  Lorus Therapeutics To Focus Exclusively On Drug Development
  TORONTO, ONTARIO--  
  -- Announces divestiture of manufacturing facility-- 
  Lorus Therapeutics Inc. ("Lorus") today announced that it has  signed an agreement with Prometic Life Sciences Inc. ("Prometic"), a Canadian pharmaceutical company, regarding the divestiture of  its manufacturing facility in Scarborough, Ontario.  The Company  announced that, as a result of this transaction, it will be  relocating to Markham, Ontario on December 18, 1998. The specific  terms of the transaction were not disclosed. 
  Lorus presently maintains a 22,000 sq.ft. facility which houses a  5,000 sq.ft. cGMP manufacturing plant.  "The agreement between  Lorus and Prometic involves the transfer of the facility including 40 percent of our current staff, and it includes the acquisition  of  certain assets by Prometic in return for cash," said Philippe  G. Lacaille, President and Chief Executive Officer of Lorus  Therapeutics.  "Our decision to  move from the facility and to  transfer the manufacturing of our products to outside  organizations is based on two factors.  First, the large scale  manufacturing of Virulizin(r) will more than likely be undertaken  by a strategic corporate partner at the time a licensing deal is  signed, and second, the manufacturing of our NC analogs will be  accomplished more economically through a third party manufacturer. The agreement with Prometic is good for Lorus because it decreases our monthly cash expenditures and it allows us to focus  exclusively on drug development."
