In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the L/C Issuer: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the

full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as the L/C Issuer may require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the L/C Issuer (A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as the L/C Issuer may require. Additionally, the Borrower shall furnish to the L/C Issuer and the Administrative Agent such other documents and information pertaining to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as the L/C Issuer or the Administrative Agent may require.

(ii) Promptly after receipt of any Letter of Credit Application, the L/C Issuer will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Unless the L/C Issuer has received written notice from any Lender, the Administrative Agent or any Loan Party, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in Article IV shall not then be satisfied, then, subject to the terms and conditions hereof, the L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with the L/C Issuer’s usual and customary business practices. Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the L/C Issuer a risk participation in such Letter of Credit in an amount equal to the product of such Lender’s Applicable Percentage times the amount of such Letter of Credit.

(iii) If the Borrower so requests in any applicable Letter of Credit Application, the L/C Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the L/C Issuer to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the L/C Issuer, the Borrower shall not be required to make a specific request to the L/C Issuer for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to permit the extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date; provided, however, that the L/C Issuer shall not permit any such extension if (A) the L/C Issuer has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (ii) or (iii) of Section 2.03(a) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the Non-Extension Notice Date (1) from the Administrative Agent

that the Required Lenders have elected not to permit such extension or (2) from the Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied, and in each such case directing the L/C Issuer not to permit such extension.

(iv) If the Borrower so requests in any applicable Letter of Credit Application, the L/C Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that permits the automatic reinstatement of all or a portion of the stated amount thereof after any drawing thereunder (each, an “Auto-Reinstatement Letter of Credit”). Unless otherwise directed by the L/C Issuer, the Borrower shall not be required to make a specific request to the L/C Issuer to permit such reinstatement. Once an Auto-Reinstatement Letter of Credit has been issued, except as provided in the following sentence, the Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to reinstate all or a portion of the stated amount thereof in accordance with the provisions of such Letter of Credit. Notwithstanding the foregoing, if such Auto-Reinstatement Letter of Credit permits the L/C Issuer to decline to reinstate all or any portion of the stated amount thereof after a drawing thereunder by giving notice of such non-reinstatement within a specified number of days after such drawing (the “Non-Reinstatement Deadline”), the L/C Issuer shall not permit such reinstatement if it has received a notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Reinstatement Deadline (A) from the Administrative Agent that the Required Lenders have elected not to permit such reinstatement or (B) from the Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied (treating such reinstatement as an L/C Credit Extension for purposes of this clause) and, in each case, directing the L/C Issuer not to permit such reinstatement.

(v) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the L/C Issuer will also deliver to the Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

(i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall notify the Borrower and the Administrative Agent thereof. Not later than 11:00 a.m. on the date of any payment by the L/C Issuer under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse the L/C Issuer by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Applicable Percentage thereof. In such event, the Borrower shall be deemed to have requested a Committed Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Commitments

and the conditions set forth in Section 4.02 (other than the delivery of a Committed Loan Notice). Any notice given by the L/C Issuer or the Administrative Agent pursuant to this Section 2.03(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Lender shall upon any notice pursuant to Section 2.03(c)(i) make funds available to the Administrative Agent for the account of the L/C Issuer at the Administrative Agent’s Office in an amount equal to its Applicable Percentage of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.03(c)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Committed Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the L/C Issuer.

(iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Committed Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment to the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03.

(iv) Until each Lender funds its Committed Loan or L/C Advance pursuant to this Section 2.03(c) to reimburse the L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Applicable Percentage of such amount shall be solely for the account of the L/C Issuer.

(v) Each Lender’s obligation to make Committed Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the L/C Issuer, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Committed Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the Borrower of a Committed Loan Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse the L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit, together with interest as provided herein.

(vi) If any Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the

foregoing provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the L/C Issuer in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the L/C Issuer in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Committed Loan included in the relevant Committed Borrowing or L/C Advance in respect of the relevant L/C Borrowing, as the case may be. A certificate of the L/C Issuer submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

(d) Repayment of Participations.

(i) At any time after the L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.03(c), if the Administrative Agent receives for the account of the L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Applicable Percentage thereof in the same funds as those received by the Administrative Agent.

(ii) If any payment received by the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(i) is required to be returned under any of the circumstances described in Section 10.05 (including pursuant to any settlement entered into by the L/C Issuer in its discretion), each Lender shall pay to the Administrative Agent for the account of the L/C Issuer its Applicable Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Obligations Absolute. The obligation of the Borrower to reimburse the L/C Issuer for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other Loan Document;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the L/C Issuer or any other Person, whether in connection

with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or 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; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) any payment by the L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

(v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or any Subsidiary.

The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the L/C Issuer. The Borrower shall be conclusively deemed to have waived any such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid.

(f) Role of L/C Issuer. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the L/C Issuer, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the L/C Issuer, the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of the L/C Issuer shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.03(e); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to

consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful failure to pay under any Letter of Credit after the 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, the L/C Issuer 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, and the L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if, as of the Letter of Credit Expiration Date, any L/C Obligation for any reason remains outstanding, the Borrower shall, in each case, immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations. Sections 2.05 and 8.02(c) set forth certain additional requirements to deliver Cash Collateral hereunder. For purposes of this Section 2.03, Section 2.06 and Section 8.02(c), “Cash Collateralize” means to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, as collateral for the L/C Obligations, cash or deposit account balances pursuant to documentation in form and substance satisfactory to the Administrative Agent and the L/C Issuer (which documents are hereby consented to by the Lenders). Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash Collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America.

(h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the L/C Issuer and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance shall apply to each commercial Letter of Credit.

(i) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Applicable Percentage a Letter of Credit fee (the “Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Rate times the daily amount available to be drawn under such Letter of Credit. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.07. Letter of Credit Fees shall be (i) due and payable on the first Business Day after the end of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand and (ii) computed on a quarterly basis in arrears. If there is any change in the Applicable Rate during any quarter, the daily amount available to be drawn under each Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect. Notwithstanding anything to the contrary contained herein, upon the request of the

Required Lenders, while any Event of Default exists, all Letter of Credit Fees shall accrue at the Default Rate.

(j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each Letter of Credit, at the rate of 0.125% per annum, (i) with respect to each commercial Letter of Credit, computed on the amount of such Letter of Credit and payable upon the issuance thereof, (ii) with respect to any amendment of a commercial Letter of Credit increasing the amount of such Letter of Credit, computed on the amount of such increase, and payable upon the effectiveness of such amendment, and (iii) with respect to each standby Letter of Credit, computed on the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears, and due and payable on the first Business Day after the end of each March, June, September and December in respect of the most recently-ended quarterly period (or portion thereof, in the case of the first payment), commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. For purposes of computing the daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section 1.07. In addition, the Borrower shall pay directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the L/C Issuer relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

(k) Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control.

2.04 Swing Line Loans.

(a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.04, to make loans (each such loan, a “Swing Line Loan”) to the Borrower from time to time on any Business Day during the Availability Period in an aggregate amount not to exceed at any time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact that such Swing Line Loans, when aggregated with the Applicable Percentage of the Outstanding Amount of Committed Loans and L/C Obligations of the Lender acting as Swing Line Lender, may exceed the amount of such Lender’s Commitment; provided, however, that after giving effect to any Swing Line Loan, (i) the Total Outstandings shall not exceed the lesser of the Aggregate Commitments and the Borrowing Base, and (ii) the aggregate Outstanding Amount of the Committed Loans of any Lender, plus such Lender’s Applicable Percentage of the Outstanding Amount of all L/C Obligations, plus such Lender’s Applicable Percentage of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Commitment, and provided, further, that the Borrower shall not use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may borrow under this Section 2.04, prepay under Section 2.06, and reborrow under this Section 2.04. Each Swing Line Loan shall be a Base Rate Loan. Immediately upon the making of a Swing Line Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender a risk

participation in such Swing Line Loan in an amount equal to the product of such Lender’s Applicable Percentage times the amount of such Swing Line Loan.

(b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the Borrower’s irrevocable notice to the Swing Line Lender and the Administrative Agent, which may be given by telephone. Each such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $100,000, and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice must be confirmed promptly by delivery to the Swing Line Lender and the Administrative Agent of a written Swing Line Loan Notice, appropriately completed and signed by a Responsible Officer of the Borrower. Promptly after receipt by the Swing Line Lender of any telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Swing Line Loan Notice and, if not, the Swing Line Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the request of any Lender) prior to 2:00 p.m. on the date of the proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the proviso to the first sentence of Section 2.04(a), or (B) that one or more of the applicable conditions specified in Article IV is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 3:00 p.m. on the borrowing date specified in such Swing Line Loan Notice, make the amount of its Swing Line Loan available to the Borrower at its office by crediting the account of the Borrower on the books of the Swing Line Lender in immediately available funds.

(i) The Swing Line Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make a Base Rate Committed Loan in an amount equal to such Lender’s Applicable Percentage of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Committed Loan Notice for purposes hereof) and in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.02. The Swing Line Lender shall furnish the Borrower with a copy of the applicable Committed Loan Notice promptly after delivering such notice to the Administrative Agent. Each Lender shall make an amount equal to its Applicable Percentage of the amount specified in such Committed Loan Notice available to the Administrative Agent in immediately available funds for the account of the Swing Line Lender at the Administrative Agent’s Office not later than 1:00 p.m. on the day specified in such Committed Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Lender that so makes funds available shall be deemed to have made a Base Rate Committed Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swing Line Lender.

(ii) If for any reason any Swing Line Loan cannot be refinanced by such a Committed Borrowing in accordance with Section 2.04(c)(i), the request for Base Rate Committed Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in the relevant Swing Line Loan and each Lender’s payment to the Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.04(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to the Administrative Agent for the account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.04(c) by the time specified in Section 2.04(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swing Line Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Committed Loan included in the relevant Committed Borrowing or funded participation in the relevant Swing Line Loan, as the case may be. A certificate of the Swing Line Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Committed Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Committed Loans pursuant to this Section 2.04(c) is subject to the conditions set forth in Section 4.02. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swing Line Loans, together with interest as provided herein.

(d) Repayment of Participations.

(i) At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Applicable Percentage thereof in the same funds as those received by the Swing Line Lender.

(ii) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to be returned by the Swing Line Lender under any of the circumstances described in Section 10.05 (including pursuant to any

settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender its Applicable Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the Borrower for interest on the Swing Line Loans. Until each Lender funds its Base Rate Committed Loan or risk participation pursuant to this Section 2.04 to refinance such Lender’s Applicable Percentage of any Swing Line Loan, interest in respect of such Applicable Percentage shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. The Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender.

2.05 Borrowing Base

(a) Initial Borrowing Base. During the period from the Closing Date until the next Determination Date the Borrowing Base shall be $300,000,000.

(b) Subsequent Determinations of the Borrowing Base. Upon each designation of a new Borrowing Base on a Scheduled Determination or a Special Determination, the Administrative Agent shall notify the Borrower of the new Borrowing Base which designation shall take effect immediately on the date such notice is sent (each such date, a “Determination Date”) and shall remain in effect until, but not including, the next Determination Date. The Borrowing Base shall be determined in accordance with the following methodology:

(i) By April 1 and October 1 of each year beginning April 1, 2007, the Borrower shall furnish to the Administrative Agent (with sufficient copies for each Lender of any information provided on paper, computer disks, or other tangible media) the Engineering Report then required under Section 6.01(d) or (e) together with all information, reports and data that the Administrative Agent requests concerning the businesses and properties of the Borrower and its Subsidiaries (including their Oil and Gas Properties and the reserves and production relating thereto). As promptly as reasonably practicable after receiving such Engineering Report, information, reports and data, the Administrative Agent shall propose a Borrowing Base following the procedures set forth in Section 2.05(b)(iii) below. Each such determination of the Borrowing Base is herein called a “Scheduled Determination”. If the Borrower does not furnish all such information, reports and data by the date specified in the first sentence of this Section, the Administrative Agent may nonetheless designate the Borrowing Base at any amount that Required Lenders determine (or, in the case of an increase, that all the Lenders determine) and the Borrowing Base may similarly be designated from time to time thereafter until each Lender receives all such information, reports and data, whereupon the Lenders shall designate a new Borrowing Base as described above.

(ii) In addition to Scheduled Determinations, the Borrower may request the Lenders to make additional determinations of the Borrowing Base (x) twice during the twelve

months following the Closing Date and (y) thereafter once during each twelve month interval between Scheduled Determinations, and the Administrative Agent also may (and at the request of Required Lenders must) request the Lenders to make an additional determination of the Borrowing Base (x) once during the twelve months following the Closing Date and (y) thereafter once during each twelve month interval between Scheduled Determinations. The Administrative Agent shall give notice to the Borrower of any such request made by the Administrative Agent to the Lenders. The Borrower shall submit any such request made by Borrower to Administrative Agent and each Lender and, at the time of such request, the Borrower shall (A) deliver to the Administrative Agent and each Lender an updated Engineering Report prepared either by the Borrower or by independent petroleum engineers, and (B) notify the Administrative Agent and each Lender of the Borrowing Base requested by the Borrower. Any determination of the Borrowing Base made pursuant to a request under this clause (ii) is herein called a “Special Determination”. Any Special Determination shall be made by Lenders in accordance with the procedures set forth in Section 2.05(b)(iii), provided, however, that the Borrower shall not be required to deliver an updated Engineering Report to the Administrative Agent and Lenders in connection with any Special Determination requested by the Administrative Agent.

(iii) The Administrative Agent shall (within 30 days after receiving the information, if any, required for a Scheduled Determination or a Special Determination) propose to the Lenders a specific Borrowing Base amount for the Lenders to approve or disapprove. Within 15 days thereafter each Lender shall respond to the Administrative Agent in writing, either approving such proposed amount or setting out a reasonable alternative amount (based on the criteria described in clause (v) below), and any Lender’s failure to respond to such proposal within such time will be deemed a disapproval of the proposed amount. After receiving such responses or deemed responses from all Lenders, the Administrative Agent will designate the new Borrowing Base at the highest amount approved (i) by all Lenders, in the case of an increase to the then current Borrowing Base, or (ii) at the highest amount approved by Required Lenders, in the case of a reduction to or continuation of the then current Borrowing Base.

(iv) In addition to the foregoing, the Administrative Agent and Lenders shall also have the right to adjust the Borrowing Base (which shall not count as a Special Determination but which shall otherwise be done in accordance with the procedures set forth in Section 2.05(b)(iii)) if the Borrower or any Subsidiaries sell or otherwise transfer (excluding transfers to the Borrower or a Subsidiary of the Borrower that is a Guarantor) Oil and Gas Properties that, on a cumulative basis since the then most recent Determination Date, represent more than ten percent of the net present value of all of their proved reserves, as determined in the most recently delivered Engineering Report.

(v) Each redetermination of the Borrowing Base pursuant to this Section 2.05 shall be made in good faith by all of the Lenders and the Administrative Agent, in the exercise of their reasonable discretion and in accordance with their respective customary and prudent standards for oil and gas lending and credit transactions as they exist at such time. Without limiting such discretion, Borrower acknowledges and agrees that the Administrative Agent and the Lenders (i) may make such assumptions regarding appropriate existing and projected pricing for Hydrocarbons as they deem appropriate in their discretion, (ii) may make such assumptions regarding projected rates and quantities of future production of Hydrocarbons from the Oil and Gas Properties owned by Borrower and its Subsidiaries as they deem appropriate in their discretion, (iii) may consider the projected cash requirements of Borrower and its Subsidiaries,

(iv) are not required to consider any asset other than Proved Reserves owned by Borrower and its Subsidiaries, and (v) may make such other assumptions, considerations and exclusions as they deems appropriate in the exercise of their discretion. It is further acknowledged and agreed that the Administrative Agent and the Lenders may consider such other credit factors as they deem appropriate in the exercise of their discretion.

(c) Borrowing Base Deficiency. If a Borrowing Base Deficiency exists at any time, the Borrower shall, within ten (10) days after being notified of such Borrowing Base Deficiency, provide written notice (the “Election Notice”) to Lender stating the action which Borrower proposes to take to remedy such Borrowing Base Deficiency, and the Borrower shall thereafter, at its option, do one or a combination of the following in an aggregate amount sufficient to eliminate such Borrowing Base Deficiency:

(i) within ten (10) days following the delivery of such Election Notice, make a prepayment of the Loans,

(ii) pay monthly installments of the Outstanding Amount of the Loans over a term and in an amount satisfactory to the Administrative Agent, but in any event not to exceed six months, by immediately dedicating a sufficient amount of monthly cash flow from the Oil and Gas Properties of the Borrower and its Subsidiaries,

(iii) within thirty (30) days following the delivery of the Election Notice, submit additional Oil and Gas Properties to the Administrative Agent for evaluation as Borrowing Base Properties which the Administrative Agent, in its sole discretion, determines have a value sufficient to increase the Borrowing Base by at least the amount of the Borrowing Base Deficiency (after giving effect to other actions taken pursuant to this Section 2.05(c) that have the effect of reducing such Borrowing Base Deficiency), and/or

(iv) within thirty (30) days following the delivery of such Election Notice, apply the Net Cash Proceeds from a Disposition permitted by Section 7.05(g) to reduce the Borrowing Base Deficiency after giving effect to any reduction of the Borrowing Base as determined by the Required Lenders as a result of such sale.

2.06 Prepayments.

(a) Optional.

(i) The Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Committed Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than 11:00 a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans and (B) on the date of prepayment of Base Rate Committed Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Committed Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Committed Loans to be prepaid and, if Eurodollar Rate Loans are to be prepaid, the Interest Period(s) of such Loans. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Applicable Percentage of such prepayment. If such notice is given

by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05. Each such prepayment shall be applied to the Committed Loans of the Lenders in accordance with their respective Applicable Percentages.

(ii) The Borrower may, upon notice to the Swing Line Lender (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and (ii) any such prepayment shall be in a minimum principal amount of $100,000. Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

(b) Mandatory.

(i) If for any reason the Total Outstandings at any time exceed the Aggregate Commitments then in effect, the Borrower shall immediately prepay Loans and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided, however, that the Borrower shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.06(b) unless after the prepayment in full of the Loans the Total Outstandings exceed the Aggregate Commitments then in effect.

(ii) If the Borrower or any of its Subsidiaries Disposes of any property under Section 7.05(g) which results in the realization by such Person of Net Cash Proceeds, the Borrower shall use the Net Cash Proceeds to eliminate any Borrowing Base Deficiency resulting from such sale; provided that, the proceeds of any Disposition permitted by Section 7.05(g) shall not constitute Net Cash Proceeds to the extent that (A) such proceeds are reinvested in replacement properties or assets, or other productive properties or assets, acquired by the Borrower or a Subsidiary of a kind then used or usable in the business of the applicable Person (with equal or greater aggregate Attributed Value) within 180 days from the date of receipt thereof or (B) if the applicable Borrower or Subsidiary intends to acquire replacement properties or assets, or other productive properties or assets, with such proceeds as part of a like-kind exchange under Section 1031 of the Code, the potential replacement properties or assets are identified by such Borrower or Subsidiary within 180 days from the date the ownership to the sold assets is transferred to the buyer of such property and the proceeds from such property are reinvested to acquire such replacement properties or assets (with equal or greater aggregate Attributed Value) within 180 days from the date the ownership to the sold assets is transferred to the buyer of such property; provided further that, the proceeds of any Casualty Event shall not constitute Net Cash Proceeds to the extent that such proceeds are reinvested in replacement properties or assets, or other productive properties or assets, acquired by the Borrower or a Guarantor of a kind then used or usable in the business of the applicable Person (with equal or greater aggregate Attributed Value) within 180 days from the date of receipt thereof.

(iii) Upon the incurrence or issuance by the Borrower or any of its Subsidiaries of any Indebtedness (other than Indebtedness expressly permitted to be incurred or issued pursuant to Section 7.03, the Borrower shall prepay an aggregate principal amount of Loans equal to 100% of all Net Cash Proceeds received therefrom immediately upon receipt thereof by the Borrower or such Subsidiary (such prepayments to be applied as set forth in clause (iv) below).

(iv) Prepayments of the Total Outstandings made pursuant to this Section 2.06(b), first, shall be applied ratably to the L/C Borrowings, second, shall be applied ratably to the outstanding Loans, and, third, shall be used to Cash Collateralize the remaining L/C Obligations. Upon the drawing of any Letter of Credit that has been Cash Collateralized, the funds held as Cash Collateral shall be applied (without any further action by or notice to or from the Borrower or any other Loan Party) to reimburse the L/C Issuer or the Lenders, as applicable.

2.07 Termination or Reduction of Commitments. The Borrower may, upon notice to the Administrative Agent, terminate the Aggregate Commitments, or from time to time permanently reduce the Aggregate Commitments; provided that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m. five Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $10,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) the Borrower shall not terminate or reduce the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Outstandings would exceed the Aggregate Commitments, and (iv) if, after giving effect to any reduction of the Aggregate Commitments, the Letter of Credit Sublimit or the Swing Line Sublimit exceeds the amount of the Aggregate Commitments, such Sublimit shall be automatically reduced by the amount of such excess. The Administrative Agent will promptly notify the Lenders of any such notice of termination or reduction of the Aggregate Commitments. Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Lender according to its Applicable Percentage. All fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

2.08 Repayment of Loans.

(a) The Borrower shall repay to the Lenders on the Maturity Date the aggregate principal amount of Committed Loans outstanding on such date.

(b) The Borrower shall repay each Swing Line Loan on the earlier to occur of (i) demand by the Swing Line Lender and (ii) the Maturity Date.

2.09 Interest.

(a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate; (ii) each Base Rate Committed Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate; and (iii) each Swing Line Loan shall bear interest on the outstanding principal

amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate.

(b) (i) If any amount of principal of any Loan is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(ii) If any amount (other than principal of any Loan) payable by the Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iii) Upon the request of the Required Lenders, while any Event of Default exists, the Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(iv) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

2.10 Fees. In addition to certain fees described in subsections (i) and (j) of Section 2.03:

(a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Applicable Percentage, a commitment fee equal to the Applicable Rate times the daily amount of the Available Borrowing Base. The commitment fee shall accrue at all times during the Availability Period, including at any time during which one or more of the conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the last day of the Availability Period. The commitment fee shall be calculated quarterly in arrears, and if there is any change in the Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect. For the purposes of computation of the Commitment Fee, Swing Line Loans shall not be counted as usage of the Aggregate Commitments.

(b) Other Fees. (i) The Borrower shall pay to the Arranger and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in the Fee

Letter. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

(ii) The Borrower shall pay to the Lenders such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

2.11 Computation of Interest and Fees. All computations of interest for Base Rate Loans when the Base Rate is determined by Bank of America’s “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 fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.13(a), bear interest for one day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

2.12 Evidence of Debt.

(a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto.

(b) In addition to the accounts and records referred to in subsection (a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swing Line Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.13 Payments Generally; Administrative Agent’s Clawback.

(a) General. All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office in Dollars and in immediately available funds not later than 2:00 p.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Applicable Percentage (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 2:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Committed Borrowing of Eurodollar Rate Loans (or, in the case of any Committed Borrowing of Base Rate Loans, prior to 12:00 noon on the date of such Committed Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of such Committed Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Committed Borrowing of Base Rate Loans, that such Lender has made such share available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Committed Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) 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, plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing, and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower 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 Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Committed Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Committed Loan included in such Committed Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(ii) Payments by Borrower; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the L/C Issuer

hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the L/C Issuer, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the L/C Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the L/C Issuer, in immediately available funds 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.

A notice of the Administrative Agent to any Lender or the Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

(c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made available to the Borrower by the Administrative Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest.

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Committed Loans, to fund participations in Letters of Credit and Swing Line Loans and to make payments pursuant to Section 10.04(c) are several and not joint. The failure of any Lender to make any Committed Loan, to fund any such participation or to make any payment under Section 10.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Committed Loan, to purchase its participation or to make its payment under Section 10.04(c).

(e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner.

2.14 Sharing of Payments by Lenders. 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 the Committed Loans made by it, or the participations in L/C Obligations or in Swing Line Loans held by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Committed Loans or participations and accrued interest thereon 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 Committed Loans and subparticipations in L/C Obligations and in Swing Line Loans 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 Committed Loans and other amounts owing them, provided that:

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

(ii) the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Committed Loans or subparticipations in L/C Obligations or Swing Line Loans to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this Section shall apply).

The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or L/C Issuer, 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 timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. Without limiting the provisions of subsection (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the L/C Issuer, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Lender or the L/C Issuer, as the case may be, and any penalties,

interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other 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 the Borrower by a Lender or the L/C Issuer (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the L/C Issuer, shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

(iv) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower to determine the withholding or deduction required to be made.

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

3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Committed Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted.

3.03 Inability to Determine Rates. If the Required Lenders determine that for any reason in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan, or (c) the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate

Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Committed Borrowing of Base Rate Loans in the amount specified therein.

3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

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

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement contemplated by Section 3.04(e)) or the L/C Issuer;

(ii) subject any Lender or the L/C Issuer to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Rate Loan made by it, or change the basis of taxation of payments to such Lender or the L/C Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 3.01 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or the L/C Issuer); or

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

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

(b) Capital Requirements. If any Lender or the L/C Issuer determines that any Change in Law affecting such Lender or the L/C Issuer or any Lending Office of such Lender or such Lender’s or the L/C Issuer’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the L/C Issuer’s capital or on the capital of such Lender’s or the L/C Issuer’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the L/C Issuer, to a level below that which such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding

company could have achieved but for such Change in Law (taking into consideration such Lender’s or the L/C Issuer’s policies and the policies of such Lender’s or the L/C Issuer’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the L/C Issuer or such Lender’s or the L/C Issuer’s holding company for any such reduction suffered.

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

(d) Delay in Requests. Failure or delay on the part of any Lender or the L/C Issuer to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of such Lender’s or the L/C Issuer’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender or the L/C Issuer, 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 L/C Issuer’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).

(e) Reserves on Eurodollar Rate Loans. The Borrower shall pay to each Lender, as long as such Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional interest on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Loan, provided the Borrower shall have received at least 10 days’ prior notice (with a copy to the Administrative Agent) of such additional interest from such Lender. If a Lender fails to give notice 10 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 10 days from receipt of such notice.

3.05 Compensation for Losses. 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 of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (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 a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan on the date or in the amount notified by the Borrower; or

(c) any assignment of a Eurodollar Rate Loan 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 10.13; including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. 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 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

3.06 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or 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 3.01, or if any Lender gives a notice pursuant to Section 3.02, then such Lender shall use reasonable efforts to designate a different Lending Office for funding or booking its Loans 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 3.01 or 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, 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.

(b) Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if 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 3.01, the Borrower may replace such Lender in accordance with Section 10.13.

3.07 Survival. All of the Borrower’s obligations under this Article III shall survive termination of the Aggregate Commitments and repayment of all other Obligations hereunder.

The Borrower has disclosed to the Administrative Agent and the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. No report, financial statement, certificate or other information furnished in writing by or on behalf of any Loan Party to the Administrative Agent or any Lender in connection with the transactions contemplated hereby and the negotiation of this Agreement or delivered hereunder or under any other Loan Document (in each case as modified or supplemented by other information so furnished) contains as of the date so furnished any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. There are no statements or conclusions in any Engineering Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that projections concerning volumes attributable to the Oil and Gas Properties and production and cost estimates contained in each Engineering Report are necessarily based upon professional opinions, estimates and projections and that the Borrower and the Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate.

5.16 Compliance with Laws. Each Loan Party and each Subsidiary thereof is in compliance in all material respects with the requirements of all Laws and all orders, writs, injunctions and decrees applicable to it or to its properties, except in such instances in which (a) such requirement of Law or order, writ, injunction or decree is being contested in good faith by appropriate proceedings diligently conducted or (b) the failure to comply therewith, either individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

5.17 Solvency. Each Loan Party is, individually and together with its Subsidiaries on a Consolidated basis, Solvent.

5.18 Casualty, Etc. Neither the businesses nor the properties of any Loan Party or any of its Subsidiaries are affected by any fire, explosion, accident, strike, lockout or other labor dispute, drought, storm, hail, earthquake, embargo, act of God or of the public enemy or other casualty (whether or not covered by insurance) that, either individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

5.19 Labor Matters.

There are no collective bargaining agreements or Multiemployer Plans covering the employees of the Borrower or any of its Subsidiaries as of the Closing Date and neither the Borrower nor any Subsidiary has suffered any strikes, walkouts, work stoppages or other material labor difficulty within the last five years that, either individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

5.20 Collateral Documents. The provisions of the Collateral Documents are effective to create in favor of the Administrative Agent for the benefit of the Secured Parties a legal, valid and enforceable first priority Lien (subject to Liens permitted by Section 7.01) on all right, title and interest of the respective Loan Parties in the Collateral described therein. Except as expressly contemplated hereby and by the Collateral Documents, no filing or other action will be necessary to perfect or protect such Liens.

5.21 Engineered Oil and Gas Properties.

(a) The Borrower or another Loan Party has good and defensible title to all Engineered Oil and Gas Properties, free and clear of all Liens except as permitted pursuant to Section 7.01 and Immaterial Title Deficiencies. With the exception of Immaterial Title Deficiencies, all such Oil and Gas Properties are valid, subsisting, and in full force and effect, and all material rentals, royalties, and other amounts due and payable in respect thereof have been duly paid. Without regard to any consent or non-consent provisions of any joint operating agreement covering any of the Loan Parties’ Proved Reserves, and with the exception of Immaterial Title Deficiencies, the Loan Parties’ share of (a) the costs for each Engineered Oil and Gas Property is not greater than the decimal fraction set forth in the most recent Engineering Report, before and after payout, as the case may be, and described therein by the respective designations “working interests,” “WI,” “gross working interest,” “GWI,” or similar terms, and (b) production from, allocated to, or attributed to each Engineered Oil and Gas Property is not less than the decimal fraction set forth in the most recent Engineering Report, before and after payout, as the case may be, and described therein by the designations “net revenue interest,” “NRI,” or similar terms.

Except to the extent constituting an Immaterial Title Deficiency, each well drilled in respect of each Engineered Oil and Gas Property described in the Engineering Report (y) is capable of, and is presently, producing Hydrocarbons in commercial quantities, and the applicable Loan Party is currently receiving payments for its share of production, with no material funds in respect of any thereof being presently held in suspense, other than any such funds being held in suspense pending delivery of appropriate division orders and other usual and customary suspense accounts, and (z) has been drilled, bottomed, completed, and operated in compliance in all material respects with all applicable Laws and no such well which is currently producing hydrocarbons is subject to any penalty in production by reason of such well having produced in excess of its allowable production. To Borrower’s knowledge, there are no unrecorded assignments or conveyances affecting the Engineered Oil and Gas Properties or any Loan Party’s interest therein that would result in the Borrower or its Subsidiaries having a WI or NRI that is less than the WI/NRI set forth in the Engineering Report, except the interests of Sierra Madera CO2 Pipeline LP and Symbol Energy Inc., which constitute Immaterial Title Deficiencies.

(b) The Engineered Oil and Gas Properties (and all properties unitized therewith) are, in all material respects, being (and, to the extent the same could materially and adversely affect the ownership or operation of the Engineered Oil and Gas Properties after the date hereof, to the applicable Loan Party’s knowledge, have in the past been) maintained, operated and developed in a good and workmanlike manner, in accordance with prudent industry standards and in conformity with all applicable Laws and in conformity with all oil, gas or other mineral leases and other contracts and agreements forming a part of the Engineered Oil and Gas Property and in conformity with the Permitted Encumbrances. No Engineered Oil and Gas Property is subject to having allowable production after the date hereof reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) prior to the date hereof and (ii) none of the xxxxx located on the Engineered Oil and Gas Properties (or properties unitized therewith) are or will be deviated from the vertical more than the maximum permitted by applicable laws, regulations, rules and orders, and such xxxxx are bottomed under and producing from, with the well bores wholly within, the Engineered Oil and Gas Properties (or, in the case of xxxxx located on properties unitized therewith, such unitized properties). There are no dry holes, or otherwise inactive xxxxx, located on the Engineered Oil and Gas Properties or on lands pooled or unitized therewith, except for xxxxx that have been properly plugged and abandoned or for which appropriate plugging and abandonment has been scheduled. Each Loan Party has all material governmental licenses and permits reasonably necessary or appropriate to own and operate its Engineered Oil and Gas Properties, and no Loan Party has received notice in writing of any material violations in respect of any such licenses or permits.

5.22 Sale of Production. Except (x) as of the Closing Date, as set forth in Schedule 5.22, or (y) thereafter, as disclosed in writing to the Administrative Agent and the Lenders and reflected in the most recent determination of the Borrowing Base, or (z) for matters that constitute Immaterial Title Deficiencies:

(a) No Engineered Oil and Gas Property is subject to any material contractual or other arrangement (i) whereby payment for production is or can be deferred for a substantial period after the month in which such production is delivered (in the case of oil, not in excess of 60 days, and in the case of gas, not in excess of 90 days) or (ii) whereby payments are made to a Loan

Party other than by checks, drafts, wire transfer advises or other similar writings, instruments or communications for the immediate payment of money;

(b) (i) No Engineered Oil and Gas Property is subject to any material contractual or other arrangement for the sale, processing or transportation of production (or otherwise related to the marketing of production) which cannot be canceled on 120 days’ (or less) notice and (ii) all material contractual or other arrangements for the sale, processing or transportation of production (or otherwise related to the marketing of production) are bona fide arm’s length transactions made with third parties not affiliated with Loan Parties;

(c) Each Loan Party is presently receiving a price for all production (other than gas used for operations at a field location) from (or attributable to) each Engineered Oil and Gas Property covered by a production sales contract or marketing contract that is computed in accordance with the terms of such contract, and no Loan Party is having deliveries of production from such Engineered Oil and Gas Property curtailed substantially below such property’s delivery capacity, except for curtailments caused (i) by an act or event of force majeure, or (ii) by routine maintenance requirements in the ordinary course of business;

(d) No Loan Party, nor, to such Loan Party’s knowledge, any Loan Party’s predecessors in title, has received prepayments (including payments for gas not taken pursuant to “take or pay” or other similar arrangements) for any oil, gas or other hydrocarbons produced or to be produced from any Engineered Oil and Gas Properties after the date hereof;

(e) No Engineered Oil and Gas Property is subject to any “take or pay” or other similar arrangement (i) which can be satisfied in whole or in part by the production or transportation of gas from other properties or (ii) as a result of which production from any Engineered Oil and Gas Property may be required to be delivered to one or more third parties without payment (or without full payment) therefor as a result of payments made, or other actions taken, with respect to other properties;

(f) There is no Engineered Oil and Gas Property with respect to which any Loan Party, or, to such Loan Party’s knowledge, any Loan Party’s predecessors in title, has, prior to the date hereof, taken more (“overproduced”), or less (“underproduced”), in any material respect, gas from the lands covered thereby (or pooled or unitized therewith) than its ownership interest in such Engineered Oil and Gas Property would entitle it to take; and as of the Closing Date Schedule 5.22 accurately reflects, in all material respects, for each well or unit with respect to which such an imbalance is shown thereon to exist, (i) whether such Loan Party is overproduced or underproduced and (ii) the volumes (in cubic feet or British thermal units) of such overproduction or underproduction and the effective date of such information;

(g) No Engineered Oil and Gas Property is subject to a gas balancing arrangement under which one or more third parties may take a portion of the production attributable to such Engineered Oil and Gas Property without payment (or without full payment) therefor as a result of production having been taken from, or as a result of other actions or inactions with respect to, other properties; and

(h) No Engineered Oil and Gas Property is subject at the present time to any regulatory refund obligation and, to such Loan Party’s knowledge, no facts exist which might cause the same to be imposed.

(b) declare the unpaid principal amount of all outstanding Loans, all interest accrued and unpaid thereon, and all other amounts owing or payable hereunder or under any other Loan Document to be immediately due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by the Borrower;

(c) require that the Borrower Cash Collateralize the L/C Obligations (in an amount equal to the then Outstanding Amount thereof); and

(d) exercise on behalf of itself, the Lenders and the L/C Issuer all rights and remedies available to it, the Lenders and the L/C Issuer under the Loan Documents;

provided, however, that upon the occurrence of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States, the obligation of each Lender to make Loans and any obligation of the L/C Issuer to make L/C Credit Extensions shall automatically terminate, the unpaid principal amount of all outstanding Loans and all interest and other amounts as aforesaid shall automatically become due and payable, and the obligation of the Borrower to Cash Collateralize the L/C Obligations as aforesaid shall automatically become effective, in each case without further act of the Administrative Agent or any Lender.

8.03 Application of Funds. After the exercise of remedies provided for in Section 8.02 (or after the Loans have automatically become immediately due and payable and the L/C Obligations have automatically been required to be Cash Collateralized as set forth in the proviso to Section 8.02), any amounts received on account of the Obligations shall be applied by the Administrative Agent in the following order:

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including fees, charges and disbursements of counsel to the Administrative Agent and amounts payable under Article III) payable to the Administrative Agent in its capacity as such;

Second, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than principal, interest and Letter of Credit Fees) payable to the Lenders and the L/C Issuer (including fees, charges and disbursements of counsel to the respective Lenders and the L/C Issuer (including fees and time charges for attorneys who may be employees of any Lender or the L/C Issuer) and amounts payable under Article III), ratably among them in proportion to the respective amounts described in this clause Second payable to them;

Third, to payment of that portion of the Obligations constituting accrued and unpaid Letter of Credit Fees and interest on the Loans, L/C Borrowings and other Obligations, ratably among the Lenders and the L/C Issuer in proportion to the respective amounts described in this clause Third payable to them;

Fourth, to payment of that portion of the Obligations constituting unpaid principal of the Loans and L/C Borrowings and amounts payable under Swap Contracts, ratably among the Lenders, the L/C Issuer and the Lender Counterparties in proportion to the respective amounts described in this clause Fourth held by them;

Fifth, to the Administrative Agent for the account of the L/C Issuer, to Cash Collateralize that portion of L/C Obligations comprised of the aggregate undrawn amount of Letters of Credit; and

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required by Law.

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate undrawn amount of Letters of Credit pursuant to clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above.

ARTICLE IX.

ADMINISTRATIVE AGENT

9.01 Appointment and Authority.

(a) Each of the Lenders and the L/C Issuer hereby irrevocably appoints Bank of America to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Except to the extent Sections 9.01(b) and 9.06 expressly contemplate rights of others, the provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the L/C Issuer, and the Borrower shall not have rights as a third party beneficiary of any of such provisions.

(b) The Administrative Agent shall also act as the “collateral agent” under the Loan Documents, and each of the Lenders (in its capacities as a Lender and potential Lender Counterparty) and the L/C Issuer hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and the L/C Issuer for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 9.05 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and remedies thereunder at the

direction of the Administrative Agent), shall be entitled to the benefits of all provisions of this Article IX and Article X (including Section 10.04(c), as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto.

9.02 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

9.03 Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 10.01 and 8.02) or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by the Borrower, a Lender or the L/C Issuer.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this

Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or the creation, perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the value or the sufficiency of any Collateral, or (vi) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

9.04 Reliance by Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or the L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or the L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

9.05 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

9.06 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders, the L/C Issuer and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the L/C Issuer, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has

accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders or the L/C Issuer under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also constitute its resignation as L/C Issuer and Swing Line Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer and Swing Line Lender, (b) the retiring L/C Issuer and Swing Line Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit.

9.07 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the L/C Issuer acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the L/C Issuer also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, the Arranger shall have no powers, duties or responsibilities under this Agreement.

9.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer and the Administrative Agent under Sections 2.03(i) and (j), 2.09 and 10.04) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the L/C Issuer, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.09 and 10.04.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the L/C Issuer any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or the L/C Issuer to authorize the Administrative Agent to vote in respect of the claim of any Lender or the L/C Issuer in any such proceeding.

9.10 Collateral and Guaranty Matters. The Lenders and the L/C Issuer irrevocably authorize the Administrative Agent, at its option and in its discretion,

(a) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (i) upon termination of the Aggregate Commitments and payment in full of all Obligations (other than contingent indemnification obligations and obligations with respect to Swap Contracts) and the expiration or termination of all Letters of Credit, (ii) that is Disposed of or to be Disposed of as part of or in connection with any Disposition permitted hereunder or under any other Loan Document, or (iii) subject to Section 10.01, if approved, authorized or ratified in writing by the Required Lenders;

(b) to subordinate or release any Lien on any property granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by Section 7.01(i); and

(c) to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty pursuant to this Section 9.10. In each case as specified in this Section 9.10, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Collateral Documents or to subordinate its interest in such item, or to release such Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section 9.10.

(c) Reimbursement by Lenders. To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by it to the Administrative Agent (or any sub-agent thereof), the L/C Issuer or any Related Party of any of the foregoing, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent), the L/C Issuer or such Related Party, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) or the L/C Issuer in its

capacity as such, or against any Related Party of any of the foregoing acting for the Administrative Agent (or any such sub-agent) or L/C Issuer in connection with such capacity. The obligations of the Lenders under this subsection (c) are subject to the provisions of Section 2.13(d).

(d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in subsection (b) 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.

(e) Payments. All amounts due under this Section shall be payable not later than ten Business Days after demand therefor.

(f) Survival. The agreements in this Section shall survive the resignation of the Administrative Agent, the L/C Issuer and the Swing Line Lender, the replacement of any Lender, the termination of the Aggregate Commitments and the repayment, satisfaction or discharge of all the other Obligations.

10.05 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to the Administrative Agent, the L/C Issuer or any Lender, or the Administrative Agent, the L/C Issuer or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent, the L/C Issuer or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender and the L/C Issuer severally agrees to pay to the Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders and the L/C Issuer under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

10.06 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section, or (iv) to an SPC in accordance with the provisions of subsection (h) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the L/C Issuer and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans (including for purposes of this subsection (b), participations in L/C Obligations and in Swing Line Loans) at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single assignee (or to an assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met..

100

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned, except that this clause (ii) shall not apply to the Swing Line Lender’s rights and obligations in respect of Swing Line Loans;

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

(C) the consent of the L/C Issuer and the Swing Line Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount, if any, required as set forth in Schedule 10.06; provided, however, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning 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 3.01, 3.04, 3.05, and 10.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee

101

Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection 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 subsection (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in L/C Obligations and/or Swing Line Loans) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Lenders and the L/C Issuer shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.01 that affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.14 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 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 3.01 unless the Borrower is notified of the participation sold to such Participant and

102

such Participant agrees, for the benefit of the Borrower, to comply with Section 3.01(e) as though it were a Lender.

(f) 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 (including under its Note, if any) 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.

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

(h) Special Purpose Funding Vehicles. Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Committed Loan that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Committed Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Committed Loan, the Granting Lender shall be obligated to make such Committed Loan pursuant to the terms hereof or, if it fails to do so, to make such payment to the Administrative Agent as is required under Section 2.13(b)(ii). Each party hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall increase the costs or expenses or otherwise increase or change the obligations of the Borrower under this Agreement (including its obligations under Section 3.04), (ii) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, and (iii) the Granting Lender shall for all purposes, including the approval of any amendment, waiver or other modification of any provision of any Loan Document, remain the lender of record hereunder. The making of a Committed Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Committed Loan were made by such Granting Lender. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior debt of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained herein, any SPC may (i) with notice to, but without prior consent of the Borrower and the Administrative Agent and with the payment of a processing fee in the amount of $2,500, assign all or any portion of its right to receive payment with respect to any Committed Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information

103

relating to its funding of Committed Loans to any rating agency, commercial paper dealer or provider of any surety or Guarantee or credit or liquidity enhancement to such SPC.

(i) Resignation as L/C Issuer or Swing Line Lender after Assignment. Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Commitment and Loans pursuant to subsection (b) above, Bank of America may, (i) upon 30 days’ notice to the Borrower and the Lenders, resign as L/C Issuer and/or (ii) upon 30 days’ notice to the Borrower, resign as Swing Line Lender.. In the event of any such resignation as L/C Issuer or Swing Line Lender, the Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer or Swing Line Lender hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Bank of America as L/C Issuer or Swing Line Lender, as the case may be. If Bank of America resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Committed Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)). If Bank of America resigns as Swing Line Lender, it shall retain all the rights of the Swing Line Lender provided for hereunder with respect to Swing Line Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Committed Loans or fund risk participations in outstanding Swing Line Loans pursuant to Section 2.04(c). Upon the appointment of a successor L/C Issuer and/or Swing Line Lender, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swing Line Lender, as the case may be, and (b) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

10.07 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Lenders and the L/C Issuer agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or

104

(y) becomes available to the Administrative Agent, any Lender, the L/C Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower.

For purposes of this Section, “Information” means all information received from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the L/C Issuer on a nonconfidential basis prior to disclosure by the Borrower or any Subsidiary, provided that, in the case of information received from the Borrower or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as nonpublic and confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to confidential information of a similar nature.

Each of the Administrative Agent, the Lenders and the L/C Issuer acknowledges that (a) the Information may include material non-public information concerning the Borrower or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use of material non-public information and (c) it will handle such material non-public information in accordance with applicable Law, including Federal and state securities Laws.

10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender, the L/C Issuer and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the L/C Issuer or any such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or the L/C Issuer, irrespective of whether or not such Lender or the L/C Issuer shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower may be contingent or unmatured or are owed to a branch or office of such Lender or the L/C Issuer different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender, the L/C Issuer and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Issuer or their respective Affiliates may have. Each Lender and the L/C Issuer agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

10.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude

105

voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

10.10 Counterparts; Integration; Effectiveness.This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof and, except as otherwise expressly provided in the Commitment Letter, supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

10.11 Survival of Representations and Warranties.All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

10.12 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.13 Replacement of Lenders. If (i) any Lender requests compensation under Section 3.04, (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 3.01, (iii) any Lender is a Defaulting Lender, or (iv) any Lender is unwilling to approve an increase in the Borrowing Base or other amendment hereto which has been approved by Super-Majority Lenders but requires approval of such Lender to be effective, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.06), all of its interests, rights and obligations under this

106

Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(a) the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 10.06(b);

(b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(c) in the case of any such assignment resulting from a claim for compensation under Section 3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter;

(d) in the case of an assignment resulting from clause (iv) above, such assignment will result in effectiveness of such increase or amendment; and

(e) such assignment does not conflict with applicable Laws.

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

10.14 Governing Law; Jurisdiction; Etc.

(a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

(b) SUBMISSION TO JURISDICTION. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT.

NOTHING IN THIS AGREEMENT OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE ADMINISTRATIVE AGENT, ANY LENDER OR THE L/C ISSUER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO

107

THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

(c) WAIVER OF VENUE. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION.

EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

10.16 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby, the Borrower acknowledges and agrees that: (i) the credit facility provided for hereunder and any related arranging or other services in connection therewith (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document) are an arm’s-length commercial transaction between the Borrower and its Affiliates, on the one hand, and the Administrative Agent and the Arranger, on the other hand, and the Borrower is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents (including any amendment, waiver or other modification hereof or thereof); (ii) in connection with the process leading to such transaction, the Administrative Agent and the Arranger each is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary, for the Borrower or any of its Affiliates, stockholders, creditors or employees or any other Person; (iii) neither the Administrative Agent nor the Arranger has assumed or will assume

108

an advisory, agency or fiduciary responsibility in favor of the Borrower with respect to any of the transactions contemplated hereby or the process leading thereto, including with respect to any amendment, waiver or other modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent or the Arranger has advised or is currently advising the Borrower or any of its Affiliates on other matters) and neither the Administrative Agent nor the Arranger has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; (iv) the Administrative Agent and the Arranger and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and neither the Administrative Agent nor the Arranger has any obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Administrative Agent and the Arranger have not provided and will not provide any legal, accounting, regulatory or tax advice with respect to any of the transactions contemplated hereby (including any amendment, waiver or other modification hereof or of any other Loan Document) and the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate.

GUARANTY

GUARANTY dated as of November 21, 2006 made by the Persons listed on the signature pages hereof and the Additional Guarantors (as defined in Section 8(b)) (such Persons so listed and the Additional Guarantors being, collectively, the “Guarantors” and, individually, each a “Guarantor”) in favor of the Guaranteed Parties (as defined below).

PRELIMINARY STATEMENT. Riata Energy Inc. (d/b/a XxxxXxxxx Energy Inc.), a Texas Corporation (the “Borrower”), is party to a Credit Agreement dated as of November 21, 2006 (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms defined therein and not otherwise defined herein being used herein as therein defined) with certain Lenders party thereto, Bank of America, N.A., as administrative agent (the “Administrative Agent”), L/C Issuer and Swing Line Lender. Each Guarantor may receive, directly or indirectly, a portion of the proceeds of the Loans under the Credit Agreement and will derive substantial direct and indirect benefits from the transactions contemplated by the Credit Agreement. It is a condition precedent to the making of Loans and the issuance of Letters of Credit by the Guaranteed Parties under the Credit Agreement that each Guarantor shall have executed and delivered this Guaranty. The Lenders, the Administrative Agent, the Swing Line Lender, the L/C Issuer and Lender Counterparties are herein called the “Guaranteed Parties”.

NOW, THEREFORE, in consideration of the premises and in order to induce the Guaranteed Parties to enter into, and to make Loans and to issue Letters of Credit under, the Credit Agreement and to enter into Swap Contracts with Lender Counterparties from time to time, each Guarantor, jointly and severally with each other Guarantor, agrees as follows:

Section 1. Guaranty; Limitation of Liability. (a) Each Guarantor absolutely, unconditionally and irrevocably guarantees the punctual payment when due, whether at scheduled maturity or on any date of a required prepayment or by acceleration, demand or otherwise, of all Obligations of each other Loan Party (such Obligations being the “Guaranteed Obligations”), and will pay any and all expenses (including fees and expenses of counsel) incurred by the Administrative Agent or any other Guaranteed Party in enforcing any rights under this Guaranty, any other Loan Document or any Swap Contract with a Lender Counterparty. Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other Loan Party to any Guaranteed Party but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party.

(b) Each Guarantor and by its acceptance of this Guaranty the Administrative Agent and each other Guaranteed Party, confirm that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law (as hereinafter defined), the Uniform

Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the Obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the other Guaranteed Parties and the Guarantors irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance. For purposes hereof, “Bankruptcy Law” means law with respect to any proceeding of the type referred to in Section 8.01(f) of the Credit Agreement or Title 11, U.S. Code, or any similar foreign, federal or state law for the relief of debtors.

(c) If any payment shall be required to be made to any Guaranteed Party under this Guaranty or any other guaranty, then, subject to Section 4, each Guarantor will contribute, to the maximum extent permitted by law, such amounts to each other Guarantor and each other guarantor so as to maximize the aggregate amount paid to the Guaranteed Parties under or in respect of the Loan Documents and Swap Contracts with Lender Counterparties.

Section 2. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents and Swap Contracts with Lender Counterparties, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Guaranteed Party with respect thereto. The Obligations of each Guarantor under or in respect of this Guaranty are independent of the Guaranteed Obligations or any other obligations of any other Loan Party arising under the Loan Documents or otherwise with respect to any Loan or Letter of Credit or any Swap Contract with a Lender Counterparty, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Borrower or any other Loan Party or whether the Borrower or any other Loan Party is joined in any such action or actions. The liability of each Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of any Loan Document or any Swap Contract with a Lender Counterparty or any agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, of any other Loan Party under or in respect of the Loan Documents or Swap Contracts with Lender Counterparties, or any other amendment or waiver of or any consent to departure from any Loan Document or Swap Contract with a Lender Counterparty, including any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise;

(c) any taking, exchange, release or non-perfection of any Collateral or any other collateral, or any taking, release or amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Guaranteed Obligations;

(d) any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Guaranteed Obligations or any other obligations of any Loan Party arising under the Loan Documents or otherwise with respect to any Loan or Letter of Credit or any Swap Contract with a Lender Counterparty or any other assets of any Loan Party or any of its Subsidiaries;

(e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries;

(f) any failure of any Guaranteed Party to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to such Guaranteed Party;

(g) the failure of any other Person to execute or deliver this Guaranty, any Guaranty Supplement (as hereinafter defined) or any other guaranty or agreement or the release or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or

(h) any other circumstance (including any statute of limitations) or any existence of or reliance on any representation by any Guaranteed Party that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Guaranteed Party or any other Person upon the insolvency, bankruptcy or reorganization of the Borrower or any other Loan Party or otherwise, all as though such payment had been due but not made at such time.

Section 3. Waivers and Acknowledgments. (a) Each Guarantor unconditionally and irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that any Guaranteed Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against any Loan Party or any other Person or any Collateral.

(b) Each Guarantor unconditionally and irrevocably waives any right to revoke this Guaranty and acknowledges that this Guaranty is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future.

(i) any defense arising by reason of any claim or defense based upon an election of remedies by any Guaranteed Party that in any manner impairs, reduces,

releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Guarantor or other rights of such Guarantor to proceed against any of the other Loan Parties, any other guarantor or any other Person or any Collateral, and

(ii) any defense based on any right of set-off or counterclaim against or in respect of the Obligations of such Guarantor hereunder.

(d) Each Guarantor acknowledges that the Administrative Agent may, without notice to or demand upon such Guarantor and without affecting the liability of such Guarantor under this Guaranty, foreclose under any mortgage or other security agreement by non-judicial sale, and each Guarantor hereby waives any defense to the recovery by the Administrative Agent and the other Guaranteed Parties against such Guarantor of any deficiency after such non-judicial sale and any defense or benefits that may be afforded by applicable law.

(e) Each Guarantor unconditionally and irrevocably waives any duty on the part of any Guaranteed Party to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party or any of its Subsidiaries now or hereafter known by such Guaranteed Party.

(f) Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Loan Documents and Swap Contracts with Lender Counterparties and that the waivers set forth in Section 2 and this Section 3 are knowingly made in contemplation of such benefits and it has determined that this Guaranty is necessary and convenient to the conduct, promotion and attainment of the business of such Guarantor.

Section 4. Subrogation. Each Guarantor unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower, any other Loan Party or any other insider guarantor that arise from the existence, payment, performance or enforcement of such Guarantor’s Obligations under or in respect of this Guaranty or any other Loan Document or obligations under Swap Contracts with Lender Counterparties, including any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Guaranteed Party against the Borrower, any other Loan Party or any other insider guarantor or any Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including the right to take or receive from the Borrower, any other Loan Party or any other insider guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash, all Letters of Credit and all Swap Contracts with Lender Counterparties shall have expired or been terminated or cash collateralized to the satisfaction of the LC Issuer or the Lender Counterparty, as the case may be, and the Commitments shall have expired or been terminated. If any amount shall be paid to any Guarantor in violation of the immediately preceding sentence at any time prior to the latest of:

(a) the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty,

(b) the irrevocable termination or expiration in whole of all Commitments and

(c) the latest date of expiration or termination of all Letters of Credit and all Swap Contracts with Lender Counterparties,

such amount shall be received and held in trust for the benefit of the Guaranteed Parties, shall be segregated from other property and funds of such Guarantor and shall forthwith be paid or delivered to the Administrative Agent in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the Loan Documents and the Swap Contracts with Lender Counterparties, or to be held as Collateral for any Guaranteed Obligations or other amounts payable under this Guaranty thereafter arising. If:

(i) any Guarantor shall make payment to any Guaranteed Party of all or any part of the Guaranteed Obligations,

(ii) all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash,

(iii) all Commitments shall have been irrevocably terminated or shall have irrevocably expired in whole and

(iv) all Letters of Credit and all Swap Contracts with Lender Counterparties shall have expired or been terminated or cash collateralized to the satisfaction of the LC Issuer or the Lender Counterparty, as the case may be,

the Guaranteed Parties will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment or other condition made by such Guarantor pursuant to this Guaranty.

Section 5. Payments Free and Clear of Taxes, Etc.

(a) Any and all payments by or on account of any obligation of any Guarantor hereunder or under any other Loan Document or Swap Contracts with Lender Counterparties shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes; provided that if a Guarantor shall be required by applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, the LC Issuer, or the Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Guarantor shall make such deductions and

(iii) such Guarantor shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Without limiting the provisions of subsection (a) above, each Guarantor shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Each Guarantor shall indemnify each Guaranteed Party, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes which (i) arise from any payment made hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and (ii) are paid by such Guaranteed Party, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority but net of any foreign tax credit or the benefit of any deduction or other tax benefit determined in good faith by such Guaranteed Party to be attributable to the imposition of such Indemnified Tax. A certificate as to the amount of such payment or liability delivered in good faith to a Guarantor by a Guaranteed Party (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Guaranteed Party, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a guarantor to a Governmental Authority, such Guarantor shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which a Guarantor is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document or any Swap Contracts with Lender Counterparties shall deliver to such Guarantor (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by a Guarantor or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by a Guarantor or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by such Guarantor or the Administrative Agent as will enable such Guarantor or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

(f) Without limiting the generality of the foregoing, in the event that a Guarantor is resident for tax purposes in the United States of America, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under the Credit Agreement (and from time to time thereafter upon the request of the

Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States of America is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN or

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

Section 6. Representations and Warranties. Each Guarantor makes each representation and warranty made in the Loan Documents and Swap Contracts with Lender Counterparties by the Borrower with respect to such Guarantor and each Guarantor hereby further represents and warrants as follows:

(a) There are no conditions precedent to the effectiveness of this Guaranty that have not been satisfied or waived.

(b) Such Guarantor has, independently and without reliance upon any Guaranteed Party and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Guaranty and each other Loan Document to which it is or is to be a party, and such Guarantor has established adequate means of obtaining from each other Loan Party on a continuing basis information pertaining to, and is now and on a continuing basis will be completely familiar with, the business, condition (financial or otherwise), operations, performance, properties and prospects of such other Loan Party.

Section 7. Covenants. So long as any part of the Guaranteed Obligations shall remain unpaid, any Letter of Credit shall be outstanding, any Guaranteed Party shall have any Commitment or any Swap Contract with a Lender Counterparty shall be in effect, each Guarantor will perform and observe, and cause each of its Subsidiaries to perform and observe, all of the terms, covenants and agreements set forth in the Loan Documents and Swap Contracts with Lender Counterparties on its or their part to be performed or observed or that the Borrower has agreed to cause such Guarantor or such Subsidiaries to perform or observe.

Section 8. Amendments, Guaranty Supplements, Etc. (a) No amendment or waiver of any provision of this Guaranty and no consent to any departure by any Guarantor herefrom shall in any event be effective unless the same shall be entered into in accordance with Section 10.01 of the Credit Agreement.

(b) Upon the execution and delivery by any Person of a guaranty supplement in substantially the form of Exhibit A hereto (each, a “Guaranty Supplement”), (i) such Person shall be referred to as an “Additional Guarantor” and shall become and be a Guarantor hereunder, and each reference in this Guaranty to a “Guarantor” shall also mean and be a reference to such Additional Guarantor, and each reference in any other Loan Document to a “Subsidiary Guarantor” shall also mean and be a reference to such Additional Guarantor, and (ii) each reference herein to “this Guaranty”, “hereunder”, “hereof” or words of like import referring to this Guaranty, and each reference in any other Loan Document to the “Guaranty”, “thereunder”, “thereof” or words of like import referring to this Guaranty, shall mean and be a reference to this Guaranty as supplemented by such Guaranty Supplement and all other Guaranty Supplements.

Section 9. Notices, Etc. All notices and other communications provided for hereunder shall be in writing (including telecopy communication) and mailed, telecopied, or delivered to it, if to any Guarantor, addressed to it in care of the Borrower at the Borrower’s address in accordance with Section 10.02 of the Credit Agreement, if to the Administrative Agent or any other Guaranteed Party, at its address in accordance with Section 10.02 of the Credit Agreement, or, as to any party, at such other address as shall be designated by such party in a written notice to each other party. All such notices and other communications shall, when mailed or telecopied, be effective when deposited in the mails or transmitted by telecopier, respectively. Delivery of an executed counterpart of a signature page to any amendment or waiver of any provision of this Guaranty or of any Guaranty Supplement by telecopier shall be effective as delivery of an original executed counterpart thereof.

Section 10. No Waiver; Remedies. No failure on the part of any Guaranteed Party to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder 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 11. Right of Set-off. To secure the repayment of the Guaranteed Obligations, each Guarantor grants to each Guaranteed Party, and each of their respective Affiliates, a security interest, a lien, and a right of offset, each of which shall be in addition to all other interests, liens, and rights of any Guaranteed Party, at common Law, under the Loan Documents and Swap Contracts with Lender Counterparties, or otherwise, and each of which shall be upon and against:

(a) any and all moneys, securities or other property (and the proceeds therefrom) of such Guarantor now or hereafter held or received by or in transit to any Guaranteed Party, from or for the account of such Guarantor, whether for safekeeping, custody, pledge, transmission, collection or otherwise,

(b) any and all deposits (general or special, time or demand, provisional or final) of such Guarantor with any Guaranteed Party, or any of their respective Affiliates and

(c) any other credits and claims of Borrower at any time existing against any Guaranteed Party, including claims under certificates of deposit. At any time and from time to time after the occurrence of any Event of Default, each Guaranteed Party is authorized to foreclose upon, or to offset against the Guaranteed Obligations then due and payable (in either case without notice to such Guarantor), any and all items hereinabove referred to; irrespective of whether or not such Guaranteed Party shall have made any demand under this Guaranty, any other Loan Document or any Swap Contracts with Lender Counterparties and although such obligations of such Guarantor may be contingent or unmatured or are owed to a branch or office of such Guaranteed Party different from the branch or office holding such items.

The remedies of foreclosure and offset are separate and cumulative, and either may be exercised independently of the other without regard to procedures or restrictions applicable to the other..

Section 12. Subordination. Each Guarantor subordinates any and all debts, liabilities and other Obligations owed to such Guarantor by each other Loan Party (the “Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner hereinafter set forth in this Section 12:

(a) Except during the continuance of an Event of Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), each Guarantor may receive regularly scheduled payments from any other Loan Party on account of the Subordinated Obligations. After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan

Party), however, unless the Administrative Agent otherwise agrees, no Guarantor shall demand, accept or take any action to collect any payment on account of the Subordinated Obligations.

(b) In any proceeding under any Bankruptcy Law relating to any other Loan Party, the Guaranteed Parties shall be entitled to receive payment in full in cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post Petition Interest”)) before such Guarantor receives payment of any Subordinated Obligations.

(c) After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), each Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for the Guaranteed Parties and deliver such payments to the Administrative Agent on account of the Guaranteed Obligations (including all Post Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Guaranty.

(d) After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), the Administrative Agent is authorized and empowered (but without any obligation to so do), in its discretion:

(i) in the name of each Guarantor, to collect and enforce, and to submit claims in respect of, Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post Petition Interest), and

(ii) to require each Guarantor (A) to collect and enforce, and to submit claims in respect of, Subordinated Obligations and (B) to pay any amounts received on such obligations to the Administrative Agent for application to the Guaranteed Obligations (including any and all Post Petition Interest).

Section 13. Continuing Guaranty; Assignments under the Credit Agreement. This Guaranty is a continuing guaranty and shall:

(a) remain in full force and effect until it is released in accordance with the Credit Agreement,

(b) be binding upon the Guarantor, its successors and assigns and

(c) inure to the benefit of and be enforceable by the Guaranteed Parties and their permitted successors, transferees and assigns.

Without limiting the generality of clause (c) of the immediately preceding sentence, any Guaranteed Party may assign or otherwise transfer all or any portion of its rights and obligations under the Credit Agreement (including all or any portion of its Commitments, the Loans owing to it and the Note or Notes held by it) or Swap Contracts with Lender Counterparties to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Guaranteed Party herein or otherwise, in each case as and to the extent provided in Section 10.06 of the Credit Agreement in the case of Loans and Commitments or the applicable Swap Contract in the case of a Swap Contract. No Guarantor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Guaranteed Parties.

Section 14. Execution in Counterparts.

Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other Loan Party to any Guaranteed Party but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party.

(b) The undersigned, and by their acceptance of this Guaranty Supplement, the Administrative Agent and each other Guaranteed Party, confirm that it is the intention of all such Persons that this Guaranty Supplement, the Guaranty and the Obligations of the undersigned hereunder and thereunder not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty Supplement, the Guaranty and the Obligations of the undersigned hereunder and thereunder. To

(c) If any payment shall be required to be made to any Guaranteed Party under this Guaranty Supplement, the Guaranty or any other guaranty, then, subject to Section 4, the undersigned will contribute, to the maximum extent permitted by applicable law, such amounts to each other Guarantor and each other guarantor so as to maximize the aggregate amount paid to the Guaranteed Parties under or in respect of the Loan Documents and Swap Contracts with Lender Counterparties.

Section 2. Obligations Under the Guaranty. The undersigned hereby agrees, as of the date first-above written, to be bound as a Guarantor by all of the terms and conditions of the Guaranty to the same extent as each of the other Guarantors thereunder. The undersigned further agrees, as of the date first above written, that each reference in the Subsidiary Guaranty to an “Additional Guarantor” or a “Guarantor” shall also mean and be a reference to the undersigned, and each reference in any other Loan Document to a “Guarantor” or a “Loan Party” shall also mean and be a reference to the undersigned.

Section 3. Representations and Warranties. As of the date first-above written, the undersigned makes each representation and warranty set forth in Section 6 of the Guaranty to the same extent as each other Guarantor.

Section 4. Delivery by Telecopier. Delivery of an executed counterpart of a signature page to this Guaranty Supplement by telecopier shall be effective as delivery of an original executed counterpart of this Guaranty Supplement.

Section 5. Governing Law; Jurisdiction; Waiver of Jury Trial, Etc. (a) THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

(b) THE UNDERSIGNED IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY SUPPLEMENT, THE GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY SWAP CONTRACT WITH A LENDER COUNTERPARTY, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND THE UNDERSIGNED IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN

A-2

SUCH FEDERAL COURT. THE UNDERSIGNED 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 GUARANTY SUPPLEMENT, THE GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY SWAP CONTRACT WITH A LENDER COUNTERPARTY SHALL AFFECT ANY RIGHT THAT ANY GUARANTEED PARTY MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS GUARANTY SUPPLEMENT, THE GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY SWAP CONTRACT WITH A LENDER COUNTERPARTY AGAINST THE UNDERSIGNED OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

(c) THE UNDERSIGNED IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY SUPPLEMENT, THE GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY SWAP CONTRACT WITH A LENDER COUNTERPARTY IN ANY COURT REFERRED TO IN SUBSECTION (b) ABOVE. THE UNDERSIGNED IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

(d) THE UNDERSIGNED IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 9 OF THE GUARANTY. NOTHING IN THIS GUARANTY SUPPLEMENT OR THE GUARANTY WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

SECURITY AGREEMENT

SECURITY AGREEMENT dated as of November 21, 2006 made by RIATA ENERGY INC., a Texas corporation (d/b/a XxxxXxxxx Energy Inc.) (the “Borrower”), the other Persons listed on the signature pages hereof and the Additional Grantors (as defined in Section 18) (the Borrower, the Persons so listed and the Additional Grantors being collectively the “Grantors”), to BANK OF AMERICA, N.A.., as administrative agent (the “Administrative Agent”) for the Secured Parties (as hereinafter defined)).

PRELIMINARY STATEMENTS.

(1) The Borrower has entered into the Credit Agreement dated as of November 21, 2006 (as amended, restated, supplemented, or otherwise modified from time to time, the “Credit Agreement”; capitalized terms defined therein and not otherwise defined herein being used herein as therein defined) with certain Lenders party thereto and Bank of America, N.A., as administrative agent (the “Administrative Agent”).

(2) As contemplated in the Credit Agreement, the Grantors owe, and may hereafter owe Obligations to Lender Counterparties. The Swap Contracts under which such Obligations are owed are herein called the “Lender Hedging Contracts”.

(3) The Grantors are entering into this Agreement in order to grant to the Administrative Agent for the ratable benefit of the Secured Parties a security interest in the Collateral (as hereinafter defined).

(4) Each Grantor is the owner of the shares of stock or other Equity Interests (the “Initial Pledged Equity”) set forth opposite such Grantor’s name on and as otherwise described in Schedule II hereto and issued by the Persons named therein.

(5) It is a condition precedent to the making of Loans and the issuance of Letters of Credit by the Secured Parties under the Credit Agreement and the entry into Lender Hedging Contracts from time to time, that the Grantors shall have granted the assignment and security interest and made the pledge and assignment contemplated by this Agreement.

(6) Each Grantor will derive substantial direct and indirect benefit from the transactions contemplated by the Loan Documents and the Lender Hedging Contracts.

(7) Unless otherwise defined in this Agreement or in the Credit Agreement, terms defined in Article 8 or 9 of the UCC (as defined below) and/or in the Federal Book Entry Regulations (as defined below) are used in this Agreement as such terms are defined in such Article 8 or 9 and/or the Federal Book Entry Regulations. “UCC” means the Uniform Commercial Code as in effect, from time to time, in the State of New York; provided that, if perfection or the effect of perfection or non-perfection or the priority of any security interest in any Collateral is governed by the Uniform Commercial Code as in effect in a jurisdiction other than the State of New York, “UCC” means the Uniform Commercial Code as in effect from time to time in such other jurisdiction for purposes of the provisions hereof relating to such perfection, effect of perfection or non-perfection or priority. “Federal Book Entry Regulations” means (a)

the federal regulations contained in Subpart B (“Treasury/Reserve Automated Debt Entry System (TRADES)”) governing book-entry securities consisting of U.S. Treasury bonds, notes and bills and Subpart D (“Additional Provisions”) of 31 C.F.R. Part 357, 31 C.F.R. § 357.2, § 357.10 through § 357.14 and § 357.41 through § 357.44 and (b) to the extent substantially identical to the federal regulations referred to in clause (a) above (as in effect from time to time), the federal regulations governing other book-entry securities.

NOW, THEREFORE, in consideration of the premises and in order to induce the Secured Parties to make Loans and issue Letters of Credit under the Credit Agreement and to induce the Secured Parties to ender into the Lender Hedging Contracts from time to time, each Grantor agrees with the Administrative Agent for the ratable benefit of the Secured Parties as follows:

provided that the following property is excluded from the foregoing security interests: (A) voting Equity Interests in any CFC, to the extent (but only to the extent) required to prevent the Collateral from including more than 66% of all voting Equity Interests in such CFC, (B) Equipment leased by a Grantor under a lease or otherwise financed pursuant to a purchase-money financing arrangement that prohibits the granting of a Lien on such Equipment, (C) any general intangible, investment property or other rights arising under any contract, instrument, license or other document or under any law, regulation, permit, order or decree of any Governmental Authority if (but only to the extent that) the grant of a security interest therein

would constitute a violation of a legally effective restriction in respect of such general intangible, investment property or other rights in favor of a third party, unless and until all required consents shall have been obtained (for the avoidance of doubt, the restrictions described herein are not negative pledge or similar undertakings in favor of a lender or other financial counterparty), (D) Equity Interests in Cholla Pipeline, LP, Integra Energy, L.L.C. and Sagebrush Pipeline, LLC unless and until any requisite consent of other holders of Equity Interests therein are obtained and (E) to the extent that (and only to the extent that) the grant of a security interest therein would constitute a material violation of applicable Law, any other property (any and all such excluded property being the “Excluded Personal Property”). Each Grantor shall, if requested to do so by the Administrative Agent, use commercially reasonable efforts to obtain any such required consent that is reasonably obtainable with respect to Collateral which the Administrative Agent reasonably determines to be material.

Section 2. Security for Obligations. This Agreement secures, in the case of each Grantor, the payment of all Obligations of any Loan Party (all such Obligations being the “Secured Obligations”).

Section 3. Grantors Remain Liable. Anything herein to the contrary notwithstanding:

(a) each Grantor shall remain liable under the contracts and agreements included in such Grantor’s Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed;

(b) the exercise by the Administrative Agent of any of the rights hereunder shall not release any Grantor from any of its duties or obligations under the contracts and agreements included in the Collateral; and

(c) no Secured Party shall have any obligation or liability under the contracts and agreements included in the Collateral by reason of this Agreement, any other Loan Document or any Lender Hedging Contract, nor shall any Secured Party be obligated to perform any of the obligations or duties of any Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

Section 4. Delivery and Control of Security Collateral. (a) Subject to Section 4(i) below, all certificates or instruments representing or evidencing Security Collateral shall be delivered to and held by or on behalf of the Administrative Agent pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to the Administrative Agent. The Administrative Agent shall have the right, at any time in its discretion and without notice to any Grantor, to transfer to or to register in the name of the Administrative Agent or any of its nominees any or all of the Security Collateral, subject only to the revocable rights specified in Section 10(a). In addition, the Administrative Agent shall have the right, upon the occurrence and during the continuance of an Event of Default at any time to exchange certificates or instruments representing or evidencing Security Collateral for certificates or instruments of smaller or larger denominations.

(b) Subject to Section 4(i) below, with respect to any Security Collateral in which any Grantor has any right, title or interest and that constitutes an uncertificated security, such Grantor will cause the issuer thereof either:

(i) to register the Administrative Agent as the registered owner of such security or

(ii) to agree in an authenticated record with such Grantor and the Administrative Agent that such issuer will comply with instructions with respect to such security originated by the Administrative Agent without further consent of such Grantor, such authenticated record to be in form and substance satisfactory to the Administrative Agent.

With respect to any Security Collateral in which any Grantor has any right, title or interest and that is not an uncertificated security, upon the request of the Administrative Agent, such Grantor will notify each such issuer of Pledged Equity that such Pledged Equity is subject to the security interest granted hereunder. Each Grantor that is the issuer of any Security Collateral or Pledged Equity belonging to another Grantor acknowledges the security interest granted hereunder in such Security Collateral and will take the actions described above in this subsection (b).

(c) Subject to Section 4(i) below, with respect to any Security Collateral in which any Grantor has any right, title or interest and that constitutes a security entitlement in which the Administrative Agent is not the entitlement holder, such Grantor will cause the securities intermediary with respect to such security entitlement either:

(i) to identify in its records the Administrative Agent as the entitlement holder of such security entitlement against such securities intermediary or

(ii) to agree in an authenticated record with such Grantor and the Administrative Agent that such securities intermediary will comply with entitlement orders (that is, notifications communicated to such securities intermediary directing transfer or redemption of the financial asset to which such Grantor has a security entitlement) originated by the Administrative Agent without further consent of such Grantor, such authenticated record to be in substantially the form of Exhibit C hereto (in the case of a combined Deposit Account and Securities Account) or Exhibit D hereto (in any other case) or otherwise in form and substance satisfactory to the Administrative Agent (such agreements together being the “Securities Account Control Agreements”).

(d) Subject to Section 4(i) below, no Grantor will add any securities intermediary that maintains a Securities Account for such Grantor or open any new securities account with any then-existing securities intermediary unless:

(i) the Administrative Agent shall have received at least 10 days’ prior written notice of such securities intermediary or such new securities account, and

(ii) the Administrative Agent shall have received, in the case of a securities intermediary that is not the Administrative Agent, a Securities Account Control Agreement authenticated by such new securities intermediary and such Grantor, or a

supplement to an existing Securities Account Control Agreement with such then-existing securities intermediary, covering such new securities account.

No Grantor shall terminate any securities intermediary or terminate any Securities Account, except that a Grantor may terminate a Securities Account, and terminate a securities intermediary with respect to such Securities Account if it gives the Administrative Agent at least 10 days’ prior written notice of such termination (and, upon such termination, Schedule V hereto shall be automatically amended to delete such securities intermediary and Securities Account).

(i) transfer all property held in such terminated Securities Account to another Securities Account, and

(i) comply with instructions originated by the Administrative Agent directing the disposition of funds in the Account Collateral without the further consent of the Grantor and

(ii) waive or subordinate in favor of the Administrative Agent all claims of the Pledged Account Banks (including claims by way of a security interest, lien or right of setoff or right of recoupment) to the Account Collateral, which authenticated record shall be substantially in the form of Exhibit C hereto (in the case of a combined Deposit Account and Securities Account) or of Exhibit B hereto (in any other case), or shall otherwise be in form and substance reasonably satisfactory to, and as negotiated in good faith by, the Administrative Agent (such agreements together being the “Account Control Agreements”), provided that each Grantor shall have up to 30 days following the date hereof to provide any such Account Control Agreement.

(b) Each Grantor will promptly instruct each Person obligated at any time to make any payment to such Grantor for any reason (an “Obligor”) to make such payment to a Deposit Account.

(i) the Administrative Agent shall have received at least 10 days’ prior written notice of such additional bank or such new deposit account, and

(ii) the Administrative Agent shall have received, in the case of a bank or Pledged Account Bank that is not the Administrative Agent, an Account Control Agreement authenticated by such new bank and such Grantor, or a supplement to an existing Account Control Agreement with such then existing Pledged Account Bank, covering such new deposit account.

No Grantor shall terminate any bank as a Pledged Account Bank or terminate any Account Collateral, except that a Grantor may terminate a Deposit Account, and terminate a bank as a Pledged Account Bank with respect to such Deposit Account if it gives the Administrative Agent at least 10 days’ prior written notice of such termination.

(i) transfer all funds held in such terminated Deposit Account to another Deposit Account, and

(e) So long as no Event of Default shall have occurred and be continuing, each Grantor shall have sole right to direct the disposition of funds with respect to each of its Deposit Accounts.

(f) The Administrative Agent may, at any time and without notice to, or consent from, a Grantor transfer, or direct the transfer of, funds from the Account Collateral to satisfy the Grantor’s obligations under the Loan Documents and Lender Hedging Contracts if an Event of Default shall have occurred and be continuing.

A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. Each Grantor ratifies its authorization for the Administrative Agent to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

(c) Each Grantor will furnish to the Administrative Agent from time to time statements and schedules further identifying and describing the Collateral of such Grantor and such other reports in connection with such Collateral as the Administrative Agent may reasonably request, all in reasonable detail.

Except for Permitted Liens, no Grantor will become bound by a security agreement authenticated by another Person (determined as provided in Section 9-203(d) of the UCC) without giving the Administrative Agent 30 days’ prior written notice thereof and taking all action required by the Administrative Agent to ensure that the perfection and first priority nature of the Administrative Agent’s security interest in the Collateral will be maintained. .

(b) Except as otherwise provided in this subsection (c), each Grantor will continue to collect, at its own expense, all amounts due or to become due such Grantor under Receivables and Related Contracts. In connection with such collections, such Grantor may take such action as such Grantor may deem necessary or advisable to enforce collection of the Receivables and Related Contracts; provided that the Administrative Agent shall have the right at any time, upon the occurrence and during the continuance of an Event of Default and upon written notice to such Grantor of its intention to do so, to notify the Obligors under any Receivables and Related Contracts of the assignment of such Receivables and Related Contracts to the Administrative Agent and to direct such Obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to the Administrative Agent and, upon such notification and at the expense of such Grantor, to enforce collection of any such Receivables and Related Contracts, to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done, and to otherwise exercise all rights with respect to such Receivables and Related Contracts, including those set forth set forth in Section 9-607 of the UCC.

(b) Subject to Section 9(c) below, should any Grantor obtain an ownership interest in any item of the type set forth in Section 1(f) that is not on the date hereof a part of the Intellectual Property Collateral:

(i) this Agreement shall automatically apply thereto, and

(ii) any such item and, in the case of trademarks, the goodwill symbolized thereby, shall automatically become part of the Intellectual Property Collateral subject to this Agreement.

Each Grantor shall give prompt written notice to the Administrative Agent identifying such items, and such Grantor shall execute and deliver to the Administrative Agent with such written notice, or otherwise authenticate, an Intellectual Property Security Agreement Supplement substantially in the form of Exhibit F hereto or otherwise in form and substance satisfactory to the Administrative Agent covering such items, which supplement shall be recorded with the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other governmental authorities necessary to perfect the security interest hereunder in such items.

(B) to receive the dividends, interest and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 10(a)(ii) shall automatically cease,

and all such rights shall thereupon become vested in the Administrative Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions.

(ii) All dividends, interest and other distributions that are received by any Grantor contrary to the provisions of paragraph (i) of this Section 10(b) shall be received in trust for the benefit of the Administrative Agent, shall be segregated from other funds of such Grantor and shall be forthwith paid over to the Administrative Agent as Security Collateral in the same form as so received (with any necessary indorsement).

Each Grantor irrevocably appoints the Administrative Agent such Grantor’s attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time , upon the occurrence and during the continuance of an Event of Default, in the Administrative Agent’s discretion, to take any action and to execute any instrument that the Administrative Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including, without limitation:

Section 13. Administrative Agent May Perform. If any Grantor fails to perform any agreement contained herein, the Administrative Agent may, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Administrative Agent incurred in connection therewith shall be payable by such Grantor under Section 16.

Section 14. The Administrative Agent’s Duties. (a) The powers conferred on the Administrative Agent hereunder are solely to protect the Secured Parties’ interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it

hereunder, the Administrative Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Administrative Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property.

(b) Anything contained herein to the contrary notwithstanding, the Administrative Agent may from time to time, when the Administrative Agent deems it to be necessary, appoint one or more subagents for the Administrative Agent hereunder with respect to all or any part of the Collateral. If the Administrative Agent so appoints any such subagent with respect to any Collateral:

(i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Grantor hereunder shall be deemed for purposes of this Security Agreement to have been made to such subagent, in addition to the Administrative Agent, for the ratable benefit of the Secured Parties, as security for the Secured Obligations of such Grantor,

(ii) such subagent shall automatically be vested, in addition to the Administrative Agent, with all rights, powers, privileges, interests and remedies of the Administrative Agent hereunder with respect to such Collateral, and

(iii) the term “Administrative Agent,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Administrative Agent with respect to such Collateral, shall include such subagent;

provided that no such subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Administrative Agent.

Section 15. Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Administrative Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a Secured Party upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also may:

(i) require each Grantor to, and each Grantor will at its expense and upon request of the Administrative Agent forthwith, assemble all or part of the Collateral as directed by the Administrative Agent and make it available to the Administrative Agent at a place and time to be designated by the Administrative Agent that is reasonably convenient to both parties;

(ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Administrative Agent may deem commercially reasonable;

(iii) occupy any premises owned or leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; and

(iv) exercise any and all rights and remedies of any of the Grantors under or in connection with the Collateral, or otherwise in respect of the Collateral, including:

(A) any and all rights of such Grantor to demand or otherwise require payment of any amount under, or performance of any provision of, the Receivables, the Related Contracts and the other Collateral,

(B) withdraw, or cause or direct the withdrawal, of all funds with respect to the Account Collateral and

(C) exercise all other rights and remedies with respect to the Receivables, the Related Contracts and the other Collateral, including those set forth in Section 9-607 of the UCC.

To the extent that notice of sale shall be required by law, at least 10 days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) Any cash held by or on behalf of the Administrative Agent and all cash proceeds received by or on behalf of the Administrative Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Administrative Agent, be held by the Administrative Agent as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Administrative Agent pursuant to Section 16) in whole or in part by the Administrative Agent for the ratable benefit of the Secured Parties against, all or any part of the Secured Obligations, in accordance with Section 8.03 of the Credit Agreement.

(c) The Administrative Agent may, without notice to any Grantor, except as required by law and at any time or from time to time, charge, set-off and otherwise apply

all or any part of the Secured Obligations against any funds held with respect to the Account Collateral or in any other deposit account.

(d) In the event of any sale or other disposition of any of the Intellectual Property Collateral of any Grantor, the goodwill symbolized by any trademarks subject to such sale or other disposition shall be included therein, and such Grantor shall supply to the Administrative Agent or its designee such Grantor’s know-how and expertise, and documents and things relating to any Intellectual Property Collateral subject to such sale or other disposition, and such Grantor’s customer lists and other records and documents relating to such Intellectual Property Collateral and to the manufacture, distribution, advertising and sale of products and services of such Grantor.

(e) The Grantors recognize that the Administrative Agent may deem it impracticable to effect a public sale of all or any part of the Security Collateral and that the Administrative Agent may, therefore, determine to make one or more private sales of any such securities to a restricted group of purchasers who will be obligated to agree, among other things, to acquire such securities for their own account, for investment and not with a view to the distribution or resale thereof. The Grantors acknowledge that any such private sale may be at prices and on terms less favorable to the seller than the prices and other terms which might have been obtained at a public sale and, notwithstanding the foregoing, agree that such private sales shall be deemed to have been made in a commercially reasonable manner and that the Administrative Agent shall have no obligation to delay sale of any such securities for the period of time necessary to permit the Issuer of such securities to register such securities for public sale under the Securities Act of 1933, as amended. Any offer to sell such securities that has been:

(i) publicly advertised on a bona fide basis in a newspaper or other publication of general circulation in the financial community of New York, New York (to the extent that such an offer may be so advertised without prior registration under such Securities Act), or

(ii) made privately in the manner described above to not less than 15 bona-fide offerees,

shall be deemed to involve a “public disposition” for the purposes of Section 9.610(c) of the UCC (or any successor or similar, applicable statutory provision), notwithstanding that such sale may not constitute a “public offering” under the Securities Act, and that the Administrative Agent or any other Secured Party may, in such event, bid for the purchase of such securities.

Section 16. Indemnity and Expenses. (a) Each Grantor shall indemnify Administrative Agent (and any sub-agent thereof), each Secured Party and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any

Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by any Grantor arising out of, in connection with, or as a result of:

(i) the execution or delivery of this Agreement, any other Loan Document, any Lender Hedging Contract or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby,

(ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom, or

(iii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by any Grantor, and regardless of whether any Indemnitee is a party thereto.

THE FOREGOING INDEMNIFICATION WILL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY INDEMNITEE, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or if a Grantor has obtained a final and non-appealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

(b) Each Grantor will upon demand pay to the Administrative Agent the amount of any and all reasonable expenses, including the reasonable fees and expenses of its counsel and of any experts and agents, that the Administrative Agent may incur in connection with:

(i) the administration of this Agreement,

(ii) the custody, preservation, use or operation of, or the sale of, collection from or other realization upon, any of the Collateral of such Grantor,

(iii) the exercise or enforcement of any of the rights of the Administrative Agent or the other Secured Parties hereunder or

(iv) the failure by such Grantor to perform or observe any of the provisions hereof.

(c) To the fullest extent permitted by applicable law, no Grantor shall 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, any Lender Hedging Contract or any agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in subsection (a) shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement, the other Loan Documents, the Lender Hedging Contracts or the transactions contemplated hereby or thereby.

Section 17. Subordination of Liens. Each Grantor confirms that: any and all Liens securing debts, liabilities and other Obligations owed to such Grantor by any other Loan Party (“Subordinated Liens”) shall be subordinate to any and all Liens under the Security Documents securing the Secured Obligations (“Senior Liens”) as if the Senior Liens were created, filed, recorded and otherwise perfected prior in time to the creation, filing, recording and other perfection of the Subordinated Liens, and

(b) by reason of this Agreement, the Administrative Agent, for the benefit of the Secured Parties, has a perfected, first-priority Lien on each Subordinated Lien and the right, to the exclusion of any Grantor, to enforce, exercise remedies, grant waivers, release and take any and all other actions with respect to such Subordinated Lien.

Section 18. Amendments; Waivers; Additional Grantors; Etc. (a) No amendment or waiver of any provision of this Agreement, and no consent to any departure by any Grantor herefrom shall in any event be effective unless the same shall be entered into in accordance with Section 10.01 of the Credit Agreement. No failure on the part of the Administrative Agent or any other Secured Party to exercise, and no delay in exercising any right hereunder, 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.

(b) Upon the execution and delivery, or authentication, by any Person of a security agreement supplement in substantially the form of Exhibit A hereto (each a “Security Agreement Supplement”):

(i) such Person shall be referred to as an “Additional Grantor” and shall be and become a Grantor hereunder, and each reference in this Agreement and the other Loan Documents to “Grantor” shall also mean and be a reference to such Additional Grantor, and each reference in this Agreement, the other Loan Documents and the Lender Hedging Contracts to “Collateral” shall also mean and be a reference to the Collateral of such Additional Grantor, and

(ii) the supplemental schedules attached to each Security Agreement Supplement shall be incorporated into and become a part of and supplement the respective Schedule hereto, and the Administrative Agent may attach such supplemental schedules to such Schedules; and each reference to such Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Security Agreement Supplement.

Section 19. Notices, Etc. All notices and other communications provided for hereunder shall be delivered in the manner provided in the Credit Agreement, in the case of the Borrower or the Administrative Agent, addressed to it at its address specified in the Credit Agreement and, in the case of each Grantor other than the Borrower, addressed to it at its address set forth opposite such Grantor’s name on the signature pages hereto or on the signature page to the Security Agreement Supplement pursuant to which it became a party hereto; or, as to any party, at such other address as shall be designated by such party in a written notice to the other parties. All such notices and other communications shall be effective when and as provided in the Credit Agreement. Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or of any Security Agreement Supplement or Schedule hereto shall be effective as delivery of an original executed counterpart thereof.

(a) remain in full force and effect until the latest of:
