“Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the date of determination, the remainder of:

(i) the sum of

not reflected in such year-end reserve report, and (2) estimated increases in proved oil and gas reserves since such year-end due to exploration, development or exploitation activities or due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report), and decreased by, as of the date of determination, the estimated discounted future net revenues from (3) estimated proved oil and gas reserves reflected in such year-end report produced or disposed of since such year-end and (4) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year-end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report); provided that, in the case of each of the determinations made pursuant to clauses (1) through (4), such increases and decreases shall be as estimated by the Borrower’s petroleum engineers, unless there is a Material Change as a result of such acquisitions, dispositions or revisions, in which event the discounted future net revenues utilized for purposes of this clause (i)(a) shall be confirmed in writing an independent petroleum engineer, plus

minus (ii) the sum of

(a) minority interests, plus

(b) any net gas balancing liabilities of the Borrower and its Restricted Subsidiaries reflected in the Borrower’s latest audited Consolidated financial statements, plus

(c) to the extent included in (i)(a) above, the discounted future net revenues, calculated in accordance with SEC guidelines (utilizing the prices utilized in the Borrower’s year-end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Borrower and its Restricted

THE COMMITMENTS AND LOANS

2.01 Loans. (a) Subject to the terms and conditions set forth herein, each Fixed Rate Lender severally agrees to make a single loan to the Borrower on the Closing Date in an amount not to exceed such Fixed Rate Lender’s Fixed Rate Commitment Percentage of the Fixed Rate Facility. The Fixed Rate Borrowing shall consist of Fixed Rate Loans made simultaneously by the Fixed Rate Lenders in accordance with their respective Applicable Percentage of the Fixed Rate Facility. Amounts borrowed under this Section 2.01(a) and repaid or prepaid may not be reborrowed.

(b) Subject to the terms and conditions set forth herein, each Floating Rate Lender severally agrees to make a single loan to the Borrower on the Closing Date in an amount not to exceed such Floating Rate Lender’s Floating Rate Commitment. The Floating Rate Borrowing shall consist of Floating Rate Loans made simultaneously by the Floating Rate Lenders in

accordance with their respective Floating Rate Commitments. Amounts borrowed under this Section 2.01(b) and repaid or prepaid may not be reborrowed.

2.02 Borrowings, Conversions and Continuations of Loans.

(a) The Borrowings of Loans, each conversion of Floating Rate Loans from one Type to the other, and each continuation of Eurodollar Rate Loans shall be made upon the Borrower’s irrevocable notice to the Administrative Agent, which may be given by telephone. Each such notice must be received by the Administrative Agent not later than 11:00 a.m. (i) three Business Days prior to the requested date of any Borrowing of Loans, of any conversion to or continuation of Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans. Each telephonic notice by the Borrower pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the Administrative Agent of a written Loan Notice, appropriately completed and signed by a Responsible Officer of the Borrower. Each conversion or continuation of Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Each Loan Notice (whether telephonic or written) shall specify (i) whether the Borrower is requesting a Borrowing, a conversion of Floating Rate Loans from one Type to the other, or a continuation of Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) in the case of a conversion or continuation, the principal amount of Loans to be converted or continued, and (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted. If the Borrower fails to specify a Type of Loan in a Loan Notice with respect to Floating Rate Loans or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Floating Rate Loans shall be made as, or 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.

(b) Following receipt of a Loan Notice, the Administrative Agent shall promptly notify each Lender of the amount of its ratable share of the applicable Loans, and if no timely notice of a conversion or continuation is provided by the Borrower, the 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 the Borrowing, each Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 1:00 p.m. on the Closing Date. Upon satisfaction of the conditions set forth in Article IV, the Administrative Agent shall make all funds so received available to the Borrower in like funds as received by the Administrative Agent either by (i) crediting the account of the Borrower on the books of the Administrative Agent 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) the Administrative Agent by the Borrower.

(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 a Default, no Loans may be requested as, converted to or continued as Eurodollar Rate Loans without the consent of the Required Lenders.

(d) The Administrative Agent shall promptly notify the Borrower and the 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, the Administrative Agent shall notify the 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 Loans from one Type to the other, and all continuations of Loans as the same Type, there shall not be more than five Interest Periods in effect with respect to Loans.

2.03 Prepayments.

At any time on or after April 1, 2011, the Borrower may prepay the Fixed Rate Loans at its option, in whole at any time or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice to the Administrative Agent, at the following prepayment prices (expressed as a percentage of principal amount), plus accrued and unpaid interest to the prepayment date, if prepaid during the twelve-month period beginning on April 1 of the years indicated below:

(iii) Any partial prepayment shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. 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. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Applicable Percentage of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 3.05.

(b) Clean-Up Call. If after giving effect to the Initial Exchange, the aggregate amount of Fixed Rate Loans or Floating Rate Loans is less than 10% of the aggregate principal amount of Fixed Rate Loans or Floating Rate Loans, as applicable, made on the Closing Date (the “Affected Tranche”), the Borrower may at its option prepay Loans of the Affected Tranche or Affected Tranches in whole (but not in part) at 100% of the outstanding principal amount thereof, together with interest thereon to the date of payment, provided that any such prepayment will be made, if at all, not later than 60 days after the Initial Exchange Date.

(c) Mandatory. The Borrower shall, within 7 Business Days of the date on which the aggregate amount of Excess Proceeds exceeds $20,000,000, prepay Loans in an aggregate amount equal to the amount of Excess Proceeds at 100% of the principal amount of such Loans plus accrued and unpaid interest, if any, on the amount so prepaid to the date of payment. Any such prepayment shall be applied ratably to all Loans, treated for this purpose as a single Tranche. Any Lender may elect, on not less than 4 Business Days’ prior written notice to the Administrative Agent with respect to any mandatory prepayment made pursuant to this Section 2.03(c) not to have such prepayment applied to such Lender’s Loans, in which case, the full amount not so applied shall be retained by the Borrower.

(d) Applications. Prepayments made pursuant to this Section 2.03 shall be applied ratably to the Loans of the Lenders of the Tranche so repaid.

2.04 Repayment of Loans.

(a) The Fixed Rate Loans will mature and be paid in full on the Fixed Rate Maturity Date.

(b) The Floating Rate Loans will mature and be paid in full on the Floating Rate Maturity Date.

(c) The Final Maturity Date for all Loans tendered in the Initial Exchange shall be deemed to be the closing date for the Initial Exchange.

2.05 Interest.

(a) Fixed Rate Loans. Subject to the provisions of subsection (c) below, each Fixed Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Applicable Fixed Rate for such Interest Period. For any Interest Period prior to the fourth anniversary of the Closing Date, the Borrower may, at its option, elect to pay interest on the Fixed Rate Loans (i) entirely in cash (“Cash Interest”, and any such Interest Period for which Cash Interest is elected in accordance with the next succeeding sentence, a

“Cash Interest Period”), in which case interest for such Interest Period shall be payable in cash, or (ii) entirely in kind (“PIK Interest”; and any such Interest Period for which PIK Interest is elected in accordance with the next succeeding sentence, a “PIK Interest Period”), in which case interest for such Interest Period shall be payable by increasing the outstanding principal amount of the Loans by the amount of interest accrued during such Interest Period. The Borrower must elect the form of payment of interest for the Fixed Rate Loans, whether Cash Interest or PIK Interest, with respect to each Interest Period prior to the fourth anniversary of the Closing Date by delivering a notice to the Administrative Agent five Business Days prior to the start of such Interest Period. The Administrative Agent shall promptly deliver a corresponding notice to each Lender. In the absence of such an election for any Interest Period, interest on the Loans shall be payable according to the election for the previous Interest Period. “Applicable Fixed Rate” means (x) during any Cash Interest Period, 8.625% and (y) during any PIK Interest Period, 9.375% plus, in each case, the Incremental Margin applicable at such time.

(b) Floating Rate Loans. Subject to the provisions of subsection (c) 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 Floating Rate Margin 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 Floating Rate Margin. “Applicable Floating Rate Margin” means (x) for any Eurodollar Rate Loan, 3.625% and (y) for any Base Rate Loan, 2.625% plus, in each case, the Incremental Margin applicable at such time.

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

(ii) If any amount (other than principal of any Loan) payable by the Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders (or automatically upon and during the continuance of (x) any Default under clause (h) of Section 8.01 or (y) any failure to pay principal of any Loan when due), 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) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(d) 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.

2.06 Fees. The Borrower shall pay to the Administrative Agent, the Lead Arranger and the Lenders, as applicable, for their own respective accounts fees separately agreed among

such parties in writing. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

2.07 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. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

2.08 Evidence of Debt.

The Loans made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Loans made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.09 Payments Generally; Administrative Agent’s Clawback.

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

(b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the Closing Date that such Lender will not make available to the Administrative Agent such Lender’s share of the Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender

has not in fact made its share of the Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing, and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in the Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

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

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

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

(d) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans and to make payments pursuant to Section 10.04(c) are several and not joint. The failure of any Lender to make any Loan 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 or to make its payment under Section 10.04(c).

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

2.10 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans made by it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Loans 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 of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided that:

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

(ii) the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans

to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this Section shall apply).

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

ARTICLE III.
TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

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

deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent or, such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

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

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

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

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

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

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

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

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

3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of

the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted.

3.03 Inability to Determine Rates. If the Required Lenders determine that for any reason in connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan, or (c) the Eurodollar Rate for any requested Interest Period with respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent (upon the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in the amount specified therein.

3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

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

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

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

(iii) impose on any Lender or the London interbank market any other condition, cost or expense affecting this Agreement or Eurodollar Rate Loans made by such Lender;

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 reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or any other amount) then, upon request of such Lender, the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any Lending Office of such Lender or such Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in subsection (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender, 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 to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of such Lender’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

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

3.05 Compensation for Losses. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Floating Rate Loan (other than pursuant to the Initial Exchange) other than a Base Rate Loan on a day other than the

last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

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

(c) any assignment of a Eurodollar Rate Loan on a day other than the last day of the Interest Period therefor as a result of a request by the Borrower pursuant to Section 10.13;

including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

3.06 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, or if any Lender gives a notice pursuant to Section 3.02, then such Lender shall use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Sections 3.01 or 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 3.04, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, the Borrower may replace such Lender in accordance with Section 10.13.

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

(k) promptly, such additional information regarding the business, financial or corporate affairs of the Borrower or any Restricted Subsidiary, or compliance with the terms of the Loan Documents, as the Administrative Agent may from time to time reasonably request.

Documents required to be delivered pursuant to Section 6.01(a) or (b) or Section 6.02(c) (to the extent any such documents are included in materials otherwise filed with the SEC) may be delivered electronically and if so delivered, shall be deemed to have been delivered on the date (i) on which the Borrower posts such documents, or provides a link thereto on the Borrower’s website on the Internet at the website address listed on Schedule 10.02; or (ii) on which such documents are posted on the Borrower’s behalf on an Internet or intranet website, if any, to which each Lender and the Administrative Agent have access (whether a commercial, third-party website or whether sponsored by the Administrative Agent); provided that: (i) the Borrower shall deliver paper copies of such documents to the Administrative Agent or any Lender that requests the Borrower to deliver such paper copies until a written request to cease delivering paper copies is given by the Administrative Agent or such Lender and (ii) the Borrower shall notify the Administrative Agent and each Lender (by telecopier or electronic mail) of the posting of any such documents and provide to the Administrative Agent by electronic mail electronic versions (i.e., soft copies) of such documents. Notwithstanding anything contained herein, in every instance the Borrower shall be required to provide paper copies of the Compliance Certificates required by Section 6.02(a) to the Administrative Agent. Except for such Compliance Certificates, the Administrative Agent shall have no obligation to request the delivery or to maintain copies of the documents referred to above, and in any event shall have no responsibility to monitor compliance by the Borrower with any such request for delivery, and each Lender shall be solely responsible for requesting delivery to it or maintaining its copies of such documents.

The Borrower hereby acknowledges that (a) the Administrative Agent and/or Lead Arranger will make available to the Lenders materials and/or information provided by or on

behalf of the Borrower hereunder (collectively, “Borrower Materials”) either by posting the Borrower Materials on IntraLinks or another similar electronic system (the “Platform”) or by delivery or electronic communication to the applicable Lenders and (b) certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the Borrower or its securities except as contemplated below) (each, a “Public-Side Lender”). The Borrower hereby agrees that so long as the Borrower is the issuer of any outstanding debt or equity securities that are registered or issued pursuant to a private offering or is actively contemplating issuing any such securities (x) all Borrower Materials that are to be posted on the Platform shall be clearly and conspicuously marked “PUBLIC-SIDE” which, at a minimum, shall mean that the words “PUBLIC-SIDE” shall appear prominently on the first page thereof; (y) by marking Borrower Materials “PUBLIC-SIDE,” the Borrower shall be deemed to have authorized the Administrative Agent, the Lead Arranger and the Lenders to treat such Borrower Materials as not containing any material non-public information with respect to the Borrower or its securities for purposes of United States Federal and state securities laws (provided, however, that (A) prior to the creation of a Public Market, Lenders shall treat such Borrower Materials as containing material non-public information with respect to the Borrower and its Subsidiaries (“MNPI”), and the Borrower shall be deemed to have represented to the Lenders that it expects such Borrower Materials will cease to be MNPI at the time of creation of a Public Market and (B) to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 10.07); and (z) any Borrower Materials that are not marked “PUBLIC-SIDE” as contemplated above shall be treated as containing MNPI, shall not be posted on the Platform and shall be available to Lenders only upon request therefor (which request may apply generally to all such Borrower Materials). Any such request shall constitute a confirmation from the applicable Lender that it has compliance procedures for dealing with such MNPI, and that it will use and maintain such information only in compliance with those procedures, its contractual obligations and applicable law, including federal and state securities laws.

Each Public-Side Lender shall designate individuals or advisors authorized to act on behalf of the Public-Side Lender to receive Borrower Materials not designated as “PUBLIC-SIDE” pursuant to the immediately preceding paragraph, including any notices pursuant to Section 6.03.

6.03 Notices. Promptly notify the Administrative Agent and each Lender:

(a) of the occurrence of any Default;

(b) of any matter that has resulted or could reasonably be expected to result in a Material Adverse Effect, including (i) breach or non-performance of, or any default under, a Contractual Obligation of the Borrower or any Restricted Subsidiary; (ii) any dispute, litigation, investigation, proceeding or suspension between the Borrower or any Restricted Subsidiary and any Governmental Authority; or (iii) the commencement of, or any material development in, any litigation or proceeding affecting the Borrower or any Restricted Subsidiary, including pursuant to any applicable Environmental Laws;

(d) of any material change in accounting policies or financial reporting practices by the Borrower or any Subsidiary;

(f) of the date on which Excess Proceeds from Asset Sales exceeds $20,000,000, which the Borrower is required to use to make a mandatory prepayment pursuant to Section 2.03(c).

Each notice pursuant to this Section 6.03 (other than Section 6.03(f)) shall be accompanied by a statement of a Responsible Officer of the Borrower setting forth details of the occurrence referred to therein and stating what action the Borrower has taken and proposes to take with respect thereto. Each notice pursuant to Section 6.03(a) shall describe with particularity any and all provisions of this Agreement and any other Loan Document that have been breached.

6.04 Payment of Obligations. Pay and discharge as the same shall become due and payable, (a) all tax liabilities, assessments and governmental charges or levies upon it or its properties or assets, unless the same are being contested in good faith by appropriate proceedings diligently conducted and adequate reserves in accordance with GAAP are being maintained by the Borrower or such Restricted Subsidiary; and (b) all lawful claims which, if unpaid, would by law become a Lien upon its property, except, in the case of (a) or (b), for such amounts that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

6.05 Preservation of Existence, Etc. (a) Preserve, renew and maintain in full force and effect its legal existence and good standing under the Laws of the jurisdiction of its organization except in a transaction permitted by Sections 7.03 or 7.04; (b) take all reasonable action to maintain all rights, privileges, permits, licenses and franchises necessary or desirable in the normal conduct of its business, except to the extent that failure to do so could not reasonably be expected to have a Material Adverse Effect; and (c) preserve or renew all of its registered patents, trademarks, trade names and service marks, the non-preservation of which could reasonably be expected to have a Material Adverse Effect.

6.06 Maintenance of Properties. (a) Maintain, preserve and protect all of its material properties and equipment necessary in the operation of its business in good working order and condition, ordinary wear and tear excepted; (b) make all necessary repairs thereto and renewals and replacements thereof except where the failure to do so could not reasonably be expected to have a Material Adverse Effect; and (c) use the standard of care typical in the industry in the operation and maintenance of its facilities.

6.07 Maintenance of Insurance. Maintain (at its own expense) insurance with financially sound and reputable insurance companies, as well as insurance in such amounts, with such limitations or deductibles, against such risks, and in such form as are customarily

maintained by companies of established repute engaged in the same or similar businesses operating in the same or similar locations.

6.08 Compliance with Laws. Comply in all material respects with the requirements of all Laws and all orders, writs, injunctions and decrees applicable to it or to its business or property, except in such instances in which (a) such requirement of Law or order, writ, injunction or decree is being contested in good faith by appropriate proceedings diligently conducted; or (b) the failure to comply therewith could not reasonably be expected to have a Material Adverse Effect.

6.09 Books and Records. (a) Maintain proper books of record and account, in which full, true and correct entries in conformity with GAAP consistently applied shall be made of all financial transactions and matters involving the assets and business of the Borrower or such Subsidiary, as the case may be; and (b) maintain such books of record and account in material conformity with all applicable requirements of any Governmental Authority having regulatory jurisdiction over the Borrower or such Subsidiary, as the case may be.

6.10 Inspection Rights. Permit representatives and independent contractors of the Administrative Agent and each Lender to visit and inspect any of its properties, to examine its corporate, financial and operating records, and make copies thereof or abstracts therefrom, and to discuss its affairs, finances and accounts with its directors, officers, and independent public accountants, all at the expense of the Borrower and at such reasonable times during normal business hours and as often as may be reasonably desired, upon reasonable advance notice to the Borrower; provided, however, that when an Event of Default exists the Administrative Agent or any Lender (or any of their respective representatives or independent contractors) may do any of the foregoing at the expense of the Borrower at any time during normal business hours and without advance notice.

6.11 Use of Proceeds. The Borrower shall apply the proceeds of the Credit Extensions to (i) refinance the Borrower’s existing bridge credit facility under the Existing Agreement, (ii) pay certain fees and expenses incurred in connection with entering into this Agreement, (iii) provide working capital for the Borrower and its Subsidiaries including the issuance of letters of credit, capital expenditures, and other lawful corporate purposes and (iv) finance permitted acquisitions by the Borrower and its Subsidiaries of oil and gas properties and other assets related to the exploration, production and development of oil and gas properties.

6.12 Covenant to Guarantee Obligations. Upon the formation or acquisition of any new direct or indirect Restricted Subsidiary (excluding (i) any Foreign Subsidiary and (ii) any Immaterial Subsidiary) by any Loan Party, then the Borrower shall, at the Borrower’s expense within 20 days after such formation or acquisition (or such longer period as the Administrative Agent may in its discretion approve), cause such Restricted Subsidiary to duly execute and deliver to the Administrative Agent a guaranty or guaranty supplement, in form and substance satisfactory to the Administrative Agent, guaranteeing the other Loan Parties’ obligations under the Loan Documents.

6.14 [Reserved]

6.15 Exchange Notes.

(a) At any time after the one-year anniversary of the Closing Date but not later than April 30, 2008, the Borrower shall make an offer to all the Lenders under this Agreement to exchange the Loans for Initial Exchange Notes (such exchange, the “Initial Exchange”, and the date of such exchange, the “Initial Exchange Date”) having a principal amount equal to that of the Loans exchanged therefor and issued pursuant to the Initial Exchange Note Indenture. The Initial Exchange will be made pursuant to an offering memorandum customary for transactions pursuant to Rule 144A and relating to the Initial Exchange Notes and will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 and any other securities laws and regulations thereunder. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Agreement solely with respect to the Initial Exchange, the Borrower will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations with respect to the Initial Exchange described in this Agreement by virtue thereof. Each Lender participating in the Initial Exchange must be eligible to purchase securities in an offering conducted pursuant to Rule 144A. For avoidance of doubt, only one Initial Exchange will occur during the term of the Loans.

(b) Failure to make the Initial Exchange will not constitute a Default under this Agreement. The Loans and any Initial Exchange Notes subsequently issued under the Initial Exchange Note Indenture will be separate debt obligations of the Borrower and will not be treated as a single class, including, without limitation, for purposes of waivers, amendments, redemptions and offers to purchase.

(c) If the Initial Exchange Date does not occur on or prior to May 31, 2008, the Borrower shall pay liquidated damages to the Lenders with respect to the first 90-day period immediately following such date in an amount equal to 0.25% per annum on the outstanding principal amount of the Loans. The amount of liquidated damages will increase by an additional 0.25% per annum on the outstanding principal amount of the Loans with respect to each subsequent 90-day period until the occurrence of the Initial Exchange, up to a maximum amount of liquidated damages under this subsection of 0.50% per annum. Any such liquidated damages shall be payable to but excluding the Initial Exchange Date and as provided in Section 2.05.

(d) The Initial Exchange will be made solely pursuant to the offering memorandum described above and an offer to exchange and this Agreement shall not constitute an offer to exchange the Loans or an offer of the Initial Exchange Notes.

(e) The Initial Exchange Note Indenture shall provide that no later than November 30, 2008 the Borrower shall offer an exchange of the Initial Exchange Notes for notes registered with the SEC (the “Second Exchange Notes”), which Second Exchange Notes shall have substantially similar terms as the Initial Exchange Notes. The Initial Exchange Note Indenture shall further provide that (i) upon failure to comply with the foregoing requirements (a “Registration Default”), the Borrower shall pay liquidated damages to each holder of Initial Exchange Notes with respect to the first 90-day period immediately following the occurrence of the first Registration Default in an amount equal to 0.25% per annum on the principal amount of Initial Exchange Notes held by such holder and (ii) the amount of such liquidated damages shall increase by an additional 0.25% per annum on the principal amount of Initial Exchange Notes with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of liquidated damages for all Registration Defaults of 0.50% per annum.

6.16 Change of Control.

(a) If a Change of Control occurs, each Lender will have the right to require the Borrower to prepay all of such Lender’s Loans at a prepayment price in cash equal to 101% of the principal amount of such Lender’s Loans, plus accrued and unpaid interest to the date of prepayment.

(b) No later than the date that is 60 days after any Change of Control, the Borrower will mail a notice (the “Change of Control Offer”) to each Lender, with a copy to the Administrative Agent:

(i) stating that a Change of Control has occurred or may occur and that such Lender has the right to require the Borrower to prepay such Lender’s Loans at a prepayment price in cash equal to 101% of the principal amount plus accrued and unpaid interest to, but not including, the date of prepayment (the “Change of Control Payment”);

(ii) stating the prepayment date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the “Change of Control Payment Date”);

(iii) describing the circumstances and relevant facts regarding the transaction or transactions that constitute the Change of Control;

(iv) describing the procedures determined by the Borrower, consistent with this Agreement, that a Lender must follow in order to have its Loans prepaid; and

(v) if such notice is mailed prior to the occurrence of a Change of Control, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control.

(c) On the Change of Control Payment Date, if the Change of Control shall have occurred, the Borrower will, to the extent lawful pay to the Administrative Agent for application

to the repayment of all Loans properly submitted for prepayment pursuant to the Change of Control Offer an amount equal to the Change of Control Payment in respect of all Loans so submitted.

(d) The Borrower will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Borrower and prepays all Loans validly submitted for prepayment under such Change of Control Offer.

ARTICLE VII.
NEGATIVE COVENANTS

So long as any Lender shall have any Commitment hereunder or any Loan or other Obligation hereunder shall remain unpaid or unsatisfied, the Borrower shall not, nor shall it permit any Restricted Subsidiary to, directly or indirectly:

7.01 Liens. (a) The Borrower will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly, create or incur, in order to secure any Indebtedness, any Lien of any kind, other than Permitted Liens, upon any property or assets (including any intercompany notes) of the Borrower or any Restricted Subsidiary owned on the date hereof or acquired after the date hereof, or assign or convey, in order to secure any Indebtedness, any right to receive any income or profits therefrom, unless the Loans (or a Guarantee in the case of Liens of a Guarantor) are directly secured equally and ratably with (or, in the case of Subordinated Indebtedness, prior or senior thereto, with the same relative priority as the Loans shall have with respect to such Subordinated Indebtedness) the Indebtedness secured by such Lien.

(b) Notwithstanding the foregoing, any Lien securing the Loans or a Guarantee granted pursuant to clause (a) above shall be automatically and unconditionally released and discharged upon:

(i) any sale, exchange or transfer to any Person not an Affiliate of the Borrower of the property or assets secured by such Lien,

(ii) any sale, exchange or transfer to any Person not an Affiliate of the Borrower of all of the Capital Stock held by the Borrower or any Restricted Subsidiary in, or all or substantially all the assets of, any Restricted Subsidiary creating such Lien, or

(iii) with respect to any Lien securing a Guarantee, the release of such Guarantee in accordance with the terms of this Agreement.

7.02 Indebtedness. (a) The Borrower will not, and will not cause or permit any of its Restricted Subsidiaries to, create, issue, incur, assume, guarantee or otherwise in any manner become directly or indirectly liable for the payment of or otherwise incur, contingently or otherwise (collectively, “incur”), any Indebtedness (including any Acquired Debt and the issuance of Disqualified Stock), unless such Indebtedness is incurred by the Borrower or any Guarantor and, in each case, the Borrower’s Consolidated Fixed Charge Coverage Ratio for the

most recent four full fiscal quarters for which financial statements are available immediately preceding the incurrence of such Indebtedness taken as one period is at least equal to or greater than 2.50:1.

(b) Notwithstanding the foregoing, the Borrower and, to the extent specifically set forth below, the Restricted Subsidiaries may incur each and all of the following (collectively, the “Permitted Debt”):

(i) Indebtedness of the Borrower or any Guarantors (whether as borrowers or guarantors) under one or more Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (i) not to exceed the greater of (x) $750,000,000 and (y) 30.0% of Adjusted Consolidated Net Tangible Assets;

(ii) Indebtedness of the Borrower or any Guarantor pursuant to the Loans of either series or any Exchange Notes issued in exchange for the Loans or the Initial Exchange Notes;

(iii) Indebtedness of the Borrower or any Guarantor outstanding on the date hereof, and not otherwise referred to in this definition of “Permitted Debt;”

(iv) intercompany Indebtedness between or among the Borrower and any of its Restricted Subsidiaries; provided, however, that:

(A) if the Borrower or any Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations with respect to the Loans, in the case of the Borrower, or the Loan Guarantee, in the case of a Guarantor; and

(B) (1) any subsequent issuance or transfer of Capital Stock that results in any such Indebtedness being held by a Person other than the Borrower or a Restricted Subsidiary thereof (other than pursuant to a Credit Facility) and (2) any sale or other transfer of any such Indebtedness to a Person that is not either the Borrower or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Borrower or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (iv);

(v) guarantees by the Borrower or any Guarantor of any Indebtedness of the Borrower or any of the Guarantors which is permitted to be incurred under this Agreement;

(vi)

(A) obligations pursuant to Interest Rate Agreements entered into in the ordinary course of business with respect to Indebtedness permitted by this Agreement;

(B) obligations under currency exchange contracts entered into in the ordinary course of business; and

(C) obligations pursuant to hedging arrangements (including, without limitation, swaps, caps, floors, collars, options and similar agreements) entered into in the ordinary course of business for the purpose of protecting, on a net basis, against price risks, basis risks, or other risks encountered in the Oil and Gas Business;

(vii) Indebtedness of the Borrower or any Restricted Subsidiary represented by Capital Lease Obligations (whether or not incurred pursuant to Sale Leaseback Transactions) or Purchase Money Obligations or other Indebtedness incurred or assumed in connection with the acquisition or development of real or personal, movable or immovable, property in each case incurred for the purpose of financing or refinancing all or any part of the purchase price or cost of construction or improvement of property used in the business of the Borrower, in an aggregate principal amount pursuant to this clause (vii) (together with the aggregate principal amount of any Permitted Refinancing Indebtedness in respect of Indebtedness originally incurred pursuant to this clause (vii)) not to exceed $50,000,000 outstanding at any time; provided that the principal amount of any Indebtedness permitted under this clause (vii) did not in each case at the time of incurrence exceed the Fair Market Value, as determined by the Borrower in good faith, of the acquired or constructed asset or improvement so financed;

(viii) Indebtedness of the Borrower or any Guarantor in connection with

(A) one or more standby letters of credit issued for the account of the Borrower or a Guarantor in the ordinary course of business and

(B) other letters of credit, surety, bid, performance, appeal or similar bonds, bankers’ acceptances, completion guarantees or similar instruments; provided that, in each case contemplated by this clause (viii), upon the drawing of such letters of credit or other instrument, such obligations are reimbursed within 30 days following such drawing; provided, further, that with respect to clauses (A) and (B), such Indebtedness is not in connection with the borrowing of money or the obtaining of advances or credit;

(ix) obligations relating to oil or gas balancing positions arising in the ordinary course of business;

(x) Indebtedness of the Borrower or any Restricted Subsidiary arising from agreements for indemnification or purchase price adjustment obligations or similar obligations, earn-outs or other similar obligations or from guarantees or letters of credit, surety bonds or performance bonds securing any obligation of the Borrower or a Restricted Subsidiary pursuant to such an agreement, in each case incurred or assumed in connection with the acquisition or disposition of any business, assets or Capital Stock of a Restricted Subsidiary;

(xi) Permitted Refinancing Indebtedness of the Borrower or any Restricted Subsidiary issued in exchange for, or the net proceeds of which are used to renew, extend, substitute, defease, refund, refinance or replace, any Indebtedness, including any Disqualified Stock, incurred pursuant to Section 7.02(a) and clauses (ii), (iii) and (vii) of this Section 7.02(b);

(xii) the incurrence by the Borrower or any of its Restricted Subsidiaries of Acquired Debt in connection with a transaction meeting either one of the financial tests set forth in Section 7.03(a)(iii);

(xiii) any obligation arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five business days of incurrence; and

(xiv) Indebtedness of the Borrower or any Restricted Subsidiary in addition to that described in clauses (i) through (xiii) above, and any renewals, extensions, substitutions, refinancings or replacements of such Indebtedness, so long as the aggregate principal amount of all such Indebtedness shall not exceed $40,000,000 outstanding at any one time in the aggregate.

(c) For purposes of determining compliance with this Section, in the event that an item of Indebtedness meets the criteria of more than one of the types of Indebtedness permitted by this Section, the Borrower in its sole discretion may classify or reclassify such item of Indebtedness and only be required to include the amount of such Indebtedness as one of such types (or to divide such Indebtedness between two or more of such types); provided that any Indebtedness under the Senior Credit Facility which is in existence on the Closing Date shall be deemed to have been incurred pursuant to clause (i) of this subsection (b) above rather than subsection (a) above.

(d) Indebtedness permitted by this Section need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness.

(e) Accrual of interest, accretion of principal or liquidation preference (or similar amount) in respect of Preferred Stock or amortization of original issue discount, and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the accretion or payment of dividends on any Disqualified Stock or Preferred Stock (including without limitation the Series A Preferred Stock) in the form of additional shares of the same class of Disqualified Stock or Preferred Stock and the issuance of additional shares of Series A Preferred Stock pursuant to warrants issued and outstanding on the Closing Date will not be deemed to be an incurrence of Indebtedness for purposes of this covenant; provided, in each such case, that the amount thereof as accrued shall be included as required in the calculation of the Consolidated Fixed Charge Coverage Ratio of the Borrower.

(f) For purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the date that such Indebtedness was incurred.

(g) If Indebtedness is secured by a letter of credit that serves only to secure such Indebtedness, then the total amount deemed incurred shall be equal to the greater of (x) the principal of such Indebtedness and (y) the amount that may be drawn under such letter of credit.

(h) The amount of Indebtedness issued at a price less than the amount of the liability thereof shall be determined in accordance with GAAP.

7.03 Consolidation, Merger and Sale of Assets.

(a) The Borrower will not, in a single transaction or through a series of related transactions, consolidate with or merge with or into any other Person or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person or group of Persons, or permit any of its Restricted Subsidiaries to enter into any such transaction or series of transactions, if such transaction or series of transactions, in the aggregate, would result in a sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Borrower and its Restricted Subsidiaries on a Consolidated basis to any other Person or group of Persons (other than the Borrower or a Guarantor), unless at the time and after giving effect thereto:

(i) either (A) the Borrower will be the continuing corporation or (B) the Person (if other than the Borrower) formed by such consolidation or into which the Borrower is merged or the Person which acquires by sale, assignment, conveyance, transfer, lease or disposition all or substantially all of the properties and assets of the Borrower and its Restricted Subsidiaries on a Consolidated basis (the “Surviving Entity”) will be a corporation, limited liability company or limited partnership (provided that in the event the Surviving Entity is a limited partnership, then a Subsidiary of the Surviving Entity that is a corporation or limited liability company shall execute an amendment to this Agreement pursuant to which it shall become a co-obligor of the Surviving Entity’s obligations under the Loans and this Agreement) duly organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia and the Surviving Entity expressly assumes, by an amendment to this Agreement, in a form reasonably satisfactory to the Administrative Agent, all the obligations of the Borrower under the Loans and this Agreement, and the Loans and this Agreement will remain in full force and effect as so supplemented;

(ii) immediately after giving effect to such transaction on a pro forma basis (and treating any Indebtedness not previously an obligation of the Borrower or any of its Restricted Subsidiaries which becomes the obligation of the Borrower or any of its Restricted Subsidiaries as a result of such transaction as having been incurred at the time of such transaction), no Default or Event of Default will have occurred and be continuing;

(iii) immediately after giving effect to such transaction on a pro forma basis (on the assumption that the transaction occurred on the first day of the four-quarter period for which financial statements are available ending immediately prior to the consummation of such transaction with the appropriate adjustments with respect to the transaction being included in such pro forma calculation), the Borrower (or the Surviving Entity if the Borrower is not the continuing obligor under this Agreement) (A) could incur $1.00 of additional Indebtedness (other than Permitted Debt) under the provisions of Section 7.02 or (B) have a Consolidated Fixed Charge Coverage Ratio not less than the Consolidated Fixed Charge Coverage Ratio of the Borrower immediately prior to such transaction;

(iv) unless the Borrower is the continuing obligor under this Agreement, at the time of the transaction, each Guarantor, if any, unless it is the other party to the transactions described above, will have by amendment to this Agreement confirmed that its Guarantee shall apply to the Surviving Entity’s obligations under this Agreement and the Loans;

(v) at the time of the transaction, if any of the property or assets of the Borrower or any of its Restricted Subsidiaries would thereupon become subject to any Lien, the provisions of Section 7.01 are complied with; and

(vi) at the time of the transaction, the Borrower or the Surviving Entity will have delivered, or caused to be delivered, to the Administrative Agent, in form and substance reasonably satisfactory to the Administrative Agent, an officers’ certificate and an opinion of counsel, each to the effect that such consolidation, merger, transfer, sale, assignment, conveyance, transfer, lease or other transaction and the amendment to this Agreement in respect thereof comply with the terms of this Agreement.

(b) Each Guarantor will not, and the Borrower will not permit a Guarantor to, in a single transaction or through a series of related transactions, (x) consolidate with or merge with or into any other Person (other than the Borrower or any other Guarantor) or (y) sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person or group of Persons (other than the Borrower or any other Guarantor) or permit any of its Restricted Subsidiaries to enter into any such transaction or series of transactions if such transaction or series of transactions, in the aggregate, in the case of clause (y) would result in a sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Guarantor and its Restricted Subsidiaries on a Consolidated basis to any other Person or group of Persons (other than the Borrower or any Guarantor), unless at the time and after giving effect thereto

(i) either (A) the Guarantor or the Borrower will be the continuing Person in the case of a merger involving the Guarantor or (B) the Person (if other than the Guarantor) formed by such consolidation or into which such Guarantor is merged or the Person which acquires by sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Guarantor and its Restricted Subsidiaries on a Consolidated basis (the “Surviving Guarantor Entity”) expressly assumes, by an amendment to this Agreement, in a form reasonably satisfactory to the

Administrative Agent, all the obligations of such Guarantor under its Guarantee of the Loans and this Agreement, and such Guarantee and this Agreement will remain in full force and effect;

(ii) immediately before and immediately after giving effect to such transaction on a pro forma basis, no Default or Event of Default will have occurred and be continuing; and

(iii) at the time of the transaction such Guarantor or the Surviving Guarantor Entity will have delivered, or caused to be delivered, to the Administrative Agent, in form and substance reasonably satisfactory to the Administrative Agent, an officers’ certificate and an opinion of counsel, each to the effect that such consolidation, merger, transfer, sale, assignment, conveyance, lease or other transaction and the supplemental indenture in respect thereof comply with this Agreement;

provided, however, that this Section 7.03(b) shall not apply to any Guarantor whose Guarantee of the Loans is unconditionally released and discharged in accordance with Section 9.10 of this Agreement.

related transactions is fair to the Borrower or such Restricted Subsidiary from a financial point of view;

provided, however, that this provision shall not apply to:

(B) the Designation Amount is less than $1,000;

(vi) such Unrestricted Subsidiary is not a party to any agreement, contract, arrangement or understanding at such time with the Borrower or any Restricted Subsidiary unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Borrower or such Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Borrower or, in the event such condition is not satisfied, the value of such agreement, contract, arrangement or understanding to such Unrestricted Subsidiary shall be deemed a Restricted Payment.

In the event of any such Designation, the Borrower shall be deemed, for all purposes of this Agreement, to have made an Investment equal to the Designation Amount that constitutes a Restricted Payment pursuant to Section 7.05.

(b) The Borrower shall not and shall not cause or permit any Restricted Subsidiary to at any time

(i) provide credit support for, guarantee or subject any of its property or assets (other than the Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, any Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness), provided, however, that the provisions of this clause (b)(i) shall not be deemed to prevent Permitted Investments in Unrestricted Subsidiaries that are otherwise allowed under this Agreement, or

(ii) be directly or indirectly liable for any Indebtedness of any Unrestricted Subsidiary.

(c) For purposes of the foregoing, the Designation of a Subsidiary of the Borrower as an Unrestricted Subsidiary shall be deemed to be the Designation of all of the Subsidiaries of such Subsidiary as Unrestricted Subsidiaries. Unless so designated as an Unrestricted

Subsidiary, any Person that becomes a Subsidiary of the Borrower will be classified as a Restricted Subsidiary.

(d) The Borrower may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a “Revocation”) if:

(e) All Designations and Revocations must be evidenced by a resolution of the board of directors of the Borrower delivered to the Administrative Agent certifying compliance with the foregoing provisions of this covenant.

7.10 Payments for Consent.

Neither the Borrower nor any of its Restricted Subsidiaries will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Lender for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Agreement or the Loans of either Tranche unless such consideration is offered to be paid or is paid to all holders of Loans of such Tranche that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

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

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

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

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

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

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

9.04 Reliance by Administrative Agent.

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

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

9.06 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent

shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

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

9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, neither the Lead Arranger nor any Co-Arranger shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except as expressly provided herein or therein.

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

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans 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 and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Sections 2.06 and 10.04) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent

and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.06 and 10.04.

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

9.10 Guaranty Matters. The Guarantee of a Guarantor will be released automatically:

(a) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Borrower or a Restricted Subsidiary, if the sale or other disposition does not violate Section 7.04 hereof;

(b) in connection with any sale or other disposition of all of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Borrower or a Restricted Subsidiary, if the sale or other disposition does not violate Section 7.04 hereof; or

(c) if the Borrower designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with Section 7.09 hereof.

In each case as specified in this Section 9.10, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section 9.10.

ARTICLE X.
MISCELLANEOUS

10.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent to any departure by the Borrower or any other Loan Party therefrom, shall be effective unless in writing signed by the Required Lenders and the Borrower or the applicable Loan Party, as the case may be, and acknowledged by the Administrative Agent, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no such amendment, waiver or consent shall:

10.02 Notices; Effectiveness; Electronic Communication.

(a) Notices Generally. Except in the case of notices and other communications expressly permitted to be given by telephone (and except as provided in subsection (b) below), all notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopier as follows, and all notices and other communications expressly permitted hereunder to be given by telephone shall be made to the applicable telephone number, as follows:

Notices sent by hand or overnight courier service, or mailed by certified or registered mail, shall be deemed to have been given when received; notices sent by telecopier shall be deemed to have been given when sent (except that, if not given during normal business hours for the recipient, shall be deemed to have been given at the opening of business on the next business day for the

recipient). Notices delivered through electronic communications to the extent provided in subsection (b) below, shall be effective as provided in such subsection (b).

(b) Electronic Communications. Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent, provided that the foregoing shall not apply to notices to any Lender pursuant to Article II if such Lender, as applicable, has notified the Administrative Agent that it is incapable of receiving notices under such Article by electronic communication. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications.

Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement), provided that if such notice or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient, and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available and identifying the website address therefor.

(c) The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. In no event shall the Administrative Agent or any of its Related Parties (collectively, the “Agent Parties”) have any liability to the Borrower, any Lender, or any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or otherwise) arising out of the Borrower’s or the Administrative Agent’s transmission of Borrower Materials through the Internet, except to the extent that such losses, claims, damages, liabilities or expenses are determined by a court of competent jurisdiction by a final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Agent Party; provided, however, that in no event shall any Agent Party have any liability to the Borrower, any Lender or any other Person for indirect, special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

(d) Change of Address, Etc. Each of the Borrower and the Administrative Agent may change its address, telecopier or telephone number for notices and other communications hereunder by notice to the other parties hereto. Each other Lender may change its address,

telecopier or telephone number for notices and other communications hereunder by notice to the Borrower, and the Administrative Agent. In addition, each Lender agrees to notify the Administrative Agent from time to time to ensure that the Administrative Agent has on record (i) an effective address, contact name, telephone number, telecopier number and electronic mail address to which notices and other communications may be sent and (ii) accurate wire instructions for such Lender.

(e) Reliance by Administrative Agent and Lenders. The Administrative Agent and the Lenders shall be entitled to rely and act upon any notices (including telephonic Loan Notices) purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify the Administrative Agent, each Lender and the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All telephonic notices to and other telephonic communications with the Administrative Agent may be recorded by the Administrative Agent, and each of the parties hereto hereby consents to such recording. Furthermore, each Public-Side Lender agrees to cause at least one individual at or on behalf of such Public-Side Lender to at all times have selected the “PRIVATE-SIDE INFORMATION” or similar designation on the content declaration screen of the Platform in order to enable such Public-Side Lender or its delegate, in accordance with such Public-Side Lender’s compliance procedures and applicable Law, including United States Federal and state securities Laws, to make reference to Borrower Materials that are not made available through the “PUBLIC-SIDE” portion of the Platform and that may contain material non-public information with respect to the Borrower or its securities for purposes of United States Federal or state securities laws.

10.03 No Waiver; Cumulative Remedies. No failure by any Lender or the Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

10.04 Expenses; Indemnity; Damage Waiver.

(a) Costs and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates (including the reasonable fees, charges and disbursements of counsel for the Administrative Agent), in connection with the preparation, negotiation, execution, delivery and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), and (ii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender (including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender), and shall pay all fees and time charges for attorneys who may be employees of the Administrative Agent or any Lender in connection with the enforcement or protection of its

rights (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section, or (B) in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

(b) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), the Lead Arranger, each Co-Arranger and each Lender and each Related Party of each of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower or any other Loan Party arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder, the consummation of the transactions contemplated hereby or thereby, or, in the case of the Administrative Agent (and any sub-agent thereof) and its Related Parties only, the administration of this Agreement and the other Loan Documents, (ii) any Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower or any other Loan Party, and regardless of whether any Indemnitee is a party thereto, in all cases, whether or not caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

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

against the Lead Arranger or any Co-Arranger acting in its capacity as such. The obligations of the Lenders under this subsection (c) are subject to the provisions of Section 2.09(d).

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

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

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

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

10.06 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations

hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section or, (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

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

(B) in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $1,000,000 unless the Administrative Agent otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single assignee (or to an assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met.

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned.

(iii) Required Consents. The consent of the Borrower and the Administrative Agent (each of which such consents not to be unreasonably withheld or delayed) shall be required unless (1) in the case of the Borrower consent only, an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; and provided that the Borrower

shall be deemed to have consented to any assignment if it shall not have responded to any request therefor before 4:00 P.M. (New York City time) three Business Days after the day on which such request was received.

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

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

(vi) No Assignment to Non-Qualified Institutional Buyers or Natural Persons. No such assignment shall be made to (x) a Person that is not a “qualified institutional buyer” within the meaning of Rule 144A or (y) a natural person.

(vii) No Assignment During Syndication. Except pursuant to transactions arranged by the Lead Arranger, no Lender may sell or assign (other than to an Affiliate) any portion of its interest in the Initial Loans until the Syndication Completion Date.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

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

Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent (except as set forth below), sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans 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, (iii) the Borrower, the Administrative Agent 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, (iv) prior to the Syndication Completion Date, no such participation may be granted by any Lender except to an Affiliate of such Lender and (v) no such participation may be granted by any Lender to a Person that is not a “qualified institutional buyer” within the meaning of Rule 144A.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.01 that affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.03 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.01(e) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement 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) Notice to Lead Arranger. The Lead Arranger shall be notified of any participation (except to an Affiliate of the transferor Lender) until the 180^th day after the Closing Date.

10.07 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent, the Lead Arranger, each of the Co-Arrangers and each of the Lenders 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) bona fide or potential assignees, transferees and participants in connection with contemplated assignments, transfers or participations of any Loans or any participations therein or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent, the Lead Arranger, any Co-Arranger or any Lender or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower.

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

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

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

10.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude 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 Article IV, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

10.11 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the

Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Loans, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied.

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

10.13 Replacement of Lenders. If (i) any Lender requests compensation under Section 3.04 or (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, or (iii) any Lender is unwilling to approve an amendment hereto which has been approved by Required Lenders but requires approval of such Lender to be effective, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.06), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

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

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

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

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

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

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

10.14 Governing Law; Jurisdiction; Etc.

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

(b) SUBMISSION TO JURISDICTION. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE ADMINISTRATIVE AGENT OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

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

(d) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 10.02. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

10.15 Waiver of Jury Trial.

EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT

100

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

10.16 No Advisory or Fiduciary Responsibility.

In connection with all aspects of each transaction contemplated hereby, the Borrower acknowledges and agrees that: (i) the credit facility provided for hereunder and any related arranging or other services in connection therewith (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document) are an arm’s-length commercial transaction between the Borrower and its Affiliates, on the one hand, and the Administrative Agent, the Lead Arranger and the Co-Arrangers, on the other hand, and the Borrower is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents (including any amendment, waiver or other modification hereof or thereof); (ii) in connection with the process leading to such transaction, each of the Administrative Agent, the Lead Arranger and each of the Co-Arrangers is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary, for the Borrower or any of its Affiliates, stockholders, creditors or employees or any other Person; (iii) none of the Administrative Agent, the Lead Arranger or any Co-Arranger has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Borrower with respect to any of the transactions contemplated hereby or the process leading thereto, including with respect to any amendment, waiver or other modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent, the Lead Arranger or any Co-Arranger has advised or is currently advising the Borrower or any of its Affiliates on other matters) and none of the Administrative Agent, the Lead Arranger or any Co-Arranger has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; (iv) the Administrative Agent, the Lead Arranger, each of the Co-Arrangers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and none of the Administrative Agent, the Lead Arranger or any Co-Arranger has any obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Administrative Agent, the Lead Arranger and the Co-Arrangers have not provided and will not provide any legal, accounting, regulatory or tax advice with respect to any of the transactions contemplated hereby (including any amendment, waiver or other modification hereof or of any other Loan Document) and the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate. The Borrower hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Administrative Agent, the Lead Arranger or any Co-Arranger with respect to any breach or alleged breach of agency or fiduciary duty.

101

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

The Lenders and the Administrative Agent are herein called the “Guaranteed Parties”.

NOW, THEREFORE, in consideration of the premises and in order to induce the Guaranteed Parties to enter into, and to make Loans under, the Credit Agreement, each Guarantor, jointly and severally with each other Guarantor, agrees as follows:

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

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

hereunder. To effectuate the foregoing intention, the Administrative Agent, the other Guaranteed Parties and the Guarantors irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor and any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Section 4(b) below, will result in the Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance. For purposes hereof, “Bankruptcy Law” means law with respect to any proceeding of the type referred to in Section 8.01(h) of the Credit Agreement or Title 11, U.S. Code, or any similar foreign, federal or state law for the relief of debtors.

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

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

(a) any lack of validity or enforceability of any Loan Document or any agreement or instrument relating thereto;

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

(c) any taking, release or amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Guaranteed Obligations;

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

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

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

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

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

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

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

(i) any defense arising by reason of any claim or defense based upon an election of remedies by any Guaranteed Party that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Guarantor or other rights of such Guarantor to proceed against any of the other Loan Parties, any other guarantor or any other Person, and

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

(d) Each Guarantor unconditionally and irrevocably waives any duty on the part of any Guaranteed Party to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects

of any other Loan Party or any of its Subsidiaries now or hereafter known by such Guaranteed Party.

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

Section 4. Subrogation; Contribution.

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

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

(ii) the irrevocable termination or expiration in whole of all Commitments,

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

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

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

(z) all Commitments shall have been irrevocably terminated or shall have irrevocably expired in whole,

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

(b) Each Guarantor (a “Contributing Guarantor”) agrees that, in the event a payment shall be made by any other Guarantor (a “Claiming Guarantor”) hereunder in respect of any Guaranteed Obligation, the Contributing Guarantor shall indemnify the Claiming Guarantor in an amount equal to the amount of such payment multiplied by a fraction of which the numerator shall be the net assets of such Contributing Guarantor on the date of such payment and the denominator shall be the aggregate net assets of all the Guarantors on the date of such payment, in each case as determined in accordance with GAAP.

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

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

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

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

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a guarantor to a Governmental Authority, such Guarantor shall deliver to the

Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

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

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

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

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

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

(g) If any Guaranteed Party determines that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by a Guarantor or with respect to which a Guarantor has paid additional amounts pursuant to this Section, it shall pay to such

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

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

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

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

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

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

(b) Upon the execution and delivery by any Person of a guaranty supplement in substantially the form of Exhibit A hereto (each, a “Guaranty Supplement”), (i) such Person shall be referred to as an “Additional Guarantor” and shall become and be a Guarantor hereunder, and each reference in this Guaranty to a “Guarantor” shall also mean and be a reference to such Additional Guarantor, and each reference in any other Loan Document to a “Subsidiary Guarantor” shall also mean and be a reference to such Additional Guarantor, and

(ii) each reference herein to “this Guaranty”, “hereunder”, “hereof” or words of like import referring to this Guaranty, and each reference in any other Loan Document to the “Guaranty”, “thereunder”, “thereof” or words of like import referring to this Guaranty, shall mean and be a reference to this Guaranty as supplemented by such Guaranty Supplement and all other Guaranty Supplements.

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

Section 10. No Waiver; Remedies. No failure on the part of any Guaranteed Party to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

Section 11. Right of Set-off. To secure the repayment of the Guaranteed Obligations, each Guarantor grants to each Guaranteed Party, and each of their respective Affiliates, a security interest, a lien, and a right of offset, each of which shall be in addition to all other interests, liens, and rights of any Guaranteed Party, at common Law, under the Loan Documents or otherwise, and each of which shall be upon and against:

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

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

(c) any other credits and claims of Borrower at any time existing against any Guaranteed Party, including claims under certificates of deposit.

At any time and from time to time after the occurrence of any Event of Default, each Guaranteed Party is authorized to foreclose upon, or to offset against the Guaranteed Obligations then due and payable (in either case without notice to such Guarantor), any and all items hereinabove referred to, irrespective of whether or not such Guaranteed Party shall have made any demand under this Guaranty, any other Loan Document and although such obligations

of such Guarantor may be contingent or unmatured or are owed to a branch or office of such Guaranteed Party different from the branch or office holding such items. The remedies of foreclosure and offset are separate and cumulative, and either may be exercised independently of the other without regard to procedures or restrictions applicable to the other.

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

(a) Except during the continuance of an Event of Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), each Guarantor may receive regularly scheduled payments from any other Loan Party on account of the Subordinated Obligations. After the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), however, unless the Administrative Agent otherwise agrees, no Guarantor shall demand, accept or take any action to collect any payment on account of the Subordinated Obligations.

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

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

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

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

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

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

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

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

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

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

Section 14. Execution in Counterparts. This Guaranty and each amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Guaranty by telecopier shall be effective as delivery of an original executed counterpart of this Guaranty.

Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” Unless the context requires otherwise:
