Capitalized terms used herein and not defined herein shall have the meanings assigned to such terms in Annex A attached hereto.

PRELIMINARY STATEMENT

WHEREAS, the Company and Holdings have entered into a Technology License Agreement pursuant to which the Company has granted Holdings an exclusive license (the “License”) to the use of certain intellectual property related to the Programs owned or controlled by the Company;

WHEREAS, contemporaneously with the execution of this Agreement, the Company, Holdings and the Symphony Collaboration are entering into a Novated and Restated Technology License Agreement, pursuant to which, among other things, Holdings will assign by way of novation the License to the Symphony Collaboration;

WHEREAS, the Company and Holdings have entered into a Research and Development Agreement pursuant to which Holdings and the Company have agreed to develop the Programs and to establish a Development Committee to oversee such development;

WHEREAS, contemporaneously with the execution of this Agreement, the Company, Holdings and the Symphony Collaboration are entering into an Amended and Restated Research and Development Agreement, pursuant to which, among other things, Holdings will assign its rights and obligations under the Research and Development Agreement to the Symphony Collaboration;

WHEREAS, contemporaneously with the execution of this Agreement, in order to fund such research and development, institutional investors are committing to invest up to $40,000,000 in Holdings (the “Financing”) in exchange for (i) membership interests in Holdings, (ii) shares of the Company Common Stock having a market value of up to $15,000,000 issued to Holdings (the “Direct Investment Shares”), (iii) a warrant to purchase Company Common Stock issued to Holdings (the “Warrant Shares”) having a market value of up to $15,000,000 less the value of the Direct Investment Shares (the “Direct Investment Warrant”), (iv) shares of the Company Common Stock having a market value of $4,000,000 (the “Option Premium Shares”), and (v) other consideration as contemplated by the terms of the Additional Funding Agreement, and Holdings will agree to contribute $15,000,000 of the proceeds of the Financing to the Symphony Collaboration and pay $15,000,000 of the proceeds of the Financing to the Company;

WHEREAS, Holdings desires, in consideration for the foregoing, to grant the Company an option to purchase all of the Common Stock of the Symphony Collaboration and any other Equity Securities issued by the Symphony Collaboration (together, the

“Symphony Collaboration Equity Securities”) owned, or hereinafter acquired, by Holdings on the terms described in this Agreement;

WHEREAS, the Company, Holdings, Investors and the Symphony Collaboration have entered into the Additional Funding Agreement in furtherance of the transactions contemplated hereby and in the other Operative Documents; and

WHEREAS, the Company, the Symphony Collaboration and Holdings have determined that it is in each of its best interest to perform and comply with certain agreements and covenants relating to each of its ongoing operations contained in this Agreement.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto (the “Parties”) agree as follows:

Section 1. Grant of Purchase Option.

(a) Holdings hereby grants to the Company an exclusive irrevocable option (the “Purchase Option”) to purchase all, but not less than all, of the outstanding Symphony Collaboration Equity Securities owned or hereinafter acquired by Holdings, in accordance with the terms of this Agreement.

(b) The Symphony Collaboration hereby covenants and agrees that all Symphony Collaboration Equity Securities issued by the Symphony Collaboration at any time prior to the expiration of the Term (including to Holdings, on, prior to, or after the date hereof or to any other Person at any time whatsoever, in all cases prior to the expiration of the Term) shall be subject to the Purchase Option and all of the other terms and conditions of this Agreement without any additional action on the part of the Company or Holdings. For the avoidance of doubt, to the extent the Symphony Collaboration shall issue any Symphony Collaboration Equity Securities (including any issuance in respect of a transfer of Symphony Collaboration Equity Securities by any holder thereof, including Holdings) after the date hereof to any Person (including Holdings) (any issuance of such Symphony Collaboration Equity Securities being subject to the prior written consent of the Company as set forth in Sections 5(c) and 7(b) hereof, as applicable), the Symphony Collaboration hereby covenants and agrees that it shall cause such Symphony Collaboration Equity Securities to be subject to the Purchase Option without the payment of, or any obligation to pay, any additional consideration in respect of such Symphony Collaboration Equity Securities by the Company, the Symphony Collaboration or any Symphony Collaboration Subsidiary to the Person(s) acquiring such subsequently issued Symphony Collaboration Equity Securities, the Parties acknowledging and agreeing that the sole consideration payable by the Company pursuant to this Agreement for all of the outstanding Symphony Collaboration Equity Securities now or hereinafter owned by any Person shall be the Purchase Price (as defined in Section 2(b) hereof).

(i) The Purchase Option may only be exercised for the purchase of all, and not less than all, of the Symphony Collaboration Equity Securities;

(ii) The Purchase Option may only be exercised a single time;

(iii) Except as expressly provided in Section 1(c)(iv), the Purchase Option may be exercised only during the period (the “Purchase Option Period”) commencing on and including the first day following the first anniversary of the Closing Date (the “Purchase Option Commencement Date”) and ending on and including the earliest of (x) March 31, 2012 (the “Final Termination Date”), (y) the 40th calendar day (such 40th calendar day, the “Funds Termination Date”) immediately following the date (the “Balance Sheet Deficiency Date”) on which a notice that an impending Funds Termination Date may occur as a result of such Balance Sheet Deficiency Date (the “Funds Termination Notice”) is delivered to the Company by Holdings or the Symphony Collaboration in accordance with Section 13 hereof, accompanied by an internally prepared, unaudited balance sheet of the Symphony Collaboration (prepared in accordance with GAAP (except for the absence of footnotes)) stating that the working capital of the Symphony Collaboration is less than the Balance Sheet Deficiency Threshold at such time (the “Balance Sheet Deficiency”); provided, that, notwithstanding the foregoing to the contrary, if the Additional Holdings Funding, a contribution by the Company pursuant to the Optional Company Funding or the Company Payment Amount shall have been paid to the Symphony Collaboration, the Funds Termination Date shall be the 30th calendar day immediately following the next occurrence of a Balance Sheet Deficiency Date, and (z) the date on which both Programs have been discontinued pursuant to Section 4.2(c) of the Amended and Restated Research and Development Agreement.

(iv) In the event that the Symphony Collaboration terminates the Amended and Restated Research and Development Agreement pursuant to Section 17.2 thereof, the Company shall have five (5) Business Days to notify Holdings of its exercise of the Purchase Option under the terms of this Agreement.

Section 2. Exercise of Purchase Option.

(a) Exercise Notice. The Company may exercise the Purchase Option only by delivery of a notice in the form attached hereto as Exhibit 1 (the “Purchase Option Exercise Notice”) during the Purchase Option Period. The Purchase Option Exercise Notice shall be delivered on a Business Day to Holdings and the Symphony Collaboration and shall be irrevocable once delivered. The date on which the Purchase Option Exercise Notice is first delivered to Holdings and the Symphony Collaboration is referred to as the “Purchase Option Exercise Date.” The Purchase Option Exercise Notice shall contain (1) an estimated date for the settlement of the Purchase Option (the “Purchase Option Closing”), which date shall be estimated in

accordance with this Section 2(a), (2) the Purchase Price, determined in accordance with Section 2(b) hereof, and (3) if the Company intends to pay part of the Purchase Price in Company Common Stock pursuant to a convertible note, the form of which is attached hereto as Annex B (the “Convertible Note”), notice of such intent, the estimated number of shares to be transferred at such purchase price, the estimated valuation thereof and the percentage such portion bears to (A) the Purchase Price, and (B) the total amount of the Company Common Stock then issued and outstanding (which shall be no greater percentages than are permitted under Section 2(c)). If, during the period following the delivery of the Purchase Option Exercise Notice, the working capital held by the Symphony Collaboration is less than or equal to the Balance Sheet Deficiency Threshold, then the Symphony Collaboration shall cease payment of any amounts owed to the Company in respect of its activities pursuant to the Amended and Restated Research and Development Agreement, but shall continue to pay amounts owed to all other Persons. All cash and cash equivalents on the Symphony Collaboration’s balance sheet on the date of the Purchase Option Closing (the “Purchase Option Closing Date”) will not be transferred or distributed to Holdings and shall be retained by the Symphony Collaboration. The Purchase Option Closing Date shall be as follows:

(i) If the Company elects to pay the entire Purchase Price in cash, the Purchase Option Closing Date shall be the date that is the later of: (A) five (5) Business Days following the Purchase Option Exercise Date; and (B) five (5) Business Days following the date that the Company receives all necessary Government Approvals related to its HSR Filings; provided, however that unless Holdings receives from the Company an opinion from nationally recognized anti-trust counsel (which opinion is acceptable in form and substance to Holdings) to the effect that no HSR Filings are required, the Company and Holdings shall make all necessary HSR Filings within ten (10) Business Days following the Purchase Option Exercise Date and shall promptly and diligently pursue the related regulatory process, including without limitation, responding to any second request from the Federal Trade Commission or the Department of Justice, as applicable; and provided, further, that (1) if there is no second request from the Federal Trade Commission or the Department of Justice, as applicable, with respect to the Company’s or Holdings’ HSR Filings, then in no event shall the Purchase Option Closing Date be more than sixty (60) days following the Purchase Option Exercise Date, and (2) if there is a second request from the Federal Trade Commission or the Department of Justice, as applicable, with respect to the Company’s or Holdings’ HSR Filings, then in no event shall the Purchase Option Closing Date be more than one hundred and twenty (120) days following the date upon which the later of the Company or Holdings delivers documents pursuant to such second request. If the Company shall fail to make such cash payment on the Purchase Option Closing Date within the applicable time period set forth above, then in addition to any other rights that Holdings shall have hereunder, this Agreement shall terminate and the Company shall relinquish all rights hereunder to purchase Symphony Collaboration Equity Securities; or

(ii) If the Company elects to pay a portion of the Purchase Price in Company Common Stock pursuant to the Convertible Note (subject to the limitations set forth herein and in the Registration Rights Agreement), the Purchase Option Closing Date shall be the date that is the latest of:

(A) five (5) Business Days following the Purchase Option Exercise Date;

(B) five (5) Business Days following the Effective Registration Date of such Company Common Stock; provided, that Company shall file the Registration Statement contemplated by Section 3(b)(i) within (x) ten (10) Business Days after the Purchase Option Exercise Date if the Company is eligible to use Form S-3 under the Securities Act (or any successor form), or (y) twenty (20) Business Days after the Purchase Option Exercise Date if the Company is not eligible to use Form S-3 under the Securities Act (or any successor form), unless otherwise agreed;

(C) five (5) Business Days following the date that the Company receives the necessary Government Approvals related to its HSR Filings (if any) related to the exercise of the Purchase Option; provided, however, that the Company and Holdings shall make all necessary HSR Filings within five (5) Business Days following the Purchase Option Exercise Date and shall promptly and diligently pursue the related regulatory process consistent with the provisos in clause (i) above; and

(D) the maturity date set forth in the Convertible Note.

provided, further, that the Company shall use commercially reasonable efforts to have such Registration Statement declared effective by the SEC as promptly as possible following the filing of the Registration Statement. The Company shall use commercially reasonable efforts to maintain the effectiveness of any such Registration Statement for a period of two (2) years following the SEC’s declaration. Subject to the last sentence of this clause (a), in the event that such Registration Statement is not declared effective within one hundred and twenty (120) days following the Purchase Option Exercise Date (such period, the “Declaration Period”), the Company shall pay the full Purchase Price in cash within five (5) Business Days (in which event the Purchase Option Closing Date shall be the date upon which such cash payment within five (5) Business Days is made by the Company). If the Company shall fail to make such cash payment, then in addition to any other rights or remedies that Holdings shall have arising from such breach, this Agreement shall terminate and the Company shall relinquish all rights hereunder to purchase the Symphony Collaboration Equity Securities. The Declaration Period shall be extended for a reasonable period of time as determined by the Symphony Collaboration Board in consultation with recognized securities counsel in the event that any member of the Investors takes action with respect to the Company Common Stock that prevents the Registration Statement from being declared effective during the Declaration Period.

(b) Purchase Price Upon Option Exercise. Upon exercise of the Purchase Option and as complete and full consideration for the sale to the Company by Holdings of its Symphony Collaboration Equity Securities (and for Symphony Collaboration Equity Securities of any other Person), the Company shall pay (i) two (2) times the aggregate amount of the Initial Investors Funding and the Additional Holdings

Funding, minus (ii) (x) the aggregate amount of all Discontinuation Prices and other amounts paid by the Company directly to Holdings or to the Symphony Collaboration pursuant to Section 11(a) of the Amended and Restated Research and Development Agreement and the aggregate amount of all Discontinued Funds, in each case as subsequently dividended or otherwise distributed to Holdings (if any), (y) any amount paid by the Company for Symphony Collaboration Equity Securities of any other Person and (z) 50% of the purchase price paid in consideration for any Non-IV Shares (the “Purchase Price”).

(c) Form of Payment. Subject to Sections 2(a) and 2(e), the Purchase Price may be paid in either cash or a combination of cash and the Convertible Note, at the sole discretion of the Company; provided, that, in no event may the value of Company Common Stock (determined in accordance with Section 2(e) hereof) delivered pursuant to the Convertible Note in connection with the exercise of the Purchase Option constitute more than (i) 20% of the total Purchase Price or (ii) 10% of the total Company Common Stock outstanding immediately prior to the time of the Purchase Option Exercise Date; provided further, that, if the Company elects to pay the Purchase Price in a combination of cash and the Convertible Note, the cash portion must be paid in accordance with Section 2(a)(i); provided, however, that unless otherwise agreed by the Parties, the payment of a portion of the Purchase Price in Company Common Stock pursuant to the Convertible Note shall be subject to the receipt of any necessary stockholder approval for the purposes of the NASDAQ Marketplace Rules 4350(i)(1)(B) and 4350(i)(1)(D); and further, in the sole discretion of Holdings, shall not be permitted if such payment would or would be reasonably likely to result in any liability to the Investors or their Affiliates under Section 16 of the Securities Exchange Act of 1934, as amended, as a result of any transaction entered into by the Investors or any of their Affiliates prior to the issuance of such shares of Company Common Stock.

(d) Surrender of Symphony Collaboration Equity Securities; Symphony Collaboration Board. Subject to the terms and conditions of this Agreement, on the Purchase Option Closing Date, Holdings shall surrender to the Company its certificates representing its Symphony Collaboration Equity Securities, and shall convey good title to such Symphony Collaboration Equity Securities, free from any Encumbrances and from any and all restrictions that any sale, assignment or other transfer of such Symphony Collaboration Equity Securities be consented to or approved by any Person. On or prior to the Purchase Option Closing Date, Holdings shall remove all directors serving on the Symphony Collaboration Board, other than the Company Director (as defined in Section 4(b)(v) hereof), as of the Purchase Option Closing Date.

(e) Valuation of Company Stock. In the event that the Company elects to pay part of the Purchase Price through the delivery to Holdings of Company Common Stock, the value per share thereof (the “Company Common Stock Valuation”) shall equal the average closing price of Company Common Stock, as reported by the NASDAQ Global Market, or other national exchange that is the primary exchange on which Company Common Stock is then listed, for the thirty (30) trading days immediately preceding (but not including) the second trading day prior to the Purchase Option Closing Date. If Company Common Stock is not then traded on a

national exchange or the NASDAQ Global Market, unless otherwise agreed by the Parties, then the Company shall be obligated to pay the Purchase Price solely in cash on the Purchase Option Closing Date. The Company shall calculate the Company Common Stock Valuation in accordance with this Section 2(e), subject to review and confirmation by Holdings.

(f) Share Certificates. Any stock certificate(s) issued by the Company for Company Common Stock pursuant to this Section 2 may contain a legend (the “33 Act Legend”) substantially as follows:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE, AND THE SAME HAVE BEEN ISSUED IN RELIANCE ON EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND SUCH LAWS. SUCH SHARES MAY NOT BE SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT AS PERMITTED UNDER SUCH SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM.

This legend shall be removed by the Company, subject to, and in accordance with, the terms of Section 3(b)(iii) hereof.

(g) Government Approvals. On or prior to the Purchase Option Closing Date, each of the Company, the Symphony Collaboration and Holdings shall have taken all necessary action to cause all Governmental Approvals with respect to such Party (including, without limitation, the preparing and filing of any pre-merger notification and report forms required under the HSR Filings required to be in effect in connection with the transactions contemplated by this Agreement to be in effect; provided, however, that with respect to Government Approvals required by a Governmental Authority other than the United States federal government and its various branches and agencies, the Parties’ obligations under this Section 2(g) shall be limited to causing to be in effect only those Government Approvals, the failure of which to be in effect would, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on any of the Parties. Each of the Symphony Collaboration and the Company shall pay its own costs associated with taking such action. The Symphony Collaboration shall pay any costs of Holdings associated with obtaining Government Approvals required in connection with the exercise of the Purchase Option. All other costs and expenses of Holdings shall be paid by Holdings pursuant to Section 8(b) hereof, including any costs arising from any error in Holdings’ initial valuation of its investment in the Symphony Collaboration.

(h) Transfer of Title. Transfer of title to the Company of all of the Symphony Collaboration Equity Securities shall be deemed to occur automatically on the Purchase Option Closing Date, subject to the payment by the Company on such date

of the Purchase Price and its performance of its other obligations herein required to be performed under Section 2(e) and (f), and under the Registration Rights Agreement, as applicable, on or prior to the Purchase Option Closing Date to the reasonable satisfaction of Holdings, and thereafter the Symphony Collaboration shall treat the Company as the sole holder of all Symphony Collaboration Equity Securities, notwithstanding any failure of Holdings to tender certificates representing such shares to the Company in accordance with Section 2(d) hereof. After the Purchase Option Closing Date, Holdings shall have no rights in connection with such Symphony Collaboration Equity Securities other than the right to receive the Purchase Price; provided, however, that nothing in this Section 2(h) shall affect the survivability of any indemnification provision in this Agreement upon termination of this Agreement.

(i) Consents and Authorizations. On or prior to the Purchase Option Closing Date, the Company shall have obtained all consents and authorizations necessary from stockholders and/or its board of directors for the consummation of the exercise and closing of the Purchase Option, as may be required under the organizational documents of the Company, any prior stockholders or board resolution, any stock exchange or similar rules or any applicable law.

Section 2A. Change of Control; Put Option.

(a) In the event that a Change of Control of the Company occurs, the Company shall, and as applicable, shall cause the Surviving Entity to, (i) subject to the terms of the Confidentiality Agreement and any confidentiality agreement entered into in connection with a Change of Control, provide notice to Holdings of a Change of Control no more than ten (10) days after the execution of a definitive agreement committing the Company to a Change of Control, and in any event, no less than ten (10) days prior to the closing of such Change of Control transaction, (ii) promptly following any Change of Control, if the Company is not the Surviving Entity, the Surviving Entity shall execute and deliver to the Symphony Collaboration and Holdings instruments, in form and substance reasonably acceptable to the Symphony Collaboration and Holdings, whereby the Surviving Entity expressly assumes all of the obligations of the Company hereunder and under each other Operative Document to which the Company is a party, and (iii) ensure that all material applications and filings have been made to, and all material consents have been received from, the FDA, and any applicable foreign equivalent thereof, necessary for the Surviving Entity to satisfy all of its material obligations under the Operative Documents, except to the extent that failure to make such applications or filings or receive such consents would not reasonably be expected to have a material adverse effect on the Programs or the Symphony Collaboration’s rights under the Operative Documents.

(b) Holdings shall have an exclusive option (the “Change of Control Put Option”) to sell 100% of the Symphony Collaboration Equity Securities to the Surviving Entity, which may be exercised within 30 days following a Change of Control, but in any event prior to the expiration of the Term, in its sole discretion following a Change of Control with respect to the Company.

(c) Holdings may exercise the Change of Control Put Option only by delivery of written notice (the “Change of Control Put Option Exercise Notice”) during the Purchase Option Period. The Change of Control Put Option Exercise Notice shall be delivered on a Business Day to the Surviving Entity and the Symphony Collaboration, and shall thereafter be deemed for all purposes under the terms of this Agreement to be a Purchase Option Exercise Notice by the Surviving Entity (in accordance with the provisions of Section 2 hereof) as of the date such notice is delivered (such date to be deemed for all purposes under the terms of this Agreement as the Purchase Option Exercise Date). The Purchase Price with respect to such an exercise of the Change of Control Put Option shall be the Purchase Price applicable under Section 2(b) hereof, payable solely in cash. In the event Holdings exercises the Change of Control Put Option and such sale is consummated, Holdings shall maintain and does not release any rights or claims against the Surviving Entity, including rights or claims whereby Holdings is otherwise entitled to reimbursement or indemnification under any of the Operative Documents or any other document delivered by the Surviving Entity in connection with such Change of Control.

To the extent that the foregoing undertaking by the Company or Holdings may be unenforceable for any reason, such Party shall make the maximum contribution to the payment and satisfaction of any Loss that is permissible under applicable law.

(c) Notice of Claims. Any Indemnified Party that proposes to assert a right to be indemnified under this Section 10 shall notify the Company or Holdings, as applicable (the “Indemnifying Party”), promptly after receipt of notice of commencement of any action, suit or proceeding against such Indemnified Party (an “Indemnified Proceeding”) in respect of which a claim is to be made under this Section 10, or the incurrence or realization of any Loss in respect of which a claim is to

be made under this Section 10, of the commencement of such Indemnified Proceeding or of such incurrence or realization, enclosing a copy of all relevant documents, including all papers served and claims made, but the omission to so notify the applicable Indemnifying Party promptly of any such Indemnified Proceeding or incurrence or realization shall not relieve (x) such Indemnifying Party from any liability that it may have to such Indemnified Party under this Section 10 or otherwise, except, as to such Indemnifying Party’s liability under this Section 10, to the extent, but only to the extent, that such Indemnifying Party shall have been prejudiced by such omission, or (y) any other indemnitor from liability that it may have to any Indemnified Party under the Operative Documents.

(d) Defense of Proceedings. In case any Indemnified Proceeding shall be brought against any Indemnified Party, it shall notify the applicable Indemnifying Party of the commencement thereof as provided in Section 10(c), and such Indemnifying Party shall be entitled to participate in, and provided such Indemnified Proceeding involves a claim solely for money damages and does not seek an injunction or other equitable relief against the Indemnified Party and is not a criminal or regulatory action, to assume the defense of, such Indemnified Proceeding with counsel reasonably satisfactory to such Indemnified Party. After notice from such Indemnifying Party to such Indemnified Party of such Indemnifying Party’s election so to assume the defense thereof and the failure by such Indemnified Party to object to such counsel within five (5) Business Days following its receipt of such notice, such Indemnifying Party shall not be liable to such Indemnified Party for legal or other expenses related to such Indemnified Proceedings incurred after such notice of election to assume such defense except as provided below and except for the reasonable costs of investigating, monitoring or cooperating in such defense subsequently incurred by such Indemnified Party reasonably necessary in connection with the defense thereof. Such Indemnified Party shall have the right to employ its own counsel in any such Indemnified Proceeding, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless:

(i) the employment of counsel by such Indemnified Party at the expense of the applicable Indemnifying Party has been authorized in writing by such Indemnifying Party;

(ii) such Indemnified Party shall have reasonably concluded in its good faith (which conclusion shall be determinative unless a court determines that such conclusion was not reached reasonably and in good faith) that there is or may be a conflict of interest between the applicable Indemnifying Party and such Indemnified Party in the conduct of the defense of such Indemnified Proceeding or that there are or may be one or more different or additional defenses, claims, counterclaims, or causes of action available to such Indemnified Party (it being agreed that in any case referred to in this clause (ii) such Indemnifying Party shall not have the right to direct the defense of such Indemnified Proceeding on behalf of the Indemnified Party);

(iii) the applicable Indemnifying Party shall not have employed counsel reasonably acceptable to the Indemnified Party, to assume the defense of such Indemnified Proceeding within a reasonable time after notice of the

commencement thereof; provided, however, that (A) this clause (iii) shall not be deemed to constitute a waiver of any conflict of interest that may arise with respect to any such counsel, and (B) an Indemnified Party may not invoke this clause (iii) if such Indemnified Party failed to timely object to such counsel pursuant to the first paragraph of this Section 10(d) above (it being agreed that in any case referred to in this clause (iii) such Indemnifying Party shall not have the right to direct the defense of such Indemnified Proceeding on behalf of the Indemnified Party); or

(iv) any counsel employed by the applicable Indemnifying Party shall fail to timely commence or reasonably conduct the defense of such Indemnified Proceeding and such failure has prejudiced (or is in immediate danger of prejudicing) the outcome of such Indemnified Proceeding (it being agreed that in any case referred to in this clause (iv) such Indemnifying Party shall not have the right to direct the defense of such Indemnified Proceeding on behalf of the Indemnified Party);

in each of which cases the reasonable fees and expenses of counsel for such Indemnified Party shall be at the expense of such Indemnifying Party. The Indemnifying Person shall be responsible for the reasonable fees and expenses of only one counsel retained by all Indemnified Parties with respect to any Indemnified Proceeding, and any additional counsel shall be retained at the expense of such Indemnified Party, unless counsel for any Indemnified Party reasonably concludes in good faith (which conclusion shall be determinative unless a court determines that such conclusion was not reached reasonably and in good faith) that there is or may be a conflict of interest between such Indemnified Party and one or more other Indemnified Parties in the conduct of the defense of such Indemnified, in which case the Indemnifying Party shall be responsible for the reasonable fees and expenses of such additional counsel.

(e) Settlement. Without the prior written consent of such Indemnified Party, such Indemnifying Party shall not settle or compromise, or consent to the entry of any judgment in, any pending or threatened Indemnified Proceeding, unless such settlement, compromise, consent or related judgment (i) includes an unconditional release of such Indemnified Party from all liability for Losses arising out of such claim, action, investigation, suit or other legal proceeding, (ii) provides for the payment of money damages as the sole relief for the claimant (whether at law or in equity), (iii) involves no admission of fact adverse to the Indemnified Party or finding or admission of any violation of law or the rights of any Person by the Indemnified Party, and (iv) is not in the nature of a criminal or regulatory action. No Indemnified Party shall settle or compromise, or consent to the entry of any judgment in, any pending or threatened Indemnified Proceeding (A) in respect of which any payment would result hereunder or under any other Operative Document, (B) which includes an injunction that will adversely affect any Indemnifying Party, (C) which involves an admission of fact adverse to the Indemnifying Party or a finding or admission of any violation of law or the rights of any Person by the Indemnifying Party, or (D) which is in the nature of a criminal or regulatory action, without the prior written consent of the Indemnifying Party, such consent not to be unreasonably conditioned, withheld or delayed.

Section 11. No Petition. Each of the Company and Holdings covenants and agrees that, prior to the date which is one year and one day after the expiration of the Purchase Option Period, it will not institute or join in the institution of any bankruptcy, insolvency, reorganization or similar proceeding against the Symphony Collaboration. The provisions of this Section 11 shall survive the termination of this Agreement.

Section 12. Third-Party Beneficiary. Each of the Parties agrees that each Symphony Fund shall be a third-party beneficiary of this Agreement.

Section 13. Notices. Any notice, request, demand, waiver, consent, approval or other communication which is required or permitted to be given to any Party shall be in writing addressed to the Party at its address set forth below and shall be deemed given (i) when delivered to the Party personally, (ii) if sent to the Party by facsimile transmission (promptly followed by a hard-copy delivered in accordance with this Section 13), when the transmitting Party obtains written proof of transmission and receipt; provided, however, that notwithstanding the foregoing, any communication sent by facsimile transmission after 5:00 PM (receiving Party’s time) or not on a Business Day shall not be deemed received until the next Business Day, (iii) when delivered by next Business Day delivery by a nationally recognized courier service, or (iv) if sent by registered or certified mail, when received, provided postage and registration or certification fees are prepaid and delivery is confirmed by a return receipt:

(b) Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court and Delaware State court or federal court of the United States of America sitting in The City of New York, Borough of Manhattan or Wilmington, Delaware, and any appellate court from any jurisdiction thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the Parties hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court, any such Delaware State court or, to the fullest extent permitted by law, in such federal court. Each of the Parties agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any Party may otherwise have to bring any action or proceeding relating to this Agreement.

(c) Each of the Parties irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New York State or federal court, or any Delaware State or federal court. Each of the Parties hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action

or proceeding in any such court. Each of the parties hereby consents to service of process by mail.

Section 15. Waiver of Jury Trial. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 16. Entire Agreement. This Agreement (including any Annexes, Schedules, Exhibits or other attachments hereto) constitutes the entire agreement between the Parties with respect to the matters covered hereby and supersedes all prior and contemporaneous agreements, correspondence, discussion, and understanding with respect to such matters between the Parties, excluding the Operative Documents.

Section 17. Amendment; Successors; Counterparts.

(a) The terms of this Agreement shall not be altered, modified, amended, waived or supplemented in any manner whatsoever except by a written instrument signed by each of the Parties.

(b) Except as set forth in Section 12, nothing expressed or implied herein is intended or shall be construed to confer upon or to give to any Person, other than the Parties, any right, remedy or claim under or by reason of this Agreement or of any term, covenant or condition hereof, and all the terms, covenants, conditions, promises and agreements contained herein shall be for the sole and exclusive benefit of the Parties and their successors and permitted assigns.

(c) This Agreement may be executed in one or more counterparts, each of which, when executed, shall be deemed an original but all of which, taken together, shall constitute one and the same Agreement.

Section 18. Specific Performance. The Parties acknowledge that irreparable damage would result if this Agreement were not specifically enforced, and they therefore agree that the rights and obligations of the Parties under this Agreement may be enforced by a decree of specific performance issued by a court of competent jurisdiction.

The Parties further acknowledge and agree that a decree of specific performance may not be an available remedy in all circumstances.

Section 19. Severability.

(b) No Party shall take any tax position inconsistent with any position described in Section 20(a) above, except (i) in the event of a “determination” (as defined in Section 1313 of the Code) to the contrary, or (ii) in the event either of the Parties receives an opinion of counsel to the effect that there is no reasonable basis in law for such a position or that a tax return cannot be prepared based on such a position without being subject to substantial understatement penalties; provided, however, that in the case of the Company, such counsel shall be reasonably satisfactory to Holdings.

Interest as aforesaid shall be charged for the actual number of days elapsed over a year consisting of three hundred sixty (360) days on the actual daily outstanding balance hereof; provided; that interest calculations shall include the date of funding of the Convertible Term Loan, but shall exclude the Maturity Date.

reduced by the Converted Amount (as defined below), and such Reduction shall be notified to Holdings in writing.

Section 23. Upon and after the occurrence of an Event of Default (as defined below), the Convertible Term Loan may be declared, and immediately shall become, due and payable in cash without demand, notice or legal process of any kind. An “Event of Default” shall occur if:

(a) at any time following the tenth (10th) consecutive Business Day that the number of authorized and outstanding shares of the Company’s common stock, par value $0.01 per share (the “Company Common Stock”) is less than the number of shares of Company Common Stock that Holdings would be entitled to receive upon a conversion of the full Conversion Amount of this Convertible Note;

(e) Reclassification; Exchange; Combinations or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon exercise of the Conversion Right (other than stock splits and reverse stock splits), the principal amount payable hereunder (together with any unpaid interest thereon) shall be paid in full in cash on the effective date of such reclassification, exchange, substitution or other event (but in no event after the Maturity Date).

(f) Representations and Warranties Regarding Conversion. The Company hereby restates the representations and warranties set forth in Section 4.02 of the Stock and Warrant Purchase Agreement, dated as of October 1, 2008, between Holdings and the Company (the “Stock and Warrant Purchase Agreement”), respectively, as of the date hereof.

(g) Reservation of Shares. The Company shall reserve sufficient shares of Company Common Stock out of its authorized shares to ensure that Shares will be immediately available upon exercise of the Conversion Right.

(h) Miscellaneous.

(i) Term. The Conversion Right is exercisable in whole or in part on the Maturity Date. If the Conversion Right is exercised in part on the Maturity Date, the balance of the principal and interest due pursuant to this Convertible Note shall be due and payable in cash on the Maturity Date.

Section 29.

Section 30. Whenever in this Convertible Note reference is made to Holdings or the Company, such reference shall be deemed to include, as applicable, a reference to their respective successors and assigns. The provisions of this Convertible Note shall be binding upon the Company and its successors and assigns, and shall inure to the benefit of Holdings and its successors and assigns.
