(i) on the 90th day after the Closing Date, a fully earned and non-refundable duration fee equal to 0.50% of the aggregate principal amount of Loans of such Lender then outstanding;

(ii) on the 180th day after the Closing Date, a fully earned and non-refundable duration fee equal to 0.75% of the aggregate principal amount of Loans of such Lender then outstanding; and

(iii) on the 270th day after the Closing Date, a fully earned and non-refundable duration fee equal to 1.00% of the aggregate principal amount of Loans of such Lender then outstanding.

(c) 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).

2.5. Termination or Reduction of Commitments.

(a) Unless previously reduced or terminated in accordance with this Agreement, (i) each Lender’s Commitment shall automatically and permanently reduce by the amount of each Loan made by such Lender, and (ii) each Lender’s Commitments shall automatically and permanently terminate on the earlier of (A) the funding of the Loans on the Closing Date in accordance with Section 2.01 and (B) the Commitment Termination Date.

(b) 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 Commitments or, from time to time, to reduce the aggregate amount of the Commitments. Any such reduction shall be in an amount equal to $1,000,000, or a whole multiple thereof, and shall reduce permanently the Commitments then in effect.

(c) Upon the occurrence of any Reduction Event prior to the funding of the Loans on the Closing Date, the Commitments shall be automatically and permanently reduced by an amount equal to the Net Cash Proceeds of such Reduction Event. The Borrower shall notify the Administrative Agent of any Reduction Event and the Net Cash Proceeds thereof no later than the date of such Reduction Event, and the Administrative Agent shall promptly notify the Lenders of such Reduction Event.

2.6. Optional and Mandatory Prepayments.

(a) 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 2.15), 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 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 2.15. Upon receipt of any such notice, the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with accrued interest to such date on the amount prepaid. Partial

prepayments of Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple thereof.

(b) Upon the occurrence of any Reduction Event after the funding of the Loans on the Closing Date, the Borrower shall prepay Loans in a principal amount equal to the Net Cash Proceeds of such Reduction Event. Any such prepayment shall be effected within three Business Days after receipt of such Net Cash Proceeds. The Borrower shall notify the Administrative Agent of any Reduction Event and the Net Cash Proceeds thereof not later than the date of such Reduction Event, and the Administrative Agent shall promptly notify the Lenders of such Reduction Event.

2.7. Conversion and Continuation Options.

(a) The Borrower may elect from time to time to convert Eurodollar Loans to Base Rate Loans by giving the Administrative Agent at least one Business Day prior irrevocable notice, no later than 11:00 a.m., New York City time, 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 to Eurodollar Loans by giving the Administrative Agent irrevocable notice of such election no later than 11:00 a.m., 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 one month (or if agreed to by all Lenders, two weeks) prior to the Maturity Date. Upon receipt of any such notice, the Administrative Agent shall promptly notify each Lender thereof.

(b) The Borrower may elect to continue any Eurodollar Loan 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 one month (or if agreed to by all Lenders, two weeks) prior to the 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.

2.8. 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 seven Eurodollar Tranches shall be outstanding at any one time.

2.9. 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.

(b) 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.

(c) (i) If all or a portion of the principal amount of any Loan shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), the amount of principal of such Loan which is overdue shall bear interest at a rate per annum equal to the rate that would otherwise be applicable to such Loan pursuant to the foregoing provisions of this Section 2.9 plus 2% and (ii) if all or a portion of any interest payable on any Loan 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).

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

2.10. 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.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.9(a).

2.11. 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, 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.

2.12. Pro Rata Treatment and Payments.

(a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee, and any reduction of the Commitments of the Lenders, shall be made pro rata according to the Pro Rata Shares 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.

(b) Each payment (including each prepayment) by the Borrower on account of principal of the Loans shall be made pro rata according to the respective outstanding principal amounts of the Loans then held by the Lenders.

(c) 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 shall be accompanied by accrued interest to the date of such payment on the amount paid.

(d) 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. Any payment made by the Borrower after 12:00 Noon, New York City time, on any Business Day shall, in the Administrative Agent’s sole discretion, be deemed to have been on the next following Business Day. Except as otherwise provided herein, if any payment hereunder becomes due and payable, or the performance of any

covenant, duty or obligation is stated to be due or required, on a day other than a Business Day, such payment or performance 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.

(e) 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 Closing Date, 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 the Closing 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.

(f) 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.

(g) 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.

2.13. 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 any Loan made by it, other than Non-Excluded Taxes covered by Section 2.14 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 Loans, 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.

(b) If any Lender shall have reasonably determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or liquidity 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 or liquidity (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 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 or liquidity) 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.

(c) 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.

2.14. Taxes.

(a) All payments made by or on account of any obligation of the Borrower under any Loan Document 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 (except as required by Law), excluding taxes imposed on or measured by net income, franchise taxes and branch profits taxes, in each case (i) imposed on the Administrative Agent or any Lender as a result of the Administrative Agent or such Lender being organized under the Laws of, or having its principal office or, in the case of any Lender, applicable lending office located in, the jurisdiction imposing the tax or (ii) a present or former connection between the Administrative 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 the Administrative 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 the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes, including all such amounts applicable to additional sums payable under this Section 2.14) interest and all other amounts payable at the rates or in the amounts specified in the applicable Loan Documents; 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 or the Administrative Agent’s failure to comply with the requirements of paragraph (d) or (e) of this Section, as applicable, (ii) that are United States withholding taxes imposed on amounts payable to or for the account of such Lender at 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) or (iii) any U.S. federal withholding taxes imposed under FATCA.

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

(c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as practicable thereafter the Borrower shall send to the Administrative Agent for the account of the Administrative Agent or relevant 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 Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative 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.

(d) 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). Any Non-U.S. Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by such recipient) on or prior to the date on which such Non-U.S. Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding tax, duly completed, together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made. 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. Any Lender that is a “U.S. Person” as defined in Section 7701(a)(30) of the Code shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax. In addition, any Lender, if reasonably requested by Borrower, shall deliver such other documentation as will enable the Borrower to determine whether or not such Lender is subject to

backup withholding or information reporting. Notwithstanding anything to the contrary in this Section 2.14(d), the completion, execution and submission of such documentation (other than the Form W-8BEN, the Form W-8ECI, the statement provided in Exhibit E and the Form W-9 described in this Section 2.14(d) and the documentation described below in Section 2.14(g)) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(e) 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.

(f) The Borrower shall, subject to the limitations provided in subclauses (i) through (iii) in the last sentence of Section 2.14(a), indemnify the Administrative Agent and each Lender, within 10 days after demand therefor, for the full amount of any Non-Excluded Taxes and Other Taxes (including any Non-Excluded Taxes and Other Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by the Administrative Agent or such Lender or required to be withheld or deducted from a payment to the Administrative Agent or such Lender and any reasonable expenses arising therefrom or with respect thereto, whether or not such taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by the Administrative Agent or the applicable Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of such Lender, shall be conclusive absent manifest error.

(g) If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by Law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.14(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

2.15. 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, (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 2.18. 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.

2.16. 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 2.15.

2.17. Change of Lending Office.

SECTION 8. THE ADMINISTRATIVE AGENT

Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents, and each Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities,

duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent.

8.2. Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

8.3. Exculpatory Provisions. Neither the Administrative 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 Administrative Agent 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 Administrative Agent 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.

8.4. Reliance by the Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 9.6 and all actions required by such Section in connection with such transfer shall have been taken. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders 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. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders 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.

8.5. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless it shall have received written 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.

8.6. Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by the Administrative 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 the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative 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 the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower and its affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or any affiliate of the Borrower that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

8.7. Indemnification. The Lenders agree to indemnify the Administrative 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 Pro Rata Shares 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 Pro Rata Shares immediately prior to such date), for, and to save the Administrative 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 at any

time following the payment of the Loans) be imposed on, incurred by or asserted against the Administrative 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 the Administrative 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.

8.8. Administrative Agent in Its Individual Capacity. The Administrative 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 the Administrative Agent were not an agent hereunder. With respect to its Loans made or renewed by it, the Administrative 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 hereunder, and the terms “Lender” and “Lenders” shall include the Administrative Agent in its individual capacity.

8.9. 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 7(a) or Section 7(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 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. After any retiring Administrative Agent’s resignation as such agent hereunder, the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was an agent under this Agreement and the other Loan Documents.

8.10. The Joint Lead Arrangers; the Syndication Agent; the Documentation Agent. Neither the Joint Lead Arrangers, nor the Syndication Agent nor the Documentation Agent, 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.

(b) 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, (x) 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 (y) 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 the Administrative Agent may, with the consent of the Borrower only and without the need to obtain the consent of any Lender, amend, supplement or modify this Agreement or any other Loan Document to cure any ambiguity, omission, defect or inconsistency, so long as such amendment, supplement or modification does not adversely affect the rights of any Lender; provided, further, 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, 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, reduce any percentage specified in the definition of Required Lenders or consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan Documents, 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 Facility set forth in Section 4.2 (including 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 all 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 8, or any other provision affecting the rights, duties or obligations of any Agent, without the consent of any Agent directly affected thereby;

(vi) amend, modify or waive any provision of Section 2.12 or 9.7 without the consent of each Lender directly affected thereby;

(vii) impose restrictions on assignments and participations that are more restrictive than, or additional to, those set forth in Section 9.6 without the consent of all the Lenders; or

(viii) except as provided in Section 2.19, change any provision hereof in a manner that would alter the pro rata sharing of payments required by Section 2.12, without the written consent of each Lender whose pro rata share could otherwise be reduced thereby.

(c) Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Borrower, the Lenders, the Administrative Agent and all future holders of the Loans. In the case of any waiver, the Borrower, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. 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.

(d) 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 Loans 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.

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

(b) The Borrower hereby acknowledges that (i) the Administrative Agent may, but shall not be obligated to make available to the Lenders materials and/or information provided by, or on behalf of, the Borrower hereunder (collectively, the “Borrower Materials”) by posting the Borrower Materials on Intralinks or another similar electronic system (the “Platform”) and (ii) certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to receive material nonpublic information with respect to the Borrower or its securities) (each, a “Public Lender”). The Borrower hereby agrees that (A) all Borrower Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof, (B) by marking Borrower Materials “PUBLIC,” the Borrower shall be deemed to

have authorized the Administrative Agent and the Lenders to treat such Borrower Materials as not containing any material nonpublic information with respect to the Borrower or its securities for purposes of United States Federal and state securities laws (provided that to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 9.1), (C) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform designated as “Public Investor” and (D) the Administrative Agent shall be entitled to treat any Borrower Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not marked as “Public Investor.” Notwithstanding the foregoing, the following Borrower Materials shall be deemed to be marked “PUBLIC” unless the Borrower has a reasonable time to review such Borrower Materials and promptly notifies the Administrative Agent that any such document contains material nonpublic information: (1) the Loan Documents, (2) any notification of changes in the terms of the Credit Facilities and (3) all information delivered pursuant to Sections 5.1 and 5.2(b).

(c) Each Public Lender agrees to cause at least one individual at or on behalf of such Public Lender to at all times have selected the “Private Side Information” or similar designation on the content declaration screen of the Platform in order to enable such Public Lender or its delegate, in accordance with such Public Lender’s compliance procedures and applicable law, including United States Federal and state securities laws, to make reference to Borrower Materials that are not made available through the “Public Side Information” portion of the Platform and that may contain material non-public information with respect to the Borrower or its securities for purposes of United States Federal or state securities laws.

(d) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” NEITHER THE ADMINISTRATIVE AGENT NOR ANY OF ITS AFFILIATES WARRANTS THE ACCURACY OR COMPLETENESS OF THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM AND EACH EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS IN THE BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT OF THIRD-PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS IS MADE BY THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES HAVE ANY LIABILITY TO ANY LENDER OR ANY OTHER PERSON FOR DAMAGES OF ANY KIND, WHETHER OR NOT BASED ON STRICT LIABILITY AND INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF ANY LENDER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF BORROWER MATERIALS THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY SUCH PERSON IS FOUND IN A FINAL RULING BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH PERSON’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

9.3. No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver

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

9.4. Survival of Representations and Warranties. All representations and warranties made herein, in the other Loan Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Loans and other extensions of credit hereunder.

9.5. Payment of Expenses. The Borrower agrees (a) to pay or reimburse the Administrative Agent for all its reasonable and documented or invoiced out-of-pocket costs and expenses incurred in connection with the syndication of the Facilities (including legal expenses (but limited to expenses of one legal counsel and, if reasonably necessary or advisable, of one regulatory counsel and a single local counsel in any relevant jurisdiction)) (other than fees payable to syndicate members) and the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including the reasonable fees and disbursements and other charges of counsel to the Administrative Agent and the charges of Intralinks, (b) to pay or reimburse the Administrative Agent and, if incurred during the continuance of an Event of Default, each Lender for all their costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any other documents prepared in connection herewith or therewith, including the fees and disbursements of counsel to such Person (including the allocated fees and disbursements and other charges of in-house counsel, but otherwise limited to expenses of one legal counsel and, if reasonably necessary or advisable, of one regulatory counsel and a single local counsel in any relevant jurisdiction for all such Persons unless, in the reasonable opinion of any such Person, representation of all such Persons by such counsel would be inappropriate due to the existence of an actual or potential conflict of interest), (c) to pay, indemnify, or reimburse each Lender, and the Administrative Agent for, and hold each Lender, and the Administrative Agent harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify or reimburse each Lender, each Agent, their respective Affiliates, successors and assigns, and their respective officers, directors, trustees, employees, advisors, agents, controlling persons and members (each, an “Indemnitee”) for, and hold each Indemnitee harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever incurred by an Indemnitee or asserted against any Indemnitee by any third party or by the Borrower arising out of, in connection with, or as a result of (and in each case regardless of whether such matter is initiated by a third party or by the Borrower or the Seller or any of their respective Affiliates or equity holders) (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the

performance by the parties hereto or thereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or release of Materials of Environmental Concern on or from any property owned, occupied or operated by the Borrower or any of its Subsidiaries, or any liability related to any Environmental Law related in any way to the Borrower or any of its Subsidiaries or any of their respective properties, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by any third party or by the Borrower, and regardless of whether any Indemnitee is a party thereto (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”); provided that no Indemnitee will be indemnified for any claim, loss, damage, liability or expense to the extent the same resulted from (A) the gross negligence, bad faith or willful misconduct of the respective Indemnitee, any of its Affiliates or their respective officers, directors, trustees, employees, advisors, agents, controlling persons and members (as determined by a court of competent jurisdiction in a final and non-appealable judgment), (B) any claim, litigation, investigation or proceeding solely between or among Indemnified Persons other than actions against the Administrative Agent, the Joint Lead Arrangers or other persons acting in an agency or similar role in their capacity as such (and which does not involve an act or omission of the Borrower or any of its affiliates) and (C) any legal expenses in excess of the expenses of one legal counsel and, if reasonably necessary or advisable, of one regulatory counsel and a single local counsel in any relevant jurisdiction for all Indemnitees unless, in the reasonable opinion of an Indemnitee, representation of all Indemnitees by such counsel would be inappropriate due to the existence of an actual or potential conflict of interest. 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 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: (▇▇▇) ▇▇▇-▇▇▇▇; Fax: (▇▇▇) ▇▇▇-▇▇▇▇; Email: ▇▇▇▇▇.▇▇▇▇@▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇), at the address of the Borrower set forth in Section 9.2, or to such other Person or address as may be hereafter designated by the Borrower in a notice to the Administrative Agent. The agreements in this Section shall survive repayment of the Loans and all other amounts payable hereunder.

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

(b) 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 Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Loans or any fees or other amounts payable hereunder, in each case to the extent subject to such participating interest, or postpone any date fixed for any payment of principal of, or interest on, the Loans or any fees or other amounts payable hereunder or extend or increase any Commitment hereunder, in each case to the extent subject to such participating interest. The Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement; provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 9.7(a) as fully as if such Participant were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits and subject to the obligations of Sections 2.13, 2.14 and 2.15 with respect to its participation in the Commitments and the Loans outstanding from time to time as if such Participant were a Lender or Assignee under Section 9.6(c); provided that, in the case of Section 2.14, such Participant shall have complied with the requirements of said Section; and provided, further, that (A) such Participant agrees to be subject to the provisions of Sections 2.17 and 2.18 as if it were an Assignee under Section 9.6(c) and (B) no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive

absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(c) Any Lender (an “Assignor”) may, 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 or Related Fund of a Lender or, with the consent of the Borrower and the Administrative Agent (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 or the Administrative Agent is required pursuant to the foregoing provisions, by the Borrower and the Administrative Agent) and delivered to the Administrative Agent via an electronic settlement system acceptable to the Administrative Agent or, if previously agreed with the Administrative Agent, manually, for its acceptance and recording in the Register together with a processing and recordation fee of $3,500 (which fee may be waived or reduced in the sole discretion of the Administrative Agent) and, if the Assignee shall not be a Lender, deliver to the Administrative Agent an administrative questionnaire and all applicable tax forms; provided that with respect to assignments of 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 $2,500,000 and increments of $1,000,000 in excess thereof (other than in the case of an assignment of all of a Lender’s interests under this Agreement), unless otherwise agreed by the Borrower and the Administrative Agent and provided further that (i) from the Closing Date, no such consent of the Borrower to assignments shall be required, and (ii) no consent of the Borrower shall be required to a Permitted Assignee (and the Administrative Agent shall notify the Borrower of any assignment made pursuant to this clause (ii)). 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 2.13, 2.14 and 9.5, 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 set forth in this paragraph, multiple assignments to or by two or more Related Funds shall be aggregated.

(d) No such assignment shall be made (i) to the Borrower or any of the Borrower’s Affiliates or Subsidiaries or (ii) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii).

(e) No such assignment shall be made to a natural Person.

(f) 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. 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.

(g) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and 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, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Loans and any Notes evidencing 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). 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.

(h) 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 9.6(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, if applicable, an Administrative Questionnaire completed in respect of the Assignee (unless the Assignee shall already be a Lender hereunder) and any applicable tax forms, 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. 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 Note of the assigning Lender) a new Note to the order of such Assignee in an amount equal to the Commitment assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Commitment, upon request, a new Note to the order of the Assignor in an amount equal to the 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.

(i) 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 any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank in accordance with applicable law.

(j) 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 9.6(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.

9.7. 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 the Facility; and except as expressly provided herein with respect to Defaulting Lenders, 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 7(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of 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.

(b) 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, 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, agency or Affiliate 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; and 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 2.19 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.

9.8. Counterparts.

9.15. Accounting Changes. In the event that any Accounting Change shall occur and such change results in a change in the method of calculation of financial covenants, standards or terms in this Agreement, then the Borrower, the Lenders and the

Administrative Agent agree to enter into good faith negotiations in order to amend such provisions of this Agreement so as to equitably reflect such Accounting Change with the desired result that the criteria for evaluating the Borrower’s financial condition shall be the same after such Accounting Change as if such Accounting Change had not been made.

FORM OF SOLVENCY CERTIFICATE

[__], 2013

This Solvency Certificate (“Certificate”) of NorthWestern Corporation d/b/a NorthWestern Energy, a Delaware corporation (“NorthWestern” or the “Borrower”), and its Subsidiaries is delivered pursuant to Section 4.2(c) of the $900,000,000 Senior Bridge Credit Agreement dated as of November 12, 2013 (the “Credit Agreement”) by and among the Borrower, the Lenders from time to time party thereto, and Credit Suisse AG, as Administrative Agent. Unless otherwise defined herein, capitalized terms used in this Certificate shall have the meanings set forth in the Credit Agreement.

I, [▇▇▇▇▇ ▇. ▇▇▇▇], the duly elected, qualified and acting [Vice President and Chief Financial Officer] of NorthWestern and its Subsidiaries, DO HEREBY CERTIFY, as follows:

1. I have reviewed the Credit Agreement and the other Loan Documents referred to therein (collectively, the “Transaction Documents”) and have made such investigation as I have deemed necessary to enable me to express a reasonably informed opinion as to the matters referred to herein.

2. As of the date hereof, after giving effect to the Transactions, the fair value and the present fair saleable value of any and all property of NorthWestern and its Subsidiaries, on a consolidated basis, is greater than the probable liability on existing debts of NorthWestern and its Subsidiaries, on a consolidated basis, as they become absolute and matured (it being understood that the amount of contingent liabilities at any time shall be computed as the amount that, in the light of all the facts and circumstances existing as of the date hereof, represents the amount that can reasonably be expected to become an actual or matured liability).

3. As of the date hereof, after giving effect to the Transactions, NorthWestern and its Subsidiaries, on a consolidated basis are able to pay their debts (including, without limitation, contingent and subordinated liabilities) as they become absolute and mature (it being understood that the amount of contingent liabilities at any time shall be computed as the amount that, in the light of all the facts and circumstances existing as of the date hereof, represents the amount that can reasonably be expected to become an actual or matured liability).

4. As of the date hereof, after giving effect to the Transactions, NorthWestern and its Subsidiaries, on a consolidated basis are otherwise “solvent” within the meaning given that term and similar terms under applicable laws relating to fraudulent transfers and conveyances.

5. NorthWestern and its Subsidiaries, on a consolidated basis, do not intend to, nor do they believe that they will, incur debts that would be beyond their ability to pay as such debts mature.

6. As of the date hereof, before and after giving effect to the Transactions, NorthWestern and its Subsidiaries are not engaged in businesses or transactions, nor about to engage in businesses or transactions, for which any property remaining would, on a consolidated

G-1

basis, constitute unreasonably small capital after giving due consideration to the prevailing practice in the industry in which they are engaged.

7. For the purpose of the foregoing, I have assumed there is no default under the Credit Agreement on the date hereof and will be no default under the Credit Agreement after giving effect to the funding under the Credit Agreement.
