Press Release

BioTime, Inc. (NYSE Amex:BTX), a biotechnology company that develops and markets products in the field of regenerative medicine, today reported financial results for the third quarter and nine months ended September 30, 2011 and highlighted recent corporate accomplishments.

"The key to building the leading company in the emerging field of regenerative medicine is the identification of a strategy for the rapid development and commercialization of significant therapeutic products. Our strategy is the development of near-term acellular therapeutic products that segue into the subsequent deep product pipeline enabled by the new pluripotent stem cell technologies," said Michael D. West, Ph.D., BioTime's President and CEO. "We are on track for human clinical trials in 2012 for HyStem^®-Rx as a medical device for the delivery of adipose stem cells for reconstructive surgery and transplantation. This development of HyStem^®-Rx is intended to lead to the development of a wide array of related cell delivery and tissue matrix products, including combination products of HyStem^®-Rx with BioTime's ACTCellerate^TMcells. There is growing interest in both industry and academia in our research-grade products currently on the market. The sale of these products is part of our strategy to simultaneously keep our burn rate relatively low, while leveraging the research being performed in numerous academic laboratories around the world. This phased product flow, combined with the value that has been created in our disease-focused subsidiaries, is a reflection of our global plan to lead in the commercial development of regenerative medicine and maximize value creation for our shareholders."

Financial Results

Revenue (including royalties from product sales and other revenue, revenue recognition of deferred license fees and grant income) for the quarter ended September 30, 2011 was $1.1 million, up 40% from $815 thousand for the same period one year ago. For the nine months ended September 30, 2011, revenue increased 20% to $2.7 million, compared to $2.3 million in the same period of 2010. The increase in revenue year-over-year is primarily attributable to a significant increase in grant income and research product sales. The increase in revenue was slightly offset by a decrease in royalties from the sale of Hextend^®, BioTime's blood plasma expander product, and license fees related to Hextend^®.

Total expense for the three months ended September 30, 2011 was $5.4 million, compared to a total expense of $3.3 million for the same period in the prior year. Total expense for the nine months ended September 30, 2011 was $15.9 million, compared to $8.4 million for the same period of 2010. Both research and development and general and administrative expenses increased year-over-year primarily due to the acquisition of ES Cell International Pte. Ltd., Cell Targeting, Inc., Glycosan BioSystems, Inc., and a majority interest in Cell Cure Neurosciences Ltd. and due to increased research and development programs in other BioTime subsidiaries. Expenses from BioTime subsidiaries have been funded in part by equity investments from the minority shareholders of those subsidiaries.

Net loss attributable to BioTime, Inc. for the three months ended September 30, 2011 was $3.7 million or $0.08 per share, compared to a net loss of $4.7 million or $0.11 per share for the same period one year ago. For the nine months ended September 30, 2011, net loss was approximately $11.2 million or $0.23 per share, compared to net loss of $8.2 million or $0.22 per share for the same period of 2010.

Net cash used in operating activities was $3.6 million for the three months ended September 30, 2011 compared to $2.0 million for the three months ended September 30, 2010, again reflecting the expansion of operations and the increased cost of research and development programs in BioTime subsidiaries. On a year to date basis, for the nine months ended September 30, 2011, net cash used in operating activities was $10.0 million, compared to $5.0 million for the same period in 2010.

Cash and cash equivalents totaled $26.2 million as of September 30, 2011, compared with $33.3 million as of December 31, 2010. On August 23, 2011, BioTime subsidiary, Oncocyte Corporation, received a $10 million equity investment. This investment included a $3 million cash investment from an outside investor for the issuance of shares of common stock and a $7 million investment from BioTime, which included $1 million in cash and 1,286,174 in BioTime common shares (with $6 million in market value). The issuance of the common shares from BioTime to Oncocyte is accounted for as Treasury Stock on a consolidated basis.

Third Quarter and Recent Corporate Accomplishments

• Issued the second of two U.S. patents covering the composition of Glycosan hydrogels manufactured by BioTime's subsidiary, OrthoCyte Corporation (US Patent Number 7,981,871). Glycosan hydrogels include products developed for use in stem cell research and HyStem^®-Rx, a product slated for near-term development as a medical device for the delivery of adipose tissue or other adult stem cells or therapeutic cells derived from embryonic stem cells in reconstructive surgery and other surgical procedures.
• Awarded a Small Business Innovation Research grant from the National Institutes of Health for $335,900, to develop HyStem^® microcarriers for the propagation of human stem cells and as a means of cell delivery for human clinical applications.
• Announced the approval of an additional four ESI human embryonic stem cell lines, ESI-035. ESI-049, ESI-051 and ESI-053, for inclusion in the National Institutes of Health Human Embryonic Stem Cell Registry, allowing use of these lines in federally funded research.
• Completed a $10 million equity financing by BioTime's subsidiary, Oncocyte Corporation, to expand its development of diagnostics and therapeutics for cancer in humans. The financing included $4 million in cash ($3 million from an outside investor and $1 million from BioTime) combined with $6 million of BioTime common shares.
• Entered into a worldwide license agreement with Cornell University for the worldwide development and commercialization of technology developed at Weill Cornell Medical College for the differentiation of human embryonic stem cells into vascular endothelial cells. The technology may provide an improved means of generating vascular endothelial cells on an industrial scale, and will be utilized by us in diverse products, including those under development at our subsidiary ReCyte Therapeutics, Inc. to treat age-related vascular disease, and products being developed at our subsidiary OncoCyte Corporation targeting the delivery of toxic payloads to the developing blood vessels of cancerous tumors.
• Entered into a Sponsored Research Agreement under which scientists at Weill Cornell Medical College will engage in research with the goals of: verifying the ability of progenitor cells, derived by our subsidiary ReCyte Therapeutics, Inc. using our ACTCellerate technology, to generate stable populations of vascular endothelial cells; testing the functionality and transplantability of the vascular endothelial cells in animal models to see if the transplanted cells generate new vascular tissue; and using Glycosan hydrogels, produced by our subsidiary OrthoCyte Corporation, as "scaffolds" for the three-dimensional propagation of vascular endothelial cells into vascular tissues suitable for transplantation.
• Presented favorable toxicology results in pre-clinical studies of Hystem^®-Rx in the brains of laboratory mice. Hystem^®-Rx is being developed as an implantable cell delivery device that may have use in a variety of cell and tissue transplant therapies being developed to treat osteoarthritis, brain tumors, and wound healing.
• Appointed Peter S. Garcia as BioTime's Chief Financial Officer. Mr. Garcia served as Chief Financial Officer of six biotech and high-tech companies over the past 15 years, and was instrumental in raising over $500 million and leading multiple merger and acquisition transactions for those companies.
• Published in the peer-reviewed journal, Stem Cell Research, the complete genome sequence analysis of five clinical-grade human embryonic stem cell lines. "Evaluating the Genomic and Sequence Integrity of Human ES Cell Lines: Comparison to Normal Genomes" is the first such analysis of the entire genome of human embryonic stem cell lines and further establishes BioTime's lead in developing fully characterized cell lines intended for use in the manufacture of therapeutics.
• Presented at the following scientific and investor meetings: Stem Cells USA & Regenerative Medicine Congress 2011; Rodman & Renshaw 13^th Annual Healthcare Conference; GTC 2011 5th Advances in Stem Cell Discovery & Development Conference; and Translational Strategies for Tissue Engineering Conference.
