1.         Basis of Presentation

           The  accompanying  financial  statements  are unaudited and have been
           prepared  on  a  basis  substantially  consistent  with  the  audited
           financial statements.

           Certain information and footnote disclosures normally included in the
           Company's  annual  statements  have been  condensed  or omitted.  The
           condensed interim financial statements, in the opinion of management,
           reflect  all  adjustments   (including  normal  recurring   accruals)
           necessary for a fair statement of the results for the interim periods
           ended March 31, 1999 and 1998.

           The results of operations for the interim periods are not necessarily
           indicative of the results of operations to be expected for the fiscal
           year.  These  interim   financial   statements   should  be  read  in
           conjunction with the audited financial  statements for the year ended
           December 31, 1998,  which are  contained  in the  Company's  Form 10K
           (File No. 0-23776), filed with the Securities and Exchange Commission

4.         Convertible subordinated note payable

           In January 1997, the Company entered into a  Restructuring  Agreement
           of the debt  related  to its  acquisition  of Novo  Nordisk's  plasma
           products unit.  The amount  included in the balance sheet at December
           31, 1997

           includes  the  effect  of  the  Restructuring   Agreement  net  of  a
           $3,000,000  contingency amount to reflect the most probable result of
           the  Company's  decision to exit the plasma  business.  On January 6,
           1998,  $8,687,000 of debt,  which the Company believes was the entire
           amount  outstanding as of the date of conversion,  was converted into
           Common  Stock at a conversion  price of $10.50 per share,  or 827,375
           shares, pursuant to the terms of the note. The holder of the note has
           contested the  conversion of the note,  including the  forgiveness of
           the $3,000,000 amount.

5          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 common stock of the Company and warrants to
           purchase and  additional  667,000 shares of common stock at $1.50 per
           share.  The  warrants  expire  in the  year  2004  and  have  certain
           registration  rights associated with them. In certain  circumstances,
           HemaSure may require Sepracor to exercise these warrants.

6.         Net loss per share

           The net loss per  share is based on the  weighted  average  number of
           common stock outstanding during the period.  Common Share equivalents
           are not  included  in the per share  calculation  where the effect of
           their inclusion would be  antidilutive.  Common Share  equivalents of
           the Company consists of common stock warrants and stock options.  The
           Company had 5,519,028 and 2,889,420 Common Share equivalents at March
           31, 1999 and 1998, respectively.


7.         Litigation

           The  Company  is  a  defendant  in  two  lawsuits   brought  by  Pall
           Corporation  ("Pall")  on  its  LeukoNet  Prestorage   Leukoreduction
           Filter, which is no longer made or sold by the Company. In complaints
           filed in February  1996 and  November  1996,  Pall  alleged  that the
           Company's  manufacture,  use  and/or  sale  of the  LeukoNet  product
           infringes upon three patents held by Pall.

           On October 14, 1996, in connection  with the first action  concerning
           U.S. Patent No.  5,451,321 (the "'321  Patent"),  the Company filed a
           motion for summary  judgment of  noninfringement.  Pall filed a cross
           motion for summary judgment of infringement at the same time.

           In October  1997,  the Eastern  District of New York  granted in part
           Pall's  summary  judgment  motion and held that the LeukoNet  product
           infringes  a single  claim  from the '321  patent.  The  Company  has
           terminated  the  manufacture,  use,  sale and  offer  for sale of the
           filter  subject to the court's  order.  The Company has  appealed the
           October  1997  decision  to the  Court  of  Appeals  for the  Federal
           Circuit.  Oral arguments were heard in February 1999. The Company now
           waits for a decision from the Federal  Circuit.  Remaining  discovery
           relating to the damages phase of the first action has been completed.

           With  respect  to the  second  action  concerning  U.S.  Patent  Nos.
           4,952,572 (the "'572 patent") and 4,340,479 (the "'479 patent"),  the
           Company has answered the complaint  stating that it does not infringe
           any  claim  of  the  asserted  patents.   Further,  the  Company  has
           counterclaimed    for    declaratory    judgment    of    invalidity,
           noninfringement  and  unenforceability  of the '572 and '479 patents.
           Pall has amended its Complaint to add Lydall,  Inc. whose  subsidiary
           supplied filter media for the LeukoNet product, as a co-defendant and
           has dropped its claims that the LeukoNet  product  infringes the '479
           patent.   The   Company   has   filed   for   summary   judgment   of
           non-infringement,  and Pall has cross-filed  for summary  judgment of
           infringement at the same time.  Lydall supported the Company's motion
           for summary judgment of non-infringement,  and has 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.

           On April 5, 1999,  the Company and COBE BCT,  Inc.  filed a complaint
           for  declaratory  relief  against Pall in the U.S.  District Court of
           Colorado. The Company and COBE BCT, Inc. seek declaratory relief that
           Pall's U.S. patent No's. 4925,572, 5,229,012,  5,344,561,  5,451,321,
           5,501,795  and  5,863,436  are  invalid

           and not infringed by the  Company's  r\LS filter and methods of using
           the r\LS filter. No response has been filed.

           On April 23, 1999 Pall filed a complaint against the Company and COBE
           BCT,  Inc.  in  the  Eastern  District  of  New  York  alleging  that
           HemaSure's  r\LS  filter  infringes  Pall's '572  patent,  tortuously
           interfered and unfairly  competed with Pall's business.  HemaSure was
           served with the complaint on April 30, 1999.

           The Company believes,  based on advice of its patent counsel,  that a
           properly  informed court should  conclude that the  manufacture,  use
           and/or sale by the Company or its  customers of the LeukoNet  product
           and the r\LS filter did not infringe any valid enforceable  claims of
           the Pall patents.  The Company also believes,  based on advice of its
           patent counsel,  that a properly  informed court should conclude that
           the  manufacture,  use and/or sale by the Company or its customers of
           the r\LS filter 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  adverse effect on
           the Company's financial condition and future business and operations.

8.         Subsequent Event

           On May 3, 1999, the Company completed a private  placement  financing
           with  COBE  Laboratories,  Inc.  ("COBE").  The  financing  agreement
           provides  for an initial  investment  of  $9,000,000  in exchange for
           4,500,000  shares of the Company's  common stock.  The agreement also
           provides COBE with an option to purchase an additional  $3,000,000 of
           common  stock of the Company at any time  between  August 3, 1999 and
           May 3, 2000. Should COBE exercise its option, the number of shares to
           be issued will be based on the average closing price of the Company's
           common stock for the  thirty-day  period prior to the  exercise.  The
           financing  agreement  provides that COBE will have  representation on
           the Company's  Board of Directors and its  representative  committees
           and  contains  among other  things  various  registration  rights and
           anti-dilution and standstill provisions customary in such agreements.

           In connection  with the financing,  the Company  completed an Amended
           and Restated Exclusive  Distribution Agreement with COBE. The amended
           distribution  agreement  expands  the  territory  in which  COBE will
           distribute  the Company's  products to make it  worldwide,  excluding
           sales to the American Red Cross. In addition,  the agreement provides
           for joint  efforts  related  to the  defense of  HemaSure's  products
           against intellectual property claims made by third parties. As in the
           original  agreement,  there is a  provision  for the  development  of
           additional  products to be  incorporated  by COBE into its  automated
           blood component equipment.

Item 2.                Management's Discussion and Analysis
                of Financial Condition and Results of Operations.


Results of Operations

Overview

HemaSure  was  established  in December  1993 as a wholly  owned  subsidiary  of
Sepracor Inc. ("Sepracor").  The Company is utilizing its proprietary filtration
technologies to develop  products to increase the safety of donated blood and to
improve  certain  blood  transfusion  procedures.  The  Company's  products  are
designed for use in blood centers and hospital blood banks worldwide.

In June 1995 the Company received 510(K) premarket  notification  clearance from
the  United  States  Food  and  Drug  Administration  for its  first  generation
leukoreduction system, the LeukoNet Pre-Storage Leukoreduction System ("LeukoNet
System") and began commercialization of this product in the second half of 1995.
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,  the r\LS
System.  In  May  1998,  the  Company  filed  a  510(K)  premarket  notification
application for the r\LS System. The Company began accepting orders for the r\LS
outside  of the U.S.  in the first  quarter  1999.  All of the  Company's  other
planned  blood-related  products are in the research and development  state, and
certain of these products may require  preclinical and clinical testing prior to
submission  of any  regulatory  application  for  commercial  use. The Company's
success  will  depend  on  development   and  commercial   acceptance  of  these
blood-related products.

The  Company  is  subject  to risks  common to small  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,  access to sources of capital,  protection of proprietary  technology
and compliance with FDA regulations.

Three months ended and 1998 Revenues were $4,000 for the quarter ended  compared
to $25,000  in the same  period in 1997.  Revenues  for the first  quarter  1998
represent the sale of the  Company's  LeukoNet  System.  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.  Revenues for the first quarter 1999 represent the sale
of the Company's r\LS System outside of the U.S.

Total cost of products sold  exceeded  total product sales in all periods due to
the high costs associated with low volume production.

Research and  development  expenses  were  $524,000 in the first quarter of 1999
compared  to $762,000 in the first  quarter of 1998.  The  decrease in the three
month period is primarily  attributable  to a lower level of  development  costs
associated  with  the  development  of the r\LS  System  as the  Company  awaits
clearance of this product by the FDA.

Legal  expenses  related to patents were  $840,000 in the first  quarter of 1999
compared  to  $1,062,000  in the  first  quarter  of  1998.  The  costs  in both
three-month periods are primarily associated with defending the Company's patent
position in its outstanding litigation with Pall Corp.

Selling,  general and administrative  expenses were $849,000 in the three months
ended  compared to  $1,011,000  in the three months  ended March 31,  1998.  The
decrease in the three-month period is primarily  attributable to lower sales and
marketing  costs  associated  with  the  Company's  decision  to  focus  on  the
development  of the r\LS  filter.  The  Company  expects  that  such  sales  and
marketing  costs  will  increase  upon  anticipated  increases  in  sales of its
products.

Interest  income for the  quarter  ended of $11,000  decreased  compared  to the
quarter ended March 31, 1998 of $74,000 due to lower average cash and marketable
securities  balances available for investment.  Interest expense

835307.2
                                        7

<PAGE>

for the quarter ended of $385,000  increased compared to the quarter ended March
31, 1998 of $36,000 related to a note payable which was not in existence  during
the first  quarter  1998  offset by a lower  average  capital  lease  obligation
balance.

Liquidity and Capital Resources

The net  decrease in cash and cash  equivalents  for the three  months ended was
$872,000.  This decrease is attributable primarily to net cash used in operating
activities  of $2,767,000  and net cash used in investing  activities of $48,000
offset in part by net cash provided from financing activities of $1,943,000.

Net cash used in operating activities is primarily  attributable to the net loss
of $2,918,000 and a decrease in accounts payable and accrued expense balances of
$267,000,  offset in part by  financing  costs  related to warrants of $256,000,
depreciation  and  amortization of $97,000 and lower prepaid expense balances of
$62,000.  Net cash  provided  from  financing  activities  relates  primarily to
proceeds from the issuance of common stock of $2,000,000 in March 1999.

In January 1997, the Company entered into a Restructuring  Agreement of the debt
related to its  acquisition of Novo Nordisk's  plasma  products unit. The amount
included in the balance  sheet at December  31, 1997  includes the effect of the
Restructuring  Agreement net of a $3,000,000  contingency  amount to reflect the
most probable result of the Company's  decision to exit the plasma business.  On
January 6, 1998,  $8,687,000 of debt,  which the Company believes was the entire
amount outstanding as of the date of conversion, was converted into Common Stock
at a conversion  price of $10.50 per share, or 827,375  shares,  pursuant to the
terms of the note.  The holder of the note has contested  the  conversion of the
note, including the forgiveness of the $3,000,000 amount.

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
common  stock of the Company 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, HemaSure may require Sepracor to exercise these warrants.

On May 3, 1999, the Company completed a private  placement  financing with COBE.
The  financing  agreement  provides for an initial  investment  of $9,000,000 in
exchange for 4,500,000  shares of the Company's common stock. The agreement also
provides  COBE with an option to purchase  an  additional  $3,000,000  of common
stock of the Company at any time between August 3, 1999 and May 3, 2000.  Should
COBE exercise its option, the number of shares to be issued will be based on the
average  closing price of the Company's  common stock for the thirty-day  period
prior to the  exercise.  The  financing  agreement  provides that COBE will have
representation  on the  Company's  Board  of  Directors  and its  representative
committees and contains,  among other things,  various  registration  rights and
anti-dilution and standstill provisions customary in such agreements.

The Company  believes,  based on its current  operating  plan,  that its current
available cash balances together with the private placement  financing completed
in May 1999 with COBE will be  sufficient to fund its  operations  into the year
2000. The Company's cash requirements may vary materially from those now planned
because  of factors  such as  successful  development  of  products,  results of
product  testing,  approval  process at the FDA and  similar  foreign  agencies,
commercial acceptance of its products,  patent developments and the introduction
of competitive products.

Readiness for Year 2000

          The "Year 2000" issue  results  from the use in computer  hardware and
software of two digits  rather than four digits to define the  applicable  year.
When computer  systems must process dates both before and after January 1, 2000,
two-digit year "fields" may create processing  ambiguities that can cause errors
and system failures. The results of these errors may range from minor undetected
errors to complete shutdown of an affected system.  These errors or failures may
have  limited  effects,  or the  effects  may be  widespread,  depending  on the
computer chip, system or software, and its location and function. The effects of
the Year 2000 problem are exacerbated because of the interdependence of computer
and  telecommunications  systems in the United States and  throughout the world.
Because  of this  interdependence,  the  failure  of one  system may lead to the
failure of many other systems even though

835307.2
                                        8

<PAGE>

the other systems are themselves "Year 2000 compliant." The Company has reviewed
the Year 2000 issue as it may affect the Company's business activity.

          The Company is a  developer  and  supplier of medical  devices for the
blood  transfusion  industry.  Currently,  the  Company  has  only  one  product
available  for sale  outside of the United  States and is awaiting  approval for
sale in the United  States.  The Company is reliant on a small number of vendors
to supply the critical  components  for making this product,  but has identified
alternative suppliers as a contingency plan. Only final assembly of this product
is done at the Company's  Marlborough,  MA facility. The Company sells primarily
to  blood  centers  and  hospital  blood  banks  and  through  an  international
distributor, and therefore there are a limited number of customers. For internal
systems,  the Company uses  standardized  software  from large  well-established
software  providers  on PCs for  inventory  management,  financial  systems  and
general communications purposes.

          The Company has  implemented  a Year 2000 plan (the  "Plan")  which is
designed  to cover all of the  Company's  activities,  which will be modified as
circumstances  change.  Under  the  Plan,  the  Company  is  using a  five-phase
methodology  for  addressing the issue.  The phases are  Awareness,  Assessment,
Correction,  Validation and Implementation.  A heightened emphasis on completion
will continue  through the second  quarter.  Awareness  consists of defining the
Year 2000 problem and gaining  executive level support and  sponsorship.  A Year
2000 program team has been established and an overall strategy  created.  During
Assessment,  all internal systems,  products and supply chain partners have been
inventoried  and  prioritized  for  renovation.  The  Company  believes  it  has
completed a majority of the Awareness and Assessment  phases,  however,  ongoing
work will be required in these areas as the Company  completes its assessment of
existing supply chain partners and enters into new supply chain relationships in
the ordinary course of business.  Renovation consists of converting,  replacing,
upgrading  or  eliminating  systems  that have Year  2000  problems.  Validation
involves  ensuring that  hardware and software  fixes will work properly in 1999
and beyond and can occur both before and after  implementation.  Validation will
continue  through June 1999 to allow for thorough  testing before the Year 2000.
Implementation is the installation of hardware and software components in a live
environment.

          The   Company  has   completed   the   installation   of  an  upgraded
manufacturing system, which is Year 2000 compliant. Validation of this system is
ongoing.  Installation of its Year 2000 compliant internal communications system
has also been completed.  The Company's  financial  reporting  system is already
Year 2000 compliant. The Company continues to assess all of its internal systems
for operational effectiveness and efficiency beyond Year 2000 concerns.

          The impact of Year 2000 issues on the Company  will depend not only on
corrective actions that the Company takes but also on the way in which Year 2000
issues are addressed by governmental agencies,  business and other third parties
that provide  services or data to, or receive services or data from the Company,
or whose  financial  condition  or  operational  capability  is important to the
Company.  To reduce  this  exposure,  the  Company  has an  ongoing  process  of
identifying  and  contacting  mission-critical  third  party  vendors  and other
significant  third parties to determine  their Year 2000 plans and target dates.
To date,  the  Company is not aware of any  critical  vendors or  customers  who
either are not  addressing the Year 2000 issue or have indicated that there will
be a problem.

          Risks  associated  with any such third  parties  located  outside  the
United States may be higher insofar as it is generally  believed that non-United
States  businesses  may not be addressing  their Year 2000 issues on as timely a
basis as United States businesses.  Notwithstanding the Company's efforts, there
can be no assurance  that the Company,  mission-critical  third party vendors or
other significant third parties will adequately address their Year 2000 issues.

          The Company is  developing  contingency  plans for  implementation  in
event  that  the  Company,   mission-critical   third  party  vendors  or  other
significant  third  parties fail to  adequately  address Year 2000 issues,  Such
plans  principally   involve   identifying   alternative   vendors  or  internal
remediation.  There can be no assurance  that any such plans will fully mitigate
any  such   failures   or   problems.   Furthermore,   there   may  be   certain
mission-critical third parties, such as utilities,  telecommunication companies,
or material  vendors where  alternative  arrangements  or sources are limited or
unavailable.

<PAGE>

          Although it is difficult  to estimate the total costs of  implementing
the Plan,  through June 1999 and beyond, the Company's  preliminary  estimate is
that such  costs will total less than  $100,000.  However,  although  management
believes  its  estimates  are  reasonable,  there can be no  assurance,  for the
reasons stated in the next paragraph,  that the actual costs of implementing the
Plan would not differ  materially  from the  estimated  costs.  The  Company has
incurred  approximately  $30,000  through March 31, 1999 on this project,  which
does not include the costs to re-deploy existing staff.

          The Company does not believe that the  redeployment  of existing staff
will have a material  adverse  effect on its business,  results of operations or
financial  position.  Incremental  expenses related to the Year 2000 project are
not  expected to  materially  impact  operating  results in any one period.  The
extent and  magnitude  of the Year 2000  problem as it will affect the  Company,
both before and for some period after January 1, 2000,  are difficult to predict
or  quantify  for a number  of  reasons.  Among the most  important  are lack of
control  over  systems  that are used by third  parties who are  critical to the
Company's operation,  dependence on third party software vendors to deliver Year
2000 upgrades in a timely manner, complexity of testing inter-connected networks
and  applications  that  depend  on third  party  networks  and the  uncertainty
surrounding  how  others  will deal with  liability  issues  raised by Year 2000
related failures.  There can be no assurance,  for example, that systems used by
third parties will be adequately  remediated so that they are Year 2000 ready by
January  1,  2000,  or by some  earlier  date,  so as not to  create a  material
disruption  to  the  company's  business.   Moreover,  the  estimated  costs  of
implementing  the Plan do not take into account the costs, if any, that might be
incurred  as a result of Year 2000  related  failures  that  occur  despite  the
Company's implementation of the Plan.

          Although the Company is not aware of any material  operational  issues
associated  with  preparing its internal  systems for the Year 2000, or material
issues with respect to the  adequacy of  mission-critical  third party  systems,
there  can be no  assurance  that  the  Company  will  not  experience  material
unanticipated  negative  consequences and/or material costs caused by undetected
errors or defects  in such  systems or by the  Company's  failure to  adequately
prepare for the results of such  errors or defects,  including  costs of related
litigation,  if any.  The  impact of such  consequences  could  have a  material
adverse  effect on the  Company's  business,  financial  condition or results of
operations.  For a more complete discussion of risks and uncertainties involving
the Company's business, please see the risks factors described under the heading
"Factors That May Affect Future Results of Operations."

          Because of the foregoing factors, past financial results should not be
relied upon as an indication of future  performance.  The Company  believes that
period-to-period   comparisons  of  its  financial   results  to  date  are  not
necessarily  meaningful and expects that its results of operations may fluctuate
from period to period in the future. See "-- Overview."

                           PART II - OTHER INFORMATION


Items  1.            Legal Proceedings.

                     The Company is a defendant in two lawsuits  brought by Pall
                     on its LeukoNet Prestorage  Leukoreduction Filter, which is
                     no longer made or sold by the Company.  In complaints filed
                     in February 1996 and November  1996,  Pall alleged that the
                     Company's  manufacture,  use  and/or  sale of the  LeukoNet
                     product infringes upon three patents held by Pall.

                     On October 14, 1996,  in  connection  with the first action
                     concerning the '321 Patent,  the Company filed a motion for
                     summary  judgment  of  noninfringement.  Pall filed a cross
                     motion for  summary  judgment of  infringement  at the same
                     time.

                     In October 1997,  the Eastern  District of New York granted
                     in part Pall's  summary  judgment  motion and held that the
                     LeukoNet  product  infringes  a single  claim from the '321
                     patent.  The Company has terminated the  manufacture,  use,
                     sale  and  offer  for  sale of the  filter  subject  to the
                     court's  order.  The Company has  appealed the October 1997
                     decision to the Court of Appeals  for the Federal  Circuit.
                     Oral arguments were heard in February 1999. The Company now
                     waits for a decision  from the Federal  Circuit.  Remaining
                     discovery relating to the damages phase of the first action
                     has been completed.

                     With  respect  to the  second  action  concerning  the '572
                     patent and the '479  patent,  the Company has  answered the
                     complaint  stating  that it does not  infringe any claim of
                     the   asserted   patents.    Further,   the   Company   has
                     counterclaimed  for  declaratory  judgment  of  invalidity,
                     noninfringement  and  unenforceability of the '572 and '479
                     patents. Pall has amended its Complaint to add Lydall, Inc.
                     whose  subsidiary  supplied  filter  media for the LeukoNet
                     product,  as a co-defendant and has dropped its claims that
                     the LeukoNet product infringes the '479 patent. The Company
                     has filed for  summary  judgment of  non-infringement,  and
                     Pall has cross-filed  for summary  judgment of infringement
                     at the same time. Lydall supported the Company's motion for
                     summary  judgment  of  non-infringement,  and  has  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.

                     On April 5, 1999,  the Company and COBE BCT,  Inc.  filed a
                     complaint for  declaratory  relief against Pall in the U.S.
                     District Court of Colorado.  The Company and COBE BCT, Inc.
                     seek  declaratory  relief  that Pall's  U.S.  patent  No's.
                     4,925,572,  5,229,012,  5,344,561, 5,451,321, 5,501,795 and
                     5,863,436  are invalid and not  infringed by the  Company's
                     r\LS  filter  and  methods  of using  the r\LS  filter.  No
                     response has been filed.

                     On April  23,  1999  Pall  filed a  complaint  against  the
                     Company and COBE BCT,  Inc. in the Eastern  District of New
                     York alleging that HemaSure's r\LS filter  infringes Pall's
                     '572 patent,  tortuously  interfered and unfairly  competed
                     with  Pall's  business.  The  Company  was served  with the
                     complaint on April 30, 1999.

                     The  Company  believes,  based  on  advice  of  its  patent
                     counsel,  that a properly  informed  court should  conclude
                     that the manufacture, use and/or sale by the Company or its
                     customers  of the  LeukoNet  product and the r\LS filter do
                     not  infringe  any  valid  enforceable  claims  of the Pall
                     patents. The Company also believes,  based on advice of its
                     patent  counsel,  that a  properly  informed  court  should
                     conclude  that  the  manufacture,  use  and/or  sale by the
                     Company or its customers of the r\LS filter 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 adverse effect on
                     the Company's  financial  condition and future business and
                     operations.

Items  2.            Changes in Securities and Use of Proceeds.

                     On  March  23,  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
                     common  stock of the  Company  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,  HemaSure  may require  Sepracor to
                     exercise these warrants.

                     On May 3, 1999, the Company  completed a private  placement
                     financing  with COBE,  who is an  accredied  investor.  The
                     financing  agreement  provides for an initial investment of
                     $9,000,000  in  exchange  for   4,500,000   shares  of  the
                     Company's  common stock.  The agreement  also provided COBE
                     with an option to purchase,  subject to certain conditions,
                     an additional  $3,000,000 of common stock of the Company at
                     any time between August 3, 1999 and May 3, 2000. The number
                     of shares to be issued will be based on the average closing
                     price of the  Company's  common  stock  for the  thirty-day
                     period prior to the exercise.

                     In each case set forth in this Item 2, the securities  were
                     issued  pursuant  to  exemptions   from  the   registration
                     requirements  of the  Securities  Act of 1933,  as amended,
                     under Section 4(2).

Purchaser is a corporation duly organized, validly existing and in good standing
under the laws of the State of Colorado. The Purchaser has all necessary
corporate power and authority to enter into this Agreement and the other
Alliance Agreements to which it is a party, to carry out its obligations
hereunder and thereunder and to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement and the other Alliance
Agreements by the Purchaser, the performance by the Purchaser of its obligations
hereunder and thereunder and the consummation by the Purchaser of the
transactions contemplated hereby and thereby have been duly authorized by all
requisite action on the part of the Purchaser. This Agreement and the other
Alliance Agreements have been duly executed and delivered by the Purchaser, and
(assuming due authorization, execution and delivery by the Company) constitute
legal, valid and binding obligations of the Purchaser enforceable against the
Purchaser in accordance with their terms, except as may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights and general principles of
equity.

         SECTION 4.02. No Conflict. Assuming the making and obtaining of all
filings, notifications, consents, approvals, authorizations and other actions
referred to in Section 4.03, except as may result from any facts or
circumstances relating solely to the Company, the execution, delivery and
performance of the Alliance Agreements by the Purchaser does not and will not
(a) violate, conflict with or result in the breach of any provision of the
certificate of incorporation or by-laws of the Purchaser, (b) conflict with or
violate any Law or Governmental Order applicable to the Purchaser or (c)
conflict with, or result in any breach of, constitute a default (or event which

under, require any consent under, or give to others any rights of termination,
amendment, acceleration, suspension, revocation, or cancellation of, or result
in the creation of any Encumbrance on any of the assets or properties of the
Purchaser pursuant to, any note, bond, mortgage or indenture, contract,
agreement, lease, sublease, license, permit, franchise or other

                                       17

instrument or arrangement to which the Purchaser is a party or by which any of
such assets or properties are bound or affected which, with respect to clauses
(b) and (c) above would have a material adverse effect on the ability of the
Purchaser to consummate the transactions contemplated by the Alliance
Agreements.

         SECTION 4.03. Governmental Consents and Approvals. The execution,
delivery and performance of the Alliance Agreements by the Purchaser do not and

for its own account solely for the purpose of investment and not with a view to,

Restrictions. The Purchaser understands that the Shares have not been and will
not be registered under the Securities Act or under any state securities laws
(other than in accordance with the Stockholder's Agreement) and are being
offered and sold in reliance upon federal and state exemptions for transactions
not involving any public offering and that the Shares have not been approved or
disapproved by the SEC or by any other federal or state agency. The Purchaser
further understands that such exemption depends in part upon, and such Shares
are being sold in reliance on, the representations and warranties set forth in
this Article IV. The Purchaser understands that (i) none of the Shares may be
sold, transferred or assigned unless registered by the Company pursuant to the
Securities Act and any applicable state securities laws, or unless an exemption
therefrom is available, and, accordingly, it may not be possible for the
Purchaser to liquidate its investment in the Shares, and it agrees not to sell,
assign or otherwise transfer or dispose of any Shares unless such Shares have
been so registered or an exemption from registration is available, and (ii) the
Shares are subject to certain restrictions on transfer and voting, as set forth
in the Stockholder's Agreement.

         SECTION 4.06. Sophistication and Financial Condition of Purchaser. The
Purchaser represents and warrants to the Company that it is an "Accredited
Investor" as defined in Regulation D under the Securities Act and that it
considers itself to be an experienced and sophisticated investor and to have
such knowledge and experience in financial and business matters as are necessary
to evaluate the merits and risks of an investment in the Shares. The Purchaser
also represents it has not been organized for the sole purpose of acquiring the
Shares. The Purchaser has been furnished access to such information and
documents as it has requested and has been afforded an opportunity to ask
questions of and receive answers from representatives of the Company concerning
the terms and conditions of this Agreement and the purchase of the Shares
contemplated hereby.

         SECTION 4.07. Year 2000 Compliance. The Purchaser has (i) undertaken an
assessment of those Purchaser Systems that could be adversely affected by a
failure to be Year

837579.1

                                       18

Purchaser Systems Year 2000 Compliant. The Purchaser has made available for
review to the Company copies of all material documents related to such
assessment and plan implementation efforts, including communications to and from
customers and material Vendors and suppliers and all plans, time lines and cost
estimates for rendering the Purchaser Systems Year 2000 Compliant. Based on such
review and assessment, all Purchaser Systems are Year 2000 Compliant or will be
Year 2000 Compliant as required to avoid having a material adverse effect on the
Purchaser's ability to perform any of its obligations under the Alliance
Agreements.

other transactions hereby or thereby.

thereof, and containing a reference to the provisions of this Agreement in
respect of which such right of indemnification is claimed or arises. The
obligations and Liabilities of the Indemnifying Party under this Article VI with
respect to Losses arising from claims of any third party which are subject to
the indemnification provided for in this Article VI ("Third Party Claims") shall
be governed by and contingent upon the following additional terms and
conditions: if an Indemnified Party shall receive notice of any Third Party
Claim, the Indemnified Party shall give the Indemnifying Party notice of such
Third Party Claim following receipt by the Indemnified Party of such notice in
the time frame provided above; provided, however, that the failure to provide
such notice shall not release the Indemnifying Party from any of its obligations
under this Article VI except to the extent the Indemnifying Party is materially
prejudiced by such failure and shall not relieve the Indemnifying Party from any
other obligation or Liability that it may have to any Indemnified Party
otherwise than under this Article VI. If the Indemnifying Party acknowledges in
writing its obligation to indemnify the Indemnified Party hereunder against any
Losses that may result from such Third Party Claim, then the Indemnifying Party
shall be entitled to assume and control the defense of such Third Party Claim at
its expense and through counsel of its choice if it gives notice of its
intention to do so to the Indemnified Party within ten days of the receipt of
such notice from the Indemnified Party; provided, however, that if there exists
or is reasonably likely to exist a conflict of interest that would make it
inappropriate in the judgment of the Indemnified Party, in its reasonable
discretion, for the same counsel to represent both the Indemnified Party and the
Indemnifying Party, then the Indemnified Party shall be entitled to retain its
own counsel at the expense of the Indemnifying Party. In the event the
Indemnifying Party exercises the right to undertake any such defense


837579.1

                                       21


against any such Third Party Claim as provided above, the Indemnified Party
shall cooperate with the Indemnifying Party in such defense and make available
to the Indemnifying Party, at the Indemnifying Party's expense, all witnesses,
pertinent records, materials and information in the Indemnified Party's
possession or under the Indemnified Party's control relating thereto as is
reasonably required by the Indemnifying Party. Similarly, in the event the
Indemnified Party is, directly or indirectly, conducting the defense against any
such Third Party Claim, the Indemnifying Party shall cooperate with the
Indemnified Party in such defense and make available to the Indemnified Party,
at the Indemnifying Party's expense, all such witnesses, records, materials and
information in the Indemnifying Party's possession or under the Indemnifying
Party's control relating thereto as is reasonably required by the Indemnified
Party. No such Third Party Claim may be settled by the Indemnifying Party
without the prior written consent of the Indemnified Party, which consent shall
not be unreasonably withheld or delayed.

         SECTION 6.03. Limits on Indemnification. (a) Notwithstanding anything
to the contrary contained in this Agreement, the maximum amount of indemnifiable
Losses which may be recovered from the Company arising out of or resulting from
the causes enumerated in Section 6.02(a) shall be (x) prior to the Option
Closing, if any, $4,500,000 and (y) following the Option Closing, if any
$6,000,000. Notwithstanding any provision of this Agreement, for the avoidance
of doubt, the parties expressly acknowledge and agree that the indemnification
provisions set forth in the Distribution Agreement are not affected in any way
by this Agreement, including, without limitation, by any provision of this
Article VI, and remain in full force and effect in accordance with the terms of
the Distribution Agreement.

         (b) Notwithstanding anything herein to the contrary, in no event shall
the Company or the Purchaser indemnify hereunder the other from and against any
facts or circumstances relating to their respective performance of any of their
respective obligations under the Distribution Agreement or otherwise in respect
of matters, directly or indirectly, relating to the Distribution Agreement.

         (c) Notwithstanding anything to the contrary elsewhere in this
Agreement, Losses shall not include, and no Indemnifying Party shall, in any
event, be liable to any other party for, any consequential, punitive or special
damages (including, but not limited to, damages for lost profits).


                                   ARTICLE VII

Agreement. The failure of any party to assert any of its rights hereunder shall
not constitute a waiver of any of such rights.

Agreement, all costs and expenses, including, without limitation, fees and
disbursements of counsel, financial advisors and accountants, incurred in

    arbitrator is appointed and shall continue from day to day until completed.

         (iii) The arbitrator shall issue his or her award in writing no later
    than 20 calendar days after the conclusion of the hearing. The arbitration
    award shall be final and binding regardless of whether any party fails or
    refuses to participate in the arbitration. The arbitrator is empowered to
    hear and determine all disputes between the parties hereto concerning the
    subject matter of this Agreement, and the arbitrator may award money damages
    (but specifically not punitive damages), injunctive relief, rescission,
    restitution, costs, and attorneys' fees. The arbitrator shall not have the

                                   ARTICLE II

                                   GOVERNANCE

              SECTION 2.01. Board Representation. From and after the date
hereof,

              (a) for as long as the Stockholder and any Permitted Transferees,
in the aggregate, Beneficially Own any combination of Company securities
consisting of, or convertible into, in the aggregate, at least 20% of the issued
and outstanding shares of Common Stock, the parties hereto shall use best
efforts and exercise all authority under applicable law to (i) cause the Board
to consist of seven Directors and (ii) cause any slate of Directors presented to
the stockholders of the Company for election to the Board to consist of such
nominees that, if elected, would result in a Board that included two Stockholder
Directors as designated by the Stockholder (which designees shall be subject to
the reasonable satisfaction of the Company).

              (b) for as long as the Stockholder and any Permitted Transferees,
in the aggregate, Beneficially Own any combination of Company securities
consisting of, or convertible into, in the aggregate, at least 15% but less than
20% of the issued and outstanding shares of Common Stock, the parties hereto
shall use best efforts and exercise all authority under applicable law to cause
any slate of Directors presented to the 

837578.1
                                        3

<PAGE>

stockholders of the Company for election to the Board to consist of such nominee
that, if elected, would result in a Board that included one Stockholder Director
as designated by the Stockholder (which designee shall be subject to the
reasonable satisfaction of the Company).


              (c) If the Stockholder and any Permitted Transferees, in the
aggregate, Beneficially Own any combination of Company securities consisting of,
or convertible into, in the aggregate, less than 15% of the issued and
outstanding shares of Common Stock, the Company shall have no obligation
pursuant to this Agreement to cause any slate of Directors presented to the
stockholders of the Company for election to the Board to include any designee of
the Stockholder.

              SECTION 2.02. Resignations and Replacements. (a) If a Stockholder
Director ceases to serve as a Director for any reason (a "Departing Stockholder
Director"), the Company shall take all action necessary to ensure that the
vacancy created by such Departing Stockholder Director shall be filled by an
individual designated by the Stockholder (which designee shall be to the
reasonable satisfaction of the Company), which individual shall serve out the
remaining term of the Departing Stockholder Director as a Stockholder Director.

              (b) In the event that at any time the Stockholder shall no longer
be entitled to designate Directors pursuant to Section 2.01, then the
Stockholder Directors shall be deemed to have resigned immediately upon the
occurrence of such event and the Company and the Stockholder shall take all
action promptly to effect the resignation or removal of such Directors.

              SECTION 2.03. Committees. For so long as there are two Stockholder
Directors, the Company will take all actions necessary to cause the appointment
of at least one Stockholder Director to serve on each committee of the Board. If
there is only one Stockholder Director, the Company will not be obligated to
take any such actions; provided that, if the Company forms an executive
committee or a committee by any such other name that performs functions similar
to those typically performed by an executive committee, the Company will take
all actions necessary to cause the appointment of such Stockholder Director to
serve on such committee.


                                   ARTICLE III

                               VOTING OBLIGATIONS

              SECTION 3.01. Voting Obligations. The Stockholder and any
Permitted Transferees agree to vote, and shall vote, at all times all of the
Shares Beneficially Owned by them for the election of the entire slate of Board
nominees established by the Board and submitted to the stockholders of the
Company for approval if, and to the extent that, all of the Stockholder's

837578.1
                                        4

<PAGE>


designated Stockholder Directors are included with such nominees; provided that
if the Company is in breach of any of its material obligations under the
Alliance Agreements as finally determined pursuant to the arbitration procedures
set forth in the relevant Alliance Agreement, the Stockholder and any Permitted
Transferees may refrain from voting any shares of Common Stock Beneficially
Owned by them in favor of, but may not vote against, the election of the entire
slate of Board nominees established by the Board; provided further that if such
abstention would have the same effect as a vote against the matter or would act
to make it impossible to obtain a quorum, the Stockholder and any Permitted
Transferees shall vote (and shall be deemed to have voted) all shares of Common
Stock Beneficially Owned by them in the same proportion of the votes cast by the
other stockholders of the Company of the applicable class of Company securities.


                                   ARTICLE IV

                       STANDSTILL AND TRANSFER PROVISIONS

              SECTION 4.01. Standstill Period. The "Standstill Period" shall
mean any period beginning on or after the date hereof during which the
Stockholder and any Permitted Transferees, in the aggregate, Beneficially Own
any combination of Company securities consisting of, or convertible into, in the
aggregate, 5% or more of the issued and outstanding shares of Common Stock. The
Stockholder represents and warrants to the Company that the Stockholder,
together with its "Affiliates" and "associates" (as such term is defined under
Rule 12b-2 of the Exchange Act, or any successor thereto), Beneficially Own an
aggregate, as of the date hereof, of 4,500,000 shares of Common Stock, and no
other securities of the Company whatsoever other than the Option.

              SECTION 4.02. Transfer Restrictions. (a) For as long as both (i)
the Standstill Period is in effect and (ii) the Distribution Agreement shall not
have expired and shall not have been terminated in its entirety or with respect
to the United States of America portion of the Territory (as defined in the
Distribution Agreement), the Stockholder shall not, and shall cause any
Permitted Transferees not to, directly or indirectly, sell, transfer, assign,
pledge, hypothecate or otherwise dispose of ("Transfer") any shares of Common
Stock except to any wholly owned subsidiary of the Stockholder that expressly
assumes the Stockholder's obligations under this Agreement relating to such
shares of Common Stock (a "Permitted Transferee").

              (b) During any period when either of the conditions described in
clause 4.02(a)(i) or (ii) are absent, the Stockholder or its Permitted
Transferees shall be permitted to Transfer shares of Common Stock only in
accordance with the provisions of Section 4.04.

              (c) The Stockholder agrees that it will not, directly or
indirectly, Transfer its interests in any Permitted Transferee unless prior
thereto the shares of Common Stock held by such entity are transferred to the
Stockholder or to one or more other Permitted Transferees.

              (d) Any attempted Transfer in violation of this Section 4.02 shall
be null, void and of no force and effect.

              SECTION 4.03. Acquisition of Additional Shares; Other
Restrictions. Subject to the provisions of Sections 4.05 and 4.06 and subject to
the Stockholder's right to exercise the Option under the Stock Subscription
Agreement, during a Standstill Period, except with the prior approval of the
Board, the Stockholder shall not, directly or indirectly, and shall cause its
Permitted Transferees not to, directly or indirectly:

     (a) acquire, offer to acquire, or agree to acquire beneficial ownership of
any additional equity or debt securities of the Company;

     (b) make, or in any way participate in, directly or indirectly, any
"solicitation" of "proxies" or become a "participant" in any "election contest"
with respect to the Company, or execute any written consent in lieu of a meeting
of stockholders of the Company;

     (c) initiate, propose or otherwise solicit stockholders for the approval of
one or more stockholder proposals with respect to the Company or induce or
attempt to induce any other Person to initiate any stockholder proposal;

     (d) seek nomination or election to the Board, serve on the Board if
elected, seek to place a representative on the Board or seek the removal of any
member of the Board (except with respect to the Stockholder's rights to
designate Stockholder Directors);

     (e) subject to the Stockholder's rights to consult with the Stockholder
Directors, call or seek to have called any meeting of the stockholders of the
Company;

     (f) otherwise act, directly or indirectly, alone or in concert with others,
to (i) subject to the Stockholder's rights to consult with the Stockholder
Directors, seek to control the management of the Company or the Board or the
policies or affairs of the Company, (ii) subject to the Stockholder's rights to
consult with the Stockholder Directors, solicit, propose, seek to effect or
negotiate with any other Person with respect to any form of business combination

recapitalization or similar transaction with respect to the Company or any
Subsidiary thereof, (iii) solicit, make or propose or encourage, or negotiate
with any other Person with respect to, or announce an intention to make, any


837578.1
                                        6

<PAGE>


tender offer or exchange offer for any debt or equity securities of the Company,
(iv) disclose an intention, purpose, plan or proposal with respect to the
Company or any debt or equity securities of the Company, or (v) subject to the
Stockholder's rights to consult with the Stockholder Directors, assist,
participate in, facilitate, encourage or solicit any effort or attempt by any
Person to do or seek to do any of the foregoing; provided, however, that nothing
in this Section 4.03(f) shall apply to discussions between or among officers,
employees or agents of the Stockholder, the Permitted Transferees and the
Stockholder Directors;

     (g) request the Company (or its Directors, officers, employees or agents),
directly or indirectly, to amend or waive any material provisions set forth
herein; or

     (h) encourage or render advice to or make any recommendation or proposal to
any Person to engage in any of the actions covered hereby.

     Nothing contained in this Section 4.03 shall be deemed or construed to
limit any Stockholder Director from casting any vote in his or her capacity as a
member of the Board (or otherwise acting at the direction of the Board, in such
capacity) or the exercise by the Stockholder or any Permitted Transferee of its
voting rights with respect to any shares of Common Stock it Beneficially Owns.

     SECTION 4.04. Company Rights of First Negotiation; Permitted Sales.
a) During any period that the condition described in clause (ii) of Section
4.02(a) shall no longer exist but there shall be a Standstill Period, if the
Stockholder or any Permitted Transferee shall desire to Transfer any shares of
Common Stock owned by it other than to a Permitted Transferee, then the Company
and the Stockholder shall negotiate in good faith in order to reach a mutually
agreeable disposition of all shares of Common Stock owned by the Stockholder and
any Permitted Transferees to one or more third parties or for the repurchase by
the Company of all of such shares of Common Stock; provided that neither the
Company nor the Stockholder (nor any Permitted Transferee) shall be obligated to
effect any such disposition or repurchase, and neither party shall be obligated
to so negotiate for a period in excess of six months. If after such six-month
period the parties are unable to reach a definitive agreement with respect to a
mutually agreeable disposition or repurchase of the Shares, then the Stockholder
and any such Permitted Transferee may sell its shares of Common Stock as
follows:

                (i)   in unsolicited broker transactions as contemplated by Rule
      144 under the Securities Act;

                (ii) in one or more private transactions to any third party
      ("Proposed  Transferee"),   but  only  if  such  Proposed  Transferee
      executes  and  delivers  to the Company  the  standstill,  voting and
      transfer limitation agreement in the form of Annex A hereto; and


837578.1
                                        7

<PAGE>


                (iii) in a widely disbursed underwritten public offering of
      such  shares of Common  Stock  pursuant  to which no Person or entity
      acquires  more than 5% of the number of shares of Common Stock issued
      and outstanding at the time of such offering.

To the extent the Stockholder and any Permitted Transferees are permitted to
Transfer any shares of Common Stock pursuant to this Section 4.04(a), the
Company shall cause to be issued to the Stockholder and such Permitted
Transferees, at their written request, new stock certificates representing such
shares without a restrictive legend regarding this Agreement (and the old stock
certificates shall be surrendered in order to receive the new stock
certificates). Notwithstanding anything herein to the contrary, no shares of
Common Stock may be sold, transferred, assigned or otherwise disposed of unless
registered by the Company pursuant to the Securities Act and any applicable
state laws, or unless an exemption therefrom is available.

     (b) During any period in which the conditions described in both clauses (i)
and (ii) of Section 4.02(a) shall no longer exist, the Stockholder and any
Permitted Transferees shall be permitted to freely Transfer any and all shares
of Common Stock without restriction and the Company shall cause to be issued to
the Stockholder and any Permitted Transferees, at their written request, new
stock certificates representing shares of Common Stock without a restrictive
legend regarding this Agreement (and the old stock certificates shall be
surrendered in order to receive the new stock certificates). Notwithstanding
anything herein to the contrary, no shares of Common Stock may be sold,
transferred, assigned or otherwise disposed of unless registered by the Company
pursuant to the Securities Act and any applicable state laws, or unless an
exemption therefrom is available.

              SECTION 4.05. Stockholder Rights of First Notice. Following the
Option Closing, if any, in the event the Company determines to issue and sell to
a third party any Company securities (other than Company securities issued and
sold by the Company in a widely disbursed public offering, Company securities
issued pursuant to a registration statement on Securities Act Form S-4 or S-8,
or its successors, or options issued pursuant to the Company Benefit Plans or
similar plans), the Company shall deliver to the Stockholder not less than 30
days' prior written notice of its intention to do so. Following the delivery of
such notice to the Stockholder, the Company shall negotiate with the Stockholder
for such thirty-day period for the purpose of permitting the Stockholder to
make, in its sole discretion, one or more proposals to the Company regarding the
Stockholder's desire to acquire the Company securities. Following the expiration
of such thirty-day period, the Company may effect the issuance and sale of the
Company securities to any such third party, without limitation or further
obligation to the Stockholder. Notwithstanding anything herein to the contrary,
in no event shall the Company be obligated, for any reason, to issue and sell to
the Stockholder any Company securities.

              SECTION 4.06. Anti-Dilutive Rights. (a) Except as provided in
Section 4.06(c) below, the Company shall not issue, sell or Transfer, whether in
private issuances or sales or in a registered public offering, any Common Stock
or securities convertible into Common Stock to 

837578.1
                                       8

<PAGE>


any Person unless the Stockholder and any Permitted Transferees are offered in
writing the right to purchase, at the same price and on the same terms proposed
to be issued and sold, an amount of such Common Stock or other securities (the
"Maintenance Shares") as is necessary for the Stockholder and any Permitted
Transferees to maintain, individually, the level of their respective percentage
Beneficial Ownership of Common Stock (on a Fully Diluted Basis) as it owned
immediately prior to such issuance ("Anti-Dilutive Rights"). In the case of a
public offering, the Company shall, as part of its offer, provide a copy of any
preliminary prospectus and other information concerning the offering reasonably
requested by the Stockholder or any Permitted Transferees. The Stockholder and
any Permitted Transferee shall have the right, during the period specified in
Section 4.06(b), to accept the offer for any or all of the Maintenance Shares
offered to each of them.

     (b) If the Stockholder or any Permitted Transferee does not deliver to the
Company written notice of acceptance of any offer made pursuant to Section
4.06(a) within 10 Business Days after the Stockholder's or any such Permitted
Transferee's receipt of such offer, the Stockholder or such Permitted
Transferee, as the case may be, shall be deemed to have waived its right to
purchase all or any part of its Maintenance Shares as set forth in such offer,
but the Stockholder or any such Permitted Transferee shall retain its rights
under this Section 4.06 with respect to future offers; provided, however, that
the applicable number of Maintenance Shares shall be reduced and recalculated
immediately prior to any such future issuance.

     (c) The Anti-Dilutive Rights set forth in this Section 4.06 shall not apply
to the grant or exercise of options to purchase Common Stock to employees or
Directors of the Company or any of its Subsidiaries or otherwise pursuant to a
Company Benefit Plan or similar plan in existence on the date hereof or
otherwise adopted by the Board hereafter (whether or not such options were
issued prior to the date hereof, or are hereafter issued), (ii) the issuance of
shares of Common Stock issuable upon exercise of any option, warrant,
convertible security or other rights to purchase or subscribe for Common Stock
which, in each case, had been issued by the Company prior to the date of this
Agreement or (iii) securities issued pursuant to any stock split, stock dividend
or other similar stock recapitalization.

     (d) A closing for the purchase of shares of Common Stock pursuant to this
Section 4.06 shall occur on the later of (i) the date on which such public or
private issuance occurs and (ii) such date as may be mutually agreed to by the
Company and the Stockholder or the Permitted Transferee, as the case may be, and
shall take place at the offices of the Company or at such other reasonable
location as the Company may otherwise notify the Stockholder and/or a Permitted
Transferee, as the case may be, at the time specified by the Company in such
notice provided to the Stockholder or the Permitted Transferee, as the case may
be, at least five days prior to such closing date. In connection with such
closing, the Company and the Stockholder or Permitted Transferee, as the case
may be, shall provide such closing certificates and other closing deliveries
provided in the transaction giving rise to the rights specified in Section 4.06.

     (e) Solely to the extent that the Stockholder suffers dilution as a result
of the exercise of employee stock options, then, notwithstanding the provisions
of Section 4.03, the Stockholder at any time thereafter may purchase shares of
Common Stock from a third party or through one or more open market purchases for
the purposes of maintaining its percentage level of Beneficial Ownership of
Common Stock. The Company and the Stockholder shall use all commercially
reasonable efforts to cooperate with each other so as to permit the
Stockholder to exercise its rights under this Section 4.06(e) in an accurate,
orderly and nondisruptive manner (provided that in no event shall any purchase
be affected more than once in any fiscal quarter).

                                    ARTICLE V

                               REGISTRATION RIGHTS

              SECTION 5.01. Restrictive Legend. Each certificate representing
shares of Common Stock held by Stockholder shall, except as otherwise provided
in this Article V, be stamped or otherwise imprinted with a legend substantially
in the following form:

      THIS SECURITY HAS NOT BEEN  REGISTERED  UNDER THE  SECURITIES  ACT OF
      1933, AS AMENDED (THE "ACT"), AND MAY NOT BE TRANSFERRED OR OTHERWISE
      DISPOSED  OF  UNLESS  IT HAS  BEEN  REGISTERED  UNDER  THE  ACT OR AN
      EXEMPTION FROM REGISTRATION IS AVAILABLE.

      THE SECURITY  REPRESENTED  BY THIS  CERTIFICATE IS SUBJECT TO CERTAIN
      RESTRICTIONS ON TRANSFER AND CERTAIN RESTRICTIONS ON VOTING CONTAINED
      IN  THE  STOCKHOLDER'S  AGREEMENT,  DATED  AS OF MAY 3 ,1999,  BY AND
      BETWEEN THE COMPANY AND COBE LABORATORIES, INC.

A certificate  shall not bear the Securities Act legend or the legend  regarding
this Agreement, as the case may be, if in the opinion of counsel satisfactory to
the Company (it being agreed that  Shearman & Sterling  shall be  satisfactory),
the shares being sold thereby may be publicly  sold without  registration  under
the Securities Act or may be sold without being subject to the  restrictions  on
sale specified in Article IV.

              SECTION 5.02. Notice of Proposed Transfer. Prior to any proposed
Transfer of any shares of Registrable Stock (other than under the circumstances
described in Section 5.03, 5.04 or 5.05), the Stockholder shall give written
notice to the Company of its intention to effect such Transfer. Each such notice
shall describe the manner of the proposed Transfer whereupon the Stockholder
shall be entitled to Transfer such stock in accordance with the terms of its
notice, except as may be precluded hereunder and subject in any event to the
restrictions set forth in this 

837578.1
                                       10

<PAGE>


Agreement. Each certificate representing shares of Common Stock transferred as
above provided shall bear the legends set forth in Section 5.01, except that
such certificate (a) shall not bear the Securities Act legend if (i) such
Transfer is in accordance with the provisions of Rule 144 of the Securities Act
(or any other rule permitting public sale without registration under the
Securities Act, but not Rule 144A of the Securities Act) or (ii) the opinion of
counsel referred to above is to the further effect that the transferee and any
subsequent transferee (other than an Affiliate of the Company) would be entitled
to Transfer such securities in a public sale without registration under the
Securities Act and (b) shall not bear the legend related to this Agreement if
such Transfer is to a third party in accordance with the provisions of Article
IV and such transferee is not subject to the restrictions on Transfer set forth
in this Agreement. The restrictions provided for in this Section 5.02 shall not
apply to securities that are not required to bear the legends prescribed by
Section 5.01 in accordance with the provisions of Section 5.01.

              SECTION 5.03. Required Registrations. (a) Commencing at any time
after September 15, 1999, for as long as the Stockholder holds five percent or
more of the outstanding shares of Common Stock of the Company, the Stockholder
may request in a written notice (which request shall state the number of
Registrable Shares to be so registered, the intended method of distribution and
a certification as to the market value of such shares, as described below), that
the Company file a registration statement under the Securities Act (or a similar
document pursuant to any other statute then in effect corresponding to the
Securities Act) covering the registration of any or all Registrable Stock owned
by the Stockholder and any Permitted Transferee, provided that either (i) such
Registrable Stock has an aggregate offering price of at least $3,000,000 (based
on the last reported sale price for the Common Stock on the Business Day
preceding the date of such written request, as reported by the OTC Bulletin
Board or any other exchange or market on which the Common Stock is then listed
or included for quotation) or (ii) such Registrable Stock represents 100% of any
combination of Company securities consisting of, or convertible into, shares of
Common Stock Beneficially Owned by the Stockholder and its Permitted
Transferees. Following receipt of any notice under this Section 5.03, the
Company shall use its best efforts to cause to be registered under the
Securities Act all Registrable Stock that the Stockholder requested be
registered in accordance with the manner of disposition specified in such
notice.

     (b) If the Stockholder intends to have the Registrable Stock distributed by
means of an underwritten offering, the Stockholder and the Company shall enter
into an underwriting agreement in customary form with the underwriter or
underwriters which shall contain any customary provisions (including customary
provisions with respect to indemnification by the Company of the underwriters)
as the underwriters may reasonably request. Such underwriter or underwriters
shall be selected by the Stockholder and shall be approved by the Company, which
approval shall not be unreasonably withheld.

     (c) Notwithstanding any provision of this Agreement to the contrary:

               (i) The Company shall not be required to effect a registration
     pursuant to this Section 5.03 during this period starting with the date
     which is 30 days prior to the date of the initial public filing by the
     Company of, and ending on a date 120 days following the effective date of,
     a registration statement pertaining to a public offering of securities for
     the account of the Company or on behalf of the selling stockholders under
     any other registration rights agreement which the Stockholder has been
     entitled to join pursuant to Section 5.04; provided that the Company shall
     actively employ in good faith all reasonable efforts to cause such
     registration statement to become effective as soon as possible;

               (ii) if (A) (i) the Company is in possession of material
     nonpublic information relating to the Company or any Subsidiary and (ii)
     the Company determines in good faith that public disclosure of such
     material nonpublic information would not be in the best interests of the
     Company and its stockholders, (B) (i) the Company has made a public
     announcement relating to an acquisition or business combination transaction
     that includes the Company and/or one or more of its Subsidiaries that is
     material to the Company and its Subsidiaries, taken as a whole and (ii) the
     Company determines in good faith that (x) offers and sales of Registrable
     Stock pursuant to any registration statement prior to the consummation of
     such transaction (or such earlier date as the Company shall determine) is
     not in the best interests of the Company and its stockholders or (y) it
     would be impracticable at the time to obtain any financial statements
     relating to such acquisition or business combination transaction that would
     be required to be set forth in a registration statement or (C) the Company
     shall furnish to the Stockholder a certificate signed by the president of
     the Company stating that in the good faith opinion of the Board such
     registration would interfere with any material transaction or financing,
     confidential negotiations or business activities then being pursued by the
     Company or any of its Subsidiaries, then, in any such case, the Company's
     obligation to use all reasonable efforts to file a registration statement
     shall be deferred, or the effectiveness of any registration statement may
     be suspended, in each case for a period not to exceed 120 days; provided
     that the Company may not delay the filing or suspend the effectiveness of
     any registration statement under this Section 5.03(ii) on more than one
     occasion in any consecutive 12-month period;

               (iii) the Company shall not be required to effect a registration
     pursuant to this Section 5.03 if the Registrable Stock requested by the
     Stockholder to be registered pursuant to such registration is included in,
     and eligible for sale under, a Shelf Registration (as defined below); and

               (iv) the Company shall not be required to effect a registration
     pursuant to this Section 5.03 within six months after the effective date of
     any other registration statement registering shares to be sold by the
     Company.

     (d) The Company shall not be obligated to effect and pay for more than two
registrations pursuant to this Section 5.03 (both of which may be Shelf
Registrations requested pursuant to Section 5.05); provided that a registration
requested pursuant to this Section 5.03 shall not be deemed to have been
effected for purposes of this Section 5.03(d) unless (i) it has been declared
effective by the SEC, (ii) it has remained effective for the period set forth in
Section  5.06(a) and (iii) the offering of  Registrable  Stock  pursuant to such
registration  is not  subject to any stop  order,  injunction  or other order or
requirement  of the SEC (other  than any such stop order, injunction, or other 
requirement of the SEC prompted by any act or omission of the Stockholder).

              SECTION 5.04. Incidental Registration. (a) Subject to Section
5.09, if at any time the Company determines that it shall file a registration
statement under the Exchange Act for the registration of Common Stock (other
than a registration statement on a Form S-4 or S-8 or an offering of securities
solely to the Company's existing stockholders) on any form that would also
permit the registration of the Registrable Stock and such filing is to be on its
behalf or on behalf of selling holders of its securities for the general
registration of Common Stock to be sold for cash, the Company shall each such
time promptly give the Stockholder written notice of such determination setting
forth the date on which the Company proposes to file such registration
statement, which date shall be no earlier than 15 days from the date of such
notice, and advising the Stockholder of its right to have Registrable Stock
included in such registration. Upon the written request of the Stockholder
received by the Company no later than 10 days after the date of the Company's
notice (which request shall state the number of Registrable Shares to be so
registered and the intended method of distribution), the Company shall, subject
to Section 5.04(b) below, use all reasonable efforts to cause to be registered
under the Securities Act all of the Registrable Stock that the Stockholder has
so requested to be registered; provided that the Company shall have the right to
postpone or withdraw any registration effected pursuant to this Section 5.04
without obligation or liability to the Stockholder.

     (b) If, in the opinion of the managing underwriter (or, in the case of a
non-underwritten offering, in the good faith reasonable opinion of the
Company), the total amount of such securities to be so registered, including
such Registrable Stock, will exceed the maximum amount of the Company's
securities which can be marketed (i) at a price reasonably related to the then
current market value of such securities or (ii) without otherwise materially and
adversely affecting the entire offering, then the Company shall be entitled to
reduce the number of shares of Registrable Stock to be sold in such offering by
the Stockholder and any other stockholder of the Company requesting to be
included in the registration in proportion (as nearly as practicable) to the
amount of shares of Common Stock requested to be included by the Stockholder and
each other stockholder at the time of filing the registration statement.

              SECTION 5.05. Shelf Registration. (a) The Stockholder may use its
two request registration rights granted pursuant to Section 5.03, subject to the
limitations of Section 5.03(d), to request that the Company file a "shelf'
registration statement pursuant to Rule 415 under the 

837578.1
                                       13

<PAGE>


Securities Act or any successor rule (the "Shelf Registration" with respect to
the Registrable Stock. The Company shall (i) use all reasonable efforts to have
the Shelf Registration filed within 30 days of such request and declared
effective as soon as reasonably practicable following such request and (ii)
subject to Section 5.03(c)(iii), use all reasonable efforts to keep the Shelf
Registration continuously effective from the date such Shelf Registration is
declared effective until at least the earlier of such time as (A) all such
Registrable Stock has been sold thereunder or (B) the first anniversary of such
effective date in order to permit the prospectus forming a part thereof to be
usable by the Stockholder during such period.

     (b) Subject to Section 5.03(c)(iii), the Company shall supplement or amend
the Shelf Registration (i) as required by the registration form utilized by the
Company or by the instructions applicable to such registration form or by the
Securities Act, (ii) to include in such Shelf Registration any additional
securities that become Registrable Stock by operation of the definition thereof
and (iii) following the written request of the Stockholder pursuant to Section
5.05(c), to cover offers and sales of all or a part of the Registrable Stock by
means of an underwriting. The Company shall furnish to the Stockholder copies of
any such supplement or amendment sufficiently in advance (but in no event less
than five Business Days in advance) of its use or filing with the SEC to allow
the Stockholder a meaningful opportunity to comment thereon.

     (c) The Stockholder may, at its election and upon written notice by the
Stockholder to the Company, subject to the limitations set forth in Section
5.03(c)(iii), effect offers and sales under the Shelf Registration by means of
one or more underwritten offerings, in which case the provisions of Section
5.03(b) shall apply to any such underwritten distribution of securities under
the Shelf Registration and such underwriting shall, if sales of Registrable
Stock pursuant thereto shall have closed, be regarded as the exercise of one of
the registration rights contemplated by Section 5.03.

              SECTION 5.06. Obligations of the Company. Whenever required under
Sections 5.03 and 5.05 to effect the registration of any Registrable Stock under
the Securities Act, the Company shall:

     (a) in a reasonably timely manner, file with the SEC a registration
statement with respect to such Registrable Stock, and use best efforts to cause
such registration statement to become and remain effective for the period of the
distribution contemplated thereby determined as provided hereafter; provided
that the Company shall not be required to keep any Registration Statement (other
than the Shelf Registration) effective more than 90 days;

     (b) as expeditiously as possible, prepare and file with the SEC such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to comply with the provisions
of the Securities 

837578.1
                                       14

<PAGE>


Act with respect to the disposition of all Registrable Stock
covered by such registration statement;

     (c) as expeditiously as possible, furnish to the Stockholder such
reasonable numbers of copies of the registration statement and the prospectus
included therein (including each preliminary prospectus and any amendments or
supplements thereto) in conformity with the requirements of the Securities Act,
any exhibits filed therewith and such other documents and information as they
may reasonably request;

     (d) as expeditiously as possible, use best efforts to register or qualify
the Registrable Stock covered by such registration statement under such other
securities or "blue sky" laws of such states as shall be reasonably requested by
the Stockholder for the distribution of the Registrable Stock covered by the
registration statement; provided, however, that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business in or to file a general consent to service of process in any
jurisdiction wherein it would not but for the requirements of this paragraph
(except that the Company will use its best efforts to register or qualify
Registrable Stock in such additional jurisdiction as the Stockholder may request
subject to the foregoing proviso and at the Stockholder's own expense) be
obligated to do so; and provided further that the Company shall not for any
purpose be required to qualify such Registrable Stock in any jurisdiction in
which the securities regulatory authority requires that the Stockholder submit
any shares of Registrable Stock to the terms, provisions and restrictions of any
escrow, lockup or similar agreement(s) for consent to sell Registrable Stock in
such jurisdiction unless the Stockholder agrees to do so;

     (e) promptly notify the Stockholder, at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of the happening
of any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances under
which they were made, and at the request of the Stockholder promptly prepare and
furnish to the Stockholder a reasonable number of copies of a supplement to or
an amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances under which they were made. In the
event the Company shall give such notice, the Company shall extend the period
during which such Registration Statement shall be maintained effective as
provided in Section 5.06(a) (or, in the case of the Shelf Registration, Section
5.05(a)) by the number of days during the period from and including the date of
the giving of such notice to the date when the Company shall make available to
the Stockholder such supplemented or amended prospectus;

      (f) furnish, at the request of the Stockholder, if the method of
distribution is by means of an underwriting, on the date that the shares of
Registrable Stock are delivered to the underwriters for sale pursuant to such
registration or, if such Registrable Stock is not being sold through
underwriters, on the date that the registration statement with respect to such
shares of Registrable Stock becomes effective, (1) a signed opinion, dated on or
about such date, of the independent legal counsel representing the Company for
the purpose of such registration, addressed to the underwriters, if any, and if
such Registrable Stock is not being sold through underwriters, then to the
Stockholder, as to such matters as such underwriters or the Stockholder, as the
case may be, may reasonably request and as would be customary in such a
transaction, and (2) letters dated on or about such date and the date the
offering is priced from the independent certified public accountants of the
Company, addressed to the underwriters, if any, and if such Registrable Stock is
not being sold through underwriters, then to the Stockholder, if such
accountants refuse to deliver such letters to the Stockholder, then to the
Company (i) stating that they are independent certified public accountants
within the meaning of the Securities Act and that, in the opinion of such
accountants, the financial statements and other financial data of the Company
included in the registration statement or the prospectus, or any amendment or
supplement thereto, comply as to form in all material respects with the
applicable accounting requirements of the Securities Act and (ii) covering such
other financial matters (including information as to the period ending not more
than five Business Days prior to the date of such letters) with respect to the
registration in respect of which such letter is being given as such underwriters
or the Stockholder, as the case may be, may reasonably request and as would be
customary in such a transaction;

     (g) enter into customary agreements (including, if the method of
distribution is by means of an underwriting, an underwriting agreement in
customary form) and take such other actions as are reasonably required in order
to expedite or facilitate the disposition of the Registrable Stock to be so
included in the registration statement;

     (h) otherwise use best efforts to comply with all applicable rules and
regulations of the SEC, and make available to its securityholders, as soon as
reasonably practicable, but not later than 18 months after the effective date of
the registration statement, an earnings statement covering the period of at
least 12 months beginning with the first full month after the effective date of
such registration statement, which earnings statements shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; and

     (i) use all reasonable efforts to list the Registrable Stock covered by
such registration statement with any U.S. nationally recognized securities
exchange on which the Company Common Stock is then listed.

For purposes of Sections  5.06(a) and  5.06(b),  the period of  distribution  of
Registrable  Stock in a firm  commitment  underwritten  public offering shall be
deemed to extend until each  underwriter  has completed the  distribution of all
securities  purchased by it, and the period of distribution of Registrable Stock
in any other  registration  shall be deemed to extend  until the  earlier of the
sale of all Registrable Stock covered thereby and six months after the effective
date thereof.

              SECTION 5.07. Furnish Information. It shall be a condition
precedent to the obligations of the Company to take any action pursuant to
Article V of this Agreement that the Stockholder shall furnish to the Company
such information regarding the Stockholder, the Registrable Stock held by it,
and the intended method of disposition of such securities as the Company shall
reasonably request and as shall be required in connection with the action to be
taken by the Company.

              SECTION 5.08. Expenses of Registration. All expenses incurred in
connection with each registration pursuant to Sections 5.03, 5.04 and 5.05 of
this Agreement, excluding underwriters' discounts and commissions, but
including, without limitation, all registration, filing and qualification fees,
word processing, duplicating, printers' and accounting fees (including the
expenses of any special audits or "cold comfort" letters required by or incident
to such performance and compliance), fees of the National Association of
Securities Dealers, Inc. or listing fees, messenger and delivery expenses, all
fees and expenses of complying with state securities or "blue sky" laws, and the
fees and disbursements of counsel for the Company, and the reasonable fees and
disbursements of counsel for the Stockholder (which counsel shall be selected by
the Stockholder), shall be paid by the Company; provided, however, that if a
registration request pursuant to Section 5.03 or 5.05 is subsequently withdrawn
by the Stockholder, the Company shall not be required to pay any expenses of
such registration proceeding and the Stockholder shall bear such expenses. The
Stockholder shall bear and pay the underwriting commissions and discounts
applicable to securities offered for its account and the fees and disbursements
of its counsel in connection with any registrations, filings and qualifications
made pursuant to this Agreement.

              SECTION 5.09. Underwriting Requirements. In connection with any
underwritten offering, the Company shall not be required under Section 5.04 to
include shares of Registrable Stock in such underwritten offering unless the
Stockholder accepts the terms of the underwriting of such offering that have
been reasonably agreed upon between the Company and the underwriters selected by
the Stockholder.

              SECTION 5.10. Indemnification. In the event any Registrable Stock
is included in a registration statement under this Agreement:

     (a) The Company shall indemnify and hold harmless the Stockholder, the
Stockholder's directors and officers, each Person who participates in the
offering of such Registrable Stock, and each Person, if any, who controls the
Stockholder or participating

<PAGE>



Person within the meaning of the Securities Act, against any losses, claims,
damages or liabilities, joint or several, to which they may become subject under
the Securities Act, the Exchange Act, state securities or "blue sky" laws or
otherwise, insofar as such losses, claims, damages or liabilities (or
proceedings in respect thereof) arise out of or are based on any untrue or
alleged untrue statement of any material fact contained in such registration
statement on the effective date thereof (including any preliminary prospectus or
prospectus filed under Rule 424 under the Securities Act or any amendments or
supplements thereto) or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse the
Stockholder, the Stockholder's directors and officers, such participating Person
or controlling Person for any legal or other expenses reasonably incurred by
them (but not in excess of expenses incurred in respect of one counsel for all
of them unless there is an actual conflict of interest between any indemnified
parties, which indemnified parties may be represented by separate counsel) in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 5.10(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company; provided further that the Company shall not
be liable to the Stockholder, the Stockholder's directors and officers,
participating Person or controlling Person in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in connection with such registration statement,
preliminary prospectus, final prospectus or amendments or supplements thereto,
in reliance upon and in conformity with written information furnished expressly
for use in connection with such registration by the Stockholder, the
Stockholder's directors and officers, participating Person or controlling
Person. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Stockholder, the Stockholder's
directors and officers, participating Person or controlling Person, and shall
survive the Transfer of such securities by the Stockholder.

     (b) The Stockholder shall indemnify and hold harmless the Company, each of
its directors and officers, each Person, if any, who controls the Company within
the meaning of the Securities Act, and each agent and any underwriter for the
Company (within the meaning of the Securities Act) against any losses, claims,
damages or liabilities, joint or several, to which the Company or any such
director, officer, controlling Person, agent or underwriter may become subject,
under the Securities Act, the Exchange Act, state securities or "blue sky" laws
or otherwise, insofar as such losses, claims, damages or liabilities (or
proceedings in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in such
registration statement on the effective date thereof (including any preliminary
prospectus or prospectus filed under Rule 424 under the Securities Act or any
amendments or 

837578.1
                                       18

<PAGE>


supplements thereto) or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in such registration
statement, preliminary or final prospectus, or amendments or supplements
thereto, in reliance upon and in conformity with written information furnished
by or on behalf of the Stockholder expressly for use in connection with such
registration; and the Stockholder shall reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
Person, agent or underwriter (but not in excess of expenses incurred in respect
of one counsel for all of them unless there is an actual conflict of interest
between any indemnified parties which indemnified parties may be represented by
separate counsel) in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this Section 5.10(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Stockholder, which consent
shall not be unreasonably withheld or delayed, and provided further that the
liability of the Stockholder hereunder shall be limited to the proportion of any
such loss, claim, damage,liability or expense which is equal to the proportion
that the net proceeds from the sale of the shares of Common Stock sold by the
Stockholder under such registration statement bears to the total net proceeds
from the sale of all securities sold thereunder, but not in any event to exceed
the net proceeds received by the Stockholder from the sale of Registrable Stock
covered by such registration statement.

     (c) Promptly after receipt by an indemnified party under this Section 5.10
of notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 5.10, notify the indemnifying party in writing of the commencement
thereof and the indemnifying party shall have the right to participate in and
assume the defense thereof with counsel selected by the indemnifying party and
reasonably satisfactory to the indemnified party; provided, however, that an
indemnified party shall have the right to retain its own counsel, with all fees
and expenses thereof to be paid by such indemnified party, and to be apprised of
all progress in any proceeding the defense of which has been assumed by the
indemnifying party. The failure to notify an indemnifying party promptly of the
commencement of any such action shall not relieve the indemnifying party from
any liability in respect of such action which it may have to such indemnified
party on account of the indemnity contained in this Section 5.10, unless (and
only to the extent) the indemnifying party was prejudiced by such failure, and
in no event shall such failure relieve the indemnifying party from any other
liability which it may have to such indemnified party. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any claim or pending or threatened proceeding in respect of which
the indemnified party is or could have been a party and indemnity could have
been 

837578.1
                                       19

<PAGE>


sought hereunder by such indemnified party, unless such settlement includes
an unconditional release of such indemnified party from all liability arising
out of such claim or proceeding.

     (d) To the extent any indemnification by an indemnifying party is
prohibited or limited by applicable law, the indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the indemnifying party and the indemnified party in connection with the
actions which resulted in such losses, claims, damages or liabilities as well as
any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of material fact or omission or alleged omission to
state a material fact, has been made by, or relates to information supplied by,
such indemnifying party or indemnified party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action. The amount paid or payable by a party as a result of the losses, claims,
damages or liabilities referred to above shall be deemed to include any legal or
other fees or expenses reasonably incurred by such party in connection with any
investigation or proceeding.


              The parties hereto agree that it would not be just and equitable
if contribution pursuant to this Section 5.10(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

              SECTION 5.11. Transfer of Registration Rights. Subject to Article
IV, the registration rights of the Stockholder under this Agreement with respect
to any Registrable Stock may be transferred to any Permitted Transferee of such
Registrable Stock; provided, however, that (i) the Stockholder shall give the
Company written notice at or prior to the time of such Transfer stating the name
and address of the Permitted Transferee and identifying the securities with
respect to which the rights under this Agreement are being transferred; (ii)
such Permitted Transferee shall agree in writing, in form and substance
reasonably satisfactory to the Company, to be bound by the provisions of this
Agreement as if it were a stockholder of the Company; and (iii) immediately
following such Transfer, the further disposition of such securities by such
transferee is restricted under the Securities Act.

              SECTION 5.12. Rule 144 Information. Subject to Article IV, and
with a view to making available the benefits of certain rules and regulations of
the SEC which may at any time 
837578.1
                                       20

<PAGE>


permit the sale of the Registrable Stock to the public without registration, at
all times after ninety (90) days after any Shelf Registration Statement covering
a public offering of securities of the Company under the Securities Act shall
have become effective, the Company agrees to:

     (a) make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

     (b) use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act; and

     (c) furnish to the Stockholder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of such Rule
144 and of the Securities Act and the Exchange Act, a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
so filed by the Company as the Stockholder may reasonably request in availing
itself of any rule or regulation of the SEC allowing the Stockholder to sell any
Registrable Stock without registration.

              SECTION 5.13. Limitations on Registration Rights. Notwithstanding
anything herein to the contrary, neither the Stockholder nor any Permitted
Transferee shall be entitled to exercise any registration rights specified in
this Article V for so long as the Stockholder is in material breach of any of
its covenants, agreements or other obligations under the Distribution Agreement.


                                   ARTICLE VI

                               GENERAL PROVISIONS

              SECTION 6.01. Waiver. The Company and the Stockholder may (a)
extend the time for the performance of any of the obligations or other acts of
the other party or (b) waive compliance with any of the agreements or conditions
of the other party contained herein. Any such extension or waiver shall be valid
only if set forth in an instrument in writing signed by the party to be bound
thereby. Any waiver of any term or condition shall not be construed as a waiver
of any subsequent breach or a subsequent waiver of the same term or condition,
or a waiver of any other term or condition, of this Agreement. The failure of
any party to assert any of its rights hereunder shall not constitute a waiver of
any of such rights.

              SECTION 6.02. Expenses. Except as otherwise specified in this
Agreement, all costs and expenses, including, without limitation, fees and
disbursements of counsel and financial advisors, incurred in connection with
this Agreement shall be paid by the party incurring such costs and expenses.

              SECTION 6.04. Headings. The descriptive headings contained in this
Agreement are for convenience of reference only and shall not affect in any way
the meaning or interpretation of this Agreement.

              SECTION 6.05. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any Law or
public policy, all other terms and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal

materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner in
order that the transactions contemplated hereby are consummated as originally
contemplated to the greatest extent possible.

              SECTION 6.06. Entire Agreement. This Agreement and the other
Alliance Agreements constitute the entire agreement of the parties hereto with
respect to the subject matter hereof and thereof and supersedes all prior
agreements and undertakings, both written and oral, between the Company and COBE
with respect to the subject matter hereof and thereof.

              SECTION 6.07. Assignment. This Agreement may not be assigned
without the express written consent of the Company and the Stockholder (which
consent shall not be unreasonably withheld or delayed by the Company or the

agreements contained in this Agreement by or on behalf of any parties hereto
will bind and inure to the benefit of their respective successors and assigns.

              SECTION 6.08. No Third Party Beneficiaries. Except for the
provisions of Section 5.10 relating to indemnified parties, this Agreement shall
be binding upon and inure solely to the benefit of the parties hereto and their
permitted assigns and nothing herein, express or implied, is intended to or
shall confer upon any other Person any legal or equitable right, benefit or
remedy of any nature whatsoever under or by reason of this Agreement.

              SECTION 6.09. Amendment. This Agreement may not be amended or
modified except (a) by an instrument in writing signed by, or on behalf of, the
Company and COBE or (b) by a waiver in accordance with Section 6.01.

              SECTION 6.10. Governing Law. This Agreement shall be governed by
the laws of the State of New York, excluding (to the greatest extent permissible
by law) any rule of law that would cause the application of the laws of any
jurisdiction other than the State of New York.

              SECTION 6.11. Arbitration. (a) If a dispute arises from or relates
to this Agreement or the breach thereof, whether of law or fact, of any nature
whatsoever, and such dispute cannot be settled through direct discussions
between the parties, the parties agree to endeavor first to settle the dispute
in an amicable manner by mediation administered by the American Arbitration
Association under its Commercial Mediation Rules before resorting to litigation.
Mediation shall take place in New York, New York. If the dispute cannot be
resolved within 60 days of the initiation thereof by such party, any party may
initiate arbitration in accordance with the provisions of Section 6.11(b) below.

              (b) All disputes arising under this Agreement that cannot be
amicably resolved under Section 6.11(a) above shall be settled by binding
arbitration. Judgment upon the award rendered may be entered in any court in the
New York, New York metropolitan area. Each party agrees to the following
arbitration procedures:

              (i) Any party requesting arbitration shall serve a written demand
         for arbitration on the other party. The demand shall set forth in
         reasonable detail a statement of the nature of the dispute, the amount
         involved and the remedies sought. No later than 20 calendar days after
         a demand for arbitration is served, the parties shall jointly select
         and appoint a retired judge of the Courts of the State of New York to
         act as the arbitrator. In the event that the parties do not agree on
         the selection of an arbitrator, the party seeking arbitration shall
         apply to the United States District Court for the Southern District of
         New York, as applicable, for appointment of a retired judge to serve as
         arbitrator.

              (ii) No later than 10 calendar days after appointment of an
         arbitrator, the parties shall jointly prepare and submit to the
         arbitrator a set of rules for the arbitration. In the event that the
         parties cannot agree on the rules for the arbitration, the arbitrator
         shall establish the rules. No later than 10 calendar days after the
         arbitrator is appointed, such arbitrator shall arrange for a hearing to
         commence on a mutually convenient date.


837578.1
                                       24

<PAGE>


         The hearing shall commence no later than 120 calendar days after the
         arbitrator is appointed and shall continue from day to day until
         completed.

              (iii) The arbitrator shall issue his or her award in writing no
         later than 20 calendar days after the conclusion of the hearing. The
         arbitration award shall be final and binding regardless of whether any
         party fails or refuses to participate in the arbitration. The
         arbitrator is empowered to hear and determine all disputes between the
         parties hereto concerning the subject matter of this Agreement, and the
         arbitrator may award money damages (but specifically not punitive
         damages), injunctive relief, rescission, restitution, costs, and
         attorneys' fees. The arbitrator shall not have the power to amend this
         Agreement in any respect.

              (iv) In the event that any party serves a proper demand for
         arbitration under this Agreement, all parties may pursue discovery in
         accordance with the Rules of Civil Procedure of the State of New York,
         the provisions of which are incorporated herein by reference, with the
         following exceptions: (A) the parties hereto may conduct all discovery,
         including depositions for discovery purposes, without leave of the
         arbitrator; and (B) all discovery shall be completed no later than the
         commencement of the arbitration hearing or 120 calendar days after the
         date that a proper demand for arbitration is served, whichever occurs
         earlier, unless upon a showing of good cause the arbitrator extends or
         shortens that period.

              SECTION 6.12. Counterparts. This Agreement may be executed in one
or more counterparts, and by the different parties hereto in separate
counterparts, each of which when executed shall be deemed to be an original but
all of which taken together shall constitute one and the same agreement.

              SECTION 6.13. Specific Performance. The parties hereto agree that
irreparable damage would occur in the event any provision of this Agreement was
not performed in accordance with the terms hereof and that the parties shall be
entitled to specific performance of the terms hereof, in addition to any other
remedy at law or equity.

              AMENDED AND RESTATED EXCLUSIVE DISTRIBUTION AGREEMENT
                                     BETWEEN
                                  HEMASURE INC.
                                       AND
                             COBE LABORATORIES, INC.


           Amended and Restated Exclusive Distribution Agreement (this
"Distribution Agreement") dated as of May 3, 1999, between HEMASURE INC., a
corporation organized under the laws of Delaware ("HemaSure"), and COBE
LABORATORIES, INC., a corporation organized under the laws of the State of
Colorado ("COBE").

                                    RECITALS

                     A. HemaSure manufactures and distributes certain medical
products and supplies, together with parts necessary for repair and replacement
and including all devices now or hereafter manufactured or designed by HemaSure
that filter blood and its components. HemaSure's current Products are identified
in the list attached as Exhibit 1 (collectively, the "Products"), and such list
may be updated with mutual agreement from time to time to reflect additional
Products as described above (the "Product List").

                     B. HemaSure and COBE BCT, Inc. ("COBE BCT") entered into an
Exclusive Distribution Agreement on August 14, 1998 (the "Former Distribution
Agreement") whereby (1) COBE BCT became the exclusive distributor, and HemaSure
became the exclusive supplier to COBE BCT, in each case, during the term of the
Former Distribution Agreement, for the Products throughout the world except for
China and the United States, for a term commencing on August 14, 1998, and (2)
HemaSure would supply to COBE BCT certain Products to be incorporated into
medical devices manufactured by COBE BCT for sale to Affiliates of COBE BCT and
to third parties (the "COBE Products").

                     C. The parties hereto desire to amend and restate the
Former Distribution Agreement in its entirety, as provided herein.

                     D. The parties hereto desire that (1) COBE be the exclusive
distributor, and that HemaSure be the exclusive supplier to COBE, pursuant to
this Distribution Agreement for the Products throughout the Territory (as
defined below) for a term commencing on the date hereof (the "Commencement
Date") and continuing throughout the term of this Distribution Agreement set
forth in Article X hereof and (2) HemaSure supply to COBE and its Affiliates
certain Products to be incorporated into the COBE Products.


837580.1

<PAGE>


                                        2


           In consideration of these premises and the mutual promises made
herein by the parties to each other, they agree as follows:


                             ARTICLE 1 - APPOINTMENT

                     1.1 Except as otherwise specifically provided herein,
HemaSure hereby appoints COBE as its exclusive distributor for the Products with
the right to appoint sub-distributors, in the Territory and for the term of this
Distribution Agreement, and COBE hereby accepts this appointment. In return,
COBE appoints HemaSure as its sole and exclusive supplier of the Products, for
the term of this Distribution Agreement, and HemaSure accepts this appointment.
For purposes of this Distribution Agreement, the "Territory" shall be, subject
to the provisions of Sections 10.7 and 10.8, the entire world. Notwithstanding
any provision of this Distribution Agreement to the contrary, HemaSure shall
maintain the exclusive right to distribute products (including, but not limited
to, the Products) made by HemaSure or its Subsidiaries to the American Red Cross
and its Affiliates solely as end-users (subject to COBE's right to sell OEM (as
defined in Section 3.2) products to the American Red Cross and its Affiliates).

                     1.2 All Products shall meet specifications set forth in
Exhibit 1; provided, however, that HemaSure, upon thirty (30) days' prior
written notice specifying the nature of and reasons for such changes, shall have
the right to make any changes in the specifications of the Products to the
extent necessary to satisfy regulatory requirements or to avoid a material
adverse affect on the quality or performance of the Products.

                     1.3 If COBE requests additional Products from HemaSure, or
additional development with respect to a Product, the parties agree to negotiate
in good faith the terms of a development agreement (a "Development Agreement")
for the additional Products or development services. Product development shall
be conducted in accordance with mutually agreed upon plans setting forth the
estimated cost and expense, the proposed specifications for and uses of the
Products and the requirements for and timing of the design, performance, quality
and manufacturability validation, regulatory approval and manufacturing
requirements.  

                     1.4 In connection with any development pursuant to a
Development Agreement, if COBE pays for the complete development of any
additional Products or portions thereof, any improvements to HemaSure's Owned
Intellectual Property resulting therefrom (the "Improvements") shall be COBE's
Owned Intellectual Property, but HemaSure shall have a perpetual, non-exclusive,
world-wide, royalty-free license under such Improvements and Intellectual
Property outside the field of devices that filter blood and its components. If
HemaSure's Owned Intellectual Property existing on the date of any such
Development Agreement is required to practice any such COBE's


837580.1

<PAGE>


                                        3

Owned Intellectual Property, COBE shall have a perpetual non-exclusive,
world-wide, royalty-free license under such HemaSure Owned Intellectual Property
for the term of this Distribution Agreement (as such term may be extended),
limited to the field of devices that filter blood and its components.
Additionally, after the term of this Distribution Agreement, the provisions of
Section 10.10 shall apply to any product sales by COBE utilizing such HemaSure
Owned Intellectual Property, and HemaSure shall be entitled to the 12% royalty
contemplated in Section 10.10. Notwithstanding the above, any final Development
Agreement may set forth terms and conditions which are different than those set
forth in this Section 1.4.

                     1.5 COBE's sole compensation under this Distribution
Agreement shall be the profit it may realize from the resale of the Products.

                     1.6 If Sections 10.7 and 10.8 become applicable, COBE shall
not, without the written consent of HemaSure: (i) seek customers or establish
any branch or maintain any distribution depot for the Products outside the
Territory or (ii) knowingly sell the Products to any customer for use outside
the Territory.

                     1.7 COBE shall be fully responsible for the acts and
conduct of its employees, agents, sub-agents and sub-distributors and shall
indemnify and hold HemaSure harmless from all claims, liabilities and damages
arising out of any negligence or misconduct of COBE or its employees, agents,
sub-agents or sub- distributors.

                     1.8 Neither COBE nor HemaSure shall disclose to any third
party any trade secrets of the other party or any Confidential Information (as
such term is defined in the Confidentiality Agreement) concerning the other
party, its Products or its business. The terms of the Confidentiality Agreement
are incorporated herein by reference thereto in Exhibit 2, as amended in such
Exhibit 2. When this Distribution Agreement terminates, except as otherwise
agreed, each party shall promptly return to the other party all trade secret and
Confidential Information of said other party and shall not disclose or otherwise
use such information for a period of three years after the date of termination.

                     1.9 The following definitions shall apply to this
Distribution Agreement:

           (a) "Affiliate" means, with respect to any specified Person, any

entity; or (iii) the sale or transfer (in one transaction or a series of
transactions) of all or substantially all of the assets of HemaSure, other than

                           ARTICLE 2 - DUTIES OF COBE

           During the term of this Distribution Agreement, COBE shall:
           ----------------------------------------------------------

                     2.1 Use commercially reasonable efforts to market and sell
the Products and develop a profitable market for them in the Territory.

                     2.2 Maintain and utilize such personnel, organization and
facilities as will be competent and adequate to enable COBE to satisfy its
obligations under this Distribution Agreement. 

                     2.3 At least thirty days before the end of each calendar
quarter, prepare and furnish to HemaSure a proposed annual purchase forecast by
month for the following four calendar quarters, specifying the quantities of the
Products which COBE forecasts will be purchased for delivery during each month
of that year; provided, however, that in no event may HemaSure be required to
deliver quantities of any Product during a month which exceed 110% of the
maximum deliveries of such Product to COBE during any earlier calendar month.
All orders for shipment of Products within 30 days from the order shall be
deemed to be firm and non-cancelable.

                     2.4 Purchase from HemaSure and at all times maintain the
minimum inventories of Products to provide adequate service and delivery to
customers in the Territory. COBE shall meet the minimum purchase requirement set
forth in Exhibit 3, attached hereto, unless Exhibit 4 shall be applicable
pursuant to the provisions of Sections 10.7 and 10.8 in which case COBE shall
meet the minimum purchase requirements set forth therein, as the same shall be
amended from time to time. In the event that Exhibit 4 is applicable, the
parties shall meet at least three months before the end of each calendar year
with respect to the matters set forth in Exhibit 4 and negotiate in good faith
the minimum purchase requirements for the following calendar year, provided,
that if they fail to agree by the beginning of the year the aggregate

837580.1

<PAGE>


                                        6

minimum purchase requirements for all Products during that year shall equal 110%
of such aggregate minimum requirements for the preceding year.

                     2.5 Advise HemaSure of inquiries which COBE or any
Affiliates receive from potential customers for the Products outside the
Territory, if applicable, and shall use its commercially reasonable efforts to
transfer to HemaSure all customers who are reasonably likely to use the Products
outside the Territory, if applicable.

                     2.6 Except as otherwise agreed by the parties in writing,
obtain all regulatory approvals, registrations, and listing of Products required
(Food and Drug Administration (the "F.D.A."), C.E., C.S.A., etc.) in the
Territory to make and sell Products incorporated into COBE Products, or certify
that such approvals and registrations have been obtained or are not required,
and comply with all applicable laws, standards, rules and regulations.

                     2.7 Not modify or alter the Products in any way without the
prior written approval of HemaSure.

                     2.8 Indemnify and hold harmless HemaSure and its Affiliates
and customers, and their officers, directors, agents and employees, from and
against losses, claims and damages (including reasonable fees and expenses of
counsel) ("Losses") as they are incurred, but solely to the extent such Losses
arise out of or are related to any claim by a third party that any Product
modifications or specifications requested by COBE on Products sold by COBE
conflict with or infringe upon Intellectual Property owned or licensed by the
third party. An exception to the above is that COBE will not indemnify and hold
harmless HemaSure and its Affiliates for any additional Losses arising from a
determination of willful infringement.

                     2.9 Indemnify and hold harmless HemaSure and its Affiliates
and customers, and their officers, directors, agents and employees, from and
against Losses as they are incurred, solely to the extent such Losses arise out
of or are related to any claim by a third party that any Product has caused
personal injury or other loss to the third party, and only to the extent such
actual or alleged personal injury or loss arises from willful misconduct, gross
negligence, failure to follow HemaSure's written instructions, or alterations of
a Product or Products without HemaSure's written approval. COBE shall maintain
product liability insurance with reputable insurers in such amounts and covering
such risks and on such terms and conditions as are in accordance with normal

                     10.4 COBE may, at its discretion, terminate this
Distribution Agreement for cause immediately upon written notice if:

           (a) HemaSure has failed to supply any Products in quantities greater
than 85% of the minimum amounts forecasted for two of any six consecutive
calendar quarters.

           (b) HemaSure violates the provisions of Section 1. 1.

                     10.5 Notwithstanding the foregoing, HemaSure's sole remedy
in the event COBE fails to meet the minimum purchase requirements of (a) Exhibit
3, if applicable, shall be as set forth under the heading "Consequences of
Exceeding or Failure to Meet Minimum Volume Targets" in Exhibit 3, or (b)
Exhibit 4, if applicable, shall be the remedies set forth in such Exhibit 4;
provided, that with respect to Exhibit 4 COBE may cure any such breach within
the sixty (60) day notice period by ordering sufficient Products to fulfill the
minimum for the quarter during which the sixty (60) day period ends.

                     10.6 Neither HemaSure nor COBE owns or shall be deemed to
own any right of property in this Distribution Agreement.

                     10.7 HemaSure shall have the right to terminate this
Distribution Agreement with respect to the United States of America in the event
of a Change in Control of HemaSure, and, in the event of such termination, the
definition of the "Territory" and the minimum volume purchase requirements of
COBE shall be revised 

837580.1

<PAGE>


                                       17

as provided in Section 10.8 below. In the event that HemaSure desires to
terminate this Distribution Agreement in the United States of America pursuant
to the preceding sentence, HemaSure shall deliver written notice to COBE setting
forth (i) a description of the Change in Control and (ii) the date the
termination process (as contemplated below) shall commence; provided that in no
event shall the date of the commencement of such termination process be less
than 18 months after the Approval Date. The termination process shall be
completed by, and the date of termination of this Distribution Agreement with
respect to the United States of America pursuant to this Section 10.7 shall be,
the first-year anniversary of the date of commencement of the termination
process (as specified in HemaSure's termination notice to COBE). During the
period of the termination process and prior to the termination date with respect
to the United States of America, (i) HemaSure may, by itself or through other
distributors, distribute or co-distribute Products under its own brand name or
any other brand name (other than COBE's brand names) or no brand name to any
Person, (ii) COBE shall not solicit any new customers for Products, other than
such customers as COBE shall have identified to HemaSure in a written schedule
(which schedule shall consist of customers that COBE is then currently in
negotiations with for the sale of Products) delivered to HemaSure not later than
10 business days after COBE's receipt of such notice of termination, (iii) each
of COBE and HemaSure will use their respective best efforts to facilitate an
orderly transition of COBE's business for the sale of Products in the United
States of America on the date of delivery of such termination notice by HemaSure
and (iv) COBE shall not be bound by the second sentence of Section 1.1 and
Section 2.15 with respect to the United States of America.

                     10.8 In the event HemaSure exercises its rights under
Section 10.7, upon the effective date of the termination contemplated thereby,
(i) the Territory shall be the entire world other than the United States of
America and (ii) the minimum purchase requirement shall be as set forth on
Exhibit 4, not Exhibit 3.

                     10.9 In the event of termination of this Distribution
Agreement for any reason, the provisions of Articles 6 and 7 and Sections 1.4,
1.7, 1.8, 2.8, 2.9, 3.8 through 3.12, 10.7 through 10.13 and 13.5 through 13.8
shall nevertheless remain in effect.

                     10.10 If this Distribution Agreement expires by its terms,
or is terminated for any reason, including pursuant to Section 10.7, other than
willful default by COBE, COBE shall have and is hereby granted a non-exclusive,
world-wide perpetual license of HemaSure's Owned Intellectual Property (but only
to the extent such Owned Intellectual Property exists and is in effect as of the
date of the termination) to make, have made, use and sell devices for filtration
of blood and its components, for a royalty, as to any Product (but only in the
Territory) and/or COBE Product (on a world-wide basis) incorporating such
HemaSure Owned Intellectual Property, equal to 12% of the most recent net
purchase price paid by COBE to HemaSure for that Product. The 


837580.1

<PAGE>


                                       18

indemnification by HemaSure set forth in Section 3.10 of this Distribution
Agreement shall not apply to the activities of COBE done pursuant to a license
granted under this Section 10.10.

                     10.11 Notwithstanding Section 10.10, above, if termination
or expiration happens solely as a result of COBE's providing HemaSure notice of
termination at the end of the then-current term under Section 10.1 above, then
the COBE license provided for in Section 10.10 will be a limited time period
license for all Products (except those Products used as a component of COBE's
own products, which shall remain a perpetual license), so as to allow a
commercially reasonable market transition by COBE to other suppliers or
distributors.

                     10.12 Notwithstanding any other provision contained in this
Distribution Agreement, including, without limitation, Section 10.7 of this
Distribution Agreement, upon Termination of this Distribution Agreement for any
reason, in whole or in part, HemaSure shall continue to supply all Products
required by COBE (i) in order to permit COBE to fulfill its obligations under
COBE's then existing third party contracts and (ii) with respect to all of
COBE's existing and future OEM arrangements and products. In the event that
HemaSure should deliver its notice of termination with respect to the United
States of America portion of the Territory pursuant to Section 10.7, COBE shall
not, after receipt of such notification and except as permitted by Section 10.7,
enter into any new contracts for the supply of Products in the United States of
America which would extend beyond the date of the expiration of the termination
process contemplated by Section 10.7.

                     10.13 Within sixty days following the expiration or
termination of this Distribution Agreement, HemaSure shall repurchase from COBE
at the original purchase price any Products delivered to COBE in the sixty days
prior to the expiration or termination of this Distribution Agreement, which
remain in COBE's inventory and which have remaining shelf life and are in good
re-sellable condition.

                     11.1 HemaSure shall not take any action that would result
in the assignment of this Distribution Agreement, in whole or in part, without
the express written consent of COBE, which consent shall not be unreasonably
withheld or delayed. In addition, subject to the terms of this Distribution
Agreement, including, without limitation, Sections 10.7 and 10.8, HemaSure shall
not sell or transfer, in one transaction or a series of transactions, all or
substantially all of the assets of HemaSure unless the acquiror of such assets

Distribution Agreement to an Affiliate and, subject to HemaSure's rights of
termination in Article 10, COBE may assign this Distribution Agreement as a part
of the sale of substantially all of its assets related to its blood filtration
products business.

including its agents and employees. COBE's product liability insurance shall

                      Senior Management Retention Agreement
                      -------------------------------------


Mr. John F. McGuire
c/o HemaSure Inc.
140 Locke Drive
Marlborough, Massachusetts 01752

Dear Mr. McGuire:

    HemaSure Inc. (the "Company") recognizes that, as is the case with many
publicly-held corporations, the possibility of a change in control may exist and
that such possibility, and the uncertainty and questions which it may raise
among key personnel, may result in the departure or distraction of key personnel
to the detriment of the Company, its stockholders and its customers.

    The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

    In order to induce you to remain in its employ, the Company agrees that you
shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" of the
Company (as defined below).

    1. Certain Definitions.
       --------------------

    As used herein, the following terms shall have the following respective
meanings:

         (a) A "Change in Control" shall occur or be deemed to have occurred
only if any of the following events occur: (i) any "person," as such term is
used in Sections 13(d) and 


837899.1
                                       -1-

14(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), (other than the Company, Sepracor Inc.
("Sepracor"), any trustee or other fiduciary holding securities under an
employee benefit plan of the Company, or any corporation owned directly or
indirectly by the stockholders of the Company in substantially the same
proportion as their ownership of stock of the Company) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing more than 50% of the
combined voting power of the Company's then outstanding securities; (ii)
individuals who, as of the date hereof, constitute the Board (as of the date
hereof, the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board, provided that any person becoming a director subsequent
to the date hereof whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board (other than an election or nomination of an
individual whose initial assumption of office is in connection with an actual or
threatened election contest relating to the election of the directors of the
Company, as such terms are used in Rule 14a-11 of Regulation 14A under the
Exchange Act) shall be, for purposes of this Agreement, considered as though
such person were a member of the Incumbent Board; or (iii) the stockholders of
the Company approve a merger or consolidation of the Company with any other
corporation, other than (A) a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) more than 50% of the combined 
voting power of the voting securities of the Company or such surviving entity 
outstanding immediately after such merger or consolidation or (B) a merger or 
consolidation effected to implement a recapitalization of the Company (or 
similar transaction) in which no person (as hereinabove defined), other than a 
person holding more than 50% of the combined voting power of the Company's then 
outstanding securities immediately prior to such 


837899.1
                                       -2-

<PAGE>


recapitalization, acquires more than 50% of
the combined voting power of the Company's then outstanding securities; or (iv)
the stockholders of the Company approve an agreement for the sale of all or
substantially all of the business of the Company through the disposition by the
Company of all or substantially all of the Company's assets.

         (b) A "Potential Change in Control" shall be deemed to have occurred
if:

             (A) the Company enters in an agreement, the consummation of which
     would result in the occurrence of a Change in Control of the Company,

             (B) any person (including the Company and Sepracor) publicly
     announces an intention to take or to consider taking actions which if
     consummated would constitute a Change in Control of the Company; or

             (C) the Board of Directors of the Company adopts a resolution to
     the effect that, for purposes of this Agreement, a Potential Change in
     Control of the Company has occurred.

         2. Term of the Agreement. 
            ---------------------- 

         The term of this Agreement (the "Term") shall commence on as of the
date hereof and shall continue in effect through December 31, 1998; provided,
however, that commencing on

         January 1, 1999 and each January 1 thereafter, the Term shall be
automatically extended for one additional year unless, not later than October 30
of the preceding calendar year, the Company shall have given you written notice
that the Term will not be extended; and provided further that, if a Change in
Control of the Company shall have occurred during the original or extended Term,
this Agreement shall continue in effect for as long as you remain an employee of
HemaSure or any acquirer or successor of HemaSure hereunder. 

         3. Change in Control; Potential Change in Control.
            -----------------------------------------------

Change in Control of the Company during the Term. 

            (b) You agree that, notwithstanding any provision to the contrary in
this Agreement, in the event of a Potential Change in Control of the Company,
you will not voluntarily resign as an employee of the Company until the earliest
of (A) a date which is twelve (12) months after the occurrence of such Potential
Change in Control of the Company or (B) the termination by you of your
employment by reason of Disability as defined in Section 4(b)(i) or for Good
Reason as defined in Section 4(b)(iii).

         4. Employment Status: Termination Following Change in Control.
            -----------------------------------------------------------

            (a) You acknowledge that this Agreement does not constitute a
contract of employment or impose on the Company any obligation to retain you as
an employee and, except as set forth in Section 3(b), this Agreement does not
prevent you from terminating your employment at any time. If your employment
with the Company terminates for any reason and subsequently a Change in Control
shall have occurred, you shall not be entitled to any benefits hereunder. Any
termination of your employment by the Company or by you following a
Change in Control of the Company during the Term shall be communicated by
written notice of termination ("Notice of Termination") to the other party
hereto in accordance with Section 7. The "Date of Termination" shall mean the
effective date of such termination as specified in the Notice of Termination
(provided that no such Notice of Termination shall specify an effective date
less than 10 days or more than 120 days after the date of such Notice of
Termination). 

            (b) Notwithstanding anything to the contrary herein, you shall be
entitled to the benefits provided in Section 5 only if a Change in Control shall
have occurred during the Term and your employment with the Company is
subsequently terminated or terminates after such Change in Control, unless such
termination is (A) because of your death, (B) by the 


837899.1
                                       -4-

<PAGE>


Company for Disability (as defined in Section 4(b)(i)) or Cause (as defined in
Section 4(b)(ii)), or (C) by you within 12 months after a Change in Control
other than for Good Reason (as defined in Section 4(b)(iii)).

                (i) Disability. If, as a result of incapacity due to physical or
mental illness, you shall have been absent from the full-time performance of
your duties with the Company for six (6) consecutive months and, within thirty
(30) days after written notice of termination is given to you, you shall not
have returned to the full-time performance of your duties, your employment may
be terminated for "Disability."

                (ii) Cause. Termination by the Company of your employment for
"Cause" shall mean termination (A) upon your willful and continued failure to
substantially perform your duties with the Company (other than any such failure
resulting from your incapacity due to physical or mental illness or any such
actual or anticipated failure after the issuance of a Notice of Termination by 
you for Good Reason as defined in Section 4(b)(iii)), provided that a written 
demand for substantial performance has been delivered to you by the Company 
specifically identifying the manner in which the Company believes that you have 
not substantially performed your duties and you have not cured such failure 
within 30 days after such demand, or (B) by reason of your willful engaging in 
conduct which is demonstrably and materially injurious to the Company.

                (iii) Good Reason. For purposes of this Agreement, "Good Reason"
shall mean, without your written consent, the occurrence after a Change in
Control of the Company of any of the following circumstances unless, in the case
of paragraphs (A), (C), (D), (F) or (G), such circumstances are fully corrected
prior to the Date of Termination (as defined in Section 4(a)) specified in the
Notice of Termination (as defined in Section 4(a)) given in respect thereof:


837899.1
                                       -5-

<PAGE>


             (A) any significant diminution in your position, duties,
     responsibilities, power, title or office as in effect immediately prior to
     a Change in Control;

             (B) any reduction in your annual base salary as in effect on the
     date hereof or as the same may be increased from time to time;

             (C) the failure by the Company to (i) continue in effect any
     material compensation or benefit plan in which you participate immediately
     prior to the Change in Control, unless an equitable arrangement (embodied
     in an ongoing substitute or alternative plan) has been made with respect to
     such plan, (ii) continue your participation therein (or in such substitute
     or alternative plan) on a basis not materially
     less favorable, both in terms of the amount of benefits provided and the
     level of your participation relative to other participants, as existed at
     the time of the Change in Control or (iii) award cash bonuses to you in
     amounts and in a manner substantially consistent with past practice in
     light of the Company's financial performance; 

             (D) the failure by the Company to continue to provide you with
     benefits substantially similar to those enjoyed by you under any of the
     Company's life insurance, medical, health and accident, or disability plans
     in which you were participating at the time of the Change in Control, the
     taking of any action by the Company which would directly or indirectly
     materially reduce any of such benefits, or the failure by the Company to
     provide you with the number of paid vacation days to which you are entitled
     on the basis of years of service with the Company in accordance with the
     Company's normal vacation policy in effect at the time of the Change in
     Control; 

             (E) any requirement by the Company or of any person in control of
     the Company that the location at which you perform your principal duties
     for the Company be changed to a new location that is not at the United
     States headquarters of the Company or the United States headquarters of the
     division of the Company in which you 

837899.1
                                       -6-

<PAGE>

     perform your assigned duties;

             (F) the failure of the Company to obtain a reasonably satisfactory
     agreement from any successor to assume and agree to perform this Agreement,
     as contemplated in Section 6; or

             (G) any purported termination of your employment which is not
     effected pursuant to a Notice of Termination satisfying the requirements of
     Section 7, which purported termination shall not be effective for purposes
     of this Agreement. 

         5. Compensation Upon Termination. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

            (a) During any period that you fail to perform your full-time duties
with the Company as a result of incapacity due to physical or mental illness,
you shall continue to receive base salary and all other earned compensation at
the rate in effect at the commencement of any such period (offset by all
compensation payable to you under the Company's disability plan or program or
other similar plan during such period) until your employment is terminated
pursuant to Section 4(b)(i) hereof. Thereafter, or in the event your employment
is terminated by reason of death, your benefits shall be determined under the
Company's long-term disability, retirement, insurance and other compensation
programs then in effect in accordance with the terms of such programs.

            (b) If your employment shall be terminated by the Company for Cause
or by you other than for Good Reason within 12 months after a Change in Control,
the Company shall pay you your full base salary and all other compensation
through the Date of Termination at the rate in effect at the time the Notice of
Termination is given, plus all other amounts to which you 


837899.1
                                       -7-

<PAGE>

are entitled under any compensation plan of the Company at the time such
payments are due, and the Company shall have no further obligations to you under
this Agreement.

            (c) You shall be entitled to the benefits listed below in
Subsections (c)(i) through (c)(iii) below if your employment with the Company is
terminated (x) by the Company (other than for Cause, Disability or your death)
after a Change in Control, (y) by you for Good Reason within 12 months after a
Change in Control or (z) by you for any reason or no reason more than 12 months
after a Change in Control. Notwithstanding any provision to the contrary herein,
in the event a Change in Control occurs as a result of a sale of all or
substantially all of the business of the Company pursuant to a merger, sale of
assets or otherwise and you are entitled to the Severance Payments (as defined
below), the Severance Payments payable to you shall be reduced to the extent
that the net present value of the Severance Payments (as then reasonably
determined by the Board of Directors of the Company) are greater than 5% of the
Gross Proceeds. For purposes of this Agreement "Gross Proceeds" shall equal the
gross consideration paid by an acquirer or acquirers of the Company in
connection with the sale of all or substantially all of the business of the
Company pursuant to a merger, sales of assets or otherwise. 

                (i) the Company shall pay to you (A) your full base salary and
all other compensation through the Date of Termination at the rate in effect at
the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any 
earnings credited on such amounts under such plan;


837899.1
                                       -8-

<PAGE>

                (ii) the Company will pay as severance pay to you, in
twenty-four (24) equal monthly installments, beginning at the end of the first
full month subsequent to the Date of Termination, an aggregate amount equal to
the sum of (A) 300% of the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, plus (B) 300% of the aggregate cash bonuses paid
or awarded to you in respect of the four fiscal quarters preceding the Date of
Termination (together with the payments provided in paragraph (iii) below, the
"Severance Payments"); and

                (iii) for a thirty-six (36) month period after such termination,
the Company shall arrange to provide you with life, disability, dental, accident
and group health insurance benefits substantially similar to those which you
were receiving immediately prior to the Notice of Termination. Notwithstanding
the foregoing, the Company shall not provide any benefit otherwise receivable by
you pursuant to this paragraph (iii) if an equivalent benefit is actually
received by you during the thirty-six (36) month period following your
termination, and any such benefit actually received by you shall be reported to
the Company.

            (d) Severance Payments under this Agreement shall be made without
regard to whether the deductibility of such payments (or any other payments to
or for your benefit) would be limited or precluded by Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code") and without regard to
whether such payments (or any other payments) would subject you to the federal
excise tax levied on certain "excise parachute payments"
under Section 4999 of the Code; provided, that if the total of all payments to
or for your benefit, after deduction of all federal taxes (including the tax set
forth in Section 4999 of the Code, if applicable) with respect to such payments
(the "total after-tax payments"), would be increased by the limitation or
elimination of any payment under this Agreement, amounts payable under this
Agreement shall be reduced to the extent, and only to the extent, necessary to
maximize the total 


837899.1
                                       -9-

<PAGE>


after-tax payments. The determination as to whether and to
what extent payments under this agreement are required to be reduced in
accordance with the preceding sentence shall be made by agreement between you
and the independent public accounting firm of the Company. To the extent that
any elimination or reduction of payments is made in accordance with this Section
5(d), the determination as to which payments shall be eliminated or reduced
shall be made by you. 

            (e) The payments provided for in Subsections 5(b) and (c) shall be
made not later than the fifth day following the Date of Termination, unless
otherwise specified; provided, however, that, if the amounts of such payments
cannot be finally determined on or before such day, the Company shall pay to you
on such day an estimate, as determined in good faith by the Company, of the
minimum amount of such payments and shall pay the remainder of such payments
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code) as soon as the amount thereof can be determined but in no event later than
the thirtieth day after the Date of Termination. In the event that the amount of
the estimated payments exceeds the amount subsequently determined to have been
due, such excess shall constitute a loan by the Company to you, payable on the
fifth day after demand by the Company (together with interest at the rate
provided in Section 1274(b)(2)(B) of the Code).

            (f) Except as provided in the second sentence of Subsection
5(c)(iii) hereof, you shall not be required to mitigate the amount of any
payment provided for in this Section 5 by seeking other employment or otherwise,
nor shall the amount of any payment or benefit provided for in this Section 5 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise. 

         6. Successors; Binding Agreement.
            ------------------------------

            (a) The Company will require any successor (whether direct or
indirect, by 


837899.1
                                      -10-

<PAGE>


purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to terminate your employment, except that
for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Date of Termination. As used in
this Agreement, Company shall mean the Company as defined above and any
successor to its business or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise. 

            (b) This Agreement shall inure to the benefit of and be enforceable
by your personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If you should die while
any amount would still be payable to you hereunder if you had continued to live,
all such amounts, unless otherwise provided herein,
shall be paid in accordance with the terms of this Agreement to your devisee,
legatee or other designee or if there is no such designee, to your estate. 

         7. Notice. 
            ------

            For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the
Chairman of the Board of Directors of the Company, at 111 Locke Drive,
Marlborough, Massachusetts 01752, and to you at the address shown above or to
such other address as either the Company or you may have furnished to the other
in writing in accordance herewith, except that notice of change of address shall
be effective only upon receipt.

            (a) The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

            (b) The validity, interpretation, construction and performance of
this Agreement shall be governed by the laws of the Commonwealth of
Massachusetts.

            (c) No waiver by you at any time of any breach of, or compliance
with, any provision of this Agreement to be performed by the Company shall be
deemed a waiver of that or any other provision at any subsequent time.

            (d) This Agreement may be executed in counterparts, each of which
shall be deemed to be an original but both of which together will constitute one
and the same instrument.

            (e) Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law. 

            (f) This Agreement sets forth the entire agreement of the parties

hereto in respect of the subject matter contained herein is hereby terminated
and cancelled.

         If this letter sets forth our agreement on the subject matter hereof,
kindly sign and return to the Company the enclosed copy of this letter, which

                      Senior Management Retention Agreement
                      -------------------------------------


Mr. James B. Murphy
c/o HemaSure Inc.
140 Locke Drive
Marlborough, Massachusetts 01752

Dear Mr. Murphy:

         HemaSure Inc. (the "Company") recognizes that, as is the case with many
publicly-held corporations, the possibility of a change in control may exist and
that such possibility, and the uncertainty and questions which it may raise
among key personnel, may result in the departure or distraction of key personnel
to the detriment of the Company, its stockholders and its customers.

         The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing,
circumstances arising from the possibility of a change in control of the
Company.

         In order to induce you to remain in its employ, the Company agrees that
you shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" of the
Company (as defined below).

         1. Certain Definitions. As used herein, the following terms shall have
the following respective meanings:

            (a) A "Change in Control" shall occur or be deemed to have occurred
only if any of the following events occur: (i) any "person," as such term is
used in Sections 13 (d) and
837907.1

<PAGE>



14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
(other than the Company, Sepracor Inc. ("Sepracor"), any trustee or other
fiduciary holding securities under an employee benefit plan of the Company, or
any corporation owned directly or indirectly by the stockholders of the Company
in substantially the same proportion as their ownership of stock of the Company)
is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Company representing
more than 50% of the combined voting power of the Company's then outstanding
securities; (ii) individuals who, as of the date hereof, constitute the Board
(as of the date hereof, the "Incumbent Board") cease for any reason to
constitute at least a majority of the Board, provided that any person becoming a
director subsequent to the date hereof whose election, or nomination for
election by the Company's stockholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board (other than an
election or nomination of an individual whose initial assumption of office is in
connection with an actual or threatened election contest relating to the
election of the directors of the Company, as such terms are used in Rule 14a-11
of Regulation 14A under the Exchange Act) shall be, for purposes of this
Agreement, considered as though such person were a member of the Incumbent
Board; or (iii) the stockholders of the Company approve a merger or
consolidation of the Company with any other corporation, other than (A) a merger
or consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than 50% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (B) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
person (as hereinabove defined), other than a person holding more than 50% of
the combined voting power of the Company's then outstanding securities
immediately prior to such

837907.1
                                        2

<PAGE>



recapitalization, acquires more than 50% of the combined voting power of the
Company's then outstanding securities; or (iv) the stockholders of the Company
approve an agreement for the sale of all or substantially all of the business of
the Company through the disposition by the Company of all or substantially all
of the Company's assets.

            (b) A "Potential Change in Control" shall be deemed to have occurred
if:

                (A) the Company enters in an agreement, the consummation of
which would result in the occurrence of a Change in Control of the Company,

                (B) any person (including the Company and Sepracor) publicly
announces an intention to take or to consider taking actions which if
consummated would constitute a Change in Control of the Company; or

                (C) the Board of Directors of the Company adopts a resolution to
the effect that, for purposes of this Agreement, a Potential Change in Control
of the Company has occurred.

         2. Term of the Agreement.

         The term of this Agreement (the "Term") shall commence on as of the
date hereof and shall continue in effect through December 31, 1998; provided,
however, that commencing on January 1, 1999 and each January 1 thereafter, the
Term shall be automatically extended for one additional year unless, not later
than October 30 of the preceding calendar year, the Company shall have given you
written notice that the Term will not be extended; and provided further that, if
a Change in Control of the Company shall have occurred during the original or
extended Term, this Agreement shall continue in effect for as long as you remain
an employee of HemaSure or any acquirer or successor of HemaSure hereunder.

         3. Change in Control; Potential Change in Control.

            (a) No benefits shall be payable under this Agreement unless there
has been a 

837907.1
                                        3

<PAGE>


Change in Control of the Company during the Term.

            (b)    You agree that, notwithstanding any provision to the contrary
                   in this Agreement, in the event of a Potential Change in
                   Control of the Company, you will not voluntarily resign as an
                   employee of the Company until the earliest of (A) a date
                   which is twelve (12) months after the occurrence of such
                   Potential Change in Control of the Company or (B) the
                   termination by you of your employment by reason of Disability
                   as defined in Section 4(b)(i) or for Good Reason as defined
                   in Section 4(b)(iii).

         4. Employment Status; Termination Following Change in Control.

            (a) You acknowledge that this Agreement does not constitute a
contract of employment or impose on the Company any obligation to retain you as
an employee and, except as set forth in Section 3(b), this Agreement does not
prevent you from terminating your employment at any time. If your employment
with the Company terminates for any reason and subsequently a Change in Control
shall have occurred, you shall not be entitled to any benefits hereunder. Any
termination of your employment by the Company or by you following a Change in
Control of the Company during the Term shall be communicated by written notice
of termination ("Notice of Termination") to the other party hereto in accordance
with Section 7. The "Date of Termination" shall mean the effective date of such
termination as specified in the Notice of Termination (provided that no such
Notice of Termination shall specify an effective date less than 10 days or more
than 120 days after the date of such Notice of Termination).

            (b) Notwithstanding anything to the contrary herein, you shall be
entitled to the benefits provided in Section 5 only if a Change in Control shall
have occurred during the Term and your employment with the Company is
subsequently terminated or terminates after such Change in Control, unless such
termination is (A) because of your death, (B) by the

837907.1
                                        4

<PAGE>



Company for Disability, (as defined in Section 4(b)(i)) or Cause (as defined in
Section 4(b)(ii)), or (C) by you within 12 months after a Change in Control
other than for Good Reason (as defined in Section 4(b)(iii)).

                (i) Disability. If, as a result of incapacity due to physical or
mental illness, you shall have been absent from the full-time performance of
your duties with the Company for six (6) consecutive months and, within thirty
(30) days after written notice of termination is given to you, you shall not
have returned to the full-time performance of your duties, your employment may
be terminated for "Disability."

                (ii) Cause. Termination by the Company of your employment for
"Cause" shall mean termination (A) upon your willful and continued failure to
substantially perform your duties with the Company (other than any such failure
resulting from your incapacity due to physical or mental illness or any such
actual or anticipated failure after the issuance of a Notice of Termination by
you for Good Reason as defined in Section 4(b)(iii)), provided that a written
demand for substantial performance has been delivered to you by the Company
specifically identifying the manner in which the Company believes that you have
not substantially performed your duties and you have not cured such failure
within 30 days after such demand, or (B) by reason of your willful engaging in
conduct which is demonstrably and materially injurious to the Company.

                (iii) Good Reason. For purposes of this Agreement, "Good Reason"
shall mean, without your written consent, the occurrence after a Change in
Control of the Company of any of the following circumstances unless, in the
case of paragraphs (A), (C), (D), (F) or (G), such circumstances are fully
corrected prior to the Date of Termination (as defined in Section 4(a))
specified in the Notice of Termination (as defined in Section 4(a)) given in
respect thereof:

                (A) any significant diminution in your position, duties,
responsibilities, power, title or office as in effect immediately prior to a
Change in Control;

                (B) any reduction in your annual base salary as in effect on
the date hereof or as the same may be increased from time to time;

                (C) the failure by the Company to (i) continue in effect any
material compensation or benefit plan in which vou participate immediately prior
to the Change in Control, unless an equitable arrangement (embodied in an
ongoing substitute or alternative plan) has been made with respect to such plan,
(ii) continue your participation therein (or in such substitute or alternative
plan) on a basis not materially less favorable, both in terms of the amount of
benefits provided and the level of your participation relative to other
participants, as existed at the time of the Change in Control or (iii) award
cash bonuses to you in amounts and in a manner substantially consistent with
past practice in light of the Company's financial performance;

                (D) the failure by the Company to continue to provide you with
benefits substantially similar to those enjoyed by you under any of the
Company's life insurance, medical, health and accident, or disability plans in
which you were participating at the time of the Change in Control, the taking of
any action by the Company which would directly or indirectly materially reduce
any of such benefits, or the failure by the Company to provide you with the
number of paid vacation days to which you are entitled on the basis of years of
service with the Company in accordance with the Company's normal vacation policy
in effect at the time of the Change in Control;

                (E) any requirement by the Company or of any person in control
of the Company that the location at which you perform your principal duties for
the Company be changed to a new location that is not at the United States
headquarters of the Company or the United States headquarters of the division
of the Company in which you

837907.1
                                        6

<PAGE>



perform your assigned duties;

                (F) the failure of the Company to obtain a reasonably
satisfactory agreement from any successor to assume and agree to perform this
Agreement, as contemplated in Section 6; or

                (G) any purported termination of your employment which is not
effected pursuant to a Notice of Termination satisfying the requirements of
Section 7, which purported termination shall not be effective for purposes of
this Agreement.

         5. Compensation Upon Termination. Following a Change in Control of the
Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

            (a) During any period that you fail to perform your full-time duties
with the Company as a result of incapacity due to physical or mental illness,
you shall continue to receive base salary and all other earned compensation at
the rate in effect at the commencement of any such period (offset by all
compensation payable to you under the Company's disability plan or program or
other similar plan during such period) until your employment is terminated
pursuant to Section 4(b)(i) hereof. Thereafter, or in the event your employment
is terminated by reason of death, your benefits shall be determined under the
Company's long-term disability, retirement, insurance and other compensation
programs then in effect in accordance with the terms of such programs.

            (b) If your employment shall be terminated by the Company for Cause
or by you other than for Good Reason within 12 months after a Change in Control,
the Company shall pay you your full base salary and all other compensation
through the Date of Termination at the rate in effect at the time the Notice of
Termination is given, plus all other amounts to which you

837907.1
                                        7

<PAGE>



are entitled under any compensation plan of the Company at the time such
payments are due, and the Company shall have no further obligations to you under
this Agreement.

            (c) You shall be entitled to the benefits listed below in
Subsections (c)(i) through (c)(iii) below if your employment with the Company is
terminated (x) by the Company (other than for Cause, Disability or your death)
after a Change in Control, (y) by you for Good Reason within 12 months after a
Change in Control or (z) by you for any reason or no reason more than 12 months
after a Change in Control. Notwithstanding any provision to the contrary herein,
in the event a Change in Control occurs as a result of a sale of all or
substantially all of the business of the Company pursuant to a merger, sale of
assets or otherwise and you are entitled to the Severance Payments (as defined
below), the Severance Payments payable to you shall be reduced to the extent
that the net present value of the Severance Payments (as then reasonably
determined by the Board of Directors of the Company) are greater than 5% of the
Gross Proceeds. For purposes of this Agreement "Gross Proceeds" shall equal the
gross consideration paid by an acquirer or acquirers of the Company in
connection with the sale of all or substantially all of the business of the
Company pursuant to a merger, sales of assets or otherwise.

            (i) the Company shall pay to you (A) your full base salary and all
other compensation through the Date of Termination at the rate in effect at the
time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;

837907.1
                                        8

<PAGE>



                (ii) the Company will pay as severance pay to you, in
twenty-four (24) equal monthly installments, beginning at the end of the first
full month subsequent to the Date of Termination, an aggregate amount equal to
the sum of (A) 200% of the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, plus (B) 200% of the aggregate cash bonuses paid
or awarded to you in respect of the four fiscal quarters preceding the Date of
Termination (together with the payments provided in paragraph (iii) below, the
"Severance Payments"); and

                (iii) for a thirty-six (36) month period after such termination,
the Company shall arrange to provide you with life, disability, dental, accident
and group health insurance benefits substantially similar to those which you
were receiving immediately prior to the Notice of Termination. Notwithstanding
the foregoing, the Company shall not provide any benefit otherwise receivable by
you pursuant to this paragraph (iii) if an equivalent benefit is actually
received by you during the thirty-six (36) month period following your
termination, and any such benefit actually received by you shall be reported to
the Company.

         (d) Severance Payments under this Agreement shall be made without
regard to whether the deductibility of such payments (or any other payments to
or for your benefit) would be limited or precluded by Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code") and without regard to
whether such payments (or any other payments) would subject you to the federal
excise tax levied on certain "excise parachute payments" under Section 4999 of
the Code; provided, that if the total of all payments to or for your benefit,
after deduction of all federal taxes (including the tax set forth in Section
4999 of the Code, if applicable) with respect to Such payments (the "total
after-tax payments"), would be increased by the limitation or elimination of any
payment under this Agreement, amounts payable under this Agreement shall be
reduced to the extent, and only to the extent, necessary to maximize the total

837907.1
                                        9

<PAGE>



after-tax payments. The determination as to whether and to what extent payments
under this agreement are required to be reduced in accordance with the preceding
sentence shall be made by agreement between you and the independent public
accounting firm of the Company. To the extent that any elimination or reduction
of payments is made in accordance with this Section 5(d), the determination as
to which payments shall be eliminated or reduced shall be made by you.

            (e) The payments provided for in Subsections 5(b) and (c) shall be
made not later than the fifth day following the Date of Termination, unless
otherwise specified; provided, however, that, if the amounts of such payments
cannot be finally determined on or before such day, the Company shall pay you on
such day an estimate, as determined in good faith by the Company, of the minimum
amount of such payments and shall pay the remainder of such payments (together
with interest at the rate provided in Section 1274(b)(2)(B) of the Code) as soon
as the amount thereof can be determined but in no event later than the thirtieth
day after the Date of Termination. In the event that the amount of the estimated
payments exceeds the amount subsequently determined to have been due, such
excess shall constitute a loan by the Company to you, payable on the fifth day
after demand by the Company (together with interest at the rate in Section
1274(b)(2)(B) of the Code).

            (f) Except as provided in the second sentence of Subsection
5(c)(iii) hereof, you shall not be required to mitigate the amount of any
payment provided for in this Section 5 by seeking other employment or otherwise,
nor shall the amount of any payment or benefit provided for in this Section 5 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

         6. Successors; Binding Agreement.

            (a) The Company will require any successor (whether direct or
indirect, by 

837907.1
                                       10

<PAGE>



purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company expressly to assume and agree to perform this
Agreement to the same extent that the Company would be required to perform it if
no such succession had taken place. Failure of the Company to obtain an
assumption of this Agreement at or prior to the effectiveness of any succession
shall be a breach of this Agreement and shall constitute Good Reason if you
elect to terminate your employment, except that for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination. As used in this Agreement, Company shall mean
the Company as defined above and any successor to its business or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

            (b) This Agreement shall inure to the benefit of and be enforceable
by your personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If you should die while
any amount would still be payable to you hereunder if you had continued to live,
all such amounts, unless otherwise provided herein, shall be paid in accordance 
with the terms of this Agreement to your devisee, legatee or other designee or 
if there is no such designee, to your estate.

         7. Notice. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the
Chairman of the Board of Directors of the Company, at 111 Locke Drive,
Marlborough, Massachusetts 01752, and to you at the address shown above or to
such other address as either the Company or you may have furnished to the other
in writing in accordance herewith, except that notice of change of address shall
be effective only upon receipt.

         8. Miscellaneous.

            (a) The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

            (b) The validity, interpretation, construction and performance of
this Agreement shall be governed by the laws of the Commonwealth of
Massachusetts.

            (c) No waiver by you at any time of any breach of, or compliance
with, any provision of this Agreement to be performed by the Company shall be
deemed a waiver of that or any other provision at any subsequent time.

            (d) This Agreement may be executed in counterparts, each of which
shall be deemed to be an original but both of which together will constitute one
and the same instrument.

            (e) Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law.

            (f) This Agreement sets forth the entire agreement of the parties

prior agreements, promises, covenants, arrangements, communications,
representations or warranties, whether oral or written, by any officer, employee
or representative of any party hereto; and any prior agreement of the parties
hereto in respect of the subject matter contained herein is hereby terminated
and cancelled.

will then constitute our agreement on this subject.

                                   Sincerely,

                      Senior Management Retention Agreement


Mr. Peter C. Sutcliffe
c/o HemaSure Inc.
140 Locke Drive
Marlborough, Massachusetts  01752

Dear Mr. Sutcliffe:

         HemaSure Inc. (the "Company") recognizes that, as is the case with many
publicly-held corporations, the possibility of a change in control may exist and
that such possibility, and the uncertainty and questions which it may raise
among key personnel, may result in the departure or distraction of key personnel
to the detriment of the Company, its stockholders and its customers.

         The Board of Directors of the Company (the "Board") has determined that
appropriate steps should be taken to reinforce and encourage the continued
attention and dedication of the Company's key personnel, including yourself, to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of the
Company.

         In order to induce you to remain in its employ, the Company agrees that
you shall receive the severance benefits set forth in this letter agreement (the
"Agreement") in the event your employment with the Company is terminated under
the circumstances described below subsequent to a "Change in Control" of the
Company (as defined below).

         1.        Certain Definitions.

         As used herein, the following terms shall have the following respective
meanings:

               (a) A "Change in Control" shall occur or be deemed to have
occurred only if any of the following events occur: (i) any "person," as such
term is used in Sections 13(d) and


837921.1

<PAGE>


14(d) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), (other than the Company, Sepracor Inc.
("Sepracor"), any trustee or other fiduciary holding securities under an
employee benefit plan of the Company, or any corporation owned directly or
indirectly by the stockholders of the Company in substantially the same
proportion as their ownership of stock of the Company) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing more than 50% of the
combined voting power of the Company's then outstanding securities; (ii)
individuals who, as of the date hereof, constitute the Board (as of the date
hereof, the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board, provided that any person becoming a director subsequent
to the date hereof whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board (other than an election or nomination of an
individual whose initial assumption of office is in connection with an actual or
threatened election contest relating to the election of the directors of the
Company, as such terms are used in Rule 14a-11 of Regulation 14A under the
Exchange Act) shall be, for purposes of this Agreement, considered as though
such person were a member of the Incumbent Board; or (iii) the stockholders of
the Company approve a merger or consolidation of the Company with any other
corporation, other than (A) a merger or consolidation which
would result in the voting securities of the Company outstanding immediately
prior thereto continuing to represent (either by remaining outstanding or by
being converted into voting securities of the surviving entity) more than 50% of
the combined voting power of the voting securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation or
(B) a merger or consolidation effected to implement a recapitalization of the
Company (or similar transaction) in which no person (as hereinabove defined),
other than a person holding more than 50% of the combined voting power of the
Company's then outstanding securities immediately prior to such


837921.1
                                       -2-

<PAGE>

recapitalization, acquires more than 50% of the combined voting power of the
Company's then outstanding securities; or (iv) the stockholders of the Company
approve an agreement for the sale of all or substantially all of the business of
the Company through the disposition by the Company of all or substantially all
of the Company's assets.

               (b) A "Potential Change in Control" shall be deemed to have
occurred if:

                    (A) the Company enters in an agreement, the consummation of
which would result in the occurrence of a Change in Control of the Company;

                    (B) any person (including the Company and Sepracor) publicly
announces an intention to take or to consider taking actions which if
consummated would constitute a Change in Control of the Company; or 

                    (C) the Board of Directors of the Company adopts a
resolution to the effect that, for purposes of this Agreement, a Potential
Change in Control of the Company has occurred.

           2. Term of the Agreement.

           The term of this Agreement (the "Term") shall commence on as of the
date hereof and shall continue in effect through December 31, 1998; provided,
however, that commencing on January 1, 1999 and each January 1 thereafter, the
Term shall be automatically extended for one additional year unless, not later
than October 30 of the preceding calendar year, the Company shall have given you
written notice that the Term will not be extended; and provided further that, if
a Change in Control of the Company shall have occurred during the original or
extended Term, this Agreement shall continue in effect for as long as you remain
an employee of HemaSure or any acquirer or successor of HemaSure hereunder.

           3.        Change in Control; Potential Change in Control.

               (a) No benefits shall be payable under this Agreement unless
there has been a 



837921.1
                                       -3-

<PAGE>


Change in Control of the Company during the Term.

               (b) You agree that, notwithstanding any provision to the contrary
in this Agreement, in the event of a Potential Change in Control of the Company,
you will not voluntarily resign as an employee of the Company until the earliest
of (A) a date which is twelve (12) months after the occurrence of such Potential
Change in Control of the Company or (B) the termination by you of your
employment by reason of Disability as defined in Section 4(b)(i) or for Good
Reason as defined in Section 4(b)(iii).

           4.        Employment Status; Termination Following Change in Control.

               (a) You acknowledge that this Agreement does not constitute a
contract of employment or impose on the Company any obligation to retain you as
an employee and, except as set forth in Section 3(b), this Agreement does not
prevent you from terminating your employment at any time. If your employment
with the Company terminates for any reason and subsequently a Change in Control
shall have occurred, you shall not be entitled to any benefits hereunder. Any
termination of your employment by the Company or by you following a Change in
Control of the Company during the Term shall be communicated by written notice
of termination ("Notice of Termination") to the other party hereto in accordance
with Section 7. The "Date of Termination" shall mean the effective date of such
termination as specified in the Notice of Termination (provided that no such
Notice of Termination shall specify an effective date less than 10 days or more
than 120 days after the date of such Notice of Termination).

               (b) Notwithstanding anything to the contrary herein, you shall be
entitled to the benefits provided in Section 5 only if a Change in Control shall
have occurred during the Term and your employment with the Company is
subsequently terminated or terminates after such Change in Control, unless such
termination is (A) because of your death, (B) by the 


837921.1
                                       -4-

<PAGE>



Company for Disability (as
defined in Section 4(b)(i)) or Cause (as defined in Section 4(b)(ii)), or (C) by
you within 12 months after a Change in Control other than for Good Reason (as
defined in Section 4(b)(iii)).

                    (i) Disability. If, as a result of incapacity due to
physical or mental illness, you shall have been absent from the full-time
performance of your duties with the Company for six (6) consecutive months and,
within thirty (30) days after written notice of termination is given to you, you
shall not have returned to the full-time performance of your duties, your
employment may be terminated for "Disability."

                    (ii) Cause. Termination by the Company of your employment
for "Cause" shall mean termination (A) upon your willful and continued failure
to substantially perform your duties with the Company (other than any such
failure resulting from your incapacity due to physical or mental illness or any
such actual or anticipated failure after the issuance of a Notice of Termination
by you for Good Reason as defined in Section 4(b)(iii)), provided that a written
demand for substantial performance has been delivered to you by the Company
specifically identifying the manner in which the Company believes that you have
not substantially performed your duties and you have not cured such failure
within 30 days after such demand, or (B) by reason of your willful engaging in
conduct which is demonstrably and materially injurious to the Company.

                    (iii) Good Reason. For purposes of this Agreement, "Good
Reason" shall mean, without your written consent, the occurrence after a Change
in Control of the Company of any of the following circumstances unless, in the
case of paragraphs (A), (C), (D), (F) or (G), such circumstances are fully
corrected prior to the Date of Termination (as defined in Section 4(a))
specified in the Notice of Termination (as defined in Section 4(a)) given in
respect thereof:

<PAGE>

                         (A) any significant diminution in your position,
duties, responsibilities, power, title or office as in effect immediately prior
to a Change in Control;

                         (B) any reduction in your annual base salary as in
effect on the date hereof or as the same may be increased from time to time;

                         (C) the failure by the Company to (i) continue in
effect any material compensation or benefit plan in which you participate
immediately prior to the Change in Control, unless an equitable arrangement
(embodied in an ongoing substitute or alternative plan) has been made with
respect to such plan, (ii) continue your participation therein (or in such
substitute or alternative plan) on a basis not materially less favorable, both
in terms of the amount of benefits provided and the level of your participation
relative to other participants, as existed at the time of the Change in Control
or (iii) award cash bonuses to you in amounts and in a manner substantially
consistent with past practice in light of the Company's financial performance;

                         (D) the failure by the Company to continue to provide
you with benefits substantially similar to those enjoyed by you under any of the
Company's life insurance, medical, health and accident, or disability plans in
which you were participating at the time of the Change in Control, the taking of
any action by the Company which would directly or indirectly materially reduce
any of such benefits, or the failure by the Company to provide you with the
number of paid vacation days to which you are entitled on the basis of years of
service with the Company in accordance with the Company's normal vacation policy
in effect at the time of the Change in Control;

                         (E) any requirement by the Company or of any person in
control of the Company that the location at which you perform your principal
duties for the Company be changed to a new location that is not at the United
States headquarters of the Company or the United States headquarters of the
division of the Company in which you 

837921.1
                                       -6-

<PAGE>

perform your assigned duties;

                         (F) the failure of the Company to obtain a reasonably
satisfactory agreement from any successor to assume and agree to perform this
Agreement, as contemplated in Section 6; or

                         (G) any purported termination of your employment which
is not effected pursuant to a Notice of Termination satisfying the requirements
of Section 7, which purported termination shall not be effective for purposes of
this Agreement.

           5. Compensation Upon Termination. Following a Change in Control of
the Company, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the Term:

               (a) During any period that you fail to perform your full-time
duties with the Company as a result of incapacity due to physical or mental
illness, you shall continue to receive base salary and all other earned
compensation at the rate in effect at the commencement of any such period
(offset by all compensation payable to you under the Company's disability plan
or program or other similar plan during such period) until your employment is
terminated pursuant to Section 4(b)(i) hereof. Thereafter, or in the event your
employment is terminated by reason of death, your benefits shall be determined
under the Company's long-term disability, retirement, insurance and other
compensation programs then in effect in accordance with the terms of such
programs.

               (b) If your employment shall be terminated by the Company for
Cause or by you other than for Good Reason within 12 months after a Change in
Control, the Company shall pay you your full base salary and all other
compensation through the Date of Termination at the rate in effect at the time
the Notice of Termination is given, plus all other amounts to which you 


837921.1
                                       -7-

<PAGE>

are entitled under any compensation plan of the Company at the time such
payments are due, and the Company shall have no further obligations to you under
this Agreement.

               (c) You shall be entitled to the benefits listed below in
Subsections (c)(i) through (c)(iii) below if your employment with the Company is
terminated (x) by the Company (other than for Cause, Disability or your death)
after a Change in Control, (y) by you for Good Reason within 12 months after a
Change in Control or (z) by you for any reason or no reason more than 12 months
after a Change in Control. Notwithstanding any provision to the contrary herein,
in the event a Change in Control occurs as a result of a sale of all or
substantially all of the business of the Company pursuant to a merger, sale of
assets or otherwise and you are entitled to the Severance Payments (as defined
below), the Severance Payments payable to you shall be reduced to the extent
that the net present value of the Severance Payments (as then reasonably
determined by the Board of Directors of the Company) are greater than 5% of the
Gross Proceeds. For purposes of this Agreement "Gross Proceeds" shall equal the
gross consideration paid by an acquirer or acquirers of the Company in
connection with the sale of all or substantially all of the business of the
Company pursuant to a merger, sale of assets or otherwise: 

                    (i) the Company shall pay to you (A) your full base salary
and all other compensation through the Date of Termination at the rate in effect
at the time the Notice of Termination is given, no later than the full fifth day
following the Date of Termination, plus all other amounts to which you are
entitled under any compensation plan of the Company at the time such payments
are due and (B) if you so elect, in lieu of your right to continue to receive
deferred compensation under any deferred compensation plan of the Company then
in effect, no later than the fifth full day following the Date of Termination, a
lump-sum amount, in cash, equal to the deferred amounts together with any
earnings credited on such amounts under such plan;



837921.1
                                       -8-

<PAGE>


                    (ii) the Company will pay as severance pay to you, in
twenty-four (24) equal monthly installments, beginning at the end of the first
full month subsequent to the Date of Termination, an aggregate amount equal to
the sum of (A) 200% of the higher of (x) your annual base salary in effect on
the Date of Termination or (y) your annual base salary in effect immediately
prior to the Change in Control, plus (B) 200% of the aggregate cash bonuses paid
or awarded to you in respect of the four fiscal quarters preceding the Date of
Termination (together with the payments provided in paragraph (iii) below, the
"Severance Payments"); and

                    (iii) for a thirty-six (36) month period after such
termination, the Company shall arrange to provide you with life, disability,
dental, accident and group health insurance benefits substantially similar to
those which you were receiving immediately prior to the Notice of Termination.
Notwithstanding the foregoing, the Company shall not provide any benefit
otherwise receivable by you pursuant to this paragraph (iii) if an equivalent
benefit is actually received by you during the thirty-six (36) month period
following your termination, and any such benefit actually received by you shall
be reported to the Company. 

               (d) Severance Payments under this Agreement shall be
made without regard to whether the deductibility of such payments (or any other
payments to or for your benefit) would be limited or precluded by Section 280G
of the Internal Revenue Code of 1986, as amended (the "Code") and without regard
to whether such payments (or any other payments) would subject you to the
federal excise tax levied on certain "excise parachute payments" under Section
4999 of the Code; provided, that if the total of all payments to or for your
benefit, after deduction of all federal taxes (including the tax set forth in
Section 4999 of the Code, if applicable) with respect to such payments (the
"total after-tax payments"), would be increased by the limitation or elimination
of any payment under this Agreement, amounts payable under this Agreement shall
be reduced to the extent, and only to the extent, necessary to maximize the
total


837921.1
                                       -9-

<PAGE>

after-tax payments. The determination as
to whether and to what extent payments under this Agreement are required to be
reduced in accordance with the preceding sentence shall be made by agreement
between you and the independent public accounting firm of the Company. To the
extent that any elimination or reduction of payments is made in accordance with
this Section 5(d), the determination as to which payments shall be eliminated or
reduced shall be made by you.

               (e) The payments provided for in Subsections 5(b) and (c) shall
be made not later than the fifth day following the Date of Termination, unless
otherwise specified; provided, however, that, if the amounts of such payments
cannot be finally determined on or before such day, the Company shall pay to you
on such day an estimate, as determined in good faith by the Company, of the
minimum amount of such payments and shall pay the remainder of such payments
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code) as soon as the amount thereof can be determined but in no event later than
the thirtieth day after the Date of Termination. In the event that the amount of
the estimated payments exceeds the amount subsequently determined to have been
due, such excess shall constitute a loan by the Company to you, payable on the
fifth day after demand by the Company (together with interest at the rate 
provided in Section 1274(b)(2)(B) of the Code).

               (f) Except as provided in the second sentence of Subsection
5(c)(iii) hereof, you shall not be required to mitigate the amount of any
payment provided for in this Section 5 by seeking other employment or otherwise,
nor shall the amount of any payment or benefit provided for in this Section 5 be
reduced by any compensation earned by you as a result of employment by another
employer, by retirement benefits or by offset against any amount claimed to be
owed by you to the Company or otherwise.

           6.        Successors; Binding Agreement.

               (a) The Company will require any successor (whether direct or
indirect, by 


837921.1
                                      -10-

purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company expressly to assume
and agree to perform this Agreement to the same extent that the Company would be
required to perform it if no such succession had taken place. Failure of the
Company to obtain an assumption of this Agreement at or prior to the
effectiveness of any succession shall be a breach of this Agreement and shall
constitute Good Reason if you elect to terminate your employment, except that
for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Date of Termination. As used in
this Agreement, Company shall mean the Company as defined above and any
successor to its business or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

               (b) This Agreement shall inure to the benefit of and be
enforceable by your personal or legal representatives, executors,
administrators, successors, heirs, distributees,
devisees and legatees. If you should die while any amount would still be payable
to you hereunder if you had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to your devisee, legatee or other designee or if there is no such
designee, to your estate.

           7. Notice. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
duly given when delivered or when mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the
Chairman of the Board of Directors of the Company, at 111 Locke Drive,
Marlborough, Massachusetts 01752, and to you at the address shown above or to
such other address as either the Company or you may have furnished to the other
in writing in accordance herewith, except that notice of change of address shall
be effective only upon receipt.

           8.        Miscellaneous.

               (a) The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

               (b) The validity, interpretation, construction and performance of
this Agreement shall be governed by the laws of the Commonwealth of
Massachusetts.

               (c) No waiver by you at any time of any breach of, or compliance
with, any provision of this Agreement to be performed by the Company shall be
deemed a waiver of that or any other provision at any subsequent time.

               (d) This Agreement may be executed in counterparts, each of which
shall be deemed to be an original but both of which together will constitute one
and the same instrument.

               (e) Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law.

               (f) This Agreement sets forth the entire agreement of the parties
hereto in respect of the subject matter contained herein and supersedes all
prior agreements, promises, covenants, arrangements, communications,
representations or warranties, whether oral or written, by any officer, employee
or representative of any party hereto; and any prior agreement of the parties
hereto in respect of the subject matter contained herein is hereby terminated
and cancelled.

         If this letter sets forth our agreement on the subject matter hereof,
kindly sign and return to the Company the enclosed copy of this letter, which
will then constitute our agreement on this subject. 

Sincerely,

HEMASURE INC.
