         policies of such Person whether by contract or otherwise.

         "Agent" means Union Bank of California, N.A., as Agent hereunder, and
its successors in such capacity; provided, however, that until such time as a
Lender other than Union Bank of California, N.A. becomes a party hereto, "Agent"

                  ARTICLE II - The Loans and Letters of Credit


         Section 2.1. Commitments to Lend; Notes. Subject to the terms and
conditions hereof, each Lender agrees to make loans to Borrower (herein called
such Lender's "Loans") upon Borrower's request from time to time during the
Commitment Period, provided that (a) subject to Sections 3.3, 3.4 and 3.6, all
Lenders are requested to make Loans of the same Type in accordance with their
respective Percentage Shares and as part of the same Borrowing, (b) after giving
effect to such Loans, the Facility Usage does not exceed the Borrowing Base in
effect as of the date on which the requested Loans are to be made, (c) after
giving effect to such Loans, the Facility Usage does not exceed the Senior Debt
Limit in effect as of the date on which the requested Loans are to be made, and
(d) after giving effect to such Loans, the outstanding principal amount of each
Lender's Loans, plus such Lender's Percentage Share of LC Obligations does not
exceed such Lender's Percentage Share of the Borrowing Base in effect as of the
date on which the requested Loans are to be made. The aggregate amount of all
Loans in any Borrowing must be greater than or equal to $2,500,000 or must equal
the remaining availability under the Borrowing Base. Borrower may have no more
than five Borrowings of Eurodollar Loans outstanding at any time. The obligation
of Borrower to repay to each Lender the aggregate amount of all Loans made by
such Lender, together with interest accruing in connection therewith, shall be
evidenced by a single promissory note (herein called such Lender's "Note") made
by Borrower payable to the order of such Lender in the form of Exhibit A with
appropriate insertions. It is expressly understood that Lenders' commitment to
make Loans is determined only by reference to the Borrowing Base from time to
time in effect, and the aggregate face amount of the Notes and the amount
specified in the Security Documents are specified at a greater amount only for
the convenience of the parties to avoid the necessity of preparing and recording
supplements to the Security Documents. The amount of principal owing on any
Lender's Note at any given time shall be the aggregate amount of all Loans
theretofore made by such Lender minus all payments of principal theretofore
received by such Lender on such Note. Interest on each Note shall accrue and be
due and payable as provided herein and therein, with Eurodollar Loans bearing
interest at the Eurodollar Rate and Base Rate Loans bearing interest at the Base
Rate (subject to the applicability of the Default Rate and limited by the
provisions of Section 10.7). On the last day of the Commitment Period, unless
sooner paid as provided herein, all Loans shall be paid in full. Subject to the
terms and conditions hereof, Borrower may borrow, repay, and reborrow hereunder.

         Section 2.2. Requests for New Loans. Borrower must give to Agent
written notice (or telephonic notice promptly confirmed in writing) of any
requested Borrowing of new Loans to be advanced by Lenders. Each such notice
constitutes a "Borrowing Notice" hereunder and must:

                  (a) specify (i) the aggregate amount of any such Borrowing of
         new Base Rate Loans and the date on which such Base Rate Loans are to
         be advanced, or (ii) the aggregate amount of any such Borrowing of new
         Eurodollar Loans, the date on which such Eurodollar Loans are to be
         advanced (which shall be the first day of the Interest Period which is
         to apply thereto), and the length of the applicable Interest Period;
         and

                  (b) be received by Agent not later than 8:00 a.m., Los
         Angeles, California time, on (i) the day on which any such Base Rate
         Loans are to be made, or (ii) the third Business Day preceding the day
         on which any such Eurodollar Loans are to be made.



                                       23
<PAGE>   24

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B, duly completed. Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by Borrower as to the matters which are required to
be set out in such written confirmation. Upon receipt of any such Borrowing
Notice, Agent shall give each Lender prompt notice of the terms thereof. If all
conditions precedent to such new Loans have been met, each Lender will on the
date requested promptly remit to Agent at Agent's office in Los Angeles,
California the amount of such Lender's new Loan in immediately available funds,
and upon receipt of such funds, unless to its actual knowledge any conditions
precedent to such Loans have been neither met nor waived as provided herein,
Agent shall promptly make such Loans available to Borrower. Unless Agent shall
have received prompt notice from a Lender that such Lender will not make
available to Agent such Lender's new Loan, Agent may in its discretion assume
that such Lender has made such Loan available to Agent in accordance with this
section and Agent may if it chooses, in reliance upon such assumption, make such
Loan available to Borrower. If and to the extent such Lender shall not so make
its new Loan available to Agent, such Lender and Borrower severally agree to pay
or repay to Agent within three days after demand the amount of such Loan
together with interest thereon, for each day from the date such amount was made
available to Borrower until the date such amount is paid or repaid to Agent,
with interest at (i) the Federal Funds Rate, if such Lender is making such
payment and (ii) the interest rate applicable at the time to the other new Loans
made on such date, if Borrower is making such repayment. If neither such Lender
nor Borrower pay or repay to Agent such amount within such three-day period,
Agent shall in addition to such amount be entitled to recover from such Lender
and from Borrower, on demand, interest thereon at the Default Rate, calculated
from the date such amount was made available to Borrower. The failure of any
Lender to make any new Loan to be made by it hereunder shall not relieve any
other Lender of its obligation hereunder, if any, to make its new Loan, but no
Lender shall be responsible for the failure of any other Lender to make any new
Loan to be made by such other Lender.

         Section 2.3. Interest Rates; Continuations and Conversions of Existing
Loans.

         (a) Interest Rates. Unless the Default Rate shall be applicable, Base
Rate Loans from time to time outstanding shall bear interest on each day
outstanding at the sum of the Base Rate in effect on such day, but in no event
in excess of the Highest Lawful Rate. Unless the Default Rate shall be
applicable, each Eurodollar Loan shall bear interest on each day during the
related Interest Period at the related Eurodollar Rate in effect on such day,
but in no event in excess of the Highest Lawful Rate. Such interest shall be
payable on the dates specified in the Note. After the occurrence and during the
continuance of an Event of Default and a notice to the Borrower by Agent that
the Default Rate shall apply, all Loans shall bear interest on each day at the
Default Rate in effect on such day, and such interest shall be due and payable
daily as it accrues.

         (b) Continuations and Conversions. Borrower may make the following
elections with respect to Loans already outstanding: to Convert Base Rate Loans
to Eurodollar Loans, to Convert Eurodollar Loans to Base Rate Loans on the last
day of the Interest Period applicable thereto, or to Continue Eurodollar Loans
beyond the expiration of such Interest Period by designating a new Interest
Period to take effect at the time of such expiration. In making such



                                       24
<PAGE>   25

elections, Borrower may combine existing Loans made pursuant to separate
Borrowings into one new Borrowing or divide existing Loans made pursuant to one
Borrowing into separate new Borrowings, provided that Borrower may have no more
than five Borrowings of Eurodollar Loans outstanding at any time. To make any
such election, Borrower must give to Agent written notice (or telephonic notice
promptly confirmed in writing) of any such Conversion or Continuation of
existing Loans, with a separate notice given for each new Borrowing. Each such
notice constitutes a "Continuation/Conversion Notice" hereunder and must:

                  (i) specify the existing Loans which are to be Continued or
         Converted;

                  (ii) specify (A) the aggregate amount of any Borrowing of Base
         Rate Loans into which such existing Loans are to be Continued or
         Converted and the date on which such Continuation or Conversion is to
         occur, or (B) the aggregate amount of any Borrowing of Eurodollar Loans
         into which such existing Loans are to be Continued or Converted, the
         date on which such Continuation or Conversion is to occur (which shall
         be the first day of the Interest Period which is to apply to such
         Eurodollar Loans), and the length of the applicable Interest Period;
         and

                  (iii) be received by Agent not later than 8:00 a.m., Los
         Angeles, California time, on (A) the day on which any such Continuation
         or Conversion to Base Rate Loans is to occur, or (B) the third Business
         Day preceding the day on which any such Continuation or Conversion to
         Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Borrower as to the matters which are
required to be set out in such written confirmation. Upon receipt of any such
Continuation/Conversion Notice, Agent shall give each Lender prompt notice of
the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and
binding on Borrower. During the continuance of any Default, Borrower may not
make any election to Convert existing Loans into Eurodollar Loans or Continue
existing Loans as Eurodollar Loans. If (due to the existence of a Default or for
any other reason) Borrower fails to timely and properly give any notice of
Continuation or Conversion with respect to a Borrowing of existing Eurodollar
Loans at least three days prior to the end of the Interest Period applicable
thereto, such Eurodollar Loans shall automatically be Converted into Base Rate
Loans at the end of such Interest Period. No new funds shall be repaid by
Borrower or advanced by any Lender in connection with any Continuation or
Conversion of existing Loans pursuant to this section, and no such Continuation
or Conversion shall be deemed to be a new advance of funds for any purpose; such
Continuations and Conversions merely constitute a change in the interest rate
applicable to already outstanding Loans.

         Section 2.4. Use of Proceeds. Borrower shall use all Loans to finance
capital expenditures, to refinance existing Indebtedness of Borrower to Agent,
and provide working capital for its operations and for other general business
purposes. Borrower shall use all Letters of Credit for its general corporate
purposes. In no event shall the funds from any Loan or any Letter of Credit be
used directly or indirectly by any Person for personal, family, household or



                                       25
<PAGE>   26

agricultural purposes or for the purpose, whether immediate, incidental or
ultimate, of purchasing, acquiring or carrying any "margin stock" (as such term
is defined in Regulation U and Regulation G promulgated by the Board of
Governors of the Federal Reserve System) or to extend credit to others directly
or indirectly for the purpose of purchasing or carrying any such margin stock.
Borrower represents and warrants that Borrower is not engaged principally, or as
one of Borrower's important activities, in the business of extending credit to
others for the purpose of purchasing or carrying such margin stock.

         Section 2.5. Fees.

         (a) Commitment Fees. In consideration of each Lender's commitment to
make Loans, Borrower will pay to Agent for the account of each Lender a
commitment fee determined on a daily basis at the rate of one-half of one
percent (.50%) per annum times such Lender's Percentage Share of the unused
portion of the Borrowing Base on each day during the Commitment Period,
determined for each such day by deducting the Facility Usage from the amount of
the Borrowing Base at the end of such day. This commitment fee shall be due and
payable in arrears on the last day of each September, December, March, and June,
and at the end of the Commitment Period.

         (b) Agent's Fees. In addition to all other amounts due to Agent under
the Loan Documents, Borrower will pay fees to Agent as described in a letter
agreement of even date herewith between Agent and Borrower.

         Section 2.6. Optional Prepayments. Borrower may, upon three Business
Days' notice to each Lender, from time to time and without premium or penalty
prepay the Notes, in whole or in part, so long as the aggregate amounts of all
partial prepayments of principal on the Notes equals $1,000,000 or any higher
integral multiple of $1,000,000, so long as Borrower does not prepay any
Eurodollar Loan, and so long as Borrower does not make any prepayments which
would reduce the unpaid principal balance of any Loan to less than $100,000
without first either (a) terminating this Agreement or (b) providing assurance
satisfactory to Agent in its discretion that Lenders' legal rights under the
Loan Documents are in no way affected by such reduction. Each prepayment of
principal under this section shall be accompanied by all interest then accrued
and unpaid on the principal so prepaid. Any principal or interest prepaid
pursuant to this section shall be in addition to, and not in lieu of, all
payments otherwise required to be paid under the Loan Documents at the time of
such prepayment.

         Section 2.7. Mandatory Prepayments.

         (a) If at any time the Facility Usage exceeds the Maximum Loan Amount
(whether due to a reduction in the Maximum Loan Amount in accordance with this
Agreement, or otherwise), Borrower shall immediately prepay the principal of the
Loans in an amount at least equal to such excess.

         (b) If at any time the Facility Usage is less than the Maximum Loan
Amount but in excess of the Borrowing Base (such excess being herein called a
"Borrowing Base Deficiency"),



                                       26
<PAGE>   27

Agent shall give notice of such fact to Borrower (herein called a "Deficiency
Notice"), and Borrower shall:

                  (i) within thirty (30) days after the Deficiency Notice give
         notice to Agent electing to prepay the principal of the Loans in a
         single payment, in which event Borrower shall prepay the principal of
         the Loans in an aggregate amount at least equal to such Borrowing Base
         Deficiency (or, if the Loans have been paid in full, pay to LC Issuer
         LC Collateral as required under Section 2.16(a)) on or before the date
         which is sixty (60) days after the Deficiency Notice, or

                  (ii) within 30 days after the Deficiency Notice give notice to
         Agent electing to prepay the principal of the Loans in installments, in
         which event Borrower shall prepay the principal of the Loans in six
         consecutive monthly installments, in an aggregate amount at least equal
         to such Borrowing Base Deficiency (or, if the Loans have been paid in
         full, pay to LC Issuer LC Collateral as required under Section
         2.16(a)), with the first such installment due 30 days after the
         Deficiency Notice, the next five such installments due on the same day
         of each consecutive month, each such installment being in the amount of
         one-sixth of such Borrowing Base Deficiency, or

                  (iii) within 30 days after the Deficiency Notice, certify to
         Agent that Borrower has marketable title, free of any Liens, to oil and
         gas properties not included in such existing Borrowing Base, which
         properties are not subject to any Liens except Permitted Liens, in an
         amount which eliminates such Borrowing Base Deficiency, and provide to
         each Lender the same information regarding such property as would be
         required for an evaluation by Required Lenders under Section 2.9. If
         Required Lenders determine that such properties will not serve to
         eliminate such Borrowing Base Deficiency, then, within five Business
         Days after receiving notice of such determination, Borrower will elect
         to make, and thereafter make, the prepayments specified in either of
         the preceding subsections (i) or (ii) of this subsection (b).

         (c) Each prepayment of principal under this section shall be
accompanied by all interest then accrued and unpaid on the principal so prepaid.
Any principal or interest prepaid pursuant to this section shall be in addition
to, and not in lieu of, all payments otherwise required to be paid under the
Loan Documents at the time of such prepayment.

         Section 2.8. Initial Borrowing Base. During the period from the date
hereof to the first Determination Date, the Borrowing Base shall be $75,000,000.

         Section 2.9. Subsequent Determinations of Borrowing Base. Within 90
days after each Evaluation Date commencing October 1, 2000, Borrower shall
furnish to each Lender all information, reports and data which Agent has then
requested concerning Restricted Persons' businesses and properties (including
their oil and gas properties and interests and the reserves and production
relating thereto), together with the Engineering Report described in Section
6.2. Within forty-five days after receiving such information, reports and data,
or as promptly thereafter as practicable, Required Lenders shall agree upon an
amount for the Borrowing Base (provided that all Lenders must agree to any
increase in the Borrowing Base) and Agent shall by



                                       27
<PAGE>   28

notice to Borrower designate such amount as the new Borrowing Base available to
Borrower hereunder, which designation shall take effect immediately on the date
such notice is sent (herein called a "Determination Date") and shall remain in
effect until but not including the next date as of which the Borrowing Base is
redetermined. If Borrower does not furnish all such information, reports and
data by the date specified in the first sentence of this section, Agent may
nonetheless designate the Borrowing Base at any amount which Required Lenders
determine and may redesignate the Borrowing Base from time to time thereafter
until each Lender receives all such information, reports and data, whereupon
Required Lenders shall designate a new Borrowing Base as described above.
Required Lenders shall determine the amount of the Borrowing Base based (i) upon
the total debt of Restricted Persons and upon the loan value which they in their
discretion assign to the various oil and gas properties of Restricted Persons at
the time in question and (ii) based upon such other credit factors (including
without limitation the assets, liabilities, cash flow, hedged and unhedged
exposure to price, foreign exchange rate, and interest rate changes, business,
properties, prospects, management and ownership of Restricted Persons) as they
in their discretion deem significant. It is expressly understood that Lenders
and Agent have no obligation to agree upon or designate the Borrowing Base at
any particular amount, whether in relation to the Maximum Loan Amount or
otherwise, and that Lenders' commitments to advance funds hereunder is
determined by reference to the Borrowing Base from time to time in effect, which
Borrowing Base shall be used for calculating commitment fees under Section 2.5
and, to the extent permitted by Law and regulatory authorities, for the purposes
of capital adequacy determination and reimbursements under Section 3.2.

         Section 2.10. Borrower's Reduction of the Borrowing Base.

Until the termination of the Commitment Period Borrower may, during the
fifteen-day period beginning on each Determination Date (each such period being
called in this section an "Option Period"), reduce the Borrowing Base from the
amount designated by Agent to any lesser amount. To exercise such option
Borrower must within an Option Period send notice to Agent of the amount of the
Borrowing Base chosen by Borrower. If Borrower does not affirmatively exercise
this option during an Option Period, the Borrowing Base shall be the amount
designated by Agent. Any choice by Borrower of a Borrowing Base shall be
effective as of the first day of the Option Period during which such choice was
made and shall continue in effect until the next date as of which the Borrowing
Base is redetermined.

         Section 2.11. Letters of Credit. Subject to the terms and conditions
hereof, Borrower may during the Commitment Period request LC Issuer to issue one
or more Letters of Credit, provided that, after taking such Letter of Credit
into account:

                  (a) the Facility Usage does not exceed the Borrowing Base at
         such time;

                  (b) the aggregate amount of LC Obligations at such time does
         not exceed $15,000,000;

                  (c) the expiration date of such Letter of Credit is prior to
         the earlier of (i) twelve (12) months after the date of issuance of
         such Letter of Credit or (ii) 30 days before the Maturity Date;



                                       28
<PAGE>   29

                  (d) such Letter of Credit is to be used for general corporate
         purposes of Borrower;

                  (e) such Letter of Credit is not directly or indirectly used
         to assure payment of or otherwise support any Indebtedness of any
         Person, except for Liabilities of any Restricted Person in respect of
         Hedging Contracts permitted pursuant to Section 7.3;

                  (f) the issuance of such Letter of Credit will be in
         compliance with all applicable governmental restrictions, policies, and
         guidelines and will not subject LC Issuer to any cost which is not
         reimbursable under Article III;

                  (g) the form and terms of such Letter of Credit are acceptable
         to LC Issuer in its sole discretion; and

                  (h) all other conditions in this Agreement to the issuance of
         such Letter of Credit have been satisfied.

LC Issuer will honor any such request if the foregoing conditions (a) through
(h) (in the following Section 2.12 called the "LC Conditions") have been met as
of the date of issuance of such Letter of Credit. LC Issuer may choose to honor
any such request for any other Letter of Credit but has no obligation to do so
and may refuse to issue any other requested Letter of Credit for any reason
which LC Issuer in its sole discretion deems relevant.

         Section 2.12. Requesting Letters of Credit. Borrower must make written
application for any Letter of Credit at least five Business Days before the date
on which Borrower desires for LC Issuer to issue such Letter of Credit. By
making any such written application Borrower shall be deemed to have represented
and warranted that the LC Conditions described in Section 2.11 will be met as of
the date of issuance of such Letter of Credit. Each such written application for
a Letter of Credit must be made in writing in the form and substance of Exhibit
E, the terms and provisions of which are hereby incorporated herein by reference
(or in such other form as may mutually be agreed upon by LC Issuer and
Borrower). Two Business Days after the LC Conditions for a Letter of Credit have
been met as described in Section 2.11 (or if LC Issuer otherwise desires to
issue such Letter of Credit), LC Issuer will issue such Letter of Credit at LC
Issuer's office in Los Angeles, California. If any provisions of any LC
Application conflict with any provisions of this Agreement, the provisions of
this Agreement shall govern and control.

         Section 2.13. Reimbursement and Participations.

         (a) Reimbursement by Borrower. Each Matured LC Obligation shall
constitute a loan by LC Issuer to Borrower. Borrower promises to pay to LC
Issuer, or to LC Issuer's order, on demand, the full amount of each Matured LC
Obligation, together with interest thereon at the Base Rate from the date such
matured LC obligation accrues until the third Business Day after demand, and
thereafter at the Default Rate until paid, but in no event in excess of the
Highest Lawful Rate.



                                       29
<PAGE>   30

         (b) Letter of Credit Advances. If the beneficiary of any Letter of
Credit makes a draft or other demand for payment thereunder then Borrower may,
during the interval between the making thereof and the honoring thereof by LC
Issuer, request Lenders to make Loans to Borrower in the amount of such draft or
demand, which Loans shall be made concurrently with LC Issuer's payment of such
draft or demand and shall be immediately used by LC Issuer to repay the amount
of the resulting Matured LC Obligation. Such a request by Borrower shall be made
in compliance with all of the provisions hereof, provided that for the purposes
of the first sentence of Section 2.1 the amount of such Loans shall be
considered but the amount of the Matured LC Obligation to be concurrently paid
by such Loans shall not be considered.

         (c) Participation by Lenders. LC Issuer irrevocably agrees to grant and
hereby grants to each Lender, and -- to induce LC Issuer to issue Letters of
Credit hereunder -- each Lender irrevocably agrees to accept and purchase and
hereby accepts and purchases from LC Issuer, on the terms and conditions
hereinafter stated and for such Lender's own account and risk an undivided
interest equal to such Lender's Percentage Share of LC Issuer's obligations and
rights under each Letter of Credit issued hereunder and the amount of each
Matured LC Obligation paid by LC Issuer thereunder. Each Lender unconditionally
and irrevocably agrees with LC Issuer that, if a Matured LC Obligation is paid
under any Letter of Credit for which LC Issuer is not reimbursed in full by
Borrower in accordance with the terms of this Agreement and the related LC
Application (including any reimbursement by means of concurrent Loans or by the
application of LC Collateral), such Lender shall (in all circumstances and
without set-off or counterclaim) pay to LC Issuer on demand, in immediately
available funds at LC Issuer's address for notices hereunder, such Lender's
Percentage Share of such Matured LC Obligation (or any portion thereof which has
not been reimbursed by Borrower). Each Lender's obligation to pay LC Issuer
pursuant to the terms of this subsection is irrevocable and unconditional. If
any amount required to be paid by any Lender to LC Issuer pursuant to this
subsection is paid by such Lender to LC Issuer within three Business Days after
the date such payment is due, LC Issuer shall in addition to such amount be
entitled to recover from such Lender, on demand, interest thereon calculated
from such due date at the Federal Funds Rate. If any amount required to be paid
by any Lender to LC Issuer pursuant to this subsection is not paid by such
Lender to LC Issuer within three Business Days after the date such payment is
due, LC Issuer shall in addition to such amount be entitled to recover from such
Lender, on demand, interest thereon calculated from such due date at the Default
Rate.

         (d) Distributions to Participants. Whenever LC Issuer has in accordance
with this section received from any Lender payment of such Lender's Percentage
Share of any Matured LC Obligation, if LC Issuer thereafter receives any payment
of such Matured LC Obligation or any payment of interest thereon (whether
directly from Borrower or by application of LC Collateral or otherwise, and
excluding only interest for any period prior to LC Issuer's demand that such
Lender make such payment of its Percentage Share), LC Issuer will distribute to
such Lender its Percentage Share of the amounts so received by LC Issuer;
provided, however, that if any such payment received by LC Issuer must
thereafter be returned by LC Issuer, such Lender shall return to LC Issuer the
portion thereof which LC Issuer has previously distributed to it.



                                       30
<PAGE>   31

         (e) Calculations. A written advice setting forth in reasonable detail
the amounts owing under this section, submitted by LC Issuer to Borrower or any
Lender from time to time, shall be conclusive, absent manifest error, as to the
amounts thereof.

         Section 2.14. Letter of Credit Fees. In consideration of LC Issuer's
issuance of any Letter of Credit, Borrower agrees to pay (a) to Agent, for the
account of all Lenders, a letter of credit fee determined on a daily basis by
applying the Letter of Credit Fee Rate to such Lender's Percentage Share of the
face amount of the Letter of Credit (but in no event less than $500 per annum),
and (b) to such LC Issuer for its own account, a letter of credit fronting fee
at a rate equal to one-eighth percent (.125%) per annum times the face amount of
such Letter of Credit (but in no event less than $250 per annum). The letter of
credit fee and the letter of credit fronting fee will be calculated on the face
amount of each Letter of Credit outstanding on each day at the above-applicable
rates and will be due and payable in arrears on the last day of each March,
June, September and December.

         Section 2.15. No Duty to Inquire.

         (a) Drafts and Demands. LC Issuer is authorized and instructed to
accept and pay drafts and demands for payment under any Letter of Credit without
requiring, and without responsibility for, any determination as to the existence
of any event giving rise to said draft, either at the time of acceptance or
payment or thereafter. LC Issuer is under no duty to determine the proper
identity of anyone presenting such a draft or making such a demand (whether by
tested telex or otherwise) as the officer, representative or agent of any
beneficiary under any Letter of Credit, and payment by LC Issuer to any such
beneficiary when requested by any such purported officer, representative or
agent is hereby authorized and approved. Borrower agrees to hold LC Issuer and
each other Bank Party harmless and indemnified against any liability or claim in
connection with or arising out of the subject matter of this section, WHICH
INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY
OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION
OF ANY KIND BY ANY BANK PARTY, provided only that no Bank Party shall be
entitled to indemnification for that portion, if any, of any liability or claim
which is proximately caused by its own individual gross negligence or willful
misconduct, as determined in a final judgment.

         (b) Extension of Maturity. If the maturity of any Letter of Credit is
extended by its terms or by Law or governmental action, if any extension of the
maturity or time for presentation of drafts or any other modification of the
terms of any Letter of Credit is made at the request of any Restricted Person,
or if the amount of any Letter of Credit is increased at the request of any
Restricted Person, this Agreement shall be binding upon all Restricted Persons
with respect to such Letter of Credit as so extended, increased or otherwise
modified, with respect to drafts and property covered thereby, and with respect
to any action taken by LC Issuer, LC Issuer's correspondents, or any Bank Party
in accordance with such extension, increase or other modification.

         (c) Transferees of Letters of Credit. If any Letter of Credit provides
that it is transferable, LC Issuer shall have no duty to determine the proper
identity of anyone appearing as transferee of such Letter of Credit, nor shall
LC Issuer be charged with responsibility of any



                                       31
<PAGE>   32

nature or character for the validity or correctness of any transfer or
successive transfers, and payment by LC Issuer to any purported transferee or
transferees as determined by LC Issuer is hereby authorized and approved, and
Borrower further agrees to hold LC Issuer and each other Bank Party harmless and
indemnified against any liability or claim in connection with or arising out of
the foregoing, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR
CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY BANK PARTY, provided only that no
Bank Party shall be entitled to indemnification for that portion, if any, of any
liability or claim which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment.

         Section 2.16. LC Collateral.

         (a) LC Obligations in Excess of Borrowing Base. If, after the making of
all mandatory prepayments required under Section 2.7, the principal balance of
the Loans is zero, but the outstanding LC Obligations will exceed the Borrowing
Base, then in addition to such prepayment of the entire principal balance of the
Loans Borrower will immediately pay to LC Issuer an amount equal to such excess.
LC Issuer will hold such amount as security for the remaining LC Obligations
(all such amounts held as security for LC Obligations being herein collectively
called "LC Collateral") until (i) such LC Obligations become Matured LC
Obligations, at which time such LC Collateral may be applied to such Matured LC
Obligations or (ii) such LC Obligations expire at which time any LC Collateral
in excess of any remaining LC Obligations will be returned to Borrower. Neither
this subsection nor the following subsection shall, however, limit or impair any
rights which LC Issuer may have under any other document or agreement relating
to any Letter of Credit, LC Collateral or LC Obligation, including any LC
Application, or any rights which any Bank Party may have to otherwise apply any
payments by Borrower and any LC Collateral under Section 3.1.

         (b) Acceleration of LC Obligations. If the Obligations or any part
thereof become immediately due and payable pursuant to Section 8.1 then, unless
Majority Lenders otherwise specifically elect to the contrary (which election
may thereafter be retracted by Majority Lenders at any time), all LC Obligations
shall become immediately due and payable without regard to whether or not actual
drawings or payments on the Letters of Credit have occurred, and Borrower shall
be obligated to pay to LC Issuer immediately an amount equal to the aggregate LC
Obligations which are then outstanding. All amounts so paid shall first be
applied to Matured LC Obligations and then held by LC Issuer as LC Collateral
until such LC Obligations become Matured LC Obligations, at which time such LC
Collateral shall be applied to such Matured LC Obligations.

         (c) Investment of LC Collateral. Pending application thereof, all LC
Collateral shall be invested by LC Issuer in such investments as LC Issuer may
choose in its sole discretion. All interest on such investments shall be
reinvested or applied to Matured LC Obligations. When all Obligations have been
satisfied in full, including all LC Obligations, all Letters of Credit have
expired or been terminated, and all of Borrower's reimbursement obligations in
connection therewith have been satisfied in full, LC Issuer shall release any
remaining LC Collateral. Borrower hereby assigns and grants to LC Issuer a
continuing security interest in all LC



                                       32
<PAGE>   33

Collateral paid by it to LC Issuer, all investments purchased with such LC
Collateral, and all proceeds thereof to secure its Matured LC Obligations and
its Obligations under this Agreement, each Note, and the other Loan Documents,
and Borrower agrees that such LC Collateral and investments shall be subject to
all of the terms and conditions of the Security Documents. Borrower further
agrees that LC Issuer shall have all of the rights and remedies of a secured
party under the Uniform Commercial Code as adopted in the State of Texas with
respect to such security interest and that an Event of Default under this
Agreement shall constitute a default for purposes of such security interest.

         (d) Payment of LC Collateral. When Borrower is required to provide LC
Collateral for any reason and fails to do so on the day when required, LC Issuer
may without notice to Borrower or any other Restricted Person provide such LC
Collateral (whether by application of proceeds of other Collateral, by transfers
from other accounts maintained with LC Issuer, or otherwise) using any available
funds of Borrower or any other Person also liable to make such payments. Any
such amounts which are required to be provided as LC Collateral and which are
not provided on the date required shall, for purposes of each Security Document,
be considered past due Obligations owing hereunder, and LC Issuer is hereby
authorized to exercise its respective rights under each Security Document to
obtain such amounts.


                        ARTICLE III - Payments to Lenders

         Section 3.1. General Procedures. Borrower will make each payment which
it owes under the Loan Documents to Agent for the account of the Bank Party to
whom such payment is owed. Each such payment must be received by Agent not later
than 10:00 a.m., Los Angeles, California time, on the date such payment becomes
due and payable, in lawful money of the United States of America, without
set-off, deduction or counterclaim, and in immediately available funds. Any
payment received by Agent after such time will be deemed to have been made on
the next following Business Day. Should any such payment become due and payable
on a day other than a Business Day, the maturity of such payment shall be
extended to the next succeeding Business Day, and, in the case of a payment of
principal or past due interest, interest shall accrue and be payable thereon for
the period of such extension as provided in the Loan Document under which such
payment is due. Each payment under a Loan Document shall be due and payable at
the place provided therein and, if no specific place of payment is provided,
shall be due and payable at the place of payment of Agent's Note. When Agent
collects or receives money on account of the Obligations, Agent shall distribute
all money so collected or received, and each Bank Party shall apply all such
money so distributed, as follows:

                  (a) first, for the payment of all Obligations which are then
         due (and if such money is insufficient to pay all such Obligations,
         first to any reimbursements due Agent under Section 6.9 or 10.4 and
         then to the partial payment of all other Obligations then due in
         proportion to the amounts thereof, or as Bank Parties shall otherwise
         agree);

                  (b) then for the prepayment of amounts owing under the Loan
         Documents (other than principal on the Notes) if so specified by
         Borrower;



                                       33
<PAGE>   34

                  (c) then for the prepayment of principal on the Notes,
         together with accrued and unpaid interest on the principal so prepaid;
         and

                  (d) last, for the payment or prepayment of any other
         Obligations.

All payments applied to principal or interest on any Note shall be applied first
to any interest then due and payable, then to principal then due and payable,
and last to any prepayment of principal and interest in compliance with Section
2.6. All distributions of amounts described in any of subsections (b), (c) or
(d) above shall be made by Agent pro rata to each Bank Party then owed
Obligations described in such subsection in proportion to all amounts owed to
all Bank Parties which are described in such subsection; provided that if any
Lender then owes payments to LC Issuer for the purchase of a participation under
Section 2.13(c) or to Agent under Article II or Section 9.4, any amounts
otherwise distributable under this section to such Lender shall be deemed to
belong to LC Issuer or Agent, respectively, to the extent of such unpaid
payments, and Agent shall apply such amounts to make such unpaid payments rather
than distribute such amounts to such Lender.

         Section 3.2. Increased Cost and Reduced Return.

         (a) If, after the date hereof, the adoption of any applicable Law,
rule, or regulation, or any change in any applicable Law, rule, or regulation,
or any change in the interpretation or administration thereof by any
governmental authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or its
Applicable Lending Office) with any request or directive (whether or not having
the force of Law) of any such governmental authority, central bank, or
comparable agency:

                  (i) shall subject such Lender (or its Applicable Lending
         Office) to any tax, duty, or other charge with respect to any
         Eurodollar Loans, its Notes, or its obligation to make Eurodollar
         Loans, or change the basis of taxation of any amounts payable to such
         Lender (or its Applicable Lending Office) under this Agreement or its
         Notes in respect of any Eurodollar Loans (other than taxes imposed on
         the overall net income of such Lender by the jurisdiction in which such
         Lender has its principal office or such Applicable Lending Office);

                  (ii) shall impose, modify, or deem applicable any reserve,
         special deposit, assessment, or similar requirement (other than the
         Reserve Requirement utilized in the determination of the Eurodollar
         Rate) relating to any extensions of credit or other assets of, or any
         deposits with or other liabilities or commitments of, such Lender (or
         its Applicable Lending Office), including the Commitment of such Lender
         hereunder; or

                  (iii) shall impose on such Lender (or its Applicable Lending
         Office) or the London interbank market any other condition affecting
         this Agreement or its Notes or any of such extensions of credit or
         liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, Converting into, Continuing, or
maintaining any Eurodollar Loans or



                                       34
<PAGE>   35

to reduce any sum received or receivable by such Lender (or its Applicable
Lending Office) under this Agreement or its Notes with respect to any Eurodollar
Loans, then Borrower shall pay to such Lender on demand such amount or amounts
as will compensate such Lender for such increased cost or reduction. If any
Lender requests compensation by Borrower under this Section 3.2(a), Borrower
may, by notice to such Lender (with a copy to Agent), suspend the obligation of
such Lender to make or Continue Loans of the Type with respect to which such
compensation is requested, or to Convert Loans of any other Type into Loans of
such Type, until the event or condition giving rise to such request ceases to be
in effect (in which case the provisions of Section 3.5 shall be applicable);
provided that such suspension shall not affect the right of such Lender to
receive the compensation so requested.

         (b) If, after the date hereof, any Lender shall have determined that
the adoption of any applicable law, rule, or regulation regarding capital
adequacy or any change therein or in the interpretation or administration
thereof by any governmental authority, central bank, or comparable agency
charged with the interpretation or administration thereof, or any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such governmental authority, central bank, or comparable agency, has or
would have the effect of reducing the rate of return on the capital of such
Lender or any corporation controlling such Lender as a consequence of such
Lender's obligations hereunder to a level below that which such Lender or such
corporation could have achieved but for such adoption, change, request, or
directive (taking into consideration its policies with respect to capital
adequacy), then from time to time upon demand Borrower shall pay to such Lender
such additional amount or amounts as will compensate such Lender for such
reduction but only to the extent that such Lender has not been compensated
therefor by an increase in the Eurodollar Rate.

         (c) Each Lender shall promptly notify Borrower and Agent of any event
of which it has knowledge, occurring after the date hereof, which will entitle
such Lender to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Lender, be otherwise disadvantageous to it. Any Lender claiming compensation
under this Section shall furnish to Borrower and Agent a statement setting forth
the additional amount or amounts to be paid to it hereunder which shall be
conclusive in the absence of manifest error. In determining such amount, such
Lender shall act in good faith and may use any reasonable averaging and
attribution methods.

         Section 3.3. Limitation on Types of Loans. If on or prior to the first
day of any Interest Period for any Eurodollar Loan:

         (a) Agent determines (which determination shall be conclusive) that by
reason of circumstances affecting the relevant market, adequate and reasonable
means do not exist for ascertaining the Eurodollar Rate for such Interest
Period; or

         (b) the Majority Lenders determine (which determination shall be
conclusive) and notify Agent that the Eurodollar Rate will not adequately and
fairly reflect the cost to Lenders of funding Eurodollar Loans for such Interest
Period;



                                       35
<PAGE>   36

then Agent shall give Borrower prompt notice thereof specifying the relevant
Type of Loans and the relevant amounts or periods, and so long as such condition
remains in effect, Lenders shall be under no obligation to make additional Loans
of such Type, Continue Loans of such Type, or to Convert Loans of any other Type
into Loans of such Type and Borrower shall, on the last day(s) of the then
current Interest Period(s) for the outstanding Loans of the affected Type,
either prepay such Loans or Convert such Loans into another Type of Loan in
accordance with the terms of this Agreement.

         Section 3.4. Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to make, maintain, or fund Eurodollar Loans hereunder,
then such Lender shall promptly notify Borrower thereof and such Lender's
obligation to make or Continue Eurodollar Loans and to Convert other Types of
Loans into Eurodollar Loans shall be suspended until such time as such Lender
may again make, maintain, and fund Eurodollar Loans (in which case the
provisions of Section 3.5 shall be applicable).

         Section 3.5. Treatment of Affected Loans. If the obligation of any
Lender to make a particular Type of Eurodollar Loan or to continue, or to
Convert Loans of any other Type into, Loans of a particular Type shall be
suspended pursuant to Section 3.2 or 3.4 hereof (Loans of such Type being herein
called "Affected Loans" and such Type being herein called the "Affected Type"),
such Lender's Affected Loans shall be automatically Converted into Base Rate
Loans on the last day(s) of the then current Interest Period(s) for Affected
Loans (or, in the case of a Conversion required by Section 3.4 hereof, on such
earlier date as such Lender may specify to Borrower with a copy to Agent) and,
unless and until such Lender gives notice as provided below that the
circumstances specified in Section 3.2 or 3.4 hereof that gave rise to such
Conversion no longer exist:

         (a) to the extent that such Lender's Affected Loans have been so
Converted, all payments and prepayments of principal that would otherwise be
applied to such Lender's Affected Loans shall be applied instead to its Base
Rate Loans; and

         (b) all Loans that would otherwise be made or Continued by such Lender
as Loans of the Affected Type shall be made or Continued instead as Base Rate
Loans, and all Loans of such Lender that would otherwise be Converted into Loans
of the Affected Type shall be Converted instead into (or shall remain as) Base
Rate Loans.

If such Lender gives notice to Borrower (with a copy to Agent) that the
circumstances specified in Section 3.2 or 3.4 hereof that gave rise to the
Conversion of such Lender's Affected Loans pursuant to this Section 3.5 no
longer exist (which such Lender agrees to do promptly upon such circumstances
ceasing to exist) at a time when Loans of the Affected Type made by other
Lenders are outstanding, such Lender's Base Rate Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Loans of the Affected Type, to the extent necessary so that,
after giving effect thereto, all Loans held by Lenders holding Loans of the
Affected Type and by such Lender are held pro rata (as to principal amounts,
Types, and Interest Periods) in accordance with their Percentage Shares of the
Commitment.

         Section 3.6. Compensation. Upon the request of any Lender, Borrower
shall pay to such Lender such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost, or
expense (including loss of anticipated profits) incurred by it as a result of:

         (a) any payment, prepayment, or Conversion of a Eurodollar Loan for any
reason (including, without limitation, the acceleration of the Loans pursuant to
Section 8.1) on a date other than the last day of the Interest Period for such
Loan; or

         (b) any failure by Borrower for any reason (including, without
limitation, the failure of any condition precedent specified in Article IV to be
satisfied) to borrow, Convert, Continue, or prepay a Eurodollar Loan on the date
for such borrowing, Conversion, Continuation, or prepayment specified in the
relevant notice of borrowing, prepayment, Continuation, or Conversion under this
Agreement.

         Section 3.7. Taxes.

         (a) Any and all payments by Borrower to or for the account of any
Lender or Agent hereunder or under any other Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Lender and
Agent, taxes imposed on its income, and franchise taxes imposed on it, by the
jurisdiction under the Laws of which such Lender (or its Applicable Lending
Office) or Agent (as the case may be) is organized or any political subdivision
thereof (all such non-excluded taxes, duties, levies, imposts, deductions,
charges, withholdings, and liabilities being hereinafter referred to as
"Taxes"). If Borrower shall be required by Law to deduct any Taxes from or in
respect of any sum payable under this Agreement or any other Loan Document to
any Lender or Agent, (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 3.7) such Lender or Agent receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) Borrower shall make such deductions, and (iii) Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable Law.

         (b) In addition, Borrower agrees to pay any and all present or future
stamp or documentary taxes and any other excise or property taxes or charges or
similar levies which arise from any payment made under this Agreement or any
other Loan Document or from the execution or delivery of, or otherwise with
respect to, this Agreement or any other Loan Document (hereinafter referred to
as "Other Taxes").

         (c) Borrower agrees to indemnify each Lender and Agent for the full
amount of Taxes and Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section 3.7) paid by such Lender or Agent (as the case may be) and any
liability (including penalties, interest, and expenses) arising therefrom or
with respect thereto.

         (d) Each Lender organized under the Laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Lender listed on the signature pages hereof and on
or prior to the date on which it becomes a Lender in the case of each other
Lender, and from time to time thereafter if requested in writing by Borrower or
Agent (but only so long as such Lender remains lawfully able to do so), shall
provide Borrower and Agent with (i) Internal Revenue Service Form 1001 or 4224,
as appropriate, or any successor form prescribed by the Internal Revenue
Service, certifying that such Lender is entitled to benefits under an income tax
treaty to which the United States is a party which reduces the rate of
withholding tax on payments of interest or certifying that the income receivable
pursuant to this Agreement is effectively connected with the conduct of a trade
or business in the United States, (ii) Internal Revenue Service Form W-8 or W-9,
as appropriate, or any successor form prescribed by the Internal Revenue
Service, and (iii) any other form or certificate required by any taxing
authority (including any certificate required by Sections 871(h) and 881(c) of
the Internal Revenue Code), certifying that such Lender is entitled to an
exemption from or a reduced rate of tax on payments pursuant to this Agreement
or any of the other Loan Documents.

         (e) For any period with respect to which a Lender has failed to provide
Borrower and Agent with the appropriate form pursuant to Section 3.7(d) (unless
such failure is due to a change in treaty, Law, or regulation 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 3.7(a) or
3.7(b) with respect to Taxes imposed by the United States; provided, however,
that should a Lender, which is otherwise exempt from or subject to a reduced
rate of withholding tax, become subject to Taxes because of its failure to
deliver a form required hereunder, Borrower shall take such steps as such Lender
shall reasonably request to assist such Lender to recover such Taxes.

         (f) If Borrower is required to pay additional amounts to or for the
account of any Lender pursuant to this Section 3.7, then such Lender will agree
to use reasonable efforts to change the jurisdiction of its Applicable Lending
Office so as to eliminate or reduce any such additional payment which may
thereafter accrue if such change, in the judgment of such Lender, is not
otherwise disadvantageous to such Lender and in the event Lender is reimbursed
for an amount paid by Borrower pursuant to this Section 3.7, it shall promptly
return such amount to Borrower.

         (g) Within thirty (30) days after the date of any payment of Taxes,
Borrower shall furnish to Agent the original or a certified copy of a receipt
evidencing such payment.

         (h) Without prejudice to the survival of any other agreement of
Borrower hereunder, the agreements and obligations of Borrower contained in this
Section 3.7 shall survive the termination of the Commitment and the payment in
full of the Notes.

         Section 3.8. Compensation Procedure. Any Lender or LC Issuer notifying
Borrower of the incurrence of additional costs under Sections 3.2 through 3.7
shall in such notice to Borrower and Agent set forth in reasonable detail the
basis and amount of its request for compensation.



                                       38

Determinations and allocations by each Lender or LC Issuer for purposes of
Sections 3.2 through 3.7 of the effect of any change in applicable laws,
treaties, rules or regulations or in the interpretation or administration
thereof, any losses or expenses incurred by reason of the liquidation or
reemployment of deposits or other funds, any Taxes imposed, or the effect of
capital maintained on its costs or rate of return of maintaining Loans or its
obligation to make Loans, or on amounts receivable by it in respect of Loans,
and of the amounts required to compensate such Lender under Sections 3.2 through
3.7, shall be conclusive and binding for all purposes, absent manifest error.
Any request for compensation under this Section 3.8 shall be paid by Borrower
within thirty (30) Business Days of the receipt by Borrower of the notice
described in this Section 3.8.

         Section 3.9. Change of Applicable Lending Office. Each Bank Party
agrees that, upon the occurrence of any event giving rise to the operation of
Sections 3.2 through 3.6 with respect to such Bank Party, it will, if requested
by Borrower, use reasonable efforts (subject to overall policy considerations of
such Bank Party) to designate another Lending Office, provided that such
designation is made on such terms that such Bank Party and its Lending Office
suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise to the operation of any such
section. Nothing in this section shall affect or postpone any of the obligations
of Borrower or the rights of any Bank Party provided in Sections 3.2 through
3.6.

         To confirm each Bank Party's understanding concerning Restricted
Persons and Restricted Persons' businesses, properties and obligations and to
induce each Bank Party to enter into this Agreement and to extend credit
hereunder, Parent and Borrower represents and warrants to each Bank Party that:

         Section 5.1. No Default. No Restricted Person is in default in the
performance of any of the covenants and agreements contained in any Loan
Document. No event has occurred and is continuing which constitutes a Default.

         Section 5.2. Organization and Good Standing. Each Restricted Person is
duly organized, validly existing and in good standing under the Laws of its
jurisdiction of organization, having



                                       41
<PAGE>   42

all powers required to carry on its business and enter into and carry out the
transactions contemplated hereby. Each Restricted Person is duly qualified, in
good standing, and authorized to do business in all other jurisdictions within
the United States wherein the character of the properties owned or held by it or
the nature of the business transacted by it makes such qualification necessary.
Each Restricted Person has taken all actions and procedures customarily taken in
order to enter, for the purpose of conducting business or owning property, each
jurisdiction outside the United States wherein the character of the properties
owned or held by it or the nature of the business transacted by it makes such
actions and procedures desirable.

         Section 5.3. Authorization. Each Restricted Person has duly taken all
action necessary to authorize the execution and delivery by it of the Loan
Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder. Borrower is duly authorized to borrow funds hereunder.

         Section 5.4. No Conflicts or Consents. The execution and delivery by
the various Restricted Persons of the Loan Documents to which each is a party,
the performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (i) conflict with any provision of (1) any Law, (2) the
organizational documents of any Restricted Person, or (3) any agreement,
judgment, license, order or permit applicable to or binding upon any Restricted
Person, (ii) result in the acceleration of any Indebtedness owed by any
Restricted Person, (iii) result in or require the creation of any Lien upon any
assets or properties of any Restricted Person, (iv) result in or require the
creation of any guaranty by any Restricted Person of any Indebtedness of any
other Person except for the guaranties listed in the Security Schedule or (v)
violate the restrictions imposed by any of the Indentures. Except as expressly
contemplated in the Loan Documents no consent, approval, authorization or order

connection with the execution, delivery or performance by any Restricted Person
of any Loan Document or to consummate any transactions contemplated by the Loan
Documents.

         Section 5.5. Enforceable Obligations. This Agreement is, and the other
Loan Documents when duly executed and delivered will be, legal, valid and
binding obligations of each Restricted Person which is a party hereto or
thereto, enforceable in accordance with their terms except as such enforcement
may be limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.

         Section 5.6. Initial Financial Statements. Borrower has heretofore
delivered to each Bank Party true, correct and complete copies of the Initial
Financial Statements. The Initial Financial Statements fairly present Parent's
Consolidated financial position at the respective dates thereof and the
Consolidated results of Parent's operations and Parent's Consolidated cash flows
for the respective periods thereof. Since the date of the annual Initial
Financial Statements no Material Adverse Change has occurred, except as
reflected in the Disclosure Schedule. All Initial Financial Statements were
prepared in accordance with GAAP.

         Section 5.7. Other Obligations and Restrictions. No Restricted Person
has any outstanding Liabilities of any kind (including contingent obligations,
tax assessments, and





                                       42
<PAGE>   43

unusual forward or long-term commitments) which are, in the aggregate, material
to such Restricted Person or material with respect to Restricted Persons'
Consolidated financial condition and not shown in the Initial Financial
Statements or disclosed in the Disclosure Schedule or a Disclosure Report.
Except as shown in the Initial Financial Statements or disclosed in the
Disclosure Schedule or a Disclosure Report, no Restricted Person is subject to
or restricted by any franchise, contract, deed, charter restriction, or other
instrument or restriction which could cause a Material Adverse Change.

         Section 5.8. Full Disclosure. No certificate, statement or other
information delivered herewith or heretofore by any Restricted Person to any
Bank Party in connection with the negotiation of this Agreement or in connection
with any transaction contemplated hereby contains any untrue statement of a
material fact or omits to state any material fact known to any Restricted Person
(other than industry-wide risks normally associated with the types of businesses
conducted by Restricted Persons) necessary to make the statements contained
herein or therein not misleading as of the date made or deemed made. There is no
fact known to any Restricted Person (other than industry-wide risks normally
associated with the types of businesses conducted by Restricted Persons) that
has not been disclosed to each Bank Party in writing which could cause a
Material Adverse Change. There are no statements or conclusions in any
Engineering Report which are based upon or include misleading information or
fail to take into account material information regarding the matters reported
therein, it being understood that each Engineering Report is necessarily based
upon professional opinions, estimates and projections and that no Restricted
Person warrants that such opinions, estimates and projections will ultimately
prove to have been accurate. Borrower has heretofore delivered to each Bank
Party true, correct and complete copies of the Initial Engineering Report.

         Section 5.9. Litigation. Except as disclosed in the Initial Financial

legal, equitable, arbitrative or administrative proceedings pending, or to the
knowledge of any Restricted Person threatened, against any Restricted Person
before any Tribunal which could cause a Material Adverse Change, and (ii) there
are no outstanding judgments, injunctions, writs, rulings or orders by any such
Tribunal against any Restricted Person or any Restricted Person's directors or
officers which could cause a Material Adverse Change.

properties of any Restricted Person has been affected by any fire, explosion,
accident, strike, lockout or other labor dispute, drought, storm, hail,

Change.

respects. No ERISA Affiliate is required to contribute to, or has any other
absolute or contingent liability in respect of, any "multiemployer plan" as
defined in Section 4001 of ERISA. Except as set forth in the Disclosure Schedule
or a Disclosure Report: (i) no




                                       43

Revenue Code of 1986, as amended) exists with respect to any ERISA Plan, whether
or not waived by the Secretary of the Treasury or his delegate, and (ii) the
current value of each ERISA Plan's benefits does not exceed the current value of
such ERISA Plan's assets available for the payment of such benefits by more than
$500,000.

locations) of any Hazardous Materials; (c) no Restricted Person (and to the best
knowledge of Borrower, no other Person) has filed any notice under any Law
indicating that any Restricted Person is responsible for the improper release
into the environment, or the improper storage or disposal, of any material
amount of any Hazardous Materials or that any Hazardous Materials have been
improperly released, or are improperly stored or disposed of, upon any property
of any Restricted Person; (d) no Restricted Person has transported or arranged
for the transportation of any Hazardous Material to any location which is (i)
listed on the National Priorities List under the Comprehensive Environmental

Protection Agency in its Comprehensive Environmental Response, Compensation and
Liability Information System List, or listed on any similar state list or (ii)
the subject of federal, state or local enforcement actions or other
investigations which may lead to claims against any Restricted Person for
clean-up costs, remedial work, damages to natural resources or for personal
injury claims (whether under Environmental Laws or otherwise); and (e) no
Restricted Person otherwise has any known material contingent liability under
any Environmental Laws or in connection with the release into the environment,

         Section 5.14. Borrower's Subsidiaries. Parent does not presently have

Schedule or a Disclosure Report and except those associations, joint ventures or
other relationships (a) which are established pursuant to a standard form
operating agreement or similar agreement or which are partnerships for purposes
of federal income taxation only, (b)

its Subsidiaries which is indicated in the Disclosure Schedule.

         Section 5.15. Title to Properties; Licenses. Each Restricted Person has
good and defensible title to all of its material properties and assets, free and
clear of all Liens other than Permitted Liens and of all impediments to the use
of such properties and assets in such Restricted Person's business, except that
no representation or warranty is made with respect to any oil, gas or mineral
property or interest to which no proved oil or gas reserves are properly
attributed. Other than Liens permitted under Section 7.2, each Restricted Person
will respectively own in the aggregate, in all material respects, the net
interests in production attributable to the wells and units evaluated in the
Initial Engineering Reports. The ownership of such Properties shall not in the
aggregate in any material respect obligate such Restricted Person to bear the
costs and expenses relating to the maintenance, development and operations of
such Properties in an amount materially in excess of the working interest of
such Properties set forth in the Initial Engineering Reports. Each Restricted
Person has paid all royalties payable under the oil and gas leases to which it
is operator, except those contested in accordance with the terms of the
applicable joint operating agreement or otherwise contested in good faith by
appropriate proceedings. Upon delivery of each Engineering Report furnished to
the Lenders pursuant to Section 6.2, the statements made in the preceding
sentences of this Section 5.15 shall be true with respect to such Engineering
Reports. All information contained in the Initial Engineering Reports is true
and correct in all material respects as of the date thereof and as of the date
of the first Loan hereunder. Each Restricted Person possesses all licenses,
permits, franchises, patents, copyrights, trademarks and trade names, and other
intellectual property (or otherwise possesses the right to use such intellectual
property without violation of the rights of any other Person) which are
necessary to carry out its business as presently conducted and as presently
proposed to be conducted hereafter, and no Restricted Person is in violation in
any material respect of the terms under which it possesses such intellectual
property or the right to use such intellectual property.

         Section 5.16. Government Regulation. Neither Borrower nor any other
Restricted Person owing Obligations is subject to regulation under the Public
Utility Holding Company Act of 1935, the Federal Power Act, the Investment
Company Act of 1940 (as any of the preceding acts have been amended) or any
other Law which regulates the incurring by such Person of Indebtedness,
including Laws relating to common contract carriers or the sale of electricity,
gas, steam, water or other public utility services.

         Section 5.17. Insider. No Restricted Person, nor any Person having
"control" (as that term is defined in 12 U.S.C. Section 375b(9) or in
regulations promulgated pursuant thereto) of any Restricted Person, is a
"director" or an "executive officer" or "principal shareholder" (as those terms
are defined in 12 U.S.C. Section 375b(8) or (9) or in regulations promulgated
pursuant thereto) of any Bank Party, of a bank holding company of which any Bank
Party is a Subsidiary or of any Subsidiary of a bank holding company of which
any Bank Party is a Subsidiary.

         Section 5.18. Officers, Directors and Shareholders. The officers and
directors of Parent are those persons disclosed in the definitive proxy
statement prepared by Parent and filed with the SEC in connection with Parent's
most recent annual meeting, copies of which proxy statement have been previously
furnished in connection with the negotiation hereof.

         Section 5.19. Solvency. Upon giving effect to the issuance of the
Notes, the execution of the Loan Documents by Borrower and the consummation of
the transactions contemplated hereby, each Restricted Person will be "solvent"
on the date hereof (as such term is used in applicable bankruptcy, liquidation,
receivership, insolvency or similar Laws). Each Restricted Person's capital is
adequate for the businesses in which such Restricted Person is engaged and
intends to be engaged. No Restricted Person has incurred (whether hereby or
otherwise), nor does any Restricted Person intend to incur or believe that it
will incur, debts which will be beyond its ability to pay as such debts mature.

         accepted auditing standards, by Price Waterhouse Coopers or another of
         the five nationally recognized firms of, or other independent certified
         public accountants selected by Borrower and acceptable to Agent,
         stating that such Consolidated financial statements have been so

         calculations showing compliance (or non-compliance) at the end of such
         Fiscal Year with the requirements of Sections 7.11 and 7.12, and (iii)
         further stating that in making their examination and reporting on the
         Consolidated financial statements described above they did not conclude
         that any Default existed at the end of such Fiscal Year or at the time
         of their report, or, if they did conclude that a Default existed,
         specifying its nature and period of existence.

         Year to the end of such Fiscal Quarter, all in reasonable detail and
         prepared in accordance with GAAP, subject to changes resulting from
         normal year-end adjustments. In addition Borrower will, together with
         each such set of financial statements and each set of financial
         statements furnished under subsection (a) of this section, furnish a
         certificate in the form of Exhibit D signed by the chief financial
         officer or treasurer of Parent stating that such financial statements
         are accurate and complete (subject to normal year-end adjustments),

         Fiscal Quarter with the requirements of Sections 7.11 and 7.12 and
         stating that no Default exists at the end of such Fiscal Quarter or at
         the time of such certificate or specifying the nature and period of

         financial statements, reports, notices and proxy statements sent by any
         Restricted Person to its stockholders and all registration statements,

         by independent petroleum engineers chosen by Borrower and acceptable to
         Majority Lenders, concerning all oil and gas properties and interests
         owned by any Restricted Person which are located in or offshore of the
         United States and which have attributable to them proved oil or gas
         reserves. This report shall be satisfactory to Agent, shall contain
         sufficient information to enable Borrower to meet the reporting
         requirements concerning oil and gas reserves contained in Regulations
         S-K and S-X promulgated by the SEC, shall take into account any
         "over-produced" status under gas balancing arrangements, and shall
         contain information and analysis comparable in scope to that contained

         shall deliver a report reflecting, since the date reflected in the most
         recent report delivered pursuant to this clause (d) or pursuant to the
         following clause (e), the following (i) all property sales and pending
         property sales identifying the property and sale price therefor, (ii)
         all property purchases and pending property purchases identifying the
         property and the purchase price therefor, and (iii) additional changes
         in properties in each category from such previous report (i.e.: proven
         undeveloped, proven developed non-producing, or proven producing). This
         report shall




                                       47
<PAGE>   48

         distinguish (or shall be delivered together with a certificate from an
         appropriate officer of Borrower which distinguishes) those properties

         petroleum engineers who are employees of Borrower (or Chesapeake
         Operating Inc. under the management services agreement), together with
         an accompanying report on property sales, property purchases and
         changes in categories, both in the same form and scope as the reports
         in (d) above.

         first year thereof, quarterly financial projections and budgets for
         Restricted Persons, and thereafter yearly financial projections and
         budgets during the Commitment Period.

                  (g) As soon as available, and in any event within sixty (60)
         days after the end of each month, a report describing by lease or unit
         the gross volume of production and sales attributable to production
         during such month from the properties described in subsection (d) above
         and describing the related severance taxes, other taxes, leasehold
         operating expenses and capital costs attributable thereto and incurred
         during such month.

                  (h) As soon as available, and in any event within sixty (60)
         days after the end of each Fiscal Quarter, a report setting forth
         volumes, prices and margins for all marketing activities of Borrower

         Section 6.3. Other Information and Inspections. Each Restricted Person
will furnish to each Bank Party any information which Agent may from time to

<PAGE>   49

                  (a) the occurrence of any Material Adverse Change,

                  (b) the occurrence of any Default,

         to which any of them is a party or by which any of them or any of their
         properties is bound, if such acceleration or default could cause a
         Material Adverse Change,

                  (d) the occurrence of any Termination Event,

                  (e) any claim of $1,000,000 or more, any notice of potential

                  (f) the filing of any suit or proceeding against any
         Restricted Person in which an adverse decision could cause a Material
         Adverse Change.

Upon the occurrence of any of the foregoing Borrower and Guarantors will take
all necessary or appropriate steps to remedy promptly any such Material Adverse
Change, Default, acceleration, default or Termination Event, to protect against
any such adverse claim, to defend any such suit or proceeding, and to resolve
all controversies on account of any of the foregoing. Borrower will also notify
Agent and Agent's counsel in writing at least twenty Business Days prior to the
date that Borrower or any Guarantor changes its name or the location of its
chief executive office or principal place of business or the place where it
keeps its books and records concerning the Collateral, furnishing with such

validity thereof by appropriate proceedings and has set aside on its books
adequate reserves therefor.

         Section 6.8. Insurance. Each Restricted Person will keep or cause to be
kept insured by financially sound and reputable insurers its property in
accordance with the Insurance Schedule. Borrower will maintain the additional
insurance coverage as described in the respective Security Documents. Upon
demand by Agent any insurance policies covering Collateral shall be endorsed (a)
to provide for payment of losses to Agent as its interests may appear, (b) to

         Section 6.15. Perfection and Protection of Security Interests and
Liens. Borrower will from time to time deliver, and will cause each other

the purpose of perfecting, confirming, or protecting any Liens or other rights
in Collateral securing any Obligations.

         Section 6.16. Bank Accounts; Offset. To secure the repayment of the
Obligations Borrower hereby grants to each Bank Party a security interest, a
lien, and a right of offset, each of






                                       52
<PAGE>   53

which shall be in addition to all other interests, liens, and rights of any Bank
Party at common law, under the Loan Documents, or otherwise, and each of which
shall be upon and against (a) any and all moneys, securities or other property

Default, each Bank Party is hereby authorized to foreclose upon, or to offset
against the Obligations then due and payable (in either case without notice to
Borrower), any and all items hereinabove referred to. The remedies of
foreclosure and offset are separate and cumulative, and either may be exercised
independently of the other without regard to procedures or restrictions
applicable to the other.

         Section 6.17. Guaranties of Borrower's Subsidiaries. Each Subsidiary of
Parent other than the Borrower, Chesapeake Marketing, Chesapeake Canada, and
Chesapeake Acquisitions, Ltd., an Alberta corporation (the "Required
Guarantors") now existing or created, acquired or coming into existence after
the date hereof shall, promptly upon request by Agent, execute and deliver to
Agent an absolute and unconditional guaranty of the timely repayment of the
Obligations and the due and punctual performance of the obligations of Borrower
hereunder, which guaranty shall be satisfactory to Agent in form and substance.
Parent will cause each of the Required Guarantors to deliver to Agent,
simultaneously with its delivery of such a guaranty, written evidence
satisfactory to Agent and its counsel that such Required Guarantors has taken

         Section 6.18. Production Proceeds. Notwithstanding that, by the terms
of the various Security Documents, Restricted Persons are and will be assigning
to Agent and Lenders all of the "Production Proceeds" (as defined therein)
accruing to the property covered thereby, so long as no Default has occurred
Restricted Persons may continue to receive from the purchasers of production all
such Production Proceeds, subject, however, to the Liens created under the
Security Documents, which Liens are hereby affirmed and ratified. Upon the
occurrence of a Default, Agent and Lenders may exercise all rights and remedies
granted under the Security Documents, including the right to obtain possession
of all Production Proceeds then held by Restricted Persons or to receive
directly from the purchasers of production all other Production Proceeds. In no
case shall any failure, whether purposed or inadvertent, by Agent or Lenders to
collect directly any such Production Proceeds constitute in any way a waiver,
remission or release of any of their rights under the Security Documents, nor
shall any release of any Production Proceeds by Agent or Lenders to Restricted
Persons constitute a waiver, remission, or release of any other Production
Proceeds or of any rights of Agent or Lenders to collect other Production
Proceeds thereafter.

                  ARTICLE VII - Negative Covenants of Borrower

         To conform with the terms and conditions under which each Bank Party is
willing to have credit outstanding to Borrower, and to induce each Bank Party to
enter into this Agreement and make the Loans, Parent, Borrower and each
Guarantor warrants, covenants and agrees that until the full and final payment
of the Obligations and the termination of this Agreement, unless Majority
Lenders have previously agreed otherwise:

         (a) the Obligations.

         (b) obligations under operating leases entered into in the ordinary
course of such Restricted Person's business in arm's length transactions at

such operating leases do not in the aggregate exceed $500,000.

         (c) unsecured Indebtedness among the Restricted Persons arising in the
ordinary course of business.

         (d) Indebtedness outstanding under the instruments and agreements
described on the Disclosure Schedule, including any renewals or extensions of
such Liabilities which (i) extend the maturity date thereof but not increase the
principal amount thereof, (ii) provide for an interest rate at then prevailing
market rates, and (iii) provide no additional restrictive covenants, negative
covenants, defaults, or events of default than contained in the original of such
documents.

         (e) Indebtedness arising under Hedging Contracts permitted under
Section 7.3.

         (f) Indebtedness of Chesapeake Marketing, in respect of Letters of

time outstanding not to exceed $10,000,000.

         (g) Liabilities with respect to accrued revenues and royalties due to
others during the period the payment thereof has been properly suspended in
accordance with applicable agreements and applicable law.

         Section 7.2. Limitation on Liens. No Restricted Person will create,
assume or permit to exist any Lien upon any of the properties or assets which it
now owns or hereafter acquires, except, to the extent not otherwise forbidden by
the Security Documents the following ("Permitted Liens"):

         (a) Liens which secure Obligations only.

         (b) statutory Liens for taxes, statutory or contractual mechanics' and
materialmen's Liens incurred in the ordinary course of business, and other

                                       54
<PAGE>   55


         (c) as to property which is Collateral, any Liens expressly permitted
to encumber such Collateral under any Security Document covering such
Collateral.

         (d) margins consisting of letters of credit or cash required to be put
up pursuant to any Hedging Contract not to exceed at any time the actual
liquidation liability of the Restricted Person thereon.

         (e) Liens existing on the date hereof and listed on the Disclosure
Schedule.

         (f) Liens on accounts receivable and cash of Chesapeake Marketing
securing Indebtedness permitted by Section 7.1(f).

         Section 7.3. Hedging Contracts. No Restricted Person will be a party to
or in any manner be liable on any Hedging Contract, except:

         (a) Hedging Contracts entered into with the purpose and effect of
fixing prices on oil or gas expected to be produced by Restricted Persons,
provided that at all times: (1) no such contract fixes a price for a term of
more than eighteen (18) months; (2) the aggregate monthly production covered by
all such contracts (determined, in the case of contracts that are not settled on
a monthly basis, by a monthly proration acceptable to Agent) for any single
month does not in the aggregate exceed seventy-five percent (75%) of Restricted
Persons' aggregate Projected Oil and Gas Production anticipated to be sold in
the ordinary course of Restricted Persons' businesses for such month, and (3)
each such contract is with a counterparty or has a guarantor of the obligation
of the counterparty who (unless such counterparty is a Bank Party or one of its
Affiliates) at the time the contract is made has long-term obligations rated AA
or Aa2 or better, respectively, by either Rating Agency or is an investment
grade-rated industry participant. As used in this subsection, the term
"Projected Oil and Gas Production" means the projected production of oil or gas
(measured by volume unit or BTU equivalent, not sales price) for the term of the
contracts or a particular month, as applicable, from properties and interests
owned by any Restricted Person which are located in or offshore of the United
States and which have attributable to them proved oil or gas reserves, as such
production is projected in the most recent report delivered pursuant to Section
6.2(d), after deducting projected production from any properties or interests
sold or under contract for sale that had been included in such report and after
adding projected production from any properties or interests that had not been
reflected in such report but that are reflected in a separate or supplemental
reports meeting the requirements of such Section 6.3(d) above and otherwise are
satisfactory to Agent.

         (b) Hedging Contracts entered into by a Restricted Person with the
purpose and effect of (i) fixing interest rates on a principal amount of
indebtedness of such Restricted Person that is accruing interest at a variable
rate, provided that the aggregate notional amount of such contracts never
exceeds seventy-five percent (75%) of the anticipated outstanding principal
balance of the indebtedness to be hedged by such contracts or an average of such
principal balances calculated using a generally accepted method of matching
interest swap contracts to declining principal balances, and the floating rate
index of each such contract generally matches the index used to determine the
floating rates of interest on the corresponding indebtedness to be hedged by
such





                                       55
<PAGE>   56

contract, or (ii) contracting for variable interest rates on a principal amount
of indebtedness or liquidation preference on preferred stock of such Restricted
Person that is accruing interest or dividends at a fixed rate, provided that the
aggregate notional amount of such contracts never exceeds the amount of the then
liquidation preference on the Parent's 7% Cumulative Convertible Preferred Stock
(to the extent issued prior to the date hereof); and the fixed rate index of
each such contract generally matches the interest on the corresponding
obligation to be hedged by such contract; provided further that in either (i) or
(ii) each such contract is with a counterparty or has a guarantor of the
obligation of the counterparty who (unless such counterparty is a Bank Party or
one of its Affiliates) at the time the contract is made has long-term
obligations rated AA or Aa2 or better, respectively, by either Rating Agency.

         Section 7.4. Limitation on Mergers, Issuances of Securities. Except as
expressly provided in this subsection no Restricted Person will merge or
consolidate with or into any other business entity. Any Subsidiary of Parent
may, however, be merged into or consolidated with (i) another Subsidiary of
Parent (other than Borrower), so long as a Guarantor is the surviving business
entity, (ii) Borrower, so long as Borrower is the surviving business entity, or
(iii) Parent, so long as Parent is the surviving business entity and Borrower
shall not be a party to such merger or consolidation. Parent will not issue any
securities or any option, warrant or other right to acquire shares or other
securities other than (a) shares of its common stock and any options or warrants
giving the holders thereof only the right to acquire such shares and (b) the
Parent's 7% Cumulative Convertible Preferred Stock outstanding on the date of
this Agreement. No Subsidiary of Parent will issue any additional shares of its
capital stock or other securities or any options, warrants or other rights to
acquire such additional shares or other securities except to Parent and only to
the extent not otherwise forbidden under the terms hereof. No Subsidiary of
Borrower which is a partnership will allow any diminution of Borrower's interest
(direct or indirect) therein.

         Section 7.5. Limitation on Sales of Property. No Restricted Person will
sell, transfer, lease, exchange, alienate or dispose of any of its material
assets or properties or any material interest therein except, to the extent not
otherwise forbidden under the Security Documents:

         (a) equipment which is worthless or obsolete or which is replaced by
equipment of equal suitability and value.

         (b) inventory (including oil and gas sold as produced and seismic data)
which is sold in the ordinary course of business on ordinary trade terms.

         (c) interests in oil and gas properties, or portions thereof, to which
no proved reserves of oil, gas or other liquid or gaseous hydrocarbons are
properly attributed.

         (d) other property which is sold for fair consideration to a Person who
is not an Affiliate not to exceed, in the aggregate with respect to all sales of
property after the date of this Agreement, the amount of $100,000,000; provided
that to the extent the aggregate net proceeds of all such sales after the date
of this Agreement exceeds $25,000,000 (i) so long as no Default or Event of
Default shall have occurred and be continuing, the amount of such excess shall
be placed in a segregated account (and, in the case of proceeds of Proved
Developed Properties as





                                       56
<PAGE>   57

that term is defined in the `96 Indenture and the `98 Indenture, subject to a
perfected, first-priority Lien to secure the Obligations) and within four months
following the receipt of such proceeds by the Restricted Person, shall be either
applied to permanently repay outstanding Indebtedness of any Restricted Person
or to pay the purchase price of proved oil and gas properties acquired by a
Restricted Person or to pay development costs with respect to proved oil and gas
properties then owned by a Restricted Person, or (ii) if a Default or Event of
Default shall have occurred and be continuing, the amount of such excess shall
be applied to repay the Obligations and the Borrowing Base shall be reduced by
the amount so applied; provided however no such sale shall include Collateral
unless, in connection with such sale, the Borrowing Base has been redetermined
by Required Lenders pursuant to Section 2.9 giving effect to such transaction
and the Facility Usage will not exceed such Borrowing Base after giving effect
to such transaction. The value of sales under this clause shall be the greater
of the sale price or the discounted present value of the projected future net
revenues (at 10% discount rate) reflected in the most recently delivered
Engineering Report under Section 6.2. Any sale of property, other than as
provided above, shall be subject to the prior written approval of Majority
Lenders, in their sole discretion, which approval may be conditioned upon a
redetermination and reduction of the Borrowing Base after giving effect to such
sale.

No Restricted Person will sell, transfer or otherwise dispose of capital stock
of any of Parent's Subsidiaries. No Restricted Person will discount, sell,
pledge or assign any notes payable to it, accounts receivable or future income
except to the extent expressly permitted under the Loan Documents.

         Section 7.6. Limitation on Dividends and Redemptions. No Restricted
Person will declare or pay any dividends on, or make any other distribution in
respect of, any class of its capital stock or any partnership or other interest
in it, nor will any Restricted Person directly or indirectly make any capital
contribution to or purchase, redeem, acquire or retire any shares of the capital
stock of or partnership interests in any Restricted Person (whether such
interests are now or hereafter issued, outstanding or created), or cause or
permit any reduction or retirement of the capital stock of any Restricted
Person, except as expressly provided in this section. Dividends, distributions,
contributions, purchases, redemptions, acquisitions, retirements or reductions
may be made by any Restricted Person to another Restricted Person. No other
dividends of any type to any Person shall be paid without the prior written
consent of the Agent and Required Lenders.

         Section 7.7. Limitation on Investments and New Businesses. No
Restricted Person will (i) make any expenditure or commitment or incur any
obligation or enter into or engage in any transaction except in the ordinary
course of business, (ii) engage directly or indirectly in any business or
conduct any operations except in connection with or incidental to its present
businesses and operations, (iii) make any acquisitions of or capital
contributions to or other investments in any Person, other than Permitted
Investments, or (iv) make any acquisitions or investments in any properties or
assets (other than a Person) other than: (a) oil and gas properties, (b) gas
gathering, treating and processing assets and assets directly related thereto,
(c) inventory and equipment incidental to its business, (d) general and
administrative assets such as vehicles, offices and office equipment, and (e)
other types of assets not in excess of $500,000 in the aggregate; provided,
however, Restricted Persons may make acquisitions of, capital contributions





                                       57
<PAGE>   58

to, or other investments in any Person or make acquisitions of or investments in
any properties or assets, in each case which are not otherwise permitted by the
foregoing, so long as the aggregate amount thereof made after the date of this
Agreement does not exceed $2,500,000.

         Section 7.8. Limitation on Credit Extensions. Except for Permitted
Investments, no Restricted Person will extend credit, make advances or make
loans other than (i) normal and prudent extensions of credit to customers buying
goods and services in the ordinary course of business, which extensions shall
not be for longer periods than those extended by similar businesses operated in
a normal and prudent manner, (ii) loans to Borrower or to any Guarantor (iii)
extensions of credit to executive officers pursuant to board of directors'
authorizations so long as the aggregate amount of all such loans made by all
Restricted Persons does not exceed the principal amount of such credit extended
as of the date of this Agreement, and (iv) other extensions of credit to
employees of any Restricted Person, so long as the aggregate amount of such
loans to any single employee does not exceed $100,000 and the aggregate amount
of all such loans made by all Restricted Persons does not exceed $500,000.

         Section 7.9. Transactions with Affiliates. No Restricted Person will
engage in any material transaction with any of its Affiliates on terms which are
less favorable to it than those which would have been obtainable at the time in
arm's-length dealing with Persons other than such Affiliates, provided that such
restriction shall not apply to transactions among the Restricted Persons.

         Section 7.10. Certain Contracts; Amendments; Multiemployer ERISA Plans.
Except as expressly provided for in the Loan Documents, no Restricted Person
will, directly or indirectly, enter into, create, or otherwise allow to exist
any contract or other consensual restriction on the ability of any Subsidiary of
Borrower to: (i) pay dividends or make other distributions to Borrower, (ii) to
redeem equity interests held in it by Borrower, (iii) to repay loans and other
indebtedness owing by it to Borrower, or (iv) to transfer any of its assets to
Borrower. No Restricted Person will enter into any "take-or-pay" contract or
other contract or arrangement for the purchase of goods or services which
obligates it to pay for such goods or service regardless of whether they are
delivered or furnished to it. No Restricted Person will amend or permit any
amendment to any contract or lease which releases, qualifies, limits, makes
contingent or otherwise detrimentally affects the rights and benefits of Agent
or any Lender under or acquired pursuant to any Security Documents. No ERISA
Affiliate will incur any obligation to contribute to any "multiemployer plan" as
defined in Section 4001 of ERISA.

         Section 7.11. Current Ratio. The ratio of (i) the sum of Consolidated
current assets of Parent and the other Restricted Persons plus the portion, if
any, of the Borrowing Base which exceeds the Facility Usage to (ii) Consolidated
current liabilities of Parent and the other Restricted Persons will never be
less than 1.0 to 1.0. For purposes of this section, all LC Obligations shall be
included as current liabilities, regardless of whether or not contingent (but
without duplication) and current liabilities shall exclude current maturities of
long term debt and current maturities of the Loans.



                                       58

Consolidated EBITDA for any Fiscal Quarter to (b) Consolidated Fixed Charges for
such Fiscal Quarter shall never be less than 2.0 to 1.0.


                  ARTICLE VIII - Events of Default and Remedies


         Section 8.1. Events of Default. Each of the following events
constitutes an Event of Default under this Agreement:

         (a) Borrower or any Guarantor fails to pay the principal component of
any Obligation when due and payable, whether at a date for the payment of a
fixed installment or as a contingent or other payment becomes due and payable or
as a result of acceleration or otherwise;

         (b) Borrower or any Guarantor fails to pay any Obligation (other than
the Obligations in subsection (a) above) when due and payable, whether at a date

becomes due and payable or as a result of acceleration or otherwise, within
three Business Days after the same becomes due;

         (c) Any "default" or "event of default" occurs under any Loan Document
which defines either such term, and the same is not remedied within the

with any covenant, agreement or provision of Section 6.4 or Article VII;

         (e) Borrower or any Guarantor fails (other than as referred to in
subsections (a), (b), (c) or (d) above) to duly observe, perform or comply with
any covenant, agreement, condition or provision of any Loan Document, and such
failure remains unremedied for a period of thirty (30) days after notice of such
failure is given by Agent to Borrower;

         (f) Any representation or warranty previously, presently or hereafter
made in writing by or on behalf of any Restricted Person in connection with any
Loan Document shall prove to have been false or incorrect in any material
respect on any date on or as of which made, or any Loan Document at any time
ceases to be valid, binding and enforceable as warranted in Section 5.5 for any
reason other than its release or subordination by Agent;

         (g) Any Restricted Person fails to duly observe, perform or comply with
any agreement with any Person or any term or condition of any instrument, if
such agreement or instrument is materially significant to Parent or to Parent
and its Subsidiaries on a Consolidated basis or materially significant to any
Guarantor, and such failure is not remedied within the applicable period of
grace (if any) provided in such agreement or instrument;

         (h) Any Restricted Person (i) fails to pay any portion, when such
portion is due, of any of its Indebtedness in excess of $1,000,000, or (ii)

any such Indebtedness is issued, evidenced, governed, or




                                       59
<PAGE>   60

secured, and any such failure, breach or default continues beyond any applicable
period of grace provided therefor;

$100,000 exists with respect to any ERISA Plan, whether or not waived by the
Secretary of the Treasury or his delegate, or (ii) any Termination Event occurs
with respect to any ERISA Plan and the then current value of such ERISA Plan's
benefit liabilities exceeds the then current value of such ERISA Plan's assets
available for the payment of such benefit liabilities by more than $100,000 (or
in the case of a Termination Event involving the withdrawal of a substantial
employer, the withdrawing employer's proportionate share of such excess exceeds
such amount); and

         (j) Any Restricted Person:

                  (i) suffers the entry against it of a judgment, decree or
         order for relief by a Tribunal of competent jurisdiction in an
         involuntary proceeding commenced under any applicable bankruptcy,
         insolvency or other similar Law of any jurisdiction now or hereafter in
         effect, including the federal Bankruptcy Code, as from time to time

         receiver, liquidator, assignee, custodian, trustee, sequestrator or
         similar official of all or a substantial part of its assets or of any
         part of the Collateral in a proceeding brought against or initiated by
         it, and such appointment or taking possession is neither made
         ineffective nor discharged within thirty days after the making thereof,
         or such appointment or taking possession is at any time consented to,
         requested by, or acquiesced to by it; or

                  (iv) suffers the entry against it of a final judgment for the
         payment of money in excess of $1,000,000 (not covered by insurance
         satisfactory to Majority Lenders in their discretion), unless the same
         is discharged within thirty days after the date of entry thereof or an

         released within thirty days after the entry or levy thereof or after
         any stay is vacated or set aside; and

         (k) Any Change in Control occurs; and

         (l) Any Material Adverse Change occurs.

Upon the occurrence of an Event of Default described in subsection (j)(i),
(j)(ii) or (j)(iii) of this section with respect to Borrower, all of the
Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Guarantor who at any time ratifies
or approves this Agreement. Upon any such acceleration, any obligation of any
Lender to make any further Loans and any obligation of LC Issuer to issue
Letters of Credit hereunder shall be permanently terminated. During the
continuance of any other Event of Default, Agent at any time and from time to
time may (and upon written instructions from Majority Lenders, Agent shall),
without notice to Borrower or any Guarantor, do either or both of the following:
(1) terminate any obligation of Lenders to make Loans hereunder and any
obligation of LC Issuer to issue Letters of Credit hereunder, and (2) declare
any or all of the Obligations immediately due and payable, and all such
Obligations shall thereupon be immediately due and payable, without demand,

acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Guarantor who at any time ratifies
or approves this Agreement.

         Section 8.2. Remedies. If any Default shall occur and be continuing,
each Bank Party may protect and enforce its rights under the Loan Documents by
any appropriate proceedings, including proceedings for specific performance of
any covenant or agreement contained in any Loan Document, and each Bank Party
may enforce the payment of any Obligations due it or enforce any other legal or
equitable right which it may have. All rights, remedies and powers conferred
upon Bank Parties under the Loan Documents shall be deemed cumulative and not
exclusive of any other rights, remedies or powers available under the Loan
Documents or at Law or in equity.

                               ARTICLE IX - Agent

         Section 9.1. Appointment and Authority. Each Bank Party hereby
irrevocably authorizes Agent, and Agent hereby undertakes, to receive payments
of principal, interest and other amounts due hereunder as specified herein and
to take all other actions and to exercise such powers under the Loan Documents
as are specifically delegated to Agent by the terms hereof or thereof, together
with all other powers reasonably incidental thereto. The relationship of Agent
to the other Bank Parties is only that of one commercial lender acting as
administrative agent for others, and nothing in the Loan Documents shall be
construed to constitute Agent a trustee or other fiduciary for any holder of any
of the Notes or of any participation therein nor to impose on Agent duties and
obligations other than those expressly provided for in the Loan Documents.






                                       61
<PAGE>   62

With respect to any matters not expressly provided for in the Loan Documents and
any matters which the Loan Documents place within the discretion of Agent, Agent
shall not be required to exercise any discretion or take any action, and it may
request instructions from Lenders with respect to any such matter, in which case
it shall be required to act or to refrain from acting (and shall be fully
protected and free from liability to all Lenders in so acting or refraining from
acting) upon the instructions of Majority Lenders (including itself), provided,
however, that Agent shall not be required to take any action which exposes it to
a risk of personal liability that it considers unreasonable or which is contrary
to the Loan Documents or to applicable Law. Upon receipt by Agent from Borrower
of any communication calling for action on the part of Lenders or upon notice
from any other Bank Party to Agent of any Default or Event of Default, Agent
shall promptly notify each other Bank Party thereof.

         Section 9.2. Exculpation, Agent's Reliance, Etc. Neither Agent nor any
of its directors, officers, agents, attorneys, or employees shall be liable for
any action taken or omitted to be taken by any of them under or in connection
with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that
each shall be liable for its own gross negligence or willful misconduct. Without
limiting the generality of the foregoing, Agent (a) may treat the payee of any
Note as the holder thereof until Agent receives written notice of the assignment
or transfer thereof in accordance with this Agreement, signed by such payee and
in form satisfactory to Agent; (b) may consult with legal counsel (including
counsel for Borrower), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts; (c) makes no warranty or representation to any other Bank Party and
shall not be responsible to any other Bank Party for any statements, warranties
or representations made in or in connection with the Loan Documents; (d) shall
not have any duty to ascertain or to inquire as to the performance or observance
of any of the terms, covenants or conditions of the Loan Documents on the part
of any Restricted Person or to inspect the property (including the books and
records) of any Restricted Person; (e) shall not be responsible to any other
Bank Party for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of any Loan Document or any instrument or
document furnished in connection therewith; (f) may rely upon the
representations and warranties of each Restricted Person and the Lenders in
exercising its powers hereunder; and (g) shall incur no liability under or in
respect of the Loan Documents by acting upon any notice, consent, certificate or
other instrument or writing (including any facsimile, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper Person or Persons.

         Section 9.3. Credit Decisions. Each Bank Party acknowledges that it
has, independently and without reliance upon any other Bank Party, made its own
analysis of Borrower and the transactions contemplated hereby and its own
independent decision to enter into this Agreement and the other Loan Documents.
Each Bank Party also acknowledges that it will, independently and without
reliance upon any other Bank Party and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under the Loan Documents.

         Section 9.4. Indemnification. Each Lender agrees to indemnify Agent (to
the extent not reimbursed by Borrower within ten (10) days after demand) from
and against such Lender's






                                       62
<PAGE>   63

Percentage Share of any and all liabilities, obligations, claims, losses,
damages, penalties, fines, actions, judgments, suits, settlements, costs,
expenses or disbursements (including reasonable fees of attorneys, accountants,
experts and advisors) of any kind or nature whatsoever (in this section
collectively called "liabilities and costs") which to any extent (in whole or in
part) may be imposed on, incurred by, or asserted against Agent growing out of,
resulting from or in any other way associated with any of the Collateral, the
Loan Documents and the transactions and events (including the enforcement
thereof) at any time associated therewith or contemplated therein (whether
arising in contract or in tort or otherwise and including any violation or
noncompliance with any Environmental Laws by any Person or any liabilities or
duties of any Person with respect to Hazardous Materials found in or released
into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,

provided only that no Lender shall be obligated under this section to indemnify
Agent for that portion, if any, of any liabilities and costs which is
proximately caused by Agent's own individual gross negligence or willful
misconduct, as determined in a final judgment. Cumulative of the foregoing, each
Lender agrees to reimburse Agent promptly upon demand for such Lender's
Percentage Share of any costs and expenses to be paid to Agent by Borrower under
Section 10.4(a) to the extent that Agent is not timely reimbursed for such
expenses by Borrower as provided in such section. As used in this section the
term "Agent" shall refer not only to the Person designated as such in Section
1.1 but also to each director, officer, agent, attorney, employee,
representative and Affiliate of such Person.

         Section 9.5. Rights as Lender. In its capacity as a Lender, Agent shall
have the same rights and obligations as any Lender and may exercise such rights
as though it were not Agent. Agent may accept deposits from, lend money to, act
as Trustee under indentures of, and generally engage in any kind of business
with any Restricted Person or their Affiliates, all as if it were not Agent
hereunder and without any duty to account therefor to any other Lender.

         Section 9.6. Sharing of Set-Offs and Other Payments. Each Bank Party
agrees that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against Borrower
or otherwise, obtain payment of a portion of the aggregate Obligations owed to
it which, taking into account all distributions made by Agent under Section 3.1,
causes such Bank Party to have received more than it would have received had
such payment been received by Agent and distributed pursuant to Section 3.1,
then (a) it shall be deemed to have simultaneously purchased and shall be
obligated to purchase interests in the Obligations as necessary to cause all
Bank Parties to share all payments as provided for in Section 3.1, and (b) such
other adjustments shall be made from time to time as shall be equitable to
ensure that Agent and all Lenders share all payments of Obligations as provided
in Section 3.1; provided, however, that nothing herein contained shall in any
way affect the right of any Bank Party to obtain payment (whether by exercise of
rights of banker's lien, set-off or counterclaim or otherwise) of indebtedness
other than the Obligations. Borrower expressly consents to the foregoing
arrangements and agrees that any holder of any such interest or other




                                       63
<PAGE>   64

participation in the Obligations, whether or not acquired pursuant to the
foregoing arrangements, may to the fullest extent permitted by Law exercise any
and all rights of banker's lien, set-off, or counterclaim as fully as if such
holder were a holder of the Obligations in the amount of such interest or other
participation. If all or any part of any funds transferred pursuant to this
section is thereafter recovered from the seller under this section which
received the same, the purchase provided for in this section shall be deemed to
have been rescinded to the extent of such recovery, together with interest, if
any, if interest is required pursuant to the order of a Tribunal to be paid on
account of the possession of such funds prior to such recovery.

         Section 9.7. Investments. Whenever Agent in good faith determines that
it is uncertain about how to distribute to Lenders any funds which it has
received, or whenever Agent in good faith determines that there is any dispute
among Lenders about how such funds should be distributed, Agent may choose to
defer distribution of the funds which are the subject of such uncertainty or
dispute. If Agent in good faith believes that the uncertainty or dispute will
not be promptly resolved, or if Agent is otherwise required to invest funds
pending distribution to Lenders, Agent shall invest such funds pending
distribution; all interest on any such investment shall be distributed upon the
distribution of such investment and in the same proportion and to the same
Persons as such investment. All moneys received by Agent for distribution to
Lenders (other than to the Person who is Agent in its separate capacity as a
Lender) shall be held by Agent pending such distribution solely as Agent for
such Lenders, and Agent shall have no equitable title to any portion thereof.

         Section 9.8. Benefit of Article IX. The provisions of this Article
(other than the following Section 9.9) are intended solely for the benefit of
Bank Parties, and no Restricted Person shall be entitled to rely on any such
provision or assert any such provision in a claim or defense against any Bank
Party. Bank Parties may waive or amend such provisions as they desire without
any notice to or consent of Borrower or any Restricted Person.

         Section 9.9. Resignation. Agent may resign at any time by giving
written notice thereof to Lenders and Borrower. Each such notice shall set forth
the date of such resignation. Upon any such resignation, Majority Lenders shall
have the right to appoint a successor Agent. A successor must be appointed for
any retiring Agent, and such Agent's resignation shall become effective when
such successor accepts such appointment. If, within thirty days after the date
of the retiring Agent's resignation, no successor Agent has been appointed and
has accepted such appointment, then the retiring Agent may appoint a successor
Agent, which shall be a commercial bank organized or licensed to conduct a
banking or trust business under the Laws of the United States of America or of
any state thereof. Upon the acceptance of any appointment as Agent hereunder by
a successor Agent, the retiring Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents. After any
retiring Agent's resignation hereunder the provisions of this Article IX shall
continue to inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent under the Loan Documents.

                            ARTICLE X - Miscellaneous

         Section 10.1. Waivers and Amendments; Acknowledgments.

         (a) Waivers and Amendments. No failure or delay (whether by course of
conduct or otherwise) by any Bank Party in exercising any right, power or remedy
which such Bank Party may have under any of the Loan Documents shall operate as
a waiver thereof or of any other right, power or remedy, nor shall any single or
partial exercise by any Bank Party of any such right, power or remedy preclude
any other or further exercise thereof or of any other right, power or remedy. No
waiver of any provision of any Loan Document and no consent to any departure
therefrom shall ever be effective unless it is in writing and signed as provided
below in this section, and then such waiver or consent shall be effective only
in the specific instances and for the purposes for which given and to the extent
specified in such writing. No notice to or demand on Borrower or any Guarantor
shall in any case of itself entitle Borrower or any Guarantor to any other or
further notice or demand in similar or other circumstances. This Agreement and
the other Loan Documents set forth the entire understanding between the parties
hereto with respect to the transactions contemplated herein and therein and
supersede all prior discussions and understandings with respect to the subject
matter hereof and thereof, and no waiver, consent, release, modification or
amendment of or supplement to this Agreement or the other Loan Documents shall
be valid or effective against any party hereto unless the same is in writing and
signed by (i) if such party is Borrower, by Borrower, (ii) if such party is
Agent or LC Issuer, by such party, and (iii) if such party is a Lender, by such
Lender or by Agent on behalf of Lenders with the written consent of Majority
Lenders (which consent has already been given as to the termination of the Loan
Documents as provided in Section 10.9). Notwithstanding the foregoing or
anything to the contrary herein, Agent shall not, without the prior consent of
each individual Lender, execute and deliver on behalf of such Lender any waiver
or amendment which would: (1) waive any of the conditions specified in Article
IV (provided that Agent may in its discretion withdraw any request it has made
under Section 4.2(e)), (2) increase the Borrowing Base above the Maximum Loan
Amount which requires the agreement of all Lenders pursuant to Section 2.9, (3)
increase the Maximum Loan Amount of such Lender or subject such Lender to any
additional obligations, (4) reduce any fees payable to such Lender hereunder, or
the principal of, or interest on, such Lender's Note, (5) postpone any date
fixed for any payment of any such fees, principal or interest, (6) amend the
definition herein of "Majority Lenders" or otherwise change the aggregate amount
of Percentage Shares which is required for Agent, Lenders or any of them to take
any particular action under the Loan Documents, or (7) release Borrower from its
obligation to pay such Lender's Note or any Guarantor from its guaranty of such
payment.

         (b) Acknowledgments and Admissions. Borrower hereby represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and
the other Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by Agent or any Lender,
whether written, oral or implicit, other than as expressly set out in this
Agreement or in another Loan Document delivered on or after the date hereof,
(iii) there are no representations, warranties, covenants, undertakings or
agreements by any Bank Party as to the Loan Documents except as expressly set
out in this Agreement or in another Loan Document delivered on or after the date
hereof, (iv) no Bank Party has any fiduciary obligation toward Borrower with
respect to any Loan Document or the transactions contemplated thereby, (v) the
relationship pursuant to the Loan Documents between Borrower and the Guarantors,
on one hand, and each Bank Party, on the





                                       65
<PAGE>   66

other hand, is and shall be solely that of debtor and creditor, respectively,
(vi) no partnership or joint venture exists with respect to the Loan Documents
between any Restricted Person and any Bank Party, (vii) Agent is not Borrower's
Agent, but Agent for Lenders, (viii) should an Event of Default or Default occur
or exist, each Bank Party will determine in its sole discretion and for its own
reasons what remedies and actions it will or will not exercise or take at that
time, (ix) without limiting any of the foregoing, Borrower is not relying upon
any representation or covenant by any Bank Party, or any representative thereof,
and no such representation or covenant has been made, that any Bank Party will,
at the time of an Event of Default or Default, or at any other time, waive,
negotiate, discuss, or take or refrain from taking any action permitted under
the Loan Documents with respect to any such Event of Default or Default or any
other provision of the Loan Documents, and (x) all Bank Parties have relied upon
the truthfulness of the acknowledgments in this section in deciding to execute
and deliver this Agreement and to become obligated hereunder.

         (c) Representation by Lenders. Each Lender hereby represents that it
will acquire its Note for its own account in the ordinary course of its
commercial lending business; however, the disposition of such Lender's property
shall at all times be and remain within its control and, in particular and
without limitation, such Lender may sell or otherwise transfer its Note, any
participation interest or other interest in its Note, or any of its other rights
and obligations under the Loan Documents, subject, however, to the provisions of
Section 10.5.

         (d) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

           THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         Section 10.2. Survival of Agreements; Cumulative Nature. All of
Restricted Persons' various representations, warranties, covenants and
agreements in the Loan Documents shall survive the execution and delivery of
this Agreement and the other Loan Documents and the performance hereof and
thereof, including the making or granting of the Loans and the delivery of the
Notes and the other Loan Documents, and shall further survive until all of the
Obligations are paid in full to each Bank Party and all of Bank Parties'
obligations to Borrower are terminated. All statements and agreements contained
in any certificate or other instrument delivered by Borrower or any Guarantor to
any Bank Party under any Loan Document shall be deemed representations and
warranties by Borrower or agreements and covenants of Borrower under this
Agreement. The representations, warranties, indemnities, and covenants made by
Restricted Persons in the Loan Documents, and the rights, powers, and privileges
granted to Bank Parties in the Loan Documents, are cumulative, and, except for
expressly specified waivers and consents, no Loan Document shall be construed in
the context of another to diminish, nullify, or otherwise reduce the benefit to
any Bank Party of any such representation, warranty, indemnity, covenant, right,
power or privilege. In particular and without limitation, no exception set out
in this Agreement to any representation, warranty, indemnity, or covenant herein
contained shall apply to any similar representation, warranty, indemnity, or
covenant contained in any other Loan Document, and each such similar
representation, warranty, indemnity, or





                                       66
<PAGE>   67

covenant shall be subject only to those exceptions which are expressly made
applicable to it by the terms of the various Loan Documents.

         Section 10.3. Notices. All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Agent may give telephonic notices to the other Bank Parties), and shall be
deemed sufficiently given or furnished if delivered by personal delivery, by
facsimile or other electronic transmission, by delivery service with proof of
delivery, or by registered or certified United States mail, postage prepaid, to
Borrower and Restricted Persons at the address of Borrower specified on the
signature pages hereto and to each Bank Party at its address specified on the
signature pages hereto (unless changed by similar notice in writing given by the
particular Person whose address is to be changed). Any such notice or
communication shall be deemed to have been given (a) in the case of personal
delivery or delivery service, as of the date of first attempted delivery during
normal business hours at the address provided herein, (b) in the case of
facsimile or other electronic transmission, upon receipt, or (c) in the case of
registered or certified United States mail, three days after deposit in the
mail; provided, however, that no Borrowing Notice shall become effective until
actually received by Agent.

         Section 10.4. Payment of Expenses; Indemnity.

         (a) Payment of Expenses. Whether or not the transactions contemplated
by this Agreement are consummated, Borrower will promptly (and in any event,
within 30 days after any invoice or other statement or notice) pay: (i) all
transfer, stamp, mortgage, documentary or other similar taxes, assessments or
charges levied by any governmental or revenue authority in respect of this
Agreement or any of the other Loan Documents or any other document referred to
herein or therein, (ii) all reasonable costs and expenses incurred by or on
behalf of Agent (including, without limitation, attorneys' fees, consultants'
fees and engineering fees, travel costs and miscellaneous expenses) in
connection with (1) the negotiation, preparation, execution and delivery of the
Loan Documents, and any and all consents, waivers or other documents or
instruments relating thereto, (2) the filing, recording, refiling and
re-recording of any Loan Documents and any other documents or instruments or
further assurances required to be filed or recorded or refiled or re-recorded by
the terms of any Loan Document, (3) the borrowings hereunder and other action
reasonably required in the course of administration hereof, (4) monitoring or
confirming (or preparation or negotiation of any document related to) Borrower's
compliance with any covenants or conditions contained in this Agreement or in
any Loan Document, and (iii) all reasonable costs and expenses incurred by or on
behalf of any Bank Party (including, without limitation, attorneys' fees,
consultants' fees and accounting fees) in connection with the defense or
enforcement of any of the Loan Documents (including this section) or the defense
of any Bank Party's exercise of its rights thereunder. In addition to the
foregoing, until and all Obligations have been paid in full, Borrower will also
pay or reimburse Agent for all reasonable out-of-pocket costs and expenses of
Agent or its agents or employees in connection with the continuing
administration of the Loans and the related due diligence of Agent, including
travel and miscellaneous expenses and fees and expenses of Agent's outside
counsel, reserve engineers and consultants engaged in connection with the Loan
Documents.

         (b) Indemnity. Borrower agrees to indemnify each Bank Party, upon
demand, from and against any and all liabilities, obligations, claims, losses,
damages, penalties, fines, actions, judgments, suits, settlements, costs,
expenses or disbursements (including reasonable fees of attorneys, accountants,
experts and advisors) of any kind or nature whatsoever (in this section
collectively called "liabilities and costs") which to any extent (in whole or in
part) may be imposed on, incurred by, or asserted against such Bank Party
growing out of, resulting from or in any other way associated with any of the
Collateral, the Loan Documents and the transactions and events (including the
enforcement or defense thereof) at any time associated therewith or contemplated
therein (whether arising in contract or in tort or otherwise and including any
violation or noncompliance with any Environmental Laws by any Restricted Person
or any liabilities or duties of any Restricted Person or any Bank Party with
respect to Hazardous Materials found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY BANK PARTY,

provided only that no Bank Party shall be entitled under this section to receive
indemnification for that portion, if any, of any liabilities and costs which is
proximately caused by its own individual gross negligence or willful misconduct,
as determined in a final judgment. If any Person (including Borrower or any of
its Affiliates) ever alleges such gross negligence or willful misconduct by any
Bank Party, the indemnification provided for in this section shall nonetheless
be paid upon demand, subject to later adjustment or reimbursement, until such
time as a court of competent jurisdiction enters a final judgment as to the
extent and effect of the alleged gross negligence or willful misconduct. As used
in this section the term "Bank Parties" shall refer not only to the Persons
designated as such in Section 1.1 but also to each director, officer, agent,
attorney, employee, representative and Affiliate of such Persons.

         Section 10.5. Joint and Several Liability; Parties in Interest;
Assignments. All Obligations which are incurred by Borrower and/or two or more
Guarantors shall be their joint and several obligations and liabilities. All
grants, covenants and agreements contained in the Loan Documents shall bind and
inure to the benefit of the parties thereto and their respective successors and
assigns; provided, however, that no Borrower or Guarantor may assign or transfer
any of its rights or delegate any of its duties or obligations under any Loan
Document without the prior consent of all of the Lenders. Neither Borrower nor
any Affiliates of Borrower shall directly or indirectly purchase or otherwise
retire any Obligations owed to any Lender nor will any Lender accept any offer
to do so, unless each Lender shall have received substantially the same offer
with respect to the same Percentage Share of the Obligations owed to it. If
Borrower or any Affiliate of Borrower at any time purchases some but less than
all of the Obligations owed to all Bank Parties, such purchaser shall not be
entitled to any rights of any Bank Party under the Loan Documents unless and
until Borrower or its Affiliates have purchased all of the Obligations.

         (b) No Lender shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person only if the agreement





                                       68
<PAGE>   69

between such Lender and such participant at all times provides: (i) that such
participation exists only as a result of the agreement between such participant
and such Lender and that such transfer does not give such participant any right
to vote as a Lender or any other direct claims or rights against any Person
other than such Lender, (ii) that such participant is not entitled to payment
from any Borrower or Guarantor under Sections 3.2 through 3.7 of amounts in
excess of those payable to such Lender under such sections (determined without
regard to the sale of such participation), and (iii) unless such participant is
an Affiliate of such Lender, that such participant shall not be entitled to
require such Lender to take any action under any Loan Document or to obtain the
consent of such participant prior to taking any action under any Loan Document,
except for actions which would require the consent of all Lenders under the
next-to-last sentence of subsection (a) of Section 10.1. No Lender selling such
a participation shall, as between the other parties hereto and such Lender, be
relieved of any of its obligations hereunder as a result of the sale of such
participation. Each Lender which sells any such participation to any Person
(other than an Affiliate of such Lender) shall give prompt notice thereof to
Agent and Borrower.

         (c) Except for sales of participations under the immediately preceding
subsection (b), no Lender shall make any assignment or transfer of any kind of
its commitments or any of its rights under its Loans or under the Loan
Documents, except for assignments to an Eligible Transferee, and then only if
such assignment is made in accordance with the following requirements:

                  (i) Each such assignment shall apply to all Obligations owing
         to the assignor Lender hereunder and to the unused portion of the
         assignor Lender's commitments, so that after such assignment is made
         the assignor Lender shall have a fixed (and not a varying) Percentage
         Share in its Loans and Note and be committed to make that Percentage
         Share of all future Loans, the assignee shall have a fixed Percentage
         Share in such Loans and Note and be committed to make that Percentage
         Share of all future Loans, and the Percentage Share of the Maximum Loan
         Amount of both the assignor and assignee shall equal or exceed
         $5,000,000.

                  (ii) The parties to each such assignment shall execute and
         deliver to Agent, for its acceptance and recording in the "Register"
         (as defined below in this section), an Assignment and Acceptance in the
         form of Exhibit G, appropriately completed, together with the Note
         subject to such assignment and a processing fee payable to Agent of
         $3,500. Upon such execution, delivery, and payment and upon the
         satisfaction of the conditions set out in such Assignment and
         Acceptance, then (i) Borrower shall issue new Notes to such assignor
         and assignee upon return of the old Notes to Borrower, and (ii) as of
         the "Settlement Date" specified in such Assignment and Acceptance the
         assignee thereunder shall be a party hereto and a Lender hereunder and
         Agent shall thereupon deliver to Borrower and each Lender a schedule
         showing the revised Percentage Shares of such assignor Lender and such
         assignee Lender and the Percentage Shares of all other Lenders.

                  (iii) Each assignee Lender which is not a United States person
         (as such term is defined in Section 7701(a)(30) of the Internal Revenue
         Code of 1986, as amended) for







                                       69
<PAGE>   70

         Federal income tax purposes, shall (to the extent it has not already
         done so) provide Agent and Borrower with the "Prescribed Forms"
         referred to in Section 3.6(d).

         (d) Nothing contained in this section shall prevent or prohibit any
Lender from assigning or pledging all or any portion of its Loans and Note to
any Federal Reserve Bank 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 Bank; provided that no such assignment or pledge
shall relieve such Lender from its obligations hereunder.

         (e) By executing and delivering an Assignment and Acceptance, each
assignee Lender thereunder will be confirming to and agreeing with Borrower,
Agent and each other Lender hereunder that such assignee understands and agrees
to the terms hereof, including Article IX hereof.

         (f) Agent shall maintain a copy of each Assignment and Acceptance and a
register for the recordation of the names and addresses of Lenders and the
Percentage Shares of, and principal amount of the Loans owing to, each Lender
from time to time (in this section called the "Register"). The entries in the
Register shall be conclusive, in the absence of manifest error, and Borrower and
each Bank Party may treat each Person whose name is recorded in the Register as
a Lender hereunder for all purposes. The Register shall be available for
inspection by Borrower or any Bank Party at any reasonable time and from time to
time upon reasonable prior notice.

         Section 10.6. Confidentiality. Each Bank Party agrees that it will take
all reasonable steps to keep confidential any proprietary information given to
it by any Restricted Person, provided, however, that this restriction shall not
apply to information which (i) has at the time in question entered the public
domain, (ii) is required to be disclosed by Law (whether valid or invalid) of
any Tribunal, (iii) is disclosed to any Bank Party's Affiliates, auditors,
attorneys, or agents, (iv) is furnished to any other Bank Party or to any
purchaser or prospective purchaser of participations or other interests in any
Loan or Loan Document, or (v) is disclosed in the course of enforcing its rights
and remedies during the existence of an Event of Default.

         Section 10.7. Governing Law; Submission to Process. EXCEPT TO THE
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN
DOCUMENT, THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE
UNDER THE LAWS OF THE STATE OF TEXAS AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF
THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.
CHAPTER 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN REVOLVING CREDIT
LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) DOES NOT APPLY TO THIS AGREEMENT
OR TO THE NOTES. BORROWER AND EACH GUARANTOR HEREBY IRREVOCABLY SUBMITS ITSELF
TO THE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN THE STATE OF
TEXAS AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY
LEGAL PROCEEDING RELATING TO THE LOAN DOCUMENTS OR THE OBLIGATIONS BY ANY MEANS
ALLOWED UNDER TEXAS OR FEDERAL LAW. ANY LEGAL PROCEEDING ARISING OUT OF OR IN
ANY WAY RELATED TO ANY OF THE LOAN DOCUMENTS SHALL BE BROUGHT AND LITIGATED
EXCLUSIVELY IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF






                                       70
<PAGE>   71

TEXAS, DALLAS DIVISION, TO THE EXTENT IT HAS SUBJECT MATTER JURISDICTION, AND
OTHERWISE IN THE TEXAS DISTRICT COURTS SITTING IN DALLAS COUNTY, TEXAS. THE
PARTIES HERETO HEREBY WAIVE AND AGREE NOT TO ASSERT, BY WAY OF MOTION, AS A
DEFENSE OR OTHERWISE, THAT ANY SUCH PROCEEDING IS BROUGHT IN AN INCONVENIENT
FORUM OR THAT THE VENUE THEREOF IS IMPROPER, AND FURTHER AGREE TO A TRANSFER OF
ANY SUCH PROCEEDING TO A FEDERAL COURT SITTING IN THE STATE OF TEXAS TO THE
EXTENT THAT IT HAS SUBJECT MATTER JURISDICTION, AND OTHERWISE TO A STATE COURT
IN DALLAS, TEXAS. IN FURTHERANCE THEREOF, BORROWER AND BANK PARTIES EACH HEREBY
ACKNOWLEDGE AND AGREE THAT IT WAS NOT INCONVENIENT FOR THEM TO NEGOTIATE AND
RECEIVE FUNDING OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT IN SUCH
COUNTY AND THAT IT WILL BE NEITHER INCONVENIENT NOR UNFAIR TO LITIGATE OR
OTHERWISE RESOLVE ANY DISPUTES OR CLAIMS IN A COURT SITTING IN SUCH COUNTY.

         Section 10.8. Limitation on Interest. Bank Parties, Borrower,
Guarantors and any other parties to the Loan Documents intend to contract in
strict compliance with applicable usury Law from time to time in effect. In
furtherance thereof such Persons stipulate and agree that none of the terms and
provisions contained in the Loan Documents shall ever be construed to create a
contract to pay, for the use, forbearance or detention of money, interest in
excess of the maximum amount of interest permitted to be charged by applicable
Law from time to time in effect. Neither any Borrower or Guarantors nor any
present or future guarantors, endorsers, or other Persons hereafter becoming
liable for payment of any Obligation shall ever be liable for unearned interest
thereon or shall ever be required to pay interest thereon in excess of the
maximum amount that may be Lawfully charged under applicable Law from time to
time in effect, and the provisions of this section shall control over all other
provisions of the Loan Documents which may be in conflict or apparent conflict
herewith. Bank Parties expressly disavow any intention to charge or collect
excessive unearned interest or finance charges in the event the maturity of any
Obligation is accelerated. If (a) the maturity of any Obligation is accelerated
for any reason, (b) any Obligation is prepaid and as a result any amounts held
to constitute interest are determined to be in excess of the legal maximum, or
(c) any Bank Party or any other holder of any or all of the Obligations shall
otherwise collect moneys which are determined to constitute interest which would
otherwise increase the interest on any or all of the Obligations to an amount in
excess of that permitted to be charged by applicable Law then in effect, then
all sums determined to constitute interest in excess of such legal limit shall,
without penalty, be promptly applied to reduce the then outstanding principal of
the related Obligations or, at such Bank Party's or holder's option, promptly
returned to Borrower or the other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable Law, Bank
Parties and Borrower and Guarantors (and any other payors thereof) shall to the
greatest extent permitted under applicable Law, (i) characterize any
non-principal payment as an expense, fee or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable Law in order to
Lawfully charge the maximum amount of interest permitted under applicable Law.
In the event applicable Law provides for an interest ceiling under Section 303
of the Texas Finance Code (the "Texas Finance Code") for that day, the ceiling
shall






                                       71
<PAGE>   72

be the "weekly ceiling" as defined in the Texas Finance Code, provided that if
any applicable Law permits greater interest, the Law permitting the greatest
interest shall apply. As used in this section the term "applicable Law" means
the Laws of the State of Texas or the Laws of the United States of America,
whichever Laws allow the greater interest, as such Laws now exist or may be
changed or amended or come into effect in the future.

         Section 10.9. Termination; Limited Survival. In its sole and absolute
discretion Borrower may at any time that no Obligations are owing elect in a
written notice delivered to Agent to terminate this Agreement. Upon receipt by
Agent of such a notice, if no Obligations are then owing this Agreement and all
other Loan Documents shall thereupon be terminated and the parties thereto
released from all prospective obligations thereunder. Notwithstanding the
foregoing or anything herein to the contrary, any waivers or admissions made by
any Borrower or any Guarantor in any Loan Document, any Obligations under
Sections 3.2 through 3.6, and any obligations which any Person may have to
indemnify or compensate any Bank Party shall survive any termination of this
Agreement or any other Loan Document. At the request and expense of Borrower,
Agent shall prepare and execute all necessary instruments to reflect and effect
such termination of the Loan Documents. Agent is hereby authorized to execute
all such instruments on behalf of all Lenders, without the joinder of or further
action by any Lender.

         Section 10.10. Severability. If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

         Section 10.11. Counterparts. This Agreement may be separately executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

         Section 10.12. Waiver of Jury Trial, Punitive Damages, etc. BORROWER
AND EACH BANK PARTY HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND
IRREVOCABLY (A) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH
THE LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED
THEREWITH, BEFORE OR AFTER MATURITY; (B) WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH
LITIGATION ANY "SPECIAL DAMAGES", AS DEFINED BELOW, (C) CERTIFIES 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 (D)
ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER
LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.
AS USED IN THIS SECTION, "SPECIAL DAMAGES" INCLUDES ALL SPECIAL, CONSEQUENTIAL,
EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE
ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR
DELIVER TO ANY OTHER PARTY HERETO.

         FOR VALUE RECEIVED, the undersigned, Chesapeake Exploration Limited
Partnership, an Oklahoma limited partnership (herein called "Borrower"), hereby
promises to pay to the order of Union Bank of California, N.A., a national

Eurodollar Loan to but not including such Eurodollar Rate Payment Date. After
the occurrence and during the continuance of an Event of Default and a notice to
Borrower by Agent that the Default Rate shall apply, all Loans shall bear
interest on each day outstanding at the Default Rate in effect on such day, and
such interest shall be due and payable daily as it accrues. Notwithstanding the
foregoing provisions of this paragraph: (a) this Note shall never bear interest
in excess of the Highest Lawful Rate, and (b) if at any time the rate at which
interest is payable on this Note is limited by the Highest Lawful Rate (by the
foregoing clause (a) or by reference to the Highest Lawful Rate in the
definitions of Base Rate, Eurodollar Rate and Default Rate), this Note shall
bear interest at the Highest Lawful Rate and shall continue to bear interest at
the Highest Lawful Rate until such time as the total amount of interest accrued
hereon equals (but does not exceed) the total amount of interest which would
have accrued hereon had there been no Highest Lawful Rate applicable hereto.

         Notwithstanding the foregoing paragraph and all other provisions of
this Note, in no event shall the interest payable hereon, whether before or
after maturity, exceed the maximum amount of interest which, under applicable
law, may be charged on this Note, and this Note is expressly made subject to the
provisions of the Credit Agreement which more fully set out the limitations on
how interest accrues hereon. In the event applicable law provides for a ceiling
under Section 303 of the Texas Finance Code, that ceiling shall be the weekly
ceiling and shall be used in this Note for calculating the Highest Lawful Rate
and for all other purposes. The term "applicable law" as used in this Note shall
mean the laws of the State of Texas or the laws of the United States, whichever
laws allow the greater interest, as such laws now exist or may be changed or
amended or come into effect in the future.

         If this Note is placed in the hands of an attorney for collection after
default, or if all or any part of the indebtedness represented hereby is proved,
established or collected in any court or in any bankruptcy, receivership, debtor
relief, probate or other court proceedings, Borrower and all endorsers, sureties
and guarantors of this Note jointly and severally agree to pay reasonable

attorneys' fees and collection costs to the holder hereof in addition to the
principal and interest payable hereunder.

         Borrower and all endorsers, sureties and guarantors of this Note hereby
severally waive demand, presentment, notice of demand and of dishonor and
nonpayment of this Note, protest, notice of protest, notice of intention to
accelerate the maturity of this Note, declaration or notice of acceleration of
the maturity of this Note, diligence in collecting, the bringing of any suit
against any party and any notice of or defense on account of any extensions,
renewals, partial payments or changes in any manner of or in this Note or in any
of its terms, provisions and covenants, or any releases or substitutions of any
security, or any delay, indulgence or other act of any trustee or any holder
hereof, whether before or after maturity.
