Out of this package, superannuation payments will be made by Bionomics to cover its obligations under the Superannuation Guarantee (Administration) Act 1992.

The Board has also recognised your commitment over the last year and I am pleased to advise that a bonus of $31,500.00 cash equivalent will be paid, 50% in cash and 50% in Bionomics shares. The cash bonus amount will appear in your July pay and will be taxed accordingly.

In addition, the Board has awarded you a Long Term Bonus under the Employee Equity Plan of 1 million Options on the following terms;

● issue price of A$0.04 per Option (each Option convertible into one ordinary share);

● 500,00 Options vest at A$0.14c and 500,000 Options vest at A$0.24;

● all Options expire 5 years from the date of grant; and
