Press Release regarding 'earthport update'  dated 02 February 2005






                                                                 2 FEBRUARY 2005

                           BALTIMORE TECHNOLOGIES PLC
                  (Ticker: Reuters BLM.L or Bloomberg: BLM LN)

                         ("Baltimore" or "the Company")

                                earthport update

The Board of Baltimore has noted earthport plc's ("earthport") decision not to
proceed with an offer for the Company. The Board is pleased that this unwelcome
distraction has been removed.

On Tuesday 1 February 2005, Baltimore secured a High Court order that, unless
earthport provides security for costs in the sum of GBP180,000 by 1 March 2005,
its claim will be struck out. The Company did not oppose earthport's application
to amend its Particulars of Claim but has reserved its right to challenge these
amendments at a later date, if so advised.

The High Court also ordered that earthport should pay the Company's costs
occasioned by both the Company's application for security for costs and
earthport's application for leave to amend the Particulars of Claim. The size of
the costs award will be determined at a later date, but the court ordered that
earthport must, by 1 March 2005, pay GBP15,000 on an interim basis.
