WHEREAS, the Borrowers have requested that the Lenders increase the Acquisition Commitment to $15,000,000 and make certain other changes to the Loan Agreement, and the Lenders are willing to do so;

NOW, THEREFORE, in consideration of the premises herein contained and other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

1. Defined Terms. All capitalized terms used but not otherwise defined in this Amendment shall have the meaning ascribed to them in the Loan Agreement. Unless otherwise specified, all section references herein refer to sections of the Loan Agreement.

2. Amendments to Loan Agreement.

2.1 Definitions (Section 1).

(a) Acquisition Commitment. The definition of “Acquisition Commitment” is amended by substituting “$15,000,000” for “$5,000,000.”

(b) AEI. The following definition is added to the Loan Agreement:

“‘AEI’ means Ascent Energy Inc., a Delaware corporation.”

(c) Base Rate Margin. Clause (b) of the definition of “Base Rate Margin” is amended to read as follows:

“(b) For Acquisition Loans: two and one-half percent (2.50%) per annum.”

(d) Effective Date of First Amendment. The following definition is added to the Loan Agreement:

“‘Effective Date of First Amendment’ means the date on which the Borrowers have satisfied the conditions to the effectiveness of the First Amendment to Second Amended and Restated Loan Agreement dated as of May 1, 2006.”

(e) LIBOR Margin. Clause (b) of the definition of “LIBOR Margin” is amended to read as follows:

“(b) For Acquisition Loans: three and three-quarters percent (3.75%) per annum.”

2.2 Section 2(b) (Acquisition Commitment). Section 2(b) is amended to read as follows:

“(b) Acquisition Commitment. Subject to the terms and conditions hereof, each Lender agrees to make loans to the Borrowers in order to finance the acquisition of Oil and Gas Properties (or the equity of any Person owning Oil and Gas Properties) (herein called such Lender’s “Acquisition Loans”) upon the Borrowers’ request from time to time during the term hereof, provided that (i) all Lenders are requested to make Acquisition Loans of the same Type in accordance with their respective Percentage Shares and as part of the same Advance, and (ii) the aggregate amount of all Acquisition Loans may not exceed seventy percent (70%) of the net discounted present value, determined by the Agent using the factors set forth in Section 9(f) hereof, of the proved Oil and Gas Properties being acquired with the proceeds of such Acquisition Loans (the “70% Test”). In determining whether the Borrowers have satisfied

2

the 70% Test: (i) if the acquisition being financed is for a consideration of $10,000,000 or more, the net discounted present value of the Oil and Gas Properties being acquired will be determined on the basis of an engineering report in form and substance satisfactory to the Agent in its reasonable discretion prepared by a representative of the Borrowers but audited by an independent third party engineer selected by the Borrowers and approved by the Agent covering the Oil and Gas Properties being acquired, and (ii) if the acquisition being financed is for a consideration of less than $10,000,000, the net discounted present value of the Oil and Gas Properties being acquired will be determined on the basis of an engineering report in form and substance satisfactory to the Agent in its reasonable discretion prepared by a representative of the Borrowers covering the Oil and Gas Properties being acquired. In either case, net discounted present value will be calculated using a predetermined price deck provided to the Borrowers by the Agent and acceptable to the Lenders. The aggregate amount of all Acquisition Loans in any Advance must be greater than or equal to $1,000,000. Except for the amount of any Acquisition Loan which may have been converted to a term loan pursuant to Section 4(a)(ii) hereof, subject to the terms and conditions hereof, the Borrowers may borrow, repay, and reborrow Acquisition Loans made hereunder. The Lenders shall have no obligation to make an Acquisition Loan hereunder if such Acquisition Loans would not satisfy the 70% Test.”

2.3 Section 4(a) (Payment at Maturity). Section 4(a)(ii) is amended to read as follows:

“(ii) Except as otherwise provided in this Agreement, the outstanding principal amount of the Acquisition Loans shall be due and payable on the later of (y) a date which is six months after the date of the Advance of such Acquisition Loan, or (z) a date which is three months after the date of the first Borrowing Base Determination Date following the Advance of such Acquisition Loan (the “Acquisition Loan Maturity Date”), provided, however, that if on the Acquisition Loan Maturity Date the Facility Usage plus the outstanding principal amount of Acquisition Loans exceeds the Borrowing Base in effect on such Acquisition Loan Maturity Date, then the amount of such excess (other than any excess attributable to a Borrowing Base Deficiency, which shall be addressed as otherwise provided in this Agreement) shall be converted into a term loan which shall be payable in not more than thirty-six (36) equal installments due on the last Business Day of each month prior to the Loan Maturity Date and, if not then paid in full, on the Loan Maturity Date. As an example for the avoidance of doubt, if the amount of such excess (other than any excess attributable to a Borrowing Base Deficiency) on an Acquisition Loan Maturity Date which is January 15, 2009 is $1,650,000, then the Borrower must make eleven (11) equal payments of $150,000 each, with ten (10) such payments being made on the last Business Day of

3

each month commencing on the last Business Day of January, 2009, and the eleventh (11^th) such payment being made on November 1, 2009, the Loan Maturity Date.“

2.4 Annex A. Annex A to the Loan Agreement is deleted and replaced by Annex A attached to this Amendment.

3. Borrowing Base. Pursuant to Section 9 of the Loan Agreement, the Agent and the Lenders have redetermined the Borrowing Base at $80,000,000, which Borrowing Base shall be effective on the Effective Date of the First Amendment. The redetermination provided for in this Section 4 shall not be treated as an Unscheduled Redetermination for purposes of the Loan Agreement.

4. Effectiveness of Amendment. This Amendment shall be effective upon receipt by the Agent of:

4.1 An executed copy of this Amendment;

4.2 A promissory note executed by the Borrowers in favor of each Lender; and

10. Entire Agreement. The Loan Agreement, as amended by this Amendment, contains the entire agreement among the parties regarding the subject matter hereof and supersedes all prior written and oral agreements and understandings among the parties hereto regarding same.

11. Reference to Loan Agreement. The Loan Agreement and any and all other agreements, documents or instruments now or hereafter executed and delivered pursuant to the terms hereof or pursuant to the terms of the Loan Agreement, as amended hereby, are hereby amended so that any reference in the Loan Agreement to the Loan Agreement shall mean a reference to the Loan Agreement as amended hereby.

12. Counterparts. This Amendment may be separately executed in any number of counterparts, each of which shall be an original, but all of which, taken together, shall be deemed to constitute one and the same agreement.
