Microbix and ImaRx Agree to Terminate Letter of Intent

    TORONTO, June 11 /CNW/ - Microbix Biosystems Inc. (TSX:MBX) and ImaRx
Therapeutics, Inc. (Nasdaq:   IMRX) have agreed to terminate the previously
announced letter of intent in which Microbix offered to acquire the urokinase
inventory and related assets from ImaRx for $17 million.

    Two recent events prompted this decision:

    -   ImaRx was notified by the FDA, after the LOI was signed, that
        additional testing would be required for approval of the urokinase
        stability testing program and release of labeled vials of urokinase.

    -   ImaRx subsequently informed Microbix that it intended to complete the
        additional urokinase stability testing and submit it to the FDA by
        August 2008 and that, as a result, ImaRx would not be in a position
        to begin sales of its labeled vials of urokinase with extended
        expiration dating until the Fall of 2008, assuming FDA approval. This
        was a materially different timeframe for product sales than
        contemplated in the LOI.

    Microbix had intended to spin off its own urokinase assets into a new
private company, Klarogen Biotherapeutics Inc., which would have purchased the
urokinase assets of ImaRx.
    Now that the LOI has been terminated, Microbix will continue to work with
a number of parties and ImaRx to determine the most logical and fundable path
forward with respect to the acquisition of the ImaRx urokinase assets.

    Microbix specializes in the development of biological technologies and
commercializing them through global partners. The Company has intellectual
property in large market biotherapeutic drugs, vaccine technologies and animal
reproduction technologies. Established in 1988, Microbix is headquartered in
