THE MERGER

1.1 The Merger. Subject to and in accordance with the terms and conditions set forth in this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company, which shall be the surviving corporation (the “Surviving Corporation”) in the Merger, and the separate existence of Merger Sub shall thereupon cease.

-1-

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger and the applicable provisions of the Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Certificate of Incorporation; Bylaws.

(a) At the Effective Time, the Certificate of Incorporation of the Company, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation until duly amended as provided by the Delaware Law and such Certificate of Incorporation; provided that as of the Effective Time, the Company’s Certificate of Incorporation shall be amended as set forth in Exhibit A to the Certificate of Merger.

(b) At the Effective Time, the Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until duly amended as provided by the Delaware Law and such Bylaws.

1.5 Directors and Officers. The parties hereto shall take all actions necessary so that, at the Effective Time, (a) the directors of Merger Sub, serving in such capacity immediately prior to the Effective Time, shall be the directors of the Surviving Corporation and (b) the officers of the Company, holding office immediately prior to the Effective Time, shall be the officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and the Bylaws of the Surviving Corporation.

1.6 Effect on Capital Stock.

(a) Conversion of Company Common Stock. By virtue of the Merger and without any further action on the part of Parent, the Company, Merger Sub or the holders of any of the Company’s securities, at the Effective Time, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time, but excluding any shares canceled pursuant to Section 1.6(b) and any Dissenting Shares, will be automatically canceled, extinguished and converted into the right to receive the Per Share Common Stock Consideration, without interest.

(b) Cancellation of Company Capital Stock Owned by the Company, Parent and Subsidiaries. At the Effective Time, all shares of Company Capital Stock that are owned by the Company as treasury stock (including any Company Preferred Stock) and each share of Company Capital Stock owned by any direct or indirect wholly owned subsidiary of the Company shall be canceled and extinguished without any rights to conversion thereof and no consideration shall be delivered in exchange therefore. At the Effective Time, any shares of

-2-

Company Capital Stock that are owned by Parent, Merger Sub or any other wholly owned subsidiary of Parent shall be canceled and retired and extinguished without any conversion thereof and no consideration shall be delivered in exchange therefor.

(c) Treatment of Company Options.

(i) Accelerated Vesting. Any outstanding, unexercised and unexpired Company Option that, by its terms, is not vested and exercisable by the holder thereof immediately prior to the Effective Time shall be accelerated in full so that each such Company Option is fully vested and exercisable as of the date thirty (30) days prior to the Effective Time. Such accelerated vesting shall be conditioned upon the consummation of the transactions contemplated in this Agreement.

(ii) Exercise or Cash Out. Any outstanding, unexercised and unexpired Company Option that is vested (either by its terms or as a result of the accelerated vesting provided pursuant to Section 1.6(c)(i) hereof) prior to the Effective Time may be exercised in full for shares of Company Common Stock prior to the Effective Time. At the Effective Time, shares of Company Common Stock purchased upon such an exercise will be automatically canceled, extinguished, and converted into the right to receive the Per Share Common Stock Consideration, without interest and less all applicable deductions and withholdings required by Law to be withheld in respect of such payment. In addition, holders of any outstanding, unexercised, and unexpired Company Options that are vested (either by their terms or as a result of the accelerated vesting provided pursuant to Section 1.6(c)(i) hereof) prior to the Effective Time shall be given an opportunity, prior to the Effective Time, to elect, instead of exercising such Company Options, to have each such Company Option canceled and converted into the right to receive an amount in cash, without interest and less all applicable deductions and withholdings required by Law to be withheld in respect of such amount, equal to the product of (x) the excess, if any, of the Per Share Common Stock Consideration over the applicable exercise price of such Company Option (it being understood and agreed that such exercise price shall not actually be paid to the Company by the holder), multiplied by (y) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time. Parent shall, or shall cause the Surviving Corporation to, pay promptly the amounts contemplated by this Section 1.6(c) following the Effective Time. Parent shall cause the Surviving Corporation to pay any amounts withheld for withholding Taxes promptly to the appropriate Governmental Entity. The exercise of any Company Option the vesting and exercisability of which is accelerated pursuant to Section 1.6(c)(i) above and the cash out of any Company Option pursuant to this Section 1.6(c)(ii) shall be conditioned upon the consummation of the transactions contemplated in this Agreement. Any and all Company Options that are not exercised or cashed out immediately prior to the Effective Time shall terminate and cease to be outstanding effective as of the Effective Time.

(iii) Further Actions. Prior to the Effective Time, the Company shall provide notice (subject to reasonable review by Parent) to each holder of Company Options describing the treatment of such Company Options in accordance with this Section 1.6(c). The Company shall take all appropriate steps to effect the termination of the Company Stock Option Plans as of the Effective Time. In addition, prior to the Effective Time, the Company shall obtain, in a manner approved by Parent, all necessary consents (if any) to give effect to the

-3-

treatment of Company Options as contemplated by this Section 1.6(c) to the extent that such treatment is not expressly provided for by the terms of the applicable Company Stock Option Plan or related award agreements.

(d) Restricted Stock Units.

(i) Cash-Out of Restricted Stock Units. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of a Restricted Stock Unit Award, each Restricted Stock Unit Award outstanding immediately prior to the Effective Time shall accelerate and shall be canceled at the Effective Time (each, a “Cashed-Out Restricted Stock Unit Award”), and each holder of a Cashed-Out Restricted Stock Unit Award shall become eligible to receive an amount in cash (without interest) equal to (A) the Per Share Common Stock Consideration multiplied by (B) the number of shares of Company Common Stock subject to each Cashed-Out Restricted Stock Unit, less all applicable deductions and withholdings required by Law to be withheld in respect of such payment. Parent shall, or shall cause the Surviving Corporation to, promptly pay to each holder of a Cashed-Out Restricted Stock Unit Award the amounts contemplated by this Section 1.6(d) following the Effective Time. Parent shall cause the Surviving Corporation to pay any amounts withheld for withholding Taxes promptly to the appropriate Governmental Entity on behalf of such holder of a Cashed-Out Restricted Stock Unit Award.

(ii) Further Actions. Prior to the Effective Time, the Company shall provide notice (subject to reasonable review by Parent) to each holder of a Restricted Stock Unit Award describing the treatment of such Restricted Stock Unit Awards in accordance with this Section 1.6(d). In addition, prior to the Effective Time, the Company shall obtain, in a manner approved by Parent, all necessary consents (if any) to give effect to the treatment of Restricted Stock Unit Awards as contemplated by this Section 1.6(d) to the extent that such treatment is not expressly provided for by the terms of the applicable Company Stock Option Plan or related award agreements.

(e) Adjustments to Per Share Common Stock Consideration. The Per Share Common Stock Consideration shall only be adjusted to reflect fully the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Capital Stock), reclassification, reorganization, recapitalization or other like change with respect to Company Common Stock occurring after the Execution Date and prior to the Effective Time, so as to provide holders of Company Common Stock the same economic effect, in the aggregate, as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reclassification, reorganization, recapitalization or like change.

(f) Capital Stock of Merger Sub. At the Effective Time, each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall continue to evidence ownership of such shares of capital stock of the Surviving Corporation.

-4-

1.7 Surrender of Certificates.

(a) Paying Agent. Computershare Investor Services LLC or another bank or trust company designated by Parent and reasonably acceptable to the Company shall act as the paying agent (the “Paying Agent”) in the Merger.

(b) Parent to Provide Cash. At or promptly following the Effective Time, Parent shall deposit with the Paying Agent for exchange in accordance with this Article I, cash in an amount sufficient to permit payment pursuant to Section 1.6(a) in exchange for shares of Company Capital Stock outstanding immediately prior to the Effective Time, less any amounts required to be withheld from such cash under any applicable Laws. All interest or other amounts earned with respect to funds made available to the Paying Agent shall be for the account of Parent.

(c) Exchange Procedures.

(i) As soon as reasonably practicable (and in any event within 5 business days) after the Effective Time, Parent shall cause to be mailed to each holder of record of a certificate or certificates (each, a “Certificate”) that immediately prior to the Effective Time represented outstanding shares of Company Capital Stock, whose shares were converted into the right to receive cash pursuant to Section 1.6(a), (1) a letter of transmittal in customary form as Parent may reasonably specify prior to the Closing (which letter shall (x) be provided to the Company for review a reasonable period prior to the Effective Time, (y) include any comments reasonably submitted by the Company and (z) specify that delivery shall be effected, and risk of loss and title to a Certificate shall pass, only upon receipt of such Certificate by the Paying Agent), and (2) instructions for use in effecting the surrender of the Certificates in exchange for cash.

(ii) Upon surrender of a Certificate to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor a cash payment pursuant to Section 1.6(a), without interest. In the event of a transfer of ownership of shares of Company Capital Stock that is not registered in the transfer records of the Company, payment pursuant to Section 1.6(a) may be made to such a transferee if the Certificate formerly representing such Shares is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and to evidence to the reasonable satisfaction of the Surviving Corporation that any applicable stock transfer Taxes have been paid or are not applicable.

(iii) In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of such fact by a stockholder of the Company (a “Company Stockholder”) claiming such Certificate to be lost, stolen or destroyed, the Paying Agent will pay such Company Stockholder in exchange for such lost, stolen or destroyed Certificate, that amount of cash that such Company Stockholder shall be entitled to receive pursuant to Section 1.6(a). When authorizing such payment in exchange therefor, the Paying Agent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to give the Paying Agent a reasonable form of

-5-

bond as indemnity, as it shall direct in accordance with (and amounts prescribed by) its customary practices, policies and procedures, against any claim that may be made against the Paying Agent with respect to the Certificate alleged to have been lost, stolen or destroyed. As a further condition to payment with respect to any Certificate that shall have been lost, stolen or destroyed, Parent may require such Company Stockholder to whom payment is to be made to agree in writing to indemnify and hold harmless Parent with respect to any loss or expense incurred by Parent as a result of the loss, theft or destruction of such Certificate.

(d) Payments with Respect to Unsurrendered Company Capital Stock. At any time following the 270th day after the Effective Time, Parent 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 Company Capital Stock (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 to Parent (subject to abandoned property, escheat and other similar laws) only as general creditors thereof with respect to any portion of the merger consideration that may be payable upon due surrender of the Certificates held by them.

(e) No Liability. Notwithstanding anything to the contrary contained in this Section 1.7, none of the Paying Agent, Parent, the Surviving Corporation or any other party hereto shall be liable to any Person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law.

1.8 No Further Ownership Rights in Company Capital Stock. After the Effective Time there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Capital Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be exchanged and canceled as provided in this Article I. Until Certificates representing shares of Company Capital Stock that are outstanding immediately prior to the Effective Time are surrendered pursuant to Section 1.7, such Certificates will be deemed, for all purposes, to evidence only ownership of the right to receive cash in the amounts determined in accordance with Section 1.6(a).

1.9 Withholding Rights. Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement such amounts as Parent and the Surviving Corporation are required to deduct and withhold with respect to such delivery and payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of any applicable Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be paid over to the appropriate Governmental Entity as required by applicable Law and shall be treated for all purposes of this Agreement as having been delivered and paid to the holder of shares of Company Common Stock in respect of which such deduction and withholding was made by Parent and the Surviving Corporation.

1.10 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, the officers and directors of

-6-

the Company, Parent and the Surviving Corporation are fully authorized in the name of their respective corporations or otherwise to take, and will take, all such lawful and necessary action, so long as such action is not inconsistent with this Agreement.

1.11 Appraisal Rights.

(a) Notwithstanding anything in this Agreement to the contrary, each share of Company Common Stock that is issued and outstanding immediately prior to the Effective Time and that is held by a Company Stockholder who has properly demanded and perfected such Company Stockholder’s appraisal rights and demanded to be paid the fair value of such shares in accordance with Section 262 of the Delaware Law (collectively, the “Dissenting Shares”), shall not be converted into the right to receive cash pursuant to Section 1.6(a), but the holder thereof shall be entitled to such rights as are granted by the Delaware Law and the Surviving Corporation shall make all payments to the holders of such Dissenting Shares with respect to such demands in accordance with the Delaware Law; provided that if any such holder shall, prior to or after the Effective Time, have failed to perfect or shall have effectively withdrawn or lost its appraisal right under the Delaware Law, each share of Company Common Stock held by such holder shall thereupon be deemed to have been converted into, as of the Effective Time, solely the right to receive the cash pursuant to Section 1.6(a).

(b) The Company shall give Parent (i) prompt written notice of any demands received by the Company for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law that are received by the Company relating to stockholders’ rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to any demand for appraisal under the Delaware Law. The Company shall not, except with the prior written consent of Parent and Merger Sub, make any payment with respect to, settle, or offer to settle, or offer to make any payment to settle, any such demands or approve any withdrawal of any such demands.

restrictive to the other party than those contained in the Non-Disclosure Agreement and that do not prohibit the Company’s compliance with the terms hereof, and (y) the Company promptly (and in any event within 24 hours) discloses (and, if applicable, provides copies of) any such non-public information to Parent to the extent not previously provided to Parent; and (B) engage or participate in discussions or negotiations with such Person regarding such Takeover Proposal, but in the case of both clause (A) and (B) above only if and to the extent that, prior to taking any such action, (x) the Board of Directors of the Company determines in good faith after consultation with outside legal counsel that such actions are necessary to comply with the directors’ fiduciary duties under applicable Law and (y) the Board of Directors of the Company has determined in good faith (after consultation with its financial advisor and outside legal counsel) that such Takeover Proposal either constitutes a Superior Proposal or is reasonably likely to result in a Superior Proposal.

(d) Except as permitted in the following paragraph, the Company’s Board of Directors and each committee thereof shall not: (1) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify), in a manner adverse to Parent, the Company Board Recommendation, or approve, endorse or recommend, or propose to approve, endorse or recommend, any Takeover Proposal; or (2) except as expressly permitted by, and after compliance with, Section 7.1(a)(vi)(B), cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other Contract (other than a confidentiality agreement referred to in Section 4.3(b) or (c) entered into in compliance with Section 4.3(b) or (c)) relating to or intended to or that could reasonably be expected to lead to any Takeover Proposal.

Notwithstanding anything to the contrary set forth in this Agreement, prior to the time, but not after, the Requisite Stockholder Approval is obtained, the Board of Directors of the Company may, in response to a Superior Proposal made after the Execution Date that was not solicited, initiated, encouraged or facilitated in breach of this Agreement, withhold, withdraw, qualify or modify the Company Board Recommendation or approve, recommend or otherwise declare advisable such Superior Proposal; provided that the Company shall not have violated in any material respect any of the terms of this Section 4.3 or Sections 5.1 and 5.2 and that before and as a condition to taking any such action, (i) the Board of Directors of the Company determines in good faith, after consultation with outside counsel, that such action is necessary to comply with its fiduciary obligations under applicable Law, (ii) the Company notifies Parent, in writing and at least four (4) business days before doing so, of its intention to take such action, attaching to such notice the most current version of such Superior Proposal, (iii) Parent fails to make, within four (4) business days of receipt of such written notification, an offer that the Board of Directors of the Company determines, in good faith after consultation with its financial advisors, is at least as favorable to the Company Stockholders from a financial point of view as such Superior Proposal, and (iv) concurrently with taking such action, the Company terminates this Agreement pursuant to Section 7.1(a)(vi)(B) and pays to Parent the Termination Fee Amount. The Company shall make its senior executives available for discussions with Parent and otherwise shall negotiate in good faith with Parent with respect to the terms and conditions of this Agreement and the Merger during such four (4) business day period. Any material amendment to any Takeover Proposal will be deemed to be a new Takeover Proposal for purposes of this Section 4.3(d), including with respect to the notice period referred to in this Section 4.3(d).

In connection therewith, if any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging any transaction

-43-

contemplated by this Agreement as violative of any Antitrust Law, each of Parent and the Company shall cooperate and use their respective commercially reasonable efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed, or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent (each an “Order”), that is in effect and that prohibits, prevents, or restricts consummation of the Merger or any such other transactions, unless by mutual agreement Parent and the Company decide that litigation is not in their respective best interests. Each of Parent and the Company shall use their respective commercially reasonable efforts to take such action as may be required to cause the expiration of the notice periods under HSR or other Antitrust Laws with respect to such transactions as promptly as possible after the execution of this Agreement.

5.8 Employee Benefit Plans.

(a) Section 16. The Company Board of Directors shall, to the extent necessary, take appropriate action, prior to or as of the Effective Time, to approve, for purposes of Section 16(b) of the Exchange Act, the deemed disposition and cancellation of the Company Options in the Merger.

-44-

automatically exercised on the Final Purchase Date, using only those participants’ payroll deductions accumulated through the last day of the payroll period ending prior to the Execution Date. The Company ESPP will then be suspended so that on and after the Final Purchase Date no new offering periods (as defined in the Company ESPP) shall commence and no new participants shall enroll in the Company ESPP pending termination of the Company ESPP immediately prior to the Effective Time. At the Effective Time, shares of Company Common Stock purchased on the Final Purchase Date will be subject to the provisions of Section 1.6(a) of this Agreement. Parent shall cause the Surviving Corporation to pay amounts withheld for withholding Taxes, if any, promptly to the appropriate Governmental Entity. Parent shall cause the Surviving Corporation to promptly return to participants their respective accumulated payroll contributions not applied to the purchase of Company Common Stock under the Company ESPP, if any. The Company shall take all actions necessary to terminate the Company ESPP immediately prior to the Effective Time.

(c) Employee Plans.

(i) 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 who continue employment with the Surviving Corporation or its subsidiaries (the “Continuing Employees”) will, to the extent permitted by applicable Law, be provided with retirement and welfare benefits (other than equity based benefits) under employee benefit plans that are substantially similar in the aggregate to those currently provided by Parent to its similarly situated employees. Parent shall use commercially reasonable efforts to cause any employee benefit plans in which Continuing Employees become entitled to participate to take into account for purposes of eligibility and vesting thereunder, except to the extent it would result in a duplication of benefits, service by employees of the Company and its subsidiaries as if such service were with Parent, to the same extent that such service was credited under a comparable Company Plan. With respect to any “employee welfare benefit plans” (within the meaning of Section 3(1) of ERISA) maintained by Parent and in which Continuing Employees become entitled to participate on or after the Effective Time (collectively, the “Parent Welfare Plans”), subject to the consent of any applicable insurance carrier, Parent shall or shall cause its applicable subsidiaries to, use its commercially reasonable efforts to (i) waive, or cause its insurance carrier to waive, all limitations as to preexisting and at-work conditions, if any, with respect to participation and coverage requirements applicable to each such Continuing Employee under any Parent Welfare Plan, and (ii) provide credit to each such Continuing Employee for any co-payments, deductibles and out-of-pocket expenses paid by such employee under the Company Plans during the relevant plan year, up to and including the Effective Time; provided, that Parent’s obligations under this Section 5.8(c)(i) shall be contingent on the Company’s timely provision of a complete and accurate listing of such expenses incurred by the Continuing Employees from January 1, 2008 (or, if earlier, the first day of the applicable plan year or years) through the date on which their participation in the Parent Welfare Plans commences. Notwithstanding the foregoing, nothing contained in this Agreement shall (1) be treated as an amendment of any particular Company Plan, or limit in any way the ability of Parent or any of its subsidiaries or affiliates (including after the Effective Time the Surviving Corporation and its subsidiaries) to amend or terminate any particular Company Plan, (2) give any employee of the Company or any of its subsidiaries or any other third party any right to enforce the provisions of this Section 5.8 or (3) obligate Parent, the Surviving Corporation or any of their affiliates to (x) offer or maintain any particular benefit plan or type of compensation or employee benefit or (y) continue the employment of any particular employee.

-45-

(ii) Prior to the Effective Time, if requested by Parent, to the extent permitted by applicable Law and the terms of the applicable plan or arrangement, the Company shall (1) cause to be amended the employee benefit plans and arrangements of it and its subsidiaries to the extent necessary to provide that no employees of Parent and its subsidiaries shall commence participation therein following the Effective Time unless the Surviving Corporation or such subsidiary explicitly authorizes such participation and (2) cause the Company’s 401(k) Plan and any other Company Plans specified by Parent to be terminated effective immediately prior to the Effective Time. If Parent requests that any of the Company Plans be terminated, the Company shall adopt resolutions and shall take all other actions necessary to effect the termination of any such plans, to be effective immediately prior to the Effective Time, and shall provide to Parent executed resolutions by the Board of Directors of the Company authorizing the termination of any such plans.

5.9 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation and its subsidiaries to, honor and fulfill in all respects the obligations of the Company and its subsidiaries under any and all indemnification agreements disclosed in Section 2.22 of the Company Disclosure Schedule between the Company or any of its subsidiaries and any of its current or former directors and officers (the “Indemnified Parties”). In addition, for a period of six (6) years following the Effective Time, Parent shall (and shall cause the Surviving Corporation and its subsidiaries to) cause the certificate or articles of incorporation and bylaws (and other similar organizational documents) of the Surviving Corporation and its subsidiaries to contain provisions with respect to indemnification and exculpation that are at least as favorable to the beneficiaries thereof as the indemnification and exculpation provisions contained in the certificate or articles of incorporation and bylaws (or other similar organizational documents) of the Company and its subsidiaries immediately prior to the Effective Time, and, during such six-year period, such provisions shall not be amended, repealed or otherwise modified in any respect, except as required by applicable Law.

(b) For six (6) years after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, maintain in effect an officers’ and directors’ liability insurance policy (the “D&O Policy”) in respect of acts or omissions occurring on or prior to the Effective Time covering each such Person currently covered by such policy of the Company as in effect on the date hereof on terms that in the aggregate are no less favorable to such Persons than those of such policy of the Company as in effect on the date hereof, which policy may be a “tail” or “runoff” policy; provided that, in satisfying their obligations under this Section 5.9(b), Parent and Surviving Corporation shall not be obligated to pay annual premiums in excess of 150% of the Annual Premium or a premium for the tail or runoff policy in excess of 400% of the Annual Premium; provided, however, that if Parent and the Surviving Corporation would otherwise be required to expend more than 150% of the Annual Premium for an annual policy or more than 400% of the Annual Premium for such a tail or runoff policy, then they shall obtain as much comparable insurance as possible for an annual premium equal to 150% of the Annual Premium or a premium equal to 400% of the Annual Premium, as the case may be.

-46-

Notwithstanding the foregoing, prior to the Effective Time, the Company may purchase a directors’ and officers’ liability insurance tail or runoff insurance program, in form and substance reasonably satisfactory to Parent, effective as of the Effective Time, covering a period of six (6) years from and after the Effective Time with respect to acts or omissions occurring on or prior to the Effective Time; provided that the premium for such coverage shall not exceed 400% of the Annual Premium. In the event that the Company purchases such a “tail” or “runoff” policy prior to the Effective Time, Parent and the Surviving Corporation shall maintain such tail or runoff policy in full force and effect in lieu of all other obligations of Parent and the Surviving Corporation under the first sentence of this Section 5.9(b) for so long as such tail or runoff policy shall be maintained in full force and effect. The Company represents to Parent that the amount per annum the Company paid for the D&O Policy for the period from October 18, 2007 to October 18, 2008 (the “Annual Premium”) is as set forth in Section 5.9(b) of the Company Disclosure Schedule. Neither Parent or the Company shall be deemed in breach of their obligations to maintain any insurance policy pursuant to this Section 5.9(b) as to any Indemnified Party that is denied coverage under such insurance policy by the issuer or underwriter thereof as a result of any act or omission of an Indemnified Person in connection with the application for such insurance policy or any claim thereunder.

(c) Each of the Indemnified Parties or other persons who are beneficiaries under the D&O Policy or the “tail” or “runoff” policy referred to in Section 5.9(b) (and their heirs and representatives) are intended to be third party beneficiaries of this Section 5.9, with full rights of enforcement as if a party hereto. The rights of the Indemnified Parties (and other persons who are beneficiaries under the D&O Policy or the “tail” or “runoff” policy referred to in Section 5.9(b) (and their heirs and representatives)) under this Section 5.9: (i) shall be in addition to, and not in substitution for, any other rights that such persons may have under the certificate or articles of incorporation, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Company or any of its subsidiaries, or applicable Law (whether at law or in equity) and (ii) shall be binding upon all assigns of all or substantially all of the business of the Company or the Surviving Corporation and the successors of the Company and the Surviving Corporation.

5.10 Takeover Statutes. If any Takeover Statute shall become applicable to the transactions contemplated by this Agreement, the Company and the members of the Board of Directors of the Company shall grant all such approvals and use reasonable best efforts to take all such actions as are necessary so that the Merger and the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and thereby and otherwise act to eliminate or minimize the effects of such statute or regulation on such transactions.

5.11 Notices. The Company shall give all notices and other information required to be given to the employees of the Company and its subsidiaries, any collective bargaining unit representing any group of employees of the Company or any of its subsidiaries, if applicable, and any applicable Governmental Entity under the WARN Act, the National Labor Relations Act, the Code, the Consolidated Omnibus Budget Reconciliation Act, and other applicable Law in connection with the transactions provided for in this Agreement.

8.6 Severability.

The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the fullest extent possible, the economic, business and other purposes of such void or unenforceable provision.

8.7 Remedies Cumulative; Specific Performance.

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

(b) The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, the parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any Delaware state or federal court within the State of

-59-

Delaware), this being in addition to any other remedy to which such party is entitled at law or in equity. Each Party hereby waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any Law to post security as a prerequisite to obtaining equitable relief.

8.8 Governing Law; Jurisdiction and Venue; WAIVER OF JURY TRIAL. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware without reference to such state’s principles of conflicts of Law. Each of the parties hereto irrevocably (x) consents to the exclusive jurisdiction of any state court located within the State of Delaware in connection with any matter based upon or arising out of this Agreement or the matters contemplated herein and agrees that no action, suit or proceeding in connection therewith shall be brought by it or any of its subsidiaries in any other courts, (y) agrees that process may be served upon them in any manner authorized by the Laws of the State of Delaware for such Persons and (z) waives and covenants not to assert or plead any objection that such party might otherwise have to such jurisdiction and such process, including any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. THE PARTIES HERETO IRREVOCABLY WAIVE THE RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY ACTIONS, SUITS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE MERGER OR THE TRANSACTIONS CONTEMPLATED HEREBY.

8.9 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

8.10 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of the other party, and any attempt to make any such assignment without such consent shall be null and void, provided, that Parent and Merger Sub may assign any or all of their respective rights, interests and obligations to Parent or any affiliate of Parent, but no such assignment shall relieve Parent or Merger Sub of its obligations hereunder. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

8.11 Attorneys’ Fees. In any action at law or suit in equity to enforce this Agreement or the rights of any of the parties hereunder, the prevailing party in such action or suit shall be entitled to receive a sum for its attorneys’ fees and all other costs and expenses incurred in such action or suit.
