ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

On April 12, 2006, BioTime entered into a Revolving Line of Credit Agreement (the “Credit Agreement”) with Alfred D. Kingsley, Cyndel & Co., Inc., and George Karfunkel, investors in BioTime, under which BioTime may borrow up to $500,000 for working capital purposes at an interest rate of 10% per annum. The credit line will expire, and any funds borrowed must be repaid, on the earlier of October 31, 2007 or when BioTime receives $600,000 in new funding through the sale of capital stock, the receipt of licensing and similar fees in excess of $1,000,000, from other borrowing, or any combination of those sources. Under the Credit Agreement, BioTime will prepay, and the credit line will be reduced by, any funds received prior to the maturity date from those sources. In consideration for making the line of credit available, BioTime issued to the investors a total of 100,000 common shares. The line of credit is collateralized by a security interest in BioTime’s right to receive royalty and other payments under its license agreement with Hospira, Inc. Mr. Kingsley has agreed to lend BioTime up to $166,666.67, and he will receive 33,333 Shares, under the Credit Agreement.

From March 26, 2006 through April 1, 2006, warrants entitling Mr. Kingsley to purchase 193,798 shares at prices above the then current market price expired unexercised.

During April 2006, Greenbelt entered into a one year extension of its Financial Adviser Agreement with BioTime, pursuant to which Greenbelt will be entitled to receive a cash fee of $90,000 and 200,000 Shares (the “2006 Consulting Shares”) for services rendered. The 2006 Consulting Shares will be issued in two installments as follows: 150,000 Shares on January 2, 2007 for services rendered through December 31, 2006, and 50,000 Shares on April 2, 2007 for services rendered from January 1, 2007 through March 31, 2007. BioTime has agreed to file a registration statement, at BioTime’s expense, to register the 2006 Consulting Shares for sale under the Securities Act of 1933, as amended, upon Greenbelt’s request.

Attention: Judith Segall, Vice President-Operations

 
RE:
Financial Adviser Agreement

Dear Judith:

This letter sets forth the terms on which the letter agreement between BioTime, Inc. (“BioTime”) and Greenbelt Corp. (“Financial Adviser”), dated April 30, 1998, as amended, (the “Agreement”) shall be extended and modified.

1. Expiration Date. The term of the Agreement will continue in effect from April 1, 2006 through March 31, 2007.

2. Compensation. BioTime agrees to pay Greenbelt (a) a cash fee of $90,000, and (b) 200,000 common shares. The shares shall be issued as follows: 150,000 shares on January 2, 2007 for services rendered through December 31, 2006, and 50,000 shares on April 2, 2007 for services rendered from January 1, 2007 through March 31, 2007. The cash fee shall be due and payable as follows: $30,000 on January 2, 2007, $30,000 on April 2, 2007, and $30,000 on October 1, 2007; provided, that BioTime may defer either or both of the cash payments that would otherwise be due on January 2, 2007 and April 2, 2007 until a date that BioTime may determine, but not later than October 1, 2007. If BioTime elects to so defer a cash payment for a period of more than five business days, BioTime shall issue to Greenbelt 30,000 additional common shares within ten business days after the date on which the deferred cash payment was originally due. In the event that the Agreement is terminated by either party and such termination takes effect on a date other than the last day of a calendar quarter, the amount of cash and number of Shares issuable with respect to the calendar quarter will be pro rated, to the nearest whole Share, by multiplying the amount of cash payable and Shares issuable for that quarter by a fraction the numerator of which is the number of days that have elapsed from the first day of the calendar quarter through the date of termination, and the denominator of which is the number of days in the calendar quarter. Payment of any prorated amount shall be due on the next proceeding date for payment under this paragraph, subject to the right of BioTime to defer the cash payment as provided in this paragraph.

3. Investment Representations. Financial Adviser represents and warrants to BioTime that:

(a) Financial Adviser has received and read a draft of BioTime’s Quarterly Report on Form 10-QSB for the three months ended March 31, 2006 and BioTime’s Annual Report on Form 10-K for the year ended December 31, 2005, including the risks described in the “Risk Factors” section, and all Current Reports on Form 8-K filed by BioTime since January 1, 2006 (collectively, the “SEC Filings”). Financial Adviser is relying on the information provided in the SEC Filings or otherwise communicated to Financial Adviser in writing by BioTime. Financial Adviser has not relied on any statement or representations inconsistent with those contained in the SEC Filings. Financial Adviser has had a reasonable opportunity to ask questions of and receive answers from the executive officers and directors of BioTime, or one or more of its officers, concerning BioTime and to obtain additional information, to the extent possessed or obtainable without unreasonable effort or expense, necessary to verify the information in the SEC Filings. All such questions have been answered to Financial Adviser’s satisfaction;

(b) Financial Adviser understands that the Shares are being offered and sold without registration under the Securities Act of 1933 (the “1933 Act”) or qualification under the California Corporate Securities Law of 1968, or under the laws of other states, in reliance upon the exemptions from such registration and qualification requirements for non-public offerings. Financial Adviser acknowledges and understands that the availability of the aforesaid exemptions depends in part upon the accuracy of certain of the representations, declarations and warranties contained herein, which Financial Adviser hereby makes with the intent that they may be relied upon by BioTime and its officers and directors in determining Financial Adviser’s suitability to purchase the Shares. Financial Adviser 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 in the SEC Filings;

(c) Financial Adviser understands that the Shares may not be offered, sold, or transferred in any manner, unless subsequently registered under the 1933 Act, or unless there is an exemption from such registration and an opinion of counsel for BioTime has been rendered stating that such offer or transfer will not violate any federal or state securities laws;

(d) Financial Adviser understands and agrees that all certificates evidencing the Shares shall bear an appropriate legend to the effect that the securities have not been registered under the 1933 Act and may not be sold or transferred in the absence of such registration or an exemption therefrom.

(e) Financial Adviser has such knowledge and experience in financial and business matters to enable it to utilize the information contained in the SEC Filings, or otherwise made available to Financial Adviser to evaluate the merits and risks of an investment in the Shares and to make an informed investment decision with respect thereto.

2

(f) Financial Adviser is purchasing the Shares solely for Financial Adviser’s own account and for long-term investment purposes, and not with a view to, or for sale in connection with, any distribution of the Shares; and

(g) Financial Adviser is an “accredited investor,” as such term is defined in Regulation D promulgated under the 1933 Act. 

4. Registration Rights. 

(a) BioTime agrees, at its expense, upon written request from the Financial Adviser, to use commercially reasonable efforts to register under the 1933 Act the Shares and to take such other actions as may be necessary to allow the Shares to be freely tradable, without restrictions, in compliance with all regulatory requirements. A written request for registration shall specify the quantity of the Shares intended to be sold, the plan of distribution and the identity of the sellers, which may include the Financial Adviser and assignees of its rights hereunder (collectively, “Selling Securities Holders”), and whether the registration shall be pursuant to an underwritten public offering or a “shelf” registration pursuant to Rule 415 (or similar rule that may be adopted by the Securities and Exchange Commission). BioTime shall not be obligated to file more than two such registration statements, other than registration statements on Form S-3. BioTime shall use commercially reasonable efforts keep such registration statements effective for a period of at least nine months, except that registration statements on Form S-3 shall be kept effective for at least three years (or such lesser period as the parties may agree, but in no event beyond the completion of the distribution or distributions being made pursuant thereto). BioTime shall utilize Form S-3 if it qualifies for such use. BioTime shall make all filings required with respect to the registration statements and will use commercially reasonable efforts to cause such filings to become effective, so that the Shares being registered shall be registered or qualified for sale under the securities or blue sky laws of such jurisdictions as shall be reasonably appropriate for distribution of the Shares covered by the registration statement. BioTime shall have no obligation to make any cash settlement or payment to the Financial Adviser or any Selling Securities Holders or to issue any additional Shares in the event that BioTime is unable to effect or maintain in effect the registration of the Shares under the 1933 Act or any state securities law despite BioTime’s commercially reasonable efforts so to do.

BioTime will furnish to the Selling Securities Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the 1933 Act and such other related documents as the Selling Securities Holders may reasonably request in order to effect the sale of the Shares. To effect any offering pursuant to a registration statement under this Section, BioTime shall enter into an agreement containing customary representations and warranties, and indemnification and contribution provisions, all for the benefit of Selling Securities Holders, and, in the case of an Underwritten public offering, an underwriting agreement with an investment banking firm selected by the Financial Adviser and reasonably acceptable to BioTime, containing such customary representations and warranties, and indemnification and contribution provisions

(b) If, at any time, Bio Time proposes to register any of its securities under the 1933 Act (otherwise than pursuant to paragraph 4(a) above or on a Form S-8 if such form cannot be used for registration of the Shares pursuant to its terms), BioTime shall, as promptly as practicable, give written notice to the Financial Adviser. BioTime shall include in such registration statement any Shares proposed to be sold by the Selling Securities Holders. Notwithstanding the foregoing, if the offering of BioTime’s securities is to be made through underwriters, BioTime shall not be required to include Shares if and to the extent that the managing underwriter reasonably believes in good faith that such inclusion would materially adversely affect such offering unless the Selling Securities Holders agree to postpone their sales until 10 days after the distribution is completed.

(c) BioTime shall pay the cost of the registration statements filed pursuant to this Agreement, including without limitation all registration and filing fees, fees and expenses of compliance with securities or blue sky laws (including counsel’s fees and expenses in connection therewith), printing expenses, messenger and delivery expenses, internal expenses of BioTime, listing fees and expenses, and fees and expenses of BioTime’s counsel, independent accountants and other persons retained or employed by BioTime. Selling Securities Holders shall pay any underwriters discounts applicable to Shares.

(d) BioTime agrees that upon the sale of Shares pursuant to a registration statement or an exemption, upon the presentation of the certificates containing such legend to its transfer agent, it will remove such legend. BioTime further agrees to remove the legend at such time as registration under the 1933 Act shall no longer be required.

5.  Other Provisions. Except as expressly modified by this letter, all terms and provisions of the Agreement shall remain in effect.
