Item 1. Description of Business

Overview

     BioTime,  Inc. (the "Company" or "BioTime") is a development  stage company
engaged in the research and development of synthetic  solutions that can be used
as blood plasma volume expanders, blood replacement solutions during hypothermic
(low  temperature)  surgery,  and organ  preservation  solutions.  Plasma volume
expanders  are used to treat  blood loss in surgical  or trauma  patients  until
blood loss  becomes so severe  that a  transfusion  of packed red blood cells or
other blood  products is  required.  The Company is also  developing a specially
formulated  hypothermic  blood  substitute  solution  that  would have a similar
function  and  would be used for the  replacement  of very  large  volumes  of a
patient's blood during cardiac  surgery,  neurosurgery  and other surgeries that
involve lowering the patient's body temperature to hypothermic levels.

     The Company's  first product,  Hextend(R),  is a  physiologically  balanced
blood plasma volume expander, for the treatment of hypovolemia. Hypovolemia is a
condition  often  associated  with blood  loss  during  surgery or from  injury.
Hextend maintains circulatory system fluid volume and oncotic pressure and keeps
vital  organs  perfused  during  surgery.  Hextend,  approved  for use in  major
surgery,  is the only blood plasma volume  expander  that  contains  hetastarch,
buffer,  multiple electrolytes and glucose.  Hextend is designed to compete with
and to replace products such as albumin and other colloid solutions,  as well as
crystalloid  solutions,  that have been used to maintain  fluid volume and blood
pressure  during surgery.  Hextend is also  completely  sterile to avoid risk of
infection. Health insurance reimbursements and HMO coverage now include the cost
of Hextend used in surgical procedures.

     Hextend is being sold in the United States by Abbott  Laboratories under an
exclusive license from the Company. Abbott also has the right to sell Hextend in
Canada, where an application for marketing approval is pending.  Abbott also has
a right to obtain licenses to manufacture and sell other BioTime  products.  See
"Licensing"   for  more   information   about  the  license  granted  to  Abbott
Laboratories.

     As part of the marketing  program,  a number of studies have been conducted
that show the advantages of receiving  Hextend and other BioTime products during
surgery.  For  example,  the  results  of a  clinical  trial by NJ  Wilkes et al
performed in England and entitled "The effects of balanced  versus  saline-based
hetastarch and  crystalloid  solutions on acid-base and  electrolyte  status and
gastric  mucosal  perfusion in elderly  surgical  patients" was published in the
October 2001 edition of Anesthesia  and Analgesia,  and  underscores a number of
Hextend  benefits  including  maintenance  of normal  acid-base  balance,  blood
calcium and chloride  levels and perfusion of portions of the  gastro-intestinal
tract.  As future  studies  such as these are  completed,  the  results  will be
presented at medical conferences and articles will be written for publication in
medical journals. The Company is also aware of independent studies using Hextend
that are being conducted which may be published in medical journals or reported

                                        2


at medical conferences.  The outcome of future medical studies and timing of the
publication  or  presentation  of the  results  could  have an effect on Hextend
sales.

     Hextend has been approved, or being considered for approval, by hundreds of
hospital formulary  committees.  Inclusion on hospital  formularies is important
because it enables  physicians  to obtain  Hextend  without  the need to special
order it. Obtaining  formulary approval generally takes several months and often
requires diligent efforts.

     The Company is also developing two other blood volume replacement products,
PentaLyte,(R)  and HetaCool,TM  that, like  Hextend,(R)  have been formulated to
maintain the patient's  tissue and organ  function by  sustaining  the patient's
fluid volume and physiological balance. Various colloid and crystalloid products
are being  marketed by other  companies  for use in  maintaining  patient  fluid
volume in surgery and trauma care, but those solutions do not contain the unique
comprehensive  combination of  electrolytes,  glucose,  lactate and hydroxyethyl
starch found in Hextend,  PentaLyte, and HetaCool. The Company's products do not
contain albumin.  Albumin produced from human plasma is also currently used as a
plasma expander, but it is expensive and subject to supply shortages.

     Based upon the results of its clinical studies and laboratory research, the
Company has determined that in many emergency care and surgical  applications it
is not necessary for a plasma volume expander to include special oxygen carrying
molecules  to replace red blood  cells.  Therefore,  the  Company is  developing
formulations  that do not use  costly  and  potentially  toxic  oxygen  carrying
molecules such as synthetic  hemoglobin and  perfluorocarbons.  However,  recent
laboratory  findings  by  Company  scientists  suggest  that  Hextend  can allow
hemoglobin-based oxygen carrier solutions to be used. more effectively.

     In order  to  commence  clinical  trials  for  regulatory  approval  of new
products, such as PentaLyte and HetaCool, or new therapeutic uses of Hextend, it
will  be  necessary  for  the  Company  to  prepare  and  file  with  the FDA an
Investigational  New Drug  Application  ("IND")  or an  amendment  to expand the
present IND for  additional  Hextend  studies.  Filings with foreign  regulatory
agencies will be required to commence clinical trials overseas.

     BioTime has  completed a Phase I clinical  trial of  PentaLyte  involving a
small number of subjects  and has  submitted  its  findings to the FDA.  BioTime
plans to test PentaLyte for the treatment of  hypovolemia in surgery.  PentaLyte
contains a lower molecular weight hydroxyethyl starch than Hextend,  and is more
quickly  metabolized.  PentaLyte is designed for use when short  lasting  volume
expansion is desirable.

     BioTime is also continuing to develop solutions for low temperature surgery
and trauma care. A number of  physicians  have  reported  using Hextend to treat
hypovolemia under mild hypothermic conditions during cardiac surgery. Additional
cardiac surgeries have been performed at deeper hypothermic temperatures. In one
case,  Hextend was used to treat  hypovolemia  in a cancer  patient  operated on
under  deep  hypothermic  conditions  in which the heart  was  arrested.  Once a
sufficient  amount of data from  successful  low  temperature  surgery  has been
compiled,  the Company plans to seek  permission to conduct trials using Hextend
as a complete  replacement  for blood under  near-freezing  conditions.  BioTime
currently plans to market Hextend for complete blood volume  replacement at very
low  temperatures  under  the  registered  trade  mark  "HetaCool(R)"  after FDA
approval is obtained.

                                        3


     The cost of preparing  regulatory filings and conducting clinical trials is
not presently  determinable,  but could be substantial.  It may be necessary for
the Company to obtain  additional funds in order to complete any clinical trials
that it may conduct for its new products or for new uses of Hextend.

     In addition to developing  clinical  trial  programs,  the Company plans to
continue to provide  funding  for its  laboratory  testing  programs at selected
universities,  medical  schools  and  hospitals  for the  purpose of  developing
additional uses of Hextend, PentaLyte, HetaCool, and other new products, but the
amount of research that will be conducted at those institutions will depend upon
the Company's financial status.

     The Company was  incorporated  under the laws of the State of California on
November  30,  1990.  The  Company's  principal  office is located at 935 Pardee
Street, Berkeley, California 94710. Its telephone number at such office is (510)
845-9535.

Products for Surgery, Plasma Volume Replacement and Emergency Care

The Market for Plasma Volume Expanders

     The Company is developing Hextend, PentaLyte,  HetaCool and other synthetic
plasma  expander  solutions to treat acute blood loss that occurs as a result of
trauma injuries and during many kinds of surgery.  These products are synthetic,
can be sterilized, and can be manufactured in large volumes. Hextend, PentaLyte,
and HetaCool contain constituents that may maintain  physiological  balance when
used to replace lost blood volume.

     Hextend is also  currently  being used to treat  hypovolemia  subsequent to
trauma  or sepsis by  emergency  room  physicians.  After  appropriate  clinical
testing and  regulatory  approval,  it may be used by  paramedics to treat acute
blood loss in trauma victims being transported to the hospital. Hextend has also
been  purchased  by the United  States  armed forces and may be used in cases of
battlefield trauma.

     Approximately  10,000,000  surgeries  take place in the United  States each
year, and blood  transfusions are required in  approximately  3,000,000 of those
cases.  Transfusions are also required to treat patients  suffering severe blood
loss due to traumatic injury. Many more surgical and trauma cases do not require
blood  transfusions  but do  involve  significant  bleeding  that can  place the
patient  at risk of  suffering  from  shock  caused by the loss of fluid  volume
(hypovolemia)  and  physiological  balance.  Whole  blood and  packed  red cells
generally cannot be administered to a patient until the patient's blood has been
typed and  sufficient  units of  compatible  blood or red cells can be  located.
Periodic  shortages of supply of donated human blood are not uncommon,  and rare
blood types are often difficult to locate.  The use of human blood products also
poses the risk of exposing the patient to blood borne  diseases such as AIDS and
hepatitis.

     Due to the  risks  and cost of using  human  blood  products,  even  when a
sufficient supply of compatible blood is available, physicians treating patients
suffering  blood loss are  generally  not permitted to transfuse red blood cells
until the patient's  level of red blood cells has fallen to a level known as the
"transfusion trigger." During the course of surgery, while blood volume is being
lost, the patient is infused with plasma volume  expanders to maintain  adequate
blood circulation. During the surgical

                                        4


procedure, red blood cells are not generally replaced until the patient has lost
approximately 45% to 50% of their red blood cells, thus reaching the transfusion
trigger at which point the transfusion of red blood cells may be required. After
the transfusion of red blood cells, the patient may continue to experience blood
volume loss, which will be replaced with plasma volume expanders.  Even in those
patients  who do not  require a  transfusion,  physicians  routinely  administer
plasma  volume  expanders  to  maintain  sufficient  fluid  volume to permit the
available red blood cells to circulate  throughout  the body and to maintain the
patient's physiological balance.

     Several units of fluid replacement  products are often administered  during
surgery.  The number of units will vary  depending upon the amount of blood loss
and the kind of plasma volume expander  administered.  Crystalloid products must
be used in  larger  volumes  than  colloid  products  such as  Hextend.  Albumin
produced from human plasma can be used for this purpose, but it is expensive and
subject  to  supply  shortages.  Additionally,  an  FDA  warning  has  cautioned
physicians about the risk of administering albumin to seriously ill patients.

The Market for Products for Hypothermic Surgery

     During  1997,  more than  500,000  coronary  bypass  and other  open  heart
surgeries were  performed in the United States  annually.  Approximately  18,000
aneurysm  surgeries  and  4,000  arterio-venous   malformation   surgeries  were
performed in the United States during 1989. Current estimates indicate that more
than 1,000,000  people over age 55 have  pathological  changes  associated  with
aortic  arch  aneurysms.   Open  heart  procedures  often  require  the  use  of
cardio-pulmonary  bypass  equipment to do the work of the heart and lungs during
the surgery. During open heart surgery and surgical procedures for the treatment
of certain  cardiovascular  conditions such as large  aneurysms,  cardiovascular
abnormalities and damaged blood vessels in the brain,  surgeons must temporarily
interrupt the flow of blood through the body.  Interruption of blood flow can be
maintained  only for short periods of time at normal body  temperatures  because
many  critical  organs,  particularly  the  brain,  are  quickly  damaged by the
resultant loss of oxygen. As a result, certain surgical procedures are performed
at low temperatures  because lower body temperature helps to minimize the chance
of damage to the  patient's  organs by reducing the  patient's  metabolic  rate,
thereby  decreasing the patient's  needs during surgery for oxygen and nutrients
which normally flow through the blood.

     Current  technology  limits  the  degree  to  which  surgeons  can  lower a
patient's  temperature and the amount of time the patient can be maintained at a
low body  temperature  because  blood,  even when diluted,  cannot be circulated
through  the body at  near-freezing  temperatures.  As a result,  surgeons  face
severe time constraints in performing surgical  procedures  requiring blood flow
interruption,  and those  time  limitations  prevent  surgeons  from  correcting
certain cardiovascular abnormalities.

     Hypothermic  techniques  may also have an important use in treating  trauma
patients that have  experienced  severe blood loss.  BioTime is sponsoring a new
project at the State  University of New York Health  Sciences Center in Brooklyn
to study  hypothermia and complete blood volume  replacement with HetaCool in an
animal model of civilian trauma.

Hextend, PentaLyte and HetaCool

     The  Company's  first three blood  volume  replacement  products,  Hextend,
PentaLyte,  and HetaCool have been  formulated to maintain the patient's  tissue
and organ  function by sustaining the patient's  fluid

                                        5


volume and physiological balance. Hextend, PentaLyte, and HetaCool, are composed
of a hydroxyethyl starch,  electrolytes,  sugar and a buffer in an aqueous base.
Hextend  and  HetaCool  use  a  high  molecular   weight   hydroxyethyl   starch
(hetastarch) whereas PentaLyte uses a lower molecular weight hydroxyethyl starch
(pentastarch).  The  hetastarch  is  retained  in  the  blood  longer  than  the
pentastarch,  which may make  Hextend and HetaCool the products of choice when a
larger  volume  of  plasma  expander  or  blood  replacement  solution  for  low
temperature  surgery is needed or where the patient's ability to restore his own
blood proteins after surgery is compromised.  PentaLyte, with pentastarch, would
be eliminated  from the blood faster than Hextend and HetaCool and might be used
when less  plasma  expander  is needed or where the  patient is more  capable of
quickly restoring lost blood proteins.  The Company has also tested HexaLyte,  a
new plasma volume  expander that  contains a low molecular  weight  hydroxyethyl
starch and that would be eliminated  from the body more rapidly than Hextend and
HetaCool, but not as rapidly as PentaLyte.  BioTime believes that by testing and
bringing  these  products to the market,  it can  increase  its market  share by
providing the medical community with solutions to match patients' needs.

     Certain  clinical  test  results  indicate  that  Hextend is  effective  at
maintaining blood calcium levels when used to replace lost blood volume. Calcium
can be a significant  factor in regulating blood clotting and cardiac  function.
Clinical  studies have also shown that Hextend  maintains  acid-base better than
saline-based  surgical  fluids.  The Company expects that PentaLyte will also be
able  to  maintain  blood  calcium  levels  and  acid-base  balance  based  upon
laboratory  studies and the fact that the formulation of PentaLyte is similar to
that of Hextend.

     BioTime has not attempted to synthesize potentially toxic and costly oxygen
carrying  molecules  such as  hemoglobin  because  the loss of fluid  volume and
physiological  balance may contribute as much to shock as the loss of the oxygen
carrying  component  of the blood.  Surgical and trauma  patients are  routinely
given  supplemental  oxygen  and retain a  substantial  portion of their own red
blood cells.  Whole blood or packed red blood cells are generally not transfused
during surgery or in trauma care until several units of plasma volume  expanders
have  been  administered  and  the  patient's   hematocrit  has  fallen  to  the
transfusion  trigger.  Therefore,  the lack of oxygen carrying  molecules in the
Company's solutions should not pose a significant contraindication to use.

     However, BioTime scientists have conducted laboratory animal experiments in
which they have shown that Hextend can be successfully  used in conjunction with
a hemoglobin-based  oxygen carrier solution approved for veterinary  purposes to
completely replace the animal's  circulating blood volume without any subsequent
transfusion and without the use of supplemental oxygen. By diluting these oxygen
carrier  solutions,   Hextend  may  reduce  the  potential  toxicity  and  costs
associated  with the use of those  products.  Once such  solutions have received
regulatory approval and become commercially available, this sort of protocol may
prove  valuable  in markets  in parts of the  developing  world  where the blood
supply is  extremely  unsafe.  These  applications  may also be useful in combat
where logistics make blood use impracticable.

     Hextend is BioTime's  proprietary  hetastarch-based  synthetic blood plasma
volume  expander,  designed  especially  to treat  hypovolemia  in surgery where
patients  experience  significant  blood loss. An important  goal of the Hextend
development  program was to produce a product  that can be used in multi-  liter
volumes.  The safety related secondary  endpoints  targeted in the U.S. clinical
study included those involving  coagulation.  The Company  believes that the low
incidence of adverse events  related to blood  clotting in the Hextend  patients
demonstrates that Hextend may be safely used in amounts exceeding 1.5 liters. An
average of 1.6 liters of Hextend was used in the Phase III clinical trials, with
an average of two

                                        6


liters for patients who received  transfused  blood  products.  Since then, more
than a quarter  million  units  (500 ml.  bags)  have  been sold for  commercial
purposes,  and the use of  quantities  of 7 to 8 liters  per  patient  have been
reported.  There have been no serious adverse events directly related to the use
of Hextend even when used in these large volumes.

     Hextend  is  also  being  used  in  surgery  with  cardio-pulmonary  bypass
circuits. In order to perform heart surgery, the patient's heart must be stopped
and a mechanical  apparatus is used to oxygenate and  circulate  the blood.  The
cardio-pulmonary  bypass  apparatus  requires a blood  compatible  fluid such as
Hextend to commence and maintain the process of diverting  the  patient's  blood
from the heart  and lungs to the  mechanical  oxygenator  and pump.  In a recent
clinical trial,  cardiac surgery patients treated with Hextend,  maintained more
normal kidney function,  experienced less pain and nausea, showed no deep venous
thromboses, avoided dialysis, and had shorter delay times to first meal compared
to those treated with other fluids.

     PentaLyte  is  BioTime's  proprietary  pentastarch-based  synthetic  plasma
expander,  designed  especially for use when a faster  elimination of the starch
component  is desired  and  acceptable.  Although  Hextend  can be used in these
cases,  some  physicians  appear to prefer a solution which could be metabolized
faster and excreted earlier when the longer term protection  provided by Hextend
is  not  required.  PentaLyte  combines  the  physiologically  balanced  Hextend
formulation  with  pentastarch  that has a lower molecular  weight and degree of
substitution  than the hetastarch used in Hextend.  Plasma expanders  containing
pentastarch  are currently  widely used around the world.  BioTime has completed
its Phase I clinical  study and is planning  more  advanced  PentaLyte  clinical
trials.  BioTime's  present plan is to seek approval of PentaLyte for use in the
treatment of hypovolemia.

     Abbott  has  certain  rights  of  first  refusal  to  obtain a  license  to
manufacture and market PentaLyte in the United States and Canada.

     HetaCool is a modified  formulation  of Hextend.  HetaCool is  specifically
designed for use at low  temperatures.  Surgeons are already  using a variety of
other solutions to carry out certain limited  procedures  involving shorter term
(up to nearly  one hour)  arrest of brain  and heart  function  at  temperatures
between 15o and 25o C. However, BioTime is not aware of any fluid currently used
in medical practice or any medically-approved protocol allowing operations which
can completely replace all of a patient's blood at temperatures close to the ice
point.  The  Company  believes  that  very low  temperature  bloodless  surgical
techniques could be developed for open heart and minimally invasive closed chest
cardiovascular surgeries,  removal of tumors from and the repair of aneurysms in
the  brain,  heart,  and other  areas,  as well as in the  treatment  of trauma,
toxicity and cancer.

     The Company is in the process of  preparing an amendment to its Hextend IND
application to conduct  clinical  trials using HetaCool as a solution to replace
all of a patient's circulating blood volume during profound hypothermic (carried
out  at  near-freezing   temperatures)  surgical  procedures.  The  experimental
protocol for the planned  blood  replacement  clinical  trial is being tested on
animal subjects. HetaCool would be introduced into the patient's body during the
cooling  process.  Once the patient's  body  temperature is nearly ice cold, and
heart and brain function are temporarily arrested, the surgeon would perform the
operation. During the surgery, HetaCool may be circulated throughout the body in
place of blood,  or the  circulation  may be arrested for a period of time if an
interruption of fluid  circulation is required.  Upon completion of the surgery,
the patient would be slowly warmed and blood would be transfused.

     Cardiac  surgeons are working to develop  innovative  procedures  to repair
damaged  coronary  arteries  and heart  valves.  If  optically  guided  surgical
instruments  can be  inserted  into the heart  through  blood  vessels  or small
incisions,  there may be no need to open the  patient's  chest  cavity.  BioTime
believes that HetaCool may be useful in these  minimally  invasive  closed chest
cardiac  procedures  because the solution is transparent  and if it were used to
completely  replace blood at low  temperatures  it would permit  surgeons to use
their  optically  guided  instruments  inside the heart or blood vessels without
having their view obstructed by blood.  The use of BioTime's  solutions may also
allow better control over stopping and starting the heart,  as well as extending
the time period of such surgeries.

     HetaCool has been used to completely  replace the blood volume of hamsters,
dogs,  pigs, and baboons at  temperatures  approaching  freezing.  Many of these
animal subjects  survived long term after  hypothermic  blood  substitution with
HetaCool. In these laboratory tests, the animals' blood was replaced by HetaCool
and  they  were  chilled  for  one to  more  than  four  hours  with  deep  body
temperatures between 1oC and 10oC.

     BioTime has recently  launched a research  program using HetaCool in animal
models of trauma at the State  University of New York Health  Science  Center in
Brooklyn.  Preliminary  laboratory  results  there have  already  supported  the
feasibility of using HetaCool to treat subjects following severe hemorrhage. The
use of HetaCool  at  near-freezing  temperatures  also will be studied in animal
models of  cardiovascular  surgery at the Texas Heart Institute in Houston.  The
project  has  been  approved  by the  appropriate  internal  committees,  and is
awaiting the beginning of experimentation.

     BioTime is  developing  a new  formulation  that has allowed the revival of
hamsters after as long as 6.5 hours of  hypothermic  blood  substitution  during
which time the animals' heartbeat and circulation were stopped.

     Abbott  has  certain  rights  of  first  refusal  to  obtain a  license  to
manufacture and market HetaCool in the United States and Canada.

Organ Transplant Products

The Market for Organ Preservation Solutions

     Organ  transplant  surgery  is a growing  field.  Each  year in the  United
States, approximately 5,000 donors donate organs, and approximately 5,000 people
donate skin, bone and other tissues.  As more surgeons have gained the necessary
expertise  and surgical  methods  have been  refined,  the number of  transplant
procedures has increased, as has the percentage of successful transplants. Organ
transplant  surgeons and their  patients  face two major  obstacles,  namely the
shortage of available organs from donors,  and the limited amount of time that a
transplantable  organ can be kept viable  between the time it is harvested  from
the donor and the time it is transplanted into the recipient.

     The scarcity of  transplantable  organs makes them too precious to lose and
increases the  importance  of effective  preservation  technology  and products.
Current organ removal and preservation  technology  generally  requires multiple
preservation  solutions to remove and preserve  effectively  different groups of
organs.  The  removal  of one organ can impair the  viability  of other  organs.
Available  technology  does not permit  surgeons  to keep the  remaining  organs
viable within the donor's body for a  significant  time after the first organ is
removed.  Currently,  an organ  available for  transplant is flushed with an ice
cold

                                        8


solution  during the removal  process to  deactivate  the organ and preserve its
tissues,  and then the organ is  transported  on ice to the donee.  The ice cold
solutions  currently used,  together with  transportation on ice, keep the organ
healthy for only a short  period of time.  For  example,  the  storage  time for
hearts is limited  to  approximately  six hours.  Because of the short time span
available for removal and transplant of an organ, potential organ donees may not
receive the needed organs.

     BioTime is seeking to address this problem by  developing a more  effective
organ   preservation   solution  that  will  permit   surgeons  to  harvest  all
transplantable  organs from a single donor. The Company believes that preserving
the viability of all transplantable  organs and tissues  simultaneously,  at low
temperatures,  would  extend by several  hours the time span in which the organs
can be preserved prior to transplant.

     Using  HetaCool  for  Multi-Organ  Preservation.  The Company is seeking to
develop HetaCool for use as a single solution that can  simultaneously  preserve
all of a single donor's  organs.  When used as an organ  preservation  solution,
HetaCool  would be  perfused  into the  donor's  body while the body is chilled,
thereby eliminating an undesirable condition called "warm ischemia," caused when
an organ is warm while its blood supply is  interrupted.  The use of HetaCool in
conjunction  with the  chilling of the body should help to slow down the process
of organ  deterioration  by a number of hours so that a surgeon  can  remove all
organs for donation and  transplant.  The Company's  current  estimates are that
each such preservation procedure could require as much as 50 liters of HetaCool.

     The Company believes that the ability to replace an animal's blood with the
Company's   HetaCool   solution,   to  maintain  the  animal  at  near  freezing
temperatures  for several hours, and then revive the animal,  would  demonstrate
that the solution could be used for multi-organ preservation. Company scientists
have revived animals after more than six hours of cold  blood-substitution,  and
have observed heart function in animals  maintained  cold and  blood-substituted
for  more  than  eight  hours.  An  objective  of  the  Company's  research  and
development  program is to extend the time span in which animal  subjects can be
maintained  in a cold,  blood-substituted  state  before  revival  or removal of
organs  for  transplant  purposes.  Organ  transplant  procedures  using  animal
subjects  could then be  conducted  to test the  effectiveness  of Hextend as an
organ preservative.

     A successful  transplant  of a lung cooled inside the donor's body prior to
transplant  has recently been  reported in Sweden.  The patient who received the
lung is  reported to be doing well  several  months  later.  The success of that
transplant,  which did not involve the use of a BioTime  product,  involved  the
preservation  and transplant of a single organ,  but indicates that  hypothermic
techniques  can be used to  preserve  organs in the donor  prior to removal  for
transplant.

Long-term Tissue and Organ Banking

     The   development  of  marketable   products  and   technologies   for  the
preservation  of tissues and vital  organs for weeks and months is a  long-range
goal of the Company's  research and  development  plan. To permit such long-term
organ  banking the Company is attempting  to develop  products and  technologies
that can  protect  tissues  and organs  from the damage  that  occurs when human
tissues are subjected to subfreezing temperatures.

     HetaFreeze  is one of a family  of  BioTime's  freeze-protective  solutions
which may ultimately allow the extension of time during which organs and tissues
can be stored for future transplant or surgical

                                        9


grafting. In laboratory  experiments,  BioTime's  proprietary  freeze-protective
compounds  have already  been used to preserve  skin when used as a whole animal
perfusate.  Silver  dollar size full  thickness  shaved skin  samples  have been
removed after  saturation  with HetaFreeze  solution,  frozen at liquid nitrogen
temperatures  and stored for periods ranging from days to weeks. The grafts were
then  warmed  and sewn  onto the  backs of host  animals.  Many of these  grafts
survived.

     In other laboratory experiments, BioTime scientists have shown that animals
can be revived to consciousness after partial freezing with their blood replaced
by HetaFreeze.  While this technology has not developed to an extent that allows
long term  survival  of the  laboratory  subjects,  and their  organs,  a better
understanding  of the  effects  of partial  freezing  could  allow for  extended
preservation times for vital organs, skin and blood vessels.

Other Potential Uses of BioTime Solutions

     Isolated  regional  perfusion of  anti-cancer  drugs has been used to treat
melanoma of the limbs, and inoperable  tumors of the liver. The Company believes
that  employing  such  a  procedure  while  the  patient  is  kept  in  ice-cold
blood-substitution  may  allow  high  doses  of  toxic  anti-cancer  drugs to be
directed at inoperable  tumors within vital organs,  which would  selectively be
warmed.  Keeping the rest of the patient in a cold, blood  substituted state may
reduce or eliminate the circulation of the toxic drugs to healthy tissues.

     BioTime considers such surgical techniques to be a longer range goal of its
research and development program for hypothermic  surgery products.  Use of this
complex  technology  in the practice of oncology  can occur only after  ice-cold
blood-substitution   has  advanced  to  an  appropriate   level  of  safety  and
effectiveness.

Research and Development Strategy

     From  inception  through  December  31,  2001,  the  Company  has  expensed
$21,630,518  on research  and  development.  The  greatest  portion of BioTime's
research  and  development  efforts  have been  devoted  to the  development  of
Hextend,  PentaLyte and HetaCool for conventional  surgery,  emergency care, low
temperature  surgery,  and  multi-organ  preservation.  A lesser  portion of the
Company's  research and  development  efforts  have been  devoted to  developing
solutions  and  protocols  for  storing   organs  and  tissues  at   subfreezing
temperatures.  In the future the Company may explore other  applications  of its
products and technologies,  including cancer chemotherapy. As the first products
achieve  market  entry,  more  effort will be expended to bring the next tier of
products to maturity.

     A major focus of the Company's  research and development effort has been on
products and technology to significantly  reduce or eliminate the need for blood
products  in  surgery  and trauma  care.  The  Company  has  recently  conducted
preliminary  studies using Hextend in a pressurized oxygen environment and found
that  Hextend can replace  nearly all, or in some cases all, of the  circulating
blood of rats. Some of the rats were able to live long term without a subsequent
transfusion, while others received their own blood back. In other cases, Hextend
was used in large volumes in association with a hemoglobin-based  oxygen carrier
solution  approved for veterinary  use. When used in this way, rats were able to
live long term after all their  circulating  blood was  replaced  at normal body
temperature breathing room air.

                                       10


     In still other  experiments,  rats were allowed to lose  approximately half
their  circulating  blood  volume,  and then  allowed to  develop  and remain in
respiratory arrest from 10-18 minutes.  They were then resuscitated with Hextend
and either  ventilated  with 100%  oxygen,  or in a  hyperbaric  oxygen  chamber
containing 100% oxygen at two  atmospheres  above normal  pressure.  Some of the
rats  recovered  and lived long term after as long as 15 minutes of  respiratory
arrest. The hyperbaric chamber appeared to have improved the outcome in a number
of cases.

     These studies indicate that Hextend can potentially be used in a variety of
protocols in which donor blood is difficult or impossible to use, such as on the
battlefield,  or in parts of the world where there is a shortage of disease-free
blood.

     Another major focus of the Company's  research and  development  effort has
been on products and  technology to extend the time animals can be kept cold and
blood-substituted,  and then revived without  physical  impairment.  An integral
part of that effort has been the  development  of techniques  and  procedures or
"protocols" for use of the Company's products.  A substantial amount of data has
been accumulated through animal tests, including the proper surgical techniques,
drugs and  anesthetics,  the temperatures and pressures at which blood and blood
replacement  solutions  should be removed,  restored  and  circulated,  solution
volume,  the temperature range, and times, for maintaining  circulatory  arrest,
and the rate at which the subject should be rewarmed.

     Experiments  intended to test the efficacy of the Company's low temperature
blood  replacement  solutions and protocols  for surgical  applications  involve
replacing the animal's blood with the Company's solution, maintaining the animal
in a cold  blood-substituted  state for a period of time, and then attempting to
revive  the  animal.   Experiments  for  multi-organ  preservation  involve  the
maintenance of the animal  subjects at cold  temperatures  for longer periods of
time  than  would  be  required  for many  surgical  applications,  followed  by
transplant  procedures  to test the  viability  of one or more of the  subject's
vital organs.

     The Company is conducting  experiments at hospitals,  medical schools,  and
university  research  facilities.  These  collaborative  research  programs  are
testing solutions and protocols developed in the Company's  laboratories and, in
some cases,  comparing the efficacy of the Company's  products with commercially
available FDA approved products  manufactured by other companies.  Collaborative
gerontological  research is being  conducting at the University of California at
Berkeley.  The Company  intends to continue to foster  relations  with  research
hospitals  and  medical  schools  for the  purpose of  conducting  collaborative
research  projects  because it believes that such  projects  will  introduce the
Company's  potential  products to members of the medical  profession and provide
the  Company  with  objective  product  evaluations  from  independent  research
physicians and surgeons.

     BioTime has also expanded its product  development efforts by initiating an
interventive  gerontology  program  focused on the  identification  of  specific
factors central to aging of the brain.  The program,  which is being  undertaken
with the cooperation of the University of California at Berkeley,  is focused on
the development of medical and  pharmacological  strategies to treat  senescence
related consequences.

Licensing

Abbott Laboratories

     On April 23, 1997, the Company and Abbott entered into a License  Agreement
under which the Company  granted to Abbott an exclusive  license to  manufacture
and sell Hextend in the United States and Canada for all therapeutic  uses other
than those involving hypothermic surgery where the patient's body temperature is
lower than 12(degree)C  ("Hypothermic Use"), or replacement of substantially all
of a patient's circulating blood volume ("Total Body Washout").  The Company has
retained all rights to  manufacture,  sell or license Hextend and other products
in all other countries.

     Under the Abbott License Agreement, Abbott has agreed to pay the Company up
to  $40,000,000  in license fees, of which  $2,500,000 has been paid to date for
the grant of the  license  and the  achievement  of  certain  milestones.  Up to
$37,500,000  of  additional  license fees will be payable  based upon annual net
sales of  Hextend,  at the rate of 10% of annual  net sales if annual  net sales
exceed  $30,000,000  or 5% if  annual  net sales are  between  $15,000,0000  and
$30,000,000.  Abbott's obligation to pay licensing fees on sales of Hextend will
expire on the earlier of January 1, 2007 or, on a country by country basis, when
all patents  protecting  Hextend in the  applicable  country expire or any third
party  obtains  certain  regulatory  approvals  to market a  generic  equivalent
product in that country.

     In addition to the license  fees,  Abbott will pay the Company a royalty on
total  annual  net  sales  of  Hextend.  The  royalty  rate  will  be 5% plus an
additional .22% for each $1,000,000 of annual net sales, up to a maximum royalty
rate of 36%. The royalty rate for each year will be applied on a total net sales
basis.  Abbott's  obligation to pay royalties on sales of Hextend will expire in
the  United  States  or  Canada  when  all  patents  protecting  Hextend  in the
applicable  country  expire  and any  third  party  obtains  certain  regulatory
approvals to market a generic equivalent product in that country.

     Abbott has agreed that the Company may convert Abbott's  exclusive  license
to a  non-exclusive  license or may  terminate  the license  outright if certain
minimum  sales and  royalty  payments  are not met.  In order to  terminate  the
license  outright,  the Company would pay a termination fee in an amount ranging
from the  milestone  payments  made by Abbott to an amount  equal to three times
prior year net sales, depending upon when termination occurs. Abbott's exclusive
license  also may  terminate,  without  the payment of  termination  fees by the
Company,  if Abbott fails to market  Hextend.  Abbott has agreed to  manufacture
Hextend for sale by the Company in the event that Abbott's  exclusive license is
terminated in either case.

     Abbott has certain rights to acquire additional licenses to manufacture and
sell the  Company's  other  plasma  expander  products in the United  States and
Canada.  If Abbott  exercises  these  rights to  acquire a license  to sell such
products  for uses other than  Hypothermic  Surgery  or Total Body  Washout,  in
addition  to paying  royalties,  Abbott will be  obligated  to pay a license fee
based upon the Company's  direct and indirect  research,  development  and other
costs  allocable to the new product.  If Abbott  desires to acquire a license to
sell any of the Company's products for use in Hypothermic  Surgery or Total Body
Washout,  the license  fees and other  terms of the  license  will be subject to
negotiation  between the parties.  For the purpose of determining the applicable
royalty  rates,  net sales of any such new  products  licensed by Abbott will be
aggregated  with sales of  Hextend.  If Abbott  does not  exercise  its right to
acquire a new product license,  the Company may manufacture and sell the product
itself or may license others to do so.

                                       12


     In order to  preserve  its  rights  to  obtain  an  exclusive  license  for
PentaLyte under its License  Agreement,  Abbott notified the Company that Abbott
will supply  BioTime with batches of PentaLyte,  characterization  and stability
studies,  and other  regulatory  support  needed for  BioTime to file an IND and
conduct clinical studies.

     The foregoing description of the Abbott License Agreement is a summary only
and is  qualified  in all respects by reference to the full text of that License
Agreement.

Other Licensing Efforts

     The Company is discussing  prospective  licensing  arrangements  with other
pharmaceutical  companies  that have  expressed  their interest in marketing the
Company's  products abroad.  In licensing  arrangements  that include  marketing
rights, the participating  pharmaceutical  company would be entitled to retain a
large  portion of the revenues from sales to end users and would pay the Company
a  royalty  on  net  sales.  There  is no  assurance  that  any  such  licensing
arrangements can be made.

Manufacturing

Manufacturing Arrangements

     Abbott  manufactures  Hextend  for the  North  American  market,  and  NPBI
International,  BV, a Netherlands  company  ("NPBI"),  has manufactured  lots of
Hextend for the Company's use in seeking regulatory  approval in Europe.  Abbott
and NPBI have the facilities to manufacture  Hextend and other BioTime  products
in  commercial  quantities.  If  Abbott  chooses  not to  obtain  a  license  to
manufacture  and  market  another  BioTime  product,  and if  NPBI  declines  to
manufacture  BioTime products on a commercial basis,  other  manufacturers  will
have to be found that would be willing to  manufacture  products  for BioTime or
any licensee of BioTime products.

Facilities Required

     Any products that are used in clinical  trials for  regulatory  approval in
the  United  States  or  abroad,  or that  are  approved  by the FDA or  foreign
regulatory authorities for marketing, have to be manufactured according to "good
manufacturing practices" at a facility that has passed regulatory inspection. In
addition,  products that are approved for sale will have to be  manufactured  in
commercial   quantities,   and  with  sufficient   stability  to  withstand  the
distribution   process,  and  in  compliance  with  such  domestic  and  foreign
regulatory  requirements  as may  be  applicable.  The  active  ingredients  and
component  parts of the products must be either USP or  themselves  manufactured
according to "good manufacturing practices".

     The  Company  does not have  facilities  to  manufacture  its  products  in
commercial  quantities,  or under "good  manufacturing  practices."  Acquiring a
manufacturing  facility would involve significant  expenditure of time and money
for design and construction of the facility,  purchasing  equipment,  hiring and
training a production staff,  purchasing raw material and attaining an efficient
level  of  production.  Although  the  Company  has not  determined  the cost of
constructing  production facilities that meet FDA requirements,  it expects that
the  cost  would  be  substantial,  and that  the  Company  would  need to raise
additional  capital in the future for that purpose.  To avoid the  incurrence of
those  expenses  and delays,  the Company is relying on contract  and  licensing
arrangements with established pharmaceutical

                                       13


companies  for the  production of the  Company's  products,  but there can be no
assurance that satisfactory  arrangements will be made for any new products that
the Company may develop.

Raw Materials

     Although most  ingredients in the products  being  developed by the Company
are readily  obtainable from multiple  sources,  the Company knows of only a few
manufacturers of the  hydroxyethyl  starches that serve as the drug substance in
Hextend,  PentaLyte and HetaCool. Abbott presently has a source of supply of the
hydroxyethyl starch used in Hextend,  PentaLyte and HetaCool,  and has agreed to
maintain a supply  sufficient  to meet  market  demand for Hextend in the United
States  and  Canada.  The  Company  believes  that it will be able to  obtain  a
sufficient  supply of starch for its needs in the foreseeable  future,  although
the  Company  does not have  supply  agreements  in place.  If for any  reason a
sufficient supply of hydroxyethyl starch could not be obtained, the Company or a
licensee  would have to acquire a  manufacturing  facility and the technology to
produce the hydroxyethyl starch according to good manufacturing  practices.  The
Company would have to raise additional capital to participate in the development
and acquisition of the necessary production technology and facilities.

     If  arrangements  cannot be made for a source  of  supply  of  hydroxyethyl
starch,  the Company would have to reformulate  its solutions to use one or more
other  starches that are more readily  available.  In order to  reformulate  its
products,  the Company would have to perform new laboratory testing to determine
whether the alternative starches could be used in a safe and effective synthetic
plasma volume expander,  low temperature blood substitute or organ  preservation
solution. If needed, such testing would be costly to conduct and would delay the
Company's product development  program,  and there is no certainty that any such
testing would  demonstrate  that an alternative  ingredient,  even if chemically
similar to the one currently used, would be as safe or effective.

Marketing

     Hextend  is being  sold by Abbott in the  United  States.  When  regulatory
approval is obtained, Hextend will be sold by Abbott in Canada as well.

     Hextend  has been  approved  for use and added to hospital  formularies  in
hundreds of hospitals. Inclusion on hospital formularies is important because it
enables physicians to obtain Hextend without the need to special order it.

     Because  Hextend is a surgical  product,  sales efforts must be directed to
physicians and hospitals.  The Hextend  marketing  strategy is designed to reach
its target customer base through sales calls and an advertising campaign focused
on the use of a  plasma-like  substance  to replace  lost  blood  volume and the
ability of Hextend to support vital physiological processes.

     Hextend competes with other products used to treat or prevent  hypovolemia,
including albumin,  generic 6% hetastarch solutions,  and crystalloid solutions.
The  competing  products  have been commonly used in surgery and trauma care for
many years, and in order to sell Hextend, physicians must be convinced to change
their product loyalties.  Although albumin is expensive,  crystalloid  solutions
and generic 6% hetastarch solutions sell at low prices. In order to compete with
other products, particularly

                                       14


those that sell at lower prices, Hextend will have to be recognized as providing
medically significant advantages.

     As part of the marketing  program, a number of studies have been conducting
that show the advantages of receiving  Hextend and other BioTime products during
surgery.  As these studies are  completed,  the results are presented at medical
conferences  and  articles  written for  publication  in medical  journals.  The
Company  is also  aware of  independent  studies  using  Hextend  that are being
conducted by physicians  and hospitals who may publish their findings in medical
journals or report their findings at medical conferences.  The outcome of future
medical  studies and timing of the  publication or  presentation  of the results
could have an effect on Hextend sales.

Government Regulation

     The FDA and foreign  regulatory  authorities  will  regulate the  Company's
proposed products as drugs, biologicals, or medical devices, depending upon such
factors as the use to which the product will be put,  the  chemical  composition
and the  interaction  of the  product on the human body.  In the United  States,
products  that  are  intended  to be  introduced  into the  body,  such as blood
substitute  solutions for low temperature surgery and plasma expanders,  will be
regulated  as drugs  and  will be  reviewed  by the FDA  staff  responsible  for
evaluating biologicals.

     The Company's  domestic human drug products will be subject to rigorous FDA
review and approval procedures. After testing in animals, an Investigational New
Drug (IND)  application must be filed with the FDA to obtain  authorization  for
human  testing.  Extensive  clinical  testing,  which is generally done in three
phases,  must then be undertaken at a hospital or medical  center to demonstrate
optimal use, safety and efficacy of each product in humans.  Each clinical study
is conducted  under the auspices of an  independent  Institutional  Review Board
("IRB"). The IRB will consider,  among other things, ethical factors, the safety
of human subjects and the possible  liability of the  institution.  The time and
expense  required to perform this  clinical  testing can far exceed the time and
expense  of the  research  and  development  initially  required  to create  the
product.  No action can be taken to market any therapeutic product in the United
States until an appropriate  New Drug  Application  ("NDA") has been approved by
the FDA. Even after initial FDA approval has been obtained,  further studies may
be required to provide additional data on safety or to gain approval for the use
of a product as a treatment for clinical  indications other than those initially
targeted. In addition,  use of these products during testing and after marketing
could  reveal side effects  that could  delay,  impede or prevent FDA  marketing
approval,   resulting  in  a  FDA-ordered  product  recall,  or  in  FDA-imposed
limitations on permissible uses.

     The FDA regulates the  manufacturing  process of  pharmaceutical  products,
requiring  that  they  be  produced  in  compliance  with  "good   manufacturing
practices."  See   "Manufacturing."  The  FDA  also  regulates  the  content  of
advertisements used to market pharmaceutical products. Generally, claims made in
advertisements  concerning  the  safety  and  efficacy  of  a  product,  or  any
advantages  of a product  over an other  product,  must be supported by clinical
data filed as part of an NDA or an amendment to an NDA, and statements regarding
the use of a product  must be  consistent  with the FDA  approved  labeling  and
dosage information for that product.

     Sales of  pharmaceutical  products outside the United States are subject to
foreign regulatory  requirements that vary widely from country to country.  Even
if  FDA  approval  has  been  obtained,  approval  of a  product  by  comparable
regulatory authorities of foreign countries must be obtained prior

                                       15


to the  commencement  of  marketing  the  product in those  countries.  The time
required to obtain such approval may be longer or shorter than that required for
FDA approval.

Patents and Trade Secrets

     The  Company  currently  holds  17  issued  United  States  patents  having
composition and methods of use claims covering BioTime's proprietary  solutions,
including Hextend and PentaLyte. The most recent U.S. patents were issued during
2001. Thirty patents covering certain of the Company's  solutions have also been
issued in the countries of the European Union,  Australia,  Israel, Russia, Hong
Kong, South Africa, Japan, and South Korea.  Additional patent applications have
been filed in the United  States  and  numerous  other  countries  for  Hextend,
PentaLyte and other  solutions.  Certain  device  patents  describing  BioTime's
hyperbaric  chamber,  and proprietary  microcannula have also been issued in the
United  States and  overseas,  both of which - although only used in research so
far - have possible indications in clinical medicine.

     There is no assurance that any additional  patents will be issued,  or that
any patents now held or later  obtained by the Company will not be  successfully
challenged  by third  parties and declared  invalid or infringing of third party
claims.  Further,  the  enforcement of patent rights often  requires  litigation
against third party infringers, and such litigation can be costly to pursue.

     In addition to patents,  the Company will rely on trade  secrets,  know-how
and continuing  technological  advancement to maintain its competitive position.
The Company has entered into intellectual property, invention and non-disclosure
agreements  with its employees  and it is the  Company's  practice to enter into
confidentiality  agreements  with its  consultants.  There can be no  assurance,
however, that these measures will prevent the unauthorized  disclosure or use of
the Company's  trade  secrets and know-how or that others may not  independently
develop  similar  trade  secrets and know-how or obtain  access to the Company's
trade secrets, know-how or proprietary technology.

Competition

     The Company's  solutions will compete with products currently used to treat
or  prevent  hypovolemia,   including  albumin,  other  colloid  solutions,  and
crystalloid  solutions  presently  manufactured  by  established  pharmaceutical
companies,  and with human blood products. Some of these products, in particular
crystalloid solutions,  are commonly used in surgery and trauma care and sell at
low prices.  In order to compete with other  products,  particularly  those that
sell at lower  prices,  the  Company's  products  will have to be  recognized as
providing medically significant advantages. Like Hextend, the competing products
are being manufactured and marketed by established pharmaceutical companies that
have large  research  facilities,  technical  staffs and financial and marketing
resources.  B.Braun  presently  markets  Hespan,  an  artificial  plasma  volume
expander  containing  6%  hetastarch  in  saline  solution.  Abbott  and  Baxter
International  manufacture and sell a generic  equivalent of Hespan. As a result
of the introduction of generic plasma expanders intended to compete with Hespan,
competition in the plasma expander  market has intensified and wholesale  prices
have declined.  Abbott,  which markets Hextend for BioTime in the Untied States,
is also the leading seller of generic 6% hetastarch in saline solution.  Aventis
Behring,  LLC, Baxter  International,  and Alpha Therapeutics sell albumin,  and
Abbott, Baxter International and B.Braun sell crystalloid solutions

                                       16


     To  compete  with  new and  existing  plasma  expanders,  the  Company  has
developed  products  that  contain  constituents  that may prevent or reduce the
physiological imbalances, bleeding, fluid overload, edema, poor oxygenation, and
organ failure that can occur when  competing  products are used. To compete with
existing organ preservation solutions,  the Company has developed solutions that
can be used to preserve all organs simultaneously and for long periods of time.

     A number of other  companies  are  known to be  developing  hemoglobin  and
synthetic red blood cell substitutes and technologies.  BioTime's  products have
been  developed  for  use  either  before  red  blood  cells  are  needed  or in
conjunction  with the use of red blood cells. In contrast,  hemoglobin and other
red blood cell  substitute  products are designed to remedy ischemia and similar
conditions  that may result from the loss of oxygen  carrying  red blood  cells.
Those products would not necessarily  compete with the Company's products unless
the  oxygenating  molecules  were included in solutions that could replace fluid
volume and prevent or reduce the physiological  imbalances as effectively as the
Company's products.  Generally, red blood cell substitutes are more expensive to
produce and potentially more toxic than Hextend and PentaLyte.

     Competition  in the areas of business  targeted by the Company is likely to
intensify  further as new products and technologies  reach the market.  Superior
new products are likely to sell for higher  prices and  generate  higher  profit
margins once  acceptance by the medical  community is achieved.  Those companies
that are successful in introducing  new products and  technologies to the market
first may gain  significant  economic  advantages over their  competitors in the
establishment  of a customer base and track record for the  performance of their
products and  technologies.  Such companies will also benefit from revenues from
sales  which  could  be used  to  strengthen  their  research  and  development,
production,  and  marketing  resources.  All  companies  engaged in the  medical
products   industry  face  the  risk  of  obsolescence  of  their  products  and
technologies as more advanced or cost effective  products and  technologies  are
developed by their competitors.  As the industry matures, companies will compete
based upon the performance and cost effectiveness of their products.

Employees

     As of December 31, 2001,  the Company  employed nine persons on a full-time
basis and three persons on a part-time basis. Three full-time  employees and one
part-time employee hold Ph.D. Degrees in one or more fields of science.

Risk Factors

     Some of the factors that could materially  affect the Company's  operations
and  prospects  are  discussed  below.  There may be other  factors that are not
mentioned here or of which BioTime is not presently aware that could also affect
BioTime's operations.

Development Stage Company; Continuing Operating Losses

     BioTime  is in the  development  stage,  and,  is  principally  engaged  in
research and development  activities.  To date, the Company's operating revenues
have been generated primarily from licensing fees, including $2,500,000 received
from Abbott for the right to manufacture and market Hextend in the United States
and Canada.  Only one of the Company's  products is presently on the market, and
since the

                                       17


Company  received  FDA approval to market  Hextend it has  received  $204,409 of
royalties on sales. As a result of the developmental  nature of its business and
the limited sales of its product, since the Company's inception in November 1990
it has  incurred  $30,770,238  of  losses.  There can be no  assurance  that the
Company  will  generate  sufficient  revenues  from  licensing  its products and
technologies and from royalties on sales of its products to be profitable.

Uncertainty of Future Sales; Competition

     The Company's  ability to generate  substantial  operating  revenue depends
upon the ability of Abbott to successfully  market Hextend and any other BioTime
products  that they may license in the future.  There can be no  assurance  that
Hextend or any other  products that receive FDA or foreign  regulatory  approval
will be  successfully  marketed  or that the  Company  will  receive  sufficient
revenues from product sales to meet its operating expenses.

     Widespread  acceptance of the Company's  products and  technologies  by the
medical  profession  will take  time to  develop  because  many  physicians  and
hospitals  are  reluctant  to try a new  product  due to the high degree of risk
associated with the application of new technologies and products in the field of
human medicine.

     Hextend and  BioTime's  other plasma  expander  products  will compete with
products currently used to treat or prevent  hypovolemia,  including albumin and
other colloid solutions,  and crystalloid solutions.  Some of these products, in
particular crystalloid  solutions,  are commonly used in surgery and trauma care
and sell at low prices.  In order to compete with other  products,  particularly
those  that  sell at  lower  prices,  the  Company's  products  will  have to be
recognized as providing medically significant  advantages.  Such recognition may
come  from the  publication  of  medical  studies  in  medical  journals  or the
presentation of the results of such studies at medical  conferences.  While some
studies  of  Hextend  have  already  been  published  or  presented  at  medical
conferences,  it will take time to complete  further studies and for the results
of those studies to be published or presented.

     Products  that  compete  with  Hextend are being  manufactured  and sold by
established  pharmaceutical  companies  with  substantial  resources.  B.  Braun
presently  sells Hespan,  an artificial  plasma volume expander that contains 6%
hetastarch in saline solution.  Abbott and Baxter International  manufacture and
sell a generic  equivalent of Hespan. As a result of the introduction of generic
plasma  expanders  intended to compete  with Hespan,  competition  in the plasma
expander  market has  intensified  and wholesale  prices have declined.  Aventis
Behring, LLC, Baxter International, and Alpha Therapeutics sell albumin. Abbott,
Baxter  International and B. Braun sell crystalloids.  There also is a risk that
the  Company's  competitors  may succeed in developing  safer or more  effective
products that could render the Company's  products and technologies  obsolete or
noncompetitive.

BioTime Needs to Raise Additional Capital

     The Company  needs to raise capital to meet its  operating  expenses  until
such time as it is able to generate  sufficient  revenues  from product sales or
royalties.  In  August  2001,  BioTime  raised  $3,350,000  through  the sale of
debentures  to a group of  private  investors.  In March  of 2002,  the  Company
entered  into a Credit  Agreement  with  Alfred D.  Kingsley,  an  investor  and
consultant to the Company, under which the Company may borrow up to $300,000 for
working capital purposes. Amounts borrowed under

                                       18


the Credit  Agreement will bear interest at 10% per annum and will be due in one
year or when  BioTime  receives  at least  $600,000  through the sale of capital
stock,  loans from other lenders,  fees under  licensing  agreements  (excluding
royalty payments), or any combination of those sources. Mandatory prepayments of
principal will be due to the extent that the Company receives funds from any one
or more of those sources in excess of $300,000 but less than  $600,000,  and the
amount of any such  mandatory  prepayments  of principal will reduce the maximum
amount available under the Credit Agreement and will not be available for future
borrowings.  The Company will have the right to make  voluntary  prepayments  of
principal that would  otherwise not be due,  without penalty or premium but with
accrued  interest,  at any time,  and any amounts  voluntarily  prepaid  will be
available for future borrowings,  so long as the Company is not in default under
the Credit  Agreement,  and the outstanding  principal  balance loaned under the
Credit  Agreement does not exceed  $300,000.  Although BioTime believes that its
cash on hand and funds available  under the Credit  Agreement will be sufficient
to allow it to continue its operations on a limited scale for 12 months, it will
need  additional  funds to begin clinical trials of PentaLyte and to conduct its
other product development and research programs.  There can be no assurance that
the Company will be able to raise additional funds on favorable terms or at all,
or that such  funds,  if raised,  will be  sufficient  to permit the  Company to
continue  its  operations,  notwithstanding  the  progress of its  research  and
development  projects.  The  Company's  operating  expenses  will increase if it
succeeds in bringing  additional products out of the laboratory testing phase of
development and into clinical trials.  Additional financing will be required for
the continuation or expansion of the Company's research and product development,
additional  clinical  trials of new products,  and  production  and marketing of
Company products that receive FDA or foreign regulatory  approval.  Although the
Company will continue to seek licensing fees from  pharmaceutical  companies for
licenses to manufacture  and market new products such as PentaLyte and HetaCool,
additional  sales of  equity or debt  securities  will be  required  to meet the
Company's  short-term capital needs. Sales of additional equity securities could
result in the dilution of the interests of present shareholders.

BioTime Products Cannot Be Marketed Without FDA and Other Regulatory Approvals

     The  products  that  BioTime  develops  cannot  be sold  until  the FDA and
corresponding  foreign regulatory  authorities  approve the products for medical
use.  The  regulatory  process,   which  includes   preclinical,   clinical  and
post-clinical testing of each product to establish its safety and efficacy,  can
take several years to complete and require the  expenditure of substantial  time
and  funds.   Data  obtained  from  preclinical  and  clinical   activities  are
susceptible  to varying  interpretations  which  could  delay,  limit or prevent
regulatory approval.  In addition,  delays or rejections may be encountered as a
result of changes in FDA policy during the period of product development and FDA
regulatory review.  Similar delays may also be encountered in foreign countries.
There can be no assurance that, even after substantial  expenditures of time and
money,  regulatory  approval will be obtained for any new products  developed by
the Company. Moreover, even if regulatory approval of a product is granted, such
approval may entail  limitations on the indicated uses for which the product may
be marketed.  After regulatory approval is obtained,  the approved product,  the
manufacturer  and the  manufacturing  facilities are subject to continual review
and periodic  inspections,  and a later discovery of previously unknown problems
with a product,  manufacturer  or  facility  may result in  restrictions  on the
product or  manufacturer,  including  withdrawal of the product from the market.
Failure to comply with the applicable  regulatory  requirements can, among other
things, result in fines,  suspensions of regulatory approvals,  product recalls,
operating   restrictions  and  criminal   prosecution.   Additional   government
regulation may be established  which could prevent or delay regulatory  approval
of the Company's products.

                                       19


Uncertainty as to the Successful Development of Medical Products

     The Company's business involves the attempt to develop new medical products
and technologies.  Such experimentation is inherently costly, time consuming and
uncertain as to its results.  If the Company is  successful  in developing a new
technology  or  product,  refinement  of  the  new  technology  or  product  and
definition of the practical  applications  and  limitations of the technology or
product may take years and require the expenditure of large sums of money.  From
the date of the  Company's  inception  through  December 31,  2001,  the Company
expensed  $21,630,518 on research and  development,  and the Company  expects to
continue to incur substantial research and development expenses.


Absence of Manufacturing and Marketing Capabilities; Reliance Upon Licensing

     The Company  presently  does not have  adequate  facilities or resources to
manufacture  its products or the  hydroxyethyl  starches  used in its  products.
BioTime  has  granted  Abbott an  exclusive  license to  manufacture  and market
Hextend  in the  United  States  and  Canada,  and  BioTime  plans to enter into
additional  arrangements  with  pharmaceutical  companies for the production and
marketing  of  the  Company's  products  in  other  countries.  There  can be no
assurance   that  the  Company  will  be   successful  in  entering  into  those
arrangements.

Patents May Not Protect BioTime Products from Competition

     The Company has  obtained  patents in the United  States,  countries of the
European Union,  Australia,  Israel, Russia, Hong Kong, South Africa, Japan, and
South Korea, and has filed patent applications in certain foreign countries, for
certain  products,  including  Hextend and PentaLyte.  No assurance can be given
that any additional patents will be issued to the Company, or that the Company's
patents will provide meaningful  protection against the development of competing
products.  There also is no assurance  that  competitors  will not  successfully
challenge  the validity or  enforceability  of any patent issued to the Company.
The costs required to uphold the validity and prevent infringement of any patent
issued to the Company could be  substantial,  and the Company might not have the
resources available to defend its patent rights.

Prices and Sales of Products  May be Limited by Health  Insurance  Coverage  and
Government Regulation

     Success in selling  BioTime's  products may depend in part on the extent to
which health insurance  companies,  HMOs, and government  health  administration
authorities  such as Medicare and Medicaid will pay for the cost of the products
and related  treatment.  Health  insurance  reimbursements  and HMO coverage now
include the cost of Hextend used in surgical procedures.  However,  there can be
no assurance that such reimbursements will continue.  In some foreign countries,
pricing or  profitability  of health  care  products  is  subject to  government
control.  In the United  States,  there have been a number of federal  and state
proposals to implement similar government controls, and new proposals are likely
to be made in the future.

                                       20


Dependence Upon Key Personnel

     The Company depends to a considerable  degree on the continued  services of
its  executive  officers.  The  loss  of the  services  of any of the  executive
officers could have a material adverse effect on the Company.  In addition,  the
success of the  Company  will  depend,  among  other  factors,  upon  successful
recruitment   and  retention  of  additional   highly  skilled  and  experienced
management and technical personnel.

BioTime Does Not Pay Cash Dividends

     BioTime  does  not  pay  cash  dividends  on its  Common  Shares.  For  the
foreseeable  future  it is  anticipated  that any  earnings  generated  from the
Company's  business  will be used to finance  the growth of the Company and will
not be paid out as  dividends to BioTime  shareholders.  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.

The Price of BioTime Stock May Rise and Fall Rapidly

     BioTime Common Shares are traded on the American Stock Exchange. The market
price of the Common Shares,  like that of the common stock of many biotechnology
companies,  has been  highly  volatile.  The price of  BioTime  shares  may rise
rapidly in  response to certain  events,  such as the  commencement  of clinical
trials of an experimental  new drug, even though the outcome of those trials and
the likelihood of ultimate FDA approval remains uncertain.  Similarly, prices of
BioTime  shares  may  fall  rapidly  in  response  to  certain  events  such  as
unfavorable  results  of  clinical  trials or a delay or  failure  to obtain FDA
approval.  The failure of the Company's earnings to meet analysts'  expectations
could result in a significant rapid decline in the market price of the Company's
shares.  In  addition,  the  stock  market  has  experienced  and  continues  to
experience extreme price and volume  fluctuations which have affected the market
price of the equity  securities of many  biotechnology  companies and which have
often been unrelated to the operating performance of these companies. Such broad
market fluctuations,  as well as general economic and political conditions,  may
adversely affect the market price of BioTime Common Shares.

Item 2. Facilities.

     The  Company  occupies  its office and  laboratory  facility  in  Berkeley,
California  under a lease  that  will  expire  on March 31,  2004.  The  Company
presently occupies approximately 8,890 square feet of space and pays rent in the
amount of $11,024 per month.  The rent will increase  annually by the greater of
3% and the  increase in the local  consumer  price  index,  subject to a maximum
annual  increase of 7%. The Company  also pays all  charges  for  utilities  and
garbage collection.

     The  Company  has an option to extend the term of the lease for a period of
three years, and to terminate the lease early upon six months notice.

     The Company uses, on a fee per use basis,  facilities for surgical research
on animals at an unaffiliated  privately run research center located in Winters,
California.  Contracting  for the use of  research  facilities  has  enabled the
Company to initiate its research projects without the substantial  capital cost,
overhead

                                       21


costs and delay  associated  with the  acquisition  and  maintenance of a modern
animal surgical research facility.

Item 3. Legal Proceedings.

     The  Company  is not  presently  involved  in any  material  litigation  or
proceedings,  and to the Company's  knowledge no such  litigation or proceedings
are contemplated.

Item 4. Submission of Matters to a Vote of Security Holders.

     None.

Item 5. Market for Registrant's Common Equity and Related Stockholder Matters.

     The  Company's  Common  Shares  have been  trading  on the  American  Stock

Shares based upon information from the Registrar and Transfer Agent.

     The Company has paid no dividends on its Common  Shares since its inception
and does not plan to pay  dividends  on its  Common  Shares  in the  foreseeable
future.  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 in full the  indebtedness  on  certain  debentures  issued
during  August  2001.  See  "Management's  Discussion  and Analysis of Financial
Condition and Results of Operations-Liquidity and Capital Resources."

     During the three month  periods  ended  September 30, 2001 and December 31,
2001,   the  Company   issued  862  common  shares  and  1,087  common   shares,
respectively,  to  Milton  D.  Dresner  in lieu of a cash fee for  serving  as a
director.  The shares were issued without  registration under the Securities Act
of 1933,  as amended,  pursuant to the exemption  provided in Section 4(2).  See
"Directors' Meetings, Compensation and Committees of the Board."

Item 7. Management's  Discussion and Analysis of Financial Condition
        and Results of Operations.

Overview

     Since  its  inception  in  November  1990,  the  Company  has been  engaged
primarily in research and  development  activities  which have culminated in the
commercial  launch  of  Hextend,  its  lead  product,  and a  clinical  trial of
PentaLyte.  The Company's  operating revenues have been generated primarily from
licensing fees,  including  $2,500,000 received from Abbott Laboratories for the
right to manufacture and market Hextend(R) in the United States and Canada. As a
result of the developmental  nature of its business and the limited sales of its
product,  since  the  Company's  inception  in  November  1990  it has  incurred
$30,770,238 of losses. The Company's ability to generate  substantial  operating
revenue  depends upon its success in  developing  and marketing or licensing its
plasma volume  expanders and organ  preservation  solutions and  technology  for
medical use.

     Most of the Company's research and development efforts have been devoted to
the  Company's  first  three  blood  volume  replacement  products:  Hextend,(R)
PentaLyte,(R)  and  HetaCool.(TM)  By testing and bringing all three products to
the market,  BioTime can  increase  its market  share by  providing  the medical
community with solutions to match patients' needs. By developing  technology for
the  use  of  HetaCool  in low  temperature  surgery,  trauma  care,  and  organ
transplant surgery,  BioTime may also create new market segments for its product
line.

     The Company's first product,  Hextend, is a physiologically  balanced blood
plasma volume expander, for the treatment of hypovolemia.  Hextend is being sold
in the United States by Abbott  Laboratories under an exclusive license from the
Company.  Abbott  also  has the  right  to sell  Hextend  in  Canada,  where  an
application for marketing approval is pending. Abbott also has a right to obtain
licenses to manufacture and sell other BioTime products.

     Under its License  Agreement with the Company,  Abbott will report sales of
Hextend  and pay the Company the  royalties  and license  fees due on account of
such sales within 90 days after the end of each  calendar  quarter.  The Company
recognizes  such  revenues in the quarter in which the sales report is received,
rather than the quarter in which the sales took place,  as the Company  does not
have sufficient sales history to accurately  predict  quarterly  sales.  Hextend
sales are still in the ramp- up phase.

     Revenues for the year ended  December  31, 2001 include  royalties on sales
made by Abbott during the period beginning  October 1, 2000 and ending September
30, 2001.  Royalties on sales  recognized  as revenues made during that 12 month
period were  $151,917.  Royalties on sales during the three month period  ending
December  31, 2001 were  $57,235 but will not be  recognized  by the Company for
financial  accounting  purposes  until the first  quarter  of fiscal  year 2002.
Hextend sales are still in the ramp-up phase , as  illustrated  by the following
graph:

                                       25

                    Semi-Annual Hextend(R) Sales ($ millions)

                     Jul-Dec'99                       0.3
                     Jan-Jun'00                       0.5
                     Jul-Dec'00                       1.0
                     Jan-Jun'01                       1.2
                     Jul-Dec'01                       1.9


     The graph  illustrates  semi-annual sales of Hextend derived from quarterly
sales reports provided to BioTime by Abbott with royalty payments.  Royalties on
sales that  occurred  during the third quarter of 1999 through the third quarter
of 2000 are reflected in the Company's  financial  statements for the year ended
December 31, 2000.  Royalties on sales that occurred during the third quarter of
2000 through the third quarter of 2001 are reflected in the Company's  financial
statements  for the year  ended  December  31,  2001.  Royalties  on sales  that
occurred  during the fourth  quarter of 2001 will be reflected in the  Company's
financial statements for the first quarter of 2002.

     As shown above,  semi-annual  sales of Hextend have increased 760% from the
last half of 1999, when the product was first launched, through the last half of
2001.  Sales  during  the last  half of 2001 were  strong  despite  the  adverse
influences of the events of September 11, 2001, and sales of Hextend continue to
rise  progressively  from year to year.  BioTime attributes these gains in semi-
annual sales to escalating marketing efforts, an accelerating demand for Hextend
by physicians and hospitals due to its outstanding  performance in many hundreds
of operating  rooms around the country,  and recent clinical trial results which
highlight its many clinical benefits.  Based on preliminary  estimates,  current
monthly  sales of  Hextend  are nearly  half of the amount of monthly  sales the
Company needs to operate at the break-even  point at the present reduced rate of
Company  spending,  which  includes  substantial  salary  reductions and limited
research and development activities.

     As part of the marketing  program,  a number of studies have been conducted
that show the advantages of receiving  Hextend and other BioTime products during
surgery. For example, the

                                       26


results of a clinical trial by NJ Wilkes et al performed in England and entitled
"The  effects  of  balanced  versus  saline-based   hetastarch  and  crystalloid
solutions on acid-base and electrolyte  status and gastric mucosal  perfusion in
elderly  surgical  patients"  was  published  in the  October  2001  edition  of
Anesthesia and Analgesia, and underscores a number of Hextend benefits including
maintenance of normal acid-base  balance,  blood calcium and chloride levels and
perfusion of portions of the gastro-intestinal tract.  Furthermore,  the results
of a clinical  study of 200 cardiac  surgery  patients  at  Columbia  University
Medical  Center in New York were  presented  at the 2001  Annual  Meeting of the
Anesthesiology Society of America. In that study, patients receiving Hextend had
better outcomes than patients  receiving other surgical fluids (6% hetastarch in
normal saline, albumin in saline and lactated Ringer's),  based upon maintenance
of renal function,  avoidance of dialysis,  avoidance of deep venous thromboses,
lower level of pain, nausea and suffering,  shorter time to first meal, and less
clotting abnormalities.

     As  future  studies  such as  these  are  completed,  the  results  will be
presented at medical conferences and articles will be written for publication in
medical journals. The Company is also aware of independent studies using Hextend
that are being  conducted by  physicians  and  hospitals  who may publish  their
findings in medical  journals or report their  findings at medical  conferences.
The  outcome  of  future  medical  studies  and  timing  of the  publication  or
presentation of the results could have an effect on Hextend sales.

     Hextend  has become the  standard  plasma  volume  expander  at a number of
prominent teaching hospitals and leading medical centers.  BioTime feels that as
Hextend  use  proliferates  within  the  leading  US  hospitals,  other  smaller
hospitals will follow their lead and accelerate sales growth.

     Hextend is being  evaluated by a number of military  physicians as a plasma
volume expander in the treatment of hypovolemia in combat  casualties.  This was
the topic of a number of formal  presentations  and  discussions at Combat Fluid
Resuscitation  2001, a meeting held at the Uniformed Services  University of the
Health Sciences in Bethesda,  Maryland in June,  2001,  under their auspices and
that of the  Office  of Naval  Research  and the US Army  Medical  Research  and
Materiel  Command.  Additionally,  a meeting  was held at  Hahnemann  University
Medical  College of  Pennsylvania  in  Philadelphia  on October 8, 2001 at which
military  and  civilian  medical  and  scientific   personnel  discussed  making
recommendations  to the United States military on the use of intravenous  fluids
and medical  devices to treat  combat  casualties.  Hextend was among the fluids
considered during this meeting.

     The Company  has  completed a Phase I clinical  trial of  PentaLyte  and is
planning the next phase of its clinical  trials in which  PentaLyte will be used
to treat hypovolemia in surgery.

     The Company is also  continuing to develop  solutions  for low  temperature
surgery.  Once a  sufficient  amount of data  from  successful  low  temperature
surgery has been compiled,  the Company plans to seek  permission to use Hextend
as a complete  replacement  for blood under  near-freezing  conditions.  BioTime
currently plans to market Hextend for complete blood volume  replacement at very
low  temperatures  under the  registered  trade  mark  "HetaCool(TM)"  after FDA
approval is obtained.

     Abbott has an option to obtain a license to market  PentaLyte  and HetaCool
in the United States and Canada,  and BioTime would receive  additional  license
fees if those options are exercised,

                                       27


in addition to  royalties on  subsequent  sales of those  products.  BioTime and
certain  pharmaceutical   companies  are  discussing  potential   manufacturing,
distributing  and marketing  agreements for BioTime  products in the rest of the
world.

     In order  to  commence  clinical  trials  for  regulatory  approval  of new
products or new  therapeutic  uses of  products,  it will be  necessary  for the
Company to prepare and file with the FDA an Investigational New Drug Application
("IND")  or an  amendment  to expand a previous  filing.  Filings  with  foreign
regulatory  agencies will be required to commence clinical trials overseas.  The
Company  has filed an  application  to market  Hextend in Canada,  and its first
application for approval in a European Union member nation,  Sweden.  Regulatory
approvals  for other  countries  that are members of the  European  Union may be
obtained through a mutual recognition  process.  If approvals can be obtained in
the requisite  number of member nations,  then the Company would be permitted to
market Hextend in all 16 member nations.  BioTime is continuing to work with the
appropriate officials to achieve regulatory approval in Canada and Sweden.

     In addition to developing  clinical  trial  programs,  the Company plans to
continue to provide  funding  for its  laboratory  testing  programs at selected
universities,  medical  schools  and  hospitals  for the  purpose of  developing
additional uses of Hextend, PentaLyte, HetaCool, and other new products, but the
amount of research that will be conducted at those institutions will depend upon
the Company's  financial status.  Because the Company's research and development
expenses, clinical trial expenses, and production and marketing expenses will be
charged against earnings for financial  reporting  purposes,  management expects
that  there will be losses  from  operations  from time to time  during the near
future.

     Hextend(R) and PentaLyte(R) are registered trademarks,  and HetaCool(TM) is
a trademark, of BioTime.

Results of Operations

Year Ended December 31, 2001 and Year Ended December 31, 2000

     For the year ended  December 31, 2001, the Company  recognized  $151,917 of
royalty revenues.  Under its License Agreement with the Company,  Abbott reports
sales of Hextend  and pays the  Company the  royalties  and license  fees due on
account of such sales within 90 days after the end of each calendar quarter. The
Company  recognizes  such  revenues in the quarter in which the sales  report is
received,  rather than the quarter in which the sales took place, as the Company
does not have sufficient  sales history to accurately  predict  quarterly sales.
Royalties on sales made during the fourth quarter of 2001 will not be recognized
by the Company until the first quarter of fiscal year 2002.

     For the year ended December 31, 2001,  interest and other income  decreased
to $114,344 from $165,256 for the year ended  December 31, 2000. The decrease is
attributable to lower interest rates and cash balances for 2001, versus 2000.

                                       28


     Research and  development  expenses  decreased to  $1,685,168  for the year
ended  December 31, 2001,  down from  $3,362,841 for the year ended December 31,
2000. The decrease is attributable to a significant decrease in laboratory study
expenses and fees paid to  scientific  research  personnel as a result of a cost
reduction  program in which the Company  reduced its  research  and  development
activities. Research and development expenses include laboratory study expenses,
European clinical trial expenses, salaries, preparation of additional regulatory
applications  in the United  States and Europe,  manufacturing  of solution  for
trials,  and  consultants'  fees. It is expected  that research and  development
expenses will increase if the Company obtains sufficient capital to commence new
clinical studies of its products in the United States and Europe.

     General and  administrative  expenses  increased to $1,961,342 for the year
ended  December 31, 2001 from  $1,779,931  for the year ended December 31, 2000.
This increase is attributable to significant  increases in expenditures  for the
Company's Annual Report and Meeting,  fees required for continued stock exchange
listing,  overall insurance costs,  investor/public  relations costs,  legal and
accounting  fees,  and  costs  associated  with  continued  maintenance  of  the
Company's patent portfolio.

     The company's interest expense increased by $278,576 during 2001 because it
began to borrow money to meet its capital needs.

Year Ended December 31, 2000 and Year Ended December 31, 1999

     For the year ended  December 31, 2000,  the Company  recognized  $52,492 of
royalty  revenues.  During  Fiscal 1999 the  Company  recognized  $1,037,500  of
license fees that were received  from Abbott during prior years.  No license fee
revenue was received in Fiscal 2000.

     For the year ended December 31, 2000,  interest and other income  decreased
to $165,256 from $279,827 for the year ended  December 31, 1999. The decrease is
attributable  to a  decrease  in cash and cash  equivalents  for the year  ended
December 31, 2000.

     Research and  development  expenses  decreased to  $3,362,841  for the year
ended December 31, 2000,  from  $4,900,521 for the year ended December 31, 1999.
The decrease is  attributable  to a decrease in clinical  trials and  laboratory
study  expenses,  and completion of the European  clinical  trial.  Research and
development expenses include laboratory study expenses,  European clinical trial
expenses,  salaries,  preparation of additional  regulatory  applications in the
United States and Europe, manufacturing of solution for trials, and consultants'
fees.

     General and  administrative  expenses  decreased to $1,779,931 for the year
ended December 31, 2000,  from  $1,896,690 for the year ended December 31, 1999.
This  decrease is  attributable  to a decrease in the general  operations of the
Company.

                                       29


Taxes

     At  December  31,  2001 the Company had a  cumulative  net  operating  loss
carryforward of approximately $37,200,000 for federal income tax purposes.

Liquidity and Capital Resources

     Since inception,  the Company has primarily financed its operations through
the sale of equity  securities,  licensing fees, and  borrowings.  During August
2001, the Company received loans of $3,350,000 through the sale of debentures to
a group of private  investors,  including  Alfred D.  Kingsley,  an investor and
consultant to the Company,  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 a 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 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.  After June 30, 2002,
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 "Securities Act").

     On March 27, 2002,  the Company  entered into a new Credit  Agreement  with
Alfred D. Kingsley under which the Company may borrow up to $300,000 for working
capital purposes. Amounts borrowed under the Credit Agreement will bear interest
at 10% per annum and will be due on March 27, 2003 or when  BioTime  receives at
least $600,000 through the sale of capital stock, loans from other lenders, fees
under licensing agreements  (excluding royalty payments),  or any combination of
those sources. Mandatory prepayments of principal will be due to the extent that
the Company  receives  funds from any one or more of those  sources in excess of
$300,000 but less than $600,000, and the amount of

                                       30


any such  mandatory  prepayments  of  principal  will reduce the maximum  amount
available  under the  Credit  Agreement  and will not be  available  for  future
borrowings.  The Company will have the right to make  voluntary  prepayments  of
principal that would  otherwise not be due,  without penalty or premium but with
accrued  interest,  at any time,  and any amounts  voluntarily  prepaid  will be
available for future borrowings,  so long as the Company is not in default under
the Credit  Agreement,  and the outstanding  principal  balance loaned under the
Credit Agreement does not exceed $300,000.

     In connection  with  entering into the Credit  Agreement on March 27, 2002,
the Company  granted  Alfred D. Kingsley a warrant to purchase  30,000 shares of
the  Company's  common  stock  at  $4.00  per  share.  The  warrants  are  fully
exercisable  and  non-forfeitable  on the date of grant and  expire on March 26,
2007.

     The following depicts BioTime's contractual  obligations as of December 31,
2001:

Obligations
                                ================================================

     At December  31,  2001,  BioTime had $ 1,652,748  of cash on hand,  and has
implemented cost savings and expenditure  limitation measures. The Company needs
additional capital and greater revenues to continue its current  operations,  to
begin  clinical  trials  of  PentaLyte,  and  to  conduct  its  planned  product
development and research programs. On March 27, 2002, the Company received a new
$300,000  line of credit.  The  Company  has also  retained  certain  investment
bankers  on a non-  exclusive  basis to assist the  Company in raising  capital.
However,  sales of additional  equity securities could result in the dilution of
the interests of present  shareholders.  The Company is also  continuing to seek
new agreements with  pharmaceutical  companies to provide product and technology
licensing fees and royalties. The availability and terms of equity financing and
new license  agreements  are  uncertain.  The  unavailability  or  inadequacy of
additional  financing or future  revenues to meet capital  needs could force the
Company to modify,  curtail, delay or suspend some or all aspects of its planned
operations.  However, management believes its existing cash and available credit
are sufficient to allow the Company to operate through December 31, 2002.

                                       31


Critical Accounting Policies and Estimates

     Management's  discussion and analysis of the Company's  financial condition
and results of operations are based on the Company's financial statements, which
have been prepared in conformity with accounting  principles  generally accepted
in the United States of America.  The preparation of these financial  statements
requires  management to make  judgments  and estimates  that affect the reported
amounts  of  assets  and  liabilities,   disclosure  of  contingent  assets  and
liabilities at the date of the financial statements, and the reported amounts of
revenues  and  expenses  during the  reporting  period.  The  Company  based its
estimates on  historical  experience  and on various other  assumptions  that it
believed to be reasonable  under the  circumstances.  Actual  results may differ
from such estimates  under  different  assumptions or conditions.  The following
summarizes the Company's critical accounting policies and significant  estimates
used in preparing its financial statements:

Debenture and Warrant Valuation

     During 2001 and in connection  with the issuance of $3,350,000 of debt, the
Company issued warrants to purchase common shares in the Company. The fair value
of the warrants was estimated using the  Black-Scholes  option pricing model and
has been  recorded  at a  discount  to the  debentures.  The  discount  is being
amortized  using the  effective  interest rate method over the term of the loan.
The  Company  may  prepay  the debt,  in whole or in part,  at any time.  If the
Company were to prepay the debt, the  unamortized  portion of the discount would
be recognized as a loss on the repayment date.

Revenue Recognition

     Under the Company's License Agreement with Abbott Laboratories, the Company
has  received  $2,500,000  of license fees based upon  achievement  of specified
milestones.  Such fees have been  recognized as revenue as the  milestones  were
achieved.  Up to  $37,500,000  of additional  license fees will be payable based
upon  annual  net sales of  Hextend,  at the rate of 10% of annual  net sales if
annual  net  sales  exceed  $30,000,000  or 5% if annual  net sales are  between
$15,000,000 and $30,000,000.  Abbott's obligation to pay licensing fees on sales
of  Hextend  will  expire on the  earlier of January 1, 2007 or, on a country by
country basis,  when all patents  protecting  Hextend in the applicable  country
expire or any third  party  obtains  certain  regulatory  approvals  to market a
generic equivalent product in that country.

     In addition to the license  fees,  Abbott will pay the Company a royalty on
total  annual  net  sales  of  Hextend.  The  royalty  rate  will  be 5% plus an
additional .22% for each $1,000,000 of annual net sales, up to a maximum royalty
rate of 36%. The royalty rate for each year will be applied on a total net sales
basis.  Abbott's  obligation to pay royalties on sales of Hextend will expire in
the  United  States  or  Canada  when  all  patents  protecting  Hextend  in the
applicable  country  expire  and any  third  party  obtains  certain  regulatory
approvals to market a generic equivalent product in that country.

     The  Company  recognizes  such  revenues  in the quarter in which the sales
report is  received,  rather than the quarter in which the sales took place,  as
the  Company  does not have  sufficient  sales  history  to  accurately  predict
quarterly sales. Revenues for the year ended December 31, 2001 include royalties
on sales made by Abbott  during the twelve  months  ended  September  30,  2001.
Royalties

                                       32


on sales made during the fourth  quarter of 2001 will not be  recognized  by the
Company  until the first  quarter of fiscal year 2002.  Royalties  on sales made
during the quarter  ended  December 31, 2001 were not material to the  Company's
financial results.

Deferred Tax Asset Valuation Allowance

     The Company records a valuation allowance to reduce its deferred tax assets
when it is more likely than not,  based upon  currently  available  evidence and
other factors, that it will not realize some portion of, or all of, the deferred
tax assets.  The  Company  bases its  determination  of the need for a valuation
allowance on an ongoing  evaluation of current evidence  including,  among other
things,  estimates of future  earnings  and the expected  timing of deferred tax
asset  reversals.  The Company  charges or credits  adjustments to the valuation
allowance to income tax expense in the period in which these  determinations are
made.  If the Company  determines  that it would be able to realize its deferred
tax assets in the future in excess of its net recorded amount,  an adjustment to
the deferred tax asset would  increase  income in the period this  determination
was  made.  Likewise,  if the  Company  determines  that it would not be able to
realize all or part of its net  deferred  tax assets in the future,  the Company
would charge to operations an adjustment to the deferred tax asset in the period
this determination was made.

Recently Issued Accounting Standards

     Derivative  instruments  and hedging  activities - On January 1, 2001,  the
Company  adopted  Statement of  Financial  Accounting  Standards  No. 133 ("SFAS
133"), "Accounting for Derivative Instruments and Hedging Activities." SFAS 133,
as  amended,  requires  that  every  derivative  instrument,  including  certain
derivative  instruments embedded in other contracts,  be recorded on the balance
sheet at its fair value.  Changes in the fair value of derivatives  are recorded
each period in current  earnings or other  comprehensive  income,  depending  on
whether a derivative is designated as part of a hedge transaction and, if it is,
the type of hedge transaction.  SFAS 133, as amended,  requires that the Company
formally document,  designate, and assess the effectiveness of transactions that
receive hedge accounting.  The Company adopted SFAS 133, as amended,  on January
1, 2001 and did not elect hedge  accounting as defined by SFAS 133. The adoption
of this  statement  did not have a material  impact on the  Company's  financial
position or results of operations.

     Business combinations and goodwill - In June 2001, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 141 (SFAS
141"),  "Business  Combinations" and Statement of Financial Accounting Standards
No. 142 ("SFAS 142"),  "Goodwill and Other Intangible Assets." SFAS 141 requires
that all business  combinations  initiated  after June 30, 2001 be accounted for
under the purchase method and addresses the initial  recognition and measurement
of goodwill and other intangible assets acquired in a business combination. SFAS
141 addresses  the initial  recognition  and  measurement  of intangible  assets
acquired  outside of a business  combination and the accounting for goodwill and
other intangible assets subsequent to their acquisition.  SFAS 142 provides that
intangible  assets with finite  useful lives be amortized  and that goodwill and
intangible  assets with indefinite lives will not be amortized,  but will rather
be tested

                                       33


at least  annually  for  impairment.  The Company will adopt SFAS 141 and 142 on
January 1, 2002. The adoption of this statement will not have a material  impact
on the financial statements.

     Impairment  and  disposal  of long  lived  assets - In  October  2001,  the
Financial  Accounting  Standards Board issued Statement of Financial  Accounting
Standards No. 144 ("SFAS 144"),  "Accounting  for the  Impairment or Disposal of
Long-Lived Assets." SFAS 144 supersedes SFAS 121, "Accounting for the Impairment
of  Long-Lived  Assets and for  Long-Lived  Assets to be  Disposed  Of," and the
accounting and reporting  provisions of Accounting  Principles Board Opinion No.
30,  "Reporting  the Results of Operations - - Reporting the Effects of Disposal
of  a  Segment  of a  Business,  and  Extraordinary,  Unusual  and  Infrequently
Occurring  Events and  Transactions,  " and addresses  financial  accounting and
reporting for the impairment of disposal of long-lived  assets. The Company will
adopt SFAS 144 on January 1, 2002.  The adoption of this statement will not have
a material impact on the financial statements.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders
BioTime, Inc.:

We have audited the accompanying balance sheets of BioTime,  Inc. (a development
stage company) as of December 31, 2001 and 2000,  and the related  statements of
operations,  shareholders'  equity  (deficit) and cash flows for the years ended
December  31,  2001,  2000,  and 1999,  and the period  from  November  30, 1990
(inception)  to  December  31,  2001.   These   financial   statements  are  the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our  opinion,  such  financial  statements  present  fairly,  in all material
respects,  the financial  position of BioTime,  Inc. as of December 31, 2001 and
2000,  and the results of its  operations and its cash flows for the years ended
December  31,  2001,  2000 and 1999,  and the  period  from  November  30,  1990
(inception)  to December 31, 2001,  in  conformity  with  accounting  principles
generally accepted in the United States of America.

The Company is in the development stage as of December 31, 2001. As discussed in
Note 1 to the  financial  statements,  successful  completion  of the  Company's
product  development  program and,  ultimately,  the  attainment  of  profitable
operations  is dependent  upon future  events,  including  maintaining  adequate
financing to fulfill its development  activities,  obtaining regulatory approval
for products ultimately developed, and achieving a level of revenues adequate to
support the Company's cost structure.

                          NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

General - BioTime,  Inc.  (the  Company)  was  organized  November 30, 1990 as a
California corporation.  The Company is a biomedical organization,  currently in
the  development  stage,  which is engaged in the  research and  development  of
synthetic  plasma  expanders,  blood  volume  substitute  solutions,  and  organ
preservation  solutions,  for use in  surgery,  trauma  care,  organ  transplant
procedures, and other areas of medicine.

Development Stage Enterprise - Since inception,  the Company has been engaged in
research and  development  activities  in  connection  with the  development  of
synthetic  plasma  expanders,   blood  volume  substitute  solutions  and  organ
preservation  products.  The  Company  has limited  operating  revenues  and has
incurred net losses of  $30,770,238  from  inception  to December 31, 2001.  The
successful   completion  of  the  Company's  product  development  program  and,
ultimately,  achieving  profitable  operations  is dependent  upon future events
including  maintaining  adequate  capital  to  finance  its  future  development
activities,  obtaining  regulatory  approvals  for the  products it develops and
achieving a level of revenues adequate to support the Company's cost structure.

The Company's  operations are subject to a number of factors that can affect its
operating  results and  financial  condition.  Such factors  include but are not
limited to the  following:  the  results  of  clinical  trials of the  Company's
products;   the  Company's  ability  to  obtain  United  States  Food  and  Drug
Administration  and  foreign   regulatory   approval  to  market  its  products;
competition  from  products  manufactured  and sold or being  developed by other
companies;  the price of and demand for Company products;  the Company's ability
to obtain  additional  financing and the terms of any such financing that may be
obtained;  the  Company's  ability to  negotiate  favorable  licensing  or other
manufacturing  and marketing  agreements for its products;  the  availability of
ingredients   used  in  the  Company's   products;   and  the   availability  of
reimbursement  for the cost of the Company's  products  (and related  treatment)
from  government  health  administration  authorities,  private health  coverage
insurers and other organizations.

Certain  Significant Risks and Uncertainties - At December 31, 2001, BioTime had
$ 1,652,748 of cash on hand, and has  implemented  cost savings and  expenditure
limitation  measures.  The Company needs additional capital and greater revenues
to continue its current operations,  to begin clinical trials of PentaLyte,  and
to conduct its planned product  development and research programs.  On March 27,
2002,  the  Company  received a new  $300,000  line of credit  (see Note 9). The
Company has also retained certain investment bankers on a non-exclusive basis to
assist the  Company in raising  capital.  However,  sales of  additional  equity
securities   could  result  in  the   dilution  of  the   interests  of  present
shareholders.  The  Company  is also  continuing  to seek  new  agreements  with
pharmaceutical  companies to provide  product and technology  licensing fees and
royalties.  The  availability  and terms of  equity  financing  and new  license
agreements  are  uncertain.  The  unavailability  or  inadequacy  of  additional
financing or future  revenues to meet  capital  needs could force the Company to
modify, curtail, delay or suspend some or all aspects of its planned operations.
However,  management  believes  its  existing  cash  and  available  credit  are
sufficient to allow the Company to operate through December 31, 2002.

                                       44


2. SIGNIFICANT ACCOUNTING POLICIES

Financial  Statement  Estimates - The  preparation  of financial  statements  in
conformity with generally accepted accounting  principles requires management to
make estimates and  assumptions  that affect the reported  amounts of assets and
liabilities  and disclosure of contingent  assets and liabilities at the date of
the  financial  statements  and the  reported  amounts of revenues  and expenses
during the reporting period. Such management estimates include certain accruals.
Actual results could differ from those estimates.

Revenue recognition - In April 1997, BioTime and Abbott Laboratories  ("Abbott")
entered into an Exclusive  License  Agreement  (the "License  Agreement")  under
which BioTime  granted to Abbott an exclusive  license to  manufacture  and sell
BioTime's  proprietary  blood plasma  volume  expander  solution  Hextend in the
United States and Canada for certain therapeutic uses.

Under the License  Agreement,  Abbott has paid the Company $2,500,000 of license
fees  based  upon  achievement  of  specified  milestones.  Such  fees have been
recognized as revenue as the  milestones  were  achieved.  Up to  $37,500,000 of
additional  license fees will be payable  based upon annual net sales of Hextend
at the rate of 10% of annual net sales if annual net sales exceed $30,000,000 or
5% if  annual  net sales  are  between  $15,000,000  and  $30,000,000.  Abbott's
obligation to pay license fees on sales of Hextend will expire on the earlier of
January 1, 2007 or, on a country by country basis,  when all patents  protecting
Hextend in the  applicable  country  expire or any third party  obtains  certain
regulatory approvals to market a generic equivalent product in that country.

In addition to the license fees, Abbott will pay the Company a royalty on annual
net sales of Hextend.  The royalty rate will be 5% plus an  additional  .22% for
each increment of $1,000,000 of annual net sales,  up to a maximum  royalty rate
of 36%. Abbott's  obligation to pay royalties on sales of Hextend will expire in
the  United  States  or  Canada  when  all  patents  protecting  Hextend  in the
applicable  country  expire  and any  third  party  obtains  certain  regulatory
approvals to market a generic equivalent product in that country.

The Company recognizes such revenues in the quarter in which the sales report is
received,  rather than the quarter in which the sales took place, as the Company
does not have sufficient  sales history to accurately  predict  quarterly sales.
Revenues for the year ended December 31, 2001 include royalties on sales made by
Abbott  during the twelve months ended  September  30, 2001.  Royalties on sales
made  during the fourth  quarter of 2001 will not be  recognized  by the Company
until the first quarter of fiscal year 2002.  Royalties on sales made during the
quarter  ended  December  31,  2001 were not  material  to  BioTime's  financial
results.

Abbott has agreed that the Company may convert Abbott's  exclusive  license to a
non-exclusive  license or may terminate the license  outright if certain minimum
sales and  royalty  payments  are not met.  In order to  terminate  the  license
outright,  BioTime  would pay a  termination  fee in an amount  ranging from the
milestone  payments  made by Abbott to an amount equal to three times prior year
net sales, depending upon when termination occurs.  Management believes that the
probability of payments of any termination fee by the Company is remote.

Cash and cash equivalents - The Company considers all highly liquid  investments
purchased  with  an  original  maturity  of  three  months  or  less  to be cash
equivalents.

Concentration of credit risk - Financial  instruments  that potentially  subject
the Company to significant  concentrations  of credit risk consist  primarily of
cash and cash  equivalents.  The Company limits the amount of credit exposure of
cash  balances by  maintaining  its  accounts in high credit  quality  financial
institutions.

                                       45


Equipment is stated at cost or, in the case of donated equipment, at fair market
value.  Equipment is being  depreciated  using the  straight-line  method over a
period of thirty-six to eighty-four months.

Patent costs  associated with obtaining  patents on products being developed are
expensed as research and development expenses when incurred. These costs totaled
$343,501,  $215,424 and $160,221 for the years ended December 31, 2001, 2000 and
1999, respectively,  and cumulatively,  $1,220,209 for the period from inception
(November 30, 1990) to December 31, 2001.

Research  and   development   costs  are  expensed  when  incurred  and  consist
principally of salaries,  payroll taxes,  research and laboratory fees, hospital
and  consultant  fees related to clinical  trials,  and the Company's  PentaLyte
solution for use in human clinical trials.

Income  Taxes - The  Company  accounts  for  income  taxes  in  accordance  with
Statement of Financial  Accounting  Standards  No. 109,  "Accounting  for Income
Taxes,"  which  prescribes  the use of the asset and  liability  method  whereby
deferred tax asset or liability  account  balances are calculated at the balance
sheet date using current tax laws and rates in effect.  Valuation allowances are
established  when necessary to reduce deferred tax assets when it is more likely
than not that a portion or all of the deferred tax assets will not be realized.

Stock-based  compensation  - The Company grants stock options for a fixed number
of shares to  employees  with an  exercise  price equal to the fair value of the
shares at the date of grant.  The  Company  accounts  for  employee  stock-based
compensation in accordance with Accounting Principles Board Opinion No. 25 ("APB
25"),  "Accounting  for Stock  Issued to  Employees."  The Company  accounts for
stock-based  awards to  nonemployees  in accordance  with Statement of Financial
Accounting   Standards  No.  123  ("SFAS  123"),   "Accounting  for  Stock-Based
Compensation" and Emerging Issues Task Force (EITF) Issue No. 96-18, "Accounting
for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or
in Conjunction with Selling, Goods, or Services."

Stock split - In October 1997, the Company effected a three-for-one split of its
common shares. All share and per share amounts have been restated to reflect the
stock split for all periods presented.

Net Loss per share - Basic net loss per share is computed  by dividing  net loss
available  to  common  stockholders  by  the   weighted-average   common  shares
outstanding   for  the  period.   Diluted  net  loss  per  share   reflects  the
weighted-average common shares outstanding plus the potential effect of dilutive
securities or contracts  which are convertible to common shares such as options,
warrants,  convertible  debt,  and  preferred  stock (using the  treasury  stock
method) and shares issuable in future periods,  except in cases where the effect
would be anti-dilutive.  Diluted loss per share for the years ended December 31,
2001,  2000, and 1999 exclude any effect from such securities as their inclusion
would be antidilutive.

Comprehensive  Loss -  Statement  of  Financial  Accounting  Standards  No. 130,
"Reporting  Comprehensive  Income,"  establishes  standards  for  reporting  and
displaying comprehensive income and its components (revenues,  expenses,  gains,
and losses) in a full set of general-purpose financial statements. Comprehensive
loss was the same as net loss for all periods presented.

                                       46


Fair value of  financial  instruments  - The  carrying  amount of the  Company's
long-term debt (debentures) approximates its fair value.

Segment  information - The Company  operates in the single  segment of producing
aqueous based synthetic solutions used in medical  applications and is currently
in the development stage of this segment.

Derivative  instruments and hedging activities - On January 1, 2001, the Company
adopted  Statement  of  Financial  Accounting  Standards  No. 133 ("SFAS  133"),
"Accounting  for Derivative  Instruments and Hedging  Activities."  SFAS 133, as
amended, requires that every derivative instrument, including certain derivative
instruments embedded in other contracts, be recorded on the balance sheet at its
fair value. Changes in the fair value of derivatives are recorded each period in
current  earnings  or  other  comprehensive  income,   depending  on  whether  a
derivative is designated as part of a hedge  transaction and, if it is, the type
of hedge transaction.  SFAS 133, as amended,  requires that the Company formally
document,  designate,  and assess the effectiveness of transactions that receive
hedge accounting.  The Company adopted SFAS 133, as amended,  on January 1, 2001
and did not elect hedge  accounting as defined by SFAS 133. The adoption of this
statement did not have a material impact on the Company's  financial position or
results of operations.

Business  combinations  and goodwill - In June 2001,  the  Financial  Accounting
Standards Board issued Statement of Financial Accounting Standards No. 141 (SFAS
141"),  "Business  Combinations" and Statement of Financial Accounting Standards
No. 142 ("SFAS 142"),  "Goodwill and Other Intangible Assets." SFAS 141 requires
that all business  combinations  initiated  after June 30, 2001 be accounted for
under the purchase method and addresses the initial  recognition and measurement
of goodwill and other intangible assets acquired in a business combination. SFAS
141 addresses  the initial  recognition  and  measurement  of intangible  assets
acquired  outside of a business  combination and the accounting for goodwill and
other intangible assets subsequent to their acquisition.  SFAS 142 provides that
intangible  assets with finite  useful lives be amortized  and that goodwill and
intangible  assets with indefinite lives will not be amortized,  but will rather
be tested at least annually for impairment.  The Company will adopt SFAS 141 and
142 on January 1, 2002.  The adoption of this statement will not have a material
impact on the financial statements.

Impairment  and disposal of long lived assets - In October  2001,  the Financial
Accounting  Standards Board issued Statement of Financial  Accounting  Standards
No. 144 ("SFAS 144"),  "Accounting  for the Impairment or Disposal of Long-Lived
Assets."  SFAS 144  supersedes  SFAS  121,  "Accounting  for the  Impairment  of
Long-Lived  Assets  and  for  Long-Lived  Assets  to be  Disposed  Of,"  and the
accounting and reporting  provisions of Accounting  Principles Board Opinion No.
30,  "Reporting  the Results of Operations - - Reporting the Effects of Disposal
of  a  Segment  of a  Business,  and  Extraordinary,  Unusual  and  Infrequently
Occurring  Events and  Transactions,  " and addresses  financial  accounting and
reporting for the impairment of disposal of long-lived  assets. The Company will
adopt SFAS 144 on January 1, 2002.  The adoption of this statement will not have
a material impact on the financial statements.

3. LINE OF CREDIT AND DEBENTURES

During March,  2001,  BioTime  entered into a one year  Revolving Line of Credit
Agreement  (the "Credit  Agreement")  with Alfred D.  Kingsley,  an investor and
consultant to the Company, under which BioTime could borrow up to $1,000,000 for
working capital  purposes at an interest rate of 10% per annum. In consideration
for making the line of credit  available,  the company issued to Mr.  Kingsley a
fully vested  warrant to purchase  50,000 common shares at an exercise  price of
$8.31.  The fair value of this  warrant of  $254,595  was  determined  using the
Black-Scholes pricing model with the following assumptions:  contractual life of
5  years;  risk-free  interest  rate of  5.50%;  volatility  of  87.55%;  and no
dividends  during the  expected  term.  The fair value amount of the warrant was
recorded as deferred financing costs and was being amortized to interest expense
over the term of the Credit Agreement.

In August 2001,  the company  issued  $3,350,000  of  debentures  to an investor
group.  As part of the $3,350,000  debenture  issuance,  Mr.  Kingsley agreed to
convert the $1,000,000 current outstanding balance under the Credit Agreement to
$1,000,000 of debentures and purchased an additional  $500,000 of debentures for
cash. On the date of the conversion of the Credit  Agreement to the  debentures,
the Credit Agreement was terminated,  and no additional borrowings are available
under the Credit  Agreement.  Interest on the debentures is payable at an annual
rate of 10% and is payable semi-annually. The principal amount of the debentures
is due 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 revenue
(excluding interest and dividends) it collects for the quarter. This restriction
will expire when the Company  obtains at least  $5,000,000 in cash through sales
of equity securities or pays off the debenture indebtedness in full. The Company
has also agreed not to pay any cash  dividends on or to redeem or repurchase any
of its common shares outstanding until it has paid off the debentures in full.

Investors  who  purchased the  debentures  also received  warrants to purchase a
total of 515,385  common  shares at an  exercise  price of $6.50.  The  warrants
expire on August 1, 2004. The total fair value of the warrants of $1,596,124 was
determined  using the  Black-Scholes  option  pricing  model with the  following
assumptions:  contractual  life of 3 years;  risk-free  interest  rate of 4.04%;
volatility of 88%; and no dividends  during the expected term. Of the $3,350,000
of  proceeds  $1,596,124  was  allocated  to the  warrants  which  includes  the
unamortized  portion  ($159,122)  of the fair  value of the  warrant  issued  in
connection with the Credit Agreement.  The portion of the proceeds  allocated to
the  debentures  is being  accreted  to  interest  expense  over the term of the
debentures using the effective  interest rate method.  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 equals or exceeds 150% of the
exercise price for fifteen consecutive trading days.

4. SHAREHOLDERS' EQUITY

During June 1994, the Board of Directors authorized  management to repurchase up
to  200,000  of the  Company's  common  shares  at  market  price at the time of
purchase.  A total of 90,800 shares have been repurchased and retired. No shares
have been repurchased since August 28, 1995.

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, who are also shareholders of the Company. Under
this agreement the Company issued to the financial advisor warrants

                                       48


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.

Greenbelt  has  purchased  544,730  Common  Shares by  exercising  some of those
warrants at prices ranging from $1.93 to $2.35 per share. Greenbelt continues to
hold warrants,  expiring during April and June 2002, to purchase an aggregate of
155,636  Common  Shares at prices  ranging  from  $13.75  to  $15.74.  The other
warrants  have expired  unexercised.  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.

During  September 1996, the Company entered into an agreement with an individual
to act as an advisor to the Company. In exchange for services, as defined, to be
rendered by the advisor  through  September  1999, the Company issued  warrants,
with five year terms, to purchase  124,510 common shares at a price of $6.02 per
share. 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.  Warrants for 77,775 common shares vested
and became exercisable and transferable when issued;  warrants for the remaining
46,735  common  shares  vested  ratably   through   September  1997  and  became
exercisable  and  transferable as vesting  occurred.  The estimated value of the
services to be performed is $60,000 and that amount has been  amortized over the
three year term of the agreement.

On  February 5, 1997,  the Company  completed  a  subscription  rights  offering
raising $5,662,180, through the sale of 849,327 common shares.

During  April 1998,  the Company  entered  into a  financial  advisory  services
agreement with Greenbelt Corp. The agreement  provided for an initial payment of
$90,000  followed  by an  advisory  fee of  $15,000  per  month  that  was  paid
quarterly.  On August 11, 2000, the Board of Directors  approved the renewal and
amendment of this agreement for a period of twelve months ending March 31, 2001.
Under the amended  agreement,  Greenbelt Corp.  received 30,000 common shares in
four  quarterly  installments  of 7,500  shares each.  On January 16, 2002,  the
agreement  was renewed and amended to provide for the issuance of 40,000  common
shares  payable in quarterly  installments  of 10,000  ending on March 31, 2002.
Under the agreement,  upon the request of Greenbelt Corp., the Company will file
a  registration  statement to register  the shares for public sale.  The Company
recognized  $299,175  and  $105,000  of stock  compensation  expense  (general &
administrative) during the years ended December 31, 2001 and 2000, respectively,
under the agreement.

On March 9, 1999, the Company  completed a subscription  rights offering raising
$7,328,626, through the sale of 751,654 common shares.

On July 15, 1999, the Company  established the "BioTime  Endowment for the Study
of Aging and Low- Temperature  Medicine" (the  "Endowment") at the University of
California at Berkeley.  The endowment  will support the research  activities of
faculty and researchers in the areas of aging and low temperature medicine.  The
initial term of the Endowment shall be for ten years,  and upon review,  renewed
every five years

                                       49


thereafter.  The Company funded the Endowment with $65,000 in cash and a warrant
to the  University to purchase  40,000 of the Company's  common shares for $0.50
per share.  On September  23, 1999,  the  University  of  California at Berkeley
exercised  its  warrant  for  40,000  shares.  The fair  value  of the  warrant,
estimated  to  be  approximately   $552,000,  was  recognized  in  research  and
development expenses during the year ended December 31, 1999.

5. STOCK OPTION PLAN

The Board of  Directors  of the Company  adopted the 1992 Stock Option Plan (the
"Plan") during  September 1992. The Plan was approved by the shareholders at the
1992 Annual  Meeting of  Shareholders  on December 1, 1992.  Under the Plan,  as
amended,  the Company has reserved  1,800,000  common shares for issuance  under
options  granted to eligible  persons.  No options may be granted under the Plan
more  than ten  years  after  the date the  Plan  was  adopted  by the  Board of
Directors,  and no options  granted  under the Plan may be  exercised  after the
expiration  of ten years  from the date of grant.  Under  the Plan,  options  to
purchase  common  shares may be  granted to  employees,  directors  and  certain
consultants  at prices not less than the fair market  value at date of grant for
incentive  stock  options and not less than 85% of fair  market  value for other
stock options. These options expire five to ten years from the date of grant and
may be fully  exercisable  immediately,  or may be  exercisable  according  to a
schedule  or  conditions  specified  by the  Board of  Directors  or the  Option
Committee.  During the years ended December 31, 2001,  2000 and 1999,  employees
and directors were granted options to purchase 80,000,  48,000 and 33,000 common
shares, respectively, and non-employees were granted options to purchase 50,000,
1,500 and 63,000 shares, respectively. At December 31, 2001, 439,000 shares were
available for future grants under the Option Plan.

Options to purchase  60,000 common shares,  granted to consultants in 1999, vest
upon achievement of certain  milestones.  At December 31, 2001, 5000 options had
vested and 55,000 had not vested.  The Company is  amortizing  into research and
development  expense  the  estimated  fair  value of such  options,  subject  to
remeasurement at the end of each reporting period,  over the period estimated to
achieve such milestones (one to two years).  During 2001 the Company  recorded a
benefit  of  $132,249  as a result of the  remeasurement  of such  options.  The
Company recorded $203,229 and $171,027 as compensation  expense related to these
options  during the years ended  December 31, 2000 and 1999,  respectively.  The
Company has $112,166 in unamortized  compensation  expense at December 31, 2001.
The Company's estimate of compensation cost at December 31, 2001 is based on the
Black-Scholes option pricing model with the following  assumptions:  contractual
life of 7 years;  risk-free  interest  rate of 5.09%;  volatility of 73%; and no
dividends during the expected term.

Option activity under the Plan is as follows:


                                                                                               Weighted

6. COMMITMENTS AND CONTINGENCIES

The  Company  has an  employment  agreement  with  one  officer  who  is  also a
shareholder,  for a five-year term,  which expires in April 2002. This agreement
provides for a base salary with annual  increases.  The agreement  also provides
that  in  the  event  the  officer's  employment   terminates,   voluntarily  or
involuntarily,  after a change in control of the Company  through an acquisition
of voting stock or assets, or a merger or consolidation with another corporation
or entity,  the  officer  will be entitled to  severance  payments  equal to the
greater of (a) 2.99 times the average annual compensation for the preceding five
years or (b) the  balance of the base  salary for the  unexpired  portion of the
term  of the  employment  agreement.  This  officer/shareholder  has  signed  an
intellectual property agreement with the Company as a condition of employment.

The Company occupies its office and laboratory facility in Berkeley,  California
under a lease that will expire on March 31, 2004. The Company presently occupies
approximately 8,890 square feet of space with a

                                       52


monthly rent of $11,024.  The rent  increases  annually by the greater of 3% and
the  increase in the local  consumer  price index,  subject to a maximum  annual
increase  of 7%. Due to an increase  in the local  consumer  price index of only
1.8% over the period defined in the lease agreement, rent will only be increased
by the minimum  amount of 3% (yielding a new rent,  payable  beginning  with the
month of April, 2002, of $11,355).  Rent expense totaled $122,096,  $113,600 and
$91,796 for the years ended December 31, 2001, 2000 and 1999, respectively.

No tax benefit has been  recorded  through  December 31, 2001 because of the net
operating losses incurred and a full valuation allowance  provided.  A valuation
allowance  is provided  when it is more likely than not that some portion of the
deferred  tax  asset  will  not be  realized.  The  Company  established  a 100%
valuation  allowance  for  all  periods  presented  due  to the  uncertainty  of
realizing  future tax benefits from its net  operating  loss  carryforwards  and
other deferred tax assets.

As of December 31, 2001,  the Company has net operating  loss  carryforwards  of
approximately  $37,200,000  for federal and  $18,000,000 for state tax purposes,
which  begin to expire  during  fiscal  years  2005 and 2001,  respectively.  In
addition,  the  Company has tax credit  carryforwards  for federal and state tax
purposes of $778,682 and $445,383,  respectively,  which will begin to expire in
2005.

Internal  Revenue  Code  Section  382  places a  limitation  (the  "Section  382
Limitation")  on the  amount  of  taxable  income  which  can be  offset  by net
operating  loss  ("NOL")  carryforwards  after a change  in  control  (generally
greater than 50% change in  ownership)  of a loss  corporation.  California  has
similar rules.  Generally,  after a control change,  a loss  corporation  cannot
deduct NOL  carryforwards in excess of the Section 382 Limitation.  Due to these
"change in ownership" provisions, utilization of the NOL and tax credit

                                       53


carryforwards may be subject to an annual limitation regarding their utilization
against taxable income in future periods.

8. RELATED PARTY TRANSACTIONS

During the years ended December 31, 2000 and 1999, fees for consulting  services
of  $5,500  and  $19,125,  respectively,  were  paid to a member of the Board of
Directors. No consulting fees were paid to any members of the Board of Directors
during the year ended December 31, 2001.

9. SUBSEQUENT EVENTS

On March 27, 2002, BioTime entered into a new Revolving Line of Credit Agreement
(the "Credit  Agreement") with Alfred D. Kingsley under which BioTime may borrow
up to $300,000 for working capital  purposes.  Amounts borrowed under the Credit
Agreement  will be due on  March  31,  2003 or when  BioTime  receives  at least
$600,000 through the sale of capital stock, loans from other lenders, fees under
licensing agreements  (excluding royalty payments),  or any combination of those
sources.  Interest on borrowings  shall accrue at a rate of 10% per annum and is
payable with principal on the maturity date. Mandatory  prepayments of principal
will be due to the extent that the Company  receives  funds from any one or more
of those sources in excess of $300,000 but less than $600,000.

In connection  with entering  into the Credit  Agreement on March 27, 2002,  the
Company  granted  Alfred D. Kingsley a warrant to purchase  30,000 shares of the
Company's  common stock at $4.00 per share.  The warrants are fully  exercisable
and non-forfeitable on the date of grant and expire on March 26, 2007.

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 has an employment  agreement  with Ronald S. Barkin,
President,  that will expire on March 31, 2002.  Mr. Barkin will not continue as
President after termination of his employment agreement.  The executive officers
were entitled to receive annual salaries of $163,000 for the year ended December
31, 2001, but in July, 2001 Drs.  Segall,  Sternberg and Waitz and Judith Segall
agreed to participate in the Company's voluntary salary reduction program. Since
these voluntary  salary  reductions went into effect,  Dr. Segall has received a
salary of $3,000 per month and Drs.  Sternberg  and Waitz and Judith Segall have
easch received a salary of $6,000 per month. 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.

     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.

     The  following  table  summarizes   certain   information   concerning  the
compensation paid to the five most highly compensated  executive officers during
the last three full fiscal years.

Insider Participation in Compensation Decisions

     The Board of  Directors  does not have a standing  Compensation  Committee.
Instead,  the Board of Directors as a whole and the Audit Committee  approve 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.  None of the  members  of the  Audit
Committee are employees of the Company.

Stock Options

     Of the five most highly compensated executive officers of the Company, only
Ronald S. Barkin held any stock  options  during the fiscal year ended  December
31, 2001. The following table certain information  concerning Mr. Barkin's stock

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.

                                       59


     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.  Greenbelt  continues  to hold  warrants,
expiring  during April and June 2002, to purchase an aggregate of 155,636 Common
Shares at price ranging from $13.75 to $15.74.  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 twice and will expire on March 31, 2002,  but instead
of paying cash compensation, 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, and 40,000 Common Shares in four quarterly installments of
10,000 each for the twelve months ended March 31, 2002.

     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
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.

                                       60


     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").

     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.  The Company also included in the registration  300,000 Common Shares
the Mr. Kingsley acquired during December 2000 from certain BioTime officers and
directors.  The  Company  paid the  expenses  of  registration,  but will not be
obligated to pay any underwriting  discounts or commissions that may be incurred
by Greenbelt,  Mr.  Kingsley,  or Mr. Dresner in connection with any sale of the
warrants or Common Shares.

     During March 2002,  the Company  entered into a new Credit  Agreement  with
Alfred D. Kingsley. 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.  The Company has agreed to register the
shares  issuable  under the warrant  for sale under the Act,  upon  request,  on
substantially  the same terms as the  registration  of the warrants issued under
the Company's consulting agreement with Greenbelt.
