         Stock as is equal to 0.12 multiplied by the Series C Fraction if and
         when released, in whole or in part, from escrow pursuant to the terms
         of the Escrow Agreement;

              (v)  each share of the common stock, $0.001 par value, of Merger
         Sub outstanding immediately prior to the Effective Time shall be
         converted into one share of common stock of the Surviving Corporation.

         (b)  Each share of Company Common Stock, Series A Stock, Series B
Stock, Series C Stock outstanding immediately prior to the Effective Time and
owned by Parent and each share of Series D Preferred stock, no par value, of the
Company ("Series D Stock") outstanding immediately prior to the Effective Time,
all of which are owned by Parent, shall automatically be canceled and no
conversion shall be made in respect thereof.

         (c)  For purposes of this Agreement:

              (i)  The "Applicable Fraction" shall be the fraction: (A) having
         a numerator equal to the amount determined by subtracting (1) the
         "Aggregate Liquidation Preference" (as defined in Section 1.5(c)(vi))
         from (2) the amount determined by multiplying (i) 777,000 by (ii) the
         Designated Parent Stock Price (as defined in Section 1.5(c)(viii));
         and (B) having a denominator equal to the amount determined by
         multiplying (1) the "Adjusted Fully Diluted Company Share Amount" (as
         defined in Section 1.5(c)(vii)) by (2) the "Designated Parent Stock
         Price" (as defined in Section 1.5(c)(viii));

              (ii) The "Series A Fraction" means the sum of:  (A) the fraction
         determined by dividing (1) $1.50 (representing the liquidation
         preference of each share of Series A Stock under the Company's
         Articles of Incorporation) by (2) the "Designated Parent Stock Price"
         (as defined in Section 1.5(c)(viii)); and (B)


                                          3


         the fraction determined by multiplying (1) the "Series A Conversion
         Rate" (as defined in Section 1.5(c)(iii)) by (2) the "Applicable
         Fraction" (as defined in Section 1.5(c)(i));

              (iii)     The "Series A Conversion Rate" shall be the fraction
         determined by dividing (1) the total number of shares of Common Stock
         issuable upon the conversion of all shares of Series A Stock
         outstanding immediately prior to the Effective Time by (2) the total
         number of shares of Series A Stock outstanding immediately prior to
         the Effective Time.

              (iv) The "Series B Fraction" means the fraction determined by
         dividing (A) $0.75 (representing the liquidation preference of each
         share of Series B Stock under the Company's Articles of Incorporation)
         by (B) the "Designated Parent Stock Price" (as defined in Section
         1.5(c)(viii));

              (v)  The "Series C Fraction" means the sum of:  (A) the fraction
         determined by dividing (1) $1.00 (representing the liquidation
         preference of each share of Series C Stock under the Company's
         Articles of Incorporation) by (2) the "Designated Parent Stock Price"
         (as defined in Section 1.5(c)(viii)); and (B) the "Applicable
         Fraction" (as defined in Section 1.5(c)(i));

              (vi) The "Aggregate Liquidation Preference" shall be the amount
         equal to the sum of:  (A) $1.50 (representing the liquidation
         preference of each share of Series A Stock under the Company's

         Series A Stock outstanding immediately prior to the Effective Time;
         (B) $0.75 (representing the liquidation preference of each share of

         the liquidation preference of each share of Series C Stock under the
         Company's Articles of Incorporation) multiplied by the number of
         shares of Series C Stock outstanding immediately prior to the
         Effective Time;

              (vii) The "Adjusted Fully Diluted Company Share Amount" shall

         from (2) the aggregate number of shares of Company Common Stock
         outstanding immediately prior to the Effective Time (including any
         such shares that are subject to a repurchase option or risk of
         forfeiture under any restricted stock purchase agreement or other
         agreement); (B) the aggregate number of shares of Company Common Stock
         issuable upon conversion of all of the Series A Stock and Series C 
         Stock collectively outstanding immediately prior to the Effective Time 
         and not held by Parent; and (C) the aggregate number of shares of 
         Company Common Stock purchasable under or otherwise subject to all 
         Company Options (as defined in Section 1.6) outstanding immediately 
         prior to the Effective Time (including all


                                          4


         shares of Company Common Stock that may ultimately be purchased under
         Company Options that are unvested or are otherwise not then
         exercisable); and

              (viii) The "Designated Parent Stock Price" shall be the
         average of the closing sale prices of a share of Parent Common Stock
         as reported on the Nasdaq National Market for each of the sixty (60)
         consecutive trading days ending (and including) the third trading day
         prior to the Company Shareholders Meeting, weighted in accordance with
         the number of shares of Parent Common Stock traded on each such
         trading day.

         (d)  If any shares of Company Common Stock outstanding immediately
prior to the Effective Time are unvested or are subject to a repurchase option,
risk of forfeiture or other condition under any applicable restricted stock
purchase agreement or other agreement with the Company, then the shares of
Parent Common Stock issued in exchange for such shares of Company Common Stock
will also be unvested and subject to the same repurchase option, risk of
forfeiture or other condition, and the certificates representing such shares of
Parent Common Stock may accordingly be marked with appropriate legends.

         (e)  All calculations made pursuant to this Section 1.5 shall be
calculated to the nearest fifth decimal place, with five millionths rounded up
to the nearest one-hundred-thousandth.

    1.6  EMPLOYEE STOCK OPTIONS.  At the Effective Time, each stock option that
is then outstanding under the Company's 1994 Qualified and Nonqualified Stock
Option Plan (the "Company Stock Plan"), whether vested or unvested (a "Company
Option"), shall be assumed by Parent in accordance with the terms (as in effect
as of the date of this Agreement) of the Company Stock Plan and the stock option
agreement by which such Company Option is evidenced.  All rights with respect to
Company Common Stock under outstanding Company Options shall thereupon be
converted into rights with respect to Parent Common Stock.  Accordingly, from
and after the Effective Time, (a) each Company Option assumed by Parent may be
exercised solely for shares of Parent Common Stock, (b) the number of shares of
Parent Common Stock subject to each such assumed Company Option shall be equal
to the number of shares of Company Common Stock that were subject to such
Company Option immediately prior to the Effective Time multiplied by the
Applicable Fraction, rounded down to the nearest whole number of shares of
Parent Common Stock, (c) the per share exercise price for the Parent Common
Stock issuable upon exercise of each such assumed Company Option shall be
determined by dividing the exercise price per share of Company Common Stock
subject to such Company Option, as in effect immediately prior to the Effective
Time, by the Applicable Fraction, and rounding the resulting exercise price up
to the nearest whole cent, and (d) all restrictions on the exercise of each such
assumed Company Option shall continue in full force and effect, and the term,
exercisability, vesting schedule and other provisions of such Company Option
shall otherwise remain unchanged; PROVIDED, HOWEVER, that each such assumed
Company Option shall, in accordance with its terms, be subject to further
adjustment as appropriate to reflect any stock split, reverse stock split, stock
dividend, recapitalization or other similar transaction effected by Parent after
the Effective Time; PROVIDED FURTHER, that upon the issuance of Parent Common
Stock pursuant to the exercise of an assumed Company Option prior to the


                                          5


release of all shares of Parent Common Stock held in escrow pursuant to the
Escrow Agreement, (i) Parent shall issue to the Person exercising such assumed
Company Option only that portion of the shares of Parent Common Stock issuable
upon suchexercise of such assumed Company Option that such holder would have
received had such assumed Company Option been exercised prior to the Effective
Time and converted into shares of Parent Common Stock pursuant to Section
1.5(a)(i), (ii) the remainder of the shares of Parent Common Stock issuable upon
the exercise of such assumed Company Option shall be held in escrow pursuant to
the terms of the Escrow Agreement, and (iii) any such shares of Parent Common
Stock shall be deemed to have been deposited into escrow as of the Effective
Time and appropriate adjustments shall be made in Exhibit A of the Escrow
Agreement with respect to the incidence of any prior release of shares of Parent
Common Stock to an Indemnitee, so that any such Person bears a proportionate
share of any release to an Indemnitee that occurs after the Effective Time.  The
Company and Parent shall take all actions that may be necessary (under the
Company Stock Plan and otherwise) to effectuate the provisions of this Section
1.6.  Following the Closing, Parent will send to each holder of an assumed
Company Option a written notice setting forth (i) the number of shares of Parent
Common Stock subject to such assumed Company Option, and (ii) the exercise price
per share of Parent Common Stock issuable upon exercise of such assumed Company
Option.  Parent shall file with the SEC, within sixty (60) days after the
Closing Date, a registration statement on Form S-8 registering the exercise of
the Company Options assumed by Parent pursuant to this Section 1.6.


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

    1.8  EXCHANGE OF CERTIFICATES.

         (a)  At or as soon as practicable after the Effective Time, Parent
will send to the holders of Company Stock Certificates (i) a letter of
transmittal in customary form and containing such provisions as Parent may
reasonably specify, and (ii) instructions for use in effecting the surrender of
Company Stock Certificates in exchange for certificates representing Parent
Common Stock.  Upon surrender of a Company Stock Certificate to Parent for
exchange, together with a duly executed letter of transmittal and such other
documents as may be reasonably required by Parent, the holder of such Company
Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of Parent Common Stock that
such holder has the right to receive pursuant to the provisions of this Section
1, and the Company Stock Certificate so surrendered shall be canceled.  Until
surrendered as contemplated by this Section 1.8, each Company Stock Certificate
shall be deemed, from and after the Effective Time, to represent only the right
to receive upon such surrender a certificate


                                          6


representing shares of Parent Common Stock (and cash in lieu of any fractional
share of Parent Common Stock) as contemplated by this Section 1.  If any Company
Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its
discretion and as a condition precedent to the issuance of any certificate
representing Parent Common Stock, require the owner of such lost, stolen or
destroyed Company Stock Certificate to provide an appropriate affidavit and to
deliver a bond (in such sum as Parent may reasonably direct) as indemnity
against any claim that may be made against Parent or the Surviving Corporation
with respect to such Company Stock Certificate.

         (b)  No dividends or other distributions declared or made with respect
to Parent Common Stock with a record date after the Effective Time shall be paid
to the holder of any unsurrendered Company Stock Certificate with respect to the
shares of Parent Common Stock represented thereby, and no cash payment in lieu
of any fractional share shall be paid to any such holder, until such holder
surrenders such Company Stock Certificate in accordance with this Section 1.8
(at which time such holder shall be entitled to receive all such dividends and
distributions and such cash payment).

         (c)  No fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and no certificates for any such fractional shares
shall be issued.  In lieu of such fractional shares, any holder of capital stock
of the Company 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 holder) shall, upon surrender of such holder's Company
Stock Certificate(s), be paid in cash the dollar amount (rounded to the nearest
whole cent), without interest, determined by multiplying such fraction by the
Designated Parent Stock Price.

         (d)  Parent and the Surviving Corporation shall be entitled to deduct
and withhold from any consideration payable or otherwise deliverable to any
holder or former holder of capital stock of the Company pursuant to this
Agreement such amounts as Parent or the Surviving Corporation may be required to
deduct or withhold therefrom under the Code or under any provision of state,
local or foreign tax law.  To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the Person to whom such amounts would otherwise have been
paid.

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

    1.9  DISSENTING SHARES.

         (a)  Notwithstanding anything to the contrary contained in this
Agreement, any shares of capital stock of the Company that, as of the Effective
Time, are or may become "dissenting shares" within the meaning of Section
1300(b) of the California Corporations Code shall not be converted into or
represent the right to receive Parent Common Stock in accordance with Section
1.5 (or cash in lieu of fractional shares in accordance with Section 1.8(c)),
and the


                                          7


holder or holders of such shares shall be entitled only to such rights
as may be granted to such holder or holders in Chapter 13 of the California
General Corporation Law; PROVIDED, HOWEVER, that if the status of any such
shares as "dissenting shares" shall not be perfected, or if any such shares
shall lose their status as "dissenting shares," then, as of the later of the
Effective Time or the time of the failure to perfect such status or the loss of
such status, such shares shall automatically be converted into and shall
represent only the right to receive (upon the surrender of the certificate or
certificates representing such shares) Parent Common Stock in accordance with
Section 1.5 (and cash in lieu of fractional shares in accordance with Section
1.8(c)).

         (b)  The Company shall give Parent (i) prompt notice of any written
demand received by the Company prior to the Effective Time to require the
Company to purchase shares of capital stock of the Company pursuant to Chapter
13 of the California General Corporation Law and of any other demand, notice or
instrument delivered to the Company prior to the Effective Time pursuant to the
California General Corporation Law, and (ii) the opportunity to participate in
all negotiations and proceedings with respect to any such demand, notice or
instrument.  The Company shall not make any payment or settlement offer prior to
the Effective Time with respect to any such demand unless Parent shall have
consented in writing to such payment or settlement offer.

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

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

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

the dollar amount of such reserves to Parent on or prior to the Closing Date.


                                          22


         (c)  No Company Return relating to income Taxes has ever been examined

similar document received by the Company with respect to any Tax (other than
liabilities for Taxes asserted under any such notice of deficiency or similar
document which are being contested in good faith by the Company and with respect
to which adequate reserves for payment have been established).  There are no
liens for Taxes upon any of the assets of the Company except liens for current
Taxes not yet due and payable.  The Company has not entered into or become bound
by any agreement or consent pursuant to Section 341(f) of the Code.  The Company

taxable income for any tax period (or portion thereof) pursuant to Section 481
or 263A of the Code or any comparable provision under state or foreign Tax laws
as a result of transactions or events occurring, or accounting methods employed,
prior to the Closing.

         (e)  There is no agreement, plan, arrangement or other Contract
covering any employee or independent contractor or former employee or

value in excess of $10,000 in the aggregate.

the Company does not maintain, sponsor or contribute to, and, to the best of the
knowledge of the Company, has not at any time in the past maintained, sponsored
or contributed to, any employee


                                          23


pension benefit plan (as defined in Section 3(2) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), whether or not excluded from
coverage under specific Titles or Merger Subtitles of ERISA) for the benefit of
Employees or former Employees (a "Pension Plan").

         (c)  The Company maintains, sponsors or contributes only to those
employee welfare benefit plans (as defined in Section 3(1) of ERISA, whether or
not excluded from coverage under specific Titles or Merger Subtitles of ERISA)
for the benefit of Employees or former Employees which are described in Part
2.15(c) of the Disclosure Schedule (the "Welfare Plans"), none of which is a
multiemployer plan (within the meaning of Section 3(37) of ERISA).

         (d)  With respect to each Plan, the Company has delivered to Parent:

              (i)  an accurate and complete copy of such Plan (including all

         and complete copies the most recent financial statements thereof;

              (v)  accurate and complete copies of all Contracts relating to
         such Plan, including service provider agreements, insurance contracts,
         minimum premium contracts, stop-loss agreements, investment management

         Section 401(a) of the Code).

         (e)  The Company is not required to be, and, to the best of the
knowledge of the Company, has never been required to be, treated as a single
employer with any other Person under Section 4001(b)(1) of ERISA or Section
414(b), (c), (m) or (o) of the Code.  The Company has never been a member of an
"affiliated service group" within the meaning of Section 414(m) of the Code.  To
the best of the knowledge of the Company, the Company has never made a complete
or partial withdrawal from a multiemployer plan, as such term is defined in
Section 3(37) of ERISA, resulting in "withdrawal liability," as such term is
defined in


                                          24


Section 4201 of ERISA (without regard to subsequent reduction or waiver of such
liability under either Section 4207 or 4208 of ERISA).

         (f)  The Company does not have any plan or commitment to create any
additional Welfare Plan or any Pension Plan, or to modify or change any existing
Welfare Plan or Pension Plan (other than to comply with applicable law) in a
manner that would affect any Employee.

         (g)   Except as set forth in Part 2.15(g) of the Disclosure Schedule,
no Welfare Plan provides death, medical or health benefits (whether or not
insured) with respect to any current or former Employee after any such
Employee's termination of service (other than (i) benefit coverage mandated by
applicable law, including coverage provided pursuant to Section 4980B of the
Code, (ii) deferred compensation benefits accrued as liabilities on the
Unaudited Interim Balance Sheet, and (iii) benefits the full cost of which are
borne by current or former Employees (or the Employees' beneficiaries)).

         (h)  With respect to each of the Welfare Plans constituting a group
health plan within the meaning of Section 4980B(g)(2) of the Code, the
provisions of Section 4980B of the Code ("COBRA") have been complied with in all
material respects.

         (i)  Each of the Plans has been operated and administered in all
material respects in accordance with applicable Legal Requirements, including
but not limited to ERISA and the Code.

         (j)  Each of the Plans intended to be qualified under Section 401(a)
of the Code has received a favorable determination from the Internal Revenue
Service, and the Company is not aware of any reason why any such determination
letter should be revoked.

         (k)  Except as set forth in Part 2.15(k) of the Disclosure Schedule,
neither the execution, delivery or performance of this Agreement, nor the
consummation of the Merger or any of the other transactions contemplated by this
Agreement, will result in any payment (including any bonus, golden parachute or
severance payment) to any current or former Employee or director of the Company
(whether or not under any Plan), or materially increase the benefits payable
under any Plan, or result in any acceleration of the time of payment or vesting
of any such benefits.

         (l)  Part 2.15(l) of the Disclosure Schedule contains a list of all
salaried employees of the Company as of the date of this Agreement, and
correctly reflects, in all material respects, their salaries, any other
compensation payable to them (including compensation payable pursuant to bonus,
deferred compensation or commission arrangements), their dates of employment and
their positions.  The Company is not a party to any collective bargaining
contract or other Contract with a labor union involving any of its Employees.
All of the Company's employees are "at will" employees.


                                          25


         (m)  Part 2.15(m) of the Disclosure Schedule identifies each Employee
who is not fully available to perform work because of disability or other leave
and sets forth the basis of such leave and the anticipated date of return to

on the Company's labor relations, or (ii) any of the Company's employees intends
to terminate his or her employment with the Company.

required under applicable Environmental Laws, and compliance with the terms and

which compliance includes the possession by the Company of all permits and other
Governmental Authorizations required under such applicable laws and compliance
with the terms and conditions thereof.  All Governmental Authorizations
currently


                                          26


held by the Company pursuant to such applicable laws are identified in Part 2.13
of the Disclosure Schedule.  The Company maintains inventory controls and use
and storage procedures to ensure that all Controlled Substances and Explosives
will not be lost, stolen or otherwise go unaccounted for.  The Company is in
possession of all Controlled Substances and Explosives which it has obtained or
used in the course of its business, other than such Controlled Substances and
Explosives that the Company has returned to Governmental Bodies from which such
Controlled Substances and Explosives had been obtained.  No employee of the
Company or other Person has suffered any injury as a result of the use or
handling any Controlled Substances or Explosives on the premises of the Company
or while engaging in their employment activities with the Company.

    2.18 INSURANCE.  Part 2.18 of the Disclosure Schedule identifies all
insurance policies maintained by, at the expense of or for the benefit of the

Company; (ii) each individual who is, or who has at any time since September 30,
1993 been, an officer or director of the Company; (iii)  each member of the

Person whose liability the Company has or may


                                          27


have retained or assumed, either contractually or by operation of law; or (ii)
that challenges, or that may have the effect of preventing, delaying, making
illegal or otherwise interfering with, the Merger or any of the other
transactions contemplated by this Agreement.  To the best of the knowledge of
the Company, except as set forth in Part 2.21 of the Disclosure Schedule, no
event has occurred, and no claim, dispute or other condition or circumstance
exists, that will, or that could reasonably be expected to, give rise to or
serve as a basis for the commencement of any such Legal Proceeding.

         (b)  Except as set forth in Part 2.21 of the Disclosure Schedule, no
Legal Proceeding has ever been commenced by or has ever been pending against the

    with respect to any asset owned or used by the Company (except for minor
    liens that will not, in any case or in the aggregate, materially detract
    from the value of the assets subject thereto or materially impair the
    operations of the Company).

Except as set forth in Part 2.22 of the Disclosure Schedule, the Company is not
and will not be required to make any filing with or give any notice to, or to
obtain any Consent from, any Person in connection with (x) the execution,

the representations and warranties set forth in Section 2 and the
representations and warranties set forth in the Closing Certificate) shall
survive the Closing and shall expire on the first anniversary of the Closing

the Closing Date, any Indemnitee (acting in good faith) delivers to the Agent
(as defined in Section 10.1) a written notice alleging the existence of an
inaccuracy in or a breach of any of the representations and warranties made by
the Company (and setting forth in reasonable detail the basis for such
Indemnitee's belief that such an inaccuracy or breach may exist) and asserting a
claim for recovery under Section 9.2 based on such alleged inaccuracy or breach,
then the claim asserted in such notice shall survive the first anniversary of
the Closing until such time as such claim is fully and finally resolved.  All
representations and warranties made by Parent and Merger Sub shall terminate and
expire as of the Effective Time, and any liability of Parent or Merger Sub with
respect to such representations and warranties shall thereupon cease.


                                          43


         (b)  The representations, warranties, covenants and obligations of the
Company, and the rights and remedies that may be exercised by the Indemnitees,
shall not be limited or otherwise affected by or as a result of any information
furnished to, or any investigation made by or knowledge of, any of the
Indemnitees or any of their Representatives.

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

    9.2  INDEMNIFICATION.

         (a)  From and after the Effective Time (but subject to Section
9.1(a)), each of the Indemnitees shall be held harmless and indemnified from and
against, and shall be compensated and reimbursed for, any Damages which are
directly or indirectly suffered or incurred by any of the Indemnitees or to
which any of the Indemnitees may otherwise become subject (regardless of whether
or not such Damages relate to any third-party claim) and which arise from or as
a result of, or are directly or indirectly connected with:

              (i)  any inaccuracy in or breach of any representation or
    warranty of the Company set forth in this Agreement or in the Closing
    Certificate (without giving effect to any "Material Adverse Effect" or
    other materiality qualification or any similar qualification contained or
    incorporated directly or indirectly in such representation or warranty);

              (ii) any inaccuracy of any representation, warranty, statement,
    information or other provision contained in the Disclosure Schedule or in
    any other document delivered or otherwise made available to Parent or any
    of its Representatives by or on behalf of the Company or any of the
    Company's Representatives;

              (iii)     any breach of any covenant or obligation of the Company
    (including the covenants set forth in Sections 4 and 5);

              (iv) any litigation, arbitration, controversy, dispute or
    disagreement involving the Company and any of EG&G Astrophysics, Rapiscan
    Security Products, Inc., Heimann Systems GmbH or any other person
    identified in Part 2.21 of the Disclosure Schedule or any of their
    respective affiliates (collectively, the "Disputes"); or

              (v)  any Legal Proceeding relating to any inaccuracy or breach or
    other matter of the type referred to in clause "(i)", "(ii)", "(iii)", or
    "(iv)" above (including any Legal Proceeding commenced by any Indemnitee
    for the purpose of enforcing any of its rights under this Section 9).

         (b)  If the Surviving Corporation suffers, incurs or otherwise becomes
subject to any Damages as a result of or in connection with any inaccuracy in or
breach of any representation, warranty, covenant or obligation or any of the
Disputes, then (without limiting


                                          44


any of the rights of the Surviving Corporation as an Indemnitee) Parent shall
also be deemed, by virtue of its ownership of the stock of the Surviving
Corporation, to have incurred Damages as a result of and in connection with such
inaccuracy or breach or Dispute.

    9.3  THRESHOLD.  There shall be no indemnification payment pursuant to
Section 9.2(a) for any inaccuracy in or breach of any of their representations
and warranties set forth in Section 2 until such time as the total amount of all
Damages (including the Damages arising from such inaccuracy or breach and all
other Damages arising from any other inaccuracies in or breaches of any
representations or warranties) that have been directly or indirectly suffered or
incurred by any one or more of the Indemnitees, or to which any one or more of
the Indemnitees has or have otherwise become subject, exceeds $100,000 in the
aggregate.  If the total amount of such Damages exceeds $100,000, then the
Indemnitees shall be entitled to be indemnified against and compensated and
reimbursed for all Damages, including such $100,000.  Notwithstanding anything
to the contrary set forth in this Section 9.3, the $100,000 minimum threshold
shall not apply to Damages arising under the Disputes.

    9.4  SATISFACTION OF INDEMNIFICATION CLAIM.

         (a)  The escrow under the Escrow Agreement shall serve as security for
the obligations owed the Indemnitees under this Section 9.  Any liability (for
indemnification or otherwise) to any Indemnitee under this Section 9 may be
satisfied by the delivery to such Indemnitee, from the shares escrowed pursuant
to the Escrow Agreement, of the number of shares of Parent Common Stock
determined by dividing (i) the aggregate dollar amount of such liability BY (ii)
the Designated Parent Stock Price (as defined in Section 1.5(c)(viii) and as
adjusted as appropriate to reflect any stock split, reverse stock split, stock
dividend, recapitalization or other similar transaction effected by Parent
between the Effective Time and the date such liability is satisfied).

         (b)  Except with respect to claims based on knowing and intentional
misrepresentations of representations and warranties, Parent and Merger Sub
agree that, after the Closing, the sole recourse of the Indemnitees with respect
to a breach by the Company of its representations or warranties made in this
Agreement or in the Disclosure Schedule or the other indemnification rights set
forth in this Section 9 shall be against the shares held in escrow under the
Escrow Agreement.

    9.5  NO CONTRIBUTION.  No Person shall have any right of contribution,
right of indemnity or other right or remedy against the Surviving Corporation in
connection with any indemnification obligation or any other liability under or
in connection with this Agreement or the Closing Certificate.

    9.6  INTEREST.  Any Indemnitee entitled to recover Damages pursuant to this
Section 9 shall also be entitled to interest on the amount of such Damages (for
the period commencing as of the date on which the Agent (as defined in Section
10.1) first received notice of a claim for recovery by such Indemnitee and
ending on the date on which the liability to such Indemnitee is fully satisfied)
at a floating rate equal to the rate of interest publicly announced by Bank of
America, N.T. & S.A. from time to time as its prime, base or reference rate.


                                          45


    9.7  DEFENSE OF THIRD PARTY CLAIMS.  In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against the
Surviving Corporation, against Parent or against any other Person) with respect
to which there may be any obligation to hold harmless, indemnify, compensate or
reimburse any Indemnitee pursuant to this Section 9, Parent shall have the
right, at its election, to proceed with such claim or Legal Proceeding on its
own.  If Parent so proceeds with any such claim or Legal Proceeding:

         (a)  all reasonable expenses relating to such claim or Legal
    Proceeding shall be deemed Damages, subject to recovery by the Indemnitee
    under Section 9.2; and

         (b)  Parent shall have the right to settle, adjust or compromise such
    claim or Legal Proceeding with the consent of the Agent (as defined in
    Section 10.1); PROVIDED, HOWEVER, that such consent shall not be
    unreasonably withheld.

Parent shall give the Agent (as defined in Section 10.1) prompt notice of the
commencement of any such Legal Proceeding against Parent or the Surviving
Corporation; PROVIDED, HOWEVER, that any failure on the part of Parent to so
notify the Agent shall not limit any of the rights of any Indemnitees under this
Section 9 (except to the extent such failure materially prejudices the defense
of such Legal Proceeding).

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

whereby each share of outstanding Common Stock, Series A Preferred Stock, Series

"Company Capital Stock") shall cease to be existing and shall become and convert
into that number of shares of the common stock of Parent ("Parent Common
Stock"), as set forth in the Reorganization Agreement.

    As a result of the Merger and certain related transactions, Shareholder
will receive shares of Parent Common Stock.  The Shareholder understands that
the Parent Common Stock being issued in the Merger will be issued pursuant to a
Registration Statement on Form S-4, and that the Shareholder may be deemed an
"Affiliate" of Parent as such term is defined for purposes of paragraphs (c) and
(d) of Rule 145 ("Rule 145") of the General Rules and Regulations of the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Act"), and the Securities and Exchange Commissions Accounting Series
Release Nos. 130 and 135 (the "Pooling Rules"), as amended, and as such the
Shareholder may only transfer, sell or dispose of the Parent Common Stock in
accordance with this Affiliate Agreement, Rule 145 and the Pooling Rules.

    The Shareholder understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent and the Company, and
their respective counsel and accounting firms.

    1.   The Shareholder represents, warrants, understands and agrees that:

         (a)  The Shareholder has full power and capacity to execute and
deliver this Affiliates Agreement and to make the representations, warranties
and agreements set forth herein and to perform its obligations hereunder.

         (b)  The Shareholder has carefully read this Affiliates Agreement, and
has discussed with counsel to the extent Shareholder felt necessary the
requirements, limitations and restrictions on his or her ability to sell,
transfer or otherwise dispose of the Parent Common Stock he or she may receive
through the Reorganization Agreement, and fully understands the


                                          1.


requirements limitations and restrictions this Affiliates Agreement places upon
the Shareholder's ability to transfer sell or otherwise dispose of the Parent
Common Stock.

         (c)  The Shareholder will not, publicly or privately, sell, transfer
or otherwise dispose of, or reduce the Shareholder's interest in or risk
relating to any Parent Common Stock issued to the Shareholder pursuant to the
Merger, or any Parent Common Stock issued to the Shareholder upon exercise of
any instrument exercisable for Parent Common Stock held by Shareholder until
such time as the financial results covering at least thirty (30) days of
post-Merger combined operations of Parent and the Company have been published by
Parent (within the meaning of the Pooling Rules).

         (d)  Until the earlier of (i) the Closing (as defined in the
Reorganization Agreement) or (ii) the termination of the Reorganization
Agreement, the Shareholder will not sell, transfer or otherwise dispose of, or
reduce the Shareholder's interest in or risk relating to, any Company Capital
Stock or any instrument exercisable for the Company Capital Stock currently
owned by the Shareholder.

         (e)  Subject to Section 1(c) above, the Shareholder will not sell,
pledge, transfer or otherwise dispose of any of the Parent Common Stock issued
to the Shareholder in the Merger unless at such time either (i) such transfer
shall be in conformity with the provisions of Rule 145, (ii) the Shareholder
shall have furnished to Parent an opinion of counsel reasonably satisfactory to
Parent, to the effect that no registration under the Act would be required in
connection with the proposed offer, sale, pledge, transfer or other disposition,
(iii) a registration statement under the Act covering the proposed offer, sale,
pledge, or other disposition shall be effective under the Act, or (iv) if the
Shareholder is a partnership, such transfer shall be a pro rata distribution
from the Shareholder to its partners without receipt of consideration, in which
case each distributee shall receive stock certificates bearing the legend set
forth in paragraph 3 below.

    2.   Shareholder understands and agrees that Parent is under no obligation
to register the sale, transfer or other disposition of the Parent Common Stock
(other than pursuant to the Registration Statement to be filed in connection
with the Merger) or to take any other action necessary in order to make
compliance with an exemption from registration available, except to remain
current in its reporting requirements under the Securities Exchange Act of 1934,
as amended, which Parent hereby agrees to do.

    3.   The Shareholder also understands and agrees that stop transfer
instructions will be given to Parent's transfer agent with respect to the Parent
Common Stock issued to the Shareholder, and there will be placed on the
Certificates representing such Parent Common Stock or any substitutions thereof
(the "Certificates") a legend stating in substance:

    "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
    TRANSACTION TO WHICH RULE 145(d) OF THE SECURITIES ACT OF 1933 APPLIES
    AND MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE PROVISIONS OF SUCH
    RULE.  IN ADDITION, UNTIL [a date one year after the Effective Time],

                                          2.


    CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN
    AGREEMENT DATED AS OF SEPTEMBER __, 1997, BETWEEN THE REGISTERED HOLDER
    HEREOF AND INVISION TECHNOLOGIES, INC., COPIES OF WHICH AGREEMENT IS ON FILE
    AT THE PRINCIPAL OFFICES OF INVISION TECHNOLOGIES, INC."

    4.   Parent agrees that such stop transfer instructions and legends
referred to above will be removed (i) with respect to transferred Parent Common
Stock, at such time as Parent is reasonably satisfied that the Shareholder has
complied with the provisions of this Affiliates Agreement with respect to a
transfer and (ii) otherwise at such time as the restrictions of subsection (d)
of Rule 145 shall no longer apply to the Shareholder.

    5.   The Shareholder further agrees to irrevocably waive and terminate as
of the Closing any rights relating to Parent Common Stock (such as rights to
cause Parent to register such stock) that such Shareholder may possess as the
result of agreements entered into between the Shareholder, other shareholders of
the Company and the Company ("Company Shareholder Agreements") and further
agrees to execute amendments to the Company Shareholder Agreements pursuant to
which they will terminate at the Closing.

    6.   The Shareholder further agrees that, at any time prior to one year
from the Effective Time (as such term is defined in the Reorganization
Agreement), the Shareholder shall only sell shares of Parent Common Stock
received by the Shareholder in the Merger through Donald & Co. Securities Inc.
("Donald & Co."), acting as broker for such transaction.  In addition, in the
event the Shareholder informs Donald & Co. of its intention to sell shares of
Parent Common Stock prior to one year from the Effective Time, Donald & Co.
shall be entitled to inform Parent of the Shareholder's intention to effect such
transaction.  Any such sale shall occur only when otherwise permitted under this
Affiliates Agreement.

    7.   The Shareholder further represents that it is the beneficial owner of
the Company Capital Stock set forth below and the options or warrants to
purchase the Company Capital Stock set forth below.

    8.   The Shareholder and Parent agree that irreparable damages would occur
in the event that any of the provisions of this Affiliates Agreement were not
performed in accordance with their specific terms, or were otherwise breached.
It is, accordingly, agreed that the parties shall be entitled to injunctive
relief to prevent breaches of the provisions of this Affiliates Agreement, and
to enforce specifically the terms and provisions hereof, in addition to any
other remedy to which they may be entitled at law, in equity, by contract or
otherwise.

    9.   This Affiliates Agreement shall be governed in all respects, including
validity, interpretation and effect, by the laws of the State of California
without reference to choice of law provisions.

    10.  This Affiliates Agreement shall be binding upon, and shall be
enforceable by and inure solely to the benefit of, the parties hereto and their
respective successors; PROVIDED, HOWEVER, that Donald & Co. shall be entitled to
rely on Section 6 of this Affiliates Agreement,


                                          3.


 which shall also inure to the benefit of Donald & Co.  This Affiliates
Agreement may not be assigned by any party without the prior written consent of
Parent.  Any attempted assignment not in compliance with this Section 10 shall
be void and of no effect.

    11.  This Affiliates Agreement may be executed in several counterparts,
each of which shall be deemed to be an original, and all of which shall
constitute one and the same instrument.

    12.  The execution of this Affiliates Agreement is not an admission of the
Shareholder that it is an affiliate of the Company.

    13.  This Affiliates Agreement shall terminate if the Reorganization
Agreement is terminated without the Merger having occurred.

    _______________________________ ("Shareholder") is aware that, pursuant to
that certain Agreement and Plan of Merger and Reorganization (the
"Reorganization Agreement") dated as of September 3, 1997 among INVISION
TECHNOLOGIES, INC., a Delaware corporation ("Parent"), QP ACQUISITION CORP., a
California corporation and a wholly owned subsidiary of Parent ("Merger Sub"),
and QUANTUM MAGNETICS, INC., a California corporation (the "Company"), it is
contemplated that Merger Sub will merge into the Company (the contemplated
merger of Merger Sub into the Company being referred to in this Certificate as
the "Merger").  As a result of the Merger, it is contemplated that holders of
the Common Stock, Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock, in each case with no par value, of the Company (collectively,
the "Company Capital Stock") will receive shares of common stock, par value
$.001 per share, of Parent ("Parent Common Stock") in exchange for their shares
of Company Capital Stock, and that the Company will become a wholly owned
subsidiary of Parent.

    1.   Shareholder represents, warrants and certifies to Parent, Merger Sub
and the Company as follows:

         (a)  Shareholder currently is the "beneficial owner" (as such term is
defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of
_________________ shares of Company Capital Stock (the "Shares"), and did not
acquire any of the Shares in contemplation of the Merger.

         (b)  Shareholder has not engaged in a Sale (as defined below) of any
shares of Company Capital Stock in contemplation of the Merger.

         (c)  Shareholder has no plan or intention to engage in a sale,
exchange, transfer, distribution, redemption or reduction in any way of
Shareholder's risk of ownership (by short sale or otherwise), or other
disposition, directly or indirectly (such actions being collectively referred to
herein as a "Sale"), of more than fifty percent (50%) of the shares of Parent
Common Stock to be received by Shareholder in the Merger.  (For purposes of the
preceding sentence, shares of Company Capital Stock (or the portion thereof)
(i) with respect to which Shareholder will receive consideration in the Merger
other than shares of Parent Common Stock (including, without limitation, cash to
be received in lieu of fractional shares of Parent Common Stock or pursuant to
the exercise of dissenters' rights) and/or (ii) with respect to which a Sale
(A) occurred in contemplation of the Merger or (B) will occur prior to the
Merger, shall be considered shares of Company Capital Stock exchanged for shares
of Parent Common Stock in the Merger and then disposed of pursuant to a plan.)

         (d)  Shareholder has no plan or intention to exercise appraisal rights
in connection with the Merger.


                                          1.


         (e)  Shareholder is not aware of, or participating in, any plan or
intention on the part of the shareholders of the Company to engage in a Sale or
Sales of more than fifty percent (50%) of the shares of Parent Common Stock to
be received in the Merger.  (For purposes of the preceding sentence, shares of
Company Capital Stock (or the portion thereof) (i) with respect to which a
shareholder of the Company receives consideration in the Merger other than
shares of Parent Common Stock (including, without limitation, cash received
pursuant to the exercise of dissenters' rights or in lieu of a fractional share
of Parent Common Stock) and/or (ii) with respect to which a Sale (A) occurred in
contemplation of the Merger or (B) will occur prior to the Merger, shall be
considered shares of outstanding Company Capital Stock exchanged for shares of
Parent Common Stock in the Merger and then disposed of pursuant to a plan.)

         (f)  Except to the extent written notification to the contrary is
received by Parent and the Company from Shareholder prior to the consummation of
the Merger, the representations, warranties and certifications contained herein
shall be accurate at all times from the date hereof through the date on which
the Merger is consummated.

         (g)  Shareholder has consulted with such legal counsel and financial
advisors as he has deemed appropriate in connection with the execution of this
Certificate.

    2.   Shareholder understands and acknowledges that Parent, Merger Sub, the
Company and the Company's shareholders, as well as legal counsel to Parent,
Merger Sub and the Company (in connection with rendering their opinions that the
Merger will be a "reorganization" within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended) will be relying on the accuracy of
the representations, warranties and certifications contained herein.

    Shareholder has executed this Certificate on September __, 1997.

                               NONCOMPETITION AGREEMENT


    This NON-COMPETITION AGREEMENT (the "Agreement") is made this __ day of
September, 1997, by and among INVISION TECHNOLOGIES, INC., a Delaware
corporation ("Parent"), QP ACQUISITION CORP., a California corporation, ("Merger
Sub"), and ____________ ("Shareholder").

                                       RECITALS

    Shareholder is a key employee and shareholder of QUANTUM MAGNETICS, INC., a
California corporation ("the Company").  Parent, Merger Sub and the Company have
entered into an Agreement and Plan of Merger and Reorganization dated as of
September 3, 1997 providing for the acquisition (the "Acquisition") by Parent of
the Company pursuant to a merger of Merger Sub and the Company (the "Merger").
Shareholder plans to vote in favor of the Merger and receive all the benefits of
the Merger and, in connection therewith, Shareholder has agreed pursuant to and
to the extent permitted by Section 16601 of the Business and Professions Code of
the State of California not to compete with the Company in the manner and to the
extent herein set forth.  It is a condition to closing the Merger that
Shareholder execute this Agreement, and Shareholder is entering into this
Agreement as an inducement to Parent and Merger Sub to consummate the Merger,
with all of the attendant financial benefits to Shareholder as a shareholder of
the Company.

                                      AGREEMENT

    NOW, THEREFORE, in consideration of the mutual covenants herein
contemplated and intending to be legally bound hereby, Merger Sub, Parent and
Shareholder agree as follows:

    1.   ACKNOWLEDGEMENTS BY SHAREHOLDER.  Shareholder acknowledges that by
virtue of his/her position with the Company s/he has developed considerable
expertise in the business operations of the Company and has had access to
extensive confidential information with respect to the Company.  Shareholder
recognizes that Merger Sub and Parent would be irreparably damaged, and their
substantial investment in the Company materially impaired, if Shareholder were
to enter into an activity competing with the Company's business in violation of
the terms of this Agreement or if Shareholder were to disclose or make
unauthorized use of any confidential information concerning the business of the
Company.  Accordingly, Shareholder expressly acknowledges that s/he is
voluntarily entering into this Agreement and that the terms and conditions of
this Agreement are fair and reasonable to Shareholder in all respects.

    2.   CONFIDENTIALITY.  Shareholder hereby expressly affirms that the
Quantum Magnetics Employee Proprietary Information and Invention Agreement dated
as of ____________, 19__ (the "Confidentiality Agreement") between the
Shareholder and the Company is and shall remain in full force and effect and
specifically agrees that the rights and privileges of the Company under the
Confidentiality Agreement shall inure to the benefit of


                                          1.


Parent and Merger Sub, to the same extent as if they were original parties
thereto, as well as to the Company.  Further, Shareholder hereby expressly
agrees that the Company's rights under this Agreement are in addition to, but
not in substitution of, its rights under the Confidentiality Agreement and the
Confidentiality Agreement remains in full force and effect.

    3.   NON-COMPETITION.  Until the later of (a) [one (1) year] [three (3)
years] after completion of the Merger or (b) cessation by Parent or the Company
to make salary, consulting fee or severance payments to Shareholder under a
separate agreement or arrangement, if any ("Payment Termination"), Shareholder
shall not, directly or indirectly, without the prior written consent of Parent,
(i) own, manage, operate, join, control, finance or participate in the
ownership, management, operation, control or financing of, or be connected as an
officer, director, employee, partner, principal, agent, representative,
consultant, licensor, licensee or otherwise with, any business or enterprise
engaged in any business which is competitive with the business of the Company,
within each of the geographical units which are listed in Appendix A hereto (the
"Territory"), or (ii) engage in any other manner, within the Territory, in any
business which is competitive with the business of the Company.  For the
purposes of this Section 3, the "business of the Company" shall be defined as
set forth in Appendix B hereto (which also includes a list of companies deemed
by the parties to be in competition with the business of the Company and
therefore covered by the terms of this Noncompetition Agreement).
Notwithstanding the above, Shareholder shall not be deemed to be engaged
directly or indirectly in any business in contravention of subparagraphs (i) or
(ii) above, if (x) Shareholder participates in any such business solely as a
passive investor in up to 1% of the equity securities of a company or
partnership, the securities of which are publicly traded, or (y) Shareholder is
employed by a business or enterprise that is engaged primarily in a business
other than the business of the Company and Shareholder does not apply his
expertise at such business or enterprise to that part of such business or
enterprise that is or could be competitive with the business of the Company.

    4.   NON-INTERFERENCE.  Shareholder further agrees that until the later of
(a) [one (1) year] [three (3) years] years following completion of the Merger or
(b) one (1) year following the Payment Termination, he will not, without the
prior written consent of Parent, (i) interfere with the business of the Company,
Parent or Merger Sub, by soliciting, attempting to solicit, inducing, or
otherwise causing any employee or consultant of the Company, Parent or Merger
Sub to terminate his or her employment as such in order to become an employee,
consultant or independent contractor to or for any competitor of the Company,
Parent or Merger Sub or to or for any company with which Shareholder is
associated in any way; or (ii) induce or attempt to induce any customers,
suppliers, distributors, resellers, or independent contractor of the Company or
Parent to terminate their relationships with, or to take any action that would
be disadvantageous to the business of, the Company or Parent.

    5.   INDEPENDENCE OF OBLIGATIONS.  The covenants of Shareholder set forth
in this Agreement shall be construed as independent of any other agreement or
arrangement between Shareholder, on the one hand, and Merger Sub, the Company or
Parent or any of their subsidiaries, on the other, and the existence of any
claim or cause of action by Shareholder against Merger Sub, the Company or
Parent or any of their subsidiaries shall not constitute a defense to the
enforcement of such covenants against Shareholder.


                                          2.


    6.   EQUITABLE RELIEF.  Shareholder expressly acknowledges that damages
alone will not be an adequate remedy for any breach by Shareholder of the
covenants set forth in Sections 2, 3, and 4 hereof and that the other parties
hereto, in addition to any other remedies which they may have, whether at law,
in equity, by contract or otherwise, shall be entitled, as a matter of right, to
injunctive relief, including specific performance, in any court of competent
jurisdiction with respect to any actual or threatened breach by Shareholder of
any of said covenants.

    7.   SEVERABILITY, ETC.

         a.   If any provision of this Agreement or any part of any such
provision is held under any circumstances to be invalid or unenforceable in any
jurisdiction, then (i) such provision or part thereof shall, with respect to
such circumstances and in such jurisdiction, be deemed amended to conform to
applicable laws so as to be valid and enforceable to the fullest possible
extent, (ii) the invalidity or unenforceability of such provision or part
thereof under such circumstances and in such jurisdiction shall not affect the
validity or enforceability of such provision or part thereof under any other
circumstances or in any other jurisdiction, and (iii) such invalidity of
enforceability of such provision or part thereof shall not affect the validity
or enforceability of the remainder of such provision or the validity or
enforceability of any other provision of this Agreement.  Each provision of this
Agreement is separable from every other provision of this Agreement, and each
part of each provision of this Agreement is separable from every other part of
such provision.

         b.   The parties intend that the covenant contained in Section 3 above
shall be construed as a series of separate covenants, one for each geographical
unit specified.  Except for geographical coverage, each such separate covenant
shall be deemed identical in terms to the covenant contained in Section 3 above.
If, in any judicial proceeding, a court shall refuse to enforce any of the
separate covenants deemed included in this Agreement, then the unenforceable
covenant shall be deemed eliminated from these provisions for the purpose of
those proceedings to the extent necessary to permit the remaining separate
covenants to be enforced.

    8.   NOTICES.  All notices or other communications hereunder shall be in
writing and deemed given if and when delivered to a party in person, or if and
when mailed by registered or certified mail, return receipt requested, to the

                   FORM OF LEGAL OPINION OF BRANTON, WILSON & MUNS

    As used herein, "Merger Agreement" means the agreement of merger to be
filed pursuant to Section 1.3 of the Reorganization Agreement.

    1.   The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of California.  The Company has the
corporate power and authority to own, lease and operate its properties and to
carry on its business as now conducted.

    2.   To the best of such counsel's knowledge, the Company is qualified as a
foreign corporation to do business and is in good standing in each jurisdiction
in the United States in which the ownership of its property or the conduct of
its business requires such qualification and where any statutory fines or
penalties or any corporate disability imposed for the failure to qualify would
materially and adversely affect the Company, its assets, financial condition or
operations.

    3.   Immediately prior to the Closing, the Company's authorized capital
stock consists of (a) 17,000,000 shares of Common Stock, no par value, of which
3,994,216 are issued and outstanding, and (b) 7,911,340 shares of Preferred
Stock, no par value, of which 2,500,000 are designated as Series A Preferred
Stock, 1,666,669 of which are issued and outstanding; of which 711,340 are
designated as Series B Preferred Stock, all of which are issued and outstanding;
of which 3,500,000 are designated as Series C Preferred Stock, 1,643,556 of
which are issued and outstanding; and of which 1,200,000 are designated as
Series D Preferred Stock, 441,328 of which are issued and outstanding.  The
outstanding capital stock of the Company (a) has been duly authorized and
validly issued and is fully paid and nonassessable, (b) is not subject to any
preemptive rights created by statute, or by the Company's Articles of
Incorporation or Bylaws, each as in effect immediately prior to the Effective
Time, or by an agreement to which the Company is a party or may be bound, and
(c) to the best of such counsel's knowledge, are held by the Company's
shareholders free and clear of adverse claims.  To such counsel's knowledge,
other than as set forth in Part 2.3 of the Disclosure Schedule, there are no
options, warrants, calls, rights, commitments, conversion rights or agreements
of any character to which the Company is a party or by which the Company is
bound obligating the Company to issue, deliver or sell, or cause to be issued,
delivered or sold, any shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the Company, or
obligating the Company to grant, extend or enter into any such option, warrant,
call, right, commitment, conversion right or agreement.

    4.   All corporate action, including approval by the Company's Board of
Directors and its shareholders, required to be taken on the part of the Company
to authorize the Company to execute, deliver and perform its obligations under
the Reorganization Agreement, the Merger Agreement and the Escrow Agreement and
to consummate the Merger has been duly and validly taken.


                                          1.


    5.   The Reorganization Agreement, the Merger Agreement and the Escrow
Agreement have been duly and validly authorized, executed and delivered by the
Company and are the valid and binding obligations of the Company enforceable in
accordance with their respective terms, except as the indemnification provisions
contained in Section 9 of the Reorganization Agreement and Section 8.2 of the
Escrow Agreement may be limited by applicable laws and except as may be limited
by applicable bankruptcy, insolvency, reorganization, arrangement, moratorium or
other similar laws affecting creditors' rights, and subject to general equity
principles and to limitations on availability of equitable relief, including
specific performance.

    6.   The execution and delivery of the Reorganization Agreement, the Merger
Agreement and the Escrow Agreement by the Company, and the consummation by the
Company of the transactions contemplated thereby and compliance by the Company
with the provisions thereof, do not violate any provision of the Articles of
Incorporation or the Bylaws of the Company, and do not constitute a material
default under the provisions of any material agreement known to such counsel to
which the Company is a party or by which it is bound, and do not violate or
contravene (a) any governmental statute, rule or regulation applicable to the
Company or (b) any order, writ, judgment, injunction, decree, determination or
award which has been entered against the Company and of which such counsel is
aware.

    7.   No government consent, approval, authorization, registration,
declaration or filing is required for the execution and delivery of the
Reorganization Agreement, the Merger Agreement or the Escrow Agreement on behalf
of the Company or for the performance by the Company of the Merger, except for
(a) the filing of the Merger Agreement with the Secretary of State of the State
of California as contemplated by Section 1.3 of the Reorganization Agreement and
as required by the California General Corporation Law and (b) such government
consents, approvals, authorizations, registrations, declarations and filings as
have been obtained or made.

    8.   To the best of such counsel's knowledge, there is no action,
proceeding or investigation pending or overtly threatened against the Company
before any court or administrative agency that questions the validity of the
Reorganization Agreement, the Merger Agreement or the Escrow Agreement, or,
other than as disclosed in the Disclosure Schedule, that might result, either
individually or in the aggregate, in any material adverse change in the assets,
financial condition, or operations of the Company.

    9.   Upon filing of the Merger Agreement with the Secretary of State of
California, assuming Parent and Merger Sub have complied with all requirements
of applicable law and the Reorganization Agreement and related agreements
necessary to effect the Merger, the Merger will become effective with the effect
stated in the Merger Agreement and Section 1107 of the California General
Corporation Law.

    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

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
limit any of Parent's or any other Indemnitee's rights, or any obligation of the

other agreement entered into in connection with the transactions contemplated by
the Reorganization Agreement.
