Dear Sirs

RE: Recent Private Placement of Shares (ASX:MDM)

The Directors are pleased to announce that a Private Placement of Fully Paid Ordinary Shares under Listing Rule 7.1 has now been completed.

A total of 13,492,000 fully paid ordinary (FPO) shares will be issued. A total of \$850,000 was raised at \$0.063 per share in the placement ( being 'at market' for the preceding week of trading).

The funds will be used as working capital, to strengthen the Company's position as a leader in medical diagnostic monitoring in the Australasian market - particularly for ECG and blood pressure monitoring.

The Directors anticipate that no further private placements for working capital will be necessary, as significant sales of its products and services are expected as previously announced in March. Medical Monitors' products already have FDA, TGA and CE registration that allow for sales to be made in the relevant markets.

Medical Monitors Limited is an Australian health service and medical technology company that enables people to simply and effectively monitor specific cardiovascular conditions through unique technology. Medical Monitors is the sole provider of an Australia-wide monitoring service that is attracting strong interest from major healthcare players internationally.
