2.6(c) and 6.3(j) below, at the Effective Time, by virtue of the Merger and
without any action on the part of any person, each share of the Company Common
Stock (assuming the issuance of Company Common Stock upon the conversion or
exercise, as the case may be, of all warrants, vested options and all other
Convertible Company Securities in accordance with Section 6.3(j) hereto) issued
and outstanding immediately prior to the Effective Time (the "Outstanding
Company Common Stock") will be canceled and automatically converted into the
right to receive a ratable portion of Two Million Five Hundred Thousand Dollars
($2,500,000) (the "Cash Consideration") upon surrender of the certificates
representing such shares. At the Effective Time, all rights in respect of such
Outstanding Company Common Stock shall cease to exist, other than the right to
receive the Cash Consideration, and all such shares shall be cancelled and
retired.

               (b) Actions at the Effective Time. At the Effective Time:

                    (i)   Except for Dissenting Shares and the securities
referred to in Section 2.6(b)(ii) below, each share of Outstanding Company
Common Stock will automatically, by virtue of the Merger and without any action
on the part of the holder thereof, be canceled and converted into a right to
receive from Parent a portion of the Cash Consideration, in the amount as
determined pursuant to this Section 2.6.

                    (ii)  Each share of Company Common Stock held in the
treasury of the Company shall be canceled and retired without payment of any
consideration therefor.

                    (iii)  All unexercised options to purchase Company Common
Stock then outstanding under the Company's Employee Stock Option Plan and the

                    (iv)   Each outstanding share of common stock of Acquisition

               (c) Cash Consideration Escrow Holdback. At the Closing, Parent
shall withhold Two Hundred Fifty Thousand Dollars ($250,000) (the "Indemnity
Escrow Amount") from the Cash Consideration payable by Parent to the Company
Stockholders as a holdback for


                                       8
   14

any indemnity claims that Parent and/or the Parent Group and/or Acquisition Co.
may have hereunder. The Indemnity Escrow Amount shall be deposited in escrow for
a period of twelve (12) months following the Closing Date in accordance with the
terms and provisions hereof and an Escrow Agreement among Parent, the
Stockholder Representatives (as defined below) and Wells Fargo Bank, National
Association (the "Escrow Agent") in the form attached hereto as Exhibit D (the
"Escrow Agreement"). Any and all claims, actions, or losses that Parent and/or
the Parent Group and/or Acquisition Co. may have against the Company or the
Company Stockholders, in the aggregate, shall be limited to and payable only up
to the limit of the Indemnity Escrow Amount and Parent and or the Parent Group
and/or Acquisition Co. shall have no other recourse for any claims, actions or
losses, whatsoever, in excess thereof. The foregoing does not release the
officers and directors of the Company, individually, for any actions against
such officers and directors for fraud or intentional breach by the Company of
any representation, warranty or covenant made by the Company in this Agreement.

        2.7 DISSENTERS' RIGHTS. Any of the Outstanding Company Common Stock and
other capital stock that has not been voted for approval of this Agreement and
with respect to which a demand for payment and appraisal has been properly made
in accordance with the DGCL ("Dissenting Shares") will not be converted into the
right to receive the Cash Consideration otherwise payable with respect to such
Dissenting Shares at or after the Effective Time but will be converted into the
right to receive such consideration as may be determined to be due with respect
to such Dissenting Shares pursuant to the DGCL. If a holder of Dissenting Shares
("Dissenting Stockholder") withdraws his or her demand for such payment and
appraisal or becomes ineligible for such payment and appraisal, then, as of the
Effective Time or the occurrence of such event of withdrawal or ineligibility,
whichever last occurs, such holder's Dissenting Shares will cease to be
Dissenting Shares and will be converted into the right to receive, and will be
exchangeable for, the Cash Consideration into which such Dissenting Shares would
have been converted pursuant to Section 2.6 hereof. The Company will give Parent
and Acquisition Co. prompt notice of any demand received by the Company from a
holder of Dissenting Shares for appraisal of shares, and Parent shall have the
right to participate in, at its sole expense, all negotiations and proceedings
with respect to such demand. The Company agrees that, except with the prior
written consent of Parent and Acquisition Co., or as required under the DGCL, it
will not voluntarily make any payment with respect to, or settle or offer or
agree to settle, any such demand for appraisal. Each Dissenting Stockholder who,
pursuant to the provisions of the DGCL, becomes entitled to payment of the value
of the Dissenting Shares will receive payment therefor but only after the value
therefor has been agreed upon or finally determined pursuant to such provisions.
Any Cash Consideration that would have been issuable with respect to Dissenting
Shares will be retained by Parent.

        2.8 EXCHANGE PROCEDURE.

               (a) Promptly after the Effective Date, Parent shall cause
Computershare Trust Company, Inc. ("Exchange Agent") to mail to each holder of
record of a certificate or certificates which immediately prior to the Effective
Time represented shares of Outstanding Company Common Stock (the "Stock
Certificates") whose shares are being converted into the Cash Consideration
pursuant to Section 2.6 hereof (less any amount held in escrow pursuant to
Section 2.6(c) hereof), (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss of the Stock Certificates shall
pass, only upon delivery of the Stock Certificates to the Exchange Agent and
which shall be in such form and have such other provisions as Parent may


                                       9
   15

reasonably specify) (the "Letter of Transmittal") and (ii) instructions for use
in effecting the surrender of the Stock Certificates in exchange for the Cash
Consideration (less any amount held in escrow pursuant to Section 2.6(c)
hereof). Upon surrender of a Stock Certificate for cancellation to the Exchange
Agent or to such other agent or agents as may be appointed by Parent, together
with such letter of transmittal duly executed, the holder of such Stock
Certificate shall be entitled to receive in exchange therefor the Cash
Consideration (less any amount held in escrow pursuant to Section 2.6(c) hereof)
to which the holder of Outstanding Company Common Stock is entitled pursuant to
Section 2.6 hereof. The Stock Certificate so surrendered shall forthwith be
canceled. No interest will accrue or be paid to the holder of any Outstanding
Company Common Stock. From and after the Effective Date, until surrendered as
contemplated by this Section 2.8, each Stock Certificate shall be deemed for all
corporate purposes to evidence the amount of the Cash Consideration into which
the shares of Outstanding Company Common Stock represented by such Stock
Certificate have been converted.

               (b) The Cash Consideration delivered upon the surrender for
exchange of shares of Outstanding Company Common Stock in accordance with the
terms hereof shall be deemed to have been delivered in full satisfaction of all
rights pertaining to such Outstanding Company Common Stock. There shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of Outstanding Company Common Stock which were outstanding
immediately prior to the Effective Date. If, after the Effective Date, Stock
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Section 2.8.

               (c) In the event that any Stock Certificates evidencing shares of
Outstanding Company Common Stock shall have been lost, stolen or destroyed, the
Exchange Agent shall pay in exchange for such lost, stolen or destroyed Stock
Certificates, upon the making of an affidavit of that fact by the holder
thereof, such Cash Consideration as may be required pursuant to Section 2.6
hereof; provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Stock Certificates to deliver a bond in such sum as it may reasonably
direct as indemnity against any claim that may be made against Parent or the
Exchange Agent with respect to the Stock Certificates alleged to have been lost,
stolen or destroyed.

               (d) Notwithstanding anything to the contrary in this Section 2.8,
none of the Exchange Agent, the Surviving Corporation or any party hereto shall
be liable to a holder of shares of Outstanding Company Common Stock for any
amount properly paid to a public official pursuant to any applicable abandoned
property, escheat or similar law.

        2.9 ADDITIONAL ESCROW AND INDEMNITY PROVISIONS. By their approval of the
Merger, each of the Company Stockholders will be conclusively deemed to have
consented to and approved, as applicable: (i) the Escrow Agreement as to any
funds to which such Company Stockholder may be entitled from the Indemnity
Escrow Amount; (ii) the appointment of Stephen J. Sullivan and John K.A.
Prendergast as the representatives of the Company Stockholders, (the

   16

Agreement and under the Escrow Agreement. The Stockholder Representatives will
have authority and power to act on behalf of each Company Stockholder with
respect to the disposition, settlement or other handling of (a) indemnity claims
under Article VIII and (b) all claims governed by the Escrow Agreement, and all
rights or obligations arising under the Escrow Agreement so long as all Company
Stockholders are treated in a consistent manner in accordance with their
interests and/or consent in writing to different treatment. Each Company
Stockholder will be bound by all reasonable and lawful actions taken in good
faith by the Stockholder Representatives as to any funds to which such Company
Stockholder may be entitled from the Indemnity Escrow Amount in connection with
indemnity claims under Article VIII and the Escrow Agreement, and Parent will be
entitled to rely on any reasonable and lawful action or decision, taken or made
in good faith, of the Stockholder Representatives in connection therewith.
Except as to any funds to which such Company Stockholder may be entitled from
the Indemnity Escrow Amount for the settlement of claims under Article VIII or
the Escrow Agreement for an aggregate for all Company Stockholders of no more
than the Indemnity Escrow Amount, the Stockholder Representatives do not have
and will not have any authority to obligate the Company Stockholders' rights to
receive the "Merger Consideration" in any manner or for any circumstance, claim
or otherwise. The Stockholder Representatives do not have and will not have any
authority to enter into any agreement or agreements relating to claims under
Article VIII or the Escrow Agreement that would obligate the Company
Stockholders to pay any amount other than from the Indemnity Escrow Amount, or
an aggregate amount, together with amounts paid in settlement of all other such
claims, in excess of the Indemnity Escrow Amount. Any ultra vires act of the
Stockholder Representatives shall be null and void.

whether asserted or unasserted, whether absolute or contingent, whether accrued
or unaccrued, whether liquidated or unliquidated, and whether due or to become

incurred after December 31, 2000 in the Ordinary Course of Business which have
not had, and could not reasonably be expected to result in, individually or in
the aggregate, a Material Adverse Effect on the Company.

        3.12 TANGIBLE PERSONAL PROPERTY. The Company is in possession of and has
good and marketable title to, or has valid leasehold interests in or valid
rights under written agreements to use, all tangible personal property,
equipment, plants, buildings, structures, facilities and all other Assets and
Properties used in or reasonably necessary for the conduct of the Company's
business, including all tangible personal property reflected on the Company
Financial Statements and any tangible personal property acquired since December
31, 2000, other than property disposed of since such date in the Ordinary Course
of Business. All such tangible personal property, equipment, plants, buildings,
structures, facilities and all other Assets and Properties are listed in Section
3.12 of the Company Disclosure Schedule and are free and clear of all
Encumbrances, other than Permitted Encumbrances. All tangible personal property
and equipment used by the Company in its business as currently conducted are
structurally sound with no known material defects and are in good operating
condition and repair (subject to normal wear and tear) so as to permit the
operation of its business as presently conducted, no such equipment or tangible
personal property is in need of maintenance or repairs except for ordinary,
routine maintenance and repairs which are not material in nature or cost, and
with respect to each item of equipment and tangible personal property, the
Company has not received notification that it is in violation, in any material
respect, of any applicable building, zoning, subdivision, fire protection,
health or other law, Order, ordinance or regulation, and no such violation
exists.

        3.13 BENEFIT PLANS; ERISA.

               (a) Section 3.13(a) of the Company Disclosure Schedule lists each
Benefit Plan together with a brief description of the type of plan and benefit
provided thereunder. The Company has no commitment, proposal, or communication
to employees regarding the creation of an additional Benefit Plan or any
increase in benefits under any Benefit Plan. The Company has provided to Parent
(i) a copy of each Benefit Plan (including amendments) or, where substantially
similar arrangements exist, a sample copy and a list of persons participating in
such arrangement, (ii) the three (3) most recent annual reports on the Form 5500
series for each Benefit Plan required to file such report and (iii) the most
recent trustee's report for each Benefit Plan funded through a trust. For
purposes of this Section 3.13, the term "the Company" shall include any ERISA
Affiliate of the Company.

               (b) All Benefit Plans conform (and at all times have conformed)
in all material respects to, and are being administered and operated (and have
at all time been administered and


                                       18
   24

operated) in material compliance with, the requirements of ERISA, the Code and
all other applicable laws or governmental regulations. All returns, reports and
disclosure statements required to be made under ERISA and the Code with respect
to all Benefit Plans have been timely filed or delivered. There have not been
any "prohibited transactions," as such term is defined in Section 4975 of the
Code or Section 406 of ERISA involving any of the Benefit Plans that could
subject the Company to any material penalty or Tax imposed under the Code or
ERISA.

               (c) Each Qualified Plan has been determined by the Internal
Revenue Service to be so qualified or an application for such determination is
pending. Any such determination that has been obtained remains in effect and has
not been revoked, and with respect to any application that is pending, the
Company has no reason to suspect that such application for determination will be
denied. To the Company's Knowledge, nothing has occurred since the date of any
such determination that is reasonably likely to affect adversely such
qualification or exemption, or result in the imposition of excise Taxes or
income Taxes on unrelated business income under the Code or ERISA with respect
to any Benefit Plan.

               (d) The Company does not sponsor a defined benefit plan subject
to Title IV of ERISA, nor does it have a current or contingent obligation to
contribute to any multiemployer plan (as defined in Section 3(37) of ERISA). The
Company does not have any liability with respect to any employee benefit plan
(as defined in Section 3(3) of ERISA) other than with respect to the Benefit
Plans.

               (e) There are no pending or, to the Knowledge of the Company,
threatened claims by or on behalf of any Benefit Plans, or by or on behalf of
any individual participants or beneficiaries of any Benefit Plans, alleging any
breach of fiduciary duty on the part of the Company or any of its officers,
directors or employees under ERISA or any other applicable regulations, or
claiming benefit payments (other than those made in the ordinary operation of
such plans), nor is there, to the knowledge of the Company, any basis for such
claim. The Benefit Plans are not the subject of any pending (or to the knowledge
of the Company, any threatened) investigation or audit by the Internal Revenue
Service, the Department of Labor or the Pension Benefit Guaranty Corporation
("PBGC").

               (f) The Company has timely made all required contributions under
the Benefit Plans, including the payment of any premiums payable to the PBGC and
other insurance premiums.

               (g) With respect to any Benefit Plan that is an employee welfare
benefit plan (within the meaning of Section 3(1) of ERISA) (a "Welfare Plan"),
(i) each such Welfare Plan for which contributions are claimed by the Company as
deductions under any provision of the Code is in material compliance with all
applicable requirements pertaining to such deduction, (ii) with respect to any
welfare benefit fund (within the meaning of Section 419 of the Code) related to
such a Welfare Plan, there is no disqualified benefit (within the meaning of
Section 4976(b) of the Code) that would result in the imposition of a Tax under
Section 4976(a) of the Code, (iii) any Benefit Plan that is a group health plan
(within the meaning of Section 4980B(g)(2) of the Code) complies, and in each
and every case has complied, with all of the applicable material requirements of
Section 4980B of the Code, ERISA, Title XXII of the Public Health Service Act
and the Social Security Act, and (iv) all such Welfare Plans may be amended or
terminated at


                                       19
   25

any time on or after the Closing Date. No Benefit Plan provides any health, life
or other welfare coverage to employees of the Company beyond termination of
their employment with the Company by reason or retirement or otherwise, other
than coverage as may be required under Section 4980B of the Code or Part 6 of
ERISA, or under the continuation of coverage provisions of the laws of any state
or locality.

               (h) The consummation of the transactions contemplated by this
Agreement will not, either immediately or upon the occurrence of any event
thereafter, (i) entitle any current or former employee or officer or director of
the Company to severance pay, unemployment compensation or any other payment, or
(ii) accelerate the time of payment or increase the amount of compensation
otherwise due any such individual.

        3.14 REAL PROPERTY. The Company does not own any real property. Section
3.14 of the Company Disclosure Schedule contains a complete and accurate legal
description of each parcel of real property leased by the Company (as lessee or
lessor) (the "Real Property") and all Encumbrances (other than Permitted
Encumbrances) relating to or affecting the Real Property. The Company has a
valid leasehold interest in all real property used in or relating to the conduct
of the Company's business, free and clear of all Encumbrances other than
Permitted Encumbrances. The Company has rights of ingress and egress with
respect to such real property, and all buildings, structures, facilities,
fixtures and other improvements thereon that are material for the operation of
the Company's business. There is no pending, and to the Knowledge of the
Company, there is no contemplated or threatened condemnation of any of the
respective parcels of the Real Property or any part thereof. None of the Real
Property, or buildings, structures, facilities, fixtures or other improvements
thereon, or the use thereof, contravenes or violates any building, zoning, fire
protection, administrative, occupational safety and health or other applicable
law, rule, or regulation except for any contravention or violation which
individually or in the aggregate could not reasonably be expected to result in a
Material Adverse Effect on the Company. Each lease with respect to the Real
Property is a legal, valid and binding agreement of the Company subsisting in
full force and effect, and except as set forth in Section 3.14 of the Company
Disclosure Schedule, there is no, and the Company has not received notice of
any, default (or any condition or event which, after notice or lapse of time or
both, would constitute a default) thereunder. The leases in effect allow the
particular use of the premises involved, and no provision of any lease prohibits
or unduly limits the Company's ability to conduct its business so as to have a
Material Adverse Effect on the Company if enforced.

        3.15 INTELLECTUAL PROPERTY RIGHTS.

               (a) Generally. Section 3.15(a) of the Company Disclosure Schedule

States and foreign (1) Patents and Patent applications; (2) Trademark

                    (i)    All of the Company's Copyrights, if any, are
currently in compliance with all legal requirements, other than any requirement
that, if not satisfied, would not result in a cancellation of any registration

                    (ii)   None of the Company's registered Copyrights, if any,
has been within the last three (3) years or is now involved in any proceeding in
any court of law challenging the Company's rights in any such Copyright, and no
such action has been threatened in writing within the one (1)-year period prior
to the date of this Agreement.

                    (iii)  To the Knowledge of the Company, there has been no
prior use of any of the Company's Copyrights, if any, by any third party that
confers upon said third party superior rights in any such Copyright.

               (d) Patents.

                    (i)    All of the Company's Patents are currently in
compliance with legal requirements (including payment of filing, examination,
and maintenance fees and proofs of working or use), other than any requirement
that, if not satisfied, would not result in a revocation or lapse or otherwise
affect the enforceability of the Patent in question.

                    (ii)   None of the Company's Patents has been or is now
involved in any interference, reissue, reexamination or opposing proceeding in
the United States Patent and Trademark Office or any foreign patent office, and
no such action has been threatened in writing within the one (1)-year period
prior to the date of this Agreement, with the exception of the oppositions
identified in Section 3.15(d)(ii) of the Company Disclosure Schedule.


                                       21
   27

                    (iii)  To the Knowledge of the Company, there is no Patent
of any person that claims the same subject matter as any Patent of the Company
or invalidates any claim of any Patent of the Company.

               (e) Trade Secrets and Other Proprietary Information. Section
3.15(e) of the Company Disclosure Schedule sets forth a list of employees,
consultants, contractors and other entities who have executed proprietary
information and confidentiality agreements substantially in the Company's
standard forms and a list of employees, consultants, contractors and other
entities who have not executed such proprietary information and confidentiality
agreements. Except under confidentiality obligations, to the Knowledge of the
Company, there has been no disclosure by the Company of its confidential
information or Trade Secrets and Other Proprietary Information. The Company has

confidentiality agreements that have been entered into by its employees,
consultants, contractors and other entities.

Property Assets. To the Company's Knowledge, it owns or possesses adequate
licenses, re-marketing or sublicensing rights, or other rights to use, free and
clear of Encumbrances, Orders and arbitration awards, all of the Intellectual
Property used in its business. The Intellectual Property identified in Section
3.15(a) of the Company Disclosure Schedule, together with the Company's Trade
Secrets and Other Proprietary Information and the Company's unregistered
Copyrights and rights granted to the Company under the Inbound License
Agreements, constitute all the Intellectual Property rights and Inbound License
Agreements used in the operation of the Company's business as it is currently
conducted and to the Knowledge of the Company are all such Intellectual Property
rights and Inbound License Agreements necessary to operate such business after
the Effective Time in substantially the same manner as such business has been
operated by the Company prior thereto.

               (h) No Infringement by the Company. To the knowledge of the
Company, the products used, manufactured, marketed, sold or licensed by the
Company, and all Intellectual Property used in the conduct of the Company's
business as currently conducted, do not infringe upon, violate or constitute the
unauthorized use of any rights owned or controlled by any third party, including
any Intellectual Property of any third party.

   28

               (i) No Pending or Threatened Infringement Claims. No litigation

Company, (1) alleging that the Company has engaged in any activity or conduct
that infringes upon, violates or constitutes the unauthorized use of the
Intellectual Property rights of any third party or (2) challenging the
ownership, use, validity or enforceability of any Intellectual Property owned or
exclusively licensed by or to the Company. No Intellectual Property that is
owned or licensed by the Company is subject to any outstanding Order,

stockholders, other than liability for any pre-termination breach; provided,
that the following provisions shall survive any termination: Section 7.2 and
Sections 5.6, 5.7, 7.4, 9.9, 9.10, 9.11 and 9.12.

        7.3 AMENDMENT. This Agreement may be amended by action taken by the
Company, Parent and Acquisition Co. at any time before or after approval of the
Merger by the stockholders of the Company but after any such approval no
amendment shall be made that requires the approval of such stockholders under
applicable law without such approval. This Agreement (including the Company
Disclosure Schedule) may be amended only by an instrument in writing signed on
behalf of the parties hereto.

        7.4 BREAK-UP FEE. In the event (i) the Company breaches its obligations
under Section 5.4 above, (ii) Parent terminates this Agreement pursuant to
Section 7.1(d) above, or (iii) Parent terminates this Agreement due to the
failure of the condition set forth in Section 2.10(b)(viii), the Company shall
grant to Parent a non-exclusive, royalty-free license to the Company's Gene
Expression Profiling Technology Patents (as defined below) in the form of
Exhibit L attached hereto (the "License Agreement"). The License Agreement shall
be deemed to be in full force and effect immediately upon the occurrence of (i),
(ii) or (iii) above even if not then executed by the parties. The parties
acknowledge and agree that it is difficult or impossible to determine with
precision the amount of damages that would or might be incurred by Parent in the
event of (i), (ii) or (iii) above. It is understood and agreed by the parties
that in the event of (i), (ii) or (iii) above, (A) it would be impracticable or
extremely difficult to fix the actual damages resulting therefrom, (B) the
granting of the license under the License Agreement is in the nature of
liquidated damages, and not a penalty, and is fair and reasonable, and (C) the
fair market value of the license granted pursuant to the License Agreement
represents a reasonable estimate of fair compensation for the losses that may
reasonably be anticipated by Parent upon the occurrence of (i), (ii) or (iii)
above, and shall be the sole and exclusive measure of damages in any such event.
Upon the effectiveness of the License Agreement in accordance with the
provisions of this Section 7.4, the Company shall be relieved of any further
liability in respect of damages relating to the fact or circumstance giving rise
to such liquidated damages. "Gene Expression Profiling Technology Patents" shall
mean (1) United States patent numbers 5,585,232 (issued December 17, 1996),
5,589,337 (issued December 31, 1996) and 5,811,231 (issued September 22, 1998)
and divisional patent application 09/074,938 (filed May 8, 1998), (2) all
inventions described and/or claimed therein, (3) all substitutions, divisions,
continuations, continuations-in-part, reissues or reexaminations thereof and
patents issuing thereon, and (4) all foreign patents and patent applications
corresponding thereto.

        7.5 EXTENSION; WAIVER. At any time prior to the Effective Time, each
party hereto may, only by action taken in writing, (i) extend the time for the
performance of any of the obligations or other acts of the other party, (ii)
waive any inaccuracies in the representations and warranties of the other party
contained herein or in any document certificate or writing delivered pursuant
hereto or (iii) waive compliance by the other party with any of the agreements
or conditions contained herein. Any agreement on the part of any 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. The failure of any party hereto to
assert any of its rights hereunder shall not constitute a waiver of such rights.

                                  ARTICLE VIII

                    ACTIONS BY THE PARTIES AFTER THE CLOSING

        8.1 SURVIVAL OF REPRESENTATIONS, WARRANTIES, ETC. The representations,
warranties and covenants contained in or made pursuant to this Agreement or any
certificate, document or instrument delivered pursuant to or in connection with
this Agreement in the transactions contemplated hereby shall survive the
execution and delivery of this Agreement and the Closing hereunder
(notwithstanding any investigation, analysis or evaluation by any party hereto
or their designees of the Assets and Properties, business, operations or
condition (financial or otherwise) of the other party), and thereafter the
representations and warranties the parties herein shall continue to survive in
full force and effect for a period of twelve (12) months after the Closing Date.

        8.2 INDEMNIFICATION.

               (a) Out of the Indemnity Escrow Amount. Subject to Section 8.2(e)
below, the Parent, the Surviving Corporation and their respective officers,
directors, employees, affiliates, agents, successors, subsidiaries and assigns
(collectively the "Parent Group") shall be indemnified, defended and held
harmless out and to the extent of the Indemnity Escrow Amount from and against
any and all costs, losses (including, without limitation, diminution in value),
liabilities, damages, lawsuits, deficiencies, claims and expenses, including
without limitation, interest, penalties, costs of mitigation, lost profits,
losses resulting from any shutdown or curtailment of operations, attorneys' fees
and all amounts paid in investigation, defense or settlement of any of the
foregoing (collectively, the "Damages"), incurred in connection with, arising
out of, resulting from or incident to any breach of any covenant,
representation, warranty or agreement or the inaccuracy of any representation,
made by the Company in or pursuant to this Agreement, or in the other documents
delivered to Parent or Acquisition Co. in connection with the transactions
contemplated in this Agreement.

               (b) By Parent. Parent and Acquisition Co. shall, jointly and
severally, indemnify, defend and hold harmless the Company Stockholders and
their respective officers, employees, agents, successors and assigns from and
against any and all Damages incurred in connection with, arising out of,
resulting from or incident to any breach of any covenant, representation,
warranty or agreement or the inaccuracy of any representation, made by Parent in
or pursuant to this Agreement, or in any other documents delivered to the
Company or to any Company Stockholder in his capacity as a Company Stockholder
in connection with the transactions contemplated in this Agreement.

               (c) Third Party Claims; Defense of Claims. If any Action or
Proceeding is filed or initiated against any party entitled to the benefit of
indemnity hereunder, written notice thereof shall be given to the indemnifying
party (or if the indemnification is out of the Indemnity Escrow Amount, the
Stockholder Representatives) as promptly as practicable (and in any event within
ten (10) days after the service of the citation or summons); provided, however,
that the failure of any indemnified party to give timely notice shall not affect
rights to indemnification and defense hereunder except to the extent that the
indemnifying party demonstrates actual damage caused by such failure. After such
notice, if the indemnifying party (or the Stockholder Representatives, as
applicable) shall acknowledge in writing to the indemnified party that the
indemnifying party


                                       42
   48

shall be obligated under the terms of its indemnity hereunder in connection with
such Action or Proceeding, then the indemnifying party (or the Stockholder
Representatives, as applicable) shall be entitled, if it so elects, to take
control of the defense and investigation of such Action or Proceeding and to
employ and engage attorneys of its own choice to handle and defend the same,
such attorneys to be reasonably satisfactory to the indemnified party, at the
indemnifying party's (or the Indemnity Escrow Amount's, as applicable) cost,
risk and expense (unless (i) the indemnifying party (or the Stockholder
Representatives, as applicable) has failed to assume the defense of such Action
or Proceeding or (ii) the named parties to such Action or Proceeding include
both of the indemnifying party and the indemnified party, and the indemnified
party (or the Stockholder Representatives, as applicable) and its counsel
determine in good faith that there may be one or more legal defenses available
to such indemnified party that are different from or additional to those
available to the indemnifying party and that joint representation would be
inappropriate), and to compromise or settle such Action or Proceeding, which
compromise or settlement shall be made only with the written consent of the
indemnified party (or the Stockholder Representatives, as applicable), such
consent not to be unreasonably withheld. The indemnified party (or the
Stockholder Representatives, as applicable) may withhold such consent if such
compromise or settlement would adversely affect the conduct of business or
requires less than an unconditional release to be obtained. If (i) the
indemnifying party (or the Stockholder Representatives, as applicable) fails to
assume the defense of such Action or Proceeding within fifteen (15) days after
receipt of notice thereof pursuant to this Section 8.2, or (ii) the named
parties to such Action or Proceeding include both the indemnifying party and the
indemnified party and the indemnified party (or the Stockholder Representatives,
as applicable) and its counsel determine in good faith that there may be one or
more legal defenses available to such indemnified party that are different from
or additional to those available to the indemnifying party and that joint
representation would be inappropriate, the indemnified party against which such
Action or Proceeding has been filed or initiated (or the Stockholder
Representatives, as applicable) will (upon delivering notice to such effect to
the indemnifying party or the Stockholder Representatives, as applicable) have
the right to undertake, at the indemnifying party's (or the Indemnity Escrow
Amount's, as applicable) cost and expense, the defense, compromise or settlement
of such Action or Proceeding on behalf of and for the account and risk of the
indemnifying party (or the Indemnity Escrow Amount, as applicable); provided,
however, that such Action or Proceeding shall not be compromised or settled
without the written consent of the indemnifying party (or the Stockholder
Representatives, as applicable), which consent shall not be unreasonably
withheld. In the event the indemnified party (or the Stockholder
Representatives, as applicable) assumes defense of the Action or Proceeding, the
indemnified party (or the Stockholder Representatives, as applicable) will keep
the indemnifying party (or the Stockholder Representatives, as applicable)
reasonably informed of the progress of any such defense, compromise or
settlement and will consult with, when appropriate, and consider any reasonable
advice from, the indemnifying party (or the Stockholder Representatives, as
applicable) with respect to any such defense, compromise or settlement. The
indemnifying party (or the Indemnity Escrow Amount, as applicable) shall be
liable for any settlement of any action effected pursuant to and in accordance
with this Section 8.2 and for any final judgment (subject to any right of
appeal), and the indemnifying party agrees to indemnify and hold harmless the
indemnified party (or the indemnified party shall be indemnified and held
harmless out and to the extent of the Indemnity Escrow Amount, as applicable)
from and against any Damages by reason of such settlement or judgment.


                                       43
   49

        Regardless of whether the indemnifying party (or the Stockholder
Representatives, as applicable) or the indemnified party (or the Stockholder
Representatives, as applicable) takes up the defense, the indemnifying party
will pay (or out and to the extent of the Indemnity Escrow Amount shall be paid,
as applicable) reasonable costs and expenses in connection with the defense,
compromise or settlement for any Action or Proceeding under this Section 8.2.

        The indemnified party (or the Stockholder Representatives, as
applicable) shall cooperate in all reasonable respects with the indemnifying
party (or the Stockholder Representatives, as applicable) and its attorneys in
the investigation, trial and defense of such Action or Proceeding and any appeal
arising therefrom; provided, however, that the indemnified party (or the
Stockholder Representatives, as applicable) may, at its own cost (or the cost of
the Indemnity Escrow Amount, as applicable), participate in the investigation,
trial and defense of such Action or Proceeding and any appeal arising therefrom.
The indemnifying party shall pay (or out and to the extent of the Indemnity
Escrow Amount shall be paid, as applicable) all expenses due under this Section
8.2 as such expenses become due. In the event such expenses are not so paid, the
indemnified party (or the Stockholder Representatives, as applicable) shall be
entitled to settle any Action or Proceeding under this Section 8.2 without the
consent of the indemnifying party (or the Stockholder Representatives, as
applicable) and without waiving any rights the indemnified party may have
against the indemnifying party.

               (d) Indemnity Claims. A claim for indemnification for any matter
not involving a third-party claim may be asserted by notice to the party from
whom indemnification is sought (or the Stockholder Representatives, as
applicable) pursuant to the terms and conditions set forth in the Escrow
Agreement.

               (e) Limitation on Indemnification.

                    (i)    The Company Stockholders shall not be entitled to
indemnification from Parent, and Parent, Acquisition Co. and no member of the
Parent Group shall be entitled to indemnification out of the Indemnity Escrow
Amount, for amounts payable pursuant to the indemnification obligations in this
Section 8.2 until the total of all such Damages incurred by the indemnified
party exceed Fifty Thousand Dollars ($50,000) in the aggregate (the "Threshold
Amount"), in which case the indemnified party shall be entitled to
indemnification from the indemnifying party for all Damages due hereunder
including the Threshold Amount;

                    (ii)   Except for actions by Parent and/or any member of the
Parent Group and/or Acquisition Co. against the officers and directors of the
Company for any fraud or intentional breach by the Company or its officers and
directors, from and after the Effective Time, the indemnification provisions of
Section 8.2 shall be the exclusive remedy for Parent and/or any member of the
Parent Group and/or Acquisition Co. for a breach of any representation, warranty
or covenant by the Company in this Agreement and shall be in lieu of any rights
Parent and/or any member of the Parent Group and/or Acquisition Co. may have
under law or in equity with respect to any such breaches or otherwise. Any and
all claims, actions, or losses that Parent and/or the Parent Group and/or
Acquisition Co. may have against the Company or the Company Stockholders, in the
aggregate, shall be limited to and payable only up to the limit of the Indemnity
Escrow Amount and Parent and/or the Parent Group and/or Acquisition Co. shall
have no other recourse for any claims, actions or losses, whatsoever, in excess
thereof. The foregoing does not release the officers and directors of the
Company,


                                       44
   50

individually, for any actions against such officers and directors for fraud or
intentional breach by the Company of any representation, warranty or covenant
made by the Company in this Agreement.

                    (iii) Upon making any payments to Parent and/or any member
of the Parent Group and/or Acquisition Co. for any indemnification claim
pursuant to Section 8.2, the Company Stockholders shall be subrogated, to the
extent of such payment to Parent and/or any member of the Parent Group and/or
Acquisition Co., to any rights the Company may have against third parties with
respect to the subject matter underlying such indemnification claim.

        8.3 INDEMNITY ESCROW ACCOUNT. The Indemnity Escrow Amount shall be
maintained in the escrow account established pursuant to the Escrow Agreement
until the date which is twelve (12) months following the Closing Date (the
"Escrow Period") for the purpose of satisfying claims by Parent and/or any
member of the Parent Group and/or Acquisition Co. for indemnification under this
Article VIII. Upon expiration of the Escrow Period, and subject to the terms of
this Section 8.3 and the Escrow Agreement, the Escrow Agent shall deliver or
cause to be delivered to the Company Stockholders the balance, if any, remaining
in the escrow account. If, upon expiration of the Escrow Period, Parent and/or
any member of the Parent Group and/or Acquisition Co. shall have asserted a
claim for indemnity in accordance with this Article VIII and such claim is
pending or unresolved at the time of such expiration, the Escrow Agent shall
retain in escrow an amount of cash equal to the value of the asserted claim
until such matter is resolved.

        8.4 FURTHER ASSURANCES. In case at any time after the Closing any
further action is necessary or desirable to carry out the purposes of this
Agreement, each of the parties will take such further action (including the
execution and delivery of such further instruments and documents) as the other
party reasonably may request, all the sole cost and expense of the requesting
party (unless the requesting party is entitled to indemnification therefor under
this Article VIII).

supersede all prior and contemporaneous commitments, discussions and agreements
among the parties with respect to the subject matter hereof and contain the sole
and entire agreement among the parties hereto with respect thereto.

        9.3 WAIVER. Any term or condition of this Agreement may be waived at any
time by the party that is entitled to the benefit thereof, but no such waiver
shall be effective unless set forth in a written instrument duly executed by or
on behalf of the party waiving such term or condition. No waiver by any party
hereto of any term or condition of this Agreement, in any one or more instances,
shall be deemed to be or construed as a waiver of the same or any other term or
condition of this Agreement on any future occasion. All remedies, either under
this Agreement or by law or otherwise afforded, will be cumulative and not
alternative.

        9.4 AMENDMENT. This Agreement may be amended, supplemented or modified
only by a written instrument duly executed by or on behalf of each party hereto.

        9.5 NO THIRD PARTY BENEFICIARY. The terms and provisions of this
Agreement are intended solely for the benefit of each party hereto and their
respective successors or permitted assigns, and it is not the intention of the
parties to confer third-party beneficiary rights upon any other Person other
than any Person entitled to indemnity or defense under Article VIII.

        9.6 NO ASSIGNMENT; BINDING EFFECT. Neither this Agreement nor any right,
interest or obligation hereunder may be assigned by any party hereto without the
prior written consent of the other parties hereto and any attempt to do so will
be void, except that any party's rights to indemnification under Article VIII
may be freely assigned. This Agreement is binding upon, inures to the benefit of
and is enforceable by the parties hereto and their respective permitted
successors and assigns.

        9.7 HEADINGS. The headings used in this Agreement have been inserted for
convenience of reference only and do not define or limit the provisions hereof.

        9.8 SEVERABILITY. If any provision of this Agreement is held to be
illegal, invalid or unenforceable under any present or future law, and if the
rights or obligations of any party hereto under this Agreement will not be
materially and adversely affected thereby, (i) such provision will be fully
severable, (ii) this Agreement will be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof,
(iii) the remaining provisions of this Agreement will remain in full force and
effect and will not be affected by the illegal, invalid or unenforceable
provision or by its severance herefrom and (iv) in lieu of such illegal, invalid
or unenforceable provision, there will be added automatically as a part of this
Agreement a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible and mutually
acceptable to the parties herein.

        9.9 GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of California applicable to contracts
executed and performed in such State, without giving effect to conflicts of laws
principles.

        9.10 ARBITRATION AND VENUE. Any controversy or claim arising out of or
relating to this Agreement or the making, performance or interpretation thereof
shall be submitted to


                                       47
   53

arbitration in San Diego, California, pursuant to the rules and procedures of
the commercial arbitration rules of the American Arbitration Association before
a panel of three arbitrators. The ruling of the arbitrator shall be final, and
judgment thereon may be entered in any court having jurisdiction. If any
question is submitted to a court of law for resolution, then the Superior Court
of the County of San Diego or the United States District Court having
jurisdiction in the County of San Diego shall be the exclusive court of
competent jurisdiction for the resolution of such question. Each party will bear
one half of the cost of the arbitration filing and hearing fees, and the cost of
the arbitrator. Each party will bear its own attorneys' fees, unless otherwise
decided by the arbitrator. The parties understand and agree that the arbitration
shall be instead of any civil litigation and that the arbitrator's decision
shall be final and binding to the fullest extent permitted by law and
enforceable by any court having jurisdiction thereof. Each party shall be
entitled to pre-hearing discovery as provided in California Code of Civil
Procedure Section 1283.05.

        9.11 CONSTRUCTION. No provision of this Agreement shall be construed in
favor of or against any party on the ground that such party or its counsel
drafted the provision. Any remedies provided for herein are not exclusive of any
other lawful remedies which may be available to either party. This Agreement
shall at all times be construed so as to carry out the purposes stated herein.

        9.12 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by facsimile, each of which will be deemed an original, but all
of which together will constitute one and the same instrument.
