RECITALS

WHEREAS, the respective boards of directors of Parent, Purchaser and the Company have determined that it is in the best interests of each of the Parent, Purchaser and the Company, respectively, and their respective stockholders for Parent to acquire the Company on the terms and subject to the conditions set forth in this Agreement;

WHEREAS, in furtherance of the acquisition of the Company by Parent, it is proposed that such acquisition be accomplished by (a) Purchaser commencing a tender offer (the “Offer”) to acquire all of the outstanding shares (each, a “Share” and collectively, the “Shares”) of common stock, par value $0.0001 per share, of the Company (“Common Stock”), at a price of four dollars and fifteen cents ($4.15) per Share (such amount, or any different amount per Share that may be paid pursuant to the Offer in accordance with the terms hereof, being hereinafter referred to as the “Offer Price”), subject to reduction for any dividends or other distributions declared thereon between the date hereof and the Acceptance Time, net to the holders thereof in cash, without interest, on the terms and subject to the conditions set forth herein and (b) following the consummation of the Offer, the merger of the Purchaser with and into the Company, with the Company as the surviving corporation in the Merger (as defined herein), and each Share that is not tendered and accepted pursuant to the Offer shall thereupon be cancelled and converted into the right to receive cash, in an amount equal to the Offer Price, subject to reduction for any dividends or other distributions declared thereon between the date hereof and the Acceptance Time, net to the holders thereof in cash, without interest, on the terms and subject to the conditions set forth herein;

WHEREAS, the Board of Directors of the Company (the “Company Board”) has (i) determined that it is in the best interests of the Company and its stockholders, and declared it advisable, to enter into this Agreement with Parent and Purchaser, (ii) approved the execution, delivery and performance of this Agreement, including the Offer, the Merger, the Top-Up Option and the issuance of Shares of Common Stock upon the exercise thereof and the other transactions contemplated hereby, (iii) resolved to recommend that the stockholders of the Company accept the Offer, tender their Shares pursuant to the Offer and adopt this Agreement and, if required to consummate the Merger, vote their Shares in favor of the adoption of this Agreement and (iv) directed that, if required to consummate the Merger, the adoption of this Agreement be submitted for consideration of the stockholders of the Company at the Company Stockholders Meeting;

WHEREAS, the Board of Directors of Parent has approved this Agreement and declared it advisable for Parent to enter into this Agreement;

WHEREAS, the Board of Directors of Purchaser has approved this Agreement and declared it advisable for Purchaser to enter into this Agreement and recommended that this Agreement be adopted by the Purchaser’s sole stockholder;

WHEREAS, immediately following execution of this Agreement by the parties hereto, this Agreement will be submitted to Parent, as the sole stockholder of Purchaser, and Parent, as the sole stockholder of Purchaser, will adopt this Agreement and approve the transactions contemplated by this Agreement by unanimous written consent in lieu of a meeting in accordance with the requirements of the Delaware General Corporation Law (the “DGCL”) and the certificate of incorporation and bylaws of Purchaser;

WHEREAS, as an inducement to and condition of Parent’s and Purchaser’s entering into this Agreement and incurring the obligations set forth herein, certain Stockholders of the Company as set forth on Section 4.7(b) of the Company Disclosure Letter have agreed to enter into tender and support agreements (each a “Stockholder Support Agreement” and, collectively, the “Stockholder Support Agreements”); and

WHEREAS, the parties desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and the transactions contemplated by this Agreement and also to prescribe certain conditions to the Offer and the Merger.

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

I. THE TENDER OFFER

Section 1.1. The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Article VIII hereof, Purchaser shall, and Parent shall cause Purchaser to, commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer as promptly as reasonably practicable following the execution of this Agreement, but not later than ten (10) Business Days following the date of this Agreement; provided, however, that such ten (10) Business Day period shall be extended to such date as the Company is ready to file the Schedule 14D-9 on the same date as the commencement of the Offer. The obligation of Purchaser to, and of Parent to cause Purchaser to, accept for payment and pay for any Shares tendered in the Offer and not withdrawn shall be subject to the satisfaction of those conditions set forth in Annex I. The conditions to the Offer set forth on Annex I are for the sole benefit of Parent and Purchaser and each of Parent and Purchaser expressly reserves the right from time to time, subject to Sections 1.1(b) and 1.1(d) hereof, to waive any such condition, to increase the Offer Price, or to make any other changes in the terms and conditions of the Offer. The Company agrees that no Shares held by the Company or any of its Subsidiaries shall be tendered pursuant to the Offer.

(b) Without the prior written consent of the Company, neither Parent nor Purchaser shall (i) decrease the Offer Price or change the form of consideration payable in

the Offer, (ii) decrease the number of Shares sought to be purchased in the Offer, (iii) amend or waive satisfaction of the Minimum Tender Condition (as defined in Annex I), (iv) impose conditions to the Offer in addition to the conditions to the Offer set forth on Annex I, (v) add to, amend or modify the conditions to the Offer set forth on Annex I in any manner that is adverse to the holders of the Shares, or (vi) undertake any extension of the Offer not specifically provided for or contemplated in this Agreement.

(c) The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) having such terms and conditions as are set forth in Annex I hereto. As soon as practicable on the date the Offer is commenced (within the meaning of Rule 14d-2 under the Exchange Act), Parent and Purchaser shall file with the Securities and Exchange Commission (the “SEC”) a Tender Offer Statement on Schedule TO (together with all amendments, exhibits and supplements thereto, the “Schedule TO”) with respect to the Offer that shall comply in all material respects with the provisions of all applicable federal securities laws, and shall contain (including as an exhibit) or incorporate by reference the Offer to Purchase and forms of the related letter of transmittal and summary advertisement (which documents, together with any supplements, exhibits or amendments thereto, and any other schedule or form which is filed in connection with the Offer and related transactions, are referred to collectively herein as the “Offer Documents”). The Parent and Purchaser shall give the Company one (1) Business Day advance notice prior to filing the Schedule TO. Parent and Purchaser shall disseminate the Offer Documents to holders of Shares as and to the extent required by applicable federal securities laws. The Company shall promptly furnish to Parent and Purchaser all information concerning the Company that may be required by applicable securities laws or reasonably requested by Parent or Purchaser for inclusion in the Schedule TO and the Offer Documents. Parent and Purchaser hereby further agree that the Schedule TO and the Offer Documents, when filed with the SEC and on the date first published, sent or given to the Company’s stockholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no representation or warranty is made by Parent or Purchaser with respect to information supplied by or on behalf of the Company specifically for inclusion or incorporation by reference in the Schedule TO or the Offer Documents. The Company hereby agrees that the information provided by or on behalf of the Company specifically for inclusion or incorporation by reference in the Schedule TO or the Offer Documents shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of Parent, Purchaser and the Company shall promptly correct any information provided by or on behalf of it for use in the Schedule TO or the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect. Parent and Purchaser shall take all steps necessary to cause the Schedule TO and the Offer Documents, as amended, to reflect such corrected information, to be filed with the SEC and the other Offer Documents, as amended to reflect such corrected information, to be disseminated to the Company’s stockholders, in each case as and to the extent required by applicable federal securities laws. The Company and its counsel shall be given a reasonable opportunity to review and comment on any Offer Documents before they are filed with the SEC, and Parent and Purchaser shall give due consideration to all the reasonable additions, deletions or changes suggested thereto by the Company and its counsel.

In addition, Parent and Purchaser shall provide the Company and its counsel with copies of any written comments, and shall inform them of any oral comments, that Parent, Purchaser or their counsel may receive from time to time from the SEC or its staff with respect to the Schedule TO or the Offer Documents promptly after receipt of such comments, and any written or oral responses thereto. The Company and its counsel shall be given a reasonable opportunity to review any such written responses and Parent and Purchaser shall give due consideration to all reasonable additions, deletions or changes suggested thereto by the Company and its counsel.

(d) Subject to the terms and conditions of this Agreement and the Offer, the Offer to Purchase shall provide that the Offer shall expire at midnight, New York time, on the date that is twenty (20) Business Days (for this purpose calculated in accordance with Rule 14d-1 promulgated under the Exchange Act) after the date the Offer is commenced (within the meaning of Rule 14d-2 promulgated under the Exchange Act). Purchaser agrees that it shall not terminate or withdraw the Offer or extend the expiration date of the Offer unless at the expiration date of the Offer the conditions to the Offer described in Annex I hereto shall not have been satisfied or earlier waived or, in the case of termination, such termination is in connection with the termination of this Agreement. Subject to the rights of the Purchaser to terminate this Agreement in accordance with Article VIII, if at the expiration date of the Offer, the conditions to the Offer described in Annex I hereto shall not have been satisfied or earlier waived, either the Company or Parent may cause Purchaser to for one (1) or more consecutive increments of not more than five (5) Business Days, extend the expiration date of the Offer until the date such conditions are satisfied or earlier waived and Purchaser becomes obligated to accept for payment and pay for Shares tendered pursuant to the Offer. Notwithstanding the foregoing, Parent may, without the consent of the Company, cause Purchaser to (i) extend the expiration date of the Offer (as it may be extended) for any period required by applicable rules, interpretations and regulations of the SEC in connection with the Offer and (ii) extend the expiration date of the Offer (as it may be extended) for up to two periods, each for up to five (5) Business Days, if on such expiration date the conditions for the Offer described on Annex I hereto shall have been satisfied or earlier waived, but the number of Shares that have been validly tendered and not withdrawn, when added to the Shares, if any, beneficially owned by Parent represents less than ninety percent (90%) of the then issued and outstanding Shares on a fully diluted basis. Notwithstanding the foregoing, (i) Purchaser (or Parent on its behalf) may, in its sole discretion, elect to provide a subsequent offering period for the Offer in accordance with Rule 14d-11 promulgated under the Exchange Act and (ii) in addition, Purchaser shall, if requested by the Company, make available a subsequent offering period in accordance with Exchange Act Rule 14d-11 of not less than ten (10) Business Days.

(e) Subject to the terms and conditions set forth in this Agreement and the Offer, Purchaser shall accept for payment and pay for all Shares validly tendered and not withdrawn pursuant to the Offer as promptly as practicable after the applicable expiration date of the Offer (as it may be extended) and in any event in compliance with Rule 14e-1(c) promulgated under the Exchange Act. The Offer Price payable in respect of each Share validly tendered and not withdrawn pursuant to the Offer or during any subsequent offering period shall be paid net to the holder thereof in cash, without interest, subject to reduction only for any dividends or other distributions declared thereon between the date hereof and the Acceptance Time. Parent shall provide, or cause to be provided to Purchaser, on a timely basis, the funds

necessary to pay for any Shares that Purchaser accepts or is obligated to accept for payment pursuant to the Offer.

Section 1.2. Company Actions.

(a) The Company hereby approves of and consents to the Offer and the other transactions contemplated by this Agreement. The Company hereby consents to the inclusion of the Company Board Recommendation in the Offer Documents, subject to the right of the Company Board to withdraw, modify or amend its recommendation in accordance with the provisions of Section 6.4 of this Agreement.

(b) Contemporaneous with the filing of the Schedule TO, the Company shall file with the SEC a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, and including all exhibits thereto, the “Schedule 14D-9”) that (i) shall comply in all material respects with the provisions of all applicable federal securities laws and (ii) shall include the opinion of X.X. Xxxxxx Securities Inc. referred to in Section 4.28 hereof. The Schedule 14D-9 and the Offer Documents shall contain the recommendations of the Company Board described in Section 1.2(a) hereof. The Company shall disseminate, and shall cooperate with Parent and Purchaser in disseminating, the Schedule 14D-9 and the Offer Documents to holders of Shares as and to the extent required by applicable federal securities laws. Each of Parent and Purchaser shall promptly furnish to the Company upon request all information concerning Parent and Purchaser that may be required by applicable securities laws or reasonably requested by the Company for inclusion in the Schedule 14D-9. The Company hereby further agrees that, when filed with the SEC and on the date first published, sent or given to the Company’s stockholders, the Schedule 14D-9 shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no representation or warranty is made by the Company with respect to information supplied by Parent or Purchaser specifically for inclusion or incorporation by reference in the Schedule 14D-9. Parent and Purchaser hereby agree that the information provided by them specifically for inclusion or incorporation by reference in the Schedule 14D-9 shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the Company, Parent and Purchaser shall promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect. The Company shall take all steps necessary to cause the Schedule 14D-9, as amended, to reflect such corrected information, to be filed with the SEC and disseminated to the Company’s stockholders, in each case as and to the extent required by applicable federal securities laws. The Company shall provide Parent, Purchaser and their counsel reasonable opportunity to review and comment on the Schedule 14D-9 prior to the filing thereof with the SEC, and the Company shall give due consideration to all the reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel. In addition, the Company shall provide Parent, Purchaser and their counsel with copies of any written comments, and shall inform them of any oral comments, that the Company or its counsel may receive from time to time from the SEC or its staff with respect

to the Schedule 14D-9 promptly after receipt of such comments, and any written or oral responses thereto. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review any such written responses and the Company shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel.

(c) In connection with the Offer, the Company shall, or shall cause its transfer agent to, promptly furnish Parent and Purchaser with mailing labels containing the names and addresses of all record holders of Shares, any available computer files containing the names and addresses of all record and beneficial holders of Shares and security position listings of Shares held in stock depositories, each as of a recent date, and shall promptly furnish Parent with such additional information, including updated lists of stockholders, mailing labels and security position listings, and such other information and assistance as Parent or its agents may reasonably request for the purpose of communicating the Offer to the record and beneficial holders of Shares. Except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer, the Merger and the other transactions contemplated by this Agreement, Parent and Purchaser shall hold in confidence the information contained in any such mailing labels, security position listings and files, shall use such information only in connection with the transactions contemplated hereby, including the Offer and the Merger.

Section 1.3. Company Board and Committees.

(a) Effective upon the initial acceptance for payment by Purchaser of Shares pursuant to the Offer (the “Acceptance Time”, the use of which term herein shall not, unless the context otherwise requires, depend upon whether Parent shall exercise its rights under this Section 1.3(a)), and from time to time thereafter, Parent shall be entitled to elect or designate directors to serve on the Company Board up to such number of directors equal to the product (rounded up to the next whole number) obtained by multiplying (x) the total number of directors on the Company Board (giving effect to any increase in the number of directors pursuant to this Section 1.3) by (y) a fraction, the numerator of which is the number of Shares held by Parent and Purchaser (giving effect to the Shares purchased pursuant to the Offer), and the denominator of which is the total number of then outstanding Shares. Promptly following a request by Parent, the Company shall use its best efforts (including by amending the Bylaws of the Company if necessary) to cause the individuals so designated by Parent to be elected or appointed to the Company Board, including (at the election of the Company) by increasing the size of the Company Board and/or by seeking and accepting the resignations of such number of then incumbent directors as is necessary to enable the individuals so designated by Parent to be elected or appointed to the Company Board. At such time, the Company shall also cause, if requested by Parent, the board of directors (or similar governing body) of each of the Company’s Subsidiaries to include Persons designated by Parent constituting the same percentage of each such board as Parent’s designees constitute on the Company Board. From time to time after the Acceptance Time, the Company shall take all actions necessary to cause the individuals so designated by Parent to constitute substantially the same percentage (rounding up where appropriate) as is on the Company Board on each committee of the Company Board and each committee of the Company’s Subsidiaries, in each case, to the fullest extent permitted by all

applicable Law and the rules of NASDAQ; provided, however, each committee shall be comprised of at least one Independent Director. If requested by Parent and permitted by the NASDAQ Marketplace Rules, promptly after the Acceptance Time, the Company shall take all action necessary to elect to be treated as a “controlled company” as defined by the NASDAQ Marketplace Rules and shall make all necessary filings and disclosures associated with such status.

(b) Until the Effective Time, the Company Board shall have at least two (2) directors who are directors of the Company on the date of this Agreement and who are not officers of the Company or any of its Subsidiaries (“Independent Directors”); provided. however, that if the number of Independent Directors shall be reduced below two (2) for any reason whatsoever (or if immediately following consummation of the Offer there are not at least two (2) then-existing directors of the Company who are (A) Qualified Persons and (B) willing to serve as Independent Directors), then the number of Independent Directors required hereunder shall be one (1), unless the remaining Independent Director is able to identify a person who is not then an officer or Affiliate of the Company, Parent or any of their respective Subsidiaries (any such person being referred to herein as a “Qualified Person”; it being understood that, for purposes of this definition, a person that would otherwise be considered an Affiliate of the Company shall not be deemed an Affiliate of the Company solely because he or she is a director of the Company) willing to serve as an Independent Director, in which case such remaining Independent Director shall be entitled to designate any such Qualified Person to fill such vacancy, and such designated Qualified Person shall be deemed to be an Independent Director for purposes of this Agreement, or if no Independent Directors then remain, the other directors shall be required to designate two (2) Qualified Persons to fill such vacancies, and such persons shall be deemed to be Independent Directors for purposes of this Agreement.

(c) The Company shall promptly take all actions required pursuant to this Section 1.3 and Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order to fulfill its obligations under this Section 1.3, including mailing to the Company’s stockholders the information required by such Section 14(f) and Rule 14f-1, and shall include in the Schedule 14D-9 such information with respect to the Company and its directors and officers as is required under such Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 1.3. The Company’s obligation to elect or appoint Parent’s designees to the Company Board pursuant to Section 1.3(a) hereof shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. Parent shall provide to the Company, and be solely responsible for any information with respect to itself and its nominees, directors, officers and Affiliates, required by such Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The provisions of this Section 1.3 are in addition to, and shall not limit, any right that Parent, Purchaser or any Affiliate of Parent or Purchaser may have (with respect to the election of directors or otherwise) under applicable Laws as a holder or beneficial owner of Shares.

(d) Notwithstanding anything to the contrary set forth in this Agreement, in the event that Parent’s designees are elected or appointed to the Company Board prior to the Effective Time pursuant to Section 1.3(a) hereof and there shall be any Independent Directors, the approval of a majority of such Independent Directors (or both Independent

Directors if there shall be only two (2) Independent Directors) shall be required in order to (i) amend or terminate this Agreement on behalf of the Company, (ii) extend the time for performance of, or waive, any of the obligations or other acts of Parent or Purchaser under this Agreement, if such actions would materially and adversely affect the holders of Shares (other than Parent or Purchaser), (iii) waive any of the Company’s rights under this Agreement if such waiver would materially and adversely affect the holders of Shares (other than Parent or Purchaser), or (iv) to take any other action of the Company Board under or in connection with this Agreement if such action would materially and adversely affect the holders of Shares (other than Parent or Purchaser).

Section 1.4. Top-Up Option.

(a) Top-Up Option.

(i) Subject to Section 1.4(a)(ii) and Section 1.4(a)(iii) hereof, the Company grants to Parent and Purchaser an assignable and irrevocable option (the “Top-Up Option”) to purchase from the Company the number of newly-issued shares of Common Stock (the “Top-Up Option Shares”) equal to the lesser of (i) the number of shares of Common Stock that, when added to the number of shares of Common Stock owned by Parent or Purchaser at the time of exercise of the Top-Up Option, constitutes one (1) Share more than 90% of the Shares of Common Stock then outstanding on a fully diluted basis (after giving effect to the issuance of the Top-Up Option Shares) or (ii) the aggregate number of shares of Common Stock that the Company is authorized to issue under its Certificate of Incorporation but that are not issued and outstanding (and are not subscribed for or otherwise committed to be issued) at the time of exercise of the Top-Up Option. The Top-Up Option shall be exercisable only once, at such time as Purchaser owns at least eighty percent (80%) of the shares of Common Stock then outstanding and provide notice of exercise of the Top-Up Option prior to the tenth (10) Business Day after the later of the expiration date of the Offer or the expiration date of any subsequent offering period.

(ii) Subject to the last sentence of Section 1.4(a)(i), the Top-Up Option may be exercised by Parent or Purchaser, in whole or in part, at any time at or after the Acceptance Time and prior to the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement pursuant to Article VIII; provided, however, that the Top-Up Option shall not be exercisable unless, immediately after such exercise and the issuance of shares of Common Stock pursuant thereto, Parent and Purchaser will collectively hold at least 90 percent (90%) of the Shares of Common Stock then outstanding (assuming the issuance of the Top-Up Option Shares). The aggregate purchase price payable for the shares of Common Stock being purchased by Parent or Purchaser pursuant to the Top-Up Option shall be determined by multiplying the number of such Top-Up Option Shares by the Offer Price. Such purchase price may be paid by Parent or Purchaser, at its election, either entirely in cash or by executing and delivering to the Company a promissory note having a principal amount equal to the purchase price. Any such promissory note shall bear interest at the rate of 3% per annum, shall mature not later than the fifth anniversary of the date of execution and delivery of such promissory note and may be prepaid without premium or penalty.

(iii) In the event Parent or Purchaser wishes to exercise the Top-Up Option, Parent or Purchaser shall deliver to the Company at least one (1) Business Day’s prior written notice setting forth (i) the number of shares of Company Common Stock that Parent or Purchaser intends to purchase pursuant to the Top-Up Option, (ii) the manner in which Parent or Purchaser intends to pay the applicable exercise price and (iii) the place and time at which the closing of the purchase of such Shares by Parent or Purchaser is to take place. At the closing of the purchase of such Shares of Common Stock, Parent or Purchaser shall cause to be delivered to the Company the consideration required to be delivered in exchange for such Shares, and the Company shall cause to be issued to Parent or Purchaser (as the case may be) a certificate representing such Shares. The obligation of the Company to issue Shares in connection with the exercise of the Top-Up Option is subject to the conditions that (x) no provision of any applicable Law and no judgment, injunction, order or decree shall prohibit the exercise of the Top-Up Option or the delivery of the Shares in respect of such exercise, (y) the issuance of Shares pursuant to the Top-Up Option would not require approval of the Company’s stockholders under applicable Law or regulation (including, without limitation, NASDAQ National Market rules and regulations, including Section 4350) and (z) Parent or Purchaser has accepted for payment and paid for all Shares validly tendered in the Offer and not withdrawn. The parties shall cooperate to ensure that the issuance of the Shares upon exercise of the Top-Up Option is accomplished in a manner consistent with all applicable legal requirements of any Governmental Entity, including compliance with an applicable exemption from registration of the Shares under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”).

Section 1.5. Stock Options/Restricted Shares/Employee Stock Purchase Plan.

(a) Treatment of Stock Options. Each option to purchase Shares (individually a “Stock Option” and collectively, the “Stock Options”) outstanding immediately prior to the Effective Time pursuant to any Equity Incentive Plan or otherwise shall, without any action on the part of any holder of any Option, become fully exercisable and vested immediately prior to the Effective Time. At the Effective Time, each Stock Option outstanding as of the Effective Time shall be cancelled and the holder of such Stock Option shall, in full satisfaction of such Stock Option and in exchange for the surrender to the Company of any certificate or other document evidencing such Stock Option, receive from the Company an amount (the “Option Consideration”) in cash equal to the product of (x) the excess, if any, of the Merger Consideration over the exercise price per Share of such Stock Option multiplied by (y) the number of Shares subject to such Stock Option (with the aggregate amount of such payment rounded up to the nearest whole cent). If the applicable exercise price of any Stock Option equals or exceeds the Merger Consideration, such Stock Option shall be cancelled without payment of additional consideration, and all rights with respect to such Stock Option shall terminate as of the Effective Time. Notwithstanding the foregoing, Parent and the Company shall be entitled to deduct and withhold from the Option Consideration otherwise payable such amounts as may be required for any applicable federal back-up withholding or other Taxes payable by the holder of such Stock Option. The holders of Stock Options shall have no further rights in respect of any Stock Options from and after the Acceptance Time. Within five (5) Business Days after the Effective Time, the Company shall pay the aggregate amount due to holders of Stock Options pursuant to this Section 1.5(a).

(b) Treatment of Restricted Shares. Immediately prior to the Acceptance Time, any then outstanding restricted shares of Company Common Stock issued pursuant to any Equity Incentive Plans or otherwise (the “Restricted Shares”) shall become fully vested and all restrictions thereon shall lapse. For the avoidance of doubt, holders of Restricted Shares shall be permitted to tender such Restricted Shares in to the Offer subject to the conditions and in accordance with the terms of the Offer.

(c) Treatment of Employee Stock Purchase Plan. Following the earlier to occur of (i) the end of the Purchase Interval (as defined in the ESPP) in effect as of the date hereof and (ii) the Acceptance Time, no additional payroll deductions (or other contributions) shall be made pursuant to the Company’s Employee Stock Purchase Plan (the “ESPP”). After the date hereof, no Participant (as defined in the ESPP) shall be permitted to increase the rate of his or her payroll deduction above the rate in effect as of the date hereof (or such lesser rate as may be reduced by the Participant following the date hereof). The rights of participants in the ESPP with respect to any offering period currently underway under the ESPP shall be determined by treating the earlier of (i) the last Business Day of the current Purchase Interval or (ii) the last Business Day prior to the Acceptance Time, as the last day of such offering period and by making such other pro-rata adjustments as may be necessary to reflect the shortened offering period but otherwise treating such shortened offering period as a fully effective and completed offering period for all purposes under the ESPP. As of the Acceptance Time, the ESPP shall be terminated.

(d) Treatment of Equity Incentive Plans. Effective as of the Effective Time, (i) the Equity Incentive Plans shall terminate, and (ii) no holder of a Stock Option issued pursuant to the Equity Incentive Plans or any other participant in the Equity Incentive Plans shall have any rights pursuant to an Equity Incentive Plan to acquire any equity securities of, or to receive any payments in consideration for any outstanding awards from, Parent, the Purchaser, the Company, the Surviving Corporation, or any of their respective Subsidiaries, except as expressly provided in this Section 1.5.

(e) Further Assurances. Prior to the Acceptance Time (or for purposes of Section 1.5(c), prior to the date hereof), the Company shall adopt such resolutions and shall take such other actions as may be required to effectuate the actions contemplated by this Section 1.5, without paying any consideration or incurring any debts or obligations on behalf of Parent, the Purchaser, the Company, the Surviving Corporation, or any of their respective Subsidiaries.

III. EFFECT OF THE MERGER ON CAPITAL STOCK

Section 3.1. Effect of the Merger on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of Parent, Purchaser or the Company or the holder of any shares of capital stock of Parent, Purchaser or the Company:

(a) Cancellation of Certain Common Stock. Each share of Common Stock that is owned by Parent, Purchaser (including Shares received in the Offer) or the Company (as treasury stock or otherwise) or any of their respective direct or indirect wholly-owned Subsidiaries (other than Shares held in a fiduciary capacity on behalf of third parties) shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(b) Conversion of Common Stock. Each Share issued and outstanding immediately prior to the Effective Time (other than (i) Shares to be cancelled and retired in accordance with Section 3.1(a) and (ii) Dissenting Shares (each, an “Excluded Share” and collectively, the “Excluded Shares”)) shall automatically be converted into the right to receive the Offer Price in cash, without interest (the “Merger Consideration”), subject to reduction for any dividends or other distributions declared thereon between the date hereof and the Effective Time payable upon surrender of such Shares in the manner provided in Section 3.2.

(c) Cancellation of Shares. At the Effective Time, all Shares (other than Excluded Shares) shall no longer be outstanding and all such Shares (other than Excluded Shares) shall automatically be cancelled and retired and shall cease to exist, and, subject to Section 3.3, each holder of a certificate formerly representing any such Shares (each, a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, without interest, in accordance with Section 3.2.

(d) Conversion of Purchaser Capital Stock. Each share of common stock, par value $0.0001 per share, of Purchaser issued and outstanding immediately prior to the Effective Time shall automatically be converted into one share of common stock, par value $0.0001 per share, of the Surviving Corporation.

Section 3.2. Surrender of Certificates.

(a) Paying Agent. Prior to the Effective Time, Purchaser shall designate, or cause to be designated, a bank or trust company that is reasonably acceptable to the Company (the “Paying Agent”) to act as agent for the holders of the shares for the payment of the Merger Consideration in respect of Certificates upon surrender of such Certificates (or effective affidavits of loss in lieu thereof) in accordance with this Article III from time to time after the Effective Time. Promptly after the Effective Time, Parent or Purchaser shall deposit, or cause to be deposited, with the Paying Agent cash in amounts and at the times necessary for the payment of the Merger Consideration pursuant to Section 3.1(b) upon surrender of such Certificates (such cash being herein referred to as the “Payment Fund”). Purchaser shall enter into a paying agent agreement on customary terms, which terms shall be in form and substance reasonably acceptable to the Company prior to the Effective Time. Pending disbursement to the holders of Shares, the Payment Fund shall be invested by the Paying Agent as directed by the Surviving Corporation; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, in certificates of deposit, bank repurchase agreements or banker’s acceptances of

commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank which are then publicly available) or in money market funds. Any net profit resulting from, or interest or income produced by, such investments shall be property of and payable to the Parent. Parent shall ensure that the Payment Fund is at all times sufficient to fully satisfy the cash payment obligations of Parent and Purchaser under this Agreement.

(b) Payment Procedures. As promptly as practicable after the Effective Time, the Surviving Corporation shall instruct the Paying Agent to mail to each holder of record of a Certificate which immediately prior to the Effective Time represented outstanding Shares (other than Excluded Shares), whose shares were converted pursuant to Section 3.1(b) into the right to receive the Merger Consideration, a letter of transmittal in customary form specifying that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates (or effective affidavits of loss in lieu thereof) to the Paying Agent and instructions for use in effecting the surrender of the Certificates (or effective affidavits of loss in lieu thereof) in exchange for the Merger Consideration. Upon the proper surrender of a Certificate (or effective affidavit of loss in lieu thereof) to the Paying Agent, together with a properly completed letter of transmittal, duly executed, and such other documents as may reasonably be requested by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor cash in the amount (after giving effect to any required Tax withholdings) that such holder has the right to receive pursuant to this Article III, and the Certificate so surrendered shall forthwith be cancelled. No interest shall be paid or accrued on any amount payable upon due surrender of the Certificates. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, cash to be paid upon due surrender of the Certificate may be paid 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 that any applicable stock transfer Taxes have been paid or are not applicable.

(c) Withholding Taxes. Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement to any holder of Shares any amounts that are required to be deducted and withheld with respect to such payments under the Code and the rules and Treasury Regulations promulgated thereunder, or any provision of state, local or foreign Tax Law. Any amounts so deducted and withheld shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares, as the case may be, in respect of which such deduction and withholding was made.

(d) No Further Transfers. The Merger Consideration paid in respect of Shares upon the surrender for exchange of Certificates in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares previously represented by such Certificates and at the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. From and after the Effective Time, the holders of Certificates that evidenced ownership of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with

respect to such shares, except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Paying Agent, they shall be cancelled and exchanged for the Merger Consideration as provided in this Article III.

(e) Termination of Payment Fund. Any portion of the Payment Fund that remains undistributed to the holders of the Certificates six months after the Effective Time shall be delivered to the Surviving Corporation, on demand, and any holder of a Certificate who has not theretofore complied with this Article III shall thereafter look only to the Surviving Corporation as a general creditor thereof for payment of his or her claims for Merger Consideration. Notwithstanding the foregoing, none of Parent, Purchaser, the Company, the Surviving Corporation, the Paying Agent or any other Person shall be liable to any former holder of Shares for any amount delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(f) Lost, Stolen or Destroyed Certificates. In the event any Certificate has 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 required by the Surviving Corporation, the posting by such Person of a bond in customary amount and upon such terms as the Surviving Corporation may determine are necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration pursuant to this Agreement.

Section 3.3. Appraisal Rights. Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, any Shares outstanding immediately prior to the Effective Time that are held by a stockholder (a “Dissenting Stockholder”) who has neither voted in favor of the adoption of this Agreement nor consented thereto in writing and who is entitled to demand and properly demands appraisal for such Shares and otherwise properly perfects and does not withdraw or lose his or her rights (the “Dissenting Shares”) in accordance with Section 262 of the DGCL shall not be converted into, or represent the right to receive, the Merger Consideration. Such Dissenting Stockholders shall be entitled to receive payment of the appraised value of Dissenting Shares held by them in accordance with the provisions of such Section 262, except that all Dissenting Shares held by stockholders who have failed to perfect or who effectively have withdrawn or lost their rights to appraisal of such Dissenting Shares pursuant to Section 262 shall thereupon be deemed to have been converted into, and represent the right to receive, the Merger Consideration in the manner provided in Article III and shall no longer be Excluded Shares. Notwithstanding anything to the contrary contained in this Section 3.3, if the Merger is rescinded or abandoned, then the right of any stockholder to be paid the fair value of such stockholder’s Dissenting Shares pursuant to Section 262 of the DGCL shall cease. The Company shall give Parent prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law received by the Company relating to stockholders’ rights of appraisal. The Company shall give Parent the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal or other treatment of any such demands.

Section 3.4. Adjustments to Prevent Dilution. In the event that the Company changes the number of Shares, or securities convertible or exchangeable into or exercisable for Shares, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Offer Price and the Merger Consideration shall be equitably adjusted to reflect such change; provided that nothing herein shall be construed to permit the Company to take any action with respect to its securities that is prohibited or not expressly permitted by the terms of this Agreement.

Each of the Company and its Subsidiaries is duly qualified or licensed to do business as a foreign corporation, limited liability company or other legal entity and is in good standing in each jurisdiction where the character of the assets and properties owned, leased or operated by it or the nature of its business makes such qualification or license necessary, except where the failure to be so qualified or licensed or in good standing would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. Neither the Company nor any of its Subsidiaries is in violation of its organizational or governing documents. Complete and correct copies of the Company Organizational Documents are attached hereto as Exhibit 4.1.

Section 4.2. Corporate Authorization; Enforceability. (a) The Company has all requisite corporate power and authority to enter into and to perform its obligations under this Agreement and, subject to adoption of this Agreement by the Requisite Company Vote in the case of the consummation of the Merger, to consummate the transactions contemplated by this Agreement.

Section 6.2. Other Actions. Parent, Purchaser and the Company shall not, and shall cause their respective Subsidiaries and controlled Affiliates not to, take any action that would reasonably be expected to, individually or in the aggregate, result in any of the conditions to either (i) the Offer set forth in Annex I to this Agreement or (ii) the Merger set forth in Article VII of this Agreement, in each case, not being satisfied or satisfaction of those conditions being materially delayed, except, in the case of the Company, to the extent the Company Board withdraws, modifies or amends the Company Board Recommendation to the extent permitted by Section 6.4(d).

Section 6.3. Access to Information; Confidentiality. (a) Subject to applicable Law, the Company shall provide and shall cause its Subsidiaries and its and their respective Representatives to provide Parent, Purchaser and their Representatives, during normal business hours and upon reasonable advance notice (i) such access to the directors, officers, management, employees, offices, properties, books and records, including environmental or regulatory audits, of the Company and such Subsidiaries (so long as such access does not unreasonably interfere with the operations of the Company) as Parent or Purchaser reasonably may request and (ii) all documents (including, without limitation, financial, operating and other data) that Parent or Purchaser reasonably may request. Notwithstanding the foregoing, Parent, Purchaser and their Representatives shall not have access to any books, records and other information the disclosure of which would, in the Company’s good faith opinion after consultation with legal counsel, result in the loss of attorney-client privilege with respect to such books, records and other information. The parties shall make appropriate substitute arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) No investigation by any of the parties or their respective Representatives shall affect the representations, warranties, covenants, conditions or agreements of the other parties set forth herein.

(i) initiate, solicit or knowingly encourage (including by way of providing information) or knowingly facilitate any inquiries, proposals or offers with respect to, or the making, announcement, submission or the completion of, a Takeover Proposal;

(ii) participate or engage in any discussions (other than to request clarification (and without providing any information regarding the Company to any third party) of an unsolicited Takeover Proposal that did not result from a breach of Section 6.4 to the

extent that outside counsel advises that such Takeover Proposal is not sufficiently clear to allow the Company Board to determine whether its fiduciary obligations would require it to exercise the rights of the Company under Section 6.4(d)) or negotiations with, or furnish or disclose any non-public information relating to the Company or any of its Subsidiaries to, or otherwise cooperate with, facilitate or assist any Person in connection with a Takeover Proposal;

(iii) withdraw, modify or amend the Company Board Recommendation in any manner adverse to Purchaser;

(iv) approve, endorse or recommend any Takeover Proposal;

(v) enter into any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to a Takeover Proposal, except that the Company may enter into an Acceptable Confidentiality Agreement as provided in Section 6.4(d); or

(vi) resolve, propose or agree to do any of the foregoing.

(b) The Company shall, and shall cause each of its Subsidiaries and Representatives to, immediately cease any existing solicitations, discussions or negotiations with any Person (other than the parties hereto) that has made or indicated an intention to make a Takeover Proposal. The Company shall promptly request that each Person who has executed a confidentiality agreement with the Company in connection with such Person’s consideration of a Takeover Proposal (other than the parties hereto and their respective advisors) return or destroy all non-public information furnished to that Person by or on behalf of the Company since January 1, 2008. The Company shall promptly inform its Representatives of the Company’s obligations under this Section 6.4. Any violation of Section 6.4(a) or 6.4(b) by any Representative of the Company or its Subsidiaries shall be deemed to be a breach of this Section 6.4 by the Company.

(c) The Company shall notify Purchaser promptly (and in any event within 48 hours) upon receipt by it or its Subsidiaries or Representatives of (i) any Takeover Proposal or indication by any Person that it is considering making a Takeover Proposal, (ii) any request for non-public information relating to the Company or any of its Subsidiaries other than requests for information in the ordinary course of business and unrelated to a Takeover Proposal or (iii) any inquiry or request for discussions or negotiations regarding any Takeover Proposal. The Company shall notify Purchaser promptly (and in any event within 48 hours) with the identity of such Person and a copy of such Takeover Proposal, indication, inquiry or request (or, where no such copy is available, a description of such Takeover Proposal, indication, inquiry or request), including any modifications thereto. The Company shall keep Purchaser reasonably informed on a current basis (and in any event within 24 hours of the occurrence of any changes) as to any material developments, discussions and negotiations with respect to any of the foregoing matters, including furnishing copies of any written proposals and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting the foregoing, the Company shall promptly (and in any event within 48 hours) notify Purchaser orally and in writing if it determines to begin providing information or to engage in discussions

or negotiations concerning a Takeover Proposal pursuant to Section 6.4(d). The Company shall not, and shall cause its Subsidiaries not to, enter into any confidentiality agreement with any Person subsequent to the date of this Agreement which prohibits the Company from providing such information to Purchaser. The Company shall not, and shall cause each of its Subsidiaries not to, terminate, waive, amend or modify any provision of any existing standstill or confidentiality agreement relating to a Takeover Proposal to which it or any of its Subsidiaries is a party, and the Company shall, and shall cause its Subsidiaries to, enforce the provisions of any such agreement.

(d) Notwithstanding the foregoing, the Company shall be permitted, if it has otherwise complied with its obligations under this Section 6.4, but only prior to the Acceptance Time, to:

(i) engage in discussions or negotiations with a Person who has made a written Takeover Proposal that was unsolicited and did not otherwise result from a breach of this Section 6.4 if, prior to taking such action, (A) the Company enters into an Acceptable Confidentiality Agreement with such Person and (B) the Company Board determines in good faith (1) after receiving the advice of its financial advisors and outside legal counsel, that such Takeover Proposal constitutes, or is reasonably likely to result in, a Superior Proposal and (2) after receiving the advice of its outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary obligations to the stockholders of the Company under applicable Laws;

(ii) furnish or disclose any non-public information relating to the Company or any of its Subsidiaries to a Person who has made a written Takeover Proposal that was unsolicited and did not otherwise result from a breach of this Section 6.4 if, prior to taking such action, the Company Board determines in good faith (A) after receiving the advice of its financial advisors and outside legal counsel, that such Takeover Proposal constitutes, or is reasonably likely to result in a Superior Proposal and (B) after receiving the advice of its outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary obligations to the stockholders of the Company under applicable Laws, but only so long as the Company (x) has caused such Person to enter into an Acceptable Confidentiality Agreement and (y) unless prohibited by applicable Law, concurrently discloses the same such non-public information to Purchaser if such non-public information has not previously been disclosed to Purchaser; and

(iii) except as expressly permitted by this Section 6.4(d)(iii), the Company Board shall not, (x) withdraw, modify or amend the Company Board Recommendation in a manner adverse to Parent or Purchaser or recommend or propose publicly to recommend such a Superior Proposal (a “Recommendation Change”) (it being understood and agreed that any change or development relating to any clinical trial of one or more products or product candidates of the Company or its Subsidiaries or any determination by the FDA or any other Governmental Entity relating thereto shall not be a basis for a Recommendation Change) or (y) terminate this Agreement to enter into, or otherwise authorize the entry into, any agreement in principle, letter of intent, merger agreement, acquisition agreement, option agreement or other similar agreement with respect to a Takeover Proposal, any termination to be effective only if in

advance of or concurrently with such termination the Company pays the Termination Fee and Purchaser Expenses in the manner provided for in Section 8.6(a); provided that the Company shall not be entitled to make a Recommendation Change or terminate this Agreement pursuant to this Section 6.4(d)(iii) unless: (1) the Company Board has determined in good faith, after consultation with outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary obligations to the stockholders of the Company under applicable Laws, (2) the Company shall have given Purchaser prompt written notice advising Purchaser of (A) the decision of the Company Board to take such action and (B) the material terms and conditions of any applicable Takeover Proposal, including the identity of the party making such Takeover Proposal and, if available, a copy of the relevant proposed transaction agreements with such party and other material documents, (3) the Company shall have given Parent three (3) Business Days (or one (1) Business Day in the event of each subsequent material revision to any applicable Takeover Proposal) after delivery of such notice to propose revisions to the terms of this Agreement (or make another proposal) and shall have negotiated in good faith with Parent with respect to such proposed revisions or other proposal, if any, and (4) at the end of such period, the Company Board shall have determined in good faith, after considering the results of such negotiations and giving effect to the proposals made by Purchaser, if any, after consultation with outside legal counsel, that (A) in the case of a Recommendation Change, failure to take such action would be inconsistent with its fiduciary obligations to the stockholders of the Company under applicable Laws and (B) in the case of a termination of this Agreement, that such Takeover Proposal remains a Superior Proposal relative to the Merger, as supplemented by any counterproposals made by Purchaser; provided that, in the event the Company Board does not make the determination referred to in clause (4) of this paragraph but thereafter determines to effect a Recommendation Change or to terminate this Agreement pursuant to this Section 6.4(d)(iii), the procedures referred to in clauses (1) — (4) above shall apply anew and shall also apply to any subsequent withdrawal, amendment or modification.

(e) Section 6.4(d) shall not prohibit the Company Board from disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act (other than any disclosure prohibited by Section 6.4(d)); provided, however, that any disclosure other than (i) as required in the Schedule 14D-9 pursuant to Section 1.2 or (ii) with respect to disclosures not required in the Schedule 14D-9 pursuant to Section 1.2, a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act shall be deemed to be a withdrawal, modification or amendment of the Company Board Recommendation in a manner adverse to Purchaser unless the Company Board (x) expressly reaffirms its recommendation to its stockholders in favor of adoption of this Agreement or (y) rejects such other Takeover Proposal.

(f) The Company shall not take any action to exempt any Person from the restrictions on “business combinations” contained in Section 203 of the DGCL (or any similar provisions) or otherwise cause such restrictions not to apply unless such actions are taken simultaneously with a termination of this Agreement.

Section 6.5. Notices of Certain Events. (a) The Company shall notify Purchaser promptly of (i) any communication from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this

Agreement (and the response thereto from the Company, its Subsidiaries or its Representatives), (ii) any communication from any Governmental Entity in connection with the transactions contemplated by this Agreement (and the response thereto from the Company, its Subsidiaries or its Representatives), (iii) any Legal Actions threatened or commenced against or otherwise affecting the Company or any of its Subsidiaries that are related to the transactions contemplated by this Agreement (and the response thereto from the Company, its Subsidiaries or its Representatives), (iv) any material events, changes, discussions, notices, changes or developments relating to pending material Legal Actions and (v) any event, change, occurrence, circumstance or development between the date of this Agreement and the Effective Time which causes or is reasonably likely to cause the conditions set forth in Section 7.1 of this Agreement or Annex I not to be satisfied or result in such satisfaction being materially delayed. With respect to any of the foregoing, the Company shall consult with Purchaser and its Representatives so as to permit the Company and Purchaser and their respective Representatives to cooperate to take appropriate measures to avoid or mitigate any adverse consequences that may result from any of the foregoing. Notwithstanding the foregoing, the delivery of any notice pursuant to this Section 6.5(a) shall not limit or otherwise affect the remedies available hereunder to Parent or Purchaser or the representations or warranties of the Company, or the conditions to the obligations of Parent and Purchaser hereto.

(b) Parent and Purchaser shall notify the Company promptly of (i) any communication from any Person alleging that the consent of such Person (or other Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from Purchaser or its Representatives), (ii) any communication from any Governmental Entity in connection with the transactions contemplated by this Agreement (and the response thereto from Parent, Purchaser or their Representatives), (iii) any Legal Actions threatened in writing or commenced against or otherwise effecting the Parent or Purchaser that are related to the transactions contemplated by this Agreement (and the responses thereto from the Parent or Purchaser), or (iv) any event, change, occurrence, circumstance or development between the date of this Agreement and the Effective Time which causes or is reasonably likely to cause the conditions set forth in Section 7.1 of this Agreement not to be satisfied or result in such satisfaction being materially delayed. Notwithstanding the foregoing, the delivery of any notice pursuant to this Section 6.5(b) shall not limit or otherwise affect the remedies available hereunder to the Company or the representations or warranties of Parent and Purchaser, or the conditions to the obligations of the Company hereto.

Section 6.6. Proxy Statement; Short-Form Merger; Company Stockholders Meeting. (a) If approval of the Company’s stockholders is required under Law in order to consummate the Merger other than pursuant to Section 253 of the DGCL, the Company shall, as promptly as practicable following the later of the Acceptance Time or the expiration of any subsequent offering period provided in accordance with Rule 14d-11 promulgated under the Exchange Act, (i) prepare and file with the SEC the Company Proxy Statement relating to the Merger and the other transactions contemplated hereby, (ii) respond as promptly as reasonably practicable to any comments received from the SEC with respect to such filings and shall provide copies of such comments to Purchaser promptly upon receipt, (iii) as promptly as reasonably practicable prepare and file (after Purchaser has had a reasonable opportunity to review and comment on) any amendments or supplements necessary to be filed in response to any SEC comments or as

required by Law, (iv) use all reasonable efforts to have cleared by the SEC and shall thereafter mail to its stockholders as promptly as reasonably practicable, the Company Proxy Statement and all other customary proxy or other materials for meetings such as the Company Stockholders Meeting, (v) to the extent required by applicable Law, as promptly as reasonably practicable prepare, file and distribute to the Company stockholders (in the case of the Company Proxy Statement) any supplement or amendment to the Company Proxy Statement if any event shall occur which requires such action at any time prior to the Company Stockholders Meeting, and (vi) otherwise use all reasonable efforts to comply with all requirements of Law applicable to the Company Stockholders Meeting and the Merger. Parent and Purchaser shall cooperate with the Company in connection with the preparation and filing of the Company Proxy Statement, including furnishing the Company upon request with any and all information as may be required to be set forth in the Company Proxy Statement under the Exchange Act. The Company shall provide Parent and Purchaser a reasonable opportunity to review and comment upon the Company Proxy Statement, or any amendments or supplements thereto, prior to filing the same with the SEC. Notwithstanding the foregoing, if Parent or Purchaser shall acquire at least 90 percent (90%) of the outstanding Shares on a fully diluted basis pursuant to the Offer or otherwise, and provided that the conditions set forth in Article VII shall have been satisfied or waived, the Company shall, at the request of Parent, take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after such acquisition, without the approval of the stockholders of the Company, in accordance with Section 253 of the DGCL.

(b) The Company Proxy Statement will include the Company Board Recommendation unless the Company Board has withdrawn, modified or amended the Company Board Recommendation to the extent permitted under Section 6.4(d).

(c) If approval of the Company’s stockholders is required under Law in order to consummate the Merger other than pursuant to Section 253 of the DGCL, the Company shall, as promptly as practicable following the later of the Acceptance Time or the expiration of any subsequent offering period provided in accordance with Rule 14d-11 promulgated under the Exchange Act, establish a record date for, call, give notice of, convene and hold the Company Stockholders Meeting for the purpose of obtaining the Requisite Company Vote. The written consent of Purchaser will be required to adjourn or postpone the Company Stockholder Meeting. The Company shall, unless a Recommendation Change permitted by Section 6.4(d)(iii) has occurred, (a) use all reasonable efforts to solicit or cause to be solicited from its stockholders proxies in favor of adoption of this Agreement and (b) take all other reasonable action necessary to secure the Requisite Company Vote. Notwithstanding anything herein to the contrary, unless this Agreement is terminated in accordance with Section 8.1, 8.2, 8.3 or 8.4, the Company shall take all of the actions contemplated by this Section 6.6 regardless of whether the Company Board has approved, endorsed or recommended another Takeover Proposal or has withdrawn, modified or amended the Company Board Recommendation, and shall submit this Agreement for adoption by the stockholders of the Company at such meeting. The Company shall keep Parent updated with respect to the proxy solicitation results as reasonably requested by Parent. Each of Parent and Purchaser shall vote all Shares acquired in the Offer (or otherwise beneficially owned by them or any of their respective Subsidiaries as of the applicable record date) in favor of the adoption of this Agreement in accordance with applicable Law at the Company Stockholders Meeting. Parent shall vote all of

the shares of capital stock of Purchaser beneficially owned by it in favor of the adoption of this Agreement in accordance with applicable Law.

Section 6.7. Employees; Benefit Plans.

(a) Parent agrees that all employees of the Company or its Subsidiaries will, by operation of law, either become or continue employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation immediately following the Effective Time. Each employee of the of the Company or its Subsidiaries who continues or commences employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation immediately following the Effective Time (each, a “Continuing Employees”) will be eligible to participate in either, at the sole discretion of Parent: (i) Parent’s employee benefit plans and programs, including any equity incentive plan, pension plan, defined benefit plan, defined contribution plan, Section 401(k) plan, bonus plan, profit sharing plan, severance plan, medical plan, dental plan, life insurance plan, time-off programs and disability plan, in each case to the same extent as similarly situated employees of Parent; or (ii) such Company Benefit Plans as are continued by the Company or any of its Subsidiaries following the Closing Date, or are assumed by Parent (for the purposes of this Section 6.7 only, the plans referred to in clauses “(i)” and “(ii)” of this sentence being referred to as “Specified Parent Benefit Plans”). Except as may otherwise be agreed between Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation and a Continuing Employee, for the period commencing at the Effective Time and ending at the close of business on December 31, 2008, each Continuing Employee shall be entitled to receive, while in the employ of Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation, at least the same cash salary or hourly wage rate, and annual cash bonus opportunity as were provided to such Continuing Employee by the Company or its Subsidiaries immediately prior to the Effective Time. Nothing in this Agreement shall in any way limit the ability of Parent or the Surviving Corporation, or any subsidiary thereof, to terminate any Continuing Employee.

(b) Each Continuing Employee shall, to the extent permitted by applicable Law, receive full credit for the years of continuous service by such Continuing Employee recognized by the Company or its Subsidiaries prior to the Effective Time for purposes of (i) satisfying the service requirements for participation in each Specified Parent Benefit Plan, (ii) vesting in any benefits under such plans, and (iii) calculating the level of benefits with respect to severance, vacation, personal days off and any other welfare-type benefits where service is a factor in calculating benefits, except where such credit would result in a duplication of benefits. With respect to any welfare benefit plans maintained by Parent for the benefit of Continuing Employees located in the United States, subject to any applicable plan provisions, contractual requirements or Laws, Parent shall (to the extent that such limitation would not apply with respect to substantially similar plans maintained by the Company or its Subsidiaries prior to the Effective Time), (A) cause to be waived any eligibility requirements or pre-existing condition limitations, and (B) give effect, in determining any deductible maximum out of pocket limitations, to amounts paid by such Continuing Employees during the plan year in which the Effective Time occurs.

(c) If requested by Parent at least five business days prior to the Closing Date, the Company shall take (or cause to be taken) all actions reasonably necessary pursuant to resolutions of the Company Board necessary or appropriate to terminate, effective no later than the day prior to the Closing Date, any Company Benefit Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (a “Company 401(k) Plan”). If the Company is required to terminate any Company 401(k) Plan, then the Company shall provide to Parent prior to the Closing Date written evidence of the adoption by the Company Board of resolutions authorizing the termination of such Company 401(k) Plan (the form and substance of which resolutions shall be subject to the prior review and approval of Parent, which approval shall not be unreasonably withheld or delayed).

(d) As of the date hereof, Parent shall, or shall cause the Purchaser to, establish a retention bonus plan for the benefit of certain employees of the Company. The material terms of the retention bonus are set forth on Section 6.7(d) of the Company Disclosure Letter.

(e) Nothing contained in this Section 6.7, express or implied: (i) shall be construed to establish, amend, or modify any benefit plan, program, agreement or arrangement, (ii) shall alter or limit the ability of any of Parent, the Purchaser, the Company, the Surviving Corporation, or any of their respective Subsidiaries to amend, modify or terminate any benefit plan, program, agreement or arrangement at any time assumed, established, sponsored or maintained by any of them, (iii) is intended to confer upon any current or former employee any right to employment or continued employment for any period of time by reason of this Agreement, or any right to a particular term or condition of employment, or (iv) is intended to confer upon any Person (including for the avoidance of doubt any Continuing Employee) any right as a third-party beneficiary of this Agreement.

Section 6.8. Directors’ and Officers’ Indemnification and Insurance. (a) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including any such claim, action, suit, proceeding or investigation, in which any present or former director or officer of the Company or any of its Subsidiaries (together, the “Indemnified Parties”) is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining in whole or in part to, any action or failure to take action by any such Person in such capacity taken prior to the Effective Time, the Surviving Corporation (the “Indemnifying Party”) shall, from and after the Effective Time, indemnify, defend and hold harmless, as and to the fullest extent permitted or required by applicable Law or the Company Organizational Documents (or any similar organizational document) of the Company or any of its Subsidiaries, when applicable, and any indemnity agreements applicable to any such Indemnified Party or any Contract between an Indemnified Party and the Company or one of its Subsidiaries, in each case, in effect on the date of this Agreement, against any losses, claims, damages, liabilities, costs, legal and other expenses (including reimbursement for reasonable legal and other fees and expenses incurred in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party), judgments, fines and amounts paid in settlement actually and reasonably incurred by such Indemnified Party in connection with such claim, action, suit, proceeding or investigation, subject to the Surviving Corporation’s receipt of an undertaking by such Indemnified Party to

repay such legal and other fees and expenses paid in advance if it is ultimately determined that such Indemnified Party is not entitled to be indemnified under applicable Law; provided, however, that the Surviving Corporation shall not be liable for any settlement effected without the Surviving Corporation’s prior written consent and shall not be obligated to pay the fees and expenses of more than one counsel (selected by a plurality of the applicable Indemnified Parties) for all Indemnified Parties in any jurisdiction with respect to any single such claim, action, suit, proceeding or investigation.

(b) The Company may, or the Surviving Corporation shall obtain prior to the Effective Time “tail” insurance policies with a claims period of six years from the Effective Time with at least the same coverage and amounts and containing terms and conditions that are not less advantageous in the aggregate to the directors and officers of the Company, in each case with respect to claims arising out of or relating to events which occurred before or at the Effective Time; provided, however that in no event will the Surviving Corporation be required to expend an annual premium for such coverage in excess of 250% of the last annual premium paid by the Company for such insurance prior to the date of this Agreement (the “Maximum Premium”). If such insurance coverage cannot be obtained at all, or can only be obtained at an annual premium in excess of the Maximum Premium, the Surviving Corporation shall obtain that amount of directors’ and officers’ insurance (or “tail” coverage) obtainable for an annual premium equal to the Maximum Premium. The Company represents that its current annual premium for director and officer insurance is set forth in Section 6.8(b) of the Company Disclosure Letter.

(c) The provisions of this Section 6.8 will survive the Closing and, after the Effective Time, are intended to be for the benefit of, and will be enforceable by, each Indemnified Party and its successors and representatives after the Effective Time and their rights under this Section 6.8 are in addition to, and will not be deemed to be exclusive of, any other rights to which an Indemnified Party is entitled, whether pursuant to Law, Contract, the Company Organizational Documents (or similar organizational document) of the Surviving Corporation or any of its Subsidiaries or otherwise.

(d) Following the Effective Time, the Surviving Corporation and each of its Subsidiaries shall include and maintain in effect in their respective certificates of incorporation or bylaws (or similar organizational document) for a period of six years after the Effective Time, provisions regarding the elimination of liability of directors (or their equivalent), indemnification of officers and directors thereof and advancement of expenses which are, in the aggregate with respect to each such entity, no less advantageous to the intended beneficiaries than the corresponding provisions contained in such organizational documents as of the date of this Agreement.

(e) In the event that the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Persons, or (ii) transfers all or substantially all of its properties or assets to any Person, then and in each case, proper provision will be made so that the applicable successors, assigns or transferees assume the obligations set forth in this Section 6.8.

Section 6.9. Reasonable Efforts. (a) Upon the terms and subject to the conditions set forth in this Agreement and in accordance with applicable Laws, each of the parties to this Agreement shall use all commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to ensure that the conditions to the Offer set forth on Annex I hereto and the conditions to the Merger set forth in Article VII are satisfied and to consummate the transactions contemplated by this Agreement as promptly as practicable, including (i) obtaining all necessary actions or nonactions, waivers, consents and approvals from Governmental Entities and making all necessary registrations and filings and taking all steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) making, an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby, by Parent as soon as practicable and by the Company within 10 calendar days of the date of receipt of Parent’s filing by the U.S. Federal Trade Commission (the “FTC”) and the Antitrust Division of the U.S. Department of Justice (the “Antitrust Division”), (iii) making, as promptly as practicable, appropriate filings under the competition, trade regulation, or merger control Laws of any other applicable jurisdiction as determined by Parent and Company, (iv) obtaining all necessary or appropriate consents and waivers under any and all Contracts, Leases and Permits to which the Company or its Subsidiaries is a party in connection with this Agreement and the consummation of the transactions contemplated hereby (including the Offer and the Merger) so as to maintain and preserve the benefits under such Contracts, Leases or Permits following the consummation of the transactions contemplated hereby (including the Offer and the Merger), and (v) obtaining all consents, approvals or waivers from, or taking other actions with respect to, third parties necessary or advisable to be obtained or taken in connection with the transactions contemplated by this Agreement; provided, however, that without the prior written consent of Purchaser, the Company and its Subsidiaries may not pay or commit to pay any amount of cash or other consideration, or incur or commit to incur any liability or other obligation, in connection with obtaining such consent, approval or waiver.

(b) Parent, Purchaser and the Company shall cooperate and consult with each other in connection with the making of all such filings, notifications and any other material actions pursuant to this Section 6.9, subject to applicable Law, by permitting counsel for the other party to review in advance, and consider in good faith the views of the other party in connection with, any proposed material written communication to any Governmental Entity and by providing counsel for the other party with copies of all filings and submissions made by such party and all correspondence between such party (and its advisors) with any Governmental Entity and any other information supplied by such party and such party’s Affiliates to a Governmental Entity or received from such a Governmental Entity in connection with the transactions contemplated by this Agreement; provided, however, that material may be redacted (x) as necessary to comply with contractual arrangements, and (y) as necessary to address good faith legal privilege or confidentiality concerns. Provided that the Company is not legally required to file such document, the Company shall not file any such document or take such action if Purchaser has reasonably objected (and not withdrawn its objection) to the filing of such document or the taking of such action on the grounds that such filing or action would reasonably be expected to either (i) prevent, materially delay or materially impede the consummation of the transactions contemplated hereby or (ii) cause a condition set forth in Article VII to not be satisfied in a timely manner. The Company shall not consent to any voluntary extension of any

statutory deadline or waiting period or to any voluntary delay of the consummation of the transactions contemplated by this Agreement at the behest of any Governmental Entity without the consent of Purchaser.

(c) Each of Parent, Purchaser and the Company shall promptly inform the other party upon receipt of any material communication from the FTC, the Antitrust Division or any other Governmental Entity regarding any of the transactions contemplated by this Agreement. If Parent, Purchaser or the Company (or any of their respective Affiliates) receives a request for additional information or documentary material from any such Governmental Entity that is related to the transactions contemplated by this Agreement, then such party shall endeavor in good faith to make, or cause to be made, as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request. The parties agree not to participate, or to permit their Affiliates to participate, in any substantive meeting or discussion with any Governmental Entity in connection with the transactions contemplated by this Agreement unless it so consults with the other party in advance and, to the extent not prohibited by such Governmental Entity, gives the other party the opportunity to attend and participate.

Section 9.11. Severability.

Notwithstanding the foregoing, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.

Furthermore, notwithstanding any other term of the Offer or this Agreement, neither Parent nor Purchaser shall be required to commence the Offer or accept for payment or, subject as aforesaid, to pay for, and may delay the acceptance for payment of, any Shares tendered pursuant to the Offer if, at any time on or after the date of this Agreement (unless cured as contemplated by Section 8.3(c)) and before the expiration or termination of the Offer, any of the following conditions exists:

(b) since the date of this Agreement, there shall have occurred or been discovered any event, change, occurrence or development that, individually or in the aggregate, has had or would reasonably be expected to have, a Company Material Adverse Effect; or

(c) (i) the representations and warranties of the Company contained in this Agreement shall not be true and correct at such time (except to the extent expressly made as of an earlier date, in which case as of such earlier date), in each case except where the failure of any such representations and warranties to be so true and correct (without giving effect to any limitation on any representation or warranty indicated by the words “materiality” or “Company

Material Adverse Effect” or “Knowledge of the Company”) would not, or would not reasonably be expected to, individually or in the aggregate, have a Company Material Adverse Effect on the Company, or (ii) the representations and warranties of the Company set forth in Sections 4.2, 4.3(a), 4.3(d), 4.3(h), and 4.7(a) shall not be true and correct in all respects at such time (except, in the case of Section 4.3(a), for such inaccuracies as are de minimis in the aggregate);

(d) the Company shall have failed to perform in all material respects all obligations, or failed to comply in all material respects with the agreements and covenants, required to be performed by or complied with by it pursuant to the Agreement; or

(e) this Agreement shall have been terminated in accordance with its terms; or

(f) the Company shall have failed to deliver to Parent a certificate executed on behalf of the Company by the chief executive officer and chief financial officer of the Company certifying that such officers have read the matters set forth in sections (b), (c) and (d) that such matters have not occurred.

The foregoing conditions are for the sole benefit of Parent and Purchaser and subject to the terms and conditions of this Agreement, may be waived by Parent or Purchaser, in whole or in part, at any time, at the sole discretion of Parent or Purchaser. The failure by Parent, Purchaser or any other Affiliate of Parent at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, the waiver of any such right with respect to particular facts and circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.
