News Release

ALAMEDA, Calif.--(BUSINESS WIRE)--May. 21, 2012-- BioTime, Inc. (NYSE MKT: BTX) and its subsidiary LifeMap Sciences, Inc. today announced that they have completed the acquisition of XenneX, Inc. through a merger of XenneX into LifeMap Sciences. The definitive merger agreement was previously announced on April 20, 2012.

LifeMap Sciences now holds the exclusive, worldwide licenses to market GeneCards^® and PanDaTox from Yeda Research and Development Company Ltd, the technology transfer arm of the Weizmann Institute of Science in Israel. Developed by a leading bioinformatics team at the Weizmann Institute of Science, GeneCards^® is an online database that provides concise genomic, transcriptomic, genetic, proteomic, functional and disease-related information on all known and predicted human genes. With over 12 million page visits per year from hundreds of thousands of unique users worldwide, GeneCards^® is used by academia, research hospitals, patent offices, and leading biotech and pharma companies. PanDaTox is a recently developed, searchable database that can aid in the discovery of new antibiotics and biotechnologically beneficial products.

LifeMap Sciences’ goal is to be the leading resource for the emerging field of regenerative medicine, by providing access to GeneCards^®, and its LifeMap™ database of embryonic development and stem cells, and by also marketing research products manufactured by BioTime, including ACTCellerate^TM cell lines, HyStem^® hydrogels, and cell culture media.

LifeMap scientists will also utilize its databases to aid in the development of BioTime’s proprietary ACTCellerate™ human progenitor cell lines into products for the treatment of human diseases, especially degenerative diseases that might be treatable by cell replacement therapies.

Since 2003, XenneX has been commercializing GeneCards^® worldwide. Its customers include biotechnology, pharmaceutical and other life sciences companies, as well as organizations dealing with biotechnology intellectual property.

Through the merger, XenneX stockholders received 1,362,589 shares of LifeMap Sciences common stock, which represents approximately 13% of the LifeMap Sciences common stock now outstanding. XenneX shareholders also received 448,431 BioTime common shares as part of the transaction.

“The need for the LifeMap database is a reflection of the growth of the field of regenerative medicine,” said Michael D. West, Ph.D., BioTime’s Chief Executive Officer. “And the pace of this research is currently exponential, not linear. As a result, the scientific community today is very dependent on such relational databases. The LifeMap team is dedicated to building a quality resource in order to speed stem cell-based therapies to the clinic.”

David Warshawsky, Ph.D., LifeMap Sciences Chief Executive Officer, who also founded XenneX, Inc. in 2003, stated “By marketing GeneCards^® and PanDaTox, and the newly licensed MalaCards human disease database, alongside its LifeMap™ stem cell database and discovery platform, LifeMap Sciences will be the leading source of online database research tools for genetic, biological, and stem cell research and development. We are confident that our products will enhance research and provide life-saving cures in the future.”

About LifeMap Sciences, Inc.

LifeMap Sciences’ (www.lifemapsc.com) core technology and business is based on its integrated database suite, The go-to discovery and marketing platform for biomedical and stem-cell research. This platform will include GeneCards^®: the leading human gene database; the LifeMap™ database of embryonic development, stem cell research and regenerative medicine; and MalaCards, the human disease database. LifeMap Sciences also markets PanDaTox, a recently developed, searchable database that can aid in the discovery of new antibiotics and biotechnologically beneficial products.

In addition to database offerings, BioTime plans to make LifeMap Sciences BioTime’s principal marketing subsidiary for research products, including ACTCellerate™ human progenitor cell lines, GMP human embryonic stem (hES) cell lines, hES cell lines carrying inherited genetic diseases, and ESpan™ growth media for progenitor cell lines for non-therapeutic uses. LifeMap Sciences will utilize its databases as part of its online marketing strategy to reach life sciences researchers at biotech and pharmaceutical companies and at academic institutions and research hospitals worldwide.

In a therapeutic discovery collaboration with BioTime, LifeMap’s scientists will utilize LifeMap’s proprietary discovery platform and stem cell database along with the GeneCards^® and MalaCards integrated database suite, to aid in the development of BioTime’s proprietary ACTCellerate™ human progenitor cell lines into products for the treatment of human diseases, especially degenerative diseases that might be treatable with cell replacement therapies. The LifeMap™ discovery platform will be used to select the progenitor cell lines that are most likely to be useful in developing cell-based regenerative medicine therapies for a wide range of diseases.
