Section 2.01 Commitment for Advances.

(a) Advances. Each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Advances to the Borrower from time to time on any Business Day during the period from the date of this Agreement until the Commitment Termination Date in an amount for each Lender not to exceed such Lender’s Unused Commitment Amount. 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, the Borrower may from time to time borrow, prepay, and reborrow Advances.

(b) Outstanding Advances under the Restated Agreement. Without any further action on the part of the Borrower or the Lenders, the parties hereto acknowledge and agree that, effective as of the date hereof, (i) all outstanding “Advances” which are “Eurodollar Rate Advances” under the Restated Agreement shall be automatically deemed to be outstanding as Eurodollar Rate Advances under this Agreement with the same Interest Period but adjusted for the Lenders’ pro rata share thereof based on the Lenders’ Commitments under this Agreement and (b) all outstanding “Advances” which are “Reference Rate Advances” under the Restated Agreement shall be automatically deemed to be outstanding as Reference Rate Advances under this Agreement but adjusted for the Lenders’ pro rata share thereof based on the Lenders’ Commitments under this Agreement. Such advances under the Restated Agreement shall be assigned, renewed, extended, and rearranged pursuant to the terms of this Agreement and the Notes and shall, for all purposes, be deemed a Borrowing hereunder. The Lenders shall make all appropriate adjustments and payments between and among themselves to account for the revised Pro Rata Shares resulting from the Lenders’ Commitments under this Agreement.

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

Section 2.02 Borrowing Base.

(a) Borrowing Base. The initial Borrowing Base in effect as of Effective Date has been set by the Administrative Agent and the Lenders and acknowledged by the Borrower as $90,000,000. Such initial Borrowing Base shall remain in effect until the next redetermination made pursuant to this Section 2.02. The Borrowing Base shall be determined in accordance with the standards set forth in Section 2.02(d) and is subject to periodic redetermination pursuant to Sections 2.02(b), 2.02(c) and 2.02(e).

(b) Calculation of Borrowing Base.

(i) The Borrower shall deliver to the Administrative Agent and each of the Lenders on or before August 1, 2010, and each August 31st thereafter, beginning with August 31, 2011, an Independent Engineering Report dated effective as of the immediately preceding June 30, and such other information as may be reasonably requested by any Lender with respect to the Oil and Gas Properties included or to be included in the Borrowing Base. Within 30 days after the Administrative Agent and the Lenders’ receipt of such Independent Engineering Report and other information, (A) the Administrative Agent shall deliver to each Lender the Administrative Agent’s recommendation for the redetermined Borrowing Base, (B) the Administrative Agent and the Lenders shall redetermine the Borrowing Base in accordance with Section 2.02(d), and (C) the Administrative Agent shall promptly notify the Borrower in writing of the amount of the Borrowing Base as so redetermined.

(ii) The Borrower shall deliver to the Administrative Agent and each Lender, on or before each February 28, beginning February 28, 2011, an Internal Engineering Report dated effective as of the immediately preceding December 31 and such other information as may be reasonably requested by the Administrative Agent or any Lender with respect to the Oil and Gas Properties included or to be included in the Borrowing Base. Within 30 days after the Administrative Agent and the Lenders’ receipt of such Internal Engineering Report and other information, (A) the Administrative Agent shall deliver to each Lender the Administrative Agent’s recommendation for the redetermined Borrowing Base, (B) the Administrative Agent and the Lenders shall redetermine the Borrowing Base in accordance with Section 2.02(d), and (C) the Administrative Agent shall promptly notify the Borrower in writing of the amount of the Borrowing Base as so redetermined.

(iii) In the event that the Borrower does not furnish to the 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, the 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 the Administrative Agent and the Lenders receive the relevant Independent Engineering Report, Internal Engineering Report, or other information, as applicable, whereupon the Administrative Agent and the Lenders shall redetermine the Borrowing Base as otherwise specified in this Section 2.02.

(iv) Each delivery of an Engineering Report by the Borrower to the Administrative Agent and the Lenders shall constitute a representation and warranty by the Borrower to the Administrative Agent and the Lenders that (A) the Borrower and its Subsidiaries, as applicable, own the Oil and Gas Properties specified therein with at least 80% (by value) of the Proven 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 and gas, and the xxxxx pertaining to such Oil and Gas Properties that are described therein as producing xxxxx (“Xxxxx”), were each producing oil and/or gas in paying quantities, except for Xxxxx that were utilized as water or gas injection xxxxx, carbon dioxide xxxxx or as water disposal xxxxx (each as noted in such Engineering Report), (C) the descriptions of quantum and nature of the record title interests of the Borrower and its Subsidiaries, as applicable, set forth in such Engineering Report include the entire record title interests of the Borrower and its Subsidiaries 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 the Borrower or any of its Subsidiaries in such Oil and Gas Properties except as set forth in Engineering Report, (E) no operating or other agreement to which the Borrower or any of its Subsidiaries is a party or by which the Borrower or any of its Subsidiaries is bound affecting any part of such Oil and Gas Properties requires the Borrower or any of its Subsidiaries to bear any of the costs relating to such Oil and Gas Properties greater than the record title interest of the Borrower or any of its Subsidiaries in such portion of the such Oil and Gas Properties except as set forth in such Engineering Report, except in the event the Borrower or any of its Subsidiaries is obligated under an operating agreement to assume a portion of a defaulting party’s share of costs, and (F) the Borrower’s and the Subsidiaries’ 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 the Borrower or the applicable Subsidiary 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 the Borrower or the applicable Subsidiary 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 xxxxx 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 2.02(b), (i) the Administrative Agent and the Lenders may, either in their sole discretion or at the request of the Borrower and based on such information as the Administrative Agent and the Lenders deem relevant (but in accordance with Section 2.02(d)), make one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations; (ii) the Administrative Agent and the Lenders may make additional redeterminations of the Borrowing Base in connection with any sale, lease, transfer, assignment, farm-out, conveyance, or other disposition of Oil and Gas Properties of the Borrower or any Subsidiary having a fair market value which, when taken together with (A) the fair market value of all other sales, leases, transfers, assignments, farm-outs, conveyances, or other dispositions of Oil and Gas Properties of the Borrower or any Subsidiary and (B) the Borrowing Base value attributed by the Administrative Agent to XX Xxxxxx that have been subject to novations, assignments, amendments, modifications 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; and (iii) the Administrative Agent and the Lenders, at the request of the Administrative Agent, may make additional redeterminations of the Borrowing Base in connection with any novation, assignment, modification, amendment or termination of a BB Hedge. 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. The party requesting the redetermination under this paragraph (c) shall give the other party at least 10 days’ prior written notice that a redetermination of the Borrowing Base pursuant to this paragraph (c) is to be performed; provided that, no such prior written notice shall be required for any redetermination made by the Lenders during the existence of a Default. In connection with any redetermination of the Borrowing Base under this Section 2.02(c), the Borrower shall provide the Administrative Agent and the Lenders with such information regarding the Borrower and its Subsidiaries’ business (including, without limitation, its Oil and Gas Properties, the Proven Reserves, and production relating thereto) as the Administrative Agent or any Lender may reasonably request; provided that, (y) in the case of requests for an increase to the Borrowing Base of $5,000,000 or more, the request of an updated Independent Engineering Report is deemed to be reasonable and (z) other than as provided in the preceding clause (y), no new reserve or deliverability studies shall be required with respect to existing Oil and Gas Properties evaluated in the most recently delivered Engineering Report upon which the then

effective Borrowing Base was determined. The Administrative Agent shall promptly notify the Borrower in writing of each redetermination of the Borrowing Base pursuant to this Section 2.02(c) and the amount of the Borrowing Base as so redetermined.

(d) Standards for Redetermination. Each redetermination of the Borrowing Base by the Administrative Agent and the Lenders pursuant to this Section 2.02 shall be made (i) in the sole discretion of the Administrative Agent and the Lenders (but in accordance with the other provisions of this Section 2.02(d)), (ii) in accordance with the 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 the Administrative Agent and the Lenders relating to the Proven Reserves of the Borrower and its Subsidiaries, and (iv) based upon the estimated value of the Proven Reserves owned by the Borrower and its Subsidiaries as determined by the Administrative Agent and the Lenders. In valuing and redetermining the Borrowing Base, the Administrative Agent and the Lenders may also consider the business, financial condition, and Debt obligations of the Borrower and its Subsidiaries and such other factors as the Administrative Agent and the Lenders customarily deem appropriate. In that regard, the 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 the Administrative Agent and the Lenders. No Proven Reserves shall be included or considered for inclusion in the Borrowing Base unless the Administrative Agent shall have received, at the Borrower’s expense, (A) evidence of title reasonably satisfactory in form and substance to the Administrative Agent covering at least 80% (by value) of the Proven Reserves and the Oil and Gas Properties relating thereto and at least 80% (by value) of the Proven Reserves categorized as “proved, developed and producing” and the Oil and Gas Properties related thereto and (B) Mortgages and such other Security Instruments requested by the Administrative Agent to the extent necessary to cause the Administrative Agent to have an Acceptable Security Interest in at least 80% (by value) of the Proven Reserves and the Oil and Gas Properties relating thereto. At all times after the Administrative Agent has given the Borrower notification of a redetermination of the Borrowing Base under this Section 2.02, the Borrowing Base shall be equal to the redetermined amount or such lesser amount designated by the Borrower and disclosed in writing to the Administrative Agent and the Lenders until the Borrowing Base is subsequently redetermined in accordance with this Section 2.02.

Section 2.03 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. (Dallas, Texas time) / 9:00 a.m. (Los Angeles, California 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) on the Business Day of the proposed Borrowing, in the case of a Borrowing comprised of Reference Rate Advances, by the Borrower to the Administrative Agent, which shall in turn give to each Lender prompt notice of such proposed Borrowing by telecopier or telex. Each Notice of a Borrowing shall be given by telecopier or telex, confirmed immediately in writing, specifying the information required therein. In the case of a proposed Borrowing comprised of Eurodollar Rate Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.09(b). Each Lender shall, before 1:00 pm (Dallas, Texas time) / 11:00 a.m. (Los Angeles, California time) on the date of such Borrowing, make available for the account of its Lending Office to the Administrative Agent at its address referred to in Section 9.02, or such other location as the 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 the Administrative Agent’s receipt of

such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent shall make such funds available to the Borrower at its account with the Administrative Agent.

(b) Conversions and Continuations. The Borrower may elect to Convert or continue any Borrowing under this Section 2.03 by delivering an irrevocable Notice of Conversion or Continuation to the Administrative Agent at the Administrative Agent’s office no later than 11:00 a.m. (Dallas, Texas time) / 9:00 a.m. (Los Angeles, California 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) on the Business Day of 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 telex or telecopier confirmed immediately in writing specifying the information required therein. Promptly after receipt of a Notice of Conversion or Continuation under this Section, the 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 2.09(b).

(i) at no time shall there be more than six Interest Periods applicable to outstanding Eurodollar Rate Advances and the 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 the 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 the Borrower to select Eurodollar Rate Advances from such Lender shall be suspended until such Lender shall notify the 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 the Administrative Agent is unable to determine the Eurodollar Rate for Eurodollar Rate Advances comprising any requested Borrowing, the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the 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 Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the 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 the Borrower to select Eurodollar Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the 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 the 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 Section 1.01 and paragraph (b) above, the Administrative Agent shall forthwith so notify the Borrower and the Lenders and such Advances shall be made available to the 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 the Borrower. In the case of any Borrowing for which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the 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 the 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 the Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender shall not make available to the Administrative Agent such Lender’s Pro Rata Share of a Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.03 and the Administrative Agent may, in reliance upon such assumption, make available to the 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 the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the 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 the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the 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 the 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 2.04 Reduction of the Commitments.

(a) The Borrower shall have the right, upon at least three Business Days’ irrevocable notice to the 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 $500,000 or in integral multiples of $100,000 in excess thereof.

(b) Other than as provided in Section 2.04(c) below, any reduction and termination of the Commitments pursuant to this Section 2.04 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, the Borrower, at the Borrower’s election may (with the consent of the Administrative Agent) elect to terminate such Defaulting Lender’s Commitment

hereunder; provided that (i) such termination must be of the Defaulting Lender’s entire Commitment, (ii) the Borrower shall pay all amounts owed by the 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 2.12 as result of such payment of Advances) and shall deposit with the 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, (iii) a Defaulting Lender’s Commitment may be terminated by the Borrower under this Section 2.04(c) if and only if at such time, the 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 the Borrower’s election to terminate a Defaulting Lender’s Commitment pursuant to this clause (c) and the payment and deposit of amounts required to be made by the Borrower under clause (ii) above, (A) such Defaulting Lender shall cease to be a “Lender” hereunder for all purposes except that such Lender’s rights under Sections 2.13, 2.14, and 9.07 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.

Section 2.05 Prepayment of Advances.

(a) Optional. The Borrower may prepay the Advances, after giving by 11:00 a.m. (Dallas, Texas time) / 9:00 a.m. (Los Angeles, California 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 the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the 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 2.12 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 clause (ii) below, if the aggregate outstanding amount of the Advances plus the Letter of Credit Exposure ever exceeds the lesser of the (y) Borrowing Base and (z) the aggregate Commitments, the Borrower shall, after receipt of written notice from the Administrative Agent regarding such deficiency, take any of the following actions (and the failure of the Borrower to take such actions to remedy such Borrowing Base deficiency shall constitute an Event of Default):

(A) prepay Advances or, if the 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 10 Business Days after the date such deficiency notice is received by the Borrower from the Administrative Agent;

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

(C) (i) deliver, within 10 Business Days after the date such deficiency notice is received by the Borrower from the Administrative Agent, written notice to the Administrative Agent indicating the Borrower’s election to repay the 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 the Borrower from the Administrative Agent and each following installment due 30 days after the preceding installment and (ii) make such payments and deposits within such time periods; provided that, the Borrowing Base deficiency cure permitted under this clause (C) shall not be available to the Borrower unless, concurrent with the written notice delivered to the Administrative Agent electing this option, the Borrower shall have delivered to the Administrative Agent a calculation of the Borrower’s consolidated cash flow forecast and financial projections which demonstrates, to the Administrative Agent’s satisfaction, the Borrower’s ability to make each such installment payments and to otherwise pay its other Debt and trade accounts payable as they become due; or

(D) (i) deliver, within 10 Business Days after the date such deficiency notice is received by the Borrower from the Administrative Agent, written notice to the Administrative Agent indicating the Borrower’s election to combine the options provided in clause (B) and clause (C) above, and also indicating the amount to be prepaid in installments and the amount to be provided as additional Collateral, and (ii) make such five equal consecutive monthly installments and deliver such additional Collateral within the time required under clause (B) and clause (C) above.

(ii) Upon each reduction of the Borrowing Base, if any, resulting from a Borrowing Base redetermination made under Section 2.02(c)(ii) or (iii), if the aggregate outstanding amount of the Advances plus the Letter of Credit Exposure exceeds the lesser of the (y) Borrowing Base and (z) the aggregate Commitments, then the Borrower shall immediately prepay the Advances or, if the 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 2.05(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 2.12 as a result of such prepayment being made on such date. Each prepayment under this Section 2.05(b) shall be applied to the Advances as determined by the Administrative Agent and agreed to by the Lenders in their sole discretion. The failure of the Borrower to provide a notice of its election within the required 10 days as required in clause (i) above shall be deemed to be an election by the Borrower to take the actions provided in clause (i)(A) above.

(c) Reduction of Commitments. On the date of each reduction of the aggregate Commitments pursuant to Section 2.04, the Borrower agrees to make a prepayment in respect of the outstanding amount of the Advances to the extent, if any, that the aggregate unpaid principal amount of all Advances plus the Letter of Credit Exposure exceeds the lesser of (A) the aggregate Commitments, as

so reduced and (B) the Borrowing Base. Each prepayment pursuant to this Section 2.05(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 2.12 as a result of such prepayment being made on such date. Each prepayment under this Section 2.05(c) shall be applied to the Advances as determined by the Administrative Agent and agreed to by the Lenders in their sole discretion; provided that, outstanding Reference Rate Advances, if any, shall be paid in full first before any such prepayments are applied to outstanding Eurodollar Rate Advances.

(d) Illegality. If any Lender shall notify the Administrative Agent and the Borrower 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 maintain any Eurodollar Rate Advances of such Lender then outstanding hereunder, (i) the Borrower shall, no later than 11:00 a.m. (Dallas, Texas time) / 9:00 a.m. (Los Angeles, California 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, prepay all of the Eurodollar Rate Advances made by such Lender then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment being made on such date, (ii) such Lender shall simultaneously make a Reference Rate Advance to the 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 the 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 the Administrative Agent that the circumstances causing such suspension no longer exist.

(e) No Additional Right; Ratable Prepayment. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in Section 2.04(c) and in this Section 2.05, and all notices given pursuant to this Section 2.05 shall be irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this Section 2.05 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 2.06 Repayment of Advances. The Borrower shall repay to the Administrative Agent for the ratable benefit of the Lenders the outstanding principal amount of each Advance, together with any accrued interest thereon, on the Maturity Date or such earlier date pursuant to Section 7.02 or Section 7.03.

Section 2.07 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 the 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 the 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 clause (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 and (B) 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 the 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 xxxxx xxxxx 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 2.07(d) exists or any Lender is at such time a Defaulting Lender hereunder, unless the Issuing Lender has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the Issuing Lender’s risk with respect to such Lender.

(b) Participations. Upon (i) the date of the issuance or increase of a Letter of Credit, and (ii) the Effective Date as to the deemed issuance of the Existing Letters of Credit under Section 2.07(i), 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 telecopy 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. (Dallas, Texas time) / 9:00 a.m. (Los Angeles, California

time) on the fifth Business Day before the date of the proposed issuance, increase, or extension of the Letter of Credit, and the Issuing Lender shall give to each other Lender prompt notice thereof by telex, telephone, or telecopy. 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, the 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 such Letter of Credit for the account of the Borrower. Each Letter of Credit Application shall be irrevocable and binding on the Borrower.

(d) Reimbursement. The Borrower hereby agrees to pay on demand to the Issuing Lender an amount equal to any amount paid by the Issuing Lender under any 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 promptly reimbursed by the Borrower upon demand, the Issuing Lender shall give the Administrative Agent notice of the Borrower’s failure to make such reimbursement and the Administrative Agent shall promptly notify each Lender having a Commitment of the amount necessary to reimburse the Issuing Lender. Upon such notice from the 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 the Borrower transferred at the Borrower’s request to the Issuing Lender. If such reimbursement is not made by any Lender to the Issuing Lender on the same day on which the 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. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat such reimbursements to the Issuing Lender as Reference Rate Advances under a Borrowing requested by the Borrower to reimburse the Issuing Lender which have been transferred to the Issuing Lender at the Borrower’s request.

(e) Obligations Unconditional. The obligations of the 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 the 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 the Borrower in connection with the Letters of Credit or the Borrower’s rights under Section 2.07(f) below.

(f) Liability of Issuing Lender. The 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 the Borrower shall have a claim against the Issuing Lender, and the Issuing Lender shall be liable to the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves 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 the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.04(c), 2.05(b), 7.02(b), or 7.03(b), then the Borrower and the Issuing Lender shall establish the Cash Collateral Account and the 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. The 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, (A) the Issuing Lender may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Issuing Lender shall release to the Borrower at the 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 any order determined by the Issuing Lender, regardless of any Letter of Credit Exposure that may remain outstanding. The Issuing Lender may in its sole discretion at any time release to the Borrower any funds held in the Cash Collateral Account.

(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, the 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.

(i) Existing Letters of Credit. The Issuing Lender, the Lenders and the Borrower agree that effective as of the Effective Date, the Existing Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement.

Section 2.08 Fees.

(a) Commitment Fees. The Borrower agrees to pay to the 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 June 30, 2010 and continuing thereafter through and including the Commitment Termination Date.

(b) Letter of Credit Fees.

(i) The Borrower agrees to pay to the Administrative Agent for the pro rata benefit of the Lenders a per annum letter of credit fee for each Letter of Credit issued hereunder in an amount equal to the greater of (A) the Applicable Margin then in effect for Eurodollar Rate Advances times the daily maximum amount available to be drawn under such Letter of Credit and (B) $1,000, payable quarterly in arrears on the last day of each March, June, September, and December commencing on June 30, 2010 and continuing thereafter through and including the Commitment Termination Date.

(ii) The 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.

Section 2.09 Interest. The 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 March, June, September, and December commencing on June 30, 2010 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 and, in the case of six month Interest Periods, on the day which occurs during such Interest Period three months from the first day of such Interest Period.

(d) 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 2.09 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, the 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 THE 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 THE BORROWER.

Section 2.10 Payments and Computations.

(a) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes not later than 11:00 a.m. (Dallas, Texas time) / 9:00 a.m. (Los Angeles, California time) on the day when due in Dollars to the Administrative Agent at the location referred to in the Notes (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds without deduction, setoff, or counterclaim of any kind, except as may be applicable to any Defaulting Lender. The 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 the Administrative Agent, the Issuing Lender, or a specific Lender pursuant to Section 2.08(c), 2.09(c), 2.09(d), 2.12, 2.13, 2.14, 8.05, or 9.07, but after taking into account payments effected pursuant to Section 9.04) in accordance with each Lender’s Pro Rata Share to the 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 the 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 the 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 the 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 next preceding Business Day.

(d) Administrative Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower prior to the date on which any payment is due to the Lenders that the Borrower shall not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the 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 the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the 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 the Administrative Agent, at the Federal Funds Rate for such day.

Section 2.11 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 the Lenders (other than as a result of a termination of a Defaulting Lender’s Commitment under Section 2.04(c)), such Lender shall notify the 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. The Borrower agrees that any Lender so purchasing a participation from another

Lender pursuant to this Section 2.11 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 the Borrower in the amount of such participation. If a Lender fails to make an Advance with respect to a Borrowing as and when required hereunder and the 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 the Lenders in accordance with their Pro Rata Share.

Section 2.12 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 2.05, the acceleration of the maturity of the Notes pursuant to Article VII, or otherwise, or (b) the 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, the Borrower shall, within 10 days of any written demand sent by any Lender to the Borrower through the Administrative Agent, pay to the 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 2.13 Increased Costs.

(a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding, or maintaining Eurodollar Rate Advances, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

(b) Capital Adequacy. If any Lender or the Issuing Lender determines in good faith that compliance with any law or regulation adopted or changed after the date hereof or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or the Issuing Lender or any corporation controlling such Lender or the Issuing Lender and that the amount of such capital is increased by or based upon the existence of such Lender’s commitment to lend or the Issuing Lender’s commitment to issue the Letters of Credit and other commitments of this type, then, upon 30 days’ prior written notice by such Lender or the Issuing Lender (with a copy of any such demand to the Administrative Agent), the Borrower shall immediately pay to the Administrative Agent for the account of such Lender or to the Issuing Lender, as the case may be, from time to time as specified by such Lender or the Issuing Lender, additional amounts sufficient to compensate such Lender or the Issuing Lender, in light of such circumstances, (i) with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s commitment to lend under this Agreement and (ii) with respect to the Issuing Lender, to the extent that the Issuing Lender reasonably determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit. A certificate as to such amounts and detailing the calculation of

such amounts submitted to the Borrower by such Lender or the Issuing Lender shall be conclusive and binding for all purposes, absent manifest error.

(c) Letters of Credit. If any change adopted after the date hereof in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) 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 (ii) 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, the 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. A certificate as to such increased cost incurred by the Issuing Lender, as a result of any event mentioned in clause (i) or (ii) above, and detailing the calculation of such increased costs submitted by the Issuing Lender to the Borrower, shall be conclusive and binding for all purposes, absent manifest error.

(d) Mitigation. If any Lender requests compensation under Section 2.13, or requires the Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, 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 2.13 or 2.14, 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. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(e) Delay in Requests. Failure or delay on the part of any Lender or the Issuing Lender to demand compensation pursuant to this Section 2.13 shall not constitute a waiver of such Lender’s or the Issuing Lender’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the Issuing Lender pursuant to this Section 2.13 for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or the Issuing Lender, as the case may be, notifies the 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 nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 2.14 Taxes.

(a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.10, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the Issuing Lender, and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such Lender, the Issuing Lender, or the Administrative Agent (as the case may be) is organized or any political subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”) and, in the case of each Lender and the Issuing Lender, Taxes by the jurisdiction of such Lender’s Lending Office or any political subdivision

of such jurisdiction. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Lender, the Issuing Lender, or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14), such Lender, the Issuing Lender, or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; provided, however, that if the Borrower’s obligation to deduct or withhold Taxes is caused solely by such Lender’s, the Issuing Lender’s, or the Administrative Agent’s failure to provide the forms described in paragraph (d) of this Section 2.14 and such Lender, the Issuing Lender, or the Administrative Agent could have provided such forms, no such increase shall be required; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) Other Taxes. In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Loan Documents (hereinafter referred to as “Other Taxes”).

(c) Indemnification. THE BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.14) PAID BY SUCH LENDER, THE ISSUING LENDER, OR THE ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED. EACH PAYMENT REQUIRED TO BE MADE BY THE BORROWER IN RESPECT OF THIS INDEMNIFICATION SHALL BE MADE TO THE ADMINISTRATIVE AGENT FOR THE BENEFIT OF ANY PARTY CLAIMING SUCH INDEMNIFICATION WITHIN 30 DAYS FROM THE DATE THE BORROWER RECEIVES WRITTEN DEMAND THEREFOR FROM THE ADMINISTRATIVE AGENT ON BEHALF OF ITSELF AS ADMINISTRATIVE AGENT, THE ISSUING LENDER, OR ANY SUCH LENDER. IF ANY LENDER, THE ADMINISTRATIVE AGENT, OR THE ISSUING LENDER RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID BY THE BORROWER UNDER THIS PARAGRAPH (C), SUCH LENDER, THE ADMINISTRATIVE AGENT, OR THE ISSUING LENDER, AS THE CASE MAY BE, SHALL PROMPTLY PAY TO THE BORROWER THE BORROWER’S SHARE OF SUCH REFUND.

(d) Foreign Lender Withholding Exemption. Each Lender and Issuing Lender that is not incorporated under the laws of the United States of America or a state thereof agrees that it shall deliver to the Borrower and the Administrative Agent (i) two duly completed copies of United States Internal Revenue Service Form W8-ECI or W8-BEN or successor applicable form, as the case may be, certifying in each case that such Lender is entitled to receive payments under this Agreement and the Notes payable to it, without deduction or withholding of any United States federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the case may be, to establish an exemption from United States backup withholding tax, and (iii) any other governmental forms which are necessary or required under an applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax, which have been reasonably requested by the Borrower. Each Lender which delivers to the Borrower and the Administrative Agent a Form W8-ECI or W8-BEN and Form W-8 or W-9 pursuant to the next preceding sentence further undertakes to deliver to the Borrower and the Administrative Agent two further copies of the said letter and Form W8-ECI or W8-BEN and Form W-8 or W-9 , or successor applicable forms, or other manner of certification, as the case may be, on or before the date that any such

letter or form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent letter and form previously delivered by it to the Borrower and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the Borrower and the Administrative Agent certifying in the case of a Form W8-ECI or W8-BEN that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Lender from duly completing and delivering any such letter or form with respect to it and such Lender advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and in the case of a Form W-8 or W-9, establishing an exemption from United States backup withholding tax, such Lender shall not be required to deliver such letter or forms. The Borrower shall withhold tax at the rate and in the manner required by the laws of the United States with respect to payments made to a Lender failing to timely provide the requisite Internal Revenue Service forms.

Section 2.15 Replacement of Lender. If (i) any Lender requests compensation under Section 2.13(a) or (b), (ii) any Lender suspends its obligation to continue, or Convert Advances into, Eurodollar Rate Advances pursuant to Section 2.03(c)(ii) or Section 2.11, (iii) any Lender becomes a Defaulting Lender, or (iv) any Lender is a Non-Consenting Lender (any such Lender, a “Subject Lender”), then (A) in the case of a Defaulting Lender, the Administrative Agent may, upon notice to the Subject Lender and the 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 9.06), 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 (B) in the case of any Subject Lender, including a Defaulting Lender, the Borrower may, upon notice to the Subject Lender and the Administrative Agent and at the 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 9.06), 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 the Borrower, the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 9.06;

(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 2.12) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(C) in the case of any such assignment resulting from a claim for compensation under Section 2.13, 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 the 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 2.15 and to the extent permitted under applicable Legal Requirements, each Lender hereby designates and appoints the 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 the Borrower or the Administrative Agent replacing a Defaulting Lender as provided in this Section 2.15, the Borrower may terminate such Defaulting Lender’s Commitment as provided in Section 2.04.

Section 4.10 Reserved.

Section 4.11 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 the 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 the 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 4.11 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 4.11 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 4.12 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 by more than $1,000,000 in the aggregate. Neither the 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 the

Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the 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, the Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower or any member of the Controlled Group for post-retirement benefits to be provided to the current and former employees of the 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 4.13 Condition of Property; Casualties. Each of the Borrower and the Guarantors has good and marketable title to 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 the Borrower and the Guarantors has good and indefeasible title to 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 the Borrower and each of the Guarantors are in good repair, working order and condition, normal wear and tear excepted. Since the date of the Financial Statements and except as otherwise disclosed by the Borrower to the Administrative Agent in writing, neither the business nor the material Properties of the 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 4.14 No Burdensome Restrictions; No Defaults.

(a) Other than those identified on Schedule 4.14(a), neither the 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. Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any contract, agreement, lease, or other instrument to which the Borrower or any Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Change. Neither the Borrower nor any of its Subsidiaries has received any notice of default under any material contract, agreement, lease, or other instrument to which the Borrower or such Subsidiary is a party a copy of which has not been delivered to the Administrative Agent.

(b) No Default has occurred and is continuing.

(c) Certain Actions. Without limiting the foregoing, (i) all necessary notices have been properly filed, and no further action is required under current Environmental Law as to each Response or other restoration or remedial project undertaken by the Borrower or the Guarantors or any of their former Subsidiaries on any of their presently or formerly owned or operated Property and (ii) the present and, to the Borrower’s best knowledge, future liability, if any, of the Borrower and the Guarantors which could reasonably be expected to arise in connection with requirements under Environmental Laws will not result in a Material Adverse Change.

The Administrative Agent, the Issuing Lender and each Lender agrees to promptly notify the Borrower after any such set-off and application made by the Administrative Agent, the Issuing Lender or such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application.

ARTICLE VIII

THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER

Section 8.01 Authorization and Action. Each Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof and of the other Loan Documents, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement or any other Loan Document (including, without limitation, enforcement or collection of the Notes), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, any other Loan Document, or applicable law.

Section 8.02 Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or omitted to be taken (INCLUDING THE ADMINISTRATIVE AGENT’S OWN NEGLIGENCE) by it or them under or in connection with this Agreement or the other Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Note as the holder thereof until the Administrative Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Administrative Agent; (b) may consult with legal counsel (including counsel for the 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; (c) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties, or representations made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or any other Loan Document on the part of the Borrower or its Subsidiaries or to inspect the Property (including the books and records) of the Borrower or its Subsidiaries; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency, or value of this Agreement or any other Loan Document; and (f) shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon any notice, consent, certificate, or other instrument or writing (which may be by telecopier or telex) believed by it to be genuine and signed or sent by the proper party or parties.

Section 8.03 The Administrative Agent and Its Affiliates. With respect to its Commitment, the Advances made by it and the Notes issued to it, the 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 the Administrative Agent. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. The 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, the Borrower or any of its Subsidiaries, and any Person who may do business with or own securities of the Borrower or any such Subsidiary, all as if the Administrative Agent were not an agent hereunder and without any duty to account therefor to the Lenders.

Section 8.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the 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 the 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 8.05 Indemnification. THE LENDERS SEVERALLY AGREE TO INDEMNIFY THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS (TO THE EXTENT NOT REIMBURSED BY THE 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 THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY ACTION TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT OR THE ISSUING LENDER UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (INCLUDING THE ADMINISTRATIVE AGENT’S AND THE ISSUING LENDER’S OWN NEGLIGENCE), AND INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LIABILITIES, 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 THE ADMINISTRATIVE AGENT’S OR THE ISSUING LENDER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER PROMPTLY UPON DEMAND FOR ITS RATABLE SHARE OF ANY OUT-OF-POCKET EXPENSES (INCLUDING COUNSEL FEES) INCURRED BY THE 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 THE ADMINISTRATIVE AGENT OR THE ISSUING LENDER IS NOT REIMBURSED FOR SUCH BY THE BORROWER. To the extent that the indemnity obligations provided in this Section 8.05 are for the benefit of the 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 8.05 until such time as such Obligations have been satisfied or terminated in full and subject to the terms of the last sentence of Section 9.09. In such event, in determining the pro rata shares under this Section 8.05, the Lenders shall include the aggregate amount (giving effect to any netting agreements) that would be owing to such Swap Counterparty if such Hedge Contracts were terminated at the time of determination.

Section 8.06 Successor Administrative Agent and Issuing Lender. The Administrative Agent or the Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Majority Lenders upon receipt of written notice from the Majority Lenders to such effect. Upon receipt of notice of any such resignation or removal, the Majority 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 the Borrower, which consent shall not be unreasonably withheld. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Majority Lenders with the consent of the 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 Majority Lenders’ removal of the retiring Administrative Agent or Issuing Lender, then the retiring Administrative Agent or Issuing Lender may, on behalf of the Lenders and the 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 the Administrative Agent or Issuing Lender shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that (A) in the case of any collateral security held by the Administrative Agent on behalf of the 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 (B) 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 (2) 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 Majority 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 8.07 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 Majority Lenders as set forth in Section 7.02 or Section 7.03 above) 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 the 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 the Administrative Agent and the Issuing Lender have been made), termination of all Hedge Contracts with Swap Counterparties that are secured by the Liens on the Collateral (other than Hedge Contracts with any Swap Counterparty with respect to which other arrangements satisfactory to the Swap Counterparty and the Borrower have been made; provided that, unless a Swap Counterparty notifies the 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), and payment in full of all Obligations (other than Obligations arising under Hedge Contracts with any Swap Counterparty with respect to which other arrangements satisfactory to the Swap Counterparty and the Borrower have been made; provided that, unless a Swap Counterparty notifies the 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); (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 the Borrower or any Subsidiary owned no interest at the time the Lien was granted or at any time thereafter; (iv) constituting Property leased to the Borrower or any Subsidiary 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 the Borrower or such Subsidiary to be, renewed or extended; or (v) if approved, authorized or ratified in writing by the applicable Majority Lenders or all the Lenders, as the case may be, as required by Section 9.01. Upon the request of the Administrative Agent at any time, the Secured Parties will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 8.07. 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, the Borrower, the 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, each Secured Party not party hereto hereby agrees to the terms of this paragraph (c).
