LAVAL, QUEBEC--(Marketwire - March 5, 2013) -ProMetic Life Sciences Inc. (TSX:PLI) ("ProMetic" or the "Corporation") announced today that it has finalized the repayment terms of $4 million worth of secured loans previously provided by some of its long term stakeholders ("Stakeholders"), effectively rescheduling the repayment of $4.0 million worth of secured debt from July 1, 2013 to July 1, 2014.

The Corporation also recognises the continued support of The Isle of Man's Department of Economic Development ("DED"), towards the growth of ProMetic's operations on the Isle of Man; DED has expanded its offer of financial support to ProMetic BioSciences Limited. The exact terms are still to be finalised, however DED agreed that the outstanding repayable working capital grant of approximately $550 000 would no longer be repayable in February 2013, but rather out of future capital grant contributions made by DED to ProMetic BioSciences Limited for qualifying projects.

The Corporation also recently amended the terms of its $800 000 loan agreement with Conister Bank which was originally due for payment in full in December 2012. The loan will now be repaid during the course of 2013, in 12 equal monthly instalments. The loan remains unsecured and continues to bear interest at a rate of 10% per annum.

"These loan extensions and working capital grant conversions clearly demonstrate, once again, the confidence shown by these investors and lenders in our ability to execute on our business plan. This significantly reduces pressure on our short term liquidity requirements and positively impacts our ability to continue to improve our balance sheet", said Mr. Bruce Pritchard, Chief Financial Officer of ProMetic.

As consideration for the above-mentioned $4 million worth of secured loans restructuring, the Stakeholders collectively received 1,043,476 shares in ProMetic's share capital at an approximate average share price of $0.46, representing 0.21% of ProMetic's outstanding shares or 0.19% on a fully diluted basis. The stakeholders also collectively received 754,715 warrants with a strike price of $0.53, which if exercised could, collectively with the above-mentioned shares, represent 0.16% of ProMetic's outstanding shares or 0.13% on a fully diluted basis. The Toronto Stock Exchange has given conditional approval to this issuance of shares and granting of warrants.
