1. General



Millipore Corporation is a multinational life science company that provides innovative tools, technologies, and services to optimize the development and
manufacturing of biopharmaceuticals and to improve laboratory productivity. We offer a broad range of high-performance products and services based on membrane, chromatographic and other enabling technologies.



Our interim fiscal quarters end on the thirteenth Saturday of each quarter.
Since our fiscal year-end is December 31, the first and fourth fiscal quarters may not consist of precisely thirteen weeks. The third fiscal quarter of 2005 and 2004 ended on October 1, 2005 and October 2, 2004, respectively.



The accompanying unaudited condensed consolidated financial
statements have been prepared in accordance with the accounting principles generally accepted in the United States and instructions to Form 10-Q and, accordingly, these footnotes condense or omit information and disclosures which substantially
duplicate information provided in our latest audited financial statements. These financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended
December 31, 2004.



Certain reclassifications have been
made to prior years financial statements to conform to the 2005 presentation.



In the opinion of our management, these financial statements reflect all adjustments necessary for a fair statement of the results for the interim periods presented. The accompanying unaudited condensed consolidated
financial statements are not necessarily indicative of future trends or our operations for the entire year.



2. Stock-Based Compensation



We grant stock options and award restricted stock as part of our stock-based employee compensation plan. We also grant stock options from our non-employee director stock option plan. As permitted under Statement of Financial Accounting
Standards (SFAS) No. 123, Accounting for Stock-Based Compensation, we apply the recognition and measurement provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for
Stock Issued to Employees, and related interpretations in accounting for these plans. No stock-based employee compensation expense has been recorded in connection with the issuance of employee and director stock options as all options
granted under these plans were fixed awards and had an exercise price equal to the market value of our common stock at the date of grant. Stock-based employee compensation expense in relation to the separation agreements for the former Chief
Executive Officer and certain other executive officers and the vesting of restricted stock granted to employees is reflected in net income.



SFAS No. 123, as amended by SFAS No. 148, Accounting for Stock-Based Compensation-Transition and Disclosure, an Amendment of FASB
Statement No. 123, requires the presentation of certain pro forma information as if we had accounted for our stock-based employee compensation under the fair value method. For purpose of this disclosure, the fair value of the fixed
option grants was estimated using the Black-Scholes option-pricing model with the following weighted average assumptions:

3. Business Acquisitions



On August 9, 2005, we acquired approximately 90% of
the outstanding shares of NovAseptic A.B. (NovAseptic) stock from its majority shareholders for $85,812 in cash, subject to certain post-closing adjustments. On September 14, 2005, we completed the acquisition of the remaining
shares from the minority shareholders for $9,369 in cash. Total purchase price was $96,296, including acquisition costs and post-closing adjustments. NovAseptic provides innovative solutions for aseptic processing applications in biotechnology and
pharmaceutical manufacturing operations. The acquisition was recorded as a purchase business combination.



On July 4, 2005, we acquired 100% of the outstanding common stock of MicroSafe B.V. (MicroSafe), a European contract laboratory that
develops assays and provides testing services to help biotechnology and pharmaceutical customers monitor quality and compliance in the drug manufacturing process. The total purchase price was $9,088 in cash, including acquisition costs. The
acquisition of MicroSafe enables us to participate in the outsourcing trend in the biotechnology industry. The acquisition was recorded as a purchase business combination.



The purchase prices for the NovAseptic and MicroSafe acquisitions have been allocated, on a preliminary basis, to the
acquired tangible assets and liabilities, identifiable intangible assets and goodwill based on their estimated fair value at the time of acquisition. The aggregate excess purchase price over the fair value of net tangible assets and liabilities
acquired was allocated, on preliminary basis, to identifiable intangible assets and goodwill as follows:



|                                          |  |        |         |                                     |

The excess purchase
price allocated to intangible assets and goodwill is not deductible for income tax purposes. The amount allocated to the in-process research and development costs was written off at the date of acquisition because these costs had no alternative
future uses and had not reached technological feasibility. The write-off is included in the research and development expenses in the condensed consolidated statement of income for the three months ended October 1, 2005.

We expect to
contribute $1,513 to our U.S. pension plan, $901 to our foreign pension plans, and $582 to our other postretirement benefit plans for 2005. As of October 1, 2005, we have made $1,197, $843, and $484 of contributions to the U.S. pension plan,
the foreign pension plans and the other postretirement benefit plans, respectively.



The Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act) introduced a prescription drug benefit under Medicare as well as a federal subsidy to sponsors of retiree healthcare
benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. In May 2004, the Financial Accounting Standards Board (the FASB) issued FASB Staff Position (FSP) No. 106-2,
Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003. As permitted under FSP No. 106-2, we elected to defer the accounting for the Act until the issuance
of authoritative guidance on the determination of actuarial equivalence for purposes of receiving the federal subsidy. On January 21, 2005, the Center for Medicare and Medicaid Services released the final regulations implementing the Act. Based
on these final regulations, we determined that most benefits provided by the plan are at least actuarially equivalent to Medicare Part D. The effect of the federal subsidy to which we are entitled has been accounted for as an actuarial gain of
$1,308. The subsidy will reduce postretirement benefit expense for 2005 by $203. In addition to accounting for the federal subsidy as a result of Medicare Part D, the plans actuarial assumptions were changed to reflect an expected future
reduction in our HMO plan cost as a result of the Act. This change in assumptions resulted in an actuarial gain of $872 and a reduction in benefit expense for 2005 of $100.

Share (continued)



For the three months ended October 1, 2005 and October 2, 2004, outstanding stock options of 22 and 2,953,
respectively, with exercise prices in excess of the average fair market value of our common stock for the related period, were excluded from the calculation of diluted net income per share because their inclusion would have been antidilutive. For
the nine months ended October 1, 2005 and October 2, 2004, outstanding stock options of 1,531 and 2,777, respectively, with exercise prices in excess of the average fair value of our common stock for the related period, were excluded from
the calculation of diluted net income per share because their inclusion would have been antidilutive. Antidilutive options could become dilutive in the future.

11. Commitments and Contingencies



During the first quarter of 2004, an issue arose under
our tax sharing agreement with our former subsidiary, Mykrolis Corporation (Mykrolis), which subsequently merged with Entegris Inc., relating to the inclusion of Mykrolis in our consolidated tax return for portions of 2001 and 2002. The
tax sharing agreement provides that if Millipore receives a tax benefit (as defined in the agreement) due to the inclusion of Mykrolis in our consolidated tax return, Millipore is required to pay Mykrolis the amount of that benefit. During the first
quarter of 2004, we made a payment to Mykrolis in the amount of $1,255 pursuant to the tax sharing agreement. Mykrolis has questioned the methodologies underlying the calculation of the tax benefit. We believe that we have properly calculated and
recorded amounts owed to Mykrolis.



12. Investments in Unconsolidated
Companies



We have equity investments in two companies
which are accounted for using the equity method. During the three and nine months ended October 1, 2005, we recorded $543 and $1,259 of income and received $0 and $411 of dividends from these unconsolidated companies. During the three and nine
months ended October 2, 2004, we recorded $1,375 and $1,372 of income and received $129 and $514 of dividends from these unconsolidated companies.



13. Officer Compensation Agreements



On April 28, 2004, Francis J. Lunger announced that he would step down as CEO and President of Millipore. Mr. Lunger stepped down as CEO and
President as of December 31, 2004, and as Director and Chairman of Millipores Board of Directors as of March 1, 2005. In connection with Mr. Lungers separation agreement, we recorded an aggregate of $7,520 in compensation
expense, including $2,501 for severance, bonus and related benefits and $5,019 related to stock options. In 2005, we recorded $519 for severance, bonus and related benefits, and $3,242 for stock options.



On January 1, 2005, Dr. Martin D. Madaus joined Millipore as
CEO and President, and as a director. Dr. Madaus became Chairman of Millipores Board of Directors on March 1, 2005. In 2005, we reimbursed Dr. Madaus $1,819 for certain compensation from his former employer forfeited by his
acceptance of Millipores employment offer. The compensation is a combination of $1,433 of cash and 8 shares of restricted stock with a fair market value of $386. The fair value of the restricted stock was recorded as unearned

compensation and will be amortized over the four-year restriction period. We also paid $94 for his relocation costs.



During the six months ended July 2, 2005, we recorded $6,219 of charges
related to separation agreements with certain other executive officers. These charges consisted of $4,004 related to severance, bonus and other related benefits, and $2,215 related to stock options as a result of modification of certain options
pursuant to the separation agreements.



14. New Accounting Pronouncements



In November 2004, the FASB issued SFAS No. 151,
Inventory Costs, an amendment of ARB No. 43, Chapter 4. SFAS No. 151 amends the guidance in Accounting Research Bulletin No. 43, Chapter 4, Inventory Pricing, to clarify the accounting for
abnormal amounts of idle facility expense, freight and handling costs, and wasted material (spoilage). SFAS No. 151 requires that those items be recognized as current period charges. In addition, SFAS No. 151 requires that allocation of
fixed production overheads to the conversion costs be based on the normal capacity of production facilities. SFAS No. 151 will be effective for us for the first quarter of 2006. We are in the process of evaluating the impact of SFAS
No. 151 on our consolidated financial statements.



In
December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R), which replaces SFAS No. 123, Accounting for Stock-Based Compensation, and supersedes
APB Opinion No. 25. SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. The pro forma footnote disclosure
alternative is no longer allowable under SFAS No. 123R. On March 29, 2005, the Securities and Exchange Commission (the SEC) issued Staff Accounting Bulletin No. 107 to express the SEC staffs views regarding the
interaction between SFAS No. 123R and certain SEC rules and regulations and provide the staffs views regarding the valuation of share-based payment arrangements. SFAS No. 123R will be effective for us for the first quarter of 2006.
We are in the process of assessing the impact of expensing stock options on our consolidated financial statements.



The American Jobs Creation Act of 2004 (the AJCA) contains a number of provisions which will affect us in the future. One provision of the AJCA establishes a
special deduction for Qualified Domestic Production Activities for U.S. manufacturers. The special deduction starts at 3% of Qualified Production Income (QPI) as defined in the AJCA in 2005 and will be 9% of QPI
when fully phased in after 2009. In December 2004, the FASB issued FSP No. 109-1, Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by
the American Jobs Creation Act of 2004. FSP No. 109-1 requires that qualified domestic production activities deductions should be accounted for as a special deduction in accordance with SFAS No. 109, Accounting for
Income Taxes, and that the related impact of this deduction should be reported in the period in which the deduction is claimed on tax returns. We are currently projecting a tax loss on our 2005 U.S. tax return. Therefore, we do not
currently believe there is a benefit to us from the qualified domestic production activities deduction.



A second provision of the AJCA provides a temporary incentive for a U.S. company to repatriate earnings deemed to be permanently reinvested outside the
U.S., at a reduced effective tax rate of approximately 5.25%. In December 2004, the FASB issued FSP No. 109-2, Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of
2004, to address the appropriate point at which a company should reflect in its financial statements the effects of the one-time tax benefit on the repatriation of foreign earnings. The FASB provided companies with additional time beyond
the financial reporting period to evaluate the effect of the AJCA on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. While we have not made a decision to repatriate earnings under the AJCA,
we are studying the AJCA and recent IRS guidance to determine whether it would be beneficial for us to make use of the temporary incentive in 2005. If we decide to repatriate the maximum amount of $500 million allowed to us under the provisions of
the AJCA, we will incur approximately $26 million of income taxes, which would be recorded in the fourth quarter of 2005.

14. New Accounting Pronouncements
(continued)



In March 2005, the FASB issued Interpretation No. 47 (FIN 47), Accounting for Conditional
Asset Retirement Obligations  an interpretation of FASB Statement No. 143. FIN 47 clarifies that the term conditional asset retirement obligation refers to a legal obligation to perform an asset retirement activity
in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of an entity. An entity is required to recognize a liability for the fair value of a conditional asset retirement obligation
if the fair value of the liability can be reasonably estimated. The fair value of a liability for the conditional asset retirement should be recognized when incurred  generally upon acquisition, construction, or development and/or through the
normal operation of the asset. FIN 47 will be effective for us as of the end of 2005. Retrospective application of this standard to interim financial statements is not required. We are in the process of assessing the impact of FIN 47 on our
consolidated financial statements.

|Item 2. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------



Basis of Presentation



The following Managements Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our Condensed
Consolidated Financial Statements and related notes thereto and other financial information included elsewhere in this Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2004. Throughout this discussion, references
will be made to constant currencies. Constant currency is a non-GAAP measure whereby foreign currency balances are translated, for all periods presented, at Millipores predetermined budgeted exchange rates for 2005, thus excluding
the impact of fluctuations in the actual foreign currency exchange rates. In addition to analyzing U.S. GAAP financial results, we also analyze our results in constant currencies as we believe these measures may allow for a better understanding of
the underlying business trends. The U.S. dollar results represent the foreign currency balances translated at actual exchange rates. Our interim fiscal quarters end on the thirteenth Saturday of each quarter. Since our fiscal year-end is
December 31, the first and fourth fiscal quarters may not consist of precisely thirteen weeks. The third fiscal quarter for 2005 and 2004 ended on October 1, 2005 and October 2, 2004, respectively.



During the second quarter of 2005, as part of our strategic reorganization,
we announced the formation of two divisions, Bioprocess and Bioscience. The Bioprocess division offers our customers solutions to optimize development and manufacturing of biopharmaceuticals. The Bioscience division, which consisted of our former
Laboratory Water and Life Science operating segments, provides products and application insights that improve laboratory productivity.



Executive Summary



During the three months ended October 1, 2005 (the third quarter of 2005), we acquired MicroSafe, B.V. (MicroSafe) and
NovAseptic A.B. (NovAseptic). MicroSafe develops assays and provides testing services to help biotechnology and pharmaceutical customers monitor quality and compliance in the drug manufacturing process. MicroSafe enhances growth in our
Bioprocess divisions process monitoring tools business and enables us to participate in the outsourcing trend in the biotechnology industry. NovAseptic provides innovative solutions for aseptic processing applications in biotechnology and
pharmaceutical manufacturing operations and is an excellent strategic fit for our process monitoring tools business as well as our systems and components businesses. Both acquisitions have been included in our Bioprocess division.



During the third quarter of 2005 as compared with the three months ended
October 2, 2004 (the third quarter of 2004), our sales growth was 14%, comprised of a 13% growth in constant currencies and a 1% foreign currency impact. Our NovAseptic and MicroSafe acquisitions accounted for 2% of the constant
currency sales growth. The strong growth was across both Bioprocess and Bioscience divisions. Sales of the Bioprocess division increased 16% at actual and constant currency rates of exchange. Sales of the Bioscience division increased 10% at actual
exchange rates and 9% in constant currencies. Both divisions experienced strong growth in sales of consumables, hardware and services which, on a consolidated basis, were 19%, 11%, and 28% in constant currencies, respectively.



We received a large, one-time stocking order for consumables of approximately
$38 million from one of our major biotechnology customers in the second quarter of 2005. We recorded $1 million of revenue from this order during the third quarter of 2005 and expect approximately $6 to $7 million of revenue from this order in the
fourth quarter of 2005 with the remaining $30 million expected in 2006. However, if there are changes to the scheduled delivery dates in the future, some of this revenue may occur in 2007. Furthermore, it is possible that, at some time in the
future, this customer may choose to draw down their inventory, in which case the incremental revenue to our forecast will not be realized or will be less than what is currently anticipated.



During the nine months ended October 1, 2005 as compared with the nine
months ended October 2, 2004, our sales growth was 12%, comprised of a 10% growth in constant currencies and a 2% foreign currency impact. Sales of the Bioprocess division increased 14%, comprised of a 12% growth in constant currencies and a 2%
foreign currency impact. Sales of the Bioscience division increased 8%, comprised of a 5% growth in constant currencies and a 3% foreign currency impact. Geographically, the Americas have experienced the strongest constant currency growth at 11% in
the first nine months of 2005 as compared to the first nine months of 2004, primarily due to strong sales to pharmaceutical and biotechnology customers. Both divisions experienced strong growth in sales of consumables and services while sales of
hardware have demonstrated moderate growth.



Operating income
as a percentage of sales for the three and nine months ended October 1, 2005 declined as compared to the same periods in 2004. The year to date operating income was negatively impacted by purchase accounting charges related to our recent
acquisitions and three other discrete items: costs incurred to implement our manufacturing consolidation

strategy, expenses in connection with executive compensation agreements and costs associated with the reorganization of our divisions.



Our strategic manufacturing plan, which began in the fourth quarter of 2004
with the closing of our Japan manufacturing plant, will result, over five years, in the consolidation of the majority of our manufacturing activities into three major plants in New Hampshire, Ireland and France and, to a lesser extent, the
outsourcing of some of our manufacturing processes. As part of this five-year plan, we will cease production in our Billerica, Massachusetts plant, our Bedford, Massachusetts device plant and our Stonehouse, England plant in 2006, and our Puerto
Rico plant in 2008. Approximately 350 employees will be affected. The total cost of this program over the five-year period is expected to be approximately $55 million, of which approximately $10 to $12 million is expected in 2005 with the remainder
to be incurred in 2006 through 2008. We project that annual savings from this program will be approximately $40 million by 2009.



Critical Accounting Policies and Estimates



This discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which
have been prepared in accordance with accounting principles generally accepted in the United States of America. Our most critical accounting policies had a significant impact on the preparation of these condensed consolidated financial statements.
These policies include estimates and significant judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We continue to have the same critical accounting
policies and estimates as we described under Item 7, on page 13, in our Annual Report on Form 10-K for the year ended December 31, 2004. Those policies and estimates were identified as those relating to revenue recognition, allowance for
doubtful accounts, inventory valuation analysis, valuation of long-lived assets, income tax provision, employee pension and postretirement medical plans and our intention to refinance short-term debt on a long-term basis. We continue to evaluate our
estimates and judgments on an on-going basis. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. We base our estimates and judgments on historical experience and on various other assumptions that are
believed to be reasonable under the circumstances. Actual results may differ materially from these estimates under different assumptions or conditions.



With the acquisition of NovAseptic and MicroSafe during the third quarter, we allocated, on a preliminary basis, the purchase prices to the assets and
liabilities of the acquired entities based on their estimated fair values at the time of acquisition. Acquired assets included tangible and intangible assets, including goodwill and other identifiable intangibles. The identification and valuation of
these intangible assets and the determination of the estimated useful lives at the time of acquisition require significant management judgments and estimates. These estimates are made based on, among others, consultations with an accredited
independent valuation consultant and reviews of projected future cash flows. The use of different estimates and assumptions could increase or decrease the estimated fair value of our identifiable intangible assets and goodwill, and potentially
result in a different impact to our results of operations. Furthermore, changes in business strategy and/or market conditions may significantly impact these judgments thereby impacting the fair value of these assets, which could result in a future
impairment of the goodwill and other identifiable intangible assets.

In the Bioprocess
division, constant currency sales increased 16% during the third quarter of 2005 as compared with the third quarter of 2004, including 4% sales growth attributable to our NovAseptic and MicroSafe acquisitions. Consumables sales increased 14% due to
strong growth in sales of chromatography media and process scale filtration devices and our NovAseptic and MicroSafe acquisitions. Hardware sales grew 27% as a result of several large system sales in the third quarter of 2005. Hardware sales can
fluctuate significantly as they are driven by our customers timing for capacity expansion. Although services represent a small portion of Bioprocess division sales, our services revenue increased 114%, or $1.5 million, due to the strategic
emphasis placed on this portion of the business as evidenced by our MicroSafe acquisition.



In the Bioscience division, constant currency sales grew 9% during the third quarter of 2005 as compared with the third quarter of 2004. Strong demand for laboratory water purification equipment as well as consumable
products used in laboratory water purification, drug discovery and other general filtration applications was partially offset by declining sales of products used in OEM devices and genomics applications by life science laboratories. In addition,
services provided to customers for our water purification equipment grew 11% as the installed base of equipment continued to grow.

The Americas achieved
constant currency sales growth of 13%, primarily driven by strong sales in the Bioprocess division of consumable chromatography media, process scale filtration devices and system hardware as well as by the NovAseptic acquisition. In the Bioscience
division, U.S. sales of life science research consumables benefited as our customers increased spending for drug discovery projects. For both divisions, service revenues for equipment maintenance and validation studies continued their strong growth
pattern. In Europe, sales grew 14% in constant currencies as growth was strong across consumable and service product lines for both divisions. The NovAseptic and MicroSafe acquisitions also contributed to the strong growth in Europe. In the
Asia/Pacific region, constant currency sales growth of 12% reflected strong shipments of Bioscience consumables and laboratory water purification equipment as well as consumables sold to pharmaceutical companies and for process monitoring
applications. Also contributing to this growth was a price increase in Japan.

##### Table of Contents

During the third quarter of 2005, exchange rates for the U.S. dollar remained relatively flat. The U.S.
dollar strengthened against the Euro by less than 1% and against the Japanese Yen by approximately 1% during the third quarter of 2005 as compared with the third quarter of 2004.



Gross Profit Margins



Gross profit margin percentage was 51.2% in the third quarter of 2005 as compared with 53.8% in the third quarter of 2004. During the third quarter of
2005, our gross margin was negatively impacted by the sales of products acquired in connection with the NovAseptic acquisition as the value of the acquired inventories were written up to fair value under the purchase accounting rules. In addition,
we also recorded $4.1 million of expenses related to our manufacturing consolidation plan, including $2.9 million for severance costs, $0.9 million for accelerated depreciation and $0.3 million other costs related to our decision to outsource
certain manufacturing processes. The negative effect of these items on the gross margin was offset by slightly favorable foreign exchange impact.



Operating Expenses



Selling, general and administrative (SG&A) expenses increased $8.6 million, or 13%, in the third quarter of 2005 as compared with the
third quarter of 2004. The increased SG&A expenses related to the operating expenses of the acquired companies of $2.6 million, incentive compensation, salaries and outside services of $2.2 million, and other expenses of $3.8 million.



Research and development (R&D) expenses
increased $3.7 million, or 25%, in the third quarter of 2005 as compared with the third quarter of 2004. The increase during the third quarter of 2005 was primarily due to the write-off of $3.1 million of in-process R&D costs acquired in
connection with the NovAseptic acquisition.



Net Interest
Expense



Net interest expense decreased $1.3 million in
the third quarter of 2005 as compared with the third quarter of 2004. The lower net interest expense was principally a result of lower average debt outstanding and higher average cash balances. During the third quarter of 2005, the weighted average
interest rate on our revolving credit agreement was approximately 4.3%.



Provision for Income Taxes



Our effective tax
rate for the third quarter of 2005 was 25.5% as compared with 22.5% during the third quarter of 2004. Our annual effective tax rate for 2005 is now expected to be approximately 22.0%, without taking into consideration the negative impact from a
potential repatriation of foreign earnings during the fourth quarter of 2005 under the American Jobs Creation Act of 2004 (the AJCA), which is higher than the 21.0% annual effective tax rate projected in the second quarter of 2005. The
higher effective tax rate for the third quarter of 2005 and higher projected rate for the full year are primarily attributable to the write-off of non-deductible in-process R&D costs acquired in connection with our NovAseptic acquisition in the
third quarter of 2005.

In the Bioprocess
division, constant currency sales increased 12% during the first nine months of 2005 as compared with the first nine months of 2004. Consumables sales increased 12% due to strong growth in sales of chromatography media and process scale filtration
devices and as a result of our NovAseptic acquisition. Hardware sales grew by 8% primarily as a result of sales of equipment used to house and test the integrity of process scale filtration cartridges. Systems hardware sales remained flat in the
first nine months of 2005 as compared with the first nine months of 2004. Although services represent a small portion of Bioprocess division sales, our services revenue grew 70%, or $2.8 million, due to the strategic emphasis placed on this portion
of the business as evidenced by our MicroSafe acquisition.



In
the Bioscience division, constant currency sales grew 5% during the first nine months of 2005 as compared with the first nine months of 2004. Strong demand for consumable products used in laboratory water purification, drug discovery and other
general filtration applications was partially offset by declining sales of products used in OEM devices and genomics applications by life science laboratories. In addition, services provided to customers for water purification equipment grew 9% as
the installed base of equipment continued to grow.

The Americas achieved
constant currency sales growth of 11%, primarily driven by the Bioprocess division which experienced strong sales of consumable chromatography media and process scale filtration devices. Further, our customers increased their spending for drug
discovery projects, thereby supporting the demand for our consumables offerings. In Europe, the 10% constant currency sales growth was primarily due to a 13% growth in sales of chromatography and filtration consumables. Our NovAseptic and MicroSafe
acquisitions positively impacted sales growth in both the Americas and Europe. The growth in the Asia/Pacific region was modest.



During the first nine months of 2005, the U.S. dollar remained weaker on average as compared to the first nine months of 2004. A weaker U.S. dollar
positively impacts U.S. dollar sales growth because approximately 60% of our sales are outside the U.S. Since we have a higher percentage of our sales in Europe than in Asia, the impact of translating sales denominated in European currencies will
have a greater impact on our U.S. dollar sales than the impact of translating sales

denominated in Asian currencies. On average, the U.S. dollar weakened against the Euro by approximately 3% and against the Japanese Yen by approximately 1%
during the first nine months of 2005 as compared with the first nine months of 2004.



Gross Profit Margins



Gross profit margin percentage was 52.8% in the first nine months of 2005 as compared with 54.2% in the first nine months of 2004. During the first nine months of 2005, our gross profit margin was negatively impacted by the sale of products
acquired as part of the NovAseptic acquisition as the value of the acquired inventories were written up to fair value under the purchase accounting rules. In addition, during the first nine months of 2005, we also recorded $6.7 million expenses
related to our manufacturing consolidation plan, including $3.7 million for severance costs, $1.3 million of inventory write-offs as a result of our decision to outsource certain manufacturing processes, $1.4 million for accelerated depreciation,
and $0.3 million of other costs. The negative effect of these items on the gross margin was offset by favorable foreign exchange impact.



Operating Expenses



SG&A expenses increased $31.8 million, or 16%, in the first nine months of 2005 as compared with the first nine months of 2004. Our results for the
first nine months of 2005 reflected incremental $2.6 million operating expenses from the acquired companies and $12.2 million higher expenses related to officer compensation and other employee terminations. In addition, higher SG&A expenses for
the first nine months of 2005 included a $6.2 million increase related to incentive compensation and salaries and a $7.3 million increase in other costs, primarily for outside services, sales training and demolition costs for our Bedford campus. The
officer compensation and other employee severance costs included costs associated with CEO transition and termination agreements for certain executive officers and severance for other employees in connection with our decision in the first quarter of
2005 to combine our Laboratory Water and Life Science operating segments into one division. The demolition costs for our Bedford campus are for site preparation for our new R&D facility which will be completed in 2006.



R&D expenses increased $5.1 million, or 11%, in the first nine months of
2005 as compared with the first nine months of 2004. The increase during the nine months ended October 1, 2005 was due primarily to $3.1 million write-off for in-process R&D acquired in connection with the NovAseptic acquisition and $0.5
million employee severance in connection with our decision in the first quarter of 2005 to combine our Laboratory Water and Life Science divisions.



Net Interest Expense



Net interest expense decreased $3.4 million in the first nine months of 2005 as compared with the first nine months of 2004. The lower net interest
expense was principally a result of lower average debt outstanding and higher average cash balances. During the first nine months of 2005, the weighted average interest rate on the revolving credit agreement was approximately 3.9%.



Provision for Income Taxes



Our effective tax rate for the first nine months of 2005 was 22.4% as
compared with 22.5% for the first nine months of 2004. The slight decline in the effective tax rate is due to a decrease in the expected profits from higher tax rate jurisdictions primarily as a result of severance costs and certain other charges
recorded in the first nine months of 2005 as compared to the first nine months of 2004, offset by the write-off of in-process R&D costs acquired in connection with our NovAseptic acquisition.



Market Risk



We are exposed to market risks, which include changes in foreign currency
exchange rates and credit risk. We manage these market risks through our normal financing and operating activities and, when appropriate, through the use of derivative financial instruments.



Foreign Currency Exchange Rate Risk



We are exposed to foreign currency exchange rate risk inherent in sales, net
income and assets and liabilities denominated in currencies other than the U.S. dollar. The potential change in foreign currency exchange rates offers a substantial risk to us, as approximately 60% of our business is conducted outside of the U.S.,
generally in foreign currencies. Our risk management strategy currently uses forward contracts to mitigate certain foreign currency exposures. The intent is to offset gains and losses that occur on the underlying exposures, with gains and losses
resulting from the forward contracts that hedge these exposures. Principal hedged currencies include the Euro, Japanese Yen and British Pound. The periods of these forward contracts typically span less than three months. We held forward foreign
exchange contracts with U.S. equivalent notional amounts totaling $91.5 million at October 1, 2005. The fair value of these contracts was a loss of $0.4 million at

##### Table of Contents

October 1, 2005. Additionally, we are able to partially mitigate the impact that fluctuations in currencies have on our net income as a result of our
manufacturing facilities located in Europe, material sourcing and other spending which occur in countries outside the U.S. We do not enter into derivatives for trading or other speculative purposes, nor do we use leveraged financial instruments.



Although we attempt to manage our foreign currency exchange
risk through the above activities, when the U.S. dollar weakens against other currencies in which we transact business, generally sales and net income will be positively but not proportionately impacted.



Credit Risk



We are exposed to concentrations of credit risk in cash and cash equivalents
and trade receivables. Cash and cash equivalents are placed with major financial institutions with high quality credit ratings. The amount placed with any one institution is limited by policy. Trade receivables credit risk exposure is limited due to
the large number of established customers and their dispersion across different geographies.



Capital Resources and Liquidity



Cash flow provided from operations was $131.7 million in the first nine months of 2005 as compared with $107.9 million in the first nine months of 2004. The increase in cash flow from operations in the first nine months of 2005 was
primarily the result of significantly higher non-cash charges included in net income, higher tax benefit from our stock plan activities and increases in accounts payable, accrued expenses and other current liabilities partially offset by increases
in accounts receivable and inventories and decreases in other liabilities.



During the first nine months of 2005, we paid $101.3 million, net of cash acquired, in connection with the acquisitions of NovAseptic and MicroSafe. In addition, we invested $55.5 million in property, plant and
equipment and expect to spend an additional $30 million to $35 million during the remainder of 2005. Our largest projects for 2005 include the construction of our new research and development center in Bedford, Massachusetts and the buildout of a
new membrane production line in Cork, Ireland. As a result of our decision to close our manufacturing plant in Cidra, Puerto Rico, we have also decided to accelerate to 2006 the previously-postponed buildout of our existing building shell in our
Ireland facility.



During the first nine months of 2005, we
received $99.2 million proceeds from exercises of employee stock options and repaid $47.0 million of our revolver borrowings.



We expect to continue using cash flows from operations to invest in capital projects, fund acquisitions and/or to reduce debt. We believe that our
existing cash and cash equivalents, cash flows expected to be generated from future operating activities, our ready access to capital markets for competitively priced instruments and funds available under our revolving credit agreement will be
sufficient to meet our cash requirements for at least the next twelve to twenty-four months. We are in compliance with all of our debt covenants.



Legal Proceedings



We currently are not a party to any material legal proceeding.



New Accounting Pronouncements



In November 2004, the FASB issued SFAS No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4. SFAS No. 151
amends the guidance in ARB No. 43, Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight and handling costs, and wasted material (spoilage). SFAS No. 151 requires
that those items be recognized as current period charges. In addition, SFAS No. 151 requires that allocation of fixed production overheads to conversion costs be based on the normal capacity of production facilities. SFAS No. 151 will be
effective for us for the first quarter of 2006. We are in the process of evaluating the impact of SFAS No. 151 on our consolidated financial statements.



In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment (SFAS No. 123R), which
replaces SFAS No. 123, Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25. SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be
recognized in the income statement based on their fair values. The pro forma footnote disclosure alternative is no longer allowable under SFAS No. 123R. On March 29, 2005, the Securities and Exchange Commission (the SEC) issued
Staff Accounting Bulletin No. 107 to express the SEC staffs views regarding the interaction between FAS No. 123R and certain SEC rules and regulations and provide the staffs views regarding the valuation of share-based payment
arrangements. SFAS No. 123R will be effective for us for the first quarter of 2006. We are in the process of assessing the impact of expensing stock options on our consolidated financial statements.

The American Jobs Creation Act of 2004 (the AJCA) contains a number of provisions which will
affect us in the future. One provision of the AJCA establishes a special deduction for Qualified Domestic Production Activities for U.S. manufacturers. The special deduction starts at 3% of Qualified Production Income
(QPI) as defined in the AJCA in 2005 and will be 9% of QPI when fully phased in after 2009. In December 2004, the FASB issued FSP No. 109-1, Application of FASB Statement No. 109, Accounting for Income
Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004. FSP No. 109-1 requires that qualified domestic production activities deductions should be accounted for as a
special deduction in accordance with SFAS No. 109, Accounting for Income Taxes, and that the related impact of this deduction should be reported in the period in which the deduction is claimed on tax returns. We are currently
projecting a tax loss on our 2005 U.S. tax return. Therefore, we do not currently believe there is a benefit to us from the qualified domestic production activities deduction.



A second provision of the AJCA provides a temporary incentive for a U.S. company to repatriate earnings deemed to be
permanently reinvested outside the U.S., at a reduced effective tax rate of approximately 5.25%. In December 2004, the FASB issued FSP No. 109-2, Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within
the American Jobs Creation Act of 2004, to address the appropriate point at which a company should reflect in its financial statements the effects of the one-time tax benefit on the repatriation of foreign earnings. The FASB provided
companies with additional time beyond the financial reporting period to evaluate the effect of the AJCA on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. While we have not made a decision to
repatriate earnings under the AJCA, we are studying the AJCA and recent IRS guidance to determine whether it would be beneficial for us to make use of the temporary incentive in 2005. If we decide to repatriate under the provisions of the AJCA, a
tax provision for the related taxes will be recorded in the fiscal quarter in which the repatriation plan is approved. We will make a final determination by the end of 2005. If we decide to repatriate the maximum amount of $500 million allowed to us
under the provisions of the AJCA, we will incur approximately $26 million of income taxes, which would be recorded in the fourth quarter of 2005.



In March 2005, the FASB issued Interpretation No. 47 (FIN 47), Accounting for Conditional Asset Retirement Obligations  an
interpretation of FASB Statement No. 143. FIN 47 clarifies that the term conditional asset retirement obligation refers to a legal obligation to perform an asset retirement activity in which the timing and/(or) method of
settlement are conditional on a future event that may or may not be within the control of an entity. An entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability
can be reasonably estimated. The fair value of a liability for the conditional asset retirement should be recognized when incurred  generally upon acquisition, construction, or development and/(or) through the normal operation of the asset.
FIN 47 will be effective for us as of the end of 2005. Retrospective application of this standard to interim financial statements is not required. We are in the process of assessing the impact of FIN 47 on our consolidated financial statements.



Forward-Looking Statements



The matters discussed in this Form 10-Q, as well as in future oral and
written statements by our management, that are forward-looking statements are based on our current management expectations. These expectations involve substantial risks and uncertainties which could cause actual results to differ materially from the
results expressed in, or implied by, these forward-looking statements. Potential risks and uncertainties that could affect Millipores future operating results include, without limitation, foreign exchange rates; regulatory delay in the
approval of new therapeutics and their ultimate commercial success; competitive factors such as new membrane technology; lack of availability of raw materials or component products on a timely basis; inventory risks due to shifts in market demand;
change in product mix; conditions in the economy in general and in the bioscience and bioprocess markets in particular; potential environmental liabilities; the inability to utilize technology in current or planned products due to overriding rights
by third parties; the inability to successfully integrate acquired businesses; the inability to realize the expected benefits of development, marketing and other alliances; difficulties inherent in transferring or outsourcing of manufacturing
operations; difficulties inherent in research and development activities; and other risk factors and uncertainties described in our Form 10-K for the year ended December 31, 2004.
