XOMA Announces Management Changes
BERKELEY, Calif., Aug 31, 2011 (GlobeNewswire via COMTEX) -- XOMA Ltd. announced today Steve Engle has chosen to resign from his positions as Chief Executive Officer, President and Chairman of the Board, effective August 31, 2011. As a result, the Board has appointed John Varian, a current Board member, as interim Chief Executive Officer and W. Denman Van Ness, XOMA's Lead Independent Director, as Chairman of the Board. The Board is initiating a search for a permanent Chief Executive Officer.

"During his four years at XOMA, Steve has led the team in the transformation of the Company into a more product-focused organization. His efforts resulted in the Servier collaboration for development and commercialization of XOMA 052 and enhancements to the research and biodefense programs, and he has built a strong management team aligned towards XOMA's long-term vision of becoming a commercial organization. On behalf of the Board, we wish to thank Steve for his dedicated service and are happy that he will remain available as a consultant in the coming months," commented Mr. Van Ness. "We also appreciate John stepping into the role of interim Chief Executive Officer as we seek a new CEO to lead XOMA going forward."

"It has been an honor to work with the many talented and dedicated people at XOMA. Together, we have made important progress in our goal to develop new drugs that have the potential to give patients better options to treat their diseases," said Mr. Engle. "I am looking forward to applying my expertise building life science companies in the future."

"Given our talented, capable management team, XOMA is well-positioned today to advance its product development programs led by XOMA 052, and we are prepared to maintain positive momentum in all of our core areas during this transition," Mr. Varian said. "Key pieces are in place that allow us to achieve our goal of discovering, developing and commercializing our own products in specialized U.S. markets, and we are presented with an opportunity to take a fresh look at our business, potentially finding additional ways to build value in the Company and for our shareholders. As we continue to execute on our programs, we will seek a permanent CEO who is ready to take XOMA to the next level."
