          Item 1.   Business.

          GENERAL

               Autoclave Engineers, Inc. (the "Company" or "Autoclave") was
          incorporated in Pennsylvania in 1958 and is the successor in
          interest, as the result of a merger, to Autoclave Engineers,
          Inc., an Illinois corporation founded in 1946.  From fiscal year
          1986 through fiscal year 1995, the Company consisted of three
          independent operating segments.  One segment was comprised of
          Burton Corblin, S.A., located in France, and Burton Corblin North
          America, Inc., located in the USA, collectively Burton Corblin. 
          Burton Corblin designed and manufactured high pressure diaphragm
          and piston compressors and associated equipment.  In January
          1995, the Company sold this segment.  Autoclave Products was the
          second business segment of the Company and was comprised of the
          Autoclave Engineers Group and the Autoclave Engineers Europe
          division, collectively Autoclave Engineers or AEG.  Autoclave
          Engineers designed, manufactured and marketed autoclaves,
          compressors, valves, fittings and related systems, components and
          accessories principally for elevated temperatures and/or pressure
          applications.  During the fourth quarter of fiscal 1995, the
          Company formalized a plan for the disposition of AEG.  On August
          14, 1995, the Company entered into an agreement to sell AEG to
          Snap-tite, Inc.  The third, and only remaining business segment
          of the Company, is the design and manufacture of mass flow
          controllers ("MFC's") through the Company's Unit Instruments,
          Inc. ("Unit") subsidiary.  MFC's are precision devices that
          control the flow of gases into wafer fabrication chambers that
          are integral in the manufacture of integrated circuits, commonly
          referred to as "ICs".

               Autoclave maintains its principal executive offices at 2930
          West 22nd Street, Erie, Pennsylvania 16506; but, intends to
          relocate these offices to the facilities occupied by Unit
          Instruments, Inc. in Yorba Linda, California.

          DISCONTINUED OPERATIONS

               In January, 1995 the Company sold Burton Corblin to James
          Howden & Godfrey Overseas Limited ("Howden") for $9.1 million and
          the forgiveness of certain debt.  A gain on this divestiture has
          been recorded in fiscal 1995 and the results of Burton Corblin's
          operations through the date of sale have been accounted for as
          income from discontinued operations.  The Company's Autoclave
          Engineers Europe ("AEE") division, which was located in certain
          facilities of Burton Corblin in France, was not part of the sale
          to Howden; but management concluded that without Burton Corblin's
          administrative support for AEE, the continued operation of AEE
          was not feasible.  The AEE operation has been restructured for
          sale; the cost of which has been charged against the results of
          AEG's operations for the year.

               Given the formalized plan for the disposition of AEG, this
          operation also has been treated as a discontinued operation for
          reporting purposes.  The assets and liabilities relating to AEG

                                         -4-
          have been classified on the balance sheet under the heading
          "Assets of Discontinued Operations Held for Sale".  In connection
          with the fourth quarter 1995 decision to dispose of AEG, the
          costs to restructure and dispose of AEE (previously included in
          the third quarter gain on the sale of Burton Corblin) were
          reclassified to AEG's results from discontinued operations. 
          Based upon the expected net proceeds from the pending sale of
          AEG, a gain on sale, net of tax, is expected to be recognized in
          the fiscal year ending May 31, 1996.  Operating results of AEG
          through the anticipated date of disposal are also expected to be
          positive.

               See Notes 1 and 2 of Notes to Consolidated Financial
          Statements included in Item 8 of this Form 10-K for additional
          information on these discontinued operations.
          PRODUCTS
               Unit designs and manufactures MFCs that are used to control
          the flow of gases in the fabrication of semiconductor wafers. 
          These wafers are produced in process chambers that require the
          introduction of various gases that are virtually contamination-
          free and are precisely controlled as to flow rate and volume. 
          Unit produces two primary families of MFCs; Elastomeric and All-
          Metal.  The All-Metal MFCs are typically used in more demanding
          process control environments and offer a higher level of
          contamination-free gas delivery.  MFCs represented over 85% of
          Unit's sales for fiscal years 1995, 1994 and 1993.

               Unit also produces a line of Pressure Controllers that
          control the pressure of gas as it enters the fabrication chamber,
          gas panels that integrate various flow components into a single
          panel and, a Digital Power Supply, trade name DX-5, that can
          control up to five Mass Flow Controllers or Meters.  The Company
          recently introduced a digital calibration device, SmartCable,
          that plugs-in to existing analog MFCs and provides for automatic
          calibration which improves gas delivery accuracy.  Unit services
          its customer base through four domestic service centers and
          generates additional revenue from this service activity.

               AEG has developed complete system capability with
          accompanying instrumentation, sub-systems and components for use
          in high pressure processes and research.  AEG's products include
          autoclaves, compressors, valves, fittings, tubing,
          instrumentation, controllers and related accessories.  AEG also
          manufactures sophisticated bench-top chemical reaction systems
          for process research.  AEG provides both standard products and
          specially engineered products for specific customer applications. 

               AEG participates in a 50/50 joint venture agreement with the
          Swedish multi-national firm, ASEA Brown Boveri.  The joint
          venture, called ABB Pressure Systems AB, located in Columbus,
          Ohio, markets worldwide hot and cold isostatic presses
          manufactured by either AEG's facility in Erie, or ASEA's Quintas
          Press Division in Sweden, depending upon the size and parameters
          of the particular press system.  The joint venture gives each
          party access to the other's technology while providing the
          financial strength that this continually advancing, leading-edge
          technology demands.

                                         -5-
          APPLICATIONS

               Unit's products are sold principally to semiconductor
          manufacturers.  Unit's technology has potential application in
          the petrochemical, fiber optic and other industries.

               AEG's products are used in research and critical production
          applications by a number of diverse industries, including the
          chemical, petrochemical, materials forming, energy, aerospace,
          defense and electronics industries.

          DISTRIBUTION AND MARKETING

               Unit distributes its products primarily through a direct
          sales and application engineering team of 24 representatives
          which is supplemented by several independent international
          distributors.  The Company actively employs several methods to
          market its products, including regular participation in trade
          shows, frequent advertisement in trade journals, submission of
          demonstration products to selected Original Equipment
          Manufacturers (OEMs) and end-users for evaluation and
          participation in prototype development efforts by major customers
          for "next" generation equipment.

               Unit sells approximately 75% of its product to OEMs and the
          balance to end-users.  OEM customers and potential customers
          include the world's leading manufacturers of semiconductor wafer
          processing equipment including Applied Materials, Lam Research,
          Tokyo Electron, Watkins-Johnson, Novellus and others.  End-user
          customers and potential customers include the world's leading
          manufacturers of semiconductors including Intel, Motorola, IBM,
          AMD, Samsung, Toshiba, and Siemens.

               For fiscal year 1995, Applied Materials accounted for 37% of
          the continuing Company's net sales and Lam Research accounted for
          18% of net sales.

               Approximately 10%, 10% and 14% of the Unit's net sales were
          exported from the United States in fiscal 1995, 1994 and 1993,
          respectively.

               AEG's marketing activities in the United States and Canada
          are handled by an employee field staff, the majority of whom are
          sales engineers, operating out of its Erie location, a direct
          sales office located in Texas and one sales office in Canada. 
          AEG also uses domestic independent sales agents and independent
          distributors.  Sales in foreign countries are presently handled
          by one direct sales office in France and by independent sales
          agents and independent distributors.  The field sales activities
          are supported by an administrative staff in Erie, Pennsylvania
          including application engineers.  AEG also markets certain of its
          products domestically and abroad through manufacturers'
          representatives.

               AEG maintains distribution warehouses for standard valves
          and fittings in Houston, Texas and Burlington, Canada.  

                                         -6-
               The Company's standard warranty on its products covers
          repair and replacement of defective products for a period of one
          year from the date of shipment.  The Company employs full-time
          field service personnel to provide repair, maintenance and
          warranty services for domestic and foreign customers.

          BACKLOG

               The Company's backlog for continuing operations at May 31,
          1995 was approximately $3.3 million, compared to backlog at May
          31, 1994 of approximately $2.4 million,  General industry
          practice allows for orders to be rescheduled or canceled without
          significant penalty.  Most customer orders in backlog are
          deliverable within one to four weeks and, accordingly, the
          Company's backlog at any given date is not necessarily indicative
          of actual sales for any succeeding period.

          INVENTORY AND WORKING CAPITAL

               Unit is required to carry significant amounts of inventory
          to meet the rapid delivery requirements of its customers and to
          buffer against extended leadtimes for certain raw materials.  The
          Company does not provide extended payment terms to its domestic
          customers, but does selectively extend payments terms to certain
          international customers.  Returns for customer convenience are
          not allowed by the Company.

          PRODUCT DEVELOPMENT

               Unit is a leader in the development of mass flow controllers
          and peripheral accessories.  The Company commits substantial
          resources toward enhancing existing products and developing new
          products that establish industry standards for performance,
          reliability and pricing.

               For fiscal 1995, 1994 and 1993, Unit spent $1,874,000,
          $1,067,000 and $762,000, respectively, for research and
          development activities.

          INTELLECTUAL PROPERTY

               The Company has a policy to aggressively seek patents on new
          products and improvements when appropriate.  Unit currently holds
          14 U.S. patents and has applied for 6 additional U.S. patents. 
          In addition, Unit has 8 foreign patents and 14 pending
          applications.  Although the Company believes its patents have
          value and could potentially provide a competitive advantage, it
          believes the success of the business depends on innovation,
          technical expertise and know-how of its personnel, along with
          other factors.

                                    -7-
          COMPETITION
               The market for Unit's mass flow controllers is highly
          competitive.  Significant competitive factors include product
          quality, performance and capabilities, price, delivery leadtimes,
          customer service and support, breadth of product offering, size
          of installed base and historical relationship with the customer. 
          The Company believes that it competes favorably with respect to
          these competitive factors, with the primary exception of being
          predominantly a one-product supplier, i.e. mass flow controllers.
          Unit has three major domestic competitors and two Japanese
          competitors.  Unit has a small manufacturing facility in Japan to
          support and augment its efforts to penetrate the Japanese market;
          and while some market share penetration has occurred, it is still
          limited.  For Unit to maintain and enhance its competitive
          position, significant investments in engineering, manufacturing
          process improvements, marketing, customer service and support
          will be required in the future.
           
               Although AEG is not aware of any other single company which
          markets its full line of products, AEG's business is subject to
          intense competition.  Many of AEG's competitors (including
          customers who may elect to manufacture high pressure systems or
          catalytic reaction systems for internal use) have financial,
          marketing and other resources greater than those of AEG.  There
          are a number of companies that specialize in a limited number of
          the products manufactured by AEG.

               The most significant competitive factors with respect to
          AEG's products are technical performance, quality control and the
          engineering and sales service support experience of its
          personnel.  Certain products sold by AEG's competitors are less
          expensive than comparable products sold by AEG, thereby
          subjecting these products to intense price competition.

          MANUFACTURING AND SUPPLIERS

               Unit designs, manufactures and assembles precision
          components at its own facilities but also relies on third-party
          suppliers for various machined parts and subassemblies.  All
          final assembly activity is performed in cleanrooms.  Unit has
          three manufacturing facilities:  the main facility in Yorba
          Linda, California; and two smaller facilities in Japan and
          Ireland.  Customers are increasingly seeking reductions in
          leadtimes, increases in quality and higher price/performance
          levels.  To meet and exceed customer expectations, several
          manufacturing strategies have been implemented, including TQM and
          team benchmarking.  The Company is in the process of implementing
          ISO 9001 certification for its Yorba Linda facility and expects
          this to be accomplished during fiscal year 1996.

                                         -8-
               Most materials used in Unit's products are standard items
          that are available from multiple sources.  However, certain
          machined parts and raw materials are obtained from a single
          source or a limited number of suppliers.  In addition, selected
          raw materials have an extended leadtime. Although the Company
          seeks to limit its dependency on sole or limited source suppliers
          and to reduce leadtimes for raw materials, the partial or
          complete loss of these suppliers or an abrupt change in leadtimes
          for raw material could have a material adverse effect on the
          Company's results of operations.
               The principal material used by AEG in manufacturing
          autoclaves, valves, fittings and related parts and equipment is
          stainless steel, which is purchased in a variety of shapes and is
          produced by AEG's raw materials suppliers in accordance with
          rigid chemical and physical specifications established by AEG. 
          AEG purchases other metals such as inconel, nickel, monel,
          hastelloy and titanium that are used in the production of
          autoclaves.  AEG also purchases forgings, magnets, pumps,
          compressors, controls and instruments. 
               AEG has not experienced and does not foresee any
          availability problems with respect to components of such products
          beyond periodic shortages created by changing economic
          conditions.

          REGULATION
               In the U.S.A., most states require high pressure systems to
          comply with specifications established by the American Society of
          Mechanical Engineers Code ("ASME Code"), which provides technical
          guidelines for designing, manufacturing and quality control of
          the systems.  Some states have additional safety code
          requirements for high pressure systems.  Equipment used in
          commercial nuclear facilities is subject to quality control and
          quality assurance procedures established by the Nuclear
          Regulatory Commission.  Foreign governments regulate the sale,
          installation and use of high pressure systems in their
          jurisdictions and many of their regulations vary from the ASME
          Code.  The Corporation believes it has obtained all applicable
          regulatory approvals for its products.

          ENVIRONMENTAL COMPLIANCE
               The Company's facilities are subject to federal, state and
          local environmental control regulations.  To date, compliance
          with environmental regulations has not had a material effect on
          the Company's earnings nor has it required the Company to expend
          significant capital expenditures.  See Note 12D of Notes to
          Consolidated Financial Statements.

          INSURANCE
               Because some of the products of AEG are subject to extreme
          pressures and temperatures, there are potential exposures to
          personal injury as well as property damage, particularly if
          operated without regard to the design limits of the systems and
          components.  

                                      -9-
               AEG endeavors to minimize its product liability exposure and
          insurance costs by engineering safety devices for its products,
          carefully monitoring incidents involving its products to
          determine areas where safety improvements may be made, and
          encouraging its customers to carry out necessary maintenance and
          training programs in connection with its products.  Although the
          Company believes that it maintains adequate product liability
          insurance coverage obtained through various insurance companies,
          there is no assurance that its coverage will be sufficient to
          cover future claims against the Company.

          EMPLOYEES

               As of May 31, 1995, Unit had a total of 365 full-time and
          temporary employees, of which 294 were in manufacturing and
          service support, 24 in marketing, sales and applications
          engineering, 24 in product development, and 23 in finance and
          administration.  In addition, the Company had 181 employees in
          its Autoclave Engineers Group.  All current employees of AEG will
          be offered employment by the proposed purchaser of AEG, with the
          exception of approximately 6 employees involved primarily in
          corporate administrative functions.  None of the Company's
          employees are represented by a union or other collective
          bargaining group, and the Company considers its relationship with
          its employees to be good.

          EXECUTIVE OFFICERS OF THE COMPANY

               The following table sets forth the names of all executive

               Dr. Schilling joined AEG in June 1989 as assistant to the
          President of AEG.  He became Executive Vice President of AEG in
          April 1990 and was named President of AEG, effective June 1,
          1991.  On April 30, 1992, he was named President and Chief

          since that date as Unit's President and Chief Executive Officer.

               Mr. Guelcher joined the Company in 1989.  Prior to that he
          held various managerial positions during his 23 years of service
          at International Paper, formerly Hammermill Paper Co., the last
          being Treasurer.

               Mr. Sontag has been Treasurer since 1982, Secretary since
          1985 and Corporate Controller since 1989.

                                      *   *   *

               Each officer holds office until his successor is elected or
          until his death, resignation or removal.

               Mr. Levinson is the husband of Marilyn G. Levinson, a
          director of the Company.  There are no other family relationships
          between any officers and directors.

          Item 2 - Properties

               Unit leases an 80,000 square foot facility in Yorba Linda,
          California for manufacturing and support activities.  This lease
          expires in 2001 but provides for renewal options.  Unit owns a
          4,000 square foot manufacturing facility in Dublin, Ireland;
          leases a 2,850 square foot manufacturing facility in Tokyo,
          Japan; and has four leased service centers in San Jose,
          California; Tempe, Arizona; Dallas and Austin, Texas.

               The Company owns a 60,000 square foot building in Erie,
          Pennsylvania and also owns, or leases under a long-term capital
          lease from the Erie County Industrial Development Authority,
          other contiguous buildings with approximately 40,000 square feet. 
          The lease with Erie County Industrial Development Authority
          expires in 1998.  Under terms of this lease, the Company has the
          right to purchase for a nominal sum the property to which this
          lease is related at the lease expiration date.  The Company also
          owns a 12,000 square foot facility in Oxford, Pennsylvania that
          is being leased to a third party.  The Company will transfer its
          interest in the above property to the buyer of AEG.

               The Company's domestic manufacturing operations are being
          utilized generally on one full shift and partial second and third
          shifts, while the foreign operations operate on a single shift. 
          Management believes that the Company's existing facilities will
          be adequate for its immediate needs.




                                         -11-


          Item 3.   Legal Proceedings.

               Unit is not a party to any claims or legal proceedings.

               AEG is involved in a number of claims and legal proceedings
          of a nature considered normal to its business, principally
          product liability matters.  Certain of these cases seek damages
          which, if awarded, would require sizeable payments.  While it is
          not feasible to predict the outcome of these actions
          with certainty, management of the Company, based upon available
          information, believes that any liability that may arise from
          these proceedings will not have a material adverse effect on the
          consolidated financial condition or projected results of
          operations of the Company.

          Item 4.   Submission of Matters to a Vote of Security Holders.

               During the fourth quarter of the fiscal year covered by this
          report, no matter was submitted to a vote of security holders of
          the Company.

          During fiscal 1993, the Company changed its method of valuing
          certain inventories from the last-in, first-out method to the
          first-in, first-out method.  The selected financial data for the
          fiscal years 1991 and 1992 have been restated to reflect this
          change in accounting principle.  The impact on net earnings for
          each of the restated years was:  a decrease of $235,000, or $.06
          per share in 1992 and a decrease of $460,000, or $.11 per share
          in 1991.

                                         -14-
          In fiscal 1994, the Company changed the method of accounting for
          overhead costs in certain inventories.  Prior to 1994, costs
          related to material processing and handling activities were
          applied to production as a function of direct labor incurred;
          however, effective in 1994, they were applied based on their
          relationship to material costs incurred.  The cumulative effect
          of adopting this change as of June 1, 1993 is included in the net
          income and net income per share for the fiscal year ended May 31,
          1994.  Prior years' financial data have not been restated.

          1995 Compared to 1994

               Sales from continuing operations increased 46% to $48,256
          for fiscal year 1995 reflecting, in part, the continuation of the
          strong upturn in the semiconductor equipment market that began in
          1993.  The Company introduced two new metal seal mass flow
          controller ("MFC") models in fiscal 1994 that gained excellent
          market acceptance during the current fiscal year.  These new
          products accounted for the majority of the sales increase for the
          year.  In addition, average selling prices were generally higher
          for the current fiscal period as compared to the prior year
          period.  The Company's older model MFCs recorded lower unit sales
          for the year but favorable mix and high average selling prices

                                         -15-

          resulting in stable revenue for the current period.  Sales from
          the Company's offshore operations were also stable for the fiscal
          year.

               Cost of sales, as a percent of sales, decreased slightly to
          64% from the prior year's 65%.  This decrease was attributable to
          marginally lower overhead, as a percent of sales, at the
          Company's main manufacturing facility in Yorba Linda, California
          because of significantly higher volume levels.  This improvement
          was partially offset by higher expenses at the Company's facility
          in Japan.

               Selling and administration expenses and restructuring costs
          increased $4,564 or 46% over the prior fiscal year.  Unit
          recorded higher expenses because of increased volume levels but
          these expenses, as a percent of sales, decreased over the prior
          year period.  These expenses were $1,841 higher for the fiscal
          year because of certain expenses associated with the
          restructuring of the Company's corporate office activities,
          including $1,230 in severance and related costs recorded in the
          fourth quarter of 1995, which are expected to be paid in the
          second quarter of 1996.  The Company anticipates that corporate
          expenses will decrease in the subsequent fiscal year as Unit
          assumes these functions and certain cost savings are realized.  

               Research and development expenses increased 75% over the
          prior year and increased as a percent of sales to 3.9% in fiscal
          1995 from 3.2% for fiscal 1994.  These higher expenses represent
          additional staffing and increased development activity directed
          toward product enhancements and new products.

               Interest income increased to $230 in 1995 compared to $66 in
          1994.  The increase in interest income was attributable to higher
          cash balances generated from the sale of Burton Corblin in 1995
          which were offset, to a limited extent, by generally lower
          interest rates.  Interest expense decreased to $339 from $448
          because of lower average borrowings outstanding and lower
          interest rates on these borrowings.

               The effective rate for income tax provided in 1995 was
          approximately 25% compared to a 199% rate in the prior year.   
          The prior year rate was adversely impacted because of low pre-tax
          income, the inclusion, for tax purposes, of nondeductible foreign
          losses and other expense items, including goodwill and business
          meal expenses, the adjustment of prior accruals, and the adoption
          of Statement of Financial Accounting Standards (SFAS) No. 109 -
          Accounting for Income Taxes.

               Effective June 1, 1993, the Company adopted prospectively
          SFAS No. 109.  This Statement required the Company to change its
          method of accounting for income taxes from the deferred method to



                                         -16-

          the liability method which requires the recognition of deferred
          tax assets and liabilities for the estimated future taxes payable

          or recoverable, arising from temporary differences between the
          tax bases of assets and liabilities and their financial statement
          bases.  The effect of adopting SFAS No. 109 was an increase to
          the provision for income tax on continuing operations of
          approximately $162  and a decrease on discontinued operations of
          $25.

               The Company's results of operations may be affected in the
          future by a variety of factors including:  the dependency of
          sales on a few large customers, product mix, new product
          introductions by the Company and the Company's competitors,
          operating expenses and the scheduling of orders by customers.  In
          addition, the Company's results could be affected by demand for 
          semiconductor equipment, which has experienced strong growth the
          past two years, and technology changes in the market.

               During the third quarter of fiscal 1995, the Company sold
          its compressor operations in the United States and France and
          recorded a gain on disposal of this business segment.  During the
          fourth quarter, the Company recorded additional reserves for this
          discontinued operation.  Under the terms of the sale agreement,
          the Company has retained certain known product warranty exposures
          and has provided a commitment for the realization of purchased
          assets, primarily accounts receivable.  The current estimate of
          these costs is $225,000 which has been provided for in 1995. 
          Approximately $365,000 of the proceeds from the sale remain in
          escrow until settlement or realization of these contingencies.

               In the fourth quarter of fiscal 1995, the Company developed
          a plan for the disposition of its Autoclave Engineers Group
          ("AEG") business segment.  Accordingly, this operation has been
          accounted for as a discontinued operation for year-end reporting
          purposes.  A definitive agreement for sale has since been
          executed, and based upon management's estimation of net proceeds
          from the sale of AEG and associated costs relating to this sale,
          a gain on disposal is probable and will be recorded when
          realized, expected to be during the second quarter of fiscal
          1996.

          1994 Compared to 1993

               Sales from continuing operations increased 38% to $33,141
          for fiscal year 1994 as compared to the prior year's sales of
          $23,965.  Sales of MFCs were favorably impacted by a strong
          upturn in the semiconductor equipment market and the introduction
          of two new metal seal MFC models that received good market
          acceptance.  Sales into the Japanese market recovered modestly 


                                         -17-

          over the prior year because of increased activity in the
          semiconductor market as did sales into the European market
          through the Company's subsidiary in Ireland.

               Cost of sales, as a percent of sales, decreased to 65% from
          the prior year's 68%.  This decrease in cost of sales resulted
          from several factors:  the absorption of fixed overhead costs at
          the Company's main manufacturing facility in Yorba Linda over
          significantly higher sales volume; increases in manufacturing
          efficiencies; and, the favorable impact of new pricing 

          arrangements on certain long-term contracts.  Lower cost of sales
          at the Company's facility in Japan also contributed to the
          overall improvement in the current fiscal year.

               Selling and administration expenses increased $705 or 8%
          over fiscal year 1993 but declined dramatically, as a percent of
          sales, to 30% from almost 39% the prior year.  Unit recorded
          higher expenses for sales commissions and sales support
          activities because of higher sales levels while Corporate
          expenses declined marginally, reflecting the impact of tight
          expense controls.

               Research and development expenses increased 40% over the
          prior year but remained constant, as a percent of sales, at 3.2%. 
          These higher expenses were directed toward a new model
          development, product enhancements and continued work on advanced
          sensor technology.

               Interest income declined compared to the prior year because
          of lower interest rates and a decrease in average cash balances
          available for investment.  Interest expense rose slightly because
          of higher average borrowings outstanding during the fiscal year. 
          Other income dropped for the fiscal year to $70 from $563 the
          prior year because of lower foreign currency exchange gains and
          the recording, in fiscal 1993, of a $263 pre-tax gain on the sale
          of stock in Autoclave Toll Services Limited.

               Income taxes were provided for at a 199% rate in 1994 as
          compared to 21% benefit in fiscal 1993.  The 1994 rate was
          adversely impacted by the factors previously mentioned.  See Note
          7 of Notes to Consolidated Financial Statements for a
          reconciliation of the effective tax rate for each fiscal year to
          the normal federal statutory rate of 34%.

          Liquidity and Capital Resources

               Cash and short-term investments increased by $3,648 to
          $9,384 at May 31, 1995.  During the third quarter, the Company
          sold its Burton Corblin subsidiary and received cash proceeds of
          $8,312.  Accounts receivable and inventory balances at Unit
          increased approximately $4.6 million during the year in support
          of rapidly increasing sales.  This trend is expected to continue
          during fiscal 1996.

               Unit's capital expenditures were approximately $2.8 million
          in the current fiscal year and are projected to be in the four to
          five million dollar range over the next several years.  These
          expenditures are primarily required to augment manufacturing
          capacities and capabilities in the production of MFCs.  At May
          31, 1995, the Company was not committed to any significant plant
          or equipment contracts except $850 for construction of an
          additional clean room at the Yorba Linda, California facility.

               For fiscal 1995, research and development expenditures
          totaled $1,874 which was a 76% increase over the prior year.  The
          Company anticipates that research and development charges will
          increase by approximately 50% in the coming fiscal year and will
          remain at a relatively high level for the foreseeable future.

               In addition to the $9,384 cash and cash equivalents balances
          at year-end, the Company had approximately $5.7 million available
          under domestic credit facilities at May 31, 1995.  In addition,
          the Company expects to realize approximately $13 million in cash
          from the sale of AEG during the second fiscal quarter of 1996. 
          The Company believes that these cash resources are adequate to
          meet its near-term financing needs.

                          Report of Independent Accountants




          To the Shareholders and the
          Board of Directors of Autoclave Engineers, Inc.


          In our opinion, the consolidated financial statements listed in
          the accompanying index appearing under item 14(a) 1 and 2 on page
          56 present fairly, in all material respects, the financial
          position of Autoclave Engineers, Inc. and its subsidiaries at May
          31, 1995 and 1994, and the results of their operations and their
          cash flows for each of the three years in the period ended May
          31, 1995, in conformity with generally accepted accounting
          principles.  These financial statements are the responsibility of
          the Company's management;  our responsibility is to express an
          opinion on these financial statements based on our audits.  We
          conducted our audits of these statements in accordance with
          generally accepted auditing standards which require that we plan
          and perform the audit to obtain reasonable assurance about
          whether the financial statements are free of material
          misstatement.  An audit includes examining, on a test basis,
          evidence supporting the amounts and disclosures in the financial
          statements, assessing the accounting principles used and
          significant estimates made by management, and evaluating the
          overall financial statement presentation.  We believe that our
          audits provide a reasonable basis for the opinion expressed
          above.  

          As discussed in Note 4 to these Consolidated Financial
          Statements, the Company changed its method of accounting for
          overhead costs in certain inventories in fiscal 1994.

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
          (amounts in thousands, except share data)


          1.   SIGNIFICANT ACCOUNTING POLICIES

               The following is a summary of the significant accounting
          policies followed by the Company in the preparation of the
          accompanying consolidated financial statements.

          PRINCIPLES OF CONSOLIDATION

               The consolidated financial statements include the accounts
          of Autoclave Engineers, Inc. and its subsidiaries (the Company). 
          The fiscal year for the Company is a twelve-month year ending on
          May 31.  

               The Company sold its Burton Corblin operations in January
          1995 and has developed a plan to sell the Autoclave Engineers
          Group (AEG).  Both of these operations have been accounted for as
          discontinued operations in the accompanying financial statements. 
          The Consolidated Statement of Income reflects the results from
          the continuing operations of Unit Instruments, Inc. and its
          subsidiaries and corporate activities while the results of the
          discontinued operations have been segregated and shown separately
          for all years presented.  The net assets of AEG including related
          deferred taxes have been classified as a single line item on the
          Balance Sheet at May 31, 1995.  Prior years' information for
          discontinued operations on the Consolidated Balance Sheet and
          Consolidated Statement of Cash Flow has not been reclassified or
          restated.  

               The Company has a 50% interest in ABB Pressure Systems AB
          and had a one third interest in a corporate joint venture in
          Germany, both accounted for on the equity method.  The interest
          in the German joint venture was terminated as of June 30, 1994,
          with an immaterial effect.

               All material intercompany accounts and transactions are
          eliminated in consolidation.

          CASH AND CASH EQUIVALENTS

               The Company's policy is to include cash and all time
          deposits and marketable securities with an initial maturity of
          three months or less in cash and cash equivalents.

          INVENTORY VALUATION 

               Inventories are carried at the lower of cost or market with
          cost being determined on the first-in, first-out method.  




                                         -28-

          1.   SIGNIFICANT ACCOUNTING POLICIES (continued)

          PROPERTY, PLANT AND EQUIPMENT

               The Company computes depreciation for financial statement
          purposes principally on the straight-line method.  

               Repairs and maintenance are charged to expense as incurred. 
          Major renewals and betterments are capitalized.  The cost of
          property, plant or equipment replaced, retired, or otherwise
          disposed of and the related accumulated depreciation are
          eliminated from the accounts.  Any resulting gain or loss, after
          giving effect to salvage and removal costs, is added to or
          deducted from income.

          GOODWILL

               Goodwill relates to continuing operations and is amortized
          on a straght line basis over a period of forty years from the
          date of the related business combination.

          REVENUE RECOGNITION

               The Company recognizes income principally on the completed
          contract basis.

          EARNINGS PER SHARE

               Earnings per share is computed using the average number of
          shares outstanding during each period plus common share
          equivalents which would arise from the exercise of stock options
          and stock warrants
          .  
          PRODUCT WARRANTY COSTS

               The Company expenses product warranty costs principally when
          incurred; however, prospective product warranty costs on
          significant contracts are provided for at the time management
          determines that such costs are likely to be incurred and can be
          reasonably estimated.

          2.   DISCONTINUED OPERATIONS

               On January 19, 1995, the Company sold its Burton Corblin
          compressor operations in the United States and France to James
          Howden & Godfrey Overseas Limited (Howden) for a cash sales price
          of $9,064 and the forgiveness of $2,584 in debt owed by Autoclave
          Engineers, Inc. to Burton Corblin, S.A. (BCSA).  Howden did not
          acquire control of Autoclave Engineers Europe (AEE) which was
          owned by BCSA and operated out of the BCSA facility in France;
          however, interdivisional debt of $3,122, owed by AEE to BCSA was
          forgiven.  The transaction resulted in an after tax gain of $963
          after provision for certain estimated costs.

                                         -29-
          2.   DISCONTINUED OPERATIONS (continued)
               In May 1995, the Board of Directors of the Company developed
          a plan to dispose of the Autoclave Engineers Group (AEG) or
          Autoclave Products business segment.  This segment also has been
          treated as a discontinued operation at May 31, 1995.  Based on
          the terms of a definitive agreement subsequently reached with a
          prospective buyer of AEG, a net gain is expected to be realized
          on this transaction and recognized in the second quarter of
          fiscal 1996.

               The net assets of AEG and related deferred taxes have been
          classified as a single line on the May 31, 1995 Consolidated
          Balance Sheet as "Assets of Discontinued Operations Held for
          Sale".  The composition of these net assets was:

               Current assets                      $ 9,970
               Property, plant & equipment, net      3,588
               Other assets                          1,710
               Current liabilities                 ( 3,534)
               Other liabilities                   (    74)
               Deferred taxes                      (   588)
                                                   --------
                                                   $11,072
                                                   =======
                                            
               The results of operations of Burton Corblin and AEG have
          been reported as discontinued operations in the accompanying
          Consolidated Statement of Income for all three years presented
          theron.  The net sales and net income for the discontinued
          operations for the years ended May 31, 1995 is presented below:

                                         1995      1994      1993
                                        ______    ______    ______
               Net sales:
                 AEG                    $28,683   $26,887   $31,308
                 Burton Corblin          19,792    19,878    21,995

               Net income:
                 AEG                        753        88       444
                 Burton Corblin             581     1,098     1,271

               With the disposition of Burton Corblin and AEG, the
          continuing operations of the Company represent a single business
          segment for Mass Flow Control Equipment.  The identifiable assets
          of the discontinued segments at May 31, 1994 and 1993 were:

                                                   1994       1993
                                                  ______     ______
               Autoclave Products (primarily US)  $24,328   $23,784
               Compressors (primarily France)      23,978    28,175

          As the administrative and management support of AEE was
          previously provided by BCSA, the Company determined that the
          continued operation of AEE without this support was not feasible
          and began a plan to restructure AEE for ultimate sale.  Included
          in the net income of AEG presented above was an after tax charge
          of $494 for the estimated cost of this restructuring effort.   




                                         -30-
          2.   DISCONTINUED OPERATIONS (continued)
              Related to the above divesting activity, the Company
          established a plan to restructure the Corporate office function
          currently located in Erie, Pennsylvania and relocate it within
          Unit in Yorba Linda, California.  Virtually all of the $1,230
          fourth quarter 1995 restructuring costs relate to severance
          benefits for six corporate officers and staff.  Payment of these
          benefits is anticipated to occur in fiscal 1996.

          3. SHORT-TERM INVESTMENTS

              Short-term investments at May 31, 1995 and 1994 consisted of
          the following:

                                  May 31, 1995             May 31, 1994

                              $5,013  $4,919  $4,980     --     $17  $17
                              ======  ======  ======    ===     ===  ===

               The municipal bonds and money market account are interest
          bearing at various rates of interest.  Commercial paper is
          acquired at a discount with rates averaging 6.25%.

          4.   INVENTORIES
               Inventories at May 31, 1995 and 1994 consisted of the
          following:
                                                     1995      1994

               Raw materials                      $ 5,326   $ 3,142
               Work in process                      1,896     2,056
               Finished goods                       1,218     1,276
               Inventory of discontinued
                 operations                            --     7,844
                                                  -------   -------
                                                  $ 8,440   $14,318
                                                  =======   ======= 
               In the fourth quarter of 1994, the Company changed the
          method of accounting for overhead costs in certain inventories. 
          These costs related to material processing and handling
          activities which, prior to 1994, were applied to production as a
          function of direct labor incurred.  The Company believes that the
          more appropriate method of applying the costs of these material-
          support activities is based on their relationship to material
          costs incurred.

                                         -31-
          4.   INVENTORIES (continued)
               The cumulative effect of adopting this change as of June 1,
          1993 is shown in the Consolidated Statement of Income for the
          year ended May 31, 1994.  Prior years' financial statements have
          not been restated.  The Company has determined that the pro forma
          effect of restating the consolidated results of operations for
          the fiscal year ended May 31, 1993 would have increased net
          income by $90 and net income per share by $0.02.

          5.   BANK LINES OF CREDIT

               At May 31, 1995, the Company had arrangements at two
          domestic banks for unsecured lines of credit totalling $8,450, of
          which $250 is specifically in support of any foreign exchange
          contracts entered into by the Company with one of the bank's
          affiliates.  The lines provide for interest at the banks' prime
          rates.  The unused portion of these lines of credit, after
          deducting letters of credit supported by the lines, was $5,690 at
          May 31, 1995.

          6.  TERM DEBT

              As of May 31, 1995 and 1994, term debt consisted of the
          following:
                                                        1995          1994 
          Capital lease obligations at interest 
           rates approximating 7.25% at May 31, 
           1995, due from 1995 through 1999 (a)      $  100         $  141 
          Term loan (b)                                 812          1,201 
          Other bank notes payable (c)                2,697            313 
                                                     ------      ------
          Total term debt                             3,609          1,655 
          Less current installments                  (3,156)          (703)
                                                     -------        -------
                                                     $  453         $  952 
                                                      ======        =======

          (a) The Company has capitalized the leases of its manufacturing
          facilities which were acquired with the proceeds from industrial
          revenue bonds.    


              The assets recorded under these capital leases are
          depreciated as company-owned facilities and are included in
          property, plant and equipment at May 31, 1995 and 1994 as
          follows:

          6.  TERM DEBT (continued)

          (b) The Company has a Loan Agreement (the Agreement) with PNC
          Bank N.A. under which the Company borrowed two unsecured loans
          with interest rate options for five and seven years.  At the end
          of the initial term of a loan, the interest rate can be
          reestablished for another fixed period.  The initial term plus
          the renewal period cannot exceed ten years.  Various interest
          alternatives are available under the agreement.  The Company has
          the option of prepaying a loan at the end of any fixed term.  At
          May 31, 1995, the loans bear interest at 8.5% and 9.5%. Payments
          are due in monthly installments of $40, including interest, 
          through 1997.

               The Company is required to comply with certain restrictive
          covenants under the Agreement.  The most significant of these
          covenants are:  to maintain consolidated net worth as defined in
          the Agreement of not less than $15,000; to maintain a ratio of
          total liabilities to consolidated tangible net worth not to
          exceed 1.5 to 1; to maintain working capital of at least $3,000;
          to not pay dividends in excess of $1,100 in any year (subject to
          renegotiation in the event of additional issuance of stock); to
          not incur additional term indebtedness in excess of $1,000 in any
          one year; and to not incur capital expenditures in excess of
          $7,000 in any one year.  The above restrictive covenants can be
          waived by the bank at any time if deemed appropriate by the bank.

          (c) The Company has two loans with foreign banks to provide
          working capital to its subsidiary in Japan.  The loans have 
          annual maturities and bear interest at 3 1/2%.  Both loans are
          secured by letters of credit drawn against one of the Company's
          domestic bank lines of credit.

              The following is a schedule by year of principal payments,
          excluding interest, as of May 31, 1995:

          Temporary differences, arising from continuing operations,
          between the financial bases and tax bases of assets and
          liabilities result in deferred income taxes.  The types of
          temporary differences that gave rise to a significant portion of
          the deferred tax assets and liabilities in the Corporation's
          balance sheet at May 31, 1995 and 1994 were:

          A valuation allowance of $450 has been continued against deferred
          tax assets related to the utilization of foreign tax credits; a
          valuation allowance of $105 has been established for state
          operating loss carryforwards unusable after AEG is discontinued.

          At May 31, 1995, the Company had foreign tax credit carryforwards
          available for federal income tax purposes, operating loss
          carryforwards attributable to certain of its foreign subsidiaries
          and state loss carryforwards.  The amount of these carryforwards
          and the year in which they expire are:

          7.  INCOME TAXES (continued)

          Income from continuing operations before income taxes (and before
          allocation of general corporate expenses) derived from foreign
          subsidiaries was $277, $33 and $41 for the years ended May 31,
          1995, 1994 and 1993, respectively.

          The cumulative amount of unrepatriated earnings, of continuing
          foreign subsidiaries and entities owned 20% or more, for which no
          deferred taxes have been provided is $1,361 at May 31, 1995.  It
          is the Company's intention to reinvest undistributed earnings of
          certain of its foreign subsidiaries and thereby indefinitely
          postpone their remittance.

          Effective June 1, 1993, the Company adopted prospectively
          Statement of Financial Accounting Standards (SFAS) No. 109,
          "Accounting for Income Taxes".  This Statement required the
          Company to change its method of accounting for income taxes from
          the deferred method to the liability method which requires the
          recognition of deferred tax assets and liabilities for the
          estimated future taxes payable or recoverable, arising from
          temporary differences between the tax bases of assets and
          liabilities and their financial statement bases.  Prior to fiscal
          1994, accounting for income taxes was determined under the
          provisions of Accounting Principles Board Opinion No. 11.

          The effect of adopting SFAS No. 109 increased the provision for
          income tax for continuing operations in fiscal 1994 by
          approximately $162 and reduced the provision for income tax for
          discontinued operations by $25.  The consolidated financial
          statements for the periods prior to fiscal 1994 have not been
          restated.  This accounting change would not have had a material
          effect on the Company's net income for fiscal 1993.


          8.  RETIREMENT AND PROFIT SHARING PLANS

          The Company has maintained a contributory, defined benefit plan
          covering substantially all employees of AEG and corporate
          employees, who meet certain age and length of service
          requirements.  As a condition of participation, employees have
          been required to contribute 3% of their salaries to the plan for
          a maximum of thirty years.  The Company's funding policy has been
          to make annual contributions to the plan in amounts determined by
          enrolled actuaries which, when combined with employees'
          contributions, will provide the defined level of benefits at
          retirement.  These benefits are based on the average of total
          compensation for certain specified months of service prior to
          retirement.

          The employees of Burton Corblin, S.A. particpated in an unfunded,
          retirement indemnity plan as required by French law.

          Unit maintains a qualified profit sharing (401K) plan for
          substantially all of its employees who meet certain age and
          length of service requirements.  Contributions equal to 50% of
          the participants' contributions are made by Unit to the plan. 
          Additional contributions may be made by Unit at the discretion of
          Unit's Board of Directors.  Contributions to the plan were
          $564,000 in 1995, $327,000 in 1994, and $260,000 in 1993.  

          9.  STOCK OPTION PLANS

          The Company maintains a 1987 Stock Plan, under which employees
          may be awarded incentive stock options, non-qualified stock
          options, stock awards or opportunities to make direct purchases
          of stock in the Company.  These awards, in the aggregate, are not
          to exceed 1,600,000 shares.  

          During fiscal 1995, 1994 and 1993, options were exercised for
          31,815, 1,000 and  31,818 shares, respectively.

          9.  STOCK OPTION PLANS (continued)
          The Company also maintains a 1990 Non-Employee Director Stock
          Option Plan (the 1990 Plan).  Under the 1990 Plan, each director
          who is not an employee nor an officer of the Company (an "outside
          director") receives an automatic grant of 1,000 non-qualified
          stock options on September 1 of each year, provided that person
          has served as a director since at least December 31 of the
          preceding year.  Each outside director also receives stock
          options as part of the director's compensation under a formula
          approved by the shareholders.  The aggregate options available
          under this plan shall not exceed 250,000 shares.

          11.  INDUSTRY SEGMENT INFORMATION

          A.   The continuing operations of the Company consist of one
          business segment which designs, develops, manufactures, markets
          and services mass flow controllers, which are precision
          instruments sold principally to the semiconductor industry to
          control and measure the mass flow rate of gases.

          The geographic distribution of sales, operating income and
          identifiable assets is as follows:

          12.  COMMITMENTS AND CONTINGENCIES

          A.   The Company is a 50% guarantor on line of credit borrowings
               of its unconsolidated joint venture, ABB Pressure Systems
               AB.  No borrowings were outstanding at May 31, 1995 on the
               $3,000 available line of credit.

                                         -39-
          12.  COMMITMENTS AND CONTINGENCIES (continued)

          B.   Litigation

               (1)  As previously disclosed, Autoclave Engineers, Inc.
                    (Autoclave) had been named as a codefendant, with
                    numerous other companies, in a number of lawsuits filed
                    in state and federal courts in which the plaintiffs
                    alleged personal injury from exposure to asbestos-
                    related products.  To date, Autoclave was named in a
                    total of 17 lawsuits,  all of which were filed by
                    approximately 8,900 employees and former employees of
                    one shipbuilding facility.

                    Autoclave was dismissed from 16 of the lawsuits and is
                    seeking dismissal from the 17th.  The dismissals were
                    all obtained after counsel for Autoclave met with the
                    lead attorney for each of the plaintiff groups and
                    discussed the specific Autoclave product allegedly
                    involved in the lawsuits.  The form of dismissal was
                    merely dependent upon which plaintiff attorney led the
                    plaintiff group.

                    Four of the dismissals were "with prejudice" which
                    means that Autoclave cannot be renamed in the lawsuits. 
                    These four lawsuits involved over 5,800 of the
                    plaintiffs.  The other 12 dismissals were "without
                    prejudice" which means that Autoclave could be renamed
                    in the lawsuits by the plaintiffs.  Management of the
                    Company believes that the possibility of Autoclave
                    being renamed in any of the lawsuits is remote.

                    The Company no longer sells asbestos-containing
                    products.  

               (2)  The Company is involved in a number of other claims and
                    legal proceedings of a nature considered normal to its
                    business, principally product liability matters. 
                    Certain of these cases seek damages which, if awarded,
                    would require sizable payments.  While it is not
                    feasible to predict the outcome of these actions with
                    certainty, management of the Company, based upon
                    available information, believes that any liability that
                    may arise from these proceedings is not expected to
                    have a material adverse effect on the consolidated
                    financial condition or projected results of operations
                    of the Company.


          C.   The Company leases facilities for Unit's headquarters and
               manufacturing operations and all of the Company's outside
               sales offices and service centers.  These leases are
               operating leases, having terms ranging from three to ten
               years, with options to renew for an additional one to five
               years.

                                         -40-
          12.  COMMITMENTS AND CONTINGENCIES (continued)
               Additionally, the Company leases various office equipment
               and vehicles under operating leases expiring during the next
               four years.

               Included in the Consolidated Statement of Income for the
               fiscal years ended May 31, 1995, 1994 and 1993 was rent
               expense, under all operating leases for continuing
               operations, of $1,294, $1,210 and $1,134, respectively.  

               The following is a schedule by year of future minimum rental
               payments required for continuing operations under operating
               leases that have initial or remaining noncancelable lease
               terms in excess of one year as of May 31, 1995:

                              Year Ending May 31,

                              1996                     $ 1,041
                              1997                       1,007
                              1998                         906

                                                       =======
          D.   The Company has identified potential ground water
               contamination at its Erie, PA operating location. 
               Consultations on this matter indicate that further analysis
               and monitoring, but not the need to remediate, is probable
               at this time.  As of May 31, 1995, the Company has accrued
               $100,000 for the probable and estimable costs of further
               analysis and related legal and other costs.  There is
               potential for additional costs such as remediation, further
               monitoring, and legal services, but such costs cannot be
               estimated until the need is established through further site
               analysis expected to take place in the second and third
               quarters of fiscal 1996.

          E.   On June 22, 1995, the Company entered into a Share
               Repurchase Agreement (the Agreement) with its largest
               shareholder, the J & L Levinson Partnership (the
               Partnership).  Under the Agreement, the terms of which are
               contingent upon the closing of the sale of the assets of the
               Autoclave Engineers Group, the Company will repurchase
               220,000 shares of the common stock of the Company from the
               Partnership at a price of $11.75 per share.  The
               Partnership, and its general partners, have agreed not to
               sell, assign, pledge, transfer, or otherwise dispose of
               additional shares of common stock of the Company for a
               period of 18 months following the closing of this repurchase
               of shares.  This Agreement would automatically terminate if

          12.  COMMITMENTS AND CONTINGENCIES (continued)


               the Company would sell substantially all of its remaining
               assets.  This Agreement may be terminated by the Partnership
               if the sale of AEG is not consumated by December 19, 1995;
               or, by the Company if the sale is not consumated by June 21,
               1996.

               The Board of Directors is divided into three classes. 
          Directors are generally elected for terms of three years and
          until their successors are elected and have qualified.  The terms
          of each class expire in successive years at the Annual Meeting of
          Shareholders.  The terms of three directors expire at the 1995
          Annual Meeting of Shareholders.  

               The following table sets forth the names of all directors of
          the Company, their ages, their positions with the Company and the
          respective years in which their terms of office expire.

          Compensation of Directors

               Directors of the Company, other than those who are employees
          of the Company, currently receive $1,000 for each attended
          meeting of the Board.  Directors also receive $1,000 for each
          committee meeting attended unless such meeting is held within one
          day of a meeting of the Board of Directors, in which case
          compensation is at the rate of $500 for each committee meeting. 
          Directors are also reimbursed for out-of-pocket expenses incurred
          in connection with attendance at meetings and other services as a
          director.  

               Beginning September 1, 1993, each director who is neither an
          employee nor an officer of the Company or its subsidiaries is
          automatically granted as additional compensation an option to
          purchase a number of shares of the Company's Common Stock as
          further described herein under "1990 Non-Employee Director Stock
          Option Plan."

          Stock Options

               The 1987 Stock Plan (the "1987 Plan") was adopted by the
          Board of Directors of the Company on June 18, 1987 and approved
          by the shareholders on September 30, 1987.  Prior to the 1990
          Annual Meeting of Shareholders, a total of 605,000 shares of the
          Company's Common Stock (subject to adjustment in certain events)
          was authorized for issuance under the 1987 Plan (after giving
          effect to two 10% stock dividends which occurred subsequent to
          adoption of the 1987 Plan).  At the 1990 Annual Meeting of
          Shareholders, an amendment to the 1987 Plan was approved which
          increased the number of shares of Common Stock authorized for
          issuance thereunder to 1,600,000 shares.  Under the 1987 Plan,
          employees may be awarded incentive stock options ("ISO" or
          "ISOs"), as defined in Section 422(b) (formerly Section 422A(b))
          of the Internal Revenue Code of 1986, as amended (the "Code"),
          and directors, officers, employees and consultants of the Company
          may be granted (i) options which do not qualify as ISOs ("Non-
          qualified Option" or "Non-qualified Options"), (ii) awards of
          stock in the Company and (iii) opportunities to make direct
          purchases of stock in the Company.  ISOs and Non-qualified
          Options are sometimes collectively referred to as "Options."  As
          of August 11, 1995, under the 1987 Plan, stock options have been
          granted to the following officers in the following aggregate
          amounts:  Mr. Levinson, 34,007 shares; Dr. Schilling, 37,050
          shares;  Mr. Doyle, 33,712 shares; Mr. Guelcher, 12,550 shares;
          Mr. Sontag, 22,691 shares; Mr. Pineau, 0 shares; and all
          executive officers as a group, 140,010 shares.  The exercise
          prices of such Options range from $5.89 to $9.09 per share.

          Option Grants in the Last Fiscal Year

               During the fiscal year ended May 31, 1995, there were no
          grants of stock options pursuant to the 1987 Plan to the Named
          Officers reflected in the Summary Compensation Table above.

        Options under the 1987 Plan to purchase an aggregate of 37,000 shares
     of Common Stock were granted by the Board of Directors to all employees as
     a group during the three fiscal years ended May 31, 1995, at an average per
     share exercise price of $6.66.  Options to purchase 50,000 shares of Common
     Stock were granted by the Board of Directors under the 1987 Plan to one
     director for being Chairman of a Special Study Committee of the Board of
     Directors which performed oversight of a strategic planning advisory
     project during the fiscal year ended May 31, 1995.  At August 11, 1995,
     options to purchase 1,046,545 shares remained available for grant under the
     1987 Plan.

          1990 Non-Employee Director Stock Option Plan

             In August 1990, the Board of Directors adopted a stock option
          plan (the "1990 Director Plan") for directors authorizing the
          grant of options for up to 100,000 shares of Common Stock.  The
          1990 Director Plan was approved by the shareholders of the
          Company in September 1990.  Options are granted pursuant to the
          1990 Director Plan only to members of the Board of Directors of
          the Company who are not employees or officers of the Company or
          its subsidiaries ("outside directors").  Each outside director is
          automatically granted on September 1 of each year, without
          further action by the Board of Directors, an option to purchase
          one thousand (1,000) shares of the Company's Common Stock,
          provided that such director shall have served as a director since
          at least December 31 of the preceding year.  The exercise price
          per share of options granted under the 1990 Director Plan is 100%
          of the fair market value of the Company's Common Stock on the
          date the option is granted.  The 1990 Director Plan requires that
          options granted thereunder will expire on the date which is ten
          (10) years from the date of grant.

             In September 1992, the Shareholders approved two amendments
          to the 1990 Director Plan.  The authorized number of options was
          increased to 250,000.  The second amendment provided for each
          outside director to be automatically granted, on September 1 of
          each year beginning in 1993, an additional option to purchase a
          number of shares of the Company's Common Stock equal to a
          fraction, the numerator of which is $1,500 times the number of
          full fiscal quarters during which such person served as a
          director during the preceding 12 months, and the denominator of
          which is 25% of the fair market value of the Common Stock on the
          date the option is granted.

             As of August 11, 1995, 68,643 options have been granted to
          ten present or former directors of the Company under the 1990
          Director Plan at per-share exercise prices that range from $7.00
          to $8.75.  Of the total, 23,643 options were granted at the
          exercise price of $8.50 per share to seven directors during the
          year ended May 31, 1995.  One former director exercised 2,000
          options in June 1995 at an exercise price of $7.25 per share.

             The aggregate number of shares of Common Stock subject to
          options under the 1990 Director Plan, as of August 11, 1995, is
          66,643 shares.

          Deferred Compensation Agreements

             The Company has deferred compensation agreements with certain
          key employees, including Messrs. Levinson, Schilling, Doyle and
          Guelcher.  Under the agreements, the Company will make fixed
          monthly post-retirement payments to such employees until their
          death, in amounts based upon the employees' annual salaries at
          the time of  retirement.  Pursuant to such agreements, the
          employees have agreed to refrain from competing with the Company,
          to maintain the confidentiality of the Company's trade secrets
          and to renounce all personal interest in patents, know-how and
          other intellectual property developed by them during their
          employment by the Company.  

          Involuntary Severance Agreements

             In May 1994, the Company entered into agreements with
          thirteen officers of the Company and its subsidiaries, including
          the Chief Executive Officer and each of the Named Officers,
          (except for Messrs. Levinson and Pineau) providing severance
          benefits in the event they are terminated within two years
          following a change in control of the Company.  Pursuant to such
          agreements, a change in control occurs (i) when any person
          becomes the beneficial owner of securities of the Company
          representing more than 20% of the combined voting power of the
          Company's then outstanding securities; (ii) if, during any period
          of two consecutive years, individuals who constitute the Board of
          Directors cease to constitute a majority of the Board of
          Directors; (iii) if all or substantially all of the Company's
          assets, or the assets of the operating group in which the officer
          is employed, are sold or transferred to a third party; (iv) if
          the Company consolidates or merges with another corporation and
          the Company is not the survivor; or (v) if the Company no longer
          has a class of securities registered pursuant to Section 12 of
          the Exchange Act.  The agreements provide that if the officer is
          terminated following a change in control of the Company, the
          Company shall pay such officer a sum equal to two times his or
          her annual salary and bonus paid during the twelve-month period
          immediately preceding the termination, vest the officer in any
          unvested benefits under any retirement or deferred compensation
          plan in which the officer participates, and pay for a two year
          continuation of such officer's health, life, disability and
          accident insurance.  However, the agreement provides that to the
          extent such benefits would constitute an Excess Parachute Payment
          under Section 280G of the Internal Revenue Code of 1986, the
          severance payments payable thereunder shall be reduced.

          Pension Plan

             The Company maintains a defined benefit pension plan (the
          "Pension Plan") covering all employees (other than employees of
          Unit) who meet general eligibility requirements and who agree to
          contribute 3% of their  salary to the plan.  To be eligible, an
          employee must be 21 years old and complete 1,000 hours of
          service.  The benefits are computed by a formula which takes into
          account an employee's years of service and a percentage of his or
          her average monthly compensation.  The average monthly
          compensation is determined by averaging the compensation for the
          employee's highest five calendar years of earnings.  Compensation
          covered by the Pension Plan includes salaries and annual bonuses. 

             An employee may retire after reaching the age of 55 and
          completing ten years service; however, benefits are reduced if
          such retirement precedes age 65.  

             The following table sets forth the estimated annual benefits
          payable on normal retirement at age 65 under the Pension Plan:

     *  Pensions shown in the table are straight-life annuity amounts notwith-
     standing the availability of joint-and-survivorship pensions at a reduced
     rate.  

             As of May 31, 1995, Mr. Levinson had 27 credited years of
          service under the Pension Plan, Dr. Schilling had five credited
          years of service, Mr. Guelcher had six credited years of service
          and Mr. Sontag had 12 credited years of service.  The
          compensation covered by the Pension Plan for each of these
          persons in fiscal 1995 was approximately equal to the applicable
          amount set forth in the preceding Summary  Compensation Table.

          Bonus Plan

             Management employees of the Company participate in the
          Company's Annual Incentive Compensation Plan (the "Incentive
          Compensation Plan").  Under the Incentive Compensation Plan,
          management employees are eligible to receive cash payments
          according to a weighted average formula based upon corporate,
          group and individual performance.  Such amounts are generally to
          be paid within two and one-half months after the end of the
          fiscal year in which they are earned.  Annual administration of
          the Incentive Compensation Plan, including establishment of
          corporate objectives, participants, awards and payments, is based
          upon recommendations made by the Company's President for approval
          by the Compensation Committee and the Board of Directors.  The 
          Summary Compensation Table set forth above includes amounts
          earned under the Incentive Compensation Plan for performance
          during fiscal 1995.  

             The Company has also from time to time paid discretionary
          bonuses as deemed appropriate by the Board of Directors.

          Unit Profit Sharing Plan

             Unit has a qualified profit sharing 401(k) plan for
          substantially all of its employees who meet certain age and
          length of service requirements.  Contributions equal to 50% of
          the participants' contributions are made by Unit to the plan. 
          Such contributions by Unit shall not exceed 3% of a participant's
          compensation.  Additional contributions may be made by Unit at
          the discretion of Unit's Board of Directors.  Contributions to
          the plan in fiscal 1995 were $564,000.  The  Summary Compensation
          Table set forth above includes amounts accrued under the Unit
          Profit Sharing Plan during fiscal 1995.

          Incentive Plan

             Key management employees of the Company are eligible to
          participate in the Company's Long-Term Incentive Plan (the
          "Plan") which is administered by the Compensation Committee of
          the Board of Directors.  Under the Plan, management employees are
          eligible to receive awards in the form of cash and restricted
          stock awarded pursuant to the 1987 Plan.  Award levels are
          determined by comparing actual economic value created (defined as
          cash flow return in excess of cost of capital multiplied by
          investment) to goals approved by the Compensation Committee. 
          Participation of key management employees in the Plan and the
          proportions of cash and restricted stock to be included in awards
          are subject to the discretion of the Compensation Committee.  The
          cash component of any award under the Plan cannot exceed one-half
          of the award amount.  Awards under the Plan are generally to be
          paid within two and one-half months after the end of the last
          fiscal year of the three-year performance period to which the
          award related.
             In January 1995, the Company entered into an incentive
          agreement with Mr. Pineau providing for aggregate payments of
          $217,152 upon consummation of the sale of Burton Corblin, S.A.
          provided he was an employee on the closing date.
