THE OFFER AND THE MERGER

Section 2.01. The Offer.

(a) Commencement of the Offer. Provided that this Agreement shall not have been terminated in accordance with Section 8.01, as promptly as practicable but in no event later than fifteen (15) Business Days after the date of this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, commence (within the meaning of Rule 14d-2 promulgated by the SEC under the Exchange Act) the Offer to purchase any and all of the Shares at a price per Share equal to the Per Share Amount to the holder of the Share in cash, net of applicable withholding taxes and without interest.

(b) Terms and Conditions of the Offer. The obligations of Merger Sub to, and of Parent to cause Merger Sub to, accept for payment, and pay for, any Shares tendered pursuant to the Offer are subject to the terms and conditions of this Agreement and the prior satisfaction or waiver of the Minimum Tender Condition, the Termination Condition and the other conditions set forth in Annex A (collectively, the “Offer Conditions”). Merger Sub expressly reserves the right (but is not obligated to) at any time and from time to time in its sole discretion to waive, in whole or in part, any Offer Condition or modify the terms of the Offer (including by increasing the Per Share Amount), in each case only in a manner not inconsistent with the terms of this Agreement, except that, without the prior written consent of the Company, Merger Sub shall not (i) reduce the number of Shares subject to the Offer, (ii) reduce the Per Share Amount, (iii) amend, modify or waive the Minimum Tender Condition or the Termination Condition, (iv) add to the Offer Conditions or amend, modify or supplement any Offer Condition or any other term of the Offer in any manner adverse to the holders of Shares or that would, individually or in the aggregate, reasonably be expected to prevent or materially delay the consummation of the Offer or the Merger or impair the ability of Parent or Merger Sub to consummate the Offer, (v) extend or otherwise change the Offer Expiration Time (except as required or permitted by the other provisions of this Section 2.01), (vi) change the form of consideration payable in the Offer or (vii) provide for any “subsequent offering period” (or any extension thereof) within the meaning of Rule 14d-11 under the Exchange Act.

(c) Expiration and Extension of the Offer. The expiration date and time for the Offer, as the same may be extended from time to time, is hereinafter referred to as the “Offer Expiration Time.” The initial Offer Expiration Time shall be 11:59 p.m. (New York City time) on the twentieth (20th) Business Day following (and including the day of) commencement of the Offer (determined pursuant to Exchange Act Rule 14d-1(g)(3)). Subject to the parties’ respective rights to terminate the Agreement pursuant to Section 8.01 and notwithstanding anything to the contrary in this Agreement, Merger Sub shall (and Parent shall cause Merger Sub to):

(i) extend the Offer for any period required by any applicable rule, regulation, interpretation or position of the SEC or the staff thereof or Nasdaq (including in order to comply with Exchange Act Rule 14e-1(b) in respect of any change in the Per Share Amount) or as may be necessary to resolve any comments of the SEC or the staff or Nasdaq, in each case, as applicable to the Offer, the Schedule 14D-9 or the Offer Documents; and

(ii) if, as of any then-scheduled Offer Expiration Time, any Offer Condition is not satisfied and has not been waived by Parent or Merger Sub (to the extent permitted hereunder), extend the Offer on one or more occasions in consecutive increments of up to ten (10) Business Days each (or such longer or shorter period as the parties hereto may agree) in order to permit the satisfaction of such Offer Conditions;

provided, that, without the Company’s written consent, Merger Sub shall not extend the Offer, and without Parent’s prior written consent, Merger Sub shall not be required to extend the Offer, in each case beyond the earlier of the End Date or the valid termination of this Agreement in accordance with Section 8.01.

(d) Consummation of the Offer; Payment. On the terms and subject to the conditions of the Offer and this Agreement, Merger Sub shall (and Parent shall cause Merger Sub to) (i) consummate the Offer and accept for payment all Shares validly tendered and not withdrawn pursuant to the Offer promptly after (in any event, no later than the first (1st) Business Day after) the Offer Expiration Time and (ii) promptly after (in any event, no more than three (3) Business Days after) the Offer Expiration Time, pay (subject to any applicable withholding tax) for such Shares. Parent shall provide or cause to be provided to Merger Sub on a timely basis the funds necessary to purchase any Shares that Merger Sub becomes obligated to purchase pursuant to the Offer. The Per Share Amount shall be paid to the holder of the Share in cash, net of applicable withholding taxes and without interest, upon the terms and subject to the conditions of the Offer.

(e) Termination of the Offer. Parent and Merger Sub may not terminate the Offer prior to the Offer Expiration Time (as it may be extended and re-extended in accordance with this Agreement), unless and until this Agreement is validly terminated in accordance with Section 8.01. In the event that this Agreement is validly terminated pursuant to Section 8.01, prior to any scheduled expiration thereof, Merger Sub shall, and Parent shall cause Merger Sub to, promptly (and in any event within two (2) Business Days of such termination) irrevocably and unconditionally terminate the Offer. If the Offer is terminated or withdrawn by Merger Sub, Merger Sub shall promptly return, and shall cause any depository acting on behalf of Merger Sub to return, all tendered Shares to the registered holders thereof in accordance with Applicable Law.

(f) Offer Documents. On the date of commencement of the Offer (determined pursuant to Exchange Act Rule 14d-2), Parent and Merger Sub shall (i) file with the SEC, in accordance with Exchange Act Rule 14d-3, a Tender Offer Statement on Schedule TO with respect to the Offer, which Tender Offer Statement shall contain an offer to purchase and a related letter of transmittal, summary advertisement, notice of guaranteed delivery and other ancillary offer documents pursuant to which the Offer will be made (such Schedule TO and documents, together with any supplements or amendments thereto, the “Offer Documents”) and (ii) cause the Offer Documents to be disseminated to holders of Shares, in each case as and to the extent required by Applicable Law. The Company shall promptly furnish Parent and Merger Sub with all information concerning the Company and its stockholders required by the Exchange Act or other Applicable Law to be set forth in the Offer Documents and all other information concerning the Company and its stockholders as reasonably requested by Parent and Merger Sub for inclusion in the Offer Documents and, unless previously withdrawn in accordance with Section 6.02(d) or Section 6.02(e), shall allow Parent and Merger Sub to include the Board Recommendation in the Offer Documents. Parent and Merger Sub shall cause the Offer Documents to comply in all material respects with the requirements of Applicable Law and, on the date first filed with the SEC and on the date first published, sent or given to the holders of Shares, not to 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 therein, in light of the circumstances under which they were made, not misleading, except that no covenant is made by Parent or Merger Sub with respect to information supplied by the Company for inclusion or incorporation by reference in the Offer Documents. Each of Parent, Merger Sub and the Company shall promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information is or shall have become false or misleading in any

material respect, and each of Parent and Merger Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and disseminated to the holders of Shares, in each case as and to the extent required by Applicable Law. The Company and its counsel shall be given a reasonable opportunity to review and comment upon the Offer Documents and any amendments and supplements thereto prior to filing such documents with the SEC or dissemination of such documents to the stockholders of the Company and Parent and Merger Sub shall give reasonable and good faith consideration to any comments made by the Company and its counsel. Parent and Merger Sub shall (i) provide the Company and its counsel any written comments that Parent, Merger Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments (and shall give the Company and its counsel prompt telephonic notice of any material discussions with or oral comments received from the SEC staff), (ii) provide the Company and its counsel a reasonable opportunity to review and comment upon the proposed responses to any such comments and a copy of any proposed written responses thereto prior to the filing thereof, and (iii) give reasonable and good faith consideration to any comments made by the Company and its counsel on any such proposed responses. Parent and Merger Sub shall respond promptly to any comments of the SEC or its staff with respect to the Offer Documents.

(g) Guaranteed Delivery. For purposes of this Agreement and the Offer, unless mutually agreed by Parent and the Company, any Shares subject to notices of guaranteed delivery shall be deemed not to be validly tendered into the Offer unless and until the Shares underlying such notices of guaranteed delivery are “received” (as defined by Section 251(h) of the DGCL) by Merger Sub or by an agent of Merger Sub.

Section 2.02. Company Actions.

(a) Approval. The Company hereby approves of and consents to the Transactions. The Company agrees that no shares of Company Common Stock held by the Company or any of the Company Subsidiaries (other than any such shares held on behalf of third parties) will be tendered pursuant to the Offer.

(b) Schedule 14D-9. On the date the Offer Documents are filed with the SEC, as soon as reasonably practicable following the filing of the Schedule TO, the Company shall (i) file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended or supplemented from time to time and including any exhibits thereto, the “Schedule 14D-9”), including the Board Recommendation (subject to the Board Recommendation not having been withdrawn or modified in accordance with Section 6.02(d) or Section 6.02(e)), and a notice of appraisal rights and (ii) cause the Schedule 14D-9 to be disseminated to holders of Shares as and to the extent required by Rule 14d-9 promulgated under the Exchange Act and any other Applicable Law, including by setting the Stockholder List Date as the record date for purposes of receiving the notice required by Section 262(d)(2) of the DGCL. Parent and Merger Sub shall promptly furnish the Company with all information concerning Parent and Merger Sub required by the Exchange Act to be set forth in the Schedule 14D-9, and all other information concerning Parent and Merger Sub as reasonably requested by the Company for inclusion in the Schedule 14D-9.

The Merger shall be governed by and effected pursuant to Section 251(h) of the DGCL.

(b) Effective Time.

(c) Surviving Corporation. At the Effective Time, Merger Sub shall be merged with and into the Company in accordance with the DGCL, including Section 251(h) thereof, whereupon the separate existence of Merger Sub shall cease, and the Company shall be the surviving corporation in the Merger (the “Surviving Corporation”) and shall become a wholly-owned Subsidiary of Parent, and the separate corporate existence of the Company, with all its rights, privileges, immunities, powers and franchises, shall continue unaffected by the Merger. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all of the properties, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

(d) Effects of the Merger. The Merger shall have the effects set forth in the applicable provisions of the DGCL, this Agreement and the Certificate of Merger.

Section 2.05. Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the stockholders thereof or any other Person:

(a) except as otherwise provided in Section 2.05(b), Section 2.05(c), Section 2.05(d) or Section 2.07, each Share outstanding immediately prior to the Effective Time shall (i) be converted automatically into the right to receive the Per Share Amount in cash, net of applicable withholding taxes and without interest and (ii) cease to be outstanding and shall automatically be cancelled and cease to exist and each holder of a Certificate representing any such Shares shall have only the right to receive the Per Share Amount with respect thereto in accordance with Section 2.06;

(b) each Share owned by Parent, Merger Sub or any other direct or indirect wholly-owned subsidiary of Parent immediately prior to the Effective Time (other than Shares tendered and accepted for payment by Merger Sub in connection with the Offer) shall be cancelled and cease to exist, and no payment shall be made with respect thereto and each holder of a Certificate representing any such Shares shall cease to have any rights with respect thereto;

(c) each Share owned by the Company or held in the Company’s treasury immediately prior to the Effective Time shall be cancelled and cease to exist, and no payment shall be made with respect thereto and each holder of a Certificate representing any such Shares shall cease to have any rights with respect thereto;

(d) each Share owned by any direct or indirect wholly-owned Subsidiary of the Company immediately prior to the Effective Time shall be converted automatically into such number of fully paid, nonassessable shares of common stock, par value $0.001 per share, of the Surviving Corporation (the “Surviving Corporation Common Stock”) such that each direct or indirect wholly owned Subsidiary that owned capital stock in the Company immediately prior to the Effective Time shall own the same percentage of the outstanding capital stock of the Surviving Corporation immediately following the Effective Time, without any payment of consideration therefor; and

(e) each share of common stock of Merger Sub outstanding immediately prior to the Effective Time shall be converted into and become one fully paid, nonassessable share of Surviving Corporation Common Stock, which, together with any shares of Surviving Corporation Common Stock held by any direct or indirect wholly-owned Subsidiary of the Surviving Corporation pursuant to Section 2.05(d), shall constitute the only outstanding shares of capital stock of the Surviving Corporation as of immediately following the Effective Time.

Section 2.06. Surrender and Payment.

(a) Paying Agent and Payment Fund. Prior to the expiration of the Offer, Parent shall appoint a paying agent reasonably acceptable to the Company (the “Paying Agent”) for the purpose of paying the Per Share Amount to each holder of a Share outstanding immediately prior to the Effective Time in accordance with this Section 2.06. As promptly as practicable after the Effective Time, Parent shall, or shall take all steps necessary to enable and

cause the Surviving Corporation to, deposit with the Paying Agent, for the benefit of the holders of Shares outstanding immediately prior to the Effective Time, the cash necessary to pay for the Shares that are converted into the right to receive the Per Share Amount in the Merger pursuant to Section 2.05(a) (the “Payment Fund”). To the extent such fund diminishes for any reason below the level required to make prompt payment of any outstanding Per Share Amounts to be paid in exchange for Shares converted in the Merger pursuant to Section 2.05(a), Parent and the Surviving Corporation shall promptly replace or restore the lost portion of such fund so as to ensure that it is, at all times, maintained at a level sufficient to make such payments. The Payment Fund shall be invested by the Paying Agent as directed by the Surviving Corporation; provided, that such investments shall be in obligations of or guaranteed by the United States of America in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion, or in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition or a combination of the foregoing and, in any such case, no such instrument shall have a maturity exceeding three (3) months. Promptly after the Effective Time and in any event no later than five (5) Business Days after the Effective Time, Parent shall send, or shall cause the Paying Agent to send, to each record holder of Shares at the Effective Time, in each case whose Shares were converted into the right to receive the Per Share Amount pursuant to Section 2.05(a), a letter of transmittal and instructions (which shall specify that delivery of the Shares shall be effected, and risk of loss and title shall pass, only upon proper delivery or transfer of the certificate representing the Shares (the “Certificates”; provided, however, that any references herein to “Certificates” are deemed to include references to effective affidavits of loss in accordance with Section 2.12 or to book-entry account statements relating to the ownership of Shares, as applicable) to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify (after due consultation with the Company) prior to the consummation of the Offer) for use in effecting the surrender of Certificates in exchange for payment of the Per Share Amount for each Share.

(b) Surrender of Shares. Each holder of Shares that have been converted into the right to receive the Per Share Amount shall be entitled to receive the Per Share Amount in respect of the Shares represented by a Certificate promptly upon (i) surrender to the Paying Agent of the Certificate (provided, however, that delivery of a book-entry statement shall not be required in respect of any uncertificated Shares held of record in book-entry), together with a duly completed and validly executed letter of transmittal and such other documents as may reasonably be requested by the Paying Agent, or (ii) receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of the exchange of book-entry Shares. Until so surrendered or transferred each such Certificate shall represent after the Effective Time for all purposes only the right to receive such Per Share Amount. No interest shall be paid or accrued on the cash payable upon the surrender or transfer of such Certificate.

(c) Unregistered Transferees. If any portion of the aggregate Per Share Amounts to be paid in respect of any Certificate is to be paid to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer and (ii) the Person requesting such payment shall either pay to the Paying

Promptly following the execution of this Agreement, on the date hereof, the Acquired

Companies shall, and shall direct their respective Representatives to, (A) cease and cause to be terminated any solicitation and any and all existing discussions or negotiations with any Person conducted heretofore with respect to any Acquisition Proposal or any inquiry or request for information that could reasonably be expected to lead to, or result in, an Acquisition Proposal and (B) terminate access by any Third Party to any physical or electronic data room relating to any potential Acquisition Transaction. Within three (3) Business Days of the execution of this Agreement, the Company shall request the prompt return or destruction of any confidential information provided to any such Third Party or any of its Representatives and from any other Person to whom confidential information was provided since the Distribution Date in connection with a proposed Acquisition Transaction. Notwithstanding anything herein to the contrary, the Company shall be permitted to grant waivers of, and not enforce, any standstill provision or similar provision that has the effect of prohibiting the counterparty thereto from making an Acquisition Proposal to the Company Board.

(b) Notwithstanding anything to the contrary contained in this Agreement, if prior to the consummation of the Offer the Company receives a bona fide written Acquisition Proposal (which Acquisition Proposal was made after the date of this Agreement and did not result from a breach of this Section 6.02 in any material respect), and the Company Board determines in good faith, after consultation with its financial advisors and outside legal counsel, that such Acquisition Proposal constitutes, or could reasonably be expected to lead to, a Superior Proposal, then the Company and its Representatives may, subject to compliance with this Section 6.02, do any or all of the following: (i) furnish any information with respect to the Company and its Subsidiaries and access thereto to any Third Party making such Acquisition Proposal; provided, that (A) prior to furnishing any such information, the Company receives from such Third Party an executed Acceptable Confidentiality Agreement and (B) any such non-public information so furnished has been previously provided or made available to Parent or is provided or made available (including through the Data Room) to Parent promptly (and in any event no later than twenty-four (24) hours) after it is so furnished to such Third Party or (ii) participate or engage in negotiations or discussions with the Person making such Acquisition Proposal and its Representatives regarding such Acquisition Proposal. The Company acknowledges and agrees that any action that if taken by the Company would be a breach of the provisions set forth in this Section 6.02, is taken by (x) a director or officer of the Company or (y) investment bankers or financial advisors retained by the Company, such action shall be deemed to constitute a breach of this Section 6.02 by the Company.

(c) Except as set forth in this Section 6.02, neither the Company Board nor any committee thereof shall (i) (A) fail to make, withhold or withdraw (or modify, amend or qualify in a manner adverse to Parent or Merger Sub), or propose publicly to withhold or withdraw (or modify, amend or qualify in a manner adverse to Parent or Merger Sub), the Board Recommendation (it being understood that failing to recommend the rejection of any Acquisition Proposal that is a tender offer or exchange offer, within ten (10) Business Days after the commencement of such tender offer or exchange offer and confirming that the Board Recommendation remains in effect and that the Company Board has not changed the Board Recommendation, shall be considered an adverse modification), (B) approve, recommend or declare advisable, or propose publicly to approve, recommend or declare advisable, any Acquisition Proposal, (C) after public announcement of an Acquisition Proposal (other than in connection with the commencement of a tender offer or exchange offer), fail to publicly confirm

(such public confirmation, a “Recommendation Confirmation”) that the Board Recommendation remains in effect and that the Company Board has not changed the Board Recommendation (the “Recommendation Confirmation Language”) within five (5) Business Days after a written request by Parent to do so (or, if earlier, by the close of business on the Business Day immediately preceding the scheduled date of the consummation of the Offer); provided, that Parent may only make such request once with respect to any Acquisition Proposal, and, provided further, that in each press release relating to such an Acquisition Proposal subsequent to a Recommendation Confirmation with respect thereto, the Company shall not fail to include the Recommendation Confirmation Language, or (D) fail to include the Board Recommendation in the Schedule 14D-9 when disseminated to the Company’s stockholders (any action described in this clause (i) being referred to as a “Change in Recommendation”) or (ii) approve, recommend or declare advisable, or propose publicly to approve, recommend or declare advisable, or enter into, any Contract, letter of intent, agreement in principle, memorandum of understanding or similar agreement with respect to any Acquisition Proposal, other than an Acceptable Confidentiality Agreement (an “Alternative Acquisition Agreement”).

(d) Notwithstanding anything to the contrary contained in this Agreement, at any time prior to the consummation of the Offer, the Company Board may make a Change in Recommendation in response to an Intervening Event if (i) the Company Board determines in good faith, after consultation with its outside legal counsel, that the failure to do so would reasonably be expected to be inconsistent with the Company Board’s fiduciary duties under Applicable Law, (ii) (A) the Company shall have provided Parent four (4) Business Days’ prior written notice of its intention to make a Change in Recommendation prior to making any such Change in Recommendation, which notice shall describe the reasons therefore and the Intervening Event in reasonable detail (provided, that such notice shall not constitute a Change in Recommendation) and (B) if requested by Parent in good faith, during such four (4) Business Day period after providing such notice, negotiate (and direct its Representatives to negotiate) in good faith with Parent and its Representatives respect to any revisions to the terms of this Agreement or another proposal to the extent proposed by Parent so that a Change in Recommendation would no longer be necessary, and (iii) after giving effect to all revisions and proposals contemplated by the foregoing clause (ii), if any, after consultation with outside legal counsel, the Company Board shall have determined in good faith that failure to make the Change in Recommendation in response to such Intervening Event would reasonably be expected to be inconsistent with its fiduciary duties under Applicable Law. For the avoidance of doubt, in the event of any material change in any event, occurrence or facts relating to such Intervening Event (other than in respect to any revisions proposed or proposals made by Parent as referred to above), a new notice shall be required from the Company pursuant to Section 6.02(d)(ii), except that the references to four (4) Business Days in this Section 6.02(d) shall be deemed to be three (3) Business Days, and the provisions of this Section 6.02(d) shall otherwise apply to the Intervening Event as modified thereby.

(e) Notwithstanding anything to the contrary contained in this Agreement, at any time prior to the consummation of the Offer if, in response to a bona fide written Acquisition Proposal made after the date of this Agreement and not withdrawn that did not result from a breach of this Section 6.02, the Company Board determines in good faith (after consultation with its outside legal counsel and financial advisors) that (i) such Acquisition Proposal constitutes a Superior Proposal and (ii) the failure to take the action set forth in clause

(A) or (B), as applicable, would reasonably be expected to be inconsistent with its fiduciary obligations under Applicable Law, then (A) subject to compliance with Section 6.02(f), the Company Board may make a Change in Recommendation or (B) subject to the Company’s compliance with all other requirements for termination of this Agreement pursuant to Section 8.01(d)(i), the Company may terminate this Agreement pursuant to Section 8.01(d)(i) in order to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal.

(f) Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be entitled to make a Change in Recommendation pursuant to Section 6.02(e) or terminate this Agreement pursuant to Section 8.01(d)(i) unless (x) the Company shall have provided to Parent four (4) Business Days’ prior written notice (the “Superior Proposal Notice”), (provided, that such notice shall not constitute a Change in Recommendation), advising Parent that the Company intends to take such action (and specifying, in reasonable detail, the reasons for such action and the material terms and conditions of any such Superior Proposal) and providing Parent with a copy of the Alternative Acquisition Agreement (and any other documents containing the terms of such Superior Proposal) in the form to be entered into (provided that Parent shall be required to keep all such documents and their terms confidential in accordance with the terms of the Confidentiality Agreement), and (y):

(i) during such four (4) Business Day period, if requested by Parent in good faith, the Company and its Representatives shall have engaged in good faith negotiations with Parent regarding changes to the terms of this Agreement and any other proposals made by Parent intended by Parent to cause such Acquisition Proposal to no longer constitute a Superior Proposal; and

(ii) the Company Board shall have considered in good faith any and all adjustments to this Agreement (including a change to the price terms hereof) and any other agreements that may be proposed in writing by Parent (the “Proposed Changed Terms”) no later than 11:59 p.m., New York City time, on the fourth (4th) Business Day of such four (4) Business Day period and shall have determined in good faith (after consultation with its outside legal counsel and financial advisors) that the Acquisition Proposal would continue to constitute a Superior Proposal if such Proposed Changed Terms were to be given effect, and that the failure to make the Change in Recommendation or terminate this Agreement pursuant to Section 8.01(d)(i) would reasonably be expected to be inconsistent with the Company Board’s fiduciary obligations under Applicable Law.

For the avoidance of doubt, any (1) material revisions to the terms of a Superior Proposal or (2) material revisions to an Acquisition Proposal that the Company Board had determined no longer constitutes a Superior Proposal, shall constitute a new Acquisition Proposal and shall in each case require the Company to deliver to Parent a new Superior Proposal Notice, except that the references to four (4) Business Days in this Section 6.02(f) shall be deemed to be three (3) Business Days.

(g) The Company shall promptly (and in any event within twenty-four (24) hours after receipt) advise Parent orally or in writing in the event that the Company receives any Acquisition Proposal or any inquiry, proposal or request for information that could reasonably be expected to lead to, or result in, an Acquisition Proposal, and in connection with

such notice, provide to Parent the material terms and conditions (including the identity of the Third Party making any such Acquisition Proposal) of any such Acquisition Proposal. The Company shall (i) keep Parent reasonably informed on a current basis of the status, material details and material terms of any such Acquisition Proposal (including, prior to furnishing any information or to participating in any discussions or negotiations pursuant to Section 6.02(b), advising Parent of any determination by the Company Board pursuant to Section 6.02(b)) and any discussions and negotiations concerning the material terms and conditions thereof and (ii) promptly provide to Parent (and in any event no later than twenty-four (24) hours after receipt or delivery thereof) any written proposal, indication of interest (or amendment thereto) or any other written material that constitutes an Acquisition Proposal (or amendment thereto) including copies of any proposed Alternative Acquisition Agreements and any financing commitments related thereto.

(h) Nothing contained in this Agreement shall prohibit the Company or the Company Board, directly or indirectly through their respective Representatives, from (i) taking and disclosing to the stockholders of the Company any position contemplated by Rule 14d-9, Rule 14e-2(a) or Item 1012(a) of Regulation M-A promulgated under the Exchange Act, (ii) making any “stop, look and listen” communication to the Company’s stockholders pursuant to Rule 14d-9(f) promulgated under the Exchange Act or (iii) making any disclosure to the stockholders of the Company that the Company has determined in good faith (after consultation with its outside legal counsel) is required by Applicable Law; provided, that this Section 6.02(h) shall not be deemed to permit the Company Board to make a Change in Recommendation except to the extent permitted by Section 6.02(d) - (f) and any disclosure contemplated by clause (i) or (ii) of this Section 6.02(h) shall be deemed a Change in Recommendation unless the Company Board expressly confirms that the Board Recommendation remains in effect and that the Board Recommendation has not changed in such disclosure.

Section 6.03. Approval of Merger. The Merger shall be governed by Section 251(h) of the DGCL and shall be effected by Parent, Merger Sub and the Company as soon as practicable following the consummation of the Offer, without a stockholder vote, pursuant to Section 251(h) of the DGCL.

the consummation of the Transactions; provided, however, that any such access shall be conducted at Parent’s expense, at a reasonable time, under the supervision of appropriate personnel of the Acquired Companies and in such a manner as not to unreasonably interfere with the normal operation of the business of the Acquired Companies. Nothing herein shall require any of the Acquired Companies to disclose any information to Parent if such disclosure would, in the Company’s reasonable discretion (i) jeopardize any attorney-client or other legal privilege (so long as the Acquired Companies have reasonably cooperated with Parent to permit such inspection of or to disclose such information on a basis that does not waive such privilege with respect thereto) or (ii) contravene any Applicable Law, fiduciary duty or binding confidentiality obligation of any Acquired Company or its Affiliate (so long as the Company has used commercially reasonable efforts to make appropriate substitute arrangements to permit reasonable disclosure not in violation of such Applicable Law, agreement or duty); provided, further, that information shall be disclosed subject to the execution of a joint defense agreement in customary form, and disclosure may be limited to external counsel for Parent, in each case, to the extent that the Company determines that doing so may be reasonably required for the purposes of complying with applicable Antitrust Laws.

(b) No information or knowledge obtained by Parent or Merger Sub pursuant to Section 6.02, this Section 6.04 or otherwise shall affect or be deemed to affect or modify any representation, warranty, covenant or agreement contained herein, the conditions to the obligations of the parties to consummate the Merger in accordance with the terms and provisions hereof or otherwise prejudice in any way the rights and remedies of Parent or Merger Sub hereunder, nor shall any such information, knowledge or investigation be deemed to affect or modify Parent’s or Merger Sub’s reliance on the representations, warranties, covenants and agreements made by the Company in this Agreement.

(c) Each party acknowledges that all information provided to it or any of its Representatives by the other party or any of such party’s Representatives in connection with this Agreement and the consummation of the Transactions shall be deemed to be provided under, and shall be treated in accordance with, the Confidentiality Agreement.

For a period of one (1) year following the Effective Time, Parent shall provide, or shall cause to be provided, to each Continuing Employee (i) base salary and base wages, short-term cash incentive compensation opportunities and severance payments and severance benefits (in the case of severance plans and benefits, in each case, in accordance with the severance plans and guidelines described on Section 6.06 of the Company Disclosure Schedules, as amended pursuant to item 9 of Section 6.01(b)(xix) of the Company Disclosure Schedules), in each case in an amount no less favorable than that in effect immediately prior to the execution of this Agreement and (ii) other benefits (other than equity compensation) that are substantially comparable in the aggregate to the other such benefits provided to such Continuing Employees immediately prior to the execution of this Agreement.

(b) From and after the Closing Date, with respect to Continuing Employees, Parent shall cause the service of each such Continuing Employee with the Company and the Company Subsidiaries prior to the Closing Date to be recognized for purposes of eligibility to participate, levels of benefits (but not for benefit accruals or participation eligibility under any defined benefit pension plan or plan providing post-retirement medical or other similar benefits) and vesting under each compensation, vacation, fringe or other welfare benefit plan, program or arrangement of the Surviving Corporation, but not including any sabbatical or equity compensation plans, programs, agreements or arrangements (collectively, the “Parent Benefit Plans”) in which any Continuing Employee is or becomes eligible to participate, but solely to the extent that service was credited to such employee for such purposes under a comparable Company Employee Plan immediately prior to the Closing Date and to the extent that such credit would not result in a duplication of benefits.

(c) From and after the Closing Date, with respect to each Parent Benefit Plan that is an “employee welfare benefit plan” as defined in Section 3(1) of ERISA in

which any Continuing Employee is or becomes eligible to participate, Parent shall use commercially reasonable efforts to cause each such Parent Benefit Plan to waive all limitations as to pre-existing conditions, waiting periods, required physical examinations and exclusions with respect to participation and coverage requirements applicable under such Parent Benefit Plan for such Continuing Employees and their eligible dependents to the same extent that such pre-existing conditions, waiting periods, required physical examinations and exclusions would not have applied or would have been waived under the corresponding Company Employee Plan in which such Continuing Employee was a participant immediately prior to his commencement of participation in such Parent Benefit Plan but only to the extent permitted under the terms and conditions of Parent’s applicable insurance Contracts in effect as of the Closing Date.

(d) Prior to the Closing Date, the Company will reasonably cooperate with Parent to provide updates to the Section 280G Information, if any, following the date hereof and to provide such other related information as reasonably requested by Parent.

(e) With respect to any accrued but unused personal, sick or vacation time to which any Continuing Employee is entitled pursuant to the personal, sick or vacation policies applicable to such Continuing Employee immediately prior to the Effective Time, Parent shall, or shall cause the Surviving Corporation to and instruct its Affiliates to, as applicable (and without duplication of benefits), assume the liability for such accrued personal, sick or vacation time and allow such Continuing Employee to use such accrued personal, sick or vacation time in accordance with the practice and policies of the Company, as they may be amended from time to time.

(f) Parent, the Company and the Surviving Corporation acknowledge and agree that all provisions contained in this Section 6.06 are included for the sole benefit of the respective parties to this Agreement and shall not create any right in any other Person, including any Company Employee, any participant in any Company Employee Plan or Parent Benefit Plan or any beneficiary thereof or any right to continued employment with Parent, Company, the Surviving Corporation or any of their Affiliates. Nothing in this Section 6.06 shall be deemed to amend any Company Employee Plan, any Parent Benefit Plan or to require Parent, the Surviving Corporation or any of their Affiliates to permit any Person to participate in any particular benefit plan sponsored or maintained by Parent or any of its Affiliates, or to continue or amend any particular benefit plan, before or after the consummation of the Transactions, and any such plan may be amended or terminated in accordance with its terms and Applicable Law.

Section 6.07. State Takeover Laws. If any “control share acquisition,” “business combination,” “fair price,” “moratorium” or other anti-takeover Applicable Law may become or is deemed or purports to be applicable to any Transaction, then each of the Company, Parent, Merger Sub, and their respective Boards of Directors shall use their respective reasonable best efforts to (i) take such actions as are necessary so that the Transactions may be consummated as promptly as practicable on the terms contemplated hereby and (ii) otherwise act to render such anti-takeover Applicable Law (or, in the case of Section 203 of the DGCL, the restrictions on business combinations provided therein) inapplicable to or to minimize the effects of the foregoing.

Section 6.08. Obligations of Parent. Parent shall cause Merger Sub to perform its obligations under this Agreement and to consummate the Offer and the Merger on the terms and conditions set forth in this Agreement.

Section 6.09. Director and Officer Liability.

(a) Prior to the Closing, the Company shall use its reasonable best efforts to purchase (in consultation with Parent) a “tail” or “runoff” officers’ and directors’ liability insurance policy in respect of acts or omissions occurring prior to the Effective Time covering each such person currently covered by the Company’s officers’ and directors’ liability insurance policy on terms with respect to coverage, deductibles and amounts no less favorable than those of such policy in effect on the date of this Agreement for the six (6) year period following the Closing and at a price not to exceed three hundred percent (300%) of the amount per annum the Company paid in its last full fiscal year prior to the date of this Agreement (the “Current Premium”). If the Company or Parent obtains prepaid “tail” or “runoff” policies prior to the Effective Time in accordance with this Section 6.09(a), the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain such policies in full force and effect for their full term, and continue to honor the obligations thereunder. If the Company fails to purchase such “tail” or “runoff” policy prior to Closing, then either (i) Parent may purchase such “tail” or “runoff” policy on behalf of the Company or the Surviving Corporation or (ii) the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain an officers’ and directors’ liability insurance policy in respect of acts or omissions occurring prior to the Effective Time covering each such person currently covered by the Company’s officers’ and directors’ liability insurance policy on terms with respect to coverage and amount no less favorable than those of such policy in effect as of the date of this Agreement for a period of six (6) years after the Effective Time; provided further, that in satisfying its obligation under this Section 6.09(a)(ii), neither Parent nor the Surviving Corporation shall be obligated to pay annual premiums in excess of three hundred percent (300%) of the Current Premium and if such premiums for such insurance would at any time exceed three hundred percent (300%) of the Current Premium, then Parent or the Surviving Corporation shall cause to be maintained policies of insurance that, in Parent or the Surviving Corporation’s good faith judgment, provide the maximum coverage available at an annual premium equal to three hundred percent (300%) of the Current Premium.

(b) From and after the Effective Time, Parent shall cause the Surviving Corporation to fulfill and honor in all respects the obligations of the Company and the Company Subsidiaries pursuant to (i) each indemnification agreement that is in effect between the Company or any of the Company Subsidiaries and any individual who at the Effective Time is, or at any time prior to the Effective Time was, a director or officer of the Company or of a Company Subsidiary (each, an “Indemnified Party”) and was Made Available to Parent; and (ii) any indemnification provision and any exculpation provision set forth in the certificate of incorporation or bylaws of the Company as in effect on the date of this Agreement. From the Effective Time through the sixth (6th) anniversary of the date on which the Effective Time occurs, the certificate of incorporation and bylaws of the Surviving Corporation shall contain, and Parent shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of

expenses and exculpation of each Indemnified Party than are set forth in the certificate of incorporation and bylaws of the Company as in effect on the date of this Agreement.

(c) If Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Parent or the Surviving Corporation, as applicable, shall assume the obligations set forth in this Section 6.09.

(d) The provisions of this Section 6.09 are (i) intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and his or her or their trustees or administrators or persons acting in similar capacities and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such individual may have under the certificate of incorporation or bylaws, by Contract or otherwise.

Section 6.10. Efforts.

(a) Subject to the terms and conditions of this Agreement, the Company and Parent shall (and shall cause their respective Subsidiaries to) each use their 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 under Applicable Law to consummate and make effective the Transactions as promptly as practicable and in any event prior to the End Date, including (i) the obtaining of all necessary actions, waivers, registrations, permits, authorizations, orders, consents and approvals from Governmental Authorities, the expiry or early termination of any applicable waiting periods, and the making of all necessary registrations and filings (including filings with Governmental Authorities, if any) and the taking of all steps as may be reasonably necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Authorities, (ii) the delivery of required notices to, and the obtaining of required consents or waivers from, Third Parties necessary to consummate the Transactions and (iii) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of this Agreement, including the execution and delivery of the Company Closing Representation Letter and the Parent Closing Representation Letter (in each case, as defined in the Tri-Party Agreement).

(b) In furtherance and not in limitation of the undertakings pursuant to this Section 6.10, each of Parent and the Company shall (i) prepare and file any notification and report forms and related material required under the HSR Act and other applicable Antitrust Laws with respect to the Transactions as set forth on Section 6.10(b) of the Company Disclosure Schedules, and any additional filings or notifications and related material that are necessary, proper or advisable to permit consummation of the Transactions, as promptly as reasonably practicable and advisable, (ii) provide or cause to be provided as promptly as reasonably practicable and advisable any information and documentary material that may be requested by the DOJ or FTC under the HSR Act or by other Governmental Authorities under applicable Antitrust Laws (if any) and (iii) use their reasonable best efforts to take such actions as are necessary or advisable to obtain prompt expiration or termination of any applicable waiting

period or other approval of consummation of the Transactions by the DOJ or FTC or other applicable Governmental Authorities. Parent shall pay all filing fees payable pursuant to the HSR Act or other applicable Antitrust Laws (if any).

(c) Subject to Applicable Law, the Company and Parent and their respective counsel shall (i) cooperate in all respects with each other in connection with any filing or submission with a Governmental Authority in connection with the Transactions and in connection with any investigation or other inquiry by or before a Governmental Authority relating to the Transactions, including any proceeding initiated by a private person, (ii) have the right to review in advance, and to the extent practicable each shall consult the other on, any material filing made with, or written materials to be submitted to, any Governmental Authority in connection with the Transactions and of any material communication received or given in connection with any proceeding by a private Person, in each case regarding any of the Transactions, (iii) promptly inform each other of any material communication (or any other material correspondence or memoranda) received from, or given to, the DOJ or the FTC or any other applicable Governmental Authority and (iv) promptly furnish each other with copies of all correspondence, filings and written communications between them or their Subsidiaries or Affiliates, on the one hand, and any Governmental Authority or its respective staff, on the other hand, with respect to the Transactions. The Company and Parent shall (with respect to any in-person discussion or meeting), and shall to the extent practicable (with respect to any telephonic discussion or meeting), provide the other party and its counsel with advance notice of and the opportunity to participate in any material discussion or meeting with any Governmental Authority in respect of any filing, investigation or other inquiry in connection with the Transactions. Notwithstanding the foregoing, Parent shall, following consultation with the Company and after giving due consideration to its views and acting reasonably and in good faith, and subject to Parent’s obligations under Section 6.10(d), direct and control all aspects of the parties’ efforts to gain regulatory clearance either before any Governmental Authority or in any action brought to enjoin the Transactions pursuant to any Antitrust Laws; provided, that each of the parties hereto shall have the right to review in advance, and to the extent practicable each will consult the other on, all the information relating to the other parties and their respective Subsidiaries, as the case may be, that appears in any filing made with, or written materials (including correspondence) submitted to, any Third Party and/or any Governmental Authority in connection with any governmental inquiry, investigation or proceeding with respect to the Transactions. The Company and Parent may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 6.10 as “Antitrust Counsel Only Material.” Notwithstanding anything to the contrary in this Section 6.10, materials provided to the other party or its counsel may be redacted to remove references concerning the valuation of the Company and the Company Subsidiaries.

(d) Without limiting the generality of the undertakings of Parent pursuant to Section 6.10(a) and Section 6.10(b), Parent shall, and shall cause each of its Subsidiaries to, take any and all steps necessary to avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority or any other Person so as to enable the parties hereto to consummate the Transactions as promptly as practicable, and in any event prior to the End Date, including (i) agreeing to sell, divest or otherwise convey or hold separate any particular assets or categories of assets or businesses of the Company or its Subsidiaries, (ii) permitting the Company to sell, divest or otherwise convey

or hold separate any of the particular assets or categories of assets or businesses of the Company or any of its Subsidiaries prior to the Effective Time, (iii) terminating existing relationships, contractual rights or obligations of the Company or its Subsidiaries, (iv) terminating any joint venture or other arrangement of the Company or its Subsidiaries or (v) creating any relationship, contractual right or obligation of the Company or its Subsidiaries (or, in each case, entering into agreements or stipulating to the entry of any Order by, or filing appropriate applications with, the FTC, the DOJ or any other Governmental Authority in connection with any of the foregoing and, in the case of actions by or with respect to the Company, by consenting to such action by the Company (including any consents required under this Agreement with respect to such action)) (each of the actions described in clauses (i)—(v), a “Divestiture Action”); provided, however, that in no event shall anything in this Agreement require, or be construed to require, the Company, Parent or any of their respective Affiliates to (1) take, or agree to take, any Divestiture Action unless all Divestiture Actions collectively would not result in a material adverse effect on the business, results of operations, assets or financial condition of the Company and its Subsidiaries, taken as a whole or (2) take any actions, including the actions described in clauses (i)—(v) above with respect to Parent, its Affiliates or their respective assets, categories of assets, businesses, relationships, contractual rights, obligations or arrangements. To assist Parent in complying with its obligations set forth in this Section 6.10(d), the Company shall enter into one or more agreements requested by Parent to be entered into by any of them prior to the Closing (but conditioned upon consummation of the Closing) with respect to any Divestiture Action. Parent shall respond to and seek to resolve as promptly as reasonably practicable any objections asserted by any Governmental Authority with respect to the Transactions, and the Company, Parent and Merger Sub and any of their respective Affiliates shall not take any action with the intention to, or that would reasonably be expected to, hinder or delay the expiration or termination of any waiting period under the HSR Act or the obtaining of approval of the DOJ or FTC or under any other applicable Antitrust Laws. Nothing in this Agreement shall require any party to take or agree to take any action with respect to its business or operations in connection with obtaining the expiration or termination of the applicable waiting periods under, or any approvals under, the HSR Act or other applicable Antitrust Laws or approvals from any other Governmental Authorities, unless the effectiveness of such agreement or action is conditioned upon the Closing.

The Company shall (x) give Parent the right to review and comment on all material filings or responses to be made by the Company and shall discuss in advance any material discussions or communications proposed to be held by the Company with any Third Party in connection with any Stockholder/Transaction Litigation (and the Company shall in good faith take any comments or feedback provided by Parent into account), and the opportunity to participate in the defense and settlement of, any Stockholder/Transaction Litigation and (y) if Parent does not exercise such right to participate (subject to the Company’s control right), keep Parent reasonably and promptly informed with respect to the status of such Stockholder/Transaction Litigation; provided, however, that the disclosure of information in connection therewith shall be subject to the provisions of Section 6.04, including regarding

attorney-client privileges and other applicable legal privileges. No compromise or full or partial settlement of any Stockholder/Transaction Litigation shall be agreed to by the Company without Parent’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

The parties hereto agree that the initial press release to be issued with respect to the Transactions shall be a joint press release, in a form mutually agreed to by the parties hereto, and shall be issued as promptly as practicable following the execution and delivery of this Agreement (and in no event later than 8:30 a.m., Paris time, on January 22, 2018). Parent and the Company shall consult with each other before issuing any other press release, or scheduling a press conference or conference call with investors or analysts, and shall use reasonable best efforts to consult with each other before making any other public statement, in each case with respect to this Agreement or the Transactions and shall not issue any such press release or make any such other public statement without the consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed, except for any such release or announcement that Parent or the Company determines, after consultation with outside legal counsel, is required by Applicable Law or any listing agreement with or rule of any national or foreign securities exchange or association upon which the securities of the Company or Parent, as applicable, are listed, in which case the party required to make the release or announcement shall provide notice to and, to the extent reasonably practicable, consult with the other party about, and shall use its commercially reasonable efforts to allow the other party reasonable time (taking into account the circumstances) to comment on, such release or announcement in advance of such issuance, and the party will consider any such reasonable comments that are timely provided in good faith; provided, however, each party may, without such consultation or consent, make any public statement in response to questions from the press, analysts, investors or those attending industry conferences, make internal announcements to employees and make disclosures in Company SEC Documents and any documents, reports, statements, forms or other filings required to be made by Parent with the SEC or equivalent foreign Governmental Authority, so long as such statements, announcements and disclosures substantially reiterate (and are not inconsistent with) previous press releases, public disclosures or public statements made jointly by the parties (or individually, if approved in advance by the other party); and provided further that, notwithstanding the foregoing, neither Parent nor the Company shall be required to consult with the other parties hereto before issuing any press release or making any other public statement with respect to any Change in Recommendation, Acquisition Proposal or Intervening Event; provided further that nothing in this Section 6.12 shall be deemed to modify or limit, and the ability to make any disclosures or statements pursuant to the immediately preceding proviso shall be subject to, the Company’s obligations under Section 6.02.

(f) The Company acknowledges that the agreements contained in this Section 9.04 are an integral part of the Transactions and that without such provisions Parent and Merger Sub would not have entered into this Agreement.

(g) If the Company fails to pay the Termination Fee or any portion thereof and Parent or Merger Sub commences a suit which results in an Order against the Company for the Termination Fee or any portion thereof, the Company shall pay Parent and Merger Sub their costs and expenses (including reasonable attorney’s fees and disbursements) in connection with such suit, together with interest on the Termination Fee (or any portion thereof that has not been paid timely in accordance with this Agreement) and on the amount of such costs and expenses, in each case from and including the date payment of such amount was due to through the date of actual payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made. Any amounts payable pursuant to this Section 9.04 shall be paid to Parent by wire transfer of immediately available funds. Parent shall promptly provide the Company upon request therefor the wire transfer information required to make any payments pursuant to this Section 9.04.

(h) Notwithstanding anything herein to the contrary, other than in the case of fraud or a Willful Breach by the Company, Parent’s right to receive payment from the Company of the Termination Fee pursuant to Sections 9.04(b) - (d) and any payments pursuant to Section 9.04(g) shall be the sole and exclusive remedy of any of Parent, Merger Sub or any of their respective Affiliates or representatives against the Company and any of its former, current or future officers, directors, partners, stockholders, Company Stock Option holders, Company Restricted Stock Unit holders, managers, members or Affiliates (collectively, the “Company Related Parties”) for any loss suffered as a result of the failure of the Transactions to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of the Termination Fee, none of the Company Related Parties shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions.

Section 9.05. Assignment; Benefit. Neither this Agreement nor any of the rights, interests or obligations herein may be assigned by any party hereto without the prior written consent of the other parties and any purported assignment in violation hereof shall be null and void ab initio; provided that Parent or Merger Sub, upon prior written notice to the Company, may assign, in its sole discretion (provided that such assignment shall not impede or delay the consummation of the Offer or the Merger or otherwise impede the rights of stockholders of the Company under this Agreement), any of or all its rights, interests and obligations under this Agreement to Parent or to any direct or indirect wholly-owned Subsidiary of Parent; provided, further, that no such assignment shall relieve Parent or Merger Sub of any of its obligations hereunder. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement, expressed or implied, is intended to confer on any Person other than the parties hereto and their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except (i) from and after the consummation of the Offer, the provisions of Article 2 relating to the payment of the Per Share Amount, which shall be enforceable by the holders of Shares immediately prior to the consummation of the Offer who validly tendered and did not withdraw Shares pursuant to the Offer, (ii) from and after the Effective Time, (A) the provisions of Article 2 relating to the payment of the Per Share Amount and the Option Consideration, which shall be enforceable by the holders of Company Common

Stock and Company Equity Awards, as applicable, as of immediately prior to the Effective Time and (B) the provisions of Section 6.10 which shall be enforceable by the Persons or entities benefiting therefrom and (iii) the provisions of Section 9.04(h) which shall be enforceable by the Company Related Parties. In addition, the Company shall have the right to pursue claims for damages suffered by holders of Company Common Stock and Company Equity Awards (including the benefit of the bargain lost by such holders, taking into account without limitation the total amount payable to such holders under this Agreement, which shall be deemed to be damages of the Company, but only to the extent such claims are not pursued directly by such holders) and other relief, including equitable relief, in connection with any Willful Breach of this Agreement by Parent or Merger Sub. For the avoidance of doubt, other than as expressly set forth in this Section 9.05, no holder of Shares shall have any third party beneficiary rights under this Agreement.

Section 9.06. Governing Law. This Agreement and any Proceedings arising out of or related hereto or the Transactions or to the inducement of any party thereto to enter into this Agreement, (whether for breach of contract, tortious conduct or otherwise and whether predicated on common law statute or otherwise) shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state. The parties expressly acknowledge and agree that (a) the requirements of 6 Del. C § 2708 are satisfied by the provisions of this Agreement and that such statute mandates the application of Delaware law to this Agreement, the relationship of the parties, the Transactions and the interpretation and enforcement of the rights and duties of the parties hereunder (b) the parties have a reasonable basis for the application of Delaware law to this Agreement, the relationship of the parties, the Transactions and the interpretation and enforcement of the rights and duties of the parties hereunder, (c) no other jurisdiction has a materially greater interest in the foregoing and (d) the application of Delaware law would not be contrary to the fundamental policy of any other jurisdiction that, absent the parties’ choice of Delaware law hereunder, would have an interest in the foregoing.

Section 9.07. Jurisdiction. The parties hereto hereby irrevocably agree (i) that any Proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the Transactions shall be brought in the Chancery Court of the State of Delaware and any state appellate court therefrom, or, if no such state court has proper jurisdiction, the Federal District Court for the District of Delaware located in Wilmington, Delaware, and any appellate court therefrom and (ii) not to commence any such Proceeding in any court except such courts. Each party hereby irrevocably submits to the exclusive jurisdiction of such court in respect of any legal or equitable Proceeding arising out of or relating to this Agreement or the Transactions, or relating to enforcement of any of the terms of this Agreement, and hereby waives, and agrees not to assert, as a defense in any such Proceeding, any claim that it is not subject personally to the jurisdiction of such court, that the Proceeding is brought in an inconvenient forum, that the venue of the Proceeding is improper or that this Agreement or the Transactions may not be enforced in or by such courts. Each party agrees that notice or the service of process in any Proceeding arising out of or relating to this Agreement or the Transactions shall be properly served or delivered if delivered in the manner contemplated by Section 9.01 or in any other manner permitted by Applicable Law.

Section 9.08. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING ARISING DIRECTLY OR INDIRECTLY OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.08.

Section 9.09. Specific Performance; Remedies. The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, 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. Subject to the following sentence, it is accordingly agreed that (i) the parties shall be entitled to an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the courts described in Section 9.07, without proof of damages or otherwise, and (ii) the right of specific performance is an integral part of the Transactions and without that right, neither the Company nor Parent would have entered into this Agreement. Each of the parties agrees that it waives the defense of adequacy of a remedy at law and will not oppose the granting of an injunction or injunctions, specific performance or other equitable relief on the basis that (x) the other parties have an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 9.09 shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 9.10. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the Offer, the Merger and the other Transactions is not affected in any manner materially adverse to any party. Upon such a determination, the parties agree to negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner, in order that the Offer, the Merger and the other Transactions be consummated as originally contemplated to the fullest extent possible.

Section 9.11. Entire Agreement. This Agreement, including the exhibits to this Agreement, the Company Disclosure Schedules and any documents delivered by the parties in connection herewith, the Tri-Party Agreement and the Confidentiality Agreement constitute the

entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect thereto; provided, however, that, the Confidentiality Agreement shall not be superseded, shall survive any termination of this Agreement and shall continue in full force and effect until the earlier to occur of (a) the Effective Time and (b) the date on which the Confidentiality Agreement expires in accordance with its terms or is validly terminated by the parties thereto.

Section 9.12. Rules of Construction. Each of the parties hereto acknowledges that it has been represented by counsel of its choice throughout all negotiations that have preceded the execution of this Agreement, and that it has executed the same with the advice of said independent counsel. Each party and its counsel cooperated and participated in the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto exchanged among the parties shall be deemed the work product of all of the parties and may not be construed against any party by reason of its drafting or preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any party that drafted or prepared it is of no application and is hereby expressly waived by each of the parties hereto. Any matter set forth on the Company Disclosure Schedules shall not be deemed to constitute an admission by the Company or any Company Subsidiary, or to otherwise imply, that any such matter is material, is required to be disclosed by the Company under this Agreement or falls within relevant minimum thresholds or materiality standards set forth in this Agreement, nor shall be construed as an admission or indication to any Third Party that any breach or violation exists or has actually occurred.

Section 9.13. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto, it being understood and agreed that all parties hereto need not sign the same counterpart. Until and unless each party has received a counterpart hereof signed by each other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication). Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in PDF form, or by any other electronic means designed to preserve the original graphic and pictorial appearance of a document, will be deemed to have the same effect as physical delivery of the paper document bearing the original signatures.

Conditions of the Offer

The obligation of Merger Sub to accept for payment and pay for Shares validly tendered (and not validly withdrawn) pursuant to the Offer is subject to the satisfaction of the conditions set forth in clauses “(a)” through “(h)” below. Accordingly, notwithstanding any other term of the Offer or the Agreement to the contrary, Merger Sub shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC, including Exchange Act Rule 14e-l(c) (relating to Merger Sub’s obligation to pay for or return tendered Shares promptly after the termination or withdrawal of the Offer), pay for, and may delay the acceptance for payment of or, subject to such rules and regulations, the payment for, any tendered Shares and, if permitted by the Merger Agreement, may terminate the Offer: (i) if the Merger Agreement has been terminated in accordance with Section 8.01; and (ii) at any scheduled Offer Expiration Time (as the Offer may have been extended pursuant to, and subject to any requirements to extend the Offer pursuant to, Section 2.01(c) of the Merger Agreement), if: (A) the Minimum Tender Condition or the Termination Condition shall not be satisfied by the Offer Expiration Time; or (B) any of the additional conditions set forth below shall not be satisfied or (to the extent permitted by Applicable Law) waived in writing by Parent:

(a) there shall have been validly tendered in the Offer and not withdrawn that number of Shares that (together with any Shares owned by Parent and its Affiliates and excluding any Shares tendered pursuant to guaranteed delivery procedures that have not yet been “received” (as such term is defined in Section 251(h)(6)(f) of the DGCL)) represent at least a majority of the Shares outstanding at the Offer Expiration Time (the “Minimum Tender Condition”);

(b) (1) any waiting period (or any extension thereof) under the HSR Act applicable to the Transactions shall have expired or been terminated and (2) all consents of, and/or filings with, any Governmental Authority or pursuant to any Antitrust Laws set forth on Section 6.10(b) of the Company Disclosure Schedules shall have been obtained and be in full force and effect and any applicable waiting period with respect thereto shall have expired, as the case may be (it being understood that any consent shall be deemed obtained if the relevant merger control authority (A) has declared that it does not have jurisdiction, or has determined not to exercise its jurisdiction, to review the Transactions, (B) has consented to, approved, or cleared the Transactions or (C) may no longer prohibit the Transactions due to the expiry of all relevant time periods);

(c) no Order shall have been issued by a Governmental Authority and no Applicable Law shall be in effect that would (A) make the Offer or the Merger illegal or (B) otherwise prevent or prohibit the consummation thereof;

(d) since the date of the Merger Agreement, there shall not have occurred a Company Material Adverse Effect;

(e) (1) the representation and warranty of the Company set forth in Section 4.11(b) shall be true and correct in all respects as of the date of the Merger Agreement, (2) each

of the representations and warranties of the Company set forth in Sections 4.01, 4.03 and 4.27 of the Merger Agreement shall be true and correct in all material respects as of the consummation of the Offer, as if made at such time, except to the extent such representation or warranty expressly relates to a specific date (in which case on and as of such specific date), (3) the representations and warranties of the Company set forth in Section 4.06(a) shall be true and correct except for de minimis inaccuracies as of the consummation of the Offer, as if made at such time, except to the extent any such representation or warranty expressly relates to a specific date (in which case on and as of such specific date), and (4) each of the other representations and warranties of the Company set forth in the Merger Agreement shall be true and correct as of the consummation of the Offer, as if made at such time, except to the extent any such representation or warranty expressly relates to a specific date (in which case on and as of such specific date), other than in the case of clause (4) for such failures to be true and correct that have not had a Company Material Adverse Effect (it being understood that for this purpose all references to the term “Company Material Adverse Effect” and other qualifications based on the word “material,” set forth in any such representations and warranties shall be disregarded);

(f) the Company shall have complied with or performed in all material respects each of the covenants, obligations and agreements it is required to comply with or perform at or prior to the Effective Time;

(g) Parent and Merger Sub shall have received from the Company a certificate, signed by each of the Company’s Chief Executive Officer and Chief Financial Officer, dated the date on the which the Offer expires certifying that the conditions specified in clauses (d), (e), (f) and (i) have been satisfied;

(h) the Merger Agreement shall not have been terminated in accordance with its terms (the “Termination Condition”); and

(i) (1) the Company shall have received and delivered to Biogen and Parent the Company Closing Opinion (as defined in that certain Tri-Party Agreement, dated as of January 21, 2018, by and among Parent, the Company and Biogen (the “Tri-Party Agreement”)) and (2) the requirement that the Company deliver an Unqualified Tax Opinion (as defined in the TMA) pursuant to Section 7.01(c) of that certain Tax Matters Agreement, entered into as of January 31, 2017, by and between Biogen and the Company (the “TMA”) shall have been satisfied with respect to the Offer Closing (as defined in the Tri-Party Agreement) and the Closing pursuant to the terms of Section 1(h) of the Tri-Party Agreement.

The foregoing conditions are for the sole benefit of Parent and Merger Sub and, except for the Minimum Tender Condition and the Termination Condition (each of which may only be waived with the prior written consent of the Company), may be waived by Parent or Merger Sub in whole or in part at any time and from time to time and in the sole discretion of Parent or Merger Sub, subject in each case to the terms of the Merger Agreement and Applicable Law. Any reference in this Annex A or in the Merger Agreement to a condition or requirement being satisfied shall be deemed met if such condition or requirement is so waived. The foregoing conditions shall be in addition to, and not a limitation of, the rights and obligations of Parent and Merger Sub to extend, terminate and/or modify the Offer pursuant to the terms and conditions of the Merger Agreement or Applicable Law. The failure by Parent, Merger Sub or

any other Affiliate of Parent at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, the waiver of any such right with respect to particular facts and circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.

Capitalized terms used in this Annex A but not defined herein shall have the meanings set forth in the Agreement to which it is attached, except that the term “Merger Agreement” shall be deemed to refer to the Agreement to which this Annex A is attached.
