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, 2007 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, 2007.

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 2008 and 2007 ended on March 29, 2008
and March 31, 2007, respectively.

Certain reclassifications have been made to the 2007 financial statements to conform to the 2008 presentation.

2.  STOCK-BASED COMPENSATION

We grant stock options, restricted stock
awards and restricted stock units to employees, officers, and directors under our current stock plans. Stock-based compensation expense is estimated as of the grant date based on the fair value of the award and is recognized as expense, net of
estimated forfeitures, on a straight-line basis 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 based on the quoted market price of our common stock at the date of grant. We granted 421 stock options and 377 restricted stock units during the three months ended March 29, 2008. We granted
255 stock options and 317 restricted stock units during the three months ended March 31, 2007. Stock-based compensation expense and related income tax benefits recognized in our condensed consolidated statements of operations were as follows:

For the three months ended March 29, 2008 and March 31, 2007, outstanding stock options and restricted stock units
amounting to 761 and 575, respectively, were excluded from the calculation of diluted earnings per share because of their antidilutive effect. Antidilutive options and restricted stock units could become dilutive in the future. In addition, shares
issuable for the conversion premium upon conversion of the 3.75 percent convertible senior notes were excluded from the calculation of diluted earnings per share as of March 29, 2008 and March 31, 2007 because our stock price had not
exceeded the conversion price.

13.  FAIR VALUE MEASUREMENTS

Effective January 1, 2008, we adopted the provisions of SFAS No. 157, Fair Value Measurements (SFAS No. 157), for our financial assets and liabilities. We expect to adopt the
provisions of SFAS No. 157 for non-financial assets and liabilities that are measured or recognized at fair value on a non-recurring basis on January 1, 2009, in accordance with the partial deferral of this standard by the Financial
Accounting Standards Board (the FASB). We are currently evaluating the effects of the provisions of SFAS No. 157 on our non-financial assets and liabilities that are measured or recognized at fair value on a non-recurring basis.
SFAS No. 157 defines fair value, establishes a framework for measuring fair value under accounting principles generally accepted in the United States of America, and enhances disclosures about fair value measurements. Fair value is defined
under SFAS No. 157 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market
participants on the measurement date. The adoption of SFAS No. 157 had no impact on previously reported results as all of the provisions were adopted prospectively. Subsequent changes in fair value of these financial assets and liabilities are
recognized in earnings when they occur, except for derivatives designated as cash flow hedges that are reported in other comprehensive income until the underlying transactions occur.

We also adopted the provisions of SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS No. 159), effective January 1, 2008. SFAS No. 159
allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. We have opted not to apply the fair value option to any of our
financial assets or liabilities in the three months ended March 29, 2008.

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.

Our valuation techniques are based on both observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources. Unobservable
inputs reflect our market assumptions. These two types of inputs create the following fair value hierarchy:



|         |  |

14.  CONTINGENCIES

We currently are not a party to any material legal proceedings and have no knowledge of any material legal proceeding contemplated by any governmental authority or third party. We are 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 will not, in the
aggregate, have a material adverse effect on our financial position, cash flows or results of operations.

15.  RECENT ACCOUNTING
PRONOUNCEMENTS

In June 2007, the EITF reached a consensus on EITF Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services
to Be Used in Future Research and Development Activities (EITF 07-3). EITF 07-3 requires companies that are involved in research and development activities to defer nonrefundable advance payments for future research and
development activities and to recognize those payments as goods and services are delivered. We are required to assess on an ongoing basis whether or not the goods or services will be delivered and to expense the nonrefundable advance payments
immediately if we determine that the delivery of such goods or services is unlikely. EITF 07-3 is effective for new arrangements entered into subsequent to the beginning of our fiscal year 2008. Adoption of EITF 07-3 did not have a material impact
on our financial position or results of operations.

In December 2007, the FASB issued SFAS No. 141 (Revised 2007), Business Combinations (SFAS No. 141(R)), which replaces SFAS No. 141,
Business Combinations. SFAS No. 141(R) retains the underlying concepts of SFAS No. 141 in that all business combinations are still required to be accounted for at fair value under the acquisition method. However, SFAS
No. 141(R) changes the method of applying the acquisition method in a number of significant aspects: acquisition costs will generally be expensed as incurred; noncontrolling interests will be valued at fair value at the acquisition date;
in-process research and development will be recorded at fair value as an indefinite-lived intangible asset at the acquisition date; restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition
date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. SFAS No. 141(R) is effective on a prospective basis for all business combinations for
which the acquisition date is on or after the beginning of the first annual period subsequent to December 15, 2008, with the exception of the accounting for valuation allowances on deferred taxes and acquired tax contingencies. SFAS
No. 141(R) amends SFAS No. 109 such that adjustments made to valuation allowances on deferred taxes and acquired tax contingencies associated with acquisitions that closed prior to the effective date of SFAS No. 141(R) would also
follow the provisions of SFAS No. 141(R). Early adoption of the provisions of SFAS No. 141(R) is not permitted. We are currently evaluating the effects that SFAS No. 141(R) may have on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statementsan amendment of ARB
No. 51 (SFAS No. 160). This statement is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008, with earlier adoption prohibited. This statement
requires the recognition of a noncontrolling interest (minority interest) as equity in the consolidated financial statements and separate from the parents equity. The amount of net income attributable to the noncontrolling interest will be
included in consolidated net income on the face of the income statement. It also amends certain consolidation procedures for consistency with the requirements of SFAS No. 141(R).This statement also includes expanded disclosure
requirements regarding the interests of the parent and its noncontrolling interest. We are currently evaluating this new statement and anticipate that the statement will not have a significant impact on the reporting of our results of operations.

In December 2007, the EITF issued Issue No. 07-1, Accounting for Collaborative Arrangements (EITF 07-1). EITF 07-1 is effective
for financial statements issued for fiscal years beginning after December 15, 2008 and interim periods within those fiscal years, and shall be applied retrospectively to all prior periods presented for all collaborative arrangements existing as
of the effective date. EITF 07-1 requires that transactions with third parties (i.e., revenue generated and costs incurred by the partners) should be reported in the appropriate line item in each companys financial statements pursuant to the
guidance in EITF Issue No. 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent. EITF 07-1 also includes enhanced disclosure requirements regarding the nature and purpose of the arrangement, rights and
obligations under the arrangement, accounting policy, amount and income statement classification of collaboration transactions between the parties, and amounts due from or owed to other participants under the collaborative arrangements. We are
currently evaluating the effects that EITF 07-1 may have on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161,
Disclosures about Derivative Instruments and Hedging Activitiesan amendment of FASB Statement No. 133 (SFAS No. 161). SFAS No. 161 is intended, through additional qualitative and quantitative
disclosures on derivatives, to provide users of financial statements with enhanced understanding of how and why an entity uses derivative instruments; how derivative instruments and related hedged items are accounted for under SFAS No. 133; and
how derivative instruments and related hedged items affect an entitys financial position, results of operations, and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning
after November 15, 2008, with early adoption encouraged. We expect to adopt this standard effective January 1, 2009. We are currently evaluating the disclosure implications of this statement.

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, 2007. 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 2008 and 2007 ended on March 29, 2008 and March 31, 2007,
respectively.

General Overview

We are a global leader in life
science providing innovative products, services, and solutions so our customers can advance their research, development, and production. Our academic, biotechnology, and pharmaceutical customers use our consumable products and services to increase
their speed and to improve their consistency while saving costs in laboratory applications and in biopharmaceutical manufacturing. With our extensive technical expertise and applications knowledge, we have the unique ability to engage in
peer-to-peer discussions with scientists to help them confront challenging scientific and human health issues.

We are organized around two operating divisions. Our
Bioscience Division improves laboratory productivity and workflows by providing innovative products and technologies for life science research. Our Bioprocess Division helps pharmaceutical and biotechnology companies develop their manufacturing
processes, optimize their manufacturing productivity, and ensure the quality of drugs.

We provide a wide range of products and services to a range of customers
across a range of geographies. The breadth of our business portfolio allows us to target growth on a number of dimensions, rather than relying on any single business, market, or economy.

The following table sets forth revenues derived from the Bioprocess and Bioscience divisions as a percentage of our total revenues.

PART I



The balance in our business portfolio between Bioprocess and Bioscience products and services and the strength of our global market reach into Europe and Asia/Pacific allowed us to
mitigate much of the weakness experienced by our Bioprocess Division in North America during the 2008 first quarter. Our Bioscience Division reported good revenue growth in the 2008 first quarter that largely offset the weakness experienced by our
Bioprocess Division.

The consolidated revenue increase of 7 percent to $396.2 million in the 2008 first quarter reflected a favorable effect of
changes in foreign currency translation rates of 8 percent. Excluding the effect of foreign currency translation, consolidated revenues decreased 1 percent during the 2008 first quarter as a result of continued weakness in sales to a handful of our
largest North American biotechnology customers. This decline was largely offset by the strength in sales of our laboratory water and our drug discovery products and services. Changes in product pricing had an insignificant effect on the
year-over-year comparison.

Our Bioprocess Division revenues declined 7 percent in the 2008 first quarter versus the prior year comparable period after adjusting for
the favorable effect of foreign currency translation. The decline was attributable to a lower volume of purchases from a handful of our largest North American biotechnology customers that have significantly reduced their rate of monoclonal antibody
production. We believe that these customers have re-evaluated market demand for their products and continue to reduce their inventories of certain monoclonal antibodies to lower their costs and improve working capital. Despite the lower demand from
these customers, we believe the overall biotechnology industry remains healthy. This is evidenced by the growth in a number of biologic drugs and vaccines, investments in new biologic facilities, and continued private equity investments in the
biotechnology industry. We expect Bioprocess revenues to grow in the second half of 2008 versus the prior year comparable period.

Our Bioscience Division revenues
grew 6 percent in the 2008 first quarter after adjusting for the favorable effect of foreign currency translation. This growth was driven by strong sales of our laboratory water and our drug discovery products and services. Higher levels of academic
and pharmaceutical research, successful new product introductions, execution of our sales and marketing initiatives, and continued expansion of our new e-commerce business platform all contributed to this revenue growth. We expect these trends to
continue for the remainder of 2008.

Our 2008 first quarter operating income increased versus the prior year comparable period primarily as a result of higher sales
volume, a more profitable business mix, productivity improvements associated with our supply chain initiatives, and the lack of Serologicals related acquisition and integration costs. These increases were partially offset by the unfavorable effect
of foreign currency translation on our Euro based manufacturing operations in Ireland and France. The combination of these factors resulted in an increase of our 2008 first quarter operating profit margin by 3.9 percentage points to 15 percent from
the prior year comparable period.

Diluted earnings per share (EPS) of $0.59 in the 2008 first quarter increased $0.10 from the prior year comparable
period. This increase was primarily the result of our higher operating income and lower interest expense. Last years first

quarter included a $9.1 million benefit from the reversal of reserves related to uncertain tax positions upon the completion of tax audits and a statute of limitations
closure.

We generated $40.4 million of operating cash flows for the 2008 first quarter, which was a 320 percent increase over the prior year comparable period.
Operating cash flow generation in the 2008 first quarter was driven by our higher operating results. During the 2008 first quarter, we repaid $40.9 million of our long term debt. We will continue to focus on operating cash flow generation, which we
expect to use to further reduce our debt.

Bioprocess Division

Bioprocess revenues of $216.6 million for the 2008 first quarter increased $2.3 million, or 1 percent versus the prior year comparable period. The 2008 first quarter increase included a favorable foreign currency translation effect of 8
percent. Adjusting for this item, Bioprocess revenues declined 7 percent in the 2008 first quarter. The decrease was primarily attributable to lower sales of our products used in biopharmaceutical manufacturing, such as chromatography media, systems
hardware, sterilization products, and cell culture supplements. These decreases were the result of a continued decline in sales to a handful of our largest North American biotechnology customers. These decreases were also partially the result of
fewer approvals of new biologic drugs in recent quarters. New biologic drug approvals are a significant driver of our Bioprocess revenue growth. The lower demand for our products from biopharmaceutical drug customers has had an adverse effect on our
sales since the 2007 third quarter.

From a geographic perspective and excluding the favorable foreign currency translation effect, revenues in the Americas, Europe
and Asia/Pacific decreased $20.5 million, increased $1.5 million, and increased $4.9 million, respectively, in the 2008 first quarter over the prior year comparable period. The decrease in Americas was primarily the result of continued

lower sales to a handful of our largest biotechnology customers. The increase in Europe was primarily driven by sales of our process monitoring tools and upstream
processing products. The increase in Asia/Pacific was primarily driven by strong sales of downstream processing products in Japan.

Bioscience
Division

Bioscience revenues of $179.6 million for the 2008 first quarter increased $21.9 million, or 14 percent versus the prior year comparable period. The
increase included a favorable foreign currency translation effect of 8 percent. Adjusting for this item, Bioscience revenues grew 6 percent, which was primarily driven by continued strong demand for our laboratory water products and services. New
product introductions and continued growth of our consumables and services business contributed to this strength. Our drug discovery business also contributed to the revenue growth in the 2008 first quarter, particularly for sales of our biomarker
and immunoassay products and services.

From a geographic perspective and excluding the favorable foreign currency translation effect, revenues in the Americas,
Europe, and Asia/Pacific increased $2.6 million, $3.8 million, and $2.7 million, respectively, in the 2008 first quarter over the prior year comparable period. The increases in the Americas and Europe were primarily the result of the strength of our
laboratory water and our drug discovery businesses. The growth in Asia/Pacific was primarily from strong sales of laboratory water products in Japan.

|Gross profit margin |  |                    | 53    | % |               |   | 51    | %

Gross profit increased $18.3 million, or 10 percent, in the 2008 first quarter versus the prior year comparable period. The
primary drivers of the increase in gross profit were: (i) the absence of Serologicals business acquisition inventory fair value adjustments in the 2008 first quarter, (ii) an improved business mix as a result of higher Bioscience revenues
and lower sales of Bioprocess systems and chromatography media products, (iii) productivity improvements, and (iv) lower spending as a result of our supply chain initiatives. Although foreign currency translation also contributed to the
gross profit increase, the strengthening of the Euro and its effect on our significant manufacturing costs in Ireland and France reduced our gross profit margins.

Amortization of acquired intangible assets remained consistent at $2.4 million in the 2008 first quarter versus the prior year comparable period. We expect 2008 full year amortization affecting gross profit to be approximately $9.4 million.
Costs associated with our focused factory initiatives (primarily employee separation costs, facility closure costs and accelerated depreciation) also lowered our gross profit both this quarter and in the prior year comparable period. These costs
amounted to $2.2 million for the 2008 first quarter versus $3.7 million for the prior year comparable period. Although we exited the last manufacturing facility pursuant to our focus factory initiative in the 2008 first quarter, we plan to continue
to improve our operational effectiveness for the remainder of 2008, which will include the relocation of that facility and additional manufacturing operations and product lines. We expect 2008 full year costs associated with these actions to be
between $7 and $12 million.

Selling, general and administrative (SG&A) expenses increased $2.7 million, or 2 percent, in the 2008 first
quarter versus the prior year comparable period. Excluding the effect of unfavorable foreign currency translation, SG&A expenses decreased by $3.9 million, or 3 percent, in the 2008 first quarter versus the prior year comparable period. The
primary driver of the lower SG&A expenses was the absence of Serologicals integration costs in the 2008 first quarter. The integration of Serologicals was substantially complete as of the end of the 2007 second quarter. Amortization expense
related to acquired intangible assets was $13.5 million in the 2008 first quarter versus $12.2 million in the prior year comparable period. We expect 2008 full year amortization of intangible assets to be approximately $53.8 million as compared with
$48.9 million in 2007.

Research and development (R&D) expenses decreased $2.5 million, or 9 percent, for the 2008 first quarter
versus the prior year comparable period. Foreign currency translation did not contribute significantly to this change. The decrease was primarily the result of lower discretionary spending in the 2008 first quarter versus the prior year comparable
period. We expect R&D expenses to remain approximately 6 to 7 percent of net sales for the remainder of 2008.

Interest income decreased $0.4 million, or 76 percent, for the 2008 first quarter versus the prior year comparable period.
This was the result of lower rates earned on investment balances. Available cash in excess of operating needs was used to repay our debt.

Interest expense decreased
$2.0 million, or 12 percent, for the 2008 first quarter versus the prior year comparable period. The decrease was primarily the result of lower overall debt balances as we continued to repay our debt. Our average interest rate remained relatively
flat compared with the prior year as the increase in the average interest rate on our revolver borrowings was offset by a decrease attributable to the repayment of our $100.0 million 7.5 percent ten-year unsecured

notes in April 2007. Our revolving credit facility is comprised of floating rate borrowings based on LIBOR. Increases or decreases in these rates would cause increases
or decreases to our interest expense, respectively.

In August 2007, the Financial Accounting Standards Board (the FASB) proposed FASB Staff Position
(FSP) APB 14-a, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (the Proposed FSP). In March 2008, the FASB reaffirmed the
accounting conclusions of the Proposed FSP, with the final FSP expected to be issued in May 2008. The Proposed FSP would require the proceeds from the issuance of such convertible debt instruments to be allocated between a liability component
(issued at a discount) and an equity component. The portion allocated to the equity component would be recorded as a discount on the debt which would be amortized over the period the convertible debt is expected to be outstanding. The Proposed FSP
would change the accounting treatment for our $565.0 million of 3.75 percent convertible senior notes that were issued in June 2006. Such a change would impact the presentation of our consolidated financial statements and would result in an increase
to our non-cash interest expense. The provisions of the Proposed FSP would be applied retrospectively beginning in January 2009.

|Effective income tax rate |  | 22                 | % |  | (19           | )%

Our effective tax rate was 22 percent for the 2008 first quarter versus (19) percent for the prior year comparable
period. During the 2007 first quarter, we recorded $9.1 million of previously unrecognized tax benefits as a result of the completion of tax examinations and the expiry of a statute of limitations. This resulted in a net tax benefit of $4.4 million
for the 2007 first quarter compared to a tax provision of $9.6 million for the 2008 first quarter. Adjusting for the effect of this $9.1 million in tax benefits, our 2007 first quarter effective tax rate was 20 percent. The higher current year rate
was caused by a shift in the jurisdictional mix of our profits to higher tax rate jurisdictions. On a full year basis, we expect our effective income tax rate to be approximately 22 percent.

Net income increased $5.9 million, or 22 percent, for the 2008 first quarter versus the prior year comparable period.
The increase was primarily the result of higher 2008 operating income partially offset by the higher effective tax rate.

Diluted earnings per share increased $0.10,

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 operations, 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 acquisitions, deterioration in certain
financial ratios, and market changes in general.

Our ability to obtain debt financing at comparable risk-based interest rates is partly a function of our existing
debt to capitalization levels as well as our current credit standing. Our credit ratings are reviewed regularly by major debt rating agencies such as Standard & Poors and Moodys Investors Service. Our senior unsecured notes are
rated BBB by Standard & Poors and Ba2 by Moodys Investors Service and our revolving credit facility is rated BBB and Baa2 by Standard and Poors and Moodys Investors Service, respectively. Our senior convertible notes
are rated BB- by Standard & Poors and have not been rated by Moodys Investors Service.

We believe our future operating cash flows will be
sufficient to meet our future operating and investing cash needs. Furthermore, our ability to obtain equity financing, as well as availability of additional borrowings under our revolving credit facility, provide additional potential sources of
liquidity should they be required.

In the 2008 first quarter, we continued our focus on debt repayment. We will continue to maintain our cash balances at a level
that better reflects the minimum operating needs of our subsidiaries in which we conduct our business. The repatriation of cash balances from certain of our subsidiaries could have adverse tax consequences. However, these cash balances are generally
available without legal restrictions to fund ordinary business operations. We have transferred, and will continue to transfer, cash between our subsidiaries to pay down our debt when it is cost effective to do so.

PART I



OPERATING CASH FLOWS

Cash provided by operating activities was $40.4 million for
the 2008 first quarter and was primarily attributable to our net income of $32.6 million, non-cash adjustments for depreciation and amortization expenses of $32.6 million, and other non-cash expenses of $8.6 million. These factors were partially
offset by an increase in our working capital of $33.4 million. The increase in our working capital from December 31, 2007 to March 29, 2008 was primarily attributable to increases in accounts receivable of $20.2 million because our
collection efforts were adversely affected by the timing of holidays in Europe. The working capital increase was also caused by a decrease in accrued expenses of $7.6 million primarily attributable to payments of accrued incentive compensation as
well as a decrease in accounts payable of $6.9 million primarily attributable to the timing of vendor payments.

Days supply in inventory remained stable at 138 days
at March 29, 2008 compared with December 31, 2007. Days supply in inventory was 127 days at March 31, 2007. Days sales outstanding in ending accounts receivable was 74 days at March 29, 2008 compared to 67 days at both
December 31, 2007 and March 31, 2007. The increase in days sales outstanding was attributable to the impact of our European collection efforts discussed above.

INVESTING CASH FLOWS

Cash used for investing activities was $16.5 million during the 2008 first quarter. We paid $13.5 million for capital
expenditures and $3.1 million for the acquisition of various technology and distribution rights. We expect our full year 2008 capital expenditures to be at or below the 2007 level of $102 million.

FINANCING CASH FLOWS

Cash used for financing activities was $31.5 million
during the 2008 first quarter. Net repayments under our revolving credit facility amounted to $40.9 million. Debt reduction is the primary use for the free cash flow (defined as net cash provided by operations less additions to property, plant and
equipment) we generate. Additionally, we received proceeds of $9.2 million from the issuance of common stock under our stock plans and paid dividends of $0.9 million to our joint venture partner during the 2008 first quarter.

FINANCING COMMITMENTS

Short-term debt

Short-term debt at March 29, 2008 consisted of borrowings under our operating bank facilities.

Revolving credit facility

At March 29, 2008, we had a commitment under our revolving credit agreement amounting to 465.0 million, or $734.8 million. At March 29, 2008, we had 280.2 million, or $442.8 million, available for borrowing under the revolving credit agreement. This credit agreement expires June 6, 2011.

We are required to maintain certain leverage and interest coverage ratios set forth in the revolving credit agreement. As of March 29, 2008, we were compliant with all financial covenants specified in the revolving 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.

|Minimum interest coverage ratio |  | 3.50:1.0    |  | 5.94:1.0               

As of March 29, 2008, we had borrowings under our revolving credit facility of 184.8 million, or $292.0 million. The borrowings were classified as long-term debt because of our ability and intent to continuously refinance such borrowings. For the 2008 first quarter,
the weighted average interest rate for the revolving credit facility was 4.39 percent.

3.75% convertible senior notes due 2026

In June 2006, we issued $565.0 million in aggregate principal amount of 3.75 percent convertible notes in a private placement offering.

5.875% senior notes due 2016

In June 2006, we issued 250.0 million, or $395.1 million, in aggregate principal amount of 5.875 percent senior notes.

Legal Matters

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

Following our decision to consolidate the results of our 40 percent owned Indian Joint-Venture (the India JV) in January 2006, we learned as a result of our internal
control 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, our Audit and Finance Committee engaged outside counsel and
commenced an investigation. We have implemented certain corrective actions. We have 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 us.

Critical Accounting 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 48, in our
Annual Report on Form 10-K for the year ended December 31, 2007. 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.

PART I



New Accounting Pronouncements

We adopted the provisions of Statement of
Financial Accounting Standards (SFAS) No. 157, Fair Value Measurements (SFAS No. 157), effective January 1, 2008 for our financial assets and liabilities. We expect to adopt the provisions of
SFAS No. 157 for non-financial assets and liabilities that are measured or recognized at fair value on a non-recurring basis on January 1, 2009, in accordance with the partial deferral of this standard by the FASB. We are currently
evaluating the effects of the provisions of SFAS No. 157 on our non-financial assets and liabilities that are measured or recognized at fair value on a non-recurring basis. SFAS No. 157 defines fair value, establishes a framework for measuring
fair value under accounting principles generally accepted in the United States of America, and enhances disclosures about fair value measurements. Fair value is defined under SFAS No. 157 as the exchange price that would be received for an
asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The adoption of SFAS No. 157 had no
impact on previously reported results as all of the provisions were adopted prospectively. Subsequent changes in fair value of these financial assets and liabilities are recognized in earnings when they occur, except for derivatives designated as
cash flow hedges that are reported in other comprehensive income until the underlying transactions occur.

In June 2007, the Emerging Issues Task Force
(EITF) reached a consensus on EITF Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future Research and Development Activities (EITF 07-3). EITF 07-3
requires companies that are involved in research and development activities to defer nonrefundable advance payments for future research and development activities and to recognize those payments as goods and services are delivered. We will be
required to assess on an ongoing basis whether or not the goods or services will be delivered and to expense the nonrefundable advance payments immediately if we determine that the delivery of such goods or services is unlikely. EITF 07-3 is
effective for new arrangements entered into subsequent to the beginning of our fiscal year 2008. Adoption of EITF 07-3 did not have a material impact on our financial position or results of operations.

In December 2007, the FASB issued SFAS No. 141 (Revised 2007), Business Combinations (SFAS No. 141(R)), which replaces SFAS No. 141,
Business Combinations. SFAS No. 141(R) retains the underlying concepts of SFAS No. 141 in that all business combinations are still required to be accounted for at fair value under the acquisition method. However, SFAS
No. 141(R) changes the method of applying the acquisition method in a number of significant aspects: acquisition costs will generally be expensed as incurred; noncontrolling interests will be valued at fair value at the acquisition date;
in-process research and development will be recorded at fair value as an indefinite-lived intangible asset at the acquisition date; restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition
date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. SFAS No. 141(R) is effective on a prospective basis for all business combinations for
which the acquisition date is on or after the beginning of the first annual period subsequent to December 15, 2008, with the exception of the accounting for valuation allowances on deferred taxes and acquired tax contingencies. SFAS
No. 141(R) amends SFAS No. 109 such that adjustments made to valuation allowances on deferred taxes and acquired tax contingencies associated with acquisitions that closed prior to the effective date of SFAS No. 141(R) would also
follow the provisions of SFAS No. 141(R). Early adoption provisions of SFAS No. 141(R) is not permitted. We are currently evaluating the effects that SFAS No. 141(R) may have on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statementsan amendment of ARB No. 51
(SFAS No. 160). This statement is effective for fiscal years, and interim periods within

those fiscal years, beginning on or after December 15, 2008, with earlier adoption prohibited. This statement requires the recognition of a noncontrolling
interest (minority interest) as equity in the consolidated financial statements and separate from the parents equity. The amount of net income attributable to the noncontrolling interest will be included in consolidated net income on the face
of the income statement. It also amends certain consolidation procedures for consistency with the requirements of SFAS No. 141(R).This statement also includes expanded disclosure requirements regarding the interests of the parent and
its noncontrolling interest. We are currently evaluating this new statement and anticipate that the statement will not have a significant impact on the reporting of our results of operations.

In December 2007, the EITF issued Issue No. 07-1, Accounting for Collaborative Arrangements (EITF 07-1). EITF 07-1 is effective for financial
statements issued for fiscal years beginning after December 15, 2008 and interim periods within those fiscal years, and shall be applied retrospectively to all prior periods presented for all collaborative arrangements existing as of the
effective date. EITF 07-1 requires that transactions with third parties (i.e., revenue generated and costs incurred by the partners) should be reported in the appropriate line item in each companys financial statements pursuant to the guidance
in EITF Issue No. 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent. EITF 07-1 also includes enhanced disclosure requirements regarding the nature and purpose of the arrangement, rights and obligations
under the arrangement, accounting policy, amount and income statement classification of collaboration transactions between the parties, and amounts due from or owed to other participants under the collaborative arrangements. We are currently
evaluating the effects that EITF 07-1 may have on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, Disclosures
about Derivative Instruments and Hedging Activitiesan amendment of FASB Statement No. 133 (SFAS No. 161). SFAS No. 161 is intended, through additional qualitative and quantitative disclosures on
derivatives, to provide users of financial statements with enhanced understanding of how and why an entity uses derivative instruments; how derivative instruments and related hedged items are accounted for under SFAS No. 133; and how derivative
instruments and related hedged items affect an entitys financial position, results of operations, and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after
November 15, 2008, with early adoption encouraged. We expect to adopt this standard effective January 1, 2009. We are currently evaluating the disclosure implications of this statement.

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
Annual Report on Form 10-K for the year ended December 31, 2007.





ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There has been no significant change in our exposure to market risk since December 31, 2007. 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, 2007 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 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 March 29, 2008 that has materially affected, or is reasonably likely to materially
affect, internal control over financial reporting.
