The accompanying unaudited notes are an integral part of these condensed consolidated financial statements.

The condensed consolidated financial statements included herein have been prepared by PerkinElmer, Inc. (the “Company”), without audit, in accordance with the accounting principles generally accepted in the United States and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information in the footnote disclosures of these financial statements has been condensed or omitted which substantially duplicates information provided in the Company’s latest audited financial statements in accordance with the rules and regulations of the SEC. These financial statements should be read in conjunction with the Company’s financial statements and notes included in its Annual Report on Form 10-K for the fiscal year ended January 1, 2006, filed with the SEC (the “2005 Form 10-K”). The balance sheet amounts at January 1, 2006 in this report were derived from the Company’s audited 2005 financial statements included in the 2005 Form 10-K. Certain prior period amounts related to discontinued operations have been reclassified to conform to the current-year financial statement presentation. The financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the Company’s results of operations, financial position and cash flows for the periods indicated. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The results of operations for the six months ended July 2, 2006 and July 3, 2005 are not necessarily indicative of the results for the entire fiscal year or any future period.

Effective January 2, 2006, the Company adopted Statement of Financial Accounting Standards (“SFAS”) No. 123(R), “Share-Based Payment” (“SFAS No. 123(R)”), which requires compensation costs related to stock-based transactions, including employee stock options, to be recognized in the financial statements based on fair value. SFAS No. 123(R) revises SFAS No. 123, as amended, “Accounting for Stock-Based Compensation,” and supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees.” The Company adopted SFAS No. 123(R) using the modified prospective application transition method. Under this method, compensation cost, measured using fair value, is recognized for the unvested portion of stock-based payments granted prior to January 2, 2006 and all stock-based payments granted subsequent to January 1, 2006 over the related vesting period. Prior to the first quarter of 2006, the Company applied the intrinsic value based method prescribed in APB Opinion No. 25 in accounting for employee stock-based compensation. In accordance with the modified prospective method, prior period results have not been restated and are not directly comparable to periods after adoption. Due to the adoption of SFAS No. 123(R), the Company’s results for the three and six months ended July 2, 2006 include incremental stock-based compensation expense totaling $2.1 million and $3.8 million, respectively.

In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in the financial statements of an entity in accordance with SFAS No. 109, “Accounting for Income Taxes.” The new interpretation is effective for fiscal years beginning after December 15, 2006. The Company will be required to adopt the interpretation in the first quarter of fiscal year 2007. Management is currently evaluating the requirements of FIN 48 and has not yet determined the impact on the Company’s consolidated financial statements.

Acquisition of Agilix Corporation. In February 2006, the Company acquired certain assets of Agilix Corporation (“Agilix”) for approximately $8.7 million in cash plus potential additional contingent consideration, which management expects to be immaterial to the Company. Assets acquired primarily relate to Agilix’s core technology which centers around labeling technology using isobaric mass tags that allows for the simultaneous quantification of molecules, such as proteins, from multiple samples. Agilix’s operations are reported within the results of the Company’s Life and Analytical Sciences segment from the acquisition date. This acquisition did not have a material effect on the Company’s financial position, results of operations or cash flows.

Acquisition of Spectral Genomics, Inc. In April 2006, the Company acquired certain assets and liabilities of Spectral Genomics, Inc. (“Spectral”), a leader in molecular karyotyping technology used to evaluate chromosomal abnormalities. Consideration for the transaction was approximately $12.0 million in cash plus potential additional contingent consideration, which management expects to be immaterial to the Company. Spectral’s operations are reported within the results of the Company’s Life and Analytical Sciences segment from the acquisition date. This acquisition did not have a material effect on the Company’s financial position, results of operations or cash flows.

Acquisition of Clinical & Analytical Service Solutions Ltd. In June 2006, the Company acquired the stock of Clinical & Analytical Service Solutions Ltd. (“C&A”), a scientific equipment asset and managed maintenance company serving the pharmaceutical, biotechnology and healthcare markets. Consideration for the transaction was approximately $12.3 million in cash plus potential additional contingent consideration, which management expects to be immaterial to the Company. C&A’s operations are reported within the results of the Company’s Life and Analytical Sciences segment from the acquisition date. This acquisition did not have a material effect on the Company’s financial position, results of operations or cash flows.

The acquisitions were accounted for in accordance with SFAS No. 141, “Business Combinations” (“SFAS No. 141”), and the Company has accordingly allocated the purchase price of the acquisitions based upon the fair values of the assets acquired and liabilities assumed. In connection with the fair valuing of the assets acquired and liabilities assumed, management, assisted by valuation consultants, performed an assessment of intangible assets using customary valuation procedures and techniques.

The components of the preliminary purchase price and allocation are as follows (in thousands):

Acquisition of J.N. Macri Technologies LLC and NTD Laboratories, Inc. Subsequent to the quarter ended July 2, 2006, the Company acquired certain assets and liabilities of J.N. Macri Technologies LLC (“Macri”) and

the stock of NTD Laboratories, Inc. (“NTD”). Macri holds and licenses global patents related to free beta Human Chorionic Gonadotropin (“free Beta hCG”). Free Beta hCG is a peptide hormone produced in the early stage of pregnancy that is widely recognized as an important biomarker for first-trimester prenatal risk assessment. NTD is a laboratory specializing in prenatal risk assessment and offers laboratory developed and validated testing under the brand name UltraScreen^®, of which free Beta hCG is an important component. Aggregate consideration for these transactions was $56.65 million in cash, subject to a net working capital adjustment. Both the Macri and NTD operations will be reported within the results of the Company’s Life and Analytical Sciences segment from the acquisition date.

The Company has undertaken a series of restructuring actions related to the impact of acquisitions, divestitures and the integration of its business units. Restructuring actions were recorded in accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.” In certain instances, specifically when governmental authorities are involved in setting severance levels, SFAS No. 112, “Employers’ Accounting for Postemployment Benefits,” is applied. The principal actions associated with these plans related to workforce reductions and overhead reductions resulting from reorganization activities, including the closure of certain manufacturing and selling facilities. Details of these plans are discussed more fully in the Company’s 2005 Form 10-K.

On June 28, 2006, the Company’s management approved a plan to terminate employees in two locations in the U.S. as the Company shifts resources into product lines that are more consistent with the Company’s growth strategy. The Company completed notifying affected employees on June 30, 2006. As a result of this plan of termination, the Company recorded a pre-tax restructuring charge of $0.8 million during the second quarter of 2006 (the “Q2 2006 Plan”). The actions within the Q2 2006 Plan related to a workforce reduction resulting from reorganization activities within the Life and Analytical Sciences business.

In addition, during the second quarter of 2006, the Company recorded a pre-tax restructuring charge of $0.4 million relating to its restructuring plan in the fourth quarter of 2005 (the “Q4 2005 Plan”) due to higher than expected costs associated with the termination of employees in Europe within the Life and Analytical Sciences segment. The Company also recorded a pre-tax restructuring reversal of $1.4 million relating to the Q4 2005 Plan due to the completion in June 2006 of the sale of a building previously reserved for in the Q4 2005 Plan. The amount of the proceeds from this sale in excess of the current book value of the property was recorded as a restructuring reversal within the Optoelectronics segment.

A description of each of the restructuring plans and the activity recorded for the six month period ended July 2, 2006 is as follows:

During the second quarter of 2006, the Company recognized a $0.8 million restructuring charge in the Life and Analytical Sciences segment. The purpose of this restructuring action was to shift resources into product lines that were more consistent with the Company’s growth strategy. The actions in the Q2 2006 Plan were headcount reductions resulting from reorganization activities.

The following table summarizes the components of the Q2 2006 Plan activity for the six months ended July 2, 2006:

All actions related to the Q2 2006 Plan were completed by the end of the second quarter of 2006, and the Company anticipates that all payments will be completed by the end of 2006.

During the fourth quarter of 2005, the Company recognized a $2.2 million restructuring charge in the Life and Analytical Sciences segment and a $6.0 million restructuring charge in the Optoelectronics segment (the “Q4 2005 Plan”). The purpose of these restructuring actions was to shift resources into geographic regions and product lines that were more consistent with the Company’s growth strategy. The principal actions in the Q4 2005 Plan were headcount reductions and the closure of several facilities resulting from reorganization activities.

During the second quarter of 2006, the Company recorded a pre-tax restructuring charge of $0.4 million relating to its Q4 2005 restructuring plan due to higher than expected costs associated with the termination of employees in Europe within the Life and Analytical Sciences segment. The Company also recorded a pre-tax restructuring reversal of $1.4 million relating to its Q4 2005 restructuring plan due to the completion in June 2006 of the sale of a building previously reserved for in the Q4 2005 Plan. The amount of the proceeds from this sale in excess of the current book value of the property was recorded as a restructuring reversal within the Optoelectronics segment.

The following table summarizes the components of the Q4 2005 Plan activity for the six months ended July 2, 2006:

During the second quarter of 2005, the Company recognized a $5.3 million restructuring charge in the Life and Analytical Sciences segment and a $2.9 million restructuring charge in the Optoelectronics segment (the “Q2 2005 Plan”). The purpose of these restructuring actions was to shift resources into geographic regions and product lines that were more consistent with the Company’s growth strategy. The principal actions in the Q2 2005 Plan comprised headcount reductions resulting from reorganization activities.

The following table summarizes the components of the Q2 2005 Plan activity for the six months ended July 2, 2006:

All actions related to the Q2 2005 Plan have been completed and the Company anticipates that payments will be completed by the end of 2006.

The Company has approximately $6.5 million of remaining liabilities associated with 2001 to 2003 restructuring and integration plans, primarily relating to remaining lease obligations of closed facilities. The remaining terms of these leases vary in length but all will be completed by 2014.

Senior Unsecured Credit Facility. On October 31, 2005, the Company entered into a $350.0 million five-year senior unsecured revolving credit facility. This facility replaced its previous $100.0 million five-year revolving credit facility. Letters of credit in the aggregate amount of approximately $15.0 million, originally issued under its previous credit agreement, are treated as issued under this new agreement. The Company uses the senior unsecured credit facility for general corporate purposes which may include working capital, refinancing existing indebtedness, capital expenditures, share repurchases, acquisitions and strategic alliances. The interest rates under the senior unsecured credit facility are based on the Eurocurrency rate at the time of borrowing plus a margin or the base rate from time to time. The Eurocurrency margin as of July 2, 2006 was 60 basis points. The base rate is the higher of (1) the corporate base rate announced from time to time by Bank of America, N.A. and (2) the Federal Funds rate plus 50 basis points. The Company may allocate all or a portion of its indebtedness under the senior unsecured credit facility to interest based upon the Eurocurrency rate plus a margin or the base rate. As of July 2, 2006, all borrowings under the senior unsecured credit facility were allocated to interest based on the Eurocurrency rate plus a margin. The weighted-average Eurocurrency interest rate as of July 2, 2006 was 3.03%, resulting in a weighted-average effective Eurocurrency rate, including the margin, of 3.63%. There were approximately $199.0 million of borrowings under the facility as of July 2, 2006, which were undertaken by certain foreign subsidiaries of the Company. The funds were borrowed in the subsidiaries’ functional currencies of Euro (EUR), Canadian Dollars (CAD) and Japanese Yen (JPY). The agreement contains affirmative, negative and financial covenants and events of default customary for financings of this type. The financial covenants include interest coverage and debt-to-EBITDA ratios. The Company was in compliance with all covenants as of July 2, 2006.

Basic earnings per share was computed by dividing net income by the weighted-average number of common shares outstanding during the period less restricted unvested shares. Diluted earnings per share was computed by dividing net income by the weighted-average number of common shares outstanding plus all potentially dilutive common stock equivalents, primarily shares issuable upon the exercise of stock options using the treasury stock method:

Antidilutive securities include outstanding stock options with exercise prices and average unrecognized compensation cost in excess of the average fair market value of our common stock for the related period. Antidilutive options were excluded from the calculation of diluted net income per share and could become dilutive in the future.

The components of accumulated other comprehensive income, net of tax were as follows:

The Company follows SFAS No. 131, “Disclosures About Segments of an Enterprise and Related Information.” SFAS No. 131 establishes standards for the way public business enterprises report information about operating segments in annual financial statements and in interim reports to shareholders. The method for determining what information to report is based on the way that management organizes the segments within the Company for making operating decisions and assessing financial performance. In evaluating financial performance, management uses operating profit as the measure of the segments’ profit or loss. Based on the guidance in SFAS No. 131, the Company has two operating segments for financial reporting purposes. The operating segments and their principal products and services are:

As part of its continued efforts to focus on higher growth opportunities, the Company has discontinued certain businesses. The Company has accounted for these businesses as discontinued operations in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” and, accordingly, has presented the results of operations and related cash flows as discontinued operations for all periods presented. The assets and liabilities of these businesses have been presented separately and are reflected within the assets and liabilities from discontinued operations in the accompanying balance sheets as of July 2, 2006 and January 1, 2006.

In September 2005, the Company’s Board of Directors approved a plan to divest its Fluid Sciences segment. The Fluid Sciences segment consisted of three businesses—Aerospace, Fluid Testing and Semiconductor. In November 2005, the Company sold the Fluid Testing division to Caleb Brett USA Inc. for approximately $34.5 million, resulting in a net pre-tax gain of $30.3 million. In December 2005, the Company sold the Aerospace division to Eaton Corporation for approximately $333.0 million, resulting in a net pre-tax gain of $250.6 million. These gains were recognized during fiscal 2005 as gains on the disposition of discontinued operations. The Company received total cash proceeds in these transactions of approximately $361.1 million. During the first six months of 2006, the Company finalized the net working capital adjustments associated with the sales of these

businesses and settled a claim related to an employee benefit program, resulting in the recognition of losses of $1.3 million and $0.2 million relative to the Aerospace business and the Fluid Testing business, respectively. On February 27, 2006, the Company sold substantially all of the assets of its Semiconductor business for approximately $26.5 million (subject to a net working capital adjustment) plus potential additional contingent consideration. A pre-tax gain of $3.7 million, exclusive of additional contingent consideration, was recognized in the first six months of 2006.

In June 2005, the Company’s Board of Directors approved a plan to shut down the Company’s Fiber Optics Test Equipment business. In December 2005, the Company’s Board of Directors approved a plan to sell its Lithography business. The results of these businesses were previously reported as part of the Optoelectronics reporting segment. The completion of the shut-down of the Fiber Optics Test Equipment business resulted in a pre-tax loss of $5.2 million related to lease and severance costs and the reduction of fixed assets and inventory to net realizable value. The Company recognized the net loss during fiscal 2005.

During 2006 and 2005, the Company settled various claims under certain long-term contracts and transition services with its Technical Services business, which was sold in August of 1999.

The table below summarizes the gains and losses on dispositions of discontinued operations, as discussed above:

Summary operating results of the discontinued operations of the Fluid Sciences segment, and the Fiber Optics Test Equipment and Lithography businesses for the periods prior to disposition were as follows:

In December 2004, the FASB issued SFAS No.123(R) which requires compensation costs related to stock-based transactions, including employee stock options, to be recognized in the financial statements based on fair value. SFAS No. 123(R) revises SFAS No. 123, as amended, “Accounting for Stock-Based Compensation,” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.”

Effective January 2, 2006, the Company adopted the provisions of SFAS No. 123(R) using the modified prospective transition method. Accordingly, periods prior to adoption have not been restated and are not directly comparable to periods after adoption. Under the modified prospective method, compensation cost recognized in periods after adoption includes (i) compensation cost for all stock-based payments granted prior to, but not yet vested as of, January 2, 2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123, less estimated forfeitures, and (ii) compensation cost for all stock-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123(R), less estimated forfeitures.

Prior to January 2, 2006, the Company accounted for stock-based compensation plans in accordance with the provisions of APB Opinion No. 25, as permitted by SFAS No. 123. Under APB Opinion No. 25, the Company only recorded stock-based compensation expense for restricted stock, restricted stock units and performance units, which amounted to $0.7 million and $1.1 million, net of related taxes, for the three and six months ended July 3, 2005, respectively. Under APB 25, the Company was not required to recognize compensation expense for the cost of stock options, when such options had an exercise price equal to the market price at the date of grant, or shares issued under the Company’s ESPP. If the fair value based method as prescribed by SFAS No. 123 had been applied by the Company, the effect on net income and earnings per share for the three and six months ended July 3, 2005 would have been as follows:

As of July 2, 2006, the Company had three stock-based compensation plans. Under the 2005 Incentive Plan, 5.4 million shares of the Company’s common stock were made available for option grants, restricted stock awards and performance units. Under the 2001 Incentive Plan, 8.8 million shares of the Company’s common stock were made available for option grants, restricted stock awards and performance units. Under the Life Sciences Plan, 2.3 million shares of the Company’s common stock were made available for option grants.

For the three and six months ended July 2, 2006, in accordance with the adoption of SFAS No. 123(R), the Company recorded incremental stock-based compensation expense of $2.1 million and $3.8 million, respectively. The total stock-based compensation expense for the cost of stock options, restricted stock, restricted stock units and performance units was $3.5 million and $6.3 million for the three and six months ended July 2, 2006, respectively. The total stock-based compensation expense has been included in the Consolidated Statements of Income, primarily as part of selling, general and administrative expenses. The total income tax benefit recognized in the Consolidated Statements of Income for stock-based compensation was $1.2 million and $2.1 million for the three and six months ended July 2, 2006, respectively. Stock-based compensation costs capitalized as part of inventory were approximately $0.5 million as of July 2, 2006.

Stock Options: Options are granted to purchase common shares at prices equal to the market price of the common shares on the date the option is granted. Conditions of vesting are determined at the time of grant. Options are generally exercisable in equal annual installments over a period of three years and will generally expire seven years after the date of grant. Options assumed as part of business combination transactions retain all the rights, terms and conditions of the respective plans under which they were originally issued.

The fair value of each option grant is estimated using the Black-Scholes option pricing model. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with

respect to selected model inputs. Expected volatility was calculated primarily based on the historical volatility of the Company’s stock. The average expected life was based on the contractual term of the option and historic exercise experience. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. Forfeitures are estimated based on voluntary termination behavior, as well as an analysis of actual option forfeitures. The Company’s weighted-average assumptions used in the Black-Scholes option pricing model are as follows:

A summary of option activity as of July 2, 2006 and changes during the six months then ended is presented below:

The weighted-average grant-date fair values of options granted for the three and six months ended July 2, 2006 were $6.90 and $6.86, respectively. The weighted-average grant-date fair values of options granted for the three and six months ended July 3, 2005 were $7.16 and $8.21, respectively. The total intrinsic value of options exercised for the three and six months ended July 2, 2006 were $1.6 million and $15.0 million, respectively. The total intrinsic value of options exercised for the three and six months ended July 3, 2005 were $0.9 million and $3.4 million, respectively.

Cash received from option exercises for the first six months of 2006 and the first six months of 2005 was $17.1 million and $4.0 million, respectively. The related tax benefit classified as a financing cash inflow was $3.6 million for the six months ended July 2, 2006.

The total compensation recognized related to the stock options, which is a function of current and prior year awards, is net of estimated forfeitures and was approximately $2.1 million and $3.8 million for the three and six months ended July 2, 2006, respectively. There was $15.2 million of total unrecognized compensation cost related to non-vested stock options granted as of July 2, 2006. This cost is expected to be recognized over a weighted-average period of 1.9 fiscal years and will be adjusted for any future changes in estimated forfeitures. The following table summarizes total compensation expense related to stock options included in the Company’s condensed consolidated statement of operations:

The following table summarizes information about stock options outstanding as of July 2, 2006:

Restricted Stock Awards: The Company has awarded restricted stock and restricted stock units that contain time-based vesting provisions and restricted stock that contains performance-based vesting provisions to certain employees at no cost to them, which cannot be sold, assigned, transferred or pledged during the restriction period. These shares were awarded under the Company’s 2005 Incentive Plan and 2001 Incentive Plan. All restrictions on the awards will lapse upon certain situations including death or disability of the employee and a change in control of the Company. Recipients of the restricted stock have the right to vote such shares and receive dividends, whereas the recipients of restricted stock units do not have these same benefits.

Restricted Stock Awards (Time-based Vesting)—Grants of restricted stock and restricted stock units that vest through the passage of time. The fair value of the award at the time of the grant is expensed on a straight line basis primarily in selling, general and administrative expenses over the vesting period, which is generally three years.

Restricted Stock Awards (Performance–based Vesting)—Grants of restricted stock that vest based on certain specified performance criteria. The fair value of the shares is expensed over the period of performance primarily in selling, general and administrative expenses, once achievement of criteria is deemed probable.

A summary of the status of the Company’s restricted stock awards as of July 2, 2006 and changes during the six months then ended are presented below:

The weighted-average grant-date fair values of restricted stock awards granted during the three and six months ended July 2, 2006 were $20.65 and $22.78, respectively. The weighted-average grant-date fair values of restricted stock awards granted during the three and six months ended July 3, 2005 were $18.23 and $20.88, respectively. The total compensation recognized related to the restricted stock awards, which is a function of current and prior year awards, was approximately $0.8 million and $1.4 million for the three and six months ended July 2, 2006. As of July 2, 2006, there were 546,163 shares of restricted stock awards outstanding subject to forfeiture.

As of July 2, 2006, there was $9.5 million of total unrecognized compensation cost related to nonvested restricted stock awards. That cost is expected to be recognized over a weighted-average period of 2.0 fiscal years. The fair value of restricted stock awards vested during the first six months of 2006 was $0.1 million. There were no restricted stock awards that vested during the first six months of 2005.

Unearned compensation is recorded in a contra-equity account and established at the date restricted stock is granted representing the amount of unrecognized restricted stock expense that is reduced as expense is recognized. Under the provisions of SFAS No. 123(R), the recognition of unearned compensation at the date restricted stock is granted is no longer required. Therefore, in the first quarter of 2006, the $6.4 million of unrecognized restricted stock that had been in “Unearned compensation” in the Condensed Consolidated Balance Sheet as of January 1, 2006 was reversed to “Capital in excess of par value.”

Performance Units: The performance unit program provides a cash award based on the achievement of specific performance criteria. A target number of units are granted at the beginning of a three-year performance period. The number of units earned at the end of the performance period is determined by multiplying the number of units granted by a performance factor for each individual ranging from 0% to 200%. Awards are determined by multiplying the number of units earned by the stock price at the end of the performance period and are paid in cash. The compensation expense associated with these units is recognized over the period that the performance targets are expected to be achieved. The Company granted 208,328 and 247,197 performance units in the first six months of 2006 and the first six months of 2005, respectively. The weighted-average grant-date fair values of performance units granted during the first six months of 2006 and the first six months of 2005 were $22.74 and $21.02, respectively. The total compensation related to these performance units, which is a function of current and prior year awards, was approximately $0.6 million and $1.1 million for the three and six months ended July 2, 2006, respectively. As of July 2, 2006, there were 546,995 performance units outstanding subject to forfeiture.

Employee Stock Purchase Plan: In April 1999, the Company’s stockholders approved the 1998 Employee Stock Purchase Plan, whereby participating employees had the right to purchase common stock at a price equal to 85% of the lower of the closing price on the first day or the last day of the six-month offering period. In April 2005, the Compensation and Benefits Committee of PerkinElmer’s Board of Directors voted to amend the Employee Stock Purchase Plan, effective July 1, 2005, whereby participating employees have the right to purchase common stock at a price equal to 95% of the closing price on the last day of each six-month offering period. The number of shares which an employee may purchase, subject to certain aggregate limits, is determined by the employee’s voluntary contribution, which may not exceed 10% of the employee’s base compensation.

During the six months ended July 2, 2006, the Company issued 0.1 million shares under this plan at a weighted-average price of $19.85 per share. There remains available for sale to employees an aggregate of 1.8 million shares of the Company’s stock out of the 5.0 million shares authorized by shareholders.

Stock Repurchase Program: In the first six months of 2006, the Company repurchased in the open market 5.0 million shares of its common stock at an aggregate cost of $116.4 million, including commissions. Such shares repurchased have been reflected as additional authorized but unissued shares, with the payments reflected in common stock and capital in excess of par value. These repurchases were made pursuant to the Company’s stock repurchase program (the “Program”) which authorizes repurchases of up to an aggregate of 10.0 million shares of the Company’s common stock. Subsequent to the quarter ended July 2, 2006, the Company repurchased approximately 2.2 million shares of its common stock in the open market under the Program at an aggregate cost of approximately $41.3 million, including commissions, leaving the Company with remaining authorization under the Program to repurchase up to approximately 1.7 million shares in the future.

In accordance with SFAS No. 142, “Goodwill and other Intangible Assets,” the Company is required to test goodwill for impairment at the reporting unit level upon initial adoption and at least annually thereafter. As part of the Company’s on-going compliance with SFAS No. 142, the Company, assisted by valuation consultants, completed its annual assessment of goodwill using a measurement date of January 2, 2006. The results of this annual assessment resulted in no impairment charge.

The changes in the carrying amount of goodwill for the period ended July 2, 2006 from January 1, 2006 are as follows:

The Company provides warranty protection for certain products for periods ranging from one to three years beyond the date of sale. The majority of costs associated with warranty obligations include the replacement of parts and the time of service personnel to respond to repair and replacement requests. A warranty reserve is recorded based upon historical results, supplemented by management’s expectations of future costs. Warranty reserves are included in “Accrued expenses” on the Condensed Consolidated Balance Sheets. A summary of warranty reserve activity for the three and six months ended July 2, 2006 and July 3, 2005 is as follows:

The following table summarizes the components of net periodic benefit cost (credit) for the Company’s various defined benefit employee pension and post-retirement plans in accordance with SFAS No. 132 (revised 2003), “Employers’ Disclosures about Pensions and Other Postretirement Benefits,” for the three and six months ended July 2, 2006 and July 3, 2005:

The Company is conducting a number of environmental investigations and remedial actions at current and former Company locations and, along with other companies, has been named a potentially responsible party

(“PRP”) for certain waste disposal sites. The Company accrues for environmental issues in the accounting period that the Company’s responsibility is established and when the cost can be reasonably estimated. The Company has accrued $3.5 million as of July 2, 2006, representing management’s estimate of the total cost of ultimate disposition of known environmental matters. Such amount is not discounted and does not reflect the recovery of any amounts through insurance or indemnification arrangements. These cost estimates are subject to a number of variables, including the stage of the environmental investigations, the magnitude of the possible contamination, the nature of the potential remedies, possible joint and several liability, the time period over which remediation may occur and the possible effects of changing laws and regulations. For sites where the Company has been named a PRP, management does not currently anticipate any additional liability to result from the inability of other significant named parties to contribute. The Company expects that such accrued amounts could be paid out over a period of up to ten years. As assessment and remediation activities progress at each individual site, these liabilities are reviewed and adjusted to reflect additional information as it becomes available. There have been no environmental problems to date that have had or are expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.

In papers dated October 23, 2002, Enzo Biochem, Inc. and Enzo Life Sciences, Inc. (collectively, “Enzo”) filed a complaint in the United States District Court for the Southern District of New York, Civil Action No. 02-8448, against Amersham plc, Amersham BioSciences, PerkinElmer, Inc., PerkinElmer Life Sciences, Inc., Sigma-Aldrich Corporation, Sigma Chemical Company, Inc., Molecular Probes, Inc., and Orchid BioSciences, Inc. The complaint alleges that the Company has breached its distributorship and settlement agreements with Enzo, infringed Enzo’s patents, engaged in unfair competition and fraud, and committed torts against Enzo by, among other things, engaging in commercial development and exploitation of Enzo’s patented products and technology, separately and together with the other defendants. Enzo seeks injunctive and monetary relief. In 2003, the court severed the lawsuit and ordered Enzo to serve individual complaints against the five defendants. The Company subsequently filed an answer and a counterclaim alleging that Enzo’s patents are invalid. On July 17, 2006, the court issued a decision regarding the construction of the claims in Enzo’s patents that effectively limited the coverage of certain of those claims and, the Company believes, excludes certain of the Company’s products from the coverage of Enzo’s patents. Discovery is ongoing and the court has not set a date for trial.

On October 17, 2003, Amersham Biosciences Corp. filed a complaint, which was subsequently amended, in the United States District Court for New Jersey, Civil Action No. 03-4901, against a subsidiary of the Company, alleging that the Company’s ViewLux^™ and certain of its Image FlashPlate^™ products infringe three of Amersham’s patents related to high-throughput screening (the “NJ case”). On August 18, 2004, Amersham plc filed a complaint against two of the Company’s United Kingdom-based subsidiaries in the Patent Court of the English High Court of Justice, Case No. 04C02688, alleging that the Company’s same products infringe one corresponding Amersham patent in the United Kingdom, which was granted in August 2004 (the “UK case”). Amersham seeks injunctive and monetary relief in both cases. The Company filed answers and counterclaims in both cases. On October 29, 2003, the Company filed a complaint, which was subsequently amended, against Amersham in the United States District Court for Massachusetts, Civil Action No. 03-12098, alleging that Amersham’s IN Cell Analyzer, and LEADseeker^™ Multimodality Imaging system and certain Cyclic AMP and IP3 assays infringe two of the Company’s patents related to high-throughput screening (the “MA case”). The Company seeks injunctive and monetary relief. Amersham subsequently filed an answer and counterclaims. After a trial in the UK case in December 2005, the court ruled in February 2006 that Amersham’s patent in question was invalid in the United Kingdom and awarded costs to the Company. Amersham’s appeal of the ruling in the UK case is scheduled to be heard in early 2007. On May 23, 2006, the court in the NJ case issued a decision regarding the construction of the claims in Amersham’s patents that adopted many of Amersham’s claim construction positions. The company has filed a motion asking the court to reconsider that decision. Discovery has not yet been completed in either the NJ or MA case, nor has a trial date been set in either case. Proceedings in the NJ and MA cases have been stayed while the parties pursue voluntary mediation efforts.

The Company believes it has meritorious defenses to these lawsuits and other proceedings, and it is contesting the actions vigorously in all of the above matters. The Company is currently unable, however, to

reasonably estimate the amount of loss, if any, that may result from the resolution of these matters or to determine whether resolution of any of these matters will have a material adverse impact on its consolidated financial statements.

During 2005, the Internal Revenue Service concluded its audit of federal income taxes for the years 1999 through 2002. The Company has agreed to the conclusions of the Internal Revenue Service in all matters with the exception of one, and has filed a single issue protest with the Appeals Division of the Internal Revenue Service, and expects to resolve the matter in 2006. Regardless of the outcome of this matter, the Company does not expect the final resolution to significantly impact its financial position, results of operations or cash flows in 2006.

The Company is under regular examination by tax authorities in the United States and other countries in which the Company has significant business operations. The tax years under examination vary by jurisdiction. The Company regularly assesses the likelihood of additional assessments in each of the taxing jurisdictions resulting from these and subsequent years’ examinations. The Company has established income tax reserves which it believes to be adequate in relation to the potential for additional assessments. Once established, reserves are adjusted as information becomes available and when an event occurs requiring a change to the reserves. The resolution of tax matters is not expected to have a material effect on the Company’s consolidated financial condition, although such settlement could have a material impact on its effective tax rate, consolidated statement of income and consolidated statement of cash flows for a particular future period.

The Company is also subject to various other claims, legal proceedings and investigations covering a wide range of matters that arise in the ordinary course of its business activities. Each of these matters is subject to uncertainties, and it is possible that some of these matters may be resolved unfavorably to the Company. The Company has established accruals for potential losses that it believes are probable and reasonably estimable. In the opinion of the Company’s management, based on its review of the information available at this time, the total cost of resolving these other contingencies at July 2, 2006, should not have a material adverse effect on the Company’s consolidated financial statements.

This quarterly report on Form 10-Q, including the following management’s discussion and analysis, contains forward-looking information that you should read in conjunction with the condensed consolidated financial statements and notes to the condensed consolidated financial statements that we have included elsewhere in this quarterly report on Form 10-Q. For this purpose, any statements contained in this report that are not statements of historical fact may be deemed to be forward-looking statements. Words such as “believes,” “plans,” “anticipates,” “expects,” “will” and similar expressions are intended to identify forward-looking statements. Our actual results may differ materially from the plans, intentions or expectations we disclose in the forward-looking statements we make. We have included important factors under the heading “Risk Factors” in Item 1A below that we believe could cause actual results to differ materially from the forward-looking statements we make. We are not obligated to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.

We are a leading provider of scientific instruments, consumables and services to the pharmaceutical, biomedical, academic research, environmental testing and general industrial markets, commonly referred to as the health sciences and photonics markets. We design, manufacture, market and service products and systems within two businesses, each constituting a separate reporting segment:

The health sciences markets include all of the businesses in our Life and Analytical Sciences reporting segment and the medical imaging business, as well as elements of the medical sensors and lighting businesses in our Optoelectronics reporting segment. The photonics markets include the remaining businesses in our Optoelectronics reporting segment.

Divestiture of Fluid Sciences Semiconductor Business. In February 2006, we sold substantially all of the assets of our Fluid Sciences Semiconductor business to an entity affiliated with Tara Capital, Inc. for approximately $26.5 million (subject to a net working capital adjustment) plus potential additional contingent consideration. We recognized a pre-tax gain of $3.7 million, exclusive of additional contingent consideration, in the first six months of 2006.

Acquisition of Agilix Corporation. In February 2006, we acquired certain assets of Agilix Corporation (“Agilix”) for approximately $8.7 million in cash plus potential additional contingent consideration, which we expect to be immaterial to the Company. Assets acquired primarily relate to Agilix’s core technology which centers around labeling technology using isobaric mass tags that allows for the simultaneous quantification of molecules, such as proteins, from multiple samples. Agilix’s operations are reported within the results of our Life and Analytical Sciences segment from the acquisition date. This acquisition did not have a material effect on our financial position, results of operations or cash flows.

Acquisition of Spectral Genomics, Inc. In April 2006, we acquired certain assets and liabilities of Spectral Genomics, Inc. (“Spectral”), a leader in molecular karyotyping technology used to evaluate chromosomal abnormalities. Consideration for the transaction was approximately $12.0 million in cash plus potential additional contingent consideration, which we expect to be immaterial to the Company. Spectral’s operations are reported within the results of our Life and Analytical Sciences segment from the acquisition date. This acquisition did not have a material effect on our financial position, results of operations or cash flows.

Acquisition of Clinical & Analytical Service Solutions Ltd. In June 2006, we acquired the stock of Clinical & Analytical Service Solutions Ltd. (“C&A”), a scientific equipment asset and managed maintenance company serving the pharmaceutical, biotechnology and healthcare markets. Consideration for the transaction was approximately $12.3 million in cash plus potential additional contingent consideration, which we expect to be immaterial to the Company. C&A’s operations are reported within the results of our Life and Analytical Sciences segment from the acquisition date. This acquisition did not have a material effect on our financial position, results of operations or cash flows.

Restructuring. During the second quarter of 2006, our management approved a plan to terminate employees in two locations in the U.S. as we shift resources into product lines that are more consistent with our growth strategy. The actions within the Q2 2006 Plan, described below, related to a workforce reduction resulting from reorganization activities within the Life and Analytical Sciences business. We completed notifying affected employees on June 30, 2006. As a result of this plan of termination, we recorded a pre-tax restructuring charge of $0.8 million during the second quarter of 2006 (the “Q2 2006 Plan”). Substantially all of this pre-tax restructuring charge will result in future cash expenditures which we expect will be paid by the end of 2006.

Acquisition of J.N. Macri Technologies LLC and NTD Laboratories, Inc. Subsequent to the quarter ended July 2, 2006, we acquired certain assets and liabilities of J.N. Macri Technologies LLC (“Macri”) and the stock of NTD Laboratories, Inc. (“NTD”). Macri holds and licenses global patents related to free beta Human Chorionic Gonadotropin (“free Beta hCG”). Free Beta hCG is a peptide hormone produced in the early stage of pregnancy that is widely recognized as an important biomarker for first-trimester prenatal risk assessment. NTD is a laboratory specializing in prenatal risk assessment and offers laboratory developed and validated testing under the brand name UltraScreen^®, of which free Beta hCG is an important component. Aggregate consideration for these transactions was $56.65 million in cash, subject to a net working capital adjustment. Both the Macri and NTD operations will be reported within the results of our Life and Analytical Sciences segment from the acquisition date

Stock Repurchase Program. In the first six months of 2006, we repurchased in the open market 5.0 million shares of our common stock at an aggregate cost of $116.4 million, including commissions. Such shares repurchased have been reflected as additional authorized but unissued shares, with the payments reflected in common stock and capital in excess of par value. These repurchases were made pursuant to our stock repurchase program (the “Program”) which authorizes repurchases of up to an aggregate of 10.0 million shares of our common stock. Subsequent to the quarter ended July 2, 2006, we repurchased approximately 2.2 million shares of our common stock in the open market under the Program at an aggregate cost of approximately $41.3 million, including commissions, leaving us with remaining authorization under the Program to repurchase up to approximately 1.7 million shares in the future.

The preparation of consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, sales and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to bad debts, inventories, intangible assets, income taxes, restructuring, pensions and other post-retirement benefits, stock-based compensation, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting policies are those policies that affect our more significant judgments and estimates used in preparation of our consolidated financial statements. We believe our critical accounting policies include our policies regarding revenue recognition, allowances for doubtful accounts, inventory valuation, value of long-lived assets, including intangibles, employee compensation and benefits, restructuring activities, gains or losses

on dispositions and income taxes. For a more detailed discussion of our critical accounting policies, please refer to our annual report on Form 10-K for the fiscal year ended January 1, 2006, filed with the Securities and Exchange Commission (the “2005 Form 10-K”).

Sales for the second quarter of 2006 were $377.0 million, versus $368.0 million for the second quarter of 2005, an increase of $9.0 million, or 2%. The effect of acquisitions increased our second quarter of 2006 sales by $1.6 million. Changes in foreign exchange rates had an immaterial impact on sales in the second quarter of 2006, as compared to the second quarter of 2005. This increase in sales reflects a $7.7 million, or 3%, increase in our Life and Analytical Sciences segment sales and an increase of $1.3 million, or 1%, in our Optoelectronics segment sales.

Sales for the six-month period ended July 2, 2006 were $732.5 million, versus $726.2 million for the six-month period ended July 3, 2005, an increase of $6.3 million, or 1%. The effect of acquisitions increased our sales for the six-month period ended July 2, 2006 by $3.0 million. Changes in foreign exchange rates, primarily the Euro, decreased sales by approximately $8.5 million in the six-month period ended July 2, 2006, as compared to the six-month period ended July 3, 2005. This increase in sales reflects a $4.8 million, or 1%, increase in our Life and Analytical Sciences segment sales, which includes an approximately $6.9 million decrease in sales attributable to unfavorable changes in foreign exchange rates compared to the six-month period ended July 3, 2005 as well as $2.4 million from acquisitions. Our Optoelectronics segment sales grew $1.4 million, or 1%, including an approximately $1.6 million decrease in sales attributable to unfavorable changes in foreign exchange rates compared to the six-month period ended July 3, 2005.

Cost of sales for the second quarter of 2006 was $225.4 million, versus $216.9 million for the second quarter of 2005, an increase of $8.5 million, or 4%. As a percentage of sales, cost of sales increased to 59.8% in the second quarter of 2006 from 58.9% in the second quarter of 2005, resulting in a decrease in gross margin of 90 basis points from 41.1% in the second quarter of 2005 to 40.2% in the second quarter of 2006. The decrease in gross margin percentage was primarily attributable to commodity costs, as well as slightly unfavorable product and geography mix. Cost of sales for the second quarter of 2006 included $0.3 million of stock option expense.

Cost of sales for the six-month period ended July 2, 2006 was $439.2 million, versus $426.8 million for the six-month period ended July 3, 2005, an increase of $12.4 million, or 3%. As a percentage of sales, cost of sales increased to 60.0% in the six-month period ended July 2, 2006 from 58.8% in the six-month period ended July 3, 2005, resulting in a decrease in gross margin of 120 basis points from 41.2% in the six-month period ended July 3, 2005, to 40.0% in the six-month period ended July 2, 2006. The decrease in gross margin percentage was attributable to capacity issues and a shift in customer mix within the amorphous silicon business, commodity costs, as well as slightly unfavorable product and geography mix. Cost of sales for the six-month period ended July 2, 2006 included $0.3 million of stock option expense.

Selling, general and administrative expenses for the second quarter of 2006 were unchanged at $92.7 million from the second quarter of 2005. As a percentage of sales, selling, general and administrative expenses decreased 60 basis points from 25.2% in the second quarter of 2005 to 24.6% in the second quarter of 2006. The decrease as a percentage of sales of 60 basis points in the second quarter of 2006, as compared to the second quarter of 2005, was primarily the result of increased fixed cost leverage and cost controls offset in part by increased investment in business development activities and an increase in the number of sales employees in both emerging

markets and higher growth product lines. Selling, general and administrative expenses for the second quarter of 2006 included $1.6 million of stock option expense.

Selling, general and administrative expenses for the six-month period ended July 2, 2006 were $182.5 million versus $189.5 million for the six-month period ended July 3, 2005, a decrease of $7.0 million, or 4%. As a percentage of sales, selling, general and administrative expenses decreased 120 basis points from 26.1% in the six-month period ended July 3, 2005 to 24.9% in the six-month period ended July 2, 2006. The decrease as a percentage of sales of 120 basis points in the six-month period ended July 2, 2006, as compared to the six-month period ended July 3, 2005, was the result of increased fixed cost leverage and cost controls offset in part by increased investment in business development activities and an increase in the number of sales employees in both emerging markets and higher growth product lines. Selling, general and administrative expenses for the six-moth period ended July 2, 2006 included $3.1 million of stock option expense.

Research and development expenses for the second quarter of 2006 were $25.0 million versus $22.1 million for the second quarter of 2005, an increase of $3.0 million, or 13%. As a percentage of sales, research and development expenses increased 60 basis points from 6.0% in the second quarter of 2005 to 6.6% in the second quarter of 2006. We expect our research and development efforts to increase and continue to emphasize the health sciences end markets in order to help accelerate our growth initiative. Research and development expenses for the second quarter of 2006 included $0.2 million of stock option expense.

Research and development expenses for the six-month period ended July 2, 2006 were $47.9 million versus $44.7 million for the six-month period ended July 3, 2005, an increase of $3.2 million, or 7%. As a percentage of sales, research and development expenses increased to 6.5% in the six-month period ended July 2, 2006, from 6.2% in the six-month period ended July 3, 2005. Research and development expenses for the six-month period ended July 2, 2006 included $0.4 million of stock option expense.

We have undertaken a series of restructuring actions related to the impact of acquisitions, divestitures and the integration of its business units. Restructuring actions were recorded in accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.” In certain instances, specifically when governmental authorities are involved in setting severance levels, SFAS No. 112, “Employers’ Accounting for Postemployment Benefits,” is applied. The principal actions associated with these plans related to workforce reductions and overhead reductions resulting from reorganization activities, including the closure of certain manufacturing and selling facilities. Details of these plans are discussed more fully in our 2005 Form 10-K.

On June 28, 2006, our management approved a plan to terminate employees in two locations in the U.S. as we shift resources into product lines that are more consistent with our growth strategy. We completed notifying affected employees on June 30, 2006. As a result of this plan of termination, we recorded a pre-tax restructuring charge of $0.8 million during the second quarter of 2006 (the “Q2 2006 Plan”). The actions within the Q2 2006 Plan related to a workforce reduction resulting from reorganization activities within the Life and Analytical Sciences business.

In addition, during the second quarter of 2006, we recorded a pre-tax restructuring charge of $0.4 million relating to our restructuring plan in the fourth quarter of 2005 (the “Q4 2005 Plan”) due to higher than expected costs associated with the termination of employees in Europe within our Life and Analytical Sciences segment. We also recorded a pre-tax restructuring reversal of $1.4 million relating to our Q4 2005 restructuring plan due to the completion in June 2006 of the sale of a building previously reserved for in the Q4 2005 Plan. The amount of the proceeds from this sale in excess of the current book value of the property was recorded as a restructuring reversal within our Optoelectronics segment. A description of each of the restructuring plans and the activity recorded for the six month period ended July 2, 2006 is as follows:

During the second quarter of 2006, we recognized a $0.8 million restructuring charge in the Life and Analytical Sciences segment. The purpose of this restructuring action was to shift resources into product lines that were more consistent with our growth strategy. The actions in the Q2 2006 Plan were headcount reductions resulting from reorganization activities.

The following table summarizes the components of the Q2 2006 Plan activity for the six months ended July 2, 2006:

All actions related to the Q2 2006 Plan were completed by the end of the second quarter of 2006, and we anticipate that all payments will be completed by the end of 2006.

During the fourth quarter of 2005, we recognized a $2.2 million restructuring charge in the Life and Analytical Sciences business and a $6.0 million restructuring charge in the Optoelectronics business, which we refer to as the Q4 2005 Plan. The purpose of these restructuring actions was to shift resources into geographic regions and product lines that were more consistent with our growth strategy. The principal actions in the Q4 2005 Plan were headcount reductions and the closure of several facilities resulting from reorganization activities.

In addition, during the second quarter of 2006, we recorded a pre-tax restructuring charge of $0.4 million relating to our Q4 2005 restructuring plan due to higher than expected costs associated with the termination of employees in Europe within our Life and Analytical Sciences segment. We also recorded a pre-tax restructuring reversal of $1.4 million relating to our Q4 2005 restructuring plan due to the completion in June 2006 of the sale of a building previously reserved for in the Q4 2005 Plan. The amount of the proceeds from this sale in excess of the current book value of the property was recorded as a restructuring reversal within our Optoelectronics segment.

The following table summarizes the components of the Q4 2005 Plan activity for the six months ended July 2, 2006:

All actions related to the Q4 2005 Plan have been completed and we anticipate that all payments will be completed by the end of 2006.

During the second quarter of 2005, we recognized a $5.3 million restructuring charge in the Life and Analytical Sciences business and a $2.9 million restructuring charge in the Optoelectronics business, which we refer to as the Q2 2005 Plan. The purpose of these restructuring actions was to shift resources into geographic regions and product lines that were more consistent with our growth strategy. The principal actions in the Q2 2005 Plan comprised headcount reductions resulting from reorganization activities.

The following table summarizes the components of the Q2 2005 Plan activity for the six months ended July 2, 2006:

All actions related to the Q2 2005 Plan have been completed and we anticipate that payments will be completed by the end of 2006.

We have approximately $6.5 million of remaining liabilities associated with 2001 to 2003 restructuring and integration plans, primarily relating to remaining lease obligations of closed facilities. The remaining terms of these leases vary in length but all will be completed by 2014.

Interest and other expense, net for the three months ended July 2, 2006 was $1.8 million, versus $7.4 million for the three months ended July 3, 2005, a decrease of $5.6 million or 76%. The decrease in interest and other expense, net in the second quarter of 2006 as compared to the second quarter of 2005 was primarily due to the overall reduction in outstanding debt, and the increase in outstanding cash balances. Interest expense decreased $5.3 million primarily due to the $300.0 million of principal payments made on our senior subordinated 8⁷/8% notes which we repurchased through a tender offer in the fourth quarter of 2005. These debt reductions in 2005 were partially offset by $199.0 million in new debt outstanding as of July 2, 2006 against our new senior unsecured credit facility, which we entered into on October 31, 2005. In addition, interest income increased $1.7 million due to higher cash balances and higher investment rates. We also recognized a gain on sale of investments of $0.7 million associated with the liquidation of an investment. Other expenses consisted primarily of expense related to foreign currency translation, and deal costs for unconsummated deals. For the six months ended July 2, 2006, interest and other expense, net was $1.6 million versus $15.5 million for the comparable period in 2005, a decrease of $13.9 million, or 89%. The decrease primarily relates to the lower average outstanding balances on the senior subordinated 8⁷/8% Notes which we repurchased through a tender offer in the fourth quarter of 2005. A discussion of our liquidity and our prospective borrowing costs is set forth below under the heading “Liquidity and Capital Resources.”

Subsequent to the quarter ended July 2, 2006, we received $2.9 million related to the liquidation of an investment, which will be recognized as a gain on sale of investments during the third quarter of 2006.

The second quarter 2006 provision for income taxes was $7.6 million, versus a benefit of $16.3 million for the second quarter of 2005. The provision for income taxes was $14.7 million for the six-month period ended July 2, 2006, compared to a benefit from income taxes of $11.3 million for the six-month period ended July 3, 2005.

During the second quarter of 2006 and the second quarter of 2005, our continuing operations tax provisions were reduced, in aggregate, by discrete items totaling approximately $0.7 million and $19.9 million, respectively.

The reported provision for income taxes for the second quarter of 2006 was reduced by a benefit from the settlement of income tax audits of $0.7 million, resulting in a provision before the effect of discrete items of $8.3 million. The reported provision for income taxes for the six months ended July 2, 2006 was reduced by a benefit from the settlement of income tax audits of $0.7 million, resulting in a provision before the effect of discrete items of $15.4 million. The reported benefit from income taxes for the second quarter of 2005 was reduced by discrete items of $19.9 million including a benefit from the settlement of income tax audits of $26.5 million partially offset by a provision of $6.6 million for the U.S. tax cost on $225.0 million of earnings to be repatriated in accordance with the Homeland Investment provisions of the American Jobs Creation Act of 2004 (“HIA”), and IRS clarification of the U.S. tax calculation related to repatriated earnings. The 2005 second quarter tax provision before the effect of discrete items was $3.6 million. The reported benefit from income taxes for the six months ended July 3, 2005 was affected by a benefit from the settlement of income tax audits of $26.5 million and the provision for HIA repatriated earnings of $6.6 million, resulting in a provision before the effect of discrete items of $8.6 million.

Without the impact of these second quarter discrete items, our continuing operations effective tax rate for the second quarter of 2006 and six months ended July 2, 2006 was 24.5%. The comparable effective tax rates for the second quarter of 2005 and six months ended July 3, 2005 were 25.1% and 24.7%, respectively.

The lower continuing operations effective tax rate before discrete items for the first half of 2006 is due mainly to our geographic pattern of earnings.

We believe that the inclusion of these non-GAAP financial measures helps investors to gain a meaningful understanding of our tax provision and effective tax rate and their effect on our core operating results and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts. Our management uses these non-GAAP measures, in addition to GAAP financial measures, as the basis for measuring our tax provision and effective tax rate and their effect on our core operating results and future prospects and comparing such performance to that of prior periods and to the performance of our competitors. These measures are also used by management in their financial and operating decision making.

As part of our continued efforts to focus on higher growth opportunities, we have discontinued certain businesses and accounted for them as discontinued operations in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” Accordingly, the results of operations and related cash flows have been presented as discontinued operations for all periods presented. The assets and liabilities of these businesses have been presented separately and are reflected within the assets and liabilities from discontinued operations in the accompanying balance sheets as of July 2, 2006 and January 1, 2006.

In September 2005, our Board of Directors approved a plan to divest our Fluid Sciences segment. The Fluid Sciences segment consisted of three businesses—Aerospace, Fluid Testing and Semiconductor. In November 2005, we sold the Fluid Testing division to Caleb Brett USA Inc. for approximately $34.5 million, resulting in a net pre-tax gain of $30.3 million. In December 2005, we sold the Aerospace division to Eaton Corporation for

approximately $333.0 million, resulting in a net pre-tax gain of $250.6 million. These gains were recognized during fiscal 2005 as gains on the disposition of discontinued operations. We received total cash proceeds in these transactions of approximately $361.1 million. During the first six months of 2006, we finalized the net working capital adjustments associated with the sales of these businesses and settled a claim related to an employee benefit program, resulting in the recognition of losses of $1.3 million and $0.2 million relative to the Aerospace business and the Fluid Testing business, respectively. On February 27, 2006, we sold substantially all of the assets of our Semiconductor business for approximately $26.5 million (subject to a net working capital adjustment) plus potential additional contingent consideration. The pre-tax gain of $3.7 million, exclusive of additional contingent consideration, was recognized in the first six months of 2006.

In June 2005, our Board of Directors approved a plan to shut down our Fiber Optics Test Equipment business. In December 2005, our Board of Directors approved a plan to sell our Lithography business. The results of these businesses were previously reported as part of the Optoelectronics reporting segment. The completion of the shut-down of the Fiber Optics Test Equipment business resulted in a pre-tax loss of $5.2 million related to lease and severance costs and the reduction of fixed assets and inventory to net realizable value. We recognized the net loss during fiscal 2005.

During 2006 and 2005, we settled various claims under certain long-term contracts and transition services with our Technical Services business, which was sold in August of 1999.

The table below summarizes the gains and losses on dispositions of discontinued operations, as discussed above:

We are conducting a number of environmental investigations and remedial actions at our current and former locations and, along with other companies, have been named a potentially responsible party (“PRP”) for certain waste disposal sites. We accrue for environmental issues in the accounting period that our responsibility is established and when the cost can be reasonably estimated. We have accrued $3.5 million as of July 2, 2006, representing our management’s estimate of the total cost of ultimate disposition of known environmental matters. This amount is not discounted and does not reflect any recovery of any amounts through insurance or indemnification arrangements. These cost estimates are subject to a number of variables, including the stage of the environmental investigations, the magnitude of the possible contamination, the nature of the potential remedies, possible joint and several liability, the time period over which remediation may occur, and the possible effects of changing laws and regulations. For sites where we have been named a PRP, our management does not currently anticipate any additional liability to result from the inability of other significant named parties to contribute. We expect that such accrued amounts could be paid out over a period of up to ten years. As assessment and remediation activities progress at each individual site, these liabilities are reviewed and adjusted to reflect additional information as it becomes available. There have been no environmental problems to date that have had or are expected to have a material adverse effect on our financial position, results of operations or cash flows.

In papers dated October 23, 2002, Enzo Biochem, Inc. and Enzo Life Sciences, Inc. (collectively, “Enzo”) filed a complaint in the United States District Court for the Southern District of New York, Civil Action No. 02-8448, against Amersham plc, Amersham BioSciences, PerkinElmer, Inc., PerkinElmer Life Sciences, Inc., Sigma-Aldrich Corporation, Sigma Chemical Company, Inc., Molecular Probes, Inc., and Orchid BioSciences, Inc. The complaint alleges that we have breached our distributorship and settlement agreements with Enzo, infringed Enzo’s patents, engaged in unfair competition and fraud, and committed torts against Enzo by, among other things, engaging in commercial development and exploitation of Enzo’s patented products and technology, separately and together with the other defendants. Enzo seeks injunctive and monetary relief. In 2003, the court severed the lawsuit and ordered Enzo to serve individual complaints against the five defendants. We subsequently filed an answer and a counterclaim alleging that Enzo’s patents are invalid. On July 17, 2006, the court issued a decision regarding the construction of the claims in Enzo’s patents that effectively limited the coverage of certain of those claims and, we believe, excludes certain of our products from the coverage of Enzo’s patents. Discovery is ongoing and the court has not set a date for trial.

high-throughput screening (the “NJ case”). On August 18, 2004, Amersham plc filed a complaint against two of our United Kingdom-based subsidiaries in the Patent Court of the English High Court of Justice, Case No. 04C02688, alleging that our same products infringe one corresponding Amersham patent in the United Kingdom, which was granted in August 2004 (the “UK case”). Amersham seeks injunctive and monetary relief in both cases. We filed answers and counterclaims in both cases. On October 29, 2003, we filed a complaint, which was subsequently amended, against Amersham in the United States District Court for Massachusetts, Civil Action No. 03-12098, alleging that Amersham’s IN Cell Analyzer, and LEADseeker^™ Multimodality Imaging system and certain Cyclic AMP and IP3 assays infringe two of our patents related to high-throughput screening (the “MA case”). We seek injunctive and monetary relief. Amersham subsequently filed an answer and counterclaims. After a trial in the UK case in December 2005, the court ruled in February 2006 that Amersham’s patent in question was invalid in the United Kingdom and awarded costs to us. Amersham’s appeal of the ruling in the UK case is scheduled to be heard in early 2007. On May 23, 2006, the court in the NJ case issued a decision regarding the construction of the claims in Amersham’s patents that adopted many of Amersham’s claim construction positions. We have filed a motion asking the court to reconsider that decision. Discovery has not yet been completed in either the NJ or MA case, nor has a trial date been set in either case. Proceedings in the NJ and MA cases have been stayed while the parties pursue voluntary mediation efforts.

We believe we have meritorious defenses to these lawsuits and other proceedings, and we are contesting the actions vigorously in all of the above matters. We are currently unable, however, to reasonably estimate the amount of loss, if any, that may result from the resolution of these matters or to determine whether resolution of any of these matters will have a material adverse impact on our consolidated financial statements.

During 2005, the Internal Revenue Service concluded its audit of federal income taxes for the years 1999 through 2002. We have agreed to the conclusions of the Internal Revenue Service in all matters with the exception of one, and have filed a single issue protest with the Appeals Division of the Internal Revenue Service, and expect to resolve the matter in 2006. Regardless of the outcome of this matter, we do not expect the final resolution to significantly impact our financial position, results of operations or cash flows in 2006.

We are under regular examination by tax authorities in the United States and other countries in which we have significant business operations. The tax years under examination vary by jurisdiction. We regularly assess the likelihood of additional assessments in each of the taxing jurisdictions resulting from these and subsequent years’ examinations. We have established income tax reserves which we believe to be adequate in relation to the potential for additional assessments. Once established, reserves are adjusted as information becomes available and when an event occurs requiring a change to the reserves. The resolution of tax matters is not expected to have a material effect on our consolidated financial condition, although such settlement could have a material impact on our effective tax rate, consolidated statement of income and consolidated statement of cash flows for a particular future period.

We are also subject to various other claims, legal proceedings and investigations covering a wide range of matters that arise in the ordinary course of our business activities. Each of these matters is subject to uncertainties, and it is possible that some of these matters may be resolved unfavorably to us. We have established accruals for potential losses that we believe are probable and reasonably estimable. In the opinion of our management, based on our review of the information available at this time, the total cost of resolving these other contingencies at July 2, 2006, should not have a material adverse effect on our consolidated financial statements.

Sales for the second quarter of 2006 were $278.5 million, versus $270.8 million for the second quarter of 2005, an increase of $7.7 million, or 3%. Changes in foreign exchange rates accounted for an increase in sales of

$0.9 million in the second quarter of 2006, as compared to the second quarter of 2005. Acquisitions increased sales in our second quarter of 2006 by $1.6 million, as compared to the second quarter of 2005. The analysis in the remainder of this paragraph compares selected sales by market and product type for the second quarter of 2006, as compared to the second quarter of 2005, and includes the effect of foreign exchange rate fluctuations and acquisitions. Our OneSource^™ laboratory service sales increased by $5.1 million, sales to genetic screening customers increased $3.5 million, and sales to environmental and chemical analysis customers increased $2.0 million. These increases were offset by decreases in sales to biopharmaceutical customers of $2.9 million. Sales by type of product included increases in service of $5.1 million and instruments of $4.8 million offset by decreases in consumables of $2.2 million.

Sales for the six-month period ended July 2, 2006 were $540.4 million, versus $535.6 million for the six-month period ended July 3, 2005, an increase of $4.8 million, or 1%. The effect of acquisitions increased our sales for the six-month period ended July 2, 2006 by $2.4 million, as compared to the six-month period ended July 3, 2005. Changes in foreign exchange rates, primarily the Euro, decreased sales by approximately $6.9 million in the six-month period ended July 2, 2006, as compared to the six-month period ended July 3, 2005. The following analysis in the remainder of this paragraph compares selected sales by market and product type for the six-month period ended July 2, 2006, as compared to the six-month period ended July 3, 2005, and includes the effect of foreign exchange rate fluctuations and acquisitions. Our OneSource^™ laboratory service sales increased by $8.1 million, sales to genetic screening customers increased by $6.4 million, and sales to environmental and chemical analysis customers increased by $3.8 million, while sales to biopharmaceutical customers decreased by $13.5 million. Sales by type of product included increases in sales of instruments of $2.4 million and service of $8.1 million offset by decreases in consumables of $5.7 million.

Operating profit for the second quarter of 2006 was $25.3 million, versus $15.7 million for the second quarter of 2005, an increase of $9.6 million, or 62%. The increase in operating profit in the second quarter of 2006 as compared to the second quarter of 2005 was primarily the result of a decrease in restructuring charges from $11.0 million in the second quarter of 2005 to $1.1 million in the second quarter of 2006. The second quarter of 2006 includes stock option expense of $0.7 million. Amortization of intangible assets was $7.1 million for the second quarter of 2006 and $6.5 million for the second quarter of 2005.

Operating profit for the six-month period ended July 2, 2006 was $49.1 million, versus $37.6 million for the six-month period ended July 3, 2005, an increase of $11.5 million, or 30%. The increase in operating profit in the six-month period ended July 2, 2006 as compared to the six-month period ended July 3, 2005 was primarily the result of a decrease in restructuring charges from $11.0 million in 2005 to $1.1 million in 2006. The six-month period ended July 2, 2006 includes stock option expense of $1.4 million. Amortization of intangible assets was $13.9 million for the six-month period ended July 2, 2006 and $13.1 million for the six-month period ended July 3, 2005.

Sales for the second quarter of 2006 were $98.5 million, versus $97.2 million for the first quarter of 2005, an increase of $1.3 million, or 1%. Changes in foreign exchange rates had an immaterial impact on sales in the second quarter of 2006, as compared to the second quarter of 2005. The analysis in the remainder of this paragraph compares selected sales by product type for the second quarter of 2006, as compared to the second quarter of 2005, and includes the effect of foreign exchange fluctuations and acquisitions. Sales of our digital imaging products increased by $3.5 million, while sales within our sensors and specialty lighting product lines decreased $2.2 million.

Sales for the six-month period ended July 2, 2006 were $192.1 million, versus $190.6 million for the six-month period ended July 3, 2005, an increase of $1.4 million, or 1%. The effect of acquisitions increased our sales for the six-month period ended July 2, 2006 by $0.6 million, as compared to the six-month period ended July 3, 2005. Changes in foreign exchange rates decreased sales by approximately $1.6 million in the six-month

period ended July 2, 2006, as compared to the six-month period ended July 3, 2005. The analysis in the remainder of this paragraph compares selected sales by product type for the six-month period ended July 2, 2006, as compared to the six-month period ended July 3, 2005, and includes the effect of foreign exchange fluctuations and acquisitions. Sales of our digital imaging products increased by $5.2 million, while sales within our sensors and specialty lighting product lines decreased $3.8 million.

Operating profit for the second quarter of 2006 was $17.4 million, versus $12.9 million for the second quarter of 2005, an increase of $4.5 million, or 35%. The increase in operating profit in the second quarter of 2006, as compared to the second quarter of 2005, was primarily the result of a $1.4 million restructuring credit in the second quarter of 2006 as compared to a $3.2 million restructuring charge in the second quarter of 2005. The operating profit for the second quarter of 2006 includes stock option expense of $0.4 million. Amortization of intangible assets was $0.6 million for the second quarter of 2006 and $0.4 million for the second quarter of 2005. The second quarter of 2005 also included a $0.2 million charge for in-process research and development related to the acquisition of Elcos AG, a leading European designer and manufacturer of custom light emitting diodes, or LED, solutions for biomedical and industrial applications.

Operating profit for the six-month period ended July 2, 2006 was $30.1 million, versus $26.4 million for the six-month period ended July 3, 2005, an increase of $3.7 million, or 14%. The increase in operating profit in the six-month period ended July 2, 2006, as compared to the six-month period ended July 3, 2005, was primarily the result of a $1.4 million restructuring credit in the second quarter of 2006 as compared to the $3.2 million restructuring charge in the second quarter of 2005 offset by a decrease in operating profit due to capacity issues and a shift in customer mix within the amorphous silicon business. The six-month period ended July 2, 2006 includes stock option expense of $0.7 million. Amortization of intangible assets was $1.3 million and $1.2 million for the six-month periods ended July 2, 2006 and July 3, 2005, respectively. The six-month period ended July 3, 2005, also included a $0.2 million charge for in-process research and development related to the Elcos acquisition.

We require cash to pay our operating expenses, make capital expenditures, service our debt and other long-term liabilities and pay dividends on our common stock. Our principal sources of funds are from our operations and the capital markets, particularly the debt markets. In the near term, we anticipate that our operations will generate sufficient cash to fund our operating expenses, capital expenditures, interest payments on our debt and dividends on our common stock. In the long-term, we expect to use internally generated funds and external sources to satisfy our debt and other long-term liabilities.

Principal factors that could affect the availability of our internally generated funds include:

Principal factors that could affect our ability to obtain cash from external sources include:

In October 2005 our Board of Directors reaffirmed our authority to repurchase up to 10.0 million shares of our common stock from time to time on the open market or in privately negotiated transactions until October 21, 2008, unless this authorization is terminated earlier by our Board of Directors. The timing and amount of any shares repurchased will be determined based on our evaluation of market conditions and other factors. The repurchase program may be suspended or discontinued at any time. Any repurchased shares will be available for use in connection with our stock plans and for other corporate programs. We may repurchase up to approximately 1.7 million shares of our common stock under this program in the future. If we continue to repurchase shares, the repurchase program will be funded using our existing financial resources, including cash and cash equivalents. At July 2, 2006, we had cash and cash equivalents of approximately $323.8 million.

Operating Activities. Net cash generated by continuing operations operating activities was $16.4 million for the six months ended July 2, 2006, compared to net cash generated by continuing operations operating activities of $90.9 million for the six months ended July 3, 2005. Principal contributors to the generation of cash from operating activities during the six months ended July 2, 2006 were net income from continuing operations of $48.3 million and depreciation and amortization of $33.4 million. These amounts were offset in part by taxes paid on divestitures of $59.2 million in the first six months of 2006. The net contribution from working capital was flat for the six months ended July 2, 2006, with an increase in inventory of $6.5 million and a decrease in accounts payable of $21.3 million, offset in part by a decrease in accounts receivable of $27.8 million. Strong performance in accounts receivable collections in the Life and Analytical Sciences segment was partially offset by increased accounts payable disbursements in both the Life and Analytical Sciences and Optoelectronics segments. There was no incremental use of our accounts receivable securitization facility during the first six months of 2006, which totaled $45.0 million at both July 2, 2006 and January 1, 2006. Net cash used for changes in accrued expenses, restructuring, other assets and liabilities and other items totaled $6.2 million during the first six months of 2006, and primarily relates to timing of salary and benefit related payments.

Investing Activities. Net cash used in continuing operations investing activities was $30.8 million in the six months ended July 2, 2006, compared to $9.9 million of cash used in the six months ended July 3, 2005. Included in the first six months of 2006 was $25.0 million of net proceeds received from the sale of our semiconductor business and $0.9 million of net proceeds for the sale of an investment. This was offset by approximately $8.7 million, $12.0 million and $12.3 million of net cash used for the purchase of Agilix, Spectral and C&A, respectively. In addition, $11.7 million of business development transaction costs, earn-out payments and other costs were incurred in connection with these and previous transactions. Capital expenditures in the six months ended July 2, 2006 were $21.4 million, mainly in the areas of tooling and other capital equipment purchases and facility improvements. These cash outflows were partially offset by $7.1 million received from the sale of property, plant and equipment and $2.3 million from the settlement of life insurance policies.

Financing Activities. Net cash used in continuing operations financing activities was $171.5 million in the six months ended July 2, 2006, compared to $119.2 million in the six months ended July 3, 2005, an increase of $52.3 million, or 44%. In the six months ended July 2, 2006, we repurchased in the open market 5.0 million shares of our common stock at a total cost of $116.4 million. Debt reductions during the first six months of 2006 totaled $56.6 million, compared to reductions in the first six months of 2005 of $34.1 million. These uses of cash were offset by proceeds from common stock option exercises of $17.1 million and the related tax benefit of $3.6 million. In addition, we paid $18.0 million in dividends in the first six months of 2006.

Senior Unsecured Credit Facility. On October 31, 2005, we entered into a $350.0 million five-year senior unsecured revolving credit facility. Letters of credit in the aggregate amount of approximately $15.0 million, originally issued under our previous credit agreement, are treated as issued under this agreement. We use the senior unsecured credit facility for general corporate purposes which may include working capital, refinancing

existing indebtedness, capital expenditures, share repurchases, acquisitions and strategic alliances. The interest rates under the senior unsecured credit facility are based on the Eurocurrency rate at the time of borrowing plus a margin or the base rate from time to time. The Eurocurrency margin as of July 2, 2006 was 60 basis points. The base rate is the higher of (1) the corporate base rate announced from time to time by Bank of America, N.A. and (2) the Federal Funds rate plus 50 basis points. We may allocate all or a portion of our indebtedness under the senior unsecured credit facility to interest based upon the Eurocurrency rate plus a margin or the base rate. As of July 2, 2006, there were approximately $199.0 million of borrowings under the facility.

Our senior unsecured credit facility contains covenants that require us to maintain specific financial ratios, including:

We have established a wholly owned consolidated subsidiary to purchase, on a revolving basis, certain of our accounts receivable balances and simultaneously sell an undivided interest in this pool of receivables to a financial institution. This facility, which is currently scheduled to expire in January 2007, provides for total funding capacity of $65.0 million to expand our sources of liquidity. Amounts funded under this facility were $45.0 million at both July 2, 2006 and January 1, 2006. As of July 2, 2006, we had approximately $20.0 million of capacity available under the facility. The facility had an effective interest rate of LIBOR plus approximately 40 basis points as of July 2, 2006. The facility includes conditions that require us to maintain a senior unsecured credit rating of BB or above, as defined by Standard & Poor’s Rating Services, and Ba2 or above, as defined by Moody’s Investors Service. In January 2006, we entered into an agreement to extend the term of our accounts receivable securitization facility to January 26, 2007.

Our Board of Directors declared regular quarterly cash dividends of seven cents per share in the first two quarters of 2006 and in each quarter of 2005.

Effective January 2, 2006, we adopted SFAS No. 123(R), Share-Based Payment, which requires compensation costs related to stock-based transactions, including employee stock options, to be recognized in the financial statements based on fair value. SFAS No. 123(R) revises SFAS No. 123, as amended, Accounting for Stock-Based Compensation, and supersedes Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees. Prior to the beginning of 2006, we applied the intrinsic value based method prescribed in APB Opinion No. 25, as permitted by SFAS No. 123, in accounting for employee stock-based compensation. We generally did not recognize compensation expense in connection with the grant of stock options because all options granted had an exercise price equal to the fair market value of the underlying common stock on the date of grant.

In transitioning from APB 25 to SFAS No. 123(R), we have applied the modified prospective method. Accordingly, periods prior to adoption have not been restated and are not directly comparable to periods after adoption. Under the modified prospective method, compensation cost recognized in periods after adoption includes (i) compensation cost for all stock-based payments granted prior to, but not yet vested as of January 2,

2006, based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123, less estimated forfeitures, and (ii) compensation cost for all stock-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123(R), less estimated forfeitures.

The total stock-based compensation expense for the cost of stock options, restricted stock, restricted stock units and performance units was $3.5 million and $6.3 million for the three and six months ended July 2, 2006, respectively. The total income tax benefit recognized in the Consolidated Statements of Income for stock-based compensation was $1.2 million and $2.1 million for the three and six months ended July 2, 2006, respectively. At July 2, 2006, total unrecognized stock-based compensation expense, expected to be recognized over a weighted average period of 2.0 fiscal years, amounted to $15.2 million. Total unrecognized stock-based compensation expense will be adjusted for any future changes in estimated forfeitures, if any.

Prior to the adoption of SFAS No. 123(R), we presented all excess tax benefits related to stock compensation as cash flows from operating activities in our statement of cash flows. SFAS No. 123(R) requires the cash flows resulting from these tax benefits to be classified as cash flows from financing activities. In the first six months of fiscal 2006, the tax benefit from the exercise of stock options was $3.6 million, which was classified as cash flows from financing activities.

In July 2006, Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in the financial statements of an entity in accordance with SFAS No. 109, “Accounting for Income Taxes.” The new interpretation is effective for fiscal years beginning after December 15, 2006. We will be required to adopt the interpretation in the first quarter of fiscal year 2007. We are currently evaluating the requirements of FIN 48 and have not yet determined the impact on our consolidated financial statements.

Market Risk. We are exposed to market risks, relating to both currency exchange rates and interest rates. On occasion, in order to manage the volatility relating to these exposures, we may enter into various derivative transactions pursuant to our policies to hedge against known or forecasted market exposures. We briefly describe several of the market risks we face below. The following disclosure supplements the disclosure provided under the heading, “Item 7A. Quantitative and Qualitative Disclosure About Market Risk,” in our annual report on Form 10-K for the fiscal year ended January 1, 2006.

Foreign Exchange Risk. The potential change in foreign currency exchange rates offers a substantial risk to us, as approximately 60% of our business is conducted outside of the U.S., generally in foreign currencies. Our risk management strategy currently uses forward contracts to mitigate certain foreign currency exposures. The intent is to offset gains and losses that occur on the underlying exposures, with gains and losses resulting from the forward contracts that hedge these exposures. Principal hedged currencies include the British Pound, Canadian Dollar (CAD), Euro (EUR), Japanese Yen (JPY), and Singapore Dollar (SGD). The periods of these forward contracts typically span less than three months. We held forward foreign exchange contracts with U.S. equivalent notional amounts totaling $175.0 million at July 2, 2006 and $214.3 million on July 3, 2005. For the six months ended July 2, 2006, we did not engage in any cash flow hedges. Additionally, we are able to partially mitigate the impact that fluctuations in currencies have on our net income as a result of our manufacturing facilities located in countries outside the U.S., material sourcing and other spending which occur in countries outside the U.S. We do not enter into derivatives for trading or other speculative purposes, nor do we use leveraged financial instruments.

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

Foreign Currency Risk—Value-at-Risk Disclosure. We continue to measure foreign currency risk using the Value-at-Risk model described in our annual report on Form 10-K for the fiscal year ended January 1, 2006. These measures continue to approximate our risks.

Interest Rate Risk. Our debt portfolio, after consideration of the tender offer and repayment of the 6.8% Notes, includes primarily variable rate instruments. Fluctuations in interest rates can therefore have a direct impact on both our short-term cash flows (as they relate to interest) and our earnings.

Interest Rate Risk—Sensitivity. Our annual report on Form 10-K for the fiscal year ended January 1, 2006 presents sensitivity measures for our interest rate risk. We refer to our annual report on Form 10-K for the fiscal year ended January 1, 2006 for our sensitivity disclosure.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of our quarter ended July 2, 2006. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on their evaluation of our disclosure controls and procedures as of the end of our quarter ended July 2, 2006, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended July 2, 2006 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

In papers dated October 23, 2002, Enzo Biochem, Inc. and Enzo Life Sciences, Inc. (collectively “Enzo”) filed a complaint in federal court in New York against us, one of our subsidiaries and several other companies, which is described in more detail in Note 14 to our condensed consolidated financial statements in this quarterly report. On July 17, 2006, the court issued a decision regarding the construction of the claims in Enzo’s patents that effectively limited the coverage of certain of those claims and, we believe, excludes certain of our products from the coverage of Enzo’s patents. Discovery is ongoing and the court has not set a date for trial.

On October 17, 2003, Amersham Biosciences Corp. filed a complaint in federal court in New Jersey against one of our subsidiaries, alleging that certain of our subsidiary’s products infringe three of Amersham’s patents related to high-throughput screening (the “NJ case”). On October 29, 2003, we filed a complaint against Amersham in federal court in Massachusetts, alleging that certain of Amersham’s products infringe two of our patents related to high-throughput screening (the “MA case”). On August 18, 2004, Amersham plc filed a complaint in the Patent Court of the English High Court of Justice against two of our United Kingdom-based subsidiaries, alleging that certain of our products infringe one corresponding Amersham United Kingdom patent granted in August 2004 (the “UK case”). These cases are described in more detail in Note 14 to our condensed consolidated financial statements in this quarterly report. After a trial in the UK case in December 2005, the court ruled in February 2006 that Amersham’s patent in question was invalid in the United Kingdom and awarded costs to us. Amersham’s appeal of the ruling in the UK case is scheduled to be heard in early 2007. On May 23, 2006, the court in the NJ case issued a decision regarding the construction of the claims in Amersham’s patents that adopted many of Amersham’s claim construction positions. We have filed a motion asking the court to reconsider that decision. Discovery has not yet been completed in either the NJ or MA case, nor has a trial date been set in either case. Proceedings in the NJ and MA cases have been stayed while the parties pursue voluntary mediation efforts.

We believe we have meritorious defenses to these lawsuits and the other proceedings described in Note 14, and are contesting the actions vigorously. We are currently unable, however, to reasonably estimate the amount of the loss, if any, that may result from the resolution of these matters or to determine whether resolution of any of these matters will have a material adverse impact on our consolidated financial statements.

We are also subject to various other claims, legal proceedings and investigations covering a wide range of matters that arise in the ordinary course of our business activities. Each of these matters is subject to uncertainties, and it is possible that some of these matters may be resolved unfavorably to us. We have established accruals for potential losses that we believe are probable and reasonably estimable. In the opinion of our management, based on its review of the information available at this time, the total cost of resolving these other contingencies at July 2, 2006 should not have a material adverse effect on our consolidated financial statements.

The following important factors affect our business and operations generally or affect multiple segments of our business and operations:

If we do not introduce new products in a timely manner, we may lose market share and be unable to achieve revenue growth targets.

We sell many of our products in industries characterized by rapid technological change, frequent new product and service introductions, and evolving customer needs and industry standards. Many of the businesses competing with us in these industries have significant financial and other resources to invest in new technologies, substantial intellectual property portfolios, substantial experience in new product development, regulatory expertise, manufacturing capabilities and the distribution channels to deliver products to customers. Our products

could become technologically obsolete over time, or we may invest in technology that does not lead to revenue growth or continue to sell products for which the demand from our customers is declining, in which case we may lose market share or not achieve our revenue growth targets. The success of our new product offerings will depend upon several factors, including our ability to:

Many of our products are used by our customers to develop, test and manufacture their products. Therefore, we must anticipate industry trends and develop products in advance of the commercialization of our customers’ products. In developing new products, we may be required to make significant investments before we can determine the commercial viability of the new product. If we fail to accurately foresee our customers’ needs and future activities, we may invest heavily in research and development of products that do not lead to significant sales.

In addition, some of our licensed technology is subject to contractual restrictions, which may limit our ability to develop or commercialize products for some applications. For example, some of our license agreements are limited to the field of life sciences research, and exclude clinical diagnostics applications.

We may not be able to successfully execute acquisitions or license technologies, integrate acquired businesses or licensed technologies into our existing business, or make acquired businesses or licensed technologies profitable.

We have in the past, and may in the future, supplement our internal growth by acquiring businesses and licensing technologies that complement or augment our existing product lines, such as our acquisitions of Agilix Corporation in February 2006, Spectral Genomics, Inc. in April 2006, Clinical & Analytical Service Solutions Ltd. in June 2006 and J.N. Macri Technologies LLC and NTD Laboratories, Inc. in July 2006. However, we may be unable to identify or complete promising acquisitions or license transactions for many reasons, including:

Some of the businesses we may seek to acquire may be unprofitable or marginally profitable. Accordingly, the earnings or losses of acquired businesses may dilute our earnings. For these acquired businesses to achieve acceptable levels of profitability, we must improve their management, operations, products and market penetration. We may not be successful in this regard and may encounter other difficulties in integrating acquired businesses into our existing operations, such as incompatible management, information or other systems or cultural differences.

To finance our acquisitions, we may have to raise additional funds, either through public or private financings. We may be unable to obtain such funds or may be able to do so only on terms unacceptable to us.

We may not be successful in adequately protecting our intellectual property.

Patent and trade secret protection is important to us because developing new products, processes and technologies gives us a competitive advantage, although it is time-consuming and expensive. We own many United States and foreign patents and intend to apply for additional patents. Patent applications we file, however,

may not result in issued patents or, if they do, the claims allowed in the patents that issue may be narrower than what is needed to protect fully our products, processes and technologies. Similarly, applications to register our trademarks may not be granted in all countries in which they are filed. For our intellectual property that is protected by keeping it secret, such as trade secrets and know-how, we may not use adequate measures to protect this intellectual property.

Third parties may also challenge the validity of our issued patents, may circumvent or “design around” our patents and patent applications, or may claim that our products, processes or technologies infringe their patents. In addition, third parties may assert that our product names infringe their trademarks. We may incur significant expense in legal proceedings to protect our intellectual property against infringement by third parties or to defend against claims of infringement by third parties. Claims by third parties in pending or future lawsuits could result in awards of substantial damages against us or court orders that could effectively prevent us from manufacturing, using, importing or selling our products in the United States or other countries.

If we are unable to renew our licenses or otherwise lose our licensed rights, we may have to stop selling products or we may lose competitive advantage.

We may not be able to renew our existing licenses, or licenses we may obtain in the future, on terms acceptable to us, or at all. If we lose the rights to a patented or other proprietary technology, we may need to stop selling products incorporating that technology and possibly other products, redesign our products or lose a competitive advantage. Potential competitors could in-license technologies that we fail to license and potentially erode our market share.

Our licenses typically subject us to various economic and commercialization obligations. If we fail to comply with these obligations we could lose important rights under a license, such as the right to exclusivity in a market. In some cases, we could lose all rights under the license. In addition, rights granted under the license could be lost for reasons out of our control. For example, the licensor could lose patent protection for a number of reasons, including invalidity of the licensed patent, or a third party could obtain a patent that curtails our freedom to operate under one or more licenses.

We encounter aggressive competition from numerous competitors in many areas of our business. We may not be able to compete effectively with all of these competitors. To remain competitive, we must develop new products and periodically enhance our existing products. We anticipate that we may also have to adjust the prices of many of our products to stay competitive. In addition, new competitors, technologies or market trends may emerge to threaten or reduce the value of entire product lines.

Our quarterly operating results could be subject to significant fluctuation, and we may not be able to adjust our operations to effectively address changes we do not anticipate.

Given the nature of the markets in which we participate, we cannot reliably predict future sales and profitability. Changes in competitive, market and economic conditions may require us to adjust our operations, and we may not be able to make those adjustments or to make them quickly enough to adapt to changing conditions. A high proportion of our costs are fixed, due in part to our research and development and manufacturing costs. Thus, small declines in sales could disproportionately affect our operating results in a quarter. Factors that may affect our quarterly operating results include:

If we are unable to produce an adequate quantity of products, such as our digital x-ray detectors, to meet our customers’ demands, our revenue growth may be adversely affected.

We have an established global manufacturing base with facilities in multiple locations around the world. Each of these facilities faces risks to its production capacity that may relate to natural disasters, labor relations or regulatory compliance. In addition, in any of these facilities, such as our Optoelectronics amorphous silicon facility in Santa Clara, California, we may not manage the manufacturing or production processes at expected levels, we may fail to anticipate or act on the need to increase the production capacity, or we may be unable to quickly resolve technical manufacturing issues that arise from time to time. Any of these risks could cause our revenue growth to be adversely affected.

If we fail to maintain satisfactory compliance with the regulations of the United States Food and Drug Administration and other governmental agencies, we may be forced to recall products and cease their manufacture and distribution, and we could be subject to civil or criminal penalties.

Some of the products produced by our Life and Analytical Sciences segment are subject to regulation by the United States Food and Drug Administration (“FDA”) and similar international agencies. These regulations govern a wide variety of product activities, from design and development to labeling, manufacturing, promotion, sales, resales and distribution. If we fail to comply with those regulations or those of similar international agencies, we may have to recall products, cease their manufacture and distribution, and may be subject to fines or criminal prosecution.

Changes in governmental regulations may reduce demand for our products or increase our expenses.

We compete in markets in which we or our customers must comply with federal, state, local and foreign regulations, such as environmental, health and safety, and food and drug regulations. We develop, configure and market our products to meet customer needs created by these regulations. Any significant change in these regulations could reduce demand for our products or increase our costs of producing these products.

Economic, political and other risks associated with foreign operations could adversely affect our international sales.

Because we sell our products worldwide, our businesses are subject to risks associated with doing business internationally. Our sales originating outside the United States represented the majority of our total sales in the quarter ended July 2, 2006. We anticipate that sales from international operations will continue to represent a substantial portion of our total sales. In addition, many of our manufacturing facilities, employees and suppliers are located outside the United States. Accordingly, our future results of operations could be harmed by a variety of factors, including:

If we do not retain our key personnel, our ability to execute our business strategy will be limited.

Our success depends to a significant extent upon the continued service of our executive officers and key management and technical personnel, particularly our experienced engineers, and on our ability to continue to attract, retain, and motivate qualified personnel. The competition for these employees is intense. The loss of the services of one or more of our key personnel could have a material adverse effect on our operating results. In addition, there could be a material adverse effect on us should the turnover rates for engineers and other key personnel increase significantly or if we are unable to continue to attract qualified personnel. We do not maintain any key person life insurance policy on any of our officers or employees.

Restrictions in our senior unsecured credit facility may limit our activities.

Our senior unsecured credit facility contains, and future debt instruments to which we may become subject may contain, restrictive covenants that limit our ability to engage in activities that could otherwise benefit our company. Our new senior unsecured credit facility includes restrictions on our ability and the ability of our subsidiaries to:

We are also required to meet specified financial ratios under the terms of our senior unsecured credit facility. Our ability to comply with these financial restrictions and covenants is dependent on our future performance, which is subject to prevailing economic conditions and other factors, including factors that are beyond our control such as foreign exchange rates, interest rates, changes in technology and changes in the level of competition.

Our failure to comply with any of these restrictions in our senior unsecured credit facility may result in an event of default under that facility, which could permit acceleration of the debt under that facility, and require us to prepay that debt before its scheduled due date.

Our results of operations will be adversely affected if we fail to realize the full value of our intangible assets.

As of July 2, 2006, our total assets included $1.4 billion of net intangible assets. Net intangible assets consist principally of goodwill associated with acquisitions and costs associated with securing patent rights, trademark rights and technology licenses, net of accumulated amortization. We test certain of these items—specifically all of those that are considered “non-amortizing”—on an annual basis for potential impairment by comparing the carrying value to the fair market value of the reporting unit to which they are assigned. All of our amortizing intangible assets are evaluated for impairment should discrete events occur that call into question the recoverability of the intangible.

Adverse changes in our business or the failure to grow our Life and Analytical Sciences business may result in impairment of our intangible assets which could adversely affect our results of operations.

On October 21, 2005 our Board of Directors reaffirmed our authority to repurchase up to 10,000,000 shares of our common stock, which we publicly disclosed on November 14, 2005 (the “Program”). This Program will expire on October 21, 2008, unless it is earlier terminated by our Board of Directors. During the fourth quarter of 2005, we repurchased 1,096,000 shares of our common stock in the open market under the Program at an aggregate cost of $24.4 million, including commissions. During the first quarter of 2006, we purchased 5,000,000 shares of our common stock in the open market under the Program at an aggregate cost of $116.4 million, including commissions. We did not purchase any shares of our common stock in the second quarter of 2006. Subsequent to the quarter ended July 2, 2006, we repurchased approximately 2.2 million shares of our common stock in the open market under the Program at an aggregate cost of approximately $41.3 million, including commissions, leaving us with remaining authorization under the Program to repurchase up to approximately 1.7 million shares in the future.

Information regarding matters submitted to a vote of security holders during the quarter ended July 2, 2006 is set forth under the heading “Item 4. Submission of Matters to a Vote of Security Holders” in our quarterly report on Form 10-Q for the quarter ended April 2, 2006.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
