ALAMEDA, Calif. & TEL AVIV, Israel–(BUSINESS WIRE)–BioTime, Inc. (NYSE MKT: BTX), a biotechnology company focused on the
development and commercialization of cell-based therapies, announced
today that the Tel Aviv Stock Exchange (TASE) has approved the new
listing of BioTime’s common shares beginning on Tuesday, September 8,

capitalization, BioTime’s shares are anticipated to be included in five
TASE equity indexes: TASE’s TA-75, TA-100, TA-BlueTech, TA-Tech-Elite
and TA-Biomed.

“We believe that the dual listing on the TASE will help us to open a new
access point for our shares in the Israeli market that is becoming a
center for biomed and emerging technology companies,” said Michael D.
West, Ph.D., CEO of BioTime. “The new listing also offers an opportunity
to expand and diversify our shareholder base by increasing our exposure
and improving our accessibility to Israeli investors.”

TASE CEO, Yossi Beinart said, “We welcome BioTime to the Tel Aviv Stock
Exchange Dual Listing, and believe that this is a recognition of the
Biomed sector’s special position at the Tel Aviv Stock Exchange. BioTime
joins a group of 46 cross-listed companies entitling them to significant
benefits including, added exposure among Israeli investors, extension of
the trading day, investment by Exchange Traded Product vendors, and easy
access to institutional and retail investors as well as to global growth
companies.”

BioTime considers this listing a natural extension of its long-standing
relationship with the Israeli biotechnology industry, including its two
Israeli subsidiaries Cell Cure Neurosciences Ltd. (“Cell Cure”) of
Jerusalem and LifeMap Sciences Ltd. of Tel Aviv which has benefited from
a rewarding relationship with the Weizmann Institute of Science.

In conjunction with the Hadassah Human Embryonic Stem Cell Research
Center at Hadassah University Medical Center, BioTime’s Jerusalem-based
subsidiary Cell Cure is currently conducting a Phase I/IIa clinical
trial of its lead product OpRegen®, the first cell
therapy product derived from human embryonic stem cells (ESCs) ever to
undergo clinical testing in Israel. Utilizing retinal pigment epithelial
(RPE) cells derived from ESCs, the OpRegen® trial is
targeting the dry form of age-related macular degeneration (AMD). AMD is
the number one cause of blindness in the elderly in the developed world.
The clinical trial is being funded in part by a grant from the Office of
the Chief Scientist (OCS).
