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

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

accepted the Offer.

The Offer will remain open until further notice. As previously announced, the
