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) and 2.02(c) and is subject to mandatory reductions pursuant to Section 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 May 1, 2010, an Independent Engineering Report dated effective as of the immediately preceding January 1, and, in any case, 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. On or before June 1, 2010, and based on 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 Required Lenders shall redetermine the Borrowing Base in accordance with Section 2.02(d) (except that any increase in the Borrowing Base shall require the consent of all the Lenders), and (C) the Administrative Agent shall promptly notify the Borrower in writing of the amount of the Borrowing Base as so redetermined. The Borrower shall deliver to the Administrative Agent and each of the Lenders on or before each April 1, beginning April 1, 2011, an Independent Engineering Report dated effective as of the immediately preceding January 1, and, in any case, 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 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 Required Lenders shall redetermine the Borrowing Base in accordance with Section 2.02(d) (except that any increase in the Borrowing Base shall require the consent of all the Lenders), 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 October 1, beginning October 1, 2010, an Internal Engineering Report dated effective as of the immediately preceding July 1, 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 Required Lenders shall redetermine the Borrowing Base in accordance with Section 2.02(d) (except that any increase in the Borrowing Base shall require the consent of all the Lenders), 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 Required Lenders (except that any increase in the Borrowing Base shall require the consent of all 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 Required Lenders (except that any increase in the Borrowing Base shall require the consent of all 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 Restricted Subsidiaries, as applicable, own the Oil and Gas Properties specified therein with at least 85% (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, the PDP Reserves identified therein were developed for Hydrocarbons, and the ▇▇▇▇▇ pertaining to such Oil and Gas Properties that are described therein as producing ▇▇▇▇▇ ("▇▇▇▇▇"), were each producing Hydrocarbons in paying quantities, except for ▇▇▇▇▇ that were utilized as water or gas injection ▇▇▇▇▇ or as water disposal ▇▇▇▇▇, (C) the descriptions of quantum and nature of the record title interests of the Borrower and its Restricted Subsidiaries, as applicable, set forth in such Engineering Report include the entire record title interests of the Borrower and its Restricted 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 Restricted Subsidiaries is a party or by which the Borrower or any of its Restricted Subsidiaries is bound affecting any part of such Oil and Gas Properties requires the Borrower or any of its Restricted 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 Restricted Subsidiaries in such portion of the such Oil and Gas Properties as set forth in such Engineering Report, except in the event the Borrower or any of its Restricted 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 Restricted 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 Restricted 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 Restricted 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 ▇▇▇▇▇ identified in such Engineering Report or identified in the exhibits to the Mortgages encumbering such Oil and Gas Properties.

(v) Concurrently with each delivery of an Engineering Report, the Borrower shall deliver to the Administrative Agent a First Lien Cap Certificate. The First Lien Cap Certificate required under this clause (v) shall no longer be required once the Second Lien Debt Payoff has occurred

(c) Interim Redeterminations. In addition to the Borrowing Base redeterminations provided for in Section 2.02(b) and based on such information as the Administrative Agent and the Lenders deem relevant (but in accordance with Section 2.02(d)):

(i) at the election of the Required Lenders, the Administrative Agent and the Lenders may make one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations; and

(ii) at the request of the Borrower, the Administrative Agent and the Lenders may make one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations.

(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 Restricted Subsidiaries, and (iv) based upon the estimated value of the Proven Reserves owned by the Borrower and its Restricted 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 Restricted Subsidiaries and such other factors as the Administrative Agent and the Lenders customarily deem appropriate, including without limitation, commodity price assumptions, projections of production, operating expenses, general and administrative expenses, capital costs, working capital requirements, liquidity evaluations, dividend payments, environmental costs, and legal costs. In that regard, the Borrower acknowledges that the determination of the Borrowing Base contains a value 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 (or in the case of the initial Borrowing Base set on the Effective Date, at least 70% (by value) of the Proven Reserves 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 85% (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 (i) to the redetermined amount or (ii) such lesser amount designated by the Borrower and disclosed in writing to the Administrative Agent and the Lenders, provided that the Borrower shall not request that the Borrowing Base be reduced to a level that would result in a Borrowing Base Deficiency, until the Borrowing Base is subsequently redetermined in accordance with this Section 2.02.

(e) Mandatory Reductions in the Borrowing Base. In addition to the Borrowing Base redeterminations provided for otherwise in this Section 2.02, the Borrowing Base shall be automatically reduced as follows:

(i) Effective immediately upon each issuance of Senior Unsecured Notes by the Borrower or any Restricted Subsidiary, the Borrowing Base shall automatically reduce on the

effective date of such issuance by an amount equal to 25% of (A) the principal amount of such Senior Unsecured Notes minus (B) to the extent such Senior Unsecured Notes constitute Refinancing Debt, the principal amount of Second Lien Debt or other Senior Unsecured Notes being refinanced thereby.

(ii) Effective immediately upon the issuance of any Additional Subordinated Debt (other than Senior Unsecured Notes) by the Borrower or any Restricted Subsidiary, the Borrowing Base shall automatically reduce on the effective date of such issuance by an amount equal to 25% of (A) the principal amount of such Additional Subordinated Debt minus (B) the principal amount of Second Lien Debt repaid with the proceeds of such Additional Subordinated Debt (other than repayments of any increases in principal of Second Lien Debt effected after the Amendment No. 11 Effective Date and any interest accrued on such increased principal amount).

(iii) Effective immediately upon the occurrence of a Triggering Event, the Borrowing Base shall automatically reduce on the date such Triggering Event is effected by an amount equal to (A) in the case of a Disposition of Oil and Gas Properties, the value, if any, assigned such Oil and Gas Properties under the then effective Borrowing Base, as reasonably determined by the Administrative Agent, and (B) in the case of a hedge position or Hedge Contract that has been novated, assigned, unwound, terminated, or amended, the value, if any, assigned such hedge position or Hedge Contract under the then effective Borrowing Base, as reasonably determined by the Administrative Agent.

(iv) Effective immediately upon each incurrence of Second Lien Accordion Debt, the Borrowing Base shall automatically reduce on the date on which such incurrence occurs, by an amount equal to 25% of the principal amount of such Second Lien Accordion Debt.

(v) If (A) the Borrowing Base has not been redetermined within 75 days after receipt by the Administrative Agent of the First Lien Cap Certificate required under Section 2.02(b)(v) above and the related Engineering Reports and (B) the Borrowing Base then in effect is greater than the First Lien Cap (as defined in the Intercreditor Agreement and as set forth in such First Lien Cap Certificate) then in effect, then effective as of the 76th day following such receipt, the Borrowing Base shall automatically be reduced to equal such First Lien Cap and such First Lien Cap shall be in effect until redetermined as provided in the Intercreditor Agreement.

For the avoidance of doubt, the automatic reductions of the Borrowing Base provided for in this Section 2.02 shall not constitute nor be construed as a consent to any Debt incurrence or proposed Debt incurrence that would not be permitted under the terms of this Agreement.

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) (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. Each Notice of a Borrowing shall be given in writing, including by telecopier, 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(a)(ii). Each Lender shall, before 11:00 a.m. (Dallas, Texas time) on the date of such Borrowing, make available for the account of its applicable 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) (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 telephone notice promptly 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(a)(ii).

(i) at no time shall there be more than four 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 applicable 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 Required 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 existing Eurodollar Rate Advances, 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 any Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent (the "Non-Funding Lender"), such Non-Funding 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 Non-Funding Lender, the Federal Funds Rate for such day. If such Non-Funding Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Non-Funding 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 Non-Funding 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' notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitment; provided that each partial reduction shall be in the aggregate amount of $3,000,000 or in integral multiples of $1,000,000 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 elect to terminate such Defaulting Lender's Commitment hereunder; provided that (i) such termination must be of the Defaulting Lender's entire Commitment, (ii) subject to the set-off rights set forth in the immediately following sentence, 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, including any such Letter of Credit Exposure that has been reallocated pursuant to Section 2.17(c)(i); (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. With respect to the amounts described in clause (ii) above which would be payable by the Borrower to the Defaulting Lender (but not including any deposits that the Borrower is required to make with respect to the Letter of Credit Exposure), the Borrower may set-off and apply any amounts owing from such Defaulting Lender or Affiliate thereof to the Borrower under any Hedge Contract against any such amounts payable to the Defaulting Lender. 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, provided that, any such termination will not be deemed to be a waiver or release of any claim by Borrower, the Administrative Agent or any Lender may have against such Defaulting Lender.

Section 2.05 Prepayment of Advances.

(a) Optional. The Borrower may prepay the Advances, after giving by 10:00 a.m. (Dallas, Texas time) (i) in the case of Eurodollar Rate Advances, at least three Business Days' or (ii) in the case of Reference Rate Advances, same Business Day's, irrevocable prior written notice (or irrevocable telephone notice promptly confirmed in writing) 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 amounts prepaid in respect of Reference Rate Advances shall be made in a minimum amount of $1,000,000 and in integral multiples of $500,000 in excess thereof, and (C) any prepayments made in respect of Borrowings comprised of Eurodollar Rate Advances shall be made in a minimum amount of $3,000,000 and in integral multiples of $1,000,000 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 Borrowings of at least $1,000,000. Full prepayments of any Borrowing are permitted without restriction of amounts.

(b) Borrowing Base Deficiencies.

(i) Other than as provided in clause (ii) and clause (iii) below and in Section 5.11, if a Borrowing Base Deficiency exists, then 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 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, such that the Borrowing Base Deficiency is cured within 10 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 the Required Lenders such that the applicable Borrowing Base Deficiency is cured within 10 days after the date of such notice by the Administrative Agent is received;

(C) (1) deliver within 10 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 (2) to make such payments and deposits within such time period; or

(D) (1) deliver within 10 days after the date such deficiency notice is received by the Borrower to 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 (2) make such five equal consecutive monthly installments and deliver such additional Collateral within the time required under clause (B) and clause (C) above.

The failure of the Borrower to deliver an election notice pursuant to the terms of this clause (b)(i) shall be deemed to be an election by the Borrower of the option set forth in clause (C) above.

(ii) Upon each reduction of the Borrowing Base under Section 2.02(e)(i) or (ii) resulting from the issuance of Additional Subordinated Debt, if a Borrowing Base Deficiency then exists or results therefrom, then the Borrower shall 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 Debt Incurrence Proceeds of such Additional Subordinated Debt and (ii) such portion of the Borrowing Base Deficiency in existence immediately prior to such reduction.

(iii) Upon each reduction of the Borrowing Base under Section 2.02(e)(iii) from the occurrence of a Triggering Event, if a Borrowing Base Deficiency then exists or results therefrom, then the Borrower shall 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 such Triggering Event and (ii) such portion of the Borrowing Base Deficiency in existence immediately prior to such reduction.

(iv) 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.

(i) 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.

(ii) 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.

(d) Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the adoption of or any change in any applicable Legal Requirement or in the interpretation of any applicable Legal Requirement by any Governmental Authority makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its applicable 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) and if not prohibited by law, (A) 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, either prepay all of the Eurodollar Rate Advances made by such Lender then outstanding or Convert all of the Eurodollar Rate Advances made by such Lender then outstanding to Reference Rate Advances, and, in either case, pay all accrued interest on the principal amount prepaid or Converted to the date of such prepayment or Conversion and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment or Conversion being made on such date, (ii) to the extent the principal amount of Eurodollar Rate Advances are prepaid, 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 giving 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 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 other than Advances owing to a Defaulting Lender as provided in Section 2.17.

Section 2.06 Repayment of Advances; Mandatory Prepayment of Advances.

(a) Scheduled Maturity Date. 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 on the Commitment Termination Date or such earlier date pursuant to Section 7.02 or Section 7.03.

(b) Mandatory Prepayment of Advances. Without duplication of any amounts required to be paid and deposited under Section 2.05(b)(iii) above, in the event of any Material Disposition by the Borrower or any of its Subsidiaries which is a Disposition of Oil and Gas Properties that have a positive value in the most recently delivered Engineering Report or in the Engineering Report evaluated for the then effective Borrowing Base, within three Business Days after receipt of the proceeds thereof, the Borrower shall prepay the outstanding Advances in an amount equal to the least of (i) 100% of the Net Cash Proceeds resulting from such Material Disposition, (ii) 100% of the value, if any, assigned to such Oil and Gas Properties under the then effective Borrowing Base, as reasonably determined by the Administrative Agent, and (iii) the principal amount of Advances outstanding at such time; provided that, the prepayment under this Section 2.06(b) shall not be required after the occurrence of the Second Lien Debt Payoff. For the avoidance of doubt, the prepayments required under this Section 2.06(b) shall not constitute nor be construed as a consent to any Disposition that would not be permitted under the terms of this Agreement.

Section 2.07 Letters of Credit.

(a) Commitment. From time to time from the date of this Agreement until 30 days prior to the Commitment Termination 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) $15,000,000 and (B) 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 (or, in the case of any extension thereof, one year after the date of such extension) and (B) ten days prior to the Commitment Termination Date;

(iii) unless the 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 ▇▇▇▇▇ ▇▇▇▇▇ 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 (A) the date of the issuance or increase of a Letter of Credit, and (B) the date hereof as to the deemed issuance of the Existing Letters of Credit under Section 2.07(h), 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 10:00 a.m. (Dallas, Texas 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 that 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 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 a court determines in a final, non-appealable judgment were caused by the Issuing Lender's willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

(g) Cash Collateral Account.

(i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.04(c), 2.05(b), 2.17, 7.02(b), or 7.03(b), then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Administrative Agent's standard form assignment of deposit accounts, that the Administrative Agent requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent a first priority security interest in such account and the funds therein. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent 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 or Event of Default exists, (A) the Administrative Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (B) the Administrative Agent 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 or Event of Default, the Administrative Agent may apply any funds held in the Cash Collateral Account to the Obligations in any order determined by the Administrative Agent, regardless of any Letter of Credit Exposure that may remain outstanding. The Issuing Lender may in its sole discretion at any time direct the Administrative Agent to release to the Borrower any funds held in the Cash Collateral Account.

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

(h) 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.

(i) Defaulting Lender. If, at any time, a Defaulting Lender exists hereunder, then, at the request of the Issuing Lender subject to Section 2.17(c), the Borrower shall deposit funds with Administrative Agent into the Cash Collateral Account an amount equal to such Defaulting Lender's Pro Rata Share of the Letter of Credit Exposure.

Section 2.08 Fees.

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender having a Commitment a commitment fee in an amount equal to the Applicable Margin on the daily Unused Commitment Amount of such Lender, from the date of this Agreement 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) Letter of Credit Fees. Subject to Sections 2.17(c)(iii) and (iv), the Borrower agrees to pay (A) to the Administrative Agent for the pro rata benefit of the Lenders having a Commitment a per annum letter of credit fee for each Letter of Credit issued hereunder in an amount equal to the greater of (1) Applicable Margin for Eurodollar Rate Advances times the daily maximum amount available to be drawn under such Letter of Credit and (2) $750, and (B) to the Issuing Lender, a fronting fee for each Letter of Credit equal to 0.25% per annum times on the face amount of such Letter of Credit. The fronting fee shall be payable annually in advance on the date of the issuance of the Letter of Credit, and, in the case of an increase or extension only, on the date of such increase or such extension. The fee set forth in (A) above shall be computed on a quarterly basis in arrears and be due and payable on the last day of each March, June, September, and December commencing June 30, 2010.

(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.

(c) Facility and Other Fees. To the extent not otherwise included under Section 2.08(a) and (b), the Borrower agrees to pay to the Administrative Agent the fees required to be paid under the Fee Letters.

Section 2.09 Interest.

(a) Applicable Interest Rates. 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:

(i) 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 calendar quarter and on the date such Reference Rate Advance shall be paid in full.

(ii) 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 that occurs during such Interest Period three months from the first day of such Interest Period.

(b) 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 that 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 that 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 THAT 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 AMOUNT OF THE ADVANCES 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 12:00 p.m. (noon) (Dallas, Texas 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. 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), 2.12, 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 applicable 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 applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement.

(b) Computations. All computations of interest and fees shall be made by the Administrative Agent, on the basis of a year of 360 days 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. The provisions of this Section 2.11 shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Advances or participations in Letter of Credit Exposure to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 2.11 shall apply).

Section 2.12 Breakage Costs. If (a) any payment of principal of any Eurodollar Rate Advance or any Conversion of a 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 or Conversion 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 that 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. If any Change in Law shall (a) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Eurodollar Rate) or the Issuing Lender; (b) subject any Lender or the Issuing Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Rate Advance made by it, or change the basis of taxation of payments to such Lender or the Issuing Lender in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 2.14 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the Issuing Lender); or (c) impose on any Lender or the Issuing Lender or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Rate Advances made by such Lender or any Letter of Credit or participation therein; and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Advance (or of maintaining its obligation to make any such Advance), or to increase the cost to such Lender or the Issuing Lender of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the Issuing Lender hereunder (whether of principal, interest or any other amount) then, within thirty (30) days after demand by such Lender or the Issuing Lender, the Borrower will pay to such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered. 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.

(a) Capital Adequacy. If any Lender or the Issuing Lender determines that any Change in Law affecting such Lender or the Issuing Lender or any lending office of such Lender or such Lender’s or the Issuing Lender's holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Lender's capital or on the capital of such Lender’s or the Issuing Lender's holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Advances made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Lender, to a level below that which such Lender or the Issuing Lender or such Lender’s or the Issuing Lender's holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Lender's policies and the policies of such Lender’s or the Issuing Lender's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender or such Lender’s or the Issuing Lender's holding company for any such reduction suffered. 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. The Borrower shall pay such Lender or the Issuing Lender, as the case may be, the amount shown as due on any such certificate within thirty (30) days after receipt thereof.

(b) Letters of Credit. If any Change in Law 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.

(c) 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 or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for taxes, except as required by applicable law. If any withholding or deduction of tax is required by applicable Legal Requirement (as determined in the good faith discretion of an applicable withholding Agent), then (i) to the extent such taxes are Indemnified Taxes (including, for the avoidance of doubt, Other Taxes), the sum payable by the Borrower shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) the applicable withholding agent shall make such deductions and (iii) the applicable withholding agent shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with Legal Requirement.

(b) Other Taxes. Without limiting the provisions of clause (a) above, the Borrower agrees to (i) 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 hereunder or under any other Loan Document or from the execution, delivery or enforcement of, or otherwise with respect to, this Agreement, the Notes, or the other Loan Documents (hereinafter referred to as "Other Taxes"), or (ii) or at the option of the Administrative Agent, to timely reimburse the Administrative Agent, or applicable Lender or Issuing Lender for the payment of any Other Taxes.

(c) Indemnification. THE BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF INDEMNIFIED TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY INDEMNIFIED 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.

(d) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. Without limiting the generality of the foregoing, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable: (i) duly completed copies of Internal Revenue Service Form W-8BEN (or W-8BEN-E, as applicable) claiming eligibility for benefits of an income tax treaty to which the United States of America is a party; (ii) duly completed copies of Internal Revenue Service Form W-8ECI, (iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN (or W-8BEN-E, as applicable), or (v) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower to determine the withholding or deduction required to be made. To the extent a Foreign Lender is not the beneficial owner, such Foreign Lender shall deliver executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN (or W-8BEN-E, as applicable), IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable.

Any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax.

If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to

comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.14(d), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(e) Treatment of Certain Refunds. If the Administrative Agent, a Lender or the Issuing Lender determines, in its reasonable discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.14, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.14 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the Issuing Lender, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or the Issuing Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or the Issuing Lender in the event the Administrative Agent, such Lender or the Issuing Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent, any Lender or the Issuing Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person.

Section 2.15 Designation of a Different Lending Office. 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.

Section 2.16 Replacement of Lender. If (i) any Lender requests compensation under Section 2.13 or requires that the Borrower pay any additional amount pursuant to Section 2.14, (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 is 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 Applicable 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 amendment, waiver, consent or release with respect to this Agreement or any other Loan Document has been approved by the Required Lenders and such 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 2.16, the Borrower may terminate such Defaulting Lender's Commitment as provided in Section 2.04.

Section 2.17 Payments and Deductions to a Defaulting Lender.

(a) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.01(a), Section 2.07(d), or Section 2.10(d) then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid in cash.

(b) If a Defaulting Lender as a result of the exercise of a set-off shall have received a payment in respect of its outstanding Advances or pro rata share of Letter of Credit Exposure which results in its outstanding Advances and share of Letter of Credit Exposure being less than its Pro Rata Share of the aggregate outstanding Advances and Letter of Credit Exposure, then no payments will be made to such Defaulting Lender until such time as all amounts due and owing to the Lenders have been equalized in accordance with each Lender’s respective pro rata share of the aggregate outstanding Advances and Letter of Credit Exposure. Further, if at any time prior to the acceleration or maturity of the Advances, the Administrative Agent shall receive any payment in respect of principal of an Advance or a Reimbursement Obligation while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowings for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Pro Rata Share of all Advances then outstanding. After acceleration or maturity of the Advances, subject to the first sentence of this Section 2.17(b), all principal will be paid ratably as provided in Section 2.11.

(i) such Letter of Credit Exposure shall be automatically reallocated among the Non-Defaulting Lenders in accordance with their respective Pro Rata Share of such Defaulting Lender's share of the Letter of Credit Exposure (and each Lender is deemed to have purchased and assigned such participation interest in such reallocated portion of the Letter of Credit Exposure) but only to the extent that (A) the sum of each Non-Defaulting Lender's outstanding Advances plus its share of the Letter of Credit Exposure, after giving effect to the reallocation provided herein, does not exceed the lesser of such Non-Defaulting Lender's Pro Rata Share of the Borrowing Base and such Non-Defaulting Lender's Commitment, and (B) the conditions set forth in Section 3.02 are satisfied at such time; provided that, such reallocation will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Issuing Lender or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, then the Borrower shall, within one Business Day following notice by the Administrative Agent, cash collateralize such Defaulting Lender’s share of the Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.07(g) for so long as such Letter of Credit Exposure is outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s Letter of Credit Exposure pursuant to this Section 2.17 then the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.08 (b) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Letter of Credit Exposure is cash collateralized;

(iv) if the Letter of Credit Exposure of the Non-Defaulting Lenders is reallocated pursuant to clause (i) above, then the fees payable to the Lenders pursuant to Section 2.08(b) shall be adjusted in accordance with such Non-Defaulting Lenders’ Pro Rata Share;

(v) if any Defaulting Lender’s share of the Letter of Credit Exposure is neither cash collateralized nor reallocated pursuant to the preceding provisions, then, without prejudice to any rights or remedies of the Issuing Lender or any Lender hereunder, all letter of credit fees payable under Section 2.08(b) with respect to such Defaulting Lender’s share of the Letter of Credit Exposure shall be payable to the Issuing Lender until such Letter of Credit Exposure is cash collateralized and/or reallocated.

(d) In the event that the Administrative Agent, the Borrower and the Issuing Lender each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then (i) the Letter of Credit Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall be deemed to have purchased at par such of the Advances or participations in Letters of Credit of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Advances and Letter of Credit Exposure in accordance with its Pro Rata Share, and (ii) if no Default exists, then any cash collateral posted by the Borrower pursuant to clause (c)(ii) above with respect to such Lender shall be returned to the Borrower.

Additionally, there is no pending or, to the best knowledge of the Borrower, threatened action or proceeding instituted against the Borrower or any of its Restricted Subsidiaries which seeks to adjudicate the Borrower or any of its Restricted Subsidiaries as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property.

Section 4.08 Use of Proceeds. The proceeds of the Advances will be used by the Borrower for the purposes described in Section 5.09. The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U). No proceeds of any Advance will be used to purchase or carry any margin stock in violation of Regulation T, U or X.

Section 4.09 Investment Company Act. Neither the Borrower nor any of its Restricted Subsidiaries is an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended.

Section 4.10 Taxes.

(a) Reports and Payments. All Returns (as defined below in clause (c) of this Section) required to be filed by or on behalf of the Borrower, its Restricted Subsidiaries, 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, except where the failure to so file would not be reasonably expected to cause a Material Adverse Change and such Returns are and will be true, complete, and correct in all material respects; 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 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 4.10 shall mean all taxes, charges, fees, levies, or other assessments imposed by any federal, state, local, or foreign taxing authority, including without limitation, income, gross receipts, excise, real or personal property, sales, occupation, use, service, leasing, environmental, value added, transfer, payroll, and franchise taxes (and including any interest, penalties, or additions to tax attributable to or imposed on with respect to any such assessment).

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

Section 4.11 Pension Plans. All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan, and each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. No "accumulated funding deficiency" (as defined in Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of the Code. No Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits. Neither 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.

Since December 31,

2008, neither the business nor the material properties of the Merger Company and its Subsidiaries, 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 except to the extent any such change or event is disclosed in public filings made by the Merger Company with the Securities and Exchange Commission since such date but prior to February 19, 2010 (including any such disclosure in respect of the nature, magnitude or consequences of such change or event) and no event or circumstance that could cause a "Target Material Adverse Effect" as defined in the Merger Agreement has have occurred. Since the Effective Date, neither the business nor the material Properties of the Borrower and each of its Restricted Subsidiaries, 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.

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 its Restricted Subsidiaries on any of their presently or formerly owned, leased or operated Property and (ii) there are no facts, circumstances, conditions or occurrences with respect to any Property owned, leased or operated by the Borrower or any of its Restricted Subsidiaries that could reasonably be expected to form the basis of an Environmental Claim under Environmental Laws that could reasonably be expected to result in a Material Adverse Change.

Section 4.15 Permits, Licenses, Etc. The Borrower and its Restricted Subsidiaries possess all authorizations, Permits, licenses, patents, patent rights or licenses, trademarks, trademark rights, trade names rights and copyrights which are material to the conduct of their business.

Within 60 days after the Effective Date, and from time to time thereafter upon the reasonable request of the Administrative Agent, the Borrower shall take such actions and execute and deliver such documents and instruments as the Administrative Agent shall require to ensure that the Administrative Agent shall, at all times, have received satisfactory title information (including, if requested, supplemental or new title opinions addressed to it), which title information (a) shall collectively cover at least 80% of the present value of the Proven Reserves of the Borrower and its Restricted Subsidiaries as determined by the Administrative Agent, (b) shall be in form and substance acceptable to the Administrative Agent in its sole discretion, and (c) if requested by the Administrative Agent, shall include opinions regarding the before payout and after payout ownership interests held by the Borrower and the Borrower's Restricted Subsidiaries for all ▇▇▇▇▇ located on the Oil and Gas Properties covered thereby as to the ownership of Oil and Gas Properties of the Borrower and its Restricted Subsidiaries.

Section 5.11 Further Assurances; Cure of Title Defects. The Borrower shall, and shall cause each Restricted Subsidiary to, cure promptly any defects in the creation and issuance of the Notes and the execution and delivery of the Security Instruments and this Agreement. The Borrower hereby authorizes the Lenders or the Administrative Agent to file any financing statements without the signature of the Borrower to the extent permitted by applicable law in order to perfect or maintain the perfection of any security interest granted under any of the Loan Documents. The Borrower at its expense will, and will cause each Restricted Subsidiary to, promptly execute and deliver to the Administrative Agent upon its reasonable request all such other documents, agreements and instruments to comply with or accomplish the covenants and agreements of the Borrower or any Restricted Subsidiary, as the case may be, in the Security Instruments and this Agreement, or to further evidence and more fully describe the collateral intended as security for the Notes, or to correct any omissions in the Security Instruments, or to state more fully the security obligations set out herein or in any of the Security Instruments, or to perfect, protect or preserve any Liens created pursuant to any of the Security Instruments, or to make any recordings, to file any notices or obtain any consents, all as may be necessary or appropriate in connection therewith or to enable the Administrative Agent to exercise and enforce its rights and remedies with respect to any Collateral. Within 60 days after (a) a request by the Administrative Agent or the Lenders to cure any title defects or exceptions that are not Permitted Liens raised by such information or (b) a notice by the Administrative Agent that the Borrower has failed to comply with Section 5.10 above, the Borrower shall

(i) cure such title defects or exceptions that are not Permitted Liens or substitute acceptable Oil and Gas Properties with no title defects or exceptions except for Permitted Liens covering Collateral of an equivalent value and (ii) deliver to the Administrative Agent satisfactory title evidence (including supplemental or new title opinions meeting the foregoing requirements) in form and substance acceptable to the Administrative Agent in its reasonable business judgment as to the Borrower's and its Restricted Subsidiaries' ownership of such Oil and Gas Properties and the Administrative Agent's Liens and security interests therein as are required to maintain compliance with Section 5.10. If, within such 60-day period, the Borrower fails to cure any such title defect or exception as required under the foregoing clause (a) or fails to deliver the title evidence required under the foregoing clause (b), such failure shall not be a Default (other than if such failure otherwise constitutes a Default under Section 7.01(n)), but instead the Administrative Agent shall have the right to exercise the following remedy in its sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent. To the extent that the Administrative Agent is not satisfied with title to any portion of any Oil and Gas Property after such 60-day period has elapsed, such unacceptable Oil and Gas Property shall not count towards the 80% requirement under Section 5.10 above, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then effective Borrowing Base shall be reduced by an amount as determined by the Administrative Agent or, if elected by the Required Lenders, by the Required Lenders, to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% (by value) of the Borrower’s and its Restricted Subsidiaries’ Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice. If the Borrowing Base is reduced pursuant to this Section 5.11 and such a reduction causes a Borrowing Base Deficiency, then (x) Borrower shall prepay the Advances or make deposits into the Cash Collateral Account to provide cash collateral for the Letters of Credit, in three consecutive monthly installments each equal to one-third 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, with each prepayment of Advances 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, and (y) such title defect or exception giving rise to such Borrowing Base reduction shall not constitute an Event of Default hereunder (other than to the extent it constitutes a Default under Section 7.01(n)), unless such title defect or exception is prohibited under Section 6.01. For the avoidance of doubt and for all purposes under this Agreement, if title to any of the Oil and Gas Property of the Borrower or Restricted Subsidiary (or any material part thereof) shall become the subject matter of litigation before any Governmental Authority or arbitrator that could reasonably be expected to result in a Material Adverse Change with respect to the Borrower's or such Restricted Subsidiary’s title to such Oil and Gas Properties, taken as a whole, then such litigation may be deemed to be a title defect or exception that is not a Permitted Lien regardless of whether the Borrower’s or such Restricted Subsidiary’s record title is then effected.

Section 5.12 Material Agreements. The Borrower shall, and shall cause each Restricted Subsidiary to, comply with all material terms, conditions, or covenants of any material contract or agreement to which the Borrower or any of its Restricted Subsidiaries is a party or by which they or their Properties may be bound except to the extent where the failure to do so could not reasonably be expected to cause a Material Adverse Change.

Section 5.13 Leases; Development and Maintenance. The Borrower will, and will cause its Restricted Subsidiaries to, except to the extent failure to do any of the matters set forth below would not have a Material Adverse Change: (a) pay and discharge promptly, or cause to be paid and discharged promptly, all rentals, delay rentals, royalties, overriding royalties, payments out of production and other indebtedness or obligations accruing under, and perform or cause to be performed each and every act, matter or thing required by each and all of, the oil and gas leases and all other agreements and contracts

constituting or affecting the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries (except where the amount thereof is being contested in good faith by appropriate proceedings), (b) do all other things necessary to keep unimpaired its rights thereunder and prevent any forfeiture thereof or default thereunder, and operate or cause to be operated such Properties as a prudent operator would in accordance with industry standard practices and in compliance with all applicable proration and conservation Legal Requirements and any other Legal Requirements of every Governmental Authority, whether state, federal, municipal or other jurisdiction, from time to time constituted to regulate the development and operations of oil and gas properties and the production and sale of oil, gas and other Hydrocarbons therefrom, and (c) maintain (or cause to be maintained) the Leases, ▇▇▇▇▇, units and acreage to which the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries pertain in a prudent manner consistent with industry standard practices.

(iii) Notwithstanding anything herein to the contrary, at no time shall any Subsidiary be an Unrestricted Subsidiary if it is a “restricted subsidiary” for purposes of any indenture, credit agreement or similar agreement that contains the concept of “restricted” and “unrestricted” subsidiaries or otherwise provides a guarantee of, or provides collateral security for, the obligations thereunder.

(b) The Borrower shall not designate any Restricted Subsidiary as an Unrestricted Subsidiary.

(c) In the case of the acquisition, formation or designation of a Restricted Subsidiary, such new Restricted Subsidiary shall be deemed to have made or acquired all Investments owned by it and incurred all Indebtedness and other obligations owing by it and all Liens to which it or any of its properties are subject, on the date of such designation, acquisition, or formation.

Section 5.15 Designation of Senior Debt. The Borrower shall, and shall cause each Restricted Subsidiary to, designate all Obligations as “designated senior indebtedness” under any subordinated note or indenture documents applicable to it, to the extent provided for therein, including but not limited to the Senior Unsecured Notes.

The Borrower and the other Loan Parties hereby instruct each such counsel to deliver such legal opinions.

ARTICLE VIII

THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER

Section 8.01 Authorization and Action. Each Lender that is an Existing Lender is deemed to have appointed ▇▇▇▇▇ Fargo Bank, N.A., as the administrative agent and the issuing lender under the Existing Credit Agreement; provided, however, ▇▇▇▇▇ Fargo Bank, N.A. does not assume and shall not be obligated to pay, perform or discharge any claim, debt, obligation, expense or liability of MUFG Union Bank, N.A., if any, of any kind, whether known or unknown, absolute or contingent, under the Loan Documents (as defined in the Existing Credit Agreement) or otherwise, arising out of any act or omission occurring on or before the date hereof under the Loan Documents (as defined in the Existing Credit Agreement). The Borrower, the Existing Lenders, ▇▇▇▇▇ Fargo Bank, N.A. and MUFG Union Bank, N.A. agree that Section 8.06 of the Existing Credit Agreement shall apply to MUFG Union Bank, N.A.'s resignation pursuant to the Assignment; provided that, such parties hereby waive the 30 days prior written notice required thereunder as to such resignation. 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 Required 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 that exposes the Administrative Agent to personal liability or that 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) 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 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 CLAIMS AND ANY LIABILITIES ARISING UNDER ENVIRONMENTAL LAW, PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR DISBURSEMENTS RESULTING FROM THE ADMINISTRATIVE AGENT'S OR THE ISSUING LENDER'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AS DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT. WITHOUT LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE 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. Notwithstanding the foregoing, the preceding provisions of this Section 8.05 shall apply only to liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that were incurred by or asserted against the Administrative Agent or the Issuing Bank in their respective capacities as such, or against any Affiliate thereof, or any of such Person's or Affiliate's respective directors, officers, employees, or agents, acting for the Administrative Agent or Issuing Bank in connection with such capacity. 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 not less than 30 days prior written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders upon receipt of written notice from the Required Lenders to such effect. Upon receipt of notice of any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, if any Event of Default has not occurred and is not 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 Required 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 Required 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 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 Required Lenders appoint a successor Administrative Agent or Issuing Lender, as applicable, as provided for above in this paragraph. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Administrative Agent or Issuing Lender, and the retiring Administrative Agent or Issuing Lender shall be discharged

from its duties and obligations under this Agreement and the other Loan Documents, except that the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent's or Issuing Lender's resignation or removal hereunder as Administrative Agent or Issuing Lender, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Loan Documents.

a Subsidiary from its respective Guaranty, upon such Subsidiary ceasing to be a Restricted Subsidiary of the Borrower pursuant to a transaction permitted hereunder; or (vi) if approved, authorized or ratified in writing by the applicable Required Lenders or all the Lenders, as the case may be, as required by Section 9.01.

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 Guaranty, 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).

(a) INDEMNIFICATION. THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT, THE LENDERS, THE ISSUING LENDER, AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AND AGENTS (EACH, AN “INDEMNIFIED PARTY”) FROM, AND DISCHARGE, RELEASE, AND HOLD EACH INDEMNIFIED PARTY HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, OR DAMAGES THAT MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST SUCH INDEMNIFIED PARTY IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY ANY INDEMNIFIED PARTY UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (A) INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF SUCH INDEMNIFIED PARTY'S OWN NEGLIGENCE OR STRICT LIABILITY, (B) INCLUDING WITHOUT LIMITATION ENVIRONMENTAL CLAIMS AND ANY LIABILITIES ARISING UNDER ENVIRONMENTAL LAW, AND (C) INCLUDING WITHOUT LIMITATION ANY SUCH OTHER LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSES RESULTING FROM ANY LITIGATION, LEGAL PROCEEDING OR OTHER TYPE OF ACTION, REGARDLESS OF WHETHER ANY INDEMNIFIED PARTY IS PARTY TO SUCH LITIGATION, LEGAL PROCEEDING OR OTHER ACTION, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSES INCURRED BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED AS DETERMINED BY A COURT OF COMPETENT JURISDICTION BY A FINAL AND NONAPPEALABLE JUDGMENT. In the case of an investigation, litigation or proceeding to which the

indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, any Subsidiary or Affiliate thereof, any equityholder or creditor thereof, or an Indemnified Party. The Borrower hereby also agrees that no Indemnified Party will have any liability (whether direct or indirect, in contract or tort, or otherwise) to the Borrower, any Subsidiary or Affiliate thereof, or any equity holder or creditor thereof arising out of, related to or in connection with any aspect of the transactions contemplated hereby, except to the extent such liability is determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s own gross negligence or willful misconduct. The Borrower shall not, nor shall it permit any of its Subsidiaries to, without the prior written consent of each Indemnified Party affected thereby (which consent will not be unreasonably withheld), settle any threatened or pending claim or action that would give rise to the right of any Indemnified Party to claim indemnification hereunder unless such settlement (a) includes a full and unconditional release of all liabilities arising out of such claim or action against such Indemnified Party and (b) does not include any statement as to or an admission of fault, culpability or failure to act by or on behalf of any Indemnified Party.

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

Section 9.08 Confidentiality. The Administrative Agent, the Issuing Lender, and each Lender (each a "Lending Party") agree to keep confidential any information furnished or made available to it by the Borrower pursuant to this Agreement and identified by the Borrower as proprietary or confidential; provided that nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, agent, or advisor of any Lending Party or Affiliate of any Lending Party for purposes of administering, negotiating, considering, processing, implementing, syndicating, assigning, or evaluating the credit facilities provided herein and the transactions contemplated hereby, (b) to any other Person if directly incidental to the administration of the credit facilities provided herein, (c) as required by any Legal Requirement, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any regulatory agency or authority or in connection with any pledge or assignment pursuant to Section 9.06(f), (f) that is or becomes available to the public or that is or becomes available to any Lending Party other than as a result of a disclosure by any other Lending Party prohibited by this Agreement, (g) in connection with any litigation relating to this Agreement or any other Loan Document to which such Lending Party or any of its Affiliates may be a party, (h) to the extent necessary in connection with the exercise of any right or remedy under this Agreement or any other Loan Document, and (i) to any actual or proposed participant or assignee, in each case, subject to provisions similar to those contained in this Section 9.08. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in this Agreement shall (a) restrict any Lending Party from providing information to any bank or other regulatory or governmental authorities, including the Federal Reserve Board and its supervisory staff; (b) require or permit any Lending Party to disclose to the Borrower or any

Affiliate thereof that any information will be or was provided to the Federal Reserve Board or any of its supervisory staff; or (c) require or permit any Lending Party to inform the Borrower or any Affiliate thereof of a current or upcoming Federal Reserve Board examination or any nonpublic Federal Reserve Board supervisory initiative or action.
