Dear Sir.

Forthcoming release of restricted securities - Dr Mervyn Jacobson

I wish to inform the market that on 28 December 2002, 98,000,000 restricted fully paid ordinary shares (GTGAU) owned by interests associated with my family will be released from escrow. These restricted shares were originally issued in late 2000, as part of the vendor consideration relating to the acquisition of GeneType.

I wish to advise the market that to my knowledge, these associated interests have no current intention of selling all or part of these 98,000,000 shares, unless there is a takeover bid made to all shareholders of the Company on terms recommended by the Board.

Further, I advise that since late 2000, I have also personally purchased an additional 902,000 ordinary shares in GTG on market, as has already been reported in Appendix 3Y dated 11 November 2002.

Yours faithfully,

Dr Mervyn Jacobson Executive Chairman
