THE OFFER PERIOD WILL COMMENCE ON 23 JULY 2007 AND END ON 5 OCTOBER 2007 AT 3PM AMSTERDAM TIME, UNLESS EXTENDED

With reference to the press releases of 29 May 2007, 22 June 2007, 5 July 2007, 16 July 2007 and 20 July 2007, RFS Holdings B.V. (“RFS Holdings”), a company formed by Fortis N.V. and Fortis SA/NV (“Fortis”), The Royal Bank of Scotland Group plc (“RBS”) and Banco Santander Central Hispano, S.A. (“Santander”) hereby announces that RFS Holdings is offering to acquire all of the issued and outstanding ordinary shares with a nominal value of €0.56 per share (the “ABN AMRO Ordinary Shares”) in the share capital of ABN AMRO Holding N.V. (“ABN AMRO”) (the “Offer”).

The Offer

Under the terms of the Offer, holders of ABN AMRO Ordinary Shares (“ABN AMRO Shareholders”) will receive for each ABN AMRO Ordinary Share validly tendered and not properly withdrawn:

 

(i) €35.60 in cash; and

 

(ii) 0.296 newly issued ordinary shares with a nominal value of £0.25 per share of RBS (“New RBS Ordinary Shares”), (collectively the “Offer Consideration”).

The Offer is made on the terms and subject to the conditions and restrictions contained in the offer document for the Offer dated 20 July 2007 (the “Offer Document”), including the listing particulars of 20 July 2007 in respect of the New RBS Ordinary Shares (the “Listing Particulars”) (together, the “Offer Documents”) and the other documents incorporated by reference in the Offer Documents. For the purposes of the Dutch offer rules, the Offer extends to the ABN AMRO ADSs, provided that the holders of ABN AMRO ADSs are referred to the U.S. Prospectus (as defined below), which is incorporated by reference into the Offer Document and can be obtained from the global information agent.

Offer Documents

The Offer Documents are available to ABN AMRO Shareholders from the date hereof and as further described in the paragraph headed “Further Information; Obtaining Offer Documents”. ABN AMRO Shareholders should refer to the Offer Documents, for all of the terms of and conditions and restrictions applicable to the Offer.

Offer period

The initial offer period under the Offer will commence on 23 July 2007 and end on 5 October 2007 at 3pm, Amsterdam time, unless the initial offer period is extended in accordance with applicable offer rules.


RFS Holdings may extend the period of time for which the Offer is open until all conditions to the Offer have been satisfied or, to the extent legally permitted, waived. Extension of the offer period may occur one or more times. ABN AMRO Ordinary Shares tendered into the Offer may be withdrawn at any time prior to the end of the offer period (including any extensions thereof). Once the offer period has ended, holders of ABN AMRO Ordinary Shares will not be able to withdraw any tendered ABN AMRO Ordinary Shares. No withdrawal rights will apply to ABN AMRO Ordinary Shares tendered during a subsequent offering period (na-aanmeldingstermijn), if one is provided.

Procedures for tendering ABN AMRO Ordinary Shares

ABN AMRO Shareholders who hold their shares through a financial intermediary that is an admitted institution should make their acceptance of the Offer known to the Dutch exchange agent, Fortis Bank (Nederland) N.V., through their financial intermediary before the end of the offer period. The financial intermediary may set an earlier deadline for receipt of acceptances in order to permit the financial intermediary to communicate the acceptances to the Dutch exchange agent in a timely manner. ABN AMRO Shareholders who wish to tender their shares should contact the financial intermediary through which they hold their ABN AMRO Ordinary Shares to obtain information on the deadline by which they must make their acceptance of the Offer known to their financial intermediary.

Holders of ABN AMRO Ordinary Shares in registered form (outside Euroclear Nederland) can obtain an application form from the Dutch exchange agent to make their acceptance of the Offer known. The application form should be completed, signed and returned to:

Fortis Bank

Settlements Dept. A08.01.01

P.O. Box 243

1000 AE Amsterdam

The Netherlands

so as to reach the Dutch exchange agent before the end of the offer period. The acceptance forms will serve as a deed of transfer with respect to the tendered shares.

Holders of ABN AMRO Ordinary Shares in bearer form who do not hold their shares through admitted institutions can contact the Dutch exchange agent for information on how to tender their shares.

Declaring the Offer unconditional; Settlement

The Offer is subject to the offer conditions set out in paragraph 8 of Part IX of the Offer Document. RFS Holdings will only declare the Offer unconditional if the offer conditions, including the condition that the ABN AMRO Ordinary Shares tendered in the Offer and the U.S. Offer (as defined below), on a combined basis, or which are otherwise held by RFS Holdings, represent at least 80% of the ABN AMRO Ordinary Shares on a fully diluted basis, are satisfied or, to the extent legally permissible, waived. In such case RFS Holdings will, within five Euronext Amsterdam trading days after the end of the offer period, make a public announcement confirming that the Offer is declared unconditional. RFS Holdings reserves the right to waive any of the offer conditions to the extent legally permissible.

If the Offer is declared unconditional, New RBS Ordinary Shares and cash will be delivered to the tendering ABN AMRO Shareholders, on the terms and subject to the conditions and restrictions of the Offer, within five Euronext Amsterdam trading days.

The Offer Consideration may be reduced by an amount equal to the amount of any distribution by ABN AMRO to the holders of ABN AMRO Ordinary Shares in excess of an interim (cash or share) dividend of €0.55 per ABN AMRO Ordinary Share (before deduction of any applicable withholding taxes) in respect of the financial year 2007 as described in further detail in the Offer Document. In certain limited circumstances as described in Part IX paragraph 17 of the Offer Document (related to the manner in which the holder of ABN AMRO Ordinary Shares chooses to hold its New RBS Ordinary Shares) a 1.5% U.K. stamp duty reserve tax charge may arise in connection with the delivery of the New RBS Ordinary Shares, which the holder of ABN AMRO Ordinary Shares will be required to pay and which will be deducted from the cash consideration to which such holder is entitled.


If the Offer is declared unconditional, the New RBS Ordinary Shares will be listed on the London Stock Exchange and Euronext Amsterdam.

De-listing ABN AMRO Ordinary Shares

Upon completion of the Offer, RFS Holdings, Fortis, RBS and Santander intend, among other things and depending on the level of acceptance in the Offer, to seek to cause the delisting of ABN AMRO Ordinary Shares on Euronext Amsterdam. Other risks for non-tendering ABN AMRO Shareholders are set out in the Offer Documents.

Forward-Looking Statements

This announcement includes certain “forward-looking statements”. These statements are based on the current expectations of the Banks and are naturally subject to uncertainty and changes in certain circumstances. Forward-looking statements include any statements related to the benefits or synergies resulting from a transaction with ABN AMRO and, without limitation, statements typically containing words such as “intends”, “expects”, “anticipates”, “targets”, “plans”, “estimates” and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, the presence of a competitive offer for ABN AMRO, satisfaction of any conditions to the offer, including the receipt of required regulatory and anti-trust approvals, the successful completion of the offer or any subsequent compulsory acquisition procedure, the anticipated benefits of the offer (including anticipated synergies) not being realized, the separation and integration of ABN AMRO and its assets among the Banks and the integration of such businesses and assets by the Banks being materially delayed or more costly or difficult than expected, as well as additional factors, such as changes in economic conditions, changes in the regulatory environment, fluctuations in interest and exchange rates, the outcome of litigation and government actions. Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. None of the Banks undertake any obligation to update publicly or revise forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent legally required.

Any offer made in or into the United States will only be made by the Banks and/or RFS Holdings directly or by a dealer-manager that is registered with the SEC.
