BIOTIME INC. ANNOUNCES FIRST QUARTER 2008 FINANCIAL RESULTS

-- Reports Growth in First Quarter Royalty Revenue --

-- Expects Continued Growth in Royalty Revenue for Second Quarter --

ALAMEDA, CA, May 19, 2008 – On May 15, 2008 BioTime, Inc. (OTCBB: BTIM) reported financial results for the first quarter ended March 31, 2008.

For the three months ended March 31, 2008, BioTime's total quarterly revenue, including both royalty income and revenue recognition of deferred license fees, increased 55% to $381,018 versus $245,698 for the same period last year.

BioTime reported a net loss of $476,048, or $0.02 per basic and diluted share, for the three months ended March 31, 2008, compared to a net loss of $553,862, or $0.02 per basic and diluted share, for the three months ended March 31, 2007.

BioTime recognized $308,900 in royalty revenue versus $199,264 during the three months ended March 31, 2007, an increase of 55%. The growth in royalties is attributable to the increase in sales of Hextend to both hospitals and the United States Armed Forces.  Hextend is an artificial colloidal solution classified as a plasma volume expander for supporting oncotic pressure as well as providing electrolytes to patients suffering from blood loss in surgery or from trauma. BioTime recognizes royalty revenues in the quarter in which sales reports are received versus the quarter in which the sales take place.  Therefore, royalty revenue for the three months ended March 31, 2008 includes royalties on sales of Hextend during the three months ended December 31, 2007.

Additionally, in April 2008, BioTime received royalties in the amount of $341,153 from Hospira, Inc., an increase of 108% from the same period one year ago. This amount is based on the sales of Hextend made by Hospira, Inc. during the first quarter of 2008, and will be reflected in BioTime’s consolidated financial statements for the second quarter of 2008.  The growth is also attributable to increased sales both to hospitals and the United States Armed Forces.  Hospira is the exclusive distributor of Hextend in the United States. CJ CheilJedang Corp. is the exclusive distributor of Hextend in South Korea.

Michael D. West, Ph.D, BioTime’s Chief Executive Officer, noted, “Our primary pharmaceutical product, Hextend®, continues to gain traction among hospitals in the United States and abroad. Further, knowing that Hextend is assisting medical efforts to save lives, including the lives of the members of our Armed Forces, is a great source of pride for our company.” Dr. West continued, “BioTime has recently entered the field of regenerative medicine through our wholly owned subsidiary Embryome Sciences, Inc., which plans to develop new medical research products using embryonic stem cell technology.  We believe that stem cell technology will have broad application in medicine and will likely be one of the leading technology platforms of the coming decades.”

License revenue increased 42.5% to $66,183 during the first quarter of 2008 versus $46,434 in the same period last year. Most of this increase consists of license fees received during prior accounting periods from CJ CheilJedang Corp. and Summit Pharmaceuticals International Corporation, and are reflected as deferred revenue on BioTime’s balance sheet.  BioTime amortizes those license fees and recognizes them as current revenues over the expected life of the patents related to the applicable licenses.

Cash and cash equivalents totaled $307,471 as of March 31, 2008, compared with $277,280 as of March 31, 2007.  Total shareholder deficit was $3,349,599 as of March 31, 2008, compared with total shareholders' deficit of $2,372,548 at March 31, 2007, a 41% increase.  As of March 31, 2008, the Company had lines of credit for $2,578,600, from which $1,265,519 had been drawn at that date. The Company drew an additional $575,000 on one of our lines of credit during April 2008.

It is BioTime’s intention to raise the additional capital needed to finance the further development of its products because its current lines of credit and royalty revenues are not sufficient to fund anticipated operating expenses beyond November 15, 2008.
