ProMetic Provides Corporate Update

MONTREAL, QUEBEC--(Marketwire - April 18, 2011) - ProMetic Life Sciences Inc. (TSX:PLI) ("ProMetic") provides an update to shareholders.

"The recent transaction with Celgene which removes US$10 million of debt is a significant step towards improving the balance sheet", commented Mr. Pierre Laurin, ProMetic's President and CEO. He added, "Management is focused on closing other lucrative technology-related deals providing significant cash and recurring revenue to the Company. To achieve this amid lower than expected revenues, the Company needs to increase its cash level. The Company has recently closed a series of private placements with six long standing shareholders, which together total $2.75 million. This sum includes the $0.8 million already disclosed in the 2010 annual report as post balance sheet event."

Additional liquidity has been provided to the group with part of the previously disclosed $1.5 million raised in Newco being used in PLI on a temporary basis with the agreement of those who invested it. NewCo is currently attracting new business as well as fresh capital and additional announcements are forthcoming. Newco is expected to get additional funding in the second quarter of 2011.

Mr. Bruce Pritchard, ProMetic's Chief Financial Officer indicated, "These various sources of cash injection, when combined with the recently announced debt reduction of US$10 million and the postponement of the $4 million secured debt term to July 1, 2012, improves ProMetic's short-term liquidity and more importantly allows the Company greater opportunity to deliver on deals that will ultimately make it self-financing."

The series of equity investments by way of private placements (including the $0.8 million investment that was previously disclosed in ProMetic's 2010 Annual Report) brings total equity injections in ProMetic to $2.75 million since January 2011. These investments were done at an average approximate price of $0.16 per share for a total of 17,686,274 Common Shares of ProMetic and are subject to a four month hold period. No warrants were issued in relation to any said investments.
