SECTION 2.

AMOUNT AND TERMS OF COMMITMENTS

2.1 Revolving Commitments.

(a) Subject to the terms and conditions hereof, each Lender severally agrees to make revolving credit loans (“Revolving Loans”) to the Borrower from time to time during the Revolving Commitment Period in an aggregate principal amount at any one time outstanding which, when added to such Lender’s Revolving Percentage of the aggregate principal amount of the Swingline Loans then outstanding, does not exceed the amount of such Lender’s Revolving Commitment. During the Revolving Commitment Period, the Borrower may use the Revolving Commitments by borrowing, prepaying the Revolving Loans in whole or in part, and reborrowing, all in accordance with the terms and conditions hereof. The Revolving Loans may from time to time be Eurodollar Loans or ABR Loans, as determined by the Borrower and notified to the Administrative Agent in accordance with Sections 2.2 and 2.10. Unless an earlier maturity is provided for hereunder, each Revolving Loan shall mature and be due and payable on the Applicable Repayment Date for such Revolving Loan.

(b) Notwithstanding the foregoing, no Lender shall be obligated to make a Revolving Loan hereunder if the aggregate principal amount at any one time outstanding of such Lender’s Revolving Percentage of the Total Revolving Extensions of Credit exceeds such Lender’s Revolving Commitment.

(c) The obligations of the Lenders hereunder to make Loans and to make payments pursuant to Section 8.7 are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any such payment on any date shall not relieve any other Lender of its corresponding obligation, if any, hereunder to do so on such date, but no Lender shall be responsible for the failure of any other Lender to so make its Loan, purchase its participation or to make any such payment required hereunder.

(d) The Borrower shall repay all outstanding Revolving Loans on the Revolving Termination Date.

2.2 Procedure for Revolving Loan Borrowing. The Borrower may borrow under the Revolving Commitments during the Revolving Commitment Period on any Business Day; provided that the Borrower shall give the Administrative Agent irrevocable notice (which notice must be received by the Administrative Agent prior to 11:00 a.m., Charlotte, North Carolina time, (a) three Business Days prior to the requested Borrowing Date, in the case of Eurodollar Loans, or (b) on the requested Borrowing Date, in the case of ABR Loans), specifying (i) the amount and Type of Revolving Loans to be borrowed, (ii) the requested Borrowing Date and (iii) in the case of Eurodollar Loans, the respective lengths of the initial Interest Period therefor. Each borrowing under the Revolving Commitments shall be in an amount equal to (x) in the case of ABR Loans, $1,000,000 or a whole multiple of $100,000 in excess thereof, and (y) in the case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof; provided, however, that the Swingline Lender may request, on behalf of the Borrower, borrowings under the Revolving Commitments that are ABR Loans in other amounts pursuant to Section 2.3(d). Upon receipt of any such notice from the Borrower, the Administrative Agent shall promptly notify each Lender thereof. Each Lender will make its Revolving Percentage of each borrowing available to the Administrative Agent for the account of the Borrower at the Funding Office prior to 1:00 p.m., Charlotte, North Carolina time, on the Borrowing Date requested by or on behalf of the Borrower in funds immediately available to the Administrative Agent. Such borrowing will then be made available to the Borrower by the Administrative Agent crediting the account of the Borrower on the books of such Funding Office with the aggregate of the amounts made available to the Administrative Agent by the Lenders and in like funds as received by the Administrative Agent or, at the Borrower’s option, by effecting a wire transfer of such amounts to an account designated by the Borrower to the Administrative Agent.

2.3 Swingline Commitment.

(a) Subject to the terms and conditions hereof, the Swingline Lender agrees to make a portion of the credit otherwise available to the Borrower under the Revolving Commitments from time to time during the Revolving Commitment Period by making swing line loans (“Swingline Loans”) to the Borrower; provided that (i) the aggregate principal amount of Swingline Loans outstanding at any time shall not exceed the Swingline Commitment then in effect (notwithstanding that the Swingline Loans outstanding at any time, when aggregated with

the Swingline Lender’s other outstanding Revolving Loans, may exceed the Swingline Commitment then in effect), (ii) the Borrower shall not request, and the Swingline Lender shall not make, any Swingline Loan if, after giving effect to the making of such Swingline Loan, the aggregate amount of the Available Revolving Commitments would be less than zero and (iii) the Swingline Lender shall not make any Swingline Loan if any Lender is at that time a Defaulting Lender, unless the Swingline Lender has entered into arrangements, including the delivery of Cash Collateral, satisfactory to Swingline Lender (in its sole discretion) with the Borrower or such Lender to eliminate the Swingline Lender’s actual or potential Fronting Exposure (after giving effect to Section 2.23(a)(iv)) with respect to the Defaulting Lender arising from either the Swingline Loan then proposed to be made or that Swingline Loan and all other Swingline Loans as to which the Swingline Lender has actual or potential Fronting Exposure, as it may elect in its sole discretion; and provided, further, that the Borrower shall not use the proceeds of any Swingline Loan to refinance any outstanding Swingline Loan. During the Revolving Commitment Period, the Borrower may use the Swingline Commitment by borrowing, repaying and reborrowing, all in accordance with the terms and conditions hereof. Each Swingline Loan shall, at the election of the Borrower, accrue interest at either (x) the LIBOR Market Index Rate plus the Applicable Margin for Eurodollar Loans or (y) the ABR plus the Applicable Margin for ABR Loans, in each case as such rate is in effect from time to time while such Swingline Loan is outstanding. Immediately upon the making of a Swingline Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan in an amount equal to the product of such Lender’s Revolving Percentage times the amount of such Swingline Loan.

(b) The Borrower shall repay (i) each outstanding Swingline Loan not later than 14 Business Days after the date such Swingline Loan was advanced pursuant to Section 2.3(a), and (ii) all outstanding Swingline Loans on the Revolving Termination Date. Unless an earlier maturity is provided for hereunder, Swingline Loans shall mature and be due and payable on the Applicable Repayment Date for such Swingline Loan.

(c) The Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Loans. Until each Lender funds its Refunded Swingline Loan pursuant to Section 2.4 with respect to any Swingline Loan made by the Swingline Lender, interest in respect of such Lender’s Revolving Percentage of such Swingline Loan shall be solely for the account of the Swingline Lender.

(d) The Borrower shall make all payments of principal and interest in respect of the Swingline Loans directly to the Swingline Lender.

2.4 Procedure for Swingline Borrowing; Refunding of Swingline Loans.

(a) Whenever the Borrower desires that the Swingline Lender make Swingline Loans, it shall give the Administrative Agent and the Swingline Lender irrevocable telephonic notice confirmed promptly in writing (which telephonic notice must be received by the Swingline Lender not later than 1:00 P.M., Charlotte, North Carolina time, on the proposed Borrowing Date), specifying (i) the amount to be borrowed, (ii) the requested Borrowing Date (which shall be a Business Day during the Revolving Commitment Period) and (iii) whether the Borrower elects for such Swingline Loan to accrue interest at the LIBOR Market Index Rate plus the

Applicable Margin for Eurodollar Loans or at the ABR plus the Applicable Margin for ABR Loans. Each borrowing under the Swingline Commitment shall be in an amount equal to $1,000,000 or a whole multiple of $100,000 in excess thereof. Not later than 3:00 P.M., Charlotte, North Carolina time, on the Borrowing Date specified in a notice in respect of Swingline Loans, the Swingline Lender shall make available to the Administrative Agent at the Funding Office an amount in immediately available funds equal to the amount of the Swingline Loan to be made by the Swingline Lender. The Administrative Agent shall make the proceeds of such Swingline Loan available to the Borrower on such Borrowing Date by depositing such proceeds in the account of the Borrower with the Administrative Agent on such Borrowing Date in immediately available funds or, at the Borrower’s option, by effecting a wire transfer of such amounts to an account designated by the Borrower to the Administrative Agent.

(b) The Swingline Lender, at any time and from time to time in its sole and absolute discretion may, on behalf of the Borrower (which hereby irrevocably directs the Swingline Lender to act on its behalf), on one Business Day’s notice given by the Swingline Lender to the Administrative Agent no later than 12:00 Noon, Charlotte, North Carolina time, request each Lender to make, and each Lender hereby agrees to make, a Revolving Loan, in an amount equal to such Lender’s Revolving Percentage of the aggregate amount of the Swingline Loans (the “Refunded Swingline Loans”) outstanding on the date of such notice, together with all interest accrued and unpaid thereon, to repay the Swingline Lender. Revolving Loans made pursuant to this Section 2.4(b) initially shall bear interest at the ABR plus the Applicable Margin for ABR Loans. Each Lender shall make the amount of such Revolving Loan available to the Administrative Agent at the Funding Office in immediately available funds, not later than 10:00 A.M., Charlotte, North Carolina time, one Business Day after the date of such notice. The proceeds of such Revolving Loans shall be immediately made available by the Administrative Agent to the Swingline Lender for application by the Swingline Lender to the repayment of the Refunded Swingline Loans and all interest accrued and unpaid thereon. The Borrower irrevocably authorizes the Swingline Lender to charge the Borrower’s accounts with the Administrative Agent (up to the amount available in each such account) in order to immediately pay the amount of such Refunded Swingline Loans and all interest accrued and unpaid thereon to the extent amounts received from the Lenders are not sufficient to repay in full such Refunded Swingline Loans and all interest accrued and unpaid thereon. The Administrative Agent shall give the Borrower prompt notice of any such charge against the Borrower’s account.

(c) If prior to the time a Revolving Loan would have otherwise been made pursuant to Section 2.4(b), one of the events described in Section 7(f) shall have occurred and be continuing with respect to the Borrower or if for any other reason, as determined by the Swingline Lender in its sole discretion, Revolving Loans may not be made as contemplated by Section 2.4(b), each Lender shall, on the date such Revolving Loan was to have been made pursuant to the notice referred to in Section 2.4(b) (the “Refunding Date”), purchase for cash an undivided participating interest in the then outstanding Swingline Loans by paying to the Swingline Lender an amount (the “Swingline Participation Amount”) equal to (i) such Lender’s Revolving Percentage times (ii) the sum of the aggregate principal amount of Swingline Loans then outstanding, together with all interest accrued and unpaid thereon, that were to have been repaid with such Revolving Loans.

(d) Whenever, at any time after the Swingline Lender has received from any Lender such Lender’s Swingline Participation Amount, the Swingline Lender receives any payment on account of the Swingline Loans, the Swingline Lender will distribute to such Lender its Swingline Participation Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded and, in the case of principal and interest payments, to reflect such Lender’s pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all Swingline Loans then due); provided, however, that in the event that such payment received by the Swingline Lender is required to be returned, such Lender will return to the Swingline Lender any portion thereof previously distributed to it by the Swingline Lender.

(e) Each Lender’s obligation to make the Loans referred to in Section 2.4(b) and to purchase participating interests pursuant to Section 2.4(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such Lender or the Borrower may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 4; (iii) any adverse change in the condition (financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other Loan Document by the Borrower or any other Lender; or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

2.5 Evidence of Debt.

(a) Each Lender shall maintain in accordance with its usual practice appropriate records evidencing indebtedness of the Borrower 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 in respect of such Loans. The Administrative Agent shall maintain the Register pursuant to Section 9.6(f), and a record therein for each Lender, in which shall be recorded (i) the amount of each Loan made by such Lender, the interest rate applicable thereto and each Interest Payment Date applicable thereto, and (ii) the amount of any sum received by the Administrative Agent hereunder from the Borrower on account of such Loan. The entries made in the Register and the records of each Lender maintained pursuant to this Section 2.5 shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any such record, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Loans made by such Lender in accordance with the terms of this Agreement.

(b) At the request of any Lender (including the Swingline Lender) at any time, the Borrower agrees that it will execute and deliver to such Lender a Revolving Note evidencing the Revolving Loans of such Lender and, in the case of the Swingline Lender only, a Swingline Note evidencing the Swingline Loans of the Swingline Lender, payable to the order of such Lender.

2.6 Facility Fees, etc.

(a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender in accordance with its Revolving Percentage a facility fee for the period from and including the date hereof to the Revolving Termination Date, computed at the Facility Fee Rate on the average daily amount of the Revolving Commitment of such Lender in effect (whether or not then being used) during the period for which payment is made, payable quarterly in arrears on the last day of each March, June, September and December and on the Revolving Termination Date, commencing on December 31, 2011; provided, however, that no facility fee shall accrue on the Revolving Commitment of a Defaulting Lender during any period that such Lender shall be a Defaulting Lender.

(b) The Borrower agrees to pay to the Administrative Agent, Wells Fargo Bank and the Arrangers the fees in the amounts and on the dates previously agreed to in the Fee Letters.

2.7 Termination or Reduction of Revolving Commitments. The Borrower shall have the right, upon not less than three Business Days’ notice to the Administrative Agent, to terminate the Revolving Commitments or, from time to time, to reduce the amount of the Revolving Commitments; provided that no such termination or reduction of Revolving Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof pursuant to Section 2.9, the Total Revolving Extensions of Credit would exceed the Total Revolving Commitments. Any such reduction shall be in an amount equal to $10,000,000, or an integral multiple of $1,000,000 in excess thereof, and shall reduce permanently the Revolving Commitments then in effect. The Administrative Agent will promptly notify the Lenders of any such notice of termination or reduction of the Revolving Commitments.

2.8 Optional Prepayments. The Borrower may at any time and from time to time prepay the Loans, in whole or in part, without premium or penalty, upon irrevocable notice delivered to the Administrative Agent at least three Business Days prior thereto in the case of Eurodollar Loans and no later than 11:00 a.m., Charlotte time, on the date of such prepayment in the case of ABR Loans, which notice shall specify the date and amount of prepayment and whether the prepayment is of Eurodollar Loans or ABR Loans; provided, that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.18. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to such date on the amount prepaid. Partial prepayments of the Loans shall be in an aggregate principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof. Partial prepayments of Swingline Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple of $100,000 in excess thereof.

2.9 Prepayments on Revolving Commitment Reductions. Any reduction of the Revolving Commitments shall be accompanied by prepayment of the Revolving Loans and/or Swingline Loans to the extent, if any, that the Total Revolving Extensions of Credit would exceed the amount of the Total Revolving Commitments as so reduced; provided that if the aggregate principal amount of Revolving Loans and Swingline Loans then outstanding is less than the amount of such excess, the Borrower shall, to the extent of the balance of such excess and/or deposit an amount in cash in a cash collateral account established with the Administrative

Agent for the benefit of the Lenders on terms and conditions satisfactory to the Administrative Agent. The application of any prepayment pursuant to this Section 2.9 shall be made, first, to ABR Loans and, second, to Eurodollar Loans. Each prepayment of the Loans under this Section 2.9 shall (i) be accompanied by accrued interest to the date of such prepayment on the amount prepaid and (ii) be applied to the Loans of the Lenders in accordance with their respective Revolving Percentages.

2.10 Conversion and Continuation Options.

(a) The Borrower may elect from time to time to convert Eurodollar Loans to ABR Loans by giving the Administrative Agent at least two Business Days’ prior irrevocable notice of such election, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert ABR Loans to Eurodollar Loans by giving the Administrative Agent at least three Business Days’ prior irrevocable notice of such election (which notice shall specify the length of the initial Interest Period therefor), provided that no ABR Loan may be converted into a Eurodollar Loan when a Default or an Event of Default has occurred and is continuing. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans, provided that no such continuation shall extend beyond the Applicable Repayment Date of such Eurodollar Loan and that no such Eurodollar Loan may be continued as such when any Default or Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to ABR Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

2.11 Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (b) no more than six Eurodollar Tranches shall be outstanding at any one time.

2.12 Interest Rates and Payment Dates.

(a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin for Eurodollar Loans.

(b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin for ABR Loans.

(d) Upon the occurrence and during the continuance of any Event of Default under Sections 7(a) or 7(f), or (at the election of the Required Lenders) upon the occurrence and during the continuance of any other Event of Default, all outstanding principal amounts of the Loans and, to the greatest extent permitted by law, all interest accrued on the Loans and all other accrued and outstanding fees and other amounts hereunder, shall bear interest at a rate per annum equal to the interest rate applicable from time to time thereafter to such Loans (whether the ABR plus the Applicable Margin or the Eurodollar Rate plus the Applicable Margin) plus 2% (or, in the case of interest, fees and other amounts for which no rate is provided hereunder, at the ABR (plus the Applicable Margin) plus 2%), and, in each case, such default interest shall be payable on demand. To the greatest extent permitted by law, interest shall continue to accrue after the filing by or against the Borrower of any petition seeking any relief in bankruptcy or under any law pertaining to insolvency or debtor relief.

(e) Interest in respect of all Revolving Loans and all Swingline Loans shall be payable in arrears on each Interest Payment Date. Notwithstanding the foregoing, interest accruing pursuant to paragraph (d) of this Section shall be payable from time to time on demand.

2.13 Computation of Interest and Fees.

(a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to ABR Loans the rate of interest on which is calculated on the basis of the Prime Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.12(a).

2.14 Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(i) the Administrative Agent shall have determined in its reasonable and good faith judgment (which determination shall be conclusive and binding upon the Borrower)

that, by reason of circumstances affecting the relevant market, adequate means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(ii) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the actual cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period;

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent (upon the instruction of the Required Lenders in the case of clause (ii) above), no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Loans to Eurodollar Loans. The Administrative Agent shall promptly withdraw such notice when Eurodollar Loans are again available.

2.15 Pro Rata Treatment and Payments.

(a) Each borrowing by the Borrower from the Lenders hereunder (other than the borrowing of Swingline Loans), and, subject to Section 2.23(a), each payment by the Borrower on account of any facility fee and any reduction of the Revolving Commitments of the Lenders shall be made according to the respective Revolving Percentage of each of the relevant Lenders.

(b) Subject to Section 2.23(a), each payment (including each prepayment) by the Borrower on account of principal of and interest on the Loans shall be made according to the respective Revolving Percentage of each Lender.

(c) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, Charlotte, North Carolina time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(d) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans, on demand, from the Borrower.

(e) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

2.16 Requirements of Law.

(a) If any Change in Law:

(i) shall subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) the imposition of, or any change in the rate of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto;

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

(iii) shall impose any other condition on such Lender or such other Recipient;

and the result of any of the foregoing is to increase the cost to such Lender or such other Recipient by an amount that such Lender or such other Recipient deems to be material, of making, converting into, continuing or maintaining any Loans, or to reduce any amount received or receivable hereunder in respect thereof (whether of principal, interest or any other amount), then, in any such case, the Borrower shall promptly pay such Lender or such other Recipient, upon its demand, any additional amounts necessary to compensate such Lender or such other Recipient for such increased cost or reduced amount receivable. If any Lender or other Recipient becomes entitled to claim any amounts pursuant to this paragraph, it shall promptly notify the Borrower in writing (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled; provided that the Borrower shall not be required to compensate a Lender or other Recipient pursuant to this paragraph for any amounts incurred more than three months prior to the date that such Lender or such other Recipient notifies the Borrower of such Lender’s or such other Recipient’s intention to claim compensation therefor; and provided further that, if the circumstances giving rise to such claim have a retroactive effect, then such period for which the Borrower shall be required to compensate the Lenders and any other Recipients shall be extended to include the period of such retroactive effect.

(b) If any Lender shall have determined that any Change in Law regarding capital requirements shall have the effect of reducing the rate of return on such Lender’s or such Lender’s holding company’s capital as a consequence of its obligations hereunder to a level below that which such Lender or such Lender’s holding company could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for such reduction; provided that the Borrower shall not be required to compensate a Lender pursuant to this paragraph for any amounts incurred more than three months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; and provided further that, if the circumstances giving rise to such claim have a retroactive effect, then such period for which the Borrower shall be required to compensate the Lenders shall be extended to include the period of such retroactive effect

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender or any other Recipeint to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.17 Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower under this Agreement or any other any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall

timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify each Recipient, within ten days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient, or required to be withheld or deducted from a payment to such Recipient, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Failure or delay on the part of any Recipient to demand compensation pursuant to this Section shall not constitute a waiver of such Recipient’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Recipient pursuant to this Section for any Indemnified Taxes imposed or asserted against such Recipient more than 90 days prior to the date that such Recipient notifies the Borrower of the imposition or assertion of such Indemnified Taxes and of such Recipient’s intention to claim indemnification therefor (except that, if the imposition or assertion of such Indemnified Taxes giving rise to such claim for indemnification is retroactive, then the 90 day period referred to above shall commence on the date such Recipient obtains knowledge of the same). A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.6(b) relating to the maintenance of the Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with this Agreement or any other Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (d).

(e) Whenever any Indemnified Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall, to the extent reasonably available to the Borrower, send to

the Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof.

(f) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 2.17(f)(i), 2.17(f)(ii) and 2.17(g) below) shall not be required (i) if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or (ii) if such Lender is not legally able or permitted to complete, execute and submit such documentation.

Without limiting the generality of the foregoing, in the event that the Borrower is resident for tax purposes in the United States,

(i) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(ii) any Non-U.S. Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Non-U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(A) in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(B) executed originals of IRS Form W-8ECI;

(C) in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Non-U.S. Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or

(D) to the extent a Non-U.S. Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Non-U.S. Lender is a partnership and one or more direct or indirect partners of such Non-U.S. Lender are claiming the portfolio interest exemption, such Non-U.S. Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner;

(iii) any Non-U.S. Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Non-U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(g) If a payment made to a Lender under any Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender fails to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent (A) a certification signed by the chief financial officer, principal accounting officer, treasurer or controller, and (B) other documentation reasonably requested by the Borrower and the Administrative Agent sufficient for the Administrative Agent and the Borrower to comply with their obligations under FATCA and to determine that such Lender has complied with such applicable reporting requirements.

(h) Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent of its legal inability to do so.

(i) If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.17 (including by the payment of additional amounts pursuant to this Section 2.17), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (i) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(j) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder and for a period of one year after the indefeasible payment in full of all Obligations and the termination of this Agreement and the other Loan Documents.

2.18 Compensation. The Borrower will compensate each Lender upon demand for all losses, expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund or maintain Eurodollar Loans but excluding loss of profits) that such Lender may incur or sustain (i) if for any reason (other than a default by such Lender) a Borrowing or continuation of, or conversion into, a Eurodollar Loan does not occur on a date specified therefor in the notice of borrowing or notice of conversion/continuation provided by the Borrower to the Administrative Agent, (ii) if any repayment, prepayment or conversion of any Eurodollar Loan occurs on a date other than the last day of an Interest Period applicable thereto (including as a consequence of any assignment made pursuant to Section 2.21 or any acceleration of the maturity of the Loans pursuant to Section 8.2), (iii) if any prepayment of any Eurodollar Loan is not made on any date specified in a notice of prepayment given by the Borrower or (iv) as a consequence of any other failure by the Borrower to make any payments with respect to any Eurodollar Loan when due hereunder. Calculation of all amounts payable to a Lender under this Section 2.18 shall be made as though such Lender had actually funded its relevant Eurodollar Loan through the purchase of a Eurodollar deposit bearing interest at the Eurodollar Rate in an amount equal to the amount of such Eurodollar Loan, having a maturity comparable to the relevant Interest Period; provided, however, that each Lender may fund its Eurodollar Loans in any manner it sees fit and the foregoing assumption shall be utilized only for the calculation of amounts payable under this Section 2.18. A certificate (which shall be in reasonable detail) showing the basis for the determinations set forth in this Section 2.18 by any Lender as to any additional amounts payable pursuant to this Section 2.18 shall be submitted by such Lender to the Borrower either directly or through the Administrative Agent. Determinations set forth in any such certificate made in good faith for purposes of this Section 2.18 of any such losses, expenses or liabilities shall be conclusive absent manifest error.

2.19 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.16, 2.17(a) or 2.20 with respect to such Lender, to the extent permitted by law, it will designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such Lender, are not disadvantageous to such Lender, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 2.16, 2.17(a) or 2.20.

2.20 Illegality. If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof shall make it unlawful, impossible or impracticable for any Lender to make, maintain or fund any Eurodollar Loan and such Lender shall so notify the Administrative Agent and the Borrower thereof (with supporting documentation) of such event, then such Lender’s Revolving Commitment shall be suspended and, 30 days following such notification, shall be canceled if such unlawfulness, impossibility or impracticability shall then be continuing. The Borrower shall prepay such Lender’s Loans or convert such Eurodollar Loans to ABR Loans at the time or times and to the extent necessary to avoid such unlawfulness, together with unpaid accrued interest thereon, unpaid accrued fees and any other amounts due and payable to such Lender, unless, in either case, prior thereto, the Borrower shall have given notice to such Lender that the Borrower will require such Lender to assign and transfer all of its interests in this Agreement pursuant to Section 2.21 and shall have caused such Lender to have so assigned and transferred such interests.

2.21 Replacement of Lenders. The Borrower shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.16 or 2.17(a), (b) requires relief pursuant to Section 2.20 or (c) is a Defaulting Lender or a Nonconsenting Lender, in each case with a replacement financial institution; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement, such Lender shall have taken no action under Section 2.19 so as to eliminate the continued need for payment of amounts owing pursuant to Section 2.16 or 2.17(a) or relief pursuant to Section 2.20, (iv) the replacement financial institution shall purchase, at par, all Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender for any amounts owing under Section 2.18 if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be an Eligible Assignee, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 9.6 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein), (viii) until such time as such replacement shall be consummated, the Borrower shall pay to the Lender being replaced all additional amounts (if any) required pursuant to Section 2.16 or 2.17(a), as the case may be, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender. If any circumstances arise which result, or such Lender becomes aware of any circumstances which are expected to result, in the Borrower having to make such compensation or indemnification or in it

becoming illegal for such Lender to make, fund or maintain such Lender’s Eurodollar Loans, such Lender shall use its commercially reasonable efforts to notify the Borrower thereof and, in consultation with the Borrower, such Lender shall take all steps, if any, it determines are reasonable and the Borrower determines are acceptable to mitigate the effect of those circumstances; provided that no delay or failure by any Lender to provide any such notice shall affect the obligations of the Borrower hereunder.

2.22 Increase in Revolving Commitments.

(a) Prior to the Revolving Termination Date, the Borrower may submit to the Administrative Agent the Borrower’s written request that the Revolving Commitments be increased, in each case by a minimum amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof, up to a total amount so that the Total Revolving Commitments do not exceed on any such occasion $900,000,000 (the requested amount on each such occasion being the “Maximum Revolving Commitments”), and the Administrative Agent shall promptly give notice of such request to each Lender (the “Revolving Commitment Increase Notice”). Within 15 Business Days after its receipt from the Administrative Agent of a Revolving Commitment Increase Notice, each Lender that desires to increase its Revolving Commitment in response to such request (each such Lender, a “Consenting Lender”) shall deliver written notice to the Administrative Agent of its election to increase its Revolving Commitment and the maximum amount of such increase (for each Consenting Lender, its “Additional Revolving Commitment”), which may not be larger than the excess of (a) the Maximum Revolving Commitments, over (b) the Total Revolving Commitments then in effect. The failure of any Lender to so notify the Administrative Agent of its election and its Additional Revolving Commitment, if any, shall be deemed to be a refusal by such Lender to increase its Revolving Commitment.

(b) If the sum of the Revolving Commitments then in effect plus the aggregate Additional Revolving Commitments pursuant to Section 2.22(a) is less than the Maximum Revolving Commitments, then the Borrower may obtain the remainder of the Maximum Revolving Commitment from one or more new banks or other financial institutions acceptable to the Borrower and the Administrative Agent (which acceptance shall not be unreasonably withheld) (each a “New Lender”). Upon (i) the execution of a Joinder Agreement with respect to this Agreement by such New Lender and acceptance thereof by the Administrative Agent, (ii) the execution and delivery by the Borrower of any Notes requested by the New Lender evidencing its Loans, and (iii) delivery of notice to the Lenders by the Administrative Agent setting forth the effective date of the addition of the New Lender(s) hereunder and the amount of such New Lender(s)’ Revolving Commitment(s), such New Lender(s) shall be for all purposes Lender(s) party to this Agreement to the same extent as if original parties hereto with Revolving Commitment(s) as set forth on the Joinder Agreement executed by the New Lender(s); provided, however, (i) the Total Revolving Commitments of all Lenders (including any New Lenders) shall not exceed in the aggregate the Maximum Revolving Commitments, and (ii) the Revolving Commitments of all Lenders that are parties hereto prior to the addition of any New Lender shall not be affected by the addition of such New Lender.

(c) If the Total Revolving Commitments are increased in accordance with this Section, the Administrative Agent and the Borrower shall determine the effective date (the

“Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final allocation of such increase and the Increase Effective Date.

(d) Prior to any increase in the Revolving Commitments becoming effective pursuant to this Section 2.22, Borrower shall deliver such opinions of counsel for the Borrower with respect thereto as the Administrative Agent may reasonably request, no Default or Event of Default shall then exist or have occurred and be continuing, and the other conditions set forth in Section 4.2 shall have been satisfied. Effective on the date on which the increase in Revolving Commitments pursuant to this Section 2.22 takes effect, which date shall be mutually agreed upon by the Borrower, the Administrative Agent, and each Lender or New Lender increasing or providing, as the case may be, its Revolving Commitments, (i) all Loans outstanding hereunder shall be converted into, and shall be advanced as, Eurodollar Loans or ABR Loans (or both) as selected by the Borrower by notice to the Administrative Agent in accordance with the provisions of Section 2.22, such that all such Loans are held by the Lenders (including any New Lenders) in the proportion of their Revolving Percentages, as determined taking into account the increase in the Revolving Commitments, and (ii) each New Lender and each other Lender increasing its Revolving Commitment shall advance any additional amounts to be advanced by it hereunder, by making funds available to the Administrative Agent, in immediately available funds, not later than 1:00 p.m. Charlotte, North Carolina time on such date. After the Administrative Agent’s receipt of such funds, the Administrative Agent shall disburse to the non-Consenting Lenders any resulting repayments of such outstanding Loans. If any conversion or payment of a Eurodollar Loan pursuant to the foregoing provisions occurs on a day that is not the last day of the applicable Interest Period, the provisions of Section 2.18 shall apply thereto.

2.23 Defaulting Lenders.

(a) Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders and in Section 9.1.

(ii) Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 7 or otherwise) shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Swingline Lender hereunder; third, if so determined by the Administrative Agent or requested by the Swingline Lender, to be held as Cash Collateral for future funding obligations of such Defaulting Lender in respect of any participation in any Swingline Loan; fourth, as the Borrower may request (so long as no Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative

Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of such Defaulting Lender to fund Loans under this Agreement; sixth, to the payment of any amounts then owing to the Lenders or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Swingline Lender against that Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default exists, to the payment of any amounts then owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans in respect of which such Defaulting Lender has not fully funded its share, and (y) such Loans were made at a time when the conditions set forth in Section 4.2 were satisfied or waived, such payment shall be applied to pay the Loans of all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of such Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Any Defaulting Lender shall be entitled to receive any Facility Fee for any period during which that Lender is a Defaulting Lender only to extent allocable to the sum of (1) the outstanding amount of the Revolving Loans funded by it, and (2) its Revolving Percentage of the stated amount of Swingline Loans for which it has provided Cash Collateral pursuant to Section 2.23(c) (and the Borrower shall (A) be required to pay the Swingline Lender the amount of such fee allocable to its Fronting Exposure arising from that Defaulting Lender, and (B) not be required to pay the remaining amount of such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(iv) All or any part of such Defaulting Lender’s Swingline Exposure shall automatically (effective on the day such Lender becomes a Defaulting Lender) be reallocated among the non-Defaulting Lenders in accordance with their respective Revolving Percentages (calculated without regard to such Defaulting Lender’s Revolving Commitment) but only to the extent that (x) no Default shall have occurred and be continuing (and, unless the Borrower shall have otherwise notified the Administrative Agent at the time, the Borrower shall be deemed to have represented and warranted that such condition is satisfied at such time), and (y) such reallocation does not cause the Revolving Extensions of Credit of any non-Defaulting Lender to exceed such non-Defaulting Lender’s Revolving Commitment. For the avoidance of doubt and notwithstanding any provision in this Agreement to the contrary, the Borrower shall not be required under this Agreement to deliver to the Administrative Agent any Cash Collateral unless and until the aggregate Revolving Commitment of all Lenders who are not Defaulting Lenders is less than the aggregate amount of all Revolving Extensions of Credit outstanding at such time.

(v) If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, within two Business Days following notice by the Administrative Agent, Cash Collateralize such Defaulting Lender’s Swingline Exposure (after giving effect to any partial reallocation pursuant to clause (iv) above) in accordance with the procedures set forth in Section 2.23(c) for so long as such Swingline Loans are outstanding.

(b) If the Borrower, the Administrative Agent and the Swingline Lender agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Revolving Loans and funded and unfunded participations in Swingline Loans to be held on a pro rata basis by the Lenders in accordance with their Revolving Percentages (without giving effect to Section 2.23(a)(iv), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of the Borrower or any other party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) At any time that there shall exist a Defaulting Lender, and to the extent that Cash Collateral is required to be delivered pursuant to Section 2.23(a), within two Business Days upon the request of the Administrative Agent or the Swingline Lender, the Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.23(a)(iv) and any Cash Collateral provided by the Defaulting Lender).

(i) All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts with the Administrative Agent. The Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent and the Lenders (including the Swingline Lender), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to clause (ii) below. If at any time the Administrative Agent reasonably determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, the Borrower or the relevant Defaulting Lender will, promptly upon demand by the Administrative Agent, pay or provide to the

Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(ii) Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this Section 2.23 in respect of Swingline Loans shall be held and applied to the satisfaction of the specific Swingline Loans, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

(iii) Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee)), or (ii) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of the Borrower shall not be released during the continuance of an Event of Default (and following application as provided in this Section 2.23 may be otherwise applied in accordance with Section 2.15), and (y) the Person providing Cash Collateral and the Swingline Lender may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

2.24 Extension of Facility Termination Date.

(a) So long as no Default or Event of Default has occurred and is continuing and subject to the satisfaction of the conditions set forth in Sections 2.24(b) and 2.24(c), the Borrower may, not more than two (2) times during the term of this Agreement, no earlier than sixty (60) days and no later than thirty (30) days prior to each anniversary of the Closing Date (such anniversary, an “Extension Date”) request through written notice to the Administrative Agent (the “Extension Notice”), that the Lenders extend the then existing Revolving Termination Date for an additional one-year period. Each Lender, acting in its sole discretion, shall, by notice to the Administrative Agent no later than the applicable Extension Date (except in the year in which the then existing Revolving Termination Date shall occur, in which case such written notice shall be delivered by the Lenders no later than fifteen (15) days prior to the then existing Revolving Termination Date) (such date, the “Consent Date”), advise the Administrative Agent in writing of its desire to extend (any such Lender, an “Extending Lender”) or not to so extend (any such Lender, a “Non-Extending Lender”) such date. Any Lender that does not advise the Administrative Agent by the Consent Date shall be deemed to be a Non-Extending Lender. No Lender shall be under any obligation or commitment to extend the then existing Revolving Termination Date. The election of any Lender to agree to such extension shall not obligate any other Lender to agree to such extension.

(b) On the Consent Date, if Lenders holding Commitments that aggregate more than 50% of the Total Revolving Commitments (or, if the Revolving Commitments have expired or been terminated, the Total Revolving Extensions of Credit then outstanding) shall have agreed to such extension, then the then existing Revolving Termination Date applicable to the Extending

Lenders shall be extended to the date that is one (1) year after the then existing Revolving Termination Date. All Revolving Extensions of Credit of each Non-Extending Lender shall be subject to the then existing Revolving Termination Date, without giving effect to such extension (such date, the “Prior Termination Date”). In the event of an extension of the then existing Revolving Termination Date pursuant to this Section 2.24(b), the Borrower shall have the right, at its own expense, to solicit commitments from existing Lenders and/or other banks or financial institutions reasonably acceptable to the Administrative Agent (each, an “Eligible Replacement Lender”) to replace the Revolving Commitment of any Non-Extending Lenders for the remaining duration of this Agreement. Any Eligible Replacement Lender (if not already a Lender hereunder) shall become a party to this Agreement as a Lender by delivering an executed Joinder Agreement to the Administrative Agent and the Borrower. The Revolving Commitment of each Non-Extending Lender shall terminate on the Prior Termination Date, all Revolving Extensions of Credit and other amounts payable hereunder to such Non-Extending Lenders shall be subject to the Prior Termination Date and, to the extent such Non-Extending Lender’s Revolving Commitment is not replaced as provided above, the Revolving Commitments hereunder shall be reduced by the amount of the Revolving Commitment of each such Non-Extending Lender so terminated on the Prior Termination Date. Notwithstanding anything to the contrary in this Section 2.24(b), the Revolving Termination Date shall not be extended unless the aggregate Revolving Commitments of the Extending Lenders and any Eligible Replacement Lenders joining this Agreement pursuant to this Section 2.24(b) are greater than or equal to the aggregate amount of the Revolving Extensions of Credit as of each Prior Termination Date.

(c) An extension of the Revolving Termination Date pursuant to this Section 2.24(c) shall only become effective upon the receipt by the Administrative Agent of a certificate (the statements contained in which shall be true) of duly authorized officers of the Borrower stating that both before and after giving effect to such extension of the Revolving Termination Date, (i) no Default or Event of Default shall then exist or have occurred and be continuing and (ii) the other conditions set forth in Section 4.2 shall have been satisfied.

SECTION 3.

REPRESENTATIONS AND WARRANTIES

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Loans, the Borrower hereby represents and warrants to the Administrative Agent and each Lender that:

3.1 Financial Condition. The audited consolidated balance sheet of the Borrower as at December 31, 2010, and the related consolidated statements of income, retained earnings and cash flows for the fiscal year ended on such date, reported on by and accompanied by an unqualified report from Deloitte & Touche LLP, fairly present in all material respects the consolidated financial condition of the Borrower as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The unaudited consolidated balance sheet of the Borrower as at September 30, 2011, and the related unaudited consolidated statements of income, retained earnings and cash flows for the nine-month period ended on such date, fairly present in all material respects the consolidated financial condition of the Borrower as at such date, and the consolidated results of its operations and its consolidated

cash flows for the nine-month period then ended (subject to normal year end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein) except, in the case of unaudited financial statements, the absence of footnotes and subject to normal year end audit adjustments.

3.2 No Change. Since December 31, 2010, no event or condition has occurred or changed that has had or could reasonably be expected to have a Material Adverse Effect.

3.3 Existence; Compliance with Law. Each Group Member (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization except, in the case of any Subsidiary, to the extent that the failure to comply therewith could not reasonably be expected to have a Material Adverse Effect, (b) has the corporate power and authority, and the legal right, to own and operate its property, to lease the property it operates as lessee and to conduct the business in which it is currently engaged except, in the case of any Subsidiary, to the extent that the failure to comply therewith could not reasonably be expected to have a Material Adverse Effect, (c) is duly qualified as a foreign corporation and in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification except to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect and (d) is in compliance with all Requirements of Law except to the extent that such non-compliance, singly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

3.4 Power; Authorization; Enforceable Obligations. The Borrower has the corporate power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and to obtain extensions of credit hereunder. The Borrower has taken all necessary organizational action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and to authorize the extensions of credit on the terms and conditions of this Agreement. No authorization or approval of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the extensions of credit hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, other than any such consents, authorizations, filings and notices which have been obtained or made and are in full force and effect. Each Loan Document has been duly executed and delivered on behalf of the Borrower. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

3.5 No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any material Requirement of Law or any material Contractual Obligation of any of the Borrower or its Subsidiaries and will not result in, or require, the creation or imposition of any

Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation.

3.6 Litigation. No litigation, arbitration or administrative proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened (i) against the Borrower or any of its Subsidiaries to restrain the entry the Borrower into, the enforcement of or exercise of any rights by the Lenders or the Administrative Agent under, or the performance or compliance by the Borrower with any obligations under, this Agreement or the Notes or (ii) except as previously disclosed in the SEC Disclosure Documents, against the Borrower or any of its Subsidiaries which has had or would reasonably be expected to have a Material Adverse Effect.

3.7 No Default. No Default or Event of Default has occurred and is continuing.

3.8 Ownership of Property; Liens. Each Group Member has title in fee simple to, or a valid leasehold interest in, all its real property which is material to the operation of such Group Member’s business, and good title to, or a valid leasehold interest in, all its other property which is material to the operation of such Group Member’s business (except where the failure to have such title, a valid leasehold interest or other enforceable interest is not reasonably likely to have a Material Adverse Effect), and, in the case of the Borrower, none of such property is subject to any Lien except as permitted by Section 6.2.

3.9 Intellectual Property. Except as, either singly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect: (i) each Group Member owns, or is licensed to use, all Intellectual Property necessary for the conduct of its business as currently conducted; (ii) no material claim has been asserted and is pending by any Person challenging or questioning the use of any Intellectual Property or the validity or effectiveness of any Intellectual Property, nor does the Borrower know of any valid basis for any such claim and (iii) the use of Intellectual Property which is material to the operation of each Group Member’s business does not infringe on the rights of any Person in any material respect.

3.10 Taxes. Each Group Member has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all Taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all other Taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the relevant Group Member); no tax Lien has been filed (except as permitted under Section 6.2(c)), and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such Tax, fee or other charge (other than any such tax, fee or charge, the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the relevant Group Member).

3.11 Federal Regulations. No part of the proceeds of any Loans, and no other extensions of credit hereunder, will be used in any manner which violates Regulation U as now and from time to time hereafter in effect or for any purpose that violates the provisions of the

Regulations of the Board. If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U 1, as applicable, referred to in Regulation U. After application of the proceeds of all Loans and any purchases funded thereby, less than 25% of the assets of the Borrower and its Subsidiaries consist of “margin stock” (as defined in Regulation U).

3.12 ERISA. Neither a Reportable Event nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred during the five year period prior to the date on which this representation is made or deemed made with respect to any Plan, and, to the knowledge and belief of the Borrower, each Plan has complied in all material respects with the applicable provisions of ERISA and the Code except where non-compliance, either singly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. No termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by an amount that could reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a liability or loss under ERISA, and neither the Borrower nor any Commonly Controlled Entity would become subject to any liability or loss under ERISA if the Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made, in any case where, either singly or in the aggregate, the aggregate amount of loss or liability could not reasonably be expected to have a Material Adverse Effect.

3.13 Investment Company Act; Other Regulations. The Borrower is not an “investment company”, or a company “controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended. The Borrower is not subject to regulation under any Requirement of Law (other than Regulation X of the Board) that limits its ability to borrow Loans or obtain other Revolving Extensions of Credit under this Agreement.

3.14 Subsidiaries. As of the Closing Date (a) Schedule 3.14 sets forth the name and jurisdiction of incorporation of each Subsidiary of the Borrower and, as to each such Subsidiary, the percentage of each class of Capital Stock owned by the Borrower, and (b) except as set forth on Schedule 3.14, there are no outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments (other than stock performance grants granted to employees or directors and directors’ qualifying shares) of any nature relating to any Capital Stock of the Borrower or any of the Borrower’s Subsidiaries, except as created by the Loan Documents.

3.15 Use of Proceeds. The proceeds of the Loans shall be used to repay Indebtedness under the Existing Credit Agreements, to support the issuance of commercial paper by the Borrower, to fund Permitted Acquisitions and capital expenditures of the Borrower and its

Subsidiaries and to provide for ongoing working capital needs, and for general corporate purposes of the Borrower and the other Group Members.

3.16 Environmental Matters. Except (i) as may be disclosed on Schedule 3.16, or (ii) as, either singly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect:

(a) the facilities and properties owned, leased or operated by any of the Borrower or its Subsidiaries (the “Properties”) do not contain, and have not previously contained, any Materials of Environmental Concern in amounts or concentrations or under circumstances that constitute or constituted a violation of, or could give rise to liability under, any Environmental Law;

(b) none of the Borrower or its Subsidiaries has received or is aware of any notice of violation, alleged violation, non-compliance, liability or potential liability regarding environmental matters or compliance with Environmental Laws with regard to any of the Properties or the business operated by any of them (the “Business”), nor does the Borrower have knowledge or reason to believe that any such notice will be received or is being threatened;

(c) Materials of Environmental Concern have not been transported or disposed of from the Properties in violation of, or in a manner or to a location that could give rise to liability under, any Environmental Law, nor have any Materials of Environmental Concern been generated, treated, stored or disposed of at, on or under any of the Properties in violation of, or in a manner that could give rise to liability under, any applicable Environmental Law;

(d) no judicial proceeding or governmental or administrative action is pending or, to the knowledge of the Borrower, threatened, under any Environmental Law to which any of the Borrower or its Subsidiaries is or will be named as a party with respect to the Properties or the Business, nor are there any consent decrees or other decrees, consent orders, administrative orders or other orders, or other administrative or judicial requirements outstanding under any Environmental Law with respect to the Properties or the Business;

(e) there has been no release or threat of release of Materials of Environmental Concern at or from the Properties, or arising from or related to the operations in connection with the Properties or otherwise in connection with the Business, in violation of or in amounts or in a manner that could give rise to liability under Environmental Laws;

(f) the Properties and all operations at the Properties are in compliance, and have in the last five years been in compliance, with all applicable Environmental Laws, and there is no contamination at, under or about the Properties or violation of any Environmental Law with respect to the Properties or the Business; and

(g) no Group Member has assumed any liability of any other Person under Environmental Laws.

3.17 Full Disclosure. All factual information heretofore or contemporaneously furnished by or on behalf of the Borrower in writing to the Administrative Agent or the Lenders for purposes of or in connection with this Agreement or any transaction contemplated hereby is,

when taken as a whole, true and accurate in every material respect on the date as of which such information is dated or certified and as of the date of execution and delivery of this Agreement by the Lenders, and such information, when taken as a whole, is not incomplete by omitting to state any material fact necessary to make such information not misleading. All other such factual information hereafter furnished by or on behalf of the Borrower will be, when taken as a whole, true and accurate in every material respect on the date as of which such information is dated or certified, and such information, when taken as a whole, shall not be incomplete by omitting to state any material fact necessary to make such information not misleading.

3.18 Solvency. The Borrower is, and after giving effect to the incurrence of all Obligations being incurred in connection herewith, will be and will continue to be, Solvent.

3.19 Status of Loans. The obligations of the Borrower in respect of the Loans constitute senior, unsubordinated, unsecured, direct obligations of the Borrower and rank pari passu with the Borrower’s other senior, unsubordinated, unsecured obligations.

3.20 OFAC. The Borrower (i) is not a person whose property or interest in property is blocked or subject to blocking pursuant to Section 1 of Executive Order 13224 of September 23, 2001 Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism (66 Fed.

5.4 Maintenance of Existence; Compliance. (a) (i) Preserve, renew and keep in full force and effect its organizational existence except, in the case of any Subsidiary, to the extent that the failure to comply therewith could not reasonably be expected to have a Material Adverse Effect and (ii) take all reasonable action to maintain all rights, privileges and franchises necessary or desirable in the normal conduct of its business, except, in each case, as otherwise permitted by Section 6.3 and except, in the case of clause (ii) above, to the extent that failure to do so could not reasonably be expected to have a Material Adverse Effect; and (b) comply with all Contractual Obligations and Requirements of Law except to the extent that failure to comply therewith would not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

5.5 Maintenance of Property; Insurance. (a) Keep all property useful and necessary in its business in good working order and condition, ordinary wear and tear excepted, except where the failure to maintain such property would not reasonably be expected to have a Material Adverse Effect and (b) maintain insurance (either with financially sound insurance companies or through self-insurance) on all its property in at least such amounts and against at least such risks (but including in any event public liability and business interruption) as are usually insured against in the same general area by companies engaged in the same or a similar business.

5.6 Inspection of Property; Books and Records; Discussions. (a) Keep proper books of records and account in respect of the Borrower and its Subsidiaries in which full, true and correct entries (in all material respects when taken as a whole) in conformity with GAAP and all Requirements of Law shall be made of all dealings and transactions in relation to their business and activities and (b) for purposes of confirming compliance with the Loan Documents or after the occurrence and during the continuance of an Event of Default, upon reasonable notice from the Administrative Agent or the Required Lenders, the Borrower will permit the Lenders (and such Persons as any Lender may designate) during normal business hours to visit and inspect, under the Borrower’s guidance, any of the properties of the Group Members, to examine all of their books of account, records, reports and other papers, to make copies and extracts therefrom, and to discuss their respective affairs, finances and accounts with their respective officers, employees and with their independent public accountants (and by this provision the Borrower authorizes such accountants to discuss with the Lenders (and such

Persons as any Lender may designate) the finances and affairs of the Group Members) all at such reasonable times and as often as may be reasonably requested; provided, however, that except upon the occurrence and during the continuation of any Default or Event of Default, not more than one such visit and inspection may be conducted in any twelve month period. Prior to the occurrence of an Event of Default, the Borrower shall only be required to pay the costs and expenses of professionals retained by the Administrative Agent in connection with any such visit or inspection. So long as no Event of Default has occurred and is continuing, the Borrower shall be obligated to pay all reasonable costs and expenses incurred by the Administrative Agent and the Lenders in connection with such visitations and inspections no more than once annually. The Borrower shall receive advance notice of any proposed discussion with such accountants and shall have the right to participate therein.

(a) the occurrence of any Default or Event of Default;

(b) to the extent not previously disclosed in the SEC Disclosure Documents, the following events, at such time as a Responsible Officer has knowledge thereof; any (i) default or event of default under any material Contractual Obligation of the Borrower or any of its Subsidiaries or (ii) litigation or governmental proceeding that may exist at any time between the Borrower or any of its Subsidiaries and any Governmental Authority, and (iii) the occurrence of any Reportable Event with respect to any Plan, a failure to make any required contribution to a Plan, the creation of any Lien in favor of the PBGC or a Plan or any withdrawal from, or the termination, Reorganization or Insolvency of, any Multiemployer Plan or the institution of proceedings or the taking of any other action by the PBGC or the Borrower or any Commonly Controlled Entity or any Multiemployer Plan with respect to the withdrawal from, or the termination, Reorganization or Insolvency of, any Plan, that in any of the foregoing cases (i) through (iii) singly or in the aggregate, could reasonably be expected to result in liabilities, losses or claims to the Group Members in an aggregate amount in excess of $50,000,000; and

(c) any adverse change in or downgrade of, or withdrawal or suspension of, the Moody’s Rating or the S&P Rating of which the Borrower has received written notification or of which the Borrower becomes aware of the public announcement thereof.

Each notice pursuant to this Section 5.7 shall be accompanied by a statement of a Responsible Officer setting forth details of the occurrence referred to therein and stating what action the relevant Group Member proposes to take with respect thereto.

(b) Conduct and complete in all material respects all investigations, studies, sampling and testing, and all remedial, removal and other actions required under Environmental Laws and comply in a timely manner in all material respects with all lawful orders and directives of all Governmental Authorities regarding Environmental Laws except where such non-compliance would not reasonably be expected to have a Material Adverse Effect.

5.9 OFAC, PATRIOT Act Compliance. The Borrower will, and will cause each Group Member to, (i) refrain from doing business in a Sanctioned Country or with a Sanctioned Person in violation of the economic sanctions of the United States administered by OFAC, and (ii) provide, to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the PATRIOT Act.

SECTION 6.

SECTION 8.

THE AGENT

8.1 Appointment. Each Lender hereby irrevocably designates and appoints the Administrative Agent as the Agent of such Lender under this Agreement and the other Loan Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, 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 the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, 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. Except as set forth in Section 8.9, the provisions of this Section 8 are solely for the benefit of the Administrative Agent and the Lenders, the Borrower shall have no rights as a third party beneficiary of any of such provisions.

8.2 Delegation of Duties. The Administrative Agent may execute any of its 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. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys in fact selected by it with reasonable care.

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

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

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

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

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 7 and 9.1) or (ii) in the absence of its own gross negligence or willful misconduct.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Section 4 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

8.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order 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 (including counsel to the Borrower), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with 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 Required Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that 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 and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all 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 Loans.

8.5 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 unless the Administrative Agent has received notice from a Lender or the Borrower 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 the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent shall have received such directions, 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 in the best interests of the Lenders.

8.6 Non Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that neither the Agents nor any of their respective officers, directors, employees, agents, attorneys in fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of the Borrower or any

affiliate of the Borrower, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents 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 Borrower and its affiliates and made its own decision to make its Loans 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 Borrower and its affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or any affiliate of the Borrower that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys in fact or affiliates.

8.7 Indemnification. To the extent that the Borrower for any reason fails to pay any amount required under Section 9.5 to be paid by it to the Administrative Agent (or any sub-agent thereof) or any other Indemnitee, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent) or such other Indemnitee, as the case may be, such Lender’s proportion (based on the percentages as used in determining the Required Lenders as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) or against any other Indemnitee of any of the foregoing acting for the Administrative Agent (or any such sub-agent) in connection with such capacity.

8.8 Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though such Agent were not an Agent. With respect to its Loans made or renewed by it, each 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 each Agent in its individual capacity.

8.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon ten days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 7(a) or Section 7(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent

effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is ten 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 assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 8 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 and the other Loan Documents.

8.10 Co-Documentation Agents, Co-Syndication Agents and Joint Arrangers. None of the Co-Documentation Agents, the Co-Syndication Agents or the Joint Arrangers shall have any duties or responsibilities hereunder in its capacity as such.

SECTION 9.

9.1 Amendments and Waivers. Neither this Agreement, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 9.1. The Required Lenders and the Borrower (any required response to the matters described in clauses (a) or (b) of this Section 9.1 not to be unreasonably delayed by any party) party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Administrative Agent and the Borrower (any required response to the matters described in clauses (a) or (b) of this Section 9.1 not to be unreasonably delayed by any party) party to the relevant Loan Document may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Borrower hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) forgive any principal amount or extend the final scheduled date of maturity of any Loan beyond the Revolving Termination Date, reduce the stated rate of any interest or fee payable hereunder or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Lender’s Revolving Commitment, in each case without the written consent of each Lender directly affected thereby; (ii) eliminate or reduce the voting rights of any Lender under this Section 9.1 without the written consent of such Lender; (iii) reduce any percentage specified in the definition of Required Lenders or consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan Documents without the written consent of all Lenders; (iv) amend, modify or waive any provision of Section 8 without the written consent of the Administrative Agent; (v) amend, modify or waive any provision of Section 2.3 or 2.3(d)

without the written consent of the Swingline Lender, or (vi) modify or waive Sections 2.1(c) or 2.15 or the pro rata treatment of any Lender without the written consent of all Lenders directly affected thereby. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Borrower, the Lenders, the Administrative Agent and all future holders of the Loans. In the case of any waiver, the Borrower, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. Notwithstanding anything to the contrary herein, (1) no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders of each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender and (2) if the Administrative Agent and the Borrower shall have jointly identified (each in its sole discretion) an obvious error or omission of a technical or immaterial nature, in each case, in any provision of the Loan Documents, then the Administrative Agent and the Borrower shall be permitted to amend such provision and such amendment shall become effective without any further action or consent of any other party to any Loan Document if the same is not objected to in writing by the Required Lenders within five Business Days following the posting of such amendment to the Lenders.

the address set forth in the Administrative Questionnaire or the Assignment and Acceptance Agreement executed by such Lender

provided that any notice, request or demand to or upon the Administrative Agent or the Lenders shall not be effective until received.

(b) The Borrower agrees that the Administrative Agent may make the Communications (as defined below) available to the Lenders by posting the Communications on SyndTrak or a substantially similar electronic transmission system (the “Platform”). THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” The Agent Parties (as defined below) do not warrant the adequacy of the platform and expressly disclaim liability for errors or

omissions in the communications effected thereby (the “Communications”). No warranty of any kind, express, implied or statutory, including any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom from viruses or other code defects, is made by any Agent Party in connection with the Communications or the Platform. In no event shall the Administrative Agent or any of its Related Parties (collectively, the “Agent Parties”) have any liability to the Borrower, any Lender or any other Person or entity for damages of any kind, including direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of the Borrower’s or the Administrative Agent’s transmission of Communications through the Platform other than for direct or actual damages resulting from the gross negligence or willful misconduct of such Agent Party as determined by a final and nonappealable judgment of a court of competent jurisdiction.

Information required to be delivered pursuant to Sections 5.1, 5.2(b)(ii) and 5.2(c) shall be deemed to have been delivered on the date on which the Borrower provides notice to the Administrative Agent (which notice the Administrative Agent shall promptly provide to the Lenders) that such information has been posted on the SEC website on the Internet at sec.gov/edaux/searches.htm, on the Borrower’s IntraLinks site at intralinks.com or at another website identified in such notice and accessible by the Lenders without charge.

9.3 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 or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

9.4 Survival of Representations and Warranties. All representations and warranties made hereunder, 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 and for a period of one year after the indefeasible payment in full of all Obligations and the termination of this Agreement and the other Loan Documents.

9.5 Payment of Expenses and Taxes; Indemnity; Damage Waiver. The Borrower agrees (a) to pay or reimburse the Arrangers and the Administrative Agent for all of their reasonable out of pocket costs and expenses incurred in connection with the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including the reasonable fees and disbursements of counsel to the Administrative Agent and filing and recording fees and expenses, with statements with respect to the foregoing to be submitted to the Borrower prior to the Closing Date (in the case of amounts to be paid on the Closing Date) and from time to time thereafter on a quarterly basis or such other periodic basis as the Administrative Agent shall deem appropriate, (b) to pay or reimburse each Lender and the Administrative Agent for all its reasonable out-of-pocket costs and expenses incurred in connection with the enforcement or preservation of any rights under

this Agreement, the other Loan Documents and any such other documents, including the reasonable and out-of-pocket fees and disbursements of counsel (but limited in the case of fees and disbursements of counsel to one counsel for the Administrative Agent and one additional counsel to the Lenders (and appropriate specialty and local counsel for each); provided, however, that in the event any Lender or its counsel reasonably determines that it would create an actual or potential conflict of interest to not have individual counsel, such Lender may engage and be reimbursed for its own counsel in accordance with the foregoing), (c) to pay, indemnify, and hold each Lender and the Administrative Agent harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, Other Taxes, if any, that may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify, and hold each Lender, each Arranger, the Administrative Agent and their respective officers, directors, employees, Affiliates, agents and controlling persons (each, an “Indemnitee”) harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including any of the foregoing relating to the use of proceeds of the Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of any Group Member or any of the Properties and the reasonable fees and expenses of legal counsel in connection with claims, actions or proceedings by any Indemnitee against the Borrower under any Loan Document (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”); provided, that the Borrower shall have no obligation hereunder to any Indemnitee (i) with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee or (ii) in any proceeding that does not involve an act or alleged act or omission or alleged omission by the Borrower or any of the Borrower’s affiliates and is brought by an indemnitee against another indemnitee; provided, that notwithstanding this clause (ii), any party to such proceeding that was acting in its capacity as an agent, an arranger, a bookrunner or in another agency capacity with respect to the Facility and the transactions contemplated by this Agreement and the other Loan Documents shall be indemnified in its capacity as such in all such proceedings. To the maximum extent permitted by applicable law, each party to this Agreement agrees that it shall not assert, and hereby waives, any right or claim against any other party to this Agreement, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated by this Agreement or any other Loan Document, any Loan or the use of the proceeds thereof; provided, however, that Indemnified Liabilities arising out of a claim by any Person against an Indemnitee shall be considered direct damages for purposes of this Section 9.5, even if such claim may constitute consequential damages with respect to the Person asserting such claim. No Indemnitee shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed to such unintended recipients by such Indemnitee through telecommunications, electronic or other information transmission systems (including

Intralinks, SyndTrak or similar systems) in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby other than for direct or actual damages resulting from the gross negligence or willful misconduct of such Indemnitee as determined by a final and nonappealable judgment of a court of competent jurisdiction. Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section 9.5 shall be payable not later than ten days after written demand therefor. Statements payable by the Borrower pursuant to this Section 9.5 shall be submitted to the Treasurer, AGL Resources Inc. (Telephone No. 404/584-3582) (Telecopy No. 404/584-3589), at the address of the Borrower set forth in Section 9.2, or to such other Person or address as may be hereafter designated by the Borrower in a written notice to the Administrative Agent. The agreements in this Section 9.5 shall survive repayment of the Loans and all other amounts payable hereunder. Notwithstanding the foregoing, Indemnified Liabilities under clause (d) of this Section 9.5 shall not include any Taxes, other than any Taxes that represent losses, claims or damages arising solely from any non-Tax claim.

9.6 Successors and Assigns; Participations and Assignments.

(a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Administrative Agent, all future holders of the Loans and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender.

(b) Any Lender other than any Conduit Lender may, without the consent of the Borrower, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a “Participant”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan for all purposes under this Agreement and the other Loan Documents, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Loans or any fees payable hereunder or postpone the date of the final maturity of the Loans, in each case to the extent subject to such participation. The Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff 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, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 9.7(a) as fully as if it were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.16, 2.17 and 9.5 with respect to its participation in the Commitments and the Loans outstanding from time to time as if it was a Lender; provided that, in the case of Section 2.17, such Participant shall have complied with the requirements of said Section and provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred. Each Lender selling participations (other than the sale of participations to a Lender Affiliate) shall use its commercially reasonable efforts to provide prompt notice to the Borrower and the Administrative Agent of such participations and of the identity of the purchasers of such participations; provided that no delay or failure of such notice to be so given shall affect the validity of such sale. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.

(c) Any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000, in the case of any assignment of a Loan, unless each of the Administrative Agent and the Borrower otherwise consents to such lesser amount, (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned and (iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire. Upon (i) the execution and delivery of the Assignment and Acceptance by the assigning Lender (the “Assignor”) and assignee Lender (the “Assignee”), (ii) acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, (iii) consent thereof from the Borrower to the extent required pursuant to this paragraph (c) and (iv) if such assignee Lender is a Non-U.S. Lender, compliance by such Person with Section 2.15(d), from and after the effective date

specified in each Assignment and Acceptance, the Eligible 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 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 of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 2.15, 2.16 and 9.5. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(d) Notwithstanding anything to the contrary contained in this Agreement, no assignment shall be made (i) to the Borrower or any of its Subsidiaries or Affiliates, or (ii) to any Defaulting Lender or any of its Subsidiaries, or any Person, who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii) of this Section 9.6(d).

(e) In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment (but not including the Borrower) shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Swingline Loans in accordance with its Revolving Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

(f) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and the principal and stated interest amounts of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Loans and any Notes evidencing the Loans recorded therein for all purposes of this Agreement. In addition, the Administrative Agent shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect

thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance, and thereupon one or more new Notes shall be issued to the designated Assignee.

(g) Upon its receipt of an Assignment and Acceptance executed by an Assignor, an Assignee and any other Person whose consent is required by Section 9.6(c), together with payment to the Administrative Agent of a registration and processing fee of $3,500, the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) record the information contained therein in the Register on the effective date determined pursuant thereto.

(h) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section 9.6 concerning assignments relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests, including any pledge or assignment by a Lender to any Federal Reserve Bank in accordance with applicable law.

(i) The Borrower, upon receipt of written notice from the relevant Lender, agrees to issue Notes to any Lender requiring Notes to facilitate transactions of the type described in paragraph (f) above.

(j) Each of the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance.

9.7 Adjustments; Set off.

(a) Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or to the Lenders under the Facility, if any Lender (a “Benefited Lender”) shall, at any time after the Loans and other amounts payable hereunder shall immediately become due and payable pursuant to Section 7, receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set off, pursuant to events or proceedings of the nature referred to in Section 7(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, 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.

(b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, unless they have agreed to the contrary, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower, as the case may be; provided, that in the event that any Defaulting Lender shall exercise any such right of setoff hereunder, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.23 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders (including the Swingline Lender), and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the obligations owing to such Defaulting Lender as to which it exercised such right of setoff. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application.

9.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent.

9.9 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 9.9, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent or the Swingline Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

9.10 Integration. This Agreement and the other Loan Documents represent the entire agreement of the Borrower, the Administrative Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents.

9.11 GOVERNING LAW. 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.

9.12 Submission To Jurisdiction; Waivers. The Borrower hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the exclusive general jurisdiction of the courts of the State of New York located in the Borough of Manhattan in the city of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the Borrower, as the case may be at its address set forth in Section 9.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto; and

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction.

9.13 Acknowledgements. The Borrower 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 nor any Lender has any fiduciary relationship with or duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Borrower and the Lenders.

9.14 Confidentiality. Each of the Administrative Agent and each Lender agrees to keep confidential all non-public information provided to it by the Borrower pursuant to this Agreement that is designated by the Borrower as confidential; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the

For additional discussion and detailed description of MGP matters, including regulatory recovery mechanism, see Nicor Inc.’s and the Borrower’s 2010 10-K filing and 10-Q filing for the quarter ended September 30, 2011.

The Borrower has received inquiries from the Illinois Attorney General, the U.S. Environmental Protection Agency and the Illinois Environmental Protection Agency regarding several incidents where liquids containing PCBs traveled through the Borrower’s equipment into several customers’ homes in Park Ridge, IL.

Claims have been made relating to damage and/or injury allegedly caused by the removal of mercury regulators from the homes of the Borrower’s customers.

The Borrower has received notice of a potential citizens’ suit for damage related to deprivation of use of a waterway for kayaking due to contamination resulting from a former manufactured gas plant.

The Borrower owned a multi-use reporting facility at 715 Parkwood Avenue in Romeoville, Illinois. On September 9, 2010, an Enbridge pipeline located on Parkwood Avenue in the front of the Borrower’s facility ruptured resulting in 250,000 gallons of oil leaking into the surrounding area and the Borrower’s facility. On December 22, 2010, the Borrower transferred the facility and all related environmental liabilities to Enbridge under a confidential settlement agreement. Enbridge is remediating the oil leak under the U.S. EPA’s oversight.

The Borrower also owns a multi-use reporting facility at 750 North Elmhurst Road in Elk Grove Village, Illinois, at which soil is contaminated by petroleum products from a previously removed underground storage tank. The Borrower has not received any damage claim or violation notice regarding this contamination, and the Borrower intends to voluntarily remediate the contamination in early 2012.
