(i)                                     Notwithstanding anything to the contrary herein, at any time after the repayment of all of the Debt evidenced by the Cubic Notes, by refinancing or otherwise, the Lender, at its sole discretion, may upon two hundred seventy (270) days notice to the Borrower make demand for payment for all or any portion of the Debt evidenced by any of the Notes.

(j)                                    Certain of the Security Documents contain an assignment unto and in favor of the Lender of all oil, gas and other minerals produced and to be produced from or attributable to the Mortgaged Properties together with all of the revenues and proceeds attributable to such production, and such Security Documents further provide that all such

20

revenues and proceeds which may be so collected by the Lender pursuant to such assignment shall be applied to the payment of the Notes and the satisfaction of all other Debt to be secured by such Security Documents.  The Lender and the Borrower expressly acknowledge and agree that so long as no Event of Default shall have occurred and be continuing, the Lender shall not enforce such assignment.  After the occurrence of an Event of Default hereunder, the Lender may enforce such assignment and apply such revenues and proceeds of the Borrower to the payment of the Notes and the satisfaction of all other Debt to be secured by such Security Documents, such application to be made in such manner as the Lender may elect, regardless of whether the application so made shall exceed the payment of principal and interest then due as provided above.  In connection with the rights of the Lender to all proceeds of production, upon the occurrence and continuation of an Event of Default, the Borrower hereby grants the Lender a power of attorney, which power is coupled with an interest and is irrevocable, to complete in all respects and deliver to the addressee the letter transfer orders executed in connection with the Security Documents.

(k)                                 Notwithstanding the terms of such Security Documents encumbering the Borrower’s Oil and Gas Properties, it is the intention of the Borrower and the Lender that in the absence of the enforcement of such assignment the Borrower will instruct all first purchasers of production, operators or other disbursers of proceeds of production to direct all proceeds of production from its Oil and Gas Properties to the Blocked Accounts.  The Lender and the Borrower also expressly acknowledge and agree, that notwithstanding the Security Documents, so long as no Event of Default shall have occurred and be continuing, the Debt evidenced by the Notes shall be repaid as set forth above in this Section 2.6 and the Borrower will be permitted to pay each month (i) Permitted Expenses, (ii) any of its franchise taxes or similar taxes so long as any of such taxes are not calculated on the income of the Borrower and (iii) an amount not to exceed $2,000.00 for any calendar month to Cubic or its Subsidiaries in the form of a dividend or payment of account payable from Gross Proceeds of Production delivered to the Blocked Accounts.  During the continuance of an Event of Default hereunder, the Lender, as collateral agent, may enforce such assignment and apply such revenues and proceeds of the Borrower to the payment of the Notes and the satisfaction of all other Debt to be secured by such Security Documents, such application to be made in such manner as the Lender may elect.

(l)                                     At the Lender’s sole discretion, proceeds in the Blocked Accounts may be used to pay past due Permitted Expenses or capital costs associated with the Borrower’s Oil and Gas Properties.

(m)                             All payments required pursuant to this Agreement on the Debt evidenced by the respective Notes shall be made in immediately available funds; shall be deemed received by the Lender on the next Business Day following receipt if such receipt is after 2:00 p.m. on any Business Day; and shall be made at the offices of the Lender at 1000 Louisiana, 9th Floor, Houston, Texas 77002, provided, however, the Lender may, upon notice to the Borrower, designate a different place of payment.  Whenever any payment under this Agreement or any other Loan Document shall be stated to be due on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such

21

extension of time shall in such case be included in the computation of the payment of interest.

2.7                               Interest Rates.  Principal amounts of Advances outstanding under the Notes shall bear interest at the Facility Rate (but in no event greater than the Highest Lawful Rate), calculated on the basis of a year consisting of sixty-five (365) or three hundred sixty-six (366) days, as the case may be.  Should default occur in the payment of the Notes and collection proceedings be instituted, all past due interest and principal under the Notes shall bear interest at the lesser of the Highest Lawful Rate, calculated on the basis of a year consisting of three hundred sixty-five (365) or three hundred sixty-six (366) days, as the case may be, or the Default Rate, calculated on the basis of a year consisting of three hundred sixty-five (365) or three hundred sixty-six (366) days, as the case may be, and if no Highest Lawful Rate exists, all past due interest and principal under the Notes shall bear interest at the Default Rate, calculated on the basis of a year consisting of three hundred sixty-five (365) or three hundred sixty-six (366) days, as the case may be.

2.8                               General Provisions Relating to Interest.  It is the intention of the parties hereto to comply strictly with the applicable usury Laws as in effect from time to time; and in this connection, there shall never be taken, reserved, contracted for, collected, charged or received on any Loan or any other Obligation interest in excess of that which would accrue at the Highest Lawful Rate.  To the extent that the interest rate Laws of the State of Texas are applicable to the Loans, for purposes of Chapter 303 of the Texas Finance Code, as amended, the Borrower agrees that the Highest Lawful Rate shall be the “weekly rate ceiling” as defined in such chapter, provided that the Lender may also rely, to the extent permitted by applicable Laws, on alternative maximum rates of interest under such other applicable Laws, if greater.

If under any circumstances the aggregate amount paid on the Obligations includes amounts that are by Law deemed to be interest which exceed the Highest Lawful Rate (the “excess interest”), the Borrower stipulates that such payment and collection will have been and will be deemed to have been, to the fullest extent permitted by applicable Laws, the result of mathematical error on the part of the Borrower and the Lender, and the Lender shall promptly credit the amount of such excess interest on the principal amount of the outstanding Obligations, or if the principal amount of the Obligations shall have been paid in full, refund the excess interest to the Borrower.  In the event that the maturity of the Notes is accelerated by reason of an election of the Lender resulting from any Event of Default or by reason of operation of Subsection 7.2(a), or in the event of any prepayment, then such consideration that constitutes interest under Laws applicable to the Lender may never exceed the Highest Lawful Rate, and excess interest, if any, provided for in the Notes, this Agreement or otherwise shall be cancelled automatically by the Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the principal amount of the Obligations, or if the principal amount of the Obligations shall have been paid in full, refunded by the Lender to the Borrower.

22

All sums paid, or agreed to be paid, to the Lender for the use, forbearance, and detention of the proceeds of the Loans shall, to the extent permitted by applicable Law, be amortized, prorated, allocated, and spread throughout the full term of the Obligations until paid in full so that the actual rate of interest is uniform, but does not exceed the Highest Lawful Rate, throughout the full term hereof.

2.9                               Prepayment of Term Note and PIK Note.  The Borrower shall have the right and option to prepay, at any time without premium or penalty, all or any part of the balance outstanding on the Term Note and/or the PIK Note.  Any such prepayments of Debt shall be applied first to the payment of accrued and unpaid interest on the respective Note and then to the reduction of principal.

2.10                        Net Profits Interests.  As consideration for the Loans made by the Lender pursuant to this Agreement, the Borrower agrees to convey to the Lender upon the repayment in full of the Debt evidenced by the Notes and confirmation of the title of the Lender to such interest upon conveyance by the Borrower, an undivided five percent (5%) net profits interest in the future production of hydrocarbons from or attributable to all of the Oil and Gas Properties of the Borrower, which conveyance shall be effective as of the date the Debt evidenced by the Notes is repaid in full and evidenced by an instrument substantially in the form attached hereto as Exhibit VII.

Should the Borrower elect, at any time subsequent to the conveyance of the Net Profits Interests, to sell its interest in any of its Oil and Gas Properties, then the Borrower agrees to extend to the Lender, by way of prompt written notice setting forth the terms of any such transaction, the right to sell the Net Profits Interests burdening the relevant Oil and Gas Properties to be sold by the Borrower on the same terms (including, without limitation, price based on per unit of production) as those for the sale by the Borrower.  Such right may be exercised at the sole discretion of the Lender and, should the Lender elect not to exercise such right, the Oil and Gas Properties so sold shall be conveyed by way of instrument(s) of conveyance made expressly subject to the Net Profits Interests and the provisions of this Agreement applicable thereto and shall remain subject to the Net Profits Interests.

2.11                        Increased Costs. (a)  If the Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on the Lender’s capital or on the capital of the Lender’s holding company, if any, as a consequence of this Agreement or the Loan made by such Lender to a level below that which the Lender or the Lender’s holding company could have achieved but for such Change in Law (taking into consideration the Lender’s policies and the policies of the Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to the Lender such additional amount or amounts as will compensate the Lender or the Lender’s holding company for any such reduction suffered.

(b)  A certificate of the Lender setting forth the amount or amounts necessary to compensate the Lender or its holding company, as the case may be, as specified in Subsection 2.11(a) and reasonably detailed calculations therefor shall be delivered to the

23

Borrower and shall be conclusive absent manifest error.  The Borrower shall pay the Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(c)  Failure or delay on the part of the Lender to demand compensation pursuant to this Section 2.11 shall not constitute a waiver of the Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate the Lender pursuant to this Section for any reductions incurred more than one hundred eighty (180) days prior to the date that the Lender notifies the Borrower of the Change in Law giving rise to such reductions and of the Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such reductions is retroactive, then the one hundred eighty (180) day period referred to above shall be extended to include the period of retroactive effect thereof.

2.12                        Taxes.   Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), the Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Tribunal in accordance with applicable law.

The Borrower shall pay any Other Taxes to the relevant Tribunal in accordance with applicable law.

The Borrower shall indemnify the Lender, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Lender as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Tribunal.  A certificate of the Lender as to the amount of such payment or liability under this Section and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error.

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

There is no judgment against the Borrower, nor, except as set forth on Schedule 4.5 attached hereto, is there any Litigation or other action of any nature pending before any Tribunal or, to the knowledge of the Borrower, threatened in writing against or

4.9                               Compliance with Laws.  Neither the business nor any of the activities of the Borrower as presently conducted violates any applicable Law, the result of which violation would have a Material Adverse Effect.  The Borrower possesses all licenses, approvals, registrations, permits and other authorizations necessary to enable it to carry on its businesses in all material respects as now conducted.  All such licenses, approvals, registrations, permits and other authorizations are in full force and effect.

4.10                        Proper Filing of Tax Returns and Payment of Taxes Due.  The Borrower has duly and properly filed all Tax returns which are required to be filed and has paid all Taxes due pursuant to such returns or pursuant to any assessment received, except such Taxes, if any, as are being Contested in Good Faith.

(a)                                 The Borrower has complied in all material respects with ERISA and, where applicable, the Code regarding each Plan.

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

(c)                                  No act, omission or transaction has occurred which could result in imposition on the Borrower (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to section 502(c), (i) or (1) of ERISA or a tax imposed pursuant to Chapter

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

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

8.22                        Arbitration.

(a)                                 Arbitration.  Upon the demand of any party, any dispute shall be resolved by binding arbitration (except as set forth in (e) below) in accordance with the terms of this agreement.  A “dispute” shall mean any action, dispute, claim or controversy of any kind, whether in contract or tort, statutory or common law, legal or equitable, now existing or hereafter arising under or in connection with, or in any way pertaining to, any of the loan documents, or any past, present or future extensions of credit and other activities, transactions or obligations of any kind related directly or indirectly to any of the loan documents, including without limitation, any of the foregoing arising in connection with the exercise of any self-help, ancillary or other remedies pursuant to any of the loan documents.  Any party may by summary proceedings bring an action in court to compel arbitration of a

51

dispute.  Any party who fails or refuses to submit to arbitration following a lawful demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute.

(b)                                 Governing Rules.    Arbitration proceedings shall be administered by the American Arbitration Association (“AAA”) or such other administrator as the parties shall mutually agree upon in accordance with the AAA commercial arbitration rules.  All disputes submitted to arbitration shall be resolved in accordance with the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the loan documents.  The arbitration shall be conducted at a location in Texas selected by the AAA or other administrator.  If there is any inconsistency between the terms hereof and any such rules, the terms and procedures set forth herein shall control.  All statutes of limitation applicable to any dispute shall apply to any arbitration proceeding.  All discovery activities shall be expressly limited to matters directly relevant to the dispute being arbitrated.  Judgment upon any award rendered in an arbitration may be entered in any court having jurisdiction; provided however, that nothing contained herein shall be deemed to be a waiver by any party that is a lender of the protections afforded to it under 12 U.S.C. 91 or any similar applicable state law.

(c)                                  No Waiver; Provisional Remedies, Self-Help And Foreclosure.  No provision hereof shall limit the right of any party to exercise self-help remedies such as setoff, foreclosure against or sale of any real or personal property collateral or security, or to obtain provisional or ancillary remedies, including without limitation injunctive relief, sequestration, attachment, garnishment or other appointment of a receiver, from a court of competent jurisdiction before, after or during the pendency of any arbitration or other proceeding.  The exercise of any such remedy shall not waive the right of any party to compel arbitration hereunder.

(d)                                 Arbitrator Qualifications And Powers; Awards.  Arbitrators must be active members of the Texas state bar with expertise in the substantive laws applicable to the subject matter of the dispute.  Arbitrators are empowered to resolve disputes by summary rulings in response to motions filed prior to the final arbitration hearing.  Arbitrators (i) shall resolve all disputes in accordance with the substantive law of the state of Texas, (ii) may grant any remedy or relief that a court of the state of Texas could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award, and (iii) shall have the power to award recovery of all costs and fees, to impose sanctions and to take such other actions as they deem necessary to the same extent a judge could pursuant to the federal rules of civil procedure, the Texas rules of civil procedure or other applicable law.  Any dispute in which the amount in controversy is $5,000,000 or less shall be decided by a single arbitrator who shall not render an award of greater than $5,000,000 (including damages, costs, fees and expenses).  By submission to a single arbitrator, each party expressly waives any right or claim to recover more than $5,000,000.  Any dispute in which the amount in controversy exceeds $5,000,000 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations.

(e)                                  Judicial Review.  Notwithstanding anything herein to the contrary, in any arbitration in which the amount in controversy exceeds $25,000,000, the arbitrators shall be required to make specific, written findings of fact and conclusions of law.  In such arbitrations (i) the arbitrators shall not have the power to make any award which is not supported by substantial evidence or which is based on legal error, (ii) an award shall not be binding upon the parties unless the findings of fact are supported by substantial evidence and the conclusions of law are not erroneous under the substantive law of the state of Texas, and (iii) the parties shall have in addition to the grounds referred to in the federal arbitration act for vacating, modifying or correcting an award the right to judicial review of (a) whether the findings of fact rendered by the arbitrators are supported by substantial evidence, and (b) whether the conclusions of law are erroneous under the substantive law of the state of Texas.  Judgment confirming an award in such a proceeding may be entered only if a court determines the award is supported by substantial evidence and not based on legal error under the substantive law of the state of Texas.

(f)                                   Miscellaneous.  To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA.  No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business, by applicable law or regulation, or to the extent necessary to exercise any judicial review rights set forth herein.  If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the loan documents or the subject matter of the dispute shall control.  This arbitration provision shall survive termination, amendment or expiration of any of the loan documents or any relationship between the parties.

8.23                        USA Patriot Act Notice.  The Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub.
