YM BioSciences Reports Divestiture of Nimotuzumab Assets by CIMYM

December 3, 2012

MISSISSAUGA, ON, Dec. 3, 2012 /PRNewswire/ – YM BioSciences Inc. (NYSE MKT: YMI, TSX: YM) today reported that CIMYM BioSciences Inc. has sold its assets relating
to nimotuzumab to InnoKeys PTE Ltd., a company based in Singapore, for
undisclosed consideration including an immediate US$2 million payment.
CIMYM was a joint venture subsidiary 80% owned by YM BioSciences and
20% owned by CIMAB S.A. (representing Centro de Inmunología Molecular,
Cuba). CIMAB S.A. has reported it has partnered with InnoKeys and they
have incorporated a joint venture called InnoMab PTE Ltd, which is now
the owner of the assets related to nimotuzumab.

“This agreement allows YM to focus entirely on our lead drug, CYT387,
and our pre-clinical programs,” said Dr. Nick Glover, President and CEO
of YM BioSciences. “In turn, InnoMab has been formed to focus on the
continued development and commercialization of nimotuzumab and operate
directly with CIMYM’s former sub-licensees to further build the
nimotuzumab franchise and leverage its value.”
