        Stock that were issuable upon exercise of such Target Option
        immediately prior to the Effective Time multiplied by the Option
        Exchange Ratio (rounded down to the nearest whole number of shares of
        Acquiror Common Stock) and (ii) the per share exercise price for the
        shares of Acquiror Common Stock issuable upon exercise of such assumed

        Target Option was exercisable immediately prior to the Effective Time
        by the Option Exchange Ratio (rounded up to the nearest whole cent).

              (f) RESTRICTED STOCK. Acquiror shall assume Target's
        obligations, and shall be assigned Target's repurchase rights and
        purchase options, under any Restricted Stock Purchase Agreements, the
        terms and conditions of which, including restrictions on Target

        conditions conflict with the terms and conditions of the Acquiror's
        2000 Stock Incentive Plan, the terms and conditions of Acquiror's 2000
        Stock Incentive Plan shall control.

        1.7   RESERVATION OF SHARES. Acquiror will reserve sufficient shares

will be issued in the Merger, but in lieu thereof, each holder of shares of
Target Capital Stock who would otherwise be entitled to a fraction of a share of
Acquiror Common Stock (after aggregating all fractional shares of Acquiror
Common Stock to be received by such holder) shall be entitled to receive from
Acquiror an amount of cash (rounded to the nearest whole cent) equal to the
product of (a) such fraction, multiplied by (b) the Closing Price.

        1.10   DISSENTING SHARES.

              (a) Notwithstanding any provision of this Agreement to the
        contrary, any shares of Target Capital Stock held by a holder who has
        demanded and perfected appraisal rights for such shares in accordance
        with the California Code and who, as of the Effective Time, has not
        effectively withdrawn or lost such appraisal or dissenters' rights
        ("DISSENTING SHARES") shall not be converted into or represent a right
        to receive the applicable Merger Consideration pursuant to Section
        1.6, but the holder thereof shall only be entitled to such rights as

              (b) Notwithstanding the provisions of Section 1.10(a) above, if
        any holder of shares of Target Capital Stock who demands appraisal of
        such shares under the California Code shall effectively withdraw or
        lose (through failure to perfect or otherwise) the right to appraisal,
        then, as of the later of (i) the Effective Time or (ii) the occurrence
        of such event, such holder's shares shall automatically be converted
        into and represent only the right to receive the applicable Merger
        Consideration as provided in Section 1.6, without interest thereon,
        upon surrender to the Exchange Agent of the certificate representing
        such shares in accordance with Section 1.11 of this Agreement.

              (c) Target shall give Acquiror (i) prompt notice of its receipt
        of any written demands for appraisal of any shares of Target Capital

        instruments delivered to Target relating to the Merger and (ii) the
        opportunity to participate in all negotiations and proceedings with

<PAGE>

        equal to the Escrow Amount; (ii) the aggregate amount of Cash
        Consideration payable pursuant to Section 1.6 in exchange for shares
        of Target Capital Stock outstanding immediately prior to the Effective
        Time; and (iii) cash in an amount sufficient to permit the payment of
        cash in lieu of fractional shares pursuant to Section 1.9 (the
        "EXCHANGE FUND").

              (b) EXCHANGE PROCEDURES. As soon as practicable after the
        Effective Time, the Surviving Corporation shall cause to be mailed to
        each holder of record of a certificate or certificates that
        immediately prior to the Effective Time represented outstanding shares
        of Target Capital Stock (the "CERTIFICATES") and which shares were
        converted into the right to receive the applicable Merger
        Consideration pursuant to Section 1.6, (i) a letter of transmittal in
        customary form (which shall specify that delivery shall be effected,
        and risk of loss and title to the Certificates shall pass, only upon
        delivery of the Certificates to the Exchange Agent and shall be in
        such form and have such other provisions as Acquiror may reasonably
        specify) and (ii) instructions for use in effecting the surrender of
        the Certificates in exchange for certificates representing shares of
        Acquiror Common Stock, the holder's portion of the Cash Consideration
        and cash in lieu of fractional shares. Upon surrender of a Certificate
        for cancellation to the Exchange Agent or to such other agent or
        agents as may be appointed by Acquiror, together with such letter of
        transmittal, duly completed and validly executed in accordance with
        the instructions thereto, the holder of such Certificate shall be
        entitled to receive in exchange therefor a certificate representing
        the number of whole shares of Acquiror Common Stock (less the number
        of shares of Acquiror Common Stock to be deposited in the Escrow Fund
        on such holder's behalf pursuant to Article 7 hereof), and the
        holder's portion of the Cash Consideration to which such holder is
        entitled pursuant to Section 1.6, and cash in lieu of fractional
        shares to which such holder is entitled pursuant to Section 1.9, and
        the Certificate so surrendered shall be canceled. Until surrendered,
        each outstanding Certificate that, prior to the Effective Time,
        represented shares of Target Capital Stock will be deemed from and
        after the Effective Time, for all corporate purposes, other than the
        payment of dividends, to evidence the ownership of the number of full
        shares of Acquiror Common Stock into which such shares of Target
        Capital Stock shall have been so converted, the amount of Cash
        Consideration to which such shares are entitled and cash in lieu of
        fractional shares. As soon as practicable after the Effective Time,
        and subject to and in accordance with the provisions of Article 7
        hereof, Acquiror shall, on behalf of the holders of Target Capital
        Stock, cause to be distributed to the Depositary Agent a certificate
        or certificates (in such denominations as may be requested by the
        Depositary Agent) representing that number of shares of Acquiror
        Common Stock equal to the Escrow Amount, which certificate shall be
        registered in the name of the Depositary Agent. Such shares shall be
        vested shares not subject to any repurchase rights, shall be
        beneficially owned by the holders on whose behalf such shares were
        deposited in the Escrow Fund and shall be available to compensate
        Acquiror as provided in Article 7.

              (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF TARGET
        CAPITAL STOCK. No dividends or other distributions declared or made
        with respect to Acquiror Common Stock with a record date on or after
        the Effective Time will be paid to the

                                     -6-

<PAGE>

        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
        applicable law, 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, the amount of dividends or other distributions with
        a record date after the Effective Time theretofore payable (but for
        the provisions of this Section 1.11(c)) with respect to such whole
        shares of Acquiror Common Stock, and 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
        occurring after surrender payable with respect to such whole shares of
        Acquiror Common Stock.

              (d) TRANSFERS OF OWNERSHIP. If any certificate for shares of
        Acquiror Common Stock is to be issued pursuant to the Merger in a name
        other than that in which the Certificate surrendered in exchange
        therefor is registered, it will be a condition of the issuance thereof
        that the Certificate so surrendered will be properly endorsed and
        otherwise in proper form for transfer and that the person requesting
        such exchange will have paid to Acquiror or any agent designated by it
        any transfer or other taxes required by reason of the issuance of a
        certificate for shares of Acquiror Common Stock in any name other than
        that of the registered holder of the Certificate surrendered, or
        established to the satisfaction of Acquiror or any agent designated by
        it that such tax has been paid or is not payable.

              (e) NO FURTHER OWNERSHIP RIGHTS IN TARGET CAPITAL STOCK. The
        Merger Consideration issued upon the surrender for exchange of shares
        of Target Capital Stock in accordance with the terms hereof (including
        any cash in lieu of fractional shares) shall be deemed to have been
        issued in full satisfaction of all rights pertaining to such shares of
        Target Capital Stock, and there shall be no further registration of
        transfers on the records of Target of shares of Target Capital Stock
        that were outstanding immediately prior to the Effective Time. 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 1.

              (f) LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
        certificates evidencing shares of Target Capital Stock shall have been
        lost, stolen or destroyed, the Exchange Agent shall issue the
        applicable Merger Consideration in exchange for such lost, stolen or
        destroyed Certificates, upon the making of an affidavit of that fact
        by the holder thereof; PROVIDED, HOWEVER, that Acquiror or the
        Exchange Agent may, in its discretion and as a condition precedent to
        the issuance thereof, require the owner of such lost, stolen or
        destroyed Certificates to provide an indemnity or deliver a bond in
        such sum as it may reasonably direct as indemnity against any claim
        that may be made against Acquiror or the Exchange Agent with respect
        to the Certificates alleged to have been lost, stolen or destroyed.

              (g) WITHHOLDING RIGHTS. Each of the Surviving Corporation and
        Acquiror shall be entitled to deduct and withhold from the Merger
        Consideration otherwise payable pursuant to this Agreement to any
        holder of a Certificate such amounts as it

                                     -7-

<PAGE>

        is required to deduct and withhold with respect to the making of such
        payment under the Internal Revenue Code and the rules and regulations
        promulgated thereunder, or any provision of any Tax Laws (taking into
        account the certificate to be provided by Target pursuant to Section
        5.8). To the extent that amounts are so withheld by the Surviving
        Corporation or Acquiror, as the case may be, such withheld amounts
        shall be treated for all purposes of this Agreement as having been
        paid to the holder of the shares of Target Capital Stock in respect to
        which such deduction and withholding was made by the Surviving

<PAGE>

               (b) Target has incurred no material liability for Taxes in the
       period after the date of the Target Financial Statements. The unpaid
       Taxes of Target (i) did not, as of the most recent fiscal month end,

       (other than the reserve for deferred taxes established to reflect timing
       differences between book and tax income) set forth on the face of the

       Statements, as adjusted for operations and transactions in the ordinary
       course of business through the most recent fiscal month end, and

       such reserve as adjusted for operations and transactions in the ordinary
       course of business through the Closing Date.

               (c) Target is not a party to any agreement extending the time
       within which to file any Tax Return. Target has never received notice of
       a claim made by a Taxing Authority of any jurisdiction in which Target
       does not file Tax Returns that Target is or may be subject to taxation
       by that jurisdiction.

               (d) Target has withheld and paid all Taxes required to have been
       withheld and paid in connection with amounts paid or owing to any
       employee, creditor or independent contractor.

               (e) Target does not have knowledge of any actions by any Taxing
       Authority in connection with assessing additional Taxes against or in
       respect of it for any past period. There is no dispute or claim
       concerning any Tax Liability of Target either (i) pending, or to
       Target's knowledge, threatened by any Taxing Authority or (ii) of which
       Target is otherwise aware. There are no Liens for Taxes upon the Assets
       and Properties of Target other than Liens for Taxes not yet due.
       Section 2.11(e) of the Target Disclosure Schedule indicates those Tax
       Returns, if any, of Target that have been audited or examined by Taxing
       Authorities, and indicates those Tax Returns of Target that currently
       are the subject of audit or examination. Target has delivered to
       Acquiror complete and correct copies of all federal, state, local and
       foreign income Tax Returns filed by, and all Tax examination reports and
       statements of deficiencies assessed against or agreed to by, Target
       since the fiscal year ended December 31, 1996.

               (f) There are no outstanding agreements or waivers extending the
       statutory period of limitation applicable to any Tax Returns required to
       be filed by, or that include or are treated as including, Target or with
       respect to any Tax assessment or deficiency affecting Target.

               (g) Target has not received any written ruling related to Taxes
       or entered into any agreement with a Taxing Authority relating to Taxes.

               (h) Target has no liability for the Taxes of any Person other
       than Target (i) under Section 1.1502-6 of the Treasury regulations (or
       any similar provision of state, local or foreign Law), (ii) as a
       transferee or successor, (iii) by Contract or (iv) otherwise.

       payments that are not deductible as a result of the provisions set forth
       in Section 280G of the Internal Revenue Code or the treasury regulations
       thereunder or would result in an excise tax to the recipient of any such
       payment under Section 4999 of the Internal Revenue Code.

               (n) There is currently no limitation on the utilization of the

       2.14   PLANS; ERISA.

               (a) Section 2.14(a) of the Target Disclosure Schedule lists each
       Plan. With respect to each Plan, Target has delivered or made available
       to Acquiror a true, complete and correct copy of (i) such Plan (or, if
       not written, a written summary of its material terms) and the most
       recent summary plan description, if any, related to such Plan, (ii) each
       trust agreement or other funding arrangement relating to such Plan, if
       any, (iii) the most recent annual report (Form 5500) filed with the IRS)
       with respect to such Plan (and, if the most recent annual report is a
       Form 5500-R, the most recent Form 5500-C filed with respect to such
       Plan), if such report is required with respect to such Plan, (iv) the

       Plan, if such report or statement is required with respect to such Plan
       and (v) the most recent determination letter, if any, issued by the IRS
       with respect to such Plan and any pending request for such a
       determination letter. Neither Target nor, to Target's knowledge, any
       other person or entity, has any express or implied commitment, whether
       legally enforceable or not, to modify, change or terminate any Plan,
       other than with respect to a modification, change or termination
       required by ERISA or the Internal Revenue Code.

               (b) Each Plan has been administered in all material respects in
       accordance with its terms and all applicable laws, including ERISA and
       the Internal Revenue Code, and contributions required to be made under
       the terms of any of the Plans as of the date of this Agreement have been
       timely made or, if not yet due, have been properly reflected on the
       Target Financial Statements to the extent required. With respect to the
       Plans, no event has occurred and there exists no condition or set of
       circumstances in connection with which Target could be subject to any
       material liability (other than for routine benefit liabilities) under
       the terms of, or with respect to, such Plans under ERISA, the Internal
       Revenue Code or any other applicable Law.

               (c) Target hereby represents that: (i) each Plan which is
       intended to qualify under Section 401(a), 401(k), 401(m) or 4975(e)(6)
       of the Internal Revenue Code has received a favorable determination

       occurred that could reasonably be expected to adversely affect the
       qualified status of any such Plan; (ii) there has been no prohibited
       transaction (within the meaning of Section 406 of ERISA or Section 4975
       of the Internal Revenue Code and other than a transaction


                                     -20-

<PAGE>

       that is exempt under a statutory, administrative or individual
       exemption) with respect to any Plan that could reasonably be expected
       to result in material liability to Target and (iii) each Plan can be
       amended, terminated or otherwise discontinued after the Effective Time
       in accordance with its terms, without liability (other than (A)
       liability for ordinary administrative expenses typically incurred in a
       termination event or (B) if the Plan is pension benefit plan subject to
       Part 2 of Title I of ERISA, liability for the accrued benefits as of
       the date of such termination (if and to the extent required by ERISA)
       to the extent that there are sufficient assets set aside to satisfy
       such liability or (C) liability imposed as a matter of law including,
       without limitation, obligations under COBRA). No suit, administrative
       proceeding, action or other litigation has been brought against Target
       in which Target has been served, and to Target's knowledge none has
       been brought in which Target has not been served, and none is
       threatened, against or with respect to any such Plan, including any
       audit or inquiry by the IRS or United States Department of Labor (other
       than routine benefits claims).

               (d) No Plan is a multiemployer pension plan (as defined in
       Section 3(37) of ERISA) or other pension plan subject to Title IV or
       Part 3 of Title I of ERISA or Section 412 of the Internal Revenue Code
       and neither Target nor any ERISA Affiliate has sponsored or contributed
       to or been required to contribute to a multiemployer pension plan or
       other pension plan subject to Title IV of ERISA. No material liability
       under Title IV of ERISA has been incurred by Target or any ERISA
       Affiliate that has not been satisfied in full, and no condition exists
       that presents a material risk to Target of incurring or being subject
       (whether primarily, jointly or secondarily) to any liability thereunder.
       None of the assets of Target is, or may reasonably be expected to
       become, the subject of any lien arising under ERISA or Section 412(n) of
       the Internal Revenue Code.

               (e) With respect to each Plan that is subject to Title IV or
       Part 3 of Title I of ERISA or Section 412 of the Internal Revenue Code,
       (i) no reportable event (within the meaning of Section 4043 of ERISA,
       other than an event that is not required to be reported before or within
       30 days of such event) has occurred or is expected to occur, (ii) there
       was not an accumulated funding deficiency (within the meaning of
       Section 302 of ERISA or Section 412 of the Internal Revenue Code),
       whether or not waived, as of the most recently ended plan year of such
       Benefit Plan; and (iii) there is no "unfunded benefit liability" (within
       the meaning of Section 4001(a)(18) of ERISA).

               (f) Except as required by Law, no Plan provides any of the
       following retiree or post-employment benefits to any person: medical,
       disability or life insurance benefits. Target and any ERISA Affiliates
       are in material compliance with (i) the applicable requirements of the
       health care continuation and notice provisions of the Consolidated
       Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") and the
       regulations (including proposed regulations) thereunder and (ii) the
       applicable requirements of the Health Insurance Portability and
       Accountability Act of 1996, as amended, and the regulations (including
       the proposed regulations) thereunder.

               (g) PARACHUTE PAYMENTS. Neither the execution of this Agreement
       nor the consummation of any of the transactions contemplated hereby
       (whether alone or upon the occurrence of any additional or further acts
       or events) will (i) result in any obligation or liability (with respect
       to accrued benefits or otherwise) on the part of Target, Acquiror,
       Merger Sub, or the Surviving Corporation, or any of their respective
       Subsidiaries to any Plan, or to any present or former employee,
       director, officer, shareholder, contractor or consultant of Acquiror,
       the Surviving Corporation, or any their respective Subsidiaries or any
       of their dependents, (ii) be a trigger event under any Plan that will
       result in any payment (whether of severance pay or otherwise) becoming
       due to any such present or former employee, officer, director,
       shareholder, contractor, or consultant, or any of their dependents, or
       (iii) accelerate the time of payment or vesting, or increase the amount,
       of any compensation theretofore or thereafter due or granted to any
       employee, officer, director, shareholder, contractor, or consultant of
       Target or any of their dependents.

       2.15   TITLE TO ASSETS. Except for title to Target Intellectual
Property, which is covered by Section 2.16 below, Target is in possession of
and has good and marketable title to all of its properties, interests in
properties and assets, real and personal, owned by it, and with respect to
properties and assets used by Target but not owned by Target, valid leasehold
interests in or valid rights under Contract to use such properties and assets,
free and clear of all Liens of any kind or character, except (a) the lien of
current taxes not yet due and payable and (b) such imperfections of title,
liens and easements as do not and will not (i) materially detract from or
interfere with the use of the properties subject thereto or affected thereby,
or (ii) otherwise materially impair business operations involving such
properties.

               (a) REAL PROPERTY.

                       (i) Section 2.15(a)(i) of the Target Disclosure
Schedule contains a true and correct list of (i) each parcel of real property
leased, utilized and/or operated by Target (as lessor or lessee or otherwise)
(the "LEASED REAL PROPERTY") and (ii) all Liens relating to or affecting any
parcel of real property referred to in clause (i) to which Target is a party.
Target owns no real property other than Target owned leasehold improvements,
if any, on the Leased Real Property.

                       (ii) Subject to the terms of its respective leases,
Target has a valid and subsisting leasehold estate in and the right to quiet
enjoyment of the Leased Real Properties for the full term of the leases
(including renewal periods) relating thereto. Each lease referred to in clause

enforceable in accordance with its terms, of Target and, to Target's
knowledge, of each other Person that is a party thereto, and except as set
forth in Section 2.15(a)(ii) of the Target Disclosure Schedule, there is no,
and Target has not received notice of any, default (or any condition or event
which, after notice or lapse of time or both, would constitute a default)
thereunder. Target does not owe brokerage commissions or finders fees with
respect to any such Leased Real Property, except to the extent that Target may
renew the term of any such lease, in which case, any such commissions and fees
would be in amounts that are reasonable and customary for the spaces so
leased, given their intended use and terms.

                       (iii) Except as disclosed in Section 2.15(a)(iii) of

of Target, there are no proposed changes in any such building codes or zoning
requirements.

                       (iv) True and correct copies of the documents under

               (h) Except as provided in Section 2.16(h) of the Target
       Disclosure Schedule, to the knowledge of Target (without conducting any
       investigation of the patents and patent rights, trademarks (including

       service marks and the like) and trademark rights, copyright rights,
       trade secret rights, or other proprietary rights of any third parties),
       valid and subsisting, and all necessary registration, maintenance,
       renewal fees, annuity fees and taxes in connection with each item of

       maintaining such Registered Intellectual Property. Section 2.16(i)(1) of
       the Target Disclosure Schedule lists all actions that must be taken by
       Target within 180 days from the date hereof, including the payment of
       any registration, maintenance, renewal fees, annuity fees and taxes or

       registered the copyright maskwork with the U.S. Copyright Office for the
       latest version of each product or technology of Target that constitutes

       Target has obtained a valid and enforceable assignment sufficient to
       irrevocably transfer all rights in such Intellectual Property (including
       the right to seek past and future damages with respect to such
       Intellectual Property) to Target and, in accordance with applicable

       Disclosure Schedule, there are no Contracts or Licenses between Target
       and any other Person with respect to Target Intellectual Property under
       which there is any dispute known to Target regarding the scope of such
       Contract or License, or performance under such Contract or License,
       including with respect to any payments to be made or received by Target
       thereunder.

               (k) Except as provided in Section 2.16(k) of the Target
       Disclosure Schedule, to the best knowledge of Target (without conducting
       any investigation of the patents and patent rights, trademarks
       (including trade names, service marks and the like) and trademark
       rights, copyright rights, trade secret rights, or other proprietary
       rights of any third parties), no Person is infringing or
       misappropriating any Target Intellectual Property.

               (l) Target has taken commercially reasonable steps to protect
       Target's rights in material confidential information and trade secrets
       of Target or provided by any other Person to Target subject to a duty of
       confidentiality. Without limiting the generality of the foregoing,
       Target has, and uses commercially reasonable efforts to enforce, a
       policy requiring each employee, consultant and independent contractor to
       execute proprietary information, confidentiality and invention and
       copyright assignment agreements substantially in the form set forth in
       Section 2.16(l) of the Target Disclosure Schedule, and all current and
       former employees, consultants and independent contractors of Target have
       executed such an agreement. Copies of all such agreements have been
       provided to Acquiror or made available to Acquiror for review.

               (m) No Target Intellectual Property or product, technology or
       service of Target is subject to any pending or, to Target's knowledge,
       threatened Order or Action or Proceeding against Target, or, to Target's
       knowledge (without conducting any investigation of the patents and
       patent rights, trademarks (including trade names, service marks and the
       like) and trademark rights, copyright rights, trade secret rights, or
       other proprietary rights of any third parties), pending or threatened
       Order or Action or Proceeding against any third party, that restricts,
       or that is reasonably expected to restrict in any manner, the use,
       transfer or licensing of any Target Intellectual Property by Target or
       that may affect the validity, use or enforceability of such Target
       Intellectual Property.

               (n) Except as set forth in Schedule 2.16(n) of the Target
       Disclosure Schedule, there have been no material Year 2000 Compliance
       problems with any of computer hardware, software, databases, automated
       systems and other computer and telecommunication equipment owned or used
       by Target ("SYSTEMS") or any products or services designed,
       manufactured, distributed or sold by Target ("PRODUCTS OR SERVICES").
       "YEAR 2000 COMPLIANCE" means, with respect to the Systems, Products or
       Services or other equipment or materials in question, that they have
       been used in 2000 and are expected to continue to operate, either on a
       stand-alone basis or by

       interacting or interoperating with third-party software, without error
       relating to the processing, calculating, comparing, sequencing or other
       use of date-related data.

               (o) Neither this Agreement nor any transactions contemplated by
       this Agreement will result in Acquiror's granting any rights or licenses
       with respect to the Intellectual Property of Acquiror to any Person
       pursuant to any Contract to which Target is a party or by which any of
       its Assets and Properties are bound.

               (p) Section 2.16(p) of the Target Disclosure Schedule sets forth
       a list of (x) all software that Target has licensed from any third party
       incorporated by Target in its products and (y) a list of all "freeware"
       and "shareware" incorporated into any product now or heretofore shipped
       by Target. Target has all rights necessary to the use of such software,
       "freeware" and "shareware".

               (q) Target's current products comply, and Target's past products
       have complied, in all material respects with the applicable feature
       specifications and performance standards (including all referenced
       applicable standards) set forth in Target's product data sheets at the
       times such products were manufactured and sold. All product performance
       comparisons heretofore furnished by Target to customers or Acquiror are
       accurate in all material respects as of the dates so furnished (except
       that, in the case of product performance comparisons made as of a
       specified earlier date, such comparisons shall be accurate as of such
       specified earlier date, and, in the case of product performance
       comparisons superseded by a subsequent product performance comparison
       furnished to the customer before the customer's acquisition of a license
       on the product covered by the superseded comparison, the superseding
       comparison shall be accurate in all material respects and the superseded
       comparison shall be disregarded).

               (a) The insurance policies listed in Section 2.18(a) of the
       Target Disclosure Schedule, (i) in light of the business, operations and
       Assets and Properties of Target are in amounts and have coverages that

       and operations and having similar Assets and Properties and (ii) are in
       amounts and have coverages as required by any Contract to which Target

       benefit of Target. The insurance coverage provided by the policies set

       is in default thereunder, and Target has no knowledge of any reason or
       state of facts that could reasonably be expected to lead to the
       cancellation of such policies.

<PAGE>

               (b) Section 2.18(b) of the Target Disclosure Schedule contains a
       list of all material claims made under any insurance policies covering
       Target in the last two years. Target has not received notice that any
       insurer under any policy referred to in this Section is denying
       liability with respect to a claim thereunder or defending under a
       reservation of rights clause. Target has, in the reasonable judgment of
       Target, in light of its business, location, operations and Assets and
       Properties, maintained, at all times, without interruption, appropriate
       insurance, both in scope and amount of coverages.

       2.19   AFFILIATE TRANSACTIONS.

               (a) Except as disclosed in Section 2.9(e) or Section 2.19(a) of
       the Target Disclosure Schedule, (i) there are no Contracts or
       Liabilities between Target, on the one hand, and (A) any current or
       former officer, director, shareholder, or to Target's knowledge, any
       Affiliate or Associate of Target or (B) any Person who, to Target's
       knowledge, is an Associate of any such officer, director, shareholder or
       Affiliate, on the other hand, (ii) Target does not provide or cause to
       be provided any assets, services or facilities to any such current or
       former officer, director, shareholder, Affiliate or Associate,

       shareholder, Affiliate or Associate provides or causes to be provided
       any assets, services or facilities to Target and (iv) Target does not
       beneficially own, directly or indirectly, any Investment Assets of any
       such current or former officer, director, shareholder, Affiliate or
       Associate.

       Disclosure Schedule, each of the Contracts and Liabilities listed in
       Section 2.19(a) of the Target Disclosure Schedule were entered into or
       incurred, as the case may be, on terms no less favorable to Target (in
       the reasonable judgment of Target) than if such Contract or Liability
       was entered into or incurred on an arm's-length basis on competitive
       terms. Any Contract to which Target is a party and in which any director
       of Target has a financial interest in such Contract was approved by a
       majority of the disinterested members of the board of directors of
       Target and/or shareholders of Target, as the case may be.

       2.20   EMPLOYEES; LABOR RELATIONS.

               (a) Target is not a party to any collective bargaining agreement
       and there is no unfair labor practice or labor arbitration proceedings
       pending with respect to Target, or, to the knowledge of Target,
       threatened, and there are no facts or circumstances known to Target that
       could reasonably be expected to give rise to such complaint or claim.

               (b) All employees of Target are employed at will, and no
       employees of Target are represented by a union. Section 2.20(b)(i) of
       the Target Disclosure Schedule sets forth, individually and by category,
       the name of each officer, employee and consultant, together with such
       person's position or function, annual base salary or wage and any
       incentive, severance or bonus arrangements with respect to such person.
       Except as described in Section 2.20(b)(ii) of the Target Disclosure
       Schedule,

       the completion of the transactions contemplated by this Agreement will
       not result in any payment or increased payment becoming due from Target
       to any current or former officer, director, or employee of, or
       consultant to, Target, and to the knowledge of Target no employee of
       Target has made any threat, or otherwise revealed an intent, to
       terminate such employee's relationship with Target, for any reason,
       including because of the consummation of the transactions contemplated
       by this Agreement. Target is not a party to any agreement for the
       provision of labor from any outside agency. To the knowledge of Target,

       outside agencies, if any, with regard to employees assigned to work for
       Target, and no claims by any governmental agency with regard to such
       employees.

               (c) Since May 31, 1997, there have been no federal or state
       claims based on sex, sexual or other harassment, age, disability, race
       or other discrimination or common law claims, including claims of
       wrongful termination, by any employees of Target or by any of the
       employees performing work for Target but provided by an outside
       employment agency, and there are no facts or circumstances known to
       Target that could reasonably be expected to give rise to such complaint
       or claim. Target has complied in all material respects with all laws
       related to the employment of employees and, except as set forth in
       Section 2.20(c) of the Target Disclosure Schedule, since May 31, 1997
       Target has not received any notice of any claim that it has not complied
       in any material respect with any Laws relating to the employment of
       employees, including without limitation, any provisions thereof relating

        4.2   NO SOLICITATION. Until the earlier of the Effective Time and the

directors, employees, shareholders, attorneys, investment advisors, agents,
representatives, Affiliates or Associates (collectively, "REPRESENTATIVES") to
(directly or indirectly), take any of the following actions with any Person
other than Acquiror and its designees: (a) solicit, encourage, initiate,
entertain, accept receipt of, review or encourage any proposals or offers from,
or participate in or conduct discussions with or engage in negotiations with,
any Person relating to any offer or proposal, oral, written or otherwise, formal
or informal (a "COMPETING PROPOSED TRANSACTION"), with respect to any possible
Business Combination with Target, (b) provide information with respect to Target
to any Person, other than Acquiror, relating to (or which Target believes would

Target, (c) agree to, enter into a Contract with any Person, other than
Acquiror, providing for, or approve a Business Combination with Target ,

such action. Target shall immediately cease and cause to be terminated any such
contacts or negotiations with any Person relating to any such transaction or
Business Combination. In addition to the foregoing, if Target receives prior to
the Effective Time or the termination of this Agreement any offer or proposal
(formal or informal, oral, written or otherwise) relating to, or any inquiry or
contact from any Person with respect to, a Competing Proposed Transaction,
Target shall immediately notify Acquiror thereof and provide Acquiror with the
details thereof, including the identity of the Person or Persons making such
offer or proposal, and will keep Acquiror fully informed on a current basis of
the status and details of any such offer or proposal and of any modifications to
the terms thereof; provided, however, that this provision shall not in any way
be deemed to limit the obligations of Target and its Representatives set forth
in the previous sentence. Each of Target and Acquiror acknowledge that this
Section 4.2 was a significant inducement for Acquiror to enter into this
Agreement and the absence of such provision would have resulted in either (i) a
material reduction in the merger consideration


                                    -41-
<PAGE>

to be paid to the shareholders of Target or (ii) a failure to induce Acquiror
to enter into this Agreement.

                              ADDITIONAL AGREEMENTS

        5.1   INFORMATION STATEMENT; PERMIT APPLICATION.

                (a) As soon as practicable after the execution of this
        Agreement, Target shall prepare, with the cooperation of Acquiror, the
        Information Statement for the shareholders of Target to approve this
        Agreement, the California Agreement of Merger and the transactions
        contemplated hereby. Target shall use its best efforts to ensure that
        the Information Statement complies with the California Code and other
        applicable Laws. Each of Acquiror and Target agrees to provide promptly
        to the other such information concerning its business and financial
        statements and affairs as, in the reasonable judgment of the providing
        party or its counsel, may be required or appropriate for inclusion in
        the Information Statement, or in any amendments or supplements thereto,
        and to cause its counsel and auditors to cooperate with the other's
        counsel and auditors in the preparation of the Information Statement.
        Target will promptly advise Acquiror, and Acquiror will promptly advise
        Target, in writing if at any time prior to the Effective Time either
        Target or Acquiror, as applicable, shall obtain knowledge of any facts
        that might make it necessary or appropriate to amend or supplement the
        Information Statement in order to make the statements contained or
        incorporated by reference therein not misleading or to comply with
        applicable law. The Information Statement shall contain the unanimous
        recommendation of the board of directors of Target that Target's
        shareholders approve the Merger and this Agreement and the conclusion of
        the board of directors that the terms and conditions of the Merger are
        advisable and fair and reasonable to, and in the best interests of, the
        shareholders of Target. Anything to the contrary contained herein
        notwithstanding, Target shall not include in the Information Statement
        any information with respect to Acquiror or its affiliates or
        associates, the form and content of which information shall not have
        been approved by Acquiror prior to such inclusion.

                (b) As soon as practicable after the execution of this
        Agreement, Acquiror shall prepare, with the cooperation of Target, and
        file the Permit Application. Acquiror and Target shall each use
        commercially reasonable efforts to cause the Permit Application to
        comply with the requirements of applicable federal and state laws. Each
        of Acquiror and Target agrees to provide promptly to the other such
        information concerning its business and financial statements and affairs
        as, in the reasonable judgment of the providing party or its counsel,
        may be required or appropriate for inclusion in the Permit Application,
        or in any amendments or supplements thereto, and to cause its counsel
        and auditors to cooperate with the other's counsel and auditors in the
        preparation of the Permit Application. Target will promptly advise
        Acquiror, and Acquiror will promptly advise Target, in writing if at any
        time prior to the Effective Time either Target or Acquiror, as
        applicable, shall obtain knowledge of any facts that might make it
        necessary or appropriate to amend or supplement the Permit Application
        in order to make the statements contained or


                                    -42-
<PAGE>

        incorporated by reference therein not misleading or to comply with
        applicable law. Anything to the contrary contained herein
        notwithstanding, Acquiror shall not include in the Permit Application
        any information with respect to Target or its affiliates or associates,
        the form and content of which information shall not have been approved
        by Target prior to such inclusion.

                (c) In the event that the California Permit cannot be obtained
        in time to permit the Closing to occur on or before August 31, 2000,
        then, at Target's election, unless Acquiror shall certify to Target that
        Acquiror believes in good faith that the California Permit can be
        obtained within thirty (30) days after such date, Acquiror and Target
        shall use commercially reasonable efforts to effect the issuance of the
        shares of Acquiror Common Stock to be issued pursuant to Section 1.6 in
        a private placement pursuant to Section 4(2) of the Securities Act on
        terms and conditions that are reasonably satisfactory to Acquiror. The
        parties hereto acknowledge and agree that in such event: (i) as a
        condition to effecting such issuance as a private placement pursuant to
        Section 4(2) of the Securities Act, Acquiror shall be entitled to obtain
        from each shareholder of Target a Shareholder Certificate in the form
        attached hereto as EXHIBIT B (or such other form as shall be reasonably
        satisfactory to Acquiror) (the "SHAREHOLDER CERTIFICATE") and which will
        include an acknowledgement from each such shareholder that Acquiror will
        be relying upon the representations made by such shareholder of Target
        in the applicable Shareholder Certificate in connection with the
        issuance of Acquiror Common Stock to such shareholder, (ii) at the
        Closing, Acquiror and Target shall execute and deliver a backup
        registration rights agreement (the "BACKUP REGISTRATION RIGHTS
        AGREEMENT") granting registration rights with respect to the shares
        subject to terms, conditions, limitations, blackout periods and
        postponement rights reasonably acceptable to the parties; (iii) the
        shares of Acquiror Common Stock so issued pursuant to Section 1.6 will
        not be registered under the Securities Act and will constitute
        "restricted securities" within the meaning of the Securities Act; and
        (iv) the certificates representing the shares of Acquiror Common Stock
        shall bear appropriate legends to identify such privately placed shares
        as being restricted under the Securities Act, to comply with applicable
        state securities laws and, if applicable, to notice the restrictions on
        transfer of such shares.

        5.2   SHAREHOLDER APPROVAL. As soon as practicable following the
completion of the Information Statement and receipt, after the filing of the
Permit Application, of a date for the fairness hearing to be held pursuant to
Section 25142 of the California Code, Target shall mail the Information

Incorporation and By-laws to convene a meeting of the shareholders of Target or
to secure the written consent of its shareholders ("TARGET SHAREHOLDER ACTION")

submit this Agreement to its shareholders for adoption whether or not Target's
board of directors determines at any time subsequent to declaring its
advisability that this Agreement is no longer advisable and recommends that its
shareholders reject it. Target shall consult with Acquiror regarding the date of
Target Shareholder Action and shall not postpone or adjourn (other than for the
absence of a


                                    -43-

Acquiror, which consent shall not be unreasonably withheld. Target shall use
its best efforts to solicit and obtain from shareholders of Target proxies in
favor of the Merger and shall take all other action necessary or advisable to

to this Section 5.3 shall affect or be deemed to modify any representation or
warranty made by Target herein. Materials furnished to Acquiror pursuant to this
Section 5.3 may be used by Acquiror for strategic and integration planning
purposes relating to accomplishing the transactions contemplated hereby.


        5.4  CONFIDENTIALITY. Each of the parties hereto hereby agrees to
keep the existence and terms of this Agreement (except to the extent
contemplated hereby) and such information or knowledge obtained in any
investigation pursuant to Section 5.3, or pursuant to the negotiation and
execution of this Agreement or the effectuation of the transactions
contemplated hereby, confidential; PROVIDED, HOWEVER, that the foregoing
shall not apply to information or knowledge which (a) a party can demonstrate
was already lawfully in its possession prior to the disclosure thereof by the
other party, (b) is generally known to the public and did not become so known
through any violation of Law, or a confidentiality agreement or other
contractual, legal or fiduciary obligation of confidentiality of the
disclosing party or any other party with respect to such information, (c)
became known to the public through no fault of such party, (d) is later
lawfully acquired by such party without confidentiality restrictions from
other sources not bound by applicable confidentiality restrictions, (e) is
required to be disclosed by order of court or Governmental or Regulatory
Authority with subpoena powers (provided that such party shall have provided
the other party with prior notice of such order and an opportunity to object
or seek a protective order and take any other available action) or (f) which
is disclosed in the course of any Action or Proceeding between any of the
parties hereto. The parties acknowledge that Acquiror and Target have
previously executed a non-disclosure agreement dated April 17, 2000 (the
"CONFIDENTIALITY AGREEMENT"), which Confidentiality Agreement shall continue
in full force and effect in accordance with its terms. Without limiting the
foregoing, all information


                                    -44-
<PAGE>

furnished to Acquiror and its officers, employees, accountants and counsel by
Target, and all information furnished to Target by Acquiror and its officers,
employees, accountants and counsel, shall be covered by the Confidentiality
Agreement, and Acquiror and Target shall be fully liable and responsible
under the Confidentiality Agreement for any breach of the terms and
conditions thereof by their respective subsidiaries, officers, employees,
accountants and counsel.

        5.5   EXPENSES. Whether or not the Merger is consummated, all costs,
fees and expenses incurred by Acquiror or Target in connection with the
negotiation and effectuation of the terms and conditions of this Agreement and
the Merger shall be the obligation of the respective party incurring such costs,
fees and expenses; PROVIDED, HOWEVER that in the event the Merger is
consummated, the Surviving Corporation shall be liable for up to $400,000 of the
costs, fees and expenses incurred by Target (including fees and expenses of
legal counsel and accountants) and the costs, fees and expenses of Target in
excess of $400,000 paid or payable by Target in connection with this Agreement
or the Merger shall be the obligation of the Target's shareholders. No later
than the second Business Day prior to Closing, Target shall deliver to Acquiror
an itemized schedule of all costs, fees and expenses incurred by Target with
respect to this Agreement and the Merger (including a reasonable estimate of
costs, fees and expenses through the Closing Date) and such schedule shall be
certified as true, correct and complete by the Chief Financial Officer of Target
(the "TARGET EXPENSE SCHEDULE"). Based on such schedule, Acquiror shall reduce
the number of shares of Acquiror Common Stock issuable in the Merger by the
amount of Target's costs, fees and expenses for which Target's shareholders are
liable pursuant to this Section 5.5 (the "MERGER EXPENSE SET-OFF"). If Acquiror
or the Surviving Corporation receives any invoices and thereafter pays amounts
in excess of the costs, fees and expenses set forth in the Target Expense
Schedule, and the Target Shareholders do not promptly reimburse Acquiror or the
Surviving Corporation therefor, such amounts shall constitute a "Loss"
recoverable by Acquiror from the Escrow Fund pursuant to Article 7 hereof,
without regard to any minimum Loss thresholds. Each party hereto agrees to use
its best efforts to minimize its costs, fees and expenses in connection with the
negotiation and consummation of the transactions contemplated by this Agreement.

company, and that until the transactions contemplated by this Agreement are
public, Target and those whom it advises of this transaction (which shall only

be privy to material inside information; accordingly, Target understands, and
Target has apprised those of its respective officers, directors, shareholders
and agents who know of the potential transaction, of the need for
confidentiality and the potential consequences of any trading in the securities
of Acquiror. Unless otherwise required by Law (including federal and state
securities laws) or, as to Acquiror, by the rules and regulations of the NASD,
prior to the Effective Time, no public disclosure (whether or not in response to
any inquiry) of the existence of any subject matter of, or the terms and
conditions of, this Agreement shall be made by any party hereto unless approved
by Acquiror and Target prior to release; PROVIDED, HOWEVER, that such approval
shall not be unreasonably withheld or delayed. The parties hereto acknowledge
their intent to issue a joint press release simultaneous with the signing of
this Agreement. The joint press release shall provide a brief summary of the
agreement in principal between the parties


                                    -45-
<PAGE>

and the principal closing conditions, including the approval by Target
shareholders and the anticipated closing date.

        5.7   APPROVALS. Each of Target and Acquiror shall use its best efforts
to obtain all Approvals required to be obtained by it from Governmental or
Regulatory Authorities and Target shall use its best efforts to obtain all
Approvals under any of the Contracts or other agreements as may be required in
connection with the Merger (all of such Approvals are set forth in the

thereunder. Acquiror and Target shall provide each other with such assistance
and information as is reasonably required to obtain such Approvals.

        5.8   FIRPTA COMPLIANCE. On or prior to the Closing Date, Target shall

of such statement, Target shall deliver to Acquiror, as agent for Target, a form
of notice to the IRS in accordance with the requirements of Treasury Regulation
Section 1.897-2(h)(2) along with a written authorization for Acquiror to deliver
such notice form to the IRS on behalf of Target upon the consummation of the
Merger.

        5.9   NOTIFICATION OF CERTAIN MATTERS. Target shall give prompt notice
to Acquiror, and Acquiror shall give prompt notice to Target, of (a) the
occurrence or non-occurrence of any event, the occurrence or non-occurrence of
which is likely to cause any representation or warranty of Target or Acquiror,
respectively, contained in this Agreement to be untrue or inaccurate at or prior
to the Closing Date and (b) any failure of Target or Acquiror, as the case may
be, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery
of any notice pursuant to this Section 5.9 shall not limit or otherwise affect
any remedies available to the party receiving such notice.

        5.10   LOCK-UP AGREEMENTS. Target shall cause each person who
immediately prior to the Effective Time holds shares of Target Capital Stock or
holds Target Options or Target Warrants to enter into a Lock-up Agreement with
Morgan Stanley Dean (each, a "Lock-up Agreement") on the same terms and

                                    ARTICLE 7
             SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND
                         AGREEMENTS; ESCROW PROVISIONS

        7.1   SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS.
Notwithstanding any right of Acquiror or Target (whether or not exercised) to
investigate the affairs of Acquiror or Target (whether pursuant to Section 5.3
or otherwise) or a waiver by Acquiror or Target of any condition to Closing set
forth in Article 6, each party shall have the right to rely fully upon the
representations, warranties, covenants and agreements of the other party
contained in this Agreement or in any instrument delivered pursuant to this
Agreement. Except as otherwise provided in Section 9.5, all of the
representations, warranties, covenants and agreements of Target and Acquiror
contained in this Agreement or in any instrument delivered pursuant to this
Agreement shall survive the Merger and continue until the first anniversary of
the Closing Date (the "EXPIRATION DATE").

        7.2   ESCROW PROVISIONS.

                (a) ESTABLISHMENT OF THE ESCROW FUND. As soon as practicable
        after the Effective Time, the Escrow Amount will be deposited with the
        Depositary Agent (plus a proportionate share of any additional shares of
        Acquiror Common Stock as may be issued upon any stock splits, stock
        dividends or recapitalizations effected by Acquiror following the
        Effective Time), such deposit to constitute the "Escrow Fund" to be
        governed by the terms set forth herein. Notwithstanding the references
        in this Agreement to the "escrow" and the Escrow Fund, the parties
        acknowledge and agree that the Depositary Agent is acting as a
        depository and not as an escrow agent pursuant to this Article 7. The
        shares of Acquiror Common Stock that make up the Escrow Fund shall be
        deducted from the shares otherwise allocable to the Target shareholders
        on a pro rata basis (based on the number of shares of Target Capital
        Stock held by each Target shareholder) or as otherwise provided in
        writing to Acquiror by Target prior to the Closing.

                (b) RECOURSE TO THE ESCROW FUND. The Escrow Fund shall be
        available to compensate Acquiror and its officers, directors, employees,
        agents, Affiliates and Associates for any and all Losses (whether or not
        involving a Third Party Claim), incurred or sustained by Acquiror, its
        officers, directors, employees, agents, Affiliates or Associates,
        directly or indirectly, as a result of (i) any inaccuracy or breach of
        any representation, warranty, covenant or agreement of Target contained
        herein or in the Ancillary Documents or in any instrument delivered
        pursuant to this Agreement; (ii) any amount to which Acquiror is
        entitled pursuant to Section 5.5; and (iii) any Losses incurred by
        Target or the Surviving Corporation over $200,000 to settle or otherwise
        resolve Target's litigation described in Section 2.12 of the Target
        Disclosure Schedules. Notwithstanding the foregoing, Acquiror may not
        make any claims against the Escrow Fund pursuant to clause (i) of the
        preceding sentence with respect to breaches of Target's representations
        and warranties unless the aggregate Losses incurred or sustained in
        respect of all such breaches exceed $250,000 (at which time claims may
        be made for all Losses incurred or sustained). The shareholders of
        Target shall not have any liability under this Agreement in


                                    -56-
<PAGE>

        excess of the Escrow Fund, except in the event of fraud or
        intentional misrepresentation by Target with respect to any of its
        representations, warranties, agreements or covenants contained in
        this Agreement, the Ancillary Agreements or in any other instrument
        or document required to be delivered pursuant to this Agreement in
        connection herewith. In the event of fraud or intentional
        misrepresentation, Acquiror shall have all remedies available at law
        or in equity (including for tort); PROVIDED, HOWEVER, that Acquiror
        shall not proceed against any shareholder of Target to recover any
        Losses until the Escrow Fund shall have been exhausted; and PROVIDED
        FURTHER, that in no event shall any shareholder of Target have any
        liability in excess of the Merger Consideration received by such
        shareholder (with any shares of Acquiror Common Stock being valued at
        the Closing Price). Notwithstanding the foregoing, nothing in this
        Agreement shall limit (i) Acquiror's rights to specific performance
        or injunctive relief with respect to any breach by Target of any of
        Target's covenants or agreements contained herein or in any other
        instrument or document delivered or required to be delivered pursuant
        to this Agreement or (ii) any liability of any holder of Target
        Capital Stock, Target Options or Target Warrants for any breach of
        any agreement executed by such Person in connection with the
        consummation of the transactions contemplated hereby.

                (c) ESCROW PERIOD; DISTRIBUTION OF ESCROW FUND. 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., Central Time, on the Expiration Date (the period of time from
        the Effective Time through and including the Expiration Date is referred
        to herein as the "ESCROW PERIOD"). If there are no unsatisfied claims
        pending against the Escrow Fund on the date which is 180 days after the
        Effective Time, then, as soon as practicable after such date, a number
        of shares of Acquiror Common Stock equal to one-half of the Escrow
        Amount less the number of shares of Acquiror Common Stock theretofore
        paid out of the Escrow Fund in satisfaction of Losses, shall be
        distributed to the former holders of Target Capital Stock in accordance
        with this Section 7.2(c). On the Expiration Date the shares of Acquiror
        Common Stock remaining in the Escrow Fund shall be distributed as set
        forth in this Section 7.2(c); PROVIDED, HOWEVER, that if there are then
        pending any claims against the Escrow Fund any unsatisfied claims under
        this Section 7.2 concerning facts and circumstances existing prior to
        the termination of such Escrow Period which claims are specified in any
        Officer's Certificate delivered to the Depositary Agent prior to
        termination of such Escrow Period, such number of shares of Acquiror
        Common Stock that is necessary in the reasonable judgment of Acquiror,
        subject to the objection of the Shareholder Agent and the subsequent
        arbitration of the matter in the manner as provided in Section 7.2(g)
        hereof, to satisfy such claims shall be retained in the Escrow Fund
        until such time as all such claims shall have been satisfied. As soon as
        all such claims have been resolved, the Depositary Agent shall deliver
        to the former holders of Target Capital Stock any shares of Acquiror
        Common Stock remaining after the resolution of such claims. Deliveries
        of shares of Acquiror Common Stock from the Escrow Fund to the former
        holders of Target Capital Stock pursuant to this Section 7.2(c) shall be
        made ratably in proportion to their respective contributions to the
        Escrow Fund. Each


                                    -57-
<PAGE>

        shareholder of Target who would otherwise be entitled to a fraction
        of a share of Acquiror Common Stock upon any distribution pursuant to
        this Section 7.2(c) shall be entitled to receive from Acquiror in
        lieu of such fractional share an amount of cash (rounded to the
        nearest whole cent) equal to the product of (a) such fraction,
        multiplied by (b) the Closing Price.

                (d) PROTECTION OF ESCROW FUND.

                        (i) The Depositary 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 not as the property of Acquiror
and shall hold and dispose of the Escrow Fund only in accordance with the terms
hereof.

                        (ii) Any cash, property or securities (including Equity
Equivalents) issued or distributed by Acquiror ("DISTRIBUTIONS") in respect of
Acquiror Common Stock shall be paid or made to the former holders of Target
Capital Stock ratably in proportion to their respective contributions to the
Escrow Fund, whether or not such shares of Acquiror Common Stock have been
released from the Escrow Fund; PROVIDED, that any Distribution payable ratably
to all holders of Acquiror Common Stock in the form of additional shares of
Acquiror Common Stock, or entitling the holder thereof to receive, directly or
indirectly, additional shares of Acquiror Common Stock, and any securities
issued in exchange for Acquiror Common Stock, shall remain part of the Escrow
Fund and shall not be paid to the former holders of Target Capital Stock to the
extent such Distributions are paid in respect of shares of Acquiror Common Stock
that have not been released from the Escrow Fund shall be added to the Escrow
Fund.

                        (iii) Each stockholder shall have voting rights with
respect to the shares of Acquiror Common Stock contributed to the Escrow Fund by
such stockholder (and on any voting securities added to the Escrow Fund in
respect of such shares of Acquiror Common Stock).

                (e) CLAIMS UPON ESCROW FUND.

                        (i) Upon receipt by the Depositary Agent at any time on
or before the last day of the Escrow Period of a certificate signed by any
officer of Acquiror (an "OFFICER'S CERTIFICATE"): (A) stating that Acquiror has
paid or properly accrued or reasonably anticipates that it will have to pay or
accrue Losses, directly or indirectly, for which Acquiror is entitled to
indemnification pursuant to Section 7.2(b), (B) specifying in reasonable detail
the individual items of Losses included in the amount so stated, and the date
each such item was paid or properly accrued, or an estimate of the amount (and
the basis therefor) for any anticipated Losses, and (C) the nature of the Losses
and the clause in Section 7.2(b) under which indemnification for each such Loss
is available, the Depositary Agent shall, subject to the provisions of
Section 7.2(f) hereof, deliver to Acquiror out of the Escrow Fund, as promptly
as practicable, shares of Acquiror Common Stock held in the Escrow Fund in an
amount equal to such Losses. Where the basis for a claim upon the Escrow Fund by
Acquiror is that Acquiror reasonably anticipates that it will pay or accrue a
Loss, no payment will be made from the Escrow Fund for such Loss unless and
until such Loss is actually paid or accrued.


                                    -58-
<PAGE>

                        (ii) For the purposes of determining the number of
shares of Acquiror Common Stock to be delivered to Acquiror out of the Escrow
Fund pursuant to Section 7.2(e)(i), the shares of Acquiror Common Stock shall be
valued at the Closing Price.

                (f) OBJECTIONS TO CLAIMS. At the time of delivery of any
        Officer's Certificate to the Depositary Agent, a duplicate copy of such
        certificate shall be delivered to the Shareholder Agent and for a period
        of 30 days after such delivery, the Depositary Agent shall make no
        delivery to Acquiror of any Escrow Amounts pursuant to Section 7.2(e)
        hereof unless the Depositary Agent shall have received written
        authorization from the Shareholder Agent to make such delivery. After
        the expiration of such 30 day period, the Depositary Agent shall make
        delivery of shares of Acquiror Common Stock from the Escrow Fund in
        accordance with Section 7.2(e) hereof, provided that no such payment or
        delivery may be made if the Shareholder Agent shall object in a written
        statement to the claim made in the Officer's Certificate, and such
        statement shall have been delivered to the Depositary Agent prior to the
        expiration of such 30 day period.

                (g) RESOLUTION OF CONFLICTS; ARBITRATION.

                        (i) In case the Shareholder Agent shall object in
writing to any claim or claims made in any Officer's Certificate, the
Shareholder Agent and Acquiror shall attempt in good faith to agree upon the
rights of the respective parties with respect to each of such claims. If the
Shareholder Agent 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 Depositary Agent. The Depositary Agent shall be entitled to rely on any such
memorandum and distribute shares of Acquiror Common Stock from the Escrow Fund
in accordance with the terms thereof. The Depositary Agent shall be entitled to
rely on any such instructions and distribute shares of Acquiror Common Stock
from the Escrow Fund in accordance with the terms thereof.

                        (ii) If no such agreement can be reached after good
faith negotiation, either Acquiror or the Shareholder Agent may demand
arbitration of the dispute unless the amount of the damage or loss is at issue
in a pending Action or Proceeding involving a Third Party Claim, in which event
arbitration shall not be commenced until such amount is ascertained or both
parties agree to arbitration; and in either event the matter shall be settled by
arbitration conducted by three arbitrators, one selected by Acquiror and one
selected by the Shareholder Agent, and the two arbitrators selected by Acquiror
and the Shareholder Agent shall select a third arbitrator. The arbitrators shall
set a limited time period and establish procedures designed to reduce the cost
and time for discovery of information relating to any dispute while allowing the
parties an opportunity, adequate as determined in the sole judgment of the
arbitrators, to discover relevant information from the opposing parties about
the subject matter of the dispute. The arbitrators shall rule upon motions to
compel, limit or allow discovery as they shall deem appropriate given the nature
and extent of the disputed claim. The arbitrators shall also have the authority
to impose sanctions, including attorneys' fees and other costs incurred by the
parties, to the same extent as a court of law or equity, should the arbitrators
determine that discovery was sought without substantial justification or that
discovery was refused or objected to by a party without substantial
justification. The decision of a majority of the three arbitrators as to the


                                    -59-
<PAGE>

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 7.2(f) hereof, the Depositary Agent shall be entitled to act in
accordance with such decision and make or withhold payments out of the Escrow
Fund in accordance therewith. Such decision shall be written and shall be
supported by written findings of fact and conclusions regarding the dispute
which shall set forth the award, judgment, decree or order awarded by the
arbitrators.

                        (iii) Judgment upon any award rendered by the
arbitrators may be entered in any court having competent jurisdiction. Any such
arbitration shall be held in the City of Austin and County of Travis, Texas,
under the commercial rules of arbitration then in effect of the American
Arbitration Association. Each party shall bear is own expenses (including
attorneys' fees and expenses) incurred in connection with any such arbitration,
and the fees and expenses of each arbitrator and the administrative fee of the
American Arbitration Association shall be allocated by the arbitrators (or if
not so allocated, shall be borne equally by Acquiror, on the one hand, and the
former holders of Target Capital Stock, on the other hand).

                (h) SHAREHOLDER AGENT; POWER OF ATTORNEY.

                        (i) In the event that the Merger is approved by the
shareholders of Target, effective upon such vote, and without further act of any
shareholder, Charles Welch shall be appointed as agent and attorney-in-fact (the
"SHAREHOLDER AGENT") for each Shareholder of Target (except such shareholders,
if any, as shall have perfected their appraisal or dissenters' rights under the
California Code), for and on behalf of shareholders of Target, to give and
receive notices and communications, to authorize delivery to Acquiror of shares
of Acquiror Common Stock 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 Shareholder Agent for
the accomplishment of the foregoing. Such agency may be changed by the
shareholders of Target from time to time upon not less than 30 days prior
written notice to Acquiror; PROVIDED, HOWEVER, that the Shareholder Agent may
not be removed unless holders of a two-thirds interest in the Escrow Fund agree
to such removal and to the identity of the substituted Shareholder agent. Any
vacancy in the position of Shareholder Agent may be filled by approval of the
holders of a majority in interest of the Escrow Fund. No bond shall be required
of the Shareholder Agent, and the Shareholder Agent shall not receive
compensation for his services. Notices or communications to or from the
Shareholder Agent shall constitute notice to or from each of the shareholders of
Target.

                        (ii) The Shareholder Agent shall not incur any liability
with respect to any action taken or suffered by him or omitted hereunder as
Shareholder Agent while acting in good faith and any act done or suffered or
omitted hereunder pursuant to the advice of counsel shall be conclusive evidence
of such good faith. The Shareholder Agent may, in all questions arising
hereunder, rely on the advice of counsel and for anything done, omitted or
suffered in good faith by the Shareholder Agent based on such advice, the
Shareholder Agent shall not be liable to anyone. The Shareholder Agent
undertakes to


                                    -60-
<PAGE>

perform such duties and only such duties as are specifically set forth in
this Agreement and no implied covenants or obligations shall be read into
this Agreement or the Escrow Agreement against the Shareholder Agent

                        (iii) The Shareholder Agent shall have reasonable access
to information about Target and the reasonable assistance of Target's officers
and employees for purposes of performing its duties and exercising its rights
hereunder, provided that the Shareholder Agent shall treat confidentially and
not disclose any nonpublic information from or about Target to anyone (except on
a need to know basis to individuals who agree in writing to treat such
information confidentially).

                (i) ACTIONS OF THE SHAREHOLDER AGENT. A decision, act, consent
        or instruction of the Shareholder Agent shall constitute a decision of
        all the shareholders for whom a portion of the Escrow Amount otherwise
        issuable to them are deposited in the Escrow Fund and shall be final,
        binding and conclusive upon each of such shareholders, and the
        Depositary Agent and Acquiror may rely upon any such decision, act,
        consent or instruction of the Shareholder Agent as being the decision,
        act, consent or instruction of every such shareholder of Target. The
        Depositary 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 Shareholder Agent.

                (j) THIRD-PARTY CLAIMS. In the event Acquiror becomes aware of a
        third-party claim (a "THIRD PARTY CLAIM") which Acquiror reasonably
        expects may result in a demand against the Escrow Fund, Acquiror shall
        notify the Shareholder Agent of such claim, and the Shareholder Agent,
        as representative for the shareholders of Target, 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 Third Party
        Claim; PROVIDED, HOWEVER, that if Acquiror settles any Third Party Claim
        without the Shareholder Agent's consent (which consent shall not be
        unreasonably withheld or delayed), Acquiror may not make a claim against
        the Escrow Fund with respect to the amount of Losses incurred by
        Acquiror in such settlement. In the event that the Shareholder Agent has
        consented to any such settlement, the Shareholder Agent shall have no
        power or authority to object under any provision of this Article 7 to
        the amount of any claim by Acquiror against the Escrow Fund with respect
        to the amount of Losses incurred by Acquiror in such settlement.

                (k) INDEMNIFICATION FOR SHAREHOLDER AGENT. The shareholders of
        Target shall, severally and not jointly, on a pro rata basis based on
        their proportionate ownership interests in Target, indemnify, defend and
        hold the Shareholder Agent harmless from and against any loss, damage,
        tax, liability and expense that may be incurred by the Shareholder Agent
        arising out of or in connection with the acceptance or administration of
        the Shareholder Agent's duties, except as caused by the Shareholder
        Agent's gross negligence or willful misconduct, including the legal
        costs and expenses of defending such Shareholder Agent against any claim
        or liability in connection with the performance of the Shareholder
        Agent's duties. The Shareholder Agent shall be entitled, but not limited
        to, such indemnification from the


                                    -61-
<PAGE>

        Escrow prior to any distribution thereof to the shareholders of Target,
        but after any distributions therefrom to Acquiror.

                (l) DEPOSITARY AGENT'S DUTIES.

                        (i) LIMITATION ON DUTIES OF DEPOSITARY AGENT. The
Depositary Agent shall be obligated only for the performance of such duties as
are specifically set forth herein, and as set forth in any additional written
escrow instructions which the Depositary Agent may receive after the date of
this Agreement which are signed by an officer of Acquiror and the Shareholder
Agent, and may rely 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 Depositary Agent shall not be
liable for any act done or omitted hereunder as Depositary 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.

                        (ii) COMPLIANCE WITH ORDERS. The Depositary Agent is
hereby expressly authorized to comply with and obey Orders of any court of law
or Governmental or Regulatory Authority, notwithstanding any notices, warnings
or other communications from any party or any other person to the contrary. In

Agent will not be liable for any damages. Furthermore, the Depositary Agent may
at its option, file an action of interpleader requiring the parties to answer

agree on a successor depositary agent within thirty (30) days after receiving
such notice. If the parties fail to agree upon a successor depositary agent
within such time, the Depositary Agent shall have the right to appoint a

successor depositary 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 depositary
agent as if originally named as Depositary Agent. The Depositary Agent shall be
discharged from any further duties and liability under this Agreement.

                (m) FEES. All fees of the Depositary Agent for performance of

        Depositary Agent renders any service not provided for in this Agreement,
        or if the parties request a substantial modification of its terms, or if
        any controversy arises, or if the Depositary Agent is made a party to,

        fees, and expenses occasioned by such default, delay, controversy or
