                                     PART I

ITEM 1.  BUSINESS

     KRUG International Corp., an Ohio corporation organized in June 1959, and
its subsidiaries (sometimes collectively called the "Corporation") operate
primarily in three business segments: Life Sciences and Engineering, Leisure
Marine and Housewares. Information concerning the revenues, operating profit
and identifiable assets of the three business segments for the fiscal years
ended March 31, 1997, 1996 and 1995 is set forth at Note M of the Notes to
Consolidated Financial Statements of the Corporation, which is incorporated
herein by this reference.

     The Corporation's objective is to increase shareholder value by the
investment in and management of businesses which offer growth opportunities.
The Corporation evaluates each of its operating companies for growth potential
and seeks opportunities, including acquisitions and divestitures, for the
profitable employment and realization of capital.

CERTAIN CAUTIONARY STATEMENTS

     This document contains certain forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995 including,
without limitation, statements regarding the Corporation's contracts and
backlog, its objectives and the outlook for its business segments. See Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations for certain risks, uncertainties and other factors which could cause
actual results to differ materially from those anticipated.



                         LIFE SCIENCES AND ENGINEERING

     The Life Sciences and Engineering business ("LS&E") is comprised of the
Corporation's KRUG Life Sciences Inc. subsidiary, with operations in Houston
and San Antonio, Texas and the Technology/Scientific Services, Inc. subsidiary
in Dayton, Ohio.

KRUG LIFE SCIENCES INC. -- HOUSTON OPERATIONS

     KRUG Life Sciences has been conducting, pursuant to contracts with the
National Aeronautics and Space Administration ("NASA"), biomedical research,
technology development, and flight crew operations support at NASA's Lyndon B.
Johnson Space Center continuously since 1967. From the original work of
developing specialized cardiovascular monitoring instrumentation, the research
and development activities have expanded to encompass certain additional
scientific activities relating to man's capability and capacity to explore and
exploit the frontiers of space. Such activities include the conceptualization
and implementation of groundbased and in-flight medical experiments to develop
the health care and physiological deconditioning countermeasures required to
offset the microgravity of space and ensure the well-being and productivity of
the flight crews.

     Performance under such contracts includes the areas of neurosensory
physiology, cardiovascular physiology, musculoskeletal physiology, regulatory
systems physiology, electrophysiology, cell biology, biochemistry,
pharmacodynamics, remote health care, bioengineering, applications of knowledge
based systems and clinical laboratory operations. KRUG's work for the Johnson
Space Center is spread over a wide variety of agency programs, none of which
comprise more than 20% of the aggregate contracts. Some of the major areas of
work include support of shuttle flights and the joint Russian MIR space
ventures, shuttle extended duration mission research, manned flight research
and development, space station research and biotechnology research.






                                       1
<PAGE>   4

     In March 1991, KRUG Life Sciences began work on a $136 million, five year
contract with NASA, replacing the one which previously started in January 1987.
This contract expanded the support services provided to the Medical Sciences
Division at the Johnson Space Center. In April 1993, NASA modified the contract
and increased its value to $165 million. This modification covered the cost of
additional test equipment, supplies and services for the remaining three years
of the contract. In February 1996, this contract was extended for a nine-month
period to November 30, 1996 and has been further extended in connection with
the rebid and sole source awards of various portions of the contract work.

     On January 15, 1997, KRUG Life Sciences won the rebid of the medical
support and integration portion of its work for NASA and signed a new contract
with an expected value of approximately $82.1 million over five years,
including $33.8 million for years four and five, which may be awarded at the
option of NASA. On January 30, 1997, KRUG Life Sciences was awarded by NASA, on
a sole source basis, a $21.6 million contract for the continuation of the
design, development, test and evaluation of flight hardware for the shuttle and
space station through December 31, 1998. In June 1997, KRUG Life Sciences
submitted its bid for a five year biotechnology processing contract covering
certain work it presently performs. NASA has indicated that it will award a
contract for such work to KRUG Life Sciences on a sole source basis effective
July 1, 1997; however, until a contract is executed, there can be no assurance
that such award will be forthcoming or as to the scope, term or amount of such
work.

KRUG LIFE SCIENCES INC. -- SAN ANTONIO OPERATIONS

     KRUG Life Sciences also provides professional research support services to
the United States Air Force ("USAF") under a contract which expires in November
1997 and is presently being rebid. Such services include research into human
tolerance to gravitational forces generated by rapid onset and increasing
acceleration. As advances in aircraft development lead to increases in speed
and mobility, this research becomes increasingly more important. Engineering
programs include the design and production of variable profile breathing
simulators, therapeutic oxygen manifold systems and other similar devices. KRUG
Life Sciences also does repair, maintenance and calibration of sophisticated
ground and airborne electronics equipment, and has provided such services on a
limited basis to commercial customers in the San Antonio area. The backlog
remaining on the USAF contract at March 31, 1997 was approximately $2.4
million.

TECHNOLOGY/SCIENTIFIC SERVICES, INC.

     Technology/Scientific Services provides a wide variety of engineering and
technical support services in various on-site governmental research and
experimental programs under contracts with the U.S. Air Force which expire from
September 1997 through September 2001. Current activities are principally in
support of laboratories at Wright-Patterson Air Force Base and involve computer
networking using fiber optics, satellite communications, aircraft structural
and environmental testing, microelectronics, fabrication techniques for
composite materials and aircraft vulnerability investigations. In August 1996,
Technology/Scientific Services was awarded a new contract for equipment
calibration at the Wright Laboratory, Wright-Patterson Air Force Base. The
contract consists of a base period beginning August 1, 1996 plus four one year
options through September 30, 2000. The contract value with the options is
approximately $5 million.

GENERAL AND OUTLOOK

     In its Life Sciences and Engineering Segment, the Corporation competes
with practically all the large and small aerospace companies, including small
local companies competing for services contracts. The areas of competition vary
from contract to contract but most contracts are price sensitive. Some business
has been obtained on a sole source basis, such as follow-on business, where a
unique capability or product has been developed and the limited market
precludes the development of a second source by the government.





                                       2
<PAGE>   5
     The majority of the Corporation's Life Sciences and Engineering business
is with agencies of the U.S. Government and prime government contractors and,
as a result, is subject to possible termination for the convenience of the
government.

     The order backlog of the Life Sciences and Engineering Segment was $106.9
million at March 31, 1997 and $60.4 million at March 31, 1996. Approximately
35% of the backlog at March 31, 1997 is expected to result in revenue during
fiscal 1998. Further information relating to the Corporation's LS&E Segment
contracts is included in Item 7, Management's Discussion and Analysis of
Financial Condition and Results of Operations.

     Management believes that the current economic forces at work in the
government services market, including government budgetary limitations and
increased competition for government contracts, have caused a number of
companies to enter into business combinations and activities designed to make
them larger, stronger and more competitive, and that to maintain its
competitiveness in the areas in which it holds contracts, KRUG Life Sciences
needs to be part of such a larger organization. In April, 1997, the Corporation
engaged Quarterdeck Investment Partners, Inc., an investment bank which
provides advisory services to aerospace, defense and information technology
companies, to assist in evaluating strategic alternatives concerning the LS&E
Segment.

                                 LEISURE MARINE

     Sowester Limited ("Sowester"), a subsidiary of KRUG International (U.K.)
Ltd., is engaged in the Leisure Marine business. Sowester, located in the port
of Poole, Dorset, England, distributes sail and power boat equipment and
personal watercraft to the leisure marine market. Sowester's principal product
lines include: marine chandlery, boat fittings, equipment and clothing; Mercury
outboard engines; Mercury MerCruiser sterndrive and inboard engines; Sea Doo
personal watercraft; Morse controls, steering systems and controls for power
and sail boats; and diesel engines which provide auxiliary power for sailing
yachts. Sowester is the exclusive distributor of certain Mercury engineering
products in the United Kingdom and the Republic of Ireland under distribution
agreements effective through July 1, 1998.

     Sowester sells its products in two principal markets -- boat manufacturers
and marine retailers -- through a network of over 100 sales and service
dealers. The marine products business is seasonal, with the highest sales
occurring in spring and summer. Order backlog is not a factor in the Leisure
Marine Segment since virtually all orders are shipped within days of receipt.

OUTLOOK

     The leisure marine business conducted by Sowester is specialized and
requires substantial industry-specific knowledge and skills. Management
believes the leisure marine business in the U.K. and Europe is moving toward a
consolidation phase likely to be dominated by and rewarding larger companies.
Such changes would likely affect the structural nature of marine distribution
as conducted by Sowester. Accordingly, management has taken steps to refocus
Sowester on growth opportunities and management objectives which it believes
will be important in the future and, under appropriate circumstances, the
Corporation will consider a merger or other transaction if satisfied that the
opportunity would enhance Sowester's ability to adapt to future changes in the
market.

                                   HOUSEWARES


     Beldray Limited ("Beldray"), a subsidiary of KRUG International (U.K.)
Ltd., operates the Corporation's Housewares business. Beldray manufactures
consumer durable products sold under the "Beldray" name and, through its Hago
Products Ltd. subsidiary, which was acquired October 31, 1996, manufactures
child safety gates under the KiddiProofAE tradename. Beldray's products include
ironing tables and accessories, domestic aluminum ladders and work platforms,
garden equipment, shower screens, indoor and outdoor racks for drying clothes,
child safety gates, fire guards and industrial wire products such as fan blade
covers. These products are marketed through major retailers, wholesalers and
mail order companies to the housewares, do-it-yourself and garden markets.
Beldray is a long established name with significant recognition among the
buying public throughout the United Kingdom. The Housewares Segment's firm
order backlog is typically less than one month's sales.

OUTLOOK

     Over the last eighteen months, Beldray has expanded its product offerings
to include child safety gates and completed the acquisition of Hago Products
Ltd. Beldray has also taken steps to reorganize its manufacturing processes,
upgrade its information technology and strengthen its management team.
Management believes Beldray should further expand its product lines, continue
improving its manufacturing efficiencies and broaden its customer base and
geographic distribution with the objectives of maintaining and, possibly,
enhancing its competitive position. Management expects to continue its efforts
to grow Beldray through complementary or synergistic acquisitions.

                              GENERAL INFORMATION

     The Corporation owns a number of patents and patent applications but it is
not possible to estimate their value. None of the Corporation's present
business is materially dependent on any patents or patent applications.

     During the fiscal year ended March 31, 1997, revenues from agencies of the
U.S. Government were $49,808,000 or 45% of consolidated revenues. The
Housewares business had revenues from one customer of $11,913,000 or 10% of
consolidated revenues.

     As of June 13, 1997, the Corporation employed 449 persons in the United
States and 605 in the United Kingdom. The Corporation's Life Sciences and
Engineering Segment employs highly trained persons holding bachelors degrees,
advanced degrees and professional designations in one or more of the following
disciplines -- engineering, medicine, mathematics, physics and biology. None of
the Corporation's United States employees are represented by a union.

     Compliance with federal, state, and local laws regulating the discharge of
materials into the environment or otherwise relating to the protection of the
environment has had no material effect upon the capital expenditures, earnings,
and competitive position of the Corporation. To the best of management's
knowledge, the Corporation is in compliance with federal, state and local
environmental regulations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

RESULTS OF OPERATIONS

     The Corporation's fiscal 1997 revenues of $111.7 million increased by 17%
from fiscal 1996. Fiscal 1996 revenues increased by 4% from fiscal 1995. In
fiscal 1997, revenues in the U.S. were $50.0 million, and revenues in the U.K.
were $61.7 million.

     Fiscal 1997 U.K. revenues of $61.7 million, which comprise the Housewares
Segment and Leisure Marine Segment, increased by $10.2 million or 20%. The
Housewares Segment revenue increased by $6.6 million or 25%. Hago Products
Limited (Hago), which was purchased on October 31, 1996, added $4.4 million of
revenue to the Housewares Segment during the year and revenue of Beldray Ltd.
increased by $2.2 million. The favorable effect of currency translation
contributed $0.4 million of revenue to the Housewares Segment. All Houseware
Segment product groups had increased sales from last year, with laundry
products, child safety gates and wire airer sales having the largest increases.
The Corporation believes the sales increases were the result of increased
market share and, with respect to child safety gates, the introduction of new
products and acquisition of Hago. Fiscal 1997 revenues of the Leisure Marine
Segment increased by $3.6 million, or 14% over last year. Of this increase,
$0.4 million was due to the favorable effect of currency translation. Increased
sales of chandlery products, outboard and inboard engines, engine parts and Sea
Doo personal watercraft also contributed to the increase. The increase in
chandlery revenue was due to the introduction of new chandlery products and
increases in other products resulted from higher demand for leisure marine
products in the UK.

     Fiscal 1996 U. K. revenues of $51.5 million increased by $3.7 million for
an 8% increase from fiscal 1995. Of this increase, $3.3 million was due to
increased sales volume with the remainder due to favorable currency
translation. Fiscal 1996 Leisure Marine Segment revenues increased by $4.1
million to $25.0 million, of which $3.9 million was due to increased sales
volume. All Leisure Marine Segment product groups had increased revenues except
for inboard engines. Chandlery and Sea Doo personal watercraft sales increased
significantly due to new products and increased demand. Fiscal 1996 Housewares
Segment revenues decreased by $0.4 million to $26.5 million, of which $0.6
million was due to decreased volume partially offset by $0.2 million of
favorable foreign currency translation. Sales of laundry products, rotary
dryers and wire airers decreased during the year. Laundry sales decreased 3% in
fiscal 1996 due to consumers buying ironing tables with lower prices. Rotary
dryers and wire airer sales decreased as a result of losing a significant
customer. The decreases were partially offset by the introduction of child
safety gates during the year.

     Revenues for the U.S. Life Sciences and Engineering Segment (LS&E) were
$50.0 million in fiscal 1997, $44.3 million in fiscal 1996 and $44.0 million in
fiscal 1995. Increased labor services, material purchases and subcontract
effort provided under contracts to the National Aeronautics and Space
Administration's (NASA) Johnson Space Center and the U.S. Air Force resulted in
the increased revenues in fiscal 1997. In fiscal 1996, increased labor services
and subcontract support provided to NASA resulted in the increased revenues
from fiscal 1995.

     The LS&E Segment order backlog at March 31, 1997 was $106.9 million
compared to $60.4 million at March 31, 1996 and $89.1 million at March 31,
1995. In January 1997, KRUG Life Sciences Inc. (KLSI) was awarded a new
five-year contract by NASA's Johnson Space Center Medical Services Division
(JSCMD) with a contract value over five years of approximately $82.1 million,
including $33.8 million for option years four and five. Effective January 30,
1997, KLSI signed a new $21.6 million contract with NASA's JSCMD for the
continuation of the design, development, test and evaluation of flight hardware
for the shuttle and space station through December 31, 1998. In addition, KLSI
has submitted a bid and is negotiating another five year NASA contract on a
sole source basis for biotechnology processing services. In August 1996, the
LS&E Segment was awarded a new contract for equipment calibration at the Wright
Laboratory, Wright-Patterson Air Force Base. The contract consists of a base
period beginning August 1, 1996 plus four one-year options through September
30,






                                      10
<PAGE>   13

2000. The contract value with the options is approximately $5.0 million.
Backlog is not meaningful in the Leisure Marine and Housewares Segments due to
the short time between order placement and shipment.

     Gross profit (revenues less cost of goods sold) margins were 13.3%, 12.6%
and 13.7% in fiscal 1997, 1996 and 1995, respectively. The increase in gross
profit margin in fiscal 1997 was due to increased margins in the Housewares
Segment which increased to 10.8% from 7.1% in fiscal 1996, due primarily to
increased selling prices and lower raw materials costs. Gross profit margin of
the Leisure Marine Segment increased slightly in fiscal 1997 primarily as a
result of increased sales of higher margin products. The gross profit margin of
the LS&E Segment decreased during fiscal 1997 due to increased material
purchases and subcontract support services provided under contracts to NASA and
the U.S. Air Force on which margins were lower than on other LS&E Segment
revenues. The decrease in gross profit margin in fiscal 1996 was due to
decreased margins in the Housewares Segment. Depressed selling prices caused by
competitive market conditions and increased raw material costs for aluminum and
steel which were not fully recovered through higher selling prices were the
primary causes of the Housewares Segment margin decrease. The Leisure Marine
Segment gross profit margin increased slightly in fiscal 1996 as compared to
fiscal 1995 as a result of selling more higher margin products. The gross
margin of the LS&E Segment decreased slightly during fiscal 1996 because of
increased subcontract service on U.S. government contracts for which no
additional profit was received.

     Selling and administrative expenses were $9.4 million, $9.2 million and
$8.8 million in fiscal 1997, 1996 and 1995, respectively. The increase in
fiscal 1997 is attributable primarily to the acquisition of Hago on October 31,
1996 and increased Leisure Marine Segment sales volume, which increased selling
expenses. Such increases were partially offset by decreased U.K. pension
expense and lower U.S. Corporate expense. The increase in selling and
administrative expenses in fiscal 1996 as compared to fiscal 1995 was due to
increased expenses of the Leisure Marine Segment caused by increased sales
volume, increased U.K. pension expense and U.S. Corporate expense for the
retiring Chairman's new consulting agreement which replaced his prior pension
agreement.

     In September 1996, the Corporation closed its executive offices in Dayton,
Ohio and consolidated its headquarters activities with its primary operations
facility adjacent to the NASA Johnson Space Center in Houston, Texas. A
restructuring charge of $0.8 million was recorded for such office consolidation
during the quarter ended September 30, 1996. The charge consisted primarily of
estimated costs relating to severance for six employees and rent and other
costs related to the vacated offices in Dayton, Ohio. In the fourth quarter of
fiscal 1997, the Corporation sublet the vacated offices and, as a result,
recorded a credit to the restructuring charge of $0.27 million.

     Interest expense decreased by $0.1 million in fiscal 1997 due to lower
average debt levels in both the U.S. and U.K. as compared to fiscal 1996.
Interest expense decreased by $0.2 million in fiscal 1996 compared to fiscal
1995 due to decreased levels of debt in both the U.K. and U.S. and slightly
decreased U.K. and U.S. interest rates.

     The effective income tax rate was 34.7% for fiscal 1997, 38.2% for fiscal
1996 and 31.0% for fiscal 1995. The effective tax rate for fiscal 1997 was
slightly higher than the statutory U.S. tax rate due to certain non-deductible
U.K. expenses partially offset by deductible U.K. pension amounts higher than
pension expense. The effective tax rate for fiscal 1996 was higher than the
statutory U.S. tax rate due to U.K. pension expense in excess of deductible
amounts, amortization of intangibles and other non-deductible expenses in the
U.K.




                                      11
<PAGE>   14


     Earnings from continuing operations were $2.6 million in fiscal 1997, an
increase of $1.4 million from fiscal 1996. The increase was due to profits
earned in the Housewares Segment for fiscal 1997 (versus losses in fiscal
1996), and increased sales and gross profit by the Leisure Marine Segment.
Earnings from continuing operations were $1.2 million in fiscal 1996, a
decrease of $0.8 million from fiscal 1995. The decrease was due to losses
incurred by the Housewares Segment in fiscal 1996 which were greater than the
increase in Leisure Marine Segment profits, and the absence of significant
other income items which were $0.5 million in fiscal 1995.

DISCONTINUED OPERATIONS

     In fiscal 1989, the Corporation discontinued the operations of its
Industrial Segment and subsequently disposed of substantially all related net
assets. However, obligations remain relating to leased property in Knoxville,
Tennessee, leased property in Toronto, Canada, and product liability claims for
products sold prior to the disposal. During the year ended March 31, 1997, the
Corporation recorded a charge of $0.5 million (net of a tax benefit of $0.2
million) to increase the provision for losses from such discontinued
operations. The increase was due to additional repair and maintenance costs
relating to the Knoxville property, decreased sublease income from the
Knoxville property, increased insurance costs related to product liability
claims and the loss of future sublease income caused by the bankruptcy filing
of a tenant in the Toronto facility.

LIQUIDITY AND CAPITAL RESOURCES

     Under the Corporation's revolving credit facility with a U.S. business
credit corporation, the Corporation had a loan outstanding of $ 3.8 million at
March 31, 1997. Availability under the revolving credit facility is based upon
the amount of billed and unbilled U.S. accounts receivable and is limited to a
maximum of $10.0 million. The credit facility expires March 15, 2000. Under the
agreement, the Corporation had additional borrowing capacity of $1.6 million
available at March 31, 1997. At March 31, 1997, the Corporation also had a $1.7
million mortgage loan outstanding on its Dayton, Ohio real property. The
mortgage loan was provided by five U.S. banks and matures on March 31, 1998.
The Corporation's U.K. subsidiaries had two term loans outstanding totaling
$5.6 million at March 31, 1997. The loans require quarterly principal payments
and mature in fiscal 2005. In addition, the Corporation has a U.K. line of
credit with $4.1 million available of which $1.2 million was used at March 31,
1997. The Corporation's various debt agreements contain affirmative and
negative covenants, including financial covenants relating to cash flow,
operating profit and limitations on cash dividends, additional debt and capital
expenditures. The Corporation believes it has adequate financing in both the
U.S. and U.K. to support its current level of operations.

     The Corporation generated $3.0 million, $2.5 million and $1.2 million from
operating activities for fiscal 1997, 1996 and 1995, respectively. The $0.5
million increase in cash generated from operating activities in fiscal 1997
compared to fiscal 1996 was due primarily to increased profit in the United
Kingdom and utilization of tax prepayments in the U.K., offset somewhat by
increased U.K. inventory levels, increased prepaid expenses and other assets
and increased net cash used in U.S. discontinued operations. The $1.3 million
increase in cash generated from operating activities in fiscal 1996 compared to
fiscal 1995 was due primarily to cash generated from decreased inventory levels
in the U.K. and decreased cash used by discontinued operations.

     During fiscal 1997 the Corporation's U.K. Housewares subsidiary expended
approximately $1.8 million for the purchase of Hago Products Ltd. Expenditures
for property, plant and equipment in fiscal 1997, 1996 and 1995 were $0.6
million, $0.3 million and $0.4 million, respectively. The capital expenditures
for fiscal 1997 include $0.3 million of new equipment for Leisure Marine
distribution activities while other capital expenditures for fiscal 1997 and
for fiscal 1996 and 1995 represent normal replacement expenditures. At March
31, 1997, there were no significant capital commitments.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Shareholders of
    KRUG International Corp.
Houston, Texas

We have audited the accompanying consolidated balance sheets of KRUG
International Corp. and Subsidiaries (the "Corporation") as of March 31, 1997
and 1996 and the related consolidated statements of earnings, shareholders'
equity and cash flows for each of the three years in the period ended March 31,
1997. These financial statements are the responsibility of the Corporation's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of KRUG International Corp. and
Subsidiaries at March 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended March 31,
1997 in conformity with generally accepted accounting principles.

KRUG INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
FOR THE YEARS ENDED MARCH 31, 1997, 1996 AND 1995 
(ALL DOLLAR AMOUNTS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
- -------------------------------------------------------------------------------


A.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
      include the accounts of the Corporation and its domestic and foreign
      subsidiaries. All significant intercompany transactions and balances have
      been eliminated.

      REVENUE RECOGNITION - Revenues from cost reimbursement and time and
      material government contracts are recorded as costs are incurred and
      include estimated earned fees. Earned fees on contracts with fixed- fee
      provisions are based on the proportion that costs incurred to date bear
      to total estimated costs at completion. For contracts with award fee
      provisions, fees are based on semiannual performance evaluations.
      Revenues from fixed-price contracts are generally recognized using the
      percentage-of-completion method for financial accounting purposes. Claims
      for recovery of additional contract costs are recognized only to the
      extent that the recoverable amounts can be determined with reasonable
      certainty. Costs not recoverable upon completion of contracts are
      immediately charged against earnings.

      USE OF ESTIMATES - The preparation of financial statements in conformity
      with generally accepted accounting principles requires management to make
      estimates and assumptions that affect the reported amounts of assets and
      liabilities and disclosure of contingent assets and liabilities at the
      date of the financial statements and the reported amounts of revenues and
      expenses during the reporting period. Actual results could differ from
      those estimates.

      INVENTORIES - Inventories are valued at the lower of cost or market using
      the first-in first-out method.

      LONG-LIVED ASSETS - The Corporation adopted Statement of Financial
      Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of
      Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" effective
      April 1, 1996. Implementation of SFAS No. 121 had no impact on the
      consolidated financial statements.

      DEPRECIATION - Property, plant and equipment, including capital leases,
      is depreciated over its estimated useful life principally using the
      straight-line method.

      STOCK-BASED COMPENSATION - The Corporation measures compensation cost for
      stock options issued to employees using the intrinsic value based method
      of accounting prescribed by Accounting Principles Board Opinion No. 25,
      "Accounting for Stock Issued to Employees."

      NET EARNINGS PER COMMON AND COMMON EQUIVALENT SHARE - Net earnings per
      share is computed by dividing net earnings by the weighted average number
      of Common Shares outstanding during each period, adjusted for the
      dilutive effect, if any, of stock options and stock warrants.

      FOREIGN CURRENCY TRANSLATION - The assets and liabilities of the
      Corporation's wholly owned U.K. subsidiaries are translated using
      exchange rates in effect at the balance sheet date, and amounts for the
      consolidated statements of earnings are translated using average exchange
      rates for the period. Translation gains and losses are recorded in
      shareholders' equity and transaction gains and losses are included in the
      consolidated statement of earnings for the period.




                                      20
<PAGE>   23


      FINANCIAL INSTRUMENTS - The recorded values of cash and trade receivables
      and payables approximate fair values because of the relatively short
      maturity of these instruments. Similarly, the fair values of the
      Corporation's notes payable are estimated to approximate current values
      due to their relatively short maturity and interest rate characteristics.

      RECENT ACCOUNTING STANDARDS - In February 1997 SFAS No. 128, "Earnings
      per Share" was issued. The statement requires dual presentation of basic
      and diluted earnings per share ("EPS") on the face of the statement of
      earnings for entities with complex capital structures. SFAS No. 128 is
      effective for financial statements for periods after December 15, 1997,
      including interim periods. Implementation of this pronouncement is not
      expected to have a material effect on reported EPS.

B.    ACQUISITION OF HAGO PRODUCTS LTD.

      Effective October 31, 1996, the Corporation's U.K. housewares subsidiary
      purchased the outstanding common stock of Hago Products Ltd. ("Hago"), a
      U.K. manufacturer of child safety gates and fireguards, for approximately
      $1.8 million in cash. The acquisition was financed with internally
      available funds including borrowings under the U.K. line of credit.

      The acquisition was accounted for using the purchase method of
      accounting. Accordingly, the consolidated statements of earnings include
      the results of operations of Hago since the effective date of the
      acquisition. The information below presents combined results of
      operations on a pro-forma basis assuming the acquisition had occurred at
      the beginning of the respective period:

Net earnings (loss) per share                                0.36         (0.06)
</TABLE>

      The pro-forma amounts shown above include adjustments to reflect interest
      expense for acquisition-related debt and are not necessarily indicative
      of the consolidated results that would have occurred had the acquisition
      taken place on April 1, 1995; nor are they necessarily indicative of
      results that may occur in the future.

      The U.S. Revolving Credit Line is a revolving credit facility with a U.S.
      business credit corporation which provides up to $10 million. The credit
      facility expires March 15, 2000. Interest is payable monthly at the
      lender's base rate plus 2%, (10-1/2% at March 31, 1997). Availability
      under the facility is based upon the billed and unbilled accounts
      receivable of the Corporation's U.S. operations. At March 31, 1997,
      additional availability under the revolving credit facility was
      approximately $1.6 million. Under the terms of the credit facility, the
      Corporation is restricted from declaring or paying cash dividends without
      the consent of the lender and must comply with certain other restrictive
      and financial covenants.

      The U.S. Mortgage, which is due March 31, 1998, is collateralized by the
      Corporation's Dayton, Ohio real property, which is held for sale.
      Interest is payable monthly at the bank's base rate plus 2% (10 1/2% at
      March 31, 1997).

      Substantially all U.S. assets (except shares of foreign subsidiaries and
      all related assets) are pledged as collateral for the U.S. Revolving
      Credit Line and Mortgage.

      The U.K. Term Loans are two, ten-year term loans which commenced in July
      1995 with a U.K. bank. The loans have quarterly principal payments that
      total $164, plus interest, at the bank's base rate plus 1 1/2% (8 1/4% at
      March 31, 1997). Substantially all U.K. assets (except shares of the U.K.
      subsidiaries) are pledged as collateral for the U.K. Term Loans. The Term
      Loans include certain tangible net worth and cash flow requirements
      relating to the U.K. subsidiaries. The Corporation's Bank Borrowing is
      pursuant to a line of credit for the U.K. subsidiaries of which $2,938
      was unused at March 31, 1997. Interest is payable quarterly on the line
      of credit at the bank's base rate plus 1 1/2% (8 1/4% at March 31, 1997).

      Annual payments of long-term debt, including capital leases, for the next
      five years are as follows: 1998 - $2,922; 1999 - $961; 2000 - $4,558;
      2001 - $685 and 2002 - $674.

F.    SHAREHOLDERS' EQUITY

      STOCK OPTION PLANS - The Corporation has three stock option plans
      permitting the grant of options to purchase common shares to officers and
      key employees; namely, the 1985 Incentive Stock Option Plan, the 1985
      Incentive Stock Option Scheme for U.K. Employees and the 1995 Incentive
      Stock Option Plan. The 1985 U.K. Scheme has been administered as part of
      the 1985 Incentive Stock Option Plan. The authority to grant options
      under the 1985 Plan has expired; however, 30,320 options previously
      granted are still outstanding. Under the 1995 Plan, the grant of options
      to purchase up to 250,000 Common Shares is authorized through May 2005,
      and 91,000 options are outstanding. Option grants are made at the fair
      market values on the date of grant and expire three to ten years later.
      Vesting periods are determined by the Board of Directors but may not
      exceed ten years. On April 30, 1996, the Board of Directors approved the
      immediate vesting of all of the then outstanding stock options. Options
      granted during the year ended March 31, 1997 vest ratably over two years
      from November 1996.

      The weighted-average fair value at grant date for the options granted
      during the years ended March 31, 1997 and 1996 was $1.65 and $1.15,
      respectively. The fair value of each stock option grant was estimated
      using the Black-Scholes option pricing model with the following
      weighted-average assumptions used for grants during the years ended March
      31, 1997 and 1996, respectively; estimated volatility of 51% and 55%;
      risk-free interest rate of 6%; dividend yield of 0%; and an expected life
      of 2.5 years.

      No compensation costs have been recognized for the stock option plans
      since the exercise price of the options is not less than the grant date
      fair value. Had compensation costs been determined on the fair value
      based method consistent with SFAS No. 123, the Corporation's net earnings
      would have been $2,033 and $1,169 and net earnings per share would have
      been $0.39 and $0.23 for the years ended March 31, 1997 and 1996,
      respectively.

      1997 EMPLOYEE STOCK PURCHASE PLAN - The 1997 Employee Stock Purchase Plan
      was approved by the Board of Directors in November 1996. Each employee
      continuously employed through December 31, 1997 by KRUG International
      Corp. and KRUG Life Sciences Inc. is eligible to purchase up to 200
      Common Shares for 85% of the fair market value as determined based on the
      lower of the last sale price at January 2, 1997 or December 31, 1997.
      Payments for stock subscribed under the plan are being made

      by payroll deductions. An employee may voluntarily terminate
      participation in the Plan at any time prior to December 31, 1997 and
      receive a refund of payroll deductions plus interest thereon at 7% per
      annum. At March 31, 1997, a total of 19,152 common shares have been
      subscribed by participants under this plan.

      WARRANTS - The Corporation issued warrants to shareholders of record on
      December 23, 1995. For each five common shares held, the Corporation
      distributed one warrant which may be used to purchase one common share.
      The warrants entitle the holders to purchase, in the aggregate, 999,487
      common shares. The purchase price was $7.125 per share through January
      31, 1997, and is $8.625 from February 1, 1997 through their expiration on
      January 31, 1998. The Corporation may reduce the purchase price at any
      time.

      In October 1995 the Corporation agreed to issue warrants to two outside
      advisory firms to purchase a total of 125,000 common shares at $3.031 per
      share. In December 1996 the Corporation terminated the advisory
      agreements which included the cancellation of the warrant provisions.

      STOCK DIVIDENDS - A 10% stock dividend distributed by the Corporation in
      fiscal year 1995 has been reflected in the financial statements for all
      periods presented.

      At March 31, 1997, the Corporation has accumulated domestic net operating
      loss carryforwards (expiring in 2005 through 2009) of approximately

      Earnings from continuing operations before income taxes include $3,439,
      $1,312 and $1,962 in 1997, 1996 and 1995, respectively, of foreign
      earnings.

      Domestic income taxes have not been provided on undistributed earnings of
      the foreign subsidiaries aggregating $19,279 at March 31, 1997 because
      such amounts are considered to be permanently invested abroad.
      Determination of the amount of the unrecognized deferred tax liability
      for these undistributed earnings is not practicable.

      defined benefit retirement plans covering substantially all of its
      employees. Benefits are principally based on years of service and level
      of earnings. The Corporation funds the domestic plan, which is
      noncontributory, at a rate that meets or exceeds the minimum amounts
      required by ERISA. The Corporation funds monthly contributions to the
      foreign plans, which are contributory, based on actuarially determined
      rates.

      Effective February 28, 1997, the Corporation amended its domestic plan to
      freeze participant benefits and close the plan to new participants. As a
      result, the Corporation recognized a curtailment gain of $369 primarily
      due to the reduction of the projected benefit obligation. The domestic
      pension asset recorded on the balance sheet would be substantially
      unrecoverable in the event of plan termination due to taxes, including
      excise taxes, which would be payable upon reversion of any excess pension
      assets to the Corporation.

      The components of net pension expense for all plans, excluding the
curtailment gain, are as follows:

      The weighted-average discount rate used for the domestic plan was 7.5% in
      1997 through the curtailment date and 1996. The discount rate was changed
      to 7.0% after the curtailment. Where appropriate, the projected rate of
      compensation increases was 4.5% in 1997 and 1996 and the expected rate of
      return on plan assets was 8% in 1997 and 1996. Domestic plan assets are
      primarily invested in listed stocks and bonds and U.S. government
      obligations. Approximately 12% of the fair value of the assets at March
      31, 1997 comprised 146,000 Common Shares of the Corporation.

      The weighted-average discount rate used for the foreign plans was 9% in
      1997 and 1996. The projected rate of compensation increases was 7% in
      1997 and 1996, and the expected rate of return on plan assets was 9% in
      1997 and 1996. Foreign plan assets are invested in managed fund units in
      the United Kingdom.

      DEFINED CONTRIBUTION PLAN - The Corporation has a defined contribution
      plan pursuant to IRS Section 401(k) covering substantially all domestic
      employees. The Corporation's policy is to contribute a specified
      percentage of the employees' contribution as determined periodically by
      the Corporation. Plan expense was $200 in 1997, $169 in 1996 and $170 in
      1995.

J.    COMMITMENTS AND CONTINGENCIES

      LEASES - The Corporation leases various land, buildings and equipment
      (principally for the U.K. companies) under capital and operating lease
      obligations with noncancelable terms ranging from 1 to 18 years. Minimum
      lease commitments as of March 31, 1997 follow:

      At March 31, 1997 and 1996, buildings and equipment under capital leases
      of $2,481 and $2,750 (less accumulated depreciation of $1,109 and
      $1,629), respectively, are included in property, plant and equipment.
      Rent expense under operating leases was $1,171, $993 and $922 for the
      years ended March 31, 1997, 1996 and 1995, respectively.

      LITIGATION - The Corporation is a party to claims and litigation
      incidental to its business, as to which it is not currently possible to
      determine the ultimate liability, if any. Based on an evaluation of
      information currently available and consultation with legal counsel,
      management is of the opinion that such claims and litigation are not
      likely to have a material effect on the financial position or results of
      operations of the Corporation.

      CONSULTING AGREEMENTS - The Corporation entered into a consulting
      agreement with its former chairman in April 1997 and terminated its
      obligation to him under a previous founders agreement. The remaining
      obligation under the consulting agreement of $450 and $700 at March 31,
      1997 and 1996, respectively, is included in other accrued expenses in the
      consolidated balance sheets.

      GOVERNMENT CONTRACTS - Overhead rates for cost reimbursement and time and
      material billed to government contracts are subject to possible audit,
      adjustment and/or renegotiation. Management does not believe such matters
      will have a material effect on the consolidated financial statements.

K.    RESTRUCTURING CHARGE

      In September 1996 the Corporation closed its executive offices in Dayton,
      Ohio and consolidated its headquarters activities with its primary
      operations facility adjacent to the NASA Johnson Space Center in Houston,
      Texas. A restructuring charge of $800 was recorded for such office
      consolidation during the quarter ended September 30, 1996. The charge
      consisted primarily of estimated costs relating to severance for six
      employees and rent and other costs related to the vacated offices in
      Dayton, Ohio. In the fourth quarter of fiscal year 1997, the Corporation
      recorded a credit to the restructuring charge of $270 after successfully
      subleasing the vacated offices. At March 31, 1997, the accrued
      restructuring charge of $340 primarily relates to rent (net of expected
      sublease rental income) and other expenses payable through June 1999, the
      lease termination date.

L.    DISCONTINUED OPERATIONS

      In fiscal 1989, the Corporation discontinued the operations of its
      Industrial Segment and subsequently disposed of substantially all related
      net assets. However, obligations remain relating to a leased property in
      Knoxville, Tennessee, a leased property in Toronto, Canada, and product
      liability claims for products sold prior to the disposal.

      During the year ended March 31, 1997, the Corporation recorded a charge
      of $456 (net of a tax benefit of $235) to increase the provision for
      losses for such discontinued operations. The increase was due to
      additional repair and maintenance costs relating to the Knoxville
      property, decreased sublease income from the Knoxville property,
      increased insurance costs related to product liability claims and loss of
      future sublease income caused by the bankruptcy filing of a tenant in the
      Toronto facility.

      During the year ended March 31, 1997, the reserve for losses from
      discontinued operations increased by the $691 charge previously discussed
      and decreased by $1,192 for charges to the reserve, leaving a balance of
      $918 at March 31, 1997. During the year ended March 31, 1996, the reserve
      for losses from discontinued operations increased by $140 from asset
      sales and decreased by $781 for charges to the reserve, leaving a balance
      of $1,419 at March 31, 1996. During the year ended March 31, 1995, the
      reserve for losses from discontinued operations increased by $700 as a
      result of a settlement with the bankruptcy court related to a major
      tenant of the Knoxville leased property who filed bankruptcy in 1994 and
      decreased by $1,212 for charges to the reserve.

      The Corporation is directly or contingently liable for lease and other
      commitments related to property formerly used by its discontinued
      operations. Commitments, net of minimum sublease rentals expected to be
      received, are $335 in 1998 and $196 in 1999.

years in the period ended March 31, 1997, and have issued our report thereon
dated May 16, 1997 (included elsewhere in this Form 10-K). Our audits also

such consolidated financial statement schedules, when considered in relation to
the basic financial statements taken as a whole, present fairly in all material
respects the information set forth therein.

                                     - 12 -
<PAGE>   24





conditions hereinafter set forth, short-term advances to the Borrower Group
("Revolving Advances") on any Business Day during the period from the date
hereof to the Business Day preceding the Termination Date in aggregate amounts
not to exceed at any time outstanding for Revolving Advances by a Lender the
amount set forth opposite such Lender's name in Exhibit B under the caption
"Revolving Commitment" nor exceeding at any time for aggregate outstandings for
all Revolving Advances of the Lenders the lesser of (a) the amount which, when
added to the outstanding Term Loan balance, equals $15.0 million or (b) $2.5
million.  Within such limits, the Borrower Group may borrow, repay and reborrow
under this Section 2.2 provided, however, that any and all such Revolving
Advances will be available: (i) only to satisfy short-term cash needs which
arise to enable the Borrowers to fulfill requirements of specific contracts and
(ii) for periods of up to 90 days.  The Revolving Credit Banks will extend any
Revolving Advance for an additional period of time of up to 60 days if the
Borrowers provide written justification, satisfactory to the Administrative
Agent.  By way of example, but not in limitation thereon, a satisfactory
justification for an extension or a new borrowing would be the failure of
prompt receipt of payment by Borrowers from a party with whom a Borrower
contracted, which payment would have theretofore reimbursed Borrowers for a
contract expenditure funded by the Revolving Advance.  The Revolving Advances
will be evidenced by the Revolving Credit Note (a copy of which is set forth in
Exhibit C attached) payable to the order of the Administrative Agent on behalf
of the Revolving Credit Banks.  The Revolving Advances will bear interest and
will be payable in the manner set forth herein and in the Revolving Credit
Note, the terms of which are incorporated herein by reference.

                          2.2.2.         PROCEDURE FOR BORROWING.

                                        2.2.2.1.  NOTICE OF BORROWING. Whenever
the Borrowers desire to request any Revolving Advance, KRUG will give written
notice (or telephonic notice confirmed in writing) to the Administrative Agent
in the form of the attached Exhibit D ("Notice of Borrowing") no later than
10:00 a.m. (Philadelphia time) on a Business Day which is at least two Business
Days prior to the requested funding date.  Each Notice of Borrowing must
specify: (a) the requested funding date of the Revolving Advance (which must be
a Business Day); (b) the purpose of the requested Revolving Advance and (c) the
aggregate amount of the requested





                                     - 13 -
<PAGE>   25





Revolving Advance.  Each Notice of Borrowing will be accompanied by such
reports or documents as may reasonably be requested by the Administrative
Agent.  Each borrowing will be in an aggregate amount not less than $100,000
and increments of $50,000 in excess thereof.  The Administrative Agent will,
within 24 hours receipt thereof, furnish the Revolving Credit Banks with a copy
of each Notice of Borrowing.

                                        2.2.2.2.  REVOLVING ADVANCES.  Subject
to the terms and conditions of this Agreement the Revolving Credit Banks will
each make their ratable share of such funds requested in the Notice of
Borrowing available to the Administrative Agent on the funding date, by wire
transfer no later than 11:00 a.m.  (Philadelphia time), and the Administrative
Agent will credit all funds so received by it to KRUG's corporate account
maintained by the Administrative Agent on the Funding Date.

                                        2.2.2.3.  FAILURE TO FUND.  The failure
of any Revolving Credit Bank to make timely the Revolving Advance to be made by
it as part of any borrowing will not relieve it or any other Revolving Credit
Bank of its obligation, if any, hereunder to make its Revolving Advance.
However, no Revolving Credit Bank (nor the Administrative Agent) will be
responsible for the failure of any other Revolving Credit Bank to make a
Revolving Advance requested of such other Revolving Credit Bank.

              2.3.        INTEREST, PAYMENTS, COMPUTATIONS, FEES AND 
COLLECTIONS.

                          2.3.1.         INTEREST.  Unless an Event of Default
has occurred and is continuing, the Borrowers shall pay interest on the unpaid
principal amount of all Obligations of the Borrowers to the Lenders pursuant to
this Agreement from the respective dates on which such loans or Revolving
Advances are made, or Obligations incurred, until such principal amounts have
been repaid in full at a fluctuating annual rate equal to the Prime Rate plus:
(a) two percent (2%) when interest is being computed for any days when the
aggregate unpaid principal balance of all Obligations of the Borrowers to the
Lenders is $10,000,000 or more and (b) one and one-half percent (1 1/2%) at
such time as (i) the aggregate unpaid principal balance of all Obligations of
the Borrowers to the Lenders and (ii) the aggregate of all Revolving
Commitments is permanently less than $10,000,000.  The Prime Rate





                                     - 14 -
<PAGE>   26





means the rate of interest established and so designated by PNB from time to
time, as its prime rate (which may not necessarily be the lowest rate of
interest offered by PNB) with changes therein effective immediately upon
changes in said Prime Rate.

                          2.3.2.         INTEREST PAYMENT DATES.  All interest
accrued will be payable by the Borrowers in arrears (a) on December 1, 1991 and
on the first Business Day of each succeeding calendar month thereafter and (b)
upon the Termination Date.

                          2.3.3.         DEFAULT RATE.  Effective immediately
upon any Event of Default and for so long thereafter as such Event of Default
shall be continuing, both before and after the entry of judgment and/or both
before and after the commencement of a bankruptcy proceeding of any Borrower,
the principal balance of all Obligations then outstanding, and to the extent
permitted by applicable law, any interest payments on the Obligations not paid
when due, shall bear interest at the Default Rate which is equal to four
percent (4%) per annum plus the Prime Rate in effect from time to time.

                          2.3.4.         COMPUTATIONS.  All computations of
interest and of fees will be made by the Administrative Agent on the basis of a
year of 360 days, in each case for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such
interest or fees are payable.  Each determination by the Administrative Agent
of an interest rate hereunder will be conclusive and binding for all purposes,
absent manifest error.  Whenever any payment to be made by the Borrowers
hereunder or under the Notes will be stated to be due on a day other than a
Business Day, such payment will be made on the next succeeding Business Day,
and such extension of time will in such case be included in the computation of
payment of interest or fees, as the case may be.

                          2.3.5.         FACILITY FEES.  The Borrowers shall
pay the Administrative Agent, on behalf of the Revolving Credit Banks, a fee in
the amount of $30,000 per year as compensation to the Revolving Credit Banks
for extending the Revolving Commitment.  This fee shall be payable in the
amount of $7,500 quarterly in advance (a) upon execution of this Agreement

obligations of the Borrowers thereunder, including but not limited to
reasonable Attorneys' Fees and the costs and expenses of litigation, such costs

Administrative Agent.

              9.2.        REPRESENTATIONS AND WARRANTIES TO SURVIVE.  All
representations, warranties, covenants and agreements made by the Borrowers
herein and in the Security Documents will survive the execution and delivery of

any liability or obligation of, or claims asserted against the Lenders for
loss, damage, fines, penalties, claims or duty to clean-up or dispose of wastes

to the consummation of this transaction or as a result of any conveyance of
title to the Lenders by foreclosure, deed in lieu of foreclosure, or otherwise.
Each of the Borrowers agrees to remain fully liable and will indemnify and hold

on the part of the Administrative Agent or any Lender in exercising any right,
power or remedy hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right, power or remedy preclude any
other or further exercise thereof or the exercise of any other right, power or
remedy hereunder.  No waiver of any provision of this Agreement or any of the
Security Documents shall be effective unless the same shall be in writing and
signed by all of the Lenders, except as provided in Section 9.7 hereof.  The
remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

              9.5.        NOTICES.  All notices, demands, requests, consents or

              9.6.        SUCCESSORS AND ASSIGNS.  This Agreement will be
binding upon and inure to the benefit of the Borrowers and the Lenders and
their respective successors and assigns, provided, however, that none of the
Borrowers may assign this Agreement in whole or in part without the prior
written consent of the Administrative Agent and all of the Lenders and provided
further that no consent of any Borrower will be required to any assignment by
any Lender in whole or in part.

              9.7.        AMENDMENTS AND WAIVERS.  The provisions of this
Agreement may be modified or amended only by a written agreement entered into
by Borrowers and the Lenders and may be waived only by a written waiver signed
by the Administrative Agent on behalf of the Lenders.  Except for (a) waivers
of any payment default, (b) an increase in the amount of the Credit Facilities,
(c) a change or modification of any applicable or required: (i) interest rate;
(ii) fee; or (iii) repayment requirement, (d) release of Collateral, or (e) an
extension of the Termination Date, all of which require unanimous consent of
all Lenders, the provisions of this Agreement can be modified with the consent
of the Majority Lenders provided, however, that no waiver of an Event of
Default under Section 7.1.2 of this Agreement will be effective without the
prior written consent of Central Trust.  No such waiver, modification or
amendment shall extend to or affect any obligation not expressly waived,
modified or amended, or impair any right of the Lenders related to such
obligation.

              9.8.        ILLEGALITY.  If fulfillment of any provision hereof
or any transaction related hereto or of any provision of the Notes or the
Security Documents, at the time performance of such provision is due, involves
transcending the limit of validity prescribed by law, then ipso facto, the
obligation to be fulfilled will be reduced to the limit of such validity; and
if any clause or provisions herein contained other than the provisions hereof
pertaining to repayment of the Obligations operates or would prospectively
operate to invalidate this Agreement in whole or in part, then such clause or
provision only will be void, as though not herein contained, and the remainder
of this Agreement will remain operative and in full force and effect; and if
such provision pertains to repayment of the Obligations, then, at the option of
the Lenders, all of the Obligations will become immediately due and payable.

              9.9.        GENDER, ETC.  Whenever used herein, the singular
number will include the plural, the plural the singular and the use of the
masculine, feminine or neuter gender will include all genders.

              9.10.       HEADINGS.  The headings in this Agreement are for
convenience only and will not limit or otherwise affect any of the terms
hereof.

              9.11.       EXECUTION IN COUNTERPARTS.  This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed will be deemed to be an
original and all of which taken together will constitute one and the same
agreement.

              9.12.       REMEDIES CUMULATIVE.  No single or partial exercise
of any right or remedy by any of the Lenders will preclude any other or further
exercise thereof or the exercise of any other right or remedy by any Lender.
All remedies hereunder and in any instrument or document evidencing, securing,
guaranteeing or relating to any Obligation or now or hereafter existing at law
or in equity or by statute are cumulative and none of them will be exclusive of
the others or any other remedy.  All such rights and remedies may be exercised
separately, successively, concurrently, independently or cumulatively from time
to time and as often and in such order as each of the Lenders may deem
appropriate.

              9.13.       LIABILITY OF THE ADMINISTRATIVE AGENT AND LENDERS.
Except for gross negligence and willful misconduct, the Borrowers hereby agree
that the Administrative Agent and the Lenders will not be chargeable for any
negligence, mistake, act or omission of any accountant, examiner, agent or
attorney selected by the Administrative Agent or the Lenders in making
examinations, investigations or collections, or otherwise in protecting or
realizing upon any lien or security interest or any other interest in the
Collateral or other security for the Obligations.  In performing any of its
actions or duties under this Agreement, the Security Documents, the
Intercreditor Agreement or otherwise, the Borrowers hereby agree that the
Administrative Agent acts solely as Administrative Agent of the Lenders and
does not assume or have any obligation or duty toward or agency relationship
with or for any Borrower or Guarantor.

              9.14.       INTERCREDITOR AGREEMENT.  The provisions of the
Intercreditor Agreement are solely for the benefit of the Administrative Agent
and the Lenders, and may at any time or times by changed by the Lenders as they
may elect without necessity of notice to or consent or approval by any
Borrower, Guarantor or other Person (other than the Lenders); and none of the
Borrowers or Guarantors shall have any right to rely on or enforce any of the
provisions of the Intercreditor Agreement.  In performing its actions and
duties under the Intercreditor Agreement, the Credit Agreement or any of the
Security Documents, the Administrative Agent acts solely as Administrative
Agent of the Lenders and does not assume or have any obligation toward or
agency relationship with or for any Borrower or Guarantor.

              9.15.       INDEMNITY.  The Borrowers will release, indemnify,
defend and hold harmless the Administrative Agent, the Lenders, their
respective directors, officers, counsel and employees, from and against all
claims, demands, liabilities, judgments, losses, damages, costs and expenses,
joint or several (including all accounting fees and Attorneys' Fees reasonably
incurred), that any such indemnified party may incur arising under or by reason
of this Agreement, the Obligations, Security Documents, Disclosure Schedule or
Collateral, or any act hereunder or thereunder or with respect hereto or
thereto except the willful misconduct or gross negligence of such indemnified
party.  Without limiting the generality of the foregoing, the Borrowers agree
that if, after receipt by the Administrative Agent or any Lender of any payment
of all or any part of the Obligations, demand is made at





                                     - 43 -
<PAGE>   55





any time upon the Administrative Agent or any Lender for the repayment or
recovery of any amount or amounts received by it in payment or on account of
the Obligations and the Administrative Agent or the Lenders repay all or any
part of such amount or amounts by reason of any judgment, decree or order of
any court or administrative body, or by reason of any settlement or compromise
of any such demand, this Agreement will continue in full force and effect and
the Borrowers will be liable, and will indemnify, defend and hold harmless the
Administrative Agent and the Lenders for the amount or amounts so repaid.  The
provisions of this Section 9.15 will be and remain effective notwithstanding
any contrary action which may have been taken by any Borrower in reliance upon
such payment, and any such contrary action so taken will be without prejudice
to the Administrative Agent's or any Lender's rights under this Agreement and
will be deemed to have been conditioned upon such payment having become final
and irrevocable.  The provisions of this Section will survive the termination
of this Agreement.

              9.16.       CONTINUING AGREEMENT.  This Agreement is and is
intended to be a continuing Agreement and will remain in full force and effect
until the Obligations are finally and irrevocably paid in full and the Credit
Facilities are terminated.

              9.17.       NO THIRD PARTY BENEFICIARIES.  Nothing express or
implied herein is intended or will be construed to  confer upon or give any
Person, firm or corporation, other than the parties hereto, any right or remedy
hereunder or by reasons hereof.

              9.18.       NO PARTNERSHIP OR JOINT VENTURE.  Nothing contained
herein or in any of the agreements or transactions contemplated hereby is
intended or will be constructed to create any relationship other than as
expressly stated herein or therein and will not create any joint venture,
partnership or other relationship.

              9.19.       JOINT AND SEVERAL LIABILITY.  All covenants,
representations and obligations of the Borrowers in and under this Agreement
will be joint and several.

              9.20.       GOVERNING LAW AND JURISDICTION; WAIVER OF JURY TRIAL.
THIS AGREEMENT HAS BEEN EXECUTED, DELIVERED AND ACCEPTED AT AND WILL BE DEEMED

         AMENDMENT NO. 1 dated November 22, 1991 to CREDIT AGREEMENT dated as
of November 14, 1991 among KRUG INTERNATIONAL CORP., TECHNOLOGY/SCIENTIFIC
SERVICES, INC., KRUG LIFE SCIENCES, INC. (collectively, "Borrowers") and
SOCIETY BANK, NATIONAL ASSOCIATION, THE CENTRAL TRUST COMPANY, N.A., COMERICA
BANK, CORESTATES BANK, N.A., a national banking association which also conducts
business as Philadelphia National Bank and as CoreStates First Pennsylvania
Bank, and SECURITY PACIFIC NATIONAL BANK (collectively, "Lenders" and each
individually a "Lender") and CoreStates Bank, N.A. as Administrative Agent.

                                   ARTICLE I

                                   BACKGROUND

         The Borrowers, the Lenders and the Administrative Agent acknowledge
that:

         1.      On or about November 14,  1991, the parties entered into,
inter alia, a Credit Agreement.  The parties now wish to amend and supplement
the Credit Agreement to provide for a change in the definition of the term
"Excess Cash Flow".

                                   ARTICLE II

                                   AMENDMENT

         1.      The Credit Agreement is amended, effective as of November 22,
1991, by deleting paragraph 1.25 in its entirety and inserting, in its place,
the following:

                 "1.25.    "Excess Cash Flow" means, for a specific fiscal
year, the positive difference, if any, obtained from subtracting the positive
Projected Net Cash Flow (or zero (0) if Projected Net Cash Flow is negative)
for that fiscal year of KRUG and its Domestic Subsidiaries (as delivered to the
Administrative Agent in accordance with Section 5.6 of the Agreement) from the
Actual Net Cash Flow covering the  same fiscal year of KRUG and its Domestic
Subsidiaries (based on the financial statements delivered to the Administrative
Agent in accordance with Section 5.5 of the Agreement).    For the purposes
hereof, "Actual Net Cash Flow" means the sum of actual sources of cash
(excluding Revolving Advances) for the given year less (a) Net Mortgage
Proceeds, if any; (b)  as to the fiscal year ending March 31, 1992, the amount
due under Section 2.5.1(c); (c) as to the fiscal
<PAGE>   60





year ending March  31, 1993, the amount due under Section 2.5.1(d); and (d) the
sum of actual uses of cash for the given year.  For the purposes hereof,
"Projected Net Cash Flow" means the sum of projected sources of cash for the
given year less the sum of projected uses of cash for the given year."

<PAGE>   88


owing to the Administrative Agent and/or any or all of the Lenders, jointly or
severally, from the Debtor, now or hereafter arising under the Guarantee of
even date herewith made by the Debtor in favor of the Lenders (covering the
joint and several obligations of the Borrowers described therein), the Security
Documents described in the Guarantee and all charges, expenses, fees,
Attorneys' Fees and any other sums chargeable to the Guarantor under the
Guarantee, such Security Documents or other Obligations.

                     Notwithstanding anything contained herein to the contrary,
the Collateral does not include a pledge of the Capital Stock of KRUG
International (U.K.) Ltd.

                     Capitalized terms used herein and not otherwise defined in
this Security Agreement will have the meanings given those terms in the Credit
Agreement.

                     The Debtor further warrants to and agrees with the
Administrative Agent as follows:

            1.       PRESERVATION OF COLLATERAL.  The Debtor will keep the
Collateral in good order and repair at all times, will use same with reasonable
care and caution, except as permitted by this Security Agreement, will not part
with possession or ownership thereof nor lease or hire out same without the
written consent of the Administrative Agent, and will exhibit the same to the
Administrative Agent upon demand.  The Debtor will not use, or permit the
Collateral to be used, in violation of any federal, state, county or municipal
law or regulation or for any unlawful purpose whatsoever.

            2.       INSURANCE.  The Debtor will keep its insurable real and
personal property insured with responsible insurance companies against loss or
damage by fire, windstorm and other hazards which are commonly insured against
in an extended coverage endorsement in an amount equal to not less than 80% of
the insurable value thereof on a replacement cost basis and also maintain
public liability insurance in a reasonable amount.  In addition, the Debtor
will maintain extended liability insurance covering its operations in at least
such amounts and covering at least such risks as are usually carried by
companies engaged in similar businesses and owning similar properties in the
same general areas in which the Debtor operates or owns such properties with
responsible insurance companies reasonably satisfactory to the Administrative
Agent.  Notwithstanding the foregoing, property insurance will at all times





                                    - 3 -
<PAGE>   89





be in an amount so that the Debtor will not be deemed a "co-insurer" under any
co-insurance provisions of such policies.  All such insurance policies will
name the Administrative Agent, where applicable, as lender loss payee under a
lender's loss payable endorsement satisfactory to the Administrative Agent and,
if required by the Administrative Agent, as an additional insured.  All such
policies will provide that thirty (30) days' prior written notice must be given
to the Administrative Agent if such policy is altered or cancelled.  Schedules
of all insurance of the Debtor will be submitted to the Administrative Agent
upon request.  Such schedules will contain a description of the risks covered,
the amounts of insurance carried on each risk, the name of the insurer and the
cost of such insurance to the Debtor.  Such schedules will be supplemented by
the Debtor from time to time promptly to reflect any change in insurance
coverage.  The Debtor will deliver to the Administrative Agent certificates
representing such insurance policies from time to time when requested by the
Administrative Agent.  Subject to the rights of any mortgagee of the Debtor's
real property, all amounts payable in settlement of insurance losses may be
applied, at the Debtor's option, on the Obligations, or used to repair, replace
or restore the Collateral.

            3.       PAYMENT OF EXPENSES BY THE ADMINISTRATIVE AGENT.  At its
sole option, and after the Debtor's failure to do so after reasonable notice,
the Administrative Agent may discharge taxes, liens, security interests or such
other encumbrances as may attach to the Collateral, may pay for required
insurance on the Collateral and may pay for the maintenance and preservation of
the Collateral, as determined by the Administrative Agent to be necessary.  The
Debtor will reimburse the Administrative Agent on demand for any payment so
made or any expense incurred by the Administrative Agent pursuant to the
foregoing authorization, and the Collateral also will secure any advances or
payments so made or expenses so incurred by the Administrative Agent.

            4.       GOVERNMENT CONTRACTS.  The Debtor shall immediately notify
the Administrative Agent if any of the Debtor's Receivables in excess of
$100,000 arise out of contracts with the United States or any department,
agency or instrumentality thereof, furnish the Administrative Agent with copies
of each such contract and execute and deliver any instruments and take any
steps required by the Administrative Agent in order that all moneys due and to
become due under any such contract shall be assigned to the Administrative
Agent and notice given (consistent with paragraph 7 hereof) under the Federal
Assignment of Claims Act (including executing and





                                    - 4 -
<PAGE>   90



delivering to the Administrative Agent Assignments in the form of Exhibit N to
the Credit Agreement).

            5.       INFORMATION.  The Debtor will furnish to the
Administrative Agent from time to time if and as requested current lists of the
Collateral; will continue to make on the books of the Debtor appropriate
entries evidencing the assignment of book accounts to the Administrative Agent
and will mark chattel paper and non-negotiable instruments to evidence the
assignment thereof to the Administrative Agent; and, if and when requested by
the Administrative Agent from time to time, will furnish to it copies of all
purchase orders, contracts, inventory lists, billings, shipping orders,
correspondence and other instruments or writings in any way evidencing or
relating to the Collateral or the proceeds thereof.

            6.       SALE OF INVENTORY AND EQUIPMENT.  As long as no Event of
Default exists and no Acceleration or Termination (each as hereinafter defined)
has occurred, the Debtor will have the right to process and sell the Inventory
in the regular course of its business at customary prices (but in no event may
the Debtor transfer any Inventory in satisfaction of any debt), to dispose of
Equipment in the regular course of its business provided the Equipment disposed
of is (a) either obsolete in Debtor's business or (b) replaced with other
Equipment, which replacement Equipment will be Collateral and subject to this
Agreement and subject to the Credit Agreement.  The Debtor will give the
Administrative Agent notice of any returned Inventory with a total value
exceeding $25,000 per return.

            7.       COLLECTIONS; SETOFF.  Unless and until there is an
Acceleration or a Termination (each as hereinafter defined), the Debtor will
collect all of the Receivables and General Intangibles and whenever the Debtor
receives any payment on any of the Receivables or General Intangibles or any
other collections, receipts or proceeds of any kind it will promptly deposit
the same in the bank account(s) with the Lenders, which deposits will be
governed by the Credit Agreement.  In the event of an Acceleration or a
Termination then: (a) the Debtor authorizes any of the Lenders or the
Administrative Agent, or any employees thereof, to endorse the name of the
Debtor upon any checks, negotiable instruments or other items received in
payment of any of the Receivables or other Collateral and to do all of the
things necessary to reduce the same to cash; (b) the Debtor authorizes any of
the Lenders or the Administrative Agent at any time thereafter without notice
to





                                    - 5 -
<PAGE>   91





appropriate and apply any balances, credits, deposits or accounts or money of
the Debtor in its possession, custody or control to the payment of the
Obligations, all of which may at all times be held and treated as additional
Collateral.

            8.       NOTIFICATION OF ACCOUNT DEBTORS.  In the event of an
Acceleration or a Termination (a) the Administrative Agent at any time
thereafter and without notice to the Debtor may notify any persons who are
indebted to the Debtor with respect to any Receivables or General Intangibles
of the assignment thereof to the Administrative Agent and may direct such
account debtors to make payment directly to the Administrative Agent of the
amounts due; (b) at the request of the Administrative Agent, the Debtor will
direct any persons who are indebted to the Debtor with respect to any
Receivables or General Intangibles to make payment directly to the
Administrative Agent and (c) the Administrative Agent shall be authorized to
give receipts to such account debtors and other obligors for any such payments
and the account debtors and other obligors will be protected in making such
payments to the Administrative Agent.

            9.       REPRESENTATIONS AND WARRANTIES.  The Debtor represents and
warrants to the Administrative Agent that:  (a) except as set forth in the
Disclosure Schedule, the Debtor has not made any prior sale, pledge,
encumbrance, assignment or other disposition of any of the Collateral and the
same is free from all encumbrances and rights of setoff of any kind; (b) except
as provided herein or in the Credit Agreement, the Debtor will not hereafter
without the prior written consent of the Administrative Agent sell, pledge,
encumber, assign or otherwise dispose of any of the Collateral or permit any
right of setoff, lien or security interest to exist thereon except to the
Administrative Agent; (c) the Debtor will defend the Collateral against all
claims and demands of all persons at any time claiming the same or any interest
therein; (d) the Debtor will deliver to the Administrative Agent any chattel
paper evidencing the Receivables; (e) each General Intangible is genuine and
enforceable in accordance with its terms and the Debtor will defend the same
against all claims, demands, setoffs and counterclaims at any time asserted;
(f) except as to unbilled Receivables, at the time any of the Receivables
becomes subject to this Security Agreement, such Receivable will be a good and
valid account representing a bona fide sale of goods or services by the Debtor
and such goods will have been shipped to the respective account debtors or the
services will have been performed for the respective account debtors; (g) as to
unbilled Receivables, at the





                                    - 6 -
<PAGE>   92





time any of the Receivables becomes subject to this Security Agreement, such
Receivable will represent partial performance by the Debtor, in an amount
determined by the Debtor based on Debtor's usual percentage of completion
accounting practices, under a bona fide contract or order for which the Debtor
has the right to be paid at some future time after full and satisfactory
performance under the contract or order; and (h) the Debtor will notify the
Administrative Agent promptly in the event of the refusal of any account debtor
to accept, or of the return of, any goods which are then subject to any such
Receivable with a total value exceeding $25,000 per refusal or return and of
the bankruptcy or insolvency of any account debtor and of claims asserted for
credit, allowance, adjustment, setoff, defense or counterclaim with a total
value exceeding $25,000 per claim.

            10.      PLACE OF BUSINESS.  The Debtor (a) now keeps and, except
as permitted in the Credit Agreement, will continue to keep the Collateral and
the books and records concerning the Collateral at its places of business as
shown in the Disclosure Schedule, and (b) represents that it has no places of
business other than those set forth in the Disclosure Schedule.

            11.      FINANCING STATEMENTS; DOCUMENTS.  At the request of the
Administrative Agent, the Debtor will join with the Administrative Agent in
executing one or more financing statements pursuant to the Uniform Commercial
Code in form satisfactory to the Administrative Agent and will pay the cost of
filing all financing, continuation and termination statements in all public
offices where filing is deemed necessary or desirable by the Administrative
Agent.  The Debtor will execute and deliver to the Administrative Agent from
time to time such supplemental assignments or other instruments as the
Administrative Agent may require for the purpose of confirming the
Administrative Agent's interest in the Collateral, including but not limited to
any and all notices and assignments of receivables under contracts with
Governmental Authorities.  The Debtor hereby authorizes the Administrative
Agent to execute and file on behalf of the Debtor all financing statements and
documents deemed necessary or appropriate to perfect the Administrative Agent's
interest in the Collateral.

            12.      DEBTOR'S CONSENT.  The Debtor consents, with respect to
the Receivables or any General Intangibles, upon the occurrence of any Event of
Default and Acceleration or Termination, to all extensions or postponements of
time of payment thereof or any other indulgences in connection therewith, to
the acceptance of partial





                                    - 7 -
<PAGE>   93





payments thereon and to the settlement, compromise and adjustment thereof, all
in such manner and at such time or times as the Administrative Agent deems
advisable.

            13.      DEFAULT.

                     13.1      Upon the occurrence of any Event of Default as
defined in the Credit Agreement (herein referred to as an "Event of Default")
and a determination by the Majority Lenders under Section 7.2 of the Credit
Agreement to declare the Obligations to be due and payable ("Acceleration") or
to declare the Revolving Commitment to be terminated ("Termination"), the
Administrative Agent is authorized in its discretion to declare any or all of
the Obligations immediately due and payable without demand or notice to the
Debtor (except such notice as may be required by the Credit Agreement) and may
exercise any one or more of the rights and remedies granted pursuant to this
Security Agreement, the Credit Agreement and/or applicable law (including those
given to a secured party under the Pennsylvania version of the Uniform
Commercial Code, as it may be amended from time to time), including but not
limited to the right upon default and after an Acceleration or a Termination to
take possession and sell, lease or otherwise dispose of the Collateral and, at
its option, operate, use or exercise any rights of ownership pertaining to the
Collateral as the Administrative Agent deems necessary to preserve the value
and receive the benefits of the Collateral.  Upon the occurrence of an Event of
Default and an Acceleration or a Termination, the Administrative Agent may, so
far as the Debtor can give authority therefore, enter upon any premises on
which the Collateral or any part thereof may be situated and take possession of
and remove the same therefrom.  The Administrative Agent may require the Debtor
to make the Collateral available to the Administrative Agent at a place to be
designated by the Administrative Agent that is reasonably convenient to both
parties.  The Debtor waives all claims for damages by reason of any seizure,
repossession, retention, use or sale of the Collateral under the terms of this
Security Agreement.

                     13.2      The net proceeds arising from the disposition of
the Collateral after deducting expenses incurred by the Administrative Agent
will be applied to the Obligations in the order determined by the
Administrative Agent.  If any excess remains after the discharge of all of the
Obligations, the same will be paid to the Debtor.  If after exhausting all of
the





                                    - 8 -
<PAGE>   94





Collateral, there should be a deficiency, the Debtor will be liable therefor to
the Administrative Agent.

                     13.3      Whenever notice is required by law to be sent by
the Administrative Agent to the Debtor of any sale, lease or other disposition
of the Collateral, five days written notice sent by certified mail to the
Debtor's address set forth in accordance with Section 16.2 below will be
reasonable.

                     13.4      If any demand is made at any time upon the
Administrative Agent for the repayment or recovery of any amount received by it
in payment or on account of any of the Obligations and if the Administrative
Agent repays all or any part of such amount, the Debtor will be and remain
liable for the amounts so repaid or recovered to the same extent as if never
originally received by the Administrative Agent.

            14.      RIGHTS OF THE ADMINISTRATIVE AGENT; POWER OF ATTORNEY.
The Debtor hereby irrevocably constitutes and appoints the Administrative Agent
and any officer thereof, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of the Debtor or in its name, from time to time in the Administrative
Agent's discretion, for the purpose of carrying out the terms of this Security
Agreement, upon the occurrence of any Event of Default and an Acceleration or a
Termination, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Security Agreement and, without limiting the generality of the
foregoing, the Debtor hereby gives the Administrative Agent the power and
right, on behalf of the Debtor, after any Event of Default and an Acceleration
or a Termination, and without notice (except such notice as may be required by
the Credit Agreement) to or assent by the Debtor, to do the following:

                     14.1      to receive payment of, endorse, and receipt for,
any and all monies, claims and other amounts due and to become due at any time
in respect of or arising out of the Collateral;

                     14.2      to commence and prosecute any suits, actions or
proceeding at law or in equity in any court of competent jurisdiction to
collect any of the Collateral and to enforce any other right in respect of the
Collateral;





                                    - 9 -
<PAGE>   95





                     14.3      to settle, compromise or adjust any suit, action
or proceeding described above, and, in connection therewith, to give such
discharges or releases as the Administrative Agent may deem appropriate; and

                     14.4      generally to sell, transfer, pledge, make any
agreement with respect to or otherwise deal with any of the Collateral as fully
and completely as though the Administrative Agent were the absolute owner
thereof for all purposes, and to do, at the Administrative Agent's option, at
any time, or from time to time, all acts and things which the Administrative
Agent deems necessary to protect or preserve the Collateral and the
Administrative Agent's security interest and rights therein in order to effect
the intent of this Security Agreement, all as fully and effectively as the
Debtor might do.

The Debtor hereby ratifies all that such attorneys shall lawfully do or cause
to be done by virtue hereof.  This power of attorney is a power coupled with an
interest, will be irrevocable and shall terminate only upon payment in full of
the Obligations and the termination of this Security Agreement.  The powers
conferred upon the Administrative Agent hereunder are solely to protect the
Administrative Agent's interests in the Collateral and will not impose any duty
upon it to exercise any such powers.  The Administrative Agent will have no
obligation to preserve any rights of any third parties in the Collateral.  The
Administrative Agent will be accountable only for amounts that it actually
receives as a result of the exercise of such powers, and neither it nor any of
its officers, directors, employees or Administrative Agents will be responsible
to the Debtor for any action taken or omitted to be taken in good faith or in
reliance on the advice of counsel except for its own gross negligence and
willful misconduct.

            15.      GEORGIA AGREEMENT.  The Debtor represents, warrants and
covenants that (a) the Debtor will observe and perform all covenants and
conditions to be performed by the Debtor under the Georgia Agreement; (b) the
Debtor will, at its sole cost and expense, enforce, short of termination of the
Georgia Agreement, the observance of every covenant and condition of the
Georgia Agreement to be observed and performed by the other parties to the
Georgia Agreement; (c) the Debtor will appear in and defend any action growing
out of, or in any manner connected with, the Georgia Agreement or the
obligations or liabilities of the Debtor thereunder; and (d) the Debtor will
not without the prior written consent of the Administrative Agent terminate,
alter, amend or





                                   - 10 -
<PAGE>   96





modify the Georgia Agreement, release any party liable thereunder or waive or
release any party to the Georgia Agreement from the observance of any material
covenant or condition to be observed or performed by such party under the terms
of the Georgia Agreement or from any liability on account of any warranty given
by such party therein.

            16.      GENERAL.

                     16.1      WAIVER.  No delay or omission on the part of the
Administrative Agent or any of the Lenders to exercise any right or power
arising from any Event of Default will impair any such right or power or be
considered a waiver of any such right or power or a waiver of any such Event of
Default or in acquiescence therein nor will the action or non-action of the
Administrative Agent or any of the Lenders in case of such Event of Default
impair any right or power arising as a result thereof.

                     16.2      NOTICES.  All notices, demands, requests,
consents, approvals and other communications required or permitted hereunder
will be in writing and will be conclusively deemed to have been received by a
party hereto and to be effective if delivered personally to such party, or sent
by telex, telecopy (followed by written confirmation) or other telegraphic
means, or by overnight courier service, or by certified or registered mail,
return receipt requested, postage prepaid, addressed to such party at the
address set forth in the Guarantee or to such other address as any party may
give to the other pursuant to the Guarantee in writing for such purpose.  All
such communications, if personally delivered, will be conclusively deemed to
have been received by a party hereto and to be effective when so delivered, or
if sent by telex, telecopy or telegraphic means, on the day on which
transmitted, or if sent by courier service, on the day after deposit thereof
with such service, or if sent by certified or registered mail, on the third
business day after the day on which deposited in the mail.

                     16.3      SUCCESSORS AND ASSIGNS.  This Security Agreement
will be binding upon and inure to the benefit of the Debtor and the
Administrative Agent, as Administrative Agent for the Lenders, and their
respective successors and assigns; provided, however, that the Debtor may not
assign this Security Agreement in whole or in part without prior written
consent of the Administrative Agent.

                     16.4      MODIFICATIONS.  No modification or waiver of any
provision of this Security Agreement nor consent to any departure by the Debtor
therefrom, will in any event be effective unless the same is in writing and
specifically refers to this Security Agreement, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice to or demand on the Debtor in any case will entitle the
Debtor to any other or further notice or demand in the same, similar or other
circumstance.

                     16.5      ILLEGALITY.  If fulfillment of any provision
hereof or any transaction related hereto or of any provision of this Security
Agreement, at the time performance of such provision is due, involves
transcending the limit of validity prescribed by law, then ipso facto, the
obligation to be fulfilled will be reduced to the limit of such validity; and
if any clause or provisions herein contained other than the provisions hereof
pertaining to repayment of the Obligations operates or would prospectively
operate to invalidate this Security Agreement in whole or in part, then such
clause or provision only will be void, as though not herein contained, and the
remainder of this Security Agreement will remain operative and in full force
and effect; and if such provision pertains to repayment of the Obligations,
then, at the option of the Administrative Agent, all of the Obligations of the
Debtor to the Administrative Agent will become immediately due and payable.

                     16.6      GENDER, ETC.  Whenever used herein, the singular
number will include the plural, the plural the singular and the use of the
masculine, feminine or neuter gender will include all genders.

                     16.7      HEADINGS.  The headings in this Security
Agreement are for convenience only and will not limit or otherwise affect any
of the terms hereof.

                     16.8       LIABILITY OF THE ADMINISTRATIVE AGENT.  The
Debtor hereby agrees that the Administrative Agent will not be chargeable for
any negligence, mistake, act or omission of any accountant, examiner,
Administrative Agent or attorney employed by the Administrative Agent in making
examinations, investigations or collections, or otherwise in protecting or
realizing upon any lien or security interest or any other interest in the
Collateral.  The Administrative Agent will not be obligated to perform or
discharge any obligation or duty of the Debtor concerning any of the Collateral
and the acceptance of this assignment and grant of a security interest in the
Collateral does not constitute an assumption by the Administrative Agent of any
obligation or duty.  The Debtor will indemnify and hold the Administrative
Agent harmless against (a) all liabilities, losses and damages that the
Administrative Agent may incur under the Collateral or under or by reason of
this Security Agreement and (b) all claims and demands whatsoever that may be
asserted against the Administrative Agent by reason of this Security Agreement
or any act of the Administrative Agent under this Security Agreement or
concerning any of the





                                   - 13 -

Collateral, except where due to the willful misconduct or gross negligence of
the Administrative Agent.

                     16.9      GOVERNING LAW AND JURISDICTION; NO JURY TRIAL.
THIS SECURITY AGREEMENT HAS BEEN EXECUTED, DELIVERED AND ACCEPTED AT AND WILL
BE DEEMED TO HAVE BEEN MADE AT PHILADELPHIA, PENNSYLVANIA AND SHALL BE GOVERNED
IN ALL RESPECTS BY THE LAW OF THE COMMONWEALTH OF PENNSYLVANIA AND FOR ALL
PURPOSES SHALL BE CONSTRUED IN ACCORDANCE WITH SUCH LAW, EXCEPT TO THE EXTENT
THAT THE VALIDITY OR PERFECTION OF SECURITY INTERESTS IN ANY OF THE COLLATERAL

JURISDICTION SET FORTH ABOVE.  NOTHING CONTAINED HEREIN WILL AFFECT THE RIGHT
OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE PROCESS IN ANY MANNER
PERMITTED BY LAW OR PREVENT THE ADMINISTRATIVE AGENT OR ANY LENDER FROM
BRINGING ANY ACTION, ENFORCING ANY JUDGMENT OR EXERCISING ANY RIGHTS AGAINST
THE DEBTOR, OR AGAINST ANY SECURITY OR AGAINST ANY PROPERTY OF THE DEBTOR
WITHIN ANY OTHER JURISDICTION.  THE DEBTOR, THE LENDERS AND THE ADMINISTRATIVE

                                   ARTICLE I

                                   BACKGROUND

         The Debtor and the Administrative Agent acknowledge that:

         1.      In accordance with the terms of a Credit Agreement and other
Loan Documents (as defined in the Credit Agreement) dated as of November 14,
1991, the Debtor executed and delivered a Security Agreement, dated as of
November 14, 1991, to the Administrative Agent.

         2.      Certain modifications were made to the Credit Agreement
shortly before its execution and the Security Agreement should be amended to
address those modifications.

         3.      The Debtor now wishes to amend and supplement the Security
Agreement it issued on November 14, 1991 in order to address the
above-referenced modifications made to the Credit Agreement.

                                   ARTICLE II

                                   AMENDMENTS

         1.      The Security Agreement is amended by eliminating the language
in paragraph 6 thereof in its entirety and inserting, in its place, the
following:

                 "6.      SALE OF INVENTORY AND EQUIPMENT.  As long as no
Acceleration, Termination or Maturity (each as hereinafter defined) has
occurred, the Debtor will have the right to process and sell the Inventory in
the regular course of its business at customary prices (but in no event may the
Debtor transfer any Inventory in satisfaction of any debt), to dispose of
Equipment in the regular course of its business provided the Equipment disposed
of is (a) either obsolete in Debtor's business or (b) replaced with other
Equipment, which replacement Equipment will be Collateral and subject to this
Agreement and subject to the Credit Agreement.  The Debtor will give the
Administrative Agent notice of any returned Inventory with a total value
exceeding $25,000 per return."
<PAGE>   102
         2.      The Security Agreement is amended by eliminating the language
in paragraph 13.1 thereof in its entirety and inserting, in its place, the
following:

                 "13.1.  If (i) the Revolving Commitment is terminated in
accordance with Section 7.2(a) or Section 7.2(c) of the Credit Agreement (a
"Termination"), or (ii) all or any portion of the unpaid principal amount of
the Notes or Obligations is accelerated in accordance with Section 7.2(a) or
Section 7.2(c) of the Credit Agreement (an "Acceleration"), or (iii) any of
such Notes or Obligations are not paid at the Termination Date (as defined in
the Credit Agreement) (a "Maturity"), the Administrative Agent may exercise any
one or more of the rights and remedies granted pursuant to this Security
Agreement, the Credit Agreement and/or applicable law (including those given to
a secured party under the Pennsylvania Uniform Commercial Code, as it may be
amended from time to time), including but not limited to the right upon default
and after an Acceleration, a Termination or a Maturity to take possession and
sell, lease or otherwise dispose of the Collateral and, at its option, operate,
use or exercise any rights of ownership pertaining to the Collateral as the
Administrative Agent deems necessary to preserve the value and receive the
benefits of the Collateral.  Upon the occurrence of an Acceleration, a
Termination or a Maturity, the Administrative Agent may, so far as the Debtor
can give authority therefor, enter upon any premises on which the Collateral or
any part thereof may be situated and take possession and remove the same
therefrom.  The Administrative Agent may require the Debtor to make the
Collateral available to the Administrative Agent at a place to be designated by
the Administrative Agent that is reasonably convenient to both parties.  The
Debtor waives all claims for damages by reason of any seizure, repossession,
retention, use or sale of the Collateral under the terms of this Security
Agreement.  References in other paragraphs of this Security Agreement to
"Acceleration" shall mean an Acceleration or a Maturity."

         3.      The Security Agreement is amended by eliminating the language
in paragraph 14 thereof in its entirety (except as provided in paragraph 4
hereinbelow) and inserting, in its place, the following:

                 "14.      RIGHTS OF THE ADMINISTRATIVE AGENT; POWER OF
ATTORNEY.  The Debtor hereby irrevocably constitutes and appoints the
Administrative Agent and any officer thereof, with full power of substitution,
as its true and lawful attorney-in-fact with full irrevocable power and

discretion, for the purpose of carrying out the terms of this Security
Agreement, upon the occurrence of an Acceleration, a Termination or a Maturity,
to take any and all appropriate action and to execute any and all documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Security Agreement and, without limiting the generality of the foregoing,
the Debtor hereby gives the Administrative Agent the power and right, on behalf
of the Debtor, after an Acceleration, a Termination or a Maturity, and without
notice (except such notice as may be required by the Credit Agreement) to or
assent by the Debtor, to do the following:"

         4.      Notwithstanding anything to the contrary contained in
paragraph 3 hereinabove, paragraphs 14.1, 14.2, 14.3, 14.4 and the last
unnumbered paragraph which follows paragraph 14.4 of the Security Agreement

                                   ARTICLE I

                                   BACKGROUND

         The Debtor and the Administrative Agent acknowledge that:

         1.      In accordance with the terms of a Credit Agreement and other
Loan Documents (as defined in the Credit Agreement) dated as of November 14,
1991, the Debtor executed and delivered a Security Agreement, dated as of
November 14, 1991, to the Administrative Agent.

         2.      Certain modifications were made to the Credit Agreement
shortly before its execution and the Security Agreement should be amended to
address those modifications.

         3.      The Debtor now wishes to amend and supplement the Security
Agreement it issued on November 14, 1991 in order to address the
above-referenced modifications made to the Credit Agreement.

                                   ARTICLE II

                                   AMENDMENTS

         1.      The Security Agreement is amended by eliminating the language
in paragraph 6 thereof in its entirety and inserting, in its place, the
following:

                 "6.      SALE OF INVENTORY AND EQUIPMENT.  As long as no
Acceleration, Termination or Maturity (each as hereinafter defined) has
occurred, the Debtor will have the right to process and sell the Inventory in
the regular course of its business at customary prices (but in no event may the
Debtor transfer any Inventory in satisfaction of any debt), to dispose of
Equipment in the regular course of its business provided the Equipment disposed
of is (a) either obsolete in Debtor's business or (b) replaced with other
Equipment, which replacement Equipment will be Collateral and subject to this
Agreement and subject to the Credit Agreement.  The Debtor will give the
Administrative Agent notice of any returned Inventory with a total value
exceeding $25,000 per return."

         2.      The Security Agreement is amended by eliminating the language
in paragraph 13.1 thereof in its entirety and inserting, in its place, the
following:

                 "13.1.  If (i) the Revolving Commitment is terminated in
accordance with Section 7.2(a) or Section 7.2(c) of the Credit Agreement (a
"Termination"), or (ii) all or any portion of the unpaid principal amount of
the Notes or Obligations is accelerated in accordance with Section 7.2(a) or
Section 7.2(c) of the Credit Agreement (an "Acceleration"), or (iii) any of
such Notes or Obligations are not paid at the Termination Date (as defined in
the Credit Agreement) (a "Maturity"), the Administrative Agent may exercise any
one or more of the rights and remedies granted pursuant to this Security
Agreement, the Credit Agreement and/or applicable law (including those given to
a secured party under the Pennsylvania Uniform Commercial Code, as it may be
amended from time to time), including but not limited to the right upon default
and after an Acceleration, a Termination or a Maturity to take possession and
sell, lease or otherwise dispose of the Collateral and, at its option, operate,
use or exercise any rights of ownership pertaining to the Collateral as the
Administrative Agent deems necessary to preserve the value and receive the
benefits of the Collateral.  Upon the occurrence of an Acceleration, a
Termination or a Maturity, the Administrative Agent may, so far as the Debtor
can give authority therefor, enter upon any premises on which the Collateral or
any part thereof may be situated and take possession and remove the same
therefrom.  The Administrative Agent may require the Debtor to make the
Collateral available to the Administrative Agent at a place to be designated by
the Administrative Agent that is reasonably convenient to both parties.  The
Debtor waives all claims for damages by reason of any seizure, repossession,
retention, use or sale of the Collateral under the terms of this Security
Agreement.  References in other paragraphs of this Security Agreement to
"Acceleration" shall mean an Acceleration or a Maturity."

         3.      The Security Agreement is amended by eliminating the language
in paragraph 14 thereof in its entirety (except as provided in paragraph 4
hereinbelow) and inserting, in its place, the following:

                 "14.      RIGHTS OF THE ADMINISTRATIVE AGENT; POWER OF
ATTORNEY.  The Debtor hereby irrevocably constitutes and appoints the
Administrative Agent and any officer thereof, with full power of substitution,

Agreement, upon the occurrence of an Acceleration, a Termination or a Maturity,
to take any and all appropriate action and to execute any and all documents and

the Debtor hereby gives the Administrative Agent the power and right, on behalf
of the Debtor, after an Acceleration, a Termination or a Maturity, and without
notice (except such notice as may be required by the Credit Agreement) to or
assent by the Debtor, to do the following:"

         4.      Notwithstanding anything to the contrary contained in

unnumbered paragraph which follows paragraph 14.4 of the Security Agreement

                   REPRESENTATIONS, WARRANTIES AND COVENANTS

      The Mortgagor covenants, represents, warrants and agrees with the
Mortgagee as follows:

      3.1        TITLE.  The Mortgagor is the lawful owner of the Property;
title to the Property is vested in the Mortgagor and is free, clear and
unencumbered except for Permitted Liens (as defined in the Credit Agreement);
there has been no prior assignment of any of the Mortgagor's rights in the
Property; the Mortgagor has good right and full power to convey and encumber
the Property and to execute this Mortgage; the Mortgagor will make such further

      3.2        INDEBTEDNESS.  The Mortgagor will promptly pay, or cause to be
paid, the Indebtedness when due.

      3.3        IMPOSITIONS.  The Mortgagor will pay, or cause to be paid,
when due:

                 3.3.1      All of the following (hereinafter collectively
called the "Impositions"):  all real estate taxes, personal property taxes,
assessments, water and sewer rates and charges, and all other governmental
levies and charges, of every kind and nature whatsoever, general and special,
ordinary and extraordinary, which are assessed, levied, confirmed, imposed or
become a lien upon or against the Property or any portion thereof, and all
taxes, assessments and charges upon the rents, issues, income or profits of the
Property, or which become payable with respect thereto or with respect to the
occupancy, use or possession of the Property, whether such taxes, assessments
or charges are levied directly or indirectly;

                 3.3.2      On the first day of each month after the occurrence

the Mortgagee, for the Impositions (as defined above) and premiums for
insurance required under Section 3.7, below.  Such amount will be held by or on
behalf of the Mortgagee and will be applied to pay such Impositions and
premiums when the same become due.  The Mortgagee will not be required to pay

Mortgagee is not sufficient to pay the Impositions and premiums when due, the





                                      -4-
<PAGE>   123
Mortgagor will, promptly upon request of the Mortgagee, pay to the Mortgagee
any amount necessary to make up such deficiency.

                 3.3.3      If the Mortgagee is not establishing an escrow for

satisfactory to the Mortgagee.  Notwithstanding the provisions of Section
3.3.1, any tax or special assessment which is a lien on the Property may be
paid in installments provided that each installment is paid on or prior to the
date when the same is due without the imposition of any penalty.

      3.4        COMPLIANCE WITH LAWS.  The Mortgagor will promptly comply or
cause compliance with all present and future laws, ordinances, rules,
regulations and other requirements of all governmental authorities having or

or the use or occupancy thereof.

      3.5        CONDITION OF PROPERTY.  The Mortgagor will keep and maintain,
or cause to be kept and maintained, the Property (including all improvements

manner.

      3.6        IMPROVEMENTS.  The Mortgagor will not remove or demolish, or
suffer or permit others to remove or demolish, any improvements installed or
placed on the Property (other than tenant improvements) or, subject to the
provisions of Section 3.5, cause or permit such improvements to be materially
changed or altered without the prior written consent of the Mortgagee, as well
as the Mortgagee's prior written consent to the plans and specifications
relating thereto, and that the Mortgagor will not institute or cause to be
instituted any proceedings that could change the permitted use of the Property
from the use presently zoned.

      3.7        INSURANCE.  The Mortgagor will keep all improvements, if any,
now on, or that hereafter may be put upon, the Property, including fixtures and
all personal property owned by the Mortgagor





                                      -5-
<PAGE>   124
and used in the operation of the Property, insured at all times for the benefit
of the Mortgagee and the Mortgagor, as their respective interests may appear,
against loss or damage by fire, and such other risks of damage, hazards,
casualties and contingencies and in the manner and form and in the amounts as
specified in writing by the Mortgagee from time to time, subject to the
requirements of the Credit Agreement and the following additional terms and
conditions:

                 3.7.1      Such insurance will be issued by a company or
companies and in amounts reasonably acceptable to, and in every respect
satisfactory to, the Mortgagee and will contain a provision requiring that the
coverage evidenced thereby will not be terminated or materially modified
without 30 days' prior written notice to the Mortgagee.  If the Mortgagor fails
to carry any insurance required to be carried by the Mortgagor under the terms
of this Mortgage, the Mortgagee, at its option, may procure and maintain such
insurance and the Mortgagor will promptly reimburse the Mortgagee for any
premiums paid by the Mortgagee for such insurance.  The originals or
appropriate certificates of all policies of insurance required to be carried
under this Mortgage, bearing notations evidencing the payment of premiums or
accompanied by other evidence satisfactory to the Mortgagee of such payment,
will be delivered to the Mortgagee concurrently with the execution and delivery
hereof.  The Mortgagor will deliver to the Mortgagee a new policy (or
certificate, in the case of insurance for which only certificates have been
previously furnished) bearing such notation or accompanied by such other
evidence as replacement for any expiring policy at least 30 days before the
date of such expiration.

                 3.7.2      All policies of insurance required by this Section
3.7 will contain a standard mortgagee clause in favor of the Mortgagee and a
waiver of insurer's right of subrogation against funds paid under the standard
mortgagee endorsement.  In case of a loss payable under such insurance for
damage to or destruction of the Property, the right to adjust all claims under
such insurance policies (jointly with the Mortgagor), and the application of
the proceeds of any such claim, are assigned to the Mortgagee.  The Mortgagor
hereby assigns to the Mortgagee all amounts recoverable under any such policy.
The amount collected by the Mortgagee, at the option of the Mortgagee, may be
used in any one or more of the following ways:  (i) applied to the payment of
any sums then in default under the Indebtedness; (ii) used to fulfill any of
the covenants contained herein which the Mortgagor has failed to fulfill, as
the Mortgagee may determine; (iii) unless





                                      -6-
<PAGE>   125
the insurer denies liability to any insured, used to restore the Property to a
condition satisfactory to the Mortgagee on such terms and conditions as the
Mortgagee may determine; (iv) released to the Mortgagor, provided that if any
sums remain after satisfaction of items (i) or (ii), above, the Mortgagee, at
its election, may apply the same upon the Indebtedness, whether the
Indebtedness is then matured or unmatured.  The Mortgagee is hereby irrevocably
appointed by the Mortgagor as attorney-in-fact of the Mortgagor to assign any
policy in the event of the foreclosure of this Mortgage or other extinguishment
of the Indebtedness, and the Mortgagor will have no right to reimbursement for
premiums unearned at the time of any such assignment.  The rights of the
Mortgagee under this Section 3.7.2 are subject to the rights of the holder of
the mortgage granted to Gem City Savings Association and recorded in Mortgage
Book 457 page 220 of the Greene County, Ohio Recorder's Office, and also to the
rights of the Mortgagor under Section 3.7.3 and 3.7.4 of this Mortgage.

                 3.7.3  If the Property is damaged or destroyed by fire or
other casualty and if no Event of Default has occurred and is continuing, the
Mortgagor, notwithstanding the rights of the Mortgagee under Section 3.7.2
hereof, shall have the right to the proceeds of insurance policies for the
purpose of restoring the property damaged or destroyed to such extent as the
Mortgagor desires for its uses and purposes, in accordance with plans and
specifications approved in writing by the Mortgagee, which approval shall not
be unreasonably withheld, and the Mortgagor and the Mortgagee will apply for
such purpose so much as may be necessary of any proceeds of insurance resulting
from claims for losses under the insurance policies required to be carried by
this Section 3.7.  In such event all insurance proceeds of $50,000 or less for
any one loss shall be paid to the Mortgagor for such purpose.  All such
proceeds in excess of such amount for any one loss shall be paid to and held by
the Mortgagee in a separate interest bearing disbursement account and the
Mortgagee will apply so much as may be necessary of the proceeds to payment of
the costs incurred by the Mortgagee for the restoration of the Property, either
on completion thereof or as the work progresses as directed by the Mortgagor,
subject to the Mortgagee securing such protection against mechanics liens as
the Mortgagee may reasonably require.  If the insurance proceeds will be
insufficient to pay in full the costs of restoration, the Mortgagor will, prior
to the commencement thereof, deposit the deficiency with the Mortgagee in the
separate disbursement account, which deposit shall first be exhausted before
any disbursement of the insurance proceeds.  Any balance of such





                                      -7-
<PAGE>   126
proceeds and any investment income thereon remaining after payment of all costs
of restoration, and all costs reasonably incurred by the Mortgagee in
administering and disbursing the fund, shall be paid to the Mortgagor.

                 3.7.4  Any insurance proceeds applied to the Indebtedness will
be applied first to any payment required to be made by Section 2.5.1(g) of the
Credit Agreement.

      3.8        SALE, TRANSFER OR ENCUMBRANCE.  Except as permitted by the
Credit Agreement, the Mortgagor will not further mortgage, sell or convey,
grant a deed of trust, pledge, grant a security interest in leases, execute a
land contract or installment sales contract, or otherwise dispose of, further
encumber or suffer the encumbrance of, whether by operation of law or
otherwise, any or all of its interest in the Property without the Mortgagee's
prior written consent.

      3.9        MECHANICS LIENS.  The Mortgagor will keep and maintain the
Property free from all liens of persons supplying labor and materials for the
construction, modification, repair or maintenance of any building or
improvements whether on the Property or not.  If any such lien is filed against
the Property, the Mortgagor will discharge the same of record within 30 days
after the lien is filed or, if not filed, within 30 days after the Mortgagor
has notice thereof, provided that, in connection with any such lien or claim
that the Mortgagor may in good faith desire to contest, the Mortgagor may
contest the same by appropriate legal proceedings, diligently prosecuted, upon
the posting of a bond or other security satisfactory to the Mortgagee.

      3.10       EMINENT DOMAIN.  All awards heretofore or hereafter made by
any public or quasi-public authority to the present and any subsequent owner of
the Property by virtue of an exercise of the right of eminent domain by such
authority, including any award for a taking of title, possession or right of
access to a public way, or for any change of grade of streets affecting the
Property, are hereby assigned to the Mortgagee and the Mortgagee, at its
option, is hereby authorized, directed and empowered to collect and receive the
proceeds of any such award from the authorities making the same and to give
proper receipts and acquittances therefor, and, at the Mortgagee's election,
may use such proceeds in any one or more of the following ways:  (a) use the
same or any part thereof to fulfill any of the covenants contained herein as
the Mortgagee may determine, (b) use the same or any part thereof to replace or





                                      -8-
<PAGE>   127
restore the Property to a condition satisfactory to the Mortgagee, (c) apply
the same against the Indebtedness, or (d) release the same to the Mortgagee.
The Mortgagee will have the right to intervene and participate (jointly with
the Mortgagor) in any proceedings for and in connection with any such taking.
Upon the request of the Mortgagee, the Mortgagor will make, execute and deliver
all assignments and other instruments sufficient for the purpose is assigning
all such awards to the Mortgagee free, clear and discharged of all
encumbrances.

      3.11       UNPAID IMPOSITIONS.  In the event that any governmental agency
claims that any tax or other governmental charge or Imposition is due, unpaid
or payable by the Mortgagor or the Mortgagee upon the Indebtedness (other than
income tax, franchise tax or similar tax on the interest or premium receivable
by the Mortgagee thereunder) and including any recording tax, documentary
stamps or other tax or imposition on any of the Indebtedness or this Mortgage,
the Mortgagor forthwith will pay such tax and, within a reasonable time
thereafter, deliver to the Mortgagee satisfactory proof of payment thereof or
if the Mortgagor is contesting the same in good faith, the Mortgagor will
establish with the Mortgagee security in form, substance and amount reasonably
acceptable to the Mortgagee for the payment thereof.

                         ASSIGNMENT OF RENTS AND LEASES

      4.1        ASSIGNMENT.  The Mortgagor hereby transfers and assigns to the
Mortgagee all present and future leases of all or any part of the Property (the
"Leases"), all guarantees of any lessee's performance thereunder, and all
rents, income, revenues and profits arising out of the Property, all as further
security for the payment of the Indebtedness.  The rights assigned hereunder
include but are not limited to all of the Mortgagor's rights (a) to make
material modifications of the Leases; (b) to terminate or to accept the
surrender thereof; (c) to waive or release the lessees from the observance or
performance by the lessees of any material covenant or condition of the leases;
and (d) to give any consent to any assignment of the Leases or any sublease of
any part of the Property.  Any and all Leases will be arms-length agreements
(with persons unrelated to the Mortgagor, the Borrowers or the Guarantors) and
will be at prevailing market rates and terms.

perform all covenants and conditions to be observed or performed by





                                      -11-
<PAGE>   130
the lessor under the Leases and enforce the observance and performance of the
Leases by the lessees.  The Mortgagor will not cancel, surrender, terminate or
materially alter, amend or modify any Leases, release any party liable
thereunder or consent to the assignment of the interests of any lessees without
the prior written consent of the Mortgagee which consent will not be
unreasonably withheld; and the Mortgagee will be deemed to have consented to
any such items if the Mortgagee fails to object thereto within 5 days of
receipt of a written request for the Mortgagee's consent.  The Mortgagor will
not permit the prepayment of any rents under the Leases for more than 30 days
in advance of their due date without the prior written consent of the
Mortgagee.  The form of lease to be used for tenants in the Property will be
submitted to the Mortgagee.

      4.3        INDEMNIFICATION.  The Mortgagee will not be obligated to
perform or discharge any obligation or duty of the Mortgagor under any of the
Leases, and the acceptance of this Assignment does not constitute an assumption
of any such obligation or duty, regardless of whether Mortgagee is collecting
the rent from any such Leases, and Mortgagor specifically acknowledges that
Mortgagee does not have to perform any of Mortgagor's obligations or duties
under the Leases prior to or subsequent to Mortgagee's collection of such
rents.  The Mortgagee will not be deemed to have any responsibility for the
control, care, management or repair of the Property or any responsibility or
liability for any negligence in the management, operation, upkeep, repair or
control of the Property resulting in loss, injury or death to any lessee,
licensee, employee, stranger or other person.  The Mortgagor will indemnify and
hold the Mortgagee harmless against all liabilities, losses and damages that
the Mortgagee may incur under the Leases or under or by reason of this
assignment except for the Mortgagee's wilful negligent acts or liabilities,
losses and damages arising out of the Mortgagee's possession or control of the
Property.

      4.4        RENT.  Provided that no Event of Default (as hereinafter
defined) exists hereunder and Acceleration (as hereinafter defined) has not
occurred, the Mortgagor will have the right to collect all rents under any
Lease (but not more than 30 days in advance of their due date), provided that
upon the occurrence of an Event of Default hereunder and Acceleration
(hereinafter defined), the Mortgagee may take such actions with respect to the
Leases and the rents, issues and profits (including the notification to lessees
to make rent payments directly to the Mortgagee) from the Property, as
permitted by law or in equity, including, but not limited to, the remedies set
forth in Section 6, below.

interest pursuant to the applicable version of the Uniform Commercial Code, and
the Mortgagor hereby grants the Mortgagee a security interest in such items.

      5.2        FILINGS.  The Mortgagor agrees that this instrument, or a
reproduction thereof, may be filed in the real estate records or other
appropriate index, as a financing statement for any of the items specified
above (including fixtures) as part of the Property.  Any reproduction of this
instrument or of any other security agreement or financing statement will be
sufficient as a financing statement.  The Mortgagor agrees to execute and
deliver to the Mortgagee upon request, any financing statements, as well as
extensions, renewals and amendments thereof, and reproductions of this
instrument in such form as the Mortgagee may require to perfect a security
interest with respect to said items.  The Mortgagor will pay all costs of
filing such financing statement and any extensions, renewals, amendments and
releases thereof, and will pay all reasonable costs and expenses of any record
searches for financing statements the Mortgagee may require.

      5.3        BOOKS AND RECORDS.  The Mortgagor will keep its books, records
and documents concerning the Property at the Property or at the address set
forth in Section 7.5, below.  The Mortgagee and its agents may examine and make
extracts and copies from the books, records and documents of the Mortgagor
which relate to the Property.

      5.4        CONTRACTS.  The Mortgagor will observe and perform all
covenants and conditions to be performed by the Mortgagor under any contracts
which are included within the Property, will enforce such contracts, will not
materially modify such contracts, terminate such contracts or release parties
thereto without consent of the Mortgagee and will not assign or encumber its
interest therein.  The assignment and grant of a security interest in the
Property does not constitute an assumption by the Mortgagee of any obligation
or duty thereunder.

      5.5        REMEDIES.  Upon any Event of Default under this instrument and
after Acceleration (hereinafter defined), the





                                      -13-
<PAGE>   132
Mortgagee will have the remedies of a secured party under the Uniform
Commercial Code and, at the Mortgagee's option, may also invoke the remedies
provided in this instrument and/or under applicable law.  In exercising any of
said remedies, the Mortgagee may proceed against the items of real property and
any items of personal property specified above as part of the Property
separately or together and in any order whatsoever, without in any way
affecting the availability of the Mortgagee's remedies under the Uniform
Commercial Code or of the remedies in this instrument.  Taking possession of
any of the Property and the performance of the obligations of the Mortgagor
thereunder will not operate to cure or waive any default or prohibit the taking
of any other action by the Mortgagee under any instrument or at law or in
equity to enforce the payment of the Indebtedness or to realize upon any other
security or guarantee therefor.  The Mortgagee may, so far as the Mortgagor can
give authority therefor, enter upon any premises on which the Property or the
books and records relating to the Property are located and take possession of
and remove the same therefrom.  The Mortgagor waives all claims for damages by
reason of any seizure, repossession, retention or sale of the Property under
the terms hereof.  Any requirement of reasonable notice, if necessary, will be
met if such notice is mailed, postage prepaid, to the address of the Mortgagor
shown in Section 7.5 below at least 10 days before the time of the sale or
other disposition of the Property.  The net proceeds arising from the
disposition of the Property, after deducting the Mortgagee's expenses, will be
applied to the Indebtedness in the order determined by the Mortgagee.  If any
excess remains after the discharge of all of the Indebtedness and the payment
of all such expenses, it will be paid to the Mortgagor.


                                   SECTION 6
                               DEFAULT; REMEDIES

      6.1        EVENTS OF DEFAULT.  The entire Indebtedness will become due,
at the option of the Mortgagee, if any one or more of the Events of Default as
defined in the Credit Agreement occurs and continues beyond any applicable
grace or notice period and if a determination has been made by the Majority
Lenders under Section 7.2 of the Credit Agreement to declare the Obligations to
be due and payable ("Acceleration").  An "Event of Default" under this
Agreement will have the same meaning given such term in the Credit Agreement.





                                      -14-
<PAGE>   133
      6.2        REMEDIES.  Upon maturity of any of the Indebtedness or at any
time after an Event of Default and Acceleration (except as provided
hereinbelow), the Mortgagee will have all rights and remedies provided at law
or in equity or under this Mortgage, including the right to accelerate the
maturity of the Indebtedness and the right to foreclose the lien of this
Mortgage.  Notwithstanding anything to the contrary contained in this Section
6.2, the rights and remedies granted to the Mortgagee subsequent to an Event of
Default, which rights and remedies are specified in Section 3.3.2 hereof, do
not require an Acceleration before the Mortgagee may exercise any of such
rights or remedies.

      6.3        WAIVERS.  The failure of the Mortgagee to exercise either or
both of its options to accelerate the maturity of the indebtedness secured
hereby and to foreclose the lien hereof following any Event of Default, or to
exercise any other option granted to the Mortgagee of partial payments of such
indebtedness, will neither constitute a waiver of any such default or of the
Mortgagee's options hereunder nor establish, extend or affect any grace period
for payments due under the Note, but such options will remain continuously in
force.  Acceleration of maturity, once claimed hereunder by the Mortgagee, may,
at the Mortgagee's option, be rescinded by written acknowledgment to that
effect by the Mortgagee and will not affect the Mortgagee's right to accelerate
maturity upon or after any future default.

      6.4        EXPENSES.  In any proceeding to foreclose the lien of this
Mortgage or enforce any other remedy of the Mortgagee under the Indebtedness,
this Mortgage or any other document securing the Indebtedness, or in any other
proceeding whatsoever in connection with any of the Property in which the
Mortgagee is named as a party, there will be allowed and included, as
additional indebtedness in the judgment or decree resulting therefrom, all
expenses paid or incurred in connection with such proceeding by or on behalf of
the Mortgagee constituting attorneys' fees, appraisers' fees, outlays for
documentary and expert evidence, stenographers' charges, publication costs,
survey costs, and costs (which may be estimated as to items to be expended
after entry of such judgment or decree) of procuring all abstracts of title,
title searches and examinations, title insurance policies, Torrens certificates
and any similar data and assurances with respect to title to the Property as
the Mortgagee may deem reasonably necessary either to prosecute or defend in
such proceeding or to evidence to bidders at any sale pursuant to such decree
the true condition of the title to or value of the premises or the Property.





                                      -15-
<PAGE>   134
All expenses of the foregoing nature, and such expenses as may be incurred in
the protection of any of the Property and the maintenance of the lien of this
Mortgage thereon, including, without limitation, the fees of any attorney
employed by the Mortgagee in any litigation affecting the Note, this Mortgage
or any of the Property, or in preparation for the commencement or defense of
any proceeding or threatened suit or proceeding in connection therewith, will
be immediately due and payable by the Mortgagor with interest thereon at the
Default Rate as defined in the Credit Agreement, but not higher than the
highest rate permitted by law.

      6.5        PROCEEDS.  The proceeds of any foreclosure sale of the
Property, or any part thereof, will be distributed and applied in the following
order of priority:  (a) on account of all costs and expenses incident to the
foreclosure proceedings, including all such items as are mentioned in Section
6.4 hereof; (b) all other items that, under the terms of this Mortgage,
constitute secured indebtedness additional to that evidenced by the
Indebtedness, with interest thereon at the Default Rate as defined in the
Credit Agreement; (c) all principal and interest remaining unpaid under the
Indebtedness, in the order of priority specified by the Mortgagee in its sole
discretion; and (d) the balance to the Mortgagor or its successors or assigns,
as its interests may appear.

      6.6        ADDITIONAL REMEDIES.  If an Event of Default occurs and is
continuing and after Acceleration, the Mortgagee, at its option, in addition to
the other remedies provided herein or in law or equity, may proceed to enter
upon, take possession of, and manage and operate the Property and may proceed
to perform any or all obligations of the Mortgagor under the Leases, and
exercise the rights of the Mortgagor contained therein as fully as the
Mortgagor itself could, without regard to the adequacy of security for the
indebtedness hereby secured and with or without bringing any legal action or
causing any receiver to be appointed by any court; may let or re-let the
Property or any part thereof and enforce, modify, cancel or accept the
surrender of any of the Leases; may bring or defend any suits in connection
with the possession of the Property or any part thereof, in the name of either
the Mortgagor or the Mortgagee; may make such repairs as the Mortgagee may deem
appropriate; may pay out of rents, income or profits any liens, taxes,
assessments, insurance premiums, utility charges or costs of keeping the
Property in good condition and repair; may in the name of either the Mortgagor
or the Mortgagee sue for or otherwise





                                      -16-
<PAGE>   135
collect and receive all rents, issues and profits, including those past due and
unpaid; and may do all other things the Mortgagee may deem necessary or proper
to protect its security.  Entry upon and taking possession of the Property and
the collection of the rents and the application thereof will not operate to
cure or waive any default under any instrument given by the Mortgagor to the
Mortgagee or prohibit the taking of any other action by the Mortgagee under any
such other instrument, or at law or in equity to enforce the payment of the
indebtedness secured hereby or to realize on any other security or guarantee.

      6.7        RECEIVER.  Upon or at any time after the occurrence of an
Event of Default hereunder and Acceleration, the Mortgagee may request the
appointment of a receiver of the Property.  Such appointment may be made either
before or after any foreclosure action or sale, without notice and without
regard to the solvency or insolvency, at the time of application for such
receiver, of the person or persons, if any, liable for the payment of the
indebtedness secured hereby without regard to the value of the Property at such
time and whether or not the same is then occupied as a homestead and without
bond being required of the applicant.  Such receiver will have the power to
take possession, control and care of the Property and to collect all rents,
issues, deposits and profits thereof.

      6.8        RIGHTS OF MORTGAGEE.  If the Mortgagor fails to pay any
Impositions or to make any other payment required to be paid by the Mortgagor
under this Mortgage at the time and in the manner provided in this Mortgage, or
if an Event of Default occurs under this Mortgage, then without limiting the
generality of any other provision of this Mortgage and without waiving or
releasing the Mortgagor from any of its obligations hereunder, the Mortgagee
will have the right, but will be under no obligation, to pay any Impositions or
other payment, or any sums due under this Mortgage, and may perform any other
act or take such action as may be appropriate to cause such other term,
covenant, condition or obligation to be promptly performed or observed on
behalf of the Mortgagor, provided that, unless in the Mortgagee's judgment the
sending of a l0-day notice will impair the security of the lien of the
Mortgage, the Mortgagee will give the Mortgagor 10 days' prior written notice
prior to making any such payment.  In any such event, the Mortgagee and any
person designated by the Mortgagee will have, and is hereby granted, the right
to enter upon the Property at any time and from time to time for the purpose of
performing any such act or taking any such action, and all monies





                                      -17-
<PAGE>   136
expended by the Mortgagee in connection with making such payment or performing
such act (including, but not limited to, legal expenses and disbursements),
together with interest thereon at the Default Rate specified in the Credit
Agreement, but not higher than the highest rate permitted by law, from the date
of each such expenditure, will be paid by the Mortgagor to the Mortgagee
forthwith upon demand by the Mortgagee and will be secured by this Mortgage.


                                   SECTION 7
                                 MISCELLANEOUS

      7.1        RIGHTS CUMULATIVE.  The rights of the Mortgagee arising under
the provisions and covenants contained in this Mortgage and the Indebtedness
and other documents securing the Indebtedness or any part thereof will be
separate, distinct and cumulative and none of them will be exclusive of the
others.  No act of the Mortgagee will be construed as an election to proceed
under any one provision herein or in such other documents to the exclusion of
any other provision, anything herein or otherwise to the contrary
notwithstanding.

      7.2        WAIVERS.  A waiver in one or more instances of any of the
terms, covenants, conditions or provisions hereof, or of the Note or any
documents securing the Indebtedness or any part thereof, will apply to the
particular instance or instances and at the particular time or times only, and
no such waiver will be deemed a continuing waiver, but all of the terms,
covenants, conditions and other provisions of this Mortgage and of such other
documents will survive and continue to remain in full force and effect.  No
waiver will be asserted against the Mortgagee unless in writing signed by the
Mortgagee.

      7.3        TITLE.  The titles to the Sections hereof are for reference
only and do not limit in any way the content thereof.

      7.4        AMENDMENTS.  No change, amendment, modification, cancellation
or discharge hereof, or any part hereof, will be valid unless in writing and
signed by the parties hereto or their respective successors and assigns.

      7.5        NOTICES.  All notices, demands and requests given or required
hereunder to be given by either party hereto to the other party will be in
writing and will be deemed to have been properly given if sent by certified
mail, postage prepaid, return receipt requested, addressed as follows:

time designate by written notice.

            7.6       CONSTRUCTION.  Any words herein which are used in one
gender will be read and construed to mean or include the other gender wherever
they would so apply.  Any words herein which are used in the singular will be
read and construed to mean and to include the plural wherever they would so
apply, and vice versa.
            7.7       WAIVERS BY MORTGAGOR.  The Mortgagor hereby expressly
waives, to the extent permitted by law, the equity of redemption, any statutory
right of redemption, dower and homestead and all other rights and exemptions of
every kind in and to the Property.

            7.8       INTEREST.  If from any circumstances whatsoever the
fulfillment of any provision of this instrument involves transcending the limit
of validity prescribed by any applicable usury statute or any other applicable
law (it being the intention of the Mortgagor and the Mortgagee that the laws of
the Commonwealth of Pennsylvania will govern) with regard to obligations of
like character and amount, then the obligation to be fulfilled will be reduced
to the limit of such validity as provided in such statute or law, so that in no
event will any exaction of interest be possible under this instrument in excess
of the limit of such validity.  In no event will the Mortgagor be bound to pay
interest of more than the legal limit for the use, forbearance or detention of
money and the right to demand any such excess is hereby expressly waived by the
Mortgagee.

            7.9       RELEASES.  The Mortgagor agrees that the Mortgagee,
without notice to or further consent of the Mortgagor, may release





                                      -19-
<PAGE>   138
or discharge any persons who are or may become liable for the payment of the
Indebtedness or release or discharge any other collateral for the payment of
the Indebtedness and any such release or discharge will not alter, modify,
release or limit the validity and enforceability of this Mortgage or the
liability of the Mortgagor under the Indebtedness or this Mortgage.


                                   SECTION 8
                                FUTURE ADVANCES

            8.1       FUTURE ADVANCES BY MORTGAGEE.  This Mortgage will secure
unpaid balances of any loan advances made by the Mortgagee after this Mortgage
is delivered for record to the extent that the total unpaid loan indebtedness,
exclusive of interest thereon, does not exceed the maximum amount of unpaid
loan indebtedness which may be outstanding at any time, which is Twenty-Five
Million Dollars ($25,000,000), provided that this Mortgage will also secure
unpaid balances of advances made for the payment of taxes, assessments,
insurance or costs incurred for the protection of the Property.  The Mortgagor
further covenants and agrees to repay all such loan advances with interest,
such loan advances to be evidenced by an additional note or notes to be given
to the Mortgagee at the time of such advances, and that the covenants contained
in this Mortgage will apply to such loan advances as well.  This Mortgage is
given to secure repayments of advances made pursuant to the Credit Agreement
which advances are obligatory pursuant to the terms and conditions of the
Credit Agreement.

            8.2       OTHER LIENS.  It is agreed that the lien hereby created
will take precedence over and be a prior lien to any other lien of any
character whether vendor's, materialmen's or mechanic's lien hereafter created
on the Property, and in the event the proceeds of the Indebtedness secured
hereby as set forth herein are used to pay off and satisfy any liens heretofore
existing on the Property, then the Mortgagee is, and will be, subrogated to all
of the rights, liens and remedies of the holders of the indebtedness so paid.


                                   SECTION 9
                                   DEFEASANCE

            Provided, nevertheless, that if the Mortgagor keeps, observes and
performs all of the covenants and conditions of this Mortgage on its part to be
kept and performed and pays, or causes to be





                                      -20-
<PAGE>   139
paid, to the Mortgagee the Indebtedness as to both principal and interest, and
all amendments, extensions and renewals thereof, and all of the other
Indebtedness, and repays any loans and advances hereafter made by the Mortgagee
under the terms hereof, and the Mortgagee cancels this Mortgage in writing,
then this Mortgage will be void, otherwise it will remain in effect.

                                   ARTICLE I

                                   BACKGROUND

         The Mortgagor and the Mortgagee acknowledge that:

         1.      In accordance with the terms of a Credit Agreement and other
Loan Documents (as defined in the Credit Agreement) dated as of November 14,
1991, the Mortgagor executed and delivered an Open-End Mortgage, Assignment of
Rents and Leases and Security Agreement, dated as of November 14, 1991, to the
Administrative Agent.

         2.      Certain modifications were made to the Credit Agreement
shortly before its execution and the Open-End Mortgage, Assignment of Rents and
Leases and Security Agreement should be amended to address those modifications.

         3.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement was recorded in book number ____, page number ____ and
covers property described in Exhibit A attached hereto.

         4.      The Mortgagor and Mortgagee now wish to amend and supplement
the Open-End Mortgage, Assignment of Rents and Leases and Security Agreement it
issued on November 14, 1991 in order to address the above-referenced
modifications made to the Credit Agreement.

                                   ARTICLE II

                                   AMENDMENTS

         1.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement is amended, effective as of November 22, 1991, to delete
Section 4.4 appearing therein in its entirety and inserting, in its place, the
following:

                 "4.4      RENT.  Provided that no Acceleration, Termination or
Maturity (each as hereinafter defined) has occurred, the Mortgagor will have
the right to collect all rents under any Lease (but not more than 30 days in
advance of their due date), provided that upon the occurrence of an
Acceleration, a Termination or a Maturity (each as hereinafter defined), the
Mortgagee may take such
<PAGE>   143
actions with respect to the Leases and the rents, issues and profits (including
the notification to lessees to make rent payments directly to the Mortgagee)
from the Property, as permitted by law or in equity, including, but not limited
to, the remedies set forth in Section 6, below."

         2.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement is amended, effective as of November 20, 1991, to delete
Section 5.5 appearing therein in its entirety and inserting, in its place, the
following:

                 "5.5  REMEDIES.  Upon any Acceleration, Termination or
Maturity (each as hereinafter defined), the Mortgagee will have the remedies of
a secured party under the Uniform Commercial Code and, at the Mortgagee's
option, may also invoke the remedies provided in this instrument and/or under
applicable law.  In exercising any of said remedies, the Mortgagee may proceed
against the items of real property and any items of personal property specified
above as part of the Property separately or together and in any order
whatsoever, without in any way affecting the availability of the Mortgagee's
remedies under the Uniform Commercial Code or of the remedies in this
instrument.  Taking possession of any of the Property and the performance of
the obligations of the Mortgagor thereunder will not operate to cure or waive
any default or prohibit the taking of any other action by the Mortgagee under
any instrument or at law or in equity to enforce the payment of the
Indebtedness or to realize upon any other security or guarantee therefor.  The
Mortgagee may, so far as the Mortgagor can give authority therefor, enter upon
any premises on which the Property or the books and records relating to the
Property are located and take possession of and remove the same therefrom.  The
Mortgagor waives all claims for damages by reason of any seizure, repossession,
retention or sale of the Property under the terms hereof.  Any requirement of
reasonable notice, if necessary, will be met if such notice is mailed, postage
prepaid, to the address of the Mortgagor shown in Section 7.5 below at least 10
days before the time of the sale or other disposition of the Property.  The net
proceeds arising from the disposition of the Property, after deducting the
Mortgagee's expenses, will be applied to the Indebtedness in the order
determined by the Mortgagee.  If any excess remains after the discharge of all
of the Indebtedness and the payment of all such expenses, it will be paid to
the Mortgagor."

         3.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement is amended, effective as of November 20, 1991, to delete
Section 6.1 appearing therein in its entirety and inserting, in its place, the
following:

                 "6.1  EVENTS OF DEFAULT; ACCELERATION; TERMINATION; MATURITY.
The entire Indebtedness will become due for the





                                      -2-
<PAGE>   144
purposes of this Agreement if (i) any of the Notes or Obligations are not paid
at the Termination Date (as defined in the Credit Agreement) (a "Maturity"), or
(ii) the entire Indebtedness becomes due as provided in either Section 7.2(a)
or Section 7.2(c) of the Credit Agreement (an "Acceleration").  An Event of
Default under this Agreement will have the same meaning given such term in the
Credit Agreement.  A "Termination" under this Agreement will occur if the
Administrative Agent declares the Revolving Commitment to be terminated in
accordance with either Section 7.2(a) or Section 7.2(c) of the Credit
Agreement."

         4.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement is amended, effective as of November 20, 1991, to delete
Section 6.2 appearing therein in its entirety and inserting, in its place, the
following:

                 "6.2  REMEDIES.  Upon an Acceleration, a Termination or a
Maturity, the Mortgagee will have all rights and remedies provided at law or in
equity or under this Mortgage, including the right to accelerate the maturity
of the Indebtedness and the right to foreclose the lien of this Mortgage.
Notwithstanding anything to the contrary contained in this Section 6.2, the
rights and remedies granted to the Mortgagee subsequent to an Event of Default,
which rights and remedies are specified in Section 3.3.2 hereof, do not require
an Acceleration, a Termination or a Maturity before the Mortgagee may exercise
any of such rights or remedies."

         5.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement is amended, effective as of November 20, 1991, to delete
Section 6.3 appearing therein in its entirety and inserting, in its place, the
following:

                 "6.3      WAIVERS.  The failure of the Mortgagee to exercise
either or both of its options to accelerate the maturity of the indebtedness
secured hereby and to foreclose the lien hereof following an Acceleration or a
Termination, or to exercise any other option granted to the Mortgagee of
partial payments of such indebtedness, will neither constitute a waiver of any
event of default or of the Mortgagee's options hereunder nor establish, extend
or affect any grace period for payments due under the Note, but such options
will remain continuously in force.  Once the Mortgagee has accelerated the
maturity of the Indebtedness secured hereby, the Mortgagee, at its option, may,
by written notice, rescind, such acceleration and such rescission will not
affect the Mortgagee's right to accelerate maturity upon or after any future
default."

         6.      The Open-End Mortgage, Assignment of Rents and Leases and
Security Agreement is amended, effective as of November 20, 1991,





                                      -3-
<PAGE>   145
to delete Section 6.6 appearing therein in its entirety and inserting, in its
place, the following:

                 "6.6      ADDITIONAL REMEDIES.  After an Acceleration, a
Termination or a Maturity, the Mortgagee, at its option, in addition to the
other remedies provided herein or in law or equity, may proceed to enter upon,
take possession of, and manage and operate the Property and may proceed to
perform any or all obligations of the Mortgagor under the Leases, and exercise
the rights of the Mortgagor contained therein as fully as the Mortgagor itself
could, without regard to the adequacy of security for the indebtedness hereby
secured and with or without bringing any legal action or causing any receiver
to be appointed by any court; may let or re-let the Property or any part
thereof and enforce, modify, cancel or accept the surrender of any of the
Leases; may bring or defend any suits in connection with the possession of the
Property or any part thereof, in the name of either the Mortgagor or the
Mortgagee; may make such repairs as the Mortgagee may deem appropriate; may pay
out of rents, income or profits any liens, taxes, assessments, insurance
premiums, utility charges or costs of keeping the Property in good condition
and repair; may in the name of either the Mortgagor or the Mortgagee sue for or
otherwise collect and receive all rents, issues and profits, including those
past due and unpaid; and may do all other things the Mortgagee may deem
necessary or proper to protect its security.  Entry upon and taking possession
of the Property and the collection of the rents and the application thereof
will not operate to cure or waive any default under any instrument given by the
Mortgagor to the Mortgagee or prohibit the taking of any other action by the
Mortgagee under any such other instrument, or at law or in equity to enforce
the payment of the indebtedness secured hereby or to realize on any other
security or guarantee."

Corporation until December 31, 1997.

<PAGE>   2
5.  Maximum Number of Shares Subject to Option.

    Each eligible employee shall be entitled to place under option any number
of whole Shares up to a maximum of 200 Shares.

6.  Employee's Election to Participate.

    (a)  Within 30 days following the date of notice of the granting of the
option, each eligible employee who elects to place Shares under option shall so
indicate by properly completing and signing the form which shall accompany such
notice and mailing or delivering such form to James W. Hoose, Sr., Human
Resources Director for KLSI.

    (b)  An election to place Shares under option will not constitute an
obligation to purchase any of the Shares placed under option. Such an election
will merely notify the Corporation of the number of Shares to be held under
option for the employee.

    (c)  An employee who fails to elect participation in the Plan in the manner
and within the time provided or to authorize and maintain the payroll
deductions hereinafter provided shall have no further rights under the Plan.

    (d)  An employee electing to participate may do so with respect to all or
any portion of the Shares which he is entitled to place under option.

7.  Payroll Deductions.

    (a)  Concurrently with election to participate in the Plan the employee
must authorize a payroll deduction of an amount sufficient to pay for all of
the Shares the employee holds under option by the Plan Termination Date,
subject to adjustment as necessary from time to time.

    (b)  Payroll deductions shall commence as of the first payroll following
election to participate in the Plan and shall continue until the employee has
paid in full for the number of Shares he elects to hold under option or until
the employee elects to abandon this option, whichever event shall first occur.
The employee may make cash payments for the Shares at any time.

    (c)  The application by the employee to participate in the Plan will
contain the following signed statement by the Company; "This counterpart in the
hands of the employee whose signature is affixed above will constitute a
nonassignable certificate of indebtedness subject to all the terms and
provisions of the Plan."

8.  Issuance and Delivery of Stock Certificates.

    Certificates for shares will be issued and delivered to the employee for
the number of shares paid for as soon as practicable after the Plan Termination
Date. No fractional Shares will be issued.

9.  Employee's Right to Abandon Option.

    At any time during the term of the Plan an employee may elect to abandon
his option with respect to all or any number of the Shares then under option.
As to any Shares so abandoned, the employee shall have no further option or
right of any nature at any subsequent time. Upon such abandonment, the
Corporation will pay to the employee with interest as hereafter provided the
amount of his payroll deduction or cash payments applicable to the abandoned
shares.

10. Interest on Payroll Deductions or Cash Payments.

    Whether or not an employee applies his accumulated payroll deductions or
cash payments to the purchase of the Shares or elects to withdraw from the Plan
and receive payment of the amount of his accumulated payroll deductions or cash
payments, the amount of each employee's payroll deductions or cash payments
shall constitute indebtedness of the Corporation to him until applied to the
purchase of Shares or until payment to him and such indebtedness shall bear
interest at the rate of 7 percent per annum.

11. Term of the Plan.

    The term of the Plan shall commence on the Plan Entry Date and end on the
Plan Termination Date. In the event of a change of control of the Corporation
or any participating subsidiary of the Corporation as determined by the Board,
the Plan shall end and the Corporation shall either (I) pay each affected
participating employee the amount of his accumulated payroll deduction or cash
payments, with interest as provided herein, or (ii) have issued to such
employee the number of whole Shares fully paid for by such employee to such
date and any excess in cash.

12. Termination of Employment.

    If a participating employee ceases to be employed for any reason prior to
December 31, 1997, the Corporation shall pay to him his accumulated payroll
deductions or cash payments with interest as provided above to the date of
termination.

13. Options Not Transferable.

    Options under this Plan shall not be transferable by any employee nor be
exercisable by any person other than the employee.

14. Share Dividend or Recapitalization.

    If any share dividend is declared upon the Shares, or if there is any
recapitalization of the Corporation with respect to its Shares resulting in a
split-up or combination or exchange of Shares the number and kind of shares
then subject to options granted to eligible employees under the Plan shall be
proportionately and appropriately adjusted by the Board without any change in
the aggregate purchase prices to be paid therefor.

15. Administration.

    The Plan will be administered by an Employee Stock Purchase Plan Committee
composed of three members to be selected from time to time by the Board. The
Committee may prescribe rules and regulations from time to time for the
administration of the Plan and may decide questions which may arise with
respect to its interpretation or application.  The Committee shall interpret
and apply the Plan so that it qualifies as an employee stock purchase plan
within the meaning of Section 423 of the Internal Revenue Code of 1986.

16. Share Ownership.

    Notwithstanding anything herein to the contrary, no employee shall be
entitled to place any Shares under option under the Plan if such employee,
immediately after the placing of such Shares under option, owns Shares
(including all shares which may be purchased under





                                       3
<PAGE>   4
outstanding options) possessing 5 percent or more of the total combined voting
power or value of all classes of shares of the Corporation or of its parent or
subsidiary corporation. For the foregoing purposes the rules of section 424(d)
of the Internal Revenue Code of 1986 shall apply in determining share
ownership. Also, no employee shall be granted an option under the Plan which
permits his rights to purchase Shares under all Share purchase plans of the
Corporation and its parent and subsidiary corporations to accrue at a rate
which exceeds $25,000 of fair market value of such shares (determined at the
time such option is granted) for each calendar year in which such option is
outstanding at any time.

17. Renewal of the Plan by the Board.

    The Board may, in its discretion, renew the Plan for four one year periods
with such changes therein as it deems appropriate provided that the Plan, as
amended, continues to qualify as an employee stock purchase plan within the
meaning of Section 423 of the Internal Revenue Code of 1986.

18. Shareholder Approval.

    The Plan is subject to approval by the holders of a majority of the Shares
constituting a quorum and present, in person or by proxy, at a meeting of the
Shareholders of the Corporation held on or before November 7, 1997.
