13 August 2007 - Fortis, RBS and Santander Announcement

Fortis,   RBS  and  Santander  (the  "Banks")   announce  that  their  aggregate
shareholding  in ABN AMRO has been  increased to 3.25% of voting rights  through
market  purchases  on Friday 10 August  and Monday 13 August of a total of 40.76
million ABN AMRO ordinary shares at an average price of €33.81.

The Banks may make  further  purchases  of ABN AMRO shares  within the limits of
qualifying interest criteria determined by regulators.

--------------------------------------------------------------------------------

Important Information

This announcement is made pursuant to article 9b(1) of the Dutch Decree on the
Supervision of the Securities Trade 1995.

In  connection  with  the  offer  for ABN  AMRO,  RBS has  filed  with  the U.S.
Securities and Exchange Commission (the "SEC") a Registration  Statement on Form
F-4, which includes a preliminary version of the prospectus,  and the Banks have
filed with the SEC a Tender Offer  Statement  on Schedule TO and other  relevant
materials.  The Form F-4 has not yet become  effective.  INVESTORS  ARE URGED TO
READ  ANY  DOCUMENTS   REGARDING  THE  OFFER  BECAUSE  THEY  CONTAIN   IMPORTANT
INFORMATION.  Investors may obtain a copy of such documents  without charge,  at
the  SEC's  website  (http://www.sec.gov/).  Copies  of all  documents  filed in
connection with the offer may also be obtained from each Bank, without charge.

This communication  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. This press release is not an offer of securities for sale into the
United  States.  No offering of  securities  shall be made in the United  States
except  pursuant  to  registration  under the U.S.  Securities  Act of 1933,  as
amended, or an exemption therefrom.

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  synergy  statements  and,  without  limitation,  other
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,  whether  the Banks and ABN AMRO enter into any
definitive  agreement  with respect to the  potential  acquisition  of 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 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.
