RECITALS

1. Buyer, Merger Sub and Seller intend to effect a merger (the “Merger”) of Merger Sub with and into Seller in accordance with this Agreement and the General Corporation Law of the State of Delaware (the “DGCL”), with Seller to be the surviving corporation of the Merger.

2. The respective Boards of Directors of Buyer, Merger Sub and Seller have declared that it is advisable and in the best interests of Buyer, Merger Sub and Seller and their respective stockholders to consummate, and have approved this Agreement and the transactions provided for herein, pursuant to which, subject to the terms and conditions set forth herein, the Merger shall occur.

3. Concurrently with the execution and delivery of this Agreement, and as a condition and inducement to Buyer to enter into this Agreement, each of the employees of Seller or its Subsidiaries listed on Exhibit A hereto (the “Key Employees”) has executed and delivered a letter confirming his or her continuation of employment with the Surviving Corporation to be effective immediately after the Closing (each, a “Key Employee Letter”) and an intellectual property protection agreement (each, an “IP Protection Agreement”), each on forms acceptable to Buyer.

4. As an inducement to the willingness of Buyer and Merger Sub to enter into this Agreement (but not pursuant to any prior agreement with Seller or Buyer), (i) holders of at least 67% of the outstanding shares of Seller Stock (as defined below), voting together as a single class and on an as-converted basis, (ii) holders of at least two-thirds of the outstanding shares of Seller Series A Stock (as defined below), voting as a separate series, (iii) holders of at least a majority of the outstanding shares of Seller Series B Stock (as defined below), voting as a separate series; and (iv) holders of at least a majority of the outstanding shares of Seller Common Stock (as defined below), voting as a separate class, have indicated that they expect to deliver, following the approval and adoption of this Agreement by the Board of Directors of the Seller and immediately following the execution and delivery of this Agreement, (i) their irrevocable adoption of this Agreement and approval of the Merger and the other transactions contemplated hereby and (ii) specified undertakings, representations, warranties, releases and waivers, pursuant to a written consent in the form attached hereto as Exhibit B and a joinder, release and waiver in the form attached hereto as Exhibit C (the “Joinder and Waiver Agreement”), respectively, signed and dated as of the date hereof by such Seller Stockholders, pursuant to and in accordance with the applicable provisions of the DGCL, the California Corporations Code and the Seller Charter (such consents of such Seller Stockholders in the forms of Exhibit B and Exhibit C, collectively, the “Stockholders’ Consent”).

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

ARTICLE I - THE MERGER

1.1 The Merger. Upon the terms and subject to the satisfaction or waiver of the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time, Merger Sub shall merge with and into Seller. Seller shall continue as the surviving corporation (the “Surviving Corporation”) in the Merger and shall continue its corporate existence under the laws of the State of Delaware. Upon consummation of the Merger, the separate corporate existence of Merger Sub shall terminate.

1.2 Effective Time. The Merger shall become effective as set forth in the certificate of merger (the “Certificate of Merger”), executed in accordance with the relevant provisions of the DGCL, which shall be filed with the Secretary of State of the State of Delaware on or before the Closing Date. The term “Effective Time” shall be the date and time when the Merger becomes effective as set forth in the Certificate of Merger.

1.3 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place at the offices of Goodwin Procter LLP, Exchange Place, Boston, Massachusetts, unless another place is agreed to in writing by the parties hereto, at 10:00 a.m., local time, on a date (the “Closing Date”) specified by the parties, which shall be the final Business Day of the calendar month in which the satisfaction or waiver (subject to applicable Law) of the latest to occur of the conditions set forth in Article VII (other than those conditions that relate to action to be taken at the Closing, but subject to satisfaction of such conditions at the Closing) occurs, unless this Agreement has been theretofore terminated pursuant to its terms or unless extended by mutual agreement of the parties.

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in this Agreement and in the appropriate provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, the Surviving Corporation shall possess all the rights, privileges, powers and franchises, and be subject to all of the restrictions, disabilities, and duties of Seller and Merger Sub, as provided under Section 259 of the DGCL.

1.5 Certificate of Incorporation and Bylaws. At the Effective Time, the Amended and Restated Certificate of Incorporation of Seller (the “Seller Charter”), as in effect immediately prior to the Effective Time, shall be amended to be identical to the Certificate of Incorporation of Merger Sub (the “Merger Sub Charter”), as in effect immediately prior to the Effective Time (which shall contain such provisions as are necessary to give full effect to the exculpation, reimbursement, advancement of expenses, contribution and indemnification provided for in Section 6.7 hereof), except the name of Seller as the Surviving Corporation shall be Apache Design Solutions, Inc. and the provisions of the Merger Sub Charter relating to the

incorporator of the Merger Sub shall be omitted, and as so amended shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided and in accordance with the DGCL (the “Surviving Corporation Charter”). From and after the Effective Time, the Bylaws of Seller (the “Seller Bylaws”), as in effect immediately prior to the Effective Time, shall be amended and restated to be identical to the Bylaws of Merger Sub as in effect immediately prior to the Effective Time (which shall contain such provisions as are necessary to give full effect to the exculpation, reimbursement, advancement of expenses, contribution and indemnification provided for in Section 6.7 hereof), and as so amended shall be the Bylaws of the Surviving Corporation, until thereafter amended as provided therein and in accordance with applicable Law (the “Surviving Corporation Bylaws”).

1.6 Directors and Officers.

(a) From and after the Effective Time, the directors of the Surviving Corporation shall be James E. Cashman III, Dr. Andrew T. Yang, Emily Chang, Maria T. Shields, Sheila DiNardo and Lee Detwiler, until their successors are duly elected, appointed or qualified or until their earlier death, resignation, or removal in accordance with the Surviving Corporation Charter and the Surviving Corporation Bylaws.

(b) From and after the Effective Time, the officers of Seller at the Effective Time shall be the officers of the Surviving Corporation, until their successors are duly elected, appointed or qualified or until their earlier death, resignation, or removal in accordance with the Surviving Corporation Charter and the Surviving Corporation Bylaws.

ARTICLE II - EFFECT OF THE MERGER ON THE SELLER CAPITAL STOCK; EXCHANGE OF SHARES

2.1 Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of any party hereto or of the holder of any shares of the capital stock of Seller or capital stock of Merger Sub:

(a) Capital Stock of Merger Sub. Each share of the common stock of Merger Sub, par value $0.0001 per share (the “Merger Sub Common Stock”), issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid, and nonassessable share of common stock, $0.0001 par value per share, of the Surviving Corporation.

(b) Cancellation of Certain Stock. All shares of common stock, $0.0001 par value per share, of Seller (“Seller Common Stock”), Series A Preferred Stock, par value $0.0001 per share, of Seller (“Seller Series A Stock”) and Series B Preferred Stock, par value $0.0001 per share, of Seller (“Seller Series B Stock”), and, together with Seller Common Stock and Seller Series A Stock, “Seller Stock”) that are owned by Seller or any wholly owned Subsidiary of Seller and any shares of Seller Common Stock owned by Buyer, Merger Sub, or any other wholly owned Subsidiary of Buyer immediately prior to the Effective Time shall be cancelled and shall cease to exist and no consideration shall be delivered in exchange therefor.

(c) Conversion of Seller Stock. Subject to Section 2.9, other than Dissenting Shares, at the Effective Time, by virtue of the Merger and without any action on the part of the

Buyer, the Seller or the Seller Stockholders, each share of Seller Stock shall be converted into a right to receive a portion of the Merger Consideration in accordance with this Agreement, and the Merger Consideration shall be allocated among, and payment shall be paid by Buyer through the Payment Agent to, the Seller Stockholders in accordance with Section 2.2. As of the Effective Time, all shares of Seller Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such shares of Seller Stock shall cease to have any rights with respect thereto, except the right to receive the applicable Merger Consideration, pursuant to this Section 2.1(c), subject to the provisions of this Agreement. From and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Seller Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, stock certificates of Seller are presented to the Surviving Corporation or the Payment Agent for any reason, they shall be cancelled and exchanged as provided in this Article 2.

(d) Seller Stock Options and Related Matters.

(i) As soon as practicable following the date of this Agreement, but in any event prior to the Closing Date, the Board of Directors of Seller (or, if appropriate, any committee administering the Seller Stock Option Plans) shall adopt such resolutions or use its reasonable best effort to take such other actions as are required to provide for the conversion of each Seller Stock Option as provided in this Section 2.1(d).

(ii) At the Effective Time, each Seller Stock Option that is outstanding, unexercised, vested and exercisable immediately prior to the Effective Time, after giving effect to any acceleration of vesting applicable to such Seller Stock Option in connection with the Merger (“Vested Options”), shall be cancelled in exchange for the right to receive a portion of the Merger Consideration from Buyer as set forth in Section 2.2(c)(iv). On and after the Effective Time, the Vested Options shall terminate and cease to be outstanding. All amounts payable pursuant to this Section 2.1(d)(ii) shall be subject to any required tax withholding.

(iii) At the Effective Time, each Seller Stock Option that is outstanding, unexercised and not vested and exercisable immediately prior to the Effective Time, after giving effect to any acceleration of vesting applicable to such Seller Stock Option in connection with the Merger (“Assumed Options”), shall be converted into and become an option to purchase shares of common stock, par value $.01 per share (“Buyer Common Stock”) of Buyer as provided below in this Section 2.1(d)(iii), and Buyer shall assume such Assumed Option in accordance with this Section 2.1(d)(iii) and the terms (as in effect as of the date of this Agreement) of the Seller Stock Option Plans and/or the seller option agreement by which such Assumed Option is evidenced. All rights to purchase Seller Common Stock under Assumed Options shall, effective as of the Effective Time, thereupon be converted into rights to purchase Buyer Common Stock. Accordingly, from and after the Effective Time: (A) each Assumed Option may be exercised solely for Buyer Common Stock; (B) the number of shares of Buyer

Common Stock subject to each Assumed Option shall be determined by multiplying the number of shares of Seller Common Stock that were subject to such Assumed Option immediately prior to the Effective Time by the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Buyer Common Stock; (C) the per share exercise price for the Buyer Common Stock issuable upon exercise of each Assumed Option shall be determined by dividing the per share exercise price of Seller Common Stock subject to such Assumed Option, as in effect immediately prior to the Effective Time, by the Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent; and (D) any restriction on the exercise of any Assumed Option shall continue in full force and effect and the term, exercisability, vesting schedule (including acceleration of vesting agreements in existence) and other provisions of such Assumed Option shall otherwise remain unchanged as a result of the conversion of such Assumed Option or otherwise. Buyer shall file with the SEC, no later than thirty (30) days after the Closing, a registration statement on Form S 8 (or any successor form), relating to the shares of Buyer Common Stock issuable with respect to the Assumed Options.

2.2 Merger Consideration.

(a) The aggregate consideration (collectively, the “Merger Consideration”) to be paid by Buyer to the Seller Securityholders is: (a) $275,000,000 minus (b) the amount of Seller Transaction Expenses plus or minus (c) the amount of the Net Cash Balance, if any, as determined pursuant to Section 2.4 minus (d) the amount of Final Indebtedness of Seller and its Subsidiaries outstanding as of Closing plus (e) if and when earned, the amount of any Contingent Payments pursuant to Section 2.6.

(b) Immediately following the Effective Time, Buyer shall pay the following amounts by wire transfer of immediately available funds: (i) the amount of Seller Transaction Expenses outstanding at Closing shall be paid to the parties designated on the Seller Schedule and (ii) an amount equal to (A) $275,000,000 minus (B) the amount payable pursuant to clause (i) of this Section 2.2(b) plus (C) the Preliminary Net Cash Surplus, if any, minus (D) the Preliminary Net Cash Deficit, if any, minus (E) the amount of Estimated Indebtedness (such amount pursuant to this clause (ii), the “Initial Merger Consideration”) of which (W) $15,000,000 shall be paid to and deposited with the Escrow Agent pursuant to Section 2.3 (the “General Escrow Amount”), (X) $2,000,000 shall be paid to and deposited with the Escrow Agent solely to secure the payment obligations of the Sellers, if any, pursuant to Section 2.4 (the “Net Cash Escrow Amount”), (Y) $3,500,000 shall be paid to and deposited with the Escrow Agent solely to secure the payment obligations of the Sellers pursuant to Section 6.13 (the “Tax Escrow Amount”) and (Z) $500,000 shall be paid and deposited with an account to be designated by the Securityholders’ Representative to fund the costs and expenses of the Securityholders’ Representative pursuant to the terms of this Agreement and the Escrow Agreement (the “Securityholders’ Representative Expense Fund”). The remainder of the Initial Merger Consideration shall be paid to the Payment Agent for subsequent payment to the Seller Securityholders pursuant to Section 2.2(c), subject to the procedures set forth in Section 2.7 and the Payment Agent Agreement (such remainder, the “Closing Payment”).

(c) The Closing Payment shall be paid to the Seller Securityholders following Closing by the Payment Agent pursuant to Section 2.7 and the Payment Agent Agreement as follows:

(i) The holders of Seller Common Stock and Seller Preferred Stock, on an as-converted basis, shall be entitled to an amount per share of Seller Common Stock outstanding, on an as-converted basis, and held by such holder as of immediately prior to the Effective Time equal to the difference of (A) the quotient of (1) the sum of (a) the Initial Merger Consideration plus (b) the Aggregate Vested Option Exercise Price divided by (2) the sum of (a) the number of outstanding shares of Seller Stock, on an as-converted basis, as of immediately prior to the Effective Time plus (b) the number of shares subject to outstanding Vested Options, as of immediately prior to the Effective Time (such amount in clause (A), the “Initial Per Common Share Payment”) minus (B) the product of (1) the sum of (A) the General Escrow Amount, (B) the Net Cash Escrow Amount, (C) the Tax Escrow Amount and (D) the Securityholders’ Representative Expense Fund multiplied by (2) the quotient of (a) Initial Per Common Share Payment divided by (b) the sum of (1) the Initial Merger Consideration plus (2) the Aggregate Vested Option Exercise Price (such amount in clause (B), the “Escrow Per Common Share Payment”); and

(ii) The holders of Vested Options shall be paid an amount per share of Seller Common Stock subject to holder’s Vested Options equal to the difference of (A) the difference of (1) the Initial Per Common Share Payment minus (2) the per share exercise price for such option (the “Initial Per Vested Option Amount”) minus (B) the product of (1) the sum of (A) the General Escrow Amount, (B) the Net Cash Escrow Amount, (C) the Tax Escrow Amount and (D) the Securityholders’ Representative Expense Fund multiplied by (2) the quotient of (a) the Initial Per Common Share Payment divided by (b) the sum of (1) the Initial Merger Consideration plus (2) the Aggregate Vested Option Exercise Price (such amount in clause (B), the “Escrow Per Vested Option Payment”).

(d) Upon the release of the General Escrow Amount, the Net Cash Escrow Amount, the Tax Escrow Amount or the Securityholders’ Representative Expense Fund pursuant to the terms of this Agreement and the Escrow Agreement, each Seller Securityholder will receive an amount in cash for each share of Seller Common Stock, each share of Seller Preferred Stock, on an as-converted basis, and each Vested Option held by such Seller Securityholder equal to the Escrow Per Common Share Payment or the Escrow Per Vested Option Payment, respectively; provided, however, that all or a portion of such distribution may be delayed (other than the Securityholders’ Representative Expense Fund), and the amount of the Escrow Per Common Share Payment or the Escrow Per Vested Option Payment, as applicable, may be reduced, pursuant to the provisions of this Agreement and the Escrow Agreement.

(e) All additional Merger Consideration shall be payable to the Seller Stockholders, on an as-converted basis, and the holders of Vested Options, on a fully exercised basis, in an amount per share of Seller Common Stock equal to the quotient of (A) the amount of such additional Merger Consideration divided by (B) the sum of (1) the number of outstanding

shares of Seller Stock, on an as converted basis, as of immediately prior to the Effective Time plus (2) the number of shares of Seller Common Stock subject to all outstanding Vested Options as of immediately prior to the Effective Time.

2.3 Escrow; General Escrow Amount; Net Cash Escrow Amount; Tax Escrow Amount; Securityholders’ Representative Expense Fund.

(a) Immediately following the Effective Time, Buyer shall deposit with Deutsche Bank Trust Company Americas (the “Escrow Agent”) (i) the General Escrow Amount to be retained in an interest-bearing escrow (the “General Escrow Account”), (ii) the Net Cash Escrow Amount to be retained in a separate interest-bearing escrow (the “Net Cash Escrow Account”) and (iii) the Tax Escrow Amount to be retained in a separate interest-bearing escrow (the “Tax Escrow Account”) in accordance with the terms of this Agreement and an Escrow Agreement, by and among Buyer, the Securityholders’ Representative and the Escrow Agent, in substantially the form attached hereto as Exhibit D (the “Escrow Agreement”). Immediately following the Effective Time, Buyer shall deposit with a bank designated by the Securityholders’ Representative the Securityholders’ Representative Expense Fund.

(b) The General Escrow Amount shall be used to satisfy amounts payable to Buyer or any of the other Buyer Indemnified Parties pursuant and subject to Article IX. The Net Cash Escrow Amount shall be used solely to satisfy amounts payable to Buyer pursuant to Section 2.4, subject to Article IX. The Tax Escrow Amount shall be used solely to satisfy amounts payable to Buyer pursuant to Section 6.13, subject to Article IX. The Securityholders’ Representative Expense Fund shall be used to pay or reimburse the Securityholders’ Representative for the costs and expenses it incurs under this Agreement and the Escrow Agreement. Any portion of the General Escrow Amount that is not necessary to satisfy any payment or unresolved bona fide claim pursuant to Article IX, shall be released within five (5) Business Days after the date that is eighteen (18) months following the Effective Time, and shall be delivered to the Seller Securityholders by the Escrow Agent, allocable to the Seller Securityholders as set forth on the Final Conversion Schedule, subject to the terms of the Escrow Agreement. Any portion of the Net Cash Escrow Amount that is not necessary to satisfy any payment to Buyer pursuant to Section 2.4, subject to Article IX, shall be released within five (5) Business Days after the final determination of the Net Cash Balance in accordance with Section 2.4(d), and shall be delivered to the Seller Securityholders by the Escrow Agent, allocable to the Seller Securityholders as set forth on the Final Conversion Schedule, subject to the terms of the Escrow Agreement. Any portion of the Tax Escrow Amount that is not necessary to satisfy any payment or unresolved bona fide claim pursuant to Section 6.13 to Buyer, subject to Article IX, shall be released within five (5) Business Days after the fourth (4^th) anniversary of the Closing Date, and shall be delivered to the Seller Securityholders by the Escrow Agent, allocable to the Seller Securityholders as set forth on the Final Conversion Schedule, subject to the terms of the Escrow Agreement. Any portion of the Securityholders’ Representative Expense Fund that is not necessary to satisfy any remaining costs or expenses of the Securityholders’ Representative under this Agreement and the Escrow Agreement shall be delivered to the Seller Securityholders by the Securityholders’ Representative in its sole discretion, allocable to the Seller Securityholders as set forth on the Final Conversion Schedule.

2.4 Merger Consideration Adjustments.

(a) For the purposes of this Agreement, the term “Net Cash Balance” means the difference of (A) the aggregate amount of cash and cash equivalents of Seller and its Subsidiaries minus (B) the aggregate amount of accounts payable and accrued expenses of Seller and its Subsidiaries (other than the Seller Transaction Expenses), calculated in accordance with GAAP and consistent with Seller’s past practices; provided that for purposes of the foregoing current Tax liabilities as of the Closing shall be included as accrued expenses of Seller, current Tax assets as of the Closing shall be included as cash and cash equivalents of Seller and deferred Tax liabilities and deferred Tax assets shall not be taken into account in such calculation.

(b) Not less than three (3) Business Days before the Closing Date, Seller shall deliver to Buyer an estimate of Net Cash Balance as of the Closing Date (the “Preliminary Net Cash Balance”), and which shall be reasonably acceptable to Buyer, as part of the Seller Schedule.

(i) if the Preliminary Net Cash Balance is negative, Buyer shall reduce the Closing Payment by an amount equal to the absolute value of the Preliminary Net Cash Balance (the “Preliminary Net Cash Deficit”); and

(ii) if the Preliminary Net Cash Balance is positive, Buyer shall increase the Closing Payment by an amount equal to the absolute value of the Preliminary Net Cash Balance (the “Preliminary Net Cash Surplus”).

(d) Within seventy-five (75) days after the Closing Date, Buyer shall deliver to the Securityholders’ Representative and the former Chief Financial Officer of the Seller a statement (“Buyer’s Statement”) setting forth Buyer’s determination of the Net Cash Balance as of the Closing Date, the amount of Final Seller Transaction Expenses and the amount of Final Indebtedness each as of the Closing Date, such determination to be made in accordance with GAAP. Within forty five (45) days of receipt of Buyer’s Statement, Buyer and the Securityholders’ Representative will either agree to accept the calculation of Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness as set forth on Buyer’s Statement or shall submit any dispute to an Arbitrating Accountant in accordance with Section 2.5 below. Once accepted by the parties or on the issuance of a determination by the independent accountant, the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness will be deemed final and binding on the parties.

(e) Within five (5) Business Days after the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness are deemed final as set forth in Section 2.4(d):

(i) if the Net Cash Balance is less than the Preliminary Net Cash Balance, Buyer shall deduct from the Net Cash Escrow Account an amount equal to the Preliminary Net Cash Balance minus the Net Cash Balance;

(ii) if the Net Cash Balance is more than the Preliminary Net Cash Balance, Buyer shall pay to the Payment Agent an amount equal to the Net Cash Balance minus the Preliminary Net Cash Balance to be distributed to the Seller Stockholders and holders of Vested Options as if it were additional Merger Consideration;

(iii) If the Seller Transaction Expense Adjustment is positive, the Buyer shall deduct from the Net Cash Escrow Account, an amount equal to the Seller Transaction Expense Adjustment;

(iv) If the Seller Transaction Expense Adjustment is negative, Buyer shall pay to the Payment Agent an amount equal to the Seller Transaction Expense Adjustment minus the amount to be distributed to the Seller Stockholders and holders of Vested Options as if it were additional Merger Consideration.

(v) If the Indebtedness Adjustment is positive, Buyer shall deduct from the Net Cash Escrow Account, an amount equal to the Indebtedness Adjustment;

(vi) If the Indebtedness Adjustment is negative, Buyer shall pay to the Payment Agent an amount equal to the Indebtedness Adjustment minus the amount to be distributed to the Seller Stockholders and holders of Vested Options as if it were additional Merger Consideration.

In the event that Buyer is entitled to deduct amounts from the Net Cash Escrow Account and the Buyer is required to make additional payments to the Seller Stockholders and holders of Vested Options pursuant to this Section 2.4(e), the amounts shall be offset against each other, and the net amount shall either be deducted from the Net Cash Escrow Account or be paid to the Seller Stockholders and holders of Vested Options depending upon which amount is greater.

Notwithstanding any other provision of this Agreement, subject to the limitations in Article IX, in the event that Buyer is entitled to deduct amounts from the Net Cash Escrow Account pursuant to this Section 2.4 in excess of the Net Cash Escrow Account, Buyer shall be entitled to deduct the entire Net Cash Escrow Amount from the Net Cash Escrow Account, and any additional owed amounts shall be deducted from the General Escrow Amount, and, after the General Escrow Amount has been exhausted, Buyer and the other Buyer Indemnified Parties shall not be entitled to any further amounts from any other source pursuant to this Agreement.

2.5 Submission of Dispute to an Independent Accountant. Disputes with respect to Buyer’s Statement shall be resolved as follows, subject to Article IX:

(a) The Securityholders’ Representative shall have sixty (60) days after receipt of Buyer’s Statement (the “Dispute Period”) to deliver to Buyer a written notice (a “Dispute Notice”) disputing any of the elements of or amounts reflected in the calculations of the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness as reflected on Buyer’s Statement, with specific reference to those items, amounts or calculations which the Securityholders’ Representative disputes and setting forth the Securityholders’ Representative’s calculation of the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness (the “Disputed Items”). If Buyer does not receive a Dispute Notice within the Dispute Period, Buyer’s Statement shall be deemed to have been accepted and agreed to by the Securityholders’

Representative in the form in which it was delivered to the Securityholders’ Representative, and shall be final and binding upon the parties hereto. Any Dispute Notice sent to Buyer by the Securityholders’ Representative within the Dispute Period shall set forth in reasonable detail the elements and calculations with which the Securityholders’ Representative disagree. The Securityholders’ Representative shall not amend, supplement or modify a Dispute Notice that has been delivered to Buyer after the end of the sixty (60) day period following delivery of the Buyer’s Statement to the Securityholders’ Representative. Any elements or calculations contained in Buyer’s Statement which are not disputed in the Dispute Notice shall be deemed to be accepted by the Securityholders’ Representative. For thirty (30) days after delivery of any such Dispute Notice, Buyer and the Securityholders’ Representative shall attempt to resolve such dispute and agree in writing upon the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness.

(b) If Buyer and the Securityholders’ Representative are unable to resolve the Disputed Items within the thirty (30) day period after Buyer’s receipt of a Dispute Notice, the Securityholders’ Representative and Buyer shall jointly engage Ernst & Young LLP as arbitrator (the “Arbitrating Accountant”). If Ernst & Young LLP is unable or unwilling to serve as Arbitrating Accountant, the Arbitrating Accountant shall be a nationally recognized accounting firm selected promptly by agreement of Buyer and the Securityholders’ Representative or, if they are unable to agree, by lot conducted jointly by Buyer’s accountant and the Securityholders’ Representative’s accountant (or an accountant selected by the Securityholders’ Representative) from among the remaining “Big Four” nationally-recognized accounting firms or any other mutually acceptable nationally-recognized accounting firm. Any Disputed Item shall only be deemed resolved if such resolution is set forth in a writing signed by Buyer and the Securityholders’ Representative and no other communication, oral or written, including by electronic mail, shall establish any such resolution. Neither Buyer nor the Securityholders’ Representative shall engage in any communication of any kind, whether oral or written, with the Arbitrating Accountant except in the presence (in person or telephonically) of the other such party, or, in the case of written communications (including electronic mail), without such other party simultaneously receiving a copy of any such communications. The Arbitrating Accountant’s sole function shall be to arbitrate each Disputed Item in accordance with the requirements and principles of Section 2.4. The Arbitrating Accountant shall allow Buyer and the Securityholders’ Representative to present their respective positions regarding the Disputed Items and shall thereafter as promptly as possible provide the parties hereto a written determination of each Disputed Item, and such written determination shall be final and binding upon the parties hereto, and judgment may be entered on the award. The Arbitrating Accountant may, at its discretion, conduct a conference concerning the Disputed Items, at which conference each party shall have the right to present additional documents, materials and other information and to have present its advisors, counsel and accountants. In connection with such process, there shall be no other hearings or any oral examinations, testimony, depositions, discovery or other similar proceedings. The Arbitrating Accountant shall address only the issues in dispute, shall make its decision solely on the basis of the evidence and position papers presented to it, and may not assign a value to any Disputed Item greater than the greatest value for such Disputed Item claimed by a party or less than the smallest value for such Disputed Item claimed by a party. The Arbitrating Accountant shall promptly, and in any event within sixty (60) calendar days after the date of its appointment, render its decision on the question in writing and finalize the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness. The Securityholders’

Representative and Buyer shall pay the portion of the fees and costs of the Arbitrating Accountant (“Arbitration Costs”), if any, determined by multiplying the amount of the Arbitration Costs by a fraction the numerator of which is (with respect to each party) (A) the positive difference between (1) the aggregate amount payable pursuant to Section 2.4(e) based on the submissions by such party to the Arbitrating Accountant on Buyer’s Statement or the Dispute Notice, as applicable and (2) the determination of the actual aggregate amount payable pursuant to Section 2.4(e) based on the determinations of the Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness made by the Arbitrating Accountant and the denominator of which is (B) the aggregate difference between each party’s submission of the amount payable pursuant to Section 2.4(e) based on such party’s submission of Net Cash Balance, Final Seller Transaction Expenses and Final Indebtedness as set forth on Buyer’s Statement or the Dispute Notice, as applicable. Upon final resolution of Net Cash Balance, Final Seller Transaction Expenses, Final Indebtedness and each Disputed Item, Buyer’s Statement shall be revised to reflect such resolution and the Arbitrating Accountant’s determination shall become binding on all parties.

2.6 Contingent Payments. In the event that Dr. Andrew T. Yang remains an employee of Buyer, the Surviving Corporation or any of Buyer’s Subsidiaries on each of the first (1st), second (2nd) and third (3rd) anniversaries of the Closing Date (each an “Anniversary Date”), within five (5) Business Days following each such Anniversary Date, Buyer shall pay to the Payment Agent an amount equal to $4,000,000 to be distributed by the Payment Agent to the Seller Stockholders and holders of Vested Options as additional Merger Consideration pursuant to Section 2.2(e) (each such payment a “Contingent Payment” and together, the “Contingent Payments”). Notwithstanding the foregoing, in the event that Dr. Andrew T. Yang’s employment with Buyer, the Surviving Corporation or any of Buyer’s Subsidiaries is terminated by Buyer, the Surviving Corporation or any of Buyer’s Subsidiaries, as applicable, other than for Cause (as defined in Dr. Andrew T. Yang’s offer letter with Seller, dated as of April 14, 2011), or upon his death or disability in any event at any time prior to the third Anniversary Date, the Buyer shall pay to the Payment Agent the amount of each subsequent Contingent Payment on each subsequent Anniversary Date that occurs after such a termination of employment or death or disability for distribution by the Payment Agent to the Seller Stockholders and holders of Vested Options as additional Merger Consideration. Once paid, any amounts paid under this Section 2.6 shall not be subject to recapture by any party nor shall any such amount to be paid be offset against any claims for indemnification under this Agreement.

2.7 Payment and Surrender of Evidence of Seller Securities; Payment Fund.

(a) Prior to the Effective Time, Buyer or Merger Sub shall designate Deutsche Bank Trust Company Americas or such other bank or trust company reasonably acceptable to Seller to act as payment agent in connection with the Merger (the “Payment Agent”). Subject to the terms of Section 2.3 and Section 2.8 hereof, at or prior to the Effective Time, Buyer will provide to and shall deposit in trust with, the Payment Agent, an amount in cash equal to the aggregate amount of Initial Merger Consideration payable to Seller Securityholders under this Agreement. Until used for that purpose, the funds shall be invested by the Payment Agent, as directed by Buyer, and in accordance with a Payment Agent Agreement between Buyer and the Payment Agent, in obligations of or guaranteed by the United States of America or obligations of an agency of the United States of America which are backed by the full faith and credit of the United States of America or in deposit accounts or certificates of deposit with commercial banks.

(b) As soon as reasonably practicable after the date hereof but in any event prior to the Effective Time, Buyer shall cause to be mailed or otherwise made available to each holder of record of outstanding Seller Securities that will be converted pursuant to Section 2.1 into the right to receive Merger Consideration, and who has signed a written stockholder consent or joinder and waiver agreement as part of the Stockholders’ Consent, a letter of transmittal in the form to be provided by Buyer (a “Letter of Transmittal”), such other documents as may reasonably be required by Buyer (including any required Form W-8 or W-9) and instructions for use in effecting such holder’s delivery of all Seller Stock and vested Seller Stock Options held by such holder to the Payment Agent in exchange for the right to receive the Merger Consideration in respect thereof as contemplated in Section 2.1. Promptly after the Effective Time, Buyer shall cause to be mailed or otherwise made available to each holder of record of outstanding Seller Securities, and who has not, immediately following the Effective Time, signed a written stockholder consent or joinder and waiver agreement as part of the Stockholders’ Consent, such other documents as may reasonably be required by Buyer (including any required Form W-8 or W-9) and instructions for use in effecting such holder’s delivery of such Seller Securities to the Payment Agent in exchange for the Merger Consideration in respect thereof as contemplated in Section 2.1. Until surrendered as contemplated by this Article II, from and after the Effective Time each certificate or other evidence that, immediately prior to the Effective Time, represented a Seller Security shall be deemed to represent only the right to receive its portion of the Merger Consideration determined pursuant to this Agreement then due and shall not evidence any interest in, or any right to exercise the rights of a stockholder or other security holder of Buyer or the Surviving Corporation or any other rights. Notwithstanding the foregoing, any surrendered certificate, notice of option grant or other evidence of ownership of a Seller Security that represents Dissenting Shares shall be returned to the Person surrendering such certificate or other evidence unless such Person waives all dissenters’ rights at or prior to such time. If the Merger Consideration is to be paid to a person other than the one in whose name such certificate or other evidence surrendered in exchange therefor is registered, it shall be a condition to such payment that such certificate or other evidence be properly endorsed (or accompanied by an appropriate instrument of transfer) and accompanied by evidence that any applicable stock or other security transfer taxes and other applicable taxes have been paid or provided for.

(c) The Payment Agent and Buyer, as the case may be, shall not be obligated to deliver cash to which a holder of Seller Securities would otherwise be entitled as a result of the Merger until such holder surrenders the certificate or certificates or notice of option grants or other evidence of ownership, as the case may be, representing the shares of Seller Securities for exchange as provided in this Section 2.7, or, executes an appropriate affidavit of loss and indemnity agreement (without a bond requirement posting).

(d) Attached as Schedule 2.7(d) is a schedule (the “Preliminary Conversion Schedule”) showing as of the date hereof (i) the name of each Seller Stockholder and the number, class and series of shares of Seller Stock held by each such Seller Stockholder; (ii) the name of each holder of Vested Options and the number of shares of Seller Common Stock subject to each Vested Option held by each such holder of Vested Options and the exercise price per share; and (iii) a calculation of (A) the aggregate amount of Initial Per Common Share

Payments and Escrow Per Common Share Payments (assuming no claims for Damages) payable to each Seller Securityholder pursuant to Section 2.2 and (B) the aggregate amount of Initial Per Vested Option Amounts and Escrow Per Vested Option Payments payable to each holder of Vested Options in respect of all Vested Options held by such holder. No later than two (2) Business Days prior to the expected Closing Date, Seller shall deliver to Buyer a schedule (the “Final Conversion Schedule”) showing, as of the Closing Date, (i) the name of each Seller Stockholder and the number, class and series of shares of Seller Stock held by each such Seller Stockholder; (ii) the name of each holder of Vested Options and the number of shares of Seller Common Stock subject to each Vested Option held by each such holder of Vested Options and the exercise price per share; (iii) a calculation of (A) the aggregate amount of Initial Per Common Share Payments and Escrow Per Common Share Payments (assuming no claims for Damages) payable to each Seller Securityholder pursuant to Section 2.2 and (B) the aggregate amount of Initial Per Vested Option Amounts and Escrow Per Vested Option Payments payable to each holder of Vested Options in respect of all Vested Options held by such holder and (iv) the amounts to be withheld from the Merger Consideration to which each Seller Securityholder is entitled, including the type and amount of each Tax to be withheld from each Seller Securityholder. The chief executive officer and the chief financial officer of Seller shall certify that the Final Conversion Schedule correctly reflects the calculations required to be made pursuant to this Agreement, and Seller shall deliver the Final Conversion Schedule together with such certification to Buyer at Closing.

(e) At any time which is more than twelve (12) months after the Effective Time, Buyer shall be entitled to require the Payment Agent to deliver to it any funds which had been deposited with the Payment Agent and have not been disbursed in accordance with this Article II (including, without limitation, interest and other income received by the Payment Agent in respect of the funds made available to it), and after the funds have been delivered to Buyer, Seller Securityholders entitled to payment in accordance with this Article II shall be entitled to look solely to Buyer (subject to abandoned property, escheat or other similar applicable Laws) for payment of the Merger Consideration upon surrender of the certificates or other evidence of ownership of a Seller Security held by them, without any interest thereon. Any Merger Consideration remaining unclaimed as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable Law, become the property of Buyer free and clear of any claims or interest of any person previously entitled thereto.

(f) Notwithstanding anything to the contrary in this Article II, none of the Payment Agent, Buyer, the Surviving Corporation or any party hereto or agent thereof shall be liable to any Person in respect of any cash delivered to a public official as required by any applicable abandoned property, escheat or similar Law.

2.8 Appraisal Rights.

(a) Notwithstanding anything in this Agreement to the contrary, any shares (the “Dissenting Shares”) of the Seller Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Seller Stockholders who, in accordance with Section 262 of the DGCL or Chapter 13 of the California Corporations Code (the “Appraisal Rights Provisions”), (i) have not voted in favor of adopting this Agreement, (ii)

shall have demanded properly in writing appraisal for such shares, (iii) have otherwise complied in all respects with the Appraisal Rights Provisions, and (iv) have not effectively withdrawn, lost, or failed to perfect their rights to appraisal (the “Dissenting Stockholders”), will not be converted into Merger Consideration, but at the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, shall be cancelled and shall cease to exist and shall represent the right to receive only those rights provided under the Appraisal Rights Provisions.

(b) Seller shall give Buyer and Merger Sub prompt notice of any demands received by Seller for the exercise of appraisal rights with respect to shares of Seller Stock and Buyer shall have the right to participate in all negotiations and proceedings with respect to such demands. Seller shall not, except with the prior written consent of Buyer, which consent shall not be unreasonably withheld, make any payment with respect to, or settle or offer to settle, any such demands.

2.9 Performance Awards. In connection with the Merger, not more than five (5) Business Days prior to and effective on the Closing Date, Buyer and Buyer’s Board of Directors or designated committee shall grant to the employees of Seller or its Subsidiaries listed on Schedule 2.9 hereto, awards of restricted stock units with respect to Buyer Common Stock, each such award to cover a number of shares of Buyer Common Stock determined by dividing (i) the value set forth opposite the employee’s name on Schedule 2.9 (which shall be in preliminary form on the date of this Agreement and in final form prior to Closing) (the aggregate value of all such awards to equal $13 million) by (ii) the volume weighted-average closing price per share of Buyer Common Stock on Nasdaq for the fifteen (15) trading days prior to the Closing Date, and each such award to vest and be paid in accordance with the achievement by the Surviving Corporation of certain non-GAAP revenue and operating income criteria for each of the three (3) full fiscal year periods beginning on January 1, 2012, as mutually agreed to by Buyer and Seller’s Chief Executive Officer prior to Closing in accordance with and subject to the terms and conditions of Buyer’s Fourth Amended and Restated 1996 Stock Option and Incentive Plan and the applicable award agreement (the “Performance Awards”). To be eligible for such awards, each employee must enter into an IP Protection Agreement. Except as set forth above or in an offer letter executed in connection with the transactions contemplated hereby, the other terms and conditions of the Performance Awards shall be the same as the standard terms and conditions applicable to grants of restricted stock units made by Buyer to its employees.

2.10 Employee Incentive Bonus. In each of the three (3) full fiscal years beginning on January 1, 2012, the Seller Continuing Employees shall be eligible to receive an annual incentive bonus (the “Employee Incentive Bonus”), based on the achievement by the Surviving Corporation of certain non-GAAP revenue, operating income and technology milestone criteria, as mutually agreed to by Buyer and the Seller’s Chief Executive Officer prior to Closing, and as subsequently modified by the Buyer and Dr. Yang, in an aggregate amount equal to ten percent (10%) of the aggregate base salaries of such Seller Continuing Employees who are then employed by Buyer, the Surviving Corporation or one of their Subsidiaries for such fiscal year. The individual amounts of the Employee Incentive Bonus for each Seller Continuing Employee shall be mutually agreed to by Buyer’s and Seller’s Chief Executive Officers. The final aggregate amount of such Employee Incentive Bonuses is subject to approval by the Buyer’s Board of Directors or a committee thereof. Except as set forth in an offer letter executed in

connection with the transactions contemplated hereby, the payment of an Employee Incentive Bonus to any Seller Continuing Employee shall be subject to the same terms and conditions as incentive bonuses are payable to Buyer’s employees.

2.11 Withholding Rights. Buyer, Seller and the Surviving Corporation shall be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement such amounts as are required to deduct and withheld under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the persons receiving the amounts otherwise payable pursuant to this Agreement in respect of which such deduction and withholding was made.

Without limiting the generality of the foregoing, during the Pre-Closing Period, except as set forth in Section 5.1 of the Seller Disclosure Schedule or as required by Law, Seller shall not do, cause or permit, and shall cause its Subsidiaries not to do, cause or permit, any of the following actions, without the prior written consent of Buyer, in its sole discretion (including, without limitation, e-mail notification by the individuals named in Section 3.28 or Section 4.7, as applicable), except as expressly provided or permitted in this Agreement:

(q) enter, modify, or terminate any Lease, or take any action under any of the Leased Real Property not otherwise required to be taken pursuant to the terms of the Leases; provided that, Seller shall promptly notify Buyer of, and furnish Buyer with information relating to, any actual or threatened breach of any material term of any such lease or sublease upon Seller having actual knowledge of such actual or threatened breach;

(a) During the Pre-Closing Period, Seller shall take all action necessary in accordance with this Agreement, the DGCL, the California Corporations Code and the Seller Charter and Seller Bylaws to obtain the Stockholders’ Consent via written consent immediately (but subject to applicable Law, including any minimum notice period required thereby) following the execution hereof. Seller’s obligation to seek the Stockholders’ Consent in accordance with this Section 6.1(a) shall not be limited to or otherwise affected by the commencement, disclosure, announcement or submission to Seller of any Acquisition Proposal.

(a) During the Pre-Closing Period, Seller will prepare an information statement in form and substance reasonably acceptable to Buyer (the “Information Statement”)

relating to this Agreement, the Merger and the other transactions contemplated hereby. Seller shall ensure that the information in the Information Statement (i) will 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 are made, not misleading and (ii) complies with applicable Law; provided, however, that Seller makes no representation in this Section 6.2 with respect to any information provided by Buyer or its Representatives for inclusion in the Information Statement. Buyer shall ensure that the information provided by Buyer or its Representatives for inclusion in the Information Statement (i) will not contain any untrue statement of 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 are made, not misleading, and (ii) complies with applicable Law. The Information Statement shall include the unanimous recommendation of the Board of Directors of Seller in favor of this Agreement and the Merger and the conclusion of the Board of Directors of Seller that the Merger is advisable and in the best interests of the Seller Stockholders.

(b) Promptly after the date hereof, and in no case later than the Closing, Seller shall deliver (in any manner permitted by applicable Law) to each Seller Stockholder the Information Statement and notice of the Seller Stockholders’ approval and adoption of this Agreement and the consummation of the transactions contemplated hereby, together with the notice of dissenters’ rights required pursuant to the DGCL and the California Corporations Code, to Seller Stockholders who may elect dissenters’ rights under such law. Thereafter, subject to Section 2.9, Seller shall deliver by any manner permitted by the DGCL and the California Corporations Code any subsequent notice required to be delivered with respect to Dissenting Shares pursuant to the DGCL and the California Corporations Code.

6.3 Third Party Consents and Regulatory Approvals.

(a) Subject to the terms hereof, during the Pre-Closing Period, Seller and Buyer shall use their reasonable best efforts to:

(i) take, or cause to be taken, all actions, and do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper, or advisable to consummate and make effective the transactions contemplated hereby (including, without limitation, the Merger) as promptly as practicable;

(ii) as promptly as practicable, obtain from any Governmental Authority or any other third party any consents, licenses, permits, waivers, approvals, authorizations, or orders required to be obtained or made by Seller or Buyer or any of their respective Subsidiaries in connection with the authorization, execution, and delivery of this Agreement and the consummation of the transactions contemplated hereby (including, without limitation, the Merger);

(iii) as promptly as practicable, make all necessary filings, and thereafter make any other required submissions, with respect to this Agreement and the Merger required under (A) the Exchange Act and any other applicable federal or state securities laws, (B) the HSR Act and any related governmental request thereunder, and (C) any other applicable Law; and

(iv) execute or deliver any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement (including, without limitation, the Merger).

Seller and Buyer shall cooperate with each other in connection with the making of all such filings, including providing copies of all such documents to the non-filing party and its advisors prior to filing and, if requested, accepting reasonable additions, deletions or changes suggested in connection therewith. Seller and Buyer shall use their respective reasonable best efforts to furnish to each other all information required for any application or other filing to be made pursuant to the rules and regulations of any applicable Law in connection with the transactions contemplated by this Agreement. For the avoidance of doubt, Buyer and Seller agree that nothing contained in this Section 6.3(a) shall modify or affect their respective rights and responsibilities under Section 6.2(b).

(b) During the Pre-Closing Period, Seller and Buyer shall use reasonable best efforts to obtain the authorizations, consents, orders and approvals and to make filings from or with any Governmental Authority or other third party necessary for their execution and delivery of, and the performance of their respective obligations pursuant to, this Agreement. The parties hereto will not take any action that will have the effect of delaying, impairing or impeding the receipt of any required approvals and shall promptly respond to any requests for additional information from any Governmental Authority. Each of Seller and Buyer hereby covenants and agrees to use its reasonable best efforts to secure termination of any waiting periods under the HSR Act and any other federal, state or foreign law, regulation, or decree designed to prohibit, restrict, or regulate actions for the purpose or effect of monopolization or restraint of trade (collectively, “Antitrust Laws”) and to obtain the approval of the Federal Trade Commission, the Antitrust Division of the United States Department of Justice or any other applicable Governmental Authority, for the Merger and the other transactions contemplated hereby. Notwithstanding the foregoing, nothing herein shall require Buyer or Seller, in connection with the receipt of any regulatory approval, to divest, sell, lease, license, hold separate, restrict or otherwise dispose of, or agree to divest, sell, lease, license, hold separate, restrict or otherwise dispose of any business whatsoever conducted by or proposed to be conducted by or any assets whatsoever of Buyer, Seller or any of their respective Subsidiaries, or to litigate or formally contest any proceedings relating to any regulatory approval process in connection with the Merger.

(c) During the Pre-Closing Period, Buyer and Seller will (i) promptly notify the other party of any written or oral communication to that party or its Affiliates from any Governmental Authority and, subject to applicable Law (including Regulations, codes, plans, Orders and charges thereunder), permit the other party to review in advance any proposed written communication to any Governmental Authority, in each case concerning the review, clearance or approval of any of the transactions contemplated hereby under the HSR Act or any similar applicable foreign Laws; (ii) not agree to participate, or to permit its Affiliates to participate, in any substantive meeting or discussion with any Governmental Authority in respect of any filings, investigation or inquiry concerning the review, clearance or approval of any of the

transactions contemplated hereby under the HSR Act or any similar applicable foreign Laws unless it consults with the other party in advance and, to the extent permitted by such Governmental Authority, gives the other party or its counsel the opportunity to attend and participate in such meeting; provided that if the Governmental Authority or applicable Law (including Regulations, codes, plans, Orders and charges thereunder) does not permit such participation by the other party or its counsel, or if Buyer’s and Seller’s respective counsels both agree in good faith that participation of Seller or Seller’s counsel would not be advisable, Buyer meeting with such Governmental Authority may proceed without the participation of Seller or its counsel; and (iii) furnish the other party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) drafted by or in conjunction with outside counsel between it and its Affiliates and its respective Representatives on the one hand, and any Governmental Authority or members of such Governmental Authority’s staff on the other hand, concerning the review, clearance or approval of any of the transactions contemplated hereby under the HSR Act or any similar applicable foreign Law, except to the extent prohibited by applicable Law (including Regulations, codes, plans, Orders and charges thereunder) or the instructions of such Governmental Authority.

(d) During the Pre-Closing Period, Buyer and Seller shall furnish to each other all information required for any application or other filing under the rules and regulations of any applicable Law in connection with the transactions contemplated by this Agreement.

(e) Buyer shall pay all filing and related fees in connection with any such filings that must be paid to any Governmental Authorities by any of the parties.

(f) During the Pre-Closing Period, each of Seller and Buyer shall give (or shall cause their respective Subsidiaries to give) any notices to third parties, and use, and cause their respective Subsidiaries to use, their reasonable best efforts to obtain any third party consents required in connection with the Merger that are (i) necessary to consummate the transactions contemplated hereby, (ii) disclosed or required to be disclosed in the Seller Disclosure Schedule or the Buyer Disclosure Schedule, as the case may be, or (iii) required to prevent the occurrence of an event that is reasonably likely to have a Seller Material Adverse Effect prior to or after the Effective Time, it being understood that neither Seller nor Buyer shall be required to make any payments in connection with the fulfillment of its obligations under this Section 6.3.

6.4 No Solicitation of Transactions; Acquisition Proposals.

(a) During the Pre-Closing Period, Seller agrees that, except as permitted by this Section 6.4, neither it nor any of its Subsidiaries nor any of the officers and directors of it or its Subsidiaries shall, and that it shall instruct and cause its and its Subsidiaries’ Representatives not to, directly or indirectly:

(i) initiate, solicit or knowingly encourage any inquiries or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, any Acquisition Proposal;

(ii) engage in, continue or otherwise participate in any discussions or negotiations regarding, or provide any non-public information or data to any Person relating to, any Acquisition Proposal; or

(iii) otherwise facilitate any effort or attempt to make an Acquisition Proposal.

(b) During the Pre-Closing Period, as promptly as practicable, and in any event within twenty-four (24) hours, after any officer or director of Seller receives any Acquisition Proposal, Seller shall provide Buyer with oral and written notice of the material terms and conditions of such Acquisition Proposal, request or inquiry, including (i) the identity of the Person or group making any such Acquisition Proposal, request or inquiry, (ii) a copy of all written materials provided by such Person in connection with such Acquisition Proposal, request or inquiry and (iii) a written summary, if it is not in writing, of any such Acquisition Proposal, request or inquiry. After receipt of the Acquisition Proposal, request or inquiry, during the Pre-Closing Period, Seller shall continue to keep Buyer promptly informed (in any event on a daily basis) of the status and details of any such Acquisition Proposal, request or inquiry (including, but not limited to, notice of all material amendments or developments with respect thereto). During the Pre-Closing Period, Seller shall provide Buyer with two (2) Business Days’ prior notice (or such lesser prior notice as is provided to the members of Board of Directors of Seller) of any meeting of the Board of Directors of Seller at which such Board of Directors of Seller is reasonably expected to discuss any Acquisition Proposal or any Change of Recommendation.

(c) If, prior to the time Stockholders’ Consent is obtained and during the Pre-Closing Period, Seller receives from a Person a bona fide written Acquisition Proposal, Seller may (A) provide information in response to a request therefor by such Person if Seller receives from the Person so requesting such information an executed confidentiality agreement on terms no more favorable to such Person as the terms of the Confidentiality Agreement; provided that, contemporaneously with furnishing any such non-public information to such Person, Seller furnishes to Buyer all such non-public information not previously provided to Buyer or (B) engage in discussions or negotiations with such Person, if prior to taking any action described in clause (A) or (B) above, the Board of Directors of Seller, after consultation with its outside legal counsel and financial advisors, determines in good faith that the failure to take any action described in clause (A) or (B) above would be inconsistent with its fiduciary obligations under applicable Law, and the Board of Directors of Seller believes in good faith, after consultation with its outside legal counsel and its financial advisors, that the Acquisition Proposal in respect of which such action is to be taken, if consummated, is or could reasonably be expected to lead to a Superior Proposal.

(d) During the Pre-Closing Period, the Board of Directors of Seller and each committee thereof shall not:

(i) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify or make any statement with the substantive effect of withholding, withdrawing, qualifying or modifying), in a manner adverse to Buyer (any such action, a “Change of Recommendation”), the Seller Recommendation unless the Board of Directors of Seller is entitled to take the actions specified under Section 6.4(e);

(ii) approve, recommend or declare advisable (publicly or otherwise) an Acquisition Proposal unless the Board of Directors has made a Change of Recommendation; or

(iii) except as expressly permitted by, and after compliance with, Section 8.1(d), cause or permit Seller to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (other than a confidentiality agreement entered into in compliance with Section 6.4(c)) relating to any Acquisition Proposal.

(e) Notwithstanding anything to the contrary set forth in this Agreement, prior to the receipt of the Stockholders’ Consent, the Board of Directors of Seller may, in response to a Superior Proposal that did not result from a breach by Seller of this Section 6.4, withhold, withdraw or modify its recommendation with respect to the Seller Recommendation or approve or recommend any Acquisition Proposal if the Board of Directors of Seller determines in good faith, after consultation with its outside legal counsel, that failure to do so would be inconsistent with its fiduciary obligations under applicable Law, but only on or after the seventh (7th) Business Day following Buyer’s receipt of written notice advising Buyer that the Board of Directors of Seller desires to withhold, withdraw or modify the recommendation due to the existence of a Superior Proposal, specifying the material terms and conditions of such Superior Proposal (including any material changes) and identifying the person making such Superior Proposal. Such seven (7) Business Day period shall be required for each and every Superior Proposal or material modification thereto, as applicable.

(f) Nothing contained in this Section 6.4 shall be deemed to prohibit Seller from complying with its disclosure obligations under U.S. federal or state Law with regard to an Acquisition Proposal; provided, however, that if such disclosure has the substantive effect of withdrawing or adversely modifying the Seller Recommendation in any respect, such disclosure shall be deemed to be a Change of Recommendation and Buyer shall have the right to terminate this Agreement as set forth in Section 8.1(e).

(g) Seller agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposal. Seller agrees that it will take the necessary steps to promptly inform the individuals or entities referred to in the first sentence hereof of the obligations undertaken in this Section 6.4 and in the Confidentiality Agreement.

6.5 Access to Information.

(a) Upon reasonable prior notice during the Pre-Closing Period and subject to applicable Laws relating to the premerger exchange of information, Seller, shall, and shall cause each of its Subsidiaries to, afford to the officers, employees, accountants, counsel, and other Representatives of Buyer, reasonable access without undue interruption, during normal business

hours during the period from the date of this Agreement until the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, to all of its properties, books, contracts, commitments, and records (other than confidential information contained in personnel files to the extent the disclosure of such information is prohibited by privacy laws or other confidential information per the terms of nondisclosure or similar agreements). Upon reasonable prior notice during the Pre-Closing Period and subject to applicable Laws relating to the premerger exchange of information, Seller also shall provide Buyer with reasonable access to Seller’s officers, employees, agents, customers and suppliers. Neither Seller nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would contravene any Law, rule, regulation, order, judgment, decree, or binding agreement entered into prior to the date of this Agreement or would reasonably be expected to violate or result in a loss or impairment of any attorney-client or work product privilege or would violate or prejudice the rights of third parties. The parties hereto will use commercially reasonably efforts to make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Notwithstanding the foregoing, Buyer shall not, without the consent of Seller (which consent shall not be unreasonably withheld, conditioned or delayed), contact any customers, suppliers or key Seller Employees.

(b) With respect to all information furnished by one party to the other party or its Representatives under this Agreement, the parties shall comply with, and shall cause their respective Representatives to comply with, all of their respective obligations under the Confidentiality Agreement. Notwithstanding anything to the contrary contained in this Section 6.5, Seller shall not be obligated, and shall not be obligated to cause any of its Subsidiaries, to afford to Buyer or its Representatives any access to any of its properties, books, contracts, commitments, and records relating to, or in respect of, competitively sensitive information, the sharing of which would violate applicable Laws relating to the premerger exchange of information.

6.6 Employment and Benefit Matters.

(a) Benefits. From the Effective Time through December 31, 2011, Seller Employees will be entitled to participate in the Seller Employee Programs (other than Seller equity-based plans) on the same terms as those in effect immediately prior to the Effective Time. Following January 1, 2012, the employees of the Surviving Corporation and its Subsidiaries who were employed by the Seller or its Subsidiaries as of the Effective Time and who remain employed on or after January 1, 2012 (the “Surviving Corporation Employees”) will be entitled to participate in either (i) the Seller Employee Programs (other than Seller equity-based plans) on the same terms, or terms which in the aggregate provide substantially comparable benefits, as those in effect immediately prior to the Effective Time, (ii) the employee benefit plans of Buyer and its Subsidiaries on the same terms as similarly-situated employees of Buyer and its Subsidiaries or (iii) a combination of (i) and (ii), and in each case in the discretion of Buyer, and Buyer may terminate any of the Seller Employee Programs or merge any of the Seller Employee Programs with Buyer’s employee benefit plans as Buyer deems appropriate, in each case subject to the terms of such Seller Employee Program and this Agreement. Subject to the requirements of applicable Law and unless such recognition of service would result in a duplication of benefits, Buyer shall, and shall cause the Surviving Corporation or another Affiliate of Buyer to, treat, and cause the applicable benefit plans to treat, the service of Surviving Corporation

Employees with Seller or its Subsidiaries attributable to any period before the Effective Time as service rendered to Buyer or the Surviving Corporation for all purposes, including, but not limited to, eligibility to participate, vesting, including, but not limited to, applicability of any minimum waiting periods for participation, excluding for these purposes benefit accrual under any defined benefit plan. Without limiting the foregoing, Buyer shall not, and shall cause the Surviving Corporation not to, treat any Surviving Corporation Employee as a “new” employee for purposes of any exclusions under any health or similar plan of Buyer or the Surviving Corporation for a pre-existing medical condition, except to the extent such exclusions were applicable under a Seller Employee Program immediately prior to the Effective Time.

(b) “At Will” Employment. The Seller Employees who remain employed after the Effective Time shall be considered to be employed by Buyer “at will” and nothing in this Agreement shall be construed to limit the ability of Buyer or the Surviving Corporation to terminate the employment of any such Seller Employee at any time. Notwithstanding anything in this Agreement to the contrary, Buyer shall, or shall cause the Surviving Corporation or relevant Subsidiary or another Affiliate of Buyer to, assume and honor in accordance with their terms all deferred compensation plans, agreements and arrangements, severance and separation pay plans, agreements and arrangements, and written employment, severance, retention, incentive, change in control and termination agreements (including any change in control provisions therein) set forth in Section 6.6(b) of the Seller Disclosure Schedule applicable to employees of Seller or a Seller Subsidiary, in the same manner and to the same extent that Seller or a Seller Subsidiary would be required to perform and honor such plans, agreements and arrangements if the transactions contemplated by this Agreement had not been consummated.

(c) Continuation of Employment. No provision of this Section 6.6 shall create any third-party beneficiary rights in any employee or former employee (including any beneficiary or dependent thereof) of Seller or any Subsidiary of Seller in respect of continued employment (or resumed employment) with Buyer, the Surviving Corporation or any of Buyer’s Subsidiaries and no provision of this Section 6.6 shall create such rights in any such persons in respect of any benefits that may be provided, directly or indirectly, under any employee program or any plan or arrangement that may be established by Buyer or any of its Subsidiaries. No provision of this Agreement shall constitute a limitation on the rights to amend, modify or terminate after the Effective Time any such plans or arrangements of Buyer or any of its Subsidiaries, provided such amendment, modification or termination is effected in accordance with applicable Law and such underlying plan or arrangement. Notwithstanding the foregoing, Buyer agrees that during the calendar year ending December 31, 2011 it will not decrease the amount of base salary payable to any Seller Employee and will not amend or decrease the amounts payable to any Seller Employee under Seller’s 2011 Executive Bonus Program, 2011 Sales Compensation Policy, 2011 AE Compensation Policy and all other compensation plans set forth on Schedule 6.6(c), so long as such Seller Employee remains employed by Buyer, the Surviving Corporation or any of their Subsidiaries during such period.

6.7 Directors’ and Officers’ Indemnification and Insurance.

(a) Buyer and Merger Sub agree that all rights to indemnification, reimbursement, contribution, advancement of expenses or exculpation now existing in favor of, and all limitations on the personal liability of each present and former director, officer,

employee, fiduciary, or agent of Seller and its Subsidiaries and all other covered persons provided for in the respective organizational documents, in effect as of the date hereof, shall continue to be honored and in full force and effect for a period of six (6) years after the Effective Time (and if any statute is amended to provide for benefits that are more favourable to such Persons, then such Persons shall be entitled to the benefits of such amendment); provided, however, that all rights to indemnification, reimbursement, contribution, advancement of expenses or exculpation in respect of any claims asserted or made within such period shall continue until the disposition of such claim. During such period, Buyer shall not directly or indirectly through the Surviving Corporation or otherwise, amend, repeal or otherwise modify such provisions for indemnification, reimbursement, contribution, advancement of expenses or exculpation in any manner that would adversely affect the rights thereunder of individuals who at any time at or prior to the Effective Time was a director, officer, employee, fiduciary, or agent of Seller and its Subsidiaries or any other covered person in respect of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement), unless such modification is required by law. In addition, from and after the Effective Time, Buyer and Surviving Corporation shall indemnify and hold harmless the present and former officers and directors of Seller and its Subsidiaries and all other covered persons pursuant to, and otherwise comply with, the terms of the written indemnification agreements between Seller and/or one or more of its Subsidiaries and such officers and directors and listed in Section 6.7 of the Seller Disclosure Schedule.

(b) The certificates of incorporation, bylaws or other organizational documents of the Surviving Corporation and each of its Subsidiaries shall contain the provisions with respect to indemnification, reimbursement, advancement of expenses, contribution and exculpation from liability set forth in the Seller’s Certificate of Incorporation and the Seller’s Bylaws or other organizational documents or such Subsidiary’s organizational documents, as the case may be, on the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six years after the Closing in any manner that would adversely affect the rights thereunder of any covered person, except as required by Law (and if any statute is amended to provide for benefits that are more favourable to the covered persons, then each covered person shall be entitled to the benefits of such amendment).

(c) At or prior to the Effective Time, Seller shall purchase a “tail” directors’ and officers’ liability insurance policy (which by its terms shall survive the Merger) for its directors and officers, which shall provide such directors and officers with coverage for six (6) years following the Effective Time of not less than the existing coverage under, and have other terms not materially less favorable on the whole to, the insured persons than the directors’ and officers’ liability insurance coverage presently maintained by Seller. Buyer shall, and shall cause the Surviving Corporation to, maintain such policy in full force and effect, and continue to honor the obligations thereunder.

(d) If Buyer, Merger Sub or the Surviving Corporation merges into, consolidates with or transfers all or substantially all of its assets to another Person or liquidates, dissolves or winds up its operations, then and in each such case, Buyer, Merger Sub and/or the Surviving Corporation, as the case may be, shall make proper provision so that the surviving or resulting entity or the transferee in such transaction assumes the obligations of Buyer, Merger Sub and/or the Surviving Corporation under this Section 6.7.

(e) The obligations under this Section 6.7 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.7 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.7 applies shall be third party beneficiaries of this Section 6.7 and shall be entitled to enforce the covenants contained herein).

6.8 Publicity. Except with respect to any action taken pursuant to, and in accordance with, Section 6.4, so long as this Agreement is in effect, neither Buyer nor Seller shall, or shall permit any of its respective Subsidiaries to, issue or cause the publication of any press release or other public announcement with respect to, or otherwise make any public statement concerning, the transactions contemplated by this Agreement without the consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed, except as may be required by applicable Law or the applicable rules of any stock exchange, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other parties reasonable time to comment on such release or announcement in advance of such issuance. Upon the execution of this Agreement and at the Closing, Buyer and Seller shall issue a mutually agreed upon press release announcing the transactions contemplated hereby. Notwithstanding anything to the contrary in this Section 6.8, Seller and its Representatives shall be permitted to make statements or communications to the holders of Seller Securities or to members of the board of directors of the Seller or advisors with a need to know the information contained in such statements or communications without the consent of Buyer, and to counterparties to contracts, customers of the Seller and its Subsidiaries and suppliers of the Seller and its Subsidiaries with a need to know the information contained in such statements or communications after reasonable consultation with Buyer and with the consent of Buyer, such consent not to be unreasonably withheld, conditioned or delayed.

6.9 Notification of Certain Events. During the Pre-Closing Period, each of Seller and Buyer will give prompt notice to the other of (i) any notice or other communication from any person alleging that the consent of such person is or may be required in connection with the Merger or any of the other transactions contemplated by this Agreement, (ii) any notice or other communication from any Governmental Authority in connection with the Merger or any of the other transactions contemplated by this Agreement or (iii) any litigation relating to, involving or otherwise affecting Seller, Buyer, Merger Sub or any of their respective Subsidiaries that relates to the Merger or any of the other transactions contemplated by this Agreement. During the Pre-Closing Period, Seller shall give prompt written notice to Buyer of the occurrence of any event that is likely to cause any representation or warranty made by it contained in this Agreement to be untrue or inaccurate at or prior to Closing, or any failure of Seller to comply with or satisfy

any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. During the Pre-Closing Period, Buyer shall give prompt written notice to Seller of any representation or warranty made by it or Merger Sub contained in this Agreement becoming untrue or inaccurate in any material respect, or any failure of Buyer or Merger Sub to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

6.10 Takeover Statutes. During the Pre-Closing Period, if any anti-takeover, control share acquisition, fair price, moratorium or other similar statute is or may become applicable to the Merger or the other transactions contemplated by this Agreement, each of Buyer and Seller and their respective Boards of Directors shall grant such approvals and take such lawful actions as are necessary to ensure that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute and any regulations promulgated thereunder on such transactions.

6.11 Continuation of Employment Letters.

(a) Prior to the Closing, Buyer shall request that each of the employees of Seller or its Subsidiaries mutually agreed upon by Buyer’s and Seller’s Chief Executive Officers prior to Closing sign a continuation of employment letter, in a form substantially similar to the Key Employee Letters and reasonably acceptable to Buyer indicating their intent to remain employed by the Surviving Corporation and outlining the expected terms of such employment arrangements. During the Pre-Closing Period, Seller shall use its commercially reasonable best efforts to assist Buyer in obtaining executed copies of such letters, and any restrictive covenant and assignment agreement that the Buyer determines is reasonably necessary and lawful to protect its interests, from such employees prior to Closing. Between the signing of this Agreement and the Closing Date, Buyer and Seller shall cooperate in good faith to satisfy any obligation under any labor law that covers employees of Seller or its Subsidiaries who are located outside the United States and is triggered by the signing of this Agreement or the consummation of the transactions contemplated hereby.

(b) Subject to the other provisions of this Agreement (including, without limitation, the final sentence of Section 6.6(c)), applicable Law, and continuation of employment letters, offer letters and agreements in effect following the Closing, Buyer and its Subsidiaries shall have the right to determine the compensation and employee benefits of the employees of Seller and its Subsidiaries following the Closing. Notwithstanding anything contained in this Agreement, but subject to applicable Laws, continuation of employment letters, offer letters and agreements in effect following the Closing, Buyer and its Subsidiaries shall have the right to terminate the employment of the employees of Seller and its Subsidiaries after the Closing.

6.12 Other Actions by the Parties. During the Pre-Closing Period, Buyer and Seller, at the request of the other party, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary or desirable for effecting

completely the consummation of this Agreement and the transactions contemplated hereby (including all action reasonably necessary to seek and obtain any and all approvals of any Governmental Authority or other Person required in connection with the Merger; provided, however, that neither Buyer nor (unless approved and so directed by Buyer in advance) Seller shall be obligated to make or consent to any divestiture or operational limitation or activity in connection therewith, or any waiver or modification of any right, or any payment of money or grant of any other commercial concession as a condition to obtaining any such approval). During the Pre-Closing Period, each party agrees to use commercially reasonable best efforts to cause the conditions set forth in Article VII to be satisfied, where the satisfaction of such conditions depends on action or forbearance from action by such party.

6.13 Taxes.

(a) The Seller Securityholders, severally and not jointly, as set forth in, and subject to Article IX, and in accordance with their pro rata share of the Merger Consideration in relation to all other Seller Securityholders as set forth on Schedule 9.2, will indemnify and hold the Buyer Indemnified Parties harmless against any Damages asserted against, resulting to, imposed upon or incurred by any such Buyer Indemnified Party, directly or indirectly, by reason of, resulting from or attributable to (i) any breach of the representations and warranties of Seller contained in Section 3.11, (ii) any Taxes payable with respect to Seller or any of its Subsidiaries for any Pre-Closing Period, (iii) any Taxes of any member of an affiliated, consolidated, combined or unitary group of which Seller or any of its Subsidiaries (or any predecessor of any of the foregoing) is or was a member prior to the Closing Date, including pursuant to Treasury Regulation Section 1.1502-6 or any analogous or similar state, local or foreign Law or regulation, which Taxes relate to an event or transaction occurring before the Closing, and (iv) any Taxes of any Person (other than Seller or any of its Subsidiaries) imposed on Seller or any of its Subsidiaries as a transferee or successor by contract or pursuant to any Law, rule, or regulation (other than customary contracts or agreements entered into in the ordinary course of business and any lending agreements the principal purpose of each of which is not with respect to Taxes), which Taxes relate to an event or transaction occurring before the Closing; provided, however, that in the case of clauses (i), (ii), (iii) or (iv) above, the Seller Securityholders shall be liable only to the extent that such Taxes exceed the amount, if any, taken into account in determining the Net Cash Balance. Any amounts for which Buyer is entitled to reimbursement pursuant to this Section 6.13(a) shall first be deducted from the Tax Escrow Amount and shall then be deducted from the General Escrow Amount and otherwise be subject to the provisions of Article IX. For the avoidance of doubt, none of the disclosures set forth in Section 3.11 of the Seller Disclosure Schedule shall modify or limit the obligations of the Seller Securityholders under this Section 6.13 except with regard to clause (i) above.

(b) In order to apportion appropriately any Taxes relating to the portion of a taxable period beginning on or before the Closing Date but ending after the Closing Date (a “Straddle Period”), the portion of any Taxes that are allocable to the Pre-Closing Period shall be: (A) in the case of Taxes that are imposed on a periodic basis (and not based on invoices, receipts, sales or payments), deemed to be the amount of such Taxes for the entire period multiplied by a fraction, the numerator of which is the number of calendar days in the Straddle Period ending on (and including) the Closing Date and the denominator of which is the number of calendar days in the entire relevant Straddle Period, and (B) in the case of Taxes not described in (A) (such as

taxes that are either (x) income Taxes, or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible)), deemed equal to the amount that would be payable if the Taxable year or period ended and the books closed at the close of the Closing Date.

(i) All Tax Returns of each of Seller and each of its Subsidiaries required to be filed between the date hereof and the Closing Date (i) will be filed (or will be caused to be filed) by Seller when due (after taking into account timely filed extensions) in accordance with all applicable Laws, (ii) will be prepared (or will be caused to be prepared) on a basis consistent with the most recent Tax Returns of each of Seller and each of its Subsidiaries unless there is no reasonable basis for such position and (iii) as of the time of filing, will be complete and accurate in all material respects. Buyer shall be permitted to review and comment on each such income Tax Return prior to the filing for at least seven (7) calendar days prior to the due date thereof. Seller shall consider in good faith any reasonable comments of Buyer on such Tax Returns. Seller shall pay, or cause to be paid, all Taxes with respect to such Tax Returns.

(ii) All Tax Returns of each of Seller and each of its Subsidiaries required to be filed after the Closing Date for any taxable period or portion thereof ending on or prior to the Closing Date (A) will be filed (or will be caused to be filed) by Buyer when due (after taking into account timely filed extensions) in accordance with all applicable Laws and (B) will be prepared (or will be caused to be prepared) on a basis consistent with the most recent Tax Returns of each of Seller and its Subsidiaries so long as there is a reasonable basis for the positions taken on such Tax Returns. With respect to any such income Tax Returns that could result in an indemnification obligation by the Seller Securityholders, at least fifteen (15) days prior to the due date therefor, Buyer shall provide such Tax Return to the Securityholders’ Representative for the Securityholders’ Representative’s review and Buyer shall consider in good faith any reasonable comments of the Securityholders’ Representative with respect to such Tax Returns.

(iii) Each of Buyer, Seller, each of its Subsidiaries and the Securityholders’ Representative shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to Section 6.13(a), and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Each of Buyer, Seller and each of its Subsidiaries agrees (A) to retain all books and records with respect to Tax matters pertinent to Seller and each of its Subsidiaries relating to any taxable period beginning before the Closing Date for a period of seven (7) years

following the date hereof (and, to the extent notified by Buyer or the Securityholders’ Representative, subject to any extensions thereof), and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, each of Buyer, Seller and each of its Subsidiaries, as the case may be, shall allow the other party to take possession of such books and records.

(iv) Each of Buyer, Seller, each of its Subsidiaries and the Securityholders’ Representative agrees upon request, to use its reasonable best efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby) upon Seller or any of its Subsidiaries.

(v) Each of Buyer, Seller and each of its Subsidiaries agrees, upon request, to provide the other party with all information that either party may be required to report pursuant to Sections 6043 or 6043A of the Code or Treasury Regulations promulgated thereunder.

(d) All Tax sharing agreements or similar agreements with respect to or involving Seller or any of its Subsidiaries shall be terminated as of the Closing Date and, after the Closing Date, neither Seller nor any of its Subsidiaries shall be bound thereby or have any liability thereunder.

(e) All sales and transfer taxes, recording charges and similar taxes, fees or charges imposed as a result of the transactions contemplated by this Agreement (collectively, the “Transfer Taxes”), together with any interest, penalties or additions to such Transfer Taxes, shall be paid one-half by Seller Securityholders and one-half by Buyer (on behalf of the Seller Securityholders). The Securityholders’ Representative and Buyer shall cooperate in timely making all filings, returns, reports and forms as necessary or appropriate to comply with the provisions of all applicable Laws in connection with the payment of such Transfer Taxes, and shall cooperate in good faith to minimize, to the fullest extent possible under such Laws, the amount of any such Transfer Taxes payable in connection therewith.

(f) Except to the extent taken into account in the determination of the Net Cash Balance, Buyer shall offset any refunds of Taxes of Seller or any of its Subsidiaries with respect to the current taxable period or portions thereof ending on or prior to the Closing Date (which for the avoidance of doubt, shall exclude carrybacks of any loss or deduction generated in a period after the Closing Date to any taxable period ending prior to the Closing Date) against the amount of any Damages to be paid to any Buyer Indemnified Party pursuant to this Section 6.13.

6.14 Section 280G of the Code. Prior to the Closing, Seller shall have used commercially reasonable efforts to seek the approval of the Seller Stockholders that complies with the requirements of Section 280G(b)(5) of the Code and Treasury Regulations § 1.280G-1

thereunder, with respect to payments and benefits that may be made or provided to any Person who, with respect to Seller, is a “disqualified individual” (as such term is defined for purposes of Section 280G of the Code) if such payments could reasonably be expected to result in the imposition of any excise tax imposed under Section 4999 of the Code (such vote, the “Requisite Section 280G Approval”). The taking of any such vote to obtain such Requisite Section 280G Approval, including all materials and information that are provided to the Seller Stockholders in connection with such vote, shall comply with applicable Laws and organizational documents of Seller. Copies of such materials will be provided to Buyer in advance of distribution to the Seller Stockholders, and Buyer will be provided with a reasonable opportunity to comment thereon.

6.15 Termination of Arrangements and Agreements.

Seller shall terminate all Seller Contracts listed on Schedule 6.15 on or prior to the Closing, including sending all required notices, such that each such Seller Contract shall be of no further force or effect immediately following the Closing, in each case without any remaining liability of any kind on the part of Seller, any of its Subsidiaries or Buyer as a result of or in connection with such termination or such Seller Contract.

Buyer shall not have any liability to Seller, any Seller Securityholder or any other Person for any liabilities resulting from Seller seeking to obtain such terminations.

Any liabilities of any kind on the part of Seller or any of its Subsidiaries that arise in connection with the performance by Seller of this Section 6.15 shall be included as Seller Transaction Expenses (whether matured or unmatured and whether or not yet due and payable), except to the extent released or fully satisfied on or before Closing without any further liability on the part of Seller, any of its Subsidiaries or Buyer.

6.16 FIRPTA Compliance. On the Closing Date, Seller shall deliver to Buyer a properly executed statement (a “FIRPTA Compliance Certificate”) in a form reasonably acceptable to Buyer for purposes of satisfying Buyer’s obligations under Treasury Regulation Section 1.1445-2(c)(3).

Unless, at least ten (10) Business Days prior to the Closing Date, Buyer provides written notice to Seller to the contrary, effective as of no later than the day immediately preceding the Closing Date, each of Seller and any ERISA Affiliate shall terminate any and all Seller Employee Programs intended to include a Code Section 401(k) arrangement (each, a “401(k) Plan”) and shall cause any professional employer organization or co-employer organization to terminate the participation of each Seller Employee

in any 401(k) Plan maintained by such organization. Unless Buyer provides written notice to Seller as contemplated in the foregoing sentence, no later than two (2) Business Days prior to the Closing Date, Seller shall provide Buyer with evidence that each 401(k) Plan has been terminated and the participation of each Seller Employee in each 401(k) Plan has been terminated, as applicable, (effective as of no later than the day immediately preceding the Closing Date) pursuant to resolutions of the Board of Directors of Seller, such ERISA Affiliate or organization, as the case may be. The form and substance of such resolutions shall be subject to review and approval of Buyer (which approval shall not be unreasonably withheld, conditioned or delayed). In the event that termination of a 401(k) Plan would reasonably be anticipated to trigger liquidation charges, surrender charges or other fees then such charges or fees shall be included in Seller Transaction Expenses and shall be the responsibility of Seller, and Seller shall take such actions as are necessary to reasonably estimate the amount of such charges or fees and provide such estimate in writing to Buyer no later than two (2) Business Days prior to the Closing Date.

6.20 Proprietary Information Agreements. From the date hereof until the Closing Date, Seller shall use its commercially reasonable efforts to cause each of the administrative employees of Seller and its Subsidiaries to enter into and execute a proprietary information agreement with Seller in a form reasonably satisfactory to Buyer.

(a) From and after the Closing, all representations, warranties, covenants, and agreements of the Seller, Buyer and Merger Sub made in this Agreement, in the Seller Disclosure Schedule delivered to Buyer, in the Buyer Disclosure Schedule delivered to Seller and all certificates executed and delivered in connection with Sections 7.2(a), 7.2(b), 7.3(a) and 7.3(b) hereof (i) shall be deemed to be material and to have been relied upon by the party or parties to whom they are made, and shall survive the Closing regardless of any investigation on the part of such party or its representatives, with each party reserving all of its rights hereunder in connection with any breach or alleged breach pursuant to the terms of this Agreement and (ii) shall bind the parties’ successors and assigns (including, without limitation, any successor to Buyer or Seller by way of acquisition, merger or otherwise), whether so expressed or not, and, except as otherwise provided in this Agreement, all such representations, warranties, covenants and agreements shall inure to the benefit of the parties (subject to Section 11.9 below) and their respective successors and assigns, whether so expressed or not.

(b) Notwithstanding Section 9.1(a), from and after the Closing, the representations and warranties of the Seller, Buyer and Merger Sub made in this Agreement, in the Seller Disclosure Schedule delivered to Buyer, in the Buyer Disclosure Schedule delivered to Seller and the certificates executed and delivered in connection with Sections 7.2(a) and 7.3(a) hereof (and related indemnification obligations) shall expire and terminate on the date which is eighteen (18) months from the Closing Date, and be of no further force and effect thereafter, except that (i) the representations and warranties of Seller set forth in Sections 3.2 and 3.3 (and related indemnification obligations) shall expire and terminate on the date which is the third (3rd) anniversary of the Closing Date, and be of no further force and effect thereafter, (ii) the representations and warranties of Seller set forth in Section 3.18 (and related indemnification obligations) shall expire and terminate on the date which is the second (2nd) anniversary of the Closing Date, and be of no further force and effect thereafter, and (iii) the representations and warranties of the Seller set forth in Section 3.11 (and related indemnification obligations) shall expire and terminate on the date which is sixty (60) days following the expiration of the applicable statute of limitations, and be of no further force and effect thereafter (collectively, the

representations referred to in clauses (i) through (iii) above, the “Seller Fundamental Representations”). Notwithstanding Section 9.1(a), the indemnification covenants of the Seller Securityholders set forth in Section 6.13 shall expire and terminate on the date which is sixty (60) days following the expiration of the applicable statute of limitations. Further notwithstanding Section 9.1(a), from and after the Closing, all covenants and agreements of the parties made in this Agreement other than those in Section 6.13 (which shall expire and be of no further force or effect as set forth in the prior sentence), in the Seller Disclosure Schedule delivered to Buyer, in the Buyer Disclosure Schedule delivered to Seller and the certificates executed and delivered in connection with Sections 7.2(b) and 7.3(b) hereof shall expire and be of no further force or effect as of the Closing, except to the extent such covenants or agreements provide that they are to be performed after the Closing in which case they shall expire in accordance with their terms or if no term is expressly stated herein, until their respective statutes of limitations. Any claims for fraud or willful breach shall expire and terminate on the expiration date of their applicable statute of limitations.

(c) No party hereto shall have any indemnification obligation pursuant to this Article IX or otherwise in respect of any representation, warranty, covenant or agreement unless it shall have received from the party seeking indemnification written notice of the existence of the claim for which indemnification is being sought on or before the expiration (if any) of the period for which the representation, warranty, covenant or agreement underlying such claim survives. Any written claim for indemnification pursuant to this Article IX in respect of any representation, warranty, covenant or agreement that is made prior to the applicable expiration date (if any) for such representation, warranty, covenant or agreement and delivered to the party against whom such indemnification is sought in accordance with the provisions of this Article IX, shall survive thereafter and, as to any such claim, such subsequent expiration will not affect the rights to indemnification of the party making such claim, it being agreed that if such claim for indemnification is timely made, the relevant representations, warranties, covenants and agreements shall survive with respect to the claims for indemnification set forth in such notice until such matter is resolved. Such notice shall set forth with reasonable specificity (i) the basis under this Agreement and the facts that otherwise form the basis of such claim and (ii) the estimate of the amount of such claim (which estimate shall not be conclusive of the final amount of such claim).

(d) Notwithstanding anything in this Article IX or any other provision of this Agreement to the contrary, subject to the last sentence of Section 9.1(b) on survivability and the limitations in Section 9.4, in the event of any acts of fraud committed by the Seller, Buyer or Merger Sub or willful breach committed by the Seller, Buyer or Merger Sub, the parties shall have all remedies available at Law or in equity (including for tort) with respect to such fraud or willful breach.

9.2 Indemnification by the Seller Securityholders. Subject to the terms and conditions of this Article IX, from and after the Closing, the Seller Securityholders, severally and not jointly, and in accordance with their pro rata share of the Merger Consideration in relation to all other Seller Securityholders as set forth on Schedule 9.2, shall indemnify, defend and hold harmless Buyer, the Surviving Corporation, their respective affiliates and the respective officers, directors, employees, agents and representatives of Buyer, the Surviving Corporation and their respective affiliates (the “Buyer Indemnified Parties”) from and against any and all actual claims,

actions, causes of action, demands, assessments, losses, damages, liabilities, judgments, settlements, penalties, costs, and expenses (including reasonable attorneys’ fees and expenses) of any nature whatsoever (collectively, “Damages”) asserted against, resulting to, imposed upon, or incurred by any such Buyer Indemnified Party, directly or indirectly, by reason of or resulting from (i) any breach of (A) any of the representations and warranties contained in Article III of this Agreement (including the Seller Disclosure Schedule but other than the representations and warranties contained in Section 3.11 which are covered in clause (ii) below) or the certificate delivered at the Closing pursuant to Section 7.2(a) hereto by or on behalf of Seller to Buyer in connection with the transactions contemplated hereby (other than a bring-down of the representations and warranties covered in Section 3.11, which are covered in clause (ii) below) or (B) any of the covenants and agreements of Seller (other than the covenant to indemnify for Taxes pursuant to Section 6.13, which is covered in clause (ii) below), and (ii) any and all Taxes for which the Seller Securityholders are responsible pursuant to Section 6.13. The Buyer Indemnified Parties shall seek recovery for indemnification claims under this Article IX and Section 6.13 and the Escrow Agreement (i) out of the Net Cash Escrow Account solely to satisfy amounts payable to Buyer pursuant to Section 2.4 and the Tax Escrow Account solely to satisfy amounts payable to Buyer pursuant to Section 6.13, each in the first instance until the Net Cash Escrow Account is exhausted for satisfying amounts payable pursuant to Section 2.4 or is otherwise fully distributed or fully reserved against, the Tax Escrow Account is exhausted for satisfying amounts payable pursuant to Section 6.13 or is otherwise fully distributed or fully reserved against and then, in each case, second against the General Escrow Account, and (ii) out of the General Escrow Account in the first instance for all other indemnification claims under this Article IX until the General Escrow Account is exhausted or otherwise fully distributed or fully reserved for pending claims in full, as applicable, and thereafter, the Buyer Indemnified Parties shall be entitled to seek recovery for such indemnification claims directly from the Seller Securityholders, subject to the limitations set forth in this Article IX and the Escrow Agreement. Notwithstanding any other provision of this Agreement, the Seller Securityholders shall not have any liability for any Taxes of Seller or any of its Subsidiaries for taxable periods or portions thereof beginning after the Closing Date.

9.3 Indemnification Proceedings for Third Party Claims. In the event that any claim or demand for which a party (an “Indemnifying Party”) would be liable to another party under Section 9.2 (an “Indemnified Party”) is asserted against or sought to be collected from an Indemnified Party by a third party, the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such claim or demand, but the failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article IX, except to the extent the Indemnifying Party demonstrates that the defense of such claim or demand is materially prejudiced thereby. The Indemnifying Party shall have sixty (60) days from receipt of the above notice from the Indemnified Party (in this Section 9.3, the “Notice Period”) to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party’s sole cost and expense, and subject to the Indemnifying Party’s written agreement to accept full responsibility for indemnification and payment of any Damages with respect to such claim or demand (to extent there are any Damages related to such claim or demand), to assume the defense of such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and not prejudicial to the Indemnifying Party. If the Indemnifying Party

elects to assume the defense of any such claim or demand, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof. If the Indemnifying Party elects not to assume the defense of such claim or demand (or fails to give notice to the Indemnified Party during the Notice Period), the Indemnified Party shall be entitled to assume the defense of such claim or demand with counsel of its own choice, at the expense of the Indemnifying Party. If the claim or demand is asserted against both the Indemnifying Party and the Indemnified Party and based on the advice of counsel reasonably satisfactory to the Indemnifying Party it is determined that there is a conflict of interest which renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be responsible for paying separate counsel for the Indemnified Party; provided, however, that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys to represent all of the Indemnified Parties, regardless of the number of Indemnified Parties. If the Indemnifying Party elects to assume the defense of such claim or demand, (i) no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnified Party’s written consent (which shall not be unreasonably withheld, conditioned or delayed) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party, the settlement does not include any admission of liability and the Indemnified Party is fully released from all liabilities relating to such claim or demand and (ii) the Indemnified Party shall have no liability with respect to any compromise or settlement thereof effected without its written consent (which shall not be unreasonably withheld, conditioned or delayed). In addition, the Indemnifying Party shall keep the Indemnified Party apprised of the status of the claim, liability or expense and any resulting suit, proceeding or enforcement action, shall furnish the Indemnified Party with all documents and information that the Indemnified Party shall reasonably request and shall consult with the Indemnified Party prior to acting on major matters, including settlement discussions. In the event that the Indemnifying Party does not assume the defense of such claim or demand, the Indemnified Party shall keep the Indemnifying Party apprised of the status of the claim, liability or expense and any resulting suit, proceeding or enforcement action, shall furnish the Indemnifying Party with all documents and information that the Indemnifying Party shall reasonably request and shall consult with the Indemnifying Party prior to acting on major matters, including settlement discussions. The Indemnifying Party may not enter into any compromise or settlement of such claim or demand in which the Indemnifying Party receives a release from all liabilities relating to such claim or demand in connection with a compromise or settlement, unless such release also applies to the Indemnifying Party. With respect to any claim subject to indemnification under this Article IX, the parties shall cooperate in such a manner and use their commercially reasonable efforts to preserve in full the confidentiality of all confidential information and the attorney-client and work-product privileges. In connection therewith, each party agrees that: (i) it will use commercially reasonable efforts, in respect of any claim in which it has assumed or has participated in the defense, to avoid production of confidential information (consistent with applicable law and rules of procedure) and (ii) it will use commercially reasonable efforts to make all communications between any parties hereto and counsel responsible for or participating in the defense of any third-party claim will so as to preserve any applicable attorney-client or work-product privilege.

9.4 Certain Limitations.

(a) Notwithstanding anything to the contrary in this Agreement, the Seller Securityholders shall not have any liability to the Buyer Indemnified Parties for any claims for indemnification made by the Buyer Indemnified Parties pursuant to this Agreement except as satisfied out of and subject to the amount in the General Escrow Account (such aggregate amount, the “Cap”); provided, however, that the Cap shall not apply to any Damages based upon, arising out of, or by reason of any breach of the Seller Fundamental Representations, the indemnification covenants in Section 6.13 or fraud or willful breach.

(b) Notwithstanding anything to the contrary in this Agreement, no Seller Securityholder shall have any liability to the Buyer Indemnified Parties for any claims for indemnification made by the Buyer Indemnified Parties pursuant to this Agreement based upon, arising out of, or by reason of any one or more breaches of any one or more of the Seller Fundamental Representations or arising out of the indemnification covenants of Section 6.13 in excess of such Seller Securityholder’s pro rata share of such claim up to such Seller Securityholder’s pro rata share of $150,000,000 in the aggregate for all such claims (the “Fundamental Representation Cap”).

(c) Notwithstanding anything to the contrary in this Agreement, no Seller Securityholder shall have any liability to the Buyer Indemnified Parties for any claims for indemnification made by the Buyer Indemnified Parties pursuant to this Agreement based upon, arising out of, or by reason of any one or more claims for fraud committed by the Seller or willful breach committed by the Seller in excess of such Seller Securityholder’s pro rata share of such claim up to the Merger Consideration actually received by such Seller Securityholder in the aggregate for all such claims. Notwithstanding anything to the contrary in this Agreement, the Seller Securityholders shall not have any liability for indemnification claims, in the aggregate, including all recoveries pursuant to any and all claims under this Agreement, in excess of the Merger Consideration actually received by such Seller Securityholder. For the avoidance of doubt and notwithstanding anything in this Agreement, to the extent that an indemnification payment made pursuant to this Agreement is subject to a cap specified in this Section 9.4 or the Net Cash Escrow Amount or the Tax Escrow Amount, such payment shall reduce all caps specified in this Section 9.4, if any, by the aggregate amount of such payments; provided that any indemnification payment made pursuant to this Article IX that is made out of the Tax Escrow Account shall not reduce the amount of the Cap.

(d) Except in the case of fraud committed by the Seller or willful breach committed by the Seller, the Seller Securityholders shall not have any liability under this Article IX unless and until the aggregate amount of all Damages incurred by the Buyer Indemnified Parties and indemnifiable hereunder exceeds $500,000 (the “Basket”) and, once such Damages reach the Basket, the Seller Securityholders shall be required to pay only those Damages that are in excess of the Basket, subject to the limitations and provisions set forth in this Article IX.

(e) The amount of any Damages payable by the Indemnifying Party to the Indemnified Party shall be net of (i) any amounts actually recovered by the Indemnified Party under applicable insurance policies (less any directly resulting increases in premium), and (ii) any net Tax benefit available to such Indemnified Party or its Affiliates arising in connection with the accrual, incurrence or payment of any such Damages, to the extent such net Tax Benefit is realized, determined on a with and without basis, in the taxable year in which such payment

for Damages was made. For the purposes of calculating the net Tax benefit under the foregoing sentence, Buyer shall have reasonable discretion to determine the amount of such Tax benefit and shall have no obligation to share or disclose any of its Tax Returns in connection therewith with the Securityholders’ Representative, Seller or any of its Subsidiaries; provided such calculations are made in good faith. Each Indemnified Party shall use its commercially reasonable efforts to recover under insurance policies for any Damages prior to seeking indemnification under this Agreement.

(f) The Buyer Indemnified Parties shall not be entitled to recover under Article IX for lost profits, special, consequential, indirect or punitive damages; provided, however, that the foregoing limitation shall not preclude any indemnitee from claiming Damages based on diminution in value, including Damages calculated by application of a multiple, but a multiple will only be applied to the extent that (and only to the extent that) the basis for such Damages is of a recurring nature.

(g) Notwithstanding anything contained in this Agreement to the contrary, no Buyer Indemnified Party shall have any right to indemnification under this Article IX with respect to any Damages to the extent such Damages (i) arise solely out of changes after the Closing Date in applicable Law or interpretations or applications thereof; or (ii) are duplicative of Damages that have previously been recovered (including, without limitation, amounts taken into account in the calculation of Merger Consideration, Initial Merger Consideration or Net Cash Balance).

(h) For purposes of this Agreement and the transactions contemplated hereby, Buyer, Merger Sub and Seller acknowledge and agree (i) that they are not entitled to rely on any representations or warranties or other statements of fact or opinion, other than the representations and warranties expressly set forth in this Agreement, the Seller Disclosure Schedule and the Buyer Disclosure Schedule, and (ii) that in connection with the transactions set forth herein, Buyer has received certain estimates, projections, forecasts and similar forward-looking statements relating to the future operating and financial performance of Seller and its Subsidiaries and no representation or warranty is being made by or on behalf of Seller with respect to such matters. Buyer, Merger Sub and Seller also acknowledge and agree that anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of any Buyer Indemnified Parties, after the consummation of the transactions contemplated by this Agreement, to rescind this Agreement or any of the transactions contemplated hereby.

(i) Notwithstanding anything to the contrary in this Agreement or the Escrow Agreement, Buyer and each of the other Buyer Indemnified Parties agree to keep the Securityholders’ Representative regularly informed regarding, and cooperate with the Securityholders’ Representative with respect to, any Tax for which the Seller Securityholders may have indemnification obligations pursuant to this Agreement and to use its commercially reasonable efforts to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby) upon Seller or any of its Subsidiaries or upon the Seller Securityholders. These efforts include negotiating in good faith with Governmental Authorities or any other Person to reduce any such Tax obligation. In the event that any Buyer Indemnified Party intends to pay any Tax for which the Seller

Securityholders may have indemnification obligations pursuant to this Agreement for a Taxable period ending on or prior to the Closing Date, or portions thereof, for which a Governmental Authority or any other Person has not sought payment or asserted that Buyer, the Surviving Corporation or any of their respective Subsidiaries owes any Taxes (or has not paid Taxes owed), Buyer shall provide written notice to the Securityholders’ Representative three (3) months prior to paying any such amount. During such three (3)-month period, to the extent requested by the Securityholders’ Representative, Buyer and its Representatives shall meet in person with the Securityholders’ Representative and its Representatives so that the Securityholders’ Representative may provide Buyer with its view on payment of such amount and/or the amount of such payment, and their reasonable basis for believing such amounts should not be paid or that a lesser amount should be paid. Notwithstanding the foregoing, upon the expiration of such three (3)-month period, Buyer shall have the sole and exclusive right to determine whether or not to pay any such amounts. In the event that Buyer, the Surviving Corporation or their respective Subsidiaries enter into any compromise or settlement with regard to such Taxes with any Governmental Authority or any other Person in which Buyer, the Surviving Corporation or any of their respective Subsidiaries receives a release from liabilities relating to such Taxes in connection with such compromise or settlement, Buyer shall use its commercially reasonable efforts to have such Governmental Authority or other Person enter into a release of the Seller Securityholders and the Securityholders’ Representative on the same terms as the release applicable to the Buyer, the Surviving Corporation or their respective Subsidiaries, as applicable. Nothing in this Section 9.4(i) shall be construed to limit Buyer’s right and ability to make an indemnification claim pursuant to this Agreement or the Escrow Agreement, provided a Buyer Indemnified Party complies with the terms of this Agreement and the Escrow Agreement, or to limit the Securityholders’ Representative’s right and ability to contest such indemnification claim. For the avoidance of doubt, any claim for Taxes under this Agreement is subject to the provisions of Section 9.3 of this Agreement.

9.5 Exclusivity. After the Closing Date, this Article IX, Article II and the indemnification covenants in Section 6.13 and Sections 3, 5, 6 and 12 of the Escrow Agreement shall provide the exclusive remedy for breaches of representations, warranties, covenants and agreements set forth in this Agreement, in the Seller Disclosure Schedule delivered to Buyer, in the Buyer Disclosure Schedule delivered to Seller and in the certificates executed and delivered in connection with Sections 7.2(a), 7.2(b), 7.3(a) and 7.3(b) hereto, except with respect to matters for which the remedy of specific performance, injunctive relief or other non-monetary equitable remedies are available. All obligations of the Seller Securityholders pursuant to this Agreement and the Escrow Agreement shall be satisfied (a) first, severally but not jointly from the Net Cash Escrow Account, Tax Escrow Account and the General Escrow Account, as applicable, and in the case of the Net Cash Escrow Account or the Tax Escrow Account, second against the General Escrow Account after the Net Cash Escrow Account or the Tax Escrow Account, as applicable, has been exhausted, fully distributed or fully reserved for outstanding claims, and, in each case, in accordance with each Seller Securityholder’s pro rata share of the Merger Consideration in relation to all other Seller Securityholders as set forth on Schedule 9.2, and subject to the terms, conditions and limitations set forth in this Agreement and the Escrow Agreement and (b) second or third, as the case may be, by the Seller Securityholders, severally but not jointly and in accordance with each Seller Securityholder’s pro rata share of the Merger Consideration in relation to all other Seller Securityholders as set forth on Schedule 9.2, and subject to the terms, conditions and limitations set forth in this Agreement and the Escrow Agreement.

9.6 Exercise of Remedies by Buyer Indemnified Parties Other Than Buyer. No Buyer Indemnified Party (other than Buyer or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement unless Buyer (or any successor thereto or assign thereof) shall have consented to the assertion of such indemnification claim or the exercise of such other remedy.

9.7 Merger Consideration Adjustment. The parties agree to treat any indemnity payments made under this Agreement as adjustments to the Merger Consideration, to the extent permitted by applicable Law.

ARTICLE X - SECURITYHOLDERS’ REPRESENTATIVE

10.1 Securityholders’ Representative.

(a) Each Seller Securityholder by approving this Agreement and the transactions contemplated hereby, executing a Letter of Transmittal and/or participating in the Merger and accepting the benefits thereof, hereby irrevocably and unconditionally appoints Papachey, Inc. as its true and lawful attorney-in-fact, to act as its representative (“Securityholders’ Representative”) under this Agreement and, as such, to act, as such holder’s agent (with full power of substitution), to take such action on such holder’s behalf with respect to all matters relating to this Agreement, the Merger and the transactions contemplated hereby, including (i) to execute and deliver all certificates and documents that the Securityholders’ Representative deems necessary or appropriate in connection with the consummation of the Merger; (iii) to receive and provide a receipt for all payments made by Buyer and/or Seller to any of the Seller Securityholders under this Agreement; (iv) to pay for or reimburse itself for the costs and expenses of the Securityholders’ Representative under this Agreement and the Escrow Agreement out of the Securityholders’ Representative Expense Fund; (v) to terminate, amend or waive any provision of this Agreement or the Escrow Agreement, provided that any such termination, amendment or waiver, if material to the rights and obligations of the Seller Securityholders in the reasonable judgment of the Securityholders’ Representative, shall be taken in the same manner with respect to all holders unless otherwise agreed by each holder who is subject to any disparate treatment of a potentially adverse nature; (vi) to defend and settle all disputes and claims that arise under this Agreement or the Escrow Agreement or any other, certificate or instrument delivered in connection with this Agreement or the Escrow Agreement; and (vii) to do or refrain from doing any further act or deed on behalf of such holders that the Securityholders’ Representative deems necessary or appropriate in such Person’s sole discretion relating to the subject matter of this Agreement and the Escrow Agreement as fully and completely as any Seller Securityholder could do if personally present and acting. All decisions and actions by the Securityholders’ Representative, including any agreement between the Securityholders’ Representative and the Buyer Indemnified Parties relating to indemnification obligations of the Seller Securityholders under Article IX, including the defense or settlement of any claims and the making of payments with respect hereto, shall be binding upon all of the Seller Securityholders, and no holder shall have the right to object, dissent, protest or otherwise contest the same. The Securityholders’ Representative shall incur no liability to the Seller

Securityholders with respect to any action taken or suffered by such holders in reliance upon any notice, direction, instruction, consent, statement or other documents believed by the Securityholders’ Representative to be genuinely and duly authorized, nor for any other action or inaction taken in its capacity as the Securityholders’ Representative, including with respect to the indemnification obligations of the Seller Securityholders under Article IX, including the defense or settlement of any claims and the making of payments with respect thereto. The Securityholders’ Representative may, in all questions arising under this Agreement, the Escrow Agreement and the transactions contemplated thereby, rely on the advice of counsel, and for anything done, omitted or suffered in good faith by the Securityholders’ Representative shall not be liable to the Seller Securityholders.

(b) Buyer and the Escrow Agent shall be entitled to conclusively rely on the instructions, decisions and acts of Securityholders’ Representative, the Escrow Agent and Buyer are hereby released and relieved from any liability to any Person for any acts done by them in accordance with any instructions, decisions or acts of the Securityholders’ Representative. Buyer and the Escrow Agent are each hereby expressly authorized to rely on the genuineness of the signature of the Securityholders’ Representative or any instrument, certificate or document. Upon receipt of any writing that has been signed by the Securityholders’ Representative, Buyer and the Escrow Agent may each act upon the same without any further duty of inquiry as to the genuineness of the writing.

(c) The Securityholders’ Representative shall be entitled to conclusively rely, and shall be fully protected from action by the Seller Securityholders in relying, upon any statements furnished to it by any holder, or Buyer, or any other evidence deemed by the Securityholders’ Representative to be reliable, and the Securityholders’ Representative shall be entitled to act on the advice of counsel selected by it.

(d) By approving this Agreement, executing the Letter of Transmittal and/or participating in the Merger and accepting the benefits thereof, the Seller Securityholders immediately prior to the Effective Time agree on a several and not joint basis to (i) indemnify the Securityholders’ Representative (in its capacity as such) against and to hold the Securityholders’ Representative (in its capacity as such) harmless from, any and all Damages which may at any time be imposed upon, incurred by or asserted against the Securityholders’ Representative in such capacity in any way relating to or arising out of its action or failure to take action pursuant to this Agreement or the Escrow Agreement or in connection herewith in such capacity, and (ii) to pay the Securityholders’ Representative for all costs and expenses incurred on behalf of the Seller Securityholders, promptly upon demand by the Securityholders’ Representative and on an as-incurred basis, on a pro rata basis. The agreements in this Article X shall survive termination of this Agreement.

(e) The Securityholders’ Representative shall be entitled to reimbursement from the Seller Securityholders through the Securityholders’ Representative Expense Fund and, once exhausted, otherwise directly from such Seller Securityholders on a pro rata basis for out of pocket fees and expenses (including legal, accounting and other advisors’ fees and expenses, if applicable) incurred by the Securityholders’ Representative in performing its obligations under this Agreement and the Escrow Agreement.

11.3 Interpretation. When a reference is made in this Agreement to Sections, Exhibits, or Schedules, such reference shall be to a Section of, or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes,” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” No provision of this Agreement shall be construed to require Seller, Buyer or Merger Sub or any of their respective Subsidiaries or Affiliates to take any action that would violate applicable law, rule, or regulation.

11.4 Rules of Construction. The parties to this Agreement agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore,

waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

11.5 Counterparts. This Agreement may be executed in counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

11.6 Entire Agreement. This Agreement, together with the Exhibits and Schedules hereto, the Confidentiality Agreement and any documents delivered by the parties in connection herewith constitutes the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties hereto, or any of them, with respect to the subject matter hereof.

11.7 Governing Law; Jurisdiction and Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its rules of conflict of laws. Each of Buyer, Merger Sub and Seller hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the courts of the State of Delaware and of the United States of America located in the State of Delaware (the “Delaware Courts”) for any litigation arising out of or relating to this Agreement and the transactions contemplated hereby (and agrees not to commence any litigation relating thereto except in such courts), waives any objection to the laying of venue of any such litigation in the Delaware Courts, and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum. Each of the parties hereto agrees, (a) to the extent such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party’s agent for acceptance of legal process, and (b) that service of process may also be made on such party by prepaid certified mail with a proof of mailing receipt validated by United States Postal Service constituting evidence of valid service. Service made pursuant to (a) or (b) above shall have the same legal force and effect as if served upon such party personally with the State of Delaware.

11.8 Severability.
