THIRD AMENDED AND RESTATED CREDIT AGREEMENT

     This Third Amended and Restated Credit Agreement dated as of December 29, 2010, is among Delta Petroleum Corporation, a Delaware corporation (“Borrower”), the lenders party hereto from time to time (the “Lenders”), and Macquarie Bank Limited, as administrative agent for such Lenders (in such capacity, the “Administrative Agent”) and as issuing lender for such Lenders (in such capacity, the “Issuing Lender”).

Background

     A. On November 3, 2008, Borrower entered into the JPMorgan Credit Facility (as defined below).

     B. Immediately prior to the execution of this Agreement, JPMorgan Chase Bank, N.A. assigned all of its rights and obligations under the JPMorgan Credit Facility and the other Loan Papers (as defined in the JPMorgan Credit Facility) to Administrative Agent for the benefit of Lenders pursuant to an Assignment of Liens and Security Interests dated December 29, 2010.

     C. Immediately prior to the execution of this Agreement, each lender under the JPMorgan Credit Facility assigned all of its rights and obligations under the JPMorgan Credit Facility and the other transferred Loan Papers (as defined in the JPMorgan Credit Facility) to Lenders pursuant to an Assignment and Acceptance dated December 29, 2010.

     D. Borrower, Administrative Agent and each Lender agree to amend and restate the terms of the JPMorgan Credit Facility as set forth in this Agreement.

     E. Borrower, Administrative Agent and each of the Lenders agree that this Agreement sets forth the terms and conditions pursuant to which Lenders will make available to Borrower a senior secured loan for the purposes set forth in this Agreement.

     F. In connection with Lenders making available to Borrower the financial accommodations described in this Agreement, Borrower will grant to Administrative Agent, for the ratable benefit of each of Lenders, a first-priority Lien in all of the real and personal property of Borrower subject only to the Permitted Liens (defined below).

Agreements

     For good and valuable consideration, the receipt and sufficiency of which are acknowledged by each of the parties, Borrower, Lenders, Administrative Agent and Issuing Lender hereby agree as follows:

ARTICLE I
DEFINITIONS AND ACCOUNTING TERMS

     Section 1.1. Certain Defined Terms. As used in this Agreement, the terms defined above shall have the meanings set forth therein and the following terms shall have the meanings set forth on Appendix I (unless otherwise indicated, such meanings to be equally applicable to both the singular and plural forms of the terms defined).

     Section 1.2. Computation of Time Periods. In this Agreement, with respect to the computation of periods of time from a specified date to a later specified date, the word “from” means “from and including” and the words “to” and “until” each means “to but excluding”.

     Section 1.3. Accounting Terms; Changes in GAAP. Except as otherwise expressly provided herein, all accounting terms used herein shall be interpreted, and all financial statements and certificates and reports as to financial matters required to be delivered to the Lenders hereunder shall (unless otherwise disclosed to the Lenders in writing at the time of delivery thereof) be prepared, in accordance with GAAP applied on a basis consistent with those used in the preparation of the latest financial statements furnished to the Lenders hereunder (which prior to the delivery of the first financial statements under Section 5.6, shall mean the Financial Statements and the Interim Financial Statements). All calculations made for the purposes of determining compliance with this Agreement shall (except as otherwise expressly provided herein) be made by application of GAAP applied on a basis consistent with those used in the preparation of the annual or quarterly financial statements furnished to the Lenders pursuant to Section 5.6 most recently delivered prior to or concurrently with such calculations (or, prior to the delivery of the first financial statements under Section 5.6, used in the preparation of the Financial Statements and the Interim Financial Statements). If at any time any change in GAAP would affect the computation of any financial ratio or requirement set forth herein, and either Borrower or the Required Lenders shall so request, Administrative Agent, the Lenders and Borrower shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Required Lenders); provided that, until so amended, (a) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein, and (b) Borrower shall provide to Administrative Agent and the Lenders financial statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP.

     Section 1.4. Types of Advances. Advances are distinguished by “Type.” The “Type” of an Advance refers to the determination whether such Advance is a Eurodollar Rate Advance or Reference Rate Advance.

     Section 1.5. Miscellaneous. Article, Section, Schedule, and Exhibit references are to Articles and Sections of and Schedules and Exhibits to this Agreement, unless otherwise specified. All references to instruments, documents, contracts, and agreements are references to such instruments, documents, contracts, and agreements as the same may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified. The words “hereof”, “herein”, and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “including” means “including, without limitation,”. Paragraph headings have been inserted in this Agreement as a matter of convenience for reference only and it is agreed that such paragraph headings are not a part of this Agreement and shall not be used in the interpretation of any provision of this Agreement.

ARTICLE II
CREDIT FACILITIES

     Section 2.1. Maximum Commitment.

     (a) Maximum Commitment. Each Lender severally agrees, subject to the terms and conditions of this Agreement, prior to the applicable Commitment Termination Date to make available to Borrower (i) a senior secured revolving loan pursuant to the terms and conditions of Section 2.2 (the “Revolving Loan”) and (ii) a senior secured term loan pursuant to the terms and conditions of Section 2.3 (the “Term Loan”) not to exceed in aggregate such Lender’s Commitment for the purposes set forth herein and not to exceed the Maximum Commitment. Borrower acknowledges that Lenders do not intend to advance Borrower any amount which would at any point in time exceed the Maximum Commitment; provided, however, if the obligations of Borrower under the Revolving Loan and the Term Loan exceed the Maximum Commitment, all obligations will nevertheless constitute Obligations under this Agreement and be entitled to the benefit of all of Administrative Agent’s Liens on the Collateral. All monetary Obligations (other than Obligations that may continue past the Maturity Date under the terms of a Hedge Contract with a Hedge Counterparty) will be fully due and payable on the Maturity Date.

     (b) Advances. Each Borrowing shall, in the case of Borrowings consisting of Reference Rate Advances, be in an aggregate amount not less than $250,000 and in integral multiples of $100,000 in excess thereof, and in the case of Borrowings consisting of Eurodollar Rate Advances, be in an aggregate amount not less than $500,000 and in integral multiples of $100,000 in excess thereof, and in each case shall consist of Advances of the same Type made on the same day by the Lenders ratably according to their respective Commitments. Within the limits of each Lender’s Commitment, and subject to the terms of this Agreement, Borrower may from time to time borrow, prepay, and reborrow Advances under the Revolving Loan. Amounts repaid in respect of the Term Loan may not be reborrowed.

     (c) Notes. The indebtedness of Borrower to each Lender resulting from the Advances owing to such Lender shall be evidenced by a Note of Borrower payable to the order of such Lender.

     Section 2.2. Availability and Purpose of Revolving Loan Advances.

     (a) Revolving Loan. The initial Borrowing Base available under the Revolving Loan in effect as of Effective Date has been set by Administrative Agent and the Lenders and acknowledged by Borrower as $30,000,000. Such initial Borrowing Base shall remain in effect until the next redetermination made pursuant to this Section 2.2. The Borrowing Base shall be determined in accordance with the standards set forth in Section 2.2(d) and is subject to periodic redetermination pursuant to Section 2.2(b), Section 2.2(c) and Section 2.2(e). Advances under the Borrowing Base shall be used in accordance with Section 5.9. Up to $5,000,000 of the Borrowing Base may be used for the issuance of Letters of Credit pursuant to Section 2.10.

     (b) Calculation of Borrowing Base.

          (i) Borrower shall deliver to Administrative Agent and each of the Lenders on or before each April 1, beginning April 1, 2011, an Independent Engineering Report dated effective as of the immediately preceding January 1, and such other information as may be

reasonably requested by any Lender, including but not limited to the Oil and Gas Properties included or to be included in the Borrowing Base. After Administrative Agent and the Lenders’ receipt of such Independent Engineering Report and other information, (A) Administrative Agent shall deliver to each Lender Administrative Agent’s recommendation for the redetermined Borrowing Base, (B) Administrative Agent and the Lenders shall redetermine the Borrowing Base in accordance with Section 2.2(d), and (C) Administrative Agent shall promptly notify Borrower in writing of the amount of the Borrowing Base as so redetermined.

          (ii) Borrower shall deliver to Administrative Agent and each Lender, on or before each October 1, beginning October 1, 2011, an Internal Engineering Report dated effective as of the immediately preceding July 1st and such other information as may be reasonably requested by Administrative Agent or any Lender including but not limited to the Oil and Gas Properties included or to be included in the Borrowing Base. After Administrative Agent and the Lenders’ receipt of such Internal Engineering Report and other information, (A) Administrative Agent shall deliver to each Lender Administrative Agent’s recommendation for the redetermined Borrowing Base, (B) Administrative Agent and the Lenders shall redetermine the Borrowing Base in accordance with Section 2.2(d), and (C) Administrative Agent shall promptly notify Borrower in writing of the amount of the Borrowing Base as so redetermined.

          (iii) In the event that Borrower does not furnish to Administrative Agent and the Lenders the Independent Engineering Report, Internal Engineering Report or other information specified in clauses (i) and (ii) above by the date specified therein, Administrative Agent and the Lenders may nonetheless redetermine the Borrowing Base and redesignate the Borrowing Base from time-to-time thereafter in their sole discretion until Administrative Agent and the Lenders receive the relevant Independent Engineering Report, Internal Engineering Report, or other information, as applicable, whereupon Administrative Agent and the Lenders shall redetermine the Borrowing Base as otherwise specified in this Section 2.2.

          (iv) Each delivery of an Engineering Report by Borrower to Administrative Agent and the Lenders shall constitute a representation and warranty by Borrower to Administrative Agent and the Lenders that:

          (A) Borrower owns the Oil and Gas Properties specified therein with at least 90% (by value) of the Proved Reserves covered therein subject to an Acceptable Security Interest and free and clear of any Liens (except Permitted Liens),

          (B) on and as of the date of such Engineering Report each Oil and Gas Property described as “proved developed” therein was developed for oil or gas, and the wells pertaining to such Oil and Gas Properties that are described therein as producing Wells, were each capable of producing oil and/or gas in paying quantities, except for Wells that were utilized as water or gas injection wells, carbon dioxide wells or as water disposal wells (each as noted in such Engineering Report),

          (C) the descriptions of quantum and nature of the record title interests of Borrower, as applicable, set forth in such Engineering Report include the entire record title interests of Borrower in such Oil and Gas Properties, are complete and accurate in all respects, and take into account all Permitted Liens,

          (D) there are no “back-in” or “reversionary” interests held by third parties which could reduce the interests of Borrower in such Oil and Gas Properties except as set forth in such Engineering Report,

          (E) no operating or other agreement to which Borrower is a party or by which Borrower is bound affecting any part of such Oil and Gas Properties requires Borrower to bear any of the costs relating to such Oil and Gas Properties greater than the record title interest of Borrower in such portion of the such Oil and Gas Properties as set forth in such Engineering Report, except in the event Borrower is obligated under an operating agreement to assume a portion of a defaulting party’s share of costs, and

          (F) Borrower’s ownership of the Hydrocarbons and the undivided interests in the Oil and Gas Properties as specified in such Engineering Report (i) will, after giving full effect to all Permitted Liens, afford Borrower not less than those net interests (expressed as a fraction, percentage or decimal) in the production from or which is allocated to such Hydrocarbons specified as Net Revenue Interest in such Engineering Report and (ii) will cause Borrower to bear not more than that portion (expressed as a fraction, percentage or decimal), specified as Working Interest in such Engineering Report, of the costs of drilling, developing and operating the wells identified in such Engineering Report or identified in the exhibits to the Mortgages encumbering such Oil and Gas Properties (except for any increases in Working Interest with a corresponding increase in the Net Revenue Interest in such Oil and Gas Property).

     (c) Interim Redetermination. In addition to the Borrowing Base redeterminations provided for in Section 2.2(b), (i) based on such information as Administrative Agent and the Lenders deem relevant (but in accordance with Section 2.2(d)), Administrative Agent may, and shall at the request of the Required Lenders, require one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations; (ii) based on such information as Administrative Agent and the Lenders deem relevant (but in accordance with Section 2.2(d)), Borrower may require one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations; and (iii) Administrative Agent and the Lenders may make additional redeterminations of the Borrowing Base in connection with any Disposition of Oil and Gas Properties constituting Proved Reserves of Borrower having a fair market value which, when taken together with (A) the fair market value of all other Dispositions of Oil and Gas Properties constituting Proved Reserves of Borrower and (B) the Net Hedge Value for such BB Hedges that have been subject to novations, assignments, unwinding, amendments, or terminations, in each case, occurring since the date of the most recent scheduled Borrowing Base redetermination, equals or exceeds 5% of the Borrowing Base then in effect. For the avoidance of doubt, such additional redeterminations of the Borrowing Base shall not constitute nor be construed as a consent to any transaction or proposed transaction that would not be permitted under the terms of this Agreement. In connection with any redetermination of the Borrowing Base under this Section 2.2(c), Borrower shall provide Administrative Agent and the Lenders with such information regarding Borrower’s business (including, without limitation, its Oil and Gas Properties, the Proved Reserves, and production relating thereto) as Administrative Agent or any Lender may reasonably request. Administrative Agent shall promptly notify Borrower in writing of each redetermination of the Borrowing Base pursuant to this Section 2.2(c) and the amount of the Borrowing Base as so redetermined.

     (d) Standards for Redetermination. Each redetermination of the Borrowing Base by Administrative Agent and the Lenders pursuant to this Section 2.2 shall be made (i) in the sole discretion of Administrative Agent and the Lenders (but in accordance with the other provisions of this Section 2.2(d)), (ii) in accordance with Administrative Agent’s and the Lenders’ customary internal standards and practices for valuing and redetermining the value of Oil and Gas Properties in connection with reserve based oil and gas loan transactions, (iii) in conjunction with the most recent Independent Engineering Report or Internal Engineering Report, as applicable, or other information received by Administrative Agent and the Lenders including but not limited to the Proved Reserves of Borrower, and (iv) based upon the estimated value of the Proved Reserves owned by Borrower as determined by Administrative Agent and the Lenders. In valuing and redetermining the Borrowing Base, Administrative Agent and the Lenders may also consider the business, financial condition, and Debt obligations of Borrower and the Guarantors and such other factors as Administrative Agent and the Lenders customarily deem appropriate, including without limitation, commodity price assumptions, projections of production, operating expenses, general and administrative expenses, capital costs, working capital requirements, liquidity evaluations, dividend payments, environmental costs, and legal costs. In that regard, Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is essential for the adequate protection of Administrative Agent and the Lenders. No Proved Reserves shall be included or considered for inclusion in the Borrowing Base unless Administrative Agent shall have received, at Borrower’s expense, (A) evidence of title reasonably satisfactory in form and substance to Administrative Agent covering at least 90% (by value) of the Proved Reserves and the Oil and Gas Properties relating thereto and (B) Mortgages and such other Security Instruments requested by Administrative Agent to the extent necessary to cause Administrative Agent to have an Acceptable Security Interest in at least 90% (by value) of the Proved Reserves and the Oil and Gas Properties relating thereto. At all times after Administrative Agent has given Borrower notification of a redetermination of the Borrowing Base under this Section 2.2, the Borrowing Base shall be equal to the redetermined amount or such lesser amount designated by Borrower and disclosed in writing to Administrative Agent and the Lenders until the Borrowing Base is subsequently redetermined in accordance with this Section 2.2; provided that Borrower shall not request that the Borrowing Base be reduced to a level that would result in a Borrowing Base deficiency. Notwithstanding anything herein to the contrary, (x) other than for the mandatory reduction provided in Section 2.2(e) to the extent the redetermined Borrowing Base is less than or equal to the Borrowing Base in effect prior to such redetermination, such redetermined Borrowing Base must be Approved by Administrative Agent and the Required Lenders, and (y) to the extent the redetermined Borrowing Base is greater than the Borrowing Base in effect prior to such redetermination, such redetermined Borrowing Base must be Approved by Administrative Agent and all of the Lenders.

     (e) Mandatory Reductions in the Borrowing Base. In addition to the Borrowing Base redeterminations provided for otherwise in this Section 2.2, if Borrower or any Guarantor novates, assigns, unwinds, terminates, or amends any BB Hedge, then the Borrowing Base shall automatically reduce by an amount equal to the negative Net Hedge Value, if any, resulting from such event. Such mandatory reduction of the Borrowing Base shall be effective as of the date Administrative Agent notifies Borrower of the negative Net Hedge Value resulting from such event.

     Section 2.3. Availability and Purposes of Term Loan Advances. Beginning on the Closing Date, and subject to the Approval by Administrative Agent and Required Lenders of the initial Development Plan, and any subsequent modifications of the Development Plan pursuant to Section 2.4(a), and continuing through the applicable Commitment Termination Date, up to $20,000,000 is available under the Term Loan and shall be used by Borrower in accordance with Section 5.9 and as follows:

     (a) to pay costs incurred by Borrower in connection with the drilling and completion of Wells and other development activities included on the Development Plan, in each instance, pursuant to an AFE Approved by Administrative Agent; and

     (b) for any other purpose Approved by Administrative Agent.

     Section 2.4. Development Plan.

     (a) The initial Development Plan is attached as Schedule 2.4. Administrative Agent Approves the initial Development Plan. Borrower may propose modifications to the Development Plan from time to time, and those modifications will become effective when Approved by Administrative Agent and the Required Lenders. Approval of any Development Plan is within the sole and absolute discretion of Administrative Agent and the Required Lenders and Administrative Agent and the Required Lenders may make their Approval subject to such conditions as Administrative Agent and the Required Lenders deem appropriate.

     (b) In support of each Development Plan, Borrower will prepare and submit to Administrative Agent for Approval an AFE (including all Supporting Documentation) at least fifteen days before Borrower incurs any costs that it intends to fund out of an Advance under the Term Loan. To the extent an AFE conforms to a Development Plan previously Approved by Administrative Agent and Required Lenders, however, Administrative Agent’s Approval of that AFE will not be unreasonably withheld or delayed.

     (c) Notwithstanding the foregoing Approval of a Development Plan:

          (i) Borrower must nevertheless satisfy the conditions described in this Article II and Article III below prior to the making of each Advance; and

          (ii) Administrative Agent will have no obligation to make an Advance to fund projects included on the Development Plan:

          (A) unless the requested Advance relates to an AFE Approved by Administrative Agent;

          (B) if the requested Advance (together with all amounts previously Advanced in respect of the applicable AFE) exceeds the cost set forth in the Development Plan for that project by more than 10%; or

          (C) if the requested Advance exceeds the remaining funds available and not yet Advanced under the Term Loan.

     Section 2.5. Method of Borrowing.

     (a) Notice. Each Borrowing shall be made pursuant to a Notice of Borrowing (or by telephone notice promptly confirmed in writing by a Notice of Borrowing), given not later than 11:00 a.m. (Houston, Texas time) (i) on the third Business Day before the date of the proposed Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances or (ii) one Business Day prior to the proposed Borrowing, in the case of a Borrowing comprised of Reference Rate Advances, by Borrower to Administrative Agent, which shall in turn give to each Lender prompt notice of such proposed Borrowing by facsimile. Each Notice of a Borrowing shall be given by facsimile, confirmed immediately in writing, specifying the information required therein. In the case of a proposed Borrowing comprised of Eurodollar Rate Advances, Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.14(b). Each Lender shall, before 1:00 pm (Houston, Texas time) on the date of such Borrowing, make available for the account of its Lending Office to Administrative Agent at its address referred to in Section 9.2, or such other location as Administrative Agent may specify by notice to the Lenders, in same day funds, in the case of a Borrowing, such Lender’s Pro Rata Share of such Borrowing. After Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, Administrative Agent shall make such funds available to Borrower at its account with Administrative Agent.

     (b) Conversions and Continuations. Borrower may elect to Convert or continue any Borrowing under this Section 2.5 by delivering an irrevocable Notice of Conversion or Continuation to Administrative Agent at Administrative Agent’s office no later than 11:00 a.m. (Houston, Texas time) (i) on the date which is at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to or a continuation of a Borrowing comprised of Eurodollar Rate Advances and (ii) one Business Day prior to the proposed Conversion in the case of a Conversion to a Borrowing comprised of Reference Rate Advances. Each such Notice of Conversion or Continuation shall be in writing or by facsimile confirmed immediately in writing specifying the information required therein. Promptly after receipt of a Notice of Conversion or Continuation under this Section 2.5, Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a continuation of a Borrowing comprised of Eurodollar Rate Advances, notify each Lender of the applicable interest rate under Section 2.14(b).

     (c) Certain Limitations. Notwithstanding anything to the contrary contained in paragraphs (a) and (b) above:

          (i) at no time shall there be more than six Interest Periods applicable to outstanding Eurodollar Rate Advances and Borrower may not select Eurodollar Rate Advances for any Borrowing at any time that a Default has occurred and is continuing;

          (ii) if any Lender shall, at least one Business Day before the date of any requested Borrowing, Conversion, or continuation, notify Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances, the right of

Borrower to select Eurodollar Rate Advances from such Lender shall be suspended until such Lender shall notify Administrative Agent that the circumstances causing such suspension no longer exist, and the Advance made by such Lender in respect of such Borrowing, Conversion, or continuation shall be a Reference Rate Advance;

          (iii) if Administrative Agent is unable to determine the Eurodollar Rate for Eurodollar Rate Advances comprising any requested Borrowing, the right of Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until Administrative Agent shall notify Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Reference Rate Advance;

          (iv) if the Required Lenders shall, at least one Business Day before the date of any requested Borrowing, notify Administrative Agent that the Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Rate Advances, as the case may be, for such Borrowing, the right of Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until Administrative Agent shall notify Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Reference Rate Advance; and

          (v) if Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Appendix I, Administrative Agent shall forthwith so notify Borrower and the Lenders and such Advances shall be made available to Borrower on the date of such Borrowing as Reference Rate Advances or, if an existing Advance, Convert into Reference Rate Advances.

     (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on Borrower. In the case of any Borrowing for which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, Borrower shall indemnify each Lender against any loss, out-of-pocket cost, or expense incurred by such Lender as a result of any failure by Borrower to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III including, without limitation, any loss (including any loss of anticipated profits), cost, or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

     (e) Administrative Agent Reliance. Unless Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender shall not make available to Administrative Agent such Lender’s Pro Rata Share of a Borrowing, Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to Administrative Agent on the date of such Borrowing in accordance with Section 2.5(a) and Administrative Agent may, in reliance upon such assumption, make available to Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to Administrative Agent, such Lender and

Borrower severally agree to immediately repay to Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to Borrower until the date such amount is repaid to Administrative Agent, at (i) in the case of Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for such day. If such Lender shall repay to Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

     (f) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

     Section 2.6. Reduction of the Commitments.

     (a) Borrower shall have the right, upon at least three Business Days’ irrevocable notice to Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitments; provided that each partial reduction shall be in the aggregate amount of at least $500,000 or in integral multiples of $100,000 in excess thereof.

     (b) Other than as provided in Section 2.6(c), any reduction and termination of the Commitments pursuant to this Section 2.6 shall be applied ratably to each Lender’s Commitment and shall be permanent, with no obligation of the Lenders to reinstate such Commitments.

     (c) In the event of a Defaulting Lender, Borrower, at Borrower’s election may elect to terminate such Defaulting Lender’s Commitment hereunder; provided that (i) such termination must be of the Defaulting Lender’s entire Commitment, (ii) Borrower shall pay all amounts owed by Borrower to such Defaulting Lender under this Agreement and under the other Loan Documents (including principal of and interest on the Advances owed to such Defaulting Lender, accrued commitment fees, and letter of credit fees but specifically excluding any amounts owing under Section 2.17 as result of such payment of Advances) and shall deposit with Administrative Agent into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender’s ratable share of the Letter of Credit Exposure, and (iii) unless otherwise consented to by Administrative Agent, a Defaulting Lender’s Commitment may be terminated by Borrower under this Section 2.6(c) if and only if at such time, Borrower has elected, or is then electing, to terminate the Commitments of all then existing Defaulting Lenders. Upon written notice to the Defaulting Lender and Administrative Agent of Borrower’s election to terminate a Defaulting Lender’s Commitment pursuant to this Section 2.6(c) and the payment and deposit of amounts required to be made by Borrower under clause (c), (A) such Defaulting Lender shall cease to be a “Lender” hereunder for all purposes except that such Lender’s rights under Sections 2.18, 2.19 and 9.7 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender” hereunder, (B) such Defaulting Lender’s Commitment shall be deemed terminated, and (C) such Defaulting Lender shall be relieved of its obligations hereunder other than its obligations under Section 8.5 with respect to events and occurrences occurring

before or concurrently with its ceasing to be a “Lender” hereunder; provided that, any such termination will not be deemed to be a waiver or release of any claim by Borrower, Administrative Agent or any Lender may have against such Defaulting Lender.

     Section 2.7. Prepayment of Advances.

     (a) Optional. Borrower may prepay the Advances, after giving by 11:00 a.m. (Houston, Texas time) (i) in the case of Eurodollar Rate Advances, at least three Business Days’ or (ii) in the case of Reference Rate Advances, same Business Day’s, irrevocable prior written notice to Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, Borrower shall prepay the Advances in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.17 as a result of such prepayment being made on such date; provided, however, that each partial prepayment with respect to: (A) any amounts prepaid in respect of Eurodollar Rate Advances shall be applied to Eurodollar Rate Advances comprising part of the same Borrowing; (B) any prepayments made in respect of Reference Rate Advances shall be made in a minimum amounts of $250,000 and in integral multiples of $100,000 in excess thereof, and (C) any prepayments made in respect of any Borrowing comprised of Eurodollar Rate Advances shall be made in an aggregate principal amount of at least $500,000 and in integral multiples of $100,000 in excess thereof, and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a remaining principal amount outstanding with respect to such Borrowing of at least $500,000. Full prepayments of any Borrowing are permitted without restriction of amounts.

     (b) Borrowing Base Deficiency.

          (i) Other than as provided in Section 2.7(b)(ii) below, if the aggregate outstanding amount of the Revolving Loan Advances plus the Letter of Credit Exposure ever exceeds the lesser of (y) the Borrowing Base and (z) the aggregate Commitments, Borrower shall, after receipt of written notice from Administrative Agent regarding such deficiency, take any of the following actions (and the failure of Borrower to take such actions to remedy such Borrowing Base deficiency shall constitute an Event of Default):

          (A) prepay Revolving Loan Advances or, if the Revolving Loan Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure, such that the Borrowing Base deficiency is cured within 30 days after the date such deficiency notice is received by Borrower from Administrative Agent;

          (B) pledge as Collateral for the Obligations additional Oil and Gas Properties acceptable to Administrative Agent and the Required Lenders such that the Borrowing Base deficiency is cured within 30 days after the date such deficiency notice is received by Borrower from Administrative Agent;

          (C) (1) deliver, within 10 days after the date such deficiency notice is received by Borrower from Administrative Agent, written notice to Administrative Agent

indicating Borrower’s election to repay the Revolving Loan Advances and make deposits into the Cash Collateral Account to provide cash collateral for the Letters of Credit, each in five monthly installments equal to one-fifth of such Borrowing Base deficiency with the first such installment due 30 days after the date such deficiency notice is received by Borrower from Administrative Agent and each following installment due 30 days after the preceding installment and (2) make such payments and deposits within such time periods; or

          (D) eliminate the Borrowing Base deficiency through a combination of the actions described in Sections 2.7(b)(i)(A), (B), and (C) above.

          (ii) Upon each reduction of the Borrowing Base, if any, resulting from a Borrowing Base redetermination made under Section 2.2(e) if the aggregate outstanding amount of the Revolving Loan Advances plus the Letter of Credit Exposure exceeds the lesser of (y) the Borrowing Base and (z) the aggregate Commitments, then Borrower shall immediately prepay the Revolving Loan Advances or, if the Revolving Loan Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure, in an amount equal to (A) such portion of the Borrowing Base deficiency resulting from such reduction plus (B) if a Borrowing Base deficiency exists prior to such reduction, then an amount equal to the lesser of (i) the net cash proceeds of the transaction that triggered such Borrowing Base reduction and (ii) such portion of the Borrowing Base deficiency in existence immediately prior to such reduction.

          (iii) Each prepayment pursuant to this Section 2.7(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.17 as a result of such prepayment being made on such date. Each prepayment under this Section 2.7(b) shall be applied to the Revolving Loan Advances as determined by Administrative Agent and agreed to by the Lenders in their sole discretion.

     (c) Reduction of Commitments. On the date of each reduction of the aggregate Commitments pursuant to Section 2.6, Borrower agrees to make a prepayment in respect of the outstanding amount of the Revolving Loan Advances to the extent, if any, that the aggregate unpaid principal amount of all Revolving Loan Advances plus the Letter of Credit Exposure exceeds the lesser of (i) the aggregate Commitments, as so reduced and (ii) the Borrowing Base. Each prepayment pursuant to this Section 2.7(c) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.17 as a result of such prepayment being made on such date. Each prepayment under this Section 2.7(c) shall be applied to the Revolving Loan Advances as determined by Administrative Agent and agreed to by the Lenders in their sole discretion.

     (d) Illegality. If any Lender shall notify Administrative Agent and Borrower that the introduction of or any change in or in the interpretation of any applicable Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its Lending Office to perform its obligations under this Agreement to maintain any Eurodollar Rate Advances of such Lender then outstanding hereunder, (i) Borrower shall, no later than 11:00 a.m. (Houston, Texas time) (A) if not prohibited by law, on

the last day of the Interest Period for each outstanding Eurodollar Rate Advance made by such Lender or (B) if required by such notice, on the second Business Day following its receipt of such notice, automatically convert to Reference Rate Advances all of the Eurodollar Rate Advances made by such Lender then outstanding, together with accrued interest on the principal amount converted to the date of such conversion and amounts, if any, required to be paid pursuant to Section 2.17 as a result of such conversion being made on such date, (ii) such Lender shall simultaneously make a Reference Rate Advance to Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Lender, and (iii) the right of Borrower to select Eurodollar Rate Advances from such Lender for any subsequent Borrowing shall be suspended until such Lender gives notice referred to above shall notify Administrative Agent that the circumstances causing such suspension no longer exist.

     (e) Optional Prepayment; Ratable Prepayment. Borrower may prepay the Revolving Loan and the Term Loan in whole or in part at any time without penalty or premium, except for breakage costs as set forth in Section 2.17 resulting from such prepayment. Except as provided in the preceding sentence, each payment of any Advance pursuant to this Section 2.7 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

     Section 2.8. Repayment of the Term Loan; Net Operating Cash Flow.

     (a) Repayment of Term Loan Generally. On each Payment Date beginning January 25, 2011, to the extent any Advances under the Term Loan remain outstanding, Borrower will pay to Administrative Agent 100% of Net Operating Cash Flow to be applied as set forth in Section 2.8(c). On the Maturity Date, Borrower will pay to Administrative Agent all of the monetary Obligations outstanding on that date (other than Obligations that may continue past the Maturity Date under the terms of any Hedge Contracts) and perform or otherwise satisfy all other Obligations then outstanding.

     (b) Calculation of Net Operating Cash Flow. Administrative Agent will calculate Net Operating Cash Flow based on the Property Operating Statements prepared and delivered by Borrower. The first Property Operating Statement is due on the twenty-fifth (25^th) day of the month following the month in which the first Advance under the Term Loan is made.

     (c) Application of Funds.

          (i) Payments due under Section 2.8(a) will be applied first to unpaid fees and Related Costs payable under the Loan Documents, second to accrued interest on the Loans, and third to principal on the Term Loan.

          (ii) Any prepayments made pursuant to the terms of this Agreement, will be applied first to unpaid fees and Related Costs payable under the Loan Documents, second to accrued interest on the Term Loan, third to principal on the Term Loan, and fourth to any principal on the Revolving Loan, and fifth to accrued interest on the Revolving Loan.

     Section 2.9. Repayment of Revolving Loan. Borrower shall repay to Administrative Agent for the ratable benefit of Lenders the outstanding principal amount of each Revolving

Loan Advance, together with any accrued interest thereon, on the Maturity Date or such earlier date pursuant to Section 7.2 or Section 7.3.

     Section 2.10. Letters of Credit.

     (a) Commitment. From time to time from the date of this Agreement until 30 days prior to the Maturity Date, at the request of Borrower, the Issuing Lender shall, on the terms and conditions hereinafter set forth, issue, increase, or extend the Expiration Date of, Letters of Credit for the account of Borrower on any Business Day. No Letter of Credit will be issued, increased, or extended:

          (i) if such issuance, increase, or extension would cause the Letter of Credit Exposure to exceed the lesser of (A) $5,000,000 and (B) an amount equal to the lesser of (1) the aggregate Commitments at such time and (2) the Borrowing Base in effect at such time minus, in each case under this Section 2.10(a)(i)(B), the sum of the aggregate outstanding principal amount of all Advances at such time;

          (ii) if such Letter of Credit has an Expiration Date later than the earlier of (A) one year after the date of issuance thereof (or, in the case of any extension thereof, one year after the date of such extension), and (B) ten days prior to the Maturity Date;

          (iii) unless such Letter of Credit Documents are in form and substance acceptable to the Issuing Lender in its sole discretion;

          (iv) unless such Letter of Credit is a standby letter of credit not supporting the repayment of indebtedness for borrowed money of any Person;

          (v) unless Borrower has delivered to the Issuing Lender a completed and executed Letter of Credit Application; provided that, if the terms of any such Letter of Credit Application conflicts with the terms of this Agreement, the terms of this Agreement shall control;

          (vi) unless such Letter of Credit is governed by (A) the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600, or (B) the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, in either case, including any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Lender;

          (vii) if any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Issuing Lender from issuing such Letter of Credit, or any Legal Requirement applicable to the Issuing Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Lender shall prohibit, or request that the Issuing Lender refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the Issuing Lender with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Lender is not otherwise compensated hereunder) not in effect on the date hereof, or shall impose upon the Issuing Lender any unreimbursed loss, cost

or expense which was not applicable on the date hereof and which the Issuing Lender in good faith deems material to it;

          (viii) if the issuance of such Letter of Credit would violate one or more policies of the Issuing Lender applicable to letters of credit generally;

          (ix) except as otherwise agreed by the Issuing Lender, if Letter of Credit is to be denominated in a currency other than Dollars; or

          (x) a default of any Lender’s obligations to fund under Section 2.10(d) exists or any Lender is at such time a Defaulting Lender hereunder, unless the Issuing Lender has entered into satisfactory arrangements with Borrower or such Lender to eliminate the Issuing Lender’s risk with respect to such Lender.

     (b) Participations. Upon the date of the issuance or increase of a Letter of Credit, the Issuing Lender shall be deemed to have sold to each other Lender having a Commitment and each other Lender having a Commitment shall have been deemed to have purchased from the Issuing Lender a participation in the related Letter of Credit Obligations equal to such Lender’s Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Issuing Lender shall promptly notify each such participant Lender having a Commitment by telephone or facsimile of each Letter of Credit issued, increased, or extended or converted and the actual dollar amount of such Lender’s participation in such Letter of Credit.

     (c) Issuing. Each Letter of Credit shall be issued, increased, or extended pursuant to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter of Credit Application), given not later than 11:00 a.m. (Houston, Texas time) on the fifteenth Business Day before the date of the proposed issuance, increase, or extension of the Letter of Credit (or such later date as may be accepted by the Issuing Lender in its sole discretion), and the Issuing Lender shall give to each other Lender prompt notice thereof by facsimile or telephone. Each Letter of Credit Application shall be delivered by facsimile or by mail specifying the information required therein; provided that if such Letter of Credit Application is delivered by facsimile, Borrower shall follow such facsimile with an original by mail. After the Issuing Lender’s receipt of such Letter of Credit Application (by facsimile or by mail) and upon fulfillment of the applicable conditions set forth in Article III, the Issuing Lender shall issue, increase, or extend, or cause the issuance, increase or extension of, such Letter of Credit for the account of Borrower. Each Letter of Credit Application shall be irrevocable and binding on Borrower.

     (d) Reimbursement. Borrower hereby agrees to either (i) pay on demand to the Issuing Lender an amount equal to any amount paid by the Issuing Lender under any Letter of Credit or (ii) request a Borrowing of References Rate Advances in an amount equal to such amount paid by the Issuing Lender to be made on date the payment is due under such Letter of Credit. In the event the Issuing Lender makes a payment pursuant to a request for draw presented under a Letter of Credit and such payment is not reimbursed by Borrower upon demand under either option provided in the preceding sentence for any reason (including but not limited to the failure to meet the conditions in Section 3.2), then the Issuing Lender shall give

Administrative Agent notice of Borrower’s failure to make such reimbursement and Administrative Agent shall promptly notify each Lender having a Commitment of the amount necessary to reimburse the Issuing Lender. Upon such notice from Administrative Agent, each Lender shall promptly reimburse the Issuing Lender for such Lender’s Pro Rata Share of such amount, and such reimbursement shall be deemed for all purposes of this Agreement to be an Advance to Borrower transferred at Borrower’s request to the Issuing Lender regardless of any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of Default). If such reimbursement is not made by any Lender to the Issuing Lender on the same day on which Administrative Agent notifies such Lender to make reimbursement to the Issuing Lender hereunder, such Lender shall pay interest on its Pro Rata Share thereof to the Issuing Lender at a rate per annum equal to the Federal Funds Rate. Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs Administrative Agent and Lenders to record and otherwise treat such reimbursements to the Issuing Lender as Reference Rate Advances under a Borrowing requested by Borrower to reimburse the Issuing Lender which have been transferred to the Issuing Lender at Borrower’s request.

     (e) Obligations Unconditional. The obligations of Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

          (i) any lack of validity or enforceability of any Letter of Credit Documents;

          (ii) any amendment or waiver of, or any consent to or departure from, any Letter of Credit Documents;

          (iii) the existence of any claim, set off, defense, or other right which Borrower may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Lender, or any other person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents, or any unrelated transaction;

          (iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

          (v) payment by the Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

          (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of Borrower in connection with the Letters of Credit or Borrower’s rights under Section 2.10(f).

     (f) Liability of Issuing Lender. Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Lender nor any of its officers or directors shall be liable or responsible for:

          (i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

          (ii) the validity, sufficiency, or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent, or forged;

          (iii) payment by the Issuing Lender against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

          (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING THE ISSUING LENDER’S OWN NEGLIGENCE),

except that Borrower shall have a claim against the Issuing Lender, and the Issuing Lender shall be liable to Borrower, to the extent of any direct, as opposed to consequential, damages suffered by Borrower which a court determines in a final, non-appealable judgment were caused by the Issuing Lender’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

     (g) Cash Collateral Account.

          (i) If Borrower is required to deposit funds in the Cash Collateral Account pursuant to Section 2.6(c), 2.7(b), 7.2(b) or 7.3(b), then Borrower and the Issuing Lender shall establish the Cash Collateral Account and Borrower shall execute any documents and agreements, including the Issuing Lender’s standard form assignment of deposit accounts, that the Issuing Lender requests in connection therewith to establish the Cash Collateral Account and grant the Issuing Lender a first priority security interest in such account and the funds therein. Borrower hereby pledges to the Issuing Lender and grants the Issuing Lender a security interest in the Cash Collateral Account, whenever established, all funds held in the Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Obligations.

          (ii) So long as no Default exists, the Issuing Lender may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and the Issuing Lender shall release to Borrower at Borrower’s written request any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any

Default, the Issuing Lender may apply any funds held in the Cash Collateral Account to the Obligations in the order set forth in Section 7.6.

          (iii) The Issuing Lender shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Issuing Lender accords its own Property, it being understood that the Issuing Lender shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

     (h) Defaulting Lender. If, at any time, a Defaulting Lender exists hereunder, then, at the request of the Issuing Lender, Borrower shall deposit funds with Administrative Agent into the Cash Collateral Account in an amount equal to such Defaulting Lender’s Pro Rata Share of the Letter of Credit Exposure.

     Section 2.11. Time and Place of Payments. All payments to be made by Borrower to Administrative Agent under this Agreement will be made to the following account (the “Project Account”) by wire transfer in immediately available funds not later than 11:00 a.m., Houston, Texas, time on the date due:

Account: Bank of New York                 New York, NY 10004                 ABA # 021000018

Favour: Macquarie Bank Limited – OBU Sydney               Sydney               A/C No.: 8900055375               Chips UID: 236386               Reference: Delta Petroleum Corporation

or to any other account that Administrative Agent may designate in writing to Borrower from time to time.

     Section 2.12. Borrower Sub-Account; Disbursements.

     (a) Borrower Sub-Account. Following the date on which the first Advance under the Term Loan is made and continuing until all Advances under the Term Loan have been paid in full in cash, Borrower will direct and cause Operator, all purchasers of Hydrocarbons and all other customers and obligors of Borrower (including all payors of Royalty Interests, net profit interests, and production payment interests) to deposit directly into the Project Account all payments of any nature due and owing to Borrower. If Borrower nonetheless receives any such funds, it will promptly (but, in any event, by the end of the following third (3^rd) Business Day) deposit all such funds in the Project Account. This Section 2.12 will not prohibit Operator from making payments directly to Royalty Interest owners and other third party payees who are not Affiliates of Borrower. Administrative Agent will establish a sub account (the “Borrower Sub-Account”) on its internal books and records and credit to the Borrower Sub-Account all funds collected in the Project Account and attributable to Borrower’s Net Revenue Interest in the Oil

and Gas Properties at the time the amount to be credited has been identified to Administrative Agent’s reasonable satisfaction. Borrower hereby irrevocably authorizes Administrative Agent to debit the Borrower Sub-Account for (i) the payment of all Obligations when due, and (ii) for any and all outstanding accrued interest existing on the date of said debit, provided, however, any interest paid under this Section 2.12(a)(ii) in any month will also be deducted under Section 2.8 for purposes of calculating Net Operating Cash Flow for said month. Administrative Agent may, if an Event of Default exists, apply all funds credited to the Borrower Sub-Account against any Obligations then outstanding.

     (b) Disbursement of Operating Expenses. Following its delivery of each monthly Property Operating Statement to Administrative Agent, Borrower may, not more than four times each month and on at least three Business Days written notice, request a release of funds credited to the Borrower Sub-Account since the preceding Payment Date to pay:

          (i) the items described in clauses (a)–(f) of the definition of Net Operating Cash Flow and payable in the Reported Month covered by the POS; and

          (ii) any other payments or distributions Approved by Administrative Agent;

but only if no Event of Default exists or would result from the release of the requested funds. Borrower’s request will include supporting documentation reasonably satisfactory to Administrative Agent, including Borrower’s monthly joint interest billing invoices and revenue distribution statements. Unless Administrative Agent notifies Borrower in writing within that three Business Day period that it objects or requires additional information with respect to the requested disbursement (in which case, Administrative Agent will describe the objection or requested information in reasonable detail), then Administrative Agent will process the disbursement request and release the requested funds from the Borrower Sub-Account. Borrower will use funds returned to it under this Section 2.12(b) exclusively to pay the amounts included in its disbursement request and will, at the request of Administrative Agent, promptly document to the satisfaction of Administrative Agent that those amounts have been paid. A Responsible Officer shall make any request under this Section.

     (c) Amounts Owed to Third Parties; Taxes. Amounts deposited into the Project Account and owing to (i) Working Interest and Royalty Interest owners that are not Affiliates of Borrower, or (ii) Governmental Authorities for taxes or payments measured by production will be released by Administrative Agent to Borrower upon receipt of a certificate from Borrower detailing the amounts and the party to be paid. If an Event of Default exists, however, Administrative Agent will, at its option and upon notice to Borrower, have the right (but not the obligation) to make payments directly to the Persons identified on Borrower’s certificate. A Responsible Officer shall deliver the certificate contemplated by this Section 2.12(c) on behalf of Borrower.

     (d) Administrative Agent’s Right to Audit. Administrative Agent will have the right to undertake audit procedures during normal business hours and upon prior notice to periodically confirm that the payments described in Sections 2.12(b) and 2.12(c) have been made by Borrower.

     (e) Debt Service Reserve Account. At least once per month and at least 3 Business Days prior to the Payment Date, Borrower may request that Administrative Agent reserve funds from the Borrower Sub-Account related to anticipated disbursement for items covered by Section 2.12(b) above, and place such funds into a separate account. Administrative Agent will establish a sub-account on its internal books and records for such purpose (the “Debt Service Reserve Account”). Borrower may, not more than twice each month and on at least three Business Days written notice, request a release of funds remaining in the Debt Service Reserve Account to pay (A) regularly scheduled interest payments under the Convertible Notes and the Senior Unsecured Notes in accordance with Section 6.5; and (B) any other payments or distributions Approved by Administrative Agent, in each case only if no Event of Default exists or would result from the release of the requested funds. Borrower’s request will include supporting documentation reasonably satisfactory to Administrative Agent. Unless Administrative Agent notifies Borrower in writing within that three Business Day period that it objects or requires additional information with respect to any requested disbursement under subparagraph (B) above (in which case, Administrative Agent will describe the objection or requested information in reasonable detail), then Administrative Agent will process each disbursement request and release the requested funds from the Debt Service Reserve Account. Borrower will use funds returned to it under this Section 2.12(e) exclusively to pay the amounts included in its disbursement request and will, at the request of Administrative Agent, promptly document to the satisfaction of Administrative Agent that those amounts have been paid. A Responsible Officer shall make any request under this Section.

     Section 2.13. Fees.

     (a) Commitment Fees. Borrower agrees to pay to Administrative Agent, for the account of each Lender, a commitment fee at a per annum rate equal to the Commitment Fee Rate on the daily Unused Commitment Amount of such Lender, from the Effective Date until the Commitment Termination Date; provided that, no Commitment Fee shall accrue on the Commitment of a Defaulting Lender during the period such Lender remains a Defaulting Lender. The commitment fees shall be due and payable quarterly in arrears on the last day of each March, June, September, and December commencing on December 31, 2010 and continuing thereafter through and including the Commitment Termination Date.

     (b) Letter of Credit Fees.

          (i) Borrower agrees to pay to Administrative Agent for the pro rata benefit of Lenders a per annum letter of credit fee for each Letter of Credit issued hereunder in an amount equal to the Applicable Margin then in effect for Eurodollar Rate Advances times the daily maximum amount available to be drawn under such Letter of Credit, payable quarterly in arrears on the last day of each March, June, September, and December commencing on March 31, 2011 and continuing thereafter through and including the Commitment Termination Date.

          (ii) Borrower also agrees to pay to the Issuing Lender such other usual and customary fees associated with any transfers, amendments, drawings, negotiations or reissuances of any Letters of Credit.

     (c) Upfront Fees. Borrower agrees to pay to Administrative Agent for the account of each Lender a fee for commitments to fund under the Term Loan equal to 2% of the amount of any incremental increase in the amount Lenders commit to fund at any time under the Term Loan above the committed amount of the Term Loan previously in effect pursuant to a commitment to fund under Section 2.3.

     Section 2.14. Interest. Borrower shall pay interest on the unpaid principal amount of each Advance made by each Lender from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

     (a) Reference Rate Advances. If such Advance is a Reference Rate Advance, a rate per annum equal at all times to the Adjusted Reference Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable quarterly in arrears on the last day of each fiscal quarter commencing on March 31, 2011, and on the date such Reference Rate Advance shall be paid in full.

     (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of such Interest Period.

     (c) Usury Recapture.

          (i) If, with respect to any Lender, the effective rate of interest contracted for under the Loan Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Loan Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Lender hereunder shall bear interest at a rate which would make the effective rate of interest for such Lender under the Loan Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the “Lost Interest”) has been recaptured by such Lender.

          (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Lender pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Lender the interest rates charged under Section 2.14 hereunder shall be retroactively increased such that the effective rate of interest under the Loan Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, Borrower shall pay to such Lender the amount of the Lost Interest remaining to be recaptured by such Lender.

          (iii) Notwithstanding the foregoing or any other term in this Agreement and the Loan Documents to the contrary, it is the intention of each Lender and Borrower to conform strictly to any applicable usury laws. Accordingly, if any Lender contracts for, charges, or receives any consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall be canceled automatically and, if previously paid, shall at such Lender’s option

be applied to the outstanding principal amount of the loans made hereunder by such Lender or be refunded to Borrower.

     Section 2.15. Payments and Computations.

     (a) Payment Procedures. Borrower shall make each payment under this Agreement and under the Notes not later than 11:00 a.m. (Houston, Texas time) on the day when due in Dollars to Administrative Agent as set forth in Section 2.11 in same day funds without deduction, setoff, or counterclaim of any kind, except as may be applicable to any Defaulting Lender. Administrative Agent shall promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to Administrative Agent, the Issuing Lender, or a specific Lender pursuant to Sections 2.14(c), 2.17, 2.18, 2.19, 8.5, 9.7, but after taking into account payments effected pursuant to Section 9.4) in accordance with each Lender’s Pro Rata Share to Lenders for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or the Issuing Lender to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement.

     (b) Computations. All computations of interest based on the Reference Rate and of fees shall be made by Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds Rate shall be made by Administrative Agent, on the basis of a year of 360 days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error.

     (c) Non Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the immediately preceding Business Day and such shortening of time shall in such case be included in the computation of payment of interest or fees, as the case may be.

     (d) Administrative Agent Reliance. Unless Administrative Agent shall have received written notice from Borrower prior to the date on which any payment is due to Lenders that Borrower shall not make such payment in full, Administrative Agent may assume that Borrower has made such payment in full to Administrative Agent on such date and Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such date an amount equal to the amount then due such Lender. If and to the extent Borrower shall not have so made such payment in full to Administrative Agent, each Lender shall repay to Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to Administrative Agent, at the Federal Funds Rate for such day.

     Section 2.16. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set off, or otherwise) on account of the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share of payments on account of the Advances or Letter of Credit Obligations obtained by all Lenders (other than as a result of a termination of a Defaulting Lender’s Commitment under Section 2.6(c)), such Lender shall notify Administrative Agent and forthwith purchase from the other Lenders such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.16 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set off) with respect to such participation as fully as if such Lender were the direct creditor of Borrower in the amount of such participation. The provisions of this Section 2.16 shall not be construed to apply to any payment made by Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Advances or participations in Letter of Credit Exposure to any assignee or participant, other than to Borrower or any Guarantor or Affiliate thereof (as to which the provisions of this Section 2.16 shall apply). If a Lender fails to make an Advance with respect to a Borrowing as and when required hereunder and Borrower subsequently makes a repayment of any Advances, such repayment shall be split among the non-defaulting Lenders ratably in accordance with their respective Commitment percentages until each Lender (including the Defaulting Lender) has its percentage of all of the outstanding Advances and the balance of such repayment shall be applied among Lenders in accordance with their Pro Rata Share.

     Section 2.17. Breakage Costs. If (a) any payment of principal of any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, whether as a result of any payment pursuant to Section 2.7, the acceleration of the maturity of the Notes pursuant to Article VII, or otherwise, or (b) Borrower fails to make a principal or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable, Borrower shall, within 10 days of any written demand sent by any Lender to Borrower through Administrative Agent, pay to Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, out of pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

     Section 2.18. Increased Costs.

     (a) Increased Costs Generally. If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Eurodollar Rate) or the Issuing Lender;

          (ii) subject any Lender or the Issuing Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Rate Advance made by it, or change the basis of taxation of payments to such Lender or the Issuing Lender in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 2.19 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the Issuing Lender); or

          (iii) impose on any Lender or the Issuing Lender or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Rate Advances made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or Issuing Lender of making or maintaining any Eurodollar Rate Advance (or of maintaining its obligation to make any such Eurodollar Rate Advance), or to increase the cost to such Lender or the Issuing Lender of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the Issuing Lender hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or the Issuing Lender, Borrower will pay to such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered.

     (b) Capital Requirements. If any Lender or the Issuing Lender determines that any Change in Law affecting such Lender or the Issuing Lender or any lending office of such Lender or such Lender’s or the Issuing Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Lender’s capital or on the capital of such Lender’s or the Issuing Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender , or the Letters of Credit issued by the Issuing Lender, to a level below that which such Lender or the Issuing Lender or such Lender’s or the Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Lender’s policies and the policies of such Lender’s or the Issuing Lender’s holding company with respect to capital adequacy), then from time to time Borrower will pay to such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender or such Lender’s or the Issuing Lender’s holding company for any such reduction suffered.

     (c) Letters of Credit. If any Change in Law shall either impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, the Issuing Lender or impose on the Issuing Lender any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to the Issuing Lender of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by the Issuing Lender’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by the Issuing Lender, Borrower shall pay to the Issuing Lender, from time to time as specified by the Issuing Lender, additional amounts which shall be sufficient to compensate the Issuing Lender for such increased cost.

     (d) Delay in Requests. Failure or delay on the part of any Lender or the Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender or the Issuing Lender’s right to demand such compensation, provided that Borrower shall not be required to compensate a Lender or the Issuing Lender pursuant to this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender or the Issuing Lender, as the case may be, notifies Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof).

     (e) Mitigation. If any Lender requests compensation under Section 2.18, or requires Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.19, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.18 or Section 2.19, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Borrower hereby agrees to pay all costs and expenses incurred by any Lender in connection with any such designation or assignment.

     (f) Certificates for Reimbursement. A certificate of a Lender or the Issuing Lender setting forth the amount or amounts necessary to compensate such Lender or the Issuing Lender or its holding company, as the case may be, as specified in paragraph (a), (b) or (c) of this Section and delivered to Borrower shall be conclusive absent manifest error. Borrower shall pay such Lender or the Issuing Lender, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

     Section 2.19. Taxes.

     (a) Taxes Not Deducted from Payments to Lenders. All payments made by Borrower under this Agreement will be made free and clear of and without deduction for Indemnified Taxes. If Borrower is required by law to deduct any Indemnified Taxes from any sum payable to any Lender, (i) the sum payable will be increased by an amount so that, after making all required

deductions (including deductions applicable to additional sums payable under this Section 2.19(a)) each Lender will receive an amount equal to the sum it would have received had no deductions been made, (ii) Borrower will deduct from the sum payable to each Lender an amount sufficient to pay the Taxes and pay the balance to such Lender, and (iii) Borrower will promptly pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

     (b) Other Taxes. In addition, and to the fullest extent permitted by Law, Borrower agrees to pay any Other Taxes.

     (c) INDEMNIFICATION. WITHOUT DUPLICATION OF ITS OBLIGATION TO PAY INCREASED AMOUNTS PURSUANT TO SECTION 2.19(a) AND (b), AND SUBJECT TO SECTION 2.19(i), TO TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EXCEPT AS PROVIDED IN SECTION 2.19(e) BELOW, AND UNLESS THERE EXISTS A MATERIAL BREACH OF LENDERS’ REPRESENTATIONS IN THIS AGREEMENT, BORROWER WILL FOREVER INDEMNIFY ADMINISTRATIVE AGENT, ISSUING LENDER AND LENDERS FROM AND AGAINST (I) ALL TAXES AND OTHER TAXES IMPOSED BY ANY TAXING AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 2.19 AND PAID BY ADMINISTRATIVE AGENT, ISSUING LENDER OR ANY LENDER ON BEHALF OF BORROWER AND (II) ALL LIABILITIES (INCLUDING PENALTIES, INTEREST AND REASONABLE ATTORNEYS FEES, EXPENSES AND DISBURSEMENTS) ARISING FROM OR RELATED TO THOSE TAXES AND OTHER TAXES WITHOUT REGARD TO WHETHER THOSE TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY IMPOSED. BORROWER WILL MAKE ANY PAYMENTS REQUIRED UNDER THIS SECTION 2.19(c) WITHIN 30 DAYS AFTER THE ADMINISTRATIVE AGENT OR ANY LENDER DELIVERS A WRITTEN NOTICE TO BORROWER THAT (X) IDENTIFIES THE RELEVANT GOVERNMENTAL AUTHORITY AND THE AMOUNT OF THE TAX OR OTHER TAX IMPOSED, (Y) STATES WITH REASONABLE SPECIFICITY THE BASIS FOR THAT TAX OR OTHER TAX, AND (Z) CERTIFIES THAT ADMINISTRATIVE AGENT OR SUCH LENDER HAS PAID THE TAX OR OTHER TAX IMPOSED. THE INDEMNIFICATION OBLIGATIONS OF BORROWER UNDER THIS SECTION 2.19(C) WILL SURVIVE THE REPAYMENT OF THE OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

     (d) Certification of Tax Status By Any Lender. Each Lender will promptly (i) execute and deliver to Borrower a duly completed copy of United States Internal Revenue Service Form W 8BEN, W-81MY or W-8ECI (as applicable), certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and (ii) deliver to Borrower a United States Internal Revenue Service Form W-8 or W-9 (as applicable) and certify that such Lender is entitled to an exemption from United States backup withholding tax. Each Lender further agrees to deliver to Borrower (x) renewals or additional copies of such forms (or any successor forms) on or before the date that such forms expire or become obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms delivered by it, additional forms or amendments to those forms as may be reasonably requested by Borrower. All forms or amendments described in the preceding sentence will include a certification by each Lender that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal

income taxes, unless an event (including a change in applicable law) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises Borrower in writing that such Lender is not capable of receiving payments without any deduction or withholding of United States federal income tax.

     (e) Certain Events Not Entitled to Indemnification. For any period during which any Lender has failed to provide Borrower with an appropriate form pursuant to Section 2.19(d) above (and unless the failure is due to a change in applicable law or a change in the interpretation or administration of any applicable law by any Governmental Authority, occurring after the date on which a form was required to be provided), such Lender will not be entitled to indemnification under this Section 2.19 with respect to Taxes imposed by the United States. If, however, a Lender becomes subject to Taxes because of its failure to deliver a form required under Section 2.19(d) above, Borrower shall take such steps as such Lender may reasonably request to assist such Lender in recovering those Taxes.

     (f) Documentation of Exemptions. If any Lender is entitled to an exemption from or reduction of withholding tax with respect to payments under any Loan Document pursuant to applicable law of any relevant jurisdiction, such Lender will deliver to Borrower, at the time or times prescribed by applicable aw, properly completed and executed documentation required by law so as to permit those payments to be made without withholding or at a reduced rate of withholding.

     (g) Indemnification By Lender for Certain Tax Claims. If the United States Internal Revenue Service or any other Governmental Authority asserts a claim against Borrower alleging that it did not properly withhold tax from amounts paid to or for the account of any Lender (for any reason, including because the relevant form was not delivered or was not properly completed or because such Lender failed to notify Borrower of a change in circumstances that rendered its exemption from withholding ineffective), then such Lender will indemnify Borrower from and against all amounts paid, directly or indirectly, by Borrower as tax or withholding for any tax (and including reasonable attorneys fees, expenses and disbursements together with penalties and interest imposed by Governmental Authority on amounts payable to Borrower under this subsection). The indemnification obligations of any Lender under this Section 2.19(g) will survive the repayment of the Obligations and the termination of this Agreement.

     (h) Designation of Substitute Lending Office. Each Lender will, at Borrower’s request following the occurrence of any event giving rise to the operation of this Section 2.19, use commercially reasonable efforts (subject to overall policy considerations of such Lender) to designate a substitute lending office, but provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of this Section 2.19. Nothing in this Section 2.19(h) will affect or postpone any of the obligations of Borrower or the rights of any Lender provided in this section.

     (i) Effect of Tax Refund. Each Lender will use its commercially reasonable efforts to obtain in a timely fashion any refund, deduction or credit of any Taxes or Other Taxes paid or

reimbursed by Borrower pursuant to this Section 2.19. If any Lender receives a benefit in the nature of a refund, deduction or credit (including a refund in the form of a deduction from or credit against taxes that are otherwise payable by a Lender) of any Taxes or Other Taxes with respect to which Borrower have made a payment under this Section 2.19, such Lender will notify and reimburse Borrower (promptly after such Lender reasonably determines that such refund, deduction or credit has become final) to the extent of the benefit of such refund, deduction or credit, including any interest paid by the relevant Governmental Authority. Nothing in this Section 2.19 will, however, require any Lender to make available its tax returns (or any other information relating to its taxes which it deems to be confidential) or to attempt to obtain any refund, deduction or credit (including any interest paid by the relevant Governmental Authority and received by any Lender), if any Lender determines that doing so could be inconsistent with any reporting position otherwise taken by such Lender on its tax returns.

     Section 2.20. Replacement of Lender. If any Lender requests compensation under Section 2.18(a) or Section 2.18(b), (a) any Lender suspends its obligation to continue, or Convert Advances into, Eurodollar Rate Advances pursuant to Section 2.5(c)(ii) or Section 2.16, any Lender becomes a Defaulting Lender, or (b) any Lender is a Non-Consenting Lender (any such Lender, a “Subject Lender”), then (i) in the case of a Defaulting Lender, Administrative Agent may, upon notice to the Subject Lender and Borrower, require such Subject Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.6), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which Eligible Assignee may be another Lender, if a Lender accepts such assignment) and (ii) in the case of any Subject Lender, including a Defaulting Lender, Borrower may, upon notice to the Subject Lender and Administrative Agent and at Borrower’s sole cost and expense, require such Subject Lender to assign, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.6), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

          (A) as to assignments required by Borrower, Borrower shall have paid to Administrative Agent the assignment fee specified in Section 9.6;

          (B) such Subject Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in outstanding Letter of Credit Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.17) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or Borrower (in the case of all other amounts);

          (C) in the case of any such assignment resulting from a claim for compensation under Section 2.18, such assignment will result in a reduction in such compensation or payments thereafter;

          (D) such assignment does not conflict with applicable Legal Requirements; and

          (E) with respect to a Non-Consenting Lender, the proposed agreement, amendment, waiver, consent or release with respect to this Agreement or any other Loan Document (including any increases to the Borrowing Base) has been Approved by the Required Lenders and such agreement, amendment, waiver, consent or release can be effected as a result of the assignment contemplated by this Section.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply. Solely for purposes of effecting the assignment required for a Defaulting Lender under this Section 2.20 and to the extent permitted under applicable Legal Requirements, each Lender hereby designates and appoints Administrative Agent as true and lawful agent and attorney-in-fact, with full power and authority, for and on behalf of and in the name of such Lender to execute, acknowledge and deliver the Assignment and Acceptance required hereunder if such Lender was a Defaulting Lender and such Lender shall be bound thereby as fully and effectively as if such Lender had personally executed, acknowledged and delivered the same. In lieu of Borrower or Administrative Agent replacing a Defaulting Lender as provided in this Section 2.20, Borrower may terminate such Defaulting Lender’s Commitment as provided in Section 2.6.

     Section 4.3. Authorization and Approvals. No consent, order, authorization, or approval or other action by, and no notice to or filing with, any Governmental Authority or any other Person is required for the due execution, delivery, and performance by Borrower of this Agreement, the Notes, or the other Loan Documents to which Borrower is a party or by each Guarantor of its Guaranty or the other Loan Documents to which it is a party or the consummation of the transactions contemplated thereby, except for (a) the filing of UCC-1 financing statements and Mortgages in the state and county filing offices and (b) those consents and approvals that have been obtained or made on or prior to the date hereof and that are in full force and effect.

     Section 4.6. True and Complete Disclosure. All factual information (excluding estimates, projections and proforma financial information) heretofore or contemporaneously furnished by or on behalf of Borrower or any of the Guarantors in writing to any Lender or Administrative Agent for purposes of or in connection with this Agreement, any other Loan Document or any transaction contemplated hereby or thereby is, and all other such factual information hereafter furnished by or on behalf of Borrower and the Guarantors in writing to Administrative Agent or any of the Lenders was or shall be, true and accurate in all material respects on the date as of which such information was or is dated or certified and did not or does not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements contained therein not misleading at such time.

     Section 4.7. Litigation; Compliance with Laws.

     (a) There is no pending or, to the knowledge of Borrower, threatened action or proceeding affecting Borrower or any of the Guarantors before any court, Governmental Authority or arbitrator which could reasonably be expected to cause a Material Adverse Change other than as set forth in Schedule 4.7 or which purports to affect the legality, validity, binding effect or enforceability of this Agreement, any Note, or any other Loan Document. As of the Effective Date, there is no pending or, to the knowledge of Borrower, threatened action or proceeding instituted against Borrower or any of the Guarantors which seeks to adjudicate Borrower or any of the Guarantors as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property.

     (b) Borrower and the Guarantors have complied in all material respects with all material statutes, rules, regulations, orders and restrictions of any Governmental Authority having jurisdiction over the conduct of their respective businesses or the ownership of their respective Property.

     Section 4.8. Use of Proceeds. The proceeds of the Advances will be used by Borrower for the purposes described in Section 5.9. Neither Borrower nor any Guarantor is engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U). No proceeds of any Advance will be used to purchase or carry any margin stock in violation of Regulation T, U or X.

     Section 4.9. Investment Company Act. Neither Borrower nor any of the Guarantors is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

     Section 4.10. Taxes.

     (a) Reports and Payments. All Returns (as defined below in clause (c) of this Section) required to be filed by or on behalf of Borrower, the Guarantors, or any member of the Controlled Group (hereafter collectively called the “Tax Group”) have been duly filed on a timely basis or appropriate extensions have been obtained and such Returns are and will be true, complete and correct, except where the failure to so file would not be reasonably expected to cause a Material Adverse Change; and all Taxes shown to be payable on the Returns or on subsequent assessments with respect thereto will have been paid in full on a timely basis, and no other Taxes will be payable by the Tax Group with respect to items or periods covered by such Returns, except in each case to the extent of (i) reserves reflected in the Financial Statements and the Interim Financial Statements, or (ii) Taxes that are being contested in good faith. The reserves for accrued Taxes reflected in the financial statements delivered to Lenders under this Agreement are adequate in the aggregate for the payment of all unpaid Taxes, whether or not disputed, for the period ended as of the date thereof and for any period prior thereto, and for which the Tax Group may be liable in its own right, as withholding agent or as a transferee of the assets of, or successor to, any Person.

     (b) Taxes Definition. “Taxes” in this Section 4.10 shall mean all taxes, charges, fees, levies, or other assessments imposed by any federal, state, local, or foreign taxing authority, including without limitation, income, gross receipts, excise, real or personal property, sales, occupation, use, service, leasing, environmental, value added, transfer, payroll, and franchise taxes (and including any interest, penalties, or additions to tax attributable to or imposed on with respect to any such assessment).

     (c) Returns Definition. “Returns” in this Section 4.10 shall mean any federal, state, local, or foreign report, declaration of estimated Tax, information statement or return relating to, or required to be filed in connection with, any Taxes, including any information return or report with respect to backup withholding or other payments of third parties.

     Section 4.11. Pension Plans. All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan,

and each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. No “accumulated funding deficiency” (as defined in Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of the Code. No Reportable Event under Section 4043 of ERISA and the regulations issued thereunder has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits. Neither Borrower nor any member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of the most recent valuation date applicable thereto, neither Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if Borrower or any member of the Controlled Group has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, Borrower has no reason to believe that the annual cost during the term of this Agreement to Borrower or any member of the Controlled Group for post-retirement benefits to be provided to the current and former employees of Borrower or any member of the Controlled Group under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

     Section 4.12. Condition of Property; Casualties. Each of Borrower and the Guarantors has good and defensible title to, or valid leasehold interest in, all of its Oil and Gas Properties as is customary in the oil and gas industry in all material respects, free and clear of all Liens except for Permitted Liens. Each of Borrower and the Guarantors has good title to, or valid leasehold interest in, all of its other material Properties, free and clear of all Liens except for Permitted Liens. The material Properties used or to be used in the continuing operations of Borrower and each of the Guarantors are in good repair, working order and condition, normal wear and tear excepted. Since December 31, 2009, neither the business nor the material Properties of Borrower and each of the Guarantors, taken as a whole, has been materially and adversely affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts, Permits, or concessions by a Governmental Authority, riot, activities of armed forces, or acts of God or of any public enemy.

     Section 4.13. No Burdensome Restrictions; No Defaults.

     (a) Other than those identified on Schedule 4.13(a), neither Borrower nor any Guarantor is a party to any indenture, loan, or credit agreement or any lease or other agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation that could reasonably be expected to cause a Material Adverse Change.

     (a) may treat the payee of any Note as the holder thereof until Administrative Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to Administrative Agent;

     (b) may consult with legal counsel (including counsel for Borrower), independent public accountants, and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants, or experts;

     Section 8.3. Administrative Agent and Its Affiliates. With respect to its Commitment, the Advances made by it and the Notes issued to it, Administrative Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not Administrative Agent. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Administrative Agent in its individual capacity. Administrative Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, Borrower or any of its Subsidiaries, and any Person who may do business with or own securities of Borrower or any such Subsidiary, all as if Administrative Agent were not an agent hereunder and without any duty to account therefor to Lenders.

     Section 8.4. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon Administrative Agent or any other Lender and based on the Financial Statements and the Interim Financial Statements and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it shall, independently and without reliance upon Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

     Section 8.5. Indemnification. LENDERS SEVERALLY AGREE TO INDEMNIFY ADMINISTRATIVE AGENT AND THE ISSUING LENDER AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS (TO THE EXTENT NOT REIMBURSED BY BORROWER), ACCORDING TO THEIR RESPECTIVE PRO RATA SHARES FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST ADMINISTRATIVE AGENT AND THE ISSUING LENDER IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY ACTION TAKEN OR OMITTED BY ADMINISTRATIVE AGENT OR THE ISSUING LENDER UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (INCLUDING ADMINISTRATIVE AGENT’S AND THE ISSUING LENDER’S OWN NEGLIGENCE), AND INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL CLAIMS AND ANY LIABILITIES ARISING UNDER ENVIRONMENTAL LAW, PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR DISBURSEMENTS RESULTING FROM ADMINISTRATIVE AGENT’S OR THE ISSUING LENDER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AS DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT. WITHOUT LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE ADMINISTRATIVE AGENT AND THE ISSUING LENDER PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE OF ANY OUT OF POCKET EXPENSES (INCLUDING COUNSEL FEES) INCURRED BY ADMINISTRATIVE AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT, OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS, OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, TO THE EXTENT THAT ADMINISTRATIVE AGENT OR THE ISSUING LENDER IS NOT REIMBURSED FOR SUCH BY BORROWER. To the extent that the indemnity obligations provided in this Section 8.5 are for the benefit of Administrative Agent as the named secured party under the Liens granted under the Security Instruments, each Lender hereby agrees that if such Lender ceases to be a Lender hereunder but Obligations owing to such Lender or an Affiliate of such Lender continue to be secured by such Liens, then such Lender shall continue to be bound by the provisions of this Section 8.5 until such time as such Obligations have been satisfied or terminated in full and subject to the terms of the last sentence of Section 9.9. In such event, in determining the pro rata shares under this Section 8.5, Lenders shall include the aggregate

amount (giving effect to any netting agreements) that would be owing to such Hedge Counterparty if such Hedge Contracts were terminated at the time of determination.

     Section 8.6. Successor Administrative Agent and Issuing Lender. Administrative Agent or the Issuing Lender may resign at any time by giving written notice thereof to Lenders and Borrower and may be removed at any time with or without cause by the Required Lenders upon receipt of written notice from the Required Lenders to such effect. Upon receipt of notice of any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, if no Event of Default has occurred and is continuing, the consent of Borrower, which consent shall not be unreasonably withheld. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Required Lenders with the consent of Borrower, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s or Issuing Lender’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent or Issuing Lender, then the retiring Administrative Agent or Issuing Lender may, on behalf of Lenders and Borrower, appoint a successor Administrative Agent or Issuing Lender, which shall be, in the case of a successor agent, a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000.00 and, in the case of the Issuing Lender, a Lender; provided that, if Administrative Agent or Issuing Lender shall notify Borrower and Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that (i) in the case of any collateral security held by Administrative Agent on behalf of Lenders or the Issuing Lender under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed and (ii) the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit) and (b) all payments, communications and determinations provided to be made by, to or through the retiring Administrative Agent shall instead be made by or to each Lender and the Issuing Lender directly, until such time as the Required Lenders appoint a successor Administrative Agent or Issuing Lender, as applicable, as provided for above in this paragraph. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Administrative Agent or Issuing Lender, and the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent’s or Issuing Lender’s resignation or removal hereunder as Administrative Agent or Issuing Lender, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Loan Documents.

     Section 8.7. Collateral Matters.

     (a) Administrative Agent is authorized on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any actions with respect to any Collateral or Security Instruments which may be necessary to perfect and maintain Acceptable Security Interests in and Liens upon the Collateral granted pursuant to the Security Instruments. Administrative Agent is further authorized on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any action (other than enforcement actions requiring the consent of, or request by, the Required Lenders as set forth in Section 7.2 or Section 7.3) in exigent circumstances as may be reasonably necessary to preserve any rights or privileges of the Secured Parties under the Loan Documents or applicable law. By accepting the benefit of the Liens granted pursuant to the Security Instruments, each Secured Party not party hereto hereby agrees to the terms of this paragraph (a).

     (b) Each Secured Party irrevocably authorizes Administrative Agent to release any Lien granted to or held by Administrative Agent upon any Collateral: (i) upon termination of the Commitments, termination or expiration of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to Administrative Agent and the Issuing Lender have been made), termination of all Hedge Contracts with Hedge Counterparties that are secured by the Liens on the Collateral (other than Hedge Contracts with any Hedge Counterparty with respect to which other arrangements satisfactory to the Hedge Counterparty and Borrower have been made; provided that, unless a Hedge Counterparty (other than the Person that may be serving as Administrative Agent) notifies Administrative Agent in writing at least 2 Business Days prior to the expected termination of the Commitments that such arrangements have not been made, then solely for purposes of this paragraph (b), it shall be deemed that such satisfactory arrangements have been made; provided further that, the immediately preceding proviso shall not apply unless Administrative Agent or Borrower shall have given such Hedge Counterparty written notice of such expected termination of Commitments at least 10 Business Days prior to the expected date of termination), and payment in full of all Obligations (other than Obligations arising under Hedge Contracts with any Hedge Counterparty with respect to which other arrangements satisfactory to the Hedge Counterparty and Borrower have been made; provided that, unless a Hedge Counterparty (other than the Person that may be serving as Administrative Agent) notifies Administrative Agent in writing at least 2 Business Days prior to the expected termination of the Commitments that such arrangements have not been made, then solely for purposes of this clause (b), it shall be deemed that such satisfactory arrangements have been made; provided further that, the immediately preceding proviso shall not apply unless Administrative Agent or Borrower shall have given such Hedge Counterparty written notice of such expected termination of Commitments at least 10 Business Days prior to the expected date of termination); (ii) constituting Property sold or to be sold or otherwise disposed of as part of or in connection with any Disposition permitted under this Agreement or the other Loan Documents; (iii) constituting Property in which Borrower or any Guarantor owned no interest at the time the Lien was granted or at any time thereafter; (iv) constituting Property leased to Borrower or any Guarantor under a lease which has expired or has been terminated in a transaction permitted under this Agreement or is about to expire and which has not been, and is not intended by Borrower or such Guarantor to be, renewed or extended; or (v) if Approved, authorized or ratified in writing by the applicable Required Lenders or all Lenders, as the case may be, as required by Section 9.1. Upon the

request of Administrative Agent at any time, the Secured Parties will confirm in writing Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 8.7. By accepting the benefit of the Liens granted pursuant to the Security Instruments, each Secured Party not party hereto hereby agrees to the terms of this paragraph (b).

     (c) Notwithstanding anything contained in any of the Loan Documents to the contrary, Borrower, Administrative Agent, and each Secured Party hereby agree that no Secured Party shall have any right individually to realize upon any of the Collateral or to enforce the Guaranties, it being understood and agreed that all powers, rights and remedies hereunder and under the Security Instruments may be exercised solely by Administrative Agent on behalf of the Secured Parties in accordance with the terms hereof. By accepting the benefit of the Liens granted pursuant to the Security Instruments, to the extent a Secured Party is not a party hereto, it agrees to the terms of this paragraph (c).

The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and Borrower, Administrative Agent, the Issuing Lender, and Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

     (b) Waiver of Damages. To the fullest extent permitted by applicable law, Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Advance or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in Section 9.7(a) shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart signature page of this Agreement by facsimile is as effective as executing and delivering this Agreement in the presence of the other parties to this Agreement.

     Section 9.9. Survival of Representations, Etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of Borrower in connection herewith shall survive the execution and delivery of this Agreement and the Loan Documents, the making of the Advances and any investigation made by or on behalf of Lenders, none of

which investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of Borrower provided for in Sections 2.17, 2.18, 2.19, 9.4 and 9.7 and all of the obligations of Lenders in Section 8.5 shall survive any termination of this Agreement and repayment in full of the Obligations.

     Section 9.10. Severability. In case one or more provisions of this Agreement or the other Loan Documents shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality, and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby.

     Section 9.11. Business Loans. Borrower warrants and represents that the Loans evidenced by the Notes are and shall be for business, commercial, investment, or other similar purposes and not primarily for personal, family, household, or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time to time in effect.

     Section 9.12. Governing Law; Submission to Jurisdiction. This Agreement, the Notes and the other Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect. Each Letter of Credit shall be governed by either the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600, or the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590 (and any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Lender). Borrower hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Houston, Texas in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, and Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court.
