ITEM 5.  OTHER EVENTS

                  Global Natural Resources Inc. (The "Company") and the
Company's wholly-owned subsidiary, Global Natural Resources Corporation of
Nevada, a Nevada corporation (the "Borrower"), have executed and delivered a
Credit Agreement dated as of May 19, 1995 (the "Credit Agreement") among the
Borrower (as borrower), the Company (as Guarantor), NationsBank of Texas, N.A.,
as Agent, and certain other financial institutions (the "Lenders") which may
become party to the Credit Agreement pursuant to which the Lenders have agreed
to provide loans to the Borrower from time to time, not to exceed in the
aggregate $35,000,000 (subject in all events to certain periodic reductions and
to the calculation of the Available Borrowing Base, as defined in the Credit
Agreement). If the Borrower and the Agent consent and if the Aggregate Maximum
Credit Amounts are changed to exceed $35,000,000, a Lender may assign to a
commercial bank all or part of such Lender's rights under the Credit Agreement.
Subject to the restriction in the Credit Agreement, a Lender may assign
participation in all or part of such Lender's interest in the Credit Agreement.
The Borrower may borrow, repay and re-borrow such amounts available under the
Credit Agreement until March 31, 2000 (subject to certain early termination
dates determined in accordance with the Credit Agreement). In addition,
NationsBank of Texas, N.A., as issuing bank for the Lenders, has agreed to
extend credit to the Borrower (or any subsidiary of the Borrower or of the
company) by issuing, renewing, extending or reissuing letters of credit not
exceeding the lesser of (I) $20,000,000 or (ii) the Aggregate Commitments (as
defined in the Credit Agreement) minus the aggregate principle amount of all
loans then outstanding under the Credit Agreement.

                  The Company has issued a Guaranty Agreement pursuant to which
the Company has guarantied the payment of all indebtedness, obligations and
liabilities under the Credit Agreement.

                  Except for the Guaranty Agreement, the loan facility is
unsecured. The proceeds of the loan facility will be used for general corporate
purposes.

                 Section 2.01     Loans and Letters of Credit.

                 (a) Loans.  Each Lender severally agrees, on the terms of
         this Agreement, to make Loans to the Borrower during the period from
         and including (i) the Closing Date or (ii) such later date that such
         Lender becomes a party to this Agreement as provided in Section
         12.06(b), to and up to, but excluding, the Revolving Credit
         Termination Date in an aggregate principal amount at any one time
         outstanding up to but not exceeding the amount of such Lender's
         Commitment as then in effect; provided, however, that the aggregate
         principal amount of all such Loans by all Lenders hereunder at any one
         time outstanding together with the LC Exposure shall not exceed the
         Aggregate Commitments.  Subject to the terms of this Agreement, during
         the period from the Closing Date to and up to, but excluding, the
         Revolving Credit Termination Date, the Borrower may borrow, repay and
         reborrow the amount described in this Section 2.01(a).

                 (b) Letters of Credit.  During the period from and
         including the Closing Date to but excluding the Revolving Credit
         Termination Date, NationsBank, as issuing bank for the Lenders, agrees
         to extend credit for the account of the Borrower or any Subsidiary at
         any time and from time to time by issuing renewing,  extending or
         reissuing Letters of Credit; provided however, the LC Exposure at any
         one time outstanding shall not exceed the lesser of (i) the LC
         Commitment or (ii) the Aggregate Commitments, as then in effect, minus
         the aggregate principal amount of all Loans then outstanding.  The
         Lenders shall participate in such Letters of Credit according to their
         respective Percentage Shares.

                 (c) Limitation on Types of Loans.  Subject to the other terms
         and provisions of this Agreement, at the option of the Borrower, the
         Loans may be Base Rate Loans or Eurodollar Loans; provided that,
         without the prior written consent of the Majority Lenders, no more
         than five (5) Eurodollar Loans may be outstanding at any time.

                 (a)      Borrowings.  The Borrower shall give the Agent (which
         shall promptly notify the Lenders) advance notice as hereinafter
         provided of each borrowing hereunder, which shall specify the
         aggregate amount of such borrowing, the Type and the date (which shall
         be a Business Day) of the Loans to be borrowed and (in the case of
         Eurodollar Loans) the duration of the Interest Period therefor.

                 (b)      Minimum Amounts.  All Base Rate Loan borrowings shall
         be in amounts of at least $100,000 or the remaining balance of the
         Aggregate Commitments, if less, or any whole multiple of $100,000  in
         excess thereof, and all Eurodollar Loans shall be in amounts of at
         least $500,000 or any whole multiple of $500,000 in excess thereof.

                 (c)      Notices.  All borrowings, continuations and
         conversions shall require advance written notice to the Agent (which
         shall promptly notify the Lenders) in the form of Exhibit B hereto (or
         telephonic notice promptly confirmed by such a written notice), which
         in each case shall be irrevocable, from the Borrower to be received by
         the Agent not later than 11:00 a.m. Houston, Texas time on the date of
         each Base Rate Loan borrowing and three Business Days prior to the
         date of each Eurodollar Loan borrowing, continuation or conversion.
         Without in any way limiting the Borrower's obligation to confirm in
         writing any telephonic notice, the Agent may act without liability
         upon the basis of telephonic notice believed by the Agent in good
         faith to be from the Borrower prior to receipt of written
         confirmation.  In each such case, the Borrower hereby waives the right
         to dispute the Agent's record of the terms of such telephonic notice
         except in the case of gross negligence or willful misconduct by the
         Agent.

                 (d)      Continuation Options.  Subject to the provisions made
         in this Section 2.02(d), the Borrower may elect to continue all or any
         part of any Eurodollar Loan beyond the expiration of the then current
         Interest Period relating thereto by giving advance notice as provided
         in Section 2.02(c) to the Agent (which shall promptly notify the
         Lenders) of such election, specifying the amount of such Loan to be
         continued and the Interest Period therefor.  In the absence of such a
         timely and proper election, the Borrower shall be deemed to have
         elected to convert such Eurodollar Loan to a Base Rate Loan pursuant
         to Section 2.02(e).  All or any part of any Eurodollar Loan may be
         continued as provided herein, provided that (i) any continuation of
         any such Loan shall be (as to each Loan as continued for an applicable
         Interest Period) in amounts of at least $500,000 or any whole multiple
         of $500,000 in excess thereof and (ii) no Default shall have occurred
         and be continuing.  If a Default shall have occurred and be
         continuing, each Eurodollar Loan shall be converted to a Base Rate
         Loan on the last day of the Interest Period applicable thereto.

                 (e) Conversion Options.  The Borrower may elect to
         convert all or any part of any Eurodollar Loan on the last day of the
         then current Interest Period relating thereto to a Base Rate Loan by
         giving advance notice to the Agent (which shall promptly notify the
         Lenders) of such election.  Subject to the provisions made in this
         Section 2.02(e), the Borrower may elect to convert all or any part of
         any Base Rate Loan at any time and from time to time to a Eurodollar
         Loan by giving advance notice as provided in Section 2.02(c) to the
         Agent (which shall promptly notify the Lenders) of such election.  All
         or any part of any outstanding Loan may be converted as provided
         herein, provided that (i) any conversion of any Base Rate Loan into a
         Eurodollar Loan shall be (as to each such Loan into which there is a
         conversion for an applicable Interest Period) in amounts of at least
         $500,000 or any whole multiple of $500,000 in excess thereof and (ii)
         no Default shall have occurred and be continuing.  If a Default shall
         have occurred and be continuing, no Base Rate Loan may be converted
         into a Eurodollar Loan.

                 (f) Advances.  Not later than 11:00 a.m. Houston, Texas time
         on the date specified for each borrowing hereunder, each Lender shall
         make available the amount of the Loan to be made by it on such date to
         the Agent, to an account which the Agent shall specify, in immediately
         available funds, for the account of the Borrower.  The amounts so
         received by the Agent shall, subject to the terms and conditions of
         this Agreement, be made available to the Borrower by depositing the
         same, in immediately available funds, in an account of the Borrower,
         designated by the Borrower and maintained at the Principal Office.

                 (g) Letters of Credit.  The Borrower shall give the Agent
         (which shall promptly notify the Lenders of such request and their
         Percentage Share of such Letter of Credit) advance notice to be
         received by the Agent not later than 11:00 a.m.  Houston, Texas time
         not less than three (3) Business Days prior thereto of each request
         for the issuance and at least thirty (30) days prior to the date of
         the renewal or extension of a Letter of Credit hereunder which request
         shall specify the amount of such Letter of Credit, the date (which
         shall be a Business Day) such Letter of Credit is to be issued,
         renewed or extended, the duration thereof, the name and address of the
         beneficiary thereof, the form of the Letter of Credit and such other
         information as the Agent may reasonably request all of which shall be
         reasonably satisfactory to the Agent.  Subject to the terms and
         conditions of this Agreement, on the date specified for the issuance,
         renewal or extension of a Letter of Credit, NationsBank shall issue
         such Letter of Credit to the beneficiary thereof.

                 In conjunction with the issuance of each Letter of Credit, the
         Borrower and the Subsidiary, if the account party, shall execute a
         Letter of Credit Agreement.  In the event of any conflict between any
         provision of a Letter of Credit Agreement and this Agreement, the
         Borrower, the Agent and the Lenders hereby agree that the provisions
         of this Agreement shall govern.

         Date.

                 (c)      The Borrower shall have the right to terminate or to

         or from time to time upon not less than three (3) Business Days' prior
         notice to the Agent (which shall promptly notify the Lenders) of each

         effective date thereof and the amount of any such reduction (which
         shall not be less than $1,000,000 or any whole multiple of $1,000,000
         in excess thereof) and shall be irrevocable and effective only upon

         minus the Loans and the LC Exposure) for the period from and including
         the Effective Date up to but excluding the earlier of the date the
         Aggregate Maximum Credit Amounts are terminated or the Revolving
         Credit Termination Date at a rate per annum equal to 3/8 of 1%.

         in advance at issuance of each Letter of Credit and, if any such Letter
         of Credit extends beyond one (1) year, annually in advance on each
         annual anniversary thereof.

                 (c)      The Borrower shall pay to the Agent for its account
         such other fees as are set forth in the Fee Letter on the dates
         specified therein to the extent not paid prior to the Closing Date.

                 Section 2.05     Several Obligations.  The failure of any
Lender to make any Loan to be made by it or to provide funds for disbursements
or reimbursements under Letters of Credit on the date specified therefor shall
not relieve any other Lender of its obligation to make its Loan or provide
funds on such date, but no Lender shall be responsible for the failure of any
other Lender to make a Loan to be made by such other Lender or to provide funds
to be provided by such other Lender.  Notwithstanding the foregoing with
respect to obligations to make Loans, NationsBank, as issuer of the Letter of
Credit, shall be obligated to duly honor any proper drawing thereunder.

                 Section 2.06     Notes.  The Loans made by each Lender shall
be evidenced by a single promissory note of the Borrower in substantially the
form of Exhibit A hereto, dated (i) the Closing Date or (ii) the effective date
of an Assignment pursuant to Section 12.06(b), payable to the order of such
Lender in a principal amount equal to its Maximum Credit Amount as originally
in effect and otherwise duly completed.  The date, amount, Type, interest rate
and Interest Period of each Loan made by each Lender, and all payments made on
account of the principal thereof, shall be recorded by such Lender on its books
for its Note, and, prior to any transfer, endorsed by such Lender on the
schedule attached to such Note or any continuation thereof.  Such records shall
be deemed conclusive absent manifest error; provided that any failure to make
notation of any repayment of principal shall not cancel, limit or otherwise
affect the Borrower's entitlement to credit for that payment as of the date
received by the Agent.

                 Section 2.07     Prepayments.

                 (a)      The Borrower may prepay (i) the Base Rate Loans
         without notice and (ii) the Eurodollar Loans upon not less than three
         (3) Business Days' prior notice to the Agent (which shall promptly
         notify the Lenders), which notice shall specify the prepayment date
         (which shall be a Business Day) and the amount of the prepayment
         (which shall be at least $500,000 or the remaining aggregate principal
         balance outstanding on the Notes) and shall be irrevocable and
         effective only upon receipt

by the Agent, provided that interest on the principal prepaid, accrued to the
prepayment date, shall be paid on the prepayment date.  In addition, such
prepayments of Eurodollar Loans shall be subject to the terms of Section 5.05
and shall be in an amount equal to all of the Eurodollar Loans for the Interest
Period prepaid.

                 (b)      If, after giving effect to any termination or
         reduction of the Aggregate Maximum Credit Amounts pursuant to Section
         2.03(b) or (c), the outstanding aggregate principal amount of the
         Loans plus the LC Exposure exceeds the Aggregate Maximum Credit
         Amounts, the Borrower shall (i) prepay the Loans on the date of such
         termination or reduction in an aggregate principal amount equal to the
         excess, together with interest on the principal amount paid accrued to
         the date of such prepayment and (ii) if any excess remains after
         prepaying all of the Loans, pay to the Agent on behalf of the Lenders
         an amount equal to the excess (a "Deficiency") to be held as cash
         collateral as provided in Section 2.10(b) hereof.

                 (c)      Upon any redetermination of the amount of the
         Borrowing Base in accordance with Section 2.08, if the redetermined
         Borrowing Base is less than the Total Debt, then the Borrower shall,
         upon receipt of written notice thereof, do one or a combination of the
         following:  (i) within ten (10) days prepay the outstanding principal
         balance of the Loans by the amount of such deficiency, together with
         interest on the principal amount paid accrued to the date of such
         prepayment, (ii) prepay the outstanding principal balance of the Loans
         by the amount of such deficiency in monthly installments in amounts
         and over a period of months to be determined by the Agent, but in any
         event within a period of no more than six (6) months of receipt of
         such notice or (iii) within thirty (30) days of receipt of such
         written notice, provide collateral satisfactory to the Agent and the
         Lenders under Security Instruments which are reasonably satisfactory
         in form and substance to the Agent, which collateral has not
         previously been included in the Borrowing Base.  If a Borrowing Base
         deficiency remains after prepaying all of the Loans because of LC
         Exposure, the Borrower shall pay to the Agent on behalf of the Lenders
         an amount equal to such Borrowing Base deficiency (a "Deficiency") to
         be held as cash collateral as provided in Section 2.10(b) hereof.

                 (d)      Prepayments permitted or required under this Section
         2.07 shall be without premium or penalty, except as required under
         Section 5.05 for prepayment of Eurodollar Loans and Borrower may
         select, if a choice is available, which Loans (Base Rate Loans or
         Eurodollar Rate Loans) to so prepay.

                 Section 2.08     Borrowing Base.

                 (a)      During the period from and after the Closing Date
         until the Borrowing Base is redetermined pursuant to this Section
         2.08, the amount of the Borrowing Base

         shall be $35,000,000.  The Borrowing Base and all redeterminations
         thereof shall be determined in accordance with Section 2.08(b) by the
         Agent with the concurrence of the Majority Lenders and is subject to
         redetermination in accordance with Section 2.08(d).  Upon any
         redetermination of the Borrowing Base, such redetermination shall
         remain in effect until the next successive Redetermination Date.
         "Redetermination Date" shall mean the date that the redetermined
         Borrowing Base becomes effective subject to the notice requirements
         specified in Section 2.08(e) both for scheduled redeterminations and
         unscheduled redeterminations.  So long as any of the Commitments are
         in effect or any LC Exposure or Loans are outstanding hereunder, this
         facility shall be governed by the then effective Borrowing Base.

                 (b)      Upon receipt of the reports required by Section 8.07
         and such other reports, data and supplemental information as may from
         time to time be reasonably requested by the Agent, the Agent will
         redetermine the Borrowing Base unless otherwise provided in Section
         2.08(d) below.  Such redetermination will be in accordance with its
         normal and customary procedures for evaluating oil and gas reserves
         and other related assets as such exist at that particular time.  The
         Agent, in its sole discretion, shall consider Oil and Gas Properties
         and revenues therefrom located in the United States and Indonesia, and
         may make adjustments to the rates, volumes and prices and other
         assumptions set forth therein in accordance with its normal and
         customary procedures for evaluating oil and gas reserves and other
         related assets as such exist at that particular time.  The Agent shall
         propose to the Lenders a new Borrowing Base within 15 days following
         receipt by the Agent and the Lenders of the Reserve Reports in a
         timely and complete manner.  After having received notice of such
         proposal by the Agent, the Majority Lenders shall have 10 days to
         agree or disagree with such proposal.  If at the end of the 10 days,
         the Majority Lenders have not communicated their approval or
         disapproval, such silence shall be deemed to be an approval and the
         Agent's proposal shall be the new Borrowing Base.  If however, the
         Majority Lenders notify Agent within 10 days of their disapproval, the
         Majority Lenders shall, within a reasonable period of time, agree on a
         new Borrowing Base.  Until the Majority Lenders have agreed to a new
         Borrowing Base, as aforesaid, the then existing Borrowing Base shall
         continue.

                 (c)      The Agent may exclude any Oil and Gas Property or
         portion of production therefrom or any income from any other Property
         from the Borrowing Base, at any time, because the title status or
         information is not reasonably satisfactory; provided, however, so long
         as there is no known claim against the status of title to the revenues
         from the Oil and Gas Properties located in Indonesia, such title
         status and information shall be deemed satisfactory.

                 (d)      So long as any of the Commitments are in effect and
         until payment in full of all Loans hereunder and termination of all LC
         Exposure, on or around the last

         Business Day of each April and October, commencing October 31, 1995
         (each being a "Scheduled Redetermination Date"), the Lenders shall
         redetermine the amount of the Borrowing Base and the corresponding
         quarterly reductions thereto in accordance with Section 2.08(b).  The
         October Scheduled Redetermination Date shall be waived in the event
         that no Loans or Letters of Credit have been outstanding at any time
         during the six (6) month period ending on October 31 of any year.  In
         addition, the Majority Lenders may initiate a redetermination of the
         Borrowing Base when (i) the aggregate outstanding principal amount of
         the Loans plus the LC Exposure is greater than or equal to 50% of the
         Available Borrowing Base or (ii) the Agent has received notification
         of a sale pursuant to Section 9.14(iv).

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

                 Section 2.09     Assumption of Risks.  The Borrower assumes
all risks of the acts or omissions of any beneficiary of any Letter of Credit
or any transferee thereof with respect to its use of such Letter of Credit.
NationsBank shall examine documents with the same care it exercises for all
letters of credit issued by it so as to ascertain that on their face they
appear to comply with the terms of the Letter of Credit, but neither
NationsBank (except in the case of gross negligence, willful misconduct or bad
faith on the part of NationsBank or any of its employees), its correspondents
nor any Lender shall be responsible for the validity, sufficiency or
genuineness of certificates or other documents or any endorsements thereon,
even if such certificates or other documents should in fact prove to be
invalid, insufficient, fraudulent or forged; for errors, omissions,
interruptions or delays in transmissions or delivery of any messages by mail,
telex, or otherwise, whether or not they be in code; for errors in translation
or for errors in interpretation of technical terms; the validity or sufficiency
of any instrument transferring or assigning or purporting to transfer or assign
any Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, which may prove to be invalid or ineffective for any
reason; or for any other consequences arising from causes beyond NationsBank's
control or the control of NationsBank's correspondents.  In addition, neither
NationsBank nor any Lender shall be responsible for any error, neglect, or
default of any of NationsBank's correspondents; and none of the above shall
affect, impair or prevent the vesting of any of NationsBank's or any Lender's
rights or powers hereunder or under the Letter of Credit Agreements, all of
which rights shall be cumulative.  NationsBank and its correspondents may
accept certificates or other documents that appear on their face to be in
order, without responsibility for further investigation of any matter contained
therein regardless of any notice or information to the contrary.  In
furtherance and not in limitation of the foregoing provisions, the Borrower
agrees that any action, inaction or omission taken or not taken by NationsBank
or by any correspondent for NationsBank in good faith in connection with any
Letter of Credit, or any related drafts, certificates, documents or
instruments, shall be binding on the Borrower and

shall not put NationsBank or its correspondents under any resulting liability
to the Borrower.

                 Section 2.10     Obligation to Reimburse and to Prepay.

                 (a)      If a disbursement by NationsBank is made under any
         Letter of Credit, the Borrower shall pay to the Agent within two (2)
         Business Days after notice of any such disbursement is received by the
         Borrower, the amount of each such disbursement made by NationsBank
         under the Letter of Credit (if such payment is not sooner effected as
         may be required under this Section 2.10 or under other provisions of
         the Letter of Credit), together with interest on the amount disbursed
         from and including the date of disbursement until payment in full of
         such disbursed amount at a varying rate per annum equal to (i) the
         then applicable interest rate for Base Rate Loans through the second
         Business Day after notice of such disbursement is received by the
         Borrower and (ii) thereafter, the Post-Default Rate for Base Rate
         Loans (but in no event to exceed the Highest Lawful Rate) for the
         period from and including the third Business Day following the date of
         such disbursement to and including the date of repayment in full of
         such disbursed amount.  The obligations of the Borrower under this
         Agreement with respect to each Letter of Credit shall be absolute,
         unconditional and irrevocable and shall be paid or performed strictly
         in accordance with the terms of this Agreement under all circumstances
         whatsoever, including, without limitation, but only to the fullest
         extent permitted by applicable law, the following circumstances: (i)
         any lack of validity or enforceability of this Agreement, any Letter
         of Credit or any of the Security Instruments; (ii) the existence of
         any claim, set-off, defense or other rights which the Borrower may
         have at any time against the beneficiary of any Letter of Credit or
         any transferee of any Letter of Credit (or any Persons for whom any
         such beneficiary or any such transferee may be acting), the Agent, any
         Lender or any other Person, whether in connection with this Agreement,
         any Letter of Credit, the Security Instruments, the transactions
         contemplated hereby or an unrelated transaction, (iii) any statement,
         certificate, draft, notice or any other document presented under any
         Letter of Credit proves to have been forged, fraudulent, insufficient
         or invalid in any respect or any statement therein proves to have been
         untrue or inaccurate in any respect whatsoever, but in each case only
         if the same appear on their face to conform to the terms of the Letter
         of Credit; and (iv) payment by the Agent under any Letter of Credit
         against presentation of a draft or certificate which appears on its
         face to comply, but does not comply, with the terms of such Letter of
         Credit.

         Notwithstanding anything in this Agreement to the contrary, the
         Borrower will not be liable for payment or performance that results
         from the gross negligence or willful misconduct of the Agent, except
         where the Borrower or any Subsidiary actually recovers the proceeds
         for itself or the Agent of any payment made by the Agent in connection
         with such gross negligence or willful misconduct.

                 (b)      In the event of the occurrence of any Event of
         Default, a payment or prepayment requirement pursuant to Sections
         2.07(b) and (c) hereof or the maturity of the Notes, whether by
         acceleration or otherwise, an amount equal to the LC Exposure (or in
         the case of a prepayment requirement under Section 2.07(b) or (c), an
         amount equal to the Deficiency) shall be deemed to be forthwith due
         and owing by the Borrower to the Agent and the Lenders as of the date
         of any such occurrence; and the Borrower's obligation to pay such
         amount shall be absolute and unconditional, without regard to whether
         any beneficiary of any such Letter of Credit has attempted to draw
         down all or a portion of such amount under the terms of a Letter of
         Credit, and, to the fullest extent permitted by applicable law, shall
         not be subject to any defense or be affected by a right of set-off,
         counterclaim or recoupment which the Borrower may now or hereafter
         have against any such beneficiary, the Agent, the Lenders or any other
         Person for any reason whatsoever.  Such payments shall be held by the
         Agent on behalf of the Lenders as cash collateral securing the
         obligations of the Borrower with respect to Letters of Credit in an
         interest-bearing account or accounts at the Principal Office; and the
         Borrower hereby grants to and by its deposit with the Agent grants to
         the Agent a security interest in such cash collateral.  In the event
         of any such payment by the Borrower of amounts contingently owing
         under outstanding Letters of Credit and in the event that thereafter
         (i) drafts or other demands for payment complying with the terms of
         such Letters of Credit are not made prior to the respective expiration
         dates thereof, or (ii) the amount on hold hereunder exceeds the
         Deficiency, the Agent agrees, if no Default has occurred and is
         continuing, to remit to the Borrower amounts for which the contingent
         obligations evidenced by the Letters of Credit have ceased and/or the
         amount of the excess over the Deficiency.

                 (c)      Each Lender severally and unconditionally agrees that
         it shall promptly reimburse the Agent an amount equal to such Lender's
         Percentage Share of any disbursement made by the Agent under any
         Letter of Credit that is not reimbursed according to this Section
         2.10.

                 Section 2.11     Lending Offices.  The Loans of each Type made
by each Lender shall be made and maintained at such Lender's Applicable Lending
Office for Loans of such Type.

Section 3.01.  On the Revolving Credit Termination Date the Borrower shall
repay the outstanding aggregate principal and accrued and unpaid interest under
the Notes.

                 Section 3.02     Interest.  The Borrower will pay to the
Agent, for account of each Lender, interest on the unpaid principal amount of
each Loan made by such Lender for the period commencing on the date such Loan
is made to but excluding the date such Loan shall be paid in full, at the
following rates per annum:

                 (i)      if such a Loan is a Base Rate Loan, the Base Rate (as
         in effect from time to time) plus the Applicable Margin, but in no
         event to exceed the Highest Lawful Rate; and

                 (ii)     if such a Loan is a Eurodollar Loan, for each
         Interest Period relating thereto, the Fixed Rate for such Loan plus
         the Applicable Margin, but in no event to exceed the Highest Lawful
         Rate.

Notwithstanding the foregoing, the Borrower will pay to the Agent, for the
account of each Lender interest at the applicable Post-Default Rate on any
principal of any Loan made by such Lender, and (to the fullest extent permitted
by law) on any other amount payable by the Borrower hereunder, under any
Security Instrument or under any Note held by such Lender to or for account of
such Lender, which shall not be paid in full when due (whether at stated
maturity, by acceleration or otherwise), for the period commencing on the due
date thereof until the same is paid in full.

         Accrued interest on Base Rate Loans shall be payable on each Quarterly
Date commencing on June 30, 1995 and accrued interest on each Eurodollar Loan
shall be payable on the last day of the Interest Period therefor and, if such
Interest Period is longer than three months at three-month intervals following
the first day of such Interest Period, except that interest payable at the
Post-Default Rate shall be payable from time to time on demand and interest on
any Eurodollar Loan that is converted into a Base Rate Loan (pursuant to
Section 5.04) shall be payable on the date of conversion (but only to the
extent so converted).

         Promptly after the determination of any interest rate provided for
herein or any change therein, the Agent shall notify the Lenders to which such
interest is payable and the Borrower thereof.  Each determination by the Agent
of an interest rate or fee hereunder shall, except in cases of manifest error,
be final, conclusive and binding on the parties.

                 Section 4.01     Payments.  Except to the extent otherwise
provided herein, all payments of principal, interest and other amounts to be
made by the Borrower under this Agreement, the Notes and the Letter of Credit
Agreements shall be made in Dollars, in immediately available funds, to the
Agent at such account as the Agent shall specify by notice to the Borrower from
time to time, not later than 11:00 a.m. Houston, Texas time on the date on
which such payments shall become due (each such payment made after such time on
such due date to be deemed to have been made on the next succeeding Business
Day, to the extent permitted by applicable law).  Each payment received by the
Agent under this Agreement or any Note for account of a Lender shall be paid
promptly to such Lender in immediately available funds.  If the due date of any
payment under this Agreement or any Note would otherwise fall on a day which is
not a Business Day such date shall be extended to the next succeeding Business
Day and interest shall be payable for any principal so extended for the period
of such extension at the pre-default rate applicable thereto.  At the time of
each payment to the Agent of any principal of or interest on any borrowing, the
Borrower shall notify the Agent of the Loans to which such payment shall apply.
In the absence of such notice the Agent may specify the Loans to which such
payment shall apply, but to the extent possible such payment or prepayment will
be applied first to the Loans comprised of Base Rate Loans.

                 Section 4.02     Pro Rata Treatment.  Except to the extent
otherwise provided herein each Lender agrees that: (i) each borrowing from the
Lenders under Section 2.01 shall be made from the Lenders pro rata in
accordance with their Percentage Share, each payment of commitment fee or other
fees under Section 2.04(a) or (b) be made for account of the Lenders pro rata
in accordance with their Percentage Share, and each termination or reduction of
the amount of the Aggregate Maximum Credit Amounts under Section 2.03(b) or (c)
shall be applied to the Commitment of each Lender, pro rata according to the
amounts of its respective Commitment; (ii) each payment of principal of Loans
by the Borrower shall be made for account of the Lenders pro rata in accordance
with the respective unpaid principal amount of the Loans held by the Lenders;
and (iii) each payment of interest on Loans by the Borrower shall be made for
account of the Lenders pro rata in accordance with the amounts of interest due
and payable to the respective Lenders; and (iv) each reimbursement by the
Borrower of disbursements under Letters of Credit shall be made for account of
the Agent or, if funded by the Lenders, pro rata for the account of the
Lenders, in accordance with the amounts of reimbursement obligations due and
payable to each respective Lender; provided, however, if a Lender has failed to
make a Loan or to pay its share of any LC Exposure as and when required
hereunder and there is subsequently a repayment on the Loans or LC Exposure,
such repayment shall be split among the non-defaulting Lenders ratably in
accordance with their respective percentages until each Lender has its correct
Percentage Share of all outstanding Loans and LC Exposure, and the

balance of such repayment shall be divided among all of the Lenders in
accordance with their respective Percentage Shares.

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

                 Section 4.04     Set-off, Sharing of Payments, Etc.

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

                 (b)      If any Lender shall obtain payment of any principal
         of or interest on any Loan made by it to the Borrower under this
         Agreement through the exercise of any right of set-off, banker's lien
         or counterclaim or similar right or otherwise, and, as a result of
         such payment, such Lender shall have received a greater percentage of
         the principal or interest then due hereunder by the Borrower to such
         Lender than the percentage received by any other Lenders, it shall
         promptly (i) notify the Agent and each other Lender thereof and (ii)
         purchase from such other Lenders participations in (or, if and to the
         extent specified by such Lender, direct interests in) the Loans made
         by such other Lenders (or in interest due thereon, as the case may be)
         in such amounts, and make such other adjustments from time to time as
         shall be equitable, to the end that all the Lenders shall share the
         benefit of such excess payment (net of any expenses which may be
         incurred by such Lender in obtaining or preserving such excess
         payment) pro rata in accordance with the unpaid principal and/or
         interest on the Loans held by each of the Lenders.  To such end all
         the Lenders shall make appropriate adjustments among themselves (by
         the resale of participations sold or otherwise) if such payment is
         rescinded or must otherwise be restored.  The Borrower agrees that any
         Lender so purchasing a participation (or direct interest) in the Loans
         made by other Lenders (or in interest due thereon, as the case may be)
         may exercise all rights of set-off, banker's lien, counter

         claim or similar rights with respect to such participation as fully as
         if such Lender were a direct holder of Loans in the amount of such
         participation.  Nothing contained herein shall require any Lender to
         exercise any such right or shall affect the right of any Lender to
         exercise, and retain the benefits of exercising, any such right with
         respect to any other indebtedness or obligation of the Borrower.  If
         under any applicable bankruptcy, insolvency or other similar law, any
         Lender receives a secured claim in lieu of a set-off to which this
         Section 4.04 applies, such Lender shall, to the extent practicable,
         exercise its rights in respect of such secured claim in a manner
         consistent with the rights of the Lenders entitled under this Section
         4.04 to share the benefits of any recovery on such secured claim.

                 Section 4.05     Taxes.

                 (a)      Payments Free and Clear.  Any and all payments by the
         Borrower hereunder shall be made, in accordance with Section 4.01,
         free and clear of and without deduction for any and all present or
         future taxes, levies, imposts, deductions, charges or withholdings,
         and all liabilities with respect thereto, excluding, in the case of
         each Lender and the Agent, taxes imposed on its income, and franchise
         or similar taxes imposed on it, by (i) any jurisdiction (or political
         subdivision thereof) of which the Agent or such Lender, as the case
         may be, is a citizen or resident or in which such Lender has an
         Applicable Lending Office, (ii) the jurisdiction (or any political
         subdivision thereof) in which the Agent or such Lender is organized,
         or (iii) any jurisdiction (or political subdivision thereof) in which
         such Lender or the Agent is presently doing business which taxes are
         imposed solely as a result of doing business in such jurisdiction (all
         such non- excluded taxes, levies, imposts, deductions, charges,
         withholdings and liabilities being hereinafter referred to as
         "Taxes").  If the Borrower shall be required by law to deduct any
         Taxes from or in respect of any sum payable hereunder to the Lenders
         or the Agent (i) the sum payable shall be increased by the amount
         necessary so that after making all required deductions (including
         deductions applicable to additional sums payable under this Section
         4.05) such Lender or the Agent (as the case may be) shall receive 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 taxing
         authority or other Governmental Authority in accordance with
         applicable law.

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

                 (c)      INDEMNIFICATION.  TO THE FULLEST EXTENT PERMITTED BY
         APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE AGENT
         FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT
         LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL
         AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.05) PAID BY SUCH
         LENDER OR THE AGENT (ON THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS
         THE CASE MAY BE, AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND
         EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT
         SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED UNLESS
         THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED AND
         SUCH LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF
         ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  ANY PAYMENT PURSUANT TO
         SUCH INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS AFTER THE
         DATE ANY LENDER OR THE AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND
         THEREFOR.  IF ANY LENDER OR THE AGENT RECEIVES A REFUND OR CREDIT IN
         RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER OR THE AGENT
         HAS RECEIVED PAYMENT FROM THE BORROWER IT SHALL PROMPTLY NOTIFY THE
         BORROWER OF SUCH REFUND OR CREDIT AND SHALL, IF NO DEFAULT HAS
         OCCURRED AND IS CONTINUING, WITHIN THIRTY (30) DAYS AFTER RECEIPT OF A
         REQUEST BY THE BORROWER (OR PROMPTLY UPON RECEIPT, IF THE BORROWER HAS
         REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY
         AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE BORROWER WITHOUT
         INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED), PROVIDED
         THAT THE BORROWER, UPON THE REQUEST OF SUCH LENDER OR THE AGENT,
         AGREES TO RETURN SUCH REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR
         OTHER CHARGES) TO SUCH LENDER OR THE AGENT IN THE EVENT SUCH LENDER OR
         THE AGENT IS REQUIRED TO REPAY SUCH REFUND OR CREDIT.


                 (d)      Lender Representations.

                          (i)     Each Lender represents that it is either (a)
                 a corporation organized under the laws of the United States of
                 America or any state thereof or (b) it is entitled to complete
                 exemption from United States withholding tax imposed on or
                 with respect to any payments, including fees, to be made to it
                 pursuant to this Agreement (A) under an applicable provision
                 of a tax convention to which the United States of America is a
                 party or (B) because it is acting through a branch, agency or
                 office in the United States of America and any payment to be
                 received by it hereunder is effectively connected with a trade
                 or business in the United States of America.  Each Lender that
                 is not a corporation organized under the laws of the United
                 States of America or any state thereof agrees to provide to
                 the Borrower and the Agent on the Closing Date, or on the date
                 of its delivery of the Assignment pursuant to which it becomes
                 a Lender, and at such other times as required by United States
                 law or as the Borrower or the Agent shall reasonably

                 request, two accurate and complete original signed copies of
                 either (A) Internal Revenue Service Form 4224 (or successor
                 form) certifying that all payments to be made to it hereunder
                 will be effectively connected to a United States trade or
                 business (the "Form 4224 Certification") or (B) Internal
                 Revenue Service Form 1001 (or successor form) certifying that
                 it is entitled to the benefit of a provision of a tax
                 convention to which the United States of America is a party
                 which completely exempts from United States withholding tax
                 all payments to be made to it hereunder (the "Form 1001
                 Certification").  In addition, each Lender agrees that if it
                 previously filed a Form 4224 Certification, it will deliver to
                 the Borrower and the Agent a new Form 4224 Certification prior
                 to the first payment date occurring in each of its subsequent
                 taxable years; and if it previously filed a Form 1001
                 Certification, it will deliver to the Borrower and the Agent a
                 new certification prior to the first payment date falling in
                 the third year following the previous filing of such
                 certification.  Each Lender also agrees to deliver to the
                 Borrower and the Agent such other or supplemental forms as may
                 at any time be required as a result of changes in applicable
                 law or regulation in order to confirm or maintain in effect
                 its entitlement to exemption from United States withholding
                 tax on any payments hereunder, provided that the circumstances
                 of such Lender at the relevant time and applicable laws permit
                 it to do so.  If a Lender determines, as a result of any
                 change in either (i) a Governmental Requirement or (ii) its
                 circumstances, that it is unable to submit any form or
                 certificate that it is obligated to submit pursuant to this
                 Section 4.05, or that it is required to withdraw or cancel any
                 such form or certificate previously submitted, it shall
                 promptly notify the Borrower and the Agent of such fact.  If a
                 Lender is organized under the laws of a jurisdiction outside
                 the United States of America, unless the Borrower and the
                 Agent have received a Form 1001 Certification or Form 4224
                 Certification satisfactory to them indicating that all
                 payments to be made to such Lender hereunder are not subject
                 to United States withholding tax, the Borrower shall withhold
                 taxes from such payments at the applicable statutory rate.
                 Each Lender agrees to indemnify and hold harmless from any
                 United States taxes, penalties, interest and other expenses,
                 costs and losses incurred or payable by (i) the Agent as a
                 result of such Lender's failure to submit any form or
                 certificate that it is required to provide pursuant to this
                 Section 4.05 or (ii) the Borrower or the Agent as a result of
                 their reliance on any such form or certificate which such
                 Lender has provided to them pursuant to this Section 4.05.

                          (ii)    For any period with respect to which a Lender
                 has failed to provide the Borrower with the form required
                 pursuant to this Section 4.05, if any, (other than if such
                 failure is due to a change in a Governmental Requirement
                 occurring subsequent to the date on which a form originally
                 was required to be provided), such Lender shall not be
                 entitled to indemnificationunder Section 4.05 with

                 respect to taxes imposed by the United States which taxes
                 would not have been imposed but for such failure to provide
                 such forms; provided, however, that should a Lender, which is
                 otherwise exempt from or subject to a reduced rate of
                 withholding tax becomes subject to taxes because of its
                 failure to deliver a form required hereunder, the Borrower
                 shall take such steps as such Lender shall reasonably request
                 to assist such Lender to recover such taxes.

                          (iii)   Any Lender claiming any additional amounts
                 payable pursuant to this Section 4.05 shall use reasonable
                 efforts (consistent with legal and regulatory restrictions) to
                 file any certificate or document requested by the Borrower or
                 the Agent or to change the jurisdiction of its Applicable
                 Lending Office or to contest any tax imposed if the making of
                 such a filing or change or contesting such tax would avoid the
                 need for or reduce the amount of any such additional amounts
                 that may thereafter accrue and would not, in the sole
                 determination of such Lender, be otherwise disadvantageous to
                 such Lender.

                 Section 5.01     Additional Costs, Etc.

                 (a)      Eurodollar Regulations, Etc.  The Borrower shall pay
         directly to each Lender from time to time such amounts as such Lender
         may determine to be necessary to compensate such Lender for any costs
         which it determines are attributable to its making or maintaining of
         any Eurodollar Loans or issuing or participating in Letters of Credit
         hereunder or its obligation to make any Eurodollar Loans or issue or
         participate in any Letters of Credit hereunder, or any reduction in
         any amount receivable by such Lender hereunder in respect of any of
         such Eurodollar Loans, Letters of Credit or such obligation (such
         increases in costs and reductions in amounts receivable being herein
         called "Additional Costs"), resulting from any Regulatory Change
         which: (i) changes the basis of taxation of any amounts payable to
         such Lender under this Agreement or any Note in respect of any of such
         Eurodollar Loans or Letters of Credit (other than taxes imposed on the
         overall net income of such Lender or of its Applicable Lending Office
         for any of such Eurodollar Loans by the jurisdiction in which such
         Lender has its principal office or Applicable Lending Office); or (ii)
         imposes or modifies any reserve, special deposit, minimum capital,
         capital ratio or similar requirements (other than the Reserve
         Requirement utilized in the determination of the Fixed Rate for such
         Loan) relating to any extensions of credit or other assets of, or any
         deposits with or other liabilities of such Lender (including any of

         Commitment of such Lender or the Eurodollar interbank market; or (iii)
         imposes any other condition affecting this Agreement or any Note (or
         any of such extensions of credit or liabilities) or such Lender's
         Commitment.  Each Lender will notify the Agent and the Borrower of any
         event occurring after the Closing Date which will entitle such Lender
         to compensation pursuant to this Section 5.01(a) as promptly as
         practicable after it obtains knowledge thereof and determines to
         request such compensation, and will designate a different Applicable
         Lending Office for the Loans of such Lender affected by such event if
         such designation will avoid the need for, or reduce the amount of,
         such compensation and will not, in the sole opinion of such Lender, be
         disadvantageous to such Lender, provided that such Lender shall have
         no obligation to so designate an Applicable Lending Office located in
         the United States.  If any Lender requests compensation from the
         Borrower under this Section 5.01(a), the Borrower may, by notice to
         such Lender, suspend the obligation of such Lender to make additional
         Loans of the Type with respect to which such compensation is requested
         until the Regulatory Change giving rise to such request ceases to be
         in effect (in which case the provisions of Section 5.04 shall be
         applicable).

                 (b)      Regulatory Change.  Without limiting the effect of
         the provisions of Section 5.01(a), in the event that, by reason of any
         Regulatory Change or any other circumstances arising after the Closing
         Date affecting such Lender, the Eurodollar interbank market or such
         Lender's position in such market, any Lender either (i) incurs
         Additional Costs based on or measured by the excess above a specified
         level of the amount of a category of deposits or other liabilities of
         such Lender which includes deposits by reference to which the interest
         rate on Eurodollar Loans is determined as provided in this Agreement
         or a category of extensions of credit or other assets of such Lender
         which includes Eurodollar Loans or (ii) becomes subject to
         restrictions on the amount of such a category of liabilities or assets
         which it may hold, then, if such Lender so elects by notice to the
         Borrower, the obligation of such Lender to make additional Eurodollar
         Loans shall be suspended until such Regulatory Change or other
         circumstances ceases to be in effect (in which case the provisions of
         Section 5.04 shall be applicable).

                 (c)      Capital Adequacy.  Without limiting the effect of the
         foregoing provisions of this Section 5.01 (but without duplication),
         the Borrower shall pay directly to any Lender from time to time on
         request such amounts as such Lender may reasonably determine to be
         necessary to compensate such Lender or its parent or holding company
         for any costs which it determines are attributable to the maintenance
         by such Lender or its parent or holding company (or any Applicable
         Lending Office), pursuant to any Governmental Requirement following
         any Regulatory Change, of capital in respect of its Commitment, its
         Note, or its Loans or any interest held by it in any Letter of Credit,
         such compensation to include, without limitation, an amount equal to
         any reduction of

         the rate of return on assets or equity of such Lender or its parent or
         holding company (or any Applicable Lending Office) to a level below
         that which such Lender or its parent or holding company (or any
         Applicable Lending Office) could have achieved but for such
         Governmental Requirement.  Such Lender will notify the Borrower that
         it is entitled to compensation pursuant to this Section 5.01(c) as
         promptly as practicable after it determines to request such
         compensation.

                 (d)      Compensation Procedure.  Any Lender notifying the
         Borrower of the incurrence of additional costs under this Section 5.01
         shall in such notice to the Borrower and the Agent set forth in
         reasonable detail the basis and amount of its request for
         compensation.  Determinations and allocations by each Lender for
         purposes of this Section 5.01 of the effect of any Regulatory Change
         pursuant to Section 5.01(a) or (b), or of the effect of capital
         maintained pursuant to Section 5.01(c), on its costs or rate of return
         of maintaining Loans or its obligation to make Loans or issue Letters
         of Credit, or on amounts receivable by it in respect of Loans or
         Letters of Credit, and of the amounts required to compensate such
         Lender under this Section 5.01, shall be conclusive and binding for
         all purposes, provided that such determinations and allocations are
         made on a reasonable basis and further provided that additional costs
         incurred more than 180 days prior to notice thereof to the Borrower
         shall not be reimbursable.  Any request for additional compensation
         under this Section 5.01 shall be paid by the Borrower within thirty
         (30) days of the receipt by the Borrower of the notice described in
         this Section 5.01(d).

                 (e)      Replacement of Bank.  In the event that any Bank
         shall require payment of any additional costs pursuant to this Section
         5.01, the Borrower shall have the right (without prejudice to its
         obligations to pay such additional costs) to replace such Bank (a
         "Replaced Bank") with another commercial bank or other financial
         institution (a "Replacement Bank"); provided that such Replacement
         Bank (a) shall be reasonably acceptable to the Agent and (b) offers to
         purchase the Replaced Bank's Loan position at par together with all
         accrued and unpaid interest and fees and to execute and deliver to the
         Agent an Assignment pursuant to Section 12.06 hereof pursuant to which
         such Replacement Bank will become a party hereto with a Commitment
         equal to that of the Bank being replaced.  If the Replaced Bank fails
         to accept such purchase offer, the Borrower shall not obligated to pay
         to such Replaced Bank such additional amounts incurred or accrued from
         and after the date of such purchase offer.

                 Section 5.02     Limitation on Eurodollar Loans.  Anything
herein to the contrary notwithstanding, if, on or prior to the determination of
any Fixed Eurodollar Rate for any Interest Period:





                                      -37-

                                                                    EXHIBIT 1.1




                 (i)      the Agent determines (which determination shall be
         conclusive, absent manifest error) that quotations of interest rates
         for the relevant deposits referred to in the definition of "Fixed
         Eurodollar Rate" in Section 1.02 are not being provided in the
         relevant amounts or for the relevant maturities for purposes of
         determining rates of interest for Eurodollar Loans as provided herein;
         or

                 (ii)     the Agent determines (which determination shall be
         conclusive, absent manifest error) that the relevant rates of interest
         referred to in the definition of "Fixed Eurodollar Rate" in Section
         1.02 upon the basis of which the rate of interest for Eurodollar Loans
         for such Interest Period is to be determined are not sufficient to
         adequately cover the cost to the Lenders of making or maintaining
         Eurodollar Loans;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans.

                 Section 5.03     Illegality.  Notwithstanding any other
provision of this Agreement, in the event that it becomes unlawful for any
Lender or its Applicable Lending Office to honor its obligation to make or
maintain Eurodollar Loans hereunder, then such Lender shall promptly notify the
Borrower thereof and such Lender's obligation to make Eurodollar Loans shall be
suspended until such time as such Lender may again make and maintain Eurodollar
Loans (in which case the provisions of Section 5.04 shall be applicable).

                 Section 5.04     Base Rate Loans Pursuant to Sections 5.01,
5.02 and 5.03.  If the obligation of any Lender to make Eurodollar Loans shall
be suspended pursuant to Sections 5.01, 5.02 or 5.03 ("Affected Loans"), all
Affected Loans which would otherwise be made by such Lender shall be made
instead as Base Rate Loans (and, if an event referred to in Section 5.01(b) or
Section 5.03 has occurred and such Lender so requests by notice to the
Borrower, all Affected Loans of such Lender then outstanding shall be
automatically converted into Base Rate Loans on the date specified by such
Lender in such notice) and, to the extent that Affected Loans are so made as
(or converted into) Base Rate Loans, all payments of principal which would
otherwise be applied to such Lender's Affected Loans shall be applied instead
to its Base Rate Loans.

                 Section 5.05     Compensation.  The Borrower shall pay to each
Lender within thirty (30) days of receipt of written request of such Lender
(which request shall set forth, in reasonable detail, the basis for requesting
such amounts and which shall be conclusive and binding for all purposes
provided that such determinations are made on a reasonable basis), such amount
or amounts as shall compensate it for any loss, cost, expense or liability
which such Lender determines are attributable to:

                                                                    EXHIBIT 1.1




                 (i)      any payment, prepayment or conversion of a Eurodollar
         Loan properly made by such Lender or the Borrower for any reason
         (including, without limitation, the acceleration of the Loans pursuant
         to Section 10.01) on a date other than the last day of the Interest
         Period for such Loan; or

                 (ii)     any failure by the Borrower for any reason (including
         but not limited to, the failure of any of the conditions precedent
         specified in Article VI to be satisfied) to borrow, continue or
         convert a Eurodollar Loan from such Lender on the date for such
         borrowing, continuation or conversion specified in the relevant notice
         given pursuant to Section 2.02(c).

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the present value (discounted at the interest rate
implied in clause (ii) of this sentence) of the excess, if any, of (i) the
amount of interest which would have accrued on the principal amount so paid,
prepaid or converted or not borrowed for the period from the date of such
payment, prepayment or conversion or failure to borrow to the last day of the
Interest Period for such Loan (or, in the case of a failure to borrow, the
Interest Period for such Loan which would have commenced on the date specified
for such borrowing) at the applicable rate of interest for such Loan provided
for herein over (ii) the interest component of the amount such Lender would
have bid in the London interbank market for Dollar deposits of leading banks in
amounts comparable to such principal amount and with maturities comparable to
such period (as reasonably determined by such Lender).

                 Section 6.02     Initial and Subsequent Loans.  The obligation
of the Lenders to make Loans to the Borrower upon the occasion of each
borrowing hereunder and to issue, renew, extend or reissue Letters of Credit
for the account of the Borrower or any Subsidiary (including the Initial
Funding) is subject to the further conditions precedent that, as of the date of
such Loans and after giving effect thereto:  (i) no Default shall have occurred
and be continuing; (ii) no Material Adverse Effect shall have occurred; and
(iii) the representations and warranties made by the Borrower in Article VII
and in the Security Instruments to which it is a party shall be true on and as
of the date of the making of such Loans or issuance, renewal, extension or
reissuance of a Letter of Credit with the same force and effect as if made on
and as of such date and following such new borrowing, except to the extent such
representations and warranties are expressly limited to an earlier date or the
Agent may expressly consent to the contrary as hereinafter provided.  Each
request for a borrowing or issuance, renewal, extension or reissuance of a
Letter of Credit by the Borrower hereunder shall constitute a certification by
the Borrower to the effect set forth in the preceding sentence (both as of the
date of such notice and, unless the Borrower otherwise notifies the Agent prior
to the date of and immediately following such borrowing or issuance, renewal,
extension or reissuance of a Letter of Credit as of the date thereof).  In
connection with the foregoing, the Borrower may notify the Agent in writing of
any variance or change occurring after the Closing Date in the representations
and warranties and, if the Agent has not notified the Borrower in writing
within ten (10) Days following receipt of such notice that it does not consent
to such change or variance, it shall be deemed to have consented thereto.

                 Section 6.03     Conditions Relating to Letters of Credit. In
addition to the satisfaction of all other conditions precedent set forth in
this Article VI, the issuance, renewal, extension or reissuance of the Letters
of Credit referred to in Section 2.01(b) hereof is subject to the following

         the issuance and at least thirty (30) days prior to the date of the
         renewal, extension or reissuance of each Letter of Credit, the Agent
         shall have received a written request for a Letter of Credit.

                 (b)      Each of the Letters of Credit shall (i) be issued by
         NationsBank, (ii) contain such terms and provisions as are reasonably
         required by NationsBank, (iii) be for the account of the Borrower and
         (iv) expire not later than two (2) days before the Revolving Credit
         Termination Date.

                 (c)      The Borrower shall have duly and validly executed and
         delivered to NationsBank a Letter of Credit Agreement pertaining to
         the Letter of Credit.

                         REPRESENTATIONS AND WARRANTIES

         The Borrower and the Guarantor represent and warrant to the Agent and
the Lenders that (each representation and warranty herein is given as of the
Closing Date and shall be deemed repeated and reaffirmed on the dates of each
borrowing and issuance, renewal, extension or reissuance of a Letter of Credit
as provided in Section 6.02):

                 Section 7.01 Corporate Existence. Each of the Borrower and the
Guarantor: (i) is a corporation duly organized, legally existing and in good
standing under the laws of the jurisdiction of its incorporation; (ii) has all
requisite corporate power, and has all material governmental licenses,
authorizations, consents and approvals necessary to own its assets and carry on
its business as now being or as proposed to be conducted; and (iii) is qualified
to do business in all jurisdictions in which the nature of the business
conducted by it makes such qualification necessary and where failure so to
qualify would have a Material Adverse Effect.

                 Section 7.02 Financial Condition. The audited consolidated
balance sheet of the Guarantor and its Consolidated Subsidiaries and the
unaudited consolidating balance sheet of the Guarantor and its Consolidated
Subsidiaries as at December 31, 1994 and the related consolidated and
consolidating statement of operations, shareholders' equity and cash flow
(consolidated statements only for shareholders' equity and cash flow) of the
Guarantor and its Consolidated Subsidiaries for the fiscal year ended on said
date, with the opinion thereon of KPMG Peat Marwick L.L.P. heretofore furnished
to the Agent and the unaudited consolidated and consolidating balance sheet of
the Guarantor and its Consolidated Subsidiaries as at March 31, 1995 and their
related consolidated and consolidating statements of operations and cash flow of
the Guarantor and its Consolidated Subsidiaries for the three-month period ended
on such date heretofore furnished to the Agent, are complete and correct and
fairly present the consolidated and consolidating financial condition of the
Guarantor and its Consolidated Subsidiaries as at said dates and the results of
its operations for the fiscal year and the three-month period on said dates, all
in accordance with GAAP, as applied on a consistent basis (subject, in the case
of the interim financial statements, to normal year-end adjustments). Neither
the Guarantor nor any Subsidiary has on the Closing Date any material Debt,
contingent liabilities, liabilities for taxes, unusual forward or long-term
commitments or unrealized or anticipated losses from any unfavorable
commitments, except as referred to or reflected or provided for in the Financial
Statements. Since December 31, 1994, there has been no change or event having a
Material Adverse Effect. Since the date of the Financial Statements, neither the
business nor the Properties of the Guarantor or any Subsidiary have been
materially and adversely affected as a result of any fire, explosion,
earthquake, flood, drought, windstorm, accident, strike or other labor
disturbance, embargo, requisition or taking of Property or cancellation of
contracts, permits or concessions by any Governmental Authority, riot,
activities of armed forces or acts of God or of any public enemy.

                 Section 7.03 Litigation. Except as disclosed to the Lenders in
Schedule 7.03 hereto, at the Closing Date there is no litigation, legal,
administrative or arbitral proceeding, investigation or other action of any
nature pending or, to the knowledge of the Borrower threatened against or
affecting the Guarantor or any Subsidiary which involves the possibility of any
judgment or liability against the Guarantor or any Subsidiary for the payment of
money in excess of $500,000 (net of insurance coverage) or which could otherwise
have a Material Adverse Effect.

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

                 Section 7.05 Authority. The Guarantor and each Subsidiary have
all necessary corporate power and authority to execute, deliver and perform its
obligations under the Loan Documents to which it is a party; and the execution,
delivery and performance by the Guarantor and each Subsidiary of the Loan
Documents to which it is a party, have been duly authorized by all necessary
corporate action on its part; and the Loan Documents constitute the legal, valid
and binding obligations of the Guarantor and each Subsidiary, enforceable in
accordance with their terms except to the extent such enforceability may be
affected by bankruptcy, insolvency or other similar laws relating to or
affecting creditor's rights.

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

                 Section 7.07 Use of Loans. The proceeds of the Loans shall be
used for general corporate purposes. Neither the Borrower nor the Guarantor is
engaged principally, or as one of its important activities, in the business of
extending credit for the purpose, whether immediate, incidental or ultimate, of
buying or carrying margin stock (within the meaning of Regulation G, U or X of
the Board of Governors of the Federal Reserve System) and no part of the
proceeds of any Loan hereunder will be used to buy or carry any margin stock.

                  Section 7.08     ERISA.

                 (a) The Guarantor, each Subsidiary and each ERISA Affiliate
         have complied in all material respects with ERISA and, where
         applicable, the Code regarding each Plan.

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

                 (c) No act, omission or transaction has occurred which could
         result in imposition on the Guarantor, any Subsidiary or any ERISA
         Affiliate (whether directly or indirectly) of (i) either a civil
         penalty assessed pursuant to section 502(c), (i) or (l) of ERISA or a
         tax imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii)
         breach of fiduciary duty liability damages under section 409 of ERISA.

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

                 (e) Full payment when due has been made of all amounts which
         the Guarantor, any Subsidiary or any ERISA Affiliate is required under
         the terms of each Plan or applicable law to have paid as contributions
         to such Plan, and no accumulated funding deficiency (as defined in
         section 302 of ERISA and section 412 of the Code), whether or not
         waived, exists with respect to any Plan.

                 (f) The actuarial present value of the benefit liabilities
         under each Plan which is subject to Title IV of ERISA does not, as of
         the end of the Guarantor's most recently ended fiscal year, exceed the
         current value of the assets (computed on a plan termination basis in
         accordance with Title IV of ERISA) of such Plan allocable to such
         benefit liabilities by more than $2,000,000. The term "actuarial
         present value of the benefit liabilities" shall have the meaning
         specified in section 4041 of ERISA.

                 (g) None of the Guarantor, any Subsidiary or any ERISA
         Affiliate sponsors, maintains, or contributes to an employee welfare
         benefit plan, as defined in section 3(1) of ERISA, including, without
         limitation, any such plan maintained to provide benefits to former
         employees of such entities, that may not be terminated by the
         Guarantor, a Subsidiary or any ERISA Affiliate in its sole discretion
         at any time without any material liability.

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

                 (i) None of the Guarantor, any Subsidiary or any ERISA
         Affiliate is required to provide security under section 401(a)(29) of
         the Code due to a Plan amendment that results in an increase in current
         liability for the Plan.

                 Section 7.09 Taxes. Except as set out in Schedule 7.09, each of
the Guarantor and its Subsidiaries has filed all United States Federal income
tax returns or appropriate extensions and all other tax returns which are
required to be filed by them and have paid all material taxes due pursuant to
such returns or pursuant to any assessment received by the Guarantor or any
Subsidiary, except those which are being contested in good faith and by
appropriate proceedings diligently conducted. The charges, accruals and reserves
on the books of the Guarantor and its Subsidiaries in respect of taxes and other
governmental charges are, in the opinion of the Borrower, adequate. No tax lien
has been filed and, to the knowledge of the Borrower, no claim is being asserted

         and its Subsidiaries has good and defensible title to its material
         (individually or in the aggregate) Properties, free and clear of all
         Liens except Liens permitted by Section 9.02. Except as set forth in
         Schedule 7.10, after giving full effect to the Excepted Liens, the
         Borrower owns the net interests in production attributable to the
         Hydrocarbon Interests reflected in the most recently delivered Reserve
         Report and the ownership of such Properties shall not in any material
         respect obligate the Borrower to bear the costs and expenses relating
         to the maintenance, development and operations of each such Property in
         an amount in excess of the working interest of each Property set forth
         in the most recently delivered Reserve Report. All information
         contained in the most recently delivered Reserve Report is true and
         correct in all material respects as of the date thereof.

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

                 (c) The rights, properties and other assets presently owned,
         leased or licensed by the Borrower and its Subsidiaries including,
         without limitation, all

         easements and rights of way, include all rights, Properties and other
         assets necessary to permit the Borrower and its Subsidiaries to conduct
         their business in all material respects in the same manner as its
         business has been conducted prior to the Closing Date.

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

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

                 Section 7.12 Investment Company Act. Neither the Guarantor nor
the Borrower nor any Subsidiary is an "investment company" or a company
"controlled" by an "investment company," within the meaning of the Investment
Company Act of 1940, as amended.

                 Section 7.13 Public Utility Holding Company Act. Neither the
Guarantor nor the Borrower nor any Subsidiary is a "holding company," or a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," or a "public
utility" within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

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

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

                 (a) Neither any Property of the Guarantor or any Subsidiary nor
         the operations conducted thereon violate any order or requirement of
         any court or Governmental Authority or any Environmental Laws;

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

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

                 (d) All hazardous substances, solid waste, and oil and gas
         exploration and production wastes, if any, generated at any and all
         Property of the Guarantor or any Subsidiary have in the past been
         transported, treated and disposed of in accordance with Environmental
         Laws and so as not to pose an imminent and substantial endangerment to
         public health or welfare or the environment, and, to the best knowledge
         of the Borrower, all such transport carriers and treatment and disposal
         facilities have been and are operating in compliance with Environmental
         Laws and so as not to pose an imminent and substantial endangerment to
         public health or welfare or the environment, and are not the subject of
         any existing, pending or threatened action, investigation or inquiry by
         any Governmental Authority in connection with any Environmental Laws;

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

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

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

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

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

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

                 Section 7.21 Material Agreements. Set forth on Schedule 7.21
hereto is a complete and correct list of all material credit agreements,
indentures, purchase agreements, obligations in respect of letters of credit,
guarantees, joint venture agreements, and other instruments in effect or to be
in effect as of the Closing Date (other than Hedging Agreements) providing for,
evidencing, securing or otherwise relating to any Debt of the Guarantor or any
of its Subsidiaries, and all obligations of the Guarantor or any of its
Subsidiaries to issuers of surety or appeal bonds issued for account of the
Guarantor or any such Subsidiary. Such list correctly sets forth the names of
the debtor or lessee and creditor or lessor with respect to the Debt or lease
obligations (except with respect to mineral leases which do not create or are
not otherwise subject to Debt) outstanding or to be outstanding and the property
subject to any Lien securing such Debt or lease obligation.

                 Section 7.22 Gas Imbalances. As of April 30, 1995, except as
set forth on Schedule 7.22 or on the most recent certificate delivered pursuant
to Section 8.07(c), on a net basis there are no gas imbalances, take or pay or
other prepayments with respect to the Borrower's Oil and Gas Properties which
would require the Borrower to deliver Hydrocarbons produced from the Oil and Gas
Properties at some future time without then or thereafter receiving full payment
therefor exceeding 200,000 cubic feet of gas in the aggregate.

                                  ARTICLE VIII

                              AFFIRMATIVE COVENANTS

         operations of the Guarantor and its Consolidated Subsidiaries as at the
         end of, and for, such fiscal year and that such financial statements
         have been prepared in accordance with GAAP except for such changes in
         such principles with which the independent public accountants shall

         fiscal year, accompanied by the certificate of a Responsible Officer of
         the Guarantor in the form of Exhibit G attached hereto.

                 (d) As soon as available and in any event within 45 days after

         fiscal year of the Borrower, consolidated statements of operations of

Affiliates and its and its Affiliates' officers, directors, employees,

or provided for in, or received by any of them under, this Agreement, or for the
value, validity, effectiveness, genuineness, execution, effectiveness, legality,
enforceability or sufficiency of this Agreement, any Note or any other document
referred to or provided for herein or for any failure by the Borrower or any

collateral security or the financial or other condition of the Borrower, its
Subsidiaries or any other obligor or guarantor; (iii) except pursuant to Section

omitted to be taken by it hereunder or under any other document or instrument
referred to or provided for herein or in connection herewith including its own
ordinary negligence, except for its own gross negligence or willful misconduct.
The Agent may employ agents, accountants, attorneys and experts and shall not be
responsible for the negligence or misconduct of any such agents, accountants,
attorneys or experts selected by it in good faith or any action taken or omitted
to be taken in good faith by it in accordance with the advice of such agents,
accountants, attorneys or experts. The Agent may deem and treat the payee of any
Note as the holder thereof for all purposes hereof unless and until a written
notice of the assignment or transfer thereof permitted hereunder shall have been
filed with the Agent.

Borrower specifying such Default and stating that such notice is a "Notice of
Default." In the event that the Agent receives such a notice of the occurrence
of a Default, the Agent shall give prompt notice thereof to the Lenders. In the
event of a payment Default, the Agent shall give each Lender prompt notice of
each such payment Default.

                 Section 11.04 Rights as a Lender. With respect to its
Commitments and the Loans made by it and its participation in the issuance of
Letters of Credit, the Agent (and any successor acting as Agent) in its capacity
as a Lender hereunder shall have the same rights and powers hereunder as any
other Lender and may exercise the same as though it were not acting as the
Agent, and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include the Agent in its individual capacity. The Agent (and any
successor acting as Agent) and its Affiliates may (without having to account
therefor to any Lender) accept deposits from, lend money to and generally engage
in any kind of banking, trust or other business with the Borrower (any and of
its Affiliates) as if it were not acting as the Agent, and the Agent and its
Affiliates may accept fees and other consideration from the Borrower for
services in connection with this Agreement or otherwise without having to
account for the same to the Lenders.

                 Section 11.05 INDEMNIFICATION. THE LENDERS AGREE TO INDEMNIFY
THE AGENT RATABLY IN ACCORDANCE WITH THEIR PERCENTAGE SHARES FOR THE INDEMNITY
MATTERS AS DESCRIBED IN SECTION 12.03 TO THE EXTENT NOT INDEMNIFIED OR
REIMBURSED BY THE BORROWER UNDER SECTION 12.03, BUT WITHOUT LIMITING THE
OBLIGATIONS OF THE BORROWER UNDER SAID SECTION 12.03 AND FOR ANY AND ALL OTHER
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS,
COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER WHICH MAY BE
IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF: (I) THIS AGREEMENT, THE SECURITY INSTRUMENTS OR ANY OTHER
DOCUMENTS CONTEMPLATED BY OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED
HEREBY, BUT EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL
ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS AGENCY
DUTIES HEREUNDER OR (II) THE ENFORCEMENT OF ANY OF THE TERMS OF THIS AGREEMENT,
ANY SECURITY INSTRUMENT OR OF ANY SUCH OTHER DOCUMENTS; WHETHER OR NOT ANY OF
THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE SOLE OR CONCURRENT
NEGLIGENCE OF THE AGENT, PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY OF THE
FOREGOING TO THE EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE AGENT.

                 Section 11.06 Non-Reliance on Agent and other Lenders. Each
Lender acknowledges and agrees that it has, independently and without reliance
on the Agent or any other Lender, and based on such documents and information as
it has deemed appropriate, made its own credit analysis of the Borrower and its
decision to enter into this Agreement, and that it will, independently and
without reliance upon the Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own analysis and decisions in taking or not taking action under this Agreement.
The Agent shall not be required to keep itself informed as to the performance or
observance by the Borrower of this Agreement, the Notes, the Security
Instruments or any other document referred to or provided for herein or to
inspect the properties or books of the Borrower. Except for notices, reports and
other documents and information expressly required to be furnished to the
Lenders

by the Agent hereunder, the Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs,
financial condition or business of the Borrower (or any of its Affiliates) which
may come into the possession of the Agent or any of its Affiliates.

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

                 Section 11.08 Resignation or Removal of Agent. Subject to the
appointment and acceptance of a successor Agent as provided below, the Agent may
resign at any time by giving notice thereof to the Lenders and the Borrower, and
the Agent may be removed at any time with or without cause by the Majority
Lenders. Upon any such resignation or removal, the Majority Lenders shall have
the right to appoint a successor Agent. If no successor Agent shall have been so
appointed by the Majority Lenders and shall have accepted such appointment
within thirty (30) days after the retiring Agent's giving of notice of
resignation or the Majority Lenders' removal of the retiring Agent, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent. Upon
the acceptance of such appointment hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation or removal hereunder as Agent, the provisions of
this Article XI and Section 12.03 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Agent.

operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under any of the Loan Documents preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The remedies provided herein are cumulative and not exclusive of any remedies

                 Section 12.05 Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

                 Section 12.06 Assignments and Participations.

                 (a) The Borrower may not assign its rights or obligations
         hereunder or under the Notes or any Letters of Credit without the prior
         consent of all of the Lenders and the Agent.

                 (b) In the event the Aggregate Maximum Credit Amounts are
         changed to exceed $35,000,000, any Lender may, upon the written consent
         of the Agent and the Borrower (which consent will not be unreasonably
         withheld), assign to one or more assignees (provided such assignees are
         commercial banks) all or a portion of its rights and obligations under
         this Agreement pursuant to an Assignment Agreement substantially in the
         form of Exhibit E (an "Assignment"); provided, however, that (i) any
         such assignment shall be in the amount of at least $10,000,000 or such
         lesser amount to which the Borrower has consented, (ii) if the assignee
         Lender remains a Lender, it shall retain a Commitment of at least
         $10,000,000 and (iii) the assignee shall pay to the Agent a processing
         and recordation fee of $2,500 for each assignment. Any such assignment
         will become effective upon the execution and delivery to the Agent of
         the Assignment and the consent of the Agent. Promptly after receipt of
         an executed Assignment, the Agent shall

                                                                     EXHIBIT 1.1

         send to the Borrower a copy of such executed Assignment. Upon receipt
         of such executed Assignment, the Borrower, will, at its own expense,
         execute and deliver new Notes to the assignor and/or assignee, as
         appropriate, in accordance with their respective interests as they
         appear. Upon the effectiveness of any assignment pursuant to this
         Section 12.06(b), the assignee will become a "Lender," if not already a
         "Lender," for all purposes of this Agreement and the Security
         Instruments. The assignor shall be relieved of its obligations
         hereunder to the extent of such assignment (and if the assigning Lender
         no longer holds any rights or obligations under this Agreement, such
         assigning Lender shall cease to be a "Lender" hereunder except that its
         rights under Sections 4.05, 5.01, 5.05 and 12.03 shall not be
         affected). The Agent will prepare on the last Business Day of each
         month during which an assignment has become effective pursuant to this
         Section 12.06(b), a new Exhibit E giving effect to all such assignments
         effected during such month, and will promptly provide the same to the
         Borrower and each of the Lenders.

                 (c) Each Lender may transfer, grant or assign participations in
         all or any part of such Lender's interests hereunder pursuant to this
         Section 12.06(c) to any Person, provided that: (i) such Lender shall
         remain a "Lender" for all purposes of this Agreement and the transferee
         of such participation shall not constitute a "Lender" hereunder; and
         (ii) no participant under any such participation shall have rights to
         approve any amendment to or waiver of any of the Loan Documents except
         to the extent such amendment or waiver would (x) extend the Revolving
         Credit Termination Date, (y) reduce the interest rate (other than as a
         result of waiving the applicability of any post-default increases in
         interest rates) or fees applicable to any of the Commitments or Loans
         or Letters of Credit in which such participant is participating, or
         postpone the payment of any thereof, or (z) release all or
         substantially all of the collateral (if any and except as expressly
         provided in the Security Instruments) supporting any of the Commitments
         or Loans or Letters of Credit in which such participant is
         participating. In the case of any such participation, the participant
         shall not have any rights under this Agreement or any of the Security
         Instruments (the participant's rights against the granting Lender in
         respect of such participation to be those set forth in the agreement
         with such Lender creating such participation), and all amounts payable
         by the Borrower hereunder shall be determined as if such Lender had not
         sold such participation. In addition, each agreement creating any
         participation must include an agreement by the participant to be bound
         by the provisions of Section 12.15.

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

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

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

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

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

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

                 Section 12.10 Survival. The obligations of the parties under
Section 4.05, Article V, and Sections 11.05 and 12.03 shall survive the
repayment of the Loans and the termination of the Commitments. To the extent
that any payments on the Indebtedness or proceeds of any collateral are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, debtor in possession, receiver or other
Person under any bankruptcy law, common law or equitable cause, then to such
extent, the Indebtedness so satisfied shall be revived and continue as if such
payment or proceeds had not been received and the Agent's and the Lenders'
Liens, security interests, rights, powers and remedies under this Agreement and
each Security Instrument shall continue in full force and effect. In such event,
each Security Instrument shall be automatically reinstated, and the Borrower and
the Guarantor shall take such action as may be reasonably requested by the Agent
and the Lenders to effect such reinstatement.

                 (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND
         CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS EXCEPT TO
         THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CHARGE
         INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER
         IS LOCATED. TEX. REV. CIV. STAT. ANN. ART. 5069, CH. 15 (WHICH
         REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING
         TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES.

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

                 Section 12.14 Interest.  It is the intention of the parties
hereto that each Lender shall conform strictly to usury laws applicable to it. 
Accordingly, if the transactions

contemplated hereby would be usurious as to any Lender under laws applicable to
it (including the laws of the United States of America and the State of Texas or
any other jurisdiction whose laws may be mandatorily applicable to such Lender
notwithstanding the other provisions of this Agreement), then, in that event,
notwithstanding anything to the contrary in any of the Loan Documents or any
agreement entered into in connection with or as security for the Notes, it is
agreed as follows: (i) the aggregate of all consideration which constitutes
interest under law applicable to any Lender that is contracted for, taken,
reserved, charged or received by such Lender under any of the Loan Documents or
agreements or otherwise in connection with the Notes shall under no
circumstances exceed the maximum amount allowed by such applicable law, and any
excess shall be cancelled automatically and if theretofore paid shall be
credited by such Lender on the principal amount of the Indebtedness (or, to the
extent that the principal amount of the Indebtedness shall have been or would
thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in
the event that the maturity of the Notes is accelerated by reason of an election
of the holder thereof resulting from any Event of Default under this Agreement
or otherwise, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Lender may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Agreement or otherwise shall be
cancelled automatically by such Lender as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by such Lender on the
principal amount of the Indebtedness (or, to the extent that the principal
amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by such Lender to the Borrower). All sums paid or agreed to be paid to
any Lender for the use, forbearance or detention of sums due hereunder shall, to
the extent not prohibited by law applicable to such Lender, be amortized,
prorated, allocated and spread throughout the full term of the Loans evidenced
by the Notes until payment in full so that the rate or amount of interest on
account of any Loans hereunder does not exceed the maximum amount allowed by
such applicable law. If at any time and from time to time (i) the amount of
interest payable to any Lender on any date shall be computed at the Highest
Lawful Rate applicable to such Lender pursuant to this Section 12.14 and (ii) in
respect of any subsequent interest computation period the amount of interest
otherwise payable to such Lender would be less than the amount of interest
payable to such Lender computed at the Highest Lawful Rate applicable to such
Lender, then the amount of interest payable to such Lender in respect of such
subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to such Lender until the total amount of interest
payable to such Lender shall equal the total amount of interest which would have
been payable to such Lender if the total amount of interest had been computed
without giving effect to this Section 12.14; but this sentence shall not affect
the ability of the Borrower to repay the Loans as provided in this Agreement. To
the extent that Article 5069-1.04 of the Texas Revised Civil Statutes is
relevant for the purpose of determining the Highest Lawful Rate, such Lender
elects to determine the applicable rate ceiling under such Article by the
indicated weekly rate ceiling from time to time in effect.

                 Section 12.15 Confidentiality. All information provided to the
Agent or any Lender hereunder (other than under Section 8.01(g) shall, unless
otherwise specified by the Borrower or the Guarantor in writing, be deemed
"confidential", the Agent and the Lenders shall thereafter maintain such

domain without the Agent or the Lenders breaching their obligation of confidence
to the Borrower and the Guarantor, (iii) are previously known by the Agent or
the Lenders from some source other than the Borrower or the Guarantor, (iv) are
hereafter developed by the Agent or the Lenders without using the Borrower's or
the Guarantor's information, (v) are hereafter obtained by or available to the
Agent or the Lenders from a third party who owes no obligation of confidence to
the Borrower or the Guarantor with respect to such information or through any
other means other than through disclosure by the Borrower or the Guarantor, (vi)
are disclosed with the Borrower's or the Guarantor's consent, (vii) must be
disclosed either pursuant to any Governmental Requirement or to Persons
regulating the activities of the Agent or the Lenders, or (viii) as may be
required by law or regulation or order of any Governmental Authority in any
judicial, arbitration or governmental proceeding. Further, the Agent or a Lender
may disclose any such information to any other Lender, any independent petroleum
engineers or consultants, any independent certified public accountants, any
legal counsel employed by such Person in connection with this Agreement or any
Security Instrument, including without limitation, the enforcement or exercise
of all rights and remedies thereunder, or any assignee or participant (including
prospective assignees and participants) in the Loans; provided, however, that
the Agent or Lender imposes on the Person to whom such information is disclosed
the same obligation to maintain the confidentiality of such information as is
imposed upon it hereunder.

                 Section 12.16 Effectiveness. This Agreement shall be effective
on the date of execution hereof by all parties hereto (the "Effective Date").

                                    ARTICLE 2

                                  The Guaranty

         Section 2.1 Liabilities Guaranteed. Guarantor hereby irrevocably and
unconditionally guarantees the prompt payment at maturity of the Liabilities.

         Section 2.2 Nature of Guaranty. This guaranty is an absolute,
irrevocable, completed and continuing guaranty of payment and not a guaranty of
collection, and no notice of the Liabilities or any extension of credit already
or hereafter contracted by or extended to Borrower need be given to Guarantor.
This guaranty may not be revoked by Guarantor and shall continue to be effective
with respect to debt under the Liabilities arising or created after any
attempted revocation by Guarantor and shall remain in full force and effect
until the Liabilities are paid in full and the Commitments are terminated,
notwithstanding that from time to time prior thereto no Liabilities may be
outstanding. Borrower and the Lenders may modify, alter, rearrange, extend for
any period and/or renew from time to time, the Liabilities, and the Lenders may
waive any Default or Events of Default without notice to the Guarantor and in
such event Guarantor will remain fully bound hereunder on the Liabilities. This
guaranty shall continue to be effective or be reinstated, as the case may be, if
at any time any payment of the Liabilities is rescinded or must otherwise be
returned by the Lenders upon the insolvency, bankruptcy or reorganization of
Borrower or otherwise, all as though such payment had not been made. This
Guaranty Agreement may be enforced by the Agent and shall not be discharged by
the assignment or negotiation of all or part of the Liabilities. Guarantor
hereby expressly waives presentment, demand, notice of non-payment, protest and
notice of protest and dishonor, notice of Event of Default, notice of intent to
accelerate the maturity and notice of acceleration of the maturity and any other
notice in connection with the Liabilities, and also notice of acceptance of this
Guaranty Agreement, acceptance on the part of the Lenders being conclusively
presumed by their request for this Guaranty Agreement and delivery of the same
to the Agent.

        Section 2.3 Agent's Rights. Guarantor authorizes the Agent, without
notice or demand and without affecting Guarantor's liability hereunder, to take
and hold security for the payment of the Liabilities, and exchange, enforce,
waive and release any such security; and to apply such security and direct the
order or manner of sale thereof as the Agent in its discretion may determine;
and to obtain a guaranty of the Liabilities from any one or more Persons and at
any time or times to enforce, waive, rearrange, modify, limit or release any of
such other Persons from their obligations under such guaranties.

        Section 2.4 Guarantor's Waivers. Guarantor waives any right to require
the Lenders to (a) proceed against Borrower or any other person liable on the
Liabilities, (b) enforce its rights against any other guarantor of the
Liabilities, (c) proceed or enforce its rights against or exhaust any security
given to secure the Liabilities, (d) have Borrower joined with Guarantor in any
suit arising out of this Guaranty Agreement and/or the Liabilities, or (e)
pursue any other remedy in the Agent's powers whatsoever. The Agent shall not be
required to mitigate damages or take any action to reduce, collect or enforce
the Liabilities. Guarantor waives any defense arising by reason of any
disability, lack of corporate authority or power, or other defense of Borrower
or any other guarantor of the Liabilities, and shall remain liable hereon
regardless of whether Borrower or any other guarantor be found not liable
thereon for any reason. Until the Liabilities shall have been paid in full,
Guarantor shall have no right of subrogation, and waives any right to enforce
any remedy which the Lenders now has or may hereafter have against Borrower, and
waives any benefit of any right to participate in any security now or hereafter
held by the Lenders. Whether and when to exercise any of the remedies of the
Lenders under any of the Loan Documents shall be in the sole and absolute
discretion of the Agent, and no delay by the Agent in enforcing any remedy,
including delay in conducting a foreclosure sale, shall be a defense to the
Guarantor's liability under this Guaranty Agreement. To the extent allowed by
applicable law, the Guarantor hereby waives any good faith duty on the part of
the Agent in exercising any remedies provided in the Loan Documents.

        Section 2.5 Maturity of Liabilities; Payment. Guarantor agrees that if
the maturity of the Liabilities is accelerated by bankruptcy or otherwise, such
maturity shall also be deemed accelerated for the purpose of this Guaranty
Agreement without demand or notice to Guarantor. Guarantor will, forthwith upon
notice from the Agent of Borrower's failure to pay the Liabilities at maturity,
pay to the Agent the amount due and unpaid by Borrower and guaranteed hereby.
The failure of the Agent to give this notice shall not in any way release
Guarantor hereunder, but Guarantor shall have no obligation to make any payment
hereunder until it receives notice from the Agent of the Borrower's failure to
pay the Liabilities.

        Section 2.6 Agent's Expenses. If Guarantor fails to pay the Liabilities
after notice from the Agent of Borrower's failure to pay any Liabilities at
maturity, and if the Agent obtains the services of an attorney for collection of
amounts owing by Guarantor hereunder, or obtaining advice of counsel in respect
of any of its rights under this Guaranty Agreement, or if suit is filed to
enforce this Guaranty Agreement, or if proceedings are had in any bankruptcy,
probate, receivership or other judicial proceedings for the establishment or
collection of any amount owing by Guarantor hereunder, or if any amount owing by
Guarantor hereunder is collected

through such proceedings, Guarantor agrees to pay to the Agent at its banking
quarters the Agent's reasonable attorneys' fees.

        Section 2.7  Liability. It is expressly agreed that the liability of the
Guarantor for the payment of the Liabilities guaranteed hereby shall be primary
and not secondary.

        Section 2.8  Events and Circumstances Not Reducing or Discharging
Guarantor's Obligations. Guarantor hereby consents and agrees to each of the
following to the fullest extent permitted by law, and agrees that Guarantor's
obligations under this Guaranty Agreement shall not be released, diminished,
impaired, reduced or adversely affected by any of the following, and waives any
rights (including without limitation rights to notice) which Guarantor might
otherwise have as a result of or in connection with any of the following:

                (a)  Modifications, etc. Any renewal, extension, modification,
         increase, decrease, alteration or rearrangement of all or any part of
         the Liabilities, or of the Notes, or the Credit Agreement or any
         instrument executed in connection therewith, or any contract or
         understanding between Borrower and the Lenders, or any other Person,
         pertaining to the Liabilities;

                (b)  Adjustment, etc. Any adjustment, indulgence, forbearance or
         compromise that might be granted or given by the Lenders to Borrower or
         Guarantor or any Person liable on the Liabilities;

                (c)  Condition of Borrower or Guarantor. The insolvency,
         bankruptcy arrangement, adjustment, composition, liquidation,
         disability, dissolution, death or lack of power of Borrower or
         Guarantor or any other Person at any time liable for the payment of all
         or part of the Liabilities; or any dissolution of Borrower or
         Guarantor, or any sale, lease or transfer of any or all of the assets
         of Borrower or Guarantor, or any changes in the shareholders, partners,
         or members of Borrower or Guarantor; or any reorganization of Borrower
         or Guarantor;

                (d)  Invalidity of Liabilities. The invalidity, illegality or
         unenforceability of all or any part of the Liabilities, or any document
         or agreement executed in connection with the Liabilities, for any
         reason whatsoever, including without limitation the fact that the
         Liabilities, or any part thereof, exceed the amount permitted by law,
         the act of creating the Liabilities or any part thereof is ultra vires,
         the officers or representatives executing the documents or otherwise
         creating the Liabilities acted in excess of their authority, the
         Liabilities violate applicable usury laws, the creation, performance or
         repayment of the Liabilities (or the execution, delivery and
         performance of any document or instrument representing part of the
         Liabilities or executed in connection with the Liabilities, or given to
         secure the repayment of the Liabilities) is illegal, uncollectible,
         legally impossible or unenforceable, or the Credit Agreement or other
         documents or instruments

         pertaining to the Liabilities have been forged or otherwise are
         irregular or not genuine or authentic.

                 (e) Release of Obligors. Any full or partial release of the
         liability of Borrower on the Liabilities or any part thereof, of any
         co-guarantors, or any other Person now or hereafter liable, whether
         directly or indirectly, jointly, severally, or jointly and severally,
         to pay, perform, guarantee or assure the payment of the Liabilities or
         any part thereof, it being recognized, acknowledged and agreed by
         Guarantor that Guarantor may be required to pay the Liabilities in full
         without assistance or support of any other Person, and Guarantor has
         not been induced to enter into this Guaranty Agreement on the basis of
         a contemplation, belief, understanding or agreement that other parties
         other than the Borrower will be liable to perform the Liabilities, or
         the Agent will look to other parties to perform the Liabilities.
         Notwithstanding the foregoing, Guarantor does not hereby waive or
         release (expressly or impliedly) any rights of subrogation,
         reimbursement or contribution which it may have, after payment in full
         of the Liabilities, against others liable on the Liabilities;
         Guarantor's rights of subrogation and reimbursement are however,
         subordinate to the rights and claims of the Lenders with respect to the
         Liabilities;

                 (f) Other Security. The taking or accepting of any other
         security, collateral or guaranty, or other assurance of payment, for
         all or any part of the Liabilities;

                 (g) Release of Collateral, etc. Any release, surrender,
         exchange, subordination, deterioration, waste, loss or impairment
         (including without limitation negligent, willful, unreasonable or
         unjustifiable impairment) of any collateral, property or security, at
         any time existing in connection with, or assuring or securing payment
         of, all or any part of the Liabilities;

                 (h) Care and Diligence. The failure of the Agent or any other
         Person to exercise diligence or reasonable care in the preservation,
         protection, enforcement, sale or other handling or treatment of all or
         any part of such collateral, property or security;

                 (i) Status of Liens. The fact that any collateral, security,
         security interest or lien contemplated or intended to be given, created
         or granted as security for the repayment of the Liabilities shall not
         be properly perfected or created, or shall prove to be unenforceable or
         subordinate to any other security interest or lien, it being recognized
         and agreed by Guarantor that Guarantor is not entering into this
         Guaranty Agreement in reliance on, or in contemplation of the benefits
         of, the validity, enforceability, collectibility or value of any of the
         collateral for the Liabilities. Notwithstanding the foregoing,
         Guarantor does not hereby waive or release (expressly or impliedly) any
         right to be subrogated to the rights of the Lenders in any collateral
         or security for the Liabilities, after payment in full of the

        Liabilities; Guarantor's rights of subrogation are, however, subordinate
        to the rights, claims, liens and security interests of the Lenders with
        respect to the Liabilities;

                 (j) Payments Rescinded. Any payment by Borrower to the Lenders
        is held to constitute a preference under the bankruptcy laws, or for any
        reason the Lenders are required to refund such payment or pay such
        amount to Borrower or someone else; or

                 (k) Other Actions Taken or Omitted. Any other action taken or
        omitted to be taken with respect to the Credit Agreement, the
        Liabilities, or the security and collateral therefor, whether or not
        such action or omission prejudices Guarantor or increases the likelihood
        that Guarantor will be required to pay the Liabilities pursuant to the
        terms hereof; it being the unambiguous and unequivocal intention of
        Guarantor that Guarantor shall be obligated to pay the Liabilities when
        due, notwithstanding any occurrence, circumstance, event, action, or
        omission whatsoever, whether contemplated or uncontemplated, and whether
        or not otherwise or particularly described herein, except for the full
        and final payment and satisfaction of the Liabilities.

                         Representations and Warranties

        Section 3.1 By Guarantor. In order to induce the Agent to accept this
Guaranty Agreement, Guarantor represents and warrants to the Agent (which
representations and warranties will survive the creation of the Liabilities and
any extension of credit thereunder) that:

                (a) Benefit to Guarantor. Guarantor's guaranty pursuant to this
        Guaranty Agreement reasonably may be expected to benefit, directly or
        indirectly, Guarantor.

                (b) Solvency. The Guarantor hereby represents that (i) it is
        not insolvent as of the date hereof and will not be rendered insolvent
        as a result of this Guaranty Agreement, (ii) it is not engaged in
        business or a transaction, or about to engage in a business or a
        transaction, for which any property or assets remaining with such
        Guarantor is unreasonably small capital, and (iii) it does not intend to
        incur, or believe it will incur, debts that will be beyond its ability
        to pay as such debts mature.

        Section 3.2 No Representation by Agent. Neither the Agent nor any other
Person has made any representation, warranty or statement to the Guarantor in
order to induce the Guarantor to execute this Guaranty Agreement.

                                    ARTICLE 4

                          Subordination of Indebtedness

         Section 4.1 Subordination of All Guarantor Claims. As used herein, the
term "GUARANTOR CLAIMS" shall mean all debts and liabilities of Borrower to
Guarantor, whether such debts and liabilities now exist or are hereafter
incurred or arise, or whether the obligation of Borrower thereon be direct,
contingent, primary, secondary, several, joint and several, or otherwise, and
irrespective of whether such debts or liabilities be evidenced by note,
contract, open account, or otherwise, and irrespective of the person or persons
in whose favor such debts or liabilities may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter
be acquired by Guarantor. The Guarantor Claims shall include without limitation
all rights and claims of Guarantor against Borrower arising as a result of
subrogation or otherwise as a result of Guarantor's payment of all or a portion
of the Liabilities.

         Section 4.2 Claims in Bankruptcy. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor's relief, or other insolvency
proceedings involving Borrower as debtor, the Agent shall have the right to
prove the Lenders' claim in any proceeding, so as to establish the Agent's
rights hereunder and receive directly from the receiver, trustee or other court
custodian, dividends and payments which would otherwise be payable upon
Guarantor Claims. Guarantor hereby assigns such dividends and payments to the
Agent until the payment in full of the Liabilities. Should the Lenders receive,
for application upon the Liabilities, any such dividend or payment which is
otherwise payable to Guarantor, and which, as between Borrower and Guarantor,
shall constitute a credit upon the Guarantor Claims, then upon payment in full
of the Liabilities, Guarantor shall become subrogated to the rights of the
Lenders to the extent that such payments to the Lenders on the Guarantor Claims
have contributed toward the liquidation of the Liabilities, and such subrogation
shall be with respect to that proportion of the Liabilities which would have
been unpaid if the Lenders had not received dividends or payments upon the
Guarantor Claims.

         Section 4.3 Payments Held in Trust. In the event that notwithstanding
Sections 4.1 and 4.2 above, Guarantor should receive any funds, payments, claims
or distributions which is prohibited by such Sections, Guarantor agrees to hold
in trust for the Agent an amount equal to the amount of all funds, payments,
claims or distributions so received, and agrees that it shall have absolutely no
dominion over the amount of such funds, payments, claims or distributions except
to pay them promptly to the Agent, and Guarantor covenants promptly to pay the
same to Agent.

         Section 4.4 Liens Subordinate. Guarantor agrees that any liens,
security interests, judgment liens, charges or other encumbrances upon
Borrower's assets securing payment of the Guarantor Claims shall be and remain
inferior and subordinate to any liens, security interests, judgment liens,
charges or other encumbrances upon Borrower's assets securing payment of the
Liabilities, regardless of whether such encumbrances in favor of Guarantor or
the Agent presently exist or are hereafter created or attach. Without the prior
written consent of the

Agent, Guarantor shall not (a) exercise or enforce any creditor's right it may
have against the Borrower, or (b) foreclose, repossess, sequester or otherwise
take steps or institute any action or proceeding (judicial or otherwise,
including without limitation the commencement of or joinder in any liquidation,
bankruptcy, rearrangement, debtor's relief or insolvency proceeding) to enforce
any lien, mortgages, deeds of trust, security interest, collateral rights,
judgments or other encumbrances on assets of Borrower held by Guarantor;
provided, however, that Guarantor may (in its capacity as shareholder of
Borrower) direct that Borrower commence or join in any liquidation, bankruptcy,
rearrangement, debtor's relief or insolvency proceeding.

        Section 4.5 Notation of Records. All promissory notes, accounts
receivable ledgers or other evidence of the Guarantor Claims accepted by or held
by Guarantor shall contain a specific written notice thereon that the
indebtedness evidenced thereby is subordinated under the terms of this Guaranty
Agreement.

                                    ARTICLE 5

                                  Miscellaneous

        Section 5.1 Successors and Assigns. This Guaranty Agreement is and shall
be in every particular available to the successors and assigns of the Agent and
is and shall always be fully binding upon the successors and assigns of
Guarantor, notwithstanding that some or all of the monies, the repayment of
which this Guaranty Agreement applies, may be actually advanced after any
bankruptcy, receivership, reorganization or other event affecting Guarantor.

        Section 5.2 Notices. Any notice or demand to Guarantor under or in
connection with this Guaranty Agreement may be given and shall conclusively be
deemed and considered to have been given and received in accordance with Section
12.02 of the Credit Agreement, addressed to Guarantor at the address on the
signature page hereof or at such other address as Guarantor may provide to the
Agent in writing.

        Section 5.3 Business and Financial Information. The Guarantor will
promptly furnish to the Agent from time to time upon request such information
regarding the business and affairs and financial condition of the Guarantor and
its subsidiaries as the Agent may reasonably request.

        Section 5.4 Construction. This Guaranty Agreement is a contract made
under and shall be construed in accordance with and governed by the laws of the
State of Texas.
