AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of February 16, 2011 (this “Agreement”), among Sanofi-Aventis, a French société anonyme (“Parent”), GC Merger Corp., a Massachusetts corporation and wholly-owned Subsidiary of Parent (“Purchaser”), and Genzyme Corporation, a Massachusetts corporation (the “Company”).

WHEREAS, Purchaser has previously commenced a cash tender offer (the “Pending Offer”) to purchase all of the issued and outstanding shares of common stock, par value $0.01 per share, of the Company (each, a “Share” and, collectively, “Shares”), subject to certain terms and conditions;

WHEREAS, the Boards of Directors of Parent, Purchaser and the Company have approved the acquisition of the Company on the terms and subject to the conditions set forth in this Agreement and, accordingly, Purchaser has agreed to amend the Pending Offer to provide for the purchase of all of the issued and outstanding Shares (as the Pending Offer is so amended and as it may be amended from time to time as permitted by this Agreement, the “Offer”), for (a) $74.00 per Share (the “Cash Consideration”), net to the seller in cash without interest thereon and subject to Section 3.6 hereof, and (b) one contingent value right (“CVR”) per Share, issued by Parent subject to and in accordance with a Contingent Value Rights Agreement, by and among Parent and a trustee mutually agreeable to Parent and the Company (the “Trustee”), in substantially the form attached hereto as Exhibit A (the “CVR Agreement”), and subject to the conditions set forth herein (such Cash Consideration plus CVR, or any higher consideration per Share as may be paid in the Offer pursuant to the terms of this Agreement, the “Offer Price”);

WHEREAS, following consummation of the Offer, Purchaser will merge with and into the Company (the “Merger”) and each Share that is issued and outstanding immediately prior to the Effective Time (other than Shares held in the treasury of the Company or owned by Parent or any direct or indirect wholly-owned Subsidiary of Parent or the Company immediately prior to the Effective Time for which no consideration will be paid) will be canceled and converted into the right to receive consideration equal to the Offer Price, upon the terms and conditions set forth herein;

WHEREAS, the Board of Directors of the Company (the “Company Board”) has, (i) adopted this Agreement, (ii) approved the Offer and the Merger and (iii) determined to recommend that the holders of Shares accept the Offer and tender their Shares to Purchaser; and

WHEREAS, the Board of Directors of Purchaser has, on the terms and subject to the conditions set forth herein, adopted this Agreement, and Parent, in its capacity as the sole shareholder of Purchaser, has approved this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Parent, Purchaser and the Company hereby agree as follows:

ARTICLE I
THE OFFER

Section 1.1 The Offer.

(a) (i) Parent shall cause Purchaser to, and Purchaser shall, amend the Pending Offer to reflect the execution of this Agreement and the terms hereof as promptly as reasonably practicable after the date of this Agreement (but in no event later than the fifteenth (15th) Business Day following the date of this Agreement). The date on which Purchaser amends the Pending Offer is referred to in this Agreement as the “Offer Amendment Date.” The obligations of Purchaser (and of Parent to cause Purchaser) to accept for payment and to pay for any Shares tendered pursuant to the Offer will be subject only to the satisfaction or waiver of those conditions set forth in Annex I (the “Offer Conditions”). Unless extended in accordance with Section 1.1(a)(ii), the Offer shall expire on the later of (A) one (1) Business Day after the Registration Statement is declared effective or (B) twenty (20) Business Days after the Offer Amendment Date (the “Initial Expiration Date”), or, if the Offer has been extended in accordance with Section 1.1(a)(ii), at the time and date to which the Offer has been so extended (the Initial Expiration Date, or such later time and date to which the Offer has been extended in accordance with Section 1.1(a)(ii), the “Expiration Date”). Purchaser expressly reserves the right (but will not be obligated) at any time or from time to time in its sole discretion to waive any Offer Condition or modify or amend the terms of the Offer, except that, without the prior written consent of the Company, Purchaser will not (A) decrease the Cash Consideration, amend the terms of the CVR or CVR Agreement, or change the form of the consideration payable in the Offer, (B) decrease the number of Shares sought pursuant to the Offer, (C) amend or waive the Minimum Tender Condition or the CVR Condition (as defined in Annex I), (D) add to the conditions set forth on Annex I, (E) modify the conditions set forth on Annex I in a manner adverse to the holders of Shares, (F) extend the Expiration Date of the Offer except as required or permitted by Section 1.1(a)(ii), (G) make any other change in the terms or conditions of the Offer that is adverse to the holders of Shares or (H) increase the Cash Consideration by an increment of less than $0.25.

(ii) Subject to the terms and conditions of this Agreement and to the satisfaction or waiver (to the extent permitted hereunder) by Purchaser of the Offer Conditions as of any scheduled Expiration Date, Purchaser will, and Parent will cause Purchaser to, accept for payment and pay for Shares validly tendered and not withdrawn pursuant to the Offer promptly after such scheduled Expiration Date (the date and time of acceptance for payment, the “Acceptance Time”), and Purchaser will, and Parent will cause Purchaser to, immediately accept and promptly pay for all Shares as they are validly tendered during any subsequent offering period for the Offer in accordance with Rule 14d-11 (a “Subsequent Offering Period”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Purchaser (A) will extend the Offer for one or more periods of time of up to ten (10) Business Days per extension if at any scheduled Expiration Date any of the Offer Conditions is not satisfied; or (B) will extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the “SEC”) or the staff thereof or The NASDAQ Stock Market LLC (“Nasdaq”) applicable to the Offer; provided, that in no circumstance will Purchaser be required to extend the Offer beyond the Outside Date.

(b) On the Offer Amendment Date, Parent and Purchaser will file or cause to be filed with the SEC an amendment to Parent and Purchaser’s Tender Offer Statement on Schedule TO (collectively with all amendments and supplements thereto, the “Schedule TO”) with respect to the Offer that will contain the offer to purchase and related letter of transmittal and summary advertisement and other ancillary Offer documents and instruments pursuant to which the Offer will be made (collectively with any supplements or amendments thereto, the “Offer Documents”). The Company will be given a reasonable opportunity to review and comment on the Offer Documents prior to their filing with the SEC. Parent and Purchaser agree to (i) promptly provide the Company and its counsel with a copy of any written comments (or a description of any oral comments) received by Parent, Purchaser or their counsel from the SEC or its staff with respect to the Offer Documents, (ii) consult with the Company regarding any such comments prior to responding thereto and (iii) provide the Company with copies of any written comments or responses thereto. Parent and Purchaser agree to take all steps necessary to cause the Offer Documents to be disseminated to holders of Shares to the extent required by applicable federal securities Laws. Each of Parent, Purchaser and the Company agrees to promptly correct any information provided by it for use in the Offer Documents if and to the extent that it has become false or misleading in any material respect. Parent and Purchaser further agree to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities Laws.

(c) Parent will provide or cause to be provided to Purchaser on a timely basis the funds necessary to purchase any Shares that Purchaser becomes obligated to purchase pursuant to the Offer.

(d) Purchaser will not terminate the Offer prior to any scheduled Expiration Date without the prior written consent of the Company, except if this Agreement is terminated pursuant to ARTICLE VIII. If this Agreement is terminated pursuant to ARTICLE VIII, Purchaser will, and Parent will cause Purchaser to, promptly (and in any event within twenty-four (24) hours of such termination) terminate the Offer and shall not acquire any Shares pursuant thereto. If the Offer is terminated by Purchaser, or this Agreement is terminated pursuant to ARTICLE VIII prior to the acquisition of Shares in the Offer, Purchaser shall promptly return, and will cause any depositary acting on behalf of Purchaser to return, in accordance with applicable Law, all tendered Shares to the registered holders thereof.

(e) The (i) Offer Price and (ii) Merger Consideration shall be adjusted appropriately to reflect any reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange or readjustment of shares, or any stock dividend or stock distribution occurring (or for which a record date is established) after the date hereof and prior to (A) the payment by Purchaser for Shares validly tendered and not properly withdrawn in connection with the Offer (with respect to the Offer Price) or (B) the Effective Time (with respect to the Merger Consideration).

(f) No Fractional CVRs. No fraction of a CVR will be issued in connection with the Offer, the Merger or other transaction contemplated by this Agreement, and no certificates or scrip for any such fractional CVR shall be issued. Each holder of Shares and/or other security of the Company who would otherwise be entitled to receive a fraction of a CVR

pursuant to this Agreement, after aggregating all fractional CVRs to be received by such holder (a “Fractional CVR”), shall, upon surrender of such holder’s Shares and/or other securities of the Company, receive one CVR in exchange for such Fractional CVR if the amount of such Fractional CVR is greater than or equal to 0.50 or no consideration for such Fractional CVR if the amount of such Fractional CVR is less than 0.50.

Section 1.2 Company Consent; Schedule 14D-9. Contemporaneously with the filing of the amendment to Schedule TO or as promptly as practicable thereafter, the Company will file with the SEC an amendment to its Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments and supplements thereto, including amendments pursuant to this Section 1.2, the “Schedule 14D-9”) containing, subject to Section 6.3(d) and Section 6.3(e), the Company Board Recommendation. The Company hereby consents to the inclusion of the Company Board Recommendation in the Offer Documents and to the inclusion of a copy of the Schedule 14D-9 with the Offer Documents mailed or furnished to the holders of Shares. Except with respect to any amendments filed in connection with an Acquisition Proposal or a Change of Board Recommendation, Parent and Purchaser will be given a reasonable opportunity to review and comment on the Schedule 14D-9 prior to its filing with the SEC. The Company agrees to (i) promptly provide Parent, Purchaser and their counsel with a copy of any written comments (or a description of any oral comments) received by the Company or their counsel from the SEC or its staff with respect to the Schedule 14D-9, (ii) consult with Parent and Purchaser regarding any such comments prior to responding thereto and (iii) provide Parent and Purchaser with copies of any written comments or responses thereto. The Company, Parent and Purchaser agree to promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that it has become false or misleading in any material respect. The Company further agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities Laws.

Section 1.3 Shareholder Lists. In connection with the Offer, the Company will cause its transfer agent to, furnish Parent and Purchaser with mailing labels, security position listings and readily available computer files containing the names and addresses of the record holders of the Shares as of recent date and will furnish or cause to be furnished to Parent and Purchaser such information and assistance (including periodic updates of such information) as Parent or Purchaser or their agents may reasonably request in communicating the Offer to the record and beneficial holders of the Shares. Subject to the requirements of applicable Law, and except for such actions as are reasonably necessary to disseminate the Offer Documents, each of Parent and Purchaser will hold all information and documents provided to it under this Section 1.3 in confidence in accordance with the letter agreement regarding confidentiality, by and between Parent and the Company, dated January 31, 2011 (the “Confidentiality Agreement”), and will use such information and documents only in connection with the Offer, and, if this Agreement has been terminated by Parent or Purchaser, will deliver to the Company all such information and documents (and all copies thereof).

Section 1.4 Directors.

(a) Promptly upon the purchase by Purchaser pursuant to the Offer of such number of Shares as satisfy at least the Minimum Tender Condition, and from time to time

thereafter, Purchaser will be entitled to designate such number of directors, rounded up to the next whole number, on the Company Board as will give Purchaser representation on the Company Board equal to the product of (i) the total number of directors on the Company Board (after giving effect to any increase in the number of directors pursuant to this Section 1.4) and (ii) the percentage that such number of Shares so purchased bears to the total number of then-outstanding Shares on a fully-diluted basis, and the Company will, upon request by Purchaser, promptly increase the size of the Company Board or use commercially reasonable efforts to seek the resignations of such number of directors as is necessary to provide Purchaser with such level of representation and will use commercially reasonable efforts to cause Purchaser’s designees to be so elected or appointed. Subject to the applicable requirements of Nasdaq, the Company will also use commercially reasonable efforts to cause individuals designated by Purchaser to constitute the same percentage of each committee of the Company Board as the percentage of the entire Company Board represented by individuals designated by Purchaser. The Company’s obligations to appoint designees to the Company Board will be subject to Section 14(f) of the Exchange Act. At the request of Purchaser, the Company will file with the SEC and mail to the holders of Shares the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. Parent and Purchaser will supply to the Company all information with respect to themselves and their respective officers, directors and Affiliates required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and Parent and Purchaser will be solely responsible for such information. For purposes of this Agreement, such information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder that is filed with the SEC and mailed to holders of Shares will be considered part of the Schedule 14D-9.

(b) Notwithstanding the provisions of this Section 1.4, the Company, Parent and Purchaser shall cause the Company Board to include, at all times prior to the Effective Time, at least three of the members of the Company Board, selected by the members of the Company Board, who were directors of the Company on the date of this Agreement (“Continuing Directors”), each of whom shall be an “independent director” as defined by Rule 4200(a)(15) of the Nasdaq Marketplace Rules and eligible to serve on the Company’s audit committee under the Exchange Act and the applicable requirements of Nasdaq; provided, however, that if at any time prior to the Effective Time there shall be fewer than three (3) Continuing Directors serving as directors of the Company for any reason, then the Company Board shall take all necessary action (including creating a committee of the Company Board) to cause an individual selected by the remaining Continuing Directors (or Continuing Director, if there shall be only one (1) Continuing Director remaining) who satisfies the foregoing independence requirements and who is not an officer, director, stockholder or designee of Parent or any of its Affiliates to be appointed to serve on the Company Board (and such individual shall be deemed to be a Continuing Director for all purposes under this Agreement).

(c) Following the election or appointment of Purchaser’s designees pursuant to Section 1.4(a) and prior to the Effective Time, any action by the Company with respect to any amendment, supplement, modification, or waiver of any term of this Agreement, any termination of this Agreement by the Company, any extension of time for the performance of any of the obligations or other acts of Parent or Purchaser under this Agreement, any waiver of compliance with any of the agreements or conditions under this Agreement that are for the benefit of the Company, any amendment to the Articles of Organization or Bylaws, any authorization of an

agreement between the Company and any of its Affiliates, on the one hand, and Parent, Purchaser or any of their Affiliates, on the other hand, any exercise of the Company’s rights or remedies under this Agreement and any action to seek to enforce any obligation of Parent or Purchaser under this Agreement (or any other action by the Company Board with respect to this Agreement, the Offer or the Merger if such other action adversely affects, or could reasonably be expected to adversely affect, any of the holders of Shares other than Parent or Purchaser) may only be authorized by, and will require the authorization of, a majority of the Continuing Directors (or by the Continuing Director should there be only one). For purposes of considering any matter set forth in this Section 1.4(c), the Continuing Directors will be permitted to meet without the presence of the other directors. The Continuing Directors will have the authority to retain such counsel (which may include current counsel to the Company) and other advisors at the expense of the Company as determined by the Continuing Directors and will have the authority to institute any action on behalf of the Company to enforce performance of this Agreement or any of the Company’s rights hereunder. The Company will indemnify and advance expenses to, and Parent will cause the Company to indemnify and advance expenses to, the Continuing Directors in connection with their service as directors of the Company prior to the Effective Time to the fullest extent permitted by applicable Law and in accordance with the provisions of Section 6.5 hereof.

(d) In the event that Purchaser’s designees are elected or appointed to the Company Board pursuant to Section 1.4(a), until the Effective Time, (i) the Company Board will have at least such number of directors as may be required by the Nasdaq rules or the federal securities Laws who are considered independent directors within the meaning of such rules and Laws (“Independent Directors”) and (ii) each committee of the Company Board that is required (or a majority of which is required) by the Nasdaq rules or the federal securities Laws to be composed solely of Independent Directors will be so composed; provided, however, if the number of Independent Directors is reduced below the number of directors as may be required by such rules or Laws for any reason, the remaining Independent Director(s) will be entitled to designate persons to fill such vacancies who will be deemed to be Independent Directors for purposes of this Agreement or, if no Independent Director then remains, the other directors will designate such number of directors as may be required by the Nasdaq rules and the federal securities Laws to fill such vacancies who will not be shareholders or Affiliates of Parent or Purchaser, and such Persons will be deemed to be Independent Directors for purposes of this Agreement.

Section 1.5 Top-Up Option.

(a) Subject to the terms and conditions set forth herein, the Company hereby grants to Purchaser an irrevocable option (the “Top-Up Option”) to purchase, at a price per share equal to the greater of (i) the closing price of a Share on Nasdaq the last trading day prior to the exercise of the Top-Up Option or (ii) the Cash Consideration, that number of newly issued Shares (the “Top-Up Shares”) equal to the lowest number of Shares that, when added to the number of Shares owned by Purchaser at the time of exercise of the Top-Up Option (after giving effect to the issuance of the Top-Up Shares but excluding from Purchaser’s ownership, but not from the outstanding Shares, Shares tendered pursuant to guaranteed delivery procedures that have not yet been delivered in settlement or satisfaction of such guarantee), constitutes one Share more than ninety percent (90%) of all outstanding Shares (assuming the issuance of the Top-Up

Shares). The Top-Up Option will only be exercised one time by Purchaser in whole but not in part, and only if clauses (x) and (y) of the following sentence are satisfied. The Top-Up Option will be exercised by Purchaser, and Parent will cause Purchaser to exercise the Top-Up Option, promptly (but in no event later than one (1) Business Day) after the Acceptance Time or the expiration of a Subsequent Offering Period, as applicable, if (x) at the Acceptance Time or the expiration of such Subsequent Offering Period, as applicable, Purchaser owns in the aggregate at least seventy-five percent (75%) of all Shares then outstanding (excluding from Purchaser’s ownership, but not from the outstanding Shares, Shares tendered pursuant to guaranteed delivery procedures that have not yet been delivered in settlement or satisfaction of such guarantee) and (y) after giving effect to the exercise of the Top-Up Option, Purchaser would own in the aggregate one Share more than ninety percent (90%) of the number of outstanding Shares (after giving effect to the issuance of the Top-Up Shares but excluding Shares tendered pursuant to guaranteed delivery procedures that have not yet been delivered in settlement or satisfaction of such guarantee); provided, however, that the obligation of Purchaser to exercise the Top-Up Option and the obligation of the Company to deliver Top-Up Shares upon the exercise of the Top-Up Option is subject to the conditions that (A) no provision of any applicable Law and no applicable order, injunction or other judgment shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Shares in respect of such exercise, (B) Purchaser irrevocably commits upon acquisition of the Top-Up Shares to effect the Merger pursuant to Section 2.7, and (C) the number of Top-Up Shares to be issued pursuant to the Top-Up Option does not exceed the number of authorized and unissued shares of Company Common Stock less the maximum number of shares of Company Common Stock potentially necessary for issuance with respect to outstanding Company Equity Awards or other obligations of the Company. The parties will cooperate to ensure that the issuance of the Top-Up Shares is accomplished consistent with all applicable Laws, including compliance with an applicable exemption from registration under the Securities Act. The Top-Up Option shall terminate concurrently with the termination of this Agreement. Purchaser may assign the Top-Up Option and its rights and obligations pursuant to this Section 1.5, in its sole discretion, to Parent.

(b) Upon the exercise of the Top-Up Option in accordance with Section 1.5(a), Parent will so notify the Company and will set forth in such notice (i) the number of Shares that are expected to be owned by Purchaser immediately preceding the purchase of the Top-Up Shares and (ii) a place and time for the closing of the purchase of the Top-Up Shares (which, subject to applicable Law and any required regulatory approvals, will be effected as promptly as practicable and not more than two (2) Business Days after the date such notice is delivered to the Company). Such notice will also include an undertaking signed by Parent and Purchaser that, as promptly as practicable following such exercise of the Top-Up Option, Purchaser will, and Parent will cause Purchaser to, as promptly as practicable after such exercise and the delivery by the Company of the Top-Up Shares, consummate the Merger in accordance with Section 2.7. Prior to the closing of the purchase of the Top-Up Shares, upon Purchaser’s request, the Company shall cause its transfer agent to certify in writing to Purchaser the number of Shares issued and outstanding as of immediately prior to the exercise of the Top-Up Option and after giving effect to the issuance of the Top-Up Shares. At the closing of the purchase of the Top-Up Shares, Purchaser will pay the Company the aggregate price required to be paid for the Top-Up Shares, and the Company shall cause to be issued to Purchaser the Top-Up Shares.

(c) The aggregate purchase price payable for the Top-Up Shares will be paid by Purchaser as follows: (i) the portion of the aggregate purchase price equal to the par value of the Top-Up Shares shall be paid in cash and (ii) the balance of the remaining aggregate purchase price may be paid, at Purchaser’s option, (A) in cash or (B) by executing and delivering to the Company a promissory note having a principal amount equal to the balance of the remaining aggregate purchase price, or some combination thereof. The Company Board has determined that such consideration for the Top-Up Shares is adequate. Any such promissory note will be in the form attached hereto as Annex II, and will include the following terms: (1) the maturity date will be one (1) year after issuance, (2) the unpaid principal amount of the promissory note will accrue simple interest at a per annum rate of 1.31% and (3) the promissory note may be prepaid in whole or in part at any time, without penalty or prior notice.

(d) The parties shall cooperate to ensure that the issuance of the Top-Up Shares is accomplished consistent with all applicable Law. Parent and Purchaser acknowledge that the Top-Up Shares will not be registered under the Securities Act and would be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Each of Parent and Purchaser hereby represents and warrants to the Company that Purchaser will be, upon the purchase of the Top-Up Shares, an “accredited investor,” as defined in Rule 501 of Regulation D under the Securities Act. Purchaser agrees that the Top-Up Option is being, and the Top-Up Shares would be, acquired by Purchaser for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof (within the meaning of the Securities Act).

Section 1.6 CVRs.

(a) Parent will, at or prior to the Acceptance Time, cause the CVR Agreement to be duly authorized, executed and delivered by Parent and the Trustee.

(b) Within fifteen (15) Business Days after the date of this Agreement, Parent and Purchaser will prepare and file a registration statement on Form F-4 with the SEC to register the CVRs to be issued in connection with the Offer and the Merger (such registration statement, together with any amendments, supplements and exhibits thereto, the “Registration Statement”). The Registration Statement will include a preliminary prospectus containing the information required under Rule 14d-4(b) under the Exchange Act (the “Preliminary Prospectus”). The Company will be given a reasonable opportunity to review and comment on the Registration Statement prior to filing with the SEC. Parent and Purchaser will use their reasonable best efforts to cause the Registration Statement to be declared effective by the SEC and, if required by Law, to have the CVR Agreement become qualified under the Trust Indenture Act, in each case as soon as reasonably practicable after the date of this Agreement. Following the time that the Registration Statement is declared effective, Parent shall file the final prospectus included therein under Rule 424(b) under the Securities Act. In furtherance and not in limitation of the foregoing, Parent and the Purchaser (i) will respond promptly to any comments from the SEC or its staff with respect to the Registration Statement, including, if necessary, by filing amendments to the Registration Statement and (ii) will request that the SEC declare the Registration Statement effective within two (2) Business Days of being informed by the SEC or its staff that either the Registration Statement will not be reviewed or that review of the Registration Statement is complete. Parent and Purchaser agree to (A) promptly provide the Company and its

counsel with a copy of any written comments (or a description of any oral comments) received by Parent, Purchaser or their counsel from the SEC or its staff with respect to the Registration Statement, (B) consult with the Company regarding any such comments prior to responding thereto and (C) provide the Company with copies of any written comments or responses thereto. Parent and Purchaser agree to take all steps necessary to cause the Preliminary Prospectus to be disseminated to holders of Shares as an Offer Document to the extent required by applicable federal securities Laws. Each of Parent, Purchaser and the Company agrees to promptly correct any information provided by it for use in the Registration Statement if and to the extent that it has become false or misleading in any material respect. Parent and Purchaser further agree to take all steps necessary to cause the Registration Statement as so corrected to be filed with the SEC and to cause any revised prospectus therein to be disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities Laws. Parent and Purchaser will use their reasonable best efforts to keep the Registration Statement effective as long as is necessary to consummate the Offer, the Merger and the transactions contemplated by this Agreement. Parent and Purchaser will advise the Company, promptly after they receive notice, of the time when the Registration Statement has become effective, of the issuance of any stop order with respect to the Registration Statement or the suspension of any qualification of the CVRs.

(c) Within fifteen (15) Business Days after the date of this Agreement, Parent will prepare and submit to Nasdaq (or such other exchange(s), electronic trading networks or other suitable trading platforms as are mutually agreed by Parent and the Company) an application covering the CVRs being issued in the Offer and the Merger and will use reasonable best efforts to cause the CVRs to be approved for listing (subject to notice of issuance) for trading on Nasdaq (or such other exchange(s), electronic trading networks or other suitable trading platforms as are mutually agreed by Parent and the Company) at or prior to the Acceptance Time.

Section 3.2 Treatment of Equity Awards.

(a) As soon as reasonably practicable following the date of this Agreement, and in any event prior to the Acceptance Time, the Company Board (or, if appropriate, any committee administering any Company equity incentive plan (a “Company Equity Plan”)) will adopt resolutions, and the Company will take all other actions as may be required in accordance with applicable Law, each Company Equity Plan and the Company Equity Awards to give effect to the transactions contemplated by this Agreement (including this Section 3.2(a)) and to provide that:

(ii) each unexercised Company Stock Option that is outstanding immediately prior to the Acceptance Time, whether or not vested or subject to any performance or other condition, that has an Option Exercise Price that is less than the Cash Consideration, will be cancelled, and, in exchange therefor, each former holder of each such cancelled Company Stock Option will be entitled to receive, in consideration of the cancellation of such Company Stock Option and in settlement therefor, (A) an amount in cash equal to (x) the excess, if any, of (i) the Cash Consideration over (ii) the Option Exercise Price, multiplied by (y) the total number

of Shares subject to such Company Stock Option at the time of cancellation, and (B) one CVR per Share subject to such Company Stock Option at the time of cancellation;

(iii) each unexercised Company Stock Option that is outstanding immediately prior to the Acceptance Time, whether or not vested or subject to any performance or other condition, that has an Option Exercise Price that is equal to or greater than the Cash Consideration, will be cancelled at the Acceptance Time without consideration;

(iv) each Share which is a restricted Share (“Company Restricted Stock”) that is outstanding immediately prior to the Acceptance Time will vest in full, if unvested, and become non-forfeitable effective immediately prior to the Acceptance Time and will be cancelled at the Acceptance Time and converted into the right to receive the Merger Consideration, and

(c) The Company’s 2009 Employee Stock Purchase Plan (“ESPP”) will continue to be operated in accordance with its terms and past practice for each current Offering (as defined in the ESPP) (each, a “Current Offering”, and collectively, the “Current Offerings”); provided that if the Acceptance Time is expected to occur prior to the end of any of the Current Offerings, the Company will take all action as may be necessary to provide for Shares to be purchased in the applicable Current Offering on an earlier date in accordance with Section 5 of the ESPP (such date, the “Early ESPP Purchase Date”). The Early ESPP Purchase Date shall be prior to the Acceptance Time, and the Company will notify each ESPP participant in writing, prior to such Early ESPP Purchase Date, that the date during the applicable Current Offering on which his or her purchase right may be exercised has been changed to the Early ESPP Purchase Date (including for purposes of determining the per share exercise price of such purchase right pursuant to Section 4 of the ESPP) and that his or her purchase right will be exercised automatically on the Early ESPP Purchase Date, unless prior to such date, he or she has canceled his or her election to participate in the applicable Current Offering as provided in Section 10 of the ESPP. The Company will suspend the commencement of any future Offerings under the ESPP (excepting, for the avoidance of doubt, the Current Offerings) unless and until this Agreement is terminated.

(d) Without limiting the foregoing, the Company shall take all actions as may be necessary to terminate each Company Equity Plan and the ESPP as of the Acceptance Time.

Section 3.3 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, other than as provided in Section 3.3(b), any Shares that are issued and outstanding immediately prior to the Effective Time and held by a Company shareholder who has not voted in favor of the Merger or consented thereto in writing and who has demanded properly in writing payment of fair value for such Shares in accordance with Part 13 of the MBCA (the “Dissenting Shares”) will not be converted into the right to receive the Merger Consideration unless and until such Company shareholder will have effectively withdrawn or lost (through failure to perfect or otherwise) such shareholder’s right to obtain payment of the fair value of such shareholder’s Dissenting Shares under the MBCA but will instead be entitled only to such rights with respect to such Dissenting Shares as may be granted to such shareholder under Part 13 of the MBCA. From and after the Effective Time, Dissenting Shares will not be entitled to vote for any purpose or be entitled to the payment of dividends or other distributions (except dividends or other distributions payable to shareholders of record prior to the Effective Time). Parent, Purchaser and the Company agree that the Surviving Corporation will not assert that any Top-Up Shares or any promissory note used as a portion of the consideration for the Top-Up Shares negatively impact the fair value of any Dissenting Shares. The parties hereby agree and acknowledge that in any appraisal proceeding with respect to the Dissenting Shares, and to the fullest extent permitted by applicable Law, the fair value of the Dissenting Shares will be determined in accordance with Part 13 of the MBCA without regard to the Top-Up Option, the Top-Up Shares or any promissory note delivered by Purchaser or Parent to the Company in payment for the Top-Up Shares.

(b) The Company will give Parent (i) reasonably prompt notice of any demands for payment of fair value received by the Company, and any withdrawals thereof, received from shareholders or provided to shareholders by the Company with respect to any Dissenting Shares or Shares claimed to be Dissenting Shares, and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for such payment under the MBCA. The Company will not, except with the prior written consent of Parent or as otherwise required by applicable Law, make any payment with respect to any such purported payment demands or offer to settle or settle any such payment demands.

(c) If any Company shareholder who holds Dissenting Shares effectively withdraws or loses (through failure to perfect or otherwise) such shareholder’s right to obtain payment of the fair value of such shareholder’s Dissenting Shares under the MBCA, then, as of the later of the Effective Time and the occurrence of such effective withdrawal or loss, such shareholder’s Shares will no longer be Dissenting Shares and, if the occurrence of such effective withdrawal or loss is later than the Effective Time, will be treated as if the shareholder had, as of the Effective Time, been converted into the right to receive the Merger Consideration, without interest, as set forth in Section 3.1(a).

Section 3.4 Surrender of Shares.

(a) Prior to the Acceptance Time and from time to time after the Acceptance Time, Parent will deposit (or cause to be deposited) with a bank or trust company designated by Parent and reasonably acceptable to the Company (the “Paying Agent”) (i) cash in an amount sufficient to pay the aggregate Cash Consideration and (ii) certificates representing the aggregate number of CVRs issuable pursuant to this Agreement and the CVR Agreement, and will cause the Paying Agent to timely make, all payments contemplated in Section 3.4(b). Such cash may be invested by the Paying Agent as directed by Parent; provided, that such investments will be in short-term obligations of the United States of America with maturities of no more than thirty (30) days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America or in commercial paper obligations rated A-1 or P-1 or better by ▇▇▇▇▇’▇ Investors Service, Inc. or Standard & Poor’s Corporation, respectively. Any interest or income produced by such investments will be payable to the Surviving Corporation or Parent, as Parent directs.

(b) Exchange Procedures. Promptly after the Effective Time (and in any event within two (2) Business Days thereafter), the Paying Agent will mail to each holder of record of a certificate (a “Certificate”) or a book-entry share (a “Book-Entry Share”), which immediately prior to the Effective Time represented outstanding Shares, whose shares were converted pursuant to Section 3.1 into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery will be effected, and risk of loss and title to the Certificate or Book-Entry Shares will pass, only upon delivery of the Certificates or Book-Entry Shares to the Paying Agent and will be in such form and have such other provisions acceptable to the Company and Parent); and (ii) instructions for effecting the surrender of the Certificates or Book-Entry Shares in exchange for payment of the Merger Consideration. Upon surrender of a Certificate or Book-Entry Shares for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed and properly completed, the holder of such Certificate or Book-Entry Share will be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate or Book-Entry Share, and the Certificate or Book-Entry Share so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section 3.4(b), each Certificate or Book-Entry Share will be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration and will not evidence any interest in, or any right to exercise the rights of a shareholder or other equity holder of, the Company or the Surviving Corporation.

(c) At any time following the date that is one (1) year after the Effective Time, Parent will be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) or CVR certificates that have been made available to the Paying Agent and that have not been disbursed to holders of Certificates and Book-Entry Shares, and thereafter such holders will be entitled to look to the Surviving Corporation (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration payable upon surrender of their Certificates and Book-Entry Shares. The Surviving Corporation will pay all charges and expenses, including those of the Paying Agent, in connection with the exchange of Shares for the Merger Consideration.

(d) After the Effective Time, the stock transfer books of the Company will be closed, and thereafter there will be no further registration of transfers of Shares that were

outstanding prior to the Effective Time. After the Effective Time, Certificates and Book-Entry Shares presented to the Surviving Corporation for transfer will be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth in, this ARTICLE III.

(e) In the event that any Certificate has been lost, stolen or destroyed, upon the holder’s delivery of an affidavit of loss to the Paying Agent, the Paying Agent will deliver in exchange for the lost, stolen or destroyed Certificate the applicable Merger Consideration payable in respect of the Shares represented by such Certificate.

Section 3.5 Section 16. The Company Board will, to the extent necessary, take appropriate action, prior to or as of the Acceptance Time, to approve, for purposes of Section 16(b) of the Exchange Act the disposition and cancellation of Shares (including derivative securities with respect to Shares) resulting from the transactions contemplated by this Agreement.

Section 3.6 Withholding. Each of Parent, Purchaser and Surviving Corporation will be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from any amounts payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Shares or Company Equity Awards such amounts as are required to be deducted and withheld therefrom under the United States Internal Revenue Code of 1986, as amended (the “Code”) or the Treasury Regulations thereunder or any other Tax Law; it being understood that, no withholding or deduction shall be made under the Laws of France from any amounts payable or otherwise deliverable pursuant to this Agreement except to the extent that any such deduction or withholding shall be required by a change in Law (or official interpretation thereof announced by the French taxing authorities) after the date hereof. To the extent such amounts are so deducted and withheld, such amounts will be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

Section 3.7 Transfer Taxes. If any payment, including payment in the form of a CVR, pursuant to the Offer or the Merger is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Share, as applicable, is registered, it will be a condition of payment that the Certificate or Book-Entry Share, as applicable, so surrendered will be properly endorsed or will be otherwise in proper form for transfer and that the Person requesting such payment will have paid all transfer and other similar Taxes required by reason of the issuance to a Person other than the registered holder of the Certificate or Book-Entry Share, as applicable, surrendered or will have established to the satisfaction of Parent that such Tax either has been paid or is not applicable. Any other transfer Taxes payable as a result of the consummation of the Offer or the Merger will be paid by Parent, Purchaser or the Surviving Corporation.

ARTICLE IV
REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as set forth in the SEC Reports (without giving effect to any amendment to any such SEC Report filed on or after the date of this Agreement and excluding any disclosures that contain general cautionary, predictive or forward-looking statements set forth in any section of a

SEC Report entitled “risk factors” or constituting “forward-looking statements” or, except to the extent of any factual information contained therein, any other sections of such filings) or in the correspondingly numbered section of the disclosure letter delivered by the Company to Parent and Purchaser concurrently with the execution of this Agreement (the “Company Disclosure Letter”) (provided, however, that a matter disclosed with respect to one representation or warranty will also be deemed to be disclosed with respect to each other representation or warranty to the extent that application to such other representation or warranty is reasonably apparent on the face of such disclosure), the Company hereby represents and warrants to Parent and Purchaser as follows:

Section 4.1 Organization and Qualification. The Company is a corporation validly existing under the Laws of The Commonwealth of Massachusetts and is in good standing with the Secretary of State of Massachusetts, with all corporate power and authority necessary to own its properties and conduct its business as currently conducted and is duly qualified and in good standing as a foreign corporation or entity authorized to do business in each jurisdiction in which the character of the properties owned or held under lease by it or the nature of the business transacted by it makes such qualification necessary, except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. Each Subsidiary of the Company that is a “significant subsidiary” as defined in Rule 1-02(w) of Regulation S-X of the Securities Act is a corporation or other legal entity validly existing and in good standing under the laws of the jurisdiction in which it is incorporated, with all power and authority necessary to own its properties and conduct its business as currently conducted, and is duly qualified and in good standing as a foreign entity authorized to do business in each jurisdiction in which the character of the properties owned or held under lease by it or the nature of the business transacted by it makes such qualification necessary, except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. “Material Adverse Effect” means any state of facts, change, effect, event or occurrence that, individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on the business, condition (financial or otherwise), operations or results of operations of the Company and its Subsidiaries, taken as a whole; provided, however, that any state of facts, changes, effects, events or occurrences will be deemed not to constitute a Material Adverse Effect to the extent resulting from (i) changes generally affecting the economy, financial or securities markets or political, legislative or regulatory conditions or changes in the industries (or therapeutic areas) in which the Company operates; (ii) the announcement or pendency of this Agreement or the transactions contemplated hereby; (iii) any change in the market price or trading volume of the Shares, in and of itself; (iv) acts of war or terrorism (or the escalation of the foregoing) or natural disasters or other force majeure events; (v) changes in any Laws or regulations applicable to the Company or applicable accounting regulations or principles or the interpretation thereof; (vi) the performance of this Agreement and the transactions contemplated hereby, including compliance with covenants set forth herein (excluding the Company operating in the ordinary course of business consistent with past practice), or any action taken or omitted to be taken by the Company at the request or with the prior written consent of Parent or Purchaser; (vii) any legal proceedings commenced by or involving any current or former shareholders of the Company (on their own or on behalf of the Company) arising out of or related to this Agreement or the transactions contemplated hereby; (viii) any failure by the Company to meet any internal or analyst projections or forecasts or estimates of revenues, earnings or other financial metrics for any period, in and of itself; and (ix) the results of any clinical trial involving the humanized

antibody directed against CD52 known as alemtuzumab (the “Alemtuzumab Clinical Trial Results”) except to the extent that such results adversely affect the business of the Company or its Subsidiaries not related to alemtuzumab; provided, however, that state of facts, changes, effects, events or occurrences referred to in clauses (i), (iv) and (v) above shall be considered for purposes of determining whether there has been or would reasonably be expected to be a Material Adverse Effect if and to the extent such state of facts, changes, effects, events or occurrences has had or would reasonably be expected to have a disproportionate adverse effect on the Company and its Subsidiaries, as compared to other companies operating in the industries in which the Company and its Subsidiaries operate. For the avoidance of doubt, (A) “in and of itself” means that the exceptions in clause (iii) and clause (viii) of the definition of “Material Adverse Effect” shall not exclude a determination that a state of facts, change, effect, event or occurrence underlying such change or failure has resulted in a Company Material Adverse Effect and (B) the exception in clause (ix) of the definition of “Material Adverse Effect” shall not exclude a determination that an effect of the Alemtuzumab Clinical Trial Results on the business of the Company or its Subsidiaries that is not related to alemtuzumab has resulted in a Company Material Adverse Effect.

Section 4.2 Articles of Organization and Bylaws. The Company has heretofore made available to Parent true, correct and complete copies of the articles of organization and bylaws of the Company as currently in effect (respectively, the “Articles of Organization” and “Bylaws”). The Company is not in violation of any of the provisions of the Articles of Organization and Bylaws and none of the Company’s Subsidiaries are in violation in any respects of any of the provisions of their organizational or governing documents, in each case, except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

For purposes of this Agreement, the term “Foreign Benefit Plans” shall mean those Company Plans maintained, sponsored or contributed to primarily for the benefit of current or former employees of the Company, any of its Subsidiaries or any of its or their ERISA Affiliates who are or were regularly employed outside the United States. Section 4.13(a) of the Company Disclosure Letter (as the same may be amended or supplemented not later than ten (10) Business Days following the date hereof with respect to Foreign Benefit Plans), sets forth a true, complete and correct list of each material Foreign Benefit Plan (other than any Foreign Benefit Plan required by applicable Law to be so maintained, sponsored or contributed to (or required to be

contributed to) by the Company, any of its Subsidiaries, or any of its or their ERISA Affiliates). For purposes of this Section 4.13, “ERISA Affiliate” shall mean any Person (whether or not incorporated) that, together with any other Person, is or has within the last six (6) years been considered, a single employer under Section 414 of the Code or 4001(b) of ERISA. The Company has no express or implied commitment to terminate, modify or change any Company Plan, other than with respect to a termination, modification or change required by applicable Law, including ERISA or the Code, or as expressly permitted by this Agreement, or which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b) With respect to each Company Plan (other than Foreign Benefit Plans), the Company has made available to Parent (whether through public filings or otherwise) true, complete and correct copies of the following (as applicable): (i) the written document evidencing such Company Plan (or, in any case where Company Plans in substantially the same form cover more than individual, the form of such Company Plan) or, with respect to any such plan that is not in writing, a written description of the material terms thereof; (ii) the summary plan description; (iii) the most recent annual report, financial statement and/or actuarial report; (iv) the most recent determination letter from the Internal Revenue Service (the “IRS”); (v) the most recent Form 5500 required to have been filed with the IRS, including all schedules thereto; (vi) any related trust agreements, insurance contracts or other funding arrangements; (vii) any material notices to or from the IRS or any office or representative of the Department of Labor or other applicable Governmental Entity relating to any unresolved compliance issues in respect of any such Company Plan; and (viii) all material amendments, modifications or supplements to such Company Plan.

(c) Except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, each Company Plan has been administered in accordance with its terms, any applicable Collective Bargaining Agreement, ERISA, the Code (including Section 409A of the Code) and all other applicable Law, including timely filing of all Tax, annual reporting and other governmental filings required by ERISA and the Code and timely contribution (or, if not yet due, proper financial reporting) of any amounts required to be made under the terms of any of the Company Plans as of the date of this Agreement. With respect to each of the Company Plans, no event has occurred and there exists no condition or set of circumstances in connection with which the Company or any of its Subsidiaries would be subject to any liability (contingent or otherwise), that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect. Each Company Plan that is intended to be “qualified” under Section 401 of the Code has received a favorable determination letter from the IRS to such effect and, to the knowledge of the Company, no fact, circumstance or event has occurred or exists since the date of such determination letter that would reasonably be expected to adversely affect the qualified status of any such Company Plan. Except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, none of the Company or any of its Subsidiaries has received notice of, and there are no pending or, to the knowledge of the Company, threatened, audits or investigations by any Governmental Entity with respect to, or other actions, claims, suits or other proceedings against or involving any Company Plan or asserting rights or claims to benefits under any Company Plan (other than

routine claims for benefits payable in the normal course). Except as set forth in Section 4.13(c)(i) of the Company Disclosure Letter, neither the Company nor any of its Subsidiaries has any obligation for retiree healthcare or retiree life insurance benefits under any Company Plan (other than a Foreign Benefit Plan) or Collective Bargaining Agreement covering employees located in the United States other than for continuation coverage required to be provided pursuant to Section 4980B of the Code and at the sole expense of such participant. To the knowledge of the Company, neither the Company nor any of its Subsidiaries has any material obligation for retiree healthcare or retiree life insurance benefits under any Foreign Benefit Plan or Collective Bargaining Agreement covering employees located outside of the United States other than as required pursuant to applicable Law. Other than as set forth on Section 4.13(c)(ii) of the Company Disclosure Letter or as otherwise provided by applicable Law, each Company Plan that provides retiree healthcare or retiree life insurance benefits may be amended or terminated without material liability to the Company or any of its Subsidiaries at any time after the Effective Time.

Except as would not have, individually or in the aggregate, a Material Adverse Effect, none of the Company, any of its Subsidiaries or any of its or their ERISA Affiliates has incurred any liability to the Pension Benefit Guaranty Corporation which remains outstanding and unsatisfied.

(c) Prior to the Acceptance Time, the Company will promptly (and in any event within forty-eight (48) hours) notify Parent if any proposal, offer or inquiry is received by, or any discussions or negotiations are sought to be initiated or continued with, the Company in respect of any Acquisition Proposal. The Company will provide Parent promptly (and in any event within such forty-eight (48) hour period) the identity of the Person making such proposal, offer, inquiry or other contact and the material terms and conditions of any proposals or offers (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such proposal, offer, inquiry or request) and thereafter shall promptly keep Parent informed of all material developments of any such proposals, offers, inquiries, or requests (and the Company shall provide Parent with copies of any additional written materials received that revise, in any material respect, such proposals or offers, inquiries, or requests).

(d) Notwithstanding anything in Section 6.3 to the contrary, if (i) the Company receives a written Acquisition Proposal that the Company Board believes in good faith is bona fide, and (ii) the Company Board, after consultation with its financial advisors and outside legal counsel, concludes in good faith such Acquisition Proposal constitutes a Superior Proposal, then, subject to compliance with Section 8.5, the Company Board may at any time prior to the Acceptance Time, if it determines in good faith, after consultation with outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law, (x) effect a Change of Board Recommendation and/or (y) (A) in the event such Acquisition Proposal did not result from a material breach of this Section 6.3 or (B) in the event such Acquisition Proposal did result from a material breach of this Section 6.3 and on the Expiration Date occurring after such breach all Offer Conditions except the Minimum Tender Condition had been satisfied or waived, terminate this Agreement and concurrent with such termination cause the Company to enter into an Acquisition Agreement with respect to such Superior Proposal; provided, however, that the Company Board may not effect a Change of Board Recommendation pursuant to the foregoing clause (x) or terminate this Agreement pursuant to the foregoing clause (y) unless the Company has provided prior written notice to Parent specifying in reasonable detail the reasons for such action (including a description of the material terms of such Acquisition Proposal and delivering to Parent a copy of the Acquisition Agreement and other relevant documents for such Superior Proposal in the form to be entered into), at least three (3) Business Days in advance of its intention to take such action with respect to such Superior Proposal, unless there are less than three (3) Business Days prior to the then scheduled Expiration Date, in which case, the Company will provide such written notice as far in advance of the then scheduled Expiration Date as practicable (the period inclusive of all such days, the “Notice Period”) (it being understood and agreed that (i) during the Notice Period the Company shall, and shall cause its financial advisors and outside legal counsel to, negotiate with Parent in good faith (to the extent Parent desires to negotiate), (ii) the Company shall take into account all changes to the terms of this Agreement irrevocably proposed by Parent in determining whether such Acquisition Proposal continues to constitute a Superior Proposal and (iii) any amendment, in any material respect, to the terms of such Superior Proposal shall require a new notice pursuant to this Section 6.3(d) and a forty-eight (48) hour extension (from the time Parent receives such notice) of the Notice Period then applicable). After delivery of such written notice pursuant to the immediately preceding sentence, the Company shall promptly keep Parent informed of all material developments affecting the material terms of any such Superior Proposal (and the Company shall provide Parent with copies of any additional written materials received that relate to such Superior Proposals).

(e) Notwithstanding anything in Section 6.3(a) to the contrary, the Company Board may, at any time prior to the Acceptance Time, effect a Change of Board Recommendation in response to an Intervening Event if the Company Board concludes in good faith, after consultation with outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law. An “Intervening Event” means, with respect to the Company, a material event or circumstance that arises or occurs after the date of this Agreement and was not, prior to the date of this Agreement, reasonably foreseeable by the Company Board; provided, however, that in no event shall the receipt, existence or terms of an Acquisition Proposal or any matter relating thereto or consequence thereof constitute an Intervening Event.

(f) Nothing contained in this Section 6.3 will prohibit the Company Board from taking and disclosing to the shareholders of the Company a position contemplated by Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act.

(g) For purposes of this Agreement, (i) “Acquisition Proposal” means any offer or proposal made by a Person or group at any time after the date hereof that is structured to result in such Person or group to acquiring, directly or indirectly, beneficial ownership of at least twenty percent (20%) of the assets of, equity interest in, or businesses of, the Company and its Subsidiaries, taken as a whole, pursuant to a merger, consolidation or other business combination, sale of shares of capital stock, sale of assets, tender offer or exchange offer or similar transaction, including any single or multi-step transaction or series of related transactions, in each case other than the Offer and the Merger, and (ii) “Superior Proposal” means an Acquisition Proposal that if consummated would result in a Person or group owning, directly or indirectly, (a) 50% or more of all classes of equity securities of the Company or of the surviving entity in a merger involving the Company or the resulting direct or indirect parent of the Company or such surviving entity or (b) 50% or more (based on the fair market value thereof, as determined by the Company Board in good faith) of the assets of the Company and its Subsidiaries (including capital stock of the Subsidiaries of the Company, and by means of any tender offer for the capital stock of, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, binding share exchange or similar transaction involving, any Subsidiary of the Company), taken as a whole, that the Company Board has determined (after consultation with its financial advisor and outside counsel) are superior, from a financial point of view, to this Agreement, taking into account all financial, legal, regulatory and other aspects of such proposal and of this Agreement (including the relative risks of non-consummation and any changes to the terms of this Agreement irrevocably proposed by Parent to the Company, prior to the expiration of the period referred to in Section 6.3(d)(y).

Section 6.4 Employment and Employee Benefits Matters.

(a) Parent will cause the Surviving Corporation and each of its Subsidiaries, for the period commencing at the Control Time and ending on the first anniversary thereof (the “Continuation Period”), to (i) maintain for the individuals employed by the Company at the Control Time (the “Current Employees”) and who remain employees of the Surviving Corporation during the Continuation Period base compensation and target incentive compensation that is no less favorable to each Current Employee than such Current Employee’s base compensation and target incentive compensation immediately prior to the Control Time, and (ii) provide benefits that are of comparable economic value in the aggregate to the benefits provided by the Company as of immediately prior to the Control Time (excluding, for purposes of Section 6.4(a)(i) and (ii) equity and equity-based compensation, retention, stay, or transaction bonuses or similar arrangements); provided, however, that nothing in this Section 6.4 will be construed as an amendment to or prevent the amendment or termination of any particular Company Plan or employee benefit plan of Parent or any of its Subsidiaries, to the extent permissible thereunder, or interfere with the Parent’s or any of its Subsidiaries’ or the Surviving Corporation’s right or obligation to make such changes as are necessary to conform with applicable Law. Parent will cause the Surviving Corporation and each of its Subsidiaries to honor all obligations and agreements relating to 2010 Bonuses (as defined in Section 4.13(a) of the Company Disclosure Letter) as are, and to the fullest extent, set forth in Section 6.4(a) of the

Company Disclosure Letter. During the Continuation Period, Parent will cause the Surviving Corporation to pay or cause to be paid, consistent with the Company’s past practice in similar circumstances, to each Current Employee (i) who is involuntarily terminated or (ii) in the case of any employee covered by an employment, change in control, severance or similar agreement or entitlement providing for benefits upon a voluntary termination for good reason, who terminates employment voluntarily for good reason as therein defined, severance in accordance with past practices, including with respect to bonuses.

(b) Parent will, and will cause the Surviving Corporation to, cause service rendered by Current Employees prior to the Control Time to be taken into account for vesting and eligibility purposes (but not for accrual purposes, except for vacation and severance, if applicable) under employee benefit plans of Parent, the Surviving Corporation and its Subsidiaries, to the same extent as such service was taken into account under the corresponding Company Plans for those purposes; provided, that the foregoing crediting of service shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service. For the calendar year in which the Control Time occurs, Current Employees will not be subject to any eligibility requirements or pre-existing condition limitations under any employee health benefit plan of Parent, the Surviving Corporation or its Subsidiaries for any condition for which they would have been entitled to coverage under the corresponding Company Plan in which they participated prior to the Control Time except to the extent such exclusions and limitations (i) would not have been waived and (ii) were applicable to such Continuing Employee or any dependent, in each case of (i) and (ii), under the applicable Company Plan as of the Control Time. Parent will, and will cause the Surviving Corporation and its Subsidiaries, for the calendar year in which the Control Time occurs, to give such Current Employees credit under such employee benefit plans for co-payments made and deductibles and maximum out-of-pocket limitations in respect of the year in which the Control Time occurs.

(c) Nothing contained herein, expressed or implied, is intended to confer upon any Continuing Employee or any other Person any benefits under any benefit plans, programs, policies or other arrangements, including severance benefits or right to employment or continued employment with Parent, the Surviving Corporation or any of its or their Subsidiaries or Affiliates for any period by reason of this Agreement. Except as specified in clause (b) of Section 9.6, the provisions of this Agreement, in particular this Section 6.4, are solely for the benefit of the parties to this Agreement, and no current or former employee, director, or independent contractor or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement. Following the Control Time, nothing contained in this Section 6.4 shall interfere with Parent, the Surviving Corporation or any of its or their Subsidiaries’ or Affiliate’s right to terminate the employment of any employee for any reason.

Section 6.5 Directors’ and Officers’ Indemnification and Insurance.

(a) Parent will cause the Surviving Corporation’s Articles of Organization and Bylaws to contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation from liabilities of present and former directors, officers and employees of the Company than are currently provided in the Articles of Organization and Bylaws, which provisions will not be amended, repealed or otherwise modified in any manner that would

adversely affect the rights thereunder of any such individuals until six (6) years from the Effective Time, and, in the event that any Proceeding is pending or asserted or any claim made during such period, until the disposition of any such Proceeding or claim, unless such amendment, modification or repeal is required by applicable Law, in which case Parent agrees, and will cause the Surviving Corporation, to make such changes to the Articles of Organization and the Bylaws as to have the least adverse affect on the rights of the individuals referenced in this Section 6.5.

(b) Without limiting any additional rights that any Person may have under any agreement or Company Plan, from and after the Effective Time, Parent and the Surviving Corporation will, jointly and severally, indemnify and hold harmless each present (as of the Effective Time) or former officer and director of the Company (each, together with such person’s heirs, executors or administrators, an “Indemnified Party” and collectively, the “Indemnified Parties”), against all obligations to pay a judgment, settlement, penalty, and reasonable expenses incurred in connection with any Proceeding, whether civil, criminal, administrative, arbitrative or investigative, and whether formal or informal, arising out of or pertaining to any action or omission, including any action or omission in connection with the fact that the Indemnified Party is or was an officer, director, employee, fiduciary or agent of the Company or its Subsidiaries, or of another entity if such service was at the request of the Company, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under applicable Law. In the event of any such Proceeding, each Indemnified Party will be entitled to advancement of expenses incurred in the defense of the Proceeding from the Surviving Corporation or Parent (provided that any Person to whom expenses are advanced will have provided an undertaking, but only to the extent required by the MBCA, to repay such advances if it is finally determined that such Person is not entitled to indemnification). Parent’s and the Surviving Corporation’s obligations under this Section 6.5(b) shall continue in full force and effect for a period of six (6) years from the Effective Time; provided, however, that all rights to indemnification in respect of any claim asserted or made within such period shall continue until the final disposition of such claim.

(c) The Company may purchase by the Effective Time tail policies to the current directors’ and officers’ liability insurance policies maintained at such time by the Company, which tail policies (i) will be effective for a period from the Effective Time through and including the date six (6) years after the Effective Time with respect to claims arising from facts or events that existed or occurred prior to or at the Effective Time, and (ii) will contain coverage that is at least as protective to such directors and officers as the coverage provided by such existing policies; provided, however, that, without the prior written consent of Parent, the Company may not expend therefor in excess of 300% of the amount (“Annual Amount”) payable by the Company for 12 months of coverage under its existing directors’ and officers’ liability insurance policies. In the event the Company does not obtain such tail policies, then, for a period of six (6) years from the Effective Time, Parent shall maintain in effect the Company’s current directors’ and officers’ liability insurance policies in respect of acts or omissions occurring at or prior to the Effective Time, covering each Indemnified Party on terms with respect to such coverage and amounts no less favorable than those of such policies in effect on the date of this Agreement; provided, however, that Parent may substitute therefor policies of a reputable and financially sound insurance company containing terms, including with respect to coverage and amounts, no less favorable to any Indemnified Party; provided further, however, that in

satisfying their obligation under this Section 6.5(c), Parent shall not be obligated to pay for coverage for any 12-month period aggregate premiums for insurance in excess of 300% of the Annual Amount, it being understood and agreed that Parent shall nevertheless be obligated to provide such coverage as may be obtained for 300% of the Annual Amount. Parent will cause such policies to be maintained in full force and effect for their full term, and cause all obligations thereunder to be honored by the Surviving Corporation.

(d) This Section 6.5 will survive the consummation of the Merger and is intended to benefit, and will be enforceable by, any Person or entity referred to in clause (a) of this Section 6.5. The indemnification and advancement provided for in this Section 6.5 will not be deemed exclusive of any other rights to which the Indemnified Party is entitled whether pursuant to Law, contract or otherwise. If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and will not be the continuing or surviving corporation or entity resulting from such consolidation or merger or (ii) transfers all or majority of its properties and assets to any Person, then, and in each such case, proper provision will be made so that the successors and assigns of the Surviving Corporation will assume the applicable obligations set forth in this Section 6.5.

Section 6.6 Further Action; Efforts.

(a) Subject to the terms and conditions of this Agreement, prior to the Effective Time, each party will use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate the Offer, the Merger and the other transactions contemplated by this Agreement. Notwithstanding anything in this Agreement to the contrary, the parties hereto agree to (i) make all filings required by applicable foreign Antitrust Laws with respect to the Merger as promptly as practicable and in any event prior to the expiration of any applicable legal deadline, and (ii) supply as promptly as practicable any additional information and documentary material that may be requested pursuant to any Antitrust Law. The parties shall also consult and cooperate with one another, and consider in good faith the views of one another, in connection with, and provide to the other parties in advance, any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection with proceedings under or relating to any Antitrust Laws. Without limiting the foregoing, the parties hereto agree (A) to give each other reasonable advance notice of all meetings with any Governmental Entity relating to any Antitrust Laws, (B) to give each other an opportunity to participate in each of such meetings, (C) to the extent practicable, to give each other reasonable advance notice of all substantive oral communications with any Governmental Entity relating to any Antitrust Laws, (D) if any Governmental Entity initiates a substantive oral communication regarding any Antitrust Laws, to promptly notify the other party of the substance of such communication, (E) to provide each other with a reasonable advance opportunity to review and comment upon all written communications (including any analyses, presentations, memoranda, briefs, arguments, opinions and proposals) with a Governmental Entity regarding any Antitrust Laws and (F) to provide each other with copies of all written communications to or from any Governmental Entity relating to any Antitrust Laws. Any such disclosures or provision of copies by one party to the other may be made on an outside counsel basis if appropriate. Notwithstanding anything in this Agreement to the contrary, Parent agrees, and shall cause each of its Subsidiaries and Affiliates, to take any and all actions

reasonably necessary to obtain any consents, clearances or approvals (x) required under or in connection with the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended, the ▇▇▇▇▇▇▇ Act, as amended, the ▇▇▇▇▇▇▇ Act, as amended, the Federal Trade Commission Act, as amended, and any other federal, state or foreign law, regulation or decree designed to prohibit, restrict or regulate actions for the purpose or effect of monopolization or restraint of trade or the significant impediment of effective competition (collectively “Antitrust Laws”) or (y) to enable all waiting periods under applicable Antitrust Laws to expire, and to avoid or eliminate impediments under applicable Antitrust Laws asserted by any Governmental Entity, in each case, to cause the Merger to occur prior to the Outside Date, including but not limited to (1) promptly complying with or modifying any requests for additional information (including any second request) by any Governmental Entity, (2) if necessary to obtain clearance by any Governmental Entity before the Outside Date, offering, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture, license or other disposition of any and all of the capital stock, assets, rights, products or businesses of the Parent and its Subsidiaries and any other restrictions on the activities of Parent and its Subsidiaries and (3) contesting, defending and appealing any threatened or pending preliminary or permanent injunction or other order, decree or ruling or statute, rule, regulation or executive order that would adversely affect the ability of any party hereto to consummate the Offer and the Merger and taking other actions to prevent the entry, enactment or promulgation thereof; provided, however, Parent shall not be required to take any action if such action would, or would reasonably be expected to, have a material adverse impact on the Company or on Parent and its Subsidiaries, taken as a whole. Each party will bear the expenses and costs incurred by such party in connection with any competition filings and submissions which may be required by such party for the consummation of the Offer and the Merger pursuant to this Agreement.

(b) In the event that any administrative or judicial action or proceeding is instituted (or threatened to be instituted) by a Governmental Entity challenging the Offer or the Merger, each of Parent, Purchaser and the Company will cooperate in all respects with each other and will use commercially reasonable efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Offer or the Merger.

(c) Prior to the Acceptance Time, each party will use commercially reasonable efforts to obtain any consents, approvals or waivers of third parties with respect to any Permits, Environmental Permits or Contracts to which it is a party as may be necessary for the consummation of the transactions contemplated by this Agreement or required by the terms of any Contract as a result of the execution, performance or consummation of the transactions contemplated by this Agreement; provided, that in no event will any party or its Subsidiaries be required to pay, prior to the Effective Time, any fee, penalty or other consideration to any third party to obtain any consent, approval or waiver required with respect to any such Contract.

(d) To the extent the transactions contemplated by this Merger require action by the Company under the Industrial Site Recovery Act (“ISRA”) (N.J.S.A. 13:1K and N.J.A.C. 7:26B), the Company will use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable

Laws to consummate the Merger under ISRA. Parent shall cooperate in all commercially reasonable respects to facilitate compliance with ISRA.

Section 6.7 Information Statement; Post-Effective Amendment.

(a) Unless the Merger is consummated in accordance with Section 11.05 of the MBCA as contemplated by Section 2.7, promptly after the consummation of the Offer, the Company will prepare and file with the SEC the Information Statement in preliminary form as required by the Exchange Act and the rules and regulations promulgated thereunder and Parent shall prepare and file with the SEC a post-effective amendment to the Form F-4 (the “Post-Effective Amendment”) for the offer and sale of the CVRs pursuant to the Merger and in which the Information Statement will be included as a prospectus. The Information Statement and the Post-Effective Amendment will comply as to form in all material respects with applicable U.S. federal securities Laws. Parent and Purchaser will be given a reasonable opportunity to review and comment on the Information Statement prior to its filing with the SEC, and Parent will provide the Company with a reasonable opportunity to review and comment on the Post-Effective Amendment prior to the initial filing with the SEC. Parent will use commercially reasonable efforts to have the Post-Effective Amendment declared effective under the Securities Act as promptly as reasonably practicable after such filing. The Company will obtain and furnish the information required to be included in the Information Statement, and Parent will obtain and furnish the information required to be included in the Post-Effective Amendment, and each of Parent and the Company will provide the other party with, and consult with the other party regarding, any comments that may be received from the SEC or its staff with respect to the Information Statement or the Post-Effective Amendment, as the case may be, will provide the other party with a reasonable opportunity to review and comment on any amendment or supplement to the Post-Effective Amendment or Information Statement, as the case may be, and any communications, prior to making such filings or communications with the SEC and will promptly provide the other party with a copy of all such filings and communications made with the SEC. The Company will cause the Information Statement in definitive form to be mailed to the holders of Shares.

(b) If at any time prior to the Effective Time, (i) any event or change occurs with respect to the parties or any of their respective Affiliates, officers or directors, which should be set forth in an amendment of, or a supplement to, the Post-Effective Amendment or Information Statement or (ii) any information relating to the parties, or any of their respective Affiliates, officers or directors, should be discovered by any of the parties which should be set forth in an amendment or a supplement to the Post-Effective Amendment or Information Statement so that the Post-Effective Amendment or Information Statement would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, Parent or the Company, as the case may be, will file as promptly as practicable with the SEC an amendment of, or a supplement to, the Post-Effective Amendment or Information Statement and, as required by Law, disseminate the information contained in such amendment or supplement to the shareholders of the Company.

Section 6.8 Public Announcements. Each of the Company, Parent and Purchaser agrees that no public release or announcement concerning the transactions contemplated by this

Agreement will be issued by such party without the prior consent of the Company and Parent (which consent will not be unreasonably withheld or delayed), except as such release or announcement may be required by applicable Law or any rule or regulation of Nasdaq or any other stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement will use commercially reasonable efforts to allow each other party reasonable time to comment on such release or announcement in advance of such issuance, it being understood that the final form and content of any such release or announcement, to the extent so required, will be at the final discretion of the disclosing party. The restrictions of this Section 6.8 will not apply to communications by the Company or Parent regarding an Acquisition Proposal or a Change of Board Recommendation.

Section 6.9 Approval of Compensation Actions. Prior to the Acceptance Time, the Compensation Committee of the Company Board will take all such actions as may be required to approve, as an employment compensation, severance or other employee benefit arrangement in accordance with the requirements of Rule 14d-10(d)(2) under the Exchange Act and the instructions thereto, any and all Compensation Actions taken after January 1, 2010 and prior to the Acceptance Time that have not already been so approved. For the purposes of this Agreement, “Compensation Action” means any (a) granting by the Company or its Subsidiaries to any present or former director or officer of any increase in compensation or benefits or of the right to receive any severance or termination compensation or benefit; (b) entry by the Company or its Subsidiaries into any employment, consulting, indemnification, termination, change of control, non-competition or severance agreement with any present or former director or officer, or any approval, amendment or modification of any such agreement; or (c) approval of, amendment to or adoption of any Company Plan.

Section 6.10 Conduct of Parent and Purchaser. Subject to applicable Law, neither Parent nor Purchaser will take (or permit its Affiliates to take) any action that, or fail to take any commercially reasonable action, for which the failure to take such action, is intended to, or would reasonably be expected to, individually or in the aggregate, result in any Offer Conditions or the conditions to the Merger not being satisfied or prevent, materially delay or materially impede the ability of Parent and Purchaser to consummate the Offer, the Merger or the other transactions contemplated by this Agreement.

Section 6.11 No Control of the Company’s Business. Nothing contained in this Agreement will give Parent, directly or indirectly, the right to control or direct the Company’s or its Subsidiaries’ operations prior to the Control Time. Prior to the Control Time, the Company will exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

Section 6.12 Operations of the Purchaser. Prior to the Effective Time, Purchaser will not engage in any other business activities and will not have incurred any liabilities or obligations other than as contemplated herein.

Section 6.13 Ownership of Company Securities. Prior to the Acceptance Time, none of Parent or Purchaser or their respective Subsidiaries will own (directly or indirectly, beneficially or of record) any Company Securities other than an aggregate of 100 Shares, and none of Parent,

Purchaser or their respective Affiliates will hold any rights to acquire any Company Securities except pursuant to this Agreement.

Section 6.14 Employee Information and Consultation. The Company, its Subsidiaries and each of its and their Affiliates, as applicable, shall inform and/or consult with, as applicable, all labor unions, labor organizations, works councils and any other employee representative bodies with respect to the terms of any Collective Bargaining Agreement or applicable Laws in connection with this Agreement and the transactions contemplated hereby, and shall take all other necessary and appropriate actions in connection with employees covered thereby as may be required pursuant to applicable Laws.

Section 6.15 Shareholder Litigation. The Company shall give Parent the opportunity to participate in, and if Parent so elects the Company and Parent shall reasonably cooperate with respect to, the defense or settlement of any shareholder litigation against the Company and/or its directors or executive officers relating to the Offer, this Agreement or any transaction contemplated herein, whether commenced prior to or after the execution and delivery of this Agreement, and shall not settle or offer to settle any such litigation without the prior written consent of Parent, except for, after consultation with Parent, any settlement or offer to settle that involves solely additional disclosure with respect to the Company and its Subsidiaries.

Section 6.16 Financing Cooperation. Prior to the Acceptance Time, the Company shall provide, and shall cause its Subsidiaries to provide, and shall use its commercially reasonable efforts to cause its and their officers, employees and advisors, including legal and accounting, to provide reasonable cooperation requested by Parent in connection with the arrangement of any debt or equity financing transaction by Parent in connection with the Merger (the “Prospective Financing”), including using its commercially reasonable efforts to (a) provide financial and other relevant information regarding the Company and its Subsidiaries that is reasonably necessary and cooperate in the preparation of pro forma financial information for the Merger (including information to be used in the preparation of an information package, offering memorandum, prospectus, prospectus supplement or similar document regarding the business, assets, operations, financial projections and prospects of Parent and the Company customary for such financing or reasonably necessary for the completion of the Prospective Financing) as may be required to obtain the Prospective Financing, (b) cooperate with the marketing efforts for the Prospective Financing (including consenting to the reasonable use of the logos of the Company and its Subsidiaries), (c) participate as appropriate in meetings, presentations, road shows, drafting sessions, and sessions with the rating agencies as are reasonably necessary to consummate the Prospective Financing, (d) assist Parent and its financing sources in the amendment or termination of, or in obtaining any relevant waiver from the lenders or counterparties of the Company or any of its Subsidiaries in relation to, any of the Company’s or any of its Subsidiaries’ existing credit agreements, currency or interest hedging agreements, or other agreements (including, for the avoidance of doubt, any arrangements creating security interests), in each case, on terms satisfactory to Parent and that are reasonably requested by Parent in connection with the Prospective Financing and conditioned upon the occurrence of the Acceptance Time, in each case it being understood and agreed that information and documents provided by the Company and its Subsidiaries may be delivered to agents and lenders and their respective representatives and (e) subject to the appropriate confidentiality undertakings, cooperate reasonably with Parent’s financing sources’ or underwriters’, as applicable, due

diligence. Notwithstanding the foregoing, (i) no obligation of the Company or any of its Subsidiaries related to any financing (other than cooperation pursuant to this Section 6.16) will be effective prior to the Effective Time, (ii) nothing herein shall require such cooperation to the extent it would interfere, in an unreasonable manner, with the business or operations of the Company or its Subsidiaries, and (iii) neither the Company nor any of its Subsidiaries will be required to pay any commitment fee or similar fee or incur any liability with respect to any financing prior to the Effective Time. Parent (A) will promptly, upon request of the Company, reimburse the Company for all out-of-pocket costs (including attorneys’ fees) incurred by the Company, any of its Subsidiaries or its Representatives in connection with the cooperation of the Company and its Subsidiaries requested by Parent pursuant to this Section 6.16, (B) acknowledges and agrees that the Company, its Subsidiaries and Representatives will not have any responsibility for, or incur any liability to any Person under the Prospective Financing prior to the Effective Time and (C) will indemnify and hold harmless the Company, its Subsidiaries and its Representatives from and against any and all losses, damages, claims, costs or expenses to the extent suffered or incurred in connection with the arrangement of the Prospective Financing pursuant to this Section 6.16 and any information used in connection therewith, except to the extent that such losses, damages, claims, costs or expenses resulted from or arose out of the willful misconduct of, or information provided by, the Company or any of its Subsidiaries. Notwithstanding anything to the contrary in this Agreement, the Company agrees that, prior to the Acceptance Time, the Company shall either (1) deliver to Parent a fully executed and effective waiver under the Credit Agreement, in form and substance reasonably satisfactory to Parent, waiving any Default (as defined in the Credit Agreement) or Event of Default (as defined in the Credit Agreement) in connection with the consummation of the Offer, the Merger and the other transactions contemplated by this Agreement or (2) repay all amounts owed under the Credit Agreement, terminate the Credit Agreement and provide evidence, in form and substance reasonably satisfactory to Parent, of such termination.

Section 6.17 Outstanding Stock Purchase Rights. From the date of this Agreement until the Effective Time, the Company shall use commercially reasonable efforts to contact the holders of all Assumed Preferred Stock Purchase Rights (as defined in the Securities Purchase Agreement), and obtain the written consent of each such holder to effect an immediate net exercise of all such rights held by such holder.

ARTICLE VIII
TERMINATION, AMENDMENT AND WAIVER

Section 8.1 Termination by Mutual Agreement. This Agreement may be terminated and the Offer and the Merger may be abandoned at any time prior to the Effective Time, notwithstanding approval thereof by the holders of the Shares, by mutual written consent of Parent and the Company.

Section 8.2 Termination by Either Parent or the Company. This Agreement may be terminated and the Offer and the Merger may be abandoned by Parent or the Company at any time prior to the Effective Time:

(a) if the Acceptance Time shall not have occurred on or prior the close of business on August 16, 2011 (the “Outside Date”); provided, however, that a party shall not be permitted to terminate this Agreement pursuant to this Section 8.2(a) in the event that the failure of the Acceptance Time to occur on or prior to the Outside Date is primarily due to the failure of such party (or a Subsidiary of such party) to fulfill any of its obligations under this Agreement;

(b) if the Offer (as it may have been extended pursuant to Section 1.1) is terminated or withdrawn pursuant to its terms and the terms of this Agreement without any Shares being purchased thereunder; provided however, that a party shall not be permitted to terminate this Agreement pursuant to this Section 8.2(b) in the event that the failure of the Shares to be purchased is primarily due to the failure of such party (or a Subsidiary of such party) to fulfill any of its obligations under this Agreement; or

(c) notwithstanding approval of this Agreement by the holders of Shares, if any court of competent jurisdiction or other Governmental Entity has issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the Offer or the Merger and such order, decree, ruling or other action has become final and nonappealable; provided, however, that the terms of this Section 8.2 will not be available to any party unless such party will have used commercially reasonable efforts to oppose any such order, decree, ruling or other action or to have the same vacated or made inapplicable to the Offer or the Merger.

Section 8.3 Termination by the Company. This Agreement may be terminated and the Merger may be abandoned by the Company at any time prior to the Acceptance Time:

(a) if (i) Purchaser fails to commence the Offer in violation of Section 1.1 hereof, or (ii) there has been a breach or inaccuracy of any representation, warranty, covenant or agreement on the part of Parent or Purchaser contained in this Agreement, which breach or inaccuracy would give rise to a Purchaser Material Adverse Effect and which breach or

inaccuracy is not capable of being cured within twenty (20) days following receipt by Parent or Purchaser of written notice of such breach or inaccuracy or, if such breach or failure is capable of being cured within such period, it has not been cured within such period, provided, however, that the failure of any such condition to be capable of satisfaction is not the result of a material breach of this Agreement by the Company; or

(b) in accordance with, and subject to the terms and conditions of, Section 6.3(d).

Section 8.4 Termination by Parent. This Agreement may be terminated and the Merger may be abandoned by Parent at any time prior to the Acceptance Time:

(a) if the Company has breached or failed to perform, in any material respect, any of its representations, warranties, covenants or agreements set forth in this Agreement, which breach or failure to perform (x) would give rise to the failure of a condition set forth in Annex I of this Agreement and (y) is not capable of being cured within twenty (20) days following receipt by the Company of written notice of such breach or inaccuracy or, if such breach or failure is capable of being cured within such period, it has not been cured within such period, provided, however, that the failure of any such condition to be capable of satisfaction is not the result of a material breach of this Agreement by Parent or Purchaser;

(b) within five (5) Business Days of a Change of Board Recommendation;

(c) if the Company Board shall have failed to reaffirm its recommendation of this Agreement and the Offer within three (3) Business Days after receipt of any written request to do so from Parent (which request may only be made following public disclosure of an Acquisition Proposal and may only be made one time with respect to any Acquisition Proposal; provided that Parent may make such a request with respect to any Acquisition Proposal whenever it is amended in any material respect); or

(d) if the Company shall have intentionally breached, in any material respect, any of its obligations under Section 6.3.

Section 8.5 Effect of Termination.

(a) Any termination of this Agreement by Parent pursuant to this ARTICLE VIII will also constitute an effective termination by Purchaser.

(b) Except as provided in Section 8.5(c), in the event of termination of this Agreement and the abandonment of the Merger pursuant to this ARTICLE VIII, this Agreement (other than Section 6.2(b), ARTICLE VIII and ARTICLE IX) will become void and of no effect with no liability on the part of any party (or of any of its Representatives); provided, however, that no such termination will relieve any Person of any liability for damages resulting from intentional breach of this Agreement.

(i) this Agreement is terminated by the Company pursuant to Section 8.3(b); or

(ii) this Agreement is terminated by Parent either (x) pursuant to Section 8.4(b) or Section 8.4(c) or (y) pursuant to Section 8.2(a) solely as a result of the failure of the Offer Conditions set forth in Paragraph 2(b) through (e) of Annex I to this Agreement to be satisfied or Section 8.4(d), and, in the case of clause (y) above, (A) at any time on or after the date hereof and prior to such termination a third party has made, or has announced an intention to make, an Acquisition Proposal that has not been withdrawn prior to termination, and (B) within twelve (12) months after the date of such termination, the Company enters into a definitive agreement with respect to or consummates any transaction specified in the definition of “Acquisition Proposal”;

then in any such case, the Company will pay Parent a termination fee of $575,000,000 (the “Termination Fee”), by wire transfer of immediately available funds to the account or accounts designated by Parent. Any payment required to be made (1) pursuant to clause (i) of this Section 8.5(c) will be paid concurrently with the termination of this Agreement and (2) pursuant to clause (ii) of this Section 8.5(c) will be paid on the date of consummation with such third party of a transaction specified in the definition of “Acquisition Proposal.” For the avoidance of doubt, the Company will not be required to pay the Termination Fee more than once. For purposes of this Section 8.5(c), “Acquisition Proposal” will have the meaning ascribed thereto in Section 6.3(g), except that references in the definition to “twenty percent (20%)” will be replaced by “fifty percent (50%).”

(d) If Parent receives a fee pursuant to Section 8.5(c), the collection of such fee will be the sole and exclusive remedy of Parent and Purchaser in respect of any breach of, or inaccuracy contained in, the Company’s covenants, agreements, representations or warranties in this Agreement.

(e) The Company acknowledges that the agreements contained in Section 8.5(c) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent or Purchaser would not have entered into this Agreement.

Section 8.6 Expenses. Except as otherwise specifically provided herein, each party will bear its own expenses in connection with this Agreement and the transactions contemplated hereby.

Section 8.7 Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of their respective boards of directors at any time prior to the Effective Time, whether before or after approval of this Agreement by the holders of Shares; provided, however, that, (a) after Purchaser purchases any Shares pursuant to the Offer, no amendment will be made that decreases the Merger Consideration, and (b) after approval of this Agreement by the holders of Shares, no amendment may be made that (i) is prohibited by Section 11.02(e) of the MBCA or (ii) by Law or any applicable rule or regulation of any stock exchange requires the further approval of the holders of Shares without such further approval. This Agreement may not be amended except by an instrument in writing signed by the parties hereto.

Section 8.8 Waiver. At any time prior to the Effective Time, the Company, on the one hand, and Parent and Purchaser, on the other hand, may (a) extend the time for the performance of any of the obligations or other acts of the other, (b) waive any inaccuracies in the representations and warranties of the other contained herein or in any document delivered pursuant hereto, and (c) subject to the requirements of applicable Law, waive compliance by the other with any of the agreements or conditions contained herein, except that the Minimum Tender Condition and the CVR Condition may only be waived by Purchaser with the prior written consent of the Company. Any such extension or waiver will be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby. The failure of any party to assert any rights or remedies will not constitute a waiver of such rights or remedies.

ARTICLE IX
GENERAL PROVISIONS

Section 9.1 Non-Survival of Representations, Warranties, Covenants and Agreements. None of the representations, warranties, covenants and agreements in this Agreement or in any instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such representations, warranties, covenants and agreements, will survive the Effective Time, except for (a) those covenants and agreements contained herein that by their terms apply or are to be performed in whole or in part after the Effective Time and (b) this ARTICLE IX.

(b) any applicable waiting period under the Antitrust Laws of the jurisdictions listed on Annex III, in respect of the transactions contemplated by this Agreement has expired or been terminated; and

(c) the representations and warranties of the Company contained in Section 4.11(b) and Section 4.21 are not true and correct in all respects;

(d) the representations and warranties of the Company contained in Section 4.3, Section 4.4(a) and Section 4.22 of the Merger Agreement that (x) are not made as of a specific date were not true and correct (except for any de minimis inaccuracy) as of the Expiration Date, as though made on and as of the Expiration Date and (y) are made as of a specific date are not true and correct (except for any de minimis inaccuracy) as of such date;

(f) there is pending a Proceeding (other than an inquiry) by any Governmental Entity challenging or seeking to restrain or prohibit the consummation of the Offer, the Merger or the other transactions contemplated thereby, in which such Governmental Entity, in the reasonable determination of Parent, has a substantial likelihood of success and which reasonably would be expected to have a material adverse impact on Parent and the Company and its Subsidiaries taken as a whole;

(g) since the date of the Merger Agreement, there has occurred a Material Adverse Effect; or

(a) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

(b) Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company.

(c) Any certificate, statement or opinion of an officer of the Company or of counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of or representations by an accountant or firm of accountants in the employ of the Company. Any certificate or opinion of any independent firm of public accountants filed with the Trustee shall contain a statement that such firm is independent.

(d) Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this CVR Agreement, they may, but need not, be consolidated and form one instrument.

SECTION 1.4 Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this CVR Agreement to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this CVR Agreement and (subject to Section 4.1) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 1.4. The Company may set a record date for purposes of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under this CVR Agreement, which date shall be no greater than ninety (90) days and no less than ten (10) days prior to the date of such vote or consent to any action by vote or consent authorized or permitted under this CVR Agreement. If not previously set by the Company, (i) the record date for determining the Holders entitled to vote at a meeting of the Holders shall be the date preceding the date notice of such meeting is mailed to the Holders, or if notice is not given, on the day next preceding the day such meeting is held, and (ii) the record date for determining the Holders entitled to consent to any action in writing without a meeting 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 Company. If a record date is fixed, those Persons who were Holders of Securities at such record date (or their duly designated proxies), and only those Persons, shall be entitled to take such action by vote or consent or, except with respect to clause (d) below, to revoke any vote or consent previously given, whether or not such Persons continue to be Holders after such record date. No such vote or consent shall be valid or effective for more than one hundred twenty (120) days after such record date.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner which the Trustee deems sufficient.

(c) The ownership of Securities shall be proved by the Security Register. Neither the Company nor the Trustee nor any Agent of the Company or the Trustee shall be affected by any notice to the contrary.

(d) At any time prior to (but not after) the evidencing to the Trustee, as provided in this Section 1.4, of the taking of any action by the Holders of the Securities specified in this CVR Agreement in connection with such action, any Holder of a Security the serial number of which is shown by the evidence to be included among the serial numbers of the Securities the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Section 1.4, revoke such action so far as concerns such Security. Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Security shall bind every future Holder of the same Security or the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, suffered or omitted to be done by the Trustee, any Paying Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

SECTION 1.5 Notices, etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this CVR Agreement to be made upon, given or furnished to, or filed with:

(a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed, in writing, to or with the Trustee at its Corporate Trust Office; or

(b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder if in writing and mailed, first-class postage prepaid, to the Company addressed to it at [Company address], Attention: [•], or at any other address previously furnished in writing to the Trustee by the Company.

SECTION 1.6 Notice to Holders; Waiver.

(a) Where this CVR Agreement provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the Holder’s address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this CVR Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(b) In case by reason of the suspension of regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event as required by any provision of this CVR Agreement, then any method of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

SECTION 1.7 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof which is required to be included in this CVR Agreement by any of the provisions of the Trust Indenture Act, such required provision shall control.

SECTION 1.8 Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 1.9 Benefits of Agreement. Nothing in this CVR Agreement or in the Securities, express or implied, shall give to any Person (other than the Parties hereto and their successors hereunder, any Paying Agent and the Holders) any benefit or any legal or equitable right, remedy or claim under this CVR Agreement or under any covenant or provision herein contained, all such covenants and provisions being for sole benefit of the Parties hereto and their successors, any Paying Agent and of the Holders.

SECTION 1.10 Governing Law.

EACH OF THE COMPANY, THE TRUSTEE AND EACH OF THE HOLDERS BY THEIR ACCEPTANCE OF THE SECURITIES, HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK IN RESPECT OF ALL CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT OR TORT) THAT MAY BE BASED UPON, ARISE OUT OF OR RELATE TO THIS CVR AGREEMENT, OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS CVR AGREEMENT (INCLUDING ANY CLAIM OR CAUSE OF ACTION BASED UPON, ARISING OUT OF OR RELATED TO ANY REPRESENTATION OR WARRANTY MADE IN OR IN CONNECTION WITH THIS CVR AGREEMENT OR AS AN INDUCEMENT TO ENTER INTO THIS CVR AGREEMENT), OR THE SECURITIES, AND IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, JURISDICTION OF THE AFORESAID COURTS. EACH OF THE COMPANY AND THE TRUSTEE AGREES THAT PROCESS

EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT, BY WAY OF MOTION, AS A DEFENSE, COUNTERCLAIM OR OTHERWISE, IN ANY ACTION OR PROCEEDING WITH RESPECT TO THIS CVR AGREEMENT (A) THE DEFENSE OF SOVEREIGN IMMUNITY, (B) ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF THE ABOVE-NAMED COURTS FOR ANY REASON OTHER THAN THE FAILURE TO SERVE PROCESS IN ACCORDANCE WITH THIS SECTION 1.10, (C) THAT IT OR ITS PROPERTY IS EXEMPT OR IMMUNE FROM JURISDICTION OF ANY SUCH COURT OR FROM ANY LEGAL PROCESS COMMENCED IN SUCH COURTS (WHETHER THROUGH SERVICE OF NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OF JUDGMENT, EXECUTION OF JUDGMENT OR OTHERWISE), AND (D) TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW THAT (I) THE SUIT, ACTION OR PROCEEDING IN SUCH COURT IS BROUGHT IN AN INCONVENIENT FORUM, (II) THE VENUE OF SUCH SUIT, ACTION OR PROCEEDING IS IMPROPER AND (III) THIS CVR AGREEMENT, OR THE SUBJECT MATTER HEREOF, MAY NOT BE ENFORCED IN OR BY SUCH COURTS.

SECTION 1.11 Legal Holidays. In the event that a Payment Date shall not be a Business Day, then (notwithstanding any provision of this CVR Agreement or the Securities to the contrary) payment on the Securities need not be made on such date, but may be made, without the accrual of any interest thereon, on the next succeeding Business Day with the same force and effect as if made on such Payment Date.

SECTION 1.12 Separability Clause. In the event any provision in this CVR Agreement or in the CVRs shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 1.13 No Recourse Against Others. A director, officer or employee, as such, of the Company or an Affiliate of the Company or the Trustee shall not have any liability for any obligations of the Company or the Trustee under the Securities or this CVR Agreement or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

SECTION 1.14 Counterparts. This CVR Agreement shall be signed in any number of counterparts with the same effect as if the signatures to each counterpart were upon a single instrument, and all such counterparts together shall be deemed an original of this CVR Agreement.

(j) Except as provided in this CVR Agreement (including, without limitation, Section 7.6), none of the Company or any of its Affiliates shall have any right to set off any amounts owed or claimed to be owed by any Holder to any of them against such Holder’s Securities or any CVR Payment or other amount payable to such Holder in respect of such Securities.

Notwithstanding the satisfaction and discharge of this CVR Agreement, the obligations of the Company under Section 4.7(c) shall survive.

SECTION 3.2 Registrable Form. The Securities shall be issuable only in registered form.

SECTION 3.3 Execution, Authentication, Delivery and Dating.

(a) The Securities shall be executed on behalf of the Company by its Chief Executive Officer or any other person duly authorized to act on behalf of the Company for such purpose or any general purpose, but need not be attested. The signature of any of these persons on the Securities may be manual or facsimile.

(b) Securities bearing the manual or facsimile signatures of individuals who were, at the time of execution, the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

(c) At any time and from time to time after the execution and delivery of this CVR Agreement, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee, in accordance with such Company Order, shall authenticate and deliver such Securities as provided in this CVR Agreement and not otherwise.

(d) Each Security shall be dated the date of its authentication.

(e) No Security shall be entitled to any benefit under this CVR Agreement or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee, by manual or facsimile signature of an authorized officer, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this CVR Agreement.

SECTION 3.4 Temporary Securities.

(a) Pending the preparation of definitive Securities, the Company may execute, and upon Company Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of this CVR Agreement as may be appropriate. Every temporary Security shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities.

(b) If temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 7.2, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like amount of definitive Securities. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this CVR Agreement as definitive Securities.

SECTION 3.5 Registration, Registration of Transfer and Exchange.

(a) The Company shall cause to be kept at the office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 7.2 being herein sometimes referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby initially appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided.

(b) Upon surrender for registration of transfer of any Security at the office or agency of the Company designated pursuant to Section 7.2, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new CVR Certificates representing the same aggregate number of CVRs represented by the CVR Certificate so surrendered that are to be transferred and the Company shall execute and the Trustee shall authenticate and deliver, in the name of the transferor, one or more new CVR Certificates representing the aggregate number of CVRs represented by such CVR Certificate that are not to be transferred.

(c) At the option of the Holder, CVR Certificates may be exchanged for other CVR Certificates that represent in the aggregate the same number of CVRs as the CVR Certificates surrendered at such office or agency. Whenever any CVR Certificates are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the CVR Certificates which the Holder making the exchange is entitled to receive.

(d) All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same rights, and entitled to the same benefits under this CVR Agreement, as the Securities surrendered upon such registration of transfer or exchange.

(e) Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Security Registrar) be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

(f) No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any documentary, stamp or similar tax or other similar governmental charge payable in connection with any registration of transfer or exchange of Securities, other than (i) exchanges pursuant to Sections 3.4, 3.6 or 6.6 not involving any transfer or (ii) transfers pursuant to Article 10.

SECTION 3.6 Mutilated, Destroyed, Lost and Stolen Securities.

(a) If (i) any mutilated Security is surrendered to the Trustee, or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee an affidavit of loss in respect of such Security, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon delivery of a Company Order, the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new CVR Certificate of like tenor and amount of CVRs, bearing a number not contemporaneously outstanding.

(b) In case any such mutilated, destroyed, lost or stolen Security has become or is to become finally due and payable within fifteen (15) days, the Company in its discretion may, instead of issuing a new CVR Certificate, pay to the Holder of such Security on the applicable Payment Date, as the case may be, all amounts due and payable with respect thereto.

(c) Every new Security issued pursuant to this Section 3.6 in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this CVR Agreement equally and proportionately with any and all other Securities duly issued hereunder.

(d) The provisions of this Section 3.6 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.7 Payments with Respect to CVR Certificates. Payment of any amounts pursuant to the CVRs shall be made in such coin or currency of the United States of America as at the time is legal tender for the payment of public and private debts. The Company may, at its option, pay such amounts by wire transfer or check payable in such money.

SECTION 3.8 Persons Deemed Owners. Prior to the time of due presentment for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payment on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.9 Cancellation. All Securities surrendered for payment, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company shall promptly deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company has acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 3.9, except as expressly permitted by this CVR Agreement. All cancelled Securities held by the Trustee shall be destroyed and a certificate of destruction shall be issued by the Trustee to the Company, unless otherwise directed by a Company Order.

SECTION 3.10 CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of Failure Purchase Offer as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a Failure Purchase Offer and that reliance may be placed only on the other identification numbers printed on the Securities, and any such Failure Purchase Offer shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

ARTICLE 4

THE TRUSTEE

SECTION 4.1 Certain Duties and Responsibilities.

(a) With respect to the Holders, the Trustee, prior to the occurrence of a Breach (as defined in Section 8.1) with respect to the Securities and after the curing or waiving of all Breaches which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this CVR Agreement and no implied covenants shall be read into this CVR Agreement against the Trustee. In case a Breach with respect to the Securities has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this CVR Agreement, and use the same degree of care and skill in their exercise, as a reasonably prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

(b) In the absence of bad faith on its part, prior to the occurrence of a Breach and after the curing or waiving of all such Breaches which may have occurred, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee which conform to the requirements of this CVR Agreement; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this CVR Agreement.

(c) No provision of this CVR Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that (i) this Subsection (c) shall not be construed to limit the effect of Subsections (a) and (b) of this Section 4.1; (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 8.9 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this CVR Agreement.

(d) Whether or not therein expressly so provided, every provision of this CVR Agreement relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 4.1.

SECTION 4.2 Certain Rights of Trustee. Subject to the provisions of Section 4.1, including without limitation, the duty of care that the Trustee is required to exercise upon the occurrence of a Breach:

(a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties and the Trustee need not investigate any fact or matter stated in the document;

(c) whenever in the administration of this CVR Agreement the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate and the Trustee shall not be liable for any action it takes or omits to take in good faith reliance thereon or an Opinion of Counsel;

(d) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this CVR Agreement at the request or direction of any of the Holders pursuant to this CVR Agreement, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document, but the Trustee in its discretion may make such further inquiry or investigation into such facts or matters as it may see fit, and if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, as necessary for such inquiry or investigation;

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any case, (A) the Company, by a Board Resolution or action of the Chief Executive Officer, may remove the Trustee, or (B) the Holder of any Security who has been a bona fide Holder of a Security for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

If, within one (1) year after any removal by the Holders of at least a majority of the Outstanding CVRs, a successor Trustee shall be appointed by act of the Holders of at least a majority of the Outstanding CVRs delivered to the Company and the retiring Trustee the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with Section 4.11, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders of the Securities and accepted appointment within sixty (60) days after the retiring Trustee tenders its resignation or is removed, the retiring Trustee may, or, the Holder of any Security who has been a bona fide Holder for at least six (6) months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. If the Company fails to send such notice within ten (10) days after acceptance of appointment by a successor Trustee, it shall not be a breach hereunder but the successor Trustee shall cause the notice to be mailed at the expense of the Company.

SECTION 4.11 Acceptance of Appointment of Successor.

(a) Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the

rights, powers, trusts and duties of the retiring Trustee; but, upon request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion, sale or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities; and such certificate shall have the full force which it is anywhere in the Securities or in this CVR Agreement provided that the certificate of the Trustee shall have; provided that the right to adopt the certificate of authentication of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 4.13 Preferential Collection of Claims Against Company. If and when the Trustee shall be or shall become a creditor, directly or indirectly, secured or unsecured, of the Company (or any other obligor upon the Securities), excluding any creditor relationship set forth in Section 311(b) of the Trust Indenture Act, if applicable, the Trustee shall be subject to the applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

SECTION 7.6 Audits.

(a) Upon the written request of the Acting Holders (but no more than once during any calendar year), and upon reasonable notice, the Company shall provide an independent certified public accounting firm of nationally recognized standing jointly agreed upon by the Acting Holders and the Company (failing agreement on which each shall designate an independent public accounting firm of its own selection, which firms shall in turn appoint an independent public accounting firm for such purpose) (the “Independent Accountant”) with access during normal business hours to such of the records of the Company as may be reasonably necessary to verify the accuracy of the statements set forth in the Product Sales Statements and the figures underlying the calculations set forth therein for any period within the preceding three (3) years that has not previously been audited in accordance with this Section 7.6.

to the Acting Holders any matters directly related to their findings and shall disclose whether it has determined that any statements set forth in the Product Sales Statements are incorrect. The Independent Accountant shall provide the Company with a copy of all disclosures made to the Acting Holders. This covenant shall survive the termination of this CVR Agreement for a period of one (1) year.

(e) The Company shall not, and shall cause its Affiliates not to, enter into any license or distribution agreement with any third party (other than the Company or its Affiliates) with respect to any Product unless such agreement contains provisions that would allow any Independent Accountant appointed pursuant to this Section 7.6 such access to the records of the other party to such license or distribution agreement as may be reasonably necessary to perform its duties pursuant to this Section 7.6; provided that the Company and its Affiliates shall not be required to amend any Existing Licenses. The Parties agree that, if the Company or its Affiliates have exercised audit rights under any license or distribution agreement prior to the Acting Holders’ request for an audit under this Section 7.6 and under such license or distribution agreement the Company and its Affiliates cannot request another audit, the results of the

Company’s prior audit of such licensee or distributor shall be used for purposes of the audit requested by the Acting Holders under this Section 7.6 and that the Company shall not have any further obligation to provide access to an Independent Accountant with respect to such licensee until such time as the Company may again exercise its rights of audit under the license agreement with such licensee.

ARTICLE 8

REMEDIES OF THE TRUSTEE AND HOLDERS IN THE EVENT OF BREACH

SECTION 8.1 Breach Defined; Waiver of Breach. “Breach” with respect to the Securities, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Breach and whether it shall be voluntary or involuntary or be effected by operation of Law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(a) failure to pay all or any part of any CVR Payment after a period of ten (10) Business Days after such CVR Payment shall become due and payable on a Payment Date or otherwise; or

(b) material breach in the performance, or breach in any material respect, of any covenant or warranty of the Company in respect of the Securities (other than a covenant or warranty in respect of the Securities, a breach in whose performance or other breach is elsewhere in this Section 8.1 specifically dealt with), and continuance of such breach for a period of ninety (90) days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Acting Holders, a written notice specifying such breach and requiring it to be remedied and stating that such notice is a “Notice of Breach” hereunder; or

(c) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar Law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the

Company or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of ninety (90) consecutive days; for the avoidance of doubt, a mandataire ad hoc or a conciliateur or any person having a similar position may be appointed upon request of the Company, without constituting a Breach under this CVR Agreement; or

(d) the Company shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar Law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such Law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property, or make any general assignment for the benefit of creditors; for the avoidance of doubt, a mandataire ad hoc or a conciliateur or any person having a similar position may be appointed upon request of the Company, without constituting a Breach under this CVR Agreement.

Except where authorization and/or appearance of each of the Holders is required by applicable Law, if a Breach described above occurs and is continuing, then either the Trustee by notice in writing to the Company, or the Trustee upon the written request of the Acting Holders by notice in writing to the Company and to the Trustee, shall bring suit to protect the rights of the Holders, including to obtain payment for any amounts then due and payable, which amounts shall bear interest at the Breach Interest Rate from the date such amounts were due and payable until payment is made to the Trustee.

The foregoing provisions, however, are subject to the condition that if, at any time after the Trustee shall have begun such suit, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all amounts which shall have become due and payable (with interest upon such overdue amount at the Breach Interest Rate to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred and all advances made, by the Trustee, and if any and all Breaches under this CVR Agreement shall have been cured, waived or otherwise remedied as provided herein, then and in every such case Holders of at least a majority of the Outstanding CVRs, by Act of said Holders delivered to the Company and the Trustee, may waive all breaches with respect to the Securities, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent breach or shall impair any right consequent thereof.

SECTION 8.2 Collection by the Trustee; the Trustee May Prove Payment Obligations. The Company covenants that in the case of any failure to pay all or any part of the Securities when the same shall have become due and payable, whether at a Payment Date or otherwise, then upon demand of the Trustee, the Company shall pay to the Trustee for the benefit of the Holders of the Securities the whole amount that then shall have become due and payable on all Securities (with interest from the date due and payable to the date of such payment upon the overdue amount at the Breach Interest Rate); and in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor Trustee, their respective agents, attorneys and counsel, and any

expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of its negligence or bad faith.

The Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this CVR Agreement or in aid of the exercise of any power granted herein, or to enforce any other remedy.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at Law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon such Securities and collect in the manner provided by Law out of the property of the Company or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to be payable.

In any judicial proceedings relative to the Company or other obligor upon the Securities, irrespective of whether any amount is then due and payable with respect to the Securities, the Trustee is authorized:

(a) to file and prove a claim or claims for the whole amount owing and unpaid in respect of the Securities, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of negligence or bad faith) and of the Holders allowed in any judicial proceedings relative to the Company or other obligor upon the Securities, or to their respective property;

(b) unless prohibited by and only to the extent required by applicable Law, to vote on behalf of the Holders in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or person performing similar functions in comparable proceedings; and

(c) to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Holders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Holders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of its negligence or bad faith, and all other amounts due to the Trustee or any predecessor

Trustee pursuant to Section 4.7. To the extent that such payment of reasonable compensation, expenses, disbursements, advances and other amounts out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, moneys, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or safeguard arrangement or otherwise.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Holder any plan of reorganization, safeguard arrangement, adjustment or composition affecting the Securities (including in the context of any amicable proceeding as mandat ad hoc and conciliation), or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person.

All rights of action and of asserting claims under this CVR Agreement, or under any of the Securities, may be enforced by the Trustee without the possession of any of the Securities or the production thereof and any trial or other proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders.

In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this CVR Agreement to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders, and it shall not be necessary to make any Holders of such Securities parties to any such proceedings (unless required by applicable Law).

SECTION 8.3 Application of Proceeds. Any monies collected by the Trustee pursuant to this Article 8 in respect of any Securities shall be applied in the following order at the date or dates fixed by the Trustee upon presentation of the several Securities in respect of which monies have been collected and stamping (or otherwise noting) thereon the payment in exchange for the presented Securities if only partially paid or upon surrender thereof if fully paid:

FIRST: To the payment of costs and expenses in respect of which monies have been collected, including reasonable compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of its negligence or willful misconduct, and all other amounts due to the Trustee or any predecessor Trustee pursuant to Section 4.7;

SECOND: To the payment of the whole amount then owing and unpaid upon all the Securities, with interest at the Breach Interest Rate on all such amounts, and in case such monies shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities, then to the payment of such amounts without preference or priority of any security over any other Security, ratably to the aggregate of such amounts due and payable; and

THIRD: To the payment of the remainder, if any, to the Company or any other person lawfully entitled thereto.

SECTION 8.4 Suits for Enforcement. In case a Breach has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this CVR Agreement by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights (unless authorization and/or appearance of each of the Holders is required by applicable Law), either at Law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this CVR Agreement or in aid of the exercise of any power granted in this CVR Agreement or to enforce any other legal or equitable right vested in the Trustee by this CVR Agreement or by Law.

SECTION 8.5 Restoration of Rights on Abandonment of Proceedings. In case the Trustee or any Holder shall have proceeded to enforce any right under this CVR Agreement and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then and in every such case the Company and the Trustee and the Holders shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Holders shall continue as though no such proceedings had been taken.

SECTION 8.6 Limitations on Suits by Holders. Subject to the right of the Acting Holders under Section 7.6 and the rights of the Holders under Section 8.7, no Holder of any Security shall have any right by virtue or by availing of any provision of this CVR Agreement to institute any action or proceeding at Law or in equity or in bankruptcy or otherwise upon or under or with respect to this CVR Agreement, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of breach and of the continuance thereof, as hereinbefore provided, and unless also the Acting Holders shall have made written request upon the Trustee to institute such action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for fifteen (15) days after its receipt of such notice and request shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 8.9; it being understood and intended, and being expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee, that no one or more Holders of Securities shall have any right in any manner whatever by virtue or by availing of any provision of this CVR Agreement to effect, disturb or prejudice the rights of any other such Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this CVR Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities. For the protection and enforcement of the provisions of this Section 8.6, each and every Holder and the Trustee shall be entitled to such relief as can be given either at Law or in equity.

SECTION 8.7 Unconditional Right of Holders to Institute Certain Suits. Notwithstanding any other provision in this CVR Agreement and any provision of any Security, the right

of any Holder of any Security to receive payment of the amounts payable in respect of such Security on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 8.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Breach.

(a) Except as provided in Section 8.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by Law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at Law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

(b) No delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Breach occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Breach or an acquiescence therein; and, subject to Section 8.6, every power and remedy given by this CVR Agreement or by Law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

SECTION 8.9 Control by Holders.

(a) The Holders of at least a majority of the Outstanding CVRs shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any power conferred on the Trustee with respect to the Securities by this CVR Agreement; provided that such direction shall not be otherwise than in accordance with Law and the provisions of this CVR Agreement; and provided further that (subject to the provisions of Section 4.1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee, or a committee of directors or Responsible Officers of the Trustee shall determine that the action or proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities not joining in the giving of said direction.

(b) Nothing in this CVR Agreement shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Holders.

SECTION 8.10 Waiver of Past Breaches.

(a) In the case of a breach or a Breach specified in clause (b), (c) or (d) of Section 8.1, the Holders of at least a majority of the Outstanding CVRs may waive any such Breach, and its consequences except a breach in respect of a covenant or provisions hereof which cannot be modified or amended without the consent of the Holder of each Security affected. In the case of

any such waiver, the Company, the Trustee and the Holders of the Securities shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other breach or impair any right consequent thereon.

(b) Upon any such waiver, such breach shall cease to exist and be deemed to have been cured and not to have occurred, and any Breach arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this CVR Agreement; but no such waiver shall extend to any subsequent or other Breach or other breach of any kind or impair any right consequent thereon.

SECTION 8.11 The Trustee to Give Notice of Breach, But May Withhold in Certain Circumstances. The Trustee shall transmit to the Holders, as the names and addresses of such Holders appear on the Security Register (as provided under Section 313(c) of the Trust Indenture Act, if applicable), notice by mail of all breaches which have occurred and are known to the Trustee, such notice to be transmitted within ninety (90) days after the occurrence thereof, unless such breaches shall have been cured before the giving of such notice (the term “breach” for the purposes of this Section 8.11 being hereby defined to mean any event or condition which is, or with notice or lapse of time or both would become, a Breach); provided that, except in the case of a failure to pay the amounts payable in respect of any of the Securities, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

SECTION 8.12 Right of Court to Require Filing of Undertaking to Pay Costs. All Parties to this CVR Agreement agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this CVR Agreement or in any suit against the Trustee for any action taken, suffered or omitted by it as the Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 8.12 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder or group of Holders holding in the aggregate more than ten percent (10%) of the Securities Outstanding or to any suit instituted by any Holder for the enforcement of the payment of any Security on or after the due date expressed in such Security.

ARTICLE 9

CONSOLIDATION, MERGER, SALE OR CONVEYANCE

SECTION 9.1 Company May Consolidate, etc., on Certain Terms. The Company covenants that it shall not merge (fusion) or consolidate with or into any other Person (other than a wholly-owned subsidiary of the Company), split-off (scission), or sell or convey all or substantially all of its assets to any Person (including in connection with a spin-off transaction (apport partiel d’actif)), unless (a) the Company shall be the continuing Person, or the successor Person or the Person which acquires by sale or conveyance all or substantially all the assets of

the Company (or, in the case of a split-off (scission) or spin-off (apport partiel d’actif), the Person who has received the largest portion of the assets relating to the Product) shall be a Person organized under the Laws of the United States of America or any State thereof or of France or of any other member of the European Union and shall expressly assume by an instrument supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the Securities, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this CVR Agreement to be performed or observed by the Company, including, without limitation, the provisions concerning governing law and consent to jurisdiction set forth in Section 1.10 hereof, (b) the Company, or such successor Person, as the case may be, shall not, immediately after such merger or consolidation, split-off, or such sale or conveyance, be in breach in the performance of any such covenant or condition and (c) in the case of a split-off or spin-off, (i) such successor Person shall have a corporate credit rating after the split-off or spin-off transaction from either ▇▇▇▇▇’▇ Investor Services, Inc. or Standard & Poor’s Ratings Service that is at least as high as “A-,” “A3” or their equivalent and (ii) the Company shall have certified to the Trustee that, to the Company’s knowledge based upon the reasons articulated in such certificate, such successor Person is capable of fulfilling all obligations to be assumed by it under the CVR Agreement, including the covenant set forth in Section 7.10.

SECTION 9.2 Successor Person Substituted.

(a) In case of any such consolidation, merger, split-off, spin-off, sale or conveyance, and following such an assumption by the successor Person, such successor Person shall succeed to and be substituted for the Company with the same effect as if it had been named herein. Such successor Person may cause to be signed, and may issue either in its own name or in the name of the Company prior to such succession any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation instead of the Company and subject to all the terms, conditions and limitations in this CVR Agreement prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered to the Trustee for authentication, and any Securities which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Securities so issued shall in all respects have the same legal rank and benefit under this CVR Agreement as the Securities theretofore or thereafter issued in accordance with the terms of this CVR Agreement as though all of such Securities had been issued at the date of the execution hereof.

(b) In case of any such consolidation, merger, sale or conveyance, such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. The successor entity to such consolidation, merger, sale or conveyance may satisfy the obligations of Section 5.4(a)(i) and (ii) of this CVR Agreement by providing copies of such successor entity’s Exchange Act Documents in the case of Section 5.4(a)(i) or such successor entity’s financial information in the case of Section 5.4(a)(ii).

(c) In the event of any such sale, transfer or conveyance (other than a conveyance by way of lease) the Company or any Person which shall theretofore have become such in the manner described in this Article 9 shall be discharged from all obligations and covenants under this CVR Agreement and the Securities and may be liquidated and dissolved.

SECTION 9.3 Opinion of Counsel to the Trustee. The Trustee, subject to the provisions of Sections 4.1 and 4.2, shall receive an Officer’s Certificate and Opinion of Counsel, prepared in accordance with Sections 1.2 and 1.3, as conclusive evidence that any such consolidation, merger, sale or conveyance, and any such assumption, and any such liquidation or dissolution, complies with the applicable provisions of this CVR Agreement, and if a supplemental agreement is required in connection with such transaction, such supplemental agreement complies with this Article 9 and that there has been compliance with all conditions precedent herein provided for or relating to such transaction.

SECTION 9.4 Successors. All covenants, provisions and agreements in this CVR Agreement by or for the benefit of the Company, the Trustee or the Holders shall bind and inure to the benefit of their respective successors, assigns, heirs and personal representatives, whether so expressed or not. The Company may assign this CVR Agreement without the prior written consent of the other Parties to this CVR Agreement to one or more of its direct or indirect Subsidiaries, provided, however, that in the event of any such assignment the Company shall remain subject to its obligations and covenants hereunder, including, but not limited to, its obligation to make any Product Sales Milestone Payments, the Approval Milestone Payment and the Production Milestone Payment.

ARTICLE 10

PURCHASE OF SECURITIES UPON CVR FAILURE EVENT

SECTION 10.1 Notice to Trustee. In the event that a Failure Purchase Eligibility Date has occurred and the Company elects to purchase the Securities pursuant to the provisions of Section 10.5 hereof (a “Failure Purchase”), it shall furnish to the Trustee, at least thirty (30) days (unless a shorter period shall be agreed to by the Trustee) but not more than sixty (60) days before the date on which the Company proposes to consummate the Failure Purchase (any such date, a “Failure Purchase Date”) (but in any event prior to the notice provided pursuant to Section 10.2 hereof), an Officer’s Certificate (a “Failure Purchase Offer”) setting forth (i) the clause of this CVR Agreement pursuant to which the Failure Purchase shall occur, (ii) the Failure Purchase Date, and (iii) the Failure Purchase Price, determined in accordance with Section 10.5 hereof.

SECTION 10.2 Notice of Failure Purchase. At least thirty (30) days but not more than sixty (60) days before a Failure Purchase Date, the Company shall mail or cause to be mailed, a notice of Failure Purchase to each Holder at its registered address (the “Failure Purchase Notice”) and shall publicly disclose the election of the Failure Purchase and the information required to be contained in the Failure Purchase Notice pursuant to this Section 10.2. The Failure Purchase Notice shall identify the number of Securities Outstanding and shall state:

(a) the Failure Purchase Date;

(b) the Failure Purchase Price;

(d) that Securities must be surrendered to the Paying Agent to collect the Failure Purchase Price;

(e) that, unless the Company fails to make payment of the Failure Purchase Price, all right, title and interest in and to the Securities and any CVR Payment or any other amounts due under this CVR Agreement, if any, on Securities called for Failure Purchase ceases to accrue on and after the Failure Purchase Date;

(f) the clause of this CVR Agreement pursuant to which the Failure Purchase shall occur; and

(g) that no representation is made as to the correctness or accuracy of the CUSIP and ISIN number, if any, listed in such notice or printed on the Securities.

At the Company’s request, the Trustee shall give the Failure Purchase Notice in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee at least forty five (45) days (unless a shorter period shall be agreed to by the Trustee) but not more than sixty (60) days prior to the Failure Purchase Date, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

SECTION 10.3 Effect of Failure Purchase Notice. Once the Failure Purchase Notice is mailed in accordance with Section 10.2 hereof, the Securities shall become irrevocably due and payable on the Failure Purchase Date at the Failure Purchase Price. A Failure Purchase Notice shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give a particular Holder his or her Failure Purchase Notice, or any defect in such notice, shall not affect the validity of the proceedings for the Failure Purchase.

SECTION 10.4 Deposit of Failure Purchase Price. On or one (1) Business Day prior to the Failure Purchase Date, the Company shall deposit with the Trustee or with the paying agent (if different from the Trustee) money sufficient to pay the Failure Purchase Price of all Securities Outstanding on that date. The Trustee or the paying agent shall promptly return to the Company any money deposited with the Trustee or the paying agent by the Company in excess of the amounts necessary to pay the Failure Purchase Price of all Securities Outstanding.

If the Company complies with the provisions of the preceding paragraph, on and after the Failure Purchase Date, all right, title and interest of a Holder to any CVR Payment, if any, shall cease to accrue on the Securities. If any Security called for Failure Purchase shall not be so paid upon surrender for Failure Purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid Failure Purchase Price from the Failure Purchase Date, until such Failure Purchase Price is paid at the Shortfall Interest Rate.

SECTION 10.5 Failure Purchase by the Company. The Company may, for a period of sixty (60) days after any Failure Purchase Eligibility Date, issue the Failure Purchase Notice in accordance with Section 10.2. Upon issuance of the Failure Purchase Notice and in compliance with the other provisions of this Article 10, the Company shall, on the Failure Purchase Date specified in such Failure Purchase Notice, purchase and cancel all (but not less than all) of the outstanding Securities at a cash price equal to the volume weighted average price paid per

Security for all Securities traded over the forty-five (45) trading days prior to the fifth (5th) trading day prior to the date of the Failure Purchase Notice (the “Failure Purchase Price”). If the Company has not issued the Failure Purchase Notice within such thirty (30) day period after the occurrence of a Failure Purchase Eligibility Date, it shall not be entitled to issue a Failure Purchase Notice and purchase and cancel the Securities until the next instance in which a Failure Purchase Eligibility Date occurs.

IN WITNESS WHEREOF, the Parties hereto have caused this CVR Agreement to be duly executed, all as of the day and year first above written.

[Form of Reverse of CVR Certificate]

1.

The CVR Agreement is hereby incorporated herein by reference and made a part hereof. Reference is hereby made to the CVR Agreement for a full statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the CVRs.

3. Subject to the terms and conditions of the CVR Agreement, on any Product Sales Milestone Payment Date, the Company shall pay to the Trustee, for the benefit of the Holder hereof as of the applicable record date, for each CVR represented hereby, the Product Sales Milestone Payment with respect to such Product Sales Milestone Payment Date.

7. If a Breach occurs and is continuing, either the Trustee may or the Acting Holders, by notice to the Company and to the Trustee shall bring suit in accordance with the terms and conditions of the CVR Agreement to protect the rights of the Holders, including to obtain payment of all amounts then due and payable, with interest at the Breach Interest Rate from the date of the Breach through the date payment is made or duly provided for.

8. No reference herein to the CVR Agreement and no provision of this CVR Certificate or of the CVR Agreement shall alter or impair the obligation of the Company, which

is absolute and unconditional, to pay any amounts determined pursuant to the terms hereof and of the CVR Agreement at the times, place and amount, and in the manner, herein prescribed.

9. As provided in the CVR Agreement and subject to certain limitations therein set forth, the transfer of the CVRs represented by this CVR Certificate is registrable on the Security Register, upon surrender of this CVR Certificate for registration of transfer at the office or agency of the Company maintained for such purpose in the Borough of Manhattan, The City of New York, accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new CVR Certificates, for the same amount of CVRs, shall be issued to the designated transferee or transferees. The Company hereby initially designates the office of [TRUSTEE] at [•] as the office for registration of transfer of this CVR Certificate.

10. As provided in the CVR Agreement and subject to certain limitations therein set forth, this CVR Certificate is exchangeable for one or more CVR Certificates representing the same number of CVRs as represented by this CVR Certificate as requested by the Holder surrendering the same.

11. No service charge shall be made for any registration of transfer or exchange of CVRs, but the Company may require payment of a sum sufficient to cover any documentary, stamp or similar tax or other similar governmental charge payable in connection with any registration of transfer or exchange of Securities, other than (i) exchanges pursuant to Sections 3.4, 3.6 or 6.6 of the CVR Agreement not involving any transfer or (ii) transfers pursuant to Article 10 of the CVR Agreement.

12. Prior to the time of due presentment of this CVR Certificate for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this CVR Certificate is registered as the owner hereof for all purposes, and neither the Company, the Trustee nor any agent shall be affected by notice to the contrary.

13. Neither the Company nor the Trustee has any duty or obligation to the Holder of this CVR Certificate, except as expressly set forth herein or in the CVR Agreement.

14. As provided in the CVR Agreement and subject to certain limitations therein set forth, the rights of the Holder of this CVR Certificate shall terminate on the Termination Date.

15. Purchase of Securities Upon CVR Failure Event.

a. Notice to Trustee. In the event a Failure Purchase Eligibility Date has occurred and the Company elects to purchase the Securities pursuant to the provisions of Section 10.5 of the CVR Agreement (a “Failure Purchase”), it shall furnish to the Trustee, at least thirty (30) days (unless a shorter period shall be agreed to by the Trustee) but not more than sixty (60) days before the date on which the Company proposes to consummate the Failure Purchase (any such date, the “Failure Purchase Date”) (but in any event prior to the notice provided pursuant to Section 10.2 of the CVR Agreement), an Officer’s Certificate (a “Failure Purchase Offer”) setting forth (i) the clause of the CVR Agreement pursuant to which the Failure Purchase shall occur, (ii) the Failure Purchase Date, and (iii) the Failure Purchase Price, determined in accordance with Section 10.5 of the CVR Agreement.

b. Notice of Failure Purchase. At least thirty (30) days but not more than sixty (60) days before a Failure Purchase Date, the Company shall mail or cause to be mailed, by first class mail, a notice of Failure Purchase to each Holder at its registered address(the “Failure Purchase Notice”) and shall publicly disclose the election of the Failure Purchase and the information required to be contained in the Failure Purchase Notice pursuant to Section 10.2 of the CVR Agreement. The notice (the “Failure Purchase Notice”) shall identify the number of Securities Outstanding and shall state:

(i)

the Failure Purchase Date;

(ii)

the Failure Purchase Price;

(iii)

the name and address of the paying agent;

(iv)

that Securities must be surrendered to the Paying Agent to collect the Failure Purchase Price;

(v)

that, unless the Company fails to make payment on the Failure Purchase Price, all right, title and interest in and to the Securities and any CVR Payment or any other amounts due under the CVR Agreement, if any, on Securities called for Failure Purchase ceases to accrue on and after the Failure Purchase Date;

(vi)

the clause of the CVR Agreement pursuant to which the Failure Purchase shall occur; and

(vii)

that no representation is made as to the correctness or accuracy of the CUSIP and ISIN number, if any, listed in such notice or printed on the Securities.

c. Effect of Failure Purchase Notice. Once the Failure Purchase Notice is mailed in accordance with Section 10.2 of the CVR Agreement, the Securities shall become irrevocably due and payable on the Failure Purchase Date at the Failure Purchase Price. A Failure Purchase Notice shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give a particular Holder his or her Failure Purchase Notice, or any defect in such Failure Purchase Notice, shall not affect the validity of the proceedings for the Failure Purchase.

d. Deposit of Failure Purchase Price. On or one (1) Business Day prior to the Failure Purchase Date, the Company shall deposit with the Trustee or with the paying agent (if different from the Trustee) money sufficient to pay the Failure Purchase Price of all Securities

Outstanding on that date. The Trustee or the paying agent shall promptly return to the Company any money deposited with the Trustee or the paying agent by the Company in excess of the amounts necessary to pay the Failure Purchase Price of all Securities Outstanding.

If the Company complies with the provisions of the preceding paragraph, on and after the Failure Purchase Date, all right, title and interest of a Holder to any CVR Payment, if any, shall cease to accrue on the Securities called for. If any Security called for Failure Purchase shall not be so paid upon surrender for Failure Purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid Failure Purchase Price from the Failure Purchase Date until such Failure Purchase Price is paid at the Shortfall Interest Rate.

e. Failure Purchase by the Company. The Company may, for a period of sixty (60) days after any Failure Purchase Eligibility Date, issue the Failure Purchase Notice in accordance with Section 10.2 of the CVR Agreement. Upon issuance of the Failure Purchase Notice and in compliance with the other provisions of Article 10 of the CVR Agreement, the Company shall, on the Failure Purchase Date specified in such Failure Purchase Notice, purchase and cancel all (but not less than all) of the outstanding Securities at a cash price equal to the volume weighted average price paid per Security for all Securities traded over the forty-five (45) trading days prior to the fifth (5th) trading day prior to the date of the Failure Purchase Notice (the “Failure Purchase Price”). If the Company has not issued the Failure Purchase Notice within such thirty (30) day period after the occurrence of a Failure Purchase Eligibility Date, it shall not be entitled to issue a Failure Purchase Notice and purchase and cancel the Securities until the next instance in which a Failure Purchase Eligibility Date occurs.
