Press Release regarding Appointment of Auditors dated 15 December 2004



                                                                15 DECEMBER 2004


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

                         ("Baltimore" or "the Company")

                            APPOINTMENT OF AUDITORS

Baltimore is pleased to announce the appointment of BDO Stoy Hayward LLP as
Auditors to the Company with immediate effect. KPMG were the Company's previous
Auditors and elected not to renew their appointment. KPMG previously notified
the Company that it had concerns around the Company's SEC obligations and its
ability to meet those obligations in an increasingly highly regulated
environment.

As previously announced, the Company intends to terminate its registration and
status as a reporting company under the US Securities Exchange Act of 1934 if
the Company's proposed share consolidation and termination of its ADR programme
has the effect of reducing the number of the Company's shareholders resident in
the United States to below 300.

Commenting on the appointment Chairman David Buchler said "KPMG has been the
Company's auditors for several years and we thank them for their past
endeavours. The new Board has decided to appoint a firm more appropriate to
Baltimore's current size and we look forward to working with BDO Stoy Hayward".
