(b) Pursuant to clause 37.1 (Required consents) of the Agreement, the Majority Lenders have consented to the amendments and the waiver to the terms of the Agreement contemplated by this letter. Accordingly, we are authorised to execute this letter on behalf of the Finance Parties.

(c) Under a letter dated 26 July 2007, the Company has requested that the Majority Lenders:

(i) waive the requirement under Clause 6(a) (Extension option) of the Agreement that the Borrower provides any Extension Request before the first anniversary of the Agreement (the First Extension Request) no later than 60 days before that anniversary and accept, in lieu of a valid Extension Request under that Clause, the letter dated 25 July 2007 from the Company to the Facility Agent (the Request Letter) as constituting a valid Extension Request (notwithstanding the date of the Request Letter); and

(ii) in relation to the First Extension Request only, consent to amend Clause 6(f) and (g) (Extension option) of the Agreement so that any reference to “the date falling 30 days from the date of the relevant Extension Request” will be read as a reference to “10 August 2007”.

3. Waiver of certain obligations

The Majority Lenders have agreed to waive the requirements under Clause 6(a) (Extension option) of the Agreement referred to in paragraph 1(c)(i) above. Accordingly, we are authorised to confirm that the requirements under Clause 6(a) (Extension option) of the Agreement referred to in paragraph 1(c)(i) above are waived with effect from the date on which the Obligors and the Security Providers countersign this letter.

4. Amendments

(a) Subject to subparagraph (b) below, the Agreement will be amended on and from the Effective Date in accordance with subparagraph (c) below.

(b) The Agreement will not be amended by this letter unless the Facility Agent notifies the Company and the Lenders that it has received a copy of this letter countersigned by the Obligors and Security Providers. The Facility Agent must give this notification as soon as reasonably practicable.

In each of paragraphs (f) and (g) of clause 6 (Extension option), the following wording will be added before “on or before the date falling 30 days from the date of the relevant Extension Request”:
