Section 4.    Modification of Special Provisions Applicable to LIBOR Borrowings. Section 2.05 of the Credit Agreement is hereby amended and restated in its entirety to hereafter read as follows:

(a)    If prior to the commencement of any Interest Period for a LIBOR Borrowing:

(i)     Lender determines (which determination shall be conclusive and binding absent manifest error) that adequate and reasonable means do not exist for ascertaining (including, without limitation, by means of an Interpolated Rate) the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(ii)     Lender determines the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to Lender of making or maintaining its Loan included in such Borrowing for such Interest Period;

then Lender shall give notice thereof to the Borrower by telephone, fax or through Electronic System as provided in Section 8.08 as promptly as practicable thereafter and, until Lender notifies the Borrower that the circumstances giving rise to such notice no longer exist, (x) any Rate Selection Notice that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a LIBOR Borrowing shall be ineffective and any such LIBOR Borrowing shall be repaid on the last day of the then current Interest Period applicable thereto, and (y) if any Rate Selection Notice requests a LIBOR Borrowing, such Borrowing shall be made as a CBFR Borrowing.

(b)    Borrower hereby agrees to indemnify Lender against and hold Lender harmless from any actual loss or expense that Lender may sustain or incur as a consequence of (i) failure by Borrower to timely convert or borrow any LIBOR Borrowing after Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (ii) failure by Borrower to make any prepayment after Borrower has given a notice thereof in accordance with the provisions of this Agreement or (iii) the making of a payment or prepayment of any LIBOR Borrowing, or the conversion of any LIBOR Borrowing, on a day that is not the last day of an Interest Period with respect thereto, including without limitation, in each case, any such loss or expense arising from the liquidation or reemployment of funds obtained by Lender or from fees payable to terminate the deposits from which such funds were obtained.

(c)    If Borrower requests quotes of the Adjusted LIBOR Rate for different Interest Periods being considered for election by Borrower, Lender will use reasonable efforts to provide such quotes to Borrower promptly. However, all such quotes provided shall be representative only and shall not be binding on Lender, nor shall they be determinative, directly or indirectly, of any Adjusted LIBOR Rate or any component of any such rate, nor will Borrower's failure to receive or Lender's failure to provide any requested quote or quotes either (1) excuse or extend the time for performance of any obligation of Borrower or for the exercise of any right, option or election of Borrower or (2) impose any duty or liability on Lender. If Borrower requests a list of the Business Days in any calendar month, Lender will use reasonable efforts to provide such list promptly. However, any such list provided shall be understood to identify only those days which Lender believes in good faith at the time such list is prepared will be the Business Days for such month. Lender shall not have any liability for any failure to provide, delay in providing, error or mistake in or omission from, any such quote or list.

(d)    With respect to Lender having a LIBOR Lending Office which differs from its Domestic Lending Office, all Loans that are part of LIBOR Borrowings advanced by Lender's LIBOR Lending Office shall be deemed to have been made by Lender and the obligation of Borrower to repay such Loans shall nevertheless be to Lender and shall be deemed held by Lender for the account of Lender's LIBOR Lending Office.

Section 5.    Modification of Increased Costs Provisions. Section 2.06 of the Credit Agreement is hereby amended and restated in its entirety to hereafter read as follows:

Section 2.06     Increased Costs.

(a)    If Lender reasonably determines that any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, liquidity or similar requirement (including any compulsory loan requirement, insurance charge or other assessment) against assets of, deposits with or for the account of, or credit extended by, Lender (except any such reserve requirement reflected in the Adjusted LIBOR Rate);

(ii) impose on Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or any Loans made hereunder; or

(iii) subject Lender to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clause (b) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto,

and the result of any of the foregoing shall be to increase the cost to Lender of making, continuing, converting into or maintaining any Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by Lender hereunder (whether of principal, interest or otherwise), then Borrower will pay to Lender such additional amount or amounts as will compensate Lender for such additional costs incurred or reduction suffered.

(b)    If Lender reasonably determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on Lender’s capital or on the capital of Lender’s holding company as a consequence of this Agreement, the Commitment of or the Loans made by Lender to a level below that which Lender or Lender’s holding company could have

achieved but for such Change in Law (taking into consideration Lender’s policies and the policies of Lender’s holding company with respect to capital adequacy and liquidity), then from time to time Borrower will pay to Lender such additional amount or amounts as will compensate Lender or Lender’s holding company for any such reduction suffered; provided, however, that notwithstanding the foregoing, if Borrower (i) fully pays all outstanding Obligations, (ii) pays to Lender, in immediately available funds, an amount equal to 105% of the then aggregate amount available for drawings under all outstanding Letters of Credit, if any (which funds shall be held by Lender as Cover for said Letters of Credit), and (iii) irrevocably terminates the Commitment in writing delivered to Lender, all within twenty (20) days after Borrower’s receipt of any notice from Lender that amounts are or will be owing by Borrower to Lender pursuant to the terms of this Section 2.06, then in such event, Borrower shall not be obligated to pay to Lender any such amounts to the extent, but only to the extent, such amounts are attributable to any period prior to the date of Borrower’s receipt of such notice from Lender.

(c)    A certificate of Lender setting forth the amount or amounts necessary to compensate Lender or its holding company, as the case may be, as specified in Sections 2.06(a) or 2.06(b) shall be delivered to Borrower, demonstrating in reasonable detail the calculation of the amounts. Borrower shall pay amounts due under this Section 2.06 within ten (10) days after receipt of the corresponding certificate.

(d)    Failure or delay on the part of Lender to demand compensation pursuant to this Section shall not constitute a waiver of Lender’s right to demand such compensation; but Borrower shall not be required to compensate Lender pursuant to this Section for any increased costs or reductions incurred more than 180 days before the date that Lender notifies Borrower of the Change in Law giving rise to such increased costs or reductions and of Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive and if Lender notifies Borrower of such Change of Law within 180 days after the adoption, enactment or similar act with respect to such Change of Law, then the 180-day period referred to above shall be extended to include the period from the effective date of such Change of Law to the date of such notice.

Section 6.    Addition of Taxes Provisions. A new Section 2.09 is hereby added to the Credit Agreement to hereafter read as follows:

Section 2.09    Taxes.

(a)    Withholding Taxes; Gross-Up; Payments Free of Taxes. Any and all payments by or on account of any obligation of Borrower under any Credit Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 2.09), Lender receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b)    Payment of Other Taxes by Borrower. Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Lender, timely reimburse it for, Other Taxes.

(c)    Evidence of Payment. As soon as practicable after any payment of Taxes by Borrower to a Governmental Authority pursuant to this Section 2.09, Borrower shall deliver to the Lender the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment, or other evidence of such payment reasonably satisfactory to Lender.

(d)    Indemnification by Borrower. Borrower shall indemnify Lender, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by Lender or required to be withheld or deducted from a payment to Lender and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Borrower by Lender shall be conclusive absent manifest error.

(e)    Treatment of Certain Refunds. If Lender determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.09 (including by the payment of additional amounts pursuant to this Section), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.09 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of Lender, shall repay to Lender the amount paid to Lender (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (e), in no event will Lender be required to pay any amount to any indemnifying party pursuant to this paragraph (e), the payment of which would place Lender in a less favorable net after-Tax position than Lender would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph (e) shall not be construed to require Lender to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(f)    Survival. Each party’s obligations under this Section 2.09 shall survive the resignation or replacement of Lender or any assignment of rights by, or the replacement of, Lender, the termination of the Commitment and the repayment, satisfaction or discharge of all obligations under any Credit Document.

(g)    Defined Terms. For purposes of this Section 2.09, the term “applicable law” includes FATCA.

Section 7.    Not FATCA “Grandfathered Obligation”. For purposes of determining withholding Taxes imposed under FATCA, from and after the effective date of this Amendment, Borrower and Lender shall treat the Credit Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).

Section 8.    Addition of Anti-Corruption Laws and Sanctions Provisions.

(a)    Section 5.09 of the Credit Agreement is hereby amended and restated in its entirety to hereafter read as follows:

Section 5.09    Loan Proceeds. The proceeds of the Loans will be used to provide funds for working capital, acquisition needs, capital expenditures and general corporate purposes for Borrower. Borrower will not request any Loan or Letter of Credit, and Borrower shall not use, and Borrower shall procure that its Subsidiaries and its directors, officers, employees and agents shall not use, the proceeds of any Loan (a) in furtherance of an offer, payment, promise to pay, or authorization of the payment or giving of money, or anything else of value, to any Person in violation of any Anti-Corruption Laws, (b) for the purpose of funding, financing or facilitating any activities, business or transaction of or with any Sanctioned Person, or in any Sanctioned Country, to the extent such activities, businesses or transaction would be prohibited by Sanctions if conducted by a corporation incorporated in the United States or the European Union or (c) in any manner that would result in the violation of any Sanctions applicable to any party hereto.

(b)    New Sections 4.20 and 5.12 are hereby added to the Credit Agreement to hereafter read as follows:

Section 4.20    Anti-Corruption Laws and Sanctions. Each Obligor has implemented and maintains in effect policies and procedures designed to ensure compliance by such Obligor, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and such Obligor, its Subsidiaries and their respective officers and employees and, to the knowledge of such Obligor, its directors and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects. None of (a) any Obligor, any Subsidiary or any of their respective directors, officers or employees, or (b) to the knowledge of any such Obligor or Subsidiary, any agent of any such Obligor or any such Subsidiary that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person.
