PART I

ITEM 1 - BUSINESS

BHA Group Holdings, Inc. (together with its domestic and international
subsidiaries, the "Company" or "BHA") is a global filtration company. Its
principal business is the design, manufacture and sale of replacement parts and
the performance of rehabilitation conversion services for the types of
industrial air pollution control ("APC") equipment known as "baghouses",
"cartridge collectors" and "electrostatic precipitators". This equipment is used
to eliminate particulate from the air by passing particulate laden gases through
fabric filters or filter bags, in the case of baghouses, pleated media filter
elements, in the case of cartridge collectors and between electrically charged
collector plates, in the case of electrostatic precipitators. The Company's
business also includes the maintenance, conversion and rebuilding of this
equipment through a network of employees and independent contractors. The
Company's products and services are marketed throughout North America, South
America, Europe, the Near East, the Pacific Rim and China. While definitive
industry statistics are not available, based upon Dun & Bradstreet reports and
other financial information available to it, the Company believes it is a leader
in worldwide sales of air pollution control replacement parts and services.

The Company has also established BHA Technologies, Inc. ("BHA Technologies") as
a wholly-owned subsidiary that supplies expanded polytetrafluoroethylene
("ePTFE") membrane products for use in its APC product lines. Through BHA
Technologies, the Company plans to supply ePTFE membrane products to a new base
of customers for use outside of air pollution control.

DOMESTIC BUSINESS AND CORPORATE STRUCTURE

The following outlines a chronology relating to the establishment of the
Company's various domestic business units. The Company's international business
units are described below in the section entitled "International Business."

The Company was organized as an unincorporated division of Standard Havens, Inc.
("Standard Havens") in 1975 and was incorporated in Delaware as a wholly-owned
subsidiary of Standard Havens in 1986. The Company became publicly-owned when it
completed its


                                      -2-




<PAGE>


initial public offering of common stock in November 1986. Net proceeds from this
public offering amounted to approximately $3.6 million, which was applied to
outstanding bank debt. The Company completed a second public offering of common
stock in February 1989. Net proceeds from that public offering (approximately
$8.3 million) were used for working capital purposes and to finance several
acquisitions.

In April 1989, the Company formed PrecipTech, Inc. ("PrecipTech"), a Delaware
corporation, as a wholly-owned subsidiary. PrecipTech, which had previously been
a division of BHA, was formed for the purpose of conducting and expanding the
Company's business as it relates to replacement parts, accessories and services
for electrostatic precipitators.

During 1989, BHA and PrecipTech completed several acquisitions in efforts to
expand their product lines and services. In June 1989, BHA acquired the business
of developing and manufacturing acoustic horns for use in both baghouses and
electrostatic precipitators from Saracco Acoustic Sciences Corporation. Also in
1989, PrecipTech completed three acquisitions of privately held companies or
their operating assets. Such acquisitions included ESP Specialties, Inc., a
company that manufactured and sold replacement parts for electrostatic
precipitators; Kinetic Controls, Inc., a company that manufactured and sold
automatic voltage controllers for electrostatic precipitators; and Midwest Power
Corporation, a company that manufactured and sold replacement parts and
accessories and provided services for electrostatic precipitators.

During 1994, the Company established BHA Technologies as a Delaware Corporation.
This wholly-owned subsidiary was formed for the purpose of developing ePTFE
membranes. BHA Technologies successfully developed its own ePTFE membrane, which
it manufactures and markets for various applications both within and outside the
Company's traditional air pollution control equipment markets. In the air
pollution control market, ePTFE membrane is laminated using a thermal process to
a fabric substrate, which is then converted into a replacement filter and
marketed under the trade name BHA-TEX(R). The benefits of this product line to
the customer include improved collection efficiency, increased throughput and
lower operating costs. The ePTFE membranes are widely used outside of air
pollution control applications. These applications include, but are not limited
to, wet filtration, industrial, electrical insulation, medical and apparel. Some
of the products and processes in these applications are currently under patent
protection. In addition to supplying the Company's air pollution control
businesses with ePTFE membranes for use on filter elements, BHA Technologies
will evaluate the market niches and product opportunities available to pursue
and develop custom products and services to meet the needs of this new base of
customers.

In November 1996, the Board of Directors approved certain changes to the
Company's corporate structure. The Board determined that servicing the domestic
APC customers of its corporate business through one company, instead of through
various subsidiaries, would yield the greatest sales, marketing and operational
efficiencies. To achieve this objective, three wholly-owned subsidiaries of the
Company that were involved in various air pollution control businesses were
merged into PrecipTech to form one company. On February 18, 1997, the
shareholders of the Company approved an amendment to the Certificate of
Incorporation of the Company to change PrecipTech's name to BHA Group, Inc. and
the Company's name to BHA Group Holdings, Inc.

FACTORS AFFECTING EARNINGS AND STOCK PRICE

COMPETITION - Based upon Dun & Bradstreet reports and other publicly available
financial information, the Company believes that it is a global leader in the
APC equipment aftermarket. A number of regional offices have been established in
Asia and Latin America. As a result of this movement into the international
market, the Company is facing increased competition from competitors in those
specific markets, as well as existing competitors from the U.S. and Europe.
Several of the Company's competitors are, or are part of, large integrated
companies, which have much greater resources than the Company. The competition
also includes several dozen small to mid-size filter bag manufacturers that
compete in local and regional geographic markets. Generally, original equipment
manufacturers in the U.S. have not effectively competed in the aftermarket for
baghouses, but have been a significant factor in the aftermarket for
electrostatic precipitators.

The domestic utility market for electrostatic precipitators has been
competitive, as this industry has been restructuring in response to
deregulation. Over the last several years, competition has had a negative impact
on the profitability of orders executed within this industry group. This overall
slowdown has increased competition for industrial replacement parts and
services. The Company's domestic electrostatic precipitator replacement parts
and services ("ESP") business has become increasingly volatile in terms of
volume and profitability. Revenues of the ESP business declined from $35 million
in fiscal 1994 to $21 million in fiscal 1997 before rebounding to $26 million in
fiscal 1998 and $37 million in fiscal 1999. Recent business has been bolstered
by several large rebuilds. Competition remains intense in the ESP business based
both upon price and service. During the fiscal year ended September 30, 1999
("fiscal 1999"), the risks of the ESP business were highlighted in the Company's
second quarter when BHA announced a $2.4 million charge for cost overruns on a
large fixed-price rebuild project for a domestic electric utility contract. In
contrast, during the fourth quarter of the fiscal year, BHA successfully
executed several profitable ESP projects including two which were emergency
rebuilds following industrial explosions. The Company expects the ESP business
to continue to be volatile and believes that a downturn could have a material
adverse effect on its business. Outside of the U.S., it is important to note
that electrostatic precipitators are currently more prevalent than baghouses for
use in air pollution control systems. The Company continues to position itself
for additional growth in the international marketplace.

EXPORT SALES - The Company's domestic APC business generates significant
revenues through the sale of products and services in international markets,
primarily Asia, the Pacific Rim and Latin America. During 1997, shortly after
BHA established a sales and technical support infrastructure in Asia, the region
was hit with an economic crisis. Although this market has been slow to recover,
the Company has lowered its cost structure such that management believes current
sales volume of $5 million to $6 million represents a break-even point for the
Asia region. The markets of Latin America provided the Company with solid growth
through most of the 1990's, however, in fiscal 1999, the Asian economic crisis
spread to Latin America, resulting in a sales decline of approximately $3
million. Most of the decline was in the ESP


                                      -6-




<PAGE>


business, and thus, the Company re-deployed its resources to support the growth
of its ESP sales in the U.S. Latin America and Asia are key markets for the
Company and the ability of BHA to meet its ongoing financial targets will
depend, in part, on the economic recovery in these regions. Any prolonged delay
in the recovery of these markets for APC products and services could result in a
change in the Company's strategy and its long-term growth targets.

EUROPE - The profitability of BHA's European operations have declined in each of
the past two years and this business segment incurred significant losses in
fiscal 1999. With the consolidation of the Company's European fabric filter
manufacturing into one facility during the past year, the Company has
significantly reduced its manufacturing overhead costs. However, in order to
achieve a reasonable return on its European investment, the Company will need to
significantly increase its revenues by increasing its market share in this
region.

BHA TECHNOLOGIES - Through BHA Technologies, the Company has established a
business to supply PTFE membrane products for use in applications outside of air
pollution control. BHA Technologies remains in a startup phase in which its
investment in research and development are not currently matched by an ongoing
revenue stream. During fiscal 1999, BHA Technologies invested in marketing,
product development, technology, and the sales infrastructure necessary to meet
the anticipated demands of these new potential markets. As a result of these
efforts, BHA Technologies has developed several lines of products that are being
introduced to the marketplace.

The original business plan for expanding BHA Technologies business to include
products for non-APC applications (such as apparel, allergy and clean room
products) was to develop and manufacture expanded PTFE membrane films which,
depending on the customer application, would be laminated to a fabric. A
significant investment in equipment and technology was made relating to the
adhesive lamination process. BHA Technologies incurred $1.4 million of expense
in fiscal 1999 in its efforts to commercialize the lamination equipment with the
goal of being able to cost-effectively produce laminate product. The current
target customer base for laminated product and the challenges associated with
the lamination process have led management to conclude that using third party
laminators will be a more cost-effective method for approaching the market for
these products. As a result of this conclusion, the Company recognized a $1.7
million restructuring charge in the fourth quarter of fiscal 1999 to write such
equipment down to its estimated net realizable value. BHA Technologies will
continue its efforts relating to the development and sale of high quality
expanded PTFE membrane films for sale to customers in applications outside of
air pollution control.

For the fiscal year ending September 30, 2000 ("fiscal 2000"), BHA Technologies
is targeting a significantly lower loss, as it anticipates that revenue from
non-APC products will partially offset its ongoing investments in marketing and
product development. Additionally, BHA Technologies has reduced its cost
structure as a result of the discontinuation of in-house adhesive lamination
efforts.

Factors affecting BHA Technologies' ability to achieve its fiscal 2000 sales and
earnings targets include equipment delivery and start-up, product development
issues, customer order timelines, and production schedules. Increased
competition could also impact the fiscal 2000 plan. Although the Company
believes that it has the resources and programs in place to meet its fiscal 2000
targets, failure to do so could have a material adverse impact on the fiscal
2000 operating results of the Company, as well as on the carrying value of the
Company's investment in the property, plant, and equipment of BHA Technologies.

PRODUCTS AND SERVICES

The Company believes it has the broadest product line in the air pollution
control equipment aftermarket. This, combined with its proprietary telemarketing
system, enables it to respond promptly to customer requests, thus providing it
with a competitive advantage.

The Company manufactures and sells a wide variety of filter bags, replacement
parts and accessories for the industrial air pollution control equipment
aftermarket. Filter bags are manufactured by the Company from fabric purchased
in bulk from fabric manufacturers. The Company manufactures industry standard
bags, as well as bags for customer specific applications. Most filter bags are
produced from fiberglass, polyester, aramid, acrylic, and polypropylene fabrics.
A market shift towards higher efficiency filtration has led to increased usage
of filters that have ePTFE membrane applied to the fabric and other more
specialized materials. The Company's wholly-owned subsidiary, BHA Technologies,
manufactures the expanded PTFE membrane (BHA-TEX(R)) used on its filter bags and
elements. The Company is one of the few filter bag suppliers that manufactures
its own PTFE membrane (see "Business"), which it believes provides it a
competitive advantage as it is able to control availability, raw material costs,
quality and product development. Baghouse replacement parts include support
cages for the filter bags, clamps, spring tensioning systems, continuous
particulate monitoring systems and gaskets. Electrostatic precipitator
replacement parts include collecting plates, wires, discharge electrodes,
transformer/rectifiers, rappers and electronic controls.

In addition to standard replacement parts, the Company continues to aggressively
introduce new products and accessories that enhance the performance of a dust
collection system. These new products include continued enhancements to the
Company's electrical products for both baghouses and precipitators and the
introduction of pleated media filter elements and evaporative gas cooling
product lines. Internal product development continues to be supplemented with
strategic acquisitions such as the Drayton Corporation's sound-off acoustic
cleaner product line acquired in January 1999. By combining the Drayton horn
line with the Company's other acoustic products, BHA now has the most
comprehensive line of acoustic horns in the industry.

Product profitability varies considerably over different product groups, with
standard products typically providing a lower profit margin than replacement
parts and accessories.

The Company's business also includes the maintenance, conversion and rebuilding
of industrial air pollution control equipment through a network of independent
contractors and its own service crews. A comprehensive safety program enables
both the Company and customer to control costs from a risk management
perspective. Conversion and rebuilding services involve retrofitting a partial
or entire baghouse or electrostatic precipitator to restore it to original
operating parameters or improve overall performance. BHA is capable of supplying
a variety of other services specifically fitted to its customers' requirements,
including preventive maintenance, system/equipment analysis, inspections,
supervision of customer personnel and training. Information gathered during
preventive maintenance, analysis and inspections is stored in the Company's
database for future reference, and thus is a valuable source of important
customer information. In addition, knowledge gained in solving one customer's
problems is stored in the Company's database and made available on-line


                                      -8-




<PAGE>


to the Company's salespeople to enable them to respond promptly to similar
problems encountered by other customers. BHA believes it is one of the world
leaders in providing these services.

CUSTOMER BASE

The Company's APC customer base is diverse both industrially and geographically,
and includes customers in virtually all sectors of the industrial economy.
International markets include Canada, Europe, Latin America, the Near East, the
Pacific Rim and China. The Company's products and services are used in major
industrial environments such as cement kilns, asphalt plants, steel and iron
foundries, aluminum and copper smelters, rock and gypsum dryers, chemical
plants, grain and food processing plants, refuse to energy plants, waste and
hazardous waste incinerators and electric utilities, as well as many other
areas. In recent years, there has been an emergence of multinational companies
expanding their worldwide presence in BHA's traditional target industries.
Management believes that this trend could have a positive impact on its
international sales.

The vast majority of the Company's baghouse sales represent small transactions
with numerous customers. Precipitator replacement parts sales frequently
accompany conversion or rebuild services. No customer accounted for more than
10% of the Company's annual sales during any of its last three fiscal years. The
Company does not believe that it is dependent upon any single customer or group
of customers and has no unusual geographical or industry concentrations of
business or credit risk.

SALES AND MARKETING

One of the Company's principal competitive APC advantages is its proprietary
telesales system, the core of which is a computer database containing detailed
information on over 120,000 pieces of pollution control equipment (baghouses and
electrostatic precipitators) at over 55,000 accounts. Because of the large
number of different original equipment manufacturers and varying maintenance
procedures, many pieces of customer equipment have unique features. Included in
the Company's database is information on the location of the equipment; a phone
contact for the individuals responsible for maintaining the equipment; the type
of equipment (by manufacturer, design and unique attributes); when it was
installed; what fabric, size and design filter bags are used; when the bags were
last serviced; additional accessories that were installed; application and
temperature requirements; as well as other detailed pieces of useful information
about the equipment and the customer. This information has been gathered since
the Company was established in 1975, and is continually updated following
customer calls, site inspections and maintenance jobs.

The ongoing population of the customer database is an important part of the
Company's sales strategy. In recent years, a substantial portion of the growth
in the customer database relates to the international marketplace and segments
of the U.S. market where the Company's newer fine filtration products have
application.

The Company keeps information in a central computer database that is accessed
on-line by its telesales representatives. The computer tracks customer calls and
pending orders, which helps make efficient use of the representative's time.
Each day, a list of the most important customer calls is provided to the
representative. This list includes contracts and orders in negotiation, as


                                      -9-




<PAGE>


well as reminders for calls to customers that have not been serviced for some
time. Once an order is taken, the information is routed to the operations area
that uses the computer to generate invoices and contracts. Invoice and technical
data about the filter bags, cages, precipitator replacement parts and
accessories is sent via computer connection to the Company's manufacturing
facilities. There the bags are sewn, the support cages and precipitator
replacement parts are manufactured, and the accessories are consolidated for
shipment. The order is packaged and sent to the customer according to a priority
schedule.

Each telesales representative is furnished with data to evaluate their
performance and enable them to focus on high opportunity sales calls. Historical
sales data is made available to each telesales representative showing (i)
performance by the month and year toward targeted goals (broken down by product
category) sales volume and profit margin, (ii) the sales history for each
customer, as well as the sales potential for such customer, and (iii) a summary
of each contact with each customer and its results, including notes of any
useful information for further contacts. The Company believes that the system
provides effective feedback to telesales personnel to meet their sales goals.

In addition to its use on a customer-by-customer basis, the Company's telesales
system and database is used to develop industry statistics and analyze market
trends. Information is also extracted for marketing and advertising campaigns
and new product evaluations.

GOVERNMENT REGULATION AND INITIATIVES

The Company is not subject to direct environmental protection regulation with
respect to the manufacture or sale of its products other than regulations
applicable to manufacturers generally. The Company's customers are required to
meet national primary and secondary ambient air quality standards for specific
pollutants, including particulate matter, which have been promulgated under the
Clean Air Act, as amended (the "Act"). Title V, the cornerstone of the Act,
establishes a national operating permit program. Title V requires appropriate
and sufficient record keeping, monitoring and reporting requirements to assure
compliance with the standards established by the permitting authorities. The
states have primary responsibility for implementing these standards, and in some
cases, have adopted standards which are more stringent than those adopted by the
Environmental Protection Agency ("EPA") under the Act. Revisions to the Act have
expanded the type of emissions monitored and provided the regulatory agencies
more authority to enforce permits and issue fines. As provisions in the Act are
implemented, the regulations and enforcement practices will force industry to
take a more proactive approach toward the operation and maintenance practices of
their facilities, which may have a positive impact on the Company.

In November 1996, the EPA announced its intentions to promulgate new National
Ambient Air Quality Standards (NAAQS) for the control of particulate matter
("PM"), which includes lead, ground-level ozone, sulfur dioxide, nitrogen
dioxide, carbon monoxide and other fine particulate matter. Currently, the
States do not monitor for small particulate (less than 2.5 microns), therefore
very little data has been collected to determine which areas meet or do not meet
the revised PM-fine standards. On December 1, 1996, the EPA proposed new and
more stringent monitoring requirements for PM-2.5 in conjunction with the
proposed NAAQS for fine particles. If the proposed regulations are put into
effect, different versions of the PM-2.5 monitoring networks will be required in
large metropolitan areas, small cities and rural areas, and each state will have
to prepare a State Implementation Plan that documents its


                                      -10-




<PAGE>


approach to meeting the new NAAQS. The network of required monitors will be
phased in over a three to four year period beginning in 1998. When considering
the proposed regulations, the industries most likely to be impacted by the
changing air quality standards are the utility, automotive, chemical, petroleum
and manufacturing industries. The Company believes that the growing awareness of
the importance for better air quality and the adoption of the proposed
regulations are positive long-term indicators of the Company's growth potential.
Further, the Company is not aware of any likely statutory changes that may have
a negative impact on its business.

Additionally, the Company manufactures and sells its products in Europe, Latin
America, Canada, the Near East, the Pacific Rim and China. The Company's
international customers, as do the domestic customers, operate in compliance
with certain standards established and promulgated by the permitting
authorities.

BACKLOG

On September 30, 1999, the backlog of orders for replacement parts and
industrial services was $47.2 million compared to $51.5 million at September 30,
1998 and $40.8 million at September 30, 1997. The lower backlog at September
1999 is the result of large ESP projects that were in the September 1998
figures. The September 1999 backlog has increased as compared to the prior year
for the Company's European business and its domestic fabric filter products. The
Company believes that more than 75% of its backlog is shippable by September 30,
2000.

EMPLOYEES

As of September 30, 1999, the Company employed approximately 1,050 persons, none
of whom are represented by labor unions. The Company restricts access to its
database and customarily requires its employees having access to proprietary
systems and information to execute confidentiality agreements and covenants not
to compete. The Company believes that its relations with its employees are good.

PATENTS, TRADEMARKS, COPYRIGHTS, AND PROPRIETARY INFORMATION

The Company owns patents, trademarks, and proprietary information and has
pending applications for patent, trademarks, and copyrights for parts,
accessories, and training materials for industrial air pollution control
equipment and non-air pollution control markets. The Company considers such
patents, trademarks, and proprietary information and applications for patents,
trademarks, and copyrights to be important. The business of the Company,
however, is not dependent on such patents, trademarks, and proprietary
information. Patents owned by the Company are enforceable from 2000
through 2016.

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

GENERAL

For purposes of this "Management's Discussion and Analysis" as well as the
segment reporting information included in Note 7 to the Audited Financial
Statements, Domestic Air Pollution Control ("Domestic APC") represents all
business for which the products or services are sold or managed from the United
States. Generally, this includes revenues to customers in the U.S. and exports
to customers in Canada, Latin America, and Asia. Europe APC represents all
business for which the products or services are sold or managed primarily from
Europe. Such revenues are typically generated in Europe and Northern Africa. BHA
Technologies, a subsidiary engaged in the production and sale of ePTFE membrane
for both APC and non-APC applications, represents BHA's third business segment.

FISCAL 1999 COMPARED TO FISCAL 1998

Consolidated net sales for BHA during the year ended September 30, 1999 ("fiscal
1999") were $155.7 million compared to $142.4 million during the year ended
September 30, 1998 ("fiscal 1998"), an increase of 9%. Domestic APC contributed
the majority of the increase due to continued growth in sales of fine filtration
products and an unusually strong year for sales of electrostatic precipitator
("ESP") replacement parts and services that resulted from a number of contracts
for large rebuild projects. Primarily as a result of the growth in fine
filtration, sales of fabric filter products and services in baghouse
applications within the U.S. and Canada increased 7% to $79.0 million. Sales of
electrostatic precipitator parts and services in the U.S. and Canada increased
42% to $37.6 million. These increases more than offset declines in export sales
by the Domestic APC business segment. Economic difficulties in BHA's key Asian
and Latin American markets contributed to a 19% decline in export sales to $17.2
million. Sales in Europe were essentially unchanged at $20.1 million. BHA
Technologies increased its sales to third parties from $0.9 million to $1.8
million.

GROSS MARGIN

Consolidated gross margin was 26.9% of sales in fiscal 1999 compared to 30.9% of
sales in 1998. The margins in fiscal 1999 were adversely impacted by several
factors: (1) a cost overrun on a large fixed-price ESP rebuild project on which
a loss of $2.4 million was recognized, (2) substantial experimentation and
testing performed by BHA Technologies totaling $1.4 million related to adhesive
lamination to develop non-APC products, and (3) inventory write-downs of $0.4
million attributable to the Company's consolidation of manufacturing operations
in Europe. Excluding these three factors, gross margins were 29.6% in fiscal
1999. The balance of the decline in the gross margin percentage is largely the
result of a decline in gross margins as a percentage of sales in Europe due to a
combination of excess capacity and competition.


                                      -16-






<PAGE>


OPERATING EXPENSES

Selling and advertising expense as a percentage of sales was 13.0% in fiscal
1999 and 12.2% of sales in fiscal 1998. The increased expense as a percentage of
sales was the result of investments being made to develop new markets by BHA
Technologies in non-APC businesses and additional personnel hired and trained
during the year to pursue future APC sales in new domestic and international
markets. General and administrative expense increased from $14.5 million to
$15.9 million but remained constant at 10.2% of sales in both fiscal 1999 and
1998. Approximately $0.5 million of the increased cost was the result of higher
reserves for doubtful receivables, primarily in Europe.

Restructuring expenses in the amount of $2.2 million were recognized during
fiscal 1999. A charge of $1.7 million was taken as a result of the decision by
BHA Technologies to discontinue its in-house adhesive lamination efforts and to
write down the related equipment to its net realizable value. Future efforts to
sell ePTFE membrane for apparel and other uses involving adhesive lamination
will either be outsourced or will be in the form of unlaminated film.
Additionally, severance costs of $0.5 million was incurred relative to the
consolidation of manufacturing operations in Europe.

INTEREST EXPENSE

Interest expense for fiscal 1999 and 1998 was $2.1 million and $1.4 million,
respectively. The increase was attributable to an increase in average
borrowings, including a capital lease. Such borrowings were used to fund
increased working capital requirements, investments in capital equipment, and
treasury stock repurchases.

INCOME TAXES

The effective income tax rate was 34.7% in fiscal 1999 compared to 31.8% in
fiscal 1998. The increase was the result of tax benefits recorded relative to
certain foreign losses at rates of less than 30% in fiscal 1999.

NET EARNINGS

Net earnings were $1.1 million ($0.15 per share) in fiscal 1999 and $7.3 million
($0.97 per share) in fiscal 1998. The decreased earnings is the result of
restructuring charges and substantial operating losses incurred in Europe and by
BHA Technologies together with the cost overrun on the ESP project discussed
above. Weighted average common and common equivalent shares outstanding
decreased by 0.4 million shares primarily due to treasury stock repurchases.

OTHER

The U.S. inflation rate grew at a moderate pace during 1999. BHA believes that
its business is not affected by inflation, except to the extent the economy in
general is affected.

FISCAL 1998 COMPARED TO FISCAL 1997

Consolidated net sales for BHA during fiscal 1998 were $142.4 million compared
to $130.6 million during the year ended September 30, 1997 ("fiscal 1997"), a 9%
improvement. The overall change included a 26% increase in sales of
electrostatic precipitator replacement parts and services in the U.S. and
Canada. The improvement in sales to $26.4 million was due to an increase in
major project work in both the electric utility and industrial markets. Sales of
fabric filter products and services in baghouse applications in the U.S. and
Canada increased 3% to $74.1 million during fiscal 1998 as sales of BHA's fine
filtration products showed continued growth. Export sales from the U.S. in
fiscal 1998 were $21.4 million which was consistent with the prior year. Fiscal
1998 sales in Europe were $20.5 million representing a 25% increase over the
prior year. The fiscal 1998 results included the sales of Purfilter in Spain
which was acquired during that year. Sales in Europe, exclusive of Purfilter,
increased 10% over fiscal 1997.

GROSS MARGIN

Consolidated gross margin as a percentage of sales was 30.9% and 31.2% during
fiscal 1998 and 1997, respectively. During fiscal 1998, BHA's U.S. sales of
fabric filter products and services generated an improved gross margin
percentage due to a sales mix favoring its fine filtration product lines. The
increase was offset by an overall lower blended gross margin percentage in the
rest of its business caused by the combination of an increase in sales of lower
gross margin ESP replacement parts and services in the U.S., a decrease in
higher gross margin sales to customers in Asia and a decrease in the gross
margin percentage on sales in Europe.

OPERATING EXPENSE

Selling and advertising expense as a percentage of sales was 12.2% and 11.4% for
fiscal 1998 and 1997, respectively. The increase during fiscal 1998 was largely
attributable to higher selling expense relating to BHA Technologies' efforts in
pursuing opportunities outside of air pollution control. General and
administrative expense as a percentage of sales was 10.2% in both fiscal 1998
and 1997.

INTEREST EXPENSE

Interest expense for fiscal 1998 and 1997 was $1.4 million and $1.0 million,
respectively. The increase was attributable to an increase in bank borrowings
during fiscal 1998 to fund acquisitions, capital expenditures and treasury share
repurchase.

INCOME TAXES

The effective income tax rates were 31.8% and 30.1% in fiscal 1998 and 1997,
respectively. The increase was attributable to a decrease in research and
experimentation tax credits earned during fiscal 1998 as compared to the prior
year.


                                      -18-






<PAGE>


NET EARNINGS

Net earnings were $7.3 million ($0.97 per share) in fiscal 1998 and $8.1 million
($1.06 per share) in fiscal 1997. The decrease in net earnings was attributable
to a decline in profits relating to BHA's international APC businesses and
operating losses incurred in BHA Technologies. Weighted average common and
equivalent shares outstanding decreased by 0.1 million shares due to treasury
stock repurchases.

LIQUIDITY AND CAPITAL RESOURCES

Net working capital was $43.3 million at September 30, 1999 compared to $42.2
million at September 30, 1998. The current ratio was 3.3 in 1999 compared to a
current ratio of 3.1 in 1998. Cash provided by operating activities was $9.2
million during fiscal 1999 while cash used by operating activities was $3.9
million in 1998. In fiscal 1997, $10.6 million in cash was provided by operating
activities. The positive cash flow provided by operating activities in fiscal
1999 reflects a modest $1.1 million increase in working capital to support the
$13.3 million increase in sales. The large use of cash in fiscal 1998 was the
result of a substantial increase in accounts receivable and inventory during
that year.

Investing activities have resulted in a net use of cash during each of the past
three years. Capital expenditures were $5.8 million, $8.3 million, and $10.5
million in fiscal 1999, 1998, and 1997, respectively. Capital expenditures over
the past three years have been used to expand capacity for ePTFE membrane,
invest in improved information systems, and develop new products and increased
manufacturing capacity for BHA's APC products. Additional investments in recent
years include the acquisitions of product rights relative to Drayton's sound-off
acoustic cleaner product line in 1999 and acquisitions of APC businesses in
Spain and Venezuela in 1998.

During fiscal 1999, net cash provided by financing activities was approximately
$0.1 million as cash generated from operations was sufficient to support the
Company's investing activities. Incremental borrowings of $3.9 million were
largely used to repurchase BHA stock. In fiscal 1998, the Company incurred $14.4
million in incremental borrowings in order to fund the operating and investing
activities as well as repurchase $1.8 million of BHA stock. During fiscal 1997,
net cash provided by financing activities of $0.3 million included a net
increase in bank borrowings of approximately $3.6 million of which $2.7 million
was used to repurchase BHA stock.

At September 30, 1999, BHA had unused lines of credit of $17.5 million. During
the year, BHA refinanced most of its borrowings resulting in a year end debt
structure that includes commitments for: an $18.0 million revolving credit
facility maturing on October 1, 2002; a $15.0 million amortizing term loan with
a final maturity in 2006; a $2.5 million term loan with a maturity in June 2000;
German term loan and revolving credit facilities totaling the U.S. equivalent of
$4.1 million and maturing in 2003; and a capital lease related to an industrial
revenue bond transaction for $8.0 million with annual sinking fund payments and
a final maturity in 2018.


                                      -19-






<PAGE>


The domestic term loans and revolving credit facility include financial
covenants regarding minimum net worth, minimum fixed charge coverage ratios, and
maximum borrowing to EBITDA ratios. The Company was in compliance with all such
covenants at September 30, 1999. With the exception of the capital lease
transaction, no assets of the Company are pledged to secure any indebtedness.
BHA believes that cash flows from operations and available credit lines will be
sufficient to meet its capital needs for the foreseeable future.

YEAR 2000

The Company has established a task force to address and assess Year 2000
compliance for the Company's computer system and software applications, its
facilities throughout the world, the products it sells that include
date-sensitive microprocessors, and suppliers providing the Company with goods
and services.

THE STATE OF READINESS OF THE COMPANY

During the past several years, the Company has replaced its significant computer
software applications through normal system upgrades. These computer systems
include personal computers, mid-range computer systems, and worldwide network
applications. All of the new systems are, according to the software vendors,
Year 2000 compliant to support the proper processing of date-sensitive
transactions. Internal testing of all of the Company's critical computer systems
and software applications have been completed. Corrective actions remaining
generally consist of installing "Y2K patches" to be provided by personal
computer software vendors.

The task force has also finalized its review of inventory lists of all
machinery, office equipment, and building equipment that utilize microprocessors
at the Company's facilities around the world. The Company has identified all
Year 2000-compliance issues which the Company believes could have a material
impact on the business and has completed final system testing and all
remediation believed to be significant.

The Company has a number of products that have date-sensitive microprocessors.
The task force has identified those products that have Year 2000 compliance
issues and proactively notified the customers to whom these products have been
sold, providing recommendations regarding actions to be taken by the customer.

The task force has prepared a list of significant suppliers of goods and
services whose Year 2000 compliance could potentially impact the Company's
business. The Company has proactively addressed and evaluated Year 2000
compliance with these suppliers, determining the impact on the Company's
business and developing necessary contingency plans. The Company will continue
to monitor the impact of any changes in key suppliers' announcements regarding
Year 2000 readiness.


                                      -20-






<PAGE>


THE COSTS OF YEAR 2000 COMPLIANCE

The costs incurred to upgrade the Company's computer systems and software
applications were normal, planned system upgrades. In 1996, the Company made the
decision to consolidate its business into one entity for operating purposes.
This consolidation process included an upgrade to the Company's primary
mid-range legacy computer systems. The Company believes that all Year 2000
issues were addressed and corrected at that time. The Company completed its
personal computer rollout during 1998. The rollout was part of an overall
strategy to standardize on a single platform using a current level of
technology. Based on representations received from vendors, the Company believes
that all new equipment and software purchased is Year 2000 compliant.

The costs associated with the Year 2000 compliance of the Company's equipment
was not material. The company believes that the costs associated with any
potential non-compliance of the Company's products for Year 2000 are mitigated
by the Terms and Conditions under which these products were sold. The Company's
Terms and Conditions do not include any representations or warranties regarding
Year 2000 compliance and exclude any liability for incidental or consequential
damages including those which could arise out of a Year 2000 issue. The Company
does not anticipate that the costs associated with Year 2000 relating to its
products will be material.

The costs associated with the Year 2000 compliance of the Company's suppliers of
goods and services are not expected to be material. These plans will include
procuring additional quantities of inventory from certain vendors during the
fourth quarter of calendar 1999, but such incremental inventories, which will be
temporary, are not expected to exceed $2.0 million.

The Company does not separately track the internal costs incurred relating to
Year 2000 compliance since theses costs are principally payroll and related
costs for the task force and Management Information Systems department.

THE RISKS OF YEAR 2000 NON-COMPLIANCE TO THE COMPANY

The task force believes that the most significant risk that relates to Year 2000
compliance may be the state of readiness of the Company's significant suppliers
of goods and services, especially those outside of the U.S. Although the Company
has taken a proactive approach to communicate with its suppliers, the Company's
relationship with these suppliers cannot ensure their Year 2000 compliance or
their ability to continue to provide the necessary goods and services to the
Company.

Although the Company has completed the evaluation and testing of all of its
business systems, products, and vendor relationships, the Year 2000 readiness is
largely dependent upon numerous entities outside of the direct control of BHA.
The Company can make no guarantee that such factors will not have a material
adverse impact on the Company or its operations.


                                      -21-






<PAGE>


THE YEAR 2000 CONTINGENCY PLANS OF THE COMPANY

The task force believes that its contingency plans are substantially complete,
however, due to the inter-relationship of numerous entities throughout the
world, management recognizes that new issues could develop that would require a
change in such plans. The Company will continue to monitor events domestically
as well as internationally.

NEW ACCOUNTING PRONOUNCEMENTS

Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities" is effective for BHA's fiscal
year 2001. The statement establishes accounting and reporting standards for
derivative instruments and all hedging activities. This statement will not have
any impact on BHA's results of operations as all derivative instruments are
designated as hedges against foreign currency exposures.

FORWARD LOOKING INFORMATION

This report contains forward-looking statements that reflect BHA's current views
with respect to future events and financial performance. The statements are
subject to certain risks and uncertainties that could cause actual results to
differ materially from historical results or those anticipated. The words
"should," "believe," "anticipate," "expect," and other expressions that indicate
future events and trends identify forward-looking statements. Actual future
results and trends may differ materially from historical results or those
anticipated depending on a variety of factors, including, but not limited to,
competition, the performance of newly established domestic and international
operations, demand and price for BHA's products and services, and other factors.
You should consult the section entitled "Factors Affecting Earnings and Stock
Price".

ITEM 7A - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

FORWARD EXCHANGE CONTRACTS

BHA periodically enters into forward exchange contracts in order to fix the
currency exchange rate related to intercompany transactions with its foreign
subsidiaries. Changes in the value of these instruments due to currency
movements offset the foreign exchange gains and losses of the corresponding
intercompany transactions. At September 30, 1999 and 1998, the aggregate amount
of such forward exchange contracts was approximately $2,400,000 and $1,950,000,
respectively. The fair value of the outstanding forward exchange contracts
approximates the aggregate amount outstanding at September 30, 1999.

standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of BHA Group Holdings,
Inc., and subsidiaries at September 30, 1999 and 1998, and the results of their

                   Notes to Consolidated Financial Statements


1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       PRESENTATION
       The consolidated financial statements include the accounts of BHA Group
       Holdings, Inc. (BHA) and its wholly-owned foreign and domestic
       subsidiaries. All significant intercompany balances and transactions have
       been eliminated in consolidation.

       REVENUE RECOGNITION
       BHA recognizes revenue at the time products are shipped or services are
       performed.

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

       INVENTORIES
       BHA values its inventory at the lower of cost or market. Cost is
       determined using the first-in, first-out (FIFO) method. Components of
       inventories at September 30, 1999 and 1998 were as follows:

       PROPERTY, PLANT AND EQUIPMENT
       Property, plant and equipment are carried at cost. Major renewals and
       betterments are charged to the property accounts; replacements,
       maintenance and repairs that do not improve or extend the life of the
       respective assets are charged to expense as incurred.

       DEPRECIATION AND AMORTIZATION
       Depreciation and amortization of property, plant and equipment are
       computed on the straight-line method using estimated useful lives by
       major asset class as follows:

                 Buildings and improvements                          30 years
                 Machinery and equipment                             4-8 years
                 Office furniture, fixtures and equipment            3-10 years

       INCOME TAXES
       Deferred tax assets and liabilities are recognized for the future tax
       consequences attributable to differences between the financial statement
       carrying amounts of existing assets and liabilities and their respective
       tax bases. Deferred tax assets and liabilities are measured using enacted
       tax rates expected to be recovered or settled. The effect on deferred tax
       assets and liabilities of a change in tax rates is recognized in earnings
       in the period that includes the enactment date.

       No provision is made for income taxes on undistributed earnings of the
       foreign subsidiaries because such earnings are considered permanently
       invested in the foreign subsidiaries.

       WARRANTY AND PRODUCT SERVICE
       BHA provides a reserve for estimated warranty and product service claims
       based on historical experience and consideration of changes in products
       and technology.

       FOREIGN CURRENCY TRANSLATION
       Financial statements of BHA's foreign subsidiaries are translated into
       U.S. dollars at current and average exchange rates. Translation gains and
       losses are included in other comprehensive income. Transaction gains and
       losses resulting from fluctuations in exchange rates between the
       functional currency (U.S. dollars) and the currency in which a foreign
       currency transaction is denominated are included in net earnings.
       Transaction gains included in the consolidated statements of earnings for
       1999, 1998 and 1997 amounted to $71,000, $141,000 and $93,000,
       respectively.

       FORWARD EXCHANGE CONTRACTS
       BHA periodically enters into forward exchange contracts in order to fix
       the currency exchange rate related to intercompany transactions with its
       foreign subsidiaries. Changes in the value of these instruments due to
       currency movements offset the foreign exchange gains and losses of the
       corresponding intercompany transactions. At September 30, 1999 and 1998,
       the aggregate amount of such forward exchange contracts was approximately
       $2,400,000 and $1,950,000, respectively. The fair value of the
       outstanding forward exchange contracts approximates the aggregate amount
       outstanding at September 30, 1999.

       COMPREHENSIVE INCOME
       In June 1997, the Financial Accounting Standards Board issued Statement
       No. 130, "Reporting Comprehensive Income" which establishes rules for the
       reporting of comprehensive income and its components. Comprehensive
       income consists of net income and foreign currency translation
       adjustments and is presented in the Statement of Comprehensive Income.
       The adoption of Statement No. 130 had no impact on net earnings or
       stockholders' equity of the Company.

       TREASURY STOCK
       Since June 1994, the Board of Directors of BHA have periodically approved
       the purchase of up to 2,000,000 shares of the Company's common stock. The
       purchases of common stock are recorded at cost on the date of purchase.
       Issuance of common stock from the treasury is recorded at the average
       cost of common stock held in the treasury.

       EARNINGS PER COMMON SHARE
       Basic earnings per share is computed by dividing net earnings available
       to common shareholders by the weighted average number of common shares
       outstanding for the period. Diluted earnings per share is computed based
       upon the weighted average number of common shares and dilutive common
       equivalent shares outstanding. Stock options, which are common stock
       equivalents, have a dilutive effect on earnings per share in all periods
       presented and are therefore included in the computation of diluted
       earnings per share. Stock options are described in Note 5. A
       reconciliation of the numerators and the denominators of the basic and
       diluted earnings per-share computations is as follows:

       Options to purchase 571,688 shares of common stock at prices ranging from
       $12.02 to $16.82 per share were outstanding at the end of 1999 but were
       not included in the computation of diluted earnings per share because the
       options' exercise price was greater than the average market price of the
       common shares. In 1998 and 1997, options to purchase 8,800 shares and 0
       shares, respectively, were similarly excluded from the calculation.

       COST IN EXCESS OF NET ASSETS ACQUIRED AND INTANGIBLE ASSETS
       Cost in excess of net assets acquired is being amortized over periods
       ranging from thirty to forty years, and is presented in the accompanying
       consolidated balance sheets net of accumulated amortization of $1,360,000
       and $1,165,000 at September 30, 1999 and 1998, respectively.

       Intangible assets are being amortized over periods ranging from five to
       seventeen years and are presented in the accompanying consolidated
       balance sheets net of accumulated amortization of $5,833,000 and
       $5,482,000 at September 30, 1999 and 1998, respectively.

       IMPAIRMENT OF LONG-LIVED ASSETS
       Long-lived assets and certain identifiable intangibles are reviewed for
       impairment whenever events or changes in circumstances indicate that the
       carrying amount may not be recoverable. Recoverability of assets to be
       held and used is measured by comparison of the carrying amount of the
       asset to future net cash flows expected to be generated by the asset. If
       such assets are considered to be impaired, the impairment to be
       recognized is measured by the amount by which the carrying amount of the
       assets exceed the fair value of the assets. Assets to be disposed of are
       reported at the lower of the carrying amount or fair value less costs to
       sell.


                                      -31-






<PAGE>


       STATEMENTS OF CASH FLOWS
       For purposes of the consolidated statements of cash flows, BHA considers
       overnight invested cash and investments in marketable securities, with
       maturities of three months or less to be cash equivalents.

       FAIR VALUE OF FINANCIAL INSTRUMENTS
       The carrying amounts of cash, accounts receivable and accounts payable
       approximate fair value because of the short maturities of these
       instruments. The fair value of long-term obligations are estimated by
       discounting future cash flows using current market rates. The carrying
       amounts of long-term debt and lease obligations approximate fair value at
       September 30, 1999.

2.     ACQUISITIONS

       In January 1999, the Company acquired certain assets, including patents,
       trademarks, and other intangibles related to Drayton Corporation's
       Sound-Off Acoustic Cleaner product line. The purchase price consists of a
       cash payment of $700,000 plus additional contingent payments to be made
       over the next five years based upon revenues of the product line. The
       Company recorded additional purchase price of $800,000 at the date of
       acquisition based on their assessment of the likelihood of attaining such
       additional revenues. The total purchase price of $1,500,000 is being
       amortized on a straight-line basis over ten years.

       During fiscal 1998, the Company acquired 100% of the outstanding stock of
       Purificacion y Filtracion, S.L. (BHA Purfilter) located in Barcelona,
       Spain and Industrial Filtrantes Purfilter C.A. (BHA Venezuela) located in
       Puerto Ordaz, Venezuela for a combined purchase price of approximately
       $1,400,000. These acquisitions were accounted for as purchases, with each
       purchase price allocated to the assets acquired based upon estimated fair
       values as of the dates of the acquisitions. The excess of the purchase
       price over the net assets acquired is being amortized on a straight-line
       basis over thirty years.

       The proforma effect of these acquisitions are not material to the
       Company.

       BHA has a domestic unsecured bank line of credit of $18,000,000 for
       working capital purposes and other corporate matters. This line of credit
       bears interest at variable rates based on either the prime rate or LIBOR
       and expires in October 2002. This facility is a revolving credit
       agreement in which BHA pays a 0.25% commitment fee on the unused portion.
       At September 30, 1999, $1,120,000 was outstanding under this domestic
       bank line of credit at an interest rate of 7.25%.

       BHA also maintains a foreign unsecured bank line of credit of DM
       2,500,000 (approximately $1,367,000 at September 30, 1999) for working
       capital purposes in Europe. This line of credit bears interest at
       variable rates based on the German prime rate and expires in fiscal 2002.
       At September 30, 1999, DM 1,340,000 (approximately $732,000) was
       outstanding under this foreign bank line of credit at an interest rate of
       4.1%.

       BHA's foreign subsidiary located in Switzerland maintains a line of
       credit with a foreign bank in the amount of CHF 200,000 (approximately
       $133,000 at September 30, 1999). As of September 30, 1999 and 1998, there
       were no borrowings outstanding under this line of credit.

       In September 1999, BHA entered into a $15 million unsecured term loan,
       the proceeds of which were used to repay existing long-term debt and
       provide for general corporate matters. This term loan has a variable
       interest rate based on LIBOR (6.23% at September 30, 1999) and matures in
       October 2006. Quarterly principal payments of $625,000 begin in October
       2000.

       In October 1998, BHA's German subsidiary entered into a DM 5,000,000 term
       loan (approximately $2,733,999 at September 30, 1999) with a German bank.
       The proceeds of the loan were used for working capital purposes. This
       term loan has a fixed rate of 4.75% and is due in full at maturity in
       December 2003.

       BHA also has a $2.5 million unsecured term loan which was renewed during
       fiscal year 1999 with an interest rate of 5.0% and matures in June 2000.

       The term loans and domestic bank line of credit require BHA, among other
       things, to maintain minimum levels of net worth, minimum fixed charge
       coverage, minimum current ratio, and maximum debt to cash flow ratio. BHA
       was in compliance with all covenants at September 30, 1999. At September
       30, 1999, $9,500,000 of retained earnings were available for cash
       dividends.

       Capital Lease Obligations
       In December 1998, BHA Technologies, Inc., a wholly-owned subsidiary,
       entered into a sale-leaseback transaction with the City of Lee's Summit,
       Missouri. In connection with this lease, the city issued tax-exempt
       Industrial Development Revenue Bonds ("Bonds") totaling $8,000,000 and
       placed the proceeds in a trust to fund future capital expenditures at the
       Lee's Summit manufacturing facility. BHA Technologies is obligated,
       through its lease, for the repayment of these bonds over the next 20
       years. Annual lease payments of $400,000 begin in December 1999. The
       interest rate on the tax-exempt Bonds is variable based on a weekly
       published index that is approximately 67% of LIBOR (3.50% as of September
       30, 1999). As of September 30, 1999, BHA Technologies has $1.2 million in
       restricted cash held in trust for the exclusive use for qualified capital
       expenditures in Lee's Summit. The restricted cash is included in
       Intangible and Other Assets at September 30, 1999.

       Scheduled payments on long-term debt, including capital lease
       obligations, for the next five fiscal years are as follows:

BHA has not recorded a valuation allowance relating to deferred tax assets, as
taxable temporary differences are expected to be offset by deductible temporary
differences and future taxable income.

BHA has not provided deferred taxes on the cumulative undistributed earnings of
its foreign subsidiaries, which approximate $1,627,000, $2,702,000 and
$2,142,000 at September 30, 1999, 1998, and 1997, respectively, as management
considers these earnings to be permanently invested. Net earnings (losses) of
these foreign subsidiaries were approximately $(3,449,000), $359,000 and
$1,058,000 for the years ended September 30, 1999, 1998, and 1997, respectively.

5.     INCENTIVE STOCK PLAN

BHA has an incentive stock plan for key employees, officers and directors. The
plan provides for 2,221,084 shares of common stock (as adjusted for the dilutive
effect of stock dividends) available for issuance of stock options, restricted
stock and payment to outside directors in lieu of cash. Stock options are
granted at a price equal to the fair market value of BHA Common Stock at the
date of grant for terms of up to ten years.

During 1995, BHA awarded 45,000 shares of restricted stock, under the incentive
stock plan, to certain employees. The market value of the awards at the date of
issuance has been recognized as compensation expense ratably over the five-year
vesting period ending in fiscal 1999.

BHA accounts for its stock-based employee compensation plans pursuant to
Statement of Financial Accounting Standard No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123). SFAS 123 establishes a fair value-based method of
accounting. BHA has chosen to adopt the pro-forma disclosure requirements of
SFAS 123, and continue to record stock compensation in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" (APB 25) which is permitted under SFAS 123. Under APB 25 compensation
expense is recorded on the date of grant for stock options granted only if the
current market price of the underlying stock exceeds the exercise price.

A summary of transactions in the incentive stock plan is as follows:

The per share weighted-average fair value of stock options granted during 1999,
1998, and 1997 was $5.36, $5.20 and $5.44, respectively, on the date of grant
using the Black Scholes option-pricing model with the following assumptions:
expected dividend yield of 1.15% for 1999, .80% for 1998, and 1.00% for 1997;
weighted average risk-free interest rate of 5.90% for 1999, 4.73% for 1998, and
6.10% for 1997; expected volatility factor of 29.38%, 19.0% and 18.9% for 1999,
1998, and 1997, respectively; and a weighted-average expected life of eight
years.

Since BHA applies APB 25 in accounting for its incentive stock plan, no
compensation expense has been recognized for stock options in net earnings.
Stock-based compensation expense, if recorded under SFAS 123 would have reduced
net earnings by $738,000 or $.10 per diluted share in 1999, $470,000 or $.06 per
diluted share in 1998, and $12,000 in 1997 with no effect on earnings per share.

Compensation expense for options granted prior to October 1, 1995 is not
considered. The full impact of calculating compensation expense for stock
options under SFAS 123 is not reflected in the proforma net earnings amounts
above since compensation expense is reflected over the option's vesting period
of four years for all options.

6.     COMMITMENTS AND CONTINGENT LIABILITIES

EMPLOYEE BENEFIT PLANS
BHA has a noncontributory Employee Stock Ownership Plan (ESOP) which includes
substantially all domestic employees who are not covered by collective
bargaining agreements. BHA, with approval of its Board of Directors, makes
discretionary contributions to the ESOP. Benefits become vested according to
years of service. Contributions charged to operating expense were $435,000,
$884,000, and $1,175,000 for the years ended September 30, 1999, 1998, and 1997,
respectively.

BHA's eligible domestic employees participate in a voluntary 401(k) employee
benefit plan (401(k) Plan). The 401(k) Plan covers eligible employees not
covered by a collective bargaining agreement. The 401(k) Plan provides that 100%
of a participant's contribution will be matched by BHA subject to a maximum
contribution which is determined annually at the discretion of the Board of
Directors. BHA matching contributions become vested based on years of service.
BHA made matching contributions of $330,000, $270,000, and $253,000 for the
years ended September 30, 1999, 1998, and 1997, respectively.

<PAGE>


It is expected that in the normal course of business, expiring leases will be
renewed or replaced by similar leases on other properties. Total rental expense
on noncancelable, long-term operating leases amounted to approximately
$2,780,000, $2,210,000 and $1,036,000 for the years ended September 30, 1999,
1998, and 1997, respectively.

LETTERS OF CREDIT
The terms of certain contracts require that BHA issue standby letters of credit
to assure performance. Open standby letters of credit amounted to $92,000 and
$57,000 at September 30, 1999 and 1998, respectively.

LITIGATION
In the normal course of business, BHA is party to certain actions arising out of
various allegations of product or professional liability. BHA has insurance
coverage for substantially all such actions, subject to coverage limitations and
deductibles for each claim. In the opinion of management, the amount of loss, if
any, from the final outcome of these actions will not have a material adverse
impact on the consolidated financial statements.

7.     RESTRUCTURING

The Company recognized restructuring expenses in the amount of $2,167,000 on a
pretax basis during the fourth quarter of fiscal 1999. A charge of $1,713,000
was taken as a result of the decision by BHA Technologies to discontinue its
in-house adhesive lamination efforts. The charge primarily related to the
write-down of lamination equipment to its net realizable value. Future efforts
to sell PTFE membrane for apparel and other uses involving adhesive lamination
will either be outsourced or will be in the form of unlaminated film.
Additionally, severance cost of $454,000 was expensed and paid during the fourth
quarter relative to the consolidation of manufacturing operations in Europe. In
June, the Company announced a decision to combine its European fabric filter
manufacturing into one facility located in Spain. As part of this consolidation,
the manufacturing facility in Germany was closed effective September 30, 1999.

In addition, cost of sales includes Unusual Charges of $4,200,000 consisting of
(1) a cost overrun on a large fixed-price ESP rebuild project on which a loss of
$2,400,000 was recognized, (2) substantial experimentation and testing performed
by BHA Technologies totaling $1,400,000 related to adhesive lamination to
develop products for non-APC markets and (3) inventory write-downs of $400,000
attributable to the Company's consolidation of manufacturing operations in
Europe.

8.     BUSINESS SEGMENTS

SEGMENT REPORTING
Effective September 30, 1999, BHA adopted Statement of Financial Accounting
Standard No. 131, "Disclosures about Segments of an Enterprise and Related
Information," (SFAS No. 131). SFAS No. 131 requires reporting of segment
information that is consistent with the way in which management operates the
Company. The disclosure requirements of SFAS No. 131 have been presented for
each of the years ended September 30, 1999, 1998 and 1997.


                                  -38-




<PAGE>

BHA reports its operations as three business segments, Domestic Air Pollution
Control (Domestic APC), Europe Air Pollution Control (Europe APC), and BHA
Technologies. Domestic APC consists of the air pollution control products and
services sold or managed from the United States. Such sales include shipments
and services throughout North America, Latin America, Asia, and the Pacific Rim
as such revenues are derived from BHA's U.S. based management group. The Europe
APC segment represents sales of products and services managed from BHA's
European manufacturing, distribution, and sales offices. BHA Europe generally
services customers throughout Europe, as well as in Northern Africa. BHA
Technologies supplies ePTFE membrane products to BHA's APC business and is also
developing a market for such products outside of air pollution control.

The accounting policies for the segments are the same as those described in the
summary of significant accounting policies. BHA manages these segments as
strategic business units. Europe APC represents a distinct business unit as it
maintains its own manufacturing, sales, marketing, and project management
resources. Sales to other international locations are included in the Domestic
APC business segment, as most or all of the key manufacturing, engineering, and
sales support functions are performed from the United States. BHA Technologies
operates as a distinct entity due to its unique technologies, as well as the
marketing of products unrelated to air pollution control.

Reportable segment data for the years ended September 30, 1999, 1998, and 1997
were as follows:

The proceeds of the Loan will first be used to repay all sums due from Borrower
to Bank in connection with Borrower's existing Fifteen Million Dollar
($15,000,000) revolving line of credit at Bank, and the balance of the proceeds,
if any, shall be used to pay down any other outstanding bank debt.

                1.03. TERM NOTE. On the date of closing Borrower will execute
and deliver its promissory note to Bank, in form and substance satisfactory to
Bank, and in the principal amount of the Loan (the "TERM NOTE").

                1.04. INTEREST.

                (a) Accrued interest on the Loan shall be calculated on the
        actual number of days outstanding based on a year consisting of 360
        days. Interest after or during the continuation of any Event of Default
        under Section 7.01 shall be at a rate equal to the Commerce Prime Rate
        plus two percent (2.0%), but not exceeding the maximum rate permitted by
        applicable law (the "DEFAULT RATE").

                (b) Commencing on the date hereof, and continuing until the
        first Principal Payment Date, the interest rate shall be adjusted on the
        first day of each calendar month based upon the then applicable LIBOR
        Rate. Commencing on the first Principal Payment Date, the interest rate
        shall be subject to adjustment based upon the applicable LIBOR Rate and
        the Borrower's Leverage Ratio as herein provided.

                (c) From the date hereof up to the first Principal Payment Date,
        the Loan shall bear interest at a per annum variable rate equal to the
        LIBOR Rate plus eighty-five (85) basis points, payable in monthly
        installments in arrears on the first of each calendar month.

                (d) Commencing on the first Principal Payment Date, the interest
        rate borne by the Loan shall be subject to adjustment (and thereafter
        subject to readjustment) based upon Borrower's Leverage Ratio, as
        defined herein, for the immediately preceding fiscal quarter, as set
        forth below:

<TABLE>
<CAPTION>


                    Leverage Ratio                        Interest Rate
                    --------------                        -------------
                  <S>                          <C>
                  greater than 2.75:1           LIBOR Rate plus 115 basis points
                    2.75:1 to 2.01:1            LIBOR Rate plus 100 basis points
                    2.00:1 to 1.25:1            LIBOR Rate plus 85 basis points
                    less than 1.24:1            LIBOR Rate plus 75 basis points
</TABLE>
        The Borrower's Leverage Ratio shall be determined by reference to
        Borrower's Compliance Certificates, required under Section 4.02 hereof.
        The interest adjustment shall be effective upon the first day of the
        first month following Bank's receipt of Borrower's Compliance
        Certificate for the preceding fiscal quarter and subsequent interest
        adjustments shall similarly be effective on the first day of the first
        month following Bank's receipt of the applicable Compliance Certificate.

                1.05. PRINCIPAL. Commencing on the first Principal Payment Date,
and continuing on each Principal Payment Date thereafter, principal shall be due
in advance in twenty-four (24) equal quarterly installments of Six Hundred
Twenty Five Thousand Dollars ($625,000) each.

                1.06. AUTOMATIC PAYMENT. Borrower hereby authorizes Bank
automatically to deduct from Borrower's Account, number 2340340 (the "ACCOUNT"),
the amount of any Loan payment hereunder, whether interest, principal or other
amounts due hereunder. If the funds in the Account are insufficient to cover any
such payment, Bank shall not be obligated to advance funds to cover such
payment. At any time and for any reason, either Bank or Borrower may voluntarily
terminate such automatic payments, effective upon written notice from one to the
other.

                1.07. FACILITY FEE. A non-refundable facility fee equal to one
percent (1.0%) of the Loan Amount shall be due and payable on the date of
execution of this Agreement to Bank by Borrower. Additionally, a facility fee
equal to one tenth of one percent (0.10%) of the Loan Amount shall be deemed
earned and non-refundable on the date of execution hereof and will be due and
payable on the first Principal Payment Date, or on such earlier date on which
the entire Loan becomes due and payable in full.

                1.08. SWAP OPTION. At any time upon prior written notice,
Borrower may elect to convert all, but not less than all, of the Loan from a
variable interest rate loan to a fixed interest rate loan. Borrower shall give
written notice to Bank of its election to convert the Loan, and such notice
shall specify the date on which Borrower wishes the fixed rate of interest
determined. Bank shall use its best efforts to determine the fixed rate of
interest on the date specified in Borrower's notice but Bank shall have no less
than five (5) Business Days following receipt of Borrower's notice in which to
quote the fixed interest rate to Borrower. Should Borrower elect to convert the
Loan to the rate quoted by Bank, Bank will implement such conversion by entering
into a swap contract (the "SWAP CONTRACT") pursuant to the terms of the 1992
International Swap Dealer's Association Master Loan and Appendices. The fixed
interest rate may only become effective on a regularly scheduled interest
payment date or a Principal Payment Date. The Swap Contract shall bear whatever
interest rate is available at such time. Borrower shall pay all fees and
expenses of Bank in connection with the Swap Contract, including Bank's
reasonable administrative fees to cover its services in implementing the Swap
Contract. In addition, should Borrower wish to prepay the Loan following such
conversion to a fixed rate, Borrower shall pay any and all fees, costs and
expenses incurred by Bank in connection with such prepayment, including, if
necessary, implementation of a second Swap Contract to ensure that Bank suffers
no loss or detriment arising out of Borrower's election to convert the Loan to a
fixed interest rate as herein provided.

                1.09. PREPAYMENT. Provided Borrower has not elected to fix the
interest rate of the Loan pursuant to Section 1.08, Borrower may prepay the
Loan, in part or in full, at any time without the payment of a prepayment fee.
Partial prepayments shall be applied to principal in inverse order of maturity,
and shall not affect the regularly scheduled payments provided for herein.

the Real Property upon the occurrence of any Event of Default (as hereinafter

(including claims for labor, materials and supplies) which, if unpaid, might by
law become a lien or charge upon any of its property, except that nothing herein
contained shall be interpreted to require the payment of any such debt, account,
liability, tax, assessment or charge so long as its validity is being contested

                (a) make any advances to Borrower's Affiliates, including
        without limiting the generality of the foregoing, BHA Technologies,
        Inc., in excess of Four Million Dollars ($4,000,000) in the aggregate
        among all Borrower's Affiliates;

                (b) incur any indebtedness or permit any Affiliate to incur any
        indebtedness of any kind whatsoever, other than (i) indebtedness under
        the Loan Documents; (ii) indebtedness of Borrower or an Affiliate on
        terms approved in advance by Bank in its reasonable discretion and Bank
        hereby approves Borrower's indebtedness to Bank of America in the
        maximum amount of Eighteen Million Dollars ($18,000,000); (iii)
        operating leases, the expenditures for which in any fiscal year do not
        exceed Three Million Five Hundred Thousand Dollars ($3,500,000) in the
        aggregate among Borrower and its Affiliates; (iv) capital lease
        obligations which do not exceed Three Million Dollars ($3,000,000) at
        any time in the aggregate among Borrower and its Affiliates; and (v)
        purchase money indebtedness the outstanding balance of which does not

                (c) undertake, undergo or permit any Change of Control, as such
        term is defined herein. The term "Change of Control" as used with
        respect to Borrower, shall be deemed to occur if (i) the board of
        directors of Borrower approves a sale of all or substantially all of the
        assets of Borrower or provides a positive recommendation with respect to
        any tender offer or approves the terms of any merger, which, in either
        event, will result in the persons who are the shareholders of Borrower
        immediately prior to the consummation of such transaction owning less
        than 50% of the voting securities of Borrower or the resulting entity
        into which Borrower is merged (if Borrower is not the surviving entity
        in such merger) upon consummation of such transaction; or (ii) any
        person, firm or entity, or group of persons, firms or entities acting in
        concert, acquires in excess of 25% of the voting securities of Borrower;

                (d) make any investment in any line of business outside of
        Borrower's primary line of business of the development, manufacturing
        and marketing of filtration devices for industrial air pollution control
        equipment and services related thereto or outside any Affiliate's
        primary line of business;

                (e) incur any Change in Management, as such term is defined
        herein. A "CHANGE IN MANAGEMENT" shall be deemed to occur if the Chief
        Executive Officer and the Chief Operating Officer, as of the date
        hereof, cease to be employees of Borrower.

                (f)   (i) sell or transfer any property or assets to, or
            purchase or acquire any property or assets from, or otherwise engage
            in any other transactions with, any of its Affiliates inconsistent
            with current practices conducted by Borrower and its Affiliates,
            except that the Borrower or any Affiliate may engage in any of the
            foregoing transactions in the ordinary course of business at prices
            and on terms and conditions which, taken as a whole, are not less
            favorable to the Borrower or any Affiliate than would prevail in an
            arm's-length transaction with unrelated third parties;

                     (ii) Notwithstanding the foregoing, Borrower shall be
            permitted to make acquisitions without the prior written consent of
            Bank, provided that: (A) the target company is in the same line of
            business as Borrower; (B) the cash portion of the purchase price for
            any one acquisition does not exceed $15,000,000; (C) the aggregate
            purchase price of all such acquisitions does not exceed 25% of
            Capital Funds, as defined herein; (D) no later than 30 business days
            prior to the consummation of the acquisition, Borrower has provided
            Bank with pro forma financial statements giving effect to the
            acquisition which demonstrate continued compliance with the
            Covenants and Representations contained herein; (E) Borrower or an
            Affiliate is the surviving entity; and (F) the acquisition would not
            result in an event of default under the Credit Agreement. As used
            herein, the term "CAPITAL FUNDS" shall mean Borrower's stockholders'
            equity as defined in accordance with generally accepted accounting
            principles as of the end of the fiscal quarter preceding the date of
            closing of the acquisition; and

                (g) grant or permit a security interest in or a lien or
        encumbrance on any of its assets without Bank's prior written consent,
        except in respect of Permitted Indebtedness.

                  7.02. REMEDIES. Upon an Event of Default, Bank may resort to
any and all security and to any remedy existing at law or in equity for the
collection of the Term Note according to its tenor and enforcement of the
covenants and provisions hereof, including without limiting the generality of
the foregoing, all costs, penalties and expenses owed to the Bank hereunder,
including those relating to any applicable Swap Contract, and Bank's resort to
any remedy shall not prevent the concurrent or subsequent employment of any
other remedy. In addition to the remedies provided herein, in the event the Term
Note is due and payable or upon an Event of Default, the Bank shall have the
right of setoff, without demand or notice to anyone, against the funds of
Borrower or any Affiliate on deposit with it.

                7.03. EXPENSES OF COLLECTION. All reasonable costs, expenses and
liabilities incurred by Bank in collecting or attempting to collect on the Term
Note, including costs and expenses, and all reasonable attorneys' fees in
connection with such matters, and specifically including any costs, charges,
penalties, administrative charges and fees associated with any applicable Swap
Contract, shall constitute a demand obligation of Borrower and shall bear
interest from the date of expenditure until paid at the per annum rate equal to
the Default Rate.

                7.04. WAIVER. Any waiver of an Event of Default by Bank shall
not extend to or affect any subsequent Event of Default. No failure or delay by
Bank in exercising any right hereunder shall operate as a waiver, nor shall any
single or partial exercise of any right preclude the exercise of any other right
hereunder.

                                     CLOSING

of Bank and such extension of time shall in such case be included in computing
interest, if any, in connection with such payment.

                9.02. WAIVERS. No omission or delay by Bank in exercising any
right, power or privilege under the Loan Documents, will impair such right,
power or privilege or be construed to be a waiver of any Event of Default or
acquiescence therein and any single or partial exercise of any right, power or
privilege will not preclude other or further exercise of any other right, power
or privilege and no waiver will be valid unless in writing and signed by Bank
and then only to the

                                       14

extent specified. All remedies herein by law afforded will be cumulative and
will be available to Bank until payment in full of all sums due under the Loan
Documents. No omission or delay by the Borrower in exercising any right, power

construed to be a waiver or acquiescence therein and any single or partial
exercise of any right, power or privilege will not preclude other or further
exercise of any other right, power or privilege and no waiver will be valid
unless in writing and signed by Borrower and then only to the extent specified.
All remedies herein by law afforded will be cumulative.

                                CREDIT AGREEMENT

         THIS CREDIT AGREEMENT is made as of the 30th day of September, 1999, by
and among BHA GROUP HOLDINGS, INC., a Delaware corporation ("BORROWER"), BHA
GROUP, INC., a Delaware corporation, and BHA TECHNOLOGIES, INC., a Delaware
corporation (each a "GUARANTOR" and together "GUARANTORS"), and BANK OF AMERICA,
N.A., a national banking association (the "BANK").

         WHEREAS, Borrower has applied to the Bank for a three-year unsecured
revolving line of credit in the amount of $18,000,000; and

         WHEREAS, Borrower has applied to the Bank to make available, on the
request of Borrower, letters of credit to be applied against the amount
available under the revolving line of credit; and

         WHEREAS, the Bank has agreed to make such credit and loans available to
Borrower upon the terms and conditions set forth herein;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein, the parties agree as follows:

                                    ARTICLE 1
                                   DEFINITIONS

         Certain terms used in this Agreement are defined herein. Certain other
terms are defined in Exhibit 1 attached hereto and incorporated herein by this
reference.

                                    ARTICLE 2
                            REVOLVING LINE OF CREDIT

         2.1 Agreement to Lend.

                  (1) The Bank agrees, on the terms and subject to the
conditions set forth in this Agreement, to make loans (each a "REVOLVING LOAN")
to Borrower from time to time beginning on the Closing Date and ending on the
Revolving Credit Termination Date, in such amounts as Borrower shall request as
provided in Section 4.8 hereof and to treat each draw under any Letter of Credit
as a Revolving Loan as provided in Section 3.1 below; provided, however, that
the Bank shall have no obligation to make a requested Revolving Loan if, after
the making of such Revolving Loan, (i) the aggregate unpaid principal balance of
all Revolving Loans, together with the aggregate undrawn amount under all
outstanding Letters of Credit, would exceed the Revolving Credit Commitment;
(ii) a Default or Event of Default has occurred and is continuing; or (iii) the
Loan requested is a Eurodollar Rate Loan and the requested Eurodollar Rate
election would cause more than five (5) Eurodollar Rate Loans to be outstanding.
Borrower may terminate or reduce the unused portion of






<PAGE>


the Revolving Credit Commitment at any time by giving notice to the Bank as
provided in Section 4.8 below, provided that any partial reduction shall be in
an amount of at least $1,000,000. Revolving Loans shall be used to pay existing
indebtedness to the Bank, for working capital, for Acquisitions up to an
aggregate of $3,000,000 during the term of this Agreement, to purchase or redeem
its own stock and for other corporate purposes.

                  (2) If the aggregate principal indebtedness of Borrower under
the Revolving Note (as defined below), plus the aggregate undrawn amount under
all outstanding Letters of Credit, at any time exceeds the Revolving Credit
Commitment, Borrower shall immediately, without demand or notice, pay principal
under the Revolving Note so that the aggregate principal amount outstanding
thereunder, plus the aggregate undrawn amount under all outstanding Letters of
Credit, does not exceed the Revolving Credit Commitment.

         2.2 Revolving Note. The Revolving Loans shall be evidenced by and
repaid in accordance with a Revolving Credit Note executed by Borrower, in the
form of Exhibit 2.2 hereto, dated as of the Closing Date, and payable to the
order of the Bank. Such note and any and all amendments, extensions,
modifications, renewals, reaffirmations, restatements, replacements and
substitutions thereof and therefor are herein referred to as the "REVOLVING
NOTE." Interest shall accrue on the unpaid principal balance of the Revolving
Note outstanding from time to time at a rate or rates determined as provided in
Section 4.3 below. The Revolving Note shall be paid in full on the Revolving
Credit Termination Date.

                                    ARTICLE 3
                             OTHER CREDIT FACILITIES

         3.1 Letters of Credit. From time to time after the date hereof until
the Revolving Credit Termination Date, Borrower may apply to the Bank to issue
or extend the expiration date of one or more standby letters of credit for the
account of Borrower (all such letters of credit, together with all letters of
credit issued by the Bank for the account of Borrower outstanding on the date of
this Agreement and all renewals and extensions of any thereof, "LETTERS OF
CREDIT"), each of which:

                  (1) shall be for a stated amount which, together with the
aggregate undrawn amount then outstanding under all Letters of Credit and the
principal amount then outstanding of all Revolving Loans, does not exceed the
Revolving Credit Commitment;

                  (2) shall, by its terms, not exceed a term of one year and
shall expire not later than the Revolving Credit Termination Date;

                  (3) shall require payment by Borrower of fees as described in
Section 5.2 hereof (such fees are not, however, applicable to any Letters of
Credit outstanding prior to the date of this Agreement but they are applicable
to any renewals or extensions thereof); and

                  (4) shall be issued, to the extent applicable, pursuant to the
Bank's then-current standard form of application for letters of credit.


                                       2







<PAGE>


Borrower authorizes and directs the Bank to cause the repayment of each draw
under the Letters of Credit to be made immediately by charging such repayment
against the Revolving Note as a Prime Rate Loan.

         3.2 CONVERSION OF REVOLVING LOANS. Borrow may convert all or any
portion of the outstanding Revolving Loans to a loan with a fixed rate of
interest pursuant to an interest rate swap agreement or other similar agreement
that has terms and conditions acceptable to the Bank. The effective fixed rate
offered by the Bank will be based upon market conditions on the date of the
closing of any swap. Borrower may, at any time, prepay all or any portion of
such a converted loan, without premium or penalty; if Borrower prepays any such
loan, Borrower shall pay all fees and expenses associated with unwinding any
interest rate swap.

                                    ARTICLE 4
                TYPES OF LOANS; DISBURSEMENTS; INTEREST; PAYMENTS

         4.1 Types of Loans. The Loans made on each Disbursement Date may,
subject to the terms and conditions of this Agreement, be Prime Rate Loans or
Eurodollar Rate Loans (each being referred to as a "type" of Loan) as specified
in the applicable request for borrowing referred to in Section 4.8 hereof, and
Borrower may convert Loans of one type into Loans of the other type or continue
Loans of one type as Loans of the same type, at any time or from time to time,
provided that if any Eurodollar Rate Loan is converted on any day other than the
last day of the Interest Period for such Loan, Borrower shall pay all applicable
fees and amounts described in Section 5.3 below.

         4.2 Loan Disbursement Procedures.

                  (1) Loans shall be disbursed by the Bank upon request by
Borrower from time to time on or after the Closing Date, in such amounts as is
requested as provided in Section 4.8 below or as provided in Section 3.1 above,
subject to the limitations on the Bank's obligations to make Loans as set forth
in Section 2.1 hereof. Subject to the terms of this Agreement, Borrower may
borrow, repay and reborrow Revolving Loans at any time prior to the Revolving
Credit Termination Date.

         Each request for a Loan shall be delivered to the Bank in writing or by
telex or facsimile transmission in the manner provided in Section 12.1 hereof,
or as otherwise agreed by the Bank, not later than 1:00 p.m., Kansas City,
Missouri time, on the date on which Borrower desires disbursement of the Loan,
which date shall be a Business Day and shall be specified in the request (a
"DISBURSEMENT DATE"). The Bank may rely and act upon any such request which is
received from a person believed by the Bank in good faith to be authorized to
make such request on behalf of Borrower. The Bank shall record in its records
all Loans made by the Bank to Borrower pursuant to this Agreement and all
payments made on the Loans.

         4.3 Interest.

                  (1) Borrower shall pay to the Bank interest on the unpaid
principal amount of each Revolving Loan for the period commencing on and
including the date of such Loan to but excluding the date such Loan is paid in
full, at the following rates per annum:

                           (i) during any period while such Loan is a Prime Rate
         Loan, the Prime Rate (as in effect from time to time) less 1%; and

                           (ii) during any period while such Loan is a
         Eurodollar Rate Loan, for each Interest Period relating thereto, the
         Eurodollar Rate for such Interest Period plus the Applicable Margin in
         effect on the Disbursement Date, the date of conversion or the date of
         continuation, as applicable and as adjusted as provided in this
         Agreement. The "APPLICABLE MARGIN" will be .85% from the date of this
         Agreement to and including September 30, 2000. Thereafter, the
         "APPLICABLE MARGIN" will be calculated and adjusted, as shown below, on
         the first day of the month following the receipt by the Bank of each
         quarterly Compliance Certificate; any change in the "APPLICABLE MARGIN"
         shall be effective with respect to Interest Periods beginning on or
         after each such date. The interest rate with respect to each
         outstanding Eurodollar Rate Loan shall not change during any Interest
         Period. On and after October 1, 2000, the Applicable Margin will be as
         follows:

Borrower shall pay interest at the Default Rate on any principal of any Loan and
on any interest or other amount payable by Borrower hereunder or under the Note
(i) that is not paid in full when due (whether at maturity, by acceleration or
otherwise), for the period commencing on and including the due date thereof
until the same is paid in full and (ii) upon and during the continuance of any
failure to comply with or violation of any of the financial covenants set forth
in Article 10 of this Agreement as shown on and as of the last day of a fiscal
quarter as reflected on any Compliance Certificate.

                  (3) Accrued interest on each Loan shall be payable (i) in the
case of a Prime Rate Loan, on the last Business Day of each calendar quarter,
and (ii) in the case of a Eurodollar Rate Loan, on the last day of each Interest
Period therefor; provided that interest payable at the Default Rate shall be
payable, to the extent applicable, from time to time on demand of the Bank.

                  (4) The Bank shall, as part of its interest statements, notify
Borrower of any change in the Prime Rate and of the Eurodollar Rates in effect
and shall, on the request of Borrower at any time, notify Borrower of the
Eurodollar Rate or Rates then in effect.

                  (5) In the event that Borrower fails to select the type of
Loan or the duration of any Interest Period for any Eurodollar Rate Loan within
the time period and otherwise as provided in Section 4.8, such Loan (if
outstanding as a Eurodollar Rate Loan) will be automatically converted into a
Prime Rate Loan on the last day of the then current Interest Period for such
Loan or (if outstanding as a Prime Rate Loan) will remain as, or will be made
as, a Prime Rate Loan.

         4.4 Optional and Mandatory Payments. Borrower shall have the right to
prepay the Loans in whole or in part at any time without premium or penalty,
subject to giving the Bank prior notice in accordance with the provisions of
Section 4.8 hereof, provided that (i) each such partial prepayment shall be in
the aggregate principal amount of not less than $100,000 with respect to Prime
Rate Loans and $500,000 with respect to Eurodollar Rate Loans, and (ii) if any
prepayment of a Eurodollar Rate Loan is made on any day other than the last day
of the Interest Period therefor, it may be prepaid only upon three (3) Business
Days prior notice to the Bank and Borrower shall pay to the Bank any applicable
fees and amounts described in Section 5.3(a) below. Amounts prepaid in respect
of Loans under this Section 4.4 may be reborrowed subject to the terms and
conditions hereof. Borrower shall make mandatory principal payments on the Loans
as provided in Section 2.1(b) above.

         4.5 Payments. Except as otherwise provided herein and subject to
Section 4.8 below, all payments of principal, interest, Fees, taxes, charges,
expenses and other items payable by Borrower hereunder and under the Note shall
be made in U.S. dollars and shall be credited on the date of receipt by the Bank
if received by the Bank at its principal office in Kansas City, Missouri, in
immediately available funds, prior to 1:00 p.m., Kansas City, Missouri time, on
a Business Day. Payments made in funds which are not immediately available shall
be credited only when the funds are collected by the Bank, and payments received
(whether from Borrower in immediately available funds or through the collection
of funds which were not immediately available at the time payment was tendered
by Borrower) after 1:00 p.m. will be credited on the next Business Day. The Bank
reserves the right to apply all payments received by it from Borrower and
designated or authorized to be applied to a Note first to any Fees and other
charges then due to the Bank, then to accrued interest on such Note and then to
reduction of the principal balance of such Note, or such other order as the Bank
may determine in its sole discretion. The Bank shall also record in its records,
in accordance with customary accounting practice, all interest, Fees, taxes,
charges, expenses and other items properly chargeable to Borrower with respect
to the Loans, all payments received by the Bank for application to the
Obligations, and all other appropriate debits and credits. The Bank's records
shall constitute prima facie evidence of the amount of Obligations outstanding
from time to time.

         4.6 Direct Debit and Pre-Billing.


                                       5






<PAGE>


         (a) Borrower agrees that Bank will debit deposit account number
020100039303 or such other of Borrower's accounts with the Bank as designated in
writing by either Borrower (the "DESIGNATED ACCOUNT") on the date each payment
of principal, interest and all other Obligations, including the fees described
in Section 5.2 and fees, amounts and costs described in Section 5.3, become due
(the "DUE DATE"). If the Due Date is not a Business Day, the Designated Account
will be debited on the next Business Day.

         (b) Approximately 10 days prior to each Due Date, Bank will mail to
Borrower a statement of the amounts that will be due on that Due Date (the
"BILLED AMOUNT"). The calculation will be made on the assumption that no new
extensions of credit or payments will be made between the date of the billing
statement and the Due Date and that there will be no changes in the applicable
interest rate.

         (c) Bank will debit the Designated Account for the Billed Amount,
regardless of the actual amount due on that date (the "ACCRUED AMOUNT"). If the
Billed Amount debited to the Designated Account differs from the Accrued Amount,
the discrepancy will be treated as follows:

                  (i) If the Billed Amount is less than the Accrued Amount, the
Billed Amount for the following Due Date will be increased by the amount of the
discrepancy. Borrower will not be in default and an Event of Default will not
occur by reason of any such discrepancy.

                  (ii) If the Billed Amount is more than the Accrued Amount, the
Billed Amount for the following Due Date will be decreased by the amount of the
discrepancy.

         Regardless of any such discrepancy, interest will continue to accrue
based on the actual amount of principal outstanding without compounding. Bank
will not pay Borrower interest on any overpayment.

         (d) Borrower will maintain sufficient funds in the Designated Account
to cover each debit. If there are insufficient funds in the Designated Account
on the date Bank enters any debit authorized by this Agreement, the debit will
be reversed.

         (e) Borrower may terminate this direct debit arrangement at any time by
sending written notice to Bank.

         4.7 Minimum Amounts. Each borrowing or conversion of Prime Rate Loans
shall be in an amount of at least $100,000 and each borrowing, conversion or
continuation of Eurodollar Rate Loans shall be in an amount of $500,000 or a
multiple of $100,000 in excess thereof.

         4.8 Certain Requests and Notices. Borrower will request borrowings and
give notice to the Bank of all terminations or reductions of Commitments,
conversions, continuations and prepayments of Loans and the duration of Interest
Periods, such requests and notices to be substantially in the form of Exhibits
4.8-A and 4.8-B hereto. Each such notice shall be irrevocable and shall be
effective only if received by the Bank not later than


                                       6






<PAGE>


1:00 p.m. Kansas City time (i) on the Business Day prior to the effective date
of the requested termination or reduction of a Commitment, (ii) on the same date
if it is a notice of a borrowing or prepayment of a Prime Rate Loan (except that
if such date is not a Business Date, then on the next Business Day), or (iii)
three (3) Business Days prior to the requested effective date for a borrowing or
prepayment of, conversion into or continuation as a Eurodollar Rate Loan or any
selection of Interest Period for a Eurodollar Rate Loan.

         For purposes of calculating the number of Business Days, the date the
notice is received shall be included if received not later than 1:00 p.m. Kansas
City time and excluded if received after 1:00 p.m. Kansas City time.

                                    ARTICLE 5
                          GUARANTIES; FEES; COLLATERAL

         5.1 Guaranties. At the Closing, the Guarantors are each delivering to
Bank a Guaranty Agreement in substantially the form of Exhibit 5.1. If Borrower
or any Subsidiary acquires or creates any subsidiary after the Closing Date or
if the Bank so requests with respect to any Subsidiary, Borrower shall cause
each such newly acquired or created Subsidiary and each such other Subsidiary to
become a Guarantor by causing it to deliver to the Bank (i) a Guaranty Agreement
executed by the Subsidiary in substantially the form attached hereto as Exhibit
5.1 with such additional matters included therein as may be required by the Bank
(whether delivered at the Closing or thereafter, each, a "LOAN GUARANTY"), (ii)
if requested by Bank, an opinion of such Subsidiary's counsel, satisfactory in
form and substance to the Bank, as to the enforceability of such Loan Guaranty
and other matters required by the Bank; such opinion shall be substantially the
same as the opinion delivered with respect to the initial Guarantors on the
Closing Date, with such additional matters included therein as may be required
by the Bank and shall include, if requested by the Bank, the opinion of counsel
from the Subsidiary's jurisdictions of organization and operation, and (iii)
copies of such Subsidiary's charter documents, certified by the appropriate
public official, and of its bylaws, certified by its secretary.

         5.2 Unused Commitment and Letter of Credit Fees. Borrower agrees to
pay a quarterly unused commitment fee equal to .25% of the unused Revolving
Credit Commitment; such fees shall be calculated daily. In making such
calculations, the unused Revolving Credit Commitment shall be reduced by the
undrawn amount of each outstanding Letter of Credit. Borrower shall pay the
unused Commitment fees with respect to each quarter within 15 days after the end
of such quarter.

         Borrower agrees to pay an initial issuance fee on the date that each
standby Letter of Credit is issued in an amount equal to .125% of the amount of
such Letter of Credit and to pay the Bank's then standard fee for any renewals
and extensions of any Letter of Credit. Borrower also agrees to pay a fee in an
amount equal to the Applicable Margin rate per annum times the undrawn amount of
all outstanding Letters of Credit; such fee will be calculated and paid on last
business day of each fiscal quarter and shall be subject, after October 1, 2000,
to appropriate adjustment after the Bank's receipt of Borrower's Compliance
Certificate respecting such quarter.


                                       7






<PAGE>


         All fees shall be calculated on a 360-day year basis, if applicable.

         5.3 Additional Eurodollar Rate Loan Costs.

                  (1) Borrower shall pay to the Bank from time to time, upon
request of the Bank, (i) such amounts as the Bank may determine to be necessary
to compensate it for any Additional Eurodollar Rate Loan Costs respecting
Regulatory Changes and (ii) an administrative fee of $300 plus such amounts as
the Bank may determine to be necessary to compensate it for any loss, cost or
expense which the Bank incurs (including, without limitation, any loss, cost or
expense incurred by reason of the liquidation or re-employment of deposits, but
excluding loss of anticipated profits) that is attributable to (A) any payment,
prepayment or conversion of a Eurodollar Rate Loan made by either Borrower for
any reason on a date other than the last day of an Interest Period for such Loan
or (B) any failure by either Borrower for any reason (including, without
limitation, the failure of any condition specified in Article 6 hereof to be
satisfied) to borrow, continue or convert a Eurodollar Rate Loan on the date
therefor specified in the request for borrowing or notice given pursuant to
Section 4.8 hereof. Such compensation may include an amount equal to the excess,
if any, of (i) the amount of interest which would have accrued on the amount so
prepaid, or not so borrowed, converted or continued, for the period from the
date of such prepayment or of such failure to borrow, convert or continue to the
last day of the applicable Interest Period (or, in the case of a failure to
borrow, convert or continue, the Interest Period that would have commenced on
the date of such failure) in each case at the applicable rate of interest for
such Loans provided for herein (excluding, however, the Applicable Margin
included therein, if any) over (ii) the amount of interest (as reasonably
determined by the Bank) which would have accrued to the Bank on such amount by
placing such amount on deposit for a comparable period with leading banks in the
interbank Eurodollar market. The covenants of Borrower set forth in this Section
5.3 shall survive the termination of this Agreement and the payment of the Loans
and all other amounts payable hereunder. The Bank will notify Borrower of any
event which will entitle the Bank to compensation pursuant to this Section 5.3
as promptly as practicable after the Bank determines to require such
compensation and will furnish Borrower with a certificate setting forth in
reasonable detail the basis and amount of such compensation.

                  (2) Determinations by the Bank of the effect of any Regulatory
Change on its rate of return or cost of maintaining the Eurodollar Rate Loans,
on its obligation to make Eurodollar Rate Loans or on amounts receivable by it
in respect of the Eurodollar Rate Loans and determinations of the amounts
required to compensate such Bank under this Section 5.3 shall be conclusive,
provided that such determinations are made on a reasonable basis and are set
forth in reasonable detail in the certificates referred to in Section 5.3(a)
above.

                  (3) Anything herein to the contrary notwithstanding, if it
becomes unlawful for the Bank to honor its obligation to make or maintain
Eurodollar Rate Loans hereunder or if, on or prior to the determination of any
Eurodollar Rate for any Interest Period, the Bank determines (which
determination shall be conclusive) that quotations of


                                       8






<PAGE>


interest rates for the relevant deposits referred to in the definition of
"Eurodollar Rate" in Exhibit 1 hereto are not being provided in the relevant
amounts or for the relevant maturities for purposes of determining rates of
interest for Eurodollar Rate Loans, then the Bank shall give Borrower prompt
notice thereof, and, so long as such condition remains in effect, the Bank shall
be under no obligation to make additional Eurodollar Rate Loans, to continue
Eurodollar Rate Loans or to convert Prime Rate Loans into Eurodollar Rate Loans,
and Borrower shall, on the last day(s) of the then current Interest Period(s)
for the outstanding Eurodollar Rate Loans, either prepay such Loans or convert
such Loans into Prime Rate Loans.

         5.4 COLLATERAL. The Note will be unsecured. All assets of Borrower,
Guarantors and other Subsidiaries will be subject to the negative pledge set
forth in Section 10.9 below.

                                    ARTICLE 6
                           CONDITIONS TO MAKING LOANS

         The Bank's obligation hereunder to make the Loans, extend credit and
enter into transactions referred to in Article 3 shall be subject to the
satisfaction of the following conditions on or prior to the Closing Date and, in
the case of the conditions set forth in Sections 6.4, 6.5, 6.6, 6.7 and 6.8, as

<PAGE>


becoming Subsidiaries as a result of an Acquisition) shall be true and correct
as though made on and as of the Closing Date or such Disbursement Date or such
date of issuance, renewal or extension of a Letter of Credit, as the case may
be, except that the representations and warranties set forth in the first
sentence of Section 7.4(b), Section 7.7 and the second sentence of Section 7.9
(which relate to disclosure schedules 7.4, 7.7 and 7.9) are not required by this
Section 6.4 to be made as of any Disbursement Date or date of issuance, renewal
or extension of a Letter of Credit. No Default or Event of Default shall have
occurred and be continuing. The Bank shall have received certifications of
Borrower in form satisfactory to the Bank and dated the Closing Date or the date
of the request for borrowing or for issuing, renewing or extending a Letter of
Credit, as applicable, certifying as to each matter set forth in this Section

connection with the transactions contemplated by this Agreement shall be
satisfactory in form and substance to the Bank and its counsel, and the Bank
shall have received copies of all other documents, including records of

in connection therewith, such documents where appropriate to be certified by
proper corporate or governmental authorities, and such other conditions shall
have been fulfilled as may have been requested by the Bank.

                                    ARTICLE 7
                         REPRESENTATIONS AND WARRANTIES

         Borrower, with respect to itself and with respect to each of the
Subsidiaries, and each of Guarantors, with respect to itself, represent and
warrant to the Bank that:


                                       10






<PAGE>


         7.1 Corporate Existence and Standing. Borrower is and each Subsidiary
is a corporation duly incorporated, validly existing and in good standing under
the laws of its jurisdiction of incorporation and has all requisite authority to
own its property and to carry on its business in each jurisdiction where the
failure to so qualify would have a material adverse effect on its business,
properties, assets, operations or condition (financial or otherwise).

         7.2 Authorization and Validity. Borrower has and each Guarantor has
the corporate power and authority and legal right to execute and deliver the
Loan Documents to which it is a party and to perform its obligations thereunder.
Such execution and delivery have been duly authorized by proper proceedings, and
the Loan Documents constitute the legal, valid and binding obligations of
Borrower and the Guarantors, enforceable against them in accordance with their
respective terms.

         7.3 No Conflict; Governmental Consent. The execution, delivery and
performance of the Loan Documents will not violate any law, rule, regulation,
order, writ, judgment, injunction, decree or award binding on Borrower or any
Subsidiaries, any provision of their respective articles or certificate of
incorporation, by-laws or other charter document, or the provisions of any
indenture, instrument or other written or oral agreement to which Borrower or
any Subsidiary is a party or is subject or by which Borrower or any Subsidiary
or any of their property is bound, or conflict therewith or constitute a default
thereunder, or result in the creation or imposition of any Lien in, of or on any
of their property pursuant to the terms of any such indenture, instrument or
agreement. No order, consent, approval, license, authorization or validation of,
or filing, recording or registration with, or exemption by, any Governmental
Authority is required to authorize or is required in connection with the
execution, delivery and performance of or the enforceability of any of the Loan
Documents.

         7.4 Compliance with Laws; Environmental and Safety Matters.

                  (1) Borrower has and each Subsidiary has complied with all
applicable statutes, rules, regulations, orders and restrictions of any domestic
or foreign government or Governmental Authority having jurisdiction over the
conduct of its businesses or the ownership of its respective properties except
to the extent that such non-compliance will not have a material adverse effect
on the financial condition or business operations of Borrower, on a consolidated
or unconsolidated basis, or of either Guarantor.

                  (2) Borrower and the Subsidiaries have each, except as
disclosed in Schedule 7.4 hereto and to Borrower's and Guarantors' actual
knowledge, complied with all federal, national, state, local and other statutes,
ordinances, orders, judgments, rulings and regulations relating to environmental
pollution, environmental regulation or control, or employee health or safety,
except to the extent that such non-compliance will not have a material adverse
effect on their respective financial conditions or business operations; they
have not received any written notice of any failure so to comply except as
disclosed in Schedule 7.4 hereto; and their facilities do not treat, store or
dispose of any hazardous wastes, hazardous substances, hazardous materials,
toxic substances, toxic pollutants or substances ("HAZARDOUS MATERIALS")
similarly denominated, as those terms or similar terms are used in


                                       11






<PAGE>


RCRA, CERCLA, the Hazardous Materials Transportation Act, the Toxic Substances
Control Act, the Clean Air Act, the Clean Water Act, the Occupational Safety and
Health Act or any other state, local or federal applicable law, ordinance, rule
or regulation relating to environmental pollution, environmental regulation or
control or employee health and safety ("ENVIRONMENTAL LAWS") in a quantity or
manner that requires a permit, registration, or another notification or
authorization from a Governmental Authority except for the treatment, storage,
or disposal of Hazardous Materials in a quantity or manner which, if in
non-compliance with Environmental Laws, would not have a material adverse effect
on their respective financial conditions or business operations except as
disclosed in Schedule 7.4 hereto. The conduct of the business and the condition
of the property of Borrower and each of the Subsidiaries do not violate any
Environmental Laws or any judicial interpretation thereof relating primarily to
the environment or Hazardous Materials. Neither Borrower nor any Subsidiary is
aware of any events, conditions or circumstances involving environmental
pollution or contamination or employee health or safety that could reasonably be
expected to result in material liability on the part of Borrower or any
Subsidiary.

         7.5 Financial Statements. Borrower has heretofore furnished to the
Bank its (a) consolidated balance sheet and related consolidated statements of
earnings and cash flows as of and for the fiscal year ended September 30, 1998,
and (b) an unaudited consolidated balance sheet and unaudited statements of
earnings and cash flows as of and for quarter ended June 30, 1999. Such
financial statements fairly state the consolidated financial condition and
results of operations of Borrower and the Subsidiaries as of such dates and for
such periods. Neither Borrower nor any of the Subsidiaries had on said date any
material (on a consolidated basis) contingent liabilities, material (on a
consolidated basis) liabilities for taxes, unusual forward or long-term
commitments or unrealized or anticipated losses from any unfavorable
commitments, except as referred to or reflected or provided for in said balance
sheet or the notes thereto as at said date. Such financial statements were
prepared in accordance with GAAP applied on a consistent basis. Since June 30,
1999, no material adverse change has occurred in the business, properties,
financial condition, prospects or results of operations of Borrower (on a
consolidated or unconsolidated basis) or of either Guarantor.

         7.6 Ownership of Properties; Collateral Liens. Borrower has and each
Subsidiary has good title, free and clear of all Liens (other than those
permitted by Section 10.2 hereof), to all of the properties and assets reflected
in its financial statements as owned by it, and its interest in all other
properties and assets in or to which it has an interest as a lessee, licensee or
otherwise is free and clear of all Liens (other than those permitted under
Section 10.2 hereof).

         7.7 Subsidiaries. Neither Borrower nor any Subsidiary has any
subsidiaries except as disclosed in Schedule 7.7. Except as described in
Schedule 7.7, all of the issued and outstanding shares of capital stock or other
ownership interests of each Subsidiary, have been duly authorized and issued to
Borrower or to a Subsidiary and are fully paid and non-assessable, free and
clear of all liens, restrictions and rights.


                                       12






<PAGE>


         7.8 Litigation. All litigation, arbitration, mediation, governmental
investigations, proceedings or inquiries before any Governmental Authority,
arbitrator or mediator that are pending or, to the knowledge of any of its
officers, threatened against or affecting Borrower or any Subsidiary (other than
those covered by insurance, but only to the extent so covered) are not
reasonably expected to exceed, in the aggregate, $750,000.

         7.9 Material Agreements; Labor Matters. Any agreement or instrument of
either Borrower or any Subsidiary that has or is likely to have a material
effect on the assets, prospects, business, operations, financial condition,
liabilities or capitalization of Borrower or Guarantor as a separate company or
of Borrower on a consolidated basis is referred to in this Section 7.9 as a
"MATERIAL CONTRACT." As of the date hereof, all of the Material Contracts are
listed on Schedule 7.9 hereto. Neither Borrower nor any Guarantor is in default
under any Material Contract in any manner that could materially and adversely
affect its assets, prospects, business, operations, financial condition,
liabilities or capitalization of or in any manner that could jeopardize its
right to require the performance, observance or fulfillment of any of the
obligations, covenants or conditions contained in any Material Contract. There
are no strikes or walkouts relating to any labor contracts with Borrower or any
Subsidiary pending or threatened, and no labor contracts are scheduled to expire
during the term of this Agreement, and no efforts are being made by any
employees to form a union or collectively bargain with Borrower or any
Subsidiary.

         7.10 Investment Company Act; Public Utility Holding Company Act.
Neither Borrower nor any Subsidiary is an "investment company" or a company
"controlled" by an "investment company," within the meaning of the Investment
Company Act of 1940, as amended, or a "holding company," a "subsidiary company"
of a "holding company" or an "affiliate" of a "holding company" or of a
"subsidiary company" of a "holding company," within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

         7.11 Taxes. Borrower has and each Subsidiary has filed all United
States federal tax returns and all other tax returns which, to Borrower's or
either Guarantor's actual knowledge, are required to be filed and paid all taxes
due pursuant to said returns or pursuant to any assessment received by it,
including without limitation all federal and state withholding taxes and all
taxes required to be paid pursuant to applicable law, except such taxes, if any,
as are being contested in good faith, by appropriate proceedings and as to which
adequate charges, accruals and reserves have been set aside. No tax Liens have
been filed, and no claims are being asserted with respect to any such taxes,
except such tax Liens and claims that will not have a material adverse effect,
individually or in the aggregate, on the assets, business, operations or
financial condition of Borrower or either Guarantor, on a consolidated or
unconsolidated basis. The charges, accruals and reserves on the books of
Borrower, on a consolidated basis, in respect of any taxes or other governmental
charges are adequate.

         7.12 Accuracy of Information. No information, exhibit or report
furnished by Borrower or any Subsidiary to the Bank in connection with the
negotiation of the Loan Documents contained any material misstatement of fact or
omitted to state a material fact or any fact necessary to make the statements
contained therein not misleading.


                                       13






<PAGE>


         7.13 Employee Benefit Plans. Neither Borrower nor any Subsidiary
maintains, sponsors or contributes to any Defined Benefit Pension Plan.

         7.14 No Undisclosed Dividend Restrictions. Except for limitations on
the payment of dividends under applicable corporate statutes, neither Borrower
nor any Subsidiary is subject to any agreement, covenant or understanding that
limits or restricts its ability to declare or pay dividends.

         7.15 Absence of Default or Event of Default. No Default and no Event of
Default has occurred and is continuing.

         7.16 Disclosure. The pro forma financial information contained in
financial statements delivered to the Bank will be based upon good faith
estimates and assumptions believed by Borrower to be reasonable at the time
made. There is no fact known to Borrower (other than matters of a general
economic nature) that has had or could reasonably be expected to have a material
adverse effect and that has not been disclosed herein or in such other
documents, certificates and statements furnished to the Bank for use in
connection with the transactions contemplated by this Agreement.

         7.17 Solvency. Based upon its financial and accounting records,
Borrower has and each Subsidiary has assets of a value that exceeds the amount
of its liabilities (excluding, for purposes of this representation, all
intercompany loans from liabilities). Borrower reasonably anticipates that it
and each of its Subsidiaries will be able to meet their respective debts as they
mature. Borrower and each Subsidiary have adequate capital to conduct the
business in which it is engaged.

         7.18 Margin Regulations. Neither the making of the Loans hereunder, nor
the use of the proceeds thereof, will violate or be inconsistent with the
provisions of Regulation G, T, U or X of the Board of Governors of the Federal
Reserve System. No part of the proceeds of any Loan will be used, whether
directly or indirectly, and whether immediately, incidentally or ultimately, to
purchase or to extend credit to others for the purpose of purchasing or carrying
Margin Stock (as defined in said Regulation U).

         7.19 Copyrights, Patents and Other Rights. Borrower possesses and each
Subsidiary possesses all licenses, patents, patent rights and patent licenses,
trademarks, trademark rights and licenses, trade names, copyrights and all other
intellectual property rights which are required or desirable to conduct its

         7.20 Year 2000 Compliance. Borrower has (a) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by material suppliers and vendors) that
could be adversely affected by the risk that computer applications used by
Borrower or any Subsidiary or any of such suppliers and


                                       14

vendors may be unable to recognize and properly perform date-sensitive functions
involving certain dates prior to and any date after December 31, 1999 (the "YEAR
2000 PROBLEM"), (b) developed a plan and time line for addressing the Year 2000
Problem on a timely basis, and (c) implemented that plan in accordance with that
timetable. Borrower reasonably believes that all computer applications
(including those of its suppliers and vendors) that are material to its or any
of its Subsidiaries' business and operations will on a timely basis be able to
perform properly date-sensitive functions for all dates before and after January
1, 2000 (that is, be "YEAR 2000 COMPLIANT"), except to the extent that a failure
to do so could not reasonably be expected to have material adverse effect on the
financial condition or operations of Borrower, on a consolidated or
unconsolidated basis, or of either Guarantor.

accrued interest on any Loan or any other Obligations are outstanding.

         12.3 Binding Effect. This Agreement shall become effective when it
shall have been executed by Borrower, Guarantors and the Bank and thereafter
shall be binding upon and inure to the benefit of Borrower, Guarantors, the Bank

         12.5 Expenses; Indemnity.

                  (1) Borrower agree to pay all out-of-pocket expenses incurred
by the Bank in connection with the preparation of this Agreement and the other
Loan Documents or in connection with any amendments, modifications or waivers of
the provisions hereof or thereof (whether or not the transactions hereby
contemplated shall be consummated) or incurred by the Bank in connection with
the enforcement or protection of its rights in connection with this Agreement
and the other Loan Documents or in connection with the Loans made or the Note
issued hereunder, including, but not limited to, all appraisal fees (equipment
or otherwise), filing fees and search fees, the fees, charges and disbursements
of Lathrop & Gage L.C., counsel for the Bank, and, in connection with any such
amendment, modification or waiver or any such enforcement or protection, the
fees, charges and disbursements of any other counsel for the Bank. Borrower
further agrees that it shall indemnify the Bank from and hold it harmless
against any documentary taxes, assessments or charges made by any Governmental
Authority by reason of the Loans or this Agreement or any of the other Loan
Documents.

                  (2) Borrower agree to indemnify the Bank and its directors,
officers, employees and agents (each such person being called an "INDEMNITEE")
against, and to hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including reasonable counsel fees,
charges and disbursements, incurred by or


                                       26






<PAGE>


asserted against any Indemnitee arising out of, in any way connected with, or as
a result of (i) the execution or delivery of this Agreement or any other Loan
Document or any agreement or instrument contemplated thereby, the performance by
the parties thereto of their respective obligations thereunder or the
consummation of the transactions contemplated thereby, (ii) the making of any
loans or the use of the proceeds of the Loans or (iii) any claim, litigation,
investigation or proceeding relating to any of the foregoing, whether or not any
Indemnitee is a party thereto; provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses (i) are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the
negligence or wilful misconduct of such Indemnitee and (ii) have not, in whole
or in part, arisen out of or resulted from any act, or omission to act, of
either Borrower or any of their Affiliates.

                  (3) The provisions of this Section 12.5 shall remain operative
and in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document or any investigation made
by or on behalf of the Bank. All amounts due under this Section 12.5 shall be
payable on written demand therefor.

         12.6 Right of Setoff. If an Event of Default shall have occurred and be
continuing, the Bank is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by the Bank to or for the credit or the
account of Borrower or either Guarantor against any and all of the Obligations,
irrespective of whether or not the Bank shall have made any demand under this
Agreement or such other Loan Document and notwithstanding that such Obligations
may be unmatured. The rights of the Bank under this Section 12.6 are in addition
to other rights and remedies (including other rights of setoff) which the Bank
may have.

         12.7 Applicable Law. This Agreement and the other loan documents shall
be governed by and construed and enforced under and in accordance with the laws
of the State of Missouri applicable to contracts made and to be performed wholly
within said state, without giving effect to choice of law or conflict of law
principles.

         12.8 Waivers; Amendment. No failure or delay of the Bank in exercising
any power or right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right or power preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Bank hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies which they would
otherwise have. No waiver of any provision of this Agreement or any other Loan
Document or consent to any departure by Borrower or either Guarantor therefrom
shall in any event be effective unless the same shall be contained in a written
instrument signed by the Bank, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice or demand on Borrower in


                                       27






<PAGE>


any case shall entitle Borrower or any Subsidiary to any other or further notice
or demand in similar or other circumstances.

         12.9 Interest Rate Limitation. Notwithstanding anything herein or in
the Note to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "CHARGES"), as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by the Bank, shall exceed the maximum lawful rate (the
"MAXIMUM RATE") which may be contracted for, charged, taken, received or
reserved by the Bank in accordance with applicable law, the rate of interest
payable under the Note, together with all Charges payable to the Bank, shall be
limited to the Maximum Rate.

         12.10 Entire Agreement. This Agreement and the other Loan Documents
constitute the entire contract between the parties relative to the subject
matter hereof. Any previous agreement among the parties with respect to the
subject matter hereof is superseded by this Agreement and the other Loan
Documents. Nothing in this Agreement or in the other Loan Documents, expressed
or implied, is intended to confer upon any party other than the parties hereto
and thereto any rights, remedies, obligations or liabilities under or by reason
of this Agreement or the other Loan Documents.

         12.11 Severability. In the event any one or more of the provisions
contained in this Agreement or in any other Loan Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby. The parties shall endeavor in
good faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

         12.12 Counterparts. This Agreement may be executed in two or more
counterparts, all of which when taken together shall constitute but one
contract, and shall become effective as provided in Section 12.3.

         12.13 Headings. Section headings and the Table of Contents used herein
are for convenience of reference only, are not part of this Agreement and are
not to affect the construction of, or to be taken into consideration in
interpreting, this Agreement.

         12.14 Jurisdiction; Consent to Service of Process.

                  (1) Borrower and each Guarantor hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of any Missouri state court or the federal court for the Western

Documents or for recognition or enforcement of any judgment, and each of the
parties hereto

<PAGE>


hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such Missouri state or,
to the extent permitted by law, in such federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Bank may otherwise have to bring any action or proceeding
relating to this Agreement or the other Loan Documents against Borrower or any
Subsidiary or its properties in the courts of any jurisdiction.

                  (2) Borrower and each Subsidiary hereby irrevocably and
unconditionally waive, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this agreement or
the other Loan Documents in any Missouri state court or federal court for the
Western District of Missouri. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

                  (3) Each party to this Agreement irrevocably consents to
service of process in the manner provided for notices in Section 12.1. Nothing
in this Agreement will affect the right of any party to this Agreement to serve
process in any other manner permitted by law.
