BioTime Plans Warrant Distribution to Shareholders

ALAMEDA, Calif.--(BUSINESS WIRE)--December 3, 2010--BioTime, Inc. (NYSE Amex: BTX) today announced that it plans to distribute new common share purchase warrants to the holders of BioTime common shares. Under the plan, shareholders will receive one warrant for every eight shares held. Each warrant will entitle the holder to purchase one common share for $12.00 per share. The warrants will expire four years after the date of issue. BioTime’s Board of Directors has not yet set a record date for determining shareholders entitled to receive the warrants. The warrants will be freely tradable, and BioTime plans to apply to list the warrants on the NYSE Amex.

BioTime expects the pharmaceutical industry and medical profession to increase their focus on regenerative medicine for a source of new therapies to treat degenerative diseases. The potential $72 million of proceeds from the exercise of the warrants may be used by BioTime and its subsidiaries to finance the growth and expansion of their current research and development programs and in any new programs that may be instituted in the future.

The distribution of the warrants will not occur until a registration statement for the warrants and underlying common shares is filed with the Securities and Exchange Commission and becomes effective under the Securities Act of 1933, as amended. This communication shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any State in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such State. BioTime reserves the right to cancel its plan to distribute the warrants or to change the terms and conditions of the warrants prior to the distribution of the warrants to its shareholders.
