WHEREAS, certain executives of the Company have executed and delivered to Parent a Consulting Agreement and Restrictive Covenant Agreement in substantially the forms attached hereto as Exhibits C and D, respectively, as a further inducement to Parent to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement and intending to be legally bound hereby, the parties hereto agree as follows:

Article I

The Merger

Section 1.1 The Merger. Upon the terms and subject to satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the DGCL, Merger Sub, at the Effective Time, shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation of the Merger (the “Surviving Corporation”) and shall be a wholly owned subsidiary of Parent.

Section 1.2 Closing. The closing of the Merger (the “Closing”) shall take place as promptly as practicable, but in no event later than the first business day after the satisfaction or waiver of the conditions (excluding conditions that, by their nature, cannot be satisfied until the Closing Date) set forth in Article VI, unless this Agreement has been theretofore terminated pursuant to its terms or unless another time or date is agreed to in writing by the parties hereto (the actual date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, unless another place is agreed to in writing by the parties hereto. As soon as practicable on or after the Closing Date, the parties hereto shall cause the Merger to be consummated by filing a certificate of merger relating to the Merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with the relevant provisions of, the DGCL (the date and time of such filing, or if another date and time is agreed to in writing by the parties hereto and is specified in such filing, such specified date and time, being the “Effective Time”).

Section 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, at the Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers and franchises of Merger Sub and the Company shall vest in the Surviving Corporation, and all debts, liabilities and duties of Merger Sub and the Company shall become the debts, liabilities and duties of the Surviving Corporation.

Section 1.4 Certificate of Incorporation; Bylaws. At the Effective Time, (a) the Certificate of Incorporation of the Surviving Corporation shall be amended in its entirety to contain the provisions set forth in the Certificate of Incorporation of Merger Sub and (b) the Bylaws of the Surviving Corporation shall be amended in their entirety to contain the provisions set forth in the Bylaws of Merger Sub, each as in effect immediately prior to the Effective Time, and in each case until thereafter changed or amended as provided therein or pursuant to applicable Law.

Section 1.5 Directors and Officers of Surviving Corporation. At the Effective Time, the initial directors of the Surviving Corporation shall be the directors of Merger Sub, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation. The initial officers of the Surviving Corporation shall be the officers of Merger Sub, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation.

Article II

Conversion of Securities; Exchange of Certificates

Section 2.1 Conversion of Securities. 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 any of the following securities:

(a) Conversion Generally. Each share of common stock, par value $.001 per share, of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than any shares of Company Common Stock to be canceled pursuant

to Section 2.1(b)), shall be converted, subject to Section 2.2(e), into the right to receive 1.0972 shares (the “Exchange Ratio”) of common stock, par value $.001 per share, of Parent (“Parent Common Stock”). All such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent the right to receive a certificate representing the shares of Parent Common Stock into which such Company Common Stock was converted in the Merger. Certificates previously representing shares of Company Common Stock shall be exchanged for certificates representing whole shares of Parent Common Stock issued in consideration therefor upon the surrender of such certificates in accordance with the provisions of Section 2.2, without interest. No fractional share of Parent Common Stock shall be issued, and in lieu thereof, a cash payment shall be made pursuant to Section 2.2(e) hereof.

(b) Cancellation of Certain Shares. Each share of Company Common Stock held by Parent, Merger Sub, any wholly-owned subsidiary of Parent or Merger Sub, in the treasury of the Company or by any wholly-owned subsidiary of the Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no payment shall be made with respect thereto.

(c) Merger Sub. Each share of common stock, par value $.001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and be exchanged for one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

(d) Change in Shares. If between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or other similar event or transaction, the Exchange Ratio shall be equitably adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or other similar event or transaction.

Section 2.2 Exchange of Certificates.

(a) Exchange Agent. As of the Effective Time, Parent shall irrevocably deposit, or shall cause to be deposited, with Computershare Trust Company or another bank or trust company mutually agreeable to Parent and the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article II through the Exchange Agent, certificates representing the shares of Parent Common Stock issuable pursuant to Section 2.1 and cash in an amount sufficient to permit payment of cash in lieu of fractional shares pursuant to Section 2.2(e) (such certificates for shares of Parent Common Stock, together with cash in lieu of fractional shares and any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”) in exchange for outstanding shares of Company Common Stock. The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Parent Common Stock contemplated to be issued pursuant to Section 2.1 and the cash contemplated to be issued pursuant to Section 2.2(e) out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time, Parent shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Certificates”) (i) a letter of transmittal reasonably acceptable to the Company (which 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 to the Exchange Agent and shall be in reasonable and customary form) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Parent Common Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, properly completed and duly executed, and such other documents as may be reasonably required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Parent Common Stock which such holder has the right to receive in respect of the shares of Company Common Stock formerly represented by such Certificate (after taking into account all shares of Company Common Stock then held by such holder), cash in lieu of fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c), and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on any cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Common Stock which is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Parent Common Stock may be issued to a transferee if the Certificate representing such shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents reasonably required to evidence and effect such transfer and by evidence reasonably satisfactory that any applicable stock transfer taxes, if any, have been paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of Parent Common Stock, cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c).

(c) Distributions with Respect to Unexchanged Shares of Parent Common Stock. No dividends or other distributions declared or made after the Effective Time with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e), unless and until the holder of such Certificate shall surrender such Certificate. Subject to the effect of escheat, tax or other applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) promptly, the amount of any cash payable with respect to a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole shares of Parent Common Stock.

(d) Further Rights in Company Common Stock. All shares of Parent Common Stock issued upon conversion of the shares of Company Common Stock in accordance with the terms hereof (including any cash paid pursuant to Section 2.2(c) or Section 2.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock.

(e) Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share and such fractional share interests will not entitle the owner thereof to any rights of a stockholder of Parent. In lieu of any fractional shares of Parent Common Stock that would otherwise be issued, each stockholder that would have been entitled to receive a fractional share of Parent Common Stock shall, upon proper surrender of the Certificates, receive a cash payment equal to such fraction multiplied by the average closing price of one share of Parent Common Stock as reported on the Exchange for the five (5) trading days ending on and including the second trading day preceding the Effective Time.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for nine (9) months after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Common Stock who have not theretofore complied with this Article II shall thereafter look only to Parent for the shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock to which they are entitled pursuant to Section 2.2(e) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant to Section 2.2(c), in each case, without any interest thereon.

(g) No Liability. None of Parent, the Surviving Corporation or the Company shall be liable to any holder of shares of Company Common Stock for any such shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Parent, the posting by such person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.2(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.2(c), in each case, without any interest thereon.

(i) Withholding. Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as Parent or the Exchange Agent is required to deduct and withhold under applicable Law with respect to the making of such payment. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company

Common Stock in respect of whom such deduction and withholding was made by Parent or the Exchange Agent.

Section 2.3 Appraisal Rights. Pursuant to Section 262(b) of the DGCL, the holders of shares of Company Common Stock shall not be entitled to appraisal rights as a result of the Merger.

Section 2.4 Stock Options. Prior to the Effective Time, the Board of Directors of the Company (the “Company Board”) (or, if appropriate, any committee thereof) shall take all actions necessary and appropriate to provide that, at the Effective Time, all unexercised and unexpired options to purchase Company Common Stock (“Company Options”) then outstanding, under any stock option plan of the Company or any other plan, agreement or arrangement (the “Company Stock Option Plans”), whether or not then exercisable, shall be assumed by Parent and, as so assumed, shall continue to have, and be subject to, the same terms and conditions (including vesting schedule) as set forth in the Company Stock Option Plan and any agreements thereunder immediately prior to the Effective Time, except that (a) each Company Option shall be exercisable (or shall become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock that were issuable upon exercise of such Company Option immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock, (b) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Option shall be equal to the quotient determined by dividing the exercise price per share of Company Common Stock at which such Company Option was exercisable immediately prior to the Effective Time by the Exchange Ratio, rounded up to the nearest whole cent, and (c) such assumed Company Option will be eligible to participate in any “cashless exercise” or “same day sale” program to the extent made available to the holders of Parent Options and to the extent consistent with the terms of the Company Option agreements. The conversion of any Company Options into options to purchase Parent Common Stock shall be made so as not to constitute a “modification” of such Company Options within the meaning of Sections 409A and 424 of the Code. As of the Effective Time, Parent shall amend the Company Stock Option Plans to allow Parent to grant awards under the terms of the Company Stock Option Plans (including the right to grant incentive stock options) with respect to Parent Common Stock after the Effective Time equal to the product of (i) the sum of (A) the number of shares of Company Common Stock authorized for issuance under the Company Stock Option Plans less (B) shares of Company Common Stock issued under the Company Stock Option Plans prior to the Effective Time, less (C) shares of Company Common Stock subject to outstanding Company Options, multiplied by (ii) the Exchange Ratio; provided, however, such awards shall be made solely to employees of the Company.

Section 2.5 Employee Stock Purchase Plan. Prior to the Effective Time, the Company Board shall take all actions with respect to the Company Employee Stock Purchase Plan (the “ESPP”), including, if appropriate, amending the terms of the ESPP, that are necessary to (a) cause the ending date of the Offering under the ESPP (as such term is defined therein) that is in effect as of the date of this Agreement to occur on or before the last trading day prior to the Effective Time, if the Effective Time is prior to the end of such Offering, (b) cause all existing Offerings under the ESPP to terminate immediately following the purchase on the earlier of the last trading day prior to the Effective Time or the ending date of the Offering that is in effect as

of the date of this Agreement (such earlier date, the “Final Purchase Date”), (c) suspend all future Offerings that would otherwise commence under the ESPP following the Final Purchase Date and (d) cease all further payroll deductions under the ESPP effective as of the Final Purchase Date. On the Final Purchase Date, the Company shall apply the funds credited as of such date under the ESPP within each participant’s payroll withholding account to the purchase of whole shares of Company Common Stock in accordance with the terms of the ESPP, which shares shall be treated in the manner described in Section 2.1.

Section 2.6 Warrants. Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof) shall take all actions necessary and appropriate to provide that, at the Effective Time, each warrant to purchase shares of Company Common Stock (a “Company Warrant”) then outstanding shall, in accordance with the terms thereof, cease to represent a right to acquire shares of Company Common Stock and automatically shall be converted, at the Effective Time, without any action on the part of the holder thereof, into a warrant to purchase shares of Parent Common Stock (as so converted, a “Company Converted Warrant”) and, as so converted, shall continue to have, and be subject to, the same terms and conditions as set forth in any agreements thereunder immediately prior to the Effective Time, except that, as of the Effective Time, (a) each Company Converted Warrant shall be exercisable (or shall become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares that were issuable upon exercise of such Company Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock, and (b) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such Company Converted Warrant shall be equal to the quotient determined by dividing the exercise price per share of Company Common Stock at which such Company Warrant was exercisable immediately prior to the Effective Time by the Exchange Ratio, rounded to the nearest whole cent.

Section 2.7 Restricted Stock. Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof) shall take all actions necessary and appropriate to provide that, if any shares of Company Common Stock that are outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition providing that such shares may be forfeited or repurchased upon any termination of the stockholders’ employment, directorship or other relationship with the Company (and/or any Subsidiary of the Company), under the terms of any agreement with the Company (and/or any Subsidiary of the Company) that does not by its terms provide that such repurchase option, risk of forfeiture or other condition lapses upon consummation of the Merger, then the shares of Parent Common Stock issued upon the conversion of such shares in the Merger shall continue to be unvested and subject to the same repurchase options, risks of forfeiture or other conditions following the Effective Time, and the certificates representing such shares of Parent Common Stock may accordingly be marked with appropriate legends noting such repurchase options, risks of forfeiture or other conditions.

Article III

Representations and Warranties of the Company

Except as set forth in a disclosure memorandum delivered by the Company to Parent prior to the execution of this Agreement (the “Company Disclosure Memorandum”), which identifies exceptions by specific Section references (provided, that any matter disclosed in any section of the Company Disclosure Memorandum shall be considered disclosed for other sections of the Company Disclosure Memorandum, but only to the extent such matter on its face would be reasonably expected to be pertinent to a particular section of the Company Disclosure Memorandum in light of the disclosure made in such section), the Company hereby represents and warrants to Parent as follows:

Section 3.1 Organization and Qualification; Subsidiaries. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. Each Subsidiary of the Company has been duly organized, and is validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization, as the case may be. The Company and each of its Subsidiaries has the requisite power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except for such powers, authorities and approvals that would not, individually or in the aggregate, have a Material Adverse Effect. The Company and each of its Subsidiaries is duly qualified or licensed to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification, licensing or good standing necessary, except for such failures to be so qualified, licensed or in good standing that would not, individually or in the aggregate, have a Material Adverse Effect. Section 3.1 of the Company Disclosure Memorandum sets forth a true and complete list of all of the Subsidiaries of the Company. Except as set forth in Section 3.1 of the Company Disclosure Memorandum and shares of other Subsidiaries, none of the Company or any of its Subsidiaries holds an Equity Interest in any other person.

Section 3.2 Certificate of Incorporation and Bylaws; Corporate Books and Records. The copies of the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Company Certificate”), and Amended and Restated Bylaws, as amended (the “Company Bylaws”), that are listed as exhibits to the Company’s Form 10-K filed with the SEC for the fiscal year ended December 31, 2004 (the “2004 Form 10-K”) are complete and correct copies thereof as in effect on the date hereof. The Company is not in violation of any of the provisions of the Company Certificate or the Company Bylaws. True and complete copies of all minute books of the Company have been made available by the Company to Parent.

Section 3.3 Capitalization.

(a) The authorized capital stock of the Company consists of 80,000,000 shares of Company Common Stock and 5,000,000 shares of preferred stock, par value $.001 per share, of the Company (“Company Preferred Stock”). As of July 5, 2005, (i) 46,876,088 shares of Company Common Stock (other than treasury shares) were issued and outstanding, all of which were validly issued and fully paid, nonassessable and free of preemptive rights, (ii) no shares of Company Common Stock were held in the treasury of the Company or by its Subsidiaries,

(iii) 14,058,641 shares of Company Common Stock were issuable (and such number was reserved for issuance) upon exercise of Company Options outstanding as of such date, and (iv) 1,008,065 shares of Company Common Stock were issuable (and such number was reserved for issuance) upon exercise of Company Warrants outstanding as of such date. As of such date, no shares of Company Preferred Stock were issued or outstanding. All capital stock or other equity securities of the Company have been issued in compliance with applicable federal and state securities laws.

(b) Except for Company Options to purchase not more than 14,058,641 shares of Company Common Stock, Company Warrants to purchase not more than 1,008,065 shares of Company Common Stock and arrangements and agreements set forth in Section 3.3 of the Company Disclosure Memorandum, there are no options, warrants or other rights, agreements, arrangements or commitments of any character to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound relating to the issued or unissued capital stock or other Equity Interests of the Company or any of its Subsidiaries, or securities convertible into or exchangeable for such capital stock or other Equity Interests, or obligating the Company or any of its Subsidiaries to issue or sell any shares of its capital stock or other Equity Interests, or securities convertible into or exchangeable for such capital stock of, or other Equity Interests in, the Company or any of its Subsidiaries. Since December 31, 2004, the Company has not issued any shares of its capital stock, or securities convertible into or exchangeable for such capital stock or other Equity Interests, other than those shares of capital stock reserved for issuance as set forth in this Section 3.3 or Section 3.3 of the Company Disclosure Memorandum. The Company has provided Parent with a true and complete list, as of the date hereof, of the prices at which outstanding Company Options may be exercised under the Company Stock Option Plans, the number of Company Options outstanding at each such price and the vesting schedule of the Company Options.

Except as required pursuant to any confidentiality agreement or similar agreement or arrangement to which the Company or Parent or any of their respective Subsidiaries is a party (which, if reasonably requested by the other party, such person shall use reasonable best efforts to cause the counterparty to waive), from the date of this Agreement to the Effective Time, the Company and Parent shall, and shall cause each of its Subsidiaries and each of their respective directors, officers, employees, accountants, consultants, legal counsel, investment bankers, advisors, and agents and other representatives (collectively, “Representatives”); provided, however, that the foregoing shall not require the Company or Parent to waive any legal privilege or disclose proprietary information relevant to the negotiation of this Agreement or the evaluation of the transactions contemplated hereby to (a) provide to the other party and its respective Representatives access at reasonable times upon reasonable prior notice to the officers, employees, agents, properties, offices and other facilities of such party and its Subsidiaries and to the books and records thereof and (b) subject to applicable Laws relating to the exchange of information, furnish promptly such information concerning the business, properties, Contracts, assets, liabilities, personnel and other aspects of itself and its Subsidiaries as the other party and its Representatives may reasonably request.

The Company shall immediately terminate, and shall cause its Subsidiaries and use its reasonable best efforts to cause its and its Subsidiaries’ Representatives to immediately terminate, all discussions or negotiations, if any, with any third party with respect to, or any that could reasonably be expected to lead to an Acquisition Proposal. The Company shall promptly (and in any event within two (2) business days) request that each person which has heretofore executed a confidentiality agreement with it or any of its Subsidiaries or any of its or its Subsidiaries’ Representatives with respect to such person’s consideration of a possible Acquisition Proposal immediately return or destroy all confidential information heretofore furnished to such person or its Representatives.

(b) Neither the Company Board nor any committee thereof shall (i) withdraw, modify or amend, or propose to withdraw, modify or amend, in a manner adverse to Parent, the Company Recommendation or (ii) resolve to do any of the foregoing; provided, that the Company Board may withdraw, modify or amend the Company Recommendation if, following

receipt of a Superior Proposal (A) the Company has complied with its obligations under this Section 5.5, (B) the Company Board reasonably determines in good faith, after consultation with its outside legal counsel (which may be its current outside legal counsel), that failure to take such actions would be inconsistent with its fiduciary duties under applicable Law and (C) prior to taking such actions, the Company Board shall have given Parent at least five (5) days notice of its intention to take such action and the opportunity to meet with the Company and its outside counsel and financial advisor.

(c) In addition to the obligations set forth in Section 5.5(a), the Company shall as promptly as practicable (and in any event within 48 hours) advise Parent of any request for information with respect to any Acquisition Proposal or of any Acquisition Proposal, or any inquiry, proposal, discussions or negotiation with respect to any Acquisition Proposal, the terms and conditions of such request, Acquisition Proposal, inquiry, proposal, discussion or negotiation, and the Company shall, within 48 hours of the receipt thereof, promptly provide to Parent copies of any written materials received in connection with any of the foregoing, and the identity of the person making any such Acquisition Proposal or such request, inquiry or proposal or with whom any discussions or negotiations are taking place. The Company shall keep Parent reasonably informed of the status and material details (including material amendments) with respect to the information previously provided by the Company in connection with the Acquisition Proposal, and shall provide to Parent within 48 hours of receipt thereof all written materials received by it with respect thereto. The Company shall promptly provide to Parent any non-public information concerning it provided to any other person in connection with any Acquisition Proposal, which was not previously provided to Parent. With respect to any Acquisition Proposal that constitutes a Superior Proposal, during the five (5) day period referred to in clause (C) of Section 5.5(b) above, the Company shall, if requested by Parent, provide Parent with an opportunity to negotiate revisions to the terms of this Agreement for the Company Board’s good faith consideration.

Such service also shall apply for purposes of satisfying any waiting periods, evidence of insurability requirements, or the application of any pre-existing condition limitations.

(b) The parties hereto acknowledge and agree that all provisions contained in this Section 5.10 with respect to employees are included for the sole benefit of the respective parties hereto and shall not create any right (i) in any other person, including, without limitation, any employees, former employees, any participant in any Company Benefit Plan or Parent Benefit Plan or any beneficiary thereof or (ii) to continued employment with the Company or Parent.

Parent shall provide or cause the Surviving Corporation to provide that if any Company Employee is terminated on or after the Effective Time, such Company Employee shall be entitled to severance equal to the greater of (i) the amount of severance such Company Employee would have been entitled to receive under the severance benefits and policies set forth in Section 3.11 of the Company Disclosure Memorandum (as amended to the extent provided above) had such Company Employee been involuntarily terminated as of the Effective Time and (ii) the amount of severance such Company Employee would be entitled to receive under the applicable severance policies and practices of Parent or its subsidiaries, as applicable, assuming (for purposes of calculating their severance entitlement hereunder) that their employment with Parent commenced as of the Effective Time.

(b) Parent shall obtain a prepaid director and officer insurance policy (the “D&O Insurance”) prior to the Effective Time, which D&O Insurance policy shall be reasonably acceptable to the Company and shall provide the Company Indemnified Persons with coverage that is no less favorable than the Company’s existing policy (a true and complete copy of which has been previously provided to Parent) for an aggregate period of six (6) years with respect to claims arising from facts or events that occurred on or before the Effective Time, including, without limitation, in respect of the transactions contemplated by this Agreement. Parent shall maintain such policy in full force and effect, and continue to honor the obligations thereunder.

(c) In the event Parent (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 provisions shall be made so that such continuing or surviving corporation or entity or transferee of such assets, as the case may be, shall assume the obligations set forth in this Section 5.11.

(d) The obligations under this Section 5.11 shall not be terminated or modified in such a manner as to adversely affect any Company Indemnified Person to whom this Section 5.11 applies or the heirs and representatives of such Company Indemnified Person

Section 7.2 Effect of Termination.

(a) Limitation on Liability. In the event of termination of this Agreement by either Parent or the Company as provided in Section 7.1, this Agreement shall forthwith become

void and there shall be no liability or obligation on the part of Parent or the Company or their respective Subsidiaries, officers or directors except (i) with respect to the confidentiality obligations of Section 5.4, Section 5.9, this Section 7.2 and Article VIII and (ii) with respect to any liabilities or damages incurred or suffered by a party as a result of the willful breach by the other party of any of its representations, warranties, covenants or other agreements set forth in this Agreement.

(b) Termination Fee. The Company shall pay Parent a termination fee of $2,000,000 (the “Termination Fee”) in immediately available funds in the event that this Agreement is terminated solely as follows: (i) if the Company shall terminate this Agreement pursuant to Section 7.1(e); (ii) if Parent shall terminate this Agreement pursuant to Section 7.1(d); or (iii) if (A) Parent shall terminate this Agreement pursuant to Section 7.1(f), or either party shall terminate this Agreement pursuant to Section 7.1(b) or 7.1(i)(1), and, at any time after the date of this Agreement and before the termination of this Agreement, an Acquisition Proposal with respect to the Company shall have been publicly made, proposed or communicated and not bona fide withdrawn and (B) within twelve (12) months following the termination of this Agreement, the Company consummates such Acquisition Proposal or enters into a binding agreement with respect to such Acquisition Proposal which is subsequently consummated. Any Termination Fee payable under this provision shall be payable as liquidated damages to compensate Parent for the damages Parent will suffer if this Agreement is terminated under the circumstances set forth in this Section 7.2(b), which damages cannot be determined with reasonable certainty. It is specifically agreed that the Termination Fee represents liquidated damages and not a penalty.

(c) All Payments. Any payment required to be made pursuant to Section 7.2(b)(i) shall be paid prior to or contemporaneously with, and shall be a pre-condition to the effectiveness of, termination of this Agreement pursuant to Section 7.1(e). Any payment required to be made pursuant to Section 7.2(b)(ii) shall be paid not later than two (2) business days after the date of termination. Any payment required to be made pursuant to Section 7.2(b)(iii) shall be paid prior to or contemporaneously with, and shall be a pre-condition to the effectiveness of, consummation of the Acquisition Proposal. All payments under this Section 7.2 shall be made by wire transfer of immediately available funds to an account designated by Parent. The Company acknowledges that the agreements contained in this Section 7.2 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, Parent would not enter into this Agreement. Accordingly, if the Company fails promptly to pay any amount due pursuant to this Section 7.2 and, in order to obtain such payment, Parent commences a suit which results in a judgment against the Company for the fee set forth in this Section 7.2, the Company shall pay to Parent its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the fee at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made.

Section 7.3 Amendment. To the extent permitted by applicable Law, this Agreement may be amended by the parties, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with the Merger by the stockholders of Parent and the Company; provided, that after any such approval, no amendment shall be made that by Law requires further approval by the Company’s or

Parent’s stockholders, as the case may be, without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

Section 7.4 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties of the other parties contained herein or in any document delivered pursuant hereto, and (c) waive compliance by the other parties with any of the agreements or conditions contained herein; provided, however, that after any approval of the transactions contemplated by this Agreement by the stockholders of any party, there may not be, without further approval of such stockholders, any extension or waiver of this Agreement or any portion thereof which, by Law or in accordance with the rules of the Exchange, requires further approval by such stockholders. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Section 7.5 Fees and Expenses. Subject to Section 7.2(a) hereof, all expenses incurred by the parties hereto shall be borne solely and entirely by the party which has incurred the same (including, but not limited to, fees and expenses of counsel, accountants, investment bankers and other advisors); provided, however, that each of Parent and the Company shall pay one-half of (a) the expenses related to printing, filing and mailing the Registration Statement and the Joint Proxy/Prospectus and all SEC and other regulatory filing fees incurred in connection with the Registration Statement and the Joint Proxy/Prospectus, and (b) the filing fees related to any filings under the HSR Act.

economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto 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 to the end that transactions contemplated hereby are fulfilled to the extent possible.

Section 8.7 Entire Agreement. This Agreement (together with the Exhibits, Parent Disclosure Memorandum and Company Disclosure Memorandum and the other documents delivered pursuant hereto) and the Confidentiality Agreement (other than the disclaimer of any representations and warranties contained therein which is superseded hereby) constitute the entire agreement of the parties and supersede all prior agreements and undertakings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof, and except as otherwise expressly provided herein, are not intended to confer upon any other person any rights or remedies hereunder.

Section 8.8 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 parties, and any attempt to make any such assignment without such consent shall be null and void.

Section 8.9 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and assigns, and nothing in this Agreement, express or implied, other than pursuant to Sections 5.11 and 5.17, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 8.10 Mutual Drafting. Each party hereto has participated in the drafting of this Agreement, which each party acknowledges is the result of extensive negotiations between the parties.

Section 8.11 Governing Law; Consent to Jurisdiction; Waiver of Trial by Jury.

(a) This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without regard to laws that may be applicable under conflicts of laws principles.

(b) Each of the parties hereto irrevocably and unconditionally (i) agrees that any suit, action or other legal proceeding arising out of or relating to this Agreement or any of the agreements delivered in connection herewith or the transactions contemplated hereby or thereby shall be brought in state courts of the State of Delaware (or, if such courts do not have jurisdiction or do not accept jurisdiction, in the United States District Court located in the State of Delaware), (ii) consents to the jurisdiction of any such court in any such suit, action or proceeding, and (iii) waives any objection that such party may have to the laying of venue of any such suit, action or proceeding in any such court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party to this

Agreement irrevocably consents to service of process in the manner provided for notices in Section 8.2. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.11(c).

Section 8.12 Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 8.13 Specific Performance. The parties hereto agree that irreparable damage could 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. It is accordingly agreed that the parties shall not object to the granting of such relief on the basis that an adequate remedy exists at law and shall not insist upon the posting of any bond as a condition to the granting of any such relief, this being in addition to any other remedy to which they are entitled at law or in equity.
