A. The parties intend that, subject to the terms and conditions hereinafter set forth, Merger Sub shall merge with and into the Company (the “Merger”), with the Company to be the surviving corporation of the Merger (the “Surviving Corporation”), on the terms and subject to the conditions of this Agreement and pursuant to the applicable provisions of the General Corporation Law of the State of Delaware (“Delaware Law”).

B. The Boards of Directors of Parent, Merger Sub and the Company have determined that the Merger is in the best interests of their respective stockholders and have approved and declared advisable this Agreement and the Merger.

D. Concurrently with the execution and delivery of this Agreement, and as a condition and material inducement to the Company’s willingness to enter into this Agreement, each Parent stockholder listed on Annex B is executing and delivering to the Company a Parent Voting Agreement in substantially the form attached hereto as Exhibit B (a “Parent Voting Agreement”).

E. For United Stated federal income tax purposes, Parent, Merger Sub and the Company intend that the Merger qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

F. Parent, Merger Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger and to prescribe various conditions to the Merger.

NOW, THEREFORE, in consideration of the foregoing and the mutual promises, covenants and conditions contained herein, the parties hereby agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Upon the terms and subject to satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with Delaware Law, Merger Sub, at the Effective Time, shall be merged with and into the Company. As a result of the Merger, the Surviving Corporation shall be a wholly owned subsidiary of Parent.

1.2 Closing. Subject to termination of this Agreement as provided in Article VIII, the closing of the Merger (the “Closing”) shall take place on the first business day after the satisfaction or waiver of the conditions (excluding conditions that, by their nature, cannot be satisfied until the Closing Date) set forth in Article VI, or on such time or date as agreed to in writing by the parties hereto (the actual date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of Heller Ehrman LLP, 275 Middlefield

Road, Menlo Park, California, unless another place is agreed to in writing by the parties hereto. As soon as practicable on or after the Closing Date, the parties hereto shall cause the Merger to be consummated by filing a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with the relevant provisions of, Delaware Law (the date and time of such filing, or if another date and time is specified in such filing, such specified date and time, being the “Effective Time”).

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, at the Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Certificate of Incorporation; By-laws. At the Effective Time, (i) the Certificate of Incorporation of the Surviving Corporation shall be amended and restated in its entirety to read in form and substance substantially the same as Exhibit C hereto and (ii) the By-laws of the Surviving Corporation shall be amended and restated in their entirety to read in form and substance substantially the same as Exhibit D hereto, in each case until thereafter changed or amended as provided therein or applicable Law.

1.5 Directors and Officers of Surviving Corporation. At the Effective Time, the initial directors of the Surviving Corporation shall be the persons designated on Annex C hereto, each to hold office in accordance with the Certificate of Incorporation and By-laws of the Surviving Corporation, as amended. The initial officers of the Surviving Corporation shall be the persons designated on Annex C hereto, each to hold office in accordance with the Certificate of Incorporation and By-laws of the Surviving Corporation, as amended.

1.6 Directors; Officers. The parties will take all action necessary such that as of the Effective Time the Board of Directors of Parent shall consist of the nine (9) members, eight (8) of which shall be those persons set forth on Annex D hereto (it being understood that prior to the Effective Time the persons set forth on Annex D may only be changed by mutual written consent of the parties). The parties agree that the eight (8) persons set forth on Annex D shall (x) designate the class of director and the committees to which each such director will initially belong prior to the initial filing of the Registration Statement and (y) expeditiously designate the one (1) remaining member of the Board of Directors of Parent. The parties shall take such action as is necessary to structure the Board of Directors of Parent to satisfy applicable stock exchange and corporate governance requirements.

1.7 Establishment of the Escrow Fund. On the Closing Date, Parent will deposit the Escrow Shares with the Escrow Agent to provide for the indemnification rights of Parent under Article 8. The fund comprised of the Parent Common Stock deposited with the Escrow Agent by Parent in accordance with this Section 1.7 is referred to in this Agreement as the “Escrow Fund” and the disposition of the Escrow Fund will be governed by the terms of this Agreement and the Escrow Agreement. Each Participating Stockholder will be entitled to receive such Participating Stockholder’s Pro Rata Share of any amounts that are released from the Escrow Fund to the Participating Stockholders in accordance with the terms of this Agreement and the Escrow Agreement.

1.8 Escrow; Indemnity; Stockholder Representative. The Participating Stockholders, by virtue of the approval of this Agreement by the Company stockholders, (i) shall be deemed to have consented to the deposit of the Escrow Shares with the Escrow Agent pursuant to the terms of the Escrow Agreement, (ii) shall be deemed to have agreed that the Escrow Shares in the Escrow Fund will be subject to the indemnification provisions of Article 8, and (iii) shall be deemed to have irrevocably constituted and appointed the Stockholder Representative (together with his or her permitted successors) as their true and lawful agent and attorney-in-fact to enter into the Escrow Agreement, to enter into any other agreement in connection with the transactions contemplated by this Agreement, to exercise all or any of the powers, authority and discretion conferred on the Stockholder Representative under any such agreement, to waive any terms and conditions of any such agreement, to give and

receive notices on their behalf and to be their exclusive representative to the extent of their respective interests in the Escrow Fund with respect to any matter, suit, claim, action or proceeding arising with respect to any transaction contemplated by any such agreement, including the defense, settlement or compromise of any claim, action or proceeding for which Parent or Merger Sub may be entitled to indemnification and the Stockholder Representative agrees to act as, and to undertake the duties and responsibilities of, such agent and attorney-in-fact. This power of attorney is coupled with an interest and is irrevocable. The Stockholder Representative, in connection with its obligations under this Agreement, shall not be liable for any action taken or not taken or suffered by it in reliance upon any notice, direction, instruction, consent, statement or other document believed by it to be genuine and duly authorized, nor for any other action or inaction in the absence of his or her own gross negligence or willful misconduct. In all questions arising under this Agreement, the Stockholder Representative may rely on the advice or opinion of counsel, and for anything done, omitted or suffered in good faith by the Stockholder Representative based on such advice, the Stockholder Representative shall not be liable to any Participating Stockholder in its capacity as such. The Stockholder Representative shall have no duties or responsibilities other than those expressly set forth in this Agreement or the Escrow Agreement and the implied duty of good faith and fair dealing. The Stockholder Representative, acting as such under this Agreement, is not charged with knowledge of or any duties or responsibilities under, and shall not be bound by, any other document or agreement, other than the Escrow Agreement. If the Stockholder Representative shall be unable or unwilling to serve in such capacity, his or her successor shall be named by those persons who held a majority of the shares of Company Common Stock, on an as-if converted basis, held by all Participating Stockholders immediately prior to the Effective Time and such successor shall serve and exercise the powers of Stockholder Representative hereunder.

2.1 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any of the following securities:

(a) Conversion of Series C Preferred Stock. Each share of Series C Preferred Stock, par value $0.001 per share, of the Company (“Company Series C Preferred Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of Company Series C Preferred Stock to be cancelled pursuant to Section 2.1(e)), shall be converted, subject to Section 2.2(e), into the right to receive a number of shares of common stock, par value $0.001 per share, of Parent (“Parent Common Stock”) equal to the sum of (i) the Series C Preference Exchange Ratio plus (ii) the Common Exchange Ratio. All such shares of Company Series C Preferred Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent the right to receive a certificate representing the shares of Parent Common Stock into which such Company Series C Preferred Stock was converted in the Merger. Certificates previously representing shares of Company Series C Preferred Stock shall be exchanged for certificates representing whole shares of Parent Common Stock and a check for any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor upon the surrender of such certificates in accordance with the provisions of Section 2.2.

(b) Conversion of Series B Preferred Stock. Each share of Series B preferred stock, par value $0.001 per share, of the Company (“Company Series B Preferred Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of the Company Series B Preferred stock to be cancelled pursuant to Section 2.1(e)), shall be converted, subject to Section 2.2(e), into the right to receive a number of shares of Parent Common Stock equal to the sum of (i) the Series B Preference Exchange Ratio plus (ii) the Common Exchange Ratio. All such shares of Company Series B Preferred Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent the right to receive a certificate representing the shares of Parent Common Stock into which such Company Series B Preferred Stock was

converted in the Merger. Certificates previously representing shares of Company Series B Preferred Stock shall be exchanged for certificates representing whole shares of Parent Common Stock and a check for any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor upon the surrender of such certificates in accordance with the provisions of Section 2.2.

(c) Conversion of Series A Preferred Stock. Each share of Series A preferred stock, par value $0.001 per share, of the Company (“Company Series A Preferred Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of Company Series A Preferred Stock to be cancelled pursuant to Section 2.1(e)), shall be converted, subject to Section 2.2(e), into the right to receive a number of shares of Parent Common Stock equal to the sum of (i) the Series A Preference Exchange Ratio plus (ii) the Common Exchange Ratio. All such shares of Company Series A Preferred Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent the right to receive a certificate representing the shares of Parent Common Stock into which such Company Series A Preferred Stock was converted in the Merger. Certificates previously representing shares of Company Series A Preferred Stock shall be exchanged for certificates representing whole shares of Parent Common Stock and a check for any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor upon the surrender of such certificates in accordance with the provisions of Section 2.2.

(d) Conversion of Company Common Stock. Each share of common stock, par value $.0001 per share, of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of Company Common Stock to be canceled pursuant to Section 2.1(e)), shall be converted, subject to Section 2.2(e), into the right to receive a number of shares of Parent Common Stock equal to the Common Exchange Ratio.

(e) Cancellation of Certain Shares. Each share of Company Common Stock or Company Preferred Stock held by Parent, Merger Sub, any wholly-owned subsidiary of Parent or Merger Sub, in the treasury of the Company or by any wholly-owned subsidiary of the Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no payment shall be made with respect thereto.

(f) Merger Sub. Each share of common stock, par value $0.001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and be exchanged for one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

(g) Change in Shares. The parties acknowledge and agree that the Exchange Ratios assume that no Reverse Stock Split has occurred following the date of this Agreement and prior to the Effective Time. If between the date of this Agreement and the Effective Time the outstanding shares of Parent Common Stock, Company Preferred Stock or Company Common Stock shall have been changed (including as a result of the Reverse Stock Split) into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Exchange Ratios shall be correspondingly adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares.

2.2 Exchange of Certificates.

(a) Exchange Agent. At the Effective Time, Parent shall irrevocably deposit, or shall cause to be deposited, with Mellon Investor Services LLC (the “Exchange Agent”), for the benefit of the holders of

shares of Company Common Stock and Company Preferred Stock, for exchange in accordance with this Article II, through the Exchange Agent, certificates representing the shares of Parent Common Stock issuable pursuant to Section 2.1 and cash in an amount sufficient to permit payment of cash in lieu of fractional shares pursuant to Section 2.2(e) (such certificates for shares of Parent Common Stock, together with cash in lieu of fractional shares and any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”) in exchange for all outstanding shares of Company Common Stock and Company Preferred Stock and all Company Warrants. The Exchange Agent shall, pursuant to irrevocable instructions and subject to Section 1.7, deliver Parent Common Stock contemplated to be issued pursuant to Section 2.1 and the cash contemplated to be issued pursuant to Section 2.2(e) out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time, Parent shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock or Company Preferred Stock (the “Certificates”) (A) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall be in reasonable and customary form) and (B) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Company Common Stock or Company Preferred Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, properly completed and duly executed, and such other documents as may be reasonably required pursuant to such instructions, the holder of such Certificate, subject to Section 1.7, shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Parent Common Stock which such holder has the right to receive in respect of the shares of Company Common Stock or Company Preferred Stock formerly represented by such Certificate (after taking into account all shares of Company Common Stock and Company Preferred Stock then held by such holder), cash in lieu of fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c), and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on any cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Common Stock or Company Preferred Stock which is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Parent Common Stock may be issued to a transferee if the Certificate representing such shares of Company Common Stock or Company Preferred Stock is presented to the Exchange Agent, accompanied by all documents reasonably required to evidence and effect such transfer and by evidence reasonably satisfactory that any applicable stock transfer taxes, if any, have been paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of Parent Common Stock, cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c).

(c) Distributions with Respect to Unexchanged Shares of Company Common Stock or Company Preferred Stock. No dividends or other distributions declared or made after the Effective Time with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e), unless and until the holder of such Certificate shall surrender such Certificate. Subject to the effect of escheat, tax or other applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (A) promptly, the amount of any cash payable with respect to a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (B) at the appropriate payment date, the amount of dividends or other

distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole shares of Parent Common Stock.

(d) Further Rights in Company Common Stock or Company Preferred Stock. All shares of Parent Common Stock issued upon conversion of the shares of Company Common Stock or Company Preferred Stock in accordance with the terms hereof (including any cash paid pursuant to Section 2.2(c) or Section 2.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock or Company Preferred Stock, as applicable.

(e) Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share and such fractional share interests will not entitle the owner thereof to any rights of a stockholder of Parent. In lieu of any fractional shares of Parent Common Stock that would otherwise be issued, each stockholder that would have been entitled to receive a fractional share of Parent Common Stock shall, upon proper surrender of the Certificates, receive a cash payment equal to such fraction multiplied by the Parent Common Stock Price.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock or Company Preferred Stock for twenty-four (24) months after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Common Stock or Company Preferred Stock who have not theretofore complied with this Article II shall thereafter look only to Parent for the shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock to which they are entitled pursuant to Section 2.2(e) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant to Section 2.2(c), in each case, without any interest thereon.

(g) No Liability. None of the Company, the Surviving Corporation or Parent shall be liable to any holder of shares of Company Common Stock or the Company Preferred Stock for any such shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Parent, the execution of an indemnity agreement against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.2(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.2(c), in each case, without any interest thereon.

(i) Withholding. Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock or Company Preferred Stock such amounts as Parent or the Exchange Agent are required to deduct and withhold under applicable Law with respect to the making of such payment. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock or Company Preferred Stock in respect of whom such deduction and withholding was made by Parent or the Exchange Agent.

2.3 Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock and Company Preferred Stock outstanding immediately prior to the Effective Time and held by a stockholder who has not voted in favor of the Merger or consented thereto in writing and who has properly demanded appraisal for such shares in accordance with Delaware Law (“Appraisal Shares”) shall not be converted into a right to receive shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.2(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.2(c), unless such stockholder fails to

perfect or withdraws or otherwise loses such stockholder’s right to appraisal. If, after the Effective Time such stockholder fails to perfect or withdraws or loses such stockholder’s right to appraisal, such shares of Company Common Stock or Company Preferred Stock shall be treated as if they had been converted as of the Effective Time into the right to receive such consideration. The Company shall give Parent prompt notice of any demands received by the Company for appraisal of shares of Company Common Stock and Company Preferred Stock. The Company shall not settle, make any payments with respect to, or offer to settle, any claim with respect to dissenting shares without the consent of Parent.

2.4 Retention Bonus Plan. At the Closing, the Total Merger Consideration shall reduced by the aggregate number of shares of Parent Common Stock payable to participants under terms of the Retention Bonus Plan (the “Retention Bonus Plan Payment”), which in the aggregate shall not exceed six and one-half percent (6.5%) of the Total Merger Consideration. The amount of Retention Bonus Plan Payment for each holder of Participating Units shall be set forth on Schedule 2.4, which shall be delivered by the Company to Parent within two (2) business days of the determination of the Parent Common Stock Price. To the extent there are any changes, an updated Schedule 2.4 shall be delivered by the Company to Parent on the Closing Date. Subject to Section 1.7, at the Effective Time and in addition to the shares of Parent Common Stock issued upon conversion of the shares of Company Common Stock or Company Preferred Stock in accordance with the terms hereof, Parent shall issue to the holders of Participating Units the corresponding number of Parent Common Stock set forth on Schedule 2.4.

2.5 Stock Options. At the Effective Time, all unexercised and unexpired options to purchase Company Common Stock (“Company Options”) then outstanding, under any stock option plan of the Company or any other plan, agreement or arrangement (the “Company Stock Option Plans”), whether or not then exercisable, will be cancelled.

2.6 Company Series C Preferred Stock Warrants. At the Effective Time, each warrant to purchase shares of Company Series C Preferred Stock (“Company Warrants”) which is outstanding immediately prior thereto shall, in accordance with the terms thereof, cease to represent a right to acquire shares of Company Series C Preferred Stock and automatically shall be converted, at the Effective Time, without any action on the part of the holder thereof, into a warrant to purchase Parent Common Stock (as so converted, a “Company Converted Warrant”). Each Company Converted Warrant shall continue to have, and be subject to, the same terms and conditions as set forth in any agreements thereunder immediately prior to the Effective Time, except that, as of the Effective Time, (i) each Company Converted Warrant shall be exercisable (or shall become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares that were issuable upon exercise of such Preferred Warrant immediately prior to the Effective Time multiplied by the sum of (a) the Series C Preference Exchange Ratio plus (b) the Common Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock, and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such Company Converted Warrant shall be equal to the quotient determined by dividing the exercise price per share of Company Preferred Stock at which such Company Warrants was exercisable immediately prior to the Effective Time by the sum of (a) the Series C Preference Exchange Ratio plus (b) the Common Exchange Ratio, rounded up to the nearest whole cent.

2.7 Restricted Stock. If any shares of Company Common Stock, Company Preferred Stock or Parent Common Stock that are outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition providing that such shares may be forfeited or repurchased upon any termination of the stockholders’ employment, directorship or other relationship with the Company or Parent, as the case may be (and/or any Subsidiary of the Company or Parent), under the terms of any agreement with the Company or Parent (and/or any Subsidiary of the Company or Parent), as applicable, that does not by its terms provide that such repurchase option, risk of forfeiture or other condition lapses upon consummation of the Merger, then (i) with respect to such shares of Company Common Stock or Company Preferred Stock, the shares of Parent Common Stock issued upon the conversion of such shares in the Merger will continue to be unvested and subject to the same repurchase options, risks of forfeiture or other conditions following the Effective Time, and the certificates representing such shares of Parent Common Stock may accordingly be marked with

appropriate legends noting such repurchase options, risks of forfeiture or other conditions and (ii) with respect to such shares of Parent Common Stock, such shares will continue to be unvested and subject to the same repurchase options, risks of forfeiture or other conditions following the Effective Time.

3.1 Organization and Qualification; Subsidiaries. Parent is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware.

Parent and each of its Subsidiaries is duly qualified or licensed to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification, licensing or good standing necessary, except for such failures to be so qualified, licensed or in good standing that would not, individually or in the aggregate, have a Material Adverse Effect. Section 3.1 of Parent Disclosure Schedule sets forth a true and complete list of all of the Subsidiaries of Parent. Except as set forth in Section 3.1 of Parent Disclosure Schedule, none of Parent or any of its Subsidiaries holds an Equity Interest in any other person.

3.6 Permits; Compliance With Law. Parent and each of its Subsidiaries is in possession of all authorizations, licenses, permits, certificates, approvals and clearances of any Governmental Entity (collectively, “Parent Permits”), including all Parent Permits under the Federal Food, Drug and Cosmetic Act of 1938, as amended (the “FDCA”) and the regulations of the Federal Food and Drug Administration (the “FDA”) promulgated thereunder, necessary for it to own, lease or operate its properties and other assets and to carry on its business and operations as presently conducted, and all such Parent Permits are valid, and in full force and effect, except where the failure to have, or the suspension or cancellation of, or failure to be valid or in full force and effect of, any of Parent Permits would not, individually or in the aggregate, have a Material Adverse Effect.

Neither Parent, nor to the knowledge of Parent, or any other person or entity, has any express or implied commitment, whether legally enforceable or not, to establish, modify, change or terminate any Parent Benefit Plan, other than with respect to a modification, change or termination required by ERISA or the Code. With respect to each Parent Benefit Plan, Parent has delivered or made available to the Company true, correct and complete copies of (A) each Parent Benefit Plan (or, if not written a written summary of its material terms), including without limitation all plan documents, adoption agreements, trust agreements, insurance contracts or other funding vehicles and all amendments thereto, (B) all summaries and summary plan descriptions, including any summary of material modifications, (C) the annual reports (Form 5500 series) for the three most recent years filed or required to be filed with the IRS with respect to such Parent Benefit Plan (and, if any such annual report is a Form 5500R, the Form 5500C filed with respect to such Parent Benefit Plan), (D) the most recent actuarial report or other financial statement relating to such Parent Benefit Plan, (E) the most recent determination or opinion letter, if any, issued by the IRS with respect to any Parent Benefit Plan and any pending request for such a determination letter, (F) the most recent nondiscrimination tests performed under the Code (including 401(k) and 401(m) tests) for each Parent Benefit Plan, and (G) all filings made with any Governmental Entity, including but not limited any filings under the Voluntary Compliance Resolution or Closing Agreement Program or the Department of Labor Delinquent Filer Program.

With respect to Parent Benefit Plans, no event has occurred and, to the knowledge of Parent, there exists no condition or set of circumstances in connection with which Parent could be subject to any material liability (other than for routine benefit liabilities) under the terms of, or with respect to, such Parent Benefit Plans, ERISA, the Code or any other applicable Law.

(c) Except as disclosed in Section 3.10(c) of Parent Disclosure Schedule: (A) each Parent Benefit Plan which is intended to qualify under Section 401(a), Section 401(k), Section 401(m) or Section 4975(e)(6) of the Code has either received a favorable determination letter from the IRS as to its qualified status or the remedial amendment period for such Parent Benefit Plan has not yet expired, and each trust established in connection with any Parent Benefit Plan which is intended to be exempt from federal income taxation under Section 501(a) of the Code is so exempt, and to Parent’s knowledge no fact or event has occurred that has adversely affected or could adversely affect the qualified status of any such Parent Benefit Plan or the exempt status of any such trust, (B) to Parent’s knowledge there has been no prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code and other than a transaction that is exempt under a statutory or administrative exemption) with respect to any Parent Benefit Plan that could result in material liability to Parent or an ERISA Affiliate, (C) each Parent Benefit Plan can be amended, terminated or otherwise discontinued after the Effective Time in accordance with its terms, without liability (other than (i) liability for ordinary administrative expenses typically incurred in a termination event or (ii) if Parent Benefit Plan is a pension benefit plan subject to Part 2 of Title I of ERISA, liability for the accrued benefits as of the date of such termination (if and to the extent required by ERISA) to the extent that either there are sufficient assets set aside in a trust or insurance contract to satisfy such liability or such liability is reflected on the most recent consolidated balance sheet filed or incorporated by reference in Parent SEC Filings prior to the date of this Agreement), (D) no suit, administrative proceeding, action or other litigation has been brought, or to the knowledge of Parent is threatened, against or with respect to any such Parent Benefit Plan, including any audit or inquiry by the IRS or United States Department of Labor (other than routine benefits claims), (E) no Parent Benefit Plan is a multiemployer pension plan (as defined in

Section 3(37) of ERISA) (“Multiemployer Plan”) or other pension plan subject to Title IV of ERISA and none of Parent or any ERISA Affiliate has sponsored or contributed to or been required to contribute to a Multiemployer Plan or other pension plan subject to Title IV of ERISA, (F) no material liability under Title IV of ERISA has been incurred by Parent or any ERISA Affiliate that has not been satisfied in full, and no condition exists that presents a material risk to Parent or any ERISA Affiliate of incurring or being subject (whether primarily, jointly or secondarily) to a material liability thereunder, (G) none of the assets of Parent or any ERISA Affiliate is, or may reasonably be expected to become, the subject of any lien arising under ERISA or Section 412(n) of the Code, (H) neither Parent nor any ERISA Affiliate has any liability under ERISA Section 502, (I) all tax, annual reporting and other governmental filings required by ERISA and the Code have been timely filed with the appropriate Governmental Entity and all notices and disclosures have been timely provided to participants, (J) all contributions and payments to such Parent Benefit Plan are deductible under Code sections 162 or 404, (K) no amount is subject to Tax as unrelated business taxable income under Section 511 of the Code, and (L) no excise tax could be imposed upon Parent under Chapter 43 of the Code.

(e) Except as required by Law, no Parent Benefit Plan provides any of the following retiree or post-employment benefits to any person: medical, disability or life insurance benefits.

(a) Parent and each of its Subsidiaries is in material compliance with all applicable Laws respecting labor, employment, fair employment practices, terms and conditions of employment, workers’ compensation, occupational safety, plant closings, and wages and hours. None of Parent or any of its Subsidiaries is a party to any collective bargaining or other labor union contract applicable to persons employed by Parent or any of its Subsidiaries, and no collective bargaining agreement or other labor union

contract is being negotiated by Parent or any of its Subsidiaries. There is no labor dispute, strike, slowdown or work stoppage against Parent or any of its Subsidiaries pending or, to the knowledge of Parent, threatened which may interfere in any respect that would have a Material Adverse Effect with the respective business activities of Parent or any of its Subsidiaries. To Parent’s knowledge, no employee of Parent or any of its Subsidiaries is in any material respect in violation of any term of any employment contract, non-disclosure agreement, non-competition agreement, or any restrictive covenant to a former employer relating to the right of any such employee to be employed by Parent or such Subsidiary because of the nature of the business conducted or presently proposed to be conducted by it or to the use of trade secrets or proprietary information of others.

Except as set forth in Section 3.11(b) of Parent Disclosure Schedule, none of the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby will (either alone or in conjunction with any other event, such as termination of employment) (A) result in any payment (including, without limitation, severance, unemployment compensation, parachute or otherwise) becoming due to any director or any employee of Parent or any of its Subsidiaries or affiliates from Parent or any of its Subsidiaries or affiliates under any Parent Benefit Plan or otherwise, (B) significantly increase any benefits otherwise payable under any Parent Benefit Plan or (C) result in any acceleration of the time of payment or vesting of any material benefits.

3.12 Tax Treatment. None of Parent, any of its Subsidiaries or any of Parent’s affiliates has taken, has agreed to take, or will take any action that would prevent the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code. Parent is not aware of any agreement, plan or other circumstance that would prevent the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

3.13 Contracts. As of the date hereof, except as filed as exhibits to Parent SEC Filings or as disclosed in Section 3.13 of Parent Disclosure Schedule, none of Parent or any of its Subsidiaries is a party to or bound by any Contract that (1) is a “material contract” (as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC), (2) contains any non-compete or exclusivity provisions with respect to any line of business or geographic area with respect to Parent or any of its Subsidiaries, or which restricts the conduct of any line of business by Parent or any of its Subsidiaries or any geographic area in which Parent or any of its Subsidiaries may conduct business, in each case in any material respect or (3) which would prohibit or materially delay the consummation of the Merger or any of the transactions contemplated by this Agreement.

As of the date hereof, none of Parent or any of its Subsidiaries has received any written notice of any violation or default under (or any condition which with the passage of time or the giving of notice would cause such a violation of or default under) any Parent Material Contract.

Without limiting the foregoing, the parties agree that any violation of the restrictions set forth in this Section 5.6(a) by any Representative of Parent or the Company or any of its respective Subsidiaries, whether or not such person is purporting to act on behalf of such party, shall constitute a breach of this Section 5.6(a). For purposes of this Agreement, a Representative shall be deemed to have breached this Section 5.6(a) if such Representative takes any action that would constitute a breach by Parent or the Company of this Section 5.6(a) were such party to take such action directly. Parent and the Company shall immediately terminate, and shall cause its Subsidiaries and its and its Subsidiaries’ Representatives to immediately terminate, all discussions or negotiations, if any, with any third party with respect to, or any that could reasonably be expected to lead to or contemplate the possibility of, an Acquisition Proposal or Acquisition Inquiry.

approval of its stockholders as contemplated by Section 5.4 if, (x) Parent or the Company, as the case may be, has complied with its obligations under this Section 5.6, (y) Parent Board or the Company Board, as applicable, reasonably determines in good faith, after having taken into account the advice of its nationally recognized outside legal counsel (which may be its current outside legal counsel), that failure to take such actions would constitute a breach of its fiduciary duties to the its stockholders under applicable Law and (z) prior to taking such actions, Parent Board or the Company Board, as applicable, shall have given the other party, at least five days notice of its intention to take such action and the opportunity during such period to submit a competing proposal (which shall be considered by Parent Board or Company Board, as applicable, in good faith, after consultation with nationally recognized outside legal counsel (which may be its current outside legal counsel) and financial advisor (which may be its current outside financial advisor)) and, notwithstanding such competing proposal, the Superior Proposal continues to constitutes a Superior Proposal. Neither the Parent Board’s ability to take any of the actions described in this Section 5.6(b) nor the commencement, disclosure, announcement or submission to it of an Acquisition Proposal shall relieve Parent’s obligation to duly call, give notice of, convene and hold the Parent Stockholders’ Meeting to consider and vote upon the issuance by Parent of the shares of Parent Common Stock issuable pursuant to this Agreement and the change-of-control of Parent in connection with the transactions contemplated by this Agreement, pursuant to Section 5.4(b). Neither the Company Board’s ability to take any of the actions described in this Section 5.6(b) nor the commencement, disclosure, announcement or submission to it of an Acquisition Proposal shall relieve the Company’s obligation to duly call, given notice of, convene and hold the Company Stockholders’ Meeting to adopt this Agreement, pursuant to Section 5.4(b).

(c) In addition to the obligations set forth in Section 5.6(a), Parent or the Company, as applicable, shall as promptly as practicable (and in any event within 24 hours) advise the other of any Acquisition Inquiry or Acquisition Proposal, including the identity of the person making such Acquisition Proposal or Acquisition Inquiry and the terms and conditions thereof, and such party shall, within 24 hours of the receipt thereof, promptly provide to the other party copies of any written materials received in connection with any of the foregoing. Such Party shall keep the other party fully informed of the status and material details (including amendments or proposed amendments) of any such Acquisition Proposal or Acquisition Inquiry and keep the other party fully informed as to the material details of any nonpublic information requested of it and as to the details of all discussions or negotiations with respect to any such Acquisition Proposal or Acquisition Inquiry, and shall provide to the other party within 24 hours of receipt thereof all written materials received by it with respect thereto. Parent or the Company, as applicable, shall promptly provide to the other party any non-public information concerning it provided to any other person in connection with any Acquisition Proposal or Acquisition Inquiry, which was not previously provided to the other party.

(d) Parent and the Company agree not to release or permit the release of any person from, or to waive or permit the waiver of any provision of, any confidentiality, non-solicitation, no hire, “standstill” or similar Contract to which Parent or the Company or any of its Subsidiaries is a party or under which Parent or the Company or any of its Subsidiaries has any rights, and will use its commercially reasonable efforts to cause each such agreement to be enforced at the request of the other party.

Parent and the Company shall use commercially reasonable best efforts to furnish to each other all information required for any application or other filing under the rules and regulations of any applicable Law (including all information required to be included in the Joint Proxy Statement/Prospectus and the Registration Statement) in connection with the transactions contemplated by this Agreement.

(b) Parent and the Company shall give (or shall cause their respective Subsidiaries to give) any notices to third parties, and use, and cause their respective Subsidiaries to use, all commercially reasonable best efforts to obtain any third party consents, (A) necessary, proper or advisable to consummate the transactions contemplated in this Agreement, (B) required to be disclosed in Parent Disclosure Schedule or the Company Disclosure Schedule, as applicable, or (C) required to prevent a Material Adverse Effect with respect to Parent or the Company from occurring prior to or after the Effective Time.

The press release announcing the execution of this Agreement shall be issued in the form as has been mutually agreed upon by Parent and the Company and each of Parent and the Company shall consult with, and obtain the consent of, the other party (which shall not be unreasonably withheld or delayed) before issuing any other press release or otherwise making any public statement with respect to the Merger or this Agreement and shall not issue any such press release or make any such public statement prior to consulting with and obtaining the prior consent of the other party (which shall not be unreasonably withheld or delayed); provided, that a party may, without consulting with or obtaining the prior consent of the other party, issue such press release or make such public statement as may be required by applicable Law or, in the case of Parent, by any listing agreement with a national securities exchange or automated quotation system to which it is a party, if such party has used commercially reasonable best efforts to consult with the other party and to obtain such other party’s consent, but has been unable to do so in a timely manner. Notwithstanding the provisions of this Section 5.9, in the event that there has been a change of recommendation pursuant to Section 5.6, neither Parent nor the Company will have any further obligation to consult with each other, and agree, before issuing any press release or otherwise making any public statement with respect to the Merger, this Agreement or any Acquisition Proposal.

Parent shall promptly prepare and submit to The NASDAQ Stock Market, Inc. a listing application covering the shares of Parent Common Stock to be issued in the Merger and shall use its reasonable best efforts to cause such shares to be approved for listing on The NASDAQ National Market, including, without limitation, effecting a reverse stock split if necessary with respect to the then-outstanding shares of Parent Common Stock, such that each share of Parent Common Stock shall be converted into such lesser number of shares of Parent Common Stock according to a ratio between (and including) 5 into 1 and 2 into 1 (the “Reverse Stock Split”), subject to official notice of issuance, prior to the Effective Time. The Company shall furnish such information concerning it, the Company’s director nominees pursuant to Section 1.6 hereof and the holders of the Company’s capital stock as Parent may reasonably request in connection with such actions and the preparation of the listing application.

5.11 Employee Benefit and Section 16 Matters.

(a) Prior to the Effective Time, Parent Board and Company Board, or an appropriate committee of non-employee directors, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the acquisition by any officer or director of the Company who may become a covered person of Parent for purposes of Section 16 of the Exchange Act and the rules and regulations thereunder (“Section 16”) of shares of Parent Common Stock or options to acquire Parent Common Stock pursuant to this Agreement and the Merger shall be an exempt transaction for purposes of Section 16.

(b) Following the Closing, Parent shall provide similarly situated employees of Parent who were employees of Parent as of the Effective Time and employees of Parent (or any Subsidiary, including the Surviving Corporation) who were employees of the Company or any Subsidiary of the Company prior to the Effective Time with substantially similar compensation and benefits in the aggregate.

(c) Employees of the Company or any Subsidiary of the Company who become employees of Parent or a Subsidiary of Parent at or after the Effective Time (“Continuing Employees”) shall receive credit for purposes of eligibility to participate (but not benefit accruals) under Parent Benefit Plans for service accrued or deemed accrued prior to the Effective Time with the Company or any Subsidiary; provided, however, that such crediting of service shall not operate to duplicate any benefit or the funding of any benefit. In addition, to the extent permitted by applicable insurance policies, Parent shall waive, or cause to be waived, under Parent Benefit Plans any limitations on benefits relating to any pre-existing conditions of Continuing Employees, and Parent shall recognize, or cause to be recognized under Parent Benefit Plans, for purposes of applying annual deductibles, co-payments and out-of-pocket maximums, amounts paid by Continuing Employees in the calendar year in which the Effective Time occurs under Company Benefit Plans as though such amounts had been paid in accordance with the terms and conditions of Parent Benefit Plans in such calendar year.

(d) The parties hereto acknowledge and agree that all provisions contained in this Section 5.11 with respect to employees are included for the sole benefit of the respective parties hereto and shall not create any right (i) in any other person, including, without limitation, any employees, former employees, any participant in any Company Benefit Plan or Parent Benefit Plan or any beneficiary thereof or (ii) to continued employment with Parent or the Company. After the Effective Time, nothing contained in this Section 5.11 shall interfere with Parent’s right to amend, modify or terminate any Company Benefit Plan or Parent Benefit Plan or to terminate the employment of any employee of Parent or the Company for any reason.

5.12 Indemnification of Directors and Officers.

(a) The Company, Merger Sub and Parent agree that the indemnification obligations set forth in the Company Certificate and Company By-laws existing in favor of those persons who are directors and officers of the Company as of the date of this Agreement for their acts and omissions as directors and officers thereof prior to the Effective Time, shall survive the Merger and be observed by Parent and Merger Sub to the fullest extent permitted by Delaware Law for a period of six years from the date on which the Merger becomes effective.

(b) For six years from the Effective Time, Parent shall provide to the Company’s directors and officers, as of the date of this Agreement, an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time (the “D&O Insurance”) that is no less favorable than the Company’s existing policies (true and complete copies which have been previously provided or made available to Parent) or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that Parent shall not be required to pay an annual premium for the D&O Insurance with respect to the Company in excess of 300% of the last annual premium paid by the Company prior to the date of this Agreement for D&O Insurance with respect to the Company, which last annual premium the Company represents and warrants to be approximately $27,200. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid policies have been obtained prior to the Effective Time for purposes of this Section 5.12, which policies provide such directors and officers with coverage for an aggregate period of six years with respect to claims arising from facts or events that occurred on or before the Effective Time, including, without limitation, in respect of the transactions contemplated by this Agreement. If such prepaid policies have been obtained prior to the Effective Time, Parent shall maintain such policies in full force and effect, and continue to honor the obligations thereunder.

5.14 FDA Meetings. The Company agrees that between the date of this Agreement and the Effective Time the Company will use reasonable efforts to provide Parent and its representatives with a reasonable opportunity to review and confer with Company regarding any filing, correspondence, or other communications proposed to be submitted or transmitted to the FDA and to attend and participate in any meetings with any representatives of the FDA.

5.15 Minimum Cash Balance.

(a) Parent shall have a minimum Cash balance after the payment of all Expenses (the “Parent Minimum Cash Balance”) on the Closing Date of (i) $78,000,000, if the Closing occurs on or before, November 30, 2005 or (ii) 78,000,000 less an amount not more than $3,000,000 per month after November 30, 2005, if the Closing occurs after November 30, 2005.

(b) Parent Termination Fee. Parent shall pay to the Company a termination fee (the “Parent Termination Fee”) of $3,000,000 as liquidated damages in the event that this Agreement is terminated as follows: (i) if the Company shall terminate this Agreement pursuant to Section 7.1(d); or (ii) if (A) either party shall terminate this Agreement pursuant to Section 7.1(b) or Section 7.1(g)(i) and, at any time after the date of this Agreement and before the termination of this Agreement, an Acquisition Proposal with respect to Parent shall have been publicly made, proposed or communicated and not bona fide withdrawn and (B) within twelve months following the termination of this Agreement, Parent consummates any Acquisition Proposal or enters into an agreement, understanding (including a letter of intent) with respect to any Acquisition Proposal which is subsequently consummated. Any Parent Termination Fee payable under this provision shall be payable as liquidated damages to compensate the Company for the damages the Company will suffer if this Agreement is terminated in the circumstances set forth in this Section 7.2(b), which damages cannot be determined with reasonable certainty. It is specifically agreed that any Parent Termination Fee to be paid pursuant to this Section 7.2(b) represents liquidated damages and not a penalty.

(c) Company Termination Fee. The Company shall pay to Parent a termination fee (the “Company Termination Fee”) of $3,000,000 as liquidated damages in the event that this Agreement is terminated as follows: (i) if Parent shall terminate this Agreement pursuant to Section 7.1(d); or (ii) if (A) either party shall terminate this Agreement pursuant to Section 7.1(b) or Section 7.1(g)(ii) and, at any time after the date of this Agreement and before the termination of this Agreement, an Acquisition Proposal with respect to The Company shall have been made, proposed or communicated and not withdrawn and (B) within twelve months following the termination of this Agreement, the Company consummates any Acquisition Proposal or enters into an agreement, understanding (including a letter of intent) with respect to any Acquisition Proposal which is subsequently consummated.

It is specifically agreed that any Company Termination Fee to be paid pursuant to this Section 7.2(c) represents liquidated damages and not a penalty.

(d) All Payments. Any payment required to be made pursuant to Section 7.2(b)(i) or 7.2(c)(i) shall be made not later than two business days after the date of termination.

In no event shall more than one Parent Termination Fee or Company Termination Fee be made. In no event shall Parent be required to pay Parent Termination Fee nor shall The Company be required to pay the Company Termination Fee if, immediately prior to the termination of this Agreement, the entity otherwise entitled to receive such fee was in material breach of its obligations under this Agreement. All payments under Section 7.2 shall be made by wire transfer of immediately available funds to an account designated by the party entitled to receive payment. Parent and the Company acknowledge that the agreements contained in Section 7.2 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, neither Parent nor the Company would enter into this Agreement. Accordingly, if either party fails promptly to pay any amount due pursuant to this Section 7.2 and, in order to obtain such payment, Parent or the Company, as applicable, commences a suit which results in a judgment against the other party for the fee set forth in this Section 7.2,

such defaulting party shall pay to the prevailing party its costs and Expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the fee at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

7.4 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto, (b) waive any inaccuracies in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto, and (c) waive compliance by the other party with any of the agreements or conditions contained herein; provided, however, that after any approval of the transactions contemplated by this Agreement by the stockholders of either party, there may not be, without further approval of such stockholders, any extension or waiver of this Agreement or any portion thereof which, by Law or, in the case of Parent, in accordance with the rules of The NASDAQ National Market, requires further approval by such stockholders. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

7.5 Expenses. All Expenses incurred by the parties hereto shall be borne solely and entirely by the party which has incurred the same.

ARTICLE VIII

SURVIVAL OF REPRESENTATIONS AND WARRANTIES, COVENANTS AND AGREEMENTS

8.1 Survival Periods. If the Merger is consummated, the representations and warranties of the parties contained in this Agreement and the certificates of Parent and the Company delivered pursuant to Section 6.3(a) shall survive the Effective Time, regardless of any investigation or disclosure made by or on behalf of any of the parties to this Agreement for a period of six (6) months following the Closing (the “Indemnity Period”); provided, however, that no right to indemnification pursuant to this Article 8 in respect of any claim based upon any breach of any representation or warranty that is set forth in a Claim Notice delivered prior to the expiration of the Indemnity Period shall be affected by the expiration of such Indemnity Period. If the Merger is consummated, all covenants of the parties (including the covenants set forth in Article IV) shall expire and be of no further force or effect as of the Effective Time, except to the extent such covenants provide that they are to be performed after the Effective Time; provided, however, that no right to indemnification pursuant to Article 8 in respect of any claim based upon any breach of a covenant shall be affected by the expiration of such covenant. The right to indemnification pursuant to Article 8 based on any breach or inaccuracy of such representations, warranties and covenants will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty or covenant; provided, however, that the representations and warranties of the Parent and Company shall be deemed to be limited by the disclosures set forth in the Disclosure Schedules. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant, will not affect any right to indemnification that may otherwise exist based on any breach or inaccuracy of such representations, warranties and covenants. No claim for indemnification may be asserted after the expiration of the Indemnity Period.

8.2 Indemnification.

(a) General. From and after the Closing, Parent and its affiliates, and each of their respective directors, officers, stockholders, employees and agents (collectively, the “Parent Indemnitees”) shall be entitled to be indemnified from the Escrow Fund from and against any and all damages, claims, losses, expenses, costs, taxes, interest, penalties, fines, obligations and liabilities, including liabilities for all reasonable attorneys’, accountants’, and experts’ fees and expenses including those incurred to enforce the terms of this Agreement (collectively, “Damages”), directly or indirectly arising out of or resulting from (without duplication):

(i) any breach or inaccuracy of any representation or warranty made by the Company in this Agreement (without giving effect to any supplement to the Disclosure Schedule), whether as of the date of this Agreement or as of the Closing Date (as though such representation or warranty were made as of the Closing Date rather than the date of this Agreement, except in the case of any representation and warranty which by its terms speaks only as of a specific date or dates);

(ii) any breach or inaccuracy of any certification, representation or warranty made by the Company in the certificate referred to in Section 6.3(a) as of the date such certificate is delivered to Parent;

(iii) the breach by the Company of any of the covenants or agreements made by the Company in this Agreement that are required to be performed by the Company prior to the Closing; or

(iv) (a) any amounts paid by Parent or Merger Sub to former stockholders of the Company with respect to Appraisal Shares required to be paid or otherwise reasonably paid to the extent that the aggregate of such amounts exceed the aggregate portion of the Total Merger Consideration that the holders of such Appraisal Shares would have received in the Merger pursuant to Section 1.7 had they not perfected their appraisal rights, plus (b) that portion of the Escrow Shares deposited pursuant to Article 8 with regard to such holder.

The Company shall have no liability with respect to this Article 8 after the Closing and the Company stockholders will have no right to seek contribution from the Company after the Closing with respect to the indemnification obligations hereunder.

(b) Limitations.

(i) Threshold Amount. Notwithstanding the other provisions of this Article 8, no Parent Indemnitee shall be entitled to be indemnified out of the Escrow Fund with respect to a claim for indemnification under this Article 8 (other than claims for indemnification made pursuant to Sections 8.2(a)(iv)) unless and until the aggregate amount that the Parent Indemnitees are otherwise entitled to recover out of the Escrow Fund in the absence of this clause (not including recoveries for claims for indemnification made pursuant to Section 8.2(a)(iv)) exceeds $400,000. At such time that the aggregate amount recoverable by Parent Indemnitees from the Escrow Fund (in the aggregate) in the absence of this clause (not including recoveries for claims for indemnification made pursuant to Section 8.2(a)(iv)) exceeds $400,000, the Parent Indemnitees shall be entitled to recover from the Escrow Fund the aggregate amount in excess of the first $1.00 of such amount otherwise recoverable by Parent.

(ii) Exclusivity of Escrow Fund. Notwithstanding anything to the contrary set forth in this Agreement, recovery from the Escrow Fund shall be the sole and exclusive remedy of any Parent Indemnitee with respect to any right to indemnification hereunder or other claims arising after the Closing with respect to the Merger or otherwise arising under or with respect to this Agreement.

(iii) Fraud. Notwithstanding any other provision herein, there shall be no time limit or monetary limit on claims for Damages arising by operation of law (and not under the express terms of this Agreement) against any Person arising from such Person’s fraud.

(iv) Escrow Shares. For all purposes under this Article 8, the Escrow Shares shall be valued at the Parent Common Stock Price.

8.3 Indemnification Procedures.

(a) General. If any Parent Indemnitee desires to seek indemnification under Section 8.2, the Parent Indemnitee shall give written notice to the Stockholder Representative (a “Claim Notice”) prior to the expiration of the Indemnity Period, which written notice shall describe in reasonable detail the nature of the claim and the amount of the Damages incurred (the “Claimed Amount”). The Stockholder Representative may respond to any Claim Notice (a “Claim Response”) within 30 days after the date that the Claim Notice is received by the Stockholder Representative (the “Response Period”). Any Claim Notice or Claim Response shall be given in accordance with the notice requirements hereunder, and any Claim Response shall specify whether or not the claim described in the related Claim Notice or the Claimed Amount is disputed. Notwithstanding anything in this Agreement to the contrary, if the Stockholder Representative fails to give a Claim Response within the Response Period or does not dispute the claim described in a Claim Notice, then the Parent Indemnitee and the Stockholder Representative shall instruct the Escrow Agent to release the Claimed Amount to the Parent Indemnitee from the Escrow Fund. Notwithstanding the provisions herein, the failure of any Parent Indemnitee to give notice as provided in this Section 8.3 shall not prejudice the rights of such Parent Indemnitee under this Section 8.3, except to the extent that there is actually prejudice by such failure to give prompt notice.

(b) Defense of a Third Party Claim. If Parent or the Company receives notice of any claim or action by any third party or any threatened claim or action by any third party that may give rise to an indemnification right of any Parent Indemnitee under this Article 8, then Parent shall promptly (and in any event within ten Business Days) deliver to the Stockholder Representative a written notice describing such claim or action in reasonable detail; provided, however, that for the sole purpose of determining whether a claim or action or a threatened claim or action may give rise to an indemnification right of any Parent Indemnitee within the meaning of this sentence, the limitation set forth in Section 8.2(b)(i) shall not be taken into account. Parent may elect to defend any such third party claim. If Parent elects to defend a third party claim, then, promptly (and in any event within ten Business Days) after receiving notice of such third party claim (or sooner, if the nature of such third party claim so requires), Parent shall notify the Stockholder Representative of its intent to do so, and the Stockholder Representative shall provide Parent reasonable access to any documents in the possession of the Stockholder Representative for use in the defense of such third party claim (and pending such notice and assumption of defense, the Stockholder Representative may take such steps to defend against such third party claim as, in such Stockholder Representative’s good-faith judgment, are appropriate). If Parent elects to control the defense of the claim, the following provisions of this Section 8.3(b) shall apply. The Parent shall use counsel in the defense of such third party claim that is reasonably acceptable to the Stockholder Representative. The parties agree that, without limiting Parent’s choice of counsel, it shall be reasonable for Parent to use counsel that it has used in the past. The Stockholder Representative shall have the right to participate in the defense of the claim at its own expense. The Parent Indemnitee shall keep the Stockholder Representative reasonably informed as to the status of and all material developments in the defense.

(c) Separate Counsel. If Parent does not elect to control the defense of the third party claim, the provisions of this Section 8.3(c) shall govern. The Stockholder Representative may control the defense of the claim (with counsel which shall be reasonably acceptable to the Parent Indemnitee). The Parent Indemnitees shall reasonably cooperate in the defense of such third party claim. After notice from Parent of its election not to assume the defense of a third party claim, no Parent Indemnitee shall be entitled under this Article 8 to be indemnified or reimbursed any legal or other expenses subsequently incurred by any Parent Indemnitee in connection with the defense of such claim.

(d) Settlement. The Stockholder Representative and the Parent Indemnitees shall promptly give to one another notice of any bona fide settlement offers received with respect to any third party claim for which indemnification is sought. Neither the Stockholder Representative nor Parent shall have the right to settle any third party claim or consent to the entry of any judgment with respect thereto without the prior written consent of the other, which consent will not be unreasonably withheld or delayed. Unless the Stockholder Representative shall have agreed in writing that the amount of any settlement or compromise shall be paid out of the Escrow

Fund, the fact that such settlement or compromise has been entered into shall not be determinative of the amount to which any Parent Indemnitee may be entitled to be indemnified or reimbursed out of the Escrow Fund.
