           BioTime Announces Strong Royalty Revenue Increase for First
                                  Quarter 2004


    BERKELEY, Calif.--(BUSINESS WIRE)--May 13, 2004--BioTime, Inc.
(AMEX:BTX):

    --  20% Increase in Royalty Revenue Recognized on Hextend(R) Sales
        for First Quarter

    --  35% Increase in Total Revenue for First Quarter

    --  118% Increase in Hextend Royalties on Hextend Sales during
        First Quarter

    --  Abbott Laboratories Assigns Hextend License to Hospital
        Products Spin-off Hospira, Inc.

    --  Successful Rights Offering Completed; Long-Term Debt
        Eliminated

    BioTime, Inc. (AMEX:BTX) today announced financial results for the first
quarter ended March 31, 2004.
    Royalty revenues from Hextend(R) product sales by Abbott Laboratories
increased 20% to $115,887 for the first quarter of 2004, from $96,622 during the
same period last year. BioTime's total quarterly revenue increased 35% to
$130,700 for the first quarter of 2004, from $96,622 for the same period last
year. The Company recognizes royalty revenues in the quarter in which the sales
report is received, rather than the quarter in which the sales took place.
Therefore, revenues for the three months ended March 31, 2004 included royalties
on sales made by Abbott during the three months ended December 31, 2003.
    BioTime received $181,274 in royalties from Abbott Laboratories based on
Hextend sales during the three months ended March 31, 2004. This represents an
increase of 118% over royalties of $83,234 received during the same period last
year. This revenue will be recognized in the Company's financial statements for
the second quarter ending June 30, 2004.
    "Hextend sales to the U.S. Armed Forces during the first three months of
this year contributed to a significant portion of the increase in royalties we
received," said Judith Segall, BioTime Vice President of Operations, Office of
the President. "Hextend is the preferred resuscitation fluid of the U.S. Special
Operations Command. Because the military purchases Hextend in intermittent,
large volume orders, it is difficult to predict sales to them in subsequent
quarters."
    "Increased sales of Hextend to hospitals during the first quarter also
contributed to higher royalties received. The use of Hextend in leading U.S.
hospitals and teaching universities, hospital chains and HMOs offers a valuable
endorsement of its medical importance, and points to favorable long-term sales
growth potential as use of the product begins to proliferate within smaller
hospitals around the nation," Segall added.
    Effective May 3, 2004, Abbott Laboratories, BioTime's exclusive North
American licensing partner for Hextend, spun off most of its hospital products
division business into a new company called Hospira, Inc. (NYSE: HSP). Hospira
is among the largest hospital products manufacturers in the U.S., and Abbott's
license to manufacture and market Hextend has been assigned to the new company.
    Research and development expenses for the first quarter of 2004 totaled
$227,806, compared to $224,536 for the first quarter of 2003. The increase was
primarily attributable to an increase in outside research costs. General and
administrative expenses for the first quarter of 2004 totaled $408,392, compared
to $337,768. The increase in general and administrative expenses was primarily
due to increases in printing costs, general and administrative consulting fees,
and trademark expenses; partially offset by decreases in legal and accounting
fees.
    BioTime completed a subscription rights offer of common stock and warrants
during January 2004, raising $3,584,424 through the sale of 2,560,303 common
shares and 1,280,073 warrants. Following the completion of the rights offer,
BioTime raised an additional $600,000 by selling an additional 428,571 common
shares and 214,284 warrants under a Standby Purchase Agreement to certain
persons who acted as Guarantors of the rights offer. BioTime was able to
eliminate its $3,350,000 of debenture indebtedness during the first quarter of
2004 by using a portion of the proceeds of the rights offer to repay $1,850,000
of debentures in cash, and by issuing a total of 1,071,428 common shares and
535,712 common share purchase warrants in exchange for $1,500,000 of debentures.
    Net interest expense totaled $1,137,444 for the three months ended March 31,
2004, compared to net interest expense of $205,447 for the three months ended
March 31, 2003. The increase reflects interest expense of $1,106,392
attributable to the excess of the fair value of consideration given to the
debenture holders who exchanged their debentures for BioTime common shares and
warrants over the carrying amount of the debentures at the time of the exchange.
    BioTime reported a net loss of $(1,642,942), or $(0.10) per basic and
diluted share, for the three months ended March 31, 2004, compared to a net loss
of $(751,129), or $(0.06) per basic and diluted share, for the three months
ended March 31, 2003.
    Cash and cash equivalents totaled $2,119,803 at March 31, 2004, compared
with $717,184 at December 31, 2003. Total shareholders' equity was $1,702,400 at
March 31, 2004, compared with total shareholders' deficit of $(2,430,551) at
December 31, 2003. As of March 31, 2004, the Company had no long-term debt.
