     2.   COMMITMENTS OF THE BANK.

          (a)       TERMS OF REVOLVING COMMITMENT.  On the terms and conditions
     hereinafter set forth, each Bank agrees severally to make Advances to
     the Borrowers from time to time during the period beginning on the
     Effective Date and ending on the Revolving Maturity Date in such
     amounts as the Borrowers may request up to an amount not to exceed, in
     the aggregate principal amount outstanding at any time, the Revolving
     Commitment.  The obligation of the Borrowers hereunder shall be
     evidenced by this Agreement and the Revolving Notes issued in
     connection herewith, said Revolving Notes to be as described in
     Section 3 hereof.  Notwithstanding any other provision of this
     Agreement, no Advance shall be required to be made hereunder if any
     Event of Default (as hereinafter defined) has occurred and is
     continuing or if any event or condition has occurred or failed to
     occur which with the passage of time or service of notice, or both,
     would constitute an Event of Default.  Each Advance under the
     Revolving Commitment shall be an aggregate amount of at least $100,000
     or a whole number multiple thereof except an Advance of the entire
     remaining unborrowed Revolving Commitment.  Irrespective of the face
     amount of the Revolving Note or Notes, the Banks shall never have the
     obligation to Advance any amount or amounts in excess of the Revolving
     Commitment or to increase the Revolving Commitment.  The total number
     of Tranches under the Revolving Commitment which may be outstanding at
     any time hereunder shall never exceed five (5), whether such Tranches
     are Prime Rate Loans, LIBOR Loans, or a combination thereof.  Within
     the limit of each Bank's Revolving Commitment, the Borrowers may
     borrow, repay and reborrow under this Section 2 prior to the Revolving
     Maturity Date.

                                     -13-


          (b)    PROCEDURE FOR BORROWING.  Whenever the Borrowers desire an
     Advance hereunder, they shall give Agent telegraphic, telex, facsimile
     or telephonic notice ("Notice of Borrowing") of such requested
     Advance, which in the case of telephonic notice, shall be promptly
     confirmed in writing.  Each Notice of Borrowing shall be in the form
     of Exhibit "A" attached hereto and shall be received by Agent not
     later than 11:00 a.m. Oklahoma City, Oklahoma time, (i) one Business
     Day prior to the Borrowing Date in the case of the Prime Rate Loan, or
     (ii) two London Business Days prior to any proposed Borrowing Date in
     the case of LIBOR Loans.  Each Notice of Borrowing shall specify
     (i) the Borrowing Date (which, if at Prime Rate Loan, shall be a
     Business Day and if a LIBOR Loan, a London Business Day), (ii) the
     principal amount to be borrowed, (iii) the portion of the Advance
     constituting Prime Rate Loans and/or LIBOR Loans and (iv) if any
     portion of the proposed Advance is to constitute LIBOR Loans, the
     initial Interest Period selected by Borrowers pursuant to Section 4
     hereof to be applicable thereto.  Upon receipt of such Notice, Agent
     shall advise each Bank thereof; provided, that if the Banks have
     received at least one (1) day's notice of such Advance prior to
     funding of a Prime Rate Loan, or at least two (2) days' notice of each
     Advance prior to funding in the case of a LIBOR Loan, each Bank shall
     provide Agent at its office at 100 North Broadway, Oklahoma City,
     Oklahoma 73125, not later than 1:00 p.m.,Oklahoma City, Oklahoma time,
     on the Borrowing Date, in immediately available funds, its pro rata
     share of the requested Advance, but the aggregate of all such fundings
     by each Bank shall never exceed such Bank's Revolving Commitment.  Not
     later than 2:00 p.m., Oklahoma City, Oklahoma time, on the Borrowing
     Date, Agent shall make available to the Borrowers at the same office,
     in like funds, the aggregate amount of such requested Advance. 
     Neither Agent nor any Bank shall incur any liability to the Borrowers
     in acting upon any Notice of Borrowing which Agent or such Bank
     believes in good faith to have been given by a duly authorized officer
     or other person authorized to borrow on behalf of Borrowers or for
     otherwise acting in good faith under this Section 2(b).  Upon funding
     of Advances by Banks in accordance with this Agreement, pursuant to
     any such Notice, the Borrowers shall have effected Advances hereunder.

          (c)    LETTERS OF CREDIT.  On the terms and conditions hereinafter
     set forth, the Agent shall from time to time during the period
     beginning on the Effective Date and ending on the Revolving Maturity
     Date upon request of Borrowers issue standby and/or commercial Letters
     of Credit for the account of Borrowers (the "Letters of Credit") in
     such face amounts as Borrowers may request, but not to exceed in the
     aggregate face amount at any time outstanding the sum of Ten Million
     Dollars ($10,000,000.00).  The face amount of all Letters of Credit
     issued and outstanding hereunder shall be considered as Advances for
     Borrowing Base purposes and all payments made by the Agent on such
     Letters of Credit shall be considered as Advances under the Revolving
     Notes.  Each Letter of Credit issued 


                                    -14-



     for the account of Borrowers hereunder shall (i) be in favor of such 
     beneficiaries as specifically requested by Borrowers, (ii) have an 
     expiration date not exceeding the earlier of (a) one year or (b) the 
     Revolving Maturity Date, and (iii) contain such other terms and 
     provisions as may be reasonably required by Bank.  Each Bank (other than 
     Agent) agrees that, upon issuance of any Letter of Credit hereunder, it 
     shall automatically acquire a participation in the Agent's liability 
     under such Letter of Credit in an amount equal to such Bank's Revolving 
     Commitment Percentage of such liability, and each Bank (other than 
     Agent) thereby shall absolutely, unconditionally and irrevocably assume, 
     as primary obligor and not as surety, and shall be unconditionally 
     obligated to Agent to pay and discharge when due, its Revolving 
     Commitment Percentage of Agent's liability under such Letter of Credit.  
     The Borrowers hereby unconditionally agree to pay and reimburse the 
     Agent for the amount of each demand for payment under any Letter of 
     Credit that is in substantial compliance with the provisions of any such 
     Letter of Credit at or prior to the date on which payment is to be made 
     by the Agent to the beneficiary thereunder, without presentment, demand, 
     protest or other formalities of any kind.  Upon receipt from any 
     beneficiary of any Letter of Credit of any demand for payment under such 
     Letter of Credit, the Agent shall promptly notify the Borrowers of the 
     demand and the date upon which such payment is to be made by the Agent 
     to such beneficiary in respect of such demand. Forthwith upon receipt of 
     such notice from the Agent, Borrowers shall advise the Agent whether or 
     not they intend to borrow hereunder to finance their obligations to 
     reimburse the Agent, and if so, submit a Notice of Borrowing as provided 
     in Section 2(b) hereof.  If Borrowers fail to so advise Agent and 
     thereafter fail to reimburse Agent, the Agent shall notify each Bank of 
     the demand and the failure of the Borrowers to reimburse the Agent, and 
     each Bank shall reimburse the Agent for its Revolving Commitment 
     Percentage of each such draw paid by the Agent and unreimbursed by the 
     Borrowers.  All such amounts paid by Agent and/or reimbursed by the 
     Banks shall be treated as an Advance or Advances under the Revolving 
     Commitment, which Advances shall be immediately due and payable and 
     shall bear interest at the Default Rate.

          (d)    PROCEDURE FOR OBTAINING LETTERS OF CREDIT.  The amount and
     date of issuance, renewal, extension or reissuance of a Letter of
     Credit pursuant to the Banks' commitment above in Section 2(c) shall
     be designated by Borrowers' written request delivered to Agent at
     least three (3) Business Days prior to the date of such issuance,
     renewal, extension or reissuance.  Concurrently with or promptly
     following the delivery of the request for a Letter of Credit,
     Borrowers shall execute and deliver to the Agent an application and
     agreement with respect to the Letters of Credit, said application and
     agreement to be in the form used by the Agent.  The Agent shall not be
     obligated to issue, renew, extend or reissue such Letters of Credit if
     (A) the amount thereon when added to the face amount of all
     outstanding Letters of Credit plus any Reimbursement Obligations
     exceeds Ten Million Dollars ($10,000,000.00) or (B) the amount thereof
     when added to the Total Outstandings 


                                    -15-



     would exceed the Revolving Commitment.  Borrowers agree to pay the Agent 
     for the benefit of the Banks commissions for issuing the Letters of 
     Credit (calculated separately for each Letter of Credit) in an amount 
     equal to the greater of (i) one percent (1%) per annum on the maximum 
     face amount of the Letter of Credit or (ii) $500.00.  Borrowers further 
     agree to pay Agent an additional fronting fee equal to one-eighth of one 
     percent (.125%) per annum on the maximum face amount of each Letter of 
     Credit.  Such commissions shall be payable prior to the issuance of each 
     Letter of Credit and thereafter on each anniversary date of such 
     issuance while such Letter of Credit is outstanding.

          (e)    VOLUNTARY REDUCTION OF REVOLVING COMMITMENT.  The Borrowers
     may at any time, or from time to time, upon not less than three (3)
     Business Days' prior written notice to Agent, reduce or terminate the
     Revolving Commitment; provided, however, that (i) each reduction in
     the Revolving Commitment must be in the amount of $500,000 or more, in
     increments of $100,000 and (ii) each reduction must be accompanied by
     a prepayment of the Revolving Notes in the amount by which the
     outstanding principal balance of the Revolving Notes exceeds the
     Revolving Commitment as reduced pursuant to this Section 2.

          (f)    MANDATORY COMMITMENT REDUCTIONS -

                 (i)   MONTHLY COMMITMENT REDUCTION.  The Borrowing Base and
          the Revolving Commitment shall be reduced as of the first day of
          each month by an amount determined by the Banks pursuant to
          Section 7(b) hereof (the "Monthly Commitment Reduction").  The
          Monthly Commitment Reduction shall be $0 beginning on June 1,
          1998, with like reductions continuing on the first day of each
          month thereafter until redetermined pursuant to Section 7(b)
          hereof.  If as a result of any such Monthly Commitment Reduction,
          the Total Outstandings ever exceed the Revolving Commitment then
          in effect, the Borrowers shall make the mandatory prepayment of
          principal required pursuant to Section 9(b) hereof.

                 (ii)  OTHER REDUCTIONS.  The Borrowing Base shall be reduced
          from time to time by the amount of any prepayment required by
          Section 12(r) hereof upon the sale of Oil and Gas Properties. 
          If, as a result of any such reduction in the Borrowing Base, the
          Total Outstandings ever exceed the Borrowing Base then in effect,
          the Borrowers shall make the mandatory prepayment of principal
          required pursuant to Section 9(b) hereof.

          (g)    SEVERAL OBLIGATIONS.  The obligations of the Banks under the
     Revolving Commitment are several and not joint.  The failure of any
     Bank to make an Advance required to be made by it shall not relieve
     any other Bank of its obligation to make its Advance, and no Bank
     shall be responsible for the failure of 


                                    -16-



     any other Bank to make the Advance to be made by such other Bank.

     2.   NOTES EVIDENCING LOANS.  The loans described above in Section 2
shall be evidenced by promissory notes of Borrowers as follows:

          (a)    FORM OF REVOLVING NOTES - The Revolving Loan shall be
     evidenced by a Note or Notes in the aggregate face amount of
     $175,000,000, and shall be in the form of Exhibit "B" hereto with
     appropriate insertions (each a "Revolving Note").  Notwithstanding the
     face amount of the Revolving Notes, the actual principal amount due
     from the Borrowers to Banks on account of the Revolving Notes, as of
     any date of computation, shall be the sum of Advances then and
     theretofore made on account thereof, less all principal payments
     actually received by Banks in collected funds with respect thereto. 
     Although the Revolving Notes may be dated as of the Effective Date,
     interest in respect thereof shall be payable only for the period
     during which the loans evidenced thereby are outstanding and, although
     the stated amount of the Revolving Notes may be higher, the Revolving
     Notes shall be enforceable, with respect to Borrowers' obligation to
     pay the principal amount thereof, only to the extent of the unpaid
     principal amount of the loans.  Irrespective of the face amount of the
     Revolving Notes, no Bank shall ever be obligated to advance on the
     Revolving Commitment any amount in excess of its Revolving Commitment
     then in effect.

          (b)    ISSUANCE OF ADDITIONAL NOTES - At the Effective Date there
     shall be outstanding one Revolving Note in the aggregate face amount
     of $175,000,000 payable to the order of Bank One-Oklahoma.  From time
     to time new Notes may be issued to other Banks as such Banks become
     parties to this Agreement.  Upon request from Agent, the Borrowers
     shall execute and deliver to Agent any such new or additional Notes. 
     From time to time as new Notes are issued the Agent shall require that
     each Bank exchange their Notes for newly issued Notes to better
     reflect the extent of each Bank's Revolving Commitment hereunder.  The
     notes replaced shall be marked to indicate that they have been
     replaced and/or returned to the Borrowers.

          (c)    INTEREST RATES - The unpaid principal balance of the Notes
     shall bear interest from time to time as set forth in Section 4
     hereof.

          (d)    PAYMENT OF INTEREST - Interest on the Notes shall be payable
     on each Interest Payment Date.

          (e)    PAYMENT OF PRINCIPAL - Principal of the Revolving Note or
     Notes shall be due and payable to the Agent for the ratable benefit of
     the Banks on the Revolving Maturity Date unless earlier due in whole
     or in part as a result of an acceleration of the amount due or
     pursuant to the mandatory prepayment provisions


                                    -17-



     of Section 9(b) hereof.

          (f)    PAYMENT TO BANKS - Each Bank's Pro Rata Part of each payment
     or prepayment of the Loans shall be directed by wire transfer to such
     Bank by the Agent at the address provided to the Agent for such Bank
     for payments no later than 2:00 p.m., Oklahoma City, Oklahoma, time on
     the Business Day such payments or prepayments are deemed hereunder to
     have been received by Agent; provided, however, in the event that any
     Bank shall have failed to make an Advance as contemplated under
     Section 2 hereof (a "Defaulting Bank") and the Agent or another Bank
     or Banks shall have made such Advance, payment received by Agent for
     the account of such Defaulting Bank or Banks shall not be distributed
     to such Defaulting Bank or Banks until such Advance or Advances shall
     have been repaid in full to the Bank or Banks who funded such Advance
     or Advances.  Any payment or prepayment received by Agent at any time
     after 12:00 noon, Oklahoma City, Oklahoma, time on a Business Day
     shall be deemed to have been received on the next Business Day. 
     Interest shall cease to accrue on any principal as of the end of the
     day preceding the Business Day on which any such payment or prepayment
     is deemed hereunder to have been received by Agent.  If Agent fails to
     transfer any principal amount to any Bank as provided above, then
     Agent shall promptly direct such principal amount by wire transfer to
     such Bank.

          (g)    SHARING OF PAYMENTS, ETC. - If any Bank shall obtain any
     payment (whether voluntary, involuntary, or otherwise) on account of
     the Loans, (including, without limitation, any set-off) which is in
     excess of its Pro Rata Part of payments on either of the Loans, as the
     case may be, obtained by all Banks, such Bank shall purchase from the
     other Banks such participation as shall be necessary to cause such
     purchasing Bank to share the excess payment pro rata with each of
     them; provided that, if all or any portion of such excess payment is
     thereafter recovered from such purchasing Bank, the purchase shall be
     rescinded and the purchase price restored to the extent of the
     recovery.  The Borrowers agree that any Bank so purchasing a
     participation from another Bank pursuant to this Section may, to the
     fullest extent permitted by law, exercise all of its rights of payment
     (including the right of offset) with respect to such participation as
     fully as if such Bank were the direct creditor of the Borrowers in the
     amount of such participation.

          (h)    NON-RECEIPT OF FUNDS BY THE AGENT - Unless the Agent shall
     have been notified by a Bank or the Borrowers (the "Payor") prior to
     the date on which such Bank is to make payment to the Agent of the
     proceeds of a Loan to be made by it hereunder or the Borrowers are to
     make a payment to the Agent for the account of one or more of the
     Banks, as the case may be (such payment being herein called the
     "Required Payment"), which notice shall be effective upon receipt,
     that the Payor does not intend to make the Required Payment to the
     Agent, the Agent may assume that the Required Payment has been made
     and may, in reliance upon such 


                                    -18-



     assumption (but shall not be required to), make the amount thereof 
     available to the intended recipient on such date and, if the Payor has 
     not in fact made the Required Payment to the Agent, the recipient of 
     such payment shall, on demand, pay to the Agent the amount made 
     available to it together with interest thereon in respect of the period 
     commencing on the date such amount was made available by the Agent until 
     the date the Agent recovers such amount at the rate applicable to such 
     portion of the applicable Loan.

          (i)    CAPITAL ADEQUACY - If either (i) the introduction or
     implementation of or the compliance with or any change in or in the
     interpretation of any law, rule or regulation or (ii) the introduction
     or implementation of or the compliance with any mandatory request,
     directive or guideline from any central bank or other governmental
     authority (whether or not having the force of law) affects or would
     affect the amount of capital required or expected to be maintained by
     any Bank or any corporation controlling any Bank as a result of
     maintaining its Pro Rata Part of the Revolving Commitment, then within
     fifteen (15) days after demand by such Bank, the Borrowers will pay to
     such Bank, from time to time as specified by such Bank, such
     additional amount or amounts which such Bank shall reasonably
     determine to be appropriate to compensate such Bank or any corporation
     controlling such Bank in light of such circumstances, to the extent
     that such Bank reasonably determines that the amount of any such
     capital would be increased, or the rate of return on any such capital
     would be reduced in whole or in part, based on the existence of the
     amount of the Loans or such Bank's Revolving Commitment under this
     Agreement; provided, however, that to the extent such notice is given
     by any such Bank more than 180 days after the occurrence of the event
     giving rise to the additional costs of the type described in this
     Section, such Bank shall not be entitled to compensation pursuant to
     this Section for any amounts incurred or accruing prior to the date
     180 days before the giving of such notice, except to the extent such
     law, rule, regulation, request, directive or guideline shall have been
     given retroactive effective affecting a period beginning more than 180
     days prior to such notice.

     4.   INTEREST RATES.

          (a)    OPTIONS.

                 (i)   PRIME RATE LOANS.  On Prime Rate Loans the Borrowers
          agree to pay interest on the Notes calculated on the basis of the
          actual days elapsed in a year consisting of 360 days with respect
          to the unpaid principal amount of each Prime Rate Loan from the
          date the proceeds thereof are advanced to Borrowers until
          maturity (whether by acceleration or otherwise), at a varying
          rate per annum equal to the lesser of (i) the Maximum Rate
          (defined herein), or (ii) the sum of the Prime Rate plus the
          Prime Rate Margin.  Subject to the provisions of this Agreement
          as to prepayment, the principal of the Notes representing Prime
          Rate Loans shall be payable as specified in Section 3(e) hereof
          and the interest in respect of each Prime Rate Loan shall be
          payable on each Interest Payment Date.  Past due principal and,
          to the extent permitted by law, past due interest in respect to
          each Prime Rate Loan, shall bear interest, payable on demand, at
          a rate per annum equal to the Default Rate.

                 (ii)  LIBOR LOANS.  On LIBOR Loans the Borrowers agree to pay
          interest calculated on the basis of a year consisting of 360 days
          with respect to the unpaid principal amount of each LIBOR Loan
          from the date the proceeds thereof are advanced to Borrowers
          until maturity (whether by acceleration or otherwise), at a
          varying rate per annum equal to the lesser of (i) the Maximum
          Rate, or (ii) the LIBOR Rate plus the LIBOR Margin.  Subject to
          the provisions of this Agreement with respect to prepayment, the
          principal of the Notes shall be payable as specified in Section
          3(e) hereof and the interest with respect to each LIBOR Loan
          shall be payable on each Interest Payment Date.  Past due
          principal and, to the extent permitted by law, past due interest
          shall bear interest, payable on demand, at a rate per annum equal
          to the Default Rate.  Upon three (3) London Business Days'
          written notice prior to the making by the Banks of any LIBOR Loan
          (in the case of the initial Interest Period therefor) or the
          expiration date of each succeeding Interest Period (in the case
          of subsequent Interest Periods therefor), Borrowers shall have
          the option, subject to compliance by Borrowers with all of the
          provisions of this Agreement, as long as no Event of Default
          exists, to specify whether the Interest Period commencing on any
          such date shall be a one (1), two (2), three (3) or six (6) month
          period.  If Agent shall not have received timely notice of a
          designation of such Interest Period as herein provided, Borrowers
          shall be deemed to have elected to convert all maturing LIBOR
          Loans to Prime Rate Loans.


                                    -20-



          (b)    INTEREST RATE DETERMINATION.  The Agent shall determine each
     interest rate applicable to the Loans hereunder in accordance with the
     provisions of this Agreement.  The Agent shall give prompt notice to
     the Borrowers and the Banks of each rate of interest so determined and
     its determination thereof shall be conclusive absent error.

          (c)    CONVERSION OPTION.  Borrowers may elect from time to time
     (i) to convert all or any part of its LIBOR Loans to Prime Rate Loans
     by giving Agent irrevocable notice of such election in writing prior
     to 10:00 a.m. (Oklahoma City, Oklahoma time) on the conversion date
     and such conversion shall be made on the requested conversion date,
     provided that any such conversion of a LIBOR Loan shall only be made
     on the last day of the LIBOR Interest Period with respect thereof,
     (ii) to convert all or any part of its Prime Rate Loans to LIBOR Loans
     by giving the Agent irrevocable written notice of such election three
     (3) London Business Days prior to the proposed conversion and such
     conversion shall be made on the requested conversion date or, if such
     requested conversion date is not a London Business Day or a Business
     Day, as the case may be, on the next succeeding London Business Day or
     Business Day, as the case may be.  Any such conversion shall not be
     deemed to be a prepayment of any of the loans for purposes of this
     Agreement or the Notes.

          (d)    RECOUPMENT.  If at any time the applicable rate of interest
     selected pursuant to Sections 4(a)(i) or 4(a)(ii) above shall exceed
     the Maximum Rate, thereby causing the interest on the Notes to be
     limited to the Maximum Rate, then any subsequent reduction in the
     interest rate so selected or subsequently selected shall not reduce
     the rate of interest on the Notes below the Maximum Rate until the
     total amount of interest accrued on the Note equals the amount of
     interest which would have accrued on the Notes if the rate or rates
     selected pursuant to Sections 4(a)(i) or (ii), as the case may be, had
     at all times been in effect.

     5.   CHANGE OF CIRCUMSTANCES.

          (a)    UNAVAILABILITY OF FUNDS OR INADEQUACY OF PRICING.  In the
     event that, in connection with any proposed LIBOR Loan, the Agent
     determines, which determination shall, absent manifest error, be
     final, conclusive and binding upon all parties, due to changes in
     circumstances since the date hereof, adequate and fair means do not
     exist for determining the LIBOR Rate or such rate will not accurately
     reflect the costs to the Banks of funding LIBOR Loans for such LIBOR
     Interest Period, the Agent shall give notice of such determination to
     the Borrowers and the Banks, whereupon, until the Agent notifies the
     Borrowers and the Banks that the circumstances giving rise to such
     suspension no longer exist, the obligations of the Banks to make,
     continue or convert Loans into LIBOR Loans shall be suspended, and all
     loans to Borrowers shall be Prime Rate Loans during the period of


                                    -21-



     suspension.

          (b)    CHANGE IN LAWS.  If at any time any new law or any change in
     existing laws or in the interpretation of any new or existing laws
     shall make it unlawful for any Bank to make or continue to maintain or
     fund LIBOR Loans hereunder, then such Bank shall promptly notify
     Borrowers in writing and such Bank's obligation to make, continue or
     convert Loans into LIBOR Loans under this Agreement shall be suspended
     until it is no longer unlawful for such Bank to make or maintain LIBOR
     Loans.  Upon receipt of such notice, Borrowers shall either repay the
     outstanding LIBOR Loans owed to the Banks, without penalty, on the
     last day of the current Interest Periods (or, if any Bank may not
     lawfully continue to maintain and fund such LIBOR Loans, immediately),
     or Borrowers may convert such LIBOR Loans at such appropriate time to
     Prime Rate Loans.

          (c)    INCREASED COST OR REDUCED RETURN.

                 (i)   If, after the date hereof, the adoption of any
          applicable law, rule, or regulation, or any change in any
          applicable law, rule, or regulation, or any change in the
          interpretation or administration thereof by any governmental
          authority, central bank, or comparable agency charged with the
          interpretation or administration thereof, or compliance by any
          Bank with any request or directive (whether or not having the
          force of law) of any such governmental authority, central bank,
          or comparable agency:

                       (A)  shall subject such Bank to any tax, duty, or other
                   charge with respect to any LIBOR Loans, its Notes, or its
                   obligation to make LIBOR Loans, or change the basis of
                   taxation of any amounts payable to such Bank under this
                   Agreement or its Notes in respect of any LIBOR Loans (other
                   than franchise taxes and taxes imposed on the overall net
                   income of such Bank);

                       (B)  shall impose, modify, or deem applicable any
                   reserve, special deposit, assessment, or similar requirement
                   (other than reserve requirements, if any, taken into account
                   in the determination of the LIBOR Rate) relating to any
                   extensions of credit or other assets of, or any deposits
                   with or other liabilities or commitments of, such Bank,
                   including the Revolving Commitment of such Bank hereunder;
                   or

                       (C)  shall impose on such Bank or on the London
                   interbank market any other condition affecting this
                   Agreement or its Notes or any of such extensions of credit
                   or liabilities or commitments;


                                    -22-



          and the result of any of the foregoing is to increase the cost to
          such Bank of making, converting into, continuing, or maintaining
          any LIBOR Loans or to reduce any sum received or receivable by
          such Bank under this Agreement or its Notes with respect to any
          LIBOR Loans, then Borrowers shall pay to such Bank on demand
          such amount or amounts as will compensate such Bank for such
          increased cost or reduction.  If any Bank requests compensation
          by Borrowers under this Section 5(c), Borrowers may, by notice to
          such Bank (with a copy to Agent), suspend the obligation of such
          Bank to make or continue LIBOR Loans, or to convert all or part
          of the Prime Rate Loan owing to such Bank to LIBOR Loans, until
          the event or condition giving rise to such request ceases to be
          in effect (in which case the provisions of Section 5(c) shall be
          applicable); PROVIDED that such suspension shall not affect the
          right of such Bank to receive the compensation so requested.

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

                    (iii) Each Bank shall promptly notify Borrowers and
          Agent of any event of which it has knowledge, occurring after the
          date hereof, which will entitle such Bank to compensation
          pursuant to this Section 5(c) will designate a separate lending
          office, if applicable, if such designation will avoid the need
          for, or reduce the amount of, such compensation and will not, in
          the judgment of such Bank, be otherwise disadvantageous to it. 
          Any Bank claiming compensation under this Section 5(c) shall
          furnish to Borrowers and Agent a statement setting forth the
          additional amount or amounts to be paid to it hereunder which
          shall be conclusive in the absence of manifest error.  In
          determining such amount, such Bank may use any reasonable
          averaging and attribution methods.


                                    -23-



                 (iv)  Any Bank giving notice to the Borrowers through the
          Agent, pursuant to Section 5(c) shall give to the Borrowers a
          statement signed by an officer of such Bank setting forth in
          reasonable detail the basis for, and the calculation of such
          additional cost, reduced payments or capital requirements, as the
          case may be, and the additional amounts required to compensate
          such Bank therefor.

                 (v)   Within five (5) Business Days after receipt by the
          Borrowers of any notice referred to in Section 5(c), the
          Borrowers shall pay to the Agent for the account of the Bank
          issuing such notice such additional amounts as are required to
          compensate such Bank for the increased cost, reduce payments or
          increase capital requirements identified therein, as the case may
          be; provided, that the Borrowers shall not be obligated to
          compensate such Bank for any increased costs, reduced payments or
          increased capital requirements to the extent that such Bank
          incurs the same prior to a date six (6) months before such Bank
          gives the required notice.

          (d)    DISCRETION OF BANK AS TO MANNER OF FUNDING.  Notwithstanding
     any provisions of this Agreement to the contrary, each Bank shall be
     entitled to fund and maintain its funding of all or any part of its
     Loans in any manner it sees fit, it being understood, however, that
     for the purposes of this Agreement all determinations hereunder shall
     be made as if each  Bank had actually funded and maintained each LIBOR
     Loan through the purchase of deposits having a maturity corresponding
     to the last day of the LIBOR Interest Period applicable to such LIBOR
     Loan and bearing an interest rate to the applicable interest rate for
     such LIBOR Period.

          (e)    BREAKAGE FEES.   Without duplication under any other
     provision hereof, if any Bank incurs any loss, cost or expense
     (including, without limitation, any loss of profit and loss, cost,
     expense or premium reasonably incurred by reason of the liquidation or
     re-employment of deposits or other funds acquired by such Bank to fund
     or maintain any LIBOR Loan or the relending or reinvesting of such
     deposits or amounts paid or prepaid to the Banks) as a result of any
     of the following events other than any such occurrence as a result in
     the change of circumstances described in Sections 5(a) and (b):

                 (i)   any payment, prepayment or conversion of a LIBOR Loan
          on a date other than the last day of its LIBOR Interest Period
          (whether by acceleration, prepayment or otherwise);

                 (ii)  any failure to make a principal payment of a LIBOR Loan
          on the due date thereof; or 


                                    -24-



                 (iii) any failure by the Borrowers to borrow, continue,
          prepay or convert to a LIBOR Loan on the dates specified in a
          notice given pursuant to Section 2(b) or 4(c) hereof;

     then the Borrowers shall pay to such Bank such amount as will
     reimburse such Bank for such loss, cost or expense.  If any Bank makes
     such a claim for compensation, it shall furnish to Borrowers and Agent
     a statement setting forth the amount of such loss, cost or expense in
     reasonable detail (including an explanation of the basis for and the
     computation of such loss, cost or expense) and the amounts shown on
     such statement shall be conclusive and binding absent manifest error.

     6.   COLLATERAL SECURITY.

          (a)    PLEDGE OF COLLATERAL.  To secure the performance by
     Borrowers of their obligations hereunder, and under the Notes and
     Security Instruments, whether now or hereafter incurred, matured or
     unmatured, direct or contingent, joint or several, or joint and
     several, including extensions, modifications, renewals and increases
     thereof, and substitutions therefore, Borrowers have heretofore
     granted and assigned to Bank One-Oklahoma a first and prior lien on
     certain of their Oil and Gas Properties, certain related equipment,
     oil and gas inventory and the proceeds of the foregoing. 
     Contemporaneously with the execution of this Agreement and the Notes,
     the Borrowers shall grant and assign to Agent for the ratable benefit
     of the Banks a first and prior Lien on certain of its Oil and Gas
     Properties, certain related equipment, oil and gas inventory, certain
     bank accounts, the System, the Plant and proceeds of the foregoing. 
     The Liens held by Bank One-Oklahoma on the Oil and Gas Properties
     shall be assigned, as of the Effective Date, to the Agent for the
     ratable benefit of the Banks.  The Oil and Gas Properties heretofore
     and herewith mortgaged to the Agent shall represent not less than 90%
     of the Engineered Value (as hereinafter defined) of Borrowers' Oil and
     Gas Properties as of the Effective Date.  All Oil and Gas Properties
     and other collateral in which Borrowers have heretofore granted to
     Bank One-Oklahoma, or herewith grant or hereafter grant to Agent for
     the ratable benefit of the Banks a first and prior Lien (to the
     satisfaction of the Agent) in accordance with this Section 6, as such
     properties and interests are from time to time constituted, are
     hereinafter collectively called the "Collateral".

          (b)    DOCUMENTATION AND TITLE REVIEW.  The granting and assigning
     of such security interests and Liens by Borrowers shall be pursuant to
     Security Instruments in form and substance reasonably satisfactory to
     the Agent.  Concurrently with the delivery of each of the Security
     Instruments or within a reasonable time thereafter, Borrowers shall
     furnish to the Agent mortgage and title opinions and other title
     information satisfactory to Agent with respect to the title and Lien
     status of Borrowers' interests in not less than 80% of the Engineered
     Value of the Oil and Gas Properties covered by the Security
     Instruments as Agent shall 


                                    -25-



     have designated.  "Engineered Value" for this purpose shall mean future 
     net revenues discounted at the discount rate being used by the Agent as 
     of the date of any such determination utilizing the pricing parameters 
     used in the engineering report furnished to the Agent for the ratable 
     benefit of the Banks, pursuant to Sections 7 and 12 hereof.  Borrowers 
     will cause to be executed and delivered to the Agent, in the future, 
     additional Security Instruments if the Agent reasonably deems such are 
     necessary to insure perfection or maintenance of Banks' security 
     interests and Liens in the Collateral or any part thereof.

          (c)    LETTERS IN LIEU OF TRANSFER ORDERS.  The Borrowers shall
     provide the Agent for the benefit of the Banks, undated letters in
     lieu of transfer orders, in form and substance satisfactory to Agent,
     from the Borrowers to each purchaser of hydrocarbons and disburser
     proceeds of hydrocarbons from and attributable to the Oil and Gas
     Properties, together with additional letters with addresses left blank
     authorizing and directing the addressees to make future payments
     attributable to hydrocarbons from the Oil and Gas Properties directly
     to the Agent for the benefit of the Banks.  The Banks agree that none
     of the letters in lieu of transfer orders provided by the Borrowers
     pursuant to this Section 6(c) will be sent to the address prior to the
     occurrence of an Event of Default, at which time the Agent may, at its
     option and in addition to the exercise of any of its other rights and
     remedies, send any and all of such letters to such addressees;
     provided, however, that upon the occurrence of an Event of Default
     other than those specified in Sections 14(f) and (g), the Agent shall
     not send any or all of such letters until the applicable period to
     cure, if any, such Default has lapsed without such Default being
     cured.  Borrowers hereby designate the Agent as its agent and
     attorney-in-fact, to act in its name, place and stead for the purpose
     of completing and delivering any and all letters in lieu of transfer
     orders delivered by the Borrowers to the Agent for the benefit of the
     Banks pursuant to Sections 6(c) and 11(a)(x) hereof, including,
     without limitation, completing any blanks contained in such letters
     and attaching exhibits thereto describing the relevant Collateral. 
     Borrowers hereby ratify and confirm all that the Agent shall lawfully
     do or cause to be done by virtue of this power of attorney and the
     rights granted with respect to such power of attorney.  This power of
     attorney is coupled with the interests of the Agent in the Collateral,
     shall commence and be in full force and effect as of the Effective
     Date and shall remain in full force and effect and shall be
     irrevocable until the obligations, if any, of the Agent hereunder have
     terminated and the full satisfaction of all obligations due hereunder
     or under the Notes.  The powers conferred on Agent by this appointment
     may only be exercised by the Agent by execution by any Person who, at
     the time of exercise, is an officer of the Agent, and are solely to
     protect the interests of the Agent and the Banks under the Loan
     Documents and shall not impose any duty upon the Agent to exercise any
     such powers.  The Agent shall be accountable only for amounts that it
     actually receives or has expressly directed that others receive as a
     result of the exercise of such powers and shall not be responsible to
     the Borrowers, or any other Person for 


                                    -26-



     any act or failure to act with respect to such powers, except for gross
     negligence or willful misconduct.

     7.   BORROWING BASE.

          (a)    INITIAL BORROWING BASE. At the Effective Date, the Borrowing
     Base shall be $175,000,000.00.

          (b)    SUBSEQUENT DETERMINATIONS OF BORROWING BASE.  Subsequent
     determinations of the Borrowing Base shall be made by the Banks at
     least semi-annually on May 1 and November 1 of each year beginning
     November 1, 1998 or as Unscheduled Redeterminations.  In connection
     with, and as of, each determination of the Borrowing Base, the Banks
     shall also redetermine the Monthly Commitment Reduction.  The
     Borrowers shall furnish to the Banks as soon as possible but in any
     event no later than April 1 of each year, beginning April 1, 1999,
     with an engineering report in form and substance satisfactory to the
     Agent prepared by an independent petroleum engineering acceptable to
     Agent covering the Oil and Gas Properties utilizing economic and
     pricing parameters used by Agent as established from time to time,
     together with such other information concerning the value of the Oil
     and Gas Properties as the Agent shall deem necessary to determine the
     value of the Oil and Gas Properties.  By October 1 of each year, or
     within thirty (30) days after either (i) receipt of notice from Agent
     that the Banks require an Unscheduled Redetermination, or (ii) the
     Borrowers give notice to Agent of their desire to have an Unscheduled
     Redetermination performed, the Borrowers shall furnish to the Banks an
     engineering report in form and substance satisfactory to Agent
     prepared by Borrowers' in-house engineering staff valuing the Oil and
     Gas Properties utilizing economic and pricing parameters used by the
     Agent as established from time to time, together with such other
     information, reports and data concerning the value of the Oil and Gas
     Properties as Agent shall deem reasonably necessary to determine the
     value of such Oil and Gas Properties.  Agent shall by notice to the
     Borrowers no later than May 1 and November 1 of each year, or within a
     reasonable time thereafter (herein called the "Determination Date"),
     notify the Borrowers of the designation by the Banks of the new
     Borrowing Base and Monthly Commitment Reduction for the period
     beginning on such Determination Date and continuing until, but not
     including, the next Determination Date.  If an Unscheduled
     Redetermination is made by the Banks, the Agent shall notify the
     Borrowers within a reasonable time after receipt of all requested
     information of the new Borrowing Base and Monthly Commitment
     Reduction, and such new Borrowing Base and Monthly Commitment
     Reduction shall continue until the next Determination Date.  If the
     Borrowers do not furnish all such information, reports and data by any
     date specified in this Section 7(b), the Banks may nonetheless
     designate the Borrowing Base and Monthly Commitment Reduction at any
     amounts which the Banks in their discretion determine and may
     redesignate the Borrowing Base and Monthly 


                                    -27-



     Commitment Reduction from time to time thereafter until the Banks 
     receive all such information, reports and data, whereupon the Banks 
     shall designate a new Borrowing Base and Monthly Commitment Reduction as 
     described above.  Each Bank shall determine the amount of the Borrowing 
     Base and Monthly Commitment Reduction based upon the loan collateral 
     value which such Bank in its discretion (using such methodology, 
     assumptions and discounts rates as such Bank customarily uses in 
     assigning collateral value to oil and gas properties, oil and gas 
     gathering systems, gas processing and plant operations) assigns to such 
     Oil and Gas Properties and other Collateral of the Borrowers at the time 
     in question and based upon such other credit factors consistently 
     applied (including, without limitation, the assets, liabilities, cash 
     flow, business, properties, prospects, management and ownership of the 
     Borrowers and their affiliates) as such Bank customarily considers in 
     evaluating similar oil and gas credits, but such Bank in its discretion 
     shall not be required to give any additional positive value to any Oil 
     and Gas Property over the current economic and pricing parameters used 
     by such Bank for such Determination Date which additional value is 
     derived directly from a hedging, forward sale or swap agreement covering 
     such Oil and Gas Property as of the date of such determination.  All 
     determinations or Unscheduled Redeterminations of the Borrowing Base and 
     the Monthly Commitment Reduction require the approval of Majority Banks; 
     provided, however, that notwithstanding anything to the contrary herein, 
     the amount of the Borrowing Base may not be increased, nor may the 
     Monthly Commitment Reduction be reduced, without the approval of all 
     Banks. If the Banks cannot otherwise agree on the Borrowing Base or the 
     Monthly Commitment Reduction, each Bank shall submit in writing to the 
     Agent its proposed Borrowing Base and Monthly Commitment Reduction and 
     the Borrowing Base and Monthly Commitment Reduction shall be set on the 
     basis of the weighted average of the Borrowing Bases and the weighted 
     average of the Monthly Commitment Reductions proposed by the Banks.  If 
     at any time any of the Oil and Gas Properties are sold, the Borrowing 
     Base then in effect shall automatically be reduced by a sum equal to the 
     amount of prepayment required to be made pursuant to Section 12(r) 
     hereof.  The Borrowing Base shall be additionally reduced from time to 
     time pursuant to the provisions of Sections 2(e) and 2(f) hereof.  It is 
     expressly understood that the Banks have no obligation to designate the 
     Borrowing Base or the Monthly Commitment Reduction at any particular 
     amounts, except in the exercise of their discretion, whether in relation 
     to the Revolving Commitment or otherwise.  Provided, however, that the 
     Banks shall not have the obligation to designate a Borrowing Base in an 
     amount in excess of the Revolving Commitment or its legal or internal 
     lending limits.  Upon the issuance of any public note issue permitted 
     pursuant to Section 13(f)(iv) hereof, the Banks shall have the right to 
     perform an Unscheduled Redetermination of the Borrowing Base.


                                    -28-



     8.   FEES.

          (a)    UNUSED COMMITMENT FEE.  The Borrowers shall pay to Agent for
     the ratable benefit of the Banks an unused commitment fee (the "Unused
     Commitment Fee") equivalent to the Unused Fee Rate times the
     unadvanced amount of the Revolving Commitment (calculated on a daily
     basis).  The Unused Commitment Fee shall be payable in arrears on the
     last Business Day of each calendar quarter beginning June 30, 1998
     with the final fee payment due on the Maturity Date for any period
     then ending for which the Unused Commitment Fee shall not have been
     theretofore paid.  In the event the Revolving Commitment terminates on
     any date prior to the end of any such monthly period, the Borrowers
     shall pay to the Agent for the ratable benefit of the Banks, on the
     date of such termination, the total Unused Commitment Fee due for the
     period in which such termination occurs.

          (b)    THE LETTER OF CREDIT FEE.  Borrowers shall pay to the Agent
     the Letter of Credit fees required above in Section 2(d).

          (c)    AGENCY FEES.  The Borrowers shall pay to the Agent certain
     fees for acting as Agent hereunder in amounts to be negotiated between
     the Borrowers and the Agent.

          (d)    OTHER FEES. The Borrowers shall pay on the Effective Date
     the additional fees provided for in the Engagement Letter dated
     April 20, 1998 by and among Resources, Bank One-Oklahoma and Bank One
     Capital Markets, Inc.

     9.   PREPAYMENTS.

          (a)    VOLUNTARY PREPAYMENTS.  Subject to the provisions of
     Section 5(e) hereof, the Borrowers may at any time and from time to
     time, without penalty or premium, prepay the Notes, in whole or in
     part.  Each such prepayment shall be made on at least three (3) London
     Business Days' notice to Agent in the case of LIBOR Loan Tranches and
     without notice in the case of Prime Rate Loan Tranches and shall be in
     a minimum amount of $500,000 or any larger multiple thereof or the
     unpaid balance on the Notes, whichever is less, plus accrued interest
     thereon to the date of prepayment.

          (b)    MANDATORY PREPAYMENT FOR BORROWING BASE DEFICIENCY.  In the
     event the Total Outstandings ever exceed the Borrowing Base as
     determined by Banks pursuant to Section 7(b) hereof, the Borrowers
     shall, within thirty (30) days after notification from the Agent,
     either (A) by instruments reasonably satisfactory in form and
     substance to the Bank, provide the Agent with collateral with value
     and quality in amounts satisfactory to all of the Banks in their
     discretion in order to increase the Borrowing Base by an amount at
     least equal to such excess, or (B) 


                                    -29-



     prepay, without premium or penalty, the principal amount of the 
     Revolving Notes in an amount at least equal to such excess plus accrued 
     interest thereon to the date of prepayment.  If the Total Outstandings 
     ever exceed the Revolving Commitment as a result of a Monthly Commitment 
     Reduction or any other required reduction in the Revolving Commitment, 
     then in such event, Borrowers shall immediately prepay the principal 
     amount of the Revolving Notes in an amount at least equal to such excess 
     plus accrued interest to the date of prepayment.

     10.  REPRESENTATIONS AND WARRANTIES.  In order to induce the Banks to
enter into this Agreement, the Borrowers hereby, jointly and severally,
represent and warrant to the Banks (which representations and warranties will
survive the delivery of the Notes) that:

          (a)    CREATION AND EXISTENCE.  Borrowers are each a corporation
     duly organized, validly existing and in good standing under the laws
     of the jurisdiction in which it was formed and is duly qualified in
     all jurisdictions wherein failure to qualify may result in a Material
     Adverse Effect.  Borrowers each have all power and authority to own
     its properties and assets and to transact the business in which it is
     engaged.

          (b)    POWER AND AUTHORITY.  Borrowers are each duly authorized and
     empowered to create and issue the Notes; and Borrowers are duly
     authorized and empowered to execute, deliver and perform their
     respective Loan Documents, including this Agreement; and all
     corporation action on each Borrower's part requisite for the due
     creation and issuance of the Notes and for the due execution, delivery
     and performance of the Loan Documents, including this Agreement, has
     been duly and effectively taken.  Each Support Party is duly
     authorized and empowered to execute, deliver and perform the
     respective Loan Documents to which they are a party, including the
     Subordination Agreement; and all action on each Support Party's part

     Documents has been duly and effectively taken.

          (c)    BINDING OBLIGATIONS.  This Agreement does, and the Notes and
     other Loan Documents upon their creation, issuance, execution and
     delivery will, constitute valid and binding obligations of Borrowers,
     enforceable in accordance with their respective terms (except that
     enforcement may be subject to applicable principles of equity and the
     effect of any applicable bankruptcy, insolvency, or similar debtor
     relief laws now or hereafter in effect and relating to or affecting
     the enforcement of creditors' rights generally). The Subordination 
     Agreement upon its creation, issuance, execution and delivery will
     constitute valid and binding obligations of each of the Support
     Parties, enforceable in accordance with their respective terms (except

     the effect of any applicable bankruptcy, insolvency, or similar debtor
     relief laws now or hereafter in effect and relating to or affecting
     the enforcement of 


                                    -30-



     creditors' rights generally).

          (d)    NO LEGAL BAR OR RESULTANT LIEN.  The Notes and the Loan
     Documents, including this Agreement, do not and will not, to the best
     of each Borrower's and each Support Party's knowledge violate any
     provisions of any contract, agreement, law, regulation, order,
     injunction, judgment, decree or writ to which any Borrower or any
     Support Party is  subject which could reasonable be expected to have a
     Material Adverse Effect, or result in the creation or imposition of
     any lien or other encumbrance upon any assets or properties of any
     Borrower or any Support Party, other than those contemplated by this
     Agreement.

          (e)    NO CONSENT.  The execution, delivery and performance by the
     Borrowers of the Notes and by the Borrowers and the Support Parties of
     their respective Loan Documents, including this Agreement, does not
     require the consent or approval of any other person or entity,
     including without limitation any regulatory authority or governmental
     body of the United States or any state thereof or any political
     subdivision of the United States or any state thereof except for
     (i) consents required for federal, state and, in some instances,
     private leases, right of ways and other conveyances or encumbrances of
     oil and gas leases, if any, all of which consents have been obtained
     by the Borrowers.

          (f)    FINANCIAL CONDITION.  The unaudited Financial Statements of
     Borrowers dated December 31, 1997, which have been delivered to Banks
     are complete and correct in all material respects, and fully and
     accurately reflect in all material respects the financial condition
     and results of the operations of the Borrowers on a consolidated basis
     as of the date or dates and for the period or periods stated.  No
     change has since occurred in the condition, financial or otherwise, of
     the Borrowers which is reasonably expected to have a Material Adverse
     Effect, except as disclosed to the Banks in Schedule "2" attached
     hereto.

          (g)    LIABILITIES.  Neither Borrower has any material
     (individually or in the aggregate) liability, direct or contingent,
     except as disclosed to the Banks in the Financial Statements or on
     Schedule "3" attached hereto.  No unusual or unduly burdensome
     restrictions, restraint, or hazard exists by contract, law or
     governmental regulation or otherwise relative to the business, assets
     or properties of Borrowers which is reasonably expected to have a
     Material Adverse Effect.

          (h)    LITIGATION.  Except as described in the Financial
     Statements, or as otherwise disclosed to the Banks in Schedule "4"
     attached hereto, there is no litigation, legal or administrative
     proceeding, investigation or other action of any nature pending or, to
     the knowledge of the officers of Borrowers threatened against or
     affecting Borrowers which involves the possibility of any judgment or
     liability not fully covered by insurance, and which is reasonably
     expected to have a Material 


                                    -31-



     Adverse Effect.

          (i)    TAXES; GOVERNMENTAL CHARGES.  Borrowers have each filed all
     tax returns and reports required to be filed and has paid all taxes,
     assessments, fees and other governmental charges levied upon them or
     their assets, properties or income which are due and payable,
     including interest and penalties, the failure of which to pay could
     reasonably be expected to have a Material Adverse Effect, except such
     as are being contested in good faith by appropriate proceedings and
     for which adequate reserves for the payment thereof as required by
     GAAP has been provided and levy and execution thereon have been stayed
     and continue to be stayed.

          (j)    TITLES, ETC.  Borrowers each have defensible title to all of
     its respective assets, including without limitation, the Oil and Gas
     Properties, the Plants and the Systems, free and clear of all liens or
     other encumbrances except Permitted Liens, except such failure or
     failures of title which in the aggregate could not reasonably be
     expected to reduce the Borrowing Base by more than $500,000.

          (k)    DEFAULTS.  Neither Borrower is in default and no event or
     circumstance has occurred which, but for the passage of time or the
     giving of notice, or both, would constitute a default under any loan
     or credit agreement, indenture, mortgage, deed of trust, security
     agreement or other agreement or instrument to which either Borrower is
     a party in any respect that would be reasonably expected to have a
     Material Adverse Effect.  No Event of Default hereunder has occurred
     and is continuing.

          (l)    CASUALTIES; TAKING OF PROPERTIES.  Since the dates of the
     latest Financial Statements of the Borrowers delivered to Banks,
     neither the business nor the assets or properties of Borrowers have
     been affected (to the extent it is reasonably likely to cause a
     Material Adverse Effect), 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 domestic or
     foreign government or any agency thereof, riot, activities of armed
     forces or acts of God or of any public enemy.

          (m)    USE OF PROCEEDS; MARGIN STOCK.  The proceeds of the
     Revolving Commitment may be used by the Borrowers for the purposes of
     (i) refinancing existing debt owed to Bank One-Oklahoma,
     (ii) acquisition, exploration and development of oil and gas
     properties or entities owning oil and gas properties, (iii) Letters of
     Credit, and (iv) general corporate purposes.  Neither Borrower is
     engaged principally or as one of its important activities in the
     business of extending credit for the purpose of purchasing or carrying
     any "margin stock" as defined in Regulation U of the Board of
     Governors of the Federal Reserve System (12 C.F.R. Part 221), or for
     the purpose of reducing or retiring any indebtedness which was


                                    -32-



     originally incurred to purchase or carry a margin stock or for any
     other purpose which might constitute this transaction a "purpose
     credit" within the meaning of said Regulation G or U.

          Neither Borrower nor any person or entity acting on behalf of
     Borrowers has taken or will take any action which might cause the
     loans hereunder or any of the Loan Documents, including this
     Agreement, to violate Regulation G or U or any other regulation of the
     Board of Governors of the Federal Reserve System or to violate the
     Securities Exchange Act of 1934 or any rule or regulation thereunder,
     in each case as now in effect or as the same may hereafter be in
     effect.

          (n)    LOCATION OF BUSINESS AND OFFICES.  The principal place of
     business and chief executive offices of the Borrowers are located at
     the address stated in Section 17 hereof.

          (o)    COMPLIANCE WITH THE LAW.  To the best of either Borrower's
     knowledge, neither Borrower:

                 (i)  is in violation of any law, judgment, decree, order,
          ordinance, or governmental rule or regulation to which either
          Borrower, or any of its assets or properties are subject; or 

                 (ii) has failed to obtain any license, permit, franchise or
          other governmental authorization necessary to the ownership of
          any of its assets or properties or the conduct of its business;

     which violation or failure is reasonably expected to have a Material
     Adverse Effect.

          (p)    NO MATERIAL MISSTATEMENTS.  No information, exhibit or
     report furnished by Borrowers to the Banks 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.

          (q)    ERISA.  Borrowers are each in compliance in all material
     respects with the applicable provisions of ERISA, and no "reportable
     event", as such term is defined in Section 403 of ERISA, has occurred
     with respect to any Plan of Borrowers.

          (r)    PUBLIC UTILITY HOLDING COMPANY ACT.  Neither Borrower is a
     "holding company", or "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 


                                    -33-



     Company Act of 1935, as amended.

          (s)    SUBSIDIARIES.  All of the Borrowers' Subsidiaries are listed
     on Schedule "5" hereto.

          (t)    ENVIRONMENTAL MATTERS.  Except as disclosed on Schedule "6",
     neither Borrower (i) has received notice or otherwise learned of any
     Environmental Liability which would be reasonably likely to
     individually or in the aggregate have a Material Adverse Effect
     arising in connection with (A) any non-compliance with or violation of
     the requirements of any Environmental Law or (B) the release or
     threatened release of any toxic or hazardous waste into the
     environment, (ii) has received notice of any threatened or actual
     liability in connection with the release or notice of any threatened
     release of any toxic or hazardous waste into the environment which
     would be reasonably likely to individually or in the aggregate have a
     Material Adverse Effect or (iii) has received notice or otherwise
     learned of any federal or state investigation evaluating whether any
     remedial action is needed to respond to a release or threatened
     release of any toxic or hazardous waste into the environment for which
     either Borrower is or may be liable which may reasonably be expected
     to result in a Material Adverse Effect.

          (u)    LIENS.  Except (i) as disclosed on Schedule "1" hereto and
     (ii) for Permitted Liens, the assets and properties of the Borrowers
     are free and clear of all liens and encumbrances.

          (v)    GAS CONTRACTS.  Except as described on Schedule "7" hereto,
     the Borrowers (a) are not obligated in any material respect by virtue
     of any prepayment made under any contract containing a "take-or-pay,",
     "recoupment," or "prepayment" provision or under any similar agreement
     to deliver hydrocarbons produced from or allocated to any of the Oil
     and Gas Properties at some future date without receiving full payment
     therefor at the time of delivery, and (b) has not produced gas, in any
     material amount, subject to, and is not, nor are any of the Oil and
     Gas Properties, subject to balancing rights of third parties or
     subject to balancing duties under governmental requirements, except as
     to such matters for which the Borrowers have established monetary
     reserves adequate in an amount to satisfy such obligations and has
     segregated such reserves from other accounts or the Borrowers'
     balancing obligations in the aggregate would not reasonably be
     expected to have a Material Adverse Effect.

          (w)    YEAR 2000 COMPLIANCE.  The Borrowers have (i) initiated a
     review and assessment of all areas within each of theirs and their
     Subsidiaries' business and operations that could be adversely affected
     by the "Year 2000 Problem" (that is, the risk that computer
     applications used by the Borrowers or any of their Subsidiaries may be
     unable to recognize and perform properly date-sensitive functions
     involving 


                                    -34-



     certain dates prior to and any date after December 31, 1999), (ii) 
     developed a plan and timeline for addressing the Year 2000 Problem on a 
     timely basis, and (iii) to date, implemented that plan in accordance 
     with that timetable.  The Borrowers reasonably believe that all computer 
     applications that are material to their or any of their Subsidiaries' 
     business and operations will on a timely basis be able to perform 
     properly date-sensitive functions for all dates before and after January 
     1, 2000 (that is, be "Year 2000 Compliant"), except to the extent that a 
     failure to do so could not reasonably be expected to have Material 
     Adverse Effect.

          (x)    DELHI OAKDALE LATERAL SYSTEM. A portion of the Aline
     Gathering System is not owned by either Borrower, rather, it is leased
     pursuant to the Delhi Lease.  The primary term of the Delhi Lease has
     expired, however, the Borrowers' right to use the Delhi Oakdale
     Lateral System is renewed on a month-to-month basis.  The Delhi
     Oakdale Lateral System is not a critical portion of the Aline
     Gathering System.  The Delhi Oakdale Lateral System accounts for no
     more than two percent (2%) of the volume of hydrocarbons flowing
     through the Aline Gathering System.

          (y)    ALINE GATHERING SYSTEM.  At lease ninety percent (90%) of
     the hydrocarbons flowing through the Aline Gathering System originate
     from wells directly connected to the Aline Gathering System or flows
     through the Aline Gathering System prior to delivery to the Oklahoma
     Natural Gas Company's or other purchaser's system.

     deductible not to exceed amounts customary in the industry for similarly
     situated business and properties) of the property insured, and (iii) to
     provide for such other matters as the Agent may reasonably require.
     Additionally, the Borrowers shall at all times maintain adequate insurance

     good faith by appropriate legal proceedings or Permitted Liens.

          (o)       OPERATION OF PROPERTIES.  Except as provided in Subsection

     hydrocarbons and other minerals therefrom; provided, however, that the
     Borrowers shall have the right to contest in good faith by appropriate
     proceedings, the applicability or lawfulness of any such law, rule or
     regulation and pending such contest may defer compliance therewith, as
     long as such deferment shall not subject the properties or any part
     thereof to foreclosure or loss.

          (p)       COMPLIANCE WITH LEASES AND OTHER INSTRUMENTS.  The Borrowers
     will pay or cause to be paid and discharge all rentals, delay rentals,

     and do all other things necessary of Borrowers to keep unimpaired in
     all material respects the rights of Borrowers thereunder and to

     Borrowers to perpetuate or renew any oil and gas lease or other lease
     by payment of rental or delay rental or by commencement or
     continuation of operations nor to prevent Borrowers from abandoning or
     releasing any oil and gas lease or other lease or well thereon when,
     in any of such events, in the opinion of Borrowers exercised in good
     faith, it is not in the best interest of the Borrowers to perpetuate
     the same.

          (q)       CERTAIN ADDITIONAL ASSURANCES REGARDING MAINTENANCE AND
     OPERATIONS OF PROPERTIES.  With respect to those Oil and Gas
     Properties which are being operated by operators other than the
     Borrowers, the Borrowers shall not be obligated to perform any
     undertakings contemplated by the covenants and agreement contained in
     Subsections 12(o) or 12(p) hereof which are performable only by such
     operators and are beyond the control of the Borrowers; however, the

                                     -43-


     Borrowers agree to promptly take all reasonable actions available
     under any operating agreements or otherwise to bring about the
     performance of any such material undertakings required to be performed
     thereunder.

          (r)       SALE OF CERTAIN ASSETS/PREPAYMENT OF PROCEEDS.  Except with
     respect to sales permitted under Section 13(a)(ii)(C) hereof, the
     Borrowers will immediately pay over to the Agent for the ratable
     benefit of the Banks as a prepayment of principal on the Revolving
     Notes, an amount equal to 100% of the Release Price received by
     Borrowers from the sale of the Oil and Gas Properties, which sale has
     been approved in advance by the Majority Banks.  The term "Release
     Price" as used herein shall mean a price determined by the Majority
     Banks in their discretion based upon the loan collateral value which
     such Banks in their discretion (using such methodology, assumptions
     and discounts rates as such Banks customarily use in assigning
     collateral value to oil and gas properties, oil and gas gathering
     systems, gas processing and plant operations) assign to such Oil and
     Gas Properties at the time in question.  Any such prepayment of
     principal on the Revolving Notes required by this Section 12(r), shall
     not be in lieu of, but shall be in addition to, any Monthly Commitment
     Reduction or any mandatory prepayment of principal required to be paid
     pursuant to Section 9(b) hereof.

          (s)       TITLE MATTERS.  Within thirty (30) days after the Effective
     Date with respect to the Oil and Gas Properties listed on Schedule "8"
     hereto, furnish Agent with title opinions and/or title information
     reasonably satisfactory to Agent showing defensible title of the
     applicable Borrower to such Oil and Gas Properties subject only to the
     Permitted Liens.  As to any Oil and Gas Properties hereafter mortgaged
     to Agent, Borrowers will promptly (but in no event more than thirty
     (30) days following such mortgaging), furnish Agent with title
     opinions and/or title information reasonably satisfactory to Agent
     covering a sufficient value of such Oil and Gas Properties to maintain
     the required level of title coverage at 72% of the Engineered Value of
     the total Oil and Gas Properties.  Said title information shall show
     defensible title of the applicable Borrower to such Oil and Gas
     Properties subject only to Permitted Liens.

          (t)       CURATIVE MATTERS.  Within sixty (60) days after the
     Effective Date with respect to matters listed on Schedule "9" and,
     thereafter, within sixty (60) days after receipt by Borrowers from
     Agent or its counsel of written notice of title defects the Agent
     reasonably requires to be cured, Borrowers shall either (i) provide
     such curative information, in form and substance satisfactory to
     Agent, or (ii) substitute Oil and Gas Properties of value and quality
     satisfactory to the Agent for all of Oil and Gas Properties for which
     such title curative was requested but upon which Borrowers elected not
     to provide such title curative information, and, within sixty (60)
     days of such substitution, provide title opinions or title information
     satisfactory to the Agent covering the Oil and Gas Properties so
     substituted.

                                     -44-


          (u)       CHANGE OF PRINCIPAL PLACE OF BUSINESS.  Borrowers shall give
     Agent at least thirty (30) days prior written notice of its intention
     to move its principal place of business from the address set forth in
     Section 17 hereof.

          (v)       OPERATING ACCOUNTS.  Borrowers shall establish and maintain
     with Agent one or more operating accounts (the "Operating Accounts"),
     the maintenance of each of which shall be subject to such rules and
     regulations as the Agent shall from time to time specify.  Such
     Operating Accounts shall be the primary oil and gas operating account
     of the Borrowers and such accounts shall be maintained with the Agent
     until all amounts due hereunder and under the Notes have been paid in
     full.  The Borrowers hereby grant a security interest to Banks in and
     to the Operating Accounts and all checks, drafts and other items ever
     received by any Bank for deposit therein.  If any Event of Default
     shall occur and be continuing, Agent shall have the immediate right,
     without prior notice or demand, to take and apply against the
     Borrowers' obligations hereunder any and all funds legally and
     beneficially owned by the Borrowers then or thereafter on deposit in
     the Operating Accounts for the ratable benefit of the Banks.

          (w)       YEAR 2000 COMPLIANCE.  Borrowers will promptly notify the
     Agent in the event the Borrowers discover or determine that any
     computer application that is material to either of them or to any of
     their Subsidiaries' business and operations will not be Year 2000
     Compliant on a timely basis, except to the extent that such failure
     could not reasonably be expected to have a Material Adverse Effect.

          (x)       ADDITIONAL PROPERTY.  Borrowers shall, within five (5) days
     after receiving a written request thereof from Agent, execute and
     deliver, or cause to be executed and delivered, such mortgages, deeds
     of trust, instruments, security agreements, assignments, financing
     statements, and other documents, as may be reasonably necessary in the
     opinion of Agent and Agent's counsel, to grant Agent valid first
     mortgage liens and first, prior and perfected security interests in
     and to additional oil and gas properties of such value as Agent shall
     deem necessary to provide additional security for full and prompt
     payment of all amounts owed hereunder and under the Notes.  At Agent's
     option and on request therefor, Borrowers will furnish Agent title
     opinions covering such additional oil and gas properties prepared by
     counsel not employed by Borrowers (or such other evidence to
     Borrowers' ownership thereof and their revenue interest therein or
     attributable thereto as Agent may reasonably require), in form and
     substance satisfactory to Agent, subject only to title defects
     approved by Agent.

          (y)       ALINE GATHERING SYSTEM.  Substantially maintain the current
     levels of throughput from wells directly connected to the Aline
     Gathering System.

                                     -45-


          (z)       LETTERS IN LIEU OF TRANSFER ORDERS.  The Borrowers shall
     promptly upon the reasonable request of the Agent, at any time and
     from time to time and without limitation on the rights of Agent in
     accordance with Section 6(c) hereof, execute such letters in lieu of
     transfer orders, in addition to the letters signed by the Borrowers
     and delivered to the Agent in satisfaction of the conditions set forth
     in Sections 6(c) and 11(a)(x) hereof, as are necessary or appropriate
     to transfer and deliver to the Agent for the benefit of the Banks
     proceeds from or attributable to any Oil and Gas Property or other
     Collateral; provided, however, that such letters shall only be
     delivered to the addressees thereof in accordance with the provision
     of Section 6(c) hereof.

          (aa)      DIVISION ORDERS.  The Borrowers shall promptly upon request
     by the Agent at any time and from time to time following the
     occurrence of any Event of Default and without limitations on the
     rights of the Agent in accordance with Section 6(c) hereof, execute
     such division and/or transfer orders as are necessary or appropriate
     to transfer and deliver to the Agent for the ratable benefit of the
     Banks proceeds from the sale of hydrocarbon production from or
     attributable to any Oil and Gas Property; provided, however, that the
     Banks shall only send or deliver such division orders and/or transfer
     orders in accordance with Section 6(c) hereof.

          (bb)      TAKE OR PAY AGREEMENT.  The Borrowers shall, in connection
     with their delivery of the engineering reports required by Sections 7
     and 12 hereof, deliver to Agent copies of contracts or other
     agreements concerning "take or pay" and "prepayment", and provide
     notice of all gas balance liabilities of the Borrowers.

     13.  Negative Covenants.  A deviation from the provisions of this
Section 13 shall not constitute a Default or an Event of Default under this
Agreement if such deviation is consented to in writing by the required
percentage of the Banks prior to the date of deviation.  The Borrowers will
at all times comply with the covenants contained in this Section 13 from the
date hereof and for so long as the Revolving Commitment is in existence or
any amount is owed to the Agent or the Banks under this Agreement or the
other Loan Documents.

          (a)       NEGATIVE PLEDGE.  Neither Borrower shall without the prior
     written consent of the Banks:

                    (i)   create, incur, assume or permit to exist any Lien,
          security interest or other encumbrance on any of its assets or
          properties except Permitted Liens; or

                    (ii)  sell, lease, transfer or otherwise dispose of, in any
          fiscal year, any of its assets except for (A) sales, leases,
          transfers or other dispositions made in the ordinary course of
          Borrowers' oil and gas businesses, (B) sales made with the
          consent of Majority Banks which are made pursuant to, and

                                     -46-


          in full compliance with, Section 12(r) hereof; and (C) sales, leases
          or transfers or other dispositions made by Borrowers during any
          fiscal year, one or any series of transactions, the aggregate
          value of which does not exceed $5,000,000.00 in any such year if,
          and only if, such sale, lease, transfer or other disposition does
          not result in the occurrence of a Default or Event of Default;

          (b)       CURRENT RATIO. Borrowers shall not allow their ratio of
     consolidated Current Assets to consolidated Current Liabilities to be
     less than 1.0 to 1.0 as of the end of any fiscal quarter.

          (c)       RATIO OF DEBT TO MINIMUM TANGIBLE NET WORTH. The Borrowers
     will not allow their ratio of consolidated Debt to consolidated
     Tangible Net Worth to ever be greater than 3.25 to 1.0 as of the end
     of any fiscal quarter.

          (d)       MINIMUM DEBT SERVICE COVERAGE RATIO. Beginning with the
     calendar quarter ending September 30, 1998, the Borrowers will not
     allow their consolidated Debt Service Coverage Ratio to ever be less
     than 1.20 to 1.0.

          (e)       CONSOLIDATIONS AND MERGERS.  Neither Borrower will
     consolidate or merge with or into any other Person, except that either
     Borrower may merge with another Person if such Borrower is the
     surviving entity in such merger and if, after giving effect thereto,
     no Default or Event of Default shall have occurred and be continuing.

          (f)       DEBTS, GUARANTIES AND OTHER OBLIGATIONS.  Without the
     consent of Majority Banks, neither Borrower will incur, create, assume
     or in any manner become or be liable in respect of any indebtedness,
     nor will either Borrower guarantee or otherwise in any manner become
     or be liable in respect of any indebtedness, liabilities or other
     obligations of any other person or entity, whether by agreement to
     purchase the indebtedness of any other person or entity or agreement
     for the furnishing of funds to any other person or entity through the
     purchase or lease of goods, supplies or services (or by way of stock
     purchase, capital contribution, advance or loan) for the purpose of
     paying or discharging the indebtedness of any other person or entity,
     or otherwise, except that the foregoing restrictions shall not apply
     to:

                    (i)  the Notes and any renewal or increase thereof, or other
          indebtedness of the Borrowers heretofore disclosed to Banks in
          the Borrowers' Financial Statements or on Schedule "3" hereto; or

                    (ii) taxes, assessments or other government charges which
          are not yet due or are being contested in good faith by
          appropriate action

                                     -47-


          promptly initiated and diligently conducted, if such reserve as shall 
          be required by GAAP shall have been made therefor and levy and 
          execution thereon have been stayed and continue to be stayed; or 

                    (iii) indebtedness (other than in connection with a loan
          or lending transaction) incurred in the ordinary course of
          business, including, but not limited to indebtedness for
          drilling, completing, leasing and reworking oil and gas wells or
          the treatment, distribution, transportation of sale of production
          therefrom and loans or lending transactions in which the
          outstanding principal balance does not exceed $500,000 at any
          time and which does not result in the imposition of a Lien other
          than a Permitted Lien; or; or

                    (iv)  indebtedness issued pursuant to an indenture providing
          for the sale of notes to the public not exceeding the face amount
          of $200,000,000, which indebtedness (A) is expressly subordinated
          (to the satisfaction of Majority Banks) to all obligations owed
          the Banks hereunder and under the Notes, (B) is issued by the
          Borrowers or an Affiliate of the Borrowers, within one hundred
          eighty (180) days of the Effective Date, and (C) the net proceeds
          of which are used in part to repay or reduce the outstanding
          balance on the Notes, said indebtedness to be approved in advance
          by Majority Banks, which approval will not be unreasonably
          withheld; or

                    (v)   other indebtedness owed to Affiliates of Borrowers
          which is expressly made subordinate to the indebtedness owed
          hereunder and under the Notes, which subordination is approved in
          advance by Majority Banks, which approval will not be
          unreasonably withheld; or

                    (vi)  any renewals or extensions of (but not increases in)
          any of the foregoing.

          (g)       DIVIDENDS OR DISTRIBUTIONS.  Neither Borrower will declare,
     pay or make, whether in cash or property (excluding stock dividends),
     or set aside or apply any money or assets to pay or make any dividend
     or distribution during any fiscal year except the foregoing
     restriction shall not apply to (i) cash dividends paid by Resources to
     its shareholders in amounts equal to each such shareholders' allocable
     share of federal or state income taxes attributable to Resources
     taxable net income and (ii) dividends made by Gas to Resources. 
     Provided, however, that no dividend shall be made by either Borrower
     if an Event of Default has occurred and is continuing or would occur
     as a result of the making of such dividends.  Resources shall provide
     the Agent at least annually with sufficient information from which
     Agent can verify all shareholders' allocable share of such income
     taxes.

                                     -48-


          (h)       LOANS AND ADVANCES.  Neither Borrower shall make or permit
     to remain outstanding any loans or advances made by either Borrower to
     or in any person or entity, except that the foregoing restriction
     shall not apply to:

                    (i)   loans or advances to any person, the material details
          of which have been set forth in the Financial Statements of the
          Borrowers heretofore furnished to Banks; or

                    (iv)  loans or advances not to exceed $2,000,000 in the
          aggregate to Affiliates of the Borrowers.

          (i)       SALE OR DISCOUNT OF RECEIVABLES.  Neither Borrower will

     $250,000 in any fiscal year.

          (j)       NATURE OF BUSINESS.  Neither Borrower will permit any
     material change to be made in the character of its business as carried
     on at the date hereof.

          (k)       TRANSACTIONS WITH AFFILIATES.  Neither Borrower will enter
     into any transaction with any Affiliate (other than Borrower), except
     transactions upon terms that are no less favorable to it than would be
     obtained in a transaction negotiated at arm's length with an unrelated
     third party.

          (l)       HEDGING TRANSACTIONS.  Neither Borrower will enter into any
     transaction providing (i) for the hedging, forward sale, swap or any
     deviation thereof of crude oil or natural gas or other commodities, or
     (ii) for a swap, collar, floor, cap, option, corridor, or other
     contract which is intended to reduce or eliminate the risk of
     fluctuation in interest rates, as such terms are referred to in the
     capital markets, except the foregoing prohibitions shall not apply to
     (x) transactions consented to in writing by the Banks which are on
     terms acceptable to the Banks, or (y) Pre-Approved Contracts.  The
     term "Pre-Approved Contracts" as used herein shall mean any contract
     or agreement (i) to hedge, forward, sell or swap crude oil or natural
     gas or otherwise sell up to 50% of the Borrowers' monthly production
     forecast for all of Borrowers', proved and producing oil and gas
     properties for the period covered by the proposed hedging transaction,
     and (ii) with a maturity of twelve (12) months or less.

                                     -49-


          (m)       INVESTMENTS.  Neither Borrower shall make any investments in

          outstanding at any time.

          (n)       AMENDMENT TO ARTICLES OF INCORPORATION OR BYLAWS.  Neither
     Borrower will permit any amendment to, or any alteration of, its
     Articles of Incorporation or Bylaws, which amendment or alteration
     could reasonably be expected to have a Material Adverse Effect.

          (o)       LEASES.  With the exception of the lease agreement, as it
     currently exists, with Harold Hamm regarding The Continental Center
     North Building located in Enid, Oklahoma, the Borrowers will not enter
     into or agree to enter into, any rental or lease agreement resulting
     or which would result in aggregate rental or lease payments of the
     Borrowers exceeding $250,000 in the aggregate in any fiscal year of
     the Borrowers under all rental or lease agreement under which either
     Borrower is a lessee of the property or assets covered thereby;
     PROVIDED, HOWEVER, that the 

                                     -50-


     foregoing restriction shall not apply to oil, gas and mineral leases or 
     permits or similar agreements entered into in the ordinary course of 
     business or orders of any governmental authority adjudicating the rights 
     or pooling the interests of the owners of oil and gas properties or lease 
     agreements in effect as of the date hereof.

     14.  EVENTS OF DEFAULT.  Any one or more of the following events shall 
be considered an "Event of Default" as that term is used herein:

     principal of, and the interest on, the Notes, or any fee or any other
     indebtedness of the Borrowers incurred pursuant to this Agreement or

          (b)       Any representation or warranty made by Borrowers under this
     Agreement, or in any certificate or statement furnished or made to the
     Banks pursuant hereto, or in connection herewith, or in connection
     with any document furnished hereunder, shall prove to be untrue in any
     material respect as of the date on which such representation or
     warranty is made (or deemed made), or any representation, statement
     (including financial statements), certificate, report or other data
     furnished or to be furnished or made by Borrowers under any Loan
     Document, including this Agreement, proves to have been untrue in any
     material respect, as of the date as of which the facts therein set
     forth were stated or certified; or

          (c)       Default shall be made in the due observance or performance
     of any of the covenants or agreements of the Borrowers contained in

     period), and such default shall continue for more than thirty (30)
     days after notice thereof from Agent to Borrowers; or

     otherwise), or any obligations secured by any mortgage, pledge or
     other security interest, lien, charge or encumbrance with respect
     thereto, on any asset or property of Borrowers in respect of any
     agreement relating to any such obligations unless Borrowers are not
     liable for same (i.e., unless remedies or recourse for failure to pay
     such obligations is limited to foreclosure of the collateral security
     therefor), and if such default shall continue beyond the applicable
     grace period, if any; or 

          (f)       Borrowers shall commence a voluntary case or other
     proceedings seeking liquidation, reorganization or other relief with
     respect to itself or its debts 

                                     -51-


     under any bankruptcy, insolvency or other similar law now or hereafter 
     in effect or seeking an appointment of a trustee, receiver, liquidator, 
     custodian or other similar official of it or any substantial part of its 
     property, or shall consent to any such relief or to the appointment of or 
     taking possession by any such official in an involuntary case or other
     proceeding commenced against it, or shall make a general assignment
     for the benefit of creditors, or shall fail generally to pay its debts
     as they become due, or shall take any corporate action authorizing the
     foregoing; or

          (g)       An involuntary case or other proceeding, shall be commenced
     against Borrowers seeking liquidation, reorganization or other relief
     with respect to it or its debts under any bankruptcy, insolvency or
     similar law now or hereafter in effect or seeking the appointment of a
     trustee, receiver, liquidator, custodian or other similar official of
     it or any substantial part of its property, and such involuntary case
     or other proceeding shall remain undismissed and unstayed for a period
     of sixty (60) days; or an order for relief shall be entered against
     Borrowers under the federal bankruptcy laws as now or hereinafter in
     effect; or

          (h)       A final judgment or order for the payment of money in excess
     of $1,500,000 (or judgments or orders aggregating in excess of
     $1,500,000) shall be rendered against Borrowers and such judgments or
     orders shall continue unsatisfied and unstayed for a period of thirty
     (30) days; or 

          (i)       In the event the Total Outstandings shall at any time exceed
     the Borrowing Base established for the Revolving Notes, and the
     Borrowers shall fail to comply with the provisions of Section 9(b)
     hereof; or

          (j)       A Change of Management shall occur; or

          (k)       Any Security Instrument shall for any reason not, or cease

     Collateral purportedly covered thereby and such occurrence would have
     a Material Adverse Effect; or

          (l)       The good faith determination by the Agent that a Material
     Adverse Effect has occurred or will occur or that the value of the
     Collateral has, or will be, materially decreased.

          Upon occurrence of any Event of Default specified in Subsections
     14(f) and (g) hereof, the entire principal amount due under the Notes
     and all interest then accrued thereon, and any other liabilities of
     the Borrowers hereunder, shall become immediately due and payable all
     without notice and without presentment, demand, protest, notice of
     protest or dishonor or any other notice of default of any kind, all of
     which are hereby expressly waived by the Borrowers.  In any other
     Event of Default, the Agent, upon request of Majority Banks, shall by
     notice to the 

                                     -52-


     Borrowers declare the principal of, and all interest then accrued on, the 
     Notes and any other liabilities hereunder to be forthwith due and payable, 
     whereupon the same shall forthwith become due and payable without 
     presentment, demand, protest, notice of intent to accelerate, notice of 
     acceleration or other notice of any kind, all of which the Borrowers hereby
     expressly waive, anything contained herein or in the Note to the contrary 
     notwithstanding.  Nothing contained in this Section 14 shall be construed 
     to limit or amend in any way the Events of Default enumerated in the Note, 
     or any other document executed in connection with the transaction 
     contemplated herein.

          Upon the occurrence and during the continuance of any Event of
     Default, the Banks are hereby authorized at any time and from time to
     time, without notice to the Borrowers (any such notice being expressly
     waived by the Borrowers), to set-off and apply any and all deposits
     (general or special, time or demand, provisional or final) at any time
     held and other indebtedness at any time owing by any of the Banks to
     or for the credit or the account of the Borrowers against any and all
     of the indebtedness of the Borrowers under the Notes and the Loan
     Documents, including this Agreement, irrespective of whether or not
     the Banks shall have made any demand under the Loan Documents,
     including this Agreement or the Notes and although such indebtedness
     may be unmatured.  Any amount set-off by any of the Banks shall be
     applied against the indebtedness owed the Banks by the Borrowers
     pursuant to this Agreement and the Notes.  The Banks agree promptly to
     notify the Borrowers after any such setoff and application, provided
     that the failure to give such notice shall not affect the validity of
     such set-off and application.  The rights of the Bank under this
     Section are in addition to other rights and remedies (including,
     without limitation, other rights of set-off) which the Banks may have.

     15.  THE AGENT AND THE BANKS.

          (a)       APPOINTMENT AND AUTHORIZATION.  Each Bank hereby appoints
     Agent as its nominee and agent, in its name and on its behalf: (i) to
     act as nominee for and on behalf of such Bank in and under all Loan
     Documents; (ii) to arrange the means whereby the funds of Banks are to
     be made available to the Borrowers under the Loan Documents; (iii) to
     take such action as may be requested by any Bank under the Loan
     Documents (when such Bank is entitled to make such request under the
     Loan Documents); (iv) to receive all documents and items to be
     furnished to Banks under the Loan Documents; (v) to be the secured
     party, mortgagee, beneficiary, and similar party in respect of, and to
     receive, as the case may be, any collateral for the benefit of Banks;
     (vi) to promptly distribute to each Bank all material information,
     requests, documents and items received from the Borrowers under the
     Loan Documents; (vii) to promptly distribute to each Bank such Bank's
     Pro Rata Part of each payment or prepayment (whether voluntary, as
     proceeds of insurance thereon, or otherwise) in accordance with the
     terms of the Loan Documents and (viii) to 

                                     -53-


     deliver to the appropriate Persons requests, demands, approvals and 
     consents received from Banks.  Each Bank hereby authorizes Agent to take 
     all actions and to exercise such powers under the Loan Documents as are 
     specifically delegated to Agent by the terms hereof or thereof, together 
     with all other powers reasonably incidental thereto.  With respect to its 
     commitments hereunder and the Notes issued to it, Agent and any successor 
     Agent shall have the same rights under the Loan Documents as any other Bank
     and may exercise the same as though it were not the Agent; and the
     term "Bank" or "Banks" shall, unless otherwise expressly indicated,
     include Agent and any successor Agent in its capacity as a Bank. 
     Agent and any successor Agent and its Affiliates may accept deposits
     from, lend money to, act as trustee under indentures of and generally
     engage in any kind of business with the Borrowers, and any person
     which may do business with the Borrowers, all as if Agent and any
     successor Agent was not Agent hereunder and without any duty to
     account therefor to the Banks; provided that, if any payments in
     respect of any property (or the proceeds thereof) now or hereafter in
     the possession or control of Agent which may be or become security for
     the obligations of the Borrowers arising under the Loan Documents by
     reason of the general description of indebtedness secured or of
     property contained in any other agreements, documents or instruments
     related to any such other business shall be applied to reduction of
     the obligations of the Borrowers arising under the Loan Documents,
     then each Bank shall be entitled to share in such application
     according to its pro rata part thereof.  Each Bank, upon request of
     any other Bank, shall disclose to all other Banks all indebtedness and
     liabilities, direct and contingent, of the Borrowers to such Bank as
     of the time of such request.

          (b)       NOTE HOLDERS.  From time to time as other Banks become a
     party to this Agreement, Agent shall obtain execution by the Borrowers
     of additional Notes in amounts representing the Commitment of each
     such new Bank, up to an aggregate face amount of all Revolving Notes
     not exceeding $175,000,000.  The obligation of such Bank shall be
     governed by the provisions of this Agreement, including but not
     limited to, the obligations specified in Section 2 hereof.  From time
     to time, Agent may require that the Banks exchange their Notes for
     newly issued Notes to better reflect the Commitments of the Banks. 
     Agent may treat the payee of any Note as the holder thereof until
     written notice of transfer has been filed with it, signed by such
     payee and in form satisfactory to Agent.

          (c)       CONSULTATION WITH COUNSEL.  Banks agree that Agent may
     consult with legal counsel selected by Agent and shall not be liable
     for any action taken or suffered in good faith by it in accordance
     with the advice of such counsel.

          (d)       DOCUMENTS.  Agent shall not be under a duty to examine or
     pass upon the validity, effectiveness, enforceability, genuineness or
     value of any of the Loan Documents or any other instrument or document
     furnished pursuant thereto or 

                                     -54-


     in connection therewith, and Agent shall be entitled to assume that the 
     same are valid, effective, enforceable and genuine and what they purport 
     to be.

          (e)       RESIGNATION OR REMOVAL OF AGENT.  Subject to the appointment
     and acceptance of a successor Agent as provided below, Agent may
     resign at any time by giving written notice thereof to Banks and the
     Borrowers, and Agent may be removed at any time with or without cause
     by all Banks.  If no successor Agent has been so appointed by all
     Banks (and approved by the Borrowers) and has accepted such
     appointment within 30 days after the retiring Agent's giving of notice
     of resignation or removal of the retiring Agent, then the retiring
     Agent may, on behalf of Banks, appoint a successor Agent.  Any
     successor Agent must be approved by Borrowers, which approval will not
     be unreasonably withheld.  Upon the acceptance of any appointment as
     Agent hereunder by a successor Agent, such successor Agent shall
     thereupon succeed to and become vested with all the rights 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
     Section 15 shall continue in effect for its benefit in respect to any
     actions taken or omitted to be taken by it while it was acting as
     Agent.  To be eligible to be an Agent hereunder the party serving, or
     to serve, in such capacity must own a Pro Rata Part of the Commitments
     equal to the level of Commitment required to be held by any Bank
     pursuant to Section 28 hereof.

          (f)       RESPONSIBILITY OF AGENT.  It is expressly understood and
     agreed that the obligations of Agent under the Loan Documents are only
     those expressly set forth in the Loan Documents as to each and that
     Agent, shall be entitled to assume that no Default or Event of Default
     has occurred and is continuing, unless Agent has actual knowledge of
     such fact or has received notice from a Bank or the Borrowers that
     such Bank or the Borrowers considers that a Default or an Event of
     Default has occurred and is continuing and specifying the nature
     thereof.  Neither Agent nor any of its directors, officers, attorneys
     or employees shall be liable for any action taken or omitted to be
     taken by them under or in connection with the Loan Documents, except
     for its or their own gross negligence or willful misconduct.  Agent
     shall not incur liability under or in respect of any of the Loan
     Documents by acting upon any notice, consent, certificate, warranty or
     other paper or instrument believed by it to be genuine or authentic or
     to be signed by the proper party or parties, or with respect to
     anything which it may do or refrain from doing in the reasonable
     exercise of its judgment, or which may seem to it to be necessary or
     desirable.

          Agent shall not be responsible to Banks for any of the Borrowers'
     recitals, statements, representations or warranties contained in any
     of the Loan Documents, or in any certificate or other document
     referred to or provided for in, or received by any Bank under, the
     Loan Documents, or for the value, validity, effectiveness,
     genuineness, enforceability or sufficiency of or any of the Loan
     Documents or for 

                                     -55-


     any failure by the Borrowers to perform any of its obligations hereunder 
     or thereunder.  Agent may employ agents and attorneys-in-fact and shall 
     not be answerable, except as to money or securities received by it or its 
     authorized agents, for the negligence or misconduct of any such agents or 
     attorneys-in-fact selected by it with reasonable care.

          The relationship between Agent and each Bank is only that of
     agent and principal and has no fiduciary aspects.  Nothing in the Loan
     Documents or elsewhere shall be construed to impose on Agent any
     duties or responsibilities other than those for which express
     provision is therein made.  In performing its duties and functions
     hereunder, Agent does not assume and shall not be deemed to have
     assumed, and hereby expressly disclaims, any obligation or
     responsibility toward or any relationship of agency or trust with or
     for the Borrower or any of its beneficiaries or other creditors.  As
     to any matters not expressly provided for by the Loan Documents, Agent
     shall not be required to exercise any discretion or take any action,
     but shall be required to act or to refrain from acting (and shall be
     fully protected in so acting or refraining from acting) upon the
     instructions of all Banks and such instructions shall be binding upon
     all Banks and all holders of the Notes; provided, however, that Agent
     shall not be required to take any action which is contrary to the Loan
     Documents or applicable law.

          Agent shall have the right to exercise or refrain from
     exercising, without notice or liability to the Banks, any and all
     rights afforded to Agent by the Loan Documents or which Agent may have
     as a matter of law; provided, however, Agent shall not (i) except as
     provided in Section 7(b) hereof, without the consent of Majority Banks
     designate the amount of the Borrowing Base or the Monthly Commitment
     Reduction or (ii) without the consent of all Majority Banks, take any
     other action with regard to amending the Loan Documents, waiving any
     default under the Loan Documents or taking any other action with
     respect to the Loan Documents which requires consent of all Banks. 
     Provided further, however, that no amendment, waiver, or other action
     shall be effected pursuant to the preceding clause (ii) without the
     consent of all Banks which: (i) would increase the Borrowing Base or
     decrease the Monthly Commitment Reduction, (ii) would reduce any fees
     hereunder, or the principal of, or the interest on, any Bank's Note or
     Notes, (iii) would postpone any date fixed for any payment of any fees
     hereunder, or any principal or interest of any Bank's Note or Notes,
     (iv) would materially increase any Bank's obligations hereunder or
     would materially alter Agent's obligations to any Bank hereunder, (v)
     would release Borrowers from their obligation to pay any Bank's Note
     or Notes, (vi) release any of the Collateral, (vii) would change the
     definition of all Banks, (viii) would amend, modify or change any
     provision of this Agreement requiring the consent of all the Banks,
     (ix) would waive any of the conditions precedent to the Effective Date
     or the making of any Loan or issuance of any Letter of Credit or
     (x) would extend the Revolving Maturity Date or (xi) would 

                                     -56-


     amend this sentence or the previous sentence.  Agent shall not have 
     liability to Banks for failure or delay in exercising any right or power 
     possessed by Agent pursuant to the Loan Documents or otherwise unless such
     failure or delay is caused by the gross negligence of the Agent, in
     which case only the Agent responsible for such gross negligence shall
     have liability therefor to the Banks.

          (g)       INDEPENDENT INVESTIGATION.  Each Bank severally represents
     and warrants to Agent that it has made its own independent
     investigation and assessment of the financial condition and affairs of
     the Borrowers in connection with the making and continuation of its
     participation hereunder and has not relied exclusively on any
     information provided to such Bank by Agent in connection herewith, and
     each Bank represents, warrants and undertakes to Agent that it shall
     continue to make its own independent appraisal of the credit
     worthiness of the Borrowers while the Notes are outstanding or its
     commitments hereunder are in force.  Agent shall not be required to
     keep itself informed as to the performance or observance by the
     Borrowers of this Agreement or any other document referred to or
     provided for herein or to inspect the properties or books of the
     Borrowers.  Other than as provided in this Agreement, Agent shall not
     have any duty, responsibility or liability to provide any Bank with
     any credit or other information concerning the affairs, financial
     condition or business of the Borrowers which may come into the
     possession of Agent.

          (h)       INDEMNIFICATION. Banks agree to indemnify Agent, ratably
     according to their respective Commitments on a Pro Rata basis, from
     and against any and all liabilities, obligations, losses, damages,
     penalties, actions, judgments, suits, costs, expenses or disbursements
     of any proper and reasonable kind or nature whatsoever which may be
     imposed on, incurred by or asserted against Agent in any way relating
     to or arising out of the Loan Documents or any action taken or omitted
     by Agent under the Loan Documents, provided that no Bank shall be
     liable for any portion of such liabilities, obligations, losses,
     damages, penalties, actions, judgments, suits, costs, expenses or
     disbursements resulting from Agent's gross negligence or willful
     misconduct.  Each Bank shall be entitled to be reimbursed by the Agent
     for any amount such Bank paid to Agent under this Section 15(h) to the
     extent the Agent has been reimbursed for such payments by the
     Borrowers or any other Person.  THE PARTIES INTEND FOR THE PROVISIONS
     OF THIS SECTION TO APPLY TO AND PROTECT THE AGENT FROM THE
     CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR
     THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF
     ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE,
     CONTRIBUTING OR CONCURRING CAUSE OF ANY SUCH LIABILITY.

          (i)       BENEFIT OF SECTION 15.  The agreements contained in this
     Section 15 are solely for the benefit of Agent and the Banks and are
     not for the benefit of, or to be relied upon by, the Borrowers, any
     affiliate of the Borrowers or any other person.

                                     -57-


          (j)    PRO RATA TREATMENT.  Subject to the provisions of this
     Agreement, each payment (including each prepayment) by the Borrowers
     and collection by Banks (including offsets) on account of the
     principal of and interest on the Notes and fees provided for in this
     Agreement, payable by the Borrowers shall be made Pro Rata; provided,
     however, in the event that any Defaulting Bank shall have failed to
     make an Advance as contemplated under Section 3 hereof and Agent or
     another Bank or Banks shall have made such Advance, payment received
     by Agent for the account of such Defaulting Bank or Banks shall not be
     distributed to such Defaulting Bank or Banks until such Advance or
     Advances shall have been repaid in full to the Bank or Banks who
     funded such Advance or Advances.

          (k)    ASSUMPTION AS TO PAYMENTS.  Except as specifically provided
     herein, unless Agent shall have received notice from the Borrowers
     prior to the date on which any payment is due to Banks hereunder that
     the Borrowers will not make such payment in full, Agent may, but shall
     not be required to, assume that the Borrowers have made such payment
     in full to Agent on such date and Agent may, in reliance upon such
     assumption, cause to be distributed to each Bank on such due date an
     amount equal to the amount then due such Bank.  If and to the extent
     the Borrowers shall not have so made such payment in full to Agent,
     each Bank shall repay to Agent forthwith on demand such amount
     distributed to such Bank together with interest thereon, for each day
     from the date such amount is distributed to such Bank until the date
     such Bank repays such amount to Agent, at the interest rate applicable
     to such portion of the Revolving Loan.

          (l)    OTHER FINANCINGS.  Without limiting the rights to which any
     Bank otherwise is or may become entitled, such Bank shall have no
     interest, by virtue of this Agreement or the Loan Documents, in
     (a) any present or future loans from, letters of credit issued by, or
     leasing or other financial transactions by, any other Bank to, on
     behalf of, or with the Borrowers (collectively referred to herein as
     "Other Financings") other than the obligations hereunder; (b) any
     present or future guarantees by or for the account of the Borrowers
     which are not contemplated by the Loan Documents; (c) any present or
     future property taken as security for any such Other Financings; or
     (d) any property now or hereafter in the possession or control of any
     other Bank which may be or become security for the obligations of the
     Borrowers arising under any loan document by reason of the general
     description of indebtedness secured or property contained in any other
     agreements, documents or instruments relating to any such Other
     Financings.

          (m)    INTERESTS OF BANKS.  Nothing in this Agreement shall be
     construed to create a partnership or joint venture between Banks for
     any purpose.  Agent, Banks and the Borrowers recognize that the
     respective obligations of Banks under the Revolving Commitment shall
     be several and not joint and that neither Agent nor 


                                    -58-



     any of Banks shall be responsible or liable to perform any of the 
     obligations of the other under this Agreement.  Each Bank is deemed to 
     be the owner of an undivided interest in and to all rights, titles, 
     benefits and interests belonging and accruing to Agent under the 
     Security Instruments, including, without limitation, liens and security 
     interests in any collateral, fees and payments of principal and interest 
     by the Borrowers under the Revolving Commitment on a Pro Rata basis.  
     Each Bank shall perform all duties and obligations of Banks under this 
     Agreement in the same proportion as its ownership interest in the Loans 
     outstanding at the date of determination thereof.

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

     16.  EXERCISE OF RIGHTS.  No failure to exercise, and no delay in
exercising, on the part of the Agent or the Banks, any right hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right.  The rights of the Agent and the Banks hereunder shall be in addition to
all other rights provided by law.  No modification or waiver of any provision of
the Loan Documents, including this Agreement, or the Note nor consent to
departure therefrom, shall be effective unless in writing, and no such consent
or waiver shall extend beyond the particular case and purpose involved.  No
notice or demand given in any case shall constitute a waiver of the right to
take other action in the same, similar or other circumstances without such
notice or demand.

     17.  NOTICES.  Any notices or other communications required or
permitted to be given by this Agreement or any other documents and instruments
referred to herein must be given in writing (which may be by facsimile
transmission) and must be personally delivered or mailed by prepaid certified or
registered mail to the party to whom such notice or communication is directed at

change its address for purposes of this Agreement by giving notice of such 
change to the other party pursuant to this Section 17. Any notice required to 
be given to the Banks shall be given to the Agent and distributed to all 
Banks by the Agent.

     18.  EXPENSES.  The Borrowers shall pay (i) all reasonable and
necessary out-of-pocket expenses of the Banks, including reasonable fees and
disbursements of special counsel for the Agent, in connection with the
preparation of this Agreement, any waiver or consent hereunder or any amendment
hereof or any default or Event of Default or alleged default or Event of Default
hereunder, (ii) all reasonable and necessary out-of-pocket expenses of the
Agent, including reasonable fees and disbursements of special counsel for the
Agent in connection with the preparation of any participation agreement for a
participant or participants requested by the Borrowers or any amendment thereof
and (iii) if a default or an Event of Default occurs, all reasonable and
necessary out-of-pocket expenses incurred by the Banks, including reasonable
fees and disbursements of counsel, in connection with such default and Event of
Default and collection and other enforcement proceedings resulting therefrom. 
The Borrowers shall indemnify the Banks against any transfer taxes, document
taxes, assessments or charges made by any governmental authority by reason of
the execution, delivery and filing of the Loan Documents.  The obligations of
this Section 18 shall survive any termination of this Agreement, the expiration
of the Loans and the payment of all indebtedness of the Borrowers to the Banks
hereunder and under the Notes.

     19.  INDEMNITY.  The Borrowers agree to indemnify and hold harmless
the Banks and their respective officers, employees, agents, attorneys and
representatives (singularly, an "Indemnified Party", and collectively, the
"Indemnified Parties") from and against any loss, cost, liability, damage or
expense (including the reasonable fees and out-of-pocket expenses of counsel to
the Banks, including all local counsel hired by such counsel) ("Claim") incurred
by the Banks in investigating or preparing for, defending against, or providing
evidence, producing documents or taking any other action in respect of any
commenced or threatened litigation, administrative proceeding or investigation
under any federal securities law, federal or state environmental law, or any
other statute of any jurisdiction, or any regulation, or at common law or
otherwise, which is alleged to arise out of or is based upon any acts, practices
or omissions or alleged acts, practices or omissions of the Borrowers or their
agents or arises in connection with the duties, obligations or performance of
the Indemnified Parties in negotiating, preparing, executing, accepting,
keeping, completing, countersigning, issuing, selling, delivering, releasing,
assigning, handling, certifying, processing or receiving or taking any other
action with respect to the Loan Documents and all documents, items and materials
contemplated thereby even if any of the foregoing arises out of an Indemnified
Party's ordinary negligence.  The indemnity set forth herein shall be in
addition to any other obligations or liabilities of the Borrowers to the Banks
hereunder or at common law or otherwise, and shall survive any termination of
this Agreement, the expiration of the Loans and the payment of all indebtedness
of the Borrowers to the Banks hereunder and under the Notes, provided that the
Borrowers shall have no obligation under this Section to the Bank with respect
to 


                                    -60-



any of the foregoing arising out of the gross negligence or willful 
misconduct of the Bank.  If any Claim is asserted against any Indemnified 
Party, the Indemnified Party shall endeavor to notify the Borrowers of such 
Claim (but failure to do so shall not affect the indemnification herein made 
except to the extent of the actual harm caused by such failure).  The 
Indemnified Party shall have the right to employ, at the Borrowers' expense, 
counsel of the Indemnified Parties' choosing and to control the defense of 
the Claim.  The Borrowers may at their own expense also participate in the 
defense of any Claim.  Each Indemnified Party may employ separate counsel in 
connection with any Claim to the extent such Indemnified Party believes it 
reasonably prudent to protect such Indemnified Party.  THE PARTIES INTEND FOR 
THE PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT EACH INDEMNIFIED PARTY 
FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR 
THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF ITS OWN 
NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING, OR 
CONCURRING CAUSE OF ANY CLAIM.

     20.  GOVERNING LAW.  THIS AGREEMENT IS BEING EXECUTED AND DELIVERED,
AND IS INTENDED TO BE PERFORMED, IN OKLAHOMA, OKLAHOMA COUNTY, OKLAHOMA, AND THE
SUBSTANTIVE LAWS OF OKLAHOMA SHALL GOVERN THE VALIDITY, CONSTRUCTION,
ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT AND ALL OTHER DOCUMENTS AND
INSTRUMENTS REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN.

     21.  INVALID PROVISIONS.  If any provision of this Agreement is held
to be illegal, invalid, or unenforceable under present or future laws effective
during the term of this Agreement, such provisions shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part of this Agreement, and the
remaining provisions of the Agreement shall remain in full force and effect and
shall not be affected by the illegal, invalid or unenforceable provision or by
its severance from this Agreement.

     22.  MAXIMUM INTEREST RATE.  It is the intention of the parties hereto
to comply strictly with any applicable usury laws as in effect from time to time
and, in this regard, there shall never be taken, received, contracted for,
collected, charged or received on any sums advanced hereunder interest in excess
of that which would accrue at the Maximum Rate.

     If, under any circumstances, the aggregate amounts paid on the Notes
or under this Agreement or any other Loan Document include amounts which by law
are deemed interest and which would exceed the amount permitted if the Maximum
Rate were in effect, the Borrowers stipulate that such payment and collection
will have been and will be deemed to have been, to the fullest extent permitted
by applicable laws of the State of Oklahoma or the United States of America, the
result of mathematical error on the part of the Borrowers and the Agent; and the
Agent shall promptly credit the amount of such excess to the principal amount
due on the Notes, or if the principal amount due on the Notes shall have been
paid in full, refund the amount of such excess to the Borrowers (to the extent
only of such interest payments in excess of that which would have accrued and
been payable on the basis of the Maximum Rate) upon discovery of such error by


                                    -61-



the Agent or notice thereof from the Borrowers.

     If the maturity of the Notes is accelerated by reason of an election
of the Agent resulting from any Event of Default or otherwise in accordance with
this Agreement, or in the event any prepayment, then such consideration that
constitutes interest under applicable laws may never include amounts which are
more than the Maximum Rate, and the amount of such excess, if any, provided for
in this Agreement or otherwise shall be canceled automatically by the Agent as
of the date of such acceleration or prepayment and, if theretofore paid, shall
be credited by the Agent on the principal amount due on the Notes, or if the
principal amount due on the Notes shall have been paid in full, refunded by the
Agent to the Borrowers.

     All sums paid, or agreed to be paid, to the Agent for the use,
forbearance and detention of the proceeds of any Advance hereunder shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term hereof until paid in full so that the actual rate of
interest is uniform but does not exceed the Maximum Rate throughout the full
term hereof.

     23.  AMENDMENTS.  This Agreement may be amended only by an instrument
in writing executed by an authorized officer of the party against whom such
amendment is sought to be enforced.

     24.  MULTIPLE COUNTERPARTS.  This Agreement may be executed in a
number of identical separate counterparts, each of which for all purposes is to
be deemed an original, but all of which shall constitute, collectively, one
agreement.  No party to this Agreement shall be bound hereby until a counterpart
of this Agreement has been executed by all parties hereto.

     25.  CONFLICT.  In the event any term or provision hereof is
inconsistent with or conflicts with any provision of the Loan Documents, the
terms or provisions contained in this Agreement shall be controlling.

     26.  SURVIVAL.  All covenants, agreements, undertakings,
representations and warranties made in the Loan Documents, including this
Agreement, the Notes or other documents and instruments referred to herein shall
survive all closings hereunder and shall not be affected by any investigation
made by any party.

     27.  PARTIES BOUND.  This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors, assigns,
heirs, legal representatives and estates, provided, however, that the Borrowers
may not, without the prior written consent of all of the Banks, assign any
rights, powers, duties or obligations hereunder.

     28.  ASSIGNMENTS AND PARTICIPATIONS.

          (a)    Each Bank shall have the right to sell, assign or transfer
     all or any 


                                    -62-



     part of its Note or Notes, its Commitments and its rights and 
     obligations hereunder to one or more Affiliates, Banks, financial 
     institutions, pension plans, insurance companies, investment funds, or 
     similar Persons who are Eligible Assignees or to a Federal Reserve Bank; 
     PROVIDED, that in connection with each sale, assignment or transfer 
     (other than to an Affiliate, a Bank or a Federal Reserve Bank), the 
     applicable Bank will consider the opinion and recommendation of 
     Borrowers, which opinion and recommendation shall in no way be binding 
     upon such Bank, and each such sale, assignment, or transfer (other than 
     to an Affiliate, a Bank or a Federal Reserve Bank), shall require the 
     consent of Agent, which consent will not be unreasonably withheld, and 
     the assignee, transferee or recipient shall have, to the extent of such 
     sale, assignment, or transfer, the same rights, benefits and obligations 
     as it would if it were such Bank and a holder of such Note, Commitments 
     and rights and obligations, including, without limitation, the right to 
     vote on decisions requiring consent or approval of all Banks or Majority 
     Banks and the obligation to fund its Commitments; provided, further, 
     that (1) each such sale, assignment, or transfer (other than to an 
     Affiliate, a Bank or a Federal Reserve Bank) shall be in an aggregate 
     principal amount not less than $5,000,000, (2) each remaining Bank shall 
     at all times maintain Commitments then outstanding in an aggregate 
     principal amount at least equal to $5,000,000; (3) each such sale, 
     assignment or transfer shall be of a Pro Rata portion of such Bank's 
     Revolving Commitment and its Bridge Loan Commitment, (4) no Bank may 
     offer to sell its Note or Notes, Commitments, rights and obligations or 
     interests therein in violation of any securities laws; and (5) no such 
     assignments (other than to a Federal Reserve Bank) shall become 
     effective until the assigning Bank and its assignee delivers to Agent 
     and Borrowers an Assignment and Acceptance and the Note or Notes subject 
     to such assignment and other documents evidencing any such assignment.  
     An assignment fee in the amount of $5,000 for each such assignment 
     (other than to an Affiliate, a Bank or the Federal Reserve Bank) will be 
     payable to Agent by assignor or assignee.  Within five (5) Business Days 
     after its receipt of copies of the Assignment and Acceptance and the 
     other documents relating thereto and the Note or Notes, the Borrowers 
     shall execute and deliver to Agent (for delivery to the relevant 
     assignee) a new Note or Notes evidencing such assignee's assigned 
     Commitments and if the assignor Bank has retained a portion of its 
     Commitments, a replacement Note in the principal amount of the 
     Commitments retained by the assignor (except as provided in the last 
     sentence of this paragraph (a) such Note or Notes to be in exchange for, 
     but not in payment of, the Note or Notes held by such Bank).  On and 
     after the effective date of an assignment hereunder, the assignee shall 
     for all purposes be a Bank, party to this Agreement and any other Loan 
     Document executed by the Banks and shall have all the rights and 
     obligations of a Bank under the Loan Documents, to the same extent as if 
     it were an original party thereto, and no further consent or action by 
     Borrowers, Banks or the Agent shall be required to release the 
     transferor Bank with respect to its Commitments assigned to such 
     assignee and the transferor Bank shall henceforth be so released.


                                    -63-



          (b)    Each Bank shall have the right to grant participations in
     all or any part of such Bank's Notes and Commitments hereunder to one
     or more pension plans, investment funds, insurance companies,
     financial institutions or other Persons, provided, that:

                 (i)    each Bank granting a participation shall retain the
          right to vote hereunder, and no participant shall be entitled to
          vote hereunder on decisions requiring consent or approval of Bank
          or Majority Banks (except as set forth in (iii) below);

                 (ii)   in the event any Bank grants a participation hereunder,
          such Bank's obligations under the Loan Documents shall remain
          unchanged, such Bank shall remain solely responsible to the other
          parties hereto for the performance of such obligations, such Bank
          shall remain the holder of any such Note or Notes for all
          purposes under the Loan Documents, and Agent, each Bank and
          Borrowers shall be entitled to deal with the Bank granting a
          participation in the same manner as if no participation had been
          granted; and 

                 (iii)  no participant shall ever have any right by reason
          of its participation to exercise any of the rights of Banks
          hereunder, except that any Bank may agree with any participant
          that such Bank will not, without the consent of such participant
          (which consent may not be unreasonably withheld) consent to any
          amendment or waiver requiring approval of all Banks.

          (c)    It is understood and agreed that any Bank may provide to
     assignees and participants and prospective assignees and participants
     financial information and reports and data concerning Borrowers'
     properties and operations which was provided to such Bank pursuant to
     this Agreement.

          (d)    Upon the reasonable request of either Agent or Borrowers,
     each Bank will identify those to whom it has assigned or participated
     any part of its Notes and Commitment, and provide the amounts so
     assigned or participated.
