AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) dated as of October 24, 2011 is among CUBIST PHARMACEUTICALS, INC. (“Parent”), a Delaware corporation, FRD ACQUISITION CORPORATION (“Sub”), a newly-formed Delaware corporation and a direct or indirect wholly-owned subsidiary of Parent, and ADOLOR CORPORATION (the “Company”), a Delaware corporation.

R E C I T A L S

WHEREAS, Parent and the Board of Directors of each of Sub and the Company has approved the acquisition of the Company by Parent on the terms and conditions set forth in this Agreement;

WHEREAS, in furtherance thereof, it is proposed that Sub commence a tender offer (as it may be amended from time to time as permitted by this Agreement, the “Offer”) to acquire all shares of the issued and outstanding common stock, par value $0.0001 per share, of the Company (the “Shares”), for (a) $4.25 for each Share, net to the seller in cash (the “Closing Amount”), without interest, plus (b) one contingent payment right for each Share (a “CPR”), which shall represent the right to receive the Payment Amounts (as such term is used in the Contingent Payment Rights Agreement in the form attached hereto as Annex IV (the “CPR Agreement”) to be entered into between Parent and Computershare Inc., a Delaware corporation and its fully owned subsidiary Computershare Trust Company, N.A., a national banking association (the “Rights Agent”)), if any, at the times provided for in the CPR Agreement, without interest; the Closing Amount plus one CPR, collectively, or any such higher consideration per Share as may be paid in the Offer, referred to herein as the “Offer Price”;

WHEREAS, the Board of Directors of each of Sub and the Company has approved this Agreement and the transactions contemplated hereby, including the Merger following the Offer, in accordance with the Delaware General Corporation Law (“DGCL”) and upon the terms and subject to the conditions set forth herein;

WHEREAS, the Board of Directors of the Company (the “Company Board of Directors”) has determined that the consideration to be paid for each Share in the Offer and the Merger is fair to the holders of such Shares and has resolved to recommend that the holders of Shares accept the Offer and adopt this Agreement upon the terms and subject to the conditions set forth herein;

WHEREAS, concurrently with the execution and delivery of this Agreement, and as a condition and inducement to Parent entering into this Agreement, certain Company stockholders (the “Principal Stockholders”) have entered into tender and voting agreements, dated as of the date hereof, in substantially the form set forth in Annex II, pursuant to which, among other things, the Principal Stockholders have agreed to tender Shares to Sub in the Offer (the “Tender and Voting Agreement”); and

WHEREAS, the Company, Parent and Sub desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger.

NOW, THEREFORE, in consideration of the foregoing and the respective covenants, agreements, representations and warranties set forth herein, the parties agree as follows:

SECTION 1 - THE OFFER AND THE MERGER

1.1. The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Section 8.1, Parent shall cause Sub to, and Sub shall commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”)) the Offer as promptly as practicable and in any event no later than the tenth (10th) business day following the date hereof. The obligations of Sub to accept for payment and to pay for any Shares validly tendered and not withdrawn prior to the expiration of the Offer (as it may be extended in accordance with this Section 1.1(a) ) shall be subject only to the conditions set forth in Annex I (collectively, the “Offer Conditions” and each an “Offer Condition”). Subject to the prior satisfaction or, to the extent permitted, waiver by Parent and Sub of the Offer Conditions, Parent shall cause Sub to, and Sub shall, consummate the Offer in accordance with its terms and accept for payment and pay the Offer Price for all Shares tendered and not withdrawn promptly following the acceptance in compliance with Rule 14e-1(c) under the Exchange Act of Shares for payment pursuant to the Offer. The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that contains the terms set forth in this Agreement and the Offer Conditions. Parent and Sub expressly reserve the right to waive any Offer Conditions, to increase the Offer Price and to make any other changes in the terms of the Offer; provided, however, that Sub shall not, and Parent shall cause Sub not to, decrease the Closing Amount or CPR Payment Amount, change the form of payment of the Closing Amount or CPR Payment Amount, decrease the number of Shares sought in the Offer, waive or change the Minimum Condition, impose additional conditions to the Offer, amend any of the Offer Conditions so as to broaden the scope of any such condition, extend the offer beyond a date that is twenty-one (21) business days after commencement of the Offer or the last extension in accordance with this Section 1.1, if any, of the Offer, whichever is later (the “Expiration Date”) except as set forth below, or otherwise amend any other term or condition of the Offer in a manner materially adverse to the holders of Shares, in each case without the prior written consent of the Company. Notwithstanding the foregoing and subject to the parties respective termination rights set forth in Section 8.1, Sub may, without the consent of the Company (i) extend the Offer beyond the initial expiration date if, at any scheduled (or extended) expiration of the Offer, any of the conditions to Sub’s obligation to accept Shares for payment, shall not be satisfied or waived, (ii) extend the Offer for any period required by any rule, regulation or interpretation of the United States Securities and Exchange Commission (“SEC”) or its staff applicable to the Offer. In addition to the foregoing, Sub also may provide a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act if, as of the Expiration Date, all of the conditions to Sub’s obligations to accept for payment and pay for all Shares are satisfied or waived, but there shall not have been validly tendered and not withdrawn pursuant to the Offer that number of Shares necessary to permit the Merger to be effected without a meeting of the Company’s stockholders in accordance with the DGCL.

(b) Subject to the parties’ respective termination rights set forth in Section 8.1, if, at the time at which the Offer is scheduled to expire, any Offer Condition has not been satisfied or has not been validly waived, then, if so requested by the Company by written notice on or prior to the date the Offer is then scheduled to expire, Sub shall extend the Offer for up to one period of not more than five (5) business days per extension period, until all of the Offer Conditions have been satisfied or, to the extent permitted, validly waived; provided, however, that the Company shall not have the right to request an extension pursuant to this Section 1.1(b) if, at the time of any proposed extension, an Acquisition Proposal has been publicly made and the Company Board of Directors failed to reaffirm its recommendation of the Offer within two (2) business days of Parent’s request.

(c) On the date of commencement of the Offer, Parent and Sub shall file with the SEC, pursuant to Regulation M-A under the Exchange Act (“Regulation M-A”), a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits thereto, the “Schedule TO”). The Schedule TO shall include, as exhibits, the Offer to Purchase and a form of letter of transmittal and summary advertisement (collectively, together with any amendments and supplements thereto, the “Offer Documents”). Subject to Section 5.2, the Company hereby consents to the inclusion in the Offer Documents of the recommendation and the approval of the Company Board of Directors referred to in Section 3.20(a). Subject to the Company’s compliance with Section 1.2(c), Parent and Sub agree to take all steps necessary to cause the Offer Documents to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable Law. Parent and Sub, on the one hand, and the Company, on the other hand, agree to promptly correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by Law. Parent and Sub 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 Law. The Company shall be given a reasonable opportunity to review and comment on the Schedule TO and any amendment thereto before it is filed with the SEC, and Parent and Sub shall give due consideration to all reasonable and appropriate additions, deletions or changes thereto suggested by the Company and its legal counsel. In addition, Parent and Sub agree to provide the Company with any comments, whether written or oral, that Parent, Sub or their counsel may receive from time to time prior to the expiration or termination of the Offer, from the SEC or its staff with respect to the Offer Documents, promptly after receipt of such comments, and any written or oral responses thereto, and the Company shall be given a reasonable opportunity to review such comments and have the right to consult with Parent, Sub and their counsel prior to responding to any such comments, either in written or oral form, and Parent and Sub shall give due consideration to the reasonable and appropriate views and comments of the Company and its legal counsel related thereto.

(d) Parent shall provide or cause to be provided to Sub promptly following the expiration of the Offer or any subsequent extension thereof, as applicable, all funds necessary to pay the aggregate Closing Amounts with respect to Shares that have been validly tendered and not withdrawn pursuant to the Offer and that Sub is obligated to accept for payment pursuant to the Offer and permitted to accept for payment under applicable Law.

(e) Parent shall, at or prior to the Acceptance Time (as defined in Section 5.2(b)), duly authorize, execute and deliver the CPR Agreement.

1.2. Company Actions.

(a) Subject to Section 5.2 and to any consents or approvals of the Company’s stockholders required under applicable Law, the Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated hereby.

(b) On the date the Offer is commenced, the Company shall, in a manner that complies with Rule 14d-9 under the Exchange Act, file with the SEC a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments, supplements and exhibits thereto, the “Schedule 14D-9”) which shall, subject to the provisions of Section 5.2, contain the recommendation of the Company Board of Directors referred to in Section 3.20(a) and all information required by Delaware Law. The Company further agrees to take all steps necessary to cause the Schedule 14D-9 to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable Law. The Company shall provide to Parent a copy of the Company financial advisor’s fairness opinion and a summary of the analysis underlying such fairness opinion to be included in the Schedule 14D-9. The Company, on the one hand, and Parent and Sub, on the other hand, agree to promptly correct and supplement any information provided by it for use in the Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by Law. The Company 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 the Shares, in each case as and to the extent required by applicable Law. Parent and Sub shall be given the opportunity to review and comment on the Schedule 14D-9 and any amendment thereto before filing with the SEC and the Company and its counsel shall give due consideration to all reasonable and appropriate additions, deletions or changes thereto suggested by Parent and its counsel. In addition, the Company agrees to provide Parent and Sub any comments, whether written or oral, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments, and to consult with Parent, Sub and their counsel and give due consideration to all reasonable and appropriate additions, deletions or changes thereto suggest by Parent and its counsel prior to responding to any such comments, either in written or oral form.

(c) The Company shall promptly furnish or cause to be furnished to Parent or Sub mailing labels, security position listings and all available listings and computer files containing the names and addresses of the record holders of the Shares as of a recent date, and of those persons becoming record holders subsequent to such date, and shall promptly furnish Parent or Sub with such information and assistance (including, but not limited to, lists of holders of the Shares, updated periodically, and their addresses, mailing labels and lists of security positions) as Parent or Sub or its agent(s) may reasonably request. Subject to applicable Law, such information shall be held confidential by Parent and Sub under the terms of the Mutual Confidentiality and Non-Use Agreement, dated July 26, 2011, entered into between Parent and the Company (as amended, the “Confidentiality Agreement”). For the avoidance of doubt, the parties agree that the Confidentiality Agreement does not restrict steps to prepare, file or

disseminate the Offer Documents and any other documents necessary to consummate the transactions contemplated hereby.

1.3. The Merger.

(a) Subject to the terms and conditions of this Agreement, at the Effective Time, the Company and Sub shall consummate a merger (the “Merger”) in accordance with the DGCL pursuant to which (i) Sub will be merged with and into the Company and the separate corporate existence of Sub will thereupon cease; (ii) the Company will be the successor or surviving corporation in the Merger and will continue to be governed by the Laws of the State of Delaware; (iii) the corporate existence of the Company with all its rights, privileges, powers and franchises will continue; and (iv) the Company will succeed to and assume all the rights and obligations of Sub. The corporation surviving the Merger is sometimes hereinafter referred to as the “Surviving Corporation.” The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of the Company and Sub shall be vested in the Surviving Corporation, and all debts, liabilities and duties of the Company and Sub shall become the debts, liabilities and duties of the Surviving Corporation.

(b) At the Effective Time, the certificate of incorporation of the Company shall, by virtue of the Merger, be amended and restated in its entirety to be in the form of Annex III and, as so amended, shall be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

(c) At the Effective Time, and without any further action on the part of the Company or Sub, the bylaws of the Company shall be amended and restated in their entirety to be identical to the bylaws of Sub as in effect immediately prior to the Effective Time (except that such bylaws shall be amended to reflect that the name of the Surviving Corporation shall be Adolor Corporation), and, as so amended, shall be the bylaws of the Surviving Corporation until thereafter changed or amended as provided by the DGCL, the certificate of incorporation of the Surviving Corporation and such bylaws.

1.4. Effective Time. Parent, Sub and the Company shall cause a certificate of merger complying with Section 251 of the DGCL or a certificate of ownership and merger complying with Section 253 of the DGCL, as applicable (either the “Certificate of Merger”) to be executed and filed on the Closing Date (or on such other date as Parent and the Company may agree) with the Secretary of State of the State of Delaware as provided in the DGCL. The Merger shall become effective on the time and date on which the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or such later time and date as is specified in the Certificate of Merger (provided, however, that such later time and date shall not be more than five (5) business days after the filing without the written consent of the Company), such time hereinafter referred to as the “Effective Time.”

1.5. Closing. The closing of the Merger (the “Closing”) will take place at 9:00 a.m. (Boston time) on a date to be specified by the parties, such date to be no later than the second (2nd) business day after satisfaction or waiver of all of the conditions set forth in SECTION 7 capable of satisfaction prior to the Closing (the “Closing Date”), at the offices of

Ropes & Xxxx LLP, Prudential Tower, 000 Xxxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000, unless another date or place is agreed to in writing by the parties hereto.

1.6. Directors and Officers of the Surviving Corporation. The directors of Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation, and the officers of Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the officers of the Surviving Corporation, in each case until their respective successors shall have been duly elected, designated or qualified, or until their earlier death, resignation or removal in accordance with the Surviving Corporation’s certificate of incorporation and bylaws. Prior to the Effective Time, the Company shall cause each member of the Company Board of Directors, other than Parent’s or Sub’s designees pursuant to Section 6.8, to execute and deliver a letter effectuating his or her resignation as a director of the Company upon the Effective Time.

1.7. Subsequent Actions. If at any time after the Effective Time the Surviving Corporation shall determine, in its sole discretion, or shall be advised, that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either the Company or Sub acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of either the Company or Sub, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of each such corporation or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

1.8. Stockholders’ Meeting.

(a) If required by applicable Law in order to consummate the Merger, the Company, acting through the Company Board of Directors, in accordance with applicable Law and the Company’s certificate of incorporation and bylaws, shall:

(i) duly call, give notice of, convene and hold a special meeting of its stockholders to consider the adoption of this Agreement (the “Special Meeting”) as soon as reasonably practicable following the Acceptance Time;

(ii) as soon as reasonably practicable following the Acceptance Time, prepare and file with the SEC under the Exchange Act a preliminary proxy or information statement relating to the Merger and this Agreement and use its reasonable best efforts to obtain and furnish the information required to be included by the SEC in the Proxy Statement and, after Parent shall have had a reasonable opportunity to review and comment on the Proxy Statement, respond promptly to any comments made by the SEC with respect to the preliminary proxy or information statement and cause a definitive proxy or information statement (in either case, the “Proxy Statement”) to be mailed to its stockholders as promptly as practicable;

(iii) subject to Section 5.2, include in the Proxy Statement the recommendation of the Company Board of Directors that the stockholders of the Company vote in favor of the adoption of this Agreement; and

(iv) use commercially reasonable efforts to solicit from holders of Shares proxies in favor of the adoption of this Agreement and take all other action reasonably necessary or advisable to secure the approval of stockholders required by the DGCL and any other applicable Law and the Company’s certificate of incorporation and bylaws to effect the Merger.

(b) Parent agrees to vote, or cause to be voted, all of the Shares then beneficially owned by Sub in favor of the adoption of this Agreement and the approval of the Merger.

1.9. Merger Without Meeting of Stockholders. Notwithstanding Section 1.8, in the event that Sub has acquired at least ninety percent (90%) of the outstanding shares of each class of capital stock of the Company entitled to vote on the Merger, pursuant to the Offer or otherwise, the parties hereto agree, at the request of Parent and subject to SECTION 7, to take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after such acquisition, without a meeting of stockholders of the Company, in accordance with and subject to the DGCL.

1.10. Top-Up Option.

(a) The Company hereby grants to Sub an irrevocable option (the “Top-Up Option”), exercisable only on the terms and conditions set forth in this Section 1.10, to purchase at a price per share equal to the greater of (i) the last reported sale price of a Share on The Nasdaq Stock Market on the last trading day prior to the date on which the Top-Up Option is exercised or (ii) the Closing Amount, newly issued Shares (the “Top-Up Shares”) so that, when added to the number of Shares owned by Sub prior to the exercise of the Top-Up Option, Sub will own at least ninety percent (90%) of the Shares outstanding immediately after the issuance of the Top-Up Shares (not including in the Shares owned by Sub any Shares tendered pursuant to unfulfilled guaranteed delivery procedures); provided, however, that (i) the Top-Up Option shall not be exercisable for a number of Shares in excess of the Shares authorized and unissued at the time of exercise of the Top-Up Option and (ii) the Top-Up Option may not be exercised unless, following the Acceptance Time or after a subsequent offering period, seventy percent (70%) or more of the Shares shall be owned by Sub. The Top-Up Option shall be exercisable once at any time following the Acceptance Time and prior to the earlier to occur of (A) the Effective Time and (B) the termination of this Agreement in accordance with its terms. Sub may assign the Top-Up Option and its rights and obligations pursuant to this Section 1.10, in its sole discretion, to Parent.

(b) The parties shall cooperate to ensure that the issuance and delivery of the Top-Up Shares complies with all applicable Laws, including compliance with an applicable exemption from registration under the Securities Act. If Sub wishes to exercise the Top-Up Option, Sub shall give the Company written notice, specifying (i) the number of Shares owned by Sub, (ii) a place and a time for the closing of such purchase and (iii) the manner in which Sub

intends to pay the applicable purchase price. The Company shall, as soon as practicable following receipt of such notice, deliver written notice to Sub specifying, based on the information provided by Sub in its notice, the number of Top-Up Shares. Prior to the closing of the purchase of the Top-Up Shares, upon Sub’s request, the Company shall use its reasonable best efforts to cause its transfer agent to certify in writing to Sub the number of Shares issued and outstanding (A) as of immediately prior to the exercise of the Top-Up Option and (B) after giving effect to the issuance of the Top-Up Shares.

(c) The aggregate purchase price payable for the Top-Up Shares may be paid, at Sub’s option, (i) in cash, (ii) 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 (iii) a combination thereof, provided that Sub shall use cash for at least the aggregate par value of the Top-Up Shares. The Company Board has approved such consideration for the Top-Up Shares. Any such promissory note shall include the following terms: (1) the maturity date shall be one (1) year after issuance, (2) the unpaid principal amount of the promissory note shall accrue simple interest at a per annum rate of 3.00% and (3) the promissory note may be prepaid in whole or in part at any time, without penalty or prior notice.

(d) Parent and Sub acknowledge that the Shares that Sub may acquire upon exercise of the Top-Up Option shall not be registered under the Securities Act and shall be issued in reliance upon an exemption for transactions not involving a public offering. Sub agrees that the Top-Up Option, and the Top-Up Shares to be acquired upon exercise of the Top-Up Option, if any, are being and shall be acquired by Sub 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).

(e) The obligation of the Company to deliver Top-Up Shares upon the exercise of the Top-Up Option is subject to the conditions that (i) no provision of any applicable Law and no judgment, injunction, order or decree shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Shares in respect of such exercise, (ii) due to the exercise of the Top-Up Option, the number of Shares owned by Parent, Sub and their Affiliates will constitute more than ninety percent (90%) of the number of Shares that will be outstanding on a fully-diluted basis immediately after the issuance of the Top-Up Shares, and (iii) Sub has accepted for payment all Shares validly tendered in the Offer and not withdrawn.

SECTION 2 - CONVERSION OF SECURITIES

2.1. Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders of any Shares or any shares of common stock, par value $0.01 per share, of Sub (“Sub Common Stock”):

(a) Sub Common Stock. Each issued and outstanding share of Sub Common Stock shall be converted into and become one (1) fully paid and nonassessable share of common stock of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are owned by the Company as treasury stock and any Shares owned by Parent or Sub shall

automatically be cancelled and retired and shall cease to exist, and no consideration shall be payable in exchange therefor.

(c) Conversion of Shares. Subject to Section 2.4, each issued and outstanding Share (other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares) shall be converted into the right to receive the (i) the Closing Amount, payable to the holder thereof in cash, without interest, plus (ii) one CPR, or any such higher consideration as may be paid in the Offer (the “Merger Consideration”). From and after the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate (a “Certificate”) or book-entry share (a “Book-Entry Share”) representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor, without interest thereon, upon the surrender of such Certificate or Book-Entry Share in accordance with Section 2.2.

2.2. Exchange of Certificates.

(a) Paying Agent. Parent shall designate StockTrans, Inc. or another bank or trust company that is reasonably acceptable to the Company to act as agent for the holders of Shares in connection with the Merger (the “Paying Agent”) and to receive the aggregate Closing Amounts to which holders of Shares shall become entitled pursuant to Section 2.1(c). Parent shall cause the Surviving Corporation to provide to the Paying Agent on a timely basis, promptly (in any event no later than the immediately following business day) after the Effective Time, and as and when needed after the Effective Time, cash necessary to pay the aggregate Closing Amounts for the Shares converted in the Merger into the right to receive the Merger Consideration (such cash being hereinafter referred to as the “Exchange Fund”). If for any reason the Exchange Fund is inadequate to pay the aggregate Closing Amounts to which holders of Shares shall be entitled under Section 2.1(c), Parent shall promptly deposit or cause the Surviving Corporation promptly to deposit additional cash with the Paying Agent sufficient to make all payments of aggregate Closing Amounts, and Parent and the Surviving Corporation shall in any event be liable for payment thereof. The Paying Agent may invest the cash in the Exchange Fund as directed by Parent; provided, however, that such investments, if any, shall be in obligations of or guaranteed by the United States or any agency or instrumentality thereof and backed by the full faith and credit of the United States, in commercial paper obligations rated P-1 or A-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in money market funds that invest only in such United States government and commercial paper obligations. Any interest and other income resulting from such investments shall be paid to Parent. No investment of the Exchange Fund shall relieve Parent, Surviving Corporation or the Paying Agent from promptly making the payments required under this Article II, and following any losses from any such investment, Parent shall promptly provide any additional cash funds to the Paying Agent for the benefit of the Company’s shareholders at the Effective Time in the amount of such losses, which additional funds will be deemed to be part of the Exchange Fund.

(b) Exchange Procedures. Promptly after the Effective Time, the Paying Agent shall mail to each holder of record of a Certificate or a Book-Entry Share, which immediately prior to the Effective Time represented outstanding Shares, whose shares were

converted pursuant to Section 2.1(c) into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificate or Book-Entry Shares shall pass, only upon delivery of the Certificates (or affidavits of loss for such Certificates) or Book-Entry Shares to the Paying Agent and shall be in such form and have such other provisions as Parent and the Company mutually agree prior to the Effective Time); 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 Share 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 and such other documents as may be reasonably requested by the Paying Agent, the holder of such Certificate or Book-Entry Share shall 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 2.2, each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 2.2, without interest thereon, and shall not evidence any interest in, or any right to exercise the rights of a stockholder or other equity holder of, the Company or the Surviving Corporation.

(c) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of Certificates or Book-Entry Shares evidencing ownership of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this SECTION 2.

(d) Termination of Exchange Fund; No Liability. At any time following six (6) months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to the Paying Agent’s routine administrative procedures) to holders of Certificates and Book-Entry Shares, and thereafter such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates or Book-Entry Shares, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Certificate or Book-Entry Share for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If Certificates or Book-Entry Shares are not surrendered prior to the time such Certificates or Book-Entry shares would otherwise escheat to, or become Property of, any Governmental Entity, unclaimed Merger Consideration payable with respect to such Shares shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(e) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such amount as Parent may reasonably direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto.

2.3. Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has complied with Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into a right to receive the Merger Consideration, unless such holder fails to perfect or withdraws or otherwise loses his, her or its right to appraisal. From and after the Effective Time, a stockholder who has properly exercised such appraisal rights shall not have any rights of a stockholder of the Company or the Surviving Corporation with respect to such Shares, except those provided under Section 262 of the DGCL. A holder of Dissenting Shares shall be entitled to receive payment of the appraised value of such Shares held by him, her or it in accordance with Section 262 of the DGCL, unless, after the Effective Time, such holder fails to perfect or withdraws or loses his, her or its right to appraisal, in which case such Shares shall be converted into and represent only the right to receive the Merger Consideration, without interest thereon, upon surrender of the Certificates or Book-Entry Shares, pursuant to Section 2.2. 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 shall be determined in accordance with Section 262 of the DGCL without regard to the Top-Up Option, the Top-Up Shares or any promissory note delivered by Sub or Parent to the Company in payment for the Top-Up Shares.

(b) The Company shall give Parent (i) prompt written notice of any written demands for appraisal (including copies of such demands), attempted withdrawals of such demands and any other instruments received by the Company relating to rights of appraisal; and (ii) the opportunity to participate in the conduct of all negotiations and proceedings with respect to demands for appraisal. Except with the prior written consent of Parent, the Company shall not voluntarily make any payment with respect to any demands for appraisal or settle or offer to settle any such demands for appraisal.

2.4. Company Incentive Plans.

(a) At the Acceptance Time, each stock option (each a “Company Option” and, collectively, the “Company Options”) that was granted under the Company’s Amended and Restated 1994 Equity Compensation Plan or its 2011 Stock-Based Incentive Compensation Plan (formerly known as the 2003 Amended and Restated Stock-Based Incentive Compensation Plan) (the “Company Stock Plans”) and that is outstanding immediately prior to the Acceptance Time shall vest in full to the extent not already vested. The Company shall have provided to each holder of a Company Option, prior to the Effective Time, written notice and an opportunity to exercise such Company Option prior to the Effective Time. Between the Acceptance Time and

the Effective Time, Company Options that have an exercise price of less than $4.25 per share may be exercised, with such exercise effective immediately prior to the Effective Time, by assignment to the Surviving Corporation of a sufficient portion of the Closing Amount payable in the Merger with respect to the shares subject to such Company Options, provided that the holder of such Company Options irrevocably undertakes to exchange such shares pursuant to Section 2.2(b) hereof and instructs the Paying Agent to deduct the applicable portion of the Closing Amount that would otherwise be payable with respect to such shares. At the Effective Time, each then-outstanding Company Option shall be canceled and shall immediately cease to be outstanding, without any payment in respect of such Company Option or cancellation thereof except as provided in the following sentence. In full satisfaction of the cancellation of any Company Option described in the immediately preceding sentence that had a per-Share exercise price less than the last reported sale price of a Share on The Nasdaq Stock Market on the last trading day prior to the Acceptance Time, Parent shall, or shall cause the Surviving Corporation to, following the Effective Time, pay to the holder of such Company Option, (x) an amount in cash in respect thereof equal to the product of (I) the excess, if any, of the last reported sale price of a Share on The Nasdaq Stock Market on the last trading day prior to the Acceptance Time over the per-Share exercise price of such Company Option and (II) the number of Shares subject thereto (such payments to be net of applicable Taxes withheld pursuant to Section 2.6). As of the Effective Time, no Person shall retain any rights with respect to any previously outstanding Company Options except for the rights of a holder to receive any payment expressly contemplated by this Section 2.4(a).

(b) At the Acceptance Time, each share of restricted stock that was granted by the Company under a Company Stock Plan (each, a “Company Restricted Share” and, collectively, the “Company Restricted Stock”) that is unvested and outstanding immediately prior to the Acceptance Time shall vest and, after satisfaction of all applicable Tax and other withholding requirements pursuant to Section 2.6, be converted into the right to receive, as promptly as practicable following the Effective Time, the Merger Consideration.

(c) At the Acceptance Time, each performance-based deferred stock unit (each, a “Performance-Based DSU” and, collectively, the “Performance-Based DSUs”) and each time-vested deferred stock unit (each, a “Time-Vested DSU” and, collectively, the “Time-Vested DSUs”) (the Performance-Based DSUs and the Time-Vested DSUs being collectively referred to herein as the “DSUs”) that was granted by the Company under a Company Stock Plan that is unvested and outstanding immediately prior to the Acceptance Time shall vest and shall be satisfied by delivery of an equivalent number of Shares, less such number of Shares as shall be withheld pursuant to Section 2.6 to satisfy applicable Tax and other withholding requirements, such remaining Shares to be converted into the right to receive, as promptly as practicable following the Effective Time, the Merger Consideration.

(d) Any amounts to be paid pursuant to this Section 2.4 shall be in lieu of any amounts that would otherwise be payable pursuant to Section 2.1(c) in respect of Shares subject to Company Options, Company Restricted Shares and DSUs, as applicable.

(e) As of the Effective Time, the Company Stock Plans shall terminate and all rights under any provision of any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Company

Subsidiary shall be cancelled. The Company shall take, or cause to be taken, all actions necessary to effectuate the foregoing provisions of this Section 2.4, including, but not limited to, sending out the requisite notices, obtaining any necessary resolutions of the Board or a committee thereof, and obtaining all consents necessary to cash out and cancel all Company Options, Company Restricted Stock, and DSUs, so as to ensure that, after the Effective Time, no person shall have any rights under the Company Stock Plans except for the right to receive the payments, if any, contemplated by Section 2.4(a), 2.4(b) or 2.4(c).

2.5. Section 16. The Company Board of Directors shall, 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 (and related derivative securities) resulting from the transactions contemplated by this Agreement.

2.6. Withholding. Each of Parent, Sub and Surviving Corporation shall be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from any cash consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Shares, Company Options, Company Restricted Stock or DSUs, in each case directly or through an authorized agent with respect to any consideration payable or otherwise deliverable pursuant to this Agreement, such amounts as are required to be deducted or withheld under the Internal Revenue Code of 1986, as amended (the “Code”) or any provision of any other applicable federal, state, local or non-U.S. Tax Law from any such consideration, as reasonably determined by Parent. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid. Notwithstanding the foregoing and for the avoidance of doubt, (i) the Company shall (a) prior to the Acceptance Time, make arrangements consistent with the requirements of applicable law with each holder of Company Restricted Stock for the prompt satisfaction (through the withholding or tendering of Shares or otherwise) of all withholding tax obligations required to be satisfied in respect of the vesting of such Company Restricted Stock pursuant to Section 2.4(b) above, such arrangements to be reasonably satisfactory to Parent; and (b) satisfy or cause to be satisfied, timely and in full including through the withholding of Shares in the case of the DSUs, all tax withholdings required or in respect of any other vesting or payment event in respect of Company Options or DSUs for which the required tax remittance is due prior to the Effective Time, (ii) nothing in the preceding sentence shall limit the ability and right of the Surviving Corporation to satisfy its tax withholding obligations by other means, and (iii) to the extent the Company or Surviving Corporation remits payroll taxes (other than FUTA or the employer portion of FICA) or other required withholdings with respect to the vesting of Company Restricted Shares or in respect of any other vesting or payment event in respect of Company Options or DSUs and there is not a corresponding withholding from amounts payable to the employee or former employee (the amount not withheld, the “shortfall amount”), each of Parent, Sub and Surviving Corporation shall be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, for the benefit of the Surviving Corporation, any such shortfall amount from any cash consideration described in the first sentence of this Section 2.6.

2.7. Transfer Taxes. If any payment 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 is registered, it shall be a condition of payment that the Certificate or Book-Entry Shares

surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the person requesting such payment shall have paid all transfer and other Taxes required by reason of the payment to a person other than the registered holder of the Certificate or Book-Entry Share surrendered or shall have established to the satisfaction of Parent that such Tax either has been paid or is not applicable.

SECTION 3 - REPRESENTATIONS AND WARRANTIES OF COMPANY

Except as (i) set forth on the Disclosure Letter delivered by the Company to Parent on the date hereof (the “Company Disclosure Letter”), the section numbers of which are numbered to correspond to the section numbers of this Agreement to which they refer; provided, however, that (x) an item disclosed for any Section of this Agreement shall be deemed to have been disclosed for each other Section of this Agreement to the extent the relevance of such disclosure to such other Section is reasonably apparent on the face of such disclosure and (y) the mere inclusion of an item in such Company Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item constitutes a Company Material Adverse Effect, and (ii) factual information disclosed in any periodic report filed by the Company with the SEC after January 1, 2011 and publicly available prior to the date of this Agreement (excluding any disclosures under the heading “Risk Factors” and any other disclosures that are predictive or forward-looking in nature), the Company hereby makes the following representations and warranties to Parent and Sub:

3.1. Organization and Qualification.

(a) Each of the Company and each Company Subsidiary is a corporation or other legal entity duly organized, validly existing and in good standing under the Laws of its jurisdiction of organization and has corporate or similar power and authority to own, lease and operate its assets and to carry on its business as now being and as heretofore conducted. Each of the Company and each Company Subsidiary is qualified or otherwise authorized to transact business as a foreign corporation or other organization in all jurisdictions in which such qualification or authorization is required by Law, except for jurisdictions in which the failure to be so qualified or authorized and in good standing would not reasonably be expected to have a Company Material Adverse Effect. “Company Material Adverse Effect” shall mean any change, event, circumstance, effect or development that, individually or in the aggregate with all other changes, events, circumstances, effects or developments that exist on the date of determination, has had a material adverse effect on (i) the assets, properties, business, capitalization, results of operations, or financial condition of the Company and the Company Subsidiaries, taken as a whole, or (ii) the ability of the Company to consummate the transactions contemplated by this Agreement; provided, however, that none of the following shall constitute or be deemed to contribute to a Company Material Adverse Effect or shall be taken into account in determining whether a Company Material Adverse Effect has occurred or would occur: any adverse effect arising out of, resulting from or attributable to (i) (A) the United States or global economy generally or capital or financial markets generally, including changes in interest or exchange rates, (B) political conditions generally of the United States or any other country or jurisdiction in which the Company operates, (C) changes that are the result of factors generally affecting any of the industries in which the Company operates or in which products or services of the Business

are used or distributed, (D) any hostilities, act of war, sabotage, terrorism or military actions, or any escalation or worsening of any such hostilities, act of war, sabotage, terrorism or military actions, or (E) any changes or prospective changes in applicable Law or United States generally accepted accounting principles or interpretation thereof, (ii) the announcement of the transactions contemplated by this Agreement, (iii) any failure by the Company to achieve any earnings or other financial projections or forecasts (including securities analysts published projections), (iv) any change in the trading price or trading volume of the Shares, (v) actions taken with Parent’s written consent or at Parent’s written request, and (vi) the termination for cause or voluntary resignations, retirements or death or disability of any employees of the Company or any Company Subsidiary, except in the case of the foregoing clause (i) to the extent such effect or change is materially disproportionately adverse with respect to the Company as compared to other Persons engaged in the industries of the Company.

(b) The Company has previously provided to Parent true and complete copies of the certificate of incorporation and bylaws or other organizational documents of the Company and each Company Subsidiary as presently in effect, and none of the Company or any Company Subsidiary is in default in the performance, observation or fulfillment of such documents, except, in the case of Company Subsidiaries, such defaults that, in the aggregate, would not reasonably be expected to have a Company Material Adverse Effect.

3.2. Authority to Execute and Perform Agreement. The Company has the corporate power and authority to enter into, execute and deliver this Agreement and, subject, in the case of consummation of the Merger, to the adoption of this Agreement by the holders of the Shares, to perform fully its obligations hereunder. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by the Company Board of Directors. No other action on the part of the Company is necessary to consummate the transactions contemplated hereby (other than adoption of this Agreement by the holders of the Shares). This Agreement has been duly executed and delivered by the Company and (assuming due authorization, execution and delivery by Parent and Sub) constitutes a valid and binding obligation of the Company, enforceable in accordance with its terms, except to the extent enforceability may be limited by the effect of applicable bankruptcy, reorganization, insolvency, moratorium or other Laws affecting the enforcement of creditors’ rights generally and the effect of general principles of equity, regardless of whether such enforceability is considered in a proceeding at Law or in equity.

3.3. Capitalization.

(a) The authorized capital stock of the Company as of the date of this Agreement consists of 99,000,000 Shares and 1,000,000 shares of preferred stock, par value $0.01 per share (“Company Preferred Stock”).

All outstanding Company Options were granted with an exercise price not less than the fair market value of a Share on the date of grant.

For all purposes of this Agreement, the term “Affiliate” when used with respect to any person means

any other person who is an “affiliate” of that first person within the meaning of Rule 405 under the Securities Act.

The Company has no outstanding bonds, debentures, notes or other indebtedness that have the right to vote on any matters on which stockholders may vote.

3.4. Company Subsidiaries.

(a) Section 3.4(a) of the Company Disclosure Letter sets forth a true and complete list of the names, jurisdictions of organization and capitalization of each Company Subsidiary and, for the Company and each Company Subsidiary, the jurisdictions in which it is qualified to do business. Section 3.4(a) of the Company Disclosure Letter also sets forth for each such subsidiary the individuals who comprise the board of directors or comparable body for each such entity. The Company agrees to take, or cause to be taken, the actions necessary so that those individuals will resign and be replaced by individuals specified by Parent effective as of the Effective Time. All issued and outstanding shares or other equity interests of each Company Subsidiary are owned directly by the Company free and clear of any charges, liens, encumbrances, security interests or adverse claims. As used in this Agreement, “Company Subsidiary” means any corporation, partnership or other organization, whether incorporated or unincorporated, of which (i) the Company or any Company Subsidiary is a general partner or (ii) at least 50% of the securities or other interests having voting power to elect a majority of the board of directors or others performing similar functions with respect to such corporation, partnership or other organization are directly or indirectly owned or controlled by the Company or by any Company Subsidiary, or by the Company and one or more Company Subsidiary.

(b) Each Company Subsidiary is a corporation duly organized, validly existing and in good standing (to the extent such concepts are applicable) under the Laws of the jurisdiction of its incorporation, has all requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as now being conducted, and is duly qualified to do business and is in good standing as a foreign corporation (to the extent such concepts are applicable) in each jurisdiction where the character of its properties owned, operated or leased or the nature of its activities makes such qualification necessary, except for such failures to be so organized, qualified or in good standing, individually or in the aggregate, that are not reasonably likely to have a Company Material Adverse Effect. There are not as of the date hereof, and at the Effective Time there will not be, any subscriptions, options, conversion or exchange rights, warrants, repurchase or redemption agreements, or other agreements, claims or commitments of any nature whatsoever obligating any Company Subsidiary to issue, transfer, deliver or sell, or cause to be issued, transferred, delivered, sold, repurchased or redeemed, shares of the capital stock or other securities of the Company or any Company Subsidiary or obligating the Company or any Company Subsidiary to grant, extend or enter into any such agreement. To the knowledge of the Company, there are no stockholder agreements, voting trusts, proxies or other agreements, instruments or understandings with respect to the voting of the capital stock of any Company Subsidiary.

(c) Section 3.4(c) of the Company Disclosure Letter sets forth, for each Company Joint Venture, the interest held by the Company and the jurisdiction in which such Company Joint Venture is organized. Interests in Company Joint Ventures held by the Company are held directly by the Company, free and clear of any charges, liens, encumbrances, security interests or adverse claims. The term “Company Joint Venture” means any corporation or other entity (including partnership, limited liability company and other business association) that is not a Company Subsidiary and in which the Company or one or more Company Subsidiaries owns an equity interest (other than equity interests held for passive investment purposes which are less than 5% of any class of the outstanding voting securities or other equity of any such entity).

(d) The Company does not control, directly or indirectly, any capital stock of any person that is not a Company Subsidiary.

3.5. SEC Reports.

To the knowledge of the Company, the patents and patent applications, registered trademarks and registered copyrights owned by or licensed to the Company and the Company Subsidiaries and referred to above are subsisting and in good standing. With respect to patents, registered trademarks and registered copyrights owned by the Company, the Company has timely paid all maintenance fees and annuities with respect thereto, and, as applicable, timely made such filings, renewals, declarations, statements and certifications required to maintain such items in good standing, except, in each case, where the Company has determined in the exercise of its reasonable business judgment that such patents, registered trademarks and registered copyrights are of no material value to the Company’s business, provided that if such determination was made by the Company at any time after March 31, 2011, or is reasonably expected to be made prior to the Effective Time, such rights are separately identified on Section 3.12(a) of the Disclosure Letter. To the Company’s knowledge, each of the patents and patent applications owned by or licensed to the Company or Company Subsidiaries identifies all of the true and correct inventors of the applicable invention(s) claimed therein, and, to the Company’s knowledge, the Company, Company Subsidiary and each such inventor have complied with all applicable duties of candor and good faith in their interaction with the applicable patent office. To the Company’s knowledge, assignment documents have been executed and filed with relevant Governmental Entities as necessary to transfer to the Company or a Company Subsidiary title to any of the Company’s owned Proprietary Rights consisting of patents, patent applications, registered trademarks, registered copyrights and applications for registration of trademarks and copyrights previously owned by a third party, and to record such transfer. The named inventors of each of the Company’s owned patent applications have assigned the Company’s owned patent applications to the Company. On the expiration date of the Offer, the Company shall provide Parent with a schedule of any Taxes, maintenance fees or actions falling due within 90 days of such expiration with respect to such patents, registered trademarks and registered copyrights, and applications for issuance or registration of any of the foregoing. To the Company’s knowledge, the Company or Company Subsidiary has the rights (1) to obtain and maintain regulatory approvals for products arising under the Proprietary Rights, (2) to enforce all Proprietary Rights against third parties, except where the failure or inability to enforce would not be reasonably likely to have a Company Material Adverse Effect, and (3) with respect to the Proprietary Rights that have been licensed to the Company or Company Subsidiary on an exclusive basis, to obtain, exercise, assert and enforce the rights described in (1) and (2) above with the cooperation, joinder and/or other assistance of the applicable licensor. To the Company’s knowledge, there is no reasonable basis for any claim by any third party that the businesses of the Company or the Company Subsidiaries infringe upon the proprietary rights of others, nor, to the Company’s knowledge, has the

Company or any Company Subsidiary received any charge, complaint, claim, demand, or notice alleging any interference, infringement, misappropriation, or conflict (including any claim that the Company, a Company Subsidiary or any of their affiliates must license or refrain from using any intellectual property rights). To the Company’s knowledge, no third party has infringed upon any of the Proprietary Rights. Section 3.12(a) of the Company Disclosure Letter identifies (i) all issued patents and registered trademarks that have been issued to the Company or a Company Subsidiary, (ii) each pending application therefor submitted by the Company or a Company Subsidiary (iii) where known by the Company, all issued patents, registered trademarks and pending applications therefor owned by a third party who has granted the Company or a Company Subsidiary exclusive rights thereto (iv) each domain name owned by the Company and (v) any application for patent term extension or supplemental protection certificate with respect to (i) and (ii) above.

To the knowledge of the Company, neither the company nor any Company Subsidiary has agreed, or has an obligation, to indemnify any third party for or against any interference, infringement, misappropriation or other conflict involving the exploitation of Proprietary Rights. To the knowledge of the Company, none of the activities of the employees of the Company or any Company Subsidiary on behalf of such entity violates any agreement or arrangement which any such employees have with former employers. To the knowledge of the Company, each employee, contractor or consultant of the Company who has proprietary knowledge of or information relating to the manufacturing processes, or the formulation of the products, of the Company or a Company Subsidiary has executed and delivered to the Company an agreement or agreements restricting such person’s right to use and disclose confidential information of the Company. To the Company’s knowledge, with respect to any patents owned by or licensed to the Company or Company Subsidiary, there is no pending, decided, settled or threatened opposition, interference proceeding, reexamination proceeding, cancellation proceeding, injunction or other proceeding before any Governmental Entity (collectively referred to hereinafter as “Disputes”), challenging the validity, enforceability or ownership of any such patent or the exploitation of such patent and, to the knowledge of the Company, no circumstances or grounds exist that would give rise to such a Dispute. Except as would not be reasonably likely to have a Company Material Adverse Effect, there are no settlements, forbearances to xxx, consents, judgments, or orders or similar obligations to which the Company or any Company Subsidiary is party that: (i) restrict the use by the Company or Company Subsidiary of any Proprietary Rights; (ii) restrict the conduct of the business of the Company or any of its employees; or (iii) grant third parties any material rights under Proprietary Rights. To the knowledge of the Company and except as would not be reasonably likely to have a Company Material Adverse Effect, no material trade secret of the Company has been disclosed or authorized to be disclosed to any third party in violation of confidentiality obligations to the Company and, to the knowledge of the Company, no party to a nondisclosure agreement with the Company is in breach or default thereof. No current or former director, officer, consultant or employee of the Company will, after giving effect to the Offer and the Merger, own any of the Proprietary Rights. To the knowledge of the Company and except as would not be reasonably likely to have a Company Material Adverse Effect, the execution of, the delivery of, the consummation of the Offer and Merger contemplated by, and the performance of the Company’s obligations under, this Agreement will not result in any loss or impairment of any Proprietary Rights. To the knowledge of the Company, neither government funding nor

government, academic or non-profit research facilities were used in the development of any of the patent applications owned by the Company. The representations and warranties in Sections 3.11(d) and 3.12(a) are the sole and exclusive representations and warranties of the Company with respect to Proprietary Rights, and no other representation or warranty in Section 3 hereunder shall be construed to pertain to Proprietary Rights.

(b) With respect to property other than Proprietary Rights, the Company and each Company Subsidiary has all assets, properties, rights and contracts necessary to permit the Company and the Company Subsidiaries to conduct their business as it is currently being conducted, except where the failure to have such assets, properties, rights and contracts would not be reasonably likely to have a Company Material Adverse Effect. The Company and each Company Subsidiary has good, clear and marketable title to all of its properties, interests in properties and assets, real and personal, reflected in the Company Balance Sheet (except properties, interests in properties and assets sold or otherwise disposed of since the date of the Company Balance Sheet in the ordinary course of business consistent with past practice), or with respect to leased properties and assets, valid leasehold interests in such properties and assets, in each case, free and clear of all imperfections of title, restrictions, encroachments, liens and easements, except (i) liens for current Taxes not yet due and payable, that are payable without penalty or that are being contested in good faith by appropriate proceeding and for which an adequate reserve has been established on the Company Balance Sheet in accordance with generally accepted accounting principles, (ii) such imperfections of title, restrictions, encroachments, liens and easements as do not materially detract from or interfere with the use or value of the properties subject thereto or affected thereby, or otherwise materially impair business operations involving such properties, (iii) liens securing debt which are reflected on the Company Balance Sheet and (iv) with respect to leased real property, any liens placed or suffered to be placed on the fee estate underlying such leasehold.

The Company has not received written notice of any pending or threatened eminent domain, condemnation or similar proceeding affecting any Real Property leased by the Company or a Company Subsidiary. To the knowledge of the Company, the property and equipment of the Company and each Company Subsidiary that are used in the operations of business are (i) in good operating condition and repair and (ii) have been maintained in accordance with normal industry practices, except where the failure to maintain such property and equipment would not reasonably be expected to have a Company Material Adverse Effect. Section 3.12(b) of the Company Disclosure Letter lists all Real Property leased by the Company or a Company Subsidiary. Neither the Company nor any Company Subsidiary owns any Real Property.

3.13. Insurance. All policies or binders of material fire, liability, product liability, workers’ compensation, vehicular, directors’ and officers’ and other material insurance held by or on behalf of the Company and the Company Subsidiaries are in full force and effect in all material respects, are reasonably adequate for the businesses engaged in by the Company and the Company Subsidiaries and are in conformity in all material respects with the requirements of all leases or other agreements to which the Company or the relevant Company Subsidiary is a party and, to the knowledge of the Company, are valid and enforceable in accordance with their terms.

Neither the Company nor any Company Subsidiary is in default in any material respect with respect to any provision contained in such policy or binder nor has any of the Company or a Company Subsidiary failed to give any notice or present any material claim under any such policy or binder in due and timely fashion. All premiums for each policy or binder have been paid for the current period, and there are no outstanding premium finance payments due for such period. There are no material outstanding unpaid claims under any such policy or binder.

(f) The Company and the Company Subsidiaries have withheld all material amounts required by Law or contract to be withheld from the wages, salaries or other payments to (i) employees, independent contractors, creditors, stockholders of or consultants to the Company and (ii) any other third party.

U.S. Tax Law).

(j) Neither the Company nor any Company Subsidiary has, within the past seven years, distributed stock of another corporation, or has had its stock distributed by another corporation, in a transaction that was governed, or purported or intended to be governed, in whole or in part, by Sections 355 or 361 of the Code.

Except as provided in this Section 5.2, from the date of this Agreement until the earlier of termination of this Agreement or the Effective Time, the Company shall not and shall cause its Representatives and each Company Subsidiary not to directly or indirectly (i) initiate, solicit or encourage, or take any action to facilitate the making of, any offer or proposal which constitutes or is reasonably likely to lead to an Acquisition Proposal, (ii) enter into any agreement with respect to an Acquisition Proposal, or (iii) engage in negotiations or discussions with, or provide any non-public information or data to, any person (other than Parent or any of its affiliates or representatives) relating to any Acquisition Proposal or grant any waiver or release under any standstill agreement. The Company agrees that any violations of the restrictions set forth in this Section 5.2 by any of its Representatives shall be deemed to be a breach of this Agreement (including this Section 5.2) by the Company. Notwithstanding the foregoing, nothing contained in this Section 5.2 or any other provision hereof shall prohibit the Company or the Company Board of Directors from taking and disclosing to the Company’s stockholders its position with respect to any tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act.

(b) Notwithstanding the foregoing, prior to the acceptance of Shares pursuant to the Offer (the “Acceptance Time”), the Company and its Representatives may furnish information concerning its business, properties or assets to any person pursuant to a confidentiality agreement with terms no less favorable to the Company than those contained in the Confidentiality Agreement and may negotiate and participate in discussions and negotiations with such person concerning an Acquisition Proposal if, but only if, such person has, not resulting from any knowing material violation of this Section 5.2, submitted a written proposal to the Company relating to such Acquisition Proposal which the Board of Directors determines in good faith, after consultation with its financial advisor, is or is reasonably expected to lead to a

Superior Proposal. From and after the date hereof and prior to the Acceptance Time, the Company shall, within forty eight (48) hours, notify Parent in the event that the Company or any Company Subsidiary or Representatives receives (i) any Acquisition Proposal or indication by any person that it is considering making an Acquisition Proposal, (ii) any request for non-public information relating to the Company or any Company Subsidiary related to an Acquisition Proposal, or (iii) any inquiry or request for discussions or negotiations regarding any Acquisition Proposal. The Company shall provide Parent, within such forty eight (48) hour period, with the identity of such Person and a copy of such Acquisition Proposal, indication, inquiry or request (or, where such Acquisition Proposal is not in writing, a description of the material terms and conditions of such Acquisition Proposal, indication, inquiry or request), including any modifications thereto. The Company shall keep Parent reasonably informed, no later than forty eight (48) hours after the occurrence of any changes, developments, discussions or negotiations, of the status of any Acquisition Proposal, indication, inquiry or request (including the material terms and conditions thereof and of any modification thereto), and any material developments, discussions and negotiations, including furnishing copies of any written inquiries, correspondence, and draft documentation. Without limiting the foregoing, the Company shall promptly (and in any event within forty eight (48) hours) notify Parent in writing if it determines to begin providing information or to engage in discussions or negotiations concerning an Acquisition Proposal and shall in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice. The Company shall not, and shall cause the Company Subsidiaries not to, enter into any agreement with any Person subsequent to the date of this Agreement that would restrict the Company’s ability to provide such information to Parent. The Company shall not, and shall cause the Company Subsidiaries not to, terminate, waive, amend or modify any provision of, or grant permission or request under, any standstill or confidentiality agreement to which it or any of the Company Subsidiaries is or becomes a party. The Company will promptly provide to Parent any non-public information concerning the Company or the Company Subsidiaries provided or made available pursuant to this Section 5.2(b) which was not previously provided or made available to Parent. For purposes of this Agreement, a “Superior Proposal” is an unsolicited written Acquisition Proposal, that the Company Board of Directors believes in good faith is bona fide, to acquire more than fifty percent (50%) of the equity securities or consolidated total assets of the Company and the Company Subsidiaries pursuant to a tender or exchange offer, a merger, a consolidation, business combination or recapitalization, or a sale or license of its assets, (A) on terms which the Company Board of Directors determines in its good faith judgment to be more favorable to the holders of Shares than the transactions contemplated by this Agreement (after consultation with its financial and legal advisors), taking into account all the terms and conditions of such proposal and this Agreement, including the timing and likelihood of consummating the transactions contemplated by such proposal and this Agreement, and (B) which the Company Board of Directors has determined to be reasonably capable of being completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal.

(c) Except as set forth herein, neither the Company Board of Directors nor any committee thereof shall (i) withdraw, withhold, qualify or modify, or publicly propose to withdraw, withhold, qualify or modify, the approval or recommendation by the Company Board of Directors or any such committee of the Offer, this Agreement, or the Merger, (ii) approve or recommend or publicly propose to approve or recommend, any Acquisition Proposal (any action referred to in the foregoing clauses (i) and (ii) being referred to as an “Adverse Recommendation

Change”) or (iii) enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or similar agreement (an “Alternative Acquisition Agreement”), providing for the consummation of a transaction contemplated by any Acquisition Proposal (other than a confidentiality agreement referred to in Section 5.2(b) entered into in the circumstances referred to in Section 5.2(b)). The Company shall, promptly following a determination by the Company Board of Directors that an Acquisition Proposal is a Superior Proposal, notify Parent of such determination.

(d) Notwithstanding anything in this Section 5.2 to the contrary, prior to the Acceptance Time, if (i) the Company receives a written Acquisition Proposal from a third party that the Company Board of Directors believes in good faith is bona fide, (ii) a knowing material breach by the Company or a Company Subsidiary of this Section 5.2 has not resulted in the making of such Acquisition Proposal, and (iii) the Company Board of Directors concludes in good faith, after consultation with outside counsel and its financial advisors, such Acquisition Proposal constitutes a Superior Proposal after giving effect to all of the adjustments to the terms of this Agreement which may be committed to by Parent, the Company Board of Directors may, if it determines in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with the fiduciary duties of the Board of Directors to the stockholders of the Company under applicable Law, (A) effect an Adverse Recommendation Change and/or (B) terminate this Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (B), and any purported termination pursuant to the foregoing clause (B) shall be void and of no force or effect, unless in advance of or concurrently with such termination the Company (1) pays the fee required by and pursuant to the terms of Section 8.2 and (2) within two (2) business days following such termination enters into a binding definitive Alternative Acquisition Agreement for such Superior Proposal; and provided, further, that the Company Board of Directors may not effect a change of its recommendation pursuant to the foregoing clause (A) or terminate this Agreement pursuant to the foregoing clause (B) unless (1) the Company or a Company Subsidiary or Representative shall not have materially breached this Section 5.2 in connection with the making of such Acquisition Proposal, (2) the Company shall have provided prior written notice to Parent, at least four (4) business days in advance (the “Notice Period”), of its intention to take such action with respect to such Superior Proposal, which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal), and shall have contemporaneously provided a copy of the proposed Alternative Acquisition Agreement with respect to such Superior Proposal, (3) prior to effecting such Adverse Recommendation Change or terminating this Agreement to enter into a definitive Alternative Acquisition Agreement with respect to such Superior Proposal, the Company shall, and shall cause its Representatives to, during the Notice Period, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to permit Parent to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal, and (4) following any negotiation described in the immediately preceding clause (3), such Acquisition Proposal continues to constitute a Superior Proposal. In the event of any material revisions to the financial terms of the Superior Proposal after the start of the Notice Period, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 5.2 with respect to such new written notice, and the Notice Period shall be deemed to have re-commenced on the date of such new notice. Notwithstanding

the foregoing, if fewer than four (4) business days remains before the then scheduled expiration date of the Offer, the Notice Period with respect to the Company Board of Directors effecting a change of its recommendation pursuant to the foregoing clause (A) shall not apply, provided, however, that, in such a circumstance, the Notice Period with respect to the Company terminating this Agreement pursuant to the foregoing clause (B) shall remain four (4) business days. Any Adverse Recommendation Change shall not change the approval of the Company Board of Directors for purposes of causing any state takeover statute or other Law to be inapplicable to the transactions contemplated by this Agreement, including each of the Offer and the Merger, or to the Tender and Voting Agreements.

(e) Notwithstanding the foregoing, the Company Board of Directors may make an Adverse Recommendation Change in the absence of an Acquisition Proposal if the Company Board of Directors has concluded in good faith, after consultation with its outside counsel, that an Adverse Recommendation Change is necessary to comply with its fiduciary duties, provided, however, that the Company Board of Directors shall not make an Adverse Recommendation Change unless the Company has (A) provided to Parent at least four (4) business days’ prior written notice (or such shorter period as remains prior to one day prior to the scheduled expiration date of the Offer) advising Parent that the Company Board of Directors intends to take such action and specifying the reasons therefore in reasonable detail and (B) during such four (4) business day, or shorter, period, if requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner that obviates the need or reason for the Adverse Recommendation Change.

Prior to the Effective Time, the Company shall cooperate with Parent and use commercially reasonable efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of The Nasdaq Stock Market to enable the delisting by the Surviving Corporation of the Shares from The Nasdaq Stock Market and the deregistration of the Shares under the Exchange Act promptly after the Effective Time. Parent will use commercially reasonable efforts to cause the Surviving Corporation to file with the SEC (a) a Form 25 on the Closing Date and (b) a Form 15 on the first business day that is at least ten (10) days after the date the Form 25 is filed (such period between the Form 25 filing date and the Form 15 filing date, the “Delisting Period”). If the Surviving Corporation is reasonably likely to be required to file any reports pursuant to the Exchange Act during the Delisting Period, the Company will deliver to Parent at least five (5) business days prior to the Closing a substantially final draft of any such reports reasonably likely to be required to be filed during the Delisting Period (“Post-Closing SEC Reports”). The Post-Closing SEC Reports provided by the Company pursuant to this Section 6.3 will (i) not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading and (ii) comply in all material respects with the provisions of applicable Laws.

6.4. Access to Information. Prior to the Effective Time, Parent shall be entitled, through its employees and representatives, to have such access to the assets, properties, business and operations of the Company and the Company Subsidiaries in connection with Parent’s investigation of the Company with respect to the transactions contemplated hereby except as prohibited by applicable Law. Any such investigation and examination shall be conducted at reasonable times during normal business hours upon reasonable advance notice and under reasonable circumstances so as to limit disruption to or impairment of the Company’s business; provided, however, such investigation and examination shall not include the right to conduct any sampling or testing, including any so-called Phase II testing, of the properties. No investigation by Parent shall diminish or obviate any of the representations, warranties, covenants or agreements of the Company contained in this Agreement. The Company shall furnish the representatives of Parent during such period with all such information and copies of such documents concerning the affairs of the Company as such representatives may reasonably request and cause its Representatives to cooperate fully with such representatives of Parent in connection with such investigation. The information and documents so provided shall be subject to the terms of the Confidentiality Agreement. Notwithstanding the foregoing, neither the Company nor any of its Subsidiaries shall be required to provide access to or disclose information designated as competitively sensitive or where the Company reasonably determines that such access or disclosure would jeopardize the attorney-client privilege of the Company or

any of its Subsidiaries or contravene any Law or any contract entered into prior to the date of this Agreement and listed in Section 6.4 of the Disclosure Letter to which the Company or any of its Subsidiaries is a party.

6.5. Public Disclosure. The initial press release concerning the Offer and the Merger shall be a joint press release and, thereafter, so long as this Agreement is in effect, neither Parent, Sub nor the Company will disseminate any press release or other announcement concerning the Merger, the Offer or this Agreement or the other transactions contemplated by this Agreement to any third party, except as may be required by Law or by any listing agreement with a national stock exchange, without the prior consent of each of the other parties hereto, which consent shall not be unreasonably withheld conditioned or delayed. Notwithstanding the foregoing, the Company may disseminate press releases or other announcements regarding an Acquisition Proposal or Adverse Recommendation Change in accordance with the terms of Section 5.2 without the prior consent of Parent or Sub. The parties have agreed to the text of the joint press release announcing the execution of this Agreement. Notwithstanding the foregoing, without prior consent of the other party, each party (a) may communicate information that is not confidential information of the other party with financial analysts, investors and media representatives in a manner consistent with its past practice in compliance with applicable Law and (b) may disseminate material substantially similar to material included in a press release or other document previously approved for external distribution by the other parties. Each party agrees to promptly make available to the other parties copies of any written communications made without prior consultation with the other parties.

6.6. Regulatory Filings; Reasonable Efforts.

(a) As promptly as practicable after the date hereof and in compliance with all applicable regulatory requirements, each of Parent, Sub and the Company shall make all filings, notices, petitions, statements, registrations, submissions of information, application or submission of other documents required by any Governmental Entity in connection with the Offer, the Merger and the other transactions contemplated hereby, including, without limitation: (i) Notification and Report Forms with the United States Federal Trade Commission and the Antitrust Division of the United States Department of Justice as required by the HSR Act, (ii) filings required by the merger notification or control Laws of any applicable jurisdiction, as agreed by the parties hereto, and (iii) any filings required under the Securities Act, the Exchange Act, any applicable state or securities or “blue sky” Laws and the securities Laws of any foreign country, or any other applicable Laws or rules and regulations of any Governmental Entity relating to the Offer and the Merger. Each of Parent and the Company will cause all documents that it is responsible for filing with any Governmental Entity under this Section 6.6 to comply in all material respects with all applicable Laws and rules and regulations of any Governmental Entity.

(b) Each of Parent, Sub, and the Company shall promptly supply the other with any information which may be reasonably required in order to effectuate any filings or applications pursuant to this Section 6.6.

(c) Each of Parent, Sub and the Company will notify the others promptly upon the receipt of: (i) any communication or comments from any officials of any

Governmental Entity in connection with any filings made pursuant hereto and (ii) any request by any officials of any Governmental Entity for amendments or supplements to any filings made pursuant to, or information provided to comply in all material respects with, any applicable Laws and rules and regulations of any Governmental Entity. Whenever any event occurs that is required to be set forth in an amendment or supplement to any filing made pursuant to Section 6.6(a), Parent, Sub or the Company, as the case may be, will promptly inform the others of such occurrence and cooperate in filing with the applicable Governmental Entity such amendment or supplement.

(d) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Offer, the Merger and the other transactions contemplated hereby, including complying in all material respects with all applicable Laws and with all rules and regulations of any Governmental Entity and using its reasonable best efforts to accomplish the following: (i) the causing of all the conditions set forth in SECTION 7 and in all of the Offer Conditions to be satisfied and to consummate and make effective the Offer, the Merger and the other transactions contemplated hereby, (ii) the obtaining of all reasonably requested actions or nonactions, waivers, consents, clearances, approvals, orders and authorizations from Governmental Entities and the making of all reasonably requested registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any), (iii) the obtaining of all reasonably requested consents, approvals or waivers from third parties, (iv) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (v) the execution or delivery of any additional instruments necessary to consummate the transactions contemplated hereby, and to carry out fully the purposes of, this Agreement. In connection with and without limiting the foregoing, the Company and its Board of Directors shall, if any state takeover statute or similar statute or regulation is or becomes applicable to the Offer, the Merger, this Agreement or any of the other transactions contemplated hereby, use their reasonable best efforts to ensure that the Offer, the Merger and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Offer, the Merger, this Agreement and the other transactions contemplated hereby. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of the Company, Parent and Sub shall use their reasonable best efforts to take, or cause to be taken, all such necessary actions. Parent shall cause Sub to fulfill all Sub’s obligations under, and pursuant to, this Agreement. Nothing in this Agreement shall require Parent, the Surviving Corporation or any other subsidiary of Parent to sell, hold separate, license or otherwise dispose of any assets or conduct their business in a specified manner, or agree or proffer to sell, hold separate, license or otherwise dispose of any assets or conduct their business in a specified manner, or permit or agree to the sale, holding separate, licensing or other disposition of, any assets of Parent, the Surviving Corporation or any other subsidiary of Parent or the Company, whether as a condition to obtaining any approval from, or to avoid potential

litigation or administrative action by, a Governmental Entity or any other person or for any other reason.

6.7. Notification of Certain Matters; Litigation. Each party shall give prompt notice to the other parties of (a) the occurrence or non-occurrence of any event of which such party has knowledge the occurrence or non-occurrence of which would cause any representation or warranty made by such party in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Effective Time, (b) any Offer Condition that is unsatisfied at any time from the date hereof to the Acceptance Time of which such party has knowledge (other than the condition contained in clause (i) of the first paragraph of the Offer Conditions, as to which such notice shall be given if such condition is unsatisfied as of any scheduled expiration date of the Offer), and (c) any material failure of such party or any of its Representatives to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder of which such party has knowledge; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties, the conditions to the obligations of the parties under this Agreement or the remedies available to the party receiving such notification. Without limiting the foregoing, each party shall, within twenty-four (24) hours after it has notice of any of the following notify the other parties of (i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement, (ii) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement, and (iii) any actions, suits, claims, investigations or proceedings instituted or threatened against such party or any of its directors, officers or Affiliates, including by any stockholder of such party, before any court or Governmental Entity, relating to or involving or otherwise affecting the such party or any of its Subsidiaries which, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to this Agreement or relating to this Agreement or the transactions contemplated hereby, or seeking damages or discovery in connection with such transactions. Parent shall have the right to participate in, but not control, the defense of any such actions, suits, claims, investigations or proceedings under clause (iii) above with respect to the Company, and the Company shall consult with Parent regarding the defense or settlement of any such actions, suits, claims, investigations or proceedings and shall consider Parent’s views with respect to such actions, suits, claims, investigations or proceedings.

6.8. Indemnification.

(a) Parent agrees that any rights to indemnification or exculpation (including the payment of reasonable attorney’s fees and expenses in advance of the final disposition of any claim, action, suit, proceeding or investigation) now existing in favor of the current or former directors or officers of the Company and the current or former directors or officers of each Company Subsidiary (the “Indemnified Parties” and, each, an “Indemnified Party”) as provided in their respective organizational documents, in effect as of the date hereof, with respect to matters occurring at or prior to the Effective Time shall survive the Merger and shall continue in full force and effect for a period of six (6) years after the Effective Time, and Parent guarantees any such obligations of the Surviving Corporation. During such period, Parent shall not, nor shall it permit the Surviving Corporation to, amend, repeal or otherwise modify such provisions for indemnification in any manner that would materially and adversely affect the rights

thereunder of individuals who at any time on or prior to the Effective Time were directors or officers of the Company or directors or officers of any of Company Subsidiary in respect of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement), unless such modification is required by Law; provided, however, that in the event any claim or claims are asserted or made either prior to the Effective Time or within such six (6) year period, all rights to indemnification in respect of any such claim or claims shall continue until disposition of any and all such claims. Parent guarantees the payment of any obligation of the Surviving Corporation to indemnify an Indemnified Party.

(b) Subject to the next sentence, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, (i) maintain, at no expense to the beneficiaries, in effect for six (6) years from the Effective Time, the current policies of the directors’ and officers’ liability insurance maintained by the Company (the “Current D&O Insurance”) with respect to matters existing or occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), so long as the annual premium therefor would not be in excess of three hundred percent (300%) of the last annual premium paid prior to the Effective Time (such three hundred percent (300%), the “Maximum Premium”), or (ii) purchase a six (6) year extended reporting period endorsement with respect to the Current D&O Insurance (a “Reporting Tail Endorsement”) and maintain such endorsement in full force and effect for its full term, provided, however, that prior to the Surviving Corporation taking any actions in clauses (i) or (ii) above, Parent shall be provided the opportunity to purchase, in lieu thereof, a substitute policy with the same coverage limits and substantially similar terms as in the Reporting Tail Endorsement proposed to be purchased by the Surviving Corporation. If the Company’s or the Surviving Corporation’s existing insurance expires, is terminated or canceled during such six (6) year period or exceeds the Maximum Premium, the Surviving Corporation shall obtain, and Parent shall cause the Surviving Corporation to obtain, as much directors’ and officers’ liability insurance as can be obtained for the remainder of such period for an annualized premium not in excess of the Maximum Premium, on terms and conditions no less advantageous to the Indemnified Parties than the Company’s existing directors’ and officers’ liability insurance.

(c) In the event that Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or a substantial portion of its properties and other assets to any Person, then, and in each such case, Parent or the Surviving Corporation, as applicable, shall cause proper provision to be made so that such successors and assigns shall assume the obligations set forth in this Section 6.8.

(d) The provisions of this Section 6.8 are intended to be for the benefit of, and will be enforceable by, each Indemnified Party, his or her heirs and his or her Representatives and are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have from the Company or any other Person by contract or otherwise.

6.9. Directors.

(a) Promptly upon the first acceptance for payment pursuant to the Offer of Shares that represent at least a majority of the issued and outstanding Shares, and the transfer of funds to a paying agent to cover the Closing Amount with respect to such Shares, Parent shall be entitled to designate such number of directors on the Company Board of Directors as will give Parent, subject to compliance with Section 14(f) of the Exchange Act, representation on the Company Board of Directors equal to at least that number of directors, rounded up to the next whole number, which is the product of (x) the total number of directors on the Company Board of Directors (giving effect to the directors elected pursuant to this sentence) multiplied by (y) the percentage that (I) such number of Shares so accepted for payment by Sub and with respect to which funds were transferred to a paying agent to cover the Closing Amount plus the number of Shares otherwise owned by Parent, Sub, or any other subsidiary of Parent bears to (II) the number of such Shares outstanding, and the Company shall, at such time, cause Parent’s designees to be so elected; provided, however, that in the event that Parent’s designees are appointed or elected to the Company Board of Directors, until the Effective Time, the Company Board of Directors shall have at least three (3) directors who are directors on the date of this Agreement and who are not officers of the Company and are independent directors for purposes of The Nasdaq Stock Market listing requirements (the “Independent Directors”); and provided, further, that, in such event, if the number of Independent Directors shall be reduced below three (3) for any reason whatsoever, any remaining Independent Directors (or Independent Director, if there shall be only one remaining) shall be entitled to designate persons to fill such vacancies who shall be deemed to be Independent Directors for purposes of this Agreement or, if no Independent Directors then remain, the other directors shall designate three persons to fill such vacancies who are not officers or affiliates of the Company and are independent directors for purposes of The Nasdaq Stock Market listing requirements, Parent or Sub, and such persons shall be deemed to be Independent Directors for purposes of this Agreement. At such time, the Company shall, upon Parent’s request, also cause persons elected or designated by Parent to constitute the same percentage (rounded up to the next whole number) as is on the Company Board of Directors of (i) each committee of the Company Board of Directors, (ii) each board of directors (or similar body) of each of the Company’s Subsidiaries, and (iii) each committee (or similar body) of each such board, in each case only to the extent required by applicable Law or the rules of any stock exchange on which the Shares are listed. Subject to applicable Law, the Company shall take all action requested by Parent necessary to effect any such election, including mailing to its stockholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company shall make such mailing with the mailing of the Schedule 14D-9 (provided that Parent and Sub shall have provided to the Company on a timely basis, and shall be solely responsible for, all information required to be included in the Information Statement with respect to Parent’s and Sub’s designees). In connection with the foregoing, the Company shall promptly, at the option of Sub, either increase the size of the Company Board of Directors or obtain the resignation of such number of its current directors, or both, as is necessary to enable Sub’s designees to be elected or appointed to the Company Board of Directors as provided above.

(b) Notwithstanding anything in this Agreement to the contrary, if Parent’s designees constitute a majority of the Company Board of Directors after the Acceptance Time and prior to the Effective Time, then the affirmative vote of a majority of the Independent

Directors (or if only one (1) exists, then the vote of such Independent Director) shall be required to (i) amend or terminate this Agreement by the Company, (ii) exercise or waive any of the Company’s rights, benefits or remedies hereunder, if such action would materially and adversely affect holders of Shares other than Parent or Sub, (iii) amend the certificate of incorporation or bylaws of the Company, or (iv) take any other action of the Company Board of Directors under or in connection with this Agreement or the transactions contemplated hereby; provided, however, that if there shall be no Independent Directors as a result of such persons’ deaths, disabilities or refusal to serve, then such actions may be effected by majority vote of the entire Company Board of Directors.

6.10. 401(k). Except with the prior written consent of Parent, during the period from the date of this Agreement to the Effective Time, the Company shall not (i) make any contribution to the Company’s 401(k) plan other than as consistent with past practice or required under the terms of such plan as in effect on the date of this Agreement, or (ii) make any required contribution to the Company’s 401(k) plan in Shares. If requested by Parent in writing prior to the scheduled expiration date of the Offer, the Company shall, not later than the day before the day on which the Acceptance Time occurs (but subject to the occurrence of the Acceptance Time), terminate the Company’s 401(k) plan.

6.11. Employee Benefits.

(a) Each employee of the Company as of the Acceptance Time (i) who is a participant in the Company’s performance-based Incentive Compensation Plan (the “Incentive Compensation Plan”) shall be entitled to receive from the Company, the Surviving Corporation or the Parent, as the case may be, the amount of any bonus payable to such employee under the Incentive Compensation Plan for calendar year 2011, calculated assuming target achievement by the Company and such employee of all applicable performance goals, if any, and (ii) who is a participant in the Company’s Account Manager, Regional Sales Director and National Sales Director Field Sales Incentive Compensation Plan for Trimester 3 (September — December 2011) (the “Sales Incentive Compensation Plan” and together with the Incentive Compensation Plan, the “IC Plans”) shall be entitled to receive from the Company, the Surviving Corporation or the Parent, as the case may be, the greater of (y) the amount of any bonus payable to such employee under the Sales Incentive Compensation Plan for such trimester, calculated assuming target achievement by the Company and such employee of all applicable performance goals, if any, and (z) the actual amount of goal attainment for such employee under such plan. The amount of bonus payable under this Section 6.11(a)(i) or (ii) herein shall be paid at the earlier of (i) such time as such bonus otherwise would have been paid to such employee by the Company consistent with past practice and (ii) such time as the employee is terminated by the Surviving Corporation or Parent. Section 6.11(a) of the Company Disclosure Letter sets forth the 2011 target bonus amounts and percentages for each employee as of the date of this Agreement. In addition, each such employee shall have an aggregate potential bonus opportunity for calendar year 2012 no less favorable than the percentage bonus opportunity available to such employee in 2011, as set forth in Section 6.11(a) of the Company Disclosure Letter.

(b) At least until the first anniversary of the Effective Time, each employee of the Company who continues to be employed by the Surviving Corporation during such period (a “Continuing Employee”) shall be provided a base salary at a rate no less than the rate of the

annual base salary provided to such Continuing Employee on the date hereof and employee benefits that are substantially comparable in the aggregate to the benefits provided to similarly situated Parent employees based on levels of responsibility.

(c) Each Continuing Employee who participates in (or is otherwise eligible for) any such Company plan immediately prior to the Acceptance Time will receive service credit for all periods of employment with the Company or Company Subsidiaries, as applicable, prior to the Effective Time for purposes of vesting, eligibility and (only for purposes of determining the amount of vacation and Severance (as defined in Section 6.11(d) below)) benefit levels under any Parent employee plan in which such employee participates after the Effective Time, to the same extent and for the same purposes thereunder as such service was recognized under an analogous Company compensation plan in effect on the date hereof. If on or after the Effective Time, any Continuing Employee becomes covered under any benefit plan providing medical, dental, health, pharmaceutical or vision benefits (a “Successor Plan”), other than the plan in which he or she participated immediately prior to the Effective Time (a “Prior Plan”), Parent shall use its commercially reasonable efforts to ensure that (i) such Continuing Employee shall not be subject to any restrictions or limitations with respect to pre-existing condition exclusions, waiting periods and actively-at-work requirements (except to the extent such exclusions or requirements were applicable under the corresponding Prior Plan) and (ii) such Continuing Employee shall be permitted to take into account any eligible expenses incurred by such employee and his or her covered dependents during the plan year in which the employee elects to be covered under the Successor Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and/or his or her covered dependents for that year, to the extent that such expenses were incurred during the applicable plan year in which such employee or covered dependent was covered under a corresponding Prior Plan.

(d) Parent shall or shall cause the Surviving Corporation to provide severance benefits (“Severance”) to each Continuing Employee whose employment is terminated by the Surviving Corporation without Cause (as defined in this Section 6.11(d)) or by reason of a reduction in the workforce or job elimination, in each case at any time prior to the first anniversary of the Effective Time, other than an employee who is eligible for participation in the Company’s Executive Severance Pay Program, or who has a binding contractual right to severance benefits pursuant to any agreement with the Company, (each a “Terminated Employee”), subject to the Terminated Employee’s providing a timely and effective release of claims in favor of the Company, the Surviving Corporation and the Parent (the “Employee Release”). Severance shall be paid to such Terminated Employee in an amount equal to twelve weeks Base Pay (as defined in this Section 6.11(d)) plus an additional week of base pay for each year of continuing service by such Terminated Employee to the Company, the Surviving Corporation, Parent and its Affiliates. For the avoidance of doubt, a Terminated Employee’s years of continuing service shall be rounded up to the nearest whole year in calculating the number of additional weeks of Base Pay that are added to the twelve weeks of Base Pay. Severance shall be paid to each Terminated Employee in the form of a lump sum cash payment, as soon as reasonably practicable (taking into account the requirement of a release) following the Terminated Employee’s date of termination. For purposes of this Section 6.11(d), “Base Pay” shall mean the weekly base salary of the Terminated Employee on the date of his or her termination of employment. No such Severance payments shall be made if the Terminated

Employee is terminated for Cause. “Cause” shall mean (i) fraud, misappropriation or embezzlement against the Surviving Corporation, Parent or its Affiliates, (ii) falsification of records or similar acts, (iii) gross neglect of or willful failure to perform substantial job duties, (iv) commission of a felony or other crime involving dishonesty, violence or moral turpitude, or (v) insubordination, defined as the refusal by an employee to follow management’s rational and lawful instructions regarding a job-related matter.

(e) If a Terminated Employee elects COBRA continuation coverage, then for a period of three months beginning on the first day of the month immediately following the month of the Terminated Employee’s date of termination or until the Terminated Employee’s eligibility for such coverage ceases, if earlier, Parent shall or shall cause the Surviving Corporation to (i) pay the full cost of such coverage or (ii) if Parent determines that payment of such cost could result in any penalty or tax to Parent or the Surviving Corporation, pay additional severance to the Terminated Employee in an amount equal to such cost. In addition, Parent shall or shall cause the Surviving Corporation to provide outplacement services to each Terminated Employee for a period of six months and for each employee who is eligible for participation in the Company’s Executive Severance Pay Program for a period of twelve months. All payments to or on behalf of a Terminated Employee under this Section 6.11 shall be conditioned on the employee providing an Employee Release.

(f) Nothing contained herein, whether express or implied, shall be construed or applied so as to require Parent or any of its subsidiaries to continue any plan or to continue the employment of any Person. No provision of this Agreement shall be construed to create any right to any compensation or benefits on the part of any Continuing Employee or other future, present or former employee of Parent, the Surviving Corporation or their respective subsidiaries or be deemed to make any employee of the parties or their respective subsidiaries a third party beneficiary of this Agreement, including this Section 6.11, or any rights relating hereto. No provision of this Section 6.11 is intended to, or shall, constitute the establishment or adoption of or an amendment to any employee benefit plan for purposes of ERISA or otherwise or shall be construed or applied so as to result in a duplication of benefits or payments.

6.12. State Takeover Laws. If any “fair price,” “business combination” or “control share acquisition” statute or other similar statute or regulation is or becomes applicable to any of the transactions contemplated by this Agreement, the parties hereto shall use their respective commercially reasonable efforts to (a) take such actions as are reasonably necessary so that the transactions contemplated hereunder may be consummated as promptly as practicable on the terms contemplated hereby and (b) otherwise take all such actions as are reasonably necessary to eliminate or minimize the effects of any such statute or regulation on such transactions.

6.13. FIRPTA Certificate. Prior to each of the Acceptance Time and the Effective Time, the Company shall execute and deliver to Parent and Sub a certificate (in a form reasonably acceptable to Parent and Sub) conforming to the requirements of Treasury Regulations Sections 1.1445-2(c)(3) and 1.897-2(h).

SECTION 7 - CONDITIONS PRECEDENT TO THE OBLIGATION OF PARTIES TO CONSUMMATE THE MERGER

7.1. Conditions to Obligations of Each Party to Effect the Merger. The respective obligations of each party to this Agreement to effect the Merger shall be subject to the satisfaction or written waiver at or prior to the Closing Date of the following conditions:

(a) Stockholder Approval. This Agreement shall have been adopted by the requisite vote of the holders of the Shares, to the extent required pursuant to the requirements of the certificate of incorporation and the DGCL.

(b) Statutes; Court Orders. No statute, rule, executive order or regulation shall have been enacted, issued, enforced or promulgated by any Governmental Entity which prohibits the consummation of the Merger, and there shall be no order or injunction of a court of competent jurisdiction in effect preventing or making illegal the consummation of the Merger.

(c) Consummation of the Offer. The Shares validly tendered and not withdrawn pursuant to the Offer shall have been accepted for payment pursuant to the Offer and the terms of this Agreement; provided, however, that neither Parent nor Sub shall be entitled to assert the failure of this condition if, in breach of this Agreement or the terms of the Offer, Sub shall have failed to purchase any of the Shares validly tendered and not withdrawn pursuant to the Offer.

SECTION 8 - TERMINATION, AMENDMENT AND WAIVER

8.1. Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time before the Effective Time, whether before or after stockholder approval thereof:

(a) By mutual written consent of Parent and the Company duly authorized by the Board of Directors of Parent and the Company Board of Directors; or

(b) By either Parent or the Company:

(i) if a court of competent jurisdiction or other Governmental Entity shall have issued an order, decree or ruling or taken any other action, and such order, decree or ruling or other action shall have become final and non-appealable, or there shall exist any statute, rule or regulation, in each case, permanently restraining, enjoining or otherwise prohibiting (collectively, “Restraints”) the consummation of the Offer or the Merger; provided, however, that the party seeking to terminate this Agreement pursuant to this Section 8.1(b)(i) shall have used its reasonable best efforts to prevent the entry of and to remove such Restraints and complied with Section 6.6; or

(ii) if the Acceptance Time has not occurred by the date that is four (4) months after the date hereof (the “Outside Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b)(ii) shall not be available to any party whose action or failure to fulfill any obligation under this Agreement has been the principal cause of, or resulted in, the failure of the Acceptance Time to occur by such date; or

(c) By Parent if, (i) there has been a breach by the Company of, or inaccuracy in, any representation, warranty, covenant or agreement of the Company set forth in this Agreement (A) which would give rise to the failure of a condition set forth in clause (c) or (d) of Annex I and (B) such breach or inaccuracy is not capable of being cured; or (ii) due to an occurrence or circumstance that has resulted in a failure to satisfy any Offer Condition that is not capable of being cured, Sub shall have allowed the Offer to terminate, without having accepted any Shares for payment, unless such occurrence or circumstance shall have been caused by or resulted from the failure of Parent or Sub to perform, in any material respect, any of their covenants or agreements contained in this Agreement or the breach by Parent or Sub of any of their representations or warranties contained in this Agreement; provided, however, that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.1(c) if Parent is then in material breach of any of its representations, warranties, covenants or agreements hereunder; or

(d) By the Company if, prior to the Acceptance Time, there has been a breach by Parent or Sub of, or any inaccuracy in, any representation, warranty, covenant or other agreement of Parent or Sub set forth in this Agreement, which breach or inaccuracy is reasonably expected to prevent Parent or Sub from performing in all material respects its obligations and covenants required to be performed by it under this Agreement (and such breach or inaccuracy is not capable of being cured); provided, however, that the Company shall not have the right to terminate this Agreement pursuant to this Section 8.1(d) if the Company is then in material breach of any of its representations, warranties, covenants or agreements hereunder; or

(f) At any time prior to the Acceptance Time, by the Company, if the Company has received a Superior Proposal, which, after giving effect to all of the adjustments that may be committed to by Parent pursuant to Section 5.2, the Company Board of Directors determines in good faith (after consultation with its financial advisors) continues to constitute a Superior Proposal, provided the Company shall not have knowingly materially violated or breached any of its obligations under Section 5.2 in connection with the making of such Superior Proposal; or

(g) By Parent, if upon a vote at a duly held meeting to obtain the Company Stockholder Approval, such approval is not obtained, provided, however, that Parent may not terminate this Agreement under this Section 8.1(g) if the Shares owned by Parent or any of its subsidiaries shall not have been voted in favor of adopting this Agreement.

8.2. Effect of Termination.

(a) Any termination of this Agreement under Section 8.1 hereof will be effective immediately upon the delivery of a written notice of the terminating party to the other party hereto and, if then due, payment of the Termination Fee. In the event of termination of this Agreement as provided in Section 8.1 hereof, this Agreement shall forthwith become null and void and be of no further force or effect and there shall be no liability on the part of Parent, Sub or the Company (or any of their respective directors, officers, employees, stockholders, agents or representatives), except as set forth in the penultimate sentence of Section 6.4, SECTION 8 and SECTION 9, each of which shall remain in full force and effect and survive any termination of this Agreement; provided, however, that nothing herein shall relieve any party from liability for fraud or intentional breach of any of its representations, warranties, covenants or agreements set forth in this Agreement (it being understood that the failure of Parent or Sub to accept for payment and pay for the Shares validly tendered and not withdrawn pursuant to the Offer promptly following the Expiration Date in the event that all Offer Conditions have been satisfied or, to the extent permitted, waived, as of the Expiration Date shall be deemed an intentional breach by Parent and Sub pursuant to this Agreement). Notwithstanding anything to the contrary in this Agreement, in no event shall the Company be required to pay the Termination Fee on more than one occasion.

(b) If Parent shall have terminated this Agreement pursuant to Section 8.1(e), the Company shall promptly pay Parent a termination fee (the “Termination Fee”) of $10,000,000, but in no event later than two (2) business days after the date of receipt of Parent’s termination notice. If the Company terminates this Agreement pursuant to Section 8.1(f), it shall, in connection with and as a condition to such termination, pay Parent the Termination Fee. If Parent terminates this Agreement pursuant to Section 8.1(c)(ii) due to the failure to satisfy the Minimum Condition or 8.1(c)(i) due to a material breach of Section 5.2, or if the Company terminates pursuant to Section 8.1(b)(ii), and in each case at or prior to the time of termination an Acquisition Proposal has been made (and, with regard to any termination pursuant to Section 8.1(c)(ii), such Acquisition Proposal has been publicly made), then the Company shall pay Parent the Termination Fee upon signing a definitive agreement for a transaction relating to an Acquisition Proposal (or, if earlier, the consummation of a transaction contemplated by an Acquisition Proposal), provided such signing (or, if earlier, such consummation) occurs within nine (9) months of the termination date. All amounts due hereunder shall be payable by wire transfer in immediately available funds to such account as Parent may designate in writing to the Company. If the Company fails to promptly make any payment required under this Section 8.2(b) and Parent commences a suit to collect such payment, the Company shall indemnify Parent for its fees and expenses (including attorneys fees and expenses) incurred in connection with such suit and shall pay interest on the amount of the payment at the prime rate of Bank of America (or its successors or assigns) in effect on the date the payment was payable pursuant to this Section 8.2(b). For purposes of this Section 8.2(b) only, the term “Acquisition Proposal” shall have the meaning assigned to such term in Section 5.2(a) except that all references to “15%” therein shall be deemed to be references to “50%.”

8.3. Fees and Expenses. Except as set forth in Section 8.2, all fees, costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the Merger is consummated.

8.4. Amendment. Subject to applicable Law and as otherwise provided in the Agreement, this Agreement may be amended, modified and supplemented in any and all respects, whether before or after any vote of the stockholders of the Company contemplated hereby, by written agreement of the parties hereto, by action taken by their respective Boards of Directors, but after the Tender Completion Time, no amendment shall be made which decreases the Merger Consideration and, after the approval of this Agreement by the stockholders, no amendment shall be made which by Law requires further approval by such stockholders without obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.5. Waiver. At any time prior to the Effective Time, either party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto or (b) waive compliance with any of the agreements of the other party or any conditions to its own obligations, in each case only to the extent such obligations, agreements and conditions are intended for its benefit; provided, that any such extension or waiver shall be binding upon a party only if such extension or waiver is set forth in a writing executed by such party.

9.3. Entire Agreement.

9.4. Governing Law. This Agreement and all actions arising under or in connection therewith shall be governed by and construed in accordance with the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of law thereof.

9.5. Binding Effect; No Assignment; No Third-Party Beneficiaries.

(a) This Agreement shall not be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties, except that Sub may assign, at no additional cost or expense to the Company, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to (i) Parent, (ii) to Parent and one or more direct or indirect wholly-owned subsidiaries of Parent, or (iii) to one or more direct or indirect wholly-owned subsidiaries of Parent (each, an “Assignee”). Any such Assignee may thereafter assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more additional Assignees; provided, however, that in connection with any assignment to an

Assignee, Parent and Sub (or the assignor) shall agree to remain liable for the performance by Parent and Sub (and such assignor, if applicable) of their obligations hereunder. Subject to the preceding sentence, but without relieving any party hereto of any obligation hereunder, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

(b) Nothing in this Agreement, express or implied, is intended to or shall confer upon any person other than Parent, Sub and the Company and their respective successors and permitted assigns any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than (i) Section 6.8, which shall confer third-party beneficiary rights to the parties identified therein, and (ii) the right of the Company’s stockholders to receive the Closing Amount at the Acceptance Time or the Merger Consideration at the Effective Time.

9.6. Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by facsimile or by an electronic scan delivered by electronic mail), each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. This Agreement may be executed and delivered by facsimile or by an electronic scan delivered by electronic mail.

9.7. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable. The parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

9.8. Submission to Jurisdiction; Waiver. Each of the Company, Parent and Sub irrevocably agrees that any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby or for recognition and enforcement of any judgment in respect hereof brought by the other party hereto or its successors or assigns shall be brought and determined in the state courts of the State of Delaware or, the United States District Court for the District of Delaware, and each of the Company, Parent and Sub hereby irrevocably submits with regard to any action or proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of the Company, Parent and Sub 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 Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) 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 (c) to the fullest extent permitted by applicable Law, that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper and (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

9.9. Specific Performance. Notwithstanding anything in this Agreement to the contrary, the parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at Law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any state court of the State of Delaware or the United States District Court for the District of Delaware, this being in addition to any other remedy to which they are entitled at Law or in equity.

9.10. Rules of Construction; Certain Definitions.

No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.

9.12. Waiver of Jury Trial. EACH OF PARENT, COMPANY AND SUB HEREBY IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENT OR ACTION RELATED HERETO OR THERETO.

WHEREAS, capitalized terms used in this Agreement and not defined have the meaning given to such terms in the Merger Agreement.

NOW, THEREFORE, in contemplation of the foregoing and in consideration of the mutual agreements, covenants, representations and warranties contained herein and intending to be legally bound hereby, the parties hereto agree as follows:

1. Certain Covenants.

1.1 Lock-Up. Subject to Section 1.5, except as contemplated by the Merger Agreement, Stockholder hereby covenants and agrees that between the date hereof and the Termination Date, Stockholder will not (a) directly or indirectly, sell, transfer, assign, pledge, hypothecate, tender, encumber or otherwise dispose of or limit its right to vote in any manner any of the Securities, or agree to do any of the foregoing, or (b) take any action which would have the effect of preventing or disabling Stockholder from performing its obligations under this Agreement. Notwithstanding the foregoing, in connection with any transfer not involving or

Annex II - 1

relating to any Acquisition Proposal (as defined in the Merger Agreement), Stockholder may transfer any or all of the Securities as follows: (i) in the case of a Stockholder that is an entity, to any subsidiary, partner or member of Stockholder, and (ii) in the case of an individual Stockholder, to Stockholder’s spouse, ancestors, descendants, estate or any trust for any of their benefits or to a charitable trust; provided, however, that in any such case, prior to and as a condition to the effectiveness of such transfer, (x) each person to which any of such Securities or any interest in any of such Securities is or may be transferred (a) shall have executed and delivered to Parent and Sub a counterpart to this Agreement pursuant to which such person shall be bound by all of the terms and provisions of this Agreement, and (b) shall have agreed in writing with Parent and Sub to hold such Securities or interest in such Securities subject to all of the terms and provisions of this Agreement, and (y) this Agreement shall be the legal, valid and binding agreement of such person, enforceable against such person in accordance with its terms.

1.2 No Solicitation. Between the date hereof and the Termination Date, except as permitted by Section 5.2 of the Merger Agreement, the Stockholder shall not and shall not authorize any agent, representative, affiliate, advisor, attorney, accountant or associate of Stockholder (collectively, “Representatives”) to, directly or indirectly, take any action that the Company is prohibited from taking under Section 5.2 of the Merger Agreement.

1.3 Certain Events. This Agreement and the obligations hereunder will attach to the Securities and will be binding upon any person to which legal or beneficial ownership of any or all of the Securities passes, whether by operation of Law or otherwise, including without limitation, the Stockholder’s successors or assigns. This Agreement and the obligations hereunder will also attach to any additional Shares or other Securities of the Company issued to or acquired by the Stockholder.

1.4 Grant of Proxy; Voting Agreement.

(a) The Stockholder has revoked or terminated any proxies, voting agreements or similar arrangements previously given or entered into with respect to the Securities and hereby irrevocably appoints Parent as proxy for Stockholder to vote the Securities for Stockholder and in Stockholder’s name, place and stead, at any annual or special meeting, or at any adjournment thereof or pursuant to any consent of the stockholders of the Company, in lieu of a meeting or otherwise, whether before or after the Acceptance Time (as defined in the Merger Agreement), for the adoption of the Merger Agreement. Parent acknowledges that the proxy granted hereby shall not be effective for any other purpose other than that specified in the previous sentence. The parties acknowledge and agree that neither Parent, nor Parent’s successors, assigns, subsidiaries, divisions, employees, officers, directors, stockholders, agents and affiliates shall owe any duty to, whether in law or otherwise, or incur any liability of any kind whatsoever, including without limitation, with respect to any and all claims, losses, demands, causes of action, costs, expenses (including reasonable attorney’s fees) and compensation of any kind or nature whatsoever to the Stockholder in connection with or as a result of any voting by Parent of the Securities or any execution of any consent. The parties acknowledge that, pursuant to the authority hereby granted under the irrevocable proxy, Parent may vote the Securities in furtherance of its own interests, and Parent is not acting as a fiduciary for the Stockholder.

Annex II - 2

(b) Notwithstanding the foregoing grant to Parent of the irrevocable proxy, if Parent elects not to exercise its rights to vote the Securities pursuant to the irrevocable proxy, Stockholder agrees to vote the Securities during the term of this Agreement in favor of or give its consent to, as applicable, a proposal to adopt the Merger Agreement as described in Section 1.4 at any annual or special meeting or action of the stockholders of the Company in lieu of a meeting or otherwise.

(c) This irrevocable proxy shall not be terminated by any act of the Stockholder or by operation of law, whether by the death or incapacity of the Stockholder or by the occurrence of any other event or events (including, without limiting the foregoing, the termination of any trust or estate for which Stockholder is acting as a fiduciary or fiduciaries or the dissolution or liquidation of any corporation or partnership). If between the execution hereof and the Termination Date, Stockholder should die or become incapacitated, or if any trust or estate holding the Securities should be terminated, or if any corporation or partnership holding the Securities should be dissolved or liquidated, or if any other such similar event or events shall occur before the Termination Date, certificates representing the Securities shall be delivered by or on behalf of Stockholder in accordance with the terms and conditions of the Merger Agreement and this Agreement, and actions taken by Parent hereunder shall be as valid as if such death, incapacity, termination, dissolution, liquidation or other similar event or events had not occurred, regardless of whether or not Parent has received notice of such death, incapacity, termination, dissolution, liquidation or other event.

1.5 Tender of Securities. Stockholder agrees, in exchange for the consideration described in the Merger Agreement, to tender the Shares beneficially owned as of the date hereof and set forth on Schedule I hereto for which Stockholder has sole dispositive power to Sub in the Offer as soon as practicable following the commencement of the Offer, and in any event not later than five (5) business days following the commencement of the Offer, and Stockholder shall not withdraw any such Shares so tendered unless the Offer is terminated; provided, however, that Stockholder shall have no duty or obligation to tender any Shares into the Offer if such action would cause Stockholder to incur liability under Section 16(b) of the Exchange Act.

1.6 Option.

(a) On the terms and subject to the conditions set forth herein, Stockholder hereby grants to Parent an irrevocable option (the “Option”) to purchase all of the right, title and interest of Stockholder in and to Stockholder’s Securities with a price per share equal to the Offer Price; provided, however, that Stockholder shall have no duty or obligation to sell any Securities to Parent if such action would cause Stockholder to incur liability under Section 16(b) of the Exchange Act. Parent may exercise the Option in whole, but not in part, if, but only if, (i) Sub has acquired Shares pursuant to the Offer and (ii) Stockholder has failed to tender into the Offer any Shares or shall have withdrawn the tender of any Shares into the Offer in breach of this Agreement. Parent may exercise the Option at any time within the sixty (60) days following the date when such Option first becomes exercisable.

(b) In the event that Parent is entitled to and wishes to exercise the Option, Parent shall send a written notice to Stockholder specifying the place and the date for the

Annex II - 3

closing of such purchase, which date shall be not more than sixty (60) days after the date of such notice; provided that in the event that prior notification to, or approval of, any Governmental Entity is required in connection with the exercise of the Option or there shall be in effect any preliminary or final injunction or other order issued by any Governmental Entity prohibiting the exercise of the Option, the period of time during which the date of the closing may be fixed shall be extended until the tenth (10th) day following the last date on which all required approvals shall have been obtained, all required waiting periods shall have expired or been terminated and any such prohibition shall have been vacated, terminated or waived.

2. CONTINGENT PAYMENT RIGHTS

2.1. CPRs. The CPRs represent the rights of Holders to receive contingent cash payments pursuant to this Agreement. The initial Holders will be determined pursuant to the terms of the Merger Agreement.

2.2. Nontransferable. The CPRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer.

2.3. No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CPRs will not be evidenced by a certificate or other instrument.

(b) The Rights Agent will keep a register (the “CPR Register”) for the purpose of registering CPRs and transfers of CPRs as herein provided. The CPR Register will initially show one position for Cede & Co representing all the shares of Company Common Stock held by DTC on behalf of the street holders of the shares of Company Common Stock tendered by such holders in the Offer or held by such holders as of immediately prior to the Effective Time. The Rights Agent will have

Annex IV - 6

no responsibility whatsoever directly to the street name holders with respect to transfers of CPRs. With respect to any payments to be made under Section 2.4 below, the Rights Agent will accomplish the payment to any former street name holders of shares of Company Common Stock by sending one lump payment to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CPR must be in writing and accompanied by a written instrument of transfer in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative or the Holder’s survivor, and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice, the Rights Agent will, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the CPRs in the CPR Register. No service charge shall be made for any registration of transfer of a CPR, but Parent and Rights Agent may require payment of a sum sufficient to cover any stamp or other tax or governmental charge that is imposed in connection with any such registration of transfer. The Rights Agent shall have no duty or obligation to take any action under any section of this Agreement that requires the payment by a Holder of a CPR of applicable taxes or charges unless and until the Rights Agent is satisfied that all such taxes or charges have been paid. All duly transferred CPRs registered in the CPR Register will be the valid obligations of Parent and will entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CPR will be valid until registered in the CPR Register.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CPR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent will, subject to its reasonable determination that the transfer instrument is in proper form, promptly record the change of address in the CPR Register.

2.4. Payment Procedures.

(a) On or before the fifth Business Day following (i) any EMA Payment Trigger Date and (ii) July 1, 2019, Parent will deliver to the Rights Agent a notice (the “EMA Approval Payment Notice”) indicating whether EMA Approval was achieved, and if achieved, whether EMA Preferred Product Label Approval was achieved. On or before the fifth Business Day following (i) any FDA Payment Trigger Date and (ii) July 1, 2019, Parent will deliver to the Rights Agent a notice (the “FDA Approval Payment Notice”) indicating whether FDA Product Approval was achieved, and if achieved, whether FDA Preferred Product Label Approval was achieved. On or before the fifth Business Day following (i) any Sales Milestone Trigger Date and (ii) July 1, 2024, unless prior to such date one or more Regulatory Approval Payment Notices was delivered to the Rights Agent indicating both FDA Preferred Product Label Approval and EMA Preferred Product Label Approval had been achieved, Parent will deliver to the Rights Agent a notice (the “Milestone Notice”) indicating whether a Sales Milestone was achieved.

(b) The Rights Agent will, within ten Business Days of receipt of any Regulatory Approval Payment Notice (each such date, a “Regulatory Approval Payment Date”), send each Holder at its registered address a copy of the Regulatory Approval Payment Notice. If a Regulatory Approval Payment Amount is payable to the Holders, then at the time the Rights Agent sends a copy of a Regulatory Approval Payment Notice to the Holders, the Rights Agent will also pay the applicable Regulatory Approval Payment Amount, as calculated by Parent and communicated to Rights Agent, to each of the Holders (the amount to which each Holder is entitled to receive will be the

Annex IV - 7

applicable Regulatory Approval Payment Amount multiplied by the number of CPRs held by such Holder as reflected on the CPR Register) by check mailed to the address of each Holder as reflected in the CPR Register as of the close of business on the last Business Day prior to such Regulatory Approval Payment Date.

(c) The Rights Agent will, within ten Business Days of receipt of any Milestone Notice, send each Holder at its registered address a copy of the Milestone Notice. If a Milestone Payment Amount is payable to the Holders, then at the time the Rights Agent sends a copy of a Milestone Notice to the Holders, the Rights Agent will also pay the applicable Milestone Payment Amount, as calculated by Parent and communicated to Rights Agent, to each of the Holders (the amount to which each Holder is entitled to receive will be the applicable Milestone Payment Amount multiplied by the number of CPRs held by such Holder as reflected on the CPR Register) by check mailed to the address of each Holder as reflected in the CPR Register as of the close of business on the last Business Day prior to such Milestone Payment Date.

(d) Parent shall be entitled to deduct or withhold, or cause the Rights Agent to deduct or withhold, from any Payment Amount otherwise payable pursuant to this Agreement such amounts as may be required to be deducted or withheld therefrom under the Code, the Treasury Regulations thereunder, or any other applicable Tax Law, as may be determined by Parent or the Rights Agent. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid, and as soon as practicable after any payment of such taxes by Parent or the Rights Agent, Parent shall deliver (or shall cause the Rights Agent to deliver) to the person to whom such amounts would otherwise have been paid the original or a certified copy of a receipt issued by the applicable taxing authority evidencing such payment, a copy of the return reporting such payment, or other reasonably acceptable evidence of such payment.

(e) Any portion of any Payment Amount that remains undistributed to the Holders six (6) months after an applicable Payment Date will be delivered by the Rights Agent to Parent, upon demand, and any Holder will thereafter look only to Parent for payment of such Payment Amount, without interest, but such Holder will have no greater rights against Parent than those accorded to general unsecured creditors of Parent under applicable law.

(f) Neither Parent nor the Rights Agent will be liable to any person in respect of any Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Payment Amount has not been paid immediately prior to the date on which such Payment Amount would otherwise escheat to or become the property of any Governmental Entity, any such Payment Amount will, to the extent permitted by applicable law, become the property of Parent, free and clear of all claims or interest of any person previously entitled thereto. In addition to and not in limitation of any other indemnity obligation herein, Parent agrees to indemnify and hold harmless Rights Agent with respect to any liability, penalty, cost or expense Rights Agent may incur or be subject to in connection with transferring such property to Parent.

2.5. No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent.

(a) The CPRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable on the CPRs to any Holder.

(b) The CPRs will not represent any equity or ownership interest in Parent or in any constituent company to the Merger.

Annex IV - 8

3.2. Certain Rights of Rights Agent. The Rights Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied covenants or obligations will be read into this Agreement against the Rights Agent. In addition:

(a) the Rights Agent may rely and will be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) whenever the Rights Agent will deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Rights Agent may rely upon an Officer’s Certificate, which certificate shall be full authorization and protection to the Rights Agent, and the Rights Agent shall, in the absence of bad faith, gross negligence or willful misconduct on its part, incur no liability for or in respect of any action taken, suffered or omitted to be taken by it under the provisions of this Agreement in reliance upon such certificate;

(c) the Rights Agent may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of counsel will be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(d) the permissive rights of the Rights Agent to do things enumerated in this Agreement will not be construed as a duty;

(e) the Rights Agent will not be required to give any note or surety in respect of the execution of such powers or otherwise in respect of the premises;

(f) the Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Parent only;

(g) the Rights Agent will have no liability in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution and delivery hereof by the Rights Agent); nor shall it be responsible for any breach by the Parent of any covenant or condition contained in this Agreement;

(h) Parent agrees to indemnify Rights Agent for, and hold Rights Agent harmless against, any loss, liability, claim, demands, suits or expense arising out of or in connection with Rights Agent’s duties under this Agreement, including the costs and expenses of defending Rights Agent against any claims, charges, demands, suits or loss, unless such loss has been determined by a court of competent jurisdiction to be a result of Rights Agent’s gross negligence, bad faith or willful or intentional misconduct;

(i) Rights Agent shall not be liable for consequential damages under any provision of this Agreement or for any consequential damages arising out of any act or failure to act hereunder in the absence of bad faith, gross negligence or willful misconduct on its part;

(j) Parent agrees (i) to pay the fees and expenses of the Rights Agent in connection with this Agreement as agreed upon in writing by Rights Agent and Parent on or prior to the date hereof, and (ii) to reimburse the Rights Agent for all taxes and governmental charges, reasonable expenses and other charges of any kind and nature incurred by the Rights Agent in the execution of this Agreement (other than taxes imposed on or measured by the Rights Agent’s net income and

Annex IV - 9

franchise or similar taxes imposed on it (in lieu of net income taxes)). The Rights Agent will also be entitled to reimbursement from Parent for all reasonable and necessary out-of-pocket expenses paid or incurred by it in connection with the administration by the Rights Agent of its duties hereunder; and

(k) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

3.3. Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent specifying a date when such resignation will take effect, which notice will be sent at least 60 days prior to the date so specified but in no event will such resignation become effective until a successor Rights Agent has been appointed. Parent has the right to remove Rights Agent at any time by a Board Resolution specifying a date when such removal will take effect but no such removal will become effective until a successor Rights Agent has been appointed. Notice of such removal will be given by Parent to Rights Agent, which notice will be sent at least 60 days prior to the date so specified.

(b) If the Rights Agent provides notice of its intent to resign, is removed or becomes incapable of acting, Parent, by a Board Resolution, will as soon as is reasonably possible appoint a qualified successor Rights Agent who may be a Holder but may not be an officer of Parent. The successor Rights Agent so appointed will, forthwith upon its acceptance of such appointment in accordance with Section 3.4, become the successor Rights Agent.

(c) Parent will give notice of each resignation and each removal of a Rights Agent and each appointment of a successor Rights Agent by mailing written notice of such event by first-class mail to the Holders as their names and addresses appear in the CPR Register. Each notice will include the name and address of the successor Rights Agent. If Parent fails to send such notice within ten days after acceptance of appointment by a successor Rights Agent, the successor Rights Agent will cause the notice to be mailed at the expense of Parent.

3.4. Acceptance of Appointment by Successor. Every successor Rights Agent appointed hereunder will execute, acknowledge and deliver to Parent and to the retiring Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and thereupon such successor Rights Agent, without any further act, deed or conveyance, will become vested with all the rights, powers, trusts and duties of the retiring Rights Agent. On request of Parent or the successor Rights Agent, the retiring Rights Agent will execute and deliver an instrument transferring to the successor Rights Agent all the rights, powers and trusts of the retiring Rights Agent.

4. COVENANTS

4.3. Milestones. Parent shall, and shall cause its controlled Affiliates to, use Diligent Efforts to achieve each of the Milestones.

Annex IV - 10

4.4. Books and Records. Parent shall, and shall cause its Subsidiaries to, keep true, complete and accurate records in sufficient detail to enable the Holders and their consultants or professional advisors to determine the amounts payable hereunder.

4.5. Audits.

(a) Upon the written request of the Acting Holders within one (1) year of the delivery of any Milestone Notice (the “Review Request Period”) but no more than once per Milestone Notice, Parent shall permit, and shall cause its controlled Affiliates to permit, the Independent Accountant to have access during normal business hours to such of the records of the Company as may be reasonably necessary to verify the accuracy of the Net Sales Statement and the figures underlying the calculations set forth therein, including, without limitation, all written materials related to any sale transaction reasonably requested by such Independent Accountant. The Independent Accountant shall be charged to come to a final determination with respect to those specific items in the Net Sales Statement that the parties disagree on and submit to it for resolution. All other items in the Net Sales Statement that the parties do not submit, prior to the end of the Review Request Period, to the Independent Accountant for resolution shall be deemed to be agreed by the parties and the Independent Accountant shall not be charged with calculating or validating those agreed upon items. If issues are submitted to the Independent Accountant for resolution, Parent shall, and shall cause to its controlled Affiliates to, furnish to the Independent Accountant such access, work papers and other documents and information related to those disputed issues as the Independent Accountant may request and as are available to Parent. The Independent Accountant shall disclose to Parent and the Acting Holders any matters directly related to their findings to the extent necessary to verify the accuracy or completeness of the Net Sales Statements. The fees charged by such accounting firm shall be paid by Parent.

(b) If the Independent Accountant concludes that either the Four Hundred Million Dollar Sales Target or the Eight Hundred Million Dollar Sales Target was achieved and a Milestone Payment Amount that was properly due was not paid to the Holders (the difference in payment being the “CPR Shortfall”), Parent shall pay the CPR Shortfall with respect to each CPR within ten (10) days of the date the Acting Holders deliver to Parent the Independent Accountant’s written report. The decision of the Independent Accountant shall be final, conclusive and binding on Parent and the Holders, shall be non-appealable and shall not be subject to further review.

(c) If, upon the expiration of the Review Request Period, the Acting Holders have not requested a review of the Net Sales Statement in accordance with this Section 4.5, the calculations set forth in the Net Sales Statement shall be binding and conclusive upon the Holders.

(d) Each person seeking to receive information from Parent in connection with a review pursuant to this Section 4.5 shall enter into, and shall cause its accounting firm to enter into, a reasonable and mutually satisfactory confidentiality agreement with Parent or any controlled Affiliate obligating such party to retain all such information disclosed to such party in confidence pursuant to such confidentiality agreement.

Where this Agreement provides for notice to Holders, such notice will 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 CPR Register, not later than the latest date, and not earlier than the earliest date, if any, 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 will affect the sufficiency of such notice with respect to other Holders.

6.3. Parent Successors and Assigns. Parent may assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more direct or indirect wholly-owned subsidiaries of Parent or to any purchaser or licensee of substantial rights to the Product (each, an “Assignee”). Any such Assignee may thereafter assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more additional Assignees; provided, however, that in connection with any assignment to an Assignee, Parent and Sub (or the other assignor) shall agree to remain liable for the performance by Parent and Sub (and such other assignor, if applicable) of their obligations hereunder. This Agreement will be binding upon, inure to the benefit of and be enforceable by Parent’s successors and each Assignee, and this Agreement shall not restrict Parent’s, any Assignee’s or any of their respective successor’s ability to merge or consolidate. Each of Parent’s successors shall expressly assume by an instrument supplemental hereto, executed and delivered to the Rights Agent, the due and punctual payment of the CPRs and the due and punctual performance and observance of all of the covenants and obligations of this Agreement to be performed or observed by Parent.

6.4. Benefits of Agreement. Nothing in this Agreement, express or implied, will give to any Person (other than the Rights Agent, Parent, Parent’s successors and assignees, and the Holders) any benefit or any legal or equitable right, remedy or claim under this Agreement or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the, Rights Agent, Parent, Parent’s successors and assignees, and the Holders. The rights of Holders are limited to those expressly provided in this Agreement and the Merger Agreement.

6.5. Governing Law. This Agreement, the CPRs and all actions arising under or in connection therewith shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof, provided, however, that the laws of the respective jurisdictions of incorporation of each of the parties shall govern the relative rights, obligations, powers, duties and other internal affairs of such party and its board of directors.

6.6. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable. The parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

6.7. Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by facsimile or by an electronic scan delivered by electronic mail), each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other party, it being understood that the parties need not sign the same counterpart.

6.8. Termination. This Agreement will be terminated and of no force or effect, the parties hereto will have no liability hereunder (other than with respect to monies due and owing by Parent to Rights Agent), and no payments will be required to be made, upon the earlier to occur of (a) the mailing by

Annex IV - 14

the Rights Agent to the address of each Holder as reflected in the CPR Register the full amount of all potential Payment Amounts required to be paid under the terms of this Agreement and (b) the expiration of the final Review Request Period, unless there is an ongoing audit pursuant to Section 4.5, in which case until such audit has been completed. In no event will any Regulatory Approval Payment Amount become payable after the Regulatory Approval Payment Target Date, nor will any Milestone Payment Amount become payable on account of sales of the Product consummated after June 30, 2024.

6.9. Entire Agreement. This Agreement and the Merger Agreement (including the schedules, annexes and exhibits thereto and the documents and instruments referred to therein) contain the entire understanding of the parties hereto and thereto with reference to the transactions and matters contemplated hereby and thereby and supersedes all prior agreements, written or oral, among the parties with respect hereto and thereto. If and to the extent that any provision of this Agreement is inconsistent or conflicts with the Merger Agreement, this Agreement will govern and be controlling.

6.10. Dispute Resolution. Any dispute arising out of or relating to this contract, including the breach, termination or validity thereof, shall be finally resolved by arbitration in accordance with the International Institute for Conflict Prevention and Resolution Rules for Non-Administered Arbitration by three arbitrators, of whom each party shall designate one in accordance with the ‘screened’ appointment procedure provided in Rule 5.4. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1 et seq., and judgment upon the award rendered by the arbitrator(s) may be entered by any court having jurisdiction thereof. The place of the arbitration shall be New York, New York. In any such dispute, actions on behalf of Holders, including initiation of arbitration, shall be approved by the Acting Holders.
