OVERVIEW

     The Company is an independent contract manufacturer of electronic
components, printed circuit board assemblies and completely assembled
(box-build) electronic products.  Included among the wide range of services the
Company offers its customers are (1) manual and automatic assembly and testing
of products, (2) material sourcing, procurement, (3) design, manufacturing and
test engineering support, (4) warehousing and shipment services, and (5)
assistance in obtaining product approvals from governmental and other
regulatory bodies.  The Company provides these services through facilities
located in North America and the Far East.

     The Company provides manufacturing and assembly services ranging from the
assembly of individual components to the assembly and testing of box-build
electronic products.  The Company has the ability to produce assemblies
requiring mechanical as well as electronic capabilities.  The products
assembled by the Company are then incorporated into finished products sold in
various marketplaces, including automotive, fitness, consumer electronics,
telecommunications, gaming, home appliances and industrial electronics.
                                      
                                      3


<PAGE>   4

     The Company operates manufacturing facilities in Elk Grove Village,
Illinois; Las Vegas, Nevada; and Acuna, Mexico.  The Company maintains
materials sourcing offices in Elk Grove Village, Illinois and Taipei, Taiwan.
The Company provides warehousing services in Del Rio, Texas and Huntsville,
Alabama.  In addition, the Company's 42.5% affiliate, SMT Unlimited L.P.
(SMTU), provides contract manufacturing services in Fremont, California.

     The Company is a Delaware corporation which was organized on November 16,
1993 and commenced business when it became the successor to all of the assets
and liabilities of SigmaTron L.P., an Illinois limited partnership, through a
reorganization on February 8, 1994.  On February 9, 1994, the Company and
certain stockholders commenced an initial public offering for the sale of
1,265,000 shares of common stock.

PRODUCTS AND SERVICES

     The Company provides a broad range of manufacturing-related outsourcing
solutions for its customers on both a turnkey (material purchased by the
Company) and consignment basis (material provided by the customer).  These
solutions incorporate the Company's knowledge and expertise in the electronic
manufacturing services industry to provide its customers with advanced
manufacturing technologies and high quality, responsive and flexible
manufacturing services.  SigmaTron's outsourcing solutions provide services
from product inception through the ultimate delivery of a finished good.  Such
technologies and services include the following:

     Manufacturing and Related Services.  As its customers experience greater
competition and shorter product life cycles in their respective industries, the
Company has responded by expanding its prototype services.  The Company also
provides quick-turnaround, turnkey prototype services from dedicated resources
located within the Company's Elk Grove Village facility and through SMTU, its
affiliate, which it makes available to customers which it believes will lead to
significant orders.

     Materials Procurement.  Since the Company is primarily a turnkey
manufacturer it directly sources all, or a substantial portion, of the
components necessary for its product assemblies, rather than receiving the raw
materials from its customers on consignment.  Material procurement includes the
purchasing, management, storage and delivery of raw components required for the
manufacture or assembly of a customer's product based upon the customer's
orders.  The Company procures components from a select group of vendors which
meet its standards for timely delivery, high quality and cost effectiveness, or
as directed by its customers.  Raw material used in the assembly and
manufacture of printed circuit boards and electronic assemblies are generally
available from several suppliers, unless restricted by the customer.

     The Company believes that its ability to source and procure
competitively priced, quality components is critical to its ability to
effectively compete. In addition to obtaining materials in North America, the
Company utilizes its Taiwanese procurement 

                                      4
                                      

<PAGE>   5

office and agents to source materials from the Far East.  SigmaTron
believes this office allows the Company to more effectively manage its
relationships with key suppliers in the Far East by allowing the Company to
respond more quickly to changes in market dynamics, including fluctuations in
price, availability and quality.

     Assembly and Manufacturing.  The Company's core business is the assembly
of printed circuit boards through the automated and manual insertion of
components onto raw printed circuit boards.  The Company offers its assembly
services using both pin-through-hole ("PTH") and surface mount ("SMT")
interconnect technologies.  SMT is an assembly process which allows the
placement of a higher density of components directly on both sides of a printed
circuit board.  The SMT process is a more recent advancement over the mature
PTH technology, which normally permits electronic components to be attached to
only one side of a printed circuit board by inserting the component into holes
drilled through the board.  The SMT process allows original equipment
manufacturers ("OEMs") to use advanced circuitry, while at the same time
permitting the placement of a greater number of components on a printed circuit
board without having to increase the size of the board.  By allowing
increasingly complex circuits to be packaged with the components in closer
proximity to each other, SMT greatly enhances circuit processing speed, and
thus, board and system performance.

     The Company performs PTH assembly both manually and with automated
component insertion and soldering equipment.  Although SMT is a newer and more
sophisticated interconnect technology, the Company intends to continue
providing PTH assembly services for its customers because it believes that SMT
will not entirely eliminate the need for PTH technology.  SigmaTron also
possesses BGA technology, which is used for more complex circuit boards
required to perform at higher speeds.  The Company believes that OEMs with
products not limited by internal space constraints will continue to favor PTH
over SMT.  Together with PTH and SMT, the Company and its affiliate SMTU also
provide more advanced interconnect technologies, such as BGA and fine pitch
SMT.

     In addition to printed circuit board assemblies, the Company also
manufactures DC-to-AC inverters, coils, transformers and cable and harness
assemblies.  These products are manufactured using both automated and
semi-automated preparation and insertion equipment and manual assembly
techniques.

     In response to the needs of its OEM customers, the Company also offers
"box-build" services which integrate its printed circuit board and other
manufacturing and assembly technologies into higher level sub-assemblies and
end products.

     Product Testing.  The Company has the ability to perform both
in-circuit and functional testing of its assemblies and finished products. 
In-circuit testing verifies that the correct components have been properly
inserted and that the electrical circuits are complete.  Functional testing
determines if a board or system assembly is performing to customer
specifications.   The Company provides X-ray laminography services through 


                                      5
                                      
<PAGE>   6

its affiliate SMTU.  Usually, the Company either designs or procures
test fixtures.  The Company seeks to provide customers with highly
sophisticated testing services that are at the forefront of current test
technology.

     Warehousing and Distribution.  In response to the needs of select
customers, the Company has the ability to provide in-house warehousing,
shipping and receiving and customer brokerage services for goods manufactured
or assembled in Mexico and for goods manufactured for a customer in Huntsville,
Alabama.  The Company also has the ability to provide custom-tailored delivery
schedules to fulfill the just-in-time inventory needs of its customers.

MARKETS AND CUSTOMERS

     SigmaTron's customers are in the consumer electronics, gaming, industrial
electronics, fitness, telecommunications, automotive and home appliance
industries.  As of April 30, 1997, the Company had approximately 115 active
customers ranging from Fortune 500 companies to small, privately held
enterprises.

     The following table shows, for the periods indicated, the percentage of
net sales to the principal end-user markets it serves.

     For the fiscal year ended April 30, 1997, Nighthawk, Bally Gaming, and
Life Fitness accounted for 29.8%, 13.5% and 10.8%, respectively, of the
Company's net sales as compared to 28.2%, 15.0% and 10.4%, respectively, of the
Company's net sales for the fiscal year ended April 30, 1996.  In addition,
Bally Gaming, Life Fitness and Four Star Tool accounted for 33.7%, 16.4% and
12.5%, respectively, of the Company's net sales for the fiscal year ended April
30, 1995.  The Company expects that these customers as a group will continue to
account for a significant percentage of the Company's net sales, although the
individual percentages may vary from period to period.

     NSI is a leading U.S. manufacturer of residential carbon monoxide
detection systems.  The Company's current agreement with NSI calls for the
Company to function as the exclusive contract manufacturer for all models of
NSI's proprietary carbon monoxide detectors on a turnkey basis through June
1998.  The Company has agreed that during the term of the agreement and for
three months thereafter it will not produce carbon monoxide detectors for any
other customer.  The Company expects that sales to NSI will continue to account
for a significant percentage of the Company's net sales.  Sales to NSI are
seasonal due to the nature of the product and the Company experiences stronger
sales to NSI in the fall and winter months.  The NSI market is an emerging
market which could lead to volatility in its forecast.  The volatility of NSI
orders may cause the Company's revenues to fluctuate significantly on a
seasonal basis.

SALES AND MARKETING

     The Company markets its services through seven independent
manufacturers' representative organizations, that currently employ
approximately thirty-five sales personnel in the United States and Canada. 
Independent manufacturers' representative organizations receive variable
commissions based on orders received by the Company.  The members of the
Company's senior management are actively involved in sales and marketing
efforts.  The Company has a media program in place.  In addition, the Company
attends trade shows related to its industry and its major customer industries.

                                      
                                      7

<PAGE>   8

     Sales volume and gross profit margins can vary considerably among
customers and products depending on the type of services rendered by the
Company.  Specifically, variations in orders for turnkey services versus
consignment services and variations in the number of orders for products with
high raw material costs can lead to significant fluctuations in the Company's
operating results.  Further, customers' orders can be delayed, rescheduled or
canceled at any time, which can significantly impact the operating results of
the Company.  The ability to replace such delayed or lost sales in a short
period of time is not assured.

MEXICAN OPERATIONS

     The Company's wholly-owned subsidiary, Standard Components de Mexico, S.A.
("Standard Components"), a Mexican corporation, is located in Acuna, Mexico, a
border town along the Rio Grande River next to Del Rio, Texas, which is 155
miles west of San Antonio.  Standard Components was incorporated and commenced
operation in 1969.

     Standard Components is a maquiladora, which is the status afforded a
corporation under a trade agreement between the United States of America and
Mexico.  Standard Components' operations have resulted in an immaterial profit
each year, since the Company acquired it in 1994.

     In 1995 the Mexican Ministry of Finance and Public Credit (Hacienda)
adopted rules which would require arms length pricing for transactions between
maquiladoras and their U.S. affiliated companies.  The Company is currently
assessing the impact of these rules on its operations and would expect to
report additional profit in Mexico in the future.

     The Company believes that one of the key benefits to having operations in
Mexico is its access to cost effective labor resources.

     The Company believes economic events effecting the Mexican economy and the
implementation of NAFTA have not had a material effect on the Company or its
financial position.

     The Company provides the funds necessary to operate Standard Components.
Since the Company provides funding to Standard Components in U.S. dollars,
which are exchanged for pesos as needed, the devaluation of the peso, without
an equal or greater increase in Mexican inflation, has not had a material
impact on the financial results of the Company.  In fiscal 1997 the Company
funded approximately $5,970,000.

COMPETITION

     The electronic manufacturing services industry is highly competitive and
subject to rapid change.  Furthermore, both large and small companies compete
in the industry, and many may have significantly greater financial resources,
more extensive business 


                                      8
                                      
<PAGE>   9


experience and greater marketing and production capabilities than the
Company.  Also, foreign companies, especially companies with production
operations in the Far East, may have substantially lower costs and thus may be
able to offer their services at lower prices.  The significant competitive
factors in this industry include price, quality, service, timeliness,
reliability, the ability to source raw components, and manufacturing and
technological capabilities.  The Company believes it can competitively provide
all of these services.

     In addition, the Company may be operating at a cost disadvantage compared
to manufacturers who have greater direct buying power with component suppliers
or who have lower cost structures.  Current and prospective customers
continually evaluate the merits of manufacturing products internally and will
from time to time offer manufacturing services to third parties in order to
utilize excess capacity.  During downturns in the electronics industry, OEMs
may become more price sensitive.

     There can be no assurance that competition from existing or potential
competitors will not have a material adverse effect on the Company's business,
financial condition, or results of operations.  The introduction of lower
priced competitive products or significant price reductions by the Company's
competitors could result in price reductions that would adversely affect the
Company's business, financial condition, and results of operations, as would
the introduction of new technologies which render the Company's manufacturing
process technology less competitive or obsolete.

GOVERNMENTAL REGULATIONS

     The Company's operations are subject to certain foreign, federal, state
and local regulatory requirements relating to environmental, waste management
and health and safety matters.  Management believes that the Company's business
is operated in material compliance with all such regulations.  The cost to the
Company of such compliance to date has not materially affected the Company's
business, financial condition or results of operations.  However, there can be
no assurance that violations will not occur in the future as a result of human
error, equipment failure or other causes.  The Company cannot predict the
nature, scope or effect of environmental legislation or regulatory requirements
that could be imposed or how existing or future laws or regulations will be
administered or interpreted.  Compliance with more stringent laws or
regulations, as well as more vigorous enforcement policies of regulatory
agencies, could require substantial expenditures by the Company and could
adversely affect the Company's business, financial condition and results of
operations.

BACKLOG

     The Company's backlog as of April 30, 1997 was approximately $38,108,380.
Backlog consists of contracts or purchase orders with delivery dates scheduled
within the next twelve months.  The Company currently expects to ship
substantially all of the April 30, 1997 backlog by the end of the 1998 fiscal
year.  Backlog as of April 30, 1996 totaled 


                                      9
                                      
<PAGE>   10


$35,029,850.  Variations in the magnitude and duration of contracts and
purchase orders received by the Company and delivery requirements generally may
result in substantial fluctuations in backlog from period to period.  Because
customers may cancel or reschedule deliveries, backlog may not be a meaningful
indicator of future financial results.

EMPLOYEES

     The Company employed approximately 1,461 people as of April 30, 1997,
including 31 engaged in engineering, 1,315 in manufacturing and 115 in
administrative and marketing functions.

     The Company has a labor contract with Production Workers Union Local No.
10, AFL-CIO, covering the Company's workers in Elk Grove Village, Illinois
which expires on November 30, 1997.  The Company's Mexican subsidiary has a
labor contract with Sindicato De Trabajadores de la Industra Electronica,
Similares y Conexos del Estado de Coahuila, C.T.M. covering the Company's
workers in Acuna, Mexico which expires on January 15, 1998.

     Since the time the Company commenced operations, it has not experienced
any work stoppages.  The Company believes its relations with both unions and
its other employees are good.


ITEM 2. PROPERTIES

     The Company, in combination with its wholly-owned subsidiary and
affiliate, has manufacturing facilities located in Elk Grove Village, Illinois,

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

CAUTIONARY NOTE:

     The following discussion provides an analysis of the Company's financial
condition and results of operations, and should be read in conjunction with the
Selected Consolidated Financial Data and the Consolidated Financial Statements
of the Company, and the Notes thereto, appearing in this Annual Report on Form
10-K, as well as in conjunction with the cautionary note concerning
forward-looking information which appears at the beginning of Item 1.

OVERVIEW

     The Company is an independent contract manufacturer of electronic
components, printed circuit board assemblies, and box-build (completely
assembled) electronic products.  Included among the wide range of services the
Company offers its customers are (1) manual and automatic assembly and testing
of customer products, (2) material sourcing, procurement and control, (3)
design, manufacturing and test engineering support, (4) warehousing and
shipment services, and (5) assistance in obtaining product approvals from
governmental and other regulatory bodies.  The Company provides these services
through facilities located in North America and the Far East.

     During the three fiscal year period ended April 30, 1997 revenues, net
income and earnings per share increased at compounded annual rates of 39%, 31%,
and 27%, respectively.  To date, the Company has accomplished this growth
primarily by satisfying the growing demands of the Company's existing customers
for its products and services, as well by targeting new customers in industries
and markets that the Company believes will undergo substantial future growth.

     The Company believes that recent trends in the Electronic Manufacturing
Services (EMS) industry have created additional opportunities for the Company
to market its products and services.  Such trends include new and emerging
markets for electronic components, greater demand for complex electronic
products, consolidation in the EMS industry, increasing market penetration by
EMS providers, the sale of captive OEM plants, an increased emphasis on quality
assurance and a reduction in the vendor base utilized by OEMs.

     Sales volume and gross profit margins can vary considerably among
customers and products depending on the type of services rendered by the
Company.  Specifically, variations in orders for turnkey services versus
consignment services and variations in the number of orders for products with
high raw material costs can lead to significant fluctuations in the Company's
operating results.  Further, customers' orders can be delayed, rescheduled or
canceled at any time, which can significantly impact the



                                       15


<PAGE>   16

operating results of the Company.  In addition, the ability to replace such
delayed or lost sales in a short period of time cannot be assured.

     As a manufacturing company, the Company includes all fixed manufacturing
overhead in cost of goods sold.  The inclusion of fixed manufacturing overhead
in cost of goods sold magnifies the fluctuations in gross profit margin
percentages caused by fluctuations in net sales and capital expenditures.
Specifically, fluctuations in the mix of consignment and turnkey contracts
could have an effect on the cost of goods sold and the resulting gross profit
as a percentage of net sales.  Consignment orders require the Company to
perform manufacturing services on components and other materials supplied by a
customer, and the Company charges only for its labor, overhead and
manufacturing costs plus a profit.  In the case of turnkey orders, the Company
provides, in addition to manufacturing services, the components and other
materials used in assembly.  Turnkey contracts, in general, have a higher
dollar volume of sales for each given assembly, owing to inclusion of the cost
of components and other materials in net sales and cost of goods sold.
However, turnkey contracts typically have lower gross margins due to this large
material content which are competitively priced.   Historically, more than 90%
of the Company's sales have been from turnkey orders.

     In June 1995, the Company signed a three-year exclusive manufacturing
agreement with NSI relating to the production of carbon monoxide detection
systems.  Sales to NSI have accounted for a significant percentage of the
Company's net sales in fiscal 1996 and 1997, and the Company expects sales to
NSI will be significant in fiscal 1998.

RESULTS OF OPERATIONS:

FISCAL YEAR ENDED APRIL 30, 1997 COMPARED
TO FISCAL YEAR ENDED APRIL 30, 1996

     Net sales for fiscal year 1997 were $87,216,343 compared to $69,558,384
for fiscal year 1996.  The 25% increase in net sales was due to sales to new
and existing customers primarily in the consumer electronics, gaming and
fitness industries.  NSI accounted for approximately $25,952,000 or 29.8% of
the Company's fiscal 1997 net sales compared to $19,605,000 or 28.2% in fiscal
1996. The volatility of NSI orders may cause the Company's revenues and
earnings to fluctuate significantly on a seasonal basis.

     Gross profit  increased from $10,142,298 in fiscal year 1996 to
$12,639,082 in fiscal year 1997.  Gross profit as a percent of net sales was
14.5% and 14.6% for fiscal 1997 and 1996, respectively.

     Selling and administrative expenses increased from $4,943,478 in fiscal
year 1996 to $5,961,184 in fiscal year 1997.  The increase is due to the
increase in sales commissions attributable to the increase in net sales.  In
addition, insurance expense increased for general insurance requirements and
increased levels of product liability


                                      16

                                       
<PAGE>   17

insurance.  Additional customer service and material procurement personnel were
added to support the growth of the Company.  Selling and administrative
expenses as a percent of net sales decreased for the fiscal year ended April
30, 1997 to 6.8% from 7.1% for the year ended 1996.

     Interest expense increased in fiscal 1997 to $1,846,928 from $1,630,238 in
fiscal 1996.  The overall increase was primarily due to the higher outstanding
balance on the Company's line of credit.  Interest expense as a percent of net
sales decreased from 2.3% in fiscal 1996 to 2.1% in fiscal 1997.

     Income tax expense increased from $1,385,000 in fiscal year 1996 to
$1,905,584 in fiscal year 1997.  The effective tax rate for fiscal years 1997
and 1996 was 36.9%.

     As a result of the foregoing, net income increased 37.5% from $2,366,822
in fiscal 1996 to $3,255,058 in fiscal 1997.  Primary earnings per share for
the year ended April 30, 1997 was $1.11 compared to $ .86 in fiscal 1996.
Fully diluted earnings per share for fiscal 1997 was $1.08.

QUARTERLY RESULTS AND SEASONALITY

     Historically, the Company's highest levels of sales are achieved in its
second and third quarters.  This is due to the seasonal nature of several of
the Company's customers.  In particular, NSI's sales of carbon monoxide
detectors generally coincides with the heating season, and several other
customers have sales tied to the holidays.  This trend has caused the Company
to experience revenue and earnings seasonality, resulting in generally stronger
second and third quarters in each fiscal year.  Regardless of seasonal
fluctuations, there can be no assurance that the Company will be profitable in
any particular quarter.

     The Company's results of operations have varied significantly and may
continue to fluctuate from quarter to quarter.  Operating results are affected
by a number of factors, including timing of orders from and shipments to major
customers, availability of materials and components, the volume of orders as
related to the Company's capacity, timing of expenditures in anticipation of
future sales, the gain or loss of significant customers and variations in the
demand for products in the industries served by the Company's services.  A
significant portion of the Company's expenses are relatively fixed in nature
and planned expenditures are based in part on anticipated orders.  The
inability to adjust expenditures quickly enough to compensate for a decline in
net sales may magnify the adverse impact of such decline in the Company's
results of operations.  The Company's customers generally require short
delivery cycles.  In the absence of substantial backlog, quarterly sales and
operating results depend on the volume and timing of orders received during the
quarter which can be difficult to forecast.  In addition, variations in the
size and delivery schedules of purchase orders received by the Company, as well
as changes in customers' delivery requirements or the rescheduling or
cancellations of orders and commitments, may result in substantial fluctuations
in

                                      17

<PAGE>   18

backlog from period to period.  Accordingly, the Company believes that backlog
cannot be considered a meaningful indicator of future operating results.

FISCAL YEAR ENDED APRIL 30, 1996 COMPARED
TO FISCAL YEAR ENDED APRIL 30, 1995

     Net sales for fiscal year 1996 were $69,558,384 compared to $45,344,903
for fiscal year 1995.  The 53% increase in net sales was primarily due to sales
to a new customer, NSI.  NSI accounted for approximately $19,605,000 or 28.2% of
the Company's fiscal 1996 net sales.  The Company anticipates NSI will account
for a significant percentage of the Company's net sales in fiscal 1997. Sales to
NSI are expected to be seasonal due to the nature of the product and the Company
anticipates strong sales to NSI in the fall and winter months.  However, the
Company did not start manufacturing for NSI until August 1995 and their market
is an emerging market which could lead to volatility in its forecast.  The
volatility of NSI orders may cause the Company's revenues and earnings to
fluctuate significantly on a seasonal basis.  Also, contributing to the increase
in net sales for fiscal 1996 were sales to existing customers in the fitness and
telecommunications industries and several new customers.

     Gross profit  increased from $8,411,771 in fiscal year 1995 to $10,142,298
in fiscal year 1996.  Gross profit as a percent to net sales decreased from
18.6% in fiscal 1995 to 14.6% in fiscal 1996.  The decrease , as a percent of
net sales, is primarily due to lower gross margin on sales to NSI which were
offered due to the high volume.

     Selling and administrative expenses increased from $4,379,987 in fiscal
year 1995 to $4,943,478 in fiscal year 1996.  The increase is due to the
increase in sales commissions attributable to the increase in net sales.  In
addition, employees were hired in the customer service and material procurement
departments to support the additional revenue volume.  Also, additional
insurance expense was incurred due to the NSI contact and approximately $48,000
was paid to the Hacienda for transfer pricing taxes in Mexico.  Selling and
administrative expenses as a percent of net sales for the fiscal year ended
April 30, 1996 were 7.1% compared to 9.7% for the prior fiscal year.  In
addition to the increase in net sales, the decrease in selling and
administrative as a percent to net sales was partially the result of reversing
a $300,000 accrual for payables to creditors of a predecessor company.

     Interest expense increased in fiscal year 1996.  Interest expense
increased from $743,374 or 1.6% of net sales in 1995 to $1,204,321 or 1.7% of
net sales in fiscal 1996.  The overall increase is primarily due to the higher
outstanding balance on the line of credit and higher interest rates.
     Income before income tax expense increased from $3,031,611 in fiscal year
1995 to $3,751,822 in fiscal year 1996.  Net income increased from $1,890,611
in fiscal year 1995 to $2,366,822 in fiscal year 1996 which resulted in net
earnings per share of $ 0.86 in fiscal year 1996 compared to $0.69 in fiscal
1995. Income tax expense in fiscal year 1996 was $1,385,000 compared to
$1,141,000 in the prior fiscal year.

LIQUIDITY AND CAPITAL RESOURCES:

     In fiscal 1997 the Company financed its growth and operations through
cash flow  generated by profitable operations and borrowings from its secured
lender.  The Company had working capital of $21,648,985 at April 30, 1997 and
$18,284,525 at April 30, 1996.  The increase in working capital generally
parallels the Company's increase in inventory, which resulted from an increase
in orders.

     In fiscal 1997 the primary sources of cash provided by operations were
net income and borrowings from its secured lender.  In fiscal year 1997 the net
cash provided by operations of  $1,457,663 included net income of $3,255,058
which was decreased by $2,731,550 for net cash used for inventories.

     The Company has a credit arrangement in place which is comprised of a
revolving loan facility and a term loan.  Under the revolving loan facility,
the Company may borrow certain percentages of the Company's accounts receivable
and inventory, up to a maximum of $25.0 million.  At April 30, 1997, based upon
those percentages, there was approximately $1,297,000 of unused credit
available under the revolving loan facility.  Outstanding borrowings under the
revolving loan facility bear interest at the Company's option of either the
London Interbank Offered Rate ("LIBOR") plus 2.0% or the bank's prime rate of
interest.  The revolving loan facility is collateralized under a loan and
security agreement by substantially all of the domestically located assets of
the Company.  The agreement contains certain financial covenants pertaining to
the maintenance of tangible net worth and net income.  The revolving loan
facility matures on September 30, 1998, and automatically renews from year to
year thereafter, unless otherwise terminated at the option of the Company or
the lending bank.  The maximum amount which could be borrowed under the term
loan was $277,776 which was the outstanding balance at April 30, 1997.  The
amount outstanding under the term loan is collateralized by some of the
Company's machinery and equipment located in the United States and is payable
in 60 monthly installments of approximately $13,890 plus accrued interest.  The
outstanding principal under the term loan bears interest at the Company's
option of either the LIBOR plus 2.0% or the bank's prime rate of interest.  The
interest rates were renegotiated in June of 1996.  The interest rate for
outstanding borrowings on the revolving loan facility and term loan facility
decreased from prime plus .5% to the lower of LIBOR plus 2.0% or the bank's
prime rate of interest.

     To the extent that the Company provides the funds necessary to run its
Mexican operations, the amount of funds available for use in the Company's
domestic operations may be depleted.  The funds, which ordinarily derive from
the Company's cash from operations and borrowings under its revolving credit
facility, equal approximately $5,970,000 for a typical 12 month period.  The
Company provides funding in U.S. dollars, which are exchanged for pesos as
needed.

     The Company is a 42.5% limited partner in SMTU, a California limited
partnership, based in Fremont, California.  SMTU has a negative working capital
of approximately $1,161,000 at April 30, 1997, and an accumulated deficit of
approximately $1,187,000.  From the formation of SMTU in September 1994 until
January 1995, SMTU had no sales.  Since fiscal 1995 sales have increased so
that SMTU was approaching profitability during 1997.  Management of SMTU
expects sales to increase further in 1998 and also expects these sales will
lead to overall profitability.  At April 30, 1997, SMTU was in violation of
various covenants under their revolving line of credit.  SMTU's management
expects to be able to renegotiate these covenants to prevent noncompliance and
to obtain waivers for all covenants violated in fiscal 1997.

     On August 1, 1995 the Company entered into a limited partnership agreement
forming Lighting Components L.P. ("LC").  The Company owns approximately 12% of
LC , which distributes a variety of electronic and molded plastic components
for use in the sign and lighting industries.  At April 30, 1997 the Company had
invested $230,000 in the venture.  This includes $60,000 in subordinated
debentures and $170,000. LC and the Company have also executed a manufacturing
agreement whereby the Company will perform manufacturing services for LC as
long as the Company remains competitive in price and quality.

     In fiscal year 1996 the Company financed its growth and operations by
borrowings from its secured lender.  The Company had working capital of
$18,859,747 at April 30, 1996 and $13,292,754 at April 30, 1995.  The increase
in working capital generally parallels the Company's increase in inventory and
accounts receivable, which resulted from an increase in net sales.

     The impact of inflation for the past three fiscal years has been minimal.

                         Report of Independent Auditors

The Board of Directors and Stockholders
SigmaTron International, Inc.

We have audited the accompanying consolidated balance sheets of SigmaTron
International, Inc., as of April 30, 1997 and 1996, and the related
consolidated statements of income, equity, and cash flows for each of the three
years in the period ended April 30, 1997.  Our audits also included the
financial statement schedule listed in the Index at Item 14(a).  These
financial statements and schedule are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements and schedule 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 our audits provide a reasonable basis for
our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
SigmaTron International, Inc., at April 30, 1997 and 1996, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended April 30, 1997, in conformity with generally accepted accounting
principles.  Also, in our opinion, the related financial statement schedule,
when considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

                   Notes to Consolidated Financial Statements


1. Description of the Business

SigmaTron International, Inc. (the Company) was incorporated on November 16,
1993. The Company is an independent contract manufacturer of electronic
components, printed circuit board assemblies, and completely assembled
(boxbuild) electronic products.  Included among the wide range of services the
Company, its wholly owned subsidiary, Standard Components de Mexico, S.A. and
its affiliate, SMT Unlimited L.P. (SMTU), offer their customers are (1) manual
and automatic assembly and testing of products; (2) material sourcing,
procurement, and control; (3) design, manufacturing, and test engineering
support; (4) warehousing and shipment services; and (5) assistance in obtaining
product approval from governmental and other regulatory bodies.  The Company
provides these services through an international network of facilities located
in North America and the Far East.

2. Summary of Significant Accounting Policies

Consolidation Policy

The consolidated financial statements include the accounts and transactions of
the Company and its wholly owned subsidiary, Standard Components de Mexico,
S.A.  Significant intercompany accounts and transactions have been eliminated
in consolidation.  Investments in affiliates which are at least 20% owned are
carried at cost plus equity in undistributed earnings or losses since
acquisition.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that effect the amounts reported in the financial statements and accompanying
notes.  Actual results could differ from those estimates.

Inventories

Inventories are stated at the lower of cost or market.  Cost is determined by
the first in, first out (FIFO) method.

Machinery and Equipment



                                     F-10

<PAGE>   36

Machinery and equipment are stated at cost.  The Company provides for   
depreciation and amortization using the straight-line method over the estimated
useful life of the asset.

           Notes to Consolidated Financial Statements (continued)

2.  Summary of Significant Accounting Policies (continued)

Intangible Assets

Intangible assets consist primarily of deferred financing costs and
organizational costs.  These items are being amortized by the straight-line
method over the estimated useful lives of the assets, which range from one to
five years.

Income Taxes

The liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.

Earnings Per Share

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings Per Share, which is required to be adopted on December 31, 1997.
At that time, the Company will be required to change the method currently used
to compute earnings per share and to restate all prior periods.  Under the new
requirements for calculating primary earnings per share, the dilutive effect of
stock options will be excluded.  The impact is expected to result in a $.05
increase in primary earnings per share for the year ended April 30, 1997 and no
effect on primary earnings per share for the years ended April 30, 1996 and
1995.  The impact of Statement 128 on the calculation of fully diluted earnings
per share for 1997 is not material.

Fair Value of Financial Instruments

The Company's financial instruments include trade accounts receivable, notes
receivable, long-term receivables, accounts payable, notes payable, capital
lease obligations, and accrued expenses.  The fair values of all financial
instruments were not materially different from their carrying values.

Revenue Recognition

The Company recognizes revenue at the time goods are shipped.

5.  Investment and Advances With Affiliate

The Company's investment in affiliate consists of a 42.5% ownership             
interest in SMTU, which was formed on September 15, 1994, in Fremont,
California, as a joint venture to provide surface mount technology assembly
services primarily to electronic original equipment manufacturers.  During
fiscal year 1995, the Company invested $49,500 in exchange for a 45% limited
partnership interest in SMTU and $2,500 in SMT Unlimited, Inc. (SMT, Inc.),
which is the general partner of SMTU, in exchange for 50% of its capital stock. 
During fiscal year 1997, the Company sold 2.5% of its interest to a key
employee of SMTU.  One of the limited partners of SMTU is also an equal
shareholder of SMT, Inc., along with the Company.  The Company made advances to
SMTU in exchange for subordinated debentures in the face amount of $100,000,
$50,000, and $600,000 in 1997, 1996, and 1995, respectively.  In 1996, the
Company also made advances to SMTU in exchange for promissory notes in the face
amount of $300,000.  These promissory notes were converted into subordinated
debentures during 1997. Debentures totaling $650,000 outstanding at April 30,
1997 bear interest at 8%, and are to be repaid on December 31, 1999.  The
remaining $400,000 of these debentures bear interest at 12% and are to be
repaid on December 31, 2001.  The Company guarantees lease payments of
approximately $1,831,000 for SMTU.  The Company has been indemnified by one of
the other limited partners in the amount of $915,500 for the guaranteed lease
payments.  SMTU pays the Company a $12,500 monthly administrative fee for
administrative services.
        
SMTU has negative working capital of approximately $1,161,000 at April  30,
1997, and an accumulated deficit of approximately $1,187,000 at April 30, 1997.
From the formation of SMTU in September 1994 until January 1995, SMTU had no
sales.  Since fiscal 1995, sales have increased so that SMTU was achieving near
break-even profitability during 1997.  Management of SMTU expects sales to
increase further in 1998 and also expects these sales will lead to overall
profitability.  At April 30, 1997, SMTU was in violation of various covenants
under their revolving line of credit.  SMTU's management expects to be able to
renegotiate these covenants to prevent future noncompliance and to obtain
waivers for all covenants violated in 1997.

The Company subleased the machinery and equipment relating to six of the above
capital lease agreements to its affiliate, SMTU.  These sublease agreements
contain the same maturity dates as the original underlying lease agreements.
The effective interest rates on these leases are approximately 2% higher than
the effective interest rates (ranging from 8.25% to 10.12%) implicit in the
original lease to cover various administrative expenses of the Company.  The
equipment lease receivables are collateralized by the underlying machinery and
equipment.  Management believes the machinery and equipment would be able to be
readily used in the Company's manufacturing operations if necessary.

14.  Warrants and Stock Options (continued)

On February 8, 1994, the stockholders of the Company approved the formation of
two stock option plans (Option Plans) under which certain members of management
and outside nonmanagement directors may acquire up to 698,500 shares of Common
Stock of the Company.  The Option Plans are interpreted and administered by the
Compensation Committee (the Committee).  The maximum term of options granted
under the Option Plans generally are 10 years.  Options granted under the
Option Plans are either incentive stock options or nonqualified options.
Options forfeited under the Option Plans are available for reissuance.

The Committee approved grants to certain members of the Company's management
effective February 9, 1994, of options to purchase all of the 625,000 shares of
Common Stock available under the Plan at an exercise price equal to $7.00.  Of
the options granted to management, options to purchase up to 200,000 shares of
Common Stock will vest at a rate of 20% each year following the date of grant,
provided the optionee remains an employee of the Company.  As of April 30, 1997
and 1996, management vested in options to purchase 120,000 and 80,000 shares,
respectively.  The remaining options to purchase up to 425,000 shares of Common
Stock will vest only on the Company's attainment of certain earnings per share
levels over the five fiscal years beginning with fiscal year 1995.  None of
these options became exercisable during fiscal year 1997, 1996, or 1995 as the
earnings per share level goal was not met, and options to purchase 100,000,
75,000, and 50,000 shares were forfeited in 1997, 1996, and 1995, respectively.
On June 11, 1997, options to purchase up to 425,000 shares of common stock
were canceled and return to the pool of ungranted options to be granted as
service based options at a date to be determined by the committee.

The Company also has a stock option plan for the benefit of directors who are
not salaried employees of the Company or full-time consultants to the Company.
Seventy-three thousand-five-hundred shares of Common Stock were reserved for
issuance upon exercise of such options.  Each eligible director in office at
the adjournment of the first three annual meetings of stockholders held after
February 9, 1994, was granted an option to purchase 3,500 shares of the
Company's Common Stock at an exercise price per share equal to the fair market
value of a share of the Company's Common Stock on the date of grant.  As of
April 30, 1997, all options reserved for issuance under this plan have been
granted.  An option may be exercised at any time within 10 years from the date
of grant.  On June 11, 1997, a new outside nonmanagement director option plan
was adopted subject to shareholder approval, to grant options to purchase up to
105,000 shares of common stock in a manner similar to the old plan.

14.  Warrants and Stock Options (continued)

The Company has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees (APB 25), in accounting for its
employee stock options because, as discussed below, the alternative fair value
accounting provided for under FASB statement No. 123, Accounting for
Stock-Based Compensation, requires the use of option-valuation models that were
not developed for use in valuing employee stock options.  Under APB 25, because
the exercise price of the Company's employee stock options approximates the
market price of the underlying stock on the date of grant, no compensation
expense is recognized.  Pro forma information regarding net income and earnings
per share is required by Statement 123  as if the Company has accounted for its
employee stock options granted subsequent to December 31, 1994, under the fair
value method of that Statement.  For purposes of pro forma disclosures, the
estimated fair value of the options is amortized to expense over the options
vesting period.

The Company's pro forma information follows:

Option valuation models require the input of highly subjective assumptions.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate in management's
opinion, the existing method does not

15.  Net Income Per Common and Common Equivalent Share

Net income per common and common equivalent share is computed based upon the
weighted-average number of shares outstanding.  When dilutive, stock options
and warrants are included as share equivalents using the treasury stock method.
The 425,000 shares reserved for issuance under the management stock option
plan are not considered common stock equivalents in 1997, 1996, and 1995 as the
earnings per share goals were not reached. Fully diluted net income per common
and common equivalent share is not materially different from primary net income
per common and common equivalent share in 1996 and 1995.

16.  Subsequent Event

On July 1, 1997, the Committee approved grants of options to certain employees
and members of the Company's management to purchase 352,000 shares of common
stock at an exercise price equal to $12.25.  These options will vest at a rate
of 20% each year following the date of grant, provided the optionee remains an
employee of the Company.

ARTICLE 2. ADVANCES AND TERM LOANS
        
     Section 2.1. Requests for an Advance.  On the effective date of this
Agreement, the principal balance of advances outstanding under the revolving
line of credit established under the Original Loan Agreement is $17,203,402.89
(the "Original Revolving Loans").  By signing below, each Lender agrees to
purchase or sell, as the case may be, interests in the Original Revolving Loans
so that after giving effect thereto each Lender holds its pro rata



                                     -9-

<PAGE>   15

share (based on the proportion which such Lender's Revolving Loan Commitment
bears to the aggregate amount of the Revolving Loan Commitments) of the
Original Revolving Loans; all of which shall constitute "Advances" under this
Agreement which shall bear interest, mature, and otherwise be subject to the
terms and conditions of this Agreement and the other Transaction Documents,
secured by the Collateral and all Security Interests therein.  From time to
time on and after the date of this Agreement, Debtor may make a written or oral
request for an Advance, so long as the sum of the aggregate principal balance
of outstanding Advances and the requested Advance does not exceed the Borrowing
Capacity as then computed; and each Lender, severally and not jointly, shall
make available to Debtor such Lender's pro rata share (based on the proportion
which such Lender's Revolving Loan Commitment bears to the aggregate amount of
Revolving Loan Commitments) of such requested Advance, provided that (i) the
Borrowing Capacity would not be so exceeded; (ii) there has not occurred an
Event of Default or an event which, with notice or lapse of time or both, would
constitute an Event of Default; (iii) all representations and warranties
contained in this Agreement and in the other Transaction Documents are true and
correct on the date such requested Advance is made as though made on and as of
such date; and (iv) no Lender's Revolving Loan Commitment would be exceeded.
Notwithstanding any other provision of this Agreement, Agent may from time to
time reduce the percentages applicable to the Receivables Borrowing Base and
the Inventory Borrowing Base as they relate to amounts of the Borrowing
Capacity to the extent Agent determines in its reasonable judgment, that there
has been a material change in circumstances related to any or all Receivables
or Inventory from those circumstances in existence on or prior to the date of
this Agreement or in the financial or other condition of Debtor.  Each oral
request for an Advance shall be conclusively presumed to be made by a person
authorized by Debtor to do so, and the making of the Advance to Debtor as
hereinafter provided shall conclusively establish Debtor's obligation to repay
the Advance.

     Section 2.2. Procedures for Advances.  (a) Manner and Disbursement of
Advances.  Debtor shall give written or telephonic notice to Agent (which
notice shall be irrevocable once given and, if given by telephone, shall be
promptly confirmed in writing) by no later than 11:00 a.m. (Chicago time) on
the date Debtor requests that any Advance be made to it, and, except in the
case of Advances made under Section 2.2(b), Agent shall promptly notify each
Lender of Agent's receipt of each such notice.  Each such notice shall specify
the date of the Advance requested (which must be a Business Day) and the amount
of such Advance.  Each Advance shall initially constitute part of the
applicable Prime Rate Portion except to the extent Debtor has otherwise timely
elected that such Advance constitute part of a LIBOR Portion as provided in
Item 18 of the Schedule.  Not later than 1:00 p.m. (Chicago time) on the date
specified for any Advance hereunder, each Lender shall make the proceeds of its
pro rata share of such Advance available to Agent at such place designated by
Agent in immediately available funds.  Subject to the provisions of Section 2.1
above, the proceeds of each Advance shall be made available to Debtor in the
manner agreed to by Debtor and Agent in writing or, absent any such agreement,
as determined by Agent upon receipt by Agent from each Lender of its pro rata
share of such Advance.  Unless Agent shall have been notified by a Lender prior
to 12:00 noon (Chicago time) on the date an Advance is to be made that such
Lender does not intend to make its pro rata share of such Advance available to
Agent, Agent may assume that such Lender has made such share available to



                                     -10-

<PAGE>   16

Agent on such date and Agent may in reliance upon such assumption make 
available to Debtor a corresponding amount.

     (b) Funding of Advances by Agent.  Notwithstanding the notice requirements
set forth in Section 2.2(a) above, but otherwise in accordance with the terms
and conditions of this Agreement, Agent may, in its sole discretion without
conferring with Lenders but on their behalf, make Advances to Debtor in an
amount requested by Debtor.  Each Lender's obligation to fund its pro rata
share of any such Advance made by Agent will commence on the date such Advance
is actually so made by the Agent.  However, until the date on which the
Settlement of such Advance is required in accordance with Section 2.7, such
obligation of Lender shall be satisfied by Agent's making of such Advance.
Debtor acknowledges and agrees that the making of such Advances by Agent under
this Section shall, in each case, be subject in all respects to the provisions
of this Agreement as if each such Advance were made in response to a notice
requesting such Advance made in accordance with Section 2.2(a) above, including
without limitation the limitations set forth in Section 2.1.  All actions taken
by Agent pursuant to the provisions of this Section shall be conclusive and
binding on Debtor.  Any Advances made and maintained by Agent pursuant to this
Section shall constitute part of the applicable Prime Rate Portion.
Notwithstanding anything herein to the contrary, prior to the Settlement with
any Lender of any Advance funded by Agent under this Section, interest payable
on such Advance otherwise allocable to such Lender shall be for the sole
account of Agent and payment of principal on such Advance otherwise allocable
to such Lender shall be for the sole account of Agent.

     (c) Late Payment By Lender.  If an amount due Agent from a Lender to fund
such Lender's pro rata share of an Advance, as required by Section 2.2(a)
hereof, or to effect the Settlement of any Advance, as required of Section 2.7
hereof, is not in fact made available to Agent by such Lender when due and
Agent has made the corresponding amount available to Debtor, Agent shall be
entitled to receive such amount from such Lender forthwith upon Agent's demand,
together with interest thereon in respect of each day during the period
commencing on the date such amount was made available to Debtor and ending on
but excluding the date Agent recovers such amount at a rate per annum equal to
the effective rate charged to Agent or its affiliates for overnight federal
funds transactions with member banks of the federal reserve system for each day
as determined by Agent (or in the case of a day which is not a Business Day,
then for the preceding day).  If such amount is not received from such Lender
by Agent immediately upon demand, Debtor will, on demand, repay to Agent the
proceeds of the Advance attributable to such Lender with interest thereon at a
rate per annum equal to the interest rate applicable to the relevant Advance,
but (i) without such payment being considered a payment or prepayment of a
LIBOR Portion (so that Debtor will have no liability under Item 18(h) of the
Schedule with respect to such payment) and (ii) without such payment impairing
or otherwise prejudicing Debtor's claims and other rights against such Lender.

     Section 2.3. Establishment of Reserves.  Agent may, at any time and from
time to time, in its reasonable judgment, establish reserves against the
Receivables or the Inventory of Debtor.  The amount of such reserves shall be
subtracted from the Receivables



                                     -11-

<PAGE>   17

Borrowing Base or Inventory Borrowing Base, as applicable, when calculating the
amount of the Borrowing Capacity.

     Section 2.4. Letters of Credit.  (a) Requests for Letters of Credit.  At
the request of Debtor, and upon execution of Letter of Credit documentation
satisfactory to the Hongkong Shanghai Banking Corporation or another bank
acceptable to Agent, Agent, within the limits of the Borrowing Capacity as then
computed, shall guaranty Letters of Credit issued from time to time by the
Hongkong Shanghai Banking Corporation or such other bank acceptable to Agent
for the account of Debtor in an amount not exceeding in the aggregate at any
one time outstanding the amount set forth in Item 9 of the Schedule.  The
Letters of Credit shall be on terms mutually acceptable to Agent and Debtor and
no Letters of Credit shall have an expiration date later than the termination
date of this Agreement.  An Advance in an amount equal to any amount paid by
Agent on such guaranty shall be deemed made to Debtor, without request
therefor, immediately upon any payment by Agent on such guaranty, which Advance
shall be deemed part of the applicable Prime Rate Portion.  In connection with
the issuance of any guaranty of a Letter of Credit, Debtor shall pay to Agent
for the benefit of the Lenders in accordance with their pro rata share thereof
(based on the proportion which the relevant Lender's Revolving Loan Commitment
bears to the aggregate amount of Revolving Loan Commitments), the fees set
forth in Item 19 of the Schedule and to the issuer of the relevant Letter of
Credit all fees charged by such issuer.

     (b)  Participations in Letters of Credit.  Each Lender shall participate
on a pro rata basis (based on the proportion which the relevant Lender's
Revolving Loan Commitment bears to the aggregate amount of Revolving Loan
Commitments) in the Letters of Credit, and the guaranty obligations arising in
connection therewith, and in any deemed Advance made under Section 2.4(a)
above, which participation shall arise on the date of this Agreement with
respect to all outstanding letters of credit guaranteed by HBLI under the
Original Loan Agreement and listed on Exhibit C and which participation shall
automatically arise with respect to each Letter of Credit issued after the date
of this Agreement upon the issuance of each such Letter of Credit.  Each Lender
unconditionally agrees that in the event an Advance is deemed to be made to
Debtor under the terms of Section 2.4(a) above, then in that event such Lender
shall pay to Agent such Lender's pro rata share of such Advance (on the next
Settlement Date or, if sooner required by Agent, by 1:00 p.m. (Chicago time)
upon Agent's demand if such demand is given to such Lender by 11:00 a.m.
(Chicago time) on any Business Day or, if such demand is given after 11:00 a.m.
(Chicago time) on any Business Day, by 1:00 p.m. (Chicago time) on the next
Business Day), without regard to the conditions for an Advance set forth in
Section 2.1, and in return such Lender shall automatically receive an
equivalent percentage participation in each payment received in respect of the
relevant Advance, together with interest thereon as provided for herein.  The
obligations of Lenders to Agent under this subsection shall be absolute,
irrevocable and unconditional under any and all circumstances whatsoever
(except to the extent Debtor is relieved from its obligation to reimburse Agent
for a drawing under a Letter of Credit because of Agent's gross negligence or
willful misconduct) and shall not be subject to any set-off, counterclaim or
defense to payment which any Lender may have or have had against Debtor, Agent,
any other Lender or any other party whatsoever.  In the event that any Lender
fails to honor its obligation to reimburse Agent for its pro rata share



                                     -12-

<PAGE>   18

of the amount of any such draft, then in that event (i) the defaulting Lender
shall have no right to participate in any recoveries from Debtor in respect of
such Advance and (ii) all amounts to which the defaulting Lender would
otherwise be entitled under the terms of this Agreement or any other
Transaction Document shall first be applied to reimbursing Agent for the
defaulting Lender's portion of the Advance, together with interest thereon as
provided for herein.  Upon reimbursement to Agent (pursuant to clause (ii)
above or otherwise) of the amount advanced in respect of the defaulting
Lender's share of the Advance together with interest thereon, the defaulting
Lender shall thereupon be entitled to its participation in Agent's right of
recovery against Debtor in respect of the Advance made by Agent.

     Section 2.5. Term Loans.  On the effective date of this Agreement, the
principal balance of the term loan outstanding under the Original Loan
Agreement is $291,665.00 (the "Original Term Loan").  By signing below, each
Lender agrees to purchase or sell, as the case may be, interests in the
Original Term Loan so that after giving effect thereto the outstanding
principal amount of the Original Term Loan owing to each Lender equals such
Lender's Term Loan Commitment (the Original Term Loan held by each Lender
immediately after giving effect thereto being referred to herein individually
as such Lender's "Term Loan" and collectively all Term Loans made by Lenders
being referred to herein as the "Term Loans"); and the Term Loans shall
thereafter bear interest, mature, and otherwise be subject to the terms and
conditions of this Agreement and the other Transaction Documents, secured by
the Collateral and all Security Interests therein.  Debtor hereby promises to
make principal payments on the Term Loans in monthly principal installments as
follows:  $13,889.00 in the aggregate on March 1, 1997, and a like amount on
the same day of each month thereafter, with a final installment of all
principal not sooner paid on the Term Loans due on December 1, 1998, the final
maturity thereof.  All such principal payments on the Term Loans shall be
applied to the Lenders pro rata based on the proportion which the outstanding
principal amount of each Lender's Term Loan bears to the aggregate outstanding
principal amount of the Term Loans prior to giving effect to such payment.

     Section 2.6. Promissory Notes.  (a) The pro rata share of all Advances
made by a Lender (including Advances in which such Lender participates in
pursuant to the terms of Section 2.7) shall be evidenced by a single Revolving
Note of Debtor issued to such Lender (individually a "Revolving Note" and
collectively for all Lenders the "Revolving Notes"), each such Revolving Note
to be payable to the order of the applicable Lender in the principal amount of
its Revolving Loan Commitment and otherwise in the form of Exhibit A-1 hereto.

     (b) The Term Loan made by a Lender shall be evidenced by a single Term
Note of Debtor issued to such Lender (individually a "Term Note" and
collectively for all Lenders the "Term Notes"), each such Term Note to be
payable to the order of the applicable Lender in the principal amount of its
Term Loan Commitment and otherwise in the form of Exhibit A-2 hereto.





                                     -13-

<PAGE>   19

     (c) All loans or advances made against the Notes, the status of all
amounts evidenced by the Notes as constituting part of the applicable Prime
Rate Portion or LIBOR Portion and the rates of interest and interest periods
applicable thereto shall be recorded by the Lenders on their books and records
or, at their option in any instance, endorsed on the reverse side of the Notes.
Without regard to the principal amount of each Note stated on its face, the
actual principal amount at any time outstanding and owing by Debtor on account
thereof shall be the sum of all loans or advances then or theretofor made
thereon less all payments of principal actually received thereon.

     Section 2.7. Weekly Settlement.  (a)  In order to minimize the frequency
of transfers of funds between Agent and each Lender, Advances and repayments of
Advances and Term Loans will be settled according to the procedures described
in this Section.  Agent shall, once every seven (7) days, or sooner, if
necessary in order to afford Debtor the ability to fully utilize the Revolving
Loan Commitment of each Lender or otherwise if so elected by Agent in its
discretion, but in each case on a Business Day, (each such day being a
"Settlement Date"), distribute to each Lender a statement (the "Settlement
Report") disclosing as of the immediately preceding Business Day, the aggregate
unpaid principal balance of Advances and Term Loans outstanding as of such date
(including Advances made by the Agent under Section 2.2(b) hereof), repayments
and prepayments of principal received from Debtor with respect to the Advances
and Term Loans since the immediately preceding Settlement Report, and
additional Advances made to Debtor since the date of the immediately preceding
Settlement Report.  Each Settlement Report shall disclose the net amount (the
"Settlement Amount") due to or due from Lenders to effect a Settlement of any
Advance or Term Loan.  The Settlement Report submitted to a Lender shall be
prima facie evidence of the amount due to or from such Lender to effect a
Settlement of any Advance or Term Loan.  If the Settlement Report discloses a
net amount due from Agent to any Lender to effect the Settlement of an Advance
or Term Loan, Agent, concurrently with the delivery of the Settlement Report to
Lenders, shall transfer, by wire transfer or otherwise, such amount to such
Lender in funds immediately available to such Lender, in accordance with such
Lender's instructions.  If the Settlement Report discloses a net amount due to
Agent from any Lender to affect the Settlement of any Advance or Term Loan,
then such Lender shall wire transfer such amount, in funds immediately
available to Agent, as instructed by Agent.  Such net amount due from a Lender
to Agent shall be due by 1:00 p.m. (Chicago time) on the Settlement Date if
such Settlement Report is received before 11:00 a.m. (Chicago time) and such
net amount shall be due by 1:00 p.m. (Chicago time) on the first Business Day
following the Settlement Date if such Settlement Report is received after 11:00
a.m. (Chicago time).  Notwithstanding the foregoing, payments actually received
by Agent with respect to the following items shall be distributed by Agent to
each Lender as follows:

          (i)  any principal payment of a LIBOR Portion that is not converted or
     continued will be paid to Lenders by Agent on the same day as received;

         (ii)  as soon as possible, but in any event, within one Business Day
     after receipt thereof by Agent, payments applicable to interest on the
     Advances and Term Loans shall be paid to each Lender in proportion to its
     pro rata share thereof (based



                                     -14-

<PAGE>   20


     on the outstanding principal amount of the relevant Indebtedness owing
     to each Lender), subject to any adjustments for any Advances made by Agent
     under Section 2.2(b) hereof so that Agent alone shall receive interest on
     the Advances so made until Settlement with such Lender on such Advances
     and each Lender shall only receive interest on the amount of funds
     actually advanced by such Lender.  Each Lender's share of interest
     accruing each day on the Advances shall be based on such Lender's Daily
     Loan Balance.  For purposes hereof, the term "Daily Loan Balance" shall
     mean as of any day for any Lender, an amount calculated as of the end of
     that day by subtracting (a) the cumulative principal amount paid by Agent
     to such Lender on account of Advances from the date of this Agreement
     through and including the date as of which the Daily Loan Balance is being
     determined from (b) the cumulative principal amount advanced by such
     Lender to Agent for the benefit of Debtor to fund Advances made or
     purchased on and after the date of this Agreement through and including
     such date of determination; and

          (iii) as soon as possible, but in any event, within one Business Day
     after receipt thereof by Agent, payments applicable to the fees set forth
     in Item 19 to the Schedule and expenses payable under this Agreement,
     shall in each case be paid to each Lender as set forth in the applicable
     Section hereof.

     (b)  In the event that any bankruptcy, reorganization, liquidation,
receivership or similar cases or proceedings in which Debtor is a debtor,
prevent Agent or any Lender from making any advance to effect a Settlement
contemplated hereby, Agent or such Lender, as the case may be, will make such
dispositions and arrangements with the other Lenders with respect to the
Advances and Term Loans, either by way of purchase of participations,
distribution, pro tanto assignment of claims, subrogation or otherwise, as
shall result in each Lender holding its pro rata share of the outstanding
Advances and Term Loans.

     (c)  Payments to effect a Settlement shall be made without set-off,
counterclaim or reduction of any kind.  The failure or refusal of any Lender to
make available to Agent at the aforesaid time and place the amount of the
Settlement Amount due from such Lender (i) shall not relieve any other Lender
from its several obligation hereunder to make available to Agent the amount of
such other Lender's Settlement Amount and (ii) shall not impose upon such other
Lender any liability with respect to such failure or refusal or otherwise
increase the Loan Commitments of such other Lender.

Lender, at the offices of the Agent, the outstanding principal of Advances and
the Term Notes in full upon termination of this Agreement pursuant to Section
14.13, or acceleration of the time for payment of the Indebtedness, pursuant to

                                     -23-
<PAGE>   29


interest at a per annum rate equal to (i) 3% greater than the rate of interest
specified in Item 18 of the Schedule on the principal of Advances and on the
balance of principal remaining from time to time unpaid on the Term Notes,
whether or not past due and (ii) 3% plus the Prime Rate as in effect from time
to time on any other amounts past due under the Transaction Documents.

     (b) Interest shall be paid (i) on the first day of each month in arrears,
(ii) on termination of this Agreement, pursuant to Section 14.13, (iii) on
acceleration of the time for payment of the Indebtedness, pursuant to Section
11.2, and (iv) on the date the Indebtedness is paid in full.

     (c) Any change in the interest rate resulting from a change in the Prime
Rate shall take effect simultaneously with such change in the Prime Rate.
Interest shall be computed on the daily unpaid principal balance of Advances or
of the Term Notes, as the case may be.  Interest shall be calculated for each
calendar day at 1/360th of the applicable per annum rate which will result in
an effective per annum rate higher than that specified in Item 18 of the
Schedule.  In no event shall the rate of interest exceed the maximum rate
permitted by applicable law.  If Debtor pays to Agent or any Lender interest in
excess of the amount permitted by applicable law, such excess shall be applied
in reduction of the principal of Advances made pursuant to this Agreement or in
reduction of the principal of the Term Notes, as of the case may be, and any
remaining excess interest, after application thereof, shall be refunded to
Debtor.

     Section 7.3. Promise to Pay Fees.  Debtor promises to pay to Agent, for
the benefit of the Agent and the Lenders, as applicable, any fees specified in
Item 19 of the Schedule on the applicable due dates also specified in Item 19
of the Schedule.

     Section 7.4. Promise to Pay Costs and Expenses.  (a) Debtor agrees to pay
to Agent, on demand, all costs and expenses as provided in this Agreement, and

(vii), (viii), (ix), and (x) below, of any Lender) from time to time in
connection with this Agreement, including, without limitation, those incurred
in: (i) preparing, negotiating, amending, waiving, or granting consent with
respect to the terms of any or all of the Transaction Documents; (ii) enforcing
the Transaction Documents; (iii) performing, pursuant to Section 14.2, Debtor's
duties under the Transaction Documents upon Debtor's failure to perform them;

          (a) Payment of Principal.  Debtor authorizes Agent to apply any
     Proceeds of Collateral, including, without limitation, payments on
     Receivables, other payments from sales or leases of Inventory, and any
     funds in the Marine Payment Account, to the unpaid principal of Advances.

          (b) Payment of Interest, Fees, and Costs and Expenses.  Without

     Advance to pay for such items; or (ii) apply Proceeds of Collateral,
     including, without limitation, payments on Receivables, other payments
     from sales or leases of Inventory, and any funds in the Marine Payment
     Account, to the payment of such items.

           (c)  Notwithstanding any other provision of this Agreement, Agent, 
     in its sole discretion, shall determine the manner and amount of 
     application of payments and

                                     -25-
<PAGE>   31


     credits and Proceeds of Collateral, if any, to be made on all or any
     part of any component or components of the Indebtedness, whether
     principal, interest, fees, costs and expenses, or otherwise.

     Section 7.6. Computation of Daily Outstanding Balance.  For the purpose of
calculating the aggregate principal balance of outstanding Advances under
Section 2.1, Advances shall be deemed to be paid on the date that checks drawn
on, or other funds received from, the Marine Payment Account are applied by
Agent to Advances, and on the date any other payments on Receivables, or other
payments from sales or leases of Inventory to be so applied, have been
processed for collection by Agent; provided, however, for the purpose of
calculating interest payable by Debtor, funds from the Marine Payment Account,
payments on Receivables, other payments from sales or leases of Inventory, and
any other payments, shall be deemed to be applied to Advances the number of
days specified in Item 20 of the Schedule after the application of such funds
from the Marine Payment Account or receipt of such payments by Agent, and the
amount of interest payable will be adjusted by Agent from time to time
accordingly.  Notwithstanding any other provision of this Agreement, if any
item presented for collection by Agent is not honored, Agent may reverse any
provisional credit which has been given for the item and make appropriate
adjustments to the amount of interest and principal due.

     Section 7.7. Account Stated.  Debtor agrees that each monthly or other
statement of account mailed or delivered by Agent to Debtor pertaining to the
outstanding balance of Advances and of the Term Notes, the amount of interest
due thereon, fees, and costs and expenses shall be final, conclusive and
binding on Debtor and shall constitute an "account stated" with respect to the
matters contained therein unless, within sixty (60) calendar days from when
such statement is mailed or, if not mailed, delivered to Debtor, Debtor shall
deliver to Agent written notice of any objections which it may have as to such
statement of account, and in such event, only the items to which objection is
expressly made in such notice shall be considered to be disputed by Debtor.

     Section 7.8. Voluntary Repayments of the Term Notes.  The Term Notes may
be prepaid in whole or in part (but if in part, then in a minimum amount of
$10,000 in the aggregate or, if less, the remaining outstanding principal
balance thereof) at any time or from time to time.  All such prepayments shall
be made upon not less than one (1) Business Day's prior notice to Agent and
shall be accompanied by accrued interest on the amount prepaid to the date
fixed for prepayment.  All such prepayments shall be applied to the
installments due thereon in the inverse order of their maturities.

ARTICLE  8. PROCEDURES AFTER SCHEDULING RECEIVABLES.

     Section 8.1. Returned Merchandise.  Prior to the occurrence of any Event
of Default hereunder, Debtor shall notify Agent immediately of the return,
rejection, repossession, stoppage in transit, loss, damage, or destruction of
any Inventory having an invoice amount of more than $100,000.  After the 
occurrence of any Event of Default hereunder, Debtor shall notify Agent 
immediately of any such event, regardless of amount. Agent shall make

                                     -26-
<PAGE>   32


appropriate adjustments to the Receivables Borrowing Base and the Inventory
Borrowing Base to reflect the return of such Inventory.

     Section 8.2. Credits and Extensions.

     (a) Granting of Credits and Extensions.  Debtor may grant such Credits and
such Extensions as are ordinary in the usual course of Debtor's business
without the prior consent of Agent or the Lenders; provided, however, that any
such Extension shall not extend the time for payment beyond sixty (60) days
after the original due date as shown on the Invoice evidencing the related
Receivable, or as computed based on the information set forth on such Invoice.

     (b) Accounting for Credits and Extensions.  Debtor shall make a full
accounting of each grant of a Credit or an Extension, including a brief
description of the reasons therefor and a copy of all credit memoranda.  Such
accountings shall be in form satisfactory to Agent and shall be delivered to
Agent daily or at such other intervals as may be specified in Item 17 of the
Schedule.  All credit memoranda issued by Debtor shall be numbered and copies
of the same, when delivered to Agent, shall be in numerical order and accounted
for in the same manner as provided in Section 5.2 with respect to Invoices.

     (c) Adjustment to Receivables Borrowing Base.  The Receivables Borrowing
Base will be reduced by the amount of all Credits reflected in an accounting
required by Section 8.2(b) and by the full amount of any Receivables for which
Extensions were granted.

     Section 8.3. Returned Instruments.  In the event that any check or other
instrument received in payment of a Receivable shall be returned uncollected
for any reason, Agent shall again forward the same for collection or return the
same to Debtor.  Upon receipt of a returned check or instrument by Debtor,
Debtor shall immediately make the necessary entries on its books and records to
reinstate the Receivable as outstanding and unpaid and immediately notify Agent
of such entries.  All Receivables of an Account Debtor with respect to which
such check or instrument was received may upon Agent's notice to Debtor
(written or oral) thereupon become Ineligible Receivables.

     Section 8.4. Debit Memoranda For Receivables.  (a) Unless Agent otherwise
notifies Debtor in writing, Debtor shall deliver at least weekly to Agent,
together with the schedule of Receivables provided for in Item 17 of the
Schedule, copies of all debit memoranda issued by Debtor.

     (b) All debit memoranda issued by Debtor shall be numbered and copies of
the same, when delivered to Agent, shall be in numerical order and accounted
for in the same manner as provided in Section 5.2 with respect to Invoices.

     Section 8.5. Notes Receivable.  Debtor shall not accept any note or other
instrument (except a check or other instrument for the immediate payment of
money) with respect to any Receivable without the prior written consent of
Agent.  If Agent, in its reasonable judgment, consents to the acceptance of any
such note or instrument, the same shall be

                                     -27-
<PAGE>   33


considered as evidence of the Receivable giving rise to such note or
instrument, shall be subject to the Security Interest, and shall not constitute
payment of such Receivable, and Debtor shall forthwith endorse such note or
instrument to the order of Agent and deliver the same to Agent, together with
the Schedule listing the Receivables which it evidences.  Upon collection, the
proceeds of such note or instrument may be applied directly to unpaid Advances,
the unpaid principal balance of the Term Notes, interest, and costs and
expenses as provided in Section 7.5.

guarantor or Consolidated Subsidiary (i) any event described in Section
11.1(e), 11.1(f), 11.1(g), or 11.1(h) and, in the case of any of the foregoing

the execution of this Agreement there shall have been any materially adverse

shall, declare the obligations of the Lenders and the Agent hereunder to be
cancelled, and the principal of the Indebtedness then outstanding to be
immediately due and payable (including, without limitation, Indebtedness
outstanding under the Notes), together with all interest thereon and costs and
expenses accruing under the Transaction Documents.  Upon such declaration, any
obligations the Lenders and the Agent may have hereunder shall be immediately
cancelled, and the Indebtedness then outstanding (including, without
limitation, Indebtedness outstanding under the Notes) shall become immediately
due and payable without presentation, demand, or further notice of any kind to
Debtor.

     (b) Upon the happening of one or more Events of Default under Section

Indebtedness then outstanding (including, without limitation, Indebtedness
outstanding under the Notes) shall become immediately due and payable without

ARTICLE  12. AGENT'S RIGHTS AND REMEDIES

     Section 12.1. Generally.  Agent's rights and remedies with respect to the
Collateral, in addition to those rights granted herein and in any other
agreement between Debtor and Agent or any Lender now or hereafter in effect,
shall be those of a secured party under the Uniform Commercial Code as in
effect in the State and under any other applicable law.

     Section 12.2. Notification of Account Debtors.  Upon the occurrence of an
Event of Default or an event which with notice or lapse of time, or both, would
constitute an Event of Default, Agent may, at any time and from time to time,
notify any or all Account Debtors of the Security Interest and may direct such
Account Debtors to make all payments on Receivables directly to Agent.

     Section 12.3. Possession of Collateral.  Whenever Agent may take
possession of the Collateral, pursuant to Section 12.1, Agent may take
possession of the Collateral on Debtor's premises or may remove the Collateral,
or any part thereof, to such other places as Agent may, in its sole discretion,
determine.   If requested by Agent, Debtor shall assemble the Collateral and
deliver it to Agent at such place as may be designated by Agent.

     Section 12.4. Collection of Receivables.  Upon the occurrence of an Event
of Default or an event which with notice or lapse of time, or both, would
constitute an Event of Default, Agent may demand, collect, and sue for all
monies and Proceeds due, or to become due, on the Receivables (in either 
Debtor's or Agent's name at the latter's option) with the right to enforce, 
compromise, settle, or discharge any or all Receivables.  If Agent takes any 
action contemplated by this Section with respect to any Receivable, Debtor 
shall not exercise any right that Debtor would otherwise have had to take such
action with respect to such Receivable.

                                     -38-
<PAGE>   44

     Section 12.5. Endorsement of Checks; Debtor's Mail.  Debtor hereby
irrevocably appoints Agent the Debtor's agent with full power, in the same
manner, to the same extent, and with the same effect as if Debtor were to do
the same: to endorse Debtor's name on any Instruments or Documents pertaining
to any Collateral and, upon the occurrence of an Event of Default or an event
which with notice or lapse of time, or both, would constitute an Event of
Default, to receive and collect all mail addressed to Debtor, direct the place
of delivery of such mail to any location designated by Agent, open such mail,
remove all contents therefrom, and retain all contents thereof constituting or
relating to the Collateral.  This agency is unconditional and shall not
terminate until all of the Indebtedness is paid in full and this Agreement has
been terminated.  Agent agrees to give Debtor notice in the event it exercises
this agency, except with respect to the endorsement of Debtor's name on any
instruments or documents pertaining to any Collateral.

     Section 12.6. License To Use Patents, Trademarks, and Tradenames.  Debtor
grants to Agent a royalty-free license to use any and all patents, trademarks,
and tradenames now or hereafter owned by, or licensed to, Debtor for the
purposes of manufacturing and disposing of Inventory after the occurrence of an
Event of Default.  All Inventory shall at least meet quality standards
maintained by Debtor prior to such Event of Default.

ARTICLE 13. THE AGENT.

     Section 13.1. Appointment and Authorization.  Each Lender hereby appoints
and authorizes Agent to take such action as agent on its behalf and to exercise
such powers hereunder and under the other Transaction Documents as are
designated to Agent by the terms hereof and thereof together with such powers
as are reasonably incidental thereto.  Lenders expressly agree that Agent is
not acting as a fiduciary of Lenders in respect of the Transaction Documents,
Debtor or otherwise and nothing herein or in any of the other Transaction
Documents shall result in any duties or obligations on Agent except as
expressly set forth therein.  Subject to the other conditions of this Section
13.1, Agent may resign at any time by sending twenty (20) days prior written
notice to Debtor and Lenders.  In the event of any such resignation, the
Required Lenders may appoint a new agent, after consultation with Debtor (and,
so long as no Event of Default exists, with Debtor's consent), which shall
succeed to all the rights, powers and duties of Agent hereunder and under the
other Transaction Documents.  Any resigning Agent shall be entitled to the
benefit of all the protective provisions hereof with respect to its acts as an
agent hereunder, but no successor Agent shall in any event be liable or
responsible for any actions of its predecessor.  No such resignation shall be
effective unless and until such a successor is appointed.

     Section 13.2. Rights as a Lender.  Agent has and reserves all of the
rights, powers and duties hereunder and under the other Transaction Documents
as any Lender may have and may exercise the same as though it were not Agent.
The terms "Lender" or "Lenders" as used herein and in all of the other
Transaction Documents shall, unless the context otherwise expressly indicates,
include Agent in its individual capacity as a Lender.

     Section 13.3. Standard of Care.  Lenders acknowledge that they have
received and approved copies of the Transaction Documents and such other
information and documents 

                                     -39-
<PAGE>   45

concerning the transactions contemplated and financed hereby as they have
requested to receive and/or review.  Agent makes no representations or
warranties of any kind or character to Lenders with respect to the validity,
enforceability, genuineness, perfection, value, worth or collectibility hereof
or of the Notes or any of the other Indebtedness or of the Transaction
Documents or of the liens provided for thereby or of any other documents called
for hereby or thereby or of the Collateral.  Agent need not verify the worth or
existence of the Collateral and may rely exclusively on reports of Debtor with
respect thereto.  Neither Agent nor any director, officer, employee, agent or
representative thereof (including any security trustee therefor) shall in any
event be liable for any clerical errors or errors in judgment, inadvertence or
oversight, or for action taken or omitted to be taken by it or them hereunder
or under the other Transaction Documents or in connection herewith or therewith
except for its or their own gross negligence or willful misconduct.  Agent
shall incur no liability under or in respect of this Agreement or the other
Transaction Documents by acting upon any notice, certificate, warranty,
instruction or statement (oral or written) of anyone (including anyone in good
faith believed by it to be authorized to act on behalf of Debtor), unless it
has actual knowledge of the untruthfulness of same.  Agent may execute any of
its duties hereunder by or through employees, agents, and attorneys-in-fact and
shall not be answerable to Lenders for the default or misconduct of any such
agents or attorneys-in-fact selected with reasonable care.  Agent shall be
entitled to advice of counsel concerning all matters pertaining to the agency
hereby created and its duties hereunder, and shall incur no liability to anyone
and be fully protected in acting upon the advice of such counsel.  Agent shall
be entitled to assume that no Event of Default or event which, with notice or
lapse of time, or both, would constitute an Event of Default exists unless
notified to the contrary by a Lender.  Agent shall in all events be fully
protected in acting or failing to act in accord with the instructions of the
Required Lenders.  Upon the occurrence of an Event of Default hereunder, Agent
shall take such action with respect to the enforcement of the liens on the
Collateral and the preservation and protection thereof as it shall be directed
to take by the Required Lenders, but unless and until the Required Lenders have
given such direction Agent shall take or refrain from taking such actions as it
deems appropriate and in the best of interest of all Lenders.  Agent shall in
all cases be fully justified in failing or refusing to act hereunder unless it
shall be indemnified to its satisfaction by Lenders against any and all
liability and expense which may be incurred by Agent by reason of taking or
continuing to take any such action. Agent may treat the owner of any
Indebtedness as the holder thereof until written notice of transfer shall have
been filed with Agent signed by such owner in form satisfactory to Agent.  Each
Lender acknowledges that it has independently and without reliance on Agent or
any other Lender and based upon such information, investigations and inquiries
as it deems appropriate made its own credit analysis and decision to extend
credit to Debtor.  It shall be the responsibility of each Lender to keep itself
informed as to the creditworthiness of Debtor and Agent shall have no liability
to any Lender with respect thereto.

     Section 13.4. Costs and Expenses.  Each Lender agrees to reimburse Agent
for all costs and expenses (including, without limitation, attorneys' fees)
suffered or incurred by Agent or any security trustee in performing its duties
hereunder and under the other Transaction Documents, or in the exercise of any
right or power imposed or conferred upon Agent hereby or thereby, to the extent
that Agent is not promptly reimbursed for same by 

                                     -40-
<PAGE>   46

Debtor or out of the proceeds of the Collateral, all such costs and
expenses to be borne by Lenders ratably in accordance with their pro rata share
thereof (based on the outstanding principal amount of Indebtedness owing to
each).  If any Lender fails to reimburse Agent for such Lender's share of any
such costs and expenses, such costs and expenses shall be paid pro rata by the
remaining Lenders, but without in any manner releasing the defaulting Lender
from its liability hereunder.

     Section 13.5. Indemnity.  Lenders shall ratably indemnify and hold Agent
and its directors, officers, employees, agents and representatives (including
as such any security trustee therefor) harmless from and against any
liabilities, losses, costs and expenses suffered or incurred by it hereunder or
under the other Transaction Documents or in connection with the transactions
contemplated hereby or thereby, regardless of when asserted or arising, except
to the extent Agent is promptly reimbursed for the same by Debtor or out of the
proceeds of the Collateral and except to the extent that any event giving rise
to a claim was caused by the gross negligence or willful misconduct of Agent.
If any Lender defaults in its obligations hereunder, its share of the
obligations shall be paid pro rata by the remaining Lenders, but without in any
manner releasing the defaulting Lender from its liability hereunder.

ARTICLE 14. MISCELLANEOUS.

     Section 14.1. Perfecting the Security Interest; Protecting the Collateral.
Debtor hereby authorizes Agent to file such financing statements relating to
the Collateral without Debtor's signature thereon as Agent may deem
appropriate, and hereby appoints Agent as Debtor's attorney-in-fact with full
power (without requiring Agent) to execute any such financing statement or
statements in Debtor's name upon prior notice to Debtor and to perform all
other acts which Agent deems appropriate to perfect and continue the Security
Interest and to protect, preserve, and realize upon the Collateral.

     Section 14.2. Performance of Debtor's Duties.  Upon Debtor's failure to
perform any of its duties under the Transaction Documents, including, without
limitation, the duty to obtain insurance as specified in Section 9.11, Agent
may, but shall not be obligated to, perform any or all such duties.

     Section 14.3. Notice of Sale.  Without in any way requiring notice to be
given in the following manner, Debtor agrees that any notice by Agent of sale,
disposition, or other intended action hereunder, or in connection herewith,
whether required by the Uniform Commercial Code as in effect in the State or
otherwise, shall constitute reasonable notice to Debtor if such notice is
mailed by regular or certified mail, postage prepaid, at least ten (10) days
prior to such action, to Debtor's address or addresses specified above or to
any other address which Debtor has specified in writing to Agent as the address
to which notices hereunder shall be given to Debtor.

     Section 14.4. No Waiver by Lenders.  No course of dealing between Debtor
and Agent or any Lender and no delay or omission by Agent or any Lender in
exercising any right or remedy under the Transaction Documents or with respect
to any Indebtedness shall 


                                     -41-

<PAGE>   47

operate as a waiver thereof or of any other right or remedy, and no single or 
partial exercise thereof shall preclude any other or further exercise thereof 
or the exercise of any other right or remedy.  All rights and remedies of 
Agent and Lenders are cumulative.

     Section 14.5. Waiver by Debtor.  Neither Agent nor any Lender shall have
any obligation to take, and Debtor shall have the sole responsibility for
taking, any and all steps to preserve rights against any and all Account
Debtors and against any and all prior parties to any note, Chattel Paper,
draft, trade acceptance, or other instrument for the payment of money covered
by the Security Interest whether or not in Agent's or any Lender's possession.
Absent gross negligence or bad faith, neither Agent nor any Lender shall be
responsible to Debtor for loss or damage resulting from Agent's or such
Lender's failure to enforce any Receivables or to collect any moneys due, or to
become due, thereunder or other Proceeds constituting Collateral hereunder.
Debtor waives protest of any note, check, draft, trade acceptance, or other
instrument for the payment of money constituting Collateral at any time held by
Agent or any Lender on which Debtor is in any way liable and waives notice of
any other action taken by Agent or any Lender, including, without limitation,
notice of Agent's or any Lender's intent to accelerate the Indebtedness or any
part thereof.

     Section 14.6. Set-off.  Without limiting any other right of Agent or any
Lender, whenever Agent or any Lender has the right to declare any Indebtedness
to be immediately due and payable (whether or not it has so declared), Agent or
any such Lender, at its sole election, may set-off against the Indebtedness any
and all monies then or thereafter owed to Debtor by Agent or such Lender in any
capacity, whether or not the Indebtedness or the obligation to pay such monies
owed by Agent or such Lender is then due, and Agent or such Lender shall be
deemed to have exercised such right of set-off immediately at the time of such
election even though any charge therefor is made or entered on Agent's or such
Lender's records subsequent thereto.  Each Lender hereby agrees with each of
the other Lenders that if it should receive or obtain any payment (whether by
voluntary payment, by realization upon Collateral, by the exercise of rights of
set-off or banker's lien, by counterclaim or cross action, or by the
enforcement of any rights under this Agreement, any of the other Transaction
Documents or otherwise) in respect of the Indebtedness in a greater amount than
such Lender would have received had such payment been made to the Agent and
been distributed among the Lenders as contemplated by this Agreement, then in
that event the Lender receiving such disproportionate payment shall purchase
for cash without recourse from the other Lenders an interest in the
Indebtedness of Debtor to such Lenders in such amount as shall result in a
distribution of such payment as contemplated hereby.  In the event any payment
made to a Lender and shared with the other Lenders pursuant to the provisions
hereof is ever recovered from such Lender, the Lenders receiving a portion of
such payment hereunder shall restore the same to the payor Lender, but without
interest.

     Section 14.7. Assignments and Participations.

     (a) Assignments of Loan Commitments.  Each Lender may, from time to time
upon at least five (5) Business Days' prior written notice to Agent and Debtor,
assign to other commercial lenders all or part of its rights and obligations
under this Agreement (including, 


                                     -42-

<PAGE>   48

without limitation, the indebtedness evidenced by the Notes then owned
by such assigning Lender, together with an equivalent proportion of its
obligation to make loans and advances and participate in the credit risk on
Letters of Credit hereunder) pursuant to an Assignment Agreement in form and
substance satisfactory to Agent (each, an "Assignment Agreement"); provided,
however, that (i) each such assignment shall be of a constant, and not a
varying, percentage of the assigning Lender's rights and obligations under this
Agreement and the assignment shall cover the same percentage of such Lender's
Loan Commitments, Notes and the loans and advances evidenced thereby, and
credit risk with respect to Letters of Credit; (ii) unless the Agent otherwise
consents, the aggregate amount of the Loan Commitments, Notes and the loans and
advances evidenced thereby, and credit risk with respect to Letters of Credit
of the assigning Lender being assigned pursuant to each such assignment
(determined as of the effective date of the relevant Assignment Agreement)
shall in no event be less than $5,000,000 and shall be an integral multiple of
$1,000,000; (iii) Agent and, so long as no Event of Default then exists, Debtor
must each consent to each such assignment to a party which was not an original
signatory of this Agreement; (iv) without the consent of each Lender, Agent
will not voluntarily reduce its aggregate Loan Commitments below $5,000,000
except as part of the termination of all the Loan Commitments of the Lenders;
and (v) the assigning Lender must pay to Agent a processing and recordation fee
of $2,500 and any out-of-pocket attorneys' fees and expenses incurred by Agent
in connection with such Assignment Agreement.  Upon the execution of each
Assignment Agreement by the assigning Lender thereunder, the assignee lender
thereunder, Agent and, so long as no Event of Default then exists, Debtor, and
payment to such assigning Lender by such assignee lender of the purchase price
for the portion of the Indebtedness of Debtor being acquired by it, (i) such
assignee lender shall thereupon become a "Lender" for all purposes of this
Agreement with Loan Commitments in the amounts set forth in such Assignment
Agreement and with all the rights, powers and obligations afforded a Lender
hereunder, (ii) such assigning Lender shall have no further liability for
funding the portion of its Loan Commitments assumed by such other Lender and
(iii) the address for notices to such assignee Lender shall be as specified in
the Assignment Agreement executed by it.  Concurrently with the execution and
delivery of such Assignment Agreement, Debtor shall execute and deliver Notes
to the assignee Lender in the respective amounts of its Loan Commitments and
new Notes to the assigning Lender in the amount of its Loan Commitments after
giving effect to the reduction occasioned by such assignment, all such Notes to
constitute "Notes" for all purposes of this Agreement and the other Transaction
Documents.

     (b) Participations.  Any Lender may grant participations in its extensions
of credit hereunder to any other Lender or other lending institution (a
"Participant"), provided that (i) no Participant shall thereby acquire any
direct rights under this Agreement or any other Transaction Document, (ii) no
Lender shall agree with a Participant not to exercise any of such Lender's
rights hereunder without the consent of such Participant except for rights
which under the terms hereof may only be exercised by all Lenders and (iii) no
sale of a participation in extensions of credit shall in any manner relieve the
selling Lender of its obligations hereunder.

     Section 14.8. Successors and Assigns.  Agent, Lenders and Debtor, as used
herein, shall include the successors and permitted assigns of those parties,
except that Debtor shall 


                                     -43-
<PAGE>   49

not have the right to assign its rights hereunder or any interest herein 
without the prior written consent of Agent and Lenders.

     Section 14.9. Waivers, Modifications and Amendments.  Any provision hereof
or of any of the other Transaction Documents may be amended, modified, waived
or released and any Event of Default or event which, with notice or lapse of
time, or both, would constitute an Event of Default and its consequences may be
rescinded and annulled upon the written consent of the Required Lenders;
provided, however, that, without the consent of each Lender, no such amendment,
modification or waiver shall (i) increase the amount or extend the term of any
of Lender's Loan Commitments, (ii) reduce the amount of any principal of or
interest rate applicable to, or extend the due date of, any loans or advances
owed to such Lender, (iii) reduce the amount of any fees to which such Lender
is entitled hereunder, (iv) increase any advance rate used in computing the
Borrowing Capacity or increase any sublimit for Inventory set forth therein,
(v) release, during any one calendar year, more than $500,000 in value of the
Collateral (except in connection with a sale or other disposition permitted by
the provisions hereof or of the relevant Transaction Document), (vi) release
any guarantor of the Indebtedness, (vii) amend, modify or waive any covenant
set forth in Items 26 or 27 to the Schedule if the effect of such act would be
to loosen the requirements imposed upon Debtor pursuant to any such covenant by
more than 15% of the threshold amount then required of Debtor in order to be in
compliance with the terms thereof prior to giving effect to any such act, or
(viii) change this Section or change the definition of "Required Lenders" or
change the number of Lenders required to take any action hereunder or under any
of the other Transaction Documents.  No amendment, modification or waiver of
Agent's protective provisions shall be effective without the prior written
consent of Agent.  Anything contained herein to the contrary notwithstanding,
Agent may knowingly permit the outstanding principal amount of Advances to
exceed the loan formula set forth in part (B) of the Borrowing Capacity by up
to $250,000 at any time for up to five (5) consecutive Business Days during any
thirty (30) day period (herein, an "Overadvance"), and each Lender shall be
obligated to fund its pro rata share thereof (based on the proportion which
such Lender's Revolving Loan Commitment bears to the aggregate amount of the 
Revolving Loan Commitments) in accordance with the other terms of this 
Agreement (it being acknowledged and agreed by Debtor that Agent is not 
obligated to make any Overadvance to Debtor, any such Overadvance being at the
sole and absolute discretion of Agent in its administration of the credit 
facilities described in this Agreement).

     Section 14.10. Counterparts.  This Agreement may be executed in any number
of counterparts, and by Agent, Lenders and Debtor on separate counterparts,
each of which, when so executed and delivered, shall be an original, but all of
which shall together constitute one and the same Agreement.

     Section 14.11. Generally Accepted Accounting Principles.  Any financial
calculation to be made, all financial statements and other financial
information to be provided, and all books and records to be kept in connection
with the provisions of this Agreement, shall be in accordance with generally
accepted accounting principles consistently applied during each interval and
from interval to interval; provided, however, that in the event changes in
generally accepted accounting principles shall be mandated by the Financial
Accounting 


                                     -44-

<PAGE>   50


Standards Board or any similar accounting body of comparable standing,
or should be recommended by Debtor's certified public accountants, to the
extent such changes would affect any financial calculations to be made in
connection herewith, such changes shall be implemented in making such
calculations only from and after such date as Debtor, Agent and the Required
Lenders shall have amended this Agreement to the extent necessary to reflect
such changes in the financial and other covenants to which such calculations
relate.

     Section 14.12. Indemnification.  (a) If after receipt of any payment of
all, or any part of, the Indebtedness, Agent or any Lender is, for any reason,
compelled to surrender such payment to any person or entity because such
payment is determined to be void or voidable as a preference, an impermissible
set-off, or a diversion of trust funds, or for any other reason, the
Transaction Documents shall continue in full force and Debtor shall be liable,
and shall indemnify and hold Agent and each Lender harmless for, the amount of
such payment surrendered.  The provisions of this Section shall be and remain
effective notwithstanding any contrary action which may have been taken by
Agent or any Lender in reliance upon such payment, and any such contrary action
so taken shall be without prejudice to Agent's or any such Lender's rights
under the Transaction Documents and shall be deemed to have been conditioned
upon such payment having become final and irrevocable.  The provisions of this
Section 14.12(a) shall survive the termination of this Agreement and the
Transaction Documents.

     (b) Debtor agrees to indemnify, defend, and hold harmless Agent and
each Lender from, and against, any and all liabilities, claims, damages,
penalties, expenditures, losses, or charges, including, but not limited to, all
costs of investigation, monitoring, legal representations, remedial response,
removal, restoration, or permit acquisition, which may now, or in the future,
be undertaken, suffered, paid, awarded, assessed, or otherwise incurred by
Agent or any Lender as a result of the presence of, Release of, or threatened
Release of Hazardous Substances on, in, under, or near the property owned,
leased, or operated by Debtor or any Consolidated Subsidiary.  The liability of
Debtor under the covenants of this Section 14.12(b) is not limited by any
exculpatory provisions in this Agreement or any other documents securing the
Indebtedness and shall survive repayment of the Indebtedness or any transfer or
termination of this Agreement regardless of the means of such transfer or
termination. Debtor agrees that neither Agent nor any Lender shall be liable in
any way for the completeness or accuracy of any Environmental Report or the
information contained therein.  Debtor further agrees that neither Agent nor
any Lender has any duty to warn Debtor or any other person or entity about any
actual or potential environmental contamination or other problem that may have
become apparent, or will become apparent, to Agent or such Lender.

     (c) Debtor agrees to pay, indemnify, and hold Agent and each Lender
harmless from, and against, any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements of any kind or nature whatsoever (including, without limitation,
counsel and special counsel fees and disbursements in connection with any
litigation, investigation, hearing, or other proceeding) with respect, or in
any way related, to the existence, execution, delivery, enforcement,
performance, and administration of this Agreement and any other Transaction
Document (all of the foregoing, 


                                     -45-

<PAGE>   51

collectively, the "Indemnified Liabilities"). The agreements in this
Section 14.12(c) shall survive repayment of the Indebtedness.

     Section 14.13. Termination; Prepayment Premium.

     (a) Termination. This Agreement is, and is intended to be, a continuing
Agreement and shall remain in full force and effect for the term set forth in
Item 29 of the Schedule (the "Termination Date").  Agent may terminate this
Agreement immediately and without notice upon the occurrence of an Event of
Default.  Notwithstanding the foregoing or anything in this Agreement or
elsewhere to the contrary, the Security Interest, Agent's and each Lender's
rights and remedies under the Transaction Documents and Debtor's obligations
and liabilities under the Transaction Documents, shall survive any termination
of this Agreement and shall remain in full force and effect until all of the
Indebtedness outstanding, or contracted or committed for (whether or not
outstanding), together with interest accruing thereon, shall be finally and
irrevocably paid in full.  No Collateral shall be released or financing
statement terminated until final payment in full of the Indebtedness as
described in the preceding sentence is received in good funds.  At such time of
payment or as soon thereafter as is practicable, but in no event later than ten
(10) Business Days after such payment, Debtor, Agent, and Lenders agree to
execute a mutual general release, subject to Section 14.12 of this Agreement,
in form and substance satisfactory to the Debtor, Agent, and Lenders and their
counsel.

     (b) Prepayment Premium.  If Debtor voluntarily terminates this Agreement
with respect to Advances to be made hereunder prior to the end of the term of
this Agreement as set forth in Item 29 of the Schedule, Debtor shall also pay
to Agent for the benefit of the Lenders at the time of such termination the 
prepayment premium set forth in Item 31 of the Schedule.

     Section 14.14. Further Assurances.  From time to time, Debtor shall take
such action and execute and deliver to Agent such additional documents,
instruments, certificates, and agreements as Agent may reasonably request to
effectuate the purposes of the Transaction Documents.

     Section 14.15. Headings.  Article and Section headings used in this
Agreement are for convenience only and shall not affect the construction of
this Agreement.

     Section 14.16. Cumulative Security Interest, Etc.  The execution and
delivery of this Agreement shall in no manner impair or affect any other
security (by endorsement or otherwise) for payment or performance of the
Indebtedness, and no security taken hereafter as security for payment or
performance of the Indebtedness shall impair in any manner or affect this
Agreement, or the security interest granted hereby, all such present and future
additional security to be considered as cumulative security.

     Section 14.17. Secured Party's Duties.  Without limiting any other
provision of this Agreement: (a) the powers conferred on Agent hereunder are
solely to protect its interests and the interests of Lenders and shall not
impose any duty on Agent or Lenders to exercise 


                                     -46-

<PAGE>   52

any such powers; and (b) except as may be required by applicable law,
Agent shall not have any duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against any parties or any other rights
pertaining to any Collateral.

     Section 14.18. Notices Generally.  Except as otherwise provided herein,
all notices and other communications hereunder shall be made by telegram,
telex, electronic transmitter, overnight air courier, or certified or
registered mail, return receipt requested, and shall be deemed to be received
by the party to whom sent one Business Day after sending, if sent by telegram,
telex, electronic transmitter, or overnight air courier, and three Business
Days after mailing, if sent by certified or registered mail; provided that any
notice of a request for an Advance or of an interest rate option to be selected
hereunder shall be effective only upon receipt.  All such notices and other
communications to a party hereto shall be addressed to such party at the
address set forth on the cover page hereof, if to Debtor or Agent, or to such
party at the address set forth on the signature page hereof, if to any Lender,
or to such other address as such party may designate for itself in a notice to
the other party given in accordance with this Section 14.18 and, with respect
to any notice which Agent is required to give Debtor hereunder, with a copy to
Henry Underwood, Esq., Defrees & Fiske, Suite 1100, 200 South Michigan Avenue,
Chicago, Illinois  60604.

     Section 14.19. Severability.  The provisions of this Agreement are
independent of, and separable from, each other, and no such provision shall be
affected or rendered invalid or unenforceable by virtue of the fact that for
any reason any other such provision may be invalid or unenforceable in whole or
in part.  If any provision of this Agreement is prohibited or unenforceable in
any jurisdiction, such provision shall be ineffective in such jurisdiction 
only to the extent of such prohibition or unenforceability, and such 
prohibition or unenforceability shall not invalidate the balance of such 
provision to the extent it is not prohibited or unenforceable nor render
prohibited or unenforceable such provision in any other jurisdiction.

     Section 14.20. Inconsistent Provisions.  The terms of this Agreement
(including the Schedule which is a part hereof) and the other Transaction
Documents shall be cumulative except to the extent that they are specifically
inconsistent with each other, in which case the terms of this Agreement shall
prevail.

     Section 14.21. Entire Agreement.  This Agreement and the other Transaction
Documents constitute the entire agreement and understanding between the parties
hereto with respect to the transactions contemplated hereby and supersede all
prior negotiations, understandings, and agreements between such parties with
respect to such transactions, including, without limitation, those expressed in
any commitment letter delivered by any Lender to Debtor.

     Section 14.22. Applicable Law.  THIS AGREEMENT, AND THE TRANSACTIONS
EVIDENCED HEREBY, SHALL BE GOVERNED BY, AND CONSTRUED UNDER, THE INTERNAL LAWS
OF THE STATE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW, AS THE SAME MAY
FROM TIME TO TIME BE IN EFFECT, INCLUDING, WITHOUT LIMITATION, THE UNIFORM
COMMERCIAL CODES IN EFFECT IN THE STATE.

18.  Interest Rate (Section 7.2)

          (a) Interest Rate Options.  Subject to all of the terms and
     conditions of this Item 18, portions of the Advances and the Indebtedness
     evidenced by the Term Notes (all of the Advances bearing interest at the
     same rate for the same period of time, and all of the Indebtedness
     evidenced by the Term Notes bearing interest at the same rate for the same
     period of time, being hereinafter referred to as a "Portion") may, at the
     option of Debtor, bear interest with reference to the Prime Rate (a "Prime
     Rate Portion") or with reference to the Adjusted LIBOR ("LIBOR Portions"),
     and Portions of the relevant Indebtedness may be converted from time to
     time from one basis to 





                                     -7-

<PAGE>   62

     another.  All of the Advances which are not part of a LIBOR Portion shall
     constitute a single Prime Rate Portion, and all of the Indebtedness 
     evidenced by the Term Notes which is not part of LIBOR Portion shall 
     constitute a single Prime Rate Portion.  All of the Advances which bear 
     interest with reference to a particular Adjusted LIBOR for a particular 
     Interest Period shall constitute a single LIBOR Portion, and all of the 
     Indebtedness evidenced by the Term Notes which bear interest with 
     reference to a particular Adjusted LIBOR for a particular Interest
     Period shall constitute a single LIBOR Portion.  There shall not be more
     than three (3) LIBOR Portions outstanding at any one time.  Each Lender
     shall have a ratable interest in each Portion based on its percentage of
     the relevant Advances or Term Loans held by it.  Anything contained herein
     to the contrary notwithstanding, the obligation of Lenders to create,
     continue or effect by conversion any LIBOR Portion shall be conditioned
     upon the fact that at the time no Event of Default or event which with
     notice or lapse of time, or both, would constitute an Event of Default
     shall have occurred and be continuing.  Debtor hereby promises to pay
     interest on each Portion at the rates and times specified below.

          (b) Prime Rate Portion.  Each Prime Rate Portion of the relevant
     Indebtedness shall bear interest at the  rate per annum equal to the Prime
     Rate as in effect from time to time.  All Advances and Indebtedness
     evidenced by the Term Notes shall initially constitute part of a Prime
     Rate Portion, except to the extent Debtor has otherwise timely selected a
     LIBOR Portion in accordance with the terms of this Item 18.

          (c) LIBOR Portions.  Each LIBOR Portion of the relevant Indebtedness
     shall bear interest, for each Interest Period selected therefor, at a rate
     per annum determined by adding 2% to the Adjusted LIBOR for such Interest
     Period.  Effective at the end of such Interest Period such LIBOR Portion
     shall automatically be converted into and added to the applicable Prime
     Rate Portion unless such LIBOR Portion is continued or converted into
     another LIBOR Portion in accordance with the terms hereof.  Debtor shall
     notify Agent in writing (including as such any notice sent by telecopy),
     which notice shall promptly thereafter be furnished by Agent to Lenders,
     in the form attached hereto as Exhibit D on or before 11:00 a.m. (Chicago
     time) on the third Business Day preceding the end of an Interest Period
     applicable to a LIBOR Portion whether such LIBOR Portion is to continue as
     a LIBOR Portion, in which event Debtor shall notify Agent of the new
     Interest Period selected therefor, and in the event Debtor shall fail to
     so notify Agent, such LIBOR Portion shall automatically be converted into
     and added to the applicable Prime Rate Portion as of and on the last day
     of such Interest Period.  Each LIBOR Portion of Advances shall be in an
     amount equal to $1,000,000 or such greater amount which is an integral
     multiple of $100,000, and each LIBOR Portion of Indebtedness evidenced by
     the Term Notes shall be in an amount equal to $100,000 or such greater
     amount which is an integral multiple of $100,000.

          (d) Notice of Rate Selection.  Debtor shall notify Agent in writing
     (including as such any notice sent by telecopy), which notice shall
     promptly thereafter be furnished by Agent to Lenders, in the form attached
     hereto as Exhibit D by 11:00 

                                     -8-

     a.m. (Chicago time) at least three (3) Business Days prior to the date
     upon which Debtor requests that any LIBOR Portion be created or that any
     part of the relevant Prime Rate Portion be converted into a LIBOR Portion
     (each such notice to specify in each instance the amount thereof and the
     Interest Period selected therefor). If any request is made to convert a
     LIBOR Portion into another type of Portion available hereunder, such
     conversion shall only be made so as to become effective as of the last day
     of the Interest Period applicable thereto.  All requests for the creation,
     continuance and conversion of LIBOR Portions under this Agreement shall be
     irrevocable.  Such requests shall be written (including as such any notice
     sent by telecopy) in the form attached hereto as Exhibit D and Agent is
     hereby authorized to honor any request for the creation, continuance or
     conversion of any LIBOR Portion received by it from any person Agent in
     good faith believes to be an authorized representative of Debtor without
     the need of independent investigation.

          (e) Change of Law.  Notwithstanding any other provision of this
     Agreement, if at any time Agent shall determine in good faith that any
     change in applicable laws, treaties or regulations or in the
     interpretation thereof makes it unlawful or impracticable for any Lender
     to create or continue to maintain any LIBOR Portion, Agent shall promptly
     so notify  Debtor and each Lender and the obligation of any Lender to
     create, continue or maintain any such LIBOR Portion under this Agreement
     shall terminate until it is no longer unlawful or impracticable for any
     Lender to create, continue or maintain such LIBOR Portion.  On demand,
     Debtor shall, if the continued maintenance of any such LIBOR Portion is
     unlawful or impracticable, thereupon prepay the outstanding principal
     amount of the affected LIBOR Portion, together with all interest accrued
     thereon and all other amounts payable to Lenders with respect thereto
     under this Agreement; provided, however, that Debtor may elect to convert
     the principal amount of the affected LIBOR Portion into the relevant Prime
     Rate Portion available hereunder, subject to the terms and conditions of
     this Agreement together with the payment of any funding indemnity required
     by clause (h) hereof.

          (f) Unavailability of Deposits; Inability to Ascertain Adjusted
     LIBOR.  Notwithstanding any other provision of this Agreement, if, prior
     to the commencement of any Interest Period, Agent shall determine in good
     faith that deposits in the amount of any LIBOR Portion scheduled to be
     outstanding during such Interest Period are not readily available to
     Lenders in the London interbank market or, by reason of circumstances
     affecting the relevant market, adequate and reasonable means do not exist
     for ascertaining Adjusted LIBOR, then Agent shall promptly give notice
     thereof to Debtor and each Lender and the obligation of each Lender to
     create, continue or effect by conversion any such LIBOR Portion in such
     amount and for such Interest Period shall terminate until deposits in such
     amount and for the Interest Period selected by Debtor shall again be
     readily available in the London interbank market and adequate and
     reasonable means exist for ascertaining Adjusted LIBOR.

          (g) Taxes and Increased Costs.  With respect to any LIBOR Portion, if
     any Lender shall determine in good faith that any change in any applicable
     law, treaty, 

                                     -9-

     regulation or guideline (including, without limitation, Regulation D of
     the Board of Governors of the Federal Reserve System) or any new law,
     treaty, regulation or guideline, or any interpretation of any of the
     foregoing by any governmental authority charged with the administration
     thereof or any central bank or other fiscal, monetary or other authority
     having jurisdiction over such Lender or its lending branch (or any
     affiliates of such Lender providing the source of funding for such LIBOR
     Portion) or the LIBOR Portions contemplated by this Agreement (whether or
     not having the force of law but which such Lender reasonably determines
     are applicable to the relevant LIBOR Portion), shall:

               (i) impose, increase, or deem applicable any reserve, special
          deposit or similar requirement against assets held by, or deposits in
          or for the account of, or loans by, or any other acquisition of funds
          or disbursements by, such Lender which is not in any instance already
          accounted for in computing the interest rate applicable to such LIBOR
          Portion;

               (ii) subject such Lender or any LIBOR Portion to any tax
          (including, without limitation, any United States interest
          equalization tax or similar tax however named applicable to the
          acquisition or holding of debt obligations and any interest or
          penalties with respect thereto), duty, charge, stamp tax, fee,
          deduction or withholding in respect of this Agreement or any LIBOR
          Portion, except such taxes as may be measured by the overall net
          income or gross receipts of such Lender or its lending branches and
          imposed by the jurisdiction, or any political subdivision or taxing
          authority thereof, in which such Lender's principal executive office
          or its lending branch is located;

               (iii) change the basis of taxation of payments of principal and
          interest due from Debtor to such Lender hereunder to the extent it
          evidences any LIBOR Portion (other than by a change in taxation of
          the overall net income or gross receipts of such Lender); or

               (iv) impose on such Lender any penalty with respect to the
          foregoing or any other condition regarding this Agreement, any LIBOR
          Portion, or its disbursement, or this Agreement to the extent it
          evidences any LIBOR Portion;

     and such Lender shall determine in good faith that the result of any of
     the foregoing is to increase the cost (whether by incurring a cost or
     adding to a cost) to such Lender of creating or maintaining any LIBOR
     Portion hereunder or to reduce the amount of principal or interest
     received or receivable by such Lender (without benefit of, or credit for,
     any prorations, exemption, credits or other offsets available under any
     such laws, treaties, regulations, guidelines or interpretations thereof),
     then Debtor shall pay on demand to such Lender from time to time as
     specified by such Lender such additional amounts as such Lender shall
     reasonably determine are sufficient to compensate and indemnify it for
     such increased cost or reduced amount.  If any Lender makes such a claim
     for compensation, it shall provide to Debtor (with a copy thereof to
     Agent) a certificate setting forth the computation of the increased cost
     or 

                                     -10-
<PAGE>   65

     reduced amount as a result of any event mentioned herein in
     reasonable detail and such certificate shall be conclusive if reasonably
     determined.

          (h) Funding Indemnity.  In the event any Lender shall incur any loss,
     cost or expense (including, without limitation, any loss (including loss
     of profit), cost or expense incurred by reason of the liquidation or
     reemployment of deposits or other funds acquired or contracted to be
     acquired by such Lender to fund or maintain any LIBOR Portion or the
     relending or reinvesting of such deposits or other funds or amounts paid
     or prepaid to such Lender) as a result of:

               (i) any payment of a LIBOR Portion on a date other than the last
          day of the then applicable Interest Period for any reason, whether
          before or after default, and whether or not such payment is required
          by any provisions of this Agreement; or

               (ii) any failure by Debtor to create, borrow, continue or effect
          by conversion a LIBOR Portion on the date specified in a notice given
          pursuant to this Agreement;

     then upon the demand of such Lender, Debtor shall pay to such Lender such
     amount as will reimburse such Lender for such loss, cost or expense.  If
     any Lender requests such a reimbursement, it shall provide to Debtor (with
     a copy thereof to Agent) a certificate setting forth the computation of
     the loss, cost or expense giving rise to the request for reimbursement in
     reasonable detail and such certificate shall be conclusive if reasonably
     determined.

          (i) Manner of Funding.  Each Lender may, at its option, elect to
     make, fund or maintain Portions hereunder at such of its branches or
     offices as such Lender may from time to time elect.  Notwithstanding any
     provision of this Agreement to the contrary, each Lender shall be entitled
     to fund and maintain its funding of all or any part of the Advances and
     Term Loans in any manner it sees fit, it being understood, however, that
     for the purposes of this Agreement (including, without limitation, clauses
     (g) and (h) of this Item 18) all determinations hereunder shall be made as
     if such Lender had actually funded and maintained each LIBOR Portion
     during each Interest Period applicable thereto through the purchase of
     deposits in the relevant market in the amount of such LIBOR Portion,
     having a maturity corresponding to such Interest Period, and bearing an
     interest rate equal to the LIBOR for such Interest Period.

          (j) Prepayments of Portions.  Subject to the terms and conditions of
     the Agreement, Debtor may prepay Portions in whole or in part at any time
     provided that (i) any prepayment of a LIBOR Portion on a day other than
     the last day of its Interest Period shall be accompanied by any amount due
     such Lender under clause (h) hereof and any prepayment premium required by
     Section 14.13(b) hereof and (ii) after giving effect to any partial 
     prepayment of a LIBOR Portion the minimum amount required for a LIBOR 
     Portion pursuant to clause (c) hereof remains outstanding.

          (k) Definitions.  For purposes of this Item 18, the following terms
     shall have the following meanings:

          "Adjusted LIBOR" means a rate per annum determined by Agent in
     accordance with the following formula:

          Adjusted LIBOR =       LIBOR
                          -----------------------
                          100%-Reserve Percentage


     "Reserve Percentage" means, for the purpose of computing Adjusted LIBOR,
     the maximum rate of all reserve requirements (including, without
     limitation, any marginal, emergency, supplemental or other special
     reserves) imposed by the Board of Governors of the Federal Reserve System
     (or any successor) under Regulation D on Eurocurrency liabilities (as such
     term is defined in Regulation D) for the applicable Interest Period as of
     the first day of such Interest Period, but subject to any amendments to
     such reserve requirement by such Board or its successor, and taking into
     account any transitional adjustments thereto becoming effective during
     such Interest Period.  For purposes of this definition, LIBOR Portions
     shall be deemed to be Eurocurrency liabilities as defined in Regulation D
     without benefit of or credit for prorations, exemptions or offsets under
     Regulation D.  "LIBOR" means, for each Interest Period, the rate of
     interest as determined by Agent to be the rate per annum equal to the
     London Interbank Offered Rate as shown on the Dow Jones & Company's
     Telerate Screen at approximately 11:00 a.m. (London, England time) two (2)
     Business Days before the beginning of such Interest Period for a period
     equal to such Interest Period and in an amount equal or comparable to the
     applicable LIBOR Portion scheduled to be outstanding from Agent during
     such Interest Period.

          "Interest Period" means, with respect to any LIBOR Portion, the
     period commencing on, as the case may be, the creation, continuation or
     conversion date with respect to such LIBOR Portion and ending one (1), two
     (2), three (3), six (6) or twelve (12) months thereafter as selected by
     Debtor in its notice as provided herein; provided that all of the
     foregoing provisions relating to Interest Periods are subject to the
     following: (i) if any Interest Period would otherwise end on a day which
     is not a Business Day, that Interest Period shall be extended to the next
     succeeding Business Day, unless the result of such extension would be to
     carry such Interest Period into another calendar month in which event such
     Interest Period shall end on the immediately preceding Business Day; (ii)
     no Interest Period may extend beyond the last day of the term of this
     Agreement as provided for in Section 14.13(a) of the Agreement; (iii) the
     interest rate to be applicable to each LIBOR Portion for each Interest
     Period shall apply from and including the first day of such Interest
     Period to but excluding the last day thereof; and (iv) no Interest Period
     may be selected if after giving effect thereto Debtor will be unable to 
     make a principal payment scheduled to be made during such Interest Period
     without paying part of a LIBOR Portion on a date other than the last day 
     of the Interest Period applicable thereto.  For purposes of determining 
     an Interest Period, a month means a period starting on one day in a 
     calendar month and ending on a numerically corresponding day in the next 
     calendar 

                                     -12-
<PAGE>   67


     month, provided, however, if an Interest Period begins on the last day
     of a month or if there is no numerically corresponding day in the month in
     which an Interest Period is to end, then such Interest Period shall end on
     the last Business Day of such month."
