Note 1: Bids may be made on either a competitive or a non-competitive basis.
Details of the bidding procedures are set out in the prospectus and in the
Information Memorandum (as amended). Gilt-edged Market Makers may bid by
telephone to the DMO not later than 10.30 am on Thursday, 15 March 2007.

Note 2: The terms of the DMO's financing remit set by HM Treasury state that the
coupon for a new gilt will be set as far as possible to price it close to par at
the time of issue. For new conventional gilts, coupons are set in multiples of
¼%. On the basis of current yields, the multiple of ¼% that would most precisely
meet this criterion is 5%. However, setting the coupon at this level would
result in two bonds maturing in the same year with the same coupon (5% Treasury
Stock 2012 matures on 7 March 2012). In order to avoid any potential market
confusion between the two bonds, the DMO has decided to set the coupon at the
multiple of ¼% that is next closest to prevailing market yields, i.e. 5¼%. The
DMO will be gathering views in the forthcoming year regarding options for
handling any similar situation in the future.

Note 3. The Gilt may not be stripped and reconstituted until so specified in a
notice issued by the DMO.

Note 4: Holders may elect to have United Kingdom income tax deducted from
interest payments, should they so wish, on application to the Registrar,
Computershare Investor Services PLC.
