Lender under such section, does not exceed such Lender's Percentage Share of the
Borrowing Base then outstanding and (c) the aggregate amount of all Revolving
Loans outstanding plus all LC Obligations does not exceed the Borrowing Base
then outstanding. The aggregate amount of all Revolving Loans requested of all
Lenders in any Request for Advance must be greater than or equal to $500,000 (or
a higher integral multiple of $100,000) or, subject to the $500,000 minimum
aggregate amount applicable to any LIBOR Tranche in any Rate Election, may equal
the unadvanced portion of the Borrowing Base or an amount required to finance
the reimbursement of an LC Disbursement as contemplated by Section 3.3. Subject
to provisions of this Agreement, the Revolving Loans may be prepaid and
reborrowed prior to the Conversion Date.

         (b) Term Loans. Each Lender severally agrees, on the terms and
             ----------
conditions set forth herein, to make a loan to the Borrower (each such loan, a
"Term Loan") such that, on the Conversion Date such Lender's Revolving Loans and
 ---------
Matured LC Obligations shall be converted, in whole or in part, into a Term Loan
in the amount of such Lender's Percentage Share of the aggregate amount of all
Revolving Loans plus all Matured LC Obligations, or such lesser amount as the
Borrower may request. Each Lender's obligation to make a Term Loan is subject to
the condition that (a) the sum of (i) the aggregate principal amount of the Term
Loan which such Lender shall be requested to make hereunder to the Borrower plus
(ii) the Maximum Drawing Amount for which such Lender is liable to purchase
participations under Section 3.3(c), shall not exceed such Lender's Percentage
Share of the Borrowing Base, as in effect on the Conversion Date. Revolving
Loans which are LIBOR Rate Loans with Interest Periods ending after the
Conversion Date shall be continued as Term Loans which are LIBOR Rate Loans with
the same Interest Period. Amounts borrowed as Term Loans which are repaid or
prepaid by the Borrower may not be reborrowed. After making its Term Loan
pursuant to this clause (b), no Lender shall have any further commitment to
lend, except for its obligations to participate in or make Loans with respect to
any Matured LC Obligation arising after the Conversion Date with respect to a
Letter of Credit in effect on the Conversion Date pursuant to Sections 3.3(a)
and 3.3(c).

         (c) Notes. The obligation of Borrower to repay to each Lender the
             -----
aggregate amount of all Revolving Loans and the Term Loan made by such Lender
(such Lender's "Loan"), together with interest accruing in connection therewith,
                ----
shall be evidenced by a single promissory note (such Lender's "Note") made by
                                                               ----
Borrower payable to the order of such Lender in the form of Exhibit A with
                                                            ---------
appropriate insertions. 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; provided that, for purposes of calculating the principal
outstanding pursuant to its Note, the proceeds of the Term Loan made by any
Lender shall be deemed to be applied to the repayment of Revolving Loans on the
Conversion Date. Interest on each Note shall accrue and be due and payable as
provided herein and therein. The entire unpaid principal balance of the Loans
and all interest accrued thereon shall be due and payable in full on the Final
Maturity Date.

         Section 2.2 Extension of Conversion Date and of Commitments.
                     -----------------------------------------------

         (a) Subject to the other provisions of this Agreement, each Lender's
commitment to make Revolving Loans shall be effective for an initial period from
the Closing Date to the Original Conversion Date; provided that the Conversion
Date, and concomitantly such commitments and the Final Maturity Date, may be
extended for successive 364 day periods, each expiring on the date which is 364
days from the then scheduled Conversion Date or Final Maturity Date (as the case
may be). If Borrower shall request in a Certificate of Extension delivered to
the Administrative Agent not more than sixty (60) days and not less than
forty-five (45) days prior to the Conversion Date that the Conversion Date be
extended for 364 days from the then scheduled Conversion Date, then the
Administrative Agent shall promptly notify each Lender of such request and each
Lender shall notify the Administrative Agent in writing, no later than thirty
(30) days after receipt by the Lenders of the Certificate of Extension, whether
such Lender, in the exercise of its sole discretion, will extend the Conversion
Date for such 364 day period. Any Lender which shall not timely notify the
Administrative Agent whether it will extend the Conversion Date shall be deemed
to not have agreed to extend the Conversion Date. No Lender shall have any
obligation whatsoever to agree to extend the Conversion Date. Any agreement to
extend the Conversion Date by any Lender shall be irrevocable, except as
provided in clause (c) of this Section.
            ----------

         (b) If all Lenders notify the Administrative Agent pursuant to clause
                                                                        ------
(a) of this Section of their agreement to extend the Conversion Date, then the
---
Administrative Agent shall so notify each Lender and Borrower, and such
extension shall be effective without other or further action by any party hereto
and the Conversion Date and the Final Maturity Date shall be extended for an
additional 364 day period.

         (c) If any Lenders approve the extension of the then scheduled
Conversion Date (such Lenders agreeing to extend the Conversion Date herein
called the "Accepting Lenders") and if one or more Lenders shall notify, or be
            -----------------
deemed to notify, the Administrative Agent pursuant to clause (a) of this
                                                       ----------
Section that they will not extend the then scheduled Conversion Date (such
Lenders herein called the "Declining Lenders"), then (A) the Administrative
                           -----------------
Agent shall promptly so notify the Borrower and the Accepting Lenders and the
Declining Lenders; (B) the Accepting Lenders shall,

                                       21
<PAGE>

upon Borrower's election to extend the then scheduled Conversion Date as set
forth in clause (i) below, extend the then scheduled Conversion Date; and (C)
         ----------
Borrower shall, pursuant to a notice delivered to the Administrative Agent, the
Accepting Lenders and the Declining Lenders, no later than the tenth (10th) day
following the date by which each Lender is required pursuant to clause (a) of
                                                                ----------
this Section to approve or disapprove the requested extension of the total
Commitments, either:

                  (i) elect to extend the Conversion Date with respect to the
         Accepting Lenders. Upon such election, the Borrower shall, and, prior
         to or no later than the then scheduled Conversion Date, (A) replace
         each of the Declining Lenders with another lender or lenders reasonably
         acceptable to the Administrative Agent (such lenders herein called the
         "Replacement Lenders") and (B) the Replacement Lender or Replacement
          -------------------
         Lenders shall purchase, and the Declining Lender or Declining Lenders
         shall sell, all of each Declining Lender's or Declining Lenders' rights
         and obligations hereunder without recourse or expense to, or warranty
         by, such Declining Lender or Declining Lenders being replaced for a
         purchase price equal to the aggregate outstanding principal amount of
         the Obligations payable to such Declining Lender or Declining Lenders
         plus any accrued but unpaid interest on such Obligations and accrued
         but unpaid fees or other amounts owing in respect of such Declining
         Lender's or Declining Lenders' Loans and Commitments hereunder. Upon
         the payment of such amounts to the Administrative Agent on behalf of
         the Declining Lenders and the execution of an Agreement to be Bound, by
         the Replacement Lender or Replacement Lenders and the Declining Lender
         or Declining Lenders (which each such Declining Lender agrees to
         execute promptly), the Replacement Lender or Replacement Lenders shall
         each constitute a Lender hereunder and the Declining Lender or
         Declining Lenders being so replaced shall no longer constitute a
         Lender, and shall no longer have any obligations hereunder, other than
         to the Administrative Agent pursuant to Article IX; or
                                                 ----------

                  (ii) elect to revoke and cancel the extension request in such
         Certificate of Extension by giving notice of such revocation and
         cancellation to the Administrative Agent (which shall promptly notify
         the Lenders thereof) no later than the tenth (10th) day following the
         date by which each Lender is required, pursuant to clause (a) of this
                                                            ----------
         Section, to approve or disapprove the requested extension of the
         Conversion Date, and concomitantly the commitments of the Lenders to
         make Revolving Loans and the Final Maturity Date.

         If Borrower fails to timely provide the election notice referred to in
this clause (c), Borrower shall be deemed to have revoked and canceled the
     ----------
extension request in the Certificate of Extension and to have elected not to
extend the Conversion Date, and, on the then scheduled Conversion Date, subject
to the provisions of this Agreement, the Revolving Loans and Matured LC
Obligations of the Borrower shall be deemed repaid with the proceeds of Term
Loans.

         Section 2.3 [Reserved].

         Section 2.4 Requests for Loans. Borrower must give to Administrative
                     ------------------
Agent not later than 11:00 am., Central time, at least one Business Day's prior
written notice of any requested Revolving Loans which shall bear interest at the
Base Rate and not later than 11:00 a.m., Central

                                       22
<PAGE>

time, at least three Business Day's prior written notice of any requested
Revolving Loans which shall bear interest at the Adjusted LIBOR Rate, after
which Administrative Agent shall give each Lender prompt notice thereof. Each
such written request must be made in the form and substance of the "Request for
Advances" attached hereto as Exhibit C, duly completed. If all conditions
                             ---------
precedent to such Revolving Loans have been met, each Lender will not later than
12:00 noon, Central time, on the date requested promptly remit to Administrative
Agent at Administrative Agent's office at 909 Fannin, Suite 1700, Houston,
Houston, Texas 77010, the amount of such Lender's Revolving Loans in immediately
available funds, and upon receipt of such funds, unless to its actual knowledge
any conditions precedent to such Revolving Loans have been neither met nor
waived as provided herein, Administrative Agent shall promptly make the
Revolving Loans available to Borrower in immediately available funds. Each
Request for Revolving Loans shall be irrevocable and binding on Borrower. Unless
Administrative Agent shall have received prompt notice from a Lender that such
Lender will not make available to Administrative Agent such Lender's Revolving
Loans, Administrative Agent may in its discretion assume that such Lender has
made such Revolving Loans available to Administrative Agent in accordance with
this section and Administrative Agent may if it chooses, in reliance upon such
assumption, make such Revolving Loan available to Borrower. If and to the extent
such Lender shall not so make its Revolving Loan available to Administrative
Agent, such Lender and Borrower severally agree to pay or repay to
Administrative Agent within two Business Days after demand the amount of such
Revolving Loan together with interest thereon, for each day from the date such
amount is made available to Borrower until the date such amount is paid or
repaid to Administrative Agent, to be calculated as to such Lender at the
Federal Funds Rate, and to be calculated as to Borrower at the interest rate
applicable at the time to the other Revolving Loans made on such date. If any
Lender fails to make such payment to Administrative Agent within such two
Business Day period, such Lender shall in addition to such amount pay interest
thereon, for each day from the date such Revolving Loan is made available to
Borrower until the date such amount is paid or repaid to Administrative Agent,
at the interest rate applicable at the time to the other Revolving Loans made on
such date. The failure of any Lender to make any Revolving Loan to be made by it
hereunder shall not relieve any other Lender of its obligation hereunder, if
any, to make its Revolving Loan, but no Lender shall be responsible for the
failure of any other Lender to make any Revolving Loan to be made by such other
Lender.

         Section 2.5 Use of Proceeds. Borrower shall use all funds from Loans
                     ---------------
for general corporate purposes in its existing lines of business (which include
the exploration, operation and development of oil and gas properties) and
acquisition of oil and gas reserves. In no event shall the funds from any Loan
or Letter of Credit be used directly or indirectly by any Person for personal,
family, household or agricultural purposes or for the purpose, whether
immediate, incidental or ultimate, of purchasing, acquiring or carrying any
"margin stock" or any "margin" securities; (as such terms are defined
respectively 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 or
margin securities. Borrower represents and warrants to Lenders 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 or margin securities.

         Section 2.6 Rate Elections: Interest Rates.
                     ------------------------------

         (a) Borrower may from time to time designate all or any portions of the
Loans (including any yet to be made Loans which are to be made prior to or at
the beginning of the designated Interest Period but excluding any portions of
the Loans which are required to be repaid prior to the end of the designated
Interest Period) as a "LIBOR Tranche", which term refers to a set of LIBOR Rate
Portions with identical Interest Periods and with each Lender participating in
such LIBOR Tranche in accordance with its Percentage Share. Borrower may make no
such election during the continuance of a Default and Borrower may make such an
election with respect to already existing LIBOR Rate Portions only if such
election will take effect at or after the termination of the Interest Period
applicable thereto. Each election by Borrower of a LIBOR Tranche shall:

                  (i)   Be made in writing in the form and substance of the
         "Rate Election" attached hereto as Exhibit D, duly completed;
                                            ---------

                  (ii)  Specify the aggregate amount of the Loans which Borrower
         desires to designate as such LIBOR Tranche, the first day of the
         Interest Period which is to apply thereto, and the length of such
         Interest Period; and

                  (iii) Be received by Administrative Agent not later than 11:00
         a.m., Central time, on the third Business Day preceding the first day
         of the specified Interest Period.

Promptly after receiving any such election (a "Rate Election" ) which meets the
                                               -------------
requirements of this section, Administrative Agent shall notify each Lender
thereof. Each Rate Election shall be irrevocable. Borrower may make no Rate
Election which does not specify an Interest Period complying with the definition
of "Interest Period" in Section 1.1, and the aggregate amount of the LIBOR
Tranche elected in any Rate Election must be $500,000 or a higher integral
multiple of $100,000. Upon the termination of each Interest Period the portion
of each Loan within the related LIBOR Tranche shall, unless the subject of a new
Rate Election then taking effect, automatically become a part of the Base Rate
Portion of such Loan and become subject to all provisions of the Loan Documents
governing such Base Rate Portion. Borrower shall have no more than nine (9)
LIBOR Tranches in effect at any time; provided, however, that for purposes of
calculating such limitation, any LIBOR Tranche as to which all Lenders have not
participated shall not be included.

         (b) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and upon the Final Maturity Date; provided
that (i) interest accrued at the Late Payment Rate shall be payable on demand,
(ii) in the event of any repayment or prepayment of any Loan (other than
repayment of Revolving Loans deemed to be made with the proceeds of a Term Loan
on the Conversation Date), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii)
in the event of any conversion of any LIBOR Loan prior to the end of the current
Interest Period therefor, accrued interest on such Loan shall be payable on the
Closing Date of such conversion.

                     ---------------
commitment to make Revolving Loans, during the period from the Closing Date
through the Conversion Date, Borrower will pay to Administrative Agent for the
account of each Lender a commitment fee determined on a daily basis by applying
the applicable Commitment Fee Rate to such Lender's Percentage Share of the
unused portion of the Borrowing Base on each day, determined for each such day
by deducting from the amount of the Borrowing Base at the end of such day the
sum of (i) the aggregate unpaid principal balance of the Revolving Loans at the
end of such day plus (ii) the amount of all LC Obligations at the end of such
day. This commitment fee shall be due and payable in arrears, with the first
payment due on September 30, 2000, and thereafter on the last day of each
Fiscal Quarter and on the Conversion Date.

         Section 2.8 Administrative Agent's Fees. Borrower agrees to pay to the

full the unpaid principal amount of each Loan on the Final Maturity Date.

         (a) Term Loan Repayments. Borrower shall, on each Term Loan Payment
             --------------------
Date, make a scheduled repayment of all Term Loans and/or a contribution of LC
Collateral as set forth in Section 3.6(a) in an aggregate amount equal to the
lesser of (i) one-fourth of the aggregate principal of the Term Loans made on
the Conversion Date plus the Maximum Drawing Amount in effect on the Conversion
Date and (ii) the principal of all Loans outstanding on such Term Loan Payment
Date plus the Maximum Drawing Amount in effect on such Term Loan Payment Date;
provided that to the extent that the termination or expiration of any Letter of
Credit shall reduce the sum of (x) Term Loans plus (y) LC Obligations, the
repayment required on the Term Loan Payment Date following such reduction shall
be reduced by an amount equal to such reduction.

         (b) Mandatory Prepayments. Borrower shall make the following
             ---------------------
prepayments of the Loans:

             (i) Borrowing Base Deficiency. If at any time the aggregate unpaid
                 -------------------------
         principal balance of the Loans plus the aggregate amount of LC
         Obligations exceeds the Borrowing Base (the "Borrowing Base
                                                      --------------
         Deficiency"), Borrower shall, within thirty (30) days after
         ----------
         Administrative Agent sends written notice of such fact to Borrower,
         either (1) prepay the principal of the Loans (and, upon repayment of
         all Loans, shall provide LC Collateral as set forth in Section 3.6) in
         an aggregate amount at least equal to such Borrowing Base Deficiency
         (in this section, a "Mandatory Prepayment Amount"), or (2) give notice
                              ---------------------------
         to Administrative Agent electing to prepay such Mandatory Prepayment
         Amount in three (3) (or fewer) monthly installments, or (3) within
         thirty (30) days after receipt of notice of such Borrowing Base
         Deficiency, deliver to the Administrative Agent such deeds of trust and
         mortgages, in form and substance satisfactory to Administrative Agent,
         on oil and gas properties of the Borrower not then currently included
         in the Borrowing Base and having,

                                       25
<PAGE>

         in the sole and absolute discretion of the Lenders, an incremental
         Borrowing Base value at least equal to one hundred percent (100%) of
         such Borrowing Base Deficiency, or (4) will cure such Borrowing Base
         Deficiency by a combination of the actions required by this Section
         2.10(b)(i), within the time periods required thereby. Each such
         installment shall equal or exceed one-third of such Borrowing Base
         Deficiency; the first such installment shall be paid with in sixty (60)
         days of the giving of such notice by the Borrower and the subsequent
         installments shall be due and payable at one month intervals thereafter
         until such Borrowing Base Deficiency has been eliminated.

               (ii)    Net Sales Proceeds of Asset Sales.
                       ---------------------------------

                       (A) Borrower shall prepay the Loans or provide LC
               Collateral in an aggregate amount equal to 100% of the Net Sales
               Proceeds from the sale of any property included in the Borrowing
               Base except pursuant to the first sentence of Section 6.2(d)(iii)
               within one (1) Business Day of receipt of any such net proceeds.
               Such prepayments shall be applied first to the principal of the
               Loans until the Loans are paid in full and then shall be held as
               LC Collateral in an amount equal to the aggregate amount of LC
               Obligations pursuant to Section 3.6.

                       (B) In the event a Borrowing Base Deficiency exists and
               is continuing, Borrower shall prepay the Loans in an amount equal
               to such Borrowing Base Deficiency from the Net Sales Proceeds
               from the sale of any property (excluding sales of inventory in
               the ordinary course) not included in the Borrowing Base within
               one (1) Business Day of receipt of any such net proceeds.
               Application of such Net Sales Proceeds shall be applied to the
               principal of the Loans until the Loans are paid in full and then
               shall be held as LC Collateral in an amount equal to the
               aggregate amount of LC Obligations pursuant to Section 3.6.

         (c)   Optional Prepayments. Borrower may, upon one Business Day's
               --------------------
notice to Administrative Agent, 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 $500,000 or any higher
integral multiple of $100,000 or the outstanding balance on the applicable
Notes, if less. Such prepayments shall be applied as directed by Borrower.

         (d)   General Provisions Regarding Payments. Each prepayment of
               -------------------------------------
principal of the Loans 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; provided that, if any payment made on a Term Loan Payment
Date pursuant to clause (a) shall eliminate an existing Borrowing Base
Deficiency, additional payments pursuant to clause (b) shall not be required so
long as no Borrowing Base Deficiency shall exist.

         Section 2.11 Payments to Lenders. Borrower will make each payment
                      -------------------
which it owes under the Loan Documents to Administrative Agent for the account
of the Lender to whom such payment

                                       26
<PAGE>

is owed. Each such payment must be received by Administrative Agent not later
than 11:00 a.m., Central 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
Administrative 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. When Administrative Agent collects or receives money on account of the
Obligations, Administrative Agent shall distribute all money so collected or
received, and Lenders shall apply all such money they receive from
Administrative Agent, 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 Administrative Agent under Section 6.1(i) or 8.3 or Issuing
Bank under Section 3.3(a), and then to the partial payment of all other
Obligations then due in proportion to the amounts thereof, or as Lenders 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;

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

         (d) then, for the payment or prepayment of any other Obligations; and

         (e) last, for the pro rata payment of any other indebtedness or
obligations to Lenders secured by the Security Documents.

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
2.10. All distributions of amounts described in any of subsections (b), (c) or
(d) above shall be made by Administrative Agent pro rata to Administrative Agent
and each Lender then owed Obligations described in such subsection in proportion
to all amounts owed to Administrative Agent and all Lenders which are described
in such subsection; provided that if any Lender then owes payments to Issuing
Bank for the purchase of a participation under Section 3.3(c) hereof, any
amounts otherwise distributable under this section to such Lender shall be
deemed to belong to Issuing Bank, to the extent of such unpaid payments, and
Administrative Agent shall apply such amounts to make such unpaid payments
rather than such amounts to such Lender.

         Section 2.12 Initial Borrowing Base. During the period from the date
                      ----------------------
hereof to the first Evaluation Date the Borrowing Base shall be $40,000,000.

         Section 2.13 Subsequent Determinations of Borrowing Base.
                      -------------------------------------------

         (a) By each Evaluation Date Borrower shall furnish to each Lender all
information, reports and data which Administrative Agent has then reasonably
requested concerning Related Persons' businesses and properties (including
Related Persons' oil and gas properties and interests and the reserves and
production relating thereto), together with the Engineering Report described in
Section 6.1(b)(iv), if an Engineering Report is then due. Within thirty (30)
days after receiving such information, reports and data, or as promptly
thereafter as practicable, all Lenders shall agree upon an amount for the
Borrowing Base, which, if all Lenders do not agree on such amount, shall be the
lowest amount determined by any Lender, and Administrative Agent shall by 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 (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, Administrative Agent may
nonetheless designate the Borrowing Base at any amount which Lenders determine,
and may redesignate the Borrowing Base from time to time thereafter at any
amount which all Lenders redetermine, until each Lender receives all such
information, reports and data, whereupon Lenders shall designate a new Borrowing
Base as described above. Lenders shall determine the amount of the Borrowing
Base based upon the loan collateral value which they, in their sole discretion
and in accordance with their respective normal practices and standards for oil
and gas loans as such practices and standards exist at the particular time,
assign to the various oil and gas properties of Related Persons at the time in
question and based upon such other factors (including without limitation the
assets, liabilities, fixed charges, cash flow, business, properties, prospects,
management and ownership of Borrower and its Related Persons) as they, in their
sole discretion and in accordance with their respective normal practices and
standards for oil and gas loans as such practices and standards exist at the
particular time, deem significant. It is expressly understood that Lenders and
Administrative 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
2.7(a) and, to the extent permitted by law and regulatory authorities, for the
purposes of Section 2.15. Semiannual redeterminations and additional
redeterminations at the request of the Lenders or Administrative Agent shall be
at no cost to Borrower. Additional redeterminations at Borrower's request shall
be subject to a $5,000 engineering fee payable by Borrower to the Administrative
Agent for its own account.

         (b) The Borrower may include additional oil and gas properties of the
Borrower acquired from time to time as Collateral for the Obligations, which may
then be included in the calculation of the Borrowing Base, by the Borrower (A)
giving written notice to the Administrative Agent of such properties to be
included, (B) subjecting such properties to liens securing the Obligations
(pursuant to Security Documents satisfactory to the Administrative Agent), (C)
including such properties in an Engineering Report submitted to the
Administrative Agent and (D) delivering to the Administrative Agent title
opinions addressed to the Administrative Agent for the benefit of the Lenders
covering all of such properties and other legal opinions from counsel acceptable
to the

                                       28
<PAGE>

Administrative Agent, in its sole discretion, in form, scope and substance
acceptable to the Administrative Agent opining favorably as to, among such other
matters as may be required by the Administrative Agent, (1) the Borrower's
ownership of such properties and (2) matters of the type covered by the opinions
delivered pursuant to Section 4.1 (m) and the opinion attached hereto as Exhibit
                                                                         -------
F.
-

         (c) In addition to the any scheduled determination or discretionary
determination of the Borrowing Base, the Borrowing Base shall be redetermined
upon the sale or transfer of any oil and gas property of the Borrower included
in the Borrowing Base in an amount as required by Section 6.2(d)(iii).

         Section 2.14 Borrower's Reduction of Borrowing Base. Until the
                      --------------------------------------
Conversion Date Borrower may, during the fifteen-day period beginning on each
Determination Date (each such period in this section, an "Option Period"),
                                                          -------------
reduce the Borrowing Base from the amount designated by Administrative Agent to
any lesser amount. To exercise such option Borrower must within an Option Period
send notice to Administrative 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
Administrative 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 the next date as of which the Borrowing Base
is redetermined.

         Section 2.15 Alternate Rate of Interest. If prior to the commencement
                      --------------------------
of any Interest Period for a LIBOR Rate Portion:

         (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not
exist for ascertaining the Adjusted LIBOR Rate or the LIBOR Rate, as applicable,
for such Interest Period; or

         (b) the Administrative Agent is advised by the Majority Lenders that
the Adjusted LIBOR Rate for such Interest Period will not adequately and fairly
reflect the cost to such Lenders (or Lender) of making or maintaining their
Loans (or its Loan) included in such LIBOR Rate Portion for such Interest
Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Lenders that the circumstances
giving rise to such notice no longer exist, (i) any Rate Election that requests
the conversion of any Base Rate Portion to, or continuation of any LIBOR Rate
Portion as, a LIBOR Rate Portion shall be ineffective and (ii) any requests for
a Loan as a LIBOR Rate Portion shall be made as a Base Rate Portion.

         Section 2.16 Increased Costs. (a) If any Change in Law shall:
                      ---------------

                  (i) impose, modify or deem applicable any reserve, special
         deposit or similar requirement against assets of, deposits with or for
         the account of, or credit extended by, any Lender (except any such
         reserve requirement reflected in the Adjusted LIBOR Rate) or the
         Issuing Bank; or

                  (ii) impose on any Lender or the Issuing Bank or the London
         interbank market any other condition affecting this Agreement or LIBOR
         Rate Loans made by such Lender or any Letter of Credit or participation
         therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any LIBOR Rate Loan (or of maintaining its
obligation to make any such Loan) or to increase the cost to such Lender or the
Issuing Bank of participating in, issuing or maintaining any Letter of Credit or
to reduce the amount of any sum received or receivable by such Lender or the
Issuing Bank hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, such
additional amount or amounts as will compensate such Lender or the Issuing Bank,
as the case may be, for such additional costs incurred or reduction suffered.

         (b) If any Lender or the Issuing Bank determines that any Change in Law
regarding capital requirements has or would have the effect of reducing the rate
of return on such Lender's or the Issuing Bank's capital or on the capital of
such Lender's or the Issuing Bank's holding company, if any, as a consequence of
this Agreement or the Loans made by, or participations in Letters of Credit held
by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level
below that which such Lender or the Issuing Bank or such Lender's or the Issuing
Bank's holding company could have achieved but for such Change in Law (taking
into consideration such Lender's or the Issuing Bank's policies and the policies
of such Lender's or the Issuing Banks holding company with respect to capital
adequacy), then from time to time the Borrower will pay to such Lender or the
Issuing Bank, as the case may be, such additional amount or amounts as will
compensate such Lender or the Issuing Bank or such Lender's or the Issuing Banks
holding company for any such reduction suffered.

         (c) A certificate of a Lender or the Issuing Bank setting forth in
reasonable detail the amount or amounts necessary to compensate such Lender or
the Issuing Bank or its holding company, as the case may be, as specified in
paragraph (a) or (b) of this Section shall be delivered to the Borrower and
shall be conclusive absent manifest error. The Borrower shall pay such Lender or
the Issuing Bank, as the case may be, the amount shown as due on any such
certificate within ten (10) days after receipt thereof.

         (d) Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation; provided
that the Borrower shall not be required to compensate a Lender or the Issuing
Bank pursuant to this Section for any increased costs or

                                       30
<PAGE>

reductions incurred more than ninety (90) days prior to the date that such
Lender or the Issuing Bank, as the case may be, notifies the Borrower of the
Change in Law giving rise to such increased costs or reductions and of such
Lender's or the Issuing Bank's intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 90-day period referred to above shall be
extended to include the period of retroactive effect thereof.

         Section 2.17 Break Funding Payments. In the event of (a) the payment of
                      ----------------------
any principal of any LIBOR Rate Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any LIBOR Rate Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any LIBOR Rate Loan on the date specified in any notice delivered
pursuant hereto, or (d) the assignment of any LIBOR Rate Loan other than on the
last day of the Interest Period applicable thereto as a result of a request by
the Borrower pursuant to Section 2.19, then, in any such event, the Borrower
shall compensate each Lender for the loss, cost and expense attributable to such
event. In the case of a LIBOR Rate Loan, such loss, cost or expense to any
Lender shall be deemed to include an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest which would have accrued on the
principal amount of such Loan had such event not occurred, at the LIBOR Rate
that would have been applicable to such Loan, for the period from the date of
such event to the last day of the then current Interest Period therefor (or, in
the case of a failure to borrow, convert or continue, for the period that would
have been the Interest Period for such Loan), over (ii) the amount of interest
which would accrue on such principal amount for such period at the interest rate
which such Lender would bid were it to bid, at the commencement of such period,
for dollar deposits of a comparable amount and period from other banks in the
eurodollar market. A certificate of any Lender setting forth in reasonable
detail any amount or amounts that such Lender is entitled to receive pursuant to
this Section shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay such Lender the amount shown as due on
any such certificate within ten (10) days after receipt thereof.

         Section 2.18 Taxes. (a) Any and all payments by or on account of any
                      -----
obligation of the Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (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) the Administrative Agent, Lender or
Issuing Bank (as the case may be) receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

         (b) In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

         (c) The Borrower shall indemnify the Administrative Agent each Lender
and the Issuing Bank, within ten (10) days after written demand therefor, for
the full amount of any Indemnified

                                       31
<PAGE>

Taxes or Other Taxes paid by the Administrative Agent, such Lender or the
Issuing Bank, as the case may be, on or with respect to any payment by or on
account of any obligation of the Borrower hereunder (including Indemnified Taxes
or Other Taxes imposed or asserted on or attributable to amounts payable under
this Section) and any penalties, interest and removable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the Borrower by a Lender or the Issuing Bank, or by the
Administrative Agent on its own behalf or on behalf of a Lender or the Issuing
Bank, shall be conclusive absent manifest error.

         (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

         (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable
law or reasonably requested by the Borrower as will permit such payments to be
made without withholding or at a reduced rate.

         Section 2.19 Mitigation Obligations; Replacement of Lenders. (a) If any
                      ----------------------------------------------
Lender requests compensation under Section 2.16, or if the Borrower is required
to pay any additional amount to any Lender or any Governmental Authority for the
account of any Lender pursuant to Section 2.17, then such Lender shall use
reasonable efforts to designate a different lending office for funding or
booking its Loans hereunder or to assign its rights and obligations hereunder to
another of its offices, branches or affiliates, if, in the judgment of such
Lender, such designation or assignment (i) would eliminate or reduce amounts
payable pursuant to Section 2.16 or 2.18, as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would
not otherwise be disadvantageous to such Lender.

         (b) If any Lender requests compensation under Section 2.16, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.18,
or if any Lender defaults in its obligation to fund Loans hereunder, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 10.11), all its interests, rights and obligations under this Agreement
to an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent and
the Issuing Bank, which consent shall not unreasonably be withheld, (ii) such
Lender shall have received

                                       32
<PAGE>

payment of an amount equal to the outstanding principal of its Loans and
participations in LC Disbursements, accrued interest thereon, accrued fees and
all other amounts payable to it hereunder, from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts) and (iii) in the case of any such assignment
resulting from a claim for compensation under Section 2.16 or payments required
to be made pursuant to Section 2.18, such assignment will result in a reduction
in such compensation or payments.

                        ARTICLE III - Letters of Credit
                                      -----------------

         Section 3.1 Letters of Credit. Subject to the terms and conditions
                     -----------------
hereof, Borrower may until the Conversion Date request Issuing Bank to issue one
or more Letters of Credit, provided that, after taking such Letter of Credit
into account:

         (a) the sum of the aggregate amount of Revolving Loans outstanding at
such time plus the aggregate amount of LC Obligations at such time, does not
exceed the Borrowing Base at such time;

         (b) the aggregate amount of LC Obligations at such time does not exceed
$20,000,000;

         (c) the expiration date of such Letter of Credit is on or prior to the
Final Maturity Date;

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

         (e) such Letter of Credit is not directly or indirectly used to assure
payment of or otherwise support any Person's Indebtedness for borrowed money;

         (f) the issuance of such Letter of Credit will be in compliance with
all applicable governmental restrictions, policies, and guidelines and will not
subject Issuing Bank to any cost not anticipated on the date hereof;

         (g) the form and terms of such Letter of Credit are acceptable to
Administrative Agent and Issuing Bank in their sole and absolute discretion; and

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

Issuing Bank will honor any such request if the foregoing conditions (a) through
(h) (in this Section 3.1 called the "LC Conditions") have been met as of the
                                     -------------
date of issuance of such Letter of Credit. The expiration date of a Letter of
Credit may not be extended on or after the Conversion Date and no Letter of
Credit may be renewed, replaced or increased on or after the Conversion Date.

         Section 3.2 Requesting Letters of Credit. Borrower must make written
                     ----------------------------
application for any Letter of Credit at least three Business Days before the
date on which Borrower desires for Issuing Bank to issue such Letter of Credit.
By making any such written application Borrower shall

                                       33
<PAGE>

be deemed to have represented and warranted that the LC Conditions described in
Section 3.1 will be met as of the date of issuance of such Letter of Credit.
Each such written application for a standby or commercial Letter of Credit must
be made in writing using the forms therefor customarily used by Issuing Bank,
the terms and provisions of which are hereby incorporated herein by reference
(or in such other form as may mutually be agreed upon by Issuing Bank and
Borrower).

         Section 3.3 Reimbursement and Participations.
                     --------------------------------

         (a) Reimbursement by Borrower. Each Matured LC Obligation shall
             -------------------------
constitute a Loan by Issuing Bank to Borrower. The Borrower hereby agrees to
reimburse the Issuing Bank, forthwith, for each payment or disbursement made by
the Issuing Bank to settle its obligations under any draft drawn under any
Letter of Credit, with interest on the amount so paid or disbursed by the
Issuing Bank from and including the date of payment or disbursement to, but not
including, the date the Issuing Bank is reimbursed therefor or the Lenders are
deemed to have made a Loan in respect thereof pursuant to the following proviso,
as the case may be, at the rate set forth for Base Rate Loans; provided,
however, that (i) if any such payment or disbursement shall not be reimbursed to
the Issuing Bank after any grace period for the payment thereof as provided in
Section 8.1 herein and if the Final Maturity Date shall not have occurred or
(ii) if any Matured LC Obligation shall be outstanding on the Conversion Date,
then the Matured LC Obligation in respect thereof shall automatically, without
notice from or to the Borrower and without any further authorization from the
Borrower (and whether or not the amount thereof satisfies the conditions of
Section 2.1 and whether or not the conditions of Article IV are satisfied), be
deemed to be a Loan, made by each of the Lenders to the Borrower in their
respective Percentage Shares of the Issuing Bank's payments or disbursements
bearing interest determined pursuant to Section 2.6 and the related Matured LC
Obligation shall be deemed paid simultaneously with such funding of the deemed
Loan; provided further, however, that if any such payment or disbursement shall
not be reimbursed to the Issuing Bank and a Loan shall not be deemed to have
been made notwithstanding the preceding proviso for any reason, then the Matured
LC Obligation in respect thereof shall be due and payable, with interest
accruing thereon at the Late Payment Rate.

         (b) Letter of Credit Loans. If the beneficiary of any Letter of Credit
             ----------------------
makes a draft or other demand for payment thereunder prior to the Conversion
Date then Borrower may, during the interval between the making thereof and the
honoring thereof by Issuing Bank, request Lenders to make Revolving Loans to
Borrower in the amount of such draft or demand, which Revolving Loans shall be
made concurrently with Issuing Bank's payment of such draft or demand and shall
be immediately used by Issuing Bank 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 clauses (b) and (c)
of the first sentence of Section 2.1 the amount of such Revolving Loans shall be
considered but the amount of the Matured LC Obligation to be concurrently paid
by such Revolving Loans shall not be considered.

         (c) Participation by Lenders. Issuing Bank irrevocably agrees to grant
             ------------------------
and hereby grants to each Lender, and to induce Issuing Bank to issue Letters of
Credit hereunder, each Lender irrevocably agrees to accept and purchase and
hereby accepts and purchases from Issuing Bank, on

                                       34
<PAGE>

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
Issuing Bank's obligations and rights under each Letter of Credit issued
hereunder and the amount of each Matured LC Obligation paid by Issuing Bank
thereunder. Each Lender unconditionally and irrevocably agrees with Issuing Bank
that, if a Matured LC Obligation is paid under any Letter of Credit for which
Issuing Bank 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 within two (2) Business Days (in all circumstances and without set-off or
counterclaim) pay to Issuing Bank on demand, in immediately available funds at
Issuing Bank'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), together with interest thereon, for each day from the date such
amount was paid by Issuing Bank under such Letter of Credit until the date such
amount is paid to Administrative Agent at the Federal Funds Rate. If any Lender
fails to make such payment to Issuing Bank within such two Business Day period,
such Lender shall in addition to such amount pay interest thereon, for each day
from the date such amount was paid by Issuing Bank under such Letter of Credit
until the date such amount is paid or repaid to Administrative Agent, at the
Base Rate. Each Lender's obligation to pay Issuing Bank pursuant to the terms of
this subsection is irrevocable and unconditional.

         (d) Distributions to Participants. Whenever Issuing Bank has in
             -----------------------------
accordance with this section received from any Lender payment of such Lender's
Percentage Share of any Matured LC Obligation, if Issuing Bank 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 Issuing Bank's
demand that such Lender make such payment of its Percentage Share), Issuing Bank
will distribute to such Lender its Percentage Share of the amounts so received
by Issuing Bank; provided, however, that if any such payment received by Issuing
Bank must thereafter be returned by Issuing Bank, such Lender shall return to
Issuing Bank the portion thereof which Issuing Bank has previously distributed
to it.

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

         Section 3.4 Letter of Credit Fees. In consideration of Issuing Bank's
                     ---------------------
issuance of Letters of Credit, Borrower agrees to pay (i) to the Administrative
Agent for the account of each Lender a participation fee with respect to its
participations in Letters of Credit, which shall accrue at the LIBOR Spread then
in effect with respect to Loans after giving effect thereto on the average daily
amount of such Lender's Percentage Share of the LC Obligations during the period

         Section 3.5 No Duty to Inquire.
                     ------------------

         (a) Drafts and Demands. Issuing Bank 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 of
payment or thereafter. Issuing Bank and Lenders may act in reliance upon any
drafts or demand for payment believed in good faith to have been authorized,
whether or not made by an authorized officer, representative or agent of any
beneficiary under any Letter of Credit, and payment by Issuing Bank to a
beneficiary when requested by any such purported officer, representative or
agent is hereby authorized and approved. Borrower agrees to hold Issuing Bank
and each Lender 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 ISSUING BANK OR ANY LENDER, provided only that Issuing Bank or
such Lender shall not 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 Related Person, or
if the amount of any Letter of Credit is increased at the request of any Related
Person, this Agreement shall be binding upon all Related 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 Issuing Bank or any of Issuing Bank's correspondents 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, Issuing Bank shall have no duty to determine the proper
identity of anyone appearing as transferee of such Letter of Credit, nor shall
Issuing Bank be charged with responsibility of any nature or character for the
validity or correctness of any transfer or successive transfers, and payment by
Issuing Bank to any purported transferee or transferees as determined by Issuing
Bank is hereby authorized and approved, and Borrower further agrees to hold
Issuing Bank and each

                                       36
<PAGE>

Lender 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 ISSUING BANK OR ANY
LENDER, provided only that Issuing Bank or such Lender shall not be entitled to
indemnification for that portion, if any, of any liability or claim which is
caused by its own individual gross negligence or willful misconduct.

         Section 3.6 LC Collateral.
                     -------------

         (a) LC Obligations in Excess of Borrowing Base or upon Termination of
             -----------------------------------------------------------------
Commitments. (i) If, after the making of all mandatory prepayments required
-----------
under Section 2.10, the aggregate amount of all Loans outstanding plus all LC
Obligations outstanding excluding LC Obligations secured by cash collateral
pursuant to Section 3.6 will exceed the Borrowing Base, then Borrower will
immediately pay to Issuing Bank an amount in cash equal to such excess, or (ii)
should any LC Obligations remain outstanding on the Final Maturity Date, then
Borrower will immediately pay Issuing Bank an amount in cash equal to the
aggregate amount of such Issuing Bank's LC Obligations. Issuing Bank will hold
such amount as security for the remaining LC Obligations ("LC Collateral") until
such LC Obligations become Matured LC Obligations, at which time such LC
Collateral may be applied to such Matured LC Obligations. Neither this
subsection nor the following subsection shall, however, limit or impair any
rights which Issuing Bank may have under any other document or agreement
relating to any Letter of Credit or LC Obligation, including any LC Application,
or any rights which Issuing Bank or Lenders may have to otherwise apply any
payments by Borrower and LC Collateral under Section 2.11.

         (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 Issuing Bank 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 Issuing Bank 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 Issuing Bank in such interest-bearing
investments as Issuing Bank may choose in its sole discretion reasonably
exercised. 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, Issuing Bank shall release any remaining
LC Collateral. Borrower hereby assigns and grants to Issuing Bank a continuing
security interest in all LC Collateral paid by it to Issuing Bank, all
investments purchased

                                       37
<PAGE>

with such LC Collateral, and all proceeds thereof to secure its Matured LC
Obligations and its Obligations under this Agreement, the Notes, 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 Mortgage. Borrower
further agrees that Issuing Bank 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.

         proceeding by or before any Governmental Authority or to any remedial
         obligations under Environmental Laws;

         threatened action, investigation or inquiry by any Governmental
         Authority in connection with any Environmental Laws;

             (v)    The Related Persons have taken all steps reasonably

Borrower on a consolidated basis will exceed the amount that the Borrower will
be required to pay (after giving effect to amounts that reasonably could be
received by reason of indemnity, offset, insurance or similar arrangements)

hereby or by any other of the Loan Documents, Indebtedness that will be beyond
its ability to pay as they mature.

         Section 7.6 Production Proceeds. Notwithstanding that, by the terms of
                     -------------------
the various Security Documents, Related Persons are and will be assigning to
Administrative Agent and Lenders all of the "Production Proceeds" (as defined
therein) accruing to the property covered thereby, so long as no Event of
Default has occurred Related 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 an Event of Default, Administrative 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 any Related Person or to receive directly from the purchasers of
production all other Production Proceeds. In no case shall any failure, whether
purposed or inadvertent, by Administrative 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 Administrative Agent or Lenders to any
Related Person constitute a waiver, remission, or release of any other
Production Proceeds or of any rights of Administrative Agent or Lenders to
collect other Production Proceeds thereafter.

which it may have. All rights, remedies and powers conferred upon Administrative
Agent and Lenders 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.

         Section 8.3 Payment of Expenses, Indemnities, etc. The Borrower agrees:
                     -------------------------------------

HAZARDOUS SUBSTANCES ON ANY OF THEIR PROPERTIES, (II) AS A RESULT OF THE BREACH
OR NON-COMPLIANCE BY ANY RELATED PERSON WITH ANY ENVIRONMENTAL LAW APPLICABLE TO
ANY RELATED PERSON, (III) DUE TO PAST OWNERSHIP BY ANY RELATED PERSON OF ANY OF

8.3(C) IN RESPECT OF ANY PROPERTY FOR ANY OCCURRENCE ARISING FROM THE ACTS OR
OMISSIONS OF THE AGENT OR ANY LENDER DURING THE PERIOD AFTER WHICH SUCH PERSON,
ITS SUCCESSORS OR ASSIGNS, OR THEIR AGENTS OR REPRESENTATIVES, SHALL HAVE
OBTAINED POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU OF
FORECLOSURE, AS MORTGAGEE-IN-POSSESSION OR OTHERWISE).

         (d) No Indemnified Party may settle any claim to be indemnified without
the consent of the indemnitor, such consent not to be unreasonably withheld;

claim or demand being made against the Indemnified Party and the Borrower shall
have the non-exclusive right to join in the defense against any such claim or
demand provided that if the Borrower provides a defense, the Indemnified Party
shall bear its own cost of defense unless there is a conflict between the
Borrower and such Indemnified Party.

         (f) THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES
NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER
WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN
OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT
IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE

PARTY IS FOUND TO HAVE COMMITTED AN ACT OF GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT, THIS CONTRACTUAL OBLIGATION OF INDEMNIFICATION SHALL CONTINUE BUT
SHALL ONLY EXTEND TO THE PORTION OF THE CLAIM THAT IS DEEMED TO HAVE

                                       66

                       ARTICLE IX - Administrative Agent
                                    --------------------

         Section 9.1 Appointment and Authority. Each Lender hereby irrevocably
                     -------------------------
authorizes Administrative Agent, and Administrative 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 Administrative Agent by the
terms hereof or thereof, together with all other powers reasonably incidental
thereto. The relationship of Administrative Agent to Lenders is only that of one
commercial bank acting as administrative agent for others, and nothing in the
Loan Documents shall be construed to constitute Administrative Agent a trustee
or other fiduciary for any holder of any of the Notes or of any participation
therein nor to impose on Administrative Agent duties and obligations other than
those expressly provided for in the Loan Documents. 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 Administrative Agent, Administrative
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 Administrative 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 Administrative Agent from Borrower of any
communication calling for action on the part of Lenders or upon notice from any
Lender to Administrative Agent of any Default or Event of Default,
Administrative Agent shall promptly notify each Lender thereof.

         Section 9.2 Exculpation, Administrative Agent's Reliance, Etc. None of
                     -------------------------------------------------
the Administrative Agent, any Arranger or any of the directors, officers,
agents, attorneys, or employees of either, 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, (a) Administrative Agent may treat the payee of any
Note as the holder thereof until Administrative Agent receives written notice of
the assignment or transfer thereof in accordance with this Agreement, signed by
such payee and in form satisfactory to Administrative Agent; (b) each of the
Administrative Agent and each Arranger 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) neither the Administrative Agent nor any Arranger makes any
warranty or representation to any Lender and shall not be responsible to any
Lender for any statements, warranties or representations made in or in
connection with the Loan Documents; (d) neither the Administrative Agent nor any
Arranger shall 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 Related Person, or to inspect the property

                                       67
<PAGE>

(including the books and records) of any Related Person; (e) neither the
Administrative Agent nor any Arranger shall be responsible to any Lender 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 the Related
Persons and the Lenders in exercising its powers hereunder; and (g) neither the
Administrative Agent nor any Arranger shall incur any liability under or in
respect of the Loan Documents by acting upon any notice, consent, certificate or
other instrument or writing (including any telecopy, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper Person or Persons.

         Section 9.3 Lenders' Credit Decisions. Each Lender acknowledges that it
                     -------------------------
has, independently and without reliance upon Administrative Agent, any Arranger
or any other Lender, 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 Lender also acknowledges that it
will independently and without reliance upon Administrative Agent, any Arranger
or any other Lender 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
                     ---------------
Administrative Agent and each Arranger (to the extent not reimbursed by Borrower
within ten (10) days after demand) from and against such Lenders' 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 Administrative Agent or any
Arranger 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 (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 CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR
OMISSION OF ANY KIND BY ADMINISTRATIVE AGENT OR ANY ARRANGER, PROVIDED ONLY THAT
NO LENDER SHALL BE OBLIGATED UNDER THIS SECTION TO INDEMNIFY ADMINISTRATIVE
AGENT OR ANY ARRANGER FOR THAT PORTION, IF ANY, OF ANY LIABILITIES AND COSTS
WHICH IS PROXIMATELY CAUSED BY SUCH PERSON'S OWN INDIVIDUAL GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL JUDGMENT. Cumulative of the
foregoing, each Lender agrees to reimburse Administrative Agent promptly upon
demand for such Lender's Percentage Share of any costs and expenses to be paid
to Administrative Agent by Borrower under Section 6.1(i) to the extent that
Administrative Agent is not timely reimbursed for such expenses by Borrower as
provided in such section. As used in this section the term "Administrative
Agent"

                                       68
<PAGE>

and "Arranger" 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,
                     ----------------
Administrative Agent shall have the same rights and obligations as any Lender
and may exercise such rights as though it were not Administrative Agent. TD, any
successor Administrative Agent, or any of their respective Affiliates may accept
deposits from, lend money to, act as Trustee under indentures of, and generally
engage in any kind of business with any Related Person or their Affiliates,
including without limitation equity investments by TD or any of its Affiliates,
all as if TD were not Administrative Agent hereunder and without any duty to
account therefor to any other Lender.

         Section 9.6 Sharing of Set-Offs and Other Payments. Each of
                     --------------------------------------
Administrative Agent and Lender 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 any Related Person or otherwise, obtain payment of a
portion of the aggregate Obligations owed to it which, taking into account all
distributions made by Administrative Agent under Section 2.11, causes
Administrative Agent or such Lender to have received more than it would have
received had such payment been received by Administrative Agent and distributed
pursuant to Section 2.11, then (a) it shall be deemed to have simultaneously
purchased and shall be obligated to purchase interests in the Obligations as
necessary to cause Administrative Agent and all lenders to share all payments as
provided for in Section 2.11, and (b) such other adjustments shall be made from
time to time as shall be equitable to ensure that Administrative Agent and all
Lenders share all payments of Obligations as provided in Section 2.11; provided,
however, that nothing herein contained shall in any way affect the right of
Administrative Agent or any Lender 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
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 court order to be paid on account of
the possession of such funds prior to such recovery.

         Section 9.7 Investments. Whenever Administrative Agent in good faith
                     -----------
determines that it is uncertain about how to distribute to Lenders any funds
which it has received, or whenever Administrative Agent in good faith determines
that there is any dispute among Lenders about how such funds should be
distributed, Administrative Agent may choose to defer distribution of the funds
which are the subject of such uncertainty or dispute. If Administrative Agent in
good faith believes that the uncertainty or dispute will not be promptly
resolved, or if Administrative Agent is otherwise required to invest funds
pending distribution to Lenders, Administrative 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

                                       69
<PAGE>

investment. All moneys received by Administrative Agent for distribution to
Lenders (other than to the Person which is Administrative Agent in its separate
capacity as a Lender) shall be held by Administrative Agent pending such
distribution solely as Administrative Agent for such Lenders, and Administrative
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
Administrative Agent and Lenders, and no Related Person shall be entitled to
rely on any such provisions or assert any such provision in a claim or defense
against Administrative Agent or any Lender. Administrative Agent and Lenders may

and during the continuance of an Event of Default, at least sixty-six and
two-thirds percent (66 2/3%) of all Directing Lenders' Percentage Shares,
Administrative Agent shall) resign at any time by giving written notice thereof

subject to Borrower's written consent, such consent not to be unreasonably
withheld. A successor must be appointed for any retiring Administrative Agent,
and such Administrative Agent's resignation shall become effective when such
successor accepts such appointment. If, within thirty (30) days after the date
of the retiring Administrative Agent's resignation, no successor Administrative
Agent has been appointed and has accepted such appointment then the refiring
Administrative Agent may appoint a successor Administrative 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 Administrative Agent hereunder by a
successor Administrative Agent, the retiring Administrative Agent shall be
discharged from its duties and obligations under this Agreement and other Loan
Documents. After any retiring Administrative 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 Administrative Agent
under the Loan Documents.

for purposes of the Security Documents and the exercise of such rights and
powers pursuant to the Security Documents as are specifically delegated to TD as
agent thereunder by the terms thereof, together with all other powers reasonably
incidental thereto. The relationship of TD in its capacity as agent for Bank of
Montreal is only that of one commercial bank acting as agent for others, and
nothing herein, in any other Loan Document or in any Security Document shall be
construed to constitute TD in such capacity as a trustee or other fiduciary for
Bank of Montreal. The provisions of this Article IX shall govern the
relationship of TD, in its capacity as agent, and Bank of Montreal, except: (i)
each reference to the

                                       70

"Administrative Agent" shall be deemed to be a reference to TD in its capacity
as agent pursuant to the Security Documents and (ii) for purposes of this
Section 9.10, Bank of Montreal shall have the obligations of a Lender which are
set forth in Sections 9.2 and 9.4 to the extent of its portion of Indebtedness
secured by the Security Documents.

                         -------------------
have any obligations, liabilities, responsibilities or duties under this
Agreement or the other Loan Documents. Without limiting the foregoing, the
Documentation Agent shall not have or be deemed to have any fiduciary
relationship with any Lender or the Administrative Agent. Each Lender
acknowledges that it has not relied, and will not rely, on any of the Lenders so
identified or on the Documentation Agent in deciding to enter into this
Agreement or in taking or not taking action hereunder.

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
Administrative Agent or such Lender 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

required for Administrative Agent, Lenders or any of them to take any particular
action under the Loan Documents, (6) release Borrower from its obligation to pay

          Section 10.2   Survival of Agreements; Cumulative Nature. All of the
                         -----------------------------------------
Related 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 Administrative Agent, Lenders and Issuing Bank and all of
Administrative Agent's, Lenders' and Issuing Bank's obligations to Borrower are
terminated. The rights, powers, and privileges granted to Administrative Agent,
Lenders and Issuing Bank in the Loan Documents, are cumulative, and, except for
expressly specified waivers and consents, no Loan Document shall be construed in
the

                                       72
<PAGE>

context of another to diminish, nullify, or otherwise reduce the benefit to
Administrative Agent, any Lender or Issuing Bank of any such right, power or
privilege.

          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 Administrative Agent may give telephonic notices to Lenders), and shall be
deemed sufficiently given or furnished if delivered by personal delivery, by
telecopy or telex, by delivery service with proof of delivery, or by registered
or certified United States mail, postage prepaid, to Borrower and the other
Related Persons at the address of Borrower specified on the signature pages
hereto and to Administrative Agent, Issuing Bank and the other Lenders at their
addresses specified on the signature pages hereto (unless changed by similar
notice in writing given by the particular Person whose address is to be

(a) in the case of personal delivery or delivery service, as of the date of
first attempted delivery during regular business hours at the address provided
herein, (b) in the case of telecopy of telex, upon receipt, or (c) in the case
of registered or certified United States mail, three (3) days after deposit in
the mail; provided, however, that no Request for Advance or Rate Election shall

          Section 10.4   Parties in Interest. 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 Related Person may assign or transfer any of its rights or
delegate any of its duties or obligations under any Loan Document without the
prior written consent of all 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 Administrative Agent, Issuing Bank and all Lenders, such
purchaser shall not be entitled to any rights of Administrative Agent, Issuing
Bank or Lender under the Loan Documents unless and until Borrower or its
Affiliates have purchased all of the Obligations.

          Section 10.5   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. Borrower hereby irrevocably submits
itself to the non-exclusive jurisdiction of the state and federal courts sitting
in the State of Texas or in the United States District Court for the Southern
District 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. 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
venue thereof is improper and further agrees

                                       73
<PAGE>

to a transfer of any such proceeding to a federal court sitting in the Southern
District for the State of Texas, to the extent that it has subject matter
jurisdiction, and otherwise to a state court in Texas, upon request therefor by
Administrative Agent, if such proceeding is originally brought in another court.

          Section 10.6   Maximum Interest. It is the intention of the parties
                         ----------------
hereto to conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the obligations of each Borrower to each Lender and
the Issuer under this Agreement shall be subject to the limitation that payments
of interest shall not be required to the extent that receipt thereof would be
contrary to provisions of law applicable to such Lender or the Issuer limiting
rates of interest which may be charged or collected by such Lender or the
Issuer. Accordingly, if the transactions contemplated hereby would be usurious
under applicable law (including the Federal and state laws of the United States
of America, or of any other jurisdiction whose laws may be mandatorily
applicable) with respect to a Lender or the Issuer then, in that
event, notwithstanding anything to the contrary in this Agreement, it is agreed
as follows: (i) the provisions of this Section 10.6 shall govern and control;
(ii) the aggregate of all consideration which constitutes interest under
applicable law that is contracted for, charged or received under this Agreement,
or under any of the other aforesaid agreements or otherwise in connection with
this Agreement by such Lender or the Issuer shall under no circumstances exceed
the maximum amount of interest allowed by applicable law (such maximum lawful
interest rate, if any, with respect to such Lender or the Issuer herein called
the "Highest Lawful Rate"), and any excess shall be credited to such Borrower by
     -------------------
such Lender or the Issuer (or, if such consideration shall have been paid in
full, such excess promptly refunded to such Borrower); (iii) all sums paid, or
agreed to be paid, to such Lender or the Issuer for the use, forbearance and
detention of the indebtedness of such Borrower to such Lender or the Issuer
hereunder shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full term of such indebtedness
until payment in full so that the actual rate of interest is uniform throughout
the full term thereof; and (iv) if at any time the interest provided pursuant to
Article II together with any other fees payable pursuant to this Agreement and
deemed interest under applicable law, exceeds that amount which would have
accrued at the Highest Lawful Rate, the amount of interest and any such fees to
accrue to such Lender or the Issuer pursuant to this Agreement shall be limited,
notwithstanding anything to the contrary in this Agreement to that amount which
would have accrued at the Highest Lawful Rate, but any subsequent reductions, as
applicable, shall not reduce the interest to accrue to such Lender or the Issuer
pursuant to this Agreement below the Highest Lawful Rate until the total amount
of interest accrued pursuant to this Agreement and such fees deemed to be
interest equals the amount of interest which would have accrued to such Lender
or the Issuer if a varying rate per annum equal to the interest provided
pursuant to Article II had at all times been in effect, plus the amount of fees
                                                        ----
which would have been received but for the effect of this Section 10.6. For
purposes of Tex. Fin. Code Ann. Ch. 303, as amended, to the extent, if any,
applicable to a Lender or the Issuer, each Borrower agrees that the Highest
Lawful Rate shall be the "weekly ceiling" as defined in said Article, provided
that such Lender and the Issuer may also rely, to the extent permitted by
applicable laws, on alternative maximum rates of interest under other laws
applicable to such Lender or such Issuer, as the case may be, if greater. Tex.
Fin. Code Ann. Ch. 346 (which regulates certain revolving credit loan accounts
and revolving tri-party accounts) shall not apply to this Agreement or the
Notes.

          Section 10.7   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 Administrative Agent to terminate this Agreement.
Upon receipt by Administrative 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 Related Person in any Loan Document any
Obligations under Sections 2.15 through 2.19, and any obligations which any
Person may have to indemnify or compensate Administrative Agent or any Lender
shall survive any termination of this Agreement or any other Loan Document. At
the request and expense of Borrower, Administrative Agent shall prepare and
execute all necessary instruments to reflect and effect such termination of the
Loan Documents. Administrative Agent is hereby authorized to execute all such
instruments on behalf of all Lenders, without the joinder of or further action
by any Lender.

provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable law.

                         ------------
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.

and (iii) any such sale, assignment or transfer shall be pro rata among the
Commitments. The assignee, transferee or recipient shall have, to the extent of
such sale, assignment, or transfer, the same rights, benefits and obligations as
it would if it were such Lender and a holder of such Notes, including, without
limitation, the right to vote on decisions requiring consent or approval of all
Lenders or Majority Lenders and the obligation to fund its Percentage Share of
any Loans and payments made under Letters of Credit. Each Lender in making each
such sale, assignment, or transfer must dispose of a pro rata portion of each
Loan made by such Lender and such Lender's LC Obligations, each such sale,
assignment or transfer shall be in a principal amount not less than $5,000,000
(except assignments to Affiliates of Administrative Agent or any Lender which
may be in an amount equal to or greater than $1,000,000) and no Lender may offer
to sell its Notes and Loans or interests therein in violation of any securities
laws. No such assignment shall become effective until (i) the assigning Lender
delivers to Administrative Agent copies of all written assignments and other
documents evidencing any such assignment or related thereto and an Agreement to
be Bound in the form of Exhibit H, providing for the assignee's ratification and
                        ---------

assignee an assignment fee in the amount of $3,500. Within five (5) Business
Days after its receipt of notice that the Administrative Agent has received
copies of any assignment and the other documents relating thereto, the assignee
shall notify Borrower of the outstanding principal balance of the Notes payable
to such Lender and shall execute and deliver to Administrative Agent (for
delivery to the relevant assignee) new Notes evidencing such assignee's assigned
Loans and, if the assignor Lender has retained a portion of its Loans,
replacement Notes in the principal amount of the Loans retained by the assignor
Lender (such Notes to be in exchange for, but not in payment of, the Notes held
by such Lender). Anything in this Section 10.11 to the contrary notwithstanding,
any Lender may at any time, without the consent of Borrower or Administrative
Agent, assign and pledge all or any portion of its Commitments and the Loans
owing to it to any Federal Reserve Bank (and its transferees) as collateral
security pursuant to Regulation A and any Operating Circular issued by the
Federal Reserve Bank. No such assignment shall release the assigning Lender from
its obligations hereunder.

          (b)  Participations. Each Lender shall have the right to grant
               --------------
participations in all or any part of such Lender's Notes, commitment to make

hereunder on decisions requiring consent or approval of Majority Lenders (except
as set forth in (iii) below) or with respect to determining the Borrowing Base,
(ii) each Lender and Borrower shall be entitled to deal with the Lender granting
a participation in the same manner as if no participation had been granted,
(iii) no participant shall ever have any right by reason of its participation to
exercise any of the rights of Lenders hereunder, except that any Lender may
agree with any participant that such Lender will not, without the consent of
such participant, consent to any amendment or waiver described in Section
10.1(a) requiring

                                       76
<PAGE>

approval of 100% of the Lenders, and (iv) without the Borrower's prior written
consent (not to be unreasonably withheld) no Lender will offer any participation
to any prospective participant if such participant or any affiliates thereof, to
the knowledge of the Lenders selling the participations, is in the energy
industry. Borrower agrees that if amounts outstanding under this Agreement and
the Notes are due or unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each participant
shall be deemed to have the right of set off in respect of its participating
interest in amounts owing under this Agreement and any Note to the same extent
as if the amount of its participating interest were owing directly to it as a
Lender under this Agreement or any Note, provided that such participant shall
only be entitled to such right of set off if it shall have agreed in the
agreement pursuant to which it shall have acquired its participating interest to
share with the Lenders and the proceeds thereof as provided in subsection 9.6.
The Company also agrees that each participant shall be entitled to the benefits
of subsections 2.15, 2.16, 2.18 and 8.3 with respect to its participation in the
Commitments and the Loans outstanding from time to time; provided, that no
participant shall be entitled to receive any greater amount pursuant to such

respect of the amount of the participation transferred by such transferor Lender
to such participant had no such transfer occurred.

permitted if such transfer, assignment or grant would require the Borrower to
file a registration statement with the Securities and Exchange Commission or to
qualify the Loans under the "Blue Sky" laws of any state.

                         ---------------
other Related Person (hereinafter called the "Subject Entities") provides to the
