Company Announcements Office Australian Stock Exchange Limited Exchange Centre 20 Bridge Street SYDNEY NSW 2001

Dear Sir/Madam

APPENDIX 3B – SHARE AND OPTION ISSUE ADVICE

I advise that Imdex Limited has recently issued 4,875,000 options to key staff. The options have a five year life and an exercise price of $3.00. They are exercisable one year after the date of issue in onethird lots each year thereafter and lapse if the employee leaves the Company.

The issue of these options is seen as a future incentive to new Group employees and to assist in securing the future involvement and commitment of these key people.

No director has participated in this issue.

The Company has also recently issued 405,334 ordinary shares in Imdex Limited as a result of the exercise of Staff Options.

Also, in accordance with the Staff Option Plan rules, the following staff options have been cancelled due to the resignation of the relevant employees.

• 15,000 Staff Options with an exercise price of 35 cents per option

• • 35,000 Staff Options with an exercise price of $1.00 per option

• 50,000 Staff Options with an exercise price of $1.80 per option

The requisite Appendix 3B advice is attached.

Yours faithfully

Imdex Limited
