          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
<PAGE>
                                         -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.

          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.

               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.
<PAGE>
                                    -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.
<PAGE>
                                         -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

          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.

          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.

          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
<PAGE>
                                         -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
<PAGE>


                                         -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 
<PAGE>

                                         -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.

          Item 8.   Financial Statements and Supplementary Data.


                          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.

          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.

          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.

          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

          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:

          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

          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.

          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.

          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,

          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

               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,

          Item 10.  Directors and Executive Officers of the Company.

                                      DIRECTORS



               The Board of Directors is divided into three classes. 
          Directors are generally elected for terms of three years and

          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.

     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

          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:

          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.

                              SHARE REPURCHASE AGREEMENT



               This Share Repurchase Agreement  is made as of June 22, 1995
          by and among James C. Levinson and Marilyn Gasche Levinson
          (collectively, the  Levinsons ); the J. and L. Levinson
          Partnership, a Texas general partnership (the "Seller"); and
          Autoclave Engineers, Inc., a Pennsylvania corporation (the
           Company").

          FACTS:

               The Seller is the owner of shares of Common Stock, $.15 par
          value, of the Company (the "Common Stock"). The Levinsons are the
          sole partners of the Seller.

               The Seller desires to sell, and the Company desires to buy,
          shares of Common Stock owned by the Seller on the terms and
          conditions set forth in this Agreement, in such amount as is set
          forth on Exhibit A hereto (the "Seller Shares").

               The Seller and the Levinsons are willing to agree to refrain
          from making certain transfers of shares of Common Stock.

               The Company is willing to register the shares of Common
          Stock owned by the Seller under the Securities Act of 1933
          (together with the rules and regulations thereunder, the
           Securities Act ) under certain circumstances.

               The Company has received a favorable opinion from its
          investment banker, Needham & Co. Inc., with respect to the
          fairness to the Company from a financial point of view of the
          transactions contemplated by this Agreement.

               In consideration of the covenants and conditions set forth
          in this Agreement, each of the parties agrees as follows:

               1.   Sale of Seller Shares.  The Seller agrees to sell,
          transfer and assign to the Company and, subject to and in
          reliance upon the representations, warranties, terms and
          conditions of this Agreement, the Company agrees to purchase, the
          Seller Shares at the purchase price set forth on Exhibit A
          hereto.

               2.   Closing.  The closing of the purchase and sale of the
          Seller Shares (the "Closing") shall be held concurrently with,
          and is contingent upon, the closing of the sale of the assets of
          the Company s AEG Division as a separate business (the  AEG
          Sale ); provided, however, that (i) if the sale of the AEG
          Division occurs in connection with the sale of substantially all
          of the assets of the Company to or merger of the Company with one
          or more unaffiliated third parties, or (ii) if at the time of the
          closing of the AEG Sale, the Company has entered into a letter of
          intent, agreement in principle or agreement for the sale of
          substantially all of the remaining assets of the Company or the
          sale of the business of the Company through a merger with an 
<PAGE>

                                         -2-

          unaffiliated party, then, in either case, this Agreement shall
          terminate immediately prior to the sale of the AEG Division and
          no party hereto shall have any obligation to the others with
          respect to the Seller Shares. At the Closing, the Seller will
          deliver to the Company a duly executed stock power and a
          certificate representing the Seller Shares against payment of the
          purchase price therefor by delivery of a certified check to the
          Seller.  It shall be a condition of the Company s obligation to
          close the purchase of the Seller Shares that the AEG Sale shall
          have been completed for gross cash proceeds to the Company of at
          least $10,500,000.00 and that no litigation with respect to the
          transactions contemplated by this Agreement shall have been
          commenced or threatened in writing against the Company or members
          of the Company s Board of Directors.  This Agreement may be
          terminated by the Seller and the Levinsons by written notice to
          the Company if the AEG Sale is not consummated within 180 days
          after the date hereof. This Agreement may be terminated by the
          Company by giving written notice to the Levinsons if the AEG Sale
          is not consummated within 365 days after the date hereof. 

               3.   Representations and Warranties of the Levinsons and the
          Seller.  The Levinsons and the Seller represent and warrant as
          follows:

                    (a)  Ownership of Stock. The Seller is the sole record
          and beneficial owner of, and has good and marketable title to,
          the Seller Shares indicated on Exhibit A,  free and clear of any
          liens, encumbrances, claims, charges, options, voting agreements
          and restrictions of any nature, other than restrictions generally
          imposed under state and federal securities laws (collectively, 
          "Encumbrances").  Upon the delivery of the Seller Shares to the
          Company as provided in Section 2 above, the Company will receive
          good and marketable title to the Seller Shares free and clear of
          any and all Encumbrances.

                    (b)  Enforceability of Agreement.  This Agreement has
          been duly executed and delivered by each of the Levinsons and the
          Seller and is enforceable against them in accordance with its
          terms.

                    (c)  No Brokers or Finders.  No person has or will
          have, as a result of the transactions contemplated by this
          Agreement, any right, interest or valid claim against or upon the
          Seller for any commission, fee or other compensation as a finder
          or broker because of any act or omission by the Seller or the
          Levinsons; and the Levinsons and the Seller agree to indemnify
          and hold the Company harmless against any such commissions, fees
          or other compensation arising from any such acts or omissions.

                    (d)  Legends.  Certificates representing all shares of

               4.   Representations and Warranties of the Company.  The
          Company represents and warrants as follows:  

                    (a)  Power and Authority.  The Company has full power
          and authority to execute, deliver and perform this Agreement and
          to make this Agreement its valid and enforceable obligation.  

                    (b)  Enforceability of Agreement.  The execution,
          delivery and performance of this Agreement have been duly
          authorized by all necessary corporate action of the Company. 
          This Agreement has been duly executed and delivered by the
          Company and is enforceable against it in accordance with its
          terms.  

                    (c)  No Conflict.    The execution, delivery and
          performance of this Agreement by the Company in accordance with
          its terms does not and will not conflict with or result in a
          breach of any terms and provisions of, or constitute a  default
          under, the articles of incorporation or bylaws of the Company,
          any law or regulation applicable to the Company, or any agreement
          or instrument to which the Company is a party or by which the
          Company or its assets are bound.

                    (d)  No Brokers or Finders.  No person has or will
          have, as a result of the transactions contemplated by this
          Agreement, any right, interest or valid claim against or upon it 
          for any commission, fee, or other compensation as a finder or
          broker because of any act or omission by the Company (except for
          the fees owing to Needham & Company, Inc., which shall be solely
          the responsibility of the Company); and the Company agrees to
          indemnify and hold the other parties hereto harmless against any
          such commissions, fees or other compensation arising from the
          Company's acts or omissions.

               5.   Standstill.   The Levinsons and the Seller each agree
          not to sell, assign, pledge, transfer (by gift or otherwise) or
          otherwise dispose of, directly or indirectly, any shares of
          Common Stock whatsoever (whether now held or hereafter acquired)
          and agree not to engage in any hedging transactions with respect
          to the Common Stock owned by them that may directly or indirectly
          have an impact on the market price of the Common Stock, in each
          case during the period commencing with and including the date
          hereof and ending on the close of business on the date which is
          eighteen (18) months after the Closing (the "Standstill Period");
          provided, however, that the prohibition contained in this
          Section 5 shall not apply to:

                     (i) gifts in any amount in which (A) each donee agrees
          with the Company in writing to be bound by the restrictions
          contained in this Section 5; and (B) certificates representing
          the shares received by the donee bear the legends set forth on
          Exhibit B hereto; 

                    (ii) sales made pursuant to an effective registration
          statement under the Securities Act;  or
<PAGE>
                                         -4-
                     (iii) lawful "private" sales  in which (A) no such
          shares of Common Stock are sold publicly, or pursuant to Rule 144
          under the Securities Act; and (B) such sales are made solely as a
          private sale pursuant to an exemption under the Securities Act
          other than Rule 144;  (C) the certificates representing the
          shares of Common Stock acquired by the purchaser bear the legends
          set forth on Exhibit B hereto; and (D) each purchaser agrees with
          the Company in writing  to be bound by the restrictions contained
          in this Section 5.
               6.   Registration of the Shares; Compliance with the
          Securities Act.
                    (a)  Registration Requirements.

                         (1)  Subject to the limitations set forth in the
          remainder of this  Section 6(a), the Seller may at any time
          following the Standstill Period give to the Company a written
          request for the registration by the Company under the Securities
          Act of all or any part of the shares of Common Stock owned by it.
          After the receipt of such a request, the Company shall use its
          best efforts in good faith to effect promptly the registration
          under the Securities Act of all such shares as to which a request
          for registration has been received.

                         (2)  The Company shall not be required to effect
          more than one registration pursuant to the provisions of Section
          6(a)(1).  The Company shall not be required to effect any
          registration pursuant to the provisions of Section 6(a)(1) if 
          the Seller shall have sold  at least 150,000 shares of Common
          Stock pursuant to an effective registration statement of the
          Company filed with the Securities and Exchange Commission (the
           Commission ) under the Securities Act.

                         (3)  If the Seller requests the Company to
          withdraw a registration statement requested by it and filed by
          the Company under the Securities Act, the Company shall have no
          further obligations under Section 6(a)(1).

                         (4)  The Company shall not be obligated to effect
          any registration pursuant to the provisions of Section 6(a)(1)
          during the period commencing on the date falling 60 days prior to
          the Company s estimated date of filing of, and ending 90 days
          following the effective date of, any registration statement
          pertaining to any registration initiated by the Company (other
          than with respect to securities registered in connection with
          employee benefit plans).
                         (5)  The Company shall not be required to effect
          any registration pursuant to the provisions of Section 6(a)(1)
          for any 60-day period following receipt of any written request
          for registration, if in the good faith judgment of the Board of
          Directors of the Company, the filing of any registration
          statement during such 60-day period would adversely affect a
          material proposed or pending acquisition, merger or other
          material corporate event to which the Company reasonably expects
          to conclude.
<PAGE>



                                         -5-


                         (6)  The Company shall not be required to effect
          any registration pursuant to the provisions of Section 6(a)(1)
          with respect to any shares of Common Stock that may be sold
          pursuant to the provisions of Rule 144(k), or any rule of similar
          effect, of the Commission 

                         (7)  The Seller shall not effect sales of any
          securities pursuant to any registration pursuant to the
          provisions of Section 6(a)(1) after receipt of notice from the
          Company to suspend sales to permit the Company to correct or
          update such registration statement, which the Company shall
          undertake to do as soon as practicable; in such event, the period
          of time described in Section 6(b)(1)  shall be extended by a
          period of days equal to the period such suspension is in effect.

                    (b)  Registration Procedures.

                         (1)   With respect to any registration statement
          filed by the Company pursuant to Section 6(a)(1) (the
           Registration Statement ), the Company will prepare and file with
          the  Commission  such amendments and supplements thereto and to
          the prospectus used in connection therewith as may be necessary
          to comply with the Securities Act  for a period of sixty (60)
          days after the effective date of such Registration Statement.
          After the conclusion of such 60-day period, the Seller shall not
          make any sales of Common Stock pursuant to such Registration
          Statement, and such Registration Statement may be withdrawn by
          the Company.

                         (2)  The Company will furnish to the Seller with
          respect to the securities registered under the Registration
          Statement (and to each underwriter, if any, of such securities)
          such number of copies of prospectuses and preliminary
          prospectuses in conformity with the requirements of the
          Securities Act and such other documents as the Seller may
          reasonably request, in order to facilitate the public sale or
          other disposition of all or any of such securities by the Seller;
          provided, however, that the obligation of the Company to deliver
          copies of prospectuses or preliminary prospectuses to the Seller
          shall be subject to the receipt by the Company of reasonable
          assurances from the Seller that the Seller will comply with the
          applicable provisions of the Securities Act and of such other
          securities or blue sky laws as may be applicable in connection
          with any use of such prospectuses or preliminary prospectuses;

                         (3)  The Company will file documents required of
          the Company for blue sky clearance in states specified in writing
          by the Seller and will use its reasonable best efforts to obtain
          all such clearances; provided, however, that the Company shall
          not be required to qualify to do business or consent to service
          of process in any jurisdiction in which it is not now so
          qualified or has not so consented; and
<PAGE>
                                         -6-


                         (4)  The Company will bear all expenses in
          connection with each Registration Statement and with the
          procedures specified in this Section 6(b) and the registration of
          the shares pursuant to the Registration Statement, other than
          fees and expenses, if any, of underwriters and of counsel or
          other advisers to the Seller.

                         (5)  In the event that any registration pursuant
          to Section 6(a) involves an underwritten public offering, the
          Company will execute an underwriting agreement containing
          customary terms.

                         (6)  The Company will give the Sellers, any
          underwriters and their respective representatives reasonable and
          customary access to the books, records and properties of the
          Company and will make available its officers and representatives
          to discuss the business and affairs of the Company in order to
          permit the Seller and underwriter to conduct a reasonable due
          diligence investigation of the Company within the meaning of the
          Securities Act.

                         (7)  The Company will use its best efforts to
          furnish to the Seller and underwriter, if any, an opinion of
          counsel for the Company and a  cold comfort  letter of its
          auditors, in each case, covering matters customarily covered in
          such documents in underwritten public offerings.

                         (8)  While any Registration Statement is
          effective, the Company will immediately notify the Seller of
          (i) any event which could cause the Registration Statement to
          contain an untrue statement, or (ii) any communication from the
          Commission with respect to the Registration Statement.

                    (c)  Indemnification.  For the purpose of this
          Section 6(c):

                         (1)  The term "Selling Shareholder" shall mean the
          Seller if it has sold shares of Common Stock pursuant to the
          Registration Statement,  and any affiliate of  the Seller,
          including the Levinsons;

                         (2)  The term "Registration Statement" shall
          include any preliminary prospectus, final prospectus, exhibit,
          supplement or amendment included in or relating to the
          Registration Statement; and

                         (3)  The term "untrue statement" shall mean any
          untrue statement or alleged untrue statement of a material fact
          in the Registration Statement, or any omission or alleged
          omission to state in the Registration Statement a material fact
          required to be stated therein or necessary to make the statements
          therein, in the light of the circumstances under which they were
          made, not misleading.

                                         -7-


                    The Company agrees to indemnify and hold harmless each
          Selling Shareholder from and against any losses, claims, damages
          or liabilities to which such Selling Shareholder may become
          subject (under the Securities Act or otherwise) insofar as such
          losses, claims, damages or liabilities (or actions or proceedings
          in respect thereof) arise out of, or are based upon, any untrue
          statement contained in the Registration Statement, and the
          Company will reimburse such Selling Shareholder for any legal or
          other expenses reasonably incurred in investigating, defending or
          preparing to defend any such action, proceeding or claim;
          provided, however, that the Company  shall not be liable in any
          such case to the extent that such loss, claim, damage or
          liability arises out of, or is based upon, an untrue statement
          made in such Registration Statement in reliance upon and in
          conformity with written information furnished to the Company by
          or on behalf of such Selling Shareholder specifically for use in
          preparation of the Registration Statement, or the failure of such
          Selling Shareholder to comply with the covenants and agreements
          contained herein respecting sale of its securities.

                    The Seller and the Levinsons agrees to indemnify and
          hold harmless the Company and  (and each person, if any, who
          controls the Company within the meaning of Section 15 of the
          Securities Act, each officer of the Company who signs the
          Registration Statement and each director of  the Company) from
          and against any losses, claims, damages or liabilities to which
          the Company  (or any such officer, director or controlling
          person) may become subject (under the Securities Act or
          otherwise), insofar as such losses, claims, damages or
          liabilities (or actions or proceedings in respect thereof) arise
          out of, or are based upon, any failure of the Seller to comply
          with the covenants and agreements contained herein, or any untrue
          statement contained in the Registration Statement if such untrue
          statement was made in reliance upon and in conformity with
          written information furnished by or on behalf of the Seller
          specifically for use in preparation of the Registration
          Statement, and the Seller will reimburse the Company  (or such
          officer, director or controlling person), as the case may be, for
          any legal or other expenses reasonably incurred in investigating,
          defending or preparing to defend any such action, proceeding or
          claim.

                    Promptly after receipt by any indemnified person of a
          notice of a claim or the beginning of any action in respect of
          which indemnity is to be sought against an indemnifying person
          pursuant to this Section 6(c), such indemnified person shall
          notify the indemnifying person in writing of such claim or of the
          commencement of such action, and, subject to the provisions
          hereinafter stated, in case any such action shall be brought
          against an indemnified person and such indemnifying person shall
          have been notified thereof, such indemnifying person shall be
          entitled to participate therein, and, to the extent it shall
          wish, to assume the defense thereof, with counsel reasonably
          satisfactory to such indemnified person.  After notice from the
          indemnifying person to such indemnified person of its election to
<PAGE>
                                         -8-
          assume the defense thereof, such indemnifying person shall not be
          liable to such indemnified person for any legal expenses
          subsequently incurred by such indemnified person in connection
          with the defense thereof, provided, however, that if there exists
          or shall exist a conflict of interest that would make it
          inappropriate, in the opinion of counsel to the indemnified
          person, for the same counsel to represent both the indemnified
          person and such indemnifying person or any affiliate or associate
          thereof, the indemnified person shall be entitled to retain its
          own counsel at the expense of such indemnifying person; provided,
          however, that no indemnifying person shall be responsible for the
          fees and expenses of more than one separate counsel for all
          indemnified parties.
               If the indemnification provided for in this Section 6(d) is
          for any reason unavailable, then each indemnifying party shall
          contribute to the amount paid or payable by the indemnified party
          (including legal fees and other expenses) in proportion  to their
          relative fault with respect to the untrue statement or other fact
          giving rise to the amount so paid or payable, determined by
          reference to who supplied the information giving rise to the
          untrue statement and who had the opportunity to correct the
          untrue statement or to remedy any other defect, as well as other 
          equitable considerations, but not by reference to the indemnified
          party s stock ownership in the Company.
               8.   Counterparts.  This Agreement may be executed in
          counterparts, each of which will be deemed an original but all of
          which will be deemed one instrument.

               9.   Survival of Representations and Warranties.  All
          representations and warranties made in this Agreement or any
          other instrument or document delivered in connection herewith,
          shall survive the execution and delivery hereof.

               10.  Prior Agreements.  This Agreement constitutes the
          entire agreement between the parties with respect to its subject
          matter and supersedes any prior understandings or agreements
          concerning such subject matter.

               11.  Severability.  The invalidity or unenforceability of
          any provision hereof shall in no way affect the validity or
          enforceability of any other provision.

               12.  Governing Law.  This Agreement shall be governed by,
          and construed in accordance with,  Pennsylvania  law.

               13.  Headings.  Section headings in this Agreement are
          included herein for convenience of reference only and shall not
          constitute a part of the Agreement for any other purpose.

               14.  Amendments and Waivers.  Changes in or additions to
          this Agreement may be made, and compliance with any covenant or
          other provision herein set forth may be omitted or waived, only
          by an instrument in writing executed by all of the parties
          hereto.

               15.  Non-Assignability.  The provisions of this Agreement
          are non-assignable, except that the estate of the survivor of
          James C. Levinson and Marilyn Gasche Levinson shall be entitled
          to the benefits of, and shall be subject to the provisions of,
          this Agreement.

               16.  Joint and Several Obligations.  The Levinsons jointly
          and severally agree to cause the Seller to perform all of its
          obligations hereunder, and all obligations of the Levinsons
          and/or of the Seller shall be joint and several, whether so
          expressed or not. The term  Seller  shall be deemed to include
          the Levinsons if the Seller shall be dissolved or if any of the
          shares of Common Stock owned by the Seller shall be distributed
          to the Levinsons, but the provisions of this sentence shall not
          create any duplicative obligations on the part of the Company.

               17.  Further Assurances.  Subject to the specific terms of
          this Agreement, each of the parties hereto shall make, execute,

          and take all such other actions, as may be seasonably necessary
          in order to effectuate the purpose of this Agreement and to

                         (i)  Any claim whatsoever arising out of the use

               2.05.  Assignment of Contracts and Rights.  Anything in this
          Agreement to the contrary notwithstanding, this Agreement shall
          not constitute an agreement to assign any Purchased Asset or any
          claim or right or any benefit arising thereunder or resulting
          therefrom if an attempted assignment thereof, without consent of
          a third party thereto, would constitute a breach or other
          contravention thereof or in any way adversely affect the rights
          of Buyer or ACLV thereunder.  ACLV and Buyer will use their best
          efforts (but without any payment of money by ACLV or Buyer) to
          obtain the consent of the other parties to any such Purchased
          Asset or claim or right or any benefit arising thereunder for the
          assignment thereof to Buyer as Buyer may request.  If such
          consent is not obtained, or if an attempted assignment thereof
          would be ineffective or would adversely affect the rights of ACLV
          thereunder so that Buyer would not in fact receive all such
          rights, ACLV and Buyer will cooperate in a mutually agreeable
          arrangement under which Buyer would obtain the benefits and
          assume the obligations thereunder in accordance with this
          Agreement, including subcontracting, sub-licensing, or subleasing
          to Buyer, or under which ACLV would enforce for the benefit of
          Buyer, with Buyer assuming ACLV's obligations, any and all rights
          of ACLV against a third party thereto.  ACLV will promptly pay to
          Buyer when received all monies received by ACLV under any
          Purchased Asset or any claim or right or any benefit arising
          thereunder, except to the extent the same represents an Excluded
          Asset.  

               2.06.  Purchase Price.  (a) The purchase price for the
          Purchased Assets (the "Purchase Price") is (i) Fifteen Million
          Five Hundred Thousand Dollars ($15,500,000.00) in cash,
          (ii) Seven Hundred and Fifty Thousand Dollars ($750,000) by
          Buyer s promissory note in the form and on the terms set forth as
          Exhibit B, (iii) the assumption of the Assumed Liabilities and
          (iv) the  Margin Sharing Fee  described in Section 8.03 below.
          The cash portion of the Purchase Price shall be paid as provided
          in Section 2.07 below.

                    (b)  On or prior to the Closing, the parties shall
          agree on an Allocation Statement setting forth the value of the
          Purchased Assets and of the Covenant Not to Compete described in
          Section 7.04 hereof, which shall be the allocation of the
          Purchase Price (together with the Assumed Liabilities) among the
          Purchased Assets and the Covenant Not to Compete.

               2.07.  Closing.  The closing (the "Closing") of the purchase
          and sale of the Purchased Assets and the assumption of the
          Assumed Liabilities hereunder shall take place at the offices of
          ACLV as soon as possible, but in no event later than five
          Business Days after satisfaction of the conditions set forth in
          Article X, or at such other time or place as Buyer and ACLV may
          agree.  At the Closing,

                    (a)  Buyer shall deliver to ACLV a certified or
          official bank check payable to the order of ACLV, or make a wire
          transfer to an account designated by ACLV, in the amount of
          $15,500,000.00.

                    (b)  ACLV and Buyer shall enter into an Assignment and
          Assumption Agreement substantially in the form attached hereto as
          Exhibit A, and ACLV shall deliver to Buyer such deeds, bills of
          sale, endorsements, consents, assignments and other good and
          sufficient instruments of conveyance and assignment (the
          "Conveyance Documents") as are necessary or appropriate to vest
          in Buyer all right, title and interest in, to and under the
          Purchased Assets.  ACLV and Buyer shall also execute and deliver
          all such instruments, documents and certificates as may be
          reasonably requested by the other party that are necessary,
          appropriate or desirable for the consummation at the Closing of
          the transactions contemplated by this Agreement.

                    (c)  Buyer shall execute and deliver to ACLV the
          Subordinated Note in the form of Exhibit B.

               ACLV hereby represents and warrants to Buyer that:

               3.01.  Corporate Existence and Power.  ACLV is a corporation
          duly incorporated, validly existing and in good standing under
          the laws of its jurisdiction of incorporation, and has all
          corporate powers and all material governmental licenses,

          business as now conducted.

               3.02.  Corporate Authorization; Transferred Subsidiaries. 
          (a) The execution, delivery and performance by ACLV of this
          Agreement, and the consummation by ACLV of the transactions
          contemplated hereby are within ACLV's corporate powers and have
          been duly authorized by all necessary corporate action on the
          part of ACLV.  This Agreement constitutes a valid and binding

          All of the outstanding capital stock of, or other ownership
          interests in, each Transferred Subsidiary, is owned by ACLV,
          directly or indirectly, free and clear of any Lien and free of
          any other limitation or restriction (including any restriction on
          the right to vote, sell or otherwise dispose of such capital
          stock or other ownership interests).  There are no outstanding
          (i) securities of ACLV or any Transferred Subsidiary convertible
          into or exchangeable for shares of capital stock or other voting 
          securities or ownership interests in any Transferred Subsidiary
          or (ii) options or other rights to acquire from ACLV, or any
          obligation of any Transferred Subsidiary to issue, any capital
          stock, voting securities or other ownership interests in, or any

          stock, voting securities or ownership interests in, any
          Transferred Subsidiary (the items in clauses (i) and (ii) being
          referred to collectively as the "Transferred Subsidiary
          Securities").  There are no outstanding obligations of ACLV or
          any Transferred Subsidiary to repurchase, redeem or otherwise
          acquire any outstanding Transferred Subsidiary Securities.

               3.03.  Governmental Authorizations.  The execution delivery
          and performance by ACLV of this Agreement do not require any
          action by or in respect of, or filing with, any governmental
          body, agency, official or authority other than compliance with
          any applicable requirements of the HSR Act.

          (i) contravene or conflict with the corporate charter or bylaws
          of ACLV, (ii) contravene or conflict with or constitute a
          violation of any provision of any law, regulation, judgment,
          injunction, order or decree binding upon or applicable to ACLV or

          cancellation or acceleration of any right or obligation of ACLV
          or to a loss of any benefit relating to the Business to which
          ACLV is entitled under any provision of any material agreement,
          contract or other instrument binding upon ACLV or by which any of
          the Purchased Assets is or may be bound or any Permit or (iv)
          result in the creation or imposition of any Lien on any Purchased
          Asset, other than Permitted Liens.

          sets forth each agreement, contract or other instrument binding
          upon ACLV or any Permit requiring a consent as a result of the
          execution, delivery and performance of this Agreement or the
          consummation of the transactions contemplated hereby, except such
          consents as would not, individually or in the aggregate, have a
          Material Adverse Effect if not received by the Closing Date (each
          such consent, a "Required Consent").

                    (b)  Schedule 3.05(b) sets forth every other consent

                         (iv) Except as set forth on Schedule 3.08(c)(iv),
          the plants, buildings, structures and equipment included in the
          Purchased Assets have no material defects, are in good operating
          condition and repair and have been reasonably maintained
          consistent with standards generally followed in the industry
          (giving due account to the age and length of use of same,
          ordinary wear and tear excepted), are suitable for their present
          uses and, in the case of plants, buildings and other structures
          (including without limitation, the roofs thereof), are
          structurally sound.

                         (v)  None of the material structures on the Real
          Property encroaches upon real property of another Person, and no
          structure of any other person substantially encroaches upon any
          Real Property.

                    (d)  No Purchased Asset is subject to any Lien, except:
                         (i)  Liens disclosed in the Financial Statements
          or the Schedules attached hereto;
                         (ii) Liens for taxes not yet due or being
          contested in good faith (and for which adequate accruals or
          reserves have been established on the Balance Sheet); or

                         (iii)     Liens that do not materially detract
          from the value of such Purchased Asset as now used, or materially
          interfere with any present or intended use of such Purchased
          Asset (clauses (ii) and (iii) are, collectively, the "Permitted
          Liens").

                    (e)  No violation of any law, regulation or ordinance
          (including, without limitation, laws, regulations or ordinances
          relating to zoning, environmental, city planning or similar
          matters) relating to the Business or any Purchased Asset
          currently exists or has existed at any time since May 31, 1992,
          except for violations that have not had and would not reasonably
          be expected to have, individually or in the aggregate, a Material
          Adverse Effect.  There are no developments affecting any of the
          Purchased Assets pending or, to the knowledge of ACLV threatened,
          which might materially detract from the value of such Purchased
          Assets, materially interfere with any present or intended use of
          any such Purchased Assets or materially adversely affect the
          marketability of such Purchased Assets.

               3.09.  Sufficiency of Purchased Assets.  The Purchased
          Assets plus certain of the Excluded Assets constitute, and on the
          Closing Date will constitute, all of the assets or property used
          or held for use primarily in the Business. 

               3.10.  Title to Purchased Assets.  Upon consummation of the
          transactions contemplated hereby, Buyer will have acquired good
          and marketable title in and to, or a valid leasehold interest in,
          each of the Purchased Assets, free and clear of all Liens, except
          for Permitted Liens.

               3.11.  No Undisclosed Material Liabilities.  To the
          knowledge of ACLV, there are no material liabilities of the
          Business of any kind whatsoever, whether accrued, contingent,
          absolute, determined, determinable or otherwise, and there is no
          existing condition, situation or set of circumstances which could
          reasonably be expected to result in such a material liability,
          other than:

                    (i)  liabilities disclosed or provided for in the
          Balance Sheet or in the notes thereto or disclosed in the
          Schedules to this Agreement; and

                    (ii) liabilities incurred in the ordinary course of
          business consistent with past practice since the Balance Sheet
          Date.

               3.12.  Litigation.  Except as disclosed in Schedule 3.12,
          there is no action, suit, investigation or proceeding pending
          against or affecting, or to the knowledge of ACLV, any action,
          suit, investigation or proceeding that would reasonably be
          expected to have a Material Adverse Effect that  has been
          threatened against or affecting, the Business or any Purchased
          Asset before any court or arbitrator or any governmental body,
          agency or official or that in any manner challenges or seeks to
          prevent, enjoin, alter or materially delay the transactions
          contemplated hereby.

               3.13.  Material Contracts.  (a)  Except for the Contracts
          disclosed in Schedule 3.13 or any other Schedule to this
          Agreement, with respect to the Business, ACLV is not a party to
          or subject to:

          outstanding purchase orders issued in the ordinary course of
          business and not pursuant to a recurring obligation;

                    (iii)     any sales, distribution or other similar
          agreement providing for the sale by ACLV of materials, supplies,
          goods, services, equipment or other assets that provides for
          annual payments to ACLV of, or pursuant to which in the last year
          ACLV received in the aggregate, $50,000 or more;

                    (iv) any partnership, joint venture or other similar
          contract arrangement or agreement;

                    (v)  any contract relating to indebtedness for borrowed
          money or the deferred purchase price of property (whether
          incurred, assumed, guaranteed or secured by an asset), except
          contracts relating to indebtedness incurred in the ordinary
          course of business in an amount not exceeding $50,000;

                    (vi) any license agreement, franchise agreement or
          agreement in respect of similar rights granted to or held by
          ACLV;

                    (vii)     any agency, dealer, sales representative or
          other similar agreement;

                    (viii)    any agreement, contract or commitment that
          substantially limits the freedom of ACLV to compete in any line
          of business or with any Person or in any area or to own, operate,
          sell, transfer, pledge or otherwise dispose of or encumber any
          Purchased Asset or that would so limit the freedom of the Buyer
          after the Closing Date;


                                         -15-
<PAGE>


                    (ix) any agreement, contract or commitment which is or
          relates to an agreement with or for the benefit of any subsidiary
          of ACLV; or

                    (x)  any other agreement, contract or commitment not
          made in the ordinary course of business which is material to the
          Business taken as a whole.

               (b)  Each Contract disclosed in any Schedule to this
          Agreement or required to be disclosed pursuant to Section 3.13(a)
          is valid and binding agreement of ACLV and is in full force and
          effect, and neither ACLV nor, to the knowledge of ACLV, any other
          party thereto is in default in any material respect under the
          terms of any such Contract, nor, to the knowledge of ACLV, has
          any event or circumstance occurred that, with notice or lapse of
          time or both, would constitute any material event of default
          thereunder.

               3.14.  Licenses and Permits.  Schedule 3.14 correctly
          described each material license, franchise, permit or other
          similar authorization affecting, or relating in any way to, the
          Business, together with the name of the government agency or
          entity issuing such license or permit (the "Permits").  Except as
          set forth on the Schedule 3.14, such Permits are valid and in
          full force and effect and, assuming the related Required Consents
          and Other Consents have been obtained prior to the Closing Date,
          are transferable by ACLV and will not be terminated or impaired
          or become terminable as a result of the transactions contemplated
          hereby.  Upon consummation of such transactions, Buyer will,
          assuming the related Required Consents and Other Consents have
          been obtained prior to the Closing Date, have all of the right,
          title and interest in all the Permits.

               3.15.  Insurance Coverage.  Schedule 3.15 sets forth a list
          of all insurance policies and fidelity bonds covering the
          Purchased Assets, the business and operations of the Business and
          its employees.  There is no claim by ACLV pending under any of
          such policies or bonds as to which coverage has been questioned,
          denied or disputed by the underwriters of such policies or bonds. 
          All premiums payable under all such policies and bonds have been
          paid and ACLV is otherwise in full compliance with the terms and
          conditions of all such policies and bonds.  Such policies of
          insurance and bonds (or other policies and bonds providing
          substantially similar insurance coverage) have been in effect
          since before May 31, 1992 and remain in full force and effect.  

               3.16.  Compliance with Laws.  ACLV is not in violation of,
          has not since May 31, 1992 violated, and to ACLV's knowledge is
          not under investigation with respect to and has not been
          threatened to be charged with or given notice of any violation
          of, any law, rule, ordinance or regulation, or judgment, order or
          decree entered by any court, arbitrator or governmental
          authority, domestic or foreign, applicable to the Purchased 


                                         -16-
<PAGE>
          Assets or the conduct of the Business, except for violations that
          have not had and could not reasonably be expected to have,
          individually or in the aggregate, a Material Adverse Effect.

               3.17.  Inventories.  The inventories set forth in the
          Balance Sheet were properly stated therein at the lesser of cost
          or fair market value determined in accordance with generally
          accepted accounting principles consistently maintained and
          applied by ACLV.  Since the Balance Sheet Date, the inventories
          related to the Business have been maintained in the ordinary
          course of business.  All such inventory is owned free and clear
          of all Liens.  All of the inventory recorded on the Balance Sheet
          consists of, and all inventory related to the Business on the
          Closing Date will consist of, items usable or saleable in the
          normal course of Business consistent with past practices and are
          and will be in a quantity sufficient for the normal operation of
          the Business in accordance with past practice.

               3.18.  Receivables.  All accounts, notes receivable and
          other receivables (other than receivables collected since the
          Balance Sheet Date) reflected on the Balance Sheet are, and all
          accounts and notes receivable arising from or otherwise relating
          to the Business at the Closing Date will be, valid and genuine.
               3.19.  Intellectual Property. (a) Schedule 3.19 sets forth a
          list of all Proprietary Rights used in the Business by ACLV and
          described in clauses (A) through (C) of the definition of such
          term in Section 1.01, specifying as to each, as applicable: 
          (i) the nature of such Proprietary Right; (ii) the owner of such
          Proprietary Right; (iii) the jurisdictions in which such
          Proprietary Right has been issued or registered or in which an
          application for such issuance or registration has been filed,
          including the respective registration or application numbers; and
          (iv) material licenses, sublicenses and other agreements as to
          which ACLV or any of its subsidiaries is a party and pursuant to
          which any Person is authorized to use such Proprietary Right,
          including the identity of all parties thereto, a description of
          the nature and subject matter thereof, the applicable royalty and
          the term thereof.
                    (b)  Except as disclosed in Schedule 3.19, (i) ACLV has
          not during the three years preceding the date of this Agreement
          been sued or charged in writing with or been a defendant in any
          claim, suit, action or proceeding relating to the Business that
          has not been finally terminated prior to the date hereof and that
          involves a claim of infringement of any of ACLV s Proprietary
          Rights and (ii) ACLV has no knowledge of any other claim or
          infringement by ACLV, and no knowledge of any continuing
          infringement by any other Person of any of ACLV s Proprietary
          Rights.  None of ACLV s Proprietary Rights is subject to any
          outstanding order, judgment, decree, stipulation or agreement
          restricting the use thereof by ACLV with respect to the Business
          or restricting the licensing thereof by ACLV to any Person.  ACLV
          has not entered into any agreement to indemnify any other Person
          against any charge of infringement of any of ACLV s Proprietary
          Rights.

          development results and other know-how relating to the Business,

          confidentiality thereof, has been disclosed by ACLV or any
          Affiliate thereof to any Person other than employees,
          representatives and agents of ACLV.

                                     TAX MATTERS 

               5.01.  Tax Definitions.  The following terms, as used
          herein, have the following meanings:

          and penalties due thereon and payable by it, for the Pre-Closing
          Tax Period which will have been required to be paid on or prior
          to the Closing Date, the non-payment of which would result in a
          Lien on any Purchased Asset, would otherwise adversely affect the
          Business or would result in Buyer becoming liable or responsible
          therefor.

                    (b)  ACLV has established, in accordance with generally
          accepted accounting principles applied on a basis consistent with
          that of preceding periods, adequate reserves for  the payment of,

          and penalties which arise from or with respect to the Purchased
          Assets or the operation of the Business and are incurred in or
          attributable to the Pre-Closing Tax Period, the non-payment of
          which would result in a Lien on any Purchased Asset, would
          otherwise adversely affect the Business or would result in Buyer
          becoming liable therefor.

               5.03.  Tax Cooperation; Allocation of Taxes.  (a) Buyer and
          ACLV agree to furnish or cause to be furnished to each other,

          audit by any taxing authority, and the prosecution or defense of
          any claim, suit or proceeding relating to any Tax return.  ACLV
          and Buyer shall cooperate with each other in the conduct of any
          audit or other proceeding related to Taxes involving the Business
          and each shall execute and deliver such powers of attorney and
          other documents as are necessary to carry out the intent of this
          paragraph (a) of Section 5.03.

                    (b)  All real property taxes, personal property taxes
          and similar ad valorem obligations levied with respect to the
          Purchased Assets for a taxable period which includes (but does
          not end on) the Closing Date (collectively, the "Apportioned
          Obligations") shall be apportioned between ACLV and Buyer as of
          the Closing Date based on the number of days of such taxable
          period included in the Pre-Closing Tax Period and the number of
          days of such taxable period included in the Post-Closing Tax
          Period.  ACLV shall be liable for the proportionate amount of
          such taxes that is attributable to the Pre-Closing Tax Period. 
          Within 90 days after the Closing, ACLV and Buyer shall present a
          statement to the other setting forth the amount of reimbursement
          to which each is entitled under this Section 5.03(b) together
          with such supporting evidence as is reasonably necessary to
          calculate the proration amount.  The proration amount shall be
          paid by the party owing it to the other within 10 days after
          delivery of such statement.  Thereafter, ACLV shall notify Buyer
          upon receipt of any bill for real or personal property taxes
          relating to the Purchased Assets, part or all of which are
          attributable to the Post-Closing Tax Period, and shall promptly
          deliver such bill to Buyer who shall pay the same to the
          appropriate taxing authority, provided that if such bill covers
          the Pre-Closing Tax Period, ACLV shall also remit prior to the
          due date of assessment to Buyer payment for the proportionate
          amount of such bill that is attributable to the Pre-Closing Tax
          Period.  If either ACLV or Buyer shall thereafter make a payment
          for which it is entitled to reimbursement under this
          Section 5.03(b), the other party shall make such reimbursement
          promptly but in no event later than 30 days after the
          presentation of a statement setting forth the amount of
          reimbursement to which the presenting party is entitled along
          with such supporting evidence as is reasonably necessary to
          calculate the amount of reimbursement.  Any payment required
          under this Section and not made within 10 days of delivery of the
          statement shall bear interest at the rate per annum determined,
          from time to time, under the provisions of Section 6621(a)(2) of
          the Code for each day until paid.

                    (c)  Any transfer, documentary, sales, use or other
          Taxes assessed upon or with respect to the transfer of the
          Purchased Assets to Buyer and any recording or filing fees with
          respect thereto shall be the responsibility of ACLV.

          (c)agree or commit to do any of the foregoing.

          ACLV will not (i) take or agree or commit to take any action that

          inaccurate in any respect at, or as of any time prior to, the
          Closing Date or (ii) omit or agree or commit to omit to take any
          action necessary to prevent any such representation or warranty
          from being inaccurate in any respect at any such time.

          7.02.  Access to Information.  From the date hereof until the
          Closing Date, ACLV (a) will give Buyer, its counsel, financial

          foregoing, Buyer shall not have access to personnel records of
          ACLV relating to individual performance or evaluation records,
          medical histories or other information that in ACLV's good faith

          7.03.  Notices of Certain Events.  ACLV shall promptly notify
          Buyer of:

          (i)any notice or other communication from any Person alleging
          that the consent of such Person is or may be required in
          connection with the transactions contemplated by this Agreement;

          (ii)any notice or other communication from any governmental or
          regulatory agency or authority in connection with the
          transactions contemplated by this Agreement; and

          (iii)any actions, suits, claims, investigations or proceedings
          commenced or, to the best of its knowledge threatened against,
          relating to or involving or otherwise affecting ACLV or the
          Business that, if pending on the date of this Agreement, would
          have been required to have been disclosed pursuant to
          Section 3.12 or that relate to the consummation of the
          transactions contemplated by this Agreement.

          7.04.  Noncompetition.  (a) ACLV agrees that for a period of
          three full years from the Closing Date, it will not:

          (i)engage, either directly or indirectly, as a principal or for
          its own account, solely or jointly with others, or through any
          form of ownership in another Person, or otherwise, in any
          business that competes with the Business as it exists on the
          Closing Date in any countries or regions in which the Business is
          currently conducted; provided that nothing herein shall prohibit
          the acquisition by ACLV or any of its Affiliates of a diversified
          company having not  more than 10% of its sales (based on its
          latest published annual audited financial statements)
          attributable to any business that competes with the Business; or

          (ii)employ or solicit, or receive or accept the performance of
          services by, any Transferred Employee; or

          (iii) advise any customer or supplier of the Business with
          respect to its business relationship with the Business.

          (b)If any provision contained in this Section shall for any
          reason be held invalid, illegal or unenforceable in any respect,
          such invalidity, illegality or unenforceability shall not affect
          any other provisions of this Section, but this Section shall be
          construed as if such invalid, illegal or unenforceable provision
          had never been contained herein.  It is the intention of the
          parties that if any of the restrictions or covenants contained
          herein is held to cover a geographic area or to be for a length
          of time which is not permitted by applicable law, or in any way
          construed to be too broad or to any extent invalid, such
          provision shall not be construed to be null, void and of no
          effect, but to the extent such provision would be valid or
          enforceable under applicable law, a court of competent
          jurisdiction shall construe and interpret or reform this Section
          to provide for a covenant having the maximum enforceable 
                                         -29-
<PAGE>


          geographic area, time period and other provisions (not greater
          than those contained herein) as shall be valid and enforceable
          under such applicable law.  ACLV acknowledges that Buyer would be
          irreparably harmed by any breach of this Section and that there
          would be no adequate remedy at law or in damages to compensate
          Buyer for any such breach.  ACLV agrees that Buyer shall be
          entitled to injunctive relief requiring specific performance  by
          ACLV of this Section, and ACLV consents to the entry thereof.

          7.05  Trademarks; Tradenames.  As soon as practicable after the
          Closing Date, ACLV shall eliminate the use of all of the
          trademarks, tradenames, service marks and service names used in
          the Business, in any of their forms or spellings, on all
          advertising, stationery, business cards, checks, purchase orders
          and acknowledgments, customer agreements and other contracts and
          business documents, and shall change the corporate name of ACLV
          so as to bear no resemblance to the current name of ACLV;
          provided that ACLV shall not be required to call a special
          stockholders meeting to change its corporate name, but shall in
          the interim do business under a name that bears no resemblance to
          its current name.

          7.06.  No Negotiation with Third Parties.  From the date hereof
          until the earlier of the Closing Date or the date on which this
          Agreement is terminated, ACLV agrees that neither ACLV, nor any
          of its Affiliates, agents or representatives shall, directly or
          indirectly, encourage, solicit or engage in any discussions or
          negotiations with, or provide any information to, any Person
          concerning the possible acquisition by such third party of all or
          any part of the Business or the Purchased Assets other than as
          contemplated or permitted by this Agreement.  ACLV agrees
          promptly to notify Buyer of any contact by any Person with
          respect to any such possible acquisition.

          7.07.Environmental Remediation.  ACLV will deliver to Buyer,
          within ninety (90) days of the Closing Date, the results of a
          Phase I environmental assessment (the  Phase I ).  If the results
          of the Phase I establish any environmental condition which ACLV
          is required by applicable law to remediate, ACLV will undertake
          to remediate that environmental condition as soon as practicable.

                                  COVENANTS OF BUYER
          Buyer agrees that:

          8.01.  Confidentiality.  Prior to the Closing Date and after any
          termination of this Agreement, Buyer and its Affiliates will
          hold, and will use their best efforts to cause their respective
          officers, directors, employees, accountants, counsel,
          consultants, advisors and agents to hold, in confidence, unless
          compelled to disclose by judicial or administrative process or by
          other requirements of law, all confidential documents and
          information concerning the Business or ACLV furnished to Buyer or
          its Affiliates in connection with the transactions contemplated
          by this Agreement, except to the extent that such information can
          be shown to have been (i) previously known on a nonconfidential
          basis by Buyer, (ii) in the public domain through no fault of
          Buyer or (iii) later lawfully acquired by Buyer from sources
          other than ACLV; provided that Buyer may disclose such
          information to its officers, directors, employees, accountants,
          counsel, consultants, advisors and agents in connection with the
          transactions contemplated by this Agreement and to its financing
          sources in connection with obtaining the financing for the
          transactions contemplated by this Agreement so long as such
          Persons are informed by Buyer of the confidential nature of such
          information and are directed by Buyer to treat such information
          confidentially.  The obligation of Buyer and its Affiliates to
          hold any such information in confidence shall be satisfied if
          they exercise the same care with respect to such information as
          they would to preserve the confidentiality of their own similar
          information.  If this Agreement is terminated, Buyer and its
          Affiliates will, and will use their best efforts to cause their
          respective officers, directors, employees, accountants, counsel,
          consultants, advisors and agents to, destroy or deliver to ACLV,
          upon request, all documents and other materials, and all copies
          thereof, obtained by Buyer or its Affiliates or on their behalf
          from ACLV in connection with this Agreement that are subject to
          such confidence.

          8.02.  Access.  On and after the Closing Date, Buyer will afford
          promptly to ACLV and its agents reasonable access to its
          properties, books, records, employees and auditors to the extent
          necessary to permit ACLV to determine any matter relating to its
          rights and obligations hereunder or to any period ending on or
          before the Closing Date; provided that any such access by ACLV
          shall not unreasonably interfere with the conduct of the business
          of Buyer. 
          8.03.Margin Sharing Fee.  The Buyer shall pay to ACLV a margin
          sharing fee (the  Fee ) based on the annual Gross Margin (as
          defined below) of the Net Sales (as defined below) by Buyer of
          the Designated Products (as defined below).  The term of the Fee
          shall continue until August 30, 2006.  The Fee shall be 25% of
          the Gross Margin for Designated Products sold during the period
          commencing September 1, 1996.
                                         -31-
<PAGE>


           Gross Margin  shall be defined as Net Sales, less the Cost of
          Goods Sold of the Designated Products.   Net Sales  and  Cost of
          Goods Sold  shall be determined on the same basis as is presently
          utilized by ACLV on the date hereof.

           Designated Products  shall have the meaning set forth in a side
          letter agreement of even date herewith.

          Components of Designated Products (such as valves, pumps,
          compressors, vessels and closures, etc.) specifically developed
          under the Designated Project, as set forth in a side letter
          agreement of even date herewith, will become the property of the
          Buyer, and sales of such components other than as part of the
          Designated Products will not be subject to the Fee.

          The business or technology developed under the Designated Project
          may not be sold or licensed by the Buyer without the consent of
          ACLV (which consent shall not be unreasonably withheld) unless
          transferred as part of a sale of all or substantially all of the
          business of the Buyer.  If the Designated Customer terminates the
          Designated Agreement, the Fee shall also simultaneously
          terminate.  If the Buyer substantially abandons the Designated
          Project, then rights to this business or technology shall revert
          to ACLV for no consideration.

          Payment of the Fee shall be due and payable on a quarterly basis
          within forty-five (45) days of the end of each fiscal quarter of
          the Buyer based on Buyer invoices paid in the prior quarter by
          the purchaser of the Designated Products.  ACLV shall have the
          right at its expense to conduct an audit of the sales of
          Designated Products and Gross Margin through an independent
          auditor.

          In addition to the foregoing, Buyer shall pay to ACLV a one-time
          fee of One Million Dollars ($1,000,000) in cash within thirty
          (30) days of Buyer achieving $30 million of gross sales of
          Designated Products on a cumulative basis commencing with the
          Closing Date.

          8.04.  Liability Sharing Payment.Upon final resolution (whether
          by settlement, dismissal, judgment without further appeal, or
          resolution of appeal) of the lawsuit captioned  Leroy Andrews v.
          Autoclave Engineers, Inc. et al. as disclosed  on Schedule 3.12,
          Buyer shall pay to ACLV, in cash, the amount (if any) by which
          $250,000 exceeds Buyer s expenses and liabilities actually
          incurred and paid out-of-pocket and not reimbursed to Buyer by
          any applicable insurance or other recovery in connection with
          such lawsuits.

          8.05.  Claims Release.Buyer hereby unconditionally and fully
          releases ACLV and its Affiliates, and their respective officers,
          directors, agents and representatives from any and all claims and
          demands of any nature whatsoever, whether made at law or in
          equity, relating to the process by which the Business was offered
          and sold to Buyer, including, without limitation, any claim of
          unfair dealing or breach of any purported duty to conduct a fair
          auction.

          8.06.  Guarantee Release.Buyer and ACLV shall use their best
          efforts to obtain as soon as practicable a release, in form and
          substance satisfactory to ACLV, of ACLV s guarantee disclosed on
          Schedule 3.13(a)(ix).03.  Buyer shall indemnify and hold harmless
          ACLV and its Affiliates for any Loss arising or resulting from
          the above-described guarantee from and after the Closing Date.

          best efforts to take, or cause to be taken, all actions and to
          do, or cause to be done, all things necessary or desirable under
          applicable laws and regulations to consummate the transactions
          contemplated by this Agreement.  ACLV and Buyer each agree to
          execute and deliver such other documents, certificates,
          agreements and other writings and to take such other actions as
          may be necessary or desirable in order to consummate or implement
          expeditiously the transactions contemplated by this Agreement and
          to vest in Buyer good and marketable title to the Purchased
          Assets.

                    (b)  ACLV hereby constitutes and appoints, effective as
          of the Closing Date, Buyer and its successors and assigns as the
          true and lawful attorney of ACLV with full power of substitution
          in the name of Buyer or in the name of ACLV, but for the benefit
          of Buyer (i) to collect for the account of Buyer any items of
          Purchased Assets and (ii) to institute and prosecute all
          proceedings which Buyer may in its sole discretion deem proper in
          order to assert or enforce any right, title or interest in, to or
          under the Purchased Assets, and to defend or compromise any and
          all actions, suits or proceedings in respect of the Purchased
          Assets.  Buyer shall be entitled to retain for its account any
          amounts collected pursuant to the foregoing powers, including any
          amounts payable as interest in respect thereof.

               9.02.  Certain Filings.  ACLV and Buyer shall cooperate with
          one another (a) in determining whether any action by or in
          respect of, or filing with, any governmental body, agency,
          official or authority is required, or any actions, consents,
          approvals or waivers are required to be obtained from parties to
          any material contracts, in connection with the consummation of
          the transactions contemplated by this Agreement and (b) in taking
          such actions or making any such filings, furnishing information
          required in connection therewith and seeking timely to obtain any
          such actions, consents, approvals or waivers.

               9.03.  Public Announcements.  The parties agree to consult
          with each other before issuing any press release or making any
          public statement with respect to this Agreement or the
          transactions contemplated hereby and, except as may be required

                              SURVIVAL; INDEMNIFICATION
               11.01.  Survival.  The covenants, agreements,
          representations and warranties of the parties hereto contained in
          this Agreement or in any certificate or other writing delivered
          pursuant hereto or in connection herewith shall survive the
          Closing until the first anniversary of the Closing Date or:
          (i) in the case of Section 7.04, Section 8.03 and Section 8.04,
          for the respective periods set forth therein; (ii) in the case of
          Sections 8.01 and 8.06, indefinitely; and (iii) in the case of
          the covenants, agreements, representations and warranties
          contained in Articles V or VI, until expiration of the applicable
          statutory period of limitations (giving effect to any waiver,
          mitigation or extension thereof), if later.  Notwithstanding the
          preceding sentence, any covenant, agreement, representation or
          warranty in respect of which indemnity may be sought under
          Sections 11.02 or 11.03 shall survive the time at which it would
          otherwise terminate pursuant to the preceding sentence, if notice
          with specificity of the inaccuracy or breach thereof giving rise
          to such right to indemnity shall have been given to the party
          against whom such indemnity may be sought prior to such time. 
          Notwithstanding the foregoing, the covenants, agreements,
          representations and warranties of the parties hereto contained in
          Section 3.22 and Section 7.07 shall survive the Closing.

               11.02.  Indemnification.  (a) ACLV hereby indemnifies Buyer
          and its Affiliates against and agrees to hold each of them
          harmless from any and all damage, loss, liability and expense
          (including, without limitation, reasonable expenses of
          investigation and reasonable attorneys' fees and expenses in
          connection with any action, suit or proceeding but excluding lost
          profits and incidental, special and consequential damages), net
          of any Tax benefit actually realized or insurance proceeds
          received (collectively, "Loss"), incurred or suffered by Buyer or
          any of its Affiliates arising out of any misrepresentation or
          breach of warranty, covenant or agreement made or to be performed
          by ACLV pursuant to this Agreement that was unknown to Buyer at
          the Closing, provided that (i) ACLV shall not be liable for any
          individual Loss of less than $10,000  under this Section 11.02(a)
          unless the aggregate amount of all such Losses exceeds $100,000
          and then only to the extent of such excess and (ii) ACLV's
          maximum liability under this Section 11.02(a) shall not exceed
          $1,000,000.  The limitations in the provisos at (i) and (ii) of
          this Section 11.02(a) shall not apply to losses arising under
          Section 3.22 and Section 7.07.

                    (b)  Buyer hereby indemnifies ACLV and its Affiliates
          against and agrees to hold each of them harmless from any and all
          Loss incurred or suffered by ACLV or any of its Affiliates
          arising out of any misrepresentation or breach of warranty,
          covenant or agreement made or to be performed by the Buyer
          pursuant to this Agreement.

               11.03.  Procedures; No Waiver; Exclusivity.  (a) The party
          seeking indemnification under Section 11.02 (the "Indemnified
          Party") agrees to give prompt notice to the party against whom
          indemnity is sought (the "Indemnifying Party") of the assertion
          of any claim, or the commencement of any suit, action or
          proceeding in respect of which indemnity may be sought under such
          Section.  The Indemnifying Party may, and at the request of the
          Indemnified Party shall, participate in and control the defense
          of any such third party suit, action or proceeding at its own
          expense.  The Indemnifying Party shall not be liable under
          Section 11.02 for any settlement effected without its consent of
          any claim, litigation or proceeding in respect of which indemnity
          may be sought hereunder.

                    (b)  After the Closing, Section 11.02  will provide the
          exclusive remedy for any misrepresentation, breach of warranty,
          covenant or other agreement (other than those contained in
          Sections 7.04, 8.01, 7.07, 8.03 and 8.04) or other claim arising
          out of this Agreement or the transactions contemplated hereby.

                                     TERMINATION

               12.01.  Grounds for Termination.  This Agreement may be
          terminated at any time prior to the Closing:

                    (i)  by mutual written agreement of ACLV and Buyer;

                    (ii) by either ACLV or Buyer if the Closing shall not
          have been consummated on or before September 30, 1995; or

                    (iii)     by either ACLV or Buyer if consummation of
          the transactions contemplated hereby would violate any
          nonappealable final order, decree or judgment of any court or
          governmental body having competent jurisdiction.

               The party desiring to terminate this Agreement pursuant to
          clauses (ii) or (iii) shall give notice of such termination to
          the other party.

               12.02.  Effect of Termination.  If this Agreement is
          terminated as permitted by Section 12.01, such termination shall
          be without liability of either party (or any shareholder,
          director, officer, employee, agent, consultant or representative
          of such party) to the other  party to this Agreement; provided
          that if such termination shall result from the willful failure of
          either party to fulfill a condition to the performance of the
          obligations of the other party or to perform a covenant of this
          Agreement or from a willful breach by either party to this
          Agreement, such party shall be fully liable for any and all Loss
          incurred or suffered by the other party as a result of such
          failure or breach.  The provisions of Sections 8.01 and 13.03 
          shall survive any termination hereof pursuant to Section 12.01.

          deliver to Buyer all of the right, title and interest of ACLV in,
          to and under the Purchased Assets; provided that no sale,
          transfer, assignment or delivery shall be made of any material
          portion of any of the Contracts or Permits if an attempted sale,
          assignment, transfer or delivery, without the consent of a third
          party, would constitute a breach or other contravention thereof
          or in any way adversely affect the rights of Buyer or ACLV
          thereunder.

                    (b)  Buyer does hereby accept all the right, title and
          interest of ACLV in, to and under all of the Purchased Assets

          perform and discharge promptly and fully when due all of the
          Assumed Liabilities and to perform all of the obligations of ACLV
          to be performed under the Contracts and the Designated Agreement.

               2.   This Agreement shall be construed in accordance with
          and governed by the laws of the Commonwealth of Pennsylvania.

               3.   This Agreement may be executed in one or more
          counterparts, each of which shall be deemed to be an original,
          but all of which together shall constitute one and the same
          instrument.

          Section 4      Notice of Meetings

                     Written notice of every meeting of the shareholders

          entitled to vote at the meeting, at least ten (10) days prior to
          the day named for the meeting.  Such notice shall be given either
          personally or by sending a copy thereof through the mail or by
          telegram, charges prepaid, to each shareholder at his address
          appearing on the books of the Company or supplied by him to the
          Company for the purpose of notice.  Such notice shall specify the
          place, day and hour of the meeting, and, in the case of a special
          meeting, the purpose of the meeting and the general nature of the
          business to be transacted.  If mailed, such notice shall be
          deemed to have been delivered when deposited in the United States
          mail in a sealed envelope addressed to the shareholder at his
          address as it appears on the records of the Company, with postage
          thereon prepaid.

          Section 5      Closing of Transfer Books, Fixing of Record Date

                     The Board of Directors of the Company may close its
          stock transfer books for a period not exceeding fifty (50) but
          not less than ten (10) days prior to the date of any meeting of
          shareholders, or the date for the payment of any dividend or for
          the allotment of any rights or the date when any exchange or any
          reclassification of shares shall be effective; or in lieu
          thereof, may fix in advance, a date, not exceeding fifty (50) but
          not less than ten (10) days prior to the date of any meeting of
          shareholders or to the date for the payment of any dividend or
          for the allotment of rights, or to the date when any exchange or

          for the determination of shareholders entitled to notice of, or

          to vote at, such meeting, or shareholders entitled to receive
          payment of any such dividend or to receive any such allotment of
          rights, or to exercise rights in respect of any exchange or
          reclassification of shares; and the shareholders of record on
          such date shall be the shareholders entitled to notice of and to
          vote at, such meeting, or to receive payment of such dividend or
          to receive such allotment of rights, or to exercise such rights
          in the event of an exchange or reclassification of shares, as the
          case may be.  If the transfer books are not closed and no record
          date is fixed by the Board of Directors, the date on which notice
          of the meeting is mailed shall be deemed to be the record date
          for the determination of shareholders entitled to vote at such
          meeting.  Transferees of shares which are transferred after the
          record date shall not be entitled to notice or to vote at such
          meeting.

          Section 6      Waiver of Notice

                     A waiver of notice in writing signed by the person or
          persons entitled to such notice, whether before or after the time
          stated therein, shall be deemed equivalent to the giving of such
          notice.  Attendance of a person either in person or by proxy at
          any meeting shall constitute a waiver of notice of such meeting,
          except where such person attends a meeting for the express
          purpose of objecting to the transaction of any business because
          the meeting was not lawfully called or convened.

          Section 7      Quorum

                     The presence in person or by proxy of the holders of a
          majority of the outstanding shares entitled to vote at the
          shareholders' meeting shall constitute a quorum.  The
          shareholders present at a duly organized meeting can continue to
          do business until adjournment, notwithstanding the withdrawal of
          the holders of enough shares to leave less than a quorum.  If a
          meeting cannot be organized because a quorum has not attended,
          those present may adjourn the meeting to such time and place as
          they may determine, but, in the case of any meeting called for
          the election of directors, those who attend the second of such
          adjourned meetings, although less than a quorum, shall
          nevertheless constitute a quorum for the purpose of electing
          directors.

          Section 8      Adjournments of Meetings

                     Adjournment or adjournments of any annual or special
          meeting of the shareholders may be taken, but any meeting at
          which directors are to be elected shall be adjourned only from
          day to day until such directors have been elected.

                                     ARTICLE VII

                 Indemnification of Directors, Officers and Employees


          Section 1      Right to Indemnification

                     Except as prohibited by law, every director and
          officer of the Company shall be entitled as of right to be
          indemnified by the Company against all expenses, liability and
          loss (including without limitation, attorney's fees, judgments,
          fines, taxes, penalties and amounts paid in settlement) paid or
          incurred by such person in connection with any actual or
          threatened claim, action, suit or proceeding, civil, criminal,
          administrative, investigative or other, whether brought by or in
          the right of the Company or otherwise, in which he or she may be
          involved, as a party or otherwise, by reason of such person being
          or having been a director or officer of the Company or by reason
          of the fact such person is or was serving at the request of the
          Company as a director, officer, employee, fiduciary or other
          representative of another corporation, partnership, joint
          venture, trust, employee benefit plan or other entity (such
          claim, action, suit or proceeding hereinafter being referred to
          as an "Action"); provided, that no such right of indemnification
          shall exist with respect to an Action brought by an Indemnitee
          (as hereinafter defined) against the Company except as provided
          in the last sentence of this Section 1.  Persons who are not
          directors or officers of the Company may be similarly indemnified
          in respect of service to the Company or to another such entity at
          the request of the Company to the extent the Board of Directors
          at any time denominates any of such persons as entitled to the
          benefits of this Article.  As used in this Article, "Indemnitee"
          shall include each director and officer of the Company and each
          other person denominated by the Board of Directors as entitled to
          the benefits of this Article.  An Indemnitee shall be entitled to
          be indemnified pursuant to this Section 1 for expenses incurred
          in connection with any Action brought by such Indemnitee against
          the Company only if the Action is a claim for indemnity or
          expenses under Section 3 of this Article or otherwise and either
          (i) the Indemnitee is successful in whole or in part in the
          Action for which expenses are claimed or (ii) the indemnification
          for expenses is included in a settlement of the Action or is
          awarded by a court.

          Section 2      Right to Advancement of Expenses

                     Every Indemnitee shall be entitled as of right to have
          his or her expenses in any Action (other than an Action brought
          by such Indemnitee against the Company) paid in advance by the
          Company prior to final disposition of such Action, subject to any
          obligation which may be imposed by law or by provision in the
          Articles or By-laws of the Company, agreement or otherwise to
          reimburse the Company in certain events.

          Section 3      Right of Indemnitee to Initiate Action

                     If a written claim under Section 1 or Section 2 of
          this Article is not paid in full by the Company within thirty
          days after such claim has been received by the Company, the
          Indemnitee may at any time thereafter initiate an Action against
          the Company to recover the unpaid amount of the claim and, if
          successful in whole or in part, the Indemnitee shall also be
          entitled to be paid the expenses of prosecuting such Action.  It
          shall be a defense to any Action to recover a claim under Section
          1 of this Article that the Indemnitee's conduct was such that
          under Pennsylvania law the Corporation is prohibited from
          indemnifying the Indemnitee for the amount claimed, but the
          burden of proving such defense shall be on the Company.  Neither
          the failure of the Company (including its Board of Directors,
          independent legal counsel and its shareholders) to have made a
          determination prior to the commencement of such Action that
          indemnification of the Indemnitee is proper in the circumstances,
          nor an actual determination by the Company (including its Board
          of Directors, independent legal counsel or its shareholders) that
          the Indemnitee's conduct was such that indemnification is
          prohibited by law, shall be a defense to such Action or create a
          presumption that the Indemnitee's conduct was such that
          indemnification is prohibited by law.  The only defense to any
          such Action to receive payment of expenses in advance under
          Section 2 of this Article shall be failure to make an undertaking
          to reimburse if such an undertaking is required by law or by
          provision in the Articles or By-laws of the Company, agreement or
          otherwise.

          Section 4      Insurance and Funding

                     The Company may purchase and maintain insurance to
          protect itself and any person eligible to be indemnified
          hereunder against any expense, liability or loss asserted or
          incurred by such person in connection with any Action, whether or
          not the Company would have the power to indemnify such person
          against such expense, liability or loss by law or under the
          provisions of this Article.  The Company may create a trust fund,
          grant a security interest, cause a letter of credit to be issued
          or use other means (whether or not similar to the foregoing) to
          ensure the payment of such sums as may become necessary to effect
          indemnification as provided herein.

          Section 5      Non-Exclusivity; Nature and Extent of Rights

                     The rights of indemnification and advancement of
          expenses provided for this Article (i) shall not be deemed
          exclusive of any other rights, either now existing or hereafter
          created, to which any Indemnitee may be entitled under the
          Articles or By-laws of the Company, any agreement, any vote of
          shareholders or directors or otherwise, (ii) shall be deemed to
          create contractual rights in favor of each Indemnitee, (iii)
          shall continue as to each person who has ceased to have the
          status pursuant to which he or she was entitled or was
          denominated as entitled to indemnification hereunder and shall
          inure to the benefit of the heirs and legal representatives of
          each Indemnitee and (iv) shall be applicable to Actions commenced
          after the adoption hereof, whether arising from acts or omissions
          occurring before or after the adoption hereof.  The rights of
          indemnification provided in this Article may not be amended or
          repealed so as to limit in any way the indemnification or the
          right to advancement of expenses provided for herein with respect
          to any acts or omissions occurring prior to the adoption of such
          amendment or repeal.

          Section 6      Effective Date

                     This Article shall apply to every Action other than an
          Action filed prior to January 27, 1987, except that it shall not
          apply to the extent that Pennsylvania law prohibits its
          application to any breach of performance of duty or any failure
          of performance of duty by an Indemnitee occurring prior to
          January 27, 1987.



                                     ARTICLE VIII

                                      Amendments


          Section 1      Amendments to By-Laws

                     These By-laws may be altered or amended by a vote of a
          majority of the members of the Board of Directors at any regular
          or special meeting duly convened after notice of that purpose;
          subject, however, to the power of the shareholders to change or
          repeal the By-laws at any annual or special meeting duly convened
          after notice for that purpose.
