claim or right or any benefit arising thereunder or resulting therefrom if an
attempted assignment thereof, without consent of a third party thereto, would
constitute a breach or other contravention thereof or in any way adversely
affect the rights of Buyer, Parent or Seller thereunder. Parent, Seller and
Buyer will use their commercially reasonable efforts (but without any payment of
money by Parent, Seller or Buyer) to obtain the consent of the other parties to
any such Purchased Asset or claim or right or any benefit arising thereunder for
the assignment thereof to Buyer as Buyer may request. If such consent is not
obtained, or if an attempted assignment thereof would be

<PAGE>

ineffective or would adversely affect the rights of Seller thereunder so that
Buyer would not in fact receive all such rights, Parent, Seller and Buyer will
cooperate in a mutually agreeable arrangement under which Buyer would obtain the
benefits and assume the obligations thereunder in accordance with this
Agreement, including subcontracting, sub-licensing, or subleasing to Buyer, or
under which Parent or Seller would enforce for the benefit of Buyer, with Buyer
assuming either Parent's or Seller's obligations, any and all rights of Parent
or Seller against a third party thereto. Parent or Seller, as the case may be,
will promptly pay to Buyer when received all monies received by Parent or Seller
under any Purchased Asset or any claim or right or any benefit arising
thereunder, except to the extent the same represents an Excluded Asset. In such
event, Parent, Seller and Buyer shall, to the extent the benefits therefrom and
obligations thereunder have not been provided by alternate arrangements
satisfactory to Buyer, Parent and Seller, negotiate in good faith an adjustment
in the consideration paid by Buyer for the Purchased Assets.

          (b) Notwithstanding any other provision of this Agreement, including
the foregoing, subsection 2.05(a), the parties agree that with respect to the
Contracts listed on Schedule 2.05(b) hereto the following shall apply:

               (i) Parent, Seller and Buyer shall use their reasonable
commercial efforts to secure the consent of the third party customers on such

                                   ---------

--------
into the Escrow Fund at Closing. The Purchase Price Holdback shall be released
to Parent upon the assignment to Buyer of the Contracts listed on Schedule
2.05(b) hereto in such amounts and at such times as described following.

               (iii) When such of the Contracts listed on Schedule 2.05(b) have
been assigned to Buyer such that the aggregate total "future billings" and
"deferred revenues" in the amounts as listed on Schedule 2.05(b) (without
subsequent adjustment) for all Contracts not yet assigned (such amounts being
referred to as the "Measurement Amounts"), shall be less than $729,176, Parent
                    -------------------
shall be entitled to receive out of the Escrow Fund $1.37 for every $1.00 below
such $729,176 to which the Measurement Amounts related to as yet unassigned
Contracts shall drop (to the extent not previously paid as provided following
and up to a total amount of payments as shall equal the Purchase Price
Holdback). Any Contract listed on Schedule 2.05(b) which has an expiration date
after June 30, 2002, shall be deemed to have been assigned for all purposes
under this Section 2.05 if Buyer and the customer under such Contract shall have
entered into a similar agreement or renewal of the Contract on terms not
substantially less favorable than those of the Contract, whether or not a
Special Assignment shall have been executed for such Contract.

Contracts which have been assigned through and including June 30, 2002 shall be
released from the Escrow Fund. The balance, if any, of the Purchase Price
Holdback, which shall not be required to be released to Parent pursuant to this
Section 2.05 shall be released to Buyer and shall be a reduction in the Purchase
Price. To the extent that the final Measurement Amounts related to unassigned

source (the "Software Programs"). Seller or Parent, as the case may be, owns
             -----------------
full and unencumbered right and good and marketable title to such Software
Programs which it owns, free and clear of all mortgages, pledges, liens,

from disabling codes. The Systems' components used in connection with the
Business obtained by Seller from third party suppliers are, to the best of

portion thereof. Except with respect to the rights of third parties to any
Licensed Intellectual Property, no third party has rights to manufacture,
reproduce, distribute, market or exploit any works or materials of any portion
of the Intellectual Property if such portion of the Intellectual Property
constitutes a "derivative work" (as that term is defined in the United States
Copyright Act, Title 17, U.S.C. Section 101) of an underlying work of
authorship. Except as set forth in Schedule 3.15(e), neither Seller nor Parent
owes or will owe any royalties or other payment to third parties in respect of

without the assistance of any third party or entity or were created by third
parties who assigned ownership of their rights to Seller or Parent pursuant to
valid and enforceable consultant confidentiality and invention assignment
agreements. Seller and Parent have at all times treated the Intellectual
Property as containing trade secrets and has not disclosed or otherwise dealt
with such items in such a manner as to cause the loss of such trade secrets by
release into the public domain, including without limitation, the use of
confidentiality agreements with all of its employees having access to the
Intellectual Property and the use of licenses with all individuals or entities
provided access to the Intellectual Property containing provisions restricting
copying and prohibiting decompiling or disassembly of the Intellectual Property.

employee with Seller or any other party. No current officer, director, employee,

Section 3.21(c), Tax (and the correlative meanings, "Taxes," "Taxable" and
"Taxing") shall not include any amount to the extent that (A) a lien, claim or
encumbrance cannot be placed upon any of the Purchased Assets with respect to
such amount and (B) neither Buyer nor any of its affiliates can be made directly
or indirectly liable with respect to such amount.

     Buyer hereby represents and warrants to each of Seller and Parent, subject
to the exceptions specifically disclosed in writing in the corresponding

Buyer of this Agreement and each of the Ancillary Agreements, and the

Buyer is a party have been, or will be in the case of the Ancillary Agreements,
duly executed and delivered by Buyer and constitute valid and binding agreements
of Buyer, enforceable against Buyer in accordance with their respective terms,
except as may be limited by any bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or other similar law affecting the enforcement
of creditors' rights generally or by general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     4.03 Non-Contravention. The execution, delivery and performance by Buyer of
          -----------------
this Agreement and each of the Ancillary Agreements to which Buyer is a party do
not and will not (i) contravene or conflict with the organizational documents or
bylaws of Buyer, (ii) contravene or conflict with or constitute a violation of

                            COVENANTS OF the parties

     5.01 Best Efforts; Further Assurances.
          --------------------------------

          (a) Subject to the terms and conditions of this Agreement and except
as otherwise set forth in this Agreement, each party will use its best efforts
to take, or cause to be taken, all actions and to do, or cause to be done, all
things necessary or desirable under applicable laws and regulations to
consummate the transactions contemplated by this Agreement. Parent, Seller and
Buyer each agree to execute and deliver such other documents, certificates,
agreements and other writings and to take such other actions as may be necessary
or desirable in order to consummate or implement expeditiously the transactions
contemplated by this Agreement and to vest in Buyer title to the Purchased
Assets as provided herein.

          (b) Seller hereby constitutes and appoints, effective as of the
Closing Date, Buyer and its successors and assigns as the true and lawful
attorney of Seller with full power of substitution in the name of Buyer or in
the name of Seller, but for the benefit of Buyer, except as otherwise
contemplated hereby, (i) to collect for the account of Buyer any items of
Purchased Assets and (ii) to institute and prosecute all proceedings which Buyer
may in its sole discretion deem proper in order to assert or enforce any right,
title or interest in, to or under the Purchased Assets, and to defend or
compromise any and all actions, suits or proceedings in respect of the Purchased
Assets. Buyer shall be entitled to retain for its account any amounts collected
pursuant to the foregoing powers, including any amounts payable as interest in
respect thereof.

          (c) At Buyer's request, Seller and Parent shall maintain as active all
internet website links or any and all websites maintained by them which link to
any websites pertaining to the Business for a period of up to thirty days
following the Closing. Seller and Parent agree to provide such other termination
services as may relate to the Business as may be reasonably requested by Buyer
at Buyers expenses.

          (d) Seller and Parent shall provide the data to be transferred to
Buyer out of the Shared Systems to Buyer in such electronic and other formats as
Buyer may reasonably request and Seller and Parent shall maintain such data in
the Shared Systems for such reasonable amount of time following the Closing as
Buyer may request.

     5.02 Certain Filings. Parent, Seller and Buyer shall cooperate with one
          ---------------
another and shall use all reasonable efforts and take all reasonable steps to
obtain all consents, approvals, waivers or other documents from any third
parties, including any governmental authorities, and make all filings,
registrations and other notifications, as may be required to consummate the
transactions contemplated by this Agreement and, in taking such actions or
making any such filings, furnishing information required in connection therewith
and seeking timely to obtain any such actions, consents, approvals or waivers.

     5.03 Confidentiality. The parties hereto shall comply with, and shall cause
          ---------------
their respective Representatives to comply with, all of their respective
obligations under the Confidentiality Agreement with respect to the information
disclosed pursuant to this Agreement

                                       20

<PAGE>

provided however, that, the parties shall be permitted to make such disclosures
as they shall reasonably determine are, and to the extent, required by law.

     5.04 Nonsolicitation by Seller and Parent. Each of Seller and Parent agrees
          ------------------------------------
that, for a period of one (1) year following the Closing Date, neither Seller
nor Parent shall solicit or induce the employment or services of any Transferred
Employee without the prior written consent of Buyer, provided, however, that
nothing in this Section 5.04 shall be construed as prohibiting Seller or Parent
from conducting any general solicitation (including by placing advertisements in
any form or method not targeted at employees or independent contractors of
Buyer). Notwithstanding the foregoing, if Buyer terminates the employment of any
Transferred Employee, either Seller or Parent shall be permitted to solicit such
terminated employee.

     5.05 [Intentionally Deleted]

     5.06 Name Change. From and after the Closing, Seller and Parent will cease
          -----------
using the name "AdRelevance" and thereafter will not use any substantially
similar or confusingly similar names or include them in any logo. In addition,
promptly after the Closing, Seller will change its corporate name to a name that
does not contain the word "AdRelevance" or any substantially similar or
confusingly similar name, and will file that name change in all state
jurisdictions in which Seller has presently registered the name for purposes of
maintaining its corporate business and doing business as a foreign corporation.

     5.07 Informational Updates. Buyer agrees that it shall provide Parent and
          ---------------------
Seller with such information and take such other action, as may reasonably be
requested by Parent or Seller from time to time, in connection with Parent's
reporting obligations to any governmental authority.

     5.08 Covenant Not To Compete.
          -----------------------

          (a) Each of Seller and Parent covenants and agrees that, except as
permitted under this Section 5.08, for a period of three years after the Closing
Date, it will not, and will cause its subsidiaries not to, engage in the
Business anywhere in the world; provided, however, that nothing herein shall be
construed to prevent Seller or Parent or any of their respective subsidiaries
from owning as a passive investor up to five percent (5%) in any person that
engages in the Business. It is the desire and intent of the parties that the
provisions of this Section 5.08 shall be enforced to the fullest extent
permitted under the laws and public policies of each jurisdiction in which
enforcement is sought. If any court determines that any provision of this
Section 5.08 is unenforceable, such court shall have the power to reduce the
duration or scope of such provision, as the case may be, or terminate such
provision and, in reduced form, such provision shall be enforceable; it is the
intention of the parties that the foregoing restrictions shall not be
terminated, unless so terminated by a court, but shall be deemed amended to the
extent required to render them valid and enforceable, such amendment to only
apply with respect to the operation of this Section 5.08 in the jurisdiction of
the court that has made the adjudication.

          (b) The parties acknowledge and agree that the restrictions contained
in this Section 5.08 are a reasonable and necessary protection of the immediate
interest of Buyer, and any violation of these restrictions would cause
substantial injury to Buyer and Buyer would not

                                       21

<PAGE>

have entered into this Agreement without receiving the additional consideration
offered by Seller and Parent in binding itself to these restrictions. In the
event of a breach or a threatened breach by Seller or Parent or any of their
respective subsidiaries of these restrictions, Buyer shall be entitled to apply
to any court of competent jurisdiction for an injunction restraining such person
from such breach or threatened breach (without the necessity of providing the
inadequacy of money damages as a remedy); provided, however, that the right to
apply for injunctive relief shall not be construed as prohibiting Buyer from
pursuing any other available remedies for such breach or threatened breach.

     5.09 Mail and Communications. Seller and Parent will promptly remit to
          -----------------------
Buyer any mail or other communications received by Seller or Parent relating to
the Business or the Purchased Assets and any invoices received by Seller or
Parent relating to Assumed Liabilities which are received by Seller or Parent
from and after the Closing Date. Buyer will promptly remit to Parent any mail or
other communications, including, without limitation, any written inquiries and
payments received by Buyer relating to the Excluded Assets or to any business or
activity of Parent other than the Business, and any invoices received by Buyer
relating to liabilities of Seller or Parent other than the Assumed Liabilities
which are received by Buyer from and after the Closing Date.

     5.10 Public Announcements. The initial press release concerning the
          --------------------
transactions contemplated hereby shall be a joint press release approved by the
parties to this Agreement.

     5.11 Taxes.
          -----

          (a) Parent and Seller shall pay all Taxes imposed upon Parent and
Seller. Parent and Seller shall also pay, or indemnify Buyer for, all Taxes
imposed on Buyer or any affiliate of Buyer and any Taxes to which the Purchased
Assets are subject or for which a lien, claim or encumbrance can be placed upon
the Purchased Assets but only in each case to the extent that any such Taxes
relate to periods (or portions thereof) ending on or prior to the Closing Date
or transactions or events occurring on or prior to the Closing Date and only to
the extent related to the Business and including any sales or transfer taxes
regardless of which party may be the legal obligor under applicable law.
Liability for any Taxes that Seller is required to satisfy pursuant to this
Section 5.11 shall not constitute or be treated as Assumed Liabilities.

          (b) Seller and Parent shall properly file all Tax Returns that they
are required by any applicable law to file with respect to Taxes arising in or
related to periods on or prior to the Closing Date or related to transactions or
events occurring prior to the Closing Date by the due date (including
extensions) for such returns. With respect to state and local ad valorem taxes
on the Purchased Assets (whether personal or real, owned or leased) for the
current Tax year, Seller and Parent shall as provided in Section 2.04 be
responsible for the payment of all such Taxes for the period up to and including
the Closing Date and Buyer shall be responsible for the payment of all such
Taxes for the period after the Closing Date. For all purposes of this Agreement,
(i) all such Taxes assessed on an annual basis shall be prorated on the
assumption that an equal amount of Tax applies to each day of the year,
regardless of how installment payments are billed or made and (ii) any
supplemental property Taxes or assessments which arise out of a revaluation of a
Purchased Asset which revaluation would not have occurred except for the change
in ownership of the Purchased Asset shall be allocated to periods after the
Closing Date and shall accordingly

                                       22

<PAGE>

be borne by Buyer. Any payment of Taxes due from one party to the other pursuant
to the foregoing provisions of this Section 5.11 shall be paid at the Closing
Date. If the current year's Taxes and assessments are not available at the
Closing Date, for the purposes of apportionment between Seller, Parent and Buyer
and payment pursuant to this Section 5.11, the amount thereof shall be estimated
on the basis of the prior year's Taxes and assessments, and any incremental
payment shall be adjusted after receipt of the final Tax statements, but within
fifteen (15) days after such statements are provided by the tax authorities. For
purposes of this Agreement income and similar Taxes (including any franchise or
other Taxes measured by reference to income or receipts) for any taxable period
that includes the Closing Date shall be allocated to the period up to and
including the Closing Date, on the one hand, and the period following the
Closing Date, on the other hand, by utilizing the so-called closing of the books
method whereby the tax for each of such periods is separately computed as though
the Closing Date constituted the end of a taxable period.

          (c) Buyer agrees to take all actions reasonably requested by Seller
and Parent to minimize any sales, use and other transfer taxes and fees incurred
in connection with the assignment, conveyance, transfer and/or delivery of the
Purchased Assets hereunder (collectively, the "Sales Taxes"), including, without
limitation the transfer via means of electronic transmission of all assets
capable of being so transmitted. Buyer further agrees to deliver all
certificates reasonably requested by Seller and Parent to verify the fact of
such electronic transmissions or other actions. Seller and Parent shall be
responsible for the payment of the amount of any Sales Taxes.

     5.12 Cooperation and Records Retention. Seller, Parent and Buyer shall (i)
          ---------------------------------
each provide the other with such assistance as may reasonably be requested by
them in connection with the preparation of any Tax Returns, or in connection
with any audit or other examination by any taxing authority or any judicial or
administrative proceedings relating to liability for Taxes, (ii) each retain and
provide the other, with any records or other information which may be relevant
to any such Tax Return, audit or examination, proceeding or determination, and
(iii) each provide the other with any final determination of any such audit or
examination, proceeding or determination that affects any amount required to be
shown on any Tax Return of the other for any period. Without limiting the
generality of the foregoing, Seller, Parent and Buyer shall retain, until the
applicable statute of limitations (including any extensions) have expired,
copies of all Tax Returns, supporting work schedules and other records or
information which may be relevant to such Tax Returns for all tax periods or
portions thereof ending before or including the Closing Date and shall not
destroy or otherwise dispose of any such records without first providing the
other party with a reasonable opportunity to review and copy the same. Buyer
shall keep the original copies of the records and, at Seller's expense, shall
provide copies of the records to Seller upon Seller's request.

                                EMPLOYEE BENEFITS


     6.01 Employees and Offers of Employment.
          ----------------------------------

                                       23

<PAGE>

          (a) Prior to Closing Date, but effective as of the Closing, Buyer
shall make offers of employment to the employees of Parent and Seller primarily
engaged in the Business and set forth on Schedule 6.01(a) (each such person,
upon accepting an offer of employment from Buyer, a "Transferred Employee").
                                                     --------------------
Each such offer shall include (i) base salary or base wages which is the same as
was in effect immediately prior to the Closing Date and (ii) employee benefits
(other than as set forth in clause (i)) which are the same as those provided to
similarly situated employees of Buyer. Nothing in this Agreement shall limit the
right of Buyer to terminate the employment of any Transferred Employee following
the Closing Date.

          (b) As of the Closing Date, all Transferred Employees shall cease
active participation in all Employee Plans and Benefit Arrangements. As soon as
administratively feasible following the Closing Date and in accordance with the
terms of the applicable benefit plans or programs of Buyer and Affiliates, all
Transferred Employees shall be permitted to participate in the plans, programs
and arrangements of Buyer and its Affiliates relating to compensation and
employee benefits (each, a "Buyer Plan") on the same terms as similarly situated
                            ----------
employees of Buyers and its Affiliates.

          (c) Effective as of the Closing, Buyer shall credit each Transferred
Employee with the number of vacation days accrued and not used as of the Closing
by such Transferred Employee.

     6.02 Distribution of 401(k) Plan Accounts. Seller agrees that pursuant to
          ------------------------------------
Code Section 401(k)(2), the Acquisition will result in, and constitute, a
distribution event for Transferred Employees who participate in the 401(k)
plan(s) maintained by Seller or any ERISA Affiliate (the "401(k) Plan"). Seller
further agrees that as soon as administratively feasible following the Closing
Date, Transferred Employees who participate in the 401(k) Plan shall be provided
the opportunity to take a distribution from the 401(k) Plan.

     6.03 Employee NonCompetition Agreements. Parent and Seller agree that
          ----------------------------------
following the Closing all rights which either of them or any of their affiliates
may have to prevent any employees being transferred to Buyer from working in the
Business or competing therewith shall not be enforced without the consent of
Buyer. To the extent such rights have not been transferred to Buyer pursuant to
this Agreement, each of Buyer and Seller shall cooperate with Buyer, at Buyer's
expense and upon Buyer's request, to enforce such rights.

                                   ARTICLE VII

                              CONDITIONS TO CLOSING

     7.01 Conditions to the Obligations of Each Party. The obligations of Buyer,
          -------------------------------------------
Parent and Seller to consummate the transactions contemplated hereby are subject
to the satisfaction of the following conditions:

          (a) Buyer, Parent, Seller and any other parties thereto shall have
executed and delivered to the other this Agreement and each of the Ancillary
Agreements.

                                       24

<PAGE>

          (b) Each party shall have received such closing documents as it may
reasonably request, all in form and substance reasonably satisfactory to such
requesting party.

                                  ARTICLE VIII

                            SURVIVAL; INDEMNIFICATION

     8.01 Survival. The covenants, agreements, representations and warranties of
          --------
the parties hereto contained in this Agreement or in any certificate or other
writing delivered pursuant hereto or in connection herewith shall survive the
Closing until twelve (12) months after the Closing Date or (i) in the case of
Section 5.08 (Covenant Not To Compete) for the period set forth therein; or (ii)
in the case of the covenants, agreements, representations and warranties
contained in Articles V and VI, until expiration of the applicable statutory
period of limitations (giving effect to any waiver, mitigation or extension
thereof), if later. Notwithstanding the preceding sentence, any covenant,
agreement, representation or warranty in respect of which indemnity may be
sought under Sections 8.02 shall survive the time at which it would otherwise
terminate pursuant to the preceding sentence, if notice of the inaccuracy or
breach thereof giving rise to such right to indemnity shall have been given to
the party against whom such indemnity may be sought prior to such time.

     8.02 Indemnification.
          ---------------

          (a) Seller and Parent hereby indemnify Buyer and its officers,
directors, employees and agents against, and agrees to hold each of them
harmless from, any and all damages, claims, debts, actions, assessments,
judgments, losses, liabilities, fines, fees, penalties and expense (including,
without limitation, reasonable expenses of investigation and reasonable
attorneys' fees and expenses in connection with any action, suit or proceeding)
(collectively, "Losses") incurred or suffered by any of them arising out of:
                ------

               (i) any misrepresentation or breach of representation and
warranty, covenant or agreement made or to be performed by Seller or Parent
pursuant to this Agreement or the Ancillary Agreements; and

               (ii) the failure of Seller or Parent to assume full
responsibility for any Excluded Liability or any obligation or liability of the
Business relating to the Excluded Assets and failure to pay and discharge when
due any Excluded Liability, or any claim or cause of action by any party against
such indemnities with respect to the Excluded Liability.

          (b) Buyer hereby indemnifies Seller and its Affiliates and its
officers, directors, employees and agents against, and agrees to hold each of
them harmless from, any and all Losses incurred or suffered by such parties
arising out of:

               (i) any misrepresentation or breach of representation and
warranty, covenant or agreement made or to be performed by Buyer pursuant to
this Agreement or the Ancillary Agreements; and

                                       25

<PAGE>

               (ii) the failure of Buyer to assume full responsibility for any
Assumed Liability or any obligation or liability of the Business relating to the
Purchased Assets and failure to pay and discharge when due any Assumed
Liability, or any claim or cause of action by any party against such indemnities
with respect to the Assumed Liability.

          (c) Buyer shall be entitled to retain funds from the Escrow Fund
pursuant to Section 2.05 related to the non-assignment of any Contracts pursuant
to Section 2.05. To the extent that the aggregate Measurement Amounts related to
any unassigned Contracts shall exceed $729,176, Buyer shall have a claim for
losses against the Escrow Fund in an amount equal to $1.37 for every $1.00 in
excess of such $729,176.

          (d) Notwithstanding anything in this Agreement to the contrary,
neither Seller or Parent on the one hand, nor Buyer on the other hand, shall be
liable under this Article VIII unless and until the aggregate Losses (without
giving effect to any materiality or material adverse effect qualifications or
materiality exceptions contained in any provision of this Agreement) to any
Indemnified Person incurred or suffered by them resulting from, relating to or
constituting any misrepresentation or breach of warranty contained in this
Agreement or the Ancillary Agreements exceed $100,000, and then such liability
shall be only for Losses in excess of such amount. Except with respect to claims
based on fraud, the indemnification obligations for all Losses resulting from,
relating to or constituting any misrepresentation, breach of warranty or failure
to perform any covenant or agreement of Seller, Parent or Buyer, as applicable,
shall be limited to the $5,000,000. Notwithstanding anything in this Agreement
to the contrary, any claims by Buyer for indemnification for any Taxes shall not
be subject to the foregoing limitation on recovery. Losses related to Buyer's
right to indemnification regarding unassigned Contracts as provided in Section
8.02 (c) and any release of Purchase Price Holdback from the Escrow Fund
pursuant to Section 2.05 shall not be subject to the foregoing $100,000
deductible limitation on recovery but shall be subject to the total $5,000,000
limitation.

          (e) The indemnification obligations of the parties set forth in this
Article VIII shall constitute the sole and exclusive remedy of the parties for
the recovery of money damages with respect to any and all matters arising out of
this Agreement. The parties agree that the Purchase Price Holdback amount held
in the Escrow Fund shall not be available for buyer claims for indemnification
and that the Escrow Funds shall be available to satisfy buyer's claims pursuant
to Section 8.02(c) to

     8.03 Procedures; No Waiver; Exclusivity.
          ----------------------------------

          (a) All claims for indemnification by an Indemnified Person pursuant
to this Article VIII shall be made in accordance with the provisions of this
Section 8.03.

          (b) A party entitled to indemnification under this Article VIII (the
"Indemnified Person") shall give prompt written notification to the Person
 ----------- ------
obligated to provide such indemnification (the "Indemnifying Person") of the
                                                -------------------
commencement of any action, suit or proceeding relating to a third party claim
for which indemnification pursuant to this Article VIII may be sought; provided,
however, that no delay on the part of the Indemnified Person in notifying the
Indemnifying Person shall relieve the Indemnifying Person from any liability or
obligation under this Article VIII except to the extent of any damage or
liability caused solely by

                                       26

<PAGE>

or arising out of such delay. Within 20 days after delivery of such
notification, the Indemnifying Person may, upon written notice thereof to the
Indemnified Person, assume control of the defense of such action, suit or
proceeding with counsel reasonably satisfactory to the Indemnified Person,
provided (i) the Indemnifying Person acknowledges in writing to the Indemnified
Person that the Indemnifying Person shall indemnify the Indemnified Person with
respect to all elements of such action, suit or proceeding and any damages,
fines, costs or other liabilities that may be assessed against the Indemnified
Person in connection with such action, suit or proceeding, and (ii) the third
party seeks monetary damages only. If the Indemnifying Person does not so assume
control of such defense, the Indemnified Person shall control such defense. The
party not controlling such defense may participate therein at its own expense;
provided, that if the Indemnifying Person assumes control of such defense and
the Indemnified Person is advised by counsel in writing that the Indemnifying
Person and the Indemnified Person may have conflicting interests or different
defenses available with respect to such action, suit or proceeding, the
reasonable fees and expenses of counsel to the Indemnified Person shall be
considered "Losses" for purposes of this Agreement. The party controlling such
defense shall keep the other party advised of the status of such action, suit or
proceeding and the defense thereof and shall consider in good faith
recommendations made by the other party with respect thereto. An Indemnified
Person shall not agree to any settlement of such action, suit or proceeding
without the prior written consent of the Indemnifying Person, which shall not be
unreasonably withheld or delayed. The Indemnifying Person shall not agree to any
settlement or the entry of a judgment in any action, suit or proceeding without
the prior written consent of the Indemnified Person, which shall not be
unreasonably withheld (it being understood that it is reasonable to withhold
such consent if, among other things, the settlement or the entry of a judgment
(A) lacks a complete release of the Indemnified Person for all liability with
respect thereto or (B) imposes any liability or obligation on the Indemnified
Person). If Parent or Seller shall have consented to any settlement as provided
herein, they shall forfeit their right to object to any Buyer Claim against the
Escrow Fund for recovery of such amounts.

     8.04 Escrow Fund. As security for the indemnity provided by Parent and
          -----------
Seller for the benefit of Parent in Section 8.02 hereof, $375,000 of the
Purchase Price plus the Purchase Price Holdback amount shall be deposited by
Buyer in an interest-bearing escrow account with J. P. Morgan Trust Company,
N.A. (or other mutually acceptable institution) as Escrow Agent (the "Escrow
Agent"), as of the Closing Date, all such funds deposited to constitute an
escrow fund (the "Escrow Fund") to be governed by the terms set forth in this
Agreement and the provisions of an Escrow Agreement, in the form attached hereto
as Exhibit E, to be executed and delivered pursuant hereto. Upon compliance with
the terms hereof and subject to the provisions of Sections 8.04 through 8.10
hereof, Buyer shall be entitled to obtain from the Escrow Fund indemnity for
Losses covered by the indemnity provided for in Section 8.02 hereof.

     8.05 Escrow Period. The Escrow Period shall terminate at the expiration of
          -------------
one year after the Closing (the "Termination Date"); provided, however, that the
funds held in escrow related to the Purchase Price Holdback amount shall be
released as provided in Section 2.05. Notwithstanding the forgoing, such portion
of the Escrow Fund, which is necessary to satisfy any unsatisfied claims
specified in any Officer's Certificate (as defined in Section 8.06 below)
theretofore delivered to the Escrow Agent prior to termination of the Escrow
Period with respect to facts and circumstances existing prior to expiration of
the Escrow Period, shall remain in the Escrow Fund until such claims have been
finally resolved.

     8.06 Claims Upon Escrow Fund. Upon receipt by the Escrow Agent on or before
          -----------------------
the Termination Date of a certificate signed by the chief financial or chief
executive officer of Buyer (an "Officer's Certificate"):

          (a) stating that Buyer has incurred, paid or properly accrued (in
accordance with generally accepted accounting principles ("GAAP")) or knows of
facts giving rise to a reasonable probability that it will have to incur, pay or
accrue (in accordance with GAAP) Losses in an aggregate stated amount with
respect to which Buyer is entitled to payment from the Escrow Fund pursuant to
this Agreement; and

          (b) specifying in reasonable detail the individual items of Losses
included in the amount so stated, the date each such item was incurred, paid or
properly accrued (in accordance with GAAP), or the basis for such anticipated
liability, and the specific nature of the breach to which such item is related,

the Escrow Agent shall, subject to the provisions of Section 8.07 of this
Agreement, deliver to Buyer the amount of Escrow Funds necessary to indemnify
Buyer for the Losses claimed; provided, however, that Escrow Funds shall not be
delivered to Buyer as a result of a claim based upon an accrual or upon a
reasonable probability of having to incur, pay or accrue Losses until such time
as the Buyer has actually incurred or paid Losses. All Escrow Funds subject to
such claims shall remain in the Escrow Fund until Losses are actually incurred
or paid or the Buyer determines in its reasonably good faith judgment that no
Losses will be required to be incurred or paid (in which event such Escrow Funds
shall be distributed to Seller in accordance with the terms of the Escrow
Agreement).

     8.07 Objections to Claims. At the time of delivery of any Officer's
          --------------------
Certificate to the Escrow Agent, a duplicate copy of such Officer's Certificate
shall be delivered to the Seller and for a period of fifteen (15) days after
such delivery to the Escrow Agent, the Escrow Agent shall make no delivery of
the Escrow Funds pursuant to Section 8.06 hereof unless the Escrow Agent shall
have received written authorization from the Seller to make such delivery. After
the expiration of such fifteen (15) day period, the Escrow Agent shall make
delivery of the Escrow Funds in accordance with Section 8.06 hereof, provided
that no such payment or delivery may be made if the Seller shall object in a
written statement to the claim made in the Officer's Certificate, and such
statement shall have been delivered to the Escrow Agent and to Buyer prior to
the expiration of such fifteen (15) day period.

     8.08 Resolution of Conflicts; Arbitration.
          ------------------------------------

          (a) In case Seller shall so object in writing to any claim or claims
by Buyer made in any Officer's Certificate, Seller and Buyer shall attempt in
good faith for sixty (60) days to agree upon the rights of the respective
parties with respect to each of such claims. If Seller and Buyer should so
agree, a memorandum setting forth such agreement shall be prepared and signed by
both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall
be entitled to rely on any such memorandum and shall distribute the Escrow Funds
in accordance with the terms thereof.

                                       28

<PAGE>

          (b) If no such agreement can be reached after good faith negotiation,
either Buyer or Seller may, by written notice to the other, demand arbitration
of the matter unless the amount of the Losses is at issue in pending litigation
with a third party, in which event arbitration shall not be commenced until such
amount is ascertained or both parties agree to arbitration; and in either such
event the matter shall be settled by arbitration conducted by three arbitrators.
Within fifteen (15) days after such written notice is sent, Buyer and Seller
shall each select one arbitrator, and the two arbitrators so selected shall
select a third arbitrator. The decision of the arbitrators as to the validity
and amount of any claim in such Officer's Certificate shall be binding and
conclusive upon the parties to this Agreement, and notwithstanding anything in
Section 8.06 hereof, the Escrow Agent shall be entitled to act in accordance
with such decision and make or withhold payments out of the Escrow Fund in
accordance therewith.

          (c) Judgment upon any award rendered by the arbitrators may be entered
in any court having jurisdiction. Any such arbitration shall be held in San
Mateo County, California under the commercial rules then in effect of the
American Arbitration Association. Buyer and Seller shall share equally all fees
and expenses of the arbitrators.
