Press Release regarding Response to Acquisitor dated 19 April 2004



                           Baltimore Technologies Plc

                 Response to Acquisitor Holdings (Bermuda) Ltd

    Acquisitor fail to present a single proposal of how to build a business

London, UK - 19 April 2004. David Weaver, Chief Executive of Baltimore
Technologies Plc (London: BLM) "Baltimore", issued the following response to
Acquisitor Holdings (Bermuda) Ltd "Acquisitor", which issued an open letter to
Baltimore's shareholders today.

"Today's announcement demonstrates just how little Acquisitor really have to
offer shareholders. They continue to focus on the past, make inaccurate
statements and choose to ignore that the ongoing Baltimore Board of seven
includes six new appointments. Crucially, they fail to present a single proposal
of how to build a business. Once again, they have also not given any detail on
the so-called value they claim to have created in the past.

In contrast, the new Baltimore Board has a world-class energy team with over 10
decades of collective experience in the sector. I personally have over 38 years
of experience, including building businesses for some of the world's leading
energy companies like BP plc. We have a real plan and the experience to
implement it swiftly and effectively.

We urge Baltimore shareholders to reject Acquisitor's opportunistic approach, by
supporting the new Baltimore board at the forthcoming EGM."
