On 7 November 2003, Microgen plc ('Microgen') released an announcement
declaring that the Offer made by Close Brothers Corporate Finance Limited on
behalf of Microgen for M.M.T. Computing Public Limited Company (M.M.T.) was
wholly unconditional.

The Board of Microgen announces that as at 3.00 p.m. on 13 November 2003 valid
acceptances of the Offer had been received in respect of a total of 10,970,672
M.M.T. Shares, representing approximately 90.1 per cent. of the existing issued
ordinary share capital of M.M.T..

As valid acceptances of the Offer have been received in respect of more than
nine-tenths in value of M.M.T.'s Shares to which the Offer relates, Microgen
intends to apply the provisions of sections 428-430F of the Companies Act 1985
to acquire compulsorily all outstanding M.M.T. Shares on the terms of the
Offer. Accordingly, Microgen will be posting shortly formal notices under
section 429 of the Companies Act 1985 to M.M.T. Shareholders who have not yet
accepted the Offer.

The Offer will remain open until further notice. As previously announced, the
Mix and Match Facility closed at 3.00 p.m. on 10 November 2003.

The expressions in this announcement, unless the context otherwise requires,
bear the same meaning as in the Offer Document dated 13 October 2003.
