2.02 Borrowings, Conversions and Continuations of Revolving Credit Loans.

(a) Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Eurodollar Rate Loans shall be made upon Borrower’s irrevocable notice to Administrative Agent, which may be given by telephone. Each such notice must be received by Administrative Agent not later than 11:00 a.m. (i) three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base Rate Loans, and (ii) on the Business Day prior to the requested date of any Borrowing of Base Rate Loans. Not later than 11:00 a.m., three Business Days before the requested date of such Borrowing, conversion or continuation, as to Eurodollar Rate Loans, Administrative Agent shall notify Borrower (which notice may be by telephone) whether or not the requested Interest Period has been consented to by all Lenders. Each telephonic notice by Borrower pursuant to this Section 2.02(a) must be confirmed promptly by delivery to Administrative Agent of a written Loan Notice, appropriately completed and signed by a Responsible Officer of Borrower. Each Borrowing of, conversion to or continuation 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. Except as provided in Section 2.03(c) and any Borrowing of the then existing full availability under the Agreement, each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof.

converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

(b) Following receipt of a Loan Notice, Administrative Agent shall promptly notify each Lender of the amount of its Applicable Revolving Credit Percentage of the applicable Revolving Credit Loans, and if no timely notice of a conversion or continuation is provided by Borrower, Administrative Agent shall notify each Lender of the details of any automatic conversion to Base Rate Loans described in the preceding subsection. In the case of a Borrowing, each Lender shall make the amount of its Loan available to Administrative Agent in immediately available funds at Administrative Agent’s Office not later than 1:00 p.m. on the Business Day specified in the applicable Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01), Administrative Agent shall make all funds so received available to Borrower in like funds as received by Administrative Agent either by (i) crediting the account of Borrower on the books of Bank of America with the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) Administrative Agent by Borrower; provided, however, that if, on the date the Loan Notice with respect to a Borrowing is given by Borrower, there are L/C Borrowings outstanding, then the proceeds of such Borrowing first, shall be applied, to the payment in full of any such L/C Borrowings, and second, shall be made available to Borrower as provided above.

(c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of an Interest Period for such Eurodollar Rate Loan. During the existence of an Event of Default, no Loans may be requested as, converted to or continued as Eurodollar Rate Loans without the consent of the Required Lenders, and the Required Lenders may demand that any or all of the then outstanding Eurodollar Rate Loans be converted immediately to Base Rate Loans and Borrower agrees to pay all amounts due under Section 3.05 in accordance with the terms thereof due to any such conversion.

(d) Administrative Agent shall promptly notify Borrower and Lenders of the interest rate applicable to any Interest Period for Eurodollar Rate Loans upon determination of such interest rate. At any time that Base Rate Loans are outstanding, Administrative Agent shall notify Borrower and the Lenders of any change in Bank of America’s prime rate used in determining the Base Rate promptly following the public announcement of such change.

(e) After giving effect to all Borrowings, all conversions of Revolving Credit Loans from one Type to the other, and all continuations of Revolving Credit Loans as the same Type, there shall not be more than ten Interest Periods in effect with respect to Revolving Credit Loans.

Such L/C Application must be received by the L/C Issuer and Administrative Agent not later than 11:00 a.m. at least two Business Days (or such later date and time as Administrative Agent and the L/C Issuer may agree in a particular instance in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be.

Unless the L/C Issuer has received written notice from any Lender, 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 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 Borrower (or the applicable Subsidiary) 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.

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 L/C 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 five Business Days before the Non-Extension Notice Date (1) from Administrative Agent that the Required Lenders have elected not to permit such extension or (2) from Administrative Agent, any Lender or 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.

(v) If 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, 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 Administrative Agent that the Required Lenders have elected not to permit such reinstatement or (B) from Administrative Agent, any Lender or 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.

(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 Borrower and 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”), Borrower shall reimburse the L/C Issuer through Administrative Agent in an amount equal to the amount of such drawing. If Borrower fails to so reimburse the L/C Issuer by such time, 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 Revolving Credit Percentage thereof. In such event, Borrower shall be deemed to have requested a 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 Revolving Credit Commitments and the conditions set forth in Section 4.02 (other than the delivery of a Loan Notice). Any notice given by the L/C Issuer or 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 Administrative Agent for the account of the L/C Issuer at Administrative Agent’s Office in an amount equal to its Applicable Revolving Credit Percentage of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by 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 Loan to Borrower in such amount. 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 Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, 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 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 Revolving Credit 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 Revolving Credit Percentage of such amount shall be solely for the account of the L/C Issuer.

(v) Each Lender’s obligation to make Revolving Credit 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, 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 Revolving Credit Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other than delivery by Borrower of a Loan Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation of 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 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 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 LC/ 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 Revolving Credit Loan included in the relevant 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 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 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 Borrower or otherwise, including proceeds of Cash Collateral applied thereto by Administrative Agent), Administrative Agent will distribute to such Lender its Applicable Revolving Credit Percentage thereof in the same funds as those received by Administrative Agent.

(ii) If any payment received by 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 Administrative Agent for the account of the L/C Issuer its Applicable Revolving Credit Percentage thereof on demand of 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 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 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 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, Borrower or any of its Subsidiaries.

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 Borrower’s instructions or other irregularity, Borrower will immediately notify the L/C Issuer. 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 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, 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 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. 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 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, 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, Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be liable to Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by Borrower which 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 Administrative Agent, (i) if an Event of Default has occurred and is continuing, or (ii) if, as of the L/C Expiration Date, any L/C Obligation for any reason remains outstanding, Borrower shall, in each case, immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations. Sections 2.05 and 8.02(a)(iii) set forth certain additional requirements to deliver Cash Collateral hereunder. For purposes hereof, “Cash Collateralize” means to pledge and deposit with or deliver to Collateral 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 Administrative Agent and the L/C Issuer (which documents are hereby consented to by Lenders). Derivatives of such term have corresponding meanings. Borrower hereby grants to Collateral Agent, for the benefit of the L/C Issuer and 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. If at any time Administrative Agent determines that any funds held as Cash Collateral are subject to any right or claim of any Person other than Collateral Agent or that the total amount of such funds is less than the aggregate Outstanding Amount of all L/C Obligations, Borrower will, forthwith upon demand by Administrative Agent, pay to Collateral Agent, as additional funds to be deposited as Cash Collateral, an amount equal to the excess of (x) such aggregate Outstanding Amount over (y) the total amount of funds, if any, then held as Cash Collateral that Administrative Agent determines to be free and clear of any such right and claim. Upon the drawing of any Letter of Credit for which funds are on deposit as Cash Collateral, such funds shall be applied, to the extent permitted under applicable Laws, to reimburse the L/C Issuer.

(h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the L/C Issuer and 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 (the “ICC”) at the time of issuance shall apply to each commercial Letter of Credit.

(i) L/C Fees. Borrower shall pay to Administrative Agent for the account of each Lender in accordance with its Applicable Revolving Credit Percentage a L/C fee (the “L/C 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 1.06. L/C 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 L/C 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 L/C Fees shall accrue at the Default Rate.

(j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. 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 per annum specified in Administrative Agent Fee Letter, computed on the daily amount available to be drawn under such Letter of Credit and on a quarterly basis in arrears. Such fronting fee shall be due and payable on the tenth 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 L/C 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 1.06. In addition, 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 individual 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 Documents, the terms hereof shall control.

(l) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary, Borrower shall be obligated to reimburse the L/C Issuer hereunder for any and all drawings under such Letter of Credit. Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of Borrower, and that Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

2.04 Voluntary Prepayments. Borrower may, upon notice to Administrative Agent, at any time or from time to time voluntarily prepay Revolving Credit Loans in whole or in part without premium or penalty except as provided in Section 2.04(b); provided that (i) such notice must be received by 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) one Business Day prior to any prepayment of Base Rate 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 Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 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 Loans to be prepaid and if Eurodollar Rate Loans are to be prepaid, the Interest Period(s) of such Loans. Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s ratable portion of such prepayment (based upon such Lender’s Applicable Revolving Credit Percentage). If such notice is given by

Borrower, 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 of Revolving Credit Loans pursuant to this Section 2.04 shall be applied to the Revolving Credit Loans of Lenders in accordance with their respective Applicable Revolving Credit Percentages.

2.05 Required Prepayments.

(a) Except in the circumstances provided in Section 2.05(b), (c), (d) or (e) if at any time the Total Revolving Credit Outstandings exceed the Borrowing Base on such date plus, during the Overadvance Period, the Overadvance Amount on such date (such excess being herein called a “Borrowing Base Deficiency”), Borrower shall, within ten days after Administrative Agent gives notice of such fact to Borrower, give notice to Administrative Agent that it has elected will do one or a combination of the following sufficient to eliminate such Borrowing Base Deficiency:

(i) prepay the principal of the Revolving Credit Loans (and after all Revolving Credit Loans are repaid in full, Cash Collateralize the L/C Obligations in accordance with Section 2.03(g)) within ten days after such notice by Borrower in an aggregate amount at least equal to such Borrowing Base Deficiency;

(ii) prepay the principal of the Revolving Credit Loans (and, after all Revolving Credit Loans are repaid in full, Cash Collateral the L/C Obligations in accordance with Section 2.03(g)) in monthly installments approved by Administrative Agent, but in no event to exceed six installments without the approval of Required Lenders, in an aggregate amount at least equal to such Borrowing Base Deficiency, with the first such installment to be paid within thirty days after the giving of such notice by Borrower and the subsequent installments to be due and payable at one month intervals thereafter until such Borrowing Base Deficiency has been eliminated; or

(iii) submit to Administrative Agent with such notice, information regarding additional assets owned by Borrower or its Subsidiaries that were not previously considered in the determination of the Borrowing Base and within thirty days after such notice by Borrower provide to Administrative Agent deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other security documents granting, confirming, and perfecting first and prior liens or security interests in such assets, in each case satisfactory to Administrative Agent in its sole discretion, the value of which shall be sufficient in the determination of Administrative Agent, in its sole discretion, to increase the Borrowing Base to an amount which eliminates such Borrowing Base Deficiency; whereupon Borrower shall be obligated to provide such security documents within such thirty days after such notice by Borrower;

provided, however, to the extent that the installments under subsection (ii) of this Section 2.05(a) are not approved by Administrative Agent or Borrower is unable

to demonstrate to the satisfaction of Administrative Agent within ten days after the date of any such election under subsection (ii) of this Section 2.05(a) that Borrower has sufficient available monthly cash from Projected Oil and Gas Production to pay such installments or to the extent Administrative Agent determines that such assets and security documents to be provided under subsection (iii) of this Section 2.05(a) will not be satisfactory or will not increase the Borrowing Base to an amount which eliminates such Borrowing Base Deficiency, then, within ten days after receiving notice of such determination from Administrative Agent, Borrower will make the prepayment specified in subsection (i) of this Section 2.05(a).

(b) During the Overadvance Period,

(i) on the date of the consummation of any Announced Divestiture, the incurrence or issuance by Borrower or any of its Subsidiaries of any Indebtedness (other than Indebtedness expressly permitted to be incurred or issued pursuant to Section 7.03) or the consummation of an Equity Issuance, the Overadvance Amount shall be reduced to zero; and

(ii) on the date of consummation of any Subject Disposition (other than an Announced Divestiture), the Overadvance Amount shall be reduced by an amount equal to the Net Cash Proceeds attributable to such Disposition, minus the Borrowing Base value of the Oil and Gas Properties which are subject to such Disposition (which shall be the Borrowing Base value assigned thereto as determined by Administrative Agent, and which, in the case of any exchange, shall be the net reduction in the Borrowing Base value realized or resulting from such exchange).

On the last day of the Overadvance Period to the extent the Total Revolving Credit Outstandings exceed the Borrowing Base as a result of the elimination of the Overadvance Amount, the Borrower shall make a mandatory prepayment of the Revolving Credit Loans (and after all Revolving Credit Loans are repaid in full, Cash Collateralize the L/C Obligations in accordance with Section 2.03(g)) in the amount of such excess.

(c) On the date of the consummation of any Subject Disposition, if the Total Revolving Credit Outstandings exceed or would exceed the Borrowing Base (including as a result of the elimination or reduction of the Overadvance Amount pursuant to Section 2.05(b) and the reduction of the Borrowing Base pursuant to Section 2.15(d)) (for the avoidance of doubt, it is not intended that the Borrowing Base shall be redetermined solely by virtue of the occurrence of an Announced Divestiture), the Borrower shall make a mandatory prepayment of the Revolving Credit Loans (and after all Revolving Credit Loans are repaid in full, Cash Collateralize the L/C Obligations in accordance with Section 2.03(g)) in amount of such excess.

(d) Upon the incurrence or issuance by Borrower or any of its Subsidiaries of any Indebtedness (other than Indebtedness expressly permitted to be incurred or issued

pursuant to Section 7.03), if the Total Revolving Credit Outstandings exceed or would exceed the Borrowing Base (including as a result of the elimination of the Overadvance Amount pursuant to Section 2.05(b)), the Borrower shall make a mandatory prepayment of the Revolving Credit Loans (and after all Revolving Credit Loans are repaid in full, Cash Collateralize the L/C Obligations in accordance with Section 2.03(g)) in amount of such excess.

(e) On the date of the consummation of an Equity Issuance, if the Total Revolving Credit Outstandings exceed or would exceed the Borrowing Base (including as a result of the elimination of the Overadvance Amount pursuant to Section 2.05(b)), the Borrower shall make a mandatory prepayment of the Revolving Credit Loans (and after all Revolving Credit Loans are repaid in full, Cash Collateralize the L/C Obligations in accordance with Section 2.03(g)) in amount of such excess.

2.06 Reduction of Revolving Credit Commitments. Borrower may, upon notice to Administrative Agent, terminate the Aggregate Revolving Credit Commitments, or from time to time permanently reduce the Aggregate Revolving Credit Commitments; provided that (i) any such notice shall be received by Administrative Agent not later than 11:00 a.m. three Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) Borrower shall not terminate or reduce the Aggregate Revolving Credit Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Revolving Credit Outstandings would exceed the Aggregate Revolving Credit Commitments, and (iv) if, after giving effect to any reduction of the Aggregate Revolving Credit Commitments or the L/C Sublimit exceeds the amount of the Aggregate Revolving Credit Commitments, such Sublimit shall be automatically reduced by the amount of such excess. If following any such reduction or termination, the Borrowing Base exceeds the Aggregate Revolving Credit Commitments, the Borrowing Base shall be reduced to the amount of the Aggregate Revolving Credit Commitments automatically without further action by any Person. Administrative Agent will promptly notify the Lenders of any such notice of termination or reduction of the Aggregate Revolving Credit Commitments. Any reduction of the Aggregate Revolving Credit Commitments shall be applied to the Revolving Credit Commitment of each Lender according to its Applicable Revolving Credit Percentage. All fees accrued until the effective date of any termination of the Aggregate Revolving Credit Commitments shall be paid on the effective date of such termination.

2.07 Repayment of Loans. Borrower shall repay to Lenders on the Maturity Date for Revolving Credit Loans the aggregate principal amount of Revolving Credit Loans outstanding on such date.

2.08 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; and (ii) each Base Rate 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 (after taking into account any applicable grace periods) and an Event of Default results therefrom, 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 Borrower under any Loan Document is not paid when due (after taking into account any applicable grace periods) and an Event of Default results therefrom, 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, 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.

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

(a) Unused Fee. Borrower shall pay to Administrative Agent for the account of each Lender in accordance with its Applicable Revolving Credit Percentage, an unused fee (the “Unused Fee”) equal to the Applicable Rate times the Unused Availability. The unused 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 Unused 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.

(b) Administrative Agent’s Fees. Borrower shall pay to Administrative Agent for Administrative Agent’s own account, fees in the amounts and at the times specified in the letter agreement, dated March 13, 2007 (the “Administrative Agent Fee Letter”), between Borrower

and Administrative Agent. Such fees shall be fully earned when paid and shall be nonrefundable for any reason whatsoever.

2.10 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 2.12(a), bear interest for one day. Each determination by Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

2.11 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 Administrative Agent in the ordinary course of business. The accounts or records maintained by Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Credit Extensions made by Lenders to 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 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 Administrative Agent in respect of such matters, the accounts and records of Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through Administrative Agent, Borrower shall execute and deliver to such Lender (through 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 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. In the event of any conflict between the accounts and records maintained by Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of Administrative Agent shall control in the absence of manifest error.

2.12 Payments Generally; Administrative Agent’s Clawback.

(a) General. All payments to be made by Borrower shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by Borrower hereunder shall be made to Administrative Agent, for the account of the respective Lenders to which such payment

is owed, at Administrative Agent’s Office in Dollars and in immediately available funds not later than 12:00 noon on the date specified herein. Administrative Agent will promptly distribute to each Lender its Applicable Revolving Credit 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 Administrative Agent after 12:00 noon 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 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 Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurodollar Rate Loans (or, in the case of any Borrowing of Base Rate Loans, prior to 12:00 noon on the date of such Borrowing) that such Lender will not make available to Administrative Agent such Lender’s share of such Borrowing, 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 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 Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to Administrative Agent, then the applicable Lender and Borrower severally agree to pay to 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 Borrower to but excluding the date of payment to 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 Administrative Agent in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by Administrative Agent in connection with the foregoing and (B) in the case of a payment to be made by Borrower, the interest rate applicable to Base Rate Loans. If Borrower and such Lender shall pay such interest to Administrative Agent for the same or an overlapping period, Administrative Agent shall promptly remit to Borrower the amount of such interest paid by Borrower for such period. If such Lender pays its share of the applicable Borrowing to Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any payment by Borrower shall be without prejudice to any claim Borrower may have against a Lender that shall have failed to make such payment to Administrative Agent.

(ii) Payments by Borrower; Presumptions by Administrative Agent. Unless Administrative Agent shall have received notice from Borrower prior to the time at which any payment is due to Administrative Agent for the account of the Lenders or the L/C Issuer hereunder that Borrower will not make such payment, Administrative Agent may assume that 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 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 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 Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by Administrative Agent in accordance with banking industry rules on interbank compensation. A notice of Administrative Agent to any Lender or 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 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 Borrower by 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, 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 Lenders hereunder to make Revolving Credit Loans, to fund participations in Letters of Credit and to make payments under Section 10.04(c) are several and not joint. The failure of any Lender to make any 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 Loan, 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.

(f) Insufficient Funds. If at any time insufficient funds are received by and available to Administrative Agent to pay fully all amounts of principal, L/C Borrowings, interest and fees then due hereunder, such funds shall be applied (i) first, toward payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, toward payment of principal and L/C Borrowings then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and L/C Borrowings then due to such parties.

2.13 Sharing of Payments. (a) 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 Loans made by it, or the participations in L/C Obligations held by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such 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 Loans and subparticipations in L/C Obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Committed Loans and other amounts owing them.

(b) Notwithstanding the foregoing:

(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 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 Loans or subparticipations in L/C Obligations to any assignee or participant, other than to Borrower or any Subsidiary thereof (as to which the provisions of this Section shall apply).

(c) Each Loan Party 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 such Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of such participation.

2.14 Initial Borrowing Base. The initial Borrowing Base shall be $200,000,000.

2.15 Subsequent Determinations of Borrowing Base.

(a) By April 1 and October 1 of each year, beginning October 1, 2007, Borrower shall furnish to each Lender all information, reports and data which Administrative Agent has then requested concerning Loan Parties’ businesses and properties (including their oil and gas properties and interests and the reserves and production relating thereto), together with, as applicable, the Engineering Report as of January 1 described in Section 6.02(d) or as of July 1 described in Section 6.02(e). Within thirty calendar days after receiving such information, reports and data, or as promptly thereafter as practicable, Administrative Agent shall, in good faith, determine the amount of a proposed Borrowing Base. Administrative Agent shall then deliver to each Lender such proposed Borrowing Base. Within fifteen calendar days after the Lenders’ receipt thereof, or as promptly thereafter as practicable, Supermajority Lenders shall, in good faith, agree upon an amount for the Borrowing Base (provided that all Lenders must agree upon any increase in the Borrowing Base), which need not be equal to such proposed Borrowing Base. If Borrower has specified to Administrative Agent a maximum Borrowing Base requested by Borrower at the time of its delivery of information, reports and data contemplated by this Section, Administrative Agent shall notify the Lenders of such request, and the Borrowing Base determined by Supermajority

Lenders (or all Lenders, as applicable) shall not exceed such requested amount. Such determinations by Administrative Agent or any Lenders constituting Supermajority Lenders (or all Lenders, as applicable) shall determine the amount of the Borrowing Base based upon the loan collateral value which they in their sole discretion assign to the discounted net present value of the various oil and gas properties included in the Collateral of Loan Parties at the time in question and based upon such other credit factors (including without limitation the assets, liabilities, cash flow, hedged and unhedged exposure to price, foreign exchange rate, and interest rate changes, business, properties, prospects, management and ownership of Loan Parties and their Affiliates) as they in their sole discretion deem significant in accordance with their respective normal and customary lending practices. If Supermajority Lenders (or all Lenders in the case of an increase in the Borrowing Base) have not approved the Borrowing Base within the fifteen calendar day period after their receipt of such proposed Borrowing Base, Administrative Agent shall poll Lenders to ascertain the highest Borrowing Base then acceptable to a number of Lenders sufficient to constitute Supermajority Lenders (or all Lenders in the case of an increase in the Borrowing Base) and such amount shall then become the Borrowing Base. Administrative Agent shall by notice to Borrower designate such amount as the new Borrowing Base available to Borrower hereunder, which designation shall take effect immediately on the date such notice is sent (herein called a “Determination Date”) and shall remain in effect until but not including the next date as of which the Borrowing Base is redetermined (each a “Borrowing Base Period”). IT IS EXPRESSLY UNDERSTOOD THAT, SUBJECT TO THE FOREGOING PROVISIONS OF THIS SECTION, LENDERS AND ADMINISTRATIVE AGENT HAVE NO OBLIGATION TO AGREE UPON OR DESIGNATE THE BORROWING BASE AT ANY PARTICULAR AMOUNT, WHETHER IN RELATION TO THE MAXIMUM LOAN AMOUNT OR OTHERWISE, AND THAT LENDERS’ COMMITMENTS TO ADVANCE FUNDS HEREUNDER IS DETERMINED BY REFERENCE TO THE BORROWING BASE FROM TIME TO TIME IN EFFECT, WHICH BORROWING BASE SHALL BE USED FOR CALCULATING UNUSED FEES UNDER SECTION 2.09 AND, TO THE EXTENT PERMITTED BY LAW AND REGULATORY AUTHORITIES, FOR THE PURPOSES OF CAPITAL ADEQUACY DETERMINATION AND REIMBURSEMENTS UNDER SECTION 3.04.

(b) If Borrower does not furnish all such information, reports and data by the date specified in the first sentence of subsection (a) of this section, Administrative Agent may nonetheless designate the Borrowing Base at any amount that Supermajority Lenders determine and may redesignate the Borrowing Base from time to time thereafter (provided that all Lenders must agree to any increase in the Borrowing Base) until each Lender receives all such information, reports and data, whereupon Supermajority Lenders (or all Lenders, as applicable) shall designate a new Borrowing Base as described above.

(c) In addition to the redeterminations of the Borrowing Base pursuant to subsections (a) and (b) of this section, Borrower and Administrative Agent (or Administrative Agent at the request of Required Lenders) may each request additional determinations (“Special Determinations”) of the Borrowing Base from time to time; provided, that Borrower may request no more than one Special Determinations in any calendar year and Administrative Agent (or Administrative Agent at the Request of Required Lenders) may request no more than one Special Determinations in any calendar year thereafter. In the event Administrative Agent (or Administrative Agent at the

request of Required Lenders) requests such a Special Determination, Administrative Agent shall promptly deliver notice of such request to Borrower and Borrower shall, within thirty (30) calendar days following the date of such request, deliver to Lenders an Engineering Report prepared by petroleum engineers who are employees of Borrower as of the last day of the calendar month preceding the date of such request and such other information which Administrative Agent shall have requested. In the event Borrower requests a Special Determination, Borrower shall deliver written notice of such request to Lenders which shall include (i) an Engineering Report prepared as of a date not more than thirty (30) days prior to the date of such request (or, in the case of a request made on the 31^st day of any calendar month, thirty-one (31) days), (ii) the amount of the Borrowing Base requested by Borrower and to become effective on the Determination Date applicable to such Special Determination and (iii) such other information which Administrative Agent shall have reasonably requested. Upon receipt of such Engineering Report and other information, Administrative Agent shall, subject to approval of Supermajority Lenders, or all Lenders in the event of a proposed increase in the Borrowing Base, redetermine the Borrowing Base in accordance with the procedure set forth in subsection (a) of this section, which Borrowing Base shall become effective on the Determination Date (or as soon thereafter as Administrative Agent and Supermajority Lenders, or all Lenders in the event of a proposed increase in the Borrowing Base, approve such Borrowing Base and provide notice thereof to Borrower).

(d) In addition to Scheduled Determinations and Special Determinations, the Borrowing Base shall automatically reduce, simultaneously with the completion by any Loan Party of any Subject Disposition (other than an Announced Divestiture) resulting in Net Cash Proceeds in excess of $10,000,000.

(e) either individually or in the aggregate since the date of the then most recent Scheduled Determination), by the Borrowing Base value of the Oil and Gas Properties which are subject to such Disposition (which shall be the Borrowing Base value assigned thereto as determined by Administrative Agent, and which, in the case of any exchange, shall be the net reduction in the Borrowing Base value realized or resulting from such exchange).

ARTICLE III. TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Payments Free of Taxes. Any and all payments by Borrower to or on account of any obligation of 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 Borrower shall be required by any applicable law to deduct any Indemnified Taxes (or Other Taxes) from such payments, then, (i) the sum payable shall be increased as necessary so that after making all required deductions of such indemnified Taxes or Other Taxes (including deductions applicable to additional sums payable under this Section), Administrative Agent, Lender or the 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) Borrower shall make such deductions, and (iii) Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Indemnification by Borrower. Borrower shall indemnify 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 Administrative Agent, such Lender or the L/C Issuer, as the case may be, and any 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 provided that Administrative Agent, any Lender or the L/C Issuer shall not be entitled to received any indemnification with respect to Indemnified Taxes or Other Taxes that are incurred or accrued more than nine (9) months prior to the date such party gives notice and demand with respect thereto to Borrower (except if such incurrence or accrual is retroactively effective, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof) or where the liability to pay such Indemnified Tax or Other Tax has been incurred as a result of the gross negligence, bad faith or willful misconduct of Administrative Agent, any Lender, or the L/C Issuer (or their respective Affiliates, Agents or employees). A certificate as to the amount of such payment or liability delivered to Borrower by a Lender or the L/C Issuer (with a copy to Administrative Agent), or by Administrative Agent on its own behalf or on behalf of a Lender or the L/C Issuer, along with a reasonable detailed explanation of such liability, shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by Borrower to a Governmental Authority, Borrower shall deliver to 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 Administrative Agent.

(e) Status of Lenders. Any Lender, if requested by Borrower or Administrative Agent, shall deliver such documentation prescribed by applicable law or reasonably requested by Borrower or Administrative Agent as will enable Borrower or Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax or any Indemnified Taxes or Other Taxes under the law of the jurisdiction in which 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 Borrower (with a copy to Administrative Agent), at the time or times reasonably requested by Borrower or Administrative Agent,

such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or reduction of withholding. In addition, any Lender, if requested by Borrower or Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by Borrower or Administrative Agent as will enable Borrower or 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, if Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to Borrower and 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 Borrower or 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, (A) a certificate to the effect that such Foreign Lender is not (1) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (2) a “10 percent shareholder” of Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (3) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (B) duly completed copies of Internal Revenue Service Form W-8BEN (or any successor form), 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 Borrower to determine the withholding or deduction required to be made.

(f) Status of U.S. Lenders. Without limiting the generality of Section 3.01(e), each Lender that is not a Foreign Lender (except for any Lender that is presumed to be a corporation pursuant to exempt indicators under Section 1.6049-4(c)(1)(ii)(A)(1) of the Treasury Regulations or any successor provision) shall deliver to Borrower and the Administrative Agent (in such number of copies as shall be reasonably requested by the recipient) on or prior to the date that such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Borrower or the Administrative Agent), duly completed copies of IRS Form W-9 (or any successor or substitute form) confirming an exemption from U.S. federal backup withholding.

(g) Treatment of Certain Refunds. If Administrative Agent, any Lender or the L/C Issuer determines, in its sole discretion, that it has received a refund of any

Indemnified Taxes or Other Taxes as to which it has been indemnified by Borrower or with respect to which Borrower has paid additional amounts pursuant to this Section, it shall pay to Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by 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 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 Borrower, upon the request of Administrative Agent, such Lender or the L/C Issuer, agrees to repay the amount paid over to Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to Administrative Agent, such Lender or the L/C Issuer in the event 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 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 reasonably deems confidential) to Borrower or any other Person.

(h) If Borrower determines that a reasonable basis exists for contesting an Indemnified Tax or Other Tax, each Lender, the L/C Issuer or Administrative Agent, as the case may be, shall use reasonable efforts (at Borrower’s expense) to cooperate with Borrower as Borrower may reasonably request in challenging such Indemnified Tax or Other Tax. Each Lender, the L/C Issuer and Administrative Agent agree to use reasonable efforts to cooperate with Borrower as Borrower may reasonably request (at Borrower’s expense) to minimize any amount payable by Borrower pursuant to this Section 3.01(h).

3.02 Illegality. If any Lender reasonably 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 Borrower through Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies Administrative Agent and Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, Borrower shall, upon demand from such Lender (with a copy to 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, Borrower shall also pay accrued interest on the amount so prepaid or converted and all amounts due under Section 3.05 in accordance with the terms thereof due to such prepayment or conversion.

3.03 Inability to Determine Rates. If Administrative Agent reasonably determines 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 Base Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan, or (c) the Eurodollar Base 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 Eurodollar Rate Loan, Administrative Agent will promptly so notify Borrower and each Lender. Thereafter, the obligation of Lenders to make or maintain Eurodollar Rate Loans shall be suspended until Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, 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.

(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 reflected in the Eurodollar Rate) or the L/C Issuer; or

(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 the imposition of, or any change in the rate of, any Indemnified Taxes or Other Taxes (which shall be covered exclusively by Section 3.01) or the imposition of, or any change in the rate of, any Excluded Taxes); 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, 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 Revolving Credit Commitment 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 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 Borrower shall be conclusive absent manifest error. 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 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 nine months prior to the date that such Lender or the L/C Issuer, as the case may be, notifies 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. 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 Borrower shall have received at least 10 days’ prior notice (with a copy to 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 Administrative Agent) from time to time, 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 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 Borrower;

(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 (i) any syndication activity in connection with the Revolving Credit Facility within 90 days after the Closing Date or (ii) a request by Borrower pursuant to Section 10.13;

including any loss of anticipated profits and 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. Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing. For purposes of calculating amounts payable by Borrower to Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Base Rate used in determining the Eurodollar Rate for such Eurodollar Rate 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.

After giving full effect to the Permitted Liens, Borrower or the Subsidiary specified as the owner owns the net interests in production attributable to the Oil and Gas Properties as reflected in the most recently delivered Engineering Report, and the ownership of such Properties shall not in any material respect obligate Borrower or such Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Engineering Report that is not offset by a corresponding proportionate increase in Borrower’s or such Subsidiary’s net revenue interest in such Property.

(b) All material leases and agreements necessary for the conduct of the business of Borrower and its Subsidiaries are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would affect in any material respect the conduct of the business of Borrower and its Subsidiaries, taken as a whole.

(c) The leases which constitute any part of the Oil and Gas Properties are in full force and effect as to those portions within such Oil and Gas Properties, are valid, subsisting leases as to those portions within such Oil and Gas Properties to which they pertain and all rentals, royalties, overriding royalties, net profits or other production burdens and other amounts due and payable in accordance with the terms of the leases as to those portions within such Oil and Gas Properties have been duly paid or provided for; the obligations to be performed under the leases as to those portions within such Oil and Gas Properties have been duly performed; and Borrower is not aware of any default by any third party under any of the leases with respect to such third party’s obligations.

(d) The rights and Properties presently owned, leased or licensed by Borrower and its Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit Borrower and its Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the date hereof.

Borrower and its Subsidiaries either own or have valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a Material Adverse Effect.

Except for such acts or failures to act as could not be reasonably expected to have a Material Adverse Effect, the Oil and Gas Properties of Borrower and its Subsidiaries (and Properties unitized therewith) have been maintained, operated and developed in a good and workmanlike manner and in conformity with all requirements of Governmental Authorities and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Oil and Gas Properties and other contracts and agreements forming a part of such Oil and Gas Properties. Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas Property of Borrower and its Subsidiaries is subject to having allowable production 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) and (ii) none of the wells comprising a part of the Oil and Gas Properties of Borrower and its Subsidiaries (or Properties unitized therewith) is deviated from the vertical more than the maximum permitted by requirements of Governmental Authorities, and such wells are, in fact, bottomed under and are producing from, the relevant Oil and Gas Properties (or in the case of wells located on Properties unitized therewith, such unitized Properties).

The Oil and Gas Properties of Borrower and its Subsidiaries are not subject to any contractual, or other arrangement for the sale of crude oil which cannot be canceled on ninety (90) days’ (or less) notice, unless the price provided for therein is equal to or greater than the prevailing market price in the vicinity. The Oil and Gas Properties of Borrower and its Subsidiaries are not subject to any gas sales contract that contains any material terms which are not customary in the industry within the region in which such Oil and Gas Properties affected thereby are located. The Oil and Gas Properties of Borrower and its Subsidiaries are not subject to any regulatory refund obligation and no facts exist which might cause the same to be imposed.

5.23 Purchasers of Production. The persons who are purchasing Borrower’s or the relevant Subsidiary’s interests in oil and gas produced from the Oil and Gas Properties of Borrower and its Subsidiaries as of the calendar month during which this Agreement is executed are identified on Schedule 5.23 attached hereto.

5.25 Existing Swap Transactions. Schedule 5.25, as of the date hereof, and, after the date hereof, each report required to be delivered by Borrower pursuant to Section 6.02(i), sets forth, a true and complete list of all Swap Transactions of Borrower and each Subsidiary, the material terms thereof (including the type, term, effective date, termination date and notional amounts or volumes), the net mark to market value thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement.

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, Administrative Agent may presume that such condition is satisfactory to such Lender or the L/C Issuer unless 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.

Upon receipt of any such notice of resignation, the Required Lenders, shall have the right, in consultation with 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 Agent gives notice of its resignation, then the retiring Agent may on behalf of Required Lenders, appoint a successor Agent meeting the qualifications set forth above; provided that if the retiring Agent shall notify 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 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 an Agent under any of the Loan Documents, the retiring Agent shall continue to hold such collateral security until such time as a successor Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through the retiring 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 to the retiring Agent as provided for above in this Section.

In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, Administrative Agent or the applicable Collateral 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 Administrative Agent or the applicable Collateral Agent shall have made any demand on 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, if applicable, and Agents (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer, if applicable, and Agents and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer, if applicable, and Agents under Sections 2.03(i) and (j), 2.09 and 10.04) allowed in such judicial proceeding; and

The parties to each assignment shall execute and deliver to Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount of $3,500; provided, however, that 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 Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Borrower. No such assignment shall be made to Borrower or any of 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 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

103

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, Borrower (at its expense) shall execute and deliver a Note to the assignee 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 Section 10.06(d).

(c) Register. Administrative Agent, acting solely for this purpose as an agent of Borrower, shall maintain at 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 Revolving Credit 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 Borrower, 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 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, Borrower or Administrative Agent, sell participations to any Person (other than a natural person or Borrower or any of 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 Revolving Credit Commitment and/or the Loans (including such Lender’s participations in L/C Obligations) 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) Borrower, Administrative Agent, the L/C Issuer and the Lenders 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 Section 10.06(e), 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 Section 10.06(b). 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 2.13 as though it were a Lender.

104

(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 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 Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of 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) Resignation as L/C Issuer. Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Revolving Credit Commitment and Loans pursuant to Section 10.06(b), Bank of America may, upon 30 days’ notice to Borrower and the Lenders, resign as L/C Issuer. In the event of any such resignation as L/C Issuer, Borrower shall be entitled to appoint from among Lenders a successor L/C Issuer hereunder; provided, however, that no failure by Borrower to appoint any such successor shall affect the resignation of Bank of America as L/C Issuer, 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 Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)). Upon the appointment of a successor L/C Issuer, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer, 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.

105

10.07 Treatment of Certain Information; Confidentiality. Each of Administrative Agent, 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 Borrower and its obligations, (g) with the consent of Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to Administrative Agent, any Lender, the L/C Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than Borrower.

For purposes of this Section, “Information” means all information received from Borrower or any Subsidiary relating to Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to Administrative Agent, any Lender or the L/C Issuer on a nonconfidential basis prior to disclosure by Borrower or any Subsidiary, provided that, in the case of information received from Borrower or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as 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 its own confidential information. Each of Administrative Agent, the Lenders and the L/C Issuer acknowledges that (a) the Information may include material non-public information concerning 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, after obtaining the prior written consent of Administrative Agent, 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 Borrower or any other Loan Party against any and

106

all of the obligations of Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or the L/C Issuer or any such Affiliate, 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 Borrower or such Loan Party 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 Borrower and 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 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 Borrower. In determining whether the interest contracted for, charged, or received by 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 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 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 Administrative Agent and when 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 Administrative Agent and each Lender, regardless of any investigation made by Administrative Agent or any Lender or on their behalf and notwithstanding that Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit

107

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 any Lender requests compensation under Section 3.04, or if 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 is a Defaulting Lender or if any other circumstance exists hereunder that gives Borrower the right to replace a Lender as a party hereto, then Borrower may, at its sole expense and effort, upon notice to such Lender and 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 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) Borrower shall have paid to 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 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; and

(d) 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 Borrower to require such assignment and delegation cease to apply.

108
