Section 2.01 Commitment for Advances.

(a) Advances. Each Lender severally agrees, on the terms and conditions set forth in this Agreement (including, without limitation, the terms set forth in Section 3.01, 3.02 and 3.03), to make Advances to the Borrower from time to time on any Business Day during the period from the date of this Agreement until the Commitment Termination Date in an amount for each Lender not to exceed such Lender's Unused Commitment Amount. Each Borrowing shall, in the case of Borrowings consisting of Reference Rate Advances, be in an aggregate amount not less than $250,000 and in integral multiples of $100,000 in excess thereof, and in the case of Borrowings consisting of Eurodollar Rate Advances, be in an aggregate amount not less than $500,000 and in integral multiples of $100,000 in excess thereof, and in each case shall consist of Advances of the same Type made on the same day by the Lenders ratably according to their respective Commitments. Within the limits of each Lender's Commitment, and subject to the terms of this Agreement, the Borrower may from time to time borrow, prepay, and reborrow Advances.

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

Section 2.02 Borrowing Base.

(a) Borrowing Base. The initial Borrowing Base in effect as of Effective Date has been set by the Administrative Agent and the Lenders and acknowledged by the Borrower as Sixty Million Dollars ($60,000,000). Such initial Borrowing Base shall remain in effect until the next redetermination made pursuant to this Section 2.02. The Borrowing Base shall be determined in accordance with the standards set forth in Section 2.02(d) and is subject to periodic redetermination pursuant to Sections 2.02(b) and 2.02(c).

(b) Calculation of the Borrowing Base.

(i) The Borrower shall deliver to the Administrative Agent and each of the Lenders on or before each March 1, beginning March 1, 2013, an Independent Engineering Report dated effective as of the immediately preceding January 1, and such other information as may be reasonably requested by any Lender with respect to the Borrowing Base Properties included or to be included in the Borrowing Base. Upon receipt of such information, the Administrative Agent shall, in the normal course of business (but in any event within 30 days after receipt of such information), propose to the Lenders a new Borrowing Base (for purposes of this subsection, the "Proposed Borrowing Base"). After having received notice of such proposal,

the Lenders shall have 14 days to agree or disagree with the Proposed Borrowing Base. If at the end of the 14 days, any Lender has not communicated its approval or disapproval to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If at the end of such 14 days, the Required Lenders (or all of the Lenders if the Borrowing Base is to be increased) have approved or have been deemed to have approved the Proposed Borrowing Base, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.02(b)(iii). To the extent that within such 14 day period the Administrative Agent has not received the requisite number of approvals from the Lenders, the requisite number of Lenders shall, within a reasonable period of time, agree on a new Borrowing Base.

(ii) The Borrower shall deliver to the Administrative Agent and each Lender on or before each September 30, beginning September 30, 2012, 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 with respect to the Borrowing Base Properties included or to be included in the Borrowing Base. Upon receipt of such information, the Administrative Agent shall, in the normal course of business (but in any event within 30 days after receipt of such information), propose to the Lenders a new Borrowing Base (for purposes of this subsection, the "Proposed Borrowing Base"). After having received notice of such proposal, the Lenders shall have 14 days to agree or disagree with the Proposed Borrowing Base. If at the end of the 14 days, any Lender has not communicated its approval or disapproval to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If at the end of such 14 days, the Required Lenders (or all of the Lenders if the Borrowing Base is to be increased) have approved or have been deemed to have approved the Proposed Borrowing Base, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.02(b)(iii). To the extent that within such 14 day period the Administrative Agent has not received the requisite number of approvals from the Lenders, the requisite number of Lenders shall, within a reasonable period of time, agree on a new Borrowing Base.

(iii) If the Borrower or any Subsidiary shall terminate or create any off-setting positions which have the economic effect of terminating any Hedge Contract (regardless of how evidenced) upon which the Lenders relied in determining the Borrowing Base, and which would adversely affect the Borrowing Base (after giving effect to any replacement Hedge Contract), then, to the extent required by the Required Lenders, the Borrowing Base shall be reduced in an amount determined by the Required Lenders equal to the value given to such Hedge Contracts in the Borrowing Base.

(iv) If, during any six-month period between scheduled Borrowing Base redeterminations, the Borrower or its Subsidiaries shall sale, lease, transfer, assign, farm-out, convey or otherwise dispose (including casualty events) of any Oil and Gas Properties to which Proven Reserves have been attributed in the most recent Engineering Report delivered pursuant to this Agreement, which individually or in the aggregate have a discounted present value (as set forth in the most recent Engineering Report delivered to the Lenders under this Agreement) in excess of 5% of the then effective Borrowing Base, then, to the extent required by the Required Lenders, the Borrowing Base shall be reduced by an amount determined by the Required Lenders.

(v) After a redetermined Borrowing Base is approved or deemed approved by the Required Lenders or all of the Lenders, as applicable, the Administrative Agent shall notify the Borrower of the amount of the redetermined Borrowing Base, and such amounts shall become the Borrowing Base, effective and applicable to the Borrower, and subject to the other

provisions of this Agreement, shall be the basis on which the Borrowing Base shall thereafter be calculated until the effective date of the next redetermination of the Borrowing Base as set forth in this Section 2.02.

(vi) In the event that the Borrower does not furnish to the Administrative Agent and the Lenders the Independent Engineering Report, Internal Engineering Report or other information specified in clauses (i) and (ii) above by the date specified therein, the Administrative Agent and the Lenders may nonetheless redetermine the Borrowing Base and redesignate the Borrowing Base from time-to-time thereafter in their sole discretion until the Administrative Agent and the Lenders receive the relevant Independent Engineering Report, Internal Engineering Report, or other information, as applicable, whereupon the Administrative Agent and the Lenders shall redetermine the Borrowing Base as otherwise specified in this Section 2.02.

(vii) 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, except as expressly disclosed by the Borrower to the Administrative Agent and the Lenders pursuant to Section 5.06 or otherwise, (A) the Borrower and the Guarantors, as applicable, own the Borrowing Base Properties specified therein with at least 90% (by value) of the Proven Reserves covered therein subject to an Acceptable Security Interest and free and clear of any Liens (except Permitted Liens), and (B) on and as of the date of such Engineering Report each Borrowing Base Property described as "proved developed" therein was developed for oil and gas, and the xxxxx pertaining to such Borrowing Base Properties that are described therein as producing xxxxx ("Xxxxx"), were each producing oil and gas in paying quantities, except for Xxxxx that were utilized as water or gas injection xxxxx or as water disposal xxxxx or xxxxx temporarily shut-in for workovers or other repairs in the ordinary course of business.

(c) Interim Redetermination. In addition to the Borrowing Base redeterminations provided for in Section 2.02(b), the Administrative Agent and the Lenders may (i) in their sole discretion make one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations and (ii) at the request of the Borrower make one additional redetermination of the Borrowing Base during any six-month period between scheduled redeterminations, and in any case, based on such information as the Administrative Agent and the Lenders deem relevant (but in accordance with Section 2.02(d)). The party requesting the redetermination shall give the other party at least 10 days' prior written notice that a redetermination of the Borrowing Base pursuant to this paragraph (c) is to be performed. In connection with any redetermination of the Borrowing Base under this Section 2.02(c), the Borrower shall provide the Administrative Agent and the Lenders with such information regarding the Borrower and the Guarantors' business (including its Borrowing Base Properties, the Proven Reserves attributable thereto, and production relating thereto) as the Administrative Agent may request, including an updated Independent Engineering Report. The Administrative Agent shall promptly notify the Borrower in writing of each redetermination of the Borrowing Base pursuant to this Section 2.02(c) and the amount of the Borrowing Base as so redetermined.

(d) Standards for Redetermination. Each redetermination of the Borrowing Base by the Administrative Agent and the Lenders pursuant to this Section 2.02 shall be made (i) in the sole discretion of the Administrative Agent and the Lenders (but in accordance with the other provisions of this Section 2.02(d)), (ii) in accordance with the Administrative Agent's and the Lenders' customary internal standards and practices for valuing and redetermining the value of Oil and Gas Properties in connection with reserve based oil and gas loan transactions, (iii) in conjunction with the most recent Independent Engineering Report or Internal Engineering Report, as applicable, or other information received by the Administrative Agent and the Lenders relating to the Proven Reserves of the Borrower and the

Guarantors, and (iv) based upon the estimated value of the Proven Reserves owned by the Borrower and the Guarantors as determined by the Administrative Agent and the Lenders. In valuing and redetermining the Borrowing Base, the Administrative Agent and the Lenders may also consider the business, financial condition, and Debt obligations of the Borrower and its Subsidiaries and such other factors as the Administrative Agent and the Lenders customarily deem appropriate, 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 each contains an equity cushion (market value in excess of loan value), which is essential for the adequate protection of the Administrative Agent and the Lenders. No Proven Reserves shall be included or considered for inclusion in the Borrowing Base unless the Administrative Agent and the Lenders shall have received, at the Borrower's expense, evidence of title satisfactory in form and substance to the Administrative Agent and evidence satisfactory to the Administrative Agent that the Administrative Agent has an Acceptable Security Interest in the Borrowing Base Properties relating thereto pursuant to the Security Instruments and subject to Sections 5.10 and 5.11 of this Agreement. At all times after the Administrative Agent has given the Borrower notification of a redetermination of the Borrowing Base under this Section 2.02, the Borrowing Base shall be equal to the redetermined amount or such lesser amount designated by the Borrower and disclosed in writing to the Administrative Agent and the Lenders until the Borrowing Base are subsequently redetermined in accordance with this Section 2.02.

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

(ii) if any Lender shall, at least one Business Day before the date of any requested Borrowing, Conversion, or continuation, notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its 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) of this Section 2.03, the Administrative Agent shall forthwith so notify the Borrower and the Lenders and such Advances shall be made available to the Borrower on the date of such Borrowing as Reference Rate Advances or, if an existing Advance, Convert into Reference Rate Advances.

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

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

Section 2.04 Reduction of the Commitments.

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

(b) 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.

If any such notice is given, the Borrower shall prepay the Advances in whole or ratably in part (other than Advances owing to a Defaulting Lender as provided in Section 2.16) in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment being made on such date; provided, however, that each partial prepayment with respect to: (A) any amounts prepaid in respect of Eurodollar Rate Advances shall be applied to Eurodollar Rate Advances comprising part of the same Borrowing; (B) any prepayments made in respect of Reference Rate Advances shall be made in minimum amounts of $100,000 and in integral multiples of

(i) prepay Advances or, if the Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure, such that the Borrowing Base deficiency is cured within 10 days after the date such deficiency notice is received by the Borrower from the Administrative Agent;

(ii) pledge as Collateral for the Obligations additional Oil and Gas Properties acceptable to the Required Lenders in their sole discretion (and deliver such title evidence thereto to the extent required under Section 5.10 and deliver Engineering Reports covering such Oil and Gas Properties acceptable to the Required Lenders) such that the Borrowing Base deficiency is cured within 30 days after the date such deficiency notice is received by the Borrower from the Administrative Agent;

(iii) (A) 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 repay the Advances and make deposits into the Cash Collateral Account to provide cash collateral for the Letters of Credit, each in five equal consecutive 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 due date, and (B) make such payments and deposits within such time periods (provided, however, that if at the end of such five (5) month period, the aggregate principal balance of the Advances plus the Letter of Credit Exposure again exceeds the lesser of (x) the Borrowing Base or (y) the aggregate Commitments, interest shall accrue on the Advances at the Default Rate until such time Borrowing Base is equal to or exceeds the aggregate principal balance of the Advances); or

(iv) (A) 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 (ii) and clause (iii) above, and also indicating the amount to be prepaid in installments and the amount to be provided as additional Collateral, and (B) make such six equal consecutive monthly installments and deliver such additional Collateral within the time required under clause (ii) and clause (iii) above.

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 clauses (i), (iii) and (iv) of this Section 2.05(b) shall be applied to the Advances as requested by the Borrower if no Default then exists or, if a Default then exists, 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. 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 requested by the Borrower if no Default then exists or, if a Default then exists, as determined by the Administrative Agent.

(ii) Defaulting Lender. At any time when a Lender is then a Defaulting Lender, the Borrower, at Borrower's election, may elect to terminate such Defaulting Lender's Commitment hereunder; provided that (A) such termination must be of all of the Defaulting Lender's Commitment, (B) the Borrower shall pay all amounts owed by the Borrower to such Defaulting Lender in such Lender's capacity as a 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 (subject to Section 2.16(a)(iii)), and letter of credit fees (subject to Section 2.15(a)(iii) but specifically excluding any amounts owing under Section 2.12 as result of such payment of such Advances) and shall deposit with the Administrative Agent into the Cash Collateral Account cash collateral in the amount equal to such Defaulting Lender's Applicable Percentage of the Letter of Credit Exposure (but including any such portion thereof that has been reallocated pursuant to Section 2.15), (C) a Defaulting Lender's Commitment may be terminated by the Borrower under this Section 2.1(c)(ii) 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, and (D) no Default has occurred and is continuing at the time of such election and termination. 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 (ii) and the payment and deposit of amounts required to be made by the Borrower under clause (B) and (C) above, (1) such Defaulting Lender shall cease to be a " Lender" hereunder for all purposes except that such Lender's rights and obligations as a Lender under Sections 2.05(d), 2.13, 2.14, 8.03, 9.04 and 9.07 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a " Lender" hereunder, (2) such Defaulting Lender's Commitment shall be deemed terminated, and (3) such Defaulting Lender shall be relieved of its obligations hereunder as a " Lender" except as to its obligations under Section 8.03 and any other obligations that expressly survive, which obligations shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a " Lender" hereunder, provided that, any such termination will not be deemed to be a waiver or release of any claim by the Borrower, the Administrative Agent, Issuing Lender or any Lender may have against such Defaulting Lender.

(d) Illegality. If any Lender shall notify the Administrative Agent and the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful for such Lender or its 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 12:00 noon Jackson, Mississippi, time (A) if not prohibited by law, on the last day of the Interest Period for each outstanding Eurodollar Rate Advance made by such Lender or (B) if required by such notice, on the second Business Day following its receipt of such notice, prepay all of the Eurodollar Rate Advances

made by such Lender then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment being made on such date, (ii) such Lender shall simultaneously make a Reference Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Lender, and (iii) the right of the Borrower to select Eurodollar Rate Advances from such Lender for any subsequent Borrowing shall be suspended until such Lender 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 this Section 2.05, and all notices given pursuant to this Section 2.05 shall be irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this Section 2.05 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

Section 2.06 Repayment of Advances. Borrower shall repay to Administrative Agent for the ratable benefit of the Lenders the outstanding principal amount of each Advance, together with any accrued interest thereon, on the earlier of: (i) the Maturity Date, or (ii) such earlier date as may be required pursuant to Section 2.05(b), Section 7.02 or Section 7.03.

Section 2.07 Letters of Credit.

(a) Commitment. From time to time from the date of this Agreement until 10 days prior to the Maturity Date, at the request of the Borrower, the requested Issuing Lender shall, on the terms and conditions set forth in this Agreement (including, without limitation, the terms of Section 3.01), 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) the Letter of Credit Sublimit 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 aggregate outstanding principal amount of all Advances at such time;

(ii) if such Letter of Credit has an Expiration Date later than 10 days prior to the Maturity Date;

(iii) if such Letter of Credit has an expiration date later than one year after its issuance or extension; provided that any such Letter of Credit with a one-year tenor may expressly provide that it is renewable at the option of the applicable Issuing Lender for additional one-year periods;

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

(v) if such Letter of Credit is a standby letter of credit, it does not support the repayment of indebtedness for borrowed money of any Person;

(vi) unless the Borrower has delivered to the applicable Issuing Lender a completed and executed Letter of Credit Application;

(vii) 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 applicable Issuing Lender;

(viii) by Regions Bank, as Issuing Lender, if such issuance, increase or extension would cause the sum of (A) the Reimbursement Obligations owing to Regions Bank, as Issuing Lender plus (B) the aggregate undrawn maximum face amount of all outstanding Letters of Credit issued by Regions Bank, as Issuing Lender, to exceed $10,000,000;

(ix) by any Issuing Lender (other than Regions Bank) unless such issuance, increase or extension, if made by Regions Bank as Issuing Lender, would cause the sum of (A) the Reimbursement Obligations owing to Regions Bank, as Issuing Lender plus (B) the aggregate undrawn maximum face amount of all outstanding Letters of Credit issued by Regions Bank, as Issuing Lender would exceed $10,000,000;

(x) if any Lender is at such time a Defaulting Lender hereunder, unless the applicable Issuing Lender has entered into satisfactory arrangements with the Borrower or such Defaulting Lender to eliminate such Issuing Lender's risk with respect to such Defaulting Lender (including depositing cash collateral into the Cash Collateral Account equal to the Defaulting Lender's Pro Rata Share of the Letter of Credit Exposure attributable to such Letter of Credit, or if acceptable to such Issuing Lender, the Administrative Agent and the Borrower, calculating each Lender's participation in the Letter of Credit subject to such issuance, increase or extension without giving effect to such Defaulting Lender's Pro Rata Share; provided, however, that after giving effect thereto, no Lender's participation in such Letter of Credit would exceed its Unused Commitment Amount); and

(xi) if any Lender is at such time a Defaulting Lender or a Potential Defaulting Lender hereunder, unless the Issuing Lender has entered into satisfactory arrangements with the Borrower or such Lender to eliminate the Issuing Lender's Fronting Exposure with respect to such Lender.

If the terms of any Letter of Credit Application referred to in the foregoing clause (vi) conflicts with the terms of this Agreement, the terms of this Agreement shall control.

(b) Participations. Upon the date of the issuance or increase of a Letter of Credit, the applicable 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 such 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 applicable Issuing Lender shall promptly notify the Administrative Agent and each such participant Lender having a Commitment by telephone, or telecopy of each Letter of Credit issued, increased, or extended, 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 to the applicable Issuing Lender and the Administrative Agent not later than 2:00 p.m. Jackson, Mississippi, time on the third Business Day before the date of the proposed issuance, increase, or

extension of the Letter of Credit, and the applicable Issuing Lender shall (i) promptly after receipt of such Letter of Credit Application, confirm with the Administrative Agent that the Administrative Agent has also received a copy of such Letter of Credit Application and, if not, the such Issuing Lender shall notify the Administrative Agent of the contents thereof, and (ii) give to each other Lender prompt notice thereof by 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 to the applicable Issuing Lender. After the applicable 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 and so long as the Issuing Lender has not received a notice (in writing, by facsimile or by e-mail) of the limitation set forth in Section 2.07(a)(i) or (ix), such 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 applicable Issuing Lender an amount equal to any amount paid by such Issuing Lender under any Letter of Credit. In the event the applicable 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, such 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 such Issuing Lender. Upon such notice from the Administrative Agent, each Lender shall promptly reimburse such 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 such Issuing Lender. If such reimbursement is not made by any Lender to the applicable Issuing Lender on the same day on which the Administrative Agent notifies such Lender to make reimbursement to such Issuing Lender hereunder, such Lender shall pay interest on its Pro Rata Share thereof to such 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 applicable Issuing Lender as Reference Rate Advances under a Borrowing requested by the Borrower (without regard to the minimums and multiples referenced in Section 2.1) to reimburse such Issuing Lender which have been transferred to such 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 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), any 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 any Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

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

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit or the Borrower's rights under Section 2.07(f).

(f) Liability of Issuing Lenders. 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. No 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 any 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 AN ISSUING LENDER'S OWN NEGLIGENCE),

except that the Borrower may make a claim against such Issuing Lender for any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower claims to have been caused by such Issuing Lender's willful misconduct or gross negligence or such Issuing Lender's willful failure to pay under any Letter of Credit after presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit; provided that, such Issuing Lender shall not be required to reimburse or pay the Borrower for any such damages unless a court determines in a final, non-appealable judgment that such damages were caused by such Issuing Lender's willful misconduct or gross negligence or such Issuing Lender's willful failure to pay under any Letter of Credit after presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, an 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 the terms hereof, 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 excess of the amount required to be on deposit to cure a Borrowing Base Deficiency pursuant to Section 2.05(b). 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 Administrative Agent may in its sole discretion at any time 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 and 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.

(iv) If a Defaulting Lender or a Potential Defaulting Lender deposits funds in a deposit account with the Administrative Agent pursuant to the terms of this Section 2.07(g)(iv) and Section 2.07(h), then such Lender and the Administrative Agent shall establish such cash collateral account and such Lender 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 such account and grant the Administrative Agent a first priority security interest in such account and the funds therein. Such Defaulting Lender hereby pledges to the Administrative Agent and grants the Administrative Agent a security interest in such collateral account, whenever established, all funds held in such account from time to time, and all proceeds thereof as security for the payment of the Letter of Credit Obligations of the Borrower to be applied as provided in Section 2.07(h) below.

(h) Defaulting Lender - Cash Collateral. Subject to Section 2.16, if, at any time, a Defaulting Lender or a Potential Defaulting Lender exists hereunder, then, at the request of Issuing Lender subject to Section 2.16, the Borrower shall fully Cash Collateralize the Issuing Lender's Fronting Exposure with respect to such Defaulting Lender or Potential Defaulting Lender (determined after giving effect to Section 2.16 and any Cash Collateral provided by such Defaulting Lender). Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.07(h) or Section 2.16 in respect of Letters of Credit shall

be applied to the satisfaction of the Defaulting Lender's obligation to fund participations in respect of Letter of Credit Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein. Cash Collateral (or the appropriate portion thereof) provided to reduce the Issuing Lender's Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.07(h) following (a) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (b) the determination by the Administrative Agent and Issuing Lender that there exists excess Cash Collateral; provided that, (1) subject to Section 2.16, the Person providing Cash Collateral and the Issuing Lender may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations, (2) to the extent that such Cash Collateral was provided by the Borrower, such Cash Collateral shall remain subject to the security interest granted pursuant to the Loan Documents, and (3) to the extent that such Cash Collateral was provided by the Borrower, during the existence of an Event of Default the application of such Cash Collateral shall be subject to Section 2.07(g)(ii) above, the second sentence in this Section 2.07(h) and Section 2.16(a)(ii).

Section 2.08 Fees.

(a) Commitment Fee. The Borrower agrees to pay to the Administrative Agent for the account of each Lender having a Commitment a commitment fee at a per annum rate equal to the Commitment Fee Rate on the daily Unused Commitment Amount of such Lender, from the date of this Agreement until the Commitment Termination Date; provided that, no such 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, 2012, and continuing thereafter through and including the Commitment Termination Date.

(b) Letter of Credit Fees.

(i) 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 (y) a per annum rate equal to the Applicable Margin then in effect for Eurodollar Rate Advances on the face amount of such Letter of Credit for the period such Letter of Credit is to be outstanding and (z) $500.00, and (B) to each Issuing Lender, a fronting fee for each Letter of Credit issued by such Issuing Lender equal to 0.125% per annum on the face amount of such Letter of Credit for the period such Letter of Credit is to be outstanding. The fees set forth in (A) and (B) above shall be computed quarterly in arrears and shall be due and payable on the last day of each March, June, September, and December and on the Commitment Termination Date.

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

(c) Other Fees. The Borrower agrees to pay to (i) Regions Bank the fees provided for in the Fee Letter and (ii) Regions Capital Markets, a division of Regions Bank, and the Administrative Agent, for their own respective accounts, any and all fees in such amounts and at such times to which the Borrower and Regions Capital Markets or the Administrative Agent, as applicable, shall reasonably agree. Except as otherwise reasonably agreed to by the Borrower and Regions Capital Markets or the

Administrative Agent, as applicable, such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

Section 2.09 Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance made by each Lender from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

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

(b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect from time to time, payable on the last day of such Interest Period, and in the case of six month Interest Periods, on the day which occurs during such Interest Period three months from the first day of such Interest Period.

(c) Default Rate. Notwithstanding the foregoing, (i) upon the occurrence and during the continuance of an Event of Default under Section 7.01(a) or 7.01(e), all Obligations shall bear interest, after as well as before judgment, at the Default Rate and (ii) upon the occurrence and during the continuance of any Event of Default (including under Section 7.01(a) or 7.01(e)), upon the request of the Majority Lenders, all Obligations shall bear interest, after as well as before judgment, at the Default Rate. Interest accrued pursuant to this Section 2.10(d) and all interest accrued but unpaid on or after the Maturity Date shall be due and payable on demand. Notwithstanding anything to the contrary contained in this Section, in no event shall the rate of interest accruing from and after the occurrence of an Event of Default exceed the maximum amount allowed by applicable law.

(d) Usury Recapture.

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

(ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Lender pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Lender the interest rates charged under Section 2.09 hereunder shall be retroactively increased such that the effective rate of interest under the Loan Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, the Borrower shall pay to such Lender the amount of the Lost Interest remaining to be recaptured by such Lender.

(iii) NOTWITHSTANDING the foregoing or any other term in this Agreement and the Loan Documents to the contrary,

it is the intention of each Lender and the Borrower to conform strictly to any applicable usury laws. Accordingly, if any Lender contracts for, charges, or receives any consideration which constitutes interest in excess of the Maximum Rate, then any such excess shall be canceled automatically and, if previously paid, shall at such Lender's option be applied to the outstanding 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 1:00 p.m. Jackson, Mississippi, 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; provided that, the Borrower may setoff amounts owing to any Lender that is at such time a Defaulting Lender against Advances that such Defaulting Lender failed to the fund to the Borrower under this Agreement (the "Unfunded Advances") so long as (i) the Borrower shall have delivered prior written notice of such setoff to the Administrative Agent and such Defaulting Lender, (ii) the Advances made by the Non-Defaulting Lenders as part of the original Borrowing to which the Unfunded Advances applied shall still be outstanding, (iii) if such Defaulting Lender failed to fund Advances under more than one Borrowing, such setoff shall be applied in a manner satisfactory to the Administrative Agent, and (iv) upon the application of such setoff, the Unfunded Advances shall be deemed to have been made by such Defaulting Lender on the effective date of such setoff. The Administrative Agent may charge, when due and payable, Borrower's Account for all interest, principal, fees and other amounts owing to the Administrative Agent, any Issuing Lender or any Lender on or with respect to this Agreement, the Advances or the Loan Documents. 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, an Issuing Lender, or a specific Lender pursuant to Section 2.08(a), 2.09(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 any 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, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error.

(c) Non‑Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the immediately 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(a), the setoff right of the Borrower under Section 2.10(a) above, or the non-pro rata application of payments provided in the last sentence of this Section 2.11), such Lender shall notify the Administrative Agent and forthwith purchase from the other Lenders such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender's ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.11 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set‑off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. If a Lender fails to fund an Advance with respect to a Borrowing as and when required hereunder and the Borrower subsequently makes a repayment of any Advances, then, after taking into account any setoffs made pursuant to Section 2.10(a) above, such payment shall be applied among the Non-Defaulting Lenders ratably in accordance with their respective Commitment percentages until each Lender (including any Lender that is at such time a Defaulting Lender) has its percentage of all of the outstanding Advances and the balance of such repayment shall be applied among the Lenders in accordance with their Applicable Percentage. 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. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:


(a)	any continuation, conversion, payment or prepayment (including any deemed payment or repayment and any reallocated repayment to Non-Defaulting Lenders provided for in Section 2.05(a) or Section 2.16) of any Advance other than a Reference Rate Advance on a day other than the last day of the

Interest Period for such Advance (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

(b) any failure by the Borrower (for a reason other than the failure of such Lender to make an Advance) to prepay, borrow, continue or convert any Advance other than a Reference Rate Advance on the date or in the amount notified by the Borrower; or

(c) any assignment of an Eurodollar Advance on a day other than the last day of the Interest Period therefor as a result of a request by the Borrower pursuant to Section 2.14;

including any loss of anticipated profits, any foreign exchange losses and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Advance, from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign exchange contract. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing. For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 2.12, the requesting Lender shall be deemed to have funded the Eurodollar Advances made by it at the Eurodollar Base Rate used in determining the Eurodollar Rate for such Advance by a matching deposit or other borrowing in the offshore interbank market for Dollars for a comparable amount and for a comparable period, whether or not such Eurodollar Advance was in fact so funded.

Section 2.13 Increased Costs.

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

(b) Capital Adequacy. If any Lender or any Issuing Lender determines in good faith that compliance with any applicable Legal Requirement or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), in each case which constitutes a Change in Law, affects or would affect the amount of capital required or expected to be maintained by such Lender or such Issuing Lender or any corporation controlling such Lender or such Issuing Lender and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend or such Issuing Lender's commitment to issue the Letters of Credit and other commitments of this type, then, within 30 days after receipt of the certificate required by this subsection (b) from such Lender or such Issuing Lender (with a copy of any such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender or to such Issuing Lender, as the case may be, from time to time as specified by such Lender or such Issuing Lender, additional amounts sufficient to compensate such Lender or such Issuing Lender, in light of such circumstances, (i) with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender's commitment to lend under this Agreement and (ii) with respect to such Issuing Lender, to the extent that such Issuing Lender reasonably

determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit. A certificate as to such amounts and detailing the calculation of such amounts submitted to the Borrower by such Lender or such Issuing Lender shall be conclusive and binding for all purposes, absent manifest error.

(c) Letters of Credit. If any change after the Closing Date in any applicable Legal Requirement or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, any Issuing Lender or (ii) impose on any 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 such Issuing Lender of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by such Issuing Lender's reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by such Issuing Lender, the Borrower shall pay to such Issuing Lender, from time to time as specified by such Issuing Lender, additional amounts which shall be sufficient to compensate such Issuing Lender for such increased cost. A certificate as to such increased cost incurred by such 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 such Issuing Lender to the Borrower, shall be conclusive and binding for all purposes, absent manifest error.

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 2.13 shall not constitute a waiver of such Lender's or the Issuing Bank's right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank 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 Bank, 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 Bank's intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 2.14 Taxes.

(a)

No Deduction for Certain Taxes. Any and all payments by the Borrower shall be made, in accordance with Section 2.10, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, each Issuing Lender, and the Administrative Agent, each of the following: (a) income or franchise taxes imposed on (or measured by) its net income by the United States of America or such other jurisdiction under the laws of which such recipient is organized or in which its principal office is located or, in the case of any Lender, in which its applicable lending office is located, (b) any branch profits taxes imposed by the United States of America or any similar tax imposed by any other jurisdiction in which the Borrower or any Guarantor is located, (c) in the case of a Foreign Lender (other than an assignee pursuant to a request by the Borrower under Section 2.15(a)), any withholding tax that is imposed by the United States of America on amounts payable to such Foreign Lender at the time such Foreign Lender becomes a party to this Agreement (or designates a new lending office) or is attributable to such Foreign Lender's failure to comply with Section 2.14(d), except to the extent that such Foreign Lender (or its assignor, if any) was entitled, at the time of designation of a new lending office (or assignment), to receive additional amounts with respect to such withholding tax pursuant to clauses (a) or (c) of this Section 2.14, and (d) any United States withholding tax that is imposed under FATCA. (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by applicable Legal Requirement to

deduct any Taxes from or in respect of any sum payable to any Lender, any Issuing Lender, or the Administrative Agent: (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.14), such Lender, such Issuing Lender, or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

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

(c) Indemnification. THE BORROWER INDEMNIFIES EACH LENDER, EACH ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING ANY TAXES OR OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.14) PAID BY SUCH LENDER, SUCH 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, ANY SUCH ISSUING LENDER, OR ANY SUCH LENDER. IF ANY LENDER, THE ADMINISTRATIVE AGENT, OR ANY ISSUING LENDER RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID BY THE BORROWER UNDER THIS PARAGRAPH (C), SUCH LENDER, THE ADMINISTRATIVE AGENT, OR SUCH ISSUING LENDER, AS THE CASE MAY BE, SHALL PROMPTLY PAY TO THE BORROWER THE BORROWER'S SHARE OF SUCH REFUND.

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

W8-BEN that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. If an event (including any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Lender from duly completing and delivering any such letter or form with respect to it and such Lender advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and in the case of a Form W‑8 or W‑9, establishing an exemption from United States backup withholding tax, such Lender shall not be required to deliver such letter or forms. The Borrower shall withhold tax at the rate and in the manner required by the laws of the United States with respect to payments made to a Lender failing to timely provide the requisite Internal Revenue Service forms. Notwithstanding the preceding Section 2.14(d), the completion, execution and submission of such documentation (other than the Form W-8 ECI, Form W-8 EN or Form W-9, respectfully) shall not be required if, in the Lender's reasonable judgment, such completion, execution or submission would subject any such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(e) FATCA. Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person, 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 clause (e), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Section 2.15 Mitigation Obligations; Replacement of Lenders.

(a) 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. A Lender shall not be required to make any such delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such delegation cease to apply.

(b) Replacement of Lenders. If (i) any Lender requests compensation under Section 2.13, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, (iii) any Lender suspends its obligation to continue, or Convert Advances into, Eurodollar Advances pursuant to Section 2.03(c)(ii) or Section 2.05(d), (iv) any Lender becomes a Defaulting Lender, or (v) any Lender refuses to consent to an amendment, modification or waiver of this Agreement that requires consent of 100% of the Lenders pursuant to

Section 9.01 and that has been approved by the Required Lenders (any such Lender described in any of the preceding clauses (i) - (iv), being a "Subject Lender"), then the Borrower may, at the Borrower's sole expense and effort and upon notice to such Subject Lender and the Administrative Agent and, in the case of a Defaulting Lender, the Administrative Agent may, upon notice to such Defaulting 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) provided that:

(i) other than for an assignment of a Defaulting Lender requested by the Administrative Agent, the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 9.06;

(ii) such Subject Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in 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 other than in the case of a Defaulting Lender) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.14, such assignment will result in a reduction in such compensation or payments thereafter;

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

(v) a Subject Lender shall not be required to make any such assignment if, prior thereto, as a result of a waiver by such Subject Lender or otherwise, the circumstances entitling the Borrower to require such assignment cease to apply.

Solely for purposes of effecting any assignment involving a Defaulting Lender under this Section 2.15(b) 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 is a Defaulting Lender and such Lender shall be bound thereby as fully and effectively as if such Lender had personally executed, acknowledged and delivered the same. In lieu of the Borrower or the Administrative Agent replacing a Defaulting Lender as provided in this Section 2.15(b), the Borrower may terminate such Defaulting Lender's applicable Commitment as provided in Section 2.04.

Section 2.16 Defaulting Lender Provisions.

(a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by Legal Requirement:

(i) Waivers and Amendments. Such Defaulting Lender's right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article 7 or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 7.04 shall be applied at such time or times as may be determined by Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Lender hereunder; third, on a pro rata basis, to Cash Collateralize the Issuing Lender's Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.07(h); fourth, as Borrower may request (so long as no Default or Event of Default exists), to the funding of any Advance in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender's potential future funding obligations with respect to Advances under this Agreement and (y) Cash Collateralize the Issuing Lender's future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.07(h); sixth, to the payment of any amounts owing to the Lenders or the Issuing Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Issuing Lender against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to Borrower as a result of any judgment of a court of competent jurisdiction obtained by Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Advances or Letter of Credit Obligations in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Advances were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and Letter of Credit Obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or Letter of Credit Obligations owed to, such Defaulting Lender until such time as all Advances and funded and unfunded participations in Letter of Credit Obligations are held by the Lenders pro rata in accordance with the Commitments under the Facility without giving effect to Section 2.16(a)(vi). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.16(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees.

(1) No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(2) No Defaulting Lender shall be entitled to receive letter of credit fees for any period during which that Lender is a Defaulting Lender, except to the extent allocable to its Applicable Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.07(h).

(3) With respect to any letter of credit fee not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender's participation in Letter of Credit Obligations that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to Issuing Lender, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to Issuing Lender's Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender's participation in the Letter of Credit Obligations shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to such Defaulting Lender's applicable Commitments) but only to the extent that (x) the conditions set forth in Section 3.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the sum of (1) the aggregate amount of Advances owing to such Non-Defaulting Lender, plus (2) such Non-Defaulting Lender's participation in Letters of Credit to exceed such Non-Defaulting Lender's Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender's increased exposure following such reallocation.

(v) Cash Collateral. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, within one Business Day, Cash Collateralize the Issuing Lender's Fronting Exposure in accordance with the procedures set forth in Section 2.07(h).

(vi) Defaulting Lender Cure. If the Borrower, Administrative Agent, and Issuing Lender agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Advances and funded and unfunded participations in Letters of Credit to be held pro rata by the applicable Lenders in accordance with the applicable Commitments under the Facility (without giving effect to Section 2.16(a)(iv), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender having been a Defaulting Lender.

Section 4.11 Taxes.

(a) Reports and Payments. All Returns (as defined below in clause (c) of this Section 4.11) required to be filed by or on behalf of the Borrower, the Guarantors, or any member of the Controlled Group (hereafter collectively called the "Tax Group") have been duly filed on a timely basis or appropriate extensions have been obtained, except where the failure to so file could not be reasonably expected to cause a Material Adverse Change; such Returns are complete and correct in all material respects; and all Taxes shown to be due and payable on the Returns or on subsequent assessments with respect thereto have been paid in full on a timely basis, and no other Taxes will be payable by the Tax Group with respect to items or periods covered by such Returns, except in each case to the extent of (i) reserves reflected in the Financial Statements 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, except for such Taxes or reserves therefor, the failure to pay or provide for which does not and could not reasonably be expected to cause a Material Adverse Change.

(b) Taxes Definition. "Taxes" in this Section 4.11 shall mean all taxes, charges, fees, levies, or other assessments imposed by any federal, state, local, or foreign taxing authority, including 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 or with respect to any such assessment).

(c) Returns Definition. "Returns" in this Section 4.11 shall mean any federal, state, local, or foreign report, declaration of estimated Tax, information statement or return relating to, or required to be filed in connection with, any Taxes, including any information return or report with respect to backup withholding or other payments of third parties.

Section 4.12 Pension Plans. All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan, and each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. No "accumulated funding deficiency" (as defined in Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of the Code. No Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects in accordance 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.

Section 4.13 Condition of Property; Casualties. Each of the Borrower and the Guarantors has good and defensible title to all of its material (individually and in the aggregate) Properties as is customary in the oil and gas industry in all material respects, free and clear of all Liens except for Permitted Liens. The Properties used or to be used in the continuing operations of the Borrower and each of the Guarantors are in good repair, working order and condition, except to the extent that the failure to be in such condition could not reasonably be expected to result in a Material Adverse Change. Since the date of the Financial Statements, neither the business nor any Property of the Borrower or any Guarantor has been 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 such adverse event could not reasonably be expected to cause a Material Adverse Change.

Section 4.14 No Defaults.

(a) Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any contract, agreement, lease, or other instrument to which the Borrower or any Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Change or under any agreement in connection with any Debt.

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

Section 4.18 Liens; Titles, Leases, Etc. None of the Property of the Borrower or any of the Guarantors is subject to any Lien other than Permitted Liens. On the Closing Date, all governmental actions and all other filings, recordings, registrations, third party consents and other actions which are necessary to perfect the Liens provided for in the Security Instruments will have been made, obtained and taken in all relevant jurisdictions or, with respect to any filings or recordings necessary to create and perfect such Liens, arrangements to do so shall have been made.

Section 5.02 Maintenance of Insurance.

(a) The Borrower shall, on behalf of itself and each of its Subsidiaries, procure and maintain or shall cause to be procured and maintained continuously in effect policies of insurance (after giving effect to any self-insurance compatible with the following standard) in form and amounts and issued by companies, associations or organizations reasonably satisfactory to the Administrative Agent covering such casualties, risks, perils, liabilities and other hazards reasonably required by the Administrative Agent. In addition, the Borrower shall, on behalf of itself and each of its Subsidiaries, comply with all requirements regarding insurance contained in the Security Instruments.

(b) Borrower shall furnish to Administrative Agent certified copies of policies or certificates thereof, and endorsements and renewals thereof for all such policies promptly upon request by the Administrative Agent. All Property insurance policies shall have attached thereto a Lender's loss payable endorsement for the benefit of the Administrative Agent, as loss payee in form reasonably satisfactory to the Administrative Agent and all liability insurance policies shall name the Administrative Agent as an additional insured. All policies or certificates of insurance shall set forth the coverage, the limits of liability, the name of the carrier, the policy number, and the period of coverage. In addition, all policies with respect to Property insurance required under the terms hereof shall contain an endorsement or agreement by the insurer that any loss shall be payable in accordance with the terms of such policy notwithstanding any act of negligence of the Borrower, or a Subsidiary or any party holding under the Borrower or a Subsidiary which might otherwise result in a forfeiture of the insurance and the further agreement of the insurer waiving all rights of setoff, counterclaim or deductions against the Borrower and its Subsidiaries.

ARTICLE VIII

THE ADMINISTRATIVE AGENT AND THE ISSUING LENDERS

Section 8.01 Authorization and Action. Each Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof and of the other Loan Documents, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement or any other Loan Document (including 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 which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, any other Loan Document, or applicable law.

Section 8.02 Administrative Agent's Reliance, Etc. Neither the Administrative Agent nor any of its Related Parties 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 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 EACH ISSUING LENDER AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE RELATED PARTIES (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 SUCH ISSUING LENDER IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY ACTION TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT OR SUCH ISSUING LENDER UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (INCLUDING THE ADMINISTRATIVE AGENT'S, SUCH ISSUING LENDER'S AND SUCH RELATED PARTY'S OWN NEGLIGENCE), AND INCLUDING ENVIRONMENTAL LIABILITIES, provided THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR DISBURSEMENTS RESULTING FROM THE ADMINISTRATIVE AGENT'S, SUCH ISSUING LENDER'S OR SUCH RELATED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE THE ADMINISTRATIVE AGENT AND EACH 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 SUCH ISSUING LENDER IS NOT REIMBURSED FOR SUCH BY THE BORROWER. To the extent that the indemnity obligations provided in this Section 8.05 are for the benefit of the Administrative Agent as the named secured party under the Liens granted under the Security Instruments, each Lender hereby agrees that if such Lender ceases to be a Lender hereunder but

Obligations owing to such Lender or an Affiliate of such Lender continue to be secured by such Liens, then such Lender shall continue to be bound by the provisions of this Section 8.05 until such time as such Obligations have been satisfied or terminated in full. 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 Lenders. The Administrative Agent or any Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders upon receipt of written notice from the Required Lenders to such effect. Any Issuing Lender designated in writing by the Borrower as provided in the definition of "Issuing Lender" may be removed at any time with or without cause by the Borrower. Upon receipt of notice of any such resignation or removal (other than a removal of an Issuing Lender by the Borrower), 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 $500,000,000.00 and, in the case of the Issuing Lender, a Lender. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Administrative Agent or Issuing Lender, and the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent's or Issuing Lender's resignation or removal hereunder as Administrative Agent or Issuing Lender, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Loan Documents.

Section 8.07 Additional Agents. Neither the Syndication Agent nor the Documentation Agent referred to on the cover of this Agreement shall have any duties, obligations or liabilities in their respective capacities as agents.

Section 8.08 Collateral Matters.

(a)

Administrative Agent is authorized on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any actions with respect to any Collateral or Security Instruments which may be necessary to perfect and maintain Acceptable Security Interests in and Liens upon the Collateral granted pursuant to the Security Instruments. Administrative Agent is further authorized on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any action (other than enforcement actions requiring the consent of, or request by, the Required Lenders as set forth in Section 7.02 or Section 7.03 above) in exigent circumstances as may be reasonably necessary to

preserve any rights or privileges of the Secured Parties under the Loan Documents or applicable law. By accepting the benefit of the Liens granted pursuant to the Security Instruments, each Secured Party not party hereto hereby agrees to the terms of this paragraph (a).

(b) Each Secured Party irrevocably authorizes Administrative Agent to release any Lien granted to or held by the Administrative Agent upon any Collateral: (i) upon termination of the Commitments, termination or expiration of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the applicable Issuing Lender have been made), and payment in full of all Obligations payable under this Agreement, under any other Loan Document and termination of all Hedge Contracts with any Swap Counterparty (other than Hedge Contracts with any Swap Counterparty with respect to which other arrangements satisfactory to the Swap Counterparty have been made; provided that, unless a Swap Counterparty notifies the Administrative Agent in writing at least 2 Business Days prior to the expected termination of the Commitments that such arrangements have not been made, then solely for purposes of this clause (b), it shall be deemed that such satisfactory arrangements have been made); (ii) constituting Property sold or to be sold or otherwise disposed of as part of or in connection with any disposition permitted under this Agreement or the other Loan Documents; (iii) constituting Property in which the Borrower or any Subsidiary owned no interest at the time the Lien was granted or at any time thereafter; (iv) constituting Property leased to the Borrower or any Subsidiary under a lease which has expired or has been terminated in a transaction permitted under this Agreement or is about to expire and which has not been, and is not intended by the Borrower or such Subsidiary to be, renewed or extended; or (v) if approved, authorized or ratified in writing by the applicable Required Lenders or all the Lenders, as the case may be, as required by Section 9.01. Upon the request of the Administrative Agent at any time, the Secured Parties will confirm in writing the Administrative Agent's authority to release particular types or items of Collateral pursuant to this Section 8.08. 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).

Section 9.03 No Waiver; Remedies. No failure on the part of any Lender, the Administrative Agent, or any Issuing Lender to exercise, and no delay in exercising, any right hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

Section 9.04 Costs and Expenses. The Borrower agrees to pay on demand (a) all reasonable out-of-pocket costs and expenses of the Administrative Agent in connection with the preparation, execution, waiver, delivery, administration, modification, and amendment of this Agreement, the Notes, the Guaranties, and the other Loan Documents including the reasonable fees and out‑of‑pocket expenses of counsel for the Administrative Agent with respect to advising the Administrative Agent as to its rights and responsibilities under this Agreement, and (b) all out‑of‑pocket costs and expenses, if any, of the Administrative Agent, each Issuing Lender, and each Lender (including reasonable counsel fees and expenses of the Administrative Agent, each Issuing Lender, and each Lender) in connection with the enforcement (whether through negotiations, legal proceedings, or otherwise) of this Agreement, the Notes, the Guaranties, and the other Loan Documents. Any sums spent by the Administrative Agent, any Issuing Lender and each Lender in payment of the foregoing costs and expenses shall become part of the Obligations and shall bear interest at an annual rate equal to the Default Rate from the date demanded until the date repaid by or on behalf of the Borrower.

Section 9.05 Binding Effect.

assign its rights or delegate its duties under this Agreement or any interest in this Agreement without the prior written consent of each Lender.

Section 9.06 Lender Assignments and Participations.

(a) Assignments. Any Lender may assign to one or more banks or other entities all or any portion of its rights and obligations under this Agreement (including all or a portion of its Commitments, the Advances owing to it, the Notes held by it, and the participation interest in the Letter of Credit Obligations held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of such Lender's rights and obligations assigned under this Agreement and shall be an equal percentage with respect to both its obligations owing in respect of the Commitments and the related Advances and Letters of Credit, (ii) the amount of the Commitments and Advances of such Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall be, if to an entity other than a Lender, not less than $3,000,000 and shall be an integral multiple of $1,000,000 in excess thereof, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with the Notes subject to such assignment, and (v) each Eligible Assignee (other than the Eligible Assignee of the Administrative Agent) shall pay to the Administrative Agent a $3,500 administrative fee (provided that the Administrative Agent may waive such fee). Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the execution thereof (unless the Administrative Agent agrees otherwise), (A) the assignee thereunder shall be a party hereto for all purposes and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (B) such Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of such Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.12, 2.13, 2.14, 9.04 and 9.07 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(b) Term of Assignments. By executing and delivering an Assignment and Acceptance, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency of value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or its Subsidiaries or the performance or observance by the Borrower or its Subsidiaries of any of their obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the Financial Statements referred to in Section 4.05 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such Lender 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; (v) such assignee 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, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

(c) The Register. The Administrative Agent shall maintain at its address referred to in Section 9.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amount of the Advances owing to, each Lender from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Administrative Agent, the Issuing Lenders, and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Procedures. Upon its receipt of an Assignment and Acceptance executed by a Lender and an Eligible Assignee, together with the Notes subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of the attached Exhibit A: (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the Borrower. Promptly after its receipt of such notice, the Borrower shall execute and deliver to the Administrative Agent in exchange for the surrendered Notes (A) if such Eligible Assignee has acquired a Commitment, a new Note to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and (B) if such Lender has retained any Commitment hereunder, a new Note to the order of such Lender in an amount equal to the Commitment retained by it hereunder. Such new Notes shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of the attached Exhibit E.

(e) Participations. Each Lender may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments, the Advances owing to it, its participation interest in the Letter of Credit Obligations, and the Notes held by it); provided, however, that (i) such Lender's obligations under this Agreement (including its Commitments to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Notes for all purposes of this Agreement, (iv) the Borrower, the Administrative Agent, and the Issuing Lenders and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement, and (v) such Lender shall not require the participant's consent to any matter under this Agreement, except for change in the principal amount of the Notes, reductions in fees or interest, releasing all or substantially all of any Collateral, permitting the Borrower or any Subsidiary to enter into any merger or consolidation with or into any other, postponement of any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable hereunder, or extensions of the Maturity Date or the Commitment Termination Date. The Borrower hereby agrees that participants shall have the same rights under Sections 2.12, 2.13, 2.14(c), and 9.07 as a Lender to the extent of their respective participations. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 7.04 as though it were a Lender, provided such Participant agrees to be subject to Section 2.11 as though it were a Lender.

Each Lender that sells a participation shall, acting solely for this purpose as non-fiduciary agent of the Borrower, maintain a register in the United States on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the obligations under the Loan Documents (the “Participant Register”) and no Lender shall have any obligation to disclose any information contained in any Participant Registry (including the identity of any Participant or any information relating to the Participant's interests under this Agreement) except to the extent that such disclosure is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. Borrower hereby agrees that each Lender acting as its non-fiduciary agent solely for the purpose set forth above in this clause (e), shall not subject such Lender to any fiduciary or other implied duties, all of which are hereby waived by Borrower.

(f) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 2.13 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.14 unless such Participant and such Participant agrees, for the benefit of such Borrower, to comply with Section 2.14(d), in which case Section 2.14 shall be applied as if such Participant had become a Lender and had acquired its interest by assignment pursuant to paragraph (a) of this Section; provided that, in no event shall such Participant be entitled to receive any greater payment under Section 2.14 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant.

(g) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(h) Any Lender may furnish any information concerning the Borrower or any of its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants), subject, however, to the provisions of the following paragraph Section 9.13.

Section 9.07 Indemnification; Waiver of Damages.

(a) THE BORROWER agrees to, JOINTLY AND SEVERALLY, indemnify and hold harmless EACH LENDER PARTY AND EACH RELATED PARTY OF A lENDER pARTY (each, an "Indemnitee") from and against any and all claims, damages, losses, liabilities, costs, and expenses (including, without limitation, reasonable attorneys' fees) that may be incurred by or asserted or awarded against any Indemnitee, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation, or proceeding or preparation of defense in connection therewith) the LOAN Documents, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances, in all cases, whether or not caused by or arising, in whole or in part, out of the comparative,

contributory or sole negligence OR THE STRICT LIABILITY of the applicable INDEMNITEE, except to the extent such claim, damage, loss, liability, cost, or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnitee's gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 9.07 applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by BORROWER, its directors, shareholders or creditors, any GUARANTOR, its directors, shareholders or creditors or an Indemnitee or any other Person or any Indemnitee is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. THE FOREGOING INDEMNITY AND HOLD HARMLESS SHALL NOT APPLY TO ANY CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS OR EXPENSES THAT is INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNITEE directly FOR, OR AS A direct CONSEQUENCE OF, SUCH INDEMNITEE BEING A DEFAULTING LENDER under clause (a) or (b) of the definition of "Defaulting Lender", WHETHER ASSERTED BY BORROWER, ANY GUARANTOR, THE ADMINISTRATIVE AGENT OR THE ISSUING LENDER. You shall not, without the prior written consent of each Indemnitee 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 Indemnitee to claim indemnification hereunder unless such settlement (x) includes a full and unconditional release of all liabilities arising out of such claim or action against such Indemnitee, (y) does not include any statement as to or an admission of fault, culpability or failure to act by or on behalf of any Indemnitee, and (z) does not impose any actual or potential liability upon such Indemnitee. All amounts due under this Section 9.07 shall be payable not later than 10 days after demand therefor.

(b) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, each of the Borrower and any Guarantor shall not assert, agrees not to assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Advance or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in subsection (a) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed to such unintended recipients by such Indemnitee 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 other than for direct or actual damages resulting from the gross negligence or willful misconduct of such Indemnitee as determined by a final and nonappealable judgment of a court of competent jurisdiction.

Section 9.08 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Section 9.09 Survival of Representations, Etc. All representations and warranties contained in this Agreement or made in writing by or on behalf of the Borrower in connection herewith shall survive the execution and delivery of this Agreement and the Loan Documents, the making of the Advances and any investigation made by or on behalf of the Lenders, none of which investigations shall diminish any Lender's right to rely on such representations and warranties. All obligations of the Borrower provided for in Sections 2.12, 2.13, 2.14(c), 9.04, and 9.07 and all of the obligations of the Lenders in Section 8.05 shall survive any termination of this Agreement and repayment in full of the Obligations.

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

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

Section 9.12 Governing Law; Submission to Jurisdiction.

(a) This Agreement, the Notes and the other Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Xxx. Art. 0000, Xx. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect. Each Letter of Credit shall be governed by either the Uniform Customs and Practice for Documentary Credits, International Chamber of Commerce Publication No. 600 (2007 version) or the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590 (and any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the applicable Issuing Lender).

(b) The Borrower hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Houston, Texas, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, and the Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court. The Borrower hereby unconditionally and irrevocably waives, to the fullest extent it may effectively do so, any right it may have to the defense of an inconvenient forum to the maintenance of such action or proceeding. The Borrower hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action or proceeding may be made by mailing or delivering a copy of such process to such Borrower at its address set forth in this Agreement. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section shall affect the rights of any Lender to serve legal process in any other manner permitted by the law or affect the right of any Lender to bring any action or proceeding against the Borrower or its Property in the courts of any other jurisdiction.

Section 9.13 Confidentiality. In the event that the Borrower or any of its Subsidiaries provides to the Administrative Agent or the Lenders confidential information belonging to the Borrower or such Subsidiary, which the Borrower or any Subsidiary shall designate in writing as "confidential", the Administrative Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the usual care that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Administrative Agent or the Lenders breaching their obligation of confidence to the Borrower, (iii) are previously known by the Administrative Agent or the Lenders from some source other than the Borrower, (iv) are hereafter developed by the Administrative Agent or the Lenders without using the Borrower's information, (v) are hereafter obtained by or available to the Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower's or such Subsidiary's consent, (vii) must be disclosed either pursuant to any Legal Requirement or to Persons regulating the activities of the Administrative Agent or the Lenders, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Administrative Agent or a Lender may disclose any such information to any other Lender, any Affiliate of any Lender, any independent petroleum engineers or consultants, any independent certified public accountants, any legal counsel employed by such Person in connection with this Agreement or any Security Instrument, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the date the information was furnished, unless the Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period. The Borrower and each of its Subsidiaries waives any and all other rights it may have to confidentiality as against the Administrative Agent and the Lenders arising by contract, agreement, statute or law except as expressly stated in this Section 9.13.

Section 9.14 Restatement. This Agreement amends and restates the Existing Agreement in its entirety. The Borrower hereby agrees that (a) the Debt outstanding under the Existing Agreement and the Loan Documents (as defined in the Existing Agreement; together with the Existing Agreement, the "Existing Loan Documents") and all accrued and unpaid interest thereon and (b) all accrued and unpaid fees under the Existing Loan Documents shall be deemed to be outstanding under and governed by this Agreement. The Borrower hereby acknowledges, warrants, represents and agrees that this Agreement is not intended to be, and shall not be deemed or construed to be, a novation or release of the Existing Loan Documents. Each Lender (which is a Lender under the Existing Loan Documents) hereby waives any requirements for notice of prepayment, minimum amounts of prepayments of the loans thereunder, ratable reductions of the commitments of Lenders under the Existing Loan Documents and ratable payments on account of the principal or interest of any loan under the Existing Loan Documents to the extent that any such prepayment, reductions or payments are required to ensure that, upon the effectiveness of this Agreement, the loans of the Lenders shall be outstanding on a ratable basis in accordance with their respective Pro Rata Share. Each Lender hereby authorizes the Administrative Agent and the Borrower to request Borrowings from the Lenders, to make prepayment of the loans under the Existing Loan Documents and to reduce the commitments under the Existing Loan Documents among Lenders in order to ensure that, upon the effectiveness of this Agreement, the Credit Extensions of the Lenders shall be outstanding on a ratable basis in accordance with their respective Pro Rata Share.

L. 107-56 (signed into law October 26, 2001)) (the "Act"), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act.
