Subject to Section 2.2(b) hereof, the obligation of the Borrower to reimburse the applicable Issuing Agent for all drawings under a Letter of Credit (a “Reimbursement Obligation”) shall be governed, to the extent not inconsistent with this Agreement, by the Supplemental Letter of Credit Agreement related to such Letter of Credit, except that (i) reimbursement of each drawing paid prior to 1:30 p.m. (New York time) shall be made in immediately available funds at the applicable office of Issuing Agent which has been designated by it to the Borrower in writing for such purpose on the date when such drawing is paid or (ii) if such drawing was paid after 1:30 p.m. (New York time), by 12:00 noon (New York time) on the next Business Day. If the Borrower does not make any such reimbursement payment on the date due (whether through a deemed request for a Base Rate Loan pursuant to Section 2.5(c) hereof or otherwise) and the Banks fund their participations therein in the manner set forth in Section 2.2(d) hereof, then all payments thereafter received by an Issuing Agent in discharge of any of the relevant Reimbursement Obligations shall be distributed in accordance with Section 2.2(d) hereof. An Issuing Agent shall notify the Borrower and the Administrative Agent promptly of its intent to pay, or payment of, a drawing under a Letter of Credit.

(d) The Participating Interests. Each Bank, by its acceptance hereof, severally agrees to purchase from each Issuing Agent, and each Issuing Agent hereby agrees to sell to each such Bank, an undivided percentage participating interest (a “Participating Interest”), to the extent of its Percentage, in each Letter of Credit issued by, and each Reimbursement Obligation owed to, such Issuing Agent. Upon any failure by the Borrower to pay any Reimbursement Obligation by the time required as set forth in Section 2.2(c) hereof, or if an Issuing Agent is required at any time to return to the Borrower or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment of any Reimbursement Obligation, each Bank shall, not later than the Business Day it receives a demand from the Administrative Agent on behalf of such Issuing Agent (which Issuing Agent hereby covenants and agrees it will deliver to the Administrative Agent) to such effect, if such demand is received before 2:00 p.m. (New York time), or not later than the following Business Day, if such demand is received after such time, pay to such Issuing Agent an amount equal to its Percentage of such unpaid or recaptured Reimbursement Obligation together with interest on such amount accrued from the date the related payment was made

by such Issuing Agent to the date of such payment by such Bank a rate per annum equal to (i) from the date the related payment was made by such Issuing Agent to the date two (2) Business Days after payment by such Bank is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Bank to the date such payment is made by such Bank, the Base Rate in effect for each such day. Each such Bank shall thereafter be entitled to receive its Percentage of each payment received in respect of the relevant Reimbursement Obligation and of interest paid thereon, with the applicable Issuing Agent retaining its Percentage as a Bank hereunder.

The several obligations of the Banks to the Issuing Agents under this Section 2.2(d) shall be absolute, irrevocable and unconditional under any and all circumstances whatsoever and shall not be subject to any set-off, counterclaim or defense to payment which any Bank may have or have had against the Borrower, the Administrative Agent, the Issuing Agents, any Bank or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any reduction or termination of any Commitment of any Bank, and each payment by a Bank under this Section 2.2 shall be made without any offset, abatement, withholding or reduction whatsoever. The Issuing Agents and the Administrative Agent shall be entitled to offset amounts received for the account of a Bank under the Credit Documents against unpaid amounts due from such Bank to the applicable Issuing Agent or the Administrative Agent, as applicable, hereunder (whether as fundings of participations, indemnities or otherwise).

(e) Indemnification. The Banks shall, to the extent of their respective Percentages, indemnify each Issuing Agent (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except to the extent resulting from such Issuing Agent’s gross negligence or willful misconduct as determined in a final, non-appealable judgment by a court of competent jurisdiction) that an Issuing Agent may suffer or incur in connection with any Letter of Credit issued by it. The Issuing Agents shall be entitled to all of the rights and protections afforded the Administrative Agent under Section 10 hereof. The obligations of the Banks under this Section 2.2(e) and all other parts of this Section 2.2 shall survive termination of this Agreement and of all other L/C Documents.

(f) Issuing Agents. Each Bank hereby appoints U.S. Bank National Association, and any other Person who satisfies the definition of Issuing Agent, as the Issuing Agents hereunder and hereby authorizes each of the Issuing Agents to take such action as Issuing Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Issuing Agents by the terms thereof, together with such powers as are reasonably incidental thereto. The relationship between each of the Issuing Agents and the Banks is and shall be that of agent and principal only, and nothing contained in this Agreement or any other Credit Document shall be construed to constitute a Issuing Agent as a trustee or fiduciary for any Bank or the Borrower.

Section 2.3 Applicable Interest Rates. (a) Base Rate Loans. Each Base Rate Loan made or maintained by a Bank shall bear interest during each Interest Period it is outstanding (computed

(x) at all times the Base Rate is based on the rate described in clause (i) of the definition thereof, on the basis of a year of 365 or 366 days, as applicable, and actual days elapsed or (y) at all times the Base Rate is based on the rate described in clause (ii) or (iii) of the definition thereof, on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, continued or created by conversion from a Eurodollar Loan until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect, payable on the last day of its Interest Period and at maturity (whether by acceleration or otherwise) and no less frequently than quarterly.

“Base Rate” means for any day the greatest of:

(i) the rate of interest announced by U.S. Bank National Association from time to time as its prime rate, or equivalent, for U.S. Dollar loans within the United States as in effect on such day, with any change in the Base Rate resulting from a change in said prime rate to be effective as of the date of the relevant change in said prime rate;

(ii) the sum of (x) the Federal Funds Rate, plus (y) one half of one percent (0.50%); and

(iii) the rate per annum appearing on a nationally recognized service such as Reuters Screen LIBOR01 Page (or on any successor or substitute page of such page) as the rate for deposits in U.S. Dollars for a one month interest period commencing on the date of determination, plus 1.00%.

(b) Eurodollar Loans. Each Eurodollar Loan made or maintained by a Bank shall bear interest during each Interest Period it is outstanding (computed on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, continued, or created by conversion from a Base Rate Loan until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Adjusted LIBOR applicable for such Interest Period, payable on the last day of the Interest Period and at maturity (whether by acceleration or otherwise), and, if the applicable Interest Period is longer than three months, on each day occurring every three months after the commencement of such Interest Period.

“Adjusted LIBOR” means, for any Borrowing of Eurodollar Loans, a rate per annum determined in accordance with the following formula:


Adjusted LIBOR =	LIBOR _

1 - Eurodollar Reserve Percentage

“LIBOR” means, for an Interest Period for a Borrowing of Eurodollar Loans, (a) the LIBOR Index Rate for such Interest Period, if such rate is available, (b) if the LIBOR Index Rate cannot be determined, the arithmetical average of the rates of interest per annum at which deposits in U.S.

Dollars, in immediately available funds are offered to the Administrative Agent at 11:00 a.m. (London, England time) two (2) Business Days before the beginning of such Interest Period by major banks in the interbank eurodollar market for delivery on the first day of and for a period equal to such Interest Period in an amount equal or comparable to the principal amount of the Eurodollar Loan scheduled to be made by U.S. Bank as part of such Borrowing, and (c) solely with respect to the Initial Designated Borrowings, for the Interest Period in respect thereof, 0.625%.

On the Business Day following the end of the Interest Period with respect to the Initial Designated Borrowing, the Borrower shall pay to the Administrative Agent for the account of each Bank additional interest on the Initial Designated Borrowing for the Interest Period with respect thereto at a rate per annum equal to the amount by which the three (3) month rate per annum for deposits in U.S. Dollars for delivery on the first day of such period as quoted on the applicable Reuters screen at 11:00 a.m. (London, England time) on the day two (2) Business Days before the Effective Date exceeds 0.625%.

“LIBOR Index Rate” means, for any Interest Period, the rate per annum for deposits in U.S. Dollars for delivery on the first day of and for a period equal to such Interest Period in an amount equal or comparable to the principal amount of the Eurodollar Loan scheduled to be made by U.S. Bank as part of such Borrowing, which appears on a nationally recognized service such as Reuters Screen LIBOR01 Page (or any successor or substitute page of such page) as the rate for deposit in U.S. Dollars for such Interest Period on the day two (2) Business Days before the commencement of such Interest Period.

“Eurodollar Reserve Percentage” means for a Borrowing of Eurodollar Loans from any Bank, the daily average for the applicable Interest Period of the actual effective rate, expressed as a decimal, at which reserves (including, without limitation, any supplemental, marginal and emergency reserves) are maintained by such Bank during such Interest Period pursuant to Regulation D of the Board of Governors of the Federal Reserve System (or any successor) on “eurocurrency liabilities,” as defined in such Board’s Regulation D (or in respect of any other category of liabilities that includes deposits by reference to which the interest rate on Eurodollar Loans is determined or any category of extensions of credit or other assets that include loans by non-United States offices of any Bank to United States residents), subject to any amendments of such reserve requirement by such Board or its successor, taking into account any transitional adjustments thereto. For purposes of this definition, the Eurodollar Loans shall be deemed to be “eurocurrency liabilities” as defined in Regulation D without benefit or credit for any prorations, exemptions or offsets under Regulation D.

(c) Daily Eurodollar Rates. Notwithstanding the foregoing, each Swing Line Loan shall bear interest on the outstanding principal amount thereof, for each day from and including the day such Swing Line Loan is made to but excluding the date it is paid, at a rate per annum equal to, at the Borrower’s option, the Daily Eurodollar Rate or the Base Rate plus an applicable margin agreed to by the Borrower and the Swing Line Bank.

“Daily Eurodollar Base Rate” means, with respect to a Swing Line Loan, the LIBOR Index

Rate for one month appearing on the applicable Reuters Screen LIBOR01 as of 11:00 a.m. (London, England time) on a Business Day, provided that, if the LIBOR Index Rate cannot be determined, the applicable Daily Eurodollar Base Rate for one month shall instead be the arithmetical average of the rates of interest per annum at which deposits in U.S. Dollars in immediately available funds are offered to the Administrative Agent at 11:00 a.m. (London, England time) on a Business Day by major banks in the interbank eurodollar market in an amount equal or comparable to the principal amount of the relevant Swing Line Loan and having a maturity equal to one month. For purposes of determining any interest rate hereunder or under any other Credit Document which is based on the Daily Eurodollar Base Rate, such interest rate shall change as and when the Daily Eurodollar Base Rate shall change.

“Daily Eurodollar Loan” means a Swing Line Loan which, except as otherwise provided in this Section 2.3(c), bears interest at the Daily Eurodollar Rate.

“Daily Eurodollar Rate” means, with respect to a Swing Line Loan, the sum of (a) the quotient of (i) the Daily Eurodollar Base Rate, divided by (ii) one minus the Eurodollar Reserve Percentage (expressed as a decimal) applicable to such Interest Period, plus (b) the Applicable Margin.

(d) Rate Determinations. The Administrative Agent shall determine each interest rate applicable to Obligations, and a determination thereof by the Administrative Agent shall be conclusive and binding except in the case of manifest error.

Section 2.4 Minimum Borrowing Amounts. Each Borrowing of Base Rate Loans (other than a Borrowing to repay Swing Line Loans) and Eurodollar Loans shall be in an amount not less than $2,000,000 and integral multiples of $1,000,000 in excess thereof; provided, a Borrowing of Base Rate Loans applied to pay a Reimbursement Obligation pursuant to Section 2.5(c) hereof shall be in an amount equal to such Reimbursement Obligation.

Section 2.5 Manner of Borrowing Loans and Designating Interest Rates Applicable to Loans.

(a) Notice to the Administrative Agent. The Borrower shall give notice to the Administrative Agent in the form of Exhibit E-1 (a “Borrowing Notice”) by no later than 1:00 p.m. (New York time) (i) at least three (3) Business Days before the date on which the Borrower requests the Banks to advance a Borrowing of Eurodollar Loans, or (ii) on the date on which the Borrower requests the Banks to advance a Borrowing of Base Rate Loans. The Loans included in each Borrowing shall bear interest initially at the type of rate specified in such notice of a new Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Borrowing or, subject to the minimum amount requirement for each outstanding Borrowing set forth in Section 2.4 hereof, a portion thereof, as follows: (i) if such Borrowing is of Eurodollar Loans, on the last day of the Interest Period applicable thereto, the Borrower may continue part or all of such Borrowing as Eurodollar Loans for an Interest Period or Interest Periods specified by

the Borrower or convert part or all of such Borrowing into Base Rate Loans, and (ii) if such Borrowing is of Base Rate Loans, on any Business Day, the Borrower may convert all or part of such Borrowing into Eurodollar Loans for an Interest Period or Interest Periods specified by the Borrower. The Borrower shall give all such notices requesting the advance, continuation, or conversion of a Borrowing to the Administrative Agent by telephone, telecopy or email of a properly executed pdf (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing). Notices of the continuation of a Borrowing of Eurodollar Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Eurodollar Loans into Base Rate Loans or of Base Rate Loans into Eurodollar Loans shall be in the form of Exhibit E-2 (a “Conversion/Continuation Notice”) and must be given by no later than 1:00 p.m. (New York time) at least three (3) Business Days before the date of the requested continuation or conversion. All such notices concerning the advance, continuation, or conversion of a Borrowing shall be irrevocable once given and shall specify the date of the requested advance, continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be advanced, continued, or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. The Borrower agrees that the Administrative Agent may rely on any such telephonic or telecopy notice given by any person it in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts with any written confirmation, such telephonic notice shall govern if the Administrative Agent has acted in reliance thereon. There may be no more than eight (8) different Interest Periods in effect at any one time, provided that for purposes of determining the number of Interest Periods in effect at any one time, all Base Rate Loans and all Swing Line Loans shall be deemed to have one and the same Interest Period.

(b) Notice to the Banks. The Administrative Agent shall give prompt telephonic or telecopy notice to each Bank of any Borrowing Notice or Conversion/Continuation Notice from the Borrower received pursuant to Section 2.5(a) hereof or Swing Line Borrowing Notice from the Borrower received pursuant to Section 2.2(b) hereof. The Administrative Agent shall give notice to the Borrower and each Bank by like means of the interest rate applicable to each Borrowing of Eurodollar Loans.

(c) Borrower’s Failure to Notify. Any outstanding Borrowing of Base Rate Loans shall, subject to Section 6.2 hereof, automatically be continued for an additional Interest Period on the last day of its then current Interest Period unless the Borrower has notified the Administrative Agent within the period required by Section 2.5(a) hereof that it intends to convert such Borrowing into a Borrowing of Eurodollar Loans or notifies the Administrative Agent within the period required by Section 2.8(a) hereof that it intends to prepay or repay such Borrowing. If the Borrower fails to give notice pursuant to Section 2.5(a) hereof of the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans before the last day of its then current Interest Period within the period required by Section 2.5(a) hereof and has not notified the Administrative Agent within the period required by Section 2.8(a) hereof that it intends to prepay such Borrowing,

such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans, subject to Section 6.2 hereof. The Administrative Agent shall promptly notify the Banks of the Borrower’s failure to so give a notice under Section 2.5(a) hereof. In the event the Borrower fails to give notice pursuant to Section 2.5(a) hereof of a Borrowing equal to the amount of a Reimbursement Obligation and has not notified the Administrative Agent by 12:00 noon (New York time) on the day such Reimbursement Obligation becomes due that it intends to repay such Reimbursement Obligation through funds not borrowed under this Agreement, the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans on such day in the amount of the Reimbursement Obligation then due, subject to Section 6.2 hereof, which Borrowing shall be applied to pay the Reimbursement Obligation then due.

(d) Disbursement of Loans. Not later than 12:00 noon (New York time) on the date of any requested advance of a new Borrowing of Eurodollar Loans, and not later than 2:00 p.m. (New York time) on the date of any requested advance of a new Borrowing of Base Rate Loans, subject to Section 6 hereof, each Bank shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent. The Administrative Agent shall make available to the Borrower Loans in the type of funds received by the Administrative Agent from the Banks.

(e) Administrative Agent Reliance on Bank Funding. Unless the Administrative Agent shall have been notified by a Bank (i) with respect to Eurodollar Loans, before the date on which such Bank is scheduled to make payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) or (ii) with respect to Base Rate Loans, no later than 2:00 p.m. (New York time) on the due date thereof, that such Bank does not intend to make such payment, the Administrative Agent may assume that such Bank has made such payment when due and the Administrative Agent may in reliance upon such assumption (but shall not be required to) make available to the Borrower the proceeds of the Loan to be made by such Bank and, if any Bank has not in fact made such payment to the Administrative Agent, such Bank shall, on demand, pay to the Administrative Agent the amount made available to the Borrower attributable to such Bank together with interest thereon in respect of each day during the period commencing on the date such amount was made available to the Borrower and ending on (but excluding) the date such Bank pays such amount to the Administrative Agent at a rate per annum equal to (i) from the date the related payment was made by the Administrative Agent to the date two (2) Business Days after payment by such Bank is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Bank to the date such payment is made by such Bank, the Base Rate in effect for each such day. If such amount is not received from such Bank by the Administrative Agent immediately upon demand, the Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan attributable to such Bank with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan.

Section 2.6 Interest Periods. As provided in Section 2.5(a) hereof, at the time of each

request for a Borrowing of Eurodollar Loans, the Borrower shall select an Interest Period applicable to such Loans from among the available options. The term “Interest Period” means the period commencing on the date a Borrowing of Loans is advanced, continued, or created by conversion and ending: (a) in the case of Base Rate Loans or Swing Line Loans, on the last Business Day of the calendar quarter in which such Borrowing is advanced, continued, or created by conversion (or on the last day of the following calendar quarter if such Loan is advanced, continued or created by conversion on the last Business Day of a calendar quarter) and (b) in the case of Eurodollar Loans, 1, 2, 3 or 6 months (or, solely in the case of the initial Interest Period in respect of the Initial Designated Borrowings, 75 days) thereafter; provided, however, that:

(a) any Interest Period for a Borrowing of Base Rate Loans or Swing Line Loans that otherwise would end after the Termination Date shall end on the Termination Date;

(b) for any Borrowing of Eurodollar Loans, the Borrower may not select an Interest Period that extends beyond the Termination Date;

(c) whenever the last day of any Interest Period would otherwise be a day that is not a Business Day, the last day of such Interest Period shall be extended to the next succeeding Business Day, provided that, if such extension would cause the last day of an Interest Period for a Borrowing of Eurodollar Loans to occur in the following calendar month, the last day of such Interest Period shall be the immediately preceding Business Day; and

(d) for purposes of determining an Interest Period for a Borrowing of Eurodollar Loans, a month means a period starting on one day in a calendar month and ending on the numerically corresponding day in the next calendar month; provided, however, that if there is no numerically corresponding day in the month in which such an Interest Period is to end or if such an Interest Period begins on the last Business Day of a calendar month, then such Interest Period shall end on the last Business Day of the calendar month in which such Interest Period is to end; provided, further, that solely with respect to the Initial Designated Borrowings, the initial Interest Period shall end on and include the day which is 75 days after the Effective Date.

Section 2.7 Maturity of Loans. Unless an earlier maturity is provided for hereunder (whether by acceleration or otherwise), all Obligations (including principal and interest on all outstanding Loans) shall mature and become due and payable by the Borrower on the Termination Date.

Section 2.8 Prepayments.

(a) The Borrower may prepay any Borrowing of Eurodollar Loans or Base Rate Loans without premium or penalty and in whole or in part (but, if in part, then (i) in an amount not less than $2,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) in an amount such that the minimum amount required for a Borrowing pursuant to Section

2.4 hereof remains outstanding) upon irrevocable notice to the Administrative Agent in the form of Exhibit E-3 (a “Paydown Notice”) (i) in the case of a Borrowing of Eurodollar Loans, three (3) Business Days prior to such prepayment, or (ii) in the case of a Borrowing of Base Rate Loans (other than Swing Line Loans), no later than 2:00 p.m. (New York time) on the date of prepayment, such prepayment to be made by the payment of the principal amount to be prepaid and accrued interest thereon to the date fixed for prepayment. The Borrower may at any time pay, without penalty or premium, all outstanding Swing Line Loans, or any portion of the outstanding Swing Line Loans, upon delivery of a Paydown Notice to the Administrative Agent and the Swing Line Bank by 2:00 p.m. (New York time) on the date of repayment. In the case of Eurodollar Loans, any amounts owing under Section 2.11 hereof as a result of such prepayment shall be paid contemporaneously with such prepayment. The Administrative Agent will promptly advise each Bank of any such prepayment notice it receives from the Borrower. Any amount paid or prepaid before the Termination Date may, subject to the terms and conditions of this Agreement, be borrowed, repaid and borrowed again.

(b) If the aggregate amount of outstanding Loans and L/C Obligations shall at any time for any reason exceed the Commitments then in effect or the amount of L/C Obligations at any time outstanding attributable to Marketing Subsidiary Letters of Credit exceeds the Marketing Subsidiary Sublimit, the Borrower shall, immediately and without notice or demand, pay the amount of such excess to the Administrative Agent for the ratable benefit of the Banks as a prepayment of the Loans and, if necessary, a prefunding of Letters of Credit. Immediately upon determining the need to make any such prepayment the Borrower shall notify the Administrative Agent of such required prepayment. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and shall be subject to Section 2.11 hereof.

Section 2.9 Default Rate. If any payment of principal or interest on any Loan, or payment of any other Obligation, is not made when due (whether by acceleration or otherwise), such principal, interest or other Obligation shall bear interest (computed on the basis of a year of 360 days and actual days elapsed or, if based on the rate described in clause (i) of the definition of Base Rate, on the basis of a year of 365 or 366 days, as applicable, and the actual number of days elapsed) from the date such payment was due until paid in full, payable on demand, at a rate per annum equal to:

(a) for any Obligation other than a Eurodollar Loan (including principal and interest relating to Base Rate Loans and interest on Eurodollar Loans), the sum of two percent (2.00%) plus the Applicable Margin plus the Base Rate from time to time in effect; and

(b) for the principal of any Eurodollar Loan, the sum of two percent (2.00%) plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of two percent (2.00%) plus the Applicable Margin plus the Base Rate from time to time in effect.

Section 2.10 The Notes.

(a) The Loans made to the Borrower by each Bank shall, upon the written request of any such Bank, be evidenced by a single promissory note, or in the case of the Swing Line Bank, a promissory note reflecting the Revolving Loans and a promissory note reflecting the Swing Line Loans, of the Borrower issued to such Bank in the form of Exhibit A hereto, with appropriate changes for notes evidencing Swing Line Loans. Each such promissory note is hereinafter referred to as a “Note” and collectively such promissory notes are referred to as the “Notes.”

(b) Each Bank shall record on its books and records or on a schedule to its Note (if any) the amount of each Loan advanced, continued, or converted by it, all payments of principal and interest and the principal balance from time to time outstanding thereon, the type of such Loan, and, for any Eurodollar Loan, the Interest Period and the interest rate applicable thereto. The record thereof, whether shown on such books and records of a Bank or on a schedule to any Note, shall be prima facie evidence of the same; provided, however, that the failure of any Bank to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of the Borrower to repay all Loans made hereunder together with accrued interest thereon. At the written request of any Bank and upon such Bank tendering to the Borrower the Note to be replaced, the Borrower shall furnish a new Note to such Bank to replace any outstanding Note, and at such time the first notation appearing on a schedule on the reverse side of, or attached to, such Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

Section 2.11 Funding Indemnity. If any Bank shall incur any loss, cost or expense (including, without limitation, any loss, cost or expense (excluding loss of margin) incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Bank to fund or maintain any Eurodollar Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to such Bank) as a result of:

(a) any payment (whether by acceleration or otherwise), prepayment or conversion of a Eurodollar Loan on a date other than the last day of its Interest Period,

(b) any failure (because of a failure to meet the conditions of Section 6 hereof or otherwise) by the Borrower to borrow or continue a Eurodollar Loan, or to convert a Base Rate Loan into a Eurodollar Loan, on the date specified in a notice given pursuant to Section 2.5(a) hereof or established pursuant to Section 2.5(c) hereof,

(c) any failure by the Borrower to make any payment or prepayment of principal on any Eurodollar Loan when due (whether by acceleration or otherwise), or

(d) any acceleration of the maturity of a Eurodollar Loan as a result of the occurrence of any Event of Default hereunder,

then, upon the demand of such Bank, the Borrower shall pay to such Bank such amount as will reimburse such Bank for such loss, cost or expense. If any Bank makes such a claim

for compensation, it shall provide to the Borrower, with a copy to the Administrative Agent, a certificate executed by an officer of such Bank setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such certificate if reasonably calculated shall be prima facie evidence of the amount of such loss, cost or expense.

Section 2.12 Commitments.

(a) The Borrower shall have the right at any time and from time to time, upon three (3) Business Days’ prior written notice to the Administrative Agent, to terminate an unused portion of the Commitments without premium or penalty, in whole or in part, any partial termination to be (i) in an amount not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) allocated ratably among the Banks in proportion to their respective Percentages, provided that the Commitments may not be reduced to an amount less than the sum of the Loans and all L/C Obligations then outstanding. The Administrative Agent shall give prompt notice to each Bank of any such termination of Commitments. Any termination of Commitments pursuant to this Section 2.12 may not be reinstated.

(b) So long as Sections 6.2(b) and (c) hereof are satisfied, the Borrower, with the prior written consent of the Administrative Agent and the Issuing Agents (which, in each case, shall not be unreasonably conditioned or withheld), may from time to time add additional financial institutions as parties to this Agreement or, with the prior written consent of the Administrative Agent, the Issuing Agents (which, in each case, shall not be unreasonably conditioned or withheld) and an existing Bank, increase the Commitment of such existing Bank (any such financial institution or existing Bank which is increasing its commitment being referred to as an “Added Bank”) pursuant to documentation reasonably satisfactory to the Borrower and the Administrative Agent and provided that the minimum commitment of each such Added Bank equals or exceeds $10,000,000, any such Added Bank shall for all purposes be considered a Bank for purposes of this Agreement and the other Credit Documents with a Commitment as set forth in such documentation. No Bank shall be obligated in any way whatsoever to increase its Commitment or provide a new Commitment. Any such Added Bank shall on the date it is deemed a party to this Agreement purchase from the other Banks its Percentage (or the increase in its Percentage, in the case of an Added Bank which is an existing Bank) of the Loans outstanding and shall be deemed to purchase pursuant to Section 2.2(d) hereof a Participating Interest in all Letters of Credit and Reimbursement Obligations outstanding on such date to the extent of its Percentage (or the increase in its Percentage, in the case of an Added Bank which is an existing Bank). Notwithstanding anything contained in this Section 2.12(b) to the contrary, any increase shall be in minimum increments of $5,000,000 and the aggregate amount of Commitments may not, without the consent of the Required Banks, at any time exceed an amount equal to (x) $750,000,000 less (y) the aggregate amount of any Commitment reductions pursuant to Section 2.12(a) hereof.

Section 2.13 [Reserved].Defaulting Banks

(a) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Bank pursuant to Section 3.1 hereof;

(b) if any Swing Line Loans shall be outstanding or any L/C Obligations shall exist at the time a Bank becomes a Defaulting Bank then:

(i) all or any part of the unfunded participations in and commitments with respect to such Swing Line Loans and L/C Obligations of such Defaulting Bank shall be reallocated among the Non-Defaulting Banks in accordance with their respective Percentages but only to the extent that no Default or Event of Default has occurred and is continuing, and that as a result thereof (x) the sum of all Non-Defaulting Banks’ outstanding Loans plus such Defaulting Bank’s L/C Obligations and Swing Line Loans would not exceed the Non-Defaulting Banks’ existing Commitments and (y) the sum of each Non-Defaulting Bank’s outstanding Loans plus such Non-Defaulting Bank’s share under this clause (i) of such Defaulting Bank’s L/C Obligations and Swing Line Loans would not exceed such Non-Defaulting Bank’s existing Commitment; and

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one (1) Business Day following notice by the Administrative Agent (x) first, prepay the outstanding Swing Line Loans that were not reallocated and (y) second, cash collateralize such Defaulting Bank’s L/C Obligations (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth herein for so long as such L/C Obligations are outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Bank’s L/C Obligations pursuant to this Section 2.14(b), the Borrower shall not be required to pay any fees to such Defaulting Bank pursuant to Section 3.1 hereof with respect to such Defaulting Bank’s L/C Obligations during the period such Defaulting Bank’s L/C Obligations are cash collateralized; and

(iv) if the L/C Obligations of the Non-Defaulting Banks are reallocated pursuant to this Section 2.14(b), then the fees payable to the Banks pursuant to Section 3.1 hereof shall be adjusted to give effect to such reallocations in accordance with such Non-Defaulting Banks’ Percentages;

(c) so long as any Bank is a Defaulting Bank, no Issuing Agent shall be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the Non-Defaulting Banks (and/or cash collateralized in accordance with the terms hereof), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Banks in a manner consistent with Section 2.14(b)(i) hereof (and Defaulting Banks shall not participate therein); and

(d) any amount payable to such Defaulting Bank hereunder (whether on account of principal, interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Bank pursuant to this Agreement) shall, in lieu of being distributed to such Defaulting Bank, subject to any applicable requirements of law, be applied (i) first, to the payment of any amounts owing by such Defaulting Bank to the Administrative Agent hereunder, (ii) second, pro rata, to the payment of any amounts then owing by such Defaulting Bank to any Issuing Agent or Swing Line Bank hereunder, (iii) third, in the event such Defaulting Bank’s L/C Obligations are cash collateralized under this Section 2.14 by the Borrower, then, if no Default or Event of Default then exists, to the Borrower as a return of its corresponding cash collateral deposits until all such cash collateral has been returned to the Borrower, and (iv) fourth, to such Defaulting Bank, or, in each case, as otherwise directed by a court of competent jurisdiction.

In the event that the Administrative Agent, the Borrower, the Swing Line Bank and each Issuing Agent each agrees that a Defaulting Bank has adequately remedied all matters that caused such Bank to be a Defaulting Bank, then the Loans of the Banks shall be readjusted and reallocated to reflect the inclusion of such Bank’s Commitment and on such date such Bank shall purchase at par such of the Loans and participations in Letters of Credit and Swing Line Loans of the other Banks as the Administrative Agent shall determine may be necessary in order for such Bank to hold such Loans and participations in Letters of Credit and Swing Line Loans in accordance with its applicable Percentage after giving effect to such reallocation; provided, that, notwithstanding the foregoing, the Borrower must comply with all applicable terms hereof.

Notwithstanding anything set forth herein to the contrary, a Defaulting Bank shall not have any voting or consent rights under or with respect to any Credit Documents or constitute a “Bank” for any voting or consent rights under or with respect to any Credit Document, in any matter requiring the consent of Required Banks. Moreover, for the purposes of determining Required Banks, the Loans and Commitments held by Defaulting Banks shall be excluded from the total Loans and Commitments outstanding. For purposes of clarification, a Defaulting Bank shall not lose its right to vote with respect to matters set forth in clauses (i) and (ii) of Section 11.11 hereof.

SECTION 3. FEES.

Section 3.1 Fees.

Such Commitment Fee is payable in arrears on the last Business Day of each calendar quarter and on the Termination Date, and if the Commitments are terminated in whole prior to the Termination Date, the fee for the period to but not including the date of such termination shall be paid in whole on the date of such termination.

(ii) The letter of credit fees payable under Section 3.1(b)(i) hereof shall be due and payable quarterly in arrears on the last Business Day of each calendar quarter during which Letters of Credit are outstanding, commencing on the first such quarterly date to occur after the Effective Date, and on the Termination Date, and if the Commitments are terminated in whole on an earlier date, the fee for the period to but not including the date of such termination shall be paid in whole on the date of such termination.

(iii) The Borrower shall pay to each Issuing Agent from time to time on demand the normal issuance, presentation, amendment and other processing fees, and other standard costs and charges, of such Issuing Agent relating to Letters of Credit as from time to time in effect, and such fronting fees as may be agreed upon by the Borrower and such Issuing Agent.

All payments of principal of and interest on the Loans, and of all other Obligations and other amounts payable by the Borrower under the Credit Documents, shall be made by the Borrower in U.S. Dollars to the Administrative Agent or the applicable Issuing Agent if such payment is being made with respect to a Reimbursement

Obligation, by no later than 2:00 p.m. (New York time) on the due date thereof at the principal office of the Administrative Agent or the office of the applicable Issuing Agent designated in writing to the Borrower by such Issuing Agent, as applicable, pursuant to the payment instructions set forth on Part A of Schedule 4 hereof (or such other location in the United States as the Administrative Agent or the applicable Issuing Agent, as applicable, may designate to the Borrower) or, if such payment is on a Reimbursement Obligation, no later than provided by Section 2.2(c) hereof, in each case for the benefit of the Person or Persons entitled thereto. Any payments received after such time shall be deemed to have been received by the Administrative Agent or the applicable Issuing Agent on the next Business Day. All such payments shall be made free and clear of, and without deduction for, any set-off, defense, counterclaim, levy, or any other deduction of any kind in immediately available funds at the place of payment. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest on Loans or applicable fees ratably (except (i) with respect to repayments of Swing Line Loans, (ii) in the case of Reimbursement Obligations for which the applicable Issuing Agent has not been fully indemnified by the Banks or (iii) as otherwise specifically required hereunder) to the Banks and like funds relating to the payment of any other amount payable to any Person to such Person, in each case to be applied in accordance with the terms of this Agreement.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

The Borrower hereby represents and warrants to each Bank as to itself and, where the following representations and warranties apply to its Subsidiaries, as to each Subsidiary of the Borrower, as follows:

Section 5.1 Corporate Organization and Authority. The Borrower is duly organized and existing in good standing under the laws of the state of South Dakota; has all necessary corporate power to carry on its present business; and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing, qualification or good standing necessary and in which the failure to be so licensed, qualified or in good standing would have a Material Adverse Effect.

Section 5.2 Subsidiaries. Schedule 5.2 (as updated from time to time pursuant to Section 7.1 hereof) hereto identifies each Subsidiary of the Borrower, the jurisdiction of organization, the percentage of issued and outstanding equity securities owned by the Borrower and its Subsidiaries and, if such percentage is not one hundred percent (100%) (excluding directors’ qualifying shares as required by law), a description of each class of its equity securities and the number of securities issued and outstanding. Each Subsidiary is duly organized and existing in good standing under the laws of the jurisdiction of its organization, has all necessary corporate or equivalent power to carry on its present business, and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing or qualification necessary and in which the failure to be so licensed or qualified would have a Material Adverse Effect. All of the issued and outstanding securities of each Subsidiary owned directly or indirectly by the Borrower are validly issued and outstanding and fully paid and nonassessable except as set forth on Schedule 5.2 hereto.

All such securities owned by the Borrower are owned beneficially, and of record, free of any Lien, except as permitted in Section 7.9 hereof.

Section 5.3 Corporate Authority and Validity of Obligations. The Borrower has full right and authority to enter into this Agreement and the other Credit Documents to which it is a party, to make the borrowings herein provided for, to issue its Notes in evidence thereof, to apply (and to have applied) for the issuance of the Letters of Credit, and to perform all of its obligations under the Credit Documents to which it is a party. Each Credit Document to which it is a party has been duly authorized, executed and delivered by the Borrower and constitutes valid and binding obligations of the Borrower enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforceability of creditors’ rights generally and by equitable principles of general applicability (regardless of whether such enforceability is considered in a proceeding in equity or at law). No Credit Document, nor the performance or observance by the Borrower of any of the matters or things therein provided for, contravenes any provision of law or any charter or by-law provision of the Borrower or any material Contractual Obligation of or affecting the Borrower or any of the Borrower’s Properties or results in or requires the creation or imposition of any Lien on any of the Properties or revenues of the Borrower.

Section 5.4 Financial Statements. All financial statements heretofore delivered to the Banks showing historical performance of the Borrower for the Borrower’s fiscal years ending on or before December 31, 2010 have been prepared in accordance with generally accepted accounting principles applied on a basis consistent, except as otherwise noted therein, with that of the previous fiscal year. The unaudited balance sheet and income statements for the nine-month period ended September 30, 2011 have been prepared in accordance with generally accepted accounting principles applicable to interim financial statements applied on a basis consistent, except as otherwise noted therein, with the previous same fiscal period of the Borrower in the prior fiscal year (subject to normal year-end adjustments). Each of such financial statements fairly presents on a consolidated basis the financial condition of the Borrower and its Subsidiaries as of the dates thereof and the results of operations for the periods covered thereby. The Borrower and its Subsidiaries have no material contingent liabilities other than those disclosed in such financial statements referred to in this Section 5.4 or in comments or footnotes thereto, or in any report supplementary thereto, heretofore furnished to the Banks. Since December 31, 2010, there has been no event or series of events which has resulted in, or reasonably could be expected to result in, a Material Adverse Effect.

Section 5.5 No Litigation; No Labor Controversies.

(a) Except as disclosed on Schedule 5.5, there is no litigation or governmental proceeding pending, or to the knowledge of the Borrower, threatened, against the Borrower or any Subsidiary of the Borrower in which there is a reasonable possibility of an adverse decision which, if adversely determined, could (individually or in the aggregate) have a Material Adverse Effect.

(b) There are no labor controversies pending or, to the best knowledge of the

Borrower, threatened against the Borrower or any Subsidiary of the Borrower which could (individually or in the aggregate) have a Material Adverse Effect.

Section 5.6 Taxes. The Borrower and its Subsidiaries have timely filed all United States federal tax returns, and all other foreign, state, local and other tax returns, required to be filed and have timely paid all taxes due from the Borrower and its Subsidiaries (whether or not pursuant to such returns or pursuant to any assessment received by the Borrower or any Subsidiary of the Borrower), except such taxes, if any, as are being contested in good faith and for which adequate reserves have been provided. No notices of tax liens have been filed and no claims are being asserted concerning any such taxes, which liens or claims are material to the financial condition of the Borrower or any of its Subsidiaries (individually or in the aggregate). The charges, accruals and reserves on the books of the Borrower and its Subsidiaries for any taxes or other governmental charges are adequate and in conformance with GAAP.

Section 5.7 Approvals. No authorization, consent, approval, license, exemption, filing or registration with any court or governmental department, agency or instrumentality which have not already been obtained, nor any approval or consent of the stockholders of the Borrower or any Subsidiary of the Borrower or from any other Person, is necessary to the valid execution, delivery or performance by the Borrower or any Subsidiary of the Borrower of any Credit Document to which it is a party.

Section 5.8 ERISA. With respect to each Plan, the Borrower and each other member of the Controlled Group has fulfilled its obligations under the minimum funding standards of and is in compliance in all material respects with the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and with the Code to the extent applicable to it and has not incurred any liability to the Pension Benefit Guaranty Corporation (“PBGC”) or a Plan under Title IV of ERISA other than (a) a liability incurred in the ordinary course of business related to the ongoing funding requirements of a Plan or (b) a liability to the PBGC for premiums under Section 4007 of ERISA. Neither the Borrower nor any Subsidiary of the Borrower has any contingent liabilities for any post-retirement benefits under a Welfare Plan, other than liability for continuation coverage described in Part 6 of Title I of ERISA and Section 4980B of the Code or similar state statute.

Section 5.9 Government Regulation.

(a) Neither the Borrower nor any Subsidiary of the Borrower is an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(b) Reserved.

Section 5.10 Margin Stock; Use of Proceeds. Neither the Borrower nor any Subsidiary of the Borrower is engaged principally, or as one of its primary activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (“margin stock” to have the same meaning herein as in Regulation U of the Board of Governors of the Federal Reserve System). The proceeds of the Loans and Letters of Credit are to be used solely (i) to fund the Borrower’s working

capital needs, (ii) for general corporate purposes of the Borrower and (iii) to repay the obligations under the Existing Credit Agreement concurrently with the termination thereof. The Borrower will not use the proceeds of any Loan or Letter of Credit in a manner that violates any provision of Regulation U or X of the Board of Governors of the Federal Reserve System.

Section 5.11 Licenses and Authorizations; Compliance with Laws.

(a) The Borrower and each of its Subsidiaries has all necessary licenses, permits and governmental authorizations to own and operate its Properties and to carry on its business as currently conducted and contemplated except for any such licenses, permits and governmental authorizations which, the failure to have, could not, either individually or in the aggregate, reasonably expected to have a Material Adverse Effect. The Borrower and each of its Subsidiaries is in compliance with all applicable laws, regulations, ordinances and orders of any governmental or judicial authorities except for any such law, regulation, ordinance or order which, the failure to comply therewith, could not reasonably expected to have a Material Adverse Effect.

(b) In the ordinary course of its business, the Borrower and each of its Subsidiaries conduct annual reviews of the effect of Environmental and Health Laws on the Properties and all aspects of the business and operations of the Borrower and its Subsidiaries in the course of which the Borrower identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or contemplated closure of Properties currently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with standards imposed by law and any actual or reasonably likely liabilities to third parties, including employees or governmental entities, and any related costs and expenses). The Borrower regularly documents the results of these reviews in periodic environmental compliance audit or assessment reports (collectively, “Environmental Review Documents”). On the basis of this review, the Borrower has reasonably concluded that Environmental and Health Laws do not, and for the reasonably foreseeable future will not have, any Material Adverse Effect.

(c) Except as set forth on Schedule 5.11 (as amended from time to time in accordance with the provisions hereof): (i) the Borrower and each Subsidiary (including, without limitation, all operations and conditions at or in the Property) are and have been in compliance with all applicable Environmental and Health Laws (which compliance includes, but is not limited to, the possession by the Borrower and each of its Subsidiaries of all permits and other governmental authorizations required under applicable Environmental and Health Laws, and compliance with the terms and conditions thereof), except where failure to be in compliance could not reasonably be expected to have a Material Adverse Effect; (ii) there is no Environmental Claim pending or, to the Borrower’s knowledge, threatened against the Borrower or any of its Subsidiaries or against any Person whose liability for any Environmental Claim the Borrower or any of its Subsidiaries has retained or assumed either contractually or by operation of law, in each such case which, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect; (iii) from and after the date

on which the Borrower acquired title to the Property, there have been and are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the Release or presence of any Hazardous Material, and prior to the date on which the Borrower acquired title to the Property, to the Borrower’s knowledge, there have been and are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the Release or presence of any Hazardous Material, which, in each case, could reasonably be expected to form the basis of any Environmental Claim against the Borrower or any of its Subsidiaries, or against any Person whose liability for any Environmental Claim the Borrower or any of its Subsidiaries has retained or assumed either contractually or by operation of law, in each such case which could reasonably be expected to have a Material Adverse Effect; (iv) the Borrower and its Subsidiaries have not, and to the Borrower’s knowledge, no other Person has placed, stored, deposited, discharged, buried, dumped or disposed of Hazardous Materials on, beneath or adjacent to any property currently or formerly owned, operated or leased by the Borrower or any of its Subsidiaries, in each case, which, individually or in the aggregate, which could reasonably be expected to have a Material Adverse Effect; and (v) no Lien in favor of any Person relating to or in connection with any Environmental Claim has been filed or has been attached to any Property.

Section 5.12 Ownership of Property; Liens. The Borrower and each Subsidiary of the Borrower has good title to or valid leasehold interests in all its Property. None of the Borrower’s or any Subsidiary’s Property is subject to any Lien, except as permitted in Section 7.9 hereof.

Section 5.13 No Burdensome Restrictions; Compliance with Agreements. Neither the Borrower nor any Subsidiary of the Borrower is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any agreement to which it is a party (including any Contractual Obligation), which default could materially adversely affect the business, operations, Property or financial or other condition of the Borrower and its Subsidiaries (individually or in the aggregate).

Section 5.14 Full Disclosure. All information heretofore furnished by the Borrower to the Administrative Agent or any Bank for purposes of or in connection with the Credit Documents or any transaction contemplated thereby is, and all such information hereafter furnished by the Borrower to the Administrative Agent or any Bank will be, true and accurate in all material respects and not misleading.

(a) The Borrower will, and will cause each of its Subsidiaries to, comply in all material respects with the requirements of all Environmental and Health Laws applicable to or pertaining to the Properties or business operations of the Borrower or any Subsidiary of the Borrower. Without limiting the foregoing, the Borrower will not, and will not permit any Person to, except in accordance with applicable law, dispose of any Hazardous Material into, onto or upon any real property owned or operated by the Borrower or any of its Subsidiaries.

(b) (i) the Borrower will promptly provide the Administrative Agent with copies of Environmental Review Documents as defined in Section 5.11(b) hereof that disclose any Environmental Claim or Environmental Liability that could potentially result in a Material Adverse Effect, and in no event later than five (5) Business Days after an officer of the Borrower or a Subsidiary of the Borrower finalizes such Environmental Review Document; and (ii) the Borrower will also promptly provide the Administrative Agent with all notices and other information placing the Borrower or any of its Subsidiaries on notice of actual or potential Environmental Claims or Environmental Liabilities that could potentially result in a Material Adverse Effect.

In the event the Borrower or

any of its Subsidiaries undertakes any action with respect to the presence, Release or threatened Release of any Hazardous Materials on or affecting any Property, the Borrower or such Subsidiaries shall conduct and complete such action in material compliance with all applicable Environmental and Health Laws, and in accordance with the policies, orders and directives of all federal, state and local governmental authorities except when, and only to the extent that, the Borrower’s or such Subsidiary’s liability for such presence, handling, storage, use, disposal, transportation or Release or threatened Release of any Hazardous Materials is being diligently contested in the proper legal forum and any failure to comply during such contest will not cause a Material Adverse Effect.

(d) The Borrower agrees that the Banks may, from time to time, retain, at the Borrower’s expense for actual and reasonable out-of-pocket costs directly related thereto, an independent professional consultant reasonably acceptable to the Borrower to review the Environmental Review Documents and to conduct their own investigation (the scope of which investigation shall be reasonable based upon the circumstances) of any Property currently owned, leased, operated or used by the Borrower or any of its Subsidiaries, if (x) a Default or an Event of Default shall have occurred and be continuing, or (y) the Banks reasonably believe (1) that an occurrence relating to such Property is likely to give rise to an Environmental Liability, or (2) that a violation of an Environmental or Health Law on or around such Property has occurred or is likely to occur, which could, in the case of subclauses (1)-(2) above, reasonably be expected to have a Material Adverse Effect. The Borrower shall use its commercially reasonable efforts to obtain for the Banks and their agents, employees, consultants and contractors the right, upon reasonable notice to the Borrower, to enter into or on to the Property currently owned, leased, operated or used by the Borrower or any of its Subsidiaries to perform such tests on such property as are reasonably necessary to conduct such a review and/or investigation; provided, however, that no invasive or destructive environmental testing shall be undertaken without the Borrower’s approval, not to be unreasonably withheld, conditioned, or delayed or if recommended by the Banks’ independent consultant (except during the continuation of an Event of Default when no such approval of the Borrower shall be required). Without limiting the generality of the foregoing, any such investigation of any Property shall be conducted, unless otherwise agreed to by the Borrower and the Banks, during normal business hours and, shall be conducted so as not to unreasonably interfere with the ongoing operations at any such Property or to cause any damage or loss to any property at such Property. The Borrower and the Banks hereby acknowledge and agree that any report of any investigation conducted at the request of the Banks pursuant to this Section 7.13 will be obtained and shall be used by the Banks for the purposes of the Banks’ internal credit decisions, to monitor and police the Obligations and to protect the Banks’ security interests, if any, created by the Credit Documents, and the Banks hereby acknowledge and agree any such report will be kept confidential by them to the extent permitted by law, except that upon request, the Banks agree to deliver a copy of any such report to the Borrower. The Borrower acknowledges and agrees that (i) it will indemnify and hold harmless the Banks and their agents from any costs, losses or liabilities relating to the Borrower’s or its Subsidiaries’ use of or reliance on such report, (ii) the Banks make no representation or warranty with respect to such report, and (iii) by delivering such report to the Borrower, the Banks are not requiring or

recommending the implementation of any suggestions or recommendations contained in such report.

(e) The Borrower shall promptly notify the Banks of (i) any proposed acquisition of stock, assets, or property by the Borrower or any of its Subsidiaries; or (ii) any other proposed actions, omissions or events by or affecting the Borrower or any of its Subsidiaries, that could reasonably be expected to expose the Borrower or any of its Subsidiaries to, or otherwise result in, Environmental Liability that could reasonably be expected to have a Material Adverse Effect.

(f) The Borrower shall, at its own expense, provide copies of such documents or information as the Banks may reasonably request in relation to any matters disclosed pursuant to this Section 7.13.

The Administrative Agent, after giving notice to the Borrower pursuant to Section 8.1(c) hereof or this Section 8.2, shall also promptly send a copy of such notice to the other Banks, but the failure to do so shall not impair or annul the effect of such notice.

(b) All amounts prepaid pursuant to subsection (a) above shall be held by the

Administrative Agent in a separate collateral account (such account, and the credit balances, properties and any investments from time to time held therein, and any substitutions for such account, any certificate of deposit or other instrument evidencing any of the foregoing and all proceeds of and earnings on any of the foregoing being collectively called the “Account”) as security for, and for application by the Administrative Agent (to the extent available) to, the reimbursement of any payment under any Letter of Credit then or thereafter made by the Issuing Agents, and to the payment of the unpaid balance of any Loans and all other Obligations. The Account shall be held in the name of and subject to the exclusive dominion and control of the Administrative Agent for the benefit of the Administrative Agent, the Issuing Agents and the Banks, and the Borrower hereby grants to the Administrative Agent, for the benefit of the Administrative Agent, the Issuing Agents and the Banks, a security interest in all of the Borrower’s rights, title and interest in and to the Account and all property (including investment property) contained therein or credited thereto.

SECTION 9. CHANGE IN CIRCUMSTANCES.

Section 9.1 Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time after the date hereof any change in applicable law or regulation or in the interpretation thereof makes it unlawful for any Bank to make or continue to maintain Eurodollar Loans or to perform its obligations as contemplated hereby, such Bank shall promptly give notice thereof to the Borrower and such Bank’s obligations to make or maintain Eurodollar Loans under

this Agreement shall be suspended until it is no longer unlawful for such Bank to make or maintain Eurodollar Loans. The Borrower shall prepay on demand the outstanding principal amount of any such affected Eurodollar Loans, together with all interest accrued thereon at a rate per annum equal to the interest rate applicable to such Loan; provided, however, subject to all of the terms and conditions of this Agreement, the Borrower may then elect to borrow the principal amount of the affected Eurodollar Loans from such Bank by means of Base Rate Loans from such Bank, which Base Rate Loans shall not be made ratably by the Banks but only from such affected Bank.

Section 9.2 Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for any Borrowing of Eurodollar Loans or Daily Eurodollar Loans:

(a) the Administrative Agent determines that deposits in U.S. Dollars (in the applicable amounts) are not being offered to major banks in the eurodollar interbank market for such Interest Period, or that by reason of circumstances affecting the interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable LIBOR, or

(b) Banks having thirty-three percent (33%) or more of the aggregate amount of the Commitments reasonably determine and so advise the Administrative Agent that LIBOR as reasonably determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of funding their Eurodollar Loans or Daily Eurodollar Loans for such Interest Period,

then the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks to make Eurodollar Loans and Daily Eurodollar Loans shall be suspended.

Section 9.3 Increased Cost and Reduced Return.

(a) If, on or after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) or the Administrative Agent with any request or directive (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the relevant jurisdiction) of any such authority, central bank or comparable agency, including, notwithstanding the foregoing, all requests, rules, guidelines or directives (x) in connection with the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act or (y) promulgated by the Bank for International Settlements, the Basel Committee on Banking Regulations and Supervisory Practices (or any successor or similar authority) or the United States financial regulatory authorities, in each case of clauses (x) and (y), regardless of the date enacted, adopted, issued, promulgated or implemented:

(i) shall subject any Bank (or its Lending Office) or the Administrative Agent to any tax, duty or other charge with respect to its Loans, its Notes, its Letter(s) of Credit, or its participation in any thereof, any Reimbursement Obligations owed to it or its obligation to make Loans, issue a Letter of Credit, or to participate therein, or shall change the basis of taxation of payments to any Bank (or its Lending Office) or the Administrative Agent of the principal of or interest on its Loans, Letter(s) of Credit, or participations therein or any other amounts due under this Agreement in respect of its Loans, Letter(s) of Credit, or participations therein, any Reimbursement Obligations owed to it, or its obligation to make Loans, issue a Letter of Credit, or acquire participations therein (except for changes in the rate of tax on the overall net income or profits of such Bank or its Lending Office or the Administrative Agent imposed by the jurisdiction in which such Bank or its Lending Office or the Administrative Agent is incorporated or in which such Bank’s principal executive office or Lending Office or the Administrative Agent is located); or

(ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding with respect to any Eurodollar Loans or Daily Eurodollar Loans any such requirement included in an applicable Eurodollar Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Lending Office) or shall impose on any Bank (or its Lending Office) or on the interbank market any other condition affecting its Eurodollar Loans, its Daily Eurodollar Loans, its Notes, its Letter(s) of Credit, or its participation in any thereof, any Reimbursement Obligation owed to it, or its obligation to make Eurodollar Loans or Daily Eurodollar Loans, to issue a Letter of Credit, or to participate therein;

and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) or the Administrative Agent of making or maintaining any Loan, issuing or maintaining a Letter of Credit, or participating therein, or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) or the Administrative Agent under this Agreement or under its Notes with respect thereto, by an amount deemed by such Bank or the Administrative Agent to be material, then, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent) or the Administrative Agent, the Borrower shall be obligated to pay to such Bank or the Administrative Agent such additional amount or amounts as will compensate such Bank or the Administrative Agent for such increased cost or reduction. In the event any law, rule, regulation or interpretation described above is revoked, declared invalid or inapplicable or is otherwise rescinded, and as a result thereof a Bank or the Administrative Agent is determined to be entitled to a refund from the applicable authority for any amount or amounts which were paid or reimbursed by the Borrower to such Bank or the Administrative Agent hereunder, such Bank or the Administrative Agent shall refund such amount or amounts to the Borrower without interest.

(b) If, after the date hereof, any Bank or the Administrative Agent shall have determined that the adoption of any applicable law, rule or regulation regarding capital

adequacy or liquidity requirements, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; ▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇ ▇) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital or liquidity rules heretofore adopted and issued by any governmental authority), or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive regarding capital adequacy or liquidity (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the applicable jurisdiction) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Bank’s capital, or on the capital of any corporation controlling such Bank, as a consequence of its obligations hereunder to a level below that which such Bank could have achieved but for such adoption, change or compliance (taking into consideration such Bank’s policies with respect to capital adequacy and liquidity) by an amount deemed by such Bank to be material, then from time to time, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction.

(c) Each Bank that determines to seek compensation under this Section 9.3 shall notify the Borrower and the Administrative Agent of the circumstances that entitle the Bank to such compensation pursuant to this Section 9.3 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 sole judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section 9.3 and setting forth the additional amount or amounts to be paid to it hereunder submitted to the Borrower and the Administrative Agent by such Bank in good faith shall be prima facie evidence of the amount of such compensation. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

Section 9.4 Lending Offices. Each Bank may, at its option, elect to make its Loans hereunder at the branch, office or affiliate specified in its respective Administrative Questionnaire or in the assignment agreement which any assignee bank executes pursuant to Section 11.12 hereof (each a “Lending Office”) for each type of Loan available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice to the Borrower and the Administrative Agent, so long as such election does not increase costs or other amounts payable by the Borrower to such Bank hereunder.

Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding any other provision of this Agreement, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit; it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Bank had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the eurodollar interbank

market having a maturity corresponding to such Loan’s Interest Period and bearing an interest rate equal to LIBOR for such Interest Period.

SECTION 10. THE AGENT.

Section 10.1 Appointment and Authorization of Administrative Agent. Each Bank hereby appoints U.S. Bank National Association as the Administrative Agent under the Credit Documents and hereby authorizes the Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the other Credit Documents. The Administrative Agent is acting pursuant to a contractual relationship on an arm’s length basis and the duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Bank, the holder of any Note or any other Person; and nothing in this Agreement or any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein.

Section 10.2 Administrative Agent and its Affiliates. The Administrative Agent shall have the same rights and powers under this Agreement and the other Credit Documents as any other Bank and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and the Administrative Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Affiliate of the Borrower as if it were not the Administrative Agent under the Credit Documents.

Section 10.3 Action by Administrative Agent. If the Administrative Agent receives from the Borrower a written notice of an Event of Default pursuant to Section 7.6(d)(i) hereof, the Administrative Agent shall promptly give each of the Banks written notice thereof. The obligations of the Administrative Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action hereunder with respect to any Default or Event of Default, except as expressly provided in Sections 8.2 and 8.3 hereof. In no event, however, shall the Administrative Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it shall be first indemnified to its reasonable satisfaction by the Banks against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall be entitled to assume that no Default or Event of Default exists unless notified to the contrary in writing by a Bank or the Borrower. In all cases in which this Agreement and the other Credit Documents do not require the Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in

using its discretion in failing to take or in taking any action hereunder and thereunder.

Section 10.4 Consultation with Experts. The Administrative Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

Section 10.5 Liability of Administrative Agent; Credit Decision. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or not taken by it in connection with the Credit Documents (i) with the consent or at the request of the Required Banks, or (ii) in the absence of its own gross negligence or willful misconduct (as proven by the final, non-appealable judgment of a court of competent jurisdiction). Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement, any other Credit Document or any Credit Event; (ii) the performance or observance of any of the covenants or agreements of the Borrower or any other party contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in Section 6 hereof; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectibility hereof or of any other Credit Document or of any other documents or writing furnished in connection with any Credit Document; and the Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. The Administrative Agent may execute any of its duties under any of the Credit Documents by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, the Borrower, or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, the Administrative Agent shall have no responsibility for confirming the accuracy of any Compliance Certificate or other document or instrument received by it under the Credit Documents. The Administrative Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with the Administrative Agent signed by such payee in form satisfactory to the Administrative Agent. Each Bank acknowledges that it has independently and without reliance on the Administrative Agent or any other Bank, and based upon such information, investigations and inquiries as it deems appropriate, made its own credit analysis and decision to extend credit to the Borrower in the manner set forth in the Credit Documents. It shall be the responsibility of each Bank to keep itself informed as to the creditworthiness of the Borrower and any other relevant Person, and the Administrative Agent shall have no liability to any Bank with respect thereto.

Section 10.6 Indemnity. The Banks shall ratably, in accordance with their respective Percentages, indemnify and hold the Administrative Agent, and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent the Administrative

Agent is promptly reimbursed for the same by the Borrower and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Banks under this Section 10.6 shall survive termination of this Agreement.

Section 10.7 Resignation of Administrative Agent and Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and the Borrower. Upon any such resignation of the Administrative Agent, the Required Banks shall have the right to appoint a successor Administrative Agent with the consent of the Borrower. If no successor Administrative Agent shall have been so appointed by the Required Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be any Bank or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of its appointment as the Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent under the Credit Documents, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder; provided, if the Administrative Agent shall notify the Borrower and the Banks 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, (2) all payments (other than agency fees (as defined in the Fee Letters), communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Bank directly, until such time as the Required Banks appoint a successor Administrative Agent as provided for above and (3) the agency fees shall be waived for the period from the effective date of the resignation of the resigning Administrative Agent until the effective date of the appointment of its successor. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 10 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent.

SECTION 11. MISCELLANEOUS.

Section 11.1 Withholding Taxes.

(a) Payments Free of Withholding. Subject to Section 11.1(b) hereof, each payment by the Borrower under this Agreement or the other Credit Documents shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient imposed by the jurisdiction in which the recipient is organized or conducts business (other than any jurisdiction in which the recipient is deemed to conduct business solely as the result of entering into this Agreement or any other Credit Document or receiving any payment or taking any action thereunder) and taxes imposed by FATCA). If any such withholding is so required, the Borrower shall make the withholding, pay the amount withheld to the appropriate governmental authority before penalties attach

thereto or interest accrues thereon and, except with respect to taxes imposed by FATCA, forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Bank and the Administrative Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Bank or the Administrative Agent (as the case may be) would have received had such withholding not been made. If the Administrative Agent or any Bank pays any amount in respect of any such taxes, penalties or interest (other than taxes, penalties or interest imposed by FATCA), the Borrower shall reimburse the Administrative Agent or that Bank for that payment on demand in the currency in which such payment was made. If the Borrower pays any such taxes, penalties or interest, it shall deliver official tax receipts evidencing that payment or certified copies thereof to the Bank or the Administrative Agent on whose account such withholding was made (with a copy to the Administrative Agent if not the recipient of the original) on or before the thirtieth day after payment. If any Bank or the Administrative Agent determines it has received or been granted a credit against or relief or remission for, or repayment of, any taxes paid or payable by it because of any taxes, penalties or interest paid by the Borrower and evidenced by such a tax receipt, such Bank or the Administrative Agent shall, to the extent it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as such Bank or the Administrative Agent determines is attributable to such deduction or withholding and which will leave such Bank or the Administrative Agent (after such payment) in no better or worse position than it would have been in if the Borrower had not been required to make such deduction or withholding. Nothing in this Agreement shall interfere with the right of each Bank and the Administrative Agent to arrange its tax affairs in whatever manner it thinks fit nor obligate any Bank or the Administrative Agent to disclose any information relating to its tax affairs or any computations in connection with such taxes, other than the information required to be disclosed pursuant to Section 11.1(d) hereof.

(b) U.S. Withholding Tax Exemptions. Each Bank that is not a “United States person” (as such term is defined in Section 7701(a)(30) of the Code) shall submit to the Borrower and the Administrative Agent on or before the date of the initial Borrowing hereunder two duly completed and signed copies of either Form W-8BEN or Form W-8ECI of the United States Internal Revenue Service. Thereafter and from time to time, each such Bank shall submit to the Borrower and the Administrative Agent such additional duly completed and signed copies of one or the other of such Forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) requested by the Borrower in a written notice, directly or through the Administrative Agent, to such Bank and (ii) required under then current United States law or regulations to avoid or reduce United States federal withholding taxes on payments in respect of all amounts to be received by such Bank, including fees, pursuant to the Credit Documents or the Loans.

(c) Inability of Bank to Submit Forms. If any Bank determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to the Borrower or the Administrative Agent any form or certificate that such Bank is obligated to submit pursuant to subsection (b) or

(d) of this Section 11.1 or that such Bank is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Bank shall promptly notify the Borrower and the Administrative Agent of such fact and the Bank shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable.

(d) FATCA Forms. If a payment made to a Bank under any Credit Document would be subject to U.S. federal withholding tax imposed by FATCA if such Bank were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Bank shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Bank has complied with such Bank’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this subsection (d), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Section 11.2 No Waiver of Rights. No delay or failure on the part of the Administrative Agent or any Bank or on the part of the holder or holders of any Note in the exercise of any power or right under any Credit Document shall operate as a waiver thereof, nor as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power or right, and the rights and remedies hereunder of the Administrative Agent, the Banks and the holder or holders of any Notes are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have.

Section 11.3 Non-Business Day. If any payment of principal or interest on any Loan or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such Loan or other Obligation bears for the period prior to maturity shall continue to accrue on such Obligation from the stated due date thereof to and including the next succeeding Business Day, on which the same shall be payable.

Section 11.4 Documentary Taxes. The Borrower agrees that it will pay any documentary, stamp or similar taxes payable in respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any credit is then in use or available hereunder.

Section 11.5 Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date

as of which they were made as long as any credit is in use or available hereunder.

Section 11.6 Survival of Indemnities. All indemnities and all other provisions relative to reimbursement to the Banks of amounts sufficient to protect the yield of the Banks with respect to the Loans, including, but not limited to, Section 2.11, Section 9.3 and Section 11.13 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations.

Section 11.7 Set-Off.

(a) In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of any Event of Default, each Bank and each subsequent holder of any Note is hereby authorized by the Borrower at any time or from time to time, without notice to the Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, or otherwise fully matured, and in whatever currency denominated) and any other Indebtedness at any time held or owing by that Bank or that subsequent holder to or for the credit or the account of the Borrower, whether or not matured, against and on account of the obligations and liabilities of the Borrower to that Bank or that subsequent holder under the Credit Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Credit Documents, irrespective of whether or not (a) that Bank or that subsequent holder shall have made any demand hereunder or (b) the principal of or the interest on the Loans or Notes and other amounts due hereunder shall have become due and payable pursuant to Section 8 hereof and although said obligations and liabilities, or any of them, may be contingent or unmatured.

(b) Each Bank agrees with each other Bank a party hereto that if such Bank shall receive and retain any payment, whether by set-off or application of deposit balances or otherwise, on any of the Loans or Reimbursement Obligations in excess of its ratable share of payments on all such obligations then outstanding to the Banks, then such Bank shall purchase for cash at face value, but without recourse, ratably from each of the other Banks such amount of the Loans or Reimbursement Obligations, or participations therein, held by each such other Banks (or interest therein) as shall be necessary to cause such Bank to share such excess payment ratably with all the other Banks; provided, however, that if any such purchase is made by any Bank, and if such excess payment or part thereof is thereafter recovered from such purchasing Bank, the related purchases from the other Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest. For purposes of this Section 11.7(b), amounts owed to or recovered by, an Issuing Agent in connection with Reimbursement Obligations in which Banks have been required to fund their participation shall be treated as amounts owed to or recovered by such Issuing Agent as a Bank hereunder.

Section 11.8 Notices. Except as otherwise specified herein, all notices under the Credit

Documents shall be in writing (including facsimile or other electronic communication) and shall be given to a party hereunder at its address or facsimile number set forth below or such other address or facsimile number as such party may hereafter specify by notice to the Administrative Agent and the Borrower, given by courier, by United States certified or registered mail, or by other telecommunication device capable of creating a written record of such notice and its receipt. Notices under the Credit Documents to the Banks shall be addressed to their respective addresses, facsimile or telephone numbers set forth on their respective Administrative Questionnaires or in the assignment agreement which any assignee bank executes pursuant to Section 11.12 hereof, and to the Borrower and to the Administrative Agent to:

counterpart signature pages, and by the different parties on different counterparts, each of which when executed shall be deemed an original but all such counterparts taken together shall constitute one and the same instrument. Delivery of an executed counterpart hereof via facsimile or electronic means shall for all purposes be as effective as delivery of an original counterpart.

Section 11.10 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign any of its rights or obligations under any Credit Document unless such assignation occurs in connection with a merger or acquisition by the Borrower which is otherwise permitted under the terms of this Agreement and the appropriate Credit Documents, if applicable, and the Borrower obtains the prior written consent of all of the Banks, which consent shall be in form and substance satisfactory to the Administrative Agent. No Bank may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (g) 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 paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Banks. Any Bank 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 at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning Bank’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Bank or an Affiliate of a Bank or an Approved Fund with respect to a Bank, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loan of the assigning Bank 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 and, so long as no Event of Default has occurred and is continuing, the Borrower, otherwise consents (each such consent not to be unreasonably withheld or delayed);

(ii) each partial assignment shall be made as an assignment of a

proportionate part of all the assigning Bank’s rights and obligations under this Agreement with respect to the Loan, L/C Obligations or the Commitment assigned;

(iii) any assignment of a Commitment must be approved by (i) the Administrative Agent (not to be unreasonably withheld) and the Issuing Agents and (ii) unless the Person that is the proposed assignee is itself a Bank with a Commitment or an Affiliate of a Bank (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee) and/or an Event of Default has occurred and is continuing, the Borrower (not to be unreasonably withheld); provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; 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 of $3,500, and the Eligible Assignee, if it shall not be a Bank, shall deliver to the Administrative Agent an Administrative Questionnaire and any relevant tax forms.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (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 Bank under this Agreement, and the assigning Bank 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 Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 9.3 and 9.4 hereof with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with paragraph (d) of this Section. The Borrower shall execute and deliver to the assignee a Note upon written request from such assignee. The assignor shall promptly return to the Borrower its Note if after giving effect to such assignment such assignor has no Commitment and no Obligations are owing to such assignor.

(c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Banks, and the Commitments of, and principal amounts of the Loans owing to, each Bank 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 Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement,

notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and, as to its commitments only, any Bank, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Bank 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 Bank’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Bank’s obligations under this Agreement shall remain unchanged, (ii) such Bank 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 Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Each Bank that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in such Bank’s Loans or other obligations under this Agreement (the “Participant Register”); provided that no Bank shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant's interest in any Commitments, Loans or its other obligations under any this Agreement) except to the extent that such disclosure is necessary to establish that such Commitment, Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Bank shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

(e) Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that such Bank 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 Bank will not, without the consent of the Participant, agree to any amendment, modification or waiver of the type described in Section 11.11(i) hereof that affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 9.3 and 9.4 hereof to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.7(a) hereof as though it were a Bank, provided such Participant agrees to be subject to Section 11.7(b) hereof as though it were a Bank.

(f) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 9.3 and 9.4 hereof than the applicable Bank 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 Bank if it were a Bank shall not be entitled to the benefits of Section 9.4 hereof 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 9.4 hereof as though it were a Bank.

(g) Certain Pledges. Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central banking authority; provided that no such pledge or assignment shall release such Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Bank as a party hereto.

(h) Certain Funding Arrangements. Notwithstanding anything to the contrary contained herein, any Bank (a “Granting Bank”) may grant to a special purpose funding vehicle which is an Affiliate of such Bank (a “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Bank would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Bank shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Loan were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 11.10, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Bank or to any financial institutions (consented to by the Borrower and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section may not be amended without the written consent of the SPC.

(i) Farm Credit System. Notwithstanding anything in this Section to the contrary, any bank that is a member of the Farm Credit System that: (x) has purchased a

participation in the minimum amount of $10,000,000 on or after the Effective Date, (y) is, by written notice to the Borrower and the Administrative Agent (“Voting Participant Notification”), designated by the selling Bank as being entitled to be accorded the rights of a Voting Participant hereunder (any bank that is a member of the Farm Credit System so designated being called a “Voting Participant”) and (z) receives the prior written consent of the Borrower and the Administrative Agent to become a Voting Participant, shall be entitled to vote (and the voting rights of the selling Bank shall be correspondingly reduced), on a dollar for dollar basis, as if such participant were a Bank, on any matter requiring or allowing a Bank to provide or withhold its consent, or to otherwise vote on any proposed action. To be effective, each Voting Participant Notification shall, with respect to any Voting Participant: (i) state the full name, as well as all contact information required of an Assignee as set forth in Exhibit D hereto and (ii) state the dollar amount of the participation purchased. The Borrower and the Administrative Agent shall be entitled to conclusively rely on information contained in notices delivered pursuant to this paragraph.

Section 11.11 Amendments. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Borrower, (b) the Required Banks, (c) if the rights or duties of the Administrative Agent are affected thereby, the Administrative Agent, (d) if the rights or duties of any Issuing Agent are affected thereby, such Issuing Agent and (e) if the rights or duties of the Swing Line Bank are affected thereby, the Swing Line Bank; provided that no amendment or waiver pursuant to this Section 11.11 shall:

(i) (A) increase, decrease or extend any Commitment of any Bank without the consent of such Bank or (B) reduce the amount of or postpone any fixed date for payment of any principal of or interest on any Loan or Reimbursement Obligation (including the Termination Date) or of any fee or other Obligation payable hereunder without the consent of each Bank; and

(ii) unless signed by each Bank, change this Section 11.11, or the definition of Required Banks, or affect the number of Banks required to take any action under the Credit Documents or, with respect to the pro rata sharing of payments, amend Section 4.1 hereof or any other provision hereof relating to the pro rata sharing of payments.

waiver or consent related hereto, whether or not the transactions contemplated herein are consummated. The Borrower further agrees to indemnify each Bank, the Administrative Agent, the Swing Line Bank and the Issuing Agents, and their respective Affiliates, directors, agents, advisors, officers and employees, against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor, whether or not the indemnified Person is a party thereto, and whether brought by a third-party or by the Borrower or any of its Affiliates) which any of them may incur or reasonably pay arising out of or relating to any Credit Document (including any relating to a misrepresentation by the Borrower under any Credit Document) or any of the transactions contemplated thereby or the direct or indirect application or proposed application of the proceeds of any Loan or Letter of Credit, other than to the extent arising from the gross negligence or willful misconduct of the party claiming indemnification as determined in a final, non-appealable judgment by a court of competent jurisdiction. The Borrower, upon demand by any of the Administrative Agent, the Swing Line Bank, an Issuing Agent or a Bank at any time, shall reimburse the Administrative Agent, the Swing Line Bank, such Issuing Agent or Bank for any reasonable legal or other expenses (including allocable fees and expenses of in-house counsel) incurred in connection with investigating or defending against any of the foregoing except if the same is directly due to the gross negligence or willful misconduct of the party to be indemnified as determined in a final, non-appealable judgment by a court of competent jurisdiction, provided that with respect to legal costs and expenses incurred in connection with the enforcement of the rights of the Administrative Agent, the Swing Line Bank, each Issuing Agent and the Banks under this Section 11.13, the Borrower shall only be obligated to pay the legal fees of the Administrative Agent and not of any Issuing Agent or other Bank.

Section 11.14 Entire Agreement. The Credit Documents constitute the entire understanding of the parties thereto with respect to the subject matter thereof and any prior or contemporaneous agreements, whether written or oral, with respect thereto are superseded thereby.

Section 11.15 Construction.

THE BORROWER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

Section 11.18 Replacement of Bank. Each Bank agrees that, upon the occurrence of any event set forth in Sections 9.1, 9.3 and 11.1 hereof, such Bank will use reasonable efforts to book and maintain its Loans through a different Lending Office or to transfer its Loans to an Affiliate with the objective of avoiding or minimizing the consequences of such event; provided that such booking or transfer is not otherwise disadvantageous to such Bank as determined by such Bank in its sole and absolute discretion. If any Bank has demanded to be paid additional amounts pursuant to Sections 9.1, 9.3 and 11.1 hereof, and the payment of such additional amounts are, and are likely to continue to be, more onerous in the reasonable judgment of the Borrower than with respect to the other Banks, then the Borrower shall have the right at any time when no Default or Event of Default shall have occurred and be continuing to seek one or more financial institutions which are not Affiliates of the Borrower (each, a “Replacement Bank”) to purchase with the written consent of the Administrative Agent (which consent shall not be (x) required if such proposed Replacement Bank is already a Bank, or an Affiliate of a Bank, or (y) unreasonably delayed or withheld) the outstanding Loans and Commitments of such Bank (the “Affected Bank”), and if the Borrower locates a Replacement Bank, the Affected Bank shall, upon


i.	prior written notice to the Administrative Agent,

ii.

(i) payment to the Affected Bank of the purchase price agreed between it and the Replacement Bank (or, failing such agreement, a purchase price in the amount of the outstanding principal amount of the Affected Bank’s Loans and accrued interest thereon to the date of payment) by the Replacement Bank plus (ii) payment by the Borrower of all Obligations (other than principal and interest with respect to Loans) then due to the Affected Bank or accrued for its account hereunder or under any other Credit Document,


iii.	satisfaction of the provisions set forth in Section 11.10 hereof, and


iv.	payment by the Borrower to the Affected Bank and the Administrative Agent of all reasonable out-of-pocket expenses in connection with such assignment and assumption (including the recordation fee described in Section 11.10 hereof),

be deemed without any further action to have assigned and delegated all its rights and obligations under this Agreement and any other Credit Document to which it is a party (including its outstanding Loans) to the Replacement Bank (such assignment to be made without recourse, representation or warranty), and the Replacement Bank shall assume such rights and obligations, whereupon the Replacement Bank shall in accordance with Section 11.10 hereof become a party to each Credit Document to which the Affected Bank is a party and shall have the rights and obligations of a Bank thereunder and the Affected Bank shall be released from its obligations hereunder and each other Credit Document to the extent of such assignment and delegation.

Notwithstanding the foregoing, with respect to a Bank that is a Defaulting Bank or an Impacted Bank, the Borrower or the Administrative Agent may obtain a Replacement Bank and execute an Assignment on behalf of such Defaulting Bank or an Impacted Bank at any time and without prior notice to such Defaulting Bank or an Impacted Bank and cause its Loans and Commitments to be sold and assigned at par. Upon any such assignment and payment and compliance with the other provisions of Section 11.10 hereof, such replaced Bank shall no longer constitute a “Bank” for purposes hereof; provided, any rights of such replaced Bank to indemnification hereunder shall survive.

Section 11.19 Confidentiality. The Administrative Agent and the Banks shall hold all non-public information provided to them by the Borrower pursuant to or in connection with this Agreement in accordance with their customary procedures for handling confidential information of this nature, but may make disclosure to any of their agents, attorneys-in-fact, examiners, regulators, non-governmental self-regulatory authorities, Affiliates, outside auditors, counsel and other professional advisors in connection with this Agreement or any other Credit Document or as reasonably required by any potential bona fide transferee, participant or assignee, or in connection with the exercise of remedies under a Credit Document, or to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section 11.19), or to any nationally recognized rating agency that requires access to information about a Bank’s investment portfolio in connection with ratings issued with respect to such Bank, or as requested by any governmental agency, non-governmental self-regulatory authority or representative thereof or pursuant to legal or regulatory process; provided, however, that unless specifically prohibited by applicable law or court order, or in connection with any supervising examination, the Administrative Agent and each Bank shall use reasonable efforts to promptly notify the Borrower of any request by any governmental agency or representative thereof (other than any such request in connection with an examination of the financial condition of the Administrative Agent or such Bank by such governmental agency) for disclosure of any such non-public information and, where practicable, prior to disclosure of such information. Prior to any such disclosure pursuant to this Section 11.19, the Administrative Agent and each Bank shall require any such bona fide transferee, participant and assignee receiving a disclosure of non-

public information to agree, for the benefit of the Borrower, in writing to be bound by this Section 11.19; and to require such Person to require any other Person to whom such Person discloses such non-public information to be similarly bound by this Section 11.19.

Notwithstanding anything herein to the contrary, “confidential information” shall not include, and the Administrative Agent and each Bank may disclose to any and all persons, without limitation of any kind, (i) any information with respect to the U.S. federal income tax treatment and U.S. federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such Bank relating to such tax treatment and tax structure, (ii) information that has been publicly disclosed or has become public without breach of this Section 11.19 and (iii) information that now or hereafter becomes available to such Bank on a non-confidential basis from a source other than the Borrower.

Section 11.20 Rights and Liabilities of Co-Syndication Agents, Co-Documentation Agents and Arrangers. Neither any Co-Syndication Agent, any Co-Documentation Agent nor any Arranger has any special rights, powers, obligations, liabilities, responsibilities or duties under this Agreement as a result of acting in the capacity of Co-Syndication Agent, Co-Documentation Agent or Arranger, as applicable, other than those applicable to them in their capacity as Banks hereunder (if any). Without limiting the foregoing, neither any Co-Syndication Agent, any Co-Documentation Agent nor any Arranger shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the same acknowledgments and undertakings with respect to each Co-Syndication Agent, each Co-Documentation Agent and each Arranger as it makes with respect to the Administrative Agent and any directors, officers, agents and employees of the Administrative Agent in Section 10.5 hereof.

Section 11.21 Relationship. Neither the Administrative Agent, any Issuing Agent, the Swing Line Bank nor any Bank has any fiduciary relationship or duty to the Borrower or any of its Subsidiaries arising out of or in connection with, and there is no agency, tenancy or joint venture relationship between the Administrative Agent, any Issuing Agent, the Swing Line Bank or any Bank and the Borrower or any of its Subsidiaries by virtue of, any Credit Document or any transaction contemplated therein.

The Borrower and each of its Subsidiaries understand that the Administrative Agent, the Issuing Agents, the Swing Line Bank, each Bank and their respective affiliates (the Administrative Agent or such Bank, as the case may be, together with its affiliates, each referred to herein as a “Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research). Members of each Group and businesses within each Group generally act independently of each other, both for their own account and for the account of clients. Accordingly, there may be situations where parts of a Group and/or their clients either now have or may in the future have interests, or take actions, that may conflict with the interests of the Borrower or one of its Subsidiaries. For example, a Group may, in the ordinary course of business, engage in trading in financial products or undertake other investment businesses for their own account or on behalf of other clients,

including without limitation, trading in or holding long, short or derivative positions in securities, loans or other financial products of the Borrower, its Subsidiaries or its affiliates or other entities connected with the Loans or the transactions contemplated hereby.

In recognition of the foregoing, the Borrower, for itself and on behalf of its Subsidiaries, agrees no Group is required to restrict its activities as a result of this Agreement and that each Group may undertake any business activity without further consultation with or notification to the Borrower or any of its Subsidiaries. Neither this Agreement nor the receipt by the Administrative Agent, any Issuing Agent, the Swing Line Bank or any Bank of confidential information nor any other matter will give rise to any fiduciary, equitable or contractual duties (including but not limited to any duty of trust or confidence) that would prevent or restrict a Group from acting on behalf of other customers or for its own account. Furthermore, the Borrower, for itself and on behalf of its Subsidiaries, agrees that no Group and no member or business of a Group is under a duty to disclose to the Borrower or any of its Subsidiaries or use on behalf of the Borrower or any of its Subsidiaries any information whatsoever about or derived from those activities or to account for any revenue or profits obtained in connection with such activities. However, consistent with each Group’s long-standing policy to hold in confidence the affairs of its customers, no Group will use confidential information obtained from the Borrower or any of its Subsidiaries except in connection with its services to, and its relationship with, the Borrower and its Subsidiaries; provided, that each Group will be free to disclose information in any manner as required by law, regulation, regulatory authority or other applicable judicial or government order.

Section 11.22 [Reserved.].Severability of Provisions

Section 11.24 Patriot Act Notice. Each Bank that is subject to the Patriot Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Bank) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act (Title III of Pub. L. 107‑56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act.

Level I Status	17.5	125	25	125

Level III Status	25	150	50	150
Level IV Status	35	175	75	175
Level V Status	45	225	125	225

The Reference Rating is initially determined (i) in the case of Base Rate Loans, on the Effective Date, and (ii) in the case of any Eurodollar Loans, on the second Business Day prior to the borrowing of such Eurodollar Loans. Changes in the Applicable Margin resulting from a change in the Category shall become effective on the fifth Business Day after the effective date of any change in the Reference Rating from S&P or ▇▇▇▇▇’▇.

If the Reference Rating is unavailable as of the date any determination of the Applicable Margin is to occur, the Borrower and the Banks will negotiate in good faith to agree on an alternative method for establishing the Applicable Margin for any affected Advances. Until the earlier of (i) the time at which such an alternative method is agreed upon or (ii) 30 days after the date on which the Reference Rating became unavailable (such 30-day period, the “Negotiation Period”), the interest payable per annum with respect to Eurodollar Loans and Base Rate Loans (to the extent the Applicable Margin thereon is greater than zero) in the affected borrowing will be based upon the Applicable Margin calculated using the last available quote of the Reference Rating.

In the event of split ratings, the Commitment Fee, Letter of Credit Fees, and Applicable Margin will be based upon the lower rating unless the ratings differ by more than one Category, in which case the Commitment Fee, Letter of Credit Fees and Applicable Margin will be based upon the Category one level above the Category corresponding to the lower rating.
