BioTime Announces Non-Binding Letter of Intent with Geron Regarding Stem Cell Assets

BioTime, Inc. (NYSE MKT: BTX) and its recently formed subsidiary Biotime Acquisition Corporation (BAC) jointly announced today that they have entered into a non-binding letter of intent (LOI) with Geron Corporation. The LOI contains broad terms of a potential transaction through which Geron would contribute to BAC its intellectual property and other assets related to Geron’s discontinued human embryonic stem cell programs. BioTime would contribute to BAC $5 million in cash, $30 million of BioTime common shares, warrants to purchase eight (8) million common shares of BioTime at a pre-specified price, rights to use certain human embryonic stem cell lines, and minority stakes in two of BioTime’s subsidiaries. In addition, a private investor would invest $5 million in cash in BAC.

Following consummation of the potential transaction, Geron stockholders would receive shares representing 21.4% of the common stock of BAC as well as warrants to purchase 8 million shares of BioTime common stock at a pre-specified price. BioTime would own approximately 71.6%, and a private investor would own approximately 7.0% of the outstanding BAC common stock for their $5 million investment. BioTime would also receive warrants that would enable it to increase its ownership in BAC by approximately 2%, which would reduce the Geron stockholders’ ownership in BAC to 19.2%. BAC would also be committed to pay to Geron royalties on the sale of products that are commercialized in reliance upon Geron patents acquired by BAC.

The LOI is not a binding agreement to complete the transaction. Consummation of the transaction is necessarily subject to entering into a definitive agreement between the parties containing terms and conditions yet to be negotiated.

Kaye Scholer LLP and Thompson, Welch, Soroko & Gilbert LLP are acting as legal counsel to BioTime in connection with the acquisition of Geron’s stem cell assets.
