connection with the exercise of conversion rights in respect of £145,000
nominal value of convertible loan stock by three directors. Stuart Silcock,
Andrew Michuda and Arif Karimjee have converted their holdings of the loan
stock comprising £100,000, £28,000 and £17,000 respectively, and resulting in
the issue of 833,333, 233,333 and 141,667 new ordinary shares in each case.

convertible loan stock, and to crystallise associated tax liabilities prior to

Arif Karimjee have sold at 26p per ordinary share, 96,000, 120,000 and 54,000
ordinary shares respectively, representing a proportion of their newly acquired
ordinary shares as described above.
