2009 Chairman’ Annual Meeting address

28 August 2009: BrainZ Instruments Limited (ASX:BZI) (“BrainZ”)

It has been a challenging time for BrainZ.

At the start of the financial year ending March 2009 we were faced with poor sales growth and ongoing cash burn as well as long term liability commitments related to product warranties. It was pleasing to close a sale of the business assets to Natus Medical in late 2008, especially given the financial situation internationally. As part of this process Natus took over the obligations related to product warranties, including those arising from our distribution agreement with GE. The technology transfer to Natus Medical has been effected satisfactorily to date.

Since late last year the BrainZ operation has been winding down, with all staff other than the board of directors and CFO leaving the Company in early 2009. The group companies in the USA and UK are now in the final stages of wind-up. The board of directors of BrainZ continues to explore possibilities regarding the Company shell.

The Board is considering a return of capital to shareholders towards the end of 2009 when the company has been fully wound down. This may require the Company to be liquidated. Depending on the legal means of effecting any distribution, shareholder approval may also be required. Based on the information currently available to the Board it remains of the opinion that the cash to be returned to shareholders is likely to be approximately NZ$0.03-0.04 per share.

At end June 2009 the BrainZ cash balance was NZ$2.766 million, with 60 million shares on issue.

Monthly cash flow announcements will continue to be made via the ASX.
