      Re: Loan Agreement

Ladies and Gentlemen:

     This letter sets forth the Loan Agreement (this “ Loan Agreement ”) among Infinity Energy Resources, Inc. (“ Borrower ”), a Delaware corporation; Infinity Oil and Gas of Texas, Inc., a Delaware corporation, and Infinity Oil & Gas of Wyoming, Inc., a Wyoming corporation (collectively “ Guarantors ”); and Amegy Bank N.A. (“ Lender ”), with respect to loans from Lender to Borrower and obligations of Borrower and Guarantors to Lender.

      Loan . (a) Subject to the terms and conditions set forth in this Loan Agreement and the other agreements, instruments, and documents executed and delivered in connection herewith (collectively the “ Loan Documents ”), Lender agrees to make a revolving loan in the maximum amount of $50,000,000.00 to Borrower (the “ Revolving Loan ”) on the terms set forth in the Revolving Promissory Note attached as Exhibit A (the “ Revolving Note ”), for the purposes set forth below. Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow on a revolving basis from time to time during the period commencing on the date hereof and continuing through 11:00 a.m. (Dallas, Texas time) on January 9, 2009 (the “ Termination Date ”), such amounts as Borrower may request under the Revolving Loan; provided, however, the total principal amount outstanding at any time shall not exceed the lesser of (i) the aggregate sums permitted under the Borrowing Base (as defined below), which is initially set at $27,000,000.00, or (ii) $50,000,000.00. All sums advanced under the Revolving Loan, together with all accrued but unpaid interest thereon, shall be due and payable in full on the Termination Date. Borrower has the right to request a one year extension of the Termination Date in connection with the October 1 Borrowing Base redetermination each year. Any extension is subject to appropriate credit approval of Lender and may be subject to additional conditions. Lender has not yet committed to any extension of the Termination Date.

          (b) The unpaid principal balance of the Revolving Note shall bear interest from the date advanced until paid or until default or maturity at the rates per annum elected by Borrower from the following options under the terms of the Revolving Note: (i) the sum of the

Infinity Energy Resources, Inc.

Stated Rate plus the Applicable Margin, or (ii) the sum of the LIBOR Rate plus the LIBOR Spread; provided that in no event shall such rate exceed the Maximum Rate (as defined below). The Applicable Margin and the LIBOR Spread will vary based on the Borrowing Base Utilization (as defined below) as in effect from time to time, with each change in the applicable rate resulting from a change in the Borrowing Base Utilization to take effect on the day such change in the Borrowing Base Utilization occurs. “ Borrowing Base Utilization ” is defined as an amount expressed as a percentage, equal to the quotient of (i) the sum of (A) the aggregate principal amount of the Revolving Loan outstanding, plus (B) the aggregate undrawn amount of all outstanding Letters of Credit (as defined below), divided by (ii) the Borrowing Base. Based on the Borrowing Base Utilization, the Applicable Margin and the LIBOR Spread will vary as set forth below:

The “ Stated Rate ” shall be equal to the greater of (i) the interest rate publicly announced by Lender from time to time as its general reference rate of interest, which prime rate shall change upon any change in such announced or published general reference interest rate and which prime rate may not be the lowest interest rate charged by the Lender, or (ii) the sum of the rate of interest, then most recently published in the Money Rates section of The Wall Street Journal as the “federal funds” rate for reserves traded among commercial banks for overnight use, plus one-half of one percent (0.5 %); and the “ LIBOR Rate ” means the rate of interest per annum (rounded upwards, if necessary, to the nearest 1/16 of 1%) equal to the average of the offered quotations appearing at Page or Ticker US0001M, US0002M, US0003M, or US0006M, as the case may be for the applicable Interest Period (as defined in the Revolving Note) in Bloomberg Financial Markets Commodities News as published by Bloomberg L.P. (or such other similar news reporting service as Lender may subscribe to at the time such LIBOR Rate is determined), at which deposits in U.S. dollars are offered by the major London clearing banks in the London interbank offered market for a period of time equal or comparable to one, two, three, or six months and in an amount equal to or comparable to the principal amount of the LIBOR Balance (as defined in the Revolving Note) to which such interest period relates.

          (c) Advances on the Revolving Loan may be used only for the following purposes: (i) for the Closing Date Advances (as defined below), (ii) for the Approved Plan of Development (as defined below), (iii) the issuance of Letters of Credit (as defined below), (iv) auction letters and letters of guarantee; and (v) for other business purposes approved by Lender in advance. On or after the date of the closing of this Loan Agreement, Borrower may request advances on the Revolving Loan for the following purposes only (the “ Closing Date

Infinity Energy Resources, Inc.
January 9, 2007
Page 3 of 32

Advances ”):

               (i) Borrower may advance up to $8,000,000.00 for the purpose of paying Borrower’s and Guarantors’ past-due accounts payable (the “ Accounts Payable ”);

               (ii) Borrower may advance on the Revolving Loan to pay closing costs, expenses, and fees incurred in connection with this Loan Agreement; and

               (iii) Borrower may advance up to $500,000.00 for working capital.

          (d) Except for the Closing Date Advances, all subsequent advances on the Revolving Loan shall be used only to fund the budgeted capital expenditures under the Approved Plan of Development. As used in this Loan Agreement, “ Approved Plan of Development ” means the written and scheduled plan of development approved by Lender, with respect to budgeted capital expenditures and expected schedule for Guarantors’ development activities with respect to those proved oil and gas properties and undeveloped oil and gas properties in Comanche and Erath Counties, Texas, Routt County, Colorado, and Sweetwater County, Wyoming (the “ Project Areas ”). The initial Approved Plan of Development approved by Lender is attached as Schedule 1(d) to this Loan Agreement. The Approved Plan of Development may not be materially modified without Lender’s prior written consent. If Borrower wishes to so modify the Approved Plan of Development, Borrower shall provide an amended Plan of Development for Lender’s approval at least ten (10) days before it is proposed to be effective; and Lender must respond to such request for written consent within such ten-day period. Borrower and Guarantors shall use all “Free Operating Cash Flow” (as defined below) for the purpose of funding the capital expenditures under the Approved Plan of Development.

          (e) At the request of Borrower, Lender may from time to time issue one or more letters of credit for the account of Borrower, Guarantors, or any affiliates (the “ Letters of Credit ”). Borrower’s availability on the Revolving Loan will be reduced by the aggregate undrawn amount of all unexpired Letters of Credit. Any fundings under any Letters of Credit will be treated as an advance on the Revolving Loan and will be secured by the Security Documents (as defined below). At no time may the aggregate undrawn amount of all outstanding Letters of Credit exceed twenty percent (20%) of the Borrowing Base. All Letters of Credit shall be for a term of up to one year (or longer if necessary for regulatory requirements) but shall expire not later than five days prior to the Termination Date, unless adequately secured by cash collateral held by Lender. Borrower will sign and deliver Lender’s customary forms for the issuance of Letters of Credit. Borrower agrees to pay to Lender a Letter of Credit Fee equal to the Letter of Credit Fee Rate per annum set forth below, calculated on the aggregated stated amount of each Letter of Credit for the stated duration thereof (computed on the basis of actual days elapsed as if each year consisted of 360 days). The Letter of Credit Fee Rate will vary as set forth below based on the Borrowing Base Utilization:

Any renewal or extension of a Letter of Credit will be treated as a new issuance for the purpose of the Letter of Credit Fee. These Letter of Credit Fees are payable quarterly in arrears within fifteen (15) days of the end of each calendar quarter.

          (f) At the request of Borrower and in the sole discretion of Lender, Lender may from time to time issue one or more auction letters or letters of guarantee in connection with auctions or other purchases of oil and gas properties by Borrower. Each auction letter and letter of guarantee will have an expiration date not longer than five (5) days from the date of the letter. Notwithstanding any provision to the contrary, Borrower’s availability on the Revolving Loan will be reduced by the aggregate maximum amount stated in all unexpired auction letters and letters of guarantee until Lender is satisfied that (i) Borrower was unsuccessful in the auction or purchase, or (ii) Borrower consummates the purchase of the oil and gas properties. Any fundings pursuant to an auction letter or letter of guarantee will be treated as an advance on the Revolving Loan and will be secured by the Security Documents.

          (g) Borrower agrees to pay to Lender the following fees that are non-refundable and earned by Lender upon execution of this Loan Agreement unless otherwise stated:

               (i) Upon execution of the term sheet, Borrower previously paid Lender a Due Diligence Fee in the amount of $50,000.00.

               (ii) Upon execution of this Loan Agreement, Borrower agrees to pay Lender an Arrangement Fee in the amount of $270,000.00; provided, however, that the Due Diligence Fee shall be credited to this Arrangement Fee at closing.

               (iii) Borrower agrees to pay to Lender a Non-Use Fee equal to the applicable Non-Use Fee Rate set forth below per annum (computed on the basis of actual days elapsed and as if each calendar year consisted of 360 days), payable quarterly in arrears, multiplied by an amount determined daily equal to the difference between the Borrowing Base and the sum of (i) the aggregate outstanding principal balance of the Revolving Loan at such time, plus (ii) the aggregate undrawn amount on all outstanding Letters of Credit. The Non-Use Fee Rate will vary as set forth below based on the Borrowing Base Utilization:

This Non-Use Fee is payable quarterly within fifteen (15) days of the end of each calendar quarter.

          (h) The Revolving Loan, all other loans now or hereafter made by Lender to Borrower, and any renewals or extensions of or substitutions for those loans, will be referred to collectively as the “ Loans .” The Revolving Note, all other promissory notes now or hereafter payable by Borrower to Lender, and any renewals or extensions of or substitutions for those notes, will be referred to collectively as the “ Notes .”

     2.  Collateral . (a) Payment of the Notes and the Hedge Liabilities (as defined below) will be secured by the first liens and first security interests, subject to Permitted Encumbrances (as defined below) created or described in the following (collectively the “ Security Documents ”): (i) a Deed of Trust and Security Agreement of even date, executed by Infinity Oil and Gas of Texas, Inc., in favor of Lender, and covering oil and gas properties located in Erath and Comanche Counties, Texas; (ii) a Deed of Trust and Security Agreement of even date, executed by Infinity Oil & Gas of Wyoming, Inc. in favor of Lender, and covering oil and gas properties located in Routt County, Colorado; (iii) a Deed of Trust and Security Agreement of even date, executed by Infinity Oil & Gas of Wyoming, Inc. in favor of Lender, and covering oil and gas properties located in Sweetwater County, Wyoming; and (iv) any other security documents now or hereafter executed in connection with the Loans. The three deeds of trust described above shall collectively be referred to as the “ Deeds of Trust ”; and all oil and gas properties now or hereafter mortgaged to Lender by Borrower or Guarantors, including the oil and gas properties covered by the Deeds of Trust, will be referred to as the “ Properties .” If requested by Lender, Borrower and Guarantors will execute in favor of Lender mortgages, deeds of trust, security agreements, or amendments, in Proper Form (as defined below), mortgaging any additional oil and gas properties and all additional interests in the Properties acquired by Borrower or Guarantors so that Lender will continuously maintain under mortgage not less than ninety percent (90%) of the aggregate present value (as calculated by Lender in its sole discretion in accordance with the methods set forth below for the Borrowing Base) assigned to Borrower’s and Guarantors’ oil and gas properties based upon Lender’s in-house evaluation.

          (b) Payment of the Notes and the Hedge Liabilities will also be guaranteed by each of the Guarantors pursuant to Commercial Guaranties in Proper Form (collectively the “ Guaranties ”).

          (c) In connection with the Deeds of Trust and at such time as Lender requires Borrower to mortgage additional oil and gas properties, Borrower and Guarantors shall, upon request of Lender, deliver to Lender title opinions and/or other title information acceptable to Lender covering at least eighty-one percent (81%) of the present value (as determined by Lender in the manner set forth for Borrowing Base determinations below) of the Properties and the oil and gas properties which are to become Properties, along with such other information regarding title as Lender shall reasonably request, all in Proper Form and from attorneys or landmen acceptable to Lender. Lender reserves the right to immediately exclude any oil and gas property from the Borrowing Base if Lender learns of any material title issue with respect to the oil and gas property or if Lender’s review of Borrower’s and Guarantors’ title to the oil and gas property indicates that Borrower’s title is unacceptable to Lender, in its sole discretion.

          (d) During the continuance of an Event of Default (as defined below), Lender reserves the right to require Borrower and Guarantors to set up a lockbox account to be managed by Lender for the purpose of collection of production proceeds attributable to Borrower’s and Guarantors’ interest in the Properties. Borrower and Guarantors agree that upon Lender’s election to require the lockbox after an Event of Default, Lender will receive the proceeds of oil and gas produced from or attributable to Borrower’s and Guarantors’ interest in the Properties for application as set forth in Section 3.2 of the Deed of Trust; and Borrower and Guarantors hereby direct all production purchasers or operators distributing proceeds to pay Borrower’s and Guarantors’ distributions attributable to Borrower’s and Guarantors’ interest in the Properties directly to Lender, if Lender so elects. All production proceeds attributable to the Properties received in the lockbox account by Lender with respect to production, severance, ad valorem, or other taxes on production proceeds (excluding income taxes) or that are attributable to another person’s or entities’ interest in the Properties shall be released immediately to Borrower upon Borrower’s request. All production proceeds attributable to Borrower’s and Guarantors’ interest in the Properties received in the lockbox account by Lender in excess of the current scheduled monthly payment and any other fees or expenses owed to Lender will be transferred to Borrower at the end of each month for its use consistent with the provisions of this Loan Agreement, so long as there is no existing Event of Default. If the production proceeds attributable to Borrower’s and Guarantors’ interest in the Properties received by Lender during any month are not sufficient to make the scheduled monthly payment, Borrower will pay Lender the deficiency within ten (10) days of notice from Lender of such shortfall. Contemporaneously with the execution of this Loan Agreement, Guarantors will sign and deliver to Lender letters in lieu of transfer orders to all purchasers of production directing those parties to pay all proceeds attributable to Guarantors’ interest in the Properties to the lockbox account, and these letters, signed in blank, will be held by Lender until such time as Lender elects to require the lockbox after an Event of Default.

          (e) Unless a security interest would be prohibited by law or would render a nontaxable account taxable, Borrower and Guarantors grant to Lender a contractual possessory security interest in, and hereby assigns, pledges, and transfers to Lender all of Borrower’s and Guarantors’ rights in any deposits or accounts now or hereafter maintained with Lender (whether checking, savings, or any other account), excluding, however, accounts maintained by Borrower and Guarantors at Lender for the purpose of revenue distribution to third parties entitled to those revenues, including payroll accounts and any other accounts held by Borrower or Guarantors for the benefit of a third party. While an Event of Default is outstanding, Borrower and Guarantors authorize Lender, to the extent permitted by applicable law, to charge or setoff any sums owing on the Loans or the Hedge Liabilities against any and all such deposits and accounts; and Lender shall be entitled to exercise the rights of offset and banker’s lien against all such accounts and other property or assets of Borrower and Guarantors with or in the possession of Lender to the extent of the full amount of the Loans and the Hedge Liabilities.

     3.  Borrowing Base . (a) On or about April 1 and October 1 of each year, commencing April 1, 2007, Lender may determine or redetermine, in its sole discretion, a Borrowing Base. In addition, Lender may require an unscheduled redetermination once during each six month period, and Borrower shall have the right to request an unscheduled redetermination of the Borrowing Base by Lender once per six-month period between scheduled redeterminations, and Lender shall conduct such redetermination using the methods described in this section. The term “ Borrowing Base ” refers to the designated loan value (as calculated by Lender in its sole discretion) assigned to the discounted present value of future net income accruing to Borrower’s and Guarantors’ oil and gas properties (and related gathering systems and processing and plant operations) based upon Lender’s in-house evaluation. Lender’s determination of the Borrowing Base will use such methodology, assumptions, and discount rates customarily used by Lender with respect to credits of a similar size and nature in assigning collateral value to oil and gas properties and will be based upon such other credit factors or financial information available to Lender at the time of each determination, including, without limitation, current market conditions and Borrower’s and Guarantors’ assets, liabilities, cash flow, liquidity, business, properties, prospects, management, and ownership. Borrower and Guarantors acknowledge that increases in the Borrowing Base are subject to appropriate credit approval by Lender.

          (b) The outstanding principal balance owing on the Revolving Note, plus the aggregate undrawn amount of all Letters of Credit, may not exceed the Borrowing Base at any time, subject to the payout provisions below in the event of a Borrowing Base decrease. A decrease in the Borrowing Base will result in an immediate decrease in Lender’s commitment under the Revolving Loan. If the redetermined Borrowing Base is less than the sum of the outstanding principal then owing on the Revolving Note, plus the aggregate undrawn amount of all Letters of Credit, Lender will notify Borrower of the amount of the Borrowing Base and the amount of the deficiency. Within thirty (30) days after notice is sent by Lender, Borrower shall remedy the deficiency by either: (i) making a lump sum payment on the Revolving Note

Infinity Energy Resources, Inc.

to reduce the principal outstanding plus Letters of Credit to an amount equal to or less than the new Borrowing Base; (ii) committing to make six equal monthly installment payments to reduce the principal plus Letters of Credit to an amount equal to or less than the new Borrowing Base; or (iii) mortgaging additional collateral, which must be acceptable to Lender as to type, value, and title.

          (c) At the time of any redetermination, Lender reserves the right to establish an equal Monthly Commitment Reduction (“ MCR ”) amount by which the Borrowing Base shall be automatically reduced effective as of the fifth (5 ^th ) day of each successive calendar month until the next Borrowing Base redetermination. Lender’s determination of the MCR will use such methodology, assumptions, and discount rates customarily used by Lender with respect to credits of a similar size and nature in determining commitment reductions and will be based upon such other credit factors or financial information available to Lender at the time of each determination, including, without limitation, the economic half-life of the Properties, and Borrower’s and Guarantors’ assets, liabilities, cash flow, liquidity, business, properties, prospects, management, and ownership. The MCR will initially be set at zero dollars ($0). If the outstanding principal balance owing on the Revolving Note, plus the aggregate undrawn amount of all unexpired and outstanding Letters of Credit, shall exceed the Borrowing Base solely because of an MCR reduction, Borrower shall within ten (10) days of such event make a single lump sum payment in an amount not to exceed the MCR to reduce the sum of the outstanding principal balance owing on the Revolving Note, plus the aggregate undrawn amount of all unexpired and outstanding Letters of Credit, to an amount below the Borrowing Base. If the outstanding principal balance owing on the Revolving Note, plus the aggregate undrawn amount of all unexpired and outstanding Letters of Credit, shall exceed the Borrowing Base because of a Borrowing Base redetermination (or a Borrowing Base redetermination combined with a required MCR), Borrower shall have the right to cure set forth in subsection (b) above; provided, however, that if the MCR was applicable before the Borrowing Base redetermination, then the MCR amount will be due in a lump sum within ten (10) days of notice from Lender and Lender may continue the MCR at the same amount or change the MCR effective on the redetermination date.

          (d) If Borrower or Guarantors sell, transfer, or otherwise dispose of any oil and gas properties included in the Borrowing Base that have an aggregate sales price in excess of five percent (5%) of the most recent Borrowing Base in any fiscal year, Lender reserves the right to redetermine the Borrowing Base in accordance with this Section 3, which redetermination will be in addition to any special redeterminations permitted to Lender under subsection (a) above. Any Borrowing Base deficiency resulting from the sale of any oil and gas properties shall be immediately reduced by a single lump sum payment in an amount not to exceed the net proceeds from the sale of the oil and gas properties, and any remaining deficiency after the Borrowing Base redetermination shall be cured by Borrower pursuant to subsection (b) above.

Upon payment in full of the Notes and termination of any obligation of Lender to make further advances on the Revolving Loan, and upon either termination of all Hedge Transactions with Lender or Hedge Provider or Borrower and Guarantors providing appropriate support and security for then-outstanding Hedge Liabilities on terms satisfactory to Lender in its sole discretion, including substitution on the outstanding Hedge Transactions on terms acceptable to Lender of a counterparty meeting the requirements of Section 4(e)(iv) below and that is otherwise acceptable to Lender (such liabilities to thereafter be deemed “ Supported Hedge Liabilities ”), this Loan Agreement may be terminated and the Security Documents released.

          (c) Security. Borrower and Guarantors agree that the Security Documents shall secure payment of all Hedge Liabilities. Borrower, Guarantors, and Lender hereby agree that the Loans and the Hedge Liabilities shall rank pari passu and shall collectively be secured by the Security Documents on a pro rata basis. Lender shall hold the Properties and all related collateral under the Security Documents, along with all payments and proceeds arising therefrom, for the benefit of Lender, as security for the payment of all Loans and as security for all Hedge Liabilities on a ratable basis. The benefit of the Security Documents and of the provisions of this Loan Agreement relating to the collateral shall also extend to and be available to Lender and Hedge Provider to the extent either is a counter-party to any Hedge Transactions on a pro rata basis with respect to any obligations, liabilities, or indebtedness of Borrower or Guarantors.

          (d) Termination. If and to the extent any Hedge Transaction is used in calculation of the Borrowing Base, such Hedge Transaction cannot be cancelled, liquidated, or “unwound” without the prior written consent of Lender.

          (e) Hedging Limitations . Borrower and Guarantors shall not enter into any Hedge Transaction related to crude oil, natural gas, or other commodities, except hedging required by Lender and except for Hedge Transactions which meet the following requirements:

               (i) Hedge Transactions resulting in a cap on the price to be received by Borrower and Guarantors, involving in the aggregate at any time not more than eighty percent (80%) of Guarantors’ anticipated production from their proved developed producing oil and gas properties (as forecast in Lender’s most recent engineering valuation of the Properties); provided, however, that (1) Hedge Transactions relating to oil volumes from the Wolf Mountain 15-2-7-87 well in Routt County, Colorado, shall be limited to not more than forty percent (40%) of Guarantors’ anticipated production from that well until such time as the well constitutes twenty percent (20%) or less of the total present value of Guarantors’ proved developed producing oil and gas properties (as forecast in Lender’s most recent engineering valuation of

Infinity Energy Resources, Inc.

Page 11 of 32

the Properties), and (2) there shall be no limitation on the volume of Hedge Transactions resulting only in a floor price per barrel or mcf; and

               (ii) Hedge Transactions that would not result in a fixed price per barrel or mcf lower than the base case price used by Lender in the most-recent engineering evaluation of Guarantors’ oil and gas properties, adjusted for variances between the hedging price and Guarantors’ actual product price as determined by Lender, in each case as disclosed by Lender to Borrower, or otherwise at hedging prices acceptable to Lender as disclosed to Borrower; and

               (iii) Hedge Transactions that are each for a period not to exceed forty-eight (48) months; and

               (iv) To the extent that Lender requires Hedge Transactions in connection with a Borrowing Base, Hedge Transactions where, in each case, the underlying contracts are with Lender or Hedge Provider, as counterparty, with a counter-party (or the parent entity thereof) who at the time the contract is made has long-term obligations rated BBB or better by Standard & Poor’s Ratings Group or Baa or better by Moody’s Investors Services, Inc., or with a counter-party that is otherwise approved by Lender in writing; and

               (v) Hedge Transactions that are not effective at concurrent or overlapping periods of time on the same volumes of production on both a physical and financial basis, unless the combined volumes are in compliance with the volume limitations set forth above.

Borrower may enter into swaps, collars, floors, caps, options, corridors, or other contracts, as such terms are commonly known within the capital markets, which are intended to reduce or eliminate the risk of fluctuation in interest rates for the purpose and effect of fixing and capping interest rates on a principal amount of indebtedness of Borrower; provided that (A) the floating rate index of each such contract generally matches the index used to determine the floating rates of interest on the corresponding indebtedness of Borrower to be hedged by such contract and the interest rate exposure would not cause the notional amount of all such Hedge Transactions then in effect for the purpose of hedging interest rate exposure to exceed one hundred percent (100%) of the total consolidated indebtedness of Borrower projected to be outstanding for any period covered by such Hedge Transaction, and (B) Borrower shall not establish or maintain any margin accounts with respect to such contracts.

          (f) Required Hedges . On or before three (3) business days after the date of this Loan Agreement, Guarantors will enter into Hedge Transactions covering crude oil and natural gas meeting the following requirements: (i) Hedge Transactions resulting in at least seventy percent (70%) of Guarantors’ anticipated production from their proved developed producing oil and gas properties (as forecast in Lender’s most recent engineering valuation of the Properties) in the aggregate; (ii) Hedge Transactions for a period of not less than forty-eight (48) months; (iii) Hedge Transactions resulting in a fixed price or floor price per barrel or mcf

          (g) Speculation . Borrower and Guarantors shall not invest for speculative purposes in any Hedge Transactions or in any other options, futures, or derivatives.

          (h) Additional Collateral . If a Hedge Transaction is entered into with an outside counter-party, Borrower and Guarantors shall, if requested by Lender, collaterally assign and pledge in favor of Lender a first-priority continuing security interest in the applicable trading account and the hedging contract as additional security for the Loans. In connection therewith, Borrower and Guarantors shall execute and deliver to Lender such security agreements, control agreements, and financing statements as deemed appropriate by Lender to create and perfect the continuing security interest therein.

     5.  Conditions Precedent . (a) The obligation of Lender to make the initial advance on the Revolving Loan is subject to Borrower’s satisfaction, in Lender’s sole discretion, of the following conditions precedent:

               (1) Lender’s receipt and satisfactory review by Lender of the September 30, 2006 financial statements of Borrower and Guarantors, on a consolidated and consolidating (except for the cash flow statement) basis, including a balance sheet, a statement of operations, and a cash flow statement, prepared in conformity with generally accepted accounting principles in effect on the date such statement was prepared, consistently applied (“ GAAP ”).

     (b) Upon any event described in Subsection 10 (a)(1) above regarding payment of sums owing to Lender, Lender shall provide Borrower with an invoice for the payment due and Borrower shall have five (5) days grace after the due date in order to cure the default prior to acceleration of the Notes and exercise of any remedies.

     (c) All rights of Lender under the terms of this Loan Agreement shall be cumulative of, and in addition to, the rights of Lender under any and all other agreements between Borrower and Lender (including, but not limited to, the other Loan Documents), and not in substitution or diminution of any rights now or hereafter held by Lender under the terms of any other agreement.

     12.  Waiver and Amendment . Neither the failure nor any delay on the part of Lender to exercise any right, power, or privilege herein or under any of the other Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power, or privilege preclude any other or further exercise thereof or the exercise of any other right, power, or privilege. No waiver of any provision in this Loan Agreement or in any of the other Loan Documents and no departure by Borrower therefrom shall be effective unless the same shall be in writing and signed by Lender, and then shall be effective only in the specific instance and for the purpose for which given and to the extent specified in such writing. No modification or amendment to this Loan Agreement or to any of the other Loan Documents shall be valid or effective unless the same is signed by the party against whom it is sought to be enforced.

     13.  Savings Clause .

In the event that Lender ever receives, collects, or applies as interest any such excess, the amount which would be excessive interest will be applied to the reduction of the principal balances of the Notes, and, if the principal balances of the Notes are paid in full, any remaining excess shall forthwith be paid to Borrower.

In determining whether the interest paid or payable exceeds the Maximum Rate (or any other interest amount which might in any way be deemed usurious), Borrower and Lender shall, to the maximum extent permitted under applicable law: (i) characterize any non-principal payment (other than payments which are expressly designated as interest payments hereunder) as an expense or fee rather than as interest; (ii) exclude voluntary prepayments and the effect thereof; and (iii) amortize, pro rate, or spread the total amount of interest throughout the entire contemplated term of the Notes so that the interest rate is uniform throughout the term. The term “ Maximum Rate ” means the maximum interest rate which may be lawfully charged under applicable law.

      Definitions. For purposes of this Note, unless the context otherwise requires, certain terms used herein shall be defined as follows:

     “ Interest Notice ” means the notice given by Borrower to Lender of an Interest Option selected hereunder.

Revolving Promissory Note — Page 2 of 10

     “ LIBOR Spread ” means the “LIBOR Spread” as defined in the Loan Agreement; and the LIBOR Spread will vary as set forth in the Loan Agreement, based on the Borrowing Base Utilization (as defined in the Loan Agreement) as in effect from time to time, with each change in the applicable percentage resulting from a change in the Borrowing Base Utilization to take effect on the day such change in the Borrowing Base Utilization occurs.

     “ Loan Agreement ” means the Loan Agreement of even date, by and among Borrower, Lender, and others, as amended.

     “ Maximum Rate ” means at the particular time in question the maximum rate of interest which, under applicable law, may then be charged on this Note.

If applicable law ceases to provide for a maximum rate of interest, the Maximum Rate shall be equal to eighteen percent (18%) per annum.

     “ Stated Rate ” means the greater of (i) the interest rate publicly announced by Lender from time to time as its general reference rate of interest, which prime rate shall change upon any change in such announced or published general reference interest rate and which prime rate may not be the lowest interest rate charged by the Lender, or (ii) the sum of the rate of interest, then most recently published by The Wall Street Journal as the “federal funds” rate for reserves traded among commercial banks for overnight use, plus one half of one percent (0.5%).

     “ Stated Rate Balance ” means the principal balance of this Note bearing interest at a rate based upon the Adjusted Stated Rate.

      Payments of Interest and Principal. The principal of and all accrued but unpaid interest on this Note shall be due and payable as follows:

     (a) accrued, unpaid interest on this Note shall be due and payable on each Interest Payment Date, commencing on the first (1 ^st ) day of February, 2007, and continuing until the Maturity Date;

     (b) the principal of this Note shall be due and payable as required by the Loan Agreement to meet any Borrowing Base deficiency or Monthly Commitment Reductions (if and when required by Lender under the Loan Agreement); and

     (c) the outstanding principal balance of this Note, together with all accrued but unpaid interest, shall be due and payable on the Maturity Date.

      Revolving Credit. Under the Loan Agreement, Borrower may request advances and make payments hereunder from time to time, provided that it is understood and agreed that the aggregate principal amount outstanding from time to time hereunder shall not at any time exceed the Total Principal Amount or the Borrowing Base (as defined in the Loan Agreement), subject to the right to cure Borrowing Base deficiencies in the Loan Agreement. In addition, Lender may set a monthly commitment reduction pursuant to the Loan Agreement, and thereafter the Borrowing Base and

Revolving Promissory Note — Page 3 of 10

Lender’s commitment under this Note will decline monthly and the amount outstanding under this Note may not exceed this declining Borrowing Base as and to the extent provided in the Loan Agreement. The unpaid balance of this Note shall increase and decrease with each new advance or payment hereunder, as the case may be. This Note shall not be deemed terminated or canceled prior to the Maturity Date, although the entire principal balance hereof may from time to time be paid in full. Borrower may borrow, repay and reborrow hereunder. Unless otherwise agreed to in writing or otherwise required by applicable law, payments will be applied first to unpaid accrued interest, then to principal, and any remaining amount to any unpaid collection costs, delinquency charges, and other charges; provided, however, while an Event of Default (as defined below) is outstanding, Lender reserves the right to apply payments among principal, interest, delinquency charges, collection costs, and other charges, in such order and manner as the holder of this Note may from time to time determine in its sole discretion. All payments and prepayments of principal of or interest on this Note shall be made in Dollars in immediately available funds, at the address of Lender indicated above, or such other place as the holder of this Note shall designate in writing to Borrower. If any payment of principal of or interest on this Note shall become due on a day which is not a Business Day or LIBOR Business Day, as applicable, such payment shall be made on the next succeeding Business Day or LIBOR Business Day, as applicable, and any such extension of time shall be included in computing interest in connection with such payment. The books and records of Lender shall be prima facie evidence of all outstanding principal of and accrued and unpaid interest on this Note.

      Accrual of Interest. The unpaid principal of the Stated Rate Balance shall bear interest at a rate per annum which shall from day to day be equal to the lesser of (i) the Adjusted Stated Rate, or (ii) the Maximum Rate. The unpaid principal of each LIBOR Balance shall bear interest at a rate per annum which shall be equal to the lesser of (i) the Adjusted LIBOR Rate for the Interest Period in effect with respect to such LIBOR Balance, or (ii) the Maximum Rate. Each change in the Adjusted Stated Rate shall become effective without prior notice to Borrower automatically as of the opening of business on the date of such change in the Adjusted Stated Rate. Interest on this Note shall be calculated on the basis of the actual days elapsed, but computed as if each year consisted of 360 days.

      Interest Options. Subject to the provisions hereof, Borrower shall have the option (the “ Interest Option ”) of having the unpaid principal balance of this Note bear interest at the Adjusted LIBOR Rate or the Adjusted Stated Rate; provided, however, that only four (4) Interest Period options shall be in effect at any one time during the term hereof and the selection of the Adjusted LIBOR Rate for a particular Interest Period shall be for no less than $1,000,000.00 of unpaid principal and in even multiples of $100,000.00 in principal. The Interest Option shall be exercised in the manner provided below:

     (a)  Advances . Each advance on the Note will initially be funded as a Stated Rate Balance and will accrue interest from the date advanced at the Adjusted Stated Rate.

     (b)  Conversion From Adjusted Stated Rate . During any period in which the principal hereof bears interest at the Adjusted Stated Rate, Borrower shall have the right, on any LIBOR Business Day (the “ Conversion Date ”), to convert all or part of the principal balance owed on the

Revolving Promissory Note — Page 4 of 10

Note from the Stated Rate Balance to a LIBOR Balance by giving Lender an Interest Notice of such selection at least two (2) LIBOR Business Days prior to the Conversion Date.

     (c)  At Expiration of Interest Periods . At least two (2) LIBOR Business Days prior to the termination of each Interest Period, Lender shall receive from Borrower an Interest Notice indicating the Interest Option to be applicable to the corresponding LIBOR Balance upon the expiration of such Interest Period. If the required Interest Notice shall not have been timely received by Lender, Borrower shall be deemed to have selected the Adjusted Stated Rate to be applicable to the corresponding LIBOR Balance upon the expiration of the Interest Period and to have given Lender notice of such selection.

      Interest Recapture. If on each Interest Payment Date or any other date on which interest payments are required hereunder, Lender does not receive interest on this Note computed at the Adjusted Stated Rate or Adjusted LIBOR Rate because such Contract Rate exceeds or has exceeded the Maximum Rate, then Borrower shall, upon the written demand of Lender, pay to Lender in addition to the interest otherwise required to be paid hereunder, on each Interest Payment Date thereafter, the Excess Interest Amount (calculated as of such later Interest Payment Date); provided that in no event shall Borrower be required to pay, for any Interest Period, interest at a rate exceeding the Maximum Rate effective during such period.

      Interest on Past Due Amounts and Default Interest. To the extent any interest is not paid on or before the date it becomes due and payable, Lender may, at its option, add such accrued but unpaid interest to the principal of this Note. Notwithstanding anything herein to the contrary, (i) while any Event of Default (as defined below) is outstanding, (ii) upon acceleration of the maturity hereof following an uncured Event of Default, or (iii) at the Maturity Date, all principal of this Note shall, at the option of Lender, bear interest until paid at the lesser of (i) the sum of the Stated Rate plus six percent (6.0%) per annum, or (ii) the Maximum Rate.

      Loan Agreement/Security. This Note is subject to the terms and provisions of the Loan Agreement. In the event of any conflict or inconsistency between this Note and the Loan Agreement, the Loan Agreement shall govern. This Note is secured by all liens and security interests described in the Loan Agreement. This Note, the Loan Agreement, and all other documents evidencing, securing, governing, guaranteeing, or pertaining to this Note are hereinafter collectively referred to as the “ Loan Documents .” The holder of this Note is entitled to the benefits and security provided in the Loan Documents.

      Prepayments; Consequential Loss. Borrower may from time to time prepay all or any portion of the principal of this Note without premium or penalty, except as set forth herein. Any prepayment made hereunder shall be made together with all interest accrued but unpaid on this Note through the date of such prepayment. If Borrower makes any prepayment of principal with respect to any LIBOR Balance on any day prior to the last day of the Interest Period applicable to such LIBOR Balance, Borrower shall reimburse the Lender on demand the Consequential Loss incurred by Lender as a result of the timing of such payment. A certificate of Lender setting forth the basis for the determination of a Consequential Loss shall be delivered to Borrower and shall, in the absence of manifest error, be prima facie evidence as to such determination and amount.

      Special Provisions for LIBOR Pricing. Borrower agrees to the following special provisions regarding LIBOR pricing:

          (a) If Lender determines that, by reason of circumstances affecting the London interbank offered rate market generally, deposits in Dollars (in the applicable amounts) are not being offered to United States financial institutions in the London interbank offered rate market for the applicable Interest Period, or that the rate at which such Dollar deposits are being offered will not adequately and fairly reflect the cost to Lender of making or maintaining a LIBOR Balance for the applicable Interest Period, Lender shall forthwith give written notice to Borrower, and thereafter until Lender notifies Borrower that the circumstances giving rise to such suspension no longer exist, (i) the right of Borrower to select the Adjusted LIBOR Rate as an Interest Option under this Note shall be suspended, and (ii) Borrower shall be deemed to have converted each LIBOR Balance to a Stated Rate Balance under this Note in accordance with the provisions hereof on the last day of the then-current Interest Period applicable to such LIBOR Balance.

          (b) If the adoption of any applicable law, rule, or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank, or agency charged with the interpretation or administration thereof, or compliance by Lender with any request or directive (whether or not having the force of law) of any such authority, central bank, or agency shall make it unlawful or impossible for Lender to make or maintain a LIBOR Balance, Lender shall so notify Borrower. Upon receipt of such written notice, Borrower shall be deemed to have converted any LIBOR Balance to a Stated Rate Balance under this Note, on either (i) the last day of the then-current Interest Period applicable to such LIBOR Balance if Lender may lawfully continue to maintain and fund such LIBOR Balance to such day, or (ii) immediately if Lender may not lawfully continue to maintain such LIBOR Balance to such day.

          (c) If any governmental authority, central bank, or other comparable authority, shall at any time after the date of this Note impose, modify, or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit, or similar requirement against assets of, deposits with or for the account of, or credit extended by, Lender, or shall impose on Lender (or its LIBOR lending office) or the London interbank offered rate market any other condition affecting its LIBOR Balance, this Note, or its obligation to make LIBOR advances; and the result of any of the foregoing is to increase the cost to Lender of making or maintaining its LIBOR Balance, or to reduce the amount of any sum received or receivable by Lender under this Note by an amount reasonably deemed by Lender to be material; then, within five (5) days after demand by Lender, Borrower shall pay to Lender, such additional amount or amounts as will compensate Lender for such increased cost or reduction. Lender will promptly notify Borrower of any event of which it has knowledge, occurring after the date hereof, which will entitle Lender to compensation pursuant to this Subsection. A certificate of Lender claiming compensation under this Subsection and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. If Lender demands compensation under this Subsection, then Borrower may at any time, upon at least five (5) Business Days prior notice to Lender, either (i) repay in full the then outstanding LIBOR Balance, together with accrued interest thereon to the date of prepayment, or (ii) convert such LIBOR Balance to Stated Rate Balance in accordance with the provisions of this Note; provided, however, that Borrower shall be liable for any Consequential Loss arising pursuant to such actions.

          (d) If (i) the obligation of Lender to permit LIBOR Balance has been suspended pursuant to subsections (a) or (b) above or (ii) Lender has demanded compensation under subsection (c) above, then, unless and until Lender notifies Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply, all advances on this Note which would otherwise be made by Lender as LIBOR Balance shall be made instead as Stated Rate Balance.

      Business Loan. Borrower represents to and covenants with Lender that: (1) all loans evidenced by this Note are and shall be “business loans” as that term is used in the Depository Institutions Deregulation and Monetary Control Act of 1980, as amended; and (2) the loans are for business, commercial, investment, or other similar purposes and not for personal, family, household, or agricultural use, as those terms are used in the Texas Finance Code.

      Event of Default. Borrower agrees that upon the occurrence of any one or more of the following events of default and the expiration of any notice, grace, or cure period provided for in the Loan Agreement (“ Event of Default ”):

     (a) failure of Borrower to pay any installment of principal of or interest on this Note or on any other indebtedness of Borrower to Lender when due; or

     (b) the occurrence of any Event of Default specified in the Loan Agreement;

the holder of this Note may, at its option, without further notice or demand, except such notice as is required by the Loan Agreement, (i) declare the outstanding principal balance of and accrued but unpaid interest on this Note at once due and payable, without presentment, demand for payment, notice of intent to accelerate, other notice of acceleration or dishonor, protest, or notice of protest of any kind, all of which are expressly waived by Borrower (ii) refuse to advance any additional amounts under this Note, (iii) foreclose all liens securing payment hereof, (iv) pursue any and all other rights, remedies, and recourses available to the holder hereof, including but not limited to any such rights, remedies, or recourses under the Loan Documents, at law or in equity, or (v) pursue any combination of the foregoing.

      No Waiver by Lender. The failure to exercise the option to accelerate the maturity of this Note or any other right, remedy, or recourse available to the holder hereof upon the occurrence of an Event of Default hereunder shall not constitute a waiver of the right of the holder of this Note to exercise the same at that time or at any subsequent time with respect to such Event of Default or any other Event of Default while such Event of Default is outstanding. The rights, remedies, and recourses of the holder hereof, as provided in this Note and in any other Loan Documents, shall be cumulative and concurrent and may be pursued separately, successively, or together as often as occasion therefor shall arise, at the sole discretion of the holder hereof. The acceptance by the holder hereof of any payment under this Note which is less than the payment in full of all amounts due and payable at the time of such payment shall not (i) constitute a waiver of or impair, reduce, release, or extinguish any right, remedy, or recourse of the holder hereof, or nullify any prior exercise of any such right, remedy, or recourse, or (ii) impair, reduce, release, or extinguish the

obligations of any party liable under any of the Loan Documents as originally provided herein or therein.

      Usury Savings Clause. This Note and all other Loan Documents are intended to be performed in accordance with, and only to the extent permitted by, all applicable usury laws. If any provision hereof or of any other Loan Documents or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision to any other person or circumstance nor the remainder of the instrument in which such provision is contained shall be affected thereby, and all provisions shall be enforced to the greatest extent permitted by law. It is expressly stipulated and agreed to be the intent of the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable on the indebtedness evidenced by this Note. If the applicable law is ever revised, repealed, or judicially interpreted so as to render usurious any amount called for under this Note or under any other Loan Documents, or contracted for, charged, taken, reserved, or received with respect to the indebtedness evidenced by this Note, or if Lender’s exercise of the option to accelerate the maturity of this Note or if any prepayment by Borrower results in Borrower having paid any interest in excess of that permitted by law, then it is the express intent of Borrower and Lender that all excess amounts theretofore collected by Lender be credited on the principal balance of this Note (or, if this Note and all other indebtedness arising under or pursuant to the other Loan Documents have been paid in full, refunded to Borrower), and the provisions of this Note and the other Loan Documents immediately be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the then-applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder or thereunder. All sums paid, or agreed to be paid, by Borrower for the use, forbearance, detention, taking, charging, receiving, or reserving of the indebtedness of Borrower to Lender under this Note or arising under or pursuant to the other Loan Documents shall, to the maximum extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the usury ceiling from time to time in effect and applicable to such indebtedness for so long as such indebtedness is outstanding. To the extent federal law permits Lender to contract for, charge, or receive a greater amount of interest, Lender will rely on federal law instead of Texas Finance Code, for the purpose of determining the Maximum Rate. Additionally, to the maximum extent permitted by applicable law now or hereafter in effect, Lender may, at its option and from time to time, implement any other method of computing the Maximum Rate under the Texas Finance Code, or under other applicable law by giving notice, if required, to Borrower as provided by applicable law now or hereafter in effect. Notwithstanding anything to the contrary contained herein or in any other Loan Documents, it is not the intention of Lender to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration.

      Applicability of Laws. In no event shall Chapter 346 of the Texas Finance Code (which regulates certain revolving loan accounts and revolving tri-party accounts) apply to this Note. To the extent that Chapter 303 of the Texas Finance Code is applicable to this Note, the “weekly ceiling” specified in Chapter 303 is the applicable ceiling; provided that, if any applicable law permits greater interest, the law permitting the greatest interest shall apply.

      Attorneys Fees. If this Note is placed in the hands of an attorney for collection, or is collected in whole or in part by suit or through bankruptcy, or other legal proceedings of any kind, Borrower agrees to pay, in addition to all other sums payable hereunder, all costs and expenses of collection, including but not limited to reasonable attorneys fees.

      Borrower’s Waiver. Except as expressly provided herein, Borrower and any and all endorsers and guarantors of this Note severally waive presentment for payment, notice of nonpayment, protest, demand, notice of protest, notice of intent to accelerate, notice of acceleration and dishonor, diligence in enforcement and indulgences of every kind and without further notice hereby agree to renewals, extensions, exchanges or releases of collateral, taking of additional collateral, indulgences, or partial payments, either before or after maturity.

      Applicable Law. EXCEPT TO THE EXTENT THAT THE LAWS OF THE UNITED STATES MAY APPLY, THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS. THIS INSTRUMENT IS MADE AND IS PERFORMABLE IN DALLAS, DALLAS COUNTY, TEXAS, AND IN THE EVENT OF A DISPUTE INVOLVING THIS NOTE OR ANY OTHER INSTRUMENT EXECUTED IN CONNECTION HEREWITH, BORROWER IRREVOCABLY AGREES THAT VENUE FOR SUCH DISPUTES SHALL BE IN ANY COURT OF COMPETENT JURISDICTION IN DALLAS COUNTY, TEXAS.
