The borrowings made by the Borrowers pursuant to the Revolving Commitment shall be made at the principal office of the Bank and shall be evidenced by the Revolving Note. The entire outstanding principal amount, and accrued and unpaid interest, under the Revolving Note is due on the Revolving Loan Termination Date or sooner pursuant to the terms of this Article II.

2.02 Advances and Payments of Principal Under the Revolving Note. Each time an advance is made against or payment is made on the Revolving Note, the Bank is hereby irrevocably authorized by the Borrowers to make appropriate entries of such in its records in accordance with the usual and customary practices of accounting for advances and payments on notes; provided, however, the failure of the Bank to do so shall not relieve the Borrowers of their correct liability hereunder or under the Revolving Note.

The aggregate unpaid amount of advances reflected by the notations by the Bank on its records or the ledger sheets affixed to the Revolving Note shall be deemed rebuttably presumptive evidence of the principal amount owing on the Revolving Note. The liability for payment of principal and interest evidenced by the Revolving Note shall be limited to principal amounts actually advanced to the Borrowers and outstanding under this Agreement and interest on such amounts calculated in accordance with this Agreement. Interest provided for in the Revolving Note and herein shall be calculated on unpaid sums actually advanced and outstanding under the Revolving Note pursuant to the terms of this Agreement and only for the period from the date or dates of such advances until repayment.

2.03 Payments of Interest under the Revolving Note. Subject to the terms and provisions of this Agreement, interest on the Revolving Loan, calculated at the Floating Rate, shall be due and payable quarterly as it accrues beginning August 31, 2003, and continuing thereafter on the last day of each succeeding calendar quarter while any amount remains owing on the Revolving Note and at the Revolving Loan Termination Date, the interest payment in each

instance to be that which has been earned and remains unpaid. The rate of interest charged on the Revolving Loan shall be adjusted, effective on the effective date of each change in the Base Rate, and in the ordinary course of business the Bank shall send written notice to the Parent Borrower that a change in the Base Rate has occurred.

2.04 General Provisions Relating to Interest. All Loans hereunder and outstanding from time to time shall bear interest at the Floating Rate, calculated on the basis of a year of three hundred sixty (360) days from the date of advance to, but not including, the date of repayment.

It is the intention of the parties hereto to comply strictly with the usury Laws of the State of Texas and the United States of America and, in this connection, there shall never be collected, charged or received on any sums advanced hereunder interest in excess of the Maximum Rate. For purposes of Chapter 303 of the Texas Finance Code, as amended, the Borrowers agree that the maximum rate to be charged shall be the “indicated (weekly) rate ceiling” as defined in said Chapter, provided that the Bank may also rely to the extent permitted by applicable Laws of the State of Texas or the United States of America, on alternative maximum rates of interest under other applicable Laws of the State of Texas or the United States of America applicable to the Bank, if greater. Notwithstanding anything herein or in the Note to the contrary, during any Limitation Period, the interest rate to be charged on amounts evidenced by the Note shall be the Maximum Rate and the obligation of any Borrower for any fees payable hereunder and deemed to be interest under applicable Law shall be suspended. During any period or periods of time following a Limitation Period, to the extent permitted by applicable Laws of the State of Texas or the United States of America, the interest rate to be charged hereunder shall remain at the Maximum Rate until such time as there has been paid to the Bank (a) the amount of interest in excess of the Maximum Rate that the Bank would have received during the Limitation Period had the interest rate remained at the relevant rates specified in the Note, and (b) all interest and fees otherwise due to the Bank but for the effect of such Limitation Period.

If under any circumstances the aggregate amounts paid on the Note or under this Agreement include amounts which by Law are deemed interest and which would exceed the amount permitted if the Maximum Rate were in effect, each Borrower stipulates that such payment and collection will have been and will be deemed to have been, to the extent permitted by applicable Laws of the State of Texas or the United States of America, the result of mathematical error on the part of both the Borrowers and the Bank, and the Bank shall promptly refund the amount of such excess (to the extent only of such interest payments above the Maximum Rate which could lawfully have been collected and retained) upon discovery of such error by the Bank or notice thereof from the Borrowers.

Within twenty (20) Business Days after receipt of each such report, the Bank shall endeavor to, in the normal course of business, make a determination of the portion of the Borrowing Base attributable to the Borrowing Base Oil and Gas Properties and the Monthly Borrowing Base Reduction which shall become effective upon written notification from the Bank to the Parent Borrower, and which, subject to the other provisions of this Agreement, shall be the portion of the Borrowing Base attributable to the Borrowing Base Oil and Gas Properties and the Monthly Borrowing Base Reduction until the effective date of the next redetermination of the portion of the Borrowing Base attributable to the Borrowing Base Oil and Gas Properties and the Monthly Borrowing Base Reduction as set forth in this Section 2.05(c).

The Borrowers may, by written notice, request that the Bank redetermine the portion of the Borrowing Base attributable to the Borrowing Base Oil and Gas Properties and also redetermine the Monthly Borrowing Base Reduction, but not more often than once between two consecutive scheduled deliveries of such reports (“Optional Review”). Any request for an Optional Review must be in writing and shall be accompanied by a complete report relating to the Proved Reserves attributable to Borrowing Base Oil and Gas Properties and shall be prepared by an independent petroleum engineer or firm of engineers satisfactory to the Bank. Within twenty (20) Business Days after receipt of such report, the Bank shall endeavor to, in the normal course of business make a determination of the portion of the Borrowing Base attributable to the Borrowing Base Oil and Gas Properties and the Monthly Borrowing Base Reduction which shall become

effective upon written notification from the Bank to the Parent Borrower, and which, subject to the other provisions of this Agreement, shall be the portion of the Borrowing Base attributable to the Borrowing Base Oil and Gas Properties and the Monthly Borrowing Base Reduction until the effective date of the next redetermination of the portion of the Borrowing Base and the Monthly Borrowing Base Reduction as set forth in this Section 2.5(c). If the Borrowers’ request relates to a proposal to add Oil and Gas Properties of the Borrowers to the Borrowing Base Oil and Gas Properties, such proposal shall also be accompanied by evidence sufficient to establish that the respective Borrower or Borrowers own Marketable Title to such Oil and Gas Properties, and any such addition shall become effective at such time as: (a) the Bank has made its determination, in its sole discretion, of the amount by which the Borrowing Base would be increased as the result of such addition and (b) the conditions set forth in Article III hereof, to the extent they are applicable to such additional Oil and Gas Properties of such Borrower, have been satisfied.

The Bank may redetermine the Borrowing Base and the Monthly Borrowing Base Reduction, at any time, and from time to time, but not more often than once between two scheduled deliveries of such reports as described above, which redetermination shall become effective upon written notification from the Bank to the Parent Borrower and which, subject to the other provisions of this Agreement, shall be the Borrowing Base and the Monthly Borrowing Base Reduction until the effective date of the next redetermination of the Borrowing Base and the Monthly Borrowing Base Reduction, as set forth in this Section. The Bank may require the Borrowers to provide a report prepared by an independent petroleum engineer or firm of engineers reasonably satisfactory to the Bank regarding the Proved Reserves attributable to the Borrowing Base Oil and Gas Properties at any time upon ninety (90) days advance notice to the Borrowers.

(d) The Borrowing Base shall represent the Bank’s determination, in accordance with its customary lending practices, of the maximum loan amount with respect to the Borrowing Base Receivables and the Borrowing Base Oil and Gas Properties and the Borrowers acknowledge, for purposes of this Agreement, such determination by the Bank as being the maximum loan amount with respect to the Borrowing Base Receivables and the Borrowing Base Oil and Gas Properties. In making any redetermination of the Borrowing Base, the Bank shall apply the parameters then generally being utilized by the Bank for Borrowing Base redeterminations for other similarly situated borrowers. The Borrowers and the Bank acknowledge that (a) due to the uncertainties of the oil and gas extraction process, the Borrowing Base Oil and Gas Properties are not subject to evaluation with a high degree of accuracy and are subject to potential rapid deterioration in value, and (b) for this reason and the difficulties and expenses involved in liquidating and collecting against the Borrowing Base Oil and Gas Properties, the Bank’s determination of the maximum loan amount with respect to the Borrowing Base Oil and Gas Properties contains an equity cushion, which equity cushion is acknowledged by the Borrowers as essential for the adequate protection of the Bank.

NOTWITHSTANDING ANYTHING TO THE CONTRARY UNDER THIS AGREEMENT OR ANY LOAN DOCUMENT, AS OF THE DATE OF CLOSING, THE BORROWERS AND THE BANK ACKNOWLEDGE AND AGREE THAT IN APPLICATION

BY THE BANK OF THE ABOVE-NOTED PARAMETERS AND STANDARDS, NO BORROWING BASE IS ATTRIBUTED TO THE BORROWING BASE OIL AND GAS PROPERTIES DESCRIBED ON EXHIBIT “A” ATTACHED HERETO. ANY FUTURE ALLOCATION OF BORROWING BASE ATTRIBUTABLE TO THE BORROWING BASE OIL AND GAS PROPERTIES SHALL BE IN CONFORMANCE WITH THIS SECTION 2.05.

(a) In the event that the Bank determines that a Loan Excess exists, the Borrowers shall immediately, but in no event later than fifteen (15) days following notice from the Bank of any such scheduled or non-scheduled Borrowing Base determination, shall provide written notice to Bank regarding which of the following options it plans to implement and within thirty (30) days of such notice from Bank, Borrowers shall either (i) prepay the principal of the Revolving Note in an aggregate amount at least equal to such Loan Excess, (ii) add to the Borrowing Base Oil and Gas Properties additional Oil and Gas Properties of the Borrowers sufficient in value, as determined by the Bank in its sole discretion pursuant to Section 2.05, to increase the Borrowing Base in the amount of such Loan Excess, (iii) add other assets of the Borrowers to the Borrowing Base that are of the type and that have sufficient value, as determined by the Bank in its sole discretion, to increase the Borrowing Base in the amount of such Loan Excess or (iv) make a first of three (3) installments in order to repay the Loan Excess, each of three (3) installments to be in the amount of at least one third (1/3) of the original amount of the Loan Excess (or the remaining unpaid balance of such Loan Excess, if less than one third thereof remains), and pay each of the next two installments on or before the expiration of thirty (30) days and sixty (60) days, respectively, after the date of such first payment due date. Notwithstanding the foregoing provisions of this Section, the Borrowers shall pay the amount of any Loan Excess that would result from the application of each Periodic Borrowing Base Reduction and each Monthly Borrowing Base Reduction on or before the day that such Monthly Borrowing Base Reduction and/or Periodic Borrowing Base Reduction becomes applicable.

(b) In addition to the foregoing, the Borrowers shall immediately prepay the principal of the Revolving Note equal to:

(i) 100% of Net Proceeds from the disposition of any asset, excluding hydrocarbon lease sales, permitted under this Agreement including, without limitation, Net Proceeds attributable to any disposition of Cheniere-Gryphon’s equity interest in Gryphon Exploration;

(ii) 100% of insurance proceeds in excess of $100,000 per occurrence in respect of any insurance policy required to be maintained by the Borrowers under the terms of this Agreement unless Borrowers reinvest such proceeds within thirty (30) days of any insurable loss to replace the lost or damaged assets;

(iii) 50% of the Net Proceeds from the sale or issuance (after the date of this Agreement) of any capital stock, excluding capital stock issued

upon the exercise of existing warrants or options, of the Parent Borrower or any Subsidiary of Parent Borrower; and

(iv) 100% of any Indebtedness incurred by any Borrower, other than Permitted Indebtedness.

Bank shall provide Parent Borrower notice regarding any redetermination of the Monthly Borrowing Base Reduction and/or the Borrowing Base, and any such redetermination shall be effective upon written notification by Bank to Parent Borrower.

2.07 Advances to Satisfy Obligations of the Borrowers. The Bank may, but shall not be obligated to, make advances hereunder and apply same to the satisfaction of any condition, warranty, representation or covenant of the Borrowers contained in this Agreement, and the funds so advanced and applied shall be part of the Loan proceeds advanced under this Agreement and evidenced by the Revolving Note.

2.08 Assignment of Production. Certain of the Security Instruments covering the Borrowing Base Oil and Gas Properties, if and when executed pursuant to this Agreement, will contain an assignment unto and in favor of the Bank of all oil, gas and other minerals produced and to be produced from or attributable to the Borrowing Base Oil and Gas Properties together with all of the revenues and proceeds attributable to such production, and such Security Instruments will further provide that all such revenues and proceeds which may be so collected by the Bank pursuant to the assignment shall be applied to the payment of the Note and the satisfaction of all other Indebtedness to be secured by such Security Instruments. The Borrowers hereby appoint the Bank as their agent and attorney-in-fact until this Agreement has been terminated in accordance with Section 8.20 hereof for purposes of completing the Transfer Order Letters if and when delivered to the Bank pursuant to Section 3.01 hereof or otherwise under this Agreement, which power is coupled with an interest and is not revocable.

2.09 Commitment Fee. As consideration for the commitment of the Bank to make Loans to the Borrowers through the Revolving Loan Termination Date pursuant to this Agreement, the Borrowers agree to pay to the Bank within five (5) Business Days of receipt of the Bank’s statement to Parent Borrower as to quarterly periods ending March 31, June 30, September 30 and December 31 of each year (except the first period shall be for a period of time from the Closing to July 30, 2003) during the period commencing on the date of this Agreement to and including the Revolving Loan Termination Date and at the Revolving Loan Termination Date, a fee equal to 0.5% per annum (computed on the basis of 360) multiplied by an amount equal to the daily average excess, if any, of the Revolving Commitment over the aggregate principal amount outstanding on the Note, throughout the period from the date of this Agreement or previous calculation date provided above, whichever is later, to the relevant calculation date or the Revolving Loan Termination Date, as the case may be.

2.10 Facility Fee. As consideration for the commitment of the Bank to make Loans to the Borrowers pursuant to this Agreement, the Borrowers shall pay to the Bank a facility fee of $20,000 simultaneously with the Closing. Any time the Borrowing Base is increased pursuant to Section 2.05, an additional facility fee shall be paid to Bank by Borrowers

in the amount of 1.0% of any such increase above the highest Borrowing Base that was in effect at any time prior to such increase.

2.11 Professional Fees and Expenses. In addition to the other fees payable and expenses reimbursable by the Borrowers hereunder, the Borrowers agree to pay any and all professional fees and expenses incurred by the Bank, including, without limitation, engineering fees and expenses, incurred by Bank in the evaluation of such Borrowing Base Oil and Gas Properties.

2.12 Adjustment to Revolving Commitment Limit. At any time that Borrowers propose to increase the Borrowing Base by adding additional Oil and Gas Properties to the Borrowing Base Oil and Gas Properties pursuant to Section 2.05, Borrowers may also request that Bank increase the amount of the Revolving Commitment Limit. At any time that Borrowers make such a request, they shall promptly provide Bank with such financial information as Bank may request to assist the Bank in evaluating such request. Following the receipt of such information from Borrowers, the Bank shall, in the normal course of its business, make a redetermination of the Revolving Commitment Limit, which shall become effective upon written notification from the Bank to Parent Borrower of the new Revolving Commitment Limit. The Borrowers may, on a quarterly basis, upon written notice to the Bank, amend the definition of the Revolving Commitment Limit by reducing the amount set forth in such definition. Upon such reduction, the Bank shall not be obligated to extend Loans in excess of such reduced Revolving Commitment Limit. If and when the Bank increases the Revolving Commitment Limit at Borrowers’ request, the commitment fee, as determined pursuant to Section 2.09 of this Agreement, shall be calculated using such increased amount for all of the calculation periods in which such Revolving Commitment Limit was increased.

(a) Subject to the terms and conditions of this Agreement, the Bank agrees to issue standby letters of credit (“Letter(s) of Credit”) for the account of the Borrowers from time to time following receipt, at least three (3) Business Days prior to the requested date of issuance, of Bank’s then-current form of application for a Letter of Credit (“Letter of Credit Application”) properly completed by the Parent Borrower in such amount as the Borrowers may request not to exceed an aggregate amount outstanding equal to the unborrowed portion of the Revolving Commitment. The amount available to be drawn as Loans under the Revolving Commitment shall be reduced by the aggregate face amount of the outstanding Letters of Credit issued pursuant to this Section 2.13(a).

(b) If there is any conflict between the terms of any Letter of Credit Application accepted by the Bank and the terms of this Agreement, the terms of this Agreement shall control. No Letter of Credit shall have an expiration date that is later than six months from the date of its issuance, or, if sooner, beyond the Revolving Loan Termination Date.

2.14 Repayment of Letters of Credit. If drawn upon by the beneficiary of a Letter of Credit, all amounts so drawn shall be due and payable by the Borrowers immediately upon receipt of Bank’s request therefor.

2.15 Letter of Credit Fee. As consideration for the issuance by the Bank of Letters of Credit for the account of the Borrowers, the Borrowers agree to pay to the Bank a fee equal to the Applicable Margin times the amount of each such Letter of Credit (subject to a $500 minimum fee on each Letter of Credit), the first such per annum fee for each Letter of Credit to be payable in advance of the issuance of such Letter of Credit, with successive fees to be paid in advance of the expiration date of the issuance of such Letter of Credit if it is to remain in effect beyond such expiration date.

The obligation of the Bank to make the Loans is subject to the following conditions precedent:

Without limiting the generality of the foregoing, the Bank may immediately, without demand of performance and without other notice or demand whatsoever to the Borrowers, all of which are hereby expressly waived, and without advertisement, sell at public or private sale or otherwise realize upon, in Harris County, Texas, or in any other place where the Collateral may be located, or in such other place or places as the Bank may designate, the whole or, from time to

time, any part of the Collateral, or any interest which the Borrowers may have therein. After deducting from the proceeds of sale or other disposition of the Collateral all expenses (including all reasonable expenses for legal services), the Bank shall apply such proceeds toward the satisfaction of the Obligations. Any remainder of the proceeds after satisfaction in full of the Obligations shall be distributed as required by applicable Laws. Notice of any sale or other disposition shall be given to the Parent Borrower at least five (5) days before the time of any public sale or of the time after which any intended private sale or other disposition of the Collateral is to be made, which each Borrower hereby agrees shall be reasonable notice of such sale or other disposition. Each Borrower agrees to assemble, or to cause to be assembled, at its own expense, documents evidencing its ownership of the Collateral and such other documents or items as the Bank may reasonably request at such place or places as the Bank shall designate. At any such sale or other disposition, the Bank may, to the extent permissible under applicable Laws, purchase the whole or any part of the Collateral, free from any right of redemption on the part of any Borrower, which right is hereby waived and released. Without limiting the generality of any of the rights and remedies conferred upon the Bank under this paragraph, the Bank may, to the full extent permitted by the applicable Laws:

(A) Enter upon the premises of any Borrower (and, to the extent necessary in the judgment of the Bank, exclude therefrom any Borrower or any Affiliate thereof) and take immediate possession of the Collateral, either personally or by means of a receiver appointed by a court of competent jurisdiction, using all necessary force to do so;

(B) At the Bank’s option, use, operate, manage, and control the Collateral in any lawful manner;

(D) Maintain, repair, renovate, alter, or remove the Collateral as the Bank may determine in their discretion.

Upon the occurrence of any Event of Default, the Bank may, and is hereby authorized by each Borrower, at any time and from time to time, to the fullest extent permitted by applicable Laws, without advance notice to any Borrower (any such notice being expressly waived by each Borrower), set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and any other indebtedness at any time owing by the Bank to or for the credit or the account of each Borrower against any or all of the Obligations of each Borrower now or hereafter existing, whether or not such Obligations have matured and irrespective of whether the Bank may have exercised any other rights that they have or may have with respect to such Obligations, including, without limitation, any acceleration rights. The Bank agrees promptly to notify the Parent Borrower after any such set-off 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 7.05 are in addition to the other rights and remedies (including, without limitation, other rights of set-off) which the Bank may have.

8.01 Security Interests in Deposits and Right of Offset or the Banker’s Lien. Each Borrower hereby transfers, assigns and pledges to the Bank and/or grants to the Bank a security interest (as security for the payment and/or performance of the Obligations of the Borrowers, with such interest of the Bank to be retransferred, reassigned and/or released by the Bank at the expense of the Borrowers upon payment in full and/or complete performance by the Borrowers of all such Obligations) and the right, exercisable at such time as any obligation hereunder shall mature, whether by acceleration of maturity or otherwise, of offset or banker’s lien against all funds or other property of any Borrower now or hereafter or from time to time on deposit with or in the possession of the Bank, including, without limitation, all certificates of deposit and other depository accounts.

8.02 Survival of Representations, Warranties and Covenants. All representations and warranties of the Borrowers and all covenants and agreements herein made shall survive the execution and delivery of the Note and this Agreement and shall remain in force and effect so long as any debt is outstanding under the Note, or any renewal or extension of this Agreement or the Note, or the Bank remains obligated to make advances hereunder.

8.03 Notices and Other Communications. Notices, requests and communications hereunder shall be in writing and shall be sufficient in all respects if delivered to the relevant address indicated below (including delivery by registered or certified United States mail, facsimile, telex, telegram or hand):

Notwithstanding anything to the contrary under this Agreement, any provision relating to any notices, requests and communications to be made by Bank to any Borrower shall only be required to be made to Parent Borrower, and Bank shall only be required to rely on notices, requests and communications from Parent Borrower on behalf of itself and the other Borrowers and not from any other Borrower. Any party may, by proper written notice hereunder to the other, change the individuals or addresses to which such notices to it shall thereafter be sent.

No advance of Loan proceeds hereunder shall constitute a waiver of any of the covenants or warranties of any Borrower contained herein or of any of the conditions to the Bank’s obligation to make further advances hereunder. In the event that any Borrower is unable to satisfy any such covenant, warranty or condition, no such advance of Loan proceeds shall have the effect of precluding the Bank from thereafter declaring such inability to be an Event of Default as hereinabove provided.

(A) Waives (1) protest of all commercial paper at any time held by the Bank on which any Borrower is in any way liable; (2) except as the same may herein be specifically granted, notice of acceleration and intention to accelerate; and (3) notice and opportunity to be heard, after acceleration in the manner provided in Section 7.03, before exercise by the Bank of the remedies of self-help, set-off, or of other summary procedures permitted by any applicable Laws or by any agreement with any Borrower, and, except where required hereby or by any applicable Laws, notice of any other action taken by the Bank;

(B) Releases the Bank and its officers, employees, directors, attorneys, and agents (collectively, the “Bank Parties”) from all claims for loss or damage caused by any act or omission on the part of any of them except willful misconduct or gross negligence; and

(C) Agrees to indemnify and hold the Bank Parties harmless from and against all claims, damages, liabilities and expenses, known or unknown, accrued and unaccrued, unless attributable to the Bank Parties’ own gross negligence or willful misconduct, that may now or hereafter be asserted against any of the Bank Parties in connection with or arising out of any investigation, litigation or proceeding

directly or indirectly relating to or arising out of any of the transactions contemplated by this Agreement.
