Exhibit 10.6




                            MASTER PURCHASE CONTRACT


         This MASTER PURCHASE CONTRACT (the "Contract"), dated as of July 1,
1999, is by and between  HemaSure Inc., a Delaware  corporation  (the "Vendor"),
and The American National Red Cross, a not-for-profit  corporation  chartered by
an act of Congress (the "Purchaser").


                                    RECITALS

         WHEREAS the Vendor is the developer and manufacturer of the HemaSure
r\LS Prestorage Leukoreduction Filtration System (the "Filtration System") for
the reduction of leukocytes in red blood cells; and

         WHEREAS the Purchaser desires to purchase Filtration Systems for use in
its blood collection and filtration programs at various facilities of American
Red Cross Blood Services (each, a "Red Cross Center") located throughout the
United States.

         NOW, THEREFORE, in consideration of the mutual covenants and promises
contained herein, and for other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:



         1.   Term. The term of this Contract is three (3) years and two (2)
months, beginning July 1, 1999 and ending August 31, 2002, unless extended or
earlier terminated pursuant to Sections 2.2 or 12 below. The Contract consists
of a fourteen (14) month period (July 1, 1999 - August 31, 2000) and two (2)
consecutive twelve (12) month periods beginning on September 1, 2000 (each of
such three separate periods is herein referred to as a "year" of the Contract
Term, including the fourteen (14) month period).

         2.   Purchase and Sale Obligations.

              2.1   Pricing Levels. The Vendor agrees to sell Filtration Systems
to the Purchaser, and the Purchaser agrees to purchase such Filtration Systems
from the Vendor, at the confidential quantity and price levels set forth on
Schedule I hereto and incorporated herein.

              2.2   Minimum Purchase Requirement. In the first year of the
Contract Term, the Purchaser shall purchase from the Vendor and the Vendor must
provide not fewer than

850681.5
                                       -1-

<PAGE>



400,000 Filtration Systems. In the second year of the Contract Term, the
Purchaser shall purchase from the Vendor and the Vendor must provide not
fewer than 700,000 Filtration Systems. In the third year of the Contract Term,
the Purchaser shall purchase from the Vendor and the Vendor must provide not
fewer than 1,000,000 Filtration Systems. In the event that the Purchaser fails
to meet the minimum purchase requirement in any Contract Term year, the
remaining number of Filtration Systems necessary to meet such minimum purchase
requirement will be added on to the minimum purchase requirement of the
subsequent Contract Term year. In the event that the Purchaser fails to meet the
minimum purchase requirement in the third year of the Contract Term, the term of
this Contract shall be extended for one year during which time the Purchaser
must purchase the remaining number of Filtration Systems as are necessary to
meet the minimum purchase requirement of the previous year.

              2.3   Surcharge. In the event that the Purchaser fails to satisfy
the minimum purchase requirements set forth in Section 2.2 of the Contract for
any year of the Contract Term, the Purchaser must pay to the Vendor a surcharge
of $1.50 per Filtration System purchased. For example, if 350,000 Filtration
Systems were purchased for Contract Year 1, there would be an aggregate
surcharge of $525,000 (350,000 x $1.50). In that situation, the Purchaser is
then required to purchase a minimum of 750,000 Filtration Systems in Contract
Year 2 to avoid the application of a surcharge for that year. The same method of
surcharge calculation shall apply to any subsequent Contract years as well. The
surcharges set forth in this section 2.3 shall not apply if Vendor is unable to
provide such Filtration Systems or to force majeure events as set forth in
Section 16.1.

              2.4   Purchase Volume Credits.1 If, (i) as a direct result of the
Purchaser's efforts either the Australian Red Cross or the Japanese Red Cross
place orders for the purchase of Filtration Systems from the Vendor and (ii) on
or prior to June 30, 2000 the Japanese Red Cross or the Australian Red Cross, as
the case may be, executes and delivers to the Vendor a definitive, firm
commitment agreement to purchase Filtration Systems from the Vendor, and shall
in fact purchase such Filtration Systems, then, the volume of such purchases,
when and as made and paid for, will be added to the volume of the Purchaser's
purchases for the purpose of computing price level volumes for the Purchaser
hereunder.

              2.5   Purchaser Affiliates. The price levels available to the
Purchaser under this Contract will be made available to domestic affiliates of
the Purchaser pursuant to written purchase contracts with the Vendor containing
terms satisfactory to the Vendor. The Purchaser will provide the Vendor with a
list of such domestic affiliates of the Purchaser on a semi-annual basis,
together with documentation reasonably satisfactory to the Vendor evidencing
such domestic affiliate status.

              2.6   Price Level Adjustments. If as a result of any technological
development or manufacturing process improvements in respect of manufacturing
technologies, filtration media or other significant aspects of the manufacturer
or production of the Filtration System the Vendor achieves and realizes a
substantial reduction in the Vendor's current estimated volume cost of
production and manufacture of such Filtration Systems as of the date hereof, the
Vendor will discuss with the Purchaser, and effect, a fair and reasonable
downward adjustment in the price level set forth in Section 2.1 above; provided,
however, the Vendor shall only be required to effect such a downward price
adjustment under the circumstances detailed in the previous sentence and not in
respect of any production or manufacturing cost or expense savings associated
with increased volume production, economies of scale, or otherwise.

        3.    Purchase Orders.

              3.1   Form of Purchase Orders. Purchase orders for Filtration
Systems shall be submitted to the Vendor in writing, via facsimile, or via
telephone with a confirmation in writing, and shall specify the desired quantity
of Filtration Systems, delivery date and delivery location. The Vendor shall
designate persons within its customer services department who will be
responsible for receiving telephone orders from the Purchaser's representatives.
Telephone orders must be placed between 8:30 a.m. and 5:30 p.m. Eastern Time.
The Vendor may institute a new procedure for placing orders, including a system
through which purchase orders are electronically generated; provided, however,
that such new ordering procedure does not result in additional costs to the
Purchaser.

              3.2   Authorized Purchasing Representatives. Unless the Purchaser
notifies the Vendor in writing, purchase orders shall be placed separately with
the Vendor for each Red Cross Center by the Purchasing Office located at the
Blood Services Area Office in Dedham, MA, Charlotte, NC, Detroit, MI, St. Louis,
MO or Phoenix, AZ. Each Area Office shall provide to the Vendor a list of
personnel who are authorized to place purchase orders with the Vendor. The
Vendor shall accept purchase orders only from such authorized personnel.

        4.    Payment.

              4.1  Accepted Goods. Payment is due for all goods accepted as set
forth in Section 5.3 below.

              4.2  Time of Payment. Separate invoices will be sent by the Vendor
to each Blood Services Area Office that placed an order with the Vendor. Payment
is due to the Vendor within thirty (30) days of the date of the invoice, such
invoices to be dated and mailed no earlier than the day of product shipment to
the Red Cross Center. The Vendor shall assess service and/or interest charges of
up to 1% per month on any past due amounts.

of the Vendor's facility to determine the Vendor's material compliance with Part
820 of the Code of Federal Regulations 21 (Quality System Regulations) and (ii)
conduct a review and audit of the Vendor's computer and accounting systems to
determine material compliance with reasonable "Year 2000" compliance standards
to be mutually agreeable to the Vendor and the Purchaser. The Vendor covenants
and agrees with the Purchaser to use commercially reasonable efforts to remedy
any material deficiencies discovered by the Purchaser during the foregoing
audits, and any failure by the Purchaser to do so shall constitute a Termination
for Breach pursuant to Section 12.1 below (subject to the cure periods set forth
therein); provided, however, that with respect to clause (ii) of the preceding
sentence, the Vendor shall not be deemed to have breached this Agreement unless
the discovered non-compliance (and subsequent failure to cure) has a material
adverse effect on the operations of the Purchaser or on the ability of the
Vendor to fulfill its obligations under this Agreement.

              All records, files, reports, manuals, studies, photographs,
negatives, source code (including hard copies of all programs), calibration and
performance records, development and validation records, change control

<PAGE>



made available to the Purchaser or to persons and or entities to which the
Purchaser is required by law, regulation or otherwise to grant access to such
documents, immediately upon request at any time during performance under
this Contract and for a period of five (5) years after final payment for all
deliverables and services provided by the Vendor. If a longer retention time is
required by law or regulatory agency, the Purchaser will notify the Vendor prior
to the end of the Contract.

              It is further agreed that the Vendor will provide immediate access
to the Purchaser or its representatives and the FDA to all documents relating to
the performance of the deliverables and services under this Contract. The Vendor
will allow prompt access during normal business hours to the Purchaser, and
immediate access to the FDA, to all such documents and to its facilities where
work is performed under this Contract or support is provided in connection with
the deliverables or services provided under this Contract at any time (with
reasonable advance notice in the case of the Purchaser's access) for purposes of
FDA inspections or other requests for access by the FDA.

              11.4  Adequate Supply. At least thirty (30) days before the end of
each calendar quarter, the Purchaser will prepare and furnish to the Vendor an
annual forecast, by month, for the following four calendar quarters, specifying
the proposed quantity of r\L S Filtration Systems which will be purchased for
delivery during each month of that year. The Vendor hereby guarantees that it
will be able to provide, at a minimum, the quantities of Filtration Systems
reflected in the minimum purchase requirements for each of the Contract years
(Section 2.2). The Vendor shall undertake reasonable efforts to ensure that all
the Purchaser's additional quantity needs for Filtration Systems are met by the
Vendor.

              11.5  Customer, Technical Service and Training. The Vendor shall
designate one employee who shall have primary responsibility for servicing this
Contract and the Vendor shall make this employee reasonably available during
normal business hours to discuss Contract issues with the Purchaser. The Vendor
shall maintain a Technical Services Department for the purpose of providing

on-site, hands-on training program at each participating American Red Cross
Regional Center. American Red Cross Centers and their personnel may direct
technical questions to the Vendor using a toll-free number, to be provided by
the Vendor, or such American Red Cross Center may contact the Vendor's Technical
Services trainers directly via telephone or pager. The Vendor's Technical
Services Trainers shall also be available to the Purchaser to provide seminars
on an area basis or to attend any regional meetings where their presence and
input will be of value to the American Red Cross.

        12.       Termination.

              12.1  For Breach. The Purchaser may terminate this Agreement,
without any liability except to pay for accepted filters, on thirty (30) days
prior written notice if the Vendor

850681.5
                                       -8-

<PAGE>



is in material breach of this Agreement and has not cured such breach within
thirty (30) days of written notice of such breach. The Vendor may terminate this
Agreement on thirty (30) days prior written notice, if the Purchaser is in
material breach of this Agreement and has not cured such breach within thirty
(30) days of written notice of such breach.

              12.2  FDA. In the event that the FDA revokes approval of the

              12.3  Technological Change. If (i) as a result of a technological
change, new products become available which provide substantial improvements in
the safety of blood services or the efficiency of blood collection, through
automated collection or filtration strategies or viral inactivation systems or
other methods currently unknown and (ii) it can be shown by mutually agreed upon
independent experts in the blood collection field that any such new product
described in the preceding clause provides a substantial and meaningful clinical
benefit or substantial and material economic advantage compared to the
Filtration System, then the Purchaser, upon delivery to the Vendor of the
results of such independent experts' analysis and thirty (30) days prior written
notice, may terminate this Contract without any liability except to pay for
accepted filters.

              12.4 For Change in Circumstances. The Purchaser may terminate this
Contract with ninety (90) days prior written notice at any time prior to the
completion of the Contract if the Purchaser has no further requirement for the
use of leukoreduction filters generally. In the event of such termination, the
Vendor agrees to cease immediately all work for the Purchaser and the liability
of the Purchaser shall be limited to payment for filters already delivered.

              12.5  For Change in Policy or Mandate. The Purchaser may terminate
this Contract by thirty (30) days prior written notice at any time prior to
completion of the Contract if (i) there has occurred any material change in the
policies or mandates of the American National Red Cross that make such
termination necessary or desirable and (ii) the Purchaser has purchased from the
Vendor, and has paid for, not fewer than 2.1 million Filtration Systems
hereunder. In the event of such a termination, the Purchaser promptly shall pay

<PAGE>



liability, claim, cost or expense (including reasonable attorneys' fees) with
respect to bodily injury, death, and property damage arising from the
willful misconduct or negligent activity of the Vendor, its directors, officers,
employees or agents during its performance of its responsibilities under this
Contract, including but not limited to any claim against the Purchaser for
infringement of patent rights owned or held by competitors of the Vendor. The
Vendor further agrees to indemnify the Purchaser, its governors, directors,
officers, employees, volunteers and agents from and against any loss, damages,
costs, or expenses ("liability") in connection with any claim arising from any
defect in the Filtration Systems, or in the provision of any services pursuant
to this Contract, or by reason of the nature of the materials contained in said
Filtration Systems or provision of service, except to the extent that the final
order of a court of competent jurisdiction has determined that a proportion of
such liability thereof was caused either by an alteration in, tampering with, or
non-intended usage of the Filtration Systems by the Purchaser or by the willful
misconduct or negligent activity of the Purchaser, its directors, officers or
employees, in which case, the Purchaser shall be responsible solely for its
proportionate share of the liability.

              13.2  Defense Obligations. In the event that the Vendor or the
Purchaser is, or both are, the subject of a third party claim, action, or
proceeding alleging injury or damages as a result of any manufacturing defect in
the Filtration System or in the provision of services pursuant to this Contract,
or for infringement of a patent held by a competitor of the Vendor, each party
shall provide the other with prompt notice thereof. The Vendor shall defend or
provide for the defense of such claim, action or proceeding at its sole costs
and expense. The Purchaser shall execute such documents and instruments deemed
necessary by the Vendor or its counsel and not in conflict or derogation of the
Purchaser rights under this Agreement. The Purchaser shall take such other
reasonable action the Vendor may request to assist the Vendor in its efforts on
such matters, including the provision of reasonable testimony or trial
assistance. The Purchaser shall not interfere with or take any steps to settle
such action. The Vendor shall reimburse the Purchaser for its documented and
reasonable out-of-pocket expenses in connection with providing any assistance
under this Section.

        14.  Insurance.  The Vendor shall  maintain the  following  insurance
coverages in full force and effect for the Term of this Contract.

                (i)   1) Commercial General Liability Insurance in an amount of
             at least $10,000,000 (Ten Million Dollars) naming the Purchaser an
             additional insured party; 2) an auto liability policy with at least
             $1,000,000 (One Million Dollars) in coverage; and 3) Workers'
             Compensation coverage covering each party's own employees with
             statutory limits for each jurisdiction where the work required
             under this Contract is performed (including monopolistic states if
