STERIS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

For the Three and Six
Months Ended

September 30, 2007 and 2006

(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 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 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 present fairly the 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, 2007, filed with the Securities and Exchange Commission (SEC) on May 30, 2007. The Consolidated Balance Sheet at March 31, 2007 has been derived from the audited
consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. 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. 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 six-month periods ended September 30, 2007 are not necessarily indicative of results that may be expected for future quarters or for the full fiscal year
ending March 31, 2008.

(dollars in thousands, except per share amounts)



Recently Adopted Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48 (FIN No. 48),
Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109. This interpretation clarifies the recognition threshold and measurement attribute for financial statement recognition and measurement of
tax positions taken or expected to be taken on a tax return. Under FIN No. 48, the economic benefit associated with a tax position is only recognized if it is more likely than not that the tax position will be sustained. After this threshold is
met, a tax position is reported at the largest amount of benefit that is more likely than not to be ultimately sustained. FIN No. 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods,
disclosure and transition. FIN No. 48 requires the cumulative effect of adoption to be recorded as an adjustment to the opening balance of retained earnings. We adopted FIN No. 48 effective April 1, 2007, as required. Prior to
April 1, 2007, we regularly assessed our positions with respect to tax exposures and recorded liabilities for uncertain income tax positions according to Statement of Financial Accounting Standards No. 5 (SFAS No. 5),
Accounting for Contingencies. We describe the impact of adopting FIN No. 48 further in note 8 to our consolidated financial statements titled, Income Tax Expense.

New Accounting Pronouncements

In February
2007, the FASB issued Statement of Financial Accounting Standards No. 159 (SFAS No. 159), The Fair Value Option for Financial Assets and Financial LiabilitiesIncluding an Amendment of SFAS 115, which permits
entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and losses arising after adoption are reported in earnings. SFAS
No. 159 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact of adopting SFAS No. 159 on our consolidated financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (SFAS No. 157), Fair Value
Measurements. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require new
fair value measurements, rather it applies under existing accounting pronouncements that require or permit fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating
the impact of adopting SFAS No. 157 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, 2007, filed with the SEC on May 30, 2007. Our significant and critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2007, other than the adoption of FIN
No. 48 as described above.

2. Restructuring

We recognize restructuring expenses as incurred as required under the provisions of Statement of Financial Accounting Standards No. 146 (SFAS No. 146), Accounting for Costs Associated with
Exit or Disposal Activities. In addition, we assess the property, plant and equipment associated with the related facilities for

impairment under Statement of Financial Accounting Standards No. 144 (SFAS No. 144), Accounting for the Impairment or Disposal of
Long-Lived Assets. Asset impairment and accelerated depreciation expenses primarily relate to an adjustment in the carrying value of the related facilities to their estimated fair value. In addition, the remaining useful lives of other
property, plant and equipment associated with the related operations were re-evaluated based on the respective restructuring plan, resulting in the acceleration of depreciation and amortization of certain assets.

Fiscal 2006 Restructuring Plan

During the three and
six months ended September 30, 2007, we recorded $733 and $2,123, respectively, in restructuring expenses primarily related to the previously announced transfer of the Erie, Pennsylvania manufacturing operations to Monterrey, Mexico (the
Fiscal 2006 Restructuring Plan), which is intended to improve our cost structure. During the three and six months ended September 30, 2006 we recorded $1,158 and $2,263, respectively, in restructuring expenses related to the
transfer of manufacturing operations. Additional information regarding the Fiscal 2006 Restructuring Plan is included in our Annual Report on Form 10-K for the year ended March 31, 2007, filed with the SEC on May 30, 2007.

The costs incurred during the second quarter and first half of fiscal 2008 and fiscal 2007 are associated with the Healthcare business segment. Since the
inception of the Fiscal 2006 Restructuring Plan, we have incurred restructuring expenses of $32,299, with restructuring expenses of $31,885 and $414 related to the Healthcare and Life Sciences segments, respectively, primarily related to the
transfer of manufacturing operations to Monterrey, Mexico.

We anticipate incurring approximately an additional $2,800 during fiscal 2008
in connection with the transfer of the manufacturing operations to Mexico. Restructuring expenses to be incurred include compensation and benefits, severance, accelerated depreciation and other expenses.

The following tables summarize our total restructuring expenses for the second quarter and first half of fiscal 2008 and fiscal 2007:

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). For the three and six months ended
September 30, 2007, we did not incur any additional restructuring expenses related to the European Restructuring Plan and settled certain termination benefits for less than originally expected. Since the inception of the plan, we have incurred
restructuring expenses of $1,668, with restructuring expenses of $1,178 and $490 related to the Healthcare and Life Sciences segments, respectively, primarily related to severance and termination benefits. We continue to evaluate our European
operations for opportunities to enhance performance, but we have not committed to any additional specific restructuring actions.

Liabilities related to the European Restructuring Plan activities are recorded as current liabilities on the accompanying Consolidated Balance Sheets within Accrued expenses and other. The following table summarizes our
liabilities related to these restructuring activities:

3. Comprehensive Income

Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income, establishes standards for reporting comprehensive income. Comprehensive income includes net income as currently
reported under U.S. 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:

5. Inventories, Net

Inventories, net are stated at the lower of cost or market. We use the last-in,
first-out (LIFO) and first-in, first-out (FIFO) cost methods. An actual valuation of inventory under the LIFO method is made only at the end of the fiscal year based on the inventory levels and costs at that time.
Accordingly, interim LIFO calculations are based on managements estimates of expected year-end inventory levels and are subject to the final fiscal

On September 13, 2007, we signed the Second Amended and Restated Credit Agreement (the
Credit Agreement) with KeyBank National Association, as administrative agent for the lending institutions that are parties to the Credit Agreement (the Agent), and the other lenders that may from time to time be a party to
the Credit Agreement. This Credit Agreement amends, restates, and replaces our Amended and Restated Credit Agreement dated March 29, 2004, as amended, which was to mature in June 2010. The Credit Agreement matures on September 13, 2012 and
provides $400,000 of credit, which may be increased by up to an additional $100,000 in specified circumstances, for borrowings and letters of credit. A floating interest rate is applied to amounts borrowed as defined in the Credit Agreement or a
fixed rate may be applied based on the Eurodollar Rate or other defined currency rate, plus a margin based on our leverage ratio. Interest is payable quarterly or at the end of the interest period, if shorter. We may prepay floating rate loans
without paying a penalty, but we may be required to pay a penalty for prepaying fixed rate loans. The Credit Agreement also allows us to make short term swing loan borrowings not to exceed $35,000, with an interest rate equal to the Agents
cost of funds plus a margin. Our obligations under the Credit Agreement are unsecured but guaranteed by our material domestic subsidiaries.

Additional information regarding our indebtedness is included in our Annual Report on Form 10-K for the year ended March 31, 2007, filed with the SEC on May 30, 2007.

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 for continuing operations for the three-month
periods ended September 30, 2007 and 2006 were 37.4% and 34.5%, respectively. For the six-month periods ended September 30, 2007 and 2006, the effective income tax rates for continuing operations were 37.0% and 38.3%, respectively. The
lower effective income tax rate for the three-month period ended September 30, 2006 resulted principally from discrete item adjustments to recognize additional deferred tax assets related to foreign tax credits. The lower effective income tax
rate for the six-month period ended September 30, 2007 resulted from discrete item adjustments resulting from income tax audits in the United States and Canada.

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.

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

For
the Three and Six Months Ended

September 30, 2007 and 2006

(dollars in thousands, except per share amounts)



Effective April 1, 2007, we adopted the provisions of FIN No. 48. In accordance with FIN
No. 48, we recognized a cumulative-effect adjustment of $8,433, increasing our liability for unrecognized tax benefits, interest, and penalties and reducing the April 1, 2007 balance of retained earnings. At April 1, 2007, we had
$15,207 in unrecognized tax benefits, of which $8,702 would affect the effective tax rate if recognized.

In conjunction with the adoption
of FIN No. 48, we classified uncertain tax positions as long-term liabilities within Deferred income taxes, net in our accompanying Consolidated Balance Sheets unless expected to be paid within 12 months. We recognize accrued
interest and penalties related to unrecognized tax benefits within Income tax expense in our accompanying Consolidated Statements of Income. At April 1, 2007, we had accrued $3,449 and $2,906 for the potential payment of interest
and penalties, respectively.

There were no significant changes to any of these amounts during the second quarter or first half of fiscal
2008. It is reasonably possible that unrecognized tax benefits may decrease by up to $1,765 within 12 months of September 30, 2007 primarily as a result of the settlement of federal audits and the closure of statutes of limitation.

We operate in numerous taxing jurisdictions and are subject to regular examinations by various United States federal, state and foreign jurisdictions.
We are no longer subject to United States federal examinations for years before 1999 and, with limited exceptions, we are no longer subject to foreign, state and local tax examinations for years before 2003.

9. Benefit Plans

We provide defined benefit pension
plans for certain manufacturing and plant administrative personnel throughout the world as determined by collective bargaining agreements or employee benefit standards. In addition to providing pension benefits to certain employees, we sponsor an
unfunded postretirement medical benefit plan for two groups of United States employees comprised substantially of 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 insurance, including prescription drug coverage and Medicare supplemental coverage. Additional information regarding our defined benefit pension plans and other postretirement medical benefit plan is
included in our Annual Report on Form 10-K for the year ended March 31, 2007, filed with the SEC on May 30, 2007.

During the
fourth quarter of fiscal 2006, we recorded curtailment and special termination benefit losses associated with the restructuring plan to transfer certain manufacturing operations from Erie, Pennsylvania to Monterrey, Mexico. Fiscal 2008 and fiscal
2007 net periodic benefit costs are reduced as a result of the recognition of these losses.

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. During the first half of fiscal 2008 and fiscal 2007, we contributed $2,404 and $3,125, respectively, to our United States defined benefit pension plans. As a result of
making these contributions and due to the investment performance of the plan assets, we are not required to, and we do not anticipate making further contributions to, the United States defined benefit pension plans in fiscal 2008.

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 involved in various patent, product liability, consumer, environmental, tax proceedings and
claims, governmental investigations, and other legal and regulatory proceedings that arise from time to time in the ordinary course of business. In accordance with SFAS No. 5, 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 anticipated to have a material adverse effect on our consolidated financial position, results of
operations, or cash flows. However, the ultimate outcome of litigation is unpredictable and actual results could be materially different from our estimates. We record anticipated recoveries under applicable insurance contracts when we are assured of
recovery.

The Food & Drug Administration (FDA) and the United
States Department of Justice are continuing to conduct an investigation involving our SYSTEM 1® sterile processing system. We received requests for documents in connection with the
investigation. We continue to respond to these requests and cooperate with the government agencies regarding this matter. There can be no assurance that the ultimate outcome of the investigation will not result in an action by the government
agencies or that the government agencies will not initiate administrative proceedings, civil proceedings or criminal proceedings, or any combination thereof, against us.

The Internal Revenue Service (IRS) routinely conducts audits of our federal income tax returns. During the fourth quarter of fiscal year 2006, we reached a settlement with the IRS with respect to federal
income tax

returns for the fiscal years 1997 and 1998 that were previously in appeals, and entered the appeals phase relative to audit results for fiscal years 1999
through 2001. The IRS began an audit of fiscal years 2002 through 2005 in fiscal year 2007. We also remain subject to tax authority audits in various other jurisdictions in which we operate.

We record accruals for tax positions taken or expected to be taken in a tax return in accordance with the provisions of FIN No. 48. If we were to
prevail in matters for which accruals have been established, or are required to pay amounts in excess of established accruals, our effective income tax rate in a given financial statement period may be materially impacted.

11. Business Segment Information

We operate and
report in three business segments: Healthcare, Life Sciences, and STERIS Isomedix Services.

Our Healthcare segment is a global provider of
capital equipment and accessories used in surgical and critical care environments, emergency departments, gastrointestinal and sterile processing environments, and in infection control processes. We also manufacture and sell consumable products and
provide services to this healthcare customer base.

Our Life Sciences segment manufactures and sells capital equipment, cleaning
chemistries, and service solutions to pharmaceutical companies, public and private research facilities, government, military, aerospace, transportation, and food and beverage customers.

Our Isomedix Services segment operates through a network of 21 facilities located in North America. We sell a comprehensive array of contract
sterilization services using Gamma Irradiation, Electron Beam Irradiation, and ethylene oxide (EO) technologies. We provide sterilization, microbial reduction, and materials modification services to companies that supply products to the
healthcare, industrial, and consumer products industries.

Operating income (loss) for each segment reflects the full allocation of all
distribution, corporate, and research and development expenses 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 costs to sell products to the Life Sciences segment. The accounting policies for the segments are the same as those for the consolidated Company. Individual facilities, equipment and intellectual properties
are utilized for production for multiple segments at varying levels over time. As a result, an allocation of depreciable assets is not meaningful to segment performance. For the three and six months ended September 30, 2007, revenues from a
single customer did not represent ten percent or more of any segments revenues. Additional information regarding our segments is included in our Annual Report on Form 10-K for the year ended March 31, 2007, filed with the SEC on
May 30, 2007.

13. Repurchases of Common Shares

On July 26, 2007, we announced that the Companys Board of Directors had authorized the repurchase of up to $300,000 in shares of our common
stock, replacing a previous authorization to repurchase up to 3,000,000 common shares under which 1,886,869 shares remained available for repurchase. This new common share repurchase authorization does not have a stated maturity date. Under this new
authorization, we may purchase shares from time to time through open market purchases or privately negotiated transactions, including transactions pursuant to Rule 10b5-1 plans.

During the first half of fiscal 2008, we repurchased 1,953,331 of our common shares for $55,620, representing an average price of $28.47 per common
share, including repurchases of 41,700 of our common shares for $1,144 that were not settled until October 2007.

At September 30,
2007, $265,615 in shares of our common stock remained authorized for repurchase and 6,300,991 common shares were held in treasury.

14. Share-Based
Compensation

STERIS has a long-term incentive plan that makes available up to 6,600,000 common shares for grant 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, and restricted share units, or other forms permitted by the plan. STERIS previously granted stock options
under various other plans. Stock options provide the right to purchase

our common shares at the market price on the date of grant, subject to the terms of option plans and agreements. Generally, stock options granted become
exercisable in 25% increments 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 ceases to be employed by us. Certain option agreements
have provisions that provide for an adjustment to the normal vesting schedule allowing the options to vest on a prorated basis as defined by the agreement in the event of employment termination. Restricted shares and restricted share units generally
cliff vest over an approximately three-year period. As of September 30, 2007, 5,521,794 shares remain available for grant under the long-term incentive plan.

On April 1, 2006, we adopted Statement of Financial Accounting Standard No. 123 (revised 2004) (SFAS No. 123R), Share-Based Payment, using the modified prospective transition
method. 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.

Under the modified prospective transition method, compensation cost recognized in the first six months of fiscal 2008 and fiscal 2007 includes
(a) compensation cost for all share-based compensation granted, but not yet vested, as of April 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of Statement of Financial Accounting Standards
No. 123 (SFAS No. 123), Accounting for Stock-Based Compensation, and (b) compensation cost for all share-based compensation granted on or subsequent to April 1, 2006, based on the grant date fair value
estimated in accordance with the provisions of SFAS No. 123R.

Total share based compensation expense recognized during the second
quarter and first half of fiscal 2008 was $2,554 and $4,169, respectively, before income taxes ($992 and $1,568, respectively, net of income taxes). Total share based compensation expense recognized during the second quarter and first half of fiscal
2007 was $3,693 and $5,785, respectively, before income taxes ($2,268 and $3,553, respectively, net of income taxes). The effect of the adoption of SFAS No. 123R on the first half of fiscal 2008 and fiscal 2007 results is not indicative of the
effect on the second half of each fiscal year, as approximately $660 and $1,784 of the stock compensation expense recorded in the first half of fiscal 2008 and fiscal 2007, respectively, was attributable to the accelerated recognition of expense for
certain employees that are or will become eligible for retirement during the vesting period.

The fair value of share based compensation
awards was estimated at their grant date using the Black-Scholes-Merton option pricing model. This model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable,
characteristics that are not present in our grants. If the model permitted consideration of the unique characteristics of employee stock options, the resulting estimate of the fair value of the stock options could be different.

The following weighted-average assumptions were used for options granted during the first half of fiscal 2008 and fiscal 2007:



|                                 |  |             |  |

|                                 |  | Fiscal 2008 |  | Fiscal 2007
|Risk-free interest rate          |  | 5.04%       |  | 4.73%      
|Expected life of options         |  | 5.53 years  |  | 6 years    
|Expected dividend yield of stock |  | 0.93%       |  | 0.65%      
|Expected volatility of stock     |  | 29.66%      |  | 34.29%

The risk-free interest rate is based upon the U.S. Treasury yield curve at the time of grant. The
expected life of options is reflective of historical experience, vesting schedules and contractual terms. The expected dividend yield of stock represents our best estimate of the expected future dividend yield. The expected volatility of stock is
derived by referring to our historical stock prices over a timeframe similar to that of the expected life of the grant. We applied an estimated forfeiture rate of 2.2 percent for fiscal 2007 through the first quarter of fiscal 2008, then 2.49
percent beginning in the second quarter of fiscal 2008. 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 expected life and expected forfeiture rate used for options granted in fiscal 2008 and fiscal 2007 to our former Chief Executive Officer (CEO) were
adjusted based on the terms of the employment agreements with the former CEO entered into in May 2007 and September 2006. The assumptions used above are reviewed at the time of each significant option grant, or at least annually.

Stock option activity for the first half of fiscal 2008 is as follows:

stock option exercises during the first half of fiscal 2008 and fiscal 2007, respectively.

The weighted average grant date fair value of
share-based compensation grants was $9.44 and $9.75 for the first half of fiscal 2008 and fiscal 2007, respectively. The weighted average grant date fair value of share-based compensation granted to the former CEO was adjusted based on the terms of
the employment agreements with the former CEO entered into in May 2007 and September 2006.

(dollars in thousands, except per share amounts)



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 total intrinsic value of restricted shares that vested during the first half of fiscal 2008 and fiscal 2007 was $71 and
$34, respectively.

As of September 30, 2007, there was $11,991 of total unrecognized compensation cost related to non-vested
share-based compensation granted under our share-based compensation plans. The cost is expected to be recognized over a weighted average period of 1.73 years.

15. Financial and Other Guarantees

We generally offer a limited parts and labor warranty on capital equipment. The specific
terms and conditions of those warranties vary depending on the product sold and the country where we conduct business. We record a liability for the estimated cost of product warranties at the time product revenues are recognized. The amounts we
expect to incur on behalf of our customers for the future estimated cost of these warranties are recorded as a current liability on the accompanying Consolidated Balance Sheets within Accrued expenses and other. Factors that affect the
amount of our warranty liability include the number and type of installed units, historical and anticipated rates of product failures, and material and service costs per claim. We periodically assess the adequacy of our recorded warranty liabilities
and adjust the amounts as necessary.

Changes in our warranty liability during the first half of fiscal 2008 were as follows:



|                                    |  |   |        |  
|----------------------------------- |  | - | ------ | -
|Balance, March 31, 2007             |  | $ | 5,893  |  
|Warranties issued during the period |  |   | 6,128  |  
|Settlements made during the period  |  |   | (5,489 | )
|                                    |  |   |        |  
|Balance, September 30, 2007         |  | $ | 6,532  |  
|                                    |  |   |        |  

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 $18,428 and $16,751 as of September 30, 2007 and March 31, 2007, 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. Foreign Currency Forward Contracts

From time to time, we enter into forward contracts to hedge potential foreign currency gains and losses that arise from assets and liabilities denominated
in foreign currencies, including inter-company transactions. We do not use derivative financial instruments for speculative purposes. These contracts are marked to market, with gains and losses recognized on the accompanying Consolidated Statements
of Income within Selling, general, and administrative expenses. At September 30, 2007, we did not hold any foreign currency forward contracts.

17. Business Dispositions

On October 31, 2005, we sold our freeze dryer (lyophilizer) product line to GEA Group of Germany for 20.8 million euros (approximately $25,161). As a result of the sale, we recognized an after-tax gain
$7,292. The gain recognized through September 30, 2006 was preliminary because the purchase price was subject to post-closing adjustments. The freeze dryer product line, based in Cologne, Germany, was part of our Life Sciences segment. The gain
from the sale of this product line, recorded during the first half of fiscal 2007, of $627 is presented in our consolidated financial statements as a discontinued operation, net of tax.

18. Subsequent Events

On September 10, 2007, we announced that the Companys Board of
Directors appointed a new CEO, effective October 1, 2007. In connection with his employment, effective October 15, 2007, the Company awarded the new CEO, a total of 135,000 stock options at an exercise price of $28.32 per share and 45,000
restricted stock units with a grant date fair value of $28.32 per share.

Effective November 1, 2007, the Company awarded a total of
4,000 stock options at an exercise price of $27.45 per share and 1,400 restricted shares with a grant date fair value of $27.45 per share to certain officers of the Company.

On October 24, 2007, we announced that the Companys Board of Directors had declared a quarterly cash dividend in the amount of $0.06 per
common share, payable on December 12, 2007, to shareholders of record as of November 14, 2007.

Subsequent to September 30,
2007 and prior to November 7, 2007, we repurchased 427,900 of our common shares for an aggregate of $12,071, representing an average price of $28.21 per common share.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

STERIS Corporation

We have reviewed the consolidated balance sheet of STERIS Corporation and subsidiaries as of September 30, 2007, and the related consolidated
statements of income for the three-month and six-month periods ended September 30, 2007 and 2006, and the consolidated statements of cash flows for the six-month periods ended September 30, 2007 and 2006. 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, 2007, 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 24, 2007, 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, 2007, 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 the second quarter and first half of fiscal 2008 and 2007;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | 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, it may be helpful to refer to information in our consolidated financial statements, which present the results of our operations for the second quarter and first half of fiscal 2008 and fiscal
2007. 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 have used the following financial measures in the context of this report: backlog; debt to capital; and days sales outstanding. We define these financial measures as follows:



| |  |  | Backlog - We define backlog as the amount of unfilled capital 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 capital - We define debt to 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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Days sales outstanding (DSOs) - We define DSO as the average collection period for accounts receivable. It is calculated as net accounts receivable
divided by the trailing four quarters 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 (used in) operating activities as presented in the Consolidated Statements of Cash Flows
less purchases of property, plant, equipment, and intangibles, net, plus proceeds from the sale of property, plant, equipment, and intangibles, which is also presented in the Consolidated Statements of Cash Flows. We use this measure to gauge our
ability to fund future growth outside of core operations, repurchase common shares, pay cash dividends, and reduce debt. The following table reconciles the calculations of our free cash flow for the six months ended September 30, 2007 and 2006:

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 and divestitures.

We have presented these financial measures because we believe that meaningful analysis of our financial
performance is enhanced by an understanding of certain additional factors underlying that performance. These financial measures should not be considered alternatives to measures required by U.S. GAAP. Our calculations of these measures may differ
from calculations of similar measures used by other companies.

Revenues - Defined. As required by 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 - Our revenues are presented 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; surgical lights, tables and ceiling management systems; 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
capital equipment, as well as revenues generated from contract sterilization offered through our Isomedix Services 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; and surgical lights,
tables and ceiling management systems.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.

We
participate in industries that currently benefit from strong underlying demand, with the bulk of our revenues derived from the healthcare and pharmaceutical industries. As such, much of the growth in our markets is driven by the aging of the
population throughout the world, as an increasing number of individuals are entering their prime healthcare consumption years. In addition, each of our core industries also are benefiting from specific trends that drive growth. Within the healthcare
market, there is increased concern regarding the level of hospital-acquired infections around the world. The pharmaceutical industry has been impacted by increased FDA scrutiny of cleaning and validation processes, mandating that manufacturers
improve their processes. In the contract sterilization industry, where our Isomedix segment competes, a trend toward the outsourcing of sterilization services continues to drive growth.

Beyond our core markets, infection-control issues are becoming a global concern, and emerging threats have gained prominence in the news. Through the
Life Sciences segment, we are actively pursuing new opportunities

to adapt our proven technologies to meet the needs of emerging applications such as defense, aerospace, food and beverage, and industrial decontamination.

Fiscal 2008 second quarter and first half revenues were $295.0 million and $575.9 million, respectively, representing increases of 4.0%
and 5.0%, respectively, from the same prior year periods. Revenues in the second quarter and first half of fiscal 2008 reflect growth in all three business segments.

Our gross margin percentages were 41.9% and 42.1% for the second quarter and first half of fiscal 2008, which was flat compared to the same prior year quarter and a decrease of 20 basis points from the first half of
fiscal 2007. Gross margins during both fiscal 2008 periods were unfavorably impacted by increases in the costs of raw materials but benefited from price increases and productivity improvements.

Free cash flow was $31.2 million in the first half of fiscal 2008 compared to negative $3.2 million in the prior year first half. The fiscal 2007 first
half negative free cash flow of $3.2 million was a result of working capital changes, including approximately $27.6 million in payments to the IRS for taxes previously recognized. Our debt-to-capital ratio increased to 14.0% at September 30,
2007 from 11.6% at March 31, 2007 reflecting increased borrowings utilized to fund working capital changes and common share repurchases. During the first half of fiscal 2008, we paid for the repurchase of approximately 1.9 million common
shares at an average purchase price per share of $28.50. We also declared and paid cash dividends totaling $0.11 per common share in the first half of fiscal 2008. In the first half of fiscal 2007, we declared and paid cash dividends totaling $0.08
per common share.

On July 26, 2007, we announced that the Companys Board of Directors increased the quarterly cash dividend by
20% and declared a quarterly cash dividend in the amount of $0.06 per common share, which was paid on September 12, 2007, to shareholders of record as of August 15, 2007.

Additional information regarding the Companys fiscal 2008 second quarter and first half financial performance is included in the subsection below
titled Results of Operations.

Matters Affecting Comparability

Accounting for Uncertain Tax Positions. On April 1, 2007, we adopted FIN No. 48, which provides guidance for the recognition
threshold and measurement attribute for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. In accordance with FIN No. 48, we recorded a cumulative-effect adjustment of $8.4 million,
increasing our liability for unrecognized tax benefits, interest, and penalties and reducing the April 1, 2007 balance of retained earnings.

Additional information regarding our adoption of FIN No. 48 is included in note 1 titled, Nature of Operations and Summary of Significant Accounting Policies, and in note 8 titled, Income Tax Expense, of our
accompanying consolidated financial statements.

Restructuring. On January 30, 2006, we announced that the manufacturing
portion of our Erie, Pennsylvania operations would be transferred to Mexico to reduce production costs and improve our competitive position. Plans for other restructuring actions designed to reduce operating costs within the ongoing operations of
both the Healthcare and Life Sciences segments also were approved at that time.

During the second quarter and first half of fiscal 2008,
we recorded pre-tax expenses of $1.4 million and $3.3 million, including $0.7 million and $2.1 million classified as restructuring expenses, respectively. During the second quarter and first half of fiscal 2007, we recorded pre-tax expenses of $3.3
million and $5.7 million, including $1.2 million and $2.3 million classified as restructuring expenses, respectively. The expenses recorded in each year primarily related to accelerated depreciation of assets, compensation and severance and
termination benefits related to the transfer of our Erie, Pennsylvania manufacturing operations to Monterrey, Mexico.

Additional
information regarding our restructuring actions is included in our Annual Report on Form 10-K for the year ended March 31, 2007, filed with the SEC on May 30, 2007.

Business Dispositions. On October 31, 2005, we sold our freeze dryer (lyophilizer) product line to GEA Group of Germany for
20.8 million euros (approximately $25.2 million). As a result of the sale, we recognized an after-tax gain of approximately $7.3 million. The gain recognized through September 30, 2006 remained

subject to adjustment as transaction costs were finalized. The freeze dryer product line, based in Cologne,

Germany, was part of our Life Sciences segment. The gain from the sale of this product line, recorded through the first half of fiscal 2007, of $0.6 million
is presented in our financial statements as a discontinued operation, net of tax.

International Operations. Since we conduct
operations outside of the United States using various foreign currencies, our operating results are impacted by foreign currency movements relative to the U.S. dollar. During the second quarter of fiscal 2008, our revenues were favorably impacted by
$3.2 million, or 1.1%, and income before taxes was favorably impacted by $0.6 million, or 2.6%, compared with the same period in fiscal 2007, as a result of foreign currency fluctuations. During the first half of fiscal 2008, our revenues were
favorably impacted by $5.4 million, or 0.9%, and income before taxes was unfavorably impacted by $1.1 million, or 2.4%, as compared to the same prior year period, as a result of foreign currency fluctuations.

Results of Operations

In the following subsections,
we discuss our earnings and the factors affecting them for the second quarter and first half of fiscal 2008 compared with the same fiscal 2007 periods. We begin with a general overview of our operating results and then separately discuss earnings
for our operating segments.

Revenues. The following table contains information regarding our revenues for the second quarter
and first half of fiscal 2008 and 2007:

Quarter over Quarter Comparison

Revenues increased $11.5 million, or 4.0%, to $295.0 million for the quarter ended September 30, 2007, as compared to $283.5 million for the
comparable prior year quarter. As compared to the second quarter of fiscal 2007, recurring revenues increased 7.4%, driven by increases in consumable revenues and service revenues of 6.4% and 8.1%, respectively. Capital revenues decreased 0.9%
quarter over quarter as increased revenues internationally were offset by a decline in the United States.

International revenues increased
$8.2 million, or 13.9%, to $67.5 million, for the quarter ended September 30, 2007, as compared to $59.3 million for the comparable prior year quarter. Recurring revenues grew within both the Healthcare and Life Sciences segments with increases
of 19.1% and 25.1%, respectively, over the comparable prior year quarter. International revenues were also positively impacted by capital equipment growth in the Healthcare segment with an increase of 16.2% over the comparable prior year quarter.

United States revenues increased $3.3 million, or 1.4%, to $227.5 million, for the quarter ended September 30, 2007, as compared to
$224.2 million for the comparable prior year quarter. United States revenues were positively impacted by recurring revenue growth in all three business segments with increases of 5.0%, 7.3%, and 5.3% in the Healthcare, Life Sciences, and Isomedix
segments, respectively. The strength in recurring revenues was partially offset by a decline of 18.7% in capital revenues in the Life Sciences segment.

Year over Year Comparison

Revenues increased $27.3 million, or 5.0%, to $575.9 million for the first half of fiscal
2008, as compared to $548.6 million during the first half of fiscal 2007. As compared to the first half of fiscal 2007, recurring revenues increased 7.7%, reflecting growth in consumable revenues and service revenues, with increases of 6.1% and
8.7%, respectively. Capital revenues increased $1.7 million period over period, as increases in international revenues more than offset the decline in United States revenues.

International revenues for the first half of fiscal 2008 amounted to $126.5 million, an increase of $13.1 million, or 11.5%, as compared to the first
half of fiscal 2007. Fiscal 2008 year-to-date international revenues were positively impacted by strong recurring revenue growth within both the Healthcare and Life Sciences segments, with increases of 16.1% and 17.5%, respectively.

United States revenues for the first half of fiscal 2008 amounted to $449.4 million, an increase of $14.3 million, or 3.3%, as compared to the first half
of fiscal 2007. Strong underlying demand for our service offerings and consumable products more than offset declines in capital revenues in both the Healthcare and Life Sciences segments.

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

Our gross profit (margin) is affected by the volume, pricing, and mix of our products and
services, as well as the costs associated with the products and services that are sold. Gross margin for the second quarter of fiscal 2008 amounted to 41.9%, which was flat as compared to the same prior year period. In the second quarter of fiscal
2008, we benefited from price increases and labor savings from the transfer of our manufacturing operations from Erie, Pennsylvania to Monterrey, Mexico but the benefits were offset by increases in raw material costs. For the first half of fiscal
2008, gross margin amounted to 42.1%, representing a decrease of 20 basis points as compared to the same prior year period, as the benefits of price increases and productivity improvements were more than offset by increases in raw material costs.

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 60 basis
points to 29.8% for the second quarter of fiscal 2008 and increased 90 basis points to 30.3% for the first half of fiscal 2008, as compared to the same prior year periods. The increase in SG&A in both fiscal 2008 periods reflects continued
investments in the development and marketing of new products along with added selling expenses relating to our growth initiatives.

As a
percentage of total revenues, research and development expenses were 2.9% and 3.1% for the three- and six-month periods ended September 30, 2007, respectively, as compared to 2.9% and 3.0%, respectively, for the same prior year periods. For the
three- and six-month periods ended September 30, 2007, research and development expenses increased 3.0% and 6.7% to $8.5 million and $17.8 million, respectively, as compared to $8.3 million and $16.7 million, respectively, during the same prior
year periods. Research and development expenses are influenced by the number and timing of in-process projects and labor hours and other costs associated with these projects. Our research and development initiatives continue to emphasize new product
development, product improvements, and the development of new technological innovations. During the second quarter and first half of fiscal 2008, our investments in research and development continued to be focused on, but were not limited to,
enhancing capabilities of delivery systems in the defense and industrial areas, 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 as required under the provisions of SFAS
No. 146. In addition, we assess the property, plant and equipment associated with the related facilities for impairment under SFAS No. 144. Asset impairment and accelerated depreciation expenses primarily relate to an adjustment to the
carrying value of the related facilities to their estimated fair value. In addition, the remaining useful lives of other property, plant and equipment associated with the related operations were re-evaluated based on the respective restructuring
plan, resulting in the acceleration of depreciation and amortization of certain assets.

##### Table of Contents

During the second quarter and first half of fiscal 2008, we recorded pre-tax expenses of $1.4 million and
$3.3 million, including $0.7 million and $2.1 million classified as restructuring expenses, respectively. During the second quarter and first half of fiscal 2007, we recorded pre-tax expenses of $3.3 million and $5.7 million, including $1.2 million
and $2.3 million classified as restructuring expenses, respectively. The expenses primarily relate to accelerated depreciation of assets, asset impairment costs, compensation and severance and termination benefits related to the transfer of our
Erie, Pennsylvania manufacturing operations to Monterrey, Mexico, which was part of the Fiscal 2006 Restructuring Plan. The restructuring expenses recorded during the second quarter and first half of fiscal 2008 and fiscal 2007 are summarized in the
following tables:

The costs incurred during the second quarter and first half of fiscal 2008 and fiscal 2007 are
primarily associated with the Healthcare business segment. Since the inception of the Fiscal 2006 Restructuring Plan, we have incurred restructuring expenses of $32.3 million, with restructuring expenses of $31.9 million and $0.4 million related to
the Healthcare and Life Sciences segments, respectively.

We anticipate incurring approximately an additional $2.8 million in restructuring
expenses during the remainder of fiscal 2008 in connection with the transfer of the manufacturing operations to Mexico. Restructuring expenses to be incurred include compensation and benefits, severance, accelerated depreciation and other expenses.

Liabilities related to the Fiscal 2006 Restructuring Plan activities are recorded as current liabilities on the accompanying Consolidated
Balance Sheets within Accrued expenses and other. The following table summarizes our liabilities related to these restructuring activities:

During the third quarter of fiscal 2007, we adopted a restructuring plan related to certain of our
European operations (the European Restructuring Plan). For the three and six months ended September 30, 2007, we did not incur any additional restructuring expenses related to the European Restructuring Plan and settled certain
termination benefits for less than originally expected. Since the inception of the plan, we have incurred

Interest expense decreased $0.9 million and $1.4 million during the second quarter and first half
of fiscal 2008, respectively, as compared to the same prior year periods as a result of lower average debt levels and lower average interest rates during both fiscal 2008 periods. Interest and miscellaneous income decreased $0.2 million and $0.4
million for the second quarter and first half of fiscal 2008, respectively, as compared to same prior year periods. This decrease was due to lower cash balances during both periods in fiscal 2008, which resulted in a smaller amount of interest
earnings on those balances.

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 for continuing operations for the three- and six-month periods ended September 30, 2007 were 37.4% and 37.0%, respectively, as compared to 34.5% and 38.3%, respectively, for
the same prior year periods. The lower effective income tax rate for the second quarter of fiscal 2007 resulted principally from discrete item adjustments to recognize additional deferred tax assets related to foreign tax credits. During the first
half of fiscal 2008, we benefited from discrete item adjustments resulting from income tax audits in the United States and Canada.

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.

million for the quarter ended September 30, 2007, compared with $197.1 million for the second quarter of fiscal 2007. The increase in Healthcare revenues was driven by strong growth in service and consumable revenues, with increases of 9.1% and
6.0%, respectively. Healthcare capital revenues increased 1.8% for the second quarter of fiscal 2008 as compared to the same prior year period. At September 30, 2007, the Healthcare segments backlog amounted to $94.0 million, representing
an increase of $24.5 million, or 35.2%, compared to the June 30, 2007 level and an increase of $11.8 million, or 14.3%, compared to the September 30, 2006 level.

period. Healthcare revenues increased $18.1 million, or 4.7%, to $402.3 million for the six months ended September 30, 2007, as compared to $384.2 million for the same prior year period. The increase is attributable to an increase in recurring
revenues, particularly in the United States and Canadian markets, with a combined growth in consumable revenues and service revenues of 4.3% and 7.7%, respectively. Healthcare capital revenues for the first six months of fiscal 2008 grew 1.5% as

1.1%, to $53.5 million for the quarter ended September 30, 2007, as compared to $52.9 million for the second quarter of fiscal 2007. The increase in Life Sciences revenues was driven by increases in service and consumable revenues of 12.8% and
8.5%, respectively. This growth was partially offset by an 11.7% decline in capital revenues. However, strong demand late in the quarter caused backlog to increase to $57.8 million at September 30, 2007, an increase of $11.3 million, or 24.3%,
compared to the backlog of $46.5 million at June 30, 2007 and an increase of $13.5 million, or 30.6%, compared to the September 30, 2006 level.

NM- Not meaningful

Segment operating income (loss) is calculated as the segments gross profit less direct expenses and indirect cost allocations, which results in the
full allocation of all distribution, corporate, and research and development expenses. Corporate cost allocations are based on each segments portion of revenues, headcount, or other variables in relation to the total company. In addition, the
Healthcare segment is responsible for the management of all but one manufacturing facility and uses standard costs to sell products to the Life Sciences segment.

Healthcare Segment

The Healthcare segments operating income decreased $1.9 million and $7.8 million for the
second quarter and first six months of fiscal 2008, respectively, as compared to the same prior year periods. The segments operating margins were 9.0% and 8.4% for the second quarter and first half of fiscal 2008, respectively, representing
decreases of 140 basis points and 240 basis points, respectively, as compared to prior year periods. Improved pricing and productivity improvements gained from the transfer of manufacturing operations from Erie, Pennsylvania to Monterrey, Mexico
were partially offset in the second quarter and more than offset in the first half of fiscal 2008 by significant increases in raw material costs over the same prior year periods. The Healthcare segment also incurred higher operating costs related to
continued investments in the development and marketing of new products and added selling expenses related to growth initiatives.

Life Sciences
Segment

The Life Sciences segment had operating income of $1.4 million and $0.6 million for the second quarter and first six months
of fiscal 2008, respectively, as compared to operating income of $0.3 million and an operating loss of $1.0 million for the same prior year periods. The improvement in operating performance was primarily driven by higher gross margin service and
consumable revenues as compared to the same prior year periods.

STERIS Isomedix Services Segment

The STERIS Isomedix Services segments operating income increased $0.7 million and $2.2 million for the second quarter and first six months of fiscal
2008, respectively, as compared to the same prior year periods. The segments operating margins were 18.7% and 19.5% for the second quarter and first half of fiscal 2008,

Net Cash Provided by Operating Activities. The net cash provided by our operating
activities was $52.7 million for the first six months of fiscal 2008 compared with $18.3 million for the first six months of fiscal 2007. The following discussion summarizes the significant changes in our operating cash flows:



| |  |  | Non-cash items- Our non-cash items include depreciation, depletion, and amortization, share-based compensation expense, changes in deferred income taxes, and other
items. Non-cash items were $33.8 million for the first six months of fiscal 2008 compared with $28.5 million for the first six months of fiscal 2007. Significant changes in these items for the first half of fiscal 2008 as compared to the same prior
year period are summarized below:
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Depreciation, depletion, and amortization- Depreciation, depletion, and amortization is the most significant component of non-cash items. This expense totaled $31.5
million and $29.7 million for the first six months of fiscal 2008 and 2007, respectively. The $1.8 million increase in this expense was primarily the result of recording accelerated depreciation and loss on the disposal of certain assets included in
the Fiscal 2006 Restructuring Plan.

##### Table of Contents

| |  |  | Share-based compensation expense- We recorded non-cash share-based compensation expense of $4.2 million and $5.8 million for the first six months of fiscal 2008 and
fiscal 2007, respectively. The decline of $1.6 million reflects a decline in the number of options granted and subject to amortization in the current fiscal year.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deferred income taxes- Our deferred income tax benefits increased $2.6 million for the first half of fiscal 2008, compared with an increase of $7.2 million for the
first half of fiscal 2007 due to the timing and recognition of settlements.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Working Capital- Excluding the impact of foreign currency translation adjustments, changes to our working capital totaled a negative $10.3 million and a negative
$41.3 million during the first six months of fiscal 2008 and fiscal 2007, respectively. Significant changes in our working capital for the first half of fiscal 2008 as compared to the first half of fiscal 2007 are summarized below:
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts receivable, net- Our net accounts receivable balances decreased $43.7 million during the first six months of fiscal 2008 as compared to a decrease of $43.6
million for the same prior year period. Our accounts receivable balances may change from period to period due to the timing of revenues and customer payments. Accounts receivable days sales outstanding decreased to 63 days at September 30,
2007, from 77 days at March 31, 2007 and remained flat compared to the September 30, 2006 level. The decrease in the balance of accounts receivable and days sales outstanding from the March 31, 2007 level is reflective of lower
revenues for the second quarter of fiscal 2008 as compared to the fourth quarter of fiscal 2007 and improvements in collections.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Inventories, net- Our net inventory balances increased $20.8 million during the first six months of fiscal 2008 as compared to an increase of $27.1 million for the
same prior year period. Inventory balances in fiscal 2008 reflect higher levels of inventory related to the impact of increased raw material costs, new product and service initiatives, and targeted inventory production levels in anticipation of
increased volumes in the second half of fiscal 2008.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other current assets- Our other current assets primarily consist of prepaid expenses for insurance, taxes, and other general corporate items. Other current assets
decreased $0.6 million during the first six months of fiscal 2008. The increase of $19.4 million during the first half of fiscal 2007 was primarily driven by a portion of the tax payment made during the first quarter of fiscal 2007 which remains on
deposit with the IRS, subject to final resolution of certain matters under audit.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts payable, net- Our net accounts payable balances decreased $15.8 million during the first six months of fiscal 2008 as compared to a decrease of $21.3
million for the same prior year period. 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- Our net accruals and other liabilities balances decreased $16.8 million during the first six months of fiscal 2008, reflecting payments
made in the first quarter of fiscal 2008 against amounts accrued in fiscal 2007 for incentive compensation and federal income taxes. During the first half of fiscal 2007, our net accruals and other liabilities balances decreased $17.1 million,
primarily due to the application of approximately $9.9 million in tax payments made in the first quarter to open tax years, a $3.1 million contribution we made to our United States defined benefit pension plan in September 2006, and an additional
$3.0 million for the settlement of a fiscal 2006 accrual for the termination of certain long-term marketing contracts. Cash flows related to our accruals and other liabilities balances will change from period to period due to the timing of accruals
and payments under our incentive compensation programs. Accruals under our various incentive compensation programs rise during the course of the fiscal year and decline significantly in the first fiscal quarter as payments are made under these
programs. Changes in accruals for deferred revenues also contribute to the increase or decrease in these balances.

| |  |  | Net proceeds under credit facilities- We borrowed $24.1 million and $32.6 million under our revolving credit facilities during the first six months of fiscal 2008
and fiscal 2007, respectively. Proceeds borrowed are generally used to fund share repurchases and working capital changes. Working capital changes during the first half of fiscal 2007 included a $27.6 million payment to the IRS for taxes previously
incurred.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Repurchases of common shares- The Companys Board of Directors has provided authorization to repurchase the Companys common shares. During the first half
of fiscal 2008, we paid for the repurchase of 1,911,631 of our common shares at an average purchase price of $28.50 per common share. During the first half of fiscal 2007, we paid for the repurchase of 2,585,300 of our common shares at an average
purchase price of $23.06 per common share.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash dividends paid to common shareholders- During the first six months of fiscal 2008 and fiscal 2007, we paid cash dividends totaling $0.11 and $0.08 per
outstanding common share, respectively. Total cash dividends paid during the first half of fiscal 2008 and fiscal 2007 amounted to $7.1 million and $5.3 million, respectively.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock option and other equity transactions, net- We receive cash for issuing common shares under our various employee stock option programs. During the first six
months of fiscal 2008 and 2007, we received cash proceeds totaling $10.6 million and $2.4 million, respectively, under these programs.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Cash Flow Measures. Free cash flow was $31.2 million in the first half of fiscal 2008 compared to negative $3.2 million in the prior year first half. The fiscal 2007 first half negative free cash flow of
$3.2 million was a result of working capital changes, including approximately $27.6 million in payments to the IRS for taxes previously recognized. Our debt-to-capital ratio increased to 14.0% at September 30, 2007 from 11.6% at March 31,
2007 reflecting increased borrowings utilized to fund working capital changes and common share repurchases.

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, 2007, filed with the SEC on
May 30, 2007. Our commercial commitments were approximately $30.5 million at September 30, 2007 reflecting an increase of $4.6 million in surety bonds and other commercial commitments from March 31, 2007. Our contractual commitments
have not changed materially from March 31, 2007.

On September 13, 2007, we signed the Second Amended and Restated Credit
Agreement (the Credit Agreement) with KeyBank National Association, as administrative agent for the lending institutions that are



37

##### Table of Contents

parties to the Credit Agreement (the Agent), and the other lenders that may from time to time be a party to the Credit Agreement. This Credit
Agreement amends, restates, and replaces our Amended and Restated Credit Agreement dated March 29, 2004, as amended, which was to mature in June 2010. The Credit Agreement matures on September 13, 2012 and provides $400.0 million of
credit, which may be increased by up to an additional $100.0 million in specified circumstances, for borrowings and letters of credit. A floating interest rate is applied to amounts borrowed as defined in the Credit Agreement or a fixed rate may be
applied based on the Eurodollar Rate or other defined currency rate, plus a margin based on our leverage ratio. Interest is payable quarterly or at the end of the interest period, if shorter. We may prepay floating rate loans without paying a
penalty, but we may be required to pay a penalty for prepaying fixed rate loans. The Credit Agreement also allows us to make short term swing loan borrowings not to exceed $35.0 million, with an interest rate equal to the Agents cost of funds
plus a margin. Our obligations under the Credit Agreement are unsecured but guaranteed by our material domestic subsidiaries.

At
September 30, 2007, the maximum amount available under this Credit Agreement was $354.6 million. The maximum aggregate borrowing limit of $400.0 million under the Credit Agreement is reduced by outstanding amounts ($24.1 million) and letters of
credit issued ($21.3 million) under a sub-limit within the Credit Agreement.

Cash Requirements.Currently, we intend to use our
existing cash and cash equivalent balances, cash generated from operations, and our existing Credit Agreement 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.We adopted FIN No. 48 effective April 1, 2007, which provides
guidance for the recognition and measurement of tax positions taken or expected to be taken on a tax return. In accordance with FIN No. 48, we recorded a cumulative-effect adjustment of $8.4 million, increasing our liability for unrecognized
tax benefits, interest, and penalties and reducing the April 1, 2007 balance of retained earnings.

Additional information regarding
our adoption of FIN No. 48 is included in note 1 titled, Nature of Operations and Summary of Significant Accounting Policies, and in note 8 titled, Income Tax Expense of our accompanying consolidated financial
statements.

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, 2007, filed with the SEC on May 30, 2007. Our critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2007, other than for the adoption of FIN No. 48
as described above.

Contingencies.We are involved in various patent, product liability, consumer, environmental, tax proceedings
and claims, governmental investigations, and other legal and regulatory proceedings that arise from time to time in the ordinary course of business. In accordance with Statement of Financial Accounting Standards No. 5, Accounting for
Contingencies, 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 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 effect

on our consolidated financial position, results of operations, or cash flows. However, the ultimate outcome of litigation is unpredictable and actual results
could be materially different from our estimates. We record anticipated recoveries under applicable insurance contracts when assured of recovery.

The IRS routinely conducts audits of our federal income tax returns. During the fourth quarter of fiscal year 2006, we entered the appeals phase relative to audit results for fiscal years 1999 through 2001. The IRS began an audit of fiscal
years 2002 through 2005 in fiscal year 2007. We also remain subject to tax authority audits in various other jurisdictions in which we operate.

We record accruals for tax positions taken or expected to be taken in a tax return in accordance with the provisions of FIN No. 48. If we were to prevail in matters for which accruals have been established, or is required to pay
amounts in excess of established accruals, our effective income tax rate in a given financial statement period could be materially impacted.

International Operations.Since we conduct operations outside the United States using various foreign currencies, our operating results are impacted by foreign currency movements relative to the U.S. dollar. During the second quarter
of fiscal 2008, our revenues were favorably impacted by $3.2 million, or 1.1%, and income before taxes was favorably impacted by $0.6 million, or 2.6%, when compared to the same period in fiscal 2007, as a result of foreign currency movements
relative to the U.S. dollar. During the first half of fiscal 2008, our revenues were favorably impacted by $5.4 million, or 0.9%, and income before taxes was unfavorably impacted by $1.1 million, or 2.4%, when compared to the same period in fiscal
2007, as a result of foreign currency movements relative to the U.S. dollar. We have taken steps to reduce the foreign currency volatility by converting foreign currency denominated inter-company loans to equity for certain foreign legal entities.
We cannot predict future changes in foreign currency exchange rates or the effect they will have on our operations.

Forward-Looking
Statements.This Quarterly Report on Form 10-Q may contain statements concerning certain trends, expectations, forecasts, estimates, or other forward-looking information affecting or relating to us or our industry that are intended to qualify
for the protections afforded forward-looking statements under the Private Securities Litigation Reform Act of 1995 and other laws and regulations. Forward-looking statements speak only as to the date of this report, and may be identified
by the use of forward-looking terms such as may, will, expects, believes, anticipates, plans, estimates, projects, targets,
forecasts, and seeks, or the negative of such terms or other variations on such terms or comparable terminology. Many important factors could cause actual results to be materially different from those in the forward-looking
statements including, without limitation, disruption of production or supplies, changes in market conditions, political events, pending or future claims or litigation, competitive factors, technology advances, and changes in government regulations
or the application or interpretation thereof. Many of these important factors are outside of our control. No assurances can be provided as to any future financial results. Unless legally required, we do 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 be materially different from those in the
forward-looking statements include, without limitation, (a) the potential for increased pressure on pricing or raw material cost that leads to erosion of profit margins, (b) the possibility that market demand will not develop for new
technologies, products or applications, or that our business initiatives will take longer, cost more or produce lower benefits than anticipated, (c) the possibility that application of or compliance with laws, court rulings, regulations,
certifications or other requirements or standards may delay or prevent new product introductions, affect the production and marketing of existing products, or otherwise affect our performance, results, 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 our products and services, (f) the possibility that anticipated cost savings may not be achieved, or that transition, labor, competition, timing, execution, regulatory, governmental or other issues or risks
associated with our expansion, transfer, executive recruitment or retention, or other initiatives may adversely impact our performance, results, or

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the ordinary course of business, we
are subject to interest rate, foreign currency, and commodity risks. Information related to these risks and our management of these exposures is included in Part II, Item 7A, Quantitative and Qualitative Disclosures about Market
Risk, included in our Annual Report on Form 10-K for the year ended March 31, 2007, filed with the SEC on May 30, 2007. Our exposures to market risks have not changed materially since March 31, 2007.

ITEM 4. CONTROLS AND PROCEDURES

Under the supervision of and with the participation of our management,
including the Principal Executive Officer (PEO) and Principal Financial Officer (PFO), we evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and
15d-15(e) promulgated under the Securities Exchange Act of 1934, as of the end of the period covered by this Quarterly Report. Based on that evaluation, including the assessment and input of our management, the PEO and PFO concluded that, as of
September 30, 2007, our disclosure controls and procedures were effective.

There were no changes in our internal control over
financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934, that occurred during the quarter ended September 30, 2007 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

PART IIOTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we may be involved in a number of legal proceedings and claims,
which we believe arise from the ordinary course of our business, given our size, history, complexity, nature of our business, and industries in which we participate. These legal proceedings and claims generally involve a variety of legal theories
and allegations, including without limitation, personal injury (e.g., slip and falls, automobile accidents), product liability (e.g., based on the operation or claimed malfunction of products), product exposure (e.g., claimed exposure to chemicals,
asbestos, contaminants), property damage (e.g., claimed damage due to leaking equipment, fire), economic loss (e.g., breach of contract, other commercial claims), employment (e.g., wrongful termination), and other claims for damage and relief.

The FDA and the United States Department of Justice are continuing an investigation
involving our SYSTEM 1® sterile processing system. We have received requests for documents in connection with the investigation. We continue to respond to these requests and cooperate with
the government agencies regarding this matter. There can be no assurance that the ultimate outcome of the investigation will not result in an action by the government agencies or that the government agencies will not initiate administrative
proceedings, civil proceedings or criminal proceedings, or any combination thereof, against us.

We believe we have adequately reserved for
our current litigation and that the ultimate outcome of pending lawsuits and claims will not have a material adverse effect on our consolidated financial position or results of operations taken as a whole. Due to their inherent uncertainty, however,
there can be no assurance of the ultimate outcome of current or future litigation, proceedings, investigations, or claims or their effect. We presently maintain product liability insurance coverage, and other liability coverage 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 against us.

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

We believe there have been no material recent developments concerning our legal proceedings since March 31, 2007 and no new
material pending legal proceedings are required to be reported.

ITEM 1A. RISK FACTORS

We believe there have been no material changes to the risk factors included in our Annual
Report on Form 10-K for the fiscal year ended March 31, 2007, filed with the SEC on May 30, 2007, that would materially affect our business, results of operations, or financial condition.

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

During the second quarter of fiscal 2008,
we repurchased 1,244,400 of our common shares. These repurchases were pursuant to a single repurchase program which was approved by the Companys Board of Directors and announced on July 26, 2007. This common share repurchase authorization
replaced the common share repurchase authorization of July 27, 2006, under which 1,886,869 shares remained available for repurchase,
