STERIS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

For the Three and Six Months Ended September 30, 2009 and 2008

(dollars
in thousands, except per share amounts)

1. Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations

STERIS Corporation, an Ohio corporation, develops, manufactures and markets infection prevention, contamination control, microbial reduction, and surgical and critical care support products and services for healthcare, pharmaceutical,
scientific, research, industrial, and governmental Customers throughout the world. As used in this Quarterly Report, STERIS Corporation and its subsidiaries together are called STERIS, the Company, we,
us, or our, unless otherwise noted.

We operate in three reportable business segments: Healthcare,
Life Sciences, and STERIS Isomedix Services (Isomedix). We describe our business segments in note 11 to our consolidated financial statements titled, Business Segment Information. Our fiscal year ends on March 31.
References in this Quarterly Report to a particular year or year-end mean our fiscal year. The significant accounting policies applied in preparing the accompanying consolidated financial statements of the Company are
summarized below:

Interim Financial Statements

We prepared the accompanying unaudited consolidated financial statements of the Company according to accounting principles generally accepted in the United States (U.S. GAAP) for interim
financial information and the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. This means that they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Our
unaudited interim consolidated financial statements contain all material adjustments (including normal recurring accruals and adjustments) management believes are necessary to fairly state our financial condition, results of operations, and cash
flows for the periods presented.

These interim consolidated financial statements should be read together with the
consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the Securities and Exchange Commission (SEC) on May 29, 2009. The Consolidated Balance
Sheet at March 31, 2009 was derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

Principles of Consolidation

We use the consolidation method to report our investment in our subsidiaries. Consolidation means that we combine the accounts of our wholly-owned subsidiaries with our accounts. Therefore, the accompanying consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiaries. We eliminate inter-company accounts and transactions when we consolidate these accounts.

Use of Estimates

We make certain estimates and assumptions when
preparing financial statements according to U.S. GAAP that affect the reported amounts of assets and liabilities at the financial statement dates and the reported amounts of revenues and expenses during the periods presented. These estimates and
assumptions involve judgments with respect to many factors that are difficult to predict and are beyond our control. Actual results could be materially different from these estimates. We revise the estimates and assumptions as new information
becomes available.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)(Continued)

For the Three and Six Months Ended September 30, 2009 and 2008

(dollars in thousands, except per share amounts)



This means that operating results for the three and six month periods ended September 30, 2009 are not necessarily indicative of results that may be expected for future quarters or for the
full fiscal year ending March 31, 2010.

Fair Value of Financial Instruments

The recorded value of financial instruments is approximately equal to the fair value. We estimate the fair value of our long-term debt using
discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. We determined that the recorded value of our long-term debt is approximately equal to the fair value at September 30, 2009
and March 31, 2009. The financial instruments that we hold could potentially expose us to a concentration of credit risk. We invest our excess cash in highly rated money market funds and other high-quality short-term investments placed with
major banks and financial institutions. We have established guidelines related to diversification and maturities to maintain safety and liquidity.

We provide additional information regarding the fair value of our financial instruments in note 17 titled, Fair Value Measurements.

Recently Adopted Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (FASB) issued a new standard to define fair value, establish a framework for measuring fair value in accordance with U.S. GAAP and
expand disclosures about fair value measurements. In February 2008, the FASB deferred the effective date of the standard for all nonfinancial assets and liabilities to fiscal years beginning after November 15, 2008. We adopted the required
provisions of the standard for financial assets and liabilities on April 1, 2008 and for nonfinancial assets and liabilities on April 1, 2009. The adoption did not have a material impact on our consolidated financial statements.

In December 2007, the FASB issued a new standard regarding the accounting for business combinations. The standard retains the
purchase method of accounting for acquisitions, but requires a number of changes, including changes in the way assets and liabilities are recognized in purchase accounting. It also changes the recognition of assets acquired and liabilities assumed
arising from contingencies, requires the capitalization of in-process research and development at fair value, and requires the expensing of acquisition-related costs as incurred. The changes will impact financial statements on the acquisition date
and in subsequent periods, as well as prior to the acquisition date because of the accounting treatment for acquisition-related costs. The provisions will be applied prospectively to business combinations completed in fiscal years beginning after
December 15, 2008.

In December 2007, the FASB issued a new standard regarding the accounting for noncontrolling
interests in consolidated financial statements. The standard recharacterizes minority interests as noncontrolling interests and requires these interests to be classified as a separate component of equity in our consolidated financial statements.
Purchases or sales of equity interests that do not result in a change in control will be accounted for as equity transactions. In addition, net income related to the noncontrolling interests will be included in our consolidated net income and, upon
a loss of control, the interest sold, as well as any interest retained, will be recorded at fair value with any gain or loss recognized in earnings. The provisions of the standard will be applied prospectively, except for the presentation and
disclosure requirements, which will apply retrospectively, and are effective for the first annual reporting period beginning after December 15, 2008. We adopted the standard as of

April 1, 2009, applying the presentation and disclosure requirements retrospectively resulting in reclassification of noncontrolling interests from Other liabilities to
Total equity. Income attributable to noncontrolling interests is included in Selling, general and administrative expenses in the Consolidated Statements of Income and is not material.

In March 2008, the FASB issued a new standard regarding disclosures about derivative instruments and hedging activities. The standard
requires disclosures regarding how and why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for, and how derivative instruments and related hedged items affect an entitys financial
position, results of operations, and cash flows. The standard is effective for fiscal years beginning after November 15, 2008, with early adoption permitted. We adopted the standard on April 1, 2009 and it did not have a material impact on
our consolidated financial statements.

In December 2008, the FASB issued a staff position regarding employers
disclosures about postretirement benefit plan assets. It requires us to disclose how investment allocation decisions are made, including the factors relevant to understanding investment policies and decisions, the major categories of plan assets,
the inputs and valuation techniques used to measure the fair value of the plan assets, the effect of fair value measurements using significant unobservable inputs (Level 3) on changes in plan assets for the period, and significant concentrations of
risk within plan assets. The provisions are effective for fiscal years ending after December 15, 2009 and will increase the disclosures in the notes to our consolidated financial statements related to the assets of defined benefit pension
plans.

In April 2008, the FASB issued a staff position which amends the factors that should be considered in developing
renewal or extension assumptions used to determine the useful life of a recognized intangible asset. The provisions apply prospectively to intangible assets acquired after the effective date in fiscal years beginning after December 15, 2008.
The adoption did not have a material impact on the consolidated financial statements.

In June 2008, the FASB issued a staff
position which provides that unvested share-based payment awards that contain rights to receive non-forfeitable dividends (whether paid or unpaid) are participating securities, and should be included in the two-class method of computed earnings per
share. The position is effective for fiscal years beginning after December 15, 2008, and interim periods within those years. The adoption did not have a material impact on our disclosure of earnings per share.

In April 2009, the FASB issued several staff positions related to the accounting and financial statement disclosures of financials
instruments that are effective for interim periods ending after June 15, 2009. All are to be applied prospectively and require comparative disclosures only for periods ending after initial adoption. The positions 1) change existing accounting
requirements for other than temporary impairment of debt securities, 2) provide guidance for valuation of assets and liabilities that have experienced a significant reduction in volume and activity in relation to normal market activity, and 3)
prospectively extend the disclosure requirements regarding the fair value of financial instruments, to interim financial statements. The adoption of these positions did not have a material impact on the consolidated financial statements.

In May 2009, the FASB issued a new standard requiring the disclosure of the date through which an entity has evaluated subsequent events
and the basis for that date. The provisions are effective for interim and annual periods ending after June 15, 2009. The adoption did not have a material impact on our consolidated financial statements.

For the Three and Six Months Ended September 30, 2009 and 2008

(dollars in thousands, except per share amounts)



In June 2009, the FASB issued a standard that establishes only two levels of U.S.
generally accepted accounting principles, authoritative and nonauthoritative. The FASB Accounting Standards Codification (the Codification) is now the sole source of authoritative, nongovernmental U.S. GAAP, except for rules and
interpretive releases of the SEC, which are sources of authoritative GAAP for SEC registrants. All other non-grandfathered, non-SEC accounting literature not included in the Codification will become nonauthoritative. This standard is effective for
financial statements for interim or annual reporting periods ending after September 15, 2009. As the Codification was not intended to change or alter existing GAAP, the adoption did not have any impact on our consolidated financial
statements.

Significant Accounting Policies

A detailed description of our significant and critical accounting policies, estimates, and assumptions is included in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the
SEC on May 29, 2009. Our significant and critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2009.

2. Restructuring

The following summarizes our restructuring plans
announced in prior fiscal years. We recognize restructuring expenses as incurred. In addition, we assess the property, plant and equipment associated with the related facilities for impairment. Additional information regarding our respective
restructuring plans is included in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on May 29, 2009.

Fiscal 2009 Restructuring Plan

During the third quarter of fiscal 2009, we adopted a restructuring plan
primarily focused on our international operations (the Fiscal 2009 Restructuring Plan). As part of this plan, we took actions to improve operations at our Pieterlen, Switzerland manufacturing facility, rationalized certain products,
recorded impairment charges for certain assets no longer used, and made targeted workforce reductions. We have closed two sales offices in Japan. These actions directly impacted approximately 100 employees worldwide. These restructuring actions are
intended to enhance our profitability and improve efficiency primarily by reducing ongoing international operating costs.

Since the inception of the Fiscal 2009 Restructuring Plan, we have incurred pre-tax expenses totaling $15,012 related to these actions, of which $4,441 was recorded as restructuring expenses and $10,571 was recorded in cost of revenues,
with expenses of $12,268 and $2,745 related to the Healthcare and Life Sciences reporting segments, respectively. We do not expect to incur significant additional expenses related to the Fiscal 2009 Restructuring Plan. We are continuing to evaluate
all of our operations for additional opportunities to improve performance, but we have not committed to any additional specific actions.

Fiscal 2008 Restructuring Plan

During the fourth quarter of fiscal 2008, we announced an expense reduction
initiative which was primarily focused on our North American operations, and was intended to enhance our profitability and improve efficiency by reducing ongoing operating costs (the Fiscal 2008 Restructuring Plan). We did not incur any
restructuring expenses related to the Fiscal 2008 Restructuring Plan in the three and six month periods ended September 30, 2009.

For the Three and Six Months Ended September 30, 2009 and 2008

(dollars in thousands, except per share amounts)



Since the inception of the Fiscal 2008 Restructuring Plan, we have incurred pre-tax
restructuring expenses totaling $14,333 related to these actions, of which $9,883 was recorded as restructuring expenses and $4,450 was recorded in cost of revenues, with restructuring expenses and cost of revenues of $11,856, $1,296, $429, and $752
related to the Healthcare, Life Sciences, and Isomedix reporting segments, and Corporate and other, respectively. We do not expect to incur any significant additional restructuring expenses related to the Fiscal 2008 Restructuring Plan.

European Restructuring Plan

During the third quarter of fiscal 2007, we adopted a restructuring plan related to certain of our European operations (the European Restructuring Plan). During the first quarter of fiscal 2009, we settled the remaining
obligations associated with this plan.

Fiscal 2006 Restructuring Plan

During fiscal 2006, we announced the transfer of the Erie, Pennsylvania manufacturing operations to Monterrey, Mexico and other restructuring
actions (the Fiscal 2006 Restructuring Plan), which were intended to improve our cost structure. We settled all obligations associated with this plan in fiscal 2009.

The following tables summarize our total restructuring expenses for the second quarter and first half of fiscal 2010 and fiscal 2009:

5. Inventories, Net

Inventories, net are stated at the lower of cost or market. We use 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 fiscal year-end LIFO
inventory valuation. Inventory costs include material, labor, and overhead. Inventories, net consisted of the following:

8. Income Tax Expense

Income tax expense includes United States federal, state and local, and foreign income taxes, and is based on reported pre-tax income. The
effective income tax rates from continuing operations for the three month periods ended September 30, 2009 and 2008 were 32.0% and 36.0%, respectively. For the six-month periods

(dollars in thousands, except per share amounts)



ended September 30, 2009 and 2008, the effective income tax rates from continuing operations were 33.9% and 31.0%, respectively. The lower effective income tax rate for the three month
period ended September 30, 2009 resulted principally from discrete item adjustments due to the settlement of certain tax years under examination in the United States.

Income tax expense is provided on an interim basis based upon our estimate of the annual effective income tax rate, adjusted each quarter
for discrete items. In determining the estimated annual effective income tax rate, we analyze various factors, including projections of our annual earnings and taxing jurisdictions in which the earnings will be generated, the impact of state and
local income taxes, our ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives.

As of March 31, 2009, we had $10,926 in unrecognized tax benefits, of which $2,223 would favorably impact the effective tax rate if recognized. As of September 30, 2009, we had $9,242 in unrecognized tax benefits, of which $699
would impact the effective tax rate if recognized. The decrease in unrecognized tax benefits for the three and the six month periods ended September 30, 2009 is primarily due to the settlement of certain tax years under examination in the
United States. We currently do not anticipate any significant increase or decrease in unrecognized tax benefits within 12 months of September 30, 2009. As of September 30, 2009, we have recognized a liability for interest of $778 and
penalties of $163.

We file income tax returns in the United States and in various state, local, and foreign jurisdictions.
For United States federal income tax purposes, we are closed through examination for years through fiscal 2007. With limited exceptions, we are no longer subject to state and local income tax examinations within the United States, or income tax
examinations outside the United States for years before fiscal 2005.

9. Benefit Plans

We provide 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, we sponsor an unfunded postretirement welfare benefits plan for two
groups of United States employees including the same employees who receive pension benefits under the United States defined benefit pension plans. Benefits under this plan include retiree life insurance and retiree medical coverage, including
prescription drug coverage. Additional information regarding our defined benefit pension plans and other postretirement benefits plan is included in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on
May 29, 2009.

We contribute amounts to the defined benefit pension plans at least sufficient to
meet the minimum requirements as stated in applicable employee benefit laws and local tax laws. We record liabilities for the difference between the fair value of the plan assets and the benefit obligation (the projected benefit obligation for
pension plans and the accumulated postretirement benefit obligation for other postretirement benefits plans) on our accompanying Consolidated Balance Sheets.

10. Contingencies

We are, and will likely continue to be, involved in a
number of legal proceedings, government investigations, and claims, which we believe generally arise in the course of our business, given our size, history, complexity, and the nature of our business, Customers, regulatory environment, and
industries in which we participate. These legal proceedings, government investigations, and claims generally involve a variety of legal theories and allegations, including, without limitation, personal injury (e.g., slip and falls, burns, vehicle
accidents), product liability or regulation (e.g., based on product operation or claimed malfunction, failure to warn, failure to meet specification, or failure to comply with regulatory requirements), product exposure (e.g., claimed exposure to
chemicals, asbestos, contaminants, radiation), property damage (e.g., claimed damage due to

leaking equipment, fire, vehicles, chemicals), economic loss (e.g., breach of contract, other commercial claims), financial (e.g., taxes, reporting), employment (e.g., wrongful termination,
discrimination, benefits matters), and other claims for damage and relief.

We record accruals for such contingencies to the
extent that we conclude that their occurrence is both probable and estimable. We consider many factors in making these assessments, including the professional judgment of experienced members of management and our legal counsel. We have estimated the
likelihood of unfavorable outcomes and the amounts of such potential losses. In managements opinion, the ultimate outcome of these proceedings and claims is not expected to have a material adverse effect on our consolidated financial position,
results of operations, or cash flows. However, the ultimate outcome of claims, litigation, and other proceedings is unpredictable and actual results could be materially different from our estimates. We record expected recoveries under applicable
insurance contracts when we are assured of recovery.

The United States Food and Drug Administration
(FDA) and the United States Department of Justice had been conducting an investigation to our knowledge since 2003 involving our STERIS SYSTEM 1® sterile processing system. We had received requests for documents, including the subpoena received in January 2005, and were aware of interviews of current and former
employees in connection with the investigation. We responded to these requests and cooperated with the government agencies regarding this matter. We were advised by the United States Attorneys Office for the Northern District of Ohio in May
2009 that it was declining to pursue the investigation.

On May 16, 2008, we received a warning
letter (the warning letter) from the FDA regarding our STERIS SYSTEM 1® sterile processor and the
STERIS 20 sterilant used with the processor (referred to collectively in the FDA letter and in this note as the device). We believe this warning letter arose from the previously disclosed investigation. In summary, the warning
letter included the FDAs assertion that significant changes or modifications have been made in the design, components, method of manufacture, or intended use of the device beyond the FDAs 1988 clearance, such that the FDA believes a new
premarket notification submission (known within FDA regulations as a 510(k) submission) should have been made. The warning letter referenced a number of changes to the device that, according to the FDA, require a new premarket notification
submission, and asserted that our failure to make such a submission resulted in violations of applicable law. The warning letter also requested documentation and explanation regarding various corrective actions related to the device prior to 2003,
and whether those actions should be considered corrections or removals requiring notice under applicable FDA regulations. On July 30, 2008 (with an Addendum on October 9, 2008), we provided a detailed response contending that the
assertions in the warning letter were not correct.

On November 4, 2008, we received a letter from the FDA (dated
November 3, 2008) in which the FDA stated without elaboration that, after reviewing our response, it disagreed with our position and that a new premarket notification submission is required. The agency did not address the removal and correction
reporting issues and invited a meeting with STERIS to discuss the warning letter, based on our earlier request. After discussions with the FDA regarding the November 3rd letter, we received an additional letter on November 6, 2008 from the
FDA. The November 6th letter stated that the intent of the November 3rd letter was to inform us of the FDAs preliminary disagreement with our response to the warning letter and, before finalizing a position, the FDA reiterated that
it wanted to meet with us to discuss the Companys response, issues related to the warning letter and next steps to resolve any differences between the Company and the FDA.

On January 20, 2009, we announced that we submitted to the FDA a new liquid chemical sterilization system for 510(k) clearance. The new
submission follows discussions with the FDA regarding the prior 510(k)

submission issues raised in the warning letter related to our existing device. The new liquid chemical sterilization system submitted to the FDA addresses the changes referenced by the FDA in the
warning letter and includes additional technology updates.

We communicated to Customers that STERIS will
continue supporting the existing STERIS SYSTEM 1® installed base by providing accessories, sterilant, service
and parts, and replacement processor units for at least a two year period. In the United States, STERIS is continuing sales of STERIS SYSTEM 1® processors only as replacements for existing units. Once the new liquid chemical sterilization system is cleared for market use by the FDA, we will work with
Customers to transition to the new product.

For fiscal 2009, this development did not have a material impact on our
consolidated financial results. Subsequent annualized revenues could be impacted by approximately $20,000 until the new product is cleared and commercialized.

We continue to believe that the changes described in the warning letter from the FDA do not significantly affect the
safety or effectiveness of the device and, therefore, did not and do not require a new premarket notification submission, and further, that the corrective actions were compliant with FDA regulations. However, if the FDAs assertions are
ultimately determined to be correct, the device would be considered adulterated and misbranded under United States law, in which case, we would be required to make a new premarket notification submission. The FDA also could take enforcement action
immediately without providing the opportunity to make a new 510(k) submission. If we did not make that 510(k) submission, if the FDA rejected that 510(k) submission, if the FDA took immediate enforcement action, or if governmental agencies and/or
third parties otherwise considered the device to be non-compliant, civil, administrative, or criminal proceedings could be initiated. These or other proceedings involving our STERIS SYSTEM 1® sterile processing system and the STERIS 20 sterilant, a significant product to us, could possibly result in judgments requiring re-labeling or restriction on
the manufacturing, sale, or distribution of products, or could require us to take other actions, including recalls, to pay fines or civil damages, or to be subject to other governmental or third party claims or remedies, which could materially
affect our business, performance, value, financial condition, and results of operations. We intend to continue our discussions with the FDA to seek resolution of all issues regarding the warning letter and any related investigation.

The STERIS SYSTEM 1® sterile processing system has been in use since its clearance by the FDA in the late 1980s. We estimate that the devices currently in operation are used by
approximately 5,000 users in excess of 30,000 times per day in the aggregate and that over 275 million medical instruments have been processed using the STERIS SYSTEM 1® sterile processing system. For additional information regarding this matter, see the following portions of our Annual Report on Form 10-K for the year ended
March 31, 2009 filed with the SEC on May 29, 2009: BusinessInformation with respect to our Business in GeneralRecent EventsGovernment Regulations, Risk FactorsWe are subject to extensive regulatory
requirements and must receive and maintain regulatory clearance or approval for many products and operations. Failure to receive or maintain, or delays in receiving, clearance or approvals may hurt our revenues, profitability, financial condition or
value, Risk FactorsWe may be adversely affected by product liability claims or other legal actions or regulatory or compliance matters, Risk FactorsMost of our products, including our new liquid chemical
sterilization system, must receive regulatory approvals before they can be marketed and sold in the United States and other countries, and Risk FactorsExisting and new Customers may not purchase or use the new liquid chemical
sterilization system consistent with the purchase and use of the existing STERIS SYSTEM 1®.

We believe we have adequately reserved for our current litigation and that the ultimate
outcome of pending lawsuits and claims will not have a material adverse affect on our 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, claims, proceedings, investigations, including the previously discussed investigation, or their effect. We presently maintain product liability insurance coverage, and other liability coverages in amounts and
with deductibles that we believe are prudent, but there can be no assurance that these coverages will be applicable or adequate to cover adverse outcomes of claims or legal proceedings against us. Additional information regarding our contingencies
is included in Item 2 of this Part I titled, Managements Discussion and Analysis of Financial Conditions and Results of Operations and in Item 1 of Part II titled, Legal Proceedings contained in this Quarterly
Report on Form 10-Q.

From time to time, STERIS is also involved in legal proceedings as a plaintiff involving contract,
patent protection, and other claims asserted by us. Gains, if any, from these proceedings are recognized when they are realized.

We are subject to taxation from United States federal, state, and local, and foreign jurisdictions. Tax positions are settled primarily through the completion of audits within each individual jurisdiction or the closing of a statute of
limitation. Changes in applicable tax law or other events may also require us to revise past estimates. We describe income taxes further in note 8 to our consolidated financial statements titled, Income Tax Expense and in our Annual
Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on May 29, 2009.

11. Business Segment Information

We operate and report in three business segments: Healthcare, Life Sciences, and Isomedix. Corporate and other,
which is presented separately, contains the Defense and Industrial business unit plus costs that are associated with being a publicly traded company and certain other corporate costs.

Our Healthcare segment manufactures and sells capital equipment, accessory, consumable, and service solutions to healthcare providers,
including acute care hospitals and surgery centers. These solutions aid our Customers in improving the safety, quality, and productivity of their surgical, sterile processing, gastrointestinal, and emergency environments.

Our Life Sciences segment manufactures and sells engineered capital equipment, formulated cleaning chemistries, and service solutions to
pharmaceutical companies, and public and private research facilities around the globe.

Our Isomedix segment operates through
a network of 20 facilities located in North America. We sell a comprehensive array of contract sterilization services using Gamma Irradiation, Electron Beam Irradiation, and Ethylene Oxide (EO) technologies. We provide sterilization,
microbial reduction, and materials modification services to companies that supply products to the healthcare, industrial, and consumer products industries.

Operating income (loss) for each segment is calculated as the segments gross profit less direct expenses and indirect cost allocations, which results in the full allocation of all distribution and
research and development expenses, and the partial allocation of corporate costs to the segments. These allocations are based upon variables such as segment headcount and revenues. In addition, the Healthcare segment is responsible for the
management of all but one manufacturing facility and uses standard cost to sell products to the Life Sciences segment.

Corporate and other includes the gross profit and direct expense of the Defense and Industrial business unit, as well as certain unallocated corporate costs. These costs include executive office
costs, Board of Directors compensation, shareholder services and investor relations, external audit fees and legacy pension and postretirement benefit costs from our former Erie manufacturing operations.

The accounting policies for reportable segments are the same as those for the consolidated Company. For the three and six month periods
ended September 30, 2009, revenues from a single Customer did not represent ten percent or more of any reportable segments revenues. Additional information regarding our segments is included in our Annual Report on Form 10-K for the year
ended March 31, 2009, filed with the SEC on May 29, 2009.

12. Common Shares

Basic earnings per common share are calculated based upon the weighted average number of common shares outstanding. Diluted earnings per common share are calculated based upon the weighted average number
of common shares outstanding plus the dilutive effect of common share equivalents calculated using the treasury stock method. The following table summarizes the determination of earnings available to common shareholders, common share and common
share equivalents outstanding used to calculate basic and diluted earnings per common share:

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 common share because the combined exercise prices, unamortized fair values, and assumed tax benefits upon exercise were greater than the average
market price for the common shares during the periods, so including these options would be anti-dilutive:

13. Repurchases of Common Shares

We obtained 10,566 of our common shares during the first six months of fiscal 2010 in connection with stock-based compensation award
programs. We did not repurchase any shares under the authorization provided by our Board of Directors. At September 30, 2009, $203,864 of STERIS common shares remained authorized for repurchase and 11,326,265 common shares were held in
treasury.

14. Share-Based Compensation

STERIS has a long-term incentive plan that makes available common shares for grants at the discretion of the Compensation Committee of the Board of Directors to officers, directors, and key employees in

stock options, restricted shares, restricted share units, and stock appreciation rights. Stock options provide the right to purchase our common shares at the market price on the date of grant,
subject to the terms of the option plans and agreements. Generally, one-fourth of the stock options granted become exercisable for each full year of employment following the grant date. Stock options granted generally expire 10 years after the grant
date, or earlier if the option holder is no longer employed by us. Certain option agreements have provisions that provide for an adjustment to the normal vesting schedule allowing the options to vest on a prorated basis as defined by the agreement
in the event of employee termination. Restricted shares and restricted share units generally cliff vest over an approximately three-year period. We generally use the common shares held in treasury for restricted share and share unit grants for the
stock option exercises on a first-in, first-out basis. As of September 30, 2009, 3,762,936 shares remain available for grant under the long-term incentive plan.

We estimate the fair value of share-based awards on the date of the grant using an option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense
over the requisite service periods in our Consolidated Statements of Income. The expense is classified as cost of goods sold or selling, general and administrative expenses in a manner consistent with the employees compensation and benefits.

The following weighted-average assumptions were used for share-based compensation granted during the first half of fiscal
2010 and fiscal 2009:



|                                 |  |             |  |

|                                 |  | Fiscal 2010 |  | Fiscal 2009
|Risk-free interest rate          |  | 1.89%       |  | 2.65%      
|Expected life of options         |  | 5.50 years  |  | 5.64 years 
|Expected dividend yield of stock |  | 1.49%       |  | 0.86%      
|Expected volatility of stock     |  | 27.96%      |  | 27.72%     

The risk-free interest rate is based upon the U.S. Treasury yield curve at the time
of grant. The expected life of options is reflective of historical experience, vesting schedules and contractual terms. The expected dividend yield of stock represents our best estimate of the expected future dividend yield. The expected volatility
of stock is derived by referring to our historical stock prices over a timeframe similar to that of the expected life of the grant. We applied estimated forfeiture rates of 2.39 percent and 2.86 percent during fiscal 2010 and 2009, respectively.
This rate is calculated based upon historical activity and represents an estimate of the granted options not expected to vest. If actual forfeitures differ from this calculated rate, we may be required to make additional adjustments to compensation
expense in future periods. The assumptions used above are reviewed at the time of each significant option grant, or at least annually.

Stock option activity for the first half of fiscal 2010 is as follows:

The aggregate intrinsic value in the table above represents the total pre-tax difference
between the $30.45 closing price of our common shares on September 30, 2009 over the exercise price of the stock option, multiplied by the number of options outstanding or outstanding and exercisable, as applicable. The aggregate intrinsic
value is not recorded for financial accounting purposes and the value changes daily based on the daily changes in the fair market value of our common shares.

The total intrinsic value of stock options exercised during the first half of fiscal 2010 and fiscal 2009 were $1,286 and $24,254, respectively. Net cash proceeds from the exercise of stock options were
$2,102 and $32,956 for the first half of fiscal 2010 and fiscal 2009, respectively. An income tax benefit of $463 and $8,732 was realized from stock option exercises during the first half of fiscal 2010 and fiscal 2009, respectively.

The weighted average grant date fair value of option grants was $5.66 and $8.78 for the first half of fiscal 2010 and fiscal 2009,
respectively.

Stock appreciation rights (SARS) were also granted during the first half of fiscal 2010. The 47,560
SARS granted carry generally the same terms and vesting requirements as stock options except that they are settled in cash upon exercise. The fair value of the SARS at the grant date was an aggregate amount of $263 and was determined utilizing the
same assumptions as those used for the valuation of stock options. The fair value of the outstanding SARS will be revalued at each reporting date and related expense will be adjusted appropriately.

Restricted share and restricted share unit activity for the first half of fiscal 2010 is as follows:

Restricted shares and restricted share units granted were valued based on the closing
stock price at the grant date and are estimated to cliff vest over an approximately three-year period based upon the terms of the grants. The value of restricted shares and restricted share units that vested during the first half of fiscal 2010 and
fiscal 2009 was $1,636 and $969, respectively, which is calculated as the number of restricted shares and restricted share units vested during the period multiplied by the weighted-average grant date fair value.

We granted 6,800 and 3,300 cash-settled restricted share units in the first half of fiscal 2010 and fiscal 2009, respectively. The fair
value of these restricted share units at the grant date was $155 and $102, respectively.

As of September 30, 2009, there
was $10,849 of total unrecognized compensation cost related to non-vested share-based compensation granted under our share-based compensation plans. We expect to recognize the cost over a weighted average period of 1.78 years.

15. Financial and Other Guarantees

We generally offer a limited parts and labor warranty on capital equipment. The specific terms and conditions of those warranties vary depending on the product sold and the country where we conduct business. We record a liability for the
estimated cost of product warranties at the time product revenues are recognized.

The amounts we expect to incur on behalf of our Customers for the future estimated cost of these warranties are recorded as a current liability on the accompanying Consolidated Balance Sheets
within Accrued expenses and other. Factors that affect the amount of our warranty liability include the number and type of installed units, historical and anticipated rates of product failures, and material and service costs per claim.
We periodically assess the adequacy of our recorded warranty liabilities and adjust the amounts as necessary.

Changes in our
warranty liability during the first half of fiscal 2010 were as follows:



|                                    |  |   |        |

|                                    |  |   |        |  

We also sell product maintenance contracts to our Customers. These contracts range in
terms from one to five years and require us to maintain and repair the product over the maintenance contract term. We initially record amounts due from Customers under these contracts as a liability for deferred service contract revenue on the
accompanying Consolidated Balance Sheets within Accrued expenses and other. The liability recorded for such deferred service revenue was $19,275 and $17,477 as of September 30, 2009 and March 31, 2009, respectively. Such
deferred revenues are then amortized on a straight-line basis over the contract term and recognized as service revenues on the accompanying Consolidated Statements of Income. The activity related to the liability for deferred service contract
revenues has been excluded from the table presented above.

16. Forward Contracts

From time to time, we enter into forward contracts to hedge potential foreign currency gains and losses that arise from transactions
denominated in foreign currencies, including inter-company transactions. We also enter into forward contracts to hedge price changes in commodities that impact raw materials included in our cost of revenues. We do not use derivative financial
instruments for speculative purposes. These contracts are not designated as hedging instruments and do not receive hedge accounting treatment; therefore, changes in their fair value are not deferred but are recognized immediately in the Consolidated
Statements of Income.

17. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or that would be paid to transfer a liability in an orderly
transaction between market participants at the measurement date. We estimate the fair value of financial instruments using available market information and generally accepted valuation methodologies. The inputs used to measure fair value are
classified into three tiers. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable;
and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring the entity to develop its own assumptions. The following table shows our financial assets and liabilities accounted for at fair value on a
recurring basis at September 30, 2009:



|                                |  |                                                    |       |                                                     |   |                               |  |   |     |  |   |

|(2) | We provide a domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of compensation for an employee-specified term
or until retirement or termination. Amounts deferred can be allocated to various hypothetical investment options. We hold investments to satisfy the future obligations of the plan. Changes in the value of the investment accounts are recognized each
period based on the fair value of the underlying investments. Employees making deferrals are entitled to receive distributions of their account balances (amounts deferred, together with earnings (losses)).

18. Subsequent Events

We
have evaluated events occurring subsequent to September 30, 2009 through November 3, 2009, the date of issuance of these consolidated financial statements, to determine whether they require recognition or disclosure in the consolidated
financial statements. Based upon this evaluation, we have determined that no material subsequent events occurred that require recognition or disclosure in the financial statements, except for a special dividend authorized by the Board of Directors
of $2.00 per common share payable December 22, 2009 to shareholders of record on November 24, 2009.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

STERIS
Corporation

We have reviewed the consolidated balance sheet of STERIS Corporation and subsidiaries as of September 30,
2009, and the related consolidated statements of income for the three and six-month periods ended September 30, 2009 and 2008, and the consolidated statements of cash flows for the six-month periods ended September 30, 2009 and 2008. 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 upon our review, 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, 2009, 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 May 29, 2009, 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, 2009, 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
|------- | -------------------------------------------------------------------------------------

Introduction

In
Managements Discussion and Analysis of Financial Condition and Results of Operations (the MD&A), we explain the general financial condition and the results of operations for STERIS including:



| |  |  | what factors affect our business;
| | - |  | ---------------------------------



| |  |  | what our earnings and costs were in each period presented;
| | - |  | ----------------------------------------------------------



| |  |  | why those earnings and costs were different from the prior periods;
| | - |  | -------------------------------------------------------------------



| |  |  | where our earnings came from;
| | - |  | -----------------------------



| |  |  | how this affects our overall financial condition; and
| | - |  | -----------------------------------------------------



| |  |  | where cash will come from to pay for future capital expenditures.
| | - |  | -----------------------------------------------------------------

As you read the MD&A, you should refer to information in our consolidated financial statements, which present the results of our
operations for the second quarter and first half of fiscal 2010 and fiscal 2009. It may also be helpful to read the MD&A in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on May 29, 2009. In the
MD&A, we analyze and explain the period-over-period changes in the specific line items in the Consolidated Statements of Income. Our analysis may be important to you in making decisions about your investments in STERIS.

Financial Measures

In the
following sections of the MD&A, we may, at times, refer to financial measures that are not required to be presented in the consolidated financial statements under U.S. GAAP. We sometimes use the following financial measures in the context of
this report: backlog; debt-to-total capital; net debt-to-total capital; and days sales outstanding. We define these financial measures as follows:



| |  |  | Backlog  We define backlog as the amount of unfilled capital equipment purchase orders at a point in time. We use this figure as a measure to
assist in the projection of short-term financial results and inventory requirements.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Debt-to-total capital  We define debt-to-total capital as total debt divided by the sum of total debt and shareholders equity. We use this
figure as a financial liquidity measure to gauge our ability to borrow, fund growth, and measure the risk of our financial structure.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net debt-to-total capital  We define net debt-to-total capital as total debt less cash (net debt) divided by the sum of net debt and
shareholders equity. We also use this figure as a financial liquidity measure and to measure the risk of our financial structure.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Days sales outstanding (DSO)  We define DSO as the average collection period for accounts receivable. It is calculated as net
accounts receivable divided by the trailing four quarters revenues, multiplied by 365 days. We use this figure to help gauge the quality of accounts receivable and expected time to collect.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the following sections of MD&A, we may, at times, also refer to financial measures which are considered to be non-GAAP
financial measures under the rules of the SEC. Non-GAAP financial measures we may use are as follows:



| |  |  | Free cash flow  We define free cash flow as net cash flows provided by operating activities as presented in the Consolidated Statements of Cash
Flows less purchases of property, plant, equipment, and intangibles, net, plus proceeds from the sale of property, plant, equipment, and intangibles, which is also presented in the Consolidated Statements of Cash Flows. We use this measure to gauge
our ability to fund future growth outside of core operations, repurchase common shares, pay cash

We may, at times, refer to our results of operations excluding certain transactions
or amounts that are non-recurring or are not indicative of future results, in order to provide meaningful comparative analysis between the periods presented. For example, when discussing changes in revenues, we may, at times, exclude the impact of
recently completed acquisitions.

We present these financial measures because we believe that understanding these additional
factors underlying our performance provides meaningful analysis of our financial performance. These financial measures should not be considered alternatives to measures required by U.S. GAAP. Our calculations of these measures may be different from
the calculations of similar measures used by other companies and you should be careful when comparing these financial measures to those of other companies.

Revenues  Defined

As required by Regulation S-X under the Securities
Exchange Act of 1934 (Regulation S-X), we separately present revenues generated as either product revenues or service revenues on our Consolidated Statements of Income for each period presented. When we discuss revenues, we may, at
times, refer to revenues summarized differently than the Regulation S-X requirements. The terminology, definitions, and applications of terms that we use to describe revenues may be different from terms used by other companies. We use the following
terms to describe revenues:



| |  |  | Revenues  We present revenues net of sales returns and allowances.
| | - |  | -------------------------------------------------------------------



| |  |  | Product Revenues  We define product revenues as revenues generated from sales of capital equipment, which includes steam and low
temperature liquid sterilizers, washing systems, VHP® technology, water stills, and pure steam generators;
integrated OR; 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  We define service revenues as revenues generated from parts and labor associated with the maintenance, repair,
and installation of our capital equipment, as well as revenues generated from contract sterilization offered through our Isomedix segment.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Capital Revenues  We define capital revenues, a subset of product revenues, as revenues generated from sales of capital equipment,
which includes steam and low temperature liquid sterilizers, washing systems, VHP® technology, water stills, and
pure steam generators; surgical lights and tables; and integrated OR.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Consumable Revenues  We define consumable revenues, a subset of product revenues, 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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

General Company Overview and Executive Summary

Our mission is to provide a healthier today and safer tomorrow through knowledgeable people and innovative infection prevention,
decontamination and health science technologies, products, and services. Our dedicated employees around the world work together to supply a broad range of solutions by offering a combination of equipment, consumables, and services to healthcare,
pharmaceutical, industrial, and governmental Customers.

The bulk of our revenues are derived from the healthcare and
pharmaceutical industries. Much of the growth in these industries is driven by the aging of the population throughout the world, as an increasing number of individuals are entering their prime healthcare consumption years, and is dependent upon
advancement in healthcare delivery, acceptance of new technologies, government policies, and general economic conditions. In addition, each of our core industries also benefits from specific trends that contribute toward demand. Within healthcare,
there is increased concern regarding the level of hospital-acquired infections around the world. The pharmaceutical industry has been impacted by increased regulatory scrutiny of cleaning and validation processes, mandating that manufacturers
improve their processes. In the contract sterilization industry, where our Isomedix segment competes, the aging population increases the demand for medical procedures, which increases the consumption of single use medical devices and surgical kits.

Fiscal 2010 second quarter and first half revenues were $314.2 million and $597.8 million, respectively, representing
decreases of 2.8% and 5.8%, driven by declines in all three reportable business segments. Our gross margin percentages were 42.2% and 43.1% for the second quarter and first half of fiscal 2010, which was an increase of 120 basis points compared to
the same prior year quarter and an increase of 170 basis points from the first half of fiscal 2009. Gross margins during both fiscal 2010 periods benefited from price increases, lower raw material costs and favorable foreign currency fluctuations.

Free cash flow was $74.4 million in the first half of fiscal 2010 compared to $57.3 million in the prior year first half,
reflecting an increase in cash earnings during fiscal 2010 and improved cash flow from operating assets and liabilities. Our debt-to-total capital ratio was 20.8% at September 30, 2010 as compared to 22.6% at March 31, 2009, reflecting no
additional borrowings and increased operating income. We also declared and paid cash dividends totaling $0.22 per common share in the first half of fiscal 2010. In the first half of fiscal 2009, we declared and paid cash dividends totaling $0.14 per
common share.

Additional information regarding the Companys fiscal 2010 second quarter and first half financial
performance is included in the subsection below titled Results of Operations.

Matters Affecting Comparability

Restructuring. During the second quarter and first half of fiscal 2010, we did not incur any significant additional pre-tax
expenses related to previously announced restructuring actions, and we settled certain obligations for less than originally expected.

Additional information regarding our restructuring actions is included in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on May 29, 2009.

International Operations.Since we conduct operations outside of the United States using various foreign currencies, our
operating results are impacted by foreign currency movements relative to the U.S. dollar. During the second quarter of fiscal 2010, our revenues were unfavorably impacted by $3.5 million, or 1.1%, and income before taxes was favorably impacted by
$2.1 million, or 4.9%, as a result of foreign currency movements relative to the U.S. dollar. During the first half of fiscal 2010, our revenues were unfavorably impacted by $10.0 million, or 1.7%, and income before taxes was favorably impacted by
$5.3 million, or 6.7%, as compared to the same prior year period.

Quarter over Quarter Comparison

Revenues decreased $8.9 million, or 2.8%, to $314.2 million for the quarter ended September 30, 2009, as compared to $323.1 million for
the comparable prior year quarter. Capital equipment revenues decreased 8.6% as a result of decreased sales within the United States, Europe and the Asia Pacific region offset by growth in the Latin America region. Recurring revenues increased 1.2%,
with an increase of 8.8% in consumable revenues partially offset by a decrease in service revenues of 3.5%, primarily driven by growth in United States consumables and declines in United States services.

International revenues decreased $2.1 million, or 2.6%, to $75.9 million, for the quarter ended September 30, 2009, as compared to
$78.0 million for the comparable prior year quarter. International revenues were negatively affected by declines in capital equipment revenues, which decreased 2.2% primarily due to decreases within Europe for both our Healthcare and Life Sciences
segments. International recurring revenues also fell during the second quarter of fiscal 2010 by 3.1%, driven by a decline of 5.7% in service revenues. We experienced declines in service revenues in Canada, Europe and the Asia Pacific region.

United States revenues decreased $6.8 million, or 2.8%, to $238.3 million, for the quarter ended September 30, 2009, as
compared to $245.1 million for the comparable prior year quarter. The decrease in United States revenues reflects a 11.7% decrease in capital equipment revenues. United States recurring revenues increased 2.2% with an 11.6% increase in consumable
revenues partially offset by a decrease of 3.1% in service revenues. The prior period service revenues include revenues from two Isomedix facilities sold in fiscal 2009.

First Half over First Half Comparison

Revenues decreased
$36.9 million, or 5.8%, to $597.8 million for the first half of fiscal 2010, as compared to $634.7 million during the first half of fiscal 2009. Capital equipment revenues decreased 15.4%, primarily driven by weaker demand within the United States
in all reportable business segments. Recurring revenues increased less than 1.0%.

International revenues for the first half
of fiscal 2010 were $135.7 million, a decrease of $12.7 million, or 8.5%, as compared to the first half of fiscal 2009. Fiscal 2010 year-to-date international revenues were negatively impacted by an 11.3% decrease in capital equipment revenue and a
decline of 5.5% in recurring revenues, reflecting declines in both consumable and service revenues.

United States revenues
for the first half of fiscal 2010 were $462.1 million, a decrease of $24.3 million, or 5.0%, as compared to the first half of fiscal 2009. The fiscal 2010 year-to-date decrease in United States revenues was primarily driven by our Healthcare
segment, with a 20.0% decrease in capital equipment revenues. United States recurring revenues grew 1.8% as an 11.9% growth in consumable revenues was offset by a decline in service revenues of 3.9%. The service revenue decline included a reduction
in revenues resulting from the fiscal 2009 sale of two Isomedix facilities.

Our gross profit (margin) is affected by the volume, pricing, and mix of our products
and services, as well as the costs associated with the products and services that are sold. Gross margin for the second quarter of fiscal 2010 amounted to 42.2%, representing an increase of 120 basis points as compared to the same prior year period.
For the first half of fiscal 2010, gross margin amounted to 43.1%, representing an increase of 170 basis points as compared to the same prior year period. During both fiscal 2010 periods, we benefited from price increases, lower raw material costs,
and foreign currency fluctuations.

NM - Not Meaningful

Significant components of total selling, general, and
administrative expenses (SG&A) are compensation and benefit costs, fees for professional services, travel and entertainment, facilities costs, and other general and administrative expenses. As a percentage of total revenues, SG&A
decreased 20 basis points to 23.7% for the second quarter of fiscal 2010 and decreased 100 basis points to 24.9% for the first half of fiscal 2010, as compared to the same prior year periods. The decrease in SG&A in both fiscal 2010 periods
reflects improved operating expense leverage and the benefit of efficiency initiatives previously implemented. Included in the fiscal 2009 second quarter and first half SG&A results is a $2.1 million gain on the sale of an Isomedix facility
located in the Chicago, Illinois area to a privately held Customer.

As a percentage of total revenues, research and
development expenses were 2.6% for each of the three and six month periods ended September 30, 2009, as compared to 2.5% and 2.6%, respectively, for the same prior year periods. For the three month period ended September 30, 2009, research
and development expenses increased 1.5% to $8.2 million as compared to $8.1 million during the same prior year period. The second quarter of fiscal 2010 includes a government subsidy of $0.8 million received for research and development expenses
incurred by one of our international locations. For the first half of fiscal 2010, research and development expenses decreased 3.5% to $15.8 million, as compared to $16.3 million, during the same prior year period. Research and development expenses
are influenced by the number and timing of in-process projects and labor hours and other costs associated with these projects. Our research and development initiatives continue to emphasize new product development, product improvements, and the
development of new technological innovations. During the second quarter and first half of fiscal 2010, our investments in research and development continued to be focused on, but were not limited to, enhancing capabilities of new chemistries and
delivery systems for disinfection and sterilization, sterile processing combination technologies, surgical tables and accessories, and the areas of emerging infectious agents such as Prions and Nanobacteria.

Our operating expenses include restructuring expenses. We recognize restructuring expenses as incurred. In addition, we assess the property,
plant and equipment associated with the related facilities for impairment.

The total pre-tax restructuring expenses recorded
during the second quarter and first half of fiscal 2010 and fiscal 2009 are summarized in the following tables:

Income tax expense includes United States federal, state and local, and foreign

respectively, for the same prior year periods. The lower effective income tax rate for the second quarter of fiscal 2010 resulted principally from discrete item adjustments due to the settlement of certain tax years under examination in the United
States.

We record income tax expense during interim periods based on our estimate of the annual effective income tax rate,
adjusted each quarter for discrete items. We analyze various factors to determine the estimated annual

year period. Healthcare revenues decreased $4.8 million, or 2.1%, to $223.0 million for the quarter ended September 30, 2009, compared with $227.8 million for the second quarter of the prior year. Consumable revenues increased 6.7% in part
because of increased demand for our products. This increase was more than offset by declines in revenues from capital equipment and service of 6.4% and 3.3%, respectively. At September 30, 2009, the Healthcare segments backlog amounted to
$129.9 million, decreasing $2.5 million, or 1.9%, compared to the backlog of $132.4 million at June 30, 2009 and increasing $5.8 million, or 4.7%, compared to the backlog of $124.1 million at September 30, 2008.

Healthcare segment revenues represented 70.9% of total revenues for the first six months of fiscal 2010 compared with 71.2% for the same
prior year period. Healthcare revenues decreased $28.3 million, or 6.3%, to $423.6 million for the six months ended September 30, 2009, as compared to $451.9 million for the same prior year period. The decrease is primarily attributed to lower
capital equipment and service revenues within the United States, which decreased 14.9% and 4.5% respectively. Consumable revenue grew 6.6%, primarily within the United States and Europe.

Life Sciences Segment

Life Sciences segment revenues represented 17.3% of total revenues for the second quarter of fiscal 2010 compared with 17.7% for the same
prior year period. Life Sciences revenues decreased $2.8 million, or 4.8%, to $54.4 million for the quarter ended September 30, 2009, as compared to $57.2 million for the second quarter of the prior year. Consumable revenues grew 17.7% as
demand in the United States increased. This increase was more than offset by decreases in capital equipment and service revenues of 19.2% and 2.8%, respectively. Capital equipment revenues continue to be impacted by project delays, by our
pharmaceutical and research customers. At September 30, 2009, the Life Sciences segments backlog amounted to $46.5 million, a decrease of $0.3 million, or 0.7%, compared to the backlog of $46.2 million at June 30, 2009 and a decrease
of $2.2 million, or 4.5%, compared to the backlog of $48.7 million at September 30, 2008.

Life Sciences segment revenues
represented 16.8% of total revenues for the first six months of fiscal 2010, compared with 16.6% for the same prior year period. Life Sciences revenues decreased $4.7 million, or 4.4%, to $100.5 million for the first half of fiscal 2010, as compared
to $105.2 million for the same prior year period. The decrease in Life Sciences revenues was primarily driven by a 17.5% decrease in capital equipment revenues reflecting declines in all geographic regions but most significantly in Europe. The
declines reflect continued project delays by our pharmaceutical and research customers. Recurring revenues grew 4.5% with consumable revenues growth of 14.0% partially offset by a decline in service revenues of 2.5%.

Operating income (loss) for each segment is calculated as
the segments gross profit less direct expenses and indirect cost allocations, which results in the full allocation of all distribution and research and development expenses, and the partial allocation of corporate costs to the segments. These
allocations are based upon variables such as segment headcount and revenues. In addition, the Healthcare segment is responsible for the management of all but one manufacturing facility and uses standard cost to sell products to the Life Sciences
segment. Corporate and other includes the gross profit and direct expense of the Defense and Industrial business unit, as well as certain unallocated corporate costs. These costs include executive office costs, Board of Directors compensation,
shareholder services and investor relations, external audit fees and legacy pension and postretirement benefit costs from our former Erie manufacturing operations.

Healthcare Segment

The Healthcare segments operating
income increased $3.7 million and $6.5 million for the second quarter and first six months of fiscal 2010, respectively, as compared to the same prior year periods. The segments operating margins were 16.3% and 16.2% for the second quarter and
first half of fiscal 2010, respectively, representing increases of 190 basis points and 250 basis points, respectively, as compared to prior year periods. The improvement in operating income was driven by efficiency initiatives, lower raw material
costs and favorable foreign currency exchange fluctuations.

Life Sciences Segment

The Life Sciences segments operating income increased $2.3 million and $6.0 million for the second quarter and first six months of
fiscal 2010, respectively, as compared to the same prior year periods. The segments operating margins were 15.7% and 13.3% for the second quarter and first half of fiscal 2010, respectively, representing increases of 480 basis points and 640
basis points, respectively, over the comparable prior year periods. The improvement was driven by operating efficiencies.

Isomedix
Segment

The Isomedix segments operating income decreased $2.8 million and $2.7 million for the second
quarter and first six months of fiscal 2010, respectively, as compared to the same prior year periods. The segments operating margins were 21.3% and 22.4% for the second quarter and first half of fiscal 2010, representing decreases of 630
basis points and 250 basis points, respectively, over the comparable prior year periods. Included in the segments fiscal 2009 second quarter and first half operating income is a $2.1 million gain on the sale of a facility located in the
Chicago, Illinois area to a privately held Customer.

Net Cash Provided by Operating Activities.The net cash provided by our
operating activities was $92.4 million for the first six months of fiscal 2010 compared with $68.7 million for the first six months of fiscal 2009. The following discussion summarizes the significant changes in our operating cash flows:

Non-cash items  Our non-cash items include depreciation, depletion, and amortization, share-based compensation expense, changes in
deferred income taxes, and other items. Non-cash items were $32.9 million for the first six months of fiscal 2010 compared with $34.6 million for the first six months of fiscal 2009. Significant changes in these items for the first half of fiscal
2010 as compared to the same prior year period are summarized below:



| |  |  | Depreciation, depletion, and amortization  Depreciation, depletion, and amortization are the most significant component of non-cash items. This
expense totaled $27.8 million and $29.6 million for the first six months of fiscal 2010 and 2009, respectively.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Share-based compensation expense  We recorded share-based compensation expense of $4.0 million and $3.8 million for the first six months of
fiscal 2010 and fiscal 2009, respectively.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deferred income taxes- Our deferred income tax benefits increased $2.1 million for the first half of fiscal 2010, compared with a decrease of $3.8
million for the first half of fiscal 2009 due to the timing and recognition of settlements and changes in provisions.

Changes in operating assets and liabilities  Changes to our operating assets and
liabilities amounted to a positive $1.8 million and a negative $20.2 million during the first six months of fiscal 2010 and fiscal 2009, respectively. Significant changes in the first half of fiscal 2010 as compared to the first half of fiscal 2009
are summarized below:



| |  |  | Accounts receivable, net  Changes in our net accounts receivable balances provided cash of $31.0 million and $34.2 million during the first six
months of fiscal 2010 and fiscal 2009, respectively. Our accounts receivable balances may change from period to period due to the timing of revenues and customer payments.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Inventories, net  Decreases in our net inventory balances provided cash of $9.1 million for the first six months of fiscal 2010 whereas increases
in our net inventory balance drove uses of cash of $19.3 million during the first six months of fiscal 2009. Inventory balances in fiscal 2010 reflect lower raw material costs, lower production levels and the impact of foreign exchange rate
fluctuations.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Prepaid expenses and other current assets  Our other current assets primarily consist of prepaid expenses for insurance, taxes, and other general
corporate items. Changes in our other current asset balances provided cash of $1.2 million and $13.5 million for the first six months of fiscal 2010 and 2009, respectively. The higher amount during the first half of fiscal 2009 was primarily a
result of the application of taxes on deposit with the IRS toward the settlement of certain tax years under examination.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts payable, net  Decreases in our net accounts payable balances drove uses of cash of $13.6 million and $8.5 million during the first six
months of fiscal 2010 and fiscal 2009, respectively. Cash flows related to accounts payable may change from period to period due to varying payment due dates and other terms of our accounts payable obligations.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accruals and other, net  Changes in our net accruals and other liabilities balances drove uses of cash of $25.9 million and $40.1 million during
the first six months of fiscal 2010 and fiscal 2009, respectively. The higher cash usage in the first half of fiscal 2009 primarily reflects payments made in fiscal 2009 against amounts accrued in fiscal 2008 for incentive compensation and
severance, and the payment of income taxes previously accrued. Cash flows related to our accruals and other liabilities balances will change from period to period due to the timing of accruals and payments under our incentive compensation programs.
Accruals under our various incentive compensation programs rise during the course of the fiscal year and decline significantly in the first fiscal quarter as payments are made under these programs. Changes in accruals for deferred revenues also
contribute to the increase or decrease in these balances.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Net Cash Used In Investing Activities.The net cash we used in investing activities totaled $18.0 million for the first six months of fiscal 2010 compared with $11.4 million for the first six months of fiscal 2009. The following discussion summarizes the significant changes in
our investing cash flows for the first half of fiscal 2010 as compared to the first half of fiscal 2009:



| |  |  | Purchases of property, plant, equipment, and intangibles, net- Capital expenditures were $18.5 million for the first half of fiscal 2010 compared with
$20.9 million during the same prior year period.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Proceeds from the sale of property, plant, equipment, and intangibles  During the first six months of fiscal 2010, we recorded proceeds of $0.5
million. During the prior year, we recorded proceeds of $9.5 million related to the sale of an Isomedix facility located in the Chicago, Illinois area to a privately-held Customer.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Net Cash (Used In) Provided By Financing Activities.The net cash used in financing activities totaled $10.6 million for the
first six months of fiscal 2010 compared with net cash provided by our financing activities of $53.5 million for the first six months of fiscal 2009. The following discussion summarizes the significant changes in our financing cash flows for the
first half of fiscal 2010 as compared to the first half of fiscal 2009:



| |  |  | Proceeds from the issuance of long-term obligations  We did not issue additional debt during fiscal 2010, whereas, $150.0 million of senior notes
were issued in fiscal 2009 in an offering that was exempt
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | from the registration requirements of the Securities Act of 1933. Proceeds from the senior notes issued during the second quarter of fiscal 2009 were used in part to repay amounts outstanding
under our revolving credit facility. The senior notes allowed the Company to lock-in favorable long-term rates. Amounts borrowed are generally used to fund common share repurchases and working capital changes, and for other corporate purposes.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net proceeds under credit facilities  We did not engage in any credit facility transactions during fiscal 2010, however, during fiscal 2009, the
Company repaid $79.2 million under a revolving credit facility.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Repurchases of common shares  We obtained 10,566 of our common shares during the first six months of fiscal 2010 in connection with stock-based
compensation award programs. We did not repurchase any shares under the authorization provided by our Board of Directors. During the first half of fiscal 2009, we paid for the repurchase of 1,645,900 of our common shares at an average purchase price
of $30.51 per common share.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash dividends paid to common shareholders  During the first six months of fiscal 2010 and fiscal 2009, we paid cash dividends totaling $0.22 and
$0.14 per outstanding common share, respectively. Total cash dividends paid during the first half of fiscal 2010 and fiscal 2009 amounted to $12.9 million and $8.3 million, respectively.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock option and other equity transactions, net  We receive cash for issuing common shares under our various employee stock option programs.
During the first six months of fiscal 2010 and 2009, we received cash proceeds totaling $2.1 million and $33.0 million, respectively, under these programs.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Tax benefit from stock options exercised  During the first half of fiscal 2010 and fiscal 2009, our income taxes were reduced by $0.5 million and
$8.7 million, respectively, as a result of deductions allowed for stock options exercised.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Cash Flow
Measures.Free cash flow was $74.4 million in the first half of fiscal 2010 compared to $57.3 million in the prior year first half, reflecting an increase in cash earnings in fiscal 2010 and improved cash flow from operating assets and
liabilities. Our debt-to-total capital ratio was 20.8% at September 30, 2009 and 22.6% at March 31, 2009.

Sources of Credit and Contractual and Commercial Commitments.Information related to our sources of credit and contractual and commercial commitments is included in our Annual Report on Form 10-K for the year
ended March 31, 2009, filed with the SEC on May 29, 2009. Our commercial commitments were approximately $31.4 million at September 30, 2009 reflecting a net decrease of $1.2 million in surety bonds and other commercial commitments
from March 31, 2009. Except as described, our contractual commitments have not changed materially from March 31, 2009. The maximum aggregate borrowing limits under our revolving credit facility (Facility) have not changed since
March 31, 2009. At September 30, 2009, the maximum amount available for borrowing under this Facility was $374.8 million. The maximum aggregate borrowing limit of $400.0 million under the Facility is reduced by outstanding borrowings and
letters of credit issued under a sub-limit within the Facility ($25.2 million at September 30, 2009). The Facility matures on September 13, 2012.

Cash Requirements.Currently, we intend to use our existing cash and cash equivalent balances, cash generated from operations, and our existing credit facilities for short-term
and long-term capital expenditures and our other liquidity needs. We believe that these amounts will be sufficient to meet working capital needs, capital requirements, and commitments for at least the next twelve months. However, our capital
requirements will depend on many uncertain factors, including our rate of sales growth, our Customers acceptance of our products and services, the costs of obtaining adequate manufacturing capacities, the timing and extent of our research and
development projects, and changes in our operating expenses. To the extent that our existing sources of cash are not sufficient to fund our future activities, we may need to raise additional funds through additional borrowings or selling equity
securities. We cannot assure you that we will be able to obtain additional funds on terms favorable to us, or at all.

Critical Accounting Policies, Estimates, and Assumptions

Information related to our critical accounting policies, estimates, and assumptions is included in our Annual Report on Form 10-K for the
year ended March 31, 2009, filed with the SEC on May 29, 2009. Our critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2009.

Contingencies

We are
involved in various patent, product liability, consumer, commercial, environmental, tax proceedings and claims, governmental investigations, and other legal and regulatory proceedings that arise from time to time in the ordinary course of our
business. We record a liability for such contingencies to the extent that we conclude that their occurrence is both probable and estimable. We consider many factors in making these assessments, including the professional judgment of experienced
members of management and our legal counsel. We have made estimates as to the likelihood of unfavorable outcomes and the amounts of such potential losses. In our opinion, the ultimate outcome of these proceedings and claims is not anticipated to
have a material adverse affect on our consolidated financial position, results of operations, or cash flows. However, the ultimate outcome of claims, litigation, and other proceedings is unpredictable and actual results could be materially different
from our estimates. We record anticipated recoveries under applicable insurance contracts when assured of recovery. Refer to Part II, Item 1, Legal Proceedings for additional information.

We are subject to taxation from United States federal, state and local, and foreign jurisdictions. Tax positions are settled primarily
through the completion of audits within each individual tax jurisdiction or the closing of a statute of limitation. Changes in applicable tax law or other events may also require us to revise past estimates. The IRS routinely conducts audits of our
federal income tax returns. In the first quarter of fiscal 2009, we reached a settlement with the IRS for all material tax matters for fiscal 2002 through fiscal 2005. In the second quarter of fiscal 2010, we reached a settlement with the IRS on all
material tax matters for fiscal 2006 through fiscal 2007. We remain subject to tax authority audits in various other jurisdictions in which we operate. If we prevail in matters for which accruals have been recorded, or are required to pay amounts in
excess of recorded accruals, our effective income tax rate in a given financial statement period could be materially impacted.

International Operations

Since we conduct operations outside the United States using various foreign
currencies, our operating results are impacted by foreign currency movements relative to the U.S. dollar. During the second quarter of fiscal 2010, our revenues were unfavorably impacted by $3.5 million, or 1.1%, and income before taxes was
favorably impacted by $2.1 million, or 4.9%, when compared to the same period in fiscal 2009, as a result of foreign currency movements relative to the U.S. dollar. During the first half of fiscal 2010, our revenues were unfavorably impacted by
$10.0 million, or 1.7%, and income before taxes was favorably impacted by $5.3 million, or 6.7%, when compared to the same period in fiscal 2009, as a result of foreign currency movements relative to the U.S. dollar. We cannot predict future changes
in foreign currency exchange rates or the effect they will have on our operations.

that transition, labor, competition, timing, execution, regulatory, governmental, or other issues or risks associated with our business, industry, or other issues, activities, or initiatives, including any impacting the sterilization system
currently in use or the ability to obtain clearance or market acceptance of the new sterilization system, may adversely impact our performance, results, or value, and (g) the effect of the credit crisis on our ability, as well as the ability of
our Customers and suppliers, to adequately access the credit markets when needed, and (h) those risks described in our Annual Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on May 29, 2009, under

|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Under the supervision of and with the participation of our management, including the Principal Executive Officer (PEO) and Principal Financial Officer (PFO), we evaluated the effectiveness of the design and operation
of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as of the end of the period covered by this Quarterly Report. Based on that evaluation, including the
assessment and input of our management, the PEO and PFO concluded that, as of the end of the period covered by this Quarterly Report, our disclosure controls and procedures were effective.

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the
Securities Exchange Act of 1934, that occurred during the quarter ended September 30, 2009 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART IIOTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

We
are, and will likely continue to be involved in a number of legal proceedings, government investigations, and claims, which we believe generally arise from the ordinary course of our business, given our size, history, complexity, and the nature of
our business, Customers, regulatory environment, and industries in which we participate. These legal proceedings, investigations and claims generally involve a variety of legal theories and allegations, including, without limitation, personal injury
(e.g., slip and falls, burns, vehicle accidents), product liability or regulation (e.g., based on product operation or claimed malfunction, failure to warn, failure to meet specification, or failure to comply with regulatory requirements), product
exposure (e.g., claimed exposure to chemicals, asbestos, contaminants, radiation), property damage (e.g., claimed damage due to leaking equipment, fire, vehicles, chemicals), economic loss (e.g., breach of contract, other commercial claims),
financial (e.g., taxes, reporting), employment (e.g., wrongful termination, discrimination, benefits matters), and other claims for damage and relief.

The FDA and the United States Department of Justice had been conducting an investigation to our knowledge since 2003 involving our STERIS SYSTEM 1® sterile processing system. We had received requests for documents, including the subpoena received in January 2005, and were aware of interviews of current and former
employees in connection with the investigation. We responded to these requests and cooperated with the government agencies regarding this matter. We were advised by the United States Attorneys Office for the Northern District of Ohio in May
2009 that it was declining to pursue the investigation.

On May 16, 2008, we received a warning
letter (the warning letter) from the FDA regarding our STERIS SYSTEM 1® sterile processor and the
STERIS 20 sterilant used with the processor (referred to collectively in the FDA letter and in this Item 3 as the device). We believe this warning letter arose from the previously disclosed investigation. In summary, the
warning letter included the FDAs assertion that significant changes or modifications have been made in the design, components, method of manufacture, or intended use of the device beyond the FDAs 1988 clearance, such that the FDA
believes a new premarket notification submission (known within FDA regulations as a 510(k) submission) should have been made. The warning letter referenced a number of changes to the device that, according to the FDA, require a new premarket
notification submission, and asserted that our failure to make such a submission resulted in violations of applicable law. The warning letter also requested documentation and explanation regarding various corrective actions related to the device
prior to 2003, and whether those actions should be considered corrections or removals requiring notice under applicable FDA regulations. On July 30, 2008 (with an Addendum on October 9, 2008), we provided a detailed response contending
that the assertions in the warning letter were not correct.

On November 4, 2008, we received a letter from the FDA
(dated November 3, 2008) in which the FDA stated without elaboration that, after reviewing our response, it disagreed with our position and that a new premarket notification submission is required. The agency did not address the removal and
correction reporting issues and invited a meeting with STERIS to discuss the warning letter, based on our earlier request. After discussions with the FDA regarding the November 3rd letter, we received an additional letter on November 6,
2008 from the FDA. The November 6th letter stated that the intent of the November 3rd letter was to inform us of the FDAs preliminary disagreement with our response to the warning letter and, before finalizing a position, the FDA
reiterated that it wanted to meet with us to discuss the Companys response, issues related to the warning letter and next steps to resolve any differences between the Company and the FDA.

On January 20, 2009, we announced that we submitted to the FDA a new liquid chemical sterilization system for 510(k) clearance. The new
submission follows discussions with the FDA regarding the prior 510(k) submission issues raised in the warning letter related to our existing device. The new liquid chemical sterilization system submitted to the FDA addresses the changes referenced
by the FDA in the warning letter and includes additional technology updates.

##### Table of Contents

We communicated to Customers that STERIS will continue supporting the
existing STERIS SYSTEM 1® installed base by providing accessories, sterilant, service and parts, and replacement
processor units for at least a two year period. In the United States, STERIS is continuing sales of STERIS SYSTEM 1® processors only as replacements for existing units. Once the new liquid chemical sterilization system is cleared for market use by the FDA, we will work with Customers to transition to the new product.

For fiscal 2009, this development did not have a material impact on our consolidated financial results. Subsequent annualized revenues could
be impacted by approximately $20.0 million until the new product is cleared and commercialized.

We
continue to believe that the changes described in the warning letter from the FDA do not significantly affect the safety or effectiveness of the device and, therefore, did not and do not require a new premarket notification submission, and further,
that the corrective actions were compliant with FDA regulations. However, if the FDAs assertions are ultimately determined to be correct, the device would be considered adulterated and misbranded under United States law, in which case, we
would be required to make a new premarket notification submission. The FDA also could take enforcement action immediately without providing the opportunity to make a new 510(k) submission. If we did not make that 510(k) submission, if the FDA
rejected that 510(k) submission, if the FDA took immediate enforcement action or if governmental agencies and/or third parties otherwise considered the device to be non-compliant, civil, administrative, or criminal proceedings could be initiated.
These or other proceedings involving our STERIS SYSTEM 1® sterile processing system and STERISs S20TM
sterilant, a significant product to us, could possibly result in judgments requiring re-labeling or restriction on the manufacturing, sale, or distribution of products, or could require us to take other actions, including recalls, to pay fines or
civil damages, or to be subject to other governmental or third party claims or remedies, which could materially affect our business, performance, value, financial condition, and results of operations. We intend to continue our discussions with the
FDA to seek resolution of all other issues regarding the warning letter and any related investigation.

The STERIS SYSTEM 1® sterile processing system has been in use since its clearance by the FDA in the
late 1980s. We estimate that the devices currently in operation are used by approximately 5,000 users in excess of 30,000 times per day in the aggregate and that over 275 million medical instruments have been processed using the STERIS
SYSTEM 1® sterile processing system. For additional information regarding this matter, see the following
portions of our Annual Report on Form 10-K for the year ended March 31, 2009 filed with the SEC on May 29, 2009: BusinessInformation with respect to our Business in GeneralRecent EventsGovernment Regulations,
Risk FactorsWe are subject to extensive regulatory requirements and must receive and maintain regulatory clearance or approval for many products and operations. Failure to receive or maintain, or delays in receiving, clearance or
approvals may hurt our revenues, profitability, financial condition or value, Risk FactorsWe may be adversely affected by product liability claims or other legal actions or regulatory or compliance matters, Risk
FactorsMost of our products, including our new liquid chemical sterilization system, must receive regulatory approvals before they can be marketed and sold in the United States and other countries, and Risk FactorsExisting
and new Customers may not purchase or use the new liquid chemical sterilization system consistent with the purchase and use of existing SYSTEM 1®.

We believe we have adequately
reserved for our current litigation and that the ultimate outcome of pending lawsuits and claims will not have a material adverse affect on our 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, claims, proceedings, investigations, including the previously discussed investigation, or their effect. We presently maintain product liability
insurance coverage, and other liability coverages in amounts and with deductibles that we believe are prudent, but there can be no assurance that these coverages will be applicable or adequate to cover adverse outcomes of claims or legal proceedings
against us.

From time to time, STERIS is also involved in legal proceedings as a plaintiff involving contract, patent
protection, and other claims asserted by us. Gains, if any, from these proceedings are recognized when they are realized.
