ARTICLE 2

The Offer

Section 2.01. The Offer. (a) As promptly as practicable after the date hereof, but in no event later than ten Business Days following the date of this Agreement, Merger Subsidiary shall, and Parent shall cause it to, commence (within the meaning of Rule 14d-2 under the ▇▇▇▇ ▇▇▇) the Offer. The Offer shall be subject to the conditions set forth in Annex I hereto (the “Offer Conditions”). The date on which Merger Subsidiary commences the Offer is referred to as the “Offer Commencement Date”.

(b) Subject to the terms and conditions set forth in this Agreement and to the satisfaction or waiver of the Offer Conditions, Merger Subsidiary shall, and Parent shall cause it to, promptly after the Expiration Date, accept for payment all Shares validly tendered and not validly withdrawn pursuant to the Offer (the time at which Shares are first accepted for payment pursuant to and subject to the terms and conditions of the Offer, the “Acceptance Time”). The obligation of Merger Subsidiary to accept for payment and pay for any Shares validly tendered and not validly withdrawn pursuant to the Offer shall be subject to: (i) the number of Shares validly tendered in the Offer and not validly withdrawn prior to any then-scheduled Expiration Date representing, together with the Contributed Shares and the Shares beneficially owned by Parent or Merger Subsidiary (if any), at least 67.2% of the Shares outstanding on a fully-diluted basis as of the Expiration Date (the “Minimum Tender Condition”); (ii) the applicable waiting period under the HSR Act shall have expired or been terminated (the “HSR Act Condition”) and (iii) the satisfaction or, to the extent permissible, waiver by Parent or Merger Subsidiary of each of the other Offer Conditions. Promptly (within the meaning of Section 14e-1(c) under the ▇▇▇▇ ▇▇▇) after the Acceptance Time, Merger Subsidiary shall pay the Offer Price for such Shares. The date of acceptance for payment of Shares pursuant to and subject to the conditions of the Offer is referred to in this Agreement as the “Offer Closing,” and the date on which the Offer Closing occurs is referred to in this Agreement as the “Offer Closing Date.” The Offer Price payable in respect of each Share validly tendered and not validly withdrawn pursuant to the Offer shall be paid net to the seller in cash, without interest, on the terms and subject to the conditions set forth in this Agreement.

(c) Parent and Merger Subsidiary expressly reserve the right to waive any of the Offer Conditions and to make any change in the terms of or conditions to the Offer (including raising the Offer Price); provided that, without the prior written consent of the Company or unless otherwise expressly contemplated by this Agreement, neither Parent nor Merger Subsidiary shall:

(i) waive or change the Minimum Tender Condition;

(ii) decrease the Offer Price;

(iii) change the form of consideration to be paid in the Offer;

(iv) decrease the number of Shares sought in the Offer;

(v) extend or otherwise change the expiration date of the Offer except as otherwise provided herein; or

(vi) impose additional Offer Conditions or otherwise amend, modify or supplement any of the Offer Conditions or terms of the Offer in a manner materially adverse to the holders of the Shares.

(d) The Offer shall initially be scheduled to expire on the date that is 20 business days (calculated as set forth in Rule 14d-l(g)(3) under the ▇▇▇▇ ▇▇▇) after the Offer Commencement Date (the “Initial Expiration Date”). The date on which the Offer finally expires (taking into account any extensions that may be elected or required pursuant to and in accordance with this Section 2.01(d)) is referred to herein as the “Expiration Date.” Notwithstanding the foregoing, if at any then-scheduled expiration of the Offer (including the Initial Expiration Date), (i) Merger Subsidiary shall, and Parent shall cause it to, extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or Nasdaq applicable to the Offer or for any period otherwise required by Applicable Law; (ii) Merger Subsidiary may, and, if requested by the Company, shall, extend the Offer for one or more periods if any Offer Condition is not satisfied and has not been waived; provided, however, that Merger Subsidiary shall not have the right to extend the Offer pursuant to this clause (ii) (A) beyond the earlier of (x) December 5, 2012 and (y) the date that is five Business Days following the Proxy Statement Clearance Date, or (B) if such extension is prohibited by any Applicable Law or any rule, regulation, interpretation or position of the SEC or Nasdaq; and (iii) Merger Subsidiary may extend the Offer if, at the date upon which the Offer is scheduled to expire, all of the Offer Conditions have been satisfied or waived and the Initial Marketing Period has not ended as of the last Business Day prior to such scheduled expiration date until the earliest to occur of (1) the first Business Day after the Debt Providers have waived the condition in the Debt Commitment Letter relating to the Initial Marketing Period and (2) the first Business Day after the final day of the Initial Marketing Period. The Offer may be terminated prior to the Expiration Date if this Agreement is terminated pursuant to Article 11.

(e) If (i) at any then-scheduled Expiration Date (including the Initial Expiration Date), any Offer Condition shall not have been satisfied or waived and no further extensions or re-extensions are required or permitted pursuant to Section 2.01(d) or (ii) five Business Days have elapsed since the Proxy Statement Clearance Date, then Merger Subsidiary may irrevocably and unconditionally terminate the Offer. If (A) this Agreement is terminated pursuant to Article 11 or (B) there shall exist a Top-Up Impediment and Merger Subsidiary elects to terminate the Offer, then, in each case, Merger Subsidiary shall promptly irrevocably and unconditionally terminate the Offer. The parties hereto

acknowledge and agree that the termination of the Offer shall not give rise to a right of termination of this Agreement except as expressly provided for herein and that, absent any such termination of this Agreement, the obligations of the parties hereunder other than those related to the Offer shall continue to remain in effect, including those obligations with respect to the Merger.

(f) As soon as practicable on the Offer Commencement Date, Parent and Merger Subsidiary shall (i) file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments and supplements thereto and including exhibits thereto, the “Schedule TO”) that shall include the summary term sheet required thereby and, as exhibits, the Offer to Purchase and a form of letter of transmittal and summary advertisement (collectively, together with any amendments or supplements thereto, the “Offer Documents”) and (ii) cause the Offer Documents to be disseminated to holders of Shares to the extent required by Applicable Law (including the 1934 Act). Parent and Merger Subsidiary shall cause the Offer Documents to (A) comply with the applicable requirements of the 1934 Act and (B) 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; provided, however, no covenant, representation or warranty is made by Parent or Merger Subsidiary with respect to information supplied by the Company for inclusion in the Offer Documents. Parent and Merger Subsidiary shall cause the information supplied by Parent and its Affiliates specifically for inclusion in the Company’s Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, the “Schedule 14D-9”), at the time the Schedule 14D-9 is filed with the SEC, 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. Each of Parent, Merger Subsidiary and the Company agrees promptly to correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become (or shall have become known to be) false or misleading in any material respect. Parent and Merger Subsidiary shall use their reasonable best efforts to cause the Offer Documents as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case to the extent required by Applicable Law. The Company and its counsel shall be given a reasonable opportunity to review and comment on any Offer Document each time before any such document is filed with the SEC, and Parent and Merger Subsidiary shall give due consideration to any reasonable comments made by the Company and its counsel. Parent and Merger Subsidiary shall provide the Company and its counsel with (1) any comments or other communications, whether written or oral, that Parent, Merger Subsidiary or their counsel may receive from time to time from the SEC or its staff with respect to any of the Offer Documents promptly after receipt of those comments or other communications and (2) a reasonable opportunity to participate in the response of Parent and Merger Subsidiary to those comments and to provide comments on that response (to which due

consideration shall be given to reasonable comments), including by participating with Parent and Merger Subsidiary or their counsel in any discussions or meetings with the SEC. Each of Parent and Merger Subsidiary shall respond as promptly as practicable to any comments of the SEC or its staff with respect to the Offer Documents or the Offer.

Section 2.02. Company Action. (a) The Company hereby consents to the Offer and represents that the board of directors of the Company (the “Board of Directors”), at a meeting duly called and held, has unanimously (i) determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, are advisable, fair to and in the best interests of the Company and the Company’s stockholders; (ii) approved, adopted and declared advisable this Agreement and the transactions contemplated hereby, including the Offer and the Merger, in accordance with the requirements of Delaware Law; (iii) resolved, subject to Section 7.03(b), to recommend that the Company’s stockholders accept the Offer, tender their Shares to Merger Subsidiary in the Offer, and, to the extent applicable, adopt this Agreement and approve the Merger; and (iv) elected that the Offer and the Merger not be subject to any “moratorium,” “control share acquisition,” “business combination,” “fair price” or other form of anti-takeover laws of any jurisdiction that may purport to be applicable to this Agreement or any of the transactions contemplated herein. The Company has been advised that all of its directors and executive officers who own Shares intend to tender their Shares pursuant to the Offer. The Company shall promptly furnish Parent with a list of its stockholders, 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 true and correct as of the most recent practicable date, and shall provide to Parent 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 or the Merger.

(b) As soon as practicable on the Offer Commencement Date, the Company shall file with the SEC and disseminate to holders of Shares, in each case as and to the extent required by Applicable Law, the Schedule 14D-9 that, subject to Section 7.03(b), shall reflect the recommendations of the Board of Directors referred to above. The Company shall also include in the Schedule 14D-9, in its entirety, the Fairness Opinion, together with a summary thereof in accordance with Item 1015(b) of Regulation M-A under the 1934 Act (regardless of whether such item is applicable). The Company hereby consents to the inclusion in the Offer Documents of a description of the Company Board Recommendation. The Company shall cause the Schedule 14D-9 to (i) comply with the applicable requirements of the 1934 Act and (ii) not (A) contain any untrue statement of a material fact or (B) 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; provided, that no covenant is made by the Company with respect to information supplied by Parent or Merger Subsidiary specifically for inclusion in the Schedule 14D-9

(including any such information included in the Company Proxy Statement). The Company shall cause the information supplied by it specifically for inclusion in the Offer Documents, at the respective times the Offer Documents are filed with the SEC, 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. Each of the Company, Parent and Merger Subsidiary agrees promptly to correct any information supplied by it specifically for inclusion in the Schedule 14D-9 if and to the extent that it shall have become (or shall have become known to be) false or misleading in any material respect. The Company shall use its reasonable best efforts to cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case to the extent required by Applicable Law. Parent, Merger Subsidiary and their counsel shall be given a reasonable opportunity to review and comment on the Schedule 14D-9 each time before it is filed with the SEC, and the Company shall give reasonable and good faith consideration to any comments made by Parent, Merger Subsidiary and their counsel. The Company shall provide Parent, Merger Subsidiary and their counsel with (1) any comments or other communications, whether written or oral, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of those comments or other communications, and (2) a reasonable opportunity to participate in the Company’s response to those comments and to provide comments on that response (to which due consideration shall be given to reasonable comments), including by participating with the Company or its counsel in any discussions or meetings with the SEC. The Company shall respond as promptly as practicable to any comments to the SEC with respect to the Schedule 14D-9.

(c) The Company shall as promptly as practicable furnish to Parent and Merger Subsidiary all information concerning the Company that may be required by Applicable Law or reasonably requested by Parent or Merger Subsidiary specifically for inclusion in the Offer Documents.

Section 2.03. Directors. (a) Effective upon the Acceptance Time, Parent shall be entitled to designate the number of directors, rounded up to the next whole number, on the Board of Directors that equals the product of (i) the total number of directors on the Board of Directors (giving effect to the election of any additional directors pursuant to this Section); and (ii) the percentage that the number of Shares beneficially owned by Parent and/or Merger Subsidiary (including Shares accepted for payment), together with the Contributed Shares, bears to the total number of Shares outstanding, and the Company promptly shall cause Parent’s designees to be elected or appointed to the Board of Directors, including by increasing the number of directors, and seeking and accepting resignations of incumbent directors or amending the Company’s bylaws as is necessary to give effect to the foregoing provision; provided that until the Effective Time, at least two Independent Directors shall remain on the Board of Directors. At such time, the Company shall also cause individuals designated by

Parent to constitute the number of members, rounded up to the next whole number, on (A) each committee of the Board of Directors and (B) as requested by Parent, each board of directors of each Subsidiary of the Company (and each committee thereof) that represents the same percentage as such individuals represented on the Board of Directors. Except as provided in the first and second sentences of this Section 2.03(a), the Company shall use its reasonable best efforts to ensure that all of the members of the Board of Directors and such committees and boards as of the date hereof who are not employees of the Company remain members of the Board of Directors and such committees and boards.

(b) The Company’s obligations to appoint Parent’s designees to the Board of Directors shall be subject to Section 14(f) of the 1934 Act and Rule 14f-1 promulgated thereunder. The Company shall promptly take all actions, and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors, as Section 14(f) of the 1934 Act and Rule 14f-1 promulgated thereunder require in order to fulfill its obligations under this Section. 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) of the 1934 Act and Rule 14f-1 promulgated thereunder.

(c) Following the election or appointment of Parent’s designees pursuant to Section 2.03(a) and until the Effective Time, the approval of a majority of the directors of the Company then in office who were not designated by Parent (the “Independent Directors”) shall be required to authorize (and such authorization shall constitute the authorization of the Board of Directors and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) any termination of this Agreement by the Company, any amendment of this Agreement requiring action by the Board of Directors, any extension of time for performance of any obligation or action hereunder by Parent or Merger Subsidiary, and any waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company.

Section 2.04. Top-Up Option. (a) Subject to Section 2.04(b) and Section 2.04(c), the Company grants to Merger Subsidiary an irrevocable option, for so long as this Agreement has not been terminated pursuant to the provisions hereof (the “Top-Up Option”), to purchase from the Company up to the number of Shares equal to the number of Shares that, when added to the number of Shares owned by Merger Subsidiary at the time of the exercise of the Top-Up Option, together with the Contributed Shares, constitutes at least 90% of the Shares outstanding on the Offer Closing Date, on a fully-diluted basis (such Shares to be issued upon exercise of the Top-Up Option, the “Top-Up Shares”); provided that the Top-Up Option shall not be exercisable to the extent (i) the number of Shares issuable upon exercise of the Top-Up Option would exceed the number of authorized but unissued and unreserved Shares plus the number of Shares held as treasury shares or (ii) any provision of Applicable Law would prohibit the

exercise of the Top-Up Option or the delivery of the Top-Up Shares with respect to such exercise.

(b) Subject to Section 9.01(a), the Top-Up Option may be exercised by Merger Subsidiary in whole or in part, only once, at any time during the 10 Business Day period following the Acceptance Time, and only if Merger Subsidiary shall own, together with the Contributed Shares, as of such time less than 90% of the Shares outstanding on a fully-diluted basis. The aggregate purchase price payable for the Top-Up Shares being purchased by Merger Subsidiary pursuant to the Top-Up Option shall be determined by multiplying the number of such Top-Up Shares by the Offer Price, without interest. Such purchase price may be paid by Merger Subsidiary, at its election, either (i) entirely in cash or (ii) by paying in cash an amount equal to not less than the aggregate par value of such Top-Up Shares and by executing and delivering to the Company a promissory note having a principal amount equal to the balance of such purchase price. Any such promissory note (A) shall bear interest at the rate of 3% per annum, (B) shall mature on the first anniversary of the date of execution and delivery of such promissory note, (C) may be prepaid without premium or penalty, (D) shall be full recourse to Parent and Merger Subsidiary, and (E) shall have no other material terms. The Company shall include in the Schedule 14D-9 a description of the material terms of the Top-Up Option, including the terms of any such promissory note.

(c) In the event Merger Subsidiary exercises the Top-Up Option, Merger Subsidiary shall deliver to the Company a notice (the “Top-Up Notice”) setting forth (i) that Merger Subsidiary is exercising the Top-Up Option; (ii) the manner in which Merger Subsidiary intends to pay the applicable purchase price; and (iii) the place and time at which the closing of the purchase of such Top-Up Shares by Merger Subsidiary (the “Top-Up Closing”) is to take place. The Company shall, as soon as practicable following receipt of such notice, deliver written notice to Parent and Merger Subsidiary specifying the number of Shares then outstanding and, based on such number and based on the information provided by Merger Subsidiary in the Top-Up Notice, the number of Top-Up Shares to be purchased. The Company shall make available to Parent and Merger Subsidiary all information reasonably requested to enable Parent and Merger Subsidiary to independently verify and calculate the number of Shares necessary for Merger Subsidiary to be merged into the Company without a vote or consent of the Company’s stockholders in accordance with Section 253 of Delaware Law. The Top-Up Notice shall also include an undertaking signed by Parent and Merger Subsidiary that, as promptly as practicable following such exercise of the Top-Up Option, Merger Subsidiary intends to (and Merger Subsidiary shall, and Parent shall cause Merger Subsidiary to, as promptly as practicable after such exercise) consummate the Merger in accordance with Section 253 of Delaware Law as contemplated by Section 9.01(e). At the Top-Up Closing, Parent and Merger Subsidiary shall cause to be delivered to the Company the consideration required to be delivered in exchange for the Top-Up Shares, and the Company shall cause to be issued to Merger Subsidiary a certificate representing the Top-

Up Shares. The parties hereto agree to use their reasonable best efforts to cause the Top-Up Closing to occur on the same day that the Top-Up Notice is deemed received by the Company pursuant to Section 12.01, and if not so consummated on such day, as promptly thereafter as possible. The parties further agree to use their reasonable best efforts to cause the Merger to be consummated in accordance with Section 253 of Delaware Law as contemplated by Section 9.01(e) as close in time as possible to (including, to the extent possible, on the same day as) the issuance of the Top-Up Shares.

(d) Parent and Merger Subsidiary understand that the Top-Up Shares will not be registered under the 1933 Act and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Each of Parent and Merger Subsidiary represents, warrants and agrees that the Top-Up Option is being, and the Top-Up Shares will be, acquired by Merger Subsidiary for the purpose of investment and not with a view to or for resale in connection with any distribution thereof within the meaning of the 1933 Act. Any certificates evidencing Top-Up Shares shall include any legends required by applicable securities laws.

(e) To the fullest extent permitted by Applicable Law, any dilutive impact on the value of the Shares as a result of the Top-Up Option, the issuance of the Top-Up Shares or the payment by Merger Subsidiary to the Company of any consideration for the Top-Up Shares will not be taken into account in any determination of the fair value of any dissenting Shares in any appraisal proceeding pursuant to Section 262 of Delaware Law as contemplated by Section 3.04.

ARTICLE 3

The Merger

Section 3.01. The Merger. (a) Subject to the terms and conditions set forth in this Agreement, at the Effective Time, Merger Subsidiary shall be merged (the “Merger”) with and into the Company in accordance with Delaware Law, whereupon the separate existence of Merger Subsidiary shall cease, and the Company shall be the surviving corporation (the “Surviving Corporation”).

(b) Subject to the provisions of Article 10, the closing of the Merger (the “Closing”) shall take place (i) if the Offer Closing shall not have occurred prior to the Closing, as soon as possible, but in any event no later than two Business Days after the date the conditions set forth in Article 10 (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permissible, waiver of those conditions at the Closing) have been satisfied or, to the extent permissible, waived by the party or parties entitled to the benefit of such conditions (such date being the “First Eligible One-Step Closing Date”), or (ii) if the Offer Closing shall have occurred on or prior to the Closing, on the date of, and immediately following the later to occur

of (A) the Offer Closing and (B) the Top-Up Closing (if applicable), in each case at the offices of ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇▇▇, or at such other place, at such other time or on such other date as Parent and the Company may agree. Notwithstanding the preceding sentence, if the Offer Closing shall not have occurred prior to the Closing, at the option of Parent the Closing may take place on either (x) a Business Day on or after the First Eligible One-Step Closing Date during the One-Step Marketing Period to be specified by Parent on no less than three Business Days’ notice to the Company or (y) the Business Day after the final day of the One-Step Marketing Period.

(c) At the Closing, the Company and Merger Subsidiary shall file a certificate of merger with the Delaware Secretary of State and make all other filings or recordings required by Delaware Law in connection with the Merger. The Merger shall become effective at such time (the “Effective Time”) as the certificate of merger is duly filed with the Delaware Secretary of State (or at such later time as may be agreed upon by Parent, Merger Subsidiary and the Company and specified in such certificate of merger).

(d) From and after the Effective Time, the Surviving Corporation shall possess all the properties, rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of the Company and Merger Subsidiary, in each case as provided under Delaware Law.

Section 3.02. Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Subsidiary or any holder of securities thereof:

(a) Except as otherwise provided in Section 3.02(b), Section 3.02(c) or Section 3.04, each Share outstanding immediately prior to the Effective Time shall be converted into the right to receive the Offer Price in cash, without interest (the “Merger Consideration”). As of the Effective Time, all such Shares shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and shall thereafter represent only the right to receive the Merger Consideration.

(b) Each Share held by the Company as treasury stock (other than Shares in an Employee Plan of the Company) or owned by Parent or Merger Subsidiary (including the Contributed Shares) immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto.

(c) Each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Section 3.03. Surrender and Payment. (a) Prior to the Effective Time, Parent shall appoint an agent reasonably acceptable to the Company (the “Paying Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing Shares (the “Certificates”) or (ii) uncertificated Shares (the “Uncertificated Shares”). Immediately prior to the Effective Time, Parent shall make available to the Paying Agent the Merger Consideration to be paid in respect of the Shares. Promptly after the Effective Time (but not later than five Business Days thereafter), Parent shall send, or shall cause the Paying Agent to send, to each holder of Shares at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Paying Agent) for use in such exchange.

(b) Each holder of Shares that have been converted into the right to receive the Merger Consideration shall be entitled to receive, upon (i) surrender to the Paying Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Merger Consideration payable for each Share represented by a Certificate or for each Uncertificated Share. Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Share shall represent after the Effective Time for all purposes only the right to receive the Merger Consideration.

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred; and (ii) the Person requesting such payment shall pay to the Paying Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Paying Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no further registration of transfers of Shares. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this Article 3.

(e) Any portion of the Merger Consideration made available to the Paying Agent pursuant to Section 3.03(a) (and any interest or other income earned thereon) that remains unclaimed by the holders of Shares twelve months after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged such Shares for the Merger Consideration in accordance with this Section 3.03 prior to that time shall thereafter look only to Parent for payment only as general creditors thereof of the Merger Consideration in respect

of such Shares without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation or the Paying Agent shall be liable to any holder of Shares for any amount paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of Shares twenty-four months after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Applicable Law, the property of Parent, free and clear of any claims or interests of any Person previously entitled thereto.

Section 3.04. Dissenting Shares. Notwithstanding Section 3.02, Shares outstanding immediately prior to the Effective Time and held by a holder who (a) has not voted in favor of the Merger or consented thereto in writing and (b) has demanded appraisal for such Shares in accordance, and in compliance in all respects, with Section 262 of Delaware Law shall not be converted into the right to receive the Merger Consideration, and shall instead represent the right to receive payment of the fair value of such Shares in accordance with, and to the extent provided by, Section 262 of Delaware Law, unless such holder fails to perfect, withdraws or otherwise loses the right to appraisal. If, after the Effective Time, such holder fails to perfect, withdraws or otherwise loses the right to appraisal, then the right of such holder to be paid the fair value thereof shall cease and such Shares shall be treated as if they had been converted as of the Effective Time into the right to receive the Merger Consideration. The Company shall give Parent prompt notice of any demands received by the Company for appraisal of Shares, and Parent shall have the right to direct all negotiations and Proceedings with respect to such demands. Except with the prior written consent of Parent, the Company shall not make any payment with respect to, or offer to settle or settle, any such demands.

Section 3.05. Company Stock Options. (a) At or immediately prior to the Effective Time, each option to acquire Shares granted or issued pursuant to any Company Stock Plan that is outstanding immediately prior to the Effective Time (collectively, the “Company Stock Options”), whether or not vested or exercisable, shall be canceled, and, at or promptly after the Effective Time, the Company shall pay each holder of any such cancelled Company Stock Option an amount in cash determined by multiplying (i) the excess, if any, of the Merger Consideration over the applicable exercise price of such cancelled Company Stock Option by (ii) the number of Shares such holder could have purchased (assuming full vesting of all options) had such holder exercised such Company Stock Option in full immediately prior to the Effective Time.

(b) Prior to the Effective Time, the Company shall (i) use its reasonable best efforts to obtain consents from holders of Company Stock Options and (ii) make any amendments to the terms of any Company Stock Plans or Company Stock Options that, in the case of either clauses (i) or (ii), are necessary to give effect to the transactions contemplated by Section 3.05(a); provided that the Company shall not pay any amounts (other than any payments pursuant to Section

3.05(a)) for such consents without the prior written consent of Parent. Notwithstanding any provision of Section 3.05, payment may be withheld in respect of any Company Stock Option until any such consent is obtained with respect to such Company Stock Option.

Section 3.06. Company RSUs.

Copies of such plans, agreements, arrangements, and policies (and, if applicable, related trusts, summary plan descriptions or funding agreements and insurance policies) and all amendments thereto and written interpretations thereof have been made available to Parent, together with the most recent annual report (Form 5500 including, if applicable, Schedule B thereto) and Tax Return (Form 990) prepared in connection with any such plan or trust, funding agreement or insurance policy.

(b) Neither the Company nor any ERISA Affiliate nor any predecessors thereof sponsors, maintains, contributes to or is required to contribute to, and in the past six years has not sponsored, maintained, contributed to or been required to contribute to, any Employee Plan that is subject to Title IV of ERISA.

(c) Neither the Company nor any ERISA Affiliate contributes to or has in the past six years contributed to any multiple employer plan (as described in Section 413(c) of the Code) or multiemployer plan, as defined in Section 3(37) of ERISA.

(d) Each Employee Plan that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter, or has pending or has time remaining in which to file, an application for such determination from the Internal Revenue Service, and the Company has no knowledge of any reason why any such determination letter should be revoked or not issued or such tax-qualified status would be lost. The Company has made available to Parent copies of the most recent Internal Revenue Service determination letters with respect to each such Employee Plan. Except as would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect, (i) each Employee Plan has been maintained in compliance with its terms and with the requirements prescribed by any and all statutes, Orders, rules and regulations, including ERISA and the Code, which are applicable to such Employee Plan; (ii) no event has occurred with respect to any Employee Plan that could result in payment or assessment by or against the Company of any excise taxes under Sections 4972, 4975, 4976, 4977, 4979, 4980B, 4980D, 4980E or 5000 of the Code; and (iii) there has been no breach of any fiduciary duty with respect to any Employee Plan or funding arrangement.

(e) The consummation of the transactions contemplated by this Agreement will not (either alone or together with any other event) entitle any current or former employee, director or independent contractor of the Company to any payment of money or other property, including any bonus or severance, retirement, job security or other material payment or benefit or accelerate the time of payment or vesting or trigger any material payment or funding (through a grantor trust or otherwise) of compensation or benefits under, materially increase the amount payable or trigger any other material obligation pursuant to, any Employee Plan. There is no contract, plan or arrangement (written or otherwise) covering any current or former employee, director or individual independent contractor of the Company that, individually or collectively, could, as a result of the transactions contemplated by this Agreement, give rise to the payment of any amount that would not be deductible pursuant to the terms of Section 280G of the Code or that would be subject to the excise tax under Section 4999 of the Code. No Employee Plan provides for the gross-up or reimbursement of Taxes under Section 4999 or 409A of the Code, or otherwise.

(f) The Company does not have any material liability in respect of post-retirement health, medical or life insurance benefits for retired, former or current employees or individual independent contractors of the Company except as required to avoid excise tax under Section 4980B of the Code.

(g) There has been no amendment to, interpretation or announcement (whether or not written) by the Company relating to, or change in employee

participation or coverage under, an Employee Plan which would increase materially the expense of maintaining such Employee Plan above the level of the expense incurred in respect thereof for the fiscal year ended December 31, 2011.

(h) The Company is not a party to or subject to, or is currently negotiating in connection with entering into, any collective bargaining agreement or other Contract with a labor union or organization.

There are no strikes, slowdowns or work stoppages, pending or, to the knowledge of the Company, threatened against the Company. There are no other employment-related claims, including wrongful termination, discrimination and sexual harassment claims, pending or, to the knowledge of the Company, threatened against the Company, except as would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

(i) All material contributions and payments due or accrued under each Employee Plan, determined in accordance with Applicable Law and GAAP and prior funding and accrual practices, as adjusted to include proportional accruals for the period ending as of the date hereof, have been timely and fully discharged and paid on or prior to the date hereof except to the extent not yet due and then reflected as a liability on the Company Balance Sheet.

(j) There is no Proceeding pending against or involving or, to the knowledge of the Company, threatened against or involving, any Employee Plan.

(k) Except as would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect, each Employee Plan that is a “nonqualified deferred compensation plan” within the meaning of Treasury Regulation § 1.409A-1(a)(l)(a) and subject to Section 409A of the Code (a “Nonqualified Deferred Compensation Plan”) was administered in material compliance with Section 409A of the Code between January 1, 2005 and December 31, 2008, based upon a good faith, reasonable interpretation of Section 409A of the Code and applicable guidance thereunder, and each Nonqualified Deferred Compensation Plan has been maintained and operated in material compliance with Section 409A of the Code since January 1, 2009.

Except for breaches, violations or defaults which have not had and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect, (i) each of the Material Contracts, and any Contract entered into between the date hereof and the Effective Time that would be a Material Contract if entered prior to the date hereof, is valid and in full force and effect, and (ii) the Company has not, and to the Company’s knowledge no other party to a Material Contract, or any Contract entered into between the date hereof and the Effective Time that would be a Material Contract if entered prior to the date hereof has, violated any provision of, or taken or failed to take any act which, with or without notice, lapse of time, or both, would constitute a default under the provisions of such Contract, and the Company has not received notice that it has breached, violated or defaulted under any Material Contract or any Contract entered into between the date hereof and the Effective Time that would be a Material Contract if entered prior to the date hereof.

The Company shall not, and shall cause each of its Affiliates and its and their respective officers, directors, employees, financial advisors, investment bankers, attorneys, accountants, consultants or other agents or advisors (collectively, “Representatives”) not to, directly or indirectly, solicit, initiate or knowingly take any action to facilitate or encourage the submission of any Acquisition Proposal, enter into or participate in any discussions or negotiations with, or furnish any information relating to the Company or afford access to the business, properties, assets, books or records of the Company to or otherwise cooperate in any way with any Third Party that is seeking to make, or has made, an Acquisition Proposal. Neither the Board of Directors nor any committee thereof shall (i) fail to make, withdraw or modify (including in the Schedule 14D-9) in a manner adverse to Parent the Company Board Recommendation, (ii) approve or recommend an Acquisition Proposal, (iii) enter into any agreement in principle, letter of intent, term sheet, merger agreement, acquisition agreement, option agreement or other similar instrument relating to an Acquisition Proposal, or (iv) publicly propose or announce an intention to take any of the foregoing actions (any of the foregoing in clauses (i) through (iv), an “Adverse Recommendation Change”). The Company shall not grant any waiver or release under any standstill, confidentiality or similar provision of any agreement to which the Company is a party, shall enforce to the fullest extent permitted under Applicable Law the standstill provisions of any agreement to which the Company is a party and shall immediately take steps within its power necessary to terminate any waiver that may have been heretofore granted to any Person other than Parent and its Affiliates under any such provisions. Any violation of the restrictions on the Company set forth in this Section 7.03 by any Affiliate or Representative of the Company shall be a breach of this Section 7.03 by the Company.

(b) Exceptions. Notwithstanding Section 7.03(a), at any time from and after the date of this Agreement until the earlier to occur of the Offer Closing and the receipt of the Company Stockholder Approval:

(i) the Company, directly or indirectly through its Representatives, may (A) engage in negotiations or discussions with any Third Party (and its Representatives) that, subject to the Company’s compliance with Section 7.03(a), has made after the date of this Agreement a bona fide, unsolicited written Acquisition Proposal that the Board of Directors determines in good faith, after consultation with outside legal counsel and a financial advisor of nationally recognized reputation, is or would be reasonably likely to result in a Superior

Proposal and (B) furnish to such Third Party (and its Representatives) non-public information relating to the Company pursuant to a confidentiality agreement (a copy of which shall be provided for informational purposes only to Parent) with such Third Party with terms no less favorable to the Company than those contained in the Confidentiality Agreement; provided that such confidentiality agreement shall not prohibit compliance by the Company with any of the provisions of this Section 7.03; provided, further, that all such information (to the extent that such information has not been previously provided or made available to Parent) is provided or made available to Parent, as the case may be, prior to or substantially concurrently with the time it is provided or made available to such Third Party (or its Representatives); and

(ii) subject to compliance with the procedures set forth in this Section 7.03, the Board of Directors may make an Adverse Recommendation Change if the Board of Directors determines in good faith, after consultation with outside legal counsel and a financial advisor of nationally recognized reputation, that (A) a bona fide, unsolicited written Acquisition Proposal constitutes a Superior Proposal and that the failure to make such Adverse Recommendation Change violates its fiduciary duties under Applicable Law, or (B) in the absence of an Acquisition Proposal, if due to events or changes in circumstances after the date hereof that were neither known nor reasonably foreseeable by the Company as of or prior to the date hereof (such events or changes in circumstances, collectively, an “Intervening Event”), the failure to make an Adverse Recommendation Change violates its fiduciary duties under Applicable Law.

In addition, nothing contained herein shall prevent the Board of Directors from (i) complying with Rule 14e-2(a) under the 1934 Act with regard to an Acquisition Proposal so long as any action taken or statement made to so comply is consistent with this Section 7.03, or (ii) issuing a “stop, look and listen” disclosure or similar communication of the type contemplated by Rule 14d-9(f) under the 1934 Act.

(c) Required Notices. The Board of Directors shall not take any of the actions referred to in Section 7.03(b) or terminate this Agreement pursuant to Section 11.01(d)(i) unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action and, after taking such action, the Company shall continue to keep Parent reasonably informed of the status and terms of any discussions and negotiations with the applicable Third Party. In addition, the Company shall notify Parent promptly (but in no event later than 24 hours) after receipt by the Company (or any of its Representatives) of any Acquisition Proposal (including of the material terms and conditions thereof) or any request for information relating to the Company or for access to the business, properties, assets, books or records of the Company by any Third Party that may be considering making, or has made, an Acquisition Proposal. The

Company shall provide such notice orally and in writing and shall identify the Third Party making any such Acquisition Proposal or request. The Company shall keep Parent reasonably informed of the status and material details of any such Acquisition Proposal or request. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of the Company’s compliance with this Section 7.03(c) and Section 7.03(d).

(d) “Last Look”. (i) The Board of Directors shall not make an Adverse Recommendation Change pursuant to Section 7.03(b)(ii)(A) or terminate this Agreement pursuant to Section 11.01(d)(i) unless (A) such Acquisition Proposal constitutes a Superior Proposal, (B) the Company promptly notifies Parent, in writing at least five Business Days before taking that action, of its intention to do so, attaching the most current version of the draft agreement under which such Superior Proposal is proposed to be consummated and the identity of the Third Party making the Acquisition Proposal, and (C) Parent does not make, within five Business Days after its receipt of that written notification, an offer that renders such Superior Proposal no longer a Superior Proposal (provided that any amendment to the terms of such Superior Proposal shall require a new written notification from the Company and an additional five Business Day period under this Section 7.03(d)); and

(ii) The Board of Directors shall not make an Adverse Recommendation Change pursuant to Section 7.03(b)(ii)(B), unless, prior to taking such action, (A) the Board of Directors has given Parent at least five Business Days prior notice of its intention to make such Adverse Recommendation Change and a reasonable description of the Intervening Event that serves as the basis of such Adverse Recommendation Change, (B) at the end of such notice period, the Board of Directors shall have considered in good faith any revisions to the terms of this Agreement or any new transaction, agreement or structure proposed by Parent, and shall have determined in good faith, after consultation with its financial advisors and outside legal counsel, that failure to make an Adverse Recommendation Change would nevertheless still constitute a violation of its fiduciary duties under Applicable Law if such revisions or any new transaction, agreement or structure proposed were to be given effect, and (C) in the event of any change to the material facts and circumstances relating to such Intervening Event, the Company shall, in each case, have delivered to Parent an additional notice consistent with that described in clause (A) above of this Section 7.03(d)(ii) and an additional five Business Day notice period under clause (A) of this Section 7.03(d)(ii) shall commence, during which time the Company shall be required to comply with the requirements of this Section 7.03(d) anew with respect to such additional notice, including clauses (A) through (C) above of this Section 7.03(d)(ii).

(e) Definition of Superior Proposal. For purposes of this Agreement, “Superior Proposal” means a bona fide, unsolicited written Acquisition Proposal that is not subject to any due diligence condition and is for all of the outstanding Shares or all or substantially all of the consolidated assets of the Company on terms that the Board of Directors determines in good faith by a majority vote, after considering the advice of a financial advisor of nationally recognized reputation and outside legal counsel and taking into account all financial, legal, regulatory and other aspects of such Acquisition Proposal, including conditions contained therein and the Person making the Acquisition Proposal and any break-up fees, expense reimbursement provisions and conditions to consummation, are more favorable from a financial point of view to the Company’s stockholders than as provided hereunder (taking into account any proposal by Parent to amend the terms of this Agreement pursuant to Section 7.03(d)), which the Board of Directors determines is reasonably likely to be consummated and for which financing, if a cash transaction (whether or not in whole or in part), is then fully committed or reasonably determined to be available by the Board of Directors.

(f) Obligation of the Company to Terminate Existing Discussions. The Company shall, and shall cause its Representatives to cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any Third Party and its Representatives with respect to any Acquisition Proposal. The Company shall promptly request that each Third Party, if any, that has executed a confidentiality agreement within the 12-month period prior to the date hereof in connection with its consideration of any Acquisition Proposal return or destroy all confidential information heretofore furnished to such Person by or on behalf of the Company (and all analyses and other materials prepared by or on behalf of such Person that contains, reflects or analyzes that information), and the Company shall provide to Parent all certifications of such return or destruction from such other Persons as promptly as practicable after receipt thereof. The Company shall use its reasonable best efforts to secure all such certifications as promptly as practicable.

Section 7.04. Compensation Arrangements. As promptly as practicable after the date hereof, but in no event later than ten Business Days following the date of this Agreement, the Company (acting through its Compensation Committee of the Board of Directors (the “Compensation Committee”)) will take all steps necessary to cause each Employee Plan pursuant to which consideration is payable to any officer, director or employee to be approved by the Compensation Committee (comprised solely of “independent directors” determined in accordance with the requirements of Rule 14d-10(d)(2) under the 1934 Act and the instructions thereto) as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the 1934 Act and to satisfy the requirements of the non-exclusive safe harbor set forth in Rule 14d-10(d) of the 1934 Act.

Section 7.05. Financing Cooperation. Prior to the Effective Time, the Company shall use its reasonable best efforts to provide, and shall cause its

Affiliates and Representatives to use reasonable best efforts to provide, in connection with the arrangement of the Debt Financing, all reasonable cooperation requested by Parent that is customary in connection with the arrangement of debt financing for transactions that are substantially similar to the transactions contemplated by this Agreement, including using its reasonable best efforts to (a) furnish the Debt Providers in a timely manner with financial and other pertinent information regarding the Company required pursuant to the Debt Commitment Letter and necessary to commence the Required Marketing Period as defined in the Debt Commitment Letter (all such information, the “Required Information”) and any supplements to the Required Information required by the Debt Commitment Letters; (b) participate in a reasonable number of meetings, drafting sessions, road shows, rating agency presentations and due diligence sessions; (c) furnish Parent for distribution to the Debt Providers as promptly as practicable with pertinent information as is customary in connection with the Debt Financing regarding the Company’s assets and operations and any security required therefor, including providing, as promptly as practicable following a request therefor, monthly financial and operating data relating to the Company’s assets and operations that is reasonably requested by Parent; (d) assist Parent and the Debt Providers in the preparation of (i) a customary offering document for any of the Debt Financing, and (ii) materials for rating agency presentations; (e) use reasonable best efforts to obtain such UCC, bankruptcy, litigation and similar lien searches reasonably requested by Parent and consistent with the requirements of Parent or its lenders; (f) take all corporate actions, subject to the consummation of the Closing, reasonably requested by Parent to permit the consummation of the Debt Financing and to permit the proceeds thereof to be made available to Parent; (g) cause the appropriate authorized Representatives of the Company to execute and deliver any pledge and security documents, definitive financing documents or other certificates or documents as may be reasonably requested by Parent or otherwise facilitate the pledging of Collateral (as defined in the Debt Commitment Letter) for delivery at the consummation of the Financing at and as of the Effective Time (unless otherwise specified, but not before the Effective Time); (h) cause the appropriate authorized Representatives of the Company to execute and deliver any credit agreements or indentures or other definitive financing documents on terms satisfactory to Parent at and as of the Effective Time; (i) provide, if requested by Parent, authorization letters to the Debt Providers authorizing the distribution of information to prospective lenders; (j) cooperate reasonably with the Debt Providers’ due diligence, to the extent customary and reasonable; (k) cooperate reasonably with the Debt Providers to obtain accountant’s comfort letters, which comfort letter shall comply with the requirements of PCAOB AU Section 634, and legal opinions reasonably requested by Parent and customary for financings similar to the Debt Financing; (l) at least five (5) days prior to the Effective Time, provide all documentation and other information about the Company as is reasonably requested in writing by Parent which relates to applicable “know your customer” and anti-money laundering rules and regulations including without limitation the USA PATRIOT ACT; and (m) take all actions reasonably necessary to permit the Debt Providers

to evaluate the Company’s inventory, current assets, cash management and accounting systems, policies and procedures relating thereto. Nothing in this Section 7.05 shall require such cooperation to the extent it would (i) require the Company to waive or amend any terms of this Agreement, (ii) unreasonably interfere with the ongoing operations of the Company, or (iii) reasonably be expected to result in a violation of Applicable Law or loss of attorney-client privilege. No liability or obligation of the Company or its Affiliates or Representatives, under any certificate, agreement, arrangement, document or instrument relating to the Debt Financing shall be effective until the Effective Time. Parent shall indemnify and hold harmless the Company and its Affiliates and their respective Representatives from and against any and all losses, damages, claims, costs or expenses suffered or incurred by any of them in connection with the arrangement of the Debt Financing and any information used in connection therewith, in each case other than to the extent any of the foregoing arises from the bad faith, gross negligence or willful misconduct of, or material breach of this Agreement by, the Company or any of its Affiliates. Any information provided by the Company in connection with seeking the Debt Financing shall be prepared in good faith. Parent shall reimburse the Company for all of its documented reasonable out-of-pocket costs and expenses in connection with this Section 7.05 on or prior to the Effective Time or promptly following the Effective Time or the termination of this Agreement.

Section 7.06. Section 16 Matters. Prior to the Effective Time, the Company shall take all such steps as may be required to cause any dispositions of Shares in connection with the Merger (including Company Stock Options and Company RSUs) by each individual who is subject to the reporting requirements of Section 16(a) of the 1934 Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the 1934 Act.

ARTICLE 8

Covenants of Parent

Parent agrees that:

Section 8.01. Obligations of Merger Subsidiary. Parent shall take all action necessary to cause Merger Subsidiary to perform its obligations under this Agreement and to consummate the Offer and the Merger on the terms and conditions set forth in this Agreement.

Section 8.02. Director and Officer Liability. Parent shall cause the Surviving Corporation, and the Surviving Corporation hereby agrees, to do the following:

(a) For six years after the Effective Time, the Surviving Corporation shall indemnify and hold harmless the present and former officers and directors of the Company (each, an “Indemnified Person”) in respect of acts or omissions in

their capacity as officers or directors, as applicable, of the Company occurring at or prior to the Effective Time to the fullest extent permitted by Delaware Law and any other Applicable Law and permitted under the Company’s certificate of incorporation and bylaws in effect on the date hereof; provided that such indemnification shall be subject to any limitation imposed from time to time under Applicable Law.

(b) For six years after the Effective Time, Parent shall cause to be maintained in effect provisions in the Surviving Corporation’s certificate of incorporation and bylaws (or in such documents of any successor to the business of the Surviving Corporation) regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in existence on the date of this Agreement.

(c) Prior to the Effective Time, the Company shall or, if the Company is unable to, Parent shall cause the Surviving Corporation as of the Effective Time to, obtain and fully pay the premium for the non-cancellable extension of the directors’ and officers’ liability coverage of the Company’s existing directors’ and officers’ insurance policies and the Company’s existing fiduciary liability insurance policies (collectively, “D&O Insurance”), in each case for a claims reporting or discovery period of at least six years from and after the Effective Time with respect to any claim related to any period or time at or prior to the Effective Time with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company’s existing policies; provided, however, that the Company shall give Parent a reasonable opportunity to participate in the selection of such tail policy and the Company shall give reasonable and good faith consideration to any comments made by Parent. If the Company or the Surviving Corporation for any reason fail to obtain such “tail” insurance policies as of the Effective Time, the Surviving Corporation shall continue to maintain in effect, for a period of at least six years from and after the Effective Time, the D&O Insurance in place as of the date hereof, or the Surviving Corporation shall purchase comparable D&O Insurance for such six-year period with terms, conditions, retentions and limits of liability that are no less favorable than as provided in the Company’s existing policies as of the date hereof; provided that in no event shall Parent or the Surviving Corporation be required to expend for such policies pursuant to this sentence an annual premium amount in excess of 225% of the amount per annum the Company paid in its last full fiscal year, which amount is set forth in Section 8.02(c) of the Company Disclosure Schedule.

(d) If Parent, the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, 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 8.02.

(e) The rights of each Indemnified Person under this Section 8.02 shall be in addition to any rights such Person may have under the certificate of incorporation or bylaws of the Company, under Delaware Law or any other Applicable Law or under any agreement of any Indemnified Person with the Company. These rights shall survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Person.

Section 8.03. Employee Matters. (a) For a period of no less than twelve (12) months following the Effective Time, Parent shall provide or cause to be provided to all employees of the Company as of the Effective Time who continue employment with Parent or any of its Affiliates (“Continuing Employees”) (i) compensation and benefits that are in the aggregate substantially comparable to the compensation and benefits provided by the Company to the Continuing Employees as in effect immediately prior to the Effective Time, and (ii) severance benefits that are no less favorable than the severance benefits set forth on Section 8.03(a) of the Company Disclosure Schedule which Continuing Employees would have received from the Company upon a termination of employment immediately prior to the Effective Time.

(b) Except as would result in a duplication of benefits, with respect to any employee benefit plan maintained by Parent or any of its Affiliates in which any Continuing Employee becomes a participant (excluding any equity compensation or benefit accrued under a defined benefit plan), such Continuing Employee shall receive full credit for service with the Company (or predecessor employers to the extent the Company provides such past service credit) to the same extent that such service was recognized as of the Effective Time under a comparable plan of the Company in which the Continuing Employee participated.

(c) With respect to any welfare plan maintained by Parent or any of its Affiliates in which any Continuing Employee is eligible to participate after the Effective Time, Parent shall, or shall cause its Affiliates to, (i) waive all limitations as to preexisting conditions and exclusions with respect to participation and coverage requirements applicable to such employees to the extent such conditions and exclusions were satisfied or did not apply to such employees under the welfare plans of the Company prior to the Effective Time, and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid and for out-of-pocket maximums incurred prior to the Effective Time in satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan.

(d) Nothing in this Section 8.03 shall (i) be treated or construed as an amendment of, or undertaking to amend, any employee benefit plan, (ii) prohibit Parent, the Company or any of Parent’s Subsidiaries from amending or terminating any employee benefit plan, (iii) obligate Parent, the Company or any

of Parent’s Subsidiaries to retain the employment of any particular employee, or (iv) confer any rights or benefits on any Person other than the parties to this Agreement.

Section 8.04. Financing. Parent shall use its commercially reasonable efforts to (a) arrange the Financing on the terms and conditions described in the Financing Commitment Letters, (b) enter into definitive agreements with respect thereto (that are customary for financings of this type) on the terms and conditions contained in the Financing Commitment Letters, which agreements shall be in effect as promptly as practicable after the date hereof, but in no event later than the Effective Time, and (c) consummate the Financing no later than the Effective Time in accordance with the terms contained in the Financing Commitment Letters; provided that Parent may agree to or permit any amendment, modification or waiver of the Financing Commitment Letters that would not, or would not reasonably be expected to, (i) materially adversely impact (A) the ability of Parent to timely consummate the transactions contemplated by this Agreement or (B) the likelihood of consummation of the transaction contemplated by this Agreement or (ii) expand upon the conditions precedent to the Debt Financing as set forth in the Debt Commitment Letters; provided, further, that Parent shall promptly deliver to the Company copies of any such amendment, modification or waiver following the execution of the same. In the event that any portion of the Financing becomes unavailable in the manner or from the sources contemplated in the Financing Commitment Letters, (1) Parent shall promptly notify the Company and (2) Parent shall use its commercially reasonable efforts to arrange to obtain any such portion from alternative sources (“Alternative Debt Financing”), on terms that are not materially less favorable from the standpoint of Parent and Merger Subsidiary than the terms and conditions set forth in the Financing Commitment Letters, as promptly as practicable following the occurrence of such event, including entering into definitive agreements with respect thereto (such definitive agreements entered into pursuant to the first or second sentence of this Section 8.04 being referred to as the “Financing Agreements”). Parent and Merger Subsidiary shall, and shall cause their respective Representatives to, use commercially reasonable efforts to comply with the terms, and satisfy on a timely basis the conditions, in each case those that are within their control, of the Financing Commitment Letters, any Alternative Debt Financing, the Financing Agreements and any related fee and engagement letters. Parent shall keep the Company reasonably informed of the status of its efforts to arrange the Financing (or any replacement thereof). Parent shall give the Company prompt written notice, in any event within forty-eight (48) hours of Parent’s knowledge, of any actual breach, default, expiration, termination or repudiation of any Debt Financing Commitment by any party thereto of which Parent becomes aware.

ARTICLE 9

Covenants of Parent and the Company

The parties hereto agree that:

Section 9.01. Approval of the Merger. (a) Merger Effectiveness. Subject to the terms and conditions contained herein and notwithstanding anything to the contrary contained herein, the Company, Parent and Merger Subsidiary agree to take all necessary and appropriate action to cause the Merger to become effective as promptly as practicable in accordance with Delaware Law.

(b) Proxy Material. The Company shall, as promptly as reasonably practicable (and in any event within ten Business Days) after the date hereof, prepare and file with the SEC in preliminary form, and shall thereafter use its reasonable best efforts to have cleared by the SEC, the Company Proxy Statement that will be provided to the Company’s stockholders in connection with the solicitation of proxies for use at the meeting of the Company’s stockholders called to vote upon the adoption of this Agreement and the approval of Merger (the “Company Stockholder Meeting”).

(c) Company Proxy Statement. The Company shall afford Parent and its counsel a reasonable opportunity to review and comment on the Company Proxy Statement prior to its filing with the SEC, including any amendments or supplements thereto, and shall give due consideration to all the reasonable additions, deletions or changes suggested thereto by Parent.

The Company shall, as promptly as practicable, provide responses to the SEC with respect to all comments received on the Company Proxy Statement from the SEC. To the extent required by Applicable Law in good faith judgment of the Company, the Company shall, as promptly as reasonably practicable, prepare, file and distribute to its stockholders any supplement or amendment to the Company Proxy Statement, if any event shall occur that requires such action.

(d) Company Stockholder Meeting. If adoption of this Agreement by the Company’s stockholders is required by Applicable Law and the Offer has been terminated pursuant to Section 2.01(e), the Company shall, as promptly as reasonably practicable (and in any event within ten Business Days) after the Proxy Statement Clearance Date, (i) take all action necessary in accordance with Applicable Law, Nasdaq rules, the Company’s certificate of incorporation and the Company’s bylaws to establish a record date for and give notice of the Company Stockholder Meeting, and (ii) mail to the holders of Shares as of the record date the Company Proxy Statement.

Any adjournment or postponement of the Company

Stockholder Meeting shall require the prior written consent of Parent, except that (A) the Company may adjourn the Company Stockholder Meeting in the case and then only to the extent that such adjournment is required to allow additional time for the filing and mailing of any supplemental or amended disclosure which the SEC has instructed the Company is necessary under Applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the Company’s stockholders prior to the Company Stockholder Meeting, and (B) the Company, after consultation with Parent, may (and, upon the written request of Parent, shall) adjourn or postpone the Company Stockholder Meeting if as of the time for which the Company Stockholder Meeting is originally scheduled (as set forth in the Company Proxy Statement) there are either (1) insufficient Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct business at the Company Stockholder Meeting or (2) insufficient affirmative votes to adopt this Agreement and approve the Merger; provided, that the record date shall not be changed without Parent’s consent, except as required by Applicable Law or by the certificate of incorporation or bylaws of the Company in effect as of the date hereof. Without the prior written consent of Parent, the adoption of this Agreement and the approval of the Merger and the transactions contemplated thereby shall be the only matter (other than (x) procedural matters and (y) an advisory vote with respect to golden parachute compensation arrangements in accordance with applicable federal securities laws) which the Company shall propose to be acted on at the Company Stockholder Meeting. The Company shall, upon the request of Parent, advise Parent at least on a daily basis on each of the last seven Business Days prior to the scheduled date of the Company Stockholder Meeting as to the aggregate tally of affirmative proxies received by the Company.

Section 9.02. Regulatory Undertakings. (a) Subject to the terms and conditions of this Agreement, the Company and Parent shall use their reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done,

The Company and Parent shall use their reasonable best efforts to cooperate with one another (a) in connection with the preparation of the Company Disclosure Documents and the Offer Documents, (b) in determining whether any action by or in respect of, or filing with, any Governmental Authority is required, or any actions, consents, approvals or waivers are required to be obtained from parties to any Material Contracts, in connection with the consummation of the transactions contemplated by this Agreement, and (c) in taking such actions or making any such filings, furnishing information required in connection therewith or with the Company Disclosure Documents or the Offer Documents and seeking timely to obtain any such actions, consents, approvals or waivers.

Section 9.04. Public Announcements. The initial press release with respect to this Agreement and the transactions contemplated hereby shall be a joint press release, to be agreed upon by Parent and the Company. Parent and the Company shall consult with each other and provide the other party a reasonable opportunity to review and comment before issuing any press release, having any communication with the press (whether or not for attribution) or making any other public statement, or scheduling any press conference or conference call with investors or analysts, with respect to this Agreement or the transactions contemplated hereby and, except in respect of any public statement or press release as may be required by Applicable Law or any listing agreement with or

rule of any national securities exchange or association, shall not issue any such press release or make any such other public statement or schedule any such press conference or conference call before such consultation; provided, however, that each party may make an oral or written press release, communication, or public statement without complying with the foregoing procedures if the substance of such press release, communication, or public statement was publicly disclosed and previously subject to the foregoing requirements.

At and after the Effective Time, the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Company or Merger Subsidiary, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company or Merger Subsidiary, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets of the Company acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

(d) any inaccuracy of any representation or warranty contained in this Agreement at any time during the term hereof that could reasonably be expected to cause any Offer Condition not to be satisfied; and

(e) any failure of that party, or any Representative thereof, to comply with or satisfy any covenant, condition or agreement in this Agreement that could reasonably be expected to cause any Offer Condition or any of the conditions set forth in Article 10 not to be satisfied.

In addition, the Company shall notify Parent promptly of any change or event having, or which is reasonably expected to have, a Company Material Adverse Effect or which would reasonably be expected to result in the failure of any Offer Condition to be satisfied. In no event shall the delivery of any notice

Section 12.03. Amendments and Waivers. (a) Any provision of this Agreement may be amended or waived prior to the Effective Time if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or, in the case of a waiver, by each party against whom the waiver is to be effective; provided that (i) after the Offer Closing, no amendment shall be made without the approval of a majority of the Independent Directors, and (ii)after the Company Stockholder Approval has been obtained, there shall be no amendment or waiver that would require the further approval of the stockholders of the Company under Delaware Law without such approval having first been obtained.

(b) No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law.

Section 12.04. Fees and Expenses. (a) General. Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.

(b) Termination Fee.

(i) If this Agreement is terminated by Parent pursuant to Section 11.01(c)(i) or Section 11.01(c)(iii) or by the Company pursuant to

Section 11.01(d)(i), then the Company shall pay to Parent as liquidated damages and not as a penalty by wire transfer in immediately available funds $5,000,000 (the “Termination Fee”), in the case of a termination by Parent, within one Business Day after such termination and, in the case of a termination by the Company, immediately before and as a condition to such termination.

(ii) If (A) this Agreement is terminated by Parent or the Company pursuant to Section 11.01(b)(i) or Section 11.01(b)(iii) or by Parent pursuant to Section 11.01(c)(ii), (B) after the date of this Agreement and prior to such termination an Acquisition Proposal shall have been publicly announced or otherwise been communicated to the Company’s stockholders and not withdrawn prior to such termination, and (C) within 12 months following the date of such termination, the Company shall have entered into a definitive agreement with respect to or recommended to its stockholders an Acquisition Proposal or an Acquisition Proposal shall have been consummated (provided that for purposes of this clause (C), each reference to “10%” in the definition of Acquisition Proposal shall be deemed to be a reference to “50%”), then the Company shall pay to Parent in immediately available funds, concurrently with the occurrence of the applicable event described in clause (C), the Termination Fee, less any Parent Expenses previously paid by the Company to Parent.

(iii) If this Agreement is terminated by Parent or the Company pursuant to Section 11.01(b)(iii) or by Parent pursuant to Section 11.01(c)(ii), then the Company shall pay to Parent by wire transfer in immediately available funds within one Business Day after such termination, the reasonable and documented out-of-pocket expenses incurred by Parent and Merger Subsidiary in connection with this Agreement and the transactions contemplated by this Agreement (including the Financing) in an amount not to exceed $2,000,000 (the “Parent Expenses”).

(iv) If this Agreement is terminated by the Company pursuant to Section 11.01(d)(ii), Section 11.01(d)(iii) or Section 11.01(d)(iv), Parent shall promptly pay (but in no event later than one Business Day after the date of such termination) to the Company as liquidated damages and not as a penalty by wire transfer in immediately available funds, $10,000,000 in cash (the “Parent Termination Fee”).

Each of the Company, Parent and Merger Subsidiary acknowledges that the agreements contained in this Section 12.04 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the Company, Parent and Merger Subsidiary would not enter into this Agreement. Accordingly, if the Company fails promptly to pay the Termination Fee or Parent Expenses when due or Parent shall fail to

pay the Parent Termination Fee when due, the Company or Parent, as the case may be, shall also pay any costs and expenses incurred by the other party in connection with a legal action to enforce this Agreement that results in a judgment against the party who has failed to make such payments when due for such amount, together with interest on the amount of any unpaid fee, cost or expense at the publicly announced prime rate of Citibank, N.A. from the date such fee, cost or expense was required to be paid to (but excluding) the payment date.

(d) Exclusive Remedies. Each of the parties hereto further acknowledges that neither the payment of the amounts by the Company nor the payment of the amounts by Parent specified in this Section 12.04 is a penalty, but in each case is liquidated damages in a reasonable amount that will compensate Parent and Merger Subsidiary or the Company, as the case may be, in the circumstances in which such fees are payable. Notwithstanding anything to the contrary in this Agreement, the parties agree that (i)(A) the Company’s right to terminate this Agreement and to receive the Parent Termination Fee pursuant to this Section 12.04 and any costs and expenses pursuant to Section 12.04(b) and (B) the specific performance remedies set forth in Section 12.13 shall be the sole and exclusive remedies of the Company and its Affiliates against Parent, Merger Subsidiary, Financing Source and any of their respective former, current or future general or limited partners, stockholders, managers, members, Affiliates or Representatives (each a “Parent Related Party”) for any loss suffered as a result of any breach of any representation, warranty, covenant or agreement or the failure of the transactions contemplated hereunder to be consummated, and upon payment of such amount, none of Parent or Merger Subsidiary or any other Parent Related Party shall have any further liability or obligation relating to or arising out of this Agreement, an agreement executed in connection herewith (including the Equity Commitment Letter, the Limited Guarantee and the Debt Commitment Letter) or the transactions contemplated hereby and thereby; and (ii)(A) Parent’s right to terminate this Agreement and to receive the Termination Fee and the Parent Expenses, where applicable, pursuant to this Section 12.04 and any costs and expenses pursuant to Section 12.04(b) and (B) the specific performance remedies set forth in Section 12.13 shall be the sole and exclusive remedies of Parent and Merger Subsidiary against the Company and any of its Subsidiaries former, current or future stockholders, managers, members, Affiliates or Representatives (each a “Company Related Party”) for any loss suffered as a result of any breach of any representation, warranty, covenant or agreement or the failure of the transactions contemplated hereunder to be consummated, and upon payment of such amount, none of the Company or any other Company Related Party shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby. In no event shall Parent be entitled to receive more than one payment of the Termination Fee or Parent Expenses. In no event shall the Company be entitled to receive more than one payment of the Parent Termination Fee. The parties acknowledge and agree that the foregoing is intended to mean that no party or its Affiliates can seek damages from the Company or any other Company Related Party on one the hand, or from Parent, Merger Subsidiary or any other Parent Related Party on the other hand,

except upon termination of this Agreement and pursuant to the liquidated damages provisions described in this Section 12.04 or pursuant to Section 11.02(b).

The mere inclusion of an item in either the Company Disclosure Schedule or the Parent Disclosure Schedule as an exception to a representation or warranty (or covenant, as applicable) shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has had or would reasonably be expected to have a Company Material Adverse Effect or Parent Material Adverse Effect, as applicable.

(b) The parties hereto agree that any information contained in any part of any Company SEC Document shall only be deemed to be an exception to (or a disclosure for purposes of) the Company’s representations and warranties if the relevance of that information as an exception to (or a disclosure for purposes of) such representations and warranties would be reasonably apparent to a person who has read that information concurrently with such representations and warranties, without any independent knowledge on the part of the reader regarding the matter(s) so disclosed.

Section 12.06. Binding Effect; Benefit; Assignment. (a) The provisions of this Agreement shall be binding upon and, except as provided in Section 8.02, shall inure to the benefit of the parties hereto and their respective successors and assigns. Except as provided in Section 8.02, Section 12.04 and this Section 12.06, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto

and their respective successors and assigns; provided, however, that the Financing Sources and their respective current, former or future general or limited partners, stockholders, members, managers, controlling persons, Affiliates or Representatives shall be third party beneficiaries of Section 11.02, Section 12.04, this Section 12.06, Section 12.07, Section 12.08, Section 12.09 and Section 12.14 (which may not be changed as to any Financing Source without its prior written consent).

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto, except that Parent or Merger Subsidiary may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to one or more of its Affiliates at any time and, after the Acceptance Time, to the Offer to any Person; provided that such transfer or assignment shall not relieve Parent or Merger Subsidiary of its obligations under the Offer, enlarge, alter or change any obligation of any other party hereto or due to Parent or Merger Subsidiary or prejudice the rights of tendering stockholders to receive payment for Shares validly tendered and accepted for payment pursuant to the Offer.

Section 12.07. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of Delaware.

Section 12.08. Jurisdiction. The parties hereto agree that any suit, action or Proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby (whether brought by any party or any of its Affiliates or against any party or any of its Affiliates) shall be brought in the Delaware Chancery Court or, if such court shall not have jurisdiction, any federal court located in the State of Delaware or other Delaware state court, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such Proceeding in any such court or that any such Proceeding brought in any such court has been brought in an inconvenient forum. Process in any such Proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 12.01 (except for notice by e-mail) shall be deemed effective service of process on such party. Without in any way limiting any waiver of Financing Source liability or any other provision relating to the Financing Sources and notwithstanding anything to the contrary in this Agreement, no party hereto, nor any of its Affiliates or Representatives, will bring, or support the bringing of, any claim, whether at law or in equity, whether in contract or in tort or otherwise, against any Financing Source in any way relating to this Agreement or any of the

transactions contemplated by this Agreement, including any dispute arising out of relating in any way to the Financing Commitment Letters or the performance thereof, anywhere other than in the Supreme Court of the State of New York, County of New York, or, if under Applicable Law exclusive jurisdiction is vested in the federal courts, the United States District Court for the Southern District of New York (and the appellate courts thereof) and the laws of New York shall govern any such action. The parties also hereby agree (a) that a final judgment in any such action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law and (b) to irrevocably waive and hereby waive any right to a trial by jury in any such action to the same extent such rights are waived pursuant to Section 12.09.

Section 12.09. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication). Delivery of an executed signature page of this Agreement by facsimile or other customary means of electronic transmission (e.g., “pdf”) shall be effective as delivery of a manually executed counterpart hereof.

Section 12.11. Entire Agreement.

Section 12.12. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 12.13. Specific Performance. The parties to this Agreement agree that irreparable damage would occur if 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 to this Agreement shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the courts contemplated by Section 12.08, this being in addition to any other remedy at law or in equity, and the parties to this Agreement hereby waive any requirement for the posting of any bond or similar collateral in connection therewith. Notwithstanding anything in this Agreement to the contrary, prior to the Acceptance Time, the Company shall be entitled to specific performance to cause Parent and Merger Subsidiary to draw down the Equity Financing pursuant to the terms and conditions of the Equity Commitment Letter, and to consummate the Offer and the Merger, only if (a) with respect to the Offer, all of the Offer Conditions have been satisfied or waived (other than those conditions that, by their nature, are to be satisfied at the expiration of the Offer (and which are, at the time that the Company seeks specific performance pursuant to this Section 12.13, capable of being satisfied if the Acceptance Time were to occur at such time)), (b) with respect to the Merger, all of the conditions set forth in Sections 10.01 and 10.02 shall have been satisfied or waived as of the time when the Closing would have occurred pursuant to Section 3.01 but for the failure of the Equity Financing to be funded, (c) the Debt Financing has been funded or will be funded at or promptly after the Offer Closing or at or prior to the Closing, as applicable, upon delivery of a drawdown notice by Parent and/or notice from Parent that the Equity Financing will be funded at such date, (d) Parent and Merger Subsidiary fail to consummate the Offer or effect the Closing in accordance with Section 2.01 or Section 3.01, respectively, and (e) with respect to the Merger, the Company has irrevocably confirmed that if specific performance is granted and the Equity Financing and Debt Financing are funded, then the Closing will occur. For the avoidance of doubt, in no event shall the Company be entitled to enforce or seek to enforce specifically Parent’s obligation to cause the Equity Financing to be funded or to consummate the Offer or the Merger if the Debt Financing has not been funded (or will not be funded at or promptly after the Acceptance Time or at or prior to the Closing, as applicable, if the Equity Financing is funded at such time). Under no circumstances shall the Company be permitted or entitled to receive both a grant of specific performance causing Parent and/or Merger Subsidiary to accept for payment all Shares validly tendered and not validly withdrawn pursuant to the Offer pursuant to this Section 12.13 and the payment of all or any portion of the Parent Termination Fee.

Section 12.14. Certain Agreements with Respect to Debt Providers. The Company agrees, on behalf of itself and the Company Related Parties that the Debt Providers, each other lender participating in the Debt Financing or any Alternative Debt Financing and each of their respective former, current or future general or limited partners, stockholders, managers, members, Representatives and Affiliates and each of their successors and assigns (collectively, “Debt Related Parties”) shall be subject to no liability or claims, whether for any claims

at law, in equity, in contract, in tort or otherwise, by the Company Related Parties arising out of or relating to this Agreement, the Debt Financing or the transactions contemplated hereby or in connection with the Debt Financing, or the performance of services by such Debt Related Parties. Notwithstanding anything to the contrary in this Agreement, including Section 12.03, (a) no amendment or modification to this Section 12.14 (or amendment or modification with respect to any related definitions as they affect this Section 12.14) shall be effective without the prior written consent of the Debt Providers and (b) each Debt Related Party shall be an express third party beneficiary of, and shall have the right to enforce, this Section 12.14.

(a) the Minimum Tender Condition shall not have been satisfied;

(b) the HSR Act Condition shall not have been satisfied;

(c) the Company shall have failed to deliver to Parent a certificate signed by an executive officer of the Company dated as of the date on which the Offer expires certifying that the Offer Conditions specified in (e) or (f) of this Annex I do not exist;

(d) there is a law, rule or Order of any Governmental Authority with competent jurisdiction directly or indirectly restraining, prohibiting, delaying or otherwise making illegal the Offer, the acceptance for payment of or payment for some or all of the Shares by Parent or Merger Subsidiary, or the Merger;

(e) (1) any of the representations and warranties of the Company contained in the first, second or fourth sentence of Section 5.05(a) or the first or second sentence of Section 5.05(b) shall not be true (other than such inaccuracies as are de minimis to (i) the equity capitalization of the Company in the aggregate or (ii) the aggregate purchase price to be paid hereunder) at and as of immediately prior to the expiration of the Offer as if made at and as of such time; (2) any of the representations and warranties of the Company contained in any of Section 5.01, Section 5.02, Section 5.20 or Section 5.21 shall not be true at and as of immediately prior to the expiration of the Offer as if made at and as of such time (other than any such representation and warranty that by its terms addresses matters only as of another specified time, which shall be true only as of such time); or (3) any of the other representations and warranties of the Company contained in this Agreement or in any certificate or other writing delivered by the Company pursuant hereto (disregarding all materiality and Company Material Adverse Effect qualifications contained therein except as set forth on Section I of the Company Disclosure Schedule) shall not be true at and as of immediately prior to the expiration of the Offer as if made at and as of such time (other than any such representation and warranty that by its terms addresses matters only as of another specified time, which shall be true only as of such time), except, in the case of this clause (3) only, where the failure of such representations and warranties to be so

(f) the Company shall have breached or failed to perform or comply in any material respect with any of its obligations, agreements or covenants under this Agreement prior to such time;

(g) there shall have occurred any general suspension of trading in, or limitation on prices for, securities on the New York Stock Exchange or in the over-the-counter market, any declaration of a banking moratorium by federal or New York authorities or general suspension of payments in respect of lenders that regularly participate in the U.S. market in loans to large corporations, any material limitation by any Governmental Authority in the United States that materially affects the extension of credit generally by lenders that regularly participate in the U.S. market in loans to large corporations, any commencement of a war involving the United States or any commencement of armed hostilities or other national or international calamity involving the United States that has a material adverse effect on bank syndication or financial markets in the United States or, in the case of any of the foregoing occurrences existing on or at the time of the commencement of the Offer, a material acceleration or worsening thereof;

(h) there shall have occurred any event, change, occurrence or development which, individually or in the aggregate, has had or would reasonably be expected to have a Company Material Adverse Effect;

(i) in the event that the exercise of the Top-Up Option is necessary to ensure that Merger Subsidiary owns at least one Share more than the number of Shares necessary for Merger Subsidiary to be merged into the Company without a vote or consent of the Company’s stockholders in accordance with Section 253 of Delaware Law immediately after the Acceptance Time, (1) there shall exist under Applicable Law or other restraint any restriction or legal impediment on (i) Merger Subsidiary’s ability and right to exercise the Top-Up Option, or (ii) the Company’s ability to issue the Top-Up Shares to Merger Subsidiary, or (2) the number of Shares issuable upon the exercise of the Top-Up Option, when added to the number of Shares owned by Merger Subsidiary, together with the Contributed Shares, at the time of such exercise, shall be insufficient for Merger Subsidiary to be merged into the Company without a vote or consent of the Company’s stockholders in accordance with Section 253 of Delaware Law (a “Top-Up Impediment”); or

(j) this Agreement shall have been terminated in accordance with its terms.

The failure by Parent or Merger Subsidiary at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.
