ALAMEDA, Calif. -- March 7, 2013

BioTime, Inc. (NYSE MKT: BTX) today announced it has amended its $5 million
Stock and Warrant Purchase Agreement with Romulus Films, Ltd., originally
signed on January 4, 2013. Through the amendment, BioTime and Romulus have
agreed to accelerate the closing date for the $3 million second tranche of the
$5 million financing. The first $2 million tranche under the agreement was
funded in January 2013. The second tranche was originally intended to close
later this year concurrent with the closing of the acquisition of certain stem
cell assets by BioTime’s subsidiary BioTime Acquisition Corporation (BAC)
pursuant to an Asset Contribution Agreement among BioTime, BAC, and Geron
Corporation. Under the amendment, the remaining $3 million investment in
BioTime will be funded on April 10, 2013. Romulus has also committed to invest
$5 million in BAC in conjunction with the consummation of the stem cell asset
acquisition, which is expected to occur later this year.

BioTime plans to use the proceeds from this financing to fund its planned $5
million cash investment in BAC. BioTime will advance funds to BAC to finance
BAC’s continued progress in preparation for the completion of the stem cell
asset acquisition transaction. Since Romulus and BioTime signed their
agreement in January, a 24,000 sq. ft. research facility has been leased for
use by BAC, and BAC has acquired equipment for its research facility,
recruited experienced senior research and product development management
personnel, and worked to establish relationships with academic institutions
and potential commercial development partners.

BioTime has raised gross proceeds of approximately $14.6 million since October
2012, including the $2 million first tranche of the equity financing from
Romulus, and approximately $12.6 million from the sale of approximately 2.9
million common shares at a weighted average price of $4.34 per share in the
open market. The 2.9 million shares were sold through BioTime’s $25 million
Controlled Equity Offering facility with Cantor Fitzgerald & Co., as sales
agent, and through the sale of BioTime shares held by its majority owned
subsidiaries, LifeMap Sciences, Inc. and Cell Cure Neurosciences Ltd.

“These funds, plus the commitment from Romulus Films to invest $5 million in
BAC upon closing the stem cell asset acquisition transaction, will
significantly strengthen our balance sheet and our ability to execute on our
operating plan over the coming year, including financing the initiation of
planned clinical trials of Renevia™ and PanC-Dx™,” said Peter Garcia,
BioTime’s Chief Financial Officer.

Jonathan Woolf, Director of Romulus Films, a United Kingdom based investment
company, said, “As a significant and long-term investor in Geron Corporation,
we are very pleased to be supporting BioTime and BAC in the acquisition of
Geron’s embryonic stem cell assets. We believe these assets,which had shown
early success and were considered to be world-leading prior to discontinuation
by Geron in late 2011, may have the potential to revolutionize medicine and
provide untold benefits to patients in the future in many significant and
unmet areas of disease prevention and cure. We are pleased with BAC’s progress
announced today, as well as the progress that BioTime and its subsidiaries
have announced in recent months with their product development programs.To
support these developments, we have agreed to accelerate part of our
investment in BioTime. We believe that after the stem cell asset acquisition
transaction is completed, BAC and the BioTime family of companies will hold
the largest concentration of stem cell and regenerative medicine assets and
experience in the world.”
