ARTICLE II

CONVERSION OF SECURITIES

Section 2.1 Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of capital stock of Target or capital stock of Sub:

    (a) Capital Stock of Sub. Each issued and outstanding share of the capital stock of Sub shall be converted into and become one fully paid and nonassessable share of Common Stock, $0.001 par value, of the Surviving Corporation.

    (b) Cancellation of Acquiror-Owned and Target-Owned Stock. Any shares of Series A Preferred Stock, $0.001 par value, Series B Preferred Stock, $0.001 par value, Series C Preferred Stock, $0.001 par value, and Series D Preferred Stock, $0.001 par value, of Target (taken together, the "Target Preferred Stock"), or shares of Common Stock, $0.001 par value, of Target ("Target Common Stock"), that are owned by Acquiror, Sub, Target or any other direct or indirect wholly-owned Subsidiary (as defined below) of Acquiror or Target shall be canceled and retired and shall cease to exist and no stock of Acquiror or other consideration shall be delivered in exchange. As used in this Agreement, the word "Subsidiary" means, with respect to any other party, any corporation or other organization, whether incorporated or unincorporated, of which (i) such party or any other Subsidiary of such party is a general partner (excluding partnerships, the general partnership interests of which held by such party or any Subsidiary of such party do not have a majority of the voting interest in such partnership) or (ii) at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect

2


    to such corporation or other organization or a majority of the profit interests in such other organization is directly or indirectly owned or controlled by such party or by any one or more of its Subsidiaries, or by such party and one or more of its Subsidiaries.

    (c) Exchange Ratio.

      (i) Subject to Sections 2.2 and 2.4, each issued and outstanding share of Target Common Stock (other than shares to be canceled in accordance with Section 2.1(b) and any Dissenting Shares as defined in and to the extent provided in Section 2.3) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive a fraction of a fully paid and nonassessable share of Acquiror Common Stock (as defined in Section 4.2) equal to the "Exchange Ratio", as defined in and determined in accordance with the provisions of this Section 2.1(c). All such shares of Target Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the shares of Acquiror Common Stock to be issued in consideration therefor upon the surrender of such certificate in accordance with Section 2.4. The number of shares of Acquiror Common Stock to be issued to each Target stockholder shall be determined by multiplying (1) the number of shares of Target Common Stock held by such stockholder (or which will be held by such stockholder upon the conversion of its shares of Target Preferred Stock into Target Common Stock in accordance with the Target Certificate of Incorporation immediately prior to the Effective Time) by (2) the Exchange Ratio, rounded up to the nearest whole share.

      (ii) For purposes of this Agreement, the term "Total Consideration Shares" shall be deemed to mean the quotient obtained by dividing (x) the result obtained by subtracting from $450,000,000 (I) the Aggregate Transaction Expenses (as defined in Section 8.2(r) hereof), (II) any cash amounts or other value transfers in excess of $8,644,000 paid or payable by Target in connection with or as a result of the termination of lease agreement dated April 12, 2000 between Target and TST 555/575 Market, L.L.C. (the "Landlord") relating to Target's proposed premises at 555 Market Street in San Francisco, California (the "555 Market Street Lease Agreement") and (III) any cash amounts or other value transfers paid or payable by Target in connection with or as a result of Target's entering into a Qualified Sublease (as defined below) (other than the remitting to the Landlord of a portion of any net profits realized by Target in connection with the subleasing arrangement pursuant to the terms of the 555 Market Street Lease Agreement), by (y) $131.26667 (the "Average Stock Price"). The "Exchange Ratio" shall be equal to the quotient determined by dividing (x) the Total Consideration Shares, by (y) the sum of (A) the number of shares of Target Common Stock issued and outstanding as of the Effective Time, plus (B) the number of shares of Target Common Stock subject to issuance upon the exercise in full of all Target Options issued and outstanding immediately prior to the Effective Time, whether vested or unvested, plus (C) the number of shares of Target Common Stock issuable upon the conversion of all issued and outstanding shares of Target Preferred Stock immediately prior to the Effective Time. In no event will the total number of shares of Acquiror Common Stock issuable by Acquiror pursuant to the Merger (including shares of Acquiror Common Stock issuable upon exercise of Target Options assumed by Acquiror in the Merger) exceed the Total Consideration Shares. A schedule setting forth the allocation of the Total Consideration Shares among each holder of Target Common Stock, Target Preferred Stock and Target Options based upon the capitalization of Target as of the Effective Time will be prepared by Target and delivered to Acquiror prior to the Closing Date. For purposes of this Agreement, the term "Qualified Sublease" shall refer to one or more subleases covering, when taken together, the entire premises leased by Target under the 555 Market Street Lease Agreement that may be entered into by Target prior to the Effective Time with one or more subtenants, each of which shall be satisfactory to Acquiror in its reasonable discretion, on terms and conditions that shall be satisfactory to Acquiror in its reasonable discretion (which shall include a minimum lease term of

3


      at least five years for each of the subleases and shall include terms to the net effect that Target shall not be obligated to make any payments or other value transfers to any party in connection with the subleasing arrangement (other than the remitting to the Landlord of a portion of any net profits realized by Target in connection with the subleasing arrangement pursuant to the terms of the 555 Market Street Lease Agreement).

      (iii) If, on or after the date of this Agreement and prior to the Effective Time, the outstanding shares of Acquiror Common Stock or Target capital stock shall have been changed into a different number of shares or a different class by reason of any reclassification, split-up, stock dividend or stock combination, then the Exchange Ratio shall be correspondingly adjusted. The Exchange Ratio shall not change as a result of fluctuations in the market price of Acquiror Common Stock between the date of this Agreement and the Effective Time.

    (d) Target Stock Options. At the Effective Time, all then outstanding options, whether vested or unvested ("Target Options"), to purchase Target Common Stock issued under Target's stock option plans identified in Section 3.2(a) will be assumed by Acquiror in accordance with Section 6.4.

    (e) Restricted Shares. Any shares of Target Common Stock that are subject to repurchase by Target in the event the holder thereof ceases to be employed by Target ("Target Restricted Shares") shall be converted into Acquiror Common Stock on the same basis as provided in subsection (c) above and shall be registered in such holder's name, but shall be held by the Surviving Corporation or Acquiror pursuant to the existing agreements in effect on the date of this Agreement. At the Effective Time, Target shall assign all of its rights under such existing agreements to Acquiror. Holders of the Target Restricted Shares, together with a summary of the vesting schedules for such shares, are identified on Schedule 2.1(e) of the Target Disclosure Schedule.

Section 2.2 Escrow Agreement. At the Effective Time or such later time as determined in accordance with Section 2.3(b), Acquiror will, on behalf of the holders of Target Common Stock and Target Preferred Stock, deposit in escrow certificates representing ten percent (10%) of the Total Consideration Shares allocable to Target Common Stock and Target Preferred Stock in the Merger. Such shares shall be held in escrow on behalf of the persons who are the holders of Target Common Stock or Target Preferred Stock in the Merger immediately prior to the Effective Time (the "Former Target Stockholders"), in accordance with the portion of Total Consideration Shares allocable to each such Former Target Stockholder based upon the Exchange Ratios ("Pro Rata Portion"). Such shares (collectively, the "Escrow Shares") shall be held and applied pursuant to the provisions of an escrow agreement (the "Escrow Agreement") to be executed pursuant to Section 7.6. All calculations to determine the number of Escrow Shares to be delivered by each stockholder of the Company into escrow as aforesaid shall be rounded down to the nearest whole share.

Section 2.3 Dissenting Shares.

    (a) Notwithstanding any provision of this Agreement to the contrary, any shares of Target Common Stock or Target Preferred Stock held by a holder who has exercised such holder's appraisal rights in accordance with Section 262 of Delaware Law or, to the extent applicable, Chapter 13 of the California General Corporation Law (the "California Law"), and who, as of the Effective Time, has not effectively withdrawn or lost such appraisal rights ("Dissenting Shares"), shall not be converted into or represent a right to receive Acquiror Common Stock pursuant to Section 2.1, but the holder of the Dissenting Shares shall only be entitled to such rights as are granted by Delaware Law or California Law, as the case may be.

    (b) Notwithstanding the provisions of Section 2.3(a), if any holder of shares of Target Common Stock or Target Preferred Stock who demands his appraisal rights with respect to such shares under Section 2.1 shall effectively withdraw or lose (through failure to perfect or otherwise) his rights to receive payment for the fair market value of such shares under Delaware Law or California Law, as the case may be, then, as of the later of the Effective Time or the occurrence of such event, such holder's shares shall automatically be converted into and represent only the right to receive Acquiror

4


    Common Stock as provided in Section 2.1(c) upon surrender of the certificate or certificates representing such shares; provided that if such holder effectively withdraws or loses his right to receive payment for the fair market value of such shares after the Effective Time, then, at such time Acquiror will deposit in the escrow created pursuant to the Escrow Agreement additional certificates representing such holder's Pro Rata Portion of the Escrow Shares.

    (c) Target shall give Acquiror (i) prompt notice of any written demands for payment with respect to any shares of capital stock of Target pursuant to Section 262 of Delaware Law or Chapter 13 of California Law, as the case may be, withdrawals of such demands, and any other instruments served pursuant to Delaware Law or California Law, as the case may be, and received by the Target and (ii) the opportunity to participate at its own expense in all negotiations and proceedings with respect to demands for appraisal rights under Delaware Law or California Law, as the case may be. Target shall not, except with the prior written consent of Acquiror, voluntarily make any payment with respect to any demands for appraisal rights with respect to Target Common Stock or Target Preferred Stock or offer to settle or compromise any such demands.

Section 2.4 Exchange of Certificates.

    (a) From and after the Effective Time, each holder of an outstanding certificate or certificates ("Certificates") which represented shares of Target Common Stock or Target Preferred Stock immediately prior to the Effective Time shall have the right to surrender each Certificate to Acquiror (or at Acquiror's option, an exchange agent to be appointed by Acquiror), and receive promptly in exchange for all Certificates held by such holder a certificate representing the number of whole shares of Acquiror Common Stock (other than the Escrow Shares) into which the Target Common Stock or Target Preferred Stock evidenced by the Certificates so surrendered shall have been converted pursuant to the provisions of Article II of this Agreement. The surrender of Certificates shall be accompanied by duly completed and executed Letters of Transmittal in such form as may be reasonably specified by Acquiror. Until surrendered, each outstanding Certificate, which prior to the Effective Time represented shares of Target Common Stock or Target Preferred Stock, shall be deemed for all corporate purposes to evidence ownership of the number of whole shares of Acquiror Common Stock into which the shares of Target Common Stock have been converted but shall, subject to applicable appraisal rights under Delaware Law and Section 2.3, have no other rights. Subject to applicable appraisal rights under Delaware Law and Section 2.3, from and after the Effective Time, the holders of shares of Target Common Stock and Target Preferred Stock shall cease to have any rights in respect of such shares and their rights shall be solely in respect of the Acquiror Common Stock into which such shares of Target Common Stock or Target Preferred Stock have been converted. From and after the Effective Time, there shall be no further registration of transfers on the records of Target of shares of Target Common Stock and Target Preferred Stock outstanding immediately prior to the Effective Time.

    (b) If any shares of Acquiror Common Stock are to be issued in the name of a person other than the person in whose name the Certificate(s) surrendered in exchange therefor is registered, it shall be a condition to the issuance of such shares that (i) the Certificate(s) so surrendered shall be transferable, and shall be properly assigned, endorsed or accompanied by appropriate stock powers, (ii) such transfer shall otherwise be proper and (iii) the person requesting such transfer shall pay Acquiror, or its exchange agent, any transfer or other taxes payable by reason of the foregoing or establish to the satisfaction of Acquiror that such taxes have been paid or are not required to be paid. Notwithstanding the foregoing, neither Acquiror nor Target shall be liable to a holder of shares of Target Common Stock or Target Preferred Stock for shares of Acquiror Common Stock issuable to such holder pursuant to the provisions of Article II of this Agreement that are delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

    (c) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, Acquiror shall issue in exchange for such lost, stolen or destroyed Certificate the shares of Acquiror Common

5


    Stock issuable in exchange therefor pursuant to the provisions of Article II of the Agreement. The Board of Directors of Acquiror may in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to provide to Acquiror an indemnity agreement or bond against any claim that may be made against Acquiror with respect to the Certificate alleged to have been lost, stolen or destroyed.

Section 2.5 Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Acquiror Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Acquiror Common Stock represented thereby until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Acquiror Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Acquiror Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Acquiror Common Stock.

Section 2.6 Tax and Accounting Consequences.

    (a) It is intended by the parties hereto that the Merger shall constitute a "reorganization" within the meaning of Section 368 of the Code. The parties hereto adopt this Agreement as a "plan of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Income Tax Regulations.

    (b) It is intended by the parties hereto that the Merger shall qualify for financial accounting treatment as a pooling of interests.

All debts, liabilities, and obligations incurred after the date of the Most Recent Balance Sheet were incurred in the ordinary course of business and are not material both individually and in the aggregate to Target or its business.

      (i) The term "Taxes" shall mean all taxes, however denominated, including any interest, penalties or other additions to tax that may become payable in respect thereof, (A) imposed by any federal, territorial, state, local or foreign government or any agency or political subdivision of any such government, which taxes shall include, without limiting the generality of the foregoing, all income or profits taxes (including but not limited to, federal income taxes and state income taxes), payroll and employee withholding taxes, unemployment insurance, social security taxes, sales and use taxes, ad valorem taxes, excise taxes, franchise taxes, gross receipts taxes, business license taxes, occupation taxes, real and personal property taxes, stamp taxes, environmental taxes, ozone depleting chemicals taxes, transfer taxes, workers' compensation, Pension Benefit Guaranty Corporation premiums and other governmental charges, and other obligations of the same or of a similar nature to any of the foregoing, which are required to be paid, withheld or collected, (B) any liability for the payment of amounts referred to in (A) as a result of being a member of any affiliated, consolidated, combined or unitary group, or (C) any liability for amounts referred to in (A) or (B) as a result of any obligations to indemnify another person.

10


      (ii) The term "Returns" shall mean all reports, estimates, declarations of estimated tax, information statements and returns relating to, or required to be filed in connection with, any Taxes, including information returns or reports with respect to backup withholding and other payments to third parties.

    (b) All Returns required to be filed prior to the date hereof by or on behalf of Target have been duly filed on a timely basis, and such Returns are true, complete and correct in all material respects. All Taxes shown to be payable on such Returns or on subsequent assessments with respect thereto, and all payments of estimated Taxes required to be made prior to the date hereof by or on behalf of Target under Section 6655 of the Code or comparable provisions of state, local or foreign law, have been paid in full on a timely basis or have been accrued on the Most Recent Balance Sheet, and no other Taxes are payable by Target with respect to items or periods covered by such Returns (whether or not shown on or reportable on such Returns). Target has withheld and paid over all Taxes required to have been withheld and paid over prior to the date hereof, and complied with all information reporting and backup withholding requirements, including maintenance of required records with respect thereto, in connection with amounts paid or owing to any employee, creditor, independent contractor, or other third party. There are no liens on any of the assets of Target with respect to Taxes, other than liens for Taxes not yet due and payable or for Taxes that Target is contesting in good faith through appropriate proceedings and for which appropriate reserves have been established on the Most Recent Balance Sheet. Target has not at any time been (i) a member of an affiliated group of corporations filing consolidated, combined or unitary income or franchise tax returns, or (ii) a member of any partnership or joint venture for a period for which the statue of limitations for any Tax potentially applicable as a result of such membership has not expired.

    (c) The amount of Target's liability for unpaid Taxes (whether actual or contingent) for all periods through the date of the Most Recent Balance Sheet does not, in the aggregate, exceed the amount of the current liability accruals for Taxes reflected on the Most Recent Balance Sheet, and the Most Recent Balance Sheet reflects proper accrual in accordance with generally accepted accounting principles applied on a basis consistent with prior periods of all liabilities for Taxes payable after the date of the Most Recent Balance Sheet attributable to transactions and events occurring prior to such date. No liability for Taxes has been incurred (or prior to Closing will be incurred) since such date other than in the ordinary course of business.

No deficiencies exist or have been asserted (either in writing or verbally, formally or informally), and Target has not received notice (either in writing or verbally, formally or informally) that it has not filed a Return or paid Taxes required to be filed or paid. Target is neither a party to any action or proceeding for assessment or collection of Taxes, nor has such event been asserted or threatened (either in writing or orally, formally or informally) against Target or any of its assets. No waiver or extension of any statute of limitations is in effect with respect to Taxes or Returns of Target.

    (g) Target is not, nor has it ever been, a party to any tax sharing agreement.

    (h) Target is not, nor has it been, a United States real property holding corporation within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code, and Acquiror is not required to withhold tax by reason of Section 1445 of the Code.

Section 3.8 Proprietary Rights.

    (a) Target owns all right, title and interest in and to, or otherwise possesses legally enforceable rights, or is licensed to use, all patents, copyrights, technology, software, software tools, know-how, processes, trade secrets, trademarks, service marks, trade names, Internet domain names and other proprietary rights used in the conduct of Target's business as conducted to the date of this Agreement, including, without limitation, the technology, information, databases, data lists, data compilations, and all proprietary rights developed or discovered or used in connection with or contained in all versions and implementations of Target's World Wide Web sites (including www.egroups.com and the other domain names listed in the Target Disclosure Schedule) or any product which has been or is being distributed or sold by Target or currently is under development by Target or has previously been under development by Target (collectively, including such Web sites, the "Target Products"), free and clear of all liens, claims and encumbrances (including without limitation licensing and distribution rights) (all of which rights are referred to as "Target Proprietary Rights"). The Target Disclosure Schedule contains an accurate and complete (i) list of all patents, trademarks (with separate listings of registered and unregistered trademarks), trade names, Internet domain names and registered copyrights in or related to the Target Products or otherwise included in the Target Proprietary Rights and all applications and registration statements therefor, including the jurisdictions in which each such Target Proprietary Right has been issued or registered or in which any such application of such issuance and registration has been filed, (ii) list of all licenses and other agreements with third parties (the "Third Party Licenses") relating to any material patents, copyrights, trade secrets, software, inventions, technology, know-how, processes or other proprietary rights that Target is licensed or otherwise authorized by such third parties to use, market, distribute or incorporate in Target Products

13

All of Target's patents, copyrights, trademarks, trade names or Internet domain name registrations related to or in the Target Products are valid and in full force and effect, and consummation of the transactions contemplated by this Agreement will not alter or impair any such rights. No claims have been asserted or, to Target's knowledge, threatened against Target (and Target is not aware of any claims which are likely to be asserted or threatened against Target or which have been asserted or threatened against others relating to Target Proprietary Rights or Target Products) by any person challenging Target's use, possession, manufacture, sale or distribution of Target Products under any Target Proprietary Rights (including, without limitation, the Third Party Technology) or challenging or questioning the validity or effectiveness of any material license or agreement relating thereto (including, without limitation, the Third Party Licenses) or alleging a violation of any person's or entity's privacy, personal or confidentiality rights. Target knows of no valid basis for any claim of the type specified in the immediately preceding sentence which could in any material way relate to or interfere with the continued enhancement and exploitation by Target of any of the Target Products. None of the Target Products nor the use or exploitation of any Target Proprietary Rights in Target's current business infringes on the rights of or constitutes misappropriation of any proprietary information or intangible property right of any third person or entity, including without limitation any patent, trade secret, copyright, trademark or trade name, and Target has not been sued or named in any suit, action or proceeding which involves a claim of such infringement, misappropriation or unfair competition.

Except with respect to the rights of third parties to the Third Party Technology and no third party has any express right to reproduce, distribute, market or exploit any works or materials of which any of the Target Products are a "derivative work" as that term is defined in the United States Copyright Act, Title 17, U.S.C. Section 101.

    (c) All material designs, drawings, specifications, source code, object code, scripts, documentation, flow charts, diagrams, data lists, databases, compilations and information incorporating, embodying or reflecting any of the Target Products at any stage of their development (the "Target Components") were written, developed and created solely and exclusively by employees of Target without the assistance of any third party or entity or were created by third parties who assigned ownership of their rights to Target by means of valid and enforceable confidentiality and invention assignment agreements, copies of which have been delivered to Acquiror. Target has at all times used commercially reasonable efforts customary in its industry to treat the Target Proprietary Rights related to Target Products and Target Components as containing trade secrets and has not disclosed or otherwise dealt with such items in a manner intended or reasonably likely to cause the loss of such trade secrets by release into the public domain.

    (d) To Target's knowledge, no employee, contractor or consultant of Target is in violation in any material respect of any term of any written employment contract, patent disclosure agreement or any other written contract or agreement relating to the relationship of any such employee, consultant or contractor with Target or, to Target's knowledge, any other party because of the nature of the business conducted by Target or proposed to be conducted by Target. The Target Disclosure Schedule lists all employees, contractors and consultants who have participated in any way in the development of any material portion of the Target Products or the Target Proprietary Rights.

    (e) Each person presently or previously employed by Target (including independent contractors, if any) has executed a confidentiality, non-disclosure and proprietary inventions assignment agreement pursuant to the form of agreement previously provided to Acquiror or its representatives.

14


    (f) No product liability or warranty claims have been communicated in writing to or threatened against Target.

    (g) To Target's knowledge, there is no material unauthorized use, disclosure, infringement or misappropriation of any Target Proprietary Rights, or any Third Party Technology to the extent licensed by or through Target, by any third party, including any employee, former employee or independent contractor of Target. Target has not entered into any agreement to indemnify any other person against any charge of infringement of any Target Proprietary Rights.

    (h) Target has taken all steps customary and reasonable in its industry to protect and preserve the confidentiality and proprietary nature of all Intellectual Property and other confidential information not otherwise protected by patents, patent applications or copyright ("Confidential Information"). All use, disclosure or appropriation by Target or, to the best knowledge of Target, by another party pursuant to rights granted to it by Target, of Confidential Information owned by Target to a third party has been pursuant to the terms of a written agreement between Target and such third party. All use, disclosure or appropriation by Target of Confidential Information not owned by Target has been pursuant to the terms of a written agreement between Target and the owner of such Confidential Information, or is otherwise lawful.

Section 3.9 Employee Benefit Plans.

    (a) The Target Disclosure Schedule lists, with respect to Target and any trade or business (whether or not incorporated) which is treated as a single employer with Target (an "ERISA Affiliate") within the meaning of Section 414(b), (c), (m) or (o) of the Code, (i) all employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), (ii) each loan to a non-officer employee, loans to officers and directors and any stock option, stock purchase, phantom stock, stock appreciation right, supplemental retirement, severance, sabbatical, medical, dental, vision care, disability, employee relocation, cafeteria benefit (Code Section 125) or dependent care (Code Section 129), life insurance or accident insurance plans, programs or arrangements, (iii) all bonus, pension, profit sharing, savings, deferred compensation or incentive plans, programs or arrangements, (iv) other fringe or employee benefit plans, programs or arrangements that apply to senior management of Target and that do not generally apply to all employees, and (v) any current or former employment or executive compensation or severance agreements, written or otherwise, for the benefit of, or relating to, any present or former employee, consultant or director of Target as to which (with respect to any of items (i) through (v) above) any potential liability is borne by Target (together, the "Target Employee Plans").

    (b) Target has delivered to Acquiror or its representatives a copy of each of the Target Employee Plans and related plan documents (including trust documents, insurance policies or contracts, employee booklets, summary plan descriptions and other authorizing documents, and, to the extent still in its possession, any material employee communications relating thereto) and has, with respect to each Target Employee Plan which is subject to ERISA reporting requirements, provided copies of any Form 5500 reports filed for the last three plan years. Any Target Employee Plan intended to be qualified under Section 401(a) of the Code has either obtained from the Internal Revenue Service a favorable determination letter as to its qualified status under the Code, including all amendments to the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or has applied to the Internal Revenue Service for such a determination letter prior to the expiration of the requisite period under applicable Treasury Regulations or Internal Revenue Service pronouncements in which to apply for such determination letter and to make any amendments necessary to obtain a favorable determination. Target has also furnished Acquiror with the most recent Internal Revenue Service determination letter issued with respect to each such Target Employee Plan, and nothing has occurred since the issuance of each such letter which could reasonably be expected to cause the loss of the tax-qualified status of any Target Employee Plan subject to Code Section 401(a).

ARTICLE VI

PRECLOSING AND OTHER COVENANTS OF ACQUIROR AND SUB

Section 6.1 Advice of Changes. Acquiror and Sub will promptly advise Target in writing of any event occurring subsequent to the date of this Agreement which would render any representation or warranty of Acquiror or Sub contained in this Agreement, if made on or as of the date of such event or the Closing Date, untrue or inaccurate in any material respect.

In connection with the assumption by Acquiror of the Target Options pursuant to this Section 6.4(a), Target shall be deemed to have assigned to Acquiror, effective at the Effective Time, Target's right to repurchase unvested shares of Target Common Stock issuable upon the exercise of the Target Options or previously issued upon the exercise of options granted under the Target Option Plan, in accordance with the terms of the Target Option Plan and the related stock option agreements and stock purchase agreements entered into under the Target Option Plan.

    (b) As soon as practicable after the Effective Time, Acquiror shall deliver to the participants in the Target Option Plan appropriate notice setting forth such participants' rights pursuant thereto and the grants pursuant to the Target Option Plan shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 6.4 after giving effect to the Merger). Acquiror shall comply with the terms of the Target Option Plan and the parties intend that, to the extent required by, and subject to the provisions of, such Target Option Plan and Sections 422 and 424(a) of the Code, that Target Options which qualified as incentive stock options prior the Effective Time continue to qualify as incentive stock options after the Effective Time, and this provision shall be interpreted consistent with that intent.

    (c) Acquiror shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Acquiror Common Stock for delivery upon exercise of Target Options assumed in accordance with this Section 6.4. As soon as practicable after the Effective Time and in any event no later than 45 days after the Closing Date, Acquiror shall file a registration statement on Form S-8 (or any successor or other appropriate forms) under the Securities Act or another appropriate form with respect to the shares of Acquiror Common Stock subject to such options and shall use its best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options remain outstanding.

If any employee of Target becomes a participant in any employee benefit plan, program, policy or arrangement of Acquiror, such employee shall be given

29


credit for all service prior to the Effective Time with Target to the extent permissible under such plan, program, policy or arrangement.

The parties shall make no public announcement concerning this Agreement, their discussions or any other memoranda, letters or agreements between the parties relating to the Merger; provided,however, that either of the parties, but only after reasonable consultation with the other, may make disclosure if required under applicable law; and provided further, however, that following execution of this Agreement or consummation of the Merger, Acquiror may make a public announcement regarding the Merger and the integration of Target's business into that of Acquiror.

    (b) Each of Acquiror and Target shall use all reasonable efforts to resolve such objections, if any, as may be asserted by any Governmental Entity with respect to the transactions contemplated by this Agreement under the HSR Act, the Sherman Act, as amended, the Clayton Act, as amended, the Federal Trade Commission Act, as amended, and any other Federal, state or foreign statutes, rules, regulations, orders or decrees that are designed to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade (collectively, "Antitrust Laws"). In connection therewith, if any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as violative of any Antitrust Law, each of Acquiror and Target shall cooperate and use all reasonable efforts vigorously to contest and resist any such action or proceeding and to have vacated, lifted, reversed, or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent (each an "Order"), that is in effect and that prohibits, prevents, or restricts consummation of the Merger or any such other transactions, unless by mutual agreement Acquiror and Target decide that litigation is not

30


    in their respective best interests. The parties hereto will consult and cooperate with one another, and consider in good faith the views of one another, in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection with proceedings under or relating to any Antitrust Laws. Notwithstanding the provisions of the immediately preceding sentence, it is expressly understood and agreed that neither Acquiror nor Target shall be obligated to litigate or contest any administrative or judicial action or proceeding or any Order beyond September 30, 2000. Each of Acquiror and Target shall use all reasonable efforts to take such action as may be required to cause the expiration of the waiting periods under the HSR Act or other Antitrust Laws with respect to such transactions as promptly as possible after the execution of this Agreement; provided, however, that nothing contained herein shall require either party to seek early termination of any such waiting period under the Antitrust Laws.

    (c) Notwithstanding anything to the contrary in Section 7.3(a) or (b), (i) neither Acquiror nor any of it subsidiaries shall be required to divest any of their respective businesses, product lines or assets, or to take or agree to take any other action or agree to any limitation that could reasonably be expected to have a Material Adverse Effect on Acquiror or of Acquiror combined with the Surviving Corporation after the Effective Time or (ii) Target shall not be required to divest any of its respective businesses, product lines or assets, or to take or agree to take any other action or agree to any limitation that could reasonably be expected to have a Material Adverse Effect on Target.

    (d) From the date of this Agreement until the earlier of the Effective Time or the termination of this Agreement, each party shall promptly notify the other party in writing of any pending or, to the knowledge of such party, threatened action, proceeding or investigation by any Governmental Entity or any other person (i) challenging or seeking material damages in connection with this Agreement or the transactions contemplated hereunder or (ii) seeking to restrain or prohibit the consummation of the Merger or the transactions contemplated hereunder or otherwise limit the right of Acquiror or its subsidiaries to own or operate all or any portion of the businesses or assets of Target.

Section 7.4 Pooling Accounting. Target and Acquiror shall each use reasonable good faith efforts, and shall each use its reasonable good faith efforts to cause its respective Affiliates, to cause the business combination to be effected by the Merger to be accounted for as a pooling of interests and to cause such treatment to be accepted by the SEC. Neither Target nor Acquiror shall take any action that would adversely affect the ability of Acquiror to account for the business combination to be effected by the Merger as a pooling of interests. Consistent with the foregoing, Target agrees that, to the extent it is determined that any of its employees, directors or stockholders will receive payments in connection with the Merger that would result in an excise tax to the recipient pursuant to Section 4999 of the Code and result in a nondeductible expense to Target pursuant to Section 280G of the Code, it will not seek the approval of its stockholders to exempt the payments from such excise tax. Schedule 7.4 sets forth those persons who, in Target's reasonable judgment are or may, at any time prior to the Closing Date, be "affiliates" of Target within the meaning of the SEC's Accounting Releases Nos. 130 and 135 (the "Target Affiliates"). Target shall provide Acquiror such information and documents as Acquiror shall reasonably request for purposes of reviewing such list. Target shall use its commercially reasonable efforts to deliver or cause to be delivered to Acquiror on or prior to the Closing from each of the Target Affiliates an executed Affiliate Agreement.

Prior to and following the Closing, each party agrees to cooperate fully with the other parties and to execute such further instruments, documents and agreements and to give such further written assurances, as may be reasonably requested by any other party to better evidence and reflect the transactions described herein and contemplated hereby and to carry into effect the intents and purposes of this Agreement.

Section 7.6 Escrow Agreement. On or before the Effective Time, Acquiror shall, and the parties hereto shall exercise their reasonable good faith efforts to cause the Escrow Agent (as defined in

31


Section 10.2) and the Stockholders' Agents (as defined in Section 10.9), to enter into an Escrow Agreement in substantially the form attached hereto as Exhibit E.

Section 7.7 FIRPTA. Target shall, prior to the Closing Date, provide Acquiror with a properly executed Foreign Investment and Real Property Tax Act of 1980 ("FIRPTA") FIRPTA Notification Letter which states that shares of capital stock of Target do not constitute "United States real property interests" under Section 897(c) of the Code, for purposes of satisfying Acquiror's obligations under Treasury Regulation Section 1.1445-2(c)(3). In addition, simultaneously with delivery of such FIRPTA Notification Letter, Target shall provide to Acquiror, as agent for Target, a form of notice to the Internal Revenue Service in accordance with the requirements of Treasury Regulation Section 1.897-2(h)(2), along with written authorization for Acquiror to deliver such notice form to the Internal Revenue Service on behalf of Target upon the Closing of the Merger.

Section 7.8 Blue Sky Laws. Acquiror shall take such steps as may be necessary to comply with the securities and blue sky laws of all jurisdictions which are applicable to the issuance of the Acquiror Common Stock in connection with the Merger. Target shall use its reasonable good faith efforts to assist Acquiror as may be necessary to comply with the securities and blue sky laws of all jurisdictions which are applicable in connection with the issuance of Acquiror Common Stock in connection with the Merger.

Section 7.9 Other Filings. As promptly as practicable after the date of this Agreement, Target and Acquiror will prepare and file any other filings required under the Exchange Act, the Securities Act or any other Federal, foreign or state securities or blue sky laws relating to the Merger and the transactions contemplated by this Agreement (the "Other Filings"). The Other Filings will comply in all material respects with all applicable requirements of law and the rules and regulations promulgated thereunder. Whenever any event occurs which is required to be set forth in an amendment or supplement to the Other Filings, Target or Acquiror, as the case may be, will promptly inform the other of such occurrence and cooperate in making any appropriate amendment or supplement, and/or mailing to stockholders of Target, such amendment or supplement.

Section 7.10 Qualification of Merger as a Reorganization. It is the intent of the parties to this Agreement that the Merger qualify as a reorganization under Section 368(a) of the Code, and each of Acquiror, Sub, the Target and the Surviving Corporation covenants and agrees not to take any position on any Return or report relating to Taxes inconsistent with such intent. Each of Acquiror, Sub, the Target and the Surviving Corporation agrees not to take any action either before or after the Effective Time that could reasonably be expected to cause the Merger not to be treated as a "reorganization" under Section 368(a) of the Code.

    (d) by Acquiror, by giving written notice to Target, if the Closing shall not have occurred on or before September 30, 2000 by reason of the failure of any condition precedent under Section 8.1 or 8.2 (unless the failure results primarily from a breach by Acquiror of any representation, warranty, or covenant of Acquiror contained in this Agreement or Acquiror's failure to fulfill a condition precedent to closing or other default); provided, however, that if the failure of such condition precedent is due to a request for additional information from a Governmental Entity pursuant to the HSR Act or any other applicable Antitrust Law, such date shall be automatically extended to the 90th day following acknowledgment by such Governmental Entity that Acquiror and Target have complied with such request, but in no event shall such date be later than December 31, 2000; and provided further, however, that if for any reason the Commissioner shall not issue the Permit and the parties instead shall file the Registration Statement with the SEC pursuant to Section 5.1, such date shall be automatically extended to December 31, 2000.

    (e) by Target, by giving written notice to Acquiror, if the Closing shall not have occurred on or before September 30, 2000 by reason of the failure of any condition precedent under Section 8.1 or 8.3 (unless the failure results primarily from a breach by Target of any representation, warranty, or covenant of Target contained in this Agreement or Target's failure to fulfill a condition precedent to closing or other default); provided, however, that if the failure of such condition precedent is due to a request for additional information from a Governmental Entity pursuant to the HSR Act or any other applicable Antitrust Law, such date shall be automatically extended to the 90th day following acknowledgment by such Governmental Entity that Acquiror and Target have complied with such request, but in no event shall such date be later than December 31, 2000; and provided further, however, that if for any reason the Commissioner shall not issue the Permit and the parties instead shall file the Registration Statement with the SEC pursuant to Section 5.1, such date shall be automatically extended to December 31, 2000; and

    (f) by Acquiror, by giving written notice to Target, if the required approvals of the stockholders of Target contemplated by this Agreement shall not have been obtained by reason of the failure to obtain the required consents or votes upon a vote taken by written consent or at a meeting of stockholders, duly convened therefor or at any adjournment thereof.

    ARTICLE X

    ESCROW AND INDEMNIFICATION

Section 10.1 Indemnification. From and after the Effective Time and subject to the limitations contained in Section 10.2, the Former Target Stockholders will, severally but not jointly and pro rata up to but not exceeding their Pro Rata Portion, indemnify Acquiror, Acquiror's current and future affiliates (including the Surviving Corporation), the respective officers, directors, employees, agents, attorneys, accountants, advisors and representatives of such entities and the respective successors and assigns of such entities (collectively, the "Indemnified Parties") and hold the Indemnified Parties harmless against any loss, expense, liability or other damage, including attorneys' fees, to the extent of the amount of such loss, expense, liability or other damage (collectively "Damages") that the Indemnified Parties have incurred by reason of the breach or alleged breach by Target of any representation, warranty, covenant or agreement of Target contained in this Agreement or in the certificates to be delivered pursuant to Sections 8.2(a) and 8.2(b) (without giving effect to any "Material Adverse Effect" or other materiality qualification or any similar qualification contained in or incorporated directly or indirectly in such representation, warranty, covenant or agreement and without giving effect to any update to the Target Disclosure Schedules delivered by Target to Acquiror prior to Closing). In addition, Target shall indemnify and hold the Indemnified Parties harmless against (i) any amount payable out of the Escrow Fund pursuant to Section 9.3(b) in connection with excess Aggregate Transaction Expenses; (ii) any cash amounts or other value transfers paid or payable by Target in excess of $8,644,000 in connection with or as a result of the termination of the 555 Market Street Lease Agreement; (iii) any Damages incurred following the Effective Time by any Indemnified Party in connection with or as a result of the pending claim by France Telecom against Target or a Subsidiary of Target identified on Schedule 3.20 of the Target Disclosure Schedule and (iv) to the extent that Target shall choose to enter into a Qualified Sublease prior to the Effective Time, any cash amounts or other value transfers paid or payable by Target in connection with or as a result of the Qualified Sublease (other than the remitting to the Landlord of a portion of any net profits realized by Target in connection with the subleasing arrangement pursuant to the terms of the 555 Market Street Lease Agreement) and any Damages incurred following the Effective Time through the Escrow Period by any Indemnified Party in connection with the Qualified Sublease. Acquiror, Target and Sub acknowledge and agree, and the Former Target Shareholders, by their adoption of this Agreement, agree that notwithstanding anything to the contrary contained in this Agreement or any other Transaction Document, such indemnification under this Article X shall be the sole and exclusive remedy for any such claim of breach by Target and with respect to those matters noted in the immediately preceding sentence, except in those cases involving fraud or intentional breach on the part of Target.

Section 10.2 Escrow Fund. As security and the sole and exclusive recourse for the indemnities in Section 10.1 and the reimbursement obligations contemplated by Section 9.3(b), as soon as practicable after the Effective Time, the Escrow Shares shall be deposited with U.S. Bank Trust, National Association (or such other institution selected by Acquiror with the reasonable consent of Target) as escrow agent (the "Escrow Agent"), such deposit to constitute the Escrow Fund (the "Escrow Fund") and to be governed by the terms set forth in this Article X and in the Escrow Agreement.

Section 10.3 Damage Threshold. Notwithstanding the foregoing, the Former Target Stockholders shall have no liability under Section 10.1 and Acquiror may not receive any shares from the Escrow Fund unless and until an Officer's Certificate or Certificates (as defined in Section 10.5 below) for an aggregate amount of Acquiror's Damages in excess of $200,000 has been delivered to the Stockholders' Agents and to the Escrow Agent; provided, however, that after an Officer's Certificate or Certificates for an aggregate of $200,000 in Damages has been delivered, Acquiror shall be entitled to receive Escrow Shares equal in value to the full amount of Damages identified in such Officer's Certificate or Certificates; and provided further, however, that $200,000 threshold amount contemplated by this Section 10.3 shall not be applicable

37


to claims made against the Escrow Fund pursuant to clauses (i), (ii) or (iv) of Section 10.1 above, which claims shall be subject to indemnification and reimbursement on a first dollar basis, but shall be applicable to claims made pursuant to clause (iii) of Section 10.1 above.

Section 10.4 Escrow Periods. The Escrow Fund shall terminate upon the first anniversary date of the Closing Date (the period from the Closing Date to the first anniversary of the Closing Date referred to as the "Escrow Period"), provided, however, that the number of Escrow Shares, which, in the reasonable judgment of Acquiror, subject to the objection of the Stockholders' Agents and the subsequent resolution of the matter in the manner provided in Section 10.8, are necessary to satisfy any unsatisfied claims specified in any Officer's Certificate theretofore delivered to the Escrow Agent and the Stockholders' Agents prior to termination of the Escrow Period with respect to Damages incurred or litigation pending prior to expiration of the Escrow Period, shall remain in the Escrow Fund until such claims have been finally resolved.

Section 10.5 Claims Upon Escrow Fund. Upon receipt by the Escrow Agent on or before the last day of the Escrow Period of a certificate signed by any appropriately authorized officer of Acquiror (an "Officer's Certificate"):

      (i) Stating the aggregate amount of Acquiror's Damages or an estimate thereof, in each case to the extent known or determinable at such time; and

      (ii) Specifying in reasonable detail the individual items of such Damages included in the amount so stated, the date each such item was paid or properly accrued or arose, and the nature of the misrepresentation, breach or claim to which such item is related, the Escrow Agent shall, subject to the provisions of Sections 10.3 and 10.8 hereof and of the Escrow Agreement, deliver to Acquiror out of the Escrow Fund, as promptly as practicable, Escrow Shares having a value equal to such Damages all in accordance with the Escrow Agreement and Section 10.6 below. Amounts paid or distributed from the Escrow Fund shall be paid or distributed pro rata among the Holders (as defined in the Escrow Agreement) based upon their respective percentage interests therein at the time.

Section 10.6 Valuation. For the purpose of compensating Acquiror for its Damages pursuant to this Agreement, the value per share of the Escrow Shares which shall be released to Acquiror in respect of a claim for Damages shall be the Average Stock Price.

Section 10.7 Objections to Claims. At the time of delivery of any Officer's Certificate to the Escrow Agent, a duplicate copy of such Officer's Certificate shall be delivered to the Stockholders' Agents (as defined in Section 10.9 below) and for a period of thirty (30) days after such delivery, the Escrow Agent shall make no delivery of Escrow Shares pursuant to Section 10.4 unless the Escrow Agent shall have received written authorization from the Stockholders' Agents to make such delivery. After the expiration of such thirty (30) day period, the Escrow Agent shall make delivery of the Escrow Shares in the Escrow Fund in accordance with Section 10.4, provided that no such delivery may be made if the Stockholders' Agents shall object in a written statement to the claim made in the Officer's Certificate, and such statement shall have been delivered to the Escrow Agent and to Acquiror prior to the expiration of such thirty (30) day period.

Section 10.8 Resolution of Conflicts.

    (a) In case the Stockholders' Agents shall so object in writing to any claim or claims by Acquiror made in any Officer's Certificate, Acquiror shall have thirty (30) days to respond in a written statement to the objection of the Stockholders' Agents. If after such thirty (30) day period there remains a dispute as to any claims, the Stockholders' Agents and Acquiror shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholders' Agents and Acquiror should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the Escrow Shares from the Escrow Fund in accordance with the terms of the memorandum.

38


    (b) If no such agreement can be reached after good faith negotiation, either Acquiror or the Stockholders' Agents may, by written notice to the other, demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Within fifteen (15) days after such written notice is sent, Acquiror (on the one hand) and the Stockholders' Agents (on the other hand) shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The decision of the arbitrators as to the validity and amount of any claim in such Officer's Certificate shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 10.4, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance with such decision.

    (c) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Santa Clara or San Mateo County, California under the commercial rules then in effect of the American Arbitration Association. The non-prevailing party to an arbitration shall pay its own expenses, the fees of each arbitrator, the administrative fee of the American Arbitration Association, and the expenses, including, without limitation, the reasonable attorneys' fees and costs, incurred by the prevailing party to the arbitration.

Section 10.9 Stockholders' Agents.

    (a) Gayle Crowe and Peter Mills shall be constituted and appointed as agents (the "Stockholders' Agents") for and on behalf of the Former Target Stockholders to give and receive notices and communications, to authorize delivery to Acquiror of the Escrow Shares or other property from the Escrow Fund in satisfaction of claims by Acquiror, to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of the Stockholders' Agents for the accomplishment of the foregoing. All actions of the Stockholders' Agents shall be taken jointly, not individually. Such agency may be changed by the holders of a majority in interest of the Escrow Shares from time to time upon not less than ten (10) days' prior written notice to Acquiror. No bond shall be required of the Stockholders' Agents, and the Stockholders' Agents shall receive no compensation for services. Notices or communications to or from the Stockholders' Agents shall constitute notice to or from each of the Former Target Stockholders.

    (b) The Stockholders' Agents shall not be liable for any act done or omitted hereunder as Stockholders' Agent 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 Former Target Stockholders shall severally and pro rata, in accordance with their Pro Rata Portion, indemnify the Stockholders' Agents and hold them harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Stockholders' Agents and arising out of or in connection with the acceptance or administration of their duties hereunder under this Agreement or the Escrow Agreement.

    (c) The Stockholders' Agents shall have reasonable access to information about Target and Acquiror and the reasonable assistance of Target's and Acquiror's officers and employees for purposes of performing their duties and exercising their rights under this Article X, provided that the Stockholders' Agents shall treat confidentially and not disclose any nonpublic information from or about Target or Acquiror to anyone (except on a need to know basis to individuals who agree to treat such information confidentially).

Section 10.10 Actions of the Stockholders' Agents. A decision, act, consent or instruction of the Stockholders' Agents shall constitute a decision of all of the Former Target Stockholders for whom shares of Acquiror Common Stock otherwise issuable to them are deposited in the Escrow Fund and shall be final, binding and conclusive upon each such Former Target Stockholder, and the Escrow Agent and Acquiror may rely upon any decision, act, consent or instruction of the Stockholders' Agents as being the

39


decision, act, consent or instruction of each and every such Former Target Stockholder. The Escrow Agent and Acquiror are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholders' Agents.

Section 10.11 Claims. In the event Acquiror becomes aware of a third-party claim which Acquiror believes may result in a demand against the Escrow Fund, Acquiror shall promptly notify the Stockholders' Agents of such claim, and the Stockholders' Agents and the Former Target Stockholders for whom shares of Acquiror Common Stock otherwise issuable to them are deposited in the Escrow Fund shall be entitled, at their expense, to participate in any defense of such claim. Acquiror shall have the right in its sole discretion to settle any such claim; provided, however, that Acquiror may not effect the settlement of any such claim without the consent of the Stockholders' Agents, which consent shall not be unreasonably withheld. In the event that the Stockholders' Agents have consented to any such settlement, the Stockholders' Agents shall have no power or authority to object to the amount of any claim by Acquiror against the Escrow Fund for indemnity with respect to such settlement in the amount agreed to.
