SemBioSys Genetics Inc. (TSX:SBS), specializing in the manufacture of high-value proteins and oils in plant seeds, today announced that effective March 25, 2010, Professor Maurice Moloney, Ph.D., the Company's Founder and Chief Scientific Officer has accepted a full-time position with the Biotechnology and Biological Sciences Research Council (BBSRC) and the Lawes Trust in the United Kingdom as the Chief Executive and Director of Rothamsted Research, the oldest and largest Institute in Europe in Agricultural Sciences.

"Dr. Moloney was the founder of SemBioSys and has made tremendous contributions to not only SemBioSys, including all of its foundation intellectual property, but to plant science as a whole. As one of a growing number of companies using plants to produce therapeutic proteins, SemBioSys is a leader in the production, extraction and purification of human proteins in plant seed, based on the discoveries of Dr. Moloney and his team and the intellectual property in-licenced from the University of Calgary," said James Szarko, Chief Executive Officer of SemBioSys. "His departure comes at a time when we have progressed to product formulation and scale-up at the clinical and preclinical stages of development for Biosimilar Human Insulin and Apo AIMilano, respectively. Through much of his efforts, we have a strong team that has successfully executed our research and development operations and we are now driving forward to secure partners for each of our lead programs."

"This position at BBSRC is a unique personal opportunity in UK and global agriculture to lead a team of over 400 scientists across a diverse range of agricultural science endeavours," said Dr. Moloney. "In a world of global climate change, bioenergy, concerns about food security and sustainability of agriculture, the developed countries must step to the fore to show leadership and innovation. As SemBioSys has proven its commitment to such technology through its recent Phase I/II insulin clinical trials, I felt that this was an appropriate time to start my next challenge and pass on our work to the expert team at SemBioSys. I do so with mixed emotions, but having worked closely with SemBioSys scientists, I am confident that SemBioSys will prove as successful in commercialization as it has in its scientific and technical innovation."

Dr. Moloney has worked closely with the SemBioSys team in developing a succession plan. He has agreed to SemBioSys, and negotiated with BBSRC the right, to remain engaged as a consultant and senior scientific advisor to SemBioSys to ensure efficient succession planning. Dr. Moloney will remain in his current position until his new start date of March 25th, 2010 at Rothamsted Research.
