Section 1.5 Surrender of Certificates .

(a) Prior to the Closing, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent (the “ Paying Agent ”) for the holders of Shares and to receive the funds to which holders of such Shares shall become entitled pursuant to this Agreement. The agreement pursuant to which Parent designates the Paying Agent shall be in form and substance reasonably acceptable to the Company and Parent. Prior to the Closing, Parent shall deposit or cause to be deposited with the Paying Agent sufficient funds to pay the aggregate Merger Consideration payable in respect of the Shares pursuant to Section 1.4(a)(iii) (the “ Payment Fund ”). With respect to any Dissenting Shares, Parent shall only be required to deposit or cause to be deposited with the Paying Agent funds sufficient to pay the aggregate Merger Consideration payable in respect of such Dissenting Shares if the holder thereof fails to perfect or effectively withdraws or loses its right to appraisal under the DGCL. To the extent the Payment Fund diminishes for any reason below the level required to make prompt payment of the amounts described in the preceding sentences, Parent and Merger Sub shall, or shall cause the Surviving Corporation to, promptly replace or restore the lost portion of such fund so as to ensure that it is maintained at a level sufficient to make such payments. The Payment Fund shall be invested by the Paying Agent as directed by Parent; provided , however , that (i) no such investment or losses thereon shall relieve Parent from making the payments required by this Article I or affect the amount of Merger Consideration payable in respect of the Shares and following any losses Parent shall promptly provide additional funds to the Paying Agent in the amount of any such losses, (ii) no such investment shall have maturities that could prevent or delay payments to be made pursuant to this Agreement, and (iii) such investments shall be in (A) short-term direct obligations of or guaranteed by the United States of America, (B) short-term commercial paper obligations, (C) certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $5 billion, or (D) money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of investment. Any and all interest or other amounts earned with respect to such funds shall be paid to Parent or its designee, except as provided in Section 1.5(c) . The Payment Fund shall not be used for any other purpose. The Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) pay all charges and expenses, including those of the Paying Agent, in connection with the exchange of Shares and the payment of the Merger Consideration in respect of the Shares.

(b) Promptly after the Effective Time (and in any event within two (2) Business Days thereafter), Parent and the Surviving Corporation shall cause the Paying Agent to mail to each Person who was, immediately prior to the Effective Time, a holder of record of Shares entitled to receive any Merger Consideration pursuant to Section 1.4(a)(iii) (i) a form of letter of transmittal (which shall be in a form reasonably acceptable to the Company and Parent and shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof as provided in Section 1.5(f) ) to the Paying Agent) and (ii) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu thereof as provided in Section 1.5(f) ) or Book-Entry Shares pursuant to such letter of transmittal. Upon (A) surrender to the Paying Agent of Certificates (or affidavits of loss in lieu thereof as provided in Section 1.5(f) ), together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required pursuant to such instructions,

4

or (B) 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 Book-Entry Shares, the holder of such Certificates or Book-Entry Shares, as applicable, shall be entitled to receive in exchange therefor the applicable Merger Consideration for each Share formerly evidenced by such Certificates or Book-Entry Shares, as applicable, and such Certificates and Book-Entry Shares, as applicable, shall then be canceled. No interest shall accrue or be paid on the applicable Merger Consideration payable upon the surrender of any Certificates or Book-Entry Shares for the benefit of the holder thereof. If the payment of any Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificates formerly evidencing Shares are registered on the stock transfer books of the Company, it shall be a condition of payment that the Certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the Person requesting such payment shall have paid all transfer and other similar Taxes required by reason of the payment of the applicable Merger Consideration to a Person other than the registered holder of the Certificate surrendered, or shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not applicable. Payment of the applicable Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered.

(c) At any time following the date that is twelve (12) months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of Certificates or Book-Entry Shares (including all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat and other similar Law) as general creditors thereof with respect to the applicable Merger Consideration that may be payable upon due surrender of the Certificates or Book-Entry Shares held by them. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of Certificates or Book-Entry Shares for the applicable Merger Consideration delivered in respect of such share to a public official pursuant to any applicable abandoned property, escheat or other similar Law. If any Certificate or Book-Entry Share has not been surrendered or transferred prior to the date on which the applicable Merger Consideration in respect thereof would otherwise escheat to or become the property of any Governmental Entity, then any such Merger Consideration in respect of such Certificate or Book-Entry Share shall become, to the extent permitted by applicable Law, the property of the Surviving Corporation, free and clear of any claims or interest of any Person previously entitled thereto.

(d) No dividends or other distributions with respect to capital stock of the Surviving Corporation with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Certificates or Book-Entry Shares.

(e) At the Effective Time, the stock transfer books of the Company with respect to Shares shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided herein or by applicable Law. If, after the Effective Time, any Certificate or Book-Entry Share is presented to the Surviving Corporation, Parent or

5

the Paying Agent for surrender or transfer, as applicable, it shall be canceled and, subject to compliance with this Section 1.5 , exchanged for the cash amount in immediately available funds to which the holder thereof is entitled pursuant to this Section 1.5 .

(f) If any Certificate has been lost, stolen or destroyed, then, upon the making of an effective affidavit (in form and substance reasonably acceptable to Parent and the Paying Agent) of that fact by the Person claiming such Certificate to be lost, stolen or destroyed to the Paying Agent (and, if required by Parent or the Paying Agent, the posting by such Person of a bond, in such reasonable and customary amount and upon such terms as may be reasonably required by Parent or the Paying Agent, as indemnity against any claim that may be made against it with respect to such Certificate), Parent shall cause the Paying Agent to issue in exchange for such lost, stolen or destroyed Certificate a check in the amount (after giving effect to any required Tax withholdings as provided in Section 1.8 ) equal to the Merger Consideration payable in respect of the Shares formerly represented by such lost, stolen or destroyed Certificate.

Section 1.6 Appraisal Rights .

(a) Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time, and held by holders who are entitled to appraisal rights under Section 262 of the DGCL and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the Effective Time, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL (the “ Dissenting Shares ”), shall not be converted into the right to receive Merger Consideration, but shall, by virtue of the Merger, be entitled to only such consideration as shall be determined pursuant to Section 262 of the DGCL; provided , that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal and payment under the DGCL, such holder’s Shares shall be deemed to have been converted as of the Effective Time into the right to receive, without interest, the Merger Consideration (less any amounts entitled to be deducted or withheld pursuant to Section 1.8 ), and such Shares shall not be deemed to be Dissenting Shares. The Company shall give Parent (i) prompt notice of any written demands for appraisal of any Shares or written withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to rights to be paid the “fair value” of Dissenting Shares, and (ii) the right to participate in any negotiations with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, voluntarily make or agree to make any payment with respect to any demands for appraisals of capital stock of the Company, offer to settle or settle any such demands, approve any withdrawal of any such demands, or agree to do any of the foregoing. The Company shall provide each of the holders of Shares with the notice contemplated by Section 262 of the DGCL as part of the Proxy Statement.

(b) If the Surviving Corporation makes any payment with respect to the Dissenting Shares, then any portion of the Merger Consideration relating to such Dissenting Shares held in the Payment Fund shall be delivered by the Paying Agent to the Surviving Corporation upon demand.

Section 5.5 Directors’ and Officers’ Insurance and Indemnification . For not less than six (6) years from and after the Effective Time, Parent shall cause the Surviving Corporation to indemnify and hold harmless all past and present directors and officers of the Company and the Company Subsidiaries (collectively, the “ Indemnified Parties ”) against any costs or expenses (including advancement of expenses to the extent provided in the Company Governing Documents), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, investigation, suit or proceeding in respect of acts or omissions occurring or alleged to have occurred at or prior to the Effective Time (including acts or omissions occurring in connection with the adoption of this Agreement,

43

the consummation of the Merger or the consummation of any of the other Transactions), whether asserted or claimed prior to, at or after the Effective Time, in connection with such persons serving as an officer or director of the Company or any of the Company Subsidiaries or serving at the request of the Company or any of the Company Subsidiaries as a director, officer, employee or agent of another Person, to the fullest extent provided pursuant to the Company Governing Documents or the organizational documents of any Company Subsidiary or any other agreement, if any, in existence on the date of this Agreement. The Parties agree that for six (6) years after the Effective Time all rights to elimination or limitation of liability, indemnification and advancement of expenses for acts or omissions occurring or alleged to have occurred at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of the Indemnified Parties as provided in the Company Governing Documents or the organizational documents of any Company Subsidiary or any other agreement shall survive the Merger and shall continue in full force and effect. Parent shall cause the Surviving Corporation to provide, for an aggregate period of not less than six (6) years from the Effective Time, the Company’s current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time (the “ D&O Insurance ”) that is no less favorable than the Company’s existing policy as of the date of this Agreement or, if insurance coverage that is no less favorable is unavailable, the best available coverage; provided , however , that the Surviving Corporation shall not be required to pay an annual premium for the D&O Insurance in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement as set forth in Section 2.16 of the Company Disclosure Schedule or, if less, the cost of a policy providing coverage on the same terms as the Company’s existing policy as of the date of this Agreement; provided , further , that, at the Company’s option, in lieu of the foregoing insurance coverage, the Company or Surviving Corporation may at or prior to the Effective Time substitute therefor a single premium tail coverage with respect to D&O Insurance with an annual cost not in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement. Notwithstanding anything in this Section 5.5 to the contrary, if any Indemnified Party notifies Parent on or prior to the sixth (6th) anniversary of the Effective Time of a matter in respect of which such Person may seek indemnification pursuant to this Section 5.5 , the provisions of this Section 5.5 that require the Surviving Corporation to indemnify and advance expenses shall continue in effect with respect to such matter until the final disposition of all claims, actions, investigations, suits and proceedings relating thereto. In the event Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 5.5 . The rights and obligations under this Section 5.5 shall survive consummation of the Merger and, following the Effective Time, shall not be terminated or amended in a manner that is adverse to any Indemnified Party without the written consent of such Indemnified Party. The provisions of this Section 5.5 are intended to be, following the Effective Time, for the benefit of, and shall be Enforceable by, each Indemnified Party, his or her heirs and his or her legal representatives.

Section 5.6 Takeover Statutes . The Parties shall, to the extent permitted by applicable Law, use reasonable best efforts to (a) take all action necessary so that no Takeover Statute or, in

44

the case of the Company, any similar provision of the Company Governing Documents, is or becomes applicable to the Merger or any of the other Transactions and (b) if any such Takeover Statute or, in the case of the Company, any similar provision of the Company Governing Documents, is or becomes applicable to any of the foregoing, to take all action necessary so that the Merger and the other Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to eliminate or minimize the effect of such Takeover Statute on the Merger and the other Transactions.

(a) Parent shall, or shall cause the Surviving Corporation to, assume, honor and fulfill all Company Benefit Plans and agreements between the Company or any Company Subsidiary, on the one hand, and any current or former employee, director or consultant, on the other hand, in accordance with their terms as in effect immediately prior to the date of this Agreement or as entered into or amended after the date of this Agreement as specifically permitted or required by this Agreement (excluding, for the avoidance of doubt, the Company Equity Plans and ESPP). For a period of one (1) year following the Effective Time, Parent shall provide, or cause to be provided, to those employees of the Company or any Company Subsidiary who continue to be employed by Parent or the Surviving Corporation or any of their respective Subsidiaries following the Effective Time, during their period of active employment by the Surviving Corporation (or any affiliate thereof) during such one (1) year period (the “ Continuing Employees ”) (i) (x) base salary (or wages) and (y) annual cash bonus opportunities that, in each case, are not less favorable than those provided by the Company immediately prior to the Effective Time and (ii) employee benefits (excluding equity or equity-based compensation) that, in the aggregate, are substantially comparable to those provided by the Company immediately prior to the Effective Time.

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

(c) Parent agrees that all Continuing Employees shall be immediately eligible to continue to participate in the Surviving Corporation’s health and welfare benefit plans (to the same extent such Continuing Employees were eligible to participate under the Company’s health

45

and welfare benefit plans immediately prior to the Effective Time); provided , however , that (i) nothing in this Section 5.8 or elsewhere in this Agreement shall limit the right of Parent or the Surviving Corporation to amend or terminate any such health or welfare benefit plan or migrate the Continuing Employees to a successor health or welfare benefit plan at any time (subject to compliance with Section 5.8(a) ) and (ii) if Parent or the Surviving Corporation terminates any such health or welfare benefit plan or migrates the Continuing Employees to a successor health or welfare benefit plan, then the Continuing Employees shall be immediately eligible to participate in the Surviving Corporation’s health and welfare benefit plans for similarly situated employees to the extent that coverage under such plans is replacing comparable coverage under a health and welfare benefit plan in which such Continuing Employee participated immediately before the Effective Time. To the extent that service is relevant for eligibility, vesting or allowances (including paid time off) under any employee benefit plan, program or arrangement of Parent or any of its affiliates, then Parent shall use its reasonable best efforts to (i) waive all limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Continuing Employees, to the extent that such conditions, exclusions and waiting periods would not apply under a similar employee benefit plan in which such employees participated immediately prior to the Effective Time, (ii) ensure that any new health or welfare benefit plan shall, for purposes of eligibility, deductibles, co-payments and out-of-pocket maximums and allowances (including paid time off), credit Continuing Employees for service and amounts paid immediately prior to the commencement of participation in such new health or welfare benefit plan to the same extent that such service and amounts paid were recognized prior to such commencement of participation under the corresponding health or welfare benefit plan of the Company, and (iii) cause service rendered to the Company and the Company Subsidiaries (or any predecessor) to be credited to the same extent as such service was recognized under a similar employee benefit plan in which such employees participated immediately prior to the Effective Time.

(d) At the request of Parent made at least ten (10) Business Days prior to the Closing Date, the Company Board (or the appropriate committee thereof) shall adopt resolutions and take such corporate action as is necessary to terminate any 401(k) plans maintained by the Company or any of its Subsidiaries (collectively, the “ Company 401(k) Plans ”), effective as of the day prior to the Closing Date and contingent upon the consummation of the Merger. The Company shall provide Parent with a reasonable opportunity to review and comment on such resolutions and any documents prepared in connection with such corporate actions prior to the adoption of such resolutions or taking of such actions. Following the Effective Time and as soon as practicable following the termination of the Company 401(k) Plans, the assets thereof shall be distributed to the participants. Parent or the Surviving Corporation shall permit the Continuing Employees who are then actively employed to make rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code), including loans, in the form of cash or promissory notes, in an amount equal to the full account balance (including loans) distributed to such Continuing Employees from the Company 401(k) Plans to Parent’s or the Surviving Corporation’s applicable 401(k) plan.

(e) Nothing in this Section 5.8 or elsewhere in this Agreement shall confer upon any Continuing Employee any right to continue in the employ or service of Parent, the Surviving Corporation or any affiliate of Parent, or shall interfere with or restrict in any way the rights of Parent, the Surviving Corporation or any affiliate of Parent, which rights are hereby expressly

46

reserved, to discharge or terminate the services of any Continuing Employee at any time for any reason whatsoever, with or without cause, except to the extent expressly provided otherwise in a written agreement between Parent, the Surviving Corporation, the Company or any affiliate of Parent and the Continuing Employee or any severance, benefit or other applicable plan or program covering such Continuing Employee. Notwithstanding any provision in this Agreement to the contrary, nothing in this Section 5.8 shall (i) be deemed or construed to be an amendment or other modification of any Company Benefit Plan or employee benefit plan of Parent or Merger Sub, (ii) create any third party rights in any Person or (iii) alter or limit the ability of the Surviving Corporation, Parent or any of their respective affiliates to amend, modify or terminate any Company Benefit Plan or other employee benefit program, agreement or arrangement at any time assumed, established, sponsored or maintained by any of them.

(f) The provisions of this Section 5.8 are solely for the benefit of the Parties to this Agreement and no current or former employee or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of the Agreement or have the right to enforce the provisions hereof.

(g) The Company shall provide Parent with a copy of any material written communications intended for broad-based and general distribution to any current or former employees of the Company or any Company Subsidiary if such communications relate to any of the Transactions, and, to the extent practicable, shall provide Parent with a reasonable opportunity to review and comment on such communications prior to distribution; provided that the Company may make written communications to current or former employees without Parent’s prior review to the extent such communications are consistent with previous press releases, public disclosures or public statements made by Parent or the Company in compliance with Section 5.4 (so long as such disclosure is still accurate).

Section 5.9 Security Holder Litigation . Each Party shall provide the other Party prompt oral notice (but in any event within two (2) Business Days) of any litigation brought or threatened by any stockholder of that Party against such Party, any of its Subsidiaries or any of their respective directors or officers relating to the Merger, this Agreement or any of the Transactions. The Company shall give Parent the opportunity to participate (at Parent’s expense) in the defense, prosecution or settlement of any such litigation, and the Company shall not offer to settle any such litigation, nor shall any such settlement be agreed to without Parent’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned; provided that the Company shall be permitted to settle any such litigation without Parent’s consent to the extent such settlement only requires the Company to provide additional disclosure. In the event of, and to the extent of, any conflict or overlap between the provisions of this Section 5.9 and Section 4.1 or Section 5.3 , the provisions of this Section 5.9 shall control.

If the Company or Parent terminates this Agreement pursuant to (i)  Section 7.1(d) or (ii) Section 7.1(b) (to the extent that such restraint arises under any antitrust Laws), and in the case of (i) or (ii), all of the conditions under Section 6.1(a) , Section 6.1(b) (except to the extent that such restraint arises under any antitrust Laws) and Section 6.2 have been satisfied or waived, other than any such conditions which by their nature cannot be satisfied until the Closing Date so long as such conditions could be satisfied if the Closing Date were the date of termination of this Agreement, then Parent shall pay or cause to be paid to the Company a fee of $100.0 million by wire transfer of same-day funds no later than five (5) Business Days after such termination (the “Reverse Termination Fee”). In the event that the Company or its designee shall receive full payment pursuant to this Section 7.2(c) , the receipt of the Reverse Termination Fee shall be the Company’s sole and exclusive remedy under this Agreement and shall be deemed to be liquidated damages for any and all losses or damages suffered or incurred by the Company, any of its affiliates or any other Person in connection with this Agreement (and the termination hereof), the Transactions (and the abandonment thereof) or any matter forming the basis for such termination, and none of the Company or any of its

53

affiliates or any other Person shall be entitled to bring or maintain any claim, action or proceeding against Parent or any of its affiliates arising out of or in connection with this Agreement, any of the Transactions or any matters forming the basis for such termination; provided that the foregoing limitation shall not apply in the event of any losses or damages incurred or suffered by the Company or any of its affiliates in the case of breach of this Agreement by Parent, Merger Sub or any of their affiliates involving fraud or a Willful Breach; provided that nothing in this Section 7.2(c) shall limit any rights, obligations or remedies that any Party may have under the Confidentiality Agreement for matters arising before or after the termination of this Agreement.

(d) Each of the Parties acknowledges that the agreements contained in this Section 7.2 are an integral part of the Transactions and that neither of the Termination Fee nor the Reverse Termination Fee is a penalty, but rather each is a reasonable amount that shall compensate Parent and Merger Sub, in the case of the Termination Fee, or the Company, in the case of the Reverse Termination Fee, in the circumstances in which such payment is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions, which amount would otherwise be impossible to calculate with precision.
