       continue to evidence ownership of such shares of capital stock of the
       Surviving Corporation.

        (b)  STOCK OPTIONS; EMPLOYEE STOCK PURCHASE PLAN RIGHTS.  At the

        (c)  ADJUSTMENTS TO THE STOCK PORTION AND THE CASH PORTION.

           (i) Parent, Merger Sub and the Company hereby acknowledge and agree
       that the Cash Portion and the Stock Portion have been determined based
       upon the representations and warranties of the Company set forth in
       SECTION 3.4 hereof. Accordingly, in the event that the representations
       and warranties of the Company set forth in SECTION 3.4 hereof shall be
       determined to be inaccurate in any respect prior to the Effective Time,
       the Cash Portion and

                                      A-8
<PAGE>
       the Stock Portion shall be appropriately adjusted such that (i) the
       aggregate amount of cash payable pursuant to the transactions
       contemplated hereby shall not exceed the aggregate amount of cash that
       otherwise would have been payable pursuant the transactions contemplated
       hereby had such representations and warranties been accurate, and
       (ii) the aggregate number of shares of Parent Common Stock issuable
       pursuant to the transactions shall not exceed the aggregate number of
       shares of Parent Common Stock that otherwise would have been issuable
       pursuant the transactions contemplated hereby had such representations
       and warranties been accurate.

           (ii) The Stock Portion and the Cash Portion shall be adjusted
       appropriately to reflect the effect of any stock split, reverse stock
       split, stock dividend (including any dividend or distribution of
       securities convertible into Company Common Stock), extraordinary cash
       dividends, reorganization, recapitalization, reclassification,
       combination, exchange of shares or other like change with respect to
       Company Common Stock occurring on or after the date hereof and prior to
       the Effective Time. The Stock Portion shall be adjusted appropriately to
       reflect the effect of any stock split, reverse stock split, stock
       dividend (including any dividend or distribution of securities
       convertible into Parent Common Stock), extraordinary cash dividends,
       reorganization, recapitalization, reclassification, combination, exchange
       of shares or other like change with respect to the Parent Common Stock

        (d)  DISSENTING COMPANY SHARES.

           (i) Notwithstanding anything to the contrary set forth in this
       Agreement, all Company Shares that are outstanding immediately prior to
       the Effective Time which are held by stockholders who shall have neither
       voted in favor of the Merger nor consented thereto in writing and who
       shall have properly and validly exercised their dissenters' rights of
       appraisal of such Company Shares in accordance with Section 262 of the
       DGCL (collectively, "DISSENTING COMPANY SHARES") shall not be converted
       into, or represent the right to receive, the Merger Consideration
       pursuant to this SECTION 2.7. Such stockholders shall be entitled to
       receive payment of the appraised value of such Dissenting Company Shares
       in accordance with the provisions of Section 262 of the DGCL, except that
       all Dissenting Company Shares held by stockholders who shall have failed
       to perfect or who effectively shall have withdrawn or lost their rights
       to appraisal of such Dissenting Company Shares under such Section 262 of
       the DGCL shall thereupon be deemed to have been converted into, and to
       have become exchangeable for, as of the Effective Time, the right to
       receive the Merger Consideration, without any interest thereon, upon
       surrender of the certificate or certificates that formerly evidenced such
       Company Shares in the manner provided in SECTION 2.8 hereof.

           (ii) The Company shall give Parent (i) prompt notice of any demands
       for appraisal received by the Company, withdrawals of such demands, and
       any other instruments served pursuant to Delaware Law and received by the
       Company in respect of Dissenting Company Shares, and (ii) the opportunity
       to direct all negotiations and proceedings with respect to demands for
       appraisal under Delaware Law in respect of Dissenting Company Shares. The
       Company shall not, except with the prior written consent of Parent, make
       any payment with respect to any demands for appraisal or offer to settle
       or settle any such demands in respect of Dissenting Company Shares.

    2.8  EXCHANGE OF CERTIFICATES.

        (a)  EXCHANGE AGENT.  Prior to the Effective Time, Parent shall select a
    bank or trust company reasonably acceptable to the Company to act as the
    exchange agent for the Merger (the "EXCHANGE AGENT").

                                      A-9
<PAGE>
        (b)  EXCHANGE FUND.  Promptly after the Effective Time and from time to
    time thereafter (as applicable), Parent shall make available to the Exchange
    Agent, for payment to the holders of shares of Company Common Stock in
    accordance with this ARTICLE II, (i) an amount in cash equal to the product
    obtained by multiplying (x) the Cash Portion, and (y) the aggregate number
    of shares of Company Common Stock outstanding immediately prior to the
    Effective Time (excluding Dissenting Company Shares and shares of Company
    Common Stock held by Parent, Merger Sub, the Company or any other subsidiary
    of Parent immediately prior to the Effective Time), (ii) a number of shares
    of Parent Common Stock equal to the product obtained by multiplying (x) the
    Stock Portion, by (y) the aggregate number of shares of Company Common Stock
    outstanding immediately prior to the Effective Time (excluding Dissenting
    Company Shares and shares of Company Common Stock held by Parent, Merger
    Sub, the Company or any other subsidiary of Parent immediately prior to the
    Effective Time), (iii) the cash amount payable in lieu of fractional shares
    pursuant to SECTION 2.8(g) hereof, and (iv) any dividends and other
    distributions payable pursuant to SECTION 2.11 hereof in respect of shares
    of Parent Common Stock the certificates for which have not yet been issued
    pursuant to this SECTION 2.8 (such cash, shares of Parent Common Stock, cash
    in lieu of fractional shares and dividends and other distributions being
    referred to herein as the "EXCHANGE FUND").

        (c)  PAYMENT PROCEDURES.  Promptly after the Effective Time (but in no
    event more than ten (10) business days thereafter), Parent shall cause the
    Exchange Agent to mail to each holder of record (as of the Effective Time)
    of a certificate or certificates (each, a "CERTIFICATE" and collectively,
    the "CERTIFICATES") which immediately prior to the Effective Time
    represented outstanding shares of Company Common Stock (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
    (ii) instructions for use in effecting the surrender of the Certificates in
    exchange for the Merger Consideration payable in respect of such
    Certificates and any dividends and other distributions to which the holder
    of such Certificates is entitled pursuant to SECTION 2.11 hereof. Upon
    surrender of Certificates for cancellation to the Exchange Agent or to such
    other agent or agents reasonably acceptable to the Company as may be
    appointed by Parent, together with such letter of transmittal, duly
    completed and validly executed in accordance with the instructions thereto,
    and such other documents as may be required pursuant to such instructions,
    the holder of each such Certificate shall be entitled to receive in exchange
    therefor the Merger Consideration payable in respect of the Company Shares
    represented by such Certificate and any dividends and other distributions to
    which the holder of such Certificates is entitled pursuant to SECTION 2.11
    hereof, and the Certificate so surrendered shall forthwith be cancelled. The
    Exchange Agent shall accept such Certificates upon compliance with such
    reasonable terms and conditions as the Exchange Agent may impose to effect
    an orderly exchange thereof in accordance with normal exchange practices. No
    interest shall be paid or accrued for the benefit of holders of the
    Certificates on the cash payable upon the surrender of such Certificates
    pursuant to this SECTION 2.8. Until so surrendered, outstanding Certificates
    shall be deemed from and after the Effective Time to evidence only the right
    to receive the Merger Consideration payable in respect of the Company Shares
    formerly represented thereby pursuant to the terms of this ARTICLE II and
    any dividends and other distributions to which the holder of such
    Certificates is entitled pursuant to SECTION 2.11 hereof.

        (d)  TRANSFERS OF OWNERSHIP.  In the event of a transfer of ownership of
    Company Shares that is not registered in the stock transfer books of the
    Company, the Merger Consideration and any dividends and other distributions
    to which the holder of such Certificates is entitled pursuant to
    SECTION 2.11 hereof may be paid in exchange therefor to a person other than
    the person in whose name the Certificate so surrendered is registered if
    such Certificate shall be properly endorsed or otherwise be in proper form
    for transfer and the person requesting such payment shall pay any transfer
    or other taxes required by reason of the payment of Merger Consideration to
    a person

                                      A-10
<PAGE>
    other than the registered holder of such Certificate or establish to the
    satisfaction of Parent that such tax has been paid or is not applicable.

        (e)  REQUIRED WITHHOLDING.  Each of the Exchange Agent, Parent and the
    Surviving Corporation shall be entitled to deduct and withhold from any
    consideration payable or otherwise deliverable pursuant to this Agreement to
    any holder or former holder of Company Common Stock, or to any holder of a
    Company Stock Option, such amounts as may be required to be deducted or
    withheld therefrom under United States federal or state, local or foreign
    law. To the extent such amounts are so deducted or withheld, such amounts
    shall be treated for all purposes under this Agreement as having been paid
    to the person to whom such amounts would otherwise have been paid.

        (f)  NO LIABILITY.  Notwithstanding anything to the contrary set forth
    in this Agreement, none of the Exchange Agent, Parent, the Surviving
    Corporation or any party hereto shall be liable to a holder of shares of
    Parent Common Stock or Company Common Stock for any amount properly paid to
    a public official pursuant to any applicable abandoned property, escheat or
    similar law.

        (g)  NO FRACTIONAL SHARES.  No fraction of a share of Parent Common
    Stock will be issued in connection with the payment of the Stock Portion of
    the Merger Consideration, but in lieu thereof each holder of a Certificate
    who would otherwise be entitled to receive a fraction of a share of Parent
    Common Stock (after aggregating all fractional shares of Parent Common Stock
    that otherwise would be received by such holder) in the Merger shall receive
    from Parent an amount of cash (rounded to the nearest whole cent), without
    interest, equal to the product obtained by multiplying such fraction by the
    closing price of one (1) share of Parent Common Stock on the date on which
    the Effective Time occurs, as reported on the Nasdaq.

        (h)  DISTRIBUTION OF EXCHANGE FUND TO PARENT.  Any portion of the
    Exchange Fund which remains undistributed to the holders of the Certificates
    on the date that is six (6) months after the Effective Time shall be
    delivered to Parent upon demand, and any holders of Company Shares prior to
    the Merger who have not theretofore surrendered their Certificates
    evidencing such Company Shares for exchange pursuant to this SECTION 2.8
    shall thereafter look for payment of the Merger Consideration payable in
    respect of the Company Shares evidenced by such Certificates solely to
    Parent, as general creditors thereof, for any claim to the applicable Merger
    Consideration to which such holders may be entitled pursuant to this
    ARTICLE II.

    2.9  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  From and after
the Effective Time, all shares of Company Common Stock shall no longer be
outstanding and shall automatically be cancelled, retired and cease to exist and
each holder of a Certificate representing any such Company Shares shall cease to
have any rights with respect thereto, except the right to receive the Merger
Consideration payable therefor upon the surrender thereof in accordance with
SECTION 2.8 hereof. The Merger Consideration issued in accordance with the terms
hereof shall be deemed to have been issued in full satisfaction of all rights
pertaining to such Company Shares. There shall be no further registration of
transfers on the records of the Surviving Corporation of shares of Company
Common Stock which 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 II.

    2.10  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, the Merger
Consideration pursuant to SECTION 2.7 hereof and any dividends and other
distributions to which the holder of such Certificates is entitled pursuant to
SECTION 2.11 hereof; provided, however, that Parent may, in its discretion and
as a condition precedent to the issuance of such Merger Consideration and any
dividends and other distributions to which the holder of such Certificates is
entitled pursuant to

                                      A-11
<PAGE>
SECTION 2.11 hereof, require the owners of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

    2.11  DIVIDENDS AND OTHER DISTRIBUTIONS.  No dividends or other
distributions declared or made after the date of this Agreement with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holders of any unsurrendered Certificates with respect to the shares of
Parent Common Stock represented thereby until the holders of record of such
Certificates shall surrender such Certificates. Subject to applicable law,
promptly following surrender of any such Certificates, the Exchange Agent shall
deliver to the record holders thereof, without interest, the amount of any such
dividends or other distributions with a record date after the Effective Time
payable with respect to such whole shares of Parent Common Stock.

    2.12  MERGER STRUCTURE.  At the election of Parent, the Merger may be
restructured such that, at the Effective Time and upon the terms and subject to
the conditions set forth in this Agreement and the applicable provisions of
Delaware Law, either (i) Merger Sub shall be merged with and into the Company,
the separate corporate existence of Merger Sub shall cease and the Company shall
continue as the surviving corporation of the Merger, or (ii) the Company shall
be merged with and into Parent, the separate corporate existence of the Company
shall cease and Parent shall continue as the surviving corporation of the
Merger; provided, however, that the Merger shall not be restructured pursuant to
this SECTION 2.12 if any such restructuring would cause the condition set forth
in SECTION 7.1(f) hereof to fail to be satisfied. In the event that the Merger
is restructured pursuant to this SECTION 2.12, all references in this
ARTICLE II and elsewhere in this Agreement to the Surviving Corporation shall be
deemed to be references to the Company as the surviving corporation of the
Merger in the case of clause (i) above, or Parent as the surviving corporation
of the Merger in the case of clause (ii) above. Notwithstanding any
restructuring of the Merger pursuant to this SECTION 2.12, the terms and
conditions of this Agreement shall remain in full force and effect, subject to
any changes or revisions that are or may be necessary or appropriate as a result
of such restructuring of the Merger.

    2.13  TAX AND ACCOUNTING CONSEQUENCES.

        (a)  TAX.  It is intended by the parties hereto that the Merger will
    constitute a "reorganization" within the meaning of Section 368(a) of the
    Code, and the parties hereto adopt this Agreement as a "plan of
    reorganization" within the meaning of Section 1.368-2(g) and
    Section 1.368-3(a) of the United States Income Tax Regulations. No party
    hereto shall take any action that is inconsistent with such treatment.

        (b)  ACCOUNTING.  It is intended by the parties that the Merger will be
    accounted for as a purchase.

    2.14  TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes or intent of this Agreement and to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
powers and franchises of the Company and Merger Sub, the officers and directors
of the Company and Merger Sub will take all such lawful and necessary action.

the Company. Each of the Company and its subsidiaries is qualified to do
business as a foreign corporation and is in good standing under the laws of each
jurisdiction where the nature of its business requires such qualification or to

    issuance or outstanding. Except as set forth in SECTION 3.4(b) hereof, there
    are no subscriptions, options, warrants, equity securities, partnership
    interests or similar ownership interests, calls, rights (including

    bound obligating the Company or any of its subsidiaries to issue, deliver or
    sell, or cause to be issued, delivered or sold, or repurchase, redeem or
    otherwise acquire, or cause the repurchase, redemption or acquisition of,

    3.5  AUTHORITY.  The Company has all necessary corporate power and authority
to execute and deliver this Agreement, the Company Voting Agreements and the
Company Affiliate Agreements, to perform its obligations hereunder and
thereunder and, subject to the adoption and approval of this Agreement and the
Merger by the stockholders of the Company (if required under Delaware Law), to
consummate the transactions contemplated hereby and thereby. The execution and
delivery of this Agreement, the Company Voting Agreements and the Company
Affiliate Agreements by the Company, the performance by the Company of its
obligations hereunder and thereunder, and the consummation by the Company of the
transactions contemplated hereby and thereby, have been duly and validly
authorized by all necessary corporate action on the part of the Company, and no
other corporate proceedings on the part of the Company (other than the adoption

    have been timely made in accordance with DOL regulation Section 2510.3-102.
    There are no actions, suits or, to the knowledge of the Company, claims
    pending or threatened (other than routine claims for benefits) against any

    without material liability to Parent, the Company or any of the Company
    Affiliates (other than benefits accrued to date and ordinary administration
    expenses). There are no audits, inquiries or proceedings pending or, to the
    knowledge of the Company, threatened by the IRS or DOL with respect to any
    Company Employee Plan. Neither the Company nor any Company Affiliate is

    or reflects or represents any liability to provide retiree health insurance
    coverage to any person for any reason, except as may be required by COBRA or
    other applicable statute.

        (h)  HEALTH CARE COMPLIANCE.  Neither the Company nor any Company

       consummation by the Company of the transactions contemplated hereby will
       not (either alone or upon the occurrence of any additional or subsequent
       events), constitute an event under any Company Employee Plan, Company
       Employment Agreement, trust or loan that will or may result in any
       payment (whether of severance pay or otherwise), acceleration,
       forgiveness of indebtedness, vesting, distribution, increase in benefits
       or obligation to fund benefits with respect to any Company Employee.

           (ii) No payment or benefit which will or may be made by the Company

       Section 280G(b)(2) of the Code.

        (j)  EMPLOYMENT MATTERS.  To the knowledge of the Company, the Company:
    (i) is in material compliance in all respects with all applicable foreign,

    disputes or grievances pending, or, to the knowledge of the Company,
    threatened or reasonably anticipated relating to any labor, safety or
    discrimination matters involving any Company Employee, including, without
    limitation, charges of unfair labor practices or discrimination complaints,
    which, if adversely determined, would, individually or in the aggregate,
    result in any material liability to the Company. Neither the Company nor any
    of its subsidiaries has engaged in any unfair labor practices within the
    meaning of the National Labor Relations Act. The Company is not presently,
    nor has it been in the past, a party to, or bound by, any collective

    taxation by such jurisdiction) has been proposed in writing formally or
    informally by any Tax authority to the Company or any of its subsidiaries.

    3.17  INTELLECTUAL PROPERTY MATTERS.

        (a) No Company Intellectual Property or product owned by the Company or
    service offering of the Company or any of its subsidiaries (a "COMPANY
    PRODUCT") is subject to any proceeding or outstanding decree, order,
    judgment, or stipulation restricting in any material manner, or any Contract
    restricting in any material manner the use, transfer, or licensing thereof
    by the Company or any of its subsidiaries, or which may materially affect
    the validity, use or enforceability of such Company Intellectual Property or
    Company Product.

        (b) Each material item of Company Registered Intellectual Property is
    valid and subsisting, all necessary registration, maintenance and renewal
    fees currently due in connection with such Company Registered Intellectual
    Property have been made and all necessary documents, recordations and
    certificates in connection with such Company Registered Intellectual
    Property have been filed with the relevant patent, copyright, trademark or
    other authorities in the United States or foreign jurisdictions, as the case
    may be, for the purposes of prosecuting, perfecting and maintaining such
    Company Registered Intellectual Property. The Company has not claimed any
    status in the application for or registration of any Registered Intellectual
    Property Rights, including "small business status," that would not be
    applicable to Purchaser.

        (c) In each case in which the Company has acquired any Intellectual
    Property from any person, the Company has obtained a valid and enforceable
    assignment sufficient to irrevocably transfer all rights in and to such
    Intellectual Property (including the right to seek past and future damages
    with respect thereto) to the Company sufficient for the Company to conduct
    its business as currently conducted or proposed to be conducted. To the
    maximum extent provided for by, and in accordance with, applicable laws and
    regulations, the Company has recorded each such assignment of a Registered
    Intellectual Property Right assigned to the Company with the relevant
    Governmental Entity.

        (d) All Company Intellectual Property will be fully transferable,
    alienable or licensable by Surviving Corporation and/or Parent without
    restriction and without payment of any kind to any person except for
    ordinary course restrictions or payments that would apply to the Company had
    the transactions contemplated by this Agreement not occurred.

        (e) The Company owns, and has good and exclusive title to, each item of
    Company Intellectual Property owned by it free and clear of any lien or
    encumbrance (excluding non-exclusive licenses and related restrictions
    granted in the ordinary course). Without limiting the foregoing: (i) the
    Company is the exclusive owner of all trademarks and trade names purported
    to be owned by the Company that are used in connection with the operation or
    conduct of the business of the Company and its subsidiaries, including the
    sale, distribution or provision of any Company Products by the Company or
    its subsidiaries; (ii) the Company owns exclusively, and has good title to,
    all copyrighted works that are Company Products or services or which the
    Company or any of its subsidiaries otherwise purports to own; and (iii) to
    the extent that any Patents would be infringed by any Company Products, to
    the knowledge of the Company, the Company is the exclusive owner of such
    Patents, or has secured appropriate rights through license or other
    agreement.

        (f) Within the past year, the Company has not (i) transferred ownership
    of, or granted any exclusive license of or exclusive right to use, or
    authorized the retention of any exclusive rights to use or joint ownership
    of, material Company Intellectual Property that was or is currently
    purported to be owned by the Company, to any other person, or
    (ii) permitted the Company's rights in such material Company Intellectual
    Property to lapse or enter the public domain.

        (g) All Company Intellectual Property used in or necessary to the
    conduct of the Company's business as presently conducted or reasonably
    contemplated to be conducted by the Company was

                                      A-23
<PAGE>
    written and created solely by either (i) employees of the Company acting
    within the scope of their employment or (ii) by third parties who have
    exclusively licensed to the Company or validly and irrevocably assigned all
    of their rights, including all Intellectual Property rights therein, to the
    Company, and no such third party owns or has any rights to any of the
    Company Intellectual Property purported to be owned by the Company.

        (h) The Company Intellectual Property and other Intellectual Property
    licensed by the Company constitutes all the Intellectual Property used in
    and/or necessary to the conduct of the business of the Company as it
    currently is conducted, and as it is reasonably planned or contemplated to
    be conducted by the Company, including, without limitation, the design,
    development, manufacture, use, import, sale and licensing of Company
    Products.

        (i) No person who has licensed any Intellectual Property to the Company
    has ownership rights or license rights granted by the Company to
    improvements made by or for the Company in such Intellectual Property.

        (j) The Company has the right to use, pursuant to valid licenses, all
    operating software (including software required to provide services offered
    by the Company), software development tools, library functions, compilers
    and all other third-party software that are used in the operation of the
    Company or that are required to create, modify, compile, operate or support
    any software that is Company Intellectual Property or is incorporated into
    any Company Product. Without limiting the foregoing, no open source or
    public library software, including any version of any software licensed
    pursuant to any GNU public license, was used in the development or
    modification of any software that is Company Intellectual Property.

        (k) Any agreements between the Company and other persons for the
    development or manufacture of a Company Product will permit the Company to
    continue the development or manufacture of any such product notwithstanding
    any termination or expiration of such agreement(s), without the payment of
    any additional royalty, fee or other payment to any such other person (other
    than accrued fees or payments).

        (l) The Company has no knowledge of any information, materials, facts,
    or circumstances, including any information or fact that would constitute
    prior art, that would render any of the Company Registered Intellectual
    Property invalid or unenforceable, or would materially affect any pending
    application for any Company Registered Intellectual Property and the Company
    has not knowingly misrepresented, or knowingly failed to disclose, any facts
    or circumstances in any application for any Company Registered Intellectual
    Property that would constitute fraud or a misrepresentation with respect to
    such application or that would otherwise affect the validity or
    enforceability of any Company Registered Intellectual Property.

        (m) To the extent that any technology, software or Intellectual Property
    has been developed or created independently or jointly by another person or
    employee for the Company or any of its subsidiaries or is incorporated into
    any of the Company Products, the Company has a written or electronic
    agreement with such third party or employee with respect thereto and the
    Company thereby either (i) has obtained ownership of, and is the exclusive
    owner of, or (ii) has obtained a license (sufficient for the conduct of its
    business as currently conducted and as proposed to be conducted) to such
    person's Intellectual Property in such work, material or invention.

        (n)  SECTION 3.17(n) of the Company Schedule contains a complete and
    accurate list of all material Contracts to which the Company or any of its
    subsidiaries is a party (i) with respect to Company Intellectual Property
    licensed or transferred to any third party (other than licenses or support
    and maintenance agreements entered into in the ordinary course), or
    (ii) pursuant to which a third party has licensed or transferred any
    material Intellectual Property to the Company.

                                      A-24
<PAGE>
        (o)  SECTION 3.17(o) of the Company Schedule contains a complete and
    accurate list of all material contracts, licenses and agreements between the
    Company and any other person wherein or whereby the Company has agreed to,
    or assumed, any obligation or duty to warrant, indemnify, reimburse, hold
    harmless, guaranty or otherwise assume or incur any obligation or liability
    or provide a right of rescission with respect to the infringement or
    misappropriation by the Company of the Intellectual Property Rights of any
    person other than the Company, other than in the ordinary course of
    business.

        (p) All material Contracts relating to either (i) Company Intellectual
    Property, or (ii) Intellectual Property of another person licensed to the
    Company or any of its subsidiaries, including, without limitation, third
    party licenses to the Company relating to or in any way permitting Company
    Products, services or Company Intellectual Property to interoperate with
    other products, systems or standards, are in full force and effect (other
    than those which have expired by their terms). The execution and delivery of
    this Agreement by the Company have not violated or resulted in, and the
    performance by the Company of its obligations hereunder and the consummation
    by the Company of the transactions contemplated hereby will not violate or
    result in, the breach, modification, cancellation, termination or suspension
    of such Contracts. Each of the Company and its subsidiaries is in material
    compliance with, and has not materially breached any term of any such
    Contracts and, to the knowledge of the Company, all other parties to such
    contracts, licenses and agreements are in compliance with, and have not
    materially breached any term of, such Contracts. Following the Effective
    Time, the Surviving Corporation will be permitted to exercise all of the
    Company's rights under such Contracts to the same extent the Company and its
    subsidiaries would have been able to had the transactions contemplated by
    this Agreement not occurred and without the payment of any additional
    amounts or consideration other than ongoing fees, royalties or payments
    which the Company would otherwise be required to pay. Neither this Agreement
    nor the transactions contemplated by this Agreement will result in, by
    virtue of the terms of any Contract to which the Company or any of its
    subsidiaries is a party or by they are bound, (i) either the granting by
    Parent or Merger Sub to any other person any right to or with respect to any
    Intellectual Property right owned by, or licensed to, either of them (other
    than Intellectual Property acquired pursuant to this Agreement),
    (ii) either Parent's or the Merger Sub's being bound by, or subject to, any
    non-compete or other material restriction on the operation or scope of their
    respective businesses, or (iii) either Parent, Merger Sub or the Company, as
    the case may be, being obligated to pay any royalties or other material
    amounts to any third party in excess of those payable by Parent or the
    Company, respectively, prior to the Effective Time.

        (q) The operation of the business of the Company and its subsidiaries as
    such business currently is conducted or is currently contemplated to be
    conducted has not, does not and, to its knowledge, will not infringe or
    misappropriate, the Intellectual Property of any third party or constitute
    unfair competition or trade practices under the laws of any jurisdiction;
    PROVIDED HOWEVER, that with respect to Patents, the foregoing representation
    is made to the knowledge of the Company.

        (r) Neither the Company nor any of its subsidiaries has received written
    notice from any third party alleging that the operation of the business of
    the Company or any of its subsidiaries or any act, product or service
    (including Company Products, technology or service offerings currently under
    development) of the Company or any of its subsidiaries, infringes or
    misappropriates the Intellectual Property of any third party or constitutes
    unfair competition or trade practices under the laws of any jurisdiction.

        (s) To the knowledge of the Company, no person has or is infringing or
    misappropriating any Company Intellectual Property.

                                      A-25

        (t) The Company and each of its subsidiaries has taken reasonable steps
    to protect the rights of the Company and its subsidiaries in the Company's
    confidential information and trade secrets that it wishes to protect or any
    trade secrets or confidential information of third parties provided to the
    Company or any of its subsidiaries under an obligation of confidentiality,
    and, without limiting the foregoing, each of the Company and its
    subsidiaries has required each employee and contractor to execute a
    proprietary information/confidentiality agreement and all current and former
    employees and contractors of the Company and any of its subsidiaries have
    executed such an agreement, except where the failure to do so is not
    reasonably expected to be material to the Company.

    liability to the Company or any of its subsidiaries, no underground storage

    its employees or others to Hazardous Materials in violation of any law in

    3.20  INSURANCE.  The Company has furnished or made available to Parent a

<PAGE>
subsidiaries is a party, beneficiary or named insured (each a "COMPANY INSURANCE
POLICY" and collectively, the "COMPANY INSURANCE POLICIES"). The Company
believes that the Company Insurance Policies are of the type and in amounts
customarily carried by persons conducting businesses similar to those of the
Company and its subsidiaries. There is no material claim by the Company or any
of its subsidiaries pending under any of the Company Insurance Policies as to
which coverage has been questioned, denied or disputed by the underwriters of
such policies or bonds.

    3.21  OPINION OF FINANCIAL ADVISOR.  The Company Board has been advised by
its financial advisor, Morgan Stanley & Co., Inc., that in such advisor's
opinion, as of the date of this Agreement, the Merger Consideration is fair to
the holders of Company Shares (other than Parent and its affiliates) from a
financial point of view, and the written confirmation of such opinion has been
delivered to Parent.

    3.22  BROKERS.  Except for fees payable to Morgan Stanley & Co., Inc.
pursuant to an engagement letter, dated May 23, 2001, a complete and accurate
copy of which has been furnished to Parent, the Company has not incurred, nor
will it incur, directly or indirectly, any liability for brokerage or finders
fees or agent's commissions or any similar charges in connection with this
Agreement, the Merger or any transaction contemplated hereby.

    3.23  STATE TAKEOVER STATUTES.  The Company Board has approved this
Agreement, the Merger and the other transactions contemplated hereby, and the
Company Voting Agreements and the transactions contemplated thereby, and such
approval is sufficient to render inapplicable to this Agreement, the Merger and
the other transactions contemplated hereby, and to the Company Voting Agreements
and the transactions contemplated thereby, the provisions of Section 203 of the
DGCL to the extent, if any, Section 203 of the DGCL is applicable to this
Agreement, the Merger and the other transactions contemplated hereby, and to the
Company Voting Agreements and the transactions contemplated thereby. No other
state takeover statute or similar statute or regulation applies to or purports
to apply to this Agreement, the Merger or the other transactions contemplated
hereby, or to the Company Voting Agreements and the transactions contemplated

adopt and approve this Agreement and approve the Merger under Delaware Law.

    3.25  REORGANIZATION.  Neither the Company nor any of its subsidiaries has
taken any action that has caused, or would reasonably be expected to cause, the
Merger to fail to qualify a "reorganization" within the meaning of
Section 368(a) of the Code.

    3.26  REGISTRATION STATEMENT; PROXY STATEMENT/PROSPECTUS.  None of the
information supplied or to be supplied by the Company for inclusion or
incorporation by reference in the Registration Statement will, at the time the
Registration Statement is declared or ordered effective under the Securities
Act, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The Proxy Statement/Prospectus will not, as of the Effective Time,
on the date mailed to the Company's stockholders, and at the time of the Company
Stockholder Meeting, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading. The Proxy Statement/Prospectus will comply as to form in
all material respects with the provisions of the Exchange Act and the rules and

standing under the laws of the jurisdiction of its incorporation and has the
requisite corporate power and authority to own, lease and operate its assets and

Approvals necessary to own, lease and operate the properties it purports to own,
operate or lease and to carry on its business as it is currently being
conducted, except as would not, individually or in the aggregate, have a
Material Adverse Effect on Parent. Each of Parent and its subsidiaries at all
times has been, and currently is, in compliance with the terms of the Approvals

aggregate, reasonably be expected to have a Material Adverse Effect on Parent.
Each of Parent and its subsidiaries is qualified to do business as a foreign
corporation and is in good standing under the laws of each jurisdiction where
the nature of its business requires such qualification or to be in good
standing, except where the failure to be so qualified or in good standing would

Company complete and correct copies of its Certificate of Incorporation and
Bylaws as amended to date (together, the "PARENT CHARTER DOCUMENTS"). The Parent
Charter Documents and equivalent organizational documents of each of its
subsidiaries are in full force and effect, Parent is not in violation of any of
the provisions of the Parent Charter Documents, and no subsidiary of Parent is

    of the material terms and conditions of such Acquisition Proposal and of the
    Company's intention to furnish nonpublic information to, or engage or
    participate in discussions or negotiations with, such person, and
    (4) contemporaneously with furnishing any such information to such person,
    the Company furnishes such information to Parent (to the extent such
    information has not been previously furnished by Company to Parent). The
    Company and its subsidiaries shall immediately cease any and all existing
    activities, discussions or negotiations with any persons conducted
    heretofore with respect to any Acquisition Proposal. Without limiting the
    foregoing, it is understood that any violation of the restrictions set forth
    in this SECTION 6.1 by any officer, director or employee of the Company or
    any of its subsidiaries or any investment banker, attorney or other advisor
    or representative of the Company or any of its subsidiaries shall be deemed
    to be a breach of this SECTION 6.1 by Company. The Company shall not be
    entitled to enter into any letter of intent or similar document or any
    Contract (other than a confidentiality agreement as permitted by this
    SECTION 6.1) contemplating or otherwise relating to an Acquisition Proposal
    unless and until this Agreement is terminated by its terms pursuant to
    ARTICLE VIII hereof and the Company has paid all amounts due to Parent
    pursuant to SECTION 8.4 hereof.

    or proposal by Parent) relating to any Acquisition Transaction; (ii) the
    term "ACQUISITION TRANSACTION" shall mean any transaction or series of
    related transactions other than the transactions contemplated by this
    Agreement involving: (A) any acquisition or purchase from the Company by any
    person or "group" (as defined under Section 13d of the Exchange Act) of more
    than a fifteen percent (15%) interest in the total outstanding voting
    securities of the Company or any of its subsidiaries or any tender offer or
    exchange offer that if consummated would result in any person or "group" (as
    defined under Section 13(d) of the Exchange Act) beneficially owning fifteen
    percent (15%) or more of the total outstanding voting securities of the
    Company or any of its subsidiaries or any merger, consolidation, business

    or resulting entity of such transaction; (B) any sale, lease (other than in
    the ordinary course of business), exchange, transfer, license (other than in
    the ordinary course of business), acquisition or disposition of more than

    Company Board shall have reasonably determined in good faith (after
    consultation with a financial advisor of a nationally recognized standing)
    (A) taking into account, among other things, the legal, financial and
    regulatory aspects of such Acquisition Proposal and the person making such
    Acquisition Proposal, that the acquiring party is capable of consummating
    the proposed Acquisition Transaction on the terms proposed (including,
    without limitation, the acquiring person's ability to obtain any necessary
    financing), and (B) that the proposed Acquisition Transaction would, if
    consummated, be more favorable to the Company's stockholders (in their
    capacities as such), from a financial point of view, than the transactions
    contemplated by this Agreement.

        (c) In addition to the obligations of Company set forth in
    SECTION 6.1(a) hereof, the Company shall, as promptly as practicable, advise
    Parent orally and in writing of any request for information which the
    Company reasonably believes could lead to a BONA FIDE Acquisition Proposal
    or of any Acquisition Proposal, or any inquiry with respect to or which the
    Company reasonably believes could lead to any BONA FIDE Acquisition
    Proposal, the material terms and conditions of such request, Acquisition

    Proposal.

    6.2  COMPANY STOCKHOLDER MEETING.  Promptly after the date hereof, the
Company shall take all action necessary under Delaware Law and the Company
Charter Documents to call and hold a meeting of the stockholders of the Company
(the "COMPANY STOCKHOLDER MEETING") to be held as promptly as reasonably
practicable for the purpose of voting upon the adoption and approval of this
Agreement and the approval of the Merger, and the Company shall use all
commercially reasonable efforts to hold the Company Stockholder Meeting as
promptly as practicable after the date upon which the Registration Statement is
declared or ordered effective by the SEC. Notwithstanding anything to the

                                      A-37
<PAGE>
contrary set forth in this Agreement, the Company may adjourn or postpone the
Company Stockholder Meeting to the extent necessary to ensure that any necessary
supplement or amendment to the Proxy Statement/Prospectus is provided to the
Company's stockholders in advance of a vote on this Agreement and the Merger at
the Company Stockholder Meeting or if, as of the time for which the Company
Stockholder Meeting (as set forth in the Proxy Statement/Prospectus), there are
insufficient shares of Company Common Stock represented (either in person or by
proxy) at the Company Stockholder Meeting to constitute a quorum necessary to
conduct business at the Company Stockholder Meeting. Subject to SECTION 6.3(c)
hereof, the Company shall use all commercially reasonable efforts to solicit
from its stockholders proxies in favor of the adoption and approval of this
Agreement and the approval of the Merger, and shall take all other commercially
reasonable action necessary or advisable to secure the Requisite Company
Stockholder Vote at the Company Stockholder Meeting. The Company shall ensure
that the Company Stockholder Meeting is called, noticed, convened, held and
conducted, and that all proxies solicited by the Company in connection with the
Company Stockholder Meeting, are solicited in compliance with Delaware Law, the
Company Charter Documents, the rules of the Nasdaq and all other applicable
Legal Requirements. Unless this Agreement shall be earlier terminated pursuant
to ARTICLE VIII hereof, the Company shall call and hold the Company Stockholder
Meeting for the purpose of voting upon the adoption and approval of this
Agreement and the approval of the Merger whether or not the Company Board at any
time subsequent to the date hereof determines that this Agreement is no longer
advisable or recommends that Company's stockholders reject it. Notwithstanding
anything to the contrary contained in this Agreement, the Company's obligation
to establish a record date for, call, give notice of, convene and hold the
Company Stockholder Meeting pursuant to this SECTION 6.2 shall not be limited to
or otherwise affected by the commencement, disclosure, announcement or
submission to the Company of any Acquisition Proposal.

    6.3  PREPARATION AND FILING OF REGISTRATION STATEMENT AND PROXY
STATEMENT/PROSPECTUS; WITHDRAWAL OF COMPANY BOARD RECOMMENDATION.

        (a) Promptly after the date hereof, Parent and the Company shall prepare
    and the Company shall file with the SEC a proxy statement for use in
    connection with the solicitation of proxies from the Company's stockholders
    in favor of the adoption and approval of this Agreement and the approval of
    the Merger at the Company Stockholder Meeting (the "PROXY
    STATEMENT/PROSPECTUS"), and Parent and the Company shall prepare and Parent
    shall file with the SEC a registration statement on Form S-4 (or any
    successor form thereto) (the "REGISTRATION STATEMENT") for the offer and
    sale of the Parent Common Stock pursuant to the Merger and in which the
    Proxy Statement/ Prospectus will be included as a prospectus. Each of Parent
    and the Company shall 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 Proxy Statement/Prospectus and the
    Registration 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 Proxy Statement/Prospectus and the
    Registration Statement. Each of Parent and the Company shall use all
    commercially reasonable efforts to have the Registration Statement declared
    or ordered effective under the Securities Act as promptly as practicable
    after such filing with the SEC. The Company shall use all commercially
    reasonable efforts to cause the Proxy Statement/Prospectus to be mailed to
    the Company's stockholders as promptly as practicable after the Registration
    Statement is declared or ordered effective under the Securities Act. Parent
    shall also take any action (other than qualifying to do business in any
    jurisdiction in which it is not now so qualified or to file a general
    consent to service of process) required to be taken under any applicable
    state securities laws in connection with the issuance of Parent Common Stock
    in the Merger and the Company shall furnish all information concerning the
    Company and the holders of capital stock of the Company as may be reasonably
    requested in connection with any such action and the preparation, filing and
    distribution of the Proxy Statement/Prospectus. No filing of, or amendment
    or supplement to, or

                                      A-38
<PAGE>
    correspondence to the SEC or its staff with respect to, the Registration
    Statement will be made by Parent, or with respect to the Proxy
    Statement/Prospectus will be made by Company, without providing the other
    party hereto a reasonable opportunity to review and comment thereon. Parent
    will advise the Company, promptly after it receives notice thereof, of the
    time when the Registration Statement has become effective or any supplement
    or amendment has been filed, the issuance of any stop order, the suspension
    of the qualification of the Parent Common Stock issuable in connection with
    the Merger for offering or sale in any jurisdiction, or any request by the
    SEC for amendment of the Registration Statement or comments thereon and
    responses thereto or requests by the SEC for additional information. The
    Company shall advise Parent, promptly after it receives notice thereof, of
    any request by the SEC for the amendment of the Proxy Statement/Prospectus
    or comments thereon and responses thereto or requests by the SEC for
    additional information. If at any time prior to the Effective Time any
    information relating to Parent or the Company, or any of their respective
    affiliates, officers or directors, should be discovered by Parent or the
    Company which should be set forth in an amendment or supplement to either of
    the Registration Statement or the Proxy Statement/Prospectus, so that any of
    such documents would not include any misstatement of a material fact or omit
    to state any material fact necessary to make the statements therein, in
    light of the circumstances under which they were made, not misleading, the
    party which discovers such information shall promptly notify the other party
    or parties hereto, as applicable, and an appropriate amendment or supplement
    to the Registration Statement and/or the Proxy Statement/Prospectus
    describing such information shall be promptly filed with the SEC and, to the
    extent required by applicable law, disseminated to the stockholders of the
    Company. Each of the parties hereto shall cause the Proxy Statement/
    Prospectus to comply as to form and substance to such party in all material
    respects with the applicable requirements of the Exchange Act, the
    Securities Act and the rules of the Nasdaq.

        (b) Subject to the terms of SECTION 6.3(c) hereof, (i) the Company Board
    shall recommend that the Company's stockholders vote in favor of the
    adoption and approval of this Agreement and the approval of the Merger at
    the Company Stockholder Meeting; PROVIDED, HOWEVER, that the Company Board
    shall submit this Agreement to the Company's stockholders whether or not at
    any time subsequent to the date hereof the Company Board determines that it
    can no longer make such recommendation, (ii) the Proxy Statement/Prospectus
    shall include a statement to the effect that the Company Board has
    recommended that the Company's stockholders vote in favor of the adoption
    and approval of this Agreement and the approval of the Merger at the Company
    Stockholder Meeting, and (iii) neither the Company Board nor any committee
    thereof shall withdraw, amend or modify, or propose or resolve to withdraw,
    amend or modify, in a manner adverse to Parent, the recommendation of the
    Company Board that the Company's stockholders vote in favor of the adoption
    and approval of this Agreement and the approval of the Merger at the Company
    Stockholder Meeting.

        (c) Nothing in this Agreement shall prevent the Company Board from
    withholding, withdrawing, amending or modifying its unanimous recommendation
    in favor of the approval and adoption of this Agreement and approval of the
    Merger if (i) a Superior Offer is made to the Company and is not withdrawn,
    (ii) neither the Company nor any of its representatives shall have violated
    any of the terms of SECTION 6.1 hereof, and (iii) the Company Board
    concludes in good faith, after consultation with its outside counsel, that,
    in light of such Superior Offer, the withholding, withdrawal, amendment or
    modification of such recommendation is required in order for the Company
    Board to comply with its fiduciary duties to the Company's stockholders
    under Delaware Law; PROVIDED, HOWEVER, that prior to any commencement
    thereof the Company shall have given Parent at least seventy two (72) hours
    notice thereof. Nothing contained in this SECTION 6.3(c) shall limit the
    Company's obligation to hold and convene the Company Stockholder Meeting
    (regardless of whether the unanimous recommendation of the Company Board
    shall have been withdrawn, amended or modified). Nothing in this
    SECTION 6.3(c) shall prohibit the Company

                                      A-39
<PAGE>
    Board from (i) taking and disclosing to the Company's stockholders a
    position contemplated by Rule 14e-2(a) promulgated under the Exchange Act,
    (ii) complying with the provisions of Rule 14d-9 promulgated under the
    Exchange Act, or (iii) making any disclosure that is required to comply with
    the Company Board's duty of candor (including, without limitation, a change
    of recommendation in favor of the adoption and approval of this Agreement
    and the approval of the Merger by the Company's stockholders) to the
    Company's stockholders under Delaware Law, provided that the Company Board
    concludes in good faith, after consultation with its outside legal counsel,
    that taking any of the actions referred to in the foregoing clauses (i),
    (ii) or (iii) is required in order for the Company Board to comply with its
    fiduciary obligations to the Company's stockholders under Delaware Law.

    6.4  CONFIDENTIALITY.  The parties acknowledge that Company and Parent have
previously executed a Confidentiality Agreement, dated as of June 1, 2001 (the
"CONFIDENTIALITY AGREEMENT"), which will continue in full force and effect in
accordance with its terms.

    6.5  ACCESS TO INFORMATION.  The Company and Parent shall afford each other
and their respective accountants, counsel and other representatives reasonable
access during normal business hours, upon reasonable notice, to their respective
properties, books, records and personnel during the period prior to the
Effective Time to obtain all information concerning their respective businesses,
including the status of product development efforts, properties, results of
operations and personnel, as either Parent or the Company may reasonably
request. No information or knowledge obtained by Parent or the Company in any
investigation pursuant to this SECTION 6.5 will affect or be deemed to modify
any representation or warranty contained herein or the conditions to the
obligations of the parties to consummate the Merger.

    6.6  PUBLIC DISCLOSURE.  Parent and the Company shall consult with each
other, and agree, before issuing any press release or otherwise making any
public statement with respect to this Agreement, the Merger, the other party or
parties hereto, or any Acquisition Proposal, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable law or any listing agreement with a national
securities exchange or the Nasdaq, in which case reasonable efforts to consult
with the other party will be made prior to any such release or public statement.

    6.7  COMMERCIALLY REASONABLE EFFORTS.  Upon the terms and subject to the
conditions set forth in this Agreement, each of Parent, Merger Sub and the
Company shall use its respective commercially reasonable efforts to take, or
cause to be taken, all reasonable actions, and to do, or cause to be done, and
to assist and cooperate with the other party or parties hereto in doing, all
things reasonably necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the other
transactions contemplated hereby, including, without limitation, to accomplish
the following: (i) causing of the conditions precedent set forth in ARTICLE VII
hereto be satisfied, (ii) the obtaining of all necessary actions or nonactions,
waivers, consents, approvals, orders and authorizations from Governmental
Entities and the making of all necessary registrations, declarations and filings
(including registrations, declarations and filings with Governmental Entities,
if any) and the taking of all commercially reasonable steps as may be necessary
to avoid any suit, claim, action, investigation or proceeding by any
Governmental Entity, (iii) the defending of any suits, claims, actions,
investigations or proceedings, whether judicial or administrative, challenging
this Agreement or the consummation of the Merger or any other transactions
contemplated hereby, including, without limitation, seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed; and (iv) the execution or delivery of any additional
instruments reasonably necessary to consummate the Merger or the other
transactions contemplated hereby, and to fully carry out the purposes and intent
of, this Agreement. In connection with and without limiting the foregoing, the
Company and the Company Board shall, if any state takeover statute or similar
statute or regulation is or becomes applicable to this Agreement or any of the

                                      A-40
<PAGE>
transactions contemplated by this Agreement, use all commercially reasonable
efforts to take, or cause to be taken, all reasonable actions to ensure that the
transactions contemplated by this Agreement may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise to
minimize the effect of such statute or regulation on this Agreement and the
transactions contemplated hereby. Notwithstanding anything herein to the
contrary, nothing in this Agreement shall be deemed to require Parent, Merger
Sub or the Company or any subsidiary or affiliate thereof to agree to any
divestiture (including, without limitation, through a licensing arrangement) by
itself or any of its affiliates of shares of capital stock or of any business,
assets or property, or the imposition of any limitation on the ability of any of
them to conduct their business or to own or exercise control of such assets,
properties and stock.

    6.8  NOTIFICATION.  The Company shall give prompt notice to Parent upon
becoming aware that any representation or warranty made by it contained in this
Agreement has become materially untrue or inaccurate, or of any failure of the
Company to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by the Company under
this Agreement; PROVIDED, HOWEVER, that no such notification shall affect the
representations, warranties, covenants or agreements of the Company set forth in
this Agreement or the conditions to the obligations of the Company set forth in
this Agreement. Parent shall give prompt notice to the Company upon becoming
aware that any representation or warranty made by Parent or Merger Sub contained
in this Agreement has become materially untrue or inaccurate, or of any failure

Merger Sub under this Agreement; PROVIDED, HOWEVER, that no such notification
shall affect the representations, warranties, covenants or agreements of Parent
or Merger Sub or the conditions to the obligations of Parent and Merger Sub
under this Agreement.

    6.9  THIRD PARTY CONSENTS.  As soon as practicable following the date
hereof, the Company shall use all commercially reasonable efforts to obtain all
consents, waivers and approvals set forth in SECTION 3.6 of the Company Schedule
that Parent has requested in writing that the Company obtain.

       then vested or exercisable, shall be assumed by Parent. Each Company
       Stock Option so assumed by Parent under this Agreement will continue to
       have, and be subject to, the same terms and conditions of such options
       immediately prior to the Effective Time (including, without limitation,
       any repurchase rights or vesting provisions), except that (i) each
       Company Stock Option will be exercisable (or will become exercisable in
       accordance with its terms) for that number of whole shares of Parent
       Common Stock equal to the product (rounded down to the nearest whole
       number of shares of Parent Common Stock) of the number of shares of
       Company Common Stock that were issuable upon exercise of such Company
       Stock Option immediately prior to the Effective Time multiplied by the
       Option Exchange Ratio and (ii) the per share exercise price for the
       shares of Parent Common Stock issuable upon exercise of such assumed
       Company Stock Option will be equal to the quotient (rounded up to the
       nearest whole cent) determined by dividing the exercise price per share
       of Company Common Stock at which such Company Stock Option was
       exercisable immediately prior to Closing by the Option Exchange Ratio.
       For purposes of this SECTION 6.10(a) the term "OPTION EXCHANGE RATIO"
       shall mean the sum of (x) the Stock Portion, and (y) the quotient
       determined by dividing the Cash Portion by the fair market value of one
       (1) share of Parent Common Stock, as determined at the Effective Time.

           (ii) As promptly as practicable (but in no event more than 30
       calendar days) following the Effective Time, Parent shall file, if
       available for use by Parent, a registration statement on

                                      A-41

       all shares of Parent Common Stock issuable upon the exercise of the
       Company Stock Options assumed by Parent pursuant to SECTION 6.9(a)
       hereof.

        (b)  COMPANY ESPP.  The Company shall take all steps necessary or
    appropriate (as determined by Parent) to terminate the Company ESPP on
    either (i) the day immediately prior to the Effective Time, or (ii) the last
    day of the last full payroll period ending immediately prior to the
    Effective Time.

    6.11  EMPLOYEE MATTERS.

        (a) The Company shall terminate, effective as of the day immediately
    preceding the date the Company becomes a member of the same Controlled Group
    of Corporations (as defined in Section 414(b) of the Code) as Parent (the
    "401(K) TERMINATION DATE"), any and all 401(k) plans maintained by the
    Company or any of its subsidiaries unless Parent shall provide notice to the
    Company that any such 401(k) plan(s) shall not be terminated pursuant to
    this SECTION 6.11. The Company shall provide Parent evidence that the 401(k)
    plan(s) of the Company and its subsidiaries have been terminated pursuant to
    resolutions of the Company Board or the board of directors of its
    subsidiaries, as applicable (the form and substance of such resolutions
    shall be subject to review and approval of Parent), effective as of the
    401(k) Termination Date. All employees of the Company shall continue on
    their existing benefit plans until such time as, in Parent's sole
    discretion, an orderly transition can be accomplished to employee benefit
    plans and programs maintained by Parent for its and its affiliates'
    employees. Pending such action, Parent shall maintain the effectiveness of
    the Company's benefit plans.

        (b) To the extent permitted under applicable law, each employee of the
    Company or its subsidiaries who shall become an employee of Parent in
    connection with the Merger shall be given credit for all service with the
    Company or its subsidiaries (or service credited by the Company or its
    subsidiaries) under all employee benefit plans, programs, policies and
    arrangements maintained by Parent or the Surviving Corporation (other than
    sabbatical benefits, for which employees of the Company or its subsidiaries
    will not receive any such past service credit) in which they participate or
    in which they become participants for purposes of eligibility and vesting;
    PROVIDED, HOWEVER, that no such credit shall be provided in any circumstance
    that would result in duplicative benefits, and PROVIDED, FURTHER, HOWEVER,
    that such insurance carriers, outside providers or the like are able to
    honor such commitments or terms reasonably acceptable to Parent.

        (c) The Company shall terminate any and all group severance, separation
    or salary continuation plans, programs or arrangements maintained by the
    Company or any of its subsidiaries, effective in each case as of the day
    immediately preceding the Effective Time. The Company shall provide Parent
    evidence that such plans have been terminated pursuant to resolutions of the
    Company Board or the board of directors of its subsidiaries, as applicable
    (the form and substance of which resolutions shall be subject to review and
    approval of Parent).

    6.12  RIGHTS PLAN AMENDMENT.

        (a) From the date of this Agreement until the earlier to occur of the
    termination Agreement pursuant ARTICLE VIII hereof or the Effective Time,
    the Company and the Company Board shall not amend or modify, or take any
    other action with regard to the Company Rights Plan in any manner, or take
    any other action so as to (i) render the Company Rights Plan inapplicable to
    any transaction other than the Merger and other transactions contemplated by
    this Agreement and the Company Voting Agreements and the transactions
    contemplated thereby, or (ii) permit any person (other than Parent, Merger
    Sub or any of their affiliates) who would otherwise be an Acquiring Person
    (as defined in the Company Rights Plan) not to be an Acquiring Person
    thereunder, or (iii) provide that a Distribution Date or a Stock Acquisition
    Date (as such terms are defined in the

                                      A-42
<PAGE>
    Company Rights Plan) or similar event does not occur as promptly as
    practicable by reason of the execution of any agreement or transaction other
    than this Agreement and the Company Voting Agreements and the Merger and the
    agreements and transactions contemplated hereby and thereby, or (iv) except
    as specifically contemplated by this Agreement, otherwise affect the rights
    of holders of Company Rights, or (v) otherwise render the Company Rights
    Plan applicable to Parent or its affiliates.

        (b) In the event that this Agreement is terminated pursuant to
    ARTICLE VIII hereof or otherwise (other than the termination of this
    Agreement by the Company pursuant to SECTION 8.1(c)(I) hereof) the Company
    shall not, for a period of six months from such termination, amend, modify,
    terminate or otherwise rescind the Rights Plan Amendment without the prior
    written consent of Parent.

    6.13  DIRECTORS' AND OFFICERS' INDEMNIFICATION.

        (a) For a period six (6) years from and after the Effective Time, Parent
    shall cause the Surviving Corporation to fulfill and honor in all respects
    the obligations of the Company under any indemnification agreements between
    the Company and its directors and officers in effect immediately prior to
    the Effective Time (the "COMPANY INDEMNIFIED PARTIES") and any
    indemnification provisions under the Company Charter Documents as in effect
    on the date hereof to the maximum extent permitted by applicable law. The
    Certificate of Incorporation of the Surviving Corporation shall contain
    provisions with respect to exculpation and indemnification that are at least
    as favorable to the Company Indemnified Parties as those contained in the
    Company Charter Documents as in effect on the date hereof, which provisions
    shall not be amended, repealed or otherwise modified in any manner that
    would adversely affect the rights thereunder of individuals who, immediately
    prior to the Effective Time, were directors, officers, employees or agents
    of the Company, unless such modification is required by applicable law.

        (b) For a period of six (6) years from and after the Effective Time,
    Parent shall cause the Surviving Corporation to maintain in effect, if
    available, directors' and officers' liability insurance covering those
    persons who are currently covered by the Company's directors' and officers'
    liability insurance policy in an amount and on terms no less advantageous,

           (i) the Merger shall not have been consummated on or before
       October 31, 2001 (the "TERMINATION DATE"); PROVIDED, HOWEVER, that in the
       event that the Merger shall not have been consummated on or before
       October 31, 2001 solely as a result of the failure to obtain all
       regulatory Approvals required to consummate the Merger, the Termination
       Date shall be extended for two successive thirty (30) calendar day
       periods (provided that in no event will the Termination Date be extended

       to terminate this Agreement pursuant to this SECTION 8.1(b)(I) shall not
       be available to any party hereto whose failure to fulfill any obligation
       under this Agreement has been the principal cause of, or resulted in the
       failure of, the Merger to have been consummated on or before the
       Termination Date and such action or failure to act constitutes a material
       breach of this Agreement; or

           (ii) the Requisite Company Stockholder Approval shall not have been
       obtained by reason of the failure to obtain the required vote at a
       meeting of the Company stockholders duly convened therefor or at any
       adjournment thereof; PROVIDED, HOWEVER, that the right to terminate this
       Agreement under this SECTION 8.1(b)(II) shall not be available to the
       Company where the failure to obtain the Requisite Company Stockholder
       Approval shall have been caused by the action or failure to act of the
       Company and such action or failure to act constitutes a material breach
       by the Company of this Agreement; or

          (iii) there shall have been enacted, issued, promulgated or enforced
       any law, rule or regulation that makes the consummation of the Merger
       illegal, or any judgment, injunction, order or decree of any Governmental
       Entity having competent jurisdiction permanently restraining, enjoining
       or otherwise prohibiting Parent or the Company from consummating the
       Merger, and such judgment, injunction, order or decree shall have become
       final and nonappealable.

        (c) by the Company:

           (i) in the event of a material breach of any covenant or agreement on
       the part of Parent or Merger Sub set forth in this Agreement, or in the
       event that any representation or warranty of Parent and Merger Sub set
       forth in this Agreement shall have been inaccurate when made or shall
       have become inaccurate, in either case such that the condition set forth
       in SECTION 7.2 hereof would not be satisfied as of the time of such
       breach or as of the time such representation or warranty shall have
       become untrue; PROVIDED, HOWEVER, that notwithstanding the foregoing, in
       the event that such breach by Parent or Merger Sub or such inaccuracies
       in the representations and warranties of Parent or Merger Sub are curable
       by Parent or Merger Sub through the exercise of its commercially
       reasonable efforts, then the Company shall not be permitted to terminate
       this Agreement pursuant to this SECTION 8.1(c)(I) until the earlier to
       occur of (A) the expiration of a thirty (30) calendar day period after
       delivery of written notice from the Company to Parent of breach or
       inaccuracy, as applicable, or (B) Parent or Merger Sub ceasing to
       exercise commercially reasonable efforts to cure such breach or
       inaccuracy,

                                      A-47

       SECTION 8.1(c)(I) if such breach or inaccuracy by Parent or Merger Sub is
       cured within such thirty (30) calendar day period); or

           (ii) prior to entering into a definitive agreement with respect to an
       Superior Proposal, provided that (A) the Company has not breached and is

       current version of such definitive agreement and the identity of the
       person making such Superior Proposal, all with the purpose and intent of
       enabling Parent and the Company to discuss in good faith a modification
       of the terms and conditions of this Agreement so that the transactions
       contemplated hereby may be effected, (D) Parent does not make, within
       five (5) business days after receipt of the Company's written notice of
       its intention to enter into a definitive agreement with respect to such
       Superior Proposal, an offer that the Company Board reasonably determines
       in good faith, after consultation with a financial advisor of nationally
       recognized standing and its outside legal counsel, is at least as
       favorable to Company's stockholders as such Superior Proposal, and
       (E) concurrently with the termination of this Agreement, the Company pays
       to Parent the Termination Fee set forth in SECTION 8.4 hereof and enters
       into a definitive agreement with respect to such Superior Proposal.

           (i) in the event of a material breach of any covenant or agreement on
       the part of the Company set forth in this Agreement, or in the event that
       any representation or warranty of the Company set forth in this Agreement
       shall have been inaccurate when made or shall have become inaccurate, in
       either case such that the condition set forth in SECTION 7.3 hereof would
       not be satisfied as of the time of such breach or as of the time such
       representation or warranty shall have become untrue; PROVIDED, HOWEVER,
       that notwithstanding the foregoing, in the event that such breach by the
       Company or such inaccuracies in the representations and warranties of the
       Company are curable by the Company through the exercise of its
       commercially reasonable efforts, then Parent shall not be permitted to
       terminate this Agreement pursuant to this SECTION 8.1(d)(I) until the
       earlier to occur of (A) the expiration of a thirty (30) calendar day
       period after delivery of written notice from Parent to the Company of
       such breach or inaccuracy, as applicable, or (B) the ceasing by the
       Company to exercise commercially reasonable efforts to cure such breach
       or inaccuracy, provided that the Company continues to exercise
       commercially reasonable efforts to cure such breach or inaccuracy (it
       being understood that Parent may not terminate this Agreement pursuant to
       this SECTION 8.1(d)(I) if such breach or inaccuracy by the Company is
       cured within such thirty (30) calendar day period); or

    of a tender offer or an exchange offer or issuance by the Company), directly
    or indirectly, of beneficial ownership or a right to acquire beneficial
    ownership of shares representing in excess of fifty percent (50%) of the
    voting power of the then outstanding shares of capital stock of the Company.

        (d)  ENFORCEABILITY.  The Company hereby acknowledges that the
    agreements set forth in this SECTION 8.3 are an integral part of the
    transactions contemplated by this Agreement, and that, without such
    agreements, Parent would not enter into this Agreement. Accordingly, if the
    Company shall fail to pay in a timely manner the amounts due pursuant to
    this SECTION 8.3, and, in order to obtain such payment, Parent makes a claim
    that results in a judgment against the Company, the Company shall pay to
    Parent its reasonable costs and expenses (including reasonable attorneys'
    fees and expenses) in connection with such suit, together with interest on
    the amounts set forth in this SECTION 8.3 at the base rate established by
    Citibank, N.A. in effect on the date such payment was required to be made.
    Payment of the fees set forth in this SECTION 8.3 shall not be in lieu of
    damages incurred in the event of breach of this Agreement.

    8.4  AMENDMENT.  Subject to applicable law, this Agreement may be amended by
the parties hereto at any time by execution of an instrument in writing signed
on behalf of each of Parent, Merger Sub and Company.

    8.5  EXTENSION; WAIVER.  At any time prior to the Effective Time any party
hereto may, to the extent legally allowed and except as otherwise set forth
herein, (i) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party. Delay in exercising any right under this Agreement shall not constitute a
waiver of such right.

    9.6  ENTIRE AGREEMENT; THIRD PARTY BENEFICIARIES.  This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Schedule and the
Parent Schedule (a) constitute the entire agreement among the parties with
respect to the subject matter hereof and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof, it being understood that the Confidentiality Agreement
shall continue in full force and effect until the Closing and shall survive any

person any rights or remedies hereunder.

    9.7  SEVERABILITY.  In the event that any provision of this Agreement, or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably

such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or injunctions to prevent
breaches of this Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having jurisdiction, this
being in addition to any other remedy to which they are entitled at law or in
equity.

accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws.

HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE ACTIONS OF PARENT, MERGER SUB OR THE COMPANY
IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS
AGREEMENT.

    9.13  CONSENT TO JURISDICTION.  Each of the parties hereto irrevocably
