Dear Colleague

You may have seen in the media that the Boards of ABN AMRO say they are not currently in a position to recommend in favour of Barclays. I wanted to give you some context.

Those of you who follow our share price will know that last week was a pretty volatile week. Although, under our amended offer for ABN AMRO, approximately 37 per cent is now in cash, the majority of the payment to ABN AMRO shareholders for their shares will be in our shares. So the value of our offer is heavily dependent on where our shares are trading in any given time.

Given the falls right across the financial services sector last week, the value of our offer fared less well than the value of the Consortium offer (which is about 90 per cent in cash). It’s for this reason that the ABN AMRO Boards have withdrawn their recommendation. But do not read too much into this. It’s very clear from the announcement that they put out yesterday that they still favour Barclays bid over that of the Consortium. And I’m confident that if, which I hope and expect, our share price rises, then ABN AMRO’S recommendation will be reinstated.

SEC Filings and this Filing: Important Information

This document shall not constitute an offer to sell or buy or the solicitation of an offer to buy or sell any securities, nor shall there be any sale or purchase of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. The availability of Barclays offer to persons not resident in the United States, the Netherlands and the United Kingdom may be affected by the laws of the relevant jurisdictions. Such persons should inform themselves about and observe any applicable requirements.

In connection with the proposed business combination transaction between ABN AMRO Holding N.V. (“ABN AMRO”) and Barclays PLC (“Barclays”), Barclays has filed with the U.S. Securities and Exchange Commission (“SEC”) a Registration Statement on Form F-4 (“Form F-4”), which includes a preliminary version of the Barclays offer document/prospectus. The Form F-4 has not yet become effective. Barclays expects that it will also file with the SEC a Statement on Schedule TO and other relevant materials. In addition, ABN AMRO expects that it will file with the SEC a Recommendation Statement on Schedule 14D-9 and other relevant materials. Following the Form F-4 being declared effective by the SEC, Barclays intends to mail the final offer document/prospectus to holders of ABN AMRO ordinary shares located in the United States and Canada and to holders of ABN AMRO ADSs wherever located.

Such final documents, however, are not currently available. INVESTORS ARE URGED TO READ THE FINAL OFFER DOCUMENT/PROSPECTUS AND ANY DOCUMENTS REGARDING THE POTENTIAL TRANSACTION IF AND WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION.

Investors will be able to obtain a free copy of the Form F-4, the final offer document/prospectus and other filings without charge, at the SEC’s website (www.sec.gov) if and when such documents are filed with the SEC. Copies of such documents may also be obtained from ABN AMRO and Barclays without charge, if and when they are filed with the SEC.
