(a)    Section 2.14 is amended by replacing it in its entirety with the following:

“Section 2.14 Basis for Determining Interest Rate Inadequate, Unfair or Unavailable.

(a) If on or prior to the first day of any Interest Period for any Euro-Dollar Loan: (i) Lenders having 50% or more of the aggregate amount of the Commitments advise the Administrative Agent that the Adjusted London Interbank Offered Rate as determined by the Administrative Agent, will not adequately and fairly reflect the cost to such Lenders of funding their Euro-Dollar Loans for such Interest Period; or (ii) the Administrative Agent shall determine that no reasonable means exists for determining the Adjusted London Interbank Offered Rate, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such suspension no longer exist, (x) the obligations of the Lenders to make Euro-Dollar Loans, or to convert outstanding Loans into Euro-Dollar Loans shall be suspended; and (y) each outstanding Euro-Dollar Loan shall be converted into a Base Rate Loan on the last day of the current Interest Period applicable thereto. Unless the Borrower notifies the Administrative Agent at least two (2) Business Days before the date of (or, if at the time the Borrower receives such notice the day is the date of, or the date immediately preceding, the date of such Euro-Dollar Borrowing, by 10:00 A.M. (Charlotte, North Carolina time) on the date of) any Euro-Dollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date (in which case the Borrower shall not be subject to any liability pursuant to Section 2.12 with

respect to such election), such Borrowing shall instead be made as a Base Rate Borrowing.

(b) Notwithstanding anything to the contrary in this Agreement or any other Loan Document, if the Administrative Agent determines (which determination shall be conclusive absent manifest error), or the Borrower or Required Lenders notify the Administrative Agent (with, in the case of the Required Lenders, a copy to the Borrower) that the Borrower or Required Lenders (as applicable) have determined, that:

(i)    the circumstances set forth in Section 2.14(a)(ii) have occurred and such circumstances are unlikely to be temporary; or

(ii)    the administrator of the London Interbank Offered Rate or a Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the London Interbank Offered Rate shall no longer be made available, or used for determining the interest rate of loans (such specific date, the “Scheduled Unavailability Date”), or

(iii)    any applicable interest rate specified herein (other than the Prime Rate or the Federal Funds Rate) is no longer a widely recognized benchmark rate for newly originated loans in the U.S. syndicated loan market in the applicable currency,

then, reasonably promptly after such determination by the Administrative Agent or receipt by the Administrative Agent of such notice, as applicable, the Administrative Agent and such Borrower shall negotiate in good faith to amend this Agreement to replace the London Interbank Offered Rate with an alternate benchmark rate (including any mathematical or other adjustments to the benchmark (if any) incorporated therein) (any such proposed rate, a “LIBOR Successor Rate”), together with any proposed LIBOR Successor Rate Conforming Changes (as defined below) and any such amendment shall become effective at 5:00 P.M. (Charlotte, North Carolina time) on the fifth Business Day after the Administrative Agent shall have posted such proposed amendment to all Lenders and the Borrower unless, prior to such time, Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders do not accept such amendment. Such LIBOR Successor Rate shall be applied in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible for the Administrative Agent, such LIBOR Successor Rate shall be applied in a manner as otherwise reasonably determined by the Administrative Agent.

If no LIBOR Successor Rate has been determined and the circumstances under clause (i) above exist or the Scheduled Unavailability Date has occurred (as applicable), the Administrative Agent will promptly so notify each Borrower and each Lender. Thereafter, (x) the obligation of the Lenders to make or maintain Euro-Dollar Loans shall be suspended (to the extent of the affected Euro-Dollar Loans or Interest Periods only), and (y) the London Interbank Offered Rate component shall no longer be utilized in determining the Base Rate. Upon receipt of such notice,

any Borrower may revoke any pending request for a Borrowing of, conversion to, or continuation of Euro-Dollar Loans (to the extent of the affected Euro-Dollar Loans or Interest Periods) or, failing that, will be deemed to have converted such request into a Base Rate Borrowing (subject to the foregoing clause (y)) in the amount specified therein.

Notwithstanding anything else herein, any definition of LIBOR Successor Rate shall provide that in no event shall such LIBOR Successor Rate be less than 0% for purposes of this Agreement.

For purposes hereof, “LIBOR Successor Rate Conforming Changes” means, with respect to any proposed LIBOR Successor Rate, any conforming changes to the definition of Base Rate, Interest Period, timing and frequency of determining rates and making payments of interest and other administrative matters as may be appropriate, determined by the Administrative Agent with the consent of the Borrower, to reflect the adoption of such LIBOR Successor Rate and to permit the administration thereof by the Administrative Agent in a manner substantially consistent with market practice (or, if the Administrative Agent determines that adoption of any portion of such market practice is not administratively feasible or that no market practice for the administration of such LIBOR Successor Rate exists, in such other manner of administration as the Administrative Agent determines is reasonably necessary in connection with the administration of this Agreement).”

(b)    Section 9.05 is amended by replacing it in its entirety with the following:

“Section 9.05 Amendments and Waivers. Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of the Administrative Agent, Swingline Lender or any Issuing Lenders are affected thereby, by the Administrative Agent, Swingline Lender or such Issuing Lender, as relevant); provided, that the Administrative Agent and the Borrower may, without the consent of any Lender, enter into amendments or modifications to this Agreement or any of the other Loan Documents or to enter into additional Loan Documents as the Administrative Agent reasonably deems appropriate in order to implement any LIBOR Successor Rate or otherwise effectuate the terms of Section 2.14(b) in accordance with the terms of Section 2.14(b); provided, further, that no such amendment or waiver shall, (a) unless signed by each Lender adversely affected thereby, (i) extend or increase the Commitment of any Lender or subject any Lender to any additional obligation (it being understood that waivers or modifications of conditions precedent, covenants, Defaults or of mandatory reductions in the Commitments shall not constitute an increase of the Commitment of any Lender, and that an increase in the available portion of any Commitment of any Lender as in effect at any time shall not constitute an increase in such Commitment), (ii) reduce the principal of or rate of interest on any Loan (except in connection with a waiver of applicability of any post-default increase in interest rates) or the amount to be reimbursed in respect of any Letter of Credit or any interest thereon or any fees hereunder, (iii) postpone the date fixed for any payment of interest on any Loan or the amount to be reimbursed in respect of any Letter of Credit or any interest thereon or any fees hereunder or for any scheduled reduction or termination of any Commitment or (except as expressly provided in Article III) expiration date of any Letter of

Credit, (iv) postpone or change the date fixed for any scheduled payment of principal of any Loan, (v) change any provision hereof in a manner that would alter the pro rata funding of Loans required by Section 2.04(b), the pro rata sharing of payments required by Sections 2.09(b), 2.11(a) or 9.04 or the pro rata reduction of Commitments required by Section 2.08(a) or (vi) change the currency in which Loans are to be made, Letters of Credit are to be issued or payment under the Loan Documents is to be made, or add additional borrowers or (b) unless signed by each Lender, change the definition of Required Lender or this Section 9.05 or Section 9.06(a).”

“LIBOR Successor Rate” shall have the meaning specified in Section 2.14(b).

“LIBOR Successor Rate Conforming Changes” shall have the meaning specified in Section 2.14(b).
