Each such notice must be received by the Administrative Agent not later than 11:00 a.m. (i) three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base Rate Committed Loans, and (ii) on the requested date of any Borrowing of Base Rate Committed Loans. Each Borrowing of, conversion or continuation of Committed Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Each Committed Loan Notice shall specify (i) whether the Borrower is requesting a Borrowing, a conversion of Committed Loans from one Type to the other, or a continuation of Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Committed Loans to be borrowed, converted or continued, (iv) the Type of Committed Loans to be borrowed or to which existing Committed Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect thereto.

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

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

(c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted only on the last day of an Interest Period for such Eurodollar Rate Loan. During the existence

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

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

Once an Auto-Renewal Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the L/C Issuer to permit the renewal of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date; provided, however, that the L/C Issuer shall not permit any such renewal if (A) the L/C Issuer has determined that it would have no obligation at such time to issue such Letter of Credit in its renewed form under the terms hereof (by reason of the provisions of Section 2.03(a)(ii) or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is two Business Days before the Nonrenewal Notice Date (1) from the Administrative Agent that the Required Lenders have elected not to permit such renewal or (2) from the Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 4.02 is not then satisfied.

(iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, the L/C Issuer will also deliver to the Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment. The Administrative Agent shall give the Lenders notice of the issuance of any Letter of Credit and any amendment thereto.

(i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the L/C Issuer shall notify the Borrower and the Administrative Agent thereof. Not later than 11:00 a.m. on the date of any payment by the L/C Issuer under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to the amount of such drawing. If the Borrower fails to so reimburse the L/C Issuer by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have requested a Committed Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.02 (other than the delivery of a Committed Loan Notice). Any notice given by the L/C Issuer or the Administrative Agent pursuant to this Section 2.03(c)(i) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

(ii) Each Lender (including the Lender acting as L/C Issuer) shall upon any notice pursuant to Section 2.03(c)(i) make funds available to the Administrative Agent for the account of the L/C Issuer at the Administrative Agent’s Office in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.03(c)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Committed Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the L/C Issuer.

(iii) With respect to any Unreimbursed Amount that is not fully refinanced by a Committed Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment to the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03.

(iv) Until each Lender funds its Committed Loan or L/C Advance pursuant to this Section 2.03(c) to reimburse the L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Pro Rata Share of such amount shall be solely for the account of the L/C Issuer.

(v) Each Lender’s obligation to make Committed Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section 2.03(c), shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the L/C Issuer, the Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Committed Loans pursuant to this Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other than delivery by the Borrower of a Committed Loan Notice). No such making of an L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse the L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit, together with interest as provided herein.

(vi) If any Lender fails to make available to the Administrative Agent for the account of the L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.03(c) by the time specified in Section 2.03(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the L/C Issuer at a rate per annum equal to the Federal Funds Rate from time to time in effect. A certificate of the L/C Issuer submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (vi) shall be conclusive absent manifest error.

(d) Repayment of Participations.

(i) At any time after the L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.03(c), if the Administrative Agent receives for the account of the L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether

directly from the Borrower or otherwise, including proceeds of Cash Collateral (as defined in Section 2.03(g)) applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

(ii) If any payment received by the Administrative Agent for the account of the L/C Issuer pursuant to Section 2.03(c)(i) is required to be returned under any of the circumstances described in Section 10.06 (including pursuant to any settlement entered into by the L/C Issuer in its discretion), each Lender shall pay to the Administrative Agent for the account of the L/C Issuer its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect.

(e) Obligations Absolute. The obligation of the Borrower to reimburse the L/C Issuer for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or any other agreement or instrument relating thereto;

(ii) the existence of any claim, counterclaim, set-off, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the L/C Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) any payment by the L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by the L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any Debtor Relief Law; or

(v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower.

The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the L/C Issuer. The Borrower shall be conclusively deemed to have waived any such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid.

(f) Role of L/C Issuer. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the L/C Issuer, any Agent-Related Person, nor any of the respective correspondents, participants or assignees of the L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Application. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the L/C Issuer, any Agent-Related Person, any Lender, nor any of the respective correspondents, participants or assignees of the L/C Issuer, shall be liable or responsible to the Borrower for any of the matters described in clauses (i) through (v) of Section 2.03(e); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if, as of the Letter of Credit Expiration Date, any Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, the Borrower shall immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations (in an amount equal to such Outstanding Amount determined as of the date of such L/C Borrowing or the Letter of Credit Expiration Date, as the case may be). For purposes hereof, “Cash Collateralize” means to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, as collateral for the L/C Obligations, cash or deposit account balances pursuant to documentation in form and substance satisfactory to the Administrative Agent and the L/C Issuer (which documents are hereby consented to by the Lenders). Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the L/C Issuer and the Lenders, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America.

(h) Applicability of ISP. Unless otherwise expressly agreed by the L/C Issuer and the Borrower when a Letter of Credit is issued, the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) (the “ISP”) shall apply to each standby Letter of Credit.

(i) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Pro Rata Share a Letter of Credit fee for each Letter of Credit equal to the Applicable Rate times the daily maximum amount available to be drawn under such Letter of Credit (whether or not such maximum amount is then in effect under such Letter of Credit).

Such Letter of Credit fees shall be computed on a quarterly basis in arrears. Such Letter of Credit fees shall be due and payable on the first Business Day after the end of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. If there is any change in the Applicable Rate during any quarter, the daily maximum amount of each Letter of Credit shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to each Letter of Credit in the amounts and at the times specified in the Fee Letter. In addition, the Borrower shall pay directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of the L/C Issuer relating to Letters of Credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

(k) Conflict with Letter of Credit Application. In the event of any conflict between the terms hereof and the terms of any Letter of Credit Application, the terms hereof shall control.

2.04 Swing Line Loans.

(a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.04, to make loans (each such loan, a “Swing Line Loan”) to the Borrower from time to time on any Business Day during the Availability Period in an aggregate amount not to exceed at any time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact that such Swing Line Loans, when aggregated with the Pro Rata Share of the Outstanding Amount of Committed Loans and L/C Obligations of the Lender acting as Swing Line Lender, may exceed the amount of such Lender’s Commitment; provided, however, that after giving effect to any Swing Line Loan, (i) the Total Outstandings shall not exceed the Aggregate Commitments, and (ii) the aggregate Outstanding Amount of the Committed Loans of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations, plus such Lender’s Pro Rata Share of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Commitment, and provided, further, that the Borrower shall not use the proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may borrow under this Section 2.04, prepay under Section 2.05, and reborrow under this Section 2.04. Each Swing Line Loan shall be a Base Rate Loan. Immediately upon the making of a Swing Line Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender a risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Pro Rata Share times the amount of such Swing Line Loan.

(b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the Borrower’s irrevocable notice to the Swing Line Lender and the Administrative Agent, which may be given by telephone. Each such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $100,000, and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice must be confirmed promptly by delivery to the Swing Line Lender and the Administrative Agent of a written Swing Line Loan Notice, appropriately completed and signed by a Responsible Officer of the Borrower. Promptly after receipt by the Swing Line Lender of any telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Swing Line Loan Notice and, if not, the Swing Line Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received notice (by telephone or in writing) from the

Administrative Agent (including at the request of any Lender) prior to 2:00 p.m. on the date of the proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the proviso to the first sentence of Section 2.04(a), or (B) that one or more of the applicable conditions specified in Article IV is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 3:00 p.m. on the borrowing date specified in such Swing Line Loan Notice, make the amount of its Swing Line Loan available to the Borrower.

(i) The Swing Line Lender at any time in its sole and absolute discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make a Base Rate Committed Loan in an amount equal to such Lender’s Pro Rata Share of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Committed Loan Notice for purposes hereof) and in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the Aggregate Commitments and the conditions set forth in Section 4.02. The Swing Line Lender shall furnish the Borrower with a copy of the applicable Committed Loan Notice promptly after delivering such notice to the Administrative Agent. Each Lender shall make an amount equal to its Pro Rata Share of the amount specified in such Committed Loan Notice available to the Administrative Agent in Same Day Funds for the account of the Swing Line Lender at the Administrative Agent’s Office for Dollar-denominated payments not later than 1:00 p.m. on the day specified in such Committed Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Lender that so makes funds available shall be deemed to have made a Base Rate Committed Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swing Line Lender.

(ii) If for any reason any Swing Line Loan cannot be refinanced by such a Committed Borrowing in accordance with Section 2.04(c)(i), the request for Base Rate Committed Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in the relevant Swing Line Loan and each Lender’s payment to the Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.04(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to the Administrative Agent for the account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.04(c) by the time specified in Section 2.04(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation. A certificate of the Swing Line Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Committed Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or

continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Committed Loans pursuant to this Section 2.04(c) is subject to the conditions set forth in Section 4.02. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swing Line Loans, together with interest as provided herein.

(d) Repayment of Participations.

(i) At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Pro Rata Share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) in the same funds as those received by the Swing Line Lender.

(ii) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to be returned by the Swing Line Lender under any of the circumstances described in Section 10.05 (including pursuant to any settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the Borrower for interest on the Swing Line Loans. Until each Lender funds its Base Rate Committed Loan or risk participation pursuant to this Section 2.04 to refinance such Lender’s Pro Rata Share of any Swing Line Loan, interest in respect of such Pro Rata Share shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. The Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender.

2.05 Prepayments.

(a) The Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Committed Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Administrative Agent not later than 11:00 a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate Loans and (B) on the date of prepayment of Base Rate Committed Loans; (ii) any prepayment of Eurodollar Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof, and (iii) any prepayment of Base Rate Committed Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the Type(s) of Committed Loans to be prepaid. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s Pro Rata Share of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05. Each such prepayment shall be applied to the Committed Loans of the Lenders in accordance with their respective Pro Rata Shares.

(b) The Borrower may, upon notice to the Swing Line Lender (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Swing Line Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment, and (ii) any such prepayment shall be in a minimum principal amount of $100,000. Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Company, the Company shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

(c) If for any reason the Total Outstandings at any time exceed the Aggregate Commitments then in effect, the Borrower shall immediately prepay Loans and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess; provided, however, that the Borrower shall not be required to Cash Collateralize the L/C Obligations pursuant to this Section 2.05(b) unless after the prepayment in full of the Loans, the Total Outstandings exceed the Aggregate Commitments then in effect.

2.06 Termination or Reduction of Commitments. The Borrower may, upon notice to the Administrative Agent, terminate the Aggregate Commitments, or from time to time permanently reduce the Aggregate Commitments; provided that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m. three Business Days prior to the date of termination or reduction, (ii) any such partial reduction shall be in an aggregate amount of $10,000,000 or any whole multiple of $1,000,000 in excess thereof, (iii) the Borrower shall not terminate or reduce the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments hereunder, the Total Outstandings would exceed the Aggregate Commitments, and (iv) if, after giving effect to any reduction of the Aggregate Commitments, the Letter of Credit Sublimit or the Swing Line Sublimit exceeds the amount of the Aggregate Commitments, such Letter of Credit Sublimit or such Swing Line Sublimit shall be automatically reduced by the amount of such excess. The Administrative Agent will promptly notify the Lenders of any such notice of termination or reduction of the Aggregate Commitments. Any reduction of the Aggregate Commitments shall be applied to the Commitment of each Lender according to its Pro Rata Share. All facility and utilization fees accrued until the effective date of any termination of the Aggregate Commitments shall be paid on the effective date of such termination.

2.07 Repayment of Loans.

(a) The Borrower shall repay to the Lenders on the Maturity Date the aggregate principal amount of Committed Loans outstanding on such date.

(b) The Borrower shall repay each Swing Line Loan on the earlier to occur of (i) the date ten Business Days after such Swing Line Loan is made and (ii) the Maturity Date.

2.08 Interest.

(a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate; (ii) each Base Rate Committed Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate and (iii) each Swing Line Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate.

(b) If any amount payable by the Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the

Default Rate to the fullest extent permitted by applicable Laws. Furthermore, while any Event of Default exists, the Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws. Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law.

2.09 Fees.

(a) Facility Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Pro Rata Share, a facility fee equal to the Applicable Rate times the actual daily amount of the Aggregate Commitments (or, if the Aggregate Commitments have terminated, on the Outstanding Amount of all Committed Loans, Swing Line Loans, and L/C Obligations), regardless of usage. The facility fee shall accrue at all times during the Availability Period (and thereafter so long as any Committed Loans, Swing Line Loans, or L/C Obligations remain outstanding), including at any time during which one or more of the conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the Maturity Date (and, if applicable, thereafter on demand). The facility fee shall be calculated quarterly in arrears, and if there is any change in the Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(b) Utilization Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Pro Rata Share, a utilization fee equal to the Applicable Rate times the Total Outstandings on each day that the Total Outstandings exceed 50% of the actual daily amount of the Aggregate Commitments. The utilization fee shall be due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on the Maturity Date. The utilization fee shall be calculated quarterly in arrears and if there is any change in the Applicable Rate during any quarter, the daily amount shall be computed and multiplied by the Applicable Rate for each period during which such Applicable Rate was in effect. The utilization fee shall accrue at all times, including at any time during which one or more of the conditions in Article IV is not met.

(i) The Borrower shall pay to each Arranger and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in the Fee Letters. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

(ii) The Borrower shall pay to the Lenders such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

2.10 Computation of Interest and Fees. All computations of interest for Base Rate Loans when the Base Rate is determined by Bank of America’s “prime rate” shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall

accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.12(a), bear interest for one day.

2.11 Evidence of Debt.

(a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be prima facie evidence of the amount of the Credit Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto.

(b) In addition to the accounts and records referred to in subsection (a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swing Line Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.12 Payments Generally.

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

(b) If any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

(c) (i) Unless the Borrower has notified the Administrative Agent, prior to the date any payment is required to be made by it to the Administrative Agent or the L/C Issuer hereunder, that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then each of the Lenders or the L/C Issuer, as the case may be, shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender or the L/C Issuer in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender or the L/C Issuer to the date such

amount is repaid to the Administrative Agent in immediately available funds at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(ii) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurodollar Rate Loans (or, in the case of any Borrowing of Base Rate Loans, prior to 12:00 noon on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of Base Rate Loans, that such Lender has made such share available in accordance with and at the time required by Section 2.02) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (B) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Committed Loan included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

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

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

(e) The obligations of the Lenders hereunder to make Committed Loans and to fund participations in Letters of Credit and Swing Line Loans are several and not joint. The failure of any Lender to make any Committed Loan, to fund any such participation or to make any payment under Sections 10.4 or 10.5 on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Committed Loan, purchase its participation or make its payment under Sections 10.4 or 10.5.

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

2.13 Sharing of Payments. If, other than as expressly provided elsewhere herein, any Lender shall obtain on account of the Committed Loans made by it, or the participations in L/C Obligations or in Swing Line Loans held by it, any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) in excess of its ratable share (or other share contemplated hereunder)

thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Committed Loans made by them, and/or such subparticipations in the participations in L/C Obligations and Swing Line Loans held by them, as the case may be, as shall be necessary to cause such purchasing Lender to share the excess payment in respect of such Loans or such participations, as the case may be, pro rata with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender under any of the circumstances described in Section 10.06 (including pursuant to any settlement entered into by the purchasing Lender in its discretion), such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered, without further interest thereon. The Borrower agrees that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off, but subject to Section 10.09) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this Section and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this Section shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

2.14 Extension of Stated Maturity Date.

(a) Without further action by or consent from the Lenders, the Stated Maturity Date shall be extended to August 10, 2010 (or, if such date is not a Eurodollar Business Day, the next preceding Eurodollar Business Day) if the following requirements are satisfied: on or before July 10, 2006, the Borrower shall have provided to the Administrative Agent the following, in form and substance satisfactory to the Administrative Agent (i) a copy of the securities certificate registered with the Pennsylvania Public Utility Commission (the “Securities Certificate”) and of the order of the Pennsylvania Public Utility Commission approving the Borrower’s incurring indebtedness hereunder with a maturity date of August 10, 2010, (ii) an opinion of counsel to the Borrower (which may be internal counsel) stating that (A) the Securities Certificate has been registered with the Pennsylvania Public Utility Commission in accordance with Chapter 19 of the Pennsylvania Public Utility Code and by virtue of such registration, authorizes the Borrower to incur indebtedness hereunder with a maturity date of August 10, 2010, and (B) no other Authorizations are required by the Pennsylvania Public Utility Commission or by the PUC in any other state identified by the Borrower as being a state in which the Borrower is subject to regulation by a PUC and (iii) copies of corporate resolutions certified by the Secretary or Assistant Secretary of the Borrower, or such other evidence as may be satisfactory to the Administrative Agent, demonstrating that Borrower’s incurrence of indebtedness hereunder with a maturity date of August 10, 2010 has been duly authorized by all necessary corporate action, together with an opinion of counsel to the Borrower (which may be internal counsel) to such effect. The Administrative Agent shall promptly notify the Lenders when the foregoing conditions have been satisfied, and the extension shall be effective as of the date of such notice.

(b) Not earlier than 60 days prior to, nor later than 30 days prior to, each of the first two anniversaries of the Closing Date, the Borrower may, upon notice to the Administrative Agent (who shall promptly notify the Lenders), request a one year extension of the then current Stated Maturity Date. Within 15 days of delivery of such notice, each Lender shall notify the Administrative Agent whether or not it consents to such extension (which consent may be given or withheld in such Lender’s sole and absolute discretion). Any Lender not responding within the above time period shall be deemed not to have consented to such extension. The Administrative Agent shall promptly notify the Borrower and the

Lenders of the Lenders’ responses. If any Lender declines, or is deemed to have declined, to consent to such extension (a “Declining Lender”), the Borrower may cause any such Declining Lender to be removed or replaced as a Lender pursuant to Section 10.16.

Only if Lenders holding at least 51% of the Commitments (calculated prior to giving effect to any removals and/or replacements of Lenders permitted herein) (the “Consenting Lenders”) have consented to an extension requested pursuant to this Section 2.14(b), the Stated Maturity Date shall be extended, with respect only to the Consenting Lenders and any Lender replacing a Declining Lender pursuant to Section 10.16. If so extended, the Stated Maturity Date, as to the Consenting Lenders and each Lender replacing a Declining Lender pursuant to Section 10.16, shall be extended to the date falling one year after the existing Stated Maturity Date (except that if such date is not a Business Day, such Stated Maturity Date, as so extended, shall be the next preceding Business Day); provided, however, that the pre-existing Stated Maturity Date shall remain in effect with respect to any Declining Lender that is not replaced. The Administrative Agent and the Borrower shall promptly confirm to the Lenders such extension, and the Administrative Agent shall distribute an amended Schedule 2.01 (which shall be deemed incorporated into this Agreement), to reflect any changes in Lenders and their respective Commitments.

As a condition precedent to such extension, the Borrower shall have provided to the Administrative Agent the following, in form and substance satisfactory to the Administrative Agent (i) copies of corporate resolutions certified by the Secretary or Assistant Secretary of the Borrower, or such other evidence as may be satisfactory to the Administrative Agent, demonstrating that Borrower’s incurrence of indebtedness hereunder with a maturity date of the Stated Maturity Date, as extended pursuant to this Section 2.14(b), has been duly authorized by all necessary corporate action, together with an opinion of counsel to the Borrower (which may be internal counsel) to such effect, (ii) a certificate (in sufficient copies for each Lender), signed by a Responsible Officer of the Borrower certifying that, (A) before and after giving effect to such extension, the representations and warranties contained in Article V (including without limitation the representation and warranties set forth in Sections 5.04(c) and 5.05) and the other Loan Documents are true and correct on and as of the date thereof, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.14(b), the representations and warranties contained in subsections (a) and (b) of Section 5.04 shall be deemed to refer to the most recent statements furnished pursuant to subsections (a) and (b), respectively, of Section 6.01, and (B) no Default or Event of Default exists, (iii) a copy of the securities certificate registered with the Pennsylvania Public Utility Commission and of the order of the Pennsylvania Public Utility Commission approving the Borrower’s incurring indebtedness hereunder with a maturity date of the Stated Maturity Date, as extended pursuant to this Section 2.14(b), and (iv) an opinion of counsel to the Borrower (which may be internal counsel) stating that (A) such securities certificate has been registered with the Pennsylvania Public Utility Commission in accordance with Chapter 19 of the Pennsylvania Public Utility Code and by virtue of such registration, authorizes the Borrower to incur indebtedness hereunder with a maturity date of the Stated Maturity Date, as extended pursuant to this Section 2.14(b), and (B) no other Authorizations are required by the Pennsylvania Public Utility Commission or by the PUC in any other state identified by the Borrower as being a state in which the Borrower is subject to regulation by a PUC.

The Borrower shall (i) on the existing Stated Maturity Date, prior to or contemporaneous with giving effect to any extension, pay amounts due, in full, to any Declining Lender that is not replaced as a Lender pursuant to Section 10.16, and (ii) prepay any Committed Loans outstanding on the existing Stated Maturity Date which were made to it (and pay any additional amounts required pursuant to Section 3.05) to the extent necessary to keep outstanding Committed Loans ratable with the Pro Rata Shares of all the Lenders.

2.15 Increase in Commitments.

(a) Provided there exists no Default, upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may on a one-time basis request an increase in the Aggregate Commitments to an amount not exceeding $1,000,000,000; provided that any such request for an increase shall be in a minimum amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. At the time of sending such notice, the Borrower (in consultation with the Administrative Agent) shall specify the time period within which each Lender is requested to respond (which shall in no event be less than ten Business Days from the date of delivery of such notice to the Lenders). Each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its Commitment and, if so, whether by an amount equal to, greater than, or less than its Pro Rata Share of such requested increase. Any Lender not responding within such time period shall be deemed to have declined to increase its Commitment. The Administrative Agent shall notify the Borrower and each Lender of the Lenders’ responses to each request made hereunder. To achieve the full amount of a requested increase, the Borrower may also invite additional Eligible Assignees to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel.

(b) If the Aggregate 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. As a condition precedent to such increase, the Borrower shall have provided to the Administrative Agent the following, in form and substance satisfactory to the Administrative Agent (i) copies of corporate resolutions certified by the Secretary or Assistant Secretary of the Borrower, or such other evidence as may be satisfactory to the Administrative Agent, demonstrating that Borrower’s incurrence of indebtedness hereunder in the amount of the Aggregate Commitments as increased pursuant to this Section 2.15 and with a maturity date of the Stated Maturity Date then in effect, has been duly authorized by all necessary corporate action, together with an opinion of counsel to the Borrower (which may be internal counsel) to such effect, (ii) a certificate dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of the Borrower certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article V (including without limitation the representation and warranties set forth in Sections 5.04(c) and 5.05) and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that for purposes of this Section 2.15, the representations and warranties contained in subsections (a) and (b) of Section 5.04 shall be deemed to refer to the most recent statements furnished pursuant to subsections (a) and (b), respectively, of Section 6.01, and (B) no Default exists, (iii) a copy of the securities certificate registered with the Pennsylvania Public Utility Commission and the order of the Pennsylvania Public Utility Commission approving the Borrower’s incurring indebtedness hereunder in the amount of the Aggregate Commitments as increased pursuant to this Section 2.15 and with a maturity date of the Stated Maturity Date then in effect, and (iv) an opinion of counsel to the Borrower (which may be internal counsel) stating that (A) such securities certificate has been registered with the Pennsylvania Public Utility Commission in accordance with Chapter 19 of the Pennsylvania Public Utility Code and by virtue of such registration, authorizes the Borrower to incur indebtedness hereunder in the amount of the Aggregate Commitments as increased pursuant to this Section 2.15 and with a maturity date of the Stated Maturity Date then in effect, and (B) no other Authorizations are required by the Pennsylvania Public Utility Commission or by the PUC in any other state identified by the Borrower as being a state in which the Borrower is subject to regulation by a PUC; provided, however, that the delivery of the items set forth in the foregoing clauses (iii) and (iv) shall not be required as a condition precedent to such increase in the event that the Stated Maturity Date has not been extended pursuant to Section 2.14 prior to the Borrower’s request for such increase.

The Borrower shall prepay any Committed Loans outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 3.05) to the extent necessary to keep the

outstanding Committed Loans ratable with any revised Pro Rata Shares arising from any nonratable increase in the Commitments under this Section.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Any and all payments by the Borrower to or for the account of the Administrative Agent or any Lender under any Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and all liabilities with respect thereto, excluding, in the case of the Administrative Agent and each Lender, taxes imposed on or measured by its overall net income, and franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or any political subdivision thereof) under the Laws of which the Administrative Agent or such Lender, as the case may be, is organized or maintains a lending office (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), each of the Administrative Agent and such Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Laws, and (iv) within 30 days after the date of such payment, the Borrower shall furnish to the Administrative Agent (which shall forward the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof.

(b) In addition, the Borrower agrees to pay any and all present or future stamp, court or documentary taxes and any other excise or property taxes or charges or similar levies which arise from any payment made under any Loan Document or from the execution, delivery, performance, enforcement or registration of, or otherwise with respect to, any Loan Document (hereinafter referred to as “Other Taxes”).

(c) If the Borrower shall be required to deduct or pay any Taxes or Other Taxes from or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, the Borrower shall also pay to the Administrative Agent or to such Lender, as the case may be, at the time interest is paid, such additional amount that the Administrative Agent or such Lender specifies is necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on or measured by net income) that the Administrative Agent or such Lender would have received if such Taxes or Other Taxes had not been imposed.

(d) The Borrower agrees to indemnify the Administrative Agent and each Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section) paid by the Administrative Agent and such Lender, (ii) amounts payable under Section 3.01(c) and (iii) any liability (including additions to tax, penalties, interest and expenses) arising therefrom or with respect thereto, in each case whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. Payment under this subsection (d) shall be made within 30 days after the date the Lender or the Administrative Agent makes a demand therefor.

3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or to determine or charge interest rates based upon the Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to convert Base Rate Committed Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted. Each Lender agrees to designate a different Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender.

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

3.04 Increased Cost and Reduced Return; Capital Adequacy.

(a) If any Lender determines that as a result of the introduction of or any change in or in the interpretation of any Law, or such Lender’s compliance therewith, there shall be any increase in the cost to such Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing (excluding for purposes of this subsection (a) any such increased costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.01 shall govern), (ii) changes in the basis of taxation of overall net income or overall gross income by the United States or any foreign jurisdiction or any political subdivision of either thereof under the Laws of which such Lender is organized or has its Lending Office, and (iii) reserve requirements contemplated by Section 3.04(c)), then from time to time upon demand of such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such increased cost or reduction.

(b) If any Lender determines that the introduction of any Law regarding capital adequacy or any change therein or in the interpretation thereof, or compliance by such Lender (or its Lending Office) therewith, has the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder (taking into consideration its policies with respect to capital adequacy and such Lender’s desired return on capital), then from time to time upon demand of such Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender for such reduction.

(c) The Borrower shall pay to each Lender, as long as such Lender shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits, additional interest on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive), which shall be due and payable on each date on which interest is payable on such Loan, provided the Borrower shall have received at least 15 days’ prior notice (with a copy to the Administrative Agent) of such additional interest from such Lender. If a Lender fails to give notice 15 days prior to the relevant Interest Payment Date, such additional interest shall be due and payable 15 days from receipt of such notice. Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender.

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

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

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

(c) any assignment of a Eurodollar Rate Loan on a day other than the last day of the Interest Period therefor as a result of a request by the Borrower pursuant to Section 10.16;

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

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

3.06 Matters Applicable to all Requests for Compensation. A certificate of the Administrative Agent or any Lender claiming compensation under this Article III and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, the Administrative Agent or such Lender may use any reasonable averaging and attribution methods.

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

ARTICLE IV.

5.02 Corporate and Governmental Authorization; No Contravention. The Borrower’s incurrence of Debt hereunder, and the execution, delivery and performance by the Borrower of this Agreement and the Notes, are within the corporate powers of the Borrower, have been duly authorized by all necessary corporate action, require no action by or in respect of, or filing with, any Governmental Authority (except such as has been obtained), do not contravene, or constitute a default under, any provision of applicable law or regulation or of the certificate of incorporation or by-laws of the Borrower or of any agreement, judgment, injunction, order, decree or other instrument binding upon the Borrower or any of its Subsidiaries, or result in the creation or imposition of any Lien on any asset of the Borrower or any of its Subsidiaries.

5.03 Binding Effect. This Agreement constitutes a valid and binding agreement of the Borrower, and each Note, when executed and delivered in accordance with this Agreement, will constitute a valid and binding obligation of the Borrower, in each case enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency or similar laws of general application relating to the enforcement of creditors’ rights.

5.04 Financial Information.

(a) The consolidated balance sheet of the Borrower and its Consolidated Subsidiaries as of December 31, 2004, and the related consolidated statements of income, cash flows and changes in stockholders’ equity for the fiscal year then ended, reported on by Ernst & Young LLP, independent certified public accountants for the Borrower, and set forth in the Borrower’s 2004 Form 10-K, a copy of which has been delivered to each of the Lenders, (i) fairly present, in conformity with GAAP, the consolidated financial position of the Borrower and its Consolidated Subsidiaries as of such date and their consolidated results of operations and cash flows for such fiscal year, and (ii) show, to the extent required by GAAP, all material indebtedness and other liabilities, direct or contingent, of the Borrower and its Subsidiaries as of the date thereof, including liabilities for taxes, material commitments and Debt.

(b) The unaudited consolidated balance sheet of the Borrower and its Consolidated Subsidiaries as of June 30, 2005, and the related unaudited consolidated statements of income and cash flows for the three months then ended, set forth in the Borrower’s Latest Form 10-Q, a copy of which has been delivered to each of the Lenders, fairly present, in conformity with GAAP applied on a basis consistent with the financial statements referred to in subsection (a) of this Section, the consolidated financial position of the Borrower and its Consolidated Subsidiaries as of such date and their consolidated results of operations and cash flows for such three month period (subject to normal year-end adjustments).

(c) Since December 31, 2004 there has been no material adverse change in the business, financial position or results of operations of the Borrower and its Consolidated Subsidiaries, considered as a whole.

5.05 Litigation. There is no action, suit, proceeding or investigation pending against, or, to the knowledge of the Borrower, threatened against or affecting, the Borrower or any of its Subsidiaries before any Governmental Authority in which there is a reasonable possibility of an adverse decision which could materially adversely affect the business, consolidated financial position or consolidated results of operations of the Borrower and its Consolidated Subsidiaries, considered as a whole, or which in any manner draws into question the validity or enforceability of this Agreement or the Notes.

5.06 No Default. Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any Contractual Obligation which could be reasonably expected to have a material adverse effect on the business, financial condition, results of operations or prospects of the Borrower and its Consolidated Subsidiaries, considered as a whole.

5.07 Compliance with ERISA. Each member of the ERISA Group has fulfilled its obligations under the minimum funding standards of ERISA and the Internal Revenue Code with respect to each Plan and is in compliance in all material respects with the presently applicable provisions of ERISA and the Internal Revenue Code with respect to each Plan. No member of the ERISA Group has (i) sought a waiver of the minimum funding standard under Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to make any contribution or payment to any Plan or Multiemployer Plan or in respect of any Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement, which has resulted or could result in the imposition of a Lien or the posting of a bond or other security under ERISA or the Internal Revenue Code, or (iii) incurred any liability under Title IV of ERISA other than a liability to the PBGC for premiums under Section 4007 of ERISA.

5.08 Environmental Matters. In the ordinary course of its business, the Borrower conducts an ongoing review of the effect of Environmental Laws on the business, operations and properties of the Borrower and its Subsidiaries, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any

license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted thereat, any costs or liabilities in connection with off-site disposal of wastes or Hazardous Substances, and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). On the basis of this review, the Borrower has concluded that such associated liabilities and costs, including the costs of compliance with Environmental Laws, are unlikely to have a material adverse effect on the business, financial condition, results of operations or prospects of the Borrower and its Consolidated Subsidiaries, considered as a whole.

5.09 Taxes. The Borrower and its Subsidiaries have filed all United States Federal income tax returns and all other material tax returns which are required to be filed by them, and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Borrower or any Subsidiary (other than those not yet delinquent and payable without premium or penalty, and except for those being diligently contested in good faith by appropriate proceedings, and in each case, for which adequate reserves and provisions for taxes have been made on the books of the Borrower and each Subsidiary). The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of taxes or other governmental charges are, in the opinion of the Borrower, adequate.

5.10 Subsidiaries. Each of the Borrower’s corporate Subsidiaries is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation, and has all corporate powers and all material governmental authorizations required to carry on its business as now conducted, except where the absence of any of the foregoing could not reasonably be expected to have a material adverse effect on the business, financial condition, results of operations or prospects of the Borrower and its Consolidated Subsidiaries, considered as a whole.

5.11 Regulatory Restrictions on Borrowing; Margin Regulations.

(a) None of the Borrower, any Person Controlling the Borrower, or any Subsidiary is an “investment company” within the meaning of the Investment Company Act of 1940, as amended, or a “holding company,” or a “subsidiary company” of a “holding company,” or an “affiliate” of a “holding company” or of a “subsidiary company” of a “holding company,” within the meaning of the Public Utility Holding Company Act of 1935, as amended.

(b) Margin stock does not constitute more than 25% of the assets of the Borrower and its Subsidiaries.

5.12 Full Disclosure. No statement, information, report, representation, or warranty made by the Borrower in any Loan Document or furnished to the Administrative Agent or any Lender by or on behalf of the Borrower in connection with any Loan Document contains any untrue statement of a material fact or omits any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

Any Loan Document (other than the Fee Letters), at any time after its execution and delivery and for any reason other than as expressly permitted hereunder or satisfaction in full of all the Obligations, ceases to be in full force and effect; or the Borrower or any other Person contests in any manner the validity or enforceability of any Loan Document; or the Borrower denies that it has any or further liability or obligation under any Loan Document, or purports to revoke, terminate or rescind any Loan Document; or

(k) Change of Control. There occurs any Change of Control with respect to the Borrower.

8.02 Remedies Upon Event of Default. If any Event of Default occurs and is continuing, the Administrative Agent shall, at the request of, or may, with the consent of, the Required Lenders, take any or all of the following actions:

(a) declare the commitment of each Lender to make Loans and any obligations of the L/C Issuer to make L/C Credit Extensions to be terminated, whereupon such commitments and obligation shall be terminated;

(b) declare the unpaid principal amount of all outstanding Loans, all interest accrued and unpaid thereon, and all other amounts owing or payable hereunder or under any other Loan Document to be immediately due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by the Borrower;

(c) require that the Borrower Cash Collateralize the L/C Obligations (in an amount equal to the then Outstanding Amount thereof); and

(d) exercise on behalf of itself and the Lenders all rights and remedies available to it and the Lenders under the Loan Documents or applicable law;

provided, however, that upon the occurrence of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States, the obligation of each Lender to make Loans and any obligation of the L/C Issuer to make L/C Credit Extensions shall automatically terminate, the unpaid principal amount of all outstanding Loans and all interest and other amounts as aforesaid shall automatically become due and payable, and the obligation of the Borrower to Cash Collateralize the L/C Obligations as aforesaid shall automatically become effective, in each case without further act of the Administrative Agent or any Lender.

8.03 Application of Funds. After the exercise of remedies provided for in Section 8.02 (or after the Loans have automatically become immediately due and payable and the L/C Obligations have automatically been required to be Cash Collateralized as set forth in the proviso to Section 8.02), any amounts received on account of the Obligations shall be applied by the Administrative Agent in the following order:

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including Attorney Costs and amounts payable under Article III) payable to the Administrative Agent in its capacity as such;

Second, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than principal and interest) payable to the Lenders (including Attorney Costs and amounts payable under Article III), ratably among them in proportion to the amounts described in this clause Second payable to them;

Third, to payment of that portion of the Obligations constituting accrued and unpaid interest on the Loans, ratably among the Lenders in proportion to the respective amounts described in this clause Third payable to them;

Fourth, to payment of that portion of the Obligations constituting unpaid principal of the Loans and L/C Borrowings, ratably among the Lenders in proportion to the respective amounts described in this clause Fourth held by them;

Fifth, to the Administrative Agent for the account of the L/C Issuer, to Cash Collateralize that portion of L/C Obligations comprised of the aggregate undrawn amount of Letters of Credit; and

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required by Law.

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate undrawn amount of Letters of Credit pursuant to clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above.

ARTICLE IX.

ADMINISTRATIVE AGENT

9.01 Appointment and Authorization of Administrative Agent.

Each of the Lenders and the L/C Issuer hereby irrevocably appoints Bank of America to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the

Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the L/C Issuer, and the Borrower shall not have rights as a third party beneficiary of any of such provisions.

9.02 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

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

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

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

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

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

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

9.04 Reliance by Administrative Agent.

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

9.05 Indemnification of Administrative Agent. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not reimbursed by or on behalf of the Borrower and without limiting the obligation of the Borrower to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all Indemnified Liabilities incurred by it; provided, however, that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted from such Agent-Related Person’s own gross negligence or willful misconduct; provided, however, that no action taken in accordance with the directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The obligations of the Lenders in this Section are subject to the provisions of Section 2.12(e) and shall survive termination of the Aggregate Commitments, the payment of all other Obligations and the resignation of the Administrative Agent.

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

9.07 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders, the L/C Issuer and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower (so long as no Event of Default exists), to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the L/C Issuer, appoint a successor Administrative Agent meeting the

qualifications set forth above; provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also constitute its resignation as L/C Issuer and Swing Line Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer and Swing Line Lender, (b) the retiring L/C Issuer and Swing Line Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit.

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

9.09 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the Bookrunners, Arrangers, Documentation Agent or Syndication Agent listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the L/C Issuer hereunder.

9.10 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the L/C Issuer and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuer and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the L/C Issuer and the Administrative Agent under Sections 2.03(i) and (j), 2.09, 10.04 and 10.05) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the L/C Issuer, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.09, 10.04 and 10.05.

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

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (f) or (i) of this Section, or (iv) to an SPC in accordance with the provisions of subsection (h) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time 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 (including for purposes of this subsection (b), participations in L/C Obligations and Swing Line 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 or an Affiliate of a Lender or an Approved Fund (as defined in subsection (g) of this Section) with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000 unless each of the Administrative Agent, each L/C Issuer, and, so long as no Default or Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met; (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned, except that this clause (ii) shall not apply to rights in respect of Swing Line Loans; (iii) any assignment of a Commitment must be approved by the Administrative Agent, the L/C Issuer and the Swing Line Lender unless the Person that is the proposed assignee is itself a Lender (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee), such approval not to be unreasonably withheld or delayed; and (iv) the parties to each assignment shall execute and deliver to the

Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount, if any, required as set forth in Schedule 10.07, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05, 10.04 and 10.05 with respect to facts and circumstances occurring prior to the effective date of such assignment). Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and the L/C Issuer, at any reasonable time and from time to time upon reasonable prior notice. In addition, at any time that a request for a consent for a material or substantive change to the Loan Documents is pending, any Lender may request and receive from the Administrative Agent a copy of the Register.

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including for purposes of this subsection (b), participations in L/C Obligations and/or Swing Line Loans) owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso to Section 10.01 that directly affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.09 as though it were a Lender, provided such Participant agrees to be subject to Section 2.13 as though it were a Lender.

(e) A Participant shall not be entitled to receive any greater payment under Section 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s

prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 10.15 as though it were a Lender.

(f) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

(h) As used herein, the following terms have the following meanings:

“Eligible Assignee” means (a) a Lender; (b) an Affiliate of a Lender; (c) an Approved Fund; and (d) any other Person (other than a natural person) approved by (i) the Administrative Agent, each L/C Issuer, and the Swing Line Lender, and (ii) unless a Default or an Event of Default has occurred and is continuing, the Borrower (each such approval not to be unreasonably withheld or delayed); provided that notwithstanding the foregoing, “Eligible Assignee” shall not include the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

“Fund” means any Person (other than a natural person) that is (or will be) engaged in making, purchasing, holding or otherwise investing in commercial loans and similar extensions of credit in the ordinary course of its business.

“Approved Fund” means any Fund that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(i) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Committed Loan that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Committed Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Committed Loan, the Granting Lender shall be obligated to make such Committed Loan pursuant to the terms hereof. Each party hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall increase the costs or expenses or otherwise increase or change the obligations of the Borrower under this Agreement (including its obligations under Section 3.04), (ii) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, and (iii) the Granting Lender shall for all purposes, including the approval of any amendment, waiver or other modification of any provision of any Loan Document, remain the lender of record hereunder. The making of a Committed Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Committed Loan were made by such Granting Lender. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one

day after the payment in full of all outstanding commercial paper or other senior debt of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained herein, any SPC may (i) with notice to, but without prior consent of the Borrower and the Administrative Agent and with payment of a processing fee of $3,500, assign all or any portion of its right to receive payment with respect to any Committed Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Committed Loans to any rating agency, commercial paper dealer or provider of any surety or Guarantee or credit or liquidity enhancement to such SPC.

(j) Notwithstanding anything to the contrary contained herein, any Lender that is a Fund may create a security interest in all or any portion of the Loans owing to it and the Note, if any, held by it to the trustee for holders of obligations owed, or securities issued, by such Fund as security for such obligations or securities, provided that unless and until such trustee actually becomes a Lender in compliance with the other provisions of this Section 10.07, (i) no such pledge shall release the pledging Lender from any of its obligations under the Loan Documents and (ii) such trustee shall not be entitled to exercise any of the rights of a Lender under the Loan Documents even though such trustee may have acquired ownership rights with respect to the pledged interest through foreclosure or otherwise.

(k) Notwithstanding anything to the contrary contained herein, if at any time Bank of America assigns all of its Commitment and Loans pursuant to subsection (b) above, Bank of America may, (i) upon 30 days’ notice to the Borrower and the Lenders, resign as L/C Issuer and/or (ii) upon 30 days’ notice to the Company, resign as Swing Line Lender. In the event of any such resignation as L/C Issuer or Swing Line Lender, the Borrower shall be entitled to appoint from among the Lenders a successor L/C Issuer or Swing Line Lender hereunder; provided, however, that no failure by the Borrower to appoint any such successor shall affect the resignation of Bank of America as L/C Issuer or Swing Line Lender, as the case may be. If Bank of America resigns as L/C Issuer, it shall retain all the rights and obligations of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto (including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c)). If Bank of America resigns as Swing Line Lender, it shall retain all the rights of the Swing Line Lender provided for hereunder with respect to Swing Line Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Committed Loans or fund risk participations in outstanding Swing Line Loans pursuant to Section 2.04(c). Upon the appointment of a successor L/C Issuer and/or Swing Line Lender, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer or Swing Line Lender, as the case may be, and (b) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such Letters of Credit.

10.08 Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent requested by any regulatory authority; (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to any other party to this Agreement; (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any direct or indirect contractual counterparty or prospective counterparty (or such contractual

counterparty’s or prospective counterparty’s professional advisor) to any credit derivative transaction relating to obligations of the Borrower; (g) with the consent of the Borrower; (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower; or (i) to the National Association of Insurance Commissioners or any other similar organization. In addition, the Administrative Agent and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry, and service providers to the Administrative Agent and the Lenders in connection with the administration and management of this Agreement, the other Loan Documents, the Commitments, and the Credit Extensions. For purposes of this Section, “Information” means all information received from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the L/C Issuer on a nonconfidential basis prior to disclosure by the Borrower or any Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

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

10.09 Set-off. In addition to any rights and remedies of the Lenders provided by law, upon the occurrence and during the continuance of any Event of Default, each Lender is authorized at any time and from time to time, without prior notice to the Borrower, any such notice being waived by the Borrower to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender to or for the credit or the account of the Borrower against any and all Obligations owing to such Lender hereunder or under any other Loan Document, now or hereafter existing, irrespective of whether or not the Administrative Agent or such Lender shall have made demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or indebtedness. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set-off and application made by such Lender; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

10.10 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

To the extent that the interest rate laws of the State of Texas are applicable to the Loans for purposes of determining the “maximum rate” or the “maximum amount,” then those terms mean the “weekly ceiling” from time to time in effect under Texas Finance Code § 303.001, as limited by Texas

Finance Code § 303.009, and, to the extent that this Agreement is deemed an open end account as such term is defined in Texas Finance Code Section 301.002(a)(14), the Lenders retain the right to modify the interest rate in accordance with applicable law.

The parties agree that Texas Finance Code, Chapter 346, which regulates certain revolving loan accounts and revolving triparty accounts, shall not apply to any revolving loan accounts created under this Agreement or the Notes or maintained in connection therewith.

10.11 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10.12 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

10.13 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

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

10.15 Tax Forms. (a) (i) Each Lender that is not a “United States person” within the meaning of Section 7701(a)(30) of the Code (a “Foreign Lender”) shall deliver to the Administrative Agent, prior to receipt of any payment subject to withholding under the Code (or upon accepting an assignment of an interest herein), two duly signed completed copies of either IRS Form W-8BEN or any successor thereto (relating to such Foreign Lender and entitling it to an exemption from, or reduction of, withholding tax on all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement) or such other evidence satisfactory to the Borrower and the Administrative Agent that such Foreign Lender is entitled to an exemption from, or reduction of, U.S. withholding tax, including any exemption pursuant to Section 881(c) of the Code. Thereafter and from time to time, each such Foreign Lender shall (A) promptly submit to the Administrative Agent such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to the Borrower and the Administrative Agent of any available exemption from or reduction of, United States

withholding taxes in respect of all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement, (B) promptly notify the Administrative Agent of any change in circumstances which would modify or render invalid any claimed exemption or reduction, and (C) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re-designation of its Lending Office) to avoid any requirement of applicable Laws that the Borrower make any deduction or withholding for taxes from amounts payable to such Foreign Lender.

(ii) Each Foreign Lender, to the extent it does not act or ceases to act for its own account with respect to any portion of any sums paid or payable to such Lender under any of the Loan Documents (for example, in the case of a typical participation by such Lender), shall deliver to the Administrative Agent on the date when such Foreign Lender ceases to act for its own account with respect to any portion of any such sums paid or payable, and at such other times as may be necessary in the determination of the Administrative Agent (in the reasonable exercise of its discretion), (A) two duly signed completed copies of the forms or statements required to be provided by such Lender as set forth above, to establish the portion of any such sums paid or payable with respect to which such Lender acts for its own account that is not subject to U.S. withholding tax, and (B) two duly signed completed copies of IRS Form W-8IMY (or any successor thereto), together with any information such Lender chooses to transmit with such form, and any other certificate or statement of exemption required under the Code, to establish that such Lender is not acting for its own account with respect to a portion of any such sums payable to such Lender.

(iii) The Borrower shall not be required to pay any additional amount to any Foreign Lender under Section 3.01 (A) with respect to any Taxes required to be deducted or withheld on the basis of the information, certificates or statements of exemption such Lender transmits with an IRS Form W-8IMY pursuant to this Section 10.15(a) or (B) if such Lender shall have failed to satisfy the foregoing provisions of this Section 10.15(a); provided that if such Lender shall have satisfied the requirement of this Section 10.15(a) on the date such Lender became a Lender or ceased to act for its own account with respect to any payment under any of the Loan Documents, nothing in this Section 10.15(a) shall relieve the Borrower of its obligation to pay any amounts pursuant to Section 3.01 in the event that, as a result of any change in any applicable law, treaty or governmental rule, regulation or order, or any change in the interpretation, administration or application thereof, such Lender is no longer properly entitled to deliver forms, certificates or other evidence at a subsequent date establishing the fact that such Lender or other Person for the account of which such Lender receives any sums payable under any of the Loan Documents is not subject to withholding or is subject to withholding at a reduced rate.

(iv) The Administrative Agent may, without reduction, withhold any Taxes required to be deducted and withheld from any payment under any of the Loan Documents with respect to which the Borrower is not required to pay additional amounts under this Section 10.15(a).

(b) Upon the request of the Administrative Agent, each Lender that is a “United States person” within the meaning of Section 7701(a)(30) of the Code shall deliver to the Administrative Agent two duly signed completed copies of IRS Form W-9. If such Lender fails to deliver such forms, then the Administrative Agent may withhold from any interest payment to such Lender an amount equivalent to the applicable back-up withholding tax imposed by the Code, without reduction.

(c) If any Governmental Authority asserts that the Administrative Agent did not properly withhold or backup withhold, as the case may be, any tax or other amount from payments made to or for the account of any Lender, such Lender shall indemnify the Administrative Agent therefore, including all penalties and interest, any taxes imposed by any jurisdiction on the amounts payable to the Administrative Agent under this Section, and costs and expenses (including Attorney Costs) of the Administrative Agent. The obligation of the Lenders under this Section shall survive the termination of the Aggregate Commitments, repayment of all other Obligations hereunder and the resignation of the Administrative Agent.

10.16 Replacement of Lenders.

If any Lender requests compensation under Section 3.04, if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, if any Lender is a Defaulting Lender, or if any other circumstance exists hereunder that gives the Borrower the right to replace a Lender as a party hereto, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.07), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(a) the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 10.07(b);

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

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

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

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

10.17 Governing Law.

(a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

(b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN XXX XXXXXX XX XXX XXXXX XX XXX XXXX SITTING IN THE BOROUGH OF MANHATTAN OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER

10.19 USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of each Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Borrower in accordance with the Act.

10.20 Termination of Commitments Under Existing Credit Agreement. The commitments of the Existing Lenders under the Existing Credit Agreement shall terminate on the Closing Date. Execution of this Agreement by Lenders who are Existing Lenders shall constitute a waiver of the notice provisions in Sections 2.09 and 9.01 of the Existing Credit Agreement.

10.21 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.
