BioTime Subsidiary OncoCyte Corporation Receives

Second $2,000,000 Equity Tranche;

BioTime Plans Additional $2,250,000 Investment

ALAMEDA, CA, January 7, 2010 – BioTime, Inc. (NYSE Amex: BTIM) announced that its subsidiary OncoCyte Corporation has completed the funding of the second tranche of a private equity offering through the sale of 3,000,000 shares of OncoCyte common stock for $2,000,000 to a private investor.  BioTime plans to invest an additional $2,250,000 of its own cash in OncoCyte during the first quarter of 2010.  OncoCyte plans to use these funds to accelerate its research efforts and to further develop its management team, staff, and business.

OncoCyte’s therapeutic strategy and goal is to utilize human embryonic stem cell technology to create genetically modified stem cells capable of homing to specific malignant tumors while carrying genes that can cause the destruction of the cancer cells.  This therapeutic use of human embryonic stem cells differs from most proposed industrial uses of stem cell technology in that OncoCyte’s goal is not the stable engraftment of the cells to regenerate tissue function, but rather a use of the unique properties of stem cells as a tool to eliminate malignant cells.  OncoCyte believes that its unique therapeutic strategy may be well-suited to the treatment of certain cancers for which no current therapies are effective, therefore fulfilling a current high unmet medical need.

OncoCyte is also organizing a Scientific Advisory Board of accomplished cancer physicians and researchers to provide advice and support for OncoCyte's scientific research and product development activities.  The initial members of the Scientific Advisory Board are Daopei Lu, M.D., Frank McCormick, Ph.D., W. Michael Korn, M.D., and Evan Y. Snyder, M.D., Ph.D.

In order to fund its planned additional investment of $2,250,000 in OncoCyte, and to fund other new opportunities, BioTime also announced today that it plans to offer holders of its common share purchase warrants listed on the NYSE Amex the opportunity, for a limited period of time, to exercise up to 3,000,000 warrants at a price of $1.70 per share, which represents a discount of $0.30 from the regular warrant exercise price of $2.00 per share.  After the expiration of the discount offer, the exercise price of the warrants will revert to $2.00 per share.  The commencement and expiration dates of the warrant discount offer have not yet been determined.  A post-effective amendment to a registration statement relating to the warrants and the discount offer has been filed with the Securities and Exchange Commission but has not yet become effective.  The warrant discount offer will not commence until the post-effective amendment to the registration statement becomes effective.
