ABOUT THIS PROSPECTUS

This prospectus provides you with a general description of the securities we and/or any selling stockholders may offer. Each time we and/or any selling stockholders sell securities under this shelf registration, a prospectus supplement will be provided that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus.

You should not assume that the information contained in this prospectus and the accompanying prospectus supplement is accurate on any date subsequent to the date set forth on the front of the document or that any information we have incorporated by reference is correct on any date subsequent to the date of the document incorporated by reference, even though this prospectus and any accompanying prospectus supplement is delivered or securities are sold on a later date.

FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein may contain “forward-looking statements” within the meaning of the federal securities laws. All statements other than statements of historical fact included in this prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein are forward-looking statements. These statements relate to analyses and other information, which are based on forecasts of future results or events and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies. We claim the protection of The Private Securities Litigation Reform Act of 1995 for all forward-looking statements in this prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein.

These forward-looking statements are identified by the use of terms and phrases such as “anticipate,” “assume,” “believe,” “estimate,” “expect,” “goal,” “intend,” “plan,” “potential,” “predict,” “project,” “target” and similar terms and phrases or future or conditional verbs such as “could,” “may,” “should,” “will,” and “would.” However, these words are not the exclusive means of identifying such statements. Although we believe that our plans, intentions and other expectations reflected in or suggested by such forward-looking statements are reasonable, we cannot assure you that we will achieve those plans, intentions or expectations. All forward-looking statements are subject to risks and uncertainties that may cause actual results or events to differ materially from those that we expected.

Important factors that could cause actual results or events to differ materially from our expectations, or cautionary statements, are disclosed under the section entitled “Risk Factors” included in our most recent Annual Report on Form 10-K and from time to time in our subsequent Quarterly Reports on Form 10-Q and our other SEC filings. All written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by the cautionary statements contained in the section entitled “Risk Factors” included in our most recent Annual Report on Form 10-K as well as other cautionary statements that are made from time to time in our other SEC filings and public communications. You should evaluate all forward-looking statements made in this prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein in the context of these risks and uncertainties.

We caution you that the important factors referenced above may not reflect all of the factors that could cause actual results or events to differ from our expectations. In addition, we cannot assure you that we will realize the results or developments we expect or anticipate or, even if substantially realized, that they will result in the consequences or affect us or our operations in the way we expect. The forward-looking statements included or incorporated by reference herein are made only as of the date hereof or, with respect to any documents incorporated by reference, available at the time such document was prepared or filed with the SEC.

GUARANTOR DISCLOSURES

CDW Corporation and certain of CDW LLC’s direct and indirect, wholly-owned, domestic subsidiaries (the “Guarantor Subsidiaries”) may guarantee debt securities of CDW LLC and CDW Finance Corporation as described in “Description of Debt Securities and Guarantees” in this prospectus and as further described in an applicable prospectus supplement. Any such guarantees by CDW Corporation and the Guarantor Subsidiaries will be joint and several, and full and unconditional; provided that guarantees by the Guarantor Subsidiaries are subject to certain customary release provisions contained in the indentures.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we will use the net proceeds from the sale of the securities for general corporate purposes, which may include capital expenditures, working capital, acquisitions, investments and the repayment of indebtedness. Pending these uses, the net proceeds may also be temporarily invested in short- and medium-term investments, including, but not limited to, marketable securities.

We will not receive any proceeds from the sale of common stock by any selling stockholders.

##### Table of Contents

DESCRIPTION OF CAPITAL STOCK

The following summary of certain provisions of our capital stock does not purport to be complete and is subject to our amended and restated certificate of incorporation (the “Certificate of Incorporation”), our amended and restated bylaws (the “Bylaws”) and provisions of applicable law. Copies of our Certificate of Incorporation and Bylaws are incorporated by reference into the registration statement, of which this prospectus is a part.

Authorized Capital Stock

Our authorized capital stock consists of 1,000,000,000 shares of common stock, par value $0.01 per share, and 100,000,000 shares of preferred stock, par value $0.01 per share.

Common Stock Voting Rights

Each holder of common stock is entitled to one vote per share on each matter submitted to a vote of stockholders. Our Bylaws provide that the presence, in person or by proxy, of holders of a majority in voting power of the outstanding capital stock entitled to vote at a stockholders’ meeting shall constitute a quorum. When a quorum is present, the affirmative vote of the majority of voting power of capital stock present in person or represented by proxy at the meeting and entitled to vote on the subject matter is required to take action, unless otherwise specified by law or our Certificate of Incorporation. There are no cumulative voting rights.

Common Stock Dividend Rights

Each holder of shares of common stock is entitled to receive such dividends and other distributions in cash, stock or property as may be declared by our board of directors (“Board”) from time to time out of our assets or funds legally available for dividends or other distributions. These rights are subject to the preferential rights of any other class or series of our preferred stock that we may designate and issue in the future.

The Delaware General Corporation Law (the “DGCL”) permits a corporation to declare and pay dividends out of “surplus” or, if there is no “surplus,” out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. “Surplus” is defined as the excess of the net assets of the corporation over the amount determined to be the capital of the corporation by the board of directors. The capital of the corporation is typically calculated to be (and cannot be less than) the aggregate par value of all issued shares of capital stock. Net assets equals the fair value of the total assets minus total liabilities. The DGCL also provides that dividends may not be paid out of net profits if, after the payment of the dividend, remaining capital would be less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets.

Declaration and payment of any dividend will be subject to the discretion of the Board. The time and amount of dividends will be dependent upon our results of operations, financial condition, business prospects, capital requirements, contractual restrictions (including in current or future agreements governing our indebtedness), restrictions imposed by applicable law, tax considerations and other factors that the Board deems relevant.

Since the fourth quarter of 2013, we have paid a quarterly cash dividend on our common stock and we currently expect to continue to pay a cash dividend on our common stock. However, any determination to pay dividends in the future will be at the discretion of our board of directors.

Other Rights

Each holder of common stock is subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that we may designate and issue in the future. Holders of common stock will have no preemptive, conversion or other rights to subscribe for additional shares.

5

##### Table of Contents

Liquidation Rights

In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, holders of our common stock would be entitled to share ratably in our assets that are legally available for distribution to stockholders after payment of our debts and other liabilities. If we have any preferred stock outstanding at such time, holders of the preferred stock may be entitled to distribution and/or liquidation preferences. In either such case, we must pay the applicable distribution to the holders of our preferred stock before we may pay distributions to the holders of our common stock.

Preferred Stock

The Board has the authority to issue shares of preferred stock from time to time on terms it may determine, to divide shares of preferred stock into one or more series and to fix the designations, preferences, privileges and restrictions of preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference, sinking fund terms and the number of shares constituting any series or the designation of any series to the fullest extent permitted by the DGCL. The issuance of our preferred stock could have the effect of decreasing the trading price of our common stock, restricting dividends on our capital stock, diluting the voting power of our common stock, impairing the liquidation rights of our capital stock, or delaying or preventing a change in control of our company. At present, we have no plans to issue preferred stock.

Anti-Takeover Effects of the Certificate of Incorporation and Bylaws

The Certificate of Incorporation and Bylaws contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with the Board, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they also give the Board the power to discourage acquisitions that some stockholders may favor.

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock will make it possible for the Board to issue preferred stock with super voting, special approval, dividend or other rights or preferences on a discriminatory basis that could impede the success of any attempt to acquire us. These and other provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of our company.

Stockholder Action by Written Consent

The Certificate of Incorporation provides that any action required or permitted to be taken by our stockholders may be effected only at a duly called annual or special meeting of the stockholders and cannot be taken by written consent in lieu of a meeting.

Special Meeting of Stockholders and Advance Notice Requirements for Stockholder Proposals

The Certificate of Incorporation and Bylaws provide that, except as otherwise required by law, special meetings of the stockholders can only be called (i) by or at the direction of the Board pursuant to a written resolution adopted by the affirmative vote of the majority of the total number of directors that we would have if there were no vacancies or (ii) subject to the requirements and limitations of the Bylaws, by the Secretary, the Chair of the Board or the Board of Directors upon the written request of one or more stockholders entitled to cast on the matter(s) to be brought before a special meeting requested by one or more stockholders pursuant to Section 3 of the Bylaws not less than twenty five percent (25%) of the voting power of all outstanding shares as of the date of the request, which request complies with the procedures for calling a special meeting of

6

##### Table of Contents

stockholders as set forth in the Bylaws, as may be amended from time to time. Any business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of the meeting.

In addition, the Bylaws require advance notice procedures for stockholder proposals to be brought before an annual meeting of the stockholders, including the nomination of directors. Stockholders at an annual meeting may only consider the proposals specified in the notice of meeting or brought before the meeting by or at the direction of the Board, or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered a timely written notice, in proper form to our secretary, of the stockholder’s intention to bring such business before the meeting.

These provisions could have the effect of delaying until the next stockholder meeting any stockholder actions, even if they are favored by the holders of a majority of our outstanding voting securities.

Business Combinations with Interested Stockholders

We are subject to Section 203 of the DGCL, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the corporation’s voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner.

Exclusive Jurisdiction of Certain Actions

The Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar exclusive jurisdiction provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any action, a court could find the exclusive jurisdiction provision contained in the Certificate of Incorporation to be inapplicable or unenforceable in such action.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Listing

Our common stock is listed on the Nasdaq Global Select Market under the trading symbol “CDW.”

DESCRIPTION OF DEPOSITARY SHARES

The following description of the depositary shares and the terms of the deposit agreement is a summary. It summarizes only those aspects of the depositary shares and those portions of the deposit agreement that we believe will be most important to your decision to invest in our depositary shares. There may be other provisions in the deposit agreement that are also important to you. You should read the deposit agreement for a full description of the terms of the depositary shares. The form of the deposit agreement will be filed or incorporated by reference as an exhibit to the registration statement of which this prospectus is a part.

The particular terms of the depositary shares offered by any prospectus supplement and the extent to which the general provisions described below may apply to such depositary shares will be outlined in the applicable prospectus supplement.

General

We may elect to offer fractional interests in preferred shares, rather than offer whole preferred shares. If we choose to do this, we will provide for the issuance by a depositary to the public of receipts for depositary shares. Each depositary share will represent fractional interests of a particular series of preferred shares.

The shares of any series of preferred shares underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company, which we will select. The bank or trust company must have its principal office in the United States and a combined capital and surplus of at least $50,000,000. The prospectus supplement relating to a series of depositary shares will state the name and address of the depositary. Unless otherwise provided by the deposit agreement, each owner of depositary shares will be entitled, in proportion to the applicable fractional interests in preferred shares underlying the depositary shares, to all the rights and preferences of the preferred stock underlying the depositary shares including dividend, voting, redemption, conversion and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional interests in shares of the related series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received in respect of preferred shares to the record holders of depositary shares relating to the preferred shares in proportion to the numbers of the depositary shares owned by the holders on the relevant record date. The depositary will distribute only an amount, however, that can be distributed without attributing to any holder of depositary shares a fraction of one cent, and any balance not so distributed will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the record holders of depositary shares entitled to it, unless the depositary determines that it is not feasible to make the distribution. If this happens, the depositary may, with our approval, sell the property and distribute the net sale proceeds to the holders. The deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights that we offer to holders of the preferred stock will be made available to the holders of depositary shares.

Redemption of Depositary Shares

If a series of the preferred shares underlying the depositary shares is redeemed in whole or in part, the depositary shares will be redeemed from the redemption proceeds received by the depositary. The depositary will

8

##### Table of Contents

mail notice of redemption not less than 30, and not more than 60, days before the date fixed for redemption to the record holders of the depositary shares to be redeemed at their addresses appearing in the depositary’s books. The redemption price for each depositary share will be equal to the applicable fraction of the redemption price for each share payable with respect to the series of the preferred shares. Whenever we redeem preferred shares held by the depositary, the depositary will redeem on the same redemption date the number of depositary shares relating to the preferred shares so redeemed. If less than all of the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionally as may be determined by the depositary.

After the date fixed for redemption, the depositary shares called for redemption will no longer be considered outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the cash, securities or other property payable upon the redemption and any cash, securities or other property to which the holders of the redeemed depositary shares were entitled upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

The amount distributed in any of the foregoing cases will be reduced by any amount required to be withheld by us or the depositary on account of any taxes.

Voting the Preferred Shares

Upon receipt of notice of any meeting at which the holders of the preferred shares are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary shares relating to the preferred shares. Each record holder of depositary shares on the record date, which will be the same date as the record date for the preferred shares, will be entitled to instruct the depositary how to exercise the voting rights pertaining to the number of preferred shares underlying the holder’s depositary shares. The depositary will endeavor, to the extent practicable, to vote the number of preferred shares underlying the depositary shares in accordance with these instructions, and we will agree to take all action which the depositary may consider necessary in order to enable the depositary to vote the shares. The depositary will abstain from voting preferred shares to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred shares.

Amendment and Termination of Depositary Agreement

We may enter into an agreement with the depositary at any time to amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement. However, the holders of a majority of the depositary shares must approve any amendment which materially and adversely alters the rights of the existing holders of depositary shares. We or the depositary may terminate the deposit agreement only if (a) all outstanding depositary shares issued under the agreement have been redeemed or (b) a final distribution in connection with any liquidation, dissolution or winding up has been made to the holders of the depositary shares.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will also pay charges of the depositary in connection with the initial deposit of the preferred shares and any redemption of the preferred shares. Holders of depositary shares will pay transfer and other taxes and governmental charges and such other charges as are expressly provided in the deposit agreement to be for their accounts.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to resign, and we may at any time remove the depositary. Any resignation or removal will take effect when a successor depositary has been

9

##### Table of Contents

appointed and has accepted the appointment. Appointment must occur within 60 days after delivery of the notice of resignation or removal. The successor depositary must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

Miscellaneous

The depositary will forward to the holders of depositary shares all reports and communications that we deliver to the depositary and that we are required to furnish to the holders of the preferred shares. Neither the depositary nor we will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the deposit agreement. The obligations of us and the depositary under the deposit agreement will be limited to performance in good faith of their duties under the agreement and they will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred shares unless the holders provide them with satisfactory indemnity. They may rely upon written advice of counsel or accountants, or information provided by persons presenting preferred stock for deposit, holders of depositary shares or other persons believed to be competent and on documents they believe to be genuine.

General

We may issue warrants to purchase debt or equity securities. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities.

##### Table of Contents

| • |  | the maximum or minimum number of warrants which may be exercised at any time; and

| • |  | information with respect to book-entry procedures, if any.

Exercise of Warrants

Each warrant will entitle the holder of warrants to purchase for cash the amount of debt or equity securities, at the exercise price stated or determinable in the prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the prospectus supplement relating to the warrants, unless otherwise specified in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the prospectus supplement relating to the warrants. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as possible, forward the debt or equity securities that the warrant holder has purchased. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants.

DESCRIPTION OF SUBSCRIPTION RIGHTS

This section describes the general terms of the subscription rights to purchase common stock or other securities that we may offer to stockholders using this prospectus. The following description is only a summary and does not purport to be complete. You must look at the applicable forms of subscription agent agreement and subscription certificate for a full understanding of all terms of any series of subscription rights. The forms of the subscription agent agreement and the subscription certificate will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

General

Subscription rights may be issued independently or together with any other security and may or may not be transferable. As part of the rights offering, we may enter into a standby underwriting or other arrangement under which the underwriters or any other person would purchase any securities that are not purchased in such rights offering. If we issue subscription rights, they may be governed by a separate subscription agent agreement that we will sign with a bank or trust company, as rights agent, that will be named in the applicable prospectus supplement. The rights agent will act solely as our agent and will not assume any obligation to any holders of rights certificates or beneficial owners of rights.

In general, a right entitles the holder to purchase for cash a specific number of shares of common stock or other securities at a specified exercise price. The rights are normally issued to stockholders as of a specific record date, may be exercised only for a limited period of time and become void following the expiration of such period. If we determine to issue subscription rights, we will accompany this prospectus with a prospectus supplement that will describe, among other things:

| • |  | the record date for stockholders entitled to receive the rights;

| • |  | the number of shares of common stock or other securities that may be purchased upon exercise of each right;

| • |  | the exercise price of the rights;

| • |  | whether the rights are transferable;

| • |  | the period during which the rights may be exercised and when they will expire;

| • |  | the steps required to exercise the rights;

| • |  | the price, if any, for the subscription rights;

| • |  | the number of subscription rights issued;

| • |  | the terms of the shares of common stock or shares of preferred stock, debt securities or depositary shares;

| • |  | the extent to which the subscription rights are transferable;

| • |  | if applicable, the material terms of any standby underwriting or other arrangement entered into by us in connection with the offering of subscription rights;

| • |  | the other terms of the subscription rights, including the terms, procedures and limitations relating to the exercise of the subscription rights;

| • |  | whether the rights include “oversubscription rights” so that the holder may purchase more securities if other holders do not purchase their full allotments;

| • |  | whether we intend to sell the shares of common stock or other securities that are not purchased in the rights offering to an underwriter or other purchaser under a contractual “standby” commitment or other arrangement; and

| • |  | any applicable United States federal income tax considerations.

13

##### Table of Contents

DESCRIPTION OF DEBT SECURITIES AND GUARANTEES

The following description discusses the general terms and provisions of the debt securities that we may offer under this prospectus. The debt securities may be issued as senior debt securities or subordinated debt securities. The indebtedness represented by the senior debt securities will rank equally with all of our other unsecured and unsubordinated debt. The senior debt securities will, however, be subordinated in right of payment to all of our secured indebtedness to the extent of the value of the assets securing that indebtedness. The indebtedness represented by the subordinated debt securities will rank junior and be subordinate in right of payment to the prior payment in full of our senior debt, to the extent and in the manner set forth in the applicable prospectus supplement for the securities.

Unless otherwise specified in the applicable prospectus supplement, the senior debt securities and the subordinated debt securities will be issued by CDW LLC and CDW Finance Corporation and will be guaranteed by CDW Corporation and/or one or more of our domestic subsidiaries. The senior debt securities and the subordinated debt securities will be issued under indenture(s) between us and one or more United States banking institutions. Unless otherwise specified in the applicable prospectus supplement, the trustee under the indentures will be U.S. Bank National Association.

The form of the indenture is filed as an exhibit to the registration statement of which this prospectus is a part. The indenture is subject to and governed by the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act, and may be supplemented or amended from time to time following its execution. The form of the indenture gives us broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of debt securities and the extent, if any, to which the particular terms of the issue modify the terms of the form of indenture will be described in the prospectus supplement relating to such series of debt securities.

CDW LLC and CDW Finance Corporation may also issue additional senior debt securities under the indenture governing their 5.500% Senior Notes due December 2024 (the “December 2024 Senior Notes”), the indenture governing their 4.125% Senior Notes due May 2025 (the “May 2025 Senior Notes”), the indenture governing their 2.670% Senior Notes due December 2026 (the “December 2026 Senior Notes”), the indenture governing their 4.250% Senior Notes due April 2028 (the “April 2028 Senior Notes”), the indenture governing their 3.276% Senior Notes due December 2028 (the “December 2028 Senior Notes”), the indenture governing their 3.250% Senior Notes due February 2029 (the “February 2029 Senior Notes”), or the indenture governing their 3.569% Senior Notes due December 2031 (the “December 2031 Senior Notes”), which will have terms substantially identical in all material respects to the December 2024 Senior Notes, the May 2025 Senior Notes, the December 2026 Senior Notes, the April 2028 Senior Notes, the December 2028 Senior Notes, the February 2029 Senior Notes, or the December 2031 Senior Notes, respectively, and which will be guaranteed by CDW Corporation and certain of our domestic subsidiaries that are guarantors under our senior unsecured term loan facility. The notes issued under any such series and any additional notes issued under such series will be treated as a single class for all purposes of the indenture governing such series. The indentures governing the December 2024 Senior Notes, the May 2025 Senior Notes, the December 2026 Senior Notes, the April 2028 Senior Notes, the December 2028 Senior Notes, the February 2029 Senior Notes and the December 2031 Senior Notes are filed as exhibits to the registration statement of which this prospectus is a part.

The following summary describes selected provisions of the form of indenture. This summary does not describe every aspect of the debt securities or the indenture and is subject to, and qualified in its entirety by reference to, all the provisions of the indenture, including the terms defined in the indenture. We urge you to read the indenture in its entirety. This summary is also subject to, and qualified in its entirety by reference to, the description of the particular debt securities in the applicable prospectus supplement.

General

The indenture provides that we will be able to issue an unlimited aggregate principal amount of debt securities under the indentures, in one or more series, and in any currency or currency units. We are not required to issue all debt securities of one series at the same time and, unless otherwise provided, we may reopen a series, without the consent of the holders of the debt securities of that series, for issuances of additional debt securities of that series.

The general provisions of the indentures do not contain any provisions that would limit our ability or the ability of our subsidiaries to incur indebtedness or that would afford holders of our debt securities protection in the event of a highly leveraged or similar transaction involving us or any of our subsidiaries. Please refer to the applicable prospectus supplement for information with respect to any deletions from, modifications of or

16

##### Table of Contents

additions to, the events of default described below that are applicable to the offered debt securities or any covenants or other provisions providing event risk or similar protection.

Payment

Unless we state otherwise in the applicable prospectus supplement, we will pay interest on a debt security on each interest payment date to the person in whose name the debt security is registered as of the close of business on the regular record date relating to the interest payment date.

Unless we state otherwise in the applicable prospectus supplement, we will pay principal of and any premium on the debt securities at stated maturity, upon redemption or otherwise, upon presentation of the debt securities at the office of the trustee, as our paying agent, or at other designated places. Any other paying agent initially designated for the debt securities of a particular series will be identified in the applicable prospectus supplement.

Forms, Transfers and Exchanges

The debt securities of each series will be issued only in fully registered form, without interest coupons. Unless we state otherwise in the applicable prospectus supplement, the debt securities will be issued in denominations of $2,000 each and integral multiples of $1,000 in excess of $2,000.

Subject to the terms of the indenture and the limitations applicable to global securities, you may exchange or transfer debt securities at the corporate trust office of the trustee or at any other office or agency maintained by us for that purpose, without the payment of any service charge, except for any tax or governmental charge.

Global Securities

The debt securities of any series may be issued, in whole or in part, by one or more global certificates that will be deposited with the depositary identified in the applicable prospectus supplement.

No global security may be exchanged in whole or in part for the debt securities registered in the name of any person other than the depositary for that global security or any nominee of that depositary except in the following circumstances or as otherwise provided in the applicable prospectus supplement. The depositary may discontinue providing its services as depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, certificates are required to be printed and delivered. In addition, we may decide to discontinue use of the system of book-entry-only transfers through a depositary. In that event, certificates will be printed and delivered to the depositary.

Unless otherwise stated in any prospectus supplement, The Depository Trust Company (“DTC”) will act as depositary. Beneficial interests in global certificates will be shown on, and transfers of global certificates will be effected only through records maintained by DTC and its participants.

Events of Default

Unless otherwise specified in the applicable prospectus supplement, an event of default occurs with respect to debt securities of any series if:

| • |  | we default in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any, on the debt securities;

| • |  | we default in the payment when due of interest on or with respect to the debt securities and such default continues for a period of 30 days;

17

##### Table of Contents

| • |  | we default in the performance of, or breach any covenant, warranty or other agreement contained in, the indenture (other than a default in the performance or breach of a covenant, warranty or agreement which is specifically dealt with in the immediately preceding two bullets) and such default or breach continues for a period of 60 days after the notice specified below or 90 days with respect to the covenant described under Section 4.03 of the indenture;

| • |  | certain events of bankruptcy affecting us;

| • |  | if Article X of the indenture is made applicable with respect to such debt securities, the guarantee of CDW Corporation ceases to be in full force and effect (except as contemplated by the terms hereof); or

| • |  | CDW Corporation denies or disaffirms its obligations under any indenture or guarantee, other than by reason of the release of the guarantee in accordance with the terms of any indenture.

If an event of default (other than an event of default with respect to certain events of bankruptcy affecting us) shall occur and be continuing, the trustee acting at the written direction of the holders of at least 25% in aggregate principal amount of the then total outstanding debt securities of an affected series may declare the principal of the debt securities and any accrued interest on the debt securities to be due and payable by notice in writing to us and the trustee specifying the respective event of default and that it is a “notice of acceleration,” and the same shall become immediately due and payable.

Upon such declaration of acceleration, the aggregate principal amount of, and accrued and unpaid interest, if any, on all of the outstanding debt securities shall ipso facto become and be immediately due and payable in cash without any declaration or other act on the part of the trustee or any holder of the debt securities. After such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of such outstanding debt securities may, under certain circumstances, rescind and annul such acceleration if all events of default, other than the nonpayment of accelerated principal of or interest on such debt securities, have been cured or waived as provided in the indenture.

The holders of a majority in aggregate principal amount of the debt securities then outstanding by written notice to the trustee may waive any existing default or event of default and its consequences:

| • |  | if the rescission would not conflict with any judgment or decree;

| • |  | if all existing events of default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

| • |  | to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

| • |  | if we have paid the trustee its reasonable compensation and reimbursed the trustee for its expenses, disbursements and advances; and

| • |  | in the event of the cure or waiver of an event of default of the type related to certain events of bankruptcy affecting us, the trustee shall have received an officers’ certificate and an opinion of counsel that such event of default has been cured or waived.

No such rescission shall affect any subsequent default or impair any right consequent thereto.

If an event of default of the type related to certain events of bankruptcy affecting us with respect to us occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest, if any, on all of the outstanding debt securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of the securities.

No holder of any debt security will have any right to institute any proceeding with respect to the debt securities or for any remedy thereunder, unless such holder shall have previously given the trustee written notice

18

##### Table of Contents

of a continuing event of default and unless also the holders of at least 25% in aggregate principal amount of the then outstanding debt securities shall have made written request, and offered reasonable indemnity satisfactory to the trustee, to the trustee to institute such proceeding as trustee, and the trustee shall not have received from the holders of a majority in aggregate principal amount of the outstanding debt securities a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a holder of a debt security for enforcement of payment of the principal of (and premium, if any) or interest on such debt security on or after the respective due dates expressed in such debt security.

The holders of not less than a majority in aggregate principal amount of the issued and then outstanding debt securities of the affected series by notice to the trustee may on behalf of the holders of all of the debt securities waive any existing default or event of default under the indenture, and its consequences, except a default in the payment of the principal of, premium, if any, or interest on such debt securities. Upon such waiver such default shall cease to exist with respect to the applicable series, and any event of default arising therefrom shall be deemed to have been cured with respect to the applicable series for every purpose of this indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Holders of the debt securities may not enforce the indenture or such debt securities except as provided in such indenture and under the Trust Indenture Act. Subject to the provisions of the indenture relating to the duties of the trustee, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of any of the holders of the debt securities, unless such holders have offered to the trustee reasonable indemnity satisfactory to the trustee. Subject to all provisions of the indenture and applicable law, the holders of a majority in aggregate principal amount of the then outstanding debt securities of a series issued under the Indenture have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee.

We are required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any default or event of default, we are required to promptly deliver to the trustee a statement specifying such default or event of default (unless such default or event of default has been cured prior to such time).

Merger or Consolidation

The indenture provides that we may not consolidate or merge with or into another person, whether or not we are the surviving entity, and that we may not sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of our properties and assets in one or more related transactions, to another person, unless:

| • |  | we are the surviving corporation; or the person formed by or surviving such consolidation or merger (if other than us) or to which such sale, assignment, transfer, conveyance, lease or other disposition has been made is a corporation or limited liability company organized or existing under the laws of the United States, any state of the United States, the District of Columbia or any territory thereof;

| • |  | the successor company (if other than us) assumes all of our obligations under the debt securities and the indenture pursuant to agreements reasonably satisfactory to the trustee;

| • |  | immediately after such transaction, no default or event of default exists; and

| • |  | each guarantor (except if it is party to the transactions described above, in which case the second bullet above shall apply) shall have by supplemental indenture confirmed that its guarantee shall apply to such person’s obligations under the debt securities and the indenture.

Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of our assets or a guarantor in accordance with the indenture, the successor corporation formed shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger,

19

##### Table of Contents

| • |  | make any change to or modify the ranking of the debt securities that would adversely affect the holders of debt securities; or

Legal Defeasance and Covenant Defeasance

The indenture provides that we may, at our option and at any time, elect to have all of our obligations and the obligations of the applicable guarantors discharged with respect to any outstanding debt securities issued under the indenture, subject to the terms and conditions as specified in the applicable prospectus supplement, except for:

| • |  | the rights of holders of outstanding debt securities issued thereunder to receive payments in respect of the principal of, premium, if any, and interest on such debt securities when such payments are due solely out of the trust referred to below;

| • |  | our obligations with respect to the debt securities issued thereunder concerning issuing temporary debt securities, registration of such debt securities, mutilated, destroyed, lost or stolen debt securities and the maintenance of an office or agency for payment and money for security payments held in trust;

| • |  | the rights, powers, trusts, duties and immunities of the trustee, and our obligations in connection therewith; and

| • |  | the legal defeasance provisions of the indenture.

In addition, we may, at our option and at any time, elect to have our obligations and the obligations of the guarantors released with respect to certain covenants that are described in the indenture and thereafter any omission to comply with those covenants will not constitute a default or event of default with respect to the debt securities issued thereunder. In the event that a covenant defeasance occurs, certain events (not including nonpayment, bankruptcy, receivership, rehabilitation and insolvency events of ours) described under “—Events of Default” will no longer constitute an event of defaults with respect the debt securities issued under the indenture.

In order to exercise either legal defeasance or covenant defeasance under the indenture:

| • |  | we must irrevocably deposit with the trustee, in trust, for the benefit of the holders of the debt securities of such series, cash in U.S. dollars, non-callable U.S. government securities, or a combination of cash in U.S. dollars and non-callable U.S. government securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, premium, if any, and interest due on the outstanding debt securities of such series (calculated on the cash interest rate, if applicable) issued thereunder on the stated

21

##### Table of Contents

| maturity date or on the applicable redemption date, as the case may be, of such principal, premium, if any, or interest on such debt securities and we must specify whether such debt securities are being defeased to maturity or to a particular redemption date;

| • |  | in the case of legal defeasance, we shall have delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that, subject to customary assumptions and exclusions, (a) we have received from, or there has been published by, the United States Internal Revenue Service a ruling or (b) since the issuance of the debt securities of such series, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, subject to customary assumptions and exclusions, the holders of the outstanding debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred;

| • |  | in the case of covenant defeasance, we have delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that, subject to customary assumptions and exclusions, the holders of the outstanding debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred;

| • |  | no default or event of default has occurred and is continuing on the date of such deposit (other than a default or event of default resulting from the borrowing of funds to be applied to make such deposit and the grant of any lien securing such borrowings);

| • |  | such legal defeasance or covenant defeasance will not result in a breach or violation of, or constitute a default under any other material agreement or instrument (other than the indenture) to which we or any guarantor is a party or by which we or any guarantor is bound;

| • |  | we must deliver to the trustee an officers’ certificate stating that the deposit was not made by us with the intent of preferring the holders of the debt securities over the other creditors of ours or any guarantor or defeating, hindering, delaying or defrauding creditors of ours or any guarantor or others; and

| • |  | we must deliver to the trustee an officers’ certificate and an opinion of counsel (which opinion of counsel may be subject to customary assumptions and exclusions), each stating that all conditions precedent provided for or relating to the legal defeasance or the covenant defeasance, as the case may be, have been complied with.

Senior Debt Securities

The senior debt securities will be unsecured senior obligations and will rank equally with all other senior unsecured and unsubordinated debt. The senior debt securities will, however, be effectively subordinated in right of payment to all of our secured indebtedness to the extent of the value of the assets securing that indebtedness. Except as provided in the senior indenture or specified in any authorizing resolution or supplemental indenture relating to a series of senior debt securities to be issued, no senior indenture will limit the amount of additional indebtedness that may rank equally with the senior debt securities or the amount of indebtedness, secured or otherwise, that may be incurred or preferred shares that may be issued by any of our subsidiaries.

Subordinated Debt

Subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner set forth in the indenture, to all of our “senior indebtedness.” The indenture defines “senior indebtedness” as all obligations or indebtedness of, or guaranteed or assumed by, us for borrowed money whether or not represented by bonds, notes, debentures or other similar instruments, and amendments, renewals, extensions,

22

##### Table of Contents

modifications and refundings of any such indebtedness or obligation, in each case, whether outstanding on the date hereof or the date the debt securities are issued or created, incurred, or thereafter guaranteed or assumed. “Senior indebtedness” does not include any subordinated debt securities or any other obligations specifically designated as being subordinate in right of payment to senior indebtedness.

In general, the holders of all senior indebtedness are first entitled to receive payment of the full amount unpaid on senior indebtedness before the holders of any of the subordinated debt securities are entitled to receive a payment on account of the principal or interest on the indebtedness evidenced by the subordinated debt securities in certain events. Because the subordinated debt securities will be our unsecured obligations, our secured debt and other secured obligations will also be effectively senior to the subordinated debt securities to the extent of the value of the assets securing such debt or other obligations.

Corporate Existence

Subject to the terms of the indenture, we will do or cause to be done all things necessary to preserve and keep in full force and effect our corporate (and in the case of CDW LLC, limited liability company) existence, charter and statutory rights and franchises; provided, however, that we will not be required to preserve any right or franchise if we determine that the preservation thereof is no longer desirable in the conduct of our business.

Governing Law

The indentures and our debt securities will be governed by, and construed in accordance with, the law of the State of New York.

Guarantees

If the applicable prospectus supplement relating to a series of debt securities provides that those debt securities will have the benefit of a guarantee by CDW Corporation and/or any of its then existing or future domestic subsidiaries, then the debt securities will be fully and unconditionally guaranteed by such guarantors. Unless otherwise specified in the applicable prospectus supplement, we expect that the debt securities will be guaranteed by the guarantors under our existing indentures and our existing senior credit facilities. The guarantees will be general obligations of each guarantor. The guarantees will be joint and several obligations of the guarantors. If a series of debt securities is so guaranteed, the indenture or a supplemental indenture to the base indenture will be executed by each guarantor. The obligations of each guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance under applicable law. The terms of any guarantee and the conditions upon which any guarantor may be released from its obligations under that guarantee will be set forth in the applicable prospectus supplement.

DESCRIPTION OF SHARE PURCHASE CONTRACTS AND SHARE PURCHASE UNITS

We may issue share purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock and the number of shares of common stock may be fixed at the time the share purchase contracts are issued or may be determined by reference to a specific formula stated in the share purchase contracts.

The share purchase contracts may be issued separately or as part of units that we call “share purchase units.” Share purchase units consist of a share purchase contract and either our debt securities or debt obligations of third parties, including United States treasury securities, securing the holders’ obligations to purchase the common stock under the share purchase contracts.

The share purchase contracts may require us to make periodic payments to the holders of the share purchase units or vice versa, and these payments may be unsecured or refunded on some basis. The share purchase contracts may require holders to secure their obligations in a specified manner.

The applicable prospectus supplement will describe the terms of the share purchase contracts or share purchase units. The description in the prospectus supplement will only be a summary, and you should read the share purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the share purchase contracts or share purchase units. Material United States federal income tax considerations applicable to the share purchase units and the share purchase contracts will also be discussed in the applicable prospectus supplement.

Each share purchase contract or share purchase unit and any related agreement will be governed by, and construed in accordance with, the laws of the State of New York.

If we or any selling stockholders use underwriters or dealers in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including:

| • |  | privately negotiated transactions;

| • |  | at a fixed public offering price or prices, which may be changed;

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If underwriters are used in the sale of any securities, the securities may be offered either to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to certain conditions precedent. The underwriters will be obligated to purchase all of the securities if they purchase any of the securities.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or a post-effective amendment to this registration statement.

##### Table of Contents

If indicated in an applicable prospectus supplement, we and any selling stockholders may sell the securities through agents from time to time. The applicable prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions paid to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment. We and any selling stockholders may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us and any selling stockholders at the public offering price set forth in the applicable prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The delayed delivery contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the applicable prospectus supplement will set forth any commissions paid for solicitation of these delayed delivery contracts.

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us or any selling stockholders. Any remarketing firm will be identified and the terms of its agreements, if any, with us or any selling stockholders and its compensation will be described in the applicable prospectus supplement.

Agents, underwriters and other third parties described above may be entitled to indemnification by us or any selling stockholders against certain civil liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents, underwriters and such other third parties may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

Each series of securities will be a new issue of securities and may not have an established trading market, other than our common stock, which is listed on the Nasdaq Global Select Market. The securities other than the common stock may or may not be listed on a national securities exchange and no assurance can be given that there will be a secondary market for any such securities or liquidity in the secondary market if one develops. Any underwriters to whom securities are sold by us or any selling stockholders for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

Section 145 (“Section 145”) of the Delaware General Corporation Law, as the same exists or may hereafter be amended (the “DGCL”), provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to

II-1

##### Table of Contents

believe that his conduct was illegal. A Delaware corporation may indemnify any persons who are, were or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reasons of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, provided that no indemnification is permitted without judicial approval if the officer, director, employee or agent is adjudged to be liable to the corporation. Where an officer, director, employee or agent is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

Section 183.0106(2)(m) of the Wisconsin Limited Liability Company Act (“WLLCA”) permits a limited liability company to indemnify a member, manager, employee, officer or agent or any other person. Section 183.0403(2) of the WLLCA provides that a company shall indemnify or allow reasonable expenses to and pay liabilities of each member and, if management of the limited liability company is vested in one or more managers, of each manager, incurred with respect to a proceeding if that member or manager was a party to the proceeding in the capacity of a member or manager. However, the WLLCA does not permit a limited liability company to indemnify a member or manager for liabilities, or permit a member or manager to retain any allowance for such expenses, unless it is determined by or on behalf of the limited liability company that the liabilities or expenses did not result from the member’s or manager’s breach or failure to perform a duty to the limited liability company.

The operating agreement for CDW Technologies LLC provides for indemnification of all current and former managers and officers to the fullest extent of the WLLCA.

Item 17. Undertakings.

(a) Each of the undersigned registrants 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;

(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% 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; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, 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.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933, as amended (the “Securities Act”), shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-9

##### Table of Contents

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) Each of the undersigned registrants hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of such annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in 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.

(c) If the securities being registered are offered to existing security holders pursuant to warrants or subscription rights and any securities not taken by security holders are to be reoffered to the public, each undersigned registrant hereby undertakes to supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus or applicable prospectus supplement, a post-effective amendment will be filed to set forth the terms of such offering.

(d) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referred to in Item 15, or otherwise, each of the registrants has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by such 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, such 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 and will be governed by the final adjudication of such issue.
