AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of May 16, 2010 (this “Agreement”), by and among Astellas Pharma Inc., a corporation formed under the laws of Japan (“Parent”), Astellas US Holding, Inc., a Delaware corporation and a wholly-owned subsidiary of the Parent, Ruby Acquisition, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Holding and an indirect wholly-owned subsidiary of Parent (“Merger Sub”), and OSI Pharmaceuticals, Inc. a Delaware corporation (the “Company”).

WITNESSETH:

WHEREAS, Merger Sub has previously commenced a cash tender offer (the “Pending Offer”) to purchase all of the issued and outstanding shares of common stock, par value $0.01 per share, of the Company (each, a “Share” and, collectively, “Shares”), together with the Rights attached thereto or associated therewith, for $52.00 per Share, net to the seller in cash, subject to any withholding of Taxes required by applicable Law and subject to certain terms and conditions; and

WHEREAS, Parent, Holding, Merger Sub and the Company have agreed to the acquisition of the Company on the terms and subject to the conditions set forth herein and, accordingly, Merger Sub has agreed to amend the Pending Offer to provide for the purchase of all of the issued and outstanding Shares (as the Pending Offer is so amended and as it may be amended from time to time as permitted by this Agreement, the “Offer”), for $57.50 per Share, net to the seller in cash (such price, or any other price per Share as may be paid in the Offer pursuant to the terms of this Agreement, is referred to herein as the “Offer Price”), without interest, subject to any withholding of Taxes required by applicable Law and subject to the conditions set forth herein; and

WHEREAS, in furtherance of the transaction, it is proposed that, following the acceptance for payment of Shares pursuant to the Offer, upon the terms and subject to the conditions set forth in this Agreement, Merger Sub will be merged with and into the Company, with the Company continuing as the Surviving Corporation (the “Merger”), in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), whereby each issued and outstanding Share (other than Shares to be canceled in accordance with Section 3.1(b) of this Agreement and the Appraisal Shares) will be converted into the right to receive the Offer Price, payable net to the holder in cash, without interest, subject to any withholding of Taxes required by applicable Law; and

WHEREAS, the board of directors of the Company (the “Company Board”) has, upon the terms and subject to the conditions set forth herein, (i) determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, are advisable and in the best interests of the Company and its stockholders, (ii) approved and declare advisable this Agreement and the transactions contemplated hereby, including, the Offer and the Merger and, (iii) recommended that the stockholders of the Company accept the Offer and tender their Shares pursuant to the Offer and, to the extent required to consummate the Merger, adopt this Agreement and approve the Merger (the “Company Board Recommendation”); and

WHEREAS, the respective boards of directors of Parent, Holding and Merger Sub have, upon the terms and subject to the conditions set forth herein, approved and declared advisable this Agreement and the transactions contemplated hereby, including the Offer and the Merger; and

WHEREAS, Holding, as the sole stockholder of Merger Sub, has approved and adopted this Agreement and approved the transactions contemplated hereby, including the Offer and the Merger, upon the terms and subject to the conditions set forth in this Agreement; and

WHEREAS, Parent, Holding, Merger Sub and the Company wish to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and to prescribe certain conditions to the consummation of the Offer and the Merger as set forth herein; and

WHEREAS, terms used but not defined herein shall have the meanings set forth in Section 9.3, unless otherwise noted.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements of the parties set forth in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

THE OFFER

1.1The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Article VIII hereof, Parent shall cause Merger Sub to, and Merger Sub shall, amend the Pending Offer to reflect the execution of this Agreement and the terms hereof as promptly as practicable after the date of this Agreement (but in no event later than the fifth (5th) Business Day following the date of this Agreement). The date on which Merger Sub amends the Pending Offer is referred to in this Agreement as the “Offer Amendment Date.”

(b) The obligation of Merger Sub to accept for payment (and the obligation of Parent to cause Merger Sub to accept for payment) Shares and associated Rights validly tendered (and not withdrawn) pursuant to the Offer shall only be subject to (i) the condition that there shall be validly tendered in accordance with the terms of the Offer (and not withdrawn) prior to the Expiration Date a number of Shares that, together with any Shares owned by Parent, Holding or Merger Sub immediately prior to the acceptance for payment of Shares and associated Rights pursuant to the Offer or with respect to which Parent, Holding or Merger Sub otherwise has, directly or indirectly, sole voting power, represents more than 50% of the Adjusted Outstanding Share Number (as defined below) at the Expiration Date (the “Minimum Condition”) and (ii) the satisfaction or waiver by Parent of the other conditions set forth inAnnex I. The Minimum Condition and the other conditions set forth inAnnex I are referred to collectively as the “Offer Conditions.” For purposes of this Agreement, the “Adjusted

Outstanding Share Number” shall be the sum of (x) the aggregate number of Shares issued and outstanding immediately prior to the Acceptance Time (as defined herein), plus (y) the sum of (A) the aggregate number of Shares issuable upon the exercise of all Company Options and conversion of all Company RSUs, Company DSUs and other rights to acquire Shares that are outstanding immediately prior to the acceptance of Shares for payment pursuant to the Offer and that are vested and exercisable or may become vested and exercisable prior to the Effective Time, plus (B) the aggregate number of Shares issuable upon conversion of all Convertible Notes that are outstanding immediately prior to the Acceptance Time and that are convertible into such Shares or may become convertible into such Shares prior to the Effective Time.

(c) Parent and Merger Sub expressly reserve the right to (i) increase the Offer Price and (ii) waive or make any other changes to the terms and conditions of the Offer;provided,however, that without the prior written consent of the Company: (A) the Minimum Condition may not be amended or waived; and (B) no change may be made to the Offer that (1) changes the form of consideration to be delivered by Merger Sub pursuant to the Offer, (2) decreases the Offer Price, (3) decreases the number of Shares to be purchased by Merger Sub in the Offer, (4) imposes conditions to the Offer in addition to the Offer Conditions, (5) amends the Offer Conditions so as to broaden the scope of the Offer Conditions, (6) except as provided in Section 1.1(d), extends the Expiration Date beyond the Initial Expiration Date or (7) otherwise amends any other term or condition of the Offer in a manner adverse to the holders of Shares. Subject to the terms and conditions of the Offer and this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, (x) accept for payment all Shares and associated Rights validly tendered (and not withdrawn) pursuant to the Offer promptly, and in any event in compliance with Rule 14e-1(c) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and, if applicable, Rule 14d-11 of the Exchange Act and (y) promptly pay the Offer Price in exchange for each Share and associated Rights accepted for payment pursuant to the Offer.

(d) Subject to the terms and conditions of this Agreement, the Offer shall initially be scheduled to expire no later than ten (10) Business Days following the Offer Amendment Date (calculated as set forth in Rule 14d-1(g)(3) under the Exchange Act) (the “Initial Expiration Date”), or if the Initial Expiration Date has been extended in accordance with this Agreement, the date on which the Offer has been so extended (the Initial Expiration Date, or such later date to which the Initial Expiration Date has been extended in accordance with this Agreement, the “Expiration Date”). Notwithstanding anything to the contrary contained in this Agreement, but subject to the parties’ respective termination rights under Section 8.1, (i) if, at the time of any then scheduled Expiration Date, any Offer Condition is not satisfied and has not been waived, then, subject to the parties’ respective termination rights under Section 8.1, Merger Sub shall extend the Offer on one or more occasions, for additional successive periods of up to ten (10) Business Days per extension (with the length of such periods to be determined by Parent upon consultation with the Company), until all Offer Conditions are satisfied or validly waived in order to permit the Acceptance Time to occur;provided, however, that in no event shall Merger Sub be required to extend the Offer beyond the Outside Date or if, in the reasonable discretion of Parent and Merger Sub, any Offer Condition is not reasonably capable of being satisfied on or before the Outside Date, and (ii) Merger Sub shall extend the Offer from time to time for any period required by any rule, regulation, interpretation or position of the SEC or the

staff of the SEC or the Nasdaq Stock Market applicable to the Offer;provided, however, that in no event shall Merger Sub be required to extend the Offer beyond the Outside Date. Merger Sub may, in its sole discretion (and without the consent of the Company or any other person), elect to provide for a subsequent offering period (and up to two five Business Day extensions thereof) (a “Subsequent Offering Period”) in accordance with Rule 14d-11 under the Exchange Act if, as of the commencement of such period, the number of Shares that have been validly tendered (excluding Shares tendered pursuant to the guaranteed delivery procedures that have not yet been delivered in settlement or satisfaction of the guarantee), and not properly withdrawn pursuant to the Offer would be insufficient to permit the Merger to be effected without a meeting of stockholders of the Company in accordance with Section 253(a) of the DGCL. Subject to the terms and conditions of this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, promptly accept for payment, and pay for, all Shares and associated Rights that are validly tendered during any such Subsequent Offering Period (or any extension thereof).

(e) Merger Sub shall not terminate or withdraw the Offer prior to the Outside Date without the prior written consent of the Company, unless this Agreement is earlier terminated pursuant to Article VIII.

(f) On the Offer Amendment Date, Parent or Merger Sub shall: (i) cause to be filed with the SEC an amendment to Parent’s Tender Offer Statement on Schedule TO, as amended and originally filed on March 2, 2010 with respect to the Pending Offer, which amendment shall reflect the execution of this Agreement and the terms hereof and shall include as exhibits (A) an amended offer to purchase Shares pursuant to the Offer (the “Offer to Purchase”) and (B) forms of the related letter of transmittal and notice of guaranteed delivery; and (ii) subject to the Company’s compliance withSection 1.2, cause the Offer to Purchase and related documents to be disseminated to holders of Shares. Parent and Merger Sub shall use commercially reasonable efforts to cause such Tender Offer Statement on Schedule TO and all exhibits, amendments and supplements thereto (collectively, the “Offer Documents”) and the filing and dissemination thereof to comply in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder and with all other applicable Laws. The Company and its legal counsel shall be given reasonable opportunity to review and comment on the Offer Documents (including all amendments and supplements thereto) prior to the filing thereof with the SEC, and Parent and Merger Sub shall give due consideration to the additions, deletions or changes thereto suggested by the Company and its legal counsel. Parent and Merger Sub shall promptly provide the Company and its legal counsel with a copy of any written comments and a description of any oral comments received by Parent, Merger Sub or their legal counsel from the SEC or its staff with respect to the Offer Documents. The Company and its legal counsel shall be given reasonable opportunity to review and comment on Parent and Merger Sub’s proposed responses to the comments prior to the filing thereof with the SEC, and Parent and Merger Sub shall give due consideration to all additions, deletions or changes thereto suggested by the Company and its legal counsel. Parent and Merger Sub shall use commercially reasonable efforts to respond promptly to any such comments. If at any time prior to the Effective Time any information relating to the Offer, the Merger, the Company, Parent, Merger Sub or any of their respective Affiliates, directors, or officers should be discovered by the Company or Parent which should be set forth in an amendment or supplement to any of the Offer Documents, so that the Offer Documents 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 are made, not misleading, the party which discovers such information shall promptly notify the other parties, and an appropriate amendment or supplement describing such information shall be filed with the SEC and disseminated to the stockholders of the Company, as and to the extent required by the applicable requirements of the Exchange Act and the rules and regulations thereunder or by other applicable Law. The Company shall promptly furnish to Parent and Merger Sub, upon the written request of either such party, all information concerning the Company that may be required by applicable Law or reasonably requested in connection with any action contemplated by this Section 1.1(f).

(g) If, between the date of this Agreement and the Acceptance Time, the outstanding Shares are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, or if a record date with respect to any such event shall occur during such period, then the Offer Price shall be appropriately adjusted.

1.2Company Actions.

(a) Contemporaneously with the filing of the amendment to Schedule TO or as promptly as practicable thereafter (but in no event later than the fifth (5^th) Business Day after the date of this Agreement), the Company shall file with the SEC and (following or contemporaneously with the dissemination of the Offer to Purchase and related documents) disseminate to holders of Shares an amendment to its Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, the “Schedule 14D-9”) that, subject to Section 5.2, shall reflect the Company Board Recommendation. The Company shall use commercially reasonable efforts to cause the Schedule 14D-9 and the filing and dissemination thereof to comply in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder and with all other applicable Law. Parent and its legal counsel shall be given reasonable opportunity to review and comment on the Schedule 14D-9 (including any amendment or supplement thereto) prior to the filing thereof with the SEC, and the Company shall give due consideration to all additions, deletions or changes thereto suggested by Parent and its legal counsel. The Company shall promptly provide Parent and its legal counsel with a copy of any written comments and a description of any oral comments received by the Company or its legal counsel from the SEC or its staff with respect to the Schedule 14D-9. Parent and its legal counsel shall be given reasonable opportunity to review and comment on the Company’s proposed responses to the comments prior to the filing thereof with the SEC, and the Company shall give due consideration to all additions, deletions or changes thereto suggested by the Parent and its legal counsel. The Company shall use commercially reasonable efforts to respond promptly to any such comments. If at any time prior to the Effective Time, any information relating to the Offer, the Merger, the Company, Parent, Merger Sub or any of their respective Affiliates, directors, or officers should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Schedule 14D-9, so that the Schedule 14D-9 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 are made, not misleading, the party which discovers such information shall promptly notify the other parties, and an appropriate amendment or supplement describing such information shall be filed with the SEC and disseminated to the stockholders of the Company, as and to the extent required by the applicable requirements of the Exchange Act and the rules and regulations thereunder or by other applicable Law. Parent, Holding and Merger Sub shall promptly furnish to the Company upon the Company’s written request all information concerning Parent, Holding, Merger Sub and the Offer that may be required or reasonably requested in connection with any action contemplated by this Section 1.2(a).

(b) The Company shall as promptly as practicable after the date of this Agreement provide to Parent, or cause to be provided to Parent, (i) a list of the Company’s stockholders as well as mailing labels and any available listing or computer file containing the names and addresses of all record holders of Shares and lists of securities positions of Shares held in stock depositories, in each case accurate and complete as of the most recent practicable date, and (ii) such additional information (including updated lists of stockholders, mailing labels and lists of securities positions) and such other assistance as Parent may reasonably request in connection with the Offer. Except as may be required by applicable Law or legal process, and except as may be necessary to disseminate the Offer Documents or as otherwise permitted by this Agreement, Parent and Merger Sub shall hold in confidence, in accordance with the terms of the Confidentiality Agreement and this Agreement, any information contained in any such labels, listings and files provided by the Company to Parent until the Effective Time.

1.3Directors.

(a) After Merger Sub initially accepts for payment Shares validly tendered and not withdrawn pursuant to the Offer (the “Acceptance Time”) and at all times thereafter, Parent shall be entitled to elect or designate, to serve on the Company Board, the number of directors, rounded up to the next whole number, determined by multiplying: (i) the total number of directors on the Company Board (giving effect to any increase in the size of the Company Board effected pursuant to this Section 1.3(a)); by (ii) a fraction having a numerator equal to the aggregate number of Shares then beneficially owned by Parent, Holding or Merger Sub (including all Shares accepted for payment pursuant to the Offer), and having a denominator equal to the total number of Shares then issued and outstanding. Promptly following Parent’s request after the Acceptance Time, the Company shall cause Parent’s designees to be elected or appointed to the Company Board, including seeking and accepting resignations of incumbent directors and, if such resignations are not obtained, increasing the size of the Company Board. From and after the Acceptance Time, to the extent requested by Parent, the Company shall also, to the maximum extent permitted by applicable Law (including the rules of the Nasdaq Global Select Market), cause individuals designated by Parent to constitute the number of members, rounded up to the next whole number, on each committee of the Company Board that represents at least the same percentage as individuals designated by Parent represent on the Company Board. Notwithstanding the provisions of this Section 1.3, at all times prior to the Effective Time (as defined in Section 2.3), the Company, Parent and Merger Sub shall cause the Company Board to include, at all times prior to the Effective Time, at least three of the members of the Company Board, selected by the members of the Company Board, who were directors of the

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

(b) In connection with the performance of its obligations to cause Parent’s designees to be elected or appointed to the Company Board, each of the Company and Parent shall use its commercially reasonable efforts to promptly take all actions, and the Company shall cause to be included in the Schedule 14D-9 such information with respect to the Company and its officers and directors (including Parent’s designees), as Section 14(f) of the Exchange Act and Rule 14f-1 thereunder require (subject to the Company’s receipt of the information with respect to Parent and its nominees, officers, directors and affiliates required by Section 14(f) of the Exchange Act and Rule 14f-1 thereunder). Parent shall supply to the Company in writing and be solely responsible for any information with respect to itself and its nominees, officers, directors and Affiliates required by Section 14(f) and Rule 14f-1 under the Exchange Act.

(c) Following the election or appointment of Parent’s designees to the Company Board pursuant to Section 1.3(a) (the date of such election or appointment, the “Control Date”) and until the Effective Time (the “Interim Period”), each of the following actions may be effected only if there are on the Company Board one or more Continuing Directors and such action is approved by a majority of such Continuing Directors (or by such Continuing Director should there be only one): (i) action by the Company with respect to any amendment, supplement, modification, waiver or of any term or condition of this Agreement; (ii) termination of this Agreement by the Company; (iii) extension by the Company of the time for the performance of any of the obligations or other acts of Parent or Merger Sub; (iv) any waiver or assertion of any of the Company’s rights under this Agreement; (v) amendment to the Restated Certificate of Incorporation or Second Amended and Restated Bylaws of the Company; (vi) authorization of any agreement between the Company and any of its Affiliates, on the one hand, and Parent, Merger Sub or any of their Affiliates on the other hand, or (vii) any other consent or action by the Company with respect to the Offer, the Merger or any of the other Transactions. To the extent permitted under applicable Law, during the Interim Period, in addition to any requirements under the Company’s Restated Certificate of Incorporation and Second Amended and Restated Bylaws, any quorum of the Company Board for the purposes of any meeting thereof or transacting of business thereby with respect to the approval of any of the foregoing actions shall be deemed to require the attendance of at least one Continuing Director. The Continuing Directors shall have, and Parent shall cause the Continuing Directors to have, the authority to retain such counsel (which may include current counsel to the Company or the

Company Board) and other advisors with respect to the foregoing actions or otherwise relating to their service on the Company Board at the expense of the Company as reasonably determined by the Continuing Directors, and the authority to institute any action on behalf of the Company to enforce the performance of this Agreement. The Company shall indemnify and advance expenses to, and Parent shall cause the Company to indemnify and advance expenses to, the Continuing Directors in connection with their service as directors of the Company prior to the Effective Time to the fullest extent permitted by applicable Law and in accordance with the provisions of Section 6.6 hereof.

1.4Top-Up Option.

(a)(a) The Company grants to Parent and Merger Sub an irrevocable option (the “Top-Up Option”), exercisable only upon the terms and subject to the conditions set forth in this Agreement, to purchase from the Company an aggregate number of newly-issued Shares equal to the lesser of (i) the number of Shares that, when added to the number of Shares owned by Parent or Merger Sub or any other Subsidiaries of Parent at the time of exercise of the Top-Up Option, constitutes one share more than 90% of the sum of the Adjusted Outstanding Share Number plus such additional Shares that would be outstanding immediately after the issuance of all Shares subject to the Top-Up Option and (ii) the aggregate number of shares of Company Common Stock that the Company is authorized to issue under its Restated Certificate of Incorporation but that are not issued and outstanding (and are not subscribed for or otherwise committed to be issued under the Equity Compensation Plans, upon conversion of the Convertible Notes or otherwise) at the time of exercise of the Top-Up Option.

(b) The Top-Up Option may be exercised by Parent or Merger Sub, in whole but not in part, at any time at or after the Acceptance Time, and no exercise of the Top-Up Option shall be effective prior to the Acceptance Time;provided that the Top-Up Option shall terminate upon the earlier of (i) the fifth (5^th) Business Day after the later of (x) the Acceptance Time and (y) the expiration of any “subsequent offering period”; and (ii) the termination of this Agreement in accordance with its terms. The aggregate purchase price payable for the Shares being purchased by Parent or Merger Sub pursuant to the Top-Up Option shall be determined by multiplying the number of such Shares by the Offer Price and shall be payable, at Parent’s election, in cash or by executing and delivering to the Company a promissory note having a principal amount equal to the aggregate purchase price to be paid pursuant to the Top-Up Option (the “Promissory Note”), or by any combination thereof. Any such Promissory Note shall be full recourse against Parent and Merger Sub and (i) shall bear interest at the rate of 5% per annum, (ii) shall mature on the six month anniversary of the date of execution and delivery of such Promissory Note and (iii) may be prepaid, in whole or in part, without premium or penalty.

ARTICLE III

EFFECT OF THE MERGER; EXCHANGE OF CERTIFICATES

3.1Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holders of any shares of capital stock of the Company or any shares of capital stock of Parent, Holding or Merger Sub:

(a)Conversion of Shares. Each Share issued and outstanding immediately prior to the Effective Time, other than (i) Shares to be canceled in accordance with Section 3.1(b) of this Agreement and (ii) the Appraisal Shares (as defined in Section 3.1(d) of this Agreement) (the “Excluded Shares”) shall be converted into the right to receive (upon compliance with the exchange procedures set forth in Section 3.2), in cash, an amount equal to the Offer Price, without interest (the “Merger Consideration”). At the Effective Time, all such Shares shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and the holder of any such Share shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration. The right of any holder of a Share to receive the Merger Consideration shall be subject to the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 3.2(i) of this Agreement. The Merger Consideration shall be paid in the manner set forth in Section 3.2.

(b)Cancellation of Treasury Stock and Parent-Owned Stock. Each Share that is owned by the Company, Parent, Holding, Merger Sub, or any direct or indirect Subsidiary of the Company or Parent immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c)Common Stock of Merger Sub. All issued and outstanding shares of common stock, par value $0.001 per share, of Merger Sub shall be converted into and become 100,000,000 validly issued, fully paid and non-assessable shares of common stock, par value $0.01 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(d)Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, Shares issued and outstanding immediately prior to the Effective Time that are held by any holder who is entitled to demand and properly demands appraisal (the “Appraisal Shares”) of such Appraisal Shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (“Section 262”) shall not be converted into the right to receive the Merger Consideration as provided in Section 3.1(a) of this Agreement, but instead such holder shall be entitled to payment of the fair value of such Appraisal Shares in accordance with the provisions of Section 262. At the Effective Time, all Appraisal Shares shall no longer be outstanding, shall automatically be canceled and retired and shall cease to exist, and each holder of Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such Appraisal Shares in accordance with the provisions of Section 262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262 shall cease and such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 3.1(a) of this Agreement, without interest. The Company shall serve prompt notice to Parent of any demands for appraisal of any Shares, and Parent shall have the right to participate in and 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 (which consent shall not be unreasonably conditioned, withheld or delayed), voluntarily make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

3.2Exchange of Shares.

(a)Paying Agent. The parties hereto agree to the appointment of Computershare (or such replacement as reasonably selected by Parent) to act as paying agent (the “Paying Agent”) for the payment of the Merger Consideration. At the Effective Time, Parent shall deposit, or cause the Surviving Corporation to deposit, with the Paying Agent, for the benefit of the holders of Certificates (as defined below), cash in an amount sufficient to pay the aggregate Merger Consideration required to be paid pursuant to Section 3.1(a) of this Agreement (such cash being hereinafter referred to as the “Exchange Fund”).

(b)Exchange Procedures. As soon as reasonably practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of a Share (other than holders of Excluded Shares) (i) a form of letter of transmittal (which shall specify when delivery of Shares shall be effected, and, with respect to certificates representing Shares immediately prior to the Effective Time (“Certificates”), that the risk of loss and title to Certificates shall pass only upon proper delivery of the Certificates to the Paying Agent and which letter of transmittal shall be in customary form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of Certificates in exchange for the Merger Consideration. Each holder of record of a Share (other than holders of Excluded Shares) shall, upon the submission of a letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, be entitled to receive in exchange therefor the amount of cash which the number of Shares held by such holder shall have been converted into the right to receive pursuant to Section 3.1(a) of this Agreement, and any Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares which is not registered in the transfer records of the Company, payment of the Merger Consideration 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 of the Merger Consideration to a person other than the registered holder of such Certificate or establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 3.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration which the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article III. No interest shall be paid or will accrue on any cash payable to holders of Shares pursuant to the provisions of this Article III.

(c)No Further Ownership Rights in Shares. All cash paid upon the surrender of Shares in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to such Shares. At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate is presented to the Surviving Corporation for transfer, it shall be canceled against delivery of cash to the holder thereof as provided in this Article III.

(d)Termination of the Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of the Certificates for one year after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Certificates who have not theretofore complied with this Article III shall thereafter look only to Parent for, and Parent shall remain liable for, payment of their claim for the Merger Consideration.

(e)No Liability. None of Parent, Holding, Merger Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any cash from the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to the date on which the applicable Merger Consideration would otherwise escheat to or become the property of any Governmental Entity, any such Merger Consideration shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any person previously entitled thereto.

(f)Investment of Exchange Fund. The Paying Agent shall invest the cash comprising the Exchange Fund as directed by Parent on a daily basis provided, however, that any investment of such cash shall in all events be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government, in commercial paper rated A-1 or P-1 or better by Moody’s Investors 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 that are then publicly available), and that no such investment or loss thereon shall affect the amounts payable to holders of Shares pursuant to this Article III. Any interest and other income resulting from such investments shall be paid to Holding.

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

(h)Adjustments. If at any time during the period between the date of this Agreement and the Effective Time, a change in the outstanding shares of capital stock of the Company shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, the Merger Consideration shall be adjusted appropriately.

(i)Withholding Rights. Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares, Company Options, Company RSUs or Company DSUs, as applicable, such amounts as Parent, the Surviving Corporation or the Paying Agent, as applicable, is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares, Company Options, Company RSUs or Company DSUs, as applicable, in respect of which such deduction and withholding was made by such party.

3.3Associated Rights. References in Article III of this Agreement to Company Common Stock shall include, unless the context requires otherwise, the associated rights (the “Rights”) issued pursuant to the Rights Agreement, dated September 27, 2000 (the “Rights Agreement”), between the Company and The Bank of New York (the “Rights Agent”).

requirements applicable to such employees and their eligible dependents and beneficiaries, to the extent such limitations were waived, satisfied or did not apply to the applicable employee or eligible dependent or beneficiary under the corresponding welfare Company Benefit Plan in which he or she participated immediately prior to the Changeover Time, and (ii) provide each Company Employee and his or her eligible dependents and beneficiaries with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan and to the same extent such credit was provided to him or her under the corresponding welfare Company Benefit Plan in which he or she participated immediately prior to the Changeover Time, in each case without duplication of benefits.

(e) Notwithstanding anything herein to the contrary, Parent, Merger Sub and the Company acknowledge and agree that none of the provisions contained in this Agreement (i) shall be treated as an amendment or other modification of any Company Benefit Plan or other employee benefit plan, agreement or other arrangement, (ii) shall (except as set forth in Section 6.5(c)) limit the right of Parent, the Company or their respective Affiliates to amend, terminate or otherwise modify any Company Benefit Plan or Parent Plan following the Changeover Time or (iii) shall be construed to create a right with any employee of the Company or any of its Affiliates to employment with Parent, the Surviving Corporation or any of their respective Affiliates.

(f) The Company agrees that as soon as reasonably practical following the date of this Agreement, it will issue a notification and notice of cancellation of options in the form agreed with Parent to all holders of options under the UK Savings Related Share Option Scheme.

6.6Indemnification; Advancement of Expenses; Exculpation and Insurance.

(a) Each of Parent, Holding and the Surviving Corporation agrees that, to the fullest extent permitted under applicable Law, all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time (including any matter in connection with the Transactions), now existing in favor of the current or former directors, officers or employees of the Company or any of its Subsidiaries or fiduciaries of the Company or any of its Subsidiaries under benefit plans of the Company and its Subsidiaries (collectively, the “Indemnified Parties”), as provided in the Organizational Documents or other indemnification agreements that have been filed as exhibits to the Company SEC Reports in effect as of the date hereof shall survive the Merger and shall continue in full force and effect in accordance with their terms.

(b) From and after the Changeover Time, the Parent shall cause the Surviving Corporation to indemnify and hold harmless each Indemnified Party, and any person who becomes an Indemnified Party between the date hereof and the Effective Time, against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time relating to the Indemnified Party’s service as a director, officer, employee or agent of the Company or the Surviving Corporation or the Indemnified Party’s service at the request of the Company or the Surviving Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, whether asserted or claimed prior to, at or after the Effective Time (including any matters arising in connection with the Transactions), to the fullest extent permitted by applicable Law (and Parent shall cause the Surviving Corporation to advance expenses as incurred to the fullest extent permitted under applicable Law,provided that if required by applicable Law, the person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification).

(c) For a period of six (6) years from and after the Effective Time, Parent shall cause the Surviving Corporation to maintain in effect (A) the current provisions regarding indemnification of and the advancement of expenses to Indemnified Parties contained in the Organizational Documents (or comparable organizational documents) of each of the Company and its Subsidiaries and (B) any indemnification agreements of the Company and its Subsidiaries with or for the benefit of any Indemnified Parties existing on the date hereof. For purposes of the foregoing: (i) in the event any claim is asserted within the six-year period during which the Surviving Corporation is required to maintain the indemnification arrangements of the Company and its Subsidiaries, (A) all such rights in respect of any such claim shall continue until disposition thereof and (B) the Indemnified Party shall be entitled to advancement of expenses within five (5) Business Days following receipt of any such claim for expenses involving such Indemnified Party; and (ii) any determination required to be made with respect to whether an Indemnified Party’s conduct complies with the standards set forth under the DGCL,

the Organizational Documents (or the organizational documents of the Surviving Corporation) or any such agreement, as the case may be, for purposes of the allowance of indemnification or advancement of expenses, shall be made by independent legal counsel selected by such Indemnified Party and reasonably acceptable to Parent. The fees and expenses of such independent legal counsel shall be paid for by the Surviving Corporation.

(d) The Company shall obtain, on or prior to the Acceptance Time, a six year-”tail” prepaid policy on terms and conditions no less advantageous to the Indemnified Parties, or any other person entitled to the benefit of this Section 6.6 as applicable, than the existing directors’ and officers’ liability insurance and fiduciary insurance maintained by the Company, covering, without limitation, claims arising from facts or events that occurred on or before the Effective Time, including the transactions contemplated hereby;provided, that, the cost of such six year-”tail” prepaid policy shall not exceed 300% of the current annual premiums paid by the Company for its existing directors’ and officers’ liability insurance. Parent shall cause the Surviving Corporation after the Effective Time, to maintain such policy in full force and effect, for its full term, and to continue to honor its respective obligations thereunder. From and after the Acceptance Time, neither Parent, the Surviving Corporation nor the Company shall take any action that would prejudice the rights of, or otherwise impede recovery by, the beneficiaries of any insurance policy contemplated by this Section 6.6(d), whether in respect of claims arising before or after the Effective Time.

(e) The obligations of Parent, Holding and the Surviving Corporation under this Section 6.6 shall not be terminated or modified by such parties in a manner so as to adversely affect any of the Indemnified Parties, or any other person entitled to the benefit of this Section 6.6, to whom this Section 6.6 applies without the consent of the affected Indemnified Party or such other person, as the case may be. If the Surviving Corporation or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation, as the case may be, shall assume all of the obligations set forth in this Section 6.6.

(f) The provisions of this Section 6.6 are (i) intended to be for the benefit of, and will be enforceable by, each of the Indemnified Parties and each other person entitled to the benefit of this Section 6.6, his or her heirs and his or her Representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise.

6.7Public Announcements. The Company and Parent each shall consult with the other prior to issuing any press releases or otherwise making public announcements with respect to the Offer, the Merger and the other Transactions and prior to making any filings with any third party and/or any Governmental Entity with respect thereto, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or national market system on which such party’s securities are listed or traded, in which case the party required to make the release or announcement shall consult with the other to the extent practicable. The parties agree that the initial press release to be issued with respect to the Transactions shall be in a form mutually agreed to by the parties.

6.8Section 16 Matters. Prior to the Effective Time, the Company shall be permitted to take any such steps as may be reasonably necessary or advisable to cause any dispositions of Shares (including derivative securities with respect to Shares) resulting from the Transactions 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 promulgated under the Exchange Act, such steps to be taken in accordance with the No Action Letter dated January 12, 1999, issued by the SEC to Skadden, Arps, Slate, Meagher & Flom LLP.

Parent shall cause the Surviving Corporation to honor the obligations of the Company pursuant to the terms of the Convertible Notes, including, if applicable, by providing any required notice under the indentures governing the Convertible Notes as a result of the Transactions to the holders of such Convertible Notes and paying to the holders of such Convertible Notes any amounts that become payable thereunder or by taking such other action as may be required under the terms thereof. In furtherance of the foregoing, if necessary, Parent shall cause the Surviving Corporation to execute one or more supplemental indentures and such other documents, instruments and agreements as may be necessary under the indentures governing the Convertible Notes evidencing the Surviving Corporation’s commitments under this Section 6.9.

Parent and the Surviving Corporation or the Company, as applicable, shall use their respective commercially reasonable best efforts to cause the cash payments required pursuant to this Section 6.10(a) to be paid as soon as practicable after the Acceptance Time in accordance with the currently existing payroll practices of the Company. All amounts payable pursuant to this Section 6.10(a) shall be subject to and reduced by the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 3.2(i) of this Agreement. As of the Acceptance Time, all Company Options shall no longer be outstanding and shall automatically cease to exist, and each holder of a Company Option shall cease to have any rights with respect thereto, except the right to receive the Option Cash Payment. In order to effect the provisions of this Section 6.10(a), the Company shall be permitted to fully accelerate the vesting of all Company Options at such time prior to the Acceptance Time as shall be determined by the Company in its sole discretion.

(b)Restricted Stock. Each award entitling the recipient to receive, upon vesting, Shares granted under an Equity Compensation Plan, that is outstanding immediately prior to the Acceptance Time shall become fully vested on an accelerated basis immediately prior to the Acceptance Time.

(c)Restricted Stock Units. Each restricted stock unit award entitling the recipient to receive, upon vesting, Shares granted under an Equity Compensation Plan (“Company RSU”), that is outstanding immediately prior to the Acceptance Time shall, by virtue of the Acceptance Time and without any action on the part of any holder of any Company RSU, be cancelled, as of the Acceptance Time, in exchange for the right to receive from Parent or Merger Sub, a lump sum cash payment, without interest, equal to the product obtained by multiplying (x) the Offer Price by (y) the number of Shares underlying such Company RSU. Parent and the Surviving Corporation or the Company, as applicable, shall use their respective commercially reasonable best efforts to cause the lump sum payments required pursuant to this Section 6.10(c) to be paid as soon as practicable after the Acceptance Time in accordance with the currently existing payroll practices of the Company (but in any event within the period required by Section 409A of the Code, such that it qualifies as a “short-term deferral” pursuant to Section 1.409A-1(b)(4) of the Treasury Regulations). All amounts payable pursuant to this Section 6.10(c) shall be subject to and reduced by the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 3.2(h) of this Agreement.

(d)Deferred Stock Units. Each deferred stock unit award entitling the recipient to receive, upon the date elected by the recipient, Shares granted under an Equity Compensation Plan (“Company DSU”), that is outstanding immediately prior to the Acceptance Time shall, as of the Acceptance Time and without any action on the part of any holder of any Company DSU, be fully vested and converted into the right to receive from Parent or Merger Sub, a lump sum cash payment, without interest, equal to the product obtained by multiplying (x) the Offer Price by (y) the number of Shares underlying such Company DSU. Parent and the Surviving Corporation or the Company, as applicable, shall cause the lump sum cash payments with respect to the Company DSUs to be paid in accordance with the applicable election of the recipient and in a manner which complies with the requirements of Section 409A of the Code. All amounts payable pursuant to this Section 6.10(d) shall be subject to and reduced by the amount of any withholding and/or deduction that is required under applicable Tax Law in accordance with Section 3.2(h) of this Agreement.

The Company shall take all necessary action to provide that no person will have any further right to purchase Shares under the US ESPP following the Acceptance Time and that the US ESPP shall be suspended with respect to new offerings effective as of the date of this Agreement and terminate effective immediately following the final purchase under the US ESPP described herein.

(f) Any notices or other communications provided pursuant to this Section 6.10 will be provided to Parent in advance of its distribution.

(i) Parent, Holding or Merger Sub shall have breached or failed to perform, in any material respect, any of its representations, warranties, covenants or agreements set forth in this Agreement, which breach or failure to perform (A) would give rise to the failure of a condition set forth in Section 7.1 orAnnex I of this Agreement that has not been waived by Parent and (B) is incapable of being cured (or is not cured) by Parent within thirty (30) calendar days following receipt of written notice of such breach or failure to perform from the Company,provided,however, that the failure of any such condition to be capable of satisfaction is not the result of a material breach of this Agreement by the Company;

there shall be any statute, rule, regulation or order enacted, entered, enforced, promulgated or which is deemed applicable pursuant to an authoritative interpretation by or on behalf of a Government Entity of competent jurisdiction to the Offer, the Merger or any other transaction contemplated by the Merger Agreement, or any other action shall be taken by any Governmental Entity that (x) is, in the reasonable judgment of Parent and Merger Sub, reasonably expected to result, directly or indirectly, in any of the consequences referred to in paragraph 1 above, or (y) has the effect of making the Offer, the Merger or any other transaction contemplated by the Merger Agreement illegal or which has the effect of prohibiting or otherwise preventing the consummation of the Offer, the Merger or any other transaction on the terms contemplated by the Merger Agreement;

(i) any representation or warranty of the Company contained in the second, sixth (but only as to the aggregate number of Shares issuable pursuant to the plans and arrangements referred to) and seventh sentences of Section 4.1(b) (in each case as updated by the last sentence of Section 4.1(b)) shall not be true and correct in all but de minimis respects at any time from and after the date of this Agreement (except for any such representation or warranty made as of a specified date, which shall not be true and correct in all but de minimis respects as of such date), (ii) any of the representations and warranties of the Company contained in Sections 4.1(j) [Voting Requirements], (k) [Anti-Takeover Statutes] or (n) [Stockholder Rights Agreement Amended] shall not be true and correct in all material respects at any time from and after the date of this Agreement, or (iii) any other representation or warranty of the Company contained in the Agreement (without giving effect to any references to any Company Material Adverse Effect or

Meetings of stockholders for any purpose may be held at such time and place within or without the State of Delaware as the Board may fix from time to time and as shall be stated in the notice of the meeting or in a duly executed waiver of notice thereof.

Section 2.2Annual Meeting. Annual meetings of stockholders shall be held at such date and time as shall be designated from time to time by the Board and stated in the notice of the meeting. At such annual meetings, the stockholders shall elect a Board and transact such other business as may properly be brought before the meetings.

Section 2.3Special Meetings. Special meetings of the stockholders may be called for any purpose or purposes, unless otherwise prescribed by the statute or by the Certificate of Incorporation, at the request of the Board, the Chairman of the Board, the President or the holders of shares entitled to cast not less than ten percent (10%) of the votes at the meeting or such additional persons as may be provided in the Certificate of Incorporation or these Bylaws. Such request shall state the purpose or purposes of the proposed meeting. Upon request in writing that a special meeting of stockholders be called for any proper purpose, directed to the Chairman of the Board, the President, a Vice President or the Secretary by any person (other than the Board) entitled to call a special meeting of stockholders, the person forthwith shall cause notice to be given to the stockholders entitled to vote that a meeting will be held at a time requested by the person or persons calling the meeting, such time not to be less than ten (10) nor more than sixty (60) days after receipt of the request.

At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

(a) Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the corporation under any provision of Delaware General Corporation Law, the certificate of incorporation, or these bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice to the corporation. Any such consent shall be deemed revoked if (i) the corporation is unable to deliver by electronic transmission two consecutive notices given by the corporation in accordance with such consent, and (ii) such inability becomes known to the secretary or an assistant secretary of the corporation or to the transfer agent or other person responsible for the giving of notice; provided, however, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

In the absence of the Secretary of the Corporation, the Secretary of the meeting shall be such person as the Chairman appoints.

The Chairman of any meeting of stockholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seems to him or her in order.

Except where otherwise provided by law or the Certificate of Incorporation or these Bylaws, the holders of a majority of the stock issued and outstanding and entitled to vote, present in person or represented in proxy, shall constitute a quorum at all meetings of the stockholders. The stockholders present at a duly called or held meeting at which a quorum is present may continue to do business until adjournment, notwithstanding the withdrawal of enough stockholders to have less than a quorum if any action taken (other than adjournment) is approved by at least a majority of the shares required to constitute a quorum. At such adjourned meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. If, however, a quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat who are present in person or represented by proxy shall have the power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented.

Section 2.10Majority Vote. When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which by express provision of the statutes or of the Certificate of Incorporation or of these Bylaws, a different vote is required in which case such express provision shall govern and control the decision of such question.

Section 2.11Record Date for Stockholder Notice and Voting. For purposes of determining the stockholders entitled to notice of any meeting or to vote, or entitled to receive payment of any dividend or other distribution, or entitled to exercise any right in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix, in advance, a record date, which shall not be more than sixty (60) days nor less than ten (10) days before the date of any such meeting nor more than sixty (60) days before any other action.

If the Board does not so fix a record date, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the business day next preceding the day on which notice is given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held.

Section 2.12Proxies. Every person entitled to vote for directors or on any other matter shall have the right to do so either in person or by one or more agents authorized by a written proxy signed by the person and filed with the Secretary of the Corporation.

The number of inspectors shall be either one (1) or three (3). If inspectors are appointed at a meeting on the request of one or more stockholders or proxies, the holders of a majority of shares or their proxies present at the meeting shall determine whether one (1) or three (3) inspectors are to be appointed.

If a quorum is not present at any meeting of the Board, the directors present may adjourn the meeting from time to time, without notice other than announcement at the meeting at which the adjournment is taken, until a quorum shall be present. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved of by at least a majority of the required quorum for that meeting.

Section 3.10Action Without Meeting. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if all members of the Board or committee, as the case may be, consent thereto in writing or by electronic transmission, and such writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

Notice of a meeting need not be given to any director who signs a waiver of notice or a consent to holding the meeting or an approval of the minutes thereof, whether before or after the meeting, or who attends the meeting without protesting, prior thereto or at its commencement, the lack of notice to such director. All such waivers, consents and approvals shall be filed with the corporate records or made a part of the minutes of the meeting.

Section 3.13Fees and Compensation of Directors. Directors and members of committees may receive such compensation, if any, for their services, and such reimbursement for expenses, as may be fixed or determined by resolution of the Board of Directors. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings.

Section 3.14Rights of Inspection. Every director shall have the absolute right at any reasonable time to inspect and copy all books, records and documents of every kind and to inspect the physical properties of the Corporation and also of its subsidiary corporations, domestic or foreign.
