(London time) on the applicable Quotation Day or (b) if no such rate is available, the rate reasonably determined by the Administrative Agent as the rate quoted to leading banks in the Singapore interbank market as of 12:00 P.M. (London time) on the Quotation Day for the offering of deposits in Singapore Dollars for a period comparable to the applicable Interest Period.”

2

“thereunder”, “thereof” or words of like import referring to the Existing Term Loan Agreement, shall mean and be a reference to the Existing Term Loan Agreement, as amended and modified by this Amendment.

(b) The Existing Term Loan Agreement, the Notes and each of the other Loan Documents, as specifically amended by this Amendment, are and shall continue to be in full force and effect and are hereby in all respects ratified and confirmed.

(d) This Amendment shall not extinguish the obligations for the payment of money outstanding under the Existing Term Loan Agreement. Nothing herein contained shall be construed as a substitution or novation of the obligations outstanding under the Existing Term Loan Agreement, which shall remain in full force and effect, except to any extent modified hereby or as provided in the exhibits hereto. Nothing implied in this Amendment or in any other document contemplated hereby shall be construed as a release or other discharge of any of the Loan Parties from the Loan Documents.

SECTION 5. Execution in Counterparts. This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement. Delivery of an executed counterpart of a signature page to this Amendment by facsimile shall be effective as delivery of a manually executed counterpart of this Amendment.
