STERIS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

For the Three and Six Months Ended

September 30, 2004 and 2003

(dollars in thousands, except per share amounts)

1. Basis of Presentation

Throughout this document, references to “STERIS Corporation,” “STERIS,” or the “Company,” are references to STERIS Corporation and its subsidiaries.

The Company’s fiscal year ends on March 31. Reference to a particular “year” or “year-end” refers to the Company’s fiscal year.

Nature of Operations

The Company develops, manufactures, and markets infection prevention, contamination control, microbial reduction, and surgical and critical care support products and services for healthcare, scientific, research, industrial, and governmental customers throughout the world. The Company operates in three business segments: Healthcare, Life Sciences, and STERIS Isomedix Services.

Interim Financial Statements

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements contain all material adjustments (consisting of normal recurring accruals and adjustments) necessary to present fairly the financial condition, results of operations, and cash flows of the Company for the periods presented.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk,” and the consolidated financial statements and notes thereto included in Items 7, 7A, and 8, respectively, of the Company’s Annual Report on Form 10-K for the year ended March 31, 2004, filed with the Securities and Exchange Commission on June 14, 2004. The consolidated balance sheet at March 31, 2004 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated upon consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions in certain circumstances that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates and, therefore, operating results for the three and six month periods ended September 30, 2004 are not necessarily indicative of results that may be expected for the fiscal year ending March 31, 2005.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period’s presentation.

Significant Accounting Policies

A detailed description of the Company’s significant and critical accounting policies, estimates, and assumptions is included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2004 filed with the Securities and Exchange Commission on June 14, 2004 in the section of Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” titled, “Critical Accounting Policies, Estimates, and Assumptions,” and in Note 1 to the consolidated financial statements, “Accounting Policies.” The Company’s significant and critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2004.

Stock-based Compensation

The Company has granted nonqualified stock options to certain employees to purchase the Company’s Common Shares at the market price on the date of grant. Stock options granted generally become exercisable to the extent of one-fourth of the optioned shares for each full year of employment following the date of grant and expire approximately 10 years after the date of grant, or earlier if an option holder ceases to be employed by the Company. Certain option agreements have provisions that provide for an adjustment to the normal vesting schedule, whereby, options vest on a prorated basis as defined by specific option agreements in the event of employment termination. The Company accounts for stock-based compensation under the provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” as permitted by Statement of Financial Accounting Standards No. 123 (SFAS No. 123), “Accounting for Stock-Based Compensation,” as amended by Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation - Transition and Disclosure,” and accordingly recognizes no compensation expense when the exercise price equals the market price of the stock on the date of grant.

The following table illustrates the effect on the Company’s net income, earnings per basic Common Share, and earnings per diluted Common Share, had compensation cost for all options been determined based upon the fair market value recognition provisions of SFAS No. 123:

	Three Months Ended September 30,				Six Months Ended September 30,
	2004		2003		2004		2003

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

For the Three and Six Months Ended

September 30, 2004 and 2003

(dollars in thousands, except per share amounts)

For the purpose of computing pro forma net income, the fair value of option grants was estimated at their grant date using the Black-Scholes option pricing model and the following assumptions for the three and six months ended September 30, 2004 and 2003:

	Three Months Ended September 30,				Six Months Ended September 30,
	2004		2003		2004		2003
Risk free interest rate	3.54%-5.50	%	3.54%-6.46	%	3.54%-5.50	%	3.54%-6.46	%
Dividend yield	0	%	0	%	0	%	0	%
Expected volatility	45	%	45	%	45	%	45	%
Option life (in years)	5		5		5		5

The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable, characteristics that are not present in the Company’s option grants. If the model permitted consideration of the unique characteristics of employee stock options, the resulting estimate of the fair value of the stock options could be different.

Recently Issued Accounting Standards and Accounting Standards Pending Adoption

In December 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Act”) was signed into law. The Act expands Medicare benefits, primarily adding a prescription drug benefit for Medicare-eligible retirees beginning in 2006. The law provides a federal subsidy to companies that sponsor post-retirement healthcare plans that provide prescription drug coverage. In May 2004, the Financial Accounting Standards Board issued FASB Staff Position No. 106-2 (“FSP No. 106-2”), “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003,” that provides guidance on the accounting for the effects of the Act for employers that sponsor post-retirement healthcare plans with prescription drug benefits. FSP No. 106-2 also requires those employers to provide certain disclosures regarding the effect of the federal subsidy provided by the Act. FSP No. 106-2 is generally effective for the first interim or annual reporting period beginning after June 15, 2004. The Company has adopted FSP No. 106-2 as of July 1, 2004. The Company has elected under the provisions of FSP No. 106-2, to defer recognizing any potential subsidy from the Act, until the final regulations necessary to fully implement the Act are issued. The reported post-retirement benefit cost for the three and six months ended September 30, 2004, presented in Note 7, “Benefit Plans,” does not reflect the effects of the Act on the Company’s post-retirement benefit plan.

In December 2003, the FASB revised Statement of Financial Accounting Standards No. 132 (“SFAS No. 132”), “Employers’ Disclosures about Pension and Other Post-retirement Benefits.” As revised, SFAS No. 132 requires additional disclosures for defined benefit pension and other post-retirement benefit plans including quarterly disclosure of the various components of net periodic benefit costs and expanded annual disclosures about plan assets, obligations, cash flows, net periodic benefit cost, and investment strategies. Note 7, “Benefit Plans,” includes the additional pension and other post-retirement benefit plan disclosures required by SFAS No. 132.

2. Business Acquisition

On September 15, 2004, the Company announced that it had acquired Albert Browne Limited and its subsidiaries (“Browne”), a privately-held manufacturer of chemical indicators, headquartered in Leicester, England for 28.9 million British pounds sterling ($52,132), net of 3.2 million British pounds sterling ($5,807) of cash acquired at the close of the transaction. Browne is a leading provider of chemical indicators to healthcare facilities in over 70 countries. The acquisition provides the Company with an established European distribution channel and expands the Company’s offering of consumable products used with its broad line of capital equipment for infection control and decontamination.

The purchase price is subject to the final settlement of certain working capital adjustments as guaranteed by the seller. The purchase price of $58,730, which includes costs associated with the transaction, has been preliminarily allocated to net assets and goodwill and is subject to further adjustment as the Company finalizes costs associated with the acquisition and the valuation of identified intangible assets and certain tangible assets acquired and liabilities assumed.

STERIS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

For the Three and Six Months Ended

(dollars in thousands, except per share amounts)

The consolidated financial statements include the operating results of Browne from the date of acquisition. Pro forma results of operations have not been presented because the effect of this acquisition is not deemed significant. Goodwill created as a result of this acquisition has been allocated to the Company’s Healthcare segment.

3. Common Shares

Basic earnings per share is calculated based upon the weighted average number of Common Shares outstanding. Diluted earnings per share is calculated based upon the weighted average number of Common Shares outstanding plus the dilutive effect of Common Share equivalents determined using the treasury stock method. The following is a summary of Common Shares and Common Share equivalents outstanding used in the calculations of basic and diluted earnings per share:

		Three Months Ended September 30,					Six Months Ended September 30,
		2004		2003			2004		2003
				(shares in thousands)
	Weighted average Common Shares outstanding - basic		69,010		69,347			69,243		69,403
	Dilutive effect of Common Share equivalents		734		1,223			850		1,264
	Weighted average Common Shares and equivalents - diluted		69,744		70,570			70,093		70,667
Options to purchase the following number of Common Shares at the following weighted average exercise prices were outstanding but excluded from the computation of diluted earnings per share because the exercise prices were greater than the average market price for the Common Shares during the period:
		Three Months Ended September 30,					Six Months Ended September 30,
		2004		2003			2004		2003
				(shares in thousands)
	Number of Common Share options		2,566		617			1,568		617
	Weighted average exercise price	$	25.06	$	30.45		$	28.27	$	30.45
4. Comprehensive Income Statement of Financial Accounting Standards No. 130, “Reporting Comprehensive Income,” establishes standards for reporting comprehensive income. Comprehensive income includes net income as currently reported under U.S. generally accepted accounting principles and other comprehensive income. Other comprehensive income considers the effect of additional economic events that are not required to be recorded in determining net income, but rather are reported as a separate component of shareholders’ equity. The following table illustrates the components of the Company’s comprehensive income for the three and six month periods ended September 30, 2004 and 2003:
		Three Months Ended September 30,					Six Months Ended September 30,
		2004		2003			2004		2003
	Net income	$	18,893	$	20,369		$	36,510	$	36,841
	Foreign currency translation adjustments		7,194		(142	)		5,734		5,311
	Total comprehensive income	$	26,087	$	20,227		$	42,244	$	42,152

5. Inventories

Inventories are stated at the lower of cost or market. The Company uses the last-in, first-out (LIFO) and first-in, first-out (FIFO) cost methods. An actual valuation of inventory under the LIFO method is made only at the end of the fiscal year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and are subject to the final year-end LIFO inventory valuation. Inventory costs include material, labor, and overhead. Inventories consisted of the following:

	September 30, 2004	March 31, 2004
Raw materials	$  26,556	$  27,916
Work in process	18,946	24,420
Finished goods	58,212	45,913
Total inventories	$103,714	$  98,249

6. Income Taxes

Income tax expense includes U.S. federal, state and local, and foreign income taxes, and is based on reported pre-tax income. Income tax expense is provided on an interim basis based upon the Company’s estimate of the annual effective income tax rate. In determining the estimated annual effective income tax rate, the Company analyzes various factors, including projections of the Company’s annual earnings and taxing jurisdictions that the earnings will be generated in, the impact of state and local income taxes, the Company’s ability to utilize tax credits and net operating loss carryforwards, and available tax planning alternatives. The effective income tax rates for the three month periods ended September 30, 2004 and 2003 were 37.4% and 36.0%, respectively. For the six month periods ended September 30, 2004 and 2003, the effective income tax rates were 36.5% and 36.0%, respectively.

7. Benefit Plans

The Company provides defined benefit pension plans for certain manufacturing and plant administrative personnel throughout the world as determined by collective bargaining agreements or employee benefit standards set at the time of acquisition of certain businesses. In addition to providing pension benefits to certain employees, the Company sponsors an unfunded post-retirement medical benefit plan for a group of U.S. employees comprised substantially of the same employees who receive pension benefits under the U.S. defined benefit plans. Benefits under this plan include retiree life insurance and retiree medical insurance, including prescription drug coverage and Medicare supplemental coverage. Additional information regarding the Company’s defined benefit pension plans and post-retirement medical benefit plan, including detailed information regarding employees covered and assumptions used to determine the benefit obligation and net periodic benefit cost is included in Note 9, “Benefit Plans,” to the Company’s consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on June 14, 2004.

8. Contingencies

The Company is involved in various patent, product liability, consumer, commercial, environmental, tax proceedings and claims, government investigations, and other legal proceedings that arise from time to time in the ordinary course of business. In accordance with Statement of Financial Accounting Standards No. 5, “Accounting for Contingencies,” the Company records accruals for such contingencies to the extent that the Company concludes that their occurrence is both probable and estimable. The Company considers many factors in making these assessments, including the professional judgment of experienced members of management and the Company’s legal counsel. The Company has made estimates as to the likelihood of unfavorable outcomes and the amounts of such potential losses. In the opinion of management, the ultimate outcome of these proceedings and claims is not anticipated to have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. Litigation is inherently unpredictable and actual results could differ from the Company’s estimates. The Company records anticipated recoveries under applicable insurance contracts when assured of recovery.

To the extent that management of the Company believes it is probable that a taxing authority will take a sustainable position on a matter contrary to the position taken by the Company, the Company provides tax accruals. If the Company prevails in matters for which accruals have been established or is required to pay amounts in excess of established accruals, the Company’s effective income tax rate in a given financial statement period may be materially impacted.

Refer to Part II, Item I, “Legal Proceedings,” on page 29 of this Form 10-Q.

11. Financial and Other Guarantees

The Company generally offers a limited one-year parts and labor warranty on its capital equipment. The specific terms and conditions of those warranties vary depending on the product sold and the country where the Company conducts business. The Company provides for the estimated cost of product warranties at the time product revenue is recognized. Amounts due to customers for the Company’s future performance under these warranties are recorded as a current liability on the accompanying consolidated balance sheets. Factors that affect the Company’s warranty liability include the number and type of installed units, historical and anticipated rates of product failures, and material and service costs per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Changes to the Company’s warranty liability during the first half of fiscal 2005 were as follows:

Balance, March 31, 2004	$	5,914
Warranties issued during the period		3,325
Settlements made during the period		(3,850	)
Balance, September 30, 2004	$	5,389

The Company also issues product maintenance contracts to its customers that are accounted for in accordance with the requirements of FASB Technical Bulletin No. 90-1, “Accounting for Separately Priced Extended Warranty and Product Maintenance Contracts.” Such contracts generally range in terms from 1 to 5 years and require the Company to maintain and repair the Company’s product over the maintenance contract term. Amounts received from customers under these contracts are initially recorded as a liability for deferred service contract revenue on the accompanying consolidated balance sheets. The liability recorded for deferred service contract revenue was $13,363 and $12,342 as of September 30, 2004 and March 31, 2004, respectively. Such deferred service contract revenue is then amortized on a straight-line basis over the contract term and recognized as service revenue on the accompanying consolidated statements of income. The activity related to the liability for deferred service contract revenue has been excluded from the table presented above.

12. Foreign Currency Forward Contracts

The Company has entered into foreign currency forward contracts with notional values of 8.0 million euro and 3.0 million British pounds sterling to reduce its transactional foreign currency exposures. The estimated fair value of these forward contracts was $8 at September 30, 2004 and is included in “Accrued expenses and other” on the accompanying consolidated balance sheets. The contracts are marked to market, with gains and losses recognized in the consolidated statements of income.

STERIS Corporation

We have reviewed the consolidated balance sheet of STERIS Corporation and subsidiaries as of September 30, 2004, and the related consolidated statements of income for the three and six month periods ended September 30, 2004 and 2003, and the consolidated statements of cash flows for the six month periods ended September 30, 2004 and 2003. These financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of STERIS Corporation and subsidiaries as of March 31, 2004 and the related consolidated statements of income, shareholders’ equity and cash flows for the year then ended, not presented herein, and in our report dated June 4, 2004, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of March 31, 2004, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

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

Non-GAAP Financial Measures

In the following sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations, the Company, at times, may refer to information extracted from the Company’s consolidated financial statements, but not required to be presented in the financial statements under U.S. generally accepted accounting principles. Certain of this information is considered to be “non-GAAP financial measures” under the Securities and Exchange Commission rules. The Company has used the following non-GAAP financial measures in the context of this report on Form 10-Q: Backlog, debt to capital, and days sales outstanding. The Company defines these non-GAAP financial measures as follows:

• Backlog- is defined by the Company as the amount of unfilled purchase orders at a point in time. At September 30, 2004, June 30, 2004, and September 30, 2003, the Company’s backlog amounted to $133.5 million, $133.4 million, and $152.6 million, respectively. Backlog at September 30, 2004 was comprised of $72.4 million related to the Company’s Healthcare segment and $61.1 million related to the Company’s Life Sciences segment. Management uses this figure as a measure to assist in the projection of short-term financial results and inventory requirements.

• Debt to capital- is defined by the Company as total long-term debt divided by the sum of long-term debt and shareholders’ equity. At September 30, 2004 and March 31, 2004, the Company’s debt to capital amounted to 13.2% and 13.8%, respectively. Management uses this figure as a financial liquidity measure to gauge the Company’s ability to borrow, provide strength/protection against creditors, fund growth, develop outside of current business operations, and measure the risk of the Company’s financial structure.

• Days sales outstanding- is defined by the Company as the average collection period for sales revenue. It is calculated as net accounts receivable divided by the trailing four quarters revenues, multiplied by 365. At September 30, 2004 and March 31, 2004, the Company’s days sales outstanding amounted to 80 days and 86 days, respectively. Management uses this figure to help gauge the quality of accounts receivable.

The Company has presented these measures because it believes that meaningful analysis of the Company’s financial performance is enhanced by an understanding of certain additional factors underlying that performance and management’s judgments about those particular factors.

Executive Overview

The Company recognized net income of $18.9 million, or $0.27 per diluted share, during the second quarter of fiscal 2005, representing a decrease of 7.2% from the comparable prior year period’s net income of $20.4 million, or $0.29 per diluted share. For the first six months of fiscal 2005, net income was flat as compared to the same prior year period. Net income for both periods was negatively impacted by weakness in the Company’s Life Sciences segment, which experienced ongoing volume declines.

Revenues for the second quarter of fiscal 2005 were $264.8 million, an increase of $7.5 million, or 2.9%, as compared to $257.4 million during the prior year second quarter. For the first six months of fiscal 2005, revenues were $519.6 million as compared to $516.7 million for the same period of fiscal 2004, representing an increase of $3.0 million, or 0.6%. Increased revenues in the Company’s Healthcare segment, where capital equipment demand continued to improve, and mid-teen percentage revenue growth in the Company’s Isomedix Services segment, were the main drivers of improved overall revenues. These factors were partially offset by a decline in revenues in the Company’s Life Sciences segment, which was impacted by a number of consolidations within the European pharmaceutical industry that led to the cancellation or delay of several new facility construction projects. The Life Sciences segment also experienced softness in demand from North American customers reflecting cautiousness regarding capital spending.

15

The Company’s gross profit percentage was 42.1% for the second quarter of fiscal 2005 as compared to 43.0% for the second quarter of fiscal 2004. The 90 basis point decline in the gross profit percentage quarter over quarter was a result of lower margins in the Life Sciences segment driven by lower volumes and a slight decline in the Healthcare segment reflecting a change in revenue mix. The quarter’s gross profit percentage was also negatively impacted by changes in foreign currency exchange rates in relation to the U.S. dollar. The Company’s gross profit percentage was 42.6% for the first half of fiscal 2005 as compared to 42.0% for the first half of fiscal 2004. The fiscal 2005 year to date gross profit percentage exceeded the prior year levels as a result of the generation of a higher margin revenue mix during the first quarter of fiscal 2005 as compared to the first quarter of fiscal 2004.

The Company continues to focus its capital spending on investments in new and existing facilities, business expansion projects, and information technology improvements. In the first half of fiscal 2005, capital expenditures amounted to $25.5 million, of which $15.0 million related to second quarter spending. The Company also continued to step up its investment in research and development to strengthen its competitive position in global marketplaces. The increase in research and development expenditures during the first six months of fiscal 2005 reflects an increased emphasis on new product development, product improvements, development of new technological innovations, and the focus of research and development efforts on the streamlining of manufacturing processes and the standardization of products.

During the second quarter of fiscal 2005, the Company announced that it had acquired Albert Browne Limited, a manufacturer of chemical indicators based in the United Kingdom. This acquisition provides the Company with an established European distribution channel that fits the Company’s strategic goal of expanding its offering of consumable products used with its broad line of capital equipment for infection control and decontamination.

Results of Operations

In the following subsections, the Company has presented its fiscal 2005 second quarter and fiscal 2005 year to date results of operations, and has compared these results to the corresponding periods of the prior fiscal year.

Revenues

As prescribed by Regulation S-X, the Company has presented separately on its Consolidated Statements of Income for each period presented, revenues generated as either product revenues or service revenues. In discussing revenues, the Company, at times, may refer to revenues in differing detail than that which is prescribed by Regulation S-X. Although the terminology that the Company employs to describe revenues may be similar to the terms used by other companies, the definitions and uses of these terms may differ significantly among companies. The Company uses the following terms to describe revenues:

• Revenues- The Company’s revenues are presented net of sales returns and allowances.

• Product Revenues- Product revenues are defined by the Company as revenues generated from sales of capital equipment, which includes steam and low temperature liquid sterilizers, washing systems, freeze dryers, VHP technology, water stills, and pure steam generators; surgical lights and tables; and the consumable family of products, which includes STERIS SYSTEM 1^® consumables, sterility assurance products, skin care products, and cleaning consumables.

• Service Revenues- Service revenues are defined by the Company as revenues generated from parts and labor associated with the maintenance, repair, and installation of the Company’s capital equipment, as well as revenues generated from contract sterilization offered through the Company’s Isomedix Services segment.

• Capital Revenues- Capital revenues are defined by the Company as revenues generated from sales of capital equipment, which includes steam and low temperature liquid sterilizers, washing systems, freeze dryers, VHP technology, water stills, and pure steam generators; and surgical lights and tables.

• Consumable Revenues- Consumable revenues are defined by the Company as revenues generated from sales of the consumable family of products which includes STERIS SYSTEM 1^® consumables, sterility assurance products, skin care products, and cleaning consumables.

• Recurring Revenues- Recurring revenues are defined by the Company as revenues generated from sales of consumable products and service revenues.

Quarter over Quarter Comparison

Revenues for the second quarter of fiscal 2005 were $264.8 million, an increase of $7.5 million, or 2.9%, as compared to $257.4 million during the prior year second quarter. Improved overall revenues, quarter over quarter, were driven by a 10.4% increase in service revenues, primarily the result of increased demand and higher utilization of recently expanded facilities capacity in the Company’s Isomedix Services segment. Overall revenues were further positively impacted by a 4.0% increase in consumable revenues, primarily the result of increased sales of consumable products within the Company’s Life Sciences segment. Overall revenues for the quarter were negatively impacted by a net decrease of $3.1 million, or 2.5%, in capital revenues as compared to the second quarter of fiscal 2004. The net decrease in capital revenues was attributable to weakness in demand within the Company’s Life Sciences segment, where revenues generated from sales of capital equipment decreased 20.8% from the comparable prior year period. Weak demand for capital equipment within the Life Sciences segment resulted from the cancellation or delay of several new facility construction projects, particularly in Europe where there have been numerous consolidations, and more prevalent cautiousness in the North American market regarding capital spending. An increase in revenues throughout the Company’s Canadian and Asia Pacific markets partially offset the aforementioned revenue declines in Europe and North America. Capital revenues within the Company’s Healthcare segment improved 7.2%, as compared to the second quarter of fiscal 2004, as a result of increased demand generated from recent hospital facility expansions and renovations which have shifted the segment’s revenues from smaller orders, typically associated with the replacement of aging equipment, to large-order, project-related capital equipment. This demand within the Healthcare segment served to partially offset weaknesses in Life Sciences capital revenues.

International revenues for the quarter amounted to $54.5 million, representing an increase of $1.2 million, or 2.3%, as compared to the second quarter of fiscal 2004. International revenues were positively impacted by an increase in recurring revenues of $6.5 million, or 42.7%, as compared to the second quarter of fiscal 2004. International revenues were negatively impacted by a decrease in capital revenues of $5.3 million, or 14.0%, as compared to the second quarter of fiscal 2004, primarily a result of weaknesses in the Life Sciences segment throughout Europe. The decline in European capital equipment sales was partially offset by increased demand in the Company’s Canadian and Asia Pacific markets.

United States revenues for the quarter amounted to $210.3 million, representing an increase of $6.3 million, or 3.1%, as compared to the second quarter of fiscal 2004. United States revenues were positively impacted by an increase in recurring revenues of $4.0 million, or 3.3%, primarily attributable to increased service revenues within the Company’s Isomedix Services segment. United States revenues were also positively impacted during the quarter by a net increase in capital revenues of $2.3 million, or 2.7%, as compared to the second quarter of fiscal 2004, reflecting increased demand generated from recent hospital facility expansions and renovations.

Year over Year Comparison

Revenues for the first half of fiscal 2005 were $519.6 million, an increase of $3.0 million, or 0.6%, as compared to $516.7 million during the first half of fiscal 2004. Improved overall revenues, year over year, were driven by a 10.1% increase in service revenues, primarily as a result of increased demand and higher utilization of recently expanded facilities capacity within the Company’s Isomedix Services segment and growth in the Life Sciences segment. Overall revenues for the year to date period were favorably impacted by a 2.4% increase in sales of consumable products, primarily within the Company’s Life Sciences segment. Capital revenues declined $15.8 million, or 6.4%, as compared to the first half of fiscal 2004. The net decrease in capital revenues, year over year, was attributable to weakness in demand within the Company’s Life Sciences segment, where revenues generated from capital equipment decreased 18.2%. Year over year, capital revenues generated within the Company’s Healthcare segment remained flat, as a result of a surge in large-order, project-related capital equipment sales during the second quarter of fiscal 2005, which served to offset lower levels of capital equipment sales in the first quarter of fiscal 2005.

International revenues for the first half of fiscal 2005 amounted to $105.3 million, a decrease of $8.4 million, or 7.4%, as compared to the first half of fiscal 2004. The decline in year over year international revenues was attributable to lower levels of international capital equipment sales in Europe. The reduced capital equipment sales were prevalent in the Company’s Life Sciences and Healthcare segments, where international capital equipment sales declined 23.0% and 15.5%, respectively. The declines in European capital equipment sales were partially offset by increased demand in the Company’s Canadian and Asia Pacific markets.

United States revenues for the first half of fiscal 2005 amounted to $414.4 million, an increase of $11.4 million, or 2.8%, as compared to the first half of fiscal 2004. United States revenues were positively impacted by an increase in recurring revenues of $11.1 million, or 4.7%, primarily attributable to service revenues within the Company’s Isomedix Services segment. Year over year, capital revenues generated in the United States remained flat as a result of a surge in large-order, project-related capital equipment sales during the second quarter of fiscal 2005, which served to offset lower levels of capital equipment sales during the first quarter of fiscal 2005.

Product		42.7	%		42.0	%
Service		42.5	%		42.2	%
Total Gross Profit Percentage		42.6	%		42.0	%

Gross profit is impacted by the volume, pricing, and mix of sales of the Company’s products and services, as well as the costs associated with the products and services that are sold. The Company’s gross profit percentage was 42.1% for the second quarter of fiscal 2005, as compared to 43.0% for the second quarter of fiscal 2004. The 90 basis point decline in the gross profit percentage, quarter over quarter, was a result of lower margins in the Life Sciences segment driven by lower volumes and a slight decline in the Healthcare segment reflecting a change in revenue mix. The quarter’s gross profit percentage was also negatively impacted by changes in foreign currency exchange rates in relation to the U.S. dollar. The Company’s gross profit percent was 42.6% for the first half of fiscal 2005 as compared to 42.0% for the first half of fiscal 2004. The fiscal 2005 year to date gross profit percentage exceeded the prior year levels as a result of the generation of a higher margin revenue mix during the first quarter of fiscal 2005 as compared to the first quarter of fiscal 2004. Gross profit percentage for the first half of fiscal 2004 was negatively impacted by costs associated with the closing of an Australian manufacturing facility during the first quarter.

Research and Development	17,988	14,078		3,910		27.8	%
Total Operating Expenses	$162,498	$158,637	$	3,861		2.4	%

Significant components of total selling, general, and administrative expenses are compensation and associated costs, fees for professional services, travel and entertainment, and other general and administrative expenses. As a percentage of total revenues, selling, general, and administrative expenses were 27.2% and 27.8% for the three and six month periods ended September 30, 2004, respectively, as compared to 27.9% and 28.0%, respectively, for the comparable prior year periods. Selling, general, and administrative expenses remained relatively flat for the three and six month periods ended September 30, 2004, as compared to the same prior year periods.

As a percentage of total revenues, research and development expenses were 3.3% and 3.5% for the three and six month periods ended September 30, 2004, respectively, as compared to 2.5% and 2.7%, respectively, for the same prior year periods. For the three and six month periods ended September 30, 2004, research and development expenses increased 35.3% and 27.8% to $8.7 million and $18.0 million, respectively, as compared to $6.4 million and $14.1 million during the same prior year periods. The increase in research and development expenses during both periods is attributable to an increased emphasis on new product development, product improvements, development of new technological innovations, and the focus of research and development efforts on the streamlining of manufacturing processes and standardization of products.

Interest Expense, Net

The following table illustrates the changes in interest expense, net for the three and six month periods ended September 30, 2004 and 2003:

(dollars in thousands)	Three Months Ended September 30,				Change
	2004		2003
Interest Expense, Net:
Interest Expense	$3,903		$3,522		$381
Interest and Miscellaneous Income	(218	)	(23	)	(195	)
Interest Expense, Net	$3,685		$   499		$186
	Six Months Ended September 30,				Change
	2004		2003
Interest Expense, Net:
Interest Expense	$1,890		$1,046		$844
Interest and Miscellaneous Income	(504	)	(62	)	(442	)
Interest Expense, Net	$1,386		$3,984		$402

Interest expense, net, consists of interest expense on debt, offset by interest earned on cash, cash equivalents, short-term investment balances, and other miscellaneous income. The most significant driver of the increase in interest expense, net in both fiscal 2005 periods related to an increase in interest expense, which resulted from higher interest rates on the Company’s outstanding debt during fiscal 2005 as compared to the prior year. A detailed discussion of the Company’s outstanding debt is included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2004 filed with the Securities and Exchange Commission on June 14, 2004 in the section of Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” titled, “Sources of Credit,” and in Note 6 to the Company’s consolidated financial statements, “Long-Term Debt.”

Income Tax Expense

The following table illustrates the changes in income tax expense for the three and six month periods ended September 30, 2004 and 2003, and provides a comparison of the effective income tax rates for the aforementioned periods:

(dollars in thousands)	Three Months Ended September 30,						Change			Percent Change
	2004			2003
Income Tax Expense	$	11,289		$	11,456		$	(167	)	-1.5	%
Effective Income Tax Rate		37.4	%		36.0	%
	Six Months Ended September 30,						Change			Percent Change
	2004			2003
Income Tax Expense	$	20,986		$	20,723		$	263		1.3	%
Effective Income Tax Rate		36.5	%		36.0	%

The Company provides for income tax expense on an interim basis based upon the Company’s estimate of the annual effective income tax rate. In determining the estimated annual effective income tax rate, the Company analyzes various factors, including projections of the Company’s annual earnings and the taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, the Company’s ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives. The effective income tax rates for the second quarters of fiscal 2005 and fiscal 2004 were 37.4% and 36.0%, respectively. For the first six months of fiscal 2005 and 2004, the effective income tax rates were 36.5% and 36.0%, respectively. The higher effective income tax rates during both periods resulted primarily from a reduction of operating profits generated in international tax jurisdictions and the resulting inability of the Company to fully utilize a portion of foreign tax credits against foreign profits taxed in the United States.

Business Segment Results of Operations

The Company operates and reports in three business segments: Healthcare, Life Sciences, and STERIS Isomedix Services. Note 12, “Business Segment Information,” to the Company’s consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on June 14, 2004, provides detailed information regarding each business segment. The following table provides a summary of the Company’s revenues by business segment for the three and six month periods ended September 30, 2004 and 2003:

(dollars in thousands)	Three Months Ended September 30,				Change			Percent Change
	2004		2003
Revenues:
Healthcare	$	187,071	$	179,672	$	7,399		4.1	%
Life Sciences		53,529		56,875		(3,346	)	-5.9	%
STERIS Isomedix Services		24,246		20,842		3,404		16.3	%

Healthcare Segment

Healthcare segment revenues represented 70.6% of total revenues for the second quarter of fiscal 2005 as compared to 69.8% of total revenues for the second quarter of fiscal 2004. Healthcare revenues increased $7.4 million, or 4.1%, to $187.1 million for the second quarter of fiscal 2005 as compared to $179.7 million for the second quarter of fiscal 2004. The increase in Healthcare revenues for the quarter was primarily driven by a 7.2% increase in capital revenues, which resulted from increased demand generated from recent hospital facility expansions and renovations which have shifted the segment’s revenues from smaller orders typically associated with the replacement of aging equipment to large-order, project-related capital equipment. At September 30, 2004, the Healthcare segment’s backlog amounted to $72.4 million, representing increases of $8.1 million, or 12.6%, and $15.0 million, or 26.0%, over the June 30, 2004 and September 30, 2003 levels, respectively. The Healthcare segment’s fiscal 2005 second quarter revenues also were positively impacted by a 2.4% increase in service revenues.

Healthcare segment revenues represented 69.9% of total revenues for the first half of fiscal 2005 as compared to 69.4% of total revenues for the first half of fiscal 2004. Healthcare revenues increased $4.5 million, or 1.2%, to $363.7 million for the first half of fiscal 2005 as compared to $359.2 million for the first half of fiscal 2004. Healthcare capital revenues remained flat for the six month period ended September 30, 2004 as compared to the same prior year period. Service revenues within the Healthcare segment increased 4.7%, year over year, and contributed to the overall increase in segment revenues.

Life Sciences Segment

Life Sciences segment revenues represented 20.2% of total revenues for the second quarter of fiscal 2005 as compared to 22.1% of total revenues for the second quarter of fiscal 2004. Life Sciences revenues decreased $3.3 million, or 5.9%, to $53.5 million for the second quarter of fiscal 2005 as compared to $56.9 million for the second quarter of fiscal 2004. The decrease in Life Sciences revenue for the quarter was driven by a 20.8% decrease in capital revenues. The decline was caused by a round of consolidations in the European pharmaceutical industry that led to the cancellation or delay of several new facility construction projects and more prevalent cautiousness in the North American market regarding capital spending. An increase in revenues throughout the Company’s Canadian and Asia Pacific markets partially offset the aforementioned revenue declines in Europe and North America. At September 30, 2004, backlog for the segment was $61.1 million, compared to backlogs of $69.1 million at June 30, 2004 and $95.2 million at September 30, 2003, indicating that weakness in capital sales may continue in the short term. An increase of $5.5 million, or 38.8%, in recurring revenue partially offset the segment’s quarter over quarter decline in capital revenues.

Life Sciences segment revenues represented 20.7% of total revenues for the first half of fiscal 2005 as compared to 22.4% of total revenues for the first half of fiscal 2004. Life Sciences revenues decreased $8.1 million, or 7.0%, to $107.2 million for the first half of fiscal 2005 as compared to $115.3 million for the first half of fiscal 2004. The decrease in Life Sciences revenues for the quarter was driven by an 18.2% decline in capital revenues, the reasons for which were presented in the previous paragraph. An increase of 23.2% in recurring revenues partially offset the segment’s year over year decline in capital revenues.

STERIS Isomedix Services Segment

STERIS Isomedix Services segment revenues represented 9.2% and 9.4% of total revenues for the three and six month periods ended September 30, 2004 as compared to 8.1% and 8.2% during the comparable prior year periods. The segment experienced revenue growth of 16.3% and 15.6%, respectively, for the three and six month periods ended September 30, 2004, as compared to the same periods in the prior year. The revenue growth in both periods presented is the result of increased demand and higher utilization of recently expanded facilities capacity in the segment.

The following table provides a summary of the Company’s operating results by business segment for the three and six month periods ended September 30, 2004 and 2003:

(dollars in thousands)	Three Months Ended September 30,						Change			Percent Change

NM - Not meaningful

To determine segment operating income (loss), the Company reduces the respective segment’s revenues by direct expenses and indirect cost allocations, which reflect the full allocation of all distribution, corporate, and research and development expenses. Corporate cost allocations are typically based on each segment’s portion of revenues, headcount, or other variables in relation to the total Company.

Healthcare Segment

Healthcare- Operating income for the second quarter of fiscal 2005 was flat, as compared to the same prior year period. Healthcare gross margins were 47.2% for the second quarter of fiscal 2005 as compared to 48.4% during the comparable prior year period, and were impacted by a shift in the mix of revenues toward capital equipment sales which carry lower margins. For the first half of fiscal 2005, the segment’s operating income was $56.4 million, representing an increase of $4.0 million, or 7.5%, as compared to the first half of fiscal 2004. The drivers of the increase in operating income for the first half of fiscal 2005, as compared to the first half of fiscal 2004 were more favorable gross margins and reduced operating expenses. Gross margin percentages in this business segment amounted to 47.9% and 47.5% for the first half of fiscal 2005 and 2004, respectively. Gross margins for the first half of fiscal 2005 reflect a greater proportion of higher margin service and consumable sales.

Life Sciences Segment

Life Sciences- Operating loss was $2.8 million and $7.5 million for the second quarter and first half of fiscal 2005, respectively. Although gross margins were relatively flat during both periods, as compared to the same prior year periods, the segment’s operating results were negatively impacted by reduced volumes and the resulting lower fixed cost absorption during the first two quarters of fiscal 2005 as compared to the prior year.

STERIS Isomedix Services Segment

STERIS Isomedix Services- Operating income increased $1.6 million, or 54.7%, to $4.7 million for the second quarter of fiscal 2005, as compared to $3.0 million during the second quarter of fiscal 2004. For the six month period ended September 30, 2004, the segment’s operating income was $9.9 million, representing an increase of $3.7 million, or 60.2%, over the comparable prior year period’s operating income of $6.2 million. The drivers of the increase in both periods were more favorable gross margins. Gross margins benefited from increased volume and improvements in processing efficiencies as a result of capital investments made during the past year.

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $61.4 million for the first six months of fiscal 2005 as compared to $29.5 million for the same prior year period. Significant components of the Company’s operating cash flows for the six months ended September 30, 2004 and 2003 driving the increase in net cash inflow from operating activities of $31.9 million include:

• Accounts receivables, net- Excluding the impact of foreign currency translation adjustments and businesses acquired, accounts receivable, net decreased $18.3 million and $11.5 million during the first half of fiscal 2005 and 2004, respectively. Accounts receivable balances are influenced by the timing of revenues and customer payments. For the first half of fiscal 2005, revenues were $519.6 million as compared to revenues of $570.3 million for the second half of fiscal 2004, resulting in an 8.9% decline. This decline, coupled with a 6 day reduction in days sales outstanding from 86 days at March 31, 2004 to 80 days at September 30, 2004, resulted in lower accounts receivable levels at September 30, 2004.

• Inventories- Excluding the impact of foreign currency translation adjustments and businesses acquired, inventories increased $3.2 million and $23.5 million during the first half of fiscal 2005 and 2004, respectively. The Company has typically established targeted inventory production levels at manufacturing facilities in a process called modified level-loading, whereby a relatively constant stream of inventory production occurs, which may result in varying inventory levels during the year as a result of customer demand fluctuations. During the second quarter of fiscal 2004, the Company’s inventory levels were impacted by stepped up production levels at certain manufacturing facilities in anticipation of increased third and fourth quarter demand, thus resulting in higher inventory levels.

• Accounts payable, net- Excluding the impact of foreign currency translation adjustments and businesses acquired, accounts payable decreased $8.0 million and $24.0 million during the first half of fiscal 2005 and 2004, respectively. Based upon varying payment due dates of accounts payable obligations and the Company’s cash management strategies, accounts payable balances may fluctuate from period to period.

24

• Accruals and other, net- Excluding the impact of foreign currency translation adjustments and businesses acquired, accruals and other, net decreased $14.4 million and increased $1.9 million during the first half of fiscal 2005 and 2004, respectively. Accruals and other, net decreased significantly during the first half of fiscal 2005 due to decreased accrued payroll and related liabilities that resulted from the timing of compensation related payments and reduced projected bonus payouts under the Company’s profit sharing plan. The decrease in accruals and other, net was further impacted by reduced employee and dealer commissions and deferred revenues as a result of changes in revenue mix and sales volumes.

Net Cash Used In Investing Activities

For the first six months of fiscal 2005, net cash used in investing activities amounted to $78.5 million as compared to $67.6 million during the same prior year period. The following discussion summarizes the significant components of the Company’s investing cash flows for the six months ended September 30, 2004 and 2003:

• Purchases of property, plant, equipment, and intangibles- During the first six months of fiscal 2005, the Company’s capital expenditures amounted to $25.5 million as compared to $27.8 million during the comparable prior year period. The Company continues to make investments in business expansion projects and information technology improvements.

• Investments in businesses, net of cash acquired- During the second quarter of fiscal 2005, the Company announced that it had acquired Albert Browne Limited (“Browne”). Investment in this business, net of cash acquired and other preliminary purchase accounting adjustments, amounted to $52.9 million. Further discussion of the Company’s acquisition of Browne is included in Note 2, “Business Acquisition.” Net cash flows used in investing activities for the first six months of fiscal 2004 reflect the acquisition of Hamo Holdings AG (“Hamo”) of $36.8 million. The Company announced this acquisition during the first quarter of fiscal 2004.

• Purchases of business related assets- During the first quarter of fiscal 2004, the Company acquired certain assets related to the sterilization container business from Sterion Incorporated for $2.9 million. The purchase of these assets is presented as cash used in investing activities for the six month period ended September 30, 2003.

Net Cash (Used In) Provided By Financing Activities

For the first six months of fiscal 2005, net cash used in financing activities amounted to $30.5 million as compared to net cash provided by financing activities of $25.2 million during the same prior year period. The following discussion summarizes the significant components of the Company’s financing cash flows for the six months ended September 30, 2004 and 2003:

• Net (payments) proceeds under credit facilities- During the first six months of fiscal 2005, net payments under credit facilities amounted to $2.2 million. During the first six months of fiscal 2004, net proceeds under the Company’s unsecured revolving credit facility amounted to $33.9 million. These borrowings were used by the Company to complete the acquisition of Hamo. A detailed description of the Company’s sources of credit is included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2004 filed with the Securities and Exchange Commission on June 14, 2004 in the section of Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” titled, “Sources of Credit,” and in Note 6, “Long-Term Debt,” to the consolidated financial statements. There have been no significant changes in the Company’s sources of credit since March 31, 2004.

• Repurchases of Common Shares- As discussed in Note 10, “Repurchases of Common Shares,” the Company’s Board of Directors has authorized the periodic repurchase of the Company’s Common Shares. From time to time, the Company engages in open market transactions to repurchase its Common Shares. During the first six months of fiscal 2005, the Company repurchased 1.5 million of its Common Shares for $33.9 million, representing an average purchase price of $22.01. During the first six months of fiscal 2004, the Company repurchased 0.6 million of its Common Shares for $14.1 million, representing an average purchase price of $22.08.

25

• Stock option and other equity transactions- Cash flows from stock option and other equity transactions are primarily derived from the issuance of the Company’s Common Shares under various employee stock compensation programs. During the first six months of fiscal 2005, cash proceeds, net of tax benefits, from the issuance of Common Shares under these programs totaled $4.3 million, as compared to $2.9 million during the comparable prior year period.

Cash Requirements

The Company believes that its available cash, cash flow from operations, and sources of credit will be adequate to satisfy its operating and capital needs for the next twelve months. The Company’s management and Board of Directors continually review the operating and capital requirements, as well as the overall capital structure of the Company.

Sources of Credit and Contractual and Commercial Commitments

A discussion of the Company’s sources of credit and contractual and commercial commitments is included in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2004, filed with the Securities and Exchange Commission on June 14, 2004. The Company’s sources of credit and contractual and commercial commitments have not changed materially from March 31, 2004. At September 30, 2004 and March 31, 2004, debt to capital amounted to 13.2% and 13.8%, respectively.

Critical Accounting Policies, Estimates, and Assumptions

A discussion of the Company’s critical accounting policies, estimates, and assumptions is included in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2004, filed with the Securities and Exchange Commission on June 14, 2004. The Company’s critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2004.

Contingencies

The Company is involved in various patent, product liability, consumer, commercial, environmental, tax proceedings and claims, government investigations, and other legal proceedings that arise from time to time in the ordinary course of business. In accordance with SFAS No. 5, “Accounting for Contingencies,” the Company records accruals for such contingencies to the extent that the Company concludes that their occurrence is both probable and estimable. The Company considers many factors in making these assessments, including the professional judgment of experienced members of management and the Company’s legal counsel. The Company has made estimates as to the likelihood of unfavorable outcomes and the amounts of such potential losses. Litigation is inherently unpredictable and actual results could differ from the Company’s estimates. The Company records anticipated recoveries under applicable insurance contracts when assured of recovery.

To the extent that management of the Company believes it is probable that a taxing authority will take a sustainable position on a matter contrary to the position taken by the Company, the Company provides tax accruals. If the Company prevails in matters for which accruals have been established or is required to pay amounts in excess of established accruals, the Company’s effective income tax rate in a given financial statement period may be materially impacted.

Refer to Part II, Item 1, “Legal Proceedings,” on page 29 of this Form 10-Q.

International Operations

The Company conducts operations outside of the United States through its subsidiaries in the same business segments as the Company’s domestic operations. Depending on the direction of change relative to the U.S. dollar, foreign currency values can increase or reduce the reported dollar value of the Company’s net assets and results of operations. Revenues were favorably impacted by $3.3 million, or 1.2%, and net income was negatively impacted by 0.2% during the second quarter of fiscal 2005 as compared to a favorable impact to revenues and net income of $4.3 million, or 1.7%, and $0.4 million, or 2.1%, respectively, during the comparable prior year period. Foreign currency fluctuations favorably impacted revenues during the first six months of fiscal 2005 by $5.1 million, or 1.0%, as compared to a favorable impact of $10.8 million, or 2.1%, during the comparable prior year period. Foreign currency fluctuations negatively impacted net income during the first six months of fiscal 2005 by $0.3 million, or 0.9%, as compared to a favorable impact of $0.9 million, or 2.4%, during the comparable prior year period.

Seasonality

The Company’s financial results have been subject to recurring seasonal fluctuations. A number of factors have contributed to the seasonal patterns, including sales promotion and compensation programs, customer capital equipment buying patterns, and international business practices. Sales and profitability of certain of the Company’s product lines have historically been disproportionately weighted toward the latter part of each quarter and generally weighted toward the latter part of each fiscal year. However, there is no assurance that these patterns will continue.

Forward-Looking Statements

This discussion may contain statements and data concerning certain trends, expectations, forecasts, estimates, or other forward-looking information affecting or relating to the Company or its industries that are intended to qualify for the protections afforded “forward-looking statements” under the Private Securities Litigation Reform Act of 1995 and other laws and regulations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

A discussion of market risk exposures is included in Part II, Item 7a, “Quantitative and Qualitative Disclosures about Market Risk,” of the Company’s Annual Report on Form 10-K for the year ended March 31, 2004 filed with the Securities and Exchange Commission on June 14, 2004. The Company’s exposures to market risk have not changed materially since March 31, 2004. During the second quarter of fiscal 2005, the Company began to manage its foreign currency risk by entering into forward contracts. These contracts are entered into in order to mitigate the impact of currency fluctuations on transactions and other exposures. The Company does not enter into forward contracts for speculative purposes.

27

ITEM 4. CONTROLS AND PROCEDURES

The Company’s management is responsible for establishing and maintaining effective disclosure controls and procedures, as defined under Rules 13a-15(e) and 15d-15(e) of the Securities and Exchange Act of 1934 (the “Exchange Act”). As of September 30, 2004, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the effectiveness of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s management, including the CEO and the CFO, concluded that the Company’s disclosure controls and procedures as of September 30, 2004 were effective in ensuring material information required to be disclosed in this Quarterly Report on Form 10-Q was recorded, processed, summarized, and reported on a timely basis. In addition, there were no changes in the Company’s internal control over financial reporting as defined under Exchange Act Rules 13a-15(f) and 15d-15(f) that occurred during the quarter ended September 30, 2004 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company is involved in a number of legal proceedings and claims which the Company believes arise from the ordinary course of its business, given its size, history, complexity, nature of its business, and industries in which it participates. These legal proceedings and claims generally involve a variety of legal theories and allegations, including without limitation, personal injury (e.g., slip and falls, automobile accidents), product liability (e.g., based on the operation or claimed malfunction of products), product exposure (e.g., claimed exposure to chemicals, asbestos, contaminants), property damage (e.g., claimed damage due to leaking equipment, fire), economic loss (e.g., breach of contract, other commercial claims), employment (e.g., wrongful termination), and other claims for damage and relief. In fiscal 2004, the Company settled a wrongful discharge lawsuit with a former employee. In connection with that settlement, the Company became aware of an investigation initiated based on discussions between the former employee and the FDA regarding the Company’s SYSTEM 1 ^® sterile processing system. The investigation is currently being conducted by the FDA and the U.S. Department of Justice and is ongoing. The Company has offered and intends to cooperate with the government agencies regarding this matter, if requested.

The Company believes it has adequately reserved for its current litigation and that the ultimate outcome of its pending lawsuits and claims will not have a material adverse effect on the Company’s consolidated financial position or results of operations taken as a whole. Due to their inherent uncertainty, however, there can be no assurance of the ultimate outcome of current or future litigation, proceedings, investigations, or claims or their effect. The Company presently maintains product liability insurance coverage and other liability coverage in amounts and with deductibles that it believes are prudent.

From time to time, STERIS is also involved in legal proceedings as a plaintiff involving contract, patent protection, and other claims asserted by the Company. Gains, if any, from these proceedings are recognized when they are realized. The Company believes there have been no material recent developments concerning the Company’s legal proceedings since March 31, 2004 and no new material pending legal proceedings required to be reported.

AMENDED AND RESTATED REGULATIONS

ARTICLE I

SHAREHOLDERS

Section 1. Annual Meeting. The annual meeting of the shareholders of the corporation for the election of directors, the consideration of reports to be laid before the meeting, and the transaction of such other business as may properly be brought before the meeting shall be held at the principal office of the corporation or at such other place either within or without the State of Ohio and/or in whole or in part by means of communications equipment (in the manner provided in Section 9 of this Article I), at such time and on such date as may be designated by the Board of Directors, the Chairman of the Board, or the President and specified in the notice of the meeting.

Section 2. Special Meetings. Special meetings of the shareholders of the corporation may be held on any business day when called by the Chairman of the Board, the President, a Vice President, the Board of Directors acting at a meeting, a majority of the directors acting without a meeting, or the persons who hold fifty percent of all the shares outstanding and entitled to vote at the meeting.

Upon request in writing delivered either in person or by registered mail to the President or the Secretary by any persons entitled to call a meeting of the shareholders, that officer shall forthwith cause to be given to the shareholders entitled thereto notice of a meeting to be held on the date not less than seven or more than sixty days after receipt of the request, as that officer may fix; if the notice is not given within thirty days after the delivery or mailing of the request, the persons calling the meeting may fix the time of the meeting and give notice thereof in the manner provided by law or as provided in these Regulations or cause the notice to be given by any designated representative. Each special meeting shall be called to convene between nine o’clock a.m. and five o’clock p.m., and shall be held at the principal office of the corporation unless the meeting is called by the directors, acting with or without a meeting, in which case the meeting may be held at any place either within or without the State of Ohio and/or in whole or in part by means of communications equipment (in the manner provided in Section 9 of this Article I) as may be designated by the Board of Directors and specified in the notice of the meeting.

Section 3. Notice of Meetings. Not less than seven or more than sixty days before the date fixed for a meeting of the shareholders, written notice stating the time, place, and purposes of the meeting shall be given by or at the direction of the Secretary, an Assistant Secretary, or any other person or persons required or permitted by these Regulations to give the notice. The notice shall be given to each shareholder entitled to notice of the meeting who is of record as of the day next preceding the day on which notice is given or, if a record date therefor is duly fixed, of record as of that date, by personal delivery or by mail, overnight delivery service, or any other means of communication authorized by the shareholder to whom the notice is given. If mailed or sent by overnight delivery, the notice shall be addressed to the shareholders at their respective addresses as they appear on the records of the corporation. If sent by another means of communication authorized by a shareholder, the notice shall be sent to the address furnished by the shareholder for such communications. Notice of the time, place, and purposes of any meeting of the shareholders may be waived in writing, either before or after the holding of the meeting, by any shareholder, which writing shall be filed with or entered upon the records of the corporation. Attendance of any shareholder at any meeting without protesting, prior to or at the commencement of the meeting, the lack of proper notice shall be deemed to be a waiver by the shareholder of notice of the meeting.

Section 4. Quorum; Adjournment. Except as may be otherwise provided by law or by the Articles of Incorporation, at any meeting of the shareholders the holders of shares entitling them to exercise a majority of the voting power of the corporation present in person, by proxy, or by the use of communications equipment shall constitute a quorum for the meeting, except that no action required by law, the Articles of Incorporation, or these Regulations to be authorized or taken by a designated proportion of the shares of any particular class or of each class of the corporation may be authorized or taken by a lesser proportion and except that the holders of a majority of the voting shares represented at the meeting, whether or not a quorum is present, may adjourn the meeting from time to time. If any meeting is adjourned, notice of adjournment need not be given if the time and place, if any, to which the meeting is adjourned and the means, if any, by which shareholders can be present and vote at the adjourned meeting through the use of communications equipment are fixed and announced at the meeting.

Section 5. Action Without a Meeting. Any action which may be authorized or taken at a meeting of the shareholders may be authorized or taken without a meeting with the affirmative vote or approval of, and in a writing or writings signed by or on behalf of, all of the shareholders who would be entitled to notice of a meeting of the shareholders held for the purpose, which writing or writings shall be filed with or entered upon the records of the corporation.

Section 6. Proxies. A person who is entitled to vote shares or to act with respect to shares may vote or act in person or by proxy and may appoint a proxy by a writing or verifiable communication authorized by the person. The person appointed as proxy need not be a shareholder. Unless the appointment of a proxy otherwise provides, the presence at a meeting of the person who appointed a proxy shall not operate to revoke the appointment. Notice to the corporation, in writing or in open meeting, of the revocation of the appointment of a proxy shall not affect any vote or act previously taken or authorized.

Section 7. Approval and Ratification of Acts of Officers and Directors. Except as otherwise provided by the Articles of Incorporation or by law, any contract, action, or transaction, prospective or past, of the corporation or of the Board of Directors or of any director or officer may be approved or ratified by the affirmative vote in person or by proxy of the holders of record of a majority of the shares held by persons not interested in the contract, action, or transaction and entitled to vote in the election of directors (without regard to voting powers which may thereafter exist upon a default, failure, or other contingency), which approval or ratification shall be as valid and binding as though affirmatively voted for or consented to by every shareholder of the corporation.

Section 8. Shareholder Proposals. No proposal made by a shareholder of the corporation shall be eligible to be submitted to the shareholders for their approval or adoption at any annual or special meeting of shareholders unless all of the following requirements are met:

(1) the shareholder submitting the proposal (the “proponent”) submits the proposal to the corporation in writing at the corporation’s principal executive offices;

(2) at the time the proponent submits such proposal the proponent is a shareholder of record of the corporation and continues to be a shareholder of record of the corporation as of the close of business on the record date for determining shareholders entitled to notice of and to vote at such annual or special meeting of shareholders, in both instances as reflected in the shareholder records of the corporation;

(3) at the time the proponent submits such proposal the proponent provides the corporation in writing with the proponent’s name, address, the number of voting securities held of record, the date upon which the proponent acquired such securities, and a list of all other proposals submitted by the proponent to the corporation during the preceding five years; and

(4) the proposal is received at the corporation’s principal executive offices (a) in the case of a proposal to be acted upon at an annual meeting of shareholders, not less than 120 calendar days in advance of the date of the previous year’s annual meeting of shareholders, or, if no annual meeting was held in the previous year, a reasonable time (as determined by the corporation in its sole discretion) before the current year’s annual meeting; and (b) in the case of a proposal to be acted upon at a special meeting of shareholders, a reasonable time (as determined by the corporation in its sole discretion) before the special meeting.

(5) Notwithstanding the foregoing provisions of this Section 8, in the case of any proposal that the corporation is required to include in its proxy statement and form of proxy under the provisions of Rule 14a-8 (as from time to time amended) promulgated under the Securities Exchange Act of 1934 (or any similar or successor rule or regulation under that or any successor act), compliance by the proponent with all of the requirements of such rule shall be deemed to constitute compliance with the provisions of this Section 8.

Section 9. Participation in Meeting by Means of Communications Equipment. The Board of Directors may determine that an annual or special meeting will not be held at any physical place, but instead will be held solely by means of communications equipment. The Board of Directors may also determine that shareholders and proxy holders who are not physically present at a meeting of shareholders that is held at a physical place may attend the meeting by use of communications equipment. In either such case, the communications equipment shall enable the shareholder or proxy holder to participate in the meeting and to vote on matters submitted to the shareholders, including an opportunity to read or hear the proceedings of the meeting and to speak or otherwise participate in the proceedings contemporaneously with those physically present. Any shareholder using communications equipment will be deemed present in person at the meeting. The Board of Directors may adopt guidelines and procedures for the use of communications equipment in connection with a meeting of shareholders to permit the corporation to verify that a person is a shareholder or proxy holder and to maintain a record of any vote or other action.

ARTICLE II

BOARD OF DIRECTORS

Section 1. Number; Term of Office. Commencing with the annual meeting of shareholders in 2005 and at all times thereafter, directors shall be elected at each annual meeting of shareholders for terms to expire at the next annual meeting of shareholders thereafter occurring. In each instance, directors shall hold office until their successors are chosen and qualified.

At the 2004 annual meeting of shareholders, the authorized number of members of the Board of Directors shall be nine. The Board of Directors or the shareholders may from time to time thereafter change the authorized number of members of the Board of Directors to a total number of no fewer than seven directors and no more than twelve directors. The shareholders may change the authorized number of members of the Board of Directors as provided in the immediately preceding sentence at a meeting of the shareholders called for the purpose of electing directors at which a quorum is present by the affirmative vote of the holders of a majority of the voting power represented at the meeting and entitled to elect the directors. The Board of Directors may change the authorized number of members of the Board of Directors by a vote of two-thirds of the directors then in office. Neither the provision for annual election of directors from and after the 2005 annual meeting of shareholders nor any reduction in the authorized number of directors shall of itself have the effect of shortening the term of any incumbent director.

Except as provided in the immediately preceding paragraph, the authorized number of directors may not be fixed or changed by the shareholders or directors, except (i) by amending these Regulations in accordance with the provisions of Article X of these Regulations, or (ii) pursuant to an agreement of merger or consolidation recommended by two-thirds of the members of the Board of Directors and adopted by the shareholders at a meeting held for such purpose by the affirmative vote of the holders of shares entitling them to exercise a majority of the voting power on such proposal.

This Section 1 and other provisions of these Regulations are subject to the provisions of the Articles of Incorporation with respect to special voting rights of holders of Preferred Shares in the event of certain defaults by the corporation in redeeming or paying dividends on such Preferred Shares.

Section 2. Election of Directors; Nominations; Vacancies. The directors shall be elected at each annual meeting of shareholders or at a special meeting called for the purpose of electing directors. Only persons who are nominated in accordance with the following procedures shall be eligible for election as directors. Nominations of persons for election as directors may be made at a meeting of shareholders by or at the direction of the Board of Directors by any nominating committee or person appointed by the Board of Directors, or by any shareholder of the corporation entitled to vote for the election of directors at the meeting who complies with the notice procedures set forth in this Section 2. Such nominations, other than those made by or at the direction of the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary of the corporation. To be timely, a shareholder’s notice shall be delivered to or mailed and received at the principal executive offices of the corporation not less than sixty (60) days nor more than ninety (90) days prior to the meeting; provided, however, that in the event that less than seventy-five (75) days’ notice to the shareholders or prior public disclosure of the date of the meeting is given or made, notice by the shareholder to be timely must be so received not later than the close of business on the fifteenth (15th) day following the earlier of the day on which such notice of the date of the meeting was mailed or such public disclosure was made. Such shareholder’s notice shall set forth (a) as to each person who is not an incumbent director when the shareholder proposes to nominate such person for election as a director: (i) the name, age, business address and residence address of such person; (ii) the principal occupation or employment of such person for the past five years; (iii) the class and number of shares of the corporation which are beneficially owned by such person; and (iv) any other information relating to such person that is required to be disclosed in solicitations for proxies for election of director pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended; and (b) as to the shareholder giving the notice: (i) the name and record address of such shareholder and (ii) the class and number of shares of the corporation which are beneficially owned by such shareholder. Such notice shall be accompanied by the written consent of each proposed nominee to serve as a director of the corporation, if elected. No person shall be eligible for election as a director of the corporation unless nominated in accordance with the procedures set forth in this Section 2.

The Chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the provisions of this Section 2, and if he should so determine, the defective nomination shall be disregarded.

- 3 -

In the event of the occurrence of any vacancy in the Board of Directors, however caused, or in the event of the creation of any director’s office by an increase in the number of directors, the remaining directors, though less than a majority of the whole authorized number of members of the Board of Directors, may, by the vote of two-thirds of their number, fill the vacancy or the newly created office, as the case may be, for the unexpired term.

Section 3. Resignations; Removal of Directors. The office of a director becomes vacant if the director dies or resigns. Any director may resign at any time by oral statement to that effect made at a meeting of the Board of Directors or in a writing to that effect delivered to the Secretary, which resignation shall take effect immediately or at such other time as the director may specify.

The Board of Directors may remove any director and thereby create a vacancy in the Board: (a) if by order of court the director has been found to be of unsound mind or if the director is adjudicated a bankrupt; (b) if within sixty days from the date of the director’s election the director does not qualify by accepting in writing the election to such office or by acting at a meeting of directors.

All the directors or any individual director, may be removed from office, without assigning any cause, by the vote of the holders of 75% of the voting power entitling them to elect directors in place of those to be removed. In case of any such removal, a new director may be elected at the same meeting for the unexpired term of each director removed. Failure to elect a director to fill the unexpired term of any director removed shall be deemed to create a vacancy in the Board. Any vacancy created by virtue of a resignation or removal under this Section 3 shall be filled by the Board in accordance with Section 2 hereof.

Section 4. Organization Meeting. Immediately after each annual meeting of the shareholders, the newly elected directors shall hold an organization meeting for the purpose of electing officers and transacting any other business. Notice of the organization meeting need not be given.

Section 5. Regular Meetings. Regular meetings of the Board of Directors may be held at such times and places within or without the State of Ohio or through any communications equipment if all persons participating can hear each other as may be provided for in bylaws or resolutions adopted by the Board of Directors and upon such notice, if any, as shall be so provided. Unless otherwise indicated in the notice of a regular meeting, any business may be transacted at that regular meeting.

Section 6. Special Meetings. Special meetings of the Board of Directors may be held at any time within or without the State of Ohio, or through any communications equipment if all persons participating can hear each other, upon call by the Chairman of the Board, the President, a Vice President, or any two directors. Notice of the place, if any, and time of each special meeting shall be given to each director either by personal delivery or by mail, telegram, cablegram, overnight delivery service, or any other means of communication authorized by the directors at least two days before the meeting, which notice need not specify the purposes of the meeting, except that attendance of any director at any special meeting, whether in person or through communications equipment, without protesting, prior to or at the commencement of the meeting, the lack of proper notice shall be deemed to be a waiver by the director of notice of the meeting and except that notice of a special meeting may be waived in writing, either before or after the holding of the meeting, by any director, which writing shall be filed with or entered upon the records of the corporation. Unless otherwise indicated in the notice of a special meeting, any business may be transacted at that special meeting.

Section 7. Quorum; Adjournment. A quorum of the Board of Directors at an organization, regular, or special meeting shall consist of at least two-thirds of the directors then in office. A majority of the directors present at a meeting duly held, whether or not a quorum is present, may adjourn the meeting from time to time; if any meeting is adjourned, notice of adjournment need not be given if the place, if any, and time to which the meeting is adjourned and the means, if any, by which directors can be present and participate in the meeting through the use of communications equipment, are fixed and announced at the meeting. At each meeting of the Board of Directors at which a quorum is present, all questions and business shall be determined by a vote of at least two-thirds of the directors then in office, except as in these Regulations otherwise expressly provided.

Section 8. Action Without a Meeting. Any action which may be authorized or taken at a meeting of the Board of Directors may be authorized or taken without a meeting with the affirmative vote or approval of, and in a writing or writings signed by, all of the directors, which writing or writings shall be filed with or entered upon the records of the corporation. A telegram, cablegram, electronic mail, or an electronic or other transmission capable of authentication that appears to have been sent by a director and that contains an affirmative vote or approval by the

- 4 -

director is a signed writing for the purposes of this Section 8. The date on which the telegram, cablegram, electronic mail, or electronic or other transmission is sent is the date on which the writing is signed.

Section 9. Committees. The Board of Directors may at any time appoint from its members an Executive, Finance, or other committee or committees, consisting of such number of members as the Board of Directors may deem advisable, together with such alternates as the Board of Directors may deem advisable, to take the place of any absent member or members at any meeting of the committee. Each member and each alternate shall hold office during the pleasure of the Board of Directors. Any committee shall act only in the intervals between meetings of the Board of Directors and shall have such authority of the Board of Directors as may, from time to time, be delegated by the Board of Directors, except the authority to fill vacancies in the Board of Directors or in any committee of the Board of Directors. Subject to these exceptions, any person dealing with the corporation shall be entitled to rely upon any act or authorization of an act by any committee to the same extent as an act or authorization of the Board of Directors. Each committee shall keep full and complete records of all meetings and actions, which shall be open to inspection by the directors. Unless otherwise ordered by the Board of Directors, any committee may prescribe its own rules for calling and holding meetings, including meetings by telephone or other communications equipment, and for its own method of procedure, and may act at a meeting, including a meeting by telephone or other communications equipment, by two-thirds of its members or without a meeting by a writing or writings signed by all of its members.

Members of the Board of Directors and members of any committee of the Board of Directors shall, as such, receive such compensation, which may be either a fixed sum for attendance at each meeting of the Board of Directors or at each meeting of the committee or stated compensation payable at intervals, or shall otherwise be compensated as may be determined by or pursuant to authority conferred by the Board of Directors or any committee of the Board of Directors, which compensation may be in different amounts for various members of the Board of Directors or any committee. No member of the Board of Directors and no member of any committee of the Board of Directors shall be disqualified from being counted in the determination of the presence of a quorum or from acting at any meeting of the Board of Directors or of a committee of the Board of Directors by reason of the fact that matters affecting the member’s own compensation as a director, member of a committee of the Board of Directors, officer, or employee are to be determined.

Section 2. Officers and Employees. The compensation of officers and employees of the corporation, or the method of fixing their compensation, shall be determined by or pursuant to authority conferred by the Board of Directors or any committee of the Board of Directors. Compensation may include pension, disability, and death benefits, and may be by way of fixed salary, on the basis of earnings of the corporation, any combination thereof, or otherwise, as may be determined or authorized from time to time by the Board of Directors or any committee of the Board of Directors.

Section 3. Transactions with Directors, Officers, and Employees. No contract, action, or transaction shall be void, or be voidable by the corporation, for the reason that it is between or affects the corporation and one or more of the directors, officers, or employees of the corporation or is between or affects the corporation and another corporation, partnership, joint venture, trust, or other enterprise in which one or more of the directors, officers, or employees of the corporation are directors, trustees, or officers or have a financial or personal interest or for the reason that one or more interested directors, officers, or employees of the corporation participate in or vote at the meeting of the Board of Directors or a committee of the Board of Directors that authorizes the contract, action, or transaction if, in any such case, the contract, action, or transaction is approved, ratified, or authorized in the manner prescribed in the Articles of Incorporation, these Regulations, or by law or if, in any such case, the contract, action, or transaction is fair as to the corporation as of the time it is authorized or approved by the directors, a committee of the Board of Directors, or the shareholders.

ARTICLE V

STANDARD OF CARE AND INDEMNIFICATION

Section 1. Standard of Care of Directors. A director of the corporation shall perform the director’s duties as a director, including the director’s duties as a member of any committee of the directors upon which the director may serve, in good faith, in a manner the director reasonably believes to be in or not opposed to the best interests of the corporation, and with the care that an ordinarily prudent person in a like position would use under similar circumstances. In performing a director’s duties a director is entitled to rely on information, opinions, reports, and statements that are prepared or presented by such person or persons and under such circumstances that the director’s reliance on the information, opinions, reports, or statements is at the time found warranted under the provision of the Ohio General Corporation Law. Other than in connection with an action or suit in which the liability of a director under Section 1701.95 of the Ohio Revised Code is the only liability asserted, a director shall not be found to have violated the director’s duties as specified under the preceding sentences of this Section unless it is proved by clear and convincing evidence in a court of competent jurisdiction that the director has not acted in good faith, in a manner the director reasonably believes to be in or not opposed to the best interests of the corporation, or with the

- 6 -

care that an ordinarily prudent person in a like position would use under similar circumstances, in any action brought against a director, including actions involving or effecting a change or potential change in control of the corporation, a termination or potential termination of the director’s service to the corporation, and the director’s service in any other position or relationship with the corporation.

Section 2. Limitation of Liability in Damages. Other than in connection with an action or suit in which the liability of a director under Section 1701.95 of the Ohio Revised Code is the only liability asserted, a person who is a director or officer of the corporation shall be liable in damages for any action the person takes or fails to take as a director or as an officer, as the case may be, only if it is proved by clear and convincing evidence in a court of competent jurisdiction that the person’s act or failure to act involved an act or omission either undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation.

Section 3. Third Party Action Indemnification. The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action, suit, or proceeding by or in the right of the corporation), by reason of the fact that the person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, or agent of another corporation, partnership, joint venture, employee benefit plan, trust, or other enterprise, against expenses (including attorney’s fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit, or proceeding unless it is proved by clear and convincing evidence in a court of competent jurisdiction that the person’s action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation and that, with respect to any criminal action or proceeding, the person had reasonable cause to believe the person’s conduct was unlawful; the termination of any action, suit, or proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, constitute proof.

Section 4. Derivative Action Indemnification. Other than in connection with an action or suit in which the liability of a director under Section 1701.95 of the Ohio Revised Code is the only liability asserted, the corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, or agent of another corporation, partnership, joint venture, employee benefit plan, trust, or other enterprise, against expenses (including attorney’s fees) actually and reasonably incurred by the person in connection with the defense or settlement of the action or suit unless it is proved by clear and convincing evidence in a court of competent jurisdiction that the person’s action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation, except that the corporation shall indemnify the person to the extent the court in which the action or suit was brought determines upon application that, despite the proof but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper.

Section 5. Determinations of Indemnification Rights. Any indemnification under Section 3 or Section 4 of this Article V (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee, or agent is proper in the circumstances. The determination shall be made (a) by a majority vote of those directors who, in number constitute a quorum of the directors and who also were not and are not parties to or threatened with any such action, suit, or proceeding or (b), if such a quorum is not obtainable (or even if obtainable) and a majority of disinterested directors so directs, in a written opinion by independent legal counsel (compensated by the corporation) or (c) by the affirmative vote in person or by proxy of the holders of record of a majority of the shares held by persons who were not and are not parties to or threatened with any such action, suit, or proceeding and entitled to vote in the election of directors without regard to voting power that may thereafter exist upon a default, failure, or other contingency or (d) by the court in which the action, suit, or proceeding was brought.

Section 6. Advances of Expenses. Unless the action or suit is one in which the liability of a director under Section 1701.95 of the Ohio Revised Code is the only liability asserted, expenses (including attorney’s fees) incurred by a director, officer, employee, or agent of the corporation in defending any action, suit, or proceeding referred to in Section 3 or Section 4 of this Article V shall be paid by the corporation, as they are incurred, in advance of final disposition of the action, suit, or proceeding upon receipt of an undertaking by or on behalf of the

- 7 -

director, officer, employee, or agent in which the person agrees both (a) to repay the amount if it is proved by clear and convincing evidence in a court of competent jurisdiction that the person’s action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation and (b) to cooperate with the corporation concerning the action, suit, or proceeding.

Section 7. Purchase of Insurance. The corporation may purchase and maintain insurance or furnish similar protection, including trust funds, letters of credit, and self-insurance, on behalf of or for any person who is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, or agent of another corporation, partnership, joint venture, employee benefit plan, trust, or other enterprise, against any liability asserted against the person and incurred by the person in any capacity, or arising out of the person’s status as such, whether or not the corporation would have the power to indemnify the person against liability under the provisions of this Article or of the Ohio General Corporation Law. Insurance may be purchased from or maintained with a person in which the corporation has a financial interest.

Section 8. Mergers. Unless otherwise provided in the agreement of merger pursuant to which there is a merger into this corporation of a constituent corporation that, if its separate existence had continued, would have been required to indemnify directors, officers, employees, or agents in specified situations, any person who served as a director, officer, employee, or agent of the constituent corporation, or served at the request of the constituent corporation as a director, trustee, officer, employee, or agent of another corporation, partnership, joint venture, employee benefit plan, trust, or other enterprise, shall be entitled to indemnification by this corporation (as the surviving corporation) to the same extent the person would have been entitled to indemnification by the constituent corporation if its separate existence had continued.

Section 9. Heirs; Non-Exclusivity. The limitation of liability in damages and the indemnification provided by this Article V shall continue as to a person who has ceased to be a director, officer, employee, or agent of the corporation and shall inure to the benefit of the heirs, executors and administrators of such a person and shall not be deemed exclusive of, and shall be in addition to, any other rights granted to a person seeking indemnification as a matter of law or under the Articles of Incorporation, these Regulations, any agreement, a vote of shareholders or disinterested directors, any insurance purchased by the corporation, any action by the directors to take into account amendments to the Ohio General Corporation Law that expand the authority of the corporation to indemnify a director, officer, employee, or agent of the corporation, or otherwise, both as to action in the person’s official capacity and as to action in another capacity while holding an office.

ARTICLE VI

RECORD DATES

For any lawful purpose, including, without limitation, the determination of the shareholders who are entitled to receive notice of or to vote at a meeting of the shareholders, the Board of Directors may fix a record date in accordance with the provisions of the Ohio General Corporation Law. The record date for the purpose of the determination of the shareholders who are entitled to receive notice of or to vote at a meeting of the shareholders shall continue to be the record date for all adjournments of the meeting unless the Board of Directors or the persons who shall have fixed the original record date shall, subject to the limitations set forth in the Ohio General Corporation Law, fix another date and shall cause notice thereof and of the date to which the meeting shall have been adjourned to be given to shareholders of record as of the newly fixed date in accordance with the same requirements as those applying to a meeting newly called. The Board of Directors may close the share transfer books against transfers of shares during the whole or any part of the period provided for in this Article, including the date of the meeting of the shareholders and the period ending with the date, if any, to which adjourned. If no record date is fixed therefor, the record date for determining the shareholders who are entitled to receive notice of or to vote at a meeting of the shareholders shall be the date next preceding the day on which notice is given or the date next preceding the day on which the meeting is held, as the case may be.

ARTICLE VII

CERTIFICATES FOR SHARES

Section 1. Form of Certificates and Signatures. Each holder of shares shall be entitled to one or more certificates, signed by the Chairman of the Board, the President, or a Vice President and by the Secretary, an Assistant Secretary, the Treasurer, or an Assistant Treasurer of the corporation, which shall certify the number and class of shares held by the shareholder in the corporation, but no certificate for shares shall be executed or delivered until the shares are fully paid. When a certificate is countersigned by an incorporated transfer agent or registrar, the

- 8 -

signature of any officer of the corporation may be facsimile, engraved, stamped, or printed. Although any officer of the corporation whose manual or facsimile signature is affixed to a certificate ceases to be that officer before the certificate is delivered, the certificate nevertheless shall be effective in all respects when delivered.

Section 2. Transfer of Shares. Shares of the corporation shall be transferable upon the books of the corporation by the holders thereof, in person, or by a duly authorized attorney, upon surrender and cancellation of certificates for a like number of shares of the same class or series, with duly executed assignment and power of transfer endorsed thereon or attached thereto, and with such proof of the authenticity of the signatures to such assignment and power of transfer as the corporation or its agents may reasonably require.

Section 3. Lost, Stolen, or Destroyed Certificates. The corporation may issue a new certificate for shares in place of any certificate theretofore issued by it and alleged to have been lost, stolen, or destroyed; the Board of Directors may, however, in its discretion, require the owner, or the owner’s legal representatives, to give the corporation a bond containing such terms as the Board of Directors may require to protect the corporation or any person injured by the execution and delivery of a new certificate.

Section 4. Transfer Agent and Registrar. The Board of Directors may appoint, or revoke the appointment of, transfer agents and registrars and may require all certificates for shares to bear the signatures of the transfer agents and registrars, or any of them.

ARTICLE VIII

AUTHORITY TO TRANSFER AND VOTE SECURITIES

The Chairman of the Board, the President, any Vice President, the Secretary, the Treasurer of the corporation, and each such officer are authorized to sign the name of the corporation and to perform all acts necessary to effect a sale, transfer, assignment, or other disposition of any shares, bonds, other evidences of indebtedness or obligations, subscription rights, warrants, or other securities of another corporation owned by the corporation and to issue the necessary powers of attorney; and each such officer is authorized, on behalf of the corporation, to vote the securities, to appoint proxies with respect thereto, to execute consents, waivers, and releases with respect thereto, or to cause any such action to be taken.

ARTICLE IX

CORPORATE SEAL

The Ohio General Corporation Law provides in effect that the absence of a corporate seal from any instrument executed on behalf of the corporation does not affect the validity of the instrument; if in spite of that provision a seal is imprinted on or attached, applied, or affixed to an instrument by embossment, engraving, stamping, printing, typing, adhesion, or other means, the impression of the seal on the instrument shall be circular in form and shall contain the name of the corporation and the words “corporate seal”.

ARTICLE X

AMENDMENTS

These Regulations may be amended, or new Regulations may be adopted, by the shareholders at a meeting held for that purpose, by the affirmative vote of the holders of shares entitling them to exercise a majority of the voting power on that proposal. Notwithstanding anything to the contrary contained in these Regulations or in this Article X, to amend or add to or repeal Article I—Section 2 and Section 8, Article II—Sections 2 and 3, and this Article X shall require the affirmative vote at a meeting of holders of shares entitled to exercise 75% of the voting power on such proposal, unless such action is recommended by two-thirds of the members of the Board of Directors.
