                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of HemaSure Inc.:

               In our opinion, the accompanying  consolidated balance sheets and
the  related  consolidated   statements  of  operations,   stockholders'  equity
(deficit) and cash flows present fairly, in all material respects, the financial
position of HemaSure Inc. at December 31, 1999 and 1998,  and the results of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1999, in conformity with accounting  principles  generally accepted
in the United States.  These financial  statements are the responsibility of the
Company's  management;  our  responsibility  is to  express  an opinion on these
financial  statements  based on our  audits.  We  conducted  our audits of these
statements  in  accordance  with auditing  standards  generally  accepted in the
United  States,  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 the opinion expressed above.

               The accompanying financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in Note A to the
financial statements,  the Company has suffered recurring losses from operations
which raise  substantial doubt about its ability to continue as a going concern.
Management's  plans in regard to these matters are also described in Note A. The
financial  statements do not include any adjustments  that might result from the
outcome of this uncertainty.

processing applications. Subsequently and throughout 1997, the Company's revenue
was derived from the commercial  sales of its LeukoNet  System, a medical device
designed for the removal of  contaminating  leukocytes  from donated  blood.  In
February 1998, the Company determined to discontinue  manufacturing the LeukoNet
System and focus on the completion of development and market introduction of its
next-generation  red cell filtration  product. In May 1999, the Company received
510(k) clearance from the U.S. Food and Drug Administration  (FDA) to market its
r/LS System in the United States. The Company initiated sales of the r/LS System
in the United States in the third quarter 1999.

        The  Company is  subject to risks  common to  companies  in the  medical
technology industry,  including,  but not limited to, development by the Company
or  its  competitors  of  new  technological  innovations,   dependence  on  key
personnel, protection of proprietary technology, and compliance with regulations
of the FDA and similar foreign regulatory authorities and agencies.

        Since its  inception,  the Company has  suffered  recurring  losses from
operations and accumulated  deficits.  These conditions raise  substantial doubt
about its ability to continue as a going  concern.  The ultimate  success of the
Company  is  dependent  upon its  ability  to raise  capital  through  strategic
partnerships,  public or private  equity  and/or debt  financing  and the market
acceptance of new products.  However,  the Company's  capital  requirements  may
change  depending upon numerous  factors,  including  compliance with regulatory
requirements,  the time necessary to commercialize the Company's new product and
the demand for the Company's product. No assurance can be given that the Company
will be able to obtain additional  financing on terms acceptable to the Company,
if at all,  or  that  the  Company  will  successfully  effect  the new  product
introduction  into the  market.  The  financial  statements  do not  include any
adjustments that might result from the outcome of this uncertainty.

        In view of the Company's current financial condition,  the Company plans
to manage  aggressively  its working capital and expenses while working to raise
capital.  The Company will also pursue product sales  opportunities,  as well as
strategic or other business relationships.

B.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Cash and Cash Equivalents

        The Company considers all demand deposits,  money market instruments and
repurchase  agreements  to be cash and cash  equivalents.  Cash  equivalents  of
$4,743,000  and  $2,138,000  and at December  31,  1999 and 1998,  respectively,
consist of repurchase  agreements  with a commercial  bank. The carrying  amount
approximates fair value because of the short maturity of those instruments.

Marketable Securities

        Management determines the appropriate  classification of its investments
in debt and equity  securities  at the time of  purchase.  The  Company  held no
marketable securities at December 31, 1999 and 1998.

<PAGE>



        Inventories  are stated at the lower of cost  (first-in,  first-out)  or
market.

Property and Equipment

        Property and equipment are stated at cost.  Costs of major additions and
betterments are  capitalized;  maintenance and repairs,  which do not improve or
extend  the  life of the  respective  assets,  are  charged  to  operations.  On
disposal,  the related cost and  accumulated  depreciation  or  amortization  is
removed  from the  accounts  and any  resulting  gain or loss is included in the
results of operations.  Depreciation is computed using the straight-line  method
over the estimated useful lives of the assets. All laboratory, manufacturing and
office equipment have estimated useful lives of three to 10 years.

Revenue Recognition

        Revenues from product sales are recognized when goods are shipped.

Research and Development

        Research and development costs are expensed in the year incurred.

Net Loss Per Share

        The Company follows Statement of Financial Accounting Standards No. 128,
"Earnings Per Share" ("SFAS 128"), which established standards for computing and
presenting earnings per share ("EPS"). Net loss per common share is based on the
weighted  average  number  of shares of common  stock  outstanding  during  each
period. Potential common stock has not been included because the effect would be
antidilutive.  The potential common stock of the Company consist of common stock
warrants  (See  Notes C and H),  stock  options  (see Note L) and a  convertible
subordinated note payable (see Note I). The Company had 4,757,000, 4,214,000 and
2,846,000 potential common stock shares as of December 31, 1999, 1998, and 1997,
respectively.  The  convertible  subordinated  note was  converted  into 827,375
shares of common stock of the Company in January 1998.

Income Taxes

        Deferred  income taxes are  accounted  for under the asset and liability
method.  Deferred tax assets and  liabilities  reflect the estimated  future tax
consequences  attributable  to  tax  benefit  carryforwards  and  to  "temporary
differences"  between amounts of assets and liabilities for financial  reporting
purposes  and such  amounts as  measured  by tax laws.  A  valuation  reserve is
established  if it is more likely than not that all or a portion of the deferred
tax asset will not be realized.

        Net  operating  losses of the  Company  incurred  while  operating  as a
division of Sepracor are not  available for  carryforward  because the Company's
results  for  those  periods  were  included  in the tax  returns  of  Sepracor.
Additionally,  based  upon the  Internal  Revenue  Code and  changes  in company
ownership,  utilization of the Company's net operating loss may be subject to an
annual limitation.

Comprehensive Income

        For all periods presented,  net income and comprehensive  income are the
same due to the realization of all previously unrealized gains and losses in the
statement of operations.

New Accounting Standards

        In June 1998, the Financial  Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133 (SFAS 133), "Accounting for Derivative
Instruments and Hedging Activities." This statement  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 statement requires companies to
recognize all derivatives as either assets or liabilities,  with the instruments
measured  at fair value.  The  accounting  for  changes in fair value,  gains or
losses  depends  on the  intended  use  of  the  derivative  and  its  resulting
designation.  The statement is effective for all fiscal quarters of fiscal years

beginning after June 15, 2000. The Company does not expect such adoption to have
a material impact on its financial statements.

Use of Estimates in the Preparation of Financial Statements

        The  preparation  of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of contingent  assets and  liabilities  at December 31, 1999 and 1998
and the  reported  amounts of  revenues  and  expenses  during  the years  ended
December  31,  1999,  1998 and 1997.  Actual  results  could  differ  from those
estimates.

C.      AGREEMENTS WITH SEPRACOR:

        The Company was formerly a  wholly-owned  subsidiary of Sepracor.  As of
January 31, 2000, Sepracor owned 27% of the common stock, $.01 par value, of the
Company (the "Common Stock").

        Under a Technology Transfer and License Agreement,  Sepracor transferred
to the Company all technology  owned or controlled by Sepracor,  including trade
secrets,  patents  and  patent  applications,  that  relates  to and is  used in
researching,  developing  or  manufacturing  products  in the  Company  Field as
defined in the agreement.  Further, Sepracor granted an exclusive license to the
Company  for  any  improvements  to  the  transferred  technology,   which  were
developed, or otherwise acquired, by Sepracor during the period beginning on the
date of the  Technology  Transfer and License  Agreement and  terminating on the
earlier of January 1, 1998 or the  acquisition  of Sepracor or the Company  (the
"Effective Period"). The Company granted to Sepracor an exclusive license to the
transferred  technology  for the  development,  manufacture,  use or sale of any
products  within  the  field of chiral  synthesis,  chiral  separations  and the
development,   manufacture,  use  or  sale  of  chiral  drugs  and  chiral  drug
intermediates,  as well as a non-exclusive license to the transferred technology
for the  development,  manufacture,  use or sale of any products  outside of the
Company Field. All licenses were royalty-free. Sepracor also granted the Company
a right of first  refusal to any product,  which  Sepracor  proposed to sell, or
license a third party to sell during the  Effective  Period,  for use within the
Company Field.

        In addition,  beginning in April 1998,  Sepracor was entitled to certain
rights with respect to the  registration  under the  Securities  Act of 1933, as
amended,  of a  total  of  3,000,000  shares  of  common  stock  related  to the
technology  transfer  and  establishment  of the Company in 1993.  These  rights
provide that  Sepracor may require the Company,  on two  occasions,  to register
shares having an aggregate  offering  price of at least  $5,000,000,  subject to
certain conditions and limitations.

        In September 1998, the Company  obtained a $5 million  revolving line of
credit arrangement with a commercial bank. Sepracor has guaranteed  repayment of
amounts  borrowed under the line of credit.  In exchange for the guarantee,  the
Company granted to Sepracor  warrants to purchase up to 1,700,000  shares of the
Company's  common stock at a price of $0.69 per share.  The warrants will expire
in the year 2003 and have certain registration rights associated with them. (See
Note H)

        In March 1999, the Company completed a private placement  financing with
Sepracor in which the Company  received  $2,000,000  in exchange  for  1,333,334
shares of the  Company's  common  stock and  warrants to purchase an  additional
667,000  shares of common stock at $1.50 per share.  The warrants will expire in
the year 2004 and have certain  registration  rights  associated  with them.  In
certain  circumstances,  the Company is entitled to require Sepracor to exercise
these warrants.


D.      ACCOUNTS RECEIVABLE:

        The  Company's  1999  and 1998  trade  receivables  primarily  represent
amounts due for product  sales.  The allowance for doubtful  accounts was $5,000
and $7,000 at December 31, 1999 and 1998, respectively.

        The Company  performs  ongoing  credit  evaluations of its customers and
generally does not require collateral.

                                            ======           ======
Lease Obligations

        The Company  leased certain  laboratory,  research and office space from
Sepracor  through 1995. In 1995, the Company executed a lease for these facility
requirements,  which  commenced in February  1996 and extends  through  February
2004. The lease provides for two five-year  renewal options.  Under the terms of
the lease,  the  Company is  required  to pay its  allocated  share of taxes and
operating costs in addition to the base annual rent.

        In 1994, the Company,  in collaboration with Sepracor and certain of its
other subsidiaries,  executed an equipment leasing arrangement that provided for
a total of  $2,000,000  to these  companies  for purposes of  financing  capital
equipment.  In October 1996, the Company executed a separate follow-on equipment
leasing  arrangement  that provided  $1,100,000 of equipment  financing  through
March 31, 1997. The Company has leased  various  laboratory,  manufacturing  and
computer  equipment under  noncancelable  capital leases.  Terms of arrangements
with the leasing company contain bargain  purchase  provisions at the expiration
of the lease term,  which range from 36 months to 42 months.  In some instances,
the Company is required to make a deposit of 20% of the original equipment cost,
which  earns  interest  at an annual  rate of 4%. As of  December  31,  1999 the
Company  had  $68,000 on  deposit  at the  leasing  company  under this  leasing
arrangement.  Under  certain  circumstances,  Sepracor is the  guarantor of debt
incurred to acquire  equipment under the leasing  facilities.  The interest rate
charged on the Company's capital leases ranges from 14% to 21%.

Based on the  borrowing  rates  currently  available  to the Company for capital
leases  with  similar  terms and average  maturities,  the fair value of capital
leases approximates the carrying value.

        The total charged to rent expense for all noncancelable leases including
amounts  for  building  maintenance,  utilities  and other  operating  costs was
$660,000, $833,000, and $803,000, in 1999, 1998, and 1997, respectively.

        In  December  1999,  the  Company entered into an  exclusive   five-year
manufacturing  and supply  agreement with a major supplier of a component to the
Company's  product.  The agreement  contains  minimum  purchase  requirements in
future  years,  which if not met could  require the Company to purchase  certain
production equipment of the supplier as defined in the agreement.  The supplier,
under certain  conditions  will acquire such equipment  during fiscal years 2000
and 2001. The agreement also contains provisions under which the agreement could
become  non-exclusive  under certain  conditions as defined in the agreement and
for extensions of the term of the agreement.

        In March 1997, the Company exercised its right, under the lease, to have
a portion of its  leasehold  improvements  financed  and  received  $140,000  in
connection with this arrangement. This amount will be repaid in 60 equal monthly
installments with an interest rate of 12% per annum.

        In September 1998, the Company  completed a $5 million revolving line of
credit  arrangement  with a commercial bank. As of December 31, 1999, the entire
$5 million was outstanding  under the line. The revolving line of credit,  which
expires in August  2000,  is being used to help  finance the  Company's  working
capital requirements and for general corporate purposes.  Amounts borrowed under
the line bear  interest  at the  bank's  prime  lending  rate plus 1/2%  payable
monthly in arrears.  The weighted  average  borrowing  rate for the period ended
December 31, 1999 was 8.67%. For the period ended December 31, 1999, the Company
recorded interest expense related to borrowings under the line of $434,000.  The
credit agreement  contains  customary  covenants and provisions.  The bank has a
first lien on all assets of the Company including its intellectual property.

        Sepracor,  the Company's  largest  shareholder,  has guaranteed to repay
amounts  borrowed under the line of credit.  In exchange for the guarantee,  the
Company granted to Sepracor  warrants to purchase up to 1,700,000  shares of the
Company's  common stock at a price of $0.69 per share.  The warrants will expire
in the year 2003 and have  certain  registration  rights  associated  with them.
HemaSure has placed a value of $1,938,000  on the  1,700,000  warrants as of the
date of the final agreement and is amortizing this deferred  financing charge on
a monthly  basis  over the term of the line of  credit.  For the  periods  ended
December  31,  1999 and 1998 the  Company  amortized  $1,024,000  and  $189,000,
respectively,  of this  deferred  finance  charge and  recorded  it as  interest
expense in the Statement of Operations.

I.      CONVERTIBLE SUBORDINATED NOTE PAYABLE

        In May 1996,  the  Company  acquired  the  plasma  product  unit of Novo
Nordisk  A/S,  a  Denmark  corporation  ("Novo  Nordisk"),  through  its  Danish
subsidiary, HemaSure A/S (the "Denmark Acquisition"). The purchase price for the
transaction  was comprised of a combination  of  promissory  notes,  convertible
subordinated  notes  (which  would  convert to common  stock of the Company or a
subsidiary of the Company) and additional  consideration payable in 1998 in cash
or stock,  at the  option of the  Company,  which  would not be paid in  certain
events.  On  February  20,  1997,  the  Company's  board of  directors  voted to
discontinue  the  development  and  operation  of the  Danish  Plasma  Business,
retroactive to December 31, 1996.

        In January 1997, the Company entered into a  Restructuring  Agreement of
the debt  related to the  Denmark  Acquisition.  Pursuant  to the  Restructuring
Agreement,  approximately  $23,000,000 of indebtedness  owed to Novo Nordisk was
restructured  by way of  issuance  by  the  Company  to  Novo  Nordisk  of a 12%
convertible   subordinated   promissory   note  in  the   principal   amount  of
approximately $11,700,000,  which was due and payable on December 31, 2001, with
interest payable quarterly  (provided that up to approximately  $3,000,000 would
be forgiven in certain circumstances). Approximately $8,500,000 of the reduction
of such indebtedness was forgiven.  The remainder of the reduction represented a
net  amount  due from Novo  Nordisk to the  Company  related to various  service
arrangements between the two companies. The amount included in the balance sheet
at December 31, 1997 included the effect of the  Restructuring  Agreement net of
the  $3,000,000  contingency  amount to reflect the most probable  result of the
Company's  decision to exit the plasma  business.  In December 1997, the Company
notified  the  holder of the note of its  intent to  convert  in  January  1998,
$8,687,000 of debt,  which it believes was the entire amount  outstanding  as of
the date of  conversion.  On January 6, 1998,  the Company  converted  the note,
pursuant to its terms,  into  shares of common  stock at a  conversion  price of
$10.50 per share,  or 827,375  shares.  The holder of the note has contested the
conversion of the note,  including the forgiveness of the $3,000,000 amount. The
Company believes that such assertions are without merit.

K.      STOCKHOLDERS' EQUITY (DEFICIT)

        In March 1999, the Company completed a private placement  financing with
Sepracor in which the Company  received  $2,000,000  in exchange  for  1,333,334
shares of the  Company's  common  stock and  warrants to purchase an  additional
667,000  shares of common stock at $1.50 per share.  The warrants will expire in
the year 2004 and have certain  registration  rights  associated  with them.  In
certain  circumstances,  the Company is entitled to require Sepracor to exercise
these warrants.

        On May 3, 1999, the Company completed a private placement financing with
Gambro Inc.  ("Gambro").  The stock  subscription  agreement,  which the Company
entered into with Gambro Inc. in connection with this financing, provided for an
initial investment of $9,000,000 in exchange for 4,500,000 shares of the Company
common stock. The stock subscription agreement also provided Gambro Inc. with an
option to purchase  additional shares of the Company's common stock for up to an
aggregate  purchase  price of $3,000,000 at any time between  August 3, 1999 and
May 3, 2000 with the price per share of common stock to be based upon the market
price of the Company's common stock. In October 1999, Gambro Inc. exercised this
option in full.  In  connection  with the exercise of this  option,  Gambro Inc.
purchased  498,355 shares at a price of $6.02 per share. The price and number of
shares  reflected the average price of the Company's  stock in the 30 days prior
to the exercise date of October 5, 1999.

L.      STOCK OPTION PLANS

        Statement of Financial  Accounting  Standards No. 123,  "Accounting  for
Stock-Based  Compensation"  (SFAS No.  123),  encourages,  but does not  require
companies to record  compensation  cost for  stock-based  employee  compensation
plans at fair  value.  The  Company  has  chosen  to  continue  to  account  for
stock-based   compensation  using  the  intrinsic  value  method  prescribed  in
Accounting  Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to
Employees,"  and related  interpretations.  Accordingly,  compensation  cost for
stock  options is measured as the excess,  if any, of the quoted market price of
the  Company's  stock at the date of the grant over the amount an employee  must
pay to acquire the stock.

        The Company has two stock options plans  currently in effect under which
future  grants may be issued:  the 1994 Stock Option Plan,  as amended,  and the
1994 Director Option Plan, as amended  (collectively,  the "Plans").  A total of
3,000,000  shares have been  authorized  by the Company for grants of options or
shares,  of which 155,000 are still  available for grant.  Stock options granted
during 1999 and 1998 generally have a maximum term of ten years and vest ratably
over a period of two to five years.

</TABLE>

        The weighted  average grant date fair value for options  granted  during
1999,  1998 and 1997 was $3.27,  $0.49 and $2.04 per option,  respectively.  The
fair  value  of  these  options  at  date  of  grant  was  estimated  using  the
Black-Scholes  model with the following  weighted average  assumptions for 1999,
1998  and  1997:  risk-free  interest  rate  of  5.5%;  dividend  yields  of 0%;
volatility  factor of the market price of the Company's common stock of 75%; and
a weighted average expected life of the options of 5.5 years.

        During 1994 and prior to the Company's initial public offering,  options
to purchase  482,000  shares of common stock were granted  under the Plans at an
exercise  price of $2.00 per share.  The estimated fair market value on the date
of grant was $4.00 per  share.  The  Company  recorded  compensation  expense of
$89,000 and $309,000 in 1998 and 1997, respectively, related to these options.

        In January 1998,  the Company  adopted a one time stock option  exchange
program.  Upon  employee  consent,  the program  provides  for the grant to each
employee of a new stock option in exchange for the cancellation of the old stock
option. The new stock option,  granted at fair market value at date of issuance,
will  become  exercisable  for a number of shares of common  stock  equal to the
number of shares covered by the old stock option.

        In 1995, the Company  adopted the 1995 Employee Stock Purchase Plan (the
"Stock Purchase  Plan").  Under the Stock Purchase Plan, an aggregate of 500,000
shares of common  stock may be  purchased by employees at 85% of market value on
the first or last day of each six-month  offering  period,  whichever  is lower,
through   accumulation  of  payroll   deductions  ranging  from  1%  to  10%  of
compensation as defined, subject to certain limitations.  Options were exercised
to purchase 41,071 shares for a total of $117,000 during the year ended December
31, 1999 and 96,695 shares for a total of $88,000 during the year ended December
31, 1998. At December 31, 1999, 291,397 shares of common stock were reserved for
future issuance under the plan.

        Had  compensation  cost  for  the  Company's  stock  option  plans  been
determined  based on the fair value at the grant  date for awards in 1999,  1998
and 1997  consistent with the provisions of SFAS No. 123, the Company's net loss
and net  loss per  share  would  have  been  reduced  to the pro  forma  amounts
indicated  below. The application of SFAS No. 123 to the employee stock purchase
plan would not result in a significant  difference  from reported net income and
earnings per share.

Net loss per share - pro forma - basic and diluted     $  (0.82)      $   (1.40)     $   (1.28)

</TABLE>

        The pro  forma  effect  on net  income  for  1999,  1998 and 1997 is not
representative  of the pro forma effect on net income in future years because it
does not take into  consideration  pro forma  compensation  expense  related  to
grants made prior to 1995 or anticipated future option activity.

        In connection with the initial public  offering,  the Company granted to
the  underwriter  an option to  purchase  217,500  shares of common  stock at an
exercise price equal to 150% of the initial public  offering price or $10.50 and
subject to adjustment in certain  circumstances.  The option was  exercisable at
any time or from time to time after  April 14, 1995 and before  April 14,  1999.
The option was not exercised.

</TABLE>

        Due to the uncertainty  surrounding the realization of the favorable tax
attributes in future tax returns,  the Company has placed a valuation  allowance
against its otherwise recognizable net deferred tax assets.

        The  Company's  statutory  and  effective  tax  rates  were  34% and 0%,
respectively,  for 1999,  1998 and 1997.  The effective tax rate was 0% due to a
net operating  loss and the  non-recognition  of any net deferred tax asset.  At
December  31,  1999,  the Company had federal and state tax net  operating  loss
carryforwards (NOLs) of approximately $73,000,000 and $67,000,000, respectively,
to offset future regular taxable  earnings.  The federal and state NOLs begin to
expire in 2009 and 2000. Approximately $4,000,000 of state NOLs expired in 1999.
The Company has research and  development tax credit of  approximately  $690,000
and $520,000,  respectively, which both begin to expire in 2009. The Company has
a state  investment tax credits  carryforward of  approximately  $20,000,  which
begins to expire in 2000.

N.      AGREEMENTS

        In July 1999, the Company entered into a master purchase  agreement with
the  American  Red Cross that  provides  for the sale of the r\LS  System by the
Company to the  American  Red Cross on  specified  terms.  The  master  purchase
agreement  provides for a  thirty-eight  month term expiring on August 31, 2002,
subject to, among other things, earlier termination by the American Red Cross in
certain  circumstances.  Under the master purchase  agreement,  the American Red
Cross is required to purchase  specified  minimum annual  quantities of the r\LS
System, subject to certain terms and conditions. The term of the master purchase
agreement may be extended by one year in certain  circumstances  if the American
Red Cross fails to meet its minimum purchase obligation in the third year of the
agreement.

     In August 1998, the Company completed an amended and restated Master
Strategic Alliance Agreement with the American Red Cross BioMedical Services,
which provides for, among other things, the development and enhancement of a
number of filtration products, based on the Company's core technology. The
agreement has a term of five years, unless previously terminated, and can be
renewed or extended. In connection with this agreement, the American Red Cross
is eligible to receive warrants to purchase common stock of the Company up to a
maximum of 400,000 shares based on certain milestones and at a price of $1.51
per share, as determined at the date of this agreement.

        In 1998, the Company completed a distribution and development agreement,
which  was  amended  in May  1999,  with  Gambro  Inc.  to act as the  Company's
exclusive  distributor of the Company's r\LS System worldwide,  except for sales
to the  American  Red Cross.  Under the  amended  distribution  and  development
agreement,  Gambro  Inc.  is  required  to  purchase  specified  minimum  annual
quantities  of the  r\LS  System,  subject  to  certain  terms  and  conditions.
Furthermore,  this agreement provides that Gambro Inc. may upon mutual agreement
by the Company and Gambro Inc., distribute  additional future products developed
by us that filter blood and its components.

The  distribution  agreement  provides for a five-year term that expires in June
2004,  subject  to  automatic   three-year  renewals  unless  the  agreement  is
previously terminated.

O.      EMPLOYEES' SAVINGS PLAN

        The Company has a 401(k) plan for all employees. Under the provisions of
the plan,  employees may voluntarily  contribute up to 15% of their compensation
subject to statutory  limitations.  In addition, the Company can make a matching
contribution  at its discretion.  In 1999,  1998 and 1997, the Company  provided
matching contributions of approximately $40,000, $0, and $34,000, respectively.

P.      LITIGATION

        The  Company is a  defendant  in a lawsuit  brought by Pall  Corporation
("Pall")  regarding the LeukoNet System,  which is no longer made or sold by the
Company.  In  a  complaint  filed  in  November  1996,  Pall  alleged  that  the
manufacture,  use and/or sale of the LeukoNet System  infringed upon two patents
held by Pall. Pall dropped its allegations concerning infringement of one of the
patents and alleges  only that the  LeukoNet  System  infringed  the Pall's U.S.
Patent No. 4,952,572 (the "'572 Patent").

        With respect to the allegations  concerning the '572 Patent, the Company
answered the  complaint  stating that the LeukoNet  System does not infringe any
claim  of  the  asserted  patents.   Further,  the  Company  counterclaimed  for
declaratory judgment of invalidity,  noninfringement and unenforceability of the
'572 Patent.  Pall amended its complaint to add Lydall,  Inc.,  whose subsidiary
supplied  the filter  media for the  LeukoNet  System,  as a  co-defendant.  The
Company filed for summary judgment of non-infringement, and Pall cross-filed for
summary judgement of infringement at the same time.  Lydall,  Inc. supported the
Company's  motion for summary judgment of  non-infringement,  and filed a motion
for summary  judgment that the asserted claims of the '572 patent are invalid as
a matter of law.  Discovery has been completed in the action.  The court has not
acted on the summary judgment motions.

        The  Company  and Gambro BCT filed a complaint  for  declaratory  relief
against Pall in the United States  District  Court of Colorado.  The Company and
Gambro BCT seek declaratory  relief that the '572 Patent, the Pall's U.S. Patent
No. 5,451,321 ("'321 Patent") and Pall's U.S. Patent Nos. 5,229,012,  5,344,561,
5,501,795 and  5,863,436  are invalid and not  infringed by the  Company's  r\LS
System and methods of using the r\LS  System.  Pall moved to dismiss or transfer
to the Eastern District of New York, or in the alternative, to stay this action.
The Company and Gambro PCT opposed Pall's  motion.  On July 16, 1999, the United
States  District  Court of Colorado  denied Pall's motion to transfer or, in the
alternative,  to stay the action, and the action is proceeding. On September 30,
1999,  the Court  denied  Pall's  motion to  dismiss  the action and the case is
proceeding.  Pall  submitted  a  counterclaim  alleging  that  the  r\LS  System
infringes  the '572  patent  and that the  Company  and  Gambro  BCT  tortiously
interfered and unfairly  competed with Pall's  business.  Pall has also asserted
that the r\LS System  infringes  one or more of the other  patents  that are the
subject of the lawsuit.

        On April 23, 1999, Pall filed a complaint against the Company and Gambro
BCT in the Eastern  District of New York alleging that the r\LS System infringes
the '572 Patent and that the Company and Gambro BCT  tortiously  interfered  and
unfairly  competed  with Pall's  business.  On May 19,  1999,  Pall  amended its
complaint and added Gambro Inc., Gambro A.B., a Swedish company, of which Gambro
Inc. is a business unit, and Sepracor as defendants.  The Company and Gambro BCT
have moved to  dismiss,  transfer  or stay the action and Pall has  opposed  the
motion.  There has been no decision on the motion.

        The  Company  has  engaged  patent  counsel to  investigate  the pending
litigations.  The Company believes, based upon its review of these matters, that
a properly informed court should conclude that the manufacture,  use and/or sale
by the Company or the its  customers of the LeukoNet  System and the r\LS System
do not infringe any valid enforceable claims of the Pall patents. However, there
can be no assurance  that the Company  will prevail in the pending  litigations,
and an adverse outcome in a patent infringement action would have a material and
adverse  effect on the Company's  financial  condition  and future  business and
operations,  including the possibility of significant damages in the litigations
and an  injunction  against the sale of the r\LS System if the Company  does not
prevail in the litigations.

        A prior lawsuit brought by Pall in February 1996 has concluded.  In June
1999, the United States Court of Appeals for the Federal Circuit determined that
the LeukoNet  System did not  infringe  claim 39 of the '321 Patent and Pall has
not appealed that decision.
