same repurchase option, risk of forfeiture or other condition, and the
certificates representing such shares of Parent Common Stock shall accordingly
be marked with appropriate legends. The Company shall take all action that may
be necessary to ensure that, from and after the Effective Time, Parent is
entitled to exercise any such repurchase option or other right set forth in any
such restricted stock purchase agreement or other agreement.

        1.6 EMPLOYEE STOCK OPTIONS. At the Effective Time, each then outstanding
Company Option and each other outstanding option to purchase Common Stock of the
Company issued in accordance with the terms of this Agreement, whether vested or
unvested, shall be assumed by Parent in accordance with the terms (as in effect
as of the date of this Agreement or, for options issued to new employees after
the date of this Agreement, as in effect on the date of issuance) of such
Company Stock Option Plan under which such Company Option was issued and the
stock option agreement by which such Company Option is evidenced. All rights
with respect to Company Common Stock under outstanding Company Options shall
thereupon be converted into rights with respect to Parent Common Stock.
Accordingly, from and after the Effective Time, (a) each Company Option assumed
by Parent may be exercised solely for shares of Parent Common Stock, (b) the
number of shares of Parent Common Stock subject to each such assumed Company
Option shall be equal to the number of shares of Company Common Stock that were
subject to such Company Option immediately prior to the Effective Time
multiplied by the Applicable Fraction, rounded down to the nearest whole number
of shares of Parent Common Stock, and (c) the per share exercise price for the
Parent Common Stock issuable upon exercise of each such assumed Company Option
shall be determined by dividing the exercise price per share of Company Common
Stock subject to such Company Option, as in effect immediately prior to the
Effective Time, by the Applicable Fraction, and rounding the resulting exercise
price up to the nearest whole cent, and all restrictions on the exercise of each
such assumed Company Option shall continue in full force and effect, and the
term, exercisability, vesting schedule and other provisions of such Company
Option shall otherwise remain unchanged; provided however, that each such
assumed Company Option shall, in accordance with its terms, be subject to
further adjustment as appropriate to reflect any stock split, reverse stock
split, stock dividend, recapitalization or other similar transaction effected by
Parent after the Effective Time. The Company and Parent shall take all action
that may be necessary (under the Company Stock Option Plan and otherwise) to
effectuate the provisions of this Section 1.6.

        1.7 CLOSING OF THE COMPANY'S TRANSFER BOOKS. At the Effective Time,
holders of certificates representing shares of capital stock of the Company that
were outstanding immediately prior to the Effective Time shall cease to have any
rights as stockholders of the Company, and the stock transfer books of the
Company shall be closed with respect to all shares of such capital stock of the
Company outstanding immediately prior to the Effective Time. No further transfer
of any such shares of capital stock of the Company shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any shares of capital stock of the Company
(a "Company Stock Certificate") is presented to the Surviving Corporation or
Parent, such Company Stock Certificate shall be canceled and shall be exchanged
as provided in Section 1.8.



                                       4.

        1.8    EXCHANGE OF CERTIFICATES.

               (a) As soon as practicable after the Effective Time, Parent will
send to each of the registered holders of Company Stock Certificates a letter of
transmittal in customary form and containing such customary provisions as Parent
may reasonably specify and instructions for use in effecting the surrender of
Company Stock Certificates in exchange for the Merger Consideration. Upon
surrender of a Company Stock Certificate to Parent for exchange, together with a
duly executed letter of transmittal and such other customary documents as may be
reasonably required by Parent, Parent shall (i) deliver to the holder of such
Company Stock Certificate a certificate representing 92.5% of that number of
shares of Parent Common Stock that such holder has the right to receive pursuant
to Section 1.5, and (ii) deliver to the Escrow Agent under the Escrow Agreement
(as defined below) on behalf of such holder a certificate in the name of the
Escrow Agent representing 7.5% of that number of shares of Parent Common Stock
that such holder has the right to receive pursuant to Section 1.5, provided that
the certificates representing Parent Common Stock to be delivered to the holder
of a Company Stock Certificate under clause (i) above and to the Escrow Agent
under clause (ii) above shall, in each case, represent only whole shares of
Parent Common Stock. In lieu of any fractional shares to which such holder would
otherwise be entitled, after combining any fractional interests of such holder
into as many whole shares as is possible, the holder of such Company Stock
Certificate shall be paid in cash an amount equal to the sum of (1) the dollar
amount (rounded to the nearest whole cent) determined by multiplying the Closing
Sales Price (as defined below) by the fraction of a share of Parent Common Stock
that would otherwise be deliverable to such holder under clause (i) above and
(2) the dollar amount (rounded to the nearest whole cent) determined by
multiplying the Closing Sales Price by the fraction of a share of Parent Common
Stock that would otherwise be deliverable to the Escrow Agent under clause (ii)
above. Notwithstanding the foregoing, Parent may deliver to the Escrow Agent one
certificate representing the total number of shares of Parent Common Stock to be
held in escrow pursuant to this Section 1.8(a) in lieu of issuing separate
certificates representing such holder's Escrow Shares. As used in this
Agreement, the "Closing Sales Price" shall mean the closing sales price of one
share of Parent Common Stock as quoted on the Nasdaq on the last trading day
immediately preceding the Closing Date. All Company Stock Certificates so
surrendered shall be canceled. Until surrendered as contemplated by this Section
1.8, each Company Stock Certificate shall be deemed, from and after the
Effective Time, to represent only the right to receive the Merger Consideration
in accordance with this Agreement. If any Company Stock Certificate shall have
been lost, stolen or destroyed, Parent may, in its discretion and as a condition
precedent to the issuance of any certificate representing Parent Common Stock or
the payment of cash in lieu of fractional shares, require the owner of such
lost, stolen or destroyed Company Stock Certificate to provide an appropriate
affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as
indemnity against any claim that may be made against Parent or the Surviving
Corporation with respect to such Company Stock Certificate.

               (b) No dividends or other distributions declared or made with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Company Stock Certificate with
respect to the shares of Parent Common Stock represented thereby, and no cash
payment in lieu of any fractional share shall be paid to any such holder, until
such holder surrenders such Company Stock Certificate in accordance with



                                       5.
<PAGE>   13

this Section 1.8 (at which time such holder shall be entitled to receive all
such dividends and distributions and such cash payment).

               (c) Parent and the Surviving Corporation shall be entitled to
deduct and withhold from any consideration payable or otherwise deliverable to
any holder or former holder of capital stock of the Company pursuant to this
Agreement such amounts as Parent or the Surviving Corporation may be required to
deduct or withhold therefrom under the Code or under any provision of state,
local or foreign tax law, provided that Parent or the Surviving Corporation pays
to the applicable government authority in accordance with applicable Legal
Requirements, the amount so withheld. 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.

               (d) Neither Parent nor the Surviving Corporation shall be liable
to any holder or former holder of capital stock of the Company for any shares of
Parent Common Stock (or dividends or distributions with respect thereto), or for
any cash amounts, delivered to any public official pursuant to any applicable
abandoned property, escheat or similar law.

        1.9    DISSENTERS' RIGHTS.

               (a) Notwithstanding anything in this Agreement to the contrary,
shares of capital stock of the Company held by a holder who, pursuant to
Subchapter XIII of the WBCL or any successor provision, has the right to dissent
to the Merger and demand payment for such shares and properly dissents and
demands payment for the fair value of such shares of capital stock of the
Company ("Dissenting Shares") in accordance with the WBCL, shall not be
converted into the right to receive Parent Common Stock as set forth in Section
1.5, unless such holder withdraws, fails to perfect or otherwise loses such
holder's right to such payment, if any. If, after the Effective Time, such
holder withdraws, fails to perfect or loses any such right to payment, such
holder's Dissenting Shares shall be treated as having been converted as of the
Effective Time into the right to receive the Merger Consideration. At the
Effective Time, any holder of Dissenting Shares shall cease to have any rights
with respect thereto, except the rights provided in Subchapter XIII of the WBCL
or any successor provision and as provided in the immediately preceding
sentence. The Company shall give prompt notice to Parent of any demands received
by the Company for appraisal of shares of capital stock of the Company and the
opportunity to participate in all negotiations and proceedings with respect to
any such demand. Except to the extent otherwise required by the WBCL, the
Company shall not make any payment or settlement offer prior to the Effective
Time with respect to any such demand unless Parent shall have consented in
writing to such payment or settlement offer.

        1.10 ESCROW OF PARENT COMMON STOCK. Upon the Closing, Parent shall
withhold the shares of Parent Common Stock to be delivered to the Escrow Agent
pursuant to Section 1.8(a)(ii) (the "Escrow Shares") and deliver such shares to
La Salle Bank National Association as escrow agent (the "Escrow Agent"), to be
held by the Escrow Agent as collateral to secure the rights of the Indemnitees
under Section 9 hereof. The Escrow Shares shall be held pursuant to the
provisions of an escrow agreement substantially in the form of EXHIBIT B (the
"Escrow Agreement"). The Escrow Shares will be represented by a certificate or
certificates



                                       6.
<PAGE>   14

issued in the name of the Escrow Agent and will be held by the Escrow Agent for
a period to end on the earlier of (i) one year from the Closing Date and (ii)
the completion of the first audit of the combined financial statements of Parent
and the Company covering periods following the Closing (the earlier of (i) and
(ii), "Escrow Period"); provided however that in the event any Indemnitee has
made a claim under Section 9 prior to the end of the Escrow Period, then the
Escrow Period shall continue (and the Escrow Agent will continue to hold, in
accordance with Section 3(a) of the Escrow Agreement, a certain number of shares
in escrow) until such claim is fully and finally resolved. In the event that
this Agreement is adopted by the Company's stockholders, then all such
stockholders shall, without any further act of any Company stockholder, be
deemed to have consented to and approved (i) the use of the Escrow Shares as
collateral to secure the rights of the Indemnitees under Section 9 in the manner
set forth herein and in the Escrow Agreement, and (ii) the appointment of the
Company Stockholders' Representative (as defined in Section 10.1) as the
representative under the Escrow Agreement of the Persons receiving Merger
Consideration under this Agreement and as the attorney-in-fact and agent for and
on behalf of each such Person (other than holders of Dissenting Shares).

        1.11 TAX CONSEQUENCES. For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code. The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

        1.12 ACCOUNTING TREATMENT. For accounting purposes, the Merger is
intended to be treated as a "pooling of interests."

        1.13 FURTHER ACTION. If, at any time after the Effective Time, any
further action is determined by Parent to be necessary or desirable to carry out
the purposes of this Agreement and any Related Agreement or to vest the
Surviving Corporation or Parent with full right, title and possession of and to
all rights and property of Merger Sub and the Company, the officers and
directors of the Surviving Corporation and Parent shall be fully authorized (in
the name of Merger Sub, in the name of the Company and otherwise) to take such
action.

scope of its coverage) that is substantially identical to the form of Employee
Agreement Relating to Intellectual Property and Confidential Information
previously delivered to Parent. No current or former employee, officer,
director, stockholder, consultant or independent contractor of or to the Company

products to an unlimited number of parties, and none of such products has at any
time infringed, misappropriated or made any unlawful or unauthorized use of,
(iv) the Company has not received any notice or other communication (in writing
or otherwise) of any actual, alleged, possible or potential infringement,
misappropriation or unlawful or unauthorized use of, any Proprietary Asset owned
or used by any other Person and (v) no other Person is infringing,
misappropriating or making any unlawful or unauthorized use of, and no
Proprietary Asset owned or used by any other Person infringes or conflicts with,
any material Company Proprietary Asset.

               (d) The Company Proprietary Assets constitute all the Proprietary
Assets necessary to enable the Company to conduct its business in the manner in
which such business has been and is being conducted. Except as set forth in Part
2.9(d) of the Company Disclosure Schedule, the Company has not (i) licensed any
of the material Company Proprietary Assets to any Person on an exclusive basis,
or (ii) entered into any covenant not to compete or Contract limiting its
ability to exploit fully any material Company Proprietary Assets or to transact
business in any market or geographical area or with any Person.

               (e) Except as set forth in Part 2.9(e)(i) of the Company
Disclosure Schedule, the Company has not disclosed or delivered to any Person,
or permitted the disclosure or delivery to any escrow agent or other Person, of
any Company Source Code. No event has occurred, and no circumstance or condition
exists, that (with or without notice or lapse of time) will, or could reasonably
be expected to, result in the disclosure or delivery to any Person of any
Company Source Code. Part 2.9(e)(ii) of the Company Disclosure Schedule
identifies each Contract pursuant to which the Company has deposited or is
required to deposit with an escrowholder or any other Person any Company Source
Code, and further describes whether the execution of this Agreement or the
consummation of any of the transactions contemplated hereby could reasonably be

Section 341(f) of the Code. The Company has not been, and the Company will not
be, required to include any adjustment in taxable income for any tax period (or
portion thereof) pursuant to Section 481 or 263A of the Code or any comparable
provision under state or foreign Tax laws as a result of transactions or events
occurring, or accounting methods employed, prior to the Closing.

               (c) Each of the Employee Plans intended to be qualified under
Section 401(a) or 501(c)(9) of the Code has received a favorable determination
letter from the Internal Revenue Service (the "IRS:) as to its qualified status

the Internal Revenue Service for such a determination letter prior to the
expiration of the requisite period under applicable Treasury Regulations or
Internal Revenue Service pronouncements in which to apply for such a
determination letter and to make any amendments necessary to obtain a favorable
determination, and nothing has occurred since the issuance of each such letter
which could reasonably be expected to cause the loss of the tax-qualified status
of any Employee Plan.

               (d) Neither the Company nor any of its ERISA Affiliates has ever
maintained, adopted, established, contributed or been required to contribute to,

any of the Employee Plans. All contributions required to be made by the Company
and/or any other ERISA Affiliate to any Employee Plan have been made on or
before their due dates and a reasonable amount has been accrued for
contributions to each Employee Plan for the current plan year. No "reportable
event" within the meaning of Section 4043 of ERISA (excluding any such event for

4041, 4062 or 4063 of ERISA has occurred with respect to any Employee Plan. No
suit, administrative proceeding, action or other claim has been brought or is
threatened against or with respect to any Employee Plan, including any audit or
inquiry by the IRS or United States Department of Labor.

               (g) The Company does not have any plan or commitment to create
any additional Employee Plan, or to modify or change any existing Employee Plan
(other than to comply with applicable law) in a manner that would affect any
current or former employee, consultant or director of the Company or any other
ERISA Affiliate, and there has been no amendment to, written interpretation or
announcement (whether or not written) by the Company or any other ERISA
Affiliate relating to, or change in participation or coverage, under any
Employee Plan which would materially increase the expense of maintaining such
Employee Plan above the level of expense incurred with respect to that Employee
Plan for the most recent fiscal year.

               (h) None of the Employee Plans promises or provides death,
medical or health benefits (whether or not insured) with respect to any current
or former Employee, consultant or director of the Company or any other ERISA
Affiliate after any such Employee's, consultant's or director's termination of
service other than (i) benefit coverage mandated by applicable law, including
coverage provided pursuant to Section 4980B of the Code, and (ii) deferred
compensation benefits accrued as liabilities on the Audited Balance Sheet.

               (i) With respect to each Employee Plan constituting a group
health plan within the meaning of Section 4980B(g)(2) of the Code, the
provisions of Section 4980B of the Code ("COBRA") and Sections 601-609 of ERISA
have been complied with in all material respects.

               (j) Except as set forth in Part 2.15(j) of the Company Disclosure

the Related Agreements, nor the consummation of the Merger or any of the other
transactions contemplated by this



                                      21.

Agreement and the Related Agreements, will result in any liability to the
Company or any other ERISA Affiliate or payment (including any bonus, golden
parachute or severance payment) to any current or former employee, consultant or
director of the Company (whether or not under any Employee Plan), or increase
the benefits payable under any Employee Plan, or result in any acceleration of
the time of payment or vesting of any such benefits.

               (k) Part 2.15(k) of the Company Disclosure Schedule contains a

material respects with the applicable requirements of the Securities Act or the
Exchange Act (as the case may be); and (ii) none of the Parent SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

year-end audit adjustments; and (iii) fairly present the consolidated financial
position of Parent as of the respective dates thereof and the consolidated

Agreement under this Section 8.1(d) on account of an inaccuracy in the Company's
representations and warranties or on account of a breach of a covenant by the
Company if such inaccuracy or breach is curable by the Company unless the
Company fails to cure such inaccuracy or breach within 15 days after receiving
written notice from Parent of such inaccuracy or breach;

               (e) by the Company if any of Parent's representations and
warranties contained in this Agreement shall have been materially inaccurate as
of the date of this Agreement or shall have become materially inaccurate as of
any subsequent date (as if made on such subsequent date), or if any of Parent's
covenants contained in this Agreement shall have been breached in any material
respect; provided, however, that the Company may not terminate this Agreement
under this Section 8.1(e) on account of an inaccuracy in Parent's
representations and warranties or on account of a breach of a covenant by Parent
if such inaccuracy or breach is curable unless Parent fails to cure such
inaccuracy or breach within 15 days after receiving written notice from the
Company of such inaccuracy or breach; or

               (f) by Parent or the Company if the Closing has not taken place
on or before May 10, 2001 (the "Termination Date") (other than as a result of
any failure on the part of the terminating party to comply with or perform any
of its covenants or obligations set forth in this Agreement).

        8.2 TERMINATION PROCEDURES. If either party wishes to terminate this
Agreement pursuant to Section 8.1, it shall deliver to the other party a written
notice stating that it is terminating this Agreement and (except for termination
under Section 8.1(f) which will not require such certification) setting forth a
brief description of the basis on which it is terminating this Agreement.

        8.3 EFFECT OF TERMINATION. If this Agreement is terminated pursuant to
Section 8.1, all further obligations of the parties under this Agreement shall
terminate; provided, however, that: (a) neither the Company nor Parent shall be
relieved of any obligation or liability arising from any inaccuracy or prior
breach by such party of any representation, warranty, covenant or other
provision of this Agreement; (b) the parties shall, in all events, remain bound
by and continue to be subject to the provisions set forth in Section 10; (c) the
parties shall, in all events, remain bound by and continue to be subject to

9.      INDEMNIFICATION, ETC.

        9.1    SURVIVAL OF REPRESENTATIONS, ETC.

               (a) The representations and warranties made by the Company
(including the representations and warranties set forth in Section 2 and the
representations set forth in the Company Compliance Certificate) shall survive
the Closing and shall expire at the end of the Escrow Period; provided, however,
that if, at any time prior to the end of the Escrow Period, any Indemnitee
delivers to the Company Stockholders' Representative a written notice alleging
the existence of an inaccuracy in or a breach of any of the representations and
warranties made by the Company (and setting forth in reasonable detail the basis
for such Indemnitee's belief that such an inaccuracy or breach may exist) and
asserting a claim for recovery under Section 9.2 based on such alleged
inaccuracy or breach, then the representation or warranty underlying the claim
asserted in such notice shall survive the end of the Escrow Period until such
time as such claim is fully and finally resolved. All representations and
warranties made by Parent and Merger Sub shall terminate and expire as of the
Effective Time, and any liability of Parent or Merger Sub with respect to such
representations and warranties shall thereupon cease.

               (b) The representations, warranties, covenants and obligations of
the Company, and the rights and remedies that may be exercised by the
Indemnitees, shall not be limited or otherwise affected by or as a result of any
information furnished to, or any investigation made by or knowledge of, any of
the Indemnitees or any of their Representatives; provided, however, that Parent
shall be deemed to have knowledge of the information specifically included in
the Company Disclosure Schedule on the date of this Agreement, excluding any
information included in any updates to the Company Disclosure Schedules after
the date of this Agreement.

               (c) For purposes of this Section 9, each statement or other item
of information set forth in the Company Disclosure Schedule or in any update to
the Company Disclosure Schedule shall be deemed to be a representation and
warranty made by the Company in this Agreement.

        9.2    INDEMNIFICATION.

               (a) From and after the Closing Date (but subject to Section
9.1(a)), each Indemnitee shall be held harmless and shall be indemnified from
and against, and shall be compensated, reimbursed and paid for, any Damages
which are suffered or incurred by any Indemnitee or to which any Indemnitee may
otherwise become subject (regardless of whether or not such Damages relate to
any third-party claim) and which arise from or as a result of, or are directly
or indirectly connected with: (i) any inaccuracy in or breach of any
representation or warranty of the Company set forth in this Agreement or in the
Company Compliance Certificate (in each case, without giving effect to any
update to the Company Disclosure Schedule delivered by the Company to Parent
prior to the Closing); (ii) any breach of any covenant or obligation of the
Company (including the covenants set forth in Sections 4 and 5); or (iii) any
Legal Proceeding relating to any inaccuracy or breach of the type referred to in
clauses "(i)" or "(ii)"



                                      42.
<PAGE>   50

above (including any Legal Proceeding commenced by any Indemnitee for the
purpose of enforcing any of its rights under this Section 9).

               (b) In the event the Surviving Corporation suffers, incurs or
otherwise becomes subject to any Damages as a result of or in connection with
any inaccuracy in or breach of any representation, warranty, covenant or
obligation, then (without limiting any of the rights of the Surviving
Corporation as an Indemnitee) Parent shall also be deemed, by virtue of its
ownership of the stock of the Surviving Corporation, to have incurred Damages as
a result of and in connection with such inaccuracy or breach.

        9.3 THRESHOLD. No Indemnitee shall be entitled to indemnification
pursuant to Section 9.2(a) for any inaccuracy in or breach of any of the
Company's representations and warranties set forth in this Agreement or the
Company Compliance Certificate until such time as the total amount of all
Damages (including the Damages arising from such inaccuracy or breach and all
other Damages arising from any other inaccuracies in or breaches of any
representations or warranties) that have been directly or indirectly suffered or
incurred by any one or more of the Indemnitees, or to which any one or more of
the Indemnitees has or have otherwise become subject, exceeds $750,000 in the
aggregate, provided that if the total amount of such Damages exceeds $750,000,
then any Indemnitee that has suffered or incurred any Damages shall be entitled
to be held harmless, indemnified against and compensated, reimbursed and paid
only for such Damages exceeding $750,000.

        9.4 OFFSET AGAINST ESCROW SHARES; SOLE REMEDY. Subject to Section 9.3,
in the event any Indemnitee shall suffer any Damages for which such Indemnitee
is entitled to indemnification under this Section 9, such Indemnitee shall be
entitled to recover such Damages solely by obtaining that number of Escrow
Shares equal in value (as determined in accordance with the terms and conditions
of the Escrow Agreement) to the aggregate amount of such Damages, and such
recovery shall be made from the Escrow Shares on a basis proportional to the
Escrow Shares contributed under the Escrow Agreement by or on behalf of each
Company stockholder. The Company stockholders shall have no liability for
Damages in excess of the number of Escrow Shares held under the Escrow Agreement
except for Damages directly or indirectly related to fraud, intentional
misrepresentation or any willful breach of this Agreement.

        9.5 NO CONTRIBUTION. The Company stockholders shall not have and shall
not exercise or assert (or attempt to exercise or assert), any right of
contribution, right of indemnity or other right or remedy against the Surviving
Corporation in connection with any indemnification obligation or any other
liability to which such stockholders may become subject under or in connection
with this Agreement or the Escrow Agreement.

               (a) DEFENSE OF THIRD PARTY CLAIMS. In the event of the assertion
or commencement by any Person of any claim or Legal Proceeding (whether against
the Surviving Corporation, against Parent or against any other Person) with
respect to which any of the Indemnitees may be entitled to indemnification or
any other remedy pursuant to this Section 9, Parent shall promptly give the
Company Stockholders' Representative and the Escrow Agent written notice of such
claim or Legal Proceeding (a "Claim") provided, however, that any failure on the
part of Parent to so notify the Company Stockholders' Representative shall not
limit



                                      43.
<PAGE>   51

any of the Indemnitees' rights to indemnification under this Section 9 (except
to the extent such failure materially prejudices the defense of such Legal
Proceeding).

               (b) Within ten days of delivery of such written notice, the
Company Stockholders' Representative may elect (by written notice delivered to
Parent) to take all necessary steps properly to contest any Claim involving
third parties or to prosecute such Claim to conclusion or settlement. If the
Company Stockholders' Representative makes the foregoing election, an Indemnitee
will have the right to participate at its own expense in all proceedings. If the
Company Stockholders' Representative does not make such election within such
period or fails to diligently contest such Claim after such election, then the
Indemnitee shall be free to handle the prosecution or defense of any such Claim,
and will take all necessary steps to contest the Claim involving third parties
or to prosecute such Claim to conclusion or settlement, and will notify the
Company Stockholders' Representative of the progress of any such Claim, will
permit the Company Stockholders' Representative, at the sole cost of the Company
Stockholders' Representative, to participate in such prosecution or defense and
will provide the Company Stockholders' Representative with reasonable access to
all relevant information and documentation relating to the Claim and the
prosecution or defense thereof.

               (c) Notwithstanding the foregoing, if a Claim includes Damages
equal to an amount in excess of the value of the Escrow Shares on the date of
the Claim, or relates to any Proprietary Assets or other intellectual property
issues, Parent shall have the right, at its election, to proceed with the
defense of such claim or Legal Proceeding on its own. In any case, the party not
in control of the Claim will cooperate with the other party in the conduct of
the prosecution or defense of such Claim.

               (d) Neither party will compromise or settle any such Claim
without the written consent of either Parent (if the Company Stockholders'
Representative defends the Claim) or the Company Stockholders' Representative
(if Parent or other Indemnitees defend the Claim), such consent not to be
unreasonably withheld. Parent shall have the right, at its election, to proceed
with the defense of such claim or Legal Proceeding on its own. If Parent
proceeds with the defense of any such claim or Legal Proceeding all reasonable
expenses relating to the defense of such claim or Legal Proceeding shall be
satisfied first out of the Escrow Shares in the manner set forth in the Escrow
Agreement and then from the Company stockholders.

        9.6 EXERCISE OF REMEDIES BY INDEMNITEES OTHER THAN PARENT. No Indemnitee
(other than Parent or any successor thereto or assign thereof) shall be
permitted to assert any indemnification claim or exercise any other remedy under
this Agreement or under the Escrow Agreement unless Parent (or any successor
thereto or assign thereof) shall have consented to the assertion of such
indemnification claim or the exercise of such other remedy.

10.     MISCELLANEOUS PROVISIONS

        10.1   COMPANY STOCKHOLDERS' REPRESENTATIVE.

               (a) The stockholders of the Company, by adopting this Agreement
and the Escrow Agreement and the transactions contemplated hereby and thereby,
hereby irrevocably appoint Ralph Kauten as their agent and attorney-in-fact for
purposes of Section 9 and the



                                      44.
<PAGE>   52

Escrow Agreement (the "Company Stockholders' Representative"), and consent to
the taking by the Company Stockholders' Representative of any and all actions
and the making of any decisions required or permitted to be taken by him under
Section 9 hereof or the Escrow Agreement (including, without limitation, the
exercise of the power to authorize delivery to Parent of the Escrow Shares in
satisfaction of claims by Parent, agree to, negotiate, enter into settlements
and compromises of and demand arbitration, and comply with orders of courts and
awards of arbitrators with respect to such claims, resolve any claim made
pursuant to Section 9; and take all actions necessary in the judgment of the
Company Stockholders' Representative for the accomplishment of the foregoing).
By his execution below, Ralph Kauten hereby accepts his appointment as the
Company Stockholders' Representative for purposes of Section 9 and the Escrow
Agreement. Parent shall be entitled to deal exclusively with the Company
Stockholders' Representative on all matters relating to Section 9 and the Escrow
Agreement, and shall be entitled to rely conclusively (without further evidence
of any kind whatsoever) on any document executed or purported to be executed on
behalf of any Company stockholder by the Company Stockholders' Representative,
and on any other action taken or purported to be taken on behalf of any Company
stockholder by the Company Stockholders' Representative, as fully binding upon
such Company stockholder.

               (b) If the Company Stockholders' Representative shall die, become
disabled or otherwise be unable to fulfill his responsibilities as agent of the
Company stockholders, then 780 Partners shall, within ten days after such death
or disability, appoint a successor representative reasonably satisfactory to
Parent. Any such successor shall become the "Company Stockholders'
Representative" for purposes of Section 9, the Escrow Agreement and this Section
10.1. If for any reason there is no Company Stockholders' Representative at any
time, all references herein to the Company Stockholders' Representative shall be
deemed to refer to 780 Partners. The parties acknowledge that 780 Partners is an
investment partnership comprised of attorneys with the law firm of Godrey &
Kahn, S.C., which has acted as counsel to the Company in connection with this
Merger Agreement. The parties hereby understand that there may be a potential
conflict of interest in the event that 780 Partners is appointed as the Company
Stockholders' Representative and the parties hereby waive any such conflict.

               (c) A Company Stockholders' Representative shall not be liable
for any act done or omitted hereunder as Company Stockholders' Representative
while acting in good faith and in the exercise of reasonable judgment. Company
stockholders on whose behalf Escrow Shares were contributed to the escrow shall
severally indemnify each Company Stockholders' Representative and hold each
Company Stockholders' Representative harmless against any loss, liability or
expense incurred without gross negligence, bad faith or willful misconduct on
the part of such Company Stockholders' Representative and arising out of or in
connection with the acceptance or administration of such Company Stockholders'
Representative's duties hereunder, including the reasonable fees and expenses of
any legal counsel retained by such Company Stockholders' Representative.

               (d) The Company Stockholders' Representative shall be entitled to
rely upon any order, judgment, certificate, demand, notice, instrument or other
writing delivered to it hereunder without being required to investigate the
validity, accuracy or content thereof nor shall the Company Stockholders'
Representative be responsible for the validity or sufficiency of this



                                      45.
<PAGE>   53

Agreement. In all questions arising under this Agreement, the Company
Stockholders' Representative may rely on the advice of counsel, and for anything
done, omitted or suffered in good faith by the Company Stockholders'
Representative based on such advice, the Company Stockholders' Representative
shall not be liable to anyone.

        10.2 FURTHER ASSURANCES. Each party hereto shall execute and cause to be
delivered to each other party hereto such instruments and other documents, and
shall take such other actions, as such other party may reasonably request (prior
to, at or after the Closing) for the purpose of carrying out or evidencing any
of the transactions contemplated by this Agreement.

        10.3 FEES AND EXPENSES. Each party to this Agreement shall bear and pay
all fees, costs and expenses (including legal fees and accounting fees) that
have been incurred or that are incurred by such party in connection with the
transactions contemplated by this Agreement, including all fees, costs and
expenses incurred by such party in connection with or by virtue of (a) the
investigation and review conducted by Parent and its Representatives with
respect to the Company's business (and the furnishing of information to Parent
and its Representatives in connection with such investigation and review), (b)
the negotiation, preparation and review of this Agreement (including the Company
Disclosure Schedule) and all agreements, certificates, opinions and other
instruments and documents delivered or to be delivered in connection with the
transactions contemplated by this Agreement, (c) the preparation and submission
of any filing or notice required to be made or given in connection with any of
the transactions contemplated by this Agreement, and the obtaining of any
Consent required to be obtained in connection with any of such transactions, and
(d) the consummation of the Merger; provided however, that, to the extent the
total amount of all such fees, costs and expenses incurred by or for the benefit
of the Company (including all such fees, costs and expenses incurred prior to
the date of this Agreement and including the amount of all special bonuses and
other amounts that may become payable to any officers of the Company or other
Persons in connection with the consummation of the transactions contemplated by
this Agreement) exceeds one million dollars ($1,000,000) in the aggregate, such
fees, costs and expenses shall be paid and satisfied by the cancellation of that
number of Escrow Shares in accordance with the terms of the Escrow Agreement
equal in value to the total of such fees, costs and expenses in excess of one
million dollars ($1,000,000).

        10.4 ATTORNEYS' FEES. If any action or proceeding relating to this
Agreement or the enforcement of any provision of this Agreement is brought
against any party hereto, the prevailing party shall be entitled to recover
reasonable attorneys' fees, costs and disbursements (in addition to any other
relief to which the prevailing party may be entitled).

State of California (and each appellate court located in the State of
California), in connection with any legal proceeding;

                      (ii) agrees that service of any process, summons, notice

                      (iii) agrees that each state and federal court located in

        10.10 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and

<PAGE>   56

power, right, privilege or remedy and no single or partial exercise of any such
power, right, privilege or remedy shall preclude any other or further exercise
thereof or of any other power, right, privilege or remedy. No Person shall be
deemed to have waived any claim arising out of this Agreement, or any power,
right, privilege or remedy under this Agreement, unless the waiver of such
claim, power, right, privilege or remedy is expressly set forth in a written
instrument duly executed and delivered on behalf of such Person; and any such
waiver shall not be applicable or have any effect except in the specific
instance in which it is given.

        10.13 AMENDMENTS. This Agreement may not be amended, modified, altered

matter hereof and thereof and supersede all prior agreements and understandings
