W.R. Grace & Co.-Conn.
Amicon Product Line
Combined Financial Statements
December 31, 1996


            Report of Independent Accountants


To the Board of Directors of
W.R. Grace & Co.-Conn.

In our opinion, the accompanying combined balance sheet
and the related combined statements of operations and of
cash flows present fairly, in all material respects, the
financial position of the Amicon Product line ("the
Business") of W.R. Grace & Co.-Conn. ("Grace") and
subsidiaries at December 31, 1996, and the results of its
operations and its cash flows for the year then ended in
conformity with generally accepted accounting principles.
These financial statements are the responsibility of the
management of W.R. Grace and the Business; our
responsibility is to express an opinion on these financial
statements based on our audit.  We conducted our audit of
these statements in accordance with generally accepted
auditing standards which require that we plan and perform
the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.
An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and
significant estimates made by management, and evaluating
the overall financial statement presentation.  We believe
that our audit provides a reasonable basis for the opinion
expressed above.

The Business was a separate product line of Grace and, as
disclosed in Note 1 to the accompanying financial
statements, has engaged in various transactions and
relationships with other Grace entities.  However, the
terms of these transactions may differ from those that
would result from transactions among unrelated parties.

1.  Summary of Significant Accounting Policies

The Business
Effective December 31, 1996, Millipore Corporation and its
subsidiaries  ("Millipore") purchased the Grace Amicon product
line (the "Business") of W.R. Grace & Co.-Conn. ("Grace") and
subsidiaries (the "Grace Group"), a wholly owned subsidiary of
W.R. Grace & Co. ("W.R. Grace"), by acquiring certain assets and
assuming certain liabilities of the Business worldwide from the
Grace Group as provided in the Amicon Worldwide Purchase and Sale
Agreement dated November 18, 1996, as amended December 31, 1996
(the "Agreement").

The Business develops, manufactures and distributes molecular
separation and purification products and systems to the life
science research, biotechnology and pharmaceutical industries in
both foreign and domestic markets.  The Business has
manufacturing facilities in Danvers, Massachusetts; Stonehouse,
England; Limerick, Ireland; and Lyon, France.  The Business also
maintains thirteen sales offices in Europe, the United States and
the Far East, of which seven offices are shared sales and
administrative facilities with the Grace Group.

Basis of Presentation
Under the terms of the Agreement, Millipore acquired from the
Grace Group (1) the capital stock of Prochrom S.A., a French
corporation; the capital stock of Amicon Limited, a United
Kingdom corporation; the capital stock of Amicon G.m.b.H., a
German corporation; and the capital stock of Amicon Canada
Limited, a Canadian corporation (collectively the
"Subsidiaries"); and (2) other worldwide operating assets and
liabilities of the Business in the following countries:

                    United States       Japan
                    Ireland             The Netherlands
                    France              Sweden
                    Italy               Switzerland

    These financial statements present the historical financial
    position, results of operations, and cash flows of the
    Business previously included in the W.R. Grace's
    consolidated financial statements.  The Securities and
    Exchange Commission, in Staff Accounting Bulletin Number 55,
    requires that historical financial statements of a
    subsidiary, division, or lesser business component of
    another entity include certain expenses incurred by the
    parent on its behalf.  Accordingly, included in the
    accompanying financial statements are costs allocated to the
    Business by the Grace Group (See Note 11).

    All transactions between the Business' locations included in
    these financial statements are referred to herein as
    "intracompany" transactions whereas transactions between the
    Business and the Grace Group are referred to herein as
    "intercompany" transactions.  Account balances of the
    Business with Grace or the Grace Group have been reported as
    part of parent company
    
    investment, except those related to the sale of product
    which have been included in intercompany accounts payable,
    as well as the payable from the German sales office to the
    Grace Group.

    Basis of Combination
    These combined statements have been prepared by combining
    the assets and liabilities of the Business.  All
    intracompany balances and intracompany profit relating to
    the Business have been eliminated in preparing the financial
    statements, except as noted above.

    Financial Instruments
    At December 31, 1996, the carrying value of financial
    instruments, such as trade accounts receivable, accounts
    payable and accrued liabilities, approximate fair value,
    based on the short term maturities of these instruments.  At
    December 31, 1996, the fair value of notes payable and long-
    term debt also approximated book value as such indebtedness
    is based on current interest rates.

    Cash and Cash Equivalents
    The Business considers all highly liquid investments
    purchased with an original maturity of three months or less
    to be cash equivalents.

    Accounts Receivable and Concentrations of Credit Risk
    Financial instruments which potentially expose the Business
    to concentrations of credit risk consist primarily of trade
    accounts receivable. Ongoing credit evaluations of
    customers' financial condition are performed, and collateral
    is not required.  The Business maintains allowances for
    potential credit losses and such losses, in the aggregate,
    have not exceeded management's expectations.

    Revenue Recognition
    The Business generally recognizes revenue upon shipment of
    product.  The Business offers limited duration warranties
    for certain of its products and, at the time of sale,
    provides liabilities for all estimated warranty costs.

    The Business also recognizes revenue utilizing the
    percentage of completion method for sales of  certain
    products which meet specific sales criteria.  Earned revenue
    is based on the percentage that incurred costs to date bear
    to total estimated costs after giving effect to the most
    recent estimates of total costs.  Revisions in total
    estimated costs and anticipated losses are charged to income
    when identified.

    Inventories
    Finished goods and work-in-process inventories are valued at
    the lower of full absorption cost or market.  Cost flow is
    based on the first-in, first-out (FIFO) method.  Raw
    materials are valued at the lower of FIFO cost or realizable
    value.

    Properties and Equipment
    Properties and equipment are stated at cost.  Major renewals
    and improvements that extend the lives of the respective
    assets are capitalized.  Maintenance, repairs and renewals
    that do not extend the lives of the respective assets are
    charged to income as incurred.  Fully depreciated assets are
    retained in properties and equipment and related accumulated
    depreciation accounts until they are removed from service.
    For financial reporting purposes, depreciation is computed
    using the straight-line method over the estimated useful
    lives of the assets.

    Intangible Assets
    Included in other noncurrent assets are intangible assets
    (primarily drawings, patents and trademarks) of $150, net of
    accumulated amortization of $2,213.  These intangible assets
    are being amortized on a straight-line basis over 1 to
    15 years.

    Demonstration Equipment
    Included in other noncurrent assets is demonstration
    equipment of $586, net of accumulated amortization of
    $1,131.  Demonstration equipment represents equipment which
    is used by sales employees to demonstrate product during
    sales presentations to potential customers.  Demonstration
    equipment is being amortized on a straight line basis over
    two years.  Gains and losses on sales of demonstration
    equipment is included in gross profit.

    Goodwill
    Goodwill represents the excess of the purchase price over
    the fair value of the net assets of businesses acquired,
    which is being amortized on a straight line basis over forty
    years.  Goodwill amounted to $20,377, net of accumulated
    amortization of $6,985.

    Impairment
    The Business has adopted statement of Financial Accounting
    Standards No. 121 ("SFAS 121"), "Accounting for the
    Impairment of Long-Lived Assets and for Long-Lived Assets to
    Be Disposed of."  In accordance with SFAS 121, the Business
    reviews long-lived assets and related goodwill for
    impairment whenever events or changes in circumstances
    indicate that the carrying amounts of such assets may not be
    fully recoverable.  The adoption of SFAS 121 did not have a
    material effect on the Business financial position or result
    of operations.

    Income Taxes
    Historically, the results of certain of the Business'
    operations have been included in either the consolidated
    income tax returns of W.R. Grace or the income tax returns
    of other members of the Grace Group.  As such, W.R. Grace or
    the Grace Group paid income taxes attributable to the
    Business; this has been reflected in parent company
    investment.  The income tax expense and other tax related
    information included in these financial statements have been
    calculated as if the operations of the Business were not
    eligible to be included in the consolidated tax returns of
    W.R. Grace or other members of the Grace Group but rather
    were stand-alone taxpayers.

    The provisions of Statement of Financial Accounting
    Standards No. 109 "Accounting for Income Taxes"
    ("SFAS 109"), have been retroactively applied to these
    financial statements.  SFAS 109 is an asset and liability
    approach that requires the recognition of deferred tax
    assets and liabilities for the expected future tax
    consequences of events that have been recognized in the
    financial statements or tax returns.  Deferred tax expense
    (benefit), represents the change in the net deferred tax
    asset or liability balance.  In estimating future tax
    consequences, SFAS 109 generally considers all expected
    future events other than anticipated changes in the tax law
    or rates.

    Foreign Currency Translation
    Results of foreign operations are translated using average
    exchange rates during the year, while assets and liabilities
    are translated using exchange rates in effect at year end.
    Exchange gains and losses resulting from foreign currency
    transactions denominated in currencies other than the
    respective functional currencies are recorded based on the
    difference in exchange rates from the date the transaction
    is initially recorded to the date it is settled, or the
    exchange rate in effect at December 31, 1996, if it was not
    settled.

    Sale of Investment in Separex S.A.
    During 1996, the Business sold its 12% equity interest in
    Separex S.A., a research and development company, for
    approximately $273.  The resulting gain on the transaction
    of $211 has been included in other income and expense in the
    combined statement of operations.

    Advertising Expense
    The Business records advertising expense when incurred.
    Advertising expense was $1,312 for the year and is included
    in selling expenses.

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

         Total borrowings                     $ 3,778


    In October 1996, the Business French subsidiary entered into
    a FF 35,000 ($6,700 at December 31, 1996) annual revolving
    credit facility agreement with a bank.  Advances on the
    revolving credit facility bear interest at the Paris
    Interbank rate plus .25% (3.44% at December 31, 1996).  Cash
    overdrafts funded by the revolving facility bear interest at
    4.33%.  The revolving credit facility is payable on demand
    and is guaranteed by Grace Group.

    The term loan represents amounts borrowed under a long-term

    U.S. and foreign taxes have not been provided on foreign
    undistributed earnings of  approximately $19,702, as such
    earnings are being retained indefinitely for reinvestment.
    The distribution of these earnings would result in
    additional foreign withholding taxes and additional U.S.
    federal income taxes to the extent they are not offset by
    foreign tax credits, but it is not practicable to estimate
    the total tax liability that would be incurred upon such a
    distribution.

    At December 31, 1996, the Business has foreign net operating
    loss carryforwards of $1,900 which expire in various amounts
    through the year 2002, and foreign net operating loss
    carryforwards of approximately $1,700 which do not expire.
    A full evaluation allowance has been provided on all foreign
    net operating losses and credit carryforwards.


9.   Pension Plans

    The Grace Group maintains defined benefit pension plans
    covering employees of certain units including the Business,
    who meet age and service requirements.  Benefits are
    generally based on final average salary and years of
    service.  The Grace Group funds its pension plans in
    accordance with statutory laws and regulations.  Plan assets
    are invested primarily in common stock and fixed income
    securities.

    For purposes of these financial statements, all employees,
    except those of the subsidiary in Germany, are considered to
    have participated in a multiemployer pension plan as defined
    in Statement of Financial Accounting Standards No. 87,
    "Employers Accounting for Pensions," ("SFAS 87").  For
    multiemployer plans, employers are required to recognize as
    net pension expense total contributions for the period.
    With respect to these plans, the Business recorded expense
    of $606 in 1996.  No contributions are due or unpaid at
    December 31, 1996.


10.  Parent Company Investment

    As the majority of the Business' operations are conducted as
    divisions of Grace Group, not as distinct legal entities,
    there are no customary equity and capital accounts.
    Instead, parent company investment (i.e., of the Grace
    Group) is maintained by the Business and the Grace Group to
    account for intercompany transactions and the net assets of
    the Business, as more fully described in Note 11.  No
    interest has been charged on the parent company investment.
    A summary of changes in parent company investment is as
    follows:

    Parent company investment at December 31, 1995 $  41,791
      Net income                                       2,734
      Net change in amount due to parent                 764


    Parent company investment at December 31, 1996 $  45,289



11.  Related Party Transactions

    Intercompany Purchases
    The Business purchases silica media from the Grace Group
    under agreed upon pricing structure agreements.

    Corporate and Divisional Services
    The Grace Group allocates or charges a portion of its
    domestic and foreign corporate expenses  to respective
    Business units.  These include Grace executive management
    and corporate overhead; postretirement benefit and pension
    costs; benefit administration; risk management/insurance
    administration; tax and treasury/cash management services;
    environmental services including costs of remediation;
    litigation administration services; and other support and
    executive functions.

    All of the allocations and charges described above, are
    included in general and administrative expenses in the
    combined statement of operations.  Such allocations and
    charges are based on either a direct cost pass through or a
    percentage of total costs for the services provided based on
    factors such as net sales, management time or headcount.
    Such allocations and charges totaled $711 for 1996.

    Domestically, the Business was charged, based on the
    Business' experience, for its share of workers'
    compensation, employee life, medical and dental, and other
    general business liability insurance premiums and claims
    handled on a corporate-wide basis.  These charges are based
    upon a combination of experience and payroll dollars and
    totaled $746 in 1996, and are included in either cost of
    goods sold, selling expenses or general and administrative
    expenses, depending upon the nature of the function.

    Domestic corporate research and development expenses and
    overheads directly related to the Business of $55 have been
    charged or allocated to the Business and are included in
    research and development expenses.

    Foreign
    Sales operations of the Business which are operated within
    wholly owned subsidiaries of Grace are allocated central
    administrative service costs from the Grace Group related to
    personnel, information systems, space and warehousing,
    employee benefits, general liability insurance, engineering,
    financial reporting, general management and other staff
    services.  In addition, the Business' European and
    Asia/Pacific operations were allocated or charged similar
    costs by the Grace Group's regional headquarters in
    Lausanne, Switzerland and Hong Kong.  Such amounts totaled
    $651, all of which is included in selling or general and
    administrative expenses.

    Management believes that the bases used for allocating
    corporate and divisional services and common sales
    facilities costs are reasonable.  However, the terms of
    these transactions may differ from those that would result
    from transactions among unrelated parties.
