ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

        On January 7, 2000, Quest Software, Inc. ("Quest") acquired all of the
outstanding shares of Foglight Software, Inc. ("Foglight"), a Delaware
corporation (the "Acquisition"). The Acquisition was consummated pursuant to an
Agreement and Plan of Merger by and among Quest, Quest Acquisition Corporation
II, Inc., a Delaware corporation and the wholly-owned subsidiary of Quest
("Sub"), and Foglight, dated as of November 10, 1999, as amended by that certain
Amendment No. 1 to Agreement and Plan of Merger dated as of December 7, 1999 (as
amended, the "Merger Agreement"). Under the Merger Agreement, Sub was merged
with and into Foglight, and Foglight was the surviving corporation in the merger
and became a wholly-owned subsidiary of Quest. Quest issued an aggregate of
1,187,719 shares of common stock, and paid $11,568.33 in cash, net of reductions
for certain liabilities, in exchange for all of the outstanding stock and
options of Foglight.

        118,772 shares of the total number of shares of Quest common stock
issued to the former Foglight stockholders (the "Escrow Shares") were placed in
a nine-month escrow account as security for the indemnification obligations set
forth in the Merger Agreement. In general, pursuant to the Merger Agreement and
the related escrow agreement, Quest may recover from the escrow for any loses,
expenses, liabilities or other damages due to a breach of any representation,
warranty, covenant or agreement of Foglight in the Merger Agreement and for
certain other enumerated items.

         INTENDING TO BE LEGALLY BOUND, and in consideration of the premises and
mutual covenants and agreements contained herein, Quest, Sub and Foglight 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 Delaware General Corporation
Law ("DGCL"), at the Effective Time (as defined in Section 1.3 below), Sub shall
be merged with and into Foglight (the "Merger"), and thereupon, the separate
existence of Sub shall cease and Foglight, as the Surviving Corporation (as
defined in Section 1.4 below), shall continue to exist under and be governed by
the DGCL.

         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,

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
a Certificate of Merger (or like instrument) and any other appropriate
documentation ("Certificates of Merger") meeting the requirements of Section 252
of the DGCL to be properly executed and filed in accordance with the DGCL on the
Closing Date. The Merger shall become effective at the time of acceptance by the

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

Incorporation of Sub shall be the Certificate of Incorporation of the Surviving
Corporation; (iii) the Bylaws of Sub shall be the Bylaws of the Surviving

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 Capital Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of Quest, Sub and Foglight or any
holder of any capital stock of Foglight:

             (a) Conversion of Foglight Capital 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 Section 2.7 and Article VIII hereof, each share of Preferred Stock of
Foglight ("Foglight Preferred Stock") and each share of Common Stock of Foglight
("Foglight Common Stock") that is issued and outstanding immediately prior to
the Effective Time (the Foglight Preferred Stock and Foglight Common Stock are
collectively referred to herein as the "Foglight Capital Stock") will be
converted, without any required action on the part of the holder thereof, into a
right to receive a fraction of a share of Quest Common Stock (the Common Stock
of Quest shall be referred to herein as the "Quest Common Stock") equal to the
"Exchange Ratio"; provided, that shares of Foglight Capital Stock, if any, for
which the holder has perfected appraisal rights under Section 262 of the DGCL
("Dissenting Shares") shall not be converted into the right to receive any
shares of Quest Common Stock, 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 applicable provisions of the DGCL.

             (b) Exchange Ratio. In the event that every share of Foglight
Preferred Stock has been converted into Foglight Common Stock as of the
Effective Time, the "Exchange Ratio" shall be determined by dividing

                 (i) a number of shares of Quest Common Stock equal to (A) the
         Aggregate Number of Quest Shares (as defined below) less (B) the
         aggregate number of shares of Quest Common Stock equal to the quotient
         obtained by dividing (1) an amount equal to the sum of any Excess
         Liabilities (as defined below), plus any Excess Transaction Expenses
         (as defined below), plus one-half of any outstanding principal and
         accrued and unpaid interest under that certain Promissory Note held by
         Capital Technologies Integration Inc. dated March 16, 1998 in the
         aggregate principal amount of $1,500,000, plus $556,000, by (2) the
         Average Share Price (as defined in Section 2.1(g) below) (the number of
         shares determined pursuant to this clause (b)(i) shall be referred to
         as the "Quest Merger Shares"); by

                 (ii) the sum of (A) the total number of shares of Foglight
         Capital Stock issued and outstanding at the Effective Time, plus (B)
         the number of shares of Foglight


                                       2

<PAGE>   7

         Capital Stock that are issuable upon exercise for cash of all stock
         options, warrants and any other rights to purchase Foglight Capital
         Stock issued and outstanding immediately prior to the Effective Time,
         whether or not such options, warrants or other rights are then
         exercisable.

                 In the event that any shares of Foglight Preferred Stock have
         not been converted into Foglight Common Stock as of the Effective Time,

                 (a) the "Exchange Ratio" applicable to each share of Foglight
         Preferred Stock shall be determined as follows:

                     (1) for each share of Foglight Series A Preferred Stock
                 only, the Exchange Ratio shall equal that fraction of a share
                 of Quest Common Stock that is equivalent in value, based on the
                 closing price per share of Quest Common Stock on the Nasdaq
                 National Market for the 30-day period ending three days prior
                 to the Closing Date, to $1.040188 per share;

                     (2) for each share of Foglight Series B Preferred Stock
                 only, the Exchange Ratio shall equal that fraction of a share
                 of Quest Common Stock that is equivalent in value, based on the
                 closing price per share of Quest Common Stock on the Nasdaq
                 National Market for the 30-day period ending three days prior
                 to the Closing Date, to $3.23 per share; and

                     (3) for each share of Foglight Series C Preferred Stock
                 only, the Exchange Ratio shall equal that fraction of a share
                 of Quest Common Stock that is equivalent in value, based on the
                 closing price per share of Quest Common Stock on the Nasdaq
                 National Market for the 30-day period ending three days prior
                 to the Closing Date, to $2.6667 per share.

                 If the Quest Merger Shares shall be insufficient to permit the
         payment to holders of the Foglight Preferred Stock of their full
         preferential amounts described in this subsection (A), then, prior to
         and in preference to any distribution of the Quest Merger Shares to
         holders of Foglight Common Stock, all of the Quest Merger Shares shall
         be distributed ratably among the holders of the Foglight Preferred
         Stock based on the applicable preferential amounts described in this
         subsection (A).

                 (b) If there are any Quest Merger Shares remaining after the
         payment to the holders of the Foglight Preferred Stock of their full
         preferential amounts described above in Section 2.1(b)(A), then, for
         each share of Foglight Common Stock only, the "Exchange Ratio" shall
         equal

                     (1) that number of remaining Quest Merger Shares (after the
                 payment of the preferential amounts for the Foglight Preferred
                 Stock) divided by;

                     (2) the sum of (a) the total number of shares of Foglight
                 Common Stock issued and outstanding at the Effective Time, plus
                 (2) the number of shares of Foglight Common Stock that are
                 issuable upon exercise for cash of all stock options, warrants
                 and any other rights to purchase Foglight Common Stock issued


                                       3


<PAGE>   8

                 and outstanding immediately prior to the Effective Time,
                 whether or not such options, warrants or other rights are then
                 exercisable.

         For purposes of this Agreement:

         "Aggregate Number of Quest Shares" means a number of shares of Quest
Common Stock, determined as follows:

                     (i) if the Average Share Price is greater than $60.00 and
                 less than $80.00, the Aggregate Number of Quest Shares shall be
                 equal to 1,300,000 shares of Quest Common Stock (the "Base
                 Number");

                     (ii) if the Average Share Price is greater than or equal to
                 $40.00 and less than or equal to $60.00, the Aggregate Number
                 of Quest Shares shall be equal to the sum of (A) the Base
                 Number plus (B) a number of shares of Quest Common Stock equal
                 to the product of (1) $60.00 minus the Average Share Price and
                 (2) 5,000;

                     (iii) if the Average Share Price is less than $40.00, the

                 $80.00 and less than or equal to $100.00, the Aggregate Number
                 of Quest Shares shall be equal to the difference between (A)
                 the Base Number minus (B) an amount equal to the product of (1)
                 the Average Share Price minus $80.00 and (2) 5,000; and

                     (v) if the Average Share Price is greater than $100.00, the
                 Aggregate Number of Quest Shares shall be equal to 1,200,000.

         "Excess Liabilities" means any and all liabilities for borrowed money
and capital lease obligations of Foglight in excess of $3.5 million existing as

outstanding principal and accrued and unpaid interest under the Promissory Notes

referred to in the line items on the September 30, 1999 Balance Sheet as

Common Stock and Foglight Capital Stock occurring after the date of this
Agreement and prior to the Effective Time.

             (f) 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 Foglight
Capital 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

by (ii) the Average Share Price.

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).


                                       5


<PAGE>   10

             (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) Foglight shall give Quest (i) prompt notice of any written
demands for appraisal of any shares of Foglight Capital Stock, withdrawals of
such demands, and any other instruments served pursuant to the DGCL and received
by Foglight 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
DGCL. Foglight shall not, except with the prior written consent of Quest,
voluntarily make any payment with respect to any demands for appraisal of
Foglight Capital Stock or offer to settle or settle any such demands.

         2.3 Surrender of Foglight Capital Stock Certificates and Delivery of
Quest Common Stock Certificates.

             (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. 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 Foglight Capital 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).

             (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 Foglight Capital Stock (the
"Certificates") whose shares were converted into a right to receive shares of
Quest Common Stock 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. 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 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


                                       6


<PAGE>   11

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
into which such shares of Foglight Capital 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.

             (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 Foglight
Capital 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 Foglight Capital Stock. All shares
of Quest Common Stock issued upon the surrender for exchange of shares of
Foglight Capital 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 Foglight Capital Stock and there shall be no further registration
of transfers on the records of Foglight of shares of Foglight Capital 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 Foglight Capital 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 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,


                                       7


<PAGE>   12

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 Foglight 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 Quest Common Stock and (ii) obtain such permit. All filing fees with
respect to the filing of such application shall be borne and paid equally by
Foglight and Quest.

         2.7 Escrow Agreement. At the Effective Time, Quest will, on behalf of
the holders of Foglight Capital Stock, deposit into escrow certificates
representing a total of ten percent of the Aggregate Number of Quest Shares (the
"Escrow Shares"). Such shares will be held in escrow on behalf of the persons
who are the holders of Foglight Capital Stock immediately prior to the Effective
Time (collectively, the "Former Foglight Stockholders"), on a pro rata basis, in
accordance with each such Former Foglight Stockholder's percentage ownership of
Foglight Capital Stock immediately prior to the Effective Time ("Pro Rata
Portion"). The Escrow Shares shall be held as security for the Former Foglight
Stockholders' indemnification obligation under Article VIII hereof. All fees and
expenses related to the escrow, including, without limitation, the fees and
expenses of the Escrow Agent (as defined in Section 8.1 below), shall be paid
and borne equally by Foglight and Quest.

                                  ARTICLE III
                   REPRESENTATIONS AND WARRANTIES OF FOGLIGHT

         Except as disclosed in the Foglight Disclosure Schedule attached hereto
(the "Foglight Disclosure Schedule"), Foglight represents and warrants to Quest
and Sub as set forth below. The Foglight Disclosure Schedule shall be arranged
in sections corresponding to the specific numbered and lettered Section
contained in this Agreement that it relates to. Applicable information so
disclosed with specificity on the Foglight Disclosure Schedule shall be deemed
to be disclosed under and incorporated into any other Section of this Article
III relating to the same subject matter with the understanding that Foglight
shall use its best efforts to include such information or provide
cross-references in the Foglight Disclosure Schedule wherever information is
called for under more than one Section of this Article III. Notwithstanding the
foregoing, the mere listing by name and date of a contract or other agreement or
the mere attachment of an agreement or other document by Foglight on or to the
Foglight Disclosure Schedule shall not be deemed an exception to any Section of
this Agreement unless a specific reference is included in the Foglight
Disclosure Schedule to the particular provision in such agreement or document
that gives rise to the exception to any Section of this Agreement.

         3.1 Corporate Existence, Good Standing and Authority. Foglight is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware.


                                       8


<PAGE>   13

Foglight has full corporate power and corporate authority to carry on its
business as now being conducted 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 Foglight Disclosure Schedule. Foglight 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 would, individually or in the aggregate, have, or
reasonably could be expected to have, a Material Adverse Effect (as defined
below). Foglight 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 Foglight and its respective directors and
Stockholders, necessary for the authorization, execution, delivery and
performance of this Agreement and all other agreements to be entered into in
connection herewith by Foglight, and the performance of the respective
obligations of Foglight 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 Foglight and constitute legal, valid and binding obligations of Foglight,
enforceable against Foglight 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. In this Agreement, any reference to a "Material
Adverse Effect" with respect to any entity or group of entities means any event,
change or effect that, when taken individually or together with all other
adverse changes and effects, is or is reasonably likely to be materially adverse
to the condition (financial or otherwise), properties, assets, liabilities,
business, operations, results of operations or prospects of such entity and its
subsidiaries and other affiliates, taken as a whole; provided, that any change
or effect that results directly from the announcement of the Merger with Quest
shall not be deemed to constitute a Material Adverse Effect.

shares held by each stockholder. All of the outstanding Foglight Capital Stock
has been duly authorized, validly issued and is fully paid and nonassessable and
was 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 Foglight 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, granted or issued

into or exchangeable for any shares of Foglight Capital Stock (collectively,
"Foglight Rights"). Section 3.2(a) of the Foglight Disclosure Schedule also
contains a schedule listing each holder of a Foglight Right granted or issued by
Foglight, the number of rights held by such holder and the number of shares
reserved under all stock incentive plans of Foglight. All Foglight Rights issued
or granted by Foglight were issued in compliance with all applicable federal and
state securities laws. Except as set forth in Section 3.2(a) of the Foglight
Disclosure Schedule, there are no obligations, contingent or otherwise, of
Foglight to repurchase, redeem or otherwise acquire any shares of Foglight
Capital Stock or make any investment (in the form of a loan, capital
contribution or otherwise) in any other entity. An updated Section 3.2(a) of the
Foglight Disclosure Schedule reflecting the changes permitted by this Agreement
between the date hereof and the Effective Time shall be delivered by Foglight to
Quest on the Closing Date.

             (b) Except as set forth in Section 3.2(b) of the Foglight
Disclosure Schedule, Foglight is not in active discussion, formal or informal,
with any person or entity regarding the issuance of any form of additional

defined in Section 3.34), to Foglight's knowledge, there are no voting trusts,
proxies or other agreements or understandings with respect to the voting of the
Foglight Capital Stock.

             (c) Except as set forth in Section 3.2(c) of the Foglight
Disclosure Schedule, all Foglight Stock Options (as defined in Section 5.12)
have been issued in accordance with the terms of the Foglight Option Plan (as
defined in Section 5.12) and pursuant to the standard forms of option agreement
previously provided to Quest or its representatives. Except as set forth in
Section 3.2(c) of the Foglight Disclosure Schedule, neither the consummation of
the transactions contemplated by this Agreement nor any action taken by Foglight
in connection with such transactions will result in (i) any acceleration of
vesting in favor of any optionee under any Foglight Stock Option; (ii) any
additional benefits for any optionee under any Foglight Stock Option; or (iii)
the inability of Quest after the Effective Time to exercise any right or benefit
held by Foglight prior to the Effective Time with respect to any Foglight Stock
Option assumed by Quest, including, without limitation, the right to repurchase
an optionee's shares on termination of such optionee's employment. The
assumption by Quest of Foglight Stock Options in accordance with Section 5.12
hereunder will not constitute a breach of the Foglight Option Plan or any
agreement entered into pursuant to such plan.

         3.3 Subsidiaries. Except as set forth in Section 3.3 of the Foglight
Disclosure Schedule, Foglight 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. Foglight does not control, directly or indirectly, the management or
policies of any other corporation, association, joint venture or other business
entity.

<PAGE>   17

             (u) To the knowledge of Foglight, any fact or circumstance that
will or could reasonably be expected to cause the reserves set forth in the
Financial Statements to be inadequate.

         3.6 Properties. Foglight does not own or hold title to any real
property. With respect to the property and assets it leases, Foglight is in
compliance with such leases in all material respects and holds a valid leasehold
interest in such property and assets free of any liens, claims or encumbrances
of any kind whatsoever. There is set forth in Section 3.6 of the Foglight
Disclosure Schedule: (i) a list of all leases or rental contracts under which
Foglight is a lessee, lessor, sublessee or sublessor; and (ii) a list of all
equipment used by Foglight in the operation of its business which is owned or
leased by Foglight and which had an original cost of $25,000 or more. Foglight
has beneficial ownership of and good and marketable title to all properties and
assets that it owns and that are used in its operations or necessary for the
conduct of its business, and such properties and assets are subject to no
mortgages, liens, pledges, loans or encumbrances of any kind whatsoever, except
for the loan from Quest evidenced by the Promissory Note (as defined in Section
5.3) and the liens created by the Security Agreement between Foglight and Quest
dated October 20, 1999. All real and tangible personal property, including
machinery, equipment and fixtures currently used by Foglight 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 presently being used. All improvements on leased
property used by Foglight in the operation of its business and the present 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
Foglight in the operation of its business has not been 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 Foglight Disclosure
Schedule contains (i) a complete and accurate list of the accounts and notes
receivable of Foglight as of the date of this Agreement (which Section of the
Foglight 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 Foglight's business and such
accounts and notes receivable (A) to Foglight's knowledge, 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 amount carried for doubtful
accounts and allowances set forth in the Financial Statements is sufficient. The
values at which accounts and notes receivable are carried on the books and
records of Foglight reflect the receivables valuation policy of Foglight 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 Foglight Disclosure Schedule
contains a complete list of each and every agreement or other instrument under
or pursuant to which Foglight has outstanding indebtedness for borrowed money.
Foglight 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. Foglight is not in default under any such


                                       13

<PAGE>   18

agreement or instrument and, to Foglight's knowledge, 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 Foglight, threatened by
or against Foglight, its properties or assets, the Foglight Capital Stock or the
officers or directors of Foglight before any court or any government agency,
foreign or domestic, except such as could not have a Material Adverse Effect,
and, to the knowledge of Foglight, no facts exist which might form the basis for
any such litigation, arbitration or proceeding. To Foglight's knowledge,
Foglight 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 Foglight,
no facts exist which might 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 Foglight, its properties, intellectual property rights or assets or the
Foglight Capital 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 Foglight 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 Certificate of
Incorporation or Bylaws of Foglight, any Permits (as defined in Section 3.13),
any Contracts (as defined in Section 3.13); (ii) an event that would permit any
party to terminate any material agreement or to accelerate the maturity of or
permit the subordination of any right of Foglight; (iii) the creation or
imposition of any lien, charge, interest, or encumbrance on any of the assets of
Foglight or the Foglight Capital Stock; or (iv) conflict with or result in the

authority, or any judgment, order, injunction or decree applicable to Foglight,
its intellectual property rights, assets or the Foglight Capital Stock, except
in all cases of (iii) and (iv) above, for conflicts, violations or breaches that
could not result in a Material Adverse Effect.

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") maintained or

(the "Code") is a party (a "Foglight ERISA Affiliate"), or with respect to which
Foglight or any Foglight ERISA Affiliate could incur liability under Section
4069, 4212(c) or 4204 of ERISA or Section 412 of the Code (the "Foglight Benefit
Plans").

<PAGE>   19

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

              (c) Each Foglight 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 Foglight 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 Foglight Benefit Plans prior to the date of
this Agreement. With respect to the Foglight Benefit Plans, no event has
occurred and, to the knowledge of Foglight, there exists no condition or set of
circumstances in connection with which Foglight or any Foglight ERISA Affiliate
could be subject to any liability under the terms of such Foglight 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
Foglight or the Surviving Corporation.

              (d) Foglight on behalf of itself and all of the Foglight 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 Foglight or the
Surviving Corporation: (i) except as set forth in Section 3.11(d) of the
Foglight Disclosure Schedule, each Foglight 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
Foglight 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 (or the time for making application for a
determination letter and remedial amendments with respect to such Foglight
Benefit Plan under Code Section 401(b) has not expired), and to Foglight's
knowledge no fact or event has occurred which may reasonably be expected to
cause the failure of such qualification or the exempt status of any such trust;
(ii) to Foglight's 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 Foglight 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
Foglight Benefit Plan subject to Title IV of ERISA; (iv) no Foglight 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 Foglight Benefit Plan; (v) none of the assets
of Foglight or any Foglight ERISA Affiliate is the


                                       15

<PAGE>   20

subject of any lien arising under Section 302(f) of ERISA or Section 412(n) of
the Code, and no Foglight 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 Foglight 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 or as set forth in an administrative services
contract with respect to such plan). No suit, administrative proceeding, action
or other litigation has been brought, or to the knowledge of Foglight is
threatened, against or with respect to any such Foglight Benefit Plan, including
any audit or inquiry by the Internal Revenue Service or United States Department
of Labor (other than routine benefits claims).

              (e) Except as set forth in Section 3.11(e) of the Foglight
Disclosure Schedule, no payment or benefit which will be made by Foglight or any
Foglight ERISA Affiliate under any Foglight 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 Foglight or any Foglight 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
(except as required under Code Section 4.11(d)(3)).

              (f) Foglight is not a party to any collective bargaining or other
labor union contract applicable to persons employed by Foglight and no
collective bargaining agreement is being negotiated by Foglight. As of the date
of this Agreement, there is no labor dispute, strike or work stoppage against
Foglight pending or, to the knowledge of Foglight or the Stockholders,
threatened which may interfere with the respective business activities of
Foglight, except where such dispute, strike or work stoppage could not
reasonably be expected to have a Material Adverse Effect on Foglight or the
Surviving Corporation. As of the date of this Agreement, to the knowledge of
Foglight, none of Foglight or any of their respective representatives or
employees has committed any unfair labor practice in connection with the
operation of the respective businesses of Foglight, and there is no charge or
complaint against Foglight by the National Labor Relations Board or any
comparable Governmental Entity pending or threatened in writing, except where
such unfair labor practice, charge or complaint could not reasonably be expected
to have a Material Adverse Effect on Foglight or the Surviving Corporation.

              (g) Except as required by law, no Foglight Benefit Plan provides
any of the following retiree benefits to any person: medical, disability or life
insurance benefits. To Foglight's knowledge, Foglight and the Foglight ERISA
Affiliates are in compliance with (i) the requirements of the applicable health
care continuation and notice provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and the regulations (including proposed
regulations) thereunder; and (ii) the applicable requirements of the Health
Insurance Portability and Accountability Act of 1996 and the regulations
(including the proposed regulations) thereunder, except to the extent that such
non-compliance would not reasonably be expected to have, either individually or
in the aggregate, a Material Adverse Effect on Foglight or the Surviving
Corporation.

              (h) Foglight is not involved in any labor discussion with any unit
or group seeking to become the bargaining unit for any of employees of Foglight,

employment agreements and other material agreements concluded with individual
employees to which Foglight is a party; and (ii) independent contractor or
consulting agreements with independent contractors or consultants performing
services in connection with the development of Foglight's products and services.

state tax laws, laws applicable to employee benefits and other applicable law.
All salaries and wages paid by Foglight are in compliance in all material
respects with applicable federal, state and local laws.

         3.12 Insurance. There is set forth in Section 3.12 of the Foglight

insurance of any nature whatsoever maintained by Foglight pertaining to the
business of Foglight, showing, among other things, the amount of coverage, the
company issuing the policy, the expiration date of each policy and the amount of
any premiums thereunder which are due and payable. Such policies are in full
force and effect and such policies, or other policies covering the same risks,
have been in full force and effect, without gaps, continuously since the dates
of their purchase. True and correct copies of all current insurance policies of
Foglight have been made available to Quest for inspection. Foglight is not in
default under any of such policies, and Foglight has not failed to give any
notice or to present any claim under any such policy in a due and timely
fashion. Foglight is not aware of any facts concerning Foglight or its business,
operations, assets and liabilities, contingent or otherwise, upon which an
insurer might be justified in reducing coverage or increasing premiums on
existing policies and all such insurance policies can be maintained in full
force and effect without substantial increase in premium or reducing the
coverage thereof following the Closing. There is no claim pending under any of
such policies as to which coverage has been questioned, denied or disputed by
the underwriters of such policy.

other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interests of Foglight or that would conflict with
Foglight's business as currently proposed to be conducted. Neither the execution
nor delivery of this Agreement, nor the carrying on of Foglight's business by
the employees of Foglight, nor the conduct of Foglight's business as currently

Agreement dated January 13, 1999, reflecting the right to purchase up to 5,289

unvested. Each Foglight Stock Option so assumed by Quest shall continue to have,
and be subject to, the same terms and conditions set forth in the agreement
evidencing such option immediately prior to the Effective Time, except that (i)
such Foglight Stock Option shall be exercisable (when vested) solely and
exclusively for that number of whole shares of Quest Common Stock equal to the
product of the number of shares of Foglight Common Stock that were issuable upon
the exercise of the Foglight Stock Option immediately prior to the Effective
Time, multiplied by the Exchange Ratio and rounded down to the nearest whole
number of shares of Quest Common Stock, (ii) the per share exercise price
payable upon the exercise of such assumed Foglight Stock Option shall be equal

consideration upon the exercise of the assumed Foglight Stock Option. Unless
otherwise agreed to in writing by Quest, there shall be no acceleration of the
vesting of any Foglight Stock Option that is assumed in connection with this
Section 5.12. Quest shall make such assumption in such manner that (i) Quest is
a corporation "assuming a stock option in a transaction to which Section 424(a)
applies" within the meaning of Section 424 of the Code or (ii) to the extent
that Section 424 of the Code does not apply to such Foglight Stock Option, Quest
would be such a corporation were Section 424 of the Code applicable to such
Foglight Stock Option; and, after the Effective Time, all references to Foglight
in any Foglight Option Plan and the applicable stock option agreements shall be
deemed to refer to Quest as issuer and Quest as the employer of the holders of
Foglight Stock Options, as applicable.

             (b) Within 30 days after the Effective Time, Quest shall issue to
each holder of an outstanding Foglight Stock Option a document evidencing the
foregoing assumption of such Foglight Stock Option by Quest.

             (c) Quest shall file a registration statement on Form S-8 for the
shares of Quest Common Stock issuable with respect to assumed Foglight Stock
Options no later than 30 days after the Effective Date.

become employed by Quest from and after the Effective Time as provided in this
Section 5.17(a) shall be referred to herein as "Affected Employees." Nothing
contained herein shall be construed or deemed to limit the ability of either
Foglight or Quest or any other entity from terminating the employment either
before or after the Effective Time of any such Affected Employee.

             (b) Each Affected Employee will be eligible to participate in the
benefit programs, plans, arrangements, payroll practices (including vacation or
paid time off entitlement) offered to similarly situated employees by Quest (the
"Quest Employee Benefit Plans") pursuant to the terms of each such Quest
Employee Benefit Plan, or in the absence of a written plan, in accordance with
the regularly established policies or procedures of Quest.

             (c) Quest will recognize the employment service of each Affected
Employee with Foglight prior to the Effective Time for purposes of eligibility
(but not benefit accrual or vesting) under any Quest Employee Benefit Plan.

             (d) Quest will grant options to purchase up to 235,000 shares of
Quest Common Stock to the Affected Employees within 90 days of the Closing Date

other terms of the Affected Employee Options, including, without limitation,
whether such Options will be issued under the Quest 1999 Stock Incentive Plan,
shall be determined by Quest in its sole discretion.

injunction, or seeking relief against Foglight or Quest if the Merger is
consummated, shall be pending which, in the good faith judgment of Foglight'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. In the event any
such order or injunction shall have been issued, each party agrees to use its
best efforts to have any such injunction lifted.

             (c) Approvals. All authorizations, consents, orders or approvals
of, or declarations or filings with, or expiration of waiting periods imposed
by, any governmental entity necessary for the consummation of the transactions
contemplated by this Agreement shall have been filed, occurred or been obtained,
other than filings and approvals relating to the Merger or affecting Quest's
ownership of Foglight or any of its properties if failure to make such filing or
obtain such approval would not be materially adverse to Quest or Foglight.

             (d) Nasdaq. The shares of Quest Common Stock to be issued in the
Merger shall have been approved for quotation on the Nasdaq National Market.

             (e) Tax Opinions. Quest and Foglight shall each have received a
written opinion from its respective counsel dated as of the Closing Date to the
effect that the Merger will


                                       36

be treated for Federal income tax purposes as a "reorganization" within the

rendering such opinion.

             (f) California Permit. The shares of Quest Common Stock to be

                                  TERMINATION

         7.1 Termination.

             (a) This Agreement may be terminated at any time prior to the
Effective Time:

                 (i) by mutual written agreement of Quest and Foglight;

                 (ii) by Quest (provided Quest is not in material breach of this
         Agreement), if there has been a breach by Foglight of any
         representation, warranty, covenant or agreement set forth in this

<PAGE>   44

                 (iv) by Foglight (provided Foglight is not in material breach
         of this Agreement), if there has been a breach by Quest or Sub of any
         representation, warranty, covenant or agreement set forth in this
         Agreement on the part of Quest or Sub which is material and which Quest
         or Sub, as the case may be, fails to cure within ten business days
         after notice thereof is given by Foglight (except that no cure period
         shall be provided for a breach by Quest or Sub which by its nature
         cannot be cured);

                 (v) by Quest, by giving written notice to Foglight, if the
         Closing shall not have occurred on or before January 31, 1999 by 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);

         representation, warranty, or covenant of Foglight contained in this
         Agreement or Foglight's failure to fulfill a condition precedent to
         Closing or other default); or

                 (vii) by Quest or Foglight if (A) any permanent injunction or
         other order of a court or other competent authority preventing the

         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's or the Surviving Corporation's
         ownership or operation of all or a material portion of the business of
         Foglight, or compel Quest or the Surviving Corporation to dispose of or
         hold separate all or a material portion of the business or assets of
         Foglight 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.

         (c) If either Quest or Foglight terminates this Agreement pursuant to
this Section 7.1, all obligations of the parties hereunder shall terminate
without any liability of any party to any other party (except for any liability
of any party for breach of this Agreement); provided, that the agreements
contained in Sections 5.5, 5.6, 7.1(c), 9.7, 9.8, 9.13, 9.14 and 9.15 hereof
shall survive.

                                  ARTICLE VIII
                         INDEMNIFICATION AND ESCROW FUND

         8.1 Indemnity and Escrow Fund. From and after the Effective Time and
subject to the limitations contained in this Article VIII, the Former Foglight
Stockholders will, severally and pro rata, in accordance with their Pro Rata
Portion, 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, the Escrow Shares shall be deposited with and
registered in the name of an escrow agent reasonably acceptable to Foglight and
Quest (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. 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 or alleged
breach by Foglight of any representation, warranty, covenant or agreement of
Foglight 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
Foglight for any breach of any representation, warranty or covenant if the
Closing is not consummated; or (ii) of any stockholder of Foglight in connection
with any breach by such stockholder of the Voting Agreement.

         8.2 Escrow Period. The "Escrow Period" shall commence on the Closing
Date and terminate at the expiration of nine (9) 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 Stockholders' 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 at or 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, and the nature of the Indemnifiable Item, 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.


                                       41


<PAGE>   46

             (b) For the purpose of compensating Quest for its Damages from the
Escrow Fund, 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 period of five trading days ending on the
trading day preceding the date on which Quest Common Stock is delivered by the
Escrow Agent to Quest. As an alternative, any Former Foglight Stockholder shall
have the right to satisfy such Stockholder's portion of any Damages with cash
instead of with shares of Quest Common Stock from the Escrow Fund.

         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 Stockholders' 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 Stockholders' Agent to make such
delivery. After the expiration of such 15-day period, the Escrow Agent shall
make delivery of 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 Stockholders' 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 Stockholders' 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 Stockholders' Agent. If after such 30-day period there remains a dispute as
to any claims, the Stockholders' 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 Stockholders' 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 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 Stockholders' 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 Stockholders'
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


                                       42


<PAGE>   47

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
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 Stockholders' 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 Stockholders' Agent.

             (a) Dan Callahan shall be constituted and appointed as agent
("Stockholders' Agent") for and on behalf of the Foglight stockholders to give
and receive notices and communications, to authorize delivery to Quest of 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 Stockholders' 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 Stockholders' Agent,
and the Stockholders' Agent shall receive no compensation for its services.
Notices or communications to or from the Stockholders' Agent shall constitute
notice to or from each of the Foglight stockholders.

             (b) The Stockholders' Agent shall not be liable for any act done or
omitted hereunder as Stockholders' 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 Foglight
stockholders shall severally indemnify the Stockholders' Agent and hold it
harmless against any loss, liability or expense incurred without


                                       43

<PAGE>   48

gross negligence or bad faith on the part of the Stockholders' Agent and arising
out of or in connection with the acceptance or administration of its duties
hereunder.

             (c) The Stockholders' Agent shall have reasonable access to
information about Foglight and the reasonable assistance of Foglight's officers
and employees for purposes of performing its duties and exercising its rights
hereunder; provided, that the Stockholders' Agent shall treat confidentially and
not disclose any nonpublic information from or about Foglight to anyone (except
on a need to know basis to individuals who agree to treat such information
confidentially).

         8.7 Actions of the Stockholders' Agent. A decision, act, consent or
instruction of the Stockholders' Agent shall constitute a decision of all
Foglight stockholders 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 Foglight stockholder, and the Escrow Agent and Quest
may rely upon any decision, act, consent or instruction of the Stockholders'
Agent as being the decision, act, consent or instruction of each and every such
Foglight stockholder. 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 Stockholders' 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 Stockholders' Agent of such claim, and the
Stockholders' Agent on behalf of the Foglight stockholders for whom shares of
Quest Common Stock otherwise issuable or payable to them are deposited in the
Escrow Fund shall be entitled, at such stockholders' expense, to participate in
any defense of such claim. Unless the Stockholder's Agent elects to assume such
defense (with counsel reasonably acceptable to Quest, and, provided, that the
Stockholder'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 Stockholders' Agent, which consent shall not be unreasonably withheld. In
the event that the Stockholders' Agent has consented to any such settlement, the
Stockholders' Agent and the Former Foglight Stockholders 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 $50,000, in the aggregate has or have
been delivered to the Escrow Agent and Stockholders' 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. In determining
the amount of Damages, any materiality statement contained in any
representation, warranty or consent of Foglight shall be disregarded.


                                       44


<PAGE>   49

             (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 and paid for by Foglight 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).

             (c) The parties hereto understand and agree that the indemnity
obligations of the Former Foglight Stockholders under this Article VIII shall
terminate nine months from the Closing Date, except 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 this Agreement. Nothing herein
shall limit Quest's or the Surviving Corporation's rights to seek recourse
against any person or entity for claims based on fraud.

         8.10 Exclusivity. The rights of Quest and the Surviving Corporation
under this Article VIII and the Escrow Agreement shall be the exclusive remedy
of such parties with respect to the Indemnifiable Items, except with respect to
claims based on fraud.

                                   ARTICLE IX
                               GENERAL PROVISIONS

         9.1 Survival of Representations, Warranties and Agreements. All
representations, warranties, covenants and agreements in this Agreement or in
any instrument delivered pursuant to this Agreement shall survive the
consummation of the Merger and shall terminate nine months after the Closing
Date.

                                 AMENDMENT NO.1
                                       TO
                          AGREEMENT AND PLAN OF MERGER

         This Amendment No. 1, dated as of December 7, 1999 (this "Amendment"),
to the Agreement and Plan of Merger, dated as of November 10, 1999 (the "Merger
Agreement"), by and among Quest Software, Inc. ("Quest"), a California
corporation, Quest Acquisition Corporation II, Inc., a Delaware corporation and
a wholly-owned subsidiary of Quest ("Sub"), and Foglight Software, Inc. a
Delaware corporation ("Foglight"), is entered into among Quest, Sub and
Foglight.

                                    RECITALS:

         WHEREAS, Quest, Sub and Foglight have previously entered into the
Merger Agreement, which contemplates the acquisition of all of the outstanding
equity interests in the Foglight by Quest by means of a merger of Sub with and
into Foglight (the "Merger"); and

         WHEREAS, the parties to the Merger Agreement desire to amend certain
terms of such agreement in the manner set forth below.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Quest, Sub and Foglight hereby agree as follows:

         1. The definition of "Excess Liabilities" in Section 2.1 of the Merger
Agreement is hereby deleted in its entirety from the Merger Agreement and
replaced with the following definition:

         "Excess Liabilities" means any and all liabilities for borrowed money
and capital lease obligations of Foglight in excess of $3.5 million existing as
of the Closing Date, including, without limitation, an amount equal to all
outstanding principal and accrued and unpaid interest under the Promissory Notes
as of the date immediately prior to the Closing Date, and the liabilities
referred to in the line items on the September 30, 1999 Balance Sheet as
"Leaseline-Short Term," "Notes Payable-Short Term," "Notes Payable-Long Term,"
and "Leaseline-Long Term," but excluding any Advances (as defined in Section
5.19) made by Quest to Foglight pursuant to Section 5.19 hereof."


<PAGE>   55

         2. The language in subsection (a) of Section 3.2 of the Merger
Agreement is hereby deleted in its entirety from the Merger Agreement and
replaced with the following language:

            "(a) The authorized capital stock of Foglight consists of 16,600,000
shares of Common Stock, $0.001 par value per share, of which 5,503,592 shares
are issued and outstanding; 710,029 shares of Series A Preferred Stock, $0.001
par value per share, of which 618,680 shares are issued and outstanding;
1,700,000 shares of Series B Preferred Stock, $0.001 par value per share, of
which 1,238,390 shares are issued and outstanding; and 4,789,250 shares of
Series C Preferred Stock, $0.001 par value per share, of which 2,500,000 shares
are issued and outstanding. All of the Foglight Capital Stock is owned,
beneficially and of record, only by the stockholders listed in Section 3.2(a) of
the Foglight Disclosure Schedule, which lists the names, addresses and number of
shares held by each stockholder. All of the outstanding Foglight Capital Stock
has been duly authorized, validly issued and is fully paid and nonassessable and
was 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 Foglight 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, granted or issued
by Foglight providing for the purchase, issuance, sale or pledge of any shares
of capital stock of Foglight or any securities convertible into or exchangeable
for any shares of Foglight Capital Stock (collectively, "Foglight Rights").
Section 3.2(a) of the Foglight Disclosure Schedule also contains a schedule
listing each holder of a Foglight Right granted or issued by Foglight, the
number of rights held by such holder and the number of shares reserved under all
stock incentive plans of Foglight. All Foglight Rights issued or granted by
Foglight were issued in compliance with all applicable federal and state
securities laws. Except as set forth in Section 3.2(a) of the Foglight
Disclosure Schedule, there are no obligations, contingent or otherwise, of
Foglight to repurchase, redeem or otherwise acquire any shares of Foglight
Capital Stock or make any investment (in the form of a loan, capital
contribution or otherwise) in any other entity. An updated Section 3.2(a) of the
Foglight Disclosure Schedule reflecting the changes permitted by this Agreement
between the date hereof and the Effective Time shall be delivered by Foglight to
Quest on the Closing Date."

         3. The language in subsection (m) of Section 5.1 of the Merger
Agreement is hereby deleted in its entirety from the Merger Agreement and
replaced with the following language:

            "(m) Incur any indebtedness for borrowed money or guarantee any such
indebtedness or issue or sell any debt securities or guarantee any debt
securities of others other than the indebtedness of the Promissory Notes or the
Advances (as defined in Section 5.19)."

         4. The following language shall be added to the Merger Agreement as
Section 5.19 thereof, immediately following the end of the last sentence of
Section 5.18 of the Merger Agreement:

            "5.19 Advances. Subject to the terms and conditions set forth
herein, Quest agrees to advance to Foglight from time to time pursuant to a
promissory note in the form attached as Exhibit 5.19, during the period from
December 14, 1999 and continuing until the earlier of the termination of this
Agreement pursuant to Section 7.1 hereof and the Effective Time (the


                                       2


<PAGE>   56

"Advance Period"), such amounts as Foglight may reasonably request hereunder to
fund the operations of Foglight during the Advance Period (subject to the
restrictions contained in Section 5.1) (each such loan an "Advance" and
collectively the "Advances"); provided, however, that the aggregate principal
amount of each Advance shall not be less than Two Hundred and Fifty Thousand
Dollars ($250,000) or more than Three Hundred Thousand Dollars ($300,000) and
provided, further that the obligation to make any Advance is subject to the
satisfaction of the following conditions, each in form and substance reasonably
satisfactory to Quest:

                (a) Foglight shall request each Advance by delivering to Quest a
written notice (the "Notice") at least five (5) business days prior to the date
specified in such Notice that Foglight desires the Advance to be disbursed,
which Notice shall specify that the Advance shall not, without the prior written
consent of Quest, be used for any action by Foglight that is not authorized
under the terms of Section 5.1 of this Agreement;

                (b) Foglight shall provide Quest with a reasonable opportunity
to review the proposed uses of the Advance with Foglight management prior to the
Advance Date (as defined below); and

                (c) Foglight shall not be in material breach of this Agreement
at the time such Notice is delivered or on the Advance Date (as defined below).

Subject to the foregoing conditions, disbursements of any Advance shall be made
by wire transfer to the account of Foglight before the close of business on the
applicable Advance Date (as defined herein), which in no event shall be later
than five (5) business days following Foglight's satisfaction of the above
conditions (with each date of actual disbursement of the Advance referred to
herein as an "Advance Date"); provided, however, that Quest shall not be deemed
to be in default hereunder if it fails to make such Advance provided that it
cures such failure within five (5) business days after written notice thereof by
Foglight."

         5. The language in subsection (a)(v) of Section 7.1 of the Merger
Agreement is hereby deleted in its entirety from the Merger Agreement and
replaced with the following language:

            "(v) by Quest, by giving written notice to Foglight, if the Closing
         shall not have occurred on or before January 31, 2000 by 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);"

         6. The language in subsection (a)(vi) of Section 7.1 of the Merger
Agreement is hereby deleted in its entirety from the Merger Agreement and
replaced with the following language:

            "(vi) by Foglight, by giving written notice to Quest, if the Closing
         shall not have occurred on or before January 31, 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


                                       3

         Foglight of any representation, warranty, or covenant of Foglight
         contained in this Agreement or Foglight's failure to fulfill a
         condition precedent to Closing or other default); or"

         7. All references in this Amendment to capitalized terms that are not
otherwise defined shall be given the meanings ascribed to them in the Merger
Agreement.

         8. Except as expressly stated in this Amendment, all of the remaining
terms of the Merger Agreement shall remain in full force and effect.

                                 PROMISSORY NOTE

                                                       Dated: December ___, 1999

         FOR VALUE RECEIVED, the undersigned, Foglight Software, Inc. a Delaware
corporation ("Obligor"), hereby promises to pay to the order of Quest Software,
Inc., a California corporation ("Holder"), the principal amount equal to all
sums advanced to Obligor hereunder, together with interest on the principal
amount outstanding from time to time, computed at a rate of seven percent (7%)
per annum. This Note is issued pursuant to Section 5.19 of that certain
Agreement and Plan of Merger dated as of November 10, 1999 by and among Obligor,
Holder and a wholly owned subsidiary of Holder, as amended by Amendment No. 1
thereto dated as of December __, 1999 (the "Merger Agreement"), and is subject
to the terms and conditions of such Merger Agreement.

         All amounts so advanced hereon and all payments made on account of the
principal hereof shall be recorded by Holder on Exhibit A hereto, which records
shall be conclusive and binding on the Obligor; but the Holder's failure to
record shall not release the Obligor from any of its obligations hereunder.

         All then outstanding principal and accrued interest thereon outstanding
under the terms hereof shall be due and payable in full thirty days following
termination of the Merger Agreement pursuant to Section 7.1 thereof. In
addition, all principal and accrued and unpaid interest thereon outstanding
under the terms hereof shall be due and payable on demand, at the option of
Holder, upon the failure to perform any covenant contained in the Security
Agreement (as defined below), which failure shall continue for more than ten
(10) days following notice thereof from Holder to Obligor.

         This Note shall be secured by all of the tangible and intangible
property of Obligor. In order to evidence that security interest, Obligor has
entered into that certain Security Agreement dated as of October 20, 1999 (the
"Security Agreement"). Obligor acknowledges and agrees that this Note is issued
subject to the Security Agreement and that the Holder is entitled to any and all
remedies set forth in the Security Agreement in the event that the Obligor
defaults on its obligations in this Note. Obligor also agrees to execute all
reasonable financing statements in favor of Holder in order to allow Holder to
perfect such security interest.

         Holder acknowledges that Comdisco Inc. and Phoenix Leasing currently
hold a security interest on such assets and that any claims by Holder shall be
secondary to any collection by these companies based upon any Promissory Notes
executed prior to the date that the first advance is made by Holder to Obligor
pursuant to Section 5.19 of the Merger Agreement and this Note.

<PAGE>   61

         Obligor promises to pay all costs of collection, including, but not
limited to, reasonable attorneys' fees, and all expenses incurred by Holder, on
