BioTime, Inc. (NYSE Amex:BTIM) announced the completion of its warrant discount offer which closed at 5:00 p.m., New York time, on August 18, 2010. The deadline for submitting warrant certificates and exercise funds under notices for guaranteed delivery is August 23, 2010 at 5:00 p.m., New York time.

Based upon preliminary results, the warrant discount offer generated $9,195,422 of proceeds to BioTime from the exercise of warrants to purchase 5,057,988 BioTime common shares at the discounted price of $1.818 per share. As a result of the completion of the discount offer, BioTime will have approximately $25 million of cash and cash equivalents on hand, with essentially no debt other than regular trade payables.

Approximately 2.3 million of BioTime’s publicly traded warrants were not exercised in the discount offer and remain outstanding. Those warrants will continue to trade on NYSE Amex under the symbol BTIM.WS and may be exercised at the original exercise price of $2.00 per share until 5:00 p.m., New York time, on October 31, 2010, at which time the warrants will expire and will no longer be exercisable. If the remaining 2.3 million warrants are exercised in full, BioTime will realize additional proceeds of approximately $4.6 million.

BioTime intends to use the capital raised through the warrant exercises in the discount offer to strengthen its working capital reserves and for the expansion of its stem cell product development, including product development being undertaken at its subsidiaries Embryome Sciences, Inc., OncoCyte Corporation, OrthoCyte Corporation, BioTime Asia, Limited, and ES Cell International Pte Ltd, and at Cell Cure Neurosciences Ltd. BioTime may also use a portion of the proceeds to begin human clinical trials for new indications of its lead product Hextend ®, including the treatment of severe childhood malaria by reducing the acidosis and hypovolemia that accompany this disease and often result in fatalities.
