Each such Company Option so assumed by Parent under this Agreement and converted into an option (a “Parent Option”) for shares of Common Stock, par value $0.01, of Parent (“Parent Common Stock”) will continue to have, and be subject to, the same terms and conditions of such options immediately prior to the Effective Time (including, without limitation, any repurchase rights or vesting provisions), except that: (i) the number of shares of Parent Common Stock for which each such Company Option will be exercisable shall be the product obtained by multiplying (1) the quotient obtained by dividing (x) the Per Option Value by (y) the average of the closing sale prices of Parent Common Stock on the Nasdaq National Market for the ten (10) consecutive trading days ending with the trading day that immediately precedes the Closing Date (the “Average Parent Stock Price”) by (2) the number of shares of Company Common Stock subject to the corresponding Company Option immediately prior to the Effective Time, rounded down to the nearest whole number of shares; and (ii) the per share exercise price of any such assumed Company Option shall be equal to the quotient obtained by dividing (A) the exercise price per share at which such Company Option was exercisable immediately prior to the Effective Time, by (B) the quotient obtained by dividing (x) the Per Option Value by (y) the Average Parent Stock Price, rounded up to the nearest whole cent.

(ii) Except as expressly set forth in Section 4.11(f), no acceleration of the Company Options shall take place as a result of the consummation of the Merger, and the vesting terms of the Parent Options shall be identical to the vesting terms of the Company Options. In all other respects, the Parent Options will be governed by the terms of the assumed Company Stock Plan and the Company’s applicable option agreement thereunder. Reasonably promptly after the Effective Time, and in any event within 10 Business Days after the Effective Time, the Parent Options will be covered by a registration statement on Form S-8 under the Securities Act, subject to Parent’s receipt of any necessary third-party auditor consents.

(iii) Each Expiring Unvested Company Option outstanding but not exercised as of immediately prior to the Effective Time shall be cancelled without any consideration effective at the Effective Time, and the holder thereof shall have no further rights on account thereof or any claim against the Company, Parent, the Merger Sub or any other Person on account of such cancellation.

(iv) Each Company Warrant outstanding but not exercised immediately prior to the Effective Time shall be cancelled without any consideration effective at the Effective Time, and the holder thereof shall have no further rights on account thereof or any claim against the Company, Parent, the Merger Sub or any other Person on account of such cancellation.

(v) Following the Effective Time, Parent will be able to grant stock awards, to the extent permissible by applicable law and Nasdaq regulations, under the terms of the Company Stock Plan or the terms of another plan adopted by Parent to issue the reserved but unissued shares of Company Common Stock under such Company Stock Plan and the shares that would otherwise return to such Company Stock Plan pursuant to the cancellation, termination or expiration of awards granted thereunder or upon the repurchase of shares previously acquired with respect to awards granted thereunder, except that (i) stock covered by such awards will be shares of Parent Common Stock, and (ii) all references to a number of shares of Company Common Stock will be changed to reference Parent Common Stock.

(f) Withholding Rights; Deductions from Consideration. Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from any payment to any Person under this Agreement or any other Transaction Agreements (i) such amounts as it is required to deduct and withhold with respect to the making of such payment or any other Tax withholding obligation with respect to the Merger or the exercise or settlement of any Company Stock Right or the vesting of restricted stock under the Code or any provision of state, local or foreign Tax Law, and (ii) the amount of any outstanding loans (including any accrued but unpaid interest thereof and any other amounts in respect thereof) owed by such Person to the Company as of the Closing. To the extent that amounts are so withheld or deducted by the Surviving Corporation or by Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by the Surviving Corporation or by Parent, as the case may be. Parent or the Surviving Corporation, as the case may be, shall pay over to the appropriate Governmental Entity any such amounts withheld under clause (i) of this paragraph.

(g) No Further Ownership Rights in Company Capital Stock. The cash amounts, if any, paid or payable upon the surrender for exchange of shares of Company Capital Stock in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Capital Stock. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I.

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

(a) Notwithstanding any provision of this Agreement to the contrary, any shares of Company Capital Stock held by a Stockholder who demands and perfects appraisal rights for such shares in accordance with the DGCL or dissenters’ rights for such shares in accordance with California law, and who, as of the Effective Time, has not effectively withdrawn or lost such appraisal rights or dissenters’ rights (collectively, “Dissenting Shares”), shall not be converted into or represent the right to receive any portion of the Merger Consideration pursuant to Section 1.6, but the holder thereof shall only be entitled to such rights as are granted by the DGCL or California law.

(b) If any Stockholder who holds Dissenting Shares as of the Effective Time effectively withdraws or loses (through passage of time, failure to demand or perfect, or otherwise) the right to demand and perfect appraisal rights under the DGCL or dissenters’ rights under California law, as applicable, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares that were Dissenting Shares shall automatically be converted into and represent only the right to receive any portion of the Merger Consideration pursuant to and subject to Section 1.6 without interest thereon upon surrender of the certificate representing such shares.

(c) The Company shall give Parent (i) prompt notice of any written demands for appraisal of any shares of Company Capital Stock, withdrawals of such demands, and any other instruments or notices served pursuant to the DGCL or California law on the Company and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL or dissenters’ rights under California law. The Company shall not, except with the prior written consent of Parent, voluntarily make or agree to make any payment with respect to any demands for appraisal of Company Capital Stock, or offer to settle any such demands.

(a) Deposit of Funds. At the Closing, Parent shall deposit, for payment to the Participating Holders in accordance with the terms and conditions of this Agreement, an amount equal to the Closing Payment, with U.S. Bank National Association, which shall act as the exchange agent (the “Exchange Agent”) in connection with the Merger. A form of agreement with the Exchange Agent is attached hereto as Exhibit E.

(b) Exchange Procedures. If not delivered previously by the Company, within five (5) Business Days after the Closing, Parent or the Exchange Agent will deliver to each Participating Holder: (i) a letter of transmittal (the “Letter of Transmittal”) which shall specify that delivery of a certificate or certificates (the “Certificates”) that immediately prior to the Effective Time represented outstanding shares of Company Capital Stock held by such Participating Holder or Derivative Instruments shall be effected, and risk of loss and title to such Certificates and Derivative Instruments shall pass, only upon delivery of such original Certificates and Derivative Instruments to Parent and shall be in such form and have such other provisions as Parent may specify and (ii) instructions for use in effecting the surrender of the Certificates or Derivative Instrument in exchange for the cash amount payable with respect thereto under this Agreement. The Letter of Transmittal shall indicate that applicable withholding Taxes with respect to the vesting of shares of Company Common Stock that are restricted stock will be withheld from the Merger Consideration otherwise payable to each Participating Holder who receives a payment upon the exchange of shares of Company Common Stock that are restricted stock, and that other amounts may be withheld from any Participating Holder in accordance with the terms of this Agreement. Following the Effective Time and delivery to the Exchange Agent of a duly completed and executed Letter of Transmittal, together with surrender of a Certificate (or Certificates) or a Derivative Instrument (or Derivative Instruments) for cancellation, as applicable, (x) the Participating Holder shall be entitled to receive in exchange therefor the portion of the Closing Payment to which such Participating Holder is entitled pursuant to Section 1.6, and (y) the Certificate(s) and Derivative Instrument(s) so surrendered shall be canceled. Following the Effective Time, until so surrendered, each outstanding Certificate and Derivative Instrument that, prior to the Effective Time, represented shares of Company Capital Stock will be deemed from and after the Effective Time, for all purposes, to evidence only the right to receive that portion of the Merger Consideration or other consideration determined in accordance with this Article I.

(c) No Liability. Notwithstanding anything to the contrary in this Section 1.8, none of the Parent, the Surviving Corporation or any party hereto shall be liable for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(d) Lost, Stolen or Destroyed Certificates. In the event any Certificates or Derivative Instruments shall have been lost, stolen or destroyed, Parent shall cause the Exchange Agent to issue in exchange for such lost, stolen or destroyed Certificates, upon the delivery of an indemnity or surety bond, the portion of the Merger Consideration, Parent Options or other consideration required pursuant to Section 1.6. In such event, the Exchange Agent shall forward additional documentation and instructions necessary to be completed in order to effectively surrender the shares or securities represented by such lost, stolen or destroyed Certificate(s) (including instructions relating to the payment by the holder of such lost, stolen or destroyed Certificate of an indemnity or surety bond fee equal to 2% of the cash value of the shares or securities represented by such Certificate and a $60.00 handling fee).

1.9 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger Sub, the officers and directors of the Company and Merger Sub are fully authorized in the name of their respective corporations or otherwise to take, and will take, all such lawful and necessary action.

(a) Subject to the prior termination of this Agreement by the Company pursuant to Section 7 hereof, the Company shall take all action necessary in accordance with this Agreement, Delaware Law, its Company Certificate of Incorporation and its Bylaws to secure the Transaction Stockholder Approvals pursuant to the Company Stockholder Merger Written Consent. The Company’s obligation to secure the Transaction Stockholder Approvals in accordance with this Section 4.9(a) shall not be limited to or otherwise affected by the commencement, disclosure, announcement or submission to Company of any Acquisition Proposal. The Company shall exercise commercially reasonable efforts to obtain an executed Company Stockholder Merger Written Consent from each Company Stockholder that is not a Company Support Stockholder. The Company Support Stockholders shall continue to constitute the voting power of the outstanding shares of the Company necessary to obtain the requisite Transaction Stockholder Approvals.

Notwithstanding the foregoing, prior to execution of the Company Stockholder Merger Written Consent by a sufficient number of Company Stockholders to obtain the Transaction Stockholder Approvals, the Company Board may withhold, withdraw, amend or modify its recommendation to the Company Stockholders if it concludes in good faith (after consultation with its outside legal counsel) that modification or withdrawal of its recommendation is required in order to comply with its fiduciary obligations to the Company Stockholders under Delaware Law due to the receipt of an unsolicited Superior Proposal.

(a) Until the earlier of July 7, 2006, the Effective Time, or the date of termination of this Agreement pursuant to Section 7.1, neither the Company nor any of its officers, directors, Company Board Stockholders, financial advisors, legal advisors, agents or affiliates (collectively, the “Representatives”) will, directly or indirectly, (i) take any action to solicit, initiate, seek, encourage or support any inquiry, proposal or offer from, furnish any information to, or participate in any negotiations with, any corporation, partnership, person or other entity or group (other than discussions with Parent) regarding any (A) acquisition of the Company, (B) merger, consolidation, recapitalization, liquidation or other similar transaction involving the Company, or (C) acquisition or license of any stock or assets (other than ordinary course transactions with customers) of the Company (any of the transactions described in clauses (A) through (C), an “Acquisition Proposal”); or (ii) otherwise cooperate with, facilitate or encourage any effort or attempt by any Person to do or seek, an Acquisition Proposal; provided, however, that the following will not be deemed to be an “Acquisition Proposal”: (1) the grant of securities by the Company to its Employees or consultants in the ordinary course of business if such grant is made pursuant to the Company Stock Plan and is consistent with the Company’s past practices, (2) the issuance of stock by the Company upon the exercise of outstanding securities or upon the conversion of outstanding securities, or (3) the issuance of shares of Series C Preferred Stock by the Company pursuant to the Company’s Series C Preferred Stock Purchase Agreement, dated as of April 6, 2006.

(b) Notwithstanding anything to the contrary set forth herein, until the date on which this Agreement is approved by the required vote of the Company’s Stockholders, this Section 4.10 shall not prohibit the Company or any of its officers, directors, affiliates or employees from furnishing information regarding the Company to, entering into a confidentiality agreement with or entering into discussions with,

any person or group in response to an unsolicited, bona fide, written Acquisition Proposal submitted by such person or group (and not withdrawn) to the extent and so long as: (i) neither the Company nor any of its Representatives has violated any of the restrictions set forth in this Section 4.10; (ii) the Company Board concludes in good faith that such Acquisition Proposal for the Company is reasonably likely to result in a Superior Proposal and, after consultation with its outside legal counsel, that such action is required in order for the Company Board to comply with its fiduciary obligations to the Company’s Stockholders under applicable Laws; (iii) (A) at least two Business Days prior to furnishing any such information to, or entering into discussions or negotiations with, such person or group, subject to the terms of the Confidentiality Agreement, the Company gives Parent written notice of the identity of such person or group and of the Company’s intention to furnish information to, or enter into discussions or negotiations with, such person or group, and (B) the Company receives from such person or group an executed confidentiality agreement containing terms no less favorable to the disclosing party than the terms of the Confidentiality Agreement; and (iv) contemporaneously with furnishing any such information to such person or group, the Company furnishes such information to Parent (to the extent such information has not been previously furnished by the Company to Parent).

(c) If (i) the Company or any Representative of the Company breaches this Section 4.10 and (ii) the Company consummates an Acquisition Proposal (other than with Parent or an affiliate) within one year of the breach of this Section 4.10 or enters into a contract within such one year period with respect to the proposed consummation of an Acquisition Proposal, then the Company agrees to pay to Parent $1,500,000 upon demand by Parent. The Company and Parent agree that, in the event of a breach by the Company or any Representative of the covenants set forth in this Section 4.10, the actual damages resulting from such breach would be difficult to determine and Parent may not have an adequate remedy at law. As a special inducement for Parent to enter into this Agreement, the Company covenants that at no time will it contest the amount of such liquidated damages. The Company and Parent agree that the foregoing liquidated damages represent a reasonable approximation of the damages that will result from such breach, unless any such breach is due to fraud, intentional misrepresentation or willful breach or misconduct. Notwithstanding anything to the contrary in this Agreement, the Company may, prior to receipt of the Transaction Stockholder Approval only, in response to a Superior Proposal received by the Company Board after the date of this Agreement, terminate this Agreement pursuant to Section 7.1(i) and enter into a letter of intent or similar document or any agreement, contract or commitment with respect to such Superior Proposal.

The Hiring Affiliate following the Closing shall be the Surviving Corporation and such Hiring Affiliate may (but is not obligated to) retain the employment of one or more employees of the Company, on terms and conditions that the Hiring Affiliate determines in its sole discretion. At any time before or after the Closing Date, the Hiring Affiliate may contact any Key Employees in connection with preparing, making or determining whether to make offers of new employment with the Hiring Affiliate. The Company shall cooperate with and use its commercially reasonable efforts to assist the Hiring Affiliate in its efforts to secure satisfactory employment arrangements with such employees and to obtain executed Offer Package Agreements from each Key Employee receiving an offer of employment with the Hiring Affiliate. Any offer of employment shall be subject to the Hiring Affiliate’s policies and procedures, including background checks and confirmation of immigration status of each such Employee.

(c) No Right to Continued Employment or Benefits. Neither Parent nor the Hiring Affiliate is under any obligation to offer employment to, hire or retain any Employee, or provide any Employee with any particular benefits, or make any payments or provide any benefits to those Employees whom the Hiring Affiliate chooses not to employ or subsequently terminates.

(d) Termination of Employment with the Company. Prior to the Closing Date, the Company shall terminate all employees who are not Continuing Employees (the “Terminated Employees”), effective as of the Closing Date and will provide Parent with a schedule listing the Terminated Employees and the amounts payable to each.

(a) Conduct of the Company. From this Agreement Date until the Effective Time, the Company shall not make or change any material election in respect of Taxes, adopt or change any accounting

(s) Release of Encumbrances. Parent shall have received evidence satisfactory to it of the release of all Liens on any of the Company’s properties.

(t) Audited Financial Statements. Parent shall have received copies of the consolidated statements of operations, stockholders equity (deficit) and cash flows of the Company audited for the fiscal years ended December 31, 2003, December 31, 2004 and December 31, 2005, accompanied by the unqualified audit report thereon (other than any going concern qualification) of Grant Thornton LLP, and such audited or reviewed financial statements shall not reflect or disclose any change from the corresponding unaudited statements referred to in Section 2.7(a)(i) which Parent reasonably deems material to the Company or its ability to consummate the Merger (other than adjustments for stock compensation, and the beneficial conversion features related to the Company’s outstanding convertible bridge securities and the recording of interest thereon).

(u) Purchase of Shares of Parent Common Stock by Founder Peter Relan. Parent and Founder Peter Relan shall have entered into an agreement pursuant to which such Founder shall be required to use 22.5% of the after-tax Merger Consideration that he receives pursuant to the Merger to purchase shares of Parent Common Stock upon such terms as such parties may mutually agree.

Pacific time on the one year anniversary of the Closing Date (the “Escrow Termination Date”), except, in all cases, with respect to any Loss, claim or breach of which any Indemnified Party shall have provided written notice to the Stockholder Representative prior to such termination.

(b) The representations and warranties of Parent and Merger Sub set forth in this Agreement or in any certificate, document or other instrument delivered by or on behalf of Parent or Merger Sub pursuant to or in connection with this Agreement shall terminate at the Effective Time.

6.2 Indemnification. As an integral term of the Merger, each Participating Holder, severally, shall indemnify, defend and hold harmless Parent, Merger Sub, the Surviving Corporation and each of their officers, directors, employees, members, agents and Affiliates (the “Indemnified Parties”) against any and all claims, losses, liabilities, damages, deficiencies, diminution in value, interest and penalties, costs and expenses, including reasonable attorneys’ fees and expenses, and expenses of investigation and defense (collectively “Losses”) incurred or suffered by any such Indemnified Parties directly or indirectly as a result of, with respect to or in connection with:

(a) the failure of any representation or warranty of the Company (as qualified by the Company Disclosure Schedule) set forth herein or in any certificate, document or other instrument delivered pursuant to or in connection with this Agreement to be true and correct in all respects as of this Agreement Date and as of the Closing Date (disregarding for purposes of this Section 6.2 any “materiality”, “in all material respects” or similar qualification contained therein or with respect thereto for purposes of calculating Losses);

(b) any failure by the Company to fully perform, fulfill or comply in any material respect with any covenant set forth herein or in any certificate, document or other instrument delivered pursuant to or in connection with this Agreement;

(e) any claims by any current or former holder of Company Capital Stock, Company Options, Company Warrants or other Company Stock Rights relating to or arising out of the Merger, this Agreement, the Allocation Certificate, the transactions contemplated hereby or any Person’s status as an equity holder or ownership of equity interests in the Company at any time on or prior to this Agreement Date, including the allocation of the Merger Consideration, whether for breach of fiduciary duty or otherwise, or any claims by any current or former officer, director or stockholder to indemnification by the Company or the Surviving Corporation with respect to any such claims;

(f) regardless of any disclosure on the Company Disclosure Schedule, any “excess parachute payment” (within the meaning of Section 280G(b) of the Code) made by the Company on or prior to the Closing Date or otherwise required to be paid by the Company or the Surviving Corporation pursuant to Company Contracts entered into on or prior to the Closing Date;

(g) any claims by any Person that arise out of acts or omissions by the Company’s present and former directors and officers that constitute either a breach of this Agreement or a breach of fiduciary duty owed by any such persons;

(h) any Company Transaction Expenses in excess of that amount already disclosed and deducted from the Base Amount;

(j) any Deferred Revenue Shortfall not already disclosed and deducted from the Base Amount; and

(k) any claims by any Person that arise out of or due to the Escrow Fund Distribution Preference terms set forth in Section 6.9(b) hereof.

(a) The Participating Holders in the aggregate shall not be liable to indemnify any Indemnified Party for money damages pursuant to Section 6.2 in an aggregate amount in excess of the Escrow Amount in the Escrow Fund, and each Participating Holder individually shall not be liable to indemnify any Indemnified Party for money damages pursuant to Section 6.2 in an aggregate amount in excess of such Participating Holder’s Pro Rata Share of the Escrow Amount in the Escrow Fund. Subject to Section 6.3(c) hereof, no indemnification claim may be made against the Escrow Fund until Parent has Losses of $500,000 (the “Threshold Basket”), after which Parent shall be indemnified for all Losses up to the Escrow Amount from the first dollar; provided, however, that the Threshold Basket shall not apply to Losses pursuant to Section 6.2(c), Section 6.2(d), and Section 6.2(h) through Section 6.2(k). Parent, Merger Sub and the Indemnified Parties agree that the sole and exclusive remedy for money damages for any matters relating to this Agreement and any certificate or instrument delivered pursuant hereto shall be the rights to indemnification set forth in this Article VI.

(b) The representations, warranties, covenants and obligations of the Company, and the rights and remedies that may be exercised by the Indemnified Parties based on such representations, warranties, covenants and obligations, will not be limited or affected by any investigation conducted by

Parent or Merger Sub or any agent of Parent or Merger Sub with respect to, or any knowledge acquired (or capable of being acquired) by Parent or Merger Sub or any agent of Parent or Merger Sub at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to, the accuracy or inaccuracy of or compliance with any such representation, warranty, covenant or obligation. The waiver by Parent or Merger Sub of any of the conditions set forth in Article V will not affect or limit the provisions of this Article VI.

(c) Notwithstanding anything in this Agreement to the contrary, the limitations set forth in this Section 6.3 shall not apply with respect to: (i) fraud, intentional misrepresentation or willful breach or misconduct; or (ii) any equitable remedy, including a preliminary or permanent injunction or specific performance. Notwithstanding anything in this Agreement to the contrary (including the immediately preceding sentence), in no event will the Participating Holders in the aggregate be liable to indemnify any Indemnified Party for money damages in an aggregate amount in excess of the Merger Consideration and each Participating Holder individually shall not be liable to indemnify any Indemnified Party for money damages in an aggregate amount in excess of such Participating Holder’s Pro-Rata Share of the Merger Consideration.

(d) The amount of any Losses for which indemnification is provided hereunder shall be net of any amount recovered by the Indemnified Parties under any insurance policies with respect to such Losses.

(a) Post-Closing Claims. The procedures for making indemnification claims hereunder either against the Escrow Fund after the Closing in accordance with the terms set forth in this Article VI or that are not made against the Escrow Fund after the Closing are set forth in this Section 6.4(a).

(i) Parent may assert a claim for indemnification under this Section 6, (1) if such claim is being made against the Escrow Fund, by delivering to each of the Escrow Agent and the Stockholder Representative at any time on or before the last day of the Escrow Period a written notice signed by an officer of Parent, and (2) if such claim is not being made against the Escrow Fund, by delivering to the Stockholder Representative a written notice signed by an officer of Parent (in each such case, an “Indemnification Claim”), setting forth Parent’s bona fide claim for indemnification pursuant to Section 6.2 which shall include (i) a brief description of the events, circumstances, facts or information supporting such claim for indemnification, (ii) the aggregate dollar amount of Losses with respect to such claim which are then reasonably determinable by Parent (“Determinable Losses”) and (iii) a non-binding preliminary estimate of the aggregate dollar amount of Losses that could arise with respect to such claim that are then reasonably foreseeable (“Additional Estimated Loss Amount”). In the Indemnification Claim, Parent shall identify any Losses that Parent is then aware are subject to third-party claims against Parent in a litigation or arbitration.

(ii) If any Indemnification Claim is agreed to by the Stockholder Representative, or if the Stockholder Representative has not contested such Indemnification Claim by written notice to Parent (and to the Escrow Agent for any claims made against the Escrow Fund) within 20 Business Days after receipt of such Indemnification Claim (the “Response Period”), then the Escrow Agent (for any claims made against the Escrow Fund) or the Participating Holders (for any claims not made against the Escrow Fund), as the case may be, shall promptly pay to Parent the full amount of Determinable Losses set forth in the Indemnification Claim promptly after the earlier of (i) the Stockholder Representative’s delivery to Parent

(and to the Escrow Agent for any claims made against the Escrow Fund) of its written agreement with such Indemnification Claim, or (ii) the expiration of the Response Period, but in no event more than 10 days after such earlier date. The parties agree that any payment of any amount of Determinable Losses will not limit the amount of Additional Estimated Loss Amounts that may subsequently mature into Determinable Losses that Parent may seek to recover or in any way prejudice Parent’s ability to recover any other Losses (whether or not such Losses were or could have been determined to be Additional Estimated Loss Amounts at the time of the delivery of the Indemnification Claim setting forth such Determinable Losses) that may arise as a result of or in connection with the events, circumstances, facts or information that gave rise to such Determinable Losses.

(iii) In the event that the Stockholder Representative delivers a written notice to Parent and the Escrow Agent for any claims made against the Escrow Fund or a written notice to Parent for any claims not made against the Escrow Fund, as the case may be (each, a “Dispute Notice”), disputing all or any portion of the amount of the claimed Determinable Losses (the “Disputed Claims Amount”) during the applicable Response Period, then Parent and the Stockholder Representative shall for a period of not more than 20 Business Days after delivery of such Dispute Notice (the “Resolution Period”) attempt to resolve the dispute. If the Disputed Claims Amount is less than the Determinable Losses claimed in the relevant Indemnification Claim, then the Escrow Agent (for any claims made against the Escrow Fund) or the Participating Holders (for any claims not made against the Escrow Fund), as the case may be, shall promptly, but in no event more than 10 days after the date of the Dispute Notice, pay to Parent the amount by which such Determinable Losses amount exceeds such Disputed Claims Amount.

(iv) If Parent and the Stockholder Representative do not resolve the dispute during the Resolution Period, either party may seek to resolve such dispute in a proceeding brought in any state or federal court located in the County of Dallas within the State of Texas. During the Resolution Period, Parent and the Stockholder Representative shall provide each other with such information, records and material kept in the ordinary course of business in such party’s possession and which such party may disclose without violating confidentiality obligations to third Persons or any privilege, as is reasonably necessary and appropriate in attempting to resolve such Disputed Claims Amount determination, subject to execution of a confidentiality agreement in form and substance reasonably satisfactory to the delivering party.

(b) In the event that the Final Determination (as defined below) is in favor of Parent with respect to all or a portion of a Disputed Claims Amount, promptly after receipt of such Final Determination but in any event no more than 10 days after such receipt, the Escrow Agent (for any claims made against the Escrow Fund) or the Participating Holders (for any claims not made against the Escrow Fund), as the case may be, shall pay to Parent that portion of the Disputed Claims Amount to which Parent is entitled pursuant to the Final Determination (“Payment Amount”). In the event that the Payment Amount exceeds the Disputed Claims Amount, then the Escrow Agent (for any claims made against the Escrow Fund) or the Participating Holders (for any claims not made against the Escrow Fund), as the case may be, shall promptly pay to Parent the amount of such excess. For purposes of this Agreement, the term “Final Determination” means either (i) instructions in writing executed by Parent and the Stockholder Representative or their respective legal representatives, or (ii) an order of a court or arbitrator that has become final and non-appealable.

(i) Promptly after the assertion by any third party of any claim against any Indemnified Party (a “Third-Party Claim”) that, in the judgment of such Indemnified Party, may result in the incurrence by such Indemnified Party of Losses for which such Indemnified Party would be entitled to indemnification pursuant to this Agreement, such Indemnified Party shall deliver to the Stockholder Representative a written notice describing in reasonable detail such Third-Party Claim; provided, however, that no delay on the part of the Indemnified Party in notifying the Stockholder Representative shall relieve the Participating Holders of any liability or obligations hereunder, except to the extent that the Participating Holders have been materially prejudiced thereby, and then only to such extent. The Indemnified Party shall have the right in its sole discretion at any time to conduct the defense of any such Third-Party Claim; provided, however, that (A) the Stockholder Representative shall have the right to receive copies of all pleadings, notices and communications with respect to any Third-Party Claim to the extent that receipt of such documents does not affect any privilege relating to such Indemnified Party and shall be entitled, at the Stockholder Representative’s expense, to participate in, but not conduct the defense of the Third Party Claim or settlement negotiations with respect to the Third-Party Claim, and (B) the Participating Holders shall not be liable to indemnify any Indemnified Party for any settlement of any such Third-Party Claim effected without the prior written consent of the Stockholder Representative, which consent shall not be unreasonably withheld, conditioned or delayed. If any such action or claim is settled with the prior written consent of the Stockholder Representative, or if there be a final judgment for the plaintiff in any such action, the Indemnified Party shall be entitled to indemnification for the amount of any Loss relating thereto.

(ii) Neither the Participating Holders nor the Stockholder Representative shall have any right to settle, adjust or compromise or conduct the defense of any Third-Party Claim without the express written consent of the Indemnified Party against whom the Third-Party Claim has been asserted.

6.5 Merger Consideration Adjustment. The Company, Parent and the Participating Holders agree to treat each indemnification payment pursuant to this Article VI as an adjustment to the Merger Consideration for all Tax purposes and shall take no position contrary thereto unless required to do so by applicable Tax Law pursuant to a determination as defined in Section 1313(a) of the Code.

(a) By virtue of the adoption of this Agreement and the approval of the Merger by the Stockholders, each Participating Holder (regardless of whether or not such Stockholder votes in favor of the adoption of this Agreement and the approval of the Merger, whether at a meeting or by written consent in lieu thereof) hereby initially appoints, as of this Agreement Date, Amos Barzilay (together with his permitted successors, the “Stockholder Representative”), as his, her or its true and lawful agent and attorney-in-fact to enter into any other Transaction Agreement and any transactions contemplated by this Agreement, and to: (i) give and receive notices and communications to or from Parent (on behalf of itself or any other Indemnified Party) or the Escrow Agent relating to this Agreement or any of the transactions and other matters contemplated hereby (except to the extent that this Agreement expressly contemplates that any such notice or communication shall be given or received by such Participating Holders individually); (ii) authorize deliveries to Parent of cash from the Escrow Fund in satisfaction of claims asserted by Parent (on behalf of itself or any other Indemnified Party, including by not objecting to claims thereto); (iii) object to any claims by Parent to the Escrow Fund; (iv) consent or agree to, negotiate, enter into settlements and compromises of, and agree to arbitration and comply

with orders of courts and awards of arbitrators with respect to such claims; (v) assert, negotiate, enter into settlements and compromises of, and agree to arbitration and comply with orders of courts and awards of arbitrators with respect to, any other claim by any Indemnified Party against any such Participating Holder or by any such Participating Holder against any Indemnified Party or any dispute between any Indemnified Party and any such Participating Holder, in each case relating to this Agreement or the transactions contemplated hereby; (vi) amend this Agreement or any other Transaction Agreement or other agreement referred to herein or contemplated hereby; and (vii) take all actions necessary or appropriate in the judgment of the Stockholder Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any Person under any circumstance.

(c) The person serving as the Stockholder Representative may be replaced from time to time by the holders of a majority in interest of the Escrow Fund upon not less than 10 days’ prior written notice to Parent and with Parent’s written consent, which shall not be unreasonably withheld. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall receive no compensation for his services. Notices or communications to or from the Stockholder Representative shall constitute notice to or from each of the Participating Holders.

(d) The Stockholder Representative shall not be liable to any Participating Holder for any act done or omitted hereunder as the Stockholder Representative while acting in good faith and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Participating Holders shall severally indemnify the Stockholder Representative and hold him harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of his duties hereunder. The Stockholder Representative may arrange to receive reimbursement directly from the Participating Holders for any and all expenses, charges and liabilities, including attorneys’ fees, reasonably incurred by the Stockholder Representative in the performance or discharge of his rights and obligations under this Agreement; provided, however, that neither Parent nor the Surviving Corporation shall have any liability with respect to such items. If not paid directly to the Stockholder Representative by the Participating Holders, any such unpaid expenses, charges and liabilities may be recovered by the Stockholder Representative from the cash deposited in the Escrow Fund that is otherwise distributable to the Participating Holders (and not distributed or distributable to any Indemnified Parties or subject to any pending Indemnification Claim) pursuant to the terms hereof, at the time of any such distribution to the Participating Holders after the Escrow Termination Date. Upon written notice to the Escrow Agent and Parent, the Stockholder Representative shall be entitled to recover any such expenses, in an aggregate amount not to exceed $300,000, from the Escrow Fund immediately prior to the distribution of any Escrow Funds to the Participating Holders.

(e) The Stockholder Representative shall have access to relevant information about the Company and the reasonable assistance of the Company’s officers and Employees for purposes of performing his duties and exercising his rights hereunder; provided that the Stockholder Representative shall treat confidentially and not disclose any nonpublic information from or about the Company to anyone (except on a need to know basis to individuals who agree to treat such information confidentially).

(f) Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Stockholder Representative shall constitute a notice or communication to or by, or a decision, action, failure

to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all the Participating Holders and shall be final, binding and conclusive upon each such Participating Holder; and each Indemnified Party and the Escrow Agent shall be entitled to rely upon any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such Participating Holder. Each Indemnified Party and the Escrow Agent are hereby relieved from any liability to any Person for any acts done by them in accordance with any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent or instruction of the Stockholder Representative.

(g) Except for matters that are subject to Section 6.4, and without limiting the generality or effect of Section 6.6(a), any and all claims and disputes between or among any Indemnified Party, the Stockholder Representative or any one or more Participating Holders relating to this Agreement or the transactions contemplated hereby shall in the case of any claim or dispute asserted by or against or involving any such Participating Holder (other than any claim against or dispute with the Stockholder Representative), be asserted or otherwise addressed solely by the Stockholder Representative on behalf of such Participating Holder (and not by such Participating Holder acting on its own behalf).

6.7 Nonexclusivity of Indemnification Remedies. Notwithstanding anything herein to the contrary, the exercise by any Person of any of its rights under this Article VI shall not be deemed to be an election of remedies and shall not be deemed to prejudice, or to constitute or operate as a waiver of, any other right or remedy that such Person may be entitled to exercise, whether under this Agreement, under any other agreement, under any Law, at common law, in equity or otherwise solely with respect to any equitable remedy such as preliminary or permanent injunctions or specific performance.

6.8 No Subrogation. Following the Closing, no Participating Holder shall have any right of indemnification, contribution or subrogation against the Company with respect to any indemnification made by or on behalf of any Participating Holder under Section 6.2 if the Merger and the transactions contemplated by this Agreement are consummated.

(a) Escrow Fund. As soon as practicable after the Effective Time, Parent will deposit the Escrow Amount with the Escrow Agent, such deposit to constitute the Escrow Fund to be governed by the terms set forth herein and at Parent’s cost and expense. The portion of the Escrow Amount contributed with respect to each of the Participating Holders shall be in proportion to the aggregate Merger Consideration to which each such Participating Holder would otherwise be entitled to receive pursuant to Section 1.6. The Escrow Amount shall be allocated to each of the Participating Holders based on their Pro Rata Share.

(b) Escrow Period; Distribution upon Termination of Escrow Periods. Subject to the following requirements, the Escrow Fund shall be in existence immediately following the Effective Time and shall terminate at 5:00 P.M. Pacific time on the Escrow Termination Date (the “Escrow Period”); provided that the Escrow Period shall not terminate with respect to (and only to) such amount that is reasonably necessary to satisfy any unsatisfied claims concerning facts and circumstances existing prior to the termination of such Escrow Period and to the extent specified in any Indemnification Claim delivered to the

Escrow Agent and Stockholder Representative prior to termination of such Escrow Period (“Eligible Claims”). As soon as all Eligible Claims have been resolved pursuant to the terms hereof, the Escrow Agent shall transfer to the Participating Holders the remaining portion of the Escrow Fund, if any, not required to satisfy the Eligible Claims. To the extent the Escrow Fund exceeds the amount of Eligible Claims on or after the Escrow Termination Date, upon receipt by the Escrow Agent of joint written instructions from the Parent and the Stockholder Representative, the Escrow Agent shall transfer to the Participating Holders the amount, if any, of any excess above the amount of the Eligible Claims then remaining in the Escrow Fund. All funds released from the Escrow Fund to the Participating Holders shall be distributed as follows (the “Escrow Fund Distribution Preference”): (i) first, each former holder of the Company Preferred Stock shall receive an amount, in the aggregate, equal to such holder’s Pro Rata Share of the Escrow Amount, (ii) second, if any funds in the Escrow Fund remain following the distributions described in the preceding subparagraph (i) hereof, each former holder of Company Common Stock shall receive an amount equal to the remaining funds to be released from the Escrow Fund multiplied by a quotient obtained by dividing (x) the Closing Payment each such holder received pursuant to Section 1.6 by (y) the total Closing Payment received pursuant to Section 1.6 by all such former holders of Company Common Stock. To the extent that the funds released from the Escrow Fund (together with any funds previously distributed from the Escrow Fund) are not sufficient to distribute to each former holder of Company Preferred Stock the full amount of each such holder’s Pro-Rata Share of the Escrow Amount, all remaining funds released from the Escrow Fund shall be distributed ratably among such holders based on the portion of the Closing Payment each such holder received pursuant to Section 1.6 relative to the total Closing Payment received pursuant to Section 1.6 by all such former holders of the Company Preferred Stock.

(i) The Escrow Agent shall hold and safeguard the Escrow Fund during the Escrow Period, shall treat such fund as a trust fund in accordance with the terms of this Agreement and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof. All income earned on the cash in the Escrow Fund, if any, shall become part of, and be held as an additional portion of the Escrow Fund in proportion to each Participating Holder’s original share of the Escrow Fund. The parties hereto agree that for tax reporting purposes, Parent is the owner of any cash in the Escrow Fund until such cash is distributed in accordance with this Agreement, and that all interest on or other taxable income, if any, earned from the investment of such cash shall be treated for tax purposes as earned by Parent. At the end of Parent’s taxable year, an amount equal to the income earned from the investment of cash contained in the Escrow Fund shall be deemed paid to the Participating Holders, based on each Participating Holder’s Pro Rata Share, and then recontributed by such Participating Holders to the Escrow Fund. The deemed payment represents interest for the deferral of payment of a portion of the Merger Consideration resulting from the escrow arrangement. The Participating Holders shall be responsible for any Taxes due with respect to the deemed payment.

(ii) The Escrow Agent shall invest and reinvest the Escrow Fund at the joint written instructions of Parent and the Stockholder Representative. In the absence of joint written directions from Parent and the Stockholder Representative, the Escrow Fund shall be invested in a U.S. Bank Money Market account. The joint written instructions shall specify that the Escrow Fund shall be invested in any one or combination of the following: (a) readily marketable direct obligations of the government of the United States or any agency or instrumentality thereof or readily marketable obligations unconditionally guaranteed by the full faith and credit of the government of the United States, (b) insured certificates of deposit, of or time deposits with, any commercial bank that issues commercial paper (rated as described in clause (c) below),

is organized under the laws of the United States or any state thereof and has combined capital and surplus of at least $1 billion, (c) commercial paper issued by any corporation organized under the laws of any state of the United States, rated at least “Prime-1” (or then equivalent grade) by Moody’s Investors Services, Inc. or “A-1” (or then equivalent grade) by Standard & Poors, Inc., or (d) money market funds that invest solely in direct obligations of the government of the United States.

(d) Claims Upon Escrow Fund. Subject to the Escrow Fund claim procedures set forth in Section 6.4 hereof, with respect to each Participating Holder, any payments from the Escrow Fund for Indemnification Claims will be made by multiplying the amount of the aggregate payment from the Escrow Fund by such Participating Holder’s Pro Rata Share. Prior to any distribution of funds from the Escrow Fund to Parent, the Participating Holders or the Stockholder Representative, Parent and the Stockholder Representative shall deliver a certificate to the Escrow Agent showing the remaining balance of the funds held in the Escrow Fund after giving effect to such distribution.

(i) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth herein, and any additional written escrow instructions that the Escrow Agent may receive after the date of this Agreement that are signed by an officer of Parent and the Stockholder Representative, and may rely on and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow Agent while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith, provided that the Escrow Agent has exercised reasonable care in the selection of such counsel.

(ii) The Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person, excepting only orders or process of courts of law or arbitrators, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or arbitrators. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(iii) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder absent gross negligence or willful misconduct.

(iv) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent absent gross negligence or willful misconduct.

(v) In performing any duties under the Agreement, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except for gross negligence or willful misconduct on

the part of the Escrow Agent. The Escrow Agent shall not incur any such liability for (A) any act or failure to act made or omitted in good faith, or (B) any action taken or omitted in reliance upon any instrument, including any written statement of affidavit provided for in this Agreement that the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with the legal counsel in connection with Escrow Agent’s duties under this Agreement and shall be fully protected in any act taken, suffered, or permitted by him/her in good faith in accordance with the advice of counsel provided that the Escrow Agent has exercised reasonable care in the selection of such counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any party to this Agreement.

(vi) If any controversy arises between the parties to this Agreement, or with any other party, concerning the subject matter of this Agreement, its terms or conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may hold all documents and funds held in escrow and may wait for settlement of any such controversy by final appropriate legal proceedings. In such event, the Escrow Agent will not be liable for damage. Furthermore, the Escrow Agent may at its option, file an action of interpleader requiring the parties to answer and litigate any claims and rights among themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents and funds held in escrow, except all cost, expenses, charges and reasonable attorneys fees incurred by the Escrow Agent due to the interpleader action and which the parties jointly and severally agree to pay. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liabilities imposed by the terms of this Agreement.

(vii) The parties and their respective successors and assigns agree jointly and severally to indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, attorneys fees, and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of his/her duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter.

(viii) The Escrow Agent may resign at any time upon giving at least thirty (30) days written notice to Parent and the Stockholder Representative; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows: Parent and the Stockholder Representative shall use all reasonable efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If Parent and the Stockholder Representative fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a successor escrow agent authorized to do business in the State of California. The successor escrow agent shall execute and deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers and duties of the predecessor escrow agent as if originally named as escrow agent. The Escrow Agent shall be discharged from any further duties and liability under this Agreement.

(f) Fees. All fees of the Escrow Agent for performance of its duties hereunder shall be paid by Parent. It is understood that the fees and usual charges agreed upon for services of the Escrow Agent shall be considered compensation for ordinary services as contemplated by this Agreement. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not
