PROXY STATEMENT ANNUAL MEETING OF SHAREHOLDERS To Be Held on July 16, 1999

[PG NUMBER] The accompanying proxy is solicited by the Board of Directors of BioTime, Inc., a California corporation (the "Company" or "BioTime") having its principal offices at 935 Pardee Street, Berkeley, California 94710, for use at the Annual Meeting of Shareholders of the Company (the "Meeting") to be held at 10:00 a.m. on Friday, July 16, 1999 at the Radisson Hotel Berkeley Marina, 200 Marina Boulevard, Berkeley, California. Properly executed proxies in the accompanying form that are received at or before the Meeting will be voted in accordance with the directions noted on the proxies. If no direction is indicated, such shares will be voted FOR (1) each nominee for election as director, and (2) approval of the appointment of Deloitte & Touche LLP as independent accountants for the Company for the fiscal year ending December 31, 1999. (2) The enclosed proxy confers discretionary authority to vote with respect to any and all of the following matters that may come before the Meeting: matters that the Company's Board of Directors does not know a reasonable time before the Meeting are to be presented at the Meeting; and matters incidental to the conduct of the Meeting. Management does not intend to present any business for a vote at the Meeting other than the matters set forth in the accompanying Notice of Annual Meeting of Shareholders, and as of the date of this Proxy Statement, no shareholder has notified the Company of any other business that may properly come before the Meeting. If other matters requiring the vote of the shareholders properly come before the Meeting, then it is the intention of the persons named in the enclosed form of proxy to vote the proxy held by them in accordance with their judgment on such matters. Only shareholders of record at the close of business on June 4, 1999 are entitled to notice of and to vote at the Meeting. On that date, there were 10,819,733 of the Company's Common Shares issued and outstanding, which constitutes the only class of voting securities of the Company outstanding. Each of the Company's Common Shares is entitled to one vote in the election of directors and in all other matters that may be acted upon at the Meeting, except that shareholders may elect to cumulate votes in the election of directors. Under cumulative voting, each shareholder may give one candidate or may distribute among two or more candidates, a number of votes equal to the number of directors to be elected multiplied by the number of Common Shares owned. Shareholders may not cumulate votes unless at least one shareholder gives notice of his or her intention to cumulate votes at the Meeting. The enclosed proxy confers discretionary authority to cumulate votes. Any shareholder giving a proxy has the power to revoke that proxy at any time before it is voted. A proxy may be revoked by filing with the Secretary of the Company either a written revocation or a duly executed proxy bearing a date subsequent to the date of the proxy being revoked, or by voting in person at the Meeting. Any shareholder may attend the Meeting and vote in person, whether or not such shareholder has previously submitted a proxy, but attendance at the Meeting will not revoke a proxy unless the shareholder votes in person. The Company will bear all of the costs of the solicitation of proxies for use at the Meeting. In addition to the use of the mails, proxies may be solicited by a personal interview, telephone and telegram by directors, officers and employees of the Company, who will undertake such activities without additional compensation. Banks, brokerage houses and other institutions, nominees or fiduciaries will be requested to forward the proxy materials to the beneficial owners of the Common Shares held of record by such persons and entities and will be reimbursed for their reasonable expense incurred in connection with forwarding such material. This Proxy Statement and the accompanying form of proxy are first being sent or given to the Company's shareholders on or about June 10, 1999.

ELECTION OF DIRECTORS At the Meeting, eight directors will be elected to hold office for a one-year term until the 1999 Annual Meeting of Shareholders, and until their successors have been duly elected and qualified.

There are no family relationships among the directors or officers of the Company, except that Paul Segall and Judith Segall are husband and wife. Directors' Meetings, Compensation and Committees of the Board The Board of Directors has an Audit Committee, the members of which are Jeffrey Nickel and Milton Dresner. The purpose of the Audit Committee is to recommend the engagement of the Company's independent auditors and to review their performance, the plan, scope and results of the audit, and the fees paid to the independent auditors. The Audit Committee also will review the Company's accounting and financial reporting procedures and controls and all transactions between the Company and its officers, directors, and shareholders who beneficially own 5% or more of the Common Shares. The Company does not have a standing Nominating Committee. Nominees to the Board of Directors are selected by the entire Board. The Board of Directors has a Stock Option Committee that administers the Company's 1992 Stock Option Plan and makes grants of options to key employees, consultants, scientific advisory board members and independent contractors of the Company, but not to officers or directors of the Company. The members of the Stock Option Committee are Paul Segall, Ronald S. Barkin, and Victoria Bellport. The Stock Option Committee was formed during September 1992. During the fiscal year (six months) ended December 31, 1998, the Board of Directors met three times. No director attended fewer than 75% of the meetings of the Board or any committee on which they served. Directors of the Company who are not employees receive an annual fee of $20,000, which may be paid in cash or in Common Shares, at the election of the director. Directors may also receive grants of stock options under the Company's 1992 Stock Option Plan. Directors of the Company and members of committees of the Board of Directors who are employees of the Company are not compensated for serving as directors or attending meetings of the Board or committees of the Board. Directors are entitled to reimbursements for their out-of-pocket expenses incurred in attending meetings of the Board or committees of the Board. Directors who are employees of the Company are also entitled to receive compensation in such capacity. 3

Executive Compensation The Company has entered into five-year employment agreements (the "Employment Agreements") with Paul Segall, the Chairman and Chief Executive Officer; Victoria Bellport, the Chief Financial Officer; Judith Segall, Vice President of Technology and Corporate Secretary; Hal Sternberg, Vice President of Research; and Harold Waitz, Vice President of Engineering and Regulatory Affairs. The Employment Agreements will expire on December 31, 2000 but may terminate prior to the end of the term if the employee (1) dies, (2) leaves the Company, (3) becomes disabled for a period of 90 days in any 150 day period, or (4) is discharged by the Board of Directors for failure to carry out the reasonable policies of the Board, persistent absenteeism, or a material breach of a covenant. Under the Employment Agreements, as amended, the executive officers are presently receiving an annual salary of $156,000, and will receive a one-time cash bonus of $25,000 if the Company receives at least $1,000,000 of equity financing from a pharmaceutical company. In the event of the executive officer's death during the term of his or her Employment Agreement, the Company will pay his or her salary to his or her estate for a period of six months or until December 31, 2000, whichever first occurs. In the event that the executive officer's employment terminates, voluntarily or involuntarily, after a change in control of the Company through an acquisition of voting stock, an acquisition of the Company's assets, or a merger or consolidation of the Company with another corporation or entity, the executive officer will be entitled to severance compensation equal to the greater of (a) 2.99 times his or her average annual compensation for the preceding five years and (b) the balance of his or her base salary for the unexpired portion of the term of his Employment Agreement. The Company also entered into a similar Employment Agreement with Ronald S. Barkin, President of the Company. Mr. Barkin's Employment Agreement commenced on April 1, 1997 and expires on March 31, 2002. Each executive officer has also executed an Intellectual Property Agreement which provides that the Company is the owner of all inventions developed by the executive officer during the course of his or her employment. Insider Participation in Compensation Decisions The Board of Directors does not have a standing Compensation Committee. Instead, the Board of Directors as a whole approves all executive compensation. All of the executive officers of the Company serve on the Board of Directors but do not vote on matters pertaining to their own personal compensation. Paul Segall and Judith Segall do not vote on matters pertaining to each other's compensation. Board of Directors Report on Executive Compensation The compensation policies implemented by the Board of Directors have been influenced by the need to attract and retain executives with the scientific and management expertise to conduct the Company's product development program in a highly competitive industry dominated by larger, more highly capitalized companies. Executive compensation is also influenced by the cost of living in the San Francisco Bay Area. Executive compensation may be composed of three major components: (i) base salary; (ii) annual variable performance awards payable in cash and tied to the Company's attainment of corporate objectives and the officer's achievement of personal goals; and (iii) long-term stock-based incentive awards (stock options) designed to strengthen the mutuality of interests between the executive officers and the Company's shareholders. The Company entered into five-year employment agreements with each of its executive officers in order to assure that their services would continue to be available at a pre-determined base salary during a critical period in the 4

development of the Company's products and technology. The base salaries fixed by the Employment Agreements were raised during May 1999 to bring them within the median salary range for small to medium market capitalization biotechnology and drug development companies in the same geographic area as the Company. An annual bonus may be earned by each executive officer based upon the achievement of personal and Company performance goals. Because the Company is in the development stage, the use of performance milestones based upon profit levels and return on equity as the basis for such incentive compensation is not considered appropriate. Instead, the incentive awards have been tied to the achievement of personal and corporate performance targets. The Company performance goals vary from year to year according to the stage of the Company's operations. Important milestones that have been considered by the Board of Directors in determining incentive bonuses have been (i) procurement of additional capital, (ii) licensing Company products, (iii) completing specified research and development goals, and (iv) achievement of certain organizational goals. Personal goals are related to the functional responsibility of each executive officer. The Board of Directors as a whole determines whether or not each Company performance goal has been achieved. During the fiscal year ended December 31, 1998 (six months), the Board of Directors did not award any cash bonuses or grant any stock options to the executive officers. The following table summarizes certain information concerning the compensation paid to the Company's five most highly compensated executive officers during the last three fiscal years.

Stock Options None of the Company's five most highly compensated executive officers exercised any stock options or held any unexercised options during the fiscal year ended December 31, 1998. Certain Relationships and Related Transactions During the six months ended December 31, 1998, $6,119 in fees for consulting services was paid to Jeffrey B. Nickel, a member of the Board of Directors. During September 1995, the Company entered into an agreement for financial advisory services with Greenbelt Corp., a corporation controlled by Alfred D. Kingsley and Gary K. Duberstein. Under this agreement the Company issued to the financial advisor warrants to purchase 311,276 Common Shares at a price of $1.93 per share, and the Company agreed to issue additional warrants to purchase up to an additional 622,549 Common Shares at a price equal to the greater of (a) 150% of the average market price of the Common Shares during the three months prior to issuance and (b) $2 per share. The additional warrants were issued in equal quarterly installments over a two year period, beginning October 15, 1995. The exercise price and number of Common Shares for which the warrants may be exercised are subject to adjustment to prevent dilution in the event of a stock split, combination, stock dividend, reclassification of shares, sale of assets, merger or similar transaction. The warrants are exercisable at the following prices: 466,912 at $1.93 per share; 77,818 at $2.35 per share; 77,818 at $9.65 per share; 77,818 at $9.42 per share; 77,818 at $10.49 per share; 77,818 at $15.74 per share; and 77,818 at $13.75 per share. The number of shares and exercises prices shown have been adjusted for the Company's subscription rights distributions during January 1997 and February 1999 and the payment of a stock dividend during October 1997. Under the agreement, upon the request of Greenbelt Corp., the Company will file a registration statement to register the warrants and underlying Common Shares for sale under the Securities Act of 1933, as amended (the "Act") and applicable state securities or "Blue Sky" laws. The Company will bear the expenses of registration, other than any underwriting discounts that may be incurred by Greenbelt Corp. in connection with a sale of the warrants or Common Shares. The Company is not obligated to file more than two such registration statements, other than registration statements on Form S-3. Greenbelt Corp. also is entitled to include warrants and Common Shares in any registration statement filed by the Company to register other securities for sale under the Act. During April 1998, the Company entered into a new financial advisory services agreement with Greenbelt Corp. The new agreement provides for an initial payment of $90,000 followed by an advisory fee of $15,000 per month that will be paid quarterly. The agreement will expire on March 31, 2000, but either party may terminate the agreement earlier upon 30 days prior written notice. The Company has agreed to reimburse Greenbelt Corp. for all reasonable out-of-pocket expenses incurred in connection with its engagement as financial advisor, and to indemnify Greenbelt Corp. and the officers, affiliates, employees, agents, assignees, and controlling person of Greenbelt Corp. from any liabilities arising out of or in connection with actions taken on behalf of the Company under the agreement. Comparison of Shareholder Return The graph depicted below reflects a comparison of the cumulative total return (change in stock price plus reinvestment of dividends) of the Company's Common Shares with the cumulative total returns of the Nasdaq Stock Market Index, the BioCentury 100 Stock Index, and the Hambrecht & Quist Biotechnology Index. The BioCentury 100 Stock Index includes many companies in an early stage of development that have a market capitalization similar to BioTime's. The graph 6

covers the period from July 1, 1993, the first day of the Company's fifth preceding fiscal year, through the fiscal year ended December 31, 1998. [Graph] The graph assumes that $100 was invested on July 1, 1993 in the Company's Common Shares and in each index and that all dividends were reinvested. No cash dividends have been declared on the Company's Common Shares.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934 Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), requires the Company's directors and executive officers and persons who own more than ten percent (10%) of a registered class of the Company's equity securities to file with the Securities and Exchange Commission (the "SEC") initial reports of ownership and reports of changes in ownership of Common Shares and other equity securities of the Company. Officers, directors and greater than ten percent beneficial owners are required by SEC regulation to furnish the Company with copies of all reports they file under Section 16(a). To the Company's knowledge, based solely on its review of the copies of such reports furnished to the Company and written representations that no other reports were required, all Section 16(a) filing requirements applicable to its officers, directors and greater than ten percent beneficial owners were complied with during the fiscal year ended December 31, 1998.

HOW TO ATTEND THE ANNUAL MEETING If you are a "shareholder of record" (meaning that you have a stock certificate registered in your own name), your name will appear on the Company's shareholder list. You will be admitted to the Meeting upon showing your proxy card, driver's license, or other identification. If you are a "street name" shareholder (meaning that your shares are held in account at a broker-dealer firm) your name will not appear on the Company's shareholder list. If you plan to attend the Meeting, you should ask your broker for a "legal proxy." You will be admitted to the Meeting by showing your legal proxy. You probably received a proxy form from your broker along with your proxy statement, but that form can only be used by your broker to vote your shares, and it is not a "legal proxy" that will permit you to vote your shares directly at the Meeting. If you cannot obtain a legal proxy in time, you will be admitted to the Meeting if you bring a copy of your most recent brokerage account statement showing that you own BioTime stock. However, if you do not obtain a legal proxy, you can only vote your shares by returning to your broker, before the Meeting, the proxy form that accompanied your proxy statement.
