the Certificate surrendered, or established to the satisfaction of Acquiror or
any agent designated by it that such tax has been paid or is not payable.

          ---------------------------------------------------

Company's Intellectual Property, nor is the Company bound by or a party to any

administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of the Company, or that would conflict with the
Company's business.  The Company is not aware of any violation or infringement
by a third party of any of the Company's Intellectual Property.  Neither the

conditions, or provisions of, or constitute a default under, any contract,
covenant, or instrument under which any of such employees is now obligated.  The

is obligated under any contract (including licenses, covenants, or commitments

of Acquiror's Intellectual Property. Neither the execution nor delivery of this
Agreement or any of the Related Agreements, nor the carrying on of Acquiror's
business by the employees of Acquiror, nor the conduct of Acquiror's business
will conflict with or result in a material breach of the terms, conditions, or
provisions of, or constitute a default under, any contract, covenant, or
instrument under which any of such employees is now obligated. Acquiror has no
plan to, and does not believe it is or will be necessary to utilize any

Schedule 3.11; provided, that (x) ownership of no more than one percent (1%) of
the outstanding voting stock of a publicly traded corporation and no more than
ten percent (10%) of the outstanding equity of any other entity shall not be
deemed an "economic interest in any entity" for purposes of this Section 3.12

           --------------------
with, is not in material violation of, and has not received any notices of

           ---------

any employment contract, patent disclosure agreement or any other contract or
agreement relating to the right of any such employee to be employed by Acquiror
because of the nature of the business conducted or to be conducted by Acquiror
or for any other reason, and the continued employment by Acquiror of its present
employees will not result in any such violations. Except as set forth on

services for Acquiror has executed an employee inventions and proprietary rights
assignment and confidentiality agreement with Acquiror, the form of which has
been made available to the Company. Acquiror has complied in all material
respects with all applicable state and federal equal employment opportunity and
other laws related to employment. To the best of Acquiror's knowledge after
reasonable investigation, no employee of Acquiror is in material violation of
any term of any employment contract, patent disclosure agreement or any other
contract or agreement relating to the right of any such employee to be employed
by Acquiror because of the nature of the business conducted or to be conducted
by

                                     -27-

Acquiror or for any other reason, and the continued employment by Acquiror of
its present employees will not result in any such violations. Acquiror is not
aware that any officer or key employee, or that any group of key employees,
intends to terminate his or their employment with Acquiror, nor does Acquiror
have a present intention to terminate the employment of any of the foregoing.

employment of each officer and employee of Acquiror is terminable at the will of
Acquiror.

Acquiror's knowledge, there is no investigation pending or threatened against
Acquiror, its properties or any of its officers or directors, in their
respective capacities as such, by or before any governmental entity. Schedule

proceeding or investigation, the forum, the parties thereto, the subject matter
thereof and the amount of damages claimed or other remedy requested. No

Acquiror to manufacture, offer or sell any of its products or services in the
present manner or style thereof.

take promptly, or cause to be taken, all actions, and to do promptly, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated
hereby to obtain all necessary waivers, consents and approvals and to effect all

securing to the parties hereto the benefits contemplated by this Agreement;
provided that Acquiror shall not be required to agree to any divestiture by
Acquiror or the Company or any of Acquiror's subsidiaries or affiliates of
shares of capital stock or of any

                                     -29-
<PAGE>

business, assets or property of Acquiror or its subsidiaries or affiliates or
the Company or its affiliates, or the imposition of any material limitation on
the ability of any of them to conduct their businesses or to own or exercise
control of such assets, properties and capital stock.

     5.8  Notification of Certain Matters.  The Company shall give prompt notice
          -------------------------------
to Acquiror, and Acquiror shall give prompt notice to the Company, of (i) the
occurrence or non-occurrence of any event, the occurrence or non-occurrence of
which is likely to cause any representation or warranty of the Company and
Acquiror, respectively, contained in this Agreement to be untrue or inaccurate
at or prior to the Effective Time except as contemplated by this Agreement
(including the Company Schedules) and (ii) any failure of the Company or
Acquiror, as the case may be, to comply with or satisfy in any material respect
any covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
Section 5.8 shall not limit or otherwise affect any remedies available to the

shall be eligible for employee benefits generally available to employees of
Acquiror to the same extent as all other employees of Acquiror and (ii) Acquiror
shall grant all continuing employees of the Company credit for service (to the
same extent as service with Acquiror or any subsidiary of Acquiror is taken into
account with respect to similarly situated employees of Acquiror and its
subsidiaries) with the Company for determining benefit levels under such
employee benefits. Except for the stock option grants set forth in Schedule
5.10, which Acquiror has agreed to grant, nothing contained in this Agreement
shall create or imply any obligation on the part of Acquiror, the Company or the
Surviving Corporation to provide any continuing employment right to any
individual.

     5.11 Stock Options.
          -------------

          (a)  At the Effective Time, each Company Stock Option, whether or not
exercisable, will be assumed by Acquiror and, as of the Effective Time, Acquiror
hereby assumes such Company Stock Options in accordance with the terms of this
Section 5.11. Each Company Stock Option so assumed by Acquiror under this
Agreement will continue to have, and be subject to, the same terms and
conditions set forth in the applicable Company Stock Option Plan immediately
prior to the Effective Time, except that (i) each Company Stock Option will be
exercisable (or will become exercisable in accordance with its terms) for that
number of whole shares of Acquiror Common Stock equal to the product of the
number of shares of Company Common Stock that were issuable upon exercise of
such Company Stock Option immediately prior to the Effective Time times (y) the
Exchange Ratio, rounded down to the nearest whole share of Acquiror Common Stock
and (ii) the per share exercise price for the Acquiror Common Stock issuable
upon exercise of such

                                     -30-
<PAGE>

assumed Company Stock Option will be equal to the quotient determined by
dividing (x) the exercise price per share of Company Common Stock at which such
Company Stock Option was exercisable immediately prior to the Effective Time by
(y) the Exchange Ratio, rounded up to the nearest whole cent. As soon as
reasonably practicable after the Effective Time (and in any event within 5 days
after the Effective Time), Acquiror will issue to each holder of an outstanding
Company Stock Option a notice describing the foregoing assumption of such
Company Stock Option by Acquiror.


          (b)  It is intended that, subject to Section 5.11(a) and to the extent
permitted by applicable law, the Company Stock Options assumed by Acquiror shall
qualify following the Effective Time as incentive stock options as defined in
Section 422 of the Code to the extent Company Stock Options qualified as
incentive stock options immediately prior to the Effective Time and the
provisions of this Section 5.11 shall be applied consistent with such intent.

     5.12 Third Party Consents.  As soon as practicable after the date hereof,

obtain any material consents, waivers and approvals required to be obtained in

expenses of preparing any such Tax Returns of the Company pursuant to this
Section 5.13(a) and the amount of the Taxes shown on such Tax Returns of the
Company; provided, however, that the amount reimbursed for Taxes shall not
exceed $30,000. Such Tax Returns will be prepared and filed in accordance with
applicable law and in a manner consistent with past practices and shall be
subject to review and consent by Acquiror, which consent will not be
unreasonably withheld.

          (b)  The Shareholders shall provide Acquiror with a copy of all Tax
Returns filed pursuant to Section 5.13(a) with respect to the Pre-Closing
Periods. From and after the Effective Date, Acquiror and the Company, on the one
hand, and the Shareholders, on the other hand, shall make available to the
other, as reasonably requested, all information, records or documents relating
to the Tax liabilities of the Company for all periods ending on or prior to the
Effective Date, and will preserve such information, records or documents until
the expiration of any applicable statute of limitations or extensions thereof.

financial statements. Quarterly financial statements will be provided within
forty-five (45) days after each quarterly period (other than the fourth quarter)
and the annual financial statements will be provided within ninety (90) days
after the end of the fiscal year. Acquiror's obligation to provide the foregoing

pursuant to a registration statement declared effective by the Securities and
Exchange Commission or (b) upon any merger or consolidation of Acquiror with any

                  SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                            INDEMNIFICATION; ESCROW

     7.1  Survival of Representations and Warranties.  All of the Company's and
          ------------------------------------------
Acquiror's representations and warranties in this Agreement or in any instrument
delivered pursuant to this Agreement (each as modified by the Company Schedules)
shall survive the Merger and continue until 5:00 p.m., California time, on the
date which is one year following the Closing Date (the "Expiration Date");
                                                        ---------------
provided, however, that the representations and warranties in Section 2.9 and
the indemnification provisions in Section 5.13 shall survive until the lapsing
of the applicable statute of limitations period.

     7.2  Obligation of the Company to Indemnify, Reimburse, etc.  Subject to
          ------------------------------------------------------
the provisions of Sections 7.4 and 8.2 hereof, the Shareholders severally (in
accordance with their proportionate stock interest of Acquiror Common Stock
received by the Stockholders pursuant to the Merger), shall indemnify,
reimburse, defend and hold harmless Acquiror and its successors and assigns and
each of its directors, officers, employees, affiliates, and its respective
successors and assigns (each a "Acquiror Indemnitee") from and against all
                                -------------------
Losses resulting from, imposed upon, incurred or suffered by any of them,
directly or indirectly, based upon, arising out of or otherwise in respect of
any inaccuracy in or any breach of any representation, warranty, covenant or
agreement of the Company; provided that no claim for indemnification may be made
by any Acquiror Indemnitee pursuant to this Section 7.2 at any time following
the Expiration Date; provided, however, that the

                                     -35-
<PAGE>

foregoing limitations to indemnification shall not apply to any claims that
result from a breach of Sections 2.9 or 5.13. With respect to claims for
indemnification that result from a breach of Sections 2.9 or 5.13, Acquiror
Indemnitees shall be entitled to recover all Losses incurred as a result of such
breach until the lapsing of the applicable statute of limitations period. For
purposes of this Agreement, "Losses" shall mean any claims, losses, liabilities,
                             ------
damages, causes of action, costs and expenses (including reasonable attorney's,
accountant's, consultant's and expert's fees and expenses), net of any insurance
proceeds, to which the indemnified party is entitled by virtue of such claims,
losses, liabilities, damages, causes of action, costs and expenses.

     7.3  Obligation of Acquiror to Indemnify, Reimburse, etc.  Subject to the
          ---------------------------------------------------
provisions of Sections 7.4 and 8.2 hereof, Acquiror and its respective
successors and assigns, jointly and severally, shall indemnify, defend and hold
harmless the Company and its successors and assigns and each of its directors,
officers, employees, affiliates, and their respective successors and assigns
(each a "Company Indemnitee") from and against any Losses resulting from,
         ------------------
imposed upon, incurred or suffered by any of them, directly or indirectly, based
upon, arising out of or otherwise in respect of any inaccuracy in or breach of
any representation, warranty, covenant or agreement of Acquiror; provided that
no claim for indemnification may be made by any Company Indemnitee pursuant to
this Section 7.3 at any time following the Expiration Date.

     7.4  Limits on Indemnification, Reimbursement, etc.  No Acquiror Indemnitee
          ----------------------------------------------
and no Company Indemnitee shall have any right to seek indemnification,
reimbursement or defense under this Agreement or the Escrow Agreement until
Losses which would otherwise be indemnifiable hereunder, and have been incurred
by such party and other indemnitees associated with or related to such party,
exceed $25,000 (at which point such party to be indemnified shall be entitled to
recover indemnification for all Losses). In the event that any claim for
indemnification, reimbursement or defense is made by Acquiror pursuant to this
Section, the amount of any Losses shall be satisfied out of the Escrow Fund (as
defined below); provided, however, that if the amount of the Losses exceeds the
Escrow Fund, the Losses will be settled by the Shareholders (with the form of
the consideration to be at the election of the Shareholders), either by paying
cash or surrendering that number of shares of Acquiror Common Stock whose value
equal the amount of the claim, using the fair market value of a share of
Acquiror Common Stock on the date that any written claim for indemnification is
made. For purposes of the foregoing, (a) if the Common Stock is not publicly
traded, the fair market value will be the higher of (i) the price at which
Acquiror's Board of Directors at such time has determined is the fair market
value of Acquiror's Common Stock for purposes of stock option grants and (ii)
the price used for the Company's most recent arms' length third party
transaction or (b) if the Common Stock is publicly traded, the fair market value
will be the closing sales price on the last trading day prior to the date that
the written claim for indemnification is made. Notwithstanding the foregoing,
absent fraud of any party (for which there shall be no limitation of liability),
no party shall be entitled to seek indemnification, reimbursement or defense for
an amount which would require the Shareholders to surrender more than an
aggregate of 40% of the shares issued to the Shareholders pursuant to the merger
(or not more than 641,487 shares of Acquiror Common Stock, as adjusted for stock
splits, stock dividends, recapitalizations and the like), calculated based on
the assumption that all Shareholders elect to surrender shares to satisfy all
indemnification claims.

                                     -36-
<PAGE>

     7.5  Escrow Arrangements.  Concurrent with the Effective Time, the Escrow
          -------------------
Amount shall be placed in an escrow fund (the "Escrow Fund"), to be governed by
                                               -----------
the terms of the Escrow Agreement. The Escrow Fund shall be available to
compensate Acquiror and its affiliates for losses incurred by Acquiror and its
affiliates in connection with breaches of representations, warranties, or
covenants contained herein or delivered pursuant hereto. The terms and
conditions of the Escrow Fund shall be set forth more fully in the Escrow
Agreement. The Escrow Fund shall terminate at the Expiration Date. Donald Joseph
Edgerton and Paul Geczik have been selected and authorized by the Company's
shareholders to act as their representatives (the "Representatives") in regard
to the Escrow Fund.

     7.6  Claims for Indemnification.  Whenever any claim shall arise for
          --------------------------
indemnification under this Section 7, and such claim is not made against the
Escrow Fund, Acquiror or the Company, as the case may be, seeking
indemnification (the "Indemnified Party"), shall promptly notify (the "Claim
                      -----------------                                -----
Notice") the party for whom indemnification is sought hereunder (the
------
"Indemnifying Party") of the claim and, when known, the facts constituting the
 ------------------
basis for such claim. In the event of any such claim for indemnification
hereunder resulting from or in connection with any claim or legal proceedings by
a third party (each, a "Proceeding"), the Claim Notice shall set forth in
                        ----------
reasonable detail the nature thereof and the basis upon which such Indemnified
Party seeks indemnification hereunder; provided, however, that the failure of
                                       --------  -------
any Indemnified Party to give such notice shall not relieve the Indemnifying
Party of its obligations under such Section, except to the extent that the
Indemnifying Party is actually prejudiced by the failure to give such notice.

          (b)  In the case of any such Proceeding by a third party against an
Indemnified Party, the Indemnifying Party shall, upon notice as provided above,
assume the defense thereof, with counsel reasonably satisfactory to the
Indemnified Party, and, after prompt notice (and, in any event, within twenty
(20) days from receipt of written notice of such Proceeding in accordance with
Section 7.6(a)) from the Indemnifying Party to the Indemnified Party of its
assumption of the defense thereof, the Indemnifying Party shall not be liable to
such Indemnified Party for any legal or other expenses subsequently incurred by
the Indemnified Party in connection with the defense thereof (but the
Indemnified Party shall have the right, but not the obligation, to participate
at its own cost and expense in such defense by counsel of its own choice) or for
any amounts paid or foregone by the Indemnified Party as a result of the
settlement or compromise thereof (without the written consent of the
Indemnifying Party).

          (c)  Anything in Section 7.6(b) notwithstanding, if both the
Indemnifying Party and the Indemnified Party are named as parties or subject to
such Proceeding and either such party determines with advice of counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the other party or that a material conflict
of interest between such parties may exist in respect of such Proceeding, then
the Indemnifying Party may decline to assume the defense on behalf of the
Indemnified Party or the Indemnified Party may retain the defense on its own
behalf, and, in either such case, after notice to such effect is duly given
hereunder to the other party, the Indemnifying Party shall be relieved of its
obligation to assume the defense on behalf of the Indemnified Party, but shall
be required to pay any legal or other expenses

                                     -37-
<PAGE>

including, without limitation, reasonable attorneys' fees and disbursements,
incurred by the Indemnified Party in such defense.

          (d)  If the Indemnifying Party assumes the defense of such Proceeding,
the Indemnified Party shall cooperate fully with the Indemnifying Party and
shall appear and give testimony, produce documents and other tangible evidence,
allow the Indemnifying Party access to the books and records of the Indemnified
Party and otherwise assist the Indemnifying Party in conducting such defense. No
Indemnifying Party shall, without the consent of the Indemnified Party, consent
to entry of any judgment or enter into any settlement or compromise which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
of such claim or Proceeding; provided, however, the Indemnified Party shall have
                             --------
the sole and exclusive right to consent to entry of any judgment or enter into
any settlement or compromise on such terms and conditions as it deems
appropriate to the extent such claim or Proceeding involves equitable or other
non-monetary relief. Provided that proper notice is duly given, if the
Indemnifying Party shall fail promptly and diligently to assume the defense
thereof, then the Indemnified Party may respond to, contest and defend against
such Proceeding (but the Indemnifying Party shall have the right to participate
at its own cost and expense in such defense by counsel of its own choice) and
may make in good faith any compromise or settlement with respect thereto
(subject to this Section 7.6(d)), and recover from the Indemnifying Party the
entire cost and expense thereof including, without limitation, reasonable
attorneys' fees and disbursements and all amounts paid or foregone as a result
of such Proceeding, or the settlement or compromise thereof. The indemnification
required hereunder shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as and when bills or invoices
are received or loss, liability, obligation, damage or expense is actually
suffered or incurred.

     9.2  Interpretation.  The words "include," "includes" and "including" when
          --------------
used herein shall be deemed in each case to be followed by the words "without
limitation." The word "agreement" when used herein shall be deemed in each case
to mean any contract, commitment or other agreement, whether oral or written,
that is legally binding. As used in this Agreement, the phrase "to the best of
[a party's] knowledge," "to [a party's] knowledge," "[a party] is not aware,"
and similar phrases shall mean the actual knowledge of such party, or of the
officers and directors of such party. The table of contents and headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement.

     9.3  Material Adverse Effect.  The term "Material Adverse Effect" with
          -----------------------
respect to any person means a material adverse effect on the business, financial
condition, assets (including intangible assets) or results of operations of such
person and subsidiaries of such person taken as a whole.

     9.4  Counterparts.  This Agreement may be executed in one or more
          ------------
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

     9.5  Entire Agreement; Assignment.  This Agreement, the schedules and
          ----------------------------
Exhibits hereto, and the documents and instruments and other agreements among
the parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect to the subject matter

                                     -41-
<PAGE>

hereof and supersede all prior agreements and understandings, both written and
oral, among the parties with respect to the subject matter hereof; (b) are not
intended to confer upon any other person any rights or remedies hereunder; and
(c) shall not be assigned by operation of law or otherwise except as otherwise
specifically provided, except that Acquiror may assign its respective rights and
delegate its obligations (other than the obligation of Acquiror to issue
Acquiror Common Stock in the Merger) hereunder to their respective affiliates.

     9.6  Severability.  In the event that any provision of this Agreement or
          ------------
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

     9.7  Other Remedies.  Except as otherwise provided herein, any and all
          --------------
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

     9.8  Governing Law.  This Agreement shall be governed by and construed in
          -------------
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
Each of the parties hereto agrees that process may be served upon them in any
manner authorized by the laws of the State of Delaware for such persons and
waives and covenants not to assert or plead any objection which they might
otherwise have to such jurisdiction and such process.

     9.9  Rules of Construction.  The parties hereto agree that they have been
          ---------------------
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

     9.10 Stock Certificate Legends.  Each certificate representing any of the
shares of Acquiror Common Stock to be issued pursuant to this Agreement shall
have endorsed thereon a legend substantially as follows:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"). SUCH SHARES MAY NOT BE SOLD, TRANSFERRED OR PLEDGED UNLESS:
(i) A REGISTRATION STATEMENT UNDER THE ACT IS IN EFFECT AS TO SUCH SHARES, OR
(ii) THE COMPANY RECEIVES AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE
COMPANY) REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE, TRANSFER OR PLEDGE
IS EXEMPT

                                     -42-
<PAGE>

FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT."

     9.11  Amendment.  Except as is otherwise required by applicable law after
           ---------
the Shareholders approve this Agreement, this Agreement may be amended by the
parties hereto at any time by execution of an instrument in writing signed on
behalf of each of the parties hereto.

     9.12  Extension; Waiver.  At any time prior to the Effective Time,
           -----------------
Acquiror, on the one hand, and the Company, on the other, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

     9.13  Arbitration.  Each party agrees that any dispute arising out of or
           -----------
relating to this Agreement shall be resolved by binding arbitration to be held
in New York, New York. All claims shall be resolved by three arbitrators in
accordance with the Commercial Arbitration Rules then in effect of the American
Arbitration Association (the "Arbitration Rules"). Acquiror and the Company
shall each designate one (1) arbitrator and such designated arbitrators shall
mutually agree upon and shall designate a third arbitrator (the "third
arbitrator"). Any award rendered in any such arbitration proceeding shall be
non-appealable, and final and binding upon the parties (and any attempted appeal
shall be void and of no effect), and judgment thereon may be entered by any
court of competent jurisdiction and application may be made to such court for
judicial confirmation of any award and an order of enforcement, as the case may
be. Each party shall bear its own fees (including its designated arbitrator's
fees and attorney's fees) and other expenses associated with the arbitration,
including fifty percent of the fees of the third arbitrator. However, the
arbitrators shall have the discretion to declare one party the prevailing party
such that the non-prevailing party bears all costs associated with such
arbitration.
