(‘‘RFS Holdings’’), a company formed by an affiliate of Fortis N.V. and Fortis SA/NV (Fortis N.V. and Fortis SA/NV together ‘‘Fortis’’), The Royal Bank of Scotland Group plc (‘‘RBS’’) and an affiliate of Banco Santander Central Hispano, S.A. (‘‘Santander’’), is offering to acquire all of the issued and outstanding ordinary shares, nominal value e0.56 per share (‘‘ABN AMRO Ordinary Shares’’), of ABN AMRO Holding N.V. (‘‘ABN AMRO’’), on the terms and conditions set out in this document (the ‘‘Offer’’). Under the terms of the Offer, holders of ABN AMRO Ordinary Shares will receive for each ABN AMRO Ordinary Share validly tendered and not properly withdrawn: • e35.60 in cash; and • 0.296 newly issued ordinary shares, nominal value £0.25 per share, of RBS (‘‘New RBS Ordinary Shares’’). For the purposes of the Dutch offer rules, the Offer extends to the ABN AMRO ADSs (as defined below), provided that, as further detailed below, the holders of ABN AMRO ADSs are referred to the U.S. Prospectus (as defined below), which is incorporated by reference into this document and can be obtained from the global information agent. As at 13 July 2007, the last trading day prior to the announcement made on 16 July 2007, the total value of the consideration being offered by RFS Holdings was e38.40 per ABN AMRO Ordinary Share, based on the closing price of 640p for the RBS Ordinary Shares on the London Stock Exchange (the ‘‘LSE’’) on that date and an exchange rate of e1.00 to £0.6777 as published in The Financial Times on 14 July 2007. The consideration set out above assumes the payment by ABN AMRO of an interim (cash or share) dividend in respect of 2007 in an amount not to exceed e0.55 per ABN AMRO Ordinary Share (before deduction of any applicable withholding taxes). If ABN AMRO declares an interim (cash or share) dividend in respect of 2007 in excess of e0.55 per ABN AMRO Ordinary Share (before deduction of any applicable withholding taxes) or any other (cash or share) dividend, distribution, share split or analogous transaction in respect of the ABN AMRO Ordinary Shares, and the record date for such (cash or share) dividend, distribution, share split or analogous transaction precedes the Settlement of the Offer, the consideration set out above may be reduced by an amount, in the case of an interim (cash or share) dividend in respect of 2007 in excess of e0.55 per ABN AMRO Ordinary Share, equal to such excess (before deduction of any applicable withholding taxes), or otherwise by the full amount of any other such dividend, distribution, share split or analogous transaction (before deduction of any applicable withholding taxes). If ABN AMRO declares an interim (cash or share) dividend in respect of 2007 of e0.55 or less per ABN AMRO Ordinary Share (before deduction of any applicable withholding taxes), and the record date for such dividend precedes the Settlement of the Offer, the consideration set out above will not be adjusted.
