Item 1.  Business

Overview

     We are  developing  cell  transplantation  technology  for  treating  human
diseases that are  characterized by cell dysfunction or cell death and for which
current  therapies are either  inadequate  or  nonexistent.  Our products  under
development include:


- NeuroCell-PD for Parkinson's disease
- Porcine neural cells for stroke
- Porcine neural cells for focal epilepsy
- Porcine neural cells for chronic intractable pain
- Porcine spinal cord cells for spinal cord injury
- NeuroCell-HD for Huntington's disease
- Human liver cells for cirrhosis
- Porcine liver cells for acute liver failure
- Human muscle cells for cardiac disease
- Porcine retinal pigment epithelial cells,
  or porcine RPE cells, for macular degeneration.



     Although   scientists   have   demonstrated   the   feasibility   of   cell
transplantation,  an  inadequate  supply  of  human  donor  cells  has  hampered
widespread use of cell  transplantation  in clinical  applications.  To overcome
this  constraint,  we have pioneered the use of porcine (pig) cells for clinical
transplantation.  Because porcine cells are functionally similar to human cells,
we  believe  that pigs will be a  reliable  source of a wide range of cell types
suitable for  transplantation  into humans. We have shown in preclinical studies
and  clinical  trials  that   transplanted   porcine  cells  appear  capable  of
integrating into the surrounding  tissue and addressing the functional  deficits
caused by cell damage or cell death.

     After   receiving   clearance   from  the  United   States  Food  and  Drug
Administration,  commonly  referred  to as the FDA,  to  conduct  the first ever
clinical trial of  transplanted  porcine neural cells in humans,  we completed a
three-year,  twelve-patient, Phase 1 clinical trial to evaluate NeuroCell-PD for
the treatment of Parkinson's  disease in 1999. Based on encouraging results from
this Phase 1 clinical  trial, we initiated an 18-patient,  pivotal,  randomized,
double-blinded,  placebo-controlled  Phase 2/3 clinical trial of NeuroCell-PD in
1998. Treatment of patients in this Phase 2/3 clinical trial has been completed,
and the trial is expected to be unblinded in March 2001.

     In recognition of its potential to address an important unmet medical need,
the FDA has designated  NeuroCell-PD as a fast track product.  Fast track status
expedites  the  regulatory  review  of new  drugs  which  are  intended  for the
treatment of serious or  life-threatening  conditions and which  demonstrate the
potential to address unmet medical  needs.  The FDA has also granted orphan drug
designation  for  NeuroCell-PD  for advanced  Parkinson's  disease,  which is an
incentive  provided to manufacturers  to undertake  development and marketing of
products  to treat  relatively  rare  diseases.  Under  current  law,  the first
developer to receive FDA  marketing  approval  for a  designated  orphan drug is
generally  entitled to a  seven-year  exclusive  marketing  period in the United
States.

     We are developing our lead product candidate,  NeuroCell-PD, as well as our
NeuroCell-HD  product  candidate,  in a joint venture with Genzyme  Corporation,
which is called  Diacrin/Genzyme  LLC.  As of  December  31,  2000,  Genzyme has
contributed  $29.7  million and we have  contributed  $6.5  million to the joint
venture which has been used to develop these product candidates.

     We are also conducting four separate  six-patient,  Phase 1 clinical trials
to evaluate fetal porcine neural cells for stroke recovery, fetal porcine neural
cells for the treatment of focal  epilepsy,  human liver cells for cirrhosis and
human  muscle  cells for cardiac  disease.  We have  received  FDA  clearance to
initiate  three  six-patient  Phase 1 clinical  trials to evaluate fetal porcine
neural cells for chronic  intractable pain, porcine spinal cord cells for spinal
cord injury




and  porcine  liver  cells for the  treatment  of acute  liver  failure.  We are
conducting  preclinical  studies to evaluate the use of fetal  porcine RPE cells
for the treatment of macular degeneration.

     We are also  developing a proprietary  technology  designed to modulate the
human immune system in order to prevent rejection of transplanted  cells without
the use of  immunosuppressive  drugs. This technology,  which we refer to as our
immunomodulation   technology,   involves  the   selective   treatment  of  cell
populations prior to transplantation to prevent the patient's immune system from
rejecting the  transplanted  cells.  Our approach  would  eliminate the need for
long-term  immunosuppressive  drugs, which may leave the patient vulnerable to a
wide range of  undesirable  side  effects,  including  increasing  the patient's
susceptibility  to  infections  and  cancer.  We have shown in  preclinical  and
clinical  studies  the  ability of our  immunomodulation  technology  to prevent
rejection of transplanted  porcine cells without  compromising the immune system
or causing  undesirable side effects.  We published  scientific  evidence in The
Journal of Immunology in June 1999 that describes how this technology might work
to allow survival of transplanted cells.

     We were  incorporated in October 1989. Our principal  executive offices are
located at Building  96, 13th Street,  Charlestown  Navy Yard,  Charlestown,  MA
02129, and our telephone number at that location is (617) 242-9100.

Diacrin's Transplantation Technology

     We  have   pioneered   the  use  of  fetal   porcine   cells  for  clinical
transplantation  for the treatment of human disease.  In March 1995, we received
the first FDA  clearance  to  transplant  porcine  cells  into  humans.  We have
developed critical  technology  relating to the production process for obtaining
and screening  porcine cells. We are also developing  technology to modulate the
human immune system to enable porcine cell transplantation into the body without
the use of immunosuppressive drugs.

     Each step of our production process has been designed based on proposed FDA
guidelines  and is  controlled  in order to  obtain  cells  suitable  for  human
transplantation.  We have  developed  procedures  to screen pigs for  infectious
agents  and  then  quarantine  qualified  donor  pigs at our  biomedical  animal
facilities.  We harvest  cells of  appropriate  age and type under  current good
manufacturing procedures, commonly referred to as cGMP, at either our facilities
or those of our joint venture with Genzyme.

     We perform our  screening  procedures  in  accordance  with FDA  guidelines
covering  xenotransplantation.  These  guidelines  have been designed to prevent
contamination of transplanted cellular products with infectious agents that have
the  potential  to affect  human  cells.  The FDA requires all sponsors of human
clinical trials involving porcine tissue, including us, to test for the presence
of porcine  endogenous  retroviruses,  commonly  known as PERV, in patient blood
samples. To date, none of our patients have shown any sign of PERV.




     Current  transplantation  technology  generally requires that the patient's
immune system be suppressed in order to avoid rejection of transplanted cells. T
cells,  the main  cells  involved  in  directing  the  body's  immune  response,
recognize and bind to cell surface proteins known as MHC class I proteins.  When
T cells recognize foreign MHC class I proteins, a cascade of events is triggered
which ultimately  results in destruction of the transplanted  cells that display
these  foreign  proteins.   Cyclosporine,  a  standard  immunosuppressive  drug,
prevents  this  rejection  process.  Using  cyclosporine,  we have  demonstrated
survival of transplanted porcine cells in a variety of preclinical animal models
and have histologically documented survival of transplanted porcine fetal neural
cells in a deceased patient who had received NeuroCell-PD.

     We are also developing proprietary technology to modulate the immune system
to avoid  rejection of transplanted  cells.  We treat isolated cell  populations
prior to  transplantation  with antibody  fragments directed against MHC class I
proteins.  This  technology  is designed  to  eliminate  the need for  long-term
immunosuppressive  drugs. To date the use of our immunomodulation  technology in
clinical trials has not resulted in any undesirable side effects. Our scientists
and academic  collaborators have performed  preclinical  studies which show that
cells that have been pretreated using our  immunomodulation  technology prior to
transplantation survived in several animal models without immunosuppression. The
long-term survival of the transplanted cells seen in these studies suggests that
the recipient's  immune system has "learned" to accept the transplant.  Thus, we
believe that treatment of cells with antibody fragments prior to transplantation
will induce a state of graft-specific immunological tolerance, which would allow
continued survival of the transplanted cells.

     In connection with our Phase 1 clinical  trials,  six  Parkinson's  disease
patients,  six Huntington's disease patients,  three focal epilepsy patients and
five stroke patients have been  transplanted  with  antibody-pretreated  porcine
neural cells, using no immunosuppressive drugs. Preliminary indications from the
Phase 1 NeuroCell-PD  clinical trial suggest that the improvement in Parkinson's
disease   symptoms   that   has   occurred   in   patients   transplanted   with
antibody-treated NeuroCell-PD is comparable to the improvement shown in patients
transplanted with NeuroCell-PD with immunosuppressive drugs.

NeuroCell-PD for Parkinson's Disease

     Parkinson's  disease is a  neurodegenerative  disease that results from the
loss of  dopamine-producing  neural cells within an area of the brain called the
substantia nigra, causing the loss of coordinated muscular activity. The disease
is generally  characterized  by  progressively  worsening  physical  conditions,
including  difficulty  in  movement,  muscular  rigidity,  tremors and  postural
instability. In addition to a decreased quality of life, Parkinson's disease may
also result in premature  death. In the United States,  there are  approximately
500,000 people afflicted with Parkinson's  disease.  The majority of Parkinson's
disease patients are first diagnosed between the ages of 45 and 65. NeuroCell-PD
will be directed to the treatment of patients with advanced Parkinson's disease,
which we estimate to be approximately  130,000 patients in the United States. We
expect the  prevalence of  Parkinson's  disease to increase with the  increasing
average age of the population.

     Current therapies consist of administration of levodopa,  commonly known as
L-dopa, a precursor of dopamine, and dopamine analogues. However, L-dopa is only
effective  for a limited  period  of time,  with most  patients  experiencing  a
progressive  reduction in drug efficacy over a 10 to 15 year period,  due to the
cumulative  loss of viable  neural cells and  tolerance to L-dopa.  In addition,
L-dopa  therapy  can  result  in  severe  side-effects,  including  uncontrolled
movements, also known as dyskinesia, and hallucinations.  No currently available
therapy prevents progression of the neurological  deficits caused by Parkinson's
disease.

     Clinical  researchers have shown that transplantation of human fetal neural
cells into  Parkinson's  disease  patients is effective in treating the disease.
For example,  Swedish  researchers  have  demonstrated  survival and function of
transplanted  human fetal neural  cells in  Parkinson's




disease  patients in an ongoing  study which  commenced in 1989.  This study has
shown  long-term  survival of cells and  improvements  in patients'  conditions.
However,  the lack of  availability  of human  fetal  neural  cells and  ethical
concerns  regarding the use of human fetal tissue limit its widespread  clinical
application.  Moreover,  even when available,  the quality of human fetal neural
cells is variable, which may limit the clinical effectiveness of this treatment.

     Our  approach to the  treatment  of  Parkinson's  disease is to produce and
transplant NeuroCell-PD to replace the function of those neural cells damaged by
the  disease.  We and  our  collaborators  have  shown  in  animal  models  that
transplanted  porcine fetal neural cells become  integrated into the surrounding
brain tissue and correct functional  deficits.  While NeuroCell-PD is not a cure
for Parkinson's disease, the goal of this treatment is to significantly  improve
the clinical condition of patients with severe  Parkinson's  disease in order to
allow them to function independently.

     We harvest  porcine fetal neural cells under cGMP for  transplantation.  We
have developed a specially  qualified porcine fetal cell source in collaboration
with Tufts University  School of Veterinary  Medicine.  The porcine fetal neural
cells,  which are  isolated  from a  specific  region of the  developing  brain,
function  the same as human fetal  neural  cells.  These cells are  isolated and
vialed in a suite of clean rooms designed to prevent contamination of the cells.
The vialed cells are then transported to a hospital where a neurosurgeon injects
them into a precise area of the  patient's  brain.  This is  accomplished  using
standard stereotactic surgical equipment and techniques.

     Our twelve-patient Phase 1 clinical trial of NeuroCell-PD,  which completed
enrollment  in  October  1996,  was the  first  FDA-authorized  trial  involving
transplantation of porcine cells into humans. Although the study was designed to
evaluate  the  safety of  NeuroCell-PD,  we also  evaluated  its  effects on the
Parkinson's  disease symptoms of the transplant  recipients.  Each of the twelve
patients  in the study  received  approximately  12 million  cells  transplanted
unilaterally  (one  side  of the  brain).  A  histological  study  of one of the
patients, who died of causes unrelated to the transplant, published in the March
1997 issue of Nature  Medicine,  demonstrated  that  porcine  fetal neural cells
survived  and  matured in his  brain.  This  study  marked  the first  published
documentation  of the survival of cells  transplanted  from another species into
the human brain and the appropriate  growth of the non-human neural cells in the
brain of a Parkinson's disease patient.

     Our clinical  evaluators  observed clinical  improvement in the Parkinson's
disease patients beginning approximately three months after transplantation. The
patients who have been followed demonstrated  statistically significant clinical
improvement  at one year,  two years and three  years  post  transplantation  as
measured by the Unified Parkinson's Disease Rating Scale.

     In 1999, our joint venture with Genzyme completed accrual of patients in an
18-patient pivotal,  randomized,  double-blinded,  placebo-controlled  Phase 2/3
clinical trial involving the transplantation of NeuroCell-PD in conjunction with
cyclosporine  immunosuppression  versus a  control  group.  Each of the  treated
patients in this trial  received  approximately  48 million  cells  transplanted
bilaterally  (both sides of the brain).  Treatment of patients in this Phase 2/3
clinical  trial has been  completed and the trial is expected to be unblinded in
March 2001.




     In recognition of its potential to address an important unmet medical need,
the FDA has  designated  NeuroCell-PD  a fast  track  product.  The FDA has also
granted  orphan drug  designation  for  NeuroCell-PD  for  advanced  Parkinson's
disease.

Porcine Neural Cells for Stroke

     Stroke is the third  leading cause of death in the United  States,  ranking
behind  coronary  artery  disease  and cancer.  It is also the leading  cause of
long-term disability in the United States. Approximately 600,000 people suffer a
stroke  each year and there are 4.4 million  people  that have been  disabled by
stroke in the United States.  A stroke occurs when the blood supply to a part of
the brain is suddenly interrupted.  When blood flow to the brain is interrupted,
some brain cells die immediately,  while others will die days or weeks after the
stroke.  The death of these  brain  cells  creates a void which  becomes a fluid
filled cavity in the brain.

     Current therapies for stroke target the early events that occur at the time
of the stroke.  Timely intervention with surgery or with non-invasive  therapies
that restore blood flow can limit the cell death that occurs.  Therapies include
surgical  intervention to remove a clearly defined clot or anticoagulant therapy
to "break up" the clot formation.  All current therapies are most effective when
administered  as  quickly  as  possible  after the  stroke,  and there is a time
post-stroke  (12-24 hours) after which  therapeutic  intervention  is useless in
limiting brain cell death.

     Our approach of using porcine fetal neural cell transplantation is based on
the premise that many patients who have survived but not fully  recovered from a
stroke may benefit from the introduction of cells that may repair or replace the
damaged neural  circuitry.  We and others have  demonstrated  in numerous animal
studies the feasibility of repairing and restoring  function to a stroke-damaged
brain.  In an animal model of stroke,  we have shown that  transplanted  porcine
fetal neural cells survive at high  frequency.  These cells not only survived in
the brain cavity, but formed solid grafts that integrated appropriately with the
normal brain tissue  surrounding the cavity.  We have observed  extensive neural
outgrowth from the graft to the surrounding brain and behavioral improvements in
a rat model of stroke after  transplantation  of porcine fetal neural cells. The
transplanted   cells  have  the  capacity  to  form  billions  of  new  synaptic
connections  as well as to release  other  chemicals  that  promote  neural cell
growth.

     We initiated a  six-patient,  Phase 1 clinical  trial using  porcine  fetal
neural  cells  in  stroke  patients  in  Boston,  Massachusetts  at Beth  Israel
Deaconess Medical Center and Brigham and Women's  Hospital.  In April 2000, this
Phase 1 clinical  trial was suspended by the FDA to allow  investigation  of the
cause of two serious adverse events.  At the time the trial was suspended we had
treated 5 patients.  Both patients who suffered  adverse  events have  recovered
from  their  adverse  event.  We  have  reviewed  the  scientific  and  clinical
information  relating to these adverse  events and concluded that they were most
likely  associated with the surgical  procedure used to implant the cells.  This
conclusion  has been supported by an  independent  group of experts  convened by
Diacrin.  We are now  working  with  the FDA to  obtain  clearance  to  continue
recruiting  patients in this trial,  although there is no assurance that the FDA
will agree with our conclusions and allow us to resume the trial.



Porcine Neural Cells for Focal Epilepsy

     Epilepsy  is a  chronic,  recurrent  disorder  characterized  by  excessive
neuronal discharge in the brain, causing muscle spasms or convulsions. Epileptic
seizures are usually associated with some alteration of consciousness.  Epilepsy
is one of the most common neurological  disorders and is estimated to affect 1.8
million people in the United States. The only currently available treatments for
epilepsy  are drug  therapy and surgery.  A number of  anti-epileptic  drugs are
available  to treat  seizures.  However,  these  drugs fail to  control  seizure
activity in a significant  number of patients and frequently  cause side effects
that range in severity from minimal  impairment of the central nervous system to
death from liver failure. By several estimates,  approximately  200,000 patients
with complex partial  epilepsy have seizures that are not  well-controlled  with
currently  available drug therapy.  The seizures are of many different types and
arise as a result of diverse  pathologies.  Other  therapies  available to these
patients  are  surgical  removal of portions of the temporal or frontal lobe and
vagal  nerve  stimulation   through  an  implantable  device.  We  believe  that
transplantation  of porcine  fetal neural cells will be preferable to removal of
brain tissue if the transplantation is shown to be safe and efficacious.

     Our initial  therapeutic focus in this area is in the treatment of patients
with complex partial  seizures,  which are  characterized by a focal onset and a
loss of  consciousness.  Because focal  epilepsy is  characterized  by excessive
electrical  activity  in a  localized  area of the brain and the  spread of this
activity  through the brain,  our approach to therapy is to  transplant  porcine
fetal neural cells in order to exert an inhibitory effect on the  hyperexcitable
brain region.

     We have  initiated a  six-patient,  Phase 1 clinical trial of porcine fetal
neural  cells at Beth Israel  Deaconess  Medical  Center and Brigham and Women's
Hospital in Boston.  As of February 28, 2001, we had treated  three  patients in
this trial.

Porcine Neural Cells for Chronic Intractable Pain

     Chronic  intractable  pain can be caused by  neuropathologic  processes  in
tissues and organs, or by prolonged dysfunction of peripheral or central nervous
system  pathways.  Chronic  intractable  pain is  characterized  by the death of
inhibitory neural cells in the spinal cord and cannot be relieved even with pain
killers such as morphine. It is estimated that 500,000 individuals in the United
States  suffer  from  unrelieved  chronic  pain as a result of these  peripheral
neuropathies.  Peripheral neuropathies can also be associated with diseases such
as HIV,  diabetes and cancer.  Many  patients  with  malignant  disease  develop
chronic  intractable  pain, and the prevalence of severe pain in cancer patients
increases  as the  disease  progresses  to the  advanced  stages.  There  are an
estimated 1.6 million cancer patients who experience chronic intractable pain in
the United States.

     We intend to use porcine  fetal neural  cells to alleviate  chronic pain by
repopulating inhibitory neural cells to recover appropriate neurotransmission in
the spinal  cord.  We have  demonstrated  in animal  studies a favorable  safety
profile and survival of porcine fetal inhibitory neural cells  transplanted into
the dorsal horn of the spinal cord. Our  Investigational  New Drug  Application,
commonly referred to as IND, has been cleared by the FDA and we plan to initiate
a six-patient,  Phase 1 clinical trial in 2001 at New England  Medical Center in
Boston and at Washington University Medical Center in St. Louis, Missouri.




Porcine Spinal Cord Cells for Spinal Cord Injury

     The prevalence of spinal cord injury,  commonly known as SCI, in the United
States is approximately  200,000,  with 13,000 additional SCIs annually.  Nearly
80% of the injured  patients  are males in their late 20s to early 30s.  Greater
than 95% of these SCIs are  compression  injuries,  the  remainder  are cases in
which the cord is severed.  The spinal cord in the neck is  vulnerable to injury
because of its extreme  mobility,  and  approximately  80% of SCIs occur in this
region.  Loss of sensorimotor  neuron  function due to injury  requires  lengthy
hospitalization  after the initial incident as well as extensive  rehabilitative
care.  Furthermore,  all  victims  of SCI face a  lifelong  series  of acute and
chronic non-neurological complications that can be life-threatening.

     The primary objective of current therapies available for SCIs is to prevent
further  injury  by  physically  stabilizing  the spine  and by  inhibiting  the
inflammatory  response that results from the injury. These strategies attempt to
establish  optimal  conditions  for  functional  recovery and improve  patients'
rehabilitative  potential.  Surgery is  designed  to protect  the  patient  from
further   injury   through   immobilization,   spinal   cord   realignment   and
stabilization,  and  decompression.  To date, there is no drug therapy available
for   SCIs   except    palliative    therapies    using   the    corticosteroid,
methylprednisolone,  to reduce  inflammation  of the injured area,  and standard
medical practice for complications arising from chronic denervation.

     We believe that the transplantation of porcine fetal spinal cord cells into
the site of injury of a damaged  human  spinal  cord may  partially  reestablish
neural pathways. The transplantation of these cells into a recently injured cord
may  prevent  secondary  neural  and  muscular  atrophy  known to occur in these
patients.  Partial or full  recovery of limb  movement,  and other motor  neural
pathways  may  reduce  the  overall  time spent in the  hospital,  decrease  the
secondary  equipment  required for care, and reduce severe and life  threatening
complications arising from the injury.

     The FDA has  cleared  our IND to  conduct a  six-patient  Phase 1  clinical
trial.  We hope to determine  from this trial whether  porcine fetal spinal cord
cells  transplanted  into the damaged spinal cord region will engraft and repair
the  damage,  leading  to  improved  mobility  and  function.  We plan to  begin
recruitment  of patients  at Albany  Medical  Center in Albany,  New York and at
Washington University Medical Center in St. Louis.

NeuroCell-HD for Huntington's Disease

     Huntington's disease is a genetically  transmitted disease caused by a loss
of neural cells in the  striatum,  a specific  region of the brain.  The loss of
these neural cells results in a progressive  deterioration  marked by discordant
movement,  intellectual  impairment and a spectrum of psychiatric and behavioral
disturbances.  The clinical  symptoms of Huntington's  disease  generally become
apparent between 40 and 50 years of age. There are  approximately  25,000 people
diagnosed with Huntington's disease in the United States.  Currently there is no
effective  therapy  for  Huntington's  disease.  Treatment  is  palliative  with
tranquilizers and anti-psychotic drugs being the only options.

     Our  approach  to  treating   this  disease   consists  of  producing   and
transplanting  NeuroCell-HD  to replace the function of neural cells  damaged by
Huntington's  disease.  Porcine fetal neural cells are isolated from the area of
the pig's brain which  develops into the striatum for  transplantation  into the
striatum of the human transplant recipient's brain.




     We have  treated  twelve  patients  in a Phase 1  clinical  trial  in which
NeuroCell-HD was transplanted unilaterally. The Huntington's disease patients in
the clinical  trial  tolerated the procedure well and the  preliminary  clinical
data suggest that the product is safe. Of the twelve patients in this trial, the
Huntington's  disease in some patients has not progressed,  while the disease in
most of the patients has  progressed  as measured by total  functional  capacity
scores.  Two of the patients  have died from the  continued  progression  of the
disease.  Because  Huntington's  disease  progresses  over an extended period of
time, we intend to follow these patients for at least the next twelve months. We
currently  have no plans to  conduct a Phase 2  clinical  trial  until we gather
additional data.

Human Liver Cells for Cirrhosis

     Cirrhosis  of the  liver  is a  common  affliction  in the  United  States,
affecting  an estimated  1.5 million  individuals  and leading to  approximately
50,000 deaths annually. In cirrhosis,  liver tissue is progressively lost due to
accumulation  of fibrous tissue and scarring,  and liver function is compromised
due to the degenerative  changes.  The most common causes of cirrhosis are viral
hepatitis B and C infections and alcoholic liver disease.  In the initial stages
of the disease,  the patient may experience jaundice and disorientation as liver
function decreases. As the disease progresses,  the patient will be hospitalized
with increasing central nervous system effects,  known as encephalopathy,  which
may lead to coma.  The  tremendous  reserve of liver tissue allows the continued
function of the organ,  despite  loss of up to 90% of the normal  complement  of
liver cells. In advanced cirrhosis, little normal liver tissue remains.

     The only effective therapy for advanced cirrhosis is liver transplantation.
However,  the United  Network of Organ Sharing has documented a national lack of
donor  livers for  transplantation,  resulting  in a waiting  period of over two
years for the average patient. Over 5,000 individuals await liver transplants in
the United States and about 4,000 liver  transplants  are performed per year for
all  indications.  Recently,  artificial  extra-corporeal  liver assist devices,
commonly  known as ELAD,  containing  porcine or human liver cells attached to a
dialysis  cartridge  have been used in an  attempt  to treat  liver  failure  in
advanced  cirrhosis.  Studies  to  date  suggest  that  ELAD  may  improve  some
biochemical  parameters such as ammonia levels but the devices have not resulted
in increased survival.  Human whole liver  transplantation has also been used in
both  acute and  chronic  liver  failure.  In pilot  clinical  trials by others,
transplantation  of liver  cells  into  either  the liver or the spleen has been
shown to be both safe and  potentially  effective in humans as a bridge to whole
liver transplantation.

     For chronic liver  disease,  we and others have shown in animal models that
liver cell  integration is possible when liver cells are injected into the liver
or into the  spleen.  The  spleen  appears to be the  preferred  site due to the
fibrosis  and loss of blood supply to the  cirrhotic  liver.  In animal  models,
transplantation of liver cells into the spleen is well described, and results in
populating parts of the spleen with functioning  liver cells that perform normal
liver functions.

     We have initiated a six-patient, Phase 1 clinical trial of human liver cell
transplantation for the treatment of cirrhosis in patients that have been listed
for  organ  transplantation  but are  likely  to wait at least  one year  before
receiving a transplant. We believe these patients may benefit from the growth of
transplanted  liver  cells in their  liver or spleen  leading to an  increase in
liver  function.  In  addition,  expansion  of the cells  may  allow  sufficient
improvement to render a liver transplant unnecessary,  unlike the case with ELAD
which  are used  only as a bridge to



transplantation.  As part of the clinical trial, conventional  immunosuppression
will be  compared to the use of our  immunomodulation  technology  to  determine
whether graft  protection is achieved by this technique.  We are conducting this
study in  collaboration  with  Massachusetts  General  Hospital  and New England
Medical  Center  and at the  University  of  Nebraska  Medical  Center in Omaha,
Nebraska.

Porcine Liver Cells for Acute Liver Failure

     Acute liver  failure is a severe  life-threatening  disease that can result
from alcohol consumption, viral infections, such as hepatitis B and C, and drugs
or toxins that damage the liver.  The clinical  spectrum of acute liver  disease
can vary from patients with severe liver failure to patients  without  symptoms.
The  mortality  from acute liver  failure can be as high as 70%,  with  patients
dying  from   associated   complications.   Acute  liver   failure   results  in
approximately 63,000 deaths annually in the United States.

     There is  currently  no therapy that is  beneficial  for all patients  with
acute  liver  failure.  The best  available  therapy  is liver  transplantation.
However,   many  patients  are  unable  to  qualify  as  candidates   for  liver
transplantation  due to  multi-organ  failure  or  active  alcohol  consumption.
Current  therapies  attempt  to  treat  complications  arising  from  the  acute
condition, such as swelling of the brain, infections, and circulatory collapse.

     Our  approach to the  treatment  of acute  liver  failure is to support the
patient by liver cell  transplantation  in order to provide liver function while
allowing the  patient's  own liver to recover.  In  extensive  studies in animal
models,  our scientists  have shown that porcine liver cells can be isolated and
infused into the  recipient  liver where they  continue to  function.  Long-term
survival  and  function of these  cells has been  demonstrated  in these  animal
models. We believe liver cell transplantation  could become a viable alternative
to whole liver  transplantation  for the  treatment of acute liver  disease.  We
believe this approach would be preferable to  transplantation  of a whole liver,
due to the  difficulty of obtaining  livers for  transplantation  as well as the
expense and invasiveness of the procedure.

     Porcine  liver  cells  will be  infused  into the  spleen or liver of these
patients by minimally  invasive  procedures,  thus avoiding a surgical procedure
for these  critically  ill  patients.  In  addition to the high level of quality
control that can be maintained over the production of porcine liver cells, these
cells also have the advantage of being resistant to infection by human hepatitis
B and C viruses. Since many of the patients enrolled in this study are likely to
carry these  viruses,  we believe the  resistance  of the porcine liver cells to
infection may provide a further  advantage over human liver  transplantation  in
which hepatitis B and C reinfect donor livers.

     The FDA has cleared our IND application for a six-patient, Phase 1 clinical
trial to test  transplantation of porcine liver cells for the treatment of acute
liver failure.  Patients enrolled in this trial will not be candidates for liver
transplantation.  We are currently  recruiting  patients for this clinical trial
which will be conducted at Massachusetts  General Hospital,  New England Medical
Center and University of Nebraska Medical Center.



Additional Liver Cell Applications

     Successful  delivery of liver cells to patients with alcoholic hepatitis or
cirrhosis may provide the  possibility of applying this  technology to a variety
of other diseases.  The preparation of the cells and their delivery by minimally
invasive  procedures  should  be the  same in most of these  applications,  thus
providing a platform that may be used in multiple applications.

     Additional applications include the use of liver cells for the treatment of
metabolic    diseases    resulting    from    genetic    mutations.     Familial
hypercholesterolemia  is a disease  caused by a defective  receptor gene for low
density lipoprotein,  commonly referred to as LDL, that leads to elevated levels
of  LDL   cholesterol   and   coronary   disease  at  an  early  age.   Familial
hypercholesterolemia  afflicts  approximately  500,000  patients  in the  United
States.  Currently  available drugs do not  sufficiently  lower  circulating LDL
cholesterol levels in approximately 20% of these patients,  who may thus benefit
from  liver   cell   transplantation.   Our   scientists   have  shown   through
transplantation  of liver cells into a rabbit model of this disease that porcine
liver cells provide the animal with  functional  receptors that reduce serum LDL
levels.  There  is a  range  of  additional  metabolic  disorders  that  may  be
candidates  for treatment by liver cell  transplantation.  Approximately  30,000
patients in the United States suffer from these metabolic disorders.

Human Muscle Cells for Cardiac Disease

     Coronary  heart disease is the leading cause of death in the United States,
responsible for  approximately  1 of every 5 deaths,  or  approximately  500,000
deaths each year.  According to the American Heart Association,  approximately 1
million  heart  attacks  occur  annually  in the United  States.  Of the 800,000
patients who survive,  approximately 200,000 will die within a year. The disease
is  caused  by  the  accumulation  of  plaque,  consisting  of  lipid  deposits,
macrophages and fibrous tissue,  on the walls of vessels  supplying blood to the
heart  muscle.  Rupture of unstable  plaques  exposes  substances  that  promote
platelet  aggregation  and clot  formation.  The clot is composed of  platelets,
blood  cells and  fibrin  that can block  one or more of the  coronary  vessels,
resulting in an  inadequate  supply of oxygen to the heart  muscle.  This highly
active muscle is quickly damaged and the lesions are irreversible  because heart
muscle cells are not capable of cell division.  The end result is an infarct,  a
damaged  area of heart  muscle in which scar tissue and  fibrosis  replace  dead
heart muscles, lowering the ability of the heart to contract and function.

     Treatments to prevent tissue damage after a heart attack include drugs that
break down fibrin clots and open up blocked  arteries.  These drugs have greatly
influenced  morbidity and  mortality,  but must be  administered  within a short
interval  after a heart  attack  to be  effective.  Even  with  current  medical
management,   over  one  third  of  acute  heart  attacks  are  fatal.   Cardiac
catheterization and angioplasty to dislodge the clot and open the blocked vessel
have proved  effective in restoring  blood flow, but cannot reverse  preexisting
tissue damage.

     Our  scientists  have isolated and expanded  muscle cells from human tissue
and are studying the use of these cells for  transplantation  into damaged heart
muscle.  We believe that patients  suffering from heart attacks would benefit if
these  muscle  cells could repair  their  damaged  hearts.  These cells would be
isolated  from a muscle  biopsy of a patient  who had  suffered a heart  attack,
thereby allowing transplantation of a patient's own muscle cells into his or her
heart,  which  would  avoid  any  rejection.  In  preclinical  studies,  we have
demonstrated  that muscle cells  integrate  into rodent heart muscle.  The cells
form stable grafts in a damaged heart.



     In August 2000,  we  initiated a  six-patient,  Phase 1 clinical  trial for
patients with damaged heart muscle at Temple University Hospital.

Porcine RPE Cells for Macular Degeneration

     Age related macular degeneration, commonly referred to as AMD, is a disease
of the  retina  characterized  by the  loss  of  vision  due to the  atrophy  of
photoreceptors  in the central  part of the retina.  This is the most  important
part of the eye for high  resolution  vision,  such as that used in reading  and
driving.  Macular degeneration is a common disease,  affecting 13 million people
in  the  United  States.  It  is  primarily  a  disease  of  the  elderly,  with
approximately  19% of 65-74 year olds and  approximately 37% of individuals over
75 having vision loss.  Approximately 85-90% of AMD patients have the "dry" form
of the disease in which the RPE cell layer degenerates  without new blood vessel
growth and 10-15% have the "wet" form.

     While laser surgery is available to treat the "wet" form of AMD,  there are
currently no  effective  therapies  for the "dry" form of AMD. In AMD,  abnormal
accumulation of metabolic  debris results from reduced activity of the RPE cells
and leads to gradual loss of photoreceptors.  The RPE cells become dysfunctional
and  metabolic  by-products  damage  photoreceptors,  thus  compromising  visual
acuity. As this layer of cells does not readily  replicate in the adult,  damage
to the RPE cells can be  irreversible  and lead to loss of  photoreceptors  with
associated decreased visual acuity.

     RPE cells lie beneath the  light-sensing  cells  responsible for vision and
provide  support for the retinal  photoreceptors.  Our approach is to repopulate
the  dysfunctional  RPE cell layer by transplanting  porcine RPE cells below the
retinal   photoreceptors.   This  therapeutic  approach  has  the  potential  to
reestablish function in the central part of the retina,  prevent further loss of
vision  and to  improve  visual  acuity in  patients  with the "dry" form of the
disease.  In patients  with the "wet" form of AMD, this therapy could be used in
conjunction with surgery.

     The idea of replacing  defective RPE cells by transplantation is attractive
because  of the key role RPE cells  play in  maintaining  the  integrity  of the
photoreceptors  and their lack of regenerative  capacity.  Human fetal RPE cells
have been successfully tested by others in preclinical studies and are currently
being  evaluated in clinical  trials.  Our approach is to use porcine  fetal RPE
cells. Our preclinical  studies have  demonstrated the efficacy of porcine fetal
RPE cells in  rescuing  the  photoreceptor  layer of the retina from damage that
results from  experimental  disruption of the RPE cell layer.  We will also test
our  proprietary   immunomodulation  technology  to  prevent  rejection  of  the
transplant.  Assuming successful  completion of preclinical  studies, we plan to
file an IND for a six-patient Phase 1 clinical trial in late 2001.

Genzyme Joint Venture

     In September  1996, we formed  Diacrin/Genzyme  LLC with  Genzyme,  a joint
venture to develop and commercialize  NeuroCell-PD and  NeuroCell-HD.  Under the
terms of the  agreement,  Genzyme has provided  100% of the first $10 million in
funding for the development and  commercialization  of these product  candidates
incurred  after October 1, 1996,  and has agreed to provide 75% of the following
$40 million in funding.  We agreed to provide the




remaining 25% of the  following $40 million in funding.  We will share all costs
incurred in excess of $50 million  equally with Genzyme.  We will also share any
profits of the joint venture equally with Genzyme.  The joint venture  agreement
provides that we and Genzyme will jointly develop  NeuroCell-PD and NeuroCell-HD
and that  Genzyme  will market and sell these  products on a cost  reimbursement
basis on behalf of the joint  venture.  As of  December  31,  2000,  Genzyme had
provided $29.7 million to the joint venture and we had provided $6.5 million.

     In connection with the joint venture agreement with Genzyme,  we granted to
the joint venture the exclusive, worldwide,  irrevocable (during the term of the
joint  venture  agreement),  royalty-free  right  and  license  to  develop  and
commercialize NeuroCell-PD and NeuroCell-HD under our existing patent rights and
technology.  The license we granted is limited to the  treatment of  Parkinson's
disease and  Huntington's  disease in humans using porcine  fetal cells.  In the
event that  either we or Genzyme  develop or acquire  additional  technology  or
patent rights that are useful in this field, the party owning such technology or
patent  rights is  obligated  to offer a license  to the joint  venture  to such
technology or patent rights.

     The joint venture is governed by a six-member  steering committee comprised
of three  persons from  Genzyme and three  persons  from  Diacrin.  The steering
committee  meets  regularly and makes all of the  decisions  with respect to the
joint venture's work plans and budgets.  The steering  committee has appointed a
program  manager  from each  organization  to execute  the agreed  upon  product
development work plans.

Manufacturing

     The  manufacture  of most  of our  products  will  require  the  continuous
availability of porcine tissue  harvested under cGMP from pigs tested to be free
of  infectious  agents.  Our current  source of pig  facilities  and services is
obtained under contracts from Tufts University School of Veterinary Medicine and
PharmServices, Inc., a division of Charles River Laboratories, Inc. We have also
qualified several pig producers to provide pigs for our production processes.

     For the Phase 1 clinical  trials of our  products,  we isolate  and prepare
cell  populations  in our own clinical  production  facilities  in  Charlestown,
Massachusetts.  We expanded our manufacturing  capacity to include approximately
12,000  square feet of clinical  production  and  support  space in  Framingham,
Massachusetts  dedicated to the production of our joint venture  products needed
in  conjunction  with planned  clinical  trials.  We believe that the Framingham
facility  is capable  of  satisfying  projected  initial  demand for  commercial
quantities  of  NeuroCell-PD.  This will  enable us to utilize  our  Charlestown
facility for the clinical supply of other product candidates and to postpone the
need for significant additional investment in such facilities.

     We currently  obtain the antibody  fragments  used in our  immunomodulation
technology  from a contract  manufacturer.  We will evaluate on an ongoing basis
the cost effectiveness and other relevant factors necessary to determine whether
we should continue to obtain the antibody fragment from a contract  manufacturer
or produce them ourselves.

     Our long-range plan is to expand our internal  manufacturing  capabilities,
including  the  facilities  necessary  to test,  isolate and package an adequate
supply of finished  cell  products in order to meet our  long-term  clinical and
commercial manufacturing needs.



Patents and Licenses

     We intend to  aggressively  seek  patent  protection  for any  products  we
develop.  We also intend to seek patent protection or rely upon trade secrets to
protect  certain  of our  technologies  which  will be used in  discovering  and
evaluating  new  products.  We  have  11  issued  U.S.  patents  and  24  patent
applications pending with the United States Patent and Trademark Office. We have
also  filed  foreign  counterparts  in the  European  Union and  other  selected
countries.  These applications seek composition-of-matter and use protection for
the various products we have in development.

     Massachusetts  General  Hospital has been awarded two patents in the United
States  covering  the  basic   immunomodulation   technology  we  use.   Foreign
counterparts  of these  patents have been filed in the European  Union and other
selected countries. Under an agreement with MGH, we have an exclusive, worldwide
license to the technology and the inventions  described in the patents,  and all
foreign counterparts, including any continuations,  reissues or substitutions as
well as any patents and equivalents which may mature from such patents,  subject
to the payment of royalties. Unless sooner terminated, our rights will continue,
on a country by country  basis,  until the last to expire of the patents.  We or
MGH may  terminate  the  agreement,  upon  notice,  in the event the other party
defaults in its material  obligations and has failed to cure this default within
60 days of receipt of this notice.

     To protect our trade secrets and other proprietary information,  we require
all  employees,   consultants,   advisors  and   collaborators   to  enter  into
confidentiality agreements with us.

Sales and Marketing

     Our joint venture agreement with Genzyme authorizes  Genzyme,  which has an
established   sales   force   experienced   in  the  sales  and   marketing   of
biopharmaceutical  and surgical  products,  to market and sell  NeuroCell-PD and
NeuroCell-HD  on an  exclusive  basis as agent of the  joint  venture  on a cost
reimbursement basis.

     We have not yet developed  sales and marketing  capabilities  for our other
product   candidates.   We  may  form  strategic   alliances  with   established
pharmaceutical or biotechnology companies in order to finance the development of
certain of our products and,  assuming  successful  development,  to market such
products.  These  alliances  may enable us to expand or  accelerate  our product
development efforts and also may provide us with access to established marketing
organizations.  Alternatively,  we may decide to market some of our  products on
our own.

Government Regulation

     Regulation by governmental  authorities in the United States,  the European
Union member states and other foreign  countries is a significant  factor in the
development,  manufacture  and  marketing of our product  candidates  and in our
ongoing research and product  development  activities.  All of our products will
require regulatory approval by governmental agencies prior to commercialization.
In particular,  human  therapeutic  products are subject to rigorous testing and
approval  procedures by the FDA and similar  authorities  in foreign  countries.
Various  statutes and regulations  govern the preclinical and clinical  testing,
manufacturing,  labeling, distribution,  advertising and sale of these products.
The process of obtaining  these  approvals and the  subsequent  compliance  with
applicable  statutes and regulations require the expenditure of substantial time
and financial and other resources.



     Preclinical  testing is generally conducted in the laboratory on animals to
evaluate  the  potential  efficacy  and the safety of a  product.  In the United
States the results of these  studies are  submitted to the FDA as part of an IND
application,  which must receive FDA clearance before human clinical testing can
begin.  Clinical  trials  are  typically  conducted  in three  phases  which may
overlap.  Generally,  in phase 1,  clinical  trials are  conducted  with a small
number of human  subjects to  determine  the early safety  profile.  In Phase 2,
clinical  trials  are  conducted  with  groups of  patients  afflicted  with the
specific disease in order to determine preliminary  efficacy,  optimal treatment
regimens and expanded evidence of safety.  Where a product candidate is found to
have an effect at an optimal dose and to have an  acceptable  safety  profile in
Phase 2, larger  scale,  multi-center,  randomized  and blinded Phase 3 clinical
trials are conducted with patients  afflicted with the target disease to further
test for  safety,  to  further  evaluate  clinical  effectiveness  and to obtain
additional   information  for  labeling.  In  addition,   the  FDA  may  request
post-marketing  (Phase 4)  monitoring  of the  approved  product,  during  which
clinical  data  are  collected  on  selected   groups  of  patients  to  monitor
longer-term safety.

     Upon completion of Phase 3, for products  regulated by the FDA's Center for
Biologic  Evaluation and Research,  commonly referred to as CBER, the results of
preclinical  and  clinical  testing  are  submitted  to the FDA in the form of a
Biologics  License  Application,  commonly  referred to as BLA,  for approval to
manufacture and commence  commercial sales. In responding to these applications,
the FDA may grant marketing approval, request additional information or deny the
application if it determined that the application  does not satisfy the agency's
regulatory approval criteria. We expect that CBER will regulate NeuroCell-PD and
all of our other products.

     The nature of the marketing claims we will be permitted to use for labeling
and advertising  will be limited to those allowed in the FDA's approval.  Claims
beyond those approved would  constitute a violation of the Food, Drug & Cosmetic
Act or the FD&C Act. Noncompliance with the provisions of the FD&C Act or Public
Health  Service  Act can  result  in,  among  other  things,  loss of  approval,
voluntary or mandatory product recall, seizure of products,  fines,  injunctions
and civil or crimial penalties. Our advertising is also subject to regulation by
the Federal Trade  Commission  under the FTC Act, which prohibits unfair methods
of  competition  and  unfair or  deceptive  acts or  practices  in or  affecting
commerce.  Violation can result in a variety of  enforcement  actions  including
fines, injunctions and other remedies.

     In the European member states and other foreign  countries,  our ability to
market a product is contingent upon receiving  marketing  authorization from the
appropriate  regulatory  authorities.  The requirements governing the conduct of
clinical trials, marketing authorization,  pricing and reimbursement vary widely
from  country to country.  Generally,  we intend to apply for foreign  marketing
authorizations  at  a  national  level.  However,  within  the  European  Union,
procedures are available to companies  wishing to market a product in one or all
European Union member states.  This centralized process is conducted through the
European Medicines  Evaluation  Agency,  known as the EMEA. The EMEA coordinates
the  regulatory  process,  while a body of  experts  drawn  from  member  states
undertakes  the scientific  assessment of the product and  recommends  whether a
product satisfies the criteria of safety,  quality and efficacy for approval. If
the  authorities  are satisfied  that adequate  evidence of safety,  quality and
efficacy has been presented,  a marketing  authorization  will be granted.  This
foreign  regulatory  approval  process includes all of the risks associated with
FDA  approval set forth  above.  We may rely on  licensees to obtain  regulatory
approval for marketing  certain of our products in certain European Union member
states or other foreign countries.



     We are also subject to various federal,  state and local laws,  regulations
and  recommendations  relating  to  safe  working  conditions,   laboratory  and
manufacturing  practices,  the  experimental  use of  animals  and  the  use and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds,  infectious  disease  agents and  recombinant  DNA materials  used in
connection with our research work.

     We intend to take  advantage of the  regulatory  pathways which may provide
expedited  review of our cell  transplantation  products and allow  limited cost
recovery during the clinical research phase. These include: (1) expedited review
for more  effective  or  better  tolerated  therapies  for  serious  conditions,
commonly  referred to as fast track  designation,  and (2) seeking  approval for
limited cost recovery  during clinical  testing under  treatment IND status.  We
also intend to seek marketing  exclusivity for products which qualify for orphan
drug status, where appropriate.

     Fast  Track  Designation.  In  1997,  Congress  enacted  the  Food and Drug
Administration  Modernization  Act, in part, to ensure the  availability of safe
and effective drugs by expediting the FDA review process for new products.  This
act establishes a statutory  program for the approval of fast track products.  A
fast track  product is defined as a new drug  intended  for the  treatment  of a
serious or  life-threatening  condition,  which  demonstrates  the  potential to
address unmet medical needs. Under the fast track program,  the sponsor of a new
drug may request the FDA to  designate  the drug as a fast track  product at the
time of the IND  submission or after.  If a  preliminary  review of the clinical
data suggests  that a fast track product may be effective,  the FDA may initiate
review of sections of a marketing  application  for a fast track product  before
the sponsor  completes  the  application.  NeuroCell-PD  was granted  fast track
designation in 1999.

     Treatment IND. Treatment IND is a mechanism  established by the FDA in 1987
which  allows a company to  distribute  promising  investigational  therapies to
patients  outside of the established  clinical trials and to charge a reasonable
fee for such therapy.  The disease must be serious or life-threatening and there
must not be satisfactory  alternative treatments.  Treatment IND status has been
applied to a variety of diseases including cancer,  AIDS,  Parkinson's  disease,
Alzheimer's  disease and multiple sclerosis and to several  anti-infectives  for
renal  transplant  patients.  We  intend  to  pursue  this  designation,   where
appropriate.

     Orphan Drug Status.  The Orphan Drug Act generally  provides  incentives to
manufacturers  to  undertake  development  and  marketing  of  products to treat
relatively  rare  diseases or diseases  where fewer than 200,000  persons in the
United  States would be likely to receive the  treatment.  A drug that  receives
orphan  drug  designation  by the FDA and is the first  product to  receive  FDA
marketing  approval for its product claim is entitled to a seven-year  exclusive
marketing  period in the  United  States  for that  product  claim.  The FDA may
terminate  an  orphan  drug  designation  for  many  reasons,  including  if the
manufacturer of the orphan drug product cannot provide an adequate supply of the
product.  Furthermore,  a drug that the FDA  considers  to be  different  from a
particular  orphan drug is not barred from sale in the United States during such
seven-year  exclusive  marketing  period.  Legislation  to limit  the  marketing
exclusivity  provided for certain orphan drugs has occasionally  been introduced
in  Congress.  Although the outcome of that  legislation  is  uncertain,  future
legislation  may limit the  incentives  currently  afforded to the developers of
orphan drugs.



     We have  assigned  to the joint  venture  the orphan  drug  designation  we
received from the FDA for NeuroCell-PD and for  NeuroCell-HD.  Our porcine fetal
spinal  cord  cells  for  spinal  cord  injury  product  is also  targeted  to a
population  of less than  200,000  and,  therefore,  we will pursue  orphan drug
designation for this product candidate.

Competition

     We believe  that our ability to compete  successfully  will be based on our
ability to create  and  maintain  scientifically  advanced  technology,  develop
proprietary products and attract and retain qualified scientific  personnel.  In
addition, we have to obtain adequate financing, patents, orphan drug designation
or other protection for our products, and required regulatory approvals,  and to
manufacture and successfully  market our products both independently and through
collaborators.

     The  biopharmaceutical  and pharmaceutical  industries are characterized by
intense competition.  We compete against numerous companies,  many of which have
substantially  greater  financial and other  resources  than we do.  Private and
public academic and research  institutions  also compete with us in the research
and  development  of  human  therapeutic  products.  In  addition,  many  of our
competitors have  significantly  greater experience than we do in the testing of
pharmaceutical  and  other  therapeutic  products  and  obtaining  FDA and other
regulatory  approvals  of  products  for use in health  care.  Accordingly,  our
competitors may succeed in obtaining FDA approval for products more rapidly than
we do. If we commence significant commercial sales of our products, we will also
be  competing   with  respect  to   manufacturing   efficiency   and   marketing
capabilities, areas in which we have limited or no experience.

     Our products  under  development  will compete with  products and therapies
which are either currently available or currently under development. Competition
will be based,  among other things,  on efficacy,  safety,  reliability,  price,
availability  of  reimbursement  and  patent  position.  We are  aware  of other
companies which are pursuing research and development of alternative products or
technologies addressing the same disease categories as our development programs.

Employees

     As of February 28, 2001,  we had 38  full-time  employees,  30 of whom were
engaged in research, development, clinical and quality assurance/quality control
activities. None of our employees are represented by a labor union or covered by
a collective bargaining agreement.

Item 2.  Properties

     We lease a facility  which  contains  approximately  28,000  square feet of
space in  Charlestown,  Massachusetts.  The lease had a ten-year  term ending in
2001, providing for a base rental rate of approximately  $60,000 per month, plus
applicable property taxes and insurance. In October 2000, we exercised the first
of two options we have,  each to extend the lease an additional five years. As a
result, our lease currently expires in 2006. The new base rental rate which will
begin in October 2001 will be determined in accordance  with our lease agreement
which calls for us to pay 90% of the market  value rate for similar  space.  Our
facilities are equipped with laboratory




and cell culture capabilities sufficient to satisfy our research and development
requirements  for  the  foreseeable  future  and  cell  isolation   capabilities
sufficient  to satisfy the clinical  production  requirements  of several of our
product  candidates.  To the extent that  additional  similar  facilities may be
required,  we will be required to secure  additional  facilities or seek outside
contractors to provide such capabilities.

Item 3.  Legal Proceedings

     We are currently not a party to any material legal proceedings.

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

     No  matters  were  submitted  to a vote of our  security  holders,  through
solicitation of proxies or otherwise, during the last quarter of the fiscal year
ended December 31, 2000.

     In connection  with our initial public offering in February 1996, we issued
2,875,000  redeemable warrants to purchase our common stock at an exercise price
of $16 per share,  subject to certain  adjustments.  The warrants were traded on
the NASDAQ  National  Market under the symbol DCRNW.  On December 31, 2000,  all
unexercised warrants expired.

     As of February 20, 2001 there were  approximately 110 record holders of our
common stock and approximately 3,900 beneficial owners of our common stock.

     We have never  declared or paid cash  dividends  on our capital  stock.  We
intend to retain earnings, if any, for use in our business and do not anticipate
declaring or paying any cash dividends in the foreseeable future.

     We did not sell any equity securities during the quarter ended December 31,
2000 that were not registered under the Securities Act.



     The following information updates and supplements the information regarding
use of proceeds  originally filed by Diacrin on Form SR for the period ended May
12,  1996,  as amended to date and  relates to  securities  sold by the  Company
pursuant to the Registration  Statement on Form S-2  (Registration No: 33-80773)
which was declared effective on February 12, 1996: Through December 31, 2000, we
have used  approximately  $18,400,000 of the total net proceeds from our initial
public offering of $20,911,755.  Of the $18,400,000 used, approximately $394,000
was used for the purchase of machinery and equipment; approximately $1.0 million
was used for repayment of indebtedness;  and approximately  $17,006,000 was used
for working  capital.  The unused  proceeds of  approximately  $2,512,000 are in
temporary  investments  consisting of corporate  notes and a money market mutual
fund. All proceeds used or invested were direct or indirect payments to others.

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

Overview

     Since our inception,  we have principally focused our efforts and resources
on research and  development  of cell  transplantation  technology  for treating
human diseases that are  characterized by cell dysfunction or cell death and for
which current therapies are either inadequate or nonexistent. Our primary source
of working  capital to fund those  activities has been proceeds from the sale of
equity and debt securities. In addition, since October 1, 1996, we have received
funding from our joint venture with Genzyme in support of the  NeuroCell-PD  and
NeuroCell-HD  product  development  programs.  We have not received any revenues
from the sale of products to date and do not expect to generate product revenues
for the next several years. We have  experienced  fluctuating  operating  losses
since  inception and expect that the additional  activities  required to develop
and  commercialize  our products will result in increasing  operating losses for
the next several years.  At December 31, 2000, we had an accumulated  deficit of
$47.8 million.



     In September  1996,  we formed a joint  venture with Genzyme to develop and
commercialize  NeuroCell-PD and NeuroCell-HD.  Under the joint venture agreement
Genzyme  agreed  to fund  100% of the  first  $10  million  of  development  and
commercialization  costs  incurred  after  October 1, 1996,  75% of the next $40
million and 50% of all development and commercialization  costs in excess of $50
million.  After  Genzyme  funds the first $10 million,  we are  responsible  for
funding  25%  of  the  next  $40  million  and  50%  of  all   development   and
commercialization costs in excess of $50 million.

     Through   December  31,   1997,   Genzyme  made  100%  of  the  total  cash
contributions  to the joint venture.  During the first quarter of 1998, we began
making  cash  contributions  to the  joint  venture  equal  to 25% of the  joint
venture's funding  requirements.  As of December 31, 2000,  approximately  $29.7
million had been  contributed to the joint venture by Genzyme and  approximately
$6.5  million  had been  contributed  by us. The joint  venture's  2001  product
development plans, together with our continued funding of the joint venture, are
expected  to  significantly  increase  our net  loss  and  our  use of cash  and
investments to fund the joint venture in 2001 as compared with 2000.

     We record  as  research  and  development  expense  all  costs  related  to
NeuroCell-PD and NeuroCell-HD  incurred by us on behalf of the joint venture. We
then  recognize  research  and  development  revenue  equal  to  the  amount  of
reimbursement  received by us from the joint venture out of funds contributed by
Genzyme.  We do not recognize  research and  development  revenue for amounts we
receive from the joint venture out of funds contributed by us. As Genzyme incurs
costs on behalf of the joint venture that we are obligated to fund, we recognize
an expense in our  statement of  operations  captioned  "Equity in operations of
joint venture."

Results of Operations

Year Ended December 31, 2000 Versus Year Ended December 31, 1999

     Research and development  revenues were  approximately $2.1 million for the
year ended  December 31, 2000 and $3.0  million for the year ended  December 31,
1999.  Revenues for both years were comprised entirely of revenue from the joint
venture.  The  decrease  in  revenues  was  primarily  a result of a decrease in
clinical  production  activity  related to our joint venture with  Genzyme.  The
joint venture completed  accruing patients into its Phase 2/3 clinical trial for
NeuroCell-PD in 1999.

     Interest  income was $3.1  million  for the year ended  December  31,  2000
versus $1.3 million for the year ended  December 31, 1999.  The increase in 2000
was due to greater cash balances  available  for  investment in the current year
period as a result of our public stock offering completed in March 2000.



     Research  and  development  expenses  of $6.0  million  for the year  ended
December  31,  2000 and $5.9  million  for the year  ended  December  31,  1999,
remained relatively unchanged between the periods.

     General  and  administrative  expenses  of $1.3  million for the year ended
December  31,  2000 and $1.4  million  for the year  ended  December  31,  1999,
remained relatively unchanged between the periods.

     Interest  expense  was  $30,000  for the year ended  December  31, 2000 and
$47,000 for the year ended  December 31,  1999.  The decrease in 2000 was due to
the scheduled pay down of lease and loan debt outstanding.

     For the year ended  December  31, 2000,  we recorded a $1.4 million  charge
related to our equity in the operations of the joint venture  compared to a $1.7
million  charge for the year ended  December 31, 1999.  This expense  related to
funds  contributed  by us to the joint  venture that were used to fund  expenses
incurred by Genzyme on behalf of the joint venture.  The decreased charge in the
current  year  period was  primarily  due to a  decrease  in  clinical  activity
performed  by  Genzyme  on  behalf  of the joint  venture  as the joint  venture
completed recruiting patients into it Phase 2/3 clinical trial in 1999.

     We  incurred a net loss of  approximately  $3.5  million for the year ended
December 31, 2000 versus a net loss of  approximately  $4.8 million for the year
ended December 31, 1999.

Year Ended December 31, 1999 Versus Year Ended December 31, 1998

     Research and development  revenues were  approximately $3.0 million for the
year ended December 31, 1999 versus $3.6 million for the year ended December 31,
1998.  Revenues for both years were comprised  entirely of revenue received from
Genzyme for  reimbursement of our expenses for the joint venture.  The reduction
in research and development  revenues in 1999 was primarily  attributable to the
reduction  from 100% to 75% of the  percentage  of funding for the joint venture
provided by Genzyme. This reduction took effect in the first quarter of 1998.

     Interest  income was $1.3  million  for the year ended  December  31,  1999
versus $1.6 million for the year ended  December  31, 1998.  The 16% decrease in
1999 was  primarily  due to  reduced  interest  income  realized  on lower  cash
balances available for investment.

     Research  and  development  expenses  were $5.9  million for the year ended
December 31, 1999 versus $7.4 million for the year ended  December 31, 1998. The
20% decrease in 1999 was primarily due to a reduction in preclinical research as
several of our product candidates had begun clinical testing.  The decrease was,
to a lesser  extent,  due to the additional  production  costs of clinical grade
antibody  incurred  during 1998 for use in our clinical  trials and  preclinical
research.

     General and  administrative  expenses  were $1.4 million for the year ended
December 31, 1999 and $1.5 million for the year ended December 31, 1998.



     Interest  expense  was  $47,000  for the year ended  December  31, 1999 and
$89,000 for the year ended  December 31,  1998.  The decrease in 1999 was due to
the scheduled pay down of lease and loan debt outstanding.

     We recorded a charge of $1.7  million for the year ended  December 31, 1999
and $1.1  million for the year ended  December 31, 1998 related to our equity in
the operations of the joint venture.  The increased  charge was primarily due to
the timing of the reduction in the  percentage of funding from Genzyme from 100%
to 75% in accordance with the joint venture agreement.

     We incurred a net loss of  approximately  $4.8  million for each of the two
years in the period ended December 31, 1999.

Liquidity and Capital Resources

     We have financed our  activities  primarily  with the net proceeds from the
sale of equity and debt securities  aggregating $102.0 million and with interest
earned thereon.  In addition,  we have recorded  approximately  $14.5 million in
revenue  from our joint  venture  since it  commenced  on October  1,  1996.  At
December 31, 2000, we had cash and cash equivalents,  short-term investments and
long-term investments aggregating approximately $54.6 million.

     Net cash used in operating  activities  was $2.5 million for the year ended
December  31, 2000,  $2.9 million for the year ended  December 31, 1999 and $3.1
million for the year ended  December 31, 1998.  Cash used in operations  for the
years ended December 31, 2000,  1999 and 1998 was primarily  attributable to our
net loss, offset in part by our equity in operations of the joint venture.

     Net cash used in investing  activities was $25.6 million for the year ended
December 31, 2000.  Net cash provided by investing  activities  was $344,000 for
the year ended  December 31, 1999.  Net cash used in investment  activities  was
$6.0 million for the year ended  December  31, 1998.  Net cash used in investing
activities for the year ended December 31, 2000, was primarily  attributable  to
an increase in short-term investments and long-term investments. The increase in
investments  was due to our public  offering of Common Stock in March 2000.  Net
cash provided by investing  activities  for the year ended December 31, 1999 was
primarily attributable to a decrease in short-term investments and the return of
capital for services provided on behalf of our joint venture,  offset in part by
our investment in our joint venture.  Net cash used by investing  activities for
the year ended  December 31, 1998 was primarily  attributable  to an increase in
short-term  investments and our investment in our joint venture,  offset in part
by a decrease  in  long-term  investments  and to a lesser  extent the return of
capital for services provided on behalf of our joint venture.

     Net cash  provided by financing  activities  was $37.0 million for the year
ended December 31, 2000. Net cash used in financing  activities was $220,000 for
the year ended December 31, 1999. Net cash provided by financing  activities was
$9.1  million  for the year  ended  December  31,  1998.  Net cash  provided  by
financing  activities  for the  year  ended  December  31,  2000  was  primarily
attributable  to net proceeds from the sale of common stock in a public offering
in March 2000. Net cash used in financing activities for the year ended December
31, 1999 was primarily attributable to principal payments made towards long-term
debt. Net cash provided by financing  activities for the year ended December 31,
1998 was primarily attributable to net proceeds from the sale of common stock in
a private placement in February 1998.



     We have purchased  approximately  $2.4 million of capital  equipment  since
inception.  In November  1997, we borrowed  $650,000 at the prime rate plus 0.5%
(10.00% at December 31, 2000) under an unsecured five-year term loan with a bank
to finance our biomedical  animal facility  acquired during 1997. As of December
31, 2000, we owed $249,000 under this term loan. We had no material  commitments
for capital expenditures as of December 31, 2000.

     In accordance  with the joint  venture  agreement,  Genzyme  agreed to make
financing  available  to us from and after the date that  Genzyme  provides  the
initial  $10  million of funding to the joint  venture.  Genzyme  agreed to make
available an unsecured, subordinated line of credit of up to an aggregate amount
of $10 million. We may draw on this facility only in the event that our cash and
cash  equivalents  are  insufficient  to  fund  our  budgeted  operations  for a
specified  period  of  time,  and we may use  the  funds  only  to fund  capital
contributions to the joint venture.  The facility will be available  through the
date  five  years  after  the  date  we  first  draw  on the  facility,  and all
outstanding  principal  and  interest  will  be due on that  fifth  anniversary.
Advances will be interest-bearing, evidenced by a promissory note and subject to
other customary conditions.  The aggregate amount of draws under the facility in
any calendar  year may not exceed $5 million.  We have not made any draws on the
facility as of December 31, 2000, and do not anticipate  drawing on the facility
for the foreseeable future.

     We believe that our existing  funds,  together with expected future funding
under the joint venture  agreement with Genzyme,  will be sufficient to fund our
operating  expenses  and  capital  requirements  as  currently  planned  for the
foreseeable  future.  However,  our cash  requirements  may vary materially from
those now planned because of results of research and development,  the scope and
results of  preclinical  and  clinical  testing,  any  termination  of the joint
venture,  relationships with future strategic partners, changes in the focus and
direction  of  our   research  and   development   programs,   competitive   and
technological  advances,  the FDA's regulatory process, the market acceptance of
any approved products and other factors.

     We expect to incur substantial additional costs, including costs related to
ongoing  research and  development  activities,  preclinical  studies,  clinical
trials,  expanding  our cell  production  capabilities  and the expansion of our
laboratory  and  administrative  activities.  Therefore,  in  order  to  achieve
commercialization of our potential products, we may need substantial  additional
funds.  We  cannot  assure  you that we will be able to  obtain  the  additional
funding that we may require on acceptable terms, if at all.

Diacrin/Genzyme LLC Financial Statements

change. However, while we may elect to update these forward-looking  statements,
we specifically disclaim any obligation to do so. See "Cautionary Note Regarding
Forward-Looking Statements."

Risks Related to Our Business, Industry and Strategy

     We have not successfully  commercialized any products to date and, if we do
not successfully commercialize any products, we will not be profitable

     Neither we nor any other company has received regulatory approval to market
the types of products we are  developing.  The products  that we are  developing
will require additional research and development, clinical trials and regulatory
approval  prior to any  commercial  sale.  Other than our  NeuroCell-PD  product
candidate  for the  treatment  of  Parkinson's  disease  which is in  Phase  2/3
clinical trials,  the remainder of our product candidates are currently in early
phase clinical trials or in the preclinical  stage of development.  Our products
may not be effective  in treating any of our targeted  disorders or may prove to
have undesirable or unintended side effects, toxicities or other characteristics
that may prevent or limit their commercial use.

     We  currently  have no  products  for  sale and do not  expect  to have any
products  available  for sale for several  years.  If we are not  successful  in
developing and commercializing any products, we will never become profitable.

     We are  dependent on Genzyme  Corporation  to fund,  develop and market our
lead  product  candidate,  NeuroCell-PD,  and if our joint  venture with Genzyme
terminates,  we may not be able to complete  development or commercialization of
NeuroCell-PD



     We have entered into a joint venture agreement with Genzyme relating to the
development and  commercialization  of  NeuroCell-PD,  our most advanced product
candidate. This agreement also covers our NeuroCell-HD product candidate.  Under
this  agreement,  Genzyme has agreed to provide  significant  funding toward the
development and  commercialization  of these products and to market and sell the
products on behalf of the joint venture.  Genzyme has the right to terminate the
agreement  at any time upon 180 days  notice to us.  We cannot  assure  you that
Genzyme  will not  terminate  this  agreement,  or that our  economic  and other
interests  will coincide with those of Genzyme during the term of the agreement.
If Genzyme were to terminate this agreement, we:

     - would lose a significant source of funding for the NeuroCell-PD and
       NeuroCell-HD product development programs;

     - would lose access to Genzyme's experienced development, sales and
       marketing organizations and manufacturing facilities;

     - would need to establish clinical production facilities for the production
       of NeuroCell-PD and NeuroCell-HD; and

     - may be unable to complete development or commercialization of
       NeuroCell-PD and NeuroCell-HD.

     In addition, Genzyme has the right to terminate the joint venture agreement
following an  unremedied  breach of any material term of the agreement by us. If
Genzyme terminates the agreement, Genzyme has the option to obtain an exclusive,
worldwide,  royalty bearing license to some of our technology  which is required
to manufacture and market  NeuroCell-PD and  NeuroCell-HD.  If Genzyme exercises
this option,  we would only be entitled to receive a royalty on the net sales of
NeuroCell-PD and NeuroCell-HD and this royalty would be significantly  less than
the amounts we would be entitled to receive under the joint venture agreement.

     Our cell  transplantation  technology  is  complex  and novel and there are
uncertainties as to its effectiveness

     We have  concentrated our efforts and therapeutic  product research on cell
transplantation  technology,  and our future  success  depends on the successful
development  of  this   technology.   Our  principal   approach  is  based  upon
xenotransplantation, or the transplantation of cells, tissues or organs from one
species to another. Our product candidates generally involve the transplantation
of porcine  (pig) neural cells into humans.  Xenotransplantation  is an emerging
technology  with limited  clinical  experience.  Neither the FDA nor any foreign
regulatory body has approved any  xenotransplantation-based  therapeutic product
for humans.

     Our technological  approaches may not enable us to successfully develop and
commercialize  any products.  If our  approaches are not  successful,  we may be
required  to  change  the  scope  and  direction  of  our  product   development
activities.  In  that  case,  we may  not be  able  to  identify  and  implement
successfully an alternative product development strategy.

     Xenotransplantation  involves  risks which have resulted in additional  FDA
oversight and which in the future may result in additional regulation



     Xenotransplantation poses a risk that viruses or other animal pathogens may
be  unintentionally  transmitted  to a human  patient.  The FDA  requires  us to
perform  tests to determine  whether  infectious  agents,  including  PERV,  are
present in patients who have  received  porcine  cells.  While PERV has not been
shown to cause any disease in pigs,  it is not known what effect,  if any,  PERV
may have on humans.  We have  performed  tests on patients who have received our
porcine cells.  No PERV has been detected to date, but we cannot assure you that
we will not detect PERV or another infectuous agent in the future.

     The FDA requires lifelong monitoring of porcine cell transplant recipients.
If PERV or any other virus or infectious  agent is detected in tests or samples,
the FDA may require us to halt our clinical trials and perform  additional tests
to assess the risk to patients of  infection.  This could  result in  additional
costs to us and delays in the trials of our porcine cell products.  Furthermore,
even if patients who have received our porcine cells remain PERV-free,  we could
be adversely  affected if PERV is detected in patients who receive porcine cells
provided by others.

     In  January  2001,  the FDA issued  definitive  regulatory  guidelines  for
xenotransplantation  titled  "PHS  Guideline  on  Infectious  Disease  Issues in
Xenotransplantation."  We cannot  assure you that we will be able to comply with
these guidelines.

     We face substantial  competition,  which may result in others  discovering,
developing or commercializing products before or more successfully than we do

     The products we are developing compete with existing and new products being
developed by pharmaceutical,  biopharmaceutical and biotechnology  companies, as
well as universities  and other research  institutions.  Many of our competitors
are  substantially  larger than we are and have  substantially  greater  capital
resources,  research and development staffs and facilities than we have. Efforts
by other  biotechnology  or  pharmaceutical  companies could render our products
uneconomical  or result in therapies for the disorders we are targeting that are
superior to any therapy we develop.  Furthermore,  many of our  competitors  are
more  experienced  in  product  development  and  commercialization,   obtaining
regulatory  approvals and product  manufacturing.  As a result, they may develop
competing  products  more  rapidly and at a lower cost.  These  competitors  may
discover,  develop and commercialize  products which render  non-competitive  or
obsolete the products that we are seeking to develop and commercialize.

     If the market is not  receptive  to our  products  upon  introduction,  our
products may not achieve commercial success

     The  commercial  success  of any of our  products  will  depend  upon their
acceptance by patients,  the medical community and third-party payors. Among the
factors that we believe will materially affect acceptance of our products are:

     - the timing of receipt of marketing approvals and the countries in which
       those approvals are obtained;

     - the safety and efficacy of our products;

     - the need for surgical administration of our products;

     - problems encountered in the field of xenotransplantation;



     - the success of physician education programs;

     - the  cost  of  our  products  which  may  be  higher  than   conventional
       therapeutic    products    because   our   products    involve   surgical
       transplantation of living cells; and

     - the availability of government and third-party payor reimbursement of our
       products.

Risks Relating to Clinical and Regulatory Matters

     The  evaluation of the unblinded  data from our Phase 2/3 clinical trial of
NeuroCell-PD may not support further development

     We have  completed  treatment  of  patients  in a Phase  2/3  trial for our
NeuroCell-PD  product candidate,  and the final patient in the trial reached the
eighteen-month  post-transplantation  endpoint  in February  2001.  The trial is
expected to be unblinded  in March 2001.  As is the case with the results of any
clinical  trial,  the  results  of the Phase 2/3  clinical  trial may not show a
statistically  significant  difference  between  the  treated  patients  and the
patients in the control group.  If such an outcome were to occur, it is possible
that further  clinical  development  of  NeuroCell-PD  would not be supported by
Genzyme, or that we may choose to discontinue development or modify the clinical
trial protocols, which could result in the termination of or significantly delay
the progress of the NeuroCell-PD development program.

     If our clinical  trials are not successful  for any reason,  we will not be
able to develop and commercialize any related products

     In order to obtain  regulatory  approvals  for the  commercial  sale of our
product candidates, we will be required to complete extensive clinical trials in
humans to demonstrate  the safety and efficacy of the products.  We have limited
experience in conducting clinical trials.

     The  submission of an IND may not result in FDA  authorization  to commence
clinical  trials.  If  clinical  trials  begin,  we  may  not  complete  testing
successfully  within any specific time period, if at all, with respect to any of
our product candidates.  Furthermore,  we or the FDA may suspend clinical trials
at any time on various grounds,  including a finding that the patients are being
exposed to unacceptable  health risks.  Clinical trials,  if completed,  may not
show any  potential  product to be safe or  effective.  Thus,  the FDA and other
regulatory  authorities  may not approve any of our product  candidates  for any
disease indication.

     The rate of completion of clinical  trials depends in part upon the rate of
enrollment  of  patients.  Patient  enrollment  is a function  of many  factors,
including  the size of the  patient  population,  the  proximity  of patients to
clinical  sites,  the  eligibility  criteria  for the study,  the  existence  of
competitive clinical trials and the availability of alternative  treatments.  In
particular,  the patient population for some of our potential products is small.
Delays in planned  patient  enrollment may result in increased costs and program
delays.

     We rely on  third-party  clinical  investigators  to conduct  our  clinical
trials. As a result, we may encounter delays outside of our control.



     We may not be able to reinitiate a clinical  trial that has been  suspended
by the FDA

     Clinical  trials are subject to ongoing  review by the FDA. The FDA has the
authority to suspend a clinical trial for various reasons,  as they did in April
2000 with  respect to our  clinical  trial using  porcine  neural cells to treat
stroke patients.  Because our products are novel and complex, getting the FDA to
lift a suspension  could result in  significant  program  delays and  additional
costs to us. It is possible  that we may not be able to obtain  permission  from
the FDA to continue a clinical trial that has been suspended. Cost increases and
ongoing delays as a result of an FDA suspension  could result in our decision to
postpone pursuing certain product candidates.

     The  regulatory  approval  process is costly and  lengthy and we may not be
able to successfully obtain all required regulatory approvals

     We must  obtain  regulatory  approval  for each of our  product  candidates
before we can  market or sell it. We may not  receive  regulatory  approvals  to
conduct  clinical  trials  of our  products  or to  manufacture  or  market  our
products.  In addition,  regulatory agencies may not grant approvals on a timely
basis or may revoke previously  granted  approvals.  Any delay in obtaining,  or
failure  to obtain,  approvals  could  adversely  affect  the  marketing  of our
products and our ability to generate product revenue.

     The process of obtaining  FDA and other  required  regulatory  approvals is
lengthy  and  expensive.  The time  required  for FDA and  other  clearances  or
approvals is uncertain and typically  takes a number of years,  depending on the
complexity and novelty of the product. We have only limited experience in filing
and prosecuting applications necessary to gain regulatory approvals.

     Our analysis of data obtained from  preclinical and clinical  activities is
subject to confirmation and interpretation by regulatory authorities which could
delay, limit or prevent regulatory approval. Any regulatory approval to market a
product may be subject to  limitations  on the  indicated  uses for which we may
market the product.  These  limitations may limit the size of the market for the
product.

     We also are subject to numerous foreign regulatory  requirements  governing
the  design  and  conduct  of the  clinical  trials  and the  manufacturing  and
marketing of our future products. The approval procedure varies among countries.
The time required to obtain foreign  approvals  often differs from that required
to obtain FDA approvals.  Moreover, approval by the FDA does not ensure approval
by regulatory authorities in other countries.

     Even if we obtain  marketing  approval,  our  products  will be  subject to
ongoing regulatory oversight which may affect the success of our products

     Any  regulatory  approvals  that we receive for a product may be subject to
limitations  on the  indicated  uses for which the  product  may be  marketed or
contain  requirements  for costly  post-marketing  follow-up  studies.  After we
obtain   marketing   approval  for  any  product,   the   manufacturer  and  the
manufacturing  facilities  for that product will be subject to continual  review
and  periodic  inspections  by the FDA and  other  regulatory  authorities.  The
subsequent  discovery of previously  unknown problems with the product,  such as
the  presence  of PERV,  or with the  manufacturer  or  facility,  may result in
restrictions on the product or manufacturer, including withdrawal of the product
from the market.



     If we fail to comply with  applicable  regulatory  requirements,  we may be
subject to fines,  suspension or withdrawal  of  regulatory  approvals,  product
recalls, seizure of products, operating restrictions, and criminal prosecution.

Risks Relating to Financing Our Business

     We have incurred  substantial losses, we expect to continue to incur losses
and we may never achieve profitability

     We have  incurred  losses  in each  year  since our  founding  in 1989.  At
December 31, 2000, we had an accumulated  deficit of $47.8 million. We expect to
incur  substantial  operating  losses  for the  foreseeable  future.  We have no
material  sources of revenue from product  sales or license  fees. We anticipate
that it will be a number  of  years,  if ever,  before  we  develop  significant
revenue  sources  or  become  profitable,  even if we are able to  commercialize
products.

     We expect to increase our spending  significantly  as we continue to expand
our research and development  programs,  expand our clinical  trials,  apply for
regulatory approvals and begin commercialization  activities.  In particular, we
intend to devote  significant  economic  resources to funding our joint  venture
with  Genzyme  and to its product  development  plans.  Under the joint  venture
agreement,  we are currently required to provide 25% of the funding required for
the development and  commercialization  of NeuroCell-PD  and NeuroCell-HD and in
the future will be required to provide 50% of the required funding.

     We may require additional  financing,  which may be difficult to obtain and
may dilute our ownership interest

     We will require  substantial  funds to conduct  research  and  development,
including  clinical  trials of our product  candidates,  and to manufacture  and
market any products that are approved for  commercial  sale. We believe that our
existing  funds,  together with expected  future funding under the joint venture
agreement  with Genzyme will be sufficient  to fund our  operating  expenses and
capital  requirements as currently planned for the foreseeable future.  However,
our future  capital  requirements  will depend on many  factors,  including  the
following:

     - continued progress in our research and development programs, as well as
       the magnitude of these programs;

     - the resources required to successfully complete our clinical trials;

     - the time and costs involved in obtaining regulatory approvals;

     - the cost of manufacturing and commercialization activities;

     - the cost of any additional facilities requirements;

     - the timing, receipt and amount of milestone and other payments from
       future collaborative partners;



     - the timing, receipt and amount of sales and royalties from our potential
       products in the market; and

     - the costs involved in preparing,  filing,  prosecuting,  maintaining  and
       enforcing  patent  claims  and  other  patent-related  costs,   including
       litigation  costs and the costs of  obtaining  any  required  licenses to
       technologies.

     We may seek  additional  funding  through  collaborative  arrangements  and
public or private financings. Additional financing may not be available to us on
acceptable terms or at all.

     If we raise additional funds by issuing equity securities  further dilution
to our then  existing  stockholders  may result.  In addition,  the terms of the
financing may adversely  affect the holdings or the rights of our  stockholders.
If we are unable to obtain  funding on a timely  basis,  we may be  required  to
significantly curtail one or more of our research or development programs.

     We  also  could  be  required  to  seek  funds  through  arrangements  with
collaborative  partners or others that may  require us to  relinquish  rights to
certain of our  technologies,  product  candidates,  or products  which we would
otherwise pursue independently.

Risks Relating to Intellectual Property

     We may not be able to obtain patent  protection for our  discoveries and we
may infringe patent rights of others

     The  patent  positions  of  pharmaceutical  and  biotechnology   companies,
including us, are generally uncertain and involve complex legal,  scientific and
factual issues.

     Our success depends significantly on our ability to:

     - obtain patents;

     - protect trade secrets;

     - operate without infringing upon the proprietary rights of others; and

     - prevent others from infringing on our proprietary rights.

     Patents may not issue from any patent  applications that we own or license.
If patents do issue, the claims allowed may not be sufficiently broad to protect
our  technology.  In  addition,  issued  patents  that we own or license  may be
challenged,  invalidated  or  circumvented.  Our patents  also may not afford us
protection  against   competitors  with  similar   technology.   Because  patent
applications in the United States are maintained in secrecy until patents issue,
others may have filed or maintained  patent  applications for technology used by
us or covered by our  pending  patent  applications  without  our being aware of
these applications.



     We may not hold proprietary  rights to some patents related to our proposed
products.  In some cases,  others may own or control these patents. As a result,
we or our  collaborative  partners  may be  required  to obtain  licenses  under
third-party patents to market some of our proposed products. If licenses are not
available  to us on  acceptable  terms,  we will  not be able  to  market  these
affected products.

     If we are not able to keep our trade secrets  confidential,  our technology
and information may be used by others to compete against us

     We rely significantly upon unpatented proprietary technology,  information,
processes and know how. We seek to protect this  information by  confidentiality
agreements with our employees,  consultants and other third-party contractors as
well as through other security measures. These confidentiality agreements may be
breached,  and we may not  have  adequate  remedies  for  any  such  breach.  In
addition,  our trade  secrets may  otherwise  become  known or be  independently
developed by competitors.

     We may become involved in expensive patent litigation or other intellectual
property  proceedings  which could result in  liability  for damages or stop our
development and commercialization efforts

     There has been substantial  litigation and other proceedings  regarding the
complex patent and other intellectual  property rights in the pharmaceutical and
biotechnology  industries.  We may become a party to patent  litigation or other
proceedings regarding intellectual property rights.

     Other  types of  situations  in  which we may  become  involved  in  patent
litigation or other intellectual property proceedings include:

     - we may initiate litigation or other proceedings against third parties to
       enforce our patent rights;

     - we may initiate  litigation or other proceedings against third parties to
       seek to invalidate the patents held by these third parties or to obtain a
       judgment that our products or services do not infringe the third parties'
       patents;

     - if our competitors  file patent  applications  that claim technology also
       claimed  by  us,  we  may   participate  in  interference  or  opposition
       proceedings to determine the priority of invention; and

     - if third  parties  initiate  litigation  claiming  that our  processes or
       products infringe their patent or other intellectual  property rights, we
       will need to defend against such claims.

     The  cost to us of any  patent  litigation  or  other  proceeding,  even if
resolved in our favor, could be substantial. Some of our competitors may be able
to sustain the cost of such litigation or proceedings  more  effectively than we
can because of their  substantially  greater  financial  resources.  If a patent
litigation or other intellectual  property proceeding is resolved unfavorably to
us, we may be enjoined from  manufacturing  or selling our products and services
without  a license  from the other  party  and be held  liable  for  significant
damages.  We may not be able to obtain  any  required  license  on  commercially
acceptable terms or at all.



     Uncertainties  resulting  from the initiation  and  continuation  of patent
litigation  or other  proceedings  could have a material  adverse  effect on our
ability to compete in the marketplace.  Patent  litigation and other proceedings
may also absorb significant management time.

     If we breach any of the agreements  under which we license  technology from
others we could lose license rights that are important to our business

     We are a party to technology in-licenses that are important to our business
and expect to enter into additional  licenses in the future. In particular,  our
immunomodulation  technology  and some of our product  candidates are covered by
patents licensed from  Massachusetts  General Hospital,  commonly referred to as
MGH. These licenses impose commercialization,  sublicensing,  royalty, insurance
and other obligations on us. If we fail to comply with these  requirements,  the
licensor will have the right to terminate the license.

Risks Relating to Product Manufacturing, Marketing and Sales

     Since we have no sales and marketing experience or infrastructure,  we must
rely on third parties

     We have no sales, marketing and distribution  experience or infrastructure.
We plan to rely significantly on sales, marketing and distribution  arrangements
with third parties for the products that we are developing.  For example,  under
our joint venture agreement,  we have granted to Genzyme (on behalf of the joint
venture) exclusive  worldwide marketing rights to NeuroCell-PD and NeuroCell-HD.
We may have limited or no control  over the sales,  marketing  and  distribution
activities of Genzyme, the joint venture or any future  collaborative  partners.
Our future revenues will be materially dependent upon the success of the efforts
of these third parties.

     If in the future we determine to perform sales,  marketing and distribution
functions ourselves, we would face a number of additional risks, including:

     - we may not be able to attract and build a significant marketing or sales
       force;

     - the cost of establishing a marketing or sales force may not be
       justifiable in light of any product revenues; and

     - our direct sales and marketing efforts may not be successful.

     Delays in obtaining  regulatory approval of our manufacturing  facility and
disruptions   in  our   manufacturing   process   may  delay  or   disrupt   our
commercialization efforts



     Before we can begin commercially  manufacturing our product candidates,  we
must obtain  regulatory  approval of our  manufacturing  facility  and  process.
Manufacturing  of our product  candidates  must  comply  with cGMP,  and foreign
regulatory  requirements.  The cGMP  requirements  govern  quality  control  and
documentation  policies  and  procedures.  In  complying  with cGMP and  foreign
regulatory  requirements,  we will be obligated to expend time, money and effort
on  production,  recordkeeping  and  quality  control to ensure that the product
meets applicable  specifications  and other  requirements.  If we fail to comply
with these  requirements,  we would be subject to possible regulatory action and
may be  limited  in the  jurisdictions  in  which we are  permitted  to sell our
product candidates.

     We and  our  joint  venture  are  the  only  manufacturers  of our  product
candidates.  For the next several  years,  we expect that we will conduct all of
our manufacturing in our facility in Charlestown, Massachusetts and at the joint
venture's  facility in  Framingham,  Massachusetts.  If these  facilities or the
equipment in these facilities is significantly damaged or destroyed, we will not
be able to quickly or inexpensively replace our manufacturing capacity.

     We have no experience  manufacturing  NeuroCell-PD in the volumes that will
be necessary to support large clinical trials or commercial  sales.  Our present
manufacturing  process may not meet our initial  expectations  as to scheduling,
reproducibility, yield, purity, cost, potency or quality.

     The  manufacture  of our products  would be delayed by  disruptions  in our
supply of porcine tissue

     The  manufacture of our products  requires the continuous  availability  of
porcine tissue  harvested  from pigs tested to be free of infectious  agents and
quarantined in a qualified animal facility. Our main sources of these facilities
and  services  are  Tufts   University   School  of   Veterinary   Medicine  and
PharmServices,  Inc., a division of Charles River  Laboratories,  Inc. A disease
epidemic or other catastrophe in either of these facilities could destroy all or
a portion of our pig supply,  which would interrupt or  significantly  delay the
research, development and commercialization of our products.

Risks Related to Ongoing Operations

     If we fail to obtain an  adequate  level of  reimbursement  for our  future
products by third party payors,  there may be no commercially viable markets for
our products

     Our products may be more expensive  than  conventional  treatments  because
they involve the surgical  transplantation  of living cells. The availability of
reimbursement  by governmental and other  third-party  payors affects the market
for any pharmaceutical  product. These third-party payors continually attempt to
contain or reduce the costs of health care by challenging the prices charged for
medical products.  In some foreign countries,  particularly the countries of the
European  Union,  the  pricing  of  prescription  pharmaceuticals  is subject to
governmental  control.  We may not be able to sell our  products  profitably  if
reimbursement is unavailable or limited in scope or amount.

     In both the United States and some foreign jurisdictions, there have been a
number of legislative and regulatory proposals to change the health care system.
Further proposals are likely.  The potential for adoption of these proposals may
affect our ability to raise capital,  obtain additional  collaborative  partners
and market our products.



     If we obtain marketing  approval for our products,  we expect to experience
pricing  pressure due to the trend toward  managed  health care,  the increasing
influence  of  health  maintenance   organizations  and  additional  legislative
proposals.

     We could be exposed  to  significant  liability  claims if we are unable to
obtain  insurance  at  acceptable  costs or  otherwise  to  protect  us  against
potential product liability claims

     We may be  subjected to product  liability  claims that are inherent in the
testing, manufacturing,  marketing and sale of human health care products. These
claims  could  expose  us to  significant  liabilities  that  could  prevent  or
interfere with the  development or  commercialization  of our products.  Product
liability  claims  could  require  us to spend  significant  time  and  money in
litigation  or to  pay  significant  damages.  Product  liability  insurance  is
generally  expensive for  biopharmaceutical  companies such as ours. Although we
maintain limited product liability insurance coverage for the clinical trials of
our products,  it is possible that we will not be able to obtain further product
liability  insurance  on  acceptable  terms,  if at all,  and that  our  present
insurance levels and insurance  subsequently  obtained will not provide adequate
coverage against all potential claims.

     Our growth  could be  limited  if we are  unable to attract  and retain key
personnel and consultants

     Our  success  depends  substantially  on our  ability to attract and retain
qualified  scientific and technical  personnel for the research and  development
activities  we conduct or sponsor.  If we lose one or more of the members of our
senior  management  or other key  employees  or  consultants,  our  business and
operating results could be seriously harmed.

     Our  anticipated  growth and expansion into areas and activities  requiring
additional  expertise,   such  as  regulatory   compliance,   manufacturing  and
marketing,  will require the addition of new management  personnel.  The pool of
personnel  with the skills that we require is limited.  Competition to hire from
this limited  pool is intense,  and we may be unable to hire,  train,  retain or
motivate such additional personnel.

Risks Relating to our Common Stock

     Our  officers  and  directors  may be able to control  the  outcome of most
corporate actions requiring stockholder approval

     Our  directors  and officers and  entities  with which they are  affiliated
control  approximately  40%  of  our  outstanding  common  stock.  Due  to  this
concentration  of  ownership,  this group may be able to prevail on all  matters
requiring a stockholder vote, including:

     - the election of directors;

     - the amendment of our organizational documents; or

     - the approval of a merger, sale of assets or other major corporate
       transaction.





     Our stock  price could be  volatile,  which could cause you to lost part or
all of your investment

     The market price of our common stock, like that of the common stock of many
other  development stage  biotechnology  companies,  may be highly volatile.  In
addition,   the  stock  market  has   experienced   extreme   price  and  volume
fluctuations.  This volatility has  significantly  affected the market prices of
securities  of many  biotechnology  and  pharmaceutical  companies  for  reasons
frequently unrelated to or disproportionate to the operating  performance of the
specific  companies.  These broad market  fluctuations  may adversely affect the
market price of our common stock. Prices for our common stock will be determined
in the market place and may be influenced by many factors,  including variations
in  our  financial  results  and  investors'   perceptions  of  us,  changes  in
recommendations  by securities  analysts as well as their perceptions of general
economic, industry and market conditions.

     We have  antitakeover  defenses that could delay or prevent an  acquisition
and could adversely affect the price of our common stock

     Provisions of our certificate of  incorporation,  our bylaws,  and Delaware
law may have the  effect of  deterring  unsolicited  takeovers  or  delaying  or
preventing changes in control of our management, including transactions in which
our  stockholders  might otherwise  receive a premium for their shares over then
current market prices.  In addition,  these  provisions may limit the ability of
stockholders  to  approve  transactions  that they may deem to be in their  best
interest.

     Our  certificate of  incorporation  permits our board of directors to issue
preferred  stock  without  shareholder  approval upon such terms as the board of
directors may  determine.  The rights of the holders of our common stock will be
subject to, and may be  adversely  affected by, the rights of the holders of any
preferred  stock that may be issued in the future.  The  issuance  of  preferred
stock,  while  providing  desirable  flexibility  in  connection  with  possible
acquisitions  and other corporate  purposes,  could have the effect of making it
more  difficult for a third party to acquire,  or of  discouraging a third party
from acquiring,  a majority of our outstanding  common stock.  The issuance of a
substantial  number of preferred  shares could adversely affect the price of our
common stock.

Item 7A.Quantitative and Qualitative Disclosures About Market Risk

         We own financial instruments that are sensitive to market risks as part
of its investment  portfolio.  The investment  portfolio is used to preserve our
capital  until it is required to fund  operations,  including  our  research and
development activities. None of these market-risk sensitive instruments are held
for trading  purposes.  We do not own  derivative  financial  instruments in our
investment  portfolio.  The investment  portfolio contains  instruments that are
subject to the risk of a decline in interest rates.

         Our investment  portfolio  includes  investment grade debt instruments.
These  bonds are subject to interest  rate risk,  and could  decline in value if
interest rates fluctuate.  Due to the short duration and conservative  nature of
these instruments, we do not believe that it has a material exposure to interest
rate risk.

                    Report of Independent Public Accountants

To the Board of Directors of
Diacrin, Inc.:

         We have audited the  accompanying  balance  sheets of Diacrin,  Inc. (a
Delaware  corporation)  as of  December  31,  1999  and  2000  and  the  related
statements of  operations,  stockholders'  equity and cash flows for each of the
three years in the period ended December 31, 2000.  These  financial  statements
are the responsibility of the Diacrin, Inc.'s management.  Our responsibility is
to express an opinion on these financial statements based on our audits.

         We conducted our audits in accordance with auditing standards generally
accepted in the United States.  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,  the  financial  statements  referred to above  present
fairly, in all material respects,  the financial position of Diacrin, Inc. as of
December 31, 1999 and 2000 and the results of its  operations and its cash flows
for each of the three years in the period ended December 31, 2000, in conformity
with accounting principles generally accepted in the United States.

                                              Diacrin, Inc.

                                      Notes to Financial Statements

(1)      Operations and Basis of Presentation

         Diacrin,  Inc. (the "Company") was incorporated on October 10, 1989 and
is  developing  cell  transplantation  technology  for the  treatment  of  human
diseases that are  characterized by cell dysfunction or cell death and for which
current therapies are either inadequate or nonexistent.

(2)      Summary of Significant Accounting Policies

         (a)      Depreciation and Amortization

         The Company provides for depreciation using the straight-line method by
charges to operations in amounts  estimated to allocate the cost of these assets
over a five-year life.  Amortization of leasehold improvements is computed using
the  straight-line  method over the shorter of the estimated  useful life of the
asset or the lease term.

         (b)      Research and Development

     Collaborative  revenue  under  the joint  venture  agreement  with  Genzyme
Corporation  ("Genzyme")  (see Note 4) and  revenues  from  research  grants are
recognized as work is performed.  Collaborative  revenue under the joint venture
agreement is recognized as revenue to the extent that the Company's research and
development  costs are funded by Genzyme through the joint venture.  The Company
receives  non-refundable  monthly  advances  from the  joint  venture.  Deferred
revenue  represents  amounts received prior to recognition of revenue.  Research
and development costs are expensed as incurred.

         (c)      Income Taxes

         The Company  accounts for income taxes in accordance  with Statement of
Financial Accounting Standards ("SFAS") No. 109, Accounting for Income Taxes. At
December 31, 2000, the Company has a net operating loss carryforward for federal
income tax purposes of  approximately  $49,750,000.  The difference  from losses
reported  for  financial   reporting  purposes  relates  primarily  to  expenses
reflected in the financial  statements not yet deductible for tax purposes.  The
net  operating  loss  carryforwards  expire  commencing in the year 2006 and are
subject to review and possible  adjustment by the Internal Revenue Service.  Net
operating  loss and tax  credit  carryforwards  may be  limited  in the event of
certain  changes in the ownership  interests of  significant  shareholders.  The
Company  believes the issuance of the convertible  notes payable in May 1995, as
well as the  initial  public  offering  in  February  1996,  caused a change  in
ownership,  as defined by the Tax Reform Act of 1986 (the "Act").  Additionally,
the Company's private placement in 1998 and secondary offering in 2000 may cause
a change in ownership,  as defined by the Act. The Company does not believe that
such  ownership  changes  will  significantly  impact the  Company's  ability to
utilize the net operating  loss and tax credit  carryforwards  as of the date of
such  ownership  changes.  Ownership  changes  in future  periods  may limit the
Company's ability to utilize net operating loss and tax credit carryforwards.

                   Notes to Financial Statements - (Continued)

The components of the net deferred tax assets are approximately as follows:

                                              1999                     2000
                                              ----                     ----
Loss carryforwards                   $      16,403,000       $      19,900,000
Credit carryforwards                         3,815,000               4,900,000
Other temporary differences                     10,000                  13,500
                                     -----------------       -----------------
Total deferred tax assets                   20,228,000              24,813,500
Less - valuation allowance                 (20,228,000)            (24,813,500)
                                     -----------------       ------------------
Net deferred tax asset               $          -            $           -
                                      =================       ==================

         A  valuation  allowance  has been  provided as it is  uncertain  if the
Company will realize the deferred tax assets.  The change in the total valuation
allowance   during  the  year  ended  December  31,  2000  was  an  increase  of
approximately  $4,585,500  and relates to the increase in the deferred tax asset
which is  primarily  due to the net  operating  loss and tax  credits  generated
during 2000.

         (d)      Net Loss per Common Share

     In accordance with SFAS No. 128, Earnings per Share,  basic and diluted net
loss per share is  calculated  by dividing the net loss by the weighted  average
number of common shares outstanding for all periods presented.  Diluted weighted
average  shares  outstanding  for all periods  presented  exclude the  potential
common  shares from stock  options  and  warrants of  4,000,738,  4,111,523  and
1,258,247 at December 31, 1998, 1999, and 2000, respectively, because to include
such shares would have been antidilutive.

         (e)      Use of Estimates

         The  preparation of financial  statements in conformity with accounting
principles  generally accepted in the United States requires  management to make
estimates  and  assumptions  that  affect  the  reported  amounts  of assets and
liabilities at the date of the financial  statements and the reported amounts of
expenses  during the reporting  period.  Actual  results could differ from those
estimates.

         (f)      Reclassifications

         Certain  prior year  amounts have been  reclassified  to conform to the
current year presentation.

         (g)      Comprehensive Income

     In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130,  Reporting  Comprehensive  Income  ("SFAS 130").  SFAS 130  establishes
standards for reporting and display of  comprehensive  income and its components
(revenues,  expenses,  gains  and  losses)  in a  full  set  of  general-purpose
financial  statements.  This  statement is effective for fiscal years  beginning
after December 15, 1997.  The Company  adopted this statement for the year ended
December 31, 1998 with no impact on the Company's financial  statements as there
are  no  material   differences   between  the  Company's  reported  income  and
comprehensive income for all periods presented.

                   Notes to Financial Statements - (Continued)

         (h)      Segment Reporting

         In June 1997, the FASB issued SFAS No. 131,  Disclosure  about Segments
of an Enterprise  and Related  Information  ("SFAS 131").  SFAS 131  establishes
standards for the way that public business  enterprises report information about
operating segments in annual financial  statements and requires that enterprises
report  selected  information  about  operating  segments  in interim  financial
reports issued to stockholders.  The Company adopted this statement for the year
ended December 31, 1998. In accordance with SFAS 131, the Company  believes that
it operates in one operating segment.

         (i)      Fair Value of Financial Instruments

     Financial   instruments  consist  mainly  of  cash  and  cash  equivalents,
short-term investments, long-term investments, accounts payable, current portion
of long-term debt and long-term debt. The carrying amounts of these  instruments
approximate their fair value.

         (j)      New Accounting Standards

     In June 1998,  the FASB  issued  SFAS No. 133,  Accounting  for  Derivative
Instruments and Hedging  Activities.  The statement (as amended by SFAS No. 137)
is effective for all fiscal  quarters of all fiscal years  beginning  after June
15, 2000. SFAS No. 133 (as amended by SFAS No. 138)  establishes  accounting and
reporting  standards for derivative  instruments  including  certain  derivative
instruments   embedded  in  other   contracts   (collectively   referred  to  as
derivatives) and for hedging activities. The Company does not expect adoption of
this statement to have a material impact on the Company's financial statements.

                   Notes to Financial Statements - (Continued)

     In December  1999,  the  Securities  and Exchange  Commission  issued Staff
Accounting Bulletin (SAB) No. 101, Revenue Recognition in Financial  Statements.
SAB No. 101,  as  amended,  is  effective  for the fourth  quarter of all fiscal
periods beginning after December 15, 1999.  Adoption of SAB No. 101 did not have
a material impact on the Company's financial position or results of operations.

 (3)     Sales of Common Stock

         In  February  1998,  the  Company  completed  a  private  placement  of
1,027,027  shares of its common  stock for $9.25 per share for net  proceeds  of
approximately $9.4 million.

         In March 2000,  the Company  completed a public  offering of  3,450,000
shares  of  its  common   stock  for  $11.50  per  share  for  net  proceeds  of
approximately $36.9 million.

(4)      Joint Venture Agreement

     In  September  1996,  the Company and  Genzyme  Corporation  formed a joint
venture to develop and commercialize the Company's NeuroCell-PD and NeuroCell-HD
products for transplantation  into people with advanced  Parkinson's disease and
Huntington's  disease,  respectively.  Under  the  terms  of the  joint  venture
agreement,  which was effective October 1, 1996,  Genzyme agreed to provide 100%
of the first $10  million in funding  and 75% of the  following  $40  million in
funding for the two products.  All costs  incurred in excess of $50 million will
be shared equally  between  Genzyme and the Company in accordance with the terms
of the agreement. Any profits of the joint venture will be shared equally by the
two parties.  As of December 31, 2000, Genzyme had provided $29.7 million to the
joint venture and the Company had provided $6.5 million.

         The  Company  records as  research  and  development  expense all costs
related to NeuroCell-PD and  NeuroCell-HD  incurred by it on behalf of the joint
venture.  The Company recognizes  research and development  revenue equal to the
amount  of  reimbursement  received  by it from the joint  venture  out of funds
contributed by Genzyme.  The Company does not recognize research and development
revenue for amounts received from the joint venture out of funds it contributed.
As  Genzyme  incurs  costs on behalf of the joint  venture  that the  Company is
obligated to fund,  it  recognizes  an expense in its  statement  of  operations
captioned "Equity in operations of joint venture."

                   Notes to Financial Statements - (Continued)

         Genzyme  agreed to make  financing  available to Diacrin from and after
the date that  Genzyme  provides the initial $10 million of funding to the joint
venture. Genzyme agreed to make available to Diacrin an unsecured,  subordinated
line of credit of up to an aggregate amount of $10 million.  Diacrin may draw on
the  line  only in the  event  that  Diacrin's  cash and  cash  equivalents  are
insufficient  to fund Diacrin's  budgeted  operations for a specified  period of
time, and the funds may be used by Diacrin only to fund capital contributions to
the joint venture.  The line will be available through the date five years after
the date Diacrin  first draws on the line,  and all  outstanding  principal  and
interest   will   be  due  on  that   fifth   anniversary.   Advances   will  be
interest-bearing,   evidenced  by  a  promissory   note  and  subject  to  other
considerations   and the aggregate  amount of draws in any calendar year may not
exceed $5 million.  Diacrin did not make any draws on the line through  December
31, 2000.

         The Company  accounts for its  investment  in the joint  venture on the
equity method. The detail of the Company's investment in the joint venture is as
follows:

     The  Company  has  adopted  SFAS  No.  123,   Accounting  for   Stock-Based
Compensation. As permitted by SFAS No. 123, the Company has continued to account
for employee  stock  options in  accordance  with  Accounting  Principles  Board
Opinion No. 25,  Accounting for Stock Issued to Employees,  and has included the
proforma disclosure required by SFAS No. 123 for all periods presented.

         Pro forma  information  regarding net income (loss) and earnings (loss)
per share is required by SFAS No. 123, and has been determined as if the Company
had accounted  for its employee and director  stock options under the fair value
method of SFAS No. 123. The  fair-value  for these  options was estimated at the
date of grant using a  Black-Scholes  option  pricing  model with the  following
assumptions for 1998, 1999 and 2000:  risk-free interest rates of 5.5%, 6.0% and
6.0%, respectively; dividend yield of 0% for all years; volatility factor of the
expected  market  price  of the  Company's  common  stock  of 70%,  95% and 95%,
respectively;  and a weighted-average  expected life of the options of 7.5 years
for all years.  The weighted average fair value of options granted in 1998, 1999
and 2000 was $4.68, $4.97 and $4.71, respectively.

                        Report of Independent Accountants


To the Steering Committee of Diacrin/Genzyme LLC:

In our opinion,  the accompanying  balance sheets and the related  statements of
operations, of cash flows and of changes in Venturers' capital (deficit) present
fairly, in all material respects,  the financial position of Diacrin/Genzyme LLC
(a development  stage enterprise) at December 31, 1999 and 2000, and the results
of its operations and its cash flows for the years then ended and for the period
from October 1, 1996 (date of  inception)  to December 31, 2000,  in  conformity
with accounting  principles  generally accepted in the United States of America.
These financial  statements are the  responsibility of the Steering Committee of
the  Joint  Venture;  our  responsibility  is to  express  an  opinion  on these
financial  statements  based on our  audits.  We  conducted  our audits of these
statements  in  accordance  with auditing  standards  generally  accepted in the
United  States of America,  which  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,  assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

As  more  fully   discussed  in  Note  A,  either  Venturer  may  terminate  the
Collaboration Agreement of the Joint Venture for any reason upon 180 days notice
to the other Venturer and such termination could lead to the  discontinuation of
the Joint Venture.

                               Diacrin/Genzyme LLC
                        (A Development Stage Enterprise)

                          Notes to Financial Statements

A.       Nature of Business and Organization

     On  October  1,  1996,   Diacrin/Genzyme  LLC  ("the  Joint  Venture")  was
established  as a joint venture  between  Genzyme  Corporation  ("Genzyme")  and
Diacrin,  Inc.  ("Diacrin")  (collectively,  the  "Venturers"),  to develop  and
commercialize  products and processes  for use in the  treatment of  Parkinson's
disease and Huntington's  disease in humans using porcine fetal cells. Under the
terms of the  Collaboration  Agreement  among  Diacrin,  Genzyme  and the  Joint
Venture  (the  "Collaboration  Agreement"),  all  funding  is  provided  by  the
Venturers,  and all  payments  for work  performed  are  made to the  Venturers.
Genzyme provided the initial $10.0 million of the funding requirements,  and the
next $40.0 million of the funding requirements are to be provided 75% by Genzyme
and 25% by Diacrin.  After $50.0 million has been funded, any additional funding
will be  provided  equally by the  Venturers.  Funding is  provided on a monthly
basis. Profits and losses from the Joint Venture will be shared in proportion to
the then current capital contribution ratio of each Venturer.  The Joint Venture
reimburses  the  Venturers  for costs  incurred  based upon the dollar amount of
work,  at a defined  cost,  that each  Venturer  performs an behalf of the Joint
Venture.  All general and administrative  expenses recorded on the statements of
operations are for costs  incurred by and reimbursed to the Venturers.  See also
Note C.

         The  Steering   Committee   of  the  Joint   Venture  is  comprised  of
representatives  of each Venturer.  The Steering  Committee is  responsible  for
approving  the budget of the Joint  Venture,  reviewing  costs  incurred  by the
Venturers and monitoring the scientific progress of the Joint Venture.

     The  Joint  Venture  is  subject  to  risks  common  to  companies  in  the
biotechnology  industry,  including  but not limited to, the results of clinical
trials,  development  by  its  competitors  of  new  technological  innovations,
protection of proprietary technology,  health care cost containment initiatives,
product liability and compliance with government regulations, including those of
the United States  Department of Health and Human Services and the United States
Food and Drug Administration.

     In addition,  eiher Venturer may terminate the Collaboration  Agreement for
any  reason  upon 180 days  notice to the other  Venturer.  During  the  180-day
period,   the  obligations  of  the  Venturers,   including  without  limitation
obligations with respect to capital  contributions,  will continue in full force
and  effect.  A decision  by one or both of the  Venturers  to  discontinue  the
Collaboration  Agreement for any reason could lead to the discontinuation of the
Joint Venture.

                               Diacrin/Genzyme LLC
                        (A Development Stage Enterprise)

                          Notes to Financial Statements

         The intangible assets and technological know-how contributed by Diacrin
to the Joint Venture are not included as an asset in these financial statements,
because generally accepted accounting  principles require that the Joint Venture
record contributed assets at the book value of the Venturer,  at the time of the
asset transfer the book value was $0.

B.       Summary of Significant Accounting Policies

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

Cash and Cash Equivalents
         Cash and cash equivalents, consisting principally of money market funds
and municipal notes  purchased with initial  maturities of three months or less,
are valued at cost plus accrued interest, which approximates market.

Property and Equipment
         Depreciation  expense is  computed  on a  straight-line  basis over the
useful life of the property and  equipment (3 to 10 years),  and over the lesser
of the life of the lease or the life of the leasehold  improvement.  When assets
are retired or  otherwise  disposed  of, the assets and the related  accumulated
depreciation are removed from the accounts and any resulting gains or losses are
included in the results of operations.

Research and Development Expenses
         Research and development  costs are expensed as incurred.  The research
and development efforts are being conducted by the Venturers. The costs incurred
by these related parties,  which are subject to an annual budget approved by the
Joint Venture's Steering Committee,  are then charged to the Joint Venture, at a
defined cost, or at amounts agreed to by the Venturers.

Income Taxes
         The Joint Venture is organized as a pass-through  entity;  accordingly,
the financial  statements do not include a provision for income taxes. Taxes, if
any, are the liability of Genzyme and Diacrin, as Venturers.

Reclassification
         Certain  prior year data has been  reclassified  to conform to the 2000
presentation.

                   Notes to Financial Statements - (Continued)

C.       Agreements with Venturers

Funding
         Genzyme agreed to make available to Diacrin an unsecured,  subordinated
line of credit (the "Line") of up to an aggregate  amount of $10.0 million after
the date that Genzyme provided the initial $10.0 million of funding to the Joint
Venture.  Diacrin may draw on the Line only in the event that Diacrin's cash and
cash  equivalents are insufficient to fund Diacrin's  budgeted  operations for a
specified  period of time,  and the funds  may be used by  Diacrin  only to fund
capital  contributions to the Joint Venture.  The Line will be available through
the date five years  after the date  Diacrin  first  draws on the Line,  and all
outstanding  principal  and  interest  will  be due on that  fifth  anniversary.
Advances will be interest bearing, evidenced by a promissory note and subject to
other considerations; and the aggregate amount of draws in any calendar year may
not exceed $5.0 million. As of December 31, 2000, Diacrin had not made any draws
on the Line.

         During the year ended December 31, 1998,  Genzyme  provided its initial
$10.0 million of funding to the Joint Venture.  After the initial $10.0 million,
Genzyme and Diacrin provide 75% and 25%, respectively, of the next $40.0 million
of funding to the Joint Venture.  Thereafter, all funding will be shared equally
by the two parties.  As of December  31,  2000,  Genzyme and Diacrin have funded
$29.7 million and $6.5 million, respectively.

Other Agreements
         The payable to Genzyme  Corporation will be settled by cash payment and
represents   costs  incurred  by  Genzyme  that  are   reimbursable   under  the
Collaboration   Agreement.  The  prepaid  to  Diacrin  is  an  estimate  of  the
reimbursable  costs  Diacrin  expects to incur on behalf of the Joint Venture in
the next month.

         At December  31,  1999 and 2000,  both  Venturers  had funded less than
their  allocated  losses  which  resulted  in  unpaid  Venturer's   capital  and
represents receivables from the Venturers.

         Genzyme  charges  the Joint  Venture  for use of certain  research  and
development  facilities  under a three-year  agreement  which  commenced July 1,
1998.  These charges  amounted to $364,164 for each of the years ended  December
31, 1999 and 2000 and $1,338,720  from inception  through  December 31, 2000 and
the Joint  Venture  expects to incur  $182,082 in the year ending  December  31,
2001.
