1. General

Millipore is a leading global provider of products and services that improve productivity in biopharmaceutical manufacturing and in clinical, analytical and research laboratories.

The Companys interim fiscal quarter ends on the thirteenth Saturday of each quarter. Since the fiscal year-end is December 31, the first and
fourth fiscal quarters may not consist of precisely thirteen weeks. The second fiscal quarters of 2006 and 2005 ended on July 1, 2006 and July 2, 2005, respectively.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10
of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. The condensed consolidated balance
sheet as of December 31, 2005 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of the Companys
management, these condensed consolidated financial statements reflect all significant 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 the Companys operations for the entire year. These financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the
Companys Annual Report on Form 10-K for the year ended December 31, 2005.

Certain reclassifications have been made to the 2005
financial statements to conform to the 2006 presentation.

2. Stock-Based Compensation

On January 1, 2006, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (Revised 2004),
Share-Based Payment (SFAS No. 123(R)), which requires companies to recognize share-based payments to employees and directors as compensation expense using a fair value-based method in the results of operations.
Prior to the adoption of SFAS No. 123(R) and as permitted by SFAS No. 123, Accounting for Stock-Based Compensation, the Company accounted for share-based payments to employees using the intrinsic value method pursuant to
Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. Therefore, no stock-based employee compensation expense had 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 the Companys common stock at the time of the grant. Stock-based employee
compensation expense relating to separation agreements for certain executive officers and the vesting of restricted stock awards and restricted stock units granted at no cost to the employees was reflected in net income. Upon adoption of SFAS
No. 123(R), the Company elected to use the modified prospective method and, accordingly, did not restate the results of operations for the prior periods. Beginning on January 1, 2006, compensation expense has been recognized for all awards
granted on or after January 1, 2006 as well as for the unvested portion of awards granted before January 1, 2006.

Stock-based
compensation expense is estimated as of the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period. The Company estimates the fair value of its
stock options using the Black-Scholes option-pricing model and the fair value of its restricted stock awards and restricted stock units using the quoted market value of the Companys common stock. The Company recognizes the associated
compensation expense on a straight-line basis over the vesting periods of the awards, net of estimated forfeitures. Forfeiture rates are estimated based on historical pre-vesting forfeiture history and are updated on a quarterly basis to reflect
actual forfeitures of unvested awards and other known events.

Estimating the fair value for stock options requires judgment, including
estimating stock-price volatility, expected term, expected dividends and risk-free interest rates. The expected volatility rates are estimated based on historical volatilities of the Companys common stock over a period of time that
approximates the expected term of the options. The expected term represents the average time that options are expected to be outstanding and is estimated based on the historical exercise, post-

vesting cancellation and expiration patterns of the Companys stock options. Expected dividends are estimated based on the Companys dividend history as well as
managements current projections. The risk-free interest rate for periods approximating the expected terms of the options is based on the U.S. Treasury yield curve in effect at the time of grant. These assumptions will be updated at least on an
annual basis or when there is a significant change in circumstances that could affect these assumptions.

Pursuant to SFAS No. 123(R),
the Company reclassified the unearned compensation balance of $290 related to its restricted stock awards to additional paid-in capital as of January 1, 2006.

The following table presents stock-based compensation expense included in the Companys condensed consolidated statement of operations for the three and six months ended July 1, 2006:

The weighted average grant-date fair value of options granted during the three and six months
ended July 1, 2006 was $27.78 and $25.11 per option, respectively. The weighted average grant-date fair value of restricted stock units awarded during the three and six months ended July 1, 2006 was $73.34 and $67.08 per unit,
respectively. The weighted average assumptions used in the Black-Scholes option-pricing model for stock options granted during the three and six months ended July 1, 2006 were as follows:



|                        |  |                                 |   |  |                               |

|Risk-free interest rate |  | 5.0                             | % |  | 4.6                           | %
|Expected term           |  | 5 years                         |   |  | 5 years                       |  
|Expected dividends      |  |                                |   |  |                              |  

The Company did not capitalize any stock-based compensation related costs as such costs were not
material for the three and six months ended July 1, 2006. Unrecognized stock-based compensation expense was $27,206 at July 1, 2006 and is expected to be recognized over an estimated weighted average amortization period of 2.28 years. The
forfeiture rate used in the share-based compensation expense calculation for the three and six months ended July 1, 2006 was 4%.

As
required by SFAS No. 123(R), windfall tax deductions in excess of deferred tax assets from share-based compensation expense are reported as a financing cash inflow in 2006, rather than as an operating cash inflow as required under APB Opinion
No. 25. Under the modified prospective method, SFAS No. 123(R) does not permit the reclassification of the prior period cash flow statement.

Prior to its adoption of SFAS No. 123(R) on January 1, 2006, the Company applied the recognition and measurement provisions of APB Opinion No. 25 in accounting for stock-based compensation plans and
complied with the disclosure requirement under SFAS No. 123. The following table illustrates the effect on net income and earnings per share for the three and six months ended July 2, 2005 as if the Company had accounted for its
stock-based employee compensation under the fair value method:

The results of the acquired operations have been included in the condensed consolidated statements of operations since the date of acquisition. The
purchase price allocations related to this acquisition are based on preliminary information and are subject to change when additional data concerning final asset and liability valuations are obtained, however, management does not anticipate material
changes in the preliminary allocations. The excess purchase price allocated to intangible assets and goodwill is not deductible for income tax purposes. Pro forma results of operations have not been presented because such information is not material
to the Companys consolidated condensed financial statements.

NovAseptic A.B. and Microsafe B.V.

During the third quarter of 2005, the Company acquired NovAseptic A.B. (NovAseptic) and MicroSafe B.V. (MicroSafe) for $96,296 and
$9,088, respectively, including acquisition costs. NovAseptic provides innovative solutions for aseptic processing applications in biotechnology and pharmaceutical manufacturing operations while MicroSafe develops assays and provides testing
services that help biotechnology and pharmaceutical customers monitor quality and compliance in the drug manufacturing process. The purchase prices for the NovAseptic and MicroSafe acquisitions were allocated, on a preliminary basis, to the acquired
tangible assets and liabilities, identifiable intangible assets and goodwill based on their estimated fair values at the time of acquisition. In the second quarter of 2006, the Company finalized the allocation of the purchase price which resulted in
reductions to both goodwill and deferred tax liability. The final allocation is 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 was
included in the research and development expenses in the condensed consolidated statement of operations for fiscal year 2005.

For the three months ended July 1, 2006 and July 2, 2005, outstanding stock options of 315 and 2,932, respectively, that had 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 earnings per share because of their antidilutive effect. For the six months ended July 1, 2006 and July 2,
2005, outstanding stock options of 253 and 4,008, respectively, that had exercise prices in excess of the average fair value of our common stock for the related period were excluded from the calculation of diluted earnings per share because of their
antidilutive effect. Antidilutive options could become dilutive in the future. In addition, shares issuable upon conversion of the 3.75% convertible senior notes are excluded from the calculation of diluted earnings per share because the conversion
conditions had not been satisfied as of July 1, 2006 and the inclusion of these contingently issuable shares would be antidilutive.

7.5% senior notes due 2007

The Company has 7.5% ten-year unsecured notes of $100,000 due in April 2007. Interest is payable semi-annually in April and October. As of July 1,
2006, the notes were classified as short term debt and had a fair market value of $100,991.

Revolving credit facility

The Company entered into an agreement for a five-year unsecured revolving credit facility (the Revolver) in December 2005. The acquisition
of Serologicals Corporation (Serologicals) on July 14, 2006 and the related financing required the Company to change certain terms of the Revolver agreement. Accordingly, the Company amended the agreement in June 2006 (some of which
became effective on July 14, 2006) to:



| |  |  | permit the consummation of the Serologicals acquisition and issuance and incurrence of certain additional indebtedness in connection with the acquisition;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | extend the maturity date to June 6, 2011;
| | - |  | -----------------------------------------



| |  |  | require interest rate and commitment fee adjustments based on specified credit ratings;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | require the pledge of substantially all of the Companys assets to secure its obligations under the Revolver if specified credit rating levels are reached; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | adjust certain restrictions and financial covenants.
| | - |  | ----------------------------------------------------

The
Company further amended the Revolver agreement in July 2006 to increase the borrowing availability under the domestic facility from 430,000, or $550,083, to 465,000, or $594,857.

The Company is required to pay a commitment fee ranging between 0.0675% and 0.60% annually, based on the debt rating, on unused commitments. As of
July 1, 2006, the Company had 64,000, or $81,873, available for borrowing on the Revolver.

The Company is required to maintain
certain leverage and interest coverage ratios set forth in the Revolver agreement. As of July 1, 2006, the Company was compliant with all financial covenants specified in the amended credit agreement. The agreement also includes limitations on
the Companys ability to incur additional indebtedness to merge, consolidate, or sell assets, to create liens, and to make payments in respect of capital stock or subordinated debt, as well as other customary covenants and representations.

As of July 1, 2006, the Company borrowed 366,000, or $468,210, under the Revolver and the borrowings were classified as long-term debt because
of the Companys ability and intent to continuously refinance such borrowings. The Company used the borrowings, in part, to complete the acquisition of Serologicals on July 14, 2006. The Company recorded $2,806 of deferred financing costs
associated with amending the Revolver agreement and will amortize the costs over five years. For the first six months of 2006, the weighted average interest rate for the Revolver was 3.1%.

3.75% convertible senior notes due 2026

In June 2006, the Company issued $565,000 in aggregate principal amount of convertible senior notes (the Convertible Notes) in a private placement offering. The Convertible Notes bear interest at 3.75% per annum, payable
semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2006. Commencing with the six-month period beginning on December 1, 2011, if the average trading price of the Convertible Notes for the five
consecutive trading days preceding such six-month periods equals 120% or more of the principal amount, contingent interest (the Contingent Interest feature) will accrue on the Convertible Notes at the rate of 0.175% of the average
trading price of the Convertible Notes. The Convertible Notes are senior unsecured obligations and rank equally with all of the Companys existing and future senior unsecured indebtedness. The Convertible Notes are effectively subordinated to
all of the Companys existing and future secured indebtedness and all existing and future liabilities of the Companys subsidiaries, including trade payables. The Convertible Notes will mature on June 1, 2026. The Company used the net
proceeds from this offering to complete the acquisition of Serologicals on July 14, 2006. The Company recorded $13,361 of deferred financing costs associated with the issuance of the Convertible Notes and will amortize the amount over 5.5
years.

Holders of the Convertible Notes may convert their notes into cash and, if applicable, shares of Millipores common stock
prior to June 1, 2026 under certain conditions. The Convertible Notes may be converted if the closing sale price of Millipores common stock for each of the 20 or more trading days in a period of 30 consecutive trading days ending on the
last trading day of the immediately preceding calendar quarter exceeds 120% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter. The Convertible Notes may also be converted during the five
consecutive business days immediately after any five consecutive trading day period in which the average trading price per $1,000 principal amount of the Convertible Notes was equal to or less than 97% of the average conversion value of the notes
during this period. The Convertible Notes will also be convertible if the Company makes certain distributions on its common stock or engage in certain transactions, if the Company calls the Convertible Notes for redemption, and at any time from
November 1, 2011 through December 1, 2011 and any time on or after June 1, 2024. Upon conversion, the Convertible Notes will be convertible into cash for the principal amount and shares of Millipores common stock for the
conversion premium, if any, based on an initial conversion rate of 11.0485 shares per $1,000 principal amount (which represents an initial conversion price of approximately $90.51 per share), subject to adjustments.

On or after December 1, 2011, the Company has the option (the Call Option) to redeem the Convertible Notes at a redemption price equal
to 100% of the principal amount of the notes, plus accrued but unpaid interest. On each of December 1, 2011, June 1, 2016 and June 1, 2021, holders of the Convertible Notes have the option (the Put Option) to require
the Company to purchase all or a portion of their notes at a purchase price in cash equal to 100% of the principal amount of the notes, plus accrued but unpaid interest. Holders may also require the Company to repurchase all or a portion of their
notes upon a fundamental change at a repurchase price in cash equal to 100% of the principal amount of the notes to be repurchased, plus accrued but unpaid interest.

A holder that surrenders the Convertible Notes for conversion in connection with a make-whole fundamental change that occurs before December 1, 2011 may in certain circumstances be entitled to an
increased conversion rate (the Make-whole Payment). However, in lieu of increasing the conversion rate applicable to those Convertible Notes, the Company may in certain circumstances elect to adjust the conversion rate and the related
conversion obligation so that the Convertible Notes will be convertible into shares of the acquiring companys common stock, except that the principal return due upon conversion will continue to be payable in cash.

transaction. The Company is required to file an effective shelf registration statement under the Securities Act within 180 days after issuance of the Convertible Notes for the resale of the Convertible Notes and the shares of common stock issuable
upon conversion of the Convertible Notes. In the event that the Company fails to file an effective registration statement, the Company will be required to pay additional interest equal to 0.25% per annum of the aggregate principal amount of the
Convertible Notes for the 90-day period beginning on the date of the registration default and thereafter at a rate per year equal to 0.50% (Additional Interest). The Company has fulfilled this obligation by filing the required
registration statement on Form S-3 on August 9, 2006.

Although it is not required to maintain any specified financial ratios under the
Convertible Notes agreement, the Company will be considered in default if it fails to fulfill its conversion or redemption obligations, make required interest payments, provide notice to holders of the Convertible Notes in certain specified
circumstances, or cure its default on any indebtedness of its or its subsidiaries in the aggregate principal amount of $50,000 or more. If an event of default has occurred and is continuing, the principal amount of the Convertible Notes plus
interest thereon may become immediately due and payable. The Company is currently in compliance with the covenant restrictions.

As of
July 1, 2006, the Convertible Notes had a fair market value of $560,085. The Company evaluated the Convertible Notes agreement for potential embedded derivatives under SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities (SFAS No. 133) and related applicable accounting literature, including Emerging Issues Task Force (EITF) Issue No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially
Settled in, a Companys Own Stock, and EITF Issue No. 05-4, The Effect of a Liquidated Damages Clause on a Freestanding Financial Instrument Subject to Issue No. 00-19. The conversion feature, the Make-whole Payment, the Put
Option of the holder and the Call Option of the Company were determined to not meet the embedded derivative criteria as set forth by SFAS No. 133. Therefore, no fair value has been recorded for these items. The Contingent Interest feature and the
conversion feature related to the trading price of the Convertible Notes represent embedded derivatives that require separate recognition of fair value apart from the Convertible Notes under SFAS No. 133. As a result, the Company is required to
separate the value of these items from the Convertible Notes and record a liability on the consolidated balance sheet. As of July 1, 2006, both the Contingent Interest feature and the conversion feature had a nominal value, and therefore were
not recorded in the consolidated financial statements. The Company will continue to evaluate the materiality of the value of these items on a quarterly basis and record the resulting adjustment, if any, in the consolidated balance sheet and
statement of operations. The Company evaluated the Additional Interest provision of the registration rights clause in accordance with EITF Issue No. 05-4 and concluded that the item should be evaluated separately as a liability. The
Company did not believe it was probable that it would default on its registration obligation and therefore did not record any liability in connection with this provision as of July 1, 2006.

5.875% senior notes due 2016

In June
2006, the Company issued 250,000, or $319,816, in aggregate principal amount of 5.875% senior notes (the Euro Notes) due 2016. Interest is payable semi-annually in arrears on June 30 and December 30 of each year,
beginning on December 30, 2006. The Euro Notes were issued at 99.611% of the principal amount, which resulted in an original issue discount of 973, or $1,244. The Euro Notes will be senior unsecured obligations and will rank equally with
all of the Companys existing and future senior unsecured indebtedness. The Company used the net proceeds from this offering to complete the acquisition of Serologicals on July 14, 2006. The Company recorded $3,321 of estimated deferred
financing costs associated with the issuance of the Euro Notes and will amortize the amount over 10 years.

If the acquisition of
Serologicals were not consummated, the Company would be required to repurchase the Euro Notes on or before October 31, 2006 (the Repurchase Obligation) at a redemption price, payable in cash, equal to 101% of the principal amount, plus
accrued and unpaid interest. Upon the occurrence of any change in control, holders of the Euro Notes may require the Company to repurchase all of their Euro Notes (the holders Put Option) for a cash price equal to 101% of the
principal amount, plus accrued and unpaid interest thereon. Before June 30, 2016, the Company may at its option redeem the Euro Notes (call options), in whole or in part, for cash, at a redemption price equal to 100% of the
principal amount of the Euro Notes it redeems, plus applicable make-whole premium. In addition, the Company may redeem at its option (call options) in whole, but not in part, at a redemption price equal to 100% of the
principal amount, plus accrued and unpaid interest, upon the occurrence of certain tax events in the United States.

The indenture for the Euro Notes places certain restrictions on the Companys ability to create, incur, assume or suffer liens on its manufacturing
plants and other facilities in the United States and ability to enter into certain sales and lease-back transactions. The Company would also be considered in default if it fails to fulfill its redemption obligations, make required interest payments,
provide notice to holders of the Euro Notes in certain specified circumstances, or cure its default on any indebtedness of its or its subsidiaries in the aggregate principal amount of $50,000 or more. If an event of default has occurred and is
continuing, the principal amounts of the Euro Notes plus any accrued interests thereon may become immediately due and payable. The Company is currently in compliance with the covenant restrictions.

As of July 1, 2006, the Euro Notes had a fair market value of 249,028, or $318,572. The Company evaluated the Euro Notes agreement for
potential embedded derivatives under SFAS No. 133 and determined that the Companys call options, the holders Put Option, and the Companys Repurchase Obligation do not meet the embedded derivative criteria as set forth by SFAS No.

11. Stock Plans

As of
April 1, 2006, the Company had two share-based compensation plans, the 1999 Stock Incentive Plan (the 1999 Plan) and the 1999 Stock Option Plan for Non-Employee Directors (the Directors
Plan). On April 26, 2006, the Companys shareholders approved amendments to the 1999 Plan to permit awards of equity incentive compensation to non-employee directors of the Company under the 1999 Plan and to add to the 1999 Plan the
119 shares of the Companys common stock then remaining available for grant under the Directors Plan. Also, as of April 26, 2006, the Directors Plan was terminated, except that any option grant previously made under the
Directors Plan remained in effect pursuant to its terms.

The 1999 Plan, as in effect at July 1, 2006, allowed for the issuance
of a total of 11,321 shares of common stock, of which 119 represent new shares from the Directors Plan. The types of awards permitted under the 1999 Plan include stock options, restricted stock, stock appreciation rights and stock units
(including restricted stock units). The Company may condition the grant or vesting of awards on the satisfaction of performance conditions. The exercise price of the stock options may not be less than the fair market value of the Companys
common stock at the time of grant. Stock options generally vest over a four-year period and expire no later than ten years from the date of grant. Restricted stock awards represent shares of common stock issued to employees subject to forfeiture if
the vesting conditions are not satisfied. Restricted stock units represent the right to receive shares of common stock upon meeting specified vesting requirements. The vesting conditions for the Companys restricted stock awards and restricted
stock units are determined by the Board of Directors at the time of grants. Restricted stock and restricted stock units, which are awarded at no cost to employees, cannot be sold, assigned, transferred or pledged during the restriction period. The
restriction or vesting period ranges from two to four years. In most instances, shares are subject to forfeiture should employment terminate during the restriction period.

The following table summarizes the stock option activities for the Companys stock plans:

The following table summarizes information related to the outstanding and vested options as of July 1, 2006:



|                                                       |  |                     |        |                |   |

|Weighted average exercise price                        |  | $                   | 46.72  |                | $ | 45.81

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value,
based on the Companys closing common stock price of $62.99 as of June 30, 2006. This intrinsic value represents the value that would have been received by the option holders had option holders exercised all of their options as of that
date. Intrinsic value for stock options is defined as the difference between the current market value and the grant price. The total intrinsic value of options exercised during the three months and six months ended July 1, 2006 was $2,814 and
$27,211, respectively.

The following table summarizes the status of unvested restricted stock awards and restricted stock units as of
July 1, 2006 as well as changes during the three and six months ended July 1, 2006:

The Company expects to contribute $1,037 to the U.S. retirement plan, $1,199 to the foreign
retirement plans, and $628 to the other postretirement benefit plans in 2006. As of July 1, 2006, the Company made contributions of $556, $647, and $316 to the U.S. retirement plan, the foreign retirement plans, and the other postretirement
benefit plans, respectively.

13. Investments in Unconsolidated Companies and Variable Interest Entity

The Company has an equity investment in a South African company that is accounted for using the equity method. During the three and six months ended
July 1, 2006, income of $374 and $442, respectively, was recorded in selling, general and administrative expenses in the consolidated statements of operations. During the three and six months ended July 2, 2005, income of $56 and $367,
respectively, was recorded in selling, general and administrative expenses in the consolidated statements of operations.

In addition, the
Company has an equity investment in an Indian joint venture (the India JV) that is engaged in the manufacture and sale of certain types of filtration systems and laboratory water purification systems. This investment was previously
accounted for using the equity method. In 2006, the Company identified this entity as a variable interest entity under the Financial Accounting Standards Board (the FASB) Interpretation No. 46(R), Consolidation of Variable
Interest Entities. As the Company is deemed the primary beneficiary, the financial results of this entity have been consolidated in Millipores consolidated financial statements beginning January 1, 2006. The entity had total net
assets of $6,789 at July 1, 2006.

14. Contingencies

The Company currently is not a party to any material legal proceeding and has no knowledge of any material legal proceeding contemplated by any governmental authority or third party. The Company is subject to a number
of claims and legal proceedings which, in the opinion of the Companys management, are incidental to the Companys normal business operations. In the opinion of the Company, although final settlement of these suits and claims may impact
the Companys financial statements in a particular period, they will not, in the aggregate, have a material adverse effect on the Companys financial position, cash flows or results of operations.

Following its decision to consolidate the results of its 40% owned Indian Joint-Venture (the India JV) in January 2006, the Company learned
as a result of its internal controls procedures that certain payment and commission practices at the India JV raise issues of compliance with the U.S. Foreign Corrupt Practices Act. Promptly upon learning of this, the Company through its Audit and
Finance Committee engaged outside counsel and commenced an investigation, and is currently implementing certain corrective actions. The Company has notified the Securities and Exchange Commission and the Department of Justice of this matter. The
operations and financial results of the India JV are not currently, and have not to date been, material to the Company.

15. New Accounting Pronouncements

In June 2006, the
Financial Accounting Standards Board issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes(FIN 48). FIN 48 prescribes a more likely than not threshold for financial statement recognition and
measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting
for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. FIN 48 will become effective as of January 1, 2007. The Company is currently evaluating the impact of FIN 48
on its financial statements.

16. Subsequent Events

On July 14, 2006, the Company completed the acquisition of Serologicals Corporation (Serologicals). This strategic acquisition will significantly strengthen the market position of the Companys
Bioscience division by expanding its product portfolio into fast growing markets such as drug discovery products and services, antibodies and stem cell research products. The acquisition will also facilitate the Companys entrance into the
upstream bioprocessing market by gaining a cell culture supplements offering for its Bioprocess division. The total purchase price was approximately $1.5 billion, including the assumption of debt. The acquisition was financed with cash on hand and
net proceeds from the issuance of the 3.75% senior convertible notes and the 5.875% senior notes.

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, 2005. 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 second fiscal
quarters for 2006 and 2005 ended on July 1, 2006 and July 2, 2005, respectively.

General Overview

Millipore is a leading global provider of products and services that improve productivity in biopharmaceutical manufacturing and in clinical, analytical
and research laboratories. We are organized into two operating divisions. Our Bioprocess division helps our pharmaceutical and biotechnology customers to optimize their manufacturing productivity, ensure quality, and scale up the production of
therapeutic drugs, including biologics. We facilitate drug production during both pre-clinical development and manufacturing scale-up after drug approval. Our Bioscience division helps to optimize laboratory productivity and workflows by providing
reagents, kits, and other enabling technologies and products for life science research and development. We have a deep understanding of our Bioscience customers needs and offer reliable and innovative tools, technologies, and services.

For the three months ended July 1, 2006, we reported higher revenues, operating profits, and earnings per share versus the prior year
comparable period.

Revenues for the 2006 second quarter of $273.8 million were $28.8 million, or 11.8%, higher than last year. Foreign
currency translation had an insignificant effect on the year-over-year comparison. After adjusting for the favorable effects of acquisitions, total revenue was 7.8% higher than last year. Both of our divisions contributed to this strong revenue
growth. Bioprocess division revenues in the 2006 second quarter were 12.8% higher than last year and, after adjusting for the favorable effects of foreign currency translation and business acquisitions, were 6.3% higher than last year. This organic
growth was driven primarily by higher sales of our core filtration and chromatography products. Bioscience division revenues in the 2006 second quarter were 10.1% higher than last year reflecting successful execution of programs to increase revenues
by aligning sales and product management, prioritizing key customer relationships, and implementing targeted sales and marketing campaigns. Our continuing investments in fast growing international markets, particularly China and India, have also
contributed to the year-over-year Bioscience business revenue growth.

The revenue increase in the 2006 second quarter was accompanied by a
17.2% increase in operating profit versus the prior year comparable period. Higher sales volume and a business mix favoring higher gross margin products more than offset the higher costs associated with adoption of the new accounting standard for
stock-based compensation (SFAS No. 123(R)), which amounted to $3.1 million. Execution of our supply chain initiatives is ahead of schedule and generating significant gross margin improvements. However, the financial effect of these improvements
was offset by the ongoing, expected costs of our continued execution of our supply chain initiatives.

Earnings per diluted share of $0.54
in the 2006 second quarter increased $0.07 per diluted share, or 13.7%, over the prior year comparable period. The increase reflected the improved operating results and higher net interest income attributable to investments associated with our
higher cash balances.

On July 14, 2006, we completed the acquisition of Serologicals Corporation (Serologicals) for
approximately $1.5 billion including the assumption of debt, as previously announced. The acquisition of Serologicals will significantly strengthen the market position of our Bioscience division by expanding its product portfolio into fast growing
markets such as drug discovery products and services, antibodies and stem cell research products. The acquisition will also facilitate our entrance into the upstream bioprocessing market by gaining a cell culture supplements offering for our
Bioprocess division. We expect to increase sales of Serologicals products in international markets such as Europe, Asia and Japan, where we have a significant sales and marketing presence. In connection with financing this acquisition, we
issued 3.75% convertible senior notes amounting to $565.0 million, 5.875% senior notes amounting to 250.0 million (approximately $320.0 million), and amended our revolving credit facility.

On April 27, 2006, we acquired Newport Bio Systems, Inc. (Newport) for $8.6 million
including the assumption of debt. Newport is a provider of process containers, tubing manifolds, and assembly systems for collecting, storing, and transferring process fluids used in biopharmaceutical production. The addition of Newports
single-use process containers, which include bags and liners, to our Mobius disposable solutions will broaden the scope of our disposable process equipment product offerings. By manufacturing all of the components of an integrated disposable
solution, we will be able to eliminate the need for our customers to validate multiple products from multiple suppliers. This acquisition reflects our strategic focus on increasing our presence in the disposable manufacturing market and builds on
our 2005 NovAseptic acquisition.

Bioprocess Division

Bioprocess revenues of $166.9 million for the three-month period ended July 1, 2006 increased $19.0 million, or 12.8%, from the prior year comparable
period. Revenue growth was primarily attributable to higher sales volume as a result of the strong demand for our products and the impact of 2005 acquisitions. Foreign currency translation and product pricing had an insignificant effect on the
year-over-year comparison. Business acquisitions represented approximately $9.8 million of the year-over-year revenue increase. Adjusting for the effects of foreign currency translation and business acquisitions, Bioprocess division revenues
increased $9.3 million, or 6.3%. From a geographic perspective, North America represented approximately half of the overall increase, which was driven primarily by sales of the core process filtration and chromatography media products. The majority
of the remaining sales increase was in Europe, which was also driven by growth in core products. From a product line perspective, growth in consumables revenues represented nearly all of the year-over-year revenue increase after adjusting for
foreign currency translation and business acquisitions.

Bioprocess revenues of $330.6 million for the six-month period ended July 1,
2006 increased $32.4 million, or 10.9%, from the prior year comparable period. Revenues for the first six months included an unfavorable foreign currency translation effect amounting to $7.5 million and a favorable business acquisition effect
amounting to $17.8 million versus the prior year comparable period. Adjusting for these items, Bioprocess revenues for the first six months increased $21.7 million, or 7.3%. As with the second quarter growth, the six-month revenue growth was largely
attributable to higher sales of our core process filtration and chromatography media products.

Bioscience Division

Bioscience division revenue of $106.9 million for the three-month period ended July 1, 2006 increased $9.8 million, or 10.1%, from the prior year comparable period. Foreign currency translation had an
insignificant effect on the year-over-year comparison. From a geographic perspective, the increase was primarily attributable to higher business levels in growing international markets, particularly in China and India. The year-over-year growth rate
in China was the highest of all of the Bioscience divisions international markets, reflecting our continued investment in sales and marketing infrastructure. The primary drivers of the higher revenue in India were higher customer demand. North
American revenues also contributed to the year-over-year increase, which was primarily attributable to strong demand for laboratory water products. The strong demand was primarily the result of successful implementation of our initiatives designed
to align sales and product management goals, prioritize key customer relationships, and implement targeted sales and marketing campaigns. A new product line introduction late in 2005 also contributed to the year-over-year increase.

From a product line perspective, higher consumables revenues represented roughly half of the overall segment revenue increase. This increase was
primarily attributable to our sales and marketing initiatives and the favorable effect associated with the timing of shipments to a large customer. Hardware revenues grew 15.2% year over year. The growth was primarily attributable to the higher
business levels in growing international markets and for laboratory water products. Higher service revenues grew 33.9% year over year as a result of our concerted effort to grow service as a business.

Bioscience revenue for the six-month period ended July 1, 2006 increased $14.7 million, or 7.4%. Revenues for the first six months included an
unfavorable foreign currency translation effect amounting to $5.6 million versus the prior year comparable period. Adjusting for the effect of foreign currency translation, Bioscience revenues for the first six months increased $20.3 million, or
10.3%. As with the second quarter growth, the six month revenue growth was attributable to strong demand for consumable products resulting from our sales and marketing initiatives, higher sales of laboratory water products, higher sales in growing
international markets, and a new product line launched late in 2005.

Gross Profit Margins

Gross profit margins of 52.4% and 52.8% for the three and six-month periods ended July 1, 2006, respectively, were 20 basis points and 70 basis
points lower than the prior year comparable periods. The decreases were primarily attributable to higher current year costs associated with our plant consolidation initiatives (primarily severance and accelerated depreciation) amounting to $3.8
million and $8.0 million for the three and six-month periods ended July 1, 2006, respectively. Stock-based compensation charges associated with the implementation of SFAS No. 123(R) also had an unfavorable effect on the year-over-year
comparisons. These costs and charges reduced gross profit margins by 250 basis points and 210 basis points for the three and six-month periods ended July 1, 2006, respectively, versus 100 basis points and 50 basis points in the prior year
comparable periods, respectively. Without these costs and charges, our gross profit margins have improved. The improvements were primarily the result of the successful execution of our supply chain initiatives and, to a lesser extent, a sales mix
favoring higher margin consumable products.

Operating Expenses

Selling, general and administrative (SG&A) expenses increased $6.3 million, or 7.9%, and $10.4 million, or 6.7%, in the three and
six-month periods ended July 1, 2006, respectively, versus the prior year comparable periods. The primary drivers of the higher SG&A expenses were increased headcount to support our sales and marketing initiatives in 2006, acquisitions made
in the third quarter of 2005 and in 2006, and investments in growing international markets. Increases in employee stock-based compensation expenses of $2.3 million and $4.2 million for the three and six-month periods, respectively, as a result of
adopting SFAS No. 123(R) on January 1, 2006 and integration planning expenses of $2.0 million in 2006 related to Serologicals acquisition also contributed to the year-over-year increase. The effect of the higher 2006 spending was
significantly offset by executive termination costs incurred in the three and six-month periods ended July 2, 2005 of $3.8 million and $11.6 million, respectively, and 2005 severance costs related to the consolidation of our former Laboratory
Water and Life Sciences divisions of $3.2 million and $3.7 million.

As a percentage of net sales, SG&A expenses were 31.4% and 30.8%
for the three and six-month periods ended July 1, 2006, respectively, versus 32.6% and 31.6% for the comparable periods last year.

Research and development (R&D) expenses increased $2.4 million, or 13.7%, and $4.7 million, or 14.1% in the three and six-month periods ended July 1, 2006, respectively, versus the prior year comparable periods. Higher
R&D expenses in

##### Table of Contents

2006 were primarily attributable to the acceleration of new product development, which was the result of prior year
project rationalization and prioritization efforts and process improvements. As a result of adopting SFAS No. 123(R) on January 1, 2006, charges related to employee stock-based compensation expense accounted for $0.4 million and $0.7
million of the year-over-year increase for the three and six-month periods ended on July 1, 2006, respectively. The increases were partially offset by $0.5 million severance charge related to the consolidation of our former Laboratory Water and
Life Sciences divisions in the second quarter of 2005 which did not recur in 2006.

As a percentage of net sales, R&D expenses were
7.2% and 7.0% for the three and six-month periods ended on July 1, 2006, respectively, as compared to 7.1% and 6.7% for the comparable prior year periods.

Purchased intangibles amortization increased $0.7 million and $1.4 million in the three and six-month periods ended on July 1, 2006, respectively, versus the prior year comparable periods. The increases were
attributable to our MicroSafe and NovAseptic acquisitions in the third quarter of 2005.

Interest Income (Expense)

Interest income increased $8.6 million and $14.9 million in the three and six-month periods ended on July 1, 2006, respectively, versus the prior
year comparable periods. The increases were primarily the result of investing the borrowings under our revolving credit facility established in December 2005.

Interest expense increased $6.2 million and $8.6 million for the three and six-month periods ended on July 1, 2006, respectively, versus the prior year comparable periods. The increases were attributable to
higher borrowings under our revolving credit facility as well as borrowings under the 3.75% convertible senior notes and the 5.875% senior notes issued in June 2006 in connection with the Serologicals acquisition. We financed the Serologicals
acquisition in July 2006 with our existing cash and the proceeds from these borrowings. The increases were also attributable to a commitment fee amounting to $1.3 million associated with a bridge loan commitment we secured in connection with the
acquisition of Serologicals. We expect to incur significantly higher net interest expense for the remainder of the calendar year.

Provision for Income Taxes

Our effective income tax rates were 21.3% and 21.9% for the three and six-month periods ended on
July 1, 2006, respectively, versus 19.6% and 21.0% for the comparable periods last year. The higher effective tax rates for 2006 were due to the expiration of the special U.S. possessions credit tax regime, which applied to our plant in Puerto
Rico in 2005, and because we expect that our income from higher tax jurisdictions will increase in 2006. We expect our full-year effective tax rate to increase with the completion of the Serologicals acquisition.

We continue to evaluate our tax reserves under SFAS No. 5, Accounting for Contingencies, which requires us to accrue for losses
we believe are probable and can be reasonably estimated. The amount reflected in the consolidated balance sheet at July 1, 2006 is considered adequate based on our assessment of many factors including, results of tax audits, past experience and
interpretations of tax law applied to the facts of each matter. It is reasonably possible that our tax reserves could be increased or decreased in the near term based on these factors. Our effective tax rate will likely be impacted in the period in
which such adjustments are deemed necessary.

Net Income and Earnings per Diluted Share

Earnings per diluted share grew 13.7% and 5.8% for the three and six-month periods ended on July 1, 2006, respectively, from prior year comparable
periods despite net income growth of 21.5% and 13.1%, respectively. Earnings per diluted share in 2006 as compared to the prior year were adversely affected by a higher number of weighted average shares of common stock outstanding as a result of
significant stock option exercise activity this year.

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 represents a substantial risk to us because approximately 65% of our business is conducted outside of the United States, generally in foreign currencies.

Our primary risk management strategy is to use forward contracts to hedge certain foreign currency transaction exposures. The intent of this strategy 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. dollar equivalent notional amounts totaling $174.2 million at July 1, 2006. The fair value of these contracts was a net gain of
$0.2 million at July 1, 2006.

Our risk management policy allows for hedging our net investments in foreign subsidiaries, using both
derivative and non-derivative instruments. On June 30, 2006, we issued 250.0 million Euro-denominated senior notes which would give rise to significant foreign exchange risk when the debt is remeasured into U.S. dollars at the end of each
period. As we designated these notes as an economic hedge of our net investments in European subsidiaries, the remeasurement gains and losses will be recorded in other comprehensive income instead of being recognized in the statement of operations.
Upon maturity, however, we could be exposed to significant exchange rate risk as we will be required to repay the debt at the then current market exchange rates which could be higher or lower than the rates at which we borrowed the debt on
June 30, 2006. A 10% strengthening or weakening of the Euro against the U.S. dollar will cause us to pay approximately $32.0 million more or less than what we received when we issued the notes on June 30, 2006.

We do not enter into derivatives for trading or other speculative purposes, nor do we use leveraged financial instruments.

Interest Rate Risk

We are exposed to
changes in interest rates in the normal course of our business operations as a result of our ongoing investing and financing activities, which include debt as well as cash and cash equivalents and other highly liquid marketable securities. As of
July 1, 2006, our debt portfolio was comprised of a combination of fixed and floating rate borrowings. Our exposure to interest rate risk primarily relates to our revolving credit facilities, under which the interest rates on our current
borrowings float with Euro Libor rates. The fair market value of long-term fixed interest rate debt is subject to interest rate risk. Generally, the fair market value of fixed interest rate debt will increase as interest rates fall and decrease as
interest rates rise. In addition, the fair value of our convertible notes is affected by our stock price. The total estimated fair value of our fixed rate debt at July 1, 2006 was $979.6 million. Fair values were determined from available
market prices, using current interest rates and terms to maturity. If interest rates were to increase or decrease by 1%, the fair value of our fixed rate debt would decrease or increase by approximately $40.7 million.

We assess our interest rate risks on a regular basis and do not currently use financial instruments to mitigate these risks.

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

We assess our liquidity in terms of our ability to generate cash to
fund our operating, investing, and financing activities. Our primary ongoing cash requirements will be to fund operating activities, capital expenditures, investments in businesses, product development, employee benefit plans, and debt service. Our
primary sources of liquidity are internally generated cash flows and borrowings under our revolving credit facility. Significant factors affecting the management of our ongoing cash requirements are the adequacy of available bank lines of credit and
our ability to attract long term capital with satisfactory terms. The sources of our liquidity are subject to all of the risks of our business and could be adversely affected by, among other factors, a decrease in demand for our products, our
ability to integrate investments in businesses, deterioration in certain financial ratios, and market changes in general.

We had cash inflows from operations of $24.2 million in the first six months of 2006 compared with
cash inflows of $77.5 million in the first six months of 2005. This decrease was primarily attributable to reductions in accrued income taxes payable and accrued expenses, increased inventory levels, and presentation of certain stock compensation
tax benefits as financing cash flows this year as opposed to operating cash flows last year, which was required by our adoption of SFAS No. 123(R) on January 1, 2006. The decrease in the accrued income taxes payable was primarily
attributable to United States tax payments this year of $11.0 million related to the repatriation of foreign earnings in accordance with the American Jobs Creation Act of 2004, taxes paid in foreign jurisdictions as a result of higher 2005 taxable
profits, and the utilization of net operating loss carryforwards that did not recur. The decrease in accrued expenses was primarily attributable to higher incentive compensation payments this year of approximately $7.0 million as a result of strong
business performance last year and significantly higher levels of executive severance accruals last year resulting from the implementation of our new strategy. Inventory levels increased $8.0 million which was primarily attributable to safety stock
required in anticipation of product line relocations in accordance with our plant consolidation initiatives. Days of supply in inventory increased by 16 days from 106 days at July 2, 2005 to 122 days at July 1, 2006. Days sales outstanding
increased by 2 days from 70 days at July 2, 2005 to 72 days at July 1, 2006.

We had cash outflows from investing activities of
$212.7 million in the first six months of 2006 compared with cash outflows of $33.0 million in the first six months of 2005. The increase was primarily attributable to our investment activities in various marketable securities. As of July 1,
2006, we held marketable securities amounting to $266.7 million, which was an increase of $152.9 million from December 31, 2005 and the result of investing the proceeds from our revolver borrowings. The increase was also attributable to our
increased investment of $18.4 million in capital projects and fixed assets, of which $16.3 million was attributable to the construction of our new research and development center in Bedford, Massachusetts which is expected to be completed in 2006.
In addition, we invested $8.6 million in the acquisition of Newport Bio Systems, Inc. in April 2006.

We had cash inflows from financing
activities of $887.2 million in the first six months of 2006 as compared with cash outflows of $9.7 million in the first six months of 2005. The increase was primarily attributable to the net proceeds received from two debt offerings in advance of
our July 14, 2006 acquisition of Serologicals. Cash proceeds amounted to $565.0 million for the 3.75% convertible senior notes we issued and 250.0 million (approximately $313.8 million) for the 5.875% senior notes. These proceeds were
partially offset by debt discount of $1.2 million and payments of debt issuance and amendment costs associated with the debt offerings amounting to $19.5 million. Repayments of revolver borrowings were $21.9 million lower in 2006 than in 2005. The
increase was also attributable to $9.7 million cash received from employees upon the exercise of stock options and the $7.3 million excess tax benefits related to employee stock option exercises. Effective January 1, 2006, we adopted SFAS
No. 123(R) using the modified prospective method. This required certain related tax benefits to be included as cash inflows from financing activities that would have been included as cash inflows of operating activities under the previous
accounting rules. SFAS No. 123(R) does not allow prior period reclassification.

We maintain cash balances in many subsidiaries
through which we conduct our business. The repatriation of cash balances from certain of our subsidiaries could have adverse tax consequences; however, those balances are generally available without legal restrictions to fund ordinary business
operations. We have transferred and will continue to transfer cash from those subsidiaries to the parent and to other international subsidiaries when it is cost effective to do so.

On July 14, 2006, we paid $1.2 billion cash upon closing of the acquisition of Serologicals Corporation. We financed the acquisition with a
combination of cash on hand and net proceeds from the Convertible Notes and the Euro Notes. We expect to pay additional $277.3 million cash to holders of Serologicals convertible debentures when these holders convert their notes in or after
August 2006.

##### Table of Contents

We believe that existing sources of liquidity are adequate to meet anticipated borrowing needs at
comparable risk-based interest rates for the foreseeable future. The extent and timing of acquisition spending can cause variations in our debt to capital levels. Our level of debt to total capitalization has increased significantly to 61.6% at
July 1, 2006 as a result of funding acquisition spending. Management believes that our existing cash position and other sources of liquidity are sufficient to satisfy our various cash flow requirements, including further acquisition spending.

We continue to evaluate our tax reserves under SFAS No. 5, Accounting for Contingencies, which requires us to
accrue for losses we believe are probable and can be reasonably estimated. The amount reflected in the consolidated balance sheet at July 1, 2006 is considered adequate based on our assessment of many factors, including results of tax audits,
past experience and interpretation of tax law applied to the facts of each matter. It is reasonably possible that our tax reserves could be increased or decreased in the new term based on these factors.

Revolving credit facility

We entered
into an agreement for a five-year unsecured revolving credit facility (the Revolver) in December 2005. The acquisition of Serologicals on July 14, 2006 and the related financing required us to change certain terms of the Revolver
agreement. Accordingly, we amended the agreement in June 2006 (some of which became effective on July 14, 2006) to:



| |  |  | permit the consummation of the Serologicals acquisition and issuance and incurrence of certain additional indebtedness in connection with the acquisition;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | extend the maturity date to June 6, 2011;
| | - |  | -----------------------------------------



| |  |  | require interest rate and commitment fee adjustments based on specified credit ratings;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | require the pledge of substantially all our assets to secure our obligations under the Revolver if specified credit rating levels are reached; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | adjust certain restrictions and financial covenants.
| | - |  | ----------------------------------------------------

We
further amended the Revolver agreement in July 2006 to increase the borrowing availability under the domestic facility from 430.0 million, or $550.1 million, to 465.0 million, or $594.9 million. In the second quarter of 2006, we recorded
$2.8 million of deferred financing costs associated with amending the Revolver agreement.

We are required to pay a commitment fee ranging
between 0.0675% and 0.60% annually, based on the debt rating, on unused commitments. As of July 1, 2006, we had 64.0 million, or $81.9 million, available for borrowing on the Revolver.

We are required to maintain certain leverage and interest coverage ratios as set forth in the Revolver agreement. The agreement also includes limitations
on our ability to incur additional indebtedness, to merge, consolidate, or sell assets, to create liens, to make payments in respect of capital stock or subordinated debt, as well as other customary covenants and representations. The following table
summarizes the financial covenant requirements and our compliance with these covenants as of July 1, 2006:

Our ability to continue to comply with these covenants will depend primarily on the success in
growing our business and generating substantial operating cash flow. Future compliance with the covenants may be adversely affected by various economic, financial, and industry factors. Noncompliance with the covenants would constitute an event of
default under the Revolver, allowing the lenders to accelerate repayment of any outstanding borrowings. In the event of any potential failure by us to continue to be in compliance with any covenants, we would seek to negotiate amendments to the
applicable covenants or to obtain compliance waivers from our lenders.

As of July 1, 2006, we had borrowings of 366.0 million, or $468.2 million outstanding under
the Revolver, which were classified as long-term debt because of our intent and ability to continuously refinance them.

3.75%
convertible senior notes due 2026

In June 2006, we issued $565.0 million in aggregate principal amount of convertible senior notes (the
Convertible Notes) in a private placement offering. The Convertible Notes bear interest at 3.75% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2006.
Commencing with the six-month period beginning on December 1, 2011, if the average trading price of the Convertible Notes for the five consecutive trading days preceding such six-month periods equals 120% or more of the principal amount,
contingent interest will accrue at the rate of 0.175% of the average trading price of the Convertible Notes. The Convertible Notes are our senior unsecured obligations and rank equally with all of our existing and future senior unsecured
indebtedness. The Convertible Notes are effectively subordinated to all of our existing and future secured indebtedness and all existing and future liabilities of our subsidiaries, including trade payables. The Convertible Notes will mature on
June 1, 2026. We used the net proceeds from this offering to complete the acquisition of Serologicals on July 14, 2006. In the second quarter of 2006, we recorded $13.4 million of deferred financing costs associated with this offering.

Holders of the Convertible Notes may convert their notes into cash and, if applicable, shares of our common stock prior to June 1,
2026 under certain conditions. The Convertible Notes may be converted if the closing sale price of our common stock for each of the 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately
preceding calendar quarter exceeds 120% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter. The Convertible Notes may also be converted during the five consecutive business days immediately after
any five consecutive trading day period in which the average trading price per $1,000 principal amount of the Convertible Notes was equal to or less than 97% of the average conversion value of the notes during this period. The Convertible Notes will
also be convertible if we make certain distributions on our common stock or engage in certain transactions, if we call the Convertible Notes for redemption, and at any time from November 1, 2011 through December 1, 2011 and any time on or
after June 1, 2024. Upon conversion, the Convertible Notes will be converted into cash for the principal amount and shares of our common stock for the conversion premium, if any, based on an initial conversion rate of 11.0485 shares per $1,000
principal amount (which represents an initial conversion price of approximately $90.51 per share), subject to adjustments.

On or after
December 1, 2011, we have the option to redeem the Convertible Notes at a redemption price equal to 100% of the principal amount of the notes, plus accrued but unpaid interest. On each of December 1, 2011, June 1, 2016 and
June 1, 2021, holders of the Convertible Notes have the option to require us to purchase all or a portion of their notes at a purchase price in cash equal to 100% of the principal amount of the notes, plus accrued but unpaid interest. Holders
may also require us to repurchase all or a portion of their notes upon a fundamental change at a repurchase price in cash equal to 100% of the principal amount of the notes to be repurchased, plus accrued but unpaid interest.

A holder that surrenders the Convertible Notes for conversion in connection with a make-whole fundamental change that occurs before
December 1, 2011 may in certain circumstances be entitled to an increased conversion rate. However, in lieu of increasing the conversion rate applicable to those Convertible Notes, we may in certain circumstances elect to adjust the conversion
rate and our related conversion obligation so that the Convertible Notes will be convertible into shares of the acquiring companys common stock, except that the principal return due upon conversion will continue to be payable in cash.

The Convertible Notes were issued to qualified institutional buyers (as defined in Rule 144A under the Securities Act) in a
private placement transaction. Were required to file an effective shelf registration statement under the Securities Actwithin 180 days after issuance of the Convertible Notes for the resale of the Convertible Notes and the shares of common stock issuable upon conversion of the Convertible Notes. In the event that we fail to file an effective
registration statement, we will be required to pay additional interest equal to 0.25% per annum of the aggregate principal amount of the Convertible Notes for the 90-day period beginning on the date of the registration default and thereafter at
a rate per year equal to 0.50%. We have fulfilled this obligation by filing the required registration statement on Form S-3 on August 9, 2006.

Although we are not required to maintain any specified financial ratios under the Convertible Notes agreement, we will be considered in default if we fail to fulfill our conversion or redemption obligations, make required interest payments,
provide notice to holders of the Convertible Notes in certain specified circumstances, or cure our default on any indebtedness of ours or our subsidiaries

in the aggregate principal amount of $50 million or more. If an event of default has occurred and is continuing, the principal amount of the Convertible
Notes plus interest thereon may become immediately due and payable. We are currently in compliance with the covenant restrictions.

5.875% senior notes due 2016

In June 2006, we issued 250.0 million, or $319.8 million in aggregate principal amount
of 5.875% senior notes (the Euro Notes) due 2016. Interest is payable semi-annually in arrears on June 30 and December 30 of each year, beginning on December 30, 2006. The Euro Notes were issued at 99.611% of the principal
amount, which resulted in an original issue discount of 1.0 million, or $1.2 million. In the second quarter of 2006, we recorded $3.3 million of estimated deferred financing costs associated with the issuance of the Euro Notes. The Euro Notes
will be our senior unsecured obligations and will rank equally with all of our existing and future senior unsecured indebtedness.

If the
acquisition of Serologicals were not consummated, we would be required to repurchase the Euro Notes on or before October 31, 2006 at a redemption price, payable in cash, equal to 101% of the principal amount, plus accrued and unpaid interest. Upon
the occurrence of any change in control, holders of the Euro Notes may require us to repurchase all of their Euro Notes for a cash price equal to 101% of the principal amount, plus accrued and unpaid interest thereon. Before June 30, 2016, we
may, at our option, redeem the Euro Notes, in whole or in part, for cash, at a redemption price equal to 100% of the principal amount of the Euro Notes we redeem, plus applicable make-whole premium. In addition, we may redeem, at our
option, in whole but not in part, at a redemption price equal to 100% of the principal amount, plus accrued and unpaid interest, upon the occurrence of certain tax events in the United States.

The indenture for the Euro Notes places certain restrictions on our ability to create, incur, assume or suffer liens on our manufacturing plant and other
facilities in the United States and ability to enter into certain sales and lease-back transactions. We would also be considered in default if we fail to fulfill our redemption obligations, make required interest payments, provide notice to holders
of the Convertible Notes in certain specified circumstances, or cure our default on any indebtedness of ours or our subsidiaries in the aggregate principal amount of $50 million or more. If an event of default has occurred and is continuing, the
principal amounts of the Euro Notes plus any accrued interests thereon may become immediately due and payable. We are currently in compliance with the covenant restrictions.

While our contractual obligations and other commercial commitments did not change materially between December 31, 2005 and July 1, 2006, our
minimum future payments on our long-term debt obligations increased from $629.5 million at December 31, 2005 to $2,147.6 million at July 1, 2006. The following table summarizes our minimum future payments under our long term-debt
obligations at July 1, 2006:

Legal Matters

Millipore currently is not a party to any material legal proceeding.

Following its decision to consolidate
the results of its 40% owned Indian Joint-Venture (the India JV) in January 2006, Millipore learned as a result of its internal controls procedures that certain payment and commission practices at the India JV raise issues of compliance
with the U.S. Foreign Corrupt Practices Act. Promptly upon learning of this, Millipore through its Audit and Finance Committee engaged outside counsel and commenced an investigation, and is currently implementing certain corrective actions.
Millipore has notified the Securities and Exchange Commission and the Department of Justice of this matter. The operations and financial results of the India JV are not currently, and have not to date been, material to Millipore.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based on 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 have 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 in Item 7, beginning on page 29, in our
Annual Report on Form 10-K for the year ended December 31, 2005. 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 retirement 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



27

##### Table of Contents

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.

On January 1, 2006, we adopted Statement of Financial Accounting Standards (SFAS) No. 123 (Revised 2004), Share-Based
Payment (SFAS No. 123(R)), which required us to recognize share-based payments to employees and directors as compensation expense using a fair value-based method in the results of operations. Prior to the adoption of SFAS
No. 123(R) and as permitted by SFAS No. 123, Accounting for Stock-Based Compensation, we accounted for share-based payments to employees using the intrinsic value method pursuant to Accounting Principles Board
(APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. Therefore, no stock-based employee compensation expense had 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 time of the grant. Stock-based employee compensation expense relating to separation
agreements for certain executive officers and the vesting of restricted stock awards and restricted stock units granted at no cost to the employees was reflected in net income. Upon adoption of SFAS No. 123(R), we elected to use the modified
prospective method and, accordingly, did not restate the results of operations for the prior periods. In the three months ended July 1, 2006, compensation expense was recognized for all awards granted on or after January 1, 2006 as well as
for the unvested portion of awards granted before January 1, 2006.

Stock-based compensation expense is estimated as of the grant date
based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period. We estimate the fair value of our stock options using the Black-Scholes option-pricing model and the
fair value of our restricted stock awards and restricted stock units using the intrinsic value method. We recognize the associated compensation expense on a straight-line basis over the vesting periods of the awards, net of estimated forfeitures.
Forfeiture rates are estimated based on historical pre-vesting forfeiture history and are updated on a quarterly basis to reflect actual forfeitures of unvested awards and other known events.

Estimating the fair value for stock options requires judgment, including estimating stock-price volatility, expected term, expected dividends and
risk-free interest rates. The expected volatility rates are estimated based on historical volatilities of our common stock over a period of time that approximates the expected term of the options. The expected term represents the average time that
options are expected to be outstanding and is estimated based on the historical exercise, post-vesting cancellation and expiration patterns of our stock options. Expected dividends are estimated based on our dividend history as well as our current
projections. The risk-free interest rate for periods approximating the expected terms of the options is based on the U.S. Treasury yield curve in effect at the time of grant. These assumptions will be updated at least on an annual basis or when
there is a significant change in circumstances that could affect these assumptions.

Pursuant to requirements in SFAS No. 123(R), we
reclassified unearned compensation balance of $290 related to our restricted stock awards to additional paid-in capital as of January 1, 2006.

New Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board issued Interpretation No. 48,
Accounting for Uncertainty in Income Taxes(FIN 48). FIN 48 prescribes a more likely than not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax
return. FIN 48 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting
for income taxes in interim periods, and income tax disclosures. FIN 48 will become effective as of January 1, 2007. We are currently evaluating the impact of FIN 48 on our 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. These risks and uncertainties include, without limitation, the risk factors and uncertainties set
forth in Item 1A (Risk Factors) and elsewhere in our Form 10-K for the year ended December 31, 2005 and the risk factors set forth in Part II, Item 1A (Risk Factors) of this Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

The information called for by this
item is set forth under the heading Market Risk in Managements Discussion and Analysis contained in this Form 10-Q which information is hereby incorporated by reference.

Item 4. Controls and Procedures.

An evaluation was carried out under the supervision and with the
participation of our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under
the Securities Exchange Act of 1934 (the Exchange Act)) as of the end of the fiscal quarter covered by this report. Based upon that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures are effective.
There has been no change in our internal control over financial reporting during the quarter ended July 1, 2006 that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.

PART II

Item 1A. Risk Factors

We completed our acquisition of Serologicals Corporation (Serologicals) on
July 14, 2006. In order to finance the acquisition, we incurred substantial additional debt, including the issuance of notes convertible into our common stock. As a result of the acquisition, certain risks associated with Serologicals are now
risks to the combined company. The following risks relate to our borrowings to finance the acquisition and our conduct of the Serologicals business after the acquisition:

Increased leverage as a result of our recent debt offerings and other debt we have incurred to finance our acquisition of Serologicals may harm our financial condition and results of operations.

As of July 1, 2006, our total debt was $1,451.8 million. Of this amount, $100.0 million is due under our 7.5% senior unsecured notes in 2007 and approximately $468.2
million (366.0 million) represents indebtedness of our subsidiaries under our revolving credit facilities that is guaranteed by us. We established our revolving credit facilities in December 2005 against which we can borrow in either the
United States or Europe, with a combined maximum borrowing not to exceed 465.0 million (giving effect to amendments that became effective on July 14, 2006). As of July 1, 2006, on a pro forma basis, assuming we had completed the
acquisition of Serologicals, we would have had $1,729.1 million of total debt. This amount includes approximately $130.0 million of outstanding convertible debentures originally issued by Serologicals, which are convertible into an aggregate of
approximately $277.3 million in cash. We expect such convertible debentures will be converted by the holders thereof at some point in the near future.

Our
level of indebtedness could have important consequences to you, because:



| |  |  | a substantial portion of our cash flows from operations will have to be dedicated to interest and principal payments and may not be available for operations, working capital,
capital expenditures, expansion, acquisitions or general corporate or other purposes;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | it may impair our ability to obtain additional or replacement financing in the future;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | it may limit our flexibility in planning for, or reacting to, changes in our business and industry; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | it may make us more vulnerable to downturns in our business, our industry or the economy in general.
| | - |  | ----------------------------------------------------------------------------------------------------

Our operations may not generate sufficient cash to enable us to service our debt. If we fail to make a payment on any of our debt obligations, we could be in default on such debts, and this default could cause us to
be in default on our other outstanding indebtedness.

Future issuances of common stock may depress the trading price of our common stock and our convertible notes.

Any issuance of equity securities, including the issuance of shares upon conversion of our convertible notes, could dilute the interests of our
existing stockholders, including holders who have received shares upon conversion of their notes, and could substantially decrease the trading price of our common stock and our convertible notes. We may issue equity securities in the future for a
number of reasons, including to finance our operations and business strategy (including in connection with acquisitions, strategic collaborations or other transactions), to adjust our ratio of debt to equity, to satisfy our obligations upon the
exercise of outstanding warrants or options or for other reasons.

Concern about the transmission of mad-cow disease could reduce the demand
for Serologicals cell culture products that are derived from bovine serum.

The demand for several of Serologicals cell culture products
could be adversely affected by concerns about some of their components being derived from bovine serum. The demand for some of Serologicals products could be adversely affected by concerns about the use of bovine material in the process by
which it is manufactured. The concern arises from the risk that the agent causing bovine spongiform encephalopathy, or mad-cow disease, might be present in the raw materials used in the production process and that the agent might be
introduced into a therapeutic substance manufactured by one of our customers. The regulatory authorities of certain countries, including Japan, have refused to approve pharmaceuticals that are manufactured using a product that was derived from
bovine serum or that was manufactured by a process that uses bovine material. The regulatory authorities of other countries could adopt similar restrictions.

Violation of government regulations or voluntary quality programs could result in loss of Serologicals sales and customers and additional expense to attain compliance.

Several of Serologicals facilities are subject to extensive regulation by the United States Food and Drug Administration (FDA), primarily through the
requirements of the Public Health Service Act and the Food, Drug and Cosmetic Act, and similar governmental bodies in other countries. The Serologicals facilities are subject to periodic inspection by the FDA and other similar governmental bodies to
ensure their compliance with applicable laws and regulations. New facilities, products and operating procedures also may require approval by the FDA and/or similar governmental bodies in other countries. Failure to comply with these laws and
regulations could lead to sanctions by the governmental bodies, such as written observations of deficiencies made following inspections, warning letters, product recalls, fines, product seizures and consent decrees, which would be made available to
the public. Such actions and publicity could affect our ability to sell products and to provide our services acquired from Serologicals. In the past, Serologicals received notifications and warning letters from the FDA relating to deficiencies in
its compliance with FDA requirements and was required to take measures to respond to the deficiencies. There can be no assurance that the FDA will not request that we take additional steps to correct these deficiencies or other deficiencies in
compliance raised by the FDA in the future. Correction of any such deficiencies could have a material adverse affect on our business.

The Serologicals
operations are also subject to USDA regulations and various foreign regulations for the sourcing, manufacturing and distribution of animal based proteins, all of which now apply to us as a result of the acquisition. Our failure to comply with these
requirements could negatively impact our business and potentially cause the loss of Serologicals customers and sales. ISO 9000:2000 quality standards are an internationally recognized set of voluntary quality standards that require compliance with a
variety of quality requirements somewhat similar to the requirements of the FDAs Quality System Regulations, which were formerly known as Good Manufacturing Practices or GMP. The operations of Serologicals cell culture manufacturing
facilities, as well as its manufacturing facility in Scotland and its research products facilities in California, Australia and the United Kingdom, are registered under the ISO standards. Failure to comply with this voluntary standard can lead to
observations of non-compliance or even suspension of ISO certification by the certifying unit. Loss of ISO certification could cause some Serologicals customers to purchase products from other suppliers.

If we are not able to identify new licensing opportunities or to enter into licenses for new products on acceptable terms to support the Serologicals business, we may
be unable to leverage new products in that market segment, which could adversely affect our anticipated earnings.

An important component of
Serologicals business strategy is to increase the number of products it offers by licensing products developed by other biotechnology companies or academic research laboratories. It has historically attempted to market such products to its
customers. Often, it sought to improve the licensed products using its technologies. Therefore, our Serologicals business will depend on the success of our licensing efforts for a portion of our new products. There can be no assurance that our
licensing efforts will be successful.

##### Table of Contents

Serologicals licenses technology that enables it to access proprietary biological materials that it uses to manufacture
its products. Some of the licenses do not provide guarantees that it will have all legal rights to sell products that are derived from the licensed technology. Therefore, we may be prevented from selling Serologicals products produced with the
licensed biological materials because of competing technologies owned by others, including patented technologies. If the Serologicals products are found by a court to infringe intellectual property rights of a third party, we may be prevented from
practicing that technology. Moreover, if found by a court to infringe the patent of the third party, we may be liable for compensatory damages, treble damages and attorneys fees and subject to a royalty obligation or enjoined from practicing
the technology altogether, notwithstanding the license from the licensor. We have no assurance that we will not incur material liability as a result of an infringement claim in the future, which could materially adversely affect our results of
operations.
