35

date thereof, the Effective Amount would exceed the Aggregate Commitment or Borrowing Base then in effect.  Once reduced in accordance with this Section 2.4, neither the Maximum Loan Amount nor the Aggregate Commitment may be increased.  Any reduction of the Maximum Loan Amount or the Aggregate Commitment shall be applied to the respective Maximum Loan Amount of each Lender and Commitment of each Lender according to its Pro Rata Share.  All accrued commitment fees to, but not including, the effective date of any reduction or termination of the Maximum Loan Amount or the Aggregate Commitment, shall be paid on the effective date of such reduction or termination.

Section 2.5             Optional Prepayments.  Subject to Section 3.4, the Company may, at any time or from time to time,

(a)           prepay Base Rate Loans upon same-day irrevocable notice to the Administrative Agent, ratably as to each Lender, in whole or in part, in aggregate minimum principal amounts of $100,000 or integral multiples thereof (unless the Effective Amount is less than $500,000, then such prepayments shall be equal to the Effective Amount); and

(b)           prepay LIBO Rate Loans upon irrevocable notice to the Administrative Agent not less than three (3) Business Days, ratably as to each Lender, in whole or in part, in aggregate minimum principal amounts of $500,000 or integral multiples thereof plus all interest and expenses then outstanding on such LIBO Rate Loans.

Such notice of prepayment shall specify the date and amount of such prepayment and the Interest Rate Type(s) of Loans to be prepaid.

The Administrative Agent will promptly notify each Lender of its receipt of any such notice, and of such Lender’s Pro Rata Share of such prepayment.  The payment amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to each such date on the amount prepaid and any amounts required pursuant to Section 3.4.

Section 2.6             Borrowing Base Determinations, Mandatory Prepayments.

(a)           Scheduled Borrowing Base Determinations.  For the period from the Effective Date to the initial redetermination date pursuant to Section 2.6(c) or Section 2.6(d), the initial Borrowing Base hereunder shall be $175,000,000 (the “Initial Borrowing Base”).

(b)           Annual Borrowing Base Determinations.  Upon receipt by the Administrative Agent of each Reserve Report described in Section 7.2(c)(i), the Administrative Agent shall make a determination by May 1, or, if later, within 25 days of the receipt of such report (such determination, the “Annual Proposed Borrowing Base”) of the amount of the borrowing base (herein as determined and redetermined from time to time and in effect on any date called the “Borrowing Base”) on account of such reserves as of the preceding January 1, subject to the approval of all of the Lenders other than the Defaulting Lenders, if any, or the Supermajority Lenders (as applicable) as provided in this Section 2.6(b), and the Administrative Agent shall promptly notify the Lenders in writing of the Annual Proposed Borrowing Base once determined.  The Annual Proposed Borrowing Base shall be so made by the Administrative Agent in accordance with the Administrative Agent’s normal and customary practices and

36

standards for oil and gas loans (including consideration of the Company’s liquidity, Derivative Contracts, market interest rates, commodity prices, permitted Indebtedness, capital expenditure requirements and the First Lien Cap (as defined in the Intercreditor Agreement)).  Any Annual Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by all of the Lenders other than the Defaulting Lenders, if any, and any Annual Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or deemed to have been approved by the Supermajority Lenders, in each case as provided in this Section 2.6(b).  The Lenders other than the Defaulting Lenders, if any, or the Supermajority Lenders (as applicable) may approve the Annual Proposed Borrowing Base by written notice to the Administrative Agent within 15 days of the Administrative Agent’s notice of the Annual Proposed Borrowing Base.  Any Lender that fails to respond to any notice of the Annual Proposed Borrowing Base by the Administrative Agent pursuant to this Section 2.6(b) within such 15 days shall be deemed to have approved such Annual Proposed Borrowing Base.  If the Lenders other than the Defaulting Lenders, if any, or the Supermajority Lenders (as applicable) fail to approve the Annual Proposed Borrowing Base within such 15 days, then no later than five days after the end of such 15-day period, the Lenders shall submit to the Administrative Agent in writing, or the Administrative Agent shall poll the Lenders other than the Defaulting Lenders, if any, for, their individual recommendations for the redetermined Borrowing Base in accordance with their respective normal and customary practices and standards for oil and gas loans (including consideration of the Company’s liquidity, Derivative Contracts, market interest rates, commodity prices, permitted Indebtedness, capital expenditure requirements and the First Lien Cap (as defined in the Intercreditor Agreement)), whereupon the Administrative Agent shall designate the Borrowing Base at the largest amount approved by the Lenders other than the Defaulting Lenders, if any, or the Supermajority Lenders (as applicable); provided, however, that it is expressly understood that the Lenders and Administrative Agent have no obligation to agree upon or designate the Borrowing Base at any particular amount.  If any Lender refuses to accept an Annual Proposed Borrowing Base pursuant to this Section 2.6(b), the Company shall have the right, without the consent of the Lenders but with the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, to cause the Commitment of such dissenting Lender to be replaced pursuant to Section 3.7.

(c)           Semi-Annual Borrowing Base Determinations.  In addition, upon the receipt by the Administrative Agent of each Reserve Report described in Section 7.2(c)(ii), the Administrative Agent shall make a determination by November 1, or, if later, within 25 days of the receipt of such report (such determination, the “Semi-Annual Proposed Borrowing Base”) of the Borrowing Base as of the preceding July 1.  The Semi-Annual Proposed Borrowing Base shall be determined in the same manner and be subject to the same approvals as prescribed with respect to the Annual Proposed Borrowing Base set forth in Section 2.6(b), and likewise the Administrative Agent shall notify the Lenders in writing of the Semi-Annual Proposed Borrowing Base once determined.  The Lenders other than the Defaulting Lenders, if any, or the Supermajority Lenders (as applicable) may approve the Semi-Annual Proposed Borrowing Base by written notice to the Administrative Agent within 15 days of the Administrative Agent’s notice of the Semi-Annual Proposed Borrowing Base.  Any Lender that fails to respond to any notice of the Semi-Annual Proposed Borrowing Base by the Administrative Agent pursuant to this Section 2.6(c) within such 15 days shall be deemed to have approved such Semi-Annual Proposed Borrowing Base.  If the Lenders other than the Defaulting Lenders, if any, or the

37

Supermajority Lenders (as applicable) fail to approve the Semi-Annual Proposed Borrowing Base within such 15 days, then no later than five days after the end of such 15-day period, the Lenders shall submit to the Administrative Agent in writing, or the Administrative Agent shall poll the Lenders other than the Defaulting Lenders, if any, for, their individual recommendations for the redetermined Borrowing Base in accordance with their respective normal and customary practices and standards for oil and gas loans (including consideration of the Company’s liquidity, Derivative Contracts, market interest rates, commodity prices, permitted Indebtedness, capital expenditure requirements and the First Lien Cap (as defined in the Intercreditor Agreement)), whereupon the Administrative Agent shall designate the Borrowing Base at the largest amount approved by the Lenders other than the Defaulting Lenders, if any, or the Supermajority Lenders (as applicable); provided, however, that it is expressly understood that the Lenders and Administrative Agent have no obligation to agree upon or designate the Borrowing Base at any particular amount.  If any Lender refuses to accept the Semi-Annual Proposed Borrowing Base pursuant to this Section 2.6(c), the Company shall have the right, without the consent of the Lenders but with the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, to cause the Commitment of such dissenting Lender to be replaced pursuant to Section 3.7.

(d)           Other Determinations.  In addition, the Administrative Agent shall, in the normal course of business following a request of the Company, redetermine the Borrowing Base (in the same manner and subject to the same approvals as prescribed in Section 2.6(b) for the redetermination of the Borrowing Base); provided, however, (i) the Administrative Agent and the Lenders shall not be obligated to respond to more than one such request during any calendar year in addition to each scheduled annual and semi-annual redeterminations provided for above, and (ii) the Company shall have paid to the Administrative Agent a $20,000 engineering fee in connection with such requested redetermination of the Borrowing Base, regardless of whether or not such redetermination results in any increase to the Borrowing Base.  Notwithstanding the foregoing, the Administrative Agent may, at the request of the Supermajority Lenders, redetermine the Borrowing Base (in the same manner and subject to the same approvals as prescribed in Section 2.6(b) for the redetermination of the Borrowing Base) at any other time and from time to time; provided, however, the Administrative Agent and the Lenders may not redetermine the Borrowing Base under this second sentence of this Section 2.6(d) more than one time during any calendar year, subject to the terms of Section 2.6(g).

(e)           Lenders’ Discretion.  If the Company does not furnish the Reserve Reports or all such other information and data by the date required, the Required Lenders together with the Administrative Agent may nonetheless determine a new Borrowing Base.  It is expressly understood that the Lenders shall have no obligation to determine the Borrowing Base at any particular amount, either in relation to the Maximum Loan Amount, the Aggregate Commitment or otherwise.  Furthermore, the Company acknowledges that the Lenders have no obligation to increase the Borrowing Base and may reduce the Borrowing Base in accordance with the terms of this Agreement, and that any increase in the Borrowing Base is subject to the credit approval processes of all of the Lenders (other than Defaulting Lenders) subject to the terms hereof.

38

(f)            Mandatory Action.

(i)            If on any date a Borrowing Base Deficiency exists, then the Company shall cure such Borrowing Base Deficiency immediately by prepaying the Loans in an aggregate principal amount equal to such excess, together with interest on the principal amount paid and accrued to date of such prepayment and if any excess remains after prepaying the Loans because of any Letter of Credit Outstandings, Cash Collateralize an amount equal to such excess; provided, however, that upon any Borrowing Base Deficiency caused by a redetermination downward of the Borrowing Base pursuant to Section 2.6, the Company may effect such cure through any of the following means or any combination thereof:  (A) the making of a lump sum principal prepayment on the Loans within 30 days of the occurrence of such Borrowing Base Deficiency (and, if any Borrowing Base Deficiency remains after prepayment of all Loans, Cash Collateralizing the Letter of Credit Outstandings to the extent required to eliminate the Borrowing Base Deficiency); (B) the making of a principal prepayment on the Loans (and, if any Borrowing Base Deficiency remains after prepayment of all Loans, Cash Collateralizing the Letter of Credit Outstandings to the extent required to eliminate the Borrowing Base Deficiency) in six substantially equal monthly installments commencing 30 days from the date the Borrowing Base Deficiency occurs and continuing on the same day of the next five succeeding months thereafter; or (C) the pledge within 15 Business Days of the occurrence of such Borrowing Base Deficiency of additional unencumbered Collateral of sufficient value and character (as determined by the Lenders in their sole discretion) that when added to the Borrowing Base shall equal the applicable Effective Amount.

(ii)      Notwithstanding the foregoing paragraph (i), upon any reduction to the Borrowing Base provided for in Section 8.2(f), if a Borrowing Base Deficiency shall exist or the Company or any Restricted Subsidiary shall have incurred any early termination or similar payment Obligation(s) to any Qualifying Derivative Contract Counterparty as a result of the Disposition and termination or modification of any related Derivative Contract(s), the Company shall contemporaneously with such Disposition (x) make, or cause to be made, a principal prepayment on the Loans in an amount equal to the Borrowing Base Deficiency and (y) satisfy in full all such Obligation(s) to any affected Qualifying Derivative Contract Counterparty.

(iii)     Unless the Required Lenders together with the Administrative Agent shall otherwise agree, if the Company or any of its Subsidiaries shall receive Net Cash Proceeds from any Disposition described in Section 8.2(f) or Recovery Event (A) during the continuance of an Event of Default, the Company shall cause the Loans to be prepaid or the outstanding Letters of Credit Cash Collateralized (at 105% of their respective face amounts) in an amount equal to the entirety of such Net Cash Proceeds and (B) except as provided in Section 2.6(f)(ii) and Section 8.9, so long as no Event of Default or Borrowing Base Deficiency exists or is continuing, the Company shall apply such proceeds in accordance with the Second Lien Term Loan Agreement to the extent required thereby.  The provisions of this Section 2.6(f)(iii) do not constitute a consent to the consummation of any Disposition not permitted by Section 8.2(f) or otherwise requiring the prior written consent of the Required Lenders and the Administrative Agent.

39

(g)           Reduction of Borrowing Base Related to Derivative Contracts.  If during any Borrowing Base Period the Company liquidates, unwinds, restructures or otherwise modifies any one or more Derivative Contracts in one or more transactions which the Administrative Agent considered in determining the then-effective Borrowing Base, and the value attributable to such liquidated, unwound, restructured or modified Derivative Contract, as calculated by the Administrative Agent in the then-effective Borrowing Base, in the aggregate exceeds 5% of such Borrowing Base, then the Company shall promptly provide notice to the Administrative Agent after such transaction or transactions and at the request of the Required Lenders, the Administrative Agent shall redetermine the Borrowing Base solely to take into account the value assigned to all such liquidated Derivative Contracts in the then-effective Borrowing Base.  Any such redetermination shall be in addition to the Lenders’ right to request an optional redetermination pursuant to Section 2.6(d).

Section 2.7             Repayment.

(a)           Principal.  The Company shall repay to the Administrative Agent for the benefit of the Lenders the outstanding principal balance of the Loans (and the outstanding principal of the Loans shall be due and payable) on the Termination Date.

(b)           Interest.  (i)  Each Loan shall bear interest on the principal amount thereof from the applicable Borrowing Date or date of conversion or continuation pursuant to Section 2.3, as the case may be, at a rate per annum equal to (A) in the case of LIBO Rate Loans the lesser of (x) the LIBO Rate plus the Applicable Margin and (y) the Highest Lawful Rate and (B) in the case of Base Rate Loans the lesser of (x) the Alternate Base Rate plus the Applicable Margin and (y) the Highest Lawful Rate.

(ii)           Interest on each Loan shall be paid in arrears on each Interest Payment Date.  Interest shall also be paid on the date of any prepayment of Loans under Sections 2.5(b) or 2.6 for the portion of the Loans so prepaid and upon payment (including prepayment) in full thereof and, during the existence of any Event of Default, interest shall be paid on demand of the Administrative Agent.

(iii)          Notwithstanding paragraph (i) of this Section 2.7(b), while any Event of Default exists or after acceleration, the Company shall pay interest (after as well as before entry of judgment thereon to the extent permitted by law) on the principal amount of all outstanding Loans, at a rate per annum equal to the lesser of (A) the Highest Lawful Rate and (B) the rate otherwise applicable plus two percent (2%) (“Default Rate”).

(iv)          During the period of any Borrowing Base Deficiency, unless the Default Rate is then in effect, the Company shall pay interest at a rate per annum equal to the lesser of (A) (i) the Alternate Base Rate plus 2.75% per annum or (ii) the LIBO Rate plus 3.75% per annum and (B) the Highest Lawful Rate.

Section 2.8             Fees.

(a)           Commitment Fees.  The Company shall pay to the Administrative Agent for the account of the Lenders an aggregate commitment fee on the actual daily amount of the Available Borrowing Base at a per annum rate equal to the amount set forth on the Pricing Grid.

40

Such commitment fee shall accrue from the Effective Time to the Termination Date and shall be due and payable quarterly in arrears on the first day of the month following the last Business Day of each quarter commencing with the quarter ended December 31, 2012 (and payable on January 1, 2013) through the Termination Date, with the final payment to be made on the Termination Date; provided, however, that in connection with any reduction or termination of the Maximum Loan Amount or Aggregate Commitment under Section 2.4, the accrued commitment fee calculated for the period ending on such date shall also be paid on the date of such reduction or termination, with the following quarterly payment being calculated on the basis of the period from such reduction or termination date to such quarterly payment date.  The commitment fees provided in this Section 2.8(a) shall accrue at all times after the Effective Time, up to the Termination Date including at any time during which one or more conditions in Article V are not met.

(b)           Letter of Credit Fees.  The Company agrees to pay (i) to the Administrative Agent for the account of the Lenders a Letter of Credit fee for each Letter of Credit, due and payable quarterly on the first day of the month following the last Business Day of each quarter and on the Termination Date, in arrears from the date of Issuance in an amount per annum equal to the product equal to the Letter of Credit Rate set forth on the Pricing Grid multiplied by the aggregate amount available under each Letter of Credit, on each day from the date of Issuance thereof to the date on which such Letter of Credit expires or is terminated, (ii) to the Issuing Lender for its account a fee, due and payable quarterly on the first day of the month following the last Business Day of each quarter and on the Termination Date, for the Issuance by it of each Letter of Credit in an amount per annum (calculated on the basis of a year of 360 days) equal to 0.00125 multiplied by the aggregate amount available under each Letter of Credit, on each day from the date of Issuance thereof to the date on which such Letter of Credit expires or is terminated and (iii) to the Issuing Lender, for its account on demand its customary letter of credit transactional fees and out-of-pocket expenses for each Letter of Credit Issued by it, including amendment fees, payable with respect to each such Letter of Credit.  The Administrative Agent shall pay to each Lender its pro-rata share of the Letter of Credit fees paid pursuant to this Section 2.8(b)(i).  The Administrative Agent shall pay to the Issuing Lender the Letter of Credit fees paid pursuant to this Section 2.8(b)(ii) and 2.8(b)(iii).

(c)           Other Fees.  In addition to all other amounts due to the Administrative Agent under the Loan Documents, the Company will pay fees to the parties and in the amounts specified in the Agent Fee Letter.

Section 2.9             Computation of Fees and Interest.  (a)  All computations of interest for Base Rate Loans when the Alternate Base Rate is based on the prime rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed.  All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more interest being paid than if computed on the basis of a 365 day year).  Interest and fees shall accrue during each period during which interest or such fees are computed from the first day thereof to but not including the last day thereof.

(b)           Each determination of an interest rate by the Administrative Agent shall be conclusive and binding on the Company and the Lenders in the absence of manifest error.

41

Section 2.10           Payments by the Company; Borrowings Pro Rata.  (a)  All payments to be made by the Company shall be made without setoff, recoupment or counterclaim.  Except as otherwise expressly provided herein, all payments by the Company shall be made to the Administrative Agent for the account of the Lenders at the Agent’s Payment Office, and shall be made in dollars and in immediately available funds, no later than 1:00 p.m. (New York, NY time) on the date specified herein.  Except to the extent otherwise expressly provided herein, (i) each payment by the Company of fees shall be made for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, (ii) each payment of principal of Loans shall be made for the account of the Lenders ratably in accordance with their respective Pro Rata Share of the outstanding principal amount of such Loans, and (iii) each payment of interest on Loans shall be made for the account of the Lenders ratably in accordance with their respective Pro Rata Share of the aggregate amount of interest due and payable to the Lenders.  The Administrative Agent will promptly distribute to each Lender its applicable share of such payment in like funds as received.  Any payment received by the Administrative Agent later than 1:00 p.m. (New York, NY time) shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue.

(b)           (Reserved).

(c)           Subject to the provisions set forth in the definition of “Interest Period” herein, whenever any payment is due on a day other than a Business Day, such payment shall be made on the following Business Day, and such extension of time shall in such case be included in the computation of interest or fees, as the case may be.

(d)           Unless the Administrative Agent receives notice from the Company prior to the date on which any payment is due to the Lenders that the Company will not make such payment in full as and when required, the Administrative Agent may assume that the Company has made such payment in full to the Administrative Agent on such date in immediately available funds and the Administrative Agent may (but shall not be so required), in reliance upon such assumption, distribute to each Lender on such due date an amount equal to the amount then due such Lender.  If and to the extent the Company has not made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent on demand such amount distributed to such Lender, together with interest thereon at the Federal Funds Rate for each day from the date such amount is distributed to such Lender until the date repaid.

(e)           Except to the extent otherwise expressly provided herein, each Borrowing hereunder shall be from the Lenders pro rata in accordance with their respective Pro Rata Shares.

Section 2.11           Funding by Lenders; Presumption by Administrative Agent.  (a)  Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.3 and may, in reliance upon such assumption, make available to the Company a corresponding amount.  In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Company severally agree to pay to the

42

Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Company to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, and (ii) in the case of a payment to be made by the Company, the interest rate applicable to Base Rate Loans.  If the Company and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Company the amount of such interest paid by the Company for such period.  If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Borrowing.  Any payment by the Company shall be without prejudice to any claim the Company may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(b)           Payments by Company; Presumptions by Administrative Agent.  Unless the Administrative Agent shall have received notice from the Company prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Lenders hereunder that the Company will not make such payment, the Administrative Agent may assume that the Company has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Lenders, as the case may be, the amount due.  In such event, if the Company has not in fact made such payment, then each of the Lenders or the Issuing Lenders, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Lender, with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(c)           The existence of a Defaulting Lender or the failure of any Lender to make any Loan on any Borrowing Date shall not relieve any other Lender of any obligation hereunder to make a Loan on such Borrowing Date, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on any Borrowing Date.

Section 2.12           Sharing of Payments, etc.  If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its Pro Rata Share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that:

43

(a)           if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(b)           the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Company pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in Letter of Credit Outstandings to any assignee or participant, other than to the Company or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

The Company agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of setoff, but subject to Section 11.8) with respect to such participation as fully as if such Lender were the direct creditor of the Company in the amount of such participation.  The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section 2.12 and will in each case notify the Lenders following any such purchases or repayments.

Section 2.13           Issuing the Letters of Credit.  (a)  In order to effect the issuance of a Letter of Credit, the Company shall submit a Notice of Borrowing and LC Application in writing by telecopy to the Administrative Agent (who shall promptly notify the Issuing Lender) not later than 1:00 p.m. (New York, NY time) three (3) Business Days before the requested date of issuance of such Letter of Credit.  Each such Notice of Borrowing and LC Application shall be signed by the Company, specify the Business Day on which such Letter of Credit is to be issued, the purpose for the requested Letter of Credit, specify the availability for Letters of Credit under the Borrowing Base, the Aggregate Commitment and the $15,000,000 aggregate Letter of Credit Outstandings limitation as of the date of issuance of such Letter of Credit and the expiry date thereof which shall not be later than the earlier of (i) one year after its Issuance (or, if renewed, one year after the renewal date) and (ii) the Maturity Date, unless such Letter of Credit has been Cash Collateralized with cash in an amount at least equal to 105% of the undrawn face amount thereof at least 30 days before the Maturity Date.  If requested by the Company not later than three (3) Business Days prior to expiration of any Letter of Credit, any Letter of Credit may be renewed for the additional period specified in Section 2.1(c).

(b)           Upon satisfaction of the applicable terms and conditions set forth in Article V, the Issuing Lender shall issue such Letter of Credit to the specified beneficiary not later than the close of business, New York, NY time, on the date so specified.  The Administrative Agent shall provide the Company and each Lender with a copy of each Letter of Credit so issued.  Each such Letter of Credit shall (i) provide for the payment of drafts, presented for honor thereunder by the beneficiary in accordance with the terms thereon, at sight when accompanied by the documents described therein and (ii) (A) the Uniform Customs and Practice for Documentary Credits (2007 Revision) (the “UCP”), International Chamber of Commerce Publication No. 600 or (B) the International Standby Practices (ISP98) (the “ISP”), 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

44

the Issuing Lender and shall, as to matters not governed by the UCP or ISP, be governed by, and construed and interpreted in accordance with, the laws of the State of New York.

(c)           Upon the Issuance of each Letter of Credit, the Issuing Lender shall be deemed, without further action by any party hereto, to have sold to each other Lender, and each other Lender shall be deemed, without further action by any party hereto, to have purchased from the Issuing Lender, a participation, to the extent of such Lender’s Pro Rata Share, in such Letter of Credit, the obligations thereunder and in the reimbursement obligations of the Company due in respect of drawings made under such Letter of Credit.  If requested by the Issuing Lender, the other Lenders will execute any other documents reasonably requested by the Issuing Lender to evidence the purchase of such participation.

(d)           Upon the presentment of any draft for honor under any Letter of Credit by the beneficiary thereof which the Issuing Lender determines is in compliance with the conditions for payment thereunder, the Issuing Lender shall promptly notify the Company, the Administrative Agent and each Lender of the intended date of honor of such draft and the Company hereby promises and agrees, at the Company’s option, to either (i) pay to the Administrative Agent for the account of the Issuing Lender the full amount of such draft in immediately available funds, by (x) 3:00 p.m. (New York, NY time) on the intended date of honor of such draft, if the Company received such notice on or prior to 10:00 a.m. (New York, NY time) on the intended date of honor of such draft or (y) if the Company shall have received such notice after 10:00 a.m. (New York, NY time) on the intended date of honor of such draft, then not later 3:00 p.m. (New York, NY time) on the first Business Day immediately following such intended date of honor of such draft or (ii) request a Loan pursuant to the provisions of Sections 2.1(a) and 2.2 of this Agreement in the full amount of such draft, which request shall specify that the Borrowing Date is to be the date payment is due under the Letter of Credit as specified in the Issuing Lender’s notice.  If the Company fails timely to make such payment because a Loan cannot be made pursuant to Section 2.1(a) or Section 5.2, each Lender shall, notwithstanding any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of Default), make available to the Administrative Agent for the benefit of the Issuing Lender an amount equal to its Pro Rata Share of the presented draft on the day the Issuing Lender is required to honor such draft.  If such amount is not in fact made available to the Administrative Agent by such Lender on such date, such Lender shall pay to the Administrative Agent for the account of the Issuing Lender, on demand made by the Issuing Lender, in addition to such amount, interest thereon at the Federal Funds Rate for the first two days following demand and thereafter until paid at the Alternate Base Rate.  Upon receipt by the Administrative Agent from the Lenders of the full amount of such draft, notwithstanding any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of Default) the full amount of such draft shall automatically and without any action by the Company, be deemed to have been a Base Rate Loan as of the date of payment of such draft.  Nothing in this Section 2.13(d) or elsewhere in this Agreement shall diminish the Company’s obligation under this Agreement to provide the funds for the payment of, or on demand to reimburse the Issuing Lender for payment of, any draft presented to, and duly honored by, the Issuing Lender under any Letter of Credit, and the automatic funding of a Loan as provided in this Section 2.13(d) shall not constitute a cure or waiver of the Event of Default for failure to provide timely such funds as agreed in this Section 2.13(d).

45

(e)           In order to induce the issuance of Letters of Credit by the Issuing Lender and the purchase of participations therein by the other Lenders, the Company agrees with the Administrative Agent, the Issuing Lender and the other Lenders that neither the Administrative Agent nor any Lender (including the Issuing Lender) shall be responsible or liable (except as provided in the following sentence) for, and the Company’s unconditional obligation to reimburse the Issuing Lender through the Administrative Agent for amounts paid by the Issuing Lender, as provided in Section 2.13(d) above, on account of drafts so honored under the Letters of Credit shall not be affected by, any circumstance, act or omission whatsoever (whether or not known to the Administrative Agent or any Lender (including the Issuing Lender)) other than a circumstance, act or omission resulting from the gross negligence or willful misconduct of the Administrative Agent or any Lender, including the Issuing Lender.  The Company agrees that any action taken or omitted to be taken by the Administrative Agent or any Lender (including the Issuing Lender) under or in connection with any Letter of Credit or any related draft, document or Property shall be binding on the Company and shall not put the Administrative Agent or any Lender (including the Issuing Lender) under any resulting liability to the Company, unless such action or omission is the result of the gross negligence or willful misconduct of the Administrative Agent or any such Lender (including the Issuing Lender).  The Company hereby waives presentment for payment (except the presentment required by the terms of any Letter of Credit) and notice of dishonor, protest and notice of protest with respect to drafts honored under the Letters of Credit.  The Issuing Lender agrees promptly to notify the Company whenever a draft is presented under any Letter of Credit, but failure to so notify the Company shall not in any way affect the Company’s obligations hereunder.  Subject to Section 3.7, if while any Letter of Credit is outstanding, any law, executive order or regulation is enforced, adopted or interpreted by any public body, governmental agency or court of competent jurisdiction so as to affect any of the Company’s obligations or the compensation to any Lender in respect of the Letters of Credit or the cost to such Lender of establishing or maintaining the Letters of Credit (or any participation therein), such Lender shall promptly notify the Company thereof in writing and within ten Business Days after receipt by the Company of such Lender’s request (through the Administrative Agent) for reimbursement or indemnification or within 30 days after receipt of a notice in respect of Indemnified Taxes, the Company shall reimburse or indemnify such Lender, as the case may be, with respect thereto so that such Lender shall be in the same position as if there had been no such enforcement, adoption or interpretation.  The foregoing agreement of the Company to reimburse or indemnify the Lenders shall apply in (but shall not be limited to) the following situations:  an imposition of or change in reserve, capital maintenance or other similar requirements or in excise or similar Taxes or monetary restraints, except a change in franchise Taxes imposed on such Lender or in Tax on the net income of such Lender.

(f)            In the event that any provision of an LC Application is inconsistent with, or in conflict of, any provision of this Agreement, including provisions for the rate of interest applicable to drawings thereunder or rights of setoff or any representations, warranties, covenants or any events of default set forth therein, the provisions of this Agreement shall govern.

(g)           If the Obligations, or any part thereof, become immediately due and payable pursuant to Article IX of this Agreement, then the entirety of the Letter of Credit Outstandings shall become immediately due and payable without regard for actual drawings or payments on the Letters of Credit, and the Company shall be obligated to pay to the

46

Administrative Agent immediately an amount equal to the entirety of the Letter of Credit Outstandings.  All amounts made due and payable by the Company under this Section 2.13(g) may be applied as the Issuing Lender and the Lenders elect to any of the various Letter of Credit Outstandings; provided, however, that such amounts applied by the Issuing Lender and the Lenders to the Letter of Credit Outstandings shall be (i) first applied to the Matured Letter of Credit Outstandings, and (ii) second held by the Administrative Agent in an interest bearing account for the benefit of the Issuing Lender and the Lenders as LC Collateral, such LC Collateral to be held in an account with the Administrative Agent or an Affiliate thereof, until such remaining portion of the Letter of Credit Outstandings has either (x) become a portion of the Matured Letter of Credit Outstandings, at which time such LC Collateral paid to the Administrative Agent shall be applied to such Matured Letter of Credit Outstandings, or (y) expired undrawn, at which time an amount of such LC Collateral equal to such expired and undrawn Letter of Credit Outstandings, plus accrued interest thereon, shall be applied as otherwise required or permitted under Article IX.  This Section 2.13(g) shall not limit or impair any rights which the Administrative Agent, the Issuing Lender or any of the Lenders may have under any other document or agreement relating to any Letter of Credit or portion of the Letter of Credit Outstandings, including without limitation, any LC Application.

(h)           Any Issuing Lender may resign at any time by giving thirty (30) days prior written notice to the Company, the Administrative Agent, and such resigning Issuing Lender.  The Issuing Lender may be replaced at any time by written agreement among the Company, the Administrative Agent, the replaced Issuing Lender and the successor Issuing Lender.  The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuing Lender.  At the time any such resignation or replacement shall become effective, the Company shall pay all unpaid fees accrued for the account of such resigning or replaced Issuing Lender pursuant to Section 2.8(b).  After the resignation or replacement of an Issuing Lender hereunder, the resigning Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender under this Agreement with respect to the Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase any existing Letter of Credit.

(i)            Cash Collateral.

(i)            The Company shall Cash Collateralize all Letter of Credit Outstandings to the extent required by the terms of this Agreement, including without limitation, Sections 2.6, 2.13, 2.14 and 9.3.  The Company, and to the extent provided by any Defaulting Lender, such Defaulting Lender,  hereby grants to the Administrative Agent, for the benefit of the Lenders, a security interest in all Cash Collateral and all proceeds thereof.  Such cash and deposit account balances shall be maintained in interest bearing deposit accounts with (or on behalf of) the Administrative Agent and/or the Issuing Lender.  Except as otherwise expressly provided herein, upon the drawing of any Letter of Credit for which funds are on deposit as Cash Collateral, such funds shall be applied, to the extent permitted under applicable Law, to reimburse the appropriate Issuing Lender.

(ii)           Cash Collateral (or the appropriate portion thereof) provided to reduce the Issuing Lender’s exposure due to a Defaulting Lender shall no longer be required to be

47

held as Cash Collateral pursuant to this Section 2.13(i) following (x) the elimination or reduction of such exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (y) the determination by the Administrative Agent and the Issuing Lender that there exists excess Cash Collateral; provided that, consistent with clause fifth of Section 2.14(b)(iii), the Company, the Issuing Lender and the Administrative Agent may agree that Cash Collateral shall be held to support future anticipated exposure of the Issuing Lender, the Administrative Agent or the other Lenders (aa) with respect to a Defaulting Lender with respect to future Letters of Credit or (bb) with respect to other obligations owed by a Defaulting Lender hereunder.

Section 2.14           Defaulting Lenders.  (a)  In addition to the other conditions precedent herein set forth, if any Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, the Issuing Lender will not be required to Issue any Letter of Credit unless any exposure that would result therefrom is fully covered or eliminated by any combination of the following:

(i)            in the case of a Defaulting Lender, (x) the Letter of Credit Outstandings of such Defaulting Lender are or (y) the Issuing Lender’s future exposure with respect to such Defaulting Lender with respect to future Letters of Credit is reallocated to the Non-Defaulting Lenders as provided in clause (i) of Section 2.14(b);

(ii)           in the case of a Defaulting Lender or a Potential Defaulting Lender, the Company Cash Collateralizes the obligations of the Company in respect of the proposed Letter of Credit in an amount at least equal to the aggregate amount of the unreallocated obligations (contingent or otherwise) of such Defaulting Lender or Potential Defaulting Lender in respect of such Letter of Credit, or makes other arrangements reasonably satisfactory to the Administrative Agent and the Issuing Lender in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender or Potential Defaulting Lender; and

(iii)          in the case of a Defaulting Lender or a Potential Defaulting Lender, by an instrument or instruments in form and substance reasonably satisfactory to the Administrative Agent and the Issuing Lender, the face amount of such requested Letter of Credit is reduced by an amount equal to the unreallocated, non-Cash Collateralized portion thereof as to which such Defaulting Lender or Potential Defaulting Lender would otherwise be liable, in which case the obligations of the Non-Defaulting Lenders in respect of such Letter of Credit, subject to the first proviso below, shall be on a pro rata basis in accordance with the Commitments of the Non-Defaulting Lenders, and the pro rata payment provisions of Section 2.12 will be deemed adjusted to reflect this provision;

provided that (a) each Non-Defaulting Lender’s total Credit Exposure may not in any event exceed the Commitment of such Non-Defaulting Lender, and (b) neither any such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto nor any such Cash Collateralization or reduction will constitute a waiver or release of any claim the Company, the Administrative Agent, the Issuing Lender, or any other Lender may have against such Defaulting Lender, or cause such Defaulting Lender or Potential Defaulting Lender to be a Non-Defaulting Lender.

48

(b)           Reallocation of Defaulting Lender Commitment.  If a Lender becomes, and during the period it remains, a Defaulting Lender, and so long as no Default or Event of Default has occurred and is continuing, the following provisions shall apply with respect to any Letter of Credit Outstandings of such Defaulting Lender:

(i)            the Letter of Credit Outstandings of such Defaulting Lender will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitments; provided that (a) each Non-Defaulting Lender’s total Credit Exposure may not in any event exceed the Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (b) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Company, the Administrative Agent, the Issuing Lender, or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender;

(ii)           to the extent that any portion (the “unreallocated portion”) of the Defaulting Lender’s Letter of Credit Outstandings cannot be so reallocated, whether by reason of the first proviso in clause (i) above or otherwise, the Company will, not later than two (2) Business Days after demand by the Administrative Agent (at the direction of the Issuing Lender), (a) Cash Collateralize the obligations of the Company to the Issuing Lender in respect of such Letter of Credit Outstandings in an amount at least equal to the aggregate amount of the unreallocated portion of such Letter of Credit Outstandings, or (b) make other arrangements satisfactory to the Administrative Agent, and to the Issuing Lender, in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender; and

(iii)          any amount paid by the Company or otherwise received by the Administrative Agent for the account of a Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity payments or other amounts) will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Administrative Agent in a segregated non-interest bearing account until (subject to Section 2.15) the termination of the Commitments and payment in full of all Obligations of the Company hereunder and will be applied by the Administrative Agent, to the fullest extent permitted by law, to the making of payments from time to time in the following order of priority:  first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent under this Agreement; second, to the payment of any amounts owing by such Defaulting Lender to the Issuing Lender under this Agreement; third, to Cash Collateralize the Issuing Lender’s exposure with respect to such Defaulting Lender in accordance with Section 2.13(i); fourth, as the Company may request (so long as no Default or Event of Default exists), to the funding of any Loan 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 the Company, 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 Loans under this Agreement and (y) Cash Collateralize the Issuing Lender’s future exposure with respect to such Defaulting Lender with respect to

49

future Letters of Credit issued under this Agreement, in accordance with Section 2.13(i); 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 the Company as a result of any judgment of a court of competent jurisdiction obtained by the Company 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 Loans or Matured Letter of Credit Obligations in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 5.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and Letter of Credit Oustandings owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or Letter of Credit Oustandings owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in Letter of Credit Oustandings are held by the Lenders pro rata in accordance with their Commitments without giving effect to Section 2.14(b)(i).  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 2.14(b)(iii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(c)           Fees.  (i)  No Defaulting Lender shall be entitled to receive any fee under Section 2.8(a) for any period during which that Lender is a Defaulting Lender (and the Company shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(ii)           Each Defaulting Lender shall be entitled to receive Letter of Credit fees pursuant to Section 2.8(b)(i) for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Pro Rata Share of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.13 or 2.14(a).

(iii)          With respect to any Letter of Credit fee not required to be paid to any Defaulting Lender pursuant to clause (ii) above, the Company 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 Outstandings that has been reallocated to such Non-Defaulting Lender pursuant to Section 2.14(b)(i), (y) pay to the Issuing Lender the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Lender’s exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(d)           Termination of Defaulting Lender Commitment.  The Company may terminate the unused amount of the Commitment of a Defaulting Lender upon not less than ten (10) Business Days’ prior notice to the Administrative Agent (which will promptly notify the

50

Lenders thereof), and in such event the provisions of Section 2.14(b)(iii) will apply to all amounts thereafter paid by the Company for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts), provided that such termination will not be deemed to be a waiver or release of any claim the Company, the Administrative Agent, the Issuing Lender, or any Lender may have against such Defaulting Lender.

(e)           Qualifying Derivative Contracts.  Transactions under a Derivative Contract entered into with a Lender that is a Defaulting Lender shall constitute Obligations to the extent set forth in the definition of “Obligations”.

Section 2.15           Defaulting Lender Cure.  If the Company, the Administrative Agent and the Issuing Lender agree in writing in their discretion that a Lender is no longer a Defaulting Lender or a Potential Defaulting Lender, as the case may be, 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 amounts then held in the segregated account referred to in Section 2.14(b)), such Lender will, to the extent applicable, purchase at par such portion of outstanding Loans of the other Lenders and/or make such other adjustments as the Administrative Agent may determine to be necessary to cause the Credit Exposure of the Lenders to be on a pro rata basis in accordance with their respective Commitments, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender (and such Credit Exposure) of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Company while such 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 or Potential Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender or Potential Defaulting Lender.

Section 2.16           Increase in Aggregate Commitment.

(a)           Request for Increase.  Provided no Default or Event of Default has occurred and is continuing, upon notice to the Administrative Agent, the Company may from time to time, request an increase in the Aggregate Commitment; provided, however, that (i) any such request for an increase shall be in a minimum amount of $10,000,000, (ii) the Company may make a maximum of four such requests, and (iii) after giving effect to such increase, the Aggregate Commitment shall not be in excess of the Maximum Loan Amount.  At the time of sending such notice, the Company (in consultation with the Administrative Agent) shall specify the time period within which each Lender is requested to respond (which shall in no event be less than ten (10) Business Days from the date of delivery of such notice to the Lenders).

(b)           Lender Elections to Increase.  Each Lender shall notify the Administrative Agent within the time period specified in the notice provided by the Company pursuant to Section 2.16(a) whether or not it agrees to increase its Commitment and, to the extent such Lender agrees to increase its Commitment, such Lender shall indicate whether such increase is by an amount equal to, greater than, or less than its Pro Rata Share of such requested increase.

51

Any Lender not responding within such time period shall be deemed to have declined to increase its Commitment.  No Lender’s Commitment shall be increased without its consent.

(c)           Notification by Administrative Agent; Additional Lenders.  The Administrative Agent shall notify the Company and each Lender of the Lenders’ responses to each request made pursuant to Section 2.16(a).  To achieve the full amount of an increase in the Aggregate Commitment requested by the Borrower, the Company may invite (i) one or more Eligible Assignees and (ii) subject to the approval of the Administrative Agent and the Issuing Lender, one or more other financial institutions, in either case, to become Lenders pursuant to a Joinder Agreement.

(d)           Effectiveness of Aggregate Commitment Increase and Allocations.  If the Aggregate Commitment is increased in accordance with this Section 2.16, the Administrative Agent and the Company shall determine the effective date (the “Aggregate Commitment Increase Effective Date”) and the final allocation of such increase.  The Administrative Agent shall promptly notify the Company and the Lenders of the final allocation of such increase and the Aggregate Commitment Increase Effective Date.  In addition, the Administrative Agent shall determine the Pro Rata Share of each Lender, after giving effect to any such increase.

(e)           Conditions to Effectiveness of Increase.  As a condition precedent to such increase, the Company shall deliver to the Administrative Agent a certificate of each Loan Party dated as of the Aggregate Commitment Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of each such Loan Party (i) certifying and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (ii) in the case of the Company, certifying (1) as to the matters set forth in Section 5.2(b) (provided that the references to “Borrowing Date” shall be deemed to be “Aggregate Commitment Increase Effective Date”), (c), and (d) and (2) that as of the Aggregate Commitment Increase Effective Date and after giving effect to the increase in the Aggregate Commitment being made on such date, such increase in the Aggregate Commitment is permitted under the Second Lien Loan Documents, the Senior Notes Indentures and the Exchange Notes Indentures.  The Company shall prepay any Loans outstanding on the Aggregate Commitment Increase Effective Date (and pay any additional amounts required pursuant to Section 3.4) to the extent necessary to keep the outstanding Loans ratable with any revised Pro Rata Share arising from any nonratable increase in the Commitments under this Section.

(f)            Conflicting Provisions.  This Section 2.16 shall supersede any provisions in Section 2.12 or Section 11.1 to the contrary.

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

Section 3.1             Taxes.  (a)  Any and all payments by the Company to each Lender or the Administrative Agent under this Agreement and any other Loan Document shall be made free and clear of, and without deduction or withholding for any Taxes except as required by applicable Law.  In addition, the Company shall pay all Other Taxes.

52

(b)           Subject to Section 3.1(f), the Company agrees to indemnify and hold harmless each Lender and the Administrative Agent for the full amount of Indemnified Taxes (including any Indemnified Taxes imposed by any jurisdiction on amounts payable under this Section 3.1) paid by the Lender or the Administrative Agent and any liability arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally asserted.  Each Lender shall severally indemnify the Administrative Agent for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Company has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Company to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 11.8(h) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error.  Each Lender hereby authorizes the Administrative Agent to setoff and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this Section 3.1(b).  Payment under this indemnification shall be made within 30 days after the date the affected Lender or the Administrative Agent makes written demand therefor.

(c)           If the Company shall be required by law to deduct or withhold any Taxes or Other Taxes from or in respect of any sum payable hereunder to any Lender or the Administrative Agent, then:  (i) the sum payable shall be increased as necessary so that after making all required deductions and withholdings (including deductions and withholdings applicable to additional sums payable under this Section 3.1), such 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 or withholdings been made; (ii) the Company shall make such deductions and withholdings; (iii) the Company shall pay the full amount deducted or withheld to the relevant Governmental Authority or other authority in accordance with applicable law; and (iv) if such Tax is an Indemnified Tax, the Company shall also pay to each affected Lender or the Administrative Agent for the account of such Lender, at the time interest is paid, all additional amounts which such Lender specifies as necessary to preserve the after-tax yield such Lender would have received if such Indemnified Taxes had not been imposed.

(d)           Within 30 days after the date of any payment by the Company of Indemnified Taxes under Section 3.1(c) above, the Company shall furnish the Administrative Agent the original or a certified copy of a receipt evidencing payment thereof, or other evidence of payment satisfactory to the Administrative Agent.

(e)           If the Company is required to pay additional amounts to any Lender or the Administrative Agent pursuant to Section 3.1(c), then upon written request of the Company such Lender shall use reasonable efforts (consistent with legal and regulatory restrictions) to change the jurisdiction of its Lending Office so as to eliminate any such additional payment by the Company which may thereafter accrue, if such change in the judgment of such Lender is not otherwise disadvantageous to such Lender.

53

(f)            No Lender that is required to comply with Section 10.10 shall be entitled to any indemnification under this Section 3.1 if the obligation with respect to which indemnification is sought would not have arisen but for a failure of the affected Lender to comply with such Section 10.10.

Section 3.2             Illegality.  (a)  If any Lender determines that any Change in Law, has made it unlawful, or that any central bank or other Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make LIBO Rate Loans, then, on notice thereof by the Lender to the Company through the Administrative Agent, any obligation of that Lender to make LIBO Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Company that the circumstances giving rise to such determination no longer exist.

(b)           If a Lender determines that it is unlawful to maintain any LIBO Rate Loan, the Company shall, upon its receipt of notice of such fact and demand from such Lender (with a copy to the Administrative Agent), prepay in full such LIBO Rate Loans of that Lender then outstanding, together with interest accrued thereon and amounts required under Section 3.4, either on the last day of the Interest Period thereof, if the Lender may lawfully continue to maintain such LIBO Rate Loans to such day, or immediately, if the Lender may not lawfully continue to maintain such LIBO Rate Loan.  If the Company is required to so prepay any LIBO Rate Loan, then concurrently with such prepayment, the Company shall borrow from the affected Lender, in the amount of such repayment, a Base Rate Loan.

(c)           If the obligation of any Lender to make or maintain LIBO Rate Loans has been so terminated or suspended, all Loans which would otherwise be made by the Lender as LIBO Rate Loans shall be instead Base Rate Loans.

(d)           Before giving any notice to the Administrative Agent under this Section 3.2, the affected Lender shall designate a different Lending Office with respect to its LIBO Rate Loans if such designation will avoid the need for giving such notice or making such demand and will not, in the judgment of such Lender, be illegal or otherwise disadvantageous to such Lender.

Section 3.3             Increased Costs and Reduction of Return.  (a)  If any Lender determines that, due to either (i) any Change in Law (other than any change by way of imposition of or increase in reserve requirements included in the calculation of the LIBO Rate) or (ii) the compliance by that Lender with any guideline or request from any central bank or other Governmental Authority (including ▇▇▇▇-▇▇▇▇▇/Basel) (whether or not having the force of law), there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining any LIBO Rate Loans, then the Company shall be liable for, and shall from time to time, upon demand (with a copy of such demand to be sent to the Administrative Agent), pay to the Administrative Agent for the account of such Lender, additional amounts as are sufficient to compensate such Lender for such increased costs.

(b)           If any Lender shall have determined that (i) the introduction of any Capital Adequacy Regulation (including ▇▇▇▇-▇▇▇▇▇/Basel), (ii) any change in any Capital Adequacy Regulation (including ▇▇▇▇-▇▇▇▇▇/Basel), (iii) any change in the interpretation or administration

of any Capital Adequacy Regulation by any central bank or other Governmental Authority charged with the interpretation or administration thereof (including ▇▇▇▇-▇▇▇▇▇/Basel), or (iv) compliance by such Lender (or its Lending Office) or any Affiliate controlling such Lender with any Capital Adequacy Regulation (including ▇▇▇▇-▇▇▇▇▇/Basel), affects or would affect the amount of capital required or expected to be maintained by such Lender or any Affiliate controlling such Lender and (taking into consideration such Lender’s or such Affiliate’s policies with respect to capital adequacy and such Lender’s desired return on capital) determines that the amount of such capital is increased as a consequence of its Commitment, Loans, other Credit Extensions, or Obligations under this Agreement, then, upon demand of such Lender to the Company through the Administrative Agent, the Company shall pay to such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender for such increase.

Section 3.4             Funding Losses.  The Company shall reimburse each Lender and hold each Lender harmless from any loss or expense which the Lender may sustain or incur as a consequence of (a) the failure of the Company to make on a timely basis any payment of principal of any LIBO Rate Loan; (b) the failure of the Company to borrow or continue a LIBO Rate Loan or to convert a Base Rate Loan to a LIBO Rate Loan after the Company has given (or is deemed to have given) a Notice of Borrowing or a Notice of Conversion/Continuation (including by reason of the failure to satisfy any condition precedent thereto); (c) the failure of the Company to make any prepayment in accordance with any notice delivered under Section 2.5; (d) the prepayment (including pursuant to Section 2.6) or other payment (including after acceleration thereof) of a LIBO Rate Loan on a day that is not the last day of the relevant Interest Period; or (e) the automatic conversion under Section 2.3 of any LIBO Rate Loan to a Base Rate Loan on a day that is not the last day of the relevant Interest Period; including any such loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain its LIBO Rate Loans or from fees payable to terminate the deposits from which such funds were obtained (but excluding any loss of margin).  For purposes of calculating amounts payable by the Company to the Lenders under this Section 3.4 and under Section 3.3(a), each LIBO Rate Loan made by a Lender (and each related reserve, special deposit or similar requirement) shall be conclusively deemed to have been funded at the LIBOR used in determining the LIBO Rate for such LIBO Rate Loan by a matching deposit or other borrowing in the interbank eurodollar market for a comparable amount and for a comparable period, whether or not such LIBO Rate Loan is in fact so funded.

Section 3.5             Inability to Determine Rates.  If the Administrative Agent determines that for any reason adequate and reasonable means do not exist for determining the LIBO Rate for any requested Interest Period with respect to a proposed LIBO Rate Loan, or that the LIBO Rate applicable pursuant to Section 2.7(b) for any requested Interest Period with respect to a proposed LIBO Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such Loan, the Administrative Agent will promptly so notify the Company and each Lender.  Thereafter, the obligation of the Lenders to make or maintain LIBO Rate Loans hereunder shall be suspended until the Administrative Agent upon the instruction of the Lenders revokes such notice in writing.  Upon receipt of such notice, the Company may revoke any Notice of Borrowing or Notice of Conversion/Continuation then submitted by it.  If the Company does not revoke such notice, the Lenders shall make, convert or continue the Loans, as proposed by the

55

Company, in the amount specified in the applicable notice submitted by the Company, but such Loans shall be made, converted or continued as Base Rate Loans instead of LIBO Rate Loans.

Section 3.6             Certificates of Lenders.  Any Lender claiming reimbursement or compensation under this Article III shall deliver to the Company (with a copy to the Administrative Agent) a certificate setting forth in reasonable detail the amount payable to such Lender hereunder and such certificate shall be conclusive and binding on the Company in the absence of manifest error; provided, however, that such Lender shall only be entitled to collect amounts incurred within 180 days of such notice.

Section 3.7             Substitution of Lenders.  Upon (i) the receipt by the Company from any Lender of a claim for compensation under this Article III, (ii) the refusal of a Lender to accept the Annual Proposed Borrowing Base pursuant to Section 2.6(b) or Semi-Annual Proposed Borrowing Base pursuant to Section 2.6(c) (as applicable) or (iii) a Lender becoming a Defaulting Lender, and, as a result, the Company elects by written notice to the Administrative Agent to replace such Lender pursuant to this Section 3.7 (such Lender, an “Affected Lender”), the Company may:  (a) obtain a replacement bank or financial institution satisfactory to the Administrative Agent to acquire and assume all or a ratable part of all of such Affected Lender’s Loans and Commitment (a “Replacement Lender”); or (b) request one more of the other Lenders to acquire and assume all or part of such Affected Lender’s Loans and Commitment but none of the Lenders shall have any obligation to do so.  Any such designation of a Replacement Lender under clause (a) shall be subject to the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld.  The appointment of a Replacement Lender shall be effectuated by a Lender Assignment Agreement entered into by such Affected Lender and such one or more Replacement Lenders (together with any consents for such assignment required hereunder).

Section 3.8             Survival.  The agreements and obligations of the Company in this Article III shall survive the payment of all other Obligations.

56

Section 4.2             Agreement to Deliver Security Documents.  The Company shall, and shall cause its Restricted Subsidiaries (other than Ellwood) where applicable, to deliver whenever reasonably requested by the Administrative Agent, (a) favorable title opinions from legal counsel reasonably acceptable to the Administrative Agent, or such other evidence of title reasonably satisfactory to the Administrative Agent with respect to the Mortgaged Properties, based upon abstract or record examinations acceptable to the Administrative Agent with respect to at least 80% of the Net Present Value of the Proved Reserves and 90% of the Net Present Value of the Proved Developed Producing Reserves, and providing that such Properties are free and clear of all Liens except Permitted Liens and covering such other matters as the Administrative Agent may reasonably request and (b) evidence that at least eighty-five (85%) of the Net Present Value of the Proved Reserves and at least ninety-five percent (95%) of the Net Present Value of the Proved Developed Producing Reserves, in each case as set forth in the most recent Reserve Report, are subject to Security Documents securing the Obligations that constitute and create legal, valid and duly perfected deed of trust or mortgage Liens in such Mortgaged Properties and interests, and assignments of and security interests in the Oil and Gas attributable to such Mortgaged Properties comprised of Oil and Gas Properties and interests and the proceeds thereof, in each case subject only to Permitted Liens.

Section 4.3             (Reserved).

Section 4.4             Setoff.  Each Lender, Issuing Lender and their Affiliates shall, upon the occurrence and during the continuance of any Event of Default described in clauses (g) and (h) of Section 9.1 or, with the consent of the Required Lenders, upon the occurrence and during the continuance of any other Event of Default, have the right to appropriate and apply to the payment of the Obligations owing to it (whether or not then due), any and all balances, credits, deposits, accounts or moneys of the Company then or thereafter maintained with such Secured Party; provided that, any such appropriation and application shall be subject to the provisions of Section 2.12.  Each Lender and Issuing Lender agrees promptly to notify the Company and the Administrative Agent after any such appropriation and application made by such Person or its Affiliates; provided that, the failure to give such notice shall not affect the validity of such setoff and application; provided further that in the event that any Defaulting Lender exercises any such right of setoff, (x) all amounts so set off will be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.10 and, pending such payment, will be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuing Lender and the Lenders and (y) the Defaulting Lender will provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff.  The rights of each Secured Party under this Section are in addition to other rights and remedies (including other rights of setoff under law or otherwise) which such Secured Party may have.

Section 4.5             Guaranty.  (a)  Each Guarantor has executed and delivered to the Administrative Agent, and each Restricted Subsidiary (other than Ellwood) of the Company now existing or created, acquired or coming into existence after the date hereof shall, promptly upon request by the Administrative Agent, execute and deliver to the Administrative Agent, a Guaranty setting forth therein an absolute and unconditional guaranty of the timely repayment of, and the due and punctual performance of the Obligations of the Company, which Guaranty shall

57

be reasonably satisfactory to the Administrative Agent in form and substance.  The Company will cause each of its Restricted Subsidiaries (other than Ellwood) to deliver to the Administrative Agent, simultaneously with its delivery of such a Guaranty, written evidence reasonably satisfactory to the Administrative Agent and its counsel that such Restricted Subsidiary has taken all corporate, limited liability company or partnership action necessary to duly approve and authorize its execution, delivery and performance of such Guaranty and any Security Documents and other documents which it is required to execute.

(b)           Guaranty Representations.  Each Loan Party represents and warrants to the Administrative Agent and the Lenders at the Effective Time:

(i)            Benefit to Guarantors.  The Loan Parties are mutually dependent on each other in the conduct of their respective businesses, with the credit needed from time to time by each often being provided by another or by means of financing obtained by one such Affiliate with the support of the other for their mutual benefit and the ability of each to obtain such financing is dependent on the successful operations of the other.  The board of directors, manager or general partner or similar governing body, of each Guarantor has determined that such Guarantor’s execution, delivery and performance of this Agreement may reasonably be expected to directly or indirectly benefit such Guarantor and is in the best interests of such Guarantor.

(ii)           Reasonable Consideration for Guaranties.  The direct or indirect value of the consideration received and to be received by such Guarantor in connection herewith is reasonably worth at least as much as the liability and obligations of each Guarantor hereunder and its Guaranty, and the incurrence of such liability and obligations in return for such consideration may reasonably be expected to benefit such Guarantor, directly or indirectly.

(iii)          Benefit to Lenders.  The Loan Parties acknowledge that, but for the making of the Guaranties, the Lenders would not be making the Loans hereunder.

Section 4.6             Production Proceeds.  Notwithstanding that, by the terms of the various Security Documents, the Company is and will be assigning to the Administrative Agent all of the Net Proceeds of Production accruing to the Mortgaged Properties covered thereby, so long as no Event of Default has occurred and is continuing, the Administrative Agent, on behalf of the Secured Parties, grants each of the Company and its Subsidiaries a revocable license to continue to receive from the purchasers of production all such Net Proceeds of Production, subject, however, to the Liens created under the Security Documents, which Liens are hereby affirmed and ratified.  During the continuance of an Event of Default described under Sections 9.1(g) or 9.1(h), this license shall be automatically revoked, and during the continuance of any other Event of Default, this license shall be revocable in the sole discretion of the Administrative Agent, by notice to the Company, and the Administrative Agent may exercise all rights and remedies granted under the Security Documents, including the right to obtain possession of all Net Proceeds of Production then held by the Loan Parties or to receive directly from the purchasers of production all other Net Proceeds of Production.  In no case shall any failure, whether purposeful or inadvertent, by the Administrative Agent to collect directly any such Net Proceeds of Production constitute in any way a waiver, remission or release of any of

58

its rights under the Security Documents, nor shall any release of any Net Proceeds of Production by the Administrative Agent to the Loan Parties constitute a waiver, remission, or release of any other Net Proceeds of Production or of any rights of the Administrative Agent to collect other Net Proceeds of Production thereafter.

Section 6.2             Corporate Authorization; No Contravention.  The execution, delivery and performance by the Loan Parties of this Agreement and each other Loan Document to which such Person is a party have been duly authorized by all necessary organizational action, and do not and will not:  (a) contravene the terms of any of that Person’s Organization Documents; (b) contravene any Second Lien Debt Instrument or any Senior Notes Indenture; (c) conflict with or result in any breach or contravention of, or the creation of any Lien under, any document evidencing any material Contractual Obligation to which such Person is a party that would be prior to the Liens granted to the Administrative Agent for the benefit of the

63

Lenders or otherwise that would constitute a Material Adverse Effect, or any order, injunction, writ or decree of any Governmental Authority to which such Person or its material Property is subject; or (d) violate any Requirement of Law, except where any such contravention, conflict or violation individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect.

Section 6.3             Governmental Authorization.  No approval, permit, consent, exemption, authorization, or other action by, or notice to, or filing with, any Governmental Authority is necessary in connection with the execution, delivery or performance by, or enforcement against, the Company or any other Loan Party of this Agreement or any other Loan Document to which it is a party, except for filings necessary to obtain and maintain perfection of Liens; routine filings related to the Company and the operation of its business; and such filings as may be necessary in connection with the Lenders’ exercise of remedies hereunder.

Section 6.4             Binding Effect.  This Agreement and each other Loan Document to which the Company or any Restricted Subsidiary is a party constitute the legal, valid and binding obligations of the Company and such Restricted Subsidiaries to the extent it is a party thereto, enforceable against such Person in accordance with their respective terms, except as enforceability may be limited by applicable bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles relating to enforceability.

Section 6.9             Title to Properties.  The Company and each Restricted Subsidiary have good and marketable title to the Mortgaged Properties subject only to Permitted Liens, and, except for such defects in title as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, have good and marketable title to, or valid leasehold

65
