Press Release regarding Earthport Claim dated 05 July 2004


                           Baltimore Technologies plc

                            Claim from Earthport plc

London, UK 2 July 2004; The Board of Baltimore Technologies plc announces that
it has today received from solicitors acting for Earthport plc details of
potential claims against Baltimore.

These alleged claims arose out of agreements entered into between Baltimore and
Earthport in March 2001. Earthport has not commenced legal proceedings in
respect of these claims. Its claims are for the return of its payment of GBP4.5
million to Baltimore under these agreements, with interest, plus additional
damages which Earthport is currently assessing but which it claims to be
substantial.

The Board of Baltimore will urgently look into this matter but knows of no
foundation for these alleged claims.

                                     ENDS
