Press Release regarding earthport update dated 18 January 2005


                                                                 18 January 2005

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

                         ("Baltimore" or "the Company")

                                earthport update

Update regarding earthport litigation
earthport plc ("earthport") has failed to comply with a High Court Order dated
21 December 2004, to which it consented, to pay Baltimore agreed costs of GBP750
by 14 January 2005. earthport has also failed to provide further information
about its claim by 14 January 2005, as required under the High Court Order of 21
December 2004.

Since earthport is in breach of the High Court Order, Baltimore applied
yesterday to the High Court for a further order that, unless earthport provides
to Baltimore further information about its claim by 28 January 2005 and pays
GBP750 costs plus interest within 24 hours, earthport's claim will be struck
out.

Herbert Smith continues to consider that, on current information, the claim
against Baltimore is without merit. Furthermore, if costs and interest (if
awarded) remain unpaid, the Company expects to apply for a winding up order.

Update regarding possible offer for Baltimore, by earthport
Baltimore notes that no offer for the Company has yet been made by earthport,
despite its announcement made on 20 December 2004 which stated "earthport
confirms that it is considering a possible offer for Baltimore. earthport
intends to approach the board of Baltimore in the next few days with its
proposal and to seek a recommendation..."

Baltimore also notes that earthport's accounts for year ended 30 June 2004
announced on 31 December 2004 were qualified and indicate a negative net worth
in excess of GBP6 million, and an immediate need for GBP1.378 million to meet
creditors' demands.

In the RNS release of its final results for the period ended 30 June 2004, dated
31 December 2004, earthport announced that "The company has an immediate
requirement to raise further funds" and "The company has also entered into an
investment agreement, subject to the completion of due diligence and agreement
of final terms by 10 January 2005, for the investment of up to GBP2.4m in three
monthly tranches of up to GBP0.8 million, through the issue of convertible loan
notes by March 2005". Baltimore notes that earthport has not made any further
announcement to date about the financial position and potential fundraising.
