Borrower) is subtracted from (b) the lesser of (i) the Borrowing Base and (ii)

absence of the occurrence and continuation of an Event of Default, shall be

Section 2.08, equal to the least of:

                  (a) $50,000,000 minus the Liquidity Reserve and minus the
         Additional Liquidity Reserve,

                  (b) an amount equal to the result of (i) sum of (A) 65% of the
PV-10 Value of the Borrower's Proved Developed Producing Reserves, as reflected

Borrower's Proved Developed Non-producing Reserves, as reflected in the most

the benefit of the Lender Group, and (C) 40% of the PV-10 Value of the
Borrower's Proved Undeveloped Reserves, as reflected in the most recent report

         Anything to the contrary in this Agreement notwithstanding, the
Administrative Agent may, and shall at the request of the Required Lenders,
create reserves against the Borrowing Base or reduce the advance rates against
the stated categories of oil and gas reserves without declaring an Event of
Default as Administrative Agent determines, in its reasonable judgment (from the
perspective of an asset-based lender), as being appropriate to reflect
impediments to Collateral Agent's ability to realize upon the Collateral or
impairments or reductions to the value of the Collateral (in each case, an
"Agent Reserve", and collectively, the "Agent Reserves"). Without limiting the
generality of the foregoing, Agent Reserves may include (but are not limited to)
reserves based upon (i) past due or accrued taxes or other governmental changes,
including ad valorem, personal property and other taxes which may have priority
over the Liens or security interests of Collateral Agent in the Collateral; (ii)
Liens in favor of third Persons (whether or not such Liens are Excepted Liens);
(iii) estimates of present and future costs, expenses, deposits and liabilities
related to the plugging and abandonment of the Oil and Gas Properties (net of
the amount thereof which has been taken into account in the most recent Reserve
Report or is fully secured by an escrow arrangement acceptable to Agents), and
(iv) without duplication of the foregoing, amounts owing by such Borrower to any
Person to the extent secured by a Lien (whether or not such Lien is a Excepted
Lien) on, or trust (constructive or otherwise) over, any of the Collateral
(including proceeds thereof or collections from the sale of Hydrocarbons which
may from time to time come into the possession of any of the Lender Group or its
agents), which Lien or trust, in the reasonable determination of Administrative
Agent (from the perspective of an asset-based lender), has a reasonable
possibility of having a priority superior to the Collateral Agent's Liens (such
as landlord liens, ad valorem taxes, production taxes, severance taxes, sales
taxes, collections attributable to sale of Hydrocarbons of Persons other than
Borrower) in and to such item of Collateral, proceeds or collection.. Borrower
and Agent understand and agree that any amount of Agent Reserves shall not be
considered a disbursement bearing interest hereunder, but rather simply shall be
an amount that is not available for borrowing by Borrower.

         "Business Day" shall mean any day other than a day on which commercial
banks are authorized or required to close in New York, New York or Los Angeles,
California.

         "Change of Control" shall mean each occurrence of any of the following:

(within the meaning of Section 13(d)(3) of the Exchange Act), other than the

<PAGE>   14

         (b) during any period of two consecutive years, individuals, other than
directors elected by the Permitted Holders), who at the beginning of such period

whose election or appointment by such board or whose nomination for election by
the stockholders of QSRD was approved by a vote of a majority of the directors
then still in office who were either directors at the beginning of such period
or whose election or nomination for election was previously so approved) cease
for any reason to constitute a majority of the Board of Directors of QSRD then
in office other than directors elected by the Permitted Holders; or

         (c) less than 100% of all of the Stock of any Obligor (other than QSRD)
shall be owned and controlled, beneficially, directly, and of record, by QSRD or
the Borrower.

         "Closing Date" shall mean October 22, 1999.

         "Code" shall mean the Internal Revenue Code of 1986, as amended from
time to time and any successor statute.

liability company, solely in its capacity as collateral agent for the Lenders,

non-public information supplied to any member of the Lender Group by the
Obligors pursuant to this Agreement or the other Loan Documents which is
identified in writing by Borrower on behalf of the Obligors as being
confidential pursuant to this definition or otherwise at, or reasonably
concurrent with, the time the same is delivered to such member of the Lender
Group (and which at the time is not, and does not thereafter become, publicly
available or available to such member of the Lender Group from another source
not known by such member of the Lender Group to be subject to a confidentiality
obligation not to disclose such information). The foregoing provision relative
to timing of Borrower's identification of such information as being confidential
notwithstanding, the following categories of information that is confidential,
proprietary, or non-public hereby are designated by Borrower as confidential for
purposes of this definition (subject to the same not being publicly available or
available to such member of the Lender Group from another source not known by
such member of the Lender Group to be subject to a confidentiality obligation
not to disclose such information): all non-public geological, seismic,
geophysical, engineering, and reserve data related to the oil and gas

extension of a Letter of Credit, the Administrative Agent shall issue such
Letter of Credit to the beneficiary thereof.

         In conjunction with the issuance of each Letter of Credit, the Borrower
shall execute a Letter of Credit Agreement. In the event of any conflict between
any provision of a Letter of



                                      -28-
<PAGE>   37

Credit Agreement and this Agreement, QSRD, the Borrower, the Agents and the
Lenders hereby agree that the provisions of this Agreement shall govern.

         The Administrative Agent will send to the Borrower, the Collateral
Agent, and each Lender, immediately upon issuance of any Letter of Credit, or an
amendment thereto, a true and complete copy of such Letter of Credit, or such
amendment thereto.

         Section 2.03. Changes of Commitments.

                  (a) The Aggregate Commitments shall at all times be equal to
the lesser of (i) the Aggregate Maximum Credit Amounts, after adjustments
resulting from reductions pursuant to Sections 2.03(b), or (ii) the Borrowing
Base as determined from time to time.

                  (b) The Borrower shall have the right to terminate or to
reduce the amount of the Aggregate Maximum Credit Amounts at any time or from
time to time upon not less than three (3) Business Days prior notice to the
Administrative Agent (which shall promptly notify the Lenders) of each such
termination or reduction, which notice shall specify the effective date thereof
and the amount of any such reduction (which shall not be less than $5,000,000 or
any whole multiple of $1,000,000 in excess thereof) and shall be irrevocable and
effective only upon receipt by the Administrative Agent.

                  (c) The Aggregate Maximum Credit Amounts once terminated or
reduced may not be reinstated.

         Section 2.04. Fees.

                  (a) Financial Examination and Appraisal Fees. The Borrower
shall pay to the Administrative Agent, for the sole and separate account of
Administrative Agent: (i) Administrative Agent's customary fee of $750 per day
per examiner, plus Administrative Agent's reasonable out-of-pocket expenses for
each financial analysis and examination (i.e., audits) of the Obligors performed
by personnel employed by Administrative Agent; and (ii) Administrative Agent's
out-of-pocket expenses for each appraisal of the Collateral performed by
personnel employed by Administrative Agent; and (iii) the actual charges paid or
incurred by Administrative Agent if it elects to employ the services of one or
more third Persons to perform such financial analyses and examinations (i.e.,
audits) of the Obligors or to appraise the Collateral.

                  (b) Fee Letter Fees. Borrower shall pay to the Collateral
Agent the fees set forth in the Fee Letter in accordance with the terms thereof,
and such fees constitute Indebtedness hereunder.

                  (c) Letter of Credit Fee. Borrower shall pay Administrative
Agent, for the sole and separate account of the Collateral Agent, a fee (in
addition to the charges, commissions, fees, and costs set forth in Section
2.16(d)) equal to 3.0% per annum times the amount of the undrawn Letters of
Credit. Notwithstanding the foregoing, at any time that an Event of Default has
occurred and is continuing and Borrower has not provided cash collateral to the
Administrative Agent pursuant to Section 2.16(e), the Letter of Credit fee
payable by the



                                      -29-
<PAGE>   38

Borrower pursuant to this Section 2.04(c) shall equal to 6.0% per annum times
the amount of the undrawn Letters of Credit. Such fees shall be due and payable
monthly, in arrears, on the first day of each month during the term hereof.

         Section 2.05. Several Obligations. The failure of any Lender to make
any Loan to be made by it or to provide disbursements or reimbursements under
Letters of Credit on the date specified therefor shall not relieve any other
Lender of its obligation to make its Loan or provide funds on such date, but no
Lender shall be responsible for the failure of any other Lender to make a Loan
to be made by such other Lender or to provide funds to be provided by such other
Lender.

         Section 2.06. Loan Account. The Administrative Agent shall maintain an
account on its books in the name of the Borrower (the "Loan Account") on which
the Borrower will be charged with all Loans made by Administrative Agent or the
Lenders to the Borrower or for the Borrower's account, including, accrued
interest, Lender Group Expenses, and any other Indebtedness. Administrative
Agent shall render monthly statements regarding the Loan Account to the Borrower
(with copies to the Lenders), including principal, interest, fees, and including
an itemization of all charges and expenses constituting Lender Group Expenses
owing, and such statements shall be conclusively presumed to be correct and
accurate and constitute an account stated between the Borrower and the Lender
Group unless, within 30 days after receipt thereof by the Borrower and the
Lenders, the Borrower or any Lender shall deliver to Administrative Agent
written objection thereto describing the error or errors contained in any such
statements. The Borrower hereby authorizes Administrative Agent to, and
Administrative Agent may, from time to time charge the Loan Account with all
Indebtedness (including all Loans as and when advanced and all interest accrued
thereon as and when due and payable hereunder and all Lender Group Expenses as
and when incurred) and any other amount due and payable under any Loan Document
to which the Borrower is a party, whether or not any Event of Default or Default
shall have occurred or be continuing or whether any of the conditions precedent
in Section 6.02 have been satisfied. Any amount charged to the Loan Account
shall be deemed a Loan hereunder made by the Lenders to the Borrower. The
Borrower confirms that any charges which Administrative Agent may so make to the
Loan Account as herein provided will be made as an accommodation to the Borrower
and solely at Administrative Agent's discretion. Whenever any payment to be made
under any such Loan Document shall be stated to be due on a day other than a
Business Day, such payment shall be made on the next succeeding Business Day and
such extension of time shall in such case be included in the computation of
interest or fees, as the case may be, provided that, if any such payment is made
by a charge to the Loan Account, such charge may be made by Administrative Agent
for the benefit of the Lender Group on any day, whether or not a Business Day.

         Section 2.07. Prepayments.

                  (a) Generally. The Borrower may prepay Base Rate Loans upon
written or telephonic notice to the Administrative Agent (which shall promptly
notify the Lenders) on or prior to 11:00 a.m. (Los Angeles time) on the date of
prepayment, which notice, if



                                      -30-
<PAGE>   39

telephonic, shall be immediately confirmed in writing. The notice shall specify
the prepayment date (which shall be a Business Day) and the amount of the
prepayment and shall be irrevocable and effective only upon receipt by the
Administrative Agent, provided that interest on the principal prepaid, accrued
to the prepayment date, shall be paid on the prepayment date. Prepayments shall
be by wire transfer of immediately available federal funds and if received by
the Administrative Agent on a non-Business Day or after 11:00 a.m. (Los Angeles
time) on a Business Day shall be deemed to have been received by the
Administrative Agent as of the opening of business on the immediately following
Business Day.

                  (b) Following Reduction of Credit Amounts. If, after giving
effect to any termination or reduction of the Aggregate Maximum Credit Amounts
pursuant to Section 2.03(b), the outstanding aggregate principal amount of the
Loans plus the Letter of Credit Usage exceeds the Aggregate Maximum Credit
Amounts, the Borrower shall prepay the Loans on the date of such termination or
reduction in an aggregate principal amount equal to the excess, together with
interest on the principal amount paid accrued to the date of such prepayment.

                  (c) Following Re-determination. Upon any re-determination or
adjustment of the amount of the Borrowing Base in accordance with Section 2.08
or adjustment in accordance with Sections 8.08(b) or 9.14, if the re-determined
or adjusted Borrowing Base is less than the sum of the aggregate outstanding
principal amount of the Loans plus the Letter of Credit Usage, then the Borrower
shall, within 3 Business Days of such determination or adjustment, prepay the
Loans in an aggregate principal amount equal to such excess, together with
interest on the principal amount paid accrued to the date of such prepayment.

                  (d) No Premium; Penalty. Prepayments permitted or required
under this Section 2.07 shall be without premium or penalty. Any prepayment may
be reborrowed during the Revolving Credit Period subject to the then effective
Aggregate Commitments.

         Section 2.08. Borrowing Base.

                  (a) The Borrowing Base shall be determined (as to reserve
quantities and price) in accordance with Section 2.08(b) by the Administrative
Agent with the concurrence of the Required Lenders and is subject to
re-determination in accordance with Section 2.08(d). Upon any re-determination
of the Borrowing Base, such re-determination shall remain in effect until the
next successive Re-determination Date. "Re-determination Date" shall mean the
date that the re-determined Borrowing Base becomes effective subject to the
notice requirements specified in Section 2.08(e) both for scheduled
re-determinations and unscheduled re-determinations. So long as any of the
Commitments are in effect or any Loans are outstanding hereunder, this Agreement
shall be governed by the then effective Borrowing Base. During the period from
and after the Closing Date until the first Re-determination Date to occur after
the Closing Date, unless re-determined pursuant to Section 2.08(d) or adjusted
pursuant to Sections 2.08(c), 8.08(b) or 9.14, the amount of the



                                      -31-
<PAGE>   40

Borrowing Base shall be $25,000,000, subject to monthly price adjustment as
provided in Section 2.08(f).

                  (b) Upon receipt of the reports required by Section 8.07(a)
through (d) and such other reports, data and supplemental information as may
from time to time be reasonably requested by the Agents (the "Engineering
Reports"), the Administrative Agent will calculate a re-determination of the
Borrowing Base. Such calculation will be in accordance with the provisions
contained in the definition of the term "Borrowing Base" in Section 1.02;
provided, however, the effect of any Risk Management Agreements or fixed price
sales contracts with investment grade counterparties, or purchasers shall be
taken into consideration by the Administrative Agent in making such calculation
and the resulting Borrowing Base shall be increased or decreased as the
Administrative Agent shall reasonably determined based upon such consideration.
The Administrative Agent shall notify the Lenders of the new Borrowing Base by
no later than the earlier of (i) 30 days following receipt by the Administrative
Agent of the Engineering Reports or (ii) 10 days prior to the next Scheduled
Re-determination Date, in each case assuming its receipt of the Engineering
Reports in a timely and complete manner.

                  (c) The Administrative Agent may exclude any Oil and Gas
Property or portion of production therefrom or any income from any other
Property from the Borrowing Base, at any time, because title information is not
reasonably satisfactory or such Property is not Mortgaged Property. Without
limitation of the forgoing, if the Escrow Agreement is terminated and the
Property subject thereof is not vested with the Borrower, then the Borrowing
Base shall be reduced by an amount equal to the value assigned such Property in
the most recently determined Borrowing Base.

                  (d) So long as any of the Commitments are in effect and until
payment in full of all Loans hereunder, on or around the 15th day of each March
and September, commencing March 15, 2000 (each being a "Scheduled
Re-determination Date"), the amount of the Borrowing Base shall be determined in
accordance with Section 2.08(b). Without limitation of the foregoing, the
Majority Lenders may initiate two (2) unscheduled re-determinations of the
Borrowing Base during any consecutive twelve (12) month period by specifying in
writing to the Borrower, with a copy to the Administrative Agent, the date on
which the Borrower is to furnish a Reserve Report in accordance with Section
8.07(b) and the date on which such re-determination is to occur. The Borrower
may also request two (2) unscheduled re-determinations during any consecutive
twelve (12) month period.

                  (e) The Administrative Agent shall promptly notify in writing
QSRD, the Borrower and the Lenders of the new Borrowing Base. Any
re-determination of the Borrowing Base shall not be in effect until written
notice is received by the Borrower.

                  (f) In addition to the re-determination of the Borrowing Base
as provided above, the valuation of the oil and gas reserves set forth in the
most recent Reserve Report shall be adjusted monthly by the Administrative Agent
with the concurrence of the Required Lenders, based upon the monthly pricing
report provided by the Borrower to the Administrative Agent pursuant to Section
8.07(e), such revaluation to be made by the



                                      -32-
<PAGE>   41

Administrative Agent within 5 Business Days of its receipt of each such report,
and the Administrative Agent shall promptly notify in writing QSRD, the Borrower
and the Lenders of the revalued Borrowing Base. Any revaluation of the Borrowing
Base shall not be in effect until written notice is received by the Borrower.

         Section 2.09. Registered Notes. The Borrower agrees to record each Loan
on the Register referred to in Section 12.06. Each Loan recorded on the Register
(the "Registered Loan") may not be evidenced by promissory notes other than
Registered Notes. Upon the registration of any Loan, the Borrower agrees, at the
request of any Lender, to execute and deliver to such Lender a promissory note,
in conformity with the terms of this Agreement, in registered form to evidence
such Registered Loan, in form and substance reasonably satisfactory to such
Lender, and registered as provided in Section 12.06(a) (a "Registered Note"),
payable to the order of such Lender and otherwise duly completed. Once recorded
on the Register, the Loan or Loans evidenced by such Registered Note may not be
removed from the Register so long as it remains outstanding, and a Registered
Note may not be exchanged for a promissory note that is not a Registered Note.

         Section 2.10. Securitization.

         The Borrower hereby acknowledges that the Lenders and any of their
Affiliates may sell or securitize the Loans (a "Securitization") through the
pledge of the Loans as collateral security for loans to such Lenders or their
Affiliates or through the sale of the Loans or the issuance of direct or
indirect interests in the Loans, which loans to such Lenders or their Affiliates
or direct or indirect interests will be rated by Moody's, Standard & Poor's or
one or more other rating agencies (the "Rating Agencies"). The Borrower (and
QSRD, if applicable) shall cooperate reasonably with such Lenders and their
Affiliates to effect the Securitization including, without limitation, by (a)
amending this Agreement and the other Loan Documents, and executing such
additional documents, as reasonably requested by such Lenders, in connection
with the Securitization; provided that (i) any such amendment or additional
documentation does not impose material additional costs on the Obligors, and
(ii) any such amendment or additional documentation does not materially
adversely affect the rights, or materially increase the obligations (including
administrative duties or reporting obligations), of the Obligors under the Loan
Documents or change or affect in a manner adverse to the Borrower the financial
terms of the Loans, (b) providing such information as may be reasonably
requested by such Lenders in connection with the rating of the Loans or the
Securitization, (c) providing in connection with any rating of the Loans, a
certificate (i) agreeing to indemnify such Lenders and any of their Affiliates,
any of the Rating Agencies, or any party providing credit support or otherwise
participating in the Securitization (collectively, the "Securitization Parties")
for any losses, claims, damages or liabilities (the "Liabilities") to which such
Lenders, their Affiliates or such Securitization Parties may become subject
insofar as the Liabilities arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in any Loan Document
or in any writing delivered by or on behalf of the Obligors and their respective
Affiliates to the Lender Group in connection with any Loan Document or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary



                                      -33-
<PAGE>   42

in order to make the statements therein, in light of the circumstances under
which they were made, not misleading and such indemnity shall survive any
transfer by such Lenders or their successors or assigns of the Loans and (ii)
agreeing to reimburse such Lenders and any of their Affiliates and other
Securitization Parties for any legal or other expenses reasonably incurred by
such Persons in connection with defending the Liabilities; and (d) providing
such information regarding the Obligors, the Collateral and other property,
assets and business of the Obligors (including appraisals and valuations) as may
be reasonably requested by such Lenders or their successors or assignees.

         Section 2.11. Administrative Procedures and Settlement.

                  (a) Anything contained herein to the contrary notwithstanding,
the becoming due of any amount required to be paid under this Agreement, the Fee
Letter, any Registered Note, or any other Loan Document, whether of principal or
interest or fees or expenses or for any other Indebtedness, shall be deemed
irrevocably to be a request by the Borrower for a Loan on the due date in the
amount required to pay such principal, interest, fee, expense, or other
Indebtedness.

                  (b) Administrative Agent shall from time to time, but no less
frequently than weekly, notify each Lender of the date such Lender is to fund
its Loans, and the amount to be made available by it. If and to the extent that
a Lender and Administrative Agent so agree, at Administrative Agent's
discretion, the amount to be made available by such Lender on any date may be
netted against any amount owing to such Lender and otherwise payable by
Administrative Agent on account of payments received by it from the Borrower on
such date. The amount to be made available by each Lender on any date (which
date shall be a Business Day) shall be made available by it on such date to
Administrative Agent at the Administrative Agent Account, in immediately
available funds, not later than 12:00 p.m. (Los Angeles time). The obligation of
each Lender to Administrative Agent (as opposed to the Borrower) to fund its
Loans on the date specified by Administrative Agent is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including (i) any set off, counterclaim, recoupment, defense or other right
which such Lender may have against Administrative Agent, the Borrower or any
other Person for any reason whatsoever, (ii) the financial condition or
prospects of the Borrower, (iii) the failure of any other such Lender to make
funds available to Administrative Agent with respect to its Loans, (iv) the
occurrence or continuation of an Event of Default, whether the same shall occur
before or after Administrative Agent shall have made the Loans, or (v) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing.

                  (c) The Borrower and the Lender Group hereby irrevocably
authorize Administrative Agent to disburse the proceeds of each Loan requested,
or deemed to be requested, pursuant to this Agreement as follows: (i) the
proceeds of each Loan requested shall (if Administrative Agent so requires,
subject to receipt by Administrative Agent of funds from the Lenders) be
disbursed by Administrative Agent in lawful money of the United States of
America in immediately available funds, in the case of the initial borrowing, in
accordance with the terms of a written disbursement letter from the Borrower,
and in the



                                      -34-
<PAGE>   43

case of each subsequent borrowing, by wire transfer to the Designated Account or
such other bank account as may be agreed upon in writing by Borrower and
Administrative Agent from time to time, and (ii) the proceeds of each Loan
deemed made pursuant to Section 2.06 hereof shall be charged to the Loan Account
and disbursed by Administrative Agent by way of direct payment of the relevant
interest or other Indebtedness. The Borrower agrees to establish and maintain
the Designated Account with the Designated Account Bank for the purpose of
receiving the proceeds of the Loans requested by Borrower and made by
Administrative Agent or the Lenders hereunder.

                  (d) The Borrower and the Lender Group hereby irrevocably
authorizes and directs Administrative Agent to charge to the Borrower's Loan
Account hereunder, as a Loan deemed made to the Borrower, a sum sufficient to
pay all interest accrued on the Indebtedness during the immediately preceding
month and to pay all Lender Group Expenses at any time owed by any Obligor to
the Lender Group hereunder or under any of the Loan Documents; provided,
however, that Administrative Agent may, but shall not be required to, so charge
the Borrower's Loan Account during the existence of an Event of Default or if a
Default would result therefrom. Amounts so charged pursuant to this Section
shall be deemed Loans requested by the Borrower pursuant hereto.

                  (e) (i) Loans and payments will be settled among
Administrative Agent and the Lenders according to such procedures as
Administrative Agent and such Lenders may agree from time to time. These
procedures notwithstanding, each such Lender's obligation to fund its portion of
the Loans shall commence on the date such Loans are made by Administrative
Agent; however, if the Administrative Agent makes a Loan in compliance with
Section 2.02(c)(ii), such Lender's obligation to remit its portion of the Loans
shall occur on that date on which its obligation to remit its portion of the
Loans otherwise would have occurred had the prior notice and frequency
requirements of Section 2.02(c)(i) been satisfied. The foregoing shall not
relieve any Lender of its obligations to fund hereunder, but merely affects the
time within which it is to perform such obligations. Such payments to
Administrative Agent will be made by such Lenders without set-off, counterclaim
or reduction of any kind.

                      (ii) Subject to subsection (e)(i) above, Administrative
Agent may require the Lenders to settle Loans and payments on a daily basis (or
such lesser frequency as Administrative Agent may determine) (each day of
settlement being a "Settlement Date"). Administrative Agent will advise each
Lender by telephone or telecopy of the amount of each such Lender's Percentage
Share (in accordance with its Commitment) of the Revolving Facility Usage as of
the close of business of the Business Day immediately preceding the Settlement
Date. In the event that payments are necessary to adjust such Lender's actual
Percentage Share (in accordance with its Commitment) of the Revolving Facility
Usage as of any Settlement Date to equal the amount of such Lender's required
Percentage Share (in accordance with its Commitment) of the Revolving Facility
Usage, the party from which such payment is due will pay the other, in same day
funds, by wire transfer to the other's account not later than the applicable
time set forth in subsection (b) above.



                                      -35-
<PAGE>   44

                           (iii) If any such payment is not made to
Administrative Agent by any such Lender on the Settlement Date applicable
thereto to the extent required by the terms hereof, such Lender shall be a
Defaulting Lender and Administrative Agent shall be entitled to recover for its
account such amount on demand from such Lender together with interest thereon at
the Defaulting Lenders Rate. Administrative Agent shall not be obligated to
transfer to a Defaulting Lender any payments made by Borrower to Administrative
Agent for the Defaulting Lender's benefit on account of its Loans. Any such
amounts payable to a Defaulting Lender shall instead be paid to or retained by
Administrative Agent. Administrative Agent may hold and, in its discretion,
re-lend to Borrower as Loans the amount of any or all such payments received or
retained by it for the account of such Defaulting Lender. Solely for the
purposes of voting or consenting to matters with respect to the Loan Documents
and determining Required Lenders, Defaulting Lender shall be deemed not to be a
"Lender" (in respect of its Loans and Commitment). This section shall remain
effective with respect to such Lender until (x) the Indebtedness under this
Agreement shall have been declared or shall have become immediately due and
payable or (y) the Lenders that are non-Defaulting Lenders and Administrative
Agent shall have waived such Lender's default in writing. The operation of this
section shall not be construed to increase or otherwise affect the Commitments
of any Lender other than such Defaulting Lender, or relieve or excuse the
performance by the Borrower of its duties and obligations hereunder.

         Section 2.12. Administrative Agent Advances.

                  (a) Subject to the limitations set forth in the proviso
contained in this Section 2.12, Administrative Agent hereby is authorized by the
Borrower and the Lenders, from time to time in Administrative Agent's sole
discretion, (i) after the occurrence and during the continuance of a Default, or
(ii) at any time that any of the other applicable conditions precedent set forth
in Section 6.02 have not been satisfied, to make Loans to the Borrower on behalf
of the Lenders that Administrative Agent, in its discretion, deems necessary or
desirable (A) to preserve or protect the Collateral, or any portion thereof, (B)
to enhance the likelihood of repayment of the Indebtedness, or (C) to pay any
other amount chargeable to the Borrower pursuant to the terms of this Agreement,
including Lender Group Expenses and the costs, fees, and expenses described
herein (any of the Loans described in this Section 2.12 being hereinafter
referred to as "Administrative Agent Advances"); provided, however, that at no
time shall the aggregate amount of outstanding Administrative Agent Advances
under this Section 2.12(a) exceed the result of (1) the lesser of (A)
$2,500,000, and (B) 7.5% of the Borrowing Base then in effect, minus (2) the
amount of optional Overadvance Loans made by the Administrative Agent to the
Borrower pursuant to Section 2.13(a).

                  (b) Administrative Agent Advances shall be repayable on
demand, shall be secured by the Collateral Agent's Liens on the Collateral,
shall constitute Loans and Indebtedness hereunder, shall be allocated between
the Lenders (based upon their respective Percentage Shares), and shall bear
interest at the rate applicable from time to time to the Loans pursuant to
Section 3.02 hereof.

         Section 2.13. Optional Overadvances.



                                      -36-
<PAGE>   45

                  (a) Any contrary provision of this Agreement notwithstanding,
if the condition precedent set forth in Section 6.02(d) will not be satisfied in
respect to a particular Borrowing, the Lenders nonetheless hereby authorize
Administrative Agent and Administrative Agent may, but is not obligated to,
knowingly and intentionally continue to make Loans (on behalf of the Lenders) to
the Borrower such failure of condition notwithstanding, so long as, at any time,
(i) the outstanding Revolving Facility Usage does not exceed the Borrowing Base
by the result of (A) the lesser of (1) $2,500,000, and (2) 7.5% of the Borrowing
Base then in effect, minus (B) the amount of Administrative Agent Advances made
by the Administrative Agent to the Borrower pursuant to Section 2.12(a), and
(ii) the outstanding Revolving Facility Usage (except for and excluding amounts
charged to the Loan Account for interest, fees, or Lender Group Expenses) does
not exceed $50,000,000. The foregoing provisions are for the sole and exclusive
benefit of the Agents and the Lenders and are not intended to benefit the
Obligors in any way. The Loans that are made pursuant to this Section shall be
subject to the same terms and conditions as any other Loan, except that the rate
of interest applicable thereto shall be the Post-Default Rate without regard to
the presence or absence of a Default or Event of Default and the Administrative
Agent may make any such Loan without regard to the 5 Business Day notice
requirement set forth in Section 2.02(c).

                  (b) In the event Administrative Agent obtains actual knowledge
that the Revolving Facility Usage exceeds the amounts permitted by the preceding
paragraph, regardless of the amount of or reason for such excess, Administrative
Agent shall notify Lenders as soon as practicable (and prior to making any (or
any further) intentional Overadvances (except for and excluding amounts charged
to the Loan Account for interest, fees, or Lender Group Expenses) unless
Administrative Agent determines that prior notice would result in imminent harm
to the Collateral, or its value, and the Lenders thereupon shall, together with
Administrative Agent, jointly determine the terms of arrangements that shall be
implemented with the Borrower intended to reduce, within a reasonable time, the
outstanding principal amount of the Loans to an amount permitted by the
preceding paragraph. In the event any Lender disagrees over the terms of
reduction or repayment of any Overadvance, the terms of reduction or repayment
thereof shall be implemented according to the determination of the Majority
Lenders.

                       Each Lender shall be obligated to settle with
Administrative Agent as provided in Section 2.12 for the amount of such Lender's
Percentage Share of any unintentional Overadvances by Administrative Agent
reported to such Lender, any intentional Overadvances made as permitted under
this Section, and any Overadvances resulting from the charging to the Loan
Account of interest, fees, or Lender Group Expenses.

         Section 2.14. Apportionment, Application, and Reversal of Payments. (i)
Except as otherwise provided with respect to Defaulting Lenders, and subject to
the Administrative Agent reservation of the right, in its sole discretion, to
exclude from any such payment collections that the Administrative Agent
determines may constitute amounts attributable to trust fund taxes or
Hydrocarbon Interests of third persons and subject to any other agreement among
the Lenders regarding the application of payments, aggregate principal and
interest payments shall be apportioned ratably among the Lenders (according to
the unpaid principal balance of the Indebtedness to which such payments relate
held by each individual Lender, but subject to the Fee Split Letter) and
payments of fees and expenses (other than fees



                                      -37-
<PAGE>   46

designated for Administrative Agent's or Collateral Agent's sole and separate
accounts) shall, as applicable, be apportioned ratably among the Lenders (in
accordance with their applicable Percentage Share, but subject to the Fee Split
Letter). All payments on account of the payment of the Indebtedness shall be
remitted to Administrative Agent and all such payments and all proceeds of
Collateral received by any Agent, shall be applied as follows:

                  first, to pay any fees or Lender Group Expenses then due to
                  the Agents under the Loan Documents until paid in full,

                  second, to pay any fees or Lender Group Expenses then due
                  under the Loan Documents to the Lenders, in respect of their
                  Percentage Share thereof,

                  third, ratably to pay interest due in respect of all Loans
                  until paid in full;

                  fourth, ratably to pay principal of all Loans until paid in
                  full;

                  fifth, to be held by Administrative Agent as cash collateral
                  in accordance with Section 2.16(e) hereof with respect to
                  unreimbursed obligations in respect of Letters of Credit;

                  sixth, if an Event of Default has occurred and is continuing,
                  to pay any other Indebtedness due to the Agents or any Lender,
                  on a ratable basis, and

                  seventh, to Borrower and wired to its Designated Account.

         Administrative Agent shall promptly distribute to each Lender, pursuant
to the applicable wire transfer instructions received from each Lender in
writing, such funds as it may be entitled to receive as provided above, subject
to a settlement delay as provided in Section 2.11.

                                            (ii) For purposes of the foregoing,
"paid in full" with respect to interest shall include interest accrued after the
commencement of any Insolvency Proceeding irrespective of whether a claim for
such interest is allowable in such Insolvency Proceeding.

                                            (iii) In the event of a direct
conflict between the priority provisions of this Section 2.14 and other
provisions contained in any other Loan Document, it is the intention of the
parties hereto that both such priority provisions in such documents shall be
read together and construed, to the fullest extent possible, to be in concert
with each other. In the event of any actual, irreconcilable conflict that cannot
be resolved as aforesaid, the terms and provisions of this Section 2.14 shall
control and govern.

         Section 2.15. Cash Management.

                  (a) The Borrower shall (i) establish and maintain lock boxes
("Lockboxes") at one or more banks set forth on Schedule 2.15, and shall request
in writing and otherwise take



                                      -38-
<PAGE>   47

such reasonable steps to ensure that all Account Debtors forward payment
directly to such Lockboxes, and (ii) deposit and cause QSRD and the Subsidiary
Guarantors to deposit or cause to be deposited promptly, and in any event no
later than the first Business Day after the date of receipt thereof, all cash,
checks, drafts or other similar items of payment made in respect of any and all
Collateral (whether or not otherwise delivered to a Lockbox) into bank accounts
in such Obligor's name (each a "Collection Account" and, collectively, the
"Collection Accounts") at banks set forth on Schedule 2.15 (each a "Collection
Account Bank" and, collectively, the "Collection Account Banks"). Each Obligor
shall establish and maintain a concentration account in its name (each a
"Concentration Account" and, collectively, the "Concentration Accounts") at the
bank or banks which shall be designated as the concentration account bank for
each such Obligor on Schedule 2.15 (each a "Concentration Account Bank" and,
collectively, the "Concentration Account Banks"), which banks shall be
satisfactory to the Administrative Agent.

                  (b) Each Concentration Account Bank, the Designated Account
Bank, and all Collection Account Banks shall establish and maintain tri-party
blocked account agreements with the Administrative Agent and the applicable
Obligor, in form and substance acceptable to the Administrative Agent. Each such
blocked account agreement shall provide, among other things, that (i) all items
of payment deposited in such accounts and proceeds thereof deposited in the
applicable Concentration Account are held by such banks as agent or
bailee-in-possession for the Administrative Agent, (ii) the bank executing such
agreement has no rights of setoff or recoupment or any other claim against such
account, as the case may be, other than for payment of its service fee and other
charges directly related to the administration of such account and for returned
checks or other items of payment, and (iii)(A) with respect to each bank at
which a Collection Account is located, such bank agrees, from and after a
receipt of a notice (an "Activation Notice") from the Administrative Agent
(which Activation Notice may be given by Administrative Agent at any time at
which a Triggering Event shall have occurred and is continuing), to forward
immediately all amounts in each Collection Account to such Obligor's
Concentration Account Bank and to commence the process of daily sweeps from such
Collection Account into the applicable Concentration Account, and (B) with
respect to each Concentration Account Bank, such bank agrees from and after the
receipt of an Activation Notice from Administrative Agent upon the occurrence
and during the continuance of a Triggering Event, to immediately forward all
amounts received in the applicable Concentration Account to the Administrative
Agent's Account; provided, however, that Administrative Agent reserves the
right, in its sole discretion, to require that collections representing amounts
attributable to trust fund taxes or Hydrocarbon Interests of third Persons be
segregated by the Collection Account Banks and held in a separate account, (it
being the intent of the Administrative Agent, to the extent it has sufficient
information to do so, to so segregate trust fund taxes or Hydrocarbon Interests
of third Persons, and avoid the deposit of such funds into the Administrative
Agent's Account). From and after the date Administrative Agent has delivered an
Activation Notice to any bank with respect to any Collection's Account(s), no
Obligor shall, or shall cause or permit any Subsidiary thereof to, accumulate or
maintain cash in disbursement or payroll accounts as of any date of
determination in excess of checks outstanding against such accounts as of that
date and amounts necessary to meet minimum balance requirements.

                  (c) So long as no Default or Event of Default has occurred and
is continuing, the Obligors may amend Schedule 2.15 to add or replace a
Collection Account Bank, Lockbox or Collection Account or to replace any
Concentration Account or the Designated Account;



                                      -39-
<PAGE>   48

provided, however, that (i) Administrative Agent shall have consented in writing
in advance to the opening of such account or Lockbox with the relevant bank and
(ii) prior to the time of the opening of such account or Lockbox, the applicable
Obligor or the Subsidiaries thereof, as applicable, and such bank shall have
executed and delivered to Administrative Agent a tri-party blocked account
agreement, in form and substance satisfactory to Administrative Agent. The
Obligors shall close any of their accounts (and establish replacement accounts
in accordance with the foregoing sentence) promptly and in any event within 30
days of notice from Agent that the creditworthiness of any bank holding an
account is no longer acceptable in Administrative Agent's reasonable judgment,
or as promptly as practicable and in any event within 60 days of notice from
Administrative Agent that the operating performance, funds transfer or
availability procedures or performance with respect to accounts or lockboxes of
the bank holding such accounts or Administrative Agent's liability under any
tri-party blocked account agreement with such bank is no longer acceptable in
Administrative Agent's reasonable judgment.

                  (d) The Lockboxes, Collection Accounts, Designated Account and
the Concentration Accounts shall be cash collateral accounts, with all cash,
checks and similar items of payment in such accounts securing payment of the
Loans and all other Indebtedness, and in which each Obligor and each Subsidiary
Guarantor shall have granted a Lien to Administrative Agent pursuant to the
Security Agreement.

                  (e) Each Obligor shall and shall cause its Affiliates,
officers, employees, agents, directors or other Persons acting for or in concert
with such Obligor (each a "Related Person") to (i) hold in trust for
Administrative Agent all checks, cash and other items of payment received by
Obligor or any such Related Person, and (ii) within one (1) Business day after
receipt by such Obligor or any Related Person of any checks, cash or other items
of payment, deposit the same into an Obligor Account of such Obligor. Each
Obligor and each Related Person thereof acknowledges and agrees that all cash,
checks or items of payment constituting proceeds of Collateral are the property
of Collateral Agent for the benefit of the Lenders. All proceeds of the sale or
other disposition of any Collateral, shall be deposited directly into the
applicable Obligor Account.

         Section 2.16. Letter of Credit Subfacility.

                  (a) Subject to the terms and conditions of this Agreement,
Administrative Agent agrees to issue letters of credit for the account of
Borrower (each, an "L/C") or to issue guarantees of payment, indemnities,
participations and/or undertakings (each such guaranty, indemnity, participation
or undertaking an "L/C Guaranty") with respect to letters of credit issued by an
issuing bank for the account of Borrower. Agent shall have no obligation to
issue a Letter of Credit if any of the following would result:

                      (i) the aggregate amount of all Letter of Credit Usage
         would exceed the Borrowing Base minus the amount of all outstanding
         Loans; or

                      (ii) the aggregate amount of all Letter of Credit Usage
         would exceed the Maximum Credit Amount minus the amount of all
         outstanding Loans; or



                                      -40-
<PAGE>   49

                      (iii) the outstanding Indebtedness would exceed the
         Maximum Credit Amount; or

                      (iv) the aggregate amount of all Letters of Credit Usage
         would exceed the L/C Commitment.


Borrower expressly understands and agrees that Administrative Agent shall have
no obligation to arrange for the issuance by issuing banks of the letters of
credit that are to be the subject of L/C Guarantees. Borrower and the Lender
Group acknowledge and agree that certain of the letters of credit that are to be
the subject of L/C Guarantees may be outstanding on the Closing Date. Each
Letter of Credit shall have an expiry date no later than as provided in Section
6.03 and all such Letters of Credit shall be in form and substance acceptable to
Administrative Agent in its sole discretion. If the Lender Group is obligated to
advance funds under a Letter of Credit, Borrower immediately shall reimburse
such amount to Administrative Agent and, in the absence of such reimbursement,
the amount so advanced immediately and automatically shall be deemed to be a
Loan hereunder and, thereafter, shall bear interest at the rate then applicable
to such Advances under Section 3.02.

                  (b) Borrower hereby agrees to indemnify, save, defend, and
hold the Lender Group harmless from any loss, cost, expense, or liability,
including payments made by the Lender Group, expenses, and reasonable attorneys
fees incurred by the Lender Group arising out of or in connection with any
Letter of Credit, other than those resulting from the gross negligence or
willful misconduct of any member of the Lender Group. Borrower agrees to be
bound by the issuing bank's regulations and interpretations of any Letters of
Credit guaranteed by the Lender Group and opened to or for Borrower's account or
by Administrative Agent's interpretations of any L/C issued by the Lender Group
to or for Borrower's account, even though this interpretation may be different
from Borrower's own, and Borrower understands and agrees that the Lender Group
shall not be liable for any error, negligence, or mistake, whether of omission
or commission, in following Borrower's instructions or those contained in the
Letter of Credit or any modifications, amendments, or supplements thereto.
Borrower understands that the L/C Guarantees may require the Lender Group to
indemnify the issuing bank for certain costs or liabilities arising out of
claims by Borrower against such issuing bank. Borrower hereby agrees to
indemnify, save, defend, and hold the Lender Group harmless with respect to any
loss, cost, expense (including reasonable attorneys fees), or liability incurred
by the Lender Group under any L/C Guaranty as a result of the Lender Group's
indemnification of any such issuing bank, other than those resulting from the
gross negligence or willful misconduct of any member of the Lender Group.

                  (c) Borrower hereby authorizes and directs any bank that
issues a letter of credit guaranteed by the Lender Group to deliver to
Administrative Agent all instruments, documents, and other writings and property
received by the issuing bank pursuant to such letter of credit, and to accept
and rely upon Administrative Agent's instructions and agreements with respect to
all matters arising in connection with such letter of credit and the related
application. Borrower may or may not be the "applicant" or "account party" with
respect to such letter of credit.



                                      -41-
<PAGE>   50

                  (d) Any and all charges, commissions, fees, and costs incurred
by Administrative Agent relating to the letters of credit guaranteed by the
Lender Group shall be considered Lender Group Expenses for purposes of this
Agreement and immediately shall be reimbursable by Borrower to Administrative
Agent.

                  (e) Immediately upon the termination of this Agreement,
Borrower agrees to either (i) provide cash collateral to be held by
Administrative Agent in an amount equal to 105% of the maximum amount of the
Lender Group's obligations under outstanding Letters of Credit, or (ii) cause to
be delivered to Administrative Agent releases of all of the Lender Group's
obligations under outstanding Letters of Credit. At Administrative Agent's
discretion, any proceeds of Collateral received by Administrative Agent after
the occurrence and during the continuation of an Event of Default may be held as
the cash collateral required by this Section 2.16(e).

                  (f) If by reason of (i) any change in any applicable law,
treaty, rule, or regulation or any change in the interpretation or application
by any governmental authority of any such applicable law, treaty, rule, or
regulation, or (ii) compliance by the issuing bank or Administrative Agent with
any direction, request, or requirement (irrespective of whether having the force
of law) of any governmental authority or monetary authority including, without
limitation, Regulation D of the Board of Governors of the Federal Reserve System
as from time to time in effect (and any successor thereto):

                                    (A) any reserve, deposit, or similar
requirement is or shall be imposed or modified in respect of any Letters of
Credit issued hereunder, or

                                    (B) there shall be imposed on any Agent, the
issuing bank, or any member of the Lender Group any other condition regarding
any letter of credit, or Letter of Credit, as applicable, issued pursuant
hereto;

and the result of the foregoing is to increase, directly or indirectly, the cost
to the issuing bank or the Lender Group of issuing, making, guaranteeing, or
maintaining any letter of credit, or Letter of Credit, as applicable, or to
reduce the amount receivable in respect thereof by such issuing bank or the
Lender Group, then, and in any such case, the Lender Group may, at any time
within a reasonable period after the additional cost is incurred or the amount
received is reduced, notify Borrower, and Borrower shall pay on demand such
amounts as the issuing bank or Administrative Agent may specify to be necessary
to compensate the issuing bank or the Lender Group for such additional cost or
reduced receipt, together with interest on such amount from the date of such
demand until payment in full thereof at the rate set forth in Section 3.02(a) or
(b), as applicable. The determination by the issuing bank or Administrative
Agent, as the case may be, of any amount due pursuant to this Section 2.16(f),
as set forth in a certificate setting forth the calculation thereof in
reasonable detail, shall, in the absence of manifest or demonstrable error, be
final and conclusive and binding on all of the parties hereto.

                  (g) Participations:

                      (i) Immediately upon issuance of any Letter of Credit in
         accordance with this Section 2.16, each Lender shall be deemed to have



                                      -42-
<PAGE>   51

         irrevocably and unconditionally purchased and received without recourse
         or warranty, an undivided interest and participation in the credit
         support or enhancement provided through Administrative Agent to such
         issuer in connection with the issuance of such Letter of Credit, equal
         to such Lender's Percentage Share of the face amount of such Letter of
         Credit (including, without limitation, all obligations of Borrower with
         respect thereto, and any security therefor or guaranty pertaining
         thereto).

                      (ii) Upon the request of any Lender, Administrative Agent
         shall furnish to such Lender copies of any Letter of Credit,
         reimbursement agreements executed in connection therewith, application
         for any Letter of Credit and credit support or enhancement provided
         through Administrative Agent in connection with the issuance of any
         Letter of Credit, and such other documentation as may reasonably be
         requested by such Lender.

                      (iii) The obligations of each Lender to make payments to
         Administrative Agent with respect to any Letter of Credit or with
         respect to any credit support or enhancement provided through
         Administrative Agent with respect to a Letter of Credit, and the
         obligations of Borrower to make payments to Administrative Agent, for
         the account of the Lenders, shall be irrevocable, not subject to any
         qualification or exception whatsoever, including any of the following
         circumstances:

                                            (A) any lack of validity or
enforceability of this Agreement or any of the other Loan Documents;

                                            (B) the existence of any claim,
setoff, defense or other right which Borrower may have at any time against a
beneficiary named in a Letter of Credit or any transferee of any Letter of
Credit (or any Person for whom any such transferee may be acting), any Lender,
any Agent, the issuer of such Letter of Credit, or any other Person, whether in
connection with this Agreement, any Letter of Credit, the transactions
contemplated herein or any unrelated transactions (including any underlying
transactions between Borrower or any other Person and the beneficiary named in
any Letter of Credit);

                                            (C) any draft, certificate or any
other document presented under the Letter of Credit proving to be forged,
fraudulent, invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect;

                                            (D) the surrender or impairment of
any security for the performance or observance of any of the terms of any of the
Loan Documents; or

                                            (E) the occurrence of any Default or
Event of Default.

                  (h) In the event any payment by or on behalf of Borrower
received by Administrative Agent with respect to any Letter of Credit (or any
guaranty by Borrower or reimbursement obligation of Borrower relating thereto)
and distributed by the Administrative Agent to the Lenders on account of their
respective participations therein, is thereafter set aside,



                                      -43-
<PAGE>   52

avoided or recovered from Administrative Agent in connection with any
receivership, liquidation or bankruptcy proceeding, the Lenders shall, upon
demand by Administrative Agent, pay to Administrative Agent their respective
Percentage Shares of such amount set aside, avoided or recovered, together with
interest at the rate required to be paid by Administrative Agent upon the amount
required to be repaid by it.



                                  ARTICLE III
                       PAYMENTS OF PRINCIPAL AND INTEREST

         Section 3.01. Repayment of Loans. The Borrower will pay to the
Administrative Agent, for the account of each Lender, the entire amount of the
Indebtedness on the Maturity Date.

         Section 3.02. Interest.

                  (a) The Borrower will pay to the Administrative Agent, for
account of each Lender, interest on the unpaid principal amount of each Loan
made by such Lender for the period commencing on the date such Loan is made to
but excluding the date such Loan shall be paid in full, at the Base Rate (as in
effect from time to time) plus the Applicable Margin, but in no event to exceed
the Highest Lawful Rate; provided, however, that, so long as no Default has
occurred and is continuing, that portion, if any, of the Applicable Margin in
excess of 2.00% per annum shall, in the absence of an election by the Borrower
to pay such interest in cash, be paid-in-kind by being added to the principal
balance of the Loans; provided further, however, that the Borrower may, on or
prior to the date that is 5 Business Days prior to the due date thereof, elect
to pay all accrued and unpaid interest under this Section 3.02(a) in cash.

                  (b) Notwithstanding the foregoing, at any time that an Event
of Default has occurred and is continuing, the Borrower will pay to the
Administrative Agent, for the account of each Lender, interest at the applicable
Post-Default Rate on the unpaid principal of each Loan made by such Lender, and
(to the fullest extent permitted by law) on each other amount payable by the
Borrower hereunder or under any other Loan Document to or for account of such
Lender.

                  (c) Accrued interest on Base Rate Loans shall be payable
monthly, in arrears, on the first day of each month and on the Maturity Date.

                                   ARTICLE IV
                PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

         Section 4.01. Payments. Except to the extent otherwise provided herein,
all payments of principal, interest, Letter of Credit fees, and other amounts to
be made by the Borrower under this Agreement and any other Loan Document shall
be made in Dollars, in immediately available funds, to the Administrative Agent
at the Administrative Agent's



                                      -44-
<PAGE>   53

Account, not later than 10:00 a.m. Los Angeles time on the date on which such
payments shall become due (each such payment made after such time on such due
date to be deemed to have been made on the next succeeding Business Day). Such
payments shall be made without (to the fullest extent permitted by applicable
law) defense, set-off or counterclaim, but shall not constitute a waiver,
release or estoppel with respect to any such defense, set-off or counterclaim.
Each payment to be made to the Administrative Agent under this Agreement or any
other Loan Document for account of a Lender shall be paid promptly by
Administrative Agent to such Lender in immediately available funds.

         Section 4.02. Pro Rata Treatment. Except to the extent otherwise
provided herein (or otherwise agreed to between the Lenders), each Lender agrees
that: (i) each borrowing from the Lenders under Section 2.01 shall be made from
each Lender pro rata in accordance with its Percentage Share and each
termination or reduction of the amount of the Aggregate Maximum Credit Amounts
under Section 2.03(b) shall be applied to the Commitment of each Lender, pro
rata in accordance with its Percentage Share; (ii) each payment of principal of
Loans by the Borrower shall be made for account of the Lenders pro rata in
accordance with the respective unpaid principal amount of the Loans held by the
Lenders; (iii) each payment of interest on Loans by the Borrower shall be made
for account of the Lenders pro rata in accordance with the amounts of interest
due and payable to the respective Lenders; and (iv) each reimbursement by the
Borrower of disbursements under Letters of Credit shall be made for account of
the Administrative Agent or, if funded by the Lenders, pro rata for the account
of the Lenders in accordance with the amounts of reimbursement obligations due
and payable to each respective Lender.

         Section 4.03. Computations. Interest on Loans shall be computed on the
basis of a year of 360 days and actual days elapsed (including the first day but
excluding the last day) occurring in the period for which such interest is
payable, unless such calculation would exceed the Highest Lawful Rate, in which
case interest shall be calculated on the per annum basis of a year of 365 or 366
days, as the case may be.

         Section 4.04. Non-receipt of Funds by the Administrative Agent. Unless
the Administrative Agent shall have been notified by a Lender or the Borrower
prior to the date on which such notifying party is scheduled to make payment to
the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or
a payment under a Letter of Credit to be made by it hereunder or (in the case of
the Borrower) a payment to the Administrative Agent for account of one or more
of the Lenders hereunder (such payment being herein called the "Required
Payment"), which notice shall be effective upon receipt, that it does not intend
to make the Required Payment to the Administrative Agent, the Administrative
Agent may assume that the Required Payment has been made and may, in reliance
upon such assumption (but shall not be required to), make the amount thereof
available to the intended recipient(s) on such date; and, if such Lender or the
Borrower (as the case may be) has not in fact made the Required Payment to the
Administrative Agent, the recipient(s) of such payment shall, on demand, repay
to the Administrative Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Administrative Agent until but excluding the



                                      -45-
<PAGE>   54

date the Administrative Agent recovers such amount at a rate per annum which,
for any Lender as recipient, will be equal to the Federal Funds Rate, and for
the Borrower as recipient, will be equal to the Base Rate plus the Applicable
Margin.

         Section 4.05. Set-off- Sharing of Payments, Etc.

                  (a) The Borrower agrees that, in addition to (and without
limitation of) any right of set-off, bankers' lien or counterclaim a Lender may
otherwise have, after the occurrence and during the continuation of a Default,
each Lender shall have the right and be entitled (after consultation with the
Collateral Agent), at its option, to offset balances held by it or by any of its
Affiliates for account of any Obligor at any of its offices, in Dollars or in
any other currency, against any principal of or interest on any of such Lender's
Loans, or any other amount payable to such Lender hereunder, which is not paid
when due (regardless of whether such balances are then due to such Obligor), in
which case it shall promptly notify such Obligor and the Collateral Agent
thereof, provided that such Lender's failure to give such notice shall not
affect the validity thereof.

                  (b) If any Lender shall obtain payment of any principal of or
interest on any Loan made by it to any Obligor under this Agreement or any other
Loan Document through the exercise of any right of set-off, banker's lien or
counterclaim or similar right or otherwise, and, as a result of such payment,
such Lender shall have received a greater percentage of the principal or
interest then due hereunder by the Borrower to such Lender than the percentage
received by any other Lenders, it shall promptly (i) notify the Administrative
Agent and each other Lender thereof and (ii) purchase from such other Lenders
participations in (or, if and to the extent specified by such Lender, direct
interests in) the Loans made by such other Lenders (or in interest due thereon,
as the case may be) in such amounts, and make such other adjustments from time
to time as shall be equitable, to the end that all the Lenders shall share the
benefit of such excess payment (net of any expenses which may be incurred by
such Lender in obtaining, or preserving such excess payment) pro rata in
accordance with the unpaid principal and/or interest on the Loans held by each
of the Lenders. To such end all the Lenders shall make appropriate adjustments
among themselves (by the resale of participations sold or otherwise) if such
payment is rescinded or must otherwise be restored. QSRD and the Borrower agree
that any Lender so purchasing a participation (or direct interest) in the Loans
made by other Lenders (or in interest due thereon, as the case may be) may
exercise all rights of set-off, banker's lien, counterclaim or similar rights
with respect to such participation as fully as if such Lender were a direct
holder of Loans in the amount of such participation. Nothing contained herein
shall require any Lender to exercise any such right or shall affect the right of
any Lender to exercise, and retain the benefits of exercising, any such right
with respect to any other indebtedness or obligation of such Obligor. If under
any applicable bankruptcy, insolvency or other similar law, any Lender receives
a secured claim in lieu of a set-off to which this Section 4.05 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders entitled
under this Section 4.05 to share the benefits of any recovery on such secured
claim.

         Section 4.06. Taxes.

                  (a) Payments Free and Clear. Any and all payments by any
Obligor hereunder or under any other Loan Document shall be made, in accordance
with Section 4.01, free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of each Lender
and the Agents, taxes imposed on its income, and franchise or similar taxes
imposed on it, by (i) any jurisdiction (or political subdivision thereof) of
which the Agents or such Lender, as the case may be, is a citizen or resident
(ii) the jurisdiction (or any political subdivision thereof) in which the Agents
or such Lender is organized, or (iii) any jurisdiction (or political subdivision
thereof) in which such Lender or the Agents is presently doing business which
taxes are imposed solely as a result of doing business in such jurisdiction (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If such Obligor shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Lenders or the Agents: (i) the sum payable shall be increased
by the amount necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 4.06) such
Lender or the Agents (as the case may be) shall receive an amount equal to the
sum it would have received had no such deductions been made, (ii) such Obligor
shall make such deductions and (iii) such Obligor shall pay the full amount
deducted to the relevant taxing authority or other Governmental Authority in
accordance with applicable law.

                  (b) Other Taxes. In addition, to the fullest extent permitted
by applicable law, the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, any
Assignment or any other Loan Document (hereinafter referred to as "Other
Taxes").

                  (c) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE AGENTS FOR THE
FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES
OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER
THIS SECTION 4.06) PAID BY SUCH LENDER OR THE AGENTS (ON THEIR BEHALF OR ON
BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING
PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO,
WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED
UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED AND SUCH
LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF ITS GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT PURSUANT TO SUCH INDEMNIFICATION
SHALL BE MADE WITHIN THIRTY ~30) DAYS



                                      -47-
<PAGE>   56

AFTER THE DATE ANY LENDER OR THE AGENTS, AS THE CASE MAY BE, MAKES WRITTEN
DEMAND THEREFOR. IF ANY LENDER OR THE AGENTS RECEIVES A REFUND OR CREDIT IN
RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER OR THE AGENTS HAS
RECEIVED PAYMENT FROM THE BORROWER IT SHALL PROMPTLY NOTIFY THE BORROWER OF SUCH
REFUND OR CREDIT AND SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN
THIRTY (30) DAYS AFTER RECEIPT OF A REQUEST BY THE BORROWER (OR PROMPTLY UPON
RECEIPT, IF THE BORROWER HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT
PURSUANT HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE BORROWER
WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED), PROVIDED THAT
THE BORROWER, UPON THE REQUEST OF SUCH LENDER OR THE AGENTS, AGREES TO RETURN
SUCH REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER
OR THE AGENTS IN THE EVENT SUCH LENDER OR THE AGENTS ARE REQUIRED TO REPAY SUCH
REFUND OR CREDIT.

                  (d) Lender Representations.

                      (i) Each Lender represents that it is either (i) organized
         under the laws of the United States of America or any state thereof or
         (ii) it is entitled to complete exemption from United States
         withholding tax imposed on or with respect to any payments, including
         fees, to be made to it pursuant to this Agreement and the other Loan
         Documents (A) under an applicable provision of a tax convention to
         which the United States of America is a party or (B) because it is
         acting through a branch, agency or office in the United States of
         America and any payment to be received by it hereunder is effectively
         connected with a trade or business in the United States of America.
         Each Lender that is not a corporation organized under the laws of the
         United States of America or any state thereof agrees to provide to the
         Borrower and the Administrative Agent on the Closing Date, or on the
         date of its delivery of the Assignment pursuant to which it becomes a
         Lender, and at such other times as required by United States law or as
         the Borrower or the Administrative Agent shall reasonably request, two
         accurate and complete original signed copies of either (A) Internal
         Revenue Service Form 4224 (or successor form) certifying that all
         payments to be made to it hereunder will be effectively connected to a
         United States trade or business (the "Form 4224 Certification") or (B)
         Internal Revenue Service Form 1001 (or successor form) certifying that
         it is entitled to the benefit of a provision of a tax convention to
         which the United States of America is a party which completely exempts
         from United States withholding tax all payments to be made to it
         hereunder (the "Form 1001 Certification"). In addition, each Lender
         agrees that if it previously filed a Form 4224 Certification, it will
         deliver to the Borrower and the Administrative Agent a new Form 4224
         Certification prior to the first



                                      -48-
<PAGE>   57

         payment date occurring in each of its subsequent taxable years; and if
         it previously filed a Form 1001 Certification, it will deliver to the
         Borrower and the Administrative Agent a new certification prior to the
         first payment date falling in the third year following the previous
         filing of such certification. Each Lender also agrees to deliver to the
         Borrower and the Administrative Agent such other or supplemental forms
         as may at any time be required as a result of changes in applicable law
         or regulation in order to confirm or maintain in effect its entitlement
         to exemption from United States withholding tax on any payments
         hereunder, provided that the circumstances of such Lender at the
         relevant time and applicable laws permit it to do so. If a Lender
         determines, as a result of any change in either (i) a Governmental
         Requirement or (ii) its circumstances, that it is unable to submit any
         form or certificate that it is obligated to submit pursuant to this
         Section 4.06, or that it is required to withdraw or cancel any such
         form or certificate previously submitted, it shall promptly notify the
         Borrower and the Administrative Agent of such fact. If a Lender is
         organized under the laws of a jurisdiction outside the United States of
         America, unless the Borrower and the Administrative Agent have received
         a Form 1001 Certification or Form 4224 Certification satisfactory to
         them indicating that all payments to be made to such Lender hereunder
         are not subject to United States withholding tax, the Administrative
         Agent (in consultation with the Borrower) shall withhold taxes from
         such payments at the applicable statutory rate. Each Lender agrees to
         indemnify and hold harmless from any United States taxes, penalties,
         interest and other expenses, costs and losses incurred or payable by
         (i) the Borrower or the Administrative Agent as a result of such
         Lender's failure to submit any form or certificate that it is required
         to provide pursuant to this Section 4.06 or (ii) the Borrower or the
         Administrative Agent as a result of their reliance on any such form or
         certificate which such Lender has provided to them pursuant to this
         Section 4.06.

                      (ii) For any period with respect to which a Lender has
         failed to provide the Borrower with the form required pursuant to this
         Section 4.06, if any (other than if such failure is due to a change in
         a Governmental Requirement occurring subsequent to the date on which a
         form originally was required to be provided), such Lender shall not be
         entitled to indemnification under Section 4.06 with respect to taxes
         imposed by the United States which taxes would not have been imposed
         but for such failure to provide such forms; provided, however, that
         should a Lender, which is otherwise exempt from or subject to a reduced
         rate of withholding tax becomes subject to taxes because of its failure
         to deliver a form required hereunder, the Borrower shall take such
         steps as such Lender shall reasonably request to assist such Lender to
         recover such taxes.

                      (iii) Any Lender claiming any additional amounts payable
         pursuant to this Section 4.06 shall use reasonable efforts (consistent
         with legal



                                      -49-
<PAGE>   58

         and regulatory restrictions) to file any certificate or document
         requested by the Borrower or the Administrative Agent or to change the
         jurisdiction of its lending office or to contest any tax imposed if the
         making of such a filing or change or contesting such tax would avoid
         the need for or reduce the amount of any such additional amounts that
         may thereafter accrue and would not, in the sole determination of such
         Lender, be otherwise disadvantageous to such Lender.

         Section 4.07. Disposition of Proceeds . The Security Instruments
contain an assignment unto and in favor of the Collateral Agent for the benefit
of the Lenders of all production and all proceeds attributable thereto which may
be produced from or allocated to the Mortgaged Property, and the Security
Instruments further provide in general for the application of such proceeds to
the satisfaction of the Indebtedness and other obligations described therein and
secured thereby. Notwithstanding the assignment contained in such Security
Instruments, until the occurrence of an Event of Default, the Lenders agree that
they will neither notify the purchaser or purchasers of such production nor take
any other action to cause such proceeds to be remitted to the Lenders, but the
Lenders will instead permit such proceeds to be paid to QSRD and its
Subsidiaries. In addition, until the occurrence of an Event of Default, the
Lenders will, upon written request of the Borrower given to the Collateral
Agent, execute and deliver, at the Borrower's expense, such transfer orders and
other instruments reasonably necessary to allow payment of production proceeds
directly to QSRD and its Subsidiaries.

of the jurisdiction of its incorporation; (ii) has all requisite corporate
power, and has all material governmental licenses, authorizations, consents and

in which the nature of the business conducted by it makes such qualification
necessary and where failure so to qualify would have a Material Adverse Effect.

                  (b) Set forth on Schedule 7.01, is a complete and accurate
description of the authorized capital Stock of Borrower, by class, and, as of
the Closing Date, a description of the number of shares of each such class that
are issued and outstanding and the number of such shares that are held in
Borrower's treasury. All such outstanding shares have been validly issued and,
as of the Closing Date, are fully paid, nonassessable shares free of contractual
preemptive rights. The issuance and sale of all such shares have been in
compliance with all applicable federal and state securities laws. Other than as
described on Schedule 7.01, there are no subscriptions, options, warrants, or
calls relating to any shares of Borrower's capital Stock, including any right of
conversion or exchange under any outstanding security or other instrument.
Neither Borrower nor any of its Subsidiaries is subject to any obligation
(contingent or otherwise) to repurchase or otherwise acquire or retire any
shares of its capital Stock or any security convertible into or exchangeable for
any of its capital Stock.

                  (c) Set forth on Schedule 7.01, is a complete and accurate
list of Borrower's direct and indirect Subsidiaries as of the Closing Date,
showing: (i) the jurisdiction of their incorporation; (ii) the number of shares
of each class of common and preferred Stock authorized for each of such
Subsidiaries; and (iii) the number and the percentage of the outstanding shares
of each such class owned directly or indirectly by Borrower. All of the
outstanding capital Stock of each such Subsidiary has been validly issued and is
fully paid and non-assessable. As of the Closing Date, Borrower has no interest
in any partnerships (other than tax partnerships which are not partnerships
under applicable state law). QSR Canada has no assets in excess of $200,000 in
the aggregate or liabilities in excess of $150,000 in the aggregate, and its
business operations are limited to providing general and administrative
services, including management services, to QSRD and its Subsidiaries.

                  (d) Except as set forth on Schedule 7.01, no capital Stock (or
any securities, instruments, warrants, options, purchase rights, conversion or
exchange rights, calls, commitments or claims of any character convertible into
or exercisable for capital Stock) of any direct or indirect Subsidiary of
Borrower is subject to the issuance of any security, instrument, warrant,
option, purchase right, conversion or exchange right, call, commitment or claim
of any right, title, or interest therein or thereto.

         Section 7.02. Financial Condition.

                  (a) The audited consolidated balance sheet of QSRD and its
Consolidated Subsidiaries, as at June 30, 1999 and the related consolidated
statement of operations, stockholders' equity and cash flow of QSRD and its
Consolidated Subsidiaries, for the fiscal year ended on said date, with the
audit report thereon of Ernst & Young L.L.P. heretofore furnished to each of the
Lenders, and the unaudited consolidated balance sheet of QSRD and its
Consolidated Subsidiaries as at August 31, 1999 and their related consolidated
statements of operations, and cash flow of QSRD and its Consolidated
Subsidiaries for the 2-month period ended on such date heretofore furnished to
the Lenders are complete and correct in all material respects and fairly present
the consolidated financial condition of QSRD and its Consolidated Subsidiaries
as at said dates and the results of its operations for the fiscal year



                                      -55-
<PAGE>   64

and the 2-month period ending on said dates, in accordance with GAAP with
respect to the audited financial statements, and on a modified accrual basis
with respect to interim financial statements, in each case applied on a
consistent basis (subject, in the case of the interim financial statements, to
normal year-end adjustments).

                  (b) Neither QSRD nor any of its Subsidiaries has on the
Closing Date any material Debt, contingent liabilities interpreted in accordance
with GAAP, liabilities for taxes, unusual forward or long-term commitments for
the purchase or sale of Oil and Gas Properties, or unrealized or anticipated
losses from any unfavorable commitments, in each case except for customary
purchase price adjustments, prorations, indemnities, and other typical
obligations arising under or in connection with the purchase or sale of Oil and
Gas Properties or the acquisition or issuance of securities, and except as
referred to or reflected or provided for in the Financial Statements or in
Schedule 7.02 which could reasonably be expected to have a Material Adverse
Effect. Since June 30, 1999, there has been no change or event having a Material
Adverse Effect. Since June 30, 1999, neither the business nor the Properties of
QSRD or any of its Subsidiaries have been materially and adversely affected as a
result of any fire, explosion, earthquake, flood, drought, windstorm, accident,
strike or other labor disturbance, embargo, requisition or taking of Property or
cancellation of contracts, permits or concessions by any Governmental Authority,
riot, activities of armed forces or acts of God or of any public enemy.

         Section 7.03. Litigation. Except as disclosed to the Lenders in
Schedule 7.03 hereto, at the Closing Date there is no litigation, legal,
administrative or arbitration proceeding, investigation or other action of any
nature pending or, to the knowledge of QSRD and the Borrower threatened against
or affecting QSRD or any of its Subsidiaries which involves the possibility of
any judgment or liability against QSRD or any of its Subsidiaries not fully
covered by insurance (except for normal deductibles), and which would have a
Material Adverse Effect.

         Section 7.04. No Breach. Neither the execution and delivery of the Loan
Documents nor compliance with the terms and provisions hereof will conflict with
or result in a breach of, or require any consent which has not been obtained as
of the Closing Date or which if not obtained would have a Material Adverse
Effect under, the respective charter or by-laws of QSRD or any of its
Subsidiaries, including the Borrower, or any material Governmental Requirement,
agreement or instrument to which QSRD or any of its Subsidiaries, including the
Borrower, is a party or by which it is bound or to which it or its Properties
are subject, or constitute a default under any such agreement or instrument, or
result in the creation or imposition of any Lien upon any of the revenues or
assets of QSRD or any of its Subsidiaries, including the Borrower, pursuant to
the terms of any such agreement or instrument other than the Liens created by
the Loan Documents.

         Section 7.05. Authority. QSRD and each of its Subsidiaries, including
the Borrower, have all necessary corporate power and authority to execute,
deliver and perform its obligations under the Loan Documents to which it is a
party; and the execution, delivery and performance by QSRD and each of its
Subsidiaries, including the Borrower, of the Loan



                                      -56-
<PAGE>   65

Documents to which it is a party have been duly authorized by all necessary
corporate action on its part; and the Loan Documents constitute the legal, valid
and binding obligations of each such Person, enforceable against it in
accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization or other similar laws affecting creditors' rights and general
principles of equity.

         Section 7.06. Approvals. No authorizations, approvals or consents of,
and no filings or registrations with, any Governmental Authority are necessary
for the execution, delivery or performance by QSRD or any of its Subsidiaries,
including the Borrower, of the Loan Documents or for the validity or
enforceability thereof.

         Section 7.07. Use of Loans. The proceeds of the Loans shall be used for
general corporate purposes (consistent with the covenants contained herein and
in the other Loan Documents), including the following: i) to meet the Borrower's
capital expenditure requirements, ii) to finance Permitted Acquisitions, and
iii) to repay, in full, the DEM Subordinated Debt (in a maximum amount of DEM
1,700,000). The Borrower is not engaged principally, or as one of its important
activities, in the business of extending credit for the purpose, whether
immediate, incidental or ultimate, of buying or carrying margin stock (within
the meaning of Regulation T, U or X of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan or Letter of Credit
hereunder will be used to buy or carry any margin stock.

         Section 7.08. ERISA.

                  (a) QSRD and its ERISA Affiliates have complied in all
material respects with ERISA and, where applicable, the Code regarding each
Plan.

                  (b) Each Plan is, and has been, maintained in substantial
compliance with ERISA and, where applicable, the Code.

                  (c) To the best knowledge of QSRD, no act, omission or
transaction has occurred which could result in imposition on QSRD or any of its
ERISA Affiliates (whether directly or indirectly) of (i) either a civil penalty
assessed pursuant to section 502(c), (i) or (1) of ERISA or a tax imposed
pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary
duty liability damages under section 4.09 of ERISA.

                  (d) No Plan (other than a defined contribution plan) or any
trust created under any such Plan has been terminated since September 2, 1974.
No liability to the PBGC (other than for the payment of current premiums which
are not past due) by QSRD or any of its ERISA Affiliates has been or is expected
by QSRD to be incurred with respect to any Plan. No ERISA Event with respect to
any Plan has occurred.

                  (e) Full payment when due has been made of all amounts which
QSRD and/or its ERISA Affiliates is required under the terms of each Plan or
applicable law to have paid as contributions to such Plan, and no accumulated
funding deficiency (as defined in



                                      -57-
<PAGE>   66

section 302 of ERISA and section 412 of the Code), whether or not waived, exists
with respect to any Plan.

                  (f) The actuarial present value of the benefit liabilities
under each Plan which is subject to Tide IV of ERISA does not, as of the end of
QSRD's most recently ended fiscal year, exceed the current value of the assets
(computed on a plan termination basis in accordance with Title IV of ERISA) of
such Plan allocable to such benefit liabilities. The term "actuarial present
value of the benefit liabilities" shall have the meaning specified in section
4041 of ERISA.

                  (g) None of QSRD or its ERISA Affiliates sponsors, maintains,
or contributes to an employee welfare benefit plan, as defined in section 3(l)
of ERISA, including, without limitation, any such plan maintained to provide
benefits to former employees of such entities, that may not be terminated by
QSRD or any of its ERISA Affiliates in its sole discretion at any time without
any material liability.

                  (h) None of QSRD or its ERISA Affiliates sponsors, maintains
or contributes to, or has at any time in the preceding six calendar years,
sponsored, maintained or contributed to, any Multiemployer Plan.

                  (i) None of QSRD or its ERISA Affiliates is required to
provide security under section 401(a)(29) of the Code due to a Plan amendment
that results in an increase in current liability for the Plan.

         Section 7.09. Taxes. Each of QSRD and its Subsidiaries, including the
Borrower, has filed all required United States Federal income tax returns that
are currently due and, to the best of QSRD's knowledge, all other tax returns
which are required to be filed by them and have paid all material taxes due
pursuant to such returns or pursuant to any assessment received by QSRD or any
of its Subsidiaries, including the Borrower, except for those being contested in
good faith by appropriate proceedings and for which adequate reserves have been
provided in accordance with GAAP. The charges, accruals and reserves on the
books of QSRD and its Subsidiaries in respect of taxes and other governmental
charges are, in the opinion of QSRD, adequate. No tax Lien has been filed and,
to the knowledge of QSRD, no claim is being asserted with respect to any such
tax, fee or other charge which could reasonably be expected to have a Material
Adverse Effect.

         Section 7.10. Titles, etc.

                  (a) Except as set out in Schedule 7.10, each of QSRD and its
Subsidiaries has good and defensible title to its material (individually or in
the aggregate) Properties, free and clear of all Liens except Liens permitted by
Section 9.02. Except as set forth in Schedule 7.10, after giving full effect to
the Excepted Liens, QSRD and its Subsidiaries, as applicable, owns the net
interests in production attributable to the lands and leases reflected in the
most recently delivered Reserve Report and the ownership of such Properties
shall not in any material respect obligate such Person to bear the costs and
expenses relating to the maintenance, development and operations of each such
Property in an amount in excess of



                                      -58-
<PAGE>   67

the working interest of each Property set forth in the most recently delivered
Reserve Report. All information contained in the most recently delivered Reserve
Report is true and correct in all material respects as of the date thereof.

                  (b) All material leases and agreements necessary for the
conduct of the business of QSRD and its Subsidiaries are valid and subsisting
and are in full force and effect. There exists no default or event or
circumstance which with the giving of notice or the passage of time or both
would give rise to a default under any such lease or leases which would affect
in any material respect the conduct of the business of QSRD and its Subsidiaries
taken as a whole or which would have a Material Adverse Effect.

                  (c) The rights, properties and other assets presently owned,
leased or licensed by QSRD and its Subsidiaries including, without limitation,
all easements and rights of way, include all rights, Properties and other assets

business in all material respects in the same manner as its business has been
conducted prior to the Closing Date.

                  (d) All of the assets and Properties of QSRD and its
Subsidiaries which are reasonably necessary for the operation of its business
are in good working condition and are maintained in accordance with prudent
business standards.

         Section 7.11. No Material Misstatements. No written information,
statement, exhibit, certificate, document or report furnished to the Agents or
the Lenders (or any of them) by QSRD or any of its Subsidiaries in connection
with the negotiation of this Agreement contained any material misstatement of
fact or omitted to state a material fact or any fact necessary to make the
statement contained therein not materially misleading in the light of the
circumstances in which made. There is no fact known to QSRD which has a Material
Adverse Effect or in the future is reasonably likely to have (so far as QSRD can
now foresee) a Material Adverse Effect and which has not been set forth in this
Agreement or the other documents, certificates and statements furnished to the
Agents by or on behalf of QSRD or any of its Subsidiaries prior to, or on, the
Closing Date in connection with the transactions contemplated hereby.

         Section 7.12. Investment Company Act. Neither QSRD nor any of its

"holding company," or a "subsidiary company" of a "holding company," or an
"affiliate" of a "holding company" or of a "subsidiary company" of a "holding
company," or a "public utility" within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

         Section 7.14. Subsidiaries and Partnership. Except as set forth on
Schedule 7.14, as such Schedule shall from time to time be revised to reflect
the creation of additional Subsidiaries by QSRD or the Borrower or their
Subsidiaries in accordance with Section 9.17,



                                      -59-
<PAGE>   68

QSRD has no Subsidiaries and has no interest in any partnerships; and the
Borrower has no Subsidiaries and has no interest in any partnerships. Schedule
7.14 sets forth the principal place of business of each such Subsidiary and the
ownership interest of QSRD and the Borrower in such Subsidiary.

         Section 7.15. Location of Business and Offices. Each of QSRD and the
Borrower's principal place of business and chief executive offices are located
at the address stated on the signature page of this Agreement. The principal
place of business and chief executive office of each Subsidiary are located at
the addresses stated on Schedule 7.14.

         Section 7.16. Defaults. Neither QSRD nor any of its Subsidiaries is in
default nor has any event or circumstance occurred which, but for the expiration
of any applicable grace period or the giving of notice, or both, would
constitute a default under any Material Agreement to which any such Person is a
party or by which any such Person is bound which default would have a Material
Adverse Effect. No Default hereunder has occurred and is continuing.

         Section 7.17. Environmental Matters. Except (i) as provided in Schedule
7.17 or (ii) as would not have a Material Adverse Effect (or with respect to
(c), (d) and (e) below, where the failure to take such actions would not have a
Material Adverse Effect):

                  (a) Neither any Property of QSRD or any of its Subsidiaries
nor the operations conducted thereon violate any order or requirement of any
court or Governmental Authority or any Environmental Laws.

                  (b) Without limitation of clause (a) above, no Property of
QSRD or any of its Subsidiaries nor the operations currently conducted thereon
or, to the best knowledge of QSRD, by any prior owner or operator of such
Property or operation, are in violation of or subject to any existing, pending
or (to the knowledge of QSRD) threatened action, suit, investigation, inquiry or
proceeding by or before any court or Governmental Authority or to any remedial
obligations under Environmental Laws.

                  (c) All notices, permits, licenses or similar authorizations,
if any, required to be obtained or filed in connection with the operation or use
of any and all Property of QSRD and each of its Subsidiaries, including without
limitation past or present treatment, storage, disposal or release of a
hazardous substance or solid waste into the environment, have been duly obtained
or filed, and QSRD and each of its Subsidiaries are in compliance with the terms
and conditions of all such notices, permits, licenses and similar
authorizations.

                  (d) All hazardous substances, solid waste, and oil and gas
exploration and production wastes, if any, generated at any and all Property of
QSRD or any of its Subsidiaries have in the past been transported, treated and
disposed of in accordance with Environmental Laws and so as not to pose an
imminent and substantial endangerment to public health or welfare or the
environment, and, to the best knowledge of QSRD, all such transport carriers and
treatment and disposal facilities have been and are operating in compliance with
Environmental Laws and so as not to pose an imminent and substantial



                                      -60-
<PAGE>   69

endangerment to public health or welfare or the environment, and are not the
subject of any existing, pending or (to the knowledge of QSRD) threatened
action, investigation or inquiry by any Governmental Authority in connection
with any Environmental Laws.

                  (e) QSRD has taken all steps reasonably necessary to determine
and has determined that no hazardous substances, solid waste, or oil and gas
exploration and production wastes, have been disposed of or otherwise released
and there has been no threatened release of any hazardous substances on or to
any Property of QSRD or any of its Subsidiaries except in compliance with
Environmental Laws and so as not to pose an imminent and substantial
endangerment to public health or welfare or the environment.

                  (f) To the extent applicable, all Property of QSRD and each of
its Subsidiaries currently satisfies all design, operation, and equipment
requirements imposed by OPA or scheduled as of the Closing Date to be imposed by
OPA during the term of this Agreement, and QSRD does not have any reason to
believe that such Property, to the extent subject to OPA, will not be able to
maintain compliance with the OPA requirements during the term of this Agreement.

                  (g) Neither QSRD nor any of its Subsidiaries has any known
contingent liability in connection with any release or threatened release of any
oil, hazardous substance or solid waste into the environment.

         Section 7.18. Compliance with the Law. Neither QSRD nor any of its
Subsidiaries has violated any Governmental Requirement or failed to obtain any
license, permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties or the conduct of its business, which
violation or failure would have (in the event such violation or failure were
asserted by any Person through appropriate action) a Material Adverse Effect.
Except for such acts, or failures to act as would not have a Material Adverse
Effect, the Oil and Gas Properties (and Properties unitized therewith) have been
maintained, operated and developed in a good and workmanlike manner and in
substantial conformity with all applicable laws and all rules, regulations and
orders of all duly constituted authorities having jurisdiction and in
substantial conformity with the provisions of all leases, subleases or other
contracts comprising a part of the Hydrocarbon Interests and other contracts and
agreements forming a part of the Oil and Gas Properties; specifically in this
connection, (i) after the Closing Date, no Oil and Gas Property is subject to
having allowable production reduced below the full and regular allowable
(including the maximum permissible tolerance) because of any overproduction
(whether or not the same was permissible at the time) prior to the Closing Date
and (ii) none of the wells comprising a part of the Oil and Gas Properties (or
properties unitized therewith) are deviated from the vertical more than the
maximum permitted by applicable laws, regulations, rules and orders, and such
wells are, in fact, bottomed under and are producing from, and the well bores
are wholly within, the Oil and Gas Properties (or in the case of wells located
on Properties unitized therewith, such unitized Properties).

         Section 7.19. Insurance. Schedule 7.19 attached hereto contains an
accurate and complete description of all material policies of fire, liability,
workmen's compensation and other forms of insurance owned or held by QSRD and
each of its Subsidiaries. All such policies are in full force and effect, all
premiums with respect thereto covering all periods up to and including the
Closing Date have been paid, and no notice of cancellation or termination has
been received with respect to any such policy. Such policies are sufficient for
substantial compliance with all requirements of law and of all agreements to
which QSRD or any of its Subsidiaries is a party; are valid, outstanding and
enforceable policies; provide adequate insurance coverage in at least such
amounts and against at least such risks (but including in any event public
liability) as are usually insured against in the same general area by similarly
situated companies engaged in the same or a similar business for the assets and
operations of QSRD and each of its Subsidiaries; will remain in full force and
effect through the respective dates set forth in Schedule 7.19 without the
payment of additional premiums; and will not in any way be affected by, or
terminate or lapse by reason of, the transactions contemplated by this
Agreement. Schedule 7.19 identifies all material risks, if any, which QSRD and
its Subsidiaries and their respective Board of Directors or officers have
designated as being self insured. Neither QSRD nor any of its Subsidiaries has
been refused any insurance with respect to its assets or operations, nor has its
coverage been limited below usual and customary policy limits, by an insurance
carrier to which it has applied for any such insurance or with which it has
carried insurance during the last three years.

         Section 7.20. Risk Management Agreements. Schedule 7.20 sets forth, as
of the Closing Date, a true and complete list of all Risk Management Agreements
(including commodity price swap agreements, forward agreements or contracts of
sale which provide for prepayment for deferred shipment or delivery of oil, gas
or other commodities) of QSRD and each of its Subsidiaries, the material terms
thereof (including the type, term, effective date, termination date and notional
amounts or volumes), all credit support agreements relating thereto (including
any margin required or supplied), and the counterparty to each such agreement.

         Section 7.21. Restriction on Liens. Except as set forth on Schedule
7.21, neither QSRD nor any of its Subsidiaries (other than Non-Recourse
Subsidiaries) is a party to any agreement or arrangement or subject to any
order, judgment, writ or decree, which either restricts or purports to restrict
its ability to grant Liens to other Persons on or in respect of their respective
assets or Properties; provided that such restrictions do not impair the ability
of QSRD or any of its Subsidiaries (other than Non-Recourse Subsidiaries) to
grant Liens to the Collateral Agent for the benefit of the Lender Group.

         Section 7.22. Gas Imbalances. Except as set forth on Schedule 7.22 or
on the most recent certificate delivered pursuant to Section 8.07(c), on a net
basis there are no gas imbalances, take or pay or other prepayments with respect
to QSRD and its Subsidiaries' Oil and Gas Properties which would require such
Person to either make cash settlements for such production or deliver
Hydrocarbons produced from such Oil and Gas Properties at some future time
without then or thereafter receiving full payment therefor exceeding five
percent



                                      -62-
<PAGE>   71

(5%) of the then current monthly production of gas from the Oil and Gas
Properties of QSRD and its Subsidiaries in the aggregate.

         Section 7.23. Material Agreements.

                  (a) Set forth on Schedule 7.23 hereto is a complete and
correct list of all Material Agreements in effect or to be in effect as of the
Closing Date (other than Risk Management Agreements) providing for, evidencing,
securing or otherwise relating to any Debt of QSRD or any of its Subsidiaries,
and such list correctly sets forth the names of the debtor or lessee and
creditor or lessor with respect to the Debt or lease obligations outstanding or
to be outstanding and the Property subject to any Lien securing such Debt or
lease obligation. Also set forth on Schedule 7.23 hereto is a complete and
correct list of all material agreements and other instruments of QSRD and its
Subsidiaries relating to the purchase, transportation by pipeline, gas
processing, marketing, sale and supply of natural gas and other Hydrocarbons,
but in any event, any such agreement or other instrument that will account for
more than 20% of the sales of QSRD and its Subsidiaries during QSRD's current
fiscal year.

                  (b) QSRD has delivered to the Agents true and complete copies
of each of the agreements evidencing the Subordinated Debt and each Material
Agreement, as each may have been amended, that have been requested by the
Agents.

         Section 7.24. Solvency. QSRD and its Consolidated Subsidiaries, taken
as a whole, (i) are not insolvent as of the date hereof and will not be rendered
insolvent as a result of the transactions contemplated by this Agreement and the
other Loan Documents, (ii) are not engaged in business or a transaction, or
about to engage in a business or a transaction, for which any Property or assets
remaining with QSRD and its Consolidated Subsidiaries constitutes unreasonably
small capital, and (iii) do not intend to incur, or believe any of them will
incur, debts that will be beyond their ability to pay as such debts mature.

         Section 7.25. Brokerage Fees. Except for any and all brokerage fees
payable by Borrower to Durham Capital Corporation ("Durham") on the Closing Date
for the services rendered to Borrower by Durham, no brokerage commission or
finders fees has or shall be incurred or payable in connection with or as a

                  (e) In the event that all or any portion of any Oil and Gas
Property owned by QSRD and its Subsidiaries is composed of interests in the

Properties at some future time without then or thereafter receiving full



                                      -70-
<PAGE>   79

payment therefor, (iv) none of its Oil and Gas Properties have been sold since

                  (d) As soon as available and in any event within 45 days after
the end of each fiscal quarter, the Borrower shall provide (i) a production
report, in the form currently prepared internally by the Borrower and which has
been approved by the Administrative Agent, and (ii) a summary of all general and
administrative costs of QSRD and its Consolidated Subsidiaries for such quarter
which are not reflected in the Consolidated Net Income for such quarter for its
Oil and Gas Properties, which reports shall include quantities or volume of
production, revenue, realized product prices, operating expenses, taxes, capital
expenditures and lease operating costs which have accrued to the account of
QSRD, the Borrower or any Subsidiary (other than Non-Recourse Subsidiaries) in
such period, and such other information with respect thereto as the Agents or
any Lender may reasonably require.

                  (e) As soon as available and in any event within 30 days after
the end of each month ending after the Closing Date, a report setting forth, in
form reasonably acceptable to the Agents, the revaluation of the PV-10 Value of
the oil and gas reserves composing the Borrowing Base as determined by the most
recently delivered Reserve Report provided by Borrower under Section 8.07(a) or
(b), as applicable, such revaluation calculated by multiplying the volumetric
quantity of the categories of estimated Proved Reserves provided in such Reserve
Report less aggregate projected production of Proved Reserves since the date of
and as provided in such Reserve Report by the applicable NYMEX Swap Price as of
last Business Day of the month preceding the date of the delivery by Borrower of
such report to the Agents; each such monthly report shall also include a
discussion of any changes since the date of the most recent Reserve Report in

revenue interest in the Oil and Gas Properties, and such other information as
the Administrative Agent shall reasonably consider appropriate or necessary from
the perspective of an asset-based lender; each such monthly report shall be
accompanied by a certificate of a Responsible Officer of the Borrower certifying
to the completeness and accuracy of the report including the calculations of the
revalued Proved Reserves.

         Section 8.08. Title Information.

                  (a) On or before the delivery to the Agent and the Lenders of
each Reserve Report required by Section 8.07(a) or (b), as applicable, the
Borrower will deliver title information in form and substance reasonably
satisfactory to the Administrative Agent



                                      -71-
<PAGE>   80

covering the Oil and Gas Properties evaluated by such Reserve Report and
included in the Borrowing Base that were not included in the immediately
preceding Borrowing Base evaluation, so that the Administrative Agent shall have
received together with title information previously delivered to the
Administrative Agent, satisfactory title information on at least 85% of the
PV-10 Value of the Oil and Gas Properties (to include 100% of the Principal
Properties) evaluated by such Reserve Report and included in the Borrowing Base.
The Borrower shall cure any title defects or exceptions which are not Excepted
Liens raised by the title information within 60 days after a request by the
Administrative Agent or the Lenders to cure such defects or exceptions.

                  (b) If the Borrower is unable to cure any title defect
requested by the Administrative Agent or the Lenders to be cured within the 60
day period, such default shall not be a Default or an Event of Default, but
instead the Administrative Agent and the Lenders shall have the right to
exercise the following remedy in their sole discretion from time to time, and
any failure to so exercise this remedy at any time shall not be a waiver as to
future exercise of the remedy by the Administrative Agent or the Lenders. To the
extent that the Administrative Agent or the Lenders are not satisfied with title
to any Oil and Gas Property after the time period in Section 8.08(a) has
elapsed, such unacceptable Oil and Gas Property shall not count towards the 85%
requirement (or the 100% of Principal Properties requirement), and the
Administrative Agent may send a notice to the Borrower and the Lenders that the
then outstanding Borrowing Base shall be reduced by an amount as determined by
all of the Lenders to cause the Borrower to be in compliance with the
requirement to provide acceptable title information on 85% of the PV-10 Value of
the Oil and Gas Properties (including 100% of the Principal Properties) included
in the Borrowing Base. This new Borrowing Base shall become effective
immediately after receipt of such notice.

         Section 8.09. Additional Collateral.

                  (a) QSRD and the Borrower will, and will cause each Subsidiary
Guarantor to, grant to the Collateral Agent as security for the Indebtedness a
first-priority Lien (subject only to Excepted Liens and to the extent
applicable, Liens permitted by Section 9.02) on such Person's interest in any
Oil and Gas Properties not already subject to a Lien of the Security Instruments
such that the Mortgaged Property shall include at least 85% (including 100% of
the Principal Properties) (and will use reasonable efforts to maintain 95%
(including 100% of the Principal Properties)) of its and such Subsidiaries'
PV-10 Value of each of proved producing and the total Proved Reserves at all
times, which Lien will be created and perfected by and in accordance with the
provisions of deeds of trust, security agreements and financing statements, or

principal of, or make any other payment in relation to, the Senior Notes;
provided, so long as no Borrowing Base deficiency then exists under Section

occurred and is continuing or would result therefrom, the foregoing shall not
prohibit (i) the payment of interest on the Senior Notes, (ii) the repayment of
the Senior Notes with the proceeds of any refinancing thereof (provided that
such refinancing Debt is on terms substantially similar to the Senior Notes),
(iii) modifications or amendments to the Senior Notes or the Senior Note

aggregate during any 12 month period, on a cumulative basis for the first 12
months commencing July 1, 1999, and for each 12 month period ending at the end
of each month thereafter, $12,000,000, or (ii) in the aggregate, for the period

                  (k) the occurrence of a Change of Control.

         Section 10.02. Remedies. If any Event of Default shall have occurred

                                   ARTICLE XI
                                    THE AGENT

         Section 11.01. Appointment, Powers and Immunities.

                  (a) Each member of the Lender Group hereby designates and
appoints Administrative Agent as its administrative agent under this Agreement
and the other Loan Documents and Collateral Agent as its collateral agent under
this Agreement and the other Loan Documents. Each member of the Lender Group
hereby irrevocably authorizes each such Agent to take such action on its behalf
under the provisions of this Agreement and each other Loan Document and to
exercise such powers and perform such duties as are expressly delegated to it by
the terms of this Agreement or any other Loan Document, together with such
powers as are reasonably incidental thereto. Each such Agent agrees to act as
such on the express conditions contained in this Article XI. The provisions of
this Article XI are solely for the benefit of the Administrative Agent,
Collateral Agent, and the Lenders. No Obligor shall have any rights as a third
party beneficiary of any of the provisions contained herein. Any provision to
the contrary contained elsewhere in this Agreement or in any other Loan Document
notwithstanding, each such Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall each such Agent have or be
deemed to have any fiduciary relationship with any other member of the Lender
Group, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against each such Agent; it being expressly
understood and agreed that the use of the word "Agent" is for convenience only
and that each such Agent is merely the representative



                                      -85-
<PAGE>   94

of the other members of the Lender Group, and has only the contractual duties
set forth in this Agreement and the other Loan Documents. Except as expressly
otherwise provided in this Agreement, each such Agent shall have and may use its
sole discretion with respect to exercising or refraining from exercising any
discretionary rights or taking or refraining from taking any actions which such
Agent is expressly entitled to take or assert under or pursuant to this
Agreement and the other Loan Documents. No member of the Lender Group shall have
any right of action whatsoever against each such Agent as a result of such Agent
acting or failing to act hereunder pursuant to such discretion (other than any
action taken or failure to act arising out of such Agent's gross negligence or
willful misconduct) and any such action taken or failure to act pursuant to such
discretion shall be binding on the Lender Group. Without limiting the generality
of the foregoing, or of any other provision of the Loan Documents that provides
rights or powers to Administrative Agent or Collateral Agent, each of the
members of the Lender Group agree that, as long as this Agreement remains in
effect: (i) (A) Administrative Agent shall have the right to maintain, in
accordance with its customary business practices, ledgers and records reflecting
the status of the Indebtedness, the Loans, the Letters of Credit, payments made
by the Borrower, and related matters, and (B) Collateral Agent shall have the
right to maintain, in accordance with its customary business practices, ledgers
and records reflecting the status of the Collateral and related matters; (ii)
Collateral Agent shall have the right to execute or file any and all financing
or similar statements or notices, amendments, renewals, supplements, documents,
instruments, proofs of claim, notices and other written agreements with respect
to the Loan Documents; (iii) Administrative Agent shall have the right to make
the Loans, and the Letters of Credit, for itself or on behalf of the applicable
Lenders as provided in the Loan Documents; (iv) [intentionally omitted]; (v)
[intentionally omitted]; (vi) (A) Administrative Agent shall have the right to
perform, exercise, and enforce any and all other rights and remedies of the
Lender Group with respect to the Obligors, the Indebtedness, or otherwise
related to any of same to the extent reasonably incidental to the exercise by
Administrative Agent of the rights and remedies specifically authorized to be
exercised by Administrative Agent by the terms of the Loan Documents, and (B)
Collateral Agent shall have the right to perform, exercise, and enforce such
other rights and remedies of the Lender Group with respect to the Obligors, the
Indebtedness, the Collateral, or otherwise related to any of same to the extent
reasonably incidental to the exercise by Collateral Agent of the rights and
remedies specifically authorized to be exercised by Collateral Agent by the
terms of the Loan Documents ; and (vii) Administrative Agent and Collateral
Agent each shall have the right to incur and pay such fees and Lender Group
Expenses under the Loan Documents as such Agent reasonably may deem necessary or
appropriate for the performance and fulfillment of its functions and powers
pursuant to the Loan Documents. Administrative Agent may deem and treat the
payee of any Indebtedness as the holder thereof for all purposes of the Loan
Documents unless and until a notice of the assignment or transfer of such
Indebtedness shall have been filed with Administrative Agent. Each member of the
Lender Group further consents to (y) the execution, delivery, and performance by
Administrative Agent or Collateral Agent of each Loan Document entered into by
such Agent on behalf of the Lender Group as contemplated by this Agreement, and
(z) the terms of such Loan Documents.

                  (b) Except as otherwise provided in this section, each of
Administrative Agent and Collateral Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. Each of Administrative Agent and



                                      -86-
<PAGE>   95

Collateral Agent shall not be responsible for the negligence or misconduct of
any agent or attorney-in-fact that it selects as long as such selection was made
in compliance with this section and without gross negligence or willful
misconduct.

                  (c) None of the Agent-Related Persons shall (i) be liable for
any action taken or omitted to be taken by any of them under or in connection
with this Agreement or any other Loan Document or the transactions contemplated
hereby (except for its own gross negligence or willful misconduct), or (ii) be
responsible in any manner to any members of the Lender Group for any recital,
statement, representation or warranty made by any Obligor or any Subsidiary or
Affiliate thereof, or any officer or director thereof, contained in this
Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by
Administrative Agent or Collateral Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any Obligor or any other party to any Loan
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any member of the Lender Group to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Obligor or any
of its Subsidiaries or Affiliates.

         Section 11.02. Reliance by Agent. Each Agent shall be entitled to rely,
and shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, facsimile, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent, or made by the proper Person,
and upon advice and statements of legal counsel (including counsel to the
Obligors or counsel to any member of the Lender Group), independent accountants
and other experts selected by such Agent. Each Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it first shall receive such advice or concurrence of the Lenders
as it deems appropriate and until such instructions are received, such Agent
shall act, or refrain from acting, as it deems advisable. If any Agent so
requests, it first shall be indemnified to its reasonable satisfaction by the
Lender Group against any and all liability and expense that may be incurred by
it by reason of taking or continuing to take any such action. Each Agent in all
cases shall be fully protected in acting, or in refraining from acting, under
this Agreement or any other Loan Document in accordance with a request or
consent of the Lender Group and such request and any action taken or failure to
act pursuant thereto shall be binding upon all members of the Lender Group.

         Section 11.03. Defaults. Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest, fees, and
Lender Group Expenses required to be paid to Administrative Agent for the
account of the Lender Group or the failure of Borrower to reimburse for Letter
of Credit drawings, except with respect to Events of Default of which
Administrative Agent has actual knowledge, and unless Administrative Agent shall
have received written notice from a Lender or Borrower referring to this
Agreement, describing such Default or Event of Default, and stating that such
notice is a



                                      -87-
<PAGE>   96

"Notice of Default." Administrative Agent promptly will notify the Lender Group
of its receipt of any such notice or of any Event of Default of which
Administrative Agent has actual knowledge. If any Lender obtains actual
knowledge of any Event of Default, such Lender promptly shall notify the other
Lenders and each Agent of such Event of Default. Each Lender shall be solely
responsible for giving any notices to its Participants, if any. Subject to
Sections 11.02 and 11.07, each Agent shall take such action with respect to such
Default or Event of Default as may be requested by the Required Lenders in
accordance with Article X; provided, however, that unless and until such Agent
has received any such request, such Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable.

         Section 11.04. Rights as a Lender.

                  (a) With respect to its Commitment and the Loans made by it
and its participation in the issuance of Letters of Credit, Foothill Capital
Corporation (and any successor acting as Administrative Agent, if any, as
permitted by Section 11.08(a) hereof) in its capacity as a Lender under the Loan
Documents shall have the same rights, privileges and powers under the Loan
Documents as any other Lender and may exercise the same as though it were not
acting as Administrative Agent, and the term "Lender" or "Lenders" shall, unless
the context otherwise indicates, include Administrative Agent in its individual
capacity. Foothill Capital Corporation (and any successor acting as
Administrative Agent) and its affiliates may (without having to account for the
same to any member of the Lender Group) accept deposits from, lend money to,
make investments in and generally engage in any kind of banking, trust or other
business with Borrower (and any of its Subsidiaries or Affiliates) as if it were
not acting as Administrative Agent, and Foothill Capital Corporation (and its
successors) and its affiliates may accept fees and other consideration from
Borrower for services in connection with this Agreement or otherwise without
having to account for the same to the Lender Group.

                  (b) With respect to its Commitment and the Loans made by it,
Ableco Finance LLC (and any successor acting as Collateral Agent, if any, as
permitted by Section 11.08(b) hereof) in its capacity as a Lender under the Loan
Documents shall have the same rights, privileges and powers under the Loan
Documents as any other Lender and may exercise the same as though it were not
acting as Collateral Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include Collateral Agent in its individual
capacity. Ableco Finance LLC (and any successor acting as Collateral Agent) and
its affiliates may (without having to account for the same to any member of the
Lender Group) accept deposits from, lend money to, make investments in and
generally engage in any kind of banking, trust or other business with Borrower
(and any of its Subsidiaries or Affiliates) as if it were not acting as
Collateral Agent, and Ableco Finance LLC and its affiliates may accept fees and
other consideration from Borrower for services in connection with this Agreement
or otherwise without having to account for the same to the Lender Group.

         Section 11.05. COSTS AND EXPENSES; INDEMNIFICATION. EACH AGENT MAY
INCUR AND PAY FEES, COSTS, AND LENDER GROUP EXPENSES UNDER THE LOAN DOCUMENTS TO
THE EXTENT SUCH AGENT DEEMS



                                      -88-
<PAGE>   97

REASONABLY NECESSARY OR APPROPRIATE FOR THE PERFORMANCE AND FULFILLMENT OF ITS
FUNCTIONS, POWERS, AND OBLIGATIONS PURSUANT TO THE LOAN DOCUMENTS, INCLUDING
WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, COURT COSTS, REASONABLE
ATTORNEYS FEES AND EXPENSES, COSTS OF COLLECTION BY OUTSIDE COLLECTION AGENCIES
AND AUCTIONEER FEES AND COSTS OF SECURITY GUARDS OR INSURANCE PREMIUMS PAID TO
MAINTAIN THE COLLATERAL, WHETHER OR NOT BORROWER IS OBLIGATED TO REIMBURSE THE
LENDER GROUP FOR SUCH EXPENSES PURSUANT TO THE LOAN AGREEMENT OR OTHERWISE. EACH
LENDER HEREBY AGREES THAT IT IS AND SHALL BE OBLIGATED TO PAY TO OR REIMBURSE
AGENT FOR THE AMOUNT OF SUCH LENDER'S PERCENTAGE SHARE THEREOF. WHETHER OR NOT
THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED, THE LENDERS SHALL
INDEMNIFY UPON DEMAND THE AGENT-RELATED PERSONS (WITHOUT LIMITING THE OBLIGATION
OF THE OBLIGORS TO DO SO), ACCORDING TO THEIR PERCENTAGE SHARES, FROM AND
AGAINST ANY AND ALL INDEMNIFIED LIABILITIES (INCLUDING WITHOUT LIMITATION
INDEMNIFIED LIABILITIES ARISING UNDER ANY ENVIRONMENTAL LAW AS PROVIDED HEREIN);
PROVIDED, HOWEVER, THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT TO THE
AGENT-RELATED PERSONS OF ANY PORTION OF SUCH INDEMNIFIED LIABILITIES RESULTING
SOLELY FROM SUCH PERSON'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT
LIMITATION OF THE FOREGOING, EACH LENDER SHALL REIMBURSE ADMINISTRATIVE AGENT OR
COLLATERAL AGENT, AS THE CASE MAY BE, UPON DEMAND FOR SUCH LENDER'S RATABLE
SHARE OF ANY COSTS OR OUT-OF-POCKET EXPENSES (INCLUDING ATTORNEYS FEES AND
EXPENSES) INCURRED BY SUCH AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION,
DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER
THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS OR OTHERWISE) OF, OR LEGAL ADVICE IN
RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THIS AGREEMENT, ANY OTHER LOAN
DOCUMENT, OR ANY DOCUMENT CONTEMPLATED BY OR REFERRED TO HEREIN . THE
UNDERTAKING IN THIS SECTION SHALL SURVIVE THE PAYMENT OF ALL INDEBTEDNESS AND
OTHER OBLIGATIONS HEREUNDER AND THE RESIGNATION OR REPLACEMENT OF ANY AGENT.

                  Section 11.06. Non-Reliance on Agent and other Lenders. Each
Lender acknowledges that none of the Agent-Related Persons has made any
representation or warranty to it, and that no act by any Agent hereinafter
taken, including any review of the affairs or Property of the Obligors and their
Subsidiaries or Affiliates, shall be deemed to constitute any representation or
warranty by any Agent-Related Person to any Lender. Each Lender represents to
each Agent that it has, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it has
deemed



                                      -89-
<PAGE>   98

appropriate, made its own appraisal of and investigation into the business,
prospects, operations, Property, financial and other condition and
creditworthiness of QSRD and its Subsidiaries, including the Borrower, and any
other Person (other than the Lender Group) party to a Loan Document, and all
applicable bank regulatory laws relating to the transactions contemplated
hereby, and made its own decision to enter into this Agreement and to extend
credit to Borrower. Each Lender also represents that it will, independently and
without reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of Borrower and any
other Person (other than the Lender Group) party to a Loan Document. Except for
notices, reports and other documents expressly herein required to be furnished
to the Lender Group by an Agent, no Agent shall have any duty or responsibility
to provide any member of the Lender Group with any credit or other information
concerning the business, prospects, operations, Property, financial and other
condition or creditworthiness of QSRD and its Subsidiaries, including the
Borrower, and any other Person (other than the Lender Group) party to a Loan
Document that may come into the possession of any of the Agent-Related Persons.

         Section 11.07. Action by Agents. Except for action or other matters
expressly required of any Agent hereunder, such Agent shall in all cases be
fully justified in failing or refusing to take any action under this Agreement
or any other Loan Document unless it shall (i) receive written instructions from
the Majority Lenders specifying the action to be taken, and (ii) be indemnified
to its satisfaction by the Lenders against any and all liability and expenses
which may be incurred by it by reason of taking, not taking or continuing to
take any such action. The instructions of the Majority Lenders and any action
taken or failure to act pursuant thereto by such Agent shall be binding on all
of the Lenders. If a Default has occurred and is continuing, such Agent shall
take such action with respect to such Default as shall be directed by the
Majority Lenders in the written instructions (with indemnities) described in
this Section 11.07, provided that, unless and until such Agent shall have
received such directions, such Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default as
it shall deem advisable in the best interests of the Lenders. In no event,
however, shall any Agent be required to take any action which exposes such Agent
to personal liability or which is contrary to this Agreement and the Loan
Documents or applicable law.

         Section 11.08. Resignation or Removal of Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, Administrative Agent may resign at any time by notice to the Lender Group
and Borrower (for the benefit of the Obligors). Upon any such resignation, the
Majority Lenders shall have the right to appoint a successor Administrative
Agent. If no successor Administrative Agent shall have been appointed by the
Majority Lenders and have accepted such appointment within 30 days after the
retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of Lenders, appoint a successor
Administrative Agent. Upon the acceptance of



                                      -90-
<PAGE>   99

any appointment as Administrative Agent by a successor Administrative Agent,
such successor Administrative Agent shall thereupon succeed to and become vested
with all the rights, remedies, powers, privileges, duties and obligations of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations, under the Loan Documents. After any
retiring Administrative Agent's resignation as Administrative Agent, the
provisions of this Article XI and Section 12.03 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent. If no successor Administrative Agent has
accepted appointment as Administrative Agent by the date which is 45 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless become effective and the
Majority Lenders shall perform all of the duties of Administrative Agent until
such time, if any, as the Majority Lenders appoint a successor Administrative
Agent as provided above.

                  (b) Subject to the appointment and acceptance of a successor
Collateral Agent as provided below, Collateral Agent may resign at any time by
notice to the Lender Group and Borrower (for the benefit of the Obligors). Upon
any such resignation, the Majority Lenders shall have the right to appoint a
successor Collateral Agent. If no successor Collateral Agent shall have been
appointed by the Majority Lenders and have accepted such appointment within 30
days after the retiring Collateral Agent's giving of notice of resignation, then
the retiring Collateral Agent may, on behalf of Lenders, appoint a successor
Collateral Agent. Upon the acceptance of any appointment as Collateral Agent by
a successor Collateral Agent, such successor Collateral Agent shall thereupon
succeed to and become vested with all the rights, remedies, powers, privileges,
duties and obligations of the retiring Collateral Agent, and the retiring
Collateral Agent shall be discharged from its duties and obligations, under the
Loan Documents. After any retiring Collateral Agent's resignation as Collateral
Agent, the provisions of this Article XI and Section 12.03 shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken by
it while it was acting as Collateral Agent. If no successor Collateral Agent has
accepted appointment as Collateral Agent by the date which is 45 days following
a retiring Collateral Agent's notice of resignation, the retiring Collateral
Agent's resignation shall nevertheless become effective and the Majority Lenders
shall perform all of the duties of Collateral Agent until such time, if any, as
the Majority Lenders appoint a successor Collateral Agent as provided above.

         Section 11.09. Collateral Sub-Agents. Each member of the Lender Group
by its execution and delivery of this Agreement (or any joinder hereto or any
Assignment hereunder) agrees that, in the event it shall hold any monies or
other investments on account of Borrower or any other Obligor, such monies or
other investments shall be held in the name and under the control of such member
of the Lender Group, and such member of the Lender Group shall hold such monies
or other investments as a collateral sub-agent for Collateral Agent under this
Agreement and the other Loan Documents. Each Obligor by its execution and
delivery of this Agreement hereby consents to the foregoing.

         Section 11.10. Communications by Obligors. Except as otherwise provided
in this Agreement, the Obligors' communications with respect to the Loan
Documents shall be with Administrative Agent or Collateral Agent, as the case
may be, and the Obligors shall not be under any obligation to communicate
directly with the Lenders.

         Section 11.11. Collateral Matters.

                  (a) The Lenders hereby irrevocably authorize Collateral Agent,
at its option and in its sole discretion, to release any Lien on any Collateral
(i) upon the termination of the Commitments and payment and satisfaction in full
of all Indebtedness; (ii) constituting property being sold or disposed of if a
release is required or desirable in connection therewith and if Borrower
certifies in writing to Collateral Agent that the sale or disposition is
permitted under this Agreement or the other Loan Documents (and Collateral Agent
may rely conclusively on any such certificate, without further inquiry); (iii)
constituting property in which Borrower and the other Obligors owned no interest
at the time the security interest was granted or at any time thereafter; (iv)
constituting property leased to Borrower or any other Obligor under a lease that
has expired or is terminated in a transaction permitted under this Agreement, or
(v) which, in the aggregate with all other dispositions of Collateral, has a
fair market value or book value, whichever is less, of $1,000,000 or less.
Except as provided above or expressly provided in any other Loan Document,
Collateral Agent will not execute and deliver a release of any Lien on any
Collateral without the prior written authorization of all of the Lenders. Upon
request by Collateral Agent or Borrower at any time, Administrative Agent and
the Lenders will confirm in writing Collateral Agent's authority to release any
such Liens on particular types or items of Collateral pursuant to this Section
11.11; provided, however, that (1) Collateral Agent shall not be required to
execute any document necessary to evidence such release on terms that, in
Collateral Agent's opinion, would expose Collateral Agent to liability or create
any obligation or entail any consequence other than the release of such Lien
without recourse, representation, or warranty, and (2) such release shall not in
any manner discharge, affect, or impair the Indebtedness or any Liens (other
than those expressly being released) upon (or obligations of Borrower or the
other Obligors in respect of) all interests retained by Borrower or the other
Obligors, including, the proceeds of any sale, all of which shall continue to
constitute part of the Collateral.

                  (b) Collateral Agent shall have no obligation whatsoever to
any other member of the Lender Group to assure that the Collateral exists or is
owned by Borrower or any other Obligor or is cared for, protected, or insured or
has been encumbered, or that the Collateral Agent's Liens have been properly or
sufficiently or lawfully created, perfected, protected, or enforced or are
entitled to any particular priority, or to exercise at all or in any particular
manner or under any duty of care, disclosure or fidelity, or to continue
exercising, any of the rights, authorities and powers granted or available to
Collateral Agent pursuant to any of the Loan Documents, it being understood and
agreed that in respect of the Collateral, or any act, omission or event related
thereto, subject to the terms and conditions contained herein, Collateral Agent
may act in any manner it may deem appropriate, absent the Collateral Agent's
gross negligence or willful misconduct, in its sole discretion given Collateral
Agent's own interest in the Collateral in its capacity as one of the Lenders and
that Collateral Agent shall have no other duty or liability whatsoever to any
other member of the Lender Group as to any of the foregoing, except as otherwise
provided herein.

         Section 11.12. Restrictions on Actions by the Agents and the Lenders;
Sharing Payments.

<PAGE>   101

                  (a) Each of the Agents and each of the Lenders agrees that it
shall not, without the express consent of the Agents, and that it shall, to the
extent it is lawfully entitled to do so, upon the request of Collateral Agent,
set off against the Indebtedness, any amounts owing by such member of the Lender
Group to Borrower or any other Obligor or any accounts of Borrower or any other
Obligor now or hereafter maintained with such member of the Lender Group. Each
of the Agents and each of the Lenders further agrees that it shall not, unless
specifically requested to do so by Collateral Agent , take or cause to be taken
any action, including, the commencement of any legal or equitable proceedings,
to foreclose any Lien on, or otherwise enforce any security interest in, any of
the Collateral the purpose of which is, or could be, to give such member of the
Lender Group any preference or priority against the other members of the Lender
Group with respect to the Collateral.

                  (b) Subject to Section 11.04, if, at any time or times any
Lender shall receive (i) by payment, foreclosure, setoff or otherwise, any
proceeds of Collateral or any payments with respect to the Indebtedness arising
under, or relating to, this Agreement or the other Loan Documents, except for
any such proceeds or payments received by such Lender from Administrative Agent
pursuant to the terms of this Agreement, or (ii) payments from Administrative
Agent in excess of such Lender's ratable portion of all such distributions by
Administrative Agent, such Lender promptly shall turn the same over to
Administrative Agent, in kind, and with such endorsements as may be required to
negotiate the same to Administrative Agent, or in same day funds, as applicable,
for the account of the Lender Group and for apportionment and application to the
Indebtedness in accordance with Section 2.14 hereof.

         Section 11.13. Several Obligations; No Liability. Notwithstanding that
certain of the Loan Documents now or hereafter may have been or will be executed
only by or in favor of an Agent in its capacity as such, and not by or in favor
of the Lenders, any and all obligations on the part of Administrative Agent (if
any) to make any credit available hereunder shall constitute the several (and
not joint) obligations of the respective Lenders on a ratable basis, according
to their Percentage Shares, to make an amount of such credit not to exceed, in
principal amount, at any one time outstanding, the amount of their respective
Commitments. Nothing contained herein shall confer upon any member of the Lender
Group any interest in, or subject any member of the Lender Group to any
liability for, or in respect of, the business, assets, profits, losses, or
liabilities of any other member of the Lender Group. Each Lender shall be solely
responsible for notifying its participants of any matters relating to the Loan
Documents to the extent any such notice may be required, and no member of the
Lender Group shall have any obligation, duty, or liability to any participant of
any other Lender. Except as provided in Section 11.05, no Agent or any Lender
shall have any liability for the acts of the other Agent or any other Lender. No
Lender shall be responsible to Borrower, any other Obligor, or any other Person
for any failure by any other Lender to fulfill its obligations to make credit
available hereunder, nor to advance for it or on its behalf in connection with
its Commitment, nor to take any other action on its behalf hereunder or in
connection with the financing contemplated herein.

Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any of the Loan Documents shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under any of the Loan Documents preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.

                  (d) NO INDEMNIFIED PARTY MAY SETTLE ANY CLAIM TO BE
INDEMNIFIED WITHOUT THE CONSENT OF THE INDEMNITOR, SUCH CONSENT NOT TO BE
UNREASONABLY WITHHELD; PROVIDED, THAT THE INDEMNITOR MAY NOT REASONABLY WITHHOLD
CONSENT TO ANY SETTLEMENT THAT AN INDEMNIFIED PARTY PROPOSES IF THE INDEMNITOR

successors and permitted assigns.

         Section 12.06. Assignments and Participations.

                  (a) Borrower shall maintain, or cause to be maintained, a
register (the "Register") on which it enters the name of each Lender as the
registered owner of the Loans held by such Lender. A Registered Loan (and the
Registered Note, if any, evidencing the same) may be assigned or sold in whole
or in part only by registration of such assignment or sale on the Register (and
each Registered Note shall expressly so provide). Any assignment or sale of all
or part of such Registered Loan (and the Registered Note, if any, evidencing the
same) may be effected only by registration of such assignment or sale on the
Register, together with the surrender of the Registered Note, if any, evidencing
the same duly endorsed by (or accompanied by a written instrument of assignment
or sale duly executed by) the holder of such Registered Note, whereupon, at the
request of the designated assignee(s) or transferee(s), one or more new
Registered Notes in the same aggregate principal amount shall be issued to the
designated assignee(s) or transferee(s). Prior to the registration of assignment
or sale of any Registered Loan (and the Registered Note, if any evidencing the
same), the Borrower shall treat the Person in whose name such Loan (and the
Registered Note, if any, evidencing the same) is registered as the owner thereof
for the purpose of receiving all payments thereon and for all other purposes,
notwithstanding notice to the contrary.

                  (b) In the event that any Lender sells participations in the
Registered Loan, such Lender shall maintain a register on which it enters the
name of all participants in the Registered Loans held by it (the "Participant
Register"). A Registered Loan (and the Registered Note, if any, evidencing the
same) may be participated in whole or in part only by registration of such
participation on the Participant Register (and each Registered Note shall
expressly so provide). Any participation of such Registered Loan (and the
Registered Note, if any, evidencing the same) may be effected only by the
registration of such participation on the Participant Register.

<PAGE>   106

                  (c) No Obligor, including the Borrower, may assign its rights
or obligations hereunder or under any other Loan Documents without the prior
consent of all of the Lenders and the Agents.

                  (d) Any Lender may, upon the written consent of the Agents
and, unless an Event of Default has occurred and is continuing, the written
consent Borrower (which consent will not be unreasonably withheld and which
consent is not required for assignments to Affiliates of a Lender), assign to
one or more assignees all or a portion of its rights and obligations under this
Agreement pursuant to an Assignment Agreement substantially in the form of
Exhibit E-1 (an "Assignment") provided, however, that (i) any such assignment
shall be in the amount of at least $5,000,000 or such lesser amount to which the
Borrower has consented and (ii) the assignee shall pay to the Administrative
Agent a processing and recordation fee of $5,000 for each assignment. Any such
assignment will become effective upon the execution and delivery to the
Administrative Agent of the Assignment and the consent of the Agents. Promptly
after receipt of an executed Assignment, the Administrative Agent shall send to
the Borrower a copy of such executed Assignment. Upon the effectiveness of any
assignment pursuant to this Section 12.06(b), the assignee will become a
"Lender," if not already a "Lender," for all purposes of this Agreement and the
Security Instruments. The assignor shall be relieved of its obligations
hereunder to the extent of such assignment (and if the assigning Lender no
longer holds any rights or obligations under this Agreement, such assigning
Lender shall cease to be a "Lender" hereunder except that its rights under
Sections 4.06 and 12.03 shall not be affected). The Administrative Agent will
prepare on the last Business Day of each month during which an assignment has
become effective pursuant to this Section 12.06(b), a new Schedule C-1 giving
effect to all such assignments effected during such month, and will promptly
provide the same to the Borrower and each of the Lenders. Anything contained
herein to the contrary notwithstanding, the consent of the Agents or the
Borrower shall not be required (and payment of any fees shall not be required)
if such assignment is in connection with any merger, consolidation, sale,
transfer, or other disposition of all or any substantial portion of the business
or loan portfolio of such Lender or the assignee is an Affiliate (other than
individuals) of, or a fund, money market account, investment account or other
account managed by, a Lender.

                  (e) Each Lender may transfer, grant or assign participations
in all or any part of such Lender's interests hereunder pursuant to this Section
12.06(e) to any Person, provided that: (i) such Lender shall remain a "Lender"
for all purposes of this Agreement and the transferee of such participation
shall not constitute a "Lender" hereunder; and (ii) no participant under any
such participation shall have rights to approve any amendment to or waiver of
any of the Loan Documents except to the extent such amendment or waiver would
(w) forgive or reduce the amount of principal due hereunder, (x) extend the
Revolving Credit Termination Date or the Maturity Date, (y) reduce the interest
rate (other than as a result of waiving the applicability of any post-default
increases in interest rates) or fees applicable to any of the Commitments or
Loans in which such participant is participating, or postpone the payment of any
thereof, or (z) release all or substantially all of the Collateral or any
guarantor (except as expressly provided herein or in any Loan Document)
supporting any of the Commitments or Loans in which such participant is
participating. In the case of any such



                                      -98-
<PAGE>   107

participation, the participant shall not have any rights under this Agreement or
any of the Loan Documents (the participant's rights against the granting Lender
in respect of such participation to be those set forth in the agreement with
such Lender creating such participation), and all amounts payable by the
Borrower hereunder shall be determined as if such Lender had not sold such
participation, provided that such participant shall be entitled to be
indemnified under Section 12.03 as if it were a Lender. In addition, each
agreement creating any participation must include an agreement by the
participant to be bound by the provisions of Section 12.15.

                  (f) The Lenders may furnish any information concerning the
Obligors in the possession of the Lenders from time to time to assignees and
participants (including prospective assignees and participants); provided that,
such Persons agree to be bound by the provisions of Section 12.15 hereof.

                  (g) Notwithstanding anything in this Section 12.06 to the
contrary, any Lender may assign and pledge its portion of the Indebtedness to
any Federal Reserve Bank or the United States Treasury as collateral security
pursuant to Regulation A of the Board of Governors of the Federal Reserve System
and any operating circular issued by such Federal Reserve System and/or such
Federal Reserve Bank. No such assignment and/or pledge shall release the
assigning and/or pledging Lender from its obligations hereunder.

                  (h) Notwithstanding any other provisions of this Section
12.06, no transfer or assignment of the interests or obligations of any Lender
or any grant of participations therein shall be permitted if such transfer,
assignment or grant would require QSRD or the Borrower to file a registration
statement with the SEC or to qualify the Loans under the "Blue Sky" laws of any
state.

         Section 12.07. Invalidity. In the event that any one or more of the
provisions contained in any of the Loan Documents shall, for any reason, be held
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of this Agreement or any
other Loan Document.

         Section 12.08. Counterparts. Each Loan Document may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument and any of the parties hereto may execute this Agreement by
signing any such counterpart.

         Section 12.09. References. The words "herein," "hereof," "hereunder"
and other words of similar import when used in this Agreement refer to this
Agreement as a whole, and not to any particular article, section or subsection.
Any reference herein to a Section shall be deemed to refer to the applicable
Section of this Agreement unless otherwise stated herein. Any reference herein

collateral are subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid to a trustee, debtor in
possession, receiver or other Person under any bankruptcy law, common law or
equitable cause, then to such extent, the Indebtedness so satisfied shall be
revived and continue as if such payment or proceeds had not been received and
the Collateral Agent's Liens, security interests, rights, powers and remedies
under this Agreement and each Loan Document shall continue in full force and
effect. In such event, each Loan Document shall be automatically reinstated and
QSRD and the Borrower shall take and shall cause each Subsidiary Guarantor to

to effect such reinstatement.

DELIVERED AT AND SHALL BE DEEMED TO HAVE BEEN MADE IN NEW YORK, NEW YORK. THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK; PROVIDED, HOWEVER, THAT IF ANY OF THE COLLATERAL SHALL BE
LOCATED IN ANY JURISDICTION OTHER THAN NEW YORK, THE LAWS OF SUCH JURISDICTION
SHALL GOVERN THE METHOD, MANNER, AND PROCEDURE FOR FORECLOSURE OF COLLATERAL
AGENT'S LIEN UPON SUCH COLLATERAL AND THE ENFORCEMENT OF THE LENDER GROUP'S
OTHER REMEDIES IN RESPECT OF SUCH COLLATERAL TO THE EXTENT THAT THE LAWS OF SUCH

BE MADE UPON BOTH QSRD AND BORROWER BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO
BORROWER AT THE ADDRESS SET FORTH IN THIS AGREEMENT AND THAT SERVICE SO MADE
SHALL BE DEEMED COMPLETED UPON THE EARLIER OF BORROWER'S ACTUAL RECEIPT THEREOF
OR 3 DAYS AFTER DEPOSIT IN THE U.S. MAIL, PROPER POSTAGE PREPAID. NOTHING IN
THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO AFFECT THE RIGHT OF THE LENDER
GROUP TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW, OR TO
PRECLUDE THE ENFORCEMENT BY THE LENDER GROUP OF ANY JUDGMENT OR ORDER OBTAINED
IN SUCH FORUM OR THE TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SAME

                  (b) EACH OF QSRD, THE BORROWER AND EACH LENDER HEREBY (I)
IRREVOCABLY AND UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW,
TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR
ANY SECURITY INSTRUMENT AND FOR ANY COUNTERCLAIM THEREIN; (II) IRREVOCABLY
WAIVE, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO
CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR
CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES;
(III) CERTIFY THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL
FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT
SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVERS, AND (IV) ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER INTO THIS
AGREEMENT, THE SECURITY INSTRUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND
THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED
IN THIS SECTION 12.13.

         Section 12.14. Interest. It is the intention of the parties hereto that
the Agent or each Lender shall conform strictly to usury laws applicable to it.
Accordingly, if the transactions contemplated hereby or by any other Loan
Document would be usurious as to the Agent or



                                     -101-
<PAGE>   110

any Lender under laws applicable to it-(including the laws of the United States
of America and the State of New York or any other jurisdiction whose laws may be
mandatorily applicable to such Lender notwithstanding the other provisions of
this Agreement), then, in that event, notwithstanding anything to the contrary
in any of the Loan Documents or any agreement entered into in connection with or
as security for the Indebtedness, it is agreed as follows: (i) the aggregate of
all consideration which constitutes interest under law applicable to the Agents
or any Lender that is contracted for, taken, reserved, charged or received by
the Agents or such Lender under any of the Loan Documents or agreements or
otherwise in connection with the Indebtedness shall under no circumstances
exceed the maximum amount allowed by such applicable law, and any excess shall
be canceled automatically and if theretofore paid shall be credited by the Agent
or such Lender on the principal amount of the Indebtedness (or, to the extent
that the principal amount of the Indebtedness shall have been or would thereby
be paid in full, refunded by the Agent or such Lender, as applicable, to the
Borrower); and (ii) in the event that the maturity of the Indebtedness is
accelerated by reason of any Event of Default under this Agreement or otherwise,
or in the event of any required or permitted prepayment, then such consideration
that constitutes interest under law applicable to the Agents or any Lender may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Agreement or otherwise shall be
canceled automatically by the Agents or such Lender, as applicable, as of the
date of such acceleration or prepayment and, if theretofore paid, shall be
credited by the Agents or such Lender, as applicable, on the principal amount of
the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by the
Agents or such Lender to the Borrower). All sums paid or agreed to be paid to
the Agents or any Lender for the use, forbearance or detention of sums due
hereunder shall, to the extent permitted by law applicable to the Agents or such
Lender, be amortized, prorated, allocated and spread throughout the full term of
the Loans until payment in full so that the rate or amount of interest on
account of any Loans hereunder does not exceed the maximum amount allowed by
such applicable law. If at any time and from time to time (i) the amount of
interest payable to the Agents or any Lender on any date shall be computed at
the Highest Lawful Rate applicable to the Agents or such Lender pursuant to this
Section 12.14 and (ii) in respect of any subsequent interest computation period
the amount of interest otherwise payable to the Agents or such Lender would be
less than the amount of interest payable to the Agents or such Lender computed
at the Highest Lawful Rate applicable to the Agents or such Lender, then the
amount of interest payable to the Agents or such Lender in respect of such
subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to the Agents or such Lender until the total
amount of interest payable to the Agents or such Lender shall equal the total
amount of interest which would have been payable to the Agents or such Lender if
the total amount of interest had been computed without giving effect to this
Section 12.14

         For purposes of this Section 12.14, the term "applicable law" shall
mean that law in effect from time to time and applicable to the loan transaction
between Borrower and the Lender Group that lawfully permits the charging and
collection of the highest permissible, lawful non-usurious rate of interest on
such loan transaction and this Agreement, including laws of the State of New
York and, to the extent controlling, laws of the United States of



                                     -102-
<PAGE>   111

America. It is intended that, in the event that, notwithstanding the parties'
express choice of other law to be applicable to this Agreement, the laws of the
State of Texas are included in determining applicable law, Chapters 301 through
306 of the Texas Finance Code shall be included in any such determination, and
that, for the purpose of applying the Texas Finance Code to this Agreement, the
maximum interest rate shall be the "weekly ceiling" (as such term is used in
Chapter 303 of the Texas Finance Code) from time to time in effect. Any Lender
may, from time to time, as to current and future balances, implement any other
ceiling under Chapter 303 of the Texas Finance Code by notice to Borrower, if
and to the extent permitted by Chapter 303 of the Texas Finance Code. The
parties hereto expressly agree, pursuant to Section 346.004 of the Texas Finance
Code, that Chapter 346 of the Texas Finance Code shall not apply to this
Agreement or to any Loan and that neither this Agreement nor any Loan shall be
governed by or subject to the provisions of Chapter 346 in any manner
whatsoever.

         The right to accelerate the maturity of the Indebtedness does not
include the right to accelerate any interest that has not accrued as of the date
of acceleration.

         Section 12.15. Confidentiality. Each member of the Lender Group agrees
(on behalf of itself and each of its affiliates, directors, officers, employees
and representatives) to use reasonable precautions to keep confidential, in
accordance with its customary procedures for handling confidential information
of this nature and in accordance with safe and sound practices of comparable
commercial finance companies, the Confidential Information and to use reasonable
precautions to prevent such member of the Lender Group's unauthorized use of the
Confidential Information; provided, however, that nothing herein shall limit the
disclosure of any Confidential Information (a) to the extent required by
statute, rule, regulation or judicial process, (b) (i) to any other member of
the Lender Group, (ii) to counsel for such member of the Lender Group on a "need
to know" basis if such disclosure is reasonably determined by the disclosing
party to be reasonably necessary to such Person in connection with the
Indebtedness or the Loan Documents or the transactions contemplated thereunder,
or (iii) to counsel for any other member of the Lender Group on a "need to know"
basis if such disclosure is reasonably determined by the disclosing party to be
reasonably necessary to such Person in connection with the Indebtedness or the
Loan Documents or the transactions contemplated thereunder, (c) to examiners,
auditors, accountants or Securitization Parties on a "need to know" basis if
such disclosure is reasonably determined by the disclosing party to be
reasonably necessary to such Person in connection with the Indebtedness or the
Loan Documents or the transactions contemplated thereunder and the disclosing
party is reasonably certain that such Person will hold the Confidential
Information in confidence as if such Person were bound by confidentiality
provisions similar in substance to this Section 12.15 in all material respects,
(d) in connection with any litigation to which the Lender Group is a party, (e)
to any assignee or participant (or prospective assignee or participant) so long
as such assignee or participant (or prospective assignee or participant) first
agrees, in writing, to be bound by confidentiality provisions similar in
substance to this Section 12.15 in all material respects, or (f) pursuant to the
sale of the relevant Collateral by the Lender Group in connection with the
exercise of the Lender Group's remedies upon the occurrence and during the
continuation of an Event of Default.



                                     -103-
<PAGE>   112

The Lender Group agrees that, upon receipt of a request or identification of the
requirement for disclosure pursuant to clauses (a) or (d) hereof, it will make
reasonable efforts to keep Borrower on behalf of the Obligors informed of such
request or identification (and, unless prohibited by applicable law, statute,
regulation, or court order, concurrently with, or where practicable, prior to
the disclosure thereof); provided, however, that each Obligor acknowledges that
the Lender Group may make disclosure as required or requested by any
Governmental Authority or representative thereof and that the Lender Group may
be subject to review by Securitization Parties or other regulatory agencies and
may be required to provide to, or otherwise make available for review by, the
representatives of such parties or agencies any such non-public information, and
that Borrower shall be kept informed reasonably of such requests and review of
Confidential Information.

         Section 12.16. EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS

ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND RAS RECEIVED
THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT
IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT
IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION
OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD
NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT
"CONSPICUOUS."

         Section 12.17. Designated Senior Indebtedness. QSRD and the Borrower
hereby designate all Indebtedness outstanding under this Agreement and the other
Loan Documents to be "Designated Senior Indebtedness" (as defined in the
Offering Memorandum dated July 15, 1995 relating to the DEM Subordinated Debt)
for purposes of the DEM Subordinated Debt and to be "designated senior
indebtedness," "guarantor senior indebtedness," "designated guarantor senior
indebtedness" or any other similar or equivalent classification under any debt
instrument or agreement to which either QSRD or the Borrower is now or hereafter
a party.
