DiaMedica Inc. Provides Update Regarding Sanomune Inc. Acquisition

WINNIPEG, MANITOBA--(Marketwire - April 20, 2010) - DiaMedica Inc. (TSX VENTURE: DMA) (“DiaMedica”), a biopharmaceutical company focused on a novel approach to treating diabetes, is pleased to provide an update with respect to its proposed acquisition (the “Acquisition”) of Sanomune Inc. (“Sanomune”), a privately held biopharmaceutical company focused on neurological conditions, and to announce details of its planned public offering of units (the “Offering”).

As previously disclosed, in order to avoid the cost and delay of holding a shareholders meeting to consider the Acquisition, DiaMedica made application to the Ontario Securities Commission (the “OSC”) for an order exempting DiaMedica from the requirements of Part 5.3(2) of Multilateral Instrument 61-101 (“MI 61-101"), and, in lieu of such requirements, to obtain the necessary disinterested minority approval for the Acquisition (the “Minority Approval”) by obtaining the written consent of shareholders. The requested order was issued by the OSC effective March 25, 2010.

DiaMedica is pleased to report that it has obtained written consents to the Acquisition from shareholders representing approximately 65% of the common shares of the company held by parties eligible to vote for approval of the transaction under Part 8 of MI 61-101. This is in excess of the simple majority requirement (i.e., 50%+1) set out in MI 61-101 for such Minority Approval.

Final acceptance of the Acquisition by the TSX Venture Exchange (the “TSX-V”) is conditional upon completion of an offering with proceeds of not less than $3,000,000 received from arm’s length investors.

The Company anticipates that the Sanomune Acquisition will be completed in May, 2010.

About DiaMedica and Sanomune

DiaMedica is a biopharmaceutical company developing treatments for diabetes, neurological and autoimmune diseases. Two of DiaMedica’s products, DM-71 and DM-99, have demonstrated human efficacy in lowering blood sugar levels in diabetics based on a novel nerve signaling mechanism.

Sanomune’s lead compound, SAN-61, for the treatment of Alzheimer’s disease, has demonstrated neural protection (protects brain cells) as well as the ability to trigger neural stem cell proliferation (generates new brain cells). The Ottawa Centre for Research and Innovation named both Sanomune and DiaMedica as a Top 10™ Canadian Life Sciences Company for 2009.

Following the completion of the Sanomune Acquisition, DiaMedica intends to expand into neurological and autoimmune diseases with a improved recombinant version of a protein that has demonstrated neural protection properties as well as neural stem cell proliferation properties. The protective and regenerative aspects of the protein are broadly applicable to numerous indications including Alzheimer’s and Huntington’s disease as well as type 1 diabetes. In addition, Sanomune is also developing a panel of monoclonal antibodies targeting diabetes, Alzheimer’s and leukemia based on the inhibition of GSK3B.
