NOW, THEREFORE, in consideration of the premises and the agreements hereinafter set forth, the parties hereto hereby agree as follows:

“Administrative Agent”: as defined in the preamble hereto.

“Affiliate”: as to any Person, any other Person that, directly or indirectly, is in control of, is controlled by, or is under common control with, such Person. For purposes of this definition, “control” of a Person means the power, directly or indirectly, either to (a) vote 10% or more of the securities having ordinary voting power for the election of directors (or persons performing similar functions) of such Person or (b) direct or cause the direction of the management and policies of such Person, whether by contract or otherwise.

“Agents”: the collective reference to the Syndication Agent, the Administrative Agent and the Co-Documentation Agents.

“Aggregate Exposure”: with respect to any Lender at any time, an amount equal to (a) until the Closing Date, the aggregate amount of such Lender's Commitments at such time and (b) thereafter, the amount of such Lender's Revolving Credit Commitment then in effect or, if the Revolving Credit Commitments have been terminated, the amount of such Lender's Revolving Extensions of Credit then outstanding.

“Aggregate Exposure Percentage”: with respect to any Lender at any time, the ratio (expressed as a percentage) of such Lender's Aggregate Exposure at such time to the sum of the Aggregate Exposures of all Lenders at such time.

“Applicable Percentage”: means with respect to any Lender at any time, the percentage (carried

out to the ninth decimal place) of the aggregate Commitments represented by such Lender's Commitment at such time, subject to adjustment as provided in Section 2.21. If the Commitment of each Lender to make Loans and the obligation of the Issuing Lender to make L/C Credit Extensions have been terminated pursuant to Section 8 or if the aggregate Commitments have expired, then the Applicable Percentage of each Lender shall be determined based on the Applicable Percentage of such Lender most recently in effect, giving effect to any subsequent assignments. The initial Applicable Percentage of each Lender is set forth opposite the name of such Lender on the Commitment Appendix or in the assignment and acceptance pursuant to which such Lender becomes a party hereto, as applicable.

“Application”: an application, in such form as the relevant Issuing Lender may specify from time to time, requesting such Issuing Lender to issue a Letter of Credit.

“Assignee”: as defined in Section 10.6(c).

“Assignor”: as defined in Section 10.6(c).

“Available Revolving Credit Commitment”: with respect to any Revolving Credit Lender at any time, an amount equal to the excess, if any, of (a) such Lender's Revolving Credit Commitment then in effect over (b) such Lender's Revolving Extensions of Credit then outstanding.

“Bank of America Entity”: any of Bank of America, N.A. or any of its Affiliates.

“Base Rate”: for any day, a rate per annum (rounded upwards, if necessary, to the next 1/100 of 1%) equal to the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such day plus ½ of 1% and (c) the Eurodollar Rate for a one month Interest Period on such day (or if such day is not a Business Day, the immediately preceding Business Day) plus 1%; provided that, for the avoidance of doubt, the Eurodollar Rate for any day shall be based on the rate appearing on the Reuters Screen LIBOR01 Page (or any successor page) at approximately 11:00 a.m. London time on such day. For purposes hereof: “Prime Rate” shall mean the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its “prime rate” (the “prime rate” is a rate set by Bank of America based upon various factors including Bank of America's costs and desired return, general economic conditions and other factors, and is used as a reference point for pricing some loans, which may be priced at, above, or below such announced rate). Any change in the Base Rate due to a change in the Eurodollar Rate, the Prime Rate or the Federal Funds Effective Rate shall be effective as of the opening of business on the effective day of such change in Eurodollar Rate, the Prime Rate or the Federal Funds Effective Rate, respectively.

(b)So long as any Lender is a Defaulting Lender, no Swing Line Lender shall be required to make a Swing Line Loan, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders (by re-allocation among non-Defaulting Lenders (without the participation of such Defaulting Lender therein) as provided in Section 2.21(a)(iv)) and/or by Cash Collateral provided by such Defaulting Lender (and/or by the Borrower in accordance with Section 2.22(a)).

4.Procedure for Swing Line Borrowing; Refunding of Swing Line Loans. (a) The Borrower may borrow under the Swing Line Commitment on any Business Day during the Revolving Credit Commitment Period; provided, the Borrower shall give to a Swing Line Lender irrevocable telephonic notice confirmed promptly in writing to such Swing Line Lender with a copy thereof to be provided to the Administrative Agent (and each other Swing Line Lender)(which telephonic notice must be received by such Swing Line Lender not later than 1:00 P.M., New York City time, on the proposed Borrowing Date), specifying (i) the amount to be borrowed, (ii) the requested Borrowing Date, (iii) the maturity date thereof (which, in the case of a Eurodollar Loan, shall be the last day of the applicable Interest Period) and (iv) whether such Swing Line Loan will be a Eurodollar Loan, a Base Rate Loan or a Money Market Rate Loan. Each borrowing under the Swing Line Commitment shall be in an amount equal to $500,000 or a whole multiple of $100,000 in excess thereof. In no event shall the number of Swing Line Loans outstanding at any time be greater than five. The Borrower may, on any Borrowing Date for Swing Line Loans and prior to 11:00 A.M. New York City time (or such other time as may be mutually agreed by the Borrower and such Swing Line Lender), request a quote of the Money Market Rate which would be applicable for such Swing Line Loans from a Swing Line Lender, specifying the amount of the proposed Money Market Rate Loans and the maturity date thereof. Such Swing Line Lender may, but shall not be obligated to, provide the Borrower with such Money Market Rate quote and such Swing Line Lender shall, not later than 12:30 P.M. New York City time on the day of the request, either (A) provide the Borrower with the requested quote or (B) notify the Borrower of its unwillingness

to provide the requested Swing Line Loans under the Money Market Rate; provided that the failure by such Swing Line Lender to provide such quote (or to notify the Borrower of such unwillingness) by such time shall be deemed as a notification of its unwillingness to provide the requested Swing Line Loans under the Money Market Rate. Upon receipt of such quote, the Borrower shall promptly (but not later than the time that an irrevocable notice requesting such Swing Line Loans must be made pursuant to this subsection 2.4(a)) notify the applicable Swing Line Lender whether it requests such Swing Line Lender to make Money Market Rate Loans at such Money Market Rate. If the Borrower does not request the Swing Line Loan at such Money Market Rate or no Swing Line Lender is willing to provide a Swing Line Loan at the Money Market Rate, the Borrower may still proceed to request a Swing Line Loan at the Base Rate or Eurodollar Rate as set forth in Section 2.3. The proceeds of each Swing Line Loan will be made available by the applicable Swing Line Lender to the Borrower not later than 3:00 P.M. New York City time on the Borrowing Date thereof by crediting the specified account of the Borrower with such proceeds in the manner from time to time agreed by the Borrower and the applicable Swing Line Lender; provided that prior to making the proceeds of such Swing Line Loan available to the Borrower, such Swing Line Lender receives a confirmation from the Administrative Agent that the amount of the requested Swing Line Loan is otherwise available to the Borrower under the Revolving Credit Commitments and the Swing Line Commitment. Immediately following the funding of such Swing Line Loan the applicable Swing Line Lender shall provide the Administrative Agent (which shall promptly forward a copy thereof to the Borrower and the other Swing Line Lenders) with a written confirmation of the amount, the Borrowing Date, whether such Swing Line Loan is a Eurodollar Loan, a Base Rate Loan or a Money Market Rate Loan and maturity of such Swing Line Loan.

(a)Each Swing Line Lender, at any time and from time to time in its sole and absolute discretion may, on behalf of the Borrower (which hereby irrevocably directs each Swing Line Lender to act on its behalf), on one Business Day's notice given by such Swing Line Lender to the Administrative Agent (which shall promptly forward such notice to each Revolving Credit Lender) no later than 12:00 Noon, New York City time, request each Revolving Credit Lender to make, and each Revolving Credit Lender hereby agrees to make, a Revolving Credit Loan (which shall initially be a Base Rate Loan), in an amount equal to such Revolving Credit Lender's Revolving Credit Percentage of the aggregate amount of any Swing Line Loans of such Swing Line Lender (the “Refunded Swing Line Loans”) outstanding on the date of such notice, to repay such Swing Line Lender. Each Revolving Credit Lender shall make the amount of such Revolving Credit Loan available to the Administrative Agent at the Funding Office in immediately available funds, not later than 10:00 A.M., New York City time, one Business Day after the date of such notice. The proceeds of such Revolving Credit Loans shall be made immediately available by the Administrative Agent to the applicable Swing Line Lender for application by such Swing Line Lender to the repayment of the Refunded Swing Line Loans.

(b)If prior to the time a Revolving Credit Loan would have otherwise been made pursuant to Section 2.4(b), one of the events described in Section 8(f) shall have occurred and be continuing with respect to the Borrower, or if for any other reason, as determined by the applicable Swing Line Lender in its sole discretion, Revolving Credit Loans may not be made as contemplated by Section 2.4(b), each Revolving Credit Lender shall, on the date such Revolving Credit Loan would have been made pursuant to the notice referred to in Section 2.4(b)(the “Refunding Date”), purchase for cash an undivided participating interest in the Refunded Swing Line Loans by paying to the applicable Swing Line Lender an amount (the “Swing Line Participation Amount”) equal to (i) such Revolving Credit Lender's Revolving Credit Percentage times (ii) the sum of the aggregate principal amount of the Refunded Swing Line Loans.

(c)Whenever, at any time after the applicable Swing Line Lender has received from any Revolving Credit Lender such Lender's Swing Line Participation Amount, such Swing Line Lender receives any payment on account of the applicable Swing Line Loans, such Swing Line Lender will distribute to the Administrative Agent for further distribution to such Lender its Swing Line Participation

Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender's participating interest was outstanding and funded and, in the case of principal and interest payments, to reflect such Lender's pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all such Swing Line Loans then due); provided, however, that in the event that such payment received by such Swing Line Lender is required to be returned, such Revolving Credit Lender will return to such Swing Line Lender any portion thereof previously distributed to it by the Administrative Agent on behalf of such Swing Line Lender.

(d)Each Revolving Credit Lender's obligation to make the Revolving Credit Loans referred to in Section 2.4(b) and to purchase participating interests pursuant to Section 2.4(c) shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any setoff, counterclaim, recoupment, defense or other right which such Revolving Credit Lender or the Borrower may have against the applicable Swing Line Lender, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 5; (iii) any adverse change in the condition (financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other Loan Document by the Borrower, or any other Revolving Credit Lender; or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.”

5.Repayment of Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of the appropriate Revolving Credit Lender the then unpaid principal amount of each Revolving Credit Loan of such Revolving Credit Lender on the Revolving Credit Termination Date (or on such earlier date on which the Loans become due and payable pursuant to Section 8) and (ii) to the applicable Swing Line Lender the then unpaid principal amount of each Swing Line Loan of such Swing Line Lender on the maturity date thereof (but in any event not later than the Revolving Credit Termination Date), or in each case on such earlier date on which the Loans become due and payable pursuant to Section 2.3(b) or 8. The Borrower hereby further agrees to pay interest on the unpaid principal amount of the Loans from time to time outstanding from the date hereof until payment in full thereof at the rates per annum, and on the dates, set forth in Section 2.11.

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

(b)The Administrative Agent, on behalf of the Borrower, shall maintain the Register pursuant to Section 10.6(d), and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Loan made hereunder and any Note evidencing such Loan, the Type of such Loan and each Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) both the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender's share thereof.

(c)The entries made in the Register and the accounts of each Lender maintained pursuant to Section 2.5(b) shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Loans made to the Borrower by such Lender in accordance with the terms of this Agreement.

(d)The Borrower agrees that, upon its receipt of notice of the request to the Administrative Agent by any Lender, the Borrower will promptly execute and deliver to such Lender a promissory note of the Borrower evidencing any Revolving Credit Loans or Swing Line Loans, as the case may be, of such Lender, substantially in the forms of Exhibit C-1 or C-2, respectively (a “Revolving Credit Note” or “Swing Line Note”, respectively), with appropriate insertions as to date and then outstanding principal amount; provided, that delivery of Notes shall not be a condition precedent to the

occurrence of the Closing Date or the making of the Loans or issuance of Letters of Credit on the Closing Date.

6.Commitment Fees, etc. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Revolving Credit Lender a commitment fee for the period from and including the Closing Date to the last day of the Revolving Credit Commitment Period, computed at the Commitment Fee Rate on the average daily amount of the Available Revolving Credit Commitment of such Lender during the period for which payment is made, payable quarterly in arrears on the last day of each March, June, September and December and on the Revolving Credit Termination Date, commencing on the first of such dates to occur after the date hereof; provided, however, that no Commitment Fee shall accrue on any of the Revolving Credit Commitment of a Defaulting Lender so long as such Lender shall be a Defaulting Lender. For purposes of clarification, Swing Line loans shall be considered outstanding for the purpose of determining the unused portion of the Revolving Credit Commitment.

(a)The Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates agreed to in the Fee Letters (or otherwise from time to time agreed to in writing by the Borrower and the Administrative Agent).

7.Termination or Reduction of Revolving Credit Commitments. The Borrower shall have the right, upon not less than three Business Days' notice to the Administrative Agent, without premium or penalty, to terminate the Revolving Credit Commitments or, from time to time, to reduce the aggregate amount of the Revolving Credit Commitments; provided that no such termination or reduction of Revolving Credit Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Revolving Credit Loans and Swing Line Loans made on the effective date thereof, the Total Revolving Extensions of Credit would exceed the Total Revolving Credit Commitments. Any such reduction shall be in an amount equal to $1,000,000, or a whole multiple thereof, and shall reduce permanently the Revolving Credit Commitments then in effect.

8.Optional Prepayments. The Borrower may at any time and from time to time prepay the Loans, in whole or in part, without premium or penalty (but including breakage costs, if any, pursuant to Section 2.17), upon irrevocable notice delivered to the Administrative Agent no later than 11:00 A.M., New York City time, three Business Days prior thereto in the case of Eurodollar Loans and no later than 11:00 A.M., New York City time, one Business Day prior thereto in the case of Base Rate Loans, which notice shall specify the date and amount of such prepayment and whether such prepayment is of Eurodollar Loans or Base Rate Loans; provided, that (i) if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.17 and (ii) no prior notice is required for the prepayment of Swing Line Loans. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Revolving Credit Loans that are Base Rate Loans) accrued interest to such date on the amount prepaid. Partial prepayments of Revolving Credit Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple thereof. Partial prepayments of Swing Line Loans shall be in an aggregate principal amount of $100,000 or a whole multiple thereof.

9.Conversion and Continuation Options. (a) The Borrower may elect from time to time to convert Eurodollar Loans (other than Swing Line Loans) to Base Rate Loans by giving the Administrative Agent at least one Business Day prior irrevocable notice of such election; provided that any such conversion of Eurodollar Loans may be made only on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert Base Rate Loans (other than Swing Line Loans) to Eurodollar Loans by giving the Administrative Agent irrevocable notice of such election no later than 12:00 noon, New York City time, three Business Days prior thereto (which notice shall specify the length of the initial Interest Period therefor); provided that no Base Rate Loan may be converted into a Eurodollar Loan (i) when any Event of Default has occurred and is continuing and the

Administrative Agent has, or the Required Lenders have, determined in its or their sole discretion not to permit such conversions or (ii) after the date that is two weeks prior to the final scheduled termination or maturity date of the Facility. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof.

(a)The Borrower may elect to continue any Eurodollar Loan (other than a Swing Line Loan which shall automatically convert into a Base Rate Loan upon its maturity pursuant to Section 2.11(c)) as such upon the expiration of the then current Interest Period with respect thereto by giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loan; provided that no Eurodollar Loan under the Facility may be continued as such (i) when any Event of Default has occurred and is continuing and the Administrative Agent has, or the Required Lenders have, determined in its or their sole discretion not to permit such continuations or (ii) after the date that is two weeks prior to the final scheduled termination or maturity date of the Facility; and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso, such Loans shall be converted automatically to Base Rate Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

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

11.Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate applicable to such Eurodollar Loan plus the Applicable Margin with respect to Eurodollar Loans in effect for such day.

(a)Each Base Rate Loan shall bear interest for each day on which it is outstanding at a rate per annum equal to the Base Rate in effect for such day plus the Applicable Margin with respect to Base Rate Loans in effect for such day.

(b)Each Swing Line Loan which is a Money Market Loan or a Eurodollar Loan shall bear interest for each day on which it is outstanding prior to maturity thereof at a rate per annum equal to the applicable Money Market Rate or the rate then applicable to such Eurodollar Loan (including the Applicable Margin) and thereafter, at a rate per annum equal to the rate then applicable to Base Rate Loans (including the Applicable Margin) pursuant to this Section.

(c)(i) If all or a portion of the principal amount of any Loan or Reimbursement Obligation shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), all outstanding Loans and Reimbursement Obligations (whether or not overdue)(to the extent legally permitted) shall bear interest at a rate per annum that is equal to (x) in the case of the Loans, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% or (y) in the case of Reimbursement Obligations, the rate applicable to Base Rate Loans (including the Applicable Margin) plus 2%, and (ii) if all or a portion of any interest payable on any Loan or Reimbursement Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to Base Rate Loans (including the Applicable Margin) plus 2%, in each case, with respect to clauses (i) and (ii) above, from the date of such non‑payment until such amount is paid in full (after as well as before judgment). If one of the events described in Section 8(f) shall have occurred and be continuing with respect to the Borrower, or if, after

giving a notice referred to in Section 2.4(b), for any other reason, as determined by the applicable Swing Line Lender in its sole discretion, Revolving Credit Loans may not be made as contemplated by Section 2.4(b), each Swing Line Loan shall bear interest until paid in full at a rate per annum equal to the rate then applicable to Base Rate Loans (including the Applicable Margin) plus 2%.

(d)Interest shall be payable in arrears on each Interest Payment Date; provided that interest accruing pursuant to paragraph (d) of this Section shall be payable from time to time on demand.

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

(a)Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.11(a).

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

(a)the Administrative Agent shall have reasonably determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

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

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then current Interest Period with respect thereto, to Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Loans to Eurodollar Loans.

14.Pro Rata Treatment and Payments. (a) Each borrowing (other than borrowings of Swing Line Loans) by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee or Letter of Credit Fee, and any reduction of the Commitments of the Lenders, shall be made pro rata according to the Revolving Credit Percentages of the Lenders. Each payment of interest in respect of the Loans and each payment in respect of fees payable hereunder shall be applied to the amounts of such obligations owing to the applicable Lenders pro rata according to the respective amounts then due and owing to such Lenders.

(a)Each payment (including each prepayment) by the Borrower on account of principal of the Revolving Credit Loans shall be made pro rata according to the respective outstanding

principal amounts of the Revolving Credit Loans then held by the Revolving Credit Lenders. Each payment in respect of Reimbursement Obligations in respect of any Letter of Credit shall be made to the Issuing Lender that issued such Letter of Credit. Each payment by the Borrower on account of principal of or interest on Swing Line Loans shall be made to the applicable Swing Line Lender (to be applied, if applicable, as provided in Section 2.4(d)).

(b)The application of any payment of Loans under the Facility (including optional and mandatory prepayments) shall be made, first, to Base Rate Loans under the Facility and, second, to Eurodollar Loans under the Facility. Each payment of the Loans (except in the case of Revolving Credit Loans that are Base Rate Loans) shall be accompanied by accrued interest to the date of such payment on the amount paid.

(c)All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the relevant Lenders, at the Payment Office, in Dollars and in immediately available funds (or, in the case of all payments by the Borrower of principal of or interest on Swing Line Loans, to the applicable Swing Line Lender for its account at such payment office as agreed between the Borrower and such Swing Line Lender, in Dollars and in immediately available funds). Any payment made by the Borrower after 12:00 Noon, New York City time, on any Business Day shall be deemed to have been on the next following Business Day. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

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

(e)Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence,

such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

(f)Subject to Section 2.21(a)(ii), upon receipt by the Administrative Agent of payments on behalf of Lenders, the Administrative Agent shall promptly distribute such payments to the Lender or Lenders entitled thereto, in like funds as received by the Administrative Agent.

15.Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i)shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.16 and changes in the rate of tax on the overall net income of such Lender);

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

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

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled. For purposes of this clause (a) and clause (b) below, (x) the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a change in Requirement of Law regardless of the date enacted, adopted or issued.

(a)If any Lender shall have reasonably determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction; provided that the Borrower shall not be required to

compensate a Lender pursuant to this paragraph for any amounts incurred more than six months prior to the date that such Lender notifies the Borrower of such Lender's intention to claim compensation therefor; and provided, further, that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect.

(b)A certificate as to any additional amounts payable pursuant to this Section (and setting forth calculations in reasonable detail demonstrating the basis therefor) submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

16.Taxes. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on any Agent or any Lender as a result of a present or former connection between such Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from such Agent's or such Lender's having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or any Other Taxes are required to be withheld from any amounts payable to any Agent or any Lender hereunder, the amounts so payable to such Agent or such Lender shall be increased to the extent necessary to yield to such Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement; provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender's failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender immediately prior to the time such Lender becomes a party to this Agreement, except to the extent that such Lender's assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph (a).

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

(b)Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for the account of the relevant Agent or Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agents and the Lenders for any incremental taxes, interest or penalties that may become payable by any Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

(c)Each Lender (or Transferee) that is not a “U.S. Person” as defined in Section 7701(a)(30) of the Code (a “Non‑U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two duly completed copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non‑U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest” a duly completed

statement substantially in the form of Exhibit E and a Form W-8BEN, or any subsequent versions thereof or successors thereto properly completed and duly executed by such Non‑U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non‑U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non‑U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non‑U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non‑U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non‑U.S. Lender is not legally able to deliver.

(d)A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate; provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender's reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

17.Indemnity. The Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment or conversion of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period or maturity date applicable thereto as a result of a request by the Borrower pursuant to Section 2.20. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank Eurodollar market. A certificate as to any amounts payable pursuant to this Section (and setting forth calculations in reasonable detail demonstrating the basis therefor) submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

18.Illegality. Notwithstanding any other provision herein, if after the Closing Date the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be suspended until such condition shall cease to exist and (b) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest

Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.17.

19.Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.15, 2.16(a) or 2.18 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage; and provided, further, that nothing in this Section shall affect or postpone any of the obligations of the Borrower or the rights of any Lender pursuant to Section 2.15, 2.16(a) or 2.18.

20.Replacement of Lenders under Certain Circumstances. The Borrower shall be permitted to replace with a replacement financial institution any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.15 or 2.16 or gives a notice of illegality pursuant to Section 2.18, (b) defaults in its obligation to make Loans hereunder (or is otherwise a Defaulting Lender) or (c) refuses to consent to any amendment, waiver or other modification of any Loan Document requested by the Borrower that requires the consent of all Lenders and such amendment, waiver or other modification is consented to by the Required Lenders; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement, such Lender shall have taken no action under Section 2.19 so as to eliminate the continued need for payment of amounts owing pursuant to Section 2.15 or 2.16 or to eliminate the illegality referred to in such notice of illegality given pursuant to Section 2.18, (iv) the replacement financial institution shall purchase, at par, all Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 2.17 (as though Section 2.17 were applicable) if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 10.6 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein), (viii) the Borrower shall pay all additional amounts (if any) required pursuant to Section 2.15 or 2.16, as the case may be, in respect of any period prior to the date on which such replacement shall be consummated, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

21.Defaulting Lenders.

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

(i)Waivers and Amendments. That Defaulting Lender's right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.01.

(ii)Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise, and including any amounts made available to the Administrative Agent by that Defaulting Lender pursuant to Section 10.07), shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder; second, to the

payment on a pro rata basis of any amounts owing by that Defaulting Lender to the Issuing Lender or Swing Line Lender hereunder; third, if so determined by the Administrative Agent or requested by the Issuing Lender or Swing Line Lender, to be held as Cash Collateral for future funding obligations of that Defaulting Lender of any participation in any Swing Line Loan or Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Agreement; sixth, to the payment of any amounts owing to the Lenders, the Issuing Lender or Swing Line Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Lender or Swing Line Lender against that Defaulting Lender as a result of that Defaulting Lender's breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender's breach of its obligations under this Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Obligations in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Loans or L/C Obligations were made at a time when the conditions set forth in Section 5.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Obligations owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Obligations owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.21(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto.

(iii)Certain Fees. That Defaulting Lender (x) shall not be entitled to receive any commitment fee pursuant to Section 2.6 for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender) and (y) shall be limited in its right to receive Letter of Credit Fees as provided in Section 3.3. If the Borrower Cash Collateralizes any portion of a Defaulting Lender's L/C Obligations pursuant to Section 2.22(a), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.3 with respect to such Defaulting Lender's L/C Obligations during the period such Defaulting Lender's L/C Obligations are Cash Collateralized.

(iv)Reallocation of Applicable Percentages to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit or Swing Line Loans pursuant to Sections 2.04 and 2.05, the “Applicable Percentage” of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit and Swing Line Loans shall not exceed the positive difference, if any, of (1) the

Commitment of that non-Defaulting Lender minus (2) the aggregate Outstanding Amount of the Revolving Credit Loans of that Lender.

(b)Defaulting Lender Cure. If the Borrower, the Administrative Agent, Swing Line Lender and the Issuing Lender agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Revolving Credit Loans and funded and unfunded participations in Letters of Credit and Swing Line Loans to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 2.21(a)(iv)), whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender.

2.22 Cash Collateral.

(a) Certain Credit Support Events. Upon the request of the Administrative Agent or the Issuing Lender if, as of the Letter of Credit Expiration Date, any L/C Obligation for any reason remains outstanding, the Borrower shall immediately Cash Collateralize the then outstanding amount of all L/C Obligations. At any time that there shall exist a Defaulting Lender, immediately upon the request of the Administrative Agent, the L/C Issuer or the Swing Line Lender, the Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.21(a)(iv) and any Cash Collateral provided by the Defaulting Lender).

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts at Bank of America. The Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the L/C Issuer and the Lenders (including the Swing Line Lender), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.22(c). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, the Borrower or the relevant Defaulting Lender will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(c) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided in respect of Letters of Credit or Swing Line Loans shall be held and applied to the satisfaction of the specific L/C Obligations, Swing Line Loans, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable

Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 10.06(d)) or (ii) the Administrative Agent's good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of the Borrower shall not be released during the continuance of a Default or Event of Default (and following application as provided in this Section 2.22 may be otherwise applied in accordance with Article 8), and (y) the Person providing Cash Collateral and the L/C Issuer or Swing Line Lender, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.


SECTION 3.	LETTERS OF CREDIT

1.L/C Commitment. (a) Subject to the terms and conditions hereof, each Issuing Lender, in reliance on the agreements of the other Revolving Credit Lenders set forth in Section 3.4, agrees to issue sight letters of credit on a standby basis (the “Letters of Credit”) in support of the L/C Supportable Obligations for the account of the Borrower on any Business Day during the Revolving Credit Commitment Period in such form as may be approved from time to time by such Issuing Lender; provided, that no Issuing Lender shall have any obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the aggregate amount of the Available Revolving Credit Commitments would be less than zero. Notwithstanding the foregoing, no Issuing Lender shall have any obligation to issue any Letter of Credit on any date that is later than seven Business Days prior to the Revolving Credit Termination Date. Each Letter of Credit shall (i) be denominated in Dollars and (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date which is five Business Days prior to the Revolving Credit Termination Date; provided that any Letter of Credit may provide for the extension thereof for up to additional one year periods (which shall in no event extend beyond the date referred to in clause (y) above).

(a)No Issuing Lender shall at any time be obligated to issue any Letter of Credit hereunder if (i) there shall have occurred and be continuing a Default or Event of Default shall exist or (ii) such issuance would conflict with, or cause such Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law.

(b)So long as any Lender is a Defaulting Lender, no Issuing Lender shall be required to issue, amend or increase any Letters of Credit, unless it is satisfied that the related exposure and such Defaulting Lender's then outstanding L/C Obligations will be 100% covered by the Commitments of the non-Defaulting Lenders (by re-allocation among non-Defaulting Lenders (without the participation of such Defaulting Lender therein) as provided in Section 2.21(a)(iv)) and/or by Cash Collateral provided by such Defaulting Lender (and/or by the Borrower in accordance with Section 2.22(a)).

2.Procedure for Issuance of Letter of Credit. The Borrower may from time to time request that an Issuing Lender issue a Letter of Credit by delivering to such Issuing Lender (with a copy to the Administrative Agent) a Letter of Credit Request in the form of Exhibit G, attached hereto, accompanied by such other certificates, documents and other papers and other information as such Issuing Lender may request. If the Issuing Lender shall so reasonably request, each Letter of Credit Request shall be accompanied by an Application; provided that if the Administrative Agent reasonably determines that such Application contains all information required with respect to a Letter of Credit, no Letter of Credit Request shall be necessary. Upon receipt of any Letter of Credit Request, an Issuing Lender will process such request in accordance with its customary procedures. The Issuing Lender, upon determining that it has received an acceptable Letter of Credit Request, that the terms and conditions of the requested Letter of Credit are acceptable to it and that the Administrative Agent has confirmed that such issuance would not cause (i) the L/C Obligations to exceed the L/C Commitment or (ii) the aggregate amount of the Available Revolving Credit Commitments to be less than zero, shall issue the Letter of Credit (but in no event shall any Issuing Lender be required to issue any Letter of Credit earlier than three Business Days after its receipt of a Letter of Credit Request). The original of any Letter of Credit shall be delivered to

the beneficiary thereof or as otherwise agreed to by the Borrower and the Issuing Lender. Promptly after the issuance or amendment of a Letter of Credit, the Issuing Lender shall promptly notify the Administrative Agent and the Borrower, in writing, of such issuance or amendment and such notice shall be accompanied by a copy of such issuance or amendment. Upon receipt of such notice, the Administrative Agent shall notify each L/C Participant of such issuance or amendment, and if so requested by an L/C Participant, the Administrative Agent shall provide such L/C Participant with copies of such issuance or amendment.

3.Fees and Other Charges. (a) The Borrower will pay a fee to the Administrative Agent, for the ratable benefit of the Revolving Credit Lenders, on the daily aggregate drawable amount of all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans under the Revolving Credit Facility ( the “Letter of Credit Fee”), shared ratably among the Revolving Credit Lenders in accordance with their respective Revolving Credit Percentages and payable quarterly in arrears on each L/C Fee Payment Date after the issuance date; provided, however, any fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the Issuing Lender pursuant to Section 3.1(c) shall be payable, to the maximum extent permitted by applicable Law, to the other Lenders in accordance with the upward adjustments in their respective Applicable Percentages allocable to such Letter of Credit pursuant to Section 2.21(a)(iv), with the balance of such fee, if any, payable to the Borrower to the extent that the Borrower has provided Cash Collateral on account of such Defaulting Lender pursuant to Section 2.22(a) and otherwise to the Issuing Lender for its own account; provided further that any fee payable to a Defaulting Lender shall be subject to Section 2.21(a)(iii). In addition, except as otherwise agreed to between the relevant Issuing Lender and the Borrower, the Borrower shall pay to the relevant Issuing Lender for its own account a fronting fee on the aggregate drawable amount of all outstanding Letters of Credit issued by it of 0.125% per annum, payable quarterly in arrears on each L/C Fee Payment Date after the issuance date. Notwithstanding anything to the contrary contained herein, while any of the events described in Section 8(f) shall have occurred and be continuing with respect to the Borrower, the Letter of Credit Fee shall accrue at a rate equal to the Applicable Margin plus 2% per annum.

(a)In addition to the foregoing fees, the Borrower shall pay or reimburse each Issuing Lender quarterly in arrears on each L/C Fee Payment Date for such reasonable, normal and customary costs and expenses as are incurred or charged by such Issuing Lender in issuing, effecting payment under, amending or otherwise administering any Letter of Credit.

4.L/C Participations. (a) Each Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce each Issuing Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from each Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant's own account and risk, an undivided interest equal to such L/C Participant's Revolving Credit Percentage of each Issuing Lender's obligations and rights under each Letter of Credit issued by such Issuing Lender hereunder and the amount of each draft paid by such Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with each Issuing Lender that, if a draft is paid under any Letter of Credit issued by such Issuing Lender for which such Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such L/C Participant shall pay to the Administrative Agent for the account of such Issuing Lender upon demand at the Funding Office (and thereafter the Administrative Agent shall promptly pay to such Issuing Lender) an amount equal to such L/C Participant's Revolving Credit Percentage of the amount of such draft, or any part thereof, that is not so reimbursed. Each L/C Participant's obligation to pay such amount shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such L/C Participant may have against the Issuing Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of a Default or an Event of Default

or the failure to satisfy any of the other conditions specified in Section 5, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower or any other L/C Participant or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. The failure of any L/C Participant to make any payment pursuant to this Section 3.4 shall not relieve any other L/C Participant of its obligation hereunder.

(a)If any amount (a “Participation Amount”) required to be paid by any L/C Participant to an Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit is paid to such Issuing Lender within three Business Days after the date such payment is due, such Issuing Lender shall so notify the Administrative Agent, which shall promptly notify the L/C Participants, and each L/C Participant shall pay to the Administrative Agent, for the account of such Issuing Lender, on demand (and thereafter the Administrative Agent shall promptly pay to such Issuing Lender) an amount equal to the product of (i) such Participation Amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such payment is required to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any Participation Amount required to be paid by any L/C Participant pursuant to Section 3.4(a) is not made available to the Administrative Agent for the account of the relevant Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, the Administrative Agent on behalf of such Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such Participation Amount with interest thereon calculated from such due date at the rate per annum applicable to Base Rate Loans under the Revolving Credit Facility. A certificate of the Administrative Agent submitted on behalf of an Issuing Lender to any L/C Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error.

(b)Whenever, at any time after an Issuing Lender has made payment under any Letter of Credit and has received from the Administrative Agent any L/C Participant's pro rata share of such payment in accordance with Section 3.4(a), such Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by such Issuing Lender), or any payment of interest on account thereof, such Issuing Lender will distribute to the Administrative Agent for the account of such L/C Participant (and thereafter the Administrative Agent will promptly distribute to such L/C Participant) its pro rata share thereof; provided, however, that in the event that any such payment received by such Issuing Lender shall be required to be returned by such Issuing Lender, such L/C Participant shall return to the Administrative Agent for the account of such Issuing Lender (and thereafter the Administrative Agent shall promptly return to such Issuing Lender) the portion thereof previously distributed by such Issuing Lender.

5.Reimbursement Obligation of the Borrower. The Borrower agrees to reimburse each Issuing Lender, within one Business Day (or two Business Days if the Borrower and the Administrative Agent are notified on after 11:00 a.m. New York City time on such date) after the Business Day on which such Issuing Lender notifies the Borrower and the Administrative Agent of the date and amount of a draft presented under any Letter of Credit and paid by such Issuing Lender, for the amount of (a) such draft so paid and (b) any taxes, fees, charges or other costs or expenses incurred by such Issuing Lender in connection with such payment (the amounts described in the foregoing clauses (a) and (b) in respect of any drawing, collectively, the “Payment Amount”). Each such payment shall be made to such Issuing Lender at its address for notices specified herein in lawful money of the United States of America and in immediately available funds. Interest shall be payable on each Payment Amount from the date of the applicable drawing until payment in full at the rate set forth in (i) until the second Business Day following the date of the applicable drawing, Section 2.11(b) and (ii) thereafter, Section 2.11(c). Each notice from an Issuing Lender of a drawing under any Letter of Credit shall (unless an event of the type

described in clause (i) or (ii) of Section 8(f) shall have occurred and be continuing with respect to the Borrower, in which case the procedures specified in Section 3.4 for funding by L/C Participants shall apply) constitute a request by the Borrower to the Administrative Agent for a borrowing pursuant to Section 2.2 of Base Rate Loans (or, at the option of the Administrative Agent and the applicable Swing Line Lender in their sole discretion, a borrowing pursuant to Section 2.4 of Swing Line Loans) in the amount of such drawing. The Borrowing Date with respect to such borrowing shall be the first date on which a borrowing of Revolving Credit Loans (or, if applicable, Swing Line Loans) could be made, pursuant to Section 2.2 (or, if applicable, Section 2.4), if the Administrative Agent had received a notice of such borrowing at the time the Administrative Agent receives notice from the relevant Issuing Lender of such drawing under such Letter of Credit.

6.Obligations Absolute. The Borrower's obligations under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against any Issuing Lender, any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees with each Issuing Lender that such Issuing Lender shall not be responsible for, and the Borrower's Reimbursement Obligations under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. No Issuing Lender shall be liable to the Borrower for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Issuing Lender. The Borrower, the Lenders and any other party hereto agree that any action taken or omitted by an Issuing Lender under or in connection with any Letter of Credit issued by it or the related drafts or documents, including without limitation the payment thereof, absent a finding of gross negligence or willful misconduct of the Issuing Lender as determined by a final and nonappealable decision of a court of competent jurisdiction, shall be binding on the Borrower, the Lenders and any other party hereto and shall not result in any liability of such Issuing Lender to the Borrower, the Lenders or any other party hereto.

7.Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the relevant Issuing Lender shall promptly notify the Borrower and the Administrative Agent of the date and amount thereof. The responsibility of the relevant Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit, in addition to any payment obligation expressly provided for in such Letter of Credit issued by such Issuing Lender, shall be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment appear on their face to be in conformity with such Letter of Credit.

8.Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply.

9.Existing Letters of Credit. The Borrower, the Administrative Agent, the Revolving Credit Lenders and the Issuing Bank hereby acknowledge that on and as of the Closing Date the Existing Letters of Credit shall irrevocably be deemed to be Letters of Credit under this Agreement and all the provisions of this Agreement shall apply to the Existing Letters of Credit as being Letters of Credit issued under this Agreement by the relevant Issuing Bank, the whole without novation of all of the obligations of Borrower to each relevant Issuing Bank in respect of said Existing Letters of Credit.

SECTION 4. REPRESENTATIONS AND WARRANTIES

To induce the Agents and the Lenders to enter into this Agreement and to make the Loans and issue or participate in the Letters of Credit, the Borrower hereby represents and warrants to each Agent

SECTION 9.	THE AGENTS

1.Appointment. Each Lender hereby irrevocably designates and appoints the Agents (for the purposes of this Section 9 the term “Agents” shall also include any Issuing Lender acting in its capacity as such) as the agents of such Lender under this Agreement and the other Loan Documents, and each Lender irrevocably authorizes each Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to such Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, no Agent shall have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against any Agent.

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

3.Exculpatory Provisions. Neither any Agent nor any of its officers, directors, employees, agents, attorneys‑in‑fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person's own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this Agreement or

any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower.

4.Reliance by Agents. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower), independent accountants and other experts selected by such Agent. The Agents may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 10.6 and all actions required by such Section in connection with such transfer shall have been taken. Each Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

5.Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless such Agent shall have received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent shall receive such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

6.Non‑Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that neither any of the Agents nor any of their respective officers, directors, employees, agents, attorneys‑in‑fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of the Borrower or any affiliate of the Borrower, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and its affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation

as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower and its affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or any affiliate of the Borrower that may come into the possession of such Agent or any of its officers, directors, employees, agents, attorneys‑in‑fact or affiliates.

7.Indemnification. The Lenders agree to indemnify each Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), for, and to save each Agent harmless from and against, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including, without limitation, at any time following the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent's gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

8.Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower or any of its Subsidiaries as though such Agent were not an Agent. With respect to its Loans made or renewed by it and with respect to any Letter of Credit issued or participated in by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent in its individual capacity.

9.Successor Agents. The Administrative Agent may resign as Administrative Agent upon 10 days' notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent's rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 10 days following a retiring Administrative Agent's notice of resignation, the retiring Administrative Agent's resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

(a)The Syndication Agent may, at any time, by notice to the Lenders and the Administrative Agent, resign as Syndication Agent hereunder, whereupon the duties, rights, obligations

and responsibilities of the Syndication Agent hereunder shall automatically be assumed by, and inure to the benefit of, the Administrative Agent, without any further act by the Syndication Agent, the Administrative Agent or any Lender.

(b)After any retiring Agent's resignation as Agent, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents.

10.The Joint Lead Arrangers; the Syndication Agent; the Co-Documentation Agents. Neither the Joint Lead Arrangers, the Syndication Agent nor the Co-Documentation Agents, in their respective capacities as such, shall have any duties or responsibilities, and shall incur no liability, under this Agreement and the other Loan Documents.

SECTION 10. MISCELLANEOUS

1.Amendments and Waivers. Neither this Agreement or any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.1. The Required Lenders and the Borrower may, or (with the written consent of the Required Lenders) the Administrative Agent and the Borrower may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents (including amendments and restatements hereof or thereof) for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Borrower hereunder or thereunder or (b) waive, on such terms and conditions as may be specified in the instrument of waiver, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall, without the consent of the requisite Lenders specified below:

(i)forgive the principal amount or extend the final scheduled date of maturity of any Loan or Reimbursement Obligation, reduce the stated rate of any interest or fee payable under this Agreement (except (x) in connection with the waiver of applicability of any post-default increase in interest rates (which waiver shall be effective with the consent of the Required Lenders and (y) that any amendment or modification of defined terms used in the financial covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (i)) or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Commitment of any Lender, in each case without the consent of each Lender directly affected thereby;

(ii)amend, modify or waive any provision of this Section or reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan Documents, in each case without the consent of all the Lenders;

(iii)amend, modify or waive any condition precedent to any extension of credit under the Revolving Credit Facility set forth in Section 5.2 (including, without limitation, the waiver of an existing Default or Event of Default required to be waived in order for such extension of credit to be made) without the consent of the Required Lenders;

(iv)reduce the percentage specified in the definition of Required Lenders without the consent of all of the Lenders;

(v)amend, modify or waive any provision of Section 9, or any other provision affecting the rights, duties or obligations of any Agent, without the consent of any Agent directly affected thereby;

(vii)amend, modify or waive any provision of Section 2.14 or 10.7 without the

consent of each Lender directly affected thereby;

(viii)amend, modify or waive any provision of Section 3 (or Annex B) without the consent of each Issuing Lender affected thereby;

(ix)impose restrictions on assignments and participations that are more restrictive than, or additional to, those set forth in Section 10.6 without the consent of all the Lenders; or

(x)except as provided in Section 2.21, change any provision hereof in a manner that would alter the pro rata sharing of payments required by Section 2.14, without the written consent of each Lender whose pro rata share could otherwise be reduced thereby.

Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Borrower, the Lenders, the Agents and all future holders of the Loans. In the case of any waiver, the Borrower, the Lenders and the Agents shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. Any such waiver, amendment, supplement or modification shall be effected by a written instrument signed by the parties required to sign pursuant to the foregoing provisions of this Section; provided, that delivery of an executed signature page of any such instrument by facsimile or email transmission shall be effective as delivery of a manually executed counterpart thereof.

For the avoidance of doubt, this Agreement and any other Loan Document may be amended (or amended and restated) with the written consent of the Required Lenders, the Administrative Agent and the Borrower (x) to add one or more additional credit facilities to this Agreement and to permit the extensions of credit from time to time outstanding thereunder and the accrued interest and fees in respect thereof (collectively, the “Additional Extensions of Credit”) to share ratably in the benefits of this Agreement and the other Loan Documents with the Revolving Extensions of Credit and the accrued interest and fees in respect thereof and (y) to include appropriately the Lenders holding such credit facilities in any determination of the Required Lenders.

For the avoidance of doubt, an increase in the Revolving Credit Commitments pursuant to Section 2.1(b) shall not be deemed an amendment, modification or supplement to this Agreement.

Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting Lenders), except that (x) the Commitment of any Defaulting Lender may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender.

court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee. No Indemnitee shall be liable for any damages arising from the use by unauthorized persons of information, data, reports or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons (unless it is finally judicially determined that such interception was directly a result of the gross negligence or willful misconduct of such Indemnitee) or for any special, indirect, consequential or punitive damages in connection with the Facilities. Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries so to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section shall be payable not later than 30 days after written demand therefor. Statements payable by the Borrower pursuant to this Section shall be submitted to ▇▇▇▇▇ ▇▇▇▇ (Telephone No.(▇▇▇) ▇▇▇-▇▇▇▇)(Fax No. (▇▇▇) ▇▇▇-▇▇▇▇), at the address of the Borrower set forth in Section 10.3, or to such other Person or address as may be hereafter designated by the Borrower in a notice to the Administrative Agent. The agreements in this Section shall survive repayment of the Loans and all other amounts payable hereunder.

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

(a)Any Lender may, in the ordinary course of its business, without the consent of the Borrower, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a “Participant”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan for all purposes under this Agreement and the other Loan Documents, and the Borrower and the Agents shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would require the consent of all Lenders pursuant to Section 10.1. The Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement; provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as if such Participant were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 with respect to its participation in the Commitments and the Loans outstanding from time to time as if such Participant were a Lender; provided that, in the case of Section 2.16, such Participant shall have complied with the requirements of said Section; and provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer

occurred.

(b)Any Lender (an “Assignor”) may, in the ordinary course of its business, in accordance with applicable law and upon written notice to the Administrative Agent, at any time and from time to time assign to any Lender or any affiliate, Related Fund or, with the consent of the Borrower and the Administrative Agent and, in the case of any assignment of Revolving Credit Commitments, the written consent of the Issuing Lender and the Swing Line Lenders (which, in each case, shall not be unreasonably withheld or delayed)(provided that no consent from the applicable parties need be obtained by any Bank of America Entity in its capacity as Assignor (other than, solely in the case of any assignment of Revolving Credit Commitments, the consent of the Issuing Lender and the Swing Line Lenders (which, in each case, shall not be unreasonably withheld or delayed)), to an additional bank, financial institution or other entity (an “Assignee”) all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance, substantially in the form of Exhibit D, executed by such Assignee and such Assignor (and, where the consent of the Borrower, the Administrative Agent, the Issuing Lender or the Swing Line Lenders is required pursuant to the foregoing provisions, by the Borrower and such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that with respect to assignments of Revolving Credit Commitments, no such assignment to an Assignee (other than any Lender or any Affiliate or Related Fund thereof) shall be in an aggregate principal amount of less than $5,000,000 (other than in the case of an assignment of all of a Lender's interests under this Agreement) and, after giving effect thereto, such Assignor shall have Revolving Credit Commitments and Revolving Credit Loans aggregating at least $5,000,000 (if holding any), unless otherwise agreed by the Borrower and the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with Commitments and/or Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor's rights and obligations under this Agreement, such Assignor shall cease to be a party hereto, except as to Section 2.15, 2.16 and 10.5 in respect of the period prior to such effective date). Notwithstanding any provision of this Section, the consent of the Borrower shall not be required for any assignment that occurs at any time when any Event of Default shall have occurred and be continuing. For purposes of the minimum assignment amounts and minimum hold amounts set forth in this paragraph, multiple assignments to or by two or more Related Funds shall be aggregated.

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

(d)The Administrative Agent shall, on behalf of the Borrower, maintain at its address

referred to in Section 10.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, each Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Loans and any Notes evidencing such Loans recorded therein for all purposes of this Agreement. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Notes shall be returned by the Administrative Agent to the Borrower marked “canceled”. The Register shall be available for inspection by the Borrower or any Lender (with respect to any entry relating to such Lender's Loans) at any reasonable time and from time to time upon reasonable prior notice.

(e)Upon its receipt of an Assignment and Acceptance executed by an Assignor and an Assignee (and, in any case where the consent of any other Person is required by Section 10.6(c), by each such other Person) together with payment by the applicable Assignor or Assignee to the Administrative Agent of a registration and processing fee of $3,500 (treating multiple, simultaneous assignments by or to two or more Related Funds as a single assignment) (except that no such registration and processing fee shall be payable (y) in connection with an assignment by or to a Bank of America Entity or (z) in the case of an Assignee which is already a Lender or is an affiliate or Related Fund of a Lender or a Person under common management with a Lender), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Borrower. The Borrower, at its own expense, promptly upon receipt of a request by the Administrative Agent, shall execute and deliver to the Administrative Agent (in exchange for the Revolving Credit Note of the assigning Lender) a new Revolving Credit Note to the order of such Assignee in an amount equal to the Revolving Credit Commitment assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Revolving Credit Commitment, upon request, a new Revolving Credit Note to the order of the Assignor in an amount equal to the Revolving Credit Commitment retained by it hereunder. Such new Note or Notes shall be dated the effective date of the relevant assignment and shall otherwise be in the form of the Note or Notes replaced thereby.

(f)For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests in Loans and Notes, including, without limitation, any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank in accordance with applicable law.

(g)Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender 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 Lender 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 Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender).

In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other 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 in this Section 10.6(g), any SPC may (A) 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 Lender, or with the prior written consent of the Borrower and the Administrative Agent (which consent shall not be unreasonably withheld) to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans, and (B) 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; provided that non-public information with respect to the Borrower may be disclosed only with the Borrower's consent which will not be unreasonably withheld. This paragraph (f) may not be amended without the written consent of any SPC with Loans outstanding at the time of such proposed amendment.

7.Adjustments; Set‑off. (a) Except to the extent that this Agreement provides for payments to be allocated to a particular Lender or to the Lenders under a particular Facility, if any Lender (a “Benefitted Lender”) shall at any time receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set‑off, pursuant to events or proceedings of the nature referred to in Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender's Obligations, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender's Obligations, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(a)Upon the occurrence and during the continuance of an Event of Default, in addition to any rights and remedies of the Lenders provided by law, each Lender, including without limitation each Issuing Lender, shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such setoff and application; provided, further, that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.22 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff.

8.Counterparts. This Agreement may be executed by one or more of the parties to

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

9.Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

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

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

(e)waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

13.Acknowledgments. The Borrower hereby acknowledges that:

(b)no Joint Lead Arranger, Agent nor any Lender has any fiduciary relationship with or duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Joint Lead Arrangers, the Agents and the Lenders, on one hand, and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

1.The borrower is subject to Section 204 of the Federal Power Act. The Borrower applied to the Federal Energy Regulatory Commission (the “FERC”) for authority to borrow on a short-term, revolving basis up to a maximum of $350 million in connection with a credit facility pursuant to its “Application of NorthWestern Corporation for Authorization Under Section 204 of the Federal Power Act and Request for Shortened Comment Period” dated May 20, 2011, Docket No. ES11-34-000. The FERC authorized the Borrower, pursuant to Section 204 and consistent with the foregoing application, to borrow under a senior credit facility in an amount not to exceed $350 million, pursuant to the FERC's Order dated June 20, 2011, Docket No. ES11-34-000

2.The Montana Public Service Commission (“MPSC”) takes the position that its approval is required in connection with the issuance of debt by entities subject to the regulation and oversight of the MPSC. The Borrower is subject to the regulation and oversight of the MPSC in connection with its conduct of the utility business in the State of Montana, including, without limitation, with respect to the issuance of debt securities specifically relating to such business. Without conceding its position that the MPSC may not have jurisdiction over this financing, the Borrower filed with the MPSC its application, dated November 29, 2010, pursuant to the Montana Code Annotated §§ 69-3-501 through 69-3-507, seeking, among other things, authorization for the Borrower to issue unsecured debt securities in an amount not to exceed $350 million. Pursuant to the MPSC's Final Order dated December 14, 2010, the MPSC authorized the Borrower, consistent with the foregoing application, to issue unsecured debt securities in an amount not to exceed $350 million.

SCHEDULE 4.17

ENVIRONMENTAL

Section 4.17 (a)(i)-(iv):

As set forth in the Borrower's SEC Reports, the Borrower holds certain joint ownership interests in power generation facilities that service its South Dakota utility load. These power plants are fueled by coal. The United Stated Environmental Protection Agency (“EPA”) is conducting an enforcement initiative at a number of coal-fired power plants across the United States in an effort to determine whether modifications at those facilities were subject to New Source Review requirements or New Source Performance Standards under the Clean Air Act. In connection with this initiative, the EPA has requested information from the Borrower regarding certain of its South Dakota operations under Section 114(a) of the Clean Air Act (Section 114). The EPA has issued similar requests to certain power plants previously owned by The Montana Power Company, including the ▇▇▇▇▇▇▇▇ and Colstrip power plants, the latter of which the Borrower continues to own a 30% interest in Unit #4. The Section 114 information requests required that the Borrower provide responses to specific EPA questions regarding certain projects and maintenance activities that the EPA believes could have violated the New Source Performance Standard and New Source Review requirements of the Clean Air Act. The EPA contends that power plants are required to update emission controls at the time of major maintenance or capital activity. The Borrower believes that maintenance and capital activities preformed at its jointly-owned power plants were routine in nature and typical for the industry. The Borrower has complied and continues to comply with these information requests, the EPA has not filed an enforcement action against the Borrower, but the Borrower cannot predict the outcome of this investigation at this time. Should the EPA determine to take action, the resulting additional costs to comply could be material.


2.	The Borrower owns or previously owned real property upon which manufactured gas plants previously operated in the states of Montana, South Dakota and Nebraska.

Contamination may continue to exist in soils at these locations in levels that exceed certain state or federal environmental standards and which may impact or already may have impacted groundwater and which require further remediation. At present, the Borrower cannot estimate with a reasonable degree of certainty the total costs of any cleanup at these locations. Based upon findings from prior investigations, the Borrower's current environmental liability reserves, applicable insurance coverage, and the Borrower's belief that it will be able to recoup prudently incurred costs in rates, the Borrower does not expect cleanup costs at these locations to be material.

In 2010, Borrower responded to an information request to The ▇▇▇▇▇ Fork and Blackfoot L.L.C. from the U.S. Environmental Protection Agency regarding its relationship to properties in the Great Falls area that were formerly owned and operated by the Montana Power Company, and that might contain contamination related to the ACM Smelter and Refinery Site (ACM Site), which had then been proposed for listing on the National Priorities List for cleanup under the Superfund. In June 2011, after the ACM Site was formally listed on the NPL, EPA sent special notice letters regarding the ACM Site to the smelter owner, Atlantic Richfield, and to BNSF railroad, demanding that those parties submit a good faith proposal for conducting the investigation of the property within sixty days. EPA also sent a general notice letter to Borrower with respect to the former BNSF railroad right of way property which EPA has proposed for investigation and possible remediation as part of the ACM Site. Borrower is the current owner of a portion of the rail bed, which Montana Power had purchased from BNSF, and may have indemnification obligations with respect to other portions of the rail bed. EPA has not requested that Borrower participate in the remedial investigation. However, it is anticipated that Borrower, as current owner of a portion of the property, will become involved in that investigation process. Borrower does not expect the outstanding cleanup costs to be material.

Section 4.17(b)(i)-(iii):


1.	See discussion above regarding the Borrower's former manufactured gas plant locations.

Based upon discovery of organic wastes (PCBs & hydrocarbons) at the Montana Street Operating Center (“MSOC”), the State of Montanan Solid & Hazardous Waste Bureau notified The Montana Power Company of its intent to perform a preliminary assessment at the site for possible inclusion on the NPL. Before the MSOC site was scored, the USEPA notified The Montana Power Company that the property was located within the existing Butte Priority Soils Operable Unit (“BPSOU”) Superfund site. The Montana Power Company negotiated a “de minimis” settlement with the EPA for its liability with the BPSOU site, settling most of its liability in a Consent Decree approved by the United States District Court for the District of Montana, and received contribution protection in the event other potentially responsible parties' claim contribution for related cleanup costs. The MSOC site may be subject to future regulatory action or voluntary cleanup activities for organic compounds found in the soil (TPH, PCBs) at its Montana Street site. The Borrower assumed this potential liability under the terms of its acquisition of the utility assets of The Montana Power Company and cannot estimate with a reasonable degree of certainty the total costs, if any, for cleanup of this site. The Borrower does not expect cleanup costs to be material.


3.	In April 1998, the Montana Power company identified and reported a release of

hydrocarbons during the replacement of a dispensing unit associated with an underground storage tank located at its Helena Operating Center. Impacted soils were removed and groundwater monitoring ▇▇▇▇▇ were installed. With the acquisition of the Montana Power Company, Borrower succeeded to the liability associated with the site. To date, hydrocarbons remain detectable at low levels in groundwater and soil vapor extraction efforts are underway to remove the contaminants. Borrower does not expect the outstanding cleanup costs to be material.
