                                       RECITALS

    A.   Parent, the Company and QP ACQUISITION CORP., a California corporation
and a wholly owned subsidiary of Parent ('Merger Sub'), have entered into an
Agreement and Plan of Reorganization dated as of September 3, 1997 (the
'Reorganization Agreement'), pursuant to which Merger Sub is merging with and
into the Company in a transaction in which issued and outstanding capital stock
of the Company will be exchanged for shares of Common Stock, $.001 par value, of
Parent ('Parent Common Stock').

    B.   The Reorganization Agreement contemplates the establishment of an
escrow arrangement to secure the indemnification and other obligations of the
Company under the Reorganization Agreement and various related agreements.


                                      AGREEMENT

    The parties to this Escrow Agreement, intending to be legally bound, agree
as follows:


SECTION 1.    DEFINED TERMS

    Capitalized terms used and not otherwise defined in this Escrow Agreement
shall have the meanings assigned to them in the Reorganization Agreement.


SECTION 2.    CONSENT OF THE SHAREHOLDERS OF THE COMPANY

    By virtue of the approval by the shareholders of the Company of the
Reorganization Agreement, the shareholders of the Company receiving shares of
Parent Common Stock in the Merger (the 'Shareholders') have, without any further
act of any such Shareholder, consented to (i) the establishment of an escrow
(the 'Escrow') pursuant to this Agreement to secure the indemnification
obligations of the Company under Section 9 of the Reorganization Agreement, (ii)
the appointment of the Agent as agent for the Shareholders in all respects as
set forth in Section 10.1 of the Reorganization Agreement, (iii) the taking by

                                          1.


actions, including the execution by the Agent of any and all agreements,
instruments or other documents, and (iv) all of the other terms and conditions
of this Agreement.


SECTION 3.    ESCROW

    3.1  SHARES AND STOCK POWERS TO BE PLACED IN ESCROW.  Parent shall issue
certificates for the aggregate number of shares of Parent Common Stock issuable
by Parent in the Merger pursuant to clause (B) of each of clause (i), (ii),
(iii) and (iv) of Section 1.5(a) of the Reorganization Agreement (the 'Escrow
Shares') in the name of the Escrow Agent evidencing the shares of Parent Common
Stock to be held in escrow in accordance with this Escrow Agreement.  The Escrow
Shares shall be held by the Escrow Agent in the Escrow in accordance with the
provisions of this Escrow Agreement and shall not be subject to any lien,
attachment, trustee process or any other judicial process of any creditor of any
party hereto or the Shareholders.  Parent may from time to time deposit in the
Escrow additional shares of Parent Common Stock pursuant to Sections 1.6 or 1.10
of the Reorganization Agreement and such shares shall be deemed to have been
deposited in the Escrow at the Effective Time.  All such shares shall be deemed
Escrow Shares, and the Persons with rights in respect of such Escrow Shares
shall be deemed Shareholders, for all purposes hereunder.

    3.2  INDEMNIFICATION.  The Company has agreed in Section 9 of the
Reorganization Agreement that each of the Indemnitees shall be held harmless and
indemnified from and against, and shall be compensated and reimbursed for, any
Damages incurred as set forth in Section 9 of the Reorganization Agreement.  The
Company, and the Agent on behalf of the Shareholders, expressly agree that the
Escrow Shares (i) shall be security for such indemnity obligation, subject to
the limitations and in the manner provided for in this Agreement and (ii) are
subject to release to Parent or other Indemnitee upon the terms set forth
herein.

    3.3  VOTING OF SHARES.  The Shareholders shall be entitled to vote their
respective proportionate amount of Escrow Shares set forth on Exhibit A.  Parent
shall give the Agent at least as much notice of meetings of shareholders as it
gives its shareholders generally.  The Agent shall promptly inform each
Shareholder of each such meeting and of the matters to be considered at such
meeting.  The Agent shall, in accordance with the instructions received from the
Shareholders, direct the Escrow Agent in writing as to the exercise of voting
rights pertaining to the Escrow Shares as to which such voting instructions have
been received, and the Escrow Agent shall comply with any such written
instructions.  In the absence of such instructions, the Escrow Agent shall not
vote any of the Escrow Shares.  The Agent shall have no obligation to solicit
consents or proxies from the Shareholders for purposes of any such vote.

    3.4  DIVIDENDS, ETC.  Any cash, securities or other property distributable
(whether by way of dividend, stock split or otherwise) in respect of or in
exchange for any Escrow Shares shall not be distributed to the Agent or the
Shareholders, but rather shall be deposited by Parent with the Escrow Agent to
be held in the Escrow.  At the time any Escrow Shares are required to be
released from the Escrow to any Person pursuant to this Escrow Agreement, any
cash, securities or other property previously distributed in respect of or in
exchange for such Escrow Shares shall be released from the Escrow to such
Person.


                                          2.


    3.5  TRANSFERABILITY.  The interests of the Agent and the Shareholders in
the Escrow and in the Escrow Shares shall not be assignable or transferable,
other than by operation of law.  No transfer of any of such interests by
operation of law shall be recognized or given effect until Parent shall have
received written notice of such transfer.

    3.6  FRACTIONAL SHARES.  No fractional shares of Parent Common Stock shall
be retained in or released from the Escrow pursuant to this Escrow Agreement.
In connection with any release of Escrow Shares from the Escrow, any Shareholder
who would otherwise be entitled to receive a fraction of a share of Parent
Common Stock (after aggregating all fractional shares of Parent Common Stock
issuable to such shareholder) shall be paid by Parent in cash the dollar amount
(rounded to the nearest whole cent), without interest, determined by multiplying
such fraction by the Designated Parent Stock Price, and such fraction of a share
shall be returned to Parent.


SECTION 4.    CLAIM PROCEDURES

    4.1  CLAIM NOTICE.  If any Indemnitee determines in good faith that there
is or has been a possible breach by the Company of any representation, warranty,
covenant or other provision set forth in the Reorganization Agreement or other
event giving rise to an indemnification obligation under Section 9.2 of the
Reorganization Agreement (collectively, an 'Indemnification Event'), and if
Parent shall have consented to such Indemnitee asserting a claim for
indemnification pursuant to Section 9.8 of the Reorganization Agreement and such
Indemnitee wishes to make a claim against the Escrow with respect to such
possible Indemnification Event, then such Indemnitee may deliver to each of the
Agent and the Escrow Agent a written notice of such possible Indemnification
Event (a 'Claim Notice') setting forth (i) a brief description of the
circumstances supporting such Indemnitee's belief that such possible
Indemnification Event exists or has occurred, and (ii) a non-binding,
preliminary estimate of the aggregate dollar amount of all Damages that have
arisen and may arise as a direct or indirect result of such possible
Indemnification Event (such aggregate amount being referred to as the 'Claim
Amount').

    4.2  RESPONSE NOTICE.  Within 15 days after the delivery of a Claim Notice
to the Agent, the Agent shall deliver to the Escrow Agent (with a copy to
Parent) a written notice (the 'Response Notice') containing:  (i) instructions
to the effect that Escrow Shares having a Fair Market Value (as defined in
Section 6) equal to the entire Claim Amount set forth in such Claim Notice are
to be released from the Escrow to such Indemnitee; OR (ii) instructions to the
effect that Escrow Shares having a Fair Market Value equal to a specified
portion (but not the entire amount) of the Claim Amount set forth in such Claim
Notice are to be released from the Escrow to such Indemnitee, together with a
statement that the remaining portion of such Claim Amount is being disputed; OR
(iii) a statement that the entire Claim Amount set forth in such Claim Notice is
being disputed.  If no Response Notice is received by the Escrow Agent from the
Agent within 30 days after the delivery of a Claim Notice to the Agent, then the
Agent shall be deemed to have given instructions to the Escrow Agent that Escrow
Shares having a Fair Market Value equal to the entire Claim Amount set forth in
such Claim Notice are to be released to such Indemnitee from the Escrow.


                                          3.


    4.3  RELEASE OF ESCROW SHARES TO INDEMNITEES.

         (a)  If the Agent gives (or is deemed to have given) instructions that
Escrow Shares having a Fair Market Value equal to the entire Claim Amount set
forth in a Claim Notice are to be released from the Escrow to an Indemnitee,
then the Escrow Agent shall be authorized to transfer to such Indemnitee, from
the Escrow, Escrow Shares having a Fair Market Value equal to such Claim Amount.

         (b)  If a Response Notice delivered by the Agent in response to a
Claim Notice contains instructions to the effect that Escrow Shares having a
Fair Market Value equal to a specified portion (but not the entire amount) of
the Claim Amount set forth in such Claim Notice are to be released from the
Escrow to an Indemnitee, then (i) the Escrow Agent shall be authorized to
transfer to such Indemnitee, from the Escrow, Escrow Shares having a Fair Market
Value equal to such specified portion of such Claim Amount, and (ii) the
procedures set forth in Section 4.3(c) shall be followed with respect to the
remaining portion of such Claim Amount.

         (c)  If a Response Notice delivered by the Agent in response to a
Claim Notice contains a statement that all or a portion of the Claim Amount set
forth in such Claim Notice is being disputed (such Claim Amount or the disputed
portion thereof being referred to as the 'Disputed Amount'), then,
notwithstanding anything contained in Section 5, the Escrow Agent shall continue
to hold in the Escrow (in addition to any other Escrow Shares permitted to be
retained in the Escrow, whether in connection with any other dispute or
otherwise), Escrow Shares having a Fair Market Value equal to 125% of the
Disputed Amount.  Such Escrow Shares shall continue to be held in the Escrow
until such time as (i) the applicable Indemnitee and the Agent execute a
settlement agreement containing instructions regarding the release of such
shares, or (ii) the Escrow Agent receives a copy of a court order containing
instructions to the Escrow Agent regarding the release of such Escrow Shares.
The Escrow Agent shall thereupon release such Escrow Shares from the Escrow in
accordance with the instructions set forth in such settlement agreement or court
order.  (The parties acknowledge that it is appropriate to retain more than 100%
of the Claim Amount in the Escrow in recognition of the fact that the Indemnitee
may have underestimated the aggregate amount of the actual and potential Damages
arising from a particular Indemnification Event, and to cover interest on such
Claim Amount in accordance with Section 9.6 of the Reorganization Agreement.)

         (d)  Notwithstanding anything to the contrary set forth in this
Section 4, the Escrow Agent shall not release to an Indemnitee, and no
Indemnitee shall be entitled to receive, any Escrow Shares in respect of
indemnification obligations under Section 9 of the Reorganization Agreement for
claims not in respect of or relating to Disputes ('Non-Dispute Indemnification
Claims') if the total number of Escrow Shares previously released to Indemnitees
together with the number of Escrow Shares being released to such Indemnitee
collectively in respect of Non-Dispute Indemnification Claims shall exceed
77,700 shares; PROVIDED, HOWEVER, that the Escrow Agent shall be entitled to
release, and an Indemnitee shall be entitled to receive, up to such number of
Escrow Shares in respect of a Non-Dispute Indemnification Claim as shall not
cause such 77,700 share aggregate maximum to be exceeded.


                                          4.


SECTION 5.    RELEASE OF SHARES TO SHAREHOLDERS

    5.1  SHARES TO BE RELEASED.  On the date 12 months after the Closing Date
(the 'Scheduled Escrow Termination Date'), the Escrow Agent shall release to the
Shareholders from the Escrow all Escrow Shares then held in the Escrow, other
than any Escrow Shares that are to be retained in the Escrow in accordance with
Section 4.3(c).  From and after the Scheduled Escrow Termination Date and upon
the resolution of a dispute (and the release of Escrow Shares to Indemnitees in
respect of such dispute, if any) in accordance with Section 4.3(c), Parent shall
release to the Shareholders any Escrow Shares remaining in the Escrow in respect
of such dispute.

    5.2  PROCEDURES FOR RELEASING SHARES.

         (a)  In the event that the Escrow Agent is to release Escrow Shares to
the Shareholders in accordance with Section 5.1, the Escrow Agent shall be
authorized to transfer to each Shareholder, and shall so transfer and release to
each Shareholder, such number of Escrow Shares, subject to Section 3.6, as shall
equal the total number of Escrow Shares to be so transferred and released
multiplied by the fraction (i) having a numerator equal to the number of shares
of Parent Common Stock set forth opposite such Shareholder's name on Exhibit A
hereto and (ii) having a denominator equal to the total number of Escrow Shares
listed on Exhibit A.

         (b)  Any release of shares to the Shareholders pursuant to Section 5.1
may be effected by mailing a stock certificate to the Shareholders certified
mail, return receipt requested.


SECTION 6.    VALUATION OF SHARES HELD IN ESCROW

    For purposes of this Escrow Agreement, the 'Fair Market Value' of the
Escrow Shares shall be deemed to be equal to the number of Escrow Shares
multiplied by the Designated Parent Stock Price (adjusted as appropriate to
reflect any stock split, reverse stock split, stock dividend or similar
transaction effected by Parent after the Closing Date).


SECTION 7.    FEES AND EXPENSES

    7.1  ESCROW AGENT FEES AND EXPENSES.  Upon execution of this Escrow
Agreement and initial deposit of the Escrow Shares, an acceptance fee of
$___________ will be payable to the Escrow Agent.  This acceptance fee will
cover the first year of the Escrow.  Thereafter, an annual administrative fee
will be payable in accordance with the Escrow Agent's fee schedules in effect
from time to time.  The Escrow Agent will also be entitled to reimbursement for
extraordinary expenses incurred in performance of its duties hereunder.

    7.2  PAYMENT OF ESCROW AGENT.  Parent shall pay the fees and expenses of
the Escrow Agent for the services to be rendered by the Escrow Agent hereunder.
Parent shall be entitled to reimbursement of one-half of such fees and expenses
from the Shareholders.


                                          5.


    7.3  AGENT'S FEES AND EXPENSES.  All reasonable expenses (including
attorneys' fees) incurred by the Agent in connection with the performance of its
duties hereunder shall be reimbursed to the Agent by the Shareholders.  Parent
shall not be obligated to reimburse the Agent for any fees charged or expenses
(including attorneys' fees) incurred by the Agent in connection with the Agent's
performance of his duties hereunder.  The Agent hereby agrees that he shall not
seek payment or reimbursement of any such fees and expenses, if any, from
Parent, the Surviving Corporation or the Company, and that the Agent shall only
seek payment or reimbursement of all such fees and expenses from the
Shareholders.

    7.4  REIMBURSEMENT PROCEDURES.  Upon a notice in writing delivered to the
Escrow Agent by Parent in respect of Section 7.2 or Section 8.2, or by the Agent
in respect of Section 7.3, the Escrow Agent shall transfer, deliver and assign
to the Person delivering the notice, in reimbursement of fees and expenses
pursuant to Section 7.2, Section 7.3 or Section 8.2, such number of Escrow
Shares held in the Escrow Account which have a Fair Market Value equal to the
amount to be reimbursed.  Notwithstanding the foregoing, the Agent's right of
reimbursement from the Escrow Shares shall be in all respects subordinate to
rights of Parent in respect of the Escrow Shares.  The Escrow Agent shall
transfer shares to the Agent in reimbursement of its expenses only at such time
as Escrow Shares are otherwise distributable pursuant to the terms of this
Agreement to the Shareholders.


SECTION 8.    LIMITATION OF ESCROW AGENT'S LIABILITY

    8.1  LIMITATION.  The Escrow Agent shall incur no liability with respect to
any action taken or suffered by it in reliance upon any notice, direction,
instruction, consent, statement or other documents believed by it to be genuine
and duly authorized, nor for other action or inaction except its own willful
misconduct or negligence.  The Escrow Agent shall not be responsible for the
validity or sufficiency of this Agreement.  In all questions arising under the
Escrow Agreement, the Escrow Agent may rely on the advice of counsel, and for
anything done, omitted or suffered in good faith by the Escrow Agent based on
such advice the Escrow Agent shall not be liable to anyone.  The Escrow Agent
shall not be required to take any action hereunder involving any expense unless
the payment of such expense is made or provided for in a manner reasonably
satisfactory to it.

    8.2  INDEMNIFICATION OF ESCROW AGENT.  Parent and the Shareholders, jointly
and severally, shall indemnify the Escrow Agent for, and hold it harmless
against, any loss, liability or expense incurred without negligence or willful
misconduct on the part of Escrow Agent, arising out of or in connection with its
carrying out of its duties hereunder.  As among themselves, each of (i) Parent
and (ii) the Shareholders shall be liable for one-half (1/2) of such amounts and
Parent shall be entitled to reimbursement from the Escrow Shares of the
Shareholders' share of any such loss, liability or expense.


                                          6.


SECTION 9.    SUCCESSOR ESCROW AGENT

    In the event the Escrow Agent becomes unavailable or unwilling to continue
in its capacity herewith, the Escrow Agent may resign and be discharged from its
duties or obligations hereunder by giving resignation to the parties to this
Escrow Agreement, specifying not less than 60 days' prior written notice of the
date when such resignation shall take effect.  Parent may appoint a successor
Escrow Agent without the consent of the Agent so long as such successor is a
bank with assets of at least $100 million, and may appoint any other successor
Escrow Agent with the consent of the Agent, which consent shall not be
unreasonably withheld.  If, within such notice period, Parent provides to the
Escrow Agent written instructions with respect to the appointment of a successor
Escrow Agent and directions for the transfer of any Escrow Shares then held by
the Escrow Agent to such successor, the Escrow Agent shall act in accordance
with such instructions and promptly transfer such Escrow Shares to such
designated successor.


SECTION 10.   GENERAL

    10.1 ADJUSTMENT OF EXHIBIT A.  If and when Parent deposits additional
Escrow Shares with the Escrow Agent, Parent shall revise Exhibit A to reflect
such deposit.  In connection therewith, Parent may as appropriate alter the
identity of the Shareholders listed on Exhibit A and the number of Escrow Shares
set forth opposite the appropriate Shareholders' names, including appropriate
adjustments with respect to the incidence of any prior release of shares of
Parent Common Stock to an Indemnitee as permitted in Section 1.6 of the
Reorganization Agreement.  Parent may deliver any revised Exhibit A in
accordance with Section 10.3.  Upon such delivery, any such revised Exhibit A
(i) shall be deemed appended to this Agreement in replacement of the prior
Exhibit A and (ii) shall constitute Exhibit A for all purposes under this
Agreement.

    10.2 OTHER AGREEMENTS.     Nothing in this Escrow Agreement is intended to
