the Effective Time, (y) the number of shares of Series B Preferred Stock outstanding immediately prior to the Effective Time and (z) the number of Vested Company Options that will be cashed out pursuant to Section 1.6(a) outstanding immediately prior to the Effective Time;

For the avoidance of doubt, Parent shall not be required to pay any amounts pursuant to Section 1.5 and Section 1.6(a) hereunder to the holders of Company Capital Stock and Vested Company Options in excess of the Total Merger Consideration. To the extent that, during the Pre-Closing Period, there is a change in the conversion ratio of the Series B Preferred Stock, or the number of shares of Series A Preferred Stock outstanding, or any other event which would cause the payments contemplated by Section 1.5 and Section 1.6(a) to be in excess of the Total Merger Consideration, then the amounts contemplated to be so paid as set forth therein shall be proportionately or equitably adjusted to give effect to any such change or event such that the aggregate payments required to be made pursuant to such Section 1.5 and Section 1.6(a) shall not exceed the amount of the Total Merger Consideration.

1.6 Company Options.

(a) Parent shall not assume any Vested Company Options in connection with the transactions contemplated hereby. Rather, at the Effective Time, by virtue of the Merger, without any action on the part of any holder of any Company Options and pursuant to the terms of the Company Stock Option Plans, each Vested Company Option shall be cancelled, and the holder of each Vested Company Option shall be entitled to receive, in full satisfaction of the rights of such holder with respect thereto: (i) an amount in cash equal to the product of (A) the excess of (1) the Per Share Common Closing Consideration, less (2) the exercise price per share of Company Common Stock subject to such Vested Company Option,

4

multiplied by (B) the number of shares of Company Common Stock subject to such Vested Company Option (such amount, the “ Option Payment ,” and the sum total of all payments to holders of Vested Company Options pursuant to this Section 1.6(a) shall be referred to collectively as the “ Aggregate Option Payment ”); and (ii) upon release pursuant to the terms of the Escrow Agreement, an amount in cash equal to the product of (A) the Per Share Common Escrow Consideration, multiplied by (B) the number of shares of Company Common Stock subject to such Vested Company Option; provided , however , that the distribution and amount of the Per Share Common Escrow Consideration is subject to reduction to satisfy indemnification obligations in accordance with the terms of the Escrow Agreement and Article 9 of this Agreement. An amount of cash equal to the Aggregate Option Payment shall be delivered by Parent promptly after the Effective Time to the Company. Within five Business Days following the Closing Date, the Surviving Corporation shall distribute to each holder of cancelled Vested Company Options an amount equal to his or her Option Payment.

(b) The terms of each outstanding unvested Company Option shall be adjusted as necessary to provide that, at the Effective Time, each unvested Company Option that is then outstanding under the Company Stock Option Plans shall be converted, replaced, substituted or assumed by Parent in accordance with the terms of the Company Stock Option Plans and the stock option agreements by which such Company Option is evidenced (the “ Substituted Options ”). Parent shall assume the Company Stock Option Plans at the Effective Time. Notwithstanding anything to the contrary contained in this Agreement, nothing in this Agreement shall result in Parent having “Assumed” the Company Options within the meaning of the Company’s 2007 Stock Incentive Plan. All rights with respect to Company Common Stock under each Substituted Option then outstanding shall be converted into and become rights with respect to Parent Common Stock, and Parent shall convert, replace, substitute or assume each such Substituted Option in accordance with the terms and conditions (as in effect as of the date of this Agreement) of the Company Stock Option Plans under which it was originally issued and the terms and conditions of the stock option agreement by which it is evidenced. From and after the Effective Time, (i) each Substituted Option may be exercised solely for shares of Parent Common Stock, (ii) the number of shares of Parent Common Stock subject to each Substituted Option shall be equal to the number of shares of Company Common Stock subject to such Substituted Option immediately prior to the Effective Time multiplied by the Option Exchange Ratio, rounding down to the nearest whole share, (iii) the per share exercise price under each such Substituted Option shall be adjusted by dividing the per share exercise price under such Substituted Option by the Option Exchange Ratio and rounding up to the nearest cent, and (iv) any restriction on the exercise of any such Substituted Option shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Substituted Option shall otherwise remain unchanged. The term “ Option Exchange Ratio ” shall be equal to the fraction (rounded to the third decimal point) obtained by dividing the Per Share Common Closing Consideration by the Parent Stock Price. “ Parent Stock Price ” shall mean the average of the closing sales prices for one share of Parent Common Stock on the NASDAQ Global Select Market on the five trading days ending three Business Days prior to the Closing Date.

(c) The Company shall take all requisite action to effectuate the foregoing provisions of this Section 1.6, including making any changes to the Company Stock Option Plans as Parent and the Company may reasonably agree are appropriate to give effect to the Merger.

1.7 Closing of the Company’s Transfer Books. At the Effective Time, holders of certificates representing shares of Company Capital Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as Company Shareholders, except the right to receive the Merger Consideration and the stock transfer books of the Company shall be closed with respect to all shares of such Company Capital Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Capital Stock (a “ Company Stock Certificate ”) is presented to the Surviving Corporation or Parent, such Company Stock Certificate shall be cancelled and shall be exchanged as provided in Section 1.8.

1.8 Exchange of Certificates.

The Company shall deliver a copy of the Merger Consideration Allocation Schedule to the Shareholders’ Representative.

(b) Prior to the Closing Date, Parent shall select a reputable bank or trust company reasonably acceptable to the Company to act as exchange agent in the Merger (the “ Exchange Agent ”). Promptly, but in no event later than one Business Day, after the Effective Time, Parent shall deposit, or cause to be deposited, with the Exchange Agent in trust for the benefit of the holders of Company Stock Certificates immediately available funds in an amount not less than the amount necessary to make the payments for the shares of the Company Capital Stock contemplated by Section 1.5 (such amount, the “ Exchange Fund ”).

(c) Within five Business Days after the Effective Time, Parent shall cause the Exchange Agent to mail to the record holders of Company Stock Certificates a letter of transmittal in customary form, and instructions for use in effecting the surrender of Company Stock Certificates in exchange for the Merger Consideration. Upon surrender of a Company

Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent, each holder of a Company Stock Certificate shall receive in exchange therefor, the Merger Consideration payable at Closing with respect to the shares formerly represented by such Company Stock Certificate as soon as practicable after the Effective Time. All Company Stock Certificates so surrendered shall be cancelled. Until surrendered as contemplated by this Section 1.8, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the Merger Consideration in accordance with this Agreement. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the payment of the Merger Consideration, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and indemnity against any claim that may be made against Parent or the Surviving Corporation with respect to such Company Stock Certificate. Parent shall deliver a copy of the letter of transmittal to the Shareholders’ Representative.

(d) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date 180 days after the date on which the Effective Time occurs shall be delivered to the Surviving Corporation upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.8 shall thereafter look only to the Surviving Corporation for satisfaction of their claims for the consideration relating thereto.

(e) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any portion of the Exchange Fund properly delivered to any public official as required by any applicable abandoned property law, escheat law or similar Legal Requirement.

1.9 Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Capital Stock held by a holder who, pursuant to Chapter 13 of the CGCL or any successor provision, has the right to dissent to the Merger and demand payment for such shares and has not failed to perfect, withdrawn or lost such rights (“ Dissenting Shares ”) in accordance with the CGCL, shall not be converted into the right to receive the Merger Consideration. If, after the Effective Time, such holder withdraws, fails to perfect or loses any such right to payment, such holder’s Dissenting Shares shall be treated as having been converted as of the Effective Time into the right to receive the Merger Consideration, without interest, such holder would have otherwise been entitled to receive in accordance with Section 1.5 of this Agreement. At the Effective Time, any holder of Dissenting Shares shall cease to have any rights with respect thereto, except the rights provided in Chapter 13 of the CGCL or any respective successor provision to such provision and as provided in the immediately preceding sentence. The Company shall give prompt notice to Parent of any demands received by the Company for appraisal of shares of Company Capital Stock and the opportunity to participate in all negotiations and proceedings with respect to any such demand. Except to the extent otherwise required by the CGCL, the Company shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand unless Parent shall have consented in writing to such payment or settlement offer.

1.10 Escrow Fund. Upon the Closing, Parent shall withhold the Escrow Amount and deliver it to Wells Fargo Bank, National Association, a national banking association (the “ Escrow Agent ”), to be held by the Escrow Agent as collateral (the “ Escrow Fund ”) and security for the rights of the Indemnitees under Article 9 hereof. The Escrow Fund shall be held pursuant to the provisions of an escrow agreement substantially in the form of Exhibit D (the “ Escrow Agreement ”). Subject to the next sentence of this Section 1.10, the Escrow Fund shall be held as an indemnification fund by the Escrow Agent until 11:59 p.m. Pacific Time on the date that is the first-year anniversary of the Closing Date (the “ Escrow Period ”). In the event any Indemnitee has made a claim under Article 9 prior to the end of the Escrow Period, then the Escrow Period shall continue (and the Escrow Agent will continue to hold only that portion of the Escrow Fund in escrow equal to the claimed amount) until such claim is fully and finally resolved. In the event that the principal terms of this Agreement and the Agreement of Merger are approved by the Company Shareholders, then all such Company Shareholders shall, without any further act of any Company Shareholder, be deemed to have consented to and approved (a) the use of the Escrow Fund as collateral to secure the rights of the Indemnitees under Article 9 in the manner set forth herein and in the Escrow Agreement and (b) the appointment of the Shareholders’ Representative as the representative under the Escrow Agreement of the Persons receiving Merger Consideration under this Agreement and as the attorney-in-fact and agent for and on behalf of each such Person (other than holders of Dissenting Shares).

1.11 Shareholders’ Representative Funds. Upon the Closing, Parent shall pay to the Shareholders’ Representative an amount equal to $300,000 to be held by the Shareholders’ Representative (the “ Shareholders’ Representative Funds ”) in a segregated, non-interest bearing account to be used for the expenses incurred by the Shareholders’ Representative while acting on behalf of the Company Shareholders under the authorization granted in Section 10.1. Promptly after the resolution of all claims against the Escrow Fund, the Shareholders’ Representative will distribute any remaining Shareholders’ Representative Funds to the Effective Time Holders in accordance with each such holder’s Pro Rata Share.

1.12 Withholding Taxes. Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable to any current or former Company Securityholder pursuant to this Agreement such amounts as Parent or the Surviving Corporation is required to deduct or withhold therefrom under the Code or under any provision of state, local or foreign Tax law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

1.13 Further Action. If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement and the Escrow Agreement or to vest the Surviving Corporation or Parent with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

5.7 Section 280G Shareholder Approval. The Company shall use its commercially reasonable efforts to obtain the approval by such number of Company Shareholders as is required by the terms of Section 280G(b)(5)(B) so as to render the parachute payment provisions of Section 280G of the Code inapplicable to any and all accelerated vesting payments, benefits, options and/or stock provided pursuant to agreements, Contracts or arrangements that might otherwise result, separately or in the aggregate, in the payment of any amount and/or the provision of any benefit that would not be deductible by reason of Section 280G of the Code, with such shareholder vote to be obtained in a manner which satisfies all applicable requirements of Section 280G(b)(5)(B) of the Code and the regulations promulgated thereunder.

The parties recognize and agree that the representations and warranties also operate as bargained for promises and risk allocation devices and that, accordingly, any party’s knowledge, and the waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, shall not affect the right to indemnification or payment of Damages pursuant to this Article 9, or other remedy based on such representations, warranties, covenants, and obligations.

(c) Notwithstanding anything herein to the contrary, the representations and warranties of the Company contained in this Agreement shall, for purposes of the indemnifying parties’ obligations pursuant to this Article 9, be deemed to be made as of the date of this Agreement and as of the Closing Date (except to the extent any such representation or warranty expressly speaks of an earlier date).

(i) any inaccuracy in or breach of any representation or warranty of the Company set forth in this Agreement, the Company Disclosure Schedule, the Company Compliance Certificate or any other document, certificate, schedule or instrument executed and delivered in connection herewith (in each case, without giving effect to any “Knowledge” qualification contained or incorporated directly or indirectly in Section 2.17, but only as such qualifications relate to actions or inactions by Administaff);

(ii) any breach of any covenant or obligation of the Company set forth in this Agreement (including the covenants set forth in Articles 4 and 5), the Company Disclosure Schedule, the Company Compliance Certificate or any other document, certificate, schedule or instrument executed and delivered in connection herewith;

(vii) any failure of the Fundamental Representations to be true and correct.

(b) In the event the Surviving Corporation suffers, incurs or otherwise becomes subject to any Damages as a result of or in connection with any inaccuracy in or breach of any representation, warranty, covenant or obligation, then (without limiting any of the rights of the Surviving Corporation as an Indemnitee) Parent shall also be deemed, by virtue of its ownership of the stock of the Surviving Corporation, to have incurred Damages as a result of and in connection with such inaccuracy or breach but in either case the total amount both Parent and the Surviving Corporation may recover shall not exceed the amount of actual Damages.

(c) In determining the amount of Damages (but not the breach thereof) for which the Indemnitees are entitled to be indemnified pursuant to Section 9.2(a)(i) for a breach of, or inaccuracy in, any representation or warranty, any materiality or Material Adverse Effect standard contained in the applicable representation or warranty shall be disregarded.

(c) If any Indemnitee is entitled to indemnification pursuant to clauses (v) through (vii) of Section 9.2(a), after Parent has exhausted or made claims upon all amounts in the Escrow Fund (after taking into account all other claims for indemnification from the Escrow Fund by the Indemnitees), each Effective Time Holder shall be liable for such holder’s Pro Rata Share of the amount of any Damages resulting from such claims.

(e) Nothing in this Agreement shall preclude any party hereto from seeking injunctive relief or specific performance with respect to any covenant, agreement or obligation of the Company contained in this Agreement.

9.6 Defense of Third Party Claims.

(a) In the event of the assertion or commencement by any Person of any claim or Legal Proceeding (whether against the Surviving Corporation, against Parent or against any other Person) with respect to which any of the Indemnitees may be entitled to indemnification or any other remedy pursuant to this Article 9, Parent shall promptly give the Shareholders’ Representative and the Escrow Agent written notice of such claim or Legal Proceeding (a “ Claim ”); provided, however , that any failure on the part of Parent to so notify the Shareholders’ Representative shall not limit any of the Indemnitees’ rights to indemnification under this Article 9 (except to the extent such failure materially prejudices the defense of such Legal Proceeding).

(b) Within 30 days of delivery of such written notice, the Shareholders’ Representative may elect (by written notice delivered to Parent) to take all necessary steps to properly contest any Claim involving third parties or to prosecute such Claim to conclusion or, subject to Section 9.6(d), settlement. If the Shareholders’ Representative makes the foregoing election, an Indemnitee will have the right to reasonably participate at its own expense in all proceedings. If the Shareholders’ Representative does not make such election within such period or fails to diligently contest such Claim after such election, then the Indemnitee shall be free to handle the prosecution or defense of any such Claim, and will take all necessary steps to contest the Claim involving third parties or to prosecute such Claim to conclusion or, subject to Section 9.6(d), settlement, and will notify the Shareholders’ Representative of the progress of any such Claim, will permit the Shareholders’ Representative, at the sole cost of the Shareholders’ Representative, to reasonably participate in all proceedings and will provide the Shareholders’ Representative with reasonable access to all relevant information and documentation relating to the Claim and the prosecution or defense thereof. In

any case, the party not in control of the Claim will reasonably cooperate with the other party in the conduct of the prosecution or defense of such Claim.

(c) Notwithstanding the foregoing but subject to Section 9.6(d), if a Claim includes Damages equal to an amount in excess of the value of the Escrow Fund on the date of the Claim, or relates to any Taxes, Proprietary Rights or other intellectual property issues, or involves any action by any Governmental Body, Parent shall have the right, at its election, to proceed with the defense of such Claim on its own.

(d) Neither party will compromise or settle any such Claim without the written consent of either Parent (if the Shareholders’ Representative defends the Claim) or the Shareholders’ Representative (if Parent or other Indemnitees defend the Claim). Notwithstanding anything in this Agreement to the contrary, Parent may withhold its consent to any settlement that does not include a full general release of all the claims against the Indemnitees from all parties to the litigation or that requires Parent or any of its Affiliates to perform any covenant or refrain from engaging in any activity; provided that such consent may not be unreasonably withheld, delayed or conditioned.

(e) If the Shareholders’ Representative does not elect to contest any Claim or Legal Proceeding pursuant to Section 9.6(b), and Parent proceeds with the defense of any such Claim, all reasonable expenses relating to the defense of such Claim shall be satisfied out of the Escrow Fund in the manner set forth in the Escrow Agreement.

9.7 Exercise of Remedies; Tax Treatment.

(a) No Indemnitee (other than Parent or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement or under the Escrow Agreement unless Parent (or any successor thereto or assign thereof) shall have consented to the assertion of such indemnification claim or the exercise of such other remedy.
