Section 2.02. Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Subsidiary, the Company or the holders of any shares of Company Common Stock or any shares of capital stock of Parent or Merger Subsidiary:

(a) except as otherwise provided in Section 2.02(b) or Section 2.04, each share of Company Common Stock outstanding immediately prior to the Effective Time shall be converted into the right to receive $11.00 in cash, without interest (such per share amount, the “Merger Consideration”). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each certificate which immediately prior to the Effective Time represented any such shares of Company Common Stock (each, a “Certificate”) and each uncertificated share of Company Common Stock (each, an “Uncertificated Share”) which immediately prior to the Effective Time was registered to a holder on the stock transfer books of the Company, shall thereafter represent only the right to receive the Merger Consideration;

(b) each share of Company Common Stock held by the Company or owned by Parent or any of its Subsidiaries immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto; and

(c) each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one share of common stock of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(a) Prior to the Effective Time, Parent shall appoint a commercial bank or trust company that is reasonably satisfactory to the Company (the “Paying Agent”) to act as paying agent for the purpose of paying the Merger Consideration to the holders of Company Common Stock and shall enter into a paying agent agreement with the Paying Agent. At or prior to the Effective Time, Parent shall deposit, or cause to be deposited, with the Paying Agent, for the

benefit (from and after the Effective Time) of the holders of shares of Company Common Stock, for payment in accordance with this Section 2.03 through the Paying Agent, cash sufficient to pay the aggregate Merger Consideration pursuant to Section 2.02. All cash deposited with the Paying Agent pursuant to this Section 2.03(a) shall be referred to as the “Payment Fund.” Promptly after the Effective Time (and in any event within two (2) Business Days following the Closing Date), Parent shall send, or shall cause the Paying Agent to send, to each Person who was, immediately prior to the Effective Time, a holder of record of shares of Company Common Stock entitled to receive payment of the Merger Consideration pursuant to Section 2.02(a) 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 in accordance with the procedures set forth in the letter of transmittal) for use in such payment. The Payment Fund may be invested by the Paying Agent as directed by Parent in short term obligations of the United States of America with maturities of no more than thirty (30) days, short term obligations guaranteed by the United States of America, commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of investment. Any interest or income produced by such investments will be payable to the Surviving Corporation or Parent, as Parent directs.

(b) Each holder of shares of Company Common Stock that have been converted into the right to receive the Merger Consideration pursuant to Section 2.02 shall be entitled to receive, upon (i) surrender to the Paying Agent of a Certificate, together with a properly completed and validly executed 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 in respect of the Company Common Stock represented by a Certificate or 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) The stock transfer books of the Company shall be closed immediately upon the Effective Time and there shall be no further registration of transfers of shares of Company Common Stock thereafter on the records of the Company. If, after the Effective Time, Certificates or Uncertificated Shares are presented to Parent, the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and converted into the right to receive only the Merger Consideration to the extent provided for, and in accordance with the procedures set forth, in this Article 2.

(e) Any portion of the Merger Consideration made available to the Paying Agent pursuant to Section 2.03(a) that remains unclaimed by the holders of shares of Company Common Stock six (6) months after the Effective Time shall be delivered to Parent or otherwise on the instruction of Parent, and any such holder who has not exchanged shares of Company Common Stock for the Merger Consideration in accordance with this Section 2.03 prior to that time shall thereafter look only to Parent for payment of the Merger Consideration, in respect of such shares without any interest thereon. Notwithstanding the foregoing, Parent shall not be liable to any holder of shares of Company Common Stock for any amounts paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of shares of Company Common Stock 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 interest of any Person previously entitled thereto.

Section 2.04. Dissenting Shares. Notwithstanding any provision in this Agreement to the contrary, shares of Company Common Stock outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has properly demanded that the Company purchase such shares in accordance with Chapter 13 of California Law (collectively, the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration. Holders of Dissenting Shares shall be entitled only to such rights as are granted by Chapter 13 of California Law. If, after the Effective Time, such holder fails to perfect, withdraws or loses the right to dissent under Chapter 13 of California Law, 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 payment of any shares of Company Common Stock pursuant to Chapter 13 of California Law, 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.

(a) Options. At the Effective Time, each outstanding Company Stock Option, whether or not then exercisable or vested, shall become fully vested and be cancelled in exchange for the right to receive, as soon as reasonably practicable after the Effective Time (but in any event no later than three (3) Business Days after the Effective Time), an amount in cash equal to the product of (A) the total number of shares of Company Common Stock subject to such Company Stock Option immediately prior to the Effective Time, multiplied by (B) the excess, if any, of the Merger Consideration over the exercise price per share of Company Common Stock under such Company Stock Option, less any applicable taxes required to be withheld with respect to such payment. As used herein, the term “Company Stock Option” shall mean any outstanding option under the Stock Plans to purchase shares of capital stock of the Company. As of the Effective Time, each Company Stock Option for which the exercise price per share of Company Common Stock equals or exceeds the Merger Consideration shall be canceled and have no further effect, with no right to receive any consideration therefor. As of the Effective Time, all other Company Stock Options shall no longer be outstanding and shall automatically cease to exist and shall become only the right to receive the option consideration

described in this Section 2.05(a), and, without limiting the foregoing, the Board of Directors of the Company or the appropriate committee thereof shall take all reasonable actions to effectuate the terms of this Section 2.05(a), including obtaining any required participant consent.

(b) Employee Stock Purchase Plan. As soon as practicable following the date of this Agreement, the Board of Directors of the Company or the compensation committee of the Board of Directors of the Company will adopt such resolutions and take such other reasonable actions as may be required to provide that with respect to the Company’s Employee Stock Purchase Plan (the “ESPP”): (A) participants in the ESPP may not alter their payroll deductions from those in effect on the date of this Agreement (other than to discontinue their participation in the ESPP), (B) no offering period will be commenced after the date of this Agreement, (C) any offering period under the ESPP that is in effect as of the date of this Agreement shall terminate on the twentieth (20th) Business Day following the date of this Agreement and all amounts credited to the accounts of participants shall be used to purchase shares of Company Common Stock in accordance with the terms of the ESPP (and such shares shall be treated as other outstanding shares in accordance with Section 2.02 of this Agreement); and (D) the ESPP shall be terminated, effective as of the Effective Time.

(c) Company Restricted Stock Units. At the Effective Time, each outstanding Company Restricted Stock Unit shall become fully vested and be cancelled in exchange for the right to receive, as soon as reasonably practicable after the Effective Time (but in any event no later than three (3) Business Days after the Effective Time, an amount in cash equal to the product of (A) the total number of shares of Company Common Stock subject to such Company Restricted Stock Unit immediately prior to the Effective Time, multiplied by (B) the Merger Consideration, less any applicable taxes required to be withheld with respect to such payment. Without limiting the foregoing, the Board of Directors of the Company or the appropriate committee thereof shall take all reasonable actions to effectuate the terms of this Section 2.05(c), including obtaining any required participant consent.

(d) Company Share Appreciation Rights. At the Effective Time, each outstanding share appreciation right entitling the holder thereof the right to receive shares of Company Common Stock (or a cash payment determined in relation to the value thereof) upon exercise issued pursuant to any applicable Stock Plan (each, a “Company Share Appreciation Right”), whether or not exercisable or vested, for which the exercise price per share of Company Common Stock is less than the Merger Consideration shall be canceled, and the Company shall pay each holder of any such right at or promptly after the Effective Time for each such Company Share Appreciation Right surrendered an amount in cash determined by multiplying (i) the excess, if any, of the Merger Consideration over the applicable exercise price of such right by (ii) the number of shares of Company Common Stock subject to such Company Share Appreciation Right (assuming full vesting of all Company Share Appreciation Rights). As of the Effective Time, each Company Share Appreciation Right for which the exercise price per share of Company Common Stock equals or exceeds the Merger Consideration shall be canceled and have no further effect, with no right to receive any consideration therefor. As of the Effective Time, all other Company Share Appreciation Rights shall no longer be outstanding and shall automatically cease to exist and shall become only the right to receive the consideration described in this Section 2.05(d), and, without limiting the foregoing, the Board of Directors of

the Company or the appropriate committee thereof shall take all reasonable actions to effectuate the terms of this Section 2.05(d), including obtaining any required participant consent.

Section 2.06. Adjustments. If, during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of Company Common Stock shall occur, as a result of any reclassification, recapitalization, stock split (including reverse stock split), merger, combination, exchange or readjustment of shares, subdivision or other similar transaction, or any stock dividend thereon with a record date during such period, the Merger Consideration and any other amounts payable pursuant to this Agreement shall be appropriately adjusted to eliminate the effect of such event on the Merger Consideration or any such other amounts payable pursuant to this Agreement.

The Company shall cause a meeting of its shareholders (the “Company Shareholder Meeting”) to be duly called and held as soon as reasonably practicable following confirmation from the SEC that it has no further comments to the Company Proxy Statement for the purpose of voting on the approval and adoption of this Agreement and the Merger. Subject to Section 6.03(b), the Board of Directors of the Company shall recommend approval and adoption of this Agreement and the Merger by the Company’s shareholders. Subject to the terms and conditions of this Agreement, an Adverse Recommendation Change permitted by Section 6.03(b) will not constitute a breach by the Company of this Agreement. In connection with the Company Shareholder Meeting, the Company shall (i) after consultation with Parent, promptly prepare and file with the SEC, use its reasonable best efforts to respond to the SEC’s comments or requests for additional information regarding and thereafter mail to its shareholders as promptly as practicable the Company Proxy Statement and all other proxy materials for such meeting, (ii) use its reasonable best efforts to obtain the Company Shareholder Approval, including soliciting proxies from its shareholders, and (iii) otherwise comply in all material respects with all legal requirements applicable to such meeting; provided, however, that the Company shall be permitted to delay or postpone convening the Company Shareholder Meeting (but not beyond the End Date) (a) if and to the extent necessary to obtain a quorum (either in person or by proxy) of its shareholders to take action at the Company Shareholder Meeting, (b) if and to the extent the Company determines in good faith that such delay, adjournment, or postponement is required by Applicable Law and/or (c) if in the good faith judgment of the Board of Directors of the Company or any committee thereof (after consultation with its legal counsel) such delay or postponement is necessary or appropriate, including in order to give the Company’s shareholders sufficient time to evaluate any new information or disclosure that the Company has sent them or otherwise made available to the Company’s shareholders by issuing a press release, filing materials with the SEC, or otherwise. The Company shall notify Parent promptly upon receipt of any comments or requests for information from the SEC or its staff or any other Governmental Authority for amendments or supplements to the Company Proxy Statement and shall supply Parent with copies of all correspondence between the Company or any of its Representatives, on the one hand, and the SEC, its staff or any other Governmental Authority, on the other hand, with respect to the Company Proxy Statement. Notwithstanding anything to the contrary stated above, prior to filing or mailing the Company Proxy Statement (including any amendment or supplement to the Company Proxy Statement) or responding to any comments or requests for additional information by the SEC or any other Governmental Authority with respect thereto, the Company

shall provide Parent with a reasonable opportunity to review and comment on such documents or responses and shall include in such documents or responses comments reasonably proposed by Parent.

(a) Subject to Section 6.03(b), the Company shall not, and shall cause its Subsidiaries not to, and shall direct its and their officers, directors, employees, investment bankers, attorneys, accountants, consultants and other authorized agents, advisors or representatives (collectively, “Representatives”) not to, directly or indirectly, (i) solicit, initiate or take any action to knowingly facilitate or encourage the submission of any proposal or offer that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (ii) enter into or participate in any discussions or negotiations with, furnish any information relating to the Company or any of its Subsidiaries or afford access to the business, properties, assets, books or records of the Company or any of its Subsidiaries to, any Third Party that to the knowledge of the Company is seeking to make, or has made, an Acquisition Proposal, (iii) withdraw, qualify or modify in a manner adverse to Parent or publicly propose to withdraw, qualify or modify in a manner adverse to Parent the Company Board Recommendation, or recommend, adopt or approve or publicly propose to recommend, adopt or approve an Acquisition Proposal (any of the foregoing in this clause (iii), whether taken by the Company’s Board of Directors or a committee thereof, an “Adverse Recommendation Change”), (iv) terminate, amend, modify, grant any waiver or release under or fail to enforce any standstill, confidentiality or similar agreement with respect to any equity or voting securities of the Company or any of its Subsidiaries, or publicly propose to do any of the foregoing, or (v) enter into any agreement in principle, letter of intent, term sheet, merger agreement, acquisition agreement or other similar instrument constituting or relating to an Acquisition Proposal. The Company shall, and shall cause its Subsidiaries to, and shall instruct their respective Representatives to, cease immediately and terminate any and all existing activities, discussions or negotiations, if any, with any Third Party conducted prior to the date of this Agreement with respect to any Acquisition Proposal and shall instruct any such Third Party (or its agents or advisors) in possession of confidential information about the Company that was furnished by or on behalf of the Company to return or destroy all such information.

(b) Notwithstanding the foregoing, at any time prior to the adoption of this Agreement by the Company’s shareholders, the Board of Directors of the Company, directly or indirectly through advisors, agents or other intermediaries, may, subject to compliance with Section 6.03(c), and Section 6.03(d), (i) engage in negotiations or discussions (including, as a part thereof, making any counterproposal or counter offer to) with any Third Party that, subject to the Company’s compliance with Section 6.03(a), has made after the date of this Agreement a Superior Proposal or an unsolicited Acquisition Proposal that the Board of Directors of the Company believes in good faith (after consultation with a financial advisor of nationally recognized reputation and outside legal counsel) is reasonably likely to lead to a Superior Proposal, (ii) thereafter furnish to such Third Party nonpublic information relating to the Company or any of its Subsidiaries pursuant to a confidentiality agreement with terms no less favorable to the Company than those contained in the Confidentiality Agreement (except for such changes specifically necessary for the Company to comply with its obligations under this Agreement and it being understood that the Company may enter into a confidentiality agreement without a standstill provision); provided 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, and (iii) make an Adverse Recommendation Change, but in each case referred to in the foregoing clauses (i) through (iii) only if the Board of Directors of the Company determines in good faith, after consultation with a financial advisor of nationally recognized reputation and outside legal counsel to the Company, that failure to take such action could reasonably be expected to be inconsistent with its fiduciary duties under Applicable Law. Nothing contained in this Agreement shall prevent the Board of Directors of the Company from (x) disclosing a position contemplated by Rule 14e-2(a) under the 1934 Act or Rule 14d-9 under the 1934 Act or (y) making any required disclosure to the Company’s shareholders if, in the good faith judgment of such Board of Directors, after consultation with its outside legal counsel, failure to disclose such information would reasonably be expected to violate its obligations under Applicable Law.

(c) The Board of Directors of the Company shall not take any of the actions referred to in clauses (i) through (iii) of Section 6.03(b) unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action, and the Company shall continue to advise Parent after delivery of such notice of the status and material terms of any discussions and negotiations with the Third Party. In addition, the Company shall notify Parent promptly (but in no event later than 48 hours) after receipt by the Company (or any of its Representatives) of any Acquisition Proposal, any inquiry that would be reasonably expected to lead to an Acquisition Proposal or of any request for information relating to the Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries by any Third Party that to the knowledge of the Company may be considering making, or has made, an Acquisition Proposal, which notice shall be provided in writing and shall identify the Person making and material terms and conditions of, any such Acquisition Proposal, inquiry or request (including all related transaction document(s) and any material changes thereto).

(d) Notwithstanding anything to the contrary in this Agreement, the Board of Directors of the Company shall not be permitted to approve or recommend another Acquisition Proposal unless (i) it has in all material respects complied with the provisions of this Section 6.03, (ii) the Board of Directors of the Company determines in good faith, after consultation with a financial advisor of nationally recognized reputation and outside legal counsel to the Company, that such Acquisition Proposal constitutes a Superior Proposal, (iii) prior to any such approval or recommendation of another Acquisition Proposal, the Company has provided a written notice to Parent (a “Notice of Superior Proposal”) that the Company intends to take such action and describing the material terms and conditions of the Superior Proposal that is the basis of such action, including with such Notice of Superior Proposal a copy of the relevant proposed transaction document(s) related to the Superior Proposal, (iv) during the three (3) Business Day period following Parent’s receipt of the Notice of Superior Proposal, the Company shall, and shall cause its financial and legal advisors, to negotiate with Parent and Merger Subsidiary (to the extent Parent and Merger Subsidiary desire to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute a Superior Proposal, (iv) following the end of such three (3) Business Day period, the Board of Directors of the Company shall have determined in good faith, taking into account any changes to the terms of this Agreement proposed in writing by Parent to the Company in response to the

Notice of Superior Proposal or otherwise, that the Superior Proposal giving rise to the Notice of Superior Proposal continues to constitute a Superior Proposal. Any amendment to the financial terms or any other material amendment of such Superior Proposal shall require a new Notice of Superior Proposal and the Company shall be required to comply again with the requirements of this Section 6.03(d) (provided that references to the three (3) Business Day period above shall be deemed reference to a forty-eight hour period).

(e) “Superior Proposal” means any Acquisition Proposal (with the percentages set forth in the definition of such term changed from 20% to 50%) made in writing and not solicited in violation of Section 6.03(a) that the Board of Directors of the Company determines in good faith, after consultation with a financial advisor of nationally recognized reputation and outside legal counsel and taking into account all the terms and conditions of the Acquisition Proposal would result in a transaction (i) that if consummated, is more favorable to the Company’s shareholders from a financial point of view than the Merger or, if applicable, any binding proposal by Parent capable of being accepted by the Company to amend the terms of this Agreement taking into account all of the terms and conditions of such proposal and this Agreement (including the expected timing and likelihood of consummation, taking into account any governmental and other approval requirements), (ii) that is reasonably capable of being completed on the terms proposed, taking into account the identity of the Person making the proposal, any approval requirements and all other financial, legal and other aspects of such proposal, and (iii) for which financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to be available by the Board of Directors of the Company.

Section 6.04. Access to Information; Confidentiality. From the date of this Agreement until the Effective Time and subject to Applicable Law, the Company shall, and shall cause its Subsidiaries to, upon reasonable notice and request, (i) give to Parent, its counsel, financial advisors, auditors and other authorized representatives reasonable access during normal business hours to its offices, properties, books and records, (ii) furnish to Parent, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (iii) instruct its employees, counsel, financial advisors, auditors and other authorized representatives to cooperate with Parent in its investigation. Any investigation pursuant to this Section shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the Company and its Subsidiaries. Nothing contained in this Section shall, prior to the Effective Time, require the Company to take any action that would, in the good faith judgment of the Company, constitute a waiver of the attorney-client or similar privilege or trade secret protection held by the Company or any of its Subsidiaries or violate confidentiality obligations owing to third parties; provided, however, that the Company shall make a good faith effort to accommodate any request from Parent for access or information pursuant to this Section in a manner that does not result in such a waiver or violation. All information furnished pursuant to this Section shall be subject to the confidentiality agreement, dated as of May 19, 2011 (as amended as of August 15, 2011), between Parent and the Company (the “Confidentiality Agreement”). The Company hereby consents to include the Sponsors and the Financing Sources as permitted “Representatives,” co-bidders, co-investors and/or financing sources under the Confidentiality Agreement.

(a) For six years after the Effective Time, Parent shall cause the Surviving Corporation to indemnify and hold harmless each current and former officer and director of the Company and its Subsidiaries and each Person who served as a fiduciary under or with respect to any employee benefit plan (within the meaning of Section 3(3) of ERISA) of the Company and its Subsidiaries (each, together with such person’s heirs, executors or administrators, an “Indemnified Person”) against any costs or expenses (including advancing attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Person to the fullest extent permitted by California Law or any other Applicable Law or provided under the Company’s amended and restated articles of incorporation, amended and restated bylaws and indemnification agreements with its officers and directors, each in effect on the date hereof; provided, however, that such advance shall be conditioned upon the Surviving Company’s receipt of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be ultimately determined by final judgment of a court of competent jurisdiction that the Indemnified Person is not entitled to be indemnified pursuant to this Section 7.01(a)), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, arbitration, proceeding or investigation in respect of or arising out of acts or omissions occurring or alleged to have occurred at or prior to the Effective Time to the fullest extent permitted by California Law or any other Applicable Law or provided under the Company’s amended and restated articles of incorporation, amended and restated bylaws and indemnification agreements with its officers and directors, each in effect on the date hereof; provided that such indemnification shall be subject to any limitation imposed from time to time under Applicable Law. In the event of any such action, Parent and the Surviving Corporation shall use commercially reasonable efforts to cooperate with the Indemnified Person in the defense of any such action.

(b) Parent shall cause the Surviving Corporation to continue in full force and effect for a period of six years from the Effective Time the provisions in existence in the Company’s and its Subsidiaries’ respective Organizational Documents and the Company’s indemnification agreements with its officers and directors in effect on the date of this Agreement regarding elimination of liability of directors, indemnification and exculpation of officers, directors and employees and advancement of expenses.

(c) For six years after the Effective Time, Parent shall cause the Surviving Corporation to provide officers’ and directors’ liability, fiduciary liability and similar insurance (collectively, “D&O Insurance”) in respect of acts or omissions occurring prior to the Effective Time covering each Indemnified Person covered as of the date of this Agreement by the Company’s D&O Insurance policies on terms with respect to coverage and amount no less favorable than those of such policies in effect on the date of this Agreement, as well as covering claims brought against each Indemnified Person under ERISA (or a six-year prepaid “tail policy” on terms and conditions reasonably acceptable to Parent providing coverage benefits and terms

no less favorable to the Indemnified Persons than the Company’s current such policies, as well as covering claims brought against each Indemnified Person under ERISA; for the avoidance of doubt, the Company may purchase such “tail policy” at its option prior to the Effective Time, and in such case, Parent shall cause such policy to be in full force and effect for its full term, and cause all obligations thereunder to be honored by the Surviving Corporation); provided that, in satisfying its obligation under this Section 7.01(c), the Surviving Corporation shall not be obligated to pay annual premiums in the aggregate in excess of 300% of the amount per annum the Company paid in its last full fiscal year, which amount the Company has disclosed to Parent prior to the date of this Agreement; provided further that, if the aggregate annual premiums of such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a D&O Insurance policy with the greatest coverage available, with respect to matters occurring prior to the Effective Time, for a cost not exceeding such amount.

(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 the 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 7.01.

(e) The rights of each Indemnified Person under this Section 7.01 shall be in addition to any rights such Person may have under the Organizational Documents of the Company or any of its Subsidiaries, or under California Law or any other Applicable Law or under any agreement of any Indemnified Person with the Company or any of its Subsidiaries. These rights shall survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Person.

(a) Parent agrees that, during the period commencing at the Effective Time and ending on the first anniversary of the Effective Time, the employees of the Company and its Subsidiaries as of the Effective Time who remain employees of the Surviving Corporation or any of its Subsidiaries following the Effective Time (the “Current Employees”) will be provided with (i) base salary and cash bonus opportunities (excluding long-term incentive opportunities and transaction or retention bonuses) which are no less favorable in the aggregate than the aggregate base salary and cash bonus opportunities (excluding long-term incentive opportunities and transaction or retention bonuses) provided by the Company and its Subsidiaries immediately prior to the Effective Time, (ii) retirement and welfare benefits and perquisites (excluding equity and equity-based benefits and defined benefit pension benefits, except as required by Applicable Law) that are substantially comparable in the aggregate to those provided by the Company and its Subsidiaries immediately prior to the Effective Time and (iii) severance benefits that are no less favorable than those set forth in any employment or severance agreement between the Company and any such Current Employee or any severance policy or practice of the Company or its Subsidiaries (as applicable) with respect to the Current Employees in effect on the date hereof listed on Section 7.02(a)(iii) of the Company Disclosure Schedule and made available to Parent. Notwithstanding the foregoing, Parent agrees that the terms and conditions of employment of

any employees who are covered by collective bargaining agreements or otherwise represented for purposes of collective bargaining by labor organizations shall be as provided in such collective bargaining agreements and applicable law.

(b) With respect to any employee benefit plan in which any Current Employee first becomes eligible to participate, on or after the Effective Time (the “New Company Plans”), Parent shall (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such Current Employee under any health and welfare New Company Plans in which such Current Employee may be eligible to participate after the Effective Time and (ii) recognize service of Current Employees (or otherwise credited by the Company or its Subsidiaries) accrued prior to the Effective Time for purposes of eligibility to participate in and vesting credit under (but not for the purposes of benefit accrual) any New Company Plan in which such Current Employees may be eligible to participate after the Effective Time, provided, however, that in no event shall any credit be given to the extent it would result in the duplication of benefits for the same period of service.

(c) Parent agrees to cause the Company following the Closing to maintain, and fulfill all of its obligations under, the Company’s 2007 Officer Severance Plan, as amended, and 2011 Officer Severance Plan, in each case as in effect as of the date hereof.

(d) No provision of this Section 7.02 (i) creates any third-party beneficiary or other rights, including any rights of continued employment or rights to a particular term of employment, for any employee of the Company or its Subsidiaries (including any beneficiary or dependent thereof) other than Parent, the Company and their respective successors and assigns, or (ii) constitutes an employment agreement or an amendment to or adoption of any employee benefit plan of or by any member of Parent, the Company or their Subsidiaries. Provided that Parent shall, in all events, continue to perform and satisfy its obligations under this Section 7.02, no provision of this Section 7.02 shall alter or limit the ability of Parent, the Company or any of their respective Subsidiaries and Affiliates to amend, modify or terminate any benefit plan, program, agreement or arrangement at any time assumed established, sponsored or maintained by any of them in accordance with the terms of such plan, program, agreement or arrangement and Applicable Law.

(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, all things necessary, proper or advisable under Applicable Law to consummate in the most expeditious manner possible the transactions contemplated by this Agreement, including (i) preparing and filing as promptly as practicable with any Governmental Authority or other third party all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents, (ii) taking all appropriate actions, and doing, or causing to be done, all things necessary, proper or advisable under Applicable

Laws to consummate and make effective the transactions contemplated by this Agreement, including using its reasonable best efforts to obtain and maintain all approvals, consents, registrations, permits, licenses, certificates, variances, exemptions, orders, franchises, authorizations and other confirmations of all Governmental Authorities or other third parties that are necessary, proper or advisable to consummate the transactions contemplated by this Agreement and to fulfill the conditions to the transactions contemplated by this Agreement, (iii) defending any actions, suits, claims, investigations or proceedings threatened or commenced by any Governmental Authority relating to the transactions contemplated by this Agreement, including seeking to have any stay, temporary restraining order or preliminary injunction entered by any Governmental Authority vacated or reversed, and (iv) cooperating to the extent reasonable with the other parties hereto in their efforts to comply with their obligations under this Agreement.

(b) In furtherance and not in limitation of the foregoing, each of Parent and the Company shall make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby (the “HSR Filing”) and all other filings under any applicable non-U.S. antitrust or competition laws deemed necessary, advisable or appropriate with respect to the transactions contemplated hereby as determined by Parent and the Company and listed in Section 4.03 of the Company Disclosure Schedule (together with the HSR Filing, the “Antitrust Filings”) as promptly as practicable and, with respect to the HSR Filing only, within ten (10) Business Days of the date of this Agreement and to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the Antitrust Filings and to use their reasonable best efforts to take all other actions necessary to cause the grant of clearance or the expiration or termination of the applicable waiting periods with respect to the Antitrust Filings as soon as practicable. In addition, Parent shall use its best efforts to take or cause to be taken all actions necessary, proper or advisable to obtain any consent, waiver, approval or authorizations relating to the HSR Act or similar non-U.S. laws that are required for the consummation of the transactions contemplated by this Agreement, which efforts shall include, without limitation, the proffer by Parent of its willingness to accept an order providing for the divestiture by Parent of such of its assets and businesses as are necessary to fully consummate the transactions contemplated by this Agreement, and an offer to hold separate such assets and businesses pending such divestiture. In the event that the FTC or the DOJ or any other Governmental Authority requires the divestiture or the holding separate by Parent of any assets, no adjustment shall be made to the Merger Consideration and Parent shall be required to hold such assets separate, or to divest them, as the case may be, following the Closing.

(a) The Company and Parent shall cooperate with one another (i) in connection with the preparation of the Company Proxy Statement, (ii) 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 Contracts to which the Company or any Subsidiary of the Company is a party in connection with the consummation of the transactions contemplated by this Agreement and (iii) in taking such actions or making any such filings, furnishing information required in connection therewith or with the Company Proxy Statement and seeking timely to obtain any such actions, consents, approvals or waivers.

(b) Each of Parent and the Company shall promptly notify the other party of any communication it receives from any Governmental Authority relating to the matters that are the subject of this Agreement and permit the other party to review in advance any proposed communication by such party to any Governmental Authority and shall provide each other with copies of all correspondence, filings or communications between them or any of their representatives and any Governmental Authority. Neither Parent nor the Company shall agree to participate in any meeting with any Governmental Authority in respect of any such filings, investigation or other inquiry unless it consults with the other party in advance and, to the extent permitted by such Governmental Authority, gives the other party the opportunity to attend and participate at such meeting.

(a) Parent and Merger Subsidiary shall use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain the Debt Financing on the terms and conditions described in the Debt Financing Commitment in the most expeditious manner possible, but in any event on or prior to the End Date, and shall not amend, modify or permit any amendment or modification to be made to, or any waiver of any provision or remedy under, the Financing Commitments if such amendment, modification or waiver would (x) reduce the aggregate amount of the Debt Financing (including by changing the amount of fees to be paid or original issue discount of the Debt Financing or similar fee) to the extent that Parent would then not have sufficient funds to pay the Merger Consideration, or (y) impose new or additional conditions, or otherwise amend, modify or expand any conditions, to the receipt of the Debt Financing, in each case, in a manner that would reasonably be expected to (1) impair, delay or prevent the Closing, (2) make the funding of the Debt Financing (or satisfaction of the conditions to obtaining the Debt Financing) less likely to occur, or (3) adversely impact the ability of Parent to enforce its rights against the other parties to the Debt Financing Commitment or the definitive agreements with respect thereto, the ability of Parent to consummate the transactions contemplated hereby or the likelihood of consummation of the transactions contemplated hereby. Subject to the limitations set forth in this Section 8.03 and provided that the representations set forth in Section 5.06 shall be true and correct giving effect to such replacement or amendment, Parent and Merger Subsidiary may replace or amend the Debt Financing Commitment to add lenders, lead arrangers, bookrunners, syndication agents or similar entities that have not executed the Debt Financing Commitment as of the date hereof, unless the addition of such additional parties, individually or in the aggregate, would be likely to result in Parent not having sufficient funds to pay the Merger Consideration or adversely impact the ability of Parent or Merger Subsidiary to consummate the transactions contemplated hereby on or prior to the End Date or the likelihood of the consummation of the transactions contemplated hereby or the availability of the Financing on or prior to the End Date. For purposes of this Section 8.03, references to “Financing” shall include the financing contemplated by the Financing Commitments as permitted to be amended or modified by this Section 8.03 and references to “Financing Commitments” or “Debt Financing Commitment” shall include such documents as permitted to be amended or modified by this Section 8.03. Without limiting the foregoing, Parent and Merger Subsidiary shall use their reasonable best efforts to (i) maintain in full force and effect the Debt Financing Commitment in accordance with its terms until the consummation of the transactions contemplated hereby, (ii) satisfy all conditions and covenants applicable to Parent and Merger Subsidiary in the Debt

Financing Commitment (including by consummating the financing pursuant to the terms of the Equity Financing Commitments) and otherwise comply with its obligations thereunder, in each case, that are within Parent’s or any of its Affiliates’ control, (iii) enter into definitive agreements with respect thereto on the terms and conditions (including any flex provisions) contemplated by the Debt Financing Commitment or on such other terms as shall be acceptable to Parent and the Financing Sources (as long as such terms do not adversely affect the amount of financing to be provided or cause the funding of the Debt Financing to be less likely to occur), (iv) consummate the Financing at or prior to the Closing, (v) fully enforce their rights under the Debt Financing Commitment, including by bringing legal action or other appropriate proceedings, against any Financing Source to enforce their respective rights under the Debt Financing Commitment and, as may be appropriate, to fund in accordance with their respective commitments if all conditions to funding the Debt Financing in the applicable document have been satisfied or waived, and (vi) subject to the satisfaction or waiver of the conditions set forth in the Debt Financing Commitment, cause the lenders and other Persons providing Financing to fund on the Closing Date the Financing contemplated to be funded on the Closing Date by the Debt Financing Commitment (or such lesser amount as may be required to consummate the Merger and the other transactions contemplated hereby). Without limiting the generality of the foregoing, Parent and Merger Subsidiary shall give the Company prompt written notice: (A) of any breach or default (or any event or circumstance that, with or without notice, lapse of time or both, would reasonably be expected to give rise to any breach or default) by any party to any Financing Commitment or definitive document related to the Financing of which Parent or its Affiliates becomes aware; (B) of the receipt of any written notice or other written communication from any Person with respect to any (x) actual or potential breach, default, termination or repudiation by any party to any Financing Commitment or any definitive document related to the Financing or any provisions of the Financing Commitments or any definitive document related to the Financing or (y) material dispute or disagreement between or among any parties to any Financing Commitment or any definitive document related to the Financing which would create a risk that the funding of the Debt Financing would be less likely to occur (but excluding, for the avoidance of doubt, any ordinary course negotiations with respect to the terms of the Financing or any definitive agreement with respect thereto); and (C) if for any reason Parent or Merger Subsidiary believes in good faith it will not be able to obtain all or any portion of the Financing on the terms or in the manner contemplated by the Financing Commitments or the definitive documents related to the Financing; provided, that in no event will Parent or Merger Subsidiary be under any obligation to disclose any information that is subject to attorney-client or similar privilege if Parent and Merger Subsidiary shall have used their reasonable best efforts to disclose such information in a way that would not waive such privilege. If any portion of the Debt Financing becomes unavailable on substantially the terms and conditions contemplated in the Debt Financing Commitment, Parent shall use its reasonable best efforts to arrange and obtain alternative financing from alternative sources on terms and conditions that are no less favorable to Parent, taken as a whole, than those set forth in the Debt Financing Commitment, in an amount sufficient to consummate the transactions contemplated by this Agreement as promptly as practicable following the occurrence of such event. Parent will furnish to the Company correct and complete copies of any Debt Financing Commitment and ancillary documents thereto (redacted to the extent necessary to comply with confidentiality agreements, provided that such redacted information does not relate to the amounts or conditionality of, or contain any conditions precedent to, the funding of the Debt Financing).

(b) Prior to the Closing, the Company shall, and shall cause its Subsidiaries and Representatives to use its reasonable best efforts to provide to Parent and Merger Subsidiary, at Parent’s sole expense, all cooperation reasonably requested by Parent in connection with the Debt Financing and causing the conditions in the Debt Financing Commitment to be satisfied, including, without limitation, (i) furnishing Parent and Merger Subsidiary and their Financing Sources with the financial statements and financial data of the Company required by paragraph 5 of Exhibit C of the Debt Financing Commitment, (ii) participating in a reasonable number of meetings (including customary one-on-one meetings with the parties acting as lead arrangers or agents for, and prospective lenders and purchasers of, the Debt Financing and the executive chairman, chief executive officer, chief operating officer, chief financial officer and general counsel of the Company and other members of senior management and Representatives of the Company), presentations, road shows, due diligence sessions, drafting sessions and sessions with rating agencies in connection with the Debt Financing, (iii) assisting Parent and its Financing Sources in the preparation of customary offering memoranda, bank information memoranda, authorization letters, confirmations and undertakings in connection with the offering memoranda and the bank information memoranda and lender presentations relating to the Debt Financing, (iv) providing and executing documents as may be reasonably requested by Parent, including (A) documents requested by the Parent or its Financing Sources relating to the repayment of the existing Indebtedness of the Company and its Subsidiaries and the release of related Liens, including customary payoff letters and (to the extent required) evidence that notice of such repayment has been timely delivered to the holders of such debt; (B) all documentation and other information required by bank regulatory authorities under applicable “know-your-customer” and anti-money laundering rules and regulations, including the Patriot Act; (C) a certificate of the chief financial officer of the Company with respect to solvency matters; and (D) agreements, documents or certificates that facilitate the creation, perfection or enforcement of Liens securing the Debt Financing (including original copies of all certificated securities (with transfer powers executed in blank), control agreements, surveys, title insurance, landlord consent and access letters) as are reasonably requested by the Parent or its Financing Sources, (vi) executing and delivering any pledge and security documents and otherwise facilitating the pledging of collateral, (vii) cooperating with the Financing Sources’ due diligence investigation and evaluation of the Company’s assets for the purpose of establishing collateral arrangements, to the extent customary and reasonable and not unreasonably interfering with the business of the Company, and (viii) providing any other documents, instruments, certificates or information as may be reasonably requested in connection with the Debt Financing; provided, however, that, (1) irrespective of the above, no obligation of the Company or any of its Subsidiaries under any certificate, document or instrument (other than the authorization and representation letters referred to above) shall be effective until the Effective Time and none of the Company or any of its Subsidiaries shall be required to take any action under any certificate, document or instrument that is not contingent upon the Closing (including the entry into any agreement that is effective before the Effective Time) or that would be effective prior to the Effective Time and (2) nothing herein shall require such cooperation to the extent it would interfere unreasonably with the business or operations of the Company or its Subsidiaries. None of the Company or any of its Subsidiaries shall be required to bear any cost or expense or to pay any commitment or other similar fee or make any other payment (other than reasonable out-of-pocket costs) in connection with the Financing or any of the foregoing prior to the Effective Time. The Company hereby consents to the use of its and its Subsidiaries’ logos in connection with the Debt Financing;

provided that such logos shall be used solely in a manner that is not intended or reasonably likely to harm, disparage or otherwise adversely affect the Company or any of its Subsidiaries. If this Agreement is terminated prior to the Effective Time, Parent shall, promptly upon request by the Company, reimburse the Company for all documented and reasonable out-of-pocket costs incurred by the Company or its Subsidiaries in connection with this Section 8.03(b).

(c) Parent and Merger Subsidiary acknowledge and agree that the obtaining of the Financing, or any alternative financing, is not a condition to Closing.

Section 8.04. Public Announcements. Except with respect to the announcement of any Adverse Recommendation Change (or proposed Adverse Recommendation Change) in accordance with Section 6.03, Parent and the Company shall consult with each other before issuing any press release, 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 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, make any such other public statement or schedule any such press conference or conference call before such consultation.

Section 8.05. Stock Exchange De-listing. Prior to the Closing Date, the Company shall cooperate with Parent and use its commercially reasonable efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under Applicable Laws and rules and policies of NASDAQ to enable the de-listing by the Surviving Corporation of the Company Common Stock from NASDAQ and the deregistration of the Company Common Stock under the 1934 Act as promptly as practicable after the Effective Time, and in any event no more than five (5) Business Days after the Closing Date.

Section 8.06. Further Assurances. 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.

Section 8.07. Notices of Certain Events. Each of the Company and Parent shall promptly notify the other of:

(a) any notice or other communication from any Governmental Authority in connection with the transactions contemplated by this Agreement;

(b) any inaccuracy of any representation or warranty contained in this Agreement at any time during the term of this Agreement that could reasonably be expected to give rise to a risk of termination set forth in Section 10.01(c)(ii) or Section 10.01(d)(ii), as the case may be; and

(c) any failure of that party to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder that could reasonably be expected to give rise to a right of termination set forth in Section 10.01(c)(ii) or Section 10.01(d)(ii), as the case may be;

provided, however, that the delivery of any notice pursuant to this Section 8.07 shall not limit or otherwise affect the remedies available hereunder to the party receiving that notice.

Section 8.08. Director Resignations. The Company shall obtain and deliver to Parent at the Closing evidence reasonably satisfactory to Parent of the resignation, effective as of the Effective Time, of those directors of the Company or any Subsidiary of the Company designated by Parent to the Company in writing at least five (5) Business Days prior to the Closing.

Section 8.09. Takeover Statutes. If any Takeover Statute is or may become applicable to the Merger or the other transactions contemplated by this Agreement, the Company and its Board of Directors shall grant such approvals and take such actions as are necessary so that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute or regulation on such transactions. Neither the Company nor its Board of Directors (or any committee thereof) shall take any action to permit any Takeover Statute to become applicable to the Merger or other transactions contemplated by this Agreement.

Section 8.10. Shareholder Litigation. In the event that any shareholder litigation related to this Agreement, the Merger or the other transactions contemplated by this Agreement is brought against the Company and/or the members of the Board of Directors of the Company prior to the Effective Time, the Company shall promptly notify Parent and shall use its reasonable best efforts to keep Parent reasonably informed with respect to the status thereof. The Company shall reasonably consult with Parent with respect to the defense or settlement of any such shareholder litigation. Neither the Company nor any Subsidiary or Representative of the Company shall compromise, settle, come to an arrangement regarding or agree to compromise, settle or come to an arrangement regarding any such shareholder litigation or consent to the same unless Parent shall have consented in writing (which consent shall not be unreasonably withheld, conditioned or delayed).

Section 8.11. Rule 16b-3. The Company shall, and shall be permitted to, take all actions as may be reasonably requested by any party hereto to cause any dispositions of equity securities (including derivative securities) of the Company by each individual who is a director or officer of the Company, and who would otherwise be subject to Rule 16b-3 under the 1934 Act, to be exempt under Rule 16b-3 under the 1934 Act.

Section 8.12. Credit Facility Termination. On or prior to the fifth Business Day prior to the Effective Time, the Company shall deliver to Parent a fully executed copy of a payoff letter, in customary form, from Wells Fargo Bank, N.A., as administrative agent under that certain Amended and Restated Credit Agreement, dated as of January 13, 2011, by and among the Company, Tekelec International, SPRL, and the lenders party thereto (the “Credit Agreement”), which payoff letter shall (i) indicate the total amount required to be paid to fully satisfy all principal, interest, prepayment premiums, penalties, breakage costs or similar obligations related

to any Obligations (as defined in the Credit Agreement) as of the anticipated Closing Date (and the daily accrual thereafter) (the “Payoff Amount”), (ii) state that upon receipt of the Payoff Amount, the Credit Agreement and related instruments evidencing the Credit Agreement shall be terminated and any stock certificates and other physical collateral shall be returned, and (iii) state that all Liens and all guarantees in connection therewith relating to the assets and properties of the Company or any of its Subsidiaries securing such Obligations shall be, upon the payment of the Payoff Amount on the Closing Date, released and terminated. The Company shall, and shall cause its Subsidiaries to, use reasonable best efforts to deliver all notices and take all other actions, including with respect to the backstop or termination of any letters of credit issued under the Credit Agreement and any hedging or swap obligations secured under the Credit Agreement, to facilitate the termination of commitments under the Credit Agreement, the repayment in full of all Obligations then outstanding thereunder (using funds arranged by Parent or Merger Subsidiary) and the release of all Liens and termination of all guarantees in connection therewith on the Closing Date (such termination, repayment and release, the “Credit Facility Termination”); provided that in no event shall this Section 8.12 require the Company or any of its Subsidiaries to cause such Credit Facility Termination unless the Closing shall occur substantially concurrently and the Company or its Subsidiaries have received funds from Parent to pay in full the Payoff Amount.

(a) Parent and Merger Subsidiary acknowledge that they have committed to provide, subject to the Equity Financing Commitments, the Equity Financing, including (i) maintaining in effect the Equity Financing Commitments, (ii) ensuring the accuracy of all representations and warranties of Parent and Merger Subsidiary set forth in the Equity Financing Commitments, (iii) complying with all covenants and agreements of Parent and Merger Subsidiary set forth in the Equity Financing Commitments, (iv) satisfying on a timely basis all conditions applicable to Parent and Merger Subsidiary set forth in the Equity Financing Commitments that are within their control, (v) upon satisfaction of such conditions and other conditions set forth in Section 9.01 and Section 9.02 (other than those conditions that by their nature are to be satisfied at the Closing, subject to the fulfillment or waiver of those conditions), consummating the financing contemplated by the Equity Financing Commitments at or prior to the Closing (and in any event prior to the End Date), and (vi) fully enforcing the obligations of the investor parties thereto and their investment affiliates (and the rights of Parent and Merger Subsidiary) under the Equity Financing Commitments.

(b) Neither Parent nor Merger Subsidiary shall amend, alter, or waive, or agree to amend, alter or waive (in any case whether by action or inaction), any term of the Equity Financing Commitments without the prior written consent of the Company. Each of Parent and Merger Subsidiary agrees to notify the Company promptly if at any time prior to the Closing Date (i) the Equity Financing Commitments expire or are terminated for any reason (or if any person attempts or purports to terminate the Equity Financing Commitments, whether or not such attempted or purported termination is valid), (ii) the investor parties thereto refuse to provide or express an intent in writing to refuse to provide the full Equity Financing on the terms set forth in the Equity Financing Commitments or (iii) for any reason Parent or Merger Subsidiary no longer believe in good faith that it will be able to obtain all or any portion of the Equity Financing on the terms set forth in the Equity Financing Commitments.

Section 8.15. Loss Carryback. The Company shall use commercially reasonable efforts to, as promptly as practicable after the date of this Agreement, file a claim for a refund of U.S. federal income taxes paid by the Company with respect to its 2008 and/or 2009 tax year by carrying back tax losses generated in the 2010 tax year to such year(s), to the extent permitted by Law.

(i) the Merger has not been consummated on or before April 30, 2012 (the “End Date”); provided, that the right to terminate this Agreement pursuant to this Section 10.01(b)(i) shall not be available to any party whose breach of any provision of this Agreement results in the failure of the Merger to be consummated by such time;

(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.

transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision,

(e) In the event that the Company Termination Fee becomes payable and is paid by the Company pursuant to this Section 11.04, the right to receive the Company Termination Fee shall constitute each of Parent’s and Merger Subsidiary’s and each of their respective Affiliates’ and representatives’ sole and exclusive remedy.

(f) Notwithstanding anything to the contrary in this Agreement, in the event Parent and Merger Subsidiary fail to effect the Closing or otherwise breach this Agreement or fail to perform hereunder, then, except as and only to the extent expressly permitted by Section 11.13, the Company’s sole and exclusive remedy (whether at law, in equity, in contract, in tort or otherwise) against the Parent Related Parties in respect of this Agreement, any Contract executed in connection herewith (including the Equity Financing Commitments, the Limited Guarantee and the Debt Financing Commitment, but excluding the Confidentiality Agreement) and the transactions contemplated hereby and thereby shall be to terminate this Agreement in accordance with (and subject to the conditions of) Article 10 and collect, if due, the Parent Termination Fee and any reimbursement obligations under Section 8.03(b) and the Limited Guarantee from Parent or Guarantor pursuant to the Limited Guarantee, and upon payment of such amounts in accordance with Section 8.03(b) and this Section 11.04, except as provided in Section 11.13, (A) no Parent Related Party shall have any further liability or obligation relating to or arising out of this Agreement, any Contract executed in connection herewith (including the Equity Financing Commitments, the Limited Guarantee and the Debt Financing Commitment, but excluding the Confidentiality Agreement) or any of the transactions contemplated hereby or thereby, (B) neither the Company nor any other Company Related Party shall be entitled to bring or maintain any Action against Parent, Merger Subsidiary or any other Parent Related Party arising out of or in connection with this Agreement, any Contract executed in connection herewith (including the Equity Financing Commitments, the Limited Guarantee and the Debt Financing Commitment, but excluding the Confidentiality Agreement) or any of the transactions contemplated hereby or thereby (or the abandonment or termination thereof) or any matters forming the basis for such termination, and (C) the Company shall use its reasonable best efforts to cause any Actions pending in connection with this Agreement, any Contract executed in connection herewith (including the Equity Financing Commitments, the Limited Guarantee and the Debt Financing Commitment, but excluding the Confidentiality Agreement) or any of the transactions contemplated hereby or thereby, to the extent maintained by the Company or another Company Related Party against Parent, Merger Subsidiary or any other Parent Related Party, to be dismissed with prejudice promptly following the payment of any such amounts. For the avoidance of doubt, (x) under no circumstances shall the Company be entitled to collect the Parent Termination Fee on more than one occasion and (y) under no circumstances shall the Company be permitted or entitled to receive both a grant of specific performance of the obligation to close contemplated by Section 11.13 that results in the Merger occurring and any money damages, including the Parent Termination Fee. In connection with any loss suffered as a result of any breach of any representation, covenant or agreement in this Agreement or the failure of the Merger to be consummated, or in respect of any oral representation made or alleged to have been made in connection herewith, in each case, other than in a circumstance in which the Company is permitted to terminate this Agreement and receive the Parent Termination Fee pursuant to this Section 11.04 or any reimbursement obligations under Section 8.03(b) or the

Limited Guarantee, the Company agrees that the maximum aggregate liability of Parent and Merger Subsidiary shall be limited to an amount equal to the amount of the Parent Termination Fee plus any reimbursement obligations under Section 8.03(b) and the Limited Guarantee, and in no event shall the Company seek to recover any money damages in excess of such amount. In no event shall the Company seek equitable relief or to recover monetary damages from any Parent Related Party in connection with the transactions contemplated by this Agreement other than (i) Parent and Merger Subsidiary pursuant to (and subject to the conditions of) this Agreement and (ii) monetary damages from the Guarantor pursuant to (and subject to the conditions of) the Limited Guarantee.

Section 11.05. Disclosure Schedule References. If and to the extent any information required to be furnished in any Section of the Company Disclosure Schedule is contained in this Agreement or in any other Section of the Company Disclosure Schedule, such information shall be deemed to be included in all Sections of the Company Disclosure Schedule in which the information would otherwise be required to be included to the extent that the disclosure is reasonably apparent from its face to be applicable to such other Sections of the Company Disclosure Schedule. Disclosure of any fact or item in any Section of the Company Disclosure Schedule shall not be considered an admission by the Company that such item or fact (or any non-disclosed item or information of comparable or greater significance) represents a material exception or fact, event or circumstance or that such item has had or would reasonably be expected to have a Material Adverse Effect on the Company, that such item or fact will in fact exceed any applicable threshold limitation set forth in the Agreement and shall not be construed as an admission by the Company of any non-compliance with, or violation of, any third party rights (including but not limited to any intellectual property rights) or any Applicable Law of any Governmental Authority, such disclosures having been made solely for the purposes of creating exceptions to the representations made herein or of disclosing any information required to be disclosed under the Agreement.

(a) The provisions of this Agreement shall be binding upon and, except as provided in Section 7.01, shall inure to the benefit of the parties hereto and their respective successors and assigns. No provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder, including the right to rely upon the representations and warranties set forth herein, upon any Person other than the parties hereto and their respective successors and assigns, except (i) as provided in Section 7.01, (ii) for the provisions of Section 11.04(f) and Section 11.08(b), which shall also be for the benefit of the Financing Sources and their respective Affiliates, employees, directors, controlling persons, officers, agents, attorneys, stockholders or partners or assignees of any of the foregoing and (iii) for the provisions of Article 2 which, from and after the Effective Time, shall be for the benefit of the holders of Company Common Stock, Company Restricted Stock Units, Company Stock Options and Company Share Appreciation Rights as of the Effective Time.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of each other party hereto; provided, however, that Parent or Merger Subsidiary may assign its rights, interests or obligations under

this Agreement to any Subsidiary of Parent without the consent of the other parties hereto, but no such assignment shall relieve the assigning party of its obligations hereunder.

Section 11.07. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state; provided, that the laws of the State of California shall govern with respect to the Merger.

(a) Subject to Section 11.08(b) below, the parties hereto agree that any Action 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 shall be brought in the Delaware Court of Chancery or, if such court shall not have jurisdiction, any federal court sitting in Delaware (the “Chosen Courts”), so long as one of such courts shall have subject matter jurisdiction over such Action, and that any such Action arising out of this Agreement shall be deemed to have arisen from a transaction of business in the State of Delaware, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Action 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 Action in any such court or that any such Action brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or Action 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 11.01 shall be deemed effective service of process on such party.

(b) Each party to this Agreement acknowledges and irrevocably agrees (i) that any Action, whether in law or in equity, whether in contract or in tort or otherwise, involving any of the Financing Sources or any Affiliate thereof arising out of or relating to this Agreement or the Debt Financing Commitment or the performance thereunder shall be subject to the exclusive jurisdiction of any state or federal sitting in the Borough of Manhattan in the City and State of New York, and any appellate court from any thereof (it being understood and agreed that, notwithstanding the selection of such exclusive jurisdiction, the interpretation of “Material Adverse Effect” and whether there shall have occurred a “Material Adverse Effect” shall be determined in accordance with the laws of the State of Delaware, without regard to the conflict of laws rules of such state), (ii) not to bring or permit any of their Affiliates to bring or support anyone else in bringing any such Action in any other court and (iii) to waive any right to trial by jury in respect of any such Action.

Section 11.09. 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.

Section 11.10. Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of a signed counterpart

of a signature page of this Agreement by facsimile or by PDF file (portable document format file) shall be as effective as delivery of a manually signed counterpart of this Agreement. 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 parties 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).

Section 11.11. Entire Agreement. This Agreement and the Confidentiality Agreement constitute the entire agreement between the parties with respect to the subject matter thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof.

Section 11.12. 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 11.13. Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that the parties shall be entitled, without posting a bond or similar indemnity, to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in the Chosen Courts, in addition to any other remedy to which they are entitled at law or in equity. Notwithstanding anything in this Agreement to the contrary but subject to the provisions of Section 11.04(f), however, the parties hereby acknowledge and agree that the Company shall be entitled to specific performance to cause Parent and/or Merger Subsidiary (A) to enforce the terms of the Debt Financing Commitment (including by demanding Parent and/or Merger Subsidiary to file one or more lawsuits against the sources of Debt Financing to fully enforce such sources’ obligations thereunder and Parent’s, Holdings’ and Merger Sub’s rights thereunder) and (B) to draw down the full proceeds of the Equity Financing pursuant to the terms and conditions of the Equity Financing Commitments and to cause Parent and/or Merger Subsidiary to effect the Closing in accordance with Section 2.01, in each case, if and only if (a) all conditions in Section 9.01 and Section 9.02 have been satisfied (other than those conditions that, by their nature, are to be satisfied at the Closing (and which are, at the time that the Company seeks specific performance pursuant to this Section 11.13, capable of being satisfied if the Closing were to occur at such time) or the failure of which to be satisfied is attributable primarily to a breach by Parent or Merger Subsidiary of their respective representations, warranties, covenants or agreements contained in this Agreement), (b) the Debt Financing has been funded or will be funded at the date the Closing is required to have

occurred pursuant to Section 2.01(b) upon delivery of a drawdown notice by Parent, Holdings or Merger Subsidiary and/or notice from Parent that the Equity Financing will be funded at such date, (c) Parent and Merger Subsidiary fail to complete the Closing by the date the Closing is required to have occurred pursuant to Section 2.01(b), (d) the Company has confirmed in writing to Parent that all conditions set forth in Section 9.03 have been satisfied or that it would be willing to waive any unsatisfied conditions in Section 9.03 for purposes of consummating the Merger, and (e) such specific performance would result in the consummation of the Merger in accordance with this Agreement substantially contemporaneously with the consummation of the Debt Financing and the Equity Financing. For the avoidance of doubt, (y) in no event shall the exercise of the Company’s right to seek specific performance or other equitable relief pursuant to this Section 11.13 reduce, restrict or otherwise limit the Company’s right to terminate this Agreement pursuant to Section 10.01(d)(ii) or Section 10.01(d)(iii) and be paid the Parent Termination Fee; provided, that under no circumstances shall the Company be permitted or entitled to receive both a grant of specific performance that results in the Merger occurring pursuant to this Section 11.13 and the payment of all or any portion of the Parent Termination Fee, and (z) the Company’s right to seek specific performance pursuant to this Section 11.13 shall include the right of the Company to cause Parent and Merger Subsidiary to fully enforce the terms of the Equity Financing Commitments, including by requiring Parent and Merger Subsidiary to file one or more lawsuits against any Sponsor to fully enforce the obligations of such Sponsor under an Equity Financing Commitment. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (x) the other party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
