DISCLAIMER

This announcement must be read in conjunction with the Tender Offer Memorandum. The Tender Offer Memorandum contains important information which must be read carefully before any decision is made with respect to the Offers described in the announcement. If any Holder is in any doubt as to the action it should take, it is recommended to seek its own legal, tax and financial advice, including as to any tax consequences, from its stockbroker, bank manager, counsel, accountant or other independent financial adviser. Any Holder whose Notes are held on its behalf by a broker, dealer, bank, custodian, trust company or other nominee must contact such entity if it wishes to offer to tender such Notes pursuant to the Offers.

This announcement is neither an offer to purchase nor the solicitation of an offer to sell any of the securities described herein, and neither this announcement nor the Tender Offer Memorandum constitutes an offer or an invitation to participate in an offer in the United States or in any jurisdiction in which, or to any person to or from whom, it is unlawful to make such offer or invitation or for there to be such participation under applicable securities laws.

Holders must make their own decision as to whether to offer to tender any of their Notes, and, if so, the principal amount of such Notes to tender.

The EMTN Issuer has not filed this announcement or the Tender Offer Memorandum with, and they have not been reviewed by, any federal or state securities commission or regulatory authority of any country. No authority has passed upon the accuracy or adequacy of the Offers, and it is unlawful and may be a criminal offence to make any representation to the contrary.
