Dear Madam

REQUEST FOR TRADING HALT

We request a trading halt for Biotron Limited and provide the following information as set out in Listing Rule 17.1:

• Following the close of the Company's Share Purchase Plan ('SPP') which was managed by Bell Potter Securities, negotiations to complete a placement of SPP shortfall shares are being finalised.

• We request that the trading halt lasts for two business days, or until the Company is able to make an announcement before the end of the two business days.

• The announcement is expected to end the trading halt.

• We are not aware of any reason why the trading halt should not be granted.

• We have no further information necessary to inform the market about the trading halt.

Should you require any further information, do not hesitate to contact me.

Yours sincerely
