                                PROXY STATEMENT


                        ANNUAL MEETING OF SHAREHOLDERS

                        To Be Held on October 28, 2002

     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  Monday,  October  28,  2002  at the Courtyard by Marriott, 5555
Shellmound  Street,  Emeryville,  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,  (2)  approval  of the 2002 Stock Option Plan, and (3) approval of the
appointment  of Deloitte & Touche LLP as independent accountants for the Company
for the fiscal year ending December 31, 2002.

     The  enclosed proxy confers discretionary authority to vote with respect to
any  and  all  of  the  following  matters that may come before the Meeting: (1)
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 (2) 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 attached 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 Friday, September
20,  2002  are  entitled  to notice of and to vote at the Meeting. On that date,
there  were  13,490,101  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 September 27, 2002.




                             ELECTION OF DIRECTORS

     At  the  Meeting,  eight  directors  will  be  elected to hold office for a
one-year  term  until  the  2003 Annual Meeting of Shareholders, and until their
successors  have  been  duly  elected  and  qualified. All of the nominees named
below  are  incumbent  directors  except  Michael D. West. Since the last annual
meeting  of  shareholders,  Ronald S. Barkin retired as President of the Company
and  from  the  Board  of Directors, after more than eleven years of service. We
all thank Ron for his dedication and hard work.

     It  is  the  intention  of  the persons named in the enclosed proxy, unless
such  proxy  specifies  otherwise,  to vote the shares represented by such proxy
FOR  the  election  of the nominees listed below. In the unlikely event that any

Directors' Meetings, Compensation and Committees of the Board

     The  Board  of  Directors  has an Audit Committee, the members of which are
Jeffrey  Nickel,  Milton Dresner, and Katherine Gordon. 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 Company's independent auditors. More information about the
Audit  Committee  can  be  found  in  the  "Audit  Committee  Report." 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  2002  Stock Option Plan and makes grants of options to key employees,
consultants,  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,  Hal Sternberg and Jeffrey Nickel. The Stock Option Committee was formed
during September 1992.

     During  the fiscal year ended December 31, 2001, the Board of Directors met
eight  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 received an annual fee of
$20,000  during  2001. Directors were given the choice of receiving their fee in
cash  or  Common  Shares  of an equivalent market value. Milton Dresner received
3,224  Common  Shares in lieu of the cash fee during the year ended December 31,
2001.  During  the  year  ended  December  31,  2001,  Katherine Gordon received
options  to purchase 15,000 Common Shares, and Jeffrey Nickel and Milton Dresner
each  received  options  to  purchase  10,000  Common  Shares.  Directors of the
Company  and  members  of committees of the Board of Directors who are employees
of the Company are

                                       3


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.

     For  2002,  the  non-employee Directors received 20,000 options exercisable
at  $3.00  per  share,  which  was  the  closing  price for BioTime stock on the
American  Stock  Exchange  on the last day of March, 2002. During this year, the
Directors  will  not  receive  cash  fees. Of the 20,000 options granted, 12,500
were  fully  vested  and  exercisable  upon grant and the remaining 7500 options
were   scheduled   to   vest  and  become  exercisable  in  nine  equal  monthly
installments  based  on continued service on the Board of Directors. If elected,
Mr.  West  will  receive 18,332 options of which 15,000 will be fully vested and
the  remaining  3,332  options will vest in two equal monthly installments based
on continued service on the Board of Directors.

Audit Committee Report

     The   Audit  Committee  is  composed  of  three  independent  directors  in
accordance   with   Section  121(A)  of  the  American  Stock  Exchange  listing
standards.  The  Audit Committee operates under a written charter adopted by the
Board  of Directors. A copy of the Audit Committee Charter is available from the
Company upon request.

     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 Company's independent
auditors.  The  Audit  Committee  also  reviews  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  independent  public  accountants  are  responsible  for  performing an
independent  audit  of  the  Company's  consolidated  financial  statements  and
issuing  an opinion on the conformity of those audited financial statements with
generally accepted accounting principles.

     During  the  last  year,  the  Audit Committee has met three times and held
discussions  with  management and representatives of Deloitte & Touche, LLP, the
Company's  independent auditors. The Audit Committee reviewed and discussed with
Company  management  and  representatives  of  Deloitte  &  Touche  the  audited
financial  statements  contained in the Company's Annual Report on Form 10-K for
the  year  ended  December  31,  2001.  The  Audit Committee also discussed with
Deloitte  & Touche the matters required to be discussed by Statement on Auditing
Standards  No.  61  (Communications  with  Audit  Committees). Deloitte & Touche
submitted  to  the  Audit  Committee  the  written  disclosures  and  the letter
required   by   Independence   Standards  Board  Standard  No.  1  (Independence
Discussions  with  Audit  Committees).  Based  on  the  reviews  and discussions
referred  to  above, the members of the Audit Committee unanimously approved the
inclusion  of the audited financial statements in the Company's Annual Report on
Form  10-K  for  the year ended December 31, 2001, filed with the Securities and
Exchange Commission.

     Audit  Fees. Deloitte & Touche billed the Company $110,619 for professional
services  rendered  for  the audit of the Company's annual financial statements,
and  for review of the financial statements included in the Company's Forms 10-Q
for the last fiscal year.

     Other  Fees. Deloitte  & Touche billed the Company $15,451 for professional
services  rendered  other  than  the audit and review of the Company's financial
statements  for  the  last  fiscal  year.  Deloitte & Touche did not provide any
financial  information  system design or implementation services during the last
fiscal  year.  The  Audit  Committee  believes  that the payment of such fees is
consistent  with  the  maintenance  of  the independence of Deloitte & Touche as
independent auditors.

     The  Audit  Committee:  Jeffrey B. Nickel, Milton H. Dresner, and Katherine
Gordon.

              Board of Directors Report on Executive Compensation

     The  Board  of  Directors  does not have a standing Compensation Committee.
Instead,  the Board of Directors as a whole approves all executive compensation.
The  executive  officers  of  the Company who serve on the Board of Directors 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.

     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.  These  factors  have  been balanced against the
Company's  financial  position and capital resources. 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.

     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 was
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, 2001, the Board of Directors did not
award any cash bonuses or grant any stock options to the executive officers.

     During  2001,  the Company implemented a salary reduction program to reduce
costs.  Most of the executive officers participated in the program. The Board of
Directors  has approved a continuation of those reduced salaries until the Board
of  Director determines that the Company is in a financial position to commit to
other  compensation arrangements commensurate with each officer's experience and
past  performance  and  prevailing  compensation  rates in the San Francisco Bay
area.

     The  Board  of  Directors: Paul Segall, Hal Sternberg, Harold Waitz, Judith
Segall, Jeffrey B. Nickel, Milton H. Dresner, and Katherine Gordon.

Executive Compensation

     The  Company had five-year employment agreements with Paul Segall, Chairman
and  Chief  Executive  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 that expired on
December  31,  2000  and were renewed for a one-year term that ended on December
31,  2001.  The  Company also had an employment agreement with Ronald S. Barkin,

Certain Relationships and Related Transactions

     During  September 1995, the Company entered into an agreement for financial
advisory  services  with Greenbelt Corp. ("Greenbelt"), a corporation controlled
by  Alfred  D. Kingsley and Gary K. Duberstein, who are also shareholders of the
Company.  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  number  of shares and exercise 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. Greenbelt has
purchased  544,730  Common Shares by exercising some of those warrants at prices
ranging  from  $1.93  to  $2.35  per  share.  The  other  warrants  have expired
unexercised.

     During  April  1998,  the  Company  entered  into  a new financial advisory
services  agreement  with  Greenbelt.  The new agreement provided for an initial
payment  of  $90,000  followed  by  an  advisory  fee  of $15,000 per month paid
quarterly.  The Company agreed to reimburse Greenbelt for all reasonable out-of-
pocket  expenses  incurred  in  connection  with  its  engagement  as  financial
advisor,  and  to  indemnify  Greenbelt and its officers, affiliates, employees,
agents,  assignees,  and  controlling person from any liabilities arising out of
or  in  connection  with  actions taken on BioTime's behalf under the agreement.
The  agreement  has  been renewed three times and will expire on March 31, 2002.
The  Company  agreed  to  issue Greenbelt 30,000 Common Shares in four quarterly
installments  of  7,500  shares each for the twelve months ended March 31, 2001,
40,000  Common  Shares  in  four  quarterly  installments of 10,000 each for the
twelve  months  ended  March  31,  2002,  and $60,000 in cash and 100,000 Common
Shares  in four quarterly installments of $15,000 cash and 25,000 shares for the
twelve months ending March 31, 2003.

     During  March  2001,  the  Company  entered into a Line of Credit Agreement
with  Alfred  D.  Kingsley  under  which Mr. Kingsley agreed to lend the Company
$1,000,000.  In  consideration  of Mr. Kingsley's agreement to provide that line
of  credit, the Company issued to him a warrant to purchase 50,000 Common Shares
at  an exercise price of $8.31 per share. The warrant will expire in five years.
The  exercise  price  and  number  of Common Shares for which the warrant 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.

     During  August  2001,  the Company received loans of $3,350,000 through the
sale  of debentures to a group of private investors, including Mr. Kingsley, who
purchased  $1,500,000  of  debentures,  and  Milton  Dresner,  a director of the
Company.  Mr.  Kingsley's  investment  included the conversion of the $1,000,000
principal balance of the line of credit that he had previously provided.

     Interest  on  the  debentures  is  payable  at an annual rate of 10% and is
payable  semiannually.  The  principal  amount of the debentures will be due and
payable  on  August  1,  2004. BioTime may prepay the debentures, in whole or in
part,  at  any  time  without  premium  or  penalty.  Under  the  terms  of  the
debentures,  BioTime has agreed that commencing October 1, 2001 it will restrict
its  quarterly  cash  payments  for operating expenses to not more than $450,000
(excluding  interest payable on the debentures) plus the amount of cash revenues
(excluding  interest  and  dividends) it collects for the quarter. To the extent
BioTime's  expenditures  during  any  quarter  are  less  than $450,000 over its
revenues,  it may expend the difference in one or more subsequent quarters. That
restriction  will  expire  when  BioTime  obtains  at  least  $5,000,000 in cash
through

                                       7



sales  of  equity securities or pays off the debenture indebtedness in full. For
this  purpose,  cash  revenues  will  include royalties, license fees, and other
proceeds  from  the  sale  or licensing of its products and technology, but will
not  include  interest,  dividends, and any monies borrowed or the proceeds from
the  issue or sale of any debt or equity securities. BioTime has also agreed not
to  declare  or  pay  any  cash  dividends  on its capital stock or to redeem or
repurchase  any shares of its capital stock, until it has paid off the debenture
indebtedness in full.

     Investors  who  purchased the debentures also received warrants to purchase
a  total  of  515,383 common shares at an exercise price of $6.50 per share. The
warrants  will  expire  if  not exercised by August 1, 2004. The Company has the
right  to  call  the  warrants for redemption at a redemption price of $0.01 per
share  if the closing price of the Company's Common Shares on the American Stock
Exchange  equals  or  exceeds  150%  of  the  exercise  price  for  fifteen (15)
consecutive  trading  days  and  the  shares  issuable  upon the exercise of the
warrants  have  been  registered  for  sale under the Securities Act of 1933, as
amended (the "Act").

     During  March  2002,  the  Company entered into a new Credit Agreement with
Alfred  D.  Kingsley  for  a  $300,000  line  of credit. In consideration of Mr.
Kingsley's  agreement  to provide that line of credit, the Company issued to him
a  warrant  to  purchase  30,000 Common Shares at an exercise price of $4.00 per
share.  The  warrant will expire in five years. The exercise price and number of
Common  Shares  for which the warrant 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.

     During  August  2002, the Company sold 1,852,785 Common Shares at $1.12 per
share  in  a private placement. Mr. Kingsley purchased 89,285 Common Shares, and
Jeffrey  Nickel purchased 10,000 Common Shares, from the Company in that private
placement at the same price and on the same terms as the other investors.

     The  Company has registered for sale under the Act, the warrants and Common
Shares  described  above,  including  Common  Shares that may be issued upon the
exercise  of  the  warrants  or  in  installments  under  the financial advisory
agreement,  other  than the shares issuable under the current financial advisory
agreement  which may be registered at a later date. The Company also included in
the  registration  300,000  Common  Shares  that  Mr.  Kingsley  acquired during
December  2000 from certain BioTime officers and directors. The Company pays the
expenses  of  registration,  but  will  not be obligated to pay any underwriting
discounts  or  commissions  that may be incurred by Greenbelt, Mr. Kingsley, Mr.
Dresner,  or  Mr.  Nickel  in connection with any sale of the warrants or Common
Shares.

     On  July  3,  2002  Paul  Segall  and Harold Waitz each sold 200,000 Common
Shares  to  Mr.  Kingsley  at  a  price  of  $2.00 per share to eliminate margin
indebtedness.  Also  on  July  3, 2002, Mr. Kingsley made unsecured loans in the
amounts of $220,000 to Dr. Segall and $252,000 to Dr. Waitz.

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,  and  the  BioCentury  100  Stock  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 covers the period from June 30,
1996 through the fiscal year ended December 31, 2001.


                               [GRAPHIC OMITTED]


     The  graph  assumes that $100 was invested on July 1, 1996 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, 2001, except that
Steven  Seinberg,  Chief  Financial  Officer,  was late in filing a Form 3 and a
Form 4.

                      APPROVAL OF 2002 STOCK OPTION PLAN

     The  Company  is  asking the shareholders to approve the BioTime 2002 Stock
Option  Plan  (the  "2002  Plan")  which  was  adopted by the Board of Directors
during  September  2002 to replace the Company's original stock option plan that
was  adopted  during 1992 and has now expired (the "1992 Plan"). Approval of the
2002  Plan  requires  the affirmative vote of a majority of the shares attending
the  Meeting.  Unless  otherwise  directed  by the shareholders, proxies will be
voted FOR approval of the 2002 Plan.

                 The Board of Directors Recommends a Vote "FOR"
                    Approval of the 2002 Stock Option Plan

Reasons for Adopting the 2002 Plan

     Stock  options are an important part of employee compensation packages. The
Board  of  Directors strongly believes that the Company's ability to attract and
retain  the  services of employees and consultants depends in great measure upon
its  ability  to  provide  the  kind  of  incentives  that  are derived from the
ownership   of   stock   and  stock  options  and  that  are  offered  by  other
pharmaceutical  development  companies.  This is especially true for the Company
since  the  salaries  it  pays  its  employees  are  lower than the compensation
packages  offered by competing companies. The Board believes the Company will be
placed  at  a  serious  competitive  disadvantage  in  attracting  and retaining
capable  employees and consultants at a critical time in its development, unless
the 2002 Plan is approved by the shareholders.

     The  following  summary  of  the  2002 Plan is qualified in all respects by
reference  to  the full text of the 2002 Plan which is attached as an Exhibit to
this Proxy Statement.

The 1992 Plan

     The  following  table  shows  certain  information  concerning  the options
outstanding  and  available  for issuance under the 1992 Plan as of December 31,
2001. The Company had no other equity compensation plans in effect.

Plans Approved by
Shareholders


     Since  December  31,  2001,  the  Company  has granted an additional 60,000
options  and  368,201  remain outstanding under the 1992 Plan. The 1992 Plan has
expired  and no additional options may be granted under it. However, outstanding
stock  options  granted  under  the  1992  Plan  will remain in effect until the
expiration date specified in those options.

Administration of the 2002 Plan

     The  2002  Plan  is  administered  by the Board of Directors (the "Board"),
which  determines  which  officers,  employees, consultants, scientific advisory
board  members  and  independent  contractors  of  the Company are to be granted
options,  the  number  of  shares  subject  to the options granted, the exercise
price  of the options, and certain other terms and conditions of the options. No
options  may  be  granted under the 2002 Plan more than ten years after the date
the  2002  Plan  was adopted by the Board, and no options granted under the 2002
Plan  may be exercised after the expiration of ten years from the date of grant.
The  Board  may delegate administration of the 2002 Plan, including the power to
grant  options to persons who are not officers or directors of the Company, to a
Stock Option Committee (the "Committee") of the Board.

Shares Available Under the 2002 Plan

     The  Company  has  reserved 1,000,000 Common Shares under the 2002 Plan for
issuance under options or restricted stock purchase agreements.

Options Granted

     The  Board  of Directors or the Option Committee have approved the grant of
options  to  purchase  445,000  Common Shares under the 2002 Plan effective upon
shareholder  approval  of  the  2002  Plan,  including  395,000  incentive stock
options  granted  to  executive  officers  and  directors  of  the  Company,  as
illustrated  in the following table. These options will vest, and thereby become
exercisable  in  three installments, as follows: one-third on the effective date
of  grant,  one-third  on January 1, 2003, and one-third on January 1, 2004, and
will  expire five years after the effective date of the grant (which will be the
date  of  the  Annual  Meeting if the shareholders approve the 2002 Plan at that
Meeting).  These  options  have  been granted subject to shareholder approval of
the 2002 Plan.

Judith Segall               80,000                 $4.00           5 years
Steven Seinberg             20,000                 $4.00           5 years

     In  granting  options  to  the  Company's  executive officers, the Board of
Directors  considered  their past performance, number of years of service to the
Company,  current  compensation, and the number of options previously granted to
them  under  the 1992 Plan. Dr. Segall is presently receiving a salary of $3,000
per  month  and  Drs.  Sternberg  and Waitz and Judith Segall are each presently
receiving  a  salary of $6,000 per month, and Mr. Seinberg is receiving a salary
of  $ 6,792  per  month.  None  of  the  executive  officers presently holds any
options  granted  under the 1992 Plan, except for Mr. Seinberg who holds options
to  purchase a total of 24,000 shares at prices ranging from $18.25 to $4.80 per
share.  Messrs.  Segall,  Sternberg and Waitz have not received options from the
Company  since  1992, when they received options to purchase 63,000 shares each.
Judith  Segall  has never received any stock options from the Company during her
nearly 12 years of service.

Terms of the Options

     Options  granted  under  the  2002  Plan  may  be  either  "incentive stock
options"  within  the  meaning of Section 422(b) of the Internal Revenue Code of
1986,  as  amended (the "Code"), or non-qualified stock options. Incentive stock
options  may  be  granted  only to employees of the Company or its subsidiaries.
The  exercise  price of incentive stock options granted under the 2002 Plan must
be  equal  to  the  fair  market  of the Company's Common Shares on the date the
option  is  granted.  In the case of an optionee who, at the time of grant, owns
more  than  10%  of  the  combined  voting  power of all classes of stock of the
Company,  the exercise price of any incentive stock option must be at least 110%
of  the  fair  market value of the Common Shares on the grant date, and the term
of  the option may be no longer than five years. The aggregate fair market value
of  the  Common  Shares  (determined  as  of  the grant date of the option) with
respect  to  which incentive stock options become exercisable for the first time
by an optionee in any calendar year may not exceed $100,000.

     The  options  exercise  price  may  be  payable in cash or in Common Shares
having  a  fair market value equal to the exercise price, or in a combination of
cash and Common Shares.

     Options  granted under the 2002 Plan are nontransferable (except by will or
the  laws  of  descent  and  distribution)  and  may  vest  in  annual  or other
installments.  Incentive  stock  options may be exercised only during employment
or  within three months after termination of such employment, subject to certain
exceptions in the event of the death or disability of the optionee.

Certain Adjustments to Number of Shares and Exercise Price

     The  number  of  Common  Shares covered by the 2002 Plan, and the number of
Common  Shares and exercise price per share of each outstanding option, shall be
proportionately  adjusted  for  any increase or decrease in the number of issued
and  outstanding  Common Shares resulting from a subdivision or consolidation of
shares  or the payment of a stock dividend, or any other increase or decrease in
the  number  of issued and outstanding Common Shares effected without receipt of
consideration by the Company.

Corporate Reorganization or Liquidation

     In  the  event  of the dissolution or liquidation of the Company, or in the
event  of  a  reorganization, merger or consolidation of the Company as a result
of which the Common Shares are


                                       13


changed  into  or  exchanged  for  cash  or  property  or  securities not of the
Company's  issue,  or  upon  a  sale  of  substantially  all the property of the
Company  to,  or  the acquisition of stock representing more than eighty percent
80%  of  the  voting  power  of  the  stock  of the Company then outstanding by,
another  corporation  or person, the 2002 Plan and all options granted under the
2002  Plan  shall  terminate,  unless  provision  can  be  made  in  writing  in
connection  with  such  transaction  for either the continuance of the 2002 Plan
and/or  for  the  assumption  of  options  granted  under  the 2002 Plan, or the
substitution  for  such  options  by  options  covering the stock of a successor
corporation,  or  a  parent  or  a  subsidiary  of a successor corporation, with
appropriate adjustments as to the number and kind of shares and prices.

Restricted Stock Sales

     In  lieu  of  granting options, the Company may enter into restricted stock
purchase  agreements  with employees under which they may purchase common shares
subject  to  certain  vesting  and  repurchase restrictions. The Company has the
right  to  repurchase  unvested  shares  at  the  shareholder's  cost  upon  the
occurrence  of specified events, such as termination of employment. The price at
which  shares may be sold under restricted stock purchase agreements will be not
less  than 85% of fair market value, or 100% of fair market value in the case of
stock  sold to a person who owns capital stock representing more than 10% of the
combined  voting  power  of  all classes of the Company's stock. The Company may
permit  employees  or  consultants, but not executive officers or directors, who
purchase  stock  under  restricted  stock  purchase  agreements to pay for their
shares  by  delivering  a  promissory  note that is secured by a pledge of their
shares.

          FEDERAL INCOME TAX CONSEQUENCE OF PARTICIPATION IN THE PLAN

     The   following   discussion   summarizes   certain   federal   income  tax
consequences  of  participation  in the 2002 Plan. Although the Company believes
the  following  statements  are correct based on existing provisions of the Code
and  the  regulations  thereunder,  the  Code or regulations may be amended from
time  to  time,  and  future judicial interpretations may effect the veracity of
the discussion.

Incentive Stock Options

     Under  Section  422(a)  of the Code, the grant and exercise of an incentive
stock  option  pursuant  to the 2002 Plan is entitled to the benefits of Section
421(a)  of  the  Code. Under Section 421(a), an optionee will not be required to
recognize  income at the time the option is granted or at the time the option is
exercised,  except to the extent that the optionee is subject to the alternative
minimum  tax.  If  the  applicable holding periods described below are met, when
the  shares  of  stock  received  upon exercise of an incentive stock option are
sold  or  otherwise disposed of in a taxable transaction, the option holder will
recognize  compensation  income  (taxed  as  a  long term capital gain), for the
taxable  year  in  which disposition occurs, in an amount equal to the excess of
the  fair market value of the Common Shares at the time of such disposition over
the amount paid for the shares.

     The  Company  will  not  be entitled to any business expense deduction with
respect  to  the  grant  or  exercise  of  an  incentive stock option, except in
connection  with  a  disqualifying disposition as discussed below. No portion of
the  amount  received  by  the  optionee upon the sale of Common Shares acquired
through   the  exercise  of  an  incentive  stock  option  will  be  subject  to
withholding  for federal income taxes, or be subject to FICA or state disability
taxes, except in connection with a disqualifying disposition.

     In  order for a participant to receive the favorable tax treatment provided
in  Section  421(a)  of the Code, Section 422 requires that the participant make
no  disposition  of  the option shares within two years from the date the option
was granted, nor within one year from the date such

                                       14


option  was  exercised  and  the  shares were transferred to the participant. In
addition,   the   participant   must,  with  certain  exceptions  for  death  or
disability,  be  an employee of the Company (or of a parent or subsidiary of the
Company,  as defined in Section 424(e) and (f) of the Code, or a corporation, or
parent  or  subsidiary  thereof,  issuing  or assuming the option in a merger or
other  corporate  reorganization transaction to which Section 424(a) of the Code
applies)  at  all  times within the period beginning on the date of the grant of
the  option  and  ending  on  a  date  within  three  months  before the date of
exercise.  In  the  event  of  the death of the participant, the holding periods
will  not  apply  to  a  disposition  of  the  option  or  option  shares by the
participant's  estate  or  by  persons  receiving the option or shares under the
participant's will or by intestate succession.

     If  a participant disposes of stock acquired pursuant to the exercise of an
incentive  stock option before the expiration of the holding period requirements
set  forth  above, the participant will realize, at the time of the disposition,
ordinary  income to the extent the fair market value of the Common Shares on the
date  the  shares  were  purchased  exceeded  the purchase price. The difference
between  the  fair market value of the Common Shares on the date the shares were
purchased  and  the  amount  realized  on disposition is treated as long-term or
short-term  capital  gain or loss, depending on the participant's holding period
of  the  Common  Shares. The amount treated as ordinary income may be subject to
the  income  tax  withholding  requirements  of  the  Code  and FICA withholding
requirements.  The participant will be required to reimburse the Company, either
directly  or  through  payroll  deduction,  for  all  withholding taxes that the
Company  is  required  to  pay  on behalf of the participant. At the time of the
disposition,  the  Company  will  be  allowed  a  corresponding business expense
deduction  under  Section  162  of  the  Code to the extent of the amount of the
participant's  ordinary income. The Company may adopt procedures to assist it in
identifying  such  deductions,  and  may  require  a  participant  to notify the
Company of his or her intention to dispose of any such shares.

Other Options

     The  2002  Plan  also  permits  the  Company  to  grant options that do not
qualify  as  incentive stock options. These "non-qualified" stock options may be
granted  to  employees  or  non-employees,  such  as  members  of  the Company's
scientific   advisory   board   and   other  persons  performing  consulting  or
professional  services  for  the Company. A 2002 Plan participant who receives a
non-qualified  option  will  not  be taxed at the time of receipt of the option,
provided  that  the  option  does  not  have  an  ascertainable  value,  but the
participant will be taxed at the time the option is exercised.

     The  amount  of  taxable  income  that  will  be  earned upon exercise of a
non-qualified  option  will  be  the difference between the fair market value of
the  Common  Shares  on  the  date of the exercise and the exercise price of the
option.  The  Company will be allowed a business expense deduction to the extent
of  the  amount of the participant's taxable income recognized upon the exercise
of  a  non-qualified  option.  Because  the  option  holder  is  subject  to tax
immediately  upon  exercise  of  the  option,  there  are  no applicable holding
periods  for  the  stock.  The  option  holder's  tax basis in the Common Shares
purchased  through  the  exercise of a non-qualified option will be equal to the
exercise  price  paid  for  the stock plus the amount of taxable gain recognized
upon  the exercise of the option. The option holder may be subject to additional
tax on sale of the stock if the price realized exceeds his or her tax basis.

Restricted Stock Purchase Agreements

     An  employee  or  consultant  who purchases shares under a restricted stock
purchase  agreement  at  fair  market value will not incur any income tax at the
time  of the purchase. Instead, the employee or consultant will incur income tax
when  the  shares  are  sold  in a taxable transaction. The tax incurred will be
either a long term if the shares have been held for at least one year, or

                                       15


a  short  term  capital gain if the shares are sold before the expiration of the
one  year  holding  period. Employees who purchase shares under restricted stock
purchase  agreements rather than through the exercise of incentive stock options
will  not  be subject to the alternative minimum tax as a result of the purchase
of the shares.

ERISA

     The  2002  Plan is not subject to the provisions of the Employee Retirement
Income  Security  Act  of  1974,  as  amended,  and  is not qualified under Code
Section 401(a).

           RATIFICATION OF THE SELECTION OF INDEPENDENT ACCOUNTANTS

     The  Board  of  Directors  proposes  and  recommends  that the shareholders
ratify  the  selection  of  the  firm  of  Deloitte  &  Touche  LLP  to serve as
independent  accountants  of the Company for the fiscal year ending December 31,
2002.  Deloitte & Touche LLP has served as the Company's independent accountants
since  1991.  Unless  otherwise  directed  by  the shareholders, proxies will be
voted  FOR  approval  of  the  selection  of  Deloitte & Touche LLP to audit the
Company's  consolidated  financial  statements.  A  representative of Deloitte &
Touche  LLP  will  attend  the  Meeting,  and will have an opportunity to make a
statement  if he or she so desires and may respond to appropriate questions from
shareholders.

The  Board of Directors Recommends a Vote "FOR" Ratification of the Selection of
        Deloitte & Touche LLP as the Company's Independent Accountants

                           PROPOSALS OF SHAREHOLDERS

     Shareholders  of the Company who intend to present a proposal for action at
the  2003  Annual  Meeting  of  Shareholders  of  the  Company  must  notify the
Company's  management  of  such  intention  by  notice received at the Company's
principal  executive  offices not later than March 31, 2003 for such proposal to
be  included in the Company's proxy statement and form of proxy relating to such
meeting.

                                 ANNUAL REPORT

     The  Company's  Annual  Report  on  Form 10-K filed with the Securities and
Exchange  Commission  for  the  fiscal  year  ended  December  31, 2001, without
exhibits,  may be obtained by a shareholder without charge, upon written request
to the Secretary of the Company.

                       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  an  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.

                                   ARTICLE I
                                    GENERAL


     1. PURPOSE

     This  BioTime,  Inc. Stock Option Plan (the "Plan") is intended to increase
incentive  and  to  encourage  stock  ownership  on  the  part  of  selected key
officers,   directors,   employees,   consultants,   professionals,   and  other
individuals  whose  efforts may aid BioTime, Inc., a California corporation (the
"Company")  or  any other corporations that are or which may become subsidiaries
or  a  parent  of  the  Company.  Except  where  the  context obviously requires
otherwise,  as  used  in this Plan, the term "Company" includes BioTime, Inc., a
California  corporation,  and  any  corporation  that  is or becomes a parent or
subsidiary,  as  defined in Section 425 of the Internal Revenue Code of 1986, as
amended  (the  "Code"),  of  BioTime,  Inc.  It is intended that certain options
granted  pursuant  to  the  Plan shall constitute incentive stock options within
the  meaning  of  Section  422(b)  of  the  Code  and that certain other options
granted  pursuant  to  the  Plan  shall  not  constitute incentive stock options
("nonqualified stock options").

     2. ADMINISTRATION

     The  Plan  shall  be  administered by the Company's Board of Directors (the
"Board")  or,  in  the discretion of the Board, by a committee (the "Committee")
of  not  less  than two members of the Board. The Committee's interpretation and
construction  of  any  term  or  provision  of the Plan or of any option granted
under  the  Plan  shall  be  final, unless otherwise determined by the Board, in
which  event  such  determination by the Board shall be final. The Committee may
from  time  to  time adopt rules and regulations for carrying out this Plan and,
subject  to  the provisions of this Plan, may prescribe the form or forms of the
instruments  evidencing  any  option  granted  under this Plan. No member of the
Committee  shall  be  liable  for any action or determination made in good faith
with  respect  to  the Plan or any option granted, or with respect to any shares
sold under any restricted stock purchase agreement, under the Plan.

     Subject  to  the  provisions of this Plan, the Board or the Committee shall
have  full  and final authority in its discretion to select the eligible persons
to  whom  options are granted or shares are sold under restricted stock purchase
agreements,  to  grant such options and to sell shares as provided in this Plan,
to  determine  the number of shares to be subject to options or sold pursuant to
restricted  stock  purchase  agreements,  to  determine  the  exercise prices of
options   or   purchase   prices  of  shares  under  restricted  stock  purchase
agreements,  the  terms of exercise of options, expiration dates of options, and
other  pertinent  terms  and provisions of options and restricted stock purchase
agreements.  The  Board  may  delegate  to  the  Committee the power to make all
determinations  with  respect to the Plan, or may delegate to the Committee only
certain  aspects  of Plan administration, such as selecting the eligible persons
to  whom  options  will be granted, or decisions concerning the timing, pricing,
and  amount  of  a  grant or award of options or sale of shares under restricted
stock purchase agreements.

     3. ELIGIBILITY

     Subject  to  Section 2 of this Article I, the persons who shall be eligible
to  receive  options  or  to  purchase  shares  under  restricted stock purchase
agreements  under  the  Plan  shall  be  such  officers,  employees,  directors,
consultants,  professionals,  and  independent contractors of the Company as the
Board of Directors or the Committee may select. Eligible persons who are not


                                       A-1


also   salaried   employees   of  the  Company  shall  be  eligible  to  receive
nonqualified  stock  options  (but such persons shall not be eligible to receive
incentive stock options).

     4. SHARES OF STOCK SUBJECT TO THE PLAN

     The  shares  that  may  be  issued  under  the Plan shall be authorized and
unissued  or  reacquired  common  shares,  no  par  value,  of  the Company (the
"Shares").  The  aggregate  number  of Shares which may be issued under the Plan
shall  not exceed 1,000,000, unless an adjustment is required in accordance with
Article III.

     5. AMENDMENT OF THE PLAN

     The  Board  may, insofar as permitted by law, from time to time, suspend or
discontinue  the  Plan  or  revise or amend it in any respect whatsoever, except
that  no  such  amendment  shall  alter  or  impair  or  diminish  any rights or
obligations  under  any option theretofore granted or under any restricted stock
purchase  agreement  executed  under the Plan, without the consent of the person
to  whom  such option was granted or Shares were sold, except as permitted under
Section  8  of  this  Article  I.  Without further shareholder approval, no such
amendment  shall  increase  the  number of shares subject to the Plan (except as
authorized  by Article III), change the designation in Section 3 of Article I of
the  class  of  persons eligible to receive options or purchase Shares under the
Plan,  extend  the  term  during  which  options may be exercised, or extend the
final  date  upon  which  options under the Plan may be granted or Shares may be
sold under restricted stock purchase agreements.

     6. APPROVAL OF SHAREHOLDERS

     All  options  granted  under  the  Plan  before  the  Plan  is  approved by
affirmative  vote  of  the  holders  of  a  majority of the voting shares of the
Company  present and eligible to vote at the next meeting of shareholders of the
Company,  or  any  adjournment  thereof,  shall  be subject to such approval. No
option  granted  hereunder may become exercisable unless and until such approval
is obtained.

     7. TERM OF PLAN

     Options  may  be  granted  and  Shares  may  be sold under restricted stock
purchase  agreements  under  the  Plan  until  September  10,  2012, the date of
termination  of  the  Plan.  Notwithstanding  the foregoing, each option granted
under  the  Plan  shall remain in effect until such option has been exercised or
terminated in accordance with its terms and the terms of the Plan.

     8. LISTING, REGISTRATION, QUALIFICATION, AND CONSENTS

     All  options  granted  under  the  Plan shall be subject to the requirement
that,  if  at  any  time  the  Board  or  the  Committee shall determine, in its
discretion,  that  the  listing,  registration  or  qualification  of the shares
subject  to  options  granted  under  the  Plan, upon any securities exchange or
under  any  state  or  federal law, or the consent or approval of any government
regulatory  body,  is necessary or desirable as a condition of, or in connection
with,  the  granting  of  such  option  or  the issuance, if any, or purchase of
shares  in connection therewith, such option may not be exercised in whole or in
part  unless  such  listing,  registration,  qualification,  consent or approval
shall  have  been  effected or obtained free of any conditions not acceptable to
the  Board  or  the  Committee.  Furthermore,  if  the  Board  or  the Committee
determines  that  any amendment to any option (including, but not limited to, an
increase  in  the  exercise  price) is necessary or desirable in connection with
the  registration  or  qualification  of  any  of  its  shares  under  any state
securities  or  "blue  sky"  law, then the Board or the Committee shall have the
unilateral right to make such changes without the consent of the optionee.


                                       A-2


     9. NONASSIGNABILITY

     Nonqualified  options  shall  be  transferable  (i) by will, by the laws of
descent  and distribution, by instrument to an inter vivos or testamentary trust
in  which  the  nonqualified  options are to be passed to beneficiaries upon the
death  of the optionee or (ii) to the extent and in the manner authorized by the
Board  or  Committee  by  gift  to  members  of the optionee's immediate family.
Immediate  family means a transferee as permitted by Rule 260.140.41 of Title 10
of  the  California  Code  of  Regulations  which includes any child, stepchild,
grandchild,  parent,  stepparent,  grandparent,  spouse, sibling, mother-in-law,
father-in-law,  son-in-law,  daughter-in-law,  brother-in-law,  or sister-in-law
and  shall  also include adoptive relationships. Incentive stock options may not
be  sold,  pledged,  assigned,  hypothecated, transferred, or disposed of in any
manner  other  than by will or by the laws of descent or distribution and may be
exercised,   during  the  lifetime  of  the  optionee,  only  by  the  optionee.
Notwithstanding  the  preceding  two sentences, in conjunction with the exercise
of  an option, and for the purpose of obtaining financing for such exercise, the
option  holder  may arrange for a securities broker/dealer to exercise an option
on  the option holder's behalf, to the extent necessary to obtain funds required
to pay the exercise price of the option.

     10. WITHHOLDING TAXES

     Whenever  Shares are to be issued upon the exercise of any option under the
Plan  or  under  any restricted stock purchase agreement, the Company shall have
the  right  to  require  the  optionee  or  purchaser to remit to the Company an
amount   sufficient  to  satisfy  federal,  state,  and  local  withholding  tax
requirements  prior  to the delivery of any certificate or certificates for such
Shares.

     11. DEFINITION OF "FAIR MARKET VALUE"

     For  the  purposes of this Plan, the term "fair market value," when used in
reference  to  the date of grant of an option or the date of surrender of Shares
in  payment  for  the purchase of Shares pursuant to the exercise of any option,
as  the  case  may  be,  shall  mean  the  amount determined by the Board or the
Committee as follows:

       (a) If  the  Shares  are  listed or have unlisted trading privileges on a
national  securities  exchange  (which  for the purposes of this Plan shall also
include  the Nasdaq Stock Market National Market), the Shares shall be valued at
their  last  sale  price on the principal national securities exchange (measured
by  volume  of  transactions in such Shares) on which such securities shall have
traded,  or,  if  available, such sales price as reported on the composite tape,
on the last trading day immediately preceding the date of grant or surrender.

       (b) If  the  Shares are described in either subparagraph (a) or (b) above
but  were  not  traded on the last trading day immediately preceding the date of
grant  or  surrender,  or  if  prices  of  the Shares are quoted in the National
Association  of  Securities Dealers, Inc., Automated Quotation system (but which
not  the  National  Market  System), or if prices of the Shares are published by
the  National  Quotation  Bureau,  Inc.,  then the Shares shall be valued at the
average  between  the  last  bid  and the last asked prices reported in the Wall
Street  Journal or published by the National Quotation Bureau within the 30 days
prior to the date of grant or surrender.

       (c) If  the  Shares  are  not described in and valued under subparagraphs
(a)  and  (b)  above,  then  the  Shares  shall  be  valued  by the Board or the
Committee, in its sole judgement, in good faith.


                                       A-3


                                  ARTICLE II
                                 STOCK OPTIONS


     1. AWARD OF STOCK OPTIONS

     Awards  of stock options may be made under the Plan under all the terms and
conditions  contained  herein.  However, in the case of incentive stock options,
the  aggregate  fair  market  value  (determined  as of the date of grant of the
option)  of  the  Shares  with  respect  to  which  incentive  stock options are
exercisable  for  the  first  time  by  such  officer or key employee during any
calendar  year (under all incentive stock option plans of the Company) shall not
exceed  $100,000.  The  date on which any option is granted shall be the date of
the  Board's  or  the Committee's authorization of such grant or such later date
as  may  be  determined  by the Board or the Committee at the time such grant is
authorized.

     2. TERM OF OPTIONS AND EFFECT OF TERMINATION

     Notwithstanding  any  other  provision  of the Plan, an option shall not be
exercisable  after  the expiration of ten (10) years from the date of its grant.
In  addition,  notwithstanding  any  other  provision  of the Plan, no incentive
stock  option granted under the Plan to a person who, at the time such option is
granted,  owns  shares  possessing  more  than  10% of the total combined voting
power  of  all  classes  of shares of the Company or of any parent or subsidiary
corporation,  shall  be  exercisable after the expiration of five (5) years from
the date of its grant.

     In  the  event that any outstanding option under the Plan expires by reason
of  lapse  of  time  or otherwise is terminated or canceled for any reason, then
the  Shares  subject  to  any such option which have not been issued pursuant to
the  exercise  of  the option shall again become available in the pool of Shares
for which options may be granted under the Plan.

     3. CANCELLATION OF AND SUBSTITUTION FOR OPTIONS

     The  Company  shall  have the right to cancel any option at any time before
it  otherwise  would have expired by its terms and to grant to the same optionee
in  substitution  therefor  a  new stock option stating an option price which is
lower  (but not higher) than the option price stated in the canceled option. Any
such  substituted  option  shall  contain  all  the  terms and conditions of the
canceled  option  provided,  however,  that notwithstanding Section 2 of Article
II,  such  substituted  option  shall not be exercisable after the expiration of
ten (10) years from the date of grant of the canceled option.

     4. TERMS AND CONDITIONS OF OPTIONS

     Options  granted  pursuant  to the Plan shall be evidenced by agreements in
such  form  as  the  Board  or  the Committee shall from time to time determine,
which agreements shall comply with the following terms and conditions.

       (a) Number of Shares and Type of Option

       Each  option  agreement  shall  state  the number of Shares for which the
option  is  exercisable  and  whether  the option is intended to be an incentive
stock option or a nonqualified stock option.

       (b) Option Price

       Each  option  agreement  shall  state the exercise price per share or the
method  by  which  such  price  shall  be computed. The exercise price per share
shall  be  determined  by  the Board or the Committee at the date such option is
granted.  In  the  case  of a nonqualified option, the exercise price may be not
less  than 85% of the fair market value of the Shares on the date such option is
granted.  In  the case of an incentive stock option, the exercise price shall be
not less

                                      A-4


than  100%  of  the  fair  market value of the Shares on the date such option is
granted.  Notwithstanding  the  foregoing,  the  exercise  price  per share of a
option  granted  to  a  person  who, on the date of such grant and in accordance
with  Section  425(d)  of  the Code, owns shares possessing more than 10% of the
total  combined  voting  power of all classes of shares of the Company or of any
parent  or  subsidiary  corporation,  shall  be  not  less than 110% of the fair
market value of the Shares on the date that the option is granted.

       (c) Medium and Time of Payment

       The  exercise  price  shall  be payable upon the exercise of an option in
the  lawful  currency  of  the United States of America or, in the discretion of
the  Board  or the Committee, in Shares or in a combination of such currency and
such  Shares. Upon receipt of payment, the Company shall deliver to the optionee
(or  person  entitled  to exercise the option) a certificate or certificates for
the Shares purchased through such exercise.

       (d) Exercise of Options

       Options   granted   under   the  Plan  shall  vest,  and  thereby  become
exercisable,  at  the  time  or  times,  or  upon the happening of the events or
circumstances,  determined by the Board or the Committee. All options granted to
employees  who  are not officers, directors, or consultants shall vest at a rate
not  less  than 20% per year over 5 years from the date of sale. Options granted
to  officers,  directors,  and  consultants may vest at any time or from time to
time  upon  the  satisfaction  of reasonable conditions to vesting determined by
the  Board  or  Committee.  Without  limiting the other events and circumstances
upon  which  vesting  may be determined, the Board or Committee may make vesting
conditioned  upon  continued  employment  by  the Company. The terms under which
options  shall  vest  shall be stated in each option agreement. The Board or the
Committee  may,  in  its  discretion, accelerate (but not delay or postpone) the
time or times at which an option vests.

       To  the  extent  that  an option has become vested (except as provided in
Article  III), and subject to the foregoing restrictions, it may be exercised in
whole  or in such lesser amount as may be authorized by the option agreement. If
exercised  in  part,  the  unexercised portion of an option shall continue to be
held by the optionee and may thereafter be exercised as herein provided.

       (e) Termination of Employment Except By Disability or Death

       In  the  event  that  an optionee who is an employee of the Company shall
cease  to  be employed by the Company for any reason other than his or her death
or  disability,  his  or her option shall terminate on the date (3) months after
the  date  that he ceases to be an employee of the Company. The Committee or the
Board  may  waive the provisions of this Subsection 4(e) at the date of grant of
an option or at a later date.

       (f) Disability of Optionee

       If  an  optionee  who  is  an  employee  of the Company shall cease to be
employed  by  the Company by reason of his or her becoming disabled, such option
shall  terminate  on  the date one (1) year after cessation of employment due to
such  disability.  Disability  means that an employee is unable to carry out the
responsibilities  and  functions  of the position held by the employee by reason
of  any  medically  determinable physical or mental impairment. The Committee or
the  Board may waive the provisions of this Subsection 4(f) at the time of grant
of  an option or at a later date if the option is not an incentive stock option.

       (g) Death of Optionee and Transfer of Option

       If  an  optionee should die while in the employ of the Company, or within
the  three-month  period  after  termination  of  his or her employment with the
Company during which he or

                                      A-5


she  is  permitted  to  exercise an option in accordance with Subsection 4(f) of
this  Article II, such option shall terminate on the date one (1) year after the
optionee's  death. During such one- year period, such option may be exercised by
the  executors  or  administrators  of the optionee's estate or by any person or
persons  who shall have acquired the option directly from the optionee by his or
her  will  or  the  applicable  law of descent and distribution. During such one
year  period,  such option may be exercised with respect to the number of Shares
for  which  the deceased optionee would have been entitled to exercise it at the
time  of  his  or her death. The Committee or the Board may waive the provisions
of  this Subsection 4(g) at the date of grant of an option or at a later date if
the option is not an incentive stock option.

                                  ARTICLE III
                     RECAPITALIZATIONS AND REORGANIZATIONS

     The  number  of  Shares  covered  by the Plan, and the number of Shares and
price  per  share  of each outstanding option, shall be proportionately adjusted
for  any  increase  or  decrease  in the number of issued and outstanding Shares
resulting  from  a  subdivision  or  consolidation of Shares or the payment of a
stock  dividend,  or  any other increase or decrease in the number of issued and
outstanding Shares effected without receipt of consideration by the Company.

     Upon   the   dissolution   or   liquidation  of  the  Company,  or  upon  a
reorganization,  merger or consolidation of the Company as a result of which the
outstanding  securities  of  the  class  then  subject  to options hereunder are
changed  into  or  exchanged  for  cash  or  property  or  securities not of the
Company's  issue,  or  upon  a  sale  of  substantially  all the property of the
Company  to,  or the acquisition of shares representing more than eighty percent
(80%)  of  the  voting  power  of the shares of the Company then outstanding by,
another  corporation  or  person,  the  Plan  shall  terminate,  and all options
theretofore  granted  hereunder shall terminate, unless provision can be made in
writing  in  connection  with  such  transaction for the continuance of the Plan
and/or  for  the  assumption of options theretofore granted, or the substitution
for  such  options of options covering the shares of a successor corporation, or
a  parent or a subsidiary thereof, with appropriate adjustments as to the number
and  kind  of shares and prices, in which event the Plan and options theretofore
granted shall continue in the manner and under the terms so provided.

     To   the  extent  that  the  foregoing  adjustments  relate  to  shares  or
securities  of  the  Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive.

     The  grant  of  an  option pursuant to the Plan shall not affect in any way
the  right  or  power  of  the  Company  to make adjustments, reclassifications,
reorganizations  or  changes or its capital or business structure or to merge or
to  consolidate  or  to dissolve, liquidate or sell, or transfer all or any part
of its business or assets.

                                  ARTICLE IV
             SALE OF RESTRICTED STOCK IN LIEU OF GRANT OF OPTIONS

       (a) Number of Shares

       Each  restricted  stock  purchase  agreement  shall  state  the number of
Shares sold under such agreement.

       (b) Purchase Price

       Each  restricted  stock purchase agreement shall state the purchase price
per  Share  or  the  method  by which such price shall be computed. The Purchase
price  per  Share  shall be determined by the Board or the Committee at the date
the  sale  of  the  Shares  is approved (the "Approval Date"); provided that the
purchase price per Share may be not less than 85% of the

                                      A-6



fair  market  value  per  Share  on the Approval Date and that if the restricted
shares  are  sold  to  an  individual who owns shares representing more than ten
percent  of  the  voting  power  of all classes of shares of the Company (or any
parent  or  subsidiary  of the Company), the purchase price per Share may not be
less than 100% of the fair market value per Share on the Approval Date.

       (c) Medium and Time of Payment

       The  purchase  price  shall  be  payable at the time the restricted stock
purchase  agreement is executed by the eligible person. Payment shall be made in
the  lawful  currency  of  the United States of America or, in the discretion of
the  Board  or  the  Committee,  by delivery of a promissory note payable to the
Company  in  such  lawful  currency.  Upon receipt of payment, the Company shall
deliver  to  the  eligible  person  a certificate or certificates for the Shares
purchased.

       (d) Repurchase Option

       Each  restricted  stock purchase agreement shall provide that the Company
shall  have the option to repurchase the Shares sold under such agreement in the
event  the  purchaser  ceases to be a full time employee of the Company prior to
the  vesting  of  such  Shares,  or if any other condition to the vesting of the
Shares  stated  in  the  restricted  stock  purchase  agreement  is not met (the
"Repurchase  Option").  The  Repurchase  Option  may be exercised by the Company
during  such  period  as  specified  in the applicable restricted stock purchase
agreement.  The  price  at  which the Company may repurchase the Shares upon the
exercise  of  the  Repurchase Option shall be the price at which the Shares were
sold  to  the  eligible  person,  or  such  greater  price  as  provided  in the
applicable  restricted  stock  purchase  agreement  approved by the Board or the
Committee.  If  the  purchaser  of  Shares  under  a  restricted  stock purchase
agreement  has  delivered  a  promissory  note  as payment of all or part of the
purchase  price  of  his  or  her  Shares,  the Company may cancel or reduce the
principal  balance  and  interest  accrued on that promissory note as payment of
all or part of the repurchase price upon exercise of the Repurchase Option.

       (e) Vesting of Shares.

       Shares  sold  pursuant  to  a  restricted  stock purchase agreement shall
vest,  and  thereby cease to be subject to the Repurchase Option, at the time or
times,  or  upon the happening of the events or circumstances, determined by the
Board  or  the  Committee.  All  Shares  sold to employees who are not officers,
directors,  or  consultants shall vest at a rate not less than 20% per year over
5  years  from  the  date  of  sale.  Shares  sold  to  officers, directors, and
consultants  may  vest at any time or from time to time upon the satisfaction of
reasonable  conditions  to vesting determined by the Board or Committee. Without
limiting   the  other  events  and  circumstances  upon  which  vesting  may  be
determined,  the  Board or Committee may make vesting conditioned upon continued
employment  by  the  Company.  The  terms under which Shares shall vest shall be
stated  in  the  restricted stock purchase agreement. The Board or the Committee
may,  in  its  discretion,  accelerate  (but  not delay or postpone) the time or
times at which Shares vest under a restricted stock purchase agreement.

     2. Escrow of Unvested Shares.

     The  Company  may  require  that  all  Shares sold under a restricted stock
purchase  agreement  be  held  in  escrow, on terms satisfactory to the Company,
until  such  Shares  have  vested  and have been paid for in full (including the
payment  of any amount due on any promissory note delivered by the purchaser and
secured by such Shares).


                                      A-7


     3. Legend  on  Stock  Certificates.  Shares issued under a restricted stock
purchase  agreement  shall  include,  in addition to any other legends as may be
required  by law or by the Board or Committee, a legend to the following effect:

      THESE  SHARES  MAY  BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
      AGREEMENT  BETWEEN  THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON
      FILE WITH THE SECRETARY OF THE COMPANY.

                                   ARTICLE V
                           MISCELLANEOUS PROVISIONS

     1. RIGHTS AS A STOCKHOLDER

     An  optionee  or  a  transferee  of  an  option  shall  have no rights as a
shareholder  with  respect  to any Shares covered by an option until the date of
the  receipt  of payment (including any amounts required by the Company pursuant
to  Section  10  of Article I) by the Company. No adjustment shall be made as to
any   option   for  dividends  (ordinary  or  extraordinary,  whether  in  cash,
securities  or  other  property)  or distributions or other rights for which the
record date is prior to such date, except as provided in Article III.

     2. MODIFICATION,  EXTENSION  AND  RENEWAL  OF  OPTIONS AND RESTRICTED STOCK
PURCHASE AGREEMENTS

     Subject  to  the  terms  and  conditions  and within the limitations of the
Plan,  the  Board  or  the  Committee  may  modify,  extend,  renew,  or  cancel
outstanding  options  granted  under  the  Plan  and  restricted  stock purchase
agreements.  Notwithstanding  the  foregoing,  however,  no  modification  of an
option  or restricted stock purchase agreement shall, without the consent of the
optionee  or  purchaser,  impair or diminish any rights or obligations under any
option  theretofore granted o restricted stock purchase agreement executed under
the  Plan,  except  as  provided  in Section 8 of Article I. For purposes of the
preceding  sentence,  the  right of the Company pursuant to Section 3 of Article
II  to  cancel  any  outstanding  option  and to issue in place of such canceled
option  a substituted option stating a lower option price shall not be construed
as impairing or diminishing an optionee's rights or obligations.

     3. OTHER PROVISIONS

     The  option  agreements and restricted stock purchase agreements authorized
under   the  Plan  shall  contain  such  other  provisions,  including,  without
limitation,  restrictions upon the exercise of the option or purchase of Shares,
or  restrictions required by any applicable securities laws, as the Board or the
Committee shall deem advisable.

     4. APPLICATION OF FUNDS

     The  proceeds  received  by the Company from the sale of Shares pursuant to
the  exercise  of  options or under restricted stock purchase agreements will be
used for general corporate purposes.

     5. NO OBLIGATION TO EXERCISE OPTION

     The  granting  of an option shall impose no obligation upon the optionee or
a transferee of the option to exercise such option.

     6. FINANCIAL ASSISTANCE

     Except  as  may  be prohibited by law, the Company is vested with authority
under  this  Plan to assist any employee to whom an option is granted or to whom
Shares are sold pursuant to a


                                      A-8


restricted  stock  purchase  agreement  hereunder  (including  any  director  or
officer  of  the  Company or any of its subsidiaries who is also an employee) in
the  payment  of  the purchase price payable on exercise of that option or under
that  restricted  stock  purchase  agreement,  by  lending  the  amount  of such
purchase  price  (including accepting a promissory note executed by the employee
as  consideration  for the sale of the Shares at the time the Shares are issued)
to  such  employee  on  such  terms  and at such rates of interest and upon such
security  (or  unsecured) as shall have been authorized by or under authority of
the Board or the Committee.

     7. FINANCIAL REPORTS.

     The  Company  shall deliver to each grantee of an option a balance sheet of
the  Company  as  at  the end of its most recently completed fiscal year, and an
income  statement  of  the  Company  as  of  the  end  of such fiscal year. Such
financial  statements  shall  be  delivered  no  less  frequently than annually;
provided,  that  such financial statements need not be delivered to any employee
whose duties as an employee assure them access to such financial information.
