(a)           all representations and warranties of such Transaction Party contained in the Master Transaction Agreement and any other Transaction Document are true and correct in all material respects with the same effect as if such representations and warranties had been made on the Amendment Date (it being understood and agreed that any representation which by its terms is made as of a specified date shall be required to be true and correct only as of such specified date);

Section 10.             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 one and the same agreement.  Delivery of an executed counterpart of a signature page to this Amendment by facsimile shall be as effective as delivery of a manually executed counterpart of this Amendment.

Section 11.             Headings.  The headings set forth in this Amendment are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

Section 12.             Severability.  In case any provision in or obligation under this Amendment shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

Section 13.             Legal Fees; No Novation Fees.  Counterparty and the Guarantors shall pay promptly upon request by the Hedge Provider all legal fees incurred by the Hedge Provider in connection with this Amendment.  The Hedge Provider agrees that, except as otherwise set forth herein, no additional fees shall be due from the Counterparty or the Guarantors in respect of the novation of the Hedging Facility or any similar transaction related to Hedging Facility entered into by the Counterparty other than amounts representing costs and expenses actually and reasonably incurred by the Hedge Provider and its outside counsel in connection therewith and any amount payable in respect of the value of the Hedging Facility.

Section 14.             No Novation.  The parties intend that the execution and delivery of this Amendment shall not constitute a novation of either Master Transaction Agreement or any Hedging Transactions thereunder.
