This Agreement is entered into by BioTime, Inc. (“Subscriber”) and OncoCyte Corporation, a California corporation (the “Company).

(c)            Payment.  Subscriber shall pay the Subscription Price of the Shares by check for good funds payable to the order of the Company or by wire transfer to such account of the Company as the Company may specify.  If this Agreement is rejected or not accepted for any reason by the Company, all sums paid by the Subscriber will be promptly returned, without interest or deduction.







(d)            Acceptance of Subscriptions.  The Company may accept subscriptions in the Subscription Offer at any time on or after receipt until the Expiration Date.







3.                   Registration Rights.

4.                   Investment Representations.  Subscriber represents and warrants to the Company that:







(a)            Due Diligence. Subscriber has made such investigation of the Company as Subscriber deemed appropriate for determining to acquire (and thereby make an investment in) the Shares.  In making such investigation, Subscriber has had access to such financial and other information concerning the Company as Subscriber requested.  Subscriber acknowledges and understands that the Company is an early stage venture engaged in research and development, without only limited history of operations, and has received only limited capital.  Subscriber acknowledges receipt of the Articles of Incorporation and Bylaws of the Company, and such copies of the minutes of the proceedings of the Board of Directors of the Company as Subscriber may have requested from the Company.  Subscriber 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 such additional information concerning the Company as may have been possessed or obtainable by the Company without unreasonable effort or expense. All such questions have been answered to Subscriber’s satisfaction.







(b)            Unregistered Offer and Sale. Subscriber understands that the Shares are being offered and sold without registration under the Securities Act, or qualification under the California Corporate Securities Law of 1968, or under the laws of any other states, in reliance upon the exemptions from such registration and qualification requirements for non-public offerings.  Subscriber 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 Subscriber, and the information provided by Subscriber, in this Agreement,  Subscriber 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 Subscriber’s suitability to acquire the Shares.  Subscriber understands and acknowledges that no federal, state or other agency has reviewed or endorsed the offering of the Shares or made any finding or determination as to the fairness of the offering or completeness of the information provided to Subscriber by the Company.








2










(c)            Restrictions on Transfer. Subscriber understands that the Shares may not be offered, sold, or transferred in any manner unless subsequently registered under the Securities Act, or unless there is an exemption from such registration available for such offer, sale or transfer.  Subscriber agrees that Subscriber will not sell, offer for sale, or transfer any of the Shares unless those Shares have been registered under the Securities 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.  Subscriber acknowledges that (i) the certificates evidencing the Shares will contain a legend to the effect that transfer is prohibited except pursuant to registration under the Securities Act, or pursuant to an available exemption from registration under the Securities Act, and (ii) The Company will refuse to register the transfer, and will issue instructions to any transfer agent and registrar of the Shares to refuse to register the transfer, of any Shares not made pursuant to registration under the Securities Act or pursuant to an available exemption from registration under the Securities Act.







(d)            Knowledge and Experience. Subscriber has such knowledge and experience in financial and business matters to enable Subscriber to utilize the information provided or otherwise made available to Subscriber by the Company to evaluate the merits and risks of an investment in the Shares and to make an informed investment decision.







(e)            Investment Intent.  Subscriber is acquiring the Shares solely for Subscriber’s own account and for investment purposes, and not with a view to, or for sale in connection with, any distribution of the Shares other than pursuant to an effective registration statement under the Securities Act or unless there is an exemption from such registration available for such offer, sale or transfer, such as SEC Rule 144.







(f)            Forward Looking Statements.  Information provided to Subscriber by the Company include matters that may be considered “forward looking” statements within the meaning of Section 27(a) of the Securities Act and Section 21(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which statements Subscriber acknowledges and agrees are not guarantees of future performance and involve a number of risks and uncertainties, and with respect to which the Company makes no representations or warranties.  Subscriber understands that the level of disclosure provided by the Company is less than that which would be provided in a securities offering registered under the Securities Act in reliance on the sophistication and investment experience of Subscriber.







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








3










(h)            Nonpublic Information.  Subscriber understands that (1) this Agreement and other information provided to Subscriber by the Company contains confidential financial information about the Company and BioTime, Inc. that has not yet been publicly disclosed by the Company or BioTime, and therefore may be deemed material non-public information, (2) the Company is providing Subscriber the confidential information solely to satisfy its disclosure obligations under the Securities Act in connection with the offer and sale of the Shares to Subscriber pursuant to this Agreement, and (3) until such time as BioTime files a Form 8-K or other report under the Exchange Act with the Securities and Exchange Commission, Subscriber shall not (A) disclose to any other person any of the information contained in this Agreement or otherwise provided to Subscriber concerning the Company that has not previously been disclosed in a report filed by BioTime under the Exchange Act, or (B) purchase or sell any common shares of BioTime.







(i)            Authority; Enforceability.  The Subscriber has the power and authority to execute and deliver, and to perform all of Subscriber’s obligations under, this Agreement.  This Agreement has been duly executed and delivered by Subscriber.  This Agreement is the valid and binding agreements of the Subscriber, 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.







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