AGREEMENT AND PLAN OF MERGER

Agreement and Plan of Merger (this “Agreement”), dated as of April 5, 2011, among Merck & Co., Inc., a company formed under the laws of New Jersey (“Parent”), Monarch Transaction Corp., a Delaware corporation and a wholly-owned Subsidiary of Parent (“Merger Sub”), and Inspire Pharmaceuticals, Inc., a Delaware corporation (the “Company”). Capitalized terms not otherwise defined herein shall have the meaning set forth in Exhibit A attached hereto.

Recitals

WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the Company have approved and declared advisable this Agreement and the Transactions, including the Offer and the Merger, on the terms and subject to the conditions set forth in this Agreement;

WHEREAS, in furtherance of the Transactions, (a) Parent has agreed to cause Merger Sub to commence a cash tender offer (as it may be amended from time to time as permitted under this Agreement, the “Offer”) to purchase all the issued and outstanding shares of the common stock, par value $0.001 per share (the “Company Common Stock”) of the Company and the associated preferred stock purchase rights (the “Rights”, and together with the Company Common Stock, each a “Share” and collectively, the “Shares”) at a price per Share of $5.00 net to the seller in cash, without interest (such amount, or any higher amount per Share paid pursuant to the Offer in accordance with this Agreement, the “Offer Price”), on the terms and subject to the conditions set forth in this Agreement, and (b) the Company has granted to Merger Sub the Top-Up Option;

WHEREAS, following the consummation of the Offer, subject to the terms and conditions of this Agreement, Parent shall cause Merger Sub to merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned Subsidiary of Parent, in accordance with the General Corporation Law of the State of Delaware (the “DGCL”). Each Share that is not tendered and accepted pursuant to the Offer, other than certain Shares as provided in Section 2.5(b) and Section 2.6, will thereupon be cancelled and converted in the Merger into the right to receive cash in an amount equal to the Offer Price on the terms and subject to the conditions set forth herein; and

WHEREAS, concurrently with the execution and delivery of this Agreement, and as a condition and inducement to Parent’s and Merger Sub’s willingness to enter into this Agreement, (i) the Company’s Board of Directors has approved, and the Company and the Rights Agent have entered into, the Rights Amendment and (ii) a shareholder of the Company is entering into a Tender and Support Agreement with Parent (the “Tender and Support Agreement”), whereby such shareholder has agreed, among other things, upon the terms and subject to the conditions set forth therein, to tender its shares of Company Common Stock in the Offer and support any and all corporate action necessary to consummate the Merger.

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

ARTICLE 1.

THE OFFER

Section 1.1. The Offer.

(a) Subject to the terms and conditions set forth in this Agreement, as promptly as reasonably practicable after the date of this Agreement, but in no event later than ten (10) 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 under the Exchange Act) the Offer to purchase any and all outstanding Shares at a price per Share equal to the Offer Price. The obligations of Merger Sub to, and of Parent to cause Merger Sub to, purchase, accept for payment, and pay for, Shares tendered pursuant to the Offer are subject only to the satisfaction or waiver of each of the conditions set forth in Annex A (the “Offer Conditions”).

(b) The initial expiration date of the Offer shall be the twentieth (20th) Business Day following the commencement of the Offer (determined using Exchange Act Rules 14d-1(g)(3) and 14d-2) (such date being the initial “Expiration Date,” and any expiration time and date established pursuant to an authorized extension of the Offer as so extended, also an “Expiration Date”). Notwithstanding the foregoing, if, on the initial Expiration Date or any subsequent Expiration Date, all of the Offer Conditions have not been satisfied or waived (other than any Offer Conditions that by their nature cannot be satisfied until the closing of the Offer, which shall be required to be satisfied or waived at the closing of the Offer), then Merger Sub shall, and Parent shall cause Merger Sub to, subject to the rights of the parties under Article 8, extend (and re-extend) the Offer and its Expiration Date beyond the initial Expiration Date or such subsequent Expiration Date until the date all of the Offer Conditions are satisfied or waived (other than any Offer Conditions that by their nature cannot be satisfied until the closing of the Offer, which shall be required to be satisfied or waived at the closing of the Offer); provided that any such extension (i) shall be in increments determined by Merger Sub of not more than ten (10) Business Days and (ii) shall not extend beyond the Walk Away Date. The Offer may not be terminated prior to its Expiration Date (as such Expiration Date may be extended and re-extended in accordance with this Agreement), unless this Agreement is validly terminated in accordance with Article 8. In no event shall Merger Sub extend the Offer beyond the date that is five (5) Business Days prior to the Walk Away Date without the prior written consent of the Company in its sole discretion. Notwithstanding the foregoing, subject to the rights of the parties under Article 8, Merger Sub shall extend the Offer, and Parent shall cause Merger Sub to extend the Offer, for any period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer or any period required by any other Law.

(c) 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. Merger Sub shall, and Parent shall cause Merger Sub to, comply with the obligations respecting prompt payment and announcement under the Exchange Act, and, without limiting the foregoing, Merger Sub shall (and Parent shall cause Merger Sub to) accept for payment and pay for all Shares validly tendered and not properly withdrawn pursuant to the Offer as promptly as practicable following the later of: (i) the earliest date as of which Merger Sub is permitted under applicable Law to accept for payment Shares tendered pursuant to the

Offer and (ii) the earliest date as of which each of the Offer Conditions shall have been satisfied or waived.

(d) Merger Sub may, in its sole discretion (and without any required consent of the Company, but subject to the terms set forth in this Section 1.1(d)), elect to provide for a subsequent offering period (and one or more extensions thereof) in accordance with Rule 14d-11 under the Exchange Act (each a “Subsequent Offering Period”) following the Acceptance Time if (i) Merger Sub shall have complied with all of the conditions of Rule 14d-11 under the Exchange Act and (ii) at the commencement of any Subsequent Offering Period (or extension thereof) the number of Shares owned by Parent, Merger Sub and their respective Subsidiaries (including any Shares beneficially owned by any of the foregoing and including all Shares validly tendered and not properly withdrawn at the Acceptance Time) represent less than 90% of the then outstanding number of Shares; provided, however, that if Merger Sub is required to exercise the Top-Up Option pursuant to Section 1.4(c), Merger Sub shall not be permitted to provide for a Subsequent Offering Period. If immediately following the Acceptance Time, Parent, Merger Sub and their respective Subsidiaries own more than 70% but less than 90% of the Shares outstanding at that time (which shall include (i) shares beneficially owned by Parent, Merger Sub and their respective Subsidiaries, which Shares shall be converted into direct ownership at or prior to the expiration of the Offer by Parent, Merger Sub or their respective Subsidiaries, as the case may be, and (ii) shares validly tendered in the Offer and not properly withdrawn at the Acceptance Time), to the extent requested by the Company, Merger Sub shall provide for, and Parent shall cause Merger Sub to provide for, a Subsequent Offering Period of ten (10) Business Days; provided, however, that if Merger Sub is required to exercise the Top-Up Option pursuant to Section 1.4(c), the Company shall not have the right to request a Subsequent Offering Period; provided, further that the Company shall not have the right to request a Subsequent Offering Period if such Subsequent Offering Period would extend beyond the date that is five (5) Business Days prior to the Walk Away Date without the prior written consent of Parent (which consent may be withheld in its sole discretion). Subject to the terms and conditions set forth in this Agreement and the Offer, Parent shall cause Merger Sub to, and Merger Sub shall, accept for payment and pay for all Shares validly tendered and not properly withdrawn during such Subsequent Offering Period as promptly as practicable after any such Shares are tendered during any Subsequent Offering Period and in any event in compliance with Rule 14d-11(c) promulgated under the Exchange Act.

(e) Parent and Merger Sub expressly reserve the right to waive any of the Offer Conditions, to increase the Offer Price and/or to modify the other terms of the Offer, except that, without the prior written consent of the Company, Merger Sub shall not, and Parent shall not permit Merger Sub to, do any of the following:

(i) reduce the number of Shares subject to the Offer;

(ii) reduce the Offer Price;

(iii) amend, change or waive the Minimum Tender Condition;

(iv) except as expressly provided in Section 1.1(b), extend or otherwise change the Expiration Date, except (A) as required by applicable Law (including for any period

required by any rule, regulation, interpretation or position of the SEC or the staff thereof) or (B) in connection with an increase of the Offer Price;

(v) change the form of consideration payable in the Offer;

(vi) impose any condition to the Offer other than the Offer Conditions; or

(vii) otherwise amend, modify or supplement any of the Offer Conditions or the terms of the Offer in any manner adverse to 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 prevent, materially delay or impair the ability of the Parent or Merger Sub to consummate the Offer, the Merger or the other Transactions.

(f) On the date of commencement of the Offer, Parent and Merger Sub shall file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which Tender Offer Statement shall (i) contain or incorporate by reference an offer to purchase and a related letter of transmittal and summary advertisement and such other information or documents as required by Law (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, being referred to as the “Offer Documents”) and (ii) be in form reasonably satisfactory to the Company. The Company shall as promptly as practicable upon request of Parent, provide Parent and Merger Sub with all information concerning the Company that is required to be included in the Offer Documents. Parent and Merger Sub shall cause the Offer Documents to comply in all material respects with the requirements of applicable U.S. federal securities Laws 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 in writing specifically 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 necessary such that the Offer Documents do not contain an 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 are made, not misleading. 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 U.S. federal securities Laws. The Company and its counsel shall be afforded a reasonable opportunity to review and comment upon the Offer Documents each time before they are filed with the SEC and/or disseminated to holders of Shares (and the Company and its counsel shall provide any comments thereon as soon as reasonably practicable, 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 provide to the Company and its counsel copies of any written comments or telephonic notification of any oral comments or other communications 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 or other communications, shall consult with the Company and its counsel prior to responding to any such comments or other communications, and shall provide the Company with copies of all written responses and telephonic notification of any oral responses thereto of Parent or Merger Sub or their counsel, provided that Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to participate in the response of Parent and Merger Sub to any such comments or other communications and to provide comments on that response (to which reasonable and good faith consideration shall be given by Parent and Merger Sub).

(g) Unless this Agreement is terminated pursuant to Section 8.1, neither Parent nor Merger Sub shall terminate or withdraw the Offer without the prior written consent of the Company in its sole discretion, except that in the event this Agreement is terminated pursuant to Section 8.1, Merger Sub shall promptly (and in any event within one (1) Business Day) following such termination irrevocably and unconditionally terminate the Offer and shall not acquire any Shares pursuant thereto. If the Offer is terminated in accordance with this Agreement prior to the purchase of Shares in the Offer, Merger Sub shall promptly return, or cause any depositary acting on behalf of Merger Sub to return, all tendered Shares to the tendering stockholders.

(h) The Offer Price shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock effected by the Company in accordance with the terms and conditions of this Agreement and occurring (or for which a record date is established) after the date of this Agreement and prior to the payment by Merger Sub for the Shares validly tendered and not properly withdrawn in connection with the Offer.

Section 1.2. Company Actions.

(a) Subject to Section 6.8, and without limitation of the right to terminate this Agreement pursuant to Article 8, the Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated by this Agreement (the “Transactions”).

(b) Contemporaneously with the filing of the Offer Documents, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended and supplemented from time to time, the “Schedule 14D-9”) and shall disseminate the Schedule 14D-9 with respect to the Offer, to the extent required by Rule 14D-9 promulgated under the Exchange Act and any other applicable Laws, to the holders of the Shares concurrently with the mailing of the Offer Documents. Subject to the provisions of Section 6.8 below, the Offer Documents and the Schedule 14D-9 shall contain the Board Recommendation, and the Company hereby consents to the inclusion in the Offer Documents of such recommendation. The Company shall, after receiving the written consent of its financial advisor, also include in the Schedule 14D-9 (or in an Annex thereto), in its entirety, a copy of the opinion of the Company Financial Advisor described in Section 3.16. The Schedule 14D-9 shall comply in all material respects with the requirements of applicable U.S. federal securities Laws and, on the date first filed with the SEC and on the date first published, sent or given to the Company’s stockholders, shall 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 therein, in light of the circumstances under which they were made, not misleading, except that the Company makes no covenant, agreement, representation or warranty with respect to information supplied by Parent or Merger Sub in writing specifically for inclusion in the Schedule 14D-9. Each of the Company, Parent and Merger Sub shall promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent necessary such that the Schedule 14D-9 does 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 therein, in light of the circumstances under which they are made, not misleading. The Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9 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 U.S. federal securities Laws.

(c) Except in connection with either (i) a Takeover Proposal that the Board of Directors of the Company (the “Company Board”) determines in good faith (after consultation with the Company’s outside counsel and financial advisor(s)) constitutes or is reasonably likely to lead to a Superior Proposal or (ii) a Company Adverse Recommendation Change, in each case subject to the terms and conditions of Section 6.8:

(A) Parent and its counsel shall be afforded a reasonable opportunity to review and comment upon the Schedule 14D-9 before it is filed with the SEC and disseminated to holders of Shares; and

(B) The Company shall provide Parent and its counsel copies of any written comments or telephonic notification of any oral comments or other communications the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments or other communications, shall consult with Parent and its counsel prior to responding to any such comments or other communications, and shall provide Parent with copies of all written responses and telephonic notification of any oral responses thereto of the Company and its counsel. Parent and its counsel shall be given a reasonable opportunity to participate in the response of the Company to any such comments or other communications and to provide comments on that response (to which reasonable and good faith consideration shall be given by the Company).

(d) In connection with the Offer and the Merger, the Company shall instruct its transfer agent to furnish Merger Sub promptly with mailing labels containing the names and addresses of the record holders of Shares as of the most recent practicable date and of those Persons becoming record holders subsequent to such date, together with copies of all available lists of stockholders, security position listings and computer files and all other information in the Company’s possession or control regarding the beneficial owners of Shares, and shall furnish to Merger Sub such information and assistance (including updated lists of stockholders, security position listings and computer files) as Parent may reasonably request, in each case, for the purpose of communicating the Offer to the holders of Shares. Subject to the requirements of applicable Law and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer, the Merger and the other Transactions, Parent and Merger Sub shall, until consummation of the Offer, hold in confidence the information contained in any of such labels and lists in accordance with the Confidentiality

Agreement, shall use such information only in connection with the Offer, the Merger and the other Transactions and, if this Agreement shall be terminated in accordance with Section 8.1, shall deliver to the Company or destroy, at Parent’s election, all copies of such information then in their possession or under their control in accordance with the Confidentiality Agreement.

Section 1.3. Directors.

(a) Subject to applicable Law and applicable marketplace rules of The NASDAQ Stock Market LLC applicable to the Company at such time, promptly following the acceptance for payment of and payment by Merger Sub for Shares pursuant to and in accordance with the Offer satisfying the Minimum Tender Condition (the “Acceptance Time”), and as long as Parent directly or indirectly beneficially owns not less than a majority of the issued and outstanding Shares, Merger Sub shall be entitled to designate such number of directors on the Company Board as will give Merger Sub representation on the Company Board equal to that number of directors, rounded up to the next whole number, that is the product of (i) the total number of directors on the Company Board (giving effect to the directors elected pursuant to this sentence) multiplied by (ii) the percentage that (A) the number of Shares owned by Parent, Merger Sub or any other Subsidiary of Parent bears to (B) the total number of Shares that are issued and outstanding. The Company shall also, upon the request of Parent, cause such persons designated by Merger Sub to constitute at least the same percentage (rounded up to the next whole number) as is on the Company Board of each committee of the Company Board, subject to compliance with applicable securities Laws and the marketplace rules of The NASDAQ Stock Market LLC (other than any committee comprised solely of Continuing Directors established to take action under this Agreement, which shall be permitted to meet without the presence of other directors solely for purposes of considering and, if necessary, taking action referred to in Section 1.3(c) below); provided, however, that in the event that Merger Sub’s designees are appointed or elected to the Company Board, until the Effective Time, the Company Board shall have at least two (2) directors who are directors on the date of this Agreement and who qualify as independent directors for purposes of the continued listing requirements of The NASDAQ Stock Market LLC and the SEC rules and regulations (such directors, the “Continuing Directors”); and provided further that, in such event, if the number of Continuing Directors shall be reduced below two (2) for any reason whatsoever, the Company Board shall cause the Person(s) designated by the remaining Continuing Director(s) to fill such vacancy(ies), and such person(s) shall be deemed to be a Continuing Director(s) for purposes of this Agreement or, if no Continuing Directors then remain, the other directors of the Company then in office shall designate two (2) persons to fill such vacancies who are not officers, employees, stockholders or Affiliates of the Company, Parent, Merger Sub or any other Subsidiary of Parent, and such persons shall be deemed to be Continuing Directors for purposes of this Agreement. In connection with the foregoing, the Company shall either increase the size of the Company Board or obtain the resignation of such number of its current directors, or both, as is necessary to enable Merger Sub’s designees to be elected or appointed to the Company Board as provided above, and the Company shall take all actions available to the Company to cause Merger Sub’s designees to be so elected or appointed (the date on which the majority of the Company’s directors are designees of Merger Sub that have been effectively appointed to the Company Board in accordance herewith, the “Board Appointment Date”). The parties hereto acknowledge and agree that, from and after the Acceptance Time and for so long as Parent, Merger Sub and any Subsidiary of Parent or Merger Sub (excluding the Company) own at least a majority of the issued and outstanding shares of the

Company Common Stock, the Company shall be a “controlled company” (within the meaning of the listing requirements of the Nasdaq Global Market).

(b) The Company’s obligations to appoint designees of Merger Sub to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-l promulgated thereunder and to the then applicable rules and regulations of The NASDAQ Stock Market LLC. The Company, at its expense, shall promptly take all actions required pursuant to Section 14(f) and Rule 14f-l in order to fulfill its obligations under this Section 1.3, including mailing to the Company’s stockholders the information required by such Section 14(f) and Rule 14f-1 (which the Company shall mail together with the Schedule 14D-9, as contemplated by Section 1.2(b)) as is necessary to fulfill the Company’s obligations under Section 1.3(a); provided, that Parent and Merger Sub shall have timely supplied to the Company in writing, and shall be solely responsible for, any information with respect to Parent, Merger Sub and their designees, officers, directors and Affiliates to the extent required by such Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The provisions of Section 1.3(a) are in addition to and shall not limit any rights Parent, Merger Sub or any of their Affiliates may have as a holder or beneficial owner of Shares as a matter of law with respect to the election of directors or otherwise; provided, however, that in no event shall Parent, Merger Sub or any of their Affiliates take any action prior to the Effective Time to remove any Continuing Director from the Company Board other than for cause.

(c) Following the election or appointment of Merger Sub’s designees pursuant to Section 1.3(a) and prior to the Effective Time, the approval by a majority of the Continuing Directors then in office (or, if there shall be only one or two Continuing Directors then in office, all of such Continuing Directors then in office) shall be required to authorize (and such authorization shall (A) not be effective unless there is in office at least one (1) Continuing Director and (B) constitute the authorization of the Company Board, and no other action on the part of the Company, including any action by any committee thereof or any other director of the Company, shall, unless otherwise required by Law, be required or permitted to authorize) (i) any amendment, modification or termination of this Agreement by the Company, (ii) any extension of time for performance of any obligation or action hereunder by Parent or Merger Sub, (iii) any waiver or exercise of any of the Company’s rights under this Agreement, (iv) any waiver of any condition to the Company’s obligations hereunder, (v) any amendment to the Company’s certificate of incorporation or bylaws, (vi) any authorization of any agreement between the Company, on the one hand, and Parent, Merger Sub or any of their Affiliates, on the other hand, or (vii) the taking of any other action by the Company in connection with this Agreement or the Transactions, other than (A) the Company’s performance of its obligations under this Agreement, including the consummation of the Merger, and (B) other actions that could not reasonably be expected to adversely affect the interests of the stockholders of the Company (other than Parent or any of its Affiliates). The Continuing Directors shall have the authority to retain such counsel (which may include current counsel to the Company) and other advisors at the expense of the Company as determined by the Continuing Directors and shall have the authority to institute any action on behalf of the Company to enforce performance of this Agreement or any of the Company’s rights hereunder.

Section 1.4. Option to Acquire Additional Shares.

(a) The Company hereby grants to Merger Sub an option (the “Top-Up Option”), exercisable in accordance with this Section 1.4, to purchase the number of shares of Company Common Stock (the “Top-Up Option Shares”) equal to the number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock owned in the aggregate by Parent, Merger Sub and any Subsidiary of Parent or Merger Sub immediately prior to the exercise of the Top-Up Option (including all Shares validly tendered and not properly withdrawn in the Offer at the Acceptance Time), shall constitute 5,000 shares more than 90% of the number of shares of Company Common Stock then outstanding (after giving effect to the issuance of the Top-Up Option Shares) for a purchase price per Top-Up Option Share equal to the Offer Price. The Top-Up Option shall only be exercised one time by Merger Sub in whole but not in part.

(b) In no event shall the Top-Up Option be exercisable for a number of shares of Company Common Stock in excess of the Company’s then authorized and unissued shares of Company Common Stock (including as authorized and unissued shares of Company Common Stock, for purposes of this Section 1.4, any shares of Company Common Stock held in the treasury of the Company and any shares of Company Common Stock reserved for issuance upon the exercise of any Company Securities).

(c) The Top-Up Option shall be exercised by Merger Sub (and Parent shall cause Merger Sub to exercise the Top-Up Option) promptly (but in any event within one (1) Business Day) following the Acceptance Time or the expiration of any Subsequent Offering Period, as applicable, if (i) at the Acceptance Time or expiration of a Subsequent Offering Period, as applicable, Parent, Merger Sub and any Subsidiary of Parent or Merger Sub do not own in the aggregate at least 90% of the number of shares of Company Common Stock then outstanding and (ii) after giving effect to the exercise of the Top-Up Option, and taking into account the limitations set forth in Section 1.4(b), Parent, Merger Sub and any Subsidiary of Parent or Merger Sub would own in the aggregate at least 5,000 shares more than 90% of the number of shares of Company Common Stock then outstanding (after giving effect to the issuance of the Top-Up Option Shares). The obligation of the Company to issue and deliver Top-Up Option Shares upon the exercise of the Top-Up Option is subject to the conditions, unless waived by the Company, that (A) no provision of any applicable Law, and no temporary restraining order, preliminary or permanent injunction or other judgment or order issued by a court of competent jurisdiction or other Governmental Authority of competent jurisdiction, shall prohibit the exercise of the Top-Up Option or the issuance and delivery of the Top-Up Option Shares in respect of such exercise, (B) upon exercise of the Top-Up Option, the number of Shares owned in the aggregate by Parent, Merger Sub and any Subsidiary of Parent or Merger Sub constitutes at least 5,000 shares more than 90% of the number of shares of Company Common Stock that will be outstanding immediately after the issuance of the Top-Up Option Shares, (C) Merger Sub has accepted for payment and paid for all Shares validly tendered in the Offer (including, if applicable, during a Subsequent Offering Period) and not properly withdrawn and (D) upon exercise of the Top-Up Option, Parent covenants to cause the Closing to occur as promptly as practicable following the issuance of the Top-Up Option Shares. Notwithstanding anything to the contrary in this Agreement, the Top-Up Option shall terminate concurrently with any termination of this Agreement. Upon Parent’s written request, the Company shall use its

commercially reasonable efforts to cause its transfer agent to certify in writing to Parent the number of shares of Company Common Stock issued and outstanding as of immediately prior to the exercise of the Top-Up Option after giving effect to the issuance of the Top-Up Option Shares. Subject to the terms and conditions this Agreement, and for so long as this Agreement has not been terminated pursuant to Section 8.1, the Company agrees that it shall maintain out of its existing authorized capital, free from preemptive rights, sufficient authorized but unissued shares of Company Common Stock issuable pursuant to this Agreement so that the Top-Up Option may be exercised (and, for these purposes, no shares of Company Common Stock shall be deemed reserved for issuance pursuant to any other then outstanding Company Securities).

(d) The parties shall cooperate to ensure that the issuance of the Top-Up Option Shares is accomplished in a manner consistent with all applicable Laws, including compliance with an applicable exemption from registration of the Top-Up Option Shares under the Securities Act. If Merger Sub is required to exercise the Top-Up Option, Merger Sub shall give the Company written notice thereof (the “Top-Up Notice”) specifying (i) a place and time for the closing of such purchase (which, subject to applicable Law and any required regulatory approvals, shall be effected as promptly as practicable and not more than three (3) Business Days after the date of delivery of such Top-Up Notice), (ii) the number of shares of Company Common Stock that will constitute the Top-Up Option Shares and (iii) the manner in which Parent or Merger Sub shall pay the applicable purchase price in respect of the Top-Up Option Shares. At the closing of the purchase of the Top-Up Option Shares, (A) the purchase price in respect of the Top-Up Option Shares purchased upon such exercise of the Top-Up Option (which shall equal the product of (x) the number of Top-Up Option Shares being purchased pursuant to the Top-Up Option and (y) the Offer Price) shall be paid to the Company, at Merger Sub’s election, either (I) in immediately available funds by wire transfer to an account designated by the Company or (II) by paying in cash an amount equal to not less than the aggregate par value of such Top-Up Option Shares and by delivering Merger Sub’s unsecured, non-negotiable, non-transferable promissory note in the form attached hereto as Exhibit B (the “Promissory Note”) and in the principal amount of the balance of such purchase price, and (B) the Company shall deliver to Merger Sub a certificate or certificates representing the number of Top-Up Option Shares so purchased.

(e) Parent and Merger Sub acknowledge that the Top-Up Option Shares that Merger Sub may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act, and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Merger Sub agrees that the Top-Up Option and the Top-Up Option Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Merger Sub for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof in violation of the Securities Act. Parent and Merger Sub represent and warrant to the Company that Merger Sub is, or will be upon the purchase of the Top-Up Option Shares, an “accredited investor”, as defined in Rule 501 of Regulation D under the Securities Act. Any certificates evidencing the Top-Up Option Shares shall include any legends required by applicable securities Laws.

ARTICLE 2.

Subject to the terms and conditions of this Agreement and in compliance with the DGCL, at the Effective Time, Merger Sub shall be merged with and into the Company, the separate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation. For purposes of this Agreement, (a) the corporation surviving the Merger after the Effective Time is sometimes referred to as the “Surviving Corporation” and (b) the Company and Merger Sub are collectively referred to as the “Constituent Corporations”.

Section 2.2. Merger Closing.

(a) The Merger shall be consummated (the “Closing”) at 10:00 a.m. (Eastern time) on a date to be specified by the parties, which shall be no later than the second (2nd) Business Day after satisfaction or (to the extent permitted by applicable Law) waiver of the conditions set forth in Article 7 (other than any such conditions that by their nature cannot be satisfied until the Closing Date, which shall be required to be so satisfied or (to the extent permitted by applicable Law) waived on the Closing Date), at the offices of Xxxxxxx Xxxx & Xxxxxxxxx LLP, 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, unless another time, date or place is agreed to in writing by the parties hereto (such date upon which the Closing occurs, the “Closing Date”).

(b) At the Closing, the parties hereto shall cause the Merger to be consummated by causing to be filed with the Secretary of State of the State of Delaware a certificate of merger or a certificate of ownership and merger, as the case may be (in any such case, the “Certificate of Merger”), in such form as required by, and executed in accordance with, the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such later time as Parent and the Company shall agree and specify in the Certificate of Merger (the time the Merger becomes effective being the “Effective Time”).

(c) Notwithstanding anything herein to the contrary, in the event that Parent, Merger Sub and their respective Subsidiaries collectively hold or acquire at least 90% of the outstanding shares of Company Common Stock after giving effect to the closing of the Offer and, if applicable, the purchase by Merger Sub of the Top-Up Shares, Parent and the Company hereby agree to take all necessary and appropriate action to cause the Merger to become effective, without a meeting of the holders of shares of Company Common Stock, in accordance with Section 253 of the DGCL as promptly as practicable.

Section 2.3. Effect of Merger; Organizational Documents; Directors and Officers.

(a) The Merger shall have the effects set forth in this Agreement and Section 259 of the DGCL.

(b) The certificate of incorporation of the Surviving Corporation shall at the Effective Time be amended in its entirety to read as set forth on Exhibit C, until thereafter amended as provided therein and under the DGCL. In addition, subject to Section 6.9 hereof, Parent shall cause the bylaws of the Surviving Corporation to be amended and restated in their entirety so that, immediately following the Effective Time, they are identical to the bylaws of Merger Sub as in effect immediately prior to the Effective Time, except that all references to the name of Merger Sub therein shall be changed to refer to the name of the Company, and, as so amended and restated, such bylaws shall be the bylaws of the Surviving Corporation, until further amended in accordance with the DGCL. The directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation and shall serve until the earlier of their resignation or removal or their respective successors are duly elected or appointed and qualified, as the case may be. The officers of Merger Sub immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation and shall serve until the earlier of their resignation or removal or until their respective successors have been duly elected or appointed and qualified, as the case may be.

Section 2.4. Conversion of Merger Sub Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or any holder of shares of Merger Sub capital stock, each share of Merger Sub capital stock shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

Section 2.5. 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 any holder of Shares the following shall occur:

(a) Each Share issued and outstanding immediately prior to the Effective Time (other than (i) any Shares to be canceled pursuant to Section 2.5(b) and (ii) any Appraisal Shares) shall at the Effective Time be canceled and converted automatically into the right to receive an amount in cash equal to the Offer Price (the “Merger Consideration”). As of the Effective Time, all such Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate, or evidence of shares held in book-entry form, that immediately prior to the Effective Time represented any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration upon surrender of such certificate in accordance with Section 2.7, without interest.

(b) Each Share held in the treasury of the Company and each Share owned by Merger Sub, Parent or any direct or indirect Subsidiary of Parent or of the Company immediately prior to the Effective Time shall be cancelled automatically and retired and shall cease to exist and no payment or distribution shall be made with respect thereto.

(c) The Merger Consideration shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time.

Section 2.6. Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, Shares that are outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand and properly demands appraisal of such Shares (“Appraisal Shares”) pursuant to, and who complies in all respects with, Section 262 of the DGCL (“Section 262”) shall not be converted into the right to receive Merger Consideration as provided in Section 2.5(a), but rather the holders of Appraisal Shares shall be entitled to payment of the fair value of such Appraisal Shares in accordance with Section 262 (and at the Effective Time, such Appraisal Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holders shall cease to have any right with respect thereto, except the right to receive the fair value of such Appraisal Shares in accordance with Section 262); provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, Merger Consideration as provided in Section 2.5(a). The Company shall promptly notify Parent in writing of any written demands received by the Company for appraisal of any Shares, and Parent shall have the right to participate in, and following the Acceptance Time to direct, all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands or approve any withdrawal of any such demands, or agree to do any of the foregoing. Any portion of the Merger Consideration provided to the Exchange Agent pursuant to Section 2.7(a) to pay for Shares that are instead paid fair value in an appraisal proceeding pursuant to Section 262 shall be returned to Parent upon demand. Notwithstanding anything to the contrary contained herein, each of Parent, Merger Sub and the Company agree and acknowledge that in any appraisal proceeding under Section 262 with respect to the Appraisal Shares and to the fullest extent permitted by applicable Law, the Surviving Corporation shall not assert that the Top-Up Option, the Top-Up Option Shares or any cash or Promissory Note delivered by Merger Sub to the Company in payment for such Top-Up Option Shares should be considered in connection with the determination of the fair value of the Appraisal Shares in accordance with Section 262.

Section 2.7. Exchange of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Parent shall enter into an agreement with the Company’s transfer agent on the date of this Agreement, or another bank or trust company selected by Parent and approved in advance by the Company (such approval not to be unreasonably withheld) (the “Exchange Agent”), which shall provide for the payment of Merger Consideration in accordance with the terms of this Article 2. Parent shall, or shall take all steps necessary to enable and cause Merger Sub to, deposit with the Exchange Agent at or prior to the Effective Time, for the benefit of the holders of Shares outstanding immediately prior to the Effective Time, for payment by the Exchange Agent in accordance with this Article 2, the cash in U.S. dollars necessary to pay for the Shares converted into the right to receive Merger Consideration (the “Exchange Fund”). The Exchange Fund shall not be used for any other purpose. The Exchange Fund shall, pending its disbursement to such holders, be invested by the Exchange Agent as directed by Parent; provided, however, 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 Xxxxx’x Investor Service, Inc. or Standard & Poor’s Corporation,

respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $10 billion (based on the most recent financial statements of such bank which are then publicly available); provided further, however, that no gain or loss thereon shall affect the amounts payable to holders of Shares following the Effective Time and Parent shall take all actions necessary to ensure that the Exchange Fund includes at all times cash in U.S. dollars sufficient to satisfy Parent’s obligation under this Article 2. Any interest or income produced (net of any loss) by such amounts on deposit with the Exchange Agent will be payable to Parent or as Parent otherwise directs. In the event of any losses to the Exchange Fund from any investment such that the Exchange Fund is diminished below the level required for the Exchange Agent to make prompt cash payments as required under Section 2.7(b), Parent shall, or shall cause the Surviving Corporation to, as promptly as practicable deposit additional cash into the Exchange Fund to the extent necessary to reimburse the Exchange Fund for any such investment losses.

(b) Exchange Procedures. As soon as reasonably practicable (and in any event within three (3) Business Days) after the Effective Time, Parent shall cause the Exchange Agent to mail to each Person who was a holder of record of Shares immediately prior to the Effective Time, whose Shares were converted into the right to receive the Merger Consideration pursuant to Section 2.5, (i) the form of letter of transmittal for use in effecting the surrender of stock certificates that immediately prior to the Effective Time represented Shares (each, a “Certificate”) or non-certificated Shares represented by book-entry (“Book-Entry Shares”) (which transmittal letter shall be in customary form approved by the Company (such approval not to be unreasonably withheld, delayed or conditioned) and shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in surrendering the Certificates or Book-Entry Shares in exchange for the Merger Consideration. Upon surrender of a Certificate or a Book-Entry Share for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to be paid promptly in exchange therefor, and Parent shall cause the Exchange Agent to pay to such holder, the Merger Consideration in respect of the Shares previously represented by such Certificate or Book-Entry Share, and the Certificate or Book-Entry Shares so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, payment of the Merger Consideration in exchange therefor may be made to a Person other than the Person in whose name the Certificate so surrendered is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such Tax has been paid or is not applicable. Each Certificate and Book-Entry Share shall be deemed at all times from and after the Effective Time to represent only the right to receive upon surrender in accordance with this Section 2.7 the Merger Consideration in respect of the Shares previously represented by such Certificate or Book-Entry Share. No interest shall be paid or shall accrue on any cash payable to holders of Certificates or Book Entry Shares pursuant to the provisions of this Article 2.

(c) No Further Ownership Rights in Shares. The Merger Consideration paid upon the surrender of Certificates and Book Entry Shares in accordance with the terms of this Article 2 shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares previously represented by such Certificates and Book Entry Shares. From and after the Effective Time, the Surviving Corporation shall not permit any further registration of transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book Entry Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article 2, except as otherwise required by Law.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares for 180 days after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Certificates or Book Entry Shares who have not theretofore complied with this Article 2 shall thereafter only be entitled to receive from the Surviving Corporation (subject to abandoned property, escheat or similar Laws, as general creditors thereof) payment of their claim for Merger Consideration. Any amounts remaining unclaimed immediately prior to such time when such amounts would otherwise escheat or become the property of any Governmental Authority, 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) No Liability. Except to the extent prohibited by applicable Law, none of Parent, Merger Sub, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any holder of a Certificate or Book Entry Share for any Merger Consideration that is delivered to a public official pursuant to any abandoned property, escheat or other similar Law.

(f) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact in form and substance reasonably satisfactory to Parent by the Person claiming such Certificate to be lost, stolen or destroyed and, if requested by Parent or the Exchange Agent, the posting by such Person of a bond in such reasonable amount as Parent or the Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto pursuant to this Agreement.

Section 2.8. Equity-Based Compensation Plans and Awards.

(a) Prior to the Acceptance Time, the Company shall take all reasonable steps necessary to provide that each Option, whether vested or unvested, that is outstanding immediately prior to the Acceptance Time shall become fully vested immediately prior to the Acceptance Time, and be cancelled as of the Acceptance Time (without regard to the exercise price of such Option) in exchange for the right to receive at such time, without interest, in accordance with this Section 2.8(a), a lump sum cash payment in the amount of the Option Consideration (net of applicable taxes in accordance with Section 2.9), if any, with respect to such Option. In the event that the aggregate exercise price of any Option is equal to or greater than the Offer Price multiplied by the number of shares of Company Common Stock issuable under such Option, such Option shall be cancelled, without any consideration being payable in

respect thereof, and have no further force or effect. Following the Acceptance Time, no Option shall remain outstanding and all holders of an Option that was outstanding immediately prior to the Acceptance Time shall only be entitled to receive the consideration (if any) set forth in this Section 2.8(a). The Company shall pay any amounts payable to holders of Options as promptly as practicable after the Acceptance Time, and in no event later than the first regular payroll cycle following the Acceptance Time.

(b) Prior to the Acceptance Time, the Company shall take all reasonable steps necessary to provide that each Restricted Stock Unit, whether vested or unvested, that is outstanding immediately prior to the Acceptance Time shall become fully vested and all restrictions and conditions applicable thereto shall lapse immediately prior to the Acceptance Time and be cancelled as of the Acceptance Time and converted into the right to receive, without interest, a cash payment equal to the Offer Price. Following the Acceptance Time, no Restricted Stock Unit shall remain outstanding and all holders of a Restricted Stock Unit that was outstanding immediately prior to the Acceptance Time shall only be entitled to receive the consideration set forth in this Section 2.8(b).

(c) Each holder of Restricted Stock Units shall receive from the Company or the Surviving Corporation, as applicable, in respect of and in consideration thereof, as promptly as practicable after the Acceptance Time and in no event later than the first regular payroll cycle following the Acceptance Time, an amount (net of applicable taxes in accordance with Section 2.9) equal to the consideration payable under this Section 2.8, as applicable.

(d) Prior to the Acceptance Time, the Company Board (or, if appropriate, any committee thereof administrating the Stock Plan) shall adopt such resolutions as may be required to effectuate the provisions of this Section 2.8.

(e) For the avoidance of doubt, the Company does not make any representation or warranty with respect to the matters set forth in this Section 2.8.

Section 2.9. Withholding Rights. Parent, Merger Sub and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, whether to any holder of Shares or pursuant to Section 2.8, such amounts as Parent, Merger Sub or the Surviving Corporation is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law. To the extent that such amounts are so withheld by Parent, Merger Sub or the Surviving Corporation, such withheld and deducted amounts will be paid to the applicable Governmental Authority and treated for all purposes of this Agreement as having been paid to the holders of Shares, Options and Restricted Stock Units, as the case may be, in respect of which such deduction and withholding was made by Parent, Merger Sub or the Surviving Corporation.

Section 2.10. Further Action. If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any further deeds, assignments or assurances in law or any other acts are necessary or desirable to (a) 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 the Company or (b) otherwise carry out the provisions of this

Agreement, the Company and its officers and directors shall be deemed to have granted to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such deeds, assignments or assurances in law and to take all acts necessary, proper or desirable to vest, perfect or confirm title to and possession of such rights, properties or assets in the Surviving Corporation and otherwise to carry out the provisions of this Agreement, and the officers and directors of the Surviving Corporation are authorized in the name of the Company or otherwise to take any and all such action.

No additional investigations or disclosures shall affect the Company’s representations and warranties contained herein, or limit or otherwise affect the remedies available to Parent and Merger Sub pursuant to this Agreement.

(b) Until the Board Appointment Time, the provisions of the Confidentiality Agreement dated February 23, 2011 between Merck Sharp & Dohme Corp. and the Company (the “Confidentiality Agreement”) shall remain in full force and effect in accordance with its terms, other than paragraph 11 thereof as it relates to this Agreement and the Transactions.

Section 6.8. No Solicitation.

(a) The Company has, and each of its Representatives have, ceased and caused to be terminated any solicitation, encouragement, discussion or negotiation with any Third Parties that commenced prior to the date of this Agreement with respect to a Takeover Proposal. From and after the date hereof until the earlier of the Acceptance Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, except as expressly permitted by this Section 6.8, the Company shall not, and shall direct each of its directors, officers, employees, consultants, advisors (including, without limitation, attorneys, accountants, investment bankers and financial advisors), agents and other representatives (collectively, “Representatives”) not to, directly or indirectly, (i) solicit, initiate, knowingly encourage or knowingly facilitate the submission of any Takeover Proposal, (ii) participate or engage in any discussions or negotiations with, or furnish any non-public information to, any Third Party in connection with, or for the purposes of encouraging or facilitating, a Takeover Proposal, (iii) approve, endorse, recommend or enter into, or publicly propose to approve, endorse, recommend or enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement (other than an Acceptable Confidentiality Agreement (as defined below) in accordance with Section 6.8(b) below) relating

to or providing for a Takeover Proposal (an “Alternative Acquisition Agreement”) or (iv) take any other action designed to, or that would knowingly facilitate, the making or receipt of any Takeover Proposal or the consummation thereof. The Company shall be deemed to be in breach of the provisions of this Section 6.8 upon the breach of any such provisions by the Company’s Representatives.

(b) Notwithstanding anything to the contrary contained in Section 6.8(a) or any other provision of this Agreement, at any time after the date hereof and prior to the earlier of the Acceptance Time and the date, if any, on which this Agreement is terminated pursuant to Section 8.1, the Company, directly or indirectly through its Representatives, may, subject to compliance with this Section 6.8, (i) furnish non-public information to any Third Party that has submitted a Takeover Proposal (provided, that (A) prior to so furnishing such information, the Company receives from the Third Party an executed confidentiality agreement containing terms no less favorable to the Company in any material respect (other than any standstill provision, which shall be no less favorable to the Company in any respect) than the terms set forth in the Confidentiality Agreement (an “Acceptable Confidentiality Agreement”), and (B) any material non-public information concerning the Company provided to any Third Party given such access shall, to the extent not previously provided to Parent or Merger Sub, be provided to Parent or Merger Sub at substantially the same time it is provided to such Third Party), (ii) contact any Third Party that has submitted a Takeover Proposal solely to clarify the terms and conditions of such Takeover Proposal, and (iii) engage in discussions or negotiations with, and take any other actions referred to clauses (i) or (ii) of Section 6.8(a) with respect to, the Takeover Proposal submitted by such Third Party if, in the case of clause (i) and clause (iii) immediately above, such Third Party has submitted a Takeover Proposal which the Company Board determines in good faith, after consultation with its financial and legal advisors, constitutes, or is reasonably likely to lead to, a Superior Proposal. Prior to taking any of the actions referred to in clause (i) or clause (iii) of this Section 6.8(b), the Company shall notify Parent and Merger Sub orally and in writing that it proposes to furnish non-public information and/or enter into discussions or negotiations as provided in this Section 6.8(b).

(c) Except as permitted by this Section 6.8(c) or Section 6.8(d), neither the Company Board nor any committee thereof shall (i) withhold, withdraw (or not continue to make), change, amend or modify in a manner adverse to Parent or Merger Sub, or publicly propose to withhold, withdraw (or not continue to make), change, amend or modify, in a manner adverse to Parent or Merger Sub, the Board Recommendation; (ii) if a tender offer or exchange offer for shares of capital stock of the Company that constitutes a Takeover Proposal is commenced, fail to recommend against acceptance of such tender offer or exchange offer by the stockholders of the Company (including, for these purposes, by taking no position with respect to the acceptance of such tender offer or exchange offer by the stockholders of the Company, which shall constitute a failure to recommend against acceptance of such tender offer or exchange offer) within ten (10) Business Days after commencement thereof, or (iii) approve or recommend, or publicly propose to approve or recommend any Takeover Proposal made or received after the date hereof (any of the actions described in clauses (i) through (iii) of this Section 6.8(c), a “Company Adverse Recommendation Change”), or (iv) cause or permit the Company to enter into any Alternative Acquisition Agreement. Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to the Acceptance Time, the Company Board shall be permitted, (x) subject to compliance with Section 6.8 and the concurrent payment

of any amount owed the Company pursuant to Section 8.3, in response to an unsolicited Takeover Proposal made after the date hereof, to terminate this Agreement to concurrently enter into a definitive agreement with respect to a Superior Proposal if the Company Board (A) has received a Takeover Proposal that, in the good faith determination of the Company Board, constitutes a Superior Proposal, after having complied with, and giving effect to all of the adjustments which may be offered by Parent and Merger Sub pursuant to, Section 6.8(d), (B) determines in good faith, after consultation with its financial and legal advisors, that failure to take such action would reasonably be likely to violate the directors’ fiduciary duties under applicable Law and (C) provides to Parent the most current version of the proposed agreement under which the Superior Proposal is proposed to be consummated, or (y) subject to compliance with Section 6.8, to effect a Company Adverse Recommendation Change described in clause (i) of such definition, in response to a material fact, event, change, development or set of circumstances (other than a Takeover Proposal) occurring or arising after the date of this Agreement that was not known by the Company Board as of or prior to the date of this Agreement (and not relating in any way to any Takeover Proposal) (such material fact, event, change, development or set of circumstances, an “Intervening Event”), if the Company Board determines in good faith, after consultation with outside legal counsel, that, in light of such Intervening Event, the failure of the Company Board to effect such a Company Adverse Recommendation Change would reasonably be likely to violate the directors’ fiduciary duties under applicable Law; provided, however, that the Company shall not be entitled to exercise its right to make a Company Adverse Recommendation Change pursuant to this clause (y) unless the Company has (A) provided to Parent at least three (3) Business Days’ prior written notice advising Parent that the Company Board intends to take such action and specifying the facts underlying the Company Board’s determination that an Intervening Event has occurred, and the reasons for the Company Adverse Recommendation Change, in reasonable detail, and (B) during such three (3) Business Day period, if requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner that obviates the need for a Company Adverse Recommendation Change as a result of the Intervening Event.

(d) The Company shall not be entitled to effect a Company Adverse Recommendation Change or to terminate this Agreement as permitted under Section 6.8(c), in each case, with respect to a Superior Proposal unless (i) the Company has provided a written notice (a “Notice of Superior Proposal”) to Parent and Merger Sub that the Company intends to take such action that includes the material terms of the Superior Proposal that is the basis of such action (including the identity of the Third Party making the Superior Proposal), (ii) during the four (4) Business Day period following Parent’s and Merger Sub’s receipt of the Notice of Superior Proposal, the Company shall, and shall direct its Representatives to, negotiate with Parent and Merger Sub in good faith (to the extent Parent and Merger Sub desire to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute a Superior Proposal, and (iii) following the end of such four (4) Business Day period, the Company Board shall have determined in good faith, taking into account any changes to this Agreement proposed in writing by Parent and Merger Sub, that the Superior Proposal giving rise to the Notice of Superior Proposal continues to constitute a Superior Proposal. Any material amendment to the financial terms or any other material amendment of such Superior Proposal shall require a new Notice of Superior Proposal and the Company shall be required to comply again with the requirements of this Section 6.8(d);

provided, however, that references to the four (4) Business Day period above shall be deemed to be references to a two (2) Business Day period.

(e) From and after the date hereof, the Company shall, as promptly as reasonably practicable (and in any event within one (1) Business Day), provide Parent and Merger Sub a copy of all draft agreements (and any other written material to the extent such material contains any financial terms, conditions or other material terms relating to any Takeover Proposal or, where no such written materials are available, a reasonably detailed description of such Takeover Proposal) or any request for non-public information in connection with any Takeover Proposal (including the identity of the Person or group making the Takeover Proposal or request, as applicable), and shall keep Parent and Merger Sub reasonably informed of the status of any such Takeover Proposal or request on a reasonably current basis (and in any event at Parent’s request and otherwise within one (1) Business Day after the occurrence of any material amendments, developments, discussions or negotiations) and provide to Parent as promptly as reasonably practicable (and in any event within one (1) Business Day after receipt or delivery thereof), copies of all other written inquiries or correspondence sent by or provided to the Company (or its Representatives) in connection with any such Takeover Proposal or request.

(f) Nothing contained in this Agreement shall prohibit the Company or the Company Board, directly or indirectly through its Representatives, from (i) taking and disclosing to the Company’s stockholders a position with respect to a tender or exchange offer by a Third Party pursuant to Rule 14d-9, Rule 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (or any similar communication to the Company’s stockholders), or (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 any similar communication to the Company’s stockholders) if the Company Board has determined in good faith, after consultation with legal counsel, that the failure to do so is reasonably likely to violate its fiduciary duties under applicable Law; provided that the taking of any such position or making of any such disclosure pursuant to clause (i) immediately above shall be subject to and only taken in compliance with Section 6.8(c) and provided, further that any such disclosure or communication pursuant to clause (i) immediately above other than, or which is not accompanied by, (x) an express rejection of any applicable Takeover Proposal or (y) an express reaffirmation of the Board Recommendation, shall be deemed to be a Company Adverse Recommendation Change.

Section 6.9. Indemnification and Insurance.

(a) Parent and Merger Sub agree that all rights to advancement of expenses, indemnification and exculpation by the Company now existing in favor of each person who is now, or has been at any time prior to the date of this Agreement or who becomes prior to the Effective Time, an officer or director of the Company (each, together with such person’s heirs, executors or administrators, an “Indemnified Party”) as provided in the Company’s certificate of incorporation or bylaws, in each case as in effect on the date of this Agreement, or pursuant to any other agreements in effect on the date of this Agreement which have been provided to Parent prior to the date hereof, shall survive the Merger from the Effective Time through the sixth (6th) anniversary of the date on which the Effective Time occurs.

(b) From and after the Acceptance Time, each of Parent and the Surviving Corporation shall, jointly and severally, to the fullest extent permitted under applicable Law, indemnify, defend and hold harmless (and advance funds in respect of each of the foregoing, subject to the indemnifying or advancing party’s receipt of an unsecured undertaking by or on behalf of the Indemnified Party to repay such funds if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Party is not entitled to indemnification hereunder) each Indemnified Party against any costs or expenses (including advancing reasonable attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by Law), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (an “Action”), arising out of, relating to or in connection with any Action or omission occurring or alleged to have occurred whether before or after the Acceptance Time in connection with such Indemnified Party serving as an officer or director of the Company or any entity if such service was at the request or for the benefit of the Company.

(c) Parent shall cause the Surviving Corporation, as of the Effective Time, to cause the individuals who have served as officers and directors of the Company prior to the Effective Time who are then covered by the directors’ and officers’ liability insurance policy currently maintained by the Company (the “D&O Insurance”), to be covered under a prepaid directors’ and officers’ liability insurance policy on terms and conditions no less advantageous to such individuals than the Company’s existing directors’ and officers’ liability insurance policy, for a period of not less than six (6) years after the Effective Time, but only to the extent related to actions or omissions of such officers and directors at or prior to the Effective Time (including in respect of this Agreement and the Transactions) in their capacities as such, whether asserted or claimed prior to, at or after the Effective Time; provided, that in no event shall the Surviving Corporation be required to expend more than an amount per year equal to 300% of current annual premiums paid by the Company for such insurance (the “Maximum Amount”) to maintain or procure insurance coverage pursuant hereto; provided, further, that if the amount of the annual premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, the Surviving Corporation shall procure and maintain for such six-year (6) period as much coverage as is available for the Maximum Amount. Parent shall have the right to cause coverage to be extended under the D&O Insurance by causing the Surviving Corporation to obtain a six (6) year “tail” policy on terms and conditions no less advantageous to such former directors or officers than the D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 6.9(c). Notwithstanding anything to the contrary in this Agreement, the Company may, prior to the Effective Time, purchase a so-called “Reporting Tail Endorsement,” provided that the Company does not pay more than the amount set forth in Section 6.9(c) of the Company Disclosure Letter for such Reporting Tail Endorsement, in which case, provided that Parent causes the Surviving Corporation to maintain such Reporting Tail Endorsement in full force and effect for its full term, Parent shall be relieved from its obligations under this Section 6.9(c).

(d) 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 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 Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 6.9.

(e) The obligations of Parent and the Surviving Corporation under this Section 6.9 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 6.9 applies without the written consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 6.9 applies shall be third party beneficiaries of this Section 6.9, each of whom may enforce the provisions of this Section 6.9). Parent shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in connection with their enforcement of their rights provided in this Section 6.9; provided that such Indemnified Party prevails in such enforcement action.

(f) The provisions of this Section 6.9 are intended to be in addition to the rights otherwise available to the current and former officers and directors of the Company by law, charter, statute, bylaw or agreement.

Section 6.10. Section 16 Matters. Prior to the Acceptance Time, the Company shall take all such steps as may be required to cause the transactions contemplated by Section 2.8 and any other dispositions of equity securities of the Company (including derivative securities) in connection with this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 under the Exchange Act (in accordance with that certain SEC No-Action Letter to Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP, dated January 12, 1999 issued by the SEC regarding such matters).

Section 6.11. Rule 14d-10(d). Prior to the Acceptance Time and to the extent permitted by Law, the Company (acting through its Compensation Committee or its independent directors, to the extent required) shall take all such steps as may be required to cause each employment compensation, severance and employee benefit agreement, arrangement or understanding entered into by the Company on or after the date of this Agreement with any of its officers, directors or employees pursuant to which consideration is paid to such officers, director or employee to satisfy the requirements of the non-exclusive safe-harbor set forth in Rule 14d-10(d) of the Exchange Act.

Section 6.12. State Takeover Laws. The Company and Parent and their respective Boards of Directors shall (a) use reasonable best efforts to ensure that no state takeover Law or similar Law is or becomes applicable to this Agreement, the Offer, the Merger or any of the other Transactions and (b) if any state takeover Law or similar Law becomes applicable to this Agreement, the Offer, the Merger, the Top-Up Option or any of the other Transactions, use reasonable best efforts to ensure that the Offer, the Merger, the Top-Up Option and the other Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such Law on this Agreement, the Offer, the Merger and the other Transactions. The Company shall not take any action to approve any Takeover Proposal made by any Person other than Parent or any Subsidiary of Parent for purposes of any state takeover Law or to cause any state takeover Law that would otherwise apply to any such Takeover Proposal to become inapplicable thereto,

except to the extent such action is taken immediately prior to or concurrently with the termination of this Agreement by the Company in accordance with Section 8.1(d).

Section 6.13. Stock Exchange De-listing. Prior to the Effective Time, the Company shall cooperate with Parent and use its 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 LLC to enable the de-listing of the common stock of the Surviving Corporation from The NASDAQ Stock Market LLC and the deregistration of such common stock under the Exchange Act as promptly as practicable after the Effective Time.

Section 6.14. Control of Operations. Without in any way limiting any party’s rights or obligations under this Agreement, the parties understand and agree that (a) nothing contained in this Agreement shall give Parent or Merger Sub, directly or indirectly, the right to control or direct the Company’s operations prior to the Board Appointment Date, and (b) prior to the Board Appointment Date, the Company shall exercise, subject to the terms and conditions of this Agreement, complete control and supervision over its operations.

Section 6.15. FIRPTA Certificate. On the Closing Date, the Company shall provide to Parent an affidavit, dated as of the Closing Date, signed under penalty of perjury, and in form and substance required under the Treasury Regulations issued pursuant to Section 1445(f) and Section 897 of the Code, so that Parent is exempt from withholding any portion of the aggregate consideration with respect to the Merger under Section 1445 of the Code.

Section 6.16. Litigation. The Company shall promptly notify Parent of any litigation commenced against it or any of its directors, officers or Affiliates, relating to this Agreement or the Transactions (including the Offer and the Merger) and shall keep Parent reasonably informed regarding any such litigation. The Company shall give Parent the opportunity to participate at its own expense in the defense or settlement of any litigation against the Company and its directors relating to this Agreement and the Transactions, and no such settlement shall be agreed to by the Company without Parent’s prior written consent (not to be unreasonably withheld, conditioned or delayed).

Section 6.17. Obligations of Merger Sub and the Surviving Corporation. Parent shall take all action necessary to cause Merger Sub, the Surviving Corporation and, following the Board Appointment Time, the Company, to perform their respective obligations under this Agreement. Immediately following the execution of this Agreement, Parent shall execute and deliver, in accordance with Section 228 of the DGCL and in its capacity as the sole stockholder of Merger Sub, a written consent adopting this Agreement.

ARTICLE 8.

TERMINATION, AMENDMENT AND WAIVER

(a) by mutual written consent of Parent, Merger Sub and the Company prior to the Acceptance Time; or

(b) by either the Company or Parent as follows:

(i) if the Acceptance Time shall not have occurred on or before 5:00 p.m. New York City time on September 5, 2011 (the “Walk Away Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(i) shall not be available to any party if the failure of the Acceptance Time to occur on or before the Walk Away Date was caused by or resulted from the failure of such party (or any Affiliate of such party) to perform in any material respect any covenant or agreement in this Agreement required to be performed by such party (or any Affiliate of such party); or

(ii) if any Judgment issued by a court of competent jurisdiction or by a Governmental Authority, or Law or other legal restraint or prohibition, in each case making the consummation of the Offer or Merger illegal or permanently restraining, enjoining or otherwise preventing the consummation thereof shall be in effect and shall have become final and nonappealable; provided that the right to terminate this Agreement pursuant to this Section 8.1(b)(ii) shall not be available to any party to this Agreement if the issuance of such Judgment,

Law, legal restraint or prohibition was caused by or resulted from the failure of such party (or any Affiliate of such party) to perform in any material respect any covenant or agreement in this Agreement required to be performed by such party (or any Affiliate of such party); or

(c) by Parent, if (x) there shall have occurred a Company Adverse Recommendation Change, (y) the Company shall have materially breached any of its obligations under Section 6.8, provided that such material breach was the result of actions taken or not taken by, at the direction of or with the consent or knowledge of any member of the Company’s Knowledge group, any member of the Company Board or senior individual employed by the any financial or legal advisor to the Company in connection with the Transactions, or in the case of any other material breach of Section 6.8, such breach became known to any member of the Company’s Knowledge group or any member of the Company Board and the Company failed to use its best efforts to cause such breach to cease to be ongoing, or (z) the Company Board fails publicly to reaffirm its recommendation of this Agreement, the Offer or the Merger (A) within five (5) Business Days of receipt of a written request by Parent or Merger Sub to provide such reaffirmation following a Takeover Proposal that is communicated publicly to the stockholders of the Company (which reaffirmation request may be made by Parent or Merger Sub only once with respect to each Takeover Proposal or any amendment to the financial terms or any other material term of such Takeover Proposal that is communicated publicly to the stockholders of the Company) or (B) if the Acceptance Time is less than five (5) Business Days from the receipt of such request by Parent or Merger Sub, by the close of business on the Business Day immediately preceding the Acceptance Time;

(d) by the Company, if both of the following conditions are satisfied and subject to the Company having not materially breached any of its obligations under Section 6.8: (A) the Company Board prior to or concurrently with such termination approves, and substantially concurrently with such termination enters into, an Alternative Acquisition Agreement providing for a Superior Proposal, to the extent permitted by, and in accordance with, the terms and conditions of Section 6.8(c) and Section 6.8(d); and (B) the Company simultaneously with such termination pays, or causes to be paid, the Termination Fee required by Section 8.3(c) to Parent by wire transfer of immediately available funds;

(e) by Parent prior to the Acceptance Time, if there has been a breach of or failure to perform, as applicable, any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement (other than the covenants or agreements set forth in Section 6.8, in respect of which Section 8.1(c)(y) shall apply), which breach or failure to perform (i) would cause the conditions set forth in clauses 2(b) or 2(c) of Annex A not to be satisfied, and (ii) shall not have been cured prior to the earlier of (x) thirty (30) days following receipt by the Company of written notice of such breach or failure to perform from Parent, or (y) the Walk Away Date; provided, that the right of Parent to terminate this Agreement under this Section 8.1(e) shall not be available to Parent if Parent or Merger Sub is then in breach of any covenant or other agreement set forth in this Agreement which breach would have a Parent Material Adverse Effect;

(f) by the Company prior to the Acceptance Time, if there has been a breach of or failure to perform, as applicable, any representation, warranty, covenant or agreement on the part of Parent or Merger Sub set forth in this Agreement, which breach or failure to perform

shall have had or would reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect and shall not have been cured prior to the earlier of (i) thirty (30) days following receipt by Parent of written notice of such breach or failure to perform from the Company, or (ii) the Walk Away Date; provided, that the right of the Company to terminate this Agreement under this Section 8.1(f) shall not be available to the Company if the Company is then in breach of any covenant or other agreement set forth in this Agreement which would cause the condition set forth in clause 2(c) of Annex A not to be satisfied; or

(g) by the Company, if, for any reason, (i) Merger Sub shall have failed to commence the Offer within the time period specified in the first sentence of Section 1.1(a), (ii) Merger Sub terminates or makes any change to the Offer in material breach of the terms of this Agreement, or (iii) Merger Sub shall have breached its obligation hereunder to purchase all Shares validly tendered and not properly withdrawn as of the initial Expiration Date or any subsequent Expiration Date established in accordance with the terms set forth in this Agreement, provided that the Company shall not be permitted to terminate this Agreement pursuant to the immediately preceding clause (ii) unless the breach referred to therein shall not have been cured prior to earlier of (x) three (3) Business Days following receipt by Parent of written notice of such breach from the Company and (y) five (5) Business Days prior to the Walk Away Date.

For the avoidance of doubt, this Agreement may not be terminated following the Acceptance Time. Except in the case of a termination pursuant to Section 8.1(a), the party desiring to terminate this Agreement shall deliver written notice of such termination to the other party or parties to this Agreement, setting forth in such notice the provision of this Section 8.1 pursuant to which such party is terminating this Agreement.

Section 8.2. Effect of Termination. Upon the termination of this Agreement pursuant to Section 8.1, this Agreement shall forthwith become null and void and of no effect without any liability on the part of any party hereto, and all rights and obligations of any party hereto shall cease and terminate, except for the provisions of (a) this Section 8.2, (b) Section 8.3 (Fees and Expenses), and (c) Article 9 (General Provisions), which shall survive such termination and remain in full force and effect; provided, however, that neither the termination of this Agreement nor anything else contained herein to the contrary, shall relieve any party from any liability or damages that is attributable to fraud or to any willful breach of this Agreement occurring prior to such termination in accordance with the terms set forth herein. The Confidentiality Agreement shall not be affected by the termination of this Agreement and shall continue in full force and effect in accordance with its terms.

Section 8.3. Fees and Expenses.

(a) Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such fees and expenses, whether or not the Offer or the Merger is consummated.

(b) In the event that this Agreement is terminated by (i) Parent pursuant to clause (y) or clause (z) of Section 8.1(c), or (ii) either (x) Parent or the Company pursuant to Section 8.1(b)(i) or (y) Parent pursuant to Section 8.1(e), so long as, in any such case, (A) before the date of such termination, a bona fide Takeover Proposal shall have been publicly announced

or otherwise been publicly communicated to the holders of Company Common Stock, and, in each case, not subsequently publicly withdrawn, and (B) within twelve (12) months after the date of such termination (x) the Company shall have entered into a definitive agreement in respect of any Takeover Proposal and (y) such Takeover Proposal is consummated, then the Company shall pay, or cause to be paid, to Parent by wire transfer of immediately available funds an amount equal to $17,000,000.00 (the “Termination Fee”), such payment to be made no later than the third (3^rd) Business Day following the date of the consummation of such Takeover Proposal; provided, however, that for purposes of this Section 8.3(b)(i), each reference to “20%” in the definition of Takeover Proposal shall be deemed to be a reference to “50%”.

(c) In the event that this Agreement is terminated by (i) Parent pursuant to clause (x) of Section 8.1(c) or (ii) the Company pursuant to Section 8.1(d), then the Company shall pay, or cause to be paid, to Parent by wire transfer of immediately available funds an amount equal to the Termination Fee, such payment to be made (A) in the case of a termination pursuant to the foregoing clause (i), no later that the third (3^rd) Business Day following the date of termination or (B) in the case of a termination pursuant to the foregoing clause (ii), concurrently with such termination.

(d) For the avoidance of doubt, the Company shall not be required to pay a Termination Fee pursuant to more than one clause of this Section 8.3 or on more than one occasion, and that the Termination Fee shall be reduced by any amounts as may be required to be deducted or withheld therefrom pursuant to applicable Tax Law. The parties acknowledge and agree that (i) the agreements contained in this Section 8.3 are an integral part of the Transactions, (ii) the damages resulting from termination of this Agreement under circumstances where a Termination Fee is payable by the Company are uncertain and incapable of accurate calculation and therefore, the amounts payable pursuant to Section 8.3(b) or Section 8.3(c), as applicable, are not a penalty, but rather are liquidated damages in a reasonable amount that will compensate Parent and Merger Sub, as the case may be, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions, which amount would otherwise be impossible to calculate with precision, (iii) without these agreements, Parent and Merger Sub would not enter into this Agreement, and (iv) payment of the Termination Fee pursuant to the applicable provision of this Section 8.3 shall constitute the sole and exclusive remedy of Parent, Merger Sub, any Affiliate thereof or any other Person against the Company and its Affiliates, stockholders, directors, officers, employees or Representatives in connection with any termination of this Agreement pursuant to a provision for which the Termination Fee is payable. Accordingly, if the Company fails timely to pay the Termination Fee when due pursuant to Section 8.3, and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for the Termination Fee, the Company shall pay to Parent its documented and reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the Termination Fee from the date such payment was required to be made until the date of payment at a per annum rate equal to the prime rate of Citibank, N.A., in effect on the date such payment was required to be made, plus two percent (2%).

Section 8.4. Amendment. Subject to Section 1.3(c), at any time prior to the Effective Time, this Agreement may be amended by the parties hereto, by action taken or

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

Section 9.3. Interpretations. When a reference is made in this Agreement to Sections or Exhibits, such reference shall be to a Section or Exhibit to this Agreement unless otherwise indicated. For purposes of this Agreement, (i) the words “include,” “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation”; (ii) “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if”; and (iii) “hereof”, “hereto”, “hereby”, “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement. With respect to the determination of any period of time, the words “from,” “since,” “between” mean “from and including” and the words “to” and “until” each mean “to but excluding.” The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa. Any reference to any federal, state, local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. References to an agreement or instrument mean such agreement or instrument as from time to time amended, modified or supplemented. The parties hereto agree that they have been represented by counsel during the negotiation, drafting, preparation and execution of this Agreement and, therefore, waive the application of any Law or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document. Parent and Merger Sub agree that the Company shall not be deemed to be in breach of its obligations pursuant Section 2.8 in the event (i) any holder of Options and/or Restricted Stock Units alleges that his or her Options and/or Restricted Stock Units were not validly cancelled by the Company or (ii) if any Options or Restricted Stock Units are, or are deemed to be, outstanding following the Acceptance Time.

Section 9.4. Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware without regard to the conflict or choice of laws provisions thereof that would give rise to the application of the domestic substantive law of any other jurisdiction.

Section 9.5. Jurisdiction; Waiver of Jury Trial.

(a) Each of the parties to this Agreement (i) consents to submit itself to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware in any action or proceeding arising out of or relating to this Agreement or any of the Transactions, (ii) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in any such court, (iii) agrees that it shall not attempt to deny or defeat

such personal jurisdiction by motion or other request for leave from any such court, (iv) agrees not to assert as a defense, counterclaim or otherwise 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 judgments, attachments prior to judgment, attachments in advance of execution of judgment, execution of judgment or otherwise), and (v) agrees not to bring any action or proceeding arising out of or relating to this Agreement or any of the Transactions in any other court. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party hereto may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 9.1. Nothing in this Section 9.5(a), however, shall affect the right of any party to serve legal process in any other manner permitted by Law.

(b) EACH OF THE PARTIES TO THIS AGREEMENT IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS.

Section 9.6. Counterparts; Facsimile Transmission of Signatures. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, and delivered by means of facsimile transmission or other electronic transmission, each of which when so executed and delivered shall be deemed to be an original and all of which when taken together shall constitute one and the same agreement. This Agreement may be executed and delivered by facsimile or .pdf transmission.

Section 9.7. Assignment; No Third Party Beneficiaries.

(a) This Agreement and all of the provisions hereto shall be binding upon and inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations set forth herein shall be assigned by any party hereto without the prior written consent of the other parties hereto and any purported assignment without such consent shall be void.

(b) Nothing in this Agreement shall be construed as giving any Person, other than the parties hereto and their heirs, successors, legal representatives and permitted assigns, any right, remedy or claim under or in respect of this Agreement or any provision hereof. Notwithstanding the foregoing, from and after the Effective Time, Section 6.9 (with respect to which the Indemnified Parties shall be third party beneficiaries) is for the benefit of the Persons named therein and such Persons may specifically enforce such provisions.

Section 9.8. Severability. If any provision of this Agreement shall be held to be illegal, invalid or unenforceable under any applicable Law, then such contravention or invalidity shall not invalidate the entire Agreement. Such provision shall be deemed to be modified to the extent necessary to render it legal, valid and enforceable, and if no such modification shall render it legal, valid and enforceable, then this Agreement shall be construed as if not containing the provision held to be invalid, and the rights and obligations of the parties shall be construed and enforced accordingly.

Section 9.9. Entire Agreement. This Agreement (including the Company Disclosure Letter, the Exhibits hereto and the documents and instruments referred to herein that are to be delivered at Closing) and the Confidentiality Agreement contain all of the terms of the understandings of the parties hereto with respect to the subject matter hereof and supersedes any prior understandings, agreements or representations by or among the parties hereto, or any of them, whether written or oral, with respect to the subject matter hereof, and the parties hereto specifically disclaim reliance on any such prior understandings, agreements or representations to the extent not embodied in this Agreement. The representations and warranties set forth in Articles 3 and 4 and (except as otherwise expressly set forth herein) the covenants set forth in this Agreement have been made solely for the benefit of the parties to this Agreement and (a) may be intended not as statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate; (b) have been qualified by reference to the Company Disclosure Letter, which contains certain disclosures that are not reflected in the text of this Agreement; and (c) may apply standards of materiality in a way that is different from what may be viewed as material by shareholders of, or other investors in, the Company.

Section 9.10. Enforcement.

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties agree that irreparable damage would occur 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 and this right shall include the right of the parties to cause the Transactions to be consummated on the terms set forth in this Agreement, in each case without posting a bond or undertaking, this being in addition to any other remedy to which they are entitled at Law or in equity or pursuant to this Agreement. Each of the parties hereto hereby waives any defenses in any action for specific performance, including the defense that a remedy at Law would be adequate.

(b) Notwithstanding the parties’ rights to specific performance or injunctive relief or both pursuant to Section 9.10(a), each party may pursue any other remedy available to it at Law or in equity, including monetary damages; provided, that it is understood and agreed that claims for monetary damages following termination of this Agreement shall be limited to those arising from or relating to any willful breach of this Agreement prior to such termination. If a court has granted an award of damages in connection with any willful breach by Parent and/or Merger Sub of the terms or conditions set forth in this Agreement, the Company may, on behalf of its stockholders, enforce such award and accept damages for such breach, and Parent agrees that such damages shall not be limited to reimbursement of expenses or out-of-pocket costs, and may include the benefit of the bargain lost by the Company’s stockholders (taking into consideration relevant matters, including other combination opportunities and the time value of money). Notwithstanding anything in this Agreement to the contrary, prior to the termination of this Agreement in accordance with its terms, no party hereto shall be permitted to make commence any action, suit or proceeding seeking monetary damages against any other party

hereto in connection with or arising out of this Agreement or the Transactions, provided that the foregoing shall be without prejudice to the right of any party to seek such monetary damages following such termination in accordance with, and subject to the limitations set forth in, this Agreement.

Section 9.11. Disclosure Letter. The inclusion of any information in the Company Disclosure Letter shall not be deemed to be an admission or acknowledgment, in and of itself, that such information is required by the terms hereof to be disclosed, is material, has had or is reasonably expected to have a Company Material Adverse Effect or is outside the Ordinary Course of Business.

This Note evidences unsecured, non-negotiable and non-transferable indebtedness of the Maker.

If an Event of Default (as defined below) under this Note shall occur and be continuing, then the Payee shall have the right to declare the entire principal balance and all accrued interest under this note due and payable.

Exhibit C

Form of Amended Certificate of Incorporation of the Surviving Corporation

1. The name of the corporation is Inspire Pharmaceuticals, Inc. (the “Corporation”).

2. The address of its registered office in the State of Delaware is 0000 Xxxxxx Xxxxxx, in the City of Wilmington, County of Xxx Xxxxxx, Xxxxxxxx, 00000. The name of its registered agent at such address is The Corporation Trust Company.

3. The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”).

4. The total number of shares of stock which the Corporation shall have authority to issue is 1,000, all of which shall be shares of Common Stock with the par value of $0.01 per share.

5. The Board of Directors shall have the power to adopt, amend or repeal the bylaws of the Corporation.

6. Unless and except to the extent that the By-laws of the Corporation (the “By-laws”) shall so require, the election of directors of the Corporation need not be by written ballot.

7. The Corporation expressly elects not to be governed by Section 203 of the DGCL.

8. To the fullest extent permitted under the DGCL, as amended from time to time, no director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. Any amendment or repeal of the foregoing provision shall not adversely affect any right or protection of a director of the Corporation hereunder in respect of any act or omission occurring prior to the time of such amendment or repeal.

9. (a) Actions, Suits and Proceedings Other than by or in the Right of the Corporation. The Corporation shall indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation), by reason of the fact that he is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) (all such persons being referred to hereafter as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, if he

C-1

acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in, or not opposed to, the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. Notwithstanding anything to the contrary in this Section 9, except as set forth in Section 9(f) below, the Corporation shall not indemnify an Indemnitee seeking indemnification in connection with a proceeding (or part thereof) initiated by the Indemnitee unless the initiation thereof was approved by the Board of Directors of the Corporation.

(b) Actions or Suits by or in the Right of the Corporation. The Corporation shall indemnify any Indemnitee who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses (including attorneys’ fees) which the Court of Chancery of Delaware or such other court shall deem proper.

(c) Indemnification for Expenses of Successful Party. Notwithstanding the other provisions of this Section 9, to the extent that an Indemnitee has been successful, on the merits or otherwise, in defense of any action, suit or proceeding referred to in Sections 9(a) and 9(b), or in defense of any claim, issue or matter therein, or on appeal from any such action, suit or proceeding, he shall be indemnified against all expenses (including attorneys’ fees) actually and reasonably incurred by him or on his behalf in connection therewith. Without limiting the foregoing, if any action, suit or proceeding is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the Indemnitee did not act in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and (v) with respect to any criminal proceeding, an adjudication that the Indemnitee had reasonable cause to believe his conduct was unlawful, the Indemnitee shall be considered for the purposes hereof to have been wholly successful with respect thereto.

C-2

(d) Notification and Defense of Claim. As a condition precedent to his right to be indemnified, the Indemnitee must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving him for which indemnity will or could be sought. With respect to any action, suit, proceeding or investigation of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to the Indemnitee. After notice from the Corporation to the Indemnitee of its election so to assume such defense, the Corporation shall not be liable to the Indemnitee for any legal or other expenses subsequently incurred by the Indemnitee in connection with such claim, other than as provided below in this Section 9(d). The Indemnitee shall have the right to employ his own counsel in connection with such claim, but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of the Indemnitee unless (i) the employment of counsel by the Indemnitee has been authorized by the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and the Indemnitee in the conduct of the defense of such action or (iii) the Corporation shall not in fact have employed counsel to assume the defense of such action, in each of which cases the fees and expenses of counsel for the Indemnitee shall be at the expense of the Corporation, except as otherwise expressly provided by this Section 9. The Corporation shall not be entitled, without the consent of the Indemnitee, to assume the defense of any claim brought by or in the right of the Corporation or as to which counsel for the Indemnitee shall have reasonably made the conclusion provided for in clause (ii) above.

(e) Advance of Expenses. Subject to the provisions of Section 9(f) below, in the event that the Corporation does not assume the defense pursuant to Section 9(d) of any action, suit, proceeding or investigation of which the Corporation receives notice under this Section 9, any expenses (including attorneys’ fees) incurred by an Indemnitee in defending a civil or criminal action, suit, proceeding or investigation or any appeal therefrom shall be paid by the Corporation in advance of the final disposition of such matter, provided, however, that the payment of such expenses incurred by an Indemnitee in advance of the final disposition of such matter shall be made only upon receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that the Indemnitee is not entitled to be indemnified by the Corporation as authorized in this Section 9. Such undertaking may be accepted without reference to the financial ability of such person to make such repayment.

(f) Procedure for Indemnification. In order to obtain indemnification or advancement of expenses pursuant to Sections 9(a), 9(b), 9(c) or 9(e), the Indemnitee shall submit to the Corporation a written request, including in such request such documentation and information as is reasonably available to the Indemnitee and is reasonably necessary to determine whether and to what extent the Indemnitee is entitled to indemnification or advancement of expenses. Any such indemnification or advancement of expenses shall be made promptly, and in any event within 60 days after receipt by the Corporation of the written request of the Indemnitee, unless with respect to requests under Sections 9(a), 9(b) or 9(e) the Corporation determines, by clear and convincing evidence, within such 60-day period that the Indemnitee did not meet the applicable standard of conduct set forth in Sections 9(a) or 9(b), as the case may be. Such determination shall be made in each instance by (a) a majority vote of a

C-3

quorum of the directors of the Corporation consisting of persons who are not at that time parties to the action, suit or proceeding in question (“disinterested directors”), (b) if no such quorum is obtainable, a majority vote of a committee of two or more disinterested directors, (c) a majority vote of a quorum of the outstanding shares of stock of all classes entitled to vote for directors, voting as a single class, which quorum shall consist of stockholders who are not at that time parties to the action, suit or proceeding in question, (d) independent legal counsel (who may be regular legal counsel to the Corporation), or (e) a court of competent jurisdiction.

(g) Remedies. The right to indemnification or advances as granted by this Section 9 shall be enforceable by the Indemnitee in any court of competent jurisdiction if the Corporation denies such request, in whole or in part, or if no disposition thereof is made within the 60-day period referred to above in Section 9(f). Unless otherwise provided by law, the burden of proving that the Indemnitee is not entitled to indemnification or advancement of expenses under this Section 9 shall be on the Corporation. Neither the failure of the Corporation to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances because the Indemnitee has met the applicable standard of conduct, nor an actual determination by the Corporation pursuant to Section 9(f) that the Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the Indemnitee has not met the applicable standard of conduct. The Indemnitee’s expenses (including attorneys’ fees) incurred in connection with successfully establishing his right to indemnification, in whole or in part, in any such proceeding shall also be indemnified by the Corporation.

(h) Subsequent Amendment. No amendment, termination or repeal of this Section 9 or of the relevant provisions of the DGCL or any other applicable laws shall affect or diminish in any way the rights of any Indemnitee to indemnification under the provisions hereof with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the final adoption of such amendment, termination or repeal.

(i) Other Rights. The indemnification and advancement of expenses provided by this Section 9 shall not be deemed exclusive of any other rights to which an Indemnitee seeking indemnification or advancement of expenses may be entitled under any law (common or statutory), agreement or vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in any other capacity while holding office for the Corporation, and shall continue as to an Indemnitee who has ceased to be a director or officer, and shall inure to the benefit of the estate, heirs, executors and administrators of the Indemnitee. Nothing contained in this Section 9 shall be deemed to prohibit, and the Corporation is specifically authorized to enter into, agreements with officers and directors providing indemnification rights and procedures different from those set forth in this Section 9. In addition, the Corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification rights to other employees or agents of the Corporation or other persons serving the Corporation and such rights may be equivalent to, or greater or less than, those set forth in this Section 9.

(j) Partial Indemnification. If an Indemnitee is entitled under any provision of this Section 9 to indemnification by the Corporation for some or a portion of the expenses

C-4

(including attorneys’ fees), judgments, fines or amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with any action, suit, proceeding or investigation and any appeal therefrom but not, however, for the total amount thereof, the Corporation shall nevertheless indemnify the Indemnitee for the portion of such expenses (including attorneys’ fees), judgments, fines or amounts paid in settlement to which the Indemnitee is entitled.

(k) Insurance. The Corporation may purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) against any expense, liability or loss incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

(l) Merger or Consolidation. If the Corporation is merged into or consolidated with another corporation and the Corporation is not the surviving corporation, the surviving corporation shall assume the obligations of the Corporation under this Section 9 with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the date of such merger or consolidation.

(m) Savings Clause. If this Section 9 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each Indemnitee as to any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with any action, suit, proceeding or investigation, whether civil, criminal or administrative, including an action by or in the right of the Corporation, to the fullest extent permitted by any applicable portion of this Section 9 that shall not have been invalidated and to the fullest extent permitted by applicable law.

(n) Definitions. Terms used herein and defined in Section 145(h) and Section 145(i) of the DGCL shall have the respective meanings assigned to such terms in such Section 145(h) and Section 145(i).

(o) Subsequent Legislation. If the DGCL is amended after adoption of this Section 9 to expand further the indemnification permitted to Indemnitees, then the Corporation shall indemnify such persons to the fullest extent permitted by the DGCL, as so amended.

10. The Corporation reserves the right at any time, and from time to time, to amend or repeal any provision contained in this Certificate of Incorporation, and add other provisions authorized by the laws of the State of Delaware at the time in force, in the manner now or hereafter prescribed by applicable law; and all rights, preferences and privileges of whatsoever nature conferred upon stockholders, directors or any other persons whomsoever by and pursuant to this Certificate of Incorporation (as amended) are granted subject to the rights reserved in this Section.
