Notes to Condensed Consolidated Financial Statements

(In thousands, except per share data) (Unaudited)

1.  GENERAL

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, 2009 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 our 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 our operations for the entire year. These financial statements should be read
in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2009.

Our interim fiscal quarters end 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 first fiscal quarters of 2010 and 2009 ended on April 3, 2010 and April 4, 2009, respectively.

In
June 2009, the Financial Accounting Standards Board (the FASB) issued an amendment to the accounting and disclosure requirements for the consolidation of variable interest entities (VIE) and the evaluation of when
consolidation of a VIE is required, which we adopted as of January 1, 2010. The amendment did not have an effect on our consolidated financial statements.

2.  PROPOSED TRANSACTION WITH MERCK KGaA

On February 28, 2010, we entered into a definitive agreement under which Concord Investments Corp., a fully owned subsidiary of Merck KGaA, will acquire all
outstanding shares of our common stock for $107 per share in cash. This business combination will create a world-class partner for the Life Science sector with significant businesses in high-margin specialty products and an attractive growth
profile.

Through the date of this filing, Millipore announced key milestones relating to the proposed transaction, including: the transaction was
approved by the boards of directors of both companies; the waiting period required under the Hart-Scott-Rodino Antitrust Improvements Act expired; the Special Shareholders Meeting to vote on the proposed transaction will take place on
June 3, 2010; and the Company filed its definitive proxy with the Securities and Exchange Commission. The proposed transaction is expected to be completed in the early part of the third quarter of 2010.

During the three months ended April 3, 2010, we recorded $2,346 of costs consisting primarily of legal and regulatory fees associated with this proposed
transaction in our condensed consolidated statement of operations as selling, general and administrative expenses.

Our revenues from Merck KGaA as a
customer were not material for the three months ended April 3, 2010 and April 4, 2009, respectively.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)

(In thousands, except per share data) (Unaudited)



For the three months ended April 3, 2010 and April 4, 2009, outstanding stock options and restricted stock units amounting to 195 and 1,281,
respectively, were excluded from the calculation of diluted earnings per share because of their antidilutive effect. Performance-based restricted stock units were excluded from the calculation of diluted earnings per share because they are
considered contingently issuable shares and the underlying targeted financial metrics have not been achieved.

The proposed acquisition by Merck KGaA
resulted in an increase in our stock price during the three months ended April 3, 2010, which caused shares issuable for the conversion premium upon conversion of our $565,000 3.75 percent convertible senior notes (the Convertible
Notes) to be dilutive to earnings as of April 3, 2010. Shares issuable for the conversion premium on the Convertible Notes were excluded from diluted earnings per share for the three months ended April 4, 2009 because our stock price
had not exceeded the conversion price.

At April 3, 2010, we had
465,000, or $627,615, available for borrowing under our primary revolving credit agreement (the Revolver). The Revolver
expires in June 2011. At April 3, 2010, we were in compliance with all financial covenants under the Revolver.

As of April 3, 2010, our
Convertible Notes had a fair value of $709,781 and our 5.875 percent senior notes had a fair value of $371,170. Fair value was determined from available market prices using current interest rates, non-performance risk, and term to maturity.

The following table sets forth balance sheet information regarding the Convertible Notes:

10.  INCOME TAXES

Our effective tax rate
was 23 percent for the three months ended April 3, 2010 versus 18 percent for the prior year comparable period. Our effective tax rate for the prior year comparable period was lower because of the $8,542 non-taxable gain on the Guava
acquisition. The higher current year rate was also attributable to a shift in the jurisdictional mix of our profits to higher tax rate jurisdictions this year and $1.5 million U.S. R&D credits recognized in the prior year comparable period. The
R&D credit provisions expired at the end of fiscal year 2009, which resulted in a higher effective tax rate for the current period.

12.  DERIVATIVE INSTRUMENTS AND
HEDGING

The purpose of our hedging activities is to mitigate the impact of volatility associated with foreign currency transactions and interest rate
exposures related to an anticipated debt refinancing. We do not hold derivative instruments for trading or speculative purposes.

Cash
Flow Hedges

We utilize foreign currency forward exchange contracts to hedge anticipated intercompany sales transactions in certain foreign currencies
and designate these derivative instruments as cash flow hedges when appropriate. We enter into forward exchange contracts that match the currency, timing, and notional amounts of the underlying forecasted transactions. Therefore, no ineffectiveness
resulted, or was recorded, through the consolidated statement of operations in any of the periods

presented. Our forward exchange contracts are primarily short term in nature with maximum contract durations of fifteen months. At April 3, 2010, these forward exchange contracts had
aggregate U.S. dollar equivalent notional amounts of $303,347 and aggregate U.S. dollar equivalent fair values amounting to a net gain of $2,646. The net gain or loss from these cash flow hedges reported in accumulated other comprehensive income
will be reclassified to earnings and recorded in revenues in our consolidated statement of operations when the related inventory is sold to third-party customers. The amounts ultimately recognized will vary based on fluctuations of the hedged
currencies through the contract maturity dates. At April 3, 2010, we had $211 in net realized losses in accumulated other comprehensive income which will be recognized as a reduction to revenues in the 2010 second quarter.

In August 2009, we entered into forward starting interest rate swap agreements with an aggregate notional amount of $300 million. The purpose of these swaps is to
hedge interest rate exposures related to an anticipated fixed-rate debt financing in December 2011 with a term of at least 10 years. On April 2, 2010, the interest rate swaps were settled, which resulted in a gain of $2,277, net of tax of
$1,423, that was recorded in accumulated other comprehensive income. This gain will be recognized in earnings as an adjustment to interest expense in our consolidated statement of operations in the same period that the hedged interest payments are
recorded in our statement of operations or when the probability that the anticipated fixed-rate debt financing will occur is remote.

Net Investment Hedge

We designated our 5.875
percent senior notes, which are denominated in Euro, as a hedge of the foreign currency exposures of our net investment in a European subsidiary. Foreign exchange gains or losses on the hedge, which are caused by the remeasurement of the Euro debt
to U.S. dollars, are recorded in other comprehensive income as a component of cumulative translation adjustment. At April 3, 2010 and December 31, 2009, the cumulative net loss on these senior notes included in accumulated other
comprehensive income was $23,647 and $44,181, respectively.

Embedded Derivatives

The contingent interest feature of the Convertible Notes represents an embedded derivative that requires separate recognition at fair value apart from the
Convertible Notes. As a result, we are required to separate the value of this feature from the Convertible Notes and record a liability on the condensed consolidated balance sheet. At April 3, 2010 and December 31, 2009, the contingent
interest feature had no value.

Other Derivatives

In addition to cash flow hedges and the net investment hedge, we also enter into foreign currency forward exchange contracts to mitigate the impact of foreign
exchange risk related to foreign currency denominated intercompany debt and foreign currency receivable and payable balances. Both realized and unrealized gains and losses resulting from changes in the fair value of these derivative instruments are
recorded through current earnings because we do not designate these forward exchange contracts as hedges. The aggregate U.S. dollar equivalent notional amount of these forward exchange contracts was $253,549 at April 3, 2010. Cash paid or
received upon settlement of these forward exchange contracts is included in operating activities in the condensed consolidated statements of cash flows.

13.  FAIR VALUE MEASUREMENTS

We hold cash equivalents, derivatives, certain other assets, and certain other liabilities that are carried at fair value. We generally determine fair
value using a market approach based on quoted prices of identical instruments, when available. When market quotes of identical instruments are not readily accessible or available, we determine fair value based on quoted market prices of similar
instruments. Nonperformance risk of counter-parties is considered in determining the fair value of derivative instruments in an asset position while the impact of our own credit standing is considered in determining the fair value of our
obligations.

14. COSTS ASSOCIATED WITH EXIT ACTIVITIES

On September 10, 2008, we took actions to optimize the performance of our global supply chain and reduce our cost structure to improve operational efficiency.
These actions were partly in response to the market conditions that caused revenue declines in our Bioprocess Division in 2008. These actions were also part of our long term strategy to further improve the

efficiency of our global supply chain, primarily through consolidation of our manufacturing locations. We have substantially completed this program as of April 3, 2010. We expect to complete
this program in 2010 with the closing of one more facility and do not anticipate significant additional charges relating to this program going forward.

The following table summarizes expected, incurred, and remaining costs associated with these actions at April 3, 2010:

During the three months ended April 3, 2010, we
recorded costs associated with these exit activities in our condensed consolidated statement of operations of $612, $14, and $2 in cost of revenues, selling, general and administrative expenses and research and development expenses, respectively.

15.  NONCONTROLLING INTEREST

On November 20, 2009, we acquired the remaining 60% ownership of our joint venture in India (the India JV) for $58,082 in cash. Prior to
November 20, 2009, we owned a 40% equity interest in our India JV which we consolidated as we determined that substantially all of the activities of the India JV involved us or were conducted on our behalf.

16.  CONTINGENCIES

The proposed
acquisition by Merck KGaA resulted in two putative shareholder class actions challenging the exchange have been filed in Massachusetts naming Millipore, Merck, Sub and certain officers and directors of Millipore as defendants. The first such case is
Elliot v. Millipore Corporation, et al., No. 10-0853 (filed March 2, 2010) (Elliot), and the second such case is United Union of Roofers, Waterproofers and Allied Workers Local Union No. 8 v. Millipore Corporation et al.,
No. 10-0855 (filed March 4, 2010) (United Union of Roofers). The complaints, which are similar, allege claims for breach of fiduciary duty against the individual defendants and for aiding and abetting a breach of fiduciary duty
against the

corporate defendants. The complaints seek equitable relief including an order enjoining the exchange. The complaints generally allege that the consideration offered in the proposed transaction is
inadequate and the process through which the proposed transaction was approved was unfair. The plaintiff in United Union of Roofers has notified the Elliot parties that it intends to seek consolidation of the two actions. Millipore is defending the
lawsuit and along with the other defendants served a motion to dismiss Elliot on April 26, 2010.

We are also subject to a number of claims and
legal proceedings which, in the opinion of our management, are incidental to our normal business operations. In our opinion, although final settlement of these suits and claims may impact our financial statements in a particular period, they are not
expected to, in the aggregate, have a material adverse effect on our financial position, cash flows or results of operations.

17.  RECENT ACCOUNTING PRONOUNCEMENTS

In
October 2009, the Emerging Issues Task Force (the EITF) reached consensus on an amendment to the accounting and disclosure requirements for revenue arrangements with multiple deliverables. The amendment eliminates the use of the residual
method of allocation and requires, instead, that arrangement consideration be allocated, at the inception of the arrangement, to all deliverables based on their relative selling price. When applying the relative selling price allocation method, the
selling price for each of the deliverables shall be determined using vendor-specific objective evidence (VSOE), if it exists, otherwise third-party evidence (TPE). If neither VSOE nor TPE exists, the amendment allows a vendor
to use its best estimate of selling price. This amendment is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Alternatively, this amendment may be applied
retrospectively to all periods presented. Earlier application is permitted as of the beginning of an entitys fiscal year. We plan to adopt this amendment as of January 1, 2011 and do not believe this amendment will have a material effect
on our consolidated financial statements.

ITEM 2.MANAGEMENTS DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS



Basis of Presentation

The following
Managements Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our Condensed Consolidated Financial Statements and related notes thereto and other financial information included
elsewhere in this Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2009. We will also be disclosing certain non-GAAP information in the Managements Discussion and Analysis. A reconciliation of our GAAP
financial measures to our non-GAAP financial measures and information about the use of non-GAAP measures begins on page 28 under the heading Use of Non-GAAP Financial Measures.

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 first fiscal quarters of 2010 and 2009 ended on April 3, 2010 and April 4, 2009, respectively.

PROPOSED TRANSACTION WITH MERCK KGaA

On
February 28, 2010, we entered into a definitive agreement under which Concord Investments Corp., a fully owned subsidiary of Merck KGaA, will acquire all outstanding shares of our common stock for $107 per share in cash. This business
combination will create a world-class partner for the Life Science sector with significant businesses in high-margin specialty products and an attractive growth profile.

Through the date of this filing, Millipore announced key milestones relating to the proposed transaction, including: the transaction was approved by the boards of
directors of both companies; the waiting period required under the Hart-Scott-Rodino Antitrust Improvements Act expired; the Special Shareholders Meeting to vote on the proposed transaction will take place on June 3, 2010; and the Company
filed its definitive proxy with the Securities and Exchange Commission. The proposed transaction is expected to be completed in the early part of the third quarter of 2010.

Consolidated revenues of $463.0 million for the
three months ended April 3, 2010 increased $55.1 million, or 14 percent, versus the prior year comparable period. Adjusting for a 5 percentage point favorable effect from foreign currency translation, our consolidated revenues for the three
months ended April 3, 2010 grew 9 percent. We delivered strong revenue growth as we benefited from the contribution of new products and a strengthening economic environment. Our results were well-balanced between both divisions. From a
geographic perspective, we generated double-digit revenue growth in North America and Asia. Our Bioscience Division revenue growth was attributable to higher laboratory instrumentation sales and increased demand from pharmaceutical customers, two
areas which rebounded from last year. Bioprocess Division revenue growth was primarily the result of continued higher spending by our biotechnology customers.

PART I



Operating profit increased to $88.1 million for the three months ended April 3, 2010 from $71.3 million in the prior year comparable period. Higher
revenues, favorable impact from changes in foreign currency exchange rates, and lower costs related to the global supply chain initiatives were the primary drivers of the increase. This profit expansion enabled us to continue to invest in research
and development in accordance with our innovation strategy and absorb the effects of an unfavorable product mix and higher employee-related costs. Our gross margin increased to 56 percent for the three months ended April 3, 2010 from 55 percent
in the prior year comparable period.

Diluted GAAP and non-GAAP earnings per share (EPS) were $0.99 and $1.21, respectively, for the three
months ended April 3, 2010 and increased by $0.04 and $0.15, respectively, versus the prior year comparable period. (Please see our non-GAAP reconciliation which begins on page 28.) Higher operating profit contributed to higher GAAP EPS,
which was offset by a higher tax rate in the current period and the absence this year of the $8.5 million non-taxable gain resulting from our Guava business acquisition. Diluted EPS was also adversely impacted by shares issuable upon conversion of
the 3.75 percent convertible notes becoming dilutive as a result of the increase in our stock price during the three months ended April 3, 2010 and an increase in dilution of stock-based compensation awards.

Free cash flow is an important operating metric that we define as net cash provided by operating activities less additions to property, plant and equipment. We
generated $76.7 million of free cash flow for the three months ended April 3, 2010, a 12 percent increase over the prior year comparable period. This growth was primarily attributable to a significant improvement in our inventory management as
a result of our working capital initiatives. Over the past year, we have lowered our days of inventory outstanding from 129 days at April 4, 2009 to 109 days at April 3, 2010.

Bioprocess Division

Bioprocess revenues of $258.3 million for the three months ended April 3, 2010 increased $28.3 million, or 12 percent, versus the prior year comparable period.
Excluding the favorable effect of foreign currency translation, Bioprocess revenues increased 9 percent. The revenue growth was primarily attributable to higher sales of our downstream bioprocessing products used in biopharmaceutical manufacturing,
which was a result of the following: higher spending levels by our North America biotechnology customers as these customers are accelerating their production of monoclonal antibodies; increased revenues related to disposable manufacturing as
companies continue to migrate to single use, disposable technologies that eliminate the need for cleaning and sterilization, thus shortening the time between processing runs; and higher revenues in Asia, particularly in China and Singapore, due to
biotechnology industry growth in the region and more stringent regulatory compliance standards in China.

To a lesser extent, the Bioprocess revenue increase was the result of continued growth in process monitoring tools products. Demand for on-site
testing products, particularly our disposable NovaSeptum® products, continued to increase, as drug companies are adopting
disposable sampling technology to monitor contamination earlier in the drug manufacturing process.

Bioscience Division

Bioscience revenues of $204.7 million for the three months ended April 3, 2010 increased $26.8 million, or 15 percent, versus the prior year comparable period.
Excluding the favorable effect of foreign currency translation, Bioscience revenues increased 9 percent. The divisions revenue growth benefited from increased spending from pharmaceutical customers and higher sales of laboratory
instrumentation products. These two areas were weak last year and benefited from an improving economic environment in the three months ended April 3, 2010, particularly in North America and Asia. Bioscience revenue growth was also attributable
to successful new product launches and a $3.3 million revenue from a technology license.

From a geographic perspective, reported revenues
increased in all regions, $23.7 million in the Americas, $3.8 million in Europe, and $27.6 million in Asia/Pacific, during the three months ended April 3, 2010 versus the prior year comparable period. Excluding the effects of foreign currency
translation, revenues increased 14 percent in the Americas, decreased 5 percent in Europe, and increased 28 percent in Asia/Pacific. The increase in the Americas was primarily the result of higher spending by our Bioprocess biotechnology customers
and Bioscience pharmaceutical customers as well as the $3.3 million revenue from a technology license. The decrease in Europe was primarily attributable to general economic conditions and the timing of purchases by certain larger Bioprocess
customers. The increase in Asia/Pacific was primarily driven by revenue growth in our downstream bioprocessing products in China and Singapore and higher Bioscience revenues in Japan as the economy began to improve.

|Gross profit margin |  |                    | 56    | % |              |   | 55    | %

Gross profit increased $36.1 million, or 16 percent, versus the
prior year comparable period. Gross profit margin improved from 55 percent of revenues last year to 56 percent of revenues this year. The primary drivers of the increase in gross profit margin were favorable foreign currency, a decrease in inventory
write-offs due to our working capital improvement actions implemented last year, lower costs associated with our global supply chain initiatives, and a slight impact from price increases. The favorable foreign currency impact was primarily the
result of a weaker U.S. dollar, versus the prior year comparable period. Generally, when the Japanese Yen strengthens against the U.S. dollar and Euro, our gross profit margin is favorably impacted because substantially all of our manufacturing
activities are in the United States, Ireland, and France. We incurred charges associated with our global supply chain initiatives amounting to $0.6 million and $3.3 million in the three months ended April 3, 2010 and April 4, 2009,
respectively. By the end of fiscal year 2010, we expect to complete these initiatives by incurring approximately $1.5 million of planned additional costs.

These favorable effects were partly offset by an unfavorable product mix in our upstream bioprocessing products and, to a lesser extent, higher salary and facility
costs.

Selling, general and administrative (SG&A)
expenses increased $14.3 million, or 11 percent, versus the prior year comparable period. Excluding the adverse effect of foreign currency translation, SG&A expenses increased $10.2 million, or 8 percent. The increase was primarily attributable
to increased employee-related costs driven by: salary increases; higher incentive compensation costs; and higher costs related to our non-employee director deferred compensation plan resulting from an increase in the Millipore stock price.
Additionally, acquisition and related integration expenses increased due to the proposed acquisition by Merck KGaA. Amortization expense for the three months ended April 3, 2010 affecting SG&A was $11.5 million versus $12.0 million in the
prior year comparable period.

Research and development (R&D) expenses increased $4.9 million, or 19 percent, versus the prior year comparable period. Excluding the adverse effect
of foreign currency translation, R&D expenses increased $4.5 million, or 18 percent. The increase was primarily attributable to increased employee-related costs driven by salary increases, higher incentive compensation costs, and increased
headcount. Additionally, technology partner payments have increased as a result of our strategy to enhance our internal R&D capabilities through technology collaborations and license arrangements with third parties. We expect 2010 full year
R&D expenses to be approximately 7 percent of revenues.

Interest expense decreased $0.3 million, or 2 percent, versus
the prior year comparable period. Excluding the adverse effect of foreign currency translation, interest expense decreased $0.5 million, or 3 percent. The decrease was the result of lower overall debt balances.

|Effective income tax rate |  | 23                 | % |  | 18           | %

Our effective tax rate was 23 percent for the three
months ended April 3, 2010 versus 18 percent for the prior year comparable period. Our effective tax rate for the prior year comparable period was lower because of the $8.5 million non-taxable gain on the Guava acquisition. The higher current
year rate was also attributable to a shift in the jurisdictional mix of our profits to higher tax rate jurisdictions this year and $1.5 million U.S. R&D credits recognized in the prior year comparable period. The R&D credit provisions
expired in December 2009, thus resulting in a higher effective tax rate for the current period. On a full year basis, we expect our effective tax rate to be approximately 22 percent.

Over the next twelve months, we may need to record up to $3,900 of previously unrecognized tax benefits in the event of statute of limitations closures and
settlements of tax audits.

Operating profit increased $16.8 million, or 23.6 percent, versus the prior comparable period, primarily as a result of higher revenues and favorable effect of
foreign currency translation. These increases were partially offset by higher employee-related costs and higher investments in research and development. On a GAAP basis, the 8 percent increase in net income attributable to Millipore was the result
of higher operating profit which was partially offset by a higher tax rate in the current period and the absence this year of the $8.5 million non-taxable gain on the Guava acquisition. On a non-GAAP basis, the 19 percent increase in net income
attributable to Millipore was the result of higher operating profit.

We assess our liquidity
in terms of our ability to generate cash to fund our operating, investing, and financing activities. 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 acquisitions, deterioration in certain financial ratios, and market changes in general.

The cost of additional or replacement financing is partly a function of our debt to capitalization levels, credit standing, and financial market conditions. Our
credit ratings are reviewed regularly by major debt rating agencies such as Standard & Poors and Moodys Investors Service. The chart below summarizes our ratings at April 3, 2010.

We believe our
future operating cash flows will be sufficient to meet our future operating and investing cash needs. The availability of borrowings under our primary revolving credit facility and our ability to obtain equity financing provide additional potential
sources of liquidity should they be required. We intend to utilize excess cash generated from our operations to fund future acquisitions while preserving an appropriate level of cash needed for our operations. We may from time to time seek to retire
or purchase our outstanding obligations. We may also seek to repurchase shares of our common stock. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions, and other
factors.

In August 2009, we entered into forward starting interest rate swap agreements with an aggregate notional amount of $300.0 million. The purpose
of these swaps is to hedge interest rate exposures related to an anticipated fixed-rate debt financing in December 2011 with a term of at least 10 years. On April 2, 2010, the interest rate swaps were settled, resulting in a gain of $2.3
million, net of tax of $1.4 million, which was recorded in accumulated other comprehensive income. This gain will be recognized in earnings as an adjustment to interest expense in our consolidated statement of operations in the same period when the
hedged interest payments are recorded in our statement of operations or when the probability that the anticipated fixed-rate debt financing will occur is remote.

OPERATING CASH FLOWS

Cash provided by operating
activities was $88.3 million for the three months ended April 3, 2010 and was primarily attributable to our net income of $57.2 million, non-cash items totaling $38.7 million (primarily depreciation and amortization expenses, stock-based
compensation expense, and debt discount amortization), and a net working capital increase of $7.7 million. Our working capital increase was primarily the result of an increase in accounts receivable and a decrease in

accrued expenses offset by decrease in inventory and increases in accounts payable and income taxes payable balances. The increase in accounts receivable since year end was primarily attributable
to the higher overall revenues as well as timing of our sales during the quarter. Days sales outstanding was 63 days at April 3, 2010, compared to 59 days at December 31, 2009 and 67 days at April 4, 2009. The decrease in accrued
expenses since year end was primarily attributable to payments made to employees under the 2009 management incentive plan paid during the three months ended April 3, 2010. The decrease in inventory was attributable to two main factors. First,
continued global supply chain initiatives contributed to reductions in inventory levels. Secondly, the timing of product sales as well as overall revenue increases helped reduce inventory levels. Days of inventory was 109 days at April 3, 2010,
compared to 118 days at December 31, 2009 and 129 days at April 4, 2009. At the end of 2009, we accelerated cash payments to take advantage of early vendor payment discounts, which decreased our December 31, 2009 accounts payable
balance. For the three months ended April 3, 2010, the amount of early payment discount opportunities decreased causing accounts payable to increase as of April 3, 2010. Lastly, the increase in income taxes payable was attributable to an
increase in profitability in higher tax rate jurisdictions.

INVESTING CASH FLOWS

Cash used for investing activities was $12.3 million during the three months ended April 3, 2010. We paid $11.6 million for capital expenditures and expect our
full year 2010 capital expenditures to be approximately $80 million.

FINANCING CASH FLOWS

Cash used for financing activities was $15.4 million during the three months ended April 3, 2010 resulting from net repayments of short-term debt of $32.3
million, which was offset by proceeds of $16.9 million from exercises of employee stock options. Increases in stock option exercises were attributable to the higher stock price as a result of the proposed Merck KGaA transaction.

FINANCING COMMITMENTS

Short-term
debt

Short-term debt consisted of borrowings under our operating bank facilities and two short-term revolving credit facilities in Japan. These two
credit facilities provide for cumulative borrowings of ¥7.0 billion, or $74.0 million, with an interest rate of TIBOR plus an applicable margin. Interest is payable at the end of an interest period based upon the term of the borrowing. These
credit facilities expire in December 2010 and are subject to automatic annual renewals subject to termination by either Millipore or the banks. As of April 3, 2010, we had ¥6.0 billion, or $63.3 million, available for borrowing under these
credit facilities. We are not required to comply with any debt covenants under these agreements.

Primary revolving credit facility

At April 3, 2010, we had a commitment under our primary revolving credit agreement amounting to
465.0 million, or $627.6 million. This credit agreement expires in June 2011.

We are required to maintain certain leverage and interest coverage ratios set forth in the primary revolving credit agreement. As of April 3, 2010, we were
compliant with all financial covenants specified in this credit agreement. The agreement also includes limitations on our 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.

The following table summarizes the financial covenant requirements and our compliance with these covenants as of April 3, 2010:

|Minimum interest coverage ratio |  | 3.50        |  | 10.22                 

As of April 3, 2010, we had no borrowings under our
primary revolving credit facility.

3.75% convertible senior notes due 2026

In June 2006, we issued $565.0 million in aggregate principal amount of 3.75 percent convertible senior notes (the Convertible Notes) in a private
placement offering. The estimated fair value of a similar debt instrument without the conversion feature was $483.7 million at the time of issuance. The resulting $81.3 million discount on the debt is being amortized through interest expense over
the period from June 2006 through December 2011, which represents the expected life of the debt. As a result, our Convertible Notes have a 6.94 percent effective interest rate.

As of April 3, 2010, the Convertible Notes had a carrying value of $537.1 million, net of $27.9 million of unamortized discount, and a fair value of $709.8
million. The fair value was determined from available market prices using current interest rates, non-performance risk, and term to maturity.

5.875% senior notes due 2016

In June 2006, we
issued 250.0 million, or $337.4 million, in aggregate principal amount of 5.875 percent senior notes (the Euro Notes).

As of April 3, 2010, the Euro Notes had a carrying value of $336.6 million, net of $0.8 million of unamortized original issue discount, and a fair
value of $371.2 million. This fair value was determined from available market prices using current interest rates, non-performance risk, and term to maturity.

Legal Matters

The proposed acquisition by Merck
KGaA resulted in two putative shareholder class actions challenging the exchange have been filed in Massachusetts naming Millipore, Merck, Sub and certain officers and directors of Millipore as defendants. The first such case is Elliot v. Millipore
Corporation, et al., No. 10-0853 (filed March 2, 2010) (Elliot), and the second such case is United Union of Roofers, Waterproofers and Allied Workers Local Union No. 8 v. Millipore Corporation et al., No. 10-0855
(filed March 4, 2010) (United Union of Roofers). The complaints, which are similar, allege claims for breach of fiduciary duty against the individual defendants and for aiding and abetting a breach of fiduciary duty against the
corporate defendants. The complaints seek equitable relief including an order enjoining the exchange. The complaints generally allege that the consideration offered in the proposed transaction is inadequate and the process through which the proposed
transaction was approved was unfair. The plaintiff in United Union of Roofers has notified the Elliot parties that it intends to seek consolidation of the two actions. Millipore is defending the lawsuit and along with the other defendants served a
motion to dismiss Elliot on April 26, 2010.

PART I



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 55, of our Annual Report on Form 10-K for the year ended December 31, 2009. Those policies and estimates were identified as those relating to revenue recognition,
inventory valuation, valuation of long-lived assets, stock-based compensation, income taxes, and employee retirement plans. We continue to evaluate our estimates and judgments on an on-going basis. By their nature, these estimates and judgments are
subject to an inherent degree of uncertainty. We base our estimates and judgments on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ materially from these
estimates under different assumptions or conditions.

New Accounting Pronouncements

For a description of recent accounting pronouncements, see Note 17 Recent Accounting Pronouncements in the Notes to condensed consolidated financial
statements in this Form 10-Q.

Use of Non-GAAP Financial Measures

Millipore provides non-GAAP supplemental information to its financial results. Non-GAAP net income attributable to Millipore and diluted earnings per share exclude
costs related to global supply chain initiatives, acquisition and related integration expenses, costs related to the proposed acquisition, amortization of purchased intangible assets, inventory fair value adjustments related to business
acquisitions, gain on business acquisition, and non-cash interest expense on our Convertible Notes. We define free cash flow as net cash provided by operating activities less additions to property, plant, and equipment. We define net debt as our
debt less cash and cash equivalents.

We believe that the non-GAAP financial measures provide useful and supplementary information to investors regarding
our operating performance, although they may not be directly comparable to measures used by other companies. It is our belief that these non-GAAP financial measures have been particularly useful to investors over the last few years because of the
significant changes that have occurred outside of our day-to-day business in accordance with the execution of our strategy. Non-GAAP information should not be construed as an alternative to GAAP information as the items excluded from the non-GAAP
measures often have a material impact on our financial results. Management uses, and investors should use, non-GAAP measures in conjunction with our GAAP results.

|(1) |  | We exclude severance and relocation costs, facility closure costs, and accelerated depreciation associated with our global supply chain initiatives because they are material
expenses in excess of our normal operating costs. We undertook these initiatives to significantly reduce our cost structure and improve operational efficiency primarily through the consolidation of manufacturing locations.

|(2) |  | We exclude the amortization of purchased intangible assets, gain on business acquisition, and inventory fair value adjustments from business acquisitions because (i) the
amounts are non-cash, (ii) we can not influence the timing and amount of future expense recognition, and (iii) excluding such expenses provides investors and management better visibility into the components of operating expenses.
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) |  | We exclude costs related to the proposed acquisition and acquisition and related integration expenses to make year-over-year comparisons because these are incremental costs to
our day-to-day business and can be material.
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) |  | Non-cash interest expense on our Convertible Notes is the incremental interest expense as a result of a change in accounting principles. This interest expense is non-cash and we
can not control the amount of this expense without modifying our capital structure.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
MARKET RISK.

There has been no significant change in our exposure to market risk since
December 31, 2009. For discussion of our exposure to market risk, refer to Part II Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2009 under the heading Market Risk.





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
