                                     PART I


Item 1.  Description of Business

Overview

         BioTime Inc. is a development stage company engaged in the research and
development  of aqueous  based  synthetic  solutions  that can be used as plasma
expanders,  blood substitutes during hypothermic (low temperature)  surgery, and
organ preservation solutions.  These products are intended for several important
medical  applications,  including:  the emergency treatment of blood loss due to
traumatic  injury  or  during  surgery;   cardiopulmonary  bypass  surgery;  the
replacement of very large volumes of a patient's  blood during  cardiac  surgery
and  neurosurgery  that  involve  lowering the  patient's  body  temperature  to
hypothermic  levels;  the  preservation  of body  organs  and  tissues  awaiting
transplant;  cancer treatment;  and other biomedical  applications.  Because the
Company's  solutions are synthetic,  rather than human blood byproducts,  use of
the solutions would not pose the risk of transmitting  AIDS,  hepatitis or other
blood borne infectious diseases, and would not have to be matched to a patient's
blood type.

         The Company's first two blood  replacement  products are Hextend(R) and
PentaLyte,TM   which  are   composed   of   different   hydroxyethyl   starches,
electrolytes,  sugar and a buffer.  The Company  believes  that a solution  that
sustains  the  patient's  fluid  volume  and  physiological   balance,   thereby
maintaining  tissue and organ  function,  can reduce or  eliminate  the need for
supplemental  whole  blood and  blood  plasma.  Based  upon the  results  of its
laboratory research,  the Company has determined that in many emergency care and
surgical  applications,  it is not necessary for the solution to include special
oxygen carrying molecules to replace red blood cells. Therefore, the Company has
devoted its efforts to the development of formulations that do not rely upon the
use  of  recombinant  DNA  or  other  complex  technologies  to  synthesize  and
assimilate into solution costly and potentially toxic oxygen carrying  molecules
such as hemoglobin and perfluorocarbons.

         The Company has filed an Investigational  New Drug Application  ("IND")
with the Food and Drug  Administration  ("FDA") and has received  permission  to
commence Phase III clinical trials of Hextend(R) in approximately  125 patients.
These  Phase  III  clinical  trials  are  designed  to test  whether  the use of
Hextend(R)  can improve  patient  outcomes by  maintaining  organ  perfusion and
preventing  the adverse  effects of  hypovolemia  (loss of blood volume)  during
surgical  procedures  that often  involve a large  amount of blood  loss.  It is
expected  that  Hextend(R)  will be tested in a variety of surgical  procedures,
such as  orthopedic,  urologic and  gastro-intestinal  surgery.  These  clinical
trials are  expected  to begin in October  1996 at the Duke  University  Medical
Center in Durham,  North Carolina.  Although BioTime has conducted  pharmacology
and toxicology  testing of Hextend,(R) and has compiled a significant  amount of
data  demonstrating the safety and efficacy of Hextend(R) in laboratory  testing
using  animal  subjects,  the outcome of human trials  cannot be predicted  with
certainty.

         The time  frame in  which  the  Company  will be able to  complete  the
clinical  testing  necessary  and file a New Drug  Application  ("NDA")  for FDA
approval  depends in part upon the ability of the  Company to obtain  sufficient
financing for that purpose, as well as a manufacturer willing to produce

                                        2

<PAGE>



Hextend(R) in compliance with FDA "good manufacturing practices." The Company is
seeking  to  obtain  the  necessary  financing  from one or more  pharmaceutical
companies  that would be  capable of  manufacturing  Hextend(R)  for  commercial
distribution when FDA approval is obtained.  See "Manufacturing" and "Government
Regulation."

         To reduce  the  capital  costs and  delays  inherent  in  acquiring  or
establishing  a  pharmaceutical   manufacturing   facility  and  establishing  a
marketing  organization,  the Company  will seek  contract,  licensing  or joint
venture  arrangements  with  one  or  more  pharmaceutical   companies  for  the
production and marketing of the Company's products.  If such arrangements cannot
be made on acceptable  terms, the Company would be required to obtain additional
capital to construct or acquire its own  manufacturing  facilities and establish
its own marketing organization.  There is no assurance that the Company would be
able to raise sufficient capital for those purposes.

         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.


The Market for Plasma Expanders, Blood Substitutes and Organ Preservation
 Solutions

         The  transfusion  of human  blood or blood  products is  presently  the
traditional  and  only  commercially   available  means  for  treating  patients
suffering from severe blood loss  requiring the  replacement of more than 30% of
their blood volume.  The transfusion market in the United States consists of two
principal segments. The acute blood loss segment, which comprises  approximately
60  percent  of  the  transfusion  market,  includes  transfusions  required  in
connection  with trauma,  surgery and  unexpected  blood loss. The chronic blood
loss  segment  represents  approximately  40 percent of the  transfusion  market
includes  transfusions  in  connection  with general  medical  applications  and
chronic anemias.  Approximately 14 million units of blood were transfused in the
United  States  in  1992,  of  which   approximately   8.5  million  units  were
administered  to patients  suffering  the  effects of acute blood loss.  Patient
charges  for the  units  of  blood  used in the  United  States  in 1992 for the
treatment of acute blood loss were approximately $2.5 billion.

         The use of whole  blood or human  blood  products  presents a number of
medical risks and  logistical  problems that could be reduced or eliminated if a
safe and effective synthetic plasma expander or blood substitute were available.
Transfused  blood can only be used in recipients  having a blood type compatible
with that of the donor.  Delays in  treatment  resulting  from the  necessity of
blood typing prior to transfusion, together with the limited shelf life of blood
and the limited  availability of certain blood types,  impose constraints on the
rapid  availability  of  compatible  blood for  transfusion.  Accident  victims,
wounded  soldiers  and  persons  with rare  blood  types may die while  awaiting
compatible blood. In addition, clerical error continues to result in transfusion
related deaths.  The problem of blood type  compatibility and availability could
be eliminated by the use of a universally  compatible  synthetic blood plasma. A
synthetic  product  with  a long  shelf  life  that  could  be  stored  at  room
temperature  would  also  resolve  problems  of  perishability  of  whole  blood
products.

         The past decade has seen an increase in the  incidence  of  blood-borne
infectious diseases, such

                                      3

<PAGE>



as AIDS and  hepatitis B, C, D, E, and F which has  heightened  the awareness of
both  health  professionals  and  patients  to  the  inherent  risk  from  blood
transfusions.  Although  new tests  have been  developed,  such  tests  have not
entirely eliminated the risk of infectious blood-borne disease transmission.  In
addition,  despite improved testing standards,  human error still results in the
release of contaminated units of blood.  Furthermore,  some infectious  diseases
are known to  contaminate  the blood  supply but  cannot be  avoided  because no
reliable or cost effective  diagnostic  tests exist.  New infectious  agents can
suddenly appear in the blood supply, and it can take years to develop a reliable
test for such agents.  Several years elapsed  between the appearance of AIDS and
the development of a reliable test, and numerous  patients  contracted AIDS from
transfusions  during that time. A synthetic blood plasma or blood substitute not
derived from human blood products would be advantageous because it could be used
without exposing the patient to the risk of infection by a blood-borne disease.

         The  current  blood  supply  is  dependent   upon   volunteer   donors.
Increasingly stringent donor- screening criteria have caused the donor pool, and
therefore the potential supply of blood, to contract. As a consequence, the cost
and intricacy of collecting,  testing and storing blood has greatly increased in
recent years,  and many blood banks have  experienced  inventory  shortages.  An
improved  synthetic  blood plasma volume expander that can be manufactured at an
economical  price would help  alleviate the blood  shortage  problems that arise
from dependence upon donated blood.

         Organ transplant surgery is a growing field. Approximately 5,000 donors
donate organs,  and  approximately  an additional 5,000 donors donate skin, bone
and other  tissues in the United  States each year. 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,  and  limits  preservation  times of those  organs for  transplant  use.
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.


The Products

Products for Surgery, Plasma Replacement and Emergency Care

         Background.  Severe blood loss during  surgery or from trauma  injuries
caused by blunt or

                                        4

<PAGE>



penetrating  force can  cause  fatal  shock.  Whole  blood or  packed  red cells
generally  cannot be  administered  to a patient until the patient's blood serum
has been  typed and  sufficient  units of  compatible  blood or red cells can be
located.  The use of human blood  products  also poses the risk of exposing  the
patient to blood borne  diseases  such as AIDS and  hepatitis.  While some fluid
needs  can  be  temporarily  met  by  various  colloid  and  crystalloid  plasma
extenders,  those solutions are generally not used to replace more than 30% of a
patient's blood. The solutions being developed by the Company are intended to be
more complete  synthetic  plasma volume expanders that can replace more than 30%
of a patient's blood volume and can provide more of the components  necessary to
prevent physiological shock during emergency care and surgical procedures.

         Synthetic Blood Plasma Expander. The Company is developing Hextend(R) ,
PentaLyteTM and other synthetic  plasma expander  solutions to treat acute blood
loss that occurs during many kinds of surgery,  particularly cardiac, orthopedic
and gastrointestinal  operations.  The solutions could also be used by emergency
room physicians or by paramedics  while the patient is being  transported to the
hospital  to  treat  acute  blood  loss in  trauma  victims.  Because  BioTime's
solutions are synthetic, they could be used without matching the patient's blood
type and would not pose the risk of transmitting AIDS,  hepatitis or other blood
borne infectious diseases.

         Hextend(R)  ,  PentaLyteTM  and  BioTime's   other  solutions   contain
constituents  that may prevent or reduce the  physiological  imbalances that can
impair or inhibit  blood  clotting  and  cardiac  function  in acute  blood loss
patients.  Hextend(R)  and  PentaLyteTM  are similar  formulations,  except that
Hextend(R) uses a high molecular weight hydroxyethyl starch (hetastarch) whereas
PentaLyteTM uses a low molecular weight hydroxyethyl starch  (pentastarch).  The
higher  molecular  hetastarch  is  retained  in the blood  longer than the lower
molecular  weight  pentastarch,  which may make Hextend(R) the product of choice
when a larger volume of plasma expander or blood  substitute for low temperature
surgery is needed or where the  patient's  ability to  regenerate  his own blood
after  surgery is  compromised.  PentaLyte,TM  with its lower  molecular  weight
pentastarch, would be eliminated from the blood faster than Hextend(R) and might
be used when less plasma expander is needed or where the patient is more capable
of quickly regenerating lost blood.

         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, so the lack of oxygen  carrying  molecules in the Company's
solutions should not pose a significant contraindication to use.

         Experiments by BioTime  scientists  have  demonstrated  that laboratory
animals  are able to survive at normal  temperatures  and  without  supplemental
oxygen when more than two-thirds of their  circulating  blood volume is replaced
by BioTime's  artificial  plasma  solution,  Hextend(R)  and  PentaLyteTM.  When
animals  are placed in an oxygen rich  environment,  they are able to survive at
normal temperatures when even more of their circulating blood volume is replaced
by Hextend(R).

         BioTime has a  cooperative  research  program  with the  Department  of
Surgery  at the  Metropolitan  Hospital  Center  in New  York  City to test  the
potential usefulness of Hextend(R) and

                                        5

<PAGE>



PentaLyteTM  as  trauma  care  products.   In  a  series  of  laboratory  animal
experiments,  researchers  at  Metropolitan  Hospital  have shown the ability of
Hextend(R) and PentaLyteTM to replace blood lost due to severe bleeding. Results
from certain of these tests indicate that  Hextend(R) and  PentaLyteTM may prove
more effective at maintaining  blood calcium levels than a leading  commercially
available  plasma extender when used to replace large volumes of blood.  Calcium
can be a significant  factor in regulating blood clotting and cardiac  function.
Results from other in vitro tests of Hextend(R)  indicate that  Hextend(R)  does
not alter the activity of a number of specific  blood  clotting  factors,  other
than by simple hemodilution.


Products for Hypothermic Surgery

         Background.  Approximately 400,000 coronary bypass and other open heart
surgeries are performed in the United States annually,  and approximately 18,000
aneurysm  surgeries  and  4,000  arterio-venous   malformation   surgeries  were
performed in the United States during 1989.  Those  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.

         CardioPulmonary  Bypass  Solution.  BioTime  plans  to test  the use of
Hextend(R) as  cardio-pulmonary  bypass circuit priming  solutions.  In order to
perform  heart  surgery,  the  patient's  heart must be stopped  and  mechanical
apparatus is used to oxygenate  and circulate  the blood.  The  cardio-pulmonary
bypass  apparatus  requires  a blood  compatible  fluid  such as  Hextend(R)  to
commence  and maintain the process of  diverting  the  patient's  blood from the
heart and lungs to the mechanical oxygenator and pump.

         BioTime  believes  that  Hextend(R)  will maintain  blood  pressure and
physiological balance better than the solutions presently used as bypass priming
solutions.  Approximately  1.5 to 2 liters of Hextend(R)  would be used for each
bypass operation. Based upon the number of coronary bypass operations performed,
the potential  market for Hextend(R) as bypass circuit priming  solutions in the
United States would be 600,000 to 800,000 liters annually.

                                        6

<PAGE>



         Low  Temperature  Blood  Substitute  Solution.   The  Company  is  also
developing Hextend(R) as a low temperature blood substitute that will be used to
replace  all of a  patient's  circulating  blood  volume to permit the rapid and
profound  cooling of  patients  in the  performance  of  surgery in  hypothermic
bloodless  conditions.  Although  surgeons are already using other  solutions to
supplement  the  blood  during  the  performance  of  certain  limited  surgical
procedures,  the  Company  is  not  aware  of  any  complete  blood-substitution
procedures in current surgical practice.

         Hextend(R)  would be  introduced  into the  patient's  body  during the
cooling  process.  Once the patient's body  temperature is near ice cold levels,
and the heart and brain are temporarily arrested,  the surgeon would perform the
operation.  During the surgery,  the solutions may be circulated  throughout the
body in place of blood,  or the  patient's  circulation  may be  arrested  for a
period of time if an interruption  of fluid  circulation is required in order to
perform the surgical  procedure.  Upon  completion  of the surgery,  the patient
would be slowly  warmed,  the  patient's  blood would be  reintroduced  into the
patient's vascular system and then warmed further.

         The Company  believes that low temperature  bloodless  surgery would be
primarily  suitable  for open  heart  operations,  operations  to  repair  major
vascular  disorders  such as  aneurysms,  and  removal of tumors from the brain,
head,  neck or heart.  Based upon  laboratory  studies  using  baboons and dogs,
BioTime  has  developed  protocols  for using  Hextend(R)  to replace all of the
subject's blood for one to four hours at temperatures  ranging from 10oC to 1oC.
BioTime has begun a series of laboratory studies testing the use of the solution
in low  temperature  open chest  cardiac  surgery in dogs.  The purpose of these
studies is to develop  protocols  for aortic  surgery and other  cardio-vascular
procedures in human patients.

         Minimally  Invasive  Cardiac  Surgery.  Cardiac surgeons are working to
develop  procedures to repair damaged  coronary  arteries and heart valves using
optically  guided  instruments that can be inserted into the heart through blood
vessels or small incisions, without the need to open the patient's chest cavity.
BioTime  believes  that  Hextend(R)  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 red blood.  BioTime intends to
conduct a series of laboratory studies using animal subjects to test the utility
of Hextend(R) as a low temperature blood substitute in such procedures.


Organ Transplant Products

         Background.  Organ transplant surgery is a growing field. Approximately
5,000 donors donate organs,  and approximately an additional 5,000 donors donate
skin,  bone and other  tissues in the United  States each year. 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.

         A  significant  problem  that arises  frequently  in the field of organ
transplant  surgery is the  inability to recover  more than a few viable  organs
from a donor. Currently, surgeons use different

                                        7

<PAGE>



preservation  solutions for different organs or different groups of organs. As a
result, a separate procedure using a different preservation solution is required
to preserve and remove each organ, or system of related  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.

         Another problem in the field of organ transplant  surgery is the timely
matching and delivery of compatible organs from donors to recipients. Currently,
an organ  available for  transplant is flushed with an ice cold 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 often fail to receive the
needed organs.

         Multi-Organ Preservation.  The Company is seeking to develop Hextend(R)
for use as a single  solution that can  simultaneously  preserve all of a single
donor's organs. When used as an organ preservation  solution,Hextend(R) 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 Hextend(R) 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 to 100 liters of Hextend(R).

         The Company believes that the ability to replace an animal's blood with
the Company's 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(R) as an organ preservative.

Other Potential Uses of BioTime Solutions

         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 may attempt to develop
products and  technologies  that can protect  tissues and organs from the damage
that  occurs when human  tissues  are  subjected  to  subfreezing  temperatures.
Proprietary  solutions and protocols  have already been developed by the Company
which allow  liquid  nitrogen  storage of full  thickness  rat and hamster  skin
grafts with subsequent survival following transplantation to host animals.

                                        8

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 disseminated,  inoperable tumors within vital organs. 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 June 30, 1996, the Company has spent $4,773,028
on research  and  development.  The greatest  portion of BioTime's  research and
development efforts have been devoted to the development of Hextend(R) and other
solutions for multi-organ  preservation,  low temperature surgery,  conventional
surgery and  emergency  care.  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.

         One 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  drugs  and
anesthetics,  the  temperatures  at which blood should be removed and  restored,
solution volume, the temperature range for maintaining  circulatory  arrest, and
the rate at which the subject should be rewarmed.

         Experiments  intended  to test  the  efficacy  of the  Company's  blood
substitute  solutions and protocols for surgical  applications involve replacing
the animal's blood with low temperature blood substitute  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,  using  both small and large
animals, at hospital and medical school 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 blood
substitute   solutions  with   commercially   available  FDA  approved  products
manufactured  by other  companies.  The  Company  intends to  continue to foster
relations  with  research  hospitals  and  medical  schools  for the  purpose of
conducting collaborative research projects because

                                        9

<PAGE>



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.

         It is the  Company's  policy  to retain  all  patent  and  intellectual
property rights to its products,  including any improvements that may be derived
or refined from Company financed research programs.  However,  to obtain funding
for additional  research and development for pre-clinical and clinical  studies,
the  Company  may  seek  to  enter  into  joint  venture,  licensing,  or  other
collaborative  arrangements with pharmaceutical companies. There is no assurance
that any such arrangements can be made.


Manufacturing

Facilities Required

         The Company has  sufficient  equipment,  space and personnel  needed to
synthesize the quantities of Hextend(R) used in its research  activity,  but the
Company does not have  facilities  to  manufacture  the  solution in  commercial
quantities,  or under "good  manufacturing  practice"  required by the FDA.  Any
products that are approved by the FDA will have to be manufactured  according to
"good  manufacturing  practices" in commercial  quantities,  and with sufficient
stability to withstand the  distribution  process,  and in compliance  with such
federal  and state  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". In order to obtain FDA
approval for the sale of its  synthetic  blood  plasma  volume  expander,  blood
substitute  and organ  preservation  solutions,  the Company will be required to
conduct   clinical  trials  using  products   manufactured   according  to  good
manufacturing   practices,  at  a  facility  that  has  passed  FDA  inspection.
Accordingly,   the  Company  will  need  to  enter  into  product  manufacturing
arrangements with an established pharmaceutical company or the Company will have
to acquire its own manufacturing facility.

         Through  an  agreement   with  McGaw,   Inc.,  a  subsidiary   of  IVAX
Corporation,  BioTime has obtained  approximately 6,000 liters of Hextend(R) for
use in human  clinical  trials and in  stability,  pharmacology  and  toxicology
testing.   Discussions  are  continuing  with  McGaw  and  other  pharmaceutical
companies  regarding the  commercial  manufacture  and marketing of  Hextend,(R)
PentaLyteTM and other BioTime blood plasma volume expander and blood replacement
products.

         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. To avoid the incurrence
of those  expenses  and delays,  the Company is seeking  contract,  licensing or
joint venture  arrangements  with established  pharmaceutical  companies for the
production  of  the  Company's   products.   In  joint   ventures  or  licensing
arrangements  that include marketing  rights,  the participating  pharmaceutical
company  would be entitled to a large  portion of the profits  from sales to end
users or would pay the Company a royalty on net sales.

                                       10

<PAGE>



         If  contractual  arrangements  for  the  manufacture  of the  Company's
products cannot be made on terms acceptable to the Company, the Company would be
required to establish its own  production  facilities.  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.
There can be no  assurance  that the Company  will be able to obtain the capital
required for the  acquisition  of production  facilities,  or that  satisfactory
arrangements  will be made with third parties to manufacture  and distribute any
products.


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  active
ingredient in  Hextend(R)  and  PentaLyte(TM).  One of the  hydroxyethyl  starch
manufacturers  is  McGaw,   Inc.,  which  has  produced  limited  quantities  of
Hextend(R) for BioTime's use in clinical trials.

         BioTime  is  pursuing  discussions  with  McGaw and other  hydroxyethyl
starch  manufacturers to obtain commercial  quantities of hydroxyethyl starch or
Hextend(R) and PentaLyte.(TM)  However,  McGaw and other  manufacturers  produce
hydroxyethyl  starch  for use in plasma  expanders  with  which  Hextend(R)  and
PentaLyte(TM)  might  compete  and  there  is no  assurance  that  any of  those
manufacturers  will be willing to provide  hydroxyethyl  starch to BioTime or to
manufacture  and market  Hextend,(R)  PentaLyte(TM)  or other  products  under a
license from BioTime.

         If the  Company  is unable to secure a supply or  production  agreement
with one of the  known  manufacturers,  the  Company  would  have to  acquire  a
manufacturing  facility  and  the  technology  to  produce  hydroxyethyl  starch
according  to "good  manufacturing  practices."  The  possibility  of  producing
hydroxyethyl  starch  through a  co-operative  effort with a small,  independent
starch  manufacturer is also being  considered.  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, BioTime 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,
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 by
BioTime, would be as safe or effective in BioTime's solutions.

Marketing

         The Company has not established a marketing and sales organization, but
it may need to do so if it obtains FDA approval for commercial production of its
products.  The Company's proposed products and services are intended for sale to
hospitals,  medical  centers and scientists  engaged in the practice of specific
areas of medicine or medical research, including transplantation,  neurosurgery,
cardiovascular  surgery,  anesthesiology,  oncology,  emergency  room and trauma
care, critical care, and biomedical research.

         The  Company  intends  to seek  contract,  licensing  or joint  venture
arrangements  with  established   pharmaceutical  companies  for  marketing  the
Company's  products.  Although  such  arrangements  could  permit the Company to
receive  revenues  from the sale of its  products  expeditiously  and with lower
costs,  the Company would have to share those  revenues  with the  participating
pharmaceutical  companies.  There can be no  assurance  that any  pharmaceutical
companies  will be  willing  to  enter  into  marketing  arrangements  on  terms
acceptable to the Company.

         If the Company does not enter into licensing or other  arrangements for
the sale of its products by one or more  pharmaceutical  companies,  the Company
would have to establish its own marketing organization. Due to the complexity of
the technologies being developed by the Company, prospective end-users will have
to be trained in the proper use of products that the Company may develop.

         In order to market any new  products it may  develop,  the Company also
plans to publish studies in scientific journals,  and to present studies and the
results  of  its  work  at  meetings  of  medical  and  scientific  professional
organizations.  BioTime  also will  continue  to seek  opportunities  to conduct
research in  collaboration  with well-known  institutions and to demonstrate its
work at scientific conventions.


Government Regulation

         The FDA  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.  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 but will also be reviewed by the FDA staff
responsible for evaluating biologicals.

         The  Company's  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 hopital 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

                                       12

<PAGE>



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 also  regulates  the  manufacturing  process of  pharmaceutical
products and requires that a portion of the clinical  trials for new products be
conducted  using  products  produced  in  compliance  with  "good  manufacturing
practices." See "Manufacturing."

         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 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

         On April 18, 1995, the Company was granted a United States Patent which
protects methods for using BioTime's proprietary solutions, including the use of
Hextend(R)  and  PentaLyteTM  to replace  blood.  Claims  include the use of the
solutions at normal and hypothermic  (below normal) body  temperatures as plasma
expanders,  and for increasing  circulation of a hypovolemic  (acute blood loss)
patient. Additional patent applications have been filed in the United States and
certain  other  countries  for  Hextend(R)  and other  solutions.  These  patent
applications  include  claims for patent  protection of the  composition  of the
Company's solutions and patent protection of methods of using the solutions. The
Company also holds a United States Patent on its microcannula.

         The Company has been informed  that 62 additional  claims in two patent
applications  have been  allowed;  and patents are  expected to issue within the
next six months.  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
the  prosecution  of  litigation  against  third  party  infringers,   and  such
litigation can be costly to pursue.

         While the Company  believes that the protection of patents and licenses
is  important  to its  business,  the Company  also 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

                                       13

<PAGE>



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.  If,  in the  future,  the  techniques  for  use of the
Company's   products  become  widely  known  through  academic   instruction  or
publication,  patent  protection  would  become  more  important  as a means  of
protecting the Company's market share for its products.



Licensed Products and Technology

         The Company has obtained from  Cryomedical  Sciences,  Inc.  ("CMSI") a
royalty free,  non-exclusive  license to make,  have made,  use and sell certain
experimental  hypothermic  blood substitute  solutions for cryonics,  cancer and
AIDS research and treatment.  The licensed  solutions were developed by three of
BioTime's  scientists  while  they were  employed  by CMSI  before  BioTime  was
founded.  The license  granted by CMSI will  terminate  if Paul  Segall,  Harold
Waitz,  Hal Sternberg,  Judith Segall,  Lawrence  Cohen,  Donna Cohen,  Victoria
Bellport,  Alan  Gelband,  Trans Time,  Inc.  (a  corporation  in which  certain
officers  and  directors of BioTime own an  interest)  and Ronald  Barkin in the
aggregate do not own at least 33-1/3% of the  Company's  Common Shares which are
not sold to the public or otherwise owned by public shareholders (the "Insiders'
Shares").  As of June 30,  1996,  such  persons  owned an  aggregate  of 596,165
shares,  representing 98% of the Insiders' Shares. The license is not assignable
or transferable.

         The  technology  and  solutions  licensed  from  CMSI  were used by the
Company's  scientists  in its  initial  experiments.  However,  the  Company has
developed its own patented blood  substitute and organ  preservation  solutions,
and is no longer using CMSI's solutions in its research and development  program
and does not  intend to pursue the  commercial  exploitation  of those  licensed
solutions.


Competition

         If successfully  developed,  the Company's  solutions will compete with
the  plasma  volume  expanders  and  organ  preservation   solutions   presently
manufactured  by  established  pharmaceutical  companies,  and with human  blood
products. For example,  DuPont  Pharmaceuticals  presently markets Hespan,(R) an
artificial  plasma volume  expander,  and Viaspan,(TM) a solution for use in the
preservation of kidneys,  livers and pancreases for surgical  transplant.  Other
blood plasma replacement products are being developed,  and clinical trials have
either  begun or are  expected  to begin  in the near  future  for some of these
products,  including  Pentaspan(TM)  (a solution used for the  collection of red
blood cells from  patients)  and a  genetically  engineered  human  albumin.  To
compete  with new and  existing  plasma  expanders,  the  Company is  developing
products that contain  constituents that may prevent or reduce the physiological
imbalances that can affect the patient's  tissue and organ function.  To compete
with existing organ preservation solutions,  the Company is seeking to develop a
solution  that can be used to preserve  all organs  simultaneously  and for long
periods of time.

         CMSI, which was founded by four of the Company's executive officers and
directors,  is  attempting  to develop blood  substitution  and cold  protecting
solutions for low temperature surgery,

                                       14

<PAGE>



for organ preservation and for the treatment of trauma victims.  Somatogen, Inc.
is  developing  a  synthetic  hemoglobin  blood  substitute  that may also  have
application in bloodless surgery,  in treatment of trauma victims,  and in organ
preservation.  A number of other companies are known to be developing artificial
hemoglobin and other synthetic red blood cell substitutes and technologies  that
may compete  directly  with the  products and  technologies  that the Company is
developing.  In general,  red cell substitutes are more expensive to produce and
potentially more toxic than Hextend(R) and PentaLyte.TM  Some of these competing
companies have substantially larger research facilities and technical staffs and
greater financial and marketing resources than BioTime.

         Generic  plasma  expanders  intended  to  compete  with  HespanTM  have
recently been introduced in the United States market.  As a result,  competition
in the  plasma  expander  market  has  intensified  and  wholesale  prices  have
declined. Competition in the areas of business targeted by the Company is likely
to intensify 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 June 30, 1996,  the Company  employed nine persons on a full-time
basis and two persons on a part-time  basis.  Three of the  full-time  employees
hold Ph.D. or Masters Degrees in one or more fields of science.


Item 2. Facilities

         The Company  presently  occupies  an  approximately  5,200  square foot
office and laboratory  facility in Berkeley,  California under a lease that will
expire on May 31, 1997,  subject to the Company's  option to renew the lease for
an  additional  24 month  period.  The current rent is $5,000 per month.  If the
Company  exercises  its renewal  option,  rent during the option  period will be
$5,300  per  month,  plus the cost of  utilities.  This  facility  serves as the
Company's   principal   executive   office  and   laboratory  for  small  animal
experiments.

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

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.  The  Company has not yet
generated  significant  operating revenues,  and as of June 30, 1996 the Company
had incurred a cumulative net loss of $8,064,471.

         Most of the  Company's  research  and  development  efforts  have  been
devoted to the development of Hextend(R) and  PentaLyte.TM The Company has filed
an IND with the FDA and has received  permission to commence  Phase III clinical
trials of Hextend(R) in human  patients.  These clinical  trials are expected to
begin in October 1996 at the Duke  University  Medical  Center in Durham,  North
Carolina.  Additional  studies  are  being  designed  to  assess  the  value  of
Hextend(R) in other surgical applications. The costs of such clinical trials and
other studies may be  substantial,  and it might be necessary for the Company to
obtain additional financing in order to complete these studies.

         In order to bring  other  new  products,  such as  Pentalyte,TM  to the
medical  market place,  it will be necessary for the Company to file an IND with
the FDA  and to  conduct  clinical  trials  of each  new  product.  The  cost of
preparing  those  IND  filings  and  conducting  those  clinical  trials  is not
presently determinable. It may be necessary for the Company to obtain additional
financing in order to complete  any  clinical  trials that may begin for its new
products.

         The Company  plans to continue  to provide  funding for its  laboratory
testing  programs at selected  medical  schools and hospitals for the purpose of
developing  additional  uses of Hextend,(R)  PentaLyteTM and other new products,
but the amount of research  that will be  conducted at those  institutions  will
depend  upon the extent to which the Company  can raise  sufficient  capital for
research in addition to the funding  required  for the  clinical  testing of new
products. If funding for collaborative research at medical schools and hospitals
is curtailed,  the Company will have to rely on in-house  research,  using small
laboratory animals and less sophisticated surgical procedures.

         To  address  its  anticipated  need  for  manufacturing  and  marketing
resources,  the Company is  continuing  to identify  domestic and  international
pharmaceutical  companies  that,  based upon  their  current  product  lines and
resources, might be able to manufacture and market the Company's products if and
when the necessary  regulatory  approvals are obtained.  The  acquisition of the
Company's own  production  facilities  and the  development of the Company's own
marketing organization is also being considered in the event that production and
marketing arrangements cannot be made with established  pharmaceutical companies
on  terms  that the  Company  deems  advantageous.  Additional  capital  will be
required in order for the Company to acquire its own  production  facilities and
marketing organization.

         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 losses from operations
will continue to be incurred for the foreseeable future.

Results of Operations

Years Ended June 30, 1996 and June 30, 1995

         From  inception  (November 30, 1990) through June 30, 1996, the Company
generated  $729,332 of revenues,  comprised of $50,634 from the sale of products
and services,  and $678,698 in interest.  For the year ended June 30, 1996,  the
Company  generated  $130,882  of  revenues,  including  $3,670  from the sale of
products,  and  $127,212  in  interest.  For the year ended June 30,  1995,  the
Company generated total revenues of $222,383,  comprised of $3,967 from the sale
of microcannulas and solutions for research purposes,  and $218,416 in interest.
The decrease in interest income is attributable to the decrease in cash and cash
equivalents  from  1995  to  1996.  Limited  test  marketing  of  the  Company's
laboratory research equipment, through advertisements in trade publications, has
resulted in sales of a small number of  microcannulas.  Although the Company may
continue to test market its laboratory  research  equipment,  and to promote its
ability  to  perform  research  services,  the  Company's  ability  to  generate
substantial  operating  revenue  depends  upon its  success  in  developing  and
marketing its blood substitute and organ  preservation  solutions and technology
for medical use.

         From  inception  (November 30, 1990) through June 30, 1996, the Company
incurred  $4,773,028 of research and development  expenses,  including salaries,
supplies and other expense items. Research and development expenses decreased to
$1,142,168 for the year ended June 30, 1996,  from $1,791,698 for the year ended
June 30, 1995. The decrease in research and development expenses is attributable
to a decrease in the number and scope of research  collaborations the Company is
sponsoring,  since  there  has been a shift in the  focus  of the  Company  from
research to clinical  studies.  It is expected  that  research  and  development
expenses will increase as the Company commences clinical testing of Hextend(R).

         From  inception  (November 30, 1990) through June 30, 1996, the Company
incurred  $4,020,775  of  general  and  administrative  expenses.   General  and
administrative  expenses increased to $954,049 for the year ended June 30, 1996,
from  $808,432  for the year ended June 30,  1995.  This  increase is  primarily
attributable  to an  amortized  expense of $143,000  associated  with a two year
agreement  the Company  entered  into with a financial  advisor in exchange  for
warrants to purchase the Company's common shares (See Note 5 to the accompanying
financial statements). Otherwise, general and administrative expenses decreased,
due to a general  concentration  of resources and personnel on  development  and
testing of the Company's products.


Years Ended June 30, 1995 and June 30, 1994

         For the year ended June 30, 1995, the Company  generated total revenues
of $222,383,  comprised of $3,967 from the sale of  microcannulas  and solutions
for research  purposes,  and  $218,416 in interest.  For the year ended June 30,
1994, the Company had total revenues of

                                       20

<PAGE>



$162,154,  comprised  of $9,716  from the sale of  products  and  services,  and
$152,438 in interest.  During March 1994, the Company  completed a second public
offering of its common  shares.  The increase in interest  income in fiscal year
1995 over  fiscal  year 1994 is  attributable  to the  increase in cash from the
public offering and investment of the offering proceeds.

         Research and development  expenses increased to $1,791,698 for the year
ended  June 30,  1995,  from  $777,668  for the year ended  June 30,  1994.  The
increase in research and development  expenses is attributable to an increase in
the scope of Company sponsored research collaborations, the manufacturing of two
lots of  Hextend(R)  solution  under  "good  manufacturing  practices,"  and the
initiation of stability,  toxicology and pharmacology  studies needed for filing
of the Company's first Investigational New Drug application (IND).

         General and administrative  expenses decreased to $808,432 for the year
ended June 30, 1995 from $931,439 for the year ended June 30, 1994. The decrease
in general and  administrative  expenses is due largely to a focus of  resources
and personnel to development and testing of the Company's products.


Taxes

         At June 30,  1996,  the Company had a  cumulative  net  operating  loss
carryforward of approximately $7,866,000 for federal income tax purposes.


Liquidity and Capital Resources

         Because of the developmental  nature of the Company's  business,  it is
unlikely that in the near future the Company will be able to generate internally
the funds necessary to carry on its planned operations. The Company expects that
its cash on hand will be sufficient to finance the Company's  operations for the
next 12 months. Since inception, the Company has financed its operations through
the sale of equity securities.  Presently, the Company is seeking financing from
pharmaceutical  and medical device companies that may be interested in licensing
or  otherwise  acquiring  marketing  rights  to  Hextend(R)  and  other  BioTime
products.  Financing may also be obtained through  additional  public or private
offerings of equity and debt securities.

         The future  availability  and terms of equity and debt  financings  and
collaborative  arrangements  with industry  partners  cannot be  predicted.  The
unavailability  or  inadequacy  of financing to meet future  capital needs could
force the Company to modify,  curtail,  delay or suspend  some or all aspects of
its planned operations.

Board of Directors and Shareholders
BioTime, Inc.


We have audited the accompanying balance sheets of BioTime,  Inc. (a development
stage  company) as of June 30,  1996 and 1995,  and the  related  statements  of
operations,  shareholders'  equity,  and cash flows for the period from November
30,  1990  (inception)  to June 30,  1996 and for each of the three years in the

standards.  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 June 30, 1996 and 1995,
and the  results  of its  operations  and its cash  flows  for the  period  from

                                           NOTES TO FINANCIAL STATEMENTS

1.       GENERAL AND DEVELOPMENT STAGE ENTERPRISE

         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 research and
         development of synthetic plasma expanders,  blood 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  blood  substitute  and  organ  preservation
         products.  The Company has not had any significant  operating  revenues
         and has incurred  operating losses of $8,064,471 from inception to June
         30,  1996.   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 products that may be ultimately developed and achieving a
         level of sales adequate to support the Company's cost structure.

         While the Company  successfully  completed two public  offerings of its
         common  shares  and,  at June 30,  1996,  had  remaining  cash and cash
         equivalents of over  $2,400,000,  management  believes that  additional
         funds will be required  for the  successful  completion  of its product
         development activities.


2.       SIGNIFICANT ACCOUNTING POLICIES

         Cash and cash  equivalents  include cash,  money market funds, and U.S.
         Government securities with original maturities of three months or less.

         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 sixty months.

         Organizational costs are amortized over a period of sixty months.

         Patent  costs  associated  with  obtaining  patents on  products  being
         developed  are  expensed  as research  and  development  expenses  when
         incurred. These costs totaled $95,598 for the year ended June 30, 1996,
         $83,430  for the year ended June 30,  1995,  $60,777 for the year ended
         June 30, 1994, and cumulatively, $276,617 for the period from inception
         (November 30, 1990) to June 30, 1996.

         Research and development supplies on hand are comprised of a quantity

                                       30

<PAGE>



         of the Company's Hextend(R) solution for use in human clinical trials.

         Research and  development  costs,  consisting  principally of salaries,
         payroll taxes, research and laboratory fees, are expensed as incurred.

         Income  Taxes:  At June 30,  1996,  the  Company has not  realized  any
         taxable  income  since its  inception  and has  federal  and state loss
         carryforwards of $7,866,000 and $3,933,000 for both financial statement
         and tax purposes as follows:

         Year of
         Expiration                         Federal            State
         ----------                         -------            -----
           2006                            $  255,000       $ 128,000
           2007                               710,000         355,000
           2008                             1,209,000         604,000
           2009                             1,547,000         774,000
           2010                             2,348,000       1,174,000
           2011                             1,797,000         898,000

           Total                           $7,866,000      $3,933,000

         In the event of a  significant  change in the ownership of the Company,
         the  utilization  of such  loss  carryforwards  could be  substantially
         limited.

         Net Loss Per Share is based on the  weighted  average  number of common
         shares  outstanding  during  the  periods  presented.  For all  periods
         presented,  all  unexercised  warrants and options are considered to be
         antidilutive and were not included in the computation.


3.       COMMITMENTS AND CONTINGENCIES

         The Company has employment  agreements with five  officers/shareholders
         for the  five-year  period  commencing  June 1, 1996 that  provide  for
         compensation for each individual at $85,000 for the first year, $92,000
         for the second  year,  $99,000  for the third  year,  $106,000  for the
         fourth   year,    and    $113,000    for   the   fifth   year.    These
         officers/shareholders have signed intellectual property agreements with
         the Company as a condition of their employment.

         The Company had an employment agreement with the former Chairman of the
         Board/shareholder  for the three year period  commencing April 25, 1994
         that provides for compensation at $60,000 for the first year,  $100,000
         for the second year,  and $105,000 for the third year. The Chairman has
         signed  an  intellectual  property  agreement  with  the  Company  as a
         condition of his employment.

         In December  1990,  the Company was granted a fully paid,  royalty-free
         worldwide irrevocable  nonexclusive license to make, have made, use and
         sell CMSI's hypothermic blood substitute solution that exists in CMSI's
         patent application. The license granted by CMSI will terminate

         if certain  officers/shareholders  in the aggregate do not own at least
         33 1/3% of the  interest  in the  Company  not  sold to the  public  or
         otherwise owned by public shareholders. At June 30, 1996 the license is
         still in effect.


4.       LEASES

         In June 1993, the Company  entered into a two-year lease  agreement for
         its  principal  office and research  facilities.  Rent expense  totaled
         $58,188,  $53,388,  and  $25,200 for each of the three years ended June
         30, 1996, 1995 and 1994, respectively; and cummulatively,  $167,326 for
         the period from inception to June 30, 1996. During July 1994, the lease
         was amended to include  additional  space and to extend the  expiration
         period to May 31, 1997,  subject to the  Company's  option to renew the
         lease for an additional  24 month period.  Rent for the initial term of
         the new lease is $4,500 per month for the first year,  $4,900 per month
         for the second  year,  and $5,000 per month for the third year.  If the
         Company exercises its option to renew the lease, rent during the option
         period will be $5,300 per month, plus the cost of utilities.

5.       SHAREHOLDERS' EQUITY

         In May 1991, the Company  received  $121,763,  net of offering costs of
         $6,237, in a private  placement  offering in exchange for 71,117 common
         shares.  The investors in certain states where the shares were sold may
         have had the  right to  rescind  their  investment  in  37,392  shares.
         Accordingly,  37,392  shares and related  amounts  were  excluded  from
         shareholders' equity in the financial statements.  As of June 30, 1996,
         any such right to rescind the investment had lapsed,  and 37,392 shares
         have been included in shareholders' equity in the financial statements.

         In March 1992,  the Company  completed an  underwritten  initial public
         offering of 724,500 common shares, at an initial price to the public of
         $8.00 per share.  The net  proceeds  to the  Company,  after  deducting
         expenses of the offering, was $4,780,127.

         Under the terms of the underwriting  agreement for the public offering,
         the  Company  sold to the  underwriter,  for $60,  warrants to purchase
         61,889 common shares at an exercise  price of $9.60 per share,  subject
         to  adjustment to prevent  dilution.  The  underwriter's  warrants will
         expire on March 4,  1997.  As a result of  dilution,  adjustments  were
         made;  and some  warrants  have been  exercised.  Warrants  to purchase
         36,563  common  shares  at an  exercise  price of $7.81,  as  adjusted,
         remained outstanding at June 30, 1996.

         In March 1994,  the  Company  completed  a second  underwritten  public
         offering of 935,200 common shares, at an initial price to the public of
         $5.125 per share.  The net  proceeds to the  Company,  after  deducting
         expenses  of the  offering,  was  $3,927,074.  Under  the  terms of the
         underwriting agreement for the public offering, the Company sold to the
         underwriter,  for $5,  warrants to purchase  90,000 common shares at an
         exercise  price of $7.18 per share,  subject to  adjustment  to prevent
         dilution.  These  underwriter's  warrants will expire on March 4, 2000.
         Some  warrants have been  exercised  and at June 30, 1996,  warrants to
         purchase 81,000 common shares remained outstanding.

         The Board of  Directors  of the Company  adopted the 1992 Stock  Option
         Plan  (the  "Plan")  in  September  1992,  which  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  400,000
         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.

         At June 30, 1996,  options for the purchase of 230,000 shares under the
         Plan  were  held by  employees,  officers,  directors,  members  of the
         scientific  advisory  board and certain  consultants.  Such options are
         exercisable at prices  ranging from $1.99 to $10.79  beginning from one
         to two years  after the grant date and  expire  after five to ten years
         from the  grant  date.  Certain  options  require  the  achievement  of
         performance   criteria.   At  June  30,  1996,   167,498  options  were
         exercisable at prices ranging from $1.99 to $10.79.  Options for 57,000
         common  shares have been  exercised as of June 30, 1996.  During fiscal
         1996, 62,000 options were granted.

         During 1996, certain consultants agreed to accept stock options as full
         or partial payment for the services they render to the Company. Options
         to purchase a total of 60,000 shares were issued to those  consultants.
         The fair value of the  consulting  services is the basis for  recording
         the  transaction  in  the  Company's  financial  records  and  will  be
         recognized  as the related  services are  performed  ($25,000 in fiscal
         1996).

         During  September  1995,  the Company  entered into an agreement with a
         firm  to  act as its  financial  advisor.  In  exchange  for  financial
         consulting services associated in part with a plan to secure additional
         capital,  the  Company  issued to the  financial  advisor  warrants  to
         purchase  100,000  common  shares at a price of $6 per  share,  and the
         Company  agreed  to issue  additional  warrants  to  purchase  up to an
         additional 200,000 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 grant or (b) $6 per share. The additional warrants were
         to be issued in equal  quarterly  installments  over a two year period,
         beginning  October 15, 1995.  The Company may  terminate  the financial
         advisory  agreement on 30 days  notice,  in which case the next warrant
         issuance   would  be  accelerated  to  the  date  on  which  notice  of
         termination is given, but no additional warrants would be issued. As of
         June 30, 1996,  the total number of warrants to purchase  Common Shares
         issued was 175,000;  150,000 of which will be exercisable at a price of
         $6 per share,  and 25,000 of which  will be  exercisable  at a price of
         $7.32  per  share.  As of  July  15,  1996,  warrants  to  purchase  an
         additional  25,000 shares were issued,  which will be  exercisable at a
         price of $30.04 per share.

         The total value of these  warrants at the agreement  date was estimated
         to be approximately  $300,000.  The financial advisor was assisting the
         Company in identifying  and  negotiating  with potential  investors and
         investment  bankers.  It was the  Company's  expectation  to complete a
         financing  by the first  quarter  of fiscal  1997 and to  include  this
         amount in expenses of the offering.  During the fourth quarter of 1996,
         the Company  determined  that the financing  would not occur within its
         initial timing estimate and  accordingly  capitalized the warrant value
         and is amortizing this amount over the term of the agreement.

         In October 1995, the Financial  Accounting  Standards Board issued SFAS
         No. 123,  "Accounting for Stock-Based  Compensation," which the Company
         will adopt in fiscal year 1997. Pursuant to the new standard, companies
         are encouraged, but are not required, to adopt the fair value method of
         accounting for employee  stock-based  transactions.  Companies are also
         permitted to continue to account for such transactions under Accounting
         Principles  Board  Opinion  No.  25,  "Accounting  for Stock  Issued to
         Employees,"  but would be  required to  disclose  pro forma  results of
         operations in a note to the financial statements and, if presented, per
         share  amounts  as if  the  company  had  applied  the  new  method  of
         accounting.  The  Company  has not yet  determined  if it will elect to
         change to the fair value method,  nor has it determined  the effect the
         new  standard  will have on  operating  results  and  related per share
         amounts  should  it  elect to make  such  change.  Adoption  of the new
         standard will have no effect on the Company's cash flows.

         In  June  1994,  the  Board  of  Directors  authorized   management  to
         repurchase  up to  200,000  shares of the  Company's  common  shares at
         market  price at the time of  purchase.  As of June  30,  1996,  90,800
         shares have been repurchased and retired.

6.       RELATED PARTY TRANSACTIONS

         During the years ended June 30, 1994, 1995 and 1996,  $9,230,  $81,043,
         and   $19,940  in  fees  for   consulting   services   was  paid  to  a
         shareholder/member of the Board of Directors.

Compliance with Section 16(a) of the Securities Act of 1934

         Section 16(a) of the  Securities  Exchange Act of 1934, as amended (the
"Exchange  Act"),  requires the Company's  directors and executive  officers and
persons  who own  more  than ten  percent  (10%)  of a  registered  class of the
Company's equity securities to file with the Securities and Exchange  Commission
(the "SEC") initial  reports of ownership and reports of changes in ownership of
Common Shares and other equity  securities of the Company.  Officers,  directors
and greater than ten percent beneficial owners are required by SEC regulation to
furnish the Company with copies of all reports they file under Section 16(a).

         To the Company's knowledge, based solely on its review of the copies of
such reports furnished to the Company and written  representations that no other
reports were required,  all Section 16(a) filing requirements  applicable to its
officers, directors and greater than ten percent beneficial owners were complied
with during the fiscal year ended June 30, 1996.


Item 11.   Executive Compensation.

         None of the Company's executive officers received compensation from the
Company in excess of $100,000  during the fiscal year ended June 30,  1996.  The
Company has entered into a new five-year  employment  agreement (the "Employment
Agreement") with Paul Segall,  the President and Chief Executive  Officer of the
Company.  The  Employment  Agreement  will expire on  December  31, 2000 but may
terminate  prior to the end of the term if Dr.  Segall (1) dies,  (2) leaves the
Company,  (3) becomes disabled for a period of 90 days in any 150 day period, or
(4) is  discharged  by the  Board of  Directors  for  failure  to carry  out the
reasonable policies of the Board, persistent  absenteeism,  or a material breach
of a covenant. Under his Employment Agreement, Dr. Segall is presently receiving

Item 13.   Certain Relationships and Related Transactions.

         During  the twelve  months  ended  June 30,  1996,  $19,940 in fees for
consulting  services  was paid to  Ronald  S.  Barkin,  a member of the Board of
Directors.

         During  September  1995,  the Company  entered  into an  agreement  for
financial  advisory  services with Greenbelt Corp., a corporation  controlled by
Alfred D.  Kingsley and Gary K.  Duberstein.  Under this  agreement  the Company
issued to the financial  advisor warrants to purchase 100,000 common shares at a
price of $6 per share,  and the Company agreed to issue  additional  warrants to
purchase  up to an  additional  200,000  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) $6 per share.  The  additional  warrants
were to be  issued  in equal  quarterly  installments  over a two  year  period,
beginning  October 15, 1995.  The Company may terminate  the financial  advisory
agreement on 30 days notice,  in which case the next warrant  issuance  would be
accelerated  to the  date on  which  notice  of  termination  is  given,  but no
additional  warrants  would be issued.  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. As of
June 30, 1996, the total number of warrants to purchase common shares issued was
175,000;  150,000 of which will be exercisable  at a price of $6 per share,  and
25,000 of which will be  exercisable  at a price of $7.32 per share.  As of July
15, 1996,  warrants to purchase an additional  25,000 shares were issued,  which
will be exercisable at a price of $30.04 per share.

         Under the agreement,  upon the request of Greenbelt  Corp., the Company
will file a  registration  statement to register  the  warrants  and  underlying
Common Shares for sale under the  Securities Act of 1933, as amended (the "Act")
and  applicable  state  securities or "Blue Sky" laws. The Company will bear the
expenses of  registration,  other than any  underwriting  discounts  that may be
incurred by Greenbelt  Corp. in connection with a sale of the warrants or common
shares.  The  Company  shall  not be  obligated  to  file  more  than  two  such
registration  statements,  other  than  registration  statements  on  Form  S-3.
Greenbelt  Corp.  also is entitled to include  warrants and common shares in any
registration  statement  filed by the Company to register  other  securities for
sale under the Act.

         The Company has agreed to reimburse  Greenbelt Corp. for all reasonable
out-of-pocket  expenses  incurred in connection with its engagement as financial
advisor,  and  to  indemnify  Greenbelt  Corp.  and  the  officers,  affiliates,
employees, agents, assignees, and controlling person of Greenbelt Corp. from any
liabilities  arising out of or in connection with actions taken on behalf of the
Company under the agreement.

                              EMPLOYMENT AGREEMENT


         THIS AGREEMENT is made June 1, 1996, by and between BioTime,  Inc. (the
"Company"), and Paul E. Segall, Ph.D. (the "Employee").

                              W I T N E S S E T H:

         WHEREAS,  the  Company  desires to employ  Employee,  and  Employee  is
willing  to  accept  such  employment,  all  on the  terms  and  subject  to the
conditions hereinafter set forth;

         NOW,   THEREFORE,   in   consideration  of  the  terms  and  conditions
hereinafter set forth, the parties hereto agree as follows:


         1. Employment. The Company hereby employs Employee, and Employee hereby
accepts  employment  with the  Company  on the terms and  conditions  herein set
forth.

         2. Term of Agreement. This Agreement shall commence on June 1, 1996 and
shall continue in effect until December 31, 2000 (the "Expiration Date"), unless
terminated pursuant to the express provisions of this Agreement.

         3.  Renewal.  This  Agreement  shall be  renewed  automatically  for an
additional  one (1) year  period  on  January  1,  2001 and on each  anniversary
thereof,  unless one party gives the other advance written notice of non-renewal
at least sixty (60) days prior to such date. Either party may elect not to renew
this Agreement with or without cause.

         4.  Position;  Duties.  Employee  shall be employed in the position and
shall  perform  the  duties  and  functions  set  forth on  EXHIBIT  A, and such
additional duties and functions as are normally carried out by an executive in a
comparable position with a developer of pharmaceutical or medical products,  and
as the Board of Directors or a duly authorized officer of the Company shall from
time to  time  reasonably  determine.  Employee  shall  devote  his or her  best
efforts,  skills  and  abilities,  on a  full-time  basis,  exclusively  to  the
Company's  business  pursuant to, and in accordance  with,  reasonable  business
policies and procedures, as fixed from time to time by the Board of Directors of
the Company (the "Board of Directors"). Employee covenants and agrees that he or
she will faithfully  adhere to and fulfill such policies as are established from
time to time by the Board of Directors.

         5. Compensation

                  5.1 Salary and Bonuses. During the term of this Agreement, the
Company shall pay to the Employee:

                         5.1.1 Base  Salary.  A base  annual  salary  (the "Base
Salary") in the following amounts: Eighty-Five Thousand Dollars ($85,000) during
the calendar year beginning

                                        1

<PAGE>



January 1, 1996;  Ninety-Two Thousand Dollars ($92,000) during the calendar year
beginning  January 1, 1997;  Ninety-Nine  Thousand Dollars  ($99,000) during the
calendar  year  beginning  January 1, 1998;  One  Hundred Six  Thousand  Dollars
($106,000)  during the calendar year beginning  January 1, 1999; and One Hundred
Thirteen Thousand Dollars  ($113,000) during the calendar year beginning January

in such other  installments as may be agreed upon between the parties.  The Base
Salary  may be  increased  from time to time in the  discretion  of the Board of
Directors.

                         5.1.2  Financing   Bonus.   Employee  shall  receive  a
one-time cash bonus in the amount of Twenty-Five  Thousand Dollars  ($25,000) if
the  Company  receives  at least  One  Million  Dollars  ($1,000,000)  of equity
financing from a pharmaceutical  company. Such bonus shall be paid within thirty
(30) days after the Company has  received  such  $1,000,000.  For the purpose of
this paragraph the following  provisions shall apply: (a) all payments made by a
pharmaceutical company on an installment basis, or upon the exercise of options,
warrants or other rights will be aggregated; and (b) in the event of an exchange
or conversion of any debt security or evidence of  indebtedness  for or into any
equity  security of the  Company,  the  indebtedness  so  converted or exchanged
(including  all  principal  and  accrued  interest)  shall be deemed paid to the
Company as equity financing on the date of such exchange or conversion. The term
"equity  financing" means the payment of cash to the Company for the purchase of
(a)  shares  of  capital  stock of any  class  of the  Company  (whether  or not
convertible  into another class of capital  stock of the  Company),  and (b) any
option,  warrant or other  security  (other than a debt  security or  instrument
evidencing indebtedness of the Company) entitling the holder thereof to purchase
or otherwise acquire capital stock.

                         5.1.3 Other Bonuses.  The Company may pay Employee such
bonuses, if any, as the Board of Directors may, from time to time determine.

                  5.2 Benefit  Plans.  Employee shall be eligible (to the extent
he or she qualifies) to participate in any retirement,  pension,  life,  health,
accident and disability  insurance,  stock option plan or other similar employee
benefit  plans  which may be adopted by the  Company  (or any other  member of a
consolidated group of which the Company is a part) for its executive officers or
other employees; provided, that Employee shall not be eligible to participate in
the  Company's  1992 Stock  Option  Plan (or any similar  stock  option or stock
purchase plan) so long as Employee is a member of the Stock Option Committee (or
other committee governing such stock option or stock purchase plan) appointed by
the Board of Directors.

                  5.3  Expense   Reimbursement.   The  Company  shall  reimburse
Employee for all reasonable expenses incurred by Employee in connection with the
performance of his or her employment  duties,  subject to the Company's policies
and procedures in effect from time to time,  and provided that Employee  submits
supporting vouchers.

                  5.4 Vacation;  Sick Leave.  Employee shall be entitled to four
weeks of vacation, without reduction in compensation, during each calendar year.
Such vacation shall be taken at

                                        2

<PAGE>



such time as is  consistent  with the needs and  policies  of the  Company.  All
vacation  days shall  accrue based upon days of service.  The Company may,  from
time to time,  adopt policies  governing the disposition of unused vacation days
remaining at the end of the  Company's  fiscal year;  which  policies may govern
whether unused vacation days will be paid, lost, or carried over into subsequent
fiscal  years.  Employee  shall also be  entitled  to leave  from work,  without
reduction in  compensation,  due to illness to the extent allowed by the Company
consistent  with its policies and  procedures  and subject to the  provisions of
this Agreement governing termination due to disability, sickness or illness.

         6. Termination.  This Agreement shall terminate prior to the Expiration
Date upon the happening of any of the following events:

                  6.1 Death.  Automatically and without notice upon the death of
Employee;

                  6.2 Voluntary Termination by Employee. By Employee voluntarily
leaving  the employ of the  Company  with or without  the consent of the Company
(which Employee shall be entitled to do upon thirty (30) days written notice);

                  6.3  Disability.  Upon written notice of termination  from the
Company  to  Employee,  after  Employee  becomes  disabled,  either  totally  or
partially,  for a period of ninety (90) days during any one hundred  fifty (150)
day period,  so that he or she is prevented from performing his or her principal
duties pursuant to this Agreement;  provided,  that the Company's  obligation to
pay the  compensation due under Section 5 shall continue until this Agreement is
so terminated.

                  6.4 For Cause. Upon discharge of Employee,  on written notice,
by the Board of  Directors  on grounds  of: (i)  conviction  of a crime of moral
turpitude;  (ii) deliberate failure to carry out the reasonable  policies of the
Board  of  Directors,  as they  may  relate  to  Employee's  duties  under  this
Agreement;  (iii) chronic  alcohol or drug abuse;  (iv) fraud,  embezzlement  or
misappropriation  of Company assets; (v) disloyal,  dishonest or illegal conduct
in the course of his or her employment;  or (vi) a material default or breach of
any of the  covenants  made by Employee in this  Agreement.  The written  notice
delivered by the Board of Directors shall specify the ground for termination and
shall be supported by a statement of all relevant facts  constituting  cause for
termination.   Any  termination  under  this  Section  6.4  shall  be  deemed  a
termination for "cause".

                  6.5 Notice and  Opportunity to Cure. If the Company intends to
terminate this Agreement under clause (ii) or (vi) of Section 6.4, and if all of
Employee's acts or omissions giving rise to such determination to terminate this
Agreement  are,  in the  reasonable  determination  of the  Board of  Directors,
susceptible to substantially complete cure by Employee within a period of thirty
(30) days,  the written  notice given to Employee  pursuant to Section 6.4 shall
state that the effective date of termination  shall be thirty (30) days from the
date of such notice,  and such notice  shall be rescinded if Employee  effects a
substantially complete cure within such thirty (30) day period.

                                        3

                  6.6  Payment  of  Compensation  After  Termination  . Upon the
occurrence of any events set forth in Sections 6.1 through 6.4 hereof or Section
6.8, the Company shall be obligated to pay to Employee (or Employee's  estate in
the event of Employee's death) (i) the compensation due him or her under Section
5.1.1 up to the date of termination; (ii) any unpaid bonus previously awarded by
the Board of  Directors;  and  (iii)  compensation  for any  earned  but  unused
vacation,  which compensation shall be paid at the Base Salary rate in effect at
the time such unused vacation accrued.

                  6.7 Payment Upon  Termination by the Company Without Cause. In
the event this  Agreement is  terminated  by the Company for a reason other than
one of those set forth in Section 6.3 or Section 6.4 or Section 6.8, the Company
shall be required to continue to pay Employee,  as severance  compensation,  the
compensation  due him or her under Section 5.1.1, for the unexpired term of this
Agreement  (without regard to Section 3). Such severance  compensation  shall be
paid for a period equal to the number of weeks  remaining in the unexpired  term
of this Agreement  (without  regard to Section 3). Employee may elect to receive
the severance  compensation (or such part of the severance compensation as shall
then remain  unpaid) in a lump sum. Such election may be made by written  notice
to the Company,  and if such  election is made the lump sum shall be paid by the
Company within ten (10) days after such notice.

                  6.8 Change of  Control.  Notwithstanding  the  foregoing,  the
Company or its  successor,  or Employee may terminate  this  Agreement,  with or
without  cause,  in connection  with a Change of Control of the Company.  In the
event of such a  termination,  the  Company  shall pay  Employee  on the date of
termination a lump sum payment equal to the greater of (a) 2.99 times Employee's
"Base  Amount" and (b) the  compensation  due him or her under Section 5.1.1 for
the unexpired term of this Agreement (without regard to Section 3). Such payment
shall be in addition to any unpaid  amounts  otherwise  then due Employee  under
Section  5  of  this  Agreement.  Any  termination  of  this  Agreement,  except
termination  under  Sections 6.1 through 6.4,  within twelve months after either
(i) the  earliest  date on which the  Company  enters  into a letter of  intent,
memorandum of agreement,  or similar document leading to a Change of Control, or
(ii) the effective date of a Change of Control,  shall be deemed conclusively to
be a termination in connection  with a Change of Control.  If the Company or its
successor  causes  a  material  reduction  in  Employee's   responsibilities  or
compensation  after a Change of Control,  then Employee may at Employee's option
terminate  this  Agreement  under Section 6.2 any time within one hundred eighty
(180)  days  after  such  reduction,  and such  resignation  shall  be  deemed a
termination  by the  Company in  connection  with a Change of Control  and shall
entitle  Employee to the  benefits of this  Section  6.8.  For  purposes of this
Agreement, the following definitions shall apply.

                         6.8.1 "Change of Control" means (i) the  acquisition of
Voting  Securities of the Company by a Person or an Affiliated  Group  entitling
the  holder  thereof  to  elect a  majority  of the  directors  of the  Company;
provided,  that an increase in the amount of Voting  Securities held by a Person
or Affiliated Group who previously held sufficient  Voting Securities to elect a
majority  of the  directors  shall  not  constitute  a Change  of  Control;  and
provided, further, that an

                                        4

<PAGE>



acquisition of Voting Securities by one or more Persons acting as an underwriter
in connection with a sale or distribution  of such Voting  Securities  shall not
constitute  a Change of Control  under this clause (i);  (ii) the sale of all or
substantially  all  of  the  assets  of  the  Company;  or  (iii)  a  merger  or
consolidation of the Company with or into another corporation or entity in which
the stockholders of the Company  immediately before such merger or consolidation
do not own, in the aggregate,  Voting Securities of the surviving corporation or
entity (or the ultimate parent of the surviving corporation or entity) entitling
them,  in the  aggregate  (and  without  regard to whether  they  constitute  an
Affiliated  Group) to elect a  majority  of the  directors  or  persons  holding
similar powers of the surviving corporation or entity (or the ultimate parent of
the surviving corporation or entity); provided,  however, that in no event shall
any  transaction  described in clauses (i), (ii) or (iii) be a Change of Control
if all of the Persons  acquiring  Voting  Securities or assets of the Company or
merging or  consolidating  with the  Company  are one or more direct or indirect
subsidiary or parent corporations of the Company.

                         6.8.2 "Voting Securities" means shares of capital stock
or other equity  securities  entitling the holder  thereof to regularly vote for
the election of directors  (or for person  performing a similar  function if the
issuer is not a  corporation),  but does not  include the power to vote upon the
happening of some condition or event which has not yet occurred.

                         6.8.3   "Person"   means  any  natural  person  or  any
corporation,  partnership,  limited  liability  company,  trust,  unincorporated
business association or other entity.

                         6.8.4 "Affiliated  Group" means (i) a Person and one or
more other Persons in control of,  controlled  by, or under common  control with
such Person;  and (ii) two or more Persons who, by written agreement among them,
act in concert to acquire Voting  Securities  entitling them to elect a majority
of the directors of the Company.

         7. Renegotiation.  Employee shall be entitled to seek a modification of
this Agreement prior to the Expiration Date if the market value of the Company's
outstanding  capital stock exceeds  $75,000,000.  The Company will  negotiate in
good faith with Employee in connection with any such request by the Employee for
such a modification of this Agreement.

         8.  Intellectual  Property  Agreement.  Employee  acknowledges that the
Intellectual  Property Agreement  previously  executed and delivered by Employee
shall remain in effect and shall not be affected by the terms of this  Agreement
or the termination of this Agreement.

         9. Entire  Agreement.  The provisions of this Agreement,  including the
exhibits  attached to this Agreement,  constitute the entire  agreement  between
Employee and the Company with respect to the subject  matter of this  Agreement,
and  supersede  any prior oral  understanding.  No  modification,  supplement or
discharge of this Agreement shall be effective unless in writing and executed on
behalf of the party to be charged.

         10.  Waiver.  No  waiver  by  either  party of any  condition,  term or
provision of this Agreement  shall be deemed to be a waiver of any proceeding or
succeeding  breach of the same or of any other  condition,  term or provision of
this Agreement.

         11.  Assignability.  This Agreement,  and the rights and obligations of
the parties under this Agreement,  may not be assigned by Employee.  The Company
may  assign  any of its  rights and  obligations  under  this  Agreement  to any
successor or surviving corporation resulting from a merger, consolidation,  sale
of assets or stock, or other corporate  reorganization,  upon condition that the
assignee  shall  assume,  either  expressly  or by  operation of law, all of the
Company's obligations under this Agreement.

         12.   Counterparts.   This   Agreement   may  be  executed  in  several
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together shall constitute one and the same instrument.

         13. Construction.  This Agreement shall be construed in accordance with
the laws of the State of California.

         14.  Survival.  This  Section  14  and  the  covenants  and  agreements
contained in Sections  5.3, 6.6,  6.7, and 6.8 of this  Agreement  shall survive
termination of Employee's employment.

Company's  business  pursuant to, and in accordance  with,  reasonable  business
policies and procedures, as fixed from time to time by the Board of Directors of

consolidated group of which the Company is a part) for its executive officers or
other employees; provided, that Employee shall not be eligible to participate in
the  Company's  1992 Stock  Option  Plan (or any similar  stock  option or stock
purchase plan) so long as Employee is a member of the Stock Option Committee (or
other committee governing such stock option or stock purchase plan) appointed by
the Board of Directors.

                  5.3  Expense   Reimbursement.   The  Company  shall  reimburse

<PAGE>



such time as is  consistent  with the needs and  policies  of the  Company.  All
vacation  days shall  accrue based upon days of service.  The Company may,  from
time to time,  adopt policies  governing the disposition of unused vacation days
remaining at the end of the  Company's  fiscal year;  which  policies may govern
whether unused vacation days will be paid, lost, or carried over into subsequent
fiscal  years.  Employee  shall also be  entitled  to leave  from work,  without
reduction in  compensation,  due to illness to the extent allowed by the Company
consistent  with its policies and  procedures  and subject to the  provisions of
this Agreement governing termination due to disability, sickness or illness.

         6. Termination.  This Agreement shall terminate prior to the Expiration
Date upon the happening of any of the following events:

Employee;

                  6.2 Voluntary Termination by Employee. By Employee voluntarily
leaving  the employ of the  Company  with or without  the consent of the Company
(which Employee shall be entitled to do upon thirty (30) days written notice);

                  6.3  Disability.  Upon written notice of termination  from the
Company  to  Employee,  after  Employee  becomes  disabled,  either  totally  or
partially,  for a period of ninety (90) days during any one hundred  fifty (150)
day period,  so that he or she is prevented from performing his or her principal
duties pursuant to this Agreement;  provided,  that the Company's  obligation to
pay the  compensation due under Section 5 shall continue until this Agreement is
so terminated.

                  6.4 For Cause. Upon discharge of Employee,  on written notice,
by the Board of  Directors  on grounds  of: (i)  conviction  of a crime of moral
turpitude;  (ii) deliberate failure to carry out the reasonable  policies of the
Board  of  Directors,  as they  may  relate  to  Employee's  duties  under  this
Agreement;  (iii) chronic  alcohol or drug abuse;  (iv) fraud,  embezzlement  or
misappropriation  of Company assets; (v) disloyal,  dishonest or illegal conduct
in the course of his or her employment;  or (vi) a material default or breach of
any of the  covenants  made by Employee in this  Agreement.  The written  notice
delivered by the Board of Directors shall specify the ground for termination and
shall be supported by a statement of all relevant facts  constituting  cause for
termination.   Any  termination  under  this  Section  6.4  shall  be  deemed  a
termination for "cause".

                  6.5 Notice and  Opportunity to Cure. If the Company intends to
terminate this Agreement under clause (ii) or (vi) of Section 6.4, and if all of
Employee's acts or omissions giving rise to such determination to terminate this
Agreement  are,  in the  reasonable  determination  of the  Board of  Directors,
susceptible to substantially complete cure by Employee within a period of thirty
(30) days,  the written  notice given to Employee  pursuant to Section 6.4 shall
state that the effective date of termination  shall be thirty (30) days from the
date of such notice,  and such notice  shall be rescinded if Employee  effects a
substantially complete cure within such thirty (30) day period.

                  6.6  Payment  of  Compensation  After  Termination  . Upon the
occurrence of any events set forth in Sections 6.1 through 6.4 hereof or Section
6.8, the Company shall be obligated to pay to Employee (or Employee's  estate in
the event of Employee's death) (i) the compensation due him or her under Section
5.1.1 up to the date of termination; (ii) any unpaid bonus previously awarded by
the Board of  Directors;  and  (iii)  compensation  for any  earned  but  unused
vacation,  which compensation shall be paid at the Base Salary rate in effect at
the time such unused vacation accrued.

                  6.7 Payment Upon  Termination by the Company Without Cause. In
the event this  Agreement is  terminated  by the Company for a reason other than
one of those set forth in Section 6.3 or Section 6.4 or Section 6.8, the Company
shall be required to continue to pay Employee,  as severance  compensation,  the
compensation  due him or her under Section 5.1.1, for the unexpired term of this
Agreement  (without regard to Section 3). Such severance  compensation  shall be
paid for a period equal to the number of weeks  remaining in the unexpired  term
of this Agreement  (without  regard to Section 3). Employee may elect to receive
the severance  compensation (or such part of the severance compensation as shall
then remain  unpaid) in a lump sum. Such election may be made by written  notice
to the Company,  and if such  election is made the lump sum shall be paid by the
Company within ten (10) days after such notice.

                  6.8 Change of  Control.  Notwithstanding  the  foregoing,  the
Company or its  successor,  or Employee may terminate  this  Agreement,  with or
without  cause,  in connection  with a Change of Control of the Company.  In the
event of such a  termination,  the  Company  shall pay  Employee  on the date of
termination a lump sum payment equal to the greater of (a) 2.99 times Employee's
"Base  Amount" and (b) the  compensation  due him or her under Section 5.1.1 for
the unexpired term of this Agreement (without regard to Section 3). Such payment
shall be in addition to any unpaid  amounts  otherwise  then due Employee  under
Section  5  of  this  Agreement.  Any  termination  of  this  Agreement,  except
termination  under  Sections 6.1 through 6.4,  within twelve months after either
(i) the  earliest  date on which the  Company  enters  into a letter of  intent,
memorandum of agreement,  or similar document leading to a Change of Control, or
(ii) the effective date of a Change of Control,  shall be deemed conclusively to
be a termination in connection  with a Change of Control.  If the Company or its
successor  causes  a  material  reduction  in  Employee's   responsibilities  or
compensation  after a Change of Control,  then Employee may at Employee's option
terminate  this  Agreement  under Section 6.2 any time within one hundred eighty
(180)  days  after  such  reduction,  and such  resignation  shall  be  deemed a
termination  by the  Company in  connection  with a Change of Control  and shall
entitle  Employee to the  benefits of this  Section  6.8.  For  purposes of this
Agreement, the following definitions shall apply.

                         6.8.1 "Change of Control" means (i) the  acquisition of

or Affiliated Group who previously held sufficient  Voting Securities to elect a
majority  of the  directors  shall  not  constitute  a Change  of  Control;  and
provided, further, that an

                                        4

<PAGE>



acquisition of Voting Securities by one or more Persons acting as an underwriter
in connection with a sale or distribution  of such Voting  Securities  shall not
constitute  a Change of Control  under this clause (i);  (ii) the sale of all or
substantially  all  of  the  assets  of  the  Company;  or  (iii)  a  merger  or
consolidation of the Company with or into another corporation or entity in which
the stockholders of the Company  immediately before such merger or consolidation
do not own, in the aggregate,  Voting Securities of the surviving corporation or
entity (or the ultimate parent of the surviving corporation or entity) entitling
them,  in the  aggregate  (and  without  regard to whether  they  constitute  an
Affiliated  Group) to elect a  majority  of the  directors  or  persons  holding
similar powers of the surviving corporation or entity (or the ultimate parent of
the surviving corporation or entity); provided,  however, that in no event shall
any  transaction  described in clauses (i), (ii) or (iii) be a Change of Control
if all of the Persons  acquiring  Voting  Securities or assets of the Company or
merging or  consolidating  with the  Company  are one or more direct or indirect
subsidiary or parent corporations of the Company.

                         6.8.2 "Voting Securities" means shares of capital stock

business association or other entity.

more other Persons in control of,  controlled  by, or under common  control with
such Person;  and (ii) two or more Persons who, by written agreement among them,

of the directors of the Company.

         7. Renegotiation.  Employee shall be entitled to seek a modification of
this Agreement prior to the Expiration Date if the market value of the Company's
outstanding  capital stock exceeds  $75,000,000.  The Company will  negotiate in
good faith with Employee in connection with any such request by the Employee for
such a modification of this Agreement.

         8.  Intellectual  Property  Agreement.  Employee  acknowledges that the
Intellectual  Property Agreement  previously  executed and delivered by Employee
shall remain in effect and shall not be affected by the terms of this  Agreement
or the termination of this Agreement.

<PAGE>



such time as is  consistent  with the needs and  policies  of the  Company.  All
vacation  days shall  accrue based upon days of service.  The Company may,  from
time to time,  adopt policies  governing the disposition of unused vacation days
remaining at the end of the  Company's  fiscal year;  which  policies may govern
whether unused vacation days will be paid, lost, or carried over into subsequent
fiscal  years.  Employee  shall also be  entitled  to leave  from work,  without

Employee;

                  6.2 Voluntary Termination by Employee. By Employee voluntarily
leaving  the employ of the  Company  with or without  the consent of the Company
(which Employee shall be entitled to do upon thirty (30) days written notice);

                  6.3  Disability.  Upon written notice of termination  from the
Company  to  Employee,  after  Employee  becomes  disabled,  either  totally  or
partially,  for a period of ninety (90) days during any one hundred  fifty (150)
day period,  so that he or she is prevented from performing his or her principal
duties pursuant to this Agreement;  provided,  that the Company's  obligation to
pay the  compensation due under Section 5 shall continue until this Agreement is
so terminated.

                  6.4 For Cause. Upon discharge of Employee,  on written notice,
by the Board of  Directors  on grounds  of: (i)  conviction  of a crime of moral
turpitude;  (ii) deliberate failure to carry out the reasonable  policies of the
Board  of  Directors,  as they  may  relate  to  Employee's  duties  under  this
Agreement;  (iii) chronic  alcohol or drug abuse;  (iv) fraud,  embezzlement  or
misappropriation  of Company assets; (v) disloyal,  dishonest or illegal conduct
in the course of his or her employment;  or (vi) a material default or breach of
any of the  covenants  made by Employee in this  Agreement.  The written  notice
delivered by the Board of Directors shall specify the ground for termination and
shall be supported by a statement of all relevant facts  constituting  cause for
termination.   Any  termination  under  this  Section  6.4  shall  be  deemed  a
termination for "cause".

                  6.5 Notice and  Opportunity to Cure. If the Company intends to
terminate this Agreement under clause (ii) or (vi) of Section 6.4, and if all of
Employee's acts or omissions giving rise to such determination to terminate this
Agreement  are,  in the  reasonable  determination  of the  Board of  Directors,
susceptible to substantially complete cure by Employee within a period of thirty
(30) days,  the written  notice given to Employee  pursuant to Section 6.4 shall
state that the effective date of termination  shall be thirty (30) days from the
date of such notice,  and such notice  shall be rescinded if Employee  effects a
substantially complete cure within such thirty (30) day period.

                  6.6  Payment  of  Compensation  After  Termination  . Upon the
occurrence of any events set forth in Sections 6.1 through 6.4 hereof or Section
6.8, the Company shall be obligated to pay to Employee (or Employee's  estate in
the event of Employee's death) (i) the compensation due him or her under Section
5.1.1 up to the date of termination; (ii) any unpaid bonus previously awarded by
the Board of  Directors;  and  (iii)  compensation  for any  earned  but  unused
vacation,  which compensation shall be paid at the Base Salary rate in effect at
the time such unused vacation accrued.

                  6.7 Payment Upon  Termination by the Company Without Cause. In
the event this  Agreement is  terminated  by the Company for a reason other than
one of those set forth in Section 6.3 or Section 6.4 or Section 6.8, the Company
shall be required to continue to pay Employee,  as severance  compensation,  the
compensation  due him or her under Section 5.1.1, for the unexpired term of this
Agreement  (without regard to Section 3). Such severance  compensation  shall be
paid for a period equal to the number of weeks  remaining in the unexpired  term
of this Agreement  (without  regard to Section 3). Employee may elect to receive
the severance  compensation (or such part of the severance compensation as shall
then remain  unpaid) in a lump sum. Such election may be made by written  notice
to the Company,  and if such  election is made the lump sum shall be paid by the
Company within ten (10) days after such notice.

                  6.8 Change of  Control.  Notwithstanding  the  foregoing,  the
Company or its  successor,  or Employee may terminate  this  Agreement,  with or
without  cause,  in connection  with a Change of Control of the Company.  In the
event of such a  termination,  the  Company  shall pay  Employee  on the date of
termination a lump sum payment equal to the greater of (a) 2.99 times Employee's
"Base  Amount" and (b) the  compensation  due him or her under Section 5.1.1 for
the unexpired term of this Agreement (without regard to Section 3). Such payment
shall be in addition to any unpaid  amounts  otherwise  then due Employee  under
Section  5  of  this  Agreement.  Any  termination  of  this  Agreement,  except
termination  under  Sections 6.1 through 6.4,  within twelve months after either
(i) the  earliest  date on which the  Company  enters  into a letter of  intent,
memorandum of agreement,  or similar document leading to a Change of Control, or
(ii) the effective date of a Change of Control,  shall be deemed conclusively to
be a termination in connection  with a Change of Control.  If the Company or its
successor  causes  a  material  reduction  in  Employee's   responsibilities  or
compensation  after a Change of Control,  then Employee may at Employee's option
terminate  this  Agreement  under Section 6.2 any time within one hundred eighty
(180)  days  after  such  reduction,  and such  resignation  shall  be  deemed a
termination  by the  Company in  connection  with a Change of Control  and shall
entitle  Employee to the  benefits of this  Section  6.8.  For  purposes of this
Agreement, the following definitions shall apply.

                         6.8.1 "Change of Control" means (i) the  acquisition of

or Affiliated Group who previously held sufficient  Voting Securities to elect a
majority  of the  directors  shall  not  constitute  a Change  of  Control;  and
provided, further, that an

                                        4

<PAGE>



acquisition of Voting Securities by one or more Persons acting as an underwriter
in connection with a sale or distribution  of such Voting  Securities  shall not
constitute  a Change of Control  under this clause (i);  (ii) the sale of all or
substantially  all  of  the  assets  of  the  Company;  or  (iii)  a  merger  or
consolidation of the Company with or into another corporation or entity in which

do not own, in the aggregate,  Voting Securities of the surviving corporation or
entity (or the ultimate parent of the surviving corporation or entity) entitling
them,  in the  aggregate  (and  without  regard to whether  they  constitute  an
Affiliated  Group) to elect a  majority  of the  directors  or  persons  holding
similar powers of the surviving corporation or entity (or the ultimate parent of
the surviving corporation or entity); provided,  however, that in no event shall
any  transaction  described in clauses (i), (ii) or (iii) be a Change of Control
if all of the Persons  acquiring  Voting  Securities or assets of the Company or
merging or  consolidating  with the  Company  are one or more direct or indirect
subsidiary or parent corporations of the Company.

                         6.8.2 "Voting Securities" means shares of capital stock

business association or other entity.

                         6.8.4 "Affiliated  Group" means (i) a Person and one or
more other Persons in control of,  controlled  by, or under common  control with
such Person;  and (ii) two or more Persons who, by written agreement among them,

of the directors of the Company.

         7. Renegotiation.  Employee shall be entitled to seek a modification of
this Agreement prior to the Expiration Date if the market value of the Company's
outstanding  capital stock exceeds  $75,000,000.  The Company will  negotiate in
good faith with Employee in connection with any such request by the Employee for
such a modification of this Agreement.

         8.  Intellectual  Property  Agreement.  Employee  acknowledges that the
Intellectual  Property Agreement  previously  executed and delivered by Employee
shall remain in effect and shall not be affected by the terms of this  Agreement
or the termination of this Agreement.

exhibits  attached to this Agreement,  constitute the entire  agreement  between
Employee and the Company with respect to the subject  matter of this  Agreement,

Company's obligations under this Agreement.

Agreement;  (iii) chronic  alcohol or drug abuse;  (iv) fraud,  embezzlement  or
misappropriation  of Company assets; (v) disloyal,  dishonest or illegal conduct
in the course of his or her employment;  or (vi) a material default or breach of

delivered by the Board of Directors shall specify the ground for termination and
shall be supported by a statement of all relevant facts  constituting  cause for
termination.   Any  termination  under  this  Section  6.4  shall  be  deemed  a
termination for "cause".

terminate this Agreement under clause (ii) or (vi) of Section 6.4, and if all of

susceptible to substantially complete cure by Employee within a period of thirty
(30) days,  the written  notice given to Employee  pursuant to Section 6.4 shall

                  6.6  Payment  of  Compensation  After  Termination  . Upon the
occurrence of any events set forth in Sections 6.1 through 6.4 hereof or Section
6.8, the Company shall be obligated to pay to Employee (or Employee's  estate in
the event of Employee's death) (i) the compensation due him or her under Section
5.1.1 up to the date of termination; (ii) any unpaid bonus previously awarded by
the Board of  Directors;  and  (iii)  compensation  for any  earned  but  unused
vacation,  which compensation shall be paid at the Base Salary rate in effect at
the time such unused vacation accrued.

                  6.7 Payment Upon  Termination by the Company Without Cause. In
the event this  Agreement is  terminated  by the Company for a reason other than
one of those set forth in Section 6.3 or Section 6.4 or Section 6.8, the Company
shall be required to continue to pay Employee,  as severance  compensation,  the
compensation  due him or her under Section 5.1.1, for the unexpired term of this
Agreement  (without regard to Section 3). Such severance  compensation  shall be
paid for a period equal to the number of weeks  remaining in the unexpired  term
of this Agreement  (without  regard to Section 3). Employee may elect to receive
the severance  compensation (or such part of the severance compensation as shall
then remain  unpaid) in a lump sum. Such election may be made by written  notice
to the Company,  and if such  election is made the lump sum shall be paid by the
Company within ten (10) days after such notice.

                  6.8 Change of  Control.  Notwithstanding  the  foregoing,  the
Company or its  successor,  or Employee may terminate  this  Agreement,  with or
without  cause,  in connection  with a Change of Control of the Company.  In the
event of such a  termination,  the  Company  shall pay  Employee  on the date of
termination a lump sum payment equal to the greater of (a) 2.99 times Employee's
"Base  Amount" and (b) the  compensation  due him or her under Section 5.1.1 for
the unexpired term of this Agreement (without regard to Section 3). Such payment
shall be in addition to any unpaid  amounts  otherwise  then due Employee  under
Section  5  of  this  Agreement.  Any  termination  of  this  Agreement,  except
termination  under  Sections 6.1 through 6.4,  within twelve months after either
(i) the  earliest  date on which the  Company  enters  into a letter of  intent,
memorandum of agreement,  or similar document leading to a Change of Control, or
(ii) the effective date of a Change of Control,  shall be deemed conclusively to
be a termination in connection  with a Change of Control.  If the Company or its
successor  causes  a  material  reduction  in  Employee's   responsibilities  or
compensation  after a Change of Control,  then Employee may at Employee's option
terminate  this  Agreement  under Section 6.2 any time within one hundred eighty
(180)  days  after  such  reduction,  and such  resignation  shall  be  deemed a
termination  by the  Company in  connection  with a Change of Control  and shall
entitle  Employee to the  benefits of this  Section  6.8.  For  purposes of this
Agreement, the following definitions shall apply.

                         6.8.1 "Change of Control" means (i) the  acquisition of

provided,  that an increase in the amount of Voting  Securities held by a Person
or Affiliated Group who previously held sufficient  Voting Securities to elect a
majority  of the  directors  shall  not  constitute  a Change  of  Control;  and
provided, further, that an

                                        4

<PAGE>



acquisition of Voting Securities by one or more Persons acting as an underwriter
in connection with a sale or distribution  of such Voting  Securities  shall not
constitute  a Change of Control  under this clause (i);  (ii) the sale of all or
substantially  all  of  the  assets  of  the  Company;  or  (iii)  a  merger  or
consolidation of the Company with or into another corporation or entity in which
the stockholders of the Company  immediately before such merger or consolidation
do not own, in the aggregate,  Voting Securities of the surviving corporation or
entity (or the ultimate parent of the surviving corporation or entity) entitling
them,  in the  aggregate  (and  without  regard to whether  they  constitute  an
Affiliated  Group) to elect a  majority  of the  directors  or  persons  holding
similar powers of the surviving corporation or entity (or the ultimate parent of
the surviving corporation or entity); provided,  however, that in no event shall
any  transaction  described in clauses (i), (ii) or (iii) be a Change of Control
if all of the Persons  acquiring  Voting  Securities or assets of the Company or
merging or  consolidating  with the  Company  are one or more direct or indirect
subsidiary or parent corporations of the Company.

                         6.8.2 "Voting Securities" means shares of capital stock
or other equity  securities  entitling the holder  thereof to regularly vote for
the election of directors  (or for person  performing a similar  function if the
issuer is not a  corporation),  but does not  include the power to vote upon the
happening of some condition or event which has not yet occurred.

                         6.8.3   "Person"   means  any  natural  person  or  any
corporation,  partnership,  limited  liability  company,  trust,  unincorporated
business association or other entity.

                         6.8.4 "Affiliated  Group" means (i) a Person and one or
more other Persons in control of,  controlled  by, or under common  control with
such Person;  and (ii) two or more Persons who, by written agreement among them,
act in concert to acquire Voting  Securities  entitling them to elect a majority
of the directors of the Company.

         7. Renegotiation.  Employee shall be entitled to seek a modification of
this Agreement prior to the Expiration Date if the market value of the Company's
outstanding  capital stock exceeds  $75,000,000.  The Company will  negotiate in
good faith with Employee in connection with any such request by the Employee for
such a modification of this Agreement.

         8.  Intellectual  Property  Agreement.  Employee  acknowledges that the
Intellectual  Property Agreement  previously  executed and delivered by Employee
shall remain in effect and shall not be affected by the terms of this  Agreement
or the termination of this Agreement.

         9. Entire  Agreement.  The provisions of this Agreement,  including the
exhibits  attached to this Agreement,  constitute the entire  agreement  between
Employee and the Company with respect to the subject  matter of this  Agreement,
and  supersede  any prior oral  understanding.  No  modification,  supplement or
discharge of this Agreement shall be effective unless in writing and executed on
behalf of the party to be charged.

time to  time  reasonably  determine.  Employee  shall  devote  his or her  best
efforts,  skills  and  abilities,  on a  full-time  basis,  exclusively  to  the
Company's  business  pursuant to, and in accordance  with,  reasonable  business
policies and procedures, as fixed from time to time by the Board of Directors of
the Company (the "Board of Directors"). Employee covenants and agrees that he or

one-time cash bonus in the amount of Twenty-Five  Thousand Dollars  ($25,000) if
the  Company  receives  at least  One  Million  Dollars  ($1,000,000)  of equity
financing from a pharmaceutical  company. Such bonus shall be paid within thirty

(including  all  principal  and  accrued  interest)  shall be deemed paid to the
Company as equity financing on the date of such exchange or conversion. The term
"equity  financing" means the payment of cash to the Company for the purchase of
(a)  shares  of  capital  stock of any  class  of the  Company  (whether  or not
convertible  into another class of capital  stock of the  Company),  and (b) any
option,  warrant or other  security  (other than a debt  security or  instrument
evidencing indebtedness of the Company) entitling the holder thereof to purchase
or otherwise acquire capital stock.

                         5.1.3 Other Bonuses.  The Company may pay Employee such
bonuses, if any, as the Board of Directors may, from time to time determine.

                  5.2 Benefit  Plans.  Employee shall be eligible (to the extent
he or she qualifies) to participate in any retirement,  pension,  life,  health,
accident and disability  insurance,  stock option plan or other similar employee
benefit  plans  which may be adopted by the  Company  (or any other  member of a
consolidated group of which the Company is a part) for its executive officers or
other employees; provided, that Employee shall not be eligible to participate in
the  Company's  1992 Stock  Option  Plan (or any similar  stock  option or stock
purchase plan) so long as Employee is a member of the Stock Option Committee (or
other committee governing such stock option or stock purchase plan) appointed by
the Board of Directors.

                  5.3  Expense   Reimbursement.   The  Company  shall  reimburse
Employee for all reasonable expenses incurred by Employee in connection with the
performance of his or her employment  duties,  subject to the Company's policies

<PAGE>



such time as is  consistent  with the needs and  policies  of the  Company.  All
vacation  days shall  accrue based upon days of service.  The Company may,  from
time to time,  adopt policies  governing the disposition of unused vacation days
remaining at the end of the  Company's  fiscal year;  which  policies may govern
whether unused vacation days will be paid, lost, or carried over into subsequent
fiscal  years.  Employee  shall also be  entitled  to leave  from work,  without
reduction in  compensation,  due to illness to the extent allowed by the Company
consistent  with its policies and  procedures  and subject to the  provisions of
this Agreement governing termination due to disability, sickness or illness.

         6. Termination.  This Agreement shall terminate prior to the Expiration
Date upon the happening of any of the following events:

                  6.1 Death.  Automatically and without notice upon the death of
Employee;

                  6.2 Voluntary Termination by Employee. By Employee voluntarily
leaving  the employ of the  Company  with or without  the consent of the Company
(which Employee shall be entitled to do upon thirty (30) days written notice);

                  6.3  Disability.  Upon written notice of termination  from the
Company  to  Employee,  after  Employee  becomes  disabled,  either  totally  or
partially,  for a period of ninety (90) days during any one hundred  fifty (150)
day period,  so that he or she is prevented from performing his or her principal
duties pursuant to this Agreement;  provided,  that the Company's  obligation to
pay the  compensation due under Section 5 shall continue until this Agreement is
so terminated.

                  6.4 For Cause. Upon discharge of Employee,  on written notice,
by the Board of  Directors  on grounds  of: (i)  conviction  of a crime of moral
turpitude;  (ii) deliberate failure to carry out the reasonable  policies of the
Board  of  Directors,  as they  may  relate  to  Employee's  duties  under  this
Agreement;  (iii) chronic  alcohol or drug abuse;  (iv) fraud,  embezzlement  or
misappropriation  of Company assets; (v) disloyal,  dishonest or illegal conduct
in the course of his or her employment;  or (vi) a material default or breach of
any of the  covenants  made by Employee in this  Agreement.  The written  notice
delivered by the Board of Directors shall specify the ground for termination and
shall be supported by a statement of all relevant facts  constituting  cause for
termination.   Any  termination  under  this  Section  6.4  shall  be  deemed  a
termination for "cause".

                  6.5 Notice and  Opportunity to Cure. If the Company intends to
terminate this Agreement under clause (ii) or (vi) of Section 6.4, and if all of
Employee's acts or omissions giving rise to such determination to terminate this
Agreement  are,  in the  reasonable  determination  of the  Board of  Directors,
susceptible to substantially complete cure by Employee within a period of thirty
(30) days,  the written  notice given to Employee  pursuant to Section 6.4 shall
state that the effective date of termination  shall be thirty (30) days from the
date of such notice,  and such notice  shall be rescinded if Employee  effects a
substantially complete cure within such thirty (30) day period.

                                        3

<PAGE>



                  6.6  Payment  of  Compensation  After  Termination  . Upon the
occurrence of any events set forth in Sections 6.1 through 6.4 hereof or Section
6.8, the Company shall be obligated to pay to Employee (or Employee's  estate in
the event of Employee's death) (i) the compensation due him or her under Section
5.1.1 up to the date of termination; (ii) any unpaid bonus previously awarded by
the Board of  Directors;  and  (iii)  compensation  for any  earned  but  unused
vacation,  which compensation shall be paid at the Base Salary rate in effect at
the time such unused vacation accrued.

                  6.7 Payment Upon  Termination by the Company Without Cause. In
the event this  Agreement is  terminated  by the Company for a reason other than
one of those set forth in Section 6.3 or Section 6.4 or Section 6.8, the Company
shall be required to continue to pay Employee,  as severance  compensation,  the
compensation  due him or her under Section 5.1.1, for the unexpired term of this
Agreement  (without regard to Section 3). Such severance  compensation  shall be
paid for a period equal to the number of weeks  remaining in the unexpired  term
of this Agreement  (without  regard to Section 3). Employee may elect to receive
the severance  compensation (or such part of the severance compensation as shall
then remain  unpaid) in a lump sum. Such election may be made by written  notice
to the Company,  and if such  election is made the lump sum shall be paid by the
Company within ten (10) days after such notice.

                  6.8 Change of  Control.  Notwithstanding  the  foregoing,  the
Company or its  successor,  or Employee may terminate  this  Agreement,  with or
without  cause,  in connection  with a Change of Control of the Company.  In the
event of such a  termination,  the  Company  shall pay  Employee  on the date of
termination a lump sum payment equal to the greater of (a) 2.99 times Employee's
"Base  Amount" and (b) the  compensation  due him or her under Section 5.1.1 for
the unexpired term of this Agreement (without regard to Section 3). Such payment
shall be in addition to any unpaid  amounts  otherwise  then due Employee  under
Section  5  of  this  Agreement.  Any  termination  of  this  Agreement,  except
termination  under  Sections 6.1 through 6.4,  within twelve months after either
(i) the  earliest  date on which the  Company  enters  into a letter of  intent,
memorandum of agreement,  or similar document leading to a Change of Control, or
(ii) the effective date of a Change of Control,  shall be deemed conclusively to
be a termination in connection  with a Change of Control.  If the Company or its
successor  causes  a  material  reduction  in  Employee's   responsibilities  or
compensation  after a Change of Control,  then Employee may at Employee's option
terminate  this  Agreement  under Section 6.2 any time within one hundred eighty
(180)  days  after  such  reduction,  and such  resignation  shall  be  deemed a
termination  by the  Company in  connection  with a Change of Control  and shall

account  owned or  controlled  by Cohen or over which  Cohen  holds any power to

or entity the right to sell,  or giving any other  person or entity the right to
purchase,  Common  Shares  of the  Company,  except  for  such  sales  or  other
transactions  in or  pertaining  to Common  Shares of the  Company  for which no

prospects,  (b)  recommend  that anyone sell or refrain from  purchasing  Common
Shares

                                        2

<PAGE>



of the Company, (c) engage (directly, or indirectly through the participation in
any  group,  or  ownership  of any  direct  or  indirect  interest  in  account,
corporation,  partnership or other entity) in any short sale of Common Shares of
the  Company,  (d)  acquire,  directly  or  indirectly,  as part  of a group  or
otherwise,  beneficial  ownership of 5% or more of any outstanding  class of the
Company  equity  securities,   and  Cohen  will  not  join  in  any  group  that
beneficially  owns 5% or more of any such  class of equity  securities,  and (e)
participate  in or support any group or slate of  candidates  seeking to replace
any incumbent director of the Company.  Beneficial ownership shall be determined
under Section 13(d) of the Exchange Act and the rules promulgated thereunder.

         7.  Injunctive  Relief.  Cohen  acknowledges  that the Company would be
irreparably  harmed by the disclosure or use of any Confidential  Information in
violation  of this  Agreement.  Cohen  agrees  that,  in  addition  to all other
remedies  available  to the Company at law or in equity,  the  Company  shall be
entitled to equitable relief  enjoining any use,  appropriation or disclosure of
Confidential Information in violation of this Agreement.

         8.  Certain  Remedies  for Breach.  Cohen agrees that the Options to be
granted  under  Subsection  1 are being  granted  in  consideration  of  Cohen's
agreement to comply with the  provisions of this  Agreement and the Stock Option
Agreement,  and Donna  Cohen's  Agreement to comply with the  provisions  of the
Stock  Lock-Up  Agreement,  and  Cohen's  right  to  exercise  such  Options  is
conditioned  upon  Cohen's full  compliance  with this  Agreement  and the Stock
Option  Agreement,  and Donna  Cohen's full  compliance  with the Stock  Lock-Up
Agreement.  Because a breach of the  provisions of this  Agreement and the Stock
Lock-Up  Agreement could not adequately be compensated by money damages,  and/or
because  determination  of any monetary damages incurred by the Company would be
difficult to calculate,  in the event of a breach of this Agreement or the Stock
Lock-Up  Agreement,  the Company  shall be entitled  (in addition to, and not in
lieu of, any other right or remedy  available  to it under this  Agreement,  the
Stock Option Agreement,  and the Stock Lock-Up Agreement to cancel any or all of
the Options  granted to Cohen under this  Agreement  which have not  theretofore
been exercised in accordance with their terms and conditions.  Such cancellation
may be effected  without any  compensation to Cohen or Donna Cohen for the value
of such Options or the value of the Shares or other  securities  underlying such
Options.

         9.  Reasonable  Restrictions.  Cohen  agrees  that  the  provisions  of
Sections 4, 5 and 6 are  reasonable and necessary to protect the Company and its
business.  It is the desire and intent of the  parties  that the  provisions  of
Sections 4, 5 and 6 shall be enforced to the fullest extent  permitted under the
public policies and laws applied in each  jurisdiction  in which  enforcement is
sought.  If any restriction  contained in Sections 4, 5 and 6 shall be deemed to
be  invalid,  illegal  or  unenforceable  by  reason of the  extent or  duration
thereof,  or otherwise,  then the court making such determination shall have the
right to reduce such extent or other  provisions  hereof and in its reduced form
such restriction shall then be enforceable in the manner contemplated hereby.

         10. Release. Cohen hereby forever releases,  acquits and discharges the
Company and each officer,  director and employee of the Company from any and all
liability, whether in

                                        3

<PAGE>


contract,  tort,  or  otherwise,  that Cohen may now have or which may hereafter
accrue,  arising  out of or  connected  with the service of Cohen as a director,
officer or employee of the Company, or as a shareholder of the Company, prior to
the date of this  Agreement.  Cohen further agrees not to participate as a party
adverse to the Company in any lawsuit or other  proceeding and not to finance or
otherwise  assist  any party  adverse  to the  Company  in any  lawsuit or other
proceeding, other than proceedings pertaining to any actual or alleged breach of
this  Agreement  or the Stock  Option  Agreement.  The  Company  hereby  forever
releases,  acquits and discharges  Cohen from any and all liability,  whether in
contract,  tort,  or  otherwise,  that the  Company  may now  have or which  may
hereafter  accrue,  arising out of or  connected  with the service of Cohen as a
director,  officer  or  employee  of the  Company,  or as a  shareholder  of the
Company,  prior to the date of this Agreement.  The Company and Cohen agree that
this  release  includes all claims of every kind and nature,  past,  present and
future, known or unknown, suspected or unsuspected.  With respect to the subject
matter of this release, the Company and Cohen expressly waive any and all rights
or claims under Section 1542 of the California Civil Code, which provides:

         "A general  release does not extend to claims  which the creditor  does
         not know or suspect to exist in his favor at the time of executing  the
         release,  which  if  known by him must  have  materially  affected  his
         settlement with the debtor."

This Section 10 shall not affect Cohen's rights to indemnification  arising from
his acting as an officer,  director or employee of the  Company,  as provided in
the  articles of  incorporation  and bylaws of the Company or Section 317 of the
California  Corporations Code. The Company's articles of incorporation authorize
the  corporation  to  indemnify  officers and  directors  to the fullest  extent
permitted under California law, and the Company agrees to so indemnify Cohen but
only to the same extent as such  indemnification  is provided to other  officers
and  directors  of the  Company;  provided,  however,  that the Company does not
presently  maintain  insurance  indemnifying  its  officers and  directors  from
liabilities arising from their acts and omissions,  and the Company shall not be
obligated to provide  Cohen with any such  insurance  even if such  insurance is
obtained for other officers and directors in the future.

         11. Tax  Withholding.  Cohen agrees that the Company may withhold  from
the severance payments all federal, state, and local income,  employment,  FICA,
SDI and other  taxes.  Cohen also  agrees to remit to the  Company on demand all
federal,  state, and local income tax withholdings arising from the grant of the
Option, as may be required by applicable law. In this regard, Cohen acknowledges
that the exercise price of the Option on the date of grant is less than the fair
market  value per share of the Shares  issuable  upon  Cohen's  exercise  of the
Option.

         12. Transfers of Restricted Shares. The Company agrees that it will not
act to materially delay or prohibit any sale of restricted  Company Shares owned
by Cohen or Donna  Cohen,  and will not  impose any fee as a  condition  of such
transfer,  provided  that  the  sale (a)  does  not  violate  the  terms of this
Agreement or the Stock Lock-Up  Agreement,  (b) is made in compliance  with Rule
144(k) under the Securities  Act, (c) does not violate  Section 10 or Section 16
of the Exchange Act or any regulation  thereunder,  and (d) does not violate the
securities or "Blue Sky" laws of any state. For the purpose of this Section, the
Company  shall not be deemed to have caused a  restriction  or delay on any sale
resulting  from  (i)  the  placement  of  a  legend  on  any  stock  certificate
restricting  sales  or  transfers  without  registration  or an  exemption  from
registration  under the Securities Act and applicable  state  securities or Blue
Sky laws,  (ii) the entry of any stop transfer  order or legend on the books and
records of the  transfer  agent of the Shares  relating to the  restrictions  on
transfer  described in (i), and (iii) any requirement  that Cohen or Donna Cohen
provide  the  transfer  agent for the  Shares  with an opinion of counsel to the
effect  that  the  proposed  sale may be made  without  registration  under  the
Securities Act or the securities or Blue Sky laws of any state.

         13.  Entire  Agreement.  The  provisions of this  Agreement,  the Stock
Option Agreement and the Stock Lock-Up Agreement constitute the entire agreement
between  Cohen  and the  Company  with  respect  to the  subject  matter of this
Agreement,  and  supersede  any  prior  oral  understanding.   No  modification,
supplement or discharge of this Agreement  shall be effective  unless in writing
and executed on behalf of the party to be charged.

         14.  Waiver.  No  waiver  by  either  party of any  condition,  term or
provision of this Agreement  shall be deemed to be a waiver of any proceeding or
succeeding  breach of the same or of any other  condition,  term or provision of
this Agreement.

         15.  Successors and Assigns.  This Agreement  shall be binding upon the
heirs,  executors,  administrators,  successors and assigns of Cohen,  and shall
inure to the benefit of the successors and assigns of the Company.

         16.   Counterparts.   This   Agreement   may  be  executed  in  several
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together shall constitute one and the same instrument.

         17. Construction.  This Agreement shall be construed in accordance with
the laws of the State of California.

         18. Notices.  Any notices or other communication  required or permitted
to be given  under  this  Agreement  shall be in  writing  and  shall be  deemed
