The persons or entities listed thereon are hereinafter referred to collectively as the “Purchasers” and individually as a “Purchaser.”
THE PARTIES HEREBY AGREE AS FOLLOWS:
1. Purchase and Sale of Preferred Stock.
1.1 Authorization of the Shares. The Company will on or before the Closing (as defined below) authorize the sale and issuance pursuant to this Agreement of up to 5,000,000 shares (the “Shares”) of its Series E Preferred Stock (the “Series E Preferred”), having the rights, preferences and privileges as set forth in the Amended and Restated Articles of Incorporation attached hereto as EXHIBIT B (the “Restated Articles”).
1.2 Purchase and Sale of the Shares. Subject to the terms and conditions hereof and in reliance upon the representations, warranties and agreements contained herein, the Company will issue and sell to each Purchaser, severally and not jointly, and each Purchaser will purchase from the Company, severally and not jointly, at the Closing, the number of Shares set forth opposite the Purchaser’s name on the Schedule of Purchasers, at a purchase price of Four Dollars ($4.00) per Share. The Company shall be entitled to sell any unpurchased Shares to any Purchaser or to a person who is not a Purchaser and to amend the Schedule of Purchasers to include the information relating to such sales, and such purchasers shall be considered “Purchasers” and parties to this Agreement; provided that (i) such sales are made pursuant to this Agreement or an agreement identical to this one except for the Closing Date and exhibits, and (ii) such sales are completed within 120 days of the Initial Closing (as defined below). The Company’s agreement with each Purchaser is a separate agreement, and the sale of the Shares to each Purchaser is a separate sale.

Subject to Section 1.2 above, subsequent closings under this Agreement may be held from time to time after the Initial Closing at such time and place as the Company and the relevant Purchasers agree (“Subsequent Closings”). For the purposes of this Agreement, the term “Closing” and “Closing Date” unless otherwise indicated, refers to the closing or date of closing of the purchase and sale of the Shares with respect to a particular Purchaser or group of Purchasers, whether such closing occurs at the Initial Closing or at a Subsequent Closing.

(d) The Company is not aware that any of its employees is obligated under any agreement, or subject to any judgment, decree or order of any court or administrative agency, that would materially interfere with his or her ability to fully and freely perform their duties to the Company or that would conflict with the Company’s business. To the Company’s knowledge, neither the filing of the Restated Articles nor the execution and delivery of this Agreement or the Investor Rights Agreement, nor the carrying on of the Company’s business by the employees of the Company, will conflict with or result in a material breach of the terms, conditions, or provisions of, or constitute a default under, any agreement under which any such employee is now obligated.

(e) Except as described in Schedule 2.10, (i) the Company is not obligated, or under any liability whatsoever to make any payments by way of royalties, fees or otherwise, to any owner or licensor of, or other claimant to, any Company Intellectual Property, and (ii) the Company is not a party to any agreement concerning the Company Intellectual Property or any other Intellectual Property Right used or to be used by the Company in its business as conducted. No founder, director, officer or employee of the Company, or, to the Company’s knowledge, no shareholder of the Company has any interest in the Company Intellectual Property.
(f) Except with respect to any rights granted under the agreements described in Schedule 2.10, the Company owns exclusively all rights arising from or associated with the research and development efforts of the Company, its founders, employees and independent contractors relating to the Company’s business as now conducted, and all such rights form part of the Company Intellectual Property. The Company has secured valid written assignments from all employees and independent contractors who contributed to the creation or development of any of the Company Intellectual Property of the rights to such contributions that the Company does not already own by operation of law. The Company has not received notice of any claim being asserted by any current or former employee, independent contractor or other third party to the ownership, of or right to use, any of the Company Intellectual Property, or challenging or questioning the validity of any of the Company Intellectual Property, and the Company is not aware of any basis for any such claim.
(g) The Company has taken reasonable steps to protect and preserve the confidentiality of all material trade secrets included in Company Intellectual Property not otherwise protected by patents or copyright (“Confidential Information”). All disclosure of Confidential Information to a third party has been pursuant to the terms of a written confidentiality or non-disclosure agreement between the Company and such third party.
(h) The Company hereby represents and warrants that the data, written and oral reports and other representations and information that the Company provided to its investors (or their counsel) pertaining to the Company Intellectual Property, when taken as a whole, were truthful and, to the Company’s knowledge, accurate in all material respects, and there was no omission therefrom which made such information misleading, or incomplete in any material way.

The execution, delivery and performance of and compliance with this Agreement and the Investor Rights Agreement, and the issuance and sale of the Shares, will not result in any such violation, be in conflict with or constitute, with or without the passage of time or giving of notice, a default under any such provision, license, indenture, instrument, mortgage, deed of trust, loan, contract, commitment, judgment, decree, order or obligation; or require any consent or waiver under any such provision, license, indenture, instrument, mortgage, deed of trust, loan, contract, commitment, judgment, decree, order or obligation (other than any consents or waivers that have been obtained); or result in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of the Company pursuant to any such provision, license, indenture, instrument, mortgage, deed of trust, loan, contract, commitment, judgment, decree, order or obligation.

The Company has paid all taxes and other assessments due. The Company has not elected pursuant to the Code, to be treated as a Subchapter S corporation or a collapsible corporation pursuant to Section 1362(a) or Section 341(f) of the Code, nor has it made any other elections pursuant to the Code (other than elections that relate solely to methods of accounting, depreciation or amortization) that would have a material effect on the business, properties or condition (financial or otherwise) of the Company. None of the Company’s tax returns have ever been audited by any governmental authorities.

2.24 Disclosure. The Company has fully provided each Purchaser with all the information which such Purchaser has requested in connection with the purchase of the Shares hereunder, as well as all information which the Company in its judgment believes is reasonably necessary to enable such Purchaser to make a decision as to whether to invest in the Company. Neither this Agreement with the Exhibits hereto, nor any other statements, certificates or documents made or delivered in connection herewith or therewith, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements herein or therein not misleading in light of the circumstances under which they were made. The financial projections made available to the Purchasers (the “Projections”) were prepared in good faith and based upon assumptions that the Company believes are reasonable, and represent the Company’s good faith

-10-

estimate of its future plans and results; provided however that the Company does not represent or warrant that it will achieve any of the Projections.
2.25 Offering. Subject in part to the truth and accuracy of each Purchaser’s representations set forth in this Agreement, the offer, sale and issuance of the Shares as contemplated by this Agreement is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), and from the registration or qualification requirements of applicable state securities laws or blue sky laws, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemption.

3.2 Investment. Such Purchaser is acquiring the Shares, and the Conversion Shares, for investment for such Purchaser’s own account and not with the view to, or for resale in connection with, any distribution thereof. Such Purchaser understands that the Shares, and the Conversion Shares have not been registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent as expressed herein. Such Purchaser further represents that it does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participation to any third person with respect to any of the Shares, or the Conversion Shares, other than a transfer not involving a change of beneficial ownership. Such Purchaser understands and acknowledges that the offering of the Shares pursuant to this Agreement will not be registered under the Securities Act on the ground that the sale provided for in this Agreement is exempt from the registration requirements of the Securities Act.
3.3 Rule 144. Such Purchaser acknowledges that the Shares and the Conversion Shares must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available. Such Purchaser is aware of the provisions of Rule 144 promulgated under the Securities Act which permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions. Such Purchaser covenants that, in the absence of an effective registration statement covering the stock in question, such Purchaser will sell, transfer, or otherwise dispose of the Shares or the Conversion Shares only in a manner consistent with applicable securities laws and such Purchaser’s representations and covenants set forth in this Section 3. In connection therewith, such Purchaser acknowledges that the Company

3.5 No Public Market. Such Purchaser understands that no public market now exists for any of the securities issued by the Company, and that the Company has made no assurances that a public market will ever exist for the Shares or the Conversion Shares.
3.6 Access to Data. Such Purchaser has received and reviewed information about the Company and has had an opportunity to discuss the Company’s business, management and financial affairs with its management and to review the Company’s facilities. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 of this Agreement or the right of the Purchasers to rely thereon.
3.7 Authorization. This Agreement when executed and delivered by such Purchaser will constitute a valid and legally binding obligation of the Purchaser, enforceable against the Purchaser in accordance with its terms, subject to: (i) judicial principles respecting election of remedies or limiting the availability of specific performance, injunctive relief, and other equitable remedies; (ii) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect generally relating to or affecting creditors’ rights; and (iii) limitations on the enforceability of the indemnification provisions of the Investor Rights Agreement.
3.8 Accredited Investor. Such Purchaser acknowledges that it is an “accredited investor” as defined in Rule 501 of Regulation D as promulgated by the Securities and Exchange Commission under the Securities Act and shall submit to the Company such further assurances of such status as may be reasonably requested by the Company. The principal address of such Purchaser is as set forth on the Schedule of Purchasers.
3.9 Public Solicitation. Purchaser knows of no public solicitation or advertisement of an offer in connection with the proposed issuance and sale of the Shares.

3.11 Purchaser Counsel. Purchaser acknowledges that it has had the opportunity to review this Agreement, the exhibits and the schedules attached hereto and the transactions contemplated by this Agreement with Purchaser’s own legal counsel. Each Purchaser is relying

solely on such counsel and not on any statements or representations of the Company or any of its agents for legal advice with respect to this investment or the transactions contemplated by this Agreement.

3.13 Non-United States Persons. If Purchaser is not a United States person, such Purchaser hereby represents that such Purchaser is satisfied as to the full observance of the laws of such Purchaser’s jurisdiction in connection with any invitation to subscribe for the Shares and the Conversion Shares or any use of this Agreement, the Investor Rights Agreement and the Voting Agreement, including (i) the legal requirements within such Purchaser’s jurisdiction for the purchase of Shares and the Conversion Shares, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of such securities.

(i) If the securities are then traded on a national securities exchange or the Nasdaq Stock Market System (or a similar national quotation system), then the value of the securities shall be deemed to be to the average of the closing prices of the securities on such exchange or system over the ten (10) trading day period ending five (5) trading days prior to the distribution;

-6-

#####

(ii) if the securities are actively traded over-the-counter, then the value of the securities shall be deemed to be the average of the closing bid prices of the securities over the ten (10) trading day period ending five (5) trading days prior to the distribution; or
(iii) if there is no active public market for the securities, then the value of the securities shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors which determination shall include consideration of the illiquidity of the securities.
In the event of a merger or other acquisition of the Corporation by another entity, the distribution date shall be deemed to the date such transaction closes.
For the purposes of this Section 3(i), “trading day” shall mean any day on which the exchange or system on which the securities to be distributed are traded is open, and “closing prices” or “closing bid prices” shall be deemed to be: (i) for securities traded primarily on the New York Stock Exchange, the American Stock Exchange or Nasdaq, the last reported trade price or sale price, as the case may be, at 4:00 p.m., New York time, on that day and (ii) for securities listed or traded on other exchanges, markets and systems, the market price as of the end of the “regular hours” trading period that is generally accepted as such for such exchange, market or system. If, after the date hereof, the benchmark times generally accepted in the securities industry for determining the market price of a stock as of a given trading day shall change from those set forth above, the fair market value shall be determined as of such other generally accepted benchmark times.
4. Conversion. The holders of the Preferred Stock shall have conversion rights as follows (the “Conversion Rights”):
(a) Right to Convert. Subject to Section 4(c), each share of Preferred Stock shall be convertible, at the option of the holder thereof, at any time after the date of issuance of such share at the office of the Corporation or any transfer agent for the Preferred Stock, into that number of fully-paid, nonassessable shares of Common Stock determined by dividing the Original Issue Price for the relevant series by the Conversion Price for such series. (The number of shares of Common Stock into which each share of Preferred Stock of a series may be converted is hereinafter referred to as the “Conversion Rate” for each such series.) Upon any decrease or increase in the Conversion Price for any series of Preferred Stock, as described in this Section 4, the Conversion Rate for such series shall be appropriately increased or decreased.
(b) Automatic Conversion. Each share of Preferred Stock shall automatically be converted into fully-paid, non-assessable shares of Common Stock at the then effective Conversion Rate for such share (i) immediately prior to the closing of a firm commitment underwritten initial public offering on Form S-1 (or successor form) filed under the Securities Act of 1933, as amended (the “Securities Act”), covering the offer and sale of the Corporation’s Common Stock, provided that the offering price per share is not less than $5.69 (as adjusted for subdivisions and combinations of the Common Stock and changes in the Common Stock as set forth in Sections 4(e) and 4(g)) and the aggregate gross proceeds to the Corporation are not less than $25,000,000, or (ii) upon the receipt by the Corporation of a written consent or request for such conversion from the holders of two-thirds of the shares of Preferred Stock then outstanding, or, if later, the effective date for

-7-

#####

conversion specified in such requests (each of the events referred to in (i) and (ii) being hereinafter referred to as an “Automatic Conversion Event”).
(c) Mechanics of Conversion. No fractional shares of Common Stock shall be issued upon conversion of Preferred Stock. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then fair market value of a share of Common Stock as determined by the Board of Directors. For such purpose, all shares of Preferred Stock held by each holder of Preferred Stock shall be aggregated, and any resulting fractional share of Common Stock shall be paid in cash. Before any holder of Preferred Stock shall be entitled to convert the same into full shares of Common Stock, and to receive certificates therefor, he shall either surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Preferred Stock, or notify the Corporation or its transfer agent that such certificate or certificates have been lost, stolen or destroyed and execute an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificate or certificates, and shall give written notice to the Corporation at such office that he elects to convert the same; provided, however, that on the date of an Automatic Conversion Event, the outstanding shares of Preferred Stock shall be converted automatically without any further action by the holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent; provided further, however, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such Automatic Conversion Event unless either the certificates evidencing such shares of Preferred Stock are delivered to the Corporation or its transfer agent as provided above, or the holder notifies the Corporation or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates. On the date of the occurrence of an Automatic Conversion Event, each holder of record of shares of Preferred Stock shall be deemed to be the holder of record of the Common Stock issuable upon such conversion, notwithstanding that the certificates representing such shares of Preferred Stock shall not have been surrendered at the office of the Corporation, that notice from the Corporation shall not have been received by any holder of record of shares of Preferred Stock, or that the certificates evidencing such shares of Common Stock shall not then be actually delivered to such holder.
The Corporation shall, as soon as practicable after such delivery, or after such agreement and indemnification, issue and deliver at such office to such holder of Preferred Stock, a certificate or certificates for the number of shares of Common Stock to which he shall be entitled as aforesaid and a check payable to the holder in the amount of any cash amounts payable as the result of a conversion into fractional shares of Common Stock, plus any declared and unpaid dividends on the converted Preferred Stock. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date; provided, however, that if the conversion is in connection with an underwritten offer of securities registered pursuant to the Securities Act the conversion may, at the option of any holder tendering Preferred Stock for conversion, be conditioned upon the closing of the sale of securities pursuant to such offering, in which event the person(s) entitled to receive the

-8-

#####

Common Stock issuable upon such conversion of the Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the closing of the sale of such securities.
(d) Adjustments to Conversion Price for Diluting Issues.
(i) Special Definition. For purposes of this Section 4(d), “Additional Shares of Common” shall mean all shares of Common Stock issued (or, pursuant to Section 4(d)(iii), deemed to be issued) by the Corporation after the filing of these Articles of Incorporation, other than:
(1) [omitted];
(2) shares of Common Stock issued or issuable to officers, directors and employees of, or consultants and other service providers to, the Corporation pursuant to stock grants, option plans, purchase plans or other employee stock incentive programs or arrangements approved by the Board of Directors or upon exercise of options or warrants granted to such parties pursuant to any such plan, program or arrangement;
(3) shares of Common Stock issued upon the exercise or conversion of Options or Convertible Securities outstanding as of the date of the filing of these Articles of Incorporation;
(4) shares of Common Stock issued or issuable as a dividend or distribution on Preferred Stock or pursuant to any event for which adjustment is made pursuant to Section 4(e), 4(f) or 4(g) hereof;
(5) shares of Common Stock issued in a registered public offering under the Securities Act pursuant to which all outstanding shares of Preferred Stock are automatically converted into Common Stock pursuant to an Automatic Conversion Event;
(6) shares of Common Stock issued or issuable pursuant to the acquisition of another corporation by the Corporation by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, provided, that such issuances are unanimously approved by the Board of Directors;
(7) shares of Common Stock issued or issuable to banks, equipment lessors or other financial institutions pursuant to a commercial leasing or debt financing transaction approved by the Board of Directors;
(8) shares of Common Stock issued or issuable in connection with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements, or strategic partnerships or relationships, if the issuance is approved by the Board of Directors; and
(9) shares of Common Stock issued or issuable upon conversion of up to $18 million in aggregate principal amount (plus interest) of convertible promissory notes originally issued or issuable to Biomedical Sciences Investment Fund Pte Ltd. or its affiliates (“BMSIF”) and upon conversion of up to $3 million in aggregate principal amount (plus interest) of convertible promissory notes originally issued or issuable to Invus, L.P. or its affiliates, provided

-9-

#####

that with respect to any shares of Common Stock issued or issuable upon conversion of convertible promissory notes issued or issuable to BMSIF after the filing of these Articles of Incorporation with an aggregate principal amount in excess of $3.0 million, such shares of Common Stock shall only be excluded from the definition of Additional Shares of Common pursuant to this section if and to the extent the applicable conversion price for such shares equals or exceeds $3.60 (as adjusted for stock splits, subdivisions, combinations or stock dividends).
(ii) No Adjustment of Conversion Price. No adjustment in the Conversion Price of a particular series of Preferred Stock shall be made in respect of the issuance of Additional Shares of Common unless the consideration per share (as determined pursuant to Section 4(d)(vii)) for an Additional Share of Common issued or deemed to be issued by the Corporation is less than the Conversion Price in effect on the date of, and immediately prior to such issue, for such series of Preferred Stock.
(iii) Deemed Issue of Additional Shares of Common. In the event the Corporation at any time or from time to time after the date of the filing of these Articles of Incorporation shall issue any Options or Convertible Securities or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number) of Common Stock issuable upon the exercise of such Options or, in the case of Convertible Securities, the conversion or exchange of such Convertible Securities or, in the case of Options for Convertible Securities, the exercise of such Options and the conversion or exchange of the underlying securities, shall be deemed to have been issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date, provided that in any such case in which shares are deemed to be issued:
(1) no further adjustment in the Conversion Price of the Preferred Stock shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock in connection with the exercise of such Options or conversion or exchange of such Convertible Securities pursuant to the terms of such Options or Convertible Securities;
(2) if no adjustment in the Conversion Price of the Preferred Stock was made upon the original issue of (or upon the occurrence of a record date with respect to) such Options or Convertible Securities and such Options or Convertible Securities are revised to provide, or by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to the Corporation, or any increase or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, then such Options or Convertible Securities as so revised (and the Additional Shares of Common subject thereto) shall be deemed to have been issued effective upon such increase or decrease becoming effective;
(3) if such Options or Convertible Securities are revised to provide, or by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to the Corporation, or any increase or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Conversion Price of the Preferred Stock computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon,

-10-

#####

shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;
(4) no readjustment pursuant to clause (3) above shall have the effect of increasing the Conversion Price of the Preferred Stock to an amount which exceeds the lower of (i) the Conversion Price of the Preferred Stock on the original adjustment date, or (ii) the Conversion Price of the Preferred Stock that would have resulted from any issuance of Additional Shares of Common between the original adjustment date and such readjustment date;
(5) upon the expiration of any such Options or any rights of conversion or exchange under such Convertible Securities which shall not have been exercised, the Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto) and any subsequent adjustments based thereon shall, upon such expiration, be recomputed as if:
(A) in the case of Convertible Securities or Options for Common Stock, the only Additional Shares of Common issued were the shares of Common Stock, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Corporation for the issue of such exercised Options plus the consideration actually received by the Corporation upon such exercise or for the issue of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Corporation upon such conversion or exchange, and
(B) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issue of such Options, and the consideration received by the Corporation for the Additional Shares of Common deemed to have been then issued was the consideration actually received by the Corporation for the issue of such exercised Options, plus the consideration deemed to have been received by the Corporation (determined pursuant to Section 4(d)(vii)) upon the issue of the Convertible Securities with respect to which such Options were actually exercised; and
(6) if such record date shall have been fixed and such Options or Convertible Securities are not issued on the date fixed therefor, the adjustment previously made in the Conversion Price which became effective on such record date shall be canceled as of the close of business on such record date, and thereafter the Conversion Price shall be adjusted pursuant to this Section 4(d)(iii) as of the actual date of their issuance.
(iv) Adjustment of Conversion Price of Series E Preferred Stock Upon Issuance of Additional Shares of Common.
(1) For so long as the Conversion Price of the Series E Preferred Stock is greater than $2.58 (as adjusted for subdivisions and combinations of the Common Stock and changes in the Common Stock as set forth in Sections 4(e) and 4(g)) (the “Series D/E Ratchet Amount”), in the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) for a consideration

-11-

#####

per share less than the applicable Conversion Price of the Series E Preferred Stock in effect on the date of and immediately prior to such issue, but for a consideration per share equal to or greater than the Series D/E Ratchet Amount, then the Conversion Price of the Series E Preferred Stock shall be reduced concurrently with such issue to a price (calculated to the nearest cent) equal to the per share price of the Additional Shares of Common.
(2) In the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) without consideration or for a consideration per share less than the Series D/E Ratchet Amount, then the Conversion Price of the Series E Preferred Stock immediately prior to such issue shall be deemed to be equal to the Series D/E Ratchet Amount (the “Series E Adjusted Conversion Price”), and such Series E Adjusted Conversion Price shall be further reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Series E Adjusted Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares of Common Stock which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common so issued would purchase at such Adjusted Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common so issued. For the purposes of this Section 4(d)(iv)(2), all shares of Common Stock issuable upon exercise of outstanding Options or the conversion of outstanding Convertible Securities and shares of Preferred Stock, and all Additional Shares of Common deemed issued pursuant to Section 4(d)(iii) hereof, shall be deemed to be outstanding. Section 4(d)(iv)(3) shall govern adjustments to the Conversion Price of the Series E Preferred Stock after the first adjustment to the Conversion Price of the Series E Preferred Stock pursuant to this Section 4(d)(iv)(2).
(3) After any adjustment to the Conversion Price of the Series E Preferred Stock pursuant to Section 4(d)(iv)(2), in the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) without consideration or for a consideration per share less than Conversion Price of the Series E Preferred Stock in effect on the date of and immediately prior to such issue, then, the Conversion Price of the Series E Preferred Stock shall be reduced concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares of Common Stock which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common so issued would purchase at such Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common so issued. For the purposes of this Section 4(d)(iv)(3), all shares of Common Stock issuable upon exercise of outstanding Options or the conversion of outstanding Convertible Securities and shares of Preferred Stock, and all Additional Shares of Common deemed issued pursuant to Section 4(d)(iii) hereof, shall be deemed to be outstanding.

-12-

#####

(v) Adjustment of Conversion Price of Series D Preferred Stock Upon Issuance of Additional Shares of Common.
(1) For so long as the Conversion Price of the Series D Preferred Stock is greater than the Series D/E Ratchet Amount, in the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) for a consideration per share less than the applicable Conversion Price of the Series D Preferred Stock in effect on the date of and immediately prior to such issue, but for a consideration per share equal to or greater than the Series D/E Ratchet Amount, then the Conversion Price of the Series D Preferred Stock shall be reduced concurrently with such issue to a price (calculated to the nearest cent) equal to the per share price of the Additional Shares of Common.
(2) In the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) without consideration or for a consideration per share less than the Series D/E Ratchet Amount, then the Conversion Price of the Series D Preferred Stock immediately prior to such issue shall be deemed to be equal to the Series D/E Ratchet Amount (the “Series D Adjusted Conversion Price”), and such Series D Adjusted Conversion Price shall be further reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Series D Adjusted Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares of Common Stock which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common so issued would purchase at such Series D Adjusted Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common so issued. For the purposes of this Section 4(d)(v)(2), all shares of Common Stock issuable upon exercise of outstanding Options or the conversion of outstanding Convertible Securities and shares of Preferred Stock, and all Additional Shares of Common deemed issued pursuant to Section 4(d)(iii) hereof, shall be deemed to be outstanding. Section 4(d)(v)(3) shall govern adjustments to the Conversion Price of the Series D Preferred Stock after the first adjustment to the Conversion Price of the Series D Preferred Stock pursuant to this Section 4(d)(v)(2).
(3) After any adjustment to the Conversion Price of the Series D Preferred Stock pursuant to Section 4(d)(v)(2), in the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) without consideration or for a consideration per share less than Conversion Price of the Series D Preferred Stock in effect on the date of and immediately prior to such issue, then, the Conversion Price of the Series D Preferred Stock shall be reduced concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares of Common Stock which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common so issued would purchase at such Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common so issued. For the purposes of this Section 4(d)(v)(3), all shares of Common Stock issuable upon exercise of outstanding Options or the conversion of outstanding Convertible

-13-

#####

Securities and shares of Preferred Stock, and all Additional Shares of Common deemed issued pursuant to Section 4(d)(iii) hereof, shall be deemed to be outstanding.
(vi) Adjustment of Conversion Price of Series A, B and C Preferred Stock. In the event this Corporation shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 4(d)(iii)) without consideration or for a consideration per share less than the applicable Conversion Price of the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock in effect on the date of and immediately prior to such issue, then, the Conversion Price of the Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock (if affected) shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of shares of Common Stock which the aggregate consideration received by the Corporation for the total number of Additional Shares of Common so issued would purchase at such Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common so issued. For the purposes of this Section 4(d)(vi), all shares of Common Stock issuable upon exercise of outstanding Options or the conversion of outstanding Convertible Securities and shares of Preferred Stock, and all Additional Shares of Common deemed issued pursuant to Section 4(d)(iii) hereof, shall be deemed to be outstanding.
(vii) Determination of Consideration. For purposes of this Section 4(d), the consideration received by the Corporation for the issue (or deemed issue) of any Additional Shares of Common shall be computed as follows:
(1) Cash and Property. Such consideration shall:
(A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation before deducting reasonable discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with such issue (or deemed issue);
(B) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and
(C) in the event Additional Shares of Common are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (A) and (B) above, as reasonably determined in good faith by the Board of Directors.
(2) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common deemed to have been issued pursuant to Section 4(d)(iii) shall be determined by dividing
(X) the total amount, if any, received or receivable by the Corporation as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating

-14-

#####

thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities by
(Y) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.
(e) Adjustments for Subdivisions or Combinations of Common Stock. In the event the outstanding shares of Common Stock shall be subdivided (by stock split, by payment of a stock dividend or otherwise), into a greater number of shares of Common Stock, the Conversion Price of each series of Preferred Stock in effect immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In the event the outstanding shares of Common Stock shall be combined (by reclassification or otherwise) into a lesser number of shares of Common Stock, the Conversion Prices in effect immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately increased.
(f) Adjustments for Subdivisions or Combinations of Preferred Stock. In the event the outstanding shares of Preferred Stock or a series of Preferred Stock shall be subdivided (by stock split, by payment of a stock dividend or otherwise), into a greater number of shares of Preferred Stock, the Dividend Rate, Original Issue Price and Liquidation Preference of the affected series of Preferred Stock in effect immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately decreased. In the event the outstanding shares of Preferred Stock or a series of Preferred Stock shall be combined (by reclassification or otherwise) into a lesser number of shares of Preferred Stock, the Dividend Rate, Original Issue Price and Liquidation Preference of the affected series of Preferred Stock in effect immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately increased.
(g) Adjustments for Reclassification, Exchange and Substitution. Subject to Section 3 above (“Liquidation Rights”), if the Common Stock issuable upon conversion of the Preferred Stock shall be changed into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares provided for above), then, in any such event, in lieu of the number of shares of Common Stock which the holders would otherwise have been entitled to receive, each holder of such Preferred Stock shall have the right thereafter to convert such shares of Preferred Stock into a number of shares of such other class or classes of stock which a holder of the number of shares of Common Stock deliverable upon conversion of such series of Preferred Stock immediately before that change would have been entitled to receive in such reorganization or reclassification, all subject to further adjustment as provided herein with respect to such other shares.
(h) No Impairment. The Corporation will not through any reorganization, transfer of assets, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek

-15-

#####

to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of Preferred Stock against impairment. Notwithstanding the foregoing, nothing in this Section 4(h) shall prohibit the Corporation from amending its Articles of Incorporation with the requisite consent of its shareholders and the board of directors.
(i) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 4, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of Preferred Stock.
(j) Notices of Record Date. In the event that this Corporation shall propose at any time:
(i) to declare any dividend or distribution upon its Common Stock, whether in cash, property, stock or other securities, whether or not a regular cash dividend and whether or not out of earnings or earned surplus;
(ii) to effect any reclassification or recapitalization of its Common Stock outstanding involving a change in the Common Stock; or
(iii) to voluntarily liquidate or dissolve or to enter into any transaction deemed to be a liquidation, dissolution or winding up of the corporation pursuant to Section 3(f);
then, in connection with each such event, this Corporation shall send to the holders of the Preferred Stock at least 14 days’ prior written notice of the date on which a record shall be taken for such dividend or distribution (and specifying the date on which the holders of Common Stock shall be entitled thereto) or for determining rights to vote in respect of the matters referred to in (ii) and (iii) above.
Each such written notice shall be given by first class mail, postage prepaid, addressed to the holders of Preferred Stock at the address for each such holder as shown on the books of this Corporation.
The right of the holders of the Preferred Stock to notice hereunder may be waived by the holders of more than two-thirds (2/3) of the outstanding shares of the Preferred Stock voting together as a single class.
(k) Reservation of Stock Issuable Upon Conversion. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock solely

-16-

#####

for the purpose of effecting the conversion of the shares of the Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all then outstanding shares of the Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Preferred Stock, the Corporation will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose.
(l) Waiver of Adjustment of Conversion Price. Notwithstanding anything herein to the contrary, any downward adjustment of the Conversion Price of any series of Preferred Stock may be waived by the consent or vote of the holders of more than two-thirds (2/3) of the outstanding shares of such series. Any such waiver shall bind all future holders of shares of such series of Preferred Stock.
5. Voting.
(a) Restricted Class Voting. Except as otherwise expressly provided herein or as required by law, the holders of Preferred Stock and the holders of Common Stock shall vote together and not as separate classes.
(b) No Series Voting. Other than as provided herein or required by law, there shall be no series voting.
(c) Preferred Stock. Each holder of Preferred Stock shall be entitled to the number of votes equal to the number of shares of Common Stock into which the shares of Preferred Stock held by such holder could be converted as of the record date. The holders of shares of the Preferred Stock shall be entitled to vote on all matters on which the Common Stock shall be entitled to vote. Holders of Preferred Stock shall be entitled to notice of any shareholders’ meeting in accordance with the Bylaws of the Corporation. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula (after aggregating all shares into which shares of Preferred Stock held by each holder could be converted), shall be disregarded.
(d) Common Stock. Each holder of shares of Common Stock shall be entitled to one vote for each share thereof held.
(e) Election of Directors. So long as at least 2,000,000 shares of Series D Preferred Stock (as adjusted for stock splits, subdivisions, combinations or stock dividends with respect to such shares) remain outstanding, the holders of the Series D Preferred Stock, voting as a separate class, shall be entitled to elect two (2) members of the Corporation’s Board of Directors at each meeting or pursuant to each consent of the Corporation’s shareholders for the election of directors. So long as at least 2,000,000 shares of Series C Preferred Stock (as adjusted for stock splits, subdivisions, combinations or stock dividends with respect to such shares) remain outstanding, the holders of Series C Preferred Stock, voting as a separate class, shall be entitled to elect three (3) members of the Corporation’s Board of Directors at each meeting or pursuant to each consent of the Corporation’s shareholders for the election of directors. Any additional members of the Corporation’s Board of Directors shall be elected by the holders of Common Stock, Series A

-17-

#####

Preferred Stock, Series B Preferred Stock, and Series E Preferred Stock, voting together as a single class.
6. Amendments and Changes Requiring Approval of Preferred Stock. As long as any of the Preferred Stock shall be issued and outstanding, the Corporation shall not, without first obtaining the approval (by vote or written consent as provided by law) of the holders of at least two-thirds (2/3) of the outstanding shares of the Preferred Stock voting together as a single class:
(a) amend, alter or repeal any provision of the Articles of Incorporation or By-laws of the Corporation if such action would adversely alter the rights, preferences, privileges or powers of, or restrictions provided for the benefit of the Preferred Stock or any series thereof;
(b) enter into any transaction or series of related transactions deemed to be a liquidation, dissolution or winding up of the Corporation pursuant to Section 3(f) above;
(c) voluntarily liquidate or dissolve;
(d) declare or pay any distribution (as defined in Section 2(d) except for distributions upon a liquidation or dissolution) with respect to the Common Stock of the Corporation;

In connection with these transactions, the Company borrowed $13,000,000 under the loan and security agreement and issued a warrant to Lighthouse to purchase 371,428 shares of the Company’s Series D Preferred Stock. As of September 30, 2007, the Company owed approximately $9,601,037 under the notes.
The Company is a party to a License Agreement between the Company and the California Institute of Technology (“Caltech”) dated May 1, 2000, which was amended and restated in June 2002 effective as of May 1, 2002, further amended in June 2003, with a restatement date of May 1, 2004, as further amended March 29, 2007 (collectively, the “Caltech License Agreement”). Pursuant to the Caltech License Agreement, the Company was obligated on an annual basis to issue to Caltech 50,000 shares of the Company’s Common Stock on each occasion that the Company determined to add patent rights to the license.
The Company and Biomedical Sciences Investment Fund Pte Ltd. (“BMSIF”) are parties to a Convertible Note Purchase Agreement dated as of December 18, 2003, as amended by Amendment No. 1 to Convertible Note Purchase Agreement dated December 17, 2004 and as further amended by a letter agreement dated June 30, 2005 (collectively, the “CNPA”). Pursuant to the CNPA, the Company issued a Convertible Promissory Note, as amended by Amendment to Convertible Promissory Note dated December 17, 2004, and as further amended by Amendment No. 2 to Convertible Promissory Note dated June 30, 2005 (collectively, the “Note”) to BMSIF in exchange for $2,000,000. In December 2005, upon the successful completion of certain specified milestones by the Company, the principal amount of and the accrued interest under the Note were converted into 832,635 shares of Series D Preferred Stock at a conversion price per share of $2.80.
In addition, as a result of the Company’s achieving of such specified milestones, the Company has required BMSIF to purchase an additional convertible promissory note (the “Supplemental Note”) in the aggregate principal amount of $3,000,000 on June 20, 2006.
The principal amount of and interest on the Supplemental Note was convertible into shares of Series D Preferred Stock of the Company at a conversion price of $2.80 per share (subject to adjustment) upon the earlier of an initial public offering in connection with which the Company’s

#####

Preferred Stock has converted into Common Stock or the satisfaction of certain specified milestones. In addition, BMSIF may electively convert the Supplemental Note into shares of Series D Preferred Stock at any time. The principal amount and interest under the Supplemental Note could not be prepaid except under limited circumstances. In July, 2007 upon completion of certain specified milestones by the Company, the principal amount of and the accrued interest under the Supplemental Note were converted into 1,157,142 shares of Series D Preferred Stock at a conversion price per share of $2.80.
The Company and Invus, L.P. are parties to a Convertible Note Agreement dated December 18, 2003, as amended by Amendment No. 1 to Convertible Note Agreement executed in November 2005 (the “CNA”). The CNA provides that in the event the Company issues to BMSIF Supplemental Notes in the aggregate principal amount of $3,000,000 upon the happening of certain events, Invus has the right to purchase a convertible promissory note in the principal amount of $3,000,000 (the “Invus Note”) from the Company. Recently, Invus, L.P. and the Company decided not to issue the Invus Note.
The Company and BMSIF entered into a Convertible Note Purchase Agreement, dated as of August 7, 2006, as amended by that certain Letter Agreement dated November 15, 2006 and as further amended by that certain Letter Agreement dated January 31, 2007 (as amended, the “2006 CNPA”). The 2006 CNPA permits the Company to borrow up to $15 million in three $5 million tranches, subject to availability based on the achievement of specified milestones. The Company has sold and issued to BMSIF all three convertible promissory notes, each in the principal amount of $5 million. The initial two convertible promissory notes converted into 1,460,730 and 1,493,607 shares of Series E Preferred Stock on March 31, 2007. Upon conversion of the second convertible promissory note, BMSIF purchased the third (and final) convertible promissory note in the principal amount of $5 million.
In March 2003, the Company entered into (i) a Master Closing Agreement (the “Master Closing Agreement”) with Oculus Pharmaceuticals, Inc. (“Oculus”) and the University of Alabama Research Foundation (“UABRF”); (ii) a License Agreement with UABRF; and (iii) a Sponsored Research Agreement with UABRF. The Company is obligated to issue up to $2,100,000 of additional shares of its stock to UABRF in connection with the satisfaction of certain milestones. If the Company is a private Company at the time a milestone is achieved, upon achievement of a milestone, the Company is to issue shares of the series of Preferred Stock that was issued in the Company’s most recent financing and the shares are to be valued at the price the shares were sold in such financing. If the Company is a public company at the time a milestone is achieved, upon achievement of a milestone, the Company is to issue shares of Common stock valued at the average closing price of the Company’s Common Stock over the five trading days preceding the achievement of the milestone. In February 2005, UABRF sent a letter to the Company requesting issuance of the shares in relation to the milestones. The Company replied in writing that the milestones had not been satisfied and that it had no obligation to issue the shares at that time. The Company achieved a milestone in 2006 and as a result issued $600,000 worth of shares of its Series D Preferred Stock to UABRF and other designated parties. Following the satisfaction of the milestone, the parties have been negotiating the Company’s continuing obligations, if any, under the agreements identified above, which may include an obligation on the part of the Company to issue additional shares of its stock to UABRF.
The Company is party to an offer letter with Richard DeLateur, the Company’s Chief Financial Officer, which provides that in the event of a Change of Control (as defined in the offer letter) 50% of the shares subject to the option granted to Mr. DeLateur in connection with his acceptance of

#####

employment with the Company that are unvested at the time of such Change of Control shall become immediately vested.
The Company has approved an issuance of 6,000 shares of the Company’s Common Stock to Stanford University. Such issuance has not been completed.
See Section 2.10(f) regarding Dr. Stephen R. Quake.
2.7 Government Consents
The Company makes no representation or warranty with respect to any consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with any foreign governmental entity and has assumed for purposes of the Agreement that none of the foregoing is required.
2.8 Litigation
See Section 2.10(a).
The Company has received a letter from a supplier of certain materials used in the Company’s Topaz and certain other products requesting that the Company cease and desist using a lid with the materials or obtain a license from the supplier for using the design of the lid. Upon investigation, the Company determined that it had developed the lid design independently from the supplier and also began developing alternates to the materials, which are currently approved for manufacturing. The Company wrote a letter explaining these opinions to the supplier and the parties have been in negotiations regarding this matter resulting in the supplier providing a proposed settlement agreement with a $55,000 buy-out option for the Company and the Company replied with a revised draft settlement agreement. The Company is currently waiting for the supplier to comment on the revised draft settlement agreement.
2.9 Employees
William Smith, the Company’s general counsel, is currently working for the Company and also remains a partner at Townsend and Townsend and Crew LLP. Mr. Smith serves on the Board of Directors of two private companies, Theracos Corporation and Arbor Vita Corporation.
Richard DeLateur, the Company’s Chief Financial Officer, currently works four days a week and it is anticipated that Mr. DeLateur’s service will decrease and his employment with the Company will terminate. Mr. DeLateur and the Company do not have a schedule for the eventual termination of Mr. DeLateur’s employment.
2.10 Patents and Other Intangible Assets
2.10(a)
The Company has rights to the patents, trademarks and applications listed on Schedule 2.10 attached hereto, although some of the patent rights listed may not currently be being utilized by the Company in, and may not be necessary for, the Company’s business as now conducted. The Company’s registered domain names are fluidigm.com, fluidigm.net, fluidigm.biz, fluidigm.info and mycometrix.com.

#####

The Company currently is selling two product lines: (i) the Topaz crystallization microprocessors (also referred to as Integrated Fluidic Circuits or IFCs) and certain associated apparatuses; and (ii) the BioMark System, including certain IFCs, such as Dynamic Array chips, Digital Array chips (also referred to as DID chips) and ImmunoMatrix chips, as well as certain associated apparatuses. The Company has not completed investigations with respect to the Intellectual Property Rights required for the BioMark System product line or for additional applications of the Company’s technology. In conjunction with this analysis, the Company has sought and will continue to seek opinions from counsel with respect to potentially relevant third party patent rights directed to, e.g., certain RealTime PCR and other PCR reagents and instruments, such as assigned to Roche Molecular Systems and/or Applied BioSystems, an Applera Corporation Business. The Company, therefore, may need to acquire additional Intellectual Property Rights to pursue those lines of business, particularly with respect to microfluidic devices for PCR and other assays, although the Company has not presently determined that blocking Intellectual Property Rights of others exist in this regard.
The Company has entered into a Collaboration Agreement dated January 24, 2005 (the “CTI Collaboration Agreement”) with CTI Molecular Imaging, Inc. (subsequently acquired by Siemens) (“CTI”), under which the parties are to develop microfluidic chips and associated apparatuses for use in positron emission tomography (“PET”). Under the CTI Collaboration Agreement, both CTI and the Company have granted licenses to the other as necessary to conduct the research and development program contemplated by the CTI Collaboration Agreement. The Company has also granted CTI an option under certain of the Company’s intellectual property to manufacture chips developed during the collaboration. The Company also has rights to intellectual property developed under the Collaboration Agreement, subject to certain restrictions under which CTI and certain other collaborating entities have specified rights in the defined PET and associated fields. Recently, Siemens notified the Company that it does not intend to exercise the option or continue the research and development program. Discussions are underway relating to the early termination of the Collaboration Agreement, and for the Company to obtain all rights to intellectual property developed under the CTI Collaboration Agreement, including intellectual property rights arising from (i) a patent application filed by Siemens and Caltech in which the Company believes that certain Company scientists should have been named as co-inventors; (ii) additional patent applications in the PET field allegedly filed by or on behalf of Siemens potentially with Caltech inventors; and (iii) CTI activities with third parties. The Company and Siemens have agreed starting in 2007 to not engage in further funded research under the CTI Collaboration Agreement.
The Company is licensee under a series of agreements with the President and Fellows of Harvard College, under which the Company pays royalties to Harvard. The Company renegotiated the terms of its agreements with Harvard and reduced the number of licenses from five to three, effective in January 2005. The Company and Harvard will be discussing potential royalty obligations of the Company to Harvard relating to transactions where the Company has received revenue but has not directly charged for product transfers, such as for certain microfluidic chips.
In January 2003, the Company entered into a Patent License Agreement with Gyros pursuant to which the Company received a non-exclusive license to certain patents from Gyros relating to the Company’s products. In exchange for the license, the Company has made certain payments to Gyros. In January 2004, the Company exercised an option to add an additional field of use to the scope of the license agreement in exchange for a cash payment. In January 2007, the Company did not elect or pay for another additional field for, e.g., ImmunoMatrix chips, for which the Company has conducted and is continuing to conduct research and development activities. The Company and Gyros have had discussions regarding the extension of the field and Gyros has offered such extension pursuant to the terms of the Patent License Agreement. In addition, the Company is obligated to make royalty

#####

payments on certain Company products incorporating the technology licensed from Gyros. The amounts otherwise paid by the Company may be used as a credit with respect to the royalty payments. The agreement provides for certain indemnity obligations of the Company.
With respect to certain patent filings then-controlled by Oculus Pharmaceuticals with overlapping claims to the Syrrx patent referred to in the paragraph below, the Company entered into in March 2003 (i) the Master Closing Agreement; (ii) a License Agreement with UABRF (the “UABRF License Agreement”); and (iii) a Sponsored Research Agreement with UABRF. The license is an exclusive license, subject to certain exceptions (including rights UABRF may have previously granted Diversified Scientific, Inc. so that Diversified Scientific could perform research obligations under grants). UABRF and affiliated entities have the right to internal use of the intellectual property rights and to fulfill obligations under a National Institutes of Health grant. Pursuant to the Master Closing Agreement, the Company made an up-front payment to UABRF and granted UABRF shares of the Company’s Series C Preferred Stock. The Company is obligated to issue additional shares of its stock to UABRF in the event certain milestones are achieved as described in Section 2.4 hereof. In connection with the satisfaction of a milestone, the Company may become obligated to enter into a non-transferable site license so that an entity will have the right to use the technology licensed to the Company for internal drug discovery efforts. Pursuant to the Sponsored Research Agreement, the Company agreed to support a UABRF research program. The Sponsored Research Program Agreement contains certain terms relating to the license of intellectual property rights arising out of the program. The Company has certain indemnification obligations pursuant to the agreements referred to in this paragraph.
In conjunction with the development of the Company’s protein crystallization microprocessor prototype, the Company became aware of U.S. Patent no. 6,296,673, issued to the Regents of the University of California (the “Regents”) and apparently exclusively licensed to Syrrx Corporation (note: Sam Colella of Versant Ventures, Chairman of the Company’s Board of Directors, used to be Chairman of Syrrx, which has been acquired by Takeda Pharmaceutical Company Limited). Based on Syrrx’s contentions of infringement with respect to the patent, related patent applications and the Company’s products, the Company has sought and obtained a patent opinion from counsel with respect to the patent and entered into license negotiations with Syrrx for a license/sublicense to the patent and other patent filings assigned to the Regents and Syrrx. In December 2003, the Company entered into a license agreement with Syrrx (the “Syrrx License Agreement”), pursuant to which, in exchange for a field restricted and nonexclusive license under intellectual property owned or controlled by Syrrx, the Company issued Syrrx shares of the Company’s Common Stock, made an up-front payment and annual minimum payments. In addition, the Company is obligated to pay a royalty in connection with the sale of certain products of the Company that incorporate the intellectual property licensed and is obligated to indemnify Syrrx for matters relating to the practice by the Company of any license or sublicense under the agreement. In January 2006, an interference was declared by the USPTO between a patent application licensed to the Company under the UABRF License Agreement and the above-identified patent and other related patents. While the interference was ongoing, the Company, Syrrx, UABRF and Athersys, Inc. (a company that allegedly acquired certain rights from Oculus) were in negotiations to settle the interference and modify the parties’ obligations under the Syrrx License Agreement, the Master Closing Agreement, and the UABRF License Agreement. Recently, in an appealable decision, the USPTO invalidated all claims of both parties in the interference, and Syrrx decided not to appeal. Due to this decision and these negotiations, the Company may decide not to maintain the Syrrx License Agreement in 2008.
The Company is aware of patents and patent applications controlled by Micronics Corporation and Diversified Scientific, Inc. that potentially relate to the Company’s protein crystallization product

#####

line. The Company has sought and obtained opinions from patent counsel regarding such patents and has conducted preliminary discussions with each of these entities regarding the possibility of obtaining a license to the relevant intellectual property. The necessity of obtaining a license from each and the outcome of such negotiations remain uncertain although in certain Micronics patent applications watched by the Company, the claims have been amended to not cover the Company’s protein crystallization product line. In February 2005, Diversified Scientific announced a plan to auction its recently broadened (by USPTO re-examination) patent and other intellectual property related to crystal image analysis. The Company indicated interest to Diversified Scientific in submitting a bid. Diversified Scientific replied that it would respond to the Company and additional interested bidders after checking with their counsel on certain legal issues relating to the apparently improper broadening of patents by re-examination. The Company has not received a further response from Diversified Scientific.
With respect to the patents and patent filings described in the foregoing paragraph, those relating to the BioMark System described above and those not subject to the CTI Collaboration Agreement, there can be no assurance that the Company will be able to obtain licenses on terms acceptable to the Company. In addition, there can be no assurance that the holders of such patents or patent filings will not initiate and prevail in litigation against the Company with respect to the patents or patent filings.
The Company routinely investigates patents held by third parties to determine whether there may be any conflict with the Company Intellectual Property Rights. While such investigations are ongoing, the Company is not currently aware of any conflict except as disclosed herein.
With respect to certain microfluidics protein crystallization technology licensed to the Company from Caltech, a University of California scientist, Dr. James Berger, is a co-inventor of this technology along with certain Caltech scientists. Therefore, the Regents of the University of California own certain rights in the invention which the Company understands have been licensed to Caltech. The Company has sublicensed these rights from Caltech. As the Company is a sublicensee, if Caltech’s license from the Regents were to be revoked or terminated for any reason, the Company’s ability to practice and license this technology internationally would be subject to certain limitations.
See also the discussion of the possible new collaboration agreement in Section 2.17 below, the Company’s license agreement with Caltech in Section 2.10(b) below and the discussion of the Company’s letter from a supplier in Section 2.8 above.
2.10(b)
See Section 2.10(a) above and Schedule 2.10 attached hereto. In addition, in connection with sales of the Company’s products, the Company’s standard terms and conditions include limited licenses to use the Company’s products, including licenses to the Company’s software. The Company also has entered into (i) several prototype and other evaluation agreements and material transfer agreements with third parties, which agreements provide for the third party’s use of the Company’s products for a limited period of time typically in return for grant-back licenses to the Company of improvements, and (ii) material transfer agreements in which the parties may assign to each other certain intellectual property rights. The Company has sold BioMark System prototypes and products and is entering into agreements with respect to additional sales, evaluations and development agreements relating to the BioMark System. The Company typically negotiates either standstill, grant-back or other rights to certain inventions made by the Company or third parties using the prototypes. The Company intends to continue to negotiate collaboration or other agreements with third parties.

#####

The Exclusive Patent License Agreement dated November 2, 2000 with the Regents listed in Schedule 2.10 requires the Company to make efforts to commercialize products relating to the technology licensed to the Company. The Regents sent the Company a notice of termination of the agreement in part due to the alleged failure of the Company to make such efforts. The Regents rescinded the notice of termination and the Company intended to renegotiate the agreement to modify the requirement that the Company make efforts to commercialize the technology. The Company has received a request from the Regents for reports and diligence relating to the agreement. The Company and Regents agreed to terminate the agreement with no further obligations of either party.
In connection with entering into the most recent amendment to the Caltech License Agreement, and in response to a request from Caltech, the Company terminated its license of certain patent rights that it deemed not material to the Company’s business as currently conducted in exchange for a cash payment from Caltech and a reduction in the Company’s potential obligation to issue stock to Caltech. The Company understands that Caltech has licensed these patent rights to another entity, Helicos Biosciences Corporation. Dr. Steve Quake, a former director of and former consultant to the Company, co-founded Helicos, and Versant Ventures, a significant investor in the Company, is also a significant investor in Helicos. The Company believes that a conflict could exist between the license Caltech granted to Helicos and Caltech’s license of patent rights to the Company, if Caltech’s license with Helicos does not specifically exclude the patent rights granted to the Company. The patent rights licensed from Caltech to Helicos include a cross-reference to, and disclosure relating to, the patent rights the Company licenses from Caltech. Effective April 23, 2007, as amended May 11, 2007, the Company executed an Intellectual Property Agreement with Caltech and Helicos.
2.10(c)
See discussions in Sections 2.10(a) and (b) above.

Each such notice shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge in sufficient detail, and shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall be, reasonably satisfactory to the Company, addressed to the Company, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act and applicable state securities laws, or (ii) a “no action” letter from the Commission

-5-

#####

to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, or (iii) any other evidence reasonably satisfactory to counsel to the Company, whereupon the Holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the Holder to the Company; provided, however, that no such legal opinion, “no action” letter or other evidence shall be required with respect to a transfer to an Affiliate. Each certificate evidencing the Restricted Securities transferred as above provided shall bear, except if such transfer is made pursuant to Rule 144, the appropriate restrictive legend set forth in Section 1.3 above, except that such certificate shall not bear such restrictive legend if, in the opinion of counsel for such Holder and reasonably acceptable to the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act or this Agreement.
1.5 Requested Registration.
(a) Request for Registration. In case the Company shall receive from Initiating Holders a written request that the Company effect any registration with respect to a public offering of at least 50% of the Registrable Securities, the reasonably anticipated aggregate price to the public of which, net of underwriting discounts and commissions, would exceed $20,000,000, the Company will:
(i) promptly give written notice of the proposed registration to all other Holders; and
(ii) use its best efforts to effect as soon as practicable such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within 15 days after receipt of the written notice from the Company; provided, however, that the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 1.5:
(1) Prior to six months following the closing of the Company’s Initial Public Offering;
(2) During the period starting with the date 60 days prior to the Company’s estimated date of filing of, and ending on the date three months immediately following the effective date of, any registration statement (other than a registration of Securities in a Rule 145 transaction or with respect to an employee benefit plan) pertaining to Securities of the Company (subject to Section 1.6(a) hereof), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to be filed and become effective and that the Company provides the Initiating Holders written notice of its intent to file such

-6-

#####

registration statement within 30 days of receiving the request for registration from the Initiating Holders and provided further, however, that the Company may not utilize this right more than once in any 12-month period.
(3) After the Company has effected two registrations pursuant to this Section 1.5; or
(4) If the Company shall furnish to such Holders a certificate, signed by the President of the Company, stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its shareholders for a registration statement to be filed in the near future, in which case the Company’s obligation to use its best efforts to register under this Section 1.5 shall be deferred for a period not to exceed 90 days from the date of receipt of written request from the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any 12-month period.
(b) Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made under Section 1.5(a), and the Company shall so advise the Holders as part of the notice given pursuant to Section 1.5(a)(i). The right of any Holder to registration pursuant to Section 1.5 shall be conditioned upon such Holder’s participation in the underwriting arrangements required by this Section 1.5 and the inclusion of such Holder’s Registrable Securities in the underwriting, to the extent requested and provided herein.
The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company and a majority of the Holders. Notwithstanding any other provision of this Section 1.5, if the managing underwriter advises the Company in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities who indicated their intent to participate in the registration in a timely manner, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among such Holders in proportion, as nearly as practicable, to the respective number of Registrable Securities held by such Holders at the time of filing the registration statement, provided, however, that the number of shares of Registrable Securities to be included in such underwriting shall not be reduced unless all Worthington Shares, all Other Shares and all other Securities that are not Registrable Securities (other than Securities to be sold for the account of the Company) are first entirely excluded from the underwriting. No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares.
If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities so withdrawn shall also be withdrawn from registration.

1.6 Company Registration.
(a) Notice of Registration. If at any time or from time to time, the Company shall determine to register any Common Stock, either for its own account or the account of a security holder or holders other than (i) a registration relating to employee benefit plans, (ii) a registration relating to the offer and sale of debt securities, (iii) a registration relating to a Commission Rule 145 transaction, or (iv) a registration pursuant to Sections 1.5 or 1.7 hereof, the Company will:
(i) promptly give to each Holder written notice thereof; and
(ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests made within 15 days after receipt of such written notice from the Company by any Holder.
(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders in a written notice given pursuant to this Section 1.6. In such event, the right of any Holder to registration pursuant to this Section 1.6 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein.
All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company. Notwithstanding any other provision of this Section 1.6, if the managing underwriter advises the Company in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all Holders thereof in proportion, as nearly as practicable, to the respective number of Registrable Securities held by such Holders at the time of filing the registration statement; provided, however, that, no Registrable Securities shall be excluded until all Worthington Shares, all Other Shares and all other Securities that are not Registrable Securities (other than Securities to be sold for the account of the Company) are first excluded, and provided further, that, except in the case of the Company’s Initial Public Offering (where Registrable Securities may be excluded entirely), the number of Registrable Securities included in such underwriting shall not be reduced below 25% of the total number of shares in the underwriting. No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. The Company may include shares of Common Stock held by shareholders other than Holders in a registration statement pursuant to this Section 1.6 to the extent that the amount of Registrable Securities otherwise includible in such registration statement would not thereby be diminished.

-8-

#####

If any Holder or other holder disapproves of the terms of any such underwriting, he or she may elect to withdraw therefrom by written notice to the Company and the managing underwriter. The Registrable Securities so withdrawn shall also be withdrawn from such registration and, in the case of the Company’s Initial Public Offering, shall be subject to Section 1.14.
(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1.6 prior to the effectiveness of such registration, whether or not any Holder has elected to include securities in such registration.
1.7 Registration on Form S-3.
(a) If any Holder or Holders request that the Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of Registrable Securities, the reasonably anticipated aggregate price to the public of which, net of underwriting discounts and commissions, would exceed $2,000,000, and the Company is then entitled to use Form S-3 under applicable Commission rules to register the Registrable Securities for such an offering, the Company will:
(i) promptly give written notice of the proposed registration to all other Holders; and
(ii) use its best efforts to effect as soon as practicable such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within 15 days after receipt of the written notice from the Company; provided, however, that the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 1.7:
(1) if the Company, within ten (10) days of the receipt of the request for registration pursuant to this Section 1.7, gives notice of its bona fide intention to effect the filing of a registration statement with the Commission within ninety (90) days of receipt of such request (other than with respect to a registration statement relating to a Rule 145 transaction or an employee benefit plan or any other registration which is not appropriate for the registration of Registrable Securities);
(2) during the period starting with the date sixty (60) days prior to the Company’s estimated date of filing of, and ending on the date three months immediately following, the effective date of any registration statement pertaining to Securities of the Company (other than with respect to a registration statement relating to a Rule 145 transaction or an employee benefit plan), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to be filed and become effective; or

#####

(3) if the Company shall furnish to such Holder or Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its shareholders for registration statements to be filed in the near future, then the Company’s obligation to use its best efforts to file a registration statement shall be deferred for a period not to exceed 90 days from the receipt of the request to file such registration by such Holder or Holders; provided further, however, that the Company may not utilize the rights provided for in subsections (1) and (2) above and this subsection (3) more than once in total in any twelve month period. For the avoidance of doubt, if the Company utilizes any of the rights provided for in subsections (1), (2) and (3), it shall not have the right to utilize the same right again; nor shall it have the right to utilize any of the other rights provided in subsections (1), (2) and (3) for twelve months.
(b) Underwriting. If the Holders requesting registration intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made under Section 1.7(a), and the Company shall so advise the Holders as part of the notice given pursuant to Section 1.7(a)(i). The substantive provisions of Section 1.5(b) shall otherwise apply to such registration.
1.8 Expenses of Registration. All Registration Expenses incurred in connection with any registration pursuant to Sections 1.5, 1.6 and 1.7 shall be borne by the Company. If a registration proceeding is begun upon the request of Holders pursuant to Section 1.5 or 1.7, but such request is subsequently withdrawn at the request of the Holders, then the Holders of Registrable Securities to have been registered may either: (i) bear all Registration Expenses of such proceeding, pro rata on the basis of the number of shares to have been registered, in which case the Company shall be deemed not to have effected a registration pursuant to Section 1.5(a) or 1.7(a) of this Agreement as applicable; provided, however, that the Company, and not the Holders, shall be required to pay for the Registration Expenses if the Holders learn of a materially adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request promptly following discovery of such material adverse change; or (ii) if the registration is being effected pursuant to Section 1.5, require the Company to bear all Registration Expenses of such proceeding, in which case the Company shall be deemed to have effected a registration pursuant to Section 1.5(a). Unless otherwise stated, all other Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the Holders of the registered securities included in such registration pro rata on the basis of the number of shares so registered, provided that to the extent a Holder elects to retain its own counsel (an “Additional Counsel”) separate from the counsel for all the Holders permitted pursuant to the definition of “Registration Expenses” under Section 1.1, then such Holder shall exclusively bear the costs of such Additional Counsel.
1.9 Registration Procedures. In the case of each registration, qualification or compliance effected by the Company pursuant to this Section 1, the Company will keep each Holder advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense the Company will, as expeditiously as reasonably possible:

(b) Prepare and file with the Commission, in consultation with the Holders, such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement.

(e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

1.10 Indemnification.
(a) The Company will indemnify and defend each Holder, each of its officers and directors and partners, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance is being effected pursuant to this Section 1, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation or any alleged violation by the Company of the Securities Act or the Exchange Act or any state securities law, or any rule or regulation promulgated thereunder, applicable to the Company in connection with any such registration, qualification or compliance, and the Company will reimburse each such Holder, each of its officers and directors, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder, controlling person or underwriter and stated to be specifically for use therein.

(b) Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, each of its officers and directors and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company, such Holders, such directors, officers, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, as such expenses are incurred, in each case to the extent, but only if and to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder and stated to be specifically for use therein; provided, however, that the liability of any Holder shall be limited to the net proceeds received by such Holder from the sale of Securities pursuant to such registration.
(c) Each party entitled to indemnification under this Section 1.10 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party’s expense; provided, however, that an Indemnified Party (together with all other Indemnified Parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 1 unless, and only to the extent that, the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.
(d) If the indemnification provided for in this Section 1.10 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss,

-13-

#####

liability, claim, damage, or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations (except to the extent that contribution is not permitted under Section 11(f) of the Securities Act); provided, however, that, no Holder will be required to pay any amount under this subsection 1.10(d) in excess of the net proceeds from the sale of all Registrable Securities offered and sold by such Holder pursuant to such registration statement. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.
(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control with respect to the rights and obligations of each of the parties to such underwriting agreement.
(f) The obligations of the Company and Holders under this Section 1.10 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1, and otherwise.
1.11 Information by Holder. The Holder or Holders of Registrable Securities included in any registration shall furnish to the Company such information regarding such Holder or Holders, the Securities held by them and the distribution proposed by such Holder or Holders as the Company may reasonably request in writing and as shall be required in connection with any registration referred to in this Section 1.
1.12 Reports Under Securities Exchange Act of 1934. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the Commission that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to use its best efforts to:

The rights to cause the Company to register Registrable Securities granted to the Investors under Sections 1.5, 1.6 and 1.7 may be assigned to a transferee or assignee in connection with any transfer or assignment of Eligible Securities by an Investor; provided that (a) such transfer may otherwise be effected in accordance with applicable securities laws, (b) notice of such assignment is given to the Company, (c) such transferee is a Permitted Transferee and (d) such transferee or assignee agrees to be bound by and subject to the terms and conditions of this Agreement.
1.14 Standoff Agreement.
(a) Each Holder agrees in connection with the first sale of the Company’s Common Stock in a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act, upon notice by the Company or the underwriters managing such public offering, not to sell, make any short sale of, loan, pledge (or otherwise encumber or hypothecate), grant any option for the purchase of, or otherwise directly or indirectly dispose of any Securities (other than those included in the registration) without the prior written consent of the Company and such managing underwriters for such period of time as the Board of Directors establishes pursuant to its good faith negotiations with such managing underwriters; provided, however that:
(i) such agreement shall not exceed one hundred eighty (180) days;
(ii) such agreement shall not apply to transfers to an Affiliate, provided that such Affiliate agrees to be bound by the terms of such agreement, to the same extent as if such transferee were the original party thereunder;

(iv) if and when any person identified in clause (iii) is released, in whole or in part, from such agreement (whether or not such release is contemplated at the time of the offering) or if any such agreement is terminated, the Holder shall be concurrently released on a pro rata basis based on the number of shares held by such person and the Holder.
(b) Each Holder agrees that prior to the Initial Public Offering it will not transfer securities of the Company unless each transferee agrees in writing to be bound by all of the provisions of this Section 1.14; provided that this Section 1.14(b) shall not apply to transfers pursuant to a registration statement.
(c) Each Holder hereby consents to the placement of stop transfer orders with the Company’s transfer agent in order to enforce the foregoing provision and agrees to execute a market standoff agreement with said underwriters in customary form consistent with the provisions of this Section 1.14.

All other provisions hereof relating to registration rights shall continue to be effective despite any termination of such registration rights pursuant to this section.
1.17 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not enter into any agreement granting any holder or prospective holder of any securities of the Company registration rights with respect to such securities unless (i) such new registration rights, are subordinate to the registration rights granted Holders hereunder and include similar market stand-off obligations or (ii) such new registration rights are approved by the Holders of 50% of the Registrable Securities then held by Holders (assuming exercise or conversion of all outstanding Eligible Securities); provided, however, that Warrantholders may enter into this Agreement by executing and delivering a counterpart signature page to this Agreement.

An Investor shall be entitled to apportion the right of first offer hereby granted among itself and its partners and Affiliates in such proportions as it deems appropriate.

(a) The Company shall deliver a notice (“Notice”) to each Investor stating (i) its intention to offer such Securities for sale, (ii) the number of such Securities to be offered (the “Offered Securities”), (iii) the price, if any, for which it proposes to offer such Securities, (iv) the terms of such offer and (v) the Offer Amount (as defined below).

-19-

#####

(b) Within fifteen (15) calendar days after receipt of the Notice, each Investor may elect to purchase, at the price and on the terms specified in the Notice, such Securities in an amount up to the Offer Amount by providing the Company with written notice of its election.
(c) An election by an Investor pursuant to Section 3.1(b) to purchase Offered Securities shall not be considered a binding commitment on the Investor unless and until the Company receives binding commitments to purchase on the terms and conditions contained in the Notice substantially all of the Offered Securities which the Investors have not elected to purchase.
Notwithstanding the foregoing, the Company and each of the Investors acknowledge and agree that Lighthouse shall have the opportunity to invest not less than $250,000 in connection with the first Financing completed after the date of this Agreement that involves the sale and issuance by the Company of shares of the Company’s convertible preferred stock with aggregate gross proceeds to the Company of at least $3 million. In the event that Lighthouse’s right to purchase Offered Securities as otherwise set forth in this Section 3.1 would not permit such $250,000 investment, then each of the Investors agrees that its respective right to purchase Offered Securities pursuant to this Section 3.1 may be cut-back (proportionately with all other Investors based on the number of shares of Eligible Securities held by the Investors) in such amounts as may be necessary to permit the exercise of Lighthouse’s rights as set forth herein.
3.2 Sale of Securities by Company.

If the Company does not complete the sale of all such Offered Securities within said 60-day period, the rights of the Investors with respect to any such unsold Offered Securities shall be deemed to be revived.
3.3 Offer Amount. The “Offer Amount” shall equal that percentage of the Offered Securities equal to the number of shares of Eligible Securities held by an Investor which are Registrable Securities divided by the total number of outstanding shares of Common Stock of the Company. For the purposes of the foregoing calculations, all outstanding options and warrants shall be deemed to be exercised and all Preferred Stock shall be deemed to have been converted into Common Stock at the prevailing conversion rate.
3.4 Financing. “Financing” shall mean an offering or series of related offerings of Securities by the Company for purposes of raising working capital in a minimum amount of $250,000. Financing shall not include (i) the issuance or sale of shares of Common Stock or options to purchase Common stock to employees, officers, directors or consultants for the primary purpose of soliciting or retaining their services in such amount as shall have been approved by the Board of Directors, (ii) the issuance or sale of Securities to leasing entities or financial institutions in connection with commercial leasing or borrowing transactions approved by the Board of Directors, (iii) the issuance or sale of Securities to third party providers of goods or services in connection with transactions approved by the Board of Directors; (iv) the sale of Securities in a registered public offering, (v) any issuances of Securities in connection with any stock split, stock dividend or recapitalization by the Company, (vi) the issuance of Securities at a price (on an as converted to

Should a Founder (a “Seller”) propose to accept one or more bona fide offers (collectively, the “Purchase Offer”) from any persons (“Purchasers”) to purchase Founders Shares from such Seller (other than as set forth 4.2(d) hereof), then such Seller shall, promptly after exercise or termination of any rights of first refusal held by the Company, deliver a notice (the “Notice”) to the Company and all Investors holding more than 750,000 shares of Eligible Securities (“Eligible Investors”).
4.2 Purchase Right. Each Eligible Investor shall have the right, exercisable upon written notice to such Seller within ten (10) business days after receipt of the Notice, to purchase Founders Shares on the terms and conditions specified in the Purchase Offer. To the extent an Eligible Investor exercises its right to purchase such shares in accordance with the terms and conditions set forth below, the number of shares of stock which such Seller may sell to the Purchasers pursuant to the Purchase Offer shall be correspondingly reduced. The purchase right of each Eligible Investor shall be subject to the following terms and conditions:
(a) Calculation of Shares.

For the purposes of the foregoing calculations, all outstanding options and warrants shall be deemed to be exercised and all Preferred Stock shall be deemed to have been converted into Common Stock at the prevailing conversion rate.
(b) Delivery of Consideration. Each Eligible Investor may effect its purchase right by promptly delivering to such Seller a written notice and a check or wire transfer equal to the purchase price specified in the Purchase Offer for the number of shares the Eligible Investor desires to purchase pursuant to this Section 4.2.

(iii) Any exercise by the Company of a right or remedy under the terms of any loan, security or stock pledge agreement where the Founders Shares serve as security for a loan made by the Company;

(v) Any bona fide gift;
provided, however, that such Founder shall inform the Eligible Investors of such transfer or gift (other than a transfer pursuant to clause (ii) or (iii)) prior to effecting it and the transferee or donee (if other than the Company) shall furnish the Company and the Eligible Investors with a written agreement to be bound by and comply with all applicable provisions of this Agreement.
4.3 Sale of Securities by Founder. Within 60 days of the expiration of the period described in the first paragraph of Section 4.2, any Founders Shares covered by the Purchase Offer which the Eligible Investors have not elected to purchase may be sold by the Seller to the Purchasers on the terms and conditions of the Purchase Offer. If the Seller does not complete the sale of all Founders Shares covered by the Purchase Offer within such period, the rights of the Eligible Investors with respect to any such unsold Founders Shares shall be deemed to be revived.
4.4 Termination and Transfer. The restrictions imposed and rights granted by this Section 4 shall not apply to and shall terminate immediately prior to the closing of the Company’s Initial Public Offering. Securities received pursuant to any stock dividend, stock split, recapitalization, or exercise of a conversion right shall be subject to this Section 4 to the same extent as the shares of the Company with respect to which they were issued. The right of first offer granted under this Section 4 is transferable to transferees of at least 750,000 shares of Registrable Securities (as adjusted for stock splits, combinations and the like) or to Affiliates.
4.5 Prohibited Transfer. Any attempt by a Founder to transfer Founders Shares in violation of Section 4 hereof shall be void and the Company agrees it will not effect such a transfer nor will it treat any alleged transferee(s) as the holder of such shares, without the written consent of two-thirds (2/3) in interest of the Eligible Investors.

Right of Co-Sale
5.1 Notice of Sales.

5.2 Participation Right. Each Eligible Investor shall have the right, exercisable upon written notice to such Seller within fifteen (15) business days after receipt of the Notice, to participate in such Seller’s sale of stock pursuant to the specified terms and conditions of such Purchase Offer. To the extent an Eligible Investor exercises such right of participation in accordance with the terms and conditions set forth below, the number of shares of stock which such Seller may sell pursuant to such Purchase Offer shall be correspondingly reduced. The right of participation of each Eligible Investor shall be subject to the following terms and conditions:
(a) Calculation of Shares.

(c) Transfer. The stock certificate or certificates which the Eligible Investor delivers to such Seller pursuant to Section 5.2 shall be delivered by the Seller to the Purchaser(s) in consummation of the sale of the Securities pursuant to the terms and conditions specified in the Notice, and such Seller shall promptly thereafter remit to such Eligible Investor that portion of the sale proceeds to which such Eligible Investor is entitled by reason of its participation in such sale.

(i) Any transfer to a revocable grantor trust with respect to which the Seller and members of his family are the sole beneficiaries;

5.3 Sale of Securities by Founder. Within 45 days of the expiration of the period described in the first paragraph of Section 5.2, any Founders Shares covered by the Purchase Offer which the Eligible Investors have not elected to purchase may be sold by the Seller to the Purchasers on the terms and conditions of the Purchase Offer.

5.4 Termination and Transfer. The restrictions imposed and rights granted by this Section 5 shall not apply to and shall terminate immediately prior to the closing of the Company’s Initial Public Offering. Securities received pursuant to any stock dividend, stock split, recapitalization, or exercise of a conversion right shall be subject to this Section 5 to the same extent as the shares of the Company with respect to which they were issued. The co-sale right granted under this Section 5 is transferable to transferees of at least 750,000 shares of Registrable Securities (as adjusted for stock splits, combinations and the like) or to Affiliates.
5.5 Prohibited Transfers.
(a) In the event any Founder should sell any Founders Shares in contravention of the co-sale rights of the Investors under Section 5 (a “Prohibited Transfer”), the Investors, in addition to such other remedies as may be available at law, in equity or hereunder, shall have the put option provided below, and the Founder shall be bound by the applicable provisions of such option.
(b) In the event of a Prohibited Transfer, each Eligible Investor shall have the right to sell to the Founder the type and number of shares of Common Stock equal to the number of shares that such Eligible Investor would have been entitled to transfer to the third-party transferee(s) under Section 5.2 hereof had the Prohibited Transfer been effected pursuant to and in compliance with the terms thereof. Such sale shall be made on the following terms and conditions:
(i) The price per share at which the shares are to be sold to the Founder shall be equal to the price per share paid by the third-party transferee(s) to the Founder in the Prohibited Transfer. Such price per share shall be paid to the Eligible Investor in cash if the Founder received cash for his shares. If the Founder did not receive cash but received other property instead, the price per share to be paid to the Eligible Investor shall be paid (A) in the form of the property received by the Founder for his shares, or (B) in cash equal to the fair market value of the property received by such Founder as determined in good faith by the Company’s Board of Directors, at the option of the Eligible Investor. The Founder shall also reimburse each Eligible Investor for any and all fees and expense, including legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of the Eligible Investor’s rights under Section 5.

(ii) Within thirty (30) days after the later of the dates on which the Eligible Investor (A) received notice of the Prohibited Transfer or (B) otherwise became aware of the Prohibited Transfer, each Eligible Investor shall, if exercising the option created hereby, deliver to the Founder the certificate or certificates representing shares to be sold, each certificate to be properly endorsed for transfer.
(iii) The Founder shall, upon receipt of the certificate or certificates for the shares to be sold by an Eligible Investor pursuant to this Section 5, pay the aggregate purchase price therefor and the amount of reimbursable fees and expenses, as specified in subparagraph 5.5(b)(i), in cash or by other means acceptable to the Eligible Investor.
(c) Notwithstanding the foregoing, any attempt by a Founder to transfer Founders Shares in violation of Section 5 hereof shall be void and the Company agrees it will not effect such a transfer nor will it treat any alleged transferee(s) as the holder of such shares, without the written consent of two-thirds (2/3) in interest of the Eligible Investors.

EXHIBIT E
FORM OF LEGAL OPINION

#####

June , 2006
AllianceBernstein L.P.
1345 Avenue of the Americas
New York, New York 10105
Ladies and Gentlemen:
Reference is made to the Series E Preferred Stock Purchase Agreement dated as of June , 2006 (the “Agreement”) by and among Fluidigm Corporation, a California corporation (the “Company”), and the persons and entities listed in Exhibit A to the Agreement (the “Investors”), which provides for the issuance by the Company to the Investors of shares of Series E Preferred Stock of the Company (the “Shares”). This opinion is rendered to the Investors in the Initial Closing pursuant to Section 4.5 of the Agreement, and all terms used herein have the meanings defined for them in the Agreement unless otherwise defined herein. Reference in this opinion to the Agreement excludes any schedule or substantive agreement attached as an exhibit to the Agreement, unless otherwise indicated herein.
We have acted as counsel for the Company in connection with the negotiation of the Agreement and the Investor Rights Agreement (collectively, the “Transaction Documents”) and the issuance of the Shares. As such counsel, we have made such legal and factual examinations and inquiries as we have deemed advisable or necessary for the purpose of rendering this opinion. In addition, we have examined originals or copies of such corporate records of the Company, certificates of public officials and such other documents which we consider necessary or advisable for the purpose of rendering this opinion. In such examination we have assumed the genuineness of all signatures on original documents, the authenticity and completeness of all documents submitted to us as originals, the conformity to original documents of all copies submitted to us and the due execution and delivery of all documents (except as to due execution and delivery by the Company) where due execution and delivery are a prerequisite to the effectiveness thereof.
As used in this opinion, the expression “to our knowledge,” “known to us” or similar language with reference to matters of fact refers to the current actual knowledge of attorneys of this firm who have worked on matters for the Company in connection with the Agreement and the transactions contemplated thereby. Except to the extent expressly set forth herein or as we otherwise believe to be necessary to our opinion, we have not undertaken any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the rendering of the opinion set forth below.

For purposes of this opinion, we are assuming that each Investor has all requisite power and authority, and has taken any and all necessary corporate or partnership action, to execute and deliver the Transaction Documents and to effect any and all transactions related to or contemplated thereby. In addition, we are assuming that the Investors have purchased the Shares for value, in good faith and without notice of any adverse claims within the meaning of the California Uniform Commercial Code.
We are members of the Bar of the State of California and we express no opinion as to any matter relating to the laws of any jurisdiction other than the federal laws of the United States of America and the laws of the State of California.
In rendering the opinion in paragraph 6 below, we note that we have not conducted a docket search in any jurisdiction with respect to litigation that may be pending against the Company or any of its officers or directors. We further note the disclosure under Section 2.10 of the Schedule of Exceptions to the Agreement. Please be advised that we have not represented the Company with respect to the matters disclosed in Section 2.10 of the Schedule of Exceptions and express no opinion with respect to any matter discussed therein.
The opinions hereinafter expressed are subject to the following additional qualifications:
(a) We express no opinion as to the effect of applicable bankruptcy, insolvency, reorganization, moratorium or other similar federal or state laws affecting the rights of creditors.
(b) We express no opinion as to the effect or availability of rules of law governing specific performance, injunctive relief or other equitable remedies (regardless of whether any such remedy is considered in a proceeding at law or in equity).
(c) This opinion is qualified by the limitations imposed by statutes and principles of law and equity that provide that certain covenants and provisions of agreements are unenforceable where such covenants or provisions are unconscionable or contrary to public policy or where enforcement of such covenants or provisions under the circumstances would violate the enforcing party’s implied covenant of good faith and fair dealing.
(d) Our opinion in the first sentence of paragraph 1 below is based solely on the certificates of public officials and filing officers as to the corporate and tax good standing of the Company in the State of California.
(e) Our opinions set forth in paragraph 3 below relating to the outstanding capital stock of the Company and outstanding options, warrants or similar rights to acquire shares of the Company’s capital stock are based solely on (i) our review of a report from eProsper, Inc., the

Company’s transfer agent, detailing the holders of securities of the Company and the number and type of securities held by such holders (the “Transfer Agent Report”) and (ii) a certificate delivered to us by the Company regarding factual matters underlying the opinions set forth herein. Our opinion in paragraph 3 below that the issued and outstanding shares of Common Stock and Preferred Stock of the Company are fully paid and non-assessable is based solely on a certificate of an officer of the Company that the Company received, in payment for such shares, the full consideration required by the resolutions of the Board of Directors of the Company authorizing the issuance of such shares.
(f) For purposes of our opinions in paragraph 2 and paragraph 4 below, we have assumed that the Transfer Agent Report is accurate and complete in all respects.
(g) We express no opinion as to compliance with the anti-fraud provisions of applicable securities laws.
(h) We express no opinion as to the enforceability of any indemnification or contribution provision, including, without limitation, the indemnification and contribution provisions of the Investor Rights Agreement and the indemnification provision in the Agreement, to the extent the provisions thereof may be subject to limitations of public policy and the effect of applicable statutes and judicial decisions.
(i) We express no opinion as to the enforceability of choice of law provisions, waivers of jury trial or provisions relating to venue or jurisdiction.
(j) We have made no inquiry into, and express no opinion with respect to, any federal or state statute, rule, or regulation relating to any tax, antitrust, land use, safety, environmental, hazardous material, patent, copyright, trademark or trade name matter, as to the statutes, regulations, treaties or common laws of any other nation (other than the United States), state or jurisdiction (other than the State of California), or the effect on the transactions contemplated in the Transaction Documents of noncompliance under any such statues, regulations, treaties, or common laws. Without limiting the foregoing, we express no opinion as to the effect of, or compliance with, the Investment Advisors Act of 1940, as amended, or the Employee Retirement Income Security Act of 1974, as amended. We further disclaim any opinion as to any statute, rule, regulation, ordinance, order, or other promulgation of any regional or local governmental body or as to any related judicial or administrative opinion.
(k) Our opinions relate solely to the express written provisions of the Transaction Documents, and we express no opinion as to any other oral or written agreements or understandings between the Company or any of the Investors.

Based upon and subject to the foregoing, and except as set forth in the Schedule of Exceptions to the Agreement, we are of the opinion that:
1. The Company is a corporation duly incorporated and validly existing under, and by virtue of, the laws of the State of California and is in good standing under such laws. The Company has requisite corporate power to own and operate its properties and assets, and to carry on its business as presently conducted.
2. The Company has all requisite legal and corporate power to execute and deliver the Transaction Documents, to sell and issue the Shares under the Agreement, to issue the Common Stock issuable upon conversion of the Shares and to carry out and perform its obligations under the terms of the Transaction Documents.
3. The authorized capital stock of the Company consists of 77,857,144 shares of Common Stock, 9,274,356 shares of which are issued and outstanding, and 51,687,948 shares of Preferred Stock, 2,727,273 of which are designated Series A Preferred Stock, 2,727,273 shares of which are issued and outstanding, 6,460,675 of which are designated Series B Preferred Stock, 6,460,675 shares of which are issued and outstanding, 17,000,000 of which are designated Series C Preferred Stock, 16,364,832 shares of which are issued and outstanding, 15,500,000 shares of Series D Preferred Stock, 11,714,048 of which are issued and outstanding, and 10,000,000 shares of Series E Preferred Stock, none of which has been issued or outstanding immediately prior to the Initial Closing. All such issued and outstanding shares of Common Stock and Preferred Stock have been duly authorized and validly issued and are fully paid and nonassessable. The Company has reserved: (i) 5,000,000 shares of Series E Preferred Stock for issuance pursuant to the Agreement and 5,000,000 shares of Common Stock for issuance upon conversion of such shares of Series E Preferred Stock; (ii) 11,714,048 shares of Common Stock for issuance upon conversion of the Series D Preferred Stock, (iii) 916,335 shares of Series D Preferred Stock for issuance upon exercise of outstanding warrants and 916,335 shares of Common Stock for issuance upon conversion of such Series D Preferred Stock; (iv) 16,364,832 shares of Common Stock for issuance upon conversion of the Series C Preferred Stock; (v) 294,868 shares of Series C Preferred Stock for issuance upon exercise of outstanding warrants and 294,868 shares of Common Stock for issuance upon conversion of such Series C Preferred Stock; (vi) 6,460,675 shares of Common Stock for issuance upon conversion of the Series B Preferred Stock; (vii) 2,727,273 shares of Common Stock for issuance upon conversion of the Series A Preferred Stock; and (viii) an aggregate of 10,800,000 shares of Common Stock for issuance to employees and consultants of the Company pursuant to the Company’s 1999 Stock Option Plan (the “Option Plan), pursuant to which options to purchase 5,597,763 shares are granted and outstanding and 1,554,643 shares are available for future grant. The Common Stock issuable upon conversion of the Shares has been duly authorized and duly and validly reserved, and when issued in accordance with the Company’s Articles of Incorporation, will

be validly issued, fully paid and nonassessable. The Shares issued under the Agreement are duly authorized, validly issued, fully paid and nonassessable and are free of any liens, encumbrances and preemptive or similar rights contained in the Articles of Incorporation or Bylaws of the Company, or, to our knowledge, in any written agreement to which the Company is a party, except as specifically provided in the Agreement (including its Exhibits) and except for liens or encumbrances created by or imposed upon the Investors; provided, however, that the Shares (and the Common Stock issuable upon conversion thereof) are subject to restrictions on transfer under applicable state and federal securities laws. To our knowledge, except for rights described above, in the Transaction Documents (including the Schedule of Exceptions to the Agreement) or in the Articles of Incorporation of the Company, as of the date of the Agreement, there are no other options, warrants, conversion privileges or other rights in writing presently outstanding to purchase or otherwise acquire any authorized but unissued shares of capital stock or other securities of the Company, or any other written agreements of the Company to issue any such securities or rights; provided, however, we note the Company’s intent to comply with Section 3 of the Investor Rights Agreement following the Initial Closing.
4. All corporate action on the part of the Company, its directors and shareholders necessary for the authorization, execution and delivery of the Transaction Documents by the Company, the authorization, sale, issuance and delivery of the Shares (and the Common Stock issuable upon conversion thereof) and the performance by the Company of its obligations under the Transaction Documents (other than those registration obligations contained in Section 1 of the Investor Rights Agreement) has been taken. The Transaction Documents have been duly and validly executed and delivered by the Company and constitute a valid and binding obligation of the Company, enforceable against the Company in accordance with their terms.
5. The execution and delivery by the Company of the Transaction Documents, the performance by the Company of its obligations under the Transaction Documents, and the issuance of the Shares (and the Common Stock issuable upon conversion thereof) do not violate any provision of the Articles of Incorporation or Bylaws, or any provision of any applicable federal or state law, rule or regulation known to us to be customarily applicable to transactions of this nature. The execution and delivery by the Company of the Transaction Documents, the performance by the Company of its obligations under the Transaction Documents, and the issuance of the Shares (and the Common Stock issuable upon conversion thereof) do not violate any judgment or decree known to us that is binding upon the Company.
6. Except as identified in the Agreement (including the Schedule of Exceptions), to our knowledge, there are no actions, suits, proceedings or investigations pending against the Company or its properties before any court or governmental agency nor, to our knowledge, has the Company received any written threat thereof.

No consent, approval or authorization of or designation, declaration or filing with any governmental authority on the part of the Company is required in connection with the valid execution and delivery of the Transaction Documents, or the offer, sale or issuance of the Shares (and the Common Stock issuable upon conversion thereof) or the consummation by the Company of any other transaction contemplated by the Transaction Documents, except (a) the filing of the Amended and Restated Articles of Incorporation in the Office of the Secretary of State of the State of California, and (b) subject to the accuracy of the representations and warranties of the Investors in Section 3 of the Agreement, (i) the filing after the Closing of a Form D pursuant to Regulation D, promulgated by the United States Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”), with the SEC, and (ii) the post-Closing qualification (or the taking of such action post-Closing as may be necessary to secure an exemption from qualification) under applicable state securities laws of the offer and sale of the Shares (and the Common Stock issuable upon conversion thereof). The filing referred to in clause (a) above has been accomplished and is effective. Our opinion herein is otherwise subject to the timely and proper completion of all filings and other actions contemplated herein where such filings and actions are to be undertaken on or after the date hereof.
8.

This opinion is furnished to the Investors solely for their benefit in connection with the purchase of the Shares, and may not be relied upon by any other person or for any other purpose without our prior written consent. We assume no obligation to inform you of any facts, circumstances, events or changes in the law that may arise or be brought to our attention after the date of this opinion that may alter, affect or modify the opinions expressed herein.
