                   BioTime Announces Third Quarter Results

     *  Total Revenues Increase by 55% During the Third Quarter

     *  52% Increase in Royalty Revenue Recorded on Hextend Sales for the
        Third Quarter

     *  Company Continues to Make Progress in Efforts for International
        Expansion of Hextend

    BERKELEY, Calif., Nov. 16 /PRNewswire-FirstCall/ -- BioTime, Inc.
(Amex: BTX) today announced financial results for the third quarter ended
September 30, 2004.
    Royalty revenues from Hextend(R) product sales by Hospira, Inc. increased
52% to $145,208 for the third quarter of 2004, from $95,807 during the same
period last year.  BioTime's total quarterly revenue increased by 55% to
$170,381 for the third quarter of 2004, from $109,870 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 September 30, 2004 included
royalties on sales made by Hospira during the three months ended June 30,
2004.
    In November 2004, BioTime received $147,148 in royalties from Hospira
based on Hextend sales during the three months ended September 30, 2004.  This
revenue will be reflected in the Company's financial statements for the fourth
quarter ending December 31, 2004.  Royalties increased 48% from the $99,674
received during the same period last year.  Hospira sales of Hextend to
hospitals continued to improve during the three months ended September 30,
2004 and we achieved the highest quarterly total in the history of our
Company.  This was offset by fewer sales to the U.S. Armed Forces, resulting
in modest third quarter sequential growth.  Although Hextend is the preferred
resuscitation fluid of the U.S. Special Operations Command, the military's
purchase of Hextend in intermittent, large volume orders, makes sales to them
difficult to predict in subsequent quarters.  During the same period last
year, BioTime received $238,571 in total revenues from Abbott Laboratories,
Hospira's former parent, which included $138,897 due at that time to preserve
certain rights under their license, and $99,674 in royalties described above.
    Research and development expenses for the third quarter of 2004 totaled
$305,626, compared to $239,760 for the third quarter of 2003.  The increase
was primarily attributable to an increase in fees paid to scientific
consultants and an increase in salaries allocated to research and development.
General and administrative expenses for the third quarter of 2004 totaled
$280,712, compared to $227,432 for the same period last year.  The increase in
general and administrative expenses is chiefly attributable to an increase in
legal fees, general and administrative salaries, and investor relations
expenses.
    For the three months ended September 30, 2004, BioTime generated a total
of $13,415 of net interest and other income with no offsetting interest
expense, compared to net interest and other income of $1,007,945 during the
same period last year, then offset by an interest expense of $288,603.  The
difference is due to the fact that the Company has paid off its debenture debt
and is no longer incurring the associated interest expense.  Also, $1,000,000
of the interest and other income generated in 2003 was attributable to
proceeds from a key man life insurance policy collected after the death of
former Chairman and CEO, Paul Segall.
    BioTime reported a net loss of $(452,060), or $(0.03) per basic and
diluted share, for the three months ended September 30, 2004, compared to net
income of $362,020, or $0.03 per basic and diluted share, for the three months
ended September 30, 2003.  The 2003 results reflected the collection of the
life insurance payment included in interest and other income.
    Cash and cash equivalents totaled $1,568,845 at September 30, 2004,
compared with $717,184 at December 31, 2003.  Total shareholders' equity was
$880,129 at September 30, 2004, compared with total shareholders' deficit of
$(2,430,551) at December 31, 2003.  As of September 30, 2004, the Company had
no long-term debt.
    "The third quarter's results once again confirm the strong operating
momentum BioTime is generating -- especially with respect to sales of
Hextend," said Judith Segall, BioTime Vice President of Operations, Office of
the President.  "Another promising development for BioTime is the excellent
progress we're making in the global expansion of Hextend.  As we announced
last quarter, our South Korean partner, CJ Corp., is expected to be the first
to distribute Hextend beyond North America with an anticipated market launch
early next year."
