PURCHASE AGREEMENT

This Agreement is entered into by Romulus Films Ltd. (“Purchaser”) and BioTime Acquisition Corporation, a Delaware corporation (the “Company).

Purchase and Sale of Shares and Warrants.

(a) Purchaser hereby irrevocably agrees to purchase, and the Company hereby irrevocably agrees to sell to Purchaser 2,136,000 shares of Series B Common Stock, par value $0.0001 per share (“Shares”), of the Company and warrants to purchase 350,000 shares of Series B Common Stock of the Company (“Warrants”). The Warrants will entitle the holder to purchase, on the terms and conditions set forth in the Warrant Agreement governing the Warrant, shares of Series B Common Stock, par value $0.0001 of the Company (“Warrant Shares”) for $5.00 per Warrant Share (the “Warrant Price”), subject to adjustment as provided in the Warrant Agreement a copy of which is attached as Exhibit A (the “Warrant Agreement”).

2. Closing. The consummation of the sale of the Shares and Warrants (“Closing”) will take place concurrently with the closing of the “Stem Cell Transaction.” The Stem Cell Transaction means a transaction among the Company, BioTime, Inc. (“BioTime”), and Geron Corp. (“Geron”) pursuant to which Geron and BioTime will contribute certain assets to the Company in exchange for shares of Company common stock, and in the case of the BioTime, warrants of the same tenor as the Warrants being purchased by Purchaser under this Agreement, as set forth in an Asset Contribution Agreement among the Company, BioTime and Geron.

(a) The Company shall give Purchaser not less than five (5) business days prior notice of the date on which the Closing will take place (“Closing Date”). On the Closing Date, Purchaser shall purchase all 2,136,000 Shares and 350,000 Warrants and shall pay to the Company, by wire transfer to an account designated by the Company, the full purchase price of such Shares and Warrants. On the Closing Date, the Company will issue to the Purchaser the Shares and Warrants purchased.

(b) The issue of the Shares purchased may be, at the election of the Company, by book entry of such Shares purchased, in the name of the Purchaser, on the records of the transfer agent of the Shares or by a stock certificate in the name of the Purchaser for the number of Shares purchased. Warrants purchased shall be delivered to the Purchaser upon the Closing Date, along with a copy of the Warrant Agreement governing the Warrants executed by the Company.

(i) The representations and warranties of the Company contained in this Agreement shall be true and correct in all material respects on the date of the Closing, and the Company shall have complied in all material respects with its covenants required to have been performed as of the date of Closing;

(ii) No event shall have occurred that has had, or is reasonably expected to have, a Material Adverse Effect;

(iii) No litigation or other proceeding of any kind to enjoin, delay, prohibit or restrict the consummation of the sale of the Shares and Warrants under this Agreement, or the Stem Cell Transaction shall be pending, and there shall be no judgment, order or writ of any court or government authority in effect prohibiting or restricting the consummation of the of the sale of the Shares and Warrants under this Agreement, or consummation of the Stem Cell Transaction by any party;

(iv) The Asset Contribution Agreement shall not have been amended in any material respect from the date of its execution by the parties thereto, and neither BAC nor BioTime shall have waived any material condition to their respective obligations to consummate the Stem Cell Transaction under the Asset Contribution Agreement, except for such amendments or waivers as Purchaser shall have approved in writing; provided, that such approval by Purchaser shall not to be unreasonably withheld or delayed; and

(v) The Stem Cell Transaction shall have closed or shall close concurrently with the Closing.

(d) As used in this Agreement, “Material Adverse Effect” shall mean any change that does, or would be reasonably expected to, have a material adverse effect on the business, operations, financial condition, or assets of the Company on a consolidated basis, provided, however, that none of the following shall be deemed either alone or in combination to constitute, and none of the following shall be taken into account in determining whether there has been or would be, a Material Adverse Effect: (a) any adverse effect resulting from or arising out of the announcement, pendency, or consummation of the transactions contemplated by this Agreement or the Stem Cell Transaction; (b) any adverse effect resulting from or arising out of general economic conditions; (c) any adverse effect resulting from or arising out of general conditions in the industries in which the Company or Geron operates; (d) any adverse effect resulting from or arising out of any natural disaster or any acts of terrorism, sabotage, military action or war or any escalation or worsening thereof; and (e) any adverse effect resulting from or arising out of any changes in any law, statute, rule or regulation, or the judicial or administrative interpretation thereof, or any change in generally accepted accounting principles.

3. Registration Rights. Concurrently with the execution and delivery of this Agreement, Purchaser and the Company shall enter into a Registration Rights Agreement in the form of Exhibit B, pursuant to which the Company is agreeing to register the Shares, the Warrants and the Warrant Shares under the Securities Act of 1933, as amended (the “Act”).

5. Investment Representations. Purchaser represents and warrants to the Company that:

(a) Authority; Enforceability. The Purchaser has the corporate power and authority to execute and deliver, and to perform all of its obligations under, this Agreement and the Registration Rights Agreement. The execution and delivery of this Agreement and the Registration Rights Agreement, and the performance by the Purchaser of its obligations under this Agreement and the Registration Rights Agreement, have been duly authorized by all necessary action on the part of the Board of Directors or similar governing body of the Purchaser. This Agreement and the Registration Rights Agreement are the valid and binding agreements of the Purchaser, enforceable in accordance with their respective terms, except to the extent limited by any bankruptcy, insolvency, or similar law affecting the rights of creditors generally.

(b) No Conflict. The execution and delivery of this Agreement and the Registration Rights Agreement, and consummation of the transactions contemplated under this Agreement and under the Registration Rights Agreement, including the purchase of the Shares and Warrants, by the Purchaser do not and will not violate any provisions of (i) any rule, regulation, statute, or law applicable to the Purchaser or (ii) the terms of any order, writ, or decree of any court or judicial or regulatory authority or body by which the Purchaser is bound, or (iii) the articles of incorporation, bylaws, or similar charter or governing documents of the Purchaser.

(c) Due Diligence. Purchaser has made such investigation of the Company as Purchaser deemed appropriate for determining to acquire (and thereby make an investment in) the Shares and Warrants. In making such investigation, Purchaser has had access to such financial and other information concerning the Company as Purchaser requested. Purchaser has received and read copies of the form of Warrant Agreement, including the form of the Warrant, the form of Registration Rights Agreement, the draft documents listed on Schedule I related to the Stem Cell Transaction, the Certificate of Incorporation of the Company and an Amended and Restated Certificate of Incorporation of the Company that will become effective in connection with the Stem Cell Transaction, and the Bylaws of the Company, which together with this Agreement constitute the “Disclosure Documents.” Purchaser is relying on the information provided in the Disclosure Documents or otherwise communicated to Purchaser in writing by the Company. Purchaser has not relied on any statement or representations inconsistent with those contained in the Disclosure Documents or otherwise communicated to Purchaser in writing by the Company. Purchaser has had a reasonable opportunity to ask questions of and receive answers from the executive officers of the Company concerning the Company, and to obtain additional information (including all exhibits listed in the Disclosure Documents), to the extent possessed or obtainable by the Company without unreasonable effort or expense, necessary to verify the information in the Disclosure Documents. All such questions have been answered to Purchaser’s satisfaction.

(d) Unregistered Offer and Sale. Purchaser understands that the Shares and Warrants are being offered and sold without registration under the Act, or qualification under the California Corporate Securities Law of 1968, or under the laws of any other states of the United States, or the laws of England or the United Kingdom, or any other country, in reliance upon the exemptions from such registration and qualification requirements. Purchaser acknowledges and understands that the availability of the aforesaid exemptions depends in part upon the accuracy of certain of the representations, declarations and warranties made by Purchaser, and the information provided by Purchaser, in this Agreement, Purchaser is making such representations, declarations and warranties, and is providing such information, with the intent that the same may be relied upon by the Company and its officers and directors in determining Purchaser’s suitability to acquire the Shares and Warrants. Purchaser understands and acknowledges that no English or United Kingdom or United States federal, state or other agency has reviewed or endorsed the offering of the Shares and Warrants or made any finding or determination as to the fairness of the offering or sale of the Shares and Warrants or the completeness of the information in the Disclosure Documents.

(e) Restrictions on Exercise and Transfer. Purchaser understands that the Shares and Warrants may not be offered, sold, or transferred in any manner, and the Warrants may not be exercised, unless subsequently registered under the Act, or unless there is an exemption from such registration available for such offer, sale or transfer.

(f) Knowledge and Experience. Purchaser (or if Purchaser is not a natural person, the officers and directors making the decision on behalf of Purchaser to purchase the Shares and Warrants) has such knowledge and experience in financial and business matters to enable Purchaser to utilize the information contained in the Disclosure Documents or otherwise made available to Purchaser to evaluate the merits and risks of an investment in the Shares and Warrants and to make an informed investment decision.

(g) Investment Intent. Purchaser is acquiring the Shares and Warrants solely for Purchaser’s own account and for investment purposes, and not with a view to, or for sale in connection with, any distribution of the Shares and Warrants other than pursuant to an effective registration statement under the Act or unless there is an exemption from such registration available for such offer, sale or transfer.

(h) Forward Looking Statements. Matters discussed in the Disclosure Documents include matters that may be considered “forward looking” statements within the meaning of Section 27(a) of the Act and Section 21(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which statements Purchaser acknowledges and agrees are not guarantees of future performance and involve a number of risks and uncertainties. Nothing contained in this Section 5(h) shall modify, amend or affect Purchaser’s right to rely on the truth, accuracy and completeness of the statements and representations made in the Disclosure Documents or otherwise communicated to Purchaser in writing by the Company or on the Company’s representations and warranties contained in this Agreement.

(i) No Assurance of Return on Investment. It has never been represented, guaranteed or warranted to Purchaser by the Company or any officer, director, employee, or agent of the Company, that Purchaser will realize any specific value, sale price, or profit as a result of acquiring the Shares and Warrants.

6. Stem Cell Transaction.

(a) Purchaser acknowledges receipt of copies of the draft agreements listed on Schedule I, which the Company represents are the most recent drafts as of the date hereof of the proposed agreements between or among the Company, BioTime or Geron relating to the Stem Cell Transaction.

(b) Upon completion of the Stem Cell Transaction, the Company alone or though one or more joint development, joint venture, or similar arrangements, will use the assets acquired from Geron pursuant thereto for research and development of products for commercialization, or will license assets to third parties for such purpose.

Resale Restrictions.

(a) Purchaser agrees that it will not sell, offer for sale, or transfer any of their Shares or Warrants unless those Shares or Warrants, as applicable, have been registered under the Act, or unless there is an exemption from such registration and an opinion of counsel reasonably acceptable to the Company has been rendered stating that such offer, sale, or transfer will not violate any United States federal or state securities laws.

(b) The certificates evidencing Shares or Warrants will contain a legend to the effect that transfer is prohibited except pursuant to registration under the Act, or pursuant to an available exemption from registration under the Act.

(c) The Company will refuse to register the transfer, and will issue instructions to the transfer agent and registrar of the Shares and Warrants to refuse to register the transfer, of any Shares or Warrants not made pursuant to registration under the Act or pursuant to an available exemption from registration under the Act.
