STERIS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

For the Three and Nine Months Ended December 31, 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. This means that operating results for the three and nine month periods ended December 31, 2009 are not necessarily indicative of
results that may be expected for future quarters or for the full fiscal year ending March 31, 2010.

(dollars in thousands, except per share amounts)



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 December 31,
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.

(dollars in thousands, except per share amounts)



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.

In June 2009, the FASB issued a standard that establishes only two levels of U.S. GAAP, 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 $14,784 related to these actions, of which $4,455 was recorded as restructuring expenses and $10,329
was recorded in cost of revenues, with expenses of $12,061 and $2,723 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 nine month periods ended December 31, 2009.

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 third quarter and first nine months of fiscal 2010 and fiscal 2009:

3. Comprehensive Income

Comprehensive income includes net income as currently reported under U.S. GAAP and other comprehensive income. Other comprehensive income
considers the effects of additional economic events that are not required to be recorded in determining net income, but rather are reported as a separate component of shareholders equity. The following table illustrates the components of our
comprehensive income:

The reduction in the unrecognized postretirement benefit plan obligation, net of taxes recorded in the three
and nine month periods ended December 31, 2008 is a result of amending and restating our United States postretirement welfare benefits plan during the third quarter of fiscal 2009. Additional information regarding the amendment and restatement
of our United States postretirement welfare 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.

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 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 December 31, 2009 and 2008 were 27.6% and 33.5%, respectively. For the nine month periods ended December 31, 2009 and 2008, the effective income tax
rates from continuing operations were 31.4% and 31.9%, respectively. The lower effective income tax rate for the three month period ended December 31, 2009 resulted principally from discrete item adjustments and tax planning initiatives.

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 December 31, 2009, we had $10,029 in
unrecognized tax

benefits, of which $1,516 would impact the effective tax rate if recognized. The decrease in unrecognized tax benefits for the three and the nine month periods ended December 31, 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 December 31, 2009. As of
December 31, 2009, we have recognized a liability for interest of $1,092 and penalties of $141.

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 current and retired 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.

Components of the net periodic benefit cost of
our defined benefit pension plans and other postretirement medical benefit plan were as follows:

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 from the ordinary course of our business, given our size, history, complexity, and the nature of our business, products, 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.

We believe we have adequately reserved for our current litigation and claims that are probable and estimable, and further believe that the ultimate outcome of these 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 or effect of current or future litigation, investigations (including without
limitation the FDA-related matters discussed below), or other claims or proceedings. For certain types of claims, 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.

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 (sometimes referred to collectively in the FDA letter and in this note 10 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.

We thereafter
met with the FDA and, on January 20, 2009, we announced that we submitted to the FDA a new liquid chemical sterilant system for 510(k) clearance. The new submission followed discussions with the FDA regarding the prior 510(k) submission issues
raised in the warning letter related to our existing device. We believe the new liquid chemical sterilant system submitted to the FDA addresses the changes referenced by the FDA in the warning letter and includes additional technology updates.
However, we have no assurance the FDA will clear the new system for sale or that the system will receive market acceptance. Also in the January 20, 2009 announcement, based on discussion with the FDA, we communicated to Customers that we would
continue supporting the existing STERIS SYSTEM 1 installed base for at least a two year period by providing accessories, sterilant, service and parts, and replacement processor units.

On December 3, 2009, the FDA provided a notice (notice) to healthcare facility administrators and infection control
practitioners describing FDAs concerns about the STERIS SYSTEM 1 Processor, components and accessories, and FDA recommendations. In that notice, FDA stated its belief that the STERIS SYSTEM 1

device had been significantly modified, that FDA had not cleared or approved the modified device, and that FDA has not determined whether the STERIS SYSTEM 1 is safe or effective for its labeled
claims. The notice further stated that use of a device that does not properly sterilize or disinfect a medical or surgical device poses risks to patients and users, including the transmission of pathogens, exposure to hazardous chemicals and affect
on the quality and functionality of reprocessed instruments. The notice stated that FDA was aware of reports of malfunctions of the STERIS SYSTEM 1 that had the potential to cause or contribute to serious injuries to patients, such as infections, or
injuries to healthcare staff, such as burns. Included in FDAs December 3, 2009 notice was a recommendation from FDA that if users had acceptable alternatives to meet sterilization and disinfection needs, users should transition to that
alternative as soon as possible. On December 10, 2009, the FDA stated its belief that Customers should be able to transition from STERIS SYSTEM 1® within three to six months.

Since the
December 3, 2009 notice, the FDA has engaged in discussions with healthcare providers, professional organizations, STERIS and others regarding this notice, its impact on users, the process of transition, acceptable alternatives, considerations
for healthcare providers concerning continued use of and transition from STERIS SYSTEM 1, and the timing of such transition. On February 2, 2010, the FDA updated its December 10, 2009 information by extending to 18 months the total
recommended time period for transitioning from SYSTEM 1 to acceptable alternative devices. We have continued to provide accessories, sterilant, service, and parts for STERIS SYSTEM 1 pursuant to FDAs enforcement discretion. At this time, we
are also continuing discussions with FDA regarding possible resolution of this matter. On February 5, 2010, a complaint was filed by a Customer who claims to have purchased two STERIS SYSTEM 1 devices from STERIS. Physicians of Winter Haven
LLC d/b/a Day Surgery Center v. Steris Corp.,Case No. 1:1-cv-00264-CAB (N.D. Ohio). The complaint alleges statutory violations, breaches of various warranties, negligence, failure to warn, and unjust enrichment. Plaintiff seeks class
certification, damages, and other legal and equitable relief including, without limitation, attorneys fees and an order requiring STERIS to replace, recall or adequately repair the product and/or to take appropriate regulatory action. We are
evaluating this matter and expect to defend against these allegations.

There is no assurance that discussions with FDA will
continue, that a resolution will be reached, that enforcement discretion will continue, that other lawsuits will not be brought, that the FDA or third party claimants will not pursue judicial, administrative or other legal or enforcement action or
seek other remedies, including a recall or an immediate demand that STERIS stop further sales of the SYSTEM 1 device and any related accessories, services and sterilant, product replacement, or damages, or that FDA or third party claimants will not
take other action as described in this note and/or in the Item entitled Risk Factors contained in this Form 10-Q or 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.

We continue to believe that the changes described in
the warning letter and the notice 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 also
described in the warning letter 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 STERISTM20 sterilant, a significant product to us, could possibly result in
judgments, settlements or administrative or judicial decrees 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, Customer or
other third party claims or remedies, which could materially affect our business, performance, prospects, value, financial condition, and results of operations. Most of the STERIS SYSTEM 1 sales are within the United States. It is unclear what
impact the FDAs action, litigation, or other events described may have on sales of the device outside the United States. We intend to continue our discussions with the FDA to seek resolution of all issues described in the warning letter, the
December 3rdnotice and any related proceedings or
investigation.

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 sterilant 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 sterilant system consistent with the purchase and use of existing STERIS SYSTEM 1®, and see Item 1A. of Part II.

From time to time, we are 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 (E-Beam), and Ethylene Oxide (EO) technologies. We provide sterilization and microbial reduction to companies that supply products to the healthcare, industrial, and consumer products industries. During the third
quarter of fiscal 2010, a decision was made to close the Nogales, Arizona facility and exit the E-Beam materials modification business. These actions will occur over the next several months.

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 nine month periods ended December 31, 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.

Financial information for each of our segments is presented in the following tables:

12. Common Shares

Basic earnings per common share are calculated based upon the weighted average number of common shares outstanding. Restricted share awards that participate in dividends are included in the determination
of basic earnings per common share. Diluted earnings per common share are calculated based upon the weighted average number of common shares outstanding plus the dilutive effect of options calculated using the treasury stock method. The following
table summarizes common shares and options 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 11,220 of our common shares during the first nine 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 December 31, 2009, $203,864 of STERIS common shares remained authorized for repurchase and 10,914,377 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
the form of 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. Restricted shares and restricted share units generally cliff vest over an approximately three-year period. As of December 31, 2009, 3,751,936 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 nine months 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. 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 nine months of fiscal 2010 is as follows:



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

The aggregate
intrinsic value in the table above represents the total pre-tax difference between the $27.97 closing price of our common shares on December 31, 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 nine months of fiscal 2010 and fiscal 2009 were $5,350 and $24,348,
respectively. Net cash proceeds from the exercise of stock options were $12,339

and $8.74 for the first nine months of fiscal 2010 and fiscal 2009, respectively.

Stock appreciation rights
(SARS) were also granted during the first nine months 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 outstanding SARS are revalued at each reporting date and the related expense is adjusted appropriately.

Restricted share
and restricted share unit activity for the first nine months 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 nine months of fiscal 2010 and fiscal 2009 was $2,093 and $1,281, 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 nine months of fiscal 2010 and fiscal
2009, respectively.

As of December 31, 2009, there was $9,243 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 1.68 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 countries 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 nine months of fiscal 2010 were as

|                                    |  |   |        |  

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 $17,819 and $17,477 as of December 31, 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 December 31, 2009:



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

the same notional amounts and maturity dates.

|(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 December 31, 2009 through February 9, 2010, 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.

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 December 31,
2009, and the related consolidated statements of income for the three-month and nine-month periods ended December 31, 2009 and 2008, and the consolidated statements of cash flows for the nine-month periods ended December 31, 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 28, 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, including note 10 in the consolidated
financial statements contained herein regarding the matter with the FDA, which present the results of our operations for the third quarter and the first nine months 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 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 dividends, and

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 third quarter revenues were $327.8 million representing a 2.6% increase driven primarily by increases in the
Healthcare and Life Sciences reportable business segments. Revenues for the first nine months of fiscal 2010 were $925.6 million, representing a decrease of 3.0% year-over-year, driven primarily by a decline in our Healthcare business segment. Our
gross margin percentages were 42.5% and 42.9% for the third quarter and first nine months of fiscal 2010, which was an increase of 370 basis points compared to the same prior year quarter and an increase of 230 basis points from the first nine
months of fiscal 2009. Gross margins during both fiscal 2009 periods include pre-tax expenses of $9.5 million related to our restructuring actions, which are discussed in further detail below and in note 2 to the consolidated financial statements.
Gross margins during both fiscal 2010 periods benefited from price increases and lower raw material costs. On a year-to-date basis, gross margins also benefited from favorable foreign currency fluctuations.

Revenues, in the United States, for STERIS SYSTEM 1®, including capital equipment, sterilant and accessories, parts and service, are approximately 10.0% of total company revenues for the first nine months of both fiscal
2010 and fiscal 2009.

Free cash flow was $129.4 million in the first nine months of fiscal 2010 compared to $89.6 million in
the prior year first nine months, 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 29.7% at December 31, 2009 as compared to 22.6% at
March 31, 2009, reflecting an additional borrowing of $100.0 million in the third quarter, and increased operating income. We also declared and paid cash dividends totaling $2.33 per common share in the first nine months of fiscal 2010
including a special dividend of $2.00 per common share. In the first nine months of fiscal 2009, we declared and paid cash dividends totaling $0.22 per common share.

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

Matters Affecting Comparability

Restructuring. During the third quarter and first nine months 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 third quarter of fiscal 2010, our revenues were favorably impacted by $4.8 million, or 1.5%, and income before taxes was unfavorably impacted by $5.3 million, or 9.3%, as a result of foreign
currency movements relative to the U.S. dollar. During the first nine months of fiscal 2010, our revenues were unfavorably impacted by $5.3 million, or 0.6%, and income before taxes was unfavorably impacted by $0.1 million as compared to the same
prior year period.

Results of Operations

In the following subsections, we discuss our earnings and the factors affecting them for the third quarter and first nine months of fiscal 2010 compared with the same fiscal 2009 periods. We begin with a

Quarter over Quarter Comparison

Revenues increased $8.4 million, or 2.6%, to $327.8 million for the quarter ended December 31, as compared to $319.5 million for the
comparable prior year quarter. Capital equipment revenues increased $3.0 million, or 2.3% as a result of increased sales in Canada, Europe, Asia Pacific and the Latin America region offset by a decrease in the United States. Recurring revenues
increased 2.9%, with an increase of 10.6% in consumable revenues, and a decrease in service revenues of 2.1%. Consumables growth in the United States and Europe was partially offset by declines in service revenues in the United States.

International revenues increased $14.7 million, or 21.2%, to $83.8 million, for the quarter ended December 31, 2009, as compared to
$69.1 million for the comparable prior year quarter. International revenues were favorably affected by increases in capital equipment revenues, which increased 32.2% due to increases within both our Healthcare and Life Science segments.
International recurring revenues increased during the third quarter of fiscal 2010 by 9.0%, with increases of 15.5% and 3.1% in consumable and service revenues, respectively.

United States revenues decreased $6.3 million, or 2.5%, to $244.1 million, for the quarter ended December 31, 2009, as compared to
$250.4 million for the comparable prior year quarter. The decrease in United States revenues reflects a 9.4% decrease in capital equipment revenues. United States recurring revenues increased 1.6% with a 9.3% increase in consumable revenues
partially offset by a decrease of 3.0% in service revenues.

First Nine Months over First Nine Months Comparison

Revenues decreased $28.6 million, or 3.0%, to $925.6 million for the first nine months of fiscal 2010, as compared
to $954.2 million during the first nine months of fiscal 2009. Capital equipment revenues decreased 9.4%, primarily driven by weaker demand within the Healthcare business segment in the United States. Recurring revenues increased 1.2% reflecting an
increase in consumable revenues of 8.8% offset by a decline of 3.6% in service revenues.

International revenues for the first
nine months of fiscal 2010 were $219.4 million, an increase of $2.0 million, or 0.9%, as compared to the first nine months of fiscal 2009. Fiscal 2010 year-to-date international revenues were favorably impacted by a 2.5% increase in capital
equipment revenues which was offset by a decline of 0.9% in recurring revenues, reflecting a decline in service revenues that more than offset a rise in consumable revenues.

United States revenues for the first nine months of fiscal 2010 were $706.2 million, a decrease of $30.5 million, or 4.1%, as compared to
the first nine months of fiscal 2009. The fiscal 2010 year-to-date decrease in United States revenues was primarily driven by a 16.4% decrease in capital equipment revenues in our Healthcare segment. United States recurring revenues grew 1.7% as an
11.0% growth in consumable revenues was partially offset by a 3.6% decline in service revenues. The service revenues decline included a reduction in revenues resulting from the sale, in fiscal 2009 of two Isomedix facilities.

Revenues are further discussed on a segment basis in the section of MD&A titled, Business Segment Results of

and services, as well as the costs associated with the products and services that are sold. Gross margin for the third quarter of fiscal 2010 amounted to 42.5%, representing an increase of 370 basis points as compared to the same prior year period.
For the first nine months of fiscal 2010, gross margin amounted to 42.9%, representing an increase of 230 basis points as compared to the same prior year period. Gross margins during both the third quarter and first nine months of fiscal 2009
included pre-tax expenses of $9.5 million related to our restructuring actions. Gross margins during both fiscal 2010 periods benefited from price increases and lower raw material costs. On a year-to-date basis, gross margins also benefited from
favorable foreign currency fluctuations.

Operating Expenses.The following table compares our
operating expenses for the three and nine month periods ended December 31, 2009 to the three and nine month periods ended December 31, 2008:

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 increased 80 basis points to 21.9% for the third
quarter of fiscal 2010 and decreased 40 basis points to 23.9% for the first nine months of fiscal 2010, as compared to the same prior year periods. Both fiscal 2009 periods include a reduction of $7.9 million resulting from a prior year change in
our paid time off benefits. Also included in the first nine months of fiscal 2009 is a $2.1 million gain on the sale of an Isomedix facility located in the Chicago, Illinois area to a Customer. Both fiscal 2010 periods reflect improved operating
expense leverage and the benefit of efficiency initiatives previously implemented.

As a percentage of total revenues,
research and development expenses were 2.5% and 2.6% for the three and nine month periods ended December 31, 2009, as compared to 2.5% and 2.6%, respectively, for the same prior year periods. For the three month period ended December 31,
2009, research and development expenses increased 1.8% to $8.3 million as compared to $8.1 million during the same prior year period. For the first nine months of fiscal 2010, research and development expenses decreased 1.8% to $24.0 million, as
compared to $24.5 million, during the same prior year period. The fiscal 2010 period includes a government subsidy of $0.8 million received for research and development expenses incurred by one of our international locations. 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 third quarter and first nine months 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 third quarter and first nine months of fiscal 2010 and fiscal 2009 are summarized in the following tables:

month periods ended December 31, 2009 were 27.6% and 31.4%, respectively, as compared to 33.5% and 31.9%, respectively, for the same prior year periods. The lower effective income tax rate
for the third quarter of fiscal 2010 resulted principally from discrete item adjustments and tax planning initiatives.

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 effective income tax rate,
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.

Business Segment Results of Operations.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 Annual Report on Form 10-K for the year ended March 31, 2009, filed with the SEC on May 29, 2009, provides additional information about each business segment. The following table compares business segment
revenues for the three and nine month periods ended December 31, 2009 to the three and nine month periods ended December 31, 2008:

Healthcare Segment

Healthcare segment revenues represented 71.2% of total revenues for the third quarter of fiscal 2010 compared with 72.1% for the same prior
year period. Healthcare revenues increased $3.1 million, or 1.3%, to $233.3 million for the quarter ended December 31, 2009, compared with $230.2 million for the third quarter of the prior year. Consumable revenues increased 10.4% for the
quarter ended December 31, 2009 because of increased demand for our products. This increase was partially offset by declines in revenues from capital equipment and service of 2.2% and 1.3%, respectively. At December 31, 2009, the
Healthcare segments backlog amounted to $134.4 million, increasing $4.5 million, or 3.4%, compared to the backlog of $129.9 million at September 30, 2009 and increasing $0.5 million, or 0.4%, compared to the backlog of $133.9 million at

##### Table of Contents

Healthcare segment revenues represented 71.0% of total revenues for the first nine months of
fiscal 2010 compared with 71.5% for the same prior year period. Healthcare revenues decreased $25.2 million, or 3.7%, to $656.9 million for the nine months ended December 31, 2009, as compared to $682.1 million for the same prior year period.
The decrease is attributed to lower capital equipment and service revenues, which decreased 10.5% and 3.4%, respectively, primarily due to declines within the United States. Consumable revenues grew 7.9%, primarily within the United States and
Europe.

Life Sciences Segment

Life Sciences segment revenues represented 18.0% of total revenues for the third quarter of fiscal 2010 compared with 16.5% for the same prior year period. Life Sciences revenues increased $6.1 million,
or 11.6%, to $58.9 million for the quarter ended December 31, 2009, as compared to $52.8 million for the third quarter of the prior year. Capital revenues grew 26.6% with increases in Canada, Europe and Latin America. Interim capital revenues
within the Life Sciences segment can be impacted by various factors including the status of customer projects and production lead times. Consumables revenues increased 11.2%. These increases were slightly offset by a decrease in service revenues of
4.2%. At December 31, 2009, the Life Sciences segments backlog amounted to $45.4 million, a decrease of $1.1 million, or 2.4%, compared to the backlog of $46.5 million at September 30, 2009 and a decrease of $4.8 million, or 9.6%,
compared to the backlog of $50.2 million at December 31, 2008.

Life Sciences segment revenues represented 17.2% of total
revenues for the first nine months of fiscal 2010, compared with 16.6% for the same prior year period. Life Sciences revenues increased $1.5 million, or 0.9%, to $159.4 million for the first nine months of fiscal 2010, as compared to $158.0 million
for the same prior year period. The increase in Life Sciences revenues was primarily driven by a 13.2% increase in consumable revenues reflecting increases in United States and Europe. The increase was offset by decreases in both capital equipment
and service revenues of 3.3% and 3.1%, respectively. Capital equipment revenues continue to be impacted by project delays, by our pharmaceutical and research Customers.

Isomedix Segment

Isomedix segment revenues represented 10.7%
of total revenues for the third quarter of fiscal 2010, compared with 10.8% for the comparable prior year quarter. The segments revenues increased $0.3 million, or 1.0% to $35.0 million during the third quarter of fiscal 2010, as compared to
$34.6 million during the comparable prior year quarter.

Isomedix segment revenues represented 11.4% of total revenues for the
first nine months of fiscal 2010 compared with 11.4% for the comparable prior year period. The segment experienced decreased revenues of $3.3 million, or 3.1%, to $105.1 million during the first nine months of fiscal 2010 as compared to $108.5
million for the same prior year period. Revenues were affected by the previously disclosed sale of two facilities during fiscal 2009, which were partially offset by a modest improvement in demand from medical device customers.

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 $12.8 million and $19.4 million for the third quarter and
first nine months of fiscal 2010, respectively, as compared to the same prior year periods. The segments operating margins were 19.4% and 17.3% for the third quarter and first nine months of fiscal 2010, respectively, representing increases of
530 basis points and 350 basis points, respectively, as compared to prior year periods. The Healthcare segments operating income for the third quarter and first nine months of fiscal 2009 include $10.0 million and $9.8 million in pre-tax
expenses, respectively, related to our restructuring actions. Both fiscal 2009 periods also include a pre-tax benefit of $5.9 million resulting from the change in our benefit policy related to paid time off. The improvement in operating income was
driven by operating efficiencies and lower raw material costs.

Life Sciences Segment

The Life Sciences segments operating income increased $3.0 million and $9.0 million for the third quarter and first nine months of
fiscal 2010, respectively, as compared to the same prior year periods. The segments operating margins were 17.2% and 14.7% for the third quarter and first nine months of fiscal 2010, respectively, representing increases of 370 basis points and
560 basis points, respectively, over the comparable prior year periods. The Life Sciences segments operating income for both fiscal 2009 periods includes pre-tax expenses of $2.4 million related to our restructuring actions. Both fiscal 2009
periods also include a pre-tax benefit of $1.2 million resulting from the change in our benefit policy related to paid time off. The improvement in year over year operating income was primarily driven by operating efficiencies.

Isomedix Segment

The Isomedix segments operating income decreased $1.5 million and $4.2 million for the third quarter and first nine months of fiscal 2010, respectively, as compared to the same prior year periods. The segments operating margins

both fiscal 2009 periods, the Isomedix segments operating margins include a pre-tax benefit of $0.8 million resulting from the change in our benefit policy related to paid time off.
Included in the segments operating income for the first nine months of fiscal 2009 is a $2.1 million pre-tax gain on the sale of a facility located in the Chicago, Illinois area to a Customer. During the third quarter of fiscal 2010, decisions
were made to close the Nogales, Arizona facility and exit the E-Beam materials modification business resulting in pre-tax expense of $1.7 million. Annualized revenues will be reduced by approximately $1.0 million as a result of these decisions.

Net Cash Provided by Operating Activities. The net cash provided by our
operating activities was $158.7 million for the first nine months of fiscal 2010 compared with $108.3 million for the first nine 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, deferred income taxes,
share-based compensation expense, loss (gain) on disposal of property, plant, equipment and intangibles and other items. Non-cash items were $54.3 million for the first nine months of fiscal 2010 compared with $50.6 million for the first nine months
of fiscal 2009. Significant changes in these items for the first nine months 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 $42.0 million and $43.9 million for the first nine months of fiscal 2010 and 2009, respectively.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Deferred income taxes  Our deferred income tax benefits decreased $1.2 million for the first nine months of fiscal 2010, compared with an
increase of $10.9 million for the first nine months of fiscal 2009 due to the timing and recognition of settlements and changes in provisions.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Loss (gain) on the disposal of property, plant, equipment, and intangibles  During the first nine months of fiscal 2010, we recorded a loss of
$1.5 million for the disposal of property, plant, equipment, and intangibles, compared with a gain of $1.4 million for the same prior year period. Included in the loss recorded during the first nine months of fiscal 2010 is the cost associated with
the decision to exit the E-beam materials modification business, which represented a small portion of Isomedix revenues. Included in the gain during the first nine months of fiscal 2009 is the $2.1 pre-tax gain on the sale of an Isomedix facility in
the Chicago, Illinois area to a Customer, partially offset by asset impairments related to the Fiscal 2009 Restructuring Plan.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other items  Other items amounted to $4.0 million for the first nine months of fiscal 2010 as compared to a negative $8.3 million for the first
nine months of fiscal 2009. The year over year change primarily reflects a $7.9 million non-cash adjustment as a result of a change in our benefit policy with respect to paid time off and an estimated curtailment gain related to our Switzerland
defined benefit pension plan included in the fiscal 2009 period.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Changes in operating assets and
liabilities  Changes to our operating assets and liabilities amounted to a positive $5.7 million and a negative $25.2 million during the first nine months of fiscal 2010 and fiscal 2009, respectively. Significant changes in the first nine
months of fiscal 2010 as compared to the first nine months of fiscal 2009 are summarized below:



| |  |  | Accounts receivable, net  Changes in our net accounts receivable balances provided cash of $38.1 million and $25.7 million during the first nine
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 $9.3 million for the first nine months of fiscal 2010 whereas
increases in our net inventory balance drove uses of cash of $12.8 million during the first nine months of fiscal 2009. Inventory balances in fiscal 2010 reflect reductions in inventory levels and lower raw material costs.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 $3.4 million and $10.7 million for the first nine months of fiscal 2010 and 2009, respectively.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts payable, net  Decreases in our net accounts payable balances drove uses of cash of $14.8 million and $13.3 million during the first nine
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 $30.1 million and $35.5 million during
the first nine months of fiscal 2010 and fiscal 2009, respectively. The higher cash usage in the first nine months 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.

improved cash flow from operating assets and liabilities. Our debt-to-total capital ratio was 29.7% at December 31, 2009 and 22.6% at March 31, 2009. Our net debt-to-total capital ratio
was 5.7% at December 31, 2009 and 7.2% 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 $30.9 million at December 31, 2009 reflecting a net decrease of $1.6 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 December 31, 2009, the maximum amount available for
borrowing under this Facility was $275.6 million. The maximum aggregate borrowing limit of $400.0 million under the Facility is reduced by outstanding borrowings ($100.0 million at December 31, 2009) and letters of credit issued under a
sub-limit within the Facility ($24.4 million at December 31, 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 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 third quarter of fiscal 2010, our revenues were favorably impacted by $4.8 million, or 1.5%, and income before taxes
was unfavorably impacted by $5.3 million, or 9.3%, as a result of foreign currency movements relative to the U.S. dollar. During the first nine months of fiscal 2010, our revenues were unfavorably impacted by $5.3 million, or 0.6%, and income before
taxes was unfavorably impacted by $0.1 million as compared to the same prior year period.

interpretation thereof. Other risk factors are described herein and in the Companys Form 10-K and other securities filings. Many of these important factors are outside STERISs control. No assurances can be provided as to any outcome from
litigation, regulatory action, administrative proceedings, government investigations, warning letters, cost reductions, business strategies, rebate programs, earnings and revenue trends, expense reduction or other future financial results. Unless
legally required, the Company does not undertake to update or revise any forward-looking statements even if events make clear that any projected results, express or implied, will not be realized. Other potential risks and uncertainties that could
cause actual results to differ materially from those in the forward-looking statements include, without limitation, (a) the potential for increased pressure on pricing that leads to erosion of profit margins, (b) the possibility that
product approvals will not occur or market demand will not develop for new technologies, products or applications (including the new liquid chemical sterilant technology), or the Companys business initiatives will take longer, cost more or
produce lower benefits than anticipated, (c) the possibility that claims, litigation, certifications, or other demands, requirements or standards, or the application of or compliance with laws, court rulings, regulations, regulatory actions,
including without limitation previously disclosed FDA warning letters, government investigations, and the December 3, 2009 FDA notice, may delay or prevent new product introductions, affect the production and marketing of existing products or
otherwise affect Company performance, results, prospects or value, or may require the Company to take other actions, including recalls, to pay significant monetary fines or civil damages, or to be subject to other governmental or third party claims
or remedies, which could materially affect our performance, results, prospects or value (d) the potential of international unrest or effects of fluctuations in currencies, tax assessments or rates, raw material costs, benefit or retirement plan
costs, or other regulatory compliance costs, (e) the possibility of reduced demand, or reductions in the rate of growth in demand, for the Companys products and services, (f) the possibility that anticipated revenue, profitability,
cost savings, efficiencies, or other results may not be achieved or may be delayed, or that transition, labor, competition, timing, execution, regulatory, governmental, or other issues or risks associated with the matters described in this report
may adversely impact our performance, results, prospects or value, (g) the effect of the contraction in credit availability, 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 and this Form 10-Q for the quarter ended December 31, 2009.

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, products, 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.

We believe we have adequately reserved for our current litigation and claims that are probable and estimable, and further believe that the ultimate outcome of these 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 or effect of current or future litigation,
investigations (including without limitation the FDA-related matters discussed below), claims or other proceedings. For certain types of claims, 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.

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 (sometimes referred to collectively in the FDA letter and in this Item 1 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

##### Table of Contents

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.

We thereafter met with the FDA and, on January 20, 2009, we announced that we submitted to the FDA a new liquid chemical sterilant system for 510(k) clearance. The new submission followed discussions with the FDA regarding the prior
510(k) submission issues raised in the warning letter related to our existing device. We believe the new liquid chemical sterilant system submitted to the FDA addresses the changes referenced by the FDA in the warning letter and includes additional
technology updates. We have no assurance the FDA will clear the new system for sale or that the system will receive market acceptance. Also in the January 20, 2009 announcement, based on discussion with the FDA, we communicated to Customers
that we would 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.

On
December 3, 2009, the FDA provided a notice (notice) to healthcare facility administrators and infection control practitioners describing FDAs concerns about the STERIS SYSTEM 1 Processor, components and accessories, and
FDA recommendations. In that notice, FDA stated its belief that the STERIS SYSTEM 1 device had been significantly modified, that FDA had not cleared or approved the modified device, and that FDA has not determined whether the STERIS SYSTEM
1® is safe or effective for its labeled claims. The notice further stated that use of a device that does not
properly sterilize or disinfect a medical or surgical device poses risks to patients and users, including the transmission of pathogens, exposure to hazardous chemicals and affect on the quality and functionality of reprocessed instruments. The
notice stated that FDA was aware of reports of malfunctions of the STERIS SYSTEM 1® that had the potential to
cause or contribute to serious injuries to patients, such as infections, or injuries to healthcare staff, such as burns. Included in FDAs December 3, 2009 notice was a recommendation from FDA that if users had acceptable alternatives to
meet sterilization and disinfection needs, users should transition to that alternative as soon as possible. On December 10, 2009, the FDA stated its belief that Customers should be able to transition from STERIS SYSTEM 1 within three to six
months.

Since the December 3, 2009 notice, the FDA has engaged in discussions with healthcare providers, professional
organizations, STERIS and others regarding this notice, its impact on users, the process of transition, acceptable alternatives, considerations for healthcare providers concerning continued use of and transition from STERIS SYSTEM 1, and the timing
of such transition. On February 2, 2010, the FDA updated its December 10, 2009 information by extending to 18 months the total recommended time period for transitioning from SYSTEM 1 to acceptable alternative devices. We have continued to
provide accessories, sterilant, service, and parts for STERIS SYSTEM 1 pursuant to FDAs enforcement discretion. At this time, we also are continuing discussions with FDA regarding possible resolution of this matter. On February 5, 2010, a
complaint was filed by a Customer who claims to have purchased two STERIS SYSTEM 1 devices from STERIS. Physicians of Winter Haven LLC d/b/a Day Surgery Center v. Steris Corp.,Case No. 1:1-cv-00264-CAB (N.D. Ohio). The complaint alleges
statutory violations, breaches of various warranties, negligence, failure to warn, and unjust enrichment. Plaintiff seeks class certification, damages, and other legal and equitable relief including, without limitation, attorneys fees and an
order requiring STERIS to replace, recall or adequately repair the product and/or to take appropriate regulatory action. We are evaluating this matter and expect to defend against these allegations.

There is no assurance that discussions with FDA will continue, that a resolution will be reached, that enforcement discretion will continue,
that other lawsuits will not be brought, that the FDA or third party claimants will not pursue judicial, administrative or other legal or enforcement action or seek other remedies, including a recall or an immediate demand that we stop further sales
of the SYSTEM 1 device and any related accessories, services and sterilant, product replacement, or damages, or take other action as described in this

##### Table of Contents

Item, in the Item entitled Risk Factors contained in this Form 10-Q or 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.

We continue to believe that the changes described in
the warning letter and the notice 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 also
described in the warning letter 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 STERISTM20 sterilant, a significant product to us, could possibly result in
judgments, settlements or administrative or judicial decrees 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, Customer or other third party claims or remedies, which could materially affect our business, performance, prospects, value, financial condition, and results of operations. Most of the STERIS SYSTEM 1 sales
are within the United States. It is unclear what impact the FDAs action, litigation, or other events described may have on sales of the device outside the United Sates. We intend to continue our discussions with the FDA to seek resolution of
all issues described in the warning letter, the December 3rdnotice and any related proceedings or investigation.

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 sterilant 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 sterilant system consistent with the purchase and use of existing STERIS SYSTEM 1®, and see Item 1A. below.

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.

Except as noted above, we believe there have been no material recent developments concerning our legal proceedings since September 30,
2009 and no new material pending legal proceedings that are required to be reported.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

The
following supplements the risk factors that were included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2009, filed with the SEC on May 29, 2009:

Our business may be adversely affected as a result of the December 3, 2009 U.S. Food and Drug Administration notice to healthcare administrators.



47



---

##### Table of Contents

FDAs December 3, 2009 notice advises healthcare administrators that the FDA
believes we have significantly modified STERIS SYSTEM 1, and therefore, were required to submit a new premarket notification to the FDA. As a result, the agency stated that it has not determined that STERIS SYSTEM 1 is safe or effective for
sterilizing medical devices. The FDA recommends in the notice that Customers transition to an acceptable alternative as soon as possible if they have one; if not, that they promptly assess their patient care needs and sterilization and disinfection
requirements and take steps to obtain legally-marketed STERIS SYSTEM 1 substitutes. As a result of this notice, some Customers may quickly transition away from or terminate the use of STERIS SYSTEM 1, reduce or discontinue the purchase of sterilant
and services relating to STERIS SYSTEM 1, reduce or discontinue purchases of other STERIS products, including other STERIS products that the FDA considers acceptable alternatives, or take other action that could materially adversely affect our
business. These Customers also may be disinclined to purchase our new liquid chemical sterilant system, now pending before the FDA, and there is no assurance that the FDA will clear the device. We may offer incentives and/or other consideration to
Customers in conjunction with this situation. Revenues lost, transition costs incurred, incentives or other consideration provided, claims and compliance costs, and other expenses incurred and impact resulting from these circumstances, may have an
material adverse effect on our business, performance, prospects, value, financial condition and results of operations.



|ITEM 2. | UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
|------- | -----------------------------------------------------------

During the third quarter of fiscal 2010, we did not repurchase any of our common shares under our repurchase program. A repurchase program was approved by the Companys Board of Directors and
announced on March 14, 2008, which authorized the repurchase of up to $300.0 million of our common shares. As of December 31, 2009, $203.9 million in common shares remained available for repurchase under this authorization. This common
share repurchase authorization does not have a stated maturity date. The following table summarizes the common shares repurchased during the third quarter of fiscal 2010 under our common share repurchase program:
