E. 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 VII, 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 Xxxxxxx Procter LLP, Xxxxxxxx Xxxxx, Xxxxxx, XX 00000, 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 B 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 C 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 directors of Merger Sub as of immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation and the officers of Merger Sub as of immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, in each case, 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 immediately following the Effective Time the Board of Directors of Parent shall consist of the following seven (7) members: five (5) members, which shall be those persons set forth on Annex B hereto (it being understood that prior to the Effective Time the persons set forth on Annex B may only be changed by mutual written consent of the parties) and two (2) members acceptable to the other members. 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 Parent Name Change. At or immediately prior to the Effective Time, Parent shall take all actions necessary to change the name of Parent to “Arcion Therapeutics, Inc.”

ARTICLE II

CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

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 Company Series A Preferred Stock. Each share of Series A Preferred Stock, par value $0.01 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(c)), shall be converted, subject to Section 2.2(c), 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 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.

(b) Conversion of Company Common Stock. Each share of common stock, par value $0.01 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(c)), shall be converted, subject to Section 2.2(c), into the right to receive a number of shares of Parent Common Stock equal to the Common Exchange Ratio. All such shares of Company Common 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 Common Stock was converted in the Merger. Certificates previously representing shares of Company Common 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) Cancellation of Certain Shares. Each share of Company Common Stock or Company Series A 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.

(d) 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.

(e) Change in Shares. The parties acknowledge and agree that the Exchange Ratios assume that no Reverse Stock Split has occurred following the Agreement Date and prior to the Effective Time. If between the Agreement Date and the Effective Time the outstanding shares of Parent Common Stock, Company Series A 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 Series A 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 Series A Preferred Stock. The Exchange Agent shall, pursuant to irrevocable instructions, 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 Series A 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 Series A 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 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 Series A 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 Series A 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 Series A 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 Series A 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 Series A Preferred Stock in accordance with the terms hereof (including any cash paid pursuant to 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 Series A Preferred Stock for twelve (12) months after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Common Stock or Company Series A 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 Series A 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 Series A 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 Series A 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 Series A 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 Series A 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 voluntary payments with respect to, or offer to settle, any claim with respect to dissenting shares without the consent of Parent.

2.4 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, shall be assumed by Parent in accordance with Section 6.18. At the Effective Time, Parent shall assume each of the Company Stock Option Plans, subject to adjustment as provided therein such that options granted under each such plan after the Effective Time, if any, shall be exercisable for the purchase of Parent Common Stock. The Company shall take any actions and provide any notices as may be necessary to effectuate the foregoing.

2.5 FIRPTA Certificate. At the Closing, the Company shall provide the Parent with a certificate in accordance with Treasury Regulations Section 1.1445-2(c)(3).

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

Except as set forth in the disclosure schedule delivered by Parent to the Company prior to the execution of this Agreement (the “Parent Disclosure Schedule”), which identifies exceptions by specific section references (provided, that any matter disclosed in any section of the Parent Disclosure Schedule shall be considered disclosed for other sections of the Parent Disclosure Schedule, but only to the extent such matter on its face would be reasonably expected to be pertinent to a particular section of the Disclosure Schedule in light of the disclosure made in such section), Parent and Merger Sub hereby jointly and severally represent and warrant to the Company as follows:

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. Each Subsidiary of Parent has been duly organized, and is validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization, as the case may be. Parent and each of its Subsidiaries has the requisite power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted. 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 the Parent Disclosure Schedule, none of Parent or any of its Subsidiaries holds an Equity Interest in any other person.

3.2 Certificate of Incorporation and By-laws; Corporate Books and Records. The copies of Parent’s Amended and Restated Certificate of Incorporation (the “Parent Certificate”) and Amended and Restated By-laws (the “Parent By-laws”) that are listed as exhibits to Parent’s Form 10-K for the year ended December 31, 2008 (the “Parent Form 10-K”) are complete and correct copies thereof as in effect on the date hereof. Parent is not in violation of any of the provisions of the Parent Certificate or Parent By-laws. True and complete copies of all minute books of Parent have been made available by Parent to the Company.

3.3 Capitalization

(a) The authorized capital stock of Parent consists of 100,000,000 shares of Parent Common Stock and 5,000,000 shares of preferred stock, par value $0.001 per share (the “Parent Preferred Stock”). As of the Agreement Date, (A) 40,467,057 shares of Parent Common Stock were issued and outstanding, all of which were validly issued and fully paid, nonassessable and free of preemptive rights, (B) no shares of Parent Preferred Stock were issued and outstanding, (C) no shares were held in treasury, (D) 2,007,714 shares of Parent Common Stock were issuable upon exercise of options to purchase Parent Common Stock (“Parent Options”) outstanding on such date, (E) 1,193,388 shares of Parent Common Stock were issuable upon exercise of all outstanding warrants to purchase Equity Interests of Parent (“Parent Warrants”) and (F) 3,335 shares of Parent Restricted Stock were outstanding. All capital stock or other equity securities of Parent have been issued in compliance with applicable federal and state securities laws.

(b) As of the Agreement Date, except for Parent Options, Parent Warrants and Parent Restricted Stock (collectively, “Parent Stock Rights”), there were no options, warrants or other rights, agreements, arrangements or commitments of any character to which Parent or any of its Subsidiaries is a party or by which Parent or any of its Subsidiaries is bound relating to the issued or unissued capital stock or other Equity Interests of Parent or any of its Subsidiaries, or securities convertible into or exchangeable for such capital stock or other Equity Interests, or obligating Parent or any of its Subsidiaries to issue or sell any shares of its capital stock or other Equity Interests, or securities convertible into or exchangeable for such capital stock of, or other Equity Interests in, Parent or any of its Subsidiaries. Section 3.3(b) of the Parent Disclosure Schedule sets forth a true and complete list, as of the date hereof, of all Parent Stock Rights, and with respect to each Parent Stock Right, the name of the holder thereof, the number of shares subject to such Parent Stock Right, the type of Parent Stock Right, the prices at which any such outstanding Parent Stock Right may be exercised, the number of Parent Stock Rights outstanding at each such price and the vesting schedule of each Parent Stock Right that is a Parent Option. All shares of Parent Common Stock subject to issuance under Parent Stock Option Plans, upon issuance on the terms and conditions specified in the instruments pursuant to which they are issuable, will be duly authorized, validly issued, fully paid, nonassessable and free of preemptive rights. Section 3.3(b) of the Parent Disclosure Schedule sets forth the restricted stock agreements (and the acceleration provisions contained therein) pursuant to which all shares of Parent Restricted Stock have been granted.

(c) Except for the Parent Voting Agreements and contractual obligations contained in documents filed as exhibits to the Parent Form 10-K, as of the Agreement Date there are no outstanding contractual obligations of Parent or any of its Subsidiaries (A) restricting the transfer of, (B) affecting the voting rights of, (C) requiring the repurchase, redemption or disposition of, or containing any right of first refusal with respect to, (D) requiring the registration for sale of, or (E) granting any preemptive or antidilutive right with respect to, any shares of Parent Common Stock or any capital stock of, or other Equity Interests in, Parent or any of its Subsidiaries.

6.6 No Solicitation of Transactions.

(a) Each of Parent and the Company agrees that neither it nor any of its Subsidiaries shall, and that it shall ensure that its and its Subsidiaries’ Representatives do not, directly or indirectly: (i) initiate, solicit, induce, knowingly encourage or take any other action designed to, or which could reasonably be expected to, facilitate, an Acquisition Proposal or Acquisition Inquiry or the making, submission or announcement of, any Acquisition Proposal or Acquisition Inquiry, (ii) furnish to any person any nonpublic information in connection with or in response to any Acquisition Proposal or Acquisition Inquiry, (iii) participate or engage in discussions or negotiations with any person with respect to any Acquisition Proposal or Acquisition Inquiry, except to notify such person as to the existence of these provisions of Section 6.6(a), (iv) approve, endorse or recommend any Acquisition Proposal or Acquisition Inquiry, or (v) enter into any letter of intent or similar document or any Contract contemplating or otherwise relating to any Acquisition Proposal or Acquisition Inquiry; provided, that so long as there has been no breach of this Section 6.6(a), prior to obtaining the Parent Stockholder Approval, Parent may, or prior to obtaining the Company Stockholder Approval, the Company may, in response to a written Acquisition Proposal, participate in discussions or negotiations with, request clarifications from, or furnish nonpublic information to, any person in response to an Acquisition Proposal made by such person (and not withdrawn) if (x) at least two business days prior to furnishing any such nonpublic information to, or entering into discussions or negotiations with, such person, such party gives the other party written notice of the identity of such person and of such party’s intention to furnish nonpublic information to, or enter into discussions or negotiations with, such person and such party receives from such person an executed confidentiality agreement containing terms and conditions at least as favorable to such party as the provisions of the Confidentiality Agreement, (y) the Parent Board or Company Board, as applicable, reasonably determines in good faith, after having taken into account the advice of its nationally recognized financial advisor (which may be its current outside financial advisor), that such Acquisition Proposal could reasonably be expected to lead to a Superior Proposal, and (z) the Parent Board or 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 its stockholders under applicable Law. Without limiting the foregoing, the parties agree that any violation of the restrictions set forth in this Section 6.6(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 6.6(a). For purposes of this Agreement, a Representative shall be deemed to have breached this Section 6.6(a) if such Representative takes any action that would constitute a breach by Parent or the Company of this Section 6.6(a) were such party to take such action directly. Parent and the Company shall immediately terminate, and shall cause its Subsidiaries and its Subsidiaries’ Representatives to immediately terminate, all discussions or negotiations, if any, with any third party ongoing as of the date of this Agreement with respect to, or any that could reasonably be expected to lead to or contemplate the possibility of, an Acquisition Proposal or Acquisition Inquiry unless and until such third party submits an Acquisition Inquiry or Acquisition Proposal, in which case the foregoing provisions shall apply equally with respect to such third party as to any other third party with whom no discussions or negotiations were taking place as of the date of this Agreement.

(b) Neither the Parent Board or Company Board nor any committee thereof shall (i) withdraw, modify or amend, or formally propose to withdraw, modify or amend, in a manner adverse to the other party hereto, Parent Recommendation or the Company Recommendation, as the case may be or (ii) resolve to do any of the foregoing; provided, that Parent Board or the Company Board, as the case may be, may withdraw, modify or amend the Parent Recommendation or Company Recommendation, as applicable, prior to obtaining the approval of its stockholders as contemplated by Section 6.4 (an “Adverse Recommendation Change”) if, (x) Parent or the Company, as the case may be, has complied with its obligations under this Section 6.6, (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 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 one or more competing proposal(s) (which shall be considered and negotiated by the 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(s), the Superior Proposal continues to constitutes a Superior Proposal. In the event of any material revisions to a Superior Proposal (including, without limitation, any revision in price), Parent or the Company, as applicable, shall be required to deliver a new notice to Parent or the Company, as applicable, and to again comply with the requirements of this Section 6.6(b) with respect to such new notice. Neither the Parent Board’s ability to take any of the actions described in this Section 6.6(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 6.4(b). Neither the Company Board’s ability to take any of the actions described in this Section 6.6(b) nor the commencement, disclosure, announcement or submission to it of an Acquisition Proposal shall relieve the Company’s obligation to seek to obtain the Company Stockholder Written Consent, pursuant to Section 6.4(b).

(c) In addition to the obligations set forth in Section 6.6(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.

(e) Nothing contained in this Agreement shall be deemed to restrict the Parent from complying with Rules 14d-9 or 14e-2 under the Exchange Act with regard to an Acquisition Proposal; provided, that any such disclosure shall be deemed to be an Adverse Recommendation Change unless the Parent Board expressly reaffirms the Parent Recommendation (x) in such disclosure or (y) within two (2) business days after requested to do so by the Company.

(a) Parent and the Company shall use their commercially reasonable efforts to (A) take, or cause to be taken, all appropriate action, and do, or cause to be done, all things necessary, proper or advisable under applicable Law or otherwise to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable, (B) obtain from any Governmental Entity any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained or made by Parent or the Company or any of their respective Subsidiaries, or to avoid any action or proceeding by any Governmental Entity (including, without limitation, those in connection with the HSR Act), in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions contemplated herein, including, without limitation, the Merger, and (C) make all necessary filings, and thereafter make any other required submissions, with respect to this Agreement and the Merger required under (x) the Securities Act and the Exchange Act, and any other applicable federal or state securities Laws, (y) the HSR Act, and (z) any other applicable Law; provided, that Parent and the Company shall cooperate with each other in connection with the making of all such filings, including, if requested, by providing copies of all such documents to the non-filing party and its advisors prior to filing and, if requested, to accept all reasonable additions, deletions or changes suggested in connection therewith; provided, that nothing in this Section 6.7(a) shall require the expenditure of money by the Company or Parent to a third party in exchange for any such consent (other than nominal filing or processing fees). Parent and the Company shall use commercially reasonable 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 Proxy 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 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. In the event that either party shall fail to obtain any third party consent described in the first sentence of this Section 6.7(b), such party shall use all commercially reasonable efforts, and shall take any such actions reasonably requested by the other party hereto, to minimize any adverse effect upon Parent and the Company, their respective Subsidiaries, and their respective businesses resulting, or which could reasonably be expected to result after the Effective Time, from the failure to obtain such consent.

6.8 Certain Notices. From and after the Agreement Date until the Effective Time, each party hereto shall promptly notify the other party hereto of (A) the occurrence, or non-occurrence, of any event that would be likely to cause any condition to the obligations of any party to effect the Merger and the other transactions contemplated by this Agreement not to be satisfied, or (B) the failure of Parent or the Company, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any party to effect the Merger and the other transactions contemplated by this Agreement not to be satisfied; provided, that the delivery of any notice pursuant to this Section 6.8 shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to the Agreement Date or otherwise limit or affect the remedies available hereunder to the party receiving such notice.

6.9 Public Announcements. 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 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 6.9, in the event that there has been a change of recommendation pursuant to Section 6.6, 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.

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.

6.11 Employee Benefit and Section 16 Matters.

(a) Prior to the Effective Time, Parent Board, or an appropriate committee of non-employee directors, shall adopt a resolution in accordance with the procedures set forth in Rule 16b-3 promulgated under the Exchange Act and in accordance with the Interpretative Letter dated January 12, 1999 issued by the SEC relating to Rule 16b-3, 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.

(c) The parties hereto acknowledge and agree that all provisions contained in this Section 6.11 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 6.11 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.

6.12 Indemnification of Directors and Officers.

(a) The Company, Merger Sub and Parent agree that the indemnification and exculpation 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 Agreement Date for their acts and omissions as directors and officers thereof prior to the Effective Time, shall survive the Merger and be honored and be given full force and effect by Parent and Merger Sub to the fullest extent permitted by Delaware Law for a period of six years from Effective Time.

(b) For six years from the Effective Time, Parent shall provide to the Company’s directors and officers, as of the Agreement Date, 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, 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 Agreement Date for D&O Insurance with respect to the Company. 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.

(c) From and after the Effective Time, Parent and the Surviving Corporation also agree to indemnify and hold harmless the present and former officers and directors of the Company in respect of acts or omissions occurring prior to the Effective Time to the extent provided in any written indemnification agreements listed in Section 6.12(c) of the Company Disclosure Schedule between the Company and such officers and directors.

6.15 Takeover Statutes. If any anti-takeover, control share acquisition, fair price, moratorium or other similar statute is or may become applicable to the Merger or the other transactions contemplated by this Agreement, each of Parent and the Company and their respective Boards of Directors shall grant such approvals and take such lawful actions as are necessary to ensure that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise take such lawful actions to eliminate or minimize the effects of such statute and any regulations promulgated thereunder on such transactions.

6.16 Reorganization. It is the intent of all parties hereto that the Merger be treated as a “reorganization” within the meaning of Section 368(a) of the Code. The parties hereto adopt this Agreement as a “plan or reorganization” within the meaning of Treasury Regulations Section 1.368-2(g). Notwithstanding anything herein to the contrary, each of Merger Sub, Parent and the Company shall use commercially reasonable efforts to cause the Merger to qualify, and will not take any actions, or fail to take any action, which could reasonably be expected to prevent the Merger from qualifying as a reorganization under the provisions of Section 368(a) of the Code. Merger Sub, Parent, the Company and the Surviving Corporation shall report, to the extent required or permitted by the Code or the regulations thereunder, the Merger for United States federal income tax purposes as a reorganization within the meaning of Section of 368(a) of the Code and shall file all Tax Returns consistent with the foregoing and shall not take any position (whether in audits, Tax Returns or otherwise) that is inconsistent with such treatment or unless required to do so by applicable law. Parent and the Company will each make available to the other party and their respective legal counsel copies of all returns requested by the other party.

The Company shall deliver to each of Xxxxxxx Procter LLP and Xxxxxx Godward Kronish LLP a “Tax Representation Letter,” dated as of the Closing Date and signed by an officer of the Company, containing representations and covenants of the Company, and Parent shall deliver to each of Xxxxxxx Procter LLP and Cooley Godward Kronish LLP a “Tax Representation Letter,” dated as of the Closing Date and signed by an officer of Parent, containing representations and covenants of Parent, in each case as shall be reasonably necessary or appropriate to enable each of Xxxxxxx Procter LLP and Cooley Godward Kronish LLP to render the opinion described in Section 7.3(h) of this Agreement.

6.17 Transfer Taxes. Parent will pay all federal, state and local sales, stamp, documentary, recording, value added, registration, conveyance and real estate and other transfer Taxes, if any, due as a result of the transactions contemplated by this Agreement whether imposed by law on Parent or Company Stockholders (collectively, “Transfer Taxes”). The

party required under applicable law to make any filing with respect to any Transfer Taxes will timely file the necessary documentation and Tax Returns and, upon request, will furnish proof of filing (and payment) to the other party.

6.18 Stock Options.

(a) At the Effective Time, each outstanding Company Option will, on the terms and subject to the conditions set forth in this Agreement, be assumed by Parent. Each Company Option so assumed by Parent under this Agreement will continue to have, and be subject to, the same terms and conditions (including, if applicable, the vesting arrangements and other term and conditions set forth in the applicable Company Stock Option Plan, if any, pursuant to which the Company Option was issued and the applicable option agreement between the Company and the optionee with regard to the Company Option) as are in effect immediately prior to the Effective Time, except that (i) each Company Option will be exercisable for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock that were issuable upon exercise of such Company Option immediately prior to the Effective Time multiplied by 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 assumed Company Option will be equal to the quotient determined by dividing (A) the per share exercise price of Company Common Stock at which such Company Option was exercisable immediately prior to the Effective Time by (B) the Common Exchange Ratio, rounded up to the nearest whole cent.

(b) It is intended that Company Options assumed by Parent shall be adjusted in a manner consistent with Section 424 of the Code (whether or not such Company Options qualify as incentive stock options under Section 422 of the Code) and the provisions of this Section 6.17 shall be applied consistent with such intent.

6.19 Form S-8. Parent agrees to file a registration statement on Form S-8 for the shares of Parent Common Stock issuable with respect to assumed Company Options promptly, but in no event later than ten (10) business days, following the Effective Time and shall maintain the effectiveness of such registration statement thereafter for so long as any such Company Options remain outstanding.

6.20 Note and Security Disposition. Concurrently with the execution of this Agreement, certain holders of the Parent Securities (the “Investors”) have (1) entered into an Amendment No. 2 to Securities Purchase Agreement to amend the Securities Purchase Agreement, dated January 20, 2009, as amended, among Parent and the Investors (collectively, the “Securities Purchase Agreement”) and (2) entered into a Reinvestment Agreement with Parent pursuant to which, subject to the terms and conditions set forth therein, (i) concurrently with the Closing, such Investors shall purchase shares of Parent Common Stock for an aggregate purchase price equal to the total proceeds received in connection with the redemption of their Parent Securities under the Securities Purchase Agreement and (ii) in connection with the transactions contemplated by this Agreement, such Investors have agreed to elect to redeem all of their Parent Notes for an amount equal to 100% of the principal amount of such Parent Notes plus all accrued but unpaid interest and to purchase shares of Parent Common Stock for an aggregate purchase price equal to the total proceeds received in connection with such redemption (collectively, the “Note and Security Disposition”).

6.21 Parent Name Change. At or immediately prior to the Effective Time, Parent shall take all actions necessary to execute and file a certificate of amendment to the Parent Certificate with the Secretary of State of the State of Delaware to provide that Article I of the Parent Certificate shall read: “The name of the corporation is Arcion Therapeutics, Inc.

FORM OF PARENT VOTING AGREEMENT

VOTING AGREEMENT

THIS VOTING AGREEMENT (“Agreement”), dated as of August __, 2009, is made by and between Arcion Therapeutics, Inc., a Delaware corporation (“Company”), and the undersigned holder (the “Stockholder”) of shares (the “Shares”) of common stock, par value $0.001 per share, of Anesiva, Inc., a Delaware corporation (“Parent”).

WHEREAS, Parent, Arca Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), each of the stockholders of Company and Company have entered into an Agreement and Plan of Merger, dated as of even date herewith (as such agreement may be subsequently amended or modified, the “Merger Agreement”), providing for the merger of Merger Sub with and into the Company (the “Merger”);

WHEREAS, the Stockholder beneficially owns and has sole or shared voting power with respect to the number of Shares, and holds stock options or other rights to acquire the number of Shares indicated opposite the Stockholder’s name on Schedule 1 attached hereto;

WHEREAS, as an inducement and a condition to the willingness of Company to enter into the Merger Agreement, and in consideration of the substantial expenses incurred and to be incurred by them in connection therewith, the Stockholder has agreed to enter into and perform this Agreement; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Merger Agreement.

NOW, THEREFORE, in consideration of, and as a condition to, Company entering into the Merger Agreement and proceeding with the transactions contemplated thereby, and in consideration of the expenses incurred and to be incurred by Company in connection therewith, the Stockholder and Company agree as follows:

1. Agreement to Vote Shares. The Stockholder agrees that, prior to the Expiration Date (as defined below), at any meeting of the stockholders of Parent or any adjournment or postponement thereof, or in connection with any written consent of the stockholders of Parent, with respect to the Merger, the Merger Agreement or any Acquisition Proposal, the Stockholder shall:

(a) appear at such meeting or otherwise cause the Shares and any New Shares (as defined below) to be counted as present thereat for purposes of calculating a quorum;

(b) from and after the date hereof until the Expiration Date, vote (or cause to be voted), or deliver a written consent (or cause a written consent to be delivered) covering all of the Shares and any New Shares that such Stockholder shall be entitled to so vote: (i) in favor of adoption and approval of the Merger Agreement and all other transactions contemplated by the Merger Agreement as to which stockholders of Parent are called upon to vote or consent in favor of any matter necessary for consummation of the Merger and the other transactions contemplated by the Merger Agreement; (ii) against any action or agreement that would result in a breach in any material respect of any covenant,

representation or warranty or any other obligation or agreement of Parent or any of its Subsidiaries or Affiliates under the Merger Agreement or that would reasonably be expected to result in any of the conditions to Parent’s or any of its Subsidiaries or Affiliates’ obligations under the Merger Agreement not being fulfilled; and (iii) against any Acquisition Proposal, or any agreement, transaction or other matter that is intended to, or would reasonably be expected to, impede, interfere with, delay, postpone, discourage or materially and adversely affect the consummation of the Merger and all other transactions contemplated by the Merger Agreement. The Stockholder shall not take or commit or agree to take any action inconsistent with the foregoing.

2. Expiration Date. As used in this Agreement, the term “Expiration Date” shall mean the earlier to occur of (a) the Effective Time, (b) the date that the Merger Agreement shall have been terminated in accordance with the terms and provisions thereof, (c) the date on which Parent’s Board of Directors effects an Adverse Recommendation Change in compliance with Section 6.6(b) of the Merger Agreement, or (d) upon mutual written agreement of the parties to terminate this Agreement. Upon termination or expiration of this Agreement, no party shall have any further obligations or liabilities under this Agreement.

3. Additional Purchases. The Stockholder agrees that any shares of capital stock of Parent that the Stockholder purchases or with respect to which the Stockholder otherwise acquires sole or shared voting power after the execution of this Agreement and prior to the Expiration Date, whether by the exercise of any stock options or otherwise (“New Shares”), shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Shares. The Stockholder agrees to promptly notify Company in writing of the nature and amount of any acquisition of New Shares.

4. Agreement to Retain Shares. From and after the date hereof until the Expiration Date, the Stockholder shall not, directly or indirectly, (a) sell, assign, transfer, tender, or otherwise dispose of (including, without limitation, by the creation of a Lien (as defined in Section 5(c) below)) any Shares or New Shares, (b) deposit any Shares or New Shares into a voting trust or enter into a voting agreement or similar arrangement with respect to such Shares or New Shares or grant any proxy or power of attorney with respect thereto, (c) enter into any contract, option, commitment or other arrangement or understanding with respect to the direct or indirect sale, transfer, assignment or other disposition of (including, without limitation, by the creation of a Lien (as defined in Section 5(c) below)) any Shares or New Shares, or (d) take any action that would make any representation or warranty of Stockholder contained herein untrue or incorrect or have the effect of preventing or disabling Stockholder from performing Stockholder’s obligations under this Agreement. Notwithstanding the foregoing, the Stockholder may make (a) transfers by will or by operation of law or other transfers for estate planning purposes, in which case this Agreement shall bind the transferee, (b) if the Stockholder is a partnership or limited liability company, transfers to one or more partners or members of Stockholder or to an affiliated person under common control with the Stockholder, and (c) as Company may otherwise agree in writing in its sole discretion; provided that a transfer referred to in this sentence shall be permitted only if the transferee agrees in writing to be bound by all of the terms of this Agreement.

5. Representations and Warranties of Stockholder. The Stockholder hereby represents and warrants to Company as follows:

(a) the Stockholder has the full power and authority to execute and deliver this Agreement and to perform Stockholder’s obligations hereunder;

(b) this Agreement (assuming this Agreement constitutes a valid and binding agreement of Company) has been duly executed and delivered by or on behalf of the Stockholder and constitutes a valid and binding agreement with respect to the Stockholder, enforceable against the Stockholder in accordance with its terms, except as enforcement may be limited by general principles of equity whether applied in a court of law or a court of equity and by bankruptcy, insolvency and similar laws affecting creditors’ rights and remedies generally;

(c) the Stockholder beneficially owns the number of Shares indicated opposite such Stockholder’s name on Schedule 1, and will own any New Shares, free and clear of any known liens, claims, charges or other encumbrances or restrictions of any kind whatsoever (other than restrictions under applicable securities laws) (“Liens”), and has sole or shared, and otherwise unrestricted, voting power with respect to such Shares or New Shares and none of the Shares or New Shares are subject to any voting trust or other agreement, arrangement, or restriction with respect to the voting of the Shares or the New Shares, except as contemplated by this Agreement;

(d) the execution and delivery of this Agreement by the Stockholder does not, and the performance by the Stockholder of his, her or its obligations hereunder and the compliance by the Stockholder with any provisions hereof will not, violate or conflict with, result in a material breach of or constitute a default (or an event that with notice or lapse of time or both would become a material default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a Lien on any Shares or New Shares pursuant to, any agreement, instrument, note, bond, mortgage, contract, lease, license, permit or other obligation or any order, arbitration award, judgment or decree to which the Stockholder is a party or by which the Stockholder is bound, or, to the Stockholder’s knowledge, any law, statute, rule or regulation to which the Stockholder is subject or, in the event that the Stockholder is a corporation, partnership, trust or other entity, any bylaw or other organizational document of the Stockholder; and

(e) the execution and delivery of this Agreement by the Stockholder does not, and the performance of this Agreement by the Stockholder does not and will not, require any consent, approval, authorization or permit of, or filing with or notification to, any governmental or regulatory authority by Stockholder except for applicable requirements, if any, of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and except where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not prevent or delay the performance by Stockholder of his or her obligations under this Agreement in any material respect.

6. Irrevocable Proxy. Subject to the last sentence of this Section 6, by execution of this Agreement, the Stockholder does hereby appoint the members of the Board of Directors of Company, and each of them, with full power of substitution and resubstitution, as the Stockholder’s true and lawful attorney and irrevocable proxy, to the fullest extent of the undersigned’s rights with respect to the Shares, to vote, if the Stockholder is unable to perform his, her or its obligations under this Agreement, each of such Shares solely with respect to the matters set forth in Section 1 hereof. The Stockholder intends this proxy to be irrevocable and coupled with an interest hereunder until the Expiration Date and hereby revokes any proxy previously granted by the Stockholder with respect to the Shares. Notwithstanding anything contained herein to the contrary, this irrevocable proxy shall automatically terminate upon the Expiration Date of this Agreement. The Stockholder hereby revokes any proxies previously granted, and represents that none of such previously-granted proxies are irrevocable.

7. No Solicitation. From and after the date hereof until the Expiration Date, the Stockholder shall not, nor shall it permit any of its Subsidiaries or Affiliates to, nor shall it authorize any officer, director or Representative of, the Stockholder or any of its Subsidiaries or Affiliates to, (a) take any action that Parent is prohibited from taking pursuant to Section 6.6(a) of the Merger Agreement, (b) solicit proxies, become a “participant” in a “solicitation” or take any action to facilitate a “solicitation” (as such terms are defined in Regulation 14A under the Exchange Act) with respect to an Acquisition Proposal (other than the Merger Agreement), (c) initiate a stockholders’ vote or action by consent of Parent’s stockholders with respect to an Acquisition Proposal, or (d) except by reason of this Agreement become a member of a “group” (as such term is defined in Section 13(d) of the Exchange Act) with respect to any voting securities of Parent that takes any action in support of an Acquisition Proposal.

8. Waiver of Appraisal Rights. The Stockholder hereby waives, and agrees not to exercise or assert, any appraisal rights under Section 262 of the DGCL in connection with the Merger.

9. No Limitation on Discretion as Director or Fiduciary. Notwithstanding anything herein to the contrary, the covenants and agreements set forth herein shall not prevent the Stockholder, if the Stockholder or any officer, partner, member or employee of the Stockholder or any Affiliate of the Stockholder is serving on the Board of Directors of Parent, from exercising his or her duties and obligations as a director of Parent or otherwise taking any action or omitting to take any action, subject to the applicable provisions of the Merger Agreement, while acting in such capacity as a director of Parent, and no such action taken (or omitted to be taken) by the Stockholder or any officer, partner, member or employee of Stockholder or any Affiliate of Stockholder shall be deemed to constitute a breach or default under any provision of this Agreement. The Stockholder is executing this Agreement solely in his, her or its capacity as a stockholder of Parent.

10. Specific Enforcement. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof or was otherwise breached. It is accordingly agreed that the parties shall be entitled to specific relief hereunder, including, without limitation, an injunction or injunctions to prevent and enjoin breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, in any state or federal court in any competent jurisdiction, in addition to any other remedy to which they may be entitled at law or in equity. Any requirements for the securing or posting of any bond with respect to any such remedy are hereby waived.

11. Further Assurances. The Stockholder shall, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further consents, documents and other instruments as Company may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement.

12. Notice. All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally or sent by overnight courier (providing proof of delivery) to Company in accordance with Section 9.2 of the Merger Agreement and to each Stockholder at its address set forth on Schedule 1 attached hereto (or at such other address for a party as shall be specified by like notice).

13. Severability. If any term or other provision of this Agreement is determined to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

14. Binding Effect and Assignment. All of the covenants and agreements contained in this Agreement shall be binding upon, and inure to the benefit of, the respective parties and their permitted successors, assigns, heirs, executors, administrators and other legal representatives, as the case may be. This Agreement may not be assigned by any party hereto without the prior written consent of the other party hereto.

15. No Waivers. No waivers of any breach of this Agreement extended by Company to the Stockholder shall be construed as a waiver of any rights or remedies of Company with respect to any other stockholder of Parent who has executed an agreement substantially in the form of this Agreement with respect to Shares held or subsequently held by such stockholder or with respect to any subsequent breach of the Stockholder or any other such stockholder of Parent. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

16. Governing Law; Jurisdiction and Venue. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware without regard to its rules of conflict of laws. The parties hereto hereby irrevocably and unconditionally consent to and submit to the exclusive jurisdiction of the courts of the State of Delaware and of the United States of America located in such state (the “Delaware Courts”) for any litigation arising out of or relating to this Agreement and the transactions contemplated hereby (and agree not to commence any litigation relating thereto except in such courts), waive any objection to the laying of venue of any such litigation in the Delaware Courts and agree not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum.

17. Waiver of Jury Trial. The parties hereto hereby waive any right to trial by jury with respect to any action or proceeding related to or arising out of this Agreement, any document executed in connection herewith and the matters contemplated hereby and thereby.

18. No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the Board of Directors of Parent has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of the Parent Certificate, the transactions contemplated by the Merger Agreement, (b) the Merger Agreement is executed by all parties thereto, and (c) this Agreement is executed by all parties hereto.

19. Entire Agreement; Amendment. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto.

20. Effect of Headings. The section headings herein are for convenience only and shall not affect the construction of interpretation of this Agreement.

21. Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed an original but all of which together shall constitute one and the same instrument.

1.1 Annual Meeting. The annual meeting of stockholders shall be held for the election of directors each year at such place, date and time as shall be designated by the Board of Directors. Any other proper business may be transacted at the annual meeting. If no date for the annual meeting is established or said meeting is not held on the date established as provided above, a special meeting in lieu thereof may be held or there may be action by written consent of the stockholders on matters to be voted on at the annual meeting, and such special meeting or written consent shall have for the purposes of these By-laws or otherwise all the force and effect of an annual meeting.

1.2 Special Meetings. Special meetings of stockholders may be called by the Chief Executive Officer, if one is elected, or, if there is no Chief Executive Officer, a President, or by the Board of Directors, but such special meetings may not be called by any other person or persons. The call for the meeting shall state the place, date, hour and purposes of the meeting. Only the purposes specified in the notice of special meeting shall be considered or dealt with at such special meeting.

1.3 Notice of Meetings. Whenever stockholders are required or permitted to take any action at a meeting, a notice stating the place, if any, date and hour of the meeting, the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present and vote at such meeting, and, in the case of a special meeting, the purpose or purposes of the meeting, shall be given by the Secretary (or other person authorized by these By-laws or by law) not less than ten (10) nor more than sixty (60) days before the meeting to each stockholder entitled to vote thereat and to each stockholder who, under the Certificate of Incorporation or under these By-laws is entitled to such notice. If mailed, notice is given when deposited in the mail, postage prepaid, directed to such stockholder at such stockholder’s address as it appears in the records of the Corporation. Without limiting the manner by which notice otherwise may be effectively given to stockholders, any notice to stockholders may be given by electronic transmission in the manner provided in Section 232 of the Delaware General Corporation Law (the “DGCL”).

If a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place, if any, and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such

adjourned meeting are announced at the meeting at which the adjournment is taken, except that if the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

1.4 Quorum. The holders of a majority in interest of all stock issued, outstanding and entitled to vote at a meeting, present in person or represented by proxy, shall constitute a quorum. Any meeting may be adjourned from time to time by a majority of the votes properly cast upon the question, whether or not a quorum is present. The stockholders present at a duly constituted meeting may continue to transact business until adjournment notwithstanding the withdrawal of enough stockholders to reduce the voting shares below a quorum.

1.5 Voting and Proxies. Except as otherwise provided by the Certificate of Incorporation or by law, each stockholder entitled to vote at any meeting of stockholders shall be entitled to one vote for each share of stock held by such stockholder which has voting power upon the matter in question. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for such stockholder by either written proxy or by a transmission permitted by Section 212(c) of the DGCL, but no proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period or is irrevocable and coupled with an interest. Proxies shall be filed with the Secretary of the meeting, or of any adjournment thereof. Except as otherwise limited therein, proxies shall entitle the persons authorized thereby to vote at any adjournment of such meeting.

1.6 Action at Meeting. When a quorum is present, any matter before the meeting shall be decided by vote of the holders of a majority of the shares of stock voting on such matter except where a larger vote is required by law, by the Certificate of Incorporation or by these By-laws. Any election of directors by stockholders shall be determined by a plurality of the votes cast, except where a larger vote is required by law, by the Certificate of Incorporation or by these By-laws. The Corporation shall not directly or indirectly vote any share of its own stock; provided, however, that the Corporation may vote shares which it holds in a fiduciary capacity to the extent permitted by law.

1.7 Presiding Officer. Meetings of stockholders shall be presided over by the Chairman of the Board, if one is elected, or in his or her absence, the Vice Chairman of the Board, if one is elected, or if neither is elected or in their absence, a President. The Board of Directors shall have the authority to appoint a temporary presiding officer to serve at any meeting of the stockholders if the Chairman of the Board, the Vice Chairman of the Board or a President is unable to do so for any reason.

1.8 Conduct of Meetings. The Board of Directors may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board of Directors, the presiding officer of any meeting of stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the presiding officer of

the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present; (iii) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the chairman of the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (v) limitations on the time allotted to questions or comments by participants. Unless and to the extent determined by the Board of Directors or the presiding officer of the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure.

1.9 Action without a Meeting. Unless otherwise provided in the Certificate of Incorporation, any action required or permitted by law to be taken at any annual or special meeting of stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to its registered office, by hand or by certified mail, return receipt requested, or to the Corporation’s principal place of business or to the officer of the Corporation having custody of the minute book. Every written consent shall bear the date of signature and no written consent shall be effective unless, within sixty (60) days of the earliest dated consent delivered pursuant to these By-laws, written consents signed by a sufficient number of stockholders entitled to take action are delivered to the Corporation in the manner set forth in these By-laws. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

1.10 Stockholder Lists. The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Nothing contained in this Section 10 shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten (10) days prior to the meeting in the manner provided by law. The list shall also be open to the examination of any stockholder during the whole time of the meeting as provided by law.

ARTICLE II Directors

2.1 Powers. The business of the Corporation shall be managed by or under the direction of a Board of Directors who may exercise all the powers of the Corporation except as otherwise provided by law, by the Certificate of Incorporation or by these By-laws. In the event of a vacancy in the Board of Directors, the remaining directors, except as otherwise provided by law, may exercise the powers of the full Board until the vacancy is filled.

2.2 Number and Qualification. Unless otherwise provided in the Certificate of Incorporation or in these By-laws, the number of directors which shall constitute the whole board shall be determined from time to time by resolution of the Board of Directors. Directors need not be stockholders.

2.3 Vacancies; Reduction of Board. A majority of the directors then in office, although less than a quorum, or a sole remaining Director, may fill vacancies in the Board of Directors occurring for any reason and newly created directorships resulting from any increase in the authorized number of directors. In lieu of filling any vacancy, the Board of Directors may reduce the number of directors.

2.4 Tenure. Except as otherwise provided by law, by the Certificate of Incorporation or by these By-laws, directors shall hold office until their successors are elected and qualified or until their earlier resignation or removal. Any director may resign at any time upon notice given in writing or by electronic transmission to the Corporation. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event.

2.5 Removal. To the extent permitted by law, a director may be removed from office with or without cause by vote of the holders of a majority of the shares of stock entitled to vote in the election of directors.

2.6 Meetings. Regular meetings of the Board of Directors may be held without notice at such time, date and place as the Board of Directors may from time to time determine. Special meetings of the Board of Directors may be called, orally or in writing, by the Chief Executive Officer, if one is elected, or, if there is no Chief Executive Officer, the President, or by two or more Directors, designating the time, date and place thereof. Directors may participate in meetings of the Board of Directors by means of conference telephone or other communications equipment by means of which all directors participating in the meeting can hear each other, and participation in a meeting in accordance herewith shall constitute presence in person at such meeting.

2.7 Notice of Meetings. Notice of the time, date and place of all special meetings of the Board of Directors shall be given to each director by the Secretary, or Assistant Secretary, or in case of the death, absence, incapacity or refusal of such persons, by the officer or one of the directors calling the meeting.

2.8 Quorum. At any meeting of the Board of Directors, a majority of the total number of directors shall constitute a quorum for the transaction of business. Less than a quorum may adjourn any meeting from time to time and the meeting may be held as adjourned without further notice.

2.9 Action at Meeting. At any meeting of the Board of Directors at which a quorum is present, unless otherwise provided in the following sentence, a majority of the directors present may take any action on behalf of the Board of Directors, unless a larger number is

required by law, by the Certificate of Incorporation or by these By-laws. So long as there are two (2) or fewer Directors, any action to be taken by the Board of Directors shall require the approval of all Directors.

2.10 Action by Consent. Any action required or permitted to be taken at any meeting of the Board of Directors may be taken without a meeting if all members of the Board of Directors consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the records of the meetings of the Board of Directors. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

2.11 Committees. The Board of Directors may, by resolution passed by a majority of the whole Board of Directors, establish one or more committees, each committee to consist of one or more directors. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member.

Any such committee, to the extent permitted by law and to the extent provided in the resolution of the Board of Directors, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to the following: (i) approving or adopting, or recommending to the stockholders, any action or matter expressly required by the DGCL to be submitted to stockholders for approval or (ii) adopting, amending or repealing any provision of these By-laws.

Except as the Board of Directors may otherwise determine, any such committee may make rules for the conduct of its business, but in the absence of such rules its business shall be conducted so far as possible in the same manner as is provided in these By-laws for the Board of Directors. All members of such committees shall hold their committee offices at the pleasure of the Board of Directors, and the Board may abolish any committee at any time.

Such certificate shall be signed by a President or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary. Such signatures may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed on such certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if such person were such officer, transfer agent or registrar at the time of its issue. Every certificate for shares of stock which are subject to any restriction on transfer and every certificate issued when the Corporation is authorized to issue more than one class or series of stock shall contain such legend with respect thereto as is required by law. The Corporation shall be permitted to issue fractional shares.

4.2 Transfers. Subject to any restrictions on transfer, shares of stock may be transferred on the books of the Corporation by the surrender to the Corporation or its transfer

agent of the certificate therefor properly endorsed or accompanied by a written assignment or power of attorney properly executed, with transfer stamps (if necessary) affixed, and with such proof of the authenticity of signature as the Corporation or its transfer agent may reasonably require.

4.3 Record Holders. Except as may otherwise be required by law, by the Certificate of Incorporation or by these By-laws, the Corporation shall be entitled to treat the record holder of stock as shown on its books as the owner of such stock for all purposes, including the payment of dividends and the right to vote with respect thereto, regardless of any transfer, pledge or other disposition of such stock, until the shares have been transferred on the books of the Corporation in accordance with the requirements of these By-laws.

It shall be the duty of each stockholder to notify the Corporation of such stockholder’s post office address.

4.4 Record Date. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a record date, which shall not precede the date on which it is established, and which shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting, more than ten (10) days after the date on which the record date for stockholder consent without a meeting is established, nor more than sixty (60) days prior to any other action. In such case only stockholders of record on such record date shall be so entitled notwithstanding any transfer of stock on the books of the Corporation after the record date.

If no record date is fixed, (a) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held, (b) the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is necessary, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in this state, to its principal place of business, or to an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded, and (c) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

Notwithstanding the foregoing, “Corporate Status” shall not include the status of a person who is serving or has served as a director, officer, employee or agent of a constituent corporation absorbed in a merger or consolidation transaction with the Corporation with respect to such person’s activities prior to said transaction, unless specifically authorized by the Board of Directors or the stockholders of the Corporation;

5.2 Indemnification of Directors and Officers. Subject to the operation of Section 4 of this Article V of these By-laws, each Director and Officer shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment) against any and all Expenses, judgments, penalties, fines and amounts reasonably paid in settlement that are incurred by such Director or Officer or on such Director’s or Officer’s behalf in connection with any threatened, pending or completed Proceeding or any claim, issue or matter therein, which such Director or Officer is, or is threatened to be made, a party to or participant in by reason of such Director’s or Officer’s Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 2 shall continue as to a Director or Officer after he or she has ceased to be a Director or Officer and shall inure to the benefit of his or her heirs, executors, administrators and personal representatives. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by such Director or Officer only if such Proceeding was authorized by the Board of Directors of the Corporation, unless such Proceeding was brought to enforce an Officer or Director’s rights to indemnification or, in the case of Directors, advancement of Expenses under these By-laws in accordance with the provisions set forth herein.

5.3 Indemnification of Non-Officer Employees. Subject to the operation of Section 4 of this Article V of these By-laws, each Non-Officer Employee may, in the discretion of the Board of Directors of the Corporation, be indemnified by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses, judgments, penalties, fines and amounts reasonably paid in settlement that are incurred by such Non-Officer Employee or on such Non-Officer Employee’s behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee’s Corporate Status, if such Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal representatives, executors and administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such Non-Officer Employee only if such Proceeding was authorized by the Board of Directors of the Corporation.

5.4 Good Faith. Unless ordered by a court, no indemnification shall be provided pursuant to this Article V to a Director, to an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. Such determination shall be made by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board of Directors, (b) a committee comprised of Disinterested Directors, such committee having been designated by a majority vote of the Disinterested Directors (even though less than a quorum), (c) if there are no such Disinterested Directors, or if a majority of Disinterested Directors so directs, by independent legal counsel in a written opinion, or (d) by the stockholders of the Corporation.

5.5 Advancement of Expenses to Directors Prior to Final Disposition.

(a) The Corporation shall advance all Expenses incurred by or on behalf of any Director in connection with any Proceeding in which such Director is involved by reason of such Director’s Corporate Status within ten (10) days after the receipt by the Corporation of a written statement from such Director requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Director and shall be preceded or accompanied by an undertaking by or on behalf of such Director to repay any Expenses so advanced if it shall ultimately be determined that such Director is not entitled to be indemnified against such Expenses.

(b) If a claim for advancement of Expenses hereunder by a Director is not paid in full by the Corporation within 10 days after receipt by the Corporation of documentation of Expenses and the required undertaking, such Director may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and if successful in whole or in part, such Director shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article V shall not be a defense to the action and shall not create a presumption that such advancement is not permissible. The burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation.

(c) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Director has not met any applicable standard for indemnification set forth in the DGCL.

5.6 Advancement of Expenses to Officers and Non-Officer Employees Prior to Final Disposition.

(a) The Corporation may, at the discretion of the Board of Directors of the Corporation, advance any or all Expenses incurred by or on behalf of any Officer and Non-Officer Employee in connection with any Proceeding in which such is involved by reason of the

Corporate Status of such Officer or Non-Officer Employee upon the receipt by the Corporation of a statement or statements from such Officer or Non-Officer Employee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer and Non-Officer Employee and shall be preceded or accompanied by an undertaking by or on behalf of such to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified against such Expenses.

(b) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Officer or Non-Officer Employee has not met any applicable standard for indemnification set forth in the DGCL.

5.7 Contractual Nature of Rights.

(a) The foregoing provisions of this Article V shall be deemed to be a contract between the Corporation and each Director and Officer entitled to the benefits hereof at any time while this Article V is in effect, and any repeal or modification thereof shall not affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any Proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts.

(b) If a claim for indemnification hereunder by a Director or Officer is not paid in full by the Corporation within 60 days after receipt by the Corporation of a written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such indemnification under this Article V shall not be a defense to the action and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation.

(c) In any suit brought by a Director or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Director or Officer has not met any applicable standard for indemnification set forth in the DGCL.

5.8 Non-Exclusivity of Rights. The rights to indemnification and advancement of Expenses set forth in this Article V shall not be exclusive of any other right which any Director, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Certificate or these By-laws, agreement, vote of stockholders or Disinterested Directors or otherwise.

5.9 Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer

Employee, or arising out of any such person’s Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article V.

5.10 Other Indemnification. The Corporation’s obligation, if any, to indemnify any person under this Article V as a result of such person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise.

Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any meeting needs to be specified in any written waiver or any waiver by electronic transmission.
