If the Over-Allotment Option is exercised in full, the total gross proceeds of the Common Shares offering will be $69,161,000. In consideration for the services to be rendered by the Underwriters under the Offering, the Underwriters will receive a cash commission equal to 5% of the gross proceeds raised under the Offering (inclusive of the Over-Allotment Option).

In connection with the Offering, ProMetic will file a preliminary short form prospectus (the "Prospectus") in all Canadian provinces on or about May 10, 2016.

(2) the scale-up of PBI-4050 follow-on drug candidates and their advancement into clinical stages (3) the advancement of new clinical indications for plasminogen including wound healing (4) the expansion of clinical uses and proprietary positions on some plasma-derived orphan drugs, (5) the expansion of manufacturing capabilities related to the plasma derived therapeutics. These initiatives, as well as providing additional working capital will allow the Corporation to continue to exercise greater control and ownership over its technology platforms, therefore providing an opportunity to retain a greater portion of the associated value for its shareholders.

Closing of the Offering is subject to certain conditions including, but not limited to, receipt of all necessary regulatory and stock exchange approvals, including the receipt of listing approval by the Toronto Stock Exchange ("TSX") for the Common Shares.
