Letter to BGI Clients

Dear Client:

There is very little overlap between BGI and ABN AMRO’s asset management businesses, and we expect minimal disruption to our business while we complete any proposed transaction, and no fundamental change to BGI’s business model after any proposed combination. We expect no change to BGI’s existing investment strategies or investment philosophy. Clients should expect no change to their relationship or mandates with BGI. While this opportunity gets worked out, we have significant growth opportunities in front of us which we are pursuing relentlessly—we are not distracted by the discussions but remain focused on our clients, our performance and mission.

Future SEC Filings and this Filing: Important Information

In connection with the proposed business combination transaction between Barclays PLC (“Barclays”) and ABN AMRO Holding N.V. (“ABN AMRO”), Barclays expects it will file with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form F-4, which will constitute a prospectus, as well as a Tender Offer Statement on Schedule TO and other relevant materials. In addition, ABN AMRO expects that it will file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 and other relevant materials. Such documents, however, are not currently available. YOU ARE URGED TO READ ANY DOCUMENTS REGARDING THE POTENTIAL TRANSACTION IF AND WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION. You will be able to obtain a free copy of such filings without charge, at the SEC’s website (http://www.sec.gov) once such documents are filed with the SEC. Copies of such documents may also be obtained from Barclays and ABN AMRO, without charge, once they are filed with the SEC.

This filing shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale 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. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended.

Forward-Looking Statements

This document contains certain forward-looking statements within the meaning of Section 21E of the US Securities Exchange Act of 1934, as amended, and Section 27A of the US Securities Act of 1933, as amended, with respect to certain of ABN AMRO’s and Barclays plans and their current goals and expectations relating to their future financial condition and performance and which involve a number of risks and uncertainties. ABN AMRO and Barclays caution readers that no forward-looking statement is a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statements. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements sometimes use words such as ‘aim’, ‘anticipate’, ‘target’, ‘expect’, ‘estimate’, ‘intend’, ‘plan’, ‘goal’, ‘believe’, or other words of similar meaning. Examples of forward-looking statements include, among others, statements regarding the consummation of the business combination between ABN AMRO and Barclays within the expected timeframe and on the expected terms (if at all), the benefits of the business combination transaction involving ABN AMRO and Barclays, including the achievement of synergy targets, ABN AMRO’s and Barclays future financial position, income growth, impairment charges, business strategy, projected costs and estimates of capital expenditure and revenue benefits, projected levels of growth in the banking and financial markets, the combined group’s future financial and operating results, future financial position, projected costs and estimates of capital expenditures, and plans and objectives for future operations of ABN AMRO, Barclays and the combined group and other statements that are not historical fact. Additional risks and factors are identified in ABN AMRO and Barclays filings with the SEC including ABN AMRO and Barclays Annual Reports on Form 20-F for the fiscal year ending December 31, 2006, which are available on ABN AMRO’s website at www.abnamro.com and Barclays website at www.barclays.com respectively, and on the SEC’s website at www.sec.gov.

Any forward-looking statements made by or on behalf of ABN AMRO and Barclays speak only as of the date they are made. ABN AMRO and Barclays do not undertake to update forward-looking statements to reflect any changes in expectations with regard thereto or any changes in events, conditions or circumstances on which any such statement is based.
