   B. - BASIS OF PRESENTATION

   The accompanying unaudited consolidated condensed financial statements have
   been prepared in accordance with generally accepted accounting principles for
   interim financial information and with the instructions to Form 10-Q and
   Article 10 of Regulation S-X; they do not include all of the information and
   footnotes required by generally accepted accounting principles for complete
   financial statements. Accordingly, the reader of these financial statements
   should refer to the audited consolidated financial statements of STERIS filed
   with the Securities and Exchange Commission as part of STERIS's Form 10-K for
   the year ended March 31, 1999.

   The accompanying consolidated condensed financial statements have been
   prepared in accordance with STERIS's customary accounting practices and have
   not been audited. Management believes that the financial information included
   herein reflects all adjustments necessary for a fair presentation of interim
   results and all such adjustments are of a normal and recurring nature. The
   interim results reported are not necessarily indicative of the results to be
   expected for the fiscal year ending March 31, 2000.

   The balance sheet at March 31, 1999 has been derived from the audited
   financial statements at that date but does not include all of the information
   and footnotes required by generally accepted accounting principles for
   complete financial statements.

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

   D. - COMPREHENSIVE INCOME

   Comprehensive income amounted to $8,913 and $13,683, net of tax, for the
   quarters ended June 30, 1999 and 1998, respectively, a decrease of 34.9%. The
   entire difference between net income and comprehensive income for the periods
   presented result from changes in the cumulative translation adjustment.

   E. - INVENTORIES

   Inventories were as follows:

   The increase in inventories during the period was due to an increase in costs
   to support product sales and anticipated future product sales.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
          (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS) (UNAUDITED)

   F. - FINANCING

   On January 26, 1999, STERIS entered into a $400,000 Credit Facility. The
   Credit Facility includes an unsecured revolver of $250,000 which expires
   January 26, 2002. The remaining $150,000 is an unsecured 364 day facility
   expiring on January 25, 2000, which can be extended annually for 364 days.
   The $400,000 Credit Facility may be used for general corporate purposes and
   will bear interest at either KeyBank National Association's prime rate or at
   LIBOR plus a margin. The Credit Facility contains customary covenants which
   include maintenance of certain financial ratios. At June 30, 1999, the
   outstanding borrowings under the existing Credit Facility were $250,000.

   The Company has now purchased 3.7 million Common Shares as a part of its
   previously announced open market buy-back program, of which 1.54 million
   Common Shares were purchased in the latest quarter, at an average per share
   price of $18.65.

   G. - CONTINGENCIES

   There are various pending lawsuits and claims arising out of the conduct of
   STERIS's business. In the opinion of management, the ultimate outcome of
   these lawsuits and claims will not have a material adverse effect on STERIS's
   consolidated financial position or results of operations. STERIS believes it
   presently maintains a prudent amount of product liability insurance coverage
   and associated deductible levels.

   H. - ACQUISITIONS

   Early in the second quarter fiscal 2000, the Company acquired the assets of
   Quality Sterilization Systems (QSS), a contract sterilization business
   located near Minneapolis, Minnesota. QSS primarily provides contract
   sterilization services for medical device manufacturers in the upper Midwest.
   Also, during the second quarter fiscal 2000, the Company completed the
   acquisition of privately held FoodLabs, Inc. FoodLabs, Inc., located in
   Manhattan, Kansas, provides analytical, product development, and consulting
   services to the food and agricultural industries, with a particular focus on
   food safety. These acquisitions will be accounted for as purchase
   transactions.

                     INDEPENDENT ACCOUNTANTS' REVIEW REPORT

   Board of Directors and Shareholders
   STERIS Corporation

   We have reviewed the accompanying consolidated condensed balance sheet of
   STERIS Corporation and subsidiaries as of June 30, 1999, and the related
   consolidated condensed statements of income and cash flows for the three
   months ended June 30, 1999 and 1998. These financial statements are the
   responsibility of the Company's management.

   We conducted our review in accordance with standards established by the
   American Institute of Certified Public Accountants. A review of interim
   financial information consists principally of applying analytical procedures
   to financial data, and making inquiries of persons responsible for financial
   and accounting matters. It is substantially less in scope than an audit
   conducted in accordance with generally accepted auditing standards, which
   will be performed for the full year with the objective of expressing an
   opinion regarding the financial statements taken as a whole. Accordingly we
   do not express such an opinion.

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

   We have previously audited, in accordance with generally accepted auditing
   standards, the consolidated balance sheet of STERIS Corporation and
   subsidiaries as of March 31, 1999 and the related consolidated statements of
   operations, shareholders' equity and cash flows for the year then ended, not
   presented herein, and in our report dated April 26, 1999, we expressed an
   unqualified opinion on those consolidated financial statements. In our
   opinion, the information set forth in the accompanying consolidated condensed
   balance sheet as of March 31, 1999, is fairly stated, in all material
   respects, in relation to the consolidated balance sheet from which it is
   derived.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
   RESULTS OF OPERATIONS

   RESULTS OF OPERATIONS

   Net revenue increased by 1.7% to $176.8 million in the first quarter fiscal
   2000 from $173.8 million in the first quarter fiscal 1999. Health Care Group
   revenues in the fiscal first quarter increased 0.3% from the prior year
   period to $131.1 million, or 74.2% of total Company revenues. Scientific and
   Industrial Group revenues were $45.7 million in the first quarter, an
   increase of 6.3% from the prior year period. Revenues from consumables and
   services were 58.0% of sales for the quarter, up from 56.4% in last year's
   first quarter.

   The costs of products and services sold increased by 2.5% to $94.8 million in
   the first quarter fiscal 2000 from $92.5 million in the first quarter fiscal
   1999. The cost of products and services sold as a percentage of net revenue
   was 53.6% for the first quarter fiscal 2000 compared to 53.2% for the same
   period in fiscal 1999. The increase in the cost of products and services sold
   as a percentage of net revenue in the first quarter fiscal 2000 reflected the
   addition of production facilities which were acquired as a result of business
   combinations.

   Selling, informational, and administrative expenses increased by 16.4% to
   $57.7 million in the first quarter fiscal 2000 from $49.5 million in the
   first quarter fiscal 1999. The increase in expenses reflected higher selling
   expenses as well as the addition of production facilities which were acquired
   as a result of business combinations. The expenses as a percentage of net
   revenue increased to 32.6% in the first quarter fiscal 2000 from 28.5% in the
   first quarter fiscal 1999.

   Research and development expenses increased by 3.0% to $6.2 million in the
   first quarter fiscal 2000 from $6.0 million in the first quarter fiscal 1999.

   Interest expense increased by 45.9% to $3.5 million in the first quarter
   fiscal 2000 from $2.4 million in the first quarter fiscal 1999. The increase
   was due to the additional borrowing under the Credit Facility principally for
   the purchase of acquired companies.

   Net income for the first quarter of fiscal 2000 decreased by 34.9% to $9.3
   million ($.14 per share) from $14.3 million ($.20 per share) in the same
   period fiscal 1999.

   LIQUIDITY AND CAPITAL RESOURCES

   The Company had $17.6 million in cash and cash equivalents as of June 30,
   1999, compared to $23.7 million of the same at March 31, 1999. The decrease
   was primarily attributable to the purchases of property, plant, and equipment
   and repurchase of common shares offset by cash received from borrowings, and
   the exercise of stock options.

   Accounts receivable decreased by 8.5% to $210.8 million as of June 30, 1999,
   compared to $230.3 million at March 31, 1999. The decrease reflected changes
   in revenues.

   Inventory increased by 22.8% to $122.0 million as of June 30, 1999, compared
   to $99.3 million at March 31, 1999. The increase in inventories during the
   period was due to an increase in costs to support product sales and
   anticipated future product sales.


                                       9
   10


   Prepaid expenses and other assets decreased by 12.9% to $15.8 million as of
   June 30, 1999, compared to $18.2 million at March 31, 1999.

   Property, plant, and equipment increased by 4.0% to $387.2 million as of June
   30, 1999, compared to $372.4 million at March 31, 1999. The increase was due
   to investments in informational technology systems, manufacturing equipment,
   and distribution systems.

   Intangibles decreased by 0.1% to $280.6 million as of June 30, 1999, compared
   to $280.8 million at March 31, 1999.

   Current liabilities decreased by 14.5% to $134.4 as of June 30, 1999,
   compared to $157.1 million at March 31, 1999.

   Long-term indebtedness increased by 15.8% to $256.5 million as of June 30,
   1999, compared to $221.5 at March 31, 1999. The increase was due primarily to
   fund the purchase of Common Shares.

   Other long-term liabilities were constant at $48.6 million as of June 30,
   1999 and March 31, 1999.

   On January 26, 1999, STERIS entered into a $400 million Credit Facility. The
   Credit Facility includes an unsecured revolver of $250 million which expires
   January 26, 2002. The remaining $150 million is an unsecured 364 day facility
   expiring on January 25, 2000, which can be extended annually for 364 days.
   The $400 million Credit Facility may be used for general corporate purposes
   and will bear interest at either KeyBank National Association's prime rate or
   at LIBOR plus a margin. The Credit Facility contains customary covenants
   which include maintenance of certain financial ratios. At June 30, 1999, the
   outstanding borrowings under the existing Credit Facility were $250 million.

   The Company has no material commitments for capital expenditures. The Company
   believes that its cash requirements will increase due to increased sales
   requiring more working capital, accelerated research and development, and
   potential acquisitions or investments in complementary businesses. However,
   the Company believes that its available cash, cash flow from operations, and
   sources of credit will be adequate to satisfy its capital needs for the
   foreseeable future.

   CONTINGENCIES

   For a discussion of contingencies, see Note G to the consolidated condensed
   financial statements.

   SEASONALITY

   Historical data indicates that financial results of acquired businesses were
   subject to recurring seasonal fluctuations. A number of factors have
   contributed to the seasonal patterns, including sales promotion and
   compensation programs, Customer buying patterns of capital equipment, and
   international business practices. Sales and profitability of certain of the
   acquired and consolidated product lines have historically been
   disproportionately weighted toward the latter part of each quarter and each
   fiscal year. Various changes in business practices resulting from the
   integration of acquired businesses into STERIS may alter the historical
   patterns of the previously independent businesses.

   YEAR 2000 DATE CONVERSION

   An issue affecting STERIS and most other companies is how computer systems
   and applications recognize and process date-sensitive information. Some older
   computer programs were written using two digits rather than four to define
   the applicable year. As a result, those computer programs have time-sensitive
   software that recognize a date using "00" as the year 1900 rather than the
   year 2000. Without corrective actions, this could cause a system failure or
   miscalculations causing disruptions of operations, including, among other
   things, a temporary inability to process transactions, send invoices, or
   engage in similar normal business activities.

   The Company has investigated the impact of the year 2000 issue on its
   products and does not anticipate any effect on the performance of its
   products. The Company is in the process of assessing and implementing
   necessary changes for all areas of the Company's business which could be
   impacted; these include such areas as business computer systems, technical
   infrastructure, plant floor equipment, building infrastructure, end-user
   computing, and suppliers. The Company has initiated a project to prepare its
   computer systems for the year 2000 and is addressing the year 2000 issues.

   The Company's year 2000 program activities include the identification of
   affected hardware and software, the development of a plan for remediating
   those systems in the most effective manner, the execution of that plan, which
   includes continuous testing, and the monitoring of the program's success.
   Although various locations are at differing stages of readiness with respect
   to the various focus areas, the identification and plan development phases of
   the project are substantially completed. The Company has completed the
   majority of the program, although certain applications will be completed
   throughout the second half of calendar 1999. Continuous review and testing
   are being conducted throughout all phases of the program to help ensure that
   compliance is achieved and maintained as the year 2000 approaches.

   The Company has implemented year 2000 compliant systems in a number of areas,
   including order entry systems. In a number of instances, the Company has
   replaced non-compliant systems with newer systems which will significantly
   improve functionality as well as appropriately interpret the calendar year
   2000 and beyond. Although the timing of these actions may have been
   influenced by the year 2000 issue, in virtually all instances they involved
   capital expenditures that would have occurred in the normal course of
   business. While the Company is implementing a year 2000 vendor compliance
   program, the Company has little direct control over whether its suppliers
   will make the appropriate modifications to their systems and applications on
   a timely basis.

   As part of the year 2000 program, contingency plans are being formalized as
   the target date for completion approaches. Business disruption scenarios are
   currently being identified and appropriate strategies are being evaluated in
   the development of these various plans. The Company is in the process of
   developing contingency plans (e.g., the selection of alternative suppliers)
   to address the potential business disruption scenarios that are being
   identified.

    Operating expenses include costs incurred in preparing systems and
    applications for the year 2000. The Company expects to incur internal staff
    costs as well as outside services (including consultants) and other expenses
    related to the conversion and testing of the systems and applications. These
    costs, which are expensed as incurred, have been immaterial to date. The

   year 2000 costs include internal modification and testing costs as well as
   costs associated with supply chain risk assessment and contingency planning.

   Based on assessments completed to date and compliance plans in process, the
   Company believes that it has an effective program in place to resolve the
   year 2000 challenges in a timely manner and the Company does not expect that
   the year 2000 issues will have a material effect on its business operations
   or results of operations. However, satisfactory completion of the program may
   not prevent business disruptions resulting from actions of critical suppliers
   and Customers. Such disruptions would impair the Company's ability to obtain
   necessary materials for production or sell products to Customers. If such
   disruptions occurred, the Company may experience lost or delayed sales and
   profits depending on the duration of the disruptions. Key aspects of the
   program are addressing potential uncertainties but the Company's ability to
   be fully confident of conditions related to third parties is limited.
   Currently, the Company cannot reasonably estimate the amount of potential
   lost or delayed sales and profits.

   EURO

   On January 1, 1999, eleven of the fifteen member countries of the European
   Monetary Union (EMU) began a three-year transition phase during which a
   common currency called the Euro was adopted as their legal currency. The Euro
   began trading on currency exchanges and is available for non-cash
   transactions. During the transition period, parties may pay for goods and
   services using either the Euro or the participating country's legacy currency
   on a "no compulsion, no prohibition" basis. The conversion rates between the
   existing legacy currencies and the Euro were fixed on January 1, 1999. The
   legacy currencies will remain legal tender for cash transactions between
   January 1, 1999, and January 1, 2002, at which time all legacy currencies
   will be withdrawn from circulation and the new Euro denominated bills and
   coins will be used for cash transactions.

   The Company has several operations within the eleven participating countries
   that will be utilizing the Euro as their local currency in 1999.
   Additionally, the Company's operations in other European countries and
   elsewhere in the world will be conducting business transactions with
   Customers and suppliers that will be denominated in the Euro. Euro
   denominated bank accounts have been established to accommodate Euro
   transactions. The Company's exposure to changes in foreign exchange rates may
   also be reduced as a result of the Euro conversion.

   The Company has established plans to review strategic and tactical areas
   arising from the Euro conversion. Over the past several periods, these plans
   have focused on aspects of the Euro conversion that required adjustment or
   compliance by January 1, 1999, and for conducting Euro-denominated business
   during 1999. These aspects included transacting business in the Euro, the
   competitive impact on product pricing, and adjustments to billing systems to
   handle parallel currencies. The Company has determined that these systems
   have the capability to handle Euro transactions and is currently in a
   position to transact business in Euros. Continuing analysis and development
   efforts will help ensure that the implementation of the Euro meets the
   timetable and regulations established by the EMU.

   Based on current estimates, the Company does not expect the costs incurred to
   address the Euro will have a material impact on its financial condition or
   results of operations.

   FORWARD-LOOKING INFORMATION

   This Form 10-Q contains statements concerning certain trends and other
   forward-looking information affecting or relating to the Company and its
   industry that are intended to qualify for the protections afforded
   "forward-looking statements" under the Private Securities Litigation Reform
   Act of 1995. There are many important factors that could cause actual results
   to differ materially from those in the forward-looking statements. Many of
   these important factors are outside STERIS's control. Changes in market
   conditions, including competitive factors and changes in government
   regulations, could cause actual results to differ materially from the
   Company's expectations. No assurance can be provided as to any future
   financial results. Other potentially negative factors that could cause
   actual results to differ materially from those in the forward-looking
   statements include (a) the possibility that the continuing integration of
   acquired businesses will take longer than anticipated, (b) the potential
   for increased pressure on pricing that leads to erosion in profit
   margins, (c) the possibility that market demand will not develop for new
   technologies, products, and applications, (d) the potential effects of
   fluctuations in foreign currencies where the Company does a sizable amount of
   business, and (e) the possibility of reduced demand, or reductions in the
   rate of growth in demand, for the Company's products.
