On (or at opening of business on the day following) the Closing Date, a properly executed certificate of merger (the “Certificate of Merger”) conforming to the requirements of the DGCL shall be filed with the Secretary of State of the State of Delaware.

               (b) Conversion of Merger Sub Stock. By virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company, each share of the common stock, par value $0.001 per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation.

If the Merger Consideration shall be insufficient to make payment in full to all holders of Series E Convertible Preferred Stock of the Series E Per Share Liquidation Preference with respect to each share of Series E Convertible Preferred Stock held, then the Merger Consideration shall be distributed among the holders of the Series E Convertible Preferred Stock ratably in proportion to the full amounts to which they would otherwise be respectively entitled.

                    (ii) After payment in full of the Series E Per Share Liquidation Preference as set forth in Section 1.5(d)(i), the holders of each share of the Series D Convertible Preferred Stock shall be entitled to receive, prior and in preference to any distribution of Merger Consideration to the holders of the Series C Convertible Preferred Stock, the Series B Convertible Preferred Stock, the Series A Convertible Preferred Stock or the Company Common Stock, by reason of their ownership thereof, the Per Share Liquidation Preference applicable to each such share of the Series D Convertible Preferred Stock (the “Series D Per Share Liquidation Preference”).

                    (iii) After payment in full of the Series E Per Share Liquidation Preference and the Series D Per Share Liquidation Preference as set forth in Section 1.5(d)(i) and Section 1.5(d)(ii), respectively, the holders of each share of the Series C Convertible Preferred Stock shall be entitled to receive, prior and in preference to any distribution of Merger Consideration to the holders of the Series B Convertible Preferred Stock, the Series A Convertible Preferred Stock or the Company Common Stock, by reason of their ownership thereof, the Per Share Liquidation Preference applicable to each such share of the Series C Convertible Preferred Stock (the “Series C Per Share Liquidation Preference”). If the Merger Consideration shall be insufficient to make payment in full to all holders of Series C Convertible Preferred Stock of the Series C Per Share Liquidation Preference with respect to each share of Series C Convertible Preferred Stock held, then the Merger Consideration shall be distributed among the holders of the Series C Convertible Preferred Stock ratably in proportion to the full amounts to which they would otherwise be respectively entitled.

                    (iv) After payment in full of the Series E Per Share Liquidation Preference, the Series D Per Share Liquidation Preference and the Series C Per Share Liquidation Preference as set forth in Section 1.5(d)(i), Section 1.5(d)(ii), and Section 1.5(d)(iii), respectively, the holders of each share of the Series B Convertible Preferred Stock shall be entitled to receive, prior and in preference to any distribution of Merger Consideration to the holders of the Series A Convertible Preferred Stock or the Company Common Stock, by reason of their ownership thereof, the Per Share Liquidation Preference applicable to each such share of the Series B Convertible Preferred Stock (the “Series B Per Share Liquidation Preference”). If the Merger Consideration shall be insufficient to make payment in full to all holders of Series B Convertible Preferred Stock of the Series B Per Share Liquidation Preference with respect to each share of Series B Convertible Preferred Stock held, then the Merger Consideration shall be distributed among the holders of the Series B Convertible Preferred Stock ratably in proportion to the full amounts to which they would otherwise be respectively entitled.

                    (v) After payment in full of the Series E Per Share Liquidation Preference, the Series D Per Share Liquidation Preference, the Series C Per Share Liquidation Preference and Series B Per Share Liquidation Preference as set forth in Section 1.5(d)(i), Section 1.5(d)(ii), Section 1.5(d)(iii) and Section 1.5(d)(iv), respectively, the holders of each share of the Series A Convertible Preferred Stock shall be entitled to receive, prior and in preference to any distribution of Merger Consideration to the holders of the Company Common Stock, by reason of their ownership thereof, the Per Share Liquidation Preference applicable to each such share of the Series A Convertible Preferred Stock (the “Series A Per Share Liquidation Preference”). If the Merger Consideration shall be insufficient to make payment in full to all holders of Series A Convertible Preferred Stock of the Series A Per Share Liquidation Preference with respect to each share of Series A Convertible Preferred Stock held, then the Merger Consideration shall be distributed among the holders of the Series A Convertible Preferred Stock ratably in proportion to the full amounts to which they would otherwise be respectively entitled.

                    (vi) After payment in full of the aggregate Series E Per Share Liquidation Preference, the Series D Per Share Liquidation Preference, the Series C Per Share Liquidation Preference, Series B Per Share Liquidation Preference and the Series A Per Share Liquidation Preference as set forth Section 1.5(d)(i), Section 1.5(d)(ii), Section 1.5(d)(iii), Section 1.5(d)(iv) and Section 1.5(d)(v), respectively, the entire remaining Merger Consideration, if any, shall be distributed among the holders of the Company Common Stock, the holders of Company Preferred Stock and the holders of Company Options entitled to payments pursuant to Section 1.6 hereof, in proportion to the shares of Company Common Stock held at the Effective Time and the shares of Company Common Stock issuable upon conversion of the shares of Company Preferred Stock held at the Effective Time and the number of shares of Company Common Stock subject to Company Options held at the Effective Time (provided that, for the avoidance of doubt, the exercise price per each share of Company Common Stock subject to a Company Option shall be deducted from any payment of Merger Consideration in respect of such Company Option).

     1.6 Treatment of Stock Options. Immediately prior to the Effective Time, each Company Option that is then outstanding and unexercised, whether or not vested, shall become fully vested immediately prior to the Effective Time. At the Effective Time, each such Company Option shall be converted into the right of the holder thereof to receive for each share of Company Common Stock subject to such Company Option an amount in cash equal to (a) the excess, if any, of: (i) the Residual Upfront Per Share Value; minus (ii) the exercise price per share of Company Common Stock subject to such Company Option; plus (b) any amounts required to be paid by Parent with respect to such share in accordance with the terms of Section 1.7(c)(vii), as and when such payments are required to be made; plus (c) the excess, if any, of: (i) any disbursements of cash to be made from the Escrow Fund and/or the

value (based on the Escrow Average Closing Price (as defined in the Escrow Agreement)) of any shares of Parent Common Stock to be released from the Escrow Fund, in each case with respect to each share of Company Common Stock subject to such Company Option to the former holder thereof in accordance with the terms of the Escrow Agreement, as and when such disbursements or releases are required to be made; minus (ii) the exercise price per share of Company Common Stock subject to such Company Option (less the amount of such exercise price, if any, taken into account in determining the amounts under clauses “(a)” or “(b)” of this sentence, if any). Prior to the Effective Time, the Company shall take all action that may be necessary (under the Company Option Plan or otherwise) to effectuate the provisions of this Section 1.6 and to ensure that, from and after the Effective Time, each holder of an outstanding Company Option converted as provided in this Section 1.6 shall cease to have any rights with respect thereto, except the right to receive the consideration specified in this Section 1.6 without interest.

     1.7 Post-Closing Payments.

          (a) Value Protection Consideration. On or before March 15, 2011, Parent shall: (i) prepare or cause to be prepared a statement (the “Net Product Revenues Statement”) setting forth Parent’s calculation of the Net Product Revenues and any Value Protection Consideration Amount; and (ii) deliver or cause to be delivered such Net Product Revenues Statement to the Stockholders’ Agent for and on behalf of the Eligible Stockholders.

          (b) Objections. In the event that the Stockholders’ Agent objects to Parent’s calculation of the Net Product Revenues or the Value Protection Consideration Amount set forth in the Net Product Revenues Statement or requires further information in order to perform such calculations or determine such amounts, then within 20 days after the delivery to the Stockholders’ Agent of the Net Product Revenues Statement (the “Initial Response Period”), the Stockholders’ Agent shall deliver to Parent a written notice (an “Initial Objection Notice”): (i) describing in reasonable detail the Stockholders’ Agent’s objections to Parent’s calculation of the amounts set forth in the Net Product Revenues Statement and containing a statement setting forth the Net Product Revenues or the Value Protection Consideration Amount determined by the Stockholders’ Agent to be correct; or (ii) requesting additional information from Parent that the Stockholders’ Agent requires in order to perform such calculations or determine such amounts (which information, to the extent reasonably necessary in order to perform such calculations, shall be provided by Parent within 20 days after Parent’s receipt of such request). If the Stockholders’ Agent does not deliver an Initial Objection Notice to Parent during the Initial Response Period, then Parent’s calculation of the amounts set forth in the Net Product Revenues Statement shall be conclusive and binding on Parent, the Eligible Stockholders and the Stockholders’ Agent. If the Stockholders’ Agent delivers an Initial Objection Notice to Parent accompanied by a request for additional information from Parent as described above during the Initial Response Period, then the Stockholders’ Agent shall have an additional 20 days after receiving from Parent all of the information to be provided by Parent (the “Final Response Period”) to deliver to Parent a written notice (a “Final Objection Notice”) describing in reasonable detail the Stockholders’ Agent’s objections to Parent’s calculations of the amounts set forth in the Net Product Revenues Statement and accompanied by a statement setting forth the Net Product Revenues or the Value Protection Consideration Amount determined by the Stockholders’ Agent to be correct. If the Stockholders’ Agent has requested additional information during the Initial Response Period and does not deliver a Final Objection Notice to Parent during the Final Response Period, then Parent’s calculation of the amounts set forth in the Net Product Revenues Statement shall be conclusive and binding on Parent, the Eligible Stockholders and the Stockholders’ Agent. If the Stockholders’ Agent delivers an Initial Objection Notice or Final Objection Notice, as the case may be, accompanied by a statement setting forth the Net Product Revenues or the Value Protection Consideration Amount determined by the Stockholders’ Agent to be correct to Parent during either the Initial Response Period or the Final Response Period in accordance with this Section 1.7(b), and if the Stockholders’ Agent and Parent are unable to agree upon the calculation of the amounts

set forth in the Net Product Revenues Statement within 20 days after such Initial Objection Notice or Final Objection Notice, as the case may be, is delivered to Parent, the dispute shall be finally settled by a “Big Four” accounting firm (other then the firm that audits Parent’s annual financial statements at that time) selected by the Stockholders’ Agent and mutually acceptable to Parent. The determination by the independent accounting firm of the disputed amounts shall be conclusive and binding on Parent, the Eligible Stockholders and the Stockholders’ Agent. The costs and expenses of the independent accounting firm shall be allocated between Parent, on the one hand, and the Stockholders’ Agent (on behalf of the Eligible Stockholders), on the other hand, based upon the proximity of each party’s calculation of the Net Product Revenues as compared to the independent accounting firm’s determination of the Net Product Revenues, with such allocation determined in accordance with the last two sentences of this paragraph. First, the following calculations shall be made: divide: (A) the difference between: (1) the Net Product Revenues as calculated by Parent or the Stockholders’ Agent, as the case may be; and (2) the Net Product Revenues as calculated by the independent accounting firm ; by (B) the Net Product Revenues as calculated by the independent accounting firm. The proportion of costs and expenses (the “Post-Closing Payment Fees”) payable by Parent, on the one hand, and the Stockholders’ Agent, on the other hand, shall be determined by dividing: (x) the quotient obtained for Parent or the Stockholders’ Agent, as the case may be, pursuant to the immediately preceding sentence; by (y) the sum of the quotients for both Parent and the Stockholders’ Agent pursuant to the immediately preceding sentence.

               (b) Adjustments. If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Capital Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction then the Merger Consideration shall be appropriately adjusted.

Parent shall be entitled to retain any Merger Consideration not paid on account of such Dissenting Shares pending resolution of the claims of such holders, and the Eligible Stockholders shall not be entitled to any portion thereof.

Notwithstanding the provisions of Section 1.9(a), if any holder of shares of Company Capital Stock who demands appraisal of such holder’s shares under the DGCL shall effectively withdraw or lose (through the failure to perfect or otherwise) such holder’s right to appraisal, then as of the Closing or the occurrence of such event, whichever later occurs, such holder’s shares of Company Capital Stock shall automatically be converted into the right to receive the applicable Merger Consideration, without interest thereon, as and when payable pursuant to this Agreement, following the surrender of the certificate or certificates representing such shares of Company Capital Stock.

Upon the surrender to Parent of a Company Stock Certificate (or an affidavit of lost stock certificate as described in Section 1.10(d)), together with a duly executed Letter of Transmittal and such other documents as Parent may reasonably request, the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor the Merger Consideration, if any, which such holder has the right to receive pursuant to this Agreement, and the Company Stock Certificate so surrendered shall forthwith be canceled. From and after the Effective Time, each Company Stock Certificate which prior to the Effective Time represented shares of Company Capital Stock shall be deemed to represent only the right to receive the Merger Consideration, if any, payable with respect to such shares, and the holder of each such Company Stock Certificate shall cease to have any rights with respect to the shares of Company Capital Stock formerly represented thereby.

          (b) Payments to Others. If payment or issuance of Merger Consideration in respect of shares of Company Capital Stock converted pursuant to this Agreement is to be made to a Person other than the Person in whose name a surrendered Company Stock Certificate is registered, it shall be a condition to such payment that the Company Stock Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of such payment in a name other than that of the registered holder of the Company Stock Certificate surrendered or shall have established to the satisfaction of Parent that such Tax either has been paid or is not payable.

          (c) Stock Transfer Books. As of the Effective Time, the stock transfer books of the Company shall be closed and there shall not be any further registration of transfers of shares of Company Capital Stock thereafter on the records of the Company.

No interest shall accrue or be paid on any Merger Consideration payable upon the surrender of a Company Stock Certificate which immediately before the Effective Time represented outstanding shares of Company Capital Stock.

          (d) Lost Certificates. In the event any Company Stock Certificate representing shares of Company Capital Stock converted in connection with the Merger pursuant to Section 1.5 shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the payment of any Merger Consideration with respect to the shares of Company Capital Stock previously represented by such Company Stock Certificate, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such amount, form and with such surety as Parent may reasonably direct) as indemnity against any claim that may be made against Parent, the Surviving Corporation or any affiliated party with respect to such Company Stock Certificate.

          (f) Cash in Lieu of Fractional Shares. No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates for any such fractional shares shall be issued. In lieu of such fractional shares, any holder of capital stock of the Company who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, upon surrender of such holder’s Company Stock Certificate(s), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the Average Closing Stock Price.

          (g) Escheat. Notwithstanding anything in this Agreement to the contrary, neither Parent nor any other Person shall be liable to any holder of shares of Company Capital Stock or to any other Person for any amount paid to a public official pursuant to applicable abandoned property law, escheat law or similar Legal Requirement. Any amounts remaining unclaimed by holders of shares of Company Capital Stock three years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Body) shall, to the extent permitted by applicable Legal Requirements, become the property of Parent free and clear of any Encumbrance.

          (h) Withholding. Each of Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or issuable pursuant to this Agreement to any security holder or former security holder of the Company such amounts as Parent determines in good faith are required to be deducted or withheld therefrom or in connection therewith under the Code or any provision of state, local or foreign Tax law or similar Legal Requirement or under any other applicable Legal Requirement.

     1.11 Further Action. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation or Parent with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

          (c) Intentional Misrepresentation; Fraud. Notwithstanding anything to the contrary contained in Section 4.1(a) or Section 4.1(b), the limitations set forth in Section 4.1(a) and Section 4.1(b) shall not apply in the case of claims based upon intentional misrepresentation or fraud.

          (d) Representations Not Limited. The representations, warranties, covenants and obligations of the Company, and the rights and remedies that may be exercised by the Indemnitees, shall not be limited or otherwise affected by or as a result of any information furnished to, or any investigation made by or knowledge of, any of the Indemnitees or any of their Representatives.

          (e) Disclosure Schedule. For purposes of this Agreement, each statement or other item of information set forth in the Disclosure Schedule or in any update to the Disclosure Schedule shall be deemed to be a representation and warranty made by the Company in this Agreement.

     4.2 Indemnification.

          (a) Indemnification. From and after the Effective Time (but subject to Section 4.1), each Indemnitor, severally and not jointly, shall hold harmless and indemnify each of the Indemnitees from and against, and shall compensate and reimburse each of the Indemnitees for, any Damages which are directly or indirectly suffered or incurred by any of the Indemnitees or to which any of the Indemnitees may otherwise directly or indirectly become subject (regardless of whether or not such Damages relate to any third-party claim) and which arise directly or indirectly from or as a direct or indirect result of:

               (i) any inaccuracy in or breach of any representation or warranty made by the Company in this Agreement (without giving effect to any materiality or similar qualification limiting the scope of such representation or warranty);

               (ii) any breach of any covenant or obligation of the Company in this Agreement;

               (iii) the exercise by any stockholder of the Company of such stockholder’s appraisal rights under the DGCL for any amount in excess of what is payable by Parent in accordance with this Agreement or any claim or Legal proceeding by any stockholder of the Company in his, her or its capacity as a holder of securities of the Company who, prior to the Closing, does not execute and deliver to the Company a written consent of the stockholders adopting this Agreement and approving the Certificate Amendment and the other transactions contemplated by the Agreement, a letter of transmittal with respect to their shares of Company Capital Stock and a Stockholder Representation Letter in the form of Exhibit B, each in the form provided to such stockholders by the Company and Parent, against the Company or any of its officers or directors relating to the Merger or any of the other transactions contemplated by this Agreement; or

               (iv) any Legal Proceeding relating to any breach or alleged breach or any other matter of the type referred to in clause “(i),” “(ii)” or “(iii)” above (including any Legal Proceeding commenced by any Indemnitee for the purpose of enforcing any of its rights under this Section 4).

          (b) Damage to Parent. The parties acknowledge and agree that, if the Surviving Corporation suffers, incurs or otherwise becomes subject to any Damages as a result of or in connection with any inaccuracy in or breach of any representation, warranty, covenant or obligation, then (without limiting any of the rights of the Surviving Corporation as an Indemnitee) Parent shall also be deemed, by virtue of its ownership of the stock of the Surviving Corporation, to have incurred Damages as a result of and in connection with such inaccuracy or breach (it being, understood, however, that the Indemnitees shall not be entitled to recover more than once for the same Damages).

     4.3 Limitations.

          (a) Basket. Subject to Section 4.3(b), the Indemnitors shall not be required to make any indemnification payment pursuant to Section 4.2(a)(i) for any inaccuracy in or breach of any representation or warranty in this Agreement until such time as the total amount of all Damages (including the Damages arising from such inaccuracy or breach and all other Damages arising from any other inaccuracies or breaches of any representations or warranties) that have been directly or indirectly suffered or incurred by any one or more of the Indemnitees, or to which any one or more of the Indemnitees has or have otherwise directly or indirectly become subject, exceeds $250,000 in the aggregate (the “Threshold”). If the total amount of such Damages exceeds the Threshold, then the Indemnitees shall be entitled to be indemnified against and compensated and reimbursed for the entire amount of such Damages, and not merely the portion of such Damages exceeding $250,000. No Damages arising from any individual breach of a representation and warranty shall count toward the satisfaction of the Threshold unless the breach of such representation or warranty (or multiple breaches of the same representation and warranty), without regard to any materiality qualifiers contained therein, results in Damages in excess of $10,000.

          (b) Applicability of Basket. The limitations set forth in Section 4.3(a) shall not apply: (i) in the case of intentional misrepresentation or fraud; (ii) to inaccuracies in or breaches of any of

the representations and warranties set forth in Sections 2.3, 2.4(d) and 2.5(b); (iii) the matters referred to in Sections 4.2(a)(ii), and 4.2(a)(iii); or (iv) to the matters referred to in Section 4.2(a)(iv) (to the extent related to any of the matters referred to in clauses “(i)” through “(iii)” of this sentence).

          (c) Recourse to Escrow. Except in the case of intentional misrepresentation or fraud, recourse by the Indemnitees to the Escrow Amount shall be the Indemnitees’ sole and exclusive remedy for monetary Damages resulting from the matters referred to in Section 4.2.

     4.4 No Contribution. Each Indemnitor waives, and acknowledges and agrees that he shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against Merger Sub or the Company in connection with any indemnification obligation or any other liability to which he may become subject under or in connection with this Agreement or any other agreement or document delivered to Parent in connection with this Agreement.

     4.5 Defense of Third-Party Claims. In the event of the assertion or commencement by any Person of any claim or Legal Proceeding (whether against Merger Sub, the Company, Parent or any other Person) with respect to which any Indemnitor may become obligated to hold harmless, indemnify, compensate or reimburse any Indemnitee pursuant to Section 4, Parent shall have the right, at its election, to proceed with the defense of such claim or Legal Proceeding on its own with counsel reasonably satisfactory to the Stockholders’ Agent. If Parent so proceeds with the defense of any such claim or Legal Proceeding:

     (a) subject to the other provisions of Section 4, all reasonable expenses relating to the defense of such claim or Legal Proceeding shall be borne and paid exclusively by the Indemnitors;

     (b) each Indemnitor shall make available to Parent any documents and materials in his possession or control that may be necessary to the defense of such claim or Legal Proceeding;

     (c) Parent shall not settle, adjust or compromise such claim or Legal Proceeding without the consent of the Stockholders’ Agent, such consent not to be unreasonably withheld, delayed or conditioned; and

     (d) notwithstanding Section 4.5(c), with respect to any claim or Legal Proceeding relating to Section 4.2(a)(iii), Intellectual Property or Intellectual Property Rights or any customers or suppliers of the Company or any of its Subsidiaries, Parent shall have the right to settle, adjust or compromise such claim or Legal Proceeding in its sole discretion, with or without the consent of the Stockholders’ Agent; provided that (i) Parent shall consult with the Stockholders’ Agent with respect to any such settlement, adjustment or compromise; and (ii) if Parent settles, adjusts or compromises any such claim or Legal Proceeding without the consent of the Stockholders’ Agent, such settlement, adjustment or compromise shall not be conclusive evidence of the amount of Damages incurred by the Indemnitee in connection with such claim or Legal Proceeding and no Indemnitor shall be deemed to have agreed that the settlement, adjustment or compromise constitutes Damages for which an Indemnitee is entitled to indemnification (it being understood that: (A) if Parent requests that the Stockholders’ Agent consent to a settlement, adjustment or compromise, the Stockholders’ Agent shall not unreasonably withhold or delay such consent; and (B) if Parent pursues a claim against the Indemnitors with respect to any matter for which Parent enters into a settlement, adjustment or compromise without the consent of the Stockholders’ Agent and such claim is submitted to arbitration under the Escrow Agreement, both the Stockholders’ Agent and Parent shall be

entitled to provide to the arbitrator, and the arbitrator shall take into account, evidence with respect to why the amount of the settlement, adjustment or compromise should not (or should) have a bearing on the amount of Damages to which the Indemnitees are entitled. Such evidence may include, without limitation, evidence with respect to the Stockholders’ Agent’s views as to why Parent entered into such settlement, adjustment or compromise (e.g., to avoid a dispute with a major customer of Parent)).

Parent shall give the Stockholders’ Agent prompt notice of the commencement of any such Legal Proceeding against Parent, Merger Sub or the Company; provided, however, that any failure on the part of Parent to so notify the Stockholders’ Agent shall not limit any of the obligations of the Indemnitors under Section 4 (except to the extent such failure materially prejudices the defense of such Legal Proceeding). If Parent does not elect to proceed with the defense of any such claim or Legal Proceeding, the Stockholders’ Agent may proceed with the defense of such claim or Legal Proceeding with counsel reasonably satisfactory to Parent; provided, however, that the Stockholders’ Agent may not settle, adjust or compromise any such claim or Legal Proceeding without the prior written consent of Parent (which consent may not be unreasonably withheld or delayed).

     4.6 Parent Indemnification Obligations. From and after the Effective Time (but subject to Section 4.1), Parent shall hold harmless and indemnify the Eligible Stockholders from and against, and shall compensate and reimburse each of such Eligible Stockholders for, any Damages which are directly or indirectly suffered or incurred by any of the Eligible Stockholders or to which any of the Eligible Stockholders may otherwise directly or indirectly become subject (regardless of whether or not such Damages relate to any third-party claim) and which arise directly or indirectly from or as a direct or indirect result of:

          (i) any inaccuracy in or breach of any representation or warranty made by Parent or Merger Sub in Sections 3.1, 3.2, 3.3 or 3.8 (without giving effect to any materiality or similar qualification limiting the scope of such representation or warranty);

          (ii) any breach of any covenant or obligation of Parent or Merger Sub in this Agreement;

          (iii) any Legal Proceeding relating to any breach or alleged breach or any other matter of the type referred to in clause “(i),” or “(ii)” above (including any Legal Proceeding commenced by any Eligible Stockholder for the purpose of enforcing any of his, her or its rights under this Section 4).

          (b) Limitations on Damages. Except in the case of intentional misrepresentation or fraud, the total amount of indemnification payments that Parent can be required to make to the Eligible Stockholders pursuant to this Section 4.6 shall be limited to $7 million dollars.

5. Miscellaneous Provisions

     5.1 Stockholders’ Agent.

          (a) Appointment. By virtue of the adoption of this Agreement, the Eligible Stockholders irrevocably nominate, constitute and appoint Alta Berkeley LLP as the agent and true and lawful attorney in fact of the stockholders (the “Stockholders’ Agent”), with full power of substitution, to act in the name, place and stead of the Eligible Stockholders for purposes of executing any documents and taking any actions that the Stockholders’ Agent may, in his sole discretion, determine to be necessary, desirable or appropriate in connection with any matter set forth in this Agreement or in any Ancillary

Agreement, including any claims for indemnification, compensation or reimbursement under Section 4 or under the Escrow Agreement. Alta Berkeley LLP hereby accepts its appointment as Stockholders’ Agent.

          (b) Authority. The Eligible Stockholders grant to the Stockholders’ Agent full authority to execute, deliver, acknowledge, certify and file on behalf of such Eligible Stockholders (in the name of any or all of the Eligible Stockholders or otherwise) any and all documents that the Stockholders’ Agent may, in his sole discretion, determine to be necessary, desirable or appropriate, in such forms and containing such provisions as the Stockholders’ Agent may, in his sole discretion, determine to be appropriate, in performing his duties as contemplated by Section 5.1(a). Notwithstanding anything to the contrary contained in this Agreement or in any other agreement executed in connection with the transactions contemplated hereby: (i) each Indemnitee shall be entitled to deal exclusively with the Stockholders’ Agent on all matters relating to this Agreement or any Ancillary Agreement, including any claim for indemnification, compensation or reimbursement under Section 4 or under the Escrow Agreement; and (ii) each Indemnitee shall be entitled to rely conclusively (without further evidence of any kind whatsoever) on any document executed or purported to be executed on behalf of any Eligible Stockholder by the Stockholders’ Agent, and on any other action taken or purported to be taken on behalf of any stockholder by the Stockholders’ Agent, as fully binding upon such stockholder.

          (c) Power of Attorney. The Eligible Stockholders recognize and intend that the power of attorney granted in Section 5.1(a): (i) is coupled with an interest and is irrevocable; (ii) may be delegated by the Stockholders’ Agent; and (iii) shall survive the death or incapacity of each of the Eligible Stockholders.

          (d) Replacement. If the Stockholders’ Agent shall die, resign, become disabled or otherwise be unable to fulfill his responsibilities hereunder, the Eligible Stockholders shall (by consent of those Persons entitled to at least a majority of the Merger Consideration), within 10 days after such death, disability or inability, appoint a successor to the Stockholders’ Agent (who shall be reasonably satisfactory to Parent) and immediately thereafter notify Parent of the identity of such successor. Any such successor shall succeed the Stockholders’ Agent as Stockholders’ Agent hereunder. If for any reason there is no Stockholders’ Agent at any time, all references herein to the Stockholders’ Agent shall be deemed to refer to the Eligible Stockholders.

     5.2 Employee Benefit Matters.

          (a) 401(k) Plan. Effective as of the Closing Date, the Company Employees shall no longer make contributions or receive matching contributions to any Company Employee Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (the “401(k) Plans”), and the Company shall have taken all such action prior to the Closing Date as may be reasonably required to achieve this result. Each Company Employee shall, as of the Closing Date, become fully vested in his or her account balance under the 401(k) Plans. The Company shall request the trustees for each the 401(k) Plans, to take whatever actions are reasonably necessary or appropriate to effect a trust-to-trust transfer of the accounts of Company Employees in the 401(k) Plans into a plan designated by the Parent to accept the transferred accounts, and the Parent shall take whatever actions are reasonably necessary or appropriate in order for such plan to accept the transferred accounts, and shall provide a certification that the plan to which the assets are being transferred is qualified under Section 401(a) of the Code.

          (b) Service Credit. Parent shall: (i) credit the employees of the Company who become employees of Parent as of the Closing or remain employees of the Company (“Continuing Employees”) for their past service with the Company for purposes of eligibility and vesting (but not benefit accrual purposes, including matching contributions for periods prior to actual participation) under

Parent’s 401(k), medical, vision and dental plans, and/or any other benefit plan, program or arrangement of Parent maintained or contributed to by Parent or any of its Subsidiaries for its employees; and (ii) grant the Continuing Employees service credit for purposes of Parent’s vacation leave policy.

          (c) Retention Arrangements. Parent shall adopt the Retention Arrangements and ensure that any payments required to be made pursuant to the Retention Arrangements are made on a timely basis.

     5.3 Directors and Officers Indemnification; Insurance.

          (a) Indemnification. Parent shall cause all rights to exculpation, advancement of expenses and indemnification for acts or omissions occurring at or prior to the Closing (including any matters arising in connection with the transactions contemplated by this Agreement), whether asserted or claimed prior to, at or after the Closing, now existing in favor of the current or former directors or officers of the Company or its Subsidiaries in their capacities as such (the “Director Indemnitees”) as provided in the respective Charter Documents of the Company and its Subsidiaries or in any agreement set forth in the Disclosure Schedule, in each case as in effect as of the date of this Agreement, to survive the Closing, to continue in full force and effect and to be satisfied as required pursuant to their terms.

          (b) Third Party Beneficiaries. Director Indemnitees to whom this Section 5.3 applies shall be third party beneficiaries of this Section 5.3. The provisions of this Section 5.3 are intended to be for the benefit of and enforceable by each Director Indemnitee and his or her successors, heirs or representatives. The indemnification and insurance rights provided for herein shall not be deemed exclusive of any other rights to which a Director Indemnitee is entitled, whether pursuant to Law, Contract or otherwise.

          (c) Directors’ and Officers Insurance. Parent shall, or shall cause the Company to, provide for a period of not less than six years after the Closing Date officers’ and directors’ liability insurance coverage for those persons who, as of the date of this Agreement, are officers and directors of the Company, under a separate “tail policy” (or other policy) with respect to their acts and omissions as directors and officers of the Company occurring at or prior to the Closing Date that is at least as favorable to such officers and directors as the existing coverage provided by the Company, provided however, that in no event will the Company or Parent be required to expend annually in excess of 150% of the annual premium currently paid by the Company under its current policy.

          (d) Merger or Consolidation. In the event the Company or its successors or assigns consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, then proper provision shall be made so that the successors and assigns of the Company, or at Parent’s option, Parent, shall assume the obligations set forth in this Section 5.3.

     5.4 Further Assurances; Limitations. Each party hereto shall execute and cause to be delivered to each other party hereto such instruments and other documents, and shall take such other actions, as such other party may reasonably request (prior to, at or after the Closing) for the purpose of carrying out or evidencing any of the transactions contemplated by this Agreement. Notwithstanding the foregoing or any other provision of this Agreement, the parties acknowledge and agree that while Parent currently believes that it is in its best interest that it and the Company use commercially reasonable efforts to generate Net Product Revenues, it is understood and agreed that neither Parent nor the Company has any obligation to use any specified efforts to generate Net Product Revenues (or to sell or license Specified Company Products or enter into or renew related contracts); provided, however, that Parent will: (a) not alter or terminate the performance based compensation arrangements implemented in

connection with the Merger and (b) offer commissions to those employees responsible for selling Specified Company Products in such amounts and at such percentages, as applicable, as are similar to those offered to other employees of Parent selling similar products; provided further that Parent may in its good faith judgment discontinue the sale or license of any Specified Company Product and the entering into or renewal of related contracts.

     5.5 Fees and Expenses. Subject to Section 1, Section 4 and the Escrow Agreement, each party to this Agreement shall bear and pay all fees, costs and expenses that have been incurred or that are incurred in the future by such party in connection with the transactions contemplated by this Agreement, including all fees, costs and expenses incurred by such party in connection with or by virtue of: (a) the negotiation, preparation and review of this Agreement (including the Disclosure Schedule) and all agreements, certificates, opinions and other instruments and documents delivered or to be delivered in connection with the transactions contemplated by this Agreement; (b) the preparation and submission of any filing or notice required to be made or given in connection with any of the transactions contemplated by this Agreement, and the obtaining of any Consent required to be obtained in connection with any of such transactions; and (c) the consummation of the Merger; provided, however, that the stockholders of the Company shall bear and pay all such fees, costs and expenses that have been incurred or that are incurred by or on behalf of the Company and its Subsidiaries.

     5.6 Attorneys’ Fees. If any Legal Proceeding relating to this Agreement or the enforcement of any provision of this Agreement is brought against any party hereto, the prevailing party shall be entitled to recover reasonable attorneys’ fees, costs and disbursements (in addition to any other relief to which the prevailing party may be entitled).

          (a) Governing Law. This Agreement shall be construed in accordance with, and governed in all respects by, the internal laws of the State of Delaware (without giving effect to principles of conflicts of laws).

          (b) Venue. Except as otherwise provided in the Escrow Agreement or in Section 5.10(c), any Legal Proceeding relating to this Agreement or the enforcement of any provision of this Agreement (including a Legal Proceeding based upon intentional misrepresentation or fraud) may be brought or otherwise commenced in any state or federal court located in the State of Delaware. Each party to this Agreement: (i) expressly and irrevocably consents and submits to the jurisdiction of each state and federal court located in the State of Delaware (and each appellate court located in the State of Delaware) in connection with any such Legal Proceeding; (ii) agrees that each state and federal court located in the State of Delaware shall be deemed to be a convenient forum; and (iii) agrees not to assert (by way of motion, as a defense or otherwise), in any such Legal Proceeding commenced in any state or federal court located in the State of Delaware, any claim that such party is not subject personally to the jurisdiction of such court, that such Legal Proceeding has been brought in an inconvenient forum, that the venue of such proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court.

          (c) Indemnification Claims. Any claim for indemnification, compensation or reimbursement pursuant to Section 4 shall be brought and resolved exclusively in accordance with the

Escrow Agreement (it being understood that nothing in this Section 5.10(c) shall prevent Parent from seeking preliminary injunctive relief from a court of competent jurisdiction).

     5.11 Successors and Assigns. This Agreement shall be binding upon: (a) the Company and its successors and assigns (if any); (b) Parent and its successors and assigns (if any); and (c) Merger Sub and its successors and assigns (if any). This Agreement shall inure to the benefit of: (i) the Company; (ii) Parent; (iii) Merger Sub; (iv) the other Indemnitees; (v) the Director Idemnitees (to the extent set forth in Section 5.3); and (vi) the respective successors and assigns (if any) of the foregoing. After the Closing Date, Parent may freely assign any or all of its rights under this Agreement (including its indemnification rights under Section 4), in whole or in part, to any other Person without obtaining the consent or approval of any other party hereto or of any other Person.

     5.12 Remedies Cumulative; Specific Performance. The rights and remedies of the parties hereto shall be cumulative (and not alternative). The parties to this Agreement agree that, in the event of any breach or threatened breach by any party to this Agreement of any covenant, obligation or other provision set forth in this Agreement, for the benefit of any other party to this Agreement: (a) such other party shall be entitled (in addition to any other remedy that may be available to it) to: (i) a decree or order of specific performance or mandamus to enforce the observance and performance of such covenant, obligation or other provision; and (ii) an injunction restraining such breach or threatened breach; and (b) such other party shall not be required to provide any bond or other security in connection with any such decree, order or injunction or in connection with any related action or Legal Proceeding.

     5.13 Waiver. No failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No Person shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Person; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

     5.14 Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives any and all right to trial by jury in any Legal Proceeding arising out of or related to this Agreement or the transactions contemplated hereby.

     5.15 Amendments. This Agreement may not be amended, modified, altered or supplemented other than by means of a written instrument duly executed and delivered: (a) prior to the Closing Date, on behalf of all parties hereto; and (b) after the Closing Date, on behalf of Parent and the Stockholders’ Agent (acting exclusively for and on behalf of all of the Eligible Stockholders).

     5.16 Severability. In the event that any provision of this Agreement, or the application of any such provision to any Person or set of circumstances, shall be determined to be invalid, unlawful, void or unenforceable to any extent, the remainder of this Agreement, and the application of such provision to Persons or circumstances other than those as to which it is determined to be invalid, unlawful, void or unenforceable, shall not be impaired or otherwise affected and shall continue to be valid and enforceable to the fullest extent permitted by law.

     5.17 Parties-in-Interest. Except for the provisions of Section 4, none of the provisions of this Agreement is intended to provide any rights or remedies to any Person other than the parties hereto and their respective successors and assigns (if any). Without limiting the generality of the foregoing, no

Company Employee shall have any rights or remedies under any of the provisions of this Agreement (including Section 5.2).

     5.18 Entire Agreement. This Agreement and the other agreements referred to herein set forth the entire understanding of the parties hereto relating to the subject matter hereof and thereof and supersede all prior agreements and understandings among or between any of the parties relating to the subject matter hereof and thereof; provided, however, that neither the Confidentiality Agreement nor the No-Shop Agreement shall be superseded by this Agreement and shall remain in effect in accordance with its terms until the earlier of: (a) the Effective Time; or (b) the date on which such Confidentiality Agreement or No-Shop Agreement is terminated in accordance with its terms.

     5.19 Disclosure Schedule. The Disclosure Schedule shall be arranged in separate parts corresponding to the numbered and lettered sections contained herein permitting such disclosure, provided that the information and disclosures contained in any section of the Disclosure Schedule shall be deemed to be disclosed and incorporated by reference in any other section of the Disclosure Schedule as though fully set forth in such other section for which the applicability of such information and disclosure is reasonably apparent on the face of such information or disclosure.

     5.20 Construction.

          (a) Gender; Etc. If a term is defined as one part of speech (such as a noun), it shall have a corresponding meaning when used as another part of speech (such as a verb). Unless indicated otherwise, terms defined in the singular have the corresponding meanings in the plural, and vice versa. Unless the context of this Agreement clearly requires otherwise, words importing the masculine gender shall include the feminine and neutral genders and vice versa. The words “hereof,” “hereto,” “hereby,” “herein,” “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular section or article in which such words appear. Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless Business Days are specified. Whenever any action must be taken hereunder on or by a day that is not a Business Day, then such action may be validly taken on or by the next day that is a Business Day. The use of “or” is not intended to be exclusive unless expressly indicated otherwise.

          (b) Ambiguities. Each party hereto acknowledges that it and its attorney has reviewed this Agreement and agrees that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement.

          (c) Including. As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

          (d) References. All article, section, schedule, exhibit and annex references used in this Agreement are to articles, sections, schedules, exhibits and annexes to this Agreement unless otherwise specified. All terms defined in this Agreement shall have their defined meanings when used in any Annex, Exhibit or Schedule to this Agreement or any certificate or other document made or delivered pursuant hereto, unless otherwise defined therein. The schedules, exhibits and annexes attached to this Agreement constitute a part of this Agreement and are incorporated herein for all purposes. The table of contents and captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement.
