holders may require the Company to repurchase the notes on March 15 of 2009, 2014 and 2019 at a repurchase price equal to 100% of their principal amount, plus accrued and unpaid interest, including contingent interest and liquidated damages, if any, to, but excluding, the repurchase date. The Company may redeem any of the notes beginning March 20, 2009, by giving holders at least 30 days’ notice.

Commitments:

Earn-out Payments—Part of the purchase price for Adiana includes contingent earn-out payments tied to future performance milestones (see Note 2(b)).

Lease Commitments:

On April 23, 2007, the Company signed a non-cancelable lease agreement for a building with approximately 164,354 square feet. This facility is located in Alajuela, Costa Rica, and will be used as an additional manufacturing facility and office building. The term of the lease is for a period of approximately ten years commencing on or around February 2008. The term of the lease may be extended for two consecutive five-year terms.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)—Continued

As part of Cytyc’s acquisitions of Adeza and Adiana during the first quarter of 2007, Cytyc assumed non-cancelable leases for buildings located in California which have cash payments over the next two years totaling $0.3 million per year.

Finance Lease Obligation—On July 11, 2006, the Company signed a non-cancelable lease agreement for a building with approximately 146,000 square feet located in Marlborough, Massachusetts, to be principally used as an additional manufacturing facility. In 2011, the Company will have an option to lease an additional 30,000 square feet. As part of the lease agreement, the lessor agreed to allow the Company to make significant renovations to the facility to prepare the facility for the Company’s manufacturing needs. The Company is responsible for a significant amount of the construction costs and therefore was deemed under Generally Accepted Accounting Principles to be the owner of the building during the construction period, in accordance with Emerging Issues Task Force (“EITF”) No. 97-10, The Effect of Lessee Involvement in Asset Construction. During the year ended December 31, 2006, the Company recorded the fair market value of the facility of $13.2 million within property and equipment on its consolidated balance sheet, with an offsetting increase to current and non-current liabilities. The Company plans to begin occupying the facility during the second quarter of 2007. The term of the lease is for a period of approximately 12 years commencing on November 14, 2006.

Future minimum lease payments, including principal and interest, under this lease are as follows:

|  | Amount
|  | (in thousands)
Remaining nine months ending December 31, 2007 |  | $ | 556
Year ending December 31, 2008 |  |  | 924

Total minimum payments |  |  | 12,296

Total |  | $ | 6,523

Restructuring—During the fourth quarter of 2006, Company management approved a restructuring plan designed to reduce future operating expenses, by consolidating its Mountain View, California operations into its existing operations in Costa Rica and Massachusetts. In connection with this plan, the Company incurred $2.9 million of restructuring costs during the fourth quarter of 2006 related to severance expenses and accrued $0.3 million related to retention costs. The Company expects to incur and pay additional restructuring costs in 2007 of approximately $5 million to $6 million, primarily resulting from retention costs and incremental depreciation of leasehold improvements.

CYTYC CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)—Continued

During the three months ended March 31, 2007, Cytyc recognized restructuring expense of $1.2 million primarily related to retention costs for employees which are recognized in the Company’s statement of (loss) income on a straight-line basis over the employment period. During the first quarter of 2007, the Company made payments for severance and retention in the amount of $0.2 million and $0.4 million, respectively.

Contingencies—On June 16, 2003, Cytyc filed a suit for Declaratory Judgment in United States District Court for the District of Massachusetts asking the court to determine and declare that certain of TriPath Imaging, Inc.’s (“TriPath”) patents are invalid and not infringed by the Company’s ThinPrep Imaging System. On June 17, 2003, TriPath announced that it had filed a lawsuit against the Company in the United States District Court for the Middle District of North Carolina alleging patent infringement, false advertising, defamation, intentional interference, unfair competition, and unfair and deceptive trade practices. The non-patent claims have been dismissed and the patent cases have since been consolidated into a single action. A hearing occurred on August 2, 2006 in the United States District Court for the District of Massachusetts to hear oral arguments on summary judgment motions. The Court has scheduled a trial start date of October 29, 2007. The Company continues to believe that the claims against it are without merit and intends to vigorously defend this suit. Given the current status of the litigation, the Company is unable to reasonably estimate the ultimate outcome of this case.

The Company is also involved in ordinary, routine litigation incidental to its business. Although the outcomes of these other lawsuits and claims are uncertain, management does not believe that, individually or in the aggregate, these other lawsuits and claims will have a material adverse effect on the Company’s business, financial condition, results of operations or liquidity.

(12) Income Taxes

The Company’s effective tax rate for the three months ended March 31, 2007 was 60.0% as compared to 36.5% for the three months ended March 31, 2006. Exclusive of the effects of the non-deductible in-process research and development charges incurred in connection with Cytyc’s acquisitions of Adeza and Adiana in March 2007 the Company’s effective tax rate would have been 33.4% including the recognition of a tax benefit related to an examination closed during the period.

On January 1, 2007, the Company adopted FIN No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109, which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN No. 48 prescribes a recognition threshold and measurement criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN No. 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition and defines the criteria that must be met for the benefits of a tax position to be recognized. As a result of its adoption of FIN No. 48, the Company has recorded the cumulative effect of the change in accounting principle of $0.5 million as a decrease to opening retained earnings.

The Company had gross unrecognized tax benefits of approximately $12.8 million as of January 1, 2007. Of this amount, $6.8 million (net of federal benefit on state issues) represents the amount of unrecognized tax benefits as of January 1, 2007 that, if recognized, would result in a reduction of the Company’s effective tax rate. At March 31, 2007, the Company had $11.3 million of unrecognized tax benefits $5.3 million of which, if recognized, would result in the reduction of the Company’s effective tax rate. The decrease during the three month period ended March 31, 2007 in unrecognized tax benefits is primarily the result of the recognition of approximately $1.6 million of tax benefits related to an examination that closed during the period.

Consistent with its historical financial reporting, the Company has elected to classify interest expense related to income tax liabilities, when applicable, as part of income tax expense in its consolidated statement of (loss) income. As of January 1, 2007, accrued interest was approximately $0.9 million, net of federal benefit. As of January 1, 2007, no penalties have been accrued.

The Company and its subsidiaries are subject to United Sates federal income tax, as well as income tax of multiple state income and foreign jurisdictions. The last years examined by the Internal Revenue Service and the Massachusetts Department of Revenue were 2004 and 2003, respectively, and all years up through and including those years are closed by examination.

(13) | Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. Among other requirements, SFAS No. 157 defines fair value and establishes a framework for measuring fair value and also expands disclosure requirements regarding fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those years. Cytyc is evaluating the impact of adopting SFAS No. 157 on its financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115, which permits entities to measure various financial instruments and certain other items at fair value at specified election dates. The election must be made at initial recognition of the financial instrument, and any unrealized gains or losses must be reported at each reporting date. SFAS No. 159 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Company is currently evaluating the potential impact that adopting SFAS No. 159 will have on its consolidated financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

ON THE CONSOLIDATED FINANCIAL STATEMENTS

To the Board of Directors and Stockholders of

Cytyc Corporation

Marlborough, Massachusetts

We have audited the accompanying consolidated balance sheets of Cytyc Corporation and subsidiaries (the “Company”) as of December 31, 2006 and 2005, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2006. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2006 and 2005, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 15 to the consolidated financial statements, the accompanying consolidated financial statements as of December 31, 2006 and 2005 and for each of the three years in the period ended December 31, 2006 have been restated.

As discussed in Note 9 to the consolidated financial statements, the Company changed its method of accounting for stock-based compensation on January 1, 2006, as required by Statement of Financial Accounting Standards No. 123R, Share-Based Payment.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006 (as revised), based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 1, 2007 (May 18, 2007 as to the effect of the material weakness described in Management’s Report on Internal Control over Financial Reporting (As Revised)) included in the Company’s Annual Report on Form 10-K/A (Amendment No. 2) expressed an unqualified opinion on management’s assessment of the effectiveness of the Company’s internal control over financial reporting and an adverse opinion on the effectiveness of the Company’s internal control over financial reporting.

(1) The Company

Cytyc Corporation and subsidiaries (“Cytyc” or the “Company”) is a diversified diagnostic and medical device company that designs, develops, manufactures, and markets innovative and clinically effective diagnostic and surgical products. Cytyc products cover a range of cancer and women’s health applications, including cervical cancer screening, treatment of excessive menstrual bleeding, radiation treatment of early-stage breast cancer, and radiation treatment of patients with malignant brain tumors. The Company’s goal is to become the market leader in providing innovative technologies that enable physicians and laboratories to improve patients’ lives throughout the world.

Cytyc has three reportable segments: domestic diagnostic products, domestic surgical products, and international. Cytyc’s product lines primarily include: the ThinPrep® System, the NovaSure® System, the MammoSite® Radiation Therapy System and the GliaSite® Radiation Therapy System.

The ThinPrep System is an automated system for the preparation and screening of cervical specimens and non-gynecological samples on microscope slides. The ThinPrep System consists of any one or more of the following: the ThinPrep 2000 Processor, ThinPrep 3000 Processor, ThinPrep Imaging System, and related reagents, filters, and other supplies, such as the ThinPrep Pap Test and the Company’s proprietary ThinPrep PreservCyt® Solution.

The NovaSure System is an innovative endometrial ablation device to treat menorrhagia, or excessive menstrual bleeding. The NovaSure System primarily consists of a disposable, hand-held, single-use device and a controller that delivers radio frequency, or RF, energy to the endometrial wall of the uterus to ablate the endometrium. The NovaSure RF Controller generates and delivers the radiofrequency energy, monitors several critical treatment and safety parameters, and automatically controls other aspects of the procedure.

The MammoSite Radiation Therapy System is a single-use device for the treatment of early-stage breast cancer, which incorporates a patented balloon catheter that positions a therapeutic radiation source directly into the resection cavity created after removal of a tumor from the breast. The MammoSite System delivers optimally dosed radiation to the tissue that is at the highest risk for cancer recurrence while minimizing radiation exposure.

The GliaSite System is used for the treatment of malignant brain tumors and works in the same manner and utilizes similar technology as the MammoSite System, using Iotrex, a proprietary, liquid radiation source for which Cytyc has an exclusive license. The GliaSite System provides a full course of post-surgical radiation therapy that can be delivered even after a full course of external beam radiation therapy has been given to a patient.

As described in Note 9, on January 1, 2006, the Company changed its method of accounting for stock-based compensation, as required by Statement of Financial Accounting Standards (“SFAS”) No. 123R, Share-Based Payment.

(2) Summary of Significant Accounting Policies

The accompanying consolidated financial statements reflect the application of certain significant accounting policies, as discussed below and elsewhere in the notes to the consolidated financial statements. The preparation of these consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

December 31, 2006

(a) Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. All intercompany transactions and balances have been eliminated in consolidation.

(b) Foreign Currency Translation

The accounts of the Company’s foreign subsidiaries are translated in accordance with SFAS No. 52, Foreign Currency Translation. The Company has determined that the functional currency of its subsidiaries should be their local currencies, with the exception of its subsidiary in Costa Rica, whose functional currency is the US dollar. For all except the Costa Rica subsidiary, assets and liabilities of the foreign subsidiaries are translated at the rates of exchange in effect at year-end. Revenues and expenses are translated using exchange rates in effect during the year. As a result, gains and losses from foreign currency translation are included in accumulated other comprehensive income within stockholders’ equity in the accompanying consolidated balance sheets. Foreign currency transaction gains or losses are recorded immediately to income. During the fourth quarter of 2006, the Company recorded a realized foreign currency gain of $1.9 million on the sale of its Vision Systems Limited shares (see Note 4(d)). The Company had total realized and unrealized net foreign currency transaction gains (losses) of $2.5 million, $(1.5) million and $0.1 million in 2006, 2005 and 2004, respectively.

(c) Financial Instruments

The estimated fair market values of the Company’s financial instruments, which include marketable securities, accounts receivable and accounts payable, approximate their carrying values due to the short-term nature of these instruments. Financial instruments that potentially subject the Company to concentrations of credit risk are principally cash, cash equivalents, investment securities and accounts receivable. Investments are placed in highly-rated financial institutions. Concentration of credit risk with respect to accounts receivable is limited to certain customers to whom the Company makes substantial sales. To reduce risk, the Company routinely assesses the financial strength of its customers and, as a consequence, believes that its accounts receivable credit risk exposure is limited. No customer represented more than 10% of the accounts receivable balance as of December 31, 2006 and 2005. The fair market value of the Company’s long-term debt, which consists of its $250 million Convertible Notes, is approximately $272 million based on quoted market prices as of December 31, 2006.

(d) Cash and Cash Equivalents

Cash equivalents consist of municipal bonds with maturities, at date of purchase, of three months or less.

(e) Investment Securities

The Company follows the provisions of SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. Investment securities are classified as available-for-sale and recorded at fair market value with the unrealized gains and losses reported as a component of accumulated other comprehensive income in stockholders’ equity (see Note 2(s)). The Company would have the ability and intent to hold securities should fair value be less than cost. At December 31, 2006 investment securities consist of municipal bonds. At December 31, 2005, investment securities consisted of municipal bonds, as well as auction rate securities (“ARS”) totaling $65.1 million. Although the ARS generally have original maturities in excess of one year from date of purchase, the underlying interest rates on these securities typically reset within one month. Therefore,

B-F-31

##### Table of Contents

CYTYC CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

December 31, 2006

these ARS are priced and subsequently traded as investment securities because of remarketing and the interest rate reset feature.

At December 31, 2006 and 2005, the cost basis, aggregate fair value, gross unrealized holding gains and losses and average months to maturity, by major security type, are as follows:

|  | Amortized Cost |  | Gross Unrealized Holding Gains |  | Gross Unrealized Holding Losses |  |  | Fair Value
|  | (in thousands)
December 31, 2006 |  |  |  |  |  |  |  |  |  |  |  |  |
Municipal Bonds (average maturity of 0.7 months) |  | $ | 157,030 |  | $ | — |  | $ | — |  |  | $ | 157,030
December 31, 2005 |  |  |  |  |  |  |  |  |  |  |  |  |
Municipal Bonds (average maturity of 5.2 months) |  | $ | 32,152 |  | $ | — |  | $ | (76 | ) |  | $ | 32,076
Auction Rate Securities (average interest rate reset of 0.6 months) |  |  | 65,075 |  |  | — |  |  | — |  |  |  | 65,075
|  | $ | 97,227 |  | $ | — |  | $ | (76 | ) |  | $ | 97,151

(f) Allowance for Doubtful Accounts

The Company maintains reserves for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. These reserves are determined based upon historical experience and any specific customer collection issues that have been identified. Historically, the Company has not experienced significant credit losses related to an individual customer or groups of customers in any particular industry or geographic area.

(g) Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market and consist of materials, labor and manufacturing overhead.

(h) Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation and amortization. Expenditures for repairs and maintenance are charged to expense when incurred and additions or improvements are capitalized. The Company provides for depreciation and amortization by charges to operations, on a straight-line basis, in amounts estimated to allocate the cost of the assets over their estimated useful lives as follows:

Asset Classification |  | Estimated Useful Life
Equipment |  | 3-7 Years
Equipment under customer usage agreements |  | 3-8 Years
Computer equipment and software |  | 3-5 Years
Furniture and fixtures |  | 3-10 Years
Building |  | 40 Years
Leasehold improvements |  | Lesser of life or lease term

December 31, 2006

Leases—The Company evaluates and classifies its leases as operating or capital for financial reporting purposes. Minimum base rent for the Company’s operating leases, which generally have escalating rentals over the term of the lease, is recorded on a straight-line basis over the initial lease term and those renewal periods, if any, that have been exercised. All but one of the Company’s leases are classified as operating leases.

During 2006, the Company disbursed cash for property and equipment to build out and equip one of its leased facilities and pursuant to the provisions of Emerging Issues Task Force (“EITF”) 97-10, The Effect of Lessee Involvement in Asset Construction, the Company is deemed to be the owner of the facility during the construction period. As such, this lease is not classified as an operating lease and the Company recorded the fair market value of the facility within property and equipment on its consolidated balance sheet, with an offsetting increase to accrued expenses and other non-current liabilities. At the completion of the construction period, the Company will review the lease for potential sale-leaseback treatment.

(i) Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized but, instead, are measured for impairment at least annually, or whenever events indicate that there may be an impairment. Other identifiable intangible assets are amortized over their estimated useful lives and reviewed for impairment if circumstances warrant.

The Company has selected July in which to perform its annual evaluation of goodwill for impairment. As of July 31, 2006 and 2005, it was determined that the carrying amount of goodwill did not exceed its fair value and, accordingly, no impairment loss existed. There were no indicators of impairment subsequent to this annual review that require further assessment. Other intangible assets, such as acquired patents and developed technology, are being amortized over their estimated useful lives, which range from 3 years to 25 years. Impairment of these other intangible assets is determined as described in Note 2(k).

The intangible assets the Company acquired as part of its acquisitions, which primarily include patents and developed technology, are being amortized using the cash flow method over 15 years. Under the cash flow method, amortization is calculated and recognized based upon the Company’s estimated net cash flows over the life of the intangible asset, reflecting the pattern in which the economic benefits of the intangible asset are consumed in accordance with SFAS No. 142, Goodwill and Other Intangible Assets. The Company believes the patents provide sufficient coverage for differentiated products to sustain some competitive advantage in the marketplace over the average remaining life of the patents.

Amortization expense related to the identifiable intangible assets, which consists of the Company’s acquired patents and developed technology, was $10.9 million, $6.8 million and $3.1 million for 2006, 2005 and 2004, respectively (see Note 2(t) for amortization expense by operating segment). Amortization expense related to identifiable intangible assets, which is an estimate for each future year and subject to change, is as follows:

|  | Amount
|  | (in thousands)
2007 |  | $ | 14,602
2008 |  |  | 17,414
2009 |  |  | 19,695
2010 |  |  | 19,282
2011 |  |  | 18,005
Thereafter |  |  | 93,479
Total |  | $ | 182,477

(j) Other Assets

Other assets consist primarily of unamortized deferred financing costs of $4.6 million and $5.2 million as of December 31, 2006 and 2005, respectively, and private equity investments of $3.5 million and $1.2 million as of December 31, 2006 and 2005, respectively. The unamortized deferred financing costs related to the Company’s $250 million convertible notes are being amortized over the life of the expected five-year repayment period and the deferred financing costs related to the Company’s line of credit facility, entered into on June 30, 2006 and amended on October 6, 2006, are being amortized over the five-year life of the line of credit agreement (see Note 7).

During 2005, the Company entered into a $5.0 million private equity investment commitment with a limited liability partnership, which may be paid over the succeeding three years. As of December 31, 2006, approximately $1.6 million of this investment has been paid. The Company is accounting for this investment under the cost method, since it does not have the ability to exercise significant influence and, as of December 31, 2006 and 2005, holds less than three percent of the partnership’s voting stock, among other factors. In addition, in March 2006, the Company entered into a $1.9 million private equity investment agreement with a corporation, in which the Company received shares of preferred stock in exchange for granting a non-exclusive license to certain of the Company’s patents. The Company is accounting for this investment under the cost method, since it does not have the ability to exercise significant influence and, as of December 31, 2006, holds less than 20 percent of the corporation’s voting stock, among other factors. The Company’s determination of whether it has significant influence over an investment requires judgment. If at any time the private equity investment in the limited liability partnership exceeds three percent of the partnership’s voting stock, the private equity investment entered into in March 2006 exceeds 20 percent of the corporation’s voting stock, or the Company determines that it has the ability to exercise significant influence over either entity, among other factors, the Company will begin to account for the related investment under the equity method. In addition, the Company regularly reviews these investments for impairment indicators. To date, no impairment indicators have been identified relating to these investments.

(k) Long-lived Assets

The Company accounts for impairments of long-lived assets subject to amortization using SFAS No. 144, Accounting for Impairment or Disposal of Long-Lived Assets. SFAS No. 144 requires that companies (1) recognize an impairment loss only if the carrying amount of a long-lived asset is not recoverable based on its undiscounted future cash flows and (2) subsequently measure an impairment loss as the difference between the carrying amount and fair value of the asset.

(l) Product Warranty Obligations

The Company records a liability for product warranty obligations at the time of sale based upon historical warranty experience. The term of the warranty is generally twelve months. The Company also records an additional liability for specific warranty matters when they become known and are reasonably estimable. Product warranty obligations are included in accrued expenses.

(m) Restructuring

Restructuring is recognized and measured in accordance with the provisions of SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. Under SFAS No. 146, restructuring charges include, but are not limited to, severance and related costs and contract termination costs, as well as costs associated with the exit from leased facilities (see Note 11).

(n) Revenue Recognition

The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the sales price is fixed or determinable, and collectibility of the resulting receivable is reasonably assured. Revenue for contracts which contain multiple deliverables is allocated among the separate units based upon their relative fair values. The Company generally recognizes revenue on product sales upon shipment or upon delivery, depending on the shipping terms of the transaction and when delivery is deemed to have occurred. Provisions for estimated discounts and rebates are recorded as a reduction of net sales in the same period revenue is recognized. For equipment sales where the Company is obligated to perform installation or training that is deemed critical to the equipment’s functionality, revenue is deferred until after installation or training has occurred.

The Company also sells disposable supplies under customer usage agreements. Under customer usage agreements, the Company installs its equipment (for example, a ThinPrep Processor or a ThinPrep Imaging System) at customer sites and customers commit to purchasing minimum quantities of disposable supplies at a stated price (generally including a usage fee for the equipment) over a defined contract term, which is typically between three and five years. Revenue is recognized over the term of the customer usage agreement as disposable supplies are delivered. Accordingly, no revenue is recognized upon delivery of the equipment.

Revenues from sales of service contracts are deferred and recognized ratably over the service period. The Company also rents its equipment to customers. Revenues from rental agreements are recorded over the terms of the rental agreements.

Freight revenue billed to customers is included in net sales and expenses incurred for shipping products to customers are included in cost of sales.

(o) Research and Development Costs

Research and development costs are charged to operations as incurred.

(p) Income Taxes

The Company records deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement and tax basis of assets and liabilities, as measured by enacted tax rates anticipated to be in effect in the periods when these differences are expected to reverse. A valuation allowance is provided to the extent realization of tax assets is not considered likely.

(q) Net Income Per Common Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share is computed by dividing net income by the weighted average number of common shares and potential common shares from outstanding stock options and convertible debt. Potential common shares for outstanding stock options are calculated using the treasury stock method and represent incremental shares issuable upon exercise of the Company’s outstanding stock options. The treasury stock method is affected by the amount of stock-based compensation attributable to future services and therefore not yet recognized. The Company’s adoption of SFAS No. 123R on January 1, 2006 resulted in an increase in unrecognized stock-based compensation expense relating to unvested employee stock awards, which reduced the dilutive effect of assumed exercises of stock options for the year ended December 31, 2006 by 1,690,635 shares.

Diluted net income per common and potential common share |  | $ | 1.16 |  | $ | 0.94 |  | $ | 0.63

Diluted weighted average common shares outstanding exclude 3,921,706, 2,595,931 and 4,219,596 potential common shares from stock options outstanding for the years ended December 31, 2006, 2005 and 2004, respectively, because the exercise prices of such stock options were higher than the average closing price of the Company’s common stock as quoted on The NASDAQ National Market during the periods mentioned and, accordingly, their effect would be anti-dilutive.

(r) Stock-Based Compensation

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123R, which requires all stock-based compensation to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The Company adopted SFAS No. 123R on January 1, 2006 using the modified prospective method and accordingly, prior period amounts have not been restated. In order to determine the fair value of stock options and employee stock purchase plan shares, the Company is using the Black-Scholes option pricing model and is applying the multiple-option valuation approach to the stock option valuation. The Company is recognizing stock-based compensation expense on a straight-line basis over the requisite service period of the awards for options granted following the adoption of SFAS No. 123R. For unvested stock options outstanding as of January 1, 2006, the Company will continue to recognize stock-based compensation expense using the accelerated amortization method prescribed in FASB Interpretation (“FIN”) No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans. Prior to January 1, 2006, the Company accounted for stock options using the intrinsic value method, pursuant to the provisions of Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees. Under this method, stock-based compensation expense was measured as the difference between the option’s exercise price and the market price of the Company’s common stock on the date of grant.

(s) Comprehensive Income

SFAS No. 130, Reporting Comprehensive Income, establishes standards for the reporting and display of comprehensive income and its components in the consolidated financial statements. Comprehensive income is the total of net income and all other non-owner changes in equity including such items as unrealized holding gains (losses) on securities classified as available-for-sale and foreign currency translation adjustments, reflected net of tax. The Company has chosen to disclose comprehensive income in the accompanying consolidated statements of stockholders’ equity.

The components of accumulated other comprehensive income are as follows:

|  | Cumulative Translation Adjustment |  |  | Unrealized Gain (Loss) on Available-for- Sale Securities |  |  | Accumulated Other Comprehensive Income |
|  | (in thousands) |
Balance as of January 1, 2004 |  | $ | 2,613 |  |  | $ | 66 |  |  | $ | 2,679 |

(t) Segment and Enterprise-Wide Reporting

SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, requires certain financial and supplementary information to be disclosed for each reportable operating segment of an enterprise, as defined. Prior to the fourth quarter of 2005, the Company operated its business in two segments, worldwide diagnostic products and worldwide surgical products. In the fourth quarter of 2005, the Company modified its management structure to establish an international division, managed by a divisional president, as a result of the growth in its international operations and began to operate in three reportable segments: domestic diagnostic products, domestic surgical products and international. During the third quarter of 2006, the Company established the domestic diagnostic products division and domestic surgical products division, each managed by a divisional president. Based on its operating structure, the Company has determined that it has reportable segments which correspond directly to these three divisions. Financial information for the three segments is included below for all periods presented and each segment is described as follows:

Domestic Diagnostic Products—This segment develops and markets the ThinPrep System in the United States primarily for use in diagnostic cytology testing applications focused on women’s health. The ThinPrep System is widely used for cervical cancer screening. The ThinPrep System consists of any one or more of the following: the ThinPrep 2000 Processor, ThinPrep 3000 Processor, ThinPrep Imaging System, and related reagents, filters, and other supplies, such as the ThinPrep Pap Test and the Company’s proprietary ThinPrep PreservCyt Solution.

B-F-37

##### Table of Contents

CYTYC CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

December 31, 2006

Domestic Surgical Products—This segment manufactures the NovaSure System, an innovative endometrial ablation device to treat menorrhagia, or excessive menstrual bleeding, the MammoSite Radiation Therapy System, a device for the treatment of early-stage breast cancer, and the GliaSite Radiation Therapy System for the treatment of malignant brain tumors and, markets these products in the Unites States.

International—This segment markets the Company’s diagnostic and surgical products outside of the United States through the Company’s subsidiaries, branch office and distributors. Products sold by the Company’s international segment are manufactured at domestic and international manufacturing locations.

The Company’s chief decision maker, who is the Chief Executive Officer, regularly evaluates the operating team of each segment on their ability to generate net sales and gross profit. Selling, general and administrative functions, as well as the treasury function, are administered on a global basis and therefore these expenses are recorded where disbursed. As such, the Company does not allocate these expenses across its three segments.

The Company’s operating results, by segment, are as follows:

|  | Years Ended December 31,
|  | 2006 |  | 2005 |  | 2004
|  | (in thousands)
Net sales: |  |  |  |  |  |  |  |  |
Domestic diagnostic products |  | $ | 333,950 |  | $ | 311,318 |  | $ | 289,543
Domestic surgical products |  |  | 206,009 |  |  | 143,870 |  |  | 62,479

Corporate expenses |  |  | 272,396 |  |  | 216,781 |  |  | 177,205
Income from operations |  | $ | 201,670 |  | $ | 184,321 |  | $ | 133,865

SFAS No. 131 also requires that certain enterprise-wide disclosures be made related to products and services, geographic areas and significant customers. During 2006, 2005 and 2004, the Company derived its sales from the following geographies (as a percentage of net sales):

|  | Years Ended December 31,
|  | 2006 |  | 2005 |  | 2004
United States |  | 89% |  | 90% |  | 89%
International |  | 11% |  | 10% |  | 11%
|  | 100% |  | 100% |  | 100%

During the year ended December 31, 2006, no customer represented 10% or more of consolidated net sales. During the years ended December 31, 2005 and 2004, net sales to one customer within the Company’s domestic diagnostic products business represented 11% and 17%, respectively, of consolidated net sales. No other customer represented 10% or more of consolidated net sales during these periods.

(u) Recent Accounting Pronouncements

In June 2006, the FASB issued FIN No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109, which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN No. 48 prescribes a recognition threshold and measurement criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN No. 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition

and defines the criteria that must be met for the benefits of a tax position to be recognized. The cumulative effect of the change in accounting principle must be recorded as an adjustment to opening retained earnings. The Company has completed its initial evaluation of the impact of the January 1, 2007 adoption of FIN No. 48 and determined that such adoption is not expected to have a material impact on its financial statements.

In September 2006, the SEC issued Staff Accounting Bulletin (“SAB”) No. 108, Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements, which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The Company adopted the provisions of SAB No. 108 on December 31, 2006, as required and such adoption did not have any impact on the Company’s financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. Among other requirements, SFAS No. 157 defines fair value and establishes a framework for measuring fair value and also expands disclosure requirements regarding fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those years. The Company is evaluating the impact of adopting SFAS No. 157 on its financial statements.

(4) Acquisition Activity

(a) Acquisition of Helica Instruments Limited

On October 25, 2006, the Company acquired the business of Helica Instruments Limited (“Helica”), net of certain assets. This acquisition included the Helica Thermal Coagulator (“HTC”) System, and all related intellectual property, developed and manufactured by Helica, a privately held company based in Edinburgh, Scotland. The HTC System is used by obstetricians and gynecologists for the treatment of endometriosis. The Company intends to develop a second-generation product for worldwide product launch anticipated to occur in 2008. Under the terms of the agreement, the Company made an up-front cash payment of $1 million to Helica. Within two years, but subject to commercialization by the Company of the second-generation product, the Company will be obligated to pay Helica an additional $2 million (“Commercialization Milestone Payment”). After making the Commercialization Milestone Payment, the Company will be obligated to make contingent earn-out payments tied to future performance milestones. The contingent earn-out payments are based on sales of the second-generation product for the two year period following the Commercialization Milestone Payment and will be recorded as additional goodwill when earned. Total consideration under the agreement will not exceed $9 million. The acquisition was accounted for as a purchase in accordance with SFAS No. 141, Business Combinations, and accordingly, the results of operations of Helica were included in the accompanying consolidated statement of income from the date of the acquisition. The operating results of Helica are not material to any periods presented and accordingly pro forma financial information is not presented.

The aggregate purchase price of approximately $1.3 million, including acquisition costs, was allocated to the estimated fair values of the assets acquired and liabilities assumed, at the date of acquisition. The Company did not acquire any of Helica’s tangible assets. Of the total purchase price, the Company allocated $0.8 million to the acquired patent and developed technology and $0.5 million to goodwill, which is non-deductible for tax purposes.

(b) Acquisition of Proxima

On March 7, 2005, the Company acquired Proxima Therapeutics, Inc. (“Proxima”), a privately held company located in Alpharetta, Georgia, in a non-taxable transaction (the “Merger”). As a result of the Merger, all of Proxima’s fully-diluted equity immediately prior to the Merger was automatically converted into the right to receive an initial cash payment of approximately $160 million, plus contingent earn-out payments tied to future performance milestones. The contingent earn-out payments were based on incremental sales growth in the

breast-related products during 2005 and 2006, were subject to an aggregate cap of $65 million and have been recorded as additional goodwill when earned. As of December 31, 2006, the Company has accrued $3.6 million for contingent earn-out payments relating to 2006 performance milestones that will be paid during the first quarter of 2007. In March 2006, the Company paid $21.1 million for contingent earn-out payments relating to 2005 performance milestones, of which $20.9 million was accrued at December 31, 2005.

The initial purchase price payment was paid with Cytyc’s available cash. Pursuant to the agreement for the Merger, $15.8 million of the purchase price was placed in escrow to satisfy potential claims. During the three months ended March 31, 2006, the Company released the $15.8 million, plus interest, from escrow to the former Proxima shareholders.

The aggregate purchase price for Proxima, including the contingent earn-out payments relating to 2006 and 2005 performance milestones, was $187.8 million, of which $184.7 million represented cash payable to Proxima shareholders and $3.1 million represented acquisition-related fees and expenses. The acquisition was accounted for as a purchase in accordance with SFAS No. 141 and accordingly, the results of operations of Proxima were included in the accompanying consolidated statement of income from the date of the acquisition. The purchase price was supported by estimates of future sales and earnings of Proxima, as well as the value of sales force and other projected synergies.

Purchase Price Allocation

The following table summarizes the fair values of the assets acquired and liabilities assumed at the date of acquisition (“Original Amount”) and includes the contingent earn-out payments relating to 2006 and 2005 performance milestones and subsequent adjustments, for an aggregate purchase price of approximately $187.8 million, including acquisition costs:

|  | Original Amount |  |  | 2005 Contingent Earn-out |  | 2006 Contingent Earn-out |  | 2006 Adjustments |  |  | Amount as of December 31, 2006 |

|  | $ | 163,130 |  |  | $ | 20,906 |  | $ | 3,613 |  | $ | 168 |  |  | $ | 187,817 |

As part of the purchase price allocation, all tangible and intangible assets and liabilities were identified and valued. Of the total purchase price, the Company allocated $2.9 million to acquired net tangible assets. The net deferred tax liability of $14.8 million is primarily comprised of $26.6 million of deferred tax assets, net of a $1.0 million valuation allowance, relating to acquired net operating losses and tax credits and deferred tax liabilities of $39.3 million relating to patents and developed technology. The Company determined the fair value of Proxima’s tangible assets and liabilities based on a review of Proxima’s historical and then current financial statements and an understanding of the ongoing nature of the assets and liabilities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

December 31, 2006

The Company also allocated $101.9 million to the acquired patents and developed technology (primarily associated with the MammoSite Radiation Therapy System (“MammoSite”)). The acquired patents expire at various dates through 2023. Based on the average life of the patent portfolio, the remaining economic life of the developed technology is expected to be approximately 15 years. The Company is amortizing the patents and developed technology over this period using the cash flow method, under which amortization is calculated and recognized based upon the Company’s estimated net cash flows over the life of the intangible asset, reflecting the pattern in which the economic benefits of the intangible asset are consumed in accordance with SFAS No. 142. The Company believes the patents provide sufficient coverage for differentiated products to sustain some competitive advantage in the marketplace over the average remaining life of the patents.

The Company valued the intangible assets acquired, including the portfolio of patents and technologies associated with the MammoSite and GliaSite products, based on present value calculations of income using risk-adjusted cash flows for each product, an analysis of company accomplishments, an assessment of overall contributions, as well as project risks. The projections used in the valuation are based on estimates of relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by the Company and its competitors, as well as estimates of cost of sales, operating expenses, and income taxes resulting from the acquired products. In addition, the projections reflect the Company’s expectation that improvements to the current devices will continue to be made over the life cycle of the product lines. As a result, the completed technology that existed as of the acquisition date was assumed to represent a declining percentage of the devices’ technological composition over time.

The rate utilized to discount the net cash flows to their present value was based on estimated weighted-average cost of capital calculations. A discount rate of 25% was used to value the acquired intangible assets. This discount rate is higher than the Company’s weighted-average cost of capital due to the early-stage life cycle of the acquired products and related inherent uncertainties surrounding the successful commercialization and development of the acquired intangible assets, the useful life of such technology, the profitability levels of such technology, and the uncertainty of technological advances that were unknown at that time.

The projections used to value the tangible assets and liabilities, as well as identifiable intangible assets, reflected no material change in historical pricing, margins or expense levels specifically associated with these acquired net assets. There have been no variations from the Company’s underlying projections and assumptions as compared to actual operating results that would have had a material impact on the valuation.

Goodwill

The excess of the purchase price, including contingent earn-out payments relating to 2006 and 2005 performance milestones, over the fair value of tangible and identifiable intangible net assets was allocated to goodwill, which is non-deductible for tax purposes and totaled $97.8 million. In accordance with SFAS No. 142, this amount will not be systematically amortized. Instead, the Company will perform an annual assessment for impairment by applying a fair-value-based test. As of December 31, 2005, the Company had recorded $97.2 million of goodwill relating to the Proxima acquisition. During 2006, the Company recorded additional goodwill related to the contingent earn-out payments for the 2006 performance milestones, as well as recorded adjustments to goodwill and deferred tax assets of $3.0 million primarily as a result of contingent earn-out payments relating to 2005 performance milestones and the finalization of net operating loss carryforwards.

(c) Acquisition of Novacept

On March 24, 2004, Cytyc acquired Novacept, a privately held California corporation, in a non-taxable transaction. The aggregate purchase price for Novacept was $325.8 million, of which $321.4 million represented cash payable to Novacept shareholders and $4.4 million represented acquisition-related fees and expenses. To satisfy certain claims as provided in the merger agreement, $27.5 million of the purchase price was placed in escrow. The acquisition was accounted for as a purchase in accordance with SFAS No. 141 and accordingly, the results of operations of Novacept were included in the consolidated statement of operations from the date of the acquisition.

Purchase Price Allocation

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed, at the date of acquisition, for an aggregate purchase price of approximately $325.8 million including acquisition costs:

|  | Amount |
|  | (in thousands) |
Current assets |  | $ | 27,418 |
Property and equipment |  |  | 2,556 |
Patents and developed technology |  |  | 83,700 |
Goodwill |  |  | 201,102 |
Net deferred tax asset—long-term |  |  | 1,007 |
Other assets |  |  | 121 |
Current liabilities |  |  | (9,179 | )
In-process research and development |  |  | 19,100 |
|  | $ | 325,825 |

As part of the purchase price allocation, all tangible and intangible assets and liabilities were identified and valued. Of the total purchase price, the Company allocated $20.9 million to acquired net tangible assets. The net deferred tax asset of $1.0 million is primarily comprised of $31.4 million of deferred tax assets, net of a $7.0 million valuation allowance, relating to acquired net operating losses and tax credits and deferred tax liabilities of $32.6 million relating to patents and developed technology. The Company determined the fair value of Novacept’s tangible assets and liabilities based on a review of Novacept’s historical and then current financial statements and an understanding of the ongoing nature of the assets and liabilities.

The Company also allocated $83.7 million to the acquired patents and developed technology. The acquired patents expire at various dates through 2022. Based on the average life of the patent portfolio, the remaining economic life of the developed technology is expected to be approximately 15 years. The Company is amortizing the patents and developed technology over this period using the cash flow method. The Company believes the patents provide sufficient coverage for differentiated products to sustain some competitive advantage in the marketplace over the average remaining life of the patents.

The Company allocated $19.1 million of the purchase price to an in-process research and development project. This allocation represents the estimated fair value based on risk-adjusted cash flows related to the complete and incomplete research and development activities. The incomplete research and development activities primarily were associated with an upgrade to the RF Controller. The RF Controller delivers radio

frequency energy and is one of the two primary components of the NovaSure System. The upgrade to the RF Controller was necessary to replace the existing power supply, a critical component of the RF Controller which was being discontinued by its supplier.

As of the date of acquisition, the upgrade to the RF Controller was under design review, the remaining costs to complete the project were not material and the project was anticipated to be, and actually was, completed in late-2004 with net cash inflows commencing at that time. Accordingly, the acquired in-process research and development was charged to expense as of the date of the acquisition and included in the Company’s statement of income in 2004. Since the acquisition date, there have been no additional significant, ongoing activities associated with the in-process research and development project and there were no other significant acquired projects.

The Company valued the intangible assets acquired, including the portfolio of patents and technologies and the in-process research and development project, based on present value calculations of income using a risk-adjusted cash flow, an analysis of project accomplishments and remaining outstanding items, an assessment of overall contributions, as well as project risks. The value assigned to the in-process research and development project was determined by estimating the costs to develop the acquired technology into a commercially viable product, estimating the net cash flows resulting from the project, and discounting the net cash flows to their present value, as well as determining the importance of the upgraded RF Controller to sustaining uninterrupted sales of the NovaSure System. As of the acquisition date, the remaining costs to complete the project were not material.

The projections used to value the acquired intangible assets and the in-process research and development project were based on estimates of relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by the Company and its competitors, as well as estimates of cost of sales, operating expenses, and income taxes from the acquired products and in-process research and development project. In addition, the projections reflect the Company’s expectation that improvements to the current devices would continue to be made over the life cycle of the product lines. As a result, the completed technology that existed as of the acquisition date was assumed to represent a declining percentage of the devices’ technological composition over time.

The rates utilized to discount the net cash flows to their present value were based on estimated weighted-average cost of capital calculations. Discount rates in the range of 15% to 20% were used to value the acquired intangible assets and the in-process research and development project. The discount rates were higher than the Company’s weighted-average cost of capital due to the early-stage life cycle of the acquired products, the inherent uncertainties surrounding the outcome of the upgrade project and successful commercialization and development of the acquired intangible assets, the useful life of the acquired technology, the profitability levels of such technology and the uncertainty of technological advances that were unknown at that time.

The projections the Company used to value the acquired tangible and intangible assets and liabilities, as well as the in-process research and development project, reflected no material change in historical pricing, margins or expense levels specifically associated with the acquired net assets and the upgrade project. There have been no variations from the Company’s underlying projections and assumptions as compared to actual operating results that would have had a material impact on the valuation of the in-process research and development project.

through 2024 if not utilized. The Company, through its acquisition of Proxima, has net operating losses for federal income tax purposes of approximately $26.8 million at December 31, 2006 that will expire at various dates beginning in 2010 and through 2025 if not utilized. The net operating loss and research and development tax credit carryforwards are subject to review by the Internal Revenue Service. Ownership changes, as defined in the Internal Revenue Code, may limit the amount of these tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value immediately prior to the ownership change.

(7) Indebtedness

(a) Convertible Notes

On March 22, 2004, the Company completed the sale (the “Offering”) of $250 million aggregate principal amount of its 2.25% convertible notes due 2024. Total proceeds from the private placement were $242.3 million, net of debt issuance costs of $7.7 million. The notes bear interest at a rate of 2.25% per year on the principal amount, payable semi-annually in arrears in cash on March 15 and September 15 of each year, beginning September 15, 2004. Beginning in 2009, the Company may owe contingent interest if certain events occur, as defined under the terms of the Offering. The holders of the notes may convert the notes into shares of the Company’s common stock at a conversion price of $29.67 per share, subject to adjustment, prior to the close of business on March 15, 2024, subject to prior redemption or repurchase of the notes, under any of the following circumstances: (1) during any calendar quarter commencing after June 30, 2004 if the closing sale price of the Company’s common stock exceeds 120% of the conversion price for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter (if the specified threshold is met, the notes will thereafter be convertible at any time at the option of the holder prior to the close of business on March 15, 2024); (2) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes for each day of such period was less than 98% of the product of the closing sale price of the Company’s common stock and the number of shares issuable upon conversion of $1,000 principal amount of the notes; (3) if the notes have been called for redemption; or (4) upon the occurrence of specified corporate events.

Holders may require the Company to repurchase the notes on March 15 of 2009, 2014 and 2019 at a repurchase price equal to 100% of their principal amount, plus accrued and unpaid interest, including contingent interest and liquidated damages, if any, to, but excluding, the repurchase date. The Company may redeem any of the notes beginning March 20, 2009, by giving holders at least 30 days’ notice. The Company may redeem the notes either in whole or in part at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest, including contingent interest and liquidated damages, if any, to, but excluding, the redemption date.

The notes will be the Company’s senior unsecured obligations and will rank equally with all of the Company’s existing and future senior unsecured debt and prior to all future subordinated debt. The notes will be effectively subordinated to any future secured indebtedness to the extent of the collateral securing such indebtedness, and to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

(b) Credit Agreement

On June 30, 2006, the Company entered into a five-year Credit Agreement (the “Credit Agreement”) with a syndicate of five lenders. The Credit Agreement provided for a $150 million senior unsecured revolving credit

December 31, 2006

facility. On October 6, 2006, the Company and its related lenders amended the Credit Agreement in order to, among other items, increase the committed amount of the revolving credit facility to $345 million and to include one additional lender into the syndicate of lenders. The Company may request an increase in available borrowings under the Credit Agreement by an additional amount of up to $155 million (for a maximum amount of $500 million) upon satisfaction of certain conditions. These increased borrowings may be provided either by one or more existing lenders upon the Company obtaining the agreement of such lender(s) to increase commitments or by new lenders being added to the credit facility. The loan proceeds are available to be used by the Company and its subsidiaries to finance working capital needs and for general corporate purposes, including certain permitted business acquisitions. Four of the Company’s wholly-owned subsidiaries are guarantors under the Credit Agreement.

Amounts under the Credit Agreement may be borrowed, repaid and re-borrowed by the Company from time to time until the maturity of the Credit Agreement on June 30, 2011. Voluntary prepayments and commitment reductions requested by the Company under the Credit Agreement are permitted at any time without penalty (other than customary breakage costs relating to the prepayment of any drawn loans) upon proper notice and subject to a minimum dollar requirement. Borrowings under the Credit Agreement bear interest at a floating rate, which will be, at the Company’s option, either LIBOR plus an applicable margin (which is subject to adjustment based on financial ratios), or a base rate.

The Credit Agreement requires the Company to comply with maximum leverage and minimum fixed charge coverage ratios. The Credit Agreement contains affirmative and negative covenants, including limitations on additional debt, liens, certain investments, and acquisitions outside of the healthcare business. The Credit Agreement also includes events of default customary for facilities of this type. Upon the occurrence of an event of default, all outstanding loans may be accelerated and/or the lenders’ commitments terminated.

As of December 31, 2006, the Company had no balance outstanding under this Credit Agreement.

(c) Finance Lease Obligation

On July 11, 2006, the Company signed a non-cancelable lease agreement for a building with approximately 146,000 square feet located in Marlborough, Massachusetts, to be principally used as an additional manufacturing facility. In 2011, the Company will have an option to lease an additional 30,000 square feet. As part of the lease agreement, the lessor agreed to allow the Company to make significant renovations to the facility to prepare the facility for the Company’s manufacturing needs. The Company is responsible for a significant amount of the construction costs and therefore was deemed under generally accepted accounting principles to be the owner of the building during the construction period, in accordance with EITF No. 97-10. During the third quarter of 2006, the Company recorded the fair market value of the facility of $13.2 million within property and equipment on its consolidated balance sheet, with an offsetting increase to accrued expenses and other non-current liabilities. The Company plans to begin occupying the facility during the first half of 2007. During the construction period, the Company is capitalizing the interest expense related to the lease obligation and amounts to be paid for construction are being recorded as construction in progress until construction is complete. As of December 31, 2006, the Company recorded $1.5 million as construction in progress related to this facility, including interest of $0.6 million.

At the completion of the construction period, the Company will review the lease for potential sale-leaseback treatment in accordance with SFAS No. 98, Accounting for Leases: Sale-Leaseback Transactions Involving Real Estate, Sales-Type Leases of Real Estate, Definition of the Lease Term, and Initial Direct Costs of Direct

Financing Leases—an amendment of FASB Statements No. 13, 66, and 91 and a rescission of FASB Statement No. 26 and Technical Bulletin No. 79-11. However, based on its preliminary analysis, the Company determined that the lease will not qualify for sale-leaseback treatment. Therefore, the building, improvements and associated liabilities will remain on the Company’s financial statements throughout the lease term. The building and tenant improvements will be depreciated on a straight line basis over their estimated useful lives.

The term of the lease is for a period of approximately 12 years commencing on November 14, 2006.

Future minimum annual lease payments, including principal and interest, under this lease are as follows:

|  | Amount
|  | (in thousands)
2007 |  | $ | 588
2008 |  |  | 924
2009 |  |  | 939
2010 |  |  | 982
2011 |  |  | 982
Thereafter |  |  | 7,913
Total minimum lease payments |  |  | 12,328
Less—amount representing interest |  |  | 5,805
|  | $ | 6,523

There were no payments under this lease during 2006.

(8) Stockholders’ Equity

(a) Common Stock Reserved

As of December 31, 2006, the Company has reserved common stock for issuance as follows (in thousands):

|  | Number of Shares
Employee and Director stock incentive plans |  | 20,684
Employee stock purchase plan |  | 1,684
Convertible debt |  | 8,426
|  | 30,794

(b) Stock Repurchase Program

Under the current stock repurchase program, which was approved by the Company’s Board of Directors during the fourth quarter of 2005, the Company is authorized to repurchase up to $200 million of its common stock through open market purchases or private transactions that will be made from time to time as market conditions allow. The stock repurchase program is expected to be in effect until November 15, 2009. Shares repurchased under this program will be held in the Company’s treasury. The stock repurchase program may be suspended or discontinued at any time without prior notice. During 2006 and 2005, the Company repurchased 4,109,322 and 2,190,851 shares, respectively, with an aggregate cost of $108.6 million and $50.1 million, respectively. All of these shares are held in treasury.

(c) Preferred Stock

The Company’s charter authorizes 5,000,000 shares of $0.01 par value Preferred Stock, none of which was outstanding during the years ended December 31, 2006 and 2005. The Board of Directors has designated 200,000 shares of preferred stock as the Company’s Series A Junior Participating preferred stock. The Board of Directors has the authority to issue such shares in one or more series and to fix the relative rights and preferences without further vote or action by the stockholders.

(d) Stockholders’ Rights Plan

On August 6, 1997 the Board of Directors declared a dividend of one Preferred Stock purchase right for each outstanding share of the Company’s common stock to stockholders of record at the close of business on September 5, 1997. Each right entitles the holder to purchase from the Company a unit consisting of one one-hundredth of a share of Series A Junior Participating Preferred Stock, $0.01 par value, at a purchase price of $110 per unit, subject to adjustment. The rights are not exercisable or transferable apart from the common stock until: (a) 10 days after the public announcement that a person or group (an “Acquiring Person”) has acquired 15% or more of the Company’s common stock; (b) 10 business days after the commencement of, or the first public announcement of the intention to commence, a tender offer which would increase the beneficial ownership of a person or group to 15% or more of the Company’s common stock; or (c) 10 business days after the determination by the Company’s board of directors that a person is an Adverse Person. After any person or group has become an Acquiring Person or Adverse Person, except as provided in the Rights Agreement and amendments thereto (the “Rights Agreement”), each right entitles the holder (other than the Acquiring Person or the Adverse Person) to purchase, at the exercise price, that number of shares of common stock of the Company having a market price of two times the exercise price. If the Company is acquired in a merger or other business combination transaction, except as provided in the Rights Agreement, each exercisable right entitles the holder (other than the Acquiring Person or the Adverse Person) to purchase, at the exercise price, that number of shares of common stock of the acquiring company having a market price of two times the exercise price of the right.

The Board of Directors may redeem the rights for $0.01 per right at any time before the tenth day following the public announcement by either the Company or an Acquiring Person that a person or group has become an Acquiring Person. However, the rights may not be redeemed if the Board of Directors of the Company determines that a person or group has become an Adverse Person. The rights expire on September 5, 2007.

(9) Stock-Based Compensation and Stock Ownership Plans

(a) Stock-Based Compensation

In December 2004, FASB issued SFAS No. 123R, which requires all stock-based compensation to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The Company adopted SFAS No. 123R on January 1, 2006 using the modified prospective method and accordingly, prior period amounts have not been restated. In order to determine the fair value of stock options and employee stock purchase plan shares, the Company is using the Black-Scholes option pricing model and is applying the multiple-option valuation approach to the stock option valuation. The Company is recognizing stock-based compensation expense on a straight-line basis over the requisite service period of the awards for options granted following the adoption of SFAS No. 123R. For unvested stock options outstanding as of January 1, 2006, the Company will continue to recognize stock-based compensation expense using the accelerated amortization method prescribed in FIN No. 28.

B-F-51

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

December 31, 2006

Estimates of the fair value of future equity awards will be affected by the future market price of the Company’s common stock, as well as the actual results of certain assumptions used to value the equity awards. These assumptions include, but are not limited to, the expected volatility of the common stock, the number of stock options to be forfeited and exercised by employees, and the expected term of options granted.

As noted above, the fair value of stock options and employee stock purchase plan shares is determined by using the Black-Scholes option pricing model and applying the multiple-option valuation approach to the stock option valuation. The options have graded-vesting on an annual basis over an average vesting period of four years. In applying the multiple-option approach, each option “tranche” is separately valued based upon when the tranche vests. The Company estimates the expected option term by calculating the average period of time before the employees exercise their options and adds this to the vesting period of each tranche. Historically, this period of time has averaged one year from the date the options vest. The expected term of employee stock purchase plan shares is the average of the remaining purchase periods under each offering period. For equity awards granted prior to the adoption of SFAS No. 123R, the volatility of the common stock was estimated using historical volatility. For equity awards granted since January 1, 2006, the volatility of the common stock is estimated using a combination of historical and implied volatility, as discussed in SAB No. 107. By using this combination, the Company is taking into consideration the historical realized volatility, as well as factoring in estimates of future volatility that the Company believes will differ from historical volatility as a result of the Company’s product diversification over the last two years, the market performance of the common stock, the volume of activity of the underlying shares, the availability of actively traded common stock options, and overall market conditions.

The risk-free interest rate used in the Black-Scholes option pricing model is determined by looking at historical U.S. Treasury zero-coupon bond issues with remaining terms equal to the expected terms of the equity awards. In addition, an expected dividend yield of zero is used in the option valuation model, because the Company does not expect to pay any cash dividends in the foreseeable future. Lastly, in accordance with SFAS No. 123R, the Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. In order to determine an estimated pre-vesting option forfeiture rate, the Company used historical forfeiture data. This estimated forfeiture rate has been applied to all unvested options outstanding as of January 1, 2006 and to all options granted since January 1, 2006. Therefore, stock-based compensation expense is recorded only for those options that are expected to vest.

The income statement classification of the Company’s stock-based compensation is consistent with the classification of the Company’s cash compensation expense related to the salaries of the employee option holders. Total stock-based compensation recognized in the Company’s consolidated statement of income for the year ended December 31, 2006 is as follows:

|  | Amount
|  | (in thousands)
Cost of sales |  | $ | 1,268
Research and development |  |  | 2,959
Sales and marketing |  |  | 9,301
General and administrative |  |  | 7,610
Total stock-based compensation expense |  | $ | 21,138

The tax benefit and deferred tax assets related to the $21.1 million of stock-based compensation expense recorded during the year ended December 31, 2006 were $6.1 million and $5.9 million, respectively.

The adoption of SFAS No. 123R in 2006 resulted in a $(0.13) and $(0.10) reduction of the Company’s basic and diluted earnings per share, respectively.

Prior to January 1, 2006, the Company accounted for stock options using the intrinsic value method, pursuant to the provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees. Under this method, stock-based compensation expense was measured as the difference between the option’s exercise price and the market price of the Company’s common stock on the date of grant. Historically, under this method, the Company had no stock-based compensation from options granted to employees because stock options are granted at the market price of the common stock on the date of grant. However, as discussed further in Note 15, to correct errors related to stock-based compensation not previously recorded for certain stock options as a result of certain stock option exercise activities, the Company has restated its consolidated financial statements by recording an increase in additional paid-in capital and a decrease in retained earnings of $28.6 million as of January 1, 2004, reflecting the cumulative impact to net (loss) income in the years ended December 31, 1996 to December 31, 2002. While the errors had no effect on the statements of income or statements of cash flows for the years ended December 31, 2004, 2005 or 2006, they did have an effect on the calculation of stock-based compensation as would have been reported had the Company adopted SFAS No. 123.

Had the Company accounted for stock awards pursuant to the provisions of SFAS No. 123, Accounting for Stock-Based Compensation, net income and net income per share would have been as follows for the years ended December 31, 2005 and 2004, respectively (as restated — see Note 15):

|  | 2005 |  |  | 2004 |

Prior to the adoption of SFAS No. 123R, the Company presented all tax benefits for deductions resulting from the exercise of stock options and disqualifying dispositions as operating cash flows in the consolidated statement of cash flows. SFAS No. 123R generally requires the benefits of tax deductions in excess of recognized compensation expense to be reported within cash flows from financing activities.

As of December 31, 2006, total unrecognized stock-based compensation expense relating to unvested employee stock awards, adjusted for estimated forfeitures, was $29.1 million. This amount is expected to be recognized over a weighted-average period of 3.0 years. If actual forfeitures differ from current estimates, total unrecognized stock-based compensation expense will be adjusted for future changes in estimated forfeitures.

(b) Employee and Director Stock Incentive Plans

The Cytyc Corporation 2004 Omnibus Stock Plan (the “2004 Omnibus Plan”), which is the Company’s primary plan for grants of equity, provides for the issuance of up to 12,250,000 shares of the Company’s common stock, no more than 8,200,000 of which shares may be issued as awards other than stock options or stock appreciation rights. The 2004 Omnibus Plan provides for grant of various incentives, including stock options and other stock-based awards. At December 31, 2006, 4,929,238 shares were available for future grant under the 2004 Omnibus Plan. Prior to the approval of the 2004 Omnibus Plan, the Company had various employee and director equity compensation plans, including the 1998 Stock Plan, the 1995 Stock Plan, the 1995 Non-Employee Director Stock Option Plan and the 2001 Non-Employee Director Stock Option Plan. These plans were terminated with the adoption of the 2004 Omnibus Plan and although awards are still outstanding under these plans, no further awards may be issued under these plans.

The following table summarizes options outstanding, by stock plan, as of December 31, 2006:

2004 Omnibus Plan |  | 7,074,661

The aggregate intrinsic value of dilutive options outstanding and options exercisable as of December 31, 2006 was $118.1 million and $86.4 million, respectively. The intrinsic value is calculated as the difference between the market value of the Company’s common stock as of December 31, 2006 and the exercise price per share. The market value as of December 31, 2006 was $28.30 per share as quoted on The NASDAQ National Market.

(c) Employee Stock Purchase Plan

During the first half of 2004, the Board of Directors and the stockholders of the Company approved the 2004 Employee Stock Purchase Plan, pursuant to which 2,000,000 shares of common stock may be issued. As a result, the 1995 Employee Stock Purchase Plan, which existed at that time, terminated effective November 30, 2004. The purchase price under the 2004 Employee Stock Purchase Plan is determined by taking the lesser of 85% of the closing price on the first or last day of the period. During 2006, 169,520 shares of common stock were issued at purchase prices of $22.34 and $22.12 per share. At December 31, 2006, 1,683,925 shares were available for future issuance under the 2004 Employee Stock Purchase Plan. During 2005, 146,555 shares of common stock were issued at purchase prices of $19.90 and $20.17 per share. During 2004, 128,687 shares of common stock were issued under the 1995 Employee Stock Purchase Plan at purchase prices of $19.00 and $11.25 per share.

In 2006, pursuant to the Company’s adoption of SFAS No. 123R on January 1, 2006, the Company recorded $0.9 million of stock-based compensation expense equal to the fair value of the shares purchased under the 2004 Employee Stock Purchase Plan during 2006, as a result of the discounted purchase price of the common stock as compared to its fair value on date of grant.

(10) Commitments and Contingencies

(a) Lease Commitments

The Company leases its facilities and certain automobiles and office equipment under non-cancelable operating leases which have expiration dates ranging from 2007 through 2018. Many of the leases have lease renewal dates ranging from one to three years. Future minimum annual lease payments under these leases are as follows:

|  | Amount
|  | (in thousands)
2007 |  | $ | 8,960
2008 |  |  | 9,249
2009 |  |  | 9,045
2010 |  |  | 8,724
2011 |  |  | 8,812
Thereafter |  |  | 40,040
|  | $ | 84,830

Rent expense under operating leases totaled approximately $6.7 million, $6.8 million and $4.0 million in 2006, 2005 and 2004, respectively.

(b) Long-Term Supply Contracts

For reasons of quality assurance, sole source availability or cost effectiveness, certain key components and raw materials are available only from a sole supplier. Working closely with its suppliers, the Company has entered into certain long-term supply contracts to assure continuity of supply while maintaining high quality and reliability. In certain of these contracts, a minimum purchase commitment has been established.

As part of the acquisition of Proxima in March 2005, the Company assumed a non-cancelable supply agreement with one of its vendors to provide the facility for the production of one of its products and its ongoing exclusive supply. The initial term of the agreement expires in 2008 and is subject to annual indexed price adjustments. As of December 31, 2006, the minimum annual commitments under the agreement are $1 million in each year through 2008.

Future supply commitments under the Company’s long-term supply contracts are as follows:

|  | Amount
|  | (in thousands)
2007 |  | $ | 4,011
2008 |  |  | 4,000
2009 |  |  | 3,000
2010 |  |  | 3,000
2011 |  |  | 3,000
Thereafter |  |  | 3,000
|  | $ | 20,011

Payments under these contracts totaled approximately $4.9 million, $5.5 million and $8.0 million in 2006, 2005 and 2004, respectively.

(c) Royalties and Contingent Earn-Out Payments

The Company is the exclusive licensee of certain patented technology used in the ThinPrep System, NovaSure System, and the GliaSite System. In connection with these licenses, royalty expense totaled $5.0 million, $4.3 million and $1.7 million for the years ended December 31, 2006, 2005 and 2004, respectively.

Part of the purchase price for Proxima includes contingent earn-out payments tied to future performance milestones (see Note 4(b)). At December 31, 2006, $3.6 million was accrued for the contingent earn-out payments relating to incremental sales growth in the breast-related products during 2006.

Part of the purchase price for Helica includes payments within two years, subject to commercialization by the Company of the second-generation product and contingent earn-out payments tied to future performance milestones (see Note 4(a)). At December 31, 2006 no amounts were due under this agreement.

(d) Private Equity Investment

During the third quarter of 2005, the Company entered into a $5 million private equity investment commitment which may be paid over the succeeding three years. As of December 31, 2006, $1.6 million of this commitment was paid, which is recorded in Other Assets (see Note 2(j)).

(e) Litigation

On November 17, 2003, DEKA Products Limited Partnership (“DEKA”) initiated arbitration proceedings against Cytyc alleging that Cytyc underpaid royalties due to DEKA pursuant to a cross-license agreement entered into in 1993 (the “1993 DEKA Agreement”). The dispute concerned the method of calculating royalties on the sale of the single use disposable ThinPrep Pap Test kit. In March 2005, the arbitration panel issued a partial final award in which it agreed with DEKA’s interpretation of the 1993 DEKA Agreement and on April 26, 2005, issued its final decision which Cytyc appealed. Cytyc recorded a pre-tax charge in the first quarter of 2005 in the amount of $7.8 million, which was in addition to the $1.3 million previously recorded. Subsequently, each month, Cytyc recorded an accrual for the difference between the quarterly payments to DEKA and the amounts calculated pursuant to the arbitration panel decision. As a result of a final decision of the United States Court of Appeals for the First Circuit in February 2006, the Company paid DEKA $11.4 million. Prospectively, the Company will pay DEKA a one percent royalty on applicable net sales of ThinPrep Pap Test disposable components; however, this royalty is not expected to be material to the Company’s future operating results or financial position.

On June 16, 2003, Cytyc filed a suit for Declaratory Judgment in United States District Court for the District of Massachusetts asking the court to determine and declare that certain of TriPath Imaging, Inc.’s (“TriPath”) patents are invalid and not infringed by the Company’s ThinPrep Imaging System. On June 17, 2003, TriPath announced that it had filed a lawsuit against the Company in the United States District Court for the Middle District of North Carolina alleging patent infringement, false advertising, defamation, intentional interference, unfair competition, and unfair and deceptive trade practices. The non-patent claims have been dismissed and the patent cases have since been consolidated into a single action. A hearing occurred on August 2, 2006 in the United States District Court for the District of Massachusetts to hear oral arguments on summary judgment motions. A trial is expected to occur during April 2007. The Company continues to believe that the claims against it are without merit and intends to vigorously defend this suit. Given the stage and current status of the litigation, the Company is unable to reasonably estimate the ultimate outcome of this case.

The Company is also involved in ordinary, routine litigation incidental to its business. Although the outcomes of these other lawsuits and claims are uncertain, management does not believe that, individually or in the aggregate, these other lawsuits and claims will have a material adverse effect on the Company’s business, financial condition, results of operations or liquidity.

(11) Restructuring

During the fourth quarter of 2006, Company management approved restructuring plans designed to reduce future operating expenses by consolidating the Company’s Mountain View, California operations into its existing operations in Costa Rica and Massachusetts. In connection with this plan and pursuant to SFAS No. 146, the Company incurred $2.9 million of restructuring costs during the fourth quarter of 2006 related to severance and included such costs within operating expenses in the consolidated statement of income. The Company expects to incur additional restructuring costs in 2007 of approximately $5 million to $6 million, primarily resulting from retention costs and incremental depreciation of leasehold improvements. None of the severance has been paid as of December 31, 2006 and all is expected to be paid during 2007.

(12) Employee Benefit Plan

The Company maintains an employee benefit plan under Section 401(k) of the Internal Revenue Code. The plan allows for employees to defer a portion of their salary up to the maximum allowed under IRS rules. The Company made contributions to the plan totaling $2.7 million, $2.0 million and $1.9 million related to the years ended December 31, 2006, 2005 and 2004, respectively.

(2) | The Company recorded a gain on the sale of its Vision shares of $13.1 million, including a realized foreign currency gain of $1.9 million during 2006, during the fourth quarter of 2006 (See Note 4(d)). The tax effect related to this gain was $4.6 million.

(3) | The Company recorded a pre-tax charge of $7.8 million in the first quarter of 2005 in connection with the DEKA Products Limited Partnership arbitration panel decision (see Note 10(e)).

(14) Subsequent Events

On February 11, 2007, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Augusta Medical Corporation, a Delaware corporation and a newly-formed wholly-owned subsidiary of Cytyc (the “Purchaser”), and Adeza Biomedical Corporation, a Delaware corporation (“Adeza”). Pursuant to the Merger Agreement, the Purchaser will commence a cash tender offer (within 10 business days) to purchase all outstanding shares of Adeza’s common stock (the “Shares”) in exchange for $24.00 per share in cash (the “Offer Price”). Subsequent to the successful completion of the tender offer and the satisfaction or waiver of the conditions set forth in the Merger Agreement, the Purchaser will be merged with and into Adeza (the “Adeza Merger”), with Adeza continuing as the surviving corporation and as a wholly-owned subsidiary of Cytyc. At the effective time of the Adeza Merger, each Share of Adeza then outstanding (other than certain shares, as defined in the Merger Agreement) will be converted into the right to receive in the Adeza Merger the same $24.00 per share cash Offer Price, without interest. Any options to purchase the Shares that remain outstanding immediately prior to the Adeza Merger will be entitled to an amount in cash equal to the excess, if any, of the Offer Price over the per Share exercise price of such option, multiplied by the number of unexercised Shares subject to the option.

The purchase price of $452 million will be paid out of Cytyc’s existing cash, the cash on Adeza’s balance sheet, and the Company’s existing credit facility. The acquisition will be accounted for as a purchase in accordance with SFAS No. 141.

On February 26, 2007, the Company entered into a definitive agreement (“Definitive Agreement”) with Adiana, Inc. (“Adiana”), a privately-held company, to acquire the outstanding shares of Adiana. All of Adiana’s fully-diluted equity immediately prior to the close of the acquisition (expected to occur March 2007), will automatically convert into the right to receive an initial cash payment of $60 million, plus milestone payments. The milestone payments include (i) payment of up to $25 million tied to potential FDA regulatory approval of the Adiana permanent contraception product and (ii) contingent payments tied to future revenue performance milestones. The contingent payments are based on incremental sales growth of the Adiana permanent contraception product during the four-year period following FDA approval of the Adiana permanent contraception product and are subject to an aggregate cap of $130 million. No payments can be earned after December 31, 2012. According to the terms of the Definitive Agreement, total payments, including the potential FDA milestone payment and the four-year contingent payments, will not exceed $215 million.

The purchase will be funded out of the Company’s existing cash and credit facility. The acquisition will be accounted for as a purchase in accordance with SFAS No. 141.

(15) Restatement of Consolidated Financial Statements

Subsequent to the issuance of the Company’s 2006 consolidated financial statements, the Company determined that previously issued financial statements should be restated to correct certain errors related to charges for stock-based compensation expense not previously recorded for certain stock options as a result of

B-F-60

##### Table of Contents

CYTYC CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—Continued

December 31, 2006

certain stock option exercise activities. As a result, the Company has restated the accompanying consolidated financial statements to record an increase to additional paid-in capital and decrease to retained earnings to correct these errors.

During the first quarter of 2007, the Company became aware of a report prepared by an independent equity research firm suggesting that the Company was at an elevated risk for issues with the dating of stock option exercises prior to the effective date of the Sarbanes-Oxley Act of 2002. At the request of the General Counsel and the Chief Executive Officer, the Audit Committee (the “Audit Committee”) of the Company’s Board of Directors, with the assistance of independent outside counsel and the Company’s internal audit department, conducted a voluntary review of circumstances relating to the exercising of employee stock options. As a result of that review, the Audit Committee concluded with respect to two current executives — the Chief Executive Officer and the General Counsel — that on several occasions during the period from 1996 through 2002, qualified incentive stock options granted under the Company’s stock option plans (the “Plans”) were reported as having been exercised before all of the actions required by the Plan to effect such an exercise were completed. To the extent an exercise can be reported as occurring before all the required actions are complete, an option holder has the opportunity to obtain an exercise date using hindsight (i.e., “exercise back-dating”) and thereby exercise on a date with a preferable market price.

The Company determined that all stock options granted to the Chief Executive Officer and General Counsel and still outstanding at any date following the first in a series of exercises by each of these executives reported as occurring before all the required actions were completed during the period 1996 through August 28, 2002 (the date the look-back practice was no longer available based on the change in the SEC’s filing requirements reducing the reporting window for equity share activity) are subject to variable award accounting because the exercise price of those options was not fixed on the date of grant. The Company has determined variable award accounting is appropriate for these awards because there was a pattern in which the Chief Executive Officer and General Counsel received an exercise date with a more favorable market price as a result of the look-back. This pattern of exercise back-dating, when combined with the right to utilize a stock swap as consideration for the exercise, gave these individuals the ability to alter the exercise price of the options being exercised, resulting in an indirect reduction in the exercise price of the stock options by an amount that was unknown at the date of grant. Accordingly, the Company has recorded stock-based compensation expense (benefit) for each of the years ended December 31, 1996 through 2002 applying variable award accounting, which is based on the excess of the quoted market price of the Company’s common stock at the end of each period over the option exercise price for those options. Based on the Company’s review of the facts and circumstances, the Company concluded that the practice of exercise back-dating for these individuals ended in 2002 and therefore the terms of all outstanding awards became fixed at that time. As a result of a decline in the Company’s stock price during 2002, there was no intrinsic value of the awards at August 28, 2002, the date on which the terms of the awards became fixed.

The Company has analyzed the circumstances surrounding exercises by other executives and other non-officer employees for purposes of determining whether any of the exercise activity under review would result in accounting consequences. Based on this analysis, the Company concluded that single stock option grants to one current and one former executive (the “Two Other Executives”) were modified on the date of exercise in 2000 to allow for exercise back-dating. A pattern was not evident for the Two Other Executives and therefore the Company has concluded that the terms of all other awards granted for the Two Other Executives were fixed as of the grant date. As a result, the Company has recorded a stock-based compensation charge during the year ended December 31, 2000, based on the excess of the quoted market price of the Company’s common stock as of the modification date over the option exercise price for those options.

The cumulative impact to net (loss) income for the years ended December 31, 1996 through 2003 of $28.6 million is reflected as an increase to additional paid-in capital and a decrease to retained earnings as of January 1, 2004. There was no impact to the consolidated statements of income or statements of cash flows for the years ended December 31, 2004, 2005 or 2006. There was no income tax expense (benefit) related to the restatement prior to the year ended December 31, 2001 as the Company had a full valuation allowance recorded against its net deferred tax assets until 2001 due to the uncertainty relating to the future utilization of these deferred tax assets during those periods. In 2001, the Company reversed the valuation allowance against its deferred tax assets and as a result, the deferred tax assets recorded from 1996 through 2001 relating to the stock-based compensation expense discussed above resulted in a $7.0 million benefit in the Company’s consolidated statement of income during the year ended December 31, 2001.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Adeza Biomedical Corporation

We have audited the accompanying balance sheets of Adeza Biomedical Corporation as of December 31, 2006 and 2005, and the related statements of income, convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Adeza Biomedical Corporation at December 31, 2006 and 2005, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 6 to the consolidated financial statements, in fiscal year 2006 Adeza Biomedical Corporation changed its method of accounting for share-based payments.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Adeza Biomedical Corporation’s internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 12, 2007 expressed an unqualified opinion thereon.

ADEZA BIOMEDICAL CORPORATION

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Business

Adeza Biomedical Corporation (“Adeza” or the “Company”) is a Delaware corporation which was originally incorporated in the state of California on January 3, 1985 and reincorporated in Delaware in 1996. Adeza is engaged in the design, development, manufacturing, sales, and marketing of products for women’s health markets worldwide. The Company’s initial focus is on reproductive healthcare, using its proprietary technologies to predict preterm birth and assess infertility. The Company’s products consist of:

| • |  | The TLi(IQ) System and FullTerm, The Fetal Fibronectin Test, which are used to assess the risk of preterm birth in pregnant women.

| • |  | The E-tegrity Test, which is used to determine the feasibility of embryo implantation in patients with infertility who are candidates for in vitro fertilization (“IVF”).

All of the Company’s assets are located in the U.S.

The Company entered into a Merger Agreement with Cytyc and Augusta Medical Corporation on February 11, 2007 whereby Augusta Medical Corporation commenced a tender offer to purchase all of the outstanding shares of the Company’s common stock at a price of $24.00 per share. Following the completion of the tender offer, which is scheduled to expire at 12:00 midnight, New York City time, on March 16, 2007, subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement and in accordance with the relevant portions of the Delaware General Corporation Law (the “DGCL”), it is anticipated that Augusta Medical Corporation will be merged with and into Adeza with Adeza as the surviving corporation, whereby each issued and outstanding share of our common stock not directly or indirectly owned by Cytyc, Augusta Medical Corporation or Adeza will be converted into the right to receive the offer price of $24.00 per share. The purchase price is expected to be approximately $450 million, which will be paid by Cytyc at closing in cash. The acquisition is expected to close in the first half of 2007 and possibly as early as the end of March 2007.

A number of factors could prevent the Company from completing the merger with Cytyc, including but not limited to the failure to satisfy the conditions set forth in the Merger Agreement. If the Company does not complete the proposed merger with Cytyc for any reason, the Company’s business may be negatively impacted due to (i) the payment of a $13.35 million termination fee to Cytyc upon certain circumstances; (ii) the diversion of the Company’s management’s focus toward the proposed merger rather than its core business and other potential business opportunities; (iii) a change in the price of the Company’s common stock to the extent that the current market price reflects an assumption that the proposed merger will be completed; (iv) uncertainty about the effect of the termination of the proposed merger upon the Company’s employees and customers; and (v) negative publicity and/or negative impression of the Company in the investment community.

In connection with the proposed merger, the Company has incurred and will continue to incur certain expenses, including fees and/or expenses of its legal, accounting and financial advisors. Even if the Company does not complete the proposed merger, it must pay for services rendered by these advisors, which total approximately $1.5 million as of February 28, 2007. The Company’s discussion below assumes that it will continue forward as a separate corporate entity. If the proposed merger is consummated, the Company will be operated as a wholly owned subsidiary of Cytyc, and some of the Company’s expenses may be reduced through integration of the operations of both companies.

NOTES TO FINANCIAL STATEMENTS—(Continued)

Basis of Presentation

The Company operates in one business segment, women’s health products. In the year ended December 31, 2006, the Company reported shipping costs billed to its customers as product sales and the related expense as cost of products sold. In the years ended December 31, 2005 and 2004, the Company reported $0.2 million and $0.1 million, respectively, in net shipping costs as cost of products sold.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue Recognition

Revenue from product sales is recognized when there is persuasive evidence an arrangement exists, delivery to the customer has occurred, the price is fixed or determinable and collectibility is reasonably assured. Revenue from laboratory services is recognized as tests are performed.

Effective July 1, 2002, the Company entered into a services agreement with a national laboratory that performed diagnostic tests. Under the terms of the agreement, the laboratory provided certain domestic product distribution and testing services for the Company. Through September 30, 2005, the Company recognized revenue upon the shipment of products to the end user from the national laboratory as the title, risks and rewards of ownership of the products pass from the Company to the end user at that time. On October 1, 2005, the Company discontinued using this national laboratory for fulfillment purposes and the Company began to recognize revenue upon shipment of our products from the Company’s manufacturing facilities.

During 2006, revenue on the Company’s product sales was recognized upon shipment to distributors or customers as the title, risks, and rewards of ownership of the products pass to the distributors or customers, and the selling price of the Company’s products was fixed and determinable at that point. Any advance payments received in excess of revenue recognized are classified as deferred revenue on the accompanying balance sheets. Customers have the right to return products that are defective. There are no other return rights.

During the years ended December 31, 2006, 2005 and 2004, 97%, 98%, and 97%, respectively, of the Company’s product revenues were derived from customers located in the US. Our product sales are derived primarily from the sale of our disposable Fetal Fibronectin Test cassettes.

Warranty Policy

The Company records a liability for product warranty obligations at the time of sale based upon historical warranty experience. The term of the warranty is generally twelve months. The Company also records any additional liability required for specific warranty matters when they become known and are reasonably estimable. The Company’s product warranty obligations are included in other accrued liabilities as follows (in thousands):

|  | Year Ended December 31, |
|  | 2006 |  |  | 2005 |
Balance at beginning of year |  | $ | 30 |  |  | $ | 31 |
Charges to cost of product sales |  |  | 36 |  |  |  | 30 |
Warranty costs incurred |  |  | (32 | ) |  |  | (34 | )
Change in estimate related to accrued warranty costs |  |  | 5 |  |  |  | 3 |

Research and Development

Research and development expenses consist of costs incurred for Company-sponsored research and development activities. These costs include direct and research-related allocated overhead expenses such as facilities costs, salaries and benefits, and material and supply costs in addition to costs associated with clinical trials. The Company expenses research and development costs as such costs are incurred.

Concentrations of Risk

Cash, cash equivalents, short-term investments and accounts receivable are financial instruments which potentially subject Adeza to concentrations of credit risk. Adeza primarily invests in money market funds, and, by policy, limits the amount in any one type of investment, other than securities issued or guaranteed by the U.S. government. Adeza has not experienced any material credit losses and does not generally require collateral on receivables. For the year ended December 31, 2006 and 2005, no single customer represented greater than 5% of total revenues.

Cash Equivalents and Short-Term Investments

Cash equivalents consist of highly liquid financial instruments with original maturities of three months or less at the time of purchase. Short-term investments consist of financial instruments with original maturities ranging from 91 days to less than one year. Cash equivalents and short-term investments consist of commercial paper, corporate debt and money market funds held by a high-credit quality financial institution. Short-term investments are comprised of available-for-sale securities, which are carried at fair value, based on quoted market prices. Unrealized gains (losses) on available-for-sale securities are reflected as a component of accumulated other comprehensive income within shareholders’ equity.

Available-for-sale securities had maturities of less than one year and consisted of the following:

|  | Cost |  | Gross Unrealized Gains |  | Estimated Fair Value
|  | (In thousands)

Depreciation is calculated using the straight-line method, and the cost is amortized over the estimated useful lives of the assets, generally three to seven years. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the assets or the term of the lease, whichever is shorter.

Intangible Assets

Intangible assets are comprised entirely of purchased patents. The following table sets forth the carrying amount of amortizable intangible assets (in thousands):

|  | As of December 31, 2006 |  |  | As of December 31, 2005 |
Gross carrying amount |  | $ | 240 |  |  | $ | 240 |
Less: accumulated amortization |  |  | (160 | ) |  |  | (112 | )
Net carrying amount |  | $ | 80 |  |  | $ | 128 |

Intangible assets are amortized on a straight line basis over their estimated useful lives of five years. Amortization expense is expected to be $48,000 for the year ending December 31, 2007 and $32,000 for the year ending December 31, 2008.

Long-Lived Assets

The Company reviews long-lived assets, including property and equipment, and intangible assets for impairment whenever events or changes in business circumstances indicate that the carrying amounts of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. Impairment, if any, is assessed using discounted cash flows. Through December 31, 2006, there have been no such impairment losses.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date.

Stock-Based Compensation

Beginning January 1, 2006, the Company accounted for its employee stock option plans under the provisions of SFAS No. 123R. SFAS No. 123R requires the recognition of the fair value of stock-based compensation in net income. The fair value of the Company’s stock options was estimated using a Black-Scholes option valuation model. This model requires the input of highly subjective assumptions and elections in adopting and implementing SFAS No. 123R, including expected stock price volatility and the estimated life of each award. The fair value of stock-based awards is amortized over the vesting period of the award. The Company has elected to use the straight-line amortization method for awards granted after the adoption of SFAS No. 123R and continues to use a graded vesting amortization method for awards granted prior to the adoption of SFAS No. 123R.

The Company’s financial statements for the year ended December 31, 2006 reflect the impact of SFAS 123R using the modified prospective transition method. In accordance with the modified prospective

NOTES TO FINANCIAL STATEMENTS—(Continued)

transition method, the Company’s financial statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123R. Share-based compensation expense is based on the value of the portion of share-based payment awards that is ultimately expected to vest. Share-based compensation expense recognized in the Company’s Financial Statements for the year ended December 31, 2006 included compensation expense for share-based payment awards granted prior to, but not yet vested as of, December 31, 2005 based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS No. 123, Accounting for Stock-Based Compensation (“SFAS 123”), and compensation expense for the share-based payment awards granted subsequent to December 31, 2005 based on the grant date fair value estimated in accordance with the provisions of SFAS 123R.

Upon adoption of SFAS No. 123R, the Company has elected the “long form” method for calculating the tax effects of stock-based compensation pursuant to SFAS No. 123R, paragraph 81. Under the “long form” method, the Company determines the beginning balance of the additional paid-in capital pool (“APIC pool”) related to the tax effects of the employee stock-based compensation “as if” the Company had adopted the recognition provisions of SFAS No. 123 since its effective date of January 1, 1995. The Company also determines the subsequent impact on the APIC pool and Consolidated Statement of Cash Flows of the tax effect of employee stock—based compensation awards that were issued after the adoption of SFAS No. 123R and outstanding at the adoption date.

Consistent with prior years, the Company uses the “with and without” approach as described in EITF Topic No. D-32 in determining the order in which our tax attributes are utilized. The “with and without” approach results in the recognition of the windfall stock option tax benefits only after all other tax attributes of the Company’s have been considered in the annual tax accrual computation. SFAS 123R prohibits the recognition of a deferred tax asset for an excess tax benefit that has not yet been realized. As a result, the Company will only recognize a benefit from stock-based compensation in paid-in-capital if an incremental tax benefit is realized after all other tax attributes currently available to the Company have been utilized. In addition, the Company has elected to account for the indirect benefits of stock-based compensation on items such as the research tax credit or the domestic manufacturing deduction through the consolidated statement of income (continuing operations) rather than through paid-in-capital.

See Note 6 of our Financial Statements for further information regarding stock-based compensation.

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts related to the estimated losses that may result from the inability of its customers to make required payments. This allowance is determined based upon historical experience and any specific customer collection issues that have been identified. Historically, the Company has not experienced significant credit losses related to an individual customer or groups of customers in any particular industry or geographic area.

The Company’s allowance for doubtful accounts is included in accounts receivable as follows (in thousands):

Inventories and Cost of Product Sales

Inventories are stated at the lower of standard cost determined on a FIFO basis or market value. Cost of product sales represents the cost of materials, direct labor and overhead associated with the manufacture of our products, delivery charges, lab services and royalties.

Advertising Expense

The cost of advertising is expensed as incurred. Advertising expense for the years ended December 31, 2006, 2005, and 2004 was approximately $2,436,000, $1,369,000, and $1,057,000, respectively. The cost of advertising was included in selling and marketing expenses in the statements of income. The balance of capitalized advertising expense on the balance sheet was approximately $0.1 million as of December 31, 2006. There was no capitalized advertising expense on the balance sheet as of December 31, 2005.

Shipping and Handling Costs

The Company records shipping and handling costs billed to its customers as product sales and the related expense as cost of products sold.

Net Income Per Share

Basic net income per share is calculated by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed by dividing net income by the weighted-average number of common shares and dilutive potential common shares outstanding for the period. For purposes of this calculation, options, and warrants are considered to be potential common shares and are only included in the calculation of diluted net income per share when their effect is dilutive.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“FAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and is effective for the Company as of January 1, 2008. The Company does not believe that the adoption of SFAS 157 will materially impact its results of operations, financial position or cash flows.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109” (FIN 48). FIN 48 applies to all tax positions related to income taxes subject to FASB Statement 109, Accounting for Income Taxes. Under FIN 48, a company would recognize the benefit from a tax position only if it is more-likely-than-not that the position would be sustained upon audit based solely on the technical merits of the tax position. FIN 48 clarifies how a company would measure the income tax benefits from the tax positions that are recognized, provides guidance as to the timing of the derecognition of previously recognized tax benefits and describes the methods for classifying and disclosing the liabilities within the financial statements for any unrecognized tax benefits. FIN 48 also addresses when a company should record interest and penalties related to tax positions and how the interest and penalties may be classified within the income statement and presented in the balance sheet. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company expects to adopt FIN 48 at the beginning of its fiscal year

2007. Differences between the amounts recognized in the statements of operations prior to and after the adoption of FIN 48 would be accounted for as a cumulative effect adjustment to the beginning balance of retained earnings. The Company does not expect the adoption of FIN 48 to have a material impact on its financial position, results of operations or cash flows.

2. LICENSE ARRANGEMENTS

Adeza has entered into license, clinical trial, supply, and sponsored research and development agreements with universities, research organizations, and commercial companies. Certain of these agreements require payments of royalties on future sales of products resulting from such agreements and may subject Adeza to minimum annual royalty payments to such contract partners. During the years ended December 31, 2006, 2005, and 2004, the total of such royalty costs recorded were approximately $3,116,000, $2,695,000 and $1,900,000, respectively, excluding the effect of a non-recurring reduction in accrued royalties and related royalty costs of $2.7 million that was recorded in the year ended December 31, 2004. Royalty costs are included in cost of product sales. The non-recurring reduction of $2.7 million was primarily related to significant new information that Adeza received in October 2004 which allowed Adeza to conclude that no royalties were due or are required under a license agreement.

Leases

The Company leases facilities and office equipment under non-cancelable operating leases. The future minimum lease obligations are as follows (in thousands):

|  | Payments Due in
Contractual Obligations |  | Total |  | 2007 |  | 2008 |  | 2009 |  | 2010 and thereafter

The facility lease obligations are comprised of a facility lease with one-year terms expiring on September 30, 2007. The Company also maintains several office equipment leases which expire on December 31, 2011.

Rent expense was approximately $224,000, $204,000 and $203,000 for the years ended December 31, 2006, 2005, and 2004, respectively.

6. STOCK-BASED COMPENSATION

Effective January 1, 2006, the Company adopted the provisions of SFAS No. 123R. SFAS No. 123R establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured on the grant date, based on the fair value of the award and is recognized as an expense over the employee requisite service period. Prior to January 1, 2006, the Company accounted for its stock-based awards under the recognition and measurement provisions of Accounting Principles Board Opinion No. 25 “Accounting for Stock Issued to Employees” and related Interpretations as permitted by SFAS No. 123.

Prior to the Adoption of SFAS No. 123R

Prior to the adoption of SFAS No. 123R, the Company provided disclosures required under SFAS No. 123, “Accounting for Stock-Based Compensation,” (“SFAS No. 123”) as amended by SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosures.” $1.0 million of employee stock-based compensation expense was reflected in net income for the year ended December 31, 2005, respectively.

NOTES TO FINANCIAL STATEMENTS—(Continued)

During the preparation of the notes to the consolidated condensed financial statements for the three months ended March 31, 2006, the Company determined that the calculation of its pro forma net income reported under SFAS 123 for the year ended December 31, 2005, as previously reported, was understated primarily as a result of an incorrect change in the fair value calculation (and, therefore, the amortization expense related to) options granted in August 2004. Accordingly, pro forma net income reported under SFAS 123 for the year ended December 31, 2005, presented in the tables below, was revised. These revisions had no effect on the Company’s previously reported results of operations or financial condition. The stock-based employee and director compensation expense previously reported for the year ended December 31, 2005 was $2.6 million, and the pro forma net income previously reported for the year ended December 31, 2005 was $10.8 million.

Impact of Adoption of SFAS No. 123R

The Company elected to adopt the modified prospective application method as provided by SFAS No. 123R. Under that transition method, compensation costs recognized in the year ended December 31, 2006, include (a) compensation cost for all share-based payments granted prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123, and (b) compensation costs for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123R.

In the year ended December 31, 2006, we recognized compensation expense in connection with the adoption of FAS 123R of $3.3 million. Diluted earnings per share was reduced by $0.07 for the year ended December 31, 2006, respectively, as a result of the Company’s adoption of FAS 123R. As of December 31, 2006 the stock-based compensation capitalized as inventory was minimal.

As a result of adoption FAS 123R, the Company’s income before income taxes and net income for the year ended December 31, 2006 are $2.4 million and $1.0 million lower, respectively, than if the Company had continued to account for share-based compensation under Opinion 25.

Equity Incentive Program

The Company’s equity incentive program is a long-term retention program that is intended to attract and retain qualified management and technical employees and align stockholder and employee interests. At December 31, 2006, the equity incentive program consisted of the 2004 Equity Incentive Plan (the 2004 Plan). Under the 2004 Plan, options, stock appreciation rights, stock purchase rights and restricted stock may be issued to employees, officers, directors, and consultants of Adeza. The 2004 Plan permits the grant of share options for up to 1,875,000 shares of common stock. The maximum number of shares shall be increased annually on January 1 of each year by a number of shares equal to the lesser of (a) three percent of the number of shares issued and outstanding on the immediately preceding December 31, (b) 525,000 Shares, and (c) a number of Shares set by the Board. The 2004 Plan provides that the exercise price for incentive stock options will be no less than 100% of fair value of Adeza’s common stock on the date of grant. Generally, these options vest ratably over four years and have a term of 10 years. No restricted stock, stock appreciation or purchase rights have been issued as of September 30, 2006.

The following table provides certain information with respect to the 2004 Plan, which was in effect as of December 31, 2006:

|  | Number of Securities to be Issued upon Exercise of Outstanding Options (a) |  | Weighted-Average Exercise Price of Outstanding Options (b) |  | Number of Securities Remaining Available for Future Issuance Under Equity Compensation Plan (Excluding Securities Reflected in Column (a)) (c)
Equity compensation plan approved by security holders |  | 1,112,702 |  | $ | 15.71 |  | 1,834,517

Upon adoption of SFAS 123(R), the Company used a blended historical volatility in deriving the expected volatility assumption as allowed under SFAS 123(R) and Staff Accounting Bulletin No. 107, or SAB 107. The blended historical volatility was based on a blend of the Company’s own historical experience and the Company’s peer group historical experience. The risk-free interest rate assumption was based upon observed interest rates appropriate for the term of our stock options. The expected term of stock options was based on a blend of the Company’s own historical experience and the Company’s peer group historical experience. As stock-based compensation expense recognized in the Statements of Income for the year ended December 31, 2006 was based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on the Company’s historical experience.

The fair value of stock options granted to employees in the years ended December 31, 2006, 2005 and 2004 was estimated at the date of grant using the Black-Scholes model using the following weighted-average assumptions:

|  | Year Ended December 31, |
|  | 2006 |  |  | 2005 |  |  | 2004 |
Expected volatility |  | 60 | % |  | 72 | % |  | 85 | %
Risk-free interest rate |  | 4.83 | % |  | 4.1 | % |  | 3.3 | %
Expected term (in years) |  | 4.9 |  |  | 4.6 |  |  | 4.0 |
Dividends |  | — |  |  | — |  |  | — |

SFAS No. 123R requires the use of option pricing models that were not developed for use in valuing employee stock options. The Black-Scholes option-pricing model was developed for use in estimating the fair value of short-lived exchange traded options that have no vesting restrictions and are fully transferable. In addition, option-pricing models require the input of highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock.

Stock option plans

2004 Equity Incentive Plan

In August 2004, the Company’s board of directors and stockholders approved the 2004 Equity Incentive Plan (the 2004 Plan), which became effective upon the completion of the Company’s initial public offering in December 2004. The Company has reserved a total of 1,875,000 shares of its common stock for issuance under the 2004 Plan, all of which are available for future grant. Under the 2004 Plan options, stock appreciation, stock purchase rights and restricted stock can be issued to employees, officers, directors, and consultants of Adeza. The 2004 Plan provides that the exercise price for incentive stock options will be no less than 100% of the fair value of Adeza’s common stock on the date of grant. Generally, these options vest ratably over four years and have a term of 10 years. There were no shares subject to repurchase as of December 31, 2006. No restricted stock, stock appreciation or purchase rights had been issued as of December 31, 2006.

1995 Stock Option and Restricted Stock Plan

In August 2004, the Company’s Board of Directors and stockholders approved amendments to the Company’s 1995 Stock Option and Restricted Stock Plan (the 1995 Plan) so that, upon completion of the Company’s initial public offering, the shares that were available for future grant under the 1995 Plan were allocated to the 2004 Plan. Additionally, any shares that are issuable upon exercise of options outstanding under the 1995 Plan that are forfeited after the completion of the Company’s initial public offering, are allocated to the 2004 Plan.

Under the 1995 Plan options and purchase rights were issuable to employees, officers, directors, consultants, and promotional representatives of Adeza. The 1995 Plan provided that the exercise price for incentive stock options would be no less than 100% of the fair value of Adeza’s common stock (no less than 85% of the fair value for nonqualified stock options), as determined by the Board of Directors on the date of grant. Generally, these options are immediately exercisable, subject to repurchase rights which lapse ratably over four years and have a term of 10 years. There were no shares subject to repurchase as of December 31, 2006 and 2005. No restricted stock purchase rights had been issued as of December 31, 2006.

Stock options that expired during the year ended December 31, 2006 were minimal.

The weighted average grant date fair value of options granted during the year ended December 31, 2006 was $7.26 per share. The total intrinsic value of options exercised during the year ended December 31, 2006 was approximately $2.4 million.

Warrants

In conjunction with a loan and security agreement with MMC/GATX Partnership No. 1 and Transamerica Business Credit Corporation, Adeza issued warrants to purchase 236,301 shares of Series 3 convertible preferred stock at an exercise price of $2.92 per share. The warrants are scheduled to expire on the later of ten years from the date of the grant or five years after the closing of a public offering. The fair value assigned to these warrants, as determined using the Black-Scholes valuation model, was approximately $475,000. In determining the fair value of the warrants the following assumptions were used: expected volatility of 50%; expected life of 10 years; expected dividend yield of 0%; risk-free interest rate of 6%; stock price at date of grant and exercise price of $2.92 per share. The fair value of these warrants was netted against the related debt and was amortized to interest expense over the terms of the various notes. The Company amortized $24,000 as interest expense in the year ended December 31, 2003 related to these warrants. No interest was amortized in the years ended December 31, 2005 and 2006 related to these warrants. As a result of the completion of the Company’s initial public offering

The Company’s income tax provision (benefit) differs from the amounts computed by applying the federal statutory income tax rate of 34% to pretax income (loss) for the years ended December 31, 2004 and 2005 and 35% to pretax income (loss) for the year ended December 31, 2006 as follows:

|  | Years Ended December 31, |
|  | 2006 |  | 2005 |  |  | 2004 |
|  | (In thousands) |
U.S. federal taxes at federal statutory rate |  | $ | 2,110 |  | $ | 2,657 |  |  | $ | 3,155 |
State taxes, net of federal benefit |  |  | 403 |  |  | (135 | ) |  |  | 132 |
Net operating losses not benefitted (benefitted) |  |  | — |  |  | (7,407 | ) |  |  | (3,091 | )
Non deductible stock compensation |  |  | 784 |  |  | 215 |  |  |  | — |
Other individually immaterial items |  |  | 205 |  |  | 158 |  |  |  | 214 |
Total provision (benefit) |  | $ | 3,502 |  | $ | (4,512 | ) |  | $ | 410 |

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s net deferred tax assets are as follows:

|  | December 31, |
|  | 2006 |  | 2005 |
|  | (In thousands) |
Deferred tax assets: |  |  |  |  |  |  |
Net operating losses |  | $ | 1,976 |  | $ | 5,054 |
Research credits |  |  | 1,646 |  |  | 1,531 |
Capitalized research and development |  |  | 171 |  |  | 156 |
Other, net |  |  | 652 |  |  | 691 |
Non-deductible stock compensation |  |  | 683 |  |  | — |
Total deferred tax assets |  |  | 5,128 |  |  | 7,432 |
Valuation allowance |  |  | — |  |  | (2,310 | )
Net deferred tax assets |  | $ | 5,128 |  | $ | 5,122 |

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. In December 2006, based upon the level of historical taxable income and projections for future taxable income, we concluded that it was more likely than not that our deferred tax assets would be realized with the exception of deferred tax assets related to stock option benefits. The valuation allowance decreased by $2,310,000 and $6,960,000, and increased by $8,070,000 during the years ended December 31, 2006, 2005 and 2004, respectively.

The Company is tracking the portion of its deferred tax assets attributable to stock option benefits in a separate memo account pursuant to SFAS No. 123R. Therefore, these amounts are no longer included in the Company’s gross or net deferred tax assets. Pursuant to SFAS No. 123R, footnote, 82, the benefit of these stock option benefits will only be recorded to equity when they reduce cash taxes payable. As a result, $1,715,000 of the change in the valuation allowance in 2006 related to amounts accounted for in the memo account.

The Company’s income taxes payable for federal and state tax purposes has been reduced by the tax benefits associated with the exercise of stock option in the current year. The benefits applicable to stock options were credited to equity during the years ended December 31, 2006 and 2005 were $3,247,000 and $260,000, respectively.

As of December 31, 2006, the Company had federal net operating loss carry forwards of approximately $9,970,000. The Company also has state net operating loss carryforwards of approximately $3,690,000. The Company also had federal and state research and development tax credit carry forwards of approximately $600,000 and $1,100,000, respectively. The federal net operating loss and tax credit carry forwards will expire at various dates beginning in 2007 through 2024, if not utilized. The state net operating losses expires at various dates beginning in 2007. The state research and development tax credit carry forward indefinitely. The Company also has alternative minimum tax credit carryforwards of $270,000 which have no expiration date.

As of December 31, 2006, the portion of the federal net operating loss carry forward which relate to stock option benefits is approximately $4,200,000. The portion of the state net operating loss carry forward which relate to stock option benefits is approximately $3,690,000. Pursuant to SFAS No 123R, the benefit of these net operating loss carry forwards will only be recorded to equity when they reduce cash taxes payable.

The Company has reviewed whether the utilization of its net operating losses and research credits were subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. We do not expect the disclosed net operating losses and research credits carryovers to expire before utilization.

9. BENEFIT PLAN

The Company’s 401(k) Plan allows eligible employees to make contributions of their qualified compensation subject to IRS limits. The Company has the discretion to make matching contributions each year. The Company had not made any matching contributions through January 31, 2007. Effective February 1, 2007, the Company began matching 50% up to a maximum of $3,000 per employee. Employees become eligible for participation in the 401(k) Plan after completing 30 days of employment with the Company.

10. RELATED PARTY TRANSACTIONS

In 2000, a loan offer was made to an officer of the Company. The agreement to the loan was ratified by the Board of Directors on April 21, 2001, for an amount of $183,000, with the minimum interest rate allowed by the internal revenue service. According to the terms agreed upon, 20% of the loan would be forgiven in principal and accrued interest at the end of each twelve months of employment. The loan would be due and payable within 30 days following termination by Adeza for cause. In the event of a change of control or merger with another company or of termination without cause, the loan and accumulated interest would be forgiven. The loan contemplated was executed on February 28, 2003 for $109,800, which was issued to the officer at that time. All other terms were in accordance with the original loan offer. Subject to the officer’s continued employment, the loan and related interest would have been forgiven in 2003 to 2006. On August 4, 2004, the Company, upon approval of its Board of Directors, forgave the remaining balance of the loan. In the year ended December 31, 2004, $76,250 of the principal was forgiven and recorded to general and administrative expenses.

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to Hologic, Inc. (the “Company”) of the Consideration (as defined below) in the aggregate to be paid by the Company in respect of each share of the common stock, par value $0.01 per share (the “Cytyc Common Stock”), of Cytyc Corporation (“Cytyc”) pursuant to the Agreement and Plan of Merger, dated as of May 20, 2007 (the “Agreement”), among the Company, Nor’easter Corp., a wholly owned subsidiary of the Company (“Merger Sub”), and Cytyc. Pursuant to the Agreement, Cytyc will be merged with and into Merger Sub (the “Merger”) and each outstanding share of Cytyc Common Stock will be converted into $16.50 in cash (the “Cash Consideration”) and 0.520 of a share of common stock, par value $0.01 per share (the “Company Common Stock”), of the Company (the “Stock Consideration”). The Stock Consideration, together with the Cash Consideration, is hereinafter referred to as the “Consideration”.

Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the “Transaction”). We expect to receive fees for our services in connection with the Transaction, all of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. We provided certain investment banking services to the Company and Cytyc from time to time, for which we have received, and may receive, compensation. We also may provide investment banking services to the Company in the future for which we may receive compensation.

Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, Cytyc and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and Cytyc for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.

In connection with this opinion, we have reviewed, among other things, the Agreement, annual reports to stockholders and Annual Reports on Form 10-K of the Company and Cytyc for the five fiscal years ended on the Saturday closest to September 30, 2006 for the Company, and December 31, 2006 for Cytyc; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and Cytyc; certain other communications from the Company and Cytyc to their respective stockholders; certain internal financial analyses and forecasts for Cytyc prepared by its management, as reviewed by the management of the Company, certain internal financial analyses and forecasts for the Company prepared by its management and certain internal pro forma analyses and forecasts for the Company and Cytyc prepared by the management of the Company (the “Forecasts”), including certain cost savings and operating synergies projected by the managements of the

Company and Cytyc to result from the Transaction (the “Synergies”). We also have held discussions with members of the senior managements of the Company and Cytyc regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of the Company and Cytyc. In addition, we have reviewed the reported price and trading activity for the shares of Company Common Stock and the shares of Cytyc Common Stock, compared certain financial and stock market information for Cytyc and the Company with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the medical device and diagnostics industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.

For purpose of rendering this opinion, we have relied upon and assumed, without assuming any responsibility for independent verifications, the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the Forecasts, including Synergies, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company and Cytyc. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or Cytyc or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We also have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or Cytyc or on the expected benefits of the Transaction in any way meaningful to our analysis.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, nor are we expressing any opinion as to the prices at which shares of Company Common Stock will trade at any time. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction, and such opinion does not constitute a recommendation as to how any holder of Company Common Stock should vote with respect to such Transaction.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration in the aggregate to be paid by the Company in respect of each share of Cytyc Common Stock pursuant to the Agreement is fair from a financial point of view to the Company.

Very truly yours,
/s/ Goldman, Sachs & Co.

Members of the Board of Directors:

We understand that Hologic, Inc. (the “Company”), Nor’easter Corp., a wholly-owned subsidiary of the Company (“Merger Sub”), and Cytyc Corporation (“Cytyc”) propose to enter into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Cytyc will merge with and into the Merger Sub (the “Merger”) in a transaction in which each outstanding share of common stock, par value $0.01 per share, of Cytyc, other than shares of Cytyc common stock held in the treasury of Cytyc or owned by the Company or a subsidiary of the Company, all of which shares will be canceled, or as to which dissenters rights have been properly exercised, will be converted into the right to receive (a) $16.50 in cash, without interest (the “Cash Merger Consideration”), and (b) 0.52 shares of the common stock, par value $0.01 per share, of the Company (the “Stock Merger Consideration,” and together with the Cash Merger Consideration and cash in lieu of fractional shares of Company common stock as described in the Merger Agreement, the “Merger Consideration”). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Merger Consideration to be paid by the Company pursuant to the Merger Agreement is fair, from a financial point of view, to the Company.

In arriving at our opinion, we have, among other things:

| (i) | reviewed a draft of the Merger Agreement, dated May 19, 2007;

| (ii) | reviewed certain publicly available financial and other information about the Company and Cytyc;

| (iii) | reviewed certain information furnished to us by the Company’s management, including financial forecasts and analyses, relating to the business, operations and prospects of the Company;

| (iv) | reviewed certain information furnished to us by Cytyc’s management, including financial forecasts and analyses, relating to the business, operations and prospects of Cytyc;

| (v) | held discussions with members of senior management of the Company concerning the matters described in clauses (ii), (iii) and (iv) above;

| (vi) | held discussions with members of senior management of Cytyc concerning the matters described in clause (ii) and (iv) above;

| (vii) | reviewed certain publicly available information, including share trading price history and valuation multiples, of certain publicly traded companies that we deemed comparable to Cytyc;

| (viii) | compared the proposed financial terms of the Merger with the financial terms of certain other transactions that we deemed relevant; and

| (ix) | conducted such other financial studies, analyses and investigations as we deemed appropriate.

In our review and analysis and in rendering this opinion, we have assumed and relied upon, but have not assumed any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by the Company or Cytyc or that was publicly available to us (including, without limitation, the information described above), or that was otherwise reviewed by us. In our review, we did not obtain any independent evaluation or appraisal of any of the assets or liabilities of, nor did we conduct a physical inspection of any of the properties or facilities of, the Company or Cytyc, nor have we been furnished with any such evaluations or appraisals of such physical inspections, nor do we assume any responsibility to obtain any such evaluations or appraisals.

With respect to the financial forecasts provided to and examined by us, we note that projecting future results of any company is inherently subject to uncertainty. The Company and Cytyc have informed us, however, and we have assumed, that such financial forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Company and Cytyc as to the future financial performance of the Company and Cytyc, respectively. We express no opinion as to such financial forecasts or the assumptions on which they are made.

Our opinion is based on economic, monetary, regulatory, market and other conditions existing and which can be evaluated as of the date hereof. We expressly disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting our opinion of which we become aware after the date hereof.

We have made no independent investigation of any legal or accounting matters affecting the Company or Cytyc, and we have assumed the correctness in all respects material to our analysis of all legal and accounting advice given to the Company and its Board of Directors, including, without limitation, advice as to the legal, accounting and tax consequences of the terms of, and transactions contemplated by, the Merger Agreement to the Company and its stockholders. In addition, in preparing this opinion, we have not taken into account any tax consequences of the transaction to the Company. We have assumed that the final form of the Merger Agreement will be substantially similar to the last draft reviewed by us. We have also assumed that in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on the Company, Cytyc or the contemplated benefits of the Merger.

It is understood that our opinion is for the use and benefit of the Board of Directors of the Company in its consideration of the Merger, and our opinion does not address the relative merits of the transactions contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to the Company, nor does it address the underlying business decision by the Company to engage in the Merger or the terms of the Merger Agreement or the documents referred to therein. Our opinion does not constitute a recommendation as to how any holder of shares of Company common stock should vote on the Merger or any matter related thereto. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of the Company.

We express no opinion as to the price at which shares of Company common stock will trade at any time.

Marlborough, MA 01752

Members of the Board

We understand that Cytyc Corporation (“Cytyc” or the “Company”), Hologic, Inc. (“Hologic”) and Nor’easter Corp., a wholly owned subsidiary of Hologic (“Merger Sub”) propose to enter into an Agreement and Plan of Merger, in the form dated May 20, 2007 (the “Merger Agreement”), which provides, among other things, for the merger (the “Merger”) of Cytyc with and into Merger Sub at which time the separate existence of Cytyc shall cease and Merger Sub shall be a wholly owned subsidiary of Hologic. Each outstanding share of common stock, par value $0.01 per share of Cytyc (the “Cytyc Common Stock”), other than shares held in treasury or held by Hologic, any Subsidiary (as defined in the Merger Agreement) of Hologic or Merger Sub, or dissenting shares as defined in the Merger Agreement will be converted into the right to receive (i) 0.52 shares of Hologic Stock (as defined in the Merger Agreement) plus (ii) $16.50 in cash. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the consideration to be received by the holders of shares of Cytyc Common Stock pursuant to the Merger Agreement is fair from a financial point of view to such holders.

For purposes of the opinion set forth herein, we have:

| i) | reviewed certain publicly available financial statements and other business and financial information of the Company and Hologic;

| ii) | reviewed certain internal financial statements and other financial and operating data concerning the Company and Hologic, respectively;

| iii) | reviewed certain financial projections prepared by the managements of the Company and Hologic, respectively;

| iv) | discussed the past and current operations and financial condition and the prospects of the Company and Hologic, including information relating to certain strategic, financial and operational benefits anticipated from the Merger, with senior executives of the Company and Hologic, respectively;

| v) | reviewed the reported prices and trading activity for the Cytyc Common Stock and the Hologic Common Stock;

| vi) | reviewed the pro forma impact of the Merger on Hologic’s earnings per share, cash flow, consolidated capitalization and financial ratios;

| vii) | compared the financial performance of the Company and Hologic and the prices and trading activity of the Cytyc Common Stock and Hologic Common Stock with that of certain other comparable publicly-traded companies and their securities, respectively;

| viii) | reviewed the financial terms, to the extent publicly available, of certain comparable acquisition transactions;

| ix) | participated in discussions and negotiations among representatives of the Company and Hologic and certain other parties and their financial and legal advisors;

| x) | reviewed the Merger Agreement and certain related documents; and,

| xi) | performed such other analyses and considered such other factors as we have deemed appropriate.

We have assumed and relied upon without independent verification the accuracy and completeness of the information reviewed by us for the purposes of this opinion. With respect to the financial projections, including information relating to certain strategic, financial and operational benefits anticipated from the Merger, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of the Company and Hologic. In addition, we have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the Merger will be treated as a tax-free reorganization and/or exchange, each pursuant to the Internal Revenue Code of 1986, as amended. We have relied upon, without independent verification, the assessment by the managements of the Company and Hologic of: (i) the strategic, financial and other benefits expected to result from the Merger; (ii) the timing and risks associated with the integration of the Company and Hologic; (iii) their ability to retain key employees of the Company and Hologic, respectively and (iv) the validity of, and risks associated with, the Company and Hologic’s existing and future technologies, intellectual property, products, services and business models. We are not legal, tax or regulatory advisors. We are financial advisors only and have relied upon, without independent verification, the assessment of Hologic and the Company and their legal, tax or regulatory advisors with respect to such matters. We have not made any independent valuation or appraisal of the assets or liabilities of the Company, nor have we been furnished with any such appraisals. Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

In arriving at our opinion, we were not authorized to solicit, and did not solicit, interest from any party with respect to the acquisition, business combination or other extraordinary transaction, involving the Company or any of its assets, nor did we negotiate with any party other than Hologic.

We have acted as financial advisor to the Board of Directors of the Company in connection with this transaction and will receive a fee for our services, which is contingent upon the closing of the Merger. In the past, Morgan Stanley & Co. Incorporated and its affiliates have provided financial advisory and financing services for the Company and have received fees for the rendering of these services. Morgan Stanley may also seek to provide such services to Hologic and the Company in the future and will receive fees for the rendering of these services. In the ordinary course of our trading, brokerage, investment management and financing activities, Morgan Stanley or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for our own account or the accounts of customers, in debt or equity securities or senior loans of Hologic, the Company or any other company or any currency or commodity that may be involved in this transaction.

It is understood that this letter is for the information of the Board of Directors of the Company and may not be used for any other purpose without our prior written consent, except that a copy of this opinion may be included in its entirety in any filing the Company is required to make with the Securities and Exchange Commission in connection with this transaction if such inclusion is required by applicable law. In addition, this opinion does not in any manner address the prices at which the Hologic Stock will trade following consummation of the Merger and Morgan Stanley expresses no opinion or recommendation as to how the shareholders of the Company and Hologic should vote at the shareholders’ meetings to be held in connection with the Merger.

Based on and subject to the foregoing, we are of the opinion on the date hereof that the consideration to be received by the holders of shares of the Cytyc Common Stock pursuant to the Merger Agreement is fair from a financial point of view to such holders.

The Board of Directors

Cytyc Corporation

250 Campus Drive

Marlborough, MA 01752

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of common stock, par value $0.01 per share (the “Company Common Stock”), of Cytyc Corporation (the “Company”) of the consideration to be received by such holders in the proposed merger (the “Merger”) of the Company with a wholly-owned subsidiary of Hologic, Inc. (the “Merger Partner”). Pursuant to the Agreement and Plan of Merger, dated as of May 20, 2007 (the “Agreement”), among the Company, the Merger Partner and Nor’easter Corp. (“Merger Subsidiary”), the Company will become a wholly-owned subsidiary of the Merger Partner, and each outstanding share of Company Common Stock, other than shares of Company Common Stock held in treasury or owned by the Merger Partner and its subsidiaries, will be converted into the right to receive consideration equal to 0.52 shares (the “Stock Consideration”) of the Merger Partner’s common stock, par value $0.01 per share (the “Merger Partner Common Stock”) and $16.50 per share in cash, without interest, (the “Cash Consideration”, and, together with the Stock Consideration, the “Consideration”).

In arriving at our opinion, we have (i) reviewed the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the Merger Partner and the industries in which they operate; (iii) compared the proposed financial terms of the Merger with the publicly available financial terms of certain transactions involving companies we deemed relevant and the consideration received for such companies; (iv) compared the financial and operating performance of the Company and the Merger Partner with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical’ market prices of the Company Common Stock and the Merger Partner Common Stock and certain publicly traded securities of such other companies; (v) reviewed certain internal financial analyses and forecasts prepared by the management of the Merger Partner relating to the business of the Merger Partner; (vi) reviewed certain internal financial analyses and forecasts prepared by the management of the Company relating to the businesses of the Company and the Merger Partner, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the Merger (the “Synergies”); and (vii) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Company and the Merger Partner with respect to certain aspects of the Merger, and the past and current business operations of the Company and the Merger Partner, the financial condition and future prospects and operations of the Company and the Merger Partner, the effects of the Merger on the financial condition and future prospects of the Company and the Merger Partner, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed, without assuming responsibility or liability for independent verification, he accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company and the Merger Partner or otherwise reviewed by or for us. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Company or the Merger Partner under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us, including the Synergies, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management of the Company as to the expected future

results of operations and financial condition of the Company and the Merger Partner to which such analyses or forecasts relate. We express no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. We have also assumed that the Merger will qualify as a tax-free reorganization for United States federal income tax purposes, and that the other transactions contemplated by the Agreement will be consummated as described in the Agreement. We have also assumed that the representations and warranties made by the Company and the Merger Partner in the Agreement and the related agreements are and will be true and correct in all ways material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Merger will be obtained without any adverse effect on the Company or the Merger Partner or on the contemplated benefits of the Merger.

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, of the Consideration to be received by the holders of the Company Common Stock in the proposed Merger and we express no opinion as to the fairness of the Merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Merger. We are expressing no opinion herein as to the price at which the Company Common Stock or the Merger Partner Common Stock will trade at any future time.

In addition, we were not requested to and did not provide advice concerning the structure, the specific amount of the Consideration, or any other aspects of the Merger, or to provide services other than the delivery of this opinion. We were not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of the Company or any other alternative transaction. We also note that we did not participate in negotiations with respect to the terms of the Merger and related transactions.

We will receive a fee from the Company for the delivery of this opinion. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. We and our affiliates have performed in the past, and may continue to perform, certain services for the Company, the Merger Partner and their respective affiliates, all for customary compensation, including our representation of the Company in its 2007 acquisition of Adeza Biomedical Corporation and our representation of Merger Partner in connection with its 2006 acquisition of R2 Technology, Inc. In the ordinary course of our businesses, we and our affiliates may actively trade the debt and equity securities of the Company or the Merger Partner for our own account or for the accounts of customers and, accordingly, we may at any time hold long or short positions in such securities.

On the basis of and subject to the foregoing, it is our opinion as of the date hereof that the Consideration to be received by the holders of the Company Common Stock in the proposed Merger is fair, from a financial point of view, to such holders.

This letter is provided to the Board of Directors of the Company in connection with and for the purposes of its evaluation of the Merger. This opinion does not constitute a recommendation to any shareholder of the Company as to how such shareholder should vote with respect to the Merger or any other matter. This opinion may not be disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever except with our prior written approval. This opinion may be reproduced in full in any proxy or information statement mailed to shareholders of the Company but may not otherwise be disclosed publicly in any manner without our prior written approval.

CHAPTER 1. DELAWARE GENERAL CORPORATION LAW

Subchapter IX. Merger, Consolidation or Conversion

§ 262. Appraisal rights.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of § 251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

G-1

##### Table of Contents

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

G-2

##### Table of Contents

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation

G-3

##### Table of Contents

of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

Article I.

Stockholders

Section 1.1 Annual Meeting. The annual meeting of the stockholders of the corporation shall be held on such date as shall be fixed by the board of directors, at such time and place within or without the State of Delaware as may be designated in the notice of meeting. The Board may, in its sole discretion, determine that the annual meeting of stockholders shall not be held at any place, but may instead be held solely by means of remote communication as authorized by the General Corporation Law of the State of Delaware (the “DGCL”). If the day fixed for the annual meeting shall fall on a legal holiday, the meeting shall be held on the next succeeding day not a legal holiday. If the annual meeting is omitted on the day herein provided, a special meeting may be held in place thereof, and any business transacted at such special meeting in lieu of annual meeting shall have the same effect as if transacted or held at the annual meeting.

Section 1.2 Special Meetings. Special meetings of the stockholders may be called at any time only by the president, chief executive officer or the board of directors. Special meetings of the stockholders shall be held at such time, date and place within or outside of the State of Delaware as may be designated in the notice of such meeting. The Board may, in its sole discretion, determine that a special meeting of stockholders shall not be held at any place, but may instead be held solely by means of remote communication as authorized by the DGCL.

Section 1.3 Notice of Meeting. A written notice stating the place, if any, date, and hour of each meeting of the stockholders, the means of remote communication, if any, by which stockholders and proxy holders may be deemed present in person and vote at such meeting, and, in the case of a special meeting, the purposes for which the meeting is called, shall be given to each stockholder entitled to vote at such meeting, and to each stockholder who, under the Certificate of Incorporation or these by-laws, is entitled to such notice, by delivering such notice to such person or leaving it at their residence or usual place of business, or by mailing it, postage prepaid, and addressed to such stockholder at his address as it appears upon the books of the corporation or by giving notice by electronic transmission as permitted by Section 8.10 of these by-laws, at least ten (10) days and not more than sixty (60) before the meeting. Such notice shall be given by the secretary, an assistant secretary, or any other officer or person designated either by the secretary or by the person or persons calling the meeting.

The requirement of notice to any stockholder may be waived (i) by a written waiver of notice, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether executed or transmitted before or after the meeting by the stockholder or his attorney thereunto duly authorized, and filed with the records of the meeting, (ii) if communication with such stockholder is unlawful, (iii) by attendance at the meeting without protesting prior thereto or at its commencement the lack of notice, or (iv) as otherwise excepted by law. A waiver of notice or electronic transmission of any regular or special meeting of the stockholders need not specify the business to be transacted or the purposes of the meeting unless so required by the Certificate of Incorporation or these by-laws.

If a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place, if any, thereof, and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken, except that if the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. At the adjourned meeting, the corporation may transact any business which might have been transacted at the original meeting.

Section 1.4 Notice of Stockholder Business and Nominations.

(A) Annual Meetings of Stockholders.

(1) Nominations of persons for election to the board of directors and the proposal of business to be considered by the stockholders may be made at an annual meeting of stockholders only (a) pursuant to the corporation’s notice of meeting (or any supplement thereto), (b) by or at the direction of the nominating and corporate governance committee of the board of directors or (c) by any stockholder of the corporation who was a stockholder of record of the corporation at the time the notice provided for in this Section 1.4 is delivered to the secretary of the corporation, who is entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 1.4.

(2) For nominations or other business to be properly brought before an annual meeting of stockholders by a stockholder pursuant to clause (c) of paragraph (A)(1) of this Section 1.4, the stockholder must have given timely notice thereof in writing to the secretary of the corporation and any such proposed business other than the nominations of persons for election to the board of directors must constitute a proper matter for stockholder action. To be timely, a stockholder’s notice shall be delivered to the secretary at the principal executive offices of the corporation not later than the close of business on the ninetieth day nor earlier than the close of business on the one hundred twentieth day prior to the first anniversary of the preceding year’s annual meeting (provided, however, that in the event that the date of the annual meeting is more than thirty days before or more than seventy days after such anniversary date, notice by the stockholder must be so delivered not earlier than the close of business on the one hundred twentieth day prior to such annual meeting and not later than the close of business on the later of the ninetieth day prior to such annual meeting or the tenth day following the day on which public announcement of the date of such meeting is first made by the corporation). In no event shall the public announcement of an adjournment or postponement of an annual meeting of stockholders commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. Such stockholder’s notice shall set forth: (a) as to each person whom the stockholder proposes to nominate for election as a director (i) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to and in accordance with Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and (ii) such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the by-laws of the corporation, the language of the proposed amendment), the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the corporation’s books, and of such beneficial owner, (ii) the class and number of shares of capital stock of the corporation which are owned beneficially and of record by such stockholder and such beneficial owner, (iii) a representation that the stockholder is a holder of record of stock of the corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, and (iv) a representation whether the stockholder or the beneficial owner, if any, intends or is part of a group which intends (a) to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the corporation’s outstanding capital stock required to approve or adopt the proposal or elect the nominee and/or (b) otherwise to solicit proxies from stockholders in support of such proposal or nomination. The foregoing notice requirements of this Section 1.4 shall be deemed satisfied by a stockholder if the stockholder has notified the corporation of his or her intention to present a proposal or nomination at an annual meeting in compliance with applicable rules and regulations promulgated under the Exchange Act and such stockholder’s proposal or nomination has

I-2

##### Table of Contents

been included in a proxy statement that has been prepared by the corporation to solicit proxies for such annual meeting. The corporation may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the corporation.

(B) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the corporation’s notice of meeting. Nominations of persons for election to the board of directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the corporation’s notice of meeting (1) by or at the direction of the board of directors or (2) provided that the board of directors has determined that directors shall be elected at such meeting, by any stockholder of the corporation who is a stockholder of record at the time the notice provided for in this Section 1.4 is delivered to the secretary of the corporation, who is entitled to vote at the meeting and upon such election and who complies with the notice procedures set forth in this Section 1.4. In the event the corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the board of directors, any such stockholder entitled to vote in such election of directors may nominate a person or persons (as the case may be) for election to such position(s) as specified in the corporation’s notice of meeting, if the stockholder’s notice required by paragraph (A)(2) of this Section 1.4 shall be delivered to the secretary at the principal executive offices of the corporation not earlier than the close of business on the one hundred twentieth day prior to such special meeting and not later than the close of business on the later of the ninetieth day prior to such special meeting or the tenth day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the board of directors to be elected at such meeting. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above.

(C) General.

(1) Only such persons who are nominated in accordance with the procedures set forth in this Section 1.4 shall be eligible to be elected at an annual or special meeting of stockholders of the corporation to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 1.4. Except as otherwise provided by law, the chairman of the meeting shall have the power and duty (a) to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 1.4 (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination or proposal is made solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by clause (A)(2)(c)(iv) of this Section 1.4) and (b) if any proposed nomination or business was not made or proposed in compliance with this Section 1.4, to declare that such nomination shall be disregarded or that such proposed business shall not be transacted. Notwithstanding the foregoing provisions of this Section 1.4, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the corporation to present a nomination or proposed business, such nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the corporation. For purposes of this Section 1.4, to be considered a qualified representative of the stockholder, a person must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

(2) For purposes of this Section 1.4, “public announcement” shall include disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(3) Notwithstanding the foregoing provisions of this Section 1.4, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 1.4. Nothing in this Section 1.4 shall be deemed to affect any rights (a) of stockholders to request inclusion of proposals or nominations in the corporation’s proxy statement pursuant to applicable rules and regulations promulgated under the Exchange Act or (b) of the holders of any series of Preferred Stock to elect directors pursuant to any applicable provisions of the certificate of incorporation.

Section 1.5 Quorum. The holders of a majority in interest of all stock issued, outstanding and entitled to vote at a meeting shall constitute a quorum. Any meeting may be adjourned from time to time by a majority of the votes properly cast upon the question, whether or not a quorum is present.

Section 1.6 Voting and Proxies. Stockholders shall have one vote for each share of stock entitled to vote owned by them of record according to the books of the corporation, unless otherwise provided by law or by the Certificate of Incorporation. Stockholders may vote either in person or by proxy (whether in writing, by means of electronic transmission or such other means permitted under Delaware law), but no proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. Proxies shall be filed with the secretary of the meeting, or of any adjournment thereof. Except as otherwise limited therein, proxies shall entitle the persons authorized thereby to vote at any adjournment of such meeting. A proxy purporting to be executed by or on behalf of a stockholder shall be deemed valid unless challenged at or prior to its exercise and the burden of proving invalidity shall rest on the challenger. A proxy with respect to stock held in the name of two or more persons shall be valid if executed by one of them unless at or prior to exercise of the proxy the corporation receives a specific written notice to the contrary from any one of them.

Section 1.7 Action at Meeting. When a quorum is present at any meeting, a plurality of the votes properly cast for election to any office shall elect to such office, and a majority of the votes properly cast upon any question other than election to an office shall decide such question, except where a larger vote is required by law, the Certificate of Incorporation or these by-laws. No ballot shall be required for any election unless requested by a stockholder present or represented at the meeting and entitled to vote in the election.

Section 1.8 Action Without Meeting. Any action required or permitted to be taken at any meeting of the stockholders may be taken without a meeting without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of the minimum number of votes necessary to authorize or take such action at a meeting at which shares entitled to vote thereon were present and voted and copies are delivered to the corporation in the manner prescribed by law.

Section 1.9 Voting of Shares of Certain Holders. Shares of stock of the corporation standing in the name of another corporation, domestic or foreign, may be voted by such officer, agent, or proxy as the by-laws of such corporation may prescribe, or, in the absence of such provision, as the board of directors of such corporation may determine.

Shares of stock of the corporation standing in the name of a deceased person, a minor ward or an incompetent person, may be voted by his administrator, executor, court-appointed guardian or conservator without a transfer of such shares into the name of such administrator, executor, court appointed guardian or conservator. Shares of capital stock of the corporation standing in the name of a trustee or fiduciary may be voted by such trustee or fiduciary.

Shares of stock of the corporation standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his name if authority so to do be contained in an appropriate order of the court by which such receiver was appointed.

##### Table of Contents

A stockholder whose shares are pledged shall be entitled to vote such shares unless in the transfer by the pledgor on the books of the corporation he expressly empowered the pledgee to vote thereon, in which case only the pledgee or its proxy shall be entitled to vote the shares so transferred.

Shares of its own stock belonging to this corporation shall not be voted, directly or indirectly, at any meeting and shall not be counted in determining the total number of outstanding shares at any given time, but shares of its own stock held by the corporation in a fiduciary capacity may be voted and shall be counted in determining the total number of outstanding shares.

Section 1.10 Stockholder Lists. The secretary (or the corporation’s transfer agent or other person authorized by these by-laws or by law) shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. The corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least ten days prior to the meeting, (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting or (ii) during ordinary business hours, at the corporation’s principal executive office. In the event that the corporation determines to make the list available on an electronic network, the corporation may take reasonable steps to ensure that such information is available only to stockholders of the corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible network, and the information required to access such list shall be provided with the notice of the meeting.

Article II.

Board of Directors

Section 2.1 Powers. Except as reserved to the stockholders by law or by the Certificate of Incorporation, the business of the corporation shall be managed under the direction of the board of directors, who shall have and may exercise all of the powers of the corporation. In particular, and without limiting the foregoing, the board of directors shall have the power to issue or reserve for issuance from time to time the whole or any part of the capital stock of the corporation which may be authorized from time to time to such person, for such consideration and upon such terms and conditions as they shall determine, including the granting of options, warrants or conversion or other rights to stock.

Section 2.2 Number of Directors; Qualifications.

Except as otherwise provided by law, by the Certificate of Incorporation or by these by-laws, directors shall hold office until the next annual meeting of stockholders and thereafter until their successors are chosen and qualified. Any director may resign by delivering or mailing postage prepaid a written resignation to the corporation at its principal office or to the chairman of the board, if any, president, secretary or assistant secretary, if any. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event.

Section 2.8 Removal. A director may be removed from office only for cause by vote of the holders of eighty percent (80%) of the voting stock then outstanding.

Section 2.9 Meetings. Regular meetings of the board of directors may be held without call or notice at such times and such places within or without the State of Delaware as the Board may, from time to time, determine, provided that notice of the first regular meeting following any such determination shall be given to directors absent from such determination. A regular meeting of the board of directors shall be held without notice immediately after, and at the same place as, the annual meeting of the stockholders or the special meeting of the stockholders held in place of such annual meeting, unless a quorum of the directors is not then present. Special meetings of the board of directors may be held at any time and at any place designated in the call of the meeting when called by the chairman of the board, the chief executive officer, the president, or a majority of the directors. Members of the board of directors or any committee elected thereby may participate in a meeting of such board or committee by means of a conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other at the same time, and participation by such means shall constitute presence in person at the meeting.

Section 2.10 Notice of Meeting. It shall be sufficient notice to a director to send or give notice (i) by mail at least seventy-two (72) hours before the meeting addressed to such person at his usual or last known business or residence address or (ii) in person, by telephone, facsimile or electronic transmission to the extent provided in Section 2.10 of these by-laws, at least twenty-four (24) hours before the meeting. Notice shall be given by the secretary, or in his absence or unavailability, may be given by any of an assistant secretary, if any, or by the officer or directors calling the meeting. The requirement of notice to any director may be waived by a written waiver of notice signed by the person entitled to notice or a waiver by electronic transmission by the person entitled to notice, executed or transmitted by such person before or after the meeting or meetings, and filed with the records of the meeting, or by attendance at the meeting without protesting prior thereto or at its commencement the lack of notice. A notice or waiver of notice or any waiver of electronic transmission of a directors’ meeting need not specify the purposes of the meeting.

Section 2.11 Agenda. Any lawful business may be transacted at a meeting of the board of directors, notwithstanding the fact that the nature of the business may not have been specified in the notice or waiver of notice of the meeting.

Section 2.12 Quorum. At any meeting of the board of directors, a majority of the directors then in office shall constitute a quorum for the transaction of business. Any meeting may be adjourned by a majority of the votes cast upon the question, whether or not a quorum is present, and the meeting may be held as adjourned without further notice.

Section 2.13 Action at Meeting. Any motion adopted by vote of the majority of the directors present at a meeting at which a quorum is present shall be the act of the board of directors, except where a different vote is required by law, by the Certificate of Incorporation or by these by-laws.

Section 2.14 Action Without Meeting. Any action required or permitted to be taken at any meeting of the Board, or any committee thereof, may be taken without a meeting if all of the members of the Board or committee, as the case may be, consent to the action in writing or by electronic transmission and the writing(s) or electronic transmission(s) are filed with the minutes of proceedings of the Board or committee. Such filing shall be in paper form if the minutes are in paper form and shall be in electronic form if the minutes are maintained in electronic form. Such consent shall be treated for all purposes as a vote of the Board or committee, as the case may be, at a meeting.

Section 2.15 Committees. The board of directors may, by the affirmative vote of a majority of the directors then in office, appoint an executive committee or other committees consisting of one or more directors and may by vote delegate to any such committee some or all of their powers except those which by law, the Certificate of Incorporation or these by-laws they may not delegate. In addition to other committees that the board of directors may designate from time to time, the board of directors shall designate a compensation committee, an audit committee and a nominating and corporate governance committee. In the absence or disqualification of a member of a committee, the members of the committee present and not disqualified, whether or not they constitute a quorum, may by unanimous vote appoint another member of the board of directors to act at the meeting in place of the absence or disqualified member. A committee may create one or more subcommittees, each subcommittee to consist of one or more members of the committee, and delegate to such subcommittee any or all of the powers of the committee. Unless the board of directors shall otherwise provide, any such committee may make rules for the conduct of its business, but unless otherwise provided by the board of directors or such rules, its meetings shall be called, notice given or waived, its business conducted or its action taken as nearly as may be in the same manner as is provided in these by-laws with respect to meetings or for the conduct of business or the taking of actions by the board of directors. The board of directors shall have power at any time to fill vacancies in, change the membership of, or discharge any such committee at any time. The board of directors shall have power to rescind any action of any committee, but no such rescission shall have retroactive effect.

Section 2.16 Continuing Directors. As of the Effective Time (as defined in the Agreement and Plan of Merger, dated May 20, 2007, by and among the corporation, Nor’easter Corp. and Cytyc Corporation (“Cytyc”)), as the same may be amended from time to time (the “Merger Agreement”), the directors of Hologic shall consist of (i) six (6) Continuing Hologic Directors, consisting of four (4) persons designated by the Continuing Hologic Directors, each of whom shall be “independent” (as defined in the rules and regulations governing the requirements of companies listing on the NASDAQ Global Select Market) and two persons who are not independent, and (ii) five (5) Continuing Cytyc Directors, consisting of three (3) persons designated by the Continuing Cytyc Directors, each of whom shall be independent (as defined in the rules and regulations governing the requirements of companies listing on the NASDAQ Global Select Market) and two persons who are not independent.

The terms “Continuing Hologic Directors” and “Continuing Cytyc Directors” shall for purposes of this Section 2.16 mean, respectively, the directors of Hologic or Cytyc, as the case may be, as of the Effective Time who were selected to be directors of Hologic as of the Effective Time by Hologic or Cytyc, as the case may be, prior to the Effective Time, and any additional directors of Hologic who take office after the Effective Time who are nominated, or proposed to the nominating and corporate governance committee of the board of directors, by a majority of the Continuing Hologic Directors or the Continuing Cytyc Directors, as the case may be under clauses (i) and (ii) above.

It shall be the duty of each stockholder to notify the corporation of his post office address.

Section 4.4 Record Date. In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournments thereof, the board of directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the board of directors and which record date shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If no record date is fixed, the record date for determining stockholders entitled to receive notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held.

(b) In order that the corporation may determine the stockholders entitled to express consent to corporate action in writing without a meeting, the board of directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the board of directors, and which record date shall not be more that 10 days after the date upon which the resolution fixing the record date is adopted by the board of directors. Any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the Secretary of the Corporation, request the Board of Directors to fix a record date. The board of directors shall promptly, but in all events within 10 days after the date on which such a request is received, adopt a resolution fixing the record date. If no record date has been fixed by the board of directors within 10 days after the date on which such a request is received, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the board of directors is required by applicable law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation. If no record date has been fixed by the board of directors and prior action by the board of director is required by applicable law, the Certificate of Incorporation, or these Bylaws, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the date on which the board of directors adopts the resolution taking such prior action.

(c) In order that the corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the board of directors may fix a record date, which record date shall not be more than sixty (60) days prior to such action. If no record date is fixed, the record date for determining stockholders for such purpose shall be at the close of business on the day on which the board of directors adopts the resolution relating thereto.

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the board may fix a new record date for the adjourned meeting.

Section 4.5 Transfer Agent and Registrar for Shares of Corporation. The board of directors may appoint a transfer agent and a registrar of the certificates of stock of the corporation. Any transfer agent so appointed shall maintain, among other records, a stockholders’ ledger, setting forth the names and addresses of the holders of all issued shares of stock of the corporation, the number of shares held by each, the certificate numbers representing such shares, and the date of issue of the certificates representing such shares. Any registrar so appointed shall maintain, among other records, a share register, setting forth the total number of shares of each class of shares which the corporation is authorized to issue and the total number of shares actually issued. The stockholders’ ledger and the share register are hereby identified as the stock transfer books of the corporation; but as between the stockholders’ ledger and the share register, the names and addresses of stockholders, as they appear on the stockholders’ ledger maintained by the transfer agent shall be the official list of stockholders of record of the corporation. The name and address of each stockholder of record, as they appear upon the stockholders’ ledger, shall be conclusive evidence of who are the stockholders entitled to receive notice of the meetings of stockholders, to vote at such meetings, to examine a complete list of the stockholders entitled to vote at meetings, and to own, enjoy and exercise any other property or rights deriving from such shares against the corporation. Stockholders, but not the corporation, its directors, officers, agents or attorneys, shall be responsible for notifying the transfer agent, in writing, of any changes in their names or addresses from time to time, and failure to do so will relieve the corporation, its other stockholders, directors, officers, agents and attorneys, and its transfer agent and registrar, of liability for failure to direct notices or other documents, or pay over or transfer dividends or other property or rights, to a name or address other than the name and address appearing in the stockholders’ ledger maintained by the transfer agent.

Section 4.6 Loss of Certificates. In case of the loss, destruction or mutilation of a certificate of stock, a replacement certificate may be issued in place thereof upon such terms as the board of directors may prescribe, including, in the discretion of the board of directors, a requirement of bond and indemnity to the corporation.

Section 4.7 Restrictions on Transfer. Every certificate for shares of stock which are subject to any restriction on transfer, whether pursuant to the Certificate of Incorporation, the by-laws or any agreement to which the corporation is a party, shall have the fact of the restriction noted conspicuously on the certificate and shall also set forth on the face or back either the full text of the restriction or a statement that the corporation will furnish a copy to the holder of such certificate upon written request and without charge.

Section 4.8 Multiple Classes of Stock. The amount and classes of the capital stock and the par value, if any, of the shares, shall be as fixed in the Certificate of Incorporation. At all times when there are two or more classes of stock, the several classes of stock shall conform to the description and the terms and have the respective preferences, voting powers, restrictions and qualifications set forth in the Certificate of Incorporation and these by-laws. Every certificate issued when the corporation is authorized to issue more than one class or series of stock shall set forth on its face or back either (i) the full text of the preferences, voting powers, qualifications and special and relative rights of the shares of each class and series authorized to be issued, or (ii) a statement of the existence of such preferences, powers, qualifications and rights, and a statement that the corporation will furnish a copy thereof to the holder of such certificate upon written request and without charge.

with the Corporation

Any and all of the directors and officers of the corporation, notwithstanding their official relations to it, may enter into and perform any contract or agreement of any nature between the corporation and themselves, or any and all of the individuals from time to time constituting the board of directors of the corporation, or any firm or corporation in which any such director may be interested, directly or indirectly, whether such individual, firm or corporation thus contracting with the corporation shall thereby derive personal or corporate profits or benefits or otherwise; provided, that (i) the material facts of such interest are disclosed or are known to the board of directors or committee thereof which authorizes such contract or agreement; (ii) if the material facts as to such person’s relationship or interest are disclosed or are known to the stockholders entitled to vote thereon, and the contract is specifically approved in good faith by a vote of the stockholders; or (iii) the contract or agreement is fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee thereof, or the stockholders. Any director of the corporation who is interested in any transaction as aforesaid may nevertheless be counted in determining the existence of a quorum at any meeting of the board of directors which shall authorize or ratify any such transaction. This Article shall not be construed to invalidate any contract or other transaction which would otherwise be valid under the common or statutory law applicable thereto.

Article VII.

Indemnification

Section 7.1 Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he is or was a director or officer of the corporation or, while a director or officer of the corporation, is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), where the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, shall be indemnified and held harmless by the corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the corporation to provide broader indemnification rights than permitted prior thereto), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased

to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in Section 7.3 hereof with respect to proceedings to enforce rights to indemnification, the corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the board of directors of the corporation.

Section 7.2 Right to Advancement of Expenses. The right to indemnification conferred in Section 7.1 shall include the right to be paid by the corporation the expenses incurred in defending any proceeding for which such right to indemnification is applicable in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that, if the Delaware General Corporation Law requires, an advancement of expenses incurred by an indemnitee in his capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the corporation of an undertaking (hereinafter an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section or otherwise.

Section 7.3 Right of Indemnitee to Bring Suit. The rights to indemnification and to the advancement of expenses conferred in Section 7.1 and Section 7.2, respectively, shall be contract rights. If a claim under Section 7.1 or Section 7.2 is not paid in full by the corporation within sixty days after a written claim has been received by the corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty days, the indemnitee may at any time thereafter bring suit against the corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (A) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (B) in any suit by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking the corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the Delaware General Corporation Law. Neither the failure of the corporation (including its board of directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the corporation (including its board of directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Section or otherwise shall be on the corporation.

Section 7.4 Non-Exclusivity. The rights of indemnification and to receive advancement of expenses as provided by this Article shall not be deemed exclusive of any other rights to which an indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, these by-laws, any agreement, a vote of stockholders or a resolution of the board of directors, or otherwise. No amendment, alteration, rescission or replacement of this Article or any provision hereof shall be effective as to an indemnitee with respect to any action taken or omitted by such indemnitee in his or her capacity as a director or officer or with respect to any state of facts then or previously existing or any proceeding previously or thereafter brought or threatened based in whole or to the extent based in part upon any such state of facts existing prior to such amendment, alteration, rescission or replacement.

Section 7.5 Insurance. The corporation may maintain, at its expense, an insurance policy or policies to protect itself and any indemnitee, officer, employee or agent of the corporation or another enterprise against liability arising out of this Article or otherwise, whether or not the corporation would have the power to indemnify any such person against such liability under the Delaware General Corporation Law.

Section 7.6 No Duplicative Payment. The corporation shall not be liable under this Article to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that an indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

Section 7.7 Severability. If any provision or provisions of this Article shall be held to be invalid, illegal or unenforceable for any reason whatsoever:

(a) the validity, legality and enforceability of the remaining provisions of this Article (including without limitation, each portion of any Section of this Article containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and

(b) to the fullest extent possible, the provisions of this Article (including, without limitation, each portion of any Section of this Article containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

Section 8.6 Evidence of Authority. A certificate by the secretary or any assistant secretary as to any action taken by the stockholders, directors or any officer or representative of the corporation shall, as to all persons who rely thereon in good faith, be conclusive evidence of such action. The exercise of any power which by law, by the Certificate of Incorporation, or by these by-laws, or under any vote of the stockholders or the board of directors, may be exercised by an officer of the corporation only in the event of absence of another officer or any other contingency shall bind the corporation in favor of anyone relying thereon in good faith, whether or not such absence or contingency existed.

Section 1.1 Purpose.

The purpose of the Hologic, Inc.

Section 1.2 Administration of the Plan.

The Plan shall be administered by the Compensation Committee (the “Compensation Committee”) appointed by the Board of Directors of the Company (the “Board”), consisting of at least such number of directors as is required from time to time to satisfy the requirements of the exception under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), for “qualified performance-based compensation.” In addition, each such Compensation Committee member shall satisfy the qualification requirements of Section 162(m) of the Code (“Section 162(m)”), as it may be amended from time to time. The Compensation Committee shall adopt such rules as it may deem appropriate in order to carry out the purpose of the Plan. All questions of interpretation, administration and application of the Plan shall be determined by a majority of the members of the Compensation Committee then in office, except that the Compensation Committee may authorize any one or more of its members, or any officer of the Company, to execute and deliver documents on behalf of the Compensation Committee. The determination of such majority shall be final and binding in all matters relating to the Plan. Subject to the terms of this Plan, the Compensation Committee shall have authority to determine the terms and conditions of all Awards granted under the Plan.

With respect to any restrictions in the Plan that are based on the requirements of Section 162(m) or any other applicable law, rule or restriction, to the extent that any such restrictions are no longer required, the Compensation Committee shall have the sole discretion and authority to grant Awards that are not subject to such restrictions and/or to waive any such restrictions with respect to outstanding Awards.

Section 1.3 Eligibility.

The Compensation Committee may designate as participants, and may grant Awards to, employees of the Company or one of its subsidiaries or divisions, including without limitation those employees that are “covered employees” as such term is defined under Section 162(m) and the regulations and other interpretative guidance issued thereunder. As currently defined, a “covered employee” is the Company’s Chief Executive Officer (or an individual acting in such capacity) and the three other most highly compensated executive officers of the Company (other than its principal financial officer) for the Company’s taxable year.

The Compensation Committee shall designate Plan participants and establish the Performance Targets and the Target Awards for each performance period not later than ninety days after the start of such period; provided, however, that, Performance Targets and Target Awards shall in no event be established after 25% of a performance period has elapsed

Section 2.2 Limitation on Awards.

The aggregate amount of all Awards to be received by any participant under the Plan for any performance period shall not exceed the amount determined by multiplying such participant’s Salary by a factor of four (4).

Section 2.3 Determination of Award.

The Compensation Committee shall, promptly after the date on which the necessary financial or other information for a particular performance period becomes available, certify whether the Performance Targets have been achieved in the manner required by Section 162(m). If the Performance Targets have been achieved, the Awards for such performance period shall have been earned, except that the Compensation Committee may, in its sole and absolute discretion, reduce the amount of any Award to reflect the Compensation Committee’s assessment of the participant’s individual performance or for any other reason. Subject to Section 2.4, such Awards shall become payable in cash as promptly as practicable thereafter.

If (i) the Company or any subsidiary terminates a participant’s employment other than for “cause,” (ii) a participant terminates his or her employment for “good reason,” (iii) a participant becomes “permanently disabled” or (iv) a participant dies during a performance period, such participant or his or her estate, if applicable, shall be awarded, unless his or her employment agreement provides otherwise, a pro rata portion of the amount of the Award earned for such performance period, except that the Compensation Committee may, in its sole discretion, reduce the amount of such Award to reflect the Compensation Committee’s assessment of such participant’s individual performance prior to the applicable termination event or for any other reason. Unless otherwise specifically defined by an employment agreement or a benefit plan document, determinations with respect to whether a participant’s employment has been terminated for cause, for good reason or due to permanent disability shall be made by the Compensation Committee in its sole discretion

the effect, as determined by the Compensation Committee in its sole and absolute discretion, of distorting the applicable Performance Targets, including, without limitation, changes in accounting standards, the Compensation Committee may, to the extent consistent with Section 162(m), adjust or modify, as determined by the Compensation Committee in its sole and absolute discretion, the calculation of Economic Value Added; Earnings Before Interest, Taxes, Depreciation and Amortization; Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization; Earnings Before Interest and Taxes; Cash Flow; Earnings Per Share; Operating Income; Adjusted Operating Income; Operating Income Before Income Taxes; Adjusted Income Before Income Taxes; Net Income; Adjusted Net Income; Operating Margin; Ratio of Debt to Stockholder’s Equity; Return on Equity; Return on Assets; Revenue; and Total Shareholder Return, each as defined on Exhibit A, to the extent necessary to prevent reduction or enlargement of participants’ Awards under the Plan for such performance period attributable to such transaction, circumstance or event.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Section 145 of the General Corporation Law of the State of Delaware, or the DGCL, generally provides that all directors and officers (as well as other employees and individuals) may be indemnified against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with certain specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation, or a derivative action), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard of care is applicable in the case of derivative actions, except that indemnification extends only to expenses (including attorneys’ fees) incurred in connection with defense or settlement of an action, and the DGCL requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Hologic’s certificate of incorporation currently provides, that Hologic may indemnify to the fullest extent permitted by the DGCL any director or officer who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding. Article 10 of Hologic’s certificate of incorporation eliminates the personal liability of Hologic’s directors to Hologic or Hologic’s stockholders for monetary damages for breach of fiduciary duty to the extent permitted by the DGCL. Article VII of Hologic’s current bylaws provides that Hologic may indemnify its officers and directors to the extent permitted by Delaware General Corporation Law. Hologic has also entered into indemnification agreements with each of its directors. The indemnification agreements are intended to provide the maximum protection permitted by Delaware law with respect to indemnification of directors. Hologic may also enter into similar agreements with certain of its officers who are not also directors. The effect of these provisions is to permit indemnification by Hologic for liabilities arising under the Securities Act of 1933, as amended. Hologic also maintains directors and officers liability insurance. Upon completion of the merger, Hologic’s bylaws will provide that Hologic shall indemnify its directors and officers for any proceedings in which they are involved by reason of the fact that they are or were a director or officer of the corporation to the fullest extent permitted by Delaware law.

Section 145 of the DGCL also provides that the rights conferred thereby are not exclusive of any other right to which any person may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, and permits a corporation to advance expenses to or on behalf of a person entitled to be indemnified, subject to, in the case of officers and directors, receipt of an undertaking to repay the amounts advanced if it is determined that the person is not entitled to be indemnified.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for any breach of the director’s duty of loyalty to the corporation or its stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions, or for any transaction from which the director derived an improper personal benefit. Hologic’s certificate of incorporation provides that no director will be liable to Hologic or its stockholders for monetary damages for breach of fiduciary duty as a director, subject to the statutory exceptions.

Item 22. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post- effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference into the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-3

##### Table of Contents

(c) (1) The undersigned registrant undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) The undersigned registrant undertakes that every prospectus (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(e) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(f) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
