5.  2001 RESTRUCTURING PROGRAM AND OTHER CHARGES:

    In the first quarter of 2001, in connection with the previously announced
    separation of the Company into two independent companies, a restructuring
    program was initiated to reorganize both the Microelectronics and BioScience
    businesses of the Company. There were also costs associated with resizing
    the Microelectronics business in view of the current microelectronics
    industry downturn. The program included reducing, consolidating and
    outsourcing of certain manufacturing operations, centralization of European
    shared services (including order processing, cash collections and cash
    applications processes) and streamlining certain corporate shared services
    and divisional overhead functions to serve smaller organizations.

                   (Dollars in millions, shares in thousands)

    These initiatives included a $28.1 million restructuring charge and $2.4
    million of fixed asset write-offs for assets that are no longer in use. The
    restructuring charge included $26.7 million of employee severance costs and
    $1.4 million of lease cancellation costs. The severance costs included non-
    cash stock based compensation expense related to changes in stock awards.
    Approximately 420 positions will be eliminated and the affected employees
    were notified by March 31, 2001, however a number of these employees will
    continue in their existing positions with their related salary costs charged
    to operations as incurred. Under the terms of the severance agreements, the
    Company expects to pay severance and associated benefits through 2002.
    Through March 31, 2001, approximately 100 employees have left the Company
    and $2.8 million of cash severance benefits have been paid.

    balances at March 31, 2001:

    In the first quarter of 2001, the Company also incurred professional fees of
    approximately $3.5 million related to the separation of the Company's
    Microelectronics and BioScience business segments.

6.  BUSINESS SEGMENT INFORMATION: The Company has two reportable business
    segments: BioScience and Microelectronics. The results for BioScience,
    Microelectronics and Corporate are presented below in "local currencies".
    Local currency results represent the foreign currency balances translated,
    in all periods presented, at Millipore's budgeted exchange rates for 2001,
    thus excluding the impact of fluctuations in the actual foreign currency
    rates. The Company's management uses this presentation for internal
    evaluation of the financial performance of the Company's business segments
    because it believes that the local currency results provides a clearer
    presentation of underlying business trends. The U.S. dollar results
    represent the foreign currency balances translated at actual exchange rates.

9.  ADOPTION OF NEW ACCOUNTING PRONOUNCEMENT:

    Effective January 1, 2001, the Company adopted SFAS No. 133, "Accounting for
    Derivative Instruments and Hedging Activities," as amended by SFAS No. 138.
    SFAS No. 133 establishes accounting and reporting standards requiring that
    every derivative instrument, including certain derivative instruments
    embedded in other contracts, be recorded in the balance sheet as either an
    asset or liability measured at its fair value. The statement also requires
    that changes in the derivative's fair value be recognized in earnings unless
    specific hedge accounting criteria are met.

    With respect to all derivative instruments, SFAS No. 133 requires that
    companies, upon adoption of the new standard, record an adjustment to record
    the difference between a derivative's previous carrying amount and its
    current fair market value as a transition adjustment. At December 31, 2000,
    the Company was a party to U.S. dollar to Japanese yen foreign currency
    fixed rate-to-fixed rate interest rate swap agreements, which were
    designated as a hedge of the Company's net investment exposure in its
    Japanese subsidiary. On January 1, 2001, the Company recorded a net
    derivative liability transition adjustment of $5.1 million which was the
    difference between the Company's carrying value and the fair value of this
    derivative. This transition adjustment was recorded as a cumulative-effect
    type adjustment to other comprehensive income. During the first quarter of
    2001, the swap agreements were terminated and a gain of $0.8 million was
    realized and recorded in other comprehensive income. In addition, the
    Company is no longer required to provide any cash collateralization which
    had previously been required as part of one its swap agreements.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Local Currency Results
- ----------------------
The following discussion of the Results of Operations includes reference to
revenue, margins and expenses in "local currencies". Local currency results
represent the foreign currency balances translated, in all periods presented, at
Millipore's budgeted exchange rates for 2001, thus excluding the impact of
fluctuations in the actual foreign currency rates.  The Company's management
uses this presentation for internal evaluation of the financial performance of
the Company's business segments because it believes that the local currency
results provide a clearer presentation of underlying business trends.  The U.S.
dollar results represent the foreign currency balances translated at actual
exchange rates.

Results of Operations
- ---------------------
Consolidated net sales for the first quarter of 2001 were $245 million, an
increase of 9% over sales for the same period last year.  The Company reported
earnings per share of $0.11 for the first quarter of 2001 compared to earnings
per share of $0.56 for the first quarter of 2000. Excluding restructuring
charges and other costs incurred to separate the Microelectronics business in
the first quarter of 2001, earnings per share were $0.59.

The following table summarizes sales growth by business segment and geography in
the first quarter of 2001 as compared to the first quarter of 2000 (U.S. dollars
in millions):

Currency Translation
- --------------------

Currency translation reduced reported sales growth rates by 5 percentage points
in the first quarter of 2001 due to the weakening of the Euro, the British pound
and the Japanese yen. If foreign exchange rates remain at April 27, 2001 levels,
the expected second quarter and full year 2001 sales growth rates in dollars
will be lower than local currency growth rates.

Business Segment Results
- ------------------------

BioScience Segment:

BioScience sales, in local currency, increased 14% in the first quarter of 2001
compared to the first quarter of 2000. Double digit sales growth, in local
currency, was reported in all geographies. Sales growth was strongest to
customers in biotechnology markets and also to life science customers.

BioScience operating income, in local currency, increased 23% in the first
quarter of 2001 over the first quarter of 2000 as a result of the increased
sales combined with improved gross profit margins.  The improved gross profit
margin percentage was attributed to an increased mix of consumable product sales
that generally have higher margins.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Microelectronics Segment:

Microelectronics sales, in local currency, increased 14% in the first quarter of
2001 compared to the same period last year.  Sales growth was positive in all
geographies with the most significant growth in Europe and Asia/Pacific. First
quarter of 2001, sequential quarter sales growth was down 15% from the fourth
quarter of 2000. Although recently published industry results and forecasts
depict trends of continued decline in demand for both semiconductors and
semiconductor capital equipment for at least the remainder of 2001, the extent
and the duration of this industry downturn to the Microelectronics segment is
unknown.

Microelectronics operating income, in local currency, decreased from $16.8
million or 22% of sales in the first quarter of 2000 to $14.0 million or 16% of
sales in the first quarter of 2001.  The decrease is primarily due to reduced
gross profit margins offset by sales growth and operating expense leverage.  The
gross profit margins were negatively impacted by having more manufacturing
employees than needed based on the reduced demand. The Company responded during
the quarter by restructuring its manufacturing operations for the industry
downturn.

Corporate Expenses:

Corporate expenses, in local currency decreased from $14.0 million to $11.8
million in the first quarter of 2001 as compared to the same quarter of the
prior year.  The decreased expenses related primarily to reduced variable
compensation expense.

Restructuring and Other Charges
- -------------------------------
In the first quarter of 2001, in connection with the previously announced
separation of the Company into two independent companies, a restructuring
program was initiated to reorganize both the Microelectronics and BioScience
businesses and to prepare them to operate successfully as two independent
companies.  There were also costs associated with resizing the Microelectronics
business in view of the current microelectronics industry downturn.

Key initiatives which will be substantially concluded in the next twelve months
include:

    o  Globally streamlining certain corporate shared services and divisional
       overhead functions to serve smaller organizations
    o  Centralizing into two locations European shared services including order
       processing, cash collections and cash applications processes
    o  Closing the manufacturing operation in China in order to reduce
       manufacturing infrastructures
    o  Outsourcing certain manufacturing processes in Puerto Rico to third party
       vendors in order to create a more flexible cost structure
    o  Reducing and reorganizing Microelectronics manufacturing including
       reduction of manufacturing workforce due to the current industry downturn
       and reorganizing manufacturing to better leverage worldwide manufacturing
       capacity

These initiatives included a $28.1 million restructuring charge and $2.4 million
of fixed asset write-offs for assets which are no longer in use. The
restructuring charge included $26.7 million of employee severance costs and $1.4
million of lease cancellation costs. Approximately 420 positions will be
eliminated and the affected employees were notified by March 31, 2001, however
for employees temporarily continuing in their existing positions, related salary
costs will be charged to operations as incurred. Under the terms of the
severance agreements, the Company expects to pay severance and associated
benefits through 2002. Through March 31, 2001, approximately 100 employees have
left the Company and $2.8 million of severance benefits have been paid.

The restructuring program is expected to yield annualized savings of
approximately $20 million.  The savings will result in reduced wages, facility
related costs and depreciation.  The savings will be reflected in cost of sales,
selling, general and administrative expenses and research and development
expenses.  The savings will begin in the second quarter of 2001 but will not be
fully realizable until the second half of this year and into the first quarter
of 2002.

                                       9


                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

During the next several quarters, the Company expects to incur approximately $4
million of additional operating expenses associated with the restructuring
program.  These costs primarily relate to the closure of leased facilities and
fixed assets that are currently in use and employee retention bonuses.  In
addition, the Company plans to open a Microelectronics manufacturing plant in
Ireland in 2002 and will incur additional restructuring and operating expenses
to relocate production activities.

In the first quarter of fiscal 2001, the Company also incurred professional fees
of $3.5 million related to the separation of the Company's Microelectronics and
BioScience business segments.

Consolidated Results
- --------------------
Gross profit margins, in local currencies, were 53% in the first quarter of 2001
compared to 55% reported in the first quarter of 2000.  The margin reduction can
be primarily attributed to relatively higher manufacturing costs in the
Microelectronics segment.

Selling, general and administrative expenses (SG&A), in local currencies,
increased 4% in the first quarter of 2001 as compared to the first quarter of
2000. This increase is primarily attributed to additional headcounts and
increased spending due to higher sales volume.  As a percentage of net sales,
SG&A expenses in local currencies decreased approximately 2 percentage points.

Research and development (R&D) expenses, in local currencies, increased 14% in
the first quarter of 2001 as compared to the first quarter of 2000. This
increase is due to additional research and development programs.  As a
percentage of sales, R&D expenses remained constant at 6.5%.

Operating income, excluding restructuring and other costs, in the first quarter
of 2001 as compared to the same period of the prior year in U.S. dollars, was
adversely effected by the impact of the weakened Euro, British pound and
Japanese Yen. If current foreign exchange rates remain in effect for the second
quarter and full year of 2001 then foreign exchange will have a more significant
negative impact on operating income as compared to the same periods of the prior
year.

Net interest expense decreased in the first quarter of 2001 as compared to the
first quarter of 2000 primarily attributed to lower average borrowings.

The effective income tax rate, excluding unusual expenses for the 2001
restructuring program, for the first quarter of 2001 was 22.0% compared to 21.0%
for the first quarter of 2000.  The effective income tax rate on the
restructuring and other charges was 35% because these charges occurred in
countries with higher tax rates.

Change in Accounting for Derivative Financial Instruments
- ---------------------------------------------------------
Effective January 1, 2001, the Company adopted SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities," as amended by SFAS No. 138. SFAS
No. 133 establishes accounting and reporting standards requiring that every
derivative instrument, including certain derivative instruments embedded in
other contracts, be recorded in the balance sheet as either an asset or
liability measured at its fair value. The statement also requires that changes
in the derivative's fair value be recognized in earnings unless specific hedge
accounting criteria are met.

With respect to all derivative instruments, SFAS No. 133 requires that companies
record an adjustment to record the difference between a derivative's previous
carrying amount and its current fair market value as a transition adjustment. At
December 31, 2000, the Company was a party to U.S. dollar to Japanese yen
foreign currency fixed rate-to-fixed rate interest rate swap agreements, which
were designated as a hedge of the Company's net investment exposure in it's
Japanese subsidiary. The Company recorded a net derivative liability transition
adjustment of $5.1 million, on January 1, 2001, to record the difference between
the Company's carrying value and the fair value of this derivative. This
transition adjustment was recorded as a cumulative-effect type adjustment to
other comprehensive income.  During the first quarter of 2001, the swap
agreements were terminated and a gain of $0.8 million was realized and recorded
to other comprehensive income.  In addition, the Company is no longer required
to provide any cash collateralization which had previously been required as part
of one its swap agreements.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Foreign Exchange
- ----------------
A substantial portion of the Company's business is conducted outside of the
United States through its foreign subsidiaries.  This business is transacted
through the Company's network of international subsidiaries generally in the
local currency. Approximately 30% of the Company's sales are derived from Europe
where the U.S. dollar continued to strengthen against the Euro during the first
quarter of 2001.  The Company is able to partially mitigate the impact of
fluctuations in the Euro by active management of cross border currency flows and
material sourcing.  Additionally, the Company has significant exposure to
changes in the Japanese yen that can not be mitigated through normal financing
or operating activities.  Accordingly, the net equity exposure had been managed
through the use of debt swap agreements. The Company terminated the debt swap
agreements in the first quarter of 2001 and intends to pursue other instruments
in the second quarter of 2001 to mitigate the yen exposure. Generally, when the
U.S. dollar strengthens against currencies in which the Company transacts its
business, sales and net income will be adversely impacted.

Capital Resources and Liquidity
- -------------------------------
Cash used by operations in the first three months of 2001 was $4.8 million
compared to cash generated by operations of $7.5 million in the first three
months of 2000.  In the first quarter of 2001, net income of $5.2 million
(excluding the $30.5 million ($19.8 million after tax) of restructuring and
other expenses) was primarily offset by increases in inventories of $11.2
million and decreases in both accrued expenses of $16.3 million and accrued
income taxes of $18.1 million. The inventory growth related to both future sales
for the BioScience segment and purchase commitments for Microelectronics.  The
accrued expense decrease related to payments for employee compensation accrued
in 2000.  The Company also borrowed $17.5 million under its revolving credit
facility and received $8.2 million for stock option exercises and $3.2 million
of cash previously restricted as part of the close out of the debt swap
agreements.  Cash was used to invest $12.0 million in property, plant and
equipment and to pay dividends of $5.1 million.

Forward Looking Statements
- --------------------------
The foregoing Management's Discussion and Analysis of Financial Condition and
Results of Operations contain certain forward-looking statements based on
current management expectations involving substantial risks and uncertainties
that could cause actual results to differ materially from the results expressed
in, or implied by, these forward-looking statements.  These risks and
uncertainties include, without limitation, difficulties in the successful
implementation of our restructuring activities, as well as those risks and
uncertainties described in our Form 10-K for the year ended December 31, 2000.
