ARTICLE II

THE CREDIT

2.1 Amounts and Terms of the Loans.

(a) Amounts and Terms of the Original Loans.

(i) Subject to the terms and conditions set forth in the Existing Term Loan Agreement, each Lender made term loans (together with any conversions or continuations thereof, the "Original Loans") to the Company on the Effective Date in an aggregate amount of $80,000,000. Principal amounts paid on account of the Original Loans may not be reborrowed.

(ii) The Commitment of each Lender with respect to the Original Loans was permanently reduced to zero on the Effective Date. Such Commitment reductions were made for the account of the Lenders pro rata in accordance with their respective Pro Rata Shares.

(b) Amounts and Terms of the Additional Loans.

(i) Each Lender severally agrees, on the terms and conditions set forth herein, to make additional term loans to the Company on the Restatement Effective Date (together with any conversions or continuations thereof, "Additional Loans" and, together with the Original Loans, "Loans"), so long as, as of the time at which the requested Additional Loan is to be made and after giving effect thereto, (i) the aggregate amount of all Additional Loans by such Lender at such time does not exceed such Lender's Pro Rata Share of the aggregate amount of Additional Loans of all Lenders at such time, and (ii) the aggregate amount of such Lender's Additional Loans does not exceed such Lender's Commitment with respect to the Additional Loans. Principal amounts paid on account of the Additional Loans may not be reborrowed.

(ii) Upon the making of the Additional Loans on the Restatement Effective Date, the Commitment of each Lender with respect to the Additional Loans shall be permanently reduced to zero. Such Commitment reductions shall be made for the account of the Lenders pro rata in accordance with their respective Pro Rata Shares.

(iii) Provided the applicable conditions in Section 5.3 are met, each Lender will make the amount of its Pro Rata Share of the Additional Loans available to the Administrative Agent for the account of the Company at the Agent's Payment Office by 12:00 p.m. (Chicago, Illinois time) on the Restatement Effective Date in funds immediately available to the Administrative Agent. The proceeds of all such Additional Loans will then be made available to the Company by the Administrative Agent by wire transfer to the account(s) specified by the Company in the Notice of Borrowing with respect to the Additional Loans.

(c) The Company agrees that upon the request to the Administrative Agent by any Lender, the Company will promptly execute and deliver to such Lender a promissory note of the Company evidencing the Loans of such Lender, substantially in the form of Exhibit "F" (a "Note"), with appropriate insertions as to date and principal amount; provided, however, that delivery of Notes shall not be a condition precedent to the occurrence of the Restatement Effective Date or the making of the Additional Loans on the Restatement Effective Date. The amount of principal owing on any Lender's Note, if any, at any given time shall be the aggregate amount of all Loans theretofore made by such Lender minus all payments of principal theretofore received by such Lender on such Note. Interest on each Note shall accrue and be due and payable as provided herein and therein.

2.2 Maturity Date. The Loans of each Lender shall mature on the Maturity Date.

2.3 Conversion and Continuation Elections.

(a) Prior to the Termination Date, the Company may, upon irrevocable written notice to the Administrative Agent in accordance with Section 2.3(b) (i) elect, as of any Business Day in the case of Base Rate Loans, or as of the last day of the applicable Interest Period in the case of LIBO Rate Loans, to convert any such Loans into Loans of any other Interest Rate Type; or (ii) elect as of the last day of the applicable Interest Period, to continue any Loans having Interest Periods expiring on such day; provided, however, that if at any time a LIBO Rate Loan is reduced, by payment, prepayment, or conversion of part thereof to less than $1,000,000, such LIBO Rate Loan shall automatically convert into a Base Rate Loan.

(b) The Company shall deliver a Notice of Conversion/Continuation to be received by the Administrative Agent not later than 11:00 a.m. (Chicago, Illinois time) (i) at least three Business Days in advance of the Conversion/Continuation Date, if the Loans are to be converted into or continued as LIBO Rate Loans; and (ii) on the Conversion/Continuation Date, if the Loans are to be converted into Base Rate Loans, specifying: (A) the proposed Conversion/Continuation Date; (B) the aggregate amount of Loans to be converted or continued; (C) the Interest Rate Type of Loans resulting from the proposed conversion or continuation; and (D) other than in the case of conversions into Base Rate Loans, the duration of the requested Interest Period.

(c) If, upon the expiration of any Interest Period applicable to LIBO Rate Loans, the Company has failed to select in a timely manner a new Interest Period to be applicable to LIBO Rate Loans, or if any Default or Event of Default then exists, the Company shall be deemed to have elected to convert such LIBO Rate Loans into Base Rate Loans effective as of the expiration date of such Interest Period.

(d) The Administrative Agent will promptly notify each Lender of its receipt of a Notice of Conversion/Continuation, or, if no timely notice is provided by the Company, the Administrative Agent will promptly notify each Lender of the details of any automatic

conversion. All conversions and continuations shall be made ratably according to the respective Lender's Pro Rata Share of outstanding principal amounts of the Loans with respect to which the notice was given.

(e) The number of tranches outstanding of LIBO Rate Loans, whether under a conversion or continuation, shall not exceed eight (8) at any one time.

2.4 Optional Prepayments.

(a) Subject to Section 3.4, the Company may, at any time or from time to time, subject to the concurrent payment of the Premium:

(i) prepay Base Rate Loans upon irrevocable notice to the Administrative Agent not fewer than one (1) Business Day prior to such prepayment, ratably as to each Lender, in whole or in part, in aggregate minimum principal amounts of $100,000 or integral multiples thereof (unless the Effective Amount is less than $100,000, in which case such prepayments shall be equal to the aggregate unpaid principal amount of the Loans) plus all interest and expenses then outstanding on such Base Rate Loans, and

(ii) prepay LIBO Rate Loans upon irrevocable notice to the Administrative Agent not fewer than three (3) Business Days prior to such prepayment, ratably as to each Lender, in whole or in part, in aggregate minimum principal amounts of $500,000 or integral multiples thereof (unless the Effective Amount is less than $500,000, in which case such prepayments shall be equal to the aggregate unpaid principal amount of the Loans), plus all interest and expenses then outstanding on such LIBO Rate Loans.

Notwithstanding the forgoing, no payment shall be made pursuant to this Section 2.4 if (x) after giving effect to such payment, such payment would cause the Utilization Percentage to exceed 75% or (y) an Event of Default (as defined in the First Lien Credit Agreement) has occurred and is continuing under the First Lien Credit Agreement.

Such notice of prepayment shall specify the date and amount of such prepayment and the Interest Rate Type(s) of Loans to be prepaid. Notwithstanding anything to the contrary set forth in this Section 2.4, any notice of prepayment delivered by the Company may state that such notice is conditioned upon the effectiveness of other financing arrangements, in which case such notice may be revoked by the Company if such condition is not satisfied, but subject to the Company's reimbursement obligations pursuant to Section 3.4 with respect to any funding losses incurred by any Lender as a result of such revocation.

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

(b) For purposes hereof, the "Premium" shall be a cash amount equal to the percentages of principal amount of the Loans being prepaid set forth below:

If prepaid after the Restatement Effective Date, but prior to the first anniversary of the Restatement Effective Date	1.0%

If prepaid on or after the first anniversary of the Restatement Effective Date	0.0%

2.5 [Intentionally omitted.].

2.6 Repayment.

(a) The Company shall repay to the Administrative Agent for the benefit of the Lenders the outstanding principal balance of the Loans (and the outstanding principal of the Loans shall be due and payable) on the Maturity Date or on such date on which the Loans become due and payable pursuant to Section 2.4 or Article IX.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing Indebtedness of the Company to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(c) The Administrative Agent, on behalf of the Company, shall maintain the Register, and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Loan made hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable from the Company to each Lender hereunder and (iii) both the amount of any sum received by the Administrative Agent hereunder from the Company and each Lender's share thereof. The Register shall be available for inspection by each Loan Party, the Administrative Agent and any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) The entries made in the Register and the accounts of each Lender maintained pursuant to Section 2.6(b) shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Company therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of the Company to repay (with applicable interest) the Loans made to the Company by such Lender in accordance with the terms of this Agreement or the Company's entitlement to credit for any payment of principal or interest on the Loans.

2.7 Interest.

(a) (i) Each Original Loan shall bear interest on the principal amount thereof from the Effective Date or date of conversion or continuation pursuant to Section 2.3 of this Agreement, as the case may be, and (ii) each Additional Loan shall bear interest on the principal amount thereof from the Restatement Effective Date or date of conversion or continuation pursuant to Section 2.3 of this Agreement, as the case may be, at a rate per annum equal to the lesser of (x) the LIBO Rate or the Adjusted Base Rate, as the case may be, plus the Applicable Margin and (y) the Highest Lawful Rate.

(b) Interest on each Loan shall be paid in arrears on each Interest Payment Date. Interest shall also be paid on the date of any prepayment of Loans under Section 2.4 for the portion of the Loans so prepaid and upon payment (including prepayment) in full thereof and, during the existence of any Event of Default, interest shall be paid on demand of the Administrative Agent.

(c) Notwithstanding paragraph (a) of this Section 2.7, while any Event of Default under Section 9.1(a) or (b) exists or after acceleration, the Company shall pay interest (after as well as before entry of judgment thereon to the extent permitted by law) on the principal amount of all outstanding Loans, at a rate per annum equal to the lesser of (i) the Highest Lawful Rate and (ii) the rate otherwise applicable plus two percent (2%) ("Default Rate").

2.8 Fees. The Company has paid or will pay (as applicable) fees to the parties and in the amounts specified in the Fee Letter Agreement and the Commitment Letter.

2.9 Computation of Fees and Interest.

(a) All computations of interest for Base Rate Loans shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more interest being paid than if computed on the basis of a 365 day year). Interest and fees shall accrue during each period during which interest or such fees are computed from the first day thereof to the last day thereof.

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

2.10 Payments by the Company; Loan Pro Rata.

(a) All payments to be made by the Company shall be made without set off, recoupment or counterclaim. Except as otherwise expressly provided herein, all payments by the Company shall be made to the Administrative Agent for the account of the Lenders at the Agent's Payment Office, and shall be made in dollars and in immediately available funds, no later than 12:00 p.m. (Chicago, Illinois time) on the date specified herein. Except to the extent otherwise expressly provided herein, (i) each payment by the Company of fees shall be made for the account of the Lenders pro rata in accordance with their respective Pro Rata Shares, (ii) each payment of principal of Loans shall be made for the account of the Lenders pro rata in accordance with their respective outstanding principal amount of such Loans, and (iii) each payment of interest on Loans shall be made for the account of the Lenders pro rata in accordance with their respective shares of the aggregate amount of interest due and payable to the Lenders. The Administrative Agent will promptly distribute to each Lender its applicable share of such payment in like funds as received. Any payment received by the Administrative Agent later than 12:00 p.m. (Chicago, Illinois time) shall be deemed to have been received on the following Business Day and any applicable interest or fee shall continue to accrue.

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

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

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

(e) Notwithstanding anything to the contrary contained herein, after the occurrence and during the continuance of any Event of Default, each payment in respect of principal or interest on the Loans, each payment in respect of fees payable hereunder and any proceeds of Collateral, and Net Cash Proceeds received by the Administrative Agent and not required to be turned over to the First Lien Credit Agent pursuant to the Intercreditor Agreement shall be applied in the following order:

(i) first, to the payment or reimbursement of the Administrative Agent for all costs, expenses, disbursements and losses incurred by the Administrative Agent and which the Company is required to pay or reimburse pursuant to the Loan Documents;

(ii) second, to the payment or reimbursement of the Lenders for all costs, expenses, disbursements and losses incurred by such Persons and which any Loan Party is required to pay or reimburse pursuant to the Loan Documents;

(iii) third, to the payment or prepayment to the Lenders of all Obligations; and

(iv) fourth, to whomsoever shall be legally entitled thereto.

If any Lender owes payments to the Administrative Agent hereunder, any amounts otherwise distributable under this Section 2.10(e) to such Lender shall be deemed to belong to the Administrative Agent to the extent of such unpaid payments, and the Administrative Agent shall apply such amounts to make such unpaid payments rather than distribute such amounts to such Lender. All distributions of amounts described in paragraphs second and third above shall be made by the Administrative Agent to each Lender based on its Pro Rata Share.

2.11 Payments by the Lenders to the Administrative Agent.

(a) Unless the Administrative Agent receives notice from a Lender on or prior to 12:00 pm (Chicago, Illinois time) on the Restatement Effective Date that such Lender will not make available as and when required hereunder to the Administrative Agent for the account of the Company the amount of that Lender's Pro Rata Share of the Additional Loans, the Administrative Agent may assume that each Lender has made such amount available to the Administrative Agent in immediately available funds on the Restatement Effective Date and the Administrative Agent may (but shall not be so required), in reliance upon such assumption, make available to the Company on such date a corresponding amount. If and to the extent any Lender shall not have made its full amount available to the Administrative Agent in immediately available funds and the Administrative Agent in such circumstances has made available to the Company such amount, that Lender shall on the Business Day following the Restatement Effective Date make such amount available to the Administrative Agent, together with interest at the Federal Funds Rate for each day during such period. A notice of the Administrative Agent submitted to any Lender with respect to amounts owing under this Section 2.11(a) shall be conclusive, absent manifest error. If such amount is so made available, such payment to the Administrative Agent shall constitute such Lender's Additional Loan on the Restatement Effective Date for all purposes of this Agreement. If such amount is not made available to the Administrative Agent on the Business Day following the Restatement Effective Date, the Administrative Agent will notify the Company of such failure to fund and, upon demand by the Administrative Agent, the Company shall pay such amount to the Administrative Agent for the Administrative Agent's account, together with interest thereon for each day elapsed since the Restatement Effective Date, at a rate per annum equal to the interest rate applicable at the time to the Loans.

(b) The failure of any Lender to make any Additional Loan on the Restatement Effective Date shall not relieve any other Lender of any obligation hereunder to make an Additional Loan on the Restatement Effective Date, but no Lender shall be responsible for the failure of any other Lender to make the Additional Loan to be made by such other Lender on the Restatement Effective Date.

2.12 Sharing of Payments, Etc. If any Lender shall obtain on account of the Obligations held by it any payment (whether voluntary, involuntary, through the exercise of any right of set off, or otherwise) or receive any collateral in respect thereof in excess of the amount such Lender was entitled to receive pursuant to the terms hereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment according to the terms hereof; provided, however, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender's ratable share (according to the proportion of (i) the amount of such paying Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Company agrees that any Lender so purchasing a participation from another

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

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

3.1 Taxes.

(a) Except as otherwise provided in Section 3.1(c) and Section 10.10, any and all payments by the Company to each Lender or the Administrative Agent under this Agreement and any other Loan Document shall be made free and clear of, and without deduction or withholding for any Taxes. In addition, the Company shall pay all Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(b) Subject to Section 3.1(f), the Company agrees to indemnify and hold harmless each Lender and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 3.1) paid by the Lender or the Administrative Agent and any penalties, interest, additions to Tax and reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Payment under this indemnification shall be made within 30 days after the date the affected Lender or the Administrative Agent makes written demand therefor with reasonable detail as to the particular imposition; provided, however, that neither the Administrative Agent nor any Lender shall be entitled to receive any payment with respect to Taxes or Other Taxes that are incurred or accrued more than 180 days prior to the date the Administrative Agent or Lender (as the case may be) gives notice and demand thereof to the Company.

(c) If the Company shall be required by law to deduct or withhold any Taxes or Other Taxes from or in respect of any amount payable hereunder to any Lender or the Administrative Agent, then: (i) the sum payable shall be increased as necessary so that after making all required deductions and withholdings (including deductions and withholdings applicable to additional sums payable under this Section 3.1), such Lender or the Administrative Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions or withholdings been made; (ii) the Company shall make such deductions and withholdings; and (iii) the Company shall pay the full amount deducted or withheld to the relevant taxing authority or other authority in accordance with applicable law.

(d) As soon as practicable after the date of any payment by the Company of Taxes or Other Taxes under Section 3.1(c) above, the Company shall furnish the Administrative Agent the original or a certified copy of any receipt issued by such taxing

authority or other authority evidencing payment thereof, a copy of any return reporting such payment or other evidence of such payment as the Administrative Agent may reasonably request.

(e) Each Lender shall use its reasonable efforts (consistent with legal and regulatory restrictions) to select a jurisdiction for its Lending Office or change the jurisdiction of its Lending Office so as to avoid the imposition of any Taxes or Other Taxes, or to eliminate or reduce any additional payment under this Section 3.1 or to avoid the obligation to deduct or withhold for taxes under Section 10.10 by the Company if such selection or change in the judgment of such Lender is not materially disadvantageous to such Lender.

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

(g) If the Administrative Agent or a Lender determines that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Company or with respect to which the Company has paid additional amounts pursuant to this Section 3.1, it shall pay over such refund to the Company (but only to the extent of indemnity payments made, or additional amounts paid, by the Company under this Section 3.1 with respect to the Taxes or Other Taxes giving rise to such refund), without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, however, that the Company, upon the reasonable request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Company (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.

3.2 Illegality.

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

(b) If a Lender determines that it is unlawful to maintain any LIBO Rate Loan, the Company shall, upon its receipt of notice of such fact and demand from such Lender (with a copy to the Administrative Agent), prepay in full such LIBO Rate Loans of that Lender then outstanding, together with interest accrued thereon and amounts required under Section 3.4, either on the last day of the Interest Period

thereof, if the Lender may lawfully continue to maintain such LIBO Rate Loans to such day, or immediately, if the Lender may not lawfully continue to maintain such LIBO Rate Loan. If the Company is required to so prepay any LIBO Rate Loan, then concurrently with such prepayment, the Company shall borrow from the affected Lender, in the amount of such repayment, a Base Rate Loan.

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

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

3.3 Increased Costs and Reduction of Return.

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

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

3.4 Funding Losses. The Company shall reimburse each Lender and hold each Lender harmless from any loss or expense which such

Lender may sustain or incur as a consequence of (a) the failure of the Company to make on a timely basis any payment of principal of any LIBO Rate Loan; (b) the failure of the Company to continue a LIBO Rate Loan or to convert a Base Rate Loan to a LIBO Rate Loan after the Company has given (or is deemed to have given) a Notice of Conversion/Continuation (including by reason of the failure to satisfy any condition precedent thereto); (c) the failure of the Company to make any prepayment in accordance with any notice delivered under Section 2.4 (whether pursuant to a permitted revocation of notice of prepayment or otherwise); (d) the prepayment (including pursuant to Section 2.4) or other payment (including after acceleration thereof) of a LIBO Rate Loan on a day that is not the last day of the relevant Interest Period; or (e) the automatic conversion under Section 2.3 of any LIBO Rate Loan to a Base Rate Loan on a day that is not the last day of the relevant Interest Period; including any such loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain its LIBO Rate Loans or from fees payable to terminate the deposits from which such funds were obtained. For purposes of calculating amounts payable by the Company to the Lenders under this Section 3.4 and under Section 3.3(a), each LIBO Rate Loan made by a Lender (and each related reserve, special deposit or similar requirement) shall be conclusively deemed to have been funded at the LIBOR used in determining the LIBO Rate for such LIBO Rate Loan by a matching deposit or other borrowing in the interbank eurodollar market for a comparable amount and for a comparable period, whether or not such LIBO Rate Loan is in fact so funded.

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

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

3.7 Substitution of Lenders. Upon (i) the receipt by the Company from any Lender of a claim for compensation under this Article III, (ii) the refusal of any Lender to execute any amendment, waiver or consent requiring the consent of all Lenders or all affected Lenders as to which Required Lenders have otherwise agreed or (iii) the occurrence and during the continuation of default by a Lender with respect to funding its

Commitment (such Lender, an "Affected Lender"), the Company may (a) obtain a replacement bank or financial institution reasonably satisfactory to the Administrative Agent to acquire and assume all or a ratable part of all of such Affected Lender's Loans (a "Replacement Lender"), or (b) request one more of the other Lenders to acquire and assume all or part of such Affected Lender's Loans, but none of the Lenders shall have any obligation to do so; provided, however, that (x) in the case of clauses (a) and (b), the Company or such assignee shall have paid to the Affected Lender in immediately available funds an amount equal to the sum of the principal of and interest accrued to the date of such payment on the outstanding Loans of such Affected Lender plus all fees and other amounts accrued for the account of such Affected Lender with respect thereto (including any amounts under Section 3.4) and (y) in the case of clause (a), the Company shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld or delayed.

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

ARTICLE IV

SECURITY

4.1 The Security. The Obligations will be and continue to be secured by the Security Documents.

4.3 Perfection and Protection of Security Interests and Liens. The Company shall, and shall cause the Guarantors to, from time to time deliver to the Administrative Agent any financing statements, amendment, assignment and continuation statements, extension agreements and other documents, properly completed and executed (and acknowledged when required) by the Company or a Guarantor, as applicable, in form and substance

reasonably satisfactory to the Administrative Agent, which the Administrative Agent reasonably requests for the purpose of perfecting, confirming, or protecting any Liens or other rights in Collateral securing any Obligations.

4.4 Offset. To secure the repayment of the Obligations, and subject to Section 2.2 of the Security Agreement, the Company hereby grants the Administrative Agent and each Lender 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 the Administrative Agent and the Lenders 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 the Company now or hereafter held or received by or in transit to the Administrative Agent or any Lender from or for the account of the Company, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of the Company with the Administrative Agent or any Lender, and (c) any other credits and claims of the Company at any time existing against the Administrative Agent or any Lender, including claims under certificates of deposit. Each Lender agrees to notify the Company and the Administrative Agent promptly after any such offset and application made by such Lender. During the existence of any Event of Default, the Administrative Agent or any Lender is hereby authorized to foreclose upon, offset, appropriate, and apply, at any time and from time to time, without notice to the Company, any and all items hereinabove referred to against the Obligations then due and payable.

4.5 Guaranty.

(a) Each Guarantor has executed and delivered to the Administrative Agent, and each Subsidiary of the Company created, acquired or coming into existence after the Restatement Effective Date that is required under Section 7.12 to become a Guarantor shall execute and deliver to the Administrative Agent, a Guaranty setting forth therein an absolute and unconditional guaranty of the timely repayment of, and the due and punctual performance of the Obligations of the Company hereunder. The Company will cause each such Subsidiary to deliver to the Administrative Agent, simultaneously with its delivery of such a Guaranty, written evidence reasonably satisfactory to the Administrative Agent and its counsel that such Subsidiary has taken all corporate, limited liability company or partnership action necessary to duly approve and authorize its execution, delivery and performance of such Guaranty and any Security Documents and other documents which it is required to execute.

(b) Guaranty Representations. To induce the Lenders and the Administrative Agent to enter into this Agreement, the Company and each Guarantor represents and warrants to each such Person, (i) in the case of the Original Guarantors, as of and after giving effect to the making of the Original Loans at the Effective Time, and as of and after giving effect to the making of the Additional Loans at the Restatement Effective Time, and (ii) in the case of OPEX after giving effect to the Output Acquisition and the making of the Original Loans at the Output Closing Time, as of the Output Closing Time, and as of and after giving effect to the making of the Additional Loans at the Restatement Effective Time:

(i) Benefit to Guarantors. The board of directors, manager or general partner, where applicable, of each Guarantor has determined that such Guarantor's execution, delivery and performance of this Agreement may reasonably be expected to directly or indirectly benefit such Guarantor and is in the best interests of such Guarantor.

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

(iii) No Insolvencies. Neither the Company nor any Guarantor is "insolvent" (that is, the sum of such Person's absolute and contingent liabilities, including the Obligations, does not exceed the fair value of such Person's assets, including any rights of contribution, reimbursement or indemnity). Each of the Company and each Guarantor has capital which is not unreasonably small for the businesses in which such Person is engaged and intends to be engaged. None of the Company nor any Guarantor has incurred (whether hereby or otherwise), nor does the Company or Guarantor intend to incur or believe that it will incur, liabilities which will be beyond its ability to pay as such liabilities mature.

4.6 Maximum Liability. If and to the extent required in order for the obligations of any Guarantor to be enforceable under applicable federal, state and other laws relating to the insolvency of debtors, the maximum liability of such Guarantor hereunder shall be limited to the greatest amount which can lawfully be guaranteed by such Guarantor under such laws, after giving effect to any rights of contribution, reimbursement and subrogation arising under the Guaranty.

4.7 Production Proceeds. Notwithstanding that, by the terms of the various Security Documents, the Company and the Guarantors are and will be assigning to the Administrative Agent all of the Net Proceeds of Production accruing to the Mortgaged Properties covered thereby, so long as no Event of Default has occurred and is continuing, the Administrative Agent, on behalf of the Lenders, grants each of the Company and the Guarantors a revocable license to continue to receive from the purchasers of production all such Net Proceeds of Production, subject, however, to the Liens created under the Security Documents, which Liens are hereby affirmed and ratified. During the continuance of an Event of Default described under Sections 9.1(g) or (h), this license shall be automatically revoked, and during the continuance of any other Event of Default, this license shall be revocable in the sole discretion of the Administrative Agent, by notice to the Company, and the Administrative Agent may exercise all rights and remedies granted under the Security Documents, including the right to obtain possession of all Net Proceeds of Production then held by the Company and the Guarantors or to receive directly from the purchasers of production all other Net Proceeds of Production. In no case shall any failure, whether purposeful or inadvertent, by the Administrative Agent to collect directly any such Net Proceeds of Production constitute in any way a waiver, remission or release of any of its rights under the Security Documents, nor shall any release of any Net Proceeds of Production by the Administrative

Agent to the Company and the Guarantors constitute a waiver, remission, or release of any other Net Proceeds of Production or of any rights of the Administrative Agent to collect other Net Proceeds of Production thereafter.

Each Lender hereby irrevocably (subject to Section 10.9) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. The duties of the Administrative Agent shall be administrative and mechanical in nature; notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Loan Document, the Administrative Agent shall not have any duty or responsibility, except those expressly set forth herein, nor shall the Administrative Agent, under any circumstances, have or be deemed to have any fiduciary relationship with any Person, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent.

10.2 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, employees or attorneys in fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney in fact that it selects with reasonable care.

10.3 Liability of Administrative Agent. None of the Administrative Agent-Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Lenders for any recital, statement, representation or warranty made by the Company, any Guarantor or any Subsidiary or Affiliate of the Company, or any officer thereof, contained in this Agreement or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness (other than such Administrative Agent-Related Person's own due execution and delivery), genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for any failure of the Company, any Guarantor or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Administrative Agent-Related Person shall be under any obligation to any Lender to ascertain or to inquire as to the observance or

performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the Property, books or records of the Company, any Guarantor or any of the Company's other Subsidiaries or Affiliates.

10.4 Reliance by Administrative Agent.

(a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex, telephonic or electronic message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Lenders and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Lenders.

(b) For purposes of determining compliance with the conditions specified in Article V, each Lender that has made available to the Administrative Agent its Pro Rata Share of the initial Credit Extension or subsequent Credit Extension, as the case may be, shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to the Lender as a condition precedent to such initial Credit Extension or subsequent Credit Extension, as applicable.

10.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, except with respect to Defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Company referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". The Administrative Agent will notify the Lenders of its receipt of any such notice. Subject to Section 10.4(a), the Administrative Agent shall take such action with respect to such Default or Event of Default as may be requested by the Required Lenders in accordance with Article IX; provided, however, that unless and until the Administrative Agent has received any such request, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interest of the Lenders.

10.6 Credit Decision. Each Lender acknowledges that no Administrative Agent-Related Person has made any representation or warranty to it, and that no act by any Administrative Agent-Related Person hereafter taken, including any review of the affairs of the Company, any

Guarantor or their respective Subsidiaries, shall be deemed to constitute any representation or warranty by any Administrative Agent-Related Person to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Administrative Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, Property, financial and other condition and creditworthiness of the Company, and all applicable bank regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Company hereunder. Each Lender also represents that it will, independently and without reliance upon any Administrative Agent-Related Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, Property, financial and other condition and creditworthiness of the Company. Except for notices, reports and other documents expressly herein required to be furnished to the Lenders by the Administrative Agent, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, Property, financial and other condition or creditworthiness of the Company which may come into the possession of any of the Administrative Agent-Related Persons.

10.7 Indemnification. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand the Administrative Agent-Related Persons (to the extent not reimbursed by or on behalf of the Company and without limiting the obligation of the Company to do so), pro rata according to each respective Lender's Pro Rata Share, each Administrative Agent-Related Person from and against any and all Indemnified Liabilities INCLUDING SUCH INDEMNIFIED LIABILITIES AS MAY ARISE OR BE CAUSED BY THE NEGLIGENCE, SOLE, JOINT, CONCURRENT, COMPARATIVE OR OTHERWISE OF SUCH ADMINISTRATIVE AGENT-RELATED PERSONS; provided, however, that no Lender shall be liable for the payment to any Administrative Agent-Related Persons of any portion of such Indemnified Liabilities to the extent the same arise from (i) the gross negligence or willful misconduct of any Administrative Agent-Related Person or (ii) a claim or action asserted by one or more other Administrative Agent-Related Persons. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out of pocket expenses (including Attorney Costs) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Transaction Document or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Company. The undertaking in this Section 10.7 shall survive the payment of all Obligations hereunder and the resignation or replacement of the Administrative Agent.

10.8 Administrative Agent in Individual Capacity. Bank of Montreal and its Affiliates may make loans to, accept deposits from, acquire or underwrite equity or debt securities of and generally engage in any kind of banking, investment banking, trust, financial advisory, underwriting or other business with the Company and its Affiliates as though Bank of Montreal were not the Administrative Agent hereunder and without notice to or

consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Bank of Montreal or its Affiliates may receive information regarding the Company or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Company or such Affiliate) and acknowledge that the Administrative Agent-Related Persons shall be under no obligation to provide such information to them. With respect to Obligations held by it, Bank of Montreal shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent.

10.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 30 days' notice to the Lenders. If the Administrative Agent resigns under this Agreement, the Lenders shall appoint from among the Lenders a successor administrative agent for the Lenders, which successor agent shall be consented to by the Company (which consent shall not be unreasonably withheld or delayed). If no successor administrative agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Lenders and the Company, a successor administrative agent from among the Lenders. Upon the acceptance of its appointment as successor administrative agent hereunder, such successor administrative agent shall succeed to all the rights, powers and duties of the retiring Administrative Agent and the term "Administrative Agent" shall mean such successor administrative agent and the retiring Administrative Agent's appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent's resignation hereunder as Administrative Agent, the provisions of this Article X and Sections 11.4 and 11.5 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agent's notice of resignation, the retiring Administrative Agent's resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Lenders appoint a successor administrative agent as provided for above.

10.10 Withholding Tax.

(a) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the laws of the United States, or under any treaty to which the United States is a party, with respect to payments under this Agreement shall deliver to the Company (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Company or the Administrative Agent 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 Company or the Administrative Agent, shall deliver such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Company or the Administrative Agent as will enable the Company or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Each Lender shall promptly (i) notify the Company and the Administrative Agent of any change in circumstances which would modify or render invalid any such claimed

exemption or reduction and (ii) take such steps as may be required pursuant to Section 3.1(e).

(b) Without limiting the generality of the foregoing provisions of Section 10.10(a), each Foreign Lender shall deliver to the Company 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 Company 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 IRS 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 IRS 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 Company 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 IRS 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 Company or the Administrative Agent to determine the withholding or deduction required to be made.

(c) If any Lender delivers to the Company and the Administrative Agent completed and executed documentation described in Section 10.10(a) and (b) claiming a reduction in withholding tax, the Company and the Administrative Agent may withhold from any amount payable to such Lender hereunder an amount equivalent to the applicable withholding tax after taking into account such reduction. If the forms or other documentation required by Section 10.10(a) and (b) are not delivered by a Lender to the Company and the Administrative Agent, then the Company and the Administrative Agent may withhold from any amount payable to such Lender not providing such forms or other documentation an amount equivalent to the applicable withholding tax.

(d) If the IRS or any other Governmental Authority of the United States or other jurisdiction asserts a claim that the Company or the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly completed or executed, or because such Lender failed to notify the Company and the Administrative Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective or modified, or for any other reason) such Lender shall indemnify the Company and the Administrative Agent fully for all amounts paid, directly or indirectly, by the

Company or the Administrative Agent (as the case may be) as tax or otherwise, including penalties, additions to tax and interest, and including any taxes imposed by any jurisdiction on the amounts payable to the Company or the Administrative Agent under this Section 10.10(d), together with all costs and expenses (including Attorney Costs). The obligation of the Lenders under this Section 10.10(d) shall survive the payment of all Obligations and the resignation or the replacement of the Administrative Agent.

10.11 Arranger; Syndication Agent. Each of the Arranger and the Syndication Agent, in their respective capacities as such, shall have no duties or responsibilities, and shall incur no liability, under this Agreement or the other Loan Documents.

10.12 Release of Collateral. The Administrative Agent is hereby irrevocably authorized by each of the Lenders to effect any release of Liens or Guaranty Obligations contemplated by Section 11.26.

(c) reduce the principal of, or the rate of interest specified herein on any Loan, or (subject to clause (ii) below) any fees or other amounts payable hereunder (it being understood that a change to the definition of "Default Rate" or the waiver of an Event of Default shall not constitute a reduction of the principal of or rate of interest specified) or under any other Loan Document;

(d) change the pro rata application of payments, prepayments, reductions of the Commitments or change in any manner the definition of "Required Lenders";

(e) amend this Section 11.1, or any provision of this Agreement which, by its terms, expressly requires the approval or concurrence of all Lenders; or

provided further, however, that no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Required Lenders or all the Lenders, as the case may be, affect the rights or duties of the Administrative Agent under this Agreement or any other Loan Document.

The Administrative Agent and the Lenders shall be entitled to rely on the authority of any Person purporting to be a Person authorized by the Company to give such notice and the Administrative Agent and the Lenders shall not have any liability to the Company or any other Person on account of any action taken or not taken by the Administrative Agent or the Lenders in reliance upon such telephonic or facsimile notice. The obligation of the Company to repay the Loans shall not be affected in any way or to any extent by any failure by the Administrative Agent and the Lenders to receive written confirmation of any telephonic or facsimile notice or the receipt by the Administrative Agent and the Lenders of a confirmation which is at variance with the terms understood by the Administrative Agent and the Lenders to be contained in the telephonic or facsimile notice.

11.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, 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.

11.4 Costs and Expenses. The Company shall:

(a) whether or not the transactions contemplated hereby are consummated, pay or reimburse the Administrative Agent and the Arranger within five Business Days after demand for all reasonable and documented out-of-pocket costs and expenses incurred by the Administrative Agent, the Arranger or any of their Affiliates in connection with the syndications of the Credit Extensions hereunder (other than fees payable to syndicate members) and the development, preparation, delivery, administration and execution of, and any amendment, supplement, waiver or modification to (in each case, whether or not consummated), this Agreement, any Loan Document and any other documents prepared in connection herewith or therewith, the consummation of the transactions contemplated hereby and thereby, and the syndication of the credit facilities provided herein, including Attorney Costs incurred by such Person with respect thereto except such costs and expenses as may be incurred by the assignor Lenders or Assignee under Section 11.8; and

No Indemnified Person shall be liable for any damages arising from the use by unauthorized Persons of information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such Persons or for any special, indirect, consequential or punitive damages in connection with this Agreement. All amounts due under this Section 11.5 shall be payable not later than 30 days after written demand therefor. The agreements in Section 11.4 and this Section 11.5 shall survive payment of all other Obligations.

11.6 Payments Set Aside. To the extent that the Company makes a payment to the Administrative Agent or the Lenders, or the Administrative Agent or the Lenders exercise their right of set-off, and such payment or the proceeds of such set-off or any part thereof are 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, debtor-in-possession, receiver or any other Person, in connection with any Insolvency Proceeding 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 set-off had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent or such Lender upon demand its Pro Rata Share of any amount so recovered from or repaid by the Administrative Agent or such Lender.

11.7 Successors and Assigns. This Agreement shall become effective at the Restatement Effective Time after it shall have been executed by the Company, each Guarantor and the Administrative Agent and after the Administrative Agent shall have been notified by each Lender that such Lender has executed it and thereafter this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, except that the Company may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent and each Lender.

11.8 Assignments, Participations, etc.

(a) Each Lender may assign to one or more assignees (each, an "Assignee") all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent of the Administrative Agent (not to be unreasonably withheld or delayed) and prior written notice to (but not consent of) the Company; provided, however, that (i) the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance in the form of Exhibit "E" (the "Assignment and Acceptance") with respect to such assignment is delivered to the Administrative Agent and determined on an aggregate basis in the event of concurrent assignments to Related Funds (as defined below)) shall not, unless consented to by the Administrative Agent, be less than $1,000,000 (or, if less, the entire remaining amount of such Lender's Commitment or Loans), (ii) the parties to each such assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance via an electronic settlement system acceptable to the Administrative Agent (or, if previously agreed with the Administrative Agent, manually) and shall pay to the Administrative Agent a processing and recordation fee in the amount of $3,500.00 (which fee may be waived or reduced in the sole discretion of the Administrative Agent), provided further, however, that only one such fee shall be payable in the case of concurrent assignments to Persons that, after giving effect to such assignments, will be Related Funds and (iii) the Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire in such form as supplied from time to time by the Administrative Agent (an "Administrative Questionnaire") and all applicable tax forms. Upon acceptance and recording pursuant to Section 11.8(c), from and after the effective date specified in each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an 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 Article III and Section 11.5, as well as to any fees accrued for its account prior to the effective date specified in such Assignment and Acceptance and not yet paid). The term "Related Funds" shall mean with respect to any Lender that is a fund or combined investment vehicle that invests in bank loans, any other fund that invests in bank loans and is managed or advised by the same investment advisor as such Lender or by an Affiliate of such investment advisor.

(b) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the Assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment, and the outstanding balances of its Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance, (ii) except as set forth in (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of the Company or any Subsidiary or the performance or observance by the Company or any Subsidiary of any of its obligations under this Agreement, any other Loan Document or any other

instrument or document furnished pursuant hereto; (iii) such Assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance; (iv) such Assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in Section 6.14 or delivered pursuant to Section 7.1, the Intercreditor Agreement and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (v) such Assignee will independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such Assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement, as are delegated to the Administrative Agent, by the terms hereof and thereof, together with such powers as are reasonably incidental thereto; and (vii) such Assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender and will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreement. The Administrative Agent shall be entitled to rely, without any independent investigation, on the representations and warranties and other statements deemed to be made by the assigning Lender and the Assignee pursuant to this Section 11.8(c) and shall not incur any liability for relying thereon.

(c) The Administrative Agent, acting for this purpose as an agent of the Company, shall maintain at one of its offices in Chicago, Illinois a copy of each Assignment and Acceptance delivered to it. Upon its receipt of, and consent to, a duly completed Assignment and Acceptance executed by an assigning Lender and an Assignee, an Administrative Questionnaire completed in respect of the Assignee (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 11.8(b) above, if applicable, and the written consent of the Administrative Agent to such assignment and any applicable tax forms, the Administrative Agent shall (i) accept such Assignment and Acceptance and (ii) record the information contained therein in the Register. No assignment shall be effective unless it has been recorded in the Register as provided in this Section 11.8(c). The Register shall be available for inspection by the Company or any Lender (with respect to any entry relating to such Lender's Loans) at any reasonable time and from time to time upon reasonable prior notice.

(d) Notwithstanding anything to the contrary contained herein, any Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC"), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Company, the option to provide to the Company all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Company on the Restatement Effective Date pursuant to this Agreement; provided, however, that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an

SPC hereunder shall utilize theCommitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior Indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 11.8, any SPC may (i) with notice to, but without the prior written consent of, the Company and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non−public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC.

(e) Within five Business Days after its receipt of notice by the Administrative Agent that it has received an executed Assignment and Acceptance and payment of the processing fee, if a Note was issued in respect of the assigned interests, upon the request of the Administrative Agent by the Assignee, the Company shall execute and deliver to the Administrative Agent a new Note evidencing such Assignee's assigned Loans and, if the assignor Lender has retained a portion of its Loans and its Commitment, a replacement Note, upon the request of the Administrative Agent by the assignor Lender, in the principal amount equal to the Loans and Commitments, if any, retained by the assignor Lender (such Note to be in exchange for, but not in payment of, the Note held by such Lender).

(f) Any Lender may at any time sell to one or more commercial banks or other Persons not Affiliates of the Company (a "Participant") participating interests in any Loans, the Commitment of that Lender, if any, and the other interests of that Lender (the "Originating Lender") hereunder and under the other Loan Documents; provided, however, that (i) the Originating Lender's obligations under this Agreement shall remain unchanged, the Originating Lender shall remain a Lender for all purposes hereof and the other Loan Documents to which such Originating Lender is a party, and the Participant may not become a Lender for purposes hereof or for any other of the Loan Documents, (ii) the Originating Lender shall remain solely responsible for the performance of such obligations, (iii) the Company and the Administrative Agent shall continue to deal solely and directly with the Originating Lender in connection with the Originating Lender's rights and obligations under this Agreement and the other Loan Documents, and (iv) no Lender shall transfer or grant any participating interest under which the Participant has rights to approve any amendment to, or any consent or waiver with respect to, this Agreement or any other Loan Document, except to the extent such amendment, consent or waiver would require unanimous consent of the Lenders. In the case of any such participation, the Participant shall not have any rights under this Agreement, or any of the other Loan Documents (the

Participant's rights against the Originating Lender in respect of such participation being those set forth in the agreement creating or evidencing such participation with such Lender), and all amounts payable by the Company hereunder shall be determined as if such Lender had not sold such participation; except that, if amounts outstanding under this Agreement are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence and continuance of an Event of Default, each Participant shall be deemed to have the right of set off in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement.

(g) Each Lender agrees to take normal and reasonable precautions and exercise due care to maintain the confidentiality of all information provided to it by the Company, or by the Administrative Agent on the Company's behalf, under or in connection with this Agreement or any other Loan Document, and neither it nor any of its Affiliates shall use any such information other than in connection with or in enforcement of this Agreement and the other Loan Documents, except to the extent such information (i) was or becomes generally available to the public other than as a result of disclosure by such Lender, or (ii) was or becomes available on a non-confidential basis from a source other than the Company, provided, however, that such source is not bound by a confidentiality agreement with the Company known to the Lender; provided further, however, that any Lender may disclose such information (and, in the case of the following subclauses (A) through (D), shall provide promptly written notice of such disclosure to the Company) (A) at the request or pursuant to any requirement of any Governmental Authority to which such Lender is subject or in connection with an examination of such Lender by any such authority; (B) pursuant to subpoena or other court process; (C) when required to do so in accordance with the provisions of any applicable Requirement of Law; (D) to the extent reasonably required in connection with any litigation or proceeding to which the Administrative Agent, any Lender or their respective Affiliates may be party; (E) to the extent reasonably required in connection with the exercise of any remedy hereunder or under any other Loan Document; (F) to such Lender's independent auditors and other professional advisors; (G) to any Affiliate of such Lender, or to any Participant or Assignee, actual or potential, provided that such Affiliate, Participant or Assignee agrees to keep such information confidential to the same extent required of the Lenders hereunder; and (H) as to any Lender, as expressly permitted under the terms of any other document or agreement regarding confidentiality to which the Company is party or is deemed to be party with such Lender.

(h) Notwithstanding any other provision in this Agreement, any Lender may at any time create a security interest in, or pledge, all or any portion of its rights under and interest in this Agreement and the Note held by it in favor of any Federal Reserve Lender in accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR §203.14, and such Federal Reserve Lender may enforce such pledge or security interest in any manner permitted under applicable law. Any Lender may at any time assign all or any portion of its rights under this Agreement to secure extensions of credit to such Lender or in support of obligations owed by such Lender; provided, however,

that no such assignment shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto.

11.9 Interest. It is the intention of the parties hereto to comply with applicable usury laws, if any; accordingly, notwithstanding any provision to the contrary in this Agreement, the Notes or in any of the other Loan Documents securing the payment hereof or otherwise relating hereto, in no event shall this Agreement, the Notes or such other Loan Documents require or permit the payment, taking, reserving, receiving, collection, or charging of any sums constituting interest under applicable laws which exceed the Highest Lawful Rate. If any such excess interest is called for, contracted for, charged, taken, reserved, or received in connection with the Loans evidenced by the Notes or in any of the Loan Documents securing the payment thereof or otherwise relating thereto, or in any communication by the Administrative Agent or the Lenders or any other Person to the Company or any other Person, or in the event all or part of the principal or interest thereof shall be prepaid or accelerated, so that under any of such circumstances or under any other circumstance whatsoever the amount of interest contracted for, charged, taken, reserved, or received on the amount of principal actually outstanding from time to time under the Notes or any other Loan Document shall exceed the Highest Lawful Rate, then in any such event it is agreed as follows: (i) the provisions of this Section 11.9 shall govern and control, (ii) neither any Company nor any other Person now or hereafter liable for the payment of the Notes shall be obligated to pay the amount of such interest to the extent such interest is in excess of the Highest Lawful Rate, (iii) any such excess which is or has been received notwithstanding this Section 11.9 shall be credited against the then unpaid principal balance of the Notes or, if the Notes have been or would be paid in full, refunded to the Company, and (iv) the provisions of this Agreement, the Notes and the other Loan Documents securing the payment thereof and otherwise relating thereto, and any communication to the Company, shall immediately be deemed reformed and such excess interest reduced, without the necessity of executing any other document, to the Highest Lawful Rate as now or hereafter construed by courts having jurisdiction hereof or thereof. Without limiting the foregoing, all calculations of the rate of the interest contracted for, charged, collected, taken, reserved, or received in connection with the Notes, this Agreement or any other Loan Document which are made for the purpose of determining whether such rate exceeds the Highest Lawful Rate shall be made to the extent permitted by applicable laws by amortizing, prorating, allocating and spreading during the period of the full term of the Loans, including all prior and subsequent renewals and extensions, all interest at any time contracted for, charged, taken, collected, reserved, or received. The terms of this Section 11.9 shall be deemed to be incorporated in every document and communication relating to the Notes, the Loans or any other Loan Document.

11.10 Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation as any Guarantor may have under applicable law, the Company agrees that in the event a payment shall be made by a Guarantor under a Guaranty in respect of a Credit Extension to the Company, the Company shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the Person to whom such payment shall have been made to the extent of such payment subject to the provisions of the Guaranty executed by such Guarantor. Notwithstanding any provision of this Agreement to the contrary, all rights of the Guarantors under this Section 11.10 and all other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full of the

Obligations, and no payments may be made in respect of such rights of indemnity, contribution or subrogation until all the Obligations have been paid in full and the Commitments shall have expired. No failure on the part of the Company to make the payments required by this Section 11.10 (or any other payments required under applicable law or otherwise) shall in any respect limit the obligations and liabilities of the Guarantors with respect to any Guaranty, and each Guarantor shall remain liable for the full amount of the obligation of the Guarantors under each such Guaranty in accordance therewith.

11.11 Automatic Debits of Fees. With respect to any fee, or any other cost or expense (including Attorney Costs) due and payable to the Administrative Agent under the Loan Documents, the Company hereby irrevocably authorizes the Administrative Agent, after giving reasonable prior notice to the Company, to debit any deposit account of the Company with the Administrative Agent in an amount such that the aggregate amount debited from all such deposit accounts does not exceed such fee or other cost or expense. If there are insufficient funds in such deposit accounts to cover the amount of the fee or other cost or expense then due, such debits will be reversed (in whole or in part, in the Administrative Agent's sole discretion) and such amount not debited shall be deemed to be unpaid. No such debit under this Section 11.11 shall be deemed a set-off.

11.12 Notification of Addresses, Lending Offices, Etc. Each Lender shall notify the Administrative Agent in writing of any changes in the address to which notices to the Lender should be directed, of addresses of any Lending Office, of payment instructions in respect of all payments to be made to it hereunder and of such other administrative information as the Administrative Agent shall reasonably request.

11.13 Counterparts. This Agreement may be executed in any number of separate counterparts, no one of which need be signed by all parties; each of which, when so executed, shall be deemed an original, and all of such counterparts taken together shall be deemed to constitute but one and the same instrument. A fully executed counterpart of this Agreement by facsimile signatures shall be binding upon the parties hereto.

11.14 Severability. The illegality or unenforceability of any provision of this Agreement or any instrument or agreement required hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement or any instrument or agreement required hereunder.

11.15 No Third Parties Benefited. This Agreement is made and entered into for the sole protection and legal benefit of the Company, the Guarantors, the Lenders, the Administrative Agent, the Administrative Agent-Related Persons and the Indemnified Persons, and their permitted successors and assigns, and no other Person shall be a direct or indirect legal beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement or any of the other Loan Documents.

11.16 Governing Law, Jurisdiction. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

11.17 Submission To Jurisdiction; Waivers. Each of the parties hereto hereby irrevocably and unconditionally:

(a) submits, for itself and its Property, to the nonexclusive jurisdiction of the Supreme Court 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 for recognition or enforcement of any judgment, and each of the parties hereto hereby 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 or, to the extent permitted by 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 shall affect any right that the Administrative Agent may otherwise have to bring any action or proceeding relating to this Agreement against the Company or any Guarantor or its respective Property in the courts of any jurisdiction;

(b) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in Section 11.17(a), and each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court; and

(c) consents to service of process in the manner provided for notices herein; provided, however, nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

11.18 Entire Agreement. This Agreement, together with the other Loan Documents, embodies the entire agreement and understanding among the Company, the Guarantors, the Lenders and the Administrative Agent, and supersedes all prior or contemporaneous agreements and understandings of such Persons, oral or written, relating to the subject matter hereof and thereof.

11.19 NO ORAL AGREEMENTS. THIS AGREEMENT, TOGETHER WITH THE OTHER WRITTEN LOAN DOCUMENTS EXECUTED IN CONNECTION HEREWITH, REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

11.20 Accounting Changes. If at any time any Accounting Change (as defined below) would affect the computation of any financial ratio or requirement set forth in any Loan Document, and either the Company or the Required Lenders shall so request, the Administrative Agent and the Company shall negotiate to amend such ratio or requirement to preserve the original intent thereof in light of such Accounting Change (subject to the approval of the Required Lenders); provided, however, that until so amended such ratio or requirement shall continue to be computed

in accordance with GAAP prior to such change therein. "Accounting Change" refers to any change in accounting principles required by the promulgation of any rule, regulation, pronouncement or opinion by the Financial Accounting Standards Board of the American Institute of Certified Public Accountants or, if applicable, the SEC.

11.21 WAIVER OF JURY TRIAL, PUNITIVE DAMAGES, ETC. THE COMPANY, THE GUARANTORS, THE LENDERS AND THE ADMINISTRATIVE AGENT EACH HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY (A) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY; (B) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY "SPECIAL DAMAGES", AS DEFINED BELOW, (C) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (D) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 11.21. AS USED IN THIS SECTION, "SPECIAL DAMAGES" INCLUDES ALL SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO.

11.22 Intercreditor Agreement. Each Lender (a) hereby agrees that it will be bound by and take no actions contrary to the Intercreditor Agreement and (b) hereby irrevocably authorizes and instructs the Administrative Agent to enter into the Intercreditor Agreement on its behalf.

11.23 USA PATRIOT Act. Each Lender hereby notifies each Loan Party that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), it is required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow such Lender to identify such Loan Party in accordance with that Requirement of Law.

11.24 Acknowledgments. Each of the Company and each Guarantor hereby acknowledges that:

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents;

(b) neither the Administrative Agent, any other Agent nor any Lender has any fiduciary relationship with or duty to the Company or any Guarantor arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Administrative Agent, any other Agent and the Lenders, on one hand, and the Company and the Guarantors, on the other hand, in connection herewith or therewith is solely that of creditor and debtor; and

All representations and warranties made herein, in the other Loan Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Loans and other extensions of credit hereunder.

11.26 Release of Collateral and Guarantee Obligations.

(a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, but subject to Sections 5.1(e) and 5.4 (e) of the Intercreditor Agreement, upon request of the Company in connection with any Disposition of Property (including any Disposition of a Guarantor) permitted by the Loan Documents, the Administrative Agent shall (without notice to, or vote or consent of, any Lender or any Qualified Derivative Contract Counterparty) take such actions as shall be required to release its security interest in any Collateral being Disposed of in such Disposition, and to release any Guaranty Obligations under any Loan Document of any Person being Disposed of in such Disposition, to the extent necessary to permit consummation of such Disposition in accordance with the Loan Documents; provided, however, that the Company shall have delivered to the Administrative Agent, at least ten Business Days prior to the date of the proposed release (or such shorter period agreed to by the Administrative Agent), a written request for release identifying the relevant Collateral being Disposed of in such Disposition and, in the case of a Disposition under Section 8.2(f) or any other Disposition of Collateral comprising (i) Hydrocarbon Interests or (ii) other Property with a book value in excess of $2,000,000, and the terms of such Disposition in reasonable detail, including the date thereof, the price thereof and any expenses in connection therewith, together with a certification by the Company stating that such transaction is in compliance with this Agreement and the other Loan Documents and that the proceeds of such Disposition will be applied in accordance with this Agreement and the other Loan Documents.

(b) Notwithstanding anything to the contrary contained herein or any other Loan Document, when all Obligations have been paid or otherwise satisfied in full and all Commitments have terminated or expired, but subject to Sections 5.1(e) and 5.4(e) of the Intercreditor Agreement, upon request of the Company, the Administrative Agent shall (without notice to, or vote or consent of, any Lender, or any Qualified Derivative Contract Counterparty) take such actions as shall be required to release its security interest in all Collateral, and to release all Guaranty Obligations provided for in any Loan Document; provided, however, that in lieu of terminating and repaying any such

Obligations arising under any Qualified Derivative Contract, the Company may provide substitute credit support under a standard form ISDA Credit Support Annex or other credit support documents reasonably acceptable to such Qualified Derivative Contract Counterparty to cover its then current exposure under such Qualified Derivative Contract and such Qualified Derivative Contract Counterparty shall have provided written notice to the Administrative Agent to the effect that such substitute credit support has been provided to it and that such Qualified Derivative Contract Counterparty no longer claims any right, title or interest in any Collateral arising under the Loan Documents to secure any Obligations and Indebtedness of the Company or any of its Subsidiaries arising under or related to such Qualified Derivative Contract, whether then existing or thereafter arising. Any such release of Guaranty Obligations shall be deemed subject to the provision that such Guaranty Obligations shall be reinstated if after such release any portion of any payment in respect of the Obligations guaranteed thereby shall be rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company or any Guarantor or any substantial part of its Property, or otherwise, all as though such payment had not been made.

11.27 Amendment and Restatement.

(a) From and after the Restatement Effective Time, this Agreement amends and restates in its entirety the Existing Term Loan Agreement; the Existing Term Loan Agreement shall thereafter be of no further force and effect except to evidence (i) the incurrence by the Company of the Existing Obligations (whether or not any such Existing Obligations are contingent as of the Restatement Effective Time), (ii) the representations and warranties made by any Loan Party prior to the Restatement Effective Time and (iii) any act or omission performed or required to be performed pursuant to the Existing Term Loan Agreement prior to the Restatement Effective Time (including any failure, prior to the Restatement Effective Time, to comply with the covenants contained in such Existing Term Loan Agreement). The amendments and restatements set forth herein shall not cure any breach thereof or any "Default" or "Event of Default" under and as defined in the Existing Term Loan Agreement existing prior to the Restatement Effective Time. This Agreement does not constitute and shall not be construed to evidence a novation of or a payment and readvance of any of the Existing Obligations, it being the intention of the parties hereto that this Agreement is an amendment and restatement (but not an extinguishment) of the Existing Term Loan Agreement.

(b) The terms and conditions of this Agreement and the Administrative Agent's and the Lenders' rights and remedies under this Agreement and the other Loan Documents shall apply to all of the Existing Obligations.

(c) Each of the Company and Guarantors reaffirms the Liens granted pursuant to the Security Documents to the Administrative Agent for the benefit of the Secured Parties, which Liens shall continue in full force and effect during the term of this Agreement and any renewals or extensions thereof.

(d) Each of the Guarantors reaffirms the guaranties made pursuant to the Guaranty (or a joinder thereto) in favor of the Administrative Agent for the benefit of the Secured Parties, which guaranties shall continue in full force and effect during the terms of this Agreement and any renewals or extensions thereof as guaranties of the Obligations.

(e) From and after the Restatement Effective Time, except as the context otherwise provides, (i) all references to the Existing Term Loan Agreement (or to any amendment, supplement, modification or amendment and restatement thereof) in the Loan Documents (other than this Agreement) shall be deemed to refer to this Agreement, (ii) all references to any section (or subsection) of the Existing Term Loan Agreement in any Loan Document (but not herein) shall be amended to become mutatis mutandis, references to the corresponding provisions of this Agreement and (iii) all references to this Agreement herein (including for purposes of indemnification and reimbursement of fees) shall be deemed to be references to this Agreement as the same may be further amended, restated, amended and restated, supplemented or otherwise modified from time to time pursuant to the terms of this Agreement and of the Intercreditor Agreement.

(f) This Agreement is limited as written and is not a consent to any other amendment, restatement, waiver or other modification, whether or not similar, and, except as expressly provided herein or in any other Loan Document, all terms and conditions of the Loan Documents remain in full force and effect unless otherwise specifically amended by this Agreement or any other Loan Document.
