7.  Legal proceedings: On July 21, 1999 Amersham Pharmacia Biotech AB ("APB")
    (now known as Amersham Biosciences AB) of Sweden filed a complaint in the
    High Court of Justice in the United Kingdom against the Company and two of
    its subsidiaries alleging that the sale of the Company's ISOPAK
    chromatography valve infringed one or more of the claims contained in
    certain APB patents. APB sought an injunction against the alleged
    infringement as well as damages. On October 26, 2000, the High Court ruled
    that the chromatography valve currently sold by the Company did not infringe
    the APB patents. APB appealed this decision and, on July 5, 2001, the
    British Appeals Court affirmed the decision of the High Court. On February
    13, 2002, the House of Lords rejected APB's request for leave to appeal the
    decision of the Appeals Court. The High Court also ruled that a discontinued
    product did infringe one of the APB patents. A hearing on damages has yet to
    be scheduled with respect to this matter. In any event, the outcome of this
    suit is not expected to have a material adverse effect on the Company's
    financial position, cash flows and results of operations.

8.  Business Segment Information: The Company's chief decision makers evaluate
    the performance of the Company and make resource allocation decisions based
    on total consolidated company results. As a result of this evaluation, the
    Company determined that it has three operating segments: BioPharmaceutical,
    Laboratory Water and Life Sciences.

    BioPharmaceutical develops, manufactures and sells consumable products and
    capital equipment and provides related services used in drug manufacturing.
    Laboratory Water and Life Sciences manufacture and sell instrumentation,
    consumable products and services used in drug discovery and development.
    For all three of these operating segments within the bioscience industry,
    economic characteristics, production processes, products and services,
    types and classes of customers, methods of distribution and regulatory
    environments are similar. Because of these similarities, the three segments
    have been aggregated into one reporting segment for financial statement
    purposes.

     Please refer to the condensed consolidated financial statements for
     financial information regarding the one reportable segment of the Company.

 9.  Discontinued Operations: On February 27, 2002, the Company distributed its
     remaining ownership interest in Mykrolis Corporation common stock as a
     dividend to the Company's shareholders. At that date, the net assets of
     discontinued operations less minority interest was recorded as a $300.2
     reduction to shareholders' equity.

     In the first quarter of 2002, the $24.4 (net of tax) estimated loss on
     disposal of discontinued operations recorded in 2001 was reduced by $2.9
     (net of tax) to reflect the actual operating losses through the
     distribution date.

     In the second quarter of 2001, the Company and Mykrolis Corporation entered
     into various agreements covering a range of issues relating to the
     separation of Mykrolis Corporation from the Company. Among other things,
     these agreements provide for facilities, services, contract manufacturing
     and research for various periods of time and under various pricing
     arrangements. For the period from January 1, 2002 through February 27,
     2002, the Company recognized revenues of $0.5 and expenses were reduced by
     $1.3 as a result of these agreements.

     As discussed in note 10, the Company adopted SFAS No. 142 effective January
     1, 2002. The adoption of SFAS No. 142 did not have a significant impact on
     the Company's discontinued operations included in the consolidated
     financial statements. The aggregate amortization expense included in the
     accrued loss on disposal of discontinued operations was $0.4 in the second
     quarter of 2001 which would not have changed the basic or diluted income
     (loss) per share.

10.  Adoption of New Accounting Pronouncements: Effective January 1, 2002, the
     Company adopted SFAS No. 142, "Goodwill and Other Intangible Assets". SFAS
     No. 142 requires that ratable amortization of goodwill be replaced with
     periodic tests of the goodwill's impairment and that intangible assets
     other than goodwill be amortized over their economic lives. The adoption of
     SFAS No. 142 did not have an impact on the Company's continuing operations
     presented in the consolidated financial statements. SFAS No. 142 did not
     have a significant impact on the Company's discontinued operations. See
     note 9 for additional information regarding the impact of the adoption on
     the Company's discontinued operations.

     The following is the summary of amortized intangible assets:

Aggregate amortization expense for intangible assets for the six months ended
June 30, 2002 and 2001 was approximately $1.8 and $2.0, respectively.

The estimated aggregate amortization expense for amortized intangible assets
owned as of June 30, 2002 for each of the five succeeding fiscal years is as
follows:

            2002                          $    3.3
            2003                          $    2.9
            2004                          $    2.8

      Effective January 1, 2002, the Company adopted SFAS No.144, "Accounting
      for the Impairment or Disposal of Long-Lived Assets". SFAS No. 144
      supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived
      Assets and for Long-Lived Assets to be Disposed Of" and provides a single
      accounting model for long-lived assets to be disposed of. In addition, the
      standard eliminates the requirement to accrue for losses through the
      estimated date of disposal of a business. The adoption of SFAS No. 144 did
      not have an impact on the Company's consolidated financial statements.

                      MANAGEMENT DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Basis of Presentation

The following discussion of the Results of Operations includes reference to
"local currencies". Local currency results represent the foreign currency
balances translated, in all periods presented, at Millipore's budgeted exchange
rates for 2002, 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 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

of 2002 as compared to the second quarter of 2001:

</TABLE>

Net sales for the second quarter of 2002 were $176.1 million as compared to
$168.0 million for the same period of the prior year, an increase of 5 percent.
Sales growth of 4 percent, in local currency, was 100 basis points lower than
the 5 percent sales growth in U.S. dollars due to the impact of translating
sales denominated in currencies other than the U.S. dollar. In general, a weaker
U.S. dollar will positively impact sales growth. During the second quarter of
2002 as compared to the second quarter of 2001 the U.S. dollar weakened against
the Euro on average by approximately 4% and strengthened against the Yen by
approximately 4%. The geographic sales volume and the timing of sales
transactions during the quarter resulted in a more significant foreign exchange
impact to reported results from the Euro as compared to the Japanese Yen.

By geography, local currency sales in North America were flat with the same
quarter in 2001. Sales in the second quarter of 2001 were unusually strong in
the biopharmaceutical manufacturing business in the United States as a result of
sales to three customers which were completing and validating new manufacturing
facilities. The strong European sales growth, in local currency, in the second
quarter of 2002 was reflective of an expanding biotechnology business with both
U.S. multinational customers and European customers as well as strong sales of
instrumentation and consumables to laboratories. The Asia/Pacific business
declined 2% in local currency compared to the same quarter last year. We believe
this is primarily a result of the recessionary economic conditions in the
region, particularly in Japan.

By market, local currency revenue growth was strongest for products used in the
biotechnology markets (12%) and life science research (6%) which together
account for 49% of sales. The other bioscience markets which include classical
pharmaceutical, clinical and analytical laboratories and food and beverage
markets declined 2% in local currency. The strong growth in the biotechnology
markets is a combination of a 14% increase in consumables and a 2% increase in
hardware sales reflecting the continued growth of commercialized biologicals,
recombinant proteins and vaccines. The life science research growth rate has
declined as compared to the growth rates reported in the last few quarters
reflecting a decrease in demand as pharmaceutical companies shift resources from
discovery of new targets to validation of targets identified in 2000 and 2001.
We continued to see a decline in sales to ultra-high throughput sequencing
laboratories as these customers completed the study of their chosen model
organisms. Additionally, we believe recent customer consolidations have resulted
in a temporary reduction in demand as the consolidated companies refocus
projects, potentially relocate laboratories and work down duplicate inventories.
The declining demand in the other biosciences markets was primarily a result of
beverage customers' process improvements which enable a delay in consumable
change outs as well as a changing mix of products which require less
clarification. Additionally, the Company saw relatively flat demand for
sterilizing filtration devices used in feed

streams for parenteral products, vaccines and contact lens solutions. Offsetting
these was an approximately 1% growth in the laboratory general filtration
business.

Gross profit margins were 57.5% in the second quarter of 2002 compared to 57.1%
reported in the second quarter of 2001. The improved margins were the result of
a favorable mix of sales in high margin consumables, increased sales in higher
margin geographies and volume efficiencies. Somewhat offsetting this
favorability were increased costs resulting from the strengthening of the Euro
specifically for products manufactured in Europe which were sold to customers
located in other geographic locations.

Selling, general and administrative (SG&A) expenses increased 4% in the second
quarter of 2002 as compared to the second quarter of 2001. This growth rate is
consistent with the growth in sales. As a percentage of net sales, SG&A expenses
in local currencies were 31% in the second quarters of both 2002 and 2001.

Research and development (R&D) expenses increased 21% in the second quarter of
2002, as compared to the second quarter of 2001. This increase is due to planned
investments in strategic R&D programs particularly in biopharmaceutical
manufacturing applications. As a percentage of sales, R&D expenses represented
7.7% as compared to 6.7% in the same quarter of 2001.

In the first quarter of 2001, the Company initiated a restructuring program and
recorded a $16.5 million restructuring charge, consisting primarily of employee
termination costs and $1.5 million of fixed asset write-offs for assets which
were no longer in use. Approximately 215 positions were eliminated and, through
June 30, 2002, approximately 175 employees have left the Company. The $3.6
million remaining balance of the restructuring reserve at June 30, 2002 relates
primarily to employee severance costs which will be substantially paid by the
end of 2002.

Net interest expense decreased in the second quarter of 2002 as compared to the
second quarter of 2001 primarily attributed to lower average borrowings and
decreased average rates which were partially offset by lower interest income
from cash and cash equivalents. The decrease in average rates primarily relates
to the Company replacing its $100.0 million 7.23% unsecured note with available
borrowing capacity under its revolving credit facility which had a 3.1% average
rate during the second quarter of 2002.

The effective income tax rate for the second quarter of 2002 was 22% consistent
with the same quarter of the prior year.

Discontinued Operations

On February 27, 2002, the Company distributed its remaining ownership interest
in Mykrolis Corporation common stock as a dividend to Millipore shareholders. At
that date, the net assets of discontinued operations less minority interest was
recorded as a $300.2 million reduction to shareholders' equity.

In the first quarter of 2002, the $24.4 million estimated loss on disposal of
discontinued operations (net of tax) recorded in 2001 was reduced by $2.9
million (net of tax) to reflect the actual operating losses through the
distribution date.

In the second quarter of 2001, the Company and Mykrolis Corporation entered into
various agreements covering a range of issues relating to the separation of
Mykrolis Corporation from the Company. Among other things, these agreements
provide for facilities, services, contract manufacturing and research for
various periods of time and under various pricing arrangements. For the period
from January 1, 2002 through February 27, 2002, the Company recognized revenues
of $0.5 million and expenses were reduced by $1.3 million as a result of these
agreements.

Foreign Currency Exchange Rate Risks

A substantial portion of the Company's business is conducted outside of the
United States through its foreign subsidiaries, generally in the local currency.
Approximately 37% of the Company's sales are derived from Europe

where, in the second quarter of 2002 the U.S. dollar weakened against the Euro
and 19% of the sales are from Asia/Pacific where the U.S. dollar strengthened
against the Japanese Yen as compared to the second quarter of 2001. The Company
is able to partially mitigate the impact of currency fluctuations by active
management of cross border currency flows, varied geographic material sourcing
and the use of forward contracts to hedge certain foreign currency exposures.
Generally, when the U.S. dollar strengthens against currencies in which the
Company transacts its business, sales and net income will be adversely impacted.

The Company enters into forward foreign exchange contracts principally to hedge
the impact of currency fluctuations on certain intercompany balances. Principal
hedged currencies include the Euro, Japanese Yen and British Pound. The periods
of these forward contracts typically range for less than three months. At June
30, 2002, the Company held forward foreign exchange contracts with notional
amounts totaling approximately $25 million. The fair value of these contracts
was not material at June 30, 2002.

Capital Resources and Liquidity

Cash generated by operations in the first six months of 2002 was $22.4 million,
compared to $8.6 million in the first six months of 2001. The increase in cash
flow from operations was primarily the result of improvements in the collections
of accounts receivable in 2002 as compared to 2001 as well as the payment of
income taxes in first quarter of 2001 which was principally offset by increased
inventory in 2002. In both years, accrued expenses declined as prior year
incentive accruals were paid to employees. For the six months of 2002, although
accounts receivable increased $1.1 million, days sales outstanding in local
currencies improved from 85 days at December 31, 2001 to 83 days at the end of
the second quarter of 2002 related to improved collection activity primarily in
the United States which offset a mix of slower paying European and Japanese
customers. Inventory levels increased $13.7 million (10 days of supply in local
currency) due to anticipation of increased sales in the second half of 2002 and
specific raw material advance purchases. Cash generated by operations in 2001
was negatively impacted by approximately $20.0 million for payments made to
foreign tax jurisdictions.

Operating cash flow generated in 2002 was used to invest in $31.9 million of
property plant and equipment, other assets and intangibles. The Company also
paid $5.3 million of dividends in the first quarter of 2002. The Company
discontinued future dividend payments and instead will focus on investing in R&D
and building productive capacity. The Company received $12.6 million from the
exercise of employee stock options and increased borrowings under its revolving
credit facility by $18.8 million.

On April 1, 2002, the Company used available borrowing capacity under its
revolving credit facility to satisfy the $100.0 million 7.23% unsecured note due
at that time. Because of the Company's ability and intent to continuously
refinance such borrowings under its revolving credit facility, short-term
borrowings with maturities within the next 12 months have been classified as
long-term.

Legal Proceedings

On July 21, 1999 Amersham Pharmacia Biotech AB ("APB") (now known as Amersham
Biosciences AB) of Sweden filed a complaint in the High Court of Justice in the
United Kingdom against the Company and two of its subsidiaries alleging that the
sale of the Company's ISOPAK chromatography valve infringed one or more of the
claims contained in certain APB patents. APB sought an injunction against the
alleged infringement as well as damages. On October 26, 2000, the High Court
ruled that the chromatography valve currently sold by the Company did not
infringe the APB patents. APB appealed this decision and, on July 5, 2001, the
British Appeals Court affirmed the decision of the High Court. On February 13,
2002, the House of Lords rejected APB's request for leave to appeal the decision
of the Appeals Court. The High Court also ruled that a discontinued product did
infringe one of the APB patents. A hearing on damages has yet to be scheduled
with respect to this matter. In any event, the outcome of this suit is not
expected to have a material adverse effect on the Company's financial position,
cash flows and results of operations.

Adoption of New Accounting Pronouncements

Effective January 1, 2002, the Company adopted SFAS No.142, "Goodwill and Other
Intangible Assets" and SFAS No.144, "Accounting for the Impairment or Disposal
of Long-Lived Assets". SFAS No. 142 requires that ratable amortization of
goodwill is replaced with periodic tests of the goodwill's impairment and that
intangible

assets other than goodwill be amortized over their economic lives. The adoption
of SFAS No. 142 did not have a significant impact on the Company's consolidated
financial statements.

SFAS No. 144 supersedes SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and provides a
single accounting model for long-lived assets to be disposed of. In addition,
the standard eliminates the requirement to accrue for losses through the
estimated date of disposal of a business. The adoption of SFAS No. 144 did not
have an impact on the Company's consolidated financial statements.

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 those risks and uncertainties
described in our Form 10-K for the year ended December 31, 2001.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The mitigating actions enumerated above under "Foreign Currency Exchange Rate
Risks" in Management's Discussion and Analysis of Financial Condition and
Results of Operations and in Management's Discussion and Analysis of Financial
Condition and Results of Operations contained in the Company's Annual Report on
Form 10-K have effectively mitigated the impact of exchange rate fluctuations
and credit risk on the Company's results of operations and financial position to
a level which is not material.
