                          Notes to Financial Statements
                                   (Unaudited)

1.       Operations and Basis of Presentation

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

         The  financial  statements  included  herein have been  prepared by the
Company,  without audit, pursuant to the rules and regulations of the Securities
and  Exchange  Commission  and  include,  in  the  opinion  of  management,  all
adjustments,  consisting of normal, recurring adjustments,  necessary for a fair
presentation  of  interim  period  results.  Certain  information  and  footnote
disclosures  normally  included in financial  statements  prepared in accordance
with generally  accepted  accounting  principles  have been condensed or omitted
pursuant to such rules and regulations.  The Company believes, however, that its
disclosures are adequate to make the information  presented not misleading.  The
results for the interim  periods  presented  are not  necessarily  indicative of
results to be expected  for the full fiscal  year.  These  financial  statements
should be read in conjunction  with the audited  financial  statements and notes
thereto  included in the Company's  latest Annual Report on Form 10-K filed with
the Securities and Exchange Commission.

2.       Summary of Significant Accounting Policies

         (a)      Research and Development

         In  September  1996,  the Company and Genzyme  Corporation  ("Genzyme")
formed a joint  venture  (the  "Joint  Venture")  to develop  and  commercialize
NeuroCell(TM)-PD  for Parkinson's disease and  NeuroCell(TM)-HD for Huntington's
disease (the "Joint Venture  Products").  The Joint Venture is funded by Genzyme
and the Company in  accordance  with the terms of the joint  venture  agreement.
Collaborative  revenue  under  the  joint  venture  agreement  with  Genzyme  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.

         (b)      Net Loss per Common Share

          In  accordance  with  Statement  of  Financial   Accounting  Standards
("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  3,967,213  and  4,043,247 at March 31, 1999 and
2000, respectively, because to include such shares would be antidilutive.

                                   (Unaudited)

         (c)       New Accounting Standards

         In June 1998,  the FASB issued SFAS No. 133,  Accounting for Derivative
Instruments  and Hedging  Activities.  The  statement is effective  for the year
ended  December 31, 2000.  SFAS No. 133  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.

         In March 2000, the FASB issued  Interpretation  No. 44, "Accounting for
Certain  Transactions  Involving Stock  Compensation" an  Interpretation  of APB
Opinion No. 25. The interpretation  clarifies the application of APB Opinion No.
25 in certain  situations,  as defined.  The Interpretation is effective July 1,
2000, but covers certain events  occurring  during the period after December 15,
1998,  but before the effective  date. To the extent that events covered by this
interpretation  occur during the period after December 15, 1998, but before July
1, 2000,  the effects of applying this  interpretation  would be recognized on a
prospective basis from the effective date. Accordingly, upon initial application
of the final  interpretation,  (a) no adjustments would be made to the financial
statements  for periods  before the  effective  date and (b) no expense would be
recognized for any additional compensation cost measured that is attributable to
periods  before  the  effective  date.  We  expect  that  the  adoption  of this
interpretation  will not  have a  material  impact  on the  Company's  financial
position or results of operations.

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

3.          Stock Offering

         In March 2000,  the Company  completed  a stock  offering of  3,450,000
shares  of  its  common   stock  for  $11.50  per  share  for  net  proceeds  of
approximately $37 million.

4.       Cash Equivalents and Investments

         The  Company's  cash  equivalents  and  investments  are  classified as
held-to-maturity  and are carried at amortized cost, which  approximates  market
value. Cash equivalents,  short-term  investments and long-term investments have
maturities  of less than three  months,  less than one year and greater than one
year,  respectively.  Cash  equivalents,  short-term  investments  and long-term
investments at December 31, 1999 and March 31, 2000 consisted of the following:

Item 2. 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,  commencing 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 March 31, 2000, we
had an accumulated deficit of $45.5 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 March  31,  2000,  approximately  $24.9
million had been  contributed to the joint venture by Genzyme and  approximately
$5.0 million had been contributed by us. We expect that the joint venture's 2000
product  development  plans,  together with our  continued  funding of the joint
venture, will significantly  increase our net loss and cash and investments used
in 2000 as compared with 1999.

          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
received  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

Three Months Ended March 31, 2000 Versus Three Months Ended March 31, 1999

                  Research and development  revenues of  approximately  $536,000
for the three  months  ended March 31, 2000 and  $798,000  for the three  months
ended  March 31,  1999 were  derived  exclusively  from the Joint  Venture.  The
decrease in revenues was primarily a result of a decrease in clinical production
activity  related to the Joint Venture  products as the Joint Venture  completed
accruing patients into its Phase 2/3 clinical trial in 1999.

                                     - 9 -

<PAGE>



         Interest  income of $327,000  and  $358,000  for the three month period
ended March 31, 2000 and 1999, respectively, remained relatively unchanged.

         Research  and  development  expenses  were $1.4  million  for the three
months ended March 31, 2000 versus $1.6 million for the three months ended March
31,  1999.  This 14%  decrease  was  primarily  due to a  reduction  in clinical
production  activity as the Company's Joint Venture completed  accruing patients
into its Phase 2/3 clinical trial of NeuroCell(TM)-PD in 1999 and a reduction in
preclinical  related research as most of the Company's  product  candidates move
toward clinical testing.

         General and  administrative  expenses of $366,000  and $322,000 for the
three months ended March 31, 2000 and 1999,  respectively,  remained  relatively
unchanged between the periods.

         For the three  months  ended  March  31,  2000 and  1999,  the  Company
recorded  an expense of  $354,000  and  $467,000,  respectively,  related to its
equity  in  operations  of the  joint  venture.  This  expense  was due to funds
contributed  by the Company to the Joint Venture that were used to fund expenses
incurred by Genzyme on behalf of the Joint Venture.

         The Company incurred a net loss of  approximately  $1.2 million for the
three  months  ended March 31, 2000 versus  approximately  $1.3  million for the
three months ended March 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  $101  million and with the
interest  earned  thereon.  In addition,  we have recorded  approximately  $12.9
million in revenue from our joint venture since it commenced on October 1, 1996.
At March 31, 2000, we had cash and cash equivalents,  short-term investments and
long-term investments aggregating approximately $57.4 million.

         In February 1996, we issued redeemable  warrants in connection with our
initial  public  offering.  The  warrants  are  exercisable  for an aggregate of
2,875,000  shares of common stock at an exercise price of $16.00 per share.  The
warrants  expire on the earlier of  redemption of the warrants by us or December
31, 2000. We may redeem the warrants,  upon 30 days given notice, if the average
closing  price of the common  stock for any  20-consecutive-day  trading  period
exceeds 150% of the exercise  price of the  warrants.  The  redemption  price is
$0.01 per warrants. At March 31, 2000 there were 2,872,800 warrants outstanding.

         We have purchased approximately $2.3 million of capital equipment since
inception.  In November  1997, we borrowed  $650,000 at the prime rate plus 0.5%
(9.50% at March 31, 2000) under an unsecured  five-year term loan with a bank to
finance our biomedical  animal facility acquired during 1997. We had no material
commitments for capital expenditures as of March 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 March 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 or 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.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

         We own financial instruments that are sensitive to market risks as part
of our investment  portfolio.  The investment  portfolio is used to preserve our
capital  until we are 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 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 we  have a  material  exposure  to
interest rate risk.
