“(c) Any Lender may at any time assign to one or more banks, other institutions or other entities that regularly make, purchase or invest in bank loans (each an “Assignee”) all, or a proportionate part of all, of its Commitment of any Class or its Loans and Letter of Credit Liabilities of any Class and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement substantially in the form of Exhibit D hereto signed by such Assignee and such transferor Lender, with (and subject to) the subscribed consent of the Borrower (which shall not be unreasonably withheld or unreasonably delayed) and the Administrative Agent (and, in the case of a Revolving Commitment, the Issuing Banks and the Swing Loan Lender); provided that (i) after giving effect to any proposed assignment, (A) the Credit Exposure of the transferor Lender (or in the case of a transferor Lender that is a fund, the aggregate Credit Exposure of such Lender and its Related Funds) shall be equal to (x) $0 or at least $5,000,000 if the transferor is a Revolving Lender and (y) $0 or at least $1,000,000 if the transferor is a Term Lender and (B) the amount of the Credit Exposure of the transferor Lender subject to such assignment shall be at least equal to (x) $5,000,000 if the Assignee is a Revolving Lender or (y) $1,000,000, if the Assignee is a Term Lender, unless in either case the proposed Assignee is an affiliate of the transferor Lender, a Related Fund of any Lender or was a Lender immediately before such assignment, and (ii) if an Event of Default shall have occurred and be continuing, no such consent of the Borrower shall be required. When such instrument has been signed and delivered by the parties thereto and recorded as provided in Section 2.14, and such Assignee has paid to such transferor Lender the purchase price agreed between them, such Assignee shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender with a Commitment and/or Loans as set forth in such instrument of assumption,

2

and the transferor Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection, the transferor Lender, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if required, a new Note is issued to the Assignee. In connection with any such assignment (other than an assignment to which any Agent or any affiliate of any Agent is a party), the transferor Lender shall pay to the Administrative Agent an administrative fee for processing such assignment in the amount of $3,500; provided that only one such fee shall be due in respect of a simultaneous assignment to more than one Related Fund. If the Assignee is not incorporated under the laws of the United States or a State thereof, it shall deliver to the Borrower and the Administrative Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 8.04(d).”

SECTION 4. Representations of Borrower. The Borrower represents and warrants that (i) the representations and warranties of the Borrower set forth in Article 4 of the Credit Agreement will be true in all material respects on and as of the Amendment Effective Date (as defined below) with the same effect as though made on and as of such date, except to the extent such representations and warranties expressly relate to an earlier date and (ii) no Default will have occurred and be continuing on such date.

SECTION 5. Governing Law. This Amendment shall be governed by and construed in accordance with the laws of the State of New York.

SECTION 6. Counterparts. This Amendment may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

SECTION 7. Effectiveness. This Amendment shall become effective on the first date when the following conditions are met (the “Amendment Effective Date”):

(a) the Administrative Agent shall have received counterparts hereof signed by each of the Required Lenders and the Borrower (or, in the case of any party as to which an executed counterpart shall not have been received, the Administrative Agent shall have received in form satisfactory to it facsimile or other written confirmation from such party of execution of a counterpart hereof by such party); and

(b) the Administrative Agent and the Arrangers shall have received payment of all amendment fees, other costs, fees and expenses (including, without limitation, reasonable legal fees and expenses for which invoices shall have been submitted to the Borrower) and other compensation payable to any of the foregoing on or prior to the Amendment Effective Date in connection with the Loan Documents.

3

Promptly after the Amendment Effective Date occurs, the Administrative Agent shall notify the Borrower, the other Agents and the Lenders thereof, and such notice shall be conclusive and binding on all parties hereto.

4

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly executed as of the date first above written.
