                          AGREEMENT AND PLAN OF MERGER


        THIS AGREEMENT AND PLAN OF MERGER is dated as of November 2, 1999 among
QUEST SOFTWARE, INC., a California corporation ("Quest"), QUEST ACQUISITION
CORPORATION, a California corporation and a wholly-owned subsidiary of Quest
("Sub"), MBR TECHNOLOGIES, INC., a California corporation ("MBR"), and JOHN
ROCHA ("Rocha"), JOSEPH F. BRUSATTO ("Brusatto"), MICHAEL Q. MAI ("Mai") and
VICENTE PEREZ DE TUDELA ("Tudela") (individually, a "Shareholder" and
collectively, the "Shareholders").

        INTENDING TO BE LEGALLY BOUND, and in consideration of the premises and
mutual covenants and agreements contained herein, Quest, Sub, MBR, and the
Shareholders hereby agree as follows:

                                    ARTICLE I
                                   THE MERGER

        1.1 Merger; Effective Time of the Merger. Upon the terms and conditions
hereinafter set forth and in accordance with the California General Corporation
Law ("CGCL"), at the Effective Time (as defined in Section 1.3 below), Sub shall
be merged with and into MBR (the "Merger"), and thereupon, the separate
existence of Sub shall cease and MBR, as the Surviving Corporation (as defined
in Section 1.4 below), shall continue to exist under and be governed by the
CGCL.

        1.2 Closing. Subject to the terms and conditions of this Agreement, the
closing of the Merger (the "Closing") shall take place at the offices of
Brobeck, Phleger & Harrison LLP, 38 Technology Drive, Irvine, California 92618,
as promptly as practicable after satisfaction or waiver of the conditions set
forth in Article VI or at such other location, time or date as may be agreed to
in writing by the parties hereto. The date on which the Closing occurs is
hereinafter referred to as the "Closing Date."

        1.3 Effective Time. As soon as practicable after all of the conditions
set forth in Article VI are satisfied or waived, the parties hereto shall cause
an Agreement of Merger (or like instrument) and any other appropriate
documentation ("Agreement of Merger") meeting the requirements of Section 1103
of the CGCL to be properly executed and filed in accordance with the CGCL on the
Closing Date. The Merger shall become effective at the time of acceptance by the
Secretary of State of the State of California of such filing in accordance with
the CGCL, or at such other time which the parties hereto shall have agreed upon
and designated in such filing as the effective time of the Merger (the
"Effective Time").

        1.4 Effect of the Merger. At the Effective Time (i) the separate
existence of Sub shall cease and Sub shall be merged with and into MBR (MBR and
Sub are sometimes referred to herein as the "Constituent Corporations," and MBR,
after giving effect to the Merger, is sometimes referred to herein as the
"Surviving Corporation"); (ii) the Articles of Incorporation of Sub shall be the
Articles of Incorporation of the Surviving Corporation; (iii) the Bylaws of Sub
shall be the Bylaws of the Surviving Corporation; (iv) the directors and
officers of Sub shall be the directors and officers of the Surviving
Corporation; and (v) the Merger shall have all the


                                       1
   7

effects provided by the applicable provisions of the CGCL. Without limiting the
generality of the foregoing, at and after the Effective Time, the Surviving
Corporation shall possess all the rights, privileges, powers and franchises, and
be subject to all the restrictions and duties of each of the Constituent
Corporations.

        1.5 Tax-Free Reorganization. The Merger is intended to be a
reorganization within the meaning of Section 368(a)(1)(A) of the Internal
Revenue Code of 1986, as amended (the "Code").

                                   ARTICLE II
                 EFFECT OF THE MERGER; EXCHANGE OF CERTIFICATES

        2.1 Effect on Common Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of Quest, Sub, MBR, the Shareholders
or any other holder of any capital stock of MBR:

               (a) Conversion of MBR Common Stock. Subject to the terms and
conditions of this Agreement, including, without limitation, the expense
provisions set forth in Section 5.5 hereof and the escrow provisions set forth
in Article VIII hereof, each share of Common Stock of MBR that is issued and
outstanding immediately prior to the Effective Time (the "MBR Common Stock")
(provided that shares of MBR Common Stock, if any, for which the holder has
perfected appraisal rights under Section 1300 of the CGCL ("Dissenting Shares")
shall not be converted into the right to receive any cash or shares of Common
Stock of Quest ("Quest Common Stock") as set forth herein, but shall be
converted into the right to receive such consideration as may be determined to
be due with respect to such Dissenting Shares pursuant to the CGCL) will be
converted, without any required action on the part of the holder thereof, into a
right to receive (i) an amount in cash equal to the quotient obtained by
dividing (A) an amount equal to $1,500,000 (the "Aggregate Cash Payment"), as
adjusted pursuant to Section 2.1(g) below, minus the sum of (v) an amount equal
to the MBR Transaction Expenses (as defined below), plus (w) $45,000, plus (x)
an amount equal to the unpaid principal amount and all accrued interest thereon
under the Promissory Notes (as defined below) as of and including the Closing
Date, plus (y) any Excess Shareholder Loan Amount (as defined in Section 9.1
below), plus (z) any Option Payment Overage by (B) the number of shares of MBR
Common Stock issued and outstanding immediately prior to the Effective Time (the
"Per Share Cash Payment"), and (ii) a fraction of a share of Quest Common Stock
equal to the "Exchange Ratio."

               (b) Exchange Ratio. The Exchange Ratio shall be determined by
dividing

                      (i) the number of shares of Quest Common Stock (the
        "Merger Shares") equal to the quotient obtained by dividing (A)
        $10,000,000 (the "Aggregate Stock Payment"), as adjusted pursuant to
        Section 2.1(g) below, by (B) the Average Price (as defined in Section
        2.1(g) below); by

                      (ii) the number of shares of MBR Common Stock issued and
        outstanding immediately prior to the Effective Time.

        For purposes of this Agreement, "MBR Transaction Expenses" means any and
all costs and expenses of MBR and the Shareholders incurred in connection with
the Merger and this


                                       2
   8

Agreement, including, without limitation, fees and expenses of legal counsel,
financial and business advisors and accountants, and any investment banking and
broker commissions (including, without limitation, the commission and other fees
of Mike Ellington and/or SEG Companies).

        For purposes of this Agreement, "Promissory Notes" means those
Promissory Notes of MBR held by Quest dated October 5, 1999 and October 11,
1999, for $50,000 and $450,000, respectively.

               (c) Stock Options and Warrants. At the Effective Time, all
then-issued and outstanding stock options to purchase MBR Common Stock shall be
cancelled and MBR shall pay each holder of such options an amount per option
share a cash consideration in accordance with the terms of the MBR Fiscal Year
2000 Equity Incentive Plan. At the Closing, Quest shall pay to MBR an amount in
cash equal to the aggregate amount of cash required to pay such cash
consideration not to exceed $100,000. If the aggregate amount of cash required
to pay such cash consideration to the holders of such options exceeds $100,000
(the "Option Payment Overage"), such amount shall reduce, on a dollar-for-dollar
basis, the Aggregate Cash Payment under Section 2.1. At the Effective Time,
except as set forth in Section 6.1(l), all then-issued and outstanding warrants
to acquire shares of MBR Common Stock ("MBR Warrants") shall be exercised in
full. Any MBR Warrants that remain unexercised at the Effective Time shall be
cancelled.

               (d) Adjustments to Per Share Cash Payment and Exchange Ratio. The
Per Share Cash Payment and Exchange Ratio shall be adjusted accordingly to
reflect fully the effect of any stock split, reverse stock split, stock dividend
(including any dividend or distribution of securities convertible into Quest
Common Stock and MBR Common Stock), reorganization, recapitalization or other
like change with respect to Quest Common Stock and MBR Common Stock occurring
after the date of this Agreement and prior to the Effective Time.

               (e) Fractional Shares. No fraction of a share of Quest Common
Stock will be issued by virtue of the Merger, and such fractional share
interests will not entitle the owner thereof to vote or to any rights of a
shareholder of Quest. In lieu of issuing fractional shares, each holder of
shares of MBR Common Stock who would otherwise be entitled to a fraction of a
share of Quest Common Stock (after aggregating all fractional shares of Quest
Common Stock to be received by such holder) shall receive from Quest an amount
of cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) the Average Price.

               (f) Capital Stock of Sub. Each share of Common Stock of Sub
issued and outstanding immediately prior to the Effective Time shall be
converted into and exchanged for one fully-paid and non-assessable share of the
Surviving Corporation's Common Stock.

               (g) Average Price. For purposes of this Agreement, the term
"Average Price" shall mean the per share average of the closing prices of one
share of Quest Common Stock on the NASDAQ National Market for the five trading
days ending one day prior to the Closing Date; provided, that if the Average
Price is less than $35 per share, Quest shall have the right to increase the
Aggregate Cash Payment and reduce the Aggregate Stock Payment on a
dollar-for-dollar basis; provided further, that in no event shall (i) the
aggregate of the Aggregate Cash


                                       3
   9

Payment and Aggregate Stock Payment be less than $11.5 million or (ii) the
amount of the Aggregate Cash Payment (together with any other cash paid to
holders of Dissenting Shares or otherwise considered for purposes of Section
368(a)(2)(D) of the Code), exceed 20% of the total purchase price for MBR in the
Merger.

        2.2 Appraisal Rights.

               (a) Holders of Dissenting Shares who have complied with all
requirements for perfecting the appraisal rights as set forth in Section 1300 of
the CGCL shall be entitled to their rights under such laws as may be agreed to
by such shareholders and MBR or as finally determined by a court of competent
jurisdiction. Each holder of Dissenting Shares who becomes entitled to payment
of the value of shares of stock shall receive payment therefor (but only after
the value therefor shall have been agreed upon or finally determined pursuant to
such provisions).

               (b) Notwithstanding the provisions of subsection 2.2(a), if after
the Effective Time any Dissenting Shares shall lose their status as Dissenting
Shares, such shares shall automatically thereupon be converted into and
represent only the right to receive Quest Common Stock in accordance with
Section 2.1, without interest thereon, less any Escrow Shares required to be set
aside with respect to such Dissenting Shares (that lose their status as such)
pursuant to Article VIII.

               (c) MBR shall give Quest (i) prompt notice of any written demands
for appraisal of any shares of MBR Common Stock, withdrawals of such demands,
and any other instruments served pursuant to the CGCL and received by MBR which
relate to any such demand for appraisal; and (ii) the opportunity to participate
in all negotiations and proceedings which take place prior to the Effective Time
with respect to demands for appraisal under the CGCL. MBR shall not, except with
the prior written consent of Quest, voluntarily make any payment with respect to
any demands for appraisal of MBR Common Stock or offer to settle or settle any
such demands.

        2.3 Surrender of MBR Common Stock Certificates and Delivery of Quest
Common Stock Certificates and Cash.

               (a) Exchange Agent. Prior to the Closing Date, Quest shall
appoint U.S. Stock Transfer Corp. or another similar institution, to act as the
exchange and paying agent (the "Exchange Agent") in the Merger.

               (b) Quest to Provide Common Stock and Cash. Promptly after the
Effective Time, Quest shall make available to the Exchange Agent for exchange in
accordance with this Article II, through such reasonable procedures as Quest may
adopt, the Merger Shares issuable at the Effective Time pursuant to Section 2.1
for the outstanding shares of MBR Common Stock, less such number of shares of
Quest Common Stock as shall be deposited into the Escrow Fund (as defined in
Section 8.1 below) pursuant to the requirements of Article VIII of this
Agreement and cash in an amount sufficient for payment in lieu of fractional
shares pursuant to Section 2.1(e). In addition, on the Closing Date, upon the
terms and subject to the conditions contained in this Agreement, Quest shall pay
to the Exchange Agent for application in



                                       4
   10

accordance with Section 2.1, an amount in immediately available funds equal to
the Aggregate Cash Payment, as adjusted and less the amounts noted in Sections
2.1(a)(i)(A)(v), (w), (x), (y) and (z) above.

               (c) Exchange Procedures for Shares of Quest Common Stock.
Promptly after the Effective Time, Quest shall cause the Exchange Agent to mail
to each holder of record of a certificate or certificates which immediately
prior to the Effective Time represented outstanding shares of MBR Common Stock
(the "Certificates") whose shares were converted into a right to receive shares
of Quest Common Stock and a portion of the Aggregate Cash Payment pursuant to
Section 2.1, (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as Quest may reasonably specify); and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing the appropriate number of shares of Quest
Common Stock and the appropriate portion of the Aggregate Cash Payment. Upon
surrender of a Certificate for cancellation to the Exchange Agent, together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, the holder of such Certificate shall be entitled
to receive, in exchange therefor, a certificate representing the number of whole
shares of Quest Common Stock and the portion of the Aggregate Cash Payment which
such holder has the right to receive pursuant to Section 2.1. The Certificates
so surrendered shall forthwith be canceled. Until so surrendered, each
outstanding Certificate (except a Certificate representing Dissenting Shares, if
any) will be deemed, from and after the Effective Time, to represent solely the
right to receive upon such surrender that number of full shares of Quest Common
Stock and the portion of the Aggregate Cash Payment into which such shares of
MBR Common Stock shall have been so converted and the right to receive an amount
in cash in lieu of the issuance of any fractional shares, both in accordance
with Section 2.1.

               (d) Distributions With Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the date of this
Agreement with respect to Quest Common Stock with a record date after the
Effective Time will be paid to the holder of any unsurrendered Certificate with
respect to the shares of Quest Common Stock represented thereby until the holder
of record of such Certificate shall surrender such Certificate. Subject to
applicable law, following surrender of any such Certificate, there shall be paid
to the record holder of the Certificates representing whole shares of Quest
Common Stock issued in exchange therefor, without interest, at the time of such
surrender, the amount of dividends or other distributions with a record date
after the Effective Time payable with respect to such whole shares of Quest
Common Stock.

               (e) Transfers of Ownership. If any certificate for shares of
Quest Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to Quest or any agent designated by it
any transfer or other taxes required by reason of the issuance of a certificate
for shares of Quest Common Stock in any name other than that of the registered
holder of the Certificate surrendered or established to the satisfaction of
Quest or any agent designated by it that such tax has been paid or is not
payable.

   11

               (f) No Liability. Notwithstanding anything to the contrary in
this Section 2.3, none of the Exchange Agent, the Surviving Corporation or any
party hereto shall be liable to a holder of shares of Quest Common Stock or MBR
Common Stock for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.

        2.4 No Further Ownership Rights in MBR Common Stock. All shares of Quest
Common Stock issued and the Aggregate Cash Payment paid upon the surrender for
exchange of shares of MBR Common Stock in accordance with the terms of Section
2.1 hereof, shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of MBR Common Stock and there shall be no
further registration of transfers on the records of MBR of shares of MBR Common
Stock which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in Section 2.3.

        2.5 Lost, Stolen or Destroyed Certificates. In the event any
Certificates evidencing shares of MBR Common Stock shall have been lost, stolen
or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen
or destroyed Certificates, upon the making of an affidavit of that fact by the
holder thereof, such shares of Quest Common Stock, the appropriate portion of
the Aggregate Cash Payment and cash for fractional shares, if any, as may be
required pursuant to Section 2.1; provided, that Quest may, in its discretion
and as a condition precedent to the issuance thereof, require the owner of such
lost, stolen or destroyed certificates to indemnify Quest against any loss or
cost incurred by or claim that may be made against Quest, the Surviving
Corporation, or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

        2.6 Exemption from Registration; California Permit. The Merger Shares
will be issued in a transaction exempt from registration under the Securities
Act of 1933, as amended (the "Securities Act"), by reason of Section 3(a)(10)
thereof. The Quest Common Stock will be qualified under the California
Securities Law of 1968, pursuant to Section 25121 thereof, after a fairness
hearing has been held pursuant to the authority granted by Section 25142 of such
law. Each of Quest and MBR shall use its commercially reasonable efforts, as
promptly as practicable following the execution and delivery of this Agreement,
to (i) file an application for the issuance of a California permit to issue the
Quest Common Stock and (ii) obtain such permit. All filing fees with respect to
the filing of such application shall be borne and paid by Quest.

                                   ARTICLE III
           REPRESENTATIONS AND WARRANTIES OF MBR AND THE SHAREHOLDERS

        Except as disclosed in the MBR Disclosure Schedule attached hereto (the
"MBR Disclosure Schedule"), MBR and each of the Shareholders, jointly and
severally, represent and warrant to Quest and Sub as set forth below. The MBR
Disclosure Schedule shall be arranged in sections corresponding to the specific
numbered and lettered Section contained in this Agreement.

        3.1 Corporate Existence, Good Standing and Authority. MBR is a
corporation duly organized, validly existing and in good standing under the laws
of the State of California. MBR has full corporate power and corporate authority
to carry on its business as now being conducted




                                       6
   12

and is entitled to own, lease or operate the property and assets now owned,
leased or operated by it, and has no operations or employees and conducts no
business outside of the States or Countries listed in Section 3.1 of the MBR
Disclosure Schedule. MBR is qualified to do business, is in good standing and
has all required and appropriate licenses in each jurisdiction in which its
failure to obtain or maintain such qualification, good standing or licensing (i)
would, individually or in the aggregate, have, or reasonably could be expected
to have, a material adverse effect on the assets, liabilities, business,
financial condition, results of operations, or prospects of MBR (a "Material
Adverse Effect") or (ii) would result in a material breach of any of the other
representations, warranties or covenants set forth in this Agreement. MBR has
all requisite corporate power and authority to enter into this Agreement and all
agreements and other documents to be entered into in connection herewith and to
consummate the transactions contemplated hereby. All corporate action on the
part of MBR and its respective directors and shareholders, necessary for the
authorization, execution, delivery and performance of this Agreement and all
other agreements to be entered into in connection herewith by MBR, and the
performance of the respective obligations of MBR and the Shareholders hereunder
and thereunder has been taken or will be taken prior to the Closing Date. This
Agreement and all agreements and other documents to be entered into in
connection herewith have been duly executed and delivered by MBR and the
Shareholders and constitute legal, valid and binding obligations of MBR and each
of the Shareholders, enforceable against MBR and each of the Shareholders in
accordance with its terms, except as such enforceability may be limited by
principles of public policy and subject to the laws of general application
relating to bankruptcy, insolvency and the relief of debtors and rules of law
governing specific performance, injunctive relief or other equitable remedies.

        3.2 Capitalization.

               (a) The authorized capital stock of MBR consists of 10,000,000
shares of Common Stock, no par value per share, of which 1,025,000 shares are
issued and outstanding. All of the MBR Common Stock is owned, beneficially and
of record, only by the shareholders listed in Section 3.2(a) of the MBR
Disclosure Schedule, which lists the names, addresses and number of shares held.
All of the outstanding MBR Common Stock has been duly authorized, validly issued
and is fully paid and nonassessable and, as of the Closing Date, will be issued
in compliance with all federal and state securities laws (including, without
limitation, any filing, notice, qualification or registration requirements with
any federal or state authority). Other than as described in Section 3.2(a) of
the MBR Disclosure Schedule, there are no options, warrants, calls, conversion
rights, rights of exchange, or other rights, plans, agreements or commitments of
any nature whatsoever (including, without limitation, conversion or preemptive
rights), written or oral, providing for the purchase, issuance, sale or pledge
of any shares of capital stock of MBR or any securities convertible into or
exchangeable for any shares of capital stock of MBR ("MBR Rights"). Section
3.2(a) of the MBR Disclosure Schedule also contains a schedule listing each
holder of an MBR Right and the number of rights held by such holder. Except as
set forth in Section 3.2(a) of the MBR Disclosure Schedule, there are no
obligations, contingent or otherwise, of MBR to repurchase, redeem or otherwise
acquire any shares of MBR Common Stock or make any investment (in the form of a
loan, capital contribution or otherwise) in any other entity. Section 3.2(a) of
the MBR Disclosure Schedule will be updated immediately prior to Closing to
reflect the conversion of all MBR Rights into MBR Common Stock.



                                       7
   13

               (b) Except as set forth in Section 3.2(b) of the MBR Disclosure
Schedule, MBR is not in active discussion, formal or informal, with any person
or entity regarding the issuance of any form of additional MBR equity or MBR
Right. Except as provided in this Agreement, there are no voting trusts, proxies
or other agreements or understandings with respect to the voting of the MBR
Common Stock.

        3.3 Subsidiaries. Except as set forth in Section 3.3 of the MBR
Disclosure Schedule, MBR has never been a subsidiary of any other entity and
does not currently own, nor has it ever owned, directly or indirectly, any
interest in any other corporation, association, joint venture or other business
entity. MBR does not control, directly or indirectly, the management or policies
of any other corporation, association, joint venture or other business entity.

        3.4 Financial Statements. The financial statements which include the
balance sheet and related results of operations and statement of shareholders'
equity and cash flows of MBR at and for its fiscal year ended March 31, 1999
(audited) (the "Financial Statements") and an internally generated income
statement and balance sheet at and for the 6-month period ended September 30,
1999 (unaudited) (the "Interim Information") are attached to Section 3.4 of the
MBR Disclosure Schedule. The internal books and records of MBR from which the

accordance with generally accepted accounting principles in the United States
("GAAP"), applied on a consistent basis throughout the periods presented; and
(iii) present fairly the financial position and results of operations of MBR at
the dates and for the periods reflected therein. The Interim Information (i) was
prepared in accordance with such books and records; and (ii) presents fairly the
financial position and results of operations of MBR at the dates and for the
periods reflected therein. The reserves set forth in the Financial Statements
are adequate for MBR's business in light of the contingencies with respect to
which they were established.

        3.5 Absence of Certain Changes. Since March 31, 1999, except as set
forth in the Interim Information or Section 3.5 of the MBR Disclosure Schedule

limitation period applicable to any claim or assessment in respect of taxes with
any taxing authority or otherwise;

               (s) The commencement of any legal or administrative action or
proceeding by MBR or the commencement of any legal or administrative action or

               (t) Any agreement or commitment by MBR to do any of the things

               (u) To the knowledge of MBR and the Shareholders, any fact or

        3.6 Properties. MBR does not own or hold title to any real property.
With respect to the property and assets it leases, MBR is in compliance with
such leases and holds a valid leasehold interest in such property and assets
free of any liens, claims or encumbrances of any kind whatsoever (except for
liens for taxes not yet due). There is set forth in Section 3.6 of the MBR
Disclosure Schedule: (i) a list of all leases or rental contracts under which
MBR is a lessee, lessor, sublessee or sublessor; and (ii) a list of all
equipment used by MBR in the operation of its business which is owned or leased
by MBR and which had an original cost of $25,000 or more. MBR has beneficial
ownership of and good and marketable title to, or sufficient rights to use for
the purposes of the business of MBR, all properties and assets used in its
operations or necessary for the conduct of its business, and the properties and
assets owned by MBR are subject to no mortgages, liens, pledges, loans or
encumbrances of any kind whatsoever, except for the loans from Quest evidenced
by the Promissory Notes (as defined in Section 5.3), the liens created by the
Security Agreement between MBR and Quest dated October 5, 1999 and liens for
taxes not yet due. All real and tangible personal property, including machinery,
equipment and fixtures currently used by MBR in the operation of its business
is, and at the time of Closing will be, in good operating condition and repair,
ordinary wear and tear excepted, and are adequate and suitable for the purposes
for which they are currently being used. All improvements on leased property
used by MBR in the operation of its business and the current use thereof are in
accordance with all applicable laws and the agreements under which such
improvements are leased. The value of any fixed asset used by MBR in the
operation of its business has not been



                                       10
   16

written up or down, other than pursuant to depreciation or amortization expenses
in accordance with GAAP, applied on a consistent basis.

        3.7 Accounts Receivable. Section 3.7 of the MBR Disclosure Schedule
contains (i) a complete and accurate list of the accounts and notes receivable
in excess of $1,000 of MBR as of the date of this Agreement (which Section of
the MBR Disclosure Schedule will be updated immediately prior to Closing); and
(ii) a complete and accurate schedule showing the aging of such accounts and
notes receivable. Such accounts and notes receivables arose in bona-fide, arms
length transactions in the normal course of MBR's business and, to the knowledge
of MBR and the Shareholders, such accounts and notes receivable (A) are and will
be at the Closing valid and binding obligations of the account debtors without
counterclaims, set-offs or other defenses thereto and (B) are (except to the
extent of the reserves thereon as set forth in the Financial Statements)
collectible in the ordinary course of business. The values at which accounts and
notes receivable are carried on the books and records of MBR reflect the
receivables valuation policy of MBR which is consistent with its past practice
and in accordance with GAAP, applied on a consistent basis.

        3.8 Indebtedness. Section 3.8 of the MBR Disclosure Schedule contains a
complete list of each and every agreement or other instrument under or pursuant
to which MBR has outstanding indebtedness for borrowed money. MBR has furnished
Quest with true and correct copies of each such agreement and instrument,
including all amendments with respect thereto through the date of this
Agreement. MBR is not in default under any such agreement or instrument and, to
the knowledge of MBR and the Shareholders, no other party to any such agreement
or instrument is in default under any such agreement or instrument.

        3.9 Litigation. No litigation, arbitration or other judicial or
regulatory proceeding is pending or, to the knowledge of MBR and the
Shareholders, threatened by or against MBR, its properties or assets, the MBR
Common Stock or the officers or directors of MBR (in their capacity as such)
before any court or any government agency, foreign or domestic, and, to the
knowledge of MBR and the Shareholders, no facts exist which would reasonably be
expected to form the basis for any such litigation, arbitration or proceeding.
To the knowledge of MBR and the Shareholders, MBR is not the subject of any
investigation for violation of any laws, regulations or administrative orders
applicable to its business by any governmental authority or any other person,
and, to the knowledge of MBR and the Shareholders, no facts exist which would
reasonably be expected to form the basis for any such investigation. There is no
judgment, writ, decree, injunction, rule or order of any court, governmental
department, commission, agency, instrumentality or arbitrator outstanding
against MBR, its properties, intellectual property rights or assets or the MBR
Common Stock.

        3.10 No Breach. The execution and delivery of this Agreement and the
other agreements to be entered into in connection herewith, the consummation of
the transactions and government hearing contemplated by this Agreement and such
other agreements and Quest's operation of the business of MBR following the
Closing in a manner consistent with the conduct of such operations prior to the
Closing will not result in or constitute any of the following: (i) a conflict,
violation or default with or an event that, with notice or lapse of time or
both, would be a default, breach, or violation of the Articles of Incorporation
or Bylaws of MBR, any Permits (as defined in Section 3.13), any Contracts (as
defined in Section 3.13); (ii) an event that would




                                       11
   17

permit any party to terminate any agreement or to accelerate the maturity of or
permit the subordination of any right of MBR; (iii) the creation or imposition
of any lien, charge, interest, or encumbrance on any of the assets of MBR or the
MBR Common Stock; or (iv) conflict with or result in the violation or breach of
any law, rule or regulation of any governmental authority, or any judgment,
order, injunction or decree applicable to MBR, its intellectual property rights,
assets or the MBR Common Stock.

        3.11 Employees and Employee Benefit Plans.

               (a) Section 3.11 of the MBR Disclosure Schedule contains a list
of each labor and employment agreement to which MBR is a party or by which it is
bound, employee benefit program, arrangement, contract, and plan (including,
without limitation, any employment, consulting agreement consulting agreements
providing for annual compensation in excess of $25,000, severance, deferred
compensation, bonus, stock option, stock purchase, phantom stock, stock
appreciation, and "employee benefit plan," as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974 ("ERISA") currently maintained
or contributed to by MBR or any MBR subsidiary or other trade or business
(whether or not incorporated) treated as a single employer with MBR pursuant to
Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986 (the
"Code") is a party (a "MBR ERISA Affiliate"), or with respect to which MBR or
any MBR ERISA Affiliate could incur liability under Section 4069, 4212(c) or
4204 of ERISA or Section 412 of the Code (the "MBR Benefit Plans").

               (b) With respect to each MBR Benefit Plan, MBR has delivered or
made available to Quest a true, complete and correct copy of (i) such MBR
Benefit Plan document(s) and the most recent summary plan description related to
such MBR Benefit Plan, if a summary plan description is required therefor; (ii)
each trust agreement or other funding arrangement relating to such MBR Benefit
Plan; (iii) the most recent annual report (Form 5500), filed with the Internal
Revenue Service ("IRS") with respect to such MBR Benefit Plan; (iv) the most
recent actuarial report or financial statement relating to such MBR Benefit
Plan; (v) the most recent actual deferral percentage test and actual
contribution percentage test; and (vi) the most recent determination letter
issued by the IRS with respect to such MBR Benefit Plan, if it is qualified
under Section 401(a) of the Code. Neither MBR nor any MBR Affiliate has any
express or implied commitment, whether legally enforceable or not, to modify,
change or terminate any MBR Benefit Plan, other than with respect to a
modification, change or termination required by ERISA or the Code.

               (c) Each MBR Benefit Plan has been administered in all material
respects in accordance with its terms, and all contributions required to be made
under the terms of any of the MBR Benefit Plans of the date of this Agreement
and the Closing Date have been or will be timely made or have been reflected on
the most recent consolidated balance sheet filed or incorporated by reference in
the MBR Benefit Plans prior to the date of this Agreement. With respect to the
MBR Benefit Plans, no event has occurred and, to the knowledge of MBR and the
Shareholders, there exists no condition or set of circumstances in connection
with which MBR or any MBR ERISA Affiliate could be subject to any liability
under the terms of such MBR Benefit Plans, ERISA, the Code or any other
applicable law which could reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect on MBR or the Surviving Corporation.



                                       12
   18

               (d) MBR on behalf of itself and all of the MBR ERISA Affiliates
hereby represents that, except in those instances where the failure of such
representation to be true could not reasonably be expected to have, individually
or in the aggregate, a Material Adverse Effect on MBR or the Surviving
Corporation: (i) each MBR Benefit Plan which is intended to be qualified under
Section 401(a) of the Code or Section 401(k) of the Code has received a
favorable determination letter from the IRS as to its qualified status under the
Code, including, without limitation, its qualification under the Tax Reform Act
of 1986, and each trust established in connection with any MBR Benefit Plan
which is intended to be exempt from federal income taxation under Section 501(a)
of the Code has received a determination letter from the IRS that it is so
exempt, and to MBR's and the Shareholders' knowledge no fact or event has
occurred since the date of such determination letter from the IRS to adversely
affect the qualified status of any such MBR Benefit Plan or the exempt status of
any such trust; (ii) to MBR's and the Shareholders' knowledge there has been no
prohibited transaction (within the meaning of Section 406 of ERISA or Section
4975 of the Code) with respect to any MBR Benefit Plan; (iii) no reportable
event (within the meaning of Section 4043 of ERISA) has occurred or is expected
to occur with respect to any MBR Benefit Plan subject to Title IV of ERISA; (iv)
no MBR Benefit Plan had an accumulated funding deficiency (within the meaning of
Section 302 of ERISA or Section 412 of the Code), whether or not waived, as of
the most recently ended plan year of such MBR Benefit Plan; (v) none of the
assets of MBR or any MBR ERISA Affiliate is the subject of any lien arising
under Section 302(f) of ERISA or Section 412(n) of the Code, and no MBR Benefit
Plan which is subject to Title IV of ERISA has an "unfunded benefit liability"
(within the meaning of Section 4001(a)(18) of ERISA); and (vi) each MBR Benefit
Plan can be amended, terminated or otherwise discontinued after the Effective
Time in accordance with its terms, without liability (other than ordinary
administrative expenses typically incurred in a termination event). No suit,
administrative proceeding, action or other litigation has been brought, or to
the knowledge of MBR and the Shareholders is threatened, against or with respect
to any such MBR Benefit Plan, including any audit or inquiry by the Internal
Revenue Service or United States Department of Labor (other than routine
benefits claims).

               (e) No payment or benefit which will be made by MBR or any MBR
ERISA Affiliate under any MBR Benefit Plan will constitute an excess parachute
payment under Code Section 280(G)(1), and the consummation of the transactions
contemplated by this Agreement will not (i) entitle any current or former
employee or other service provider of MBR or any MBR ERISA Affiliate to
severance benefits or any other payment, except as expressly provided by this
Agreement; or (ii) accelerate the time of payment or vesting, or increase the
amount of compensation due any such employee or service provider. As of
September 30, 1999, there were accrued sales commissions of approximately $8,500
under the MBR Commission Plan A, Fiscal Year 1999 (the "1999 Commission Plan").
The 1999 Commission Plan is terminable at any time by MBR. Upon termination of
the MBR employees and the 1999 Commission Plan by MBR effective as of the
Effective Time, there will not be any continuing obligation of Quest or the
Surviving Corporation thereunder other than commissions that were accrued
through the Effective Time.

               (f) MBR is not a party to any collective bargaining or other
labor union contract applicable to persons employed by MBR and no collective
bargaining agreement is being negotiated by MBR. As of the date of this
Agreement, there is no labor dispute, strike or work stoppage against MBR
pending or, to the knowledge of MBR or the Shareholders, threatened




                                       13
   19

which may interfere with the respective business activities of MBR, except where
such dispute, strike or work stoppage could not reasonably be expected to have a
Material Adverse Effect on MBR or the Surviving Corporation. As of the date of

the Merger is consummated, shall be pending which, in the good faith judgment of
MBR's or Quest's Board of Directors (acting upon the written opinion of outside
counsel) has a reasonable probability of resulting in such order, injunction or
relief and such relief would have a Material Adverse Effect on Quest or the

such injunction lifted.

quotation on the Nasdaq National Market.

                        (ii) by Quest (provided Quest is not in material breach
                of this Agreement), if there has been a breach by MBR or the
                Shareholders of any representation, warranty, covenant or
                agreement set forth in this Agreement on the part of MBR or the
                Shareholders which is material and which MBR or the Shareholders
                fail to cure within 10

   40

                business days after notice thereof is given by Quest (except
                that no cure period shall be provided for a breach by MBR or the
                Shareholders which by its nature cannot be cured);

                        (iii) by Quest if the Board of Directors of MBR amends,
                withholds or withdraws its recommendation of the Merger
                (provided Quest is not in material breach of this Agreement);

                        (iv) by MBR (provided MBR is not in material breach of
                this Agreement), if there has been a breach by Quest or Sub of

                which Quest or Sub, as the case may be, fails to cure within 10
                business days after notice thereof is given by MBR (except that
                no cure period shall be provided for a breach by Quest or Sub

                reason of the failure of any condition precedent under Section
                6.1 and 6.2 (unless the failure results primarily from a breach
                by Quest of any representation, warranty, or covenant of Quest
                contained in this Agreement or Quest's failure to fulfill a
                condition precedent to Closing or other default);

                        (vi) by MBR, by giving written notice to Quest, if the
                Closing shall not have occurred on or before January 5, 2000 by
                reason of the failure of any condition precedent under Section
                6.1 and 6.3 (unless the failure results primarily from a breach
                by MBR or the Shareholders of any representation, warranty, or
                covenant of MBR or the Shareholders contained in this Agreement
                or MBR's or the Shareholders' failure to fulfill a condition
                precedent to Closing or other default); or

                        (vii) by Quest or MBR if (A) any permanent injunction or
                other order of a court or other competent authority preventing
                the Merger shall have become final and nonappealable; or (B)
                there shall be any final action taken, or any statute, rule,
                regulation or order enacted, promulgated or issued or deemed
                applicable to the Merger by any governmental entity which would
                make consummation of the Merger illegal or which would prohibit
                Quest or the Surviving Corporation's ownership or operation of
                all or a material portion of the business of MBR, or compel
                Quest or the Surviving Corporation to dispose of or hold
                separate all or a material portion of the business or assets of
                MBR or Quest or the Surviving Corporation as a result of the
                Merger.

               (b) Where action is taken to terminate this Agreement pursuant to
this Section 7.1, it shall be sufficient for such action to be authorized by the
Board of Directors of the party authorized to take such action.

this Section 7.1, all obligations of the parties hereunder shall terminate

of any party for breach of this Agreement); provided, that the agreements
contained in Sections 5.3, 5.5, 5.6, 7.1(c), 10.7, 10.8, 10.13, 10.14 and 10.15
hereof shall survive.

                                  ARTICLE VIII
                         INDEMNIFICATION AND ESCROW FUND

        8.1 Indemnity and Escrow Fund. The Shareholders shall indemnify and hold
harmless Quest and the Surviving Corporation in respect of any and all Damages
(as defined below) that Quest or the Surviving Corporation incur by reason of
any Indemnifiable Items (as defined below). To secure performance of such
indemnification obligations, as soon as practicable after the Effective Time,
10% of the Merger Shares (the "Escrow Shares") shall be deposited with and
registered in the name of Quest as escrow agent (the "Escrow Agent"), such
deposit to constitute the escrow fund (the "Escrow Fund") and to be governed by
the terms set forth herein and in the Escrow Agreement attached hereto as
Exhibit 5.7. The Escrow Fund shall be available to compensate Quest and the
Surviving Corporation for any loss, expense, liability or other damage,
including, without limitation, reasonable attorneys' fees, accountants' fees,
and all other reasonable costs and expenses of litigation, investigation,
defense or settlement of claims (including costs of all appeals related thereto)
or threats thereof and amounts paid in settlement to the extent of the amount of
such loss, expense, liability or other damage (collectively, "Damages") that
Quest and the Surviving Corporation incur by reason of (i) the breach by MBR or
any Shareholder of any representation, warranty, covenant or agreement of MBR or
any Shareholder contained herein; and (ii) any of the matters set forth in
Exhibit 8.1 hereto (collectively, (i) and (ii) shall be referred to as
"Indemnifiable Items"). Nothing contained in this Article VIII shall limit the
liability (i) of MBR or any Shareholder for any breach of any representation,
warranty or covenant if the Merger does not close; or (ii) of any Shareholder in
connection with any breach by such Shareholder of the Voting Agreement.

        8.2 Escrow Period. The Escrow Period shall terminate at the expiration
of 12 months following the Closing Date; provided, that a portion of the Escrow
Fund, which, in the reasonable judgment of Quest, subject to the objection of
the Shareholders' Agent (defined in Section 8.6 below) and the subsequent
resolution or arbitration of the matter in the manner provided in Section 8.5,
is necessary to satisfy any unsatisfied claims specified in any Officer's
Certificate (as defined in Section 8.3(a) below) theretofore delivered to the
Escrow Agent prior to termination of the Escrow Period with respect to facts and
circumstances existing prior to expiration of the Escrow Period, shall remain in
the Escrow Fund until such claims have been resolved.

        8.3 Claims Upon Escrow Fund.

               (a) Upon receipt by the Escrow Agent on or before the last day of
the Escrow Period of a certificate of Quest (an "Officer's Certificate")
specifying in reasonable detail the individual items of such Damages included in
the amount so stated, the date each such item was paid, or properly accrued or
arose, the nature of the Indemnifiable Item which such item is related, the
Escrow Agent shall, subject to the provisions of Section 8.4 hereof, deliver to
Quest out of the Escrow Fund, as promptly as practicable, Quest Common Stock or
other assets held in the Escrow Fund having a value equal to such Damages.

               (b) For the purpose of compensating Quest for its Damages from
the Escrow Fund, the Quest Common Stock in the Escrow Fund shall be valued at
the average of the closing prices of the Common Stock of Quest, as reported by
the Nasdaq National Market over the




                                       36
   42

period of five trading days ending on the trading day preceding the date on
which the Quest Common Stock is delivered by the Escrow Agent to Quest.

        8.4 Objections to Claims. At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such Officer's Certificate
shall be delivered to the Shareholders' Agent and for a period of 15 days after
such delivery, the Escrow Agent shall make no delivery of Quest Common Stock or
other property pursuant to Section 8.3 hereof unless the Escrow Agent shall have
received written authorization from the Shareholders' Agent to make such
delivery. After the expiration of such 15-day period, the Escrow Agent shall
make delivery of the Quest Common Stock or other property in the Escrow Fund in
accordance with Section 8.3 hereof; provided, that no such payment or delivery
may be made if the Shareholders' Agent shall object in a written statement to
the claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent and to Quest prior to the expiration of such
15-day period.

        8.5 Attempt to Resolve Conflicts; Arbitration.

               (a) In case the Shareholders' Agent shall so object in writing to
any claim or claims by Quest made in any Officer's Certificate or otherwise,
Quest shall have 30 days to respond in a written statement to the objection of
the Shareholders' Agent. If after such 30-day period there remains a dispute as
to any claims, the Shareholders' Agent and Quest shall attempt in good faith for
30 days to agree upon the rights of the respective parties with respect to each
of such claims. If the Shareholders' Agent and Quest should so agree, a
memorandum setting forth such agreement shall be prepared and signed by both
parties and shall, if a claim is being made against the Escrow Fund, be
furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any
such memorandum and shall distribute the Quest Common Stock or other property
from the Escrow Fund in accordance with the terms thereof.

               (b) If no such agreement can be reached after good faith
negotiation, either Quest or the Shareholders' Agent may, by written notice to
the other, demand binding arbitration of the matter unless the Damages are at
issue in pending litigation with a third party. If the Damages are at issue in
pending litigation, then the arbitration shall not be commenced until such
amount is ascertained or both parties agree to arbitration; and in either such
event the matter shall be settled by arbitration conducted by three arbitrators.
Within 15 days after such written notice is sent, Quest and the Shareholders'
Agent shall each select one arbitrator, and the two arbitrators so selected
shall select a third arbitrator. The decision of the arbitrators as to the
validity and amount of any claim in such Officer's Certificate shall be binding
and conclusive upon the parties to this Agreement, and the Escrow Agent shall be
entitled to act in accordance with such decision and make or withhold payments
out of the Escrow Fund in accordance therewith.

               (c) Any such arbitration shall be held in the County of Orange,
California under the commercial rules then in effect of the American Arbitration
Association. The parties hereto agree that any action to compel arbitration
pursuant to this Agreement may be brought in any appropriate court in the County
of Orange, California and in connection with such action to compel the laws of
the State of California to control. Application may also be made to such court
for confirmation of any decision or award of the arbitrator, for an order of the
enforcement and for any other remedies which may be necessary to effectuate such
decision or award. The




                                       37
   43

parties hereto hereby consent to the jurisdiction of the arbitrator and of such
court and waive any objection to the jurisdiction of such arbitrator and court.

               (d) If a dispute is submitted for arbitration as provided in this
Section 8.5, the Escrow Agent shall continue to hold Escrow Shares in the Escrow
Fund having a value sufficient to cover the Damages related to such dispute (the
"Contested Damages") (but only to the extent that there are Escrow Shares
remaining in the Escrow Fund) until: (i) delivery of a copy of a settlement
agreement executed by Quest and the Shareholders' Agent setting forth
instructions to the Escrow Agent as to the release of such Escrow Shares that
shall be made with respect to the Contested Damages; (ii) delivery of a copy of
the final decision of the arbitrators setting forth instructions to the Escrow
Agent as to the release of Escrow Shares that shall be made with respect to the
Contested Damages; or (iii) receipt of a court order or judgment directing the
Escrow Agent to act with respect to the distribution of any Escrow Shares. The
Escrow Agent shall thereupon release the Escrow Shares from the Escrow Fund (to
the extent Escrow Shares are then held in the Escrow Fund) in accordance with
such settlement agreement, arbitrator's instructions, court order or judgment,
as applicable. If any controversy arises involving any party to this Agreement
(other than the Escrow Agent) concerning the subject matter of this Agreement,
including Contested Damages, the Escrow Agent will not be required to resolve
the controversy.

        8.6 Shareholders' Agent.

               (a) Rocha shall be constituted and appointed as agent
("Shareholders' Agent") for and on behalf of the MBR shareholders to give and
receive notices and communications, to authorize delivery to Quest of the Quest
Common Stock or other property from the Escrow Fund in satisfaction of claims by
Quest, to settle any other claims for indemnification, to object to such
deliveries, to agree to, negotiate, enter into settlements and compromises of,
and demand arbitration and comply with orders of courts and awards of
arbitrators with respect to such claims, and to take all actions necessary or
appropriate in the judgment of the Shareholders' Agent for the accomplishment of
the foregoing. Such agency may be changed by the holders of a majority in
interest of the Escrow Fund from time to time upon not less than 10 days' prior
written notice to Quest. No bond shall be required of the Shareholders' Agent,
and the Shareholders' Agent shall receive no compensation for his services.
Notices or communications to or from the Shareholders' Agent shall constitute
notice to or from each of the MBR shareholders.

               (b) The Shareholders' Agent shall not be liable for any act done
or omitted hereunder as Shareholders' Agent while acting in good faith and in
the exercise of reasonable judgment, and any act done or omitted pursuant to the
advice of counsel shall be conclusive evidence of such good faith. The MBR
shareholders shall severally indemnify the Shareholders' Agent and hold him
harmless against any loss, liability or expense incurred without gross
negligence or bad faith on the part of the Shareholders' Agent and arising out
of or in connection with the acceptance or administration of his duties
hereunder.

               (c) The Shareholders' Agent shall have reasonable access to
information about MBR and the reasonable assistance of MBR's officers and
employees for purposes of performing its duties and exercising its rights
hereunder; provided, that the Shareholders' Agent




                                       38
   44

shall treat confidentially and not disclose any nonpublic information from or
about MBR to anyone (except on a need to know basis to individuals who agree to
treat such information confidentially).

        8.7 Actions of the Shareholders' Agent. A decision, act, consent or
instruction of the Shareholders' Agent shall constitute a decision of all MBR
shareholders for whom shares of Quest Common Stock otherwise issuable to them
are deposited in the Escrow Fund and shall be final, binding and conclusive upon
each such MBR shareholder, and the Escrow Agent and Quest may rely upon any
decision, act, consent or instruction of the Shareholders' Agent as being the
decision, act, consent or instruction of each and every such MBR shareholder.
The Escrow Agent and Quest are hereby relieved from any liability to any person
for any acts done by them in accordance with such decision, act, consent or
instruction of the Shareholders' Agent.

        8.8 Third-Party Claims. In the event that a third party asserts or
threatens a claim which Quest believes may result in a demand against the Escrow
Fund, Quest shall notify the Shareholders' Agent of such claim, and the
Shareholders' Agent on behalf of the MBR shareholders for whom shares of Quest
Common Stock otherwise issuable or payable to them are deposited in the Escrow
Fund shall be entitled, at such shareholders' expense, to participate in any
defense of such claim. Unless the Shareholder's Agent elects to assume such
defense (with counsel reasonably acceptable to Quest, and, provided, that the
Shareholder's Agent has the reasonable means to put on such a defense), Quest
shall have the right to settle any such claim (with its own counsel); provided,
that Quest may not effect the settlement of any such claim without the consent
of the Shareholders' Agent, which consent shall not be unreasonably withheld. In
the event that the Shareholders' Agent has consented to any such settlement, the
Shareholders' Agent and the former MBR shareholders shall have no power or
authority to object under Section 8.4 or any other provision of this Article
VIII to the amount of any claim by Quest against the Escrow Fund for indemnity
with respect to such settlement.

        8.9 Limitations.

               (a) Notwithstanding anything else set forth herein, Quest and the
Surviving Corporation may not receive any Escrow Shares from the Escrow Fund and
shall not otherwise be entitled to any indemnification under this Article VIII
unless and until an Officer's Certificate or Certificates identifying Damages of
at least an amount equal to the sum of $75,000, in the aggregate for any and all
claims for Damages has or have been delivered to the Escrow Agent and
Shareholders' Agent as provided in Sections 8.3 and 8.4, in which case Quest
shall be entitled to receive Escrow Shares equal in value to the full amount of
any and all Damages exceeding $75,000.

               (b) Notwithstanding anything else set forth herein, Quest and the
Surviving Corporation shall not be compensated from the Escrow Fund or otherwise
in respect of any Damages that are covered by insurance proceeds from insurance
owned by MBR and paid for by the Shareholders prior to the Effective Time to the
extent that Quest and/or such other persons actually receive such insurance
proceeds to cover such Damages from such insurance (including all costs and
expenses incurred in pursuing and collecting such insurance proceeds).

   45

               (c) The parties hereto understand and agree that the indemnity
obligations of the Shareholders under this Article VIII shall terminate 12
months from the Closing Date, except (i) insofar as a claim for indemnification
under this Article VIII has been asserted and such claim has not been resolved
in accordance with the terms of the this Agreement, the Escrow Agreement or
otherwise, or (ii) for any Damages incurred by Quest or the Surviving
Corporation as a result of a breach of the representations and warranties set
forth in Sections 3.2 (Capitalization) and 3.25 (Taxes), in which case the
indemnity obligations shall terminate upon the expiration of the relevant
statute of limitations. No Shareholder shall be personally liable under this
Article VIII for any Damages beyond the consideration received by such
Shareholder under this Agreement (as such consideration may be reduced by
federal and state income taxes imposed). In the event that any payment by a
Shareholder to Quest is actually reduced by virtue of a reduction in maximum
aggregate liability caused by the imposition of federal or state income taxes,
the Shareholder shall deliver a promissory note to Quest in the amount of such
actual payment reduction containing the following terms: (i) the promissory note
will be a non-recourse obligation of such Shareholder, payable only if and to
the extent that such Shareholder derives a tax benefit from the payment of its
liability under this Article VIII; (ii) the promissory note will have a
principal amount equal to the amount of the payment reduction and will bear
interest at the overpayment rate established under Section 6621 of the Internal
Revenue Code of 1986, as amended, and (iii) the promissory note will have a
final maturity of 10 years but will provide for mandatory prepayments at the
time Shareholder derives a tax benefit from the payment of its liability under
this Article VIII. Each Shareholder agrees to seek a refund and otherwise use
any loss or deduction arising from such payment so as to maximize the amount of
its tax benefit. Furthermore, Quest shall be entitled to review any tax return
making a refund claim, current use or carryforward of any such loss or
deduction, and to assume the conduct of any contest involving a dispute over
such a claim, current use or carryforward for claims.

               (d) Nothing herein shall limit Quest's or the Surviving
Corporation's rights to seek recourse against any person or entity for claims

                    holder of such Certificate shall be entitled to receive, in
                    exchange therefor, a certificate representing the number of
                    whole shares of Quest Common Stock and the portion of the
                    Aggregate Cash Payment which such holder has the right to
                    receive pursuant to Section 2.1. The Certificates so
                    surrendered to Quest shall forthwith be canceled. Until so
                    surrendered, each outstanding Certificate (except a
                    Certificate representing Dissenting Shares, if any) will be
                    deemed, from and after the Effective Time, to represent
                    solely the right to receive upon such surrender that number
                    of full shares of Quest Common Stock and the portion of the
                    Aggregate Cash Payment into which such shares of MBR Common
                    Stock shall have been so converted and the right to receive
                    an amount in cash in lieu of the issuance of any fractional
                    shares, both in accordance with Section 2.1.

                    (b) Issuance of Quest Common Stock and Payment of Aggregate
                    Cash Payment. Promptly after the Effective Time, Quest shall
                    instruct U.S. Stock Transfer Corporation to issue to each
                    MBR shareholder the appropriate number of shares of Quest
                    Common Stock issuable pursuant to Section 2.1 for the shares
                    of MBR Common Stock delivered pursuant to Section 2.3(a),
                    less the applicable number of shares of Quest Common Stock
                    to be deposited into the Escrow Fund (as defined in Section
                    8.1 below) pursuant to the requirements of Article VIII of
                    this Agreement and cash in an amount sufficient for payment
                    in lieu of fractional shares pursuant to Section 2.1(d). In
                    addition, on the Closing Date, upon the terms and subject to
                    the conditions contained in this Agreement, in accordance
                    with Section 2.1, Quest shall pay to each holder of a
                    Certificate an amount in immediately available funds equal
                    to the product of (i) the number of shares of MBR Common
                    Stock delivered by such holder and (ii) the Per Share Cash
                    Payment.

                    (c) Distributions With Respect to Unexchanged Shares. No
                    dividends or other distributions declared or made after the
                    date of this Agreement with respect to Quest Common Stock
                    with a record date after the Effective Time will be paid to
                    the holder of any unsurrendered Certificate with respect to
                    the shares of Quest Common Stock represented thereby until
                    the holder of record of such Certificate shall surrender
                    such Certificate.

   55

                    Subject to applicable law, following surrender of any such
                    Certificate, there shall be paid to the record holder of the
                    Certificates representing whole shares of Quest Common Stock
                    issued in exchange therefor, without interest, at the time
                    of such surrender, the amount of dividends or other
                    distributions with a record date after the Effective Time
                    payable with respect to such whole shares of Quest Common
                    Stock.

                    (d) Transfers of Ownership. If any certificate for shares of
                    Quest Common Stock is to be issued in a name other than that
                    in which the Certificate surrendered in exchange therefor is
                    registered, it will be a condition of the issuance thereof
                    that the Certificate so surrendered will be properly
                    endorsed and otherwise in proper form for transfer and that
                    the person requesting such exchange will have paid to Quest
                    or any agent designated by it any transfer or other taxes
                    required by reason of the issuance of a certificate for
                    shares of Quest Common Stock in any name other than that of
                    the registered holder of the Certificate surrendered or
                    established to the satisfaction of Quest or any agent
                    designated by it that such tax has been paid or is not
                    payable.

                    (e) No Liability. Notwithstanding anything to the contrary
                    in this Section 2.3, none of U.S. Stock Transfer
                    Corporation, the Surviving Corporation or any party hereto
                    shall be liable to a holder of shares of Quest Common Stock
                    or MBR Common Stock for any amount properly paid to a public
                    official pursuant to any applicable abandoned property,
                    escheat or similar law."

     3.5. The first sentence of Section 4.1 is hereby deleted and replaced by
          the following:

                    "Each of Quest and Sub is a corporation duly organized and
                    validly existing under and is in good standing under the
                    laws of the States of California and Delaware, respectively.

     force and effect.

     accordance with the laws of the State of California without regard to the
