                          DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 relates to the Registration Statement (No.
333-90154) of ALSTOM (the "Registrant") which was filed with the Securities and
Exchange Commission on June 10, 2002 relating to Ordinary Shares to be sold
under the ALSTOM Stock Option Plan No. 3 July 24, 2001 and the ALSTOM Stock
Option Plan January 8, 2002 (the "Plans").


On June 14, 2005, the Registrant filed a Form 15 with the Securities and
Exchange Commission certifying that its Ordinary Shares are held of record by
fewer than 300 persons resident in the United States and requesting the
termination of its registration under Section 12(g) of the Securities Exchange
Act of 1934 and the suspension of its duty to file periodic reports under
Sections 13 and 15(d) of such Act. In addition, based on recent trading prices
of the Ordinary shares, all of the stock options granted under the Plans are
out-of-the-money. Accordingly, the Registrant hereby removes from registration
the Ordinary Shares registered but unsold under the Registration Statement.
