(b) This letter is a Finance Document.

2.     Amendments

(a) With effect on and from the Effective Date, the Facility Letter will be amended by deleting 7 days in the Interest Periods clause of Schedule 2 and replacing it with 31 days.

(b) Subject to the terms of this letter, all other provisions of the Facility Letter remain unchanged and the Facility Letter will remain in full force and effect.

(c) The Facility Letter (including the Credit Terms and Conditions and the General Terms of Business) and this letter will be read and construed as one document.

(d) If the Effective Date has not occurred before the date that is 45 days after the date of this letter, then this letter shall immediately on such date be void and of no further legal force and effect.

3.     Representations

Each of the Borrowers confirms to the Bank on the date of this letter and on the Effective Date that the representations and warranties contained in the General Terms of Business:

(a) are true; and

(b) would also be true if references to the "Agreement" as referred to in the General Terms of Business are construed so as to include the Facility Letter as amended by this letter

in each case by reference to the facts and circumstances then existing. For the avoidance of doubt, such representations and warranties are, and shall be, thus confirmed by each of the Borrowers with respect to itself, notwithstanding any references in the drafting of such representations and warranties to "the Client" or "you".

4.    Fees, Costs and Expenses

(a) This letter and any non-contractual obligations arising out of or in connections with it are governed by English law.

(b) The Courts of England have exclusive jurisdiction to settle any dispute arising out of or in connection with this letter (including a dispute relating to any non-contractual obligation arising out of or in connection with this letter). The Bank and the Borrowers agree that the Courts of England are the most appropriate and convenient courts to settle any such disputes and accordingly none of them will argue to the contrary. This paragraph is for the benefit of the Bank only. As a result, the Bank shall not be prevented from taking proceedings relating to any such dispute in any other courts with jurisdiction. To the extent allowed by law, the Bank may take concurrent proceedings in any number of jurisdictions.
