If at any time the L/C Obligations exceed such permitted amount, the Borrowers shall furnish to the Administrative Agent cash collateral satisfactory to the Administrative Agent in an amount equal to such excess to be applied in accordance with Section 12.2(b).

(b) Each Letter of Credit shall (i) be denominated in Dollars in a minimum amount of $100,000, (ii) be a standby letter of credit issued to support obligations of the Borrowers or any of their Subsidiaries, contingent or otherwise, incurred in the ordinary course of business, (iii) expire on a date no later than one (1) year from the date of issuance thereof; provided, that in no case shall such expiration date be later than five (5) Business Days prior to the Revolving Credit Maturity Date and (iv) be subject to the Uniform Customs and/or ISPA 98, as set forth in the Application or as determined by the Issuing Lender and to the extent not inconsistent therewith, the laws of the State of New York. The Issuing Lender shall not at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause the Issuing Lender or any L/C Participant to exceed any limits imposed by, any Applicable Law. References herein to "issue" and derivations thereof with respect to Letters of Credit shall also include extensions or modifications of any Existing Letters of Credit, unless the context otherwise requires.

SECTION 3.2 Procedure for Issuance of Letters of Credit. The Borrowers may from time to time request that the Issuing Lender issue a Letter of Credit by delivering to the Issuing Lender at the Administrative Agent's Office an Application therefor, completed to the satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as the Issuing Lender may request. Upon receipt of any Application, the Issuing Lender shall process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall, subject to Section 3.1 and Article VI hereof, promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be

required to issue any Letter of Credit earlier than three (3) Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender and the Borrowers. The Issuing Lender shall promptly furnish to the Borrowers a copy of such Letter of Credit and promptly notify each Lender of the issuance and upon request by any Lender, furnish to such Lender a copy of such Letter of Credit and the amount of such Lender's L/C Participation therein.

(a) The Borrowers shall pay to the Administrative Agent, for the account of the Issuing Lender and the L/C Participants, a letter of credit commission with respect to each Letter of Credit in an amount equal to the product of (i) the face amount of such Letter of Credit times (ii) an annual percentage equal to the Applicable Margin with respect to LIBOR Rate Loans in effect on the date of issuance of such Letter of Credit. Such commission shall be payable quarterly in arrears on the last Business Day of each calendar quarter and on the Revolving Credit Maturity Date.

(b) In addition to the foregoing commission, the Borrowers shall pay the Issuing Lender an issuance fee of 0.125% per annum on the face amount of each Letter of Credit, payable quarterly in arrears on the last Business Day of each calendar quarter and on the Revolving Credit Maturity Date; provided, that such issuance fee shall not be payable with respect to the Existing Letters of Credit.

(c) The Borrowers shall also pay all normal costs and expenses of the Issuing Lender in connection with the issuance, transfer or other administration of the Letters of Credit.

(d) The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Lender and the L/C Participants all commissions received by the Administrative Agent in accordance with their respective Revolving Credit Commitment Percentages.

(a) The Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce the Issuing Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant's own account and risk an undivided interest equal to such L/C Participant's Revolving Credit Commitment Percentage in the Issuing Lender's obligations and rights under each Letter of Credit and the amount of each draft paid by the Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrowers in accordance with the terms of this Agreement, such L/C Participant shall pay to the Issuing Lender upon demand at the Issuing Lender's address for notices specified herein an amount equal to such L/C Participant's Revolving Credit Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed.

(b) Upon becoming aware of any amount required to be paid by any L/C Participant to the Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by the Issuing Lender under any Letter of Credit, the Issuing Lender shall notify each L/C Participant of the amount and due date of such required payment and such L/C Participant shall pay to the Issuing Lender the amount specified on the applicable due date. If any such amount is paid to the Issuing Lender after the date such payment is due, such L/C Participant shall pay to the Issuing Lender on demand, in addition to such amount, the product of (i) such amount, times (ii) the daily average Federal Funds Rate as determined by the Administrative Agent during the period from and including the date such payment is due to the date on which such payment is immediately available to the Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. A certificate of the Issuing Lender with respect to any

amounts owing under this Section 3.4(b) shall be conclusive in the absence of manifest error. With respect to payment to the Issuing Lender of the unreimbursed amounts described in this Section 3.4(b), if the L/C Participants receive notice that any such payment is due (A) prior to 1:00 p.m. (Charlotte time) on any Business Day, such payment shall be due that Business Day, and (B) after 1:00 p.m. (Charlotte time) on any Business Day, such payment shall be due on the following Business Day.

(c) Whenever, at any time after the Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its Revolving Credit Commitment Percentage of such payment in accordance with this Section 3.4, the Issuing Lender receives any payment related to such Letter of Credit (whether directly from any Borrower or otherwise), or any payment of interest on account thereof, the Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, that in the event that any such payment received by the Issuing Lender shall be required to be returned by the Issuing Lender, such L/C Participant shall return to the Issuing Lender the portion thereof previously distributed by the Issuing Lender to it.

SECTION 3.5 Reimbursement Obligation of the Borrowers. In the event of any drawing under any Letter of Credit, the Borrowers jointly and severally agree to reimburse (either with the proceeds of a Revolving Credit Loan as provided for in this Section 3.5 or with funds from other sources), in same day funds, the Issuing Lender on each date on which the Issuing Lender notifies the Borrowers of the date and amount of a draft paid under any Letter of Credit for the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by the Issuing Lender in connection with such payment. Unless the Borrowers shall immediately notify the Issuing Lender that the Borrowers intend to reimburse the Issuing Lender for such drawing from other sources or funds, the Borrowers shall be deemed to have timely given a Notice of Revolving Credit/Swingline Borrowing to the Administrative Agent requesting that the Lenders make a Revolving Credit Loan bearing interest at the Base Rate on such date in the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by the Issuing Lender in connection with such payment, and the Lenders shall make a Revolving Credit Loan bearing interest at the Base Rate in such amount, the proceeds of which shall be applied to reimburse the Issuing Lender for the amount of the related drawing and costs and expenses. Each Lender acknowledges and agrees that its obligation to fund a Revolving Credit Loan in accordance with this Section 3.5 to reimburse the Issuing Lender for any draft paid under a Letter of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Section 2.3(a) or Article VI. If the Borrowers have elected to pay the amount of such drawing with funds from other sources and shall fail to reimburse the Issuing Lender as provided above, the unreimbursed amount of such drawing shall bear interest at the rate which would be payable on any outstanding Base Rate Loans which were then overdue from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full.

SECTION 3.6 Obligations Absolute. The obligations of the Borrowers under this Article III (including without limitation the Reimbursement Obligation) shall be irrevocable, absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which the Borrowers may have or have had against the Issuing Lender or any beneficiary of a Letter of Credit. The Borrowers also agree with the Issuing Lender that the Issuing Lender and the L/C Participants shall not be responsible for, and the Reimbursement Obligation of the Borrowers under Section 3.5 shall not be affected by, among other things, the validity or genuineness of this Agreement, any documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrowers and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of a Borrower against any beneficiary of such Letter of Credit or any such transferee or the application or misapplication of the proceeds or any Letter of Credit by any beneficiary thereunder. The Issuing Lender shall not be liable for any error, omission, interruption or

delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions caused by the Issuing Lender's gross negligence or willful misconduct. The Borrowers agree that any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct and in accordance with the standards of care specified in the Uniform Customs and, to the extent not inconsistent therewith, the UCC as in effect in the State of New York from time to time shall be binding on the Borrowers and shall not result in any liability of the Issuing Lender or any L/C Participant to the Borrowers. The responsibility of the Issuing Lender to the Borrowers in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit.

SECTION 3.7 Effect of Application. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Article III, the provisions of this Article III shall apply.

SECTION 4.1 Term Loans. Subject to the terms and conditions of this Agreement, each Lender severally agrees to make the following Term Loans:

(a) A Term A Loan to the Borrowers on a joint and several basis on the Closing Date in a principal amount equal to such Lender's Term A Loan Commitment; and

(b) A Term B Loan to the Borrowers on a joint and several basis on the Closing Date in a principal amount equal to such Lender's Term B Loan Commitment.

The Borrowers hereby irrevocably authorize the Administrative Agent to disburse the proceeds of each borrowing requested pursuant to this Section 4.2 in immediately available funds by crediting or wiring such proceeds to the deposit account of the Borrowers identified in the Notice of Account Designation.

(c) No Reborrowing of Term Loans. Amounts prepaid under the Term Loans pursuant to Section 4.3 or Section 4.4 may not be reborrowed and will constitute a permanent reduction in the applicable Term Loan Commitment. Each prepayment shall be accompanied by any amount required to be paid pursuant to Section 5.9 hereof.

SECTION 4.5 Term Notes. Each Lender's Term A Loans and the obligation of the Borrowers to repay such Term A Loans shall be evidenced by a Term A Note, payable to the order of such Lender representing the Borrowers' obligation to pay such Lender's Term A Loan Commitment in accordance with the terms hereof. Each Lender's Term B Loans and the obligation of the Borrowers to repay such Term B Loans shall be evidenced by a Term B Note, payable to the order of such Lender representing the Borrowers' obligation to pay such Lender's Term B Loan Commitment in accordance with the terms hereof. Each Term Note shall bear interest on the unpaid principal amount thereof at the applicable interest rate per annum specified in Section 5.1.

(a) Interest Rate Options. Subject to the provisions of this Section 5.1, at the election of the Company on behalf of the Borrowers, the aggregate principal balance of any Revolving Credit Note and any Term Loan Note shall bear interest at (i) the Base Rate plus the Applicable Margin as set forth in Section 5.1(c) or (ii) the LIBOR Rate plus the Applicable Margin as set forth in Section 5.1(c); provided that the LIBOR Rate shall not be available until three (3) Business Days after the Closing Date. The Swingline Note shall bear interest at the Base Rate plus the Applicable Margin as set forth in Section 5.1(c). The Borrowers shall select the rate of interest and Interest Period, if any, applicable to any Loan at the time a Notice of Revolving Credit/Swingline Borrowing is given pursuant to Section 2.3(a) or a Notice of Term Loan Borrowing is given pursuant to Section 4.2 or at the time a Notice of Conversion/Continuation is given pursuant to Section 5.2. Each Loan or portion thereof bearing interest based on the Base Rate (other than Swingline Loans) shall be a "Base Rate Loan", each Loan or portion thereof bearing interest based on the LIBOR Rate shall be a "LIBOR Rate Loan." Any Loan or any portion thereof as to which the Borrowers have not duly specified an interest rate as provided herein shall be deemed a Base Rate Loan.

(b) Interest Periods. In connection with each LIBOR Rate Loan, the Company on behalf of the Borrowers, by giving notice at the times described in Section 5.1(a), shall elect an interest period (each, an "Interest Period") to be applicable to such LIBOR Rate Loan, which Interest Period shall be a period of one (1), two (2), three (3), or six (6) months with respect to each LIBOR Rate Loan; provided that:

(c) Applicable Margin. The Applicable Margin provided for in Section 5.1(a) with respect to the Loans (the "Applicable Margin") shall be based upon the Leverage Ratio as set forth in the table below and shall be determined and adjusted quarterly on the date (each a "Calculation Date") ten (10) Business Days after the date by which the Borrowers are required to provide an Officer's Compliance Certificate for the most recently ended fiscal quarter of the Borrowers and their Subsidiaries; provided, that with respect to the period commencing on the Effective Date and ending on the next Calculation Date to occur after the Effective Date, the calculation of the Applicable Margin shall be based on the most recent Officer's Compliance Certificate received by the Administrative Agent and Lenders prior to the Effective Date. Notwithstanding the foregoing, if the Borrowers fail to provide the Officer's Compliance Certificate as required by Section 8.2 for the most recently ended fiscal quarter of the Borrowers and their Subsidiaries preceding the applicable Calculation Date, the Applicable Margin from such Calculation Date shall be based on Pricing Level 1 (as shown below) until such time as an appropriate Officer's Compliance Certificate is provided, at which time the Pricing Level shall be determined by reference to the Leverage Ratio as of the last day of the most recently ended fiscal quarter of the Borrowers preceding such Calculation Date. The Applicable Margin shall be effective from one Calculation Date until the next Calculation Date. Any adjustment in the Applicable Margin shall be applicable to all Extensions of Credit then existing or subsequently made or issued.

		Revolving Credit and Term A Loan Facilities Applicable Margin Per Annum	Term B Loan Facility Applicable Margin Per Annum
Level	Leverage Ratio	Base Rate +	LIBOR Rate +	Base Rate +	LIBOR Rate +

4	Less than 2.00 to 1.00 but greater than or equal to 1.50 to 1.00.	2.00%	3.00%	2.50%	3.50%
5	Less than 1.50 to 1.00.	1.75%	2.75%	2.25%	3.25%

Notwithstanding the foregoing, the Leverage Ratios set forth in this Section 5.1(c) are for pricing purposes only and shall not be deemed to permit the Leverage Ratio to exceed the maximum amounts permitted under this Agreement. The Applicable Margins set forth in this Section 5.1(c) represent base pricing subject to increase as set forth in Section 5.1(d).

(d) Default Rate. Subject to Section 12.3, at the discretion of the Administrative Agent and Required Lenders upon the occurrence and during the continuance of an Event of Default, (i) the

Borrowers shall no longer have the option to request LIBOR Rate Loans or Swingline Loans, (ii) all outstanding LIBOR Rate Loans shall bear interest at a rate per annum two percent (2%) in excess of the rate then applicable to LIBOR Rate Loans, as applicable, until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate then applicable to Base Rate Loans (calculated at the highest Applicable Margin), and (iii) all outstanding Base Rate Loans and Swingline Loans shall bear interest at a rate per annum equal to two percent (2%) in excess of the rate then applicable to Base Rate Loans. Interest shall continue to accrue on the Notes after the filing by or against any Borrower of any petition seeking any relief in bankruptcy or under any act or law pertaining to insolvency or debtor relief, whether state, federal or foreign.

(e) Interest Payment and Computation. Interest on each Base Rate Loan and Swingline Loans shall be payable in arrears on the last Business Day of each calendar quarter commencing June 30, 2000; and interest on each LIBOR Rate Loan shall be payable on the last day of each Interest Period applicable thereto, and if such Interest Period extends over three (3) months, at the end of each three (3) month interval during such Interest Period. Interest on LIBOR Rate Loans and all fees payable hereunder shall be computed on the basis of a 360-day year and assessed for the actual number of days elapsed and interest on Base Rate Loans shall be computed on the basis of a 365/66-day year and assessed for the actual number of days elapsed.

(f) Maximum Rate. In no contingency or event whatsoever shall the aggregate of all amounts deemed interest hereunder or under any of the Notes charged or collected pursuant to the terms of this Agreement or pursuant to any of the Notes exceed the highest rate permissible under any Applicable Law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. In the event that such a court determines that the Lenders have charged or received interest hereunder in excess of the highest applicable rate, the rate in effect hereunder shall automatically be reduced to the maximum rate permitted by Applicable Law and the Lenders shall at the Administrative Agent's option (i) promptly refund to the Borrowers any interest received by Lenders in excess of the maximum lawful rate or (ii) shall apply such excess to the principal balance of the Obligations. It is the intent hereof that the Borrowers not pay or contract to pay, and that neither the Administrative Agent nor any Lender receive or contract to receive, directly or indirectly in any manner whatsoever, interest in excess of that which may be paid by the Borrowers under Applicable Law.

SECTION 5.2 Notice and Manner of Conversion or Continuation of Loans. Provided that no Event of Default has occurred and is then continuing, the Borrowers shall have the option to convert at any time following the third Business Day after the Closing Date all or any portion of its outstanding Base Rate Loans (other than Swingline Loans) in a principal amount equal to $2,000,000 or any whole multiple of $500,000 in excess thereof into one or more LIBOR Rate Loans and (b) upon the expiration of any Interest Period, (i) convert all or any part of its outstanding LIBOR Rate Loans in a principal amount equal to $1,000,000 or a whole multiple of $250,000 in excess thereof into Base Rate Loans or (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the Borrowers desire to convert or continue Loans as provided above, the Company on behalf of the Borrowers shall give the Administrative Agent irrevocable prior written notice in the form attached as Exhibit F (a "Notice of Conversion/Continuation") not later than 11:00 a.m. (Charlotte time) three (3) Business Days before the day on which a proposed conversion or continuation of such Loan is to be effective specifying (A) the Loans to be converted or continued, and, in the case of any LIBOR Rate Loan to be converted or continued, the last day of the Interest Period therefor specifying the Credit Facility to which such Loan relates, (B) the effective date of such conversion or continuation (which shall be a Business Day), (C) the principal amount of such Loans to be converted or continued, and (D) the Interest Period to be applicable to such converted or continued LIBOR Rate Loan. The Administrative Agent shall promptly notify the Lenders of such Notice of Conversion/Continuation.

(a) Commitment Fee. Commencing on the Closing Date and continuing through but excluding the Revolving Credit Maturity Date, the Borrowers shall pay to the Administrative Agent, for the account of the Lenders, a non-refundable commitment fee at a rate per annum equal to the rate set forth below (the "Commitment Fee Rate") on the average daily unused portion of the Revolving Credit Commitment (the outstanding principal balance of all Revolving Credit Loans, Swingline Loans and L/C Obligations shall be considered usage). The commitment fee shall be payable in arrears on the last Business Day of each calendar quarter commencing June 30, 2000, and on the Revolving Credit Maturity Date. Such commitment fee shall be distributed by the Administrative Agent to the Lenders pro rata in accordance with the Lenders' respective Revolving Credit Commitment Percentages. The Commitment Fee Rate provided for above shall equal the percentage set forth below corresponding to the level at which the Applicable Margin is determined in accordance with Section 5.1(c). Any change in the applicable level at which Applicable Margin is determined shall result in a corresponding and simultaneous change in the Commitment Fee Rate.

Level		Commitment Fee Rate
1		0.500%
2		0.500%
3		0.500%
4		0.375%
5		0.375%

(b) Administrative Agent's and Other Fees. In order to compensate the Administrative Agent for structuring and syndicating the Loans and for its obligations hereunder, the Borrowers agree to pay to the Administrative Agent, for its account, the fees set forth in the separate fee letter agreement executed by the Company, on behalf of itself and the other Borrowers, and the Administrative Agent dated March 29, 2000.

SECTION 5.4 Manner of Payment. (a) Each payment by the Borrowers on account of the principal of or interest on the Revolving Credit Loans or of any fee, commission or other amounts (including the Reimbursement Obligation) payable to the Lenders under this Agreement with respect to the Revolving Credit Loans, the Letters of Credit or any Revolving Credit Note shall be made not later than 1:00 p.m. (Charlotte time) on the date specified for payment under this Agreement to the Administrative Agent at the Administrative Agent's Office for the account of the Lenders having a Revolving Credit Commitment (other than as set forth below) pro rata in accordance with their respective Revolving Credit Commitment Percentages, (except as specified below) in Dollars, in immediately available funds and shall be made without any set-off, counterclaim or deduction whatsoever, (b) each payment to the Administrative Agent on account of the principal of or interest on the Swingline Loans or of any fee, commission or other amounts shall be made in like manner, except for the account of the Swingline Lender, (c) each payment by the Borrowers on account of the principal of or interest on the Term A Loans or of any fee, commission or other amounts payable to the Lenders under this Agreement with respect to the Term A Loans or any Term A Note shall be made in like manner, for the account of the Lenders having a Term A Loan Commitment pro rata in accordance with their respective Term A Loan Percentages and shall be made without any set-off, counterclaim or deduction whatsoever, (d) each payment by the Borrowers on account of the principal of or interest on the Term B Loans or of any fee, commission or other amounts payable to the Lenders under this Agreement with respect to the Term B Loans or any Term B Note shall be made in like manner, for the account of the Lenders having a Term B Loan Commitment pro rata in accordance with their respective Term B Loan Percentages and shall be made without any set-off, counterclaim or

deduction whatsoever and (e) any other amounts payable to the Lenders under this Agreement shall be made in like manner pro rata based on its or their respective share in the Obligation with respect to which such payment was received and shall be made without any set-off, counterclaim or deduction whatsoever. Any payment received after such time but before 2:00 p.m. (Charlotte time) on such day shall be deemed a payment on such date for the purposes of Section 12.1, but for all other purposes shall be deemed to have been made on the next succeeding Business Day. Any payment received after 3:00 p.m. (Charlotte time) shall be deemed to have been made on the next succeeding Business Day for all purposes. Upon receipt by the Administrative Agent of each such payment, the Administrative Agent shall distribute to each Lender at its address for notices set forth herein its pro rata share of such payment in accordance with such Lender's Revolving Credit Commitment Percentage, Term A Loan Percentage and/or Term B Loan Percentage, as applicable (except as specified below) and shall wire advice of the amount of such credit to each Lender. Each payment to the Administrative Agent of the Issuing Lender's fees or L/C Participants' commissions shall be made in like manner, but for the account of the Issuing Lender or the L/C Participant, as the case may be. Each payment to the Administrative Agent of the Administrative Agent's or Issuing Lender's fees or expenses shall be made for the account of the Administrative Agent or Issuing Lender, as the case may be, and each amount payable by the Borrowers to the Swingline Lender with respect to the Swingline Note shall be made to the Administrative Agent for the account of the Swingline Lender, and any amount payable to any Lender under Sections 5.8, 5.9, 5.10, 5.11 or 14.2 shall be paid to the Administrative Agent for the account of the applicable Lender. Subject to Section 5.1(b)(ii) if any payment under this Agreement or any Note shall be specified to be made upon a day which is not a Business Day, it shall be made on the next succeeding day which is a Business Day and such extension of time shall in such case be included in computing any interest if payable along with such payment.

SECTION 5.5 Crediting of Payments and Proceeds. In the event that the Borrowers shall fail to pay any of the Obligations when due and the Obligations have been accelerated pursuant to Section 12.2, all payments received by the Lenders upon the Notes and the other Obligations and all net proceeds from the enforcement of the Obligations shall be applied first to all expenses then due and payable by the Borrowers hereunder, then to all indemnity obligations then due and payable by the Borrowers hereunder, then to all Administrative Agent's and Issuing Lender's fees then due and payable, then to all commitment and other fees and commissions then due and payable, then to accrued and unpaid interest on the Swingline Note to the Swingline Lender, then to the principal amount outstanding under the Swingline Note to the Swingline Lender, then to accrued and unpaid interest on the other Notes and the Reimbursement Obligation (pro rata in accordance with all such amounts due), then to the principal amount of the other Notes and Reimbursement Obligation and any termination payments due in respect of a Hedging Agreement with any Lender (which such Hedging Agreement is permitted hereunder and required or requested by the Required Lenders) (pro rata in accordance with all such amounts due) and then to the cash collateral account described in Section 12.2(b) hereof to the extent of any L/C Obligations then outstanding, then to any termination payments due in respect of a Hedging Agreement with any Lender (which such Hedging Agreement is permitted, but not required or requested by the Required Lenders), in that order.

SECTION 5.6 Adjustments. If any Lender (a "Benefited Lender") shall at any time receive any payment of all or part of the Obligations owing to it, or interest thereon, or if any Lender shall at any time receive any collateral in respect of the Obligations owing to it (whether voluntarily or involuntarily, by set-off or otherwise) in a greater proportion than any such payment to and collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, or interest thereon, such Benefited Lender shall purchase for cash from the other Lenders such portion of each such other Lender's Extensions of Credit, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, that if all or any portion of such excess payment or benefits is thereafter recovered from such

Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned to the extent of such recovery, but without interest. The Borrowers agree that each Lender so purchasing a portion of another Lender's Extensions of Credit may exercise all rights of payment (including, without limitation, rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion.

SECTION 5.7 Nature of Obligations of Lenders Regarding Extensions of Credit; Assumption by the Administrative Agent. The obligations of the Lenders under this Agreement to make the Loans and issue or participate in Letters of Credit are several and are not joint or joint and several. Unless the Administrative Agent shall have received notice from a Lender prior to a proposed borrowing date that such Lender will not make available to the Administrative Agent such Lender's ratable portion of the amount to be borrowed on such date (which notice shall not release such Lender of its obligations hereunder), the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the proposed borrowing date in accordance with Sections 2.3(b) and 4.2, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers on such date a corresponding amount. If such amount is made available to the Administrative Agent on a date after such borrowing date, such Lender shall pay to the Administrative Agent on demand an amount, until paid, equal to the product of (a) the amount not made available by such Lender in accordance with the terms hereof, times (b) the daily average Federal Funds Rate during such period as determined by the Administrative Agent, times (c) a fraction the numerator of which is the number of days that elapse from and including such borrowing date to the date on which such amount not made available by such Lender in accordance with the terms hereof shall have become immediately available to the Administrative Agent and the denominator of which is 360. A certificate of the Administrative Agent with respect to any amounts owing under this Section 5.7 shall be conclusive, absent manifest error. If such Lender's Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of such borrowing is not made available to the Administrative Agent by such Lender within three (3) Business Days after such borrowing date, the Administrative Agent shall be entitled to recover such amount made available by the Administrative Agent with interest thereon at the rate per annum applicable to Base Rate Loans hereunder, on demand, from the Borrowers. The failure of any Lender to make its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of any Loan available shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of such Loan available on such borrowing date, but no Lender shall be responsible for the failure of any other Lender to make its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of such Loan available on the borrowing date.

(a) Circumstances Affecting LIBOR Rate Availability. If with respect to any Interest Period the Administrative Agent or any Lender (after consultation with Administrative Agent) shall determine that, by reason of circumstances affecting the foreign exchange and interbank markets generally, deposits in eurodollars, in the applicable amounts are not being quoted via Dow Jones Market Screen 3750 or offered to the Administrative Agent or such Lender for such Interest Period, then the Administrative Agent shall forthwith give notice thereof to the Borrowers. Thereafter, until the Administrative Agent notifies the Borrowers that such circumstances no longer exist, the obligation of the Lenders to make LIBOR Rate Loans and the right of the Borrowers to convert any Loan to or continue any Loan as a LIBOR Rate Loan shall be suspended, and the Borrowers shall repay in full (or cause to be repaid in full) the then outstanding principal amount of each such LIBOR Rate Loan together with accrued interest thereon, on the last day of the then current Interest Period applicable to such LIBOR Rate Loan or convert the then outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan as of the last day of such Interest Period.

(b) Laws Affecting LIBOR Rate Availability. If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Offices) to honor its obligations hereunder to make or maintain any LIBOR Rate Loan, such Lender shall promptly give notice thereof to the Administrative Agent and the Administrative Agent shall promptly give notice to the Borrowers and the other Lenders. Thereafter, until the Administrative Agent notifies the Borrowers that such circumstances no longer exist, (i) the obligations of the Lenders to make LIBOR Rate Loans and the right of the Borrowers to convert any Loan or continue any Loan as a LIBOR Rate Loan shall be suspended and thereafter the Borrowers may select only Base Rate Loans hereunder, and (ii) if any of the Lenders may not lawfully continue to maintain a LIBOR Rate Loan to the end of the then current Interest Period applicable thereto as a LIBOR Rate Loan, the applicable LIBOR Rate Loan shall immediately be converted to a Base Rate Loan for the remainder of such Interest Period.

(c) Increased Costs. If, after the date hereof, the introduction of, or any change in, any Applicable Law, or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of such Governmental Authority, central bank or comparable agency:

SECTION 5.9 Indemnity. The Borrowers hereby indemnify each of the Lenders against any loss or expense which may arise or be attributable to each Lender's obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any Loan (a) as a consequence of any failure by the Borrowers to make any payment when due of any amount due hereunder in connection with a LIBOR Rate Loan, (b) due to any failure of the Borrowers to borrow on a date specified therefor in a Notice of Borrowing or Notice of Continuation/Conversion or make a prepayment after giving notice thereof to the Administrative Agent or (c) due to any payment, prepayment or conversion of any LIBOR Rate Loan on a date other than the last day of the Interest Period therefor. The amount of such loss or expense shall be determined, in the applicable Lender's sole discretion, based upon the assumption that such Lender funded its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as applicable, of the LIBOR Rate Loans in the London interbank market and using any reasonable attribution or averaging methods which such Lender deems appropriate and practical. A certificate of such Lender setting forth the basis for determining such amount or amounts necessary to compensate such Lender shall be forwarded to the Borrowers through the Administrative Agent and shall be conclusively presumed to be correct save for manifest error.

SECTION 5.10 Capital Requirements. If after the date hereof either (a) the introduction of, or any change in, or in the interpretation of, any Applicable Law or (b) compliance with any guideline or request from any central bank or comparable agency or other Governmental Authority (whether or not having the force of law), has or would have the effect of reducing the rate of return on the capital of, or has affected or would affect the amount of capital required to be maintained by, any Lender or any corporation controlling such Lender as a consequence of, or with reference to the Commitments and other commitments of this type, below the rate which the Lender or such other corporation could have achieved but for such introduction, change or compliance, then within five (5) Business Days after written demand by any such Lender, the Borrowers shall pay to such Lender from time to time as specified by such Lender additional amounts sufficient to compensate such Lender or other corporation for such reduction. A certificate as to such amounts submitted to the Borrowers and the Administrative Agent by such Lender, shall, in the absence of manifest error, be presumed to be correct and binding for all purposes.

(a) Payments Free and Clear. Any and all payments by the Borrowers hereunder or under the Notes or the Letters of Credit shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholding, and all liabilities with respect thereto excluding, (i) in the case of each Lender and the Administrative Agent, income and franchise taxes imposed by the jurisdiction under the laws of which such Lender or the Administrative Agent (as the case may be) is organized or is or should be qualified to do business or any political subdivision thereof, (ii) in the case of each Lender, income and franchise taxes imposed by the jurisdiction of such Lender's Lending Office or any political subdivision thereof and (iii) any United States federal income tax that is imposed on, or required to be deducted from, a payment hereunder (or under the Notes or Letters of Credit) by reason of a failure to comply with the requirements of Section 5.11(e) (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrowers shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder or under any Note or Letter of Credit to any Lender or the Administrative Agent, (A) the sum payable shall be increased as may be

necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional sums payable under this Section 5.11) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the amount such party would have received had no such deductions or withholdings been made, (B) the Borrowers shall make such deductions or withholdings, (C) the Borrowers shall pay the full amount deducted to the relevant taxing authority or other authority in accordance with applicable law, and (D) the Borrowers shall deliver to the Administrative Agent evidence of such payment to the relevant taxing authority or other Governmental Authority in the manner provided in Section 5.11(d).

(b) Stamp and Other Taxes. In addition, the Borrowers shall pay any present or future stamp, registration, recordation or documentary taxes or any other similar fees or charges or excise or property taxes, levies of the United States or any state or political subdivision thereof or any applicable foreign jurisdiction which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Loans, the Letters of Credit, the other Loan Documents, or the perfection of any rights or security interest in respect thereto (hereinafter referred to as "Other Taxes").

(c) Indemnity. The Borrowers shall indemnify each Lender and the Administrative Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this Section 5.11) paid by such Lender or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Such indemnification shall be made within thirty (30) days from the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor.

(d) Evidence of Payment. Within thirty (30) days after the date of any payment of Taxes or Other Taxes, the Borrowers shall furnish to the Administrative Agent, at its address referred to in Section 14.1, the original or a certified copy of a receipt evidencing payment thereof or other evidence of payment satisfactory to the Administrative Agent.

(e) Delivery of Tax Forms. Each Lender organized under the laws of a jurisdiction other than the United States or any state thereof shall deliver to the Borrowers, with a copy to the Administrative Agent, on the Closing Date or concurrently with the delivery of the relevant Assignment and Acceptance, as applicable, (i) two United States Internal Revenue Service Forms W-8ECI or Forms W-8BEN, as applicable (or successor forms) properly completed and certifying in each case that such Lender is entitled to a complete exemption from withholding or deduction for or on account of any United States federal income taxes, and (ii) an Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable form, as the case may be, to establish an exemption from United States backup withholding taxes. Each such Lender further agrees to deliver to the Borrowers, with a copy to the Administrative Agent, a Form W-8BEN or W-8ECI, or successor applicable forms or manner of certification, as the case may be, on or before the date that any such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrowers, certifying in the case of a Form W-8BEN or W-8ECI that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes (unless in any such case an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders such forms inapplicable or the exemption to which such forms relate unavailable and such Lender notifies the Borrowers and the Administrative Agent that it is not entitled to receive payments without deduction or withholding of United States federal income taxes) and, in the case of a Form W-8BEN or W-8ECI, establishing an exemption from United States backup withholding tax.

(f) Survival. Without prejudice to the survival of any other agreement of the Borrowers hereunder, the agreements and obligations of the Borrowers contained in this Section 5.11 shall survive the payment in full of the Obligations and the termination of the Commitments.

SECTION 5.12 Security. The Obligations of the Borrowers shall be secured as provided in the Security Documents.

SECTION 6.1 Closing. The closing shall take place at the offices of Kennedy Covington Lobdell & Hickman at 10:00 a.m. on February 28, 2003, or on such other date and time as the parties hereto shall mutually agree.

SECTION 6.2 Conditions to Closing. Each of the conditions to closing set forth in the Fourth Amendment shall have been satisfied on or prior to the Effective Date.

SECTION 6.3 Conditions to All Extensions of Credit. The obligations of the Lenders to make any Extensions of Credit are subject to the satisfaction of the following conditions precedent on the date of such Extension of Credit:

(a) Continuation of Representations and Warranties. The representations and warranties contained in Article VII shall be true and correct on and as of such borrowing or issuance date with the same effect as if made on and as of such date; except for any representation and warranty made as of an earlier date, which representation and warranty shall remain true and correct as of such earlier date.

(b) No Existing Default. No Default or Event of Default shall have occurred and be continuing hereunder (i) on the borrowing date with respect to such Loan or after giving effect to the Loans to be made on such date or (ii) or the issue date with respect to such Letter of Credit or after giving effect to the issuance of such Letter of Credit on such date.

(c) Officer's Compliance Certificate; Additional Documents. The Administrative Agent shall have received the current Officer's Compliance Certificate and each additional document, instrument, legal opinion or other item of information reasonably requested by it.

SECTION 7.1 Representations and Warranties. To induce the Administrative Agent and Lenders to enter into this Agreement and to induce the Lenders to make Extensions of Credit, each Borrower hereby represents and warrants to the Administrative Agent and Lenders both before and after giving effect to the transactions contemplated hereunder that:

(a) Organization; Power; Qualification. Each Borrower and each Subsidiary thereof is duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation, has the power and authority to own its properties and to carry on its business as now being and hereafter proposed to be conducted and is duly qualified and authorized to do business in each jurisdiction in which the character of its properties or the nature of its business requires such qualification and authorization, except where the failure to be duly qualified and authorized will not have a Material Adverse Effect. The jurisdictions in which each Borrower and each Subsidiary thereof are organized and qualified to do business as of the Closing Date are described on Schedule 7.1(a).

(b) Ownership. Each Subsidiary of each Borrower as of the Closing Date is listed on Schedule 7.1(b). As of the Closing Date, the capitalization of each Borrower and each Subsidiary thereof consists

of the number of shares, authorized, issued and outstanding, of such classes and series, with or without par value, described on Schedule 7.1(b). All outstanding shares have been duly authorized and validly issued and are fully paid and nonassessable. The shareholders of the Subsidiaries of each Borrower and the number of shares owned by each as of the Closing Date are described on Schedule 7.1(b). As of the Closing Date, there are no outstanding stock purchase warrants, subscriptions, options, securities, instruments or other rights of any type or nature whatsoever, which are convertible into, exchangeable for or otherwise provide for or permit the issuance of capital stock of any Borrower or any Subsidiary thereof, except as described on Schedule 7.1(b).

(c) Authorization of Agreement, Loan Documents and Borrowing. Each Borrower and each Subsidiary thereof has the right, power and authority and has taken all necessary corporate and other action to authorize the execution, delivery and performance of this Agreement and each of the other Loan Documents to which it is a party in accordance with their respective terms. This Agreement and each of the other Loan Documents have been duly executed and delivered by the duly authorized officers of each Borrower and each of its Subsidiaries party thereto, and each such document constitutes the legal, valid and binding obligation of each Borrower or its Subsidiary party thereto, enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar state or federal debtor relief laws from time to time in effect which affect the enforcement of creditors' rights in general and the availability of equitable remedies.

(d) Compliance of Agreement, Loan Documents and Borrowing with Laws, Etc. The execution, delivery and performance by each Borrower and each Subsidiary thereof of the Loan Documents to which each such Person is a party, in accordance with their respective terms, the Extensions of Credit hereunder, the granting of the Liens under the Security Documents and the transactions contemplated hereby do not and will not, by the passage of time, the giving of notice or otherwise, (i) require any Governmental Approval or violate any Applicable Law relating to any Borrower or any Subsidiary thereof, (ii) conflict with, result in a breach of or constitute a default under (A) the articles of incorporation, bylaws or other organizational documents of any Borrower or any Subsidiary thereof or (B) any indenture, agreement or other instrument to which such Person is a party or by which any of its properties may be bound or any Governmental Approval relating to such Person which could reasonably be expected to have a Material Adverse Effect, or (iii) result in or require the creation or imposition of any Lien upon or with respect to any property now owned or hereafter acquired by such Person other than Liens arising under the Loan Documents.

(e) Compliance with Law; Governmental Approvals. Each Borrower and each Subsidiary thereof (i) has all Governmental Approvals required by any Applicable Law for it to conduct its business, each of which is in full force and effect, is final and not subject to review on appeal and is not the subject of any pending or, to the best of its knowledge, threatened attack by direct or collateral proceeding, and (ii) is in compliance with each Governmental Approval applicable to it and in compliance with all other Applicable Laws relating to it or any of its respective properties, in each case except to the extent that any such lack of Governmental Approval or failure to comply would not have a Material Adverse Effect.

(f) Tax Returns and Payments. Each Borrower and each Subsidiary thereof has duly filed or caused to be filed all federal, state, material local and other tax returns required by Applicable Law to be filed, and has paid, or made adequate provision for the payment of, all federal, state, local and other taxes, assessments and governmental charges or levies upon it and its property, income, profits and assets which are due and payable. Except as set forth on Schedule 7.1(f) and except for claims for taxes which are being contested in good faith and as to which adequate reserves are maintained in accordance with GAAP, no Governmental Authority has asserted any Lien or other claim against any Borrower or Subsidiary thereof with respect to unpaid taxes which has not been discharged or resolved. The charges, accruals and reserves on the books of each Borrower and each Subsidiary thereof in

respect of federal, state, material local and other taxes for all Fiscal Years and portions thereof since the organization of such Borrower and each Subsidiary thereof are in the judgment of each such Borrower adequate, and each such Borrower does not anticipate any additional taxes or assessments for any of such years.

(g) Intellectual Property Matters. Each Borrower and each Subsidiary thereof owns or possesses rights to use all franchises, licenses, copyrights, copyright applications, patents, patent rights or licenses, patent applications, trademarks, trademark rights, trade names, trade name rights, copyrights and rights with respect to the foregoing which are required to conduct its business. No event has occurred which permits, or after notice or lapse of time or both would permit, the revocation or termination of any such rights, and no Borrower nor any Subsidiary thereof is liable to any Person for infringement under Applicable Law with respect to any such rights as a result of its business operations.

(h) Environmental Matters. In the ordinary course of its business, each Borrower conducts an ongoing review of the effect of Environmental Laws on the business, operations and properties of such Borrower and its Subsidiaries, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted at any such facility, any costs or liabilities in connection with off-site disposal of wastes or Hazardous Substances, and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). On the basis of this review, each Borrower has concluded that such associated liabilities and costs, including the costs of compliance with Environmental Laws, could not reasonably be expected to have a Material Adverse Effect.

(j) Margin Stock. No Borrower nor any Subsidiary thereof is engaged principally or as one of its activities in the business of extending credit for the purpose of "purchasing" or "carrying" any "margin stock" (as each such term is defined or used in Regulation U of the Board of Governors of the Federal Reserve System).

SECTION 12.2 Remedies. Upon the occurrence and during the continuation of an Event of Default, with the consent of the Required Lenders, the Administrative Agent may, or upon the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrowers:

(a) Acceleration; Termination of Facilities. Declare the principal of and interest on the Loans, the Notes and the Reimbursement Obligations at the time outstanding, and all other amounts owed to the Lenders and to the Administrative Agent under this Agreement or any of the other Loan Documents (other than any Hedging Agreement) (including, without limitation, all L/C Obligations, whether or not the beneficiaries of the then outstanding Letters of Credit shall have presented the documents required thereunder) and all other Obligations (other than obligations owing under any Hedging Agreement), to be forthwith due and payable, whereupon the same shall immediately become due and payable without presentment, demand, protest or other notice of any kind, all of which are expressly waived, anything in this Agreement or the other Loan Documents to the contrary notwithstanding, and terminate the Credit Facility and any right of the Borrowers to request borrowings or Letters of Credit thereunder; provided, that upon the occurrence of an Event of Default specified in Section 12.1(j) or (k), the Credit Facility shall be automatically terminated and all Obligations (other than obligations owing under any Hedging Agreement) shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived.

With respect to all Letters of Credit with respect to which presentment for honor shall not have occurred at the time of an acceleration pursuant to the preceding paragraph, require the Borrowers at such time to deposit in a cash collateral account opened by the Administrative Agent an amount equal to the aggregate then undrawn and unexpired amount of such Letters of Credit.

No delay or failure to take action on the part of the Administrative Agent or any Lender in exercising any right, power or privilege shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege preclude other or further exercise thereof or the exercise of any other right, power or privilege or shall be construed to be a waiver of any Event of Default. No course of dealing between the Borrowers, the Administrative Agent and the Lenders or their respective agents or employees shall be effective to change, modify or discharge any provision of this Agreement or any of the other Loan Documents or to constitute a waiver of any Event of Default.

SECTION 13.1 Appointment. Each of the Lenders hereby irrevocably designates and appoints Wachovia as Administrative Agent and as Collateral Agent of such Lender, in each case, under this Agreement and the other Loan Documents for the term hereof and each such Lender irrevocably authorizes each of Wachovia as Administrative Agent and as Collateral Agent for such Lender, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to such Agent by the terms of this Agreement and such other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement or such other Loan Documents, neither Agent shall have any duties or responsibilities, except those expressly set forth herein and therein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or the other Loan Documents or otherwise exist against any Agent. Any reference to the Agent in this Article XIII shall be deemed to refer to the Administrative Agent or Collateral Agent, as applicable, solely in its capacity as Administrative Agent or Collateral Agent, as applicable, and not in its capacity as a Lender.

SECTION 13.2 Delegation of Duties. The Agents may execute any of their respective duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. No Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by such Agent with reasonable care.

SECTION 13.3 Exculpatory Provisions. Neither Agent nor any of such Agent's officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or Affiliates shall be (a) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or the other Loan Documents (except for actions occasioned solely by its or such Person's own gross negligence or willful misconduct), or (b) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Borrower or any Subsidiary thereof or any officer thereof contained in this Agreement or the other Loan Documents or in any certificate, report, statement or other document referred to or provided for in, or received by such Agent under or in connection with, this Agreement or the other Loan Documents or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or the other Loan Documents or for any failure of any Borrower or any Subsidiary thereof to perform its obligations hereunder or thereunder. No Agent 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 to inspect the properties, books or records of the Borrowers or any of their Subsidiaries.

SECTION 13.4 Reliance by the Agents. The Agents shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by such Agent 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 (including, without limitation, counsel to the Borrowers), independent accountants and other experts selected by such Agent. The Agents may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 14.10 hereof. The Agents shall be fully justified in failing or refusing to take any action under this Agreement and the other Loan Documents unless such Agent shall first receive such advice or concurrence of the Required Lenders (or, when expressly required hereby or by the relevant other Loan Document, all the Lenders) as it deems appropriate or 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 except for its own gross negligence or willful misconduct. The Agents shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the Notes in accordance with a request of the Required Lenders (or, when expressly required hereby, all the Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Notes.

SECTION 13.5 Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless it has received notice from a Lender or the Borrowers referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that any Agent receives such a notice, it shall promptly give notice thereof to the other Agent and to the Lenders. The Agents shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; provided that unless and until such Agent shall have received such directions, such 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 in the best interests of the Lenders, except to the extent that other provisions of this Agreement expressly require that any such action be taken or not be taken only with the consent and authorization or the request of the Lenders or Required Lenders, as applicable.

SECTION 13.6 Non-Reliance on the Agents and Other Lenders. Each Lender expressly acknowledges that neither Agent nor any of such Agent's officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or Affiliates has made any representations or warranties to it and that no act by any Agent hereinafter taken, including any review of the affairs of the Borrowers or any of their Subsidiaries, shall be deemed to constitute any representation or warranty by such Agent to any Lender. Each Lender represents to each Agent that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrowers and their Subsidiaries and made its own decision to make its Loans and issue or participate in Letter of Credit hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent 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 analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrowers and their Subsidiaries. Except for notices, reports and other documents expressly required to be furnished to the Lenders by an Agent hereunder or by the other Loan Documents, no Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, financial and other condition or creditworthiness of the Borrowers or any of their Subsidiaries which may come into the possession of any Agent or any of its respective officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or Affiliates.

SECTION 13.7 Indemnification. The Lenders agree to indemnify each Issuing Lender and each of the Administrative Agent, Collateral Agent, Documentation Agent and Syndication Agent in its respective capacity as such and (to the extent not reimbursed by the Borrowers and without limiting the obligation of the Borrowers to do so), ratably according to the respective amounts of their Revolving Credit Commitment Percentage, Term A Loan Percentage and/or Term B Loan Percentage, as applicable, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Notes or any Reimbursement Obligation) be imposed on, incurred by or asserted against any Agent in any way relating to or arising out of this Agreement or the other Loan Documents, or any documents contemplated by or referred to

herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by any Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from such Agent's bad faith, gross negligence or willful misconduct. The agreements in this Section 13.7 shall survive the payment of the Notes, any Reimbursement Obligation and all other amounts payable hereunder and the termination of this Agreement.

SECTION 13.8 The Agents in Their Individual Capacity. Each Agent and its respective Subsidiaries and Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrowers as though such Agent were not an Agent hereunder. With respect to any Loans made or renewed by it and any Note issued to it and with respect to any Letter of Credit issued by it or participated in by it, such Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms "Lender" and "Lenders" shall include the Agent in its individual capacity, if applicable.

SECTION 13.9 Resignation of the Agents; Successor Agents. Subject to the appointment and acceptance of a successor as provided below, any Agent may resign at any time by giving notice thereof to the Lenders and the Borrowers. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Agent, which successor shall have minimum capital and surplus of at least $500,000,000. If no successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after such Agent's giving of notice of resignation, then such Agent may, on behalf of the Lenders, appoint a successor Agent, which successor shall have minimum capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation hereunder as Agent, the provisions of this Section 13.9 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent.

Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of the venue of any such proceeding brought in any court specified above and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

(a) Jury Trial. TO THE EXTENT PERMITTED BY LAW, THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT, THE DOCUMENTATION AGENT, THE SYNDICATION AGENT, EACH LENDER AND EACH BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY JUDICIAL PROCEEDING, ANY DISPUTE, CLAIM OR CONTROVERSY ARISING OUT OF, CONNECTED WITH OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENTS ("DISPUTES") IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

(a) The Borrowers recognize that, in the event any Borrowers fails to perform, observe or discharge any of its obligations or liabilities under this Agreement, any remedy of law may prove to be inadequate relief to the Lenders.

(e) To the extent that any Borrower would, but for the operation of this Section 14.19, be rendered insolvent under any Applicable Law by reason of its incurring of obligations to any other Borrower under the foregoing subsections (c) and (d) above, such Borrower shall, in turn, have rights of contribution and indemnity, to the full extent provided in the foregoing subsections (c) and (d) above, against the remaining Borrowers, such that all Obligations of all of the Borrowers hereunder and under this Section 14.19 shall be allocated in a manner such that no Borrower shall be rendered insolvent for any purpose under Applicable Law by reason of its incurring of such obligations.

(f) The rights of any Borrower to contribution, subrogation and indemnity under this Section 14.19 or under Applicable Law shall in all events and all respects be subject and subordinate to the rights of the Administrative Agent and the Lenders under this Agreement and subject to the prior full, final and indefeasible payment to the Administrative Agent and the Lenders of all Obligations and no such right may be exercised until all of such Obligations have been fully, finally and indefeasibly paid and such payments are in no event subject to avoidance under Title 11 of the United States Code or any other Applicable Law.

SECTION 14.20 Inconsistencies with Other Documents; Independent Effect of Covenants.

(a) In the event there is a conflict or inconsistency between this Agreement and any other Loan Document, the terms of this Agreement shall control; provided, that any provision of the Security Documents which imposes additional burdens on any Borrower or any Subsidiary thereof or further restricts the rights of any Borrower or any Subsidiary thereof or gives the Agents or Lenders additional rights shall not be deemed to be in conflict or inconsistent with this Agreement and shall be given full force and effect.

(b) The Borrowers expressly acknowledge and agree that each covenant contained in Articles IX, X, or XI hereof shall be given independent effect. Accordingly, the Borrowers shall not engage in any transaction or other act otherwise permitted under any covenant contained in Articles IX, X, or XI if, before or after giving effect to such transaction or act, the Borrowers shall or would be in breach of any other covenant contained in Articles IX, X, or XI.
